Description

  The present invention relates to an improvement of an insole that is detachably inserted into a shoe.

  Conventional insoles of shoes are generally made from various flat fibers, rubber, synthetic resin, etc. by press cutting from these flat plate materials. In addition, in order to stimulate the acupuncture points on the soles, healthy type products with many protrusions formed on the surface of the insole are manufactured by attaching the protrusions to the flat insole body later by bonding or the like. ing. (For example, see Patent Document 1)

Utility model registration No. 3090808

  However, with the flat insole, the thickness is uniform and thin, so there is not enough cushioning, and uncomfortable pain may be felt during walking, and the surface is flat as a whole, Since it does not follow the shape of the sole, there is a problem that the fit with the sole is poor and the fit to the foot is poor. Further, the manufacturing method in which the acupuncture stimulating protrusion is attached later has two manufacturing steps, which increases the manufacturing cost and has the disadvantage that the protrusion is easily detached during use.

  The present invention eliminates these points and provides an insole that is flexible, highly cushioning, fits well with the sole, and is comfortable to wear. Furthermore, the present invention is to provide an insole that is formed integrally and three-dimensionally.

  The insole of the shoe of the present invention is made integrally by an injection molding method in which ethylene vinyl acetate copolymer resin is heated and injected into a mold, and the substrate portion having a peripheral shape matched to the shoe has its thickness. However, it is thin on the toe side and thick on the heel side, and the base plate part is gently curved in the longitudinal direction so that the toe part and the arch part are higher than the other parts. In addition, the substrate part is also gently curved in the width direction, the peripheral part is slightly higher, and on the periphery of the collar part, a bulging wall part is formed in an inclined shape. Furthermore, a large number of protrusions for stimulating the sole of the foot are formed on the surface of the substrate portion.

  Also, a plurality of narrow grooves for promoting bending may be formed on the back surface of the substrate portion. Further, a plurality of through holes for draining water may be formed on the plate surface of the substrate portion. Moreover, you may form a protrusion in the circumferential direction in the outer wall of the bulging wall part of a collar part. Furthermore, the shape of the protrusions may be asymmetrical for the left and right feet, and a large number of minute protrusions may be formed on the upper surface of the protrusions.

  The insole of the present invention is made by an injection molding method using ethylene vinyl acetate copolymer resin, and the thickness is thin on the toe side and thick on the heel side, and also in the longitudinal direction and in the width direction. In addition, a bend is provided, and a bulging wall portion is formed in an inclined shape on the periphery of the collar portion. That is, since it is three-dimensionally formed, it has an advantage that it fits well on the sole, is extremely comfortable to wear, and is difficult to remove. Since it is made of a thick ethylene vinyl acetate copolymer resin, the cushioning effect is high, and a sufficient impact absorbing effect is obtained. In addition, since the ethylene vinyl acetate copolymer resin is a soft material, it can flexibly cope with the shape of the foot with individual differences, and since the heat insulation effect is high in terms of material, a heat retaining effect can also be expected. Moreover, since the toe is raised by the curve forming, the stability during walking is good and the tripping can be prevented. Furthermore, since the insole of the present invention has a large number of protrusions on the surface, it can stimulate the acupoints of the soles during walking and can be expected to promote health. In addition, since the insole can be freely attached to and detached from the shoe, it can be easily replaced when damaged, can be used according to the application, and can be taken out and hand-washed easily. In addition, when molded to a specific shoe, the stability in the shoe is very good and the comfort is also perfect. Furthermore, since the insole of the present invention is integrally formed as a whole, it has good durability, is easy to manufacture, and can be provided at low cost.

  According to the second aspect of the present invention, the flexibility of the insole is enhanced by the narrow groove, so that it can be well adapted to the torsion of the foot during exercise.

  According to the third aspect of the present invention, since there is a through hole, sweat collected on the sole of the foot and water that has entered from the outside can be removed, and there is a ventilation effect, so the feeling of use is very good.

