JPH03126401A - Inner cushion of shoe - Google Patents

Abstract

PURPOSE:To eliminate moisture of the tip of a foot by ventilating the inside of a shoe by allowing instep leather of the inner cushion to have elasticity, and also, forming an air chamber on its lower face, and moreover, forming a blowout hole of air in the vicinity of the tip and allowing it to conduct to the air chamber. CONSTITUTION:The inner cushion is formed by superposing bottom leather 2 under instep leather 1 formed by using a sheet material having scarcely or no gas transmissible property at all of synthetic rubber and synthetic resin, etc., and joining its peripheral edge like a bag. Subsequently, by inserting a continuous bubble body 3 having moderate flexibility and elasticity such as polyurethane foam, etc., therein, an air chamber is formed, and also, the instep leather 1 is allowed to have elasticity. Also, blowout holes 5 of air are formed in the vicinity of the tip of the inner cushion and they are allowed to conduct to the air chamber, and also, an air hole 4 is pierced in the part of the heel of one of the instep leather 1 or the bottom leather 2. By putting on shoes in which this inner cushion is laid and allowing air to blow out of the tip of the inner cushion, ventilation in the shoes is executed and moisture in the tip of a foot can be eliminated.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a shoe insole.

More specifically, air is blown out from the tip every time it takes a step.

(Prior Art) Many footwear such as leather shoes and boots have their toes sealed. Therefore, when the temperature is high or when you exercise a lot, this area becomes stuffy and humid due to sweat and moisture generated from the tips of your feet.

Moreover, once the humidity becomes high, the condition continues while wearing leather shoes, etc., which is not only uncomfortable, but also causes a bad odor to come from the tips of the feet, which often leads to skin diseases such as athlete's foot. .

(Problem M to be solved by the invention) For this reason, socks that have the effect of treating athlete's foot and insoles containing a deodorant have been used in the past.

However, these do not have the desired effect1.
The effect is shown after the toes are infected with athlete's foot or have a bad odor, so it is a passive treatment method that removes moisture from the toes and removes the athlete's foot and bad odor. There was no effect on preventing the outbreak, so the dampness of the toes caused discomfort, bad odor, and athlete's foot.

SUMMARY OF THE INVENTION An object of the present invention is to provide a means for ventilating the inside of a shoe and removing moisture from the toes by blowing air out from near the tip of the insole.

(Means for Solving the Problems) The present invention utilizes the fact that when a person walks, the pressure force due to the body weight is first applied to the heel area, and the function of the air bomb 1 that is activated by this force is applied to the heel area of the shoe. Put it in the insole of
Each time you walk, a small amount of air is blown out from the vicinity of the tip, and the air contains an aromatic layer, athlete's foot deterrent, etc.

In other words, the insole of this shoe forms an air chamber under the upper skin of the heel, allowing air to enter this chamber, and also conducts this air chamber to the vicinity of the tip of the insole, and furthermore, This part is made to have elasticity so that it functions as an air pump, and when pressure is applied to this part, the air chamber shrinks and the air inside is forced out and blown out from the vicinity of the tip.

Also, a method is adopted in which a pocket is formed in the middle of the air conduction path and an aromatic agent, athlete's foot deterrent, etc. are loaded into the pocket.

(Function) The insole of the shoe according to the present invention forms an air chamber in the heel portion so that air can enter the chamber, and this portion functions as an air pump, so that the shoe insole is designed to function as an air pump. A small amount of air is blown out from near the tip. As a result, the leading edge of the footwear is ventilated by this air and moisture is removed.

Further, by loading an aromatic agent, an athlete's foot deterrent, etc. in the middle of the air passage, the air contains the aromatic agent, an athlete's foot deterrent, etc.

(Example) Hereinafter, the shoe insole according to the present invention will be specifically described based on Examples.

FIG. 1 shows an example of a shoe insole, in which reference numeral 1 is the upper skin and 2 is the sole skin.

Both the upper skin 1 and the sole skin 2 are made of synthetic rubber, synthetic street fat, etc.
Alternatively, it is formed using a sheet material that has no air permeability at all, and the two are stacked one on top of the other and their peripheral edges are joined to form a bag-like shape.

Then, an open cell material 3 having appropriate flexibility and elasticity, such as polyurethane foam, is inserted therein.

This open-cell foam 3 creates an air chamber between the upper skin 1 and the sole skin 2 so that air is contained in this area, and at the same time gives the upper skin 1 apparent elasticity. When weight is applied to the insole of the shoe, the upper skin 1 sinks due to the compressive force, the open-cell foam 3 contracts, and the air contained therein is pushed out. This gives it the function of an air pump.

