Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an insole which is flat in appearance, has a shiatsu effect when worn, is clean, and can cope with design properties.

[0002]

[Prior art]

 Conventionally, there are shoes, sandals, and insoles provided with protrusions on the inner sole and the like for sole acupressure. The insole, insole, and insole protrusions are located at the locations of the acupressure points in oriental medicine and the acupuncture points of the acupuncture and moxibustion, and the shape, area, height, number, etc., are set as appropriate, and numerous on the entire sole. Some of them are arranged individually, some are provided only on some of the points, and the like. The shapes of the projections are also various, such as point-like and linear.

[0003] In recent years, materials and shapes of projections include polyurethane resin, vinyl-based, rubber-based materials, and wooden and bamboo materials. The space between the projections is also useful for preventing stuffiness and breathability, and is relatively popular.

However, the insole provided with the acupressure protrusion also has room for improvement in terms of comfort, design and cleanliness.

[0005] The protrusion has a structure that gives a painful feeling to the sole of the foot depending on the material or shape, causes dust or sock lump to accumulate in the gap between the protrusions, causes smell, and causes a problem in hygiene. The structure is not suitable for long-time wear.

[0006]

[Problems to be solved by the invention]

 The present invention is designed so that the sole of the sole is flat in appearance, but has a protrusion with acupressure effect where it cannot be seen from the surface without impairing the ventilation of the sole. It responds to design and hygiene requirements without sacrificing the goodness of the projections, has cushioning properties, is less tiring even when worn for a long time, does not hurt, has a variety of designs, and the projections are exposed. The purpose is to provide a clean insole with no luxury.

[0007]

[Means for Solving the Problems]

 The present invention addresses the above-mentioned problem, and is an insole that basically includes a surface layer (1), which is a foam, and a bottom layer (3) with projections (30). The surface layer (1), which is a foam, covers the bottom layer (3) with the projections (30), but has a cushioning property of its own and makes the projections (30) feel soft. The surface layer (1) is made of a material such as sponge and has air permeability, and covers and hides the projections visually, so that the presence of the projections is not visible on the external appearance. The design can have various changes.

[0008] The present invention provides an insole characterized by covering a bottom layer (3) with a protrusion (30) for sole acupressure by a surface layer (1) which is a flexible foam. Since the hardness of the surface layer (1) is such that the protrusions (30) appropriately arranged on the bottom layer (3) can be felt, the surface layer is visually covered and has a painless finish. I have. Specifically, the hardness of the surface layer (1) is preferably 40 degrees or less, while the hardness of the protrusions (30) appropriately arranged on the bottom layer (3) is 60 to 100 degrees. Better. The difference in hardness between the surface layer (1) and the protrusions (30) appropriately arranged on the bottom layer (3) allows the cushioning and the acupressure effect to be felt when the insole is worn.

The surface layer (1), which is a foam, is a gas permeable material having a large number of air holes, and enters the gaps between the projections (30) to fill the gaps. The surface layer (1), which is a foam, can be impregnated with a deodorant or a deodorant, provided with a groove for exhaust on the surface, or provided with various functions or designs. The surface layer (1), which is a foam, is a soft resilient or resilient material, and a surface cloth (10) may be further provided on the upper surface. An insole corresponding to the intended use can be created by providing the surface cloth (10). For example, if the entire covering is made of a waterproof material, the insole can be waterproof.

[0010] The structure and method of integrating the surface layer (1), which is a flexible foam, with the bottom layer (3) with the projections (30) are not particularly limited and are not limited. An adhesive layer may be provided by bonding with an adhesive, or heat welding may be performed.

The bottom layer (3) with the projections (30) needs to be felt by the projections (30) pressing the acupressure effect to some extent. Materials such as transparent, translucent, opaque, etc. of flexible foam, and colors and patterns can be selected as appropriate, but setting the hardness is one of the key points of the present invention. The surface layer (1), which is a foam, is made of a material such as sponge, and has many ventilation holes, and is breathable, flexible, and compressed to bring the soles close to the protrusions. Touch the appropriately arranged protrusions (30). It is very sanitary in that the ventilation between the protrusions can be maintained, and no dust can enter.

