BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of shoes, especially the insole of athletic shoes, and the insole of a shoe, and more particularly, to a function such as a function of absorbing shock generated during walking or running. The present invention relates to a structure of an insole of a shoe and an insole to be used by being inserted into a commercially available shoe.

[0002]

2. Description of the Related Art Walking or running such as so-called walking or jogging for the purpose of normal walking and health promotion of healthy persons, rehabilitation such as walking training for injured persons, and walking of physically handicapped persons (hereinafter referred to as these). At the time of walking and the like (collectively referred to as walking, etc.), it is desired to cushion the impact caused by touching the ground and protect the heel, knee, waist, and the like from the impact. Further, there is a demand for shoes that are easy to walk and that assist in walking and the like.

[0003] As a conventional means for alleviating the impact due to walking or the like, an insole or an insole of a shoe is formed by a resilient material. There are generally known ones that are configured to provide a shock while absorbing impact, and ones that are configured to spread a load by increasing a contact area at a heel portion of a shoe sole.

[0004]

[Problems to be solved by the invention]
There have been no shoes provided with cushioning means having a structure that allows a user to take a correct posture and assists when walking or the like. Further, there is a demand for shoes having a better buffering action than the conventional buffer means. Further, among the above-mentioned conventional techniques, in the one configured to increase the contact area at the heel portion of the shoe sole to distribute the load, walking or the like is performed because the load of the user is dispersed. There was a problem that it was difficult. Furthermore, among the conventional techniques, in the insole of the shoe, the arch portion does not match the internal shape of the shoe to be inserted, and an unnecessary bulge is formed to press the arch of the sole. There was a case.

[0005] It is an object of the present invention to provide a shoe insole and a shoe insole excellent in cushioning action and walking ability. Another object of the present invention is to provide a shoe provided with a cushioning means having a structure that allows a user to take a correct posture and assists when walking or the like. Another object of the present invention is to provide a shoe insole which can be easily adapted to the internal structure of the shoe to be inserted.

[0006]

In order to achieve the above object, a first aspect of the present invention is a shoe midsole provided on the upper surface of a shoe sole, which is provided from the front end of the arch to the back of the heel. Form an inclined surface so that the surface leans forward toward the end and becomes heel height,
The notch formed from the back surface to the side surface is continuously provided around the heel part, making the back surface at the heel part smaller than the upper surface, and between the upper surface of the shoe sole and the back surface peripheral side of the heel part It is characterized in that a buffer gap groove is formed.

A second aspect of the present invention is an insole to be used by being inserted into a shoe, which has a heel-height shape in which the surface is inclined forward from the front end of the arch to the rear end of the heel. The notch formed from the back side to the side surface is provided continuously around the heel part, making the back surface at the heel part smaller than the upper surface, and between the middle bottom surface of the shoe and the back side peripheral part of the heel part In the present invention, a buffer cavity groove is formed, and an abutment portion formed by notching a portion larger than the notch portion from the back surface to the side surface of the arch portion is provided adjacent to the notch portion.

The third invention is characterized in that the molding material of the insole or insole of the shoe is a synthetic resin made of an aggregate of elastic fine bubbles.

[0009]

According to the present invention, the surface of the heel part is inclined forward from the front end of the arch part to the rear end of the heel part, so that the user has a higher position of the heel part than the toe part. As a result, the entire body leans forward, so the posture is taken to stretch the back. In addition, since the center of gravity moves forward when the whole body leans forward, it becomes an aid to encourage forward movement when walking or the like, and fatigue can be reduced.

Since the notch is formed around the back surface of the heel portion, a buffer gap groove is formed, so that the elastic deformation of the heel portion when subjected to an impact is not hindered.

[0011] Further, since the back surface which receives the shock generated at the time of ground contact is smaller than the surface on which the heel portion of the user is placed,
The impact transmitted to the heel part of the user is dispersed, which can protect the heel, knees, hips, etc., and the load of the user is concentrated on the part excluding the notch on the back side, so walking Excellent,
Further, the influence of unevenness on the ground can be reduced. Further, since the front surface can be deflected using the portion excluding the cutout portion on the back surface as a fulcrum, walking or the like of the user can be assisted.

The shoe insole according to the present invention is provided with an abrasion portion so that when inserted into a shoe, it does not form an unnecessary bulge in conformity with the inside of the shoe, so that the arch of the sole can be removed. There is no oppression.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a midsole of a shoe will be described with reference to FIGS.

