DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole, and more particularly to an improvement in a shoe sole having no protruding heel at a portion corresponding to a heel of a foot.

[0002]

2. Description of the Related Art Conventionally, so-called heelless shoes have been on the market. Shoes without such heels are formed in a shape that is cut out diagonally upward at the rear end of the sole, since the heels as shoes do not protrude at the site corresponding to the heels of the feet. I have.

A sole used in such a conventional so-called heelless shoe has an arch supporting portion for supporting an arch of a foot, and a toe supporting portion connected to the arch supporting portion for supporting a toe side of a foot. And a heel support portion, which is provided continuously with the arch support portion and supports the heel side of the foot, and the arch support portion is formed to be the thickest, and when the toe support portion is grounded Is formed so that the heel support is separated from the ground contact surface.

That is, in a shoe without such a heel, the contact surface of the heel support portion is formed much higher than the contact surface portion of the arch portion, so that such a heel is not formed. When shoes are worn, when walking or the like, the heel support portion contacts the ground, and then the thickest arch support portion contacts the ground. In this case, the toe support portion comes into contact with the ground by swinging largely in the longitudinal direction of the shoe with the support portion serving as a fulcrum.

[0005] Therefore, in a shoe without such heels, the swinging motion in the front-rear direction of the shoe during walking is always much larger than that of a general shoe.

As a result, when the angle from the sole front end to the sole rear end is set to 15 degrees or more, when worn, the center of gravity is located in the direction of the toes of the foot, and the weight at the front end of the foot is reduced. Will support. As a result, the center of gravity moves to the toe side, and in the shoe, the fingertip may be damaged due to friction between the shoe and the inner surface of the toe leather of the shoe.

[0007] When the fingertips are constantly in friction with the inner surface of the toe leather of the shoe, the shape of the toe leather of the shoe may be deformed.

Therefore, for the above reasons, it is necessary that the angle from the front end of the sole to the rear end of the sole be 15 degrees or less.

[0009] On the other hand, when the angle from the rear end of the arch to the rear end of the sole is more than about 25 degrees,
The angle from the rear end of the arch to the rear end of the sole becomes very large, and as a result, for example, when walking,
When the sole touches the ground from the rear end of the shoe to the front end of the shoe in accordance with the form of movement of the foot, a large swing always occurs in the front-back direction of the shoe, so that a large impact always acts on the foot, It is very unstable and it is difficult to walk smoothly.

Therefore, it is necessary to form the angle from the rear end of the outer bottom to the rear end of the sole at 25 degrees or less.

As a result, in a conventional shoe without a heel, the rear end of the sole corresponding to the heel of the foot is formed in a shape that is cut out in an arc-shaped bulging upward, and is formed substantially flat. The ratio of the toe support and the arch support to the heel support formed at the rear is formed as approximately 62% to 38%, and this ratio forms the sole of a shoe without heels. By doing so, stable walking becomes possible.

[0012] When walking while wearing such shoes without heels, when the user touches the ground from the rear end side of the shoes, the ankle must be bent more, unlike the case of ordinary shoes. Therefore, each time walking, the Achilles tendon is greatly bent and stretched. Next, when the toe side of the shoe is grounded and stepped forward, since the portion corresponding to the heel of general shoes is not formed, the calf muscle, the calf front muscle of the leg and the thigh muscle are used more. Will be done.

As a result, simply walking while wearing such shoes without heels uses the muscles of the entire leg more than walking with ordinary shoes, so that jogging or the like is performed. Therefore, a predetermined amount of exercise can be secured.

Further, when the foot is advanced forward, since the user walks using the calf muscles without relying on the heel portion, the body naturally stands upright and the posture is improved.
As a result, back pain can be prevented.

As a result, since the entire foot is largely moved in the front-rear direction around the ankle, the arch of the sole of the foot is stimulated more than in the case of wearing general heeled shoes. Since it can stimulate various acupoints of the body existing on the arch, it improves the blood circulation of the whole body and also has the effect of maintaining health.

[0016]

By the way, in the conventional shoe having no heel formed as described above, the angle from the rear end of the arch to the rear end of the sole is approximately as described above. Since it is formed at 25 degrees and the angle from the front end of the sole to the rear end of the sole is formed at about 15 degrees, as a result, a very thick sole portion is formed at the arch and support portion. You.

As a result, the weight of the shoe increases due to the thick sole portion, and the cushioning property of the sole decreases due to the formation of the thick sole portion.
There was a problem that the wearer may feel tired when walking.

In addition, when the cushioning property of the shoe sole is deteriorated in this way, there is a problem that the sole cannot sufficiently absorb the impact when walking, so that various uncomfortable feelings may be felt in the feet and hips. Was.

Therefore, a technical problem of the invention described in claim 1 is that a shoe sole having no heel is applied to ordinary leather shoes and the foot is displaced in the shoes when walking. It is an object of the present invention to provide a shoe sole that does not cause deformation and does not deform the skin.

