Definitions
- the invention relates to footwear, i.e., shoes or boots, including footwear for one or more sports, and more particularly to footwear intended for activities such as skiing, hiking, walking, and athletics, although not limited thereto.
- Footwear of this type can be used in fields such as cross-country or telemark skiing, walking or running on flat or mountainous terrain, hiking, snowboarding, snowshoeing, roller skating, skateboarding, cycling, ball-playing sports, and the like.
- a boot can include a low upper or a high upper, or even a mid-upper.
- a boot can also be relatively flexible or, on the contrary, more rigid. However, it is in any case desirable that the user's foot be adequately held within the boot. Indeed, a foot properly held in the upper allows for a better use of the boot.
- a device for tightening the upper is adapted to hold the foot of the user.
- a tightening device includes a linkage, such as a lace, on the one hand, and connections for the lace to the upper. These connections are defined as keepers, associated with lateral and medial portions or quarters of the upper.
- the lace follows a path that leads it alternatively from one quarter to the other. Thus, it suffices to draw on the lace in order to bring the quarters closer to one another and to tighten the upper. The lace is then blocked to maintain the tightening.
- a problem that a good tightening device should seek to overcome is holding the foot thoroughly inside the boot. In other words, undesirable movements of the foot in the boot should be avoided, in particular in the area of the heel.
- the boot includes a tightening device, as mentioned above, on the one hand, and a structure for tightening the heel. Nevertheless, it has been noted once again that the foot sometimes is not held thoroughly.
- a boot according to the prior art does not always provide sufficient comfort of use, or that it is not easy to handle, particularly with respect to actuating the tightening devices and mechanisms.
- the invention includes a structure that improves foot retention in an article of footwear, such as a boot or, in other words, to reduce, or even to eliminate, undesirable displacements of the foot within the article of footwear or boot.
- the invention provides the boot with greater comfort, in static mode as well as in dynamic mode. It is indeed advantageous for the user to have a pleasant sensation, whether while standing still or while moving, such as, for example, during cross-country skiing or walking, or while engaged in similar activities. It is also advantageous to be able to easily handle the elements that activate or de-activate the tightening of the upper.
- an article of footwear according to the invention includes structure and arrangement that improves the fitting and/or removal of the article of footwear relative to the foot, in the sense that it is desirable to enable the foot to be inserted in or removed from the upper of the article of footwear more easily.
- the invention includes an article of footwear that includes a sole and an upper, the boot extending lengthwise from a rear end to a front end, widthwise between a lateral portion and a medial portion, and heightwise from the sole up to an upper end, the article of footwear of the invention having an opening for foot insertion, and including a first tightening device for tightening the lateral and medial portions, as well as a second tightening device for tightening a rear portion.
- An article of footwear according to the invention also includes a second tightening device that includes a linkage, such as a lace or filiform element, the linkage including a first inextensible portion and an elastic mechanism, the first inextensible portion extending along the rear portion, as well as along at least one of the lateral and medial portions, the elastic mechanism biasing the first inextensible portion in a direction reducing the length of the linkage, the article of footwear further including a reversible immobilization mechanism to immobilize the inextensible portion with respect to the upper.
- a linkage such as a lace or filiform element
- the second tightening device is structured and arranged to tighten the heel of the foot prior to tightening the upper. This involves wedging the heel before tightening the first tightening device. The wedging reduces or even eliminates the clearances between the foot heel and the upper, or between the foot heel and the linkage of the second tightening device. As a result, there are limited or no undesirable movements of the heel of the foot in the upper once tightening has been carried out.
- a resulting advantage is that the foot is held more efficiently in the upper, in the sense that undesirable movements of the foot with respect to the upper are markedly reduced, or even eliminated, in particular in the area of the heel. In other words, foot retention is more precise.
- an article of footwear according to the invention is more comfortable, whether in static mode or in dynamic mode. This results in particular from a better connection of the foot to the upper.
- the action of the elastic mechanism of the second tightening device improves comfort in handling the elements that activate or inactivate the tightening of the upper. Such improvement results from reducing the operations for managing the tightening, as the elastic mechanism manages part of the tightening.
- Another advantage of the invention is to enable the foot to be inserted in or removed from the upper more easily. Indeed, such greater ease is made possible by the elastic mechanism.

- FIG. 12 is a cross-section along the line XII-XII of FIG. 11 .
- the first embodiment which is described hereinafter, relates more particularly to boots adapted for cross-country or telemark skiing.
- the invention applies to other fields, such as those mentioned hereinabove.
- the term “boot” is used herein for convenience and the invention is not to be considered limiting by such use. Indeed, the invention encompasses boots, shoes, and other articles of footwear, whether such footwear have low uppers (for which the top of the upper extends beneath the ankle), high uppers (for which the top of the upper extends above the ankle), or mid-uppers (for which the top of the upper extends at the ankle).
- the first embodiment is described hereinafter with reference to FIGS. 1 to 8 .
- a cross-country ski boot is adapted to receive the foot of the user or wearer.
- the boot 1 includes a walking sole 2 , i.e., an external sole, and an upper 3 .
- the boot 1 extends lengthwise from a rear end, or heel 4 , to a front end, or tip 5 ; and widthwise between a lateral side 6 and a medial side 7 .
- the upper 3 includes a lower portion 10 , adapted to surround the foot, as well as an upper portion 11 , adapted to surround, i.e., cover, the ankle.
- an upper including only the lower portion 10 is within the scope of the invention.
- the boot 1 extends heightwise from the sole 2 to an upper end 12 , i.e., up to the free end of the upper portion 11 or of the upper 3 .
- the boot 1 includes a lateral portion 15 , a medial portion 16 , as well as a rear portion 17 .
- the boot 1 here includes an envelope 18 , which surrounds the ankle and covers the wear's foot while extending in the area of the portions 15 , 16 , 17 .
- the envelope 18 demarcates an opening 19 , in the area of the upper end 12 , adapted to allow the foot therethrough and also to surround the ankle after the foot has been inserted within the boot.
- the envelope 18 is continuous along the opening 19 .
- the envelope 18 is partially or entirely elastically deformable.
- the envelope 18 can be comprised of an elastic fabric.
- the perimeter of the opening is variable, and, for example, it can increase reversibly at the time the user's foot is passing through. This makes it possible to put on or take off the boot, but it also enables the envelope to closely fit the lower leg. A resulting advantage is increased resistance to the penetration of foreign objects in the upper. In particular, undesirable penetration of snow is avoided.
- the upper 3 is structured to enable a good flexion of the leg or a good rolling movement of the foot, as well as the transmission of sensory information or steering impulses.
