Description

insole

The new model relates to a shoe material, especially an insole that is good to the environment.

Normal shoes are mainly composed of a cloth or leather upper which is glued to a sole. The shoe sole and the shoe upper jointly form a space for the user's feet to extend into and step on the shoe sole. Under the premise of considering the durability of shoes, a more wear-resistant and relatively hard resin material is usually used to make shoe soles. Therefore, in order to take into account the user's comfort in wearing shoes, and to reduce the discomfort caused by the vibration from the sole of the shoe, most people put an insole that is softer than the sole of the shoe in the shoe.

The current insole is made of foamed synthetic resin or synthetic rubber. Although it can provide the basic feeling of softness of the foot, the whole is made of synthetic material, which is not environmentally friendly.

Therefore, the object of the present invention is to provide an insole that can at least overcome the shortcomings of the prior art.

Therefore, the insole of the present invention is suitable for placing on a shoe sole, and the insole includes a bearing layer and a sticking layer.

The load-bearing layer has a bottom surface suitable for facing the sole, and includes a base, and a plurality of particles dispersed and respectively coated in the base. The particles are made of Polyurethane (PU for short) , Ethylene-vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), polyolefin elastomer (POE), thermoplastic elastomer (Thermoplastic Elastomer (referred to as TPE), synthetic rubber, natural rubber, and cloth consisting of at least one substance selected from the group of substances.

The sticking layer is combined on the bearing layer and is suitable for being spaced from the sole of the shoe, and the sticking layer includes a recycled fabric layer.

The effect of the new model is that the particles of the bearing layer and the design of the covering layer are used to enable the insole to have the advantages of comfort, air permeability and environmental protection under the condition of sufficient structural strength.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

1 to 3, a first embodiment of the insole of the present invention is suitable for being placed on a sole 92 of a shoe 91 to contact a user's foot (not shown), so that the foot will not Step directly on the sole 92. The shoes 91 can be, but are not limited to, sports shoes, casual shoes, leather shoes, or high-heeled shoes...etc.

The insole roughly conforms to the shape of the user's sole, and has a bearing layer 1 and a covering layer 2 combined with the bearing layer 1.

The load-bearing layer 1 is in the shape of a sheet, and has a bottom surface 11 suitable for facing the sole 92 and a first bonding surface 12 spaced and opposite to the bottom surface 11.

The supporting layer 1 includes a substrate 13 and a plurality of particles 14 scattered on the substrate 13 and at least partially covering the substrate 13. The substrate 13 is made of polyurethane (Polyurethane, referred to as PU), ethylene-vinyl acetate copolymer (abbreviated as EVA), polyvinyl chloride (Polyvinylchloride, referred to as PVC, polyolefins) Polyolefin elastomer (POE for short), Thermoplastic elastomer (TPE for short), synthetic rubber, and natural rubber are selected from the group of substances. In this embodiment, the substrate 13 is selected from Synthetic rubber and natural rubber. In other variations of this embodiment, the substrate 13 is selected from a cross-linked polyurethane.

The particles 14 have irregular shapes. A 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, synthetic rubber, and natural rubber. In this embodiment, the particles 14 are made of a polymer synthetic resin, specifically a cross-linked ethylene-vinyl acetate copolymer, and the size of each particle 14 is 0.1 mm-10 mm. In addition, when the weight percentage based on the substrate 13 is 100% by weight, the weight percentage of the particles 14 is 10% to 50% by weight, so that the particles 14 are indeed combined with the substrate 13 and have good elasticity and The structural strength is not easy to break even after being folded or twisted, or the particles 14 are separated from the substrate 13.

In this embodiment, when the carrier layer 1 is made, a softened substrate preparation material and the particles 14 are mixed to form a mixture, and then the mixture is put into a mold for hot pressing. According to the material of the substrate 13 Differently, taking the base 13 as synthetic rubber or natural rubber as an example, the heating temperature is 140° C. to 160° C., and the heating time is 5 minutes to 10 minutes, and the bearing layer 1 is prepared. In addition, a boundary area is formed between the particles 14 and the substrate.