[0020]

According to the first aspect of the present invention, an arch supporting portion 59 for supporting an arch of a foot is provided.
And a toe support portion 60 connected to the arch support portion 59 and supporting the toe side of the foot, and a heel support portion 61 connected to the arch support portion 60 and supporting the heel side of the foot. ,
The arch support portion 59 is formed to be the thickest, and when the arch support portion 59 and the toe support portion 60 are in contact with the ground, the heel support portion 61 is a shoe sole formed so as to be separated from the ground contact surface. The toe support portion 60 is configured so that only the tip end thereof is grounded together with the arch support portion 59, and the arch support portion 59 is provided with a cushion portion 6.
4 and 76 are formed, and the cushion portions 64 and 76 are
The upper portion of the arch support portion 59 is formed on the inner side of the sole, and is formed of a convex portion which can be pressed against the arch, and the upper surface 81 of the shoe is joined to the convex portion, and the rear end portion of the heel support portion 61 On the upper surface side, heel stoppers 67 and 79 are formed, which are inclined toward the tip of the sole.

Therefore, according to the first aspect of the present invention,
A gap 69 is formed between the tip of the toe support 12 and the arch support 59 as in a general shoe.

Further, since the cushion portions 64 and 76 are formed, even shoes having no heels, such as ordinary shoes, are not used when the arch 59 and the support portion 59 touch the ground when walking. Since the generated shock is absorbed by the cushion portions 64 and 76 formed on the support portion 59 of the arch, the shock when the support portion 59 of the arch contacts the ground is reduced.

As a result, the invention according to claim 1 is rich in cushioning properties, and does not cause the wearer to feel tired even when worn for a long time, so that the wearer can easily walk while walking.
A shoe sole that does not cause discomfort can be applied to ordinary leather shoes.

According to the first aspect of the present invention, since the convex portion is pressed against the arch as the cushion portions 64 and 76, when the heel support portion 61 comes into contact with the ground, the arch support portion 59 comes into contact with the ground. The cushion portions 64, 7
6 absorbs the impact, so that the impact at the time of contact with the ground can be reduced.

Further, the cushion portion 6 comprising the above-mentioned convex portion
Since 4,76 always presses against the arch without contact, foot massage can be performed at the same time as walking. Further, since the skin is bonded to the convex portions as the cushion portions 64 and 76, even when the shoe does not have a heel during walking or the like, and large swinging occurs in the front-rear direction of the shoe, Of the skin 81 can be prevented.

As a result, even in the case of so-called leather shoes, the skin 8
Since the shoe 1 is not deformed, shoes having no heel can be applied to general leather shoes for men and women.

Further, according to the first aspect of the present invention, since the heel rear end portion 61 is supported by the heel stopper portions 67 and 79, it is possible to prevent the foot from being displaced during walking, and to prevent the epidermis. 81 can be effectively prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

As shown in FIG. 1, in the sole 58 of the shoe according to the present embodiment, an arch supporting portion 59 for supporting the arch of the foot, and an arch supporting portion 59 provided continuously with the arch supporting portion 59, It has a toe support portion 60 that supports the side, and a heel support portion 61 that is connected to the arch support portion 59 and supports the heel side of the foot.

The sole 5 of the shoe according to the present embodiment
8, the arch support portion 59 is formed to be the thickest, and when the arch support portion 59 and the toe support portion 60 are in contact with the ground, the heel support portion 61 is formed so as to be separated from the ground contact surface. The tip support portion 60 is configured so that the tip portion 62 is grounded together with the arch support portion 59.

The sole 58 of the shoe according to the present embodiment is similar to the soles 10, 32, 42, 4 of the shoe according to the embodiment.
Similarly to 3,45, the sole is formed by integral molding of a mold made of a synthetic resin, but the soles 10, 32, 42, 43, 4 applied to the sports shoes according to the first embodiment.
Unlike the fifth embodiment, a portion 63 corresponding to the heel of general shoes is formed on the back side of the sole 58 in the arch support portion 59. A cushion portion 64 is formed above the heel corresponding portion 63 on the surface side of the sole 58 of the arch support portion 59.

The cushion portion 64 is formed on the front surface side of the sole 58 so as to protrude in a substantially semicircular side surface.
Is formed in a cylindrical shape that contracts from the inner side portion 65 toward the outer side portion 66.

The cushion portion 64 has a substantially cylindrical gap formed therein. However, in the sole 58 of the present embodiment, no hole is formed in the outer side portion 66 of the sole. In addition, the tubular elastic body 15 or the airbag may be provided in the above-mentioned substantially cylindrical gap.

A heel support 61 is formed behind the heel corresponding portion 63 as an overhang of the heel corresponding portion 63. On the back surface side of the heel support portion 61, a cutout is formed from the heel-corresponding portion 63 so as to bulge upward, similarly to the concave portion 38 formed in the heel support portion in the previous embodiments. A recess 70 is formed.

The rear end of the heel support portion 61 is provided on the back side of the sole 58 in the same manner as the soles 10, 32, 42, 43, and 45 of the shoes in the above-described embodiments. There is provided a grounding surface portion 37 formed by notching.

