Description

Shoe-pad

Technical Field

Background

A common shoe is mainly composed of a cloth or leather vamp which is adhered to a sole. The sole and the vamp form a space for the foot of the user to extend into and step on the sole. In consideration of the durability of the shoes, the sole is usually made of a resin material which is relatively wear-resistant and relatively hard. Therefore, in order to achieve both the comfort of the user wearing the shoe and to reduce the discomfort of the foot caused by the vibrations from the sole, an insole, which is softer than the sole, is often placed in the shoe.

The existing shoe pad is integrally formed by foamed synthetic resin or synthetic rubber, and although the basic feeling of foot softness can be provided, the whole shoe pad is made of synthetic materials, so that the shoe pad is not environment-friendly.

Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 3, a first embodiment of the insole of the present invention is adapted to be placed on a sole 92 of a shoe 91 for contacting a user's foot (not shown) so that the foot does not directly step on the sole 92. The shoe 91 may be, but is not limited to, an athletic shoe, a casual shoe, a leather shoe, or a high-heeled shoe … …, among others.

The insole is approximately matched with the sole of a user and is provided with a bearing layer 1 and a coating layer 2 combined on the bearing layer 1.

The carrier layer 1 is in the shape of a plate and has a bottom surface 11 adapted to face the sole 92, and a first coupling surface 12 spaced from and opposite to the bottom surface 11.

The carrier layer 1 includes a substrate 13 and a plurality of particles 14 dispersed on the substrate 13 and at least partially covering the substrate 13. The substrate 13 is made of one selected from the group consisting of Polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), Polyolefin elastomer (POE), Thermoplastic elastomer (TPE), and rubber, in which the rubber may be natural rubber or synthetic rubber, in this embodiment, the substrate 13 is selected from synthetic rubber or natural rubber, in other variations of this embodiment, the substrate 13 is selected from cross-linked Polyurethane.

The particles 14 are irregularly shaped. One part of the particles 14 is completely covered in the substrate 13, and the other part is exposed from the substrate 13 and forms the bottom surface 11 and the first bonding surface 12 together with the substrate 13. The particles 14 are made of at least one material selected from the group consisting of polyurethane, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyolefin elastomer, thermoplastic elastomer, and rubber. In practice, the rubber may be natural rubber or synthetic rubber. In this embodiment, the particles 14 are made of a high molecular synthetic resin, specifically, a crosslinked ethylene-vinyl acetate copolymer, and the particle size (particle size) of each particle 14 is 0.1mm to 10 mm. In addition, when the weight percentage based on the substrate 13 is 100 wt%, the weight percentage of the particles 14 is 10 wt% to 50 wt%, so that the particles 14 are surely bonded to the substrate 13, and have good elasticity and structural strength, and are not easily broken or the particles 14 are separated from the substrate 13 even by folding or twisting.

In this embodiment, when manufacturing the carrier layer 1, a softened base preparation material and the particles 14 are first mixed to form a mixture, and then the mixture is placed into a mold for hot press molding, according to the material of the base 13, taking the base 13 as synthetic rubber or natural rubber, the heating temperature is 140 ℃ to 160 ℃, and the heating time is 5 minutes to 10 minutes, so as to manufacture the carrier layer 1. In addition, a boundary region is formed between the particles 14 and the substrate 13.

The pasting layer 2 substantially conforms to the shape of the bearing layer 1, is suitable for being spaced from the sole 92, and has a second combining surface 21 combined with the first combining surface 12 of the bearing layer 1 through pressing, and a top surface 22 spaced from and opposite to the second combining surface 21 and suitable for being stepped on. The coating layer 2 has a thickness D1 ranging from 0.5mm to 9mm from the second bonding surface 21 to the top surface 22, and includes a recycled fabric layer.

The recycled cloth layer body is formed by cutting various cloth materials which are recycled without being used into broken cloth, breaking original textures on the broken cloth and further disassembling into fibers, or carrying out the steps of interweaving, mutually twisting, directly winding or laminating on the fibers again to form an uncut recycled cloth layer, and finally cutting the recycled cloth layer into a shape which is consistent with the bearing layer 1 before or after being combined with the bearing layer 1 to form the attaching layer 2, wherein the recycled cloth layer is made of the recycled cloth material, and the original textures of the recycled cloth material are broken into the fabric pieces, or the recycled yarn, the recycled fiber … … and the like. The material of the recovered fabric layer may be a composite of raw rag, yarn, fiber … …, and the like, and may be selected from a group consisting of plant fiber, animal fiber, artificial fiber, and a combination thereof. Specifically, the recycled fabric layer is made of plant fibers and artificial fibers.

When in use, the insole can be directly and removably placed on the top surface of the sole 92, or directly adhered to the sole 92 with an adhesive (not shown), and when a user wears the shoe 91, the user can step on the insole without directly contacting the relatively hard sole 92, thereby maintaining the comfort of walking or standing while wearing the shoe for a long time.

The recycled cloth layer is made of recycled cloth, yarn, fiber … … and the like which are not needed, and the cloth can be made of various clothes, fabrics or non-fabrics instead of completely new and useless natural fiber or synthetic fiber, so that the waste amount is effectively reduced, the cloth can be recycled, and the environment protection is greatly benefited.

In addition, by utilizing the air permeability of the sticking layer 2, the moisture generated by the feet can be dissipated to the outside, and is not easy to accumulate in the shoes 91, thereby causing the feeling of stuffiness and dampness or breeding bacteria. Furthermore, the design of the particles 14 of the carrier layer 1 provides sufficient structural strength to the insole as a whole.

Referring to fig. 3, a second embodiment of the insole of the present invention is similar to the first embodiment, except that the particles 14 of the supporting layer 1 are made of recycled fabric.

The recycled fabric of the particles 14 is the same as the recycled fabric layer of the coating layer 2, but the two are different. The coating 2 is a complete layer structure and the particles 14 are granular structures that have been cut to a predetermined volume or size.

In other variations of this embodiment, the particles 14 may be made of a recycled fabric and the particles 14 of the first embodiment. Therefore, the material of the particles 14 may be at least one selected from the group consisting of Polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), Polyolefin Elastomer (POE), Thermoplastic Elastomer (TPE), synthetic rubber, natural rubber, and cloth.

Referring to fig. 4, a third embodiment of the insole of the present invention is similar to the first embodiment, except that the insole of the third embodiment further comprises a top cloth layer 3 coupled to the top surface 22 of the adhesive layer 2.

The thickness of the top cloth layer 3 is smaller than that of the attachment layer 2, and is made of single-layer non-woven fabric or general fabric.

To sum up, the utility model discloses an insole utilizes this bearer layer 1 granule 14 spreads in this basement 13, promotes this bearer layer 1's structural strength and holding power. On the other hand, the sticking layer 2 is the recycled cloth layer body, can fully utilize various cloth and rag which are not used originally, further reduce the output of garbage wastes, and is environment-friendly, so that the purpose of the utility model can be achieved.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