- the sole can be relatively rigid, for example for practicing skating steps, or more flexible, for example for practicing alternative steps to thereby be structured to practice the two popular techniques known in the art.
- the portions 15 , 16 , 17 are affixed to the sole using known techniques, such as an adhesive, stitching, or any technique equivalent for this purpose.
- the structure of the upper described for the first embodiment of the invention is not limiting.
- the opening 19 instead of extending strictly in the area of the upper end 12 , could be provided to extend between the portions 15 , 16 towards the front end 5 .
- the boot can include a tongue between the portions 15 , 16 .
- the boot 1 includes a flap 25 structured and arranged to reversibly cover the lower portion 10 .
- the flap 25 extends from one portion 15 , 16 to the other, in order to improve imperviousness of the boot.
- the flap 25 is affixed to the medial portion 16 .
- a reversible closure 26 makes it possible to also affix the flap 25 to the lateral portion 15 .
- the reversible closure 26 includes a zipper or other slide fastener.
- any other structure could be provided to make the closure, such as a series of snap fasteners, for example.
- the boot 1 further includes a first tightening device 30 , adapted to reversibly tighten the upper 3 . More specifically, the tightening device 30 tightens the lateral portion 15 and medial portion 16 . According to the first embodiment, the first tightening device 30 tightens the envelope 18 .
- the tightening device 30 includes a linkage 31 .
- This linkage is divided into a first strand 32 and a second strand 33 , which are co-extensive, i.e., they are formed from a single linkage.
- the tightening device 30 further includes connections 34 to 41 (which can also be referred to as keepers or guides) for the strands 32 , 33 , i.e., of the linkage 31 , to the upper.
- the device 30 includes four lateral connections 34 to 37 , as well as four medial connections 38 to 41 .
- the device 30 includes a blocking mechanism 42 , not described here as it is well-known to the one with ordinary skill in the art.
- the blocking mechanism 42 acts on the two strands 32 , 33 of the linkage 31 .
- a blocking device could be used, such as disclosed in U.S. Pat. No. 5,477,593, the disclosure of which is hereby incorporated by reference thereto in its entirety.
- the linkage 31 can take the form of a lace, a string, or other filiform element, and the connections 34 to 41 can be comprised of hooks or keepers, such as open guides, as shown. All of the connections 34 to 41 are sliding connections, which promote a balancing of the tightening tensions.
- the tightening device of this practical implementation is not considered to limit the invention.
- the tightening device 30 can be regarded as a first tightening device.
- the boot 1 also includes a second tightening device 50 .
- the second tightening device 50 includes a linkage 51 , the linkage 51 including a first inextensible portion 52 and an elastic mechanism 53 , the first inextensible portion 52 extending along the rear portion 17 of the boot 1 , as well as along at least one of the lateral portion 15 and the medial portion 16 , the elastic mechanism 53 biasing the first inextensible portion 52 in a direction reducing the length of the linkage 51 , the boot 1 further including a reversible immobilization mechanism 54 for immobilizing the inextensible portion 52 , at least lengthwise, with respect to the upper 3 .
- the elastic mechanism 53 biases the linkage 51 in a direction tightening the heel of the wearer, either directly, or via the upper 3 .
- the linkage 51 closely encircles the elastically deformable envelope 18 of the boot in the area of the lateral 15 , rear 17 , and medial 16 portions.
- the first inextensible portion 52 extends along the lateral portion 15 , rear portion 17 and medial portion 16 . This limits, or even avoids, movement of the heel of the foot heel in the upper. Consequently, the undesirable movements of the foot in the upper are markedly or even completely avoided. Foot retention is more precise, which allows a more precise transmission of support forces and sensory information.
- the inextensible portion 52 includes a first segment 60 , or immobilization segment, as well as a second segment 61 , or constriction segment.
- Each segment 60 , 61 is a subdivision of the inextensible portion 52 .
- the first segment 60 includes a rack 62 , i.e., an element which includes a series of teeth 63 and recesses 64 .
- the rack 62 has a length extending from a first end 65 and a second end 66 , a width extending from a first edge 67 to a second edge 68 , and a thickness extending from an inner surface 69 to an outer surface 70 , the inner surface 69 facing the upper 3 .
- the rack 62 is a band, which is lengthwise inextensible although sufficiently flexible to bend, as shown in the drawing, along a transverse axis Wo (see FIG. 7 , e.g.).
- a transverse axis extends from the first edge 67 to the second edge 68 edge.
- the first segment 60 i.e., the rack 62 , for example, is made from a plastic material, such as polyethylene, polyamide, polyurethane, or any equivalent.
- the teeth 63 are directed so as to project in the area of an edge, for example the first edge 67 . Consequently, the recesses 64 extend through the rack 62 , i.e., the first segment 60 , from the inner surface 69 to the outer surface 70 .
- the second segment 61 includes, for example, a strap 74 that extends lengthwise between a first end 75 and a second end 76 , widthwise between a first edge 77 and a second edge 78 , and depthwise between an inner surface 79 and an outer surface 80 .
- the inner surface 79 is turned towards the upper 3 .
- the strap 74 is inextensible lengthwise and flexible along a transverse axis. Such an axis extends from the first edge 77 to the second 78 edge. The flexibility of the strap 74 enables it to closely follow the curvature of the upper 3 .
- the second segment 61 i.e., the strap 74 , for example, is made with fibers impregnated within a plastic material, woven or nonwoven fibers, or a band of synthetic material.
- the first segment 60 and second segment 61 prolong one another so as to extend around the heel 4 .
- the second end 66 of the rack 62 is affixed to the first end 75 of the strap 74 by an attachment medium or element, such as an adhesive, stitching, or any equivalent.
- the second end 76 of the second segment 61 is affixed to the upper 3 , on the medial side 7 , on the envelope 18 .
- the second end 76 is affixed by any means, such as stitching, an adhesive, or any equivalent.
- the end 76 is therefore permanently affixed to the upper 3 , i.e., to the envelope 18 , in this case.
- the end 76 could be made removable from the upper.
- the inextensible portion 52 of the linkage 51 can slide with respect to the upper 3 , outside of the upper.
- the inextensible portion 52 is tensionally biased by the elastic mechanism 53 , as explained hereinafter.
- the elastic mechanism in this case includes an elastic band 84 that extends lengthwise from a first end 85 to a second end 86 , widthwise between a first edge 87 and a second edge 88 , and depthwise between an inner surface 89 and an outer surface 90 .
- the inner surface 89 is turned towards the upper 3 .
- the band 84 is reversibly extensible, at least lengthwise.