The covering layer 2 roughly conforms to the shape of the carrier layer 1, and is suitable for being spaced from the sole 92, and has a second bonding surface 21 bonded to the first bonding surface 12 of the carrier layer 1 by pressing, And an interval and opposite to the second joint surface 21 and suitable for the top surface 22 for foot pedaling. The covering layer 2 has a thickness D1 ranging from 0.5 mm to 9 mm from the second bonding surface 21 to the top surface 22, and includes a recycled fabric layer.

The recycled fabric layer is made by cutting all kinds of fabrics that are no longer needed and recycled into rags, and after destroying the original weaves on the rags and further disassembling them into fibers, or the recycled yarn, Fiber... etc., all the fibers are re-weaved and twisted, directly wound or laminated to form an uncut recycled fabric layer, and finally, before or after being combined with the carrier layer 1, the recycled fabric The layer is cut into a shape conforming to the carrier layer 1, and an adhesive layer 2 is produced. In addition, the material of the recycled fabric layer can also be a composite of original rags, yarns, fibers, etc., and selected from plant fibers, animal fibers, man-made fibers, and a combination of these. Specifically, the recycled fabric layer is made of plant fibers and man-made fibers.

When in use, the insole can be directly detachably placed on the top surface of the sole 92, or directly adhered to the sole 92 with an adhesive (not shown), and used for a user to wear shoes 91, the foot It can step on the insole without directly contacting the harder sole 92, and can maintain the comfort of wearing shoes for a long time and walking or standing.

Since the source of the recycled fabric layer is to recycle fabrics, yarns, fibers, etc. that are no longer needed, the source of the fabrics can be all kinds of clothes, fabrics or non-fabrics, not new and unused natural fibers Or made of synthetic fiber, which effectively reduces the amount of waste and enables the fabric to be recycled again, which is of great help to environmental protection.

In addition, by using the air permeability of the adhesive cover layer 2, the moisture generated by the feet can escape to the outside, and it is not easy to accumulate in the shoes 91, causing a feeling of stuffiness or breeding of bacteria. Furthermore, the design of the particles 14 of the bearing layer 1 enables the insole to have sufficient structural strength as a whole.

Refer to Fig. 3, which is a second embodiment of the new insole. The second embodiment is similar to the first embodiment, except that the particles 14 of the carrier layer 1 are made of recycled fabric.

The recycled fabric of the particles 14 and the recycled fabric layer of the covering layer 2 have the same material, but the two aspects are different. The covering layer 2 is a complete layer structure, and the particles 14 are granular structures that have been chopped into predetermined volumes or sizes.

In other variations of this embodiment, the material of the particles 14 can also be a combination of recycled fabric and the particles 14 of the first embodiment. Therefore, the material of the particles 14 can be made of polyurethane (Polyurethane, referred to as PU), ethylene-vinyl acetate copolymer (abbreviated as EVA), polyvinyl chloride (Polyvinylchloride, referred to as PVC), Polyolefin elastomer (POE for short), Thermoplastic Elastomer (TPE for short), synthetic rubber, natural rubber, and cloth are at least one selected from the group of substances.

Refer to FIG. 4, which is a third embodiment of the new insole. The third embodiment is similar to the first embodiment. The difference is that the insole of the third embodiment also includes a cover layer 2 bonded to the The surface cloth layer 3 of the top surface 22.

The thickness of the surface cloth layer 3 is smaller than the thickness of the covering layer 2, and is made of a single layer of non-woven fabric or general fabric.

In summary, the insole of the present invention utilizes the particles 14 of the load-bearing layer 1 to be dispersed in the base 13 to improve the structural strength and supporting force of the load-bearing layer 1. On the other hand, the pasting layer 2 is the recycled fabric layer body, which can make full use of all kinds of fabrics and rags that are not used before, thereby reducing the output of garbage and waste, which is environmentally friendly, so it can indeed achieve a new cost The purpose.
