Definitions
- the present invention relates to a sports shoe, in particular for walking, running or jumping.
- Existing sports shoes can be painful for the user when they are used more or less intensively, and even generate phlyctenes, inflammations, bruises or other pathologies in specific places of the foot, know at the level of the internal face and in front part of the heel, at the level of the first and fifth metatarsal heads and at the level of the end of the toes.
- Shoes comprising these soles have the drawbacks of being difficult to manufacture, not very comfortable and of ensuring only limited protection of the foot, due to these camber and lateral recesses.
- a sole having lateral recesses and comprising a stiffening element disposed along the longitudinal axis of the sole, these recesses allowing the sole to be twisted along its longitudinal axis, that is to say the pivoting of the front part thereof relative to its rear part around this axis, while the stiffening element while allowing this torsion, limits the bending of the sole around a horizontal transverse axis and prevents the pivoting of the front part thereof relative to its rear part around a vertical axis.
- Shoes fitted with such soles also prove not to respond perfectly to the anatomical evolution of the foot during sports activities and may present wear and assembly problems at the points of attachment of the stiffening element to the sole.
- the present invention aims to remedy these drawbacks by providing a sports shoe providing perfect foot comfort in all circumstances, and especially when the user is in motion, this shoe must, in addition, have perfect resistance to wear.
- the stiffening element is shaped so as to impart relative rigidity to the sole along a transverse horizontal axis, that is to say in front-rear bending of the sole, and around of the longitudinal axis thereof, that is to say in torsion of its front part relative to its rear part, while allowing the pivoting of its front part relative to its rear part about an axis vertical located substantially at the calcaneo-cuboid joint of the foot.
- the side walls of the upper of the shoe have relative flexibility in a horizontal plane, substantially at the level of said articulation.
- this phenomenon seems to have the role, on the one hand, by tending the plantar fascia, to stiffen the bony arch of the foot, which makes it possible to avoid its crushing and to absorb the shock of the foot against the ground. , and, on the other hand, to orient the plantar fascia so that the heel is placed substantially in the axis of the stroke, which makes it possible to optimize the grip and the transmission of the impulse.
- the shoe according to the invention thanks to its possibility of pivoting, can adapt to deformation foot clean for each user and provides perfect comfort with moderate wear, even under heavy use.
- the sole comprises two grooves arranged longitudinally on either side of the stiffening element, giving it flexibility in a horizontal plane necessary for the aforementioned pivoting, that is to say allowing the compression of its constituent material of the side towards which its front and rear parts pivot and the stretch of its constituent material on the opposite side, and this while retaining material along the lateral edges of the sole to provide support and protection for the foot at this location.
- the grooves are arranged in the upper face of the sole while the stiffening element is housed in a cavity provided in the lower part of the sole.
- the grooves have a curved shape to one • within the sole and sides of the sole which delimit the outwardly comprises a plurality of notches arranged substantially perpendicular to them.
- the stiffening element is contained in a housing made of relatively flexible material, the central part of which, centered on the pivot axis, is narrowed and shaped to have a certain elastic flexibility in a horizontal plane, in order to be able to follow the pivoting of the front and rear parts of the sole around said axis, and the end parts of which are flared and have rigid side walls which the walls meet lateral of the stiffening element during pivoting of the front and rear parts of the sole, these lateral walls playing the role of limit stops for pivoting of said front and rear parts of the sole.
- the housing is advantageously shaped so that its side walls allow the front and rear parts of the sole to pivot by substantially 15 ° on either side of the longitudinal axis of the sole.
- the housing allows, in addition to constituting these stops, to protect the stiffening element, and participates in the elastic return of the front and rear parts of the sole as well as in the stiffening of the latter in bending and in torsion.
- the end walls of the housing have a concave shape of constant curvature substantially centered on the pivot axis of the front and rear parts of the sole, and the stiffening element has convex end walls with the same radius of curvature as the end walls of the housing, along which they slide when the front and rear parts of the sole pivot.
- the housing cover has two longitudinal wings capable of being engaged in complementary recesses arranged in the underside of the sole and of being covered by wear pads. In this way, the bonding surfaces are large, which allows good strength of the assembly.
- the crampons of the sole wear pads are arranged in lines more or less concentric with the pivot axis of the front and rear parts of the sole, so that they have always edges substantially perpendicular to the axis of the step or the race, whatever the amplitude of the pivoting of the front and rear parts of the sole.
- Figure 1 is a perspective view
- Figure 2 is an exploded perspective view in partial longitudinal section
- Figure 3 is a bottom view with partial cutaway
- Figure 4 is a sectional view along the line IV-IV of Figure 3
- Figure 5 is a sectional view along the line V-V of Figure 4
- Figure 6 is a view similar to Figure 3, in a particular operating position.
- the figures represent, from different angles, a sport shoe 1, in particular walking, running or jumping.
- This shoe comprises two longitudinal grooves 2 arranged from the upper face of the sole 3 and a cavity 4 arranged in the lower face of the sole 3, between the grooves 2.
- This cavity 4 receives a housing 5 which contains an element 6 of stiffening of the sole 3.