- the band 84 is in fact made of an elastically extensible fabric including rubber threads, for example, or equivalent materials.
- the first end 85 of the band 84 is removably and adjustably affixed to the upper 3 , by an attachment mechanism 91 that includes, for example, a fabric portion 92 connected to the band 84 and a fabric portion 93 connected to the upper.
- an attachment mechanism 91 that includes, for example, a fabric portion 92 connected to the band 84 and a fabric portion 93 connected to the upper.
- these portions are being merely referenced, inasmuch as they are well-known to one with ordinary skill in the art.
- one of the two can take the form of loops and the other of the two can take the form of hooks, the loops and hooks being reversibly engageable for selective retention therebetween, such as known, e.g., as Velcro® brand hook and loop fasteners. It is therefore possible to arrange the first end 85 a little closer to the front end 5 or a little closer to the rear end 4 with respect to a referential position.
- the tension in the linkage 51 can thereby be selectively adjustable.
- the second end 86 of the band 84 is affixed to the first end 65 of the rack 62 .
- the attachment is made by any appropriate arrangement for such purpose, such as by stitching, an adhesive, or the like. This is, for example, and for practical purposes, a permanent, non-removable attachment.
- the invention encompasses an attachment that is intended to be temporary, i.e., one that is removable with or without a tool.
- the linkage 51 extends from the first end 85 of the elastic mechanism 53 , or the band 84 , to the second end 76 of the second segment 61 , or the strap 74 .
- the ends 85 , 76 of the linkage 51 are in asymmetrical and transverse arrangement. Indeed, the first end 85 of the band 84 is located in the front half of the boot 1 , for example in the area of the metatarsus and halfway between the sole 2 and the crest 98 thereabove. The crest 98 is the line that demarcates the limit between the lateral portion 15 and the medial portion 16 .
- the second end 76 is located in the rear half of the boot 1 , for example in the area of the ankle. The second end 76 is further away from the sole 2 than the first end 85 . For this reason, the linkage 51 extends in a tightening plane T inclined with respect to a plane S related to the sole 2 , according to a particular angle ⁇ (see FIG.
- the plane S is that which extends along the sole 2 , when the sole has its natural unstressed shape.
- the angle ⁇ ranges between 10° and 50°; values ranging from 20° to 35° yield good results. This means that the heel of the foot is efficiently retained against the sole 2 by means of the linkage 51 . The retention is effective as soon as the reversible immobilization mechanism 54 is actuated, as described below.
- the immobilization mechanism 54 includes a guide 101 , a tab 102 , and a locking finger 103 .
- the guide 101 is adapted to guide the position and movement of the inextensible portion 52 , in this case the first segment 60 .
- the guide 101 includes an inner wall 104 , opposite the upper 3 , as well as an outer wall 105 , which is opposite thereto.
- the inner wall 104 and outer wall 105 are connected to one another by a lower bridge 106 and an upper bridge 107 .
- the lower bridge 106 is referred to as such because it is closer to the sole 2 than the upper bridge 107 .
- the walls 104 , 105 and the bridges 106 , 107 demarcate a passage 108 , through which the first segment 60 extends.
- the passage 108 has a rectangular cross section; but it could be oblong, oval, or have any other shape.
- the guide 101 is located on the lateral portion 15 , between the sole 2 and the opening 19 .
- the guide 101 could be located on the medial portion 16 .
- the tab 102 extends from a connecting end 109 to a fastening end 110 .
- the connecting end 109 is affixed to the guide 101
- the fastening end 110 is affixed to a portion of the upper 3 adjacent, for example, the sole 2 .
- the tab 102 can be omitted.
- the guide 101 is directly affixed to the upper 3 , i.e., to the envelope 18 , such attachment being accomplished by any appropriate expedient, such as an adhesive or stitching, or the like.
- the guide 101 and the tab 102 form a unitary element made, for example, out of a plastic material.
- the attachment of the fastening end 110 , and therefore of the immobilization mechanism 54 , to the upper 3 is accomplished using an adhesive, stitching, or any equivalent.
- the tab 102 is therefore permanently connected to the upper 3 , which implies that the immobilization mechanism 54 is non-removably mounted to the boot 1 .
- the guide 101 comes in contact with the upper 3 by being supported thereon via the inner wall 104 , and relative movement can occur between the guide 101 and the upper 3 . Alternatively, if the guide 101 is affixed directly to the upper and such relative movements do not occur.
- the boot 1 according to the first embodiment can become deformed so that the guide 101 slides with respect to the upper. It is seen hereinafter that this improves the tightening of the upper 3 and the retention of the foot.
- the guide 101 has an inner slot 114 , extending through the inner wall 104 , as well as an outer slot 115 , extending through the outer wall 105 .
- the two slots 114 , 115 are opposite one another, and extend along their lengths in a direction from one bridge 106 , 107 of the guide 101 to the other.
- the finger 103 is housed within the guide 101 , and it is maintained therein by any appropriate mechanism, while being perpendicular to the walls 104 , 105 .
- the finger 103 is made, for example, in the form of a pivot pin, i.e., a cylindrical element whose diameter can be within a range, for example, between two millimeters (mm) and twelve mm.
- the finger 103 extends through the slits 114 , 115 and the passage 108 to cooperate with the rack 62 , as is described further below.
- a biasing mechanism is provided for actuating the finger 103 .
- the biasing mechanism for the finger in a non-limiting manner, is here constituted by the movable lace guide/keeper/connection 34 .
- This connection 34 is affixed to the finger 103 by any appropriate expedient, such as by crimping, stamping, riveting, or the like. It is the mobility of the finger 103 with respect to the guide 101 that makes the connection 34 mobile, along a range that is determined by the length of the slots 114 , 115 . For example, the range can be between 10 mm and 25 mm.
- the operation of this device 50 is correlated with the operation of the first tightening device 30 .
- the boot 1 When the boot 1 is being used, for example during a walk, it is configured according to FIGS. 2 to 6 .
- the first tightening device 30 is tightened, which implies that the linkage 31 is tensioned. Consequently, the upper 3 is tightened and, in particular, the movable connection 34 is biased towards the upper bridge 107 , in a direction moving away from the sole 2 .
- the tensioning of the first tightening device 30 biases the movable connection 34 , and therefore the finger 103 , towards the rack 62 .
- the finger 103 is supported on the rack 62 , between two teeth 63 . This causes the length of the linkage 51 of the second tightening device 50 to remain constant.
- the rack 62 is then immobilized in the passage 108 . Consequently, the foot is held in the boot, not only in the area of the instep, but also in the area of the heel. For this reason, undesirable movement of the foot within the boot are very limited, or even completely prevented in certain cases.
