Claims. (Cl. 36--11.5)
This invention relates to articles of footwear compris ing a sole and foot retaining means thereon and more specially to footwear such as sandals or the like, although the invention is applicable to other kinds of footwear also.
Generally stated, the invention pertains to an article of footwear wherein the sole and insole are unitary, the edges of the sole being provided with recesses or pockets adapted to receive tongues extending from the upper or foot retaining means, such tongues being then connected to the sole. Preferably, all portions of the article of footwear, with the exception of the fastening means, are composed of a resilient, compliant, elastic material such as a resinous, thermoplastic or thermosetting composition, compounded rubber (natural or synthetic) or other suitable material.
An object of .the present invention is to disclose and provide a simple, effective and inexpensive article of footwear made from a minimum of parts of resilient, resinous, thermoplastic or thermosetting organic composition, the resiliency of the material and the self-adjusting construction resulting in a comfortable and lightweight article capable of conforming to a greater range of variations in foot width and foot contour (for a given size) than footwear constructed in the usual manner.
An object of this invention is to provide retaining or attaching means for .firmly connecting the upper or foot retaining portion to the sole.
Another object is to provide means which make it possible to attach the upper to the outsole in a simple and inexpensive manner.
A further object of this invention is to provideretaining or attaching means for connecting to the outsole an upper or foot retaining means including straps, the attaching means making it possible to obtain a firm connection of the straps'to the outsole and simultaneously permit pivotal movement or oscillation with respect to the outsole without damage to either the outsole or upper. The strap means and upper can in this manner adjust itself to the form of the foot of the wearer without undue strain.
A still further object of the invention is to provide articles of footwear wherein an upper is attached to an outsole, the ,attaching means being protected from wear and being maintained out of contact with the ground, the outsole being provided with integral wearing ribs which impart long life to the sole and prevent skidding.
A still further object of the invention is to provide a sole adapted for articles of footwear having means for connecting an upper thereto and integral spaced ribs on the .lowersurface, the ribs varying in height so as to permit ditferentportions of the top surface of the sole to lie in different planes when the faces of the ribs are in contact with a single plane or with the ground.
Other objects, uses and advantages of the invention will appear from the following description, reference being bad to the appended drawings in which:
Fig. 1 is a perspective view partly in section of a sandal made in accordance with the present invention.
Fig. 2is a perspective view of the front portion of the bottom of a sandal.
Fig. 3 is a vertical sectiontaken through a heel portion of the sandal along a plane parallel to the axis of such sandal.
Fig. 4 is a plan view of the bottom. of the integral outsole-insole of the shoe.
The sandal illustrated in the drawings is provided with an outsole generally indicated at 1, this outsole being made in one piece, as by molding from a plastic artificial substance such as an artificial resin, synthetic rubber, or the like. This outsole 1 is provided with a top surface 2 which constitutes the insole and a lower surface 3. This lower surface is provided with a plurality of spaced ribs integral with the sole, the ribs varying in height to permit different portions of the top surface 2 of the sole 1 to lie in different planes when the faces of the ribs are in contact with the ground. The lower surface 3 of the sole may, for example, be provided with a marginal rib 4, the heel portion 4 of such marginal rib being of greater height than at other portions of the sole so as to impart a higher elevation to the top surface of the sole in the region of the heel. A plurality of additional spaced ribs 5, G, 7 and the like are carried by the .lowersnrface of the sole and integral therewith, these ribs having downwardly directed faces capable of presenting wearing surfaces, imparting anti-slipping characteristics to the footwear and also providing locations or spaces for fastening means as will be described here after.
Horizontally disposed pockets or recesses are formed in the sole and extend inwardly from the side edges of the sole. Such recesses are indicated at S, 9 and 10 and extend inwardly beneath the upper surface 2 of the sole 1, each of said recesses opening outwardly. A portion of the sole between the recess and the top surface 2 may be cut away as indicated at 11, 12 and the like.
In the embodiment illustrated, the upper generally indicated at 13 comprises interwoven straps such as the straps 14, 15, 16, 17 and 18 which can be made from synthetic plastics, rubber compositions, or the like. Terminal portions of the transverse straps 14, 15 and 16 extend into appropriate pockets or recesses formed in the sole; for example, terminal portion 16 will extend into recess 9; the end portion of strap 18 extends into recess 10; strap portion 17 is provided with a heel part and downwardly extending portions adapted to extend into recess 8.
The top of each recess can be cut away as indicated at 11 or the tops and intervening walls between a series of recesses or pockets can be cut away as indicated at 12 so as to form a shoulder along the edge of the sole 1, such shoulder being flush with the bottoms of adjacent recesses such as 9, 9', etc. The width of the shouider is sufficient to accommodate the terminal portions or tongues of the straps 14-48; the width of the shoulder is preferably equal to or a little greater than the thick ness of the straps and prevents the straps from extending materially beyond the margins of the sole.
The top and bottom walls of each of the recesses such as thereeess 8 are provided with coaxial aligned apertures 20 and 21. The terminal portion or tongue of each of the straps may also be provided with an aperture such as, for example, the aperture 22 shown in the terminal portion of strap 16'. The entire upper (comprising the interwoven straps in the illustrated embodiment) is then attached to the unitary sole by inserting the terminal portions into corresponding recesses and applying suitable fastening means through the correlated apertures. Non mally, rivets are employed as fastening means and such rivets may be of any desired type, for example, headed rivets, semi-tubular rivets, full tubular rivets (with or without caps), bifurcated or split rivets (with or without caps) or compression rivets (combination of a solid and a deep drilled rivet).
At this time attention may be called tothe fact that the various ribs such as 5, 6, 7 and the like are so placed on the lower surface of the sole 1' as to leave suitable spaces between the ribs to receive the lower heads of the connecting rivets. The spacing of the ribs and placement of the rivets is best shown in Fig. 4 wherein it will be noted that the rivets 25, 26, 27, etc. engagethe lower surface 3 of the sole 1 between the marginal rib 4 and the other ribs.
It may also be noted that the terminal portions of the straps or tongues are slightly smaller than the recesses or pockets so that a certain amount of pivotal motion may take place and the tongues may pivot upon their rivets Within the recess thereby permitting the entire upper from which the tongues extend to move slightly and adjust itself to the form and contour of the wearers foot. Inasmuch as the lower ends or caps of the rivets are in a different plane than the wearing surfaces of the ribs 4, 5, 6, etc., the rivets are protected from direct contact with the ground and will not wear away.
It is to be noted that the spacing of the ribs on the lower surface of the sole not only provides zones in which the rivets or fastening devices can be placed but also imparts resilience to the top portion of the sole, the relatively thin sole between the ribs being capable of flexing and cushioning the weight of the wearer. It will be understood that the upper, relatively smooth surface 2 of the sole constitutes an insole which is an integral, irremovably associated part of the sole itself. When U-shaped or V-shaped ribs are employed, their edges offer good resistance against skidding both longitudinally and in a transverse direction.
Although a particular embodiment of the invention has been described, it will be apparent to those skilled in the art that numerous modifications and variations may be made. The upper may be constructed in any desired manner and be provided with tongues capable of extending into the preformed or molded recesses. Furthermore, it is not necessary to preform the holes or apertures such as 20, 22 and the like since certain types of fastening devices can be punched through the imperforate wall portions of the sole and tongue. All changes coming within the scope of the appended claims are embraced thereby.