  According to the fourth aspect of the present invention, since the ridge is attached to the heel part and the shoe is attached to the shoe, the insole is always pressed against the insole by the elasticity of the ridge. Good stability within.

  According to the fifth aspect of the present invention, since the minute protrusions are attached, there is an advantage that foot slip during walking can be prevented, fit property is good and it is difficult to take off. In addition, the sole and the surface of the protrusion do not completely adhere to each other, and a space is formed between the sole and the foot, and it is possible to prevent slimming due to sweat from the foot or water entering from the outside. Further, since the protrusions are asymmetrical for the left and right feet, the projections correspond well to the reflection areas of the soles by oriental medicine, and effective stimulation can be applied to the soles.

The best mode of the insole of the present invention will be described with reference to the drawings. An ethylene vinyl acetate copolymer resin (hereinafter referred to as EVA) is used as the material for the insole of the present invention. As a manufacturing method, an injection molding method, that is, a method of heating and fluidizing a resin, injecting and injecting the resin into the mold, and cooling and solidifying the mold is used. For this reason, an insole of a free shape can be made by changing a metal mold | die. In addition to adjusting the thickness, molding is free, such as adding irregularities and curves, and it is easy to manufacture an insole that is three-dimensional and integrated as a whole. Furthermore, since the hardness of the material can be adjusted during the manufacturing process by adjusting the resin used, it is possible to freely make an insole according to the application.
In addition, the present invention can be used as a general-use insole used for general shoes, but the present invention is mainly used as a dedicated insole used only for one type of specified shoe. Can expect great effect.

  Next, the embodiment of FIGS. 1 to 5 will be described in detail. FIG. 1 is a center cut end view, and reference numeral 1 denotes an insole substrate portion. The thickness is thin on the toe side and thick on the heel side. In the embodiment, the foot side is about 2 to 4 mm, and the heel side is about 4 to 6 mm. Furthermore, it is gently curved as a whole, and the toe portion and the arch portion are higher than the others. In the embodiment, the height of the foot is about 5 to 7 mm, and the height of the arch is about 6 to 8 mm. Furthermore, in the heel part, the peripheral part is raised in a curved shape according to the shape of the foot, and the bulging wall part 2 is formed in an inclined shape.

  A large number of projections 3 for acupoint stimulation are formed on the surface of the substrate portion 1. 2-5 mm is appropriate for the height of the protrusion 3. The protrusion 3 is positioned in accordance with the position of the acupoint on the sole, and the size and shape are determined. Since the points on the human foot are different on the left and right, the shape and position of the protrusions are also different on the left and right insole, making it asymmetrical. In addition, a slight difference in height may be provided in the height of the protrusions to enhance the stimulating effect of the acupuncture points or to improve the fit to the foot. Further, a minute protrusion 4 having a height of 1 to 2 mm is provided on the upper surface of the protrusion 3 that contacts the sole. As a result, slipping between the protrusion and the sole can be eliminated, and the both can be prevented from coming into close contact with each other, thereby improving the comfort.

  An appropriate number (10 to 15) of through holes 5 to the front and back surfaces having a diameter of 1 to 3 mm are provided on the plate surface of the substrate portion 1 at appropriate positions. Thereby, the water etc. which accumulated inside can be extracted, and it can also have air permeability. Further, a protrusion 6 having a height of 2 to 5 mm is provided on the outer surface of the bulging wall portion 2 in the circumferential direction. For this reason, when the insole is inserted into the shoe, the ridge 6 contacts the inner wall of the shoe and constantly applies a pressing force toward the toe to the insole. Improves insole stability. Furthermore, an appropriate number of narrow grooves 7 having a width of 1 to 3 mm and a depth of 1 to 2 mm are formed on the back surface of the substrate portion 1 in the vertical and horizontal directions. Accordingly, the flexibility of the insole is improved, and the insole is also adapted to the torsion of the foot during exercise.

  The present invention is not limited to the above-described embodiments, and can be freely modified within the scope of the claims of the utility model registration.