- the foot Before or after use, the foot is inserted in or removed from the boot. To this end, the first tightening device 30 is loosened, which means that the linkage 31 is slackened, as is the case in FIGS. 7 and 8 . Consequently, the movable connection 34 and the finger 103 are no longer biased towards the rack 62 .
- the passage of the heel in the area of the second segment 61 causes a temporary lengthening of the linkage 51 , against the action of the elastic mechanism 53 , the elastic mechanism thereby conferring a variable length on the linkage 51 .
- the linkage 51 has its shortest length when the foot is removed from the boot.
- the positioning of the foot inside the boot provides it with a substantial length, as it causes a substantial lengthening, which occurs when the heel is in the area of the second segment 61 .
- the length of the linkage 51 then takes a nominal value, ranging between the shortest length and a substantial length, when the foot is in place in the boot.
- the tightening of the first tightening device 30 sets the nominal length of the linkage 51 during use of the boot 1 , as described above.
- the second device 50 is simultaneously in a locking state.
- the length of the linkage 51 is adjusted by the passage of the foot alone, i.e., without any additional manual action. In other words, the adjustment of the second tightening device 50 is automatic.
- the rack 62 can have a specific configuration. If a transverse direction Wo of the rack, oriented from one edge 67 , 68 to the other, is taken as a reference (see FIG. 7 , e.g.), each tooth 63 is dissymmetrical in a plane parallel to the surfaces 69 , 70 and with respect to an axis oriented along the direction Wo and extending through the apex 120 of a tooth 63 . Near the apex 120 , the surface of the tooth 63 turned toward the first end 65 forms, with the transverse direction Wo, an angle ⁇ ranging between 0° and 20°.
- the surface of the tooth 63 turned toward the second end 66 forms, with the transverse direction Wo, an angle ⁇ ranging between 20° and 70°.
- This configuration of the teeth 63 enables the rack 62 to push back the finger 103 when the first tightening device 30 is loosened and the linkage 51 of the second device 50 is biased in a lengthening direction.
- the pitch of the rack 62 is uniform along successive teeth. This pitch ranges between 2 mm and 12 mm; with values ranging from 5 mm to 8 mm being satisfactory.
- the movement of the finger 103 and of the movable connection 34 occurs along a direction that passes by the heel 4 and the instep, i.e., the separation between the lower portion 10 and the upper portion 11 of the upper 3 , in the area of the tightening first device 30 .
- the upper bridge 107 of the guide 101 is closer to the front 5 of the boot than the lower bridge 106 . This makes it easier to immobilize the rack 62 in the guide 101 with the finger 103 when the first tightening device 30 is tightened.
- the length of the linkage 51 is maintained by a positive connection, i.e., by an obstruction.
- the finger 103 is used to abut against a tooth 63 of the rack 62 . It is seen hereinafter that this can be implemented differently, using the second embodiment, for example, as shown in FIGS. 9 and 10 .
- the elements that are in common with the first embodiment are designated by the same reference numerals, including the guide 101 , the tab 102 and the locking finger 103 of a reversible immobilizing mechanism 54 .
- the first segment 130 of the inextensible portion 52 is comprised of a flexible band that is inextensible lengthwise but flexible widthwise and lengthwise. This means that when the first segment 130 is biased in a lengthening direction, the distance between its ends 135 , 136 remains constant. This also means that when the linkage 31 is tensioned, and the finger 103 is biased towards the upper bridge 107 , the width of the first segment 130 , measured between its edges (i.e., such edges being analogous to edges 67 , 68 of the first embodiment), is then locally reduced in the area of the finger 103 . In fact, the finger 103 compresses the first segment in the guide 101 .
- the first segment 130 includes one or more materials, such as synthetic fibers, woven or nonwoven, one or more layers of plastic material or leather, or any equivalent.
- the local deformation of the first segment 130 is reversible.
- the segment recovers its natural shape when the action of the finger 103 ceases. It is noted that in its active portion, the width of the first segment 130 is constant.
- the length of the linkage 51 is maintained by a connection by friction. Indeed, the action of the finger 103 increases the contact surface and the friction forces between the first segment 130 and the guide 101 , in the passage 108 .
- FIGS. 11 and 12 show a particular, non-limiting structure of the upper of the boot 1 according to the first embodiment, second embodiment, or any other alternative embodiment of the tightening devices 30 , 50 , which are not shown for reasons of graphic clarity. It should however be considered that their respective configurations and arrangements are matched with the structure of the upper 3 .
- the upper 3 therefore, comprises two inner flaps, i.e., a lateral flap 145 and a medial flap 146 .
- the flaps 145 , 146 extend beneath the first tightening device 30 , and partially overlap one another.
- the flaps slide with respect to one another, in particular when the upper 3 is being tightened by means of the first tightening device 30 . This increases the tightening force and, consequently, the foot is held more firmly.
- the structure of a rack can vary, in particular with regard to the shape or the arrangement of the teeth.
Abstract
Description
- This application claims priority under 35 U.S.C. §119 of French Patent Application No. 09 05054, filed on Oct. 21, 2009, the disclosure of which is hereby incorporated by reference thereto in its entirety.
- 1. Field of the Invention
- The invention relates to footwear, i.e., shoes or boots, including footwear for one or more sports, and more particularly to footwear intended for activities such as skiing, hiking, walking, and athletics, although not limited thereto.
- Footwear of this type can be used in fields such as cross-country or telemark skiing, walking or running on flat or mountainous terrain, hiking, snowboarding, snowshoeing, roller skating, skateboarding, cycling, ball-playing sports, and the like.
- 2. Background and Other Information
- A boot can include a low upper or a high upper, or even a mid-upper. A boot can also be relatively flexible or, on the contrary, more rigid. However, it is in any case desirable that the user's foot be adequately held within the boot. Indeed, a foot properly held in the upper allows for a better use of the boot.
- For example, with a flexible boot, as used for the practice of cross-country skiing, adequate foot retention facilitates the transmission of sensory information and the rolling movement of the foot. In particular, in the area of the instep, a device for tightening the upper is adapted to hold the foot of the user.
- Conventionally, a tightening device includes a linkage, such as a lace, on the one hand, and connections for the lace to the upper. These connections are defined as keepers, associated with lateral and medial portions or quarters of the upper. The lace follows a path that leads it alternatively from one quarter to the other. Thus, it suffices to draw on the lace in order to bring the quarters closer to one another and to tighten the upper. The lace is then blocked to maintain the tightening.
- A problem that a good tightening device should seek to overcome is holding the foot thoroughly inside the boot. In other words, undesirable movements of the foot in the boot should be avoided, in particular in the area of the heel.