A heel stopper 67 is formed obliquely at the rear end of the heel support 61 so as to extend toward the outside of the sole 58 toward the outer side 66 of the sole 58. I have.

On the other hand, unlike the soles 10, 32, 42, 43, and 45 according to the first embodiment, the toe support portion 60 is formed to be thin and has a heel-corresponding portion 63 formed on the arch support portion 59. And when the toe support part 60 is grounded, only the tip part 68 of the toe support part 60 is grounded, and between the tip part 68 of the toe support part 60 and the arch support part 59, as in general shoes. A void portion 69 is formed, and a curved portion 72 having a contour shape curved upward toward the side surface is formed between the toe support portion 60 and the arch support portion 59.

A concave portion 71 is formed on the front side of the toe supporting portion 60 so that the toe of the foot fits into the concave portion 71.

The point that a number of small holes 26 are formed in the surface of the sole 58 is the same as in the above-described embodiments.

Therefore, when the sole 58 according to the present embodiment is used for a shoe, when walking or the like, the heel support 61 is first contacted with the ground, The formed contact surface portion 37 first contacts the ground, and then the heel corresponding portion 63 constituting the support portion 59 contacts the arch. During this time, the notch 70 formed on the back surface side of the heel support portion 61 ensures an upward repulsive force, and ensures cushioning when the heel support portion 61 comes into contact with the ground.

Next, the arch 59 is contacted with the ground,
Since the cushion portion 64 is provided, the cushioning property when the heel-corresponding portion 63 provided on the back surface side of the arch portion support portion 59 is in contact with the ground is secured.

Thereafter, the toe support 60 is grounded.
Also in this case, since the curved portion 72 generates an upward repulsive force, a sufficient cushioning property is ensured even when the toe support portion 60 is grounded.

Further, the heel support 61 is provided with a heel stopper 67, which constantly supports the heel of the foot toward the front. The heel is fully supported, and the heel directly abuts the so-called counter part of the epidermis formed at the rear end of the shoe,
It is possible to prevent a situation where the shape of the counter portion changes over time.

Further, as shown in FIG. 2, in the sole, the position of the heel-corresponding portion 63 may be formed at the position of the heel of a normal shoe, and the shoe may be formed as a shoe having a general heel 74.
Other configurations of the sole 73 shown in FIG. 13 are the same as those of the sole according to the embodiment shown in FIG.

FIGS. 3 and 4 show another example in which the shoe sole according to the present invention is applied to a so-called Oxford type men's shoe made of leather.

The sole 75 of the shoe 82 according to the present embodiment.
Is basically the same in configuration as the sole 58 according to the embodiment shown in FIG. 1, but differs from the sole 58 according to the embodiment in the following points.

That is, first, the arch portion support portion 59 is formed with the cushion portion 64 formed of a substantially cylindrical void portion arranged along the width direction of the sole 58, but according to the present embodiment. In the sole 75, the heel corresponding portion 6
The cushion portion 76 provided in the upper portion of the third portion 3 is formed by a convex portion having a substantially mountain-like side surface and projecting upward from the sole 58.

The cushion portion 76 is formed so as to be highest at the outer side portion 66 of the sole 75, and the contour of the top portion 77 from the side surface portion forms a mountain shape. The skirt portion 78 of the cushion portion is formed in a substantially semicircular shape, and an inclined portion 79 is formed between the top portion 77 and the skirt portion 78. Further, a reinforcing member 80 is disposed below the top portion 77 so as to be curved upward.

The surface of the sole 75 has a heel support 6
A circular concave portion 86 is formed in 1 and a circular concave portion 86 is similarly formed in the toe support portion 60.

As shown in FIG. 4, the sole 75 according to the present embodiment has the cushion portion 76 joined to the skin 81 by means of sewing or the like.

Therefore, the sole 7 of the shoe according to the present embodiment.

It is possible to perform a smooth walk or the like without feeling an impact.

Further, the cushion portion 76 comprising the above-mentioned convex portion is provided.
However, since the foot is always pressed against the arch of the foot, the foot can be massaged at the same time as walking. Further, since the skin 81 is joined to the convex portion as the cushion portion 76, even when a large swing occurs in the shoe longitudinal direction with the heel corresponding portion 63 as a fulcrum during walking or the like,
The deformation of the outer skin 81 of the leather shoe 82 can be prevented.

As a result, even in the case of so-called leather shoes, the skin 8
Since the shoe 1 is not deformed, shoes having no heel can be applied to not only sports shoes but also leather shoes.

In this embodiment, a heel stopper 79 is formed on the upper surface of the rear end of the arch support portion 61 so as to be inclined downward toward the tip of the sole 75. Therefore, the heel stopper 79 is always
Since the foot is pressed against the heel of the foot at the rear end and the foot is supported forward of the sole 75, the foot can be prevented from shifting during walking. Therefore, when walking or the like is performed while wearing shoes without heels as in the present embodiment, the heel-corresponding region 6
Even if a large swing of the shoe in the front-rear direction occurs around the center 3, the foot can be prevented from being displaced in the leather shoe 82, and the heel stopper 79 is provided by the heel support portion 61.