The midsole 12 of the present invention, as shown in FIG.
It is provided on the upper surface of the shoe sole 10a, and its structure is such that a portion from the toe portion 8 to the arch portion 2 which is substantially intermediate with respect to the entire length is formed in a thin plate shape, and the heel portion is formed from the tip of the arch portion 2 An inclined surface 7 is formed in a heel-like shape so as to gradually increase in thickness toward the rear end of the tire 1. The surface of the inclined surface 7 is desirably formed in a curved shape so as to match the shape of the sole (not shown). The height of the heel part 1 is set so that the substantial height from the toe part 8 is in the range of about 15 mm to 35 mm, and is arbitrary from this range depending on the purpose of use of the shoe and the necessary cushioning capacity. Is selected.

The heel portion 1 having such a height is shown in FIG.
As is apparent from FIG. 4 to FIG. 4, the notch 5 formed from the side wall to the lower surface so that the width in the cross section gradually decreases from the upper surface to the lower surface (see FIG. 4).
Are continuously provided around the periphery (see FIGS. 2 and 3).

By forming the notch 5 in this manner, as shown in FIG. 4, the area of the contact surface 6 with the shoe midsole 10a at the heel portion 1 of the midsole 12 comes into contact with the sole. The buffer gap groove 4 is formed so as to be smaller than the inclined surface 7 and is formed substantially U-shaped in plan view between the heel portion 1 and the upper surface of the shoe sole 10a. The cross-sectional shape of the notch 5 is
As long as the buffer gap groove 4 can be formed around the heel part 1, a linear, bulging arc, or concave arc may be used.
It can be formed in any shape.

The midsole 12 of the present invention constructed as described above.
Is formed by molding an elastic resin having fine air bubbles such as ethylene vinyl acetate copolymer, for example, and a skin 13 having air permeability is adhered to the upper surface thereof over the entire surface. .

According to the present invention, as shown in FIGS. 5 to 7, a shoe insole 11 having the same structure as the above-mentioned insole 12 is formed. 10 and can be used by laying on the insole 12a. That is, the insole 11 is formed in a thin plate shape from the toe portion 8 to the arch portion 2 which is substantially intermediate with respect to the entire length, and gradually from the tip of the arch portion 2 toward the rear end of the heel portion 1. The inclined surface 7 is formed in a heel-high shape so as to increase the thickness.
The heel portion 1 is provided with a notch portion 5 formed from the side wall to the lower surface, and is continuously provided around the notch portion 5. The notch 5 is formed so that the heel part 1 of the insole 11 is formed.
Is formed so that the area of the contact surface 6 with the insole 12a is smaller than the inclined surface 7 contacting the sole of the foot.
The buffer gap groove 4 is formed in a substantially U-shape in plan view between the upper surface of the inner bottom 12a and the upper surface of the inner bottom 12a.

The insole 11 of this invention differs from the above-mentioned insole 12 in that the abutment portion 3 is provided on the back surface of the arch portion 2. The agri portion 3 is directed from the front to back of the arch portion 2 toward the center (see FIGS. 5 and 6) so as to match the inside of the shoe 10 (see FIGS. 5 and 6), and also from the upper surface to the lower surface in the left-right cross section (FIG. 7), and is formed adjacent to the notch 5 so as to become gradually narrower from the rear surface to the side surface. By providing the edge portion 3, when the insole 11 is inserted into the shoe 10, the arch part 2 of the insole does not bulge, and therefore, the arch of the sole does not squeeze.

[0020]

According to the present invention, since the heel is inclined forward from the front end of the arch to the rear end of the heel, the position of the heel is higher than that of the toe. As a result, the user's entire body leans forward, and the user takes a posture in which the back is stretched. In addition, since the center of gravity moves forward when the whole body leans forward, it becomes an aid to encourage forward movement when walking or the like, and fatigue can be reduced.

Since the notch is formed on the periphery of the back surface of the heel portion, a buffer gap groove is formed, so that the elastic deformation of the heel portion when subjected to an impact is not hindered.

Further, the back surface which receives the impact generated when touching the ground is smaller than the surface on which the heel of the user is placed.
The impact transmitted to the heel part of the user is dispersed, and the heel, knee, waist, etc. can be protected by high buffering capacity, and
Since the user's load is concentrated on the part excluding the notch on the back side, it is excellent in walking and can reduce the influence of unevenness on the ground. In addition, the part excluding the notch on this back side Since the surface can be deflected with the fulcrum as a fulcrum, walking and the like can be assisted.