- Indeed, when the foot moves in the upper, in the area of the heel or elsewhere, the transmission of sensory information or steering impulses is less precise, thereby altering performances, in particular in sports.
- Moreover, repeated movements of the foot in the upper result in friction that cause injuries.
- In order to improve foot retention in the upper, known tightening devices have sought to increase tightening efficiency. For this reason, in particular, the sliding movement of the laces in the keepers is reduced, which enables them to be tensioned more easily. As a result, the foot is held more firmly in the area of the instep and/or metatarsus. This means that the foot is biased towards the sole with greater force.
- However it has been noted, in spite of the improved tightening efficiency, that the foot sometimes is not held thoroughly, and it is especially in the area of the heel that most undesirable movements of the foot in the upper are observed. Therefore, one way to improve foot retention has involved adding a structure for tightening the heel.
- For example, it is known from the
document FR 2 499 834 to encircle the heel of a boot closely with a linkage that is adjustably tensioned by the user. In this case, the boot includes a tightening device, as mentioned above, on the one hand, and a structure for tightening the heel. Nevertheless, it has been noted once again that the foot sometimes is not held thoroughly. - It has also been noted that a boot according to the prior art does not always provide sufficient comfort of use, or that it is not easy to handle, particularly with respect to actuating the tightening devices and mechanisms.
- It has also been noted that it is not always very convenient to put on or take off the boot.
- In view of the above, the invention includes a structure that improves foot retention in an article of footwear, such as a boot or, in other words, to reduce, or even to eliminate, undesirable displacements of the foot within the article of footwear or boot.
- In addition, the invention provides the boot with greater comfort, in static mode as well as in dynamic mode. It is indeed advantageous for the user to have a pleasant sensation, whether while standing still or while moving, such as, for example, during cross-country skiing or walking, or while engaged in similar activities. It is also advantageous to be able to easily handle the elements that activate or de-activate the tightening of the upper.
- Still further, an article of footwear according to the invention includes structure and arrangement that improves the fitting and/or removal of the article of footwear relative to the foot, in the sense that it is desirable to enable the foot to be inserted in or removed from the upper of the article of footwear more easily.
- To this end, the invention includes an article of footwear that includes a sole and an upper, the boot extending lengthwise from a rear end to a front end, widthwise between a lateral portion and a medial portion, and heightwise from the sole up to an upper end, the article of footwear of the invention having an opening for foot insertion, and including a first tightening device for tightening the lateral and medial portions, as well as a second tightening device for tightening a rear portion.
- An article of footwear according to the invention also includes a second tightening device that includes a linkage, such as a lace or filiform element, the linkage including a first inextensible portion and an elastic mechanism, the first inextensible portion extending along the rear portion, as well as along at least one of the lateral and medial portions, the elastic mechanism biasing the first inextensible portion in a direction reducing the length of the linkage, the article of footwear further including a reversible immobilization mechanism to immobilize the inextensible portion with respect to the upper.
- The second tightening device is structured and arranged to tighten the heel of the foot prior to tightening the upper. This involves wedging the heel before tightening the first tightening device. The wedging reduces or even eliminates the clearances between the foot heel and the upper, or between the foot heel and the linkage of the second tightening device. As a result, there are limited or no undesirable movements of the heel of the foot in the upper once tightening has been carried out. A resulting advantage is that the foot is held more efficiently in the upper, in the sense that undesirable movements of the foot with respect to the upper are markedly reduced, or even eliminated, in particular in the area of the heel. In other words, foot retention is more precise.
- According to an additional advantage, an article of footwear according to the invention is more comfortable, whether in static mode or in dynamic mode. This results in particular from a better connection of the foot to the upper. Moreover, the action of the elastic mechanism of the second tightening device, improves comfort in handling the elements that activate or inactivate the tightening of the upper. Such improvement results from reducing the operations for managing the tightening, as the elastic mechanism manages part of the tightening.
- Another advantage of the invention is to enable the foot to be inserted in or removed from the upper more easily. Indeed, such greater ease is made possible by the elastic mechanism.
- Other characteristics and advantages of the invention will be better understood from the description which follows, with reference to the annexed drawings illustrating, by way of nonlimiting embodiments, how the invention can be implemented, and in which:
-
FIG. 1 is a perspective front view of a boot according to a first embodiment of the invention; -

FIG. 11 is similar toFIG. 3 , according to a third embodiment of the invention; -
FIG. 12 is a cross-section along the line XII-XII ofFIG. 11 . - The first embodiment, which is described hereinafter, relates more particularly to boots adapted for cross-country or telemark skiing. However, the invention applies to other fields, such as those mentioned hereinabove. The term “boot” is used herein for convenience and the invention is not to be considered limiting by such use. Indeed, the invention encompasses boots, shoes, and other articles of footwear, whether such footwear have low uppers (for which the top of the upper extends beneath the ankle), high uppers (for which the top of the upper extends above the ankle), or mid-uppers (for which the top of the upper extends at the ankle).
- The first embodiment is described hereinafter with reference to
FIGS. 1 to 8 . - As shown in
FIG. 1 , a cross-country ski boot is adapted to receive the foot of the user or wearer. - In a known arrangement, the boot 1 includes a walking sole 2, i.e., an external sole, and an upper 3. The boot 1 extends lengthwise from a rear end, or
heel 4, to a front end, ortip 5; and widthwise between alateral side 6 and amedial side 7. - As shown, the upper 3 includes a
lower portion 10, adapted to surround the foot, as well as anupper portion 11, adapted to surround, i.e., cover, the ankle. However, consistent with the description above, an upper including only thelower portion 10 is within the scope of the invention. - According to the first illustrated embodiment, the boot 1 extends heightwise from the sole 2 to an
upper end 12, i.e., up to the free end of theupper portion 11 or of the upper 3. - As shown in
FIG. 2 , the boot 1 includes alateral portion 15, amedial portion 16, as well as arear portion 17. The boot 1 here includes anenvelope 18, which surrounds the ankle and covers the wear's foot while extending in the area of theportions envelope 18 demarcates anopening 19, in the area of theupper end 12, adapted to allow the foot therethrough and also to surround the ankle after the foot has been inserted within the boot. Theenvelope 18 is continuous along theopening 19. - In a non-limiting arrangement, the
envelope 18 is partially or entirely elastically deformable. For example, theenvelope 18 can be comprised of an elastic fabric. As a result, the perimeter of the opening is variable, and, for example, it can increase reversibly at the time the user's foot is passing through. This makes it possible to put on or take off the boot, but it also enables the envelope to closely fit the lower leg. A resulting advantage is increased resistance to the penetration of foreign objects in the upper. In particular, undesirable penetration of snow is avoided. - Therefore, the upper 3 is structured to enable a good flexion of the leg or a good rolling movement of the foot, as well as the transmission of sensory information or steering impulses. The sole can be relatively rigid, for example for practicing skating steps, or more flexible, for example for practicing alternative steps to thereby be structured to practice the two popular techniques known in the art.