In the present invention, the hardness of the surface layer (1) is 40 degrees or less, while the hardness of the projections (30) appropriately arranged on the bottom layer (3) is 60 to 100 degrees. Although it is preferable that the angle is about 30 degrees, it is more preferable.

[0013]

 FIG. 1 is a plan view showing an embodiment of the insole according to the present invention. 2 to 5 are cross-sectional views of each part. FIG. 6 is a see-through plan view of a state before cutting with the outer cloth (10) covered, and FIGS. 7 and 8 are cross-sectional views of various parts thereof. A preferred embodiment of the insole is obtained by superposing each member in multiple layers. When viewed from the top, in order, the surface cloth (10), the surface layer (1) which is a foam, the bottom layer (3) with the projection (30), and Consisting of three layers.

The surface layer (1), which is a foam, has a height that is at least thicker than each of the numerous projections (30). A breathable material such as a sponge is preferred, but it may be formed of a non-breathable, resilient material. Candidates include PU (polyurethane) -based foam, PE-based foam, EVA-based foam, rubber-based foam, etc., and the expansion ratio of the material is within the range where the shape retention and cushioning properties can be maintained. Becomes

[0015] The outer fabric (10) is not an essential requirement of the present invention, but when a product utilizing the present invention is used, it may be made of cloth or leather for decoration or moisture absorption, or may be required depending on the application. It can be appropriately selected for use, such as one that has undergone a certain secondary processing (spray processing with a moisture absorbent or water repellent). Antibacterial, deodorant, and mildew-proof treatments, and the use of a hygroscopic material with a refreshing feeling can be selected. Other materials can be selected as appropriate, such as those using fibers mixed with ceramic powder that generates far-infrared rays, those using fibers mixed with copper powder for antibacterial purposes, and those that have been waterproofed. Whether such secondary processing is performed on the surface cloth (10) or on the surface layer (1) itself is only a matter of choice corresponding to the use or purpose.

【Example】

 On the surface of the bottom layer (3), projections (30) serving as acupoints were formed on the bottom of the sole, the center of the foot, and the anterior part for stimulating the acupoints on the soles of the feet. The size of the protrusion (30) is 7 mm in diameter, 5 mm in diameter, and 4 mm in diameter. The projection (30) is formed in a bulging shape for each part to be pressed.

The bottom layer (3) having the projections (30) formed thereon was joined with a surface layer (1), which is a foam having relatively formed recesses in advance, and integrated. Means for joining the surface layer (1), which is a foam, to the bottom layer (3) having the projections (30) formed thereon is as follows. Or a method in which the bottom layer (3) having the projections (30) formed thereon is attached to a mold, and the surface layer (1) is simultaneously bonded while thermoforming the material. The means of joining the bottom layer (3) and the surface layer (1) can be selected to suit the material. The surface layer (1), which is a foam, is prepared by spraying or impregnating a quaternary ammonium salt solution onto a polyurethane foam formed in advance in a relative shape, or chitin obtained by chemically treating a shell such as crab or okiami. Mixing of chitosan fine powder and catechin, saponin and carboxylic acid aqueous solution for plant extraction and purification in zeolite, silica gel, aluminum oxide, zinc oxide, silicon dioxide, etc. Then, the powder was spread and dispersed, and the hardness was set to 30 degrees using, for example, a trial.

[0018]

[Effect of the invention]

 The insole according to the present invention is configured as described above and has the following unique technical effects. It has a protrusion with an acupressure effect on the sole of the foot, and since the protrusion is not visible, it can be used for labeling and decorative processing, so it has a higher quality than a bare, exposed protrusion. Since the surface layer has cushioning properties, it does not hurt even when worn for a long time. For example, when working in a standing position, it does not cause pain and can prevent fatigue as well as acupressure effects. Since the surface layer and / or the surface cloth is flat, the design can be expanded. In addition, since the gaps between the projections are buried, it is possible to respond to hygienic requirements without adhering dust or the like to the gaps. It can be kept clean even when worn for a long time. As described above, the insole of the present invention is a seemingly ordinary form of insole (insole / insole) having stimulating protrusions, and is hygienic, provides a cushioning acupressure effect, and provides a foot-friendly insole.
