Abstract

PURPOSE:To prevent shoes from unexpectedly coming off during walking. CONSTITUTION:An insole is composed of an outer surface layer 11 and a rear surface layer 12, and is adapted to be set at least in the front part of the inner bottom wall 15 of each of shoes 14. The outer surface layer 11 has water- permeability and elasticity, and is therefore made of, for example, synthetic paper. Sweat permeates the outer surface layer, and is then absorbed and retained in the rear surface layer. Accordingly, it is possible to always prevent sweat from sticking to the outer surface layer which is therefore held in a fresh and highly frictional condition. Thus, a foot is prevented from slipping forward with a shoe so as to form a large gap in the heel part, thereby it is possible to prevent the shoe from unexpectedly coming off during walking.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is laid on the inner bottom surface of a shoe,
The present invention relates to an insole member for a shoe that prevents the shoe from being accidentally removed during walking.

[0002]

2. Description of the Related Art Conventionally, in order to prevent the shoe from coming off during walking, an insole member is additionally laid inside the shoe. The most common insole member is to narrow the inside of the shoe simply by the thickness of the insole member. If you use this, you will naturally be cramped. In addition, an insole member in which unevenness is formed to match the sole surface of the foot is also known.
If this is used, it is possible to prevent the careless removal without making the user feel cramped. However, the shape of the sole of the foot is different for each person and for the left and right sides of the same person, and since the shape changes due to movement and moves within the shoe, the unevenness of the insole member and the foot are not necessarily the same. It does not always engage, so
The effect of preventing this coming off is not sufficient.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an insole member which can prevent the shoe from coming off during walking while allowing a space in the shoe so as not to be cramped. It was done.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a surface layer made of a material such as foamed rubber that has water permeability that allows sweat to pass therethrough and has elasticity that dents a finger portion, and the surface layer is bonded to the surface layer. An insole member for a shoe, which comprises a back surface layer made of a material such as synthetic paper having a water absorbing property capable of absorbing and retaining sweat, and which can be provided on at least a front portion of an inner bottom surface of the shoe.

Further, the present invention is the above-mentioned, wherein the surface layer is
It includes an insole member of a shoe, which is made of non-water-absorbent foamed raw rubber that repels sweat.

The present invention further includes the insole member having an adhesive on the back surface of the back surface layer.

[0007]

The present inventor has paid attention to the fact that when the shoe is new, it is unlikely that it will come off during walking, and that it will be easy to take off when used. This is because if you get used to it, the front part of the inner bottom of the shoe becomes slippery due to sweat, and when you kick out, your foot moves forward in the shoe, leaving a gap in your heel.

The above-mentioned structure of the present invention prevents such a phenomenon from occurring. That is, the sweat on the back of the foot passes through the surface layer and is absorbed by the back surface layer, so that the surface layer is always kept dry. Further, the surface layer is made of a foam material and is dented according to the toes of the toe, and the friction is large. Therefore, the forward movement of the foot is prevented when kicking out while walking, and a large gap is not formed in the heel portion, so that the shoe does not come off.

[0009]

EXAMPLES Hereinafter, examples illustrating the present invention will be specifically described.

The insole member 10 has a back surface layer 11 joined to a back surface layer 11 and an adhesive 13 provided on the back surface of the back surface layer 12. It has a shape that can be placed on the front.

The surface layer 11 is made of a material having water permeability that allows sweat to pass therethrough, non-water absorptivity that does not absorb sweat, and elasticity that easily dents when pressed by a toe. For example, open cell foamed raw rubber may be used. This thickness is suitably 1 to 5 mm, and particularly about 3 mm is easy to use. Also, the size of the bubbles should be approximately 0.05 to 2 mm, and especially 0.2 to
When the thickness is about 1.0 mm, it is preferable because when it is used for women's shoes, it penetrates the stockings and comes into direct contact with the skin, and a larger friction force is obtained.

The back surface layer 12 is made of a water-absorbing material capable of absorbing and retaining sweat. For example, a non-woven fabric or woven fabric made of paper, synthetic paper, cotton or the like, or a polymer water-absorbing agent is used. Can be used. This thickness is arbitrary,
It is good to set it to about 0.2 to 1 millimeter. It is desirable that this hardness is not so hard in terms of comfort.

Any adhesive can be used as the adhesive 13, but it is convenient to use one with a release paper. Further, as will be described later, since the insole member 10 is disposable, it is suitable that the adhesive force is weak so that it can be easily peeled off.
Naturally, it must have heat resistance so that it does not melt at body temperature.

The insole member 10 is used as follows.

As shown in FIG. 1, the shoe 14 is attached to the front part of the inner bottom surface 15 of the shoe 14 with an adhesive 13. In this state, shoes 1
When wearing 4 and walking, the fingers 17 of the foot 16 become to bite into the surface layer 11 when kicking out, that is, when applying a force to the toes, and do not move forward in the shoe 14, and Since it does not create a large gap in the heel, it does not come off accidentally.

Even if the sweat is continued to be used, since the sweat penetrates the surface layer 11 and is retained by the back surface layer 12 and does not accumulate on the surface layer 11, the above effect is maintained. When the sweat accumulated on the back surface layer 12 reaches the limit, the insole member 10 is peeled off and replaced with a new one. Although depending on the degree of use, one insole member can be used for about 1 to 6 months.

In the above example, the shoe is located only on the front part of the insole, but it goes without saying that it may cover the entire insole. Furthermore, although the surface layer is made of a non-water-absorbing material in the above example, if the back surface layer has a strong water-absorbing property, a material having a weaker water-absorbing property can be used. Needless to say, a non-water-absorbing material is preferable. Further, in the above example, the shoe is attached to the insole by adhesion, but other means may be used, for example, if it covers the entire insole, it may be simply placed. It suffices if it can be fixedly provided.

[0018]

As described above, in the insole member of the present invention, the surface layer is always kept in a fresh, high friction state where sweat does not adhere, so that the foot advances in the shoe during walking. It is possible to prevent it from being accidentally removed. In addition, the surface layer has elasticity and is recessed so that the toes of the toes bite into it, so the above-mentioned detachment prevention effect is further strengthened, and at the same time, since the movement of the fingers is not hindered, the feel is improved and it becomes less tired . Of course, since the front part of the foot is not tightened, it is not cramped and a comfortable layering feeling can be obtained.

In particular, when the surface layer is made of a non-water-absorbing material,
The action of transferring sweat to the back surface layer works more effectively, and the surface layer can be kept in a fresher and higher friction state.

If an adhesive is provided on the back surface of the back surface layer, the insole member can be easily replaced.