- The
portions - Similarly, the structure of the upper described for the first embodiment of the invention is not limiting. For example, the
opening 19, instead of extending strictly in the area of theupper end 12, could be provided to extend between theportions front end 5. In this case, the boot can include a tongue between theportions - In addition, and without it being mandatory, the boot 1 includes a
flap 25 structured and arranged to reversibly cover thelower portion 10. Theflap 25 extends from oneportion - According to the first embodiment, the
flap 25 is affixed to themedial portion 16. Areversible closure 26 makes it possible to also affix theflap 25 to thelateral portion 15. For example, thereversible closure 26 includes a zipper or other slide fastener. However, any other structure could be provided to make the closure, such as a series of snap fasteners, for example. - The boot 1 further includes a
first tightening device 30, adapted to reversibly tighten the upper 3. More specifically, the tighteningdevice 30 tightens thelateral portion 15 andmedial portion 16. According to the first embodiment, thefirst tightening device 30 tightens theenvelope 18. - As seen in particular in
FIGS. 3 and 4 , the tighteningdevice 30 includes alinkage 31. This linkage is divided into afirst strand 32 and asecond strand 33, which are co-extensive, i.e., they are formed from a single linkage. The tighteningdevice 30 further includesconnections 34 to 41 (which can also be referred to as keepers or guides) for thestrands linkage 31, to the upper. For example, in a non-limiting arrangement, thedevice 30 includes fourlateral connections 34 to 37, as well as fourmedial connections 38 to 41. It is noted hereinafter that if most of theconnections 34 to 41 are immobile with respect to the upper 3, one 34 of them is mobile. Thelinkage 31 passes between the connections in order to bias them reversibly in a direction tightening the upper 3. To maintain the tightening, thedevice 30 includes ablocking mechanism 42, not described here as it is well-known to the one with ordinary skill in the art. According to the first embodiment, theblocking mechanism 42 acts on the twostrands linkage 31. For example, although merely a knot could tied with the two strands, a blocking device could be used, such as disclosed in U.S. Pat. No. 5,477,593, the disclosure of which is hereby incorporated by reference thereto in its entirety. - For a practical implementation of the tightening
device 30, thelinkage 31 can take the form of a lace, a string, or other filiform element, and theconnections 34 to 41 can be comprised of hooks or keepers, such as open guides, as shown. All of theconnections 34 to 41 are sliding connections, which promote a balancing of the tightening tensions. The tightening device of this practical implementation, however, is not considered to limit the invention. - The tightening
device 30 can be regarded as a first tightening device. The boot 1 also includes asecond tightening device 50. - According to the invention, the
second tightening device 50 includes alinkage 51, thelinkage 51 including a firstinextensible portion 52 and anelastic mechanism 53, the firstinextensible portion 52 extending along therear portion 17 of the boot 1, as well as along at least one of thelateral portion 15 and themedial portion 16, theelastic mechanism 53 biasing the firstinextensible portion 52 in a direction reducing the length of thelinkage 51, the boot 1 further including areversible immobilization mechanism 54 for immobilizing theinextensible portion 52, at least lengthwise, with respect to the upper 3. Theelastic mechanism 53 biases thelinkage 51 in a direction tightening the heel of the wearer, either directly, or via the upper 3. According to the first embodiment, as will become more readily apparent hereinafter, thelinkage 51 closely encircles the elasticallydeformable envelope 18 of the boot in the area of the lateral 15, rear 17, and medial 16 portions. In fact, the firstinextensible portion 52 extends along thelateral portion 15,rear portion 17 andmedial portion 16. This limits, or even avoids, movement of the heel of the foot heel in the upper. Consequently, the undesirable movements of the foot in the upper are markedly or even completely avoided. Foot retention is more precise, which allows a more precise transmission of support forces and sensory information. - The
linkage 51 of thesecond tightening device 50 is structured accordingly. According to the first embodiment of the invention, theinextensible portion 52 includes afirst segment 60, or immobilization segment, as well as asecond segment 61, or constriction segment. Eachsegment inextensible portion 52. - The
first segment 60 includes arack 62, i.e., an element which includes a series ofteeth 63 and recesses 64. Therack 62 has a length extending from afirst end 65 and asecond end 66, a width extending from afirst edge 67 to asecond edge 68, and a thickness extending from aninner surface 69 to anouter surface 70, theinner surface 69 facing the upper 3. In fact, therack 62 is a band, which is lengthwise inextensible although sufficiently flexible to bend, as shown in the drawing, along a transverse axis Wo (seeFIG. 7 , e.g.). A transverse axis extends from thefirst edge 67 to thesecond edge 68 edge. Its flexibility enables therack 62, and therefore thefirst segment 60, to closely follow the curvature of the upper 3. Thefirst segment 60, i.e., therack 62, for example, is made from a plastic material, such as polyethylene, polyamide, polyurethane, or any equivalent. - In a non-limiting manner, the
teeth 63 are directed so as to project in the area of an edge, for example thefirst edge 67. Consequently, therecesses 64 extend through therack 62, i.e., thefirst segment 60, from theinner surface 69 to theouter surface 70. - The
second segment 61 includes, for example, astrap 74 that extends lengthwise between afirst end 75 and asecond end 76, widthwise between a first edge 77 and a second edge 78, and depthwise between aninner surface 79 and anouter surface 80. Here again, theinner surface 79 is turned towards the upper 3. Thestrap 74 is inextensible lengthwise and flexible along a transverse axis. Such an axis extends from the first edge 77 to the second 78 edge. The flexibility of thestrap 74 enables it to closely follow the curvature of the upper 3. Thesecond segment 61, i.e., thestrap 74, for example, is made with fibers impregnated within a plastic material, woven or nonwoven fibers, or a band of synthetic material. - The
first segment 60 andsecond segment 61 prolong one another so as to extend around theheel 4. In fact, thesecond end 66 of therack 62 is affixed to thefirst end 75 of thestrap 74 by an attachment medium or element, such as an adhesive, stitching, or any equivalent. Thesecond end 76 of thesecond segment 61 is affixed to the upper 3, on themedial side 7, on theenvelope 18. Thesecond end 76 is affixed by any means, such as stitching, an adhesive, or any equivalent. Theend 76 is therefore permanently affixed to the upper 3, i.e., to theenvelope 18, in this case. Alternatively, theend 76 could be made removable from the upper. - In any case, as a result from the construction described hereinabove, the
inextensible portion 52 of thelinkage 51, with the exception of theend 76, can slide with respect to the upper 3, outside of the upper. Theinextensible portion 52 is tensionally biased by theelastic mechanism 53, as explained hereinafter. - In a non-limiting manner, the elastic mechanism in this case includes an