- the grooves 2 are located along the lateral edges of the sole 3. They are substantially centered on the axis of the calcaneo-cuboid joint of the foot and have a generally curved shape towards the interior of the sole 3.
- the walls of the latter, which externally delimit the grooves 2, comprise a plurality of notches 7 arranged substantially perpendicular to them.
- the cavity 4 is also substantially centered on the axis of the calcaneo-cuboid joint and has a narrowed shape in the central part and flared at its ends, the lateral edges of which more or less follow the walls of the sole 3 which internally delimit the grooves 2.
- the walls of the sole 3 delimiting the ends of the cavity 4 have a concave shape of constant curvature, substantially centered on the axis of the calcaneo-cuboid joint.
- the cavity 4 is further extended by two recesses 10 of less depth than it.
- the housing 5 consists of a bottom 11 and a cover 12 of relatively flexible plastic material, in which the bottom 11 can be fitted, this cover 12 having two longitudinal ears 13, of shape corresponding to that of recesses 10.
- the bottom 11 and the cover 12 have a shape which corresponds to that of the cavity 4, in which they can be inserted without play, the ears 13 of the cover 12 being positioned in the recesses 10.
- the bottom 11 of the housing 5 has a wall 15, disposed on its longitudinal median axis and projecting towards the interior of the housing 5.
- the stiffening element 6 is made of rigid plastic and has a general shape which corresponds to that of the housing 5, except that the angle formed by the rectilinear side walls 6a of each of its flared ends is less than about 15 ° at the angle formed by the corresponding side walls 11a of the ends of the bottom 11, so that each aforementioned side wall 6a of the element stiffening 6 defines, with the corresponding side wall 11a facing it, a space 20 in the form of a sector of a circle with an angle of approximately 7.5 °.
- the stiffening element 6 has a notch 21 which engages around said projecting wall 15 of the housing 5, the shape of this notch 21 being such that it delimits between the stiffening element 6 and the projecting wall. 15, two spaces 22 substantially in the form of a sector of a circle, each of which is at an angle of approximately 7.5 °.
- the side walls of the upper of the shoe have, moreover, side inserts 23 of extensible material, giving them relative flexibility in a horizontal plane, substantially at the level of said articulation.
- the shoe 1 may comprise a band 24 bearing under the midsole 3 at or near the pivoting zone and enclosing the instep, this band 24 being able to be stretched by the laces in order to clamp the shoe 1 and hold the sole 3 against the foot.
- the efficiency of shoe 1 is significantly increased thanks to this clamping.
- the stiffening element 6 is inserted into the housing 5, and the latter, after closing, is put in place in the cavity 4, the rubber wear pads 25 of the sole 3, the crampons 26 of which are arranged along more or less concentric lines with the axis of the aforementioned calcaneo-cuboid joint, covering the ears 13 to carry out the final assembly of the assembly.
- the latter gives relative rigidity to the sole 3 along a horizontal transverse axis, that is to say in front-rear bending of the sole 3, and around a longitudinal axis thereof, that is to say -tell in torsion of its front part with respect to its rear part, while allowing, in combination with the grooves 2, the pivoting of the front part of the sole 3 relative to its rear part about a vertical axis substantially coincident with the axis of the calcaneo-cuboid joint of the foot, as shown in FIG. 6.
- the grooves 2 allow, in effect, the compression of the constituent material of the sole on the side towards which the front and rear parts thereof pivot and the stretching of its constituent material on the opposite side, and this while retaining flexible material along the lateral edges of the sole 3 to provide support and protection for the foot at this location.
- the aforementioned spaces 20, 22 allow the housing 5 to follow the pivoting of the front and rear parts of the sole around the axis of the aforementioned articulation, the lateral walls 11a of the bottom 11 or of the projecting wall 15 playing the role limit stops for pivoting the front and rear parts by an amplitude of the order of 15 ° on either side of the longitudinal axis of the shoe 1.
- the housing 5 also makes it possible to protect the stiffening element 6, and participates in the elastic return of the front and rear parts of the sole 3, as well as in the stiffening of these in bending and in torsion.
- the shoe according to the invention thanks to its possibility of pivoting around the aforementioned axis, can adapt to the natural deformation of the foot during sports activities, while providing perfect comfort to the shoe at the level of the pivot axis, because the flexibility of the sole is obtained without making recesses in it limiting the protection of the foot.
- the sole 3 has a perfect visual appearance.
- the above-mentioned mounting of the stiffening element 6 in the sole 3 provides large bonding surfaces which eliminate any risk of wear, and in particular of shearing of the sole 3 at the level of the attachment of the element 6 to the latter, the housing 5 constituting an interface between the rigid material of the stiffening element 6 and that, flexible, of the sole 3.
- the sole could include a cavity housing a series of successive links articulated to each other in a horizontal plane in the manner of the vertebrae of a spinal column, but linked to each other. others rigidly in flexion in a vertical plane and in torsion, along the axis of the series, which would make it possible to provide the aforementioned rigidity along the aforementioned transverse and longitudinal axes and the possibility of pivoting of its front and rear parts in a horizontal plane.
