Abstract

The invention relates to a shoe sole for efficiently maintaining the other parts thereof therebetween, more particularly, the parts whose assembling by gluing or by other methods is difficult to carry out and, consequently causes premature breakage problems. The inventive sole consists of a part overlapping and/or superimposing the other sole parts in such a way that they are fixedly attached to each other. A specific shape of the inventive sole enables different sole parts, for example contact soles, to be assembled by the insertion thereof between L or U -shaped edges of said sole and the shoe insoles. The projected part or the inverted L -shaped edge of the parts supported by the inventive sole are fixedly and definitively inserted between the inventive sole surface the insole surface.

Description

Description Support Sole

[1] Field of the Invention

[2] The present invention relates to a shoe sole unit; more specifically a part whose function is to hold up other parts that have technical incompatibilities bonding or assembly.

[3] Context

[4] Every shoe consists of two distinctive parts: the upper and the sole.

While the rod covers the upper part of the foot and ensure the holding of the shoe, the sole has several functions, including protecting the foot against the rigors of soil.

[5] Different qualities are sought regarding the sole (lightness, flexibility, compressibility, adhesion, durability, holding, memory, etc.) and various materials respond more or less effectively at each of these desired qualities. Moreover, the costs of using these various materials vary.

[6] Therefore, a multitude of materials (rubbers, polyurethanes, EVA, PVC, thermoplastic polyurethanes, etc.), produced in various formulations and densities, are often combined to form a multi-piece sole. For example, the contact sole, which directly touches the ground, require optimum grip and requires other qualities such as resistance to abrasion, heat resistance, etc. The between-sole, which follows the underside of the foot, requires both lightness, flexibility, compression property, memory, etc. So there are significant advantages in combining various materials, various forms and densities to form a multi-piece outsole and consequently multiple functions.

[7] The component parts of these multi-piece flanges are joined together by bonding methods (chemically or by using an adhesive agent) or by other methods well documented in the field of the manufacture of footwear. For example, several soles are assembled by "curing" by "injection" or sewn using various techniques (Goodyear Weit, Opanka, Strobel, etc.) and many variations. These assembly methods should take into account compatibility of the various materials, formulations and densities of all parts forming the sole. Compounds of families close together easily associate while remote families of materials have assembly problems, resulting for designers and technical incompatibility of shoe manufacturers and / or user of premature failure after takeoff from parts which constitute the sole.

[8] Description of prior art [9] In recent years, designers and manufacturers of shoes worn by increasingly sophisticated techniques to create and produce shoes more durable, comfortable and safe.

[10] First, the appearance of double density soles injected it possible to separate the flanges in two parts with distinct functions: the inter-sole, both flexible and lightweight, provides the user with a rate high compression to absorb shocks. The contact sole, on the other hand, improves abrasion resistant - and therefore sustainability - of the shoe. The use of dual density soles, however, requires designers and manufacturers to compromise, regarding the sole contact between a very durable material and a release material. Indeed, it is well known that a more abrasion resistant material - and therefore more dense and hard - proves just as slippery. Regarding the inter-sole, the designers and manufacturers must choose between a lightweight material - but the compression ratio is not optimal - and heavier material - but so compression rate and memory are best. This is why the dual density soles were replaced soles triple and quadruple densities and multiple parts.

[11] Several patents have been filed for the manufacture of these shoes multi parts.

[12] The Canadian patent 2,153,082, for example, suggests the use of a three-way injection machine to produce successively three layers to each other, the second layer through the third layer to provide two different materials ground contact. This manufacturing method allows the use of a highly resistant material to abrasion for the third layer, while the second layer contributes to the adhesion of the sole. But this production method requires the use of chemically compatible materials as the first layer juxtaposed the second and the second juxtaposes the third. It is not possible, according to such a manufacturing method, to use a part - for example for the second layer - which is incompatible with the first or third layer. Moreover, it is not possible to use a material that is "injection" since said patent relates exclusively to the use of an injection machine.

[13] The Canadian patent 2,215,511 opens the way for the insertion of two separate parts through a contacting flange having one or more windows. The preferred embodiment shown in this patent includes two transparent windows through which the user can observe the damping parts. The contact sole includes a surface for support and supporting translucent windows. Now the object of the invention essentially relates to the idea that the user can observe the damping parts. Again, the parts constituting windows must be chemically compatible with the sole that the shoulder and in which they are glued. In this context, it is not possible to combine various materials, various densities and various forms of remote families in a multi-part outsole.

[14] The invention herein disclosed and claimed provides the use of a specifically designed part to retain and secure other parts of a sole (one or more pieces) with the midsole or part the closest to the upper of a boot. The present invention essentially differs from existing patents by its ability to assemble parts and / or materials having technical incompatibilities and, consequently, problems of bonding or assembly. In addition, the present invention is distinguished by its ability to assemble parts from various manufacturing processes - and therefore manufactured using various techniques and using various machines.

[15] Description of drawings

[16] Figure A shows a plan view of a shoe profile. One distinguishes the rod (1), typically formed of leather and / or textile materials, as well as the sole (2), composed here of two constituent parts: between the insole (3), also called "sole comfort ", and the contact sole (4), also called" surface sole. "

[17] Figure B is a partially exploded and broken away perspective view of a sole having three distinctive parts: the inter-sole (3), the contact base (4) and a preferred embodiment of a support flange (5) in which the invention is here disclosed and claimed. It is worth noting that, in the particular embodiment illustrated in figure B, the contact pad (4) consists of two separate pieces, one under the heel and the other under the sole of the foot. The configuration of the contact flange may however be realized with a multitude of ways. In the particular embodiment illustrated in figure B, the contact flange (4) located under the sole of the foot can be designed and manufactured in a material and / or completely different density (and according to different methods and procedures) of the contact sole (4) which is located under the heel, thus creating a sole four parts and distinct functions.