elastic band 84 that extends lengthwise from afirst end 85 to asecond end 86, widthwise between afirst edge 87 and asecond edge 88, and depthwise between aninner surface 89 and anouter surface 90. Here again, theinner surface 89 is turned towards the upper 3. Theband 84 is reversibly extensible, at least lengthwise. Theband 84 is in fact made of an elastically extensible fabric including rubber threads, for example, or equivalent materials. Thefirst end 85 of theband 84 is removably and adjustably affixed to the upper 3, by anattachment mechanism 91 that includes, for example, afabric portion 92 connected to theband 84 and afabric portion 93 connected to the upper. These portions are being merely referenced, inasmuch as they are well-known to one with ordinary skill in the art. For example, one of the two can take the form of loops and the other of the two can take the form of hooks, the loops and hooks being reversibly engageable for selective retention therebetween, such as known, e.g., as Velcro® brand hook and loop fasteners. It is therefore possible to arrange the first end 85 a little closer to thefront end 5 or a little closer to therear end 4 with respect to a referential position. The tension in thelinkage 51 can thereby be selectively adjustable. - It is to be understood that the
second end 86 of theband 84 is affixed to thefirst end 65 of therack 62. Here again, the attachment is made by any appropriate arrangement for such purpose, such as by stitching, an adhesive, or the like. This is, for example, and for practical purposes, a permanent, non-removable attachment. On the other hand, the invention encompasses an attachment that is intended to be temporary, i.e., one that is removable with or without a tool. - Finally, the
linkage 51 extends from thefirst end 85 of theelastic mechanism 53, or theband 84, to thesecond end 76 of thesecond segment 61, or thestrap 74. - The ends 85, 76 of the
linkage 51 are in asymmetrical and transverse arrangement. Indeed, thefirst end 85 of theband 84 is located in the front half of the boot 1, for example in the area of the metatarsus and halfway between the sole 2 and thecrest 98 thereabove. Thecrest 98 is the line that demarcates the limit between thelateral portion 15 and themedial portion 16. Thesecond end 76 is located in the rear half of the boot 1, for example in the area of the ankle. Thesecond end 76 is further away from the sole 2 than thefirst end 85. For this reason, thelinkage 51 extends in a tightening plane T inclined with respect to a plane S related to the sole 2, according to a particular angle α (seeFIG. 4 ). The plane S is that which extends along the sole 2, when the sole has its natural unstressed shape. The angle α ranges between 10° and 50°; values ranging from 20° to 35° yield good results. This means that the heel of the foot is efficiently retained against the sole 2 by means of thelinkage 51. The retention is effective as soon as thereversible immobilization mechanism 54 is actuated, as described below. - According to the first embodiment described with reference to
FIGS. 3 to 8 , theimmobilization mechanism 54 includes aguide 101, atab 102, and a lockingfinger 103. - The
guide 101 is adapted to guide the position and movement of theinextensible portion 52, in this case thefirst segment 60. To this end, theguide 101 includes aninner wall 104, opposite the upper 3, as well as anouter wall 105, which is opposite thereto. Theinner wall 104 andouter wall 105 are connected to one another by alower bridge 106 and anupper bridge 107. Thelower bridge 106 is referred to as such because it is closer to the sole 2 than theupper bridge 107. Thewalls bridges passage 108, through which thefirst segment 60 extends. In a non-limiting manner, thepassage 108 has a rectangular cross section; but it could be oblong, oval, or have any other shape. In the following description, the manner by which thesegment 60 slides within thepassage 108 of theguide 101 will be further explained. In a non-limiting manner, theguide 101 is located on thelateral portion 15, between the sole 2 and theopening 19. Alternatively, theguide 101 could be located on themedial portion 16. - The
tab 102 extends from a connectingend 109 to afastening end 110. The connectingend 109 is affixed to theguide 101, whereas thefastening end 110 is affixed to a portion of the upper 3 adjacent, for example, the sole 2. Alternatively, thetab 102 can be omitted. In that case, theguide 101 is directly affixed to the upper 3, i.e., to theenvelope 18, such attachment being accomplished by any appropriate expedient, such as an adhesive or stitching, or the like. - In a non-limiting manner, the
guide 101 and thetab 102 form a unitary element made, for example, out of a plastic material. The attachment of thefastening end 110, and therefore of theimmobilization mechanism 54, to the upper 3 is accomplished using an adhesive, stitching, or any equivalent. Thetab 102 is therefore permanently connected to the upper 3, which implies that theimmobilization mechanism 54 is non-removably mounted to the boot 1. Theguide 101 comes in contact with the upper 3 by being supported thereon via theinner wall 104, and relative movement can occur between theguide 101 and the upper 3. Alternatively, if theguide 101 is affixed directly to the upper and such relative movements do not occur. - In fact, during use, the boot 1 according to the first embodiment can become deformed so that the
guide 101 slides with respect to the upper. It is seen hereinafter that this improves the tightening of the upper 3 and the retention of the foot. - In order to receive the
finger 103, theguide 101 has aninner slot 114, extending through theinner wall 104, as well as anouter slot 115, extending through theouter wall 105. The twoslots bridge guide 101 to the other. Thefinger 103 is housed within theguide 101, and it is maintained therein by any appropriate mechanism, while being perpendicular to thewalls finger 103 is made, for example, in the form of a pivot pin, i.e., a cylindrical element whose diameter can be within a range, for example, between two millimeters (mm) and twelve mm. Thefinger 103 extends through theslits passage 108 to cooperate with therack 62, as is described further below. - A biasing mechanism is provided for actuating the
finger 103. In fact, the biasing mechanism for the finger, in a non-limiting manner, is here constituted by the movable lace guide/keeper/connection 34. Thisconnection 34 is affixed to thefinger 103 by any appropriate expedient, such as by crimping, stamping, riveting, or the like. It is the mobility of thefinger 103 with respect to theguide 101 that makes theconnection 34 mobile, along a range that is determined by the length of theslots - The function of the
second tightening device 50 will now be explained. In fact, the operation of thisdevice 50 is correlated with the operation of thefirst tightening device 30. This means in particular that when biased in a tightening direction, thefirst tightening device 30 causes thesecond tightening device 50 to be maintained in a given tightening and stable state. In other words, thissecond tightening device 50 cannot switch to another state as long as thefirst device 30 is not loosened. - When the boot 1 is being used, for example during a walk, it is configured according to