Therefore, the open-cell foam 3 does not necessarily need to be inserted throughout the insole of the shoe.

Although it depends on the thickness of the open-cell foam 3, it can fully function if it is inserted only into the heel area. Of course, in this case, if the open-cell foam 3 is inserted over the entire insole of the shoe, an air chamber will be formed throughout the entire insole, and if it is inserted only into the heel, that part will become an air chamber, and the other parts will be It becomes an air conduction path 6.

A ventilation hole 4 is bored in the heel of either the upper skin 1 or the sole skin 2, through which air enters the air chamber, and further near the tip of the upper skin 1. Air blow holes 5 are provided.

This blow-off hole 5 is for blowing out the air contained in the open-cell foam 3 when weight is applied to the part of the shoe insole into which the open-cell foam 3 is inserted.

Therefore, this blowout hole 5 can not only be made in the upper 1, but also can be formed in the tip edge of the insole by not joining a part of the tip edges of the upper 1 and the sole 2. .

Moreover, when this is done, the tip of the insole functions as a pocket, and the air conduit 6 from the air outlet 5 to the upper skin 1 and the sole skin 2 is filled with air fresheners and athlete's foot. It becomes possible to load a drug 10 such as a deterrent.

As mentioned above, the insole of this shoe has an air chamber formed between the upper skin 1 and the sole skin 2, and is configured so that when pressure is applied to this part, the air inside will blow out from near the tip. Other than that, there is no difference from regular insoles of this type.

That is, the insole of this shoe is molded in the same shape as the insole of footwear such as boots or leather shoes, and is inserted into the insole to be loaded.

Although not shown, the surface of the upper 1 is appropriately colored and aesthetically treated, and is also treated to prevent slipping. In addition, those used for the purpose of promoting health have irregularities formed on the surface of the upper 1, so as to apply pressure stimulation to the soles of the feet.

Figure 2 shows that when you put your weight on the insole of a shoe, it presses against the bottom of the footwear, which allows the bottom of the footwear to function as the sole of the insole and gives elasticity to the upper itself. This figure shows an example in which an air chamber is formed between the upper and the bottom of the footwear. In the figure, reference numeral 7 is the upper, and 8 is the bottom of the footwear, such as boots or leather shoes.

The upper skin constitutes the main part of the insole of the shoe, and in particular, the heel part has a high instep surface, a skirt 71 is integrally molded around its periphery, and a recess 72 is formed on the lower surface. is formed, and a groove 73 is formed on the lower surface of the other portion.

As will be described later, this groove 73 serves as an air passage, and its proximal end is connected to the recess 72, and its distal end reaches the tip of the upper skin and forms the blowout hole 5.

The upper 7 is made of synthetic beet resin, such as polyethylene, having appropriate elasticity and flexibility, and when it is pressed against the bottom 8 of the footwear, the upper 7 is molded onto the surface of the bottom 8. It is curved to follow the shape and comes into close contact with the bottom surface 8.

Therefore, when the footwear is worn, the depression 72 becomes an air chamber, and the groove 73
becomes the air conduit. Since weight is applied to the heel each time the wearer walks, the compressive force causes this part to dent and function as an air pump.

Reference numeral 9 is a pocket. This device is used to attach a volatile chemical 10 such as an air freshener or athlete's foot deterrent, and is formed in the middle of an air conduction path.

When the drug 10 is attached to this, the air pushed out from the air chamber passes through while contacting the drug 10, so the drug 1
A part of the 0 evaporates and is contained in it and is blown out.

(Effects of the Invention) As described in detail above, the insole of the present invention forms an air chamber under the upper skin of the heel portion, and allows air to enter the air chamber. The insole is electrically conductive to the tip of the insole, and has elasticity at the heel.With this structure, the insole acts as an air pump.
function. Therefore, each time the wearer walks, the air chamber contracts due to the compressive force applied to the heel portion of the insole, and the air inside is forced out, and this air is blown out from near the tip of the insole.

As a result, this air ventilates the tip of the footwear and removes moisture from the toes, eliminating the discomfort caused by stuffy toes and suppressing the occurrence of athlete's foot and bad odors.

In particular, by forming a pocket in the middle of the air conduction path and loading air fresheners, athlete's foot deterrents, etc. into the pocket, the air blown out from the insole can contain these substances, eliminating bad odors. The effect of suppressing the occurrence of athlete's foot is further enhanced.