[18] Figure C is a schematic vertical section in the center of a shoe, from the front to the rear. One distinguishes the rod (1) and the sole (2), the latter being composed of the inter-sole (3), a contact pad (4) at the front and at the heel, as well as of a preferred embodiment of a support shoe (5). It is worth noting that the support sole (5) rigidly fixed to the front and rear parts of the contact pad (4) by trapping their protrusions (7) with its shaped "L". In the center, the support sole (5) overlaps the front and rear parts of the contact pad (4) by embedding in its shape in the "U". [19] Figure D shows a schematic section perpendicular to the figure C at the front of the shoe. One distinguishes between the insole (3), the contact base (4) and a preferred embodiment of the support sole (5). The form "L" of the latter overlaps the protruding portion (7) of the contact pad (4) and locks the latter between the support sole (5) and the between-sole (3). We also note that the common surfaces (6) between the support sole (5) and the between-sole (3) allow a convenient and strong assembly of these two parts.

[20] FIG I also shows a schematic section perpendicular to the figure

C, this time at the back of the shoe. There are substantially the same elements and the same configurations as in Figure D, either between the insole (3), the contact base (4) and a preferred embodiment of a support shoe (5). Just as in Figure D, the projecting flanges can be seen (7) of the contact pad (4), which support each other on each side of the part "L" of the support sole (5). Finally, the common surfaces (6) between the insole (3) and to the support sole (5) allow to fix solidly and permanently the contact sole (4). It is noteworthy that these common surfaces (6) are quite distinctive and unique to the present invention.

[21] Detailed Description of the Invention

[22] The invention aims to allow assembly sole portions from materials and / or forms and / or densities and / or alloys which, because of their nature or constitution, not s does not readily combine chemically and / or by various bonding methods and, consequently, cause various problems of technical incompatibility and / or premature breakage more take-off of said parts.

[23] The invention, called support sole (5) consists of a part whose purpose is to strengthen other parts of permanent way (4) with the inter-sole (3), or any other part of the sole may represent between-them some problems of technical incompatibility, bonding or assembly. The invention may also solidify parts directly with the stem or any part itself attached to the shaft, and no matter the method of assembly of this part to the rod.

[24] The novelty lies in the way solidify parts by trapping with the aid of the support sole (5) which, by its particular shape "L" (as distinguished in Figures C and D) or in "U", overlaps and / or superimposes the other parts (4) and holds them in place. These last elements (4) have a shape inverted "L" or a projecting rim (7) which support one of the support sole (5) and allowing the support sole (5) to hold them securely in place against between the sole (3) against the rod (1) or any other part connected thereto.

[25] Optionally, the support sole (5) can be manufactured in a material or alloy chemically and physically compatible with all other parts of the sole. This "cross-compatibility" has the advantage of increasing the strength of the link between the support sole (5) and third parties (3 and 4) incompatible Entre them.

[26] Still optionally, the support sole (5) is made of a material having excellent abrasion resistance and excellent bending rate, thereby contributing - in addition to its first connecting function - the durability of the sole and, consequently, the durability of the shoe.

[27] To enable a lasting joining of parts which exhibit incompatibilities with the rod (1) between the insole (3) or any other part associated with the stem (1) or between the insole (3) , the support sole (5) is to be assembled from solid and permanently to the shank (1) or between the insole (3) or any other part linked solid and permanently to the shank (1) or between-sole (3), whatever the assembly method used. A contact surface (6) between the strong and durable support sole (5) and the between-sole (3) - or rod or any other part associated to the stem or between midsole - appears as a capital and constitutive element of the present invention.

[28] In a preferred embodiment, a support sole (5) of thermoplastic polyurethane (TPU) will firmly secure the contact pads (4) of rubber with a between-sole (3) of polyurethane (PU). This has the advantage of combining, in a viable and functional sole, adhesion advantages and heat resistance of the rubber with the advantages of lightness, flexibility, compressibility and polyurethane memory. In addition, the support sole (5), in the preferred embodiment described herein, contributes to the improvement of the abrasion resistance by its constituent material.

[29] The invention is useful in several respects. It helps to design, create, manufacture and use durable and functional soles combining various pieces that offer different qualities: lightness, flexibility, adhesion, compressibility, memory, abrasion resistance, heat resistance, chemical resistance, etc.

[30] The invention proves new in that it allows to design, create, manufacture and use of soles whose parts are made of materials and / or formulas and / or densities and / or alloys not chemically compatible or not easily assembled together by gluing and / or other traditional assembly methods.

[31] The inventive contribution lies in the way so the support sole (5) in form of

"L" or "U" secures them separate parts (4) overlapping and / or superimposing and / or fitting them and / or by supporting their projecting flanges (7) while ensuring a strong and durable assembly through contact surfaces (6) between said support base (5) and either: the shaft (1) between the insole (3) or any other part linked solid and permanently to the shank or to 'between-sole.

[32] In this way, the invention improves the technique for assembling together the parts of a shoe sole and improves the quality and durability of the result of the assembly of parts of a multi-piece shoe sole .