FIGS. 2 to 6 . In this case, thefirst tightening device 30 is tightened, which implies that thelinkage 31 is tensioned. Consequently, the upper 3 is tightened and, in particular, themovable connection 34 is biased towards theupper bridge 107, in a direction moving away from the sole 2. In fact, the tensioning of thefirst tightening device 30 biases themovable connection 34, and therefore thefinger 103, towards therack 62. As a result, thefinger 103 is supported on therack 62, between twoteeth 63. This causes the length of thelinkage 51 of thesecond tightening device 50 to remain constant. Indeed, therack 62 is then immobilized in thepassage 108. Consequently, the foot is held in the boot, not only in the area of the instep, but also in the area of the heel. For this reason, undesirable movement of the foot within the boot are very limited, or even completely prevented in certain cases. - Before or after use, the foot is inserted in or removed from the boot. To this end, the
first tightening device 30 is loosened, which means that thelinkage 31 is slackened, as is the case inFIGS. 7 and 8 . Consequently, themovable connection 34 and thefinger 103 are no longer biased towards therack 62. When the foot is inserted into or removed from the boot, the passage of the heel in the area of thesecond segment 61 causes a temporary lengthening of thelinkage 51, against the action of theelastic mechanism 53, the elastic mechanism thereby conferring a variable length on thelinkage 51. While thelinkage 51 is lengthening, atooth 63 pushes thefinger 103 towards thelower bridge 106, i.e., towards the sole 2 as well. The lengthening of thelinkage 51 causes therack 62 to move thefinger 103 away from theteeth 63. It is seen hereinafter that the configuration of the constituent elements of thesecond tightening device 50 promote, or facilitate, this process. - The
linkage 51 has its shortest length when the foot is removed from the boot. The positioning of the foot inside the boot provides it with a substantial length, as it causes a substantial lengthening, which occurs when the heel is in the area of thesecond segment 61. The length of thelinkage 51 then takes a nominal value, ranging between the shortest length and a substantial length, when the foot is in place in the boot. The tightening of thefirst tightening device 30 then sets the nominal length of thelinkage 51 during use of the boot 1, as described above. Thesecond device 50 is simultaneously in a locking state. The length of thelinkage 51 is adjusted by the passage of the foot alone, i.e., without any additional manual action. In other words, the adjustment of thesecond tightening device 50 is automatic. - In order to optimize the operation, or function, of the
second tightening device 50, therack 62 can have a specific configuration. If a transverse direction Wo of the rack, oriented from oneedge FIG. 7 , e.g.), eachtooth 63 is dissymmetrical in a plane parallel to thesurfaces tooth 63. Near the apex 120, the surface of thetooth 63 turned toward thefirst end 65 forms, with the transverse direction Wo, an angle β ranging between 0° and 20°. Still near the apex 120, the surface of thetooth 63 turned toward thesecond end 66 forms, with the transverse direction Wo, an angle γ ranging between 20° and 70°. This configuration of theteeth 63 enables therack 62 to push back thefinger 103 when thefirst tightening device 30 is loosened and thelinkage 51 of thesecond device 50 is biased in a lengthening direction. - In addition, without it being mandatory, the pitch of the
rack 62 is uniform along successive teeth. This pitch ranges between 2 mm and 12 mm; with values ranging from 5 mm to 8 mm being satisfactory. - It is also noted that the movement of the
finger 103 and of themovable connection 34 occurs along a direction that passes by theheel 4 and the instep, i.e., the separation between thelower portion 10 and theupper portion 11 of the upper 3, in the area of the tighteningfirst device 30. In other words, theupper bridge 107 of theguide 101 is closer to thefront 5 of the boot than thelower bridge 106. This makes it easier to immobilize therack 62 in theguide 101 with thefinger 103 when thefirst tightening device 30 is tightened. - In the structure described above, the length of the
linkage 51 is maintained by a positive connection, i.e., by an obstruction. Indeed, thefinger 103 is used to abut against atooth 63 of therack 62. It is seen hereinafter that this can be implemented differently, using the second embodiment, for example, as shown inFIGS. 9 and 10 . - For simplification, the elements that are in common with the first embodiment are designated by the same reference numerals, including the
guide 101, thetab 102 and the lockingfinger 103 of areversible immobilizing mechanism 54. - What is specific to the second embodiment lies in the fact that the
first segment 130 of theinextensible portion 52 is comprised of a flexible band that is inextensible lengthwise but flexible widthwise and lengthwise. This means that when thefirst segment 130 is biased in a lengthening direction, the distance between itsends linkage 31 is tensioned, and thefinger 103 is biased towards theupper bridge 107, the width of thefirst segment 130, measured between its edges (i.e., such edges being analogous toedges finger 103. In fact, thefinger 103 compresses the first segment in theguide 101. To make this operation possible, thefirst segment 130 includes one or more materials, such as synthetic fibers, woven or nonwoven, one or more layers of plastic material or leather, or any equivalent. The local deformation of thefirst segment 130 is reversible. The segment recovers its natural shape when the action of thefinger 103 ceases. It is noted that in its active portion, the width of thefirst segment 130 is constant. According to the second embodiment, the length of thelinkage 51 is maintained by a connection by friction. Indeed, the action of thefinger 103 increases the contact surface and the friction forces between thefirst segment 130 and theguide 101, in thepassage 108. - The third embodiment is now described with reference to
FIGS. 11 and 12 . Here again, the elements in common with the first embodiment are designated by the same reference numerals. In fact,FIGS. 11 and 12 show a particular, non-limiting structure of the upper of the boot 1 according to the first embodiment, second embodiment, or any other alternative embodiment of thetightening devices - The upper 3, therefore, comprises two inner flaps, i.e., a
lateral flap 145 and amedial flap 146. Theflaps first tightening device 30, and partially overlap one another. The flaps slide with respect to one another, in particular when the upper 3 is being tightened by means of thefirst tightening device 30. This increases the tightening force and, consequently, the foot is held more firmly. - In any case, the invention is implemented using materials and techniques of implementation known to one of ordinary skill in the art.
- The invention is not limited to the embodiments and particular details described hereinabove, and includes all technical equivalents that fall within the scope of the claims that follow.
- In particular, numerous alternative structures can be provided for the tightening devices. For example, the structure of a rack can vary, in particular with regard to the shape or the arrangement of the teeth.
- In addition, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.
