Disclosure of Invention
Problems to be solved by the invention
The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an insole and an insole kit for a shoe, which can make walking by wearing a shoe worn on a flat day without specially wearing a special style shoe or a special harness, and which can unconsciously exercise foot strength according to the foot strength of the wearer and the health state of the wearer at that time.
Means for solving the problems
In order to solve the above problems, the invention according to claim 1 is an insole for a shoe in which an upper insole made of polyurethane foam is attached to an upper surface of a lower insole made of a mixed substance in which a rubber material and a stainless steel material are mixed at a predetermined ratio, wherein the weight of the insole is variable and the thickness and the size of the insole are not changed by appropriately changing the mixing ratio of the rubber material and the stainless steel material of the mixed substance for forming the lower insole from 60% to 40% with respect to 40% of the rubber material.
The invention according to claim 2 provides an insole for a shoe, in which an upper insole formed of a polyurethane foam is attached to an upper surface of a lower insole formed of a mixed substance in which a rubber material and a barium sulfate material are mixed at a predetermined ratio, wherein the weight and thickness of the insole are made variable by appropriately changing the mixing ratio of the rubber material and the barium sulfate material of the mixed substance forming the lower insole from 60% to 40% with respect to 40% of the rubber material.
The invention of claim 3 is characterized in that an insole having lighter weight and constant thickness and size is manufactured by covering an upper insole formed of polyurethane foam on a lower insole formed of a foamed raw material of ethylene-vinyl acetate copolymer resin.
The invention described in claim 4 is a set of insoles, wherein the set of 1 includes an upper insole formed of polyurethane foam described in claim 1 to 3, a lower insole formed of a mixture of a rubber material and a stainless steel material mixed at a predetermined ratio described in claim 1, a lower insole formed of a mixture of a rubber material and a barium sulfate material mixed at a predetermined ratio described in claim 2, and a lower insole formed of a foamed material of ethylene-vinyl acetate copolymer resin described in claim 3, wherein one of the three types of lower insoles having different weights is arbitrarily selected and the upper insole is attached thereon, whereby an insole having a desired weight and a constant thickness and size can be worn.
Effects of the invention
In the shoe insole according to the invention described in claim 1, a mixture of a rubber material and a stainless steel material having different specific gravities is used as the lower insole, so that a heavy insole (heavy insole) having a high load for enhancing foot strength can be obtained by utilizing cushioning properties of the rubber material and weight properties of the stainless steel material. Thus, even if a user does not wear special shoes or uses special harnesses, the user can unconsciously exercise to fully exercise the foot by walking with shoes worn on a flat day.
In the shoe insole of the shoe according to the invention described in claim 1, the weight of the load can be arbitrarily changed without changing the thickness and size of the entire shoe insole by appropriately changing the blending ratio of the rubber material and the stainless steel material forming the lower insole within the range of 60% stainless steel material to 40% stainless steel material with respect to 40% rubber material.
For example, if the volume of the entire insole is 250cc, the volume of the upper insole made of polyurethane foam is 165cc, and the volume of the lower insole is 85cc, the specific gravity of the lower insole made of a rubber material having a specific gravity of 1.1 of 60% and a stainless steel material having a specific gravity of 8.0 of 40% (minimum value) is about 3.53, and the weight thereof is about 300g (volume 85cc × specific gravity 3.53 (rounded to the decimal point, the same shall apply hereinafter). If the weight of the upper insole made of polyurethane foam is about 25g, the whole becomes about 325g of insole. When the blending ratio of the lower insole is 40% by weight of the rubber material and 60% by weight of the stainless steel material (maximum), the specific gravity of the lower insole is about 5.24, and the weight thereof is 85cc by 5.24, which is about 445 g. If the weight of the upper insole made of polyurethane foam is about 25g, the whole becomes about 470g of insole.
That is, according to the invention described in claim 1, it is possible to appropriately produce insoles of about 325g to about 470g without changing the thickness and size, and to obtain weight insoles having a load weight more effective for enhancing foot strength without impairing the wearing feeling.
The insole of the shoe according to the invention described in claim 2 uses the rubber material and the barium sulfate material having different specific gravities as the lower insole, and thus can produce an insole (medium insole) having a load weight of a medium level effective for enhancing the foot power, by utilizing the cushioning property of the rubber material and the weight property of the barium sulfate material. Thus, even if a shoe of a special style is not specially worn or a harness is not used, the user can do exercises without particular awareness by walking with the shoe worn on a weekday, and thereby exercise the foot strength.
In the shoe insole of the shoe according to the invention described in claim 2, the weight of the load can be arbitrarily changed without changing the thickness and size of the insole by appropriately changing the blending ratio of the rubber material forming the lower insole and the barium sulfate material within the range of 60% barium sulfate material to 40% barium sulfate material to 60% rubber material.
For example, in the same manner as in claim 1, when the volume of the entire insole is 250cc, the volume of the upper insole made of polyurethane foam is 165cc, and the volume of the lower insole is 85cc, the specific gravity of the lower insole made of 60% of the rubber raw material having a specific gravity of 1.1 and 40% (minimum value) of the barium sulfate raw material having a specific gravity of 4.2 is 2.34, and the weight thereof is 85cc by 2.34 which is about 199 g. If the weight of the upper insole added thereto is about 25g, the whole becomes about 224g insole. In addition, the lower insole, which is made of 40% rubber material having a specific gravity of 1.1 and 60% (maximum value) barium sulfate material having a specific gravity of 4.2, has an average specific gravity of 2.96 and a weight of 85cc in volume × 2.96 to about 252 g. If the weight of the upper insole added thereto is about 25g, the whole becomes about 277g insole.
That is, according to the invention of claim 2, it is possible to appropriately produce insoles of about 224g to 277g without changing the thickness and the size, and to obtain medium-sized insoles having a load weight effective for enhancing foot strength without impairing the wearing feeling.
The insole of a shoe according to the invention described in claim 3 can be made into a lightweight insole (light insole) with a light load by using a foamed material of an ethylene-vinyl acetate copolymer resin (abbreviated as "EVA") as the lower insole.
For example, in the same manner as in the inventions of claims 1 and 2, when the volume of the entire insole is 250cc, the volume of the upper insole is 165cc, and the volume of the lower insole is 85cc, the specific gravity of the lower insole made of a material obtained by foaming EVA having a specific gravity of 0.92 by about 3 times is about 0.3, and the weight thereof is 85cc in volume × about 0.3 to about 26g in specific gravity. If the weight of the upper insole added thereto is about 25g, the whole becomes about 51g insole.
The insole of the shoe according to the invention described in claim 3 is lightweight and cannot expect the effect of increasing the foot force due to the load increase, but has the same thickness and size as the insole of claim 1 or the insole of claim 2, and therefore can provide a wearing feeling equivalent to that when wearing these heavy insoles or medium insoles.
The shoe insole kit according to the invention of claim 4, wherein 1 of the 3 kinds of lower insoles having different weights is arbitrarily selected and the upper insole is attached to the upper insole of the shoe insole set 1 consisting of the upper insole formed of the polyurethane foam of claim 1 to 3, the lower insole of claim 1, the lower insole of claim 2 and the lower insole of claim 3, whereby 3 kinds of insoles having different weights and constant thicknesses and sizes can be obtained, and thereby the most suitable insole can be selectively worn according to the leg strength and daily physical condition of the wearer.
