DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shank to be attached to a member constituting a shoe sole, and a shank-containing shoe.

[0002]

2. Description of the Related Art For the purpose of supporting a weight and giving a resilience to the movement of the weight to facilitate a walking operation, a shank is usually attached to the midsole of shoes. And
The conventional shank uses a highly elastic steel plate or the like, and has an elongated plate shape as a whole.

[0003]

The shank is slightly bent as a whole according to the shape of the sole. The upper surface of the sole contacting the sole is not flat, but has a curved surface as a whole. However, when the upper surface of the shoe sole is partially viewed, it is not shaped to fit the shape of the sole. For example,
The portion corresponding to the heel of the sole is almost flat due to the shank at the substantially central position inside. Therefore, when the shoe is worn, the heel of the foot, which is actually round, is forced to be flat, following the shape of the upper surface of the sole. Such a flat shape is unnatural for the heel, and there is a problem that if the shoe is worn for a long time, the heel is stressed and the foot is hurt. Therefore, an object of the present invention is to provide a shoe shank and shoes that can solve such a problem.

[0004]

In order to achieve the above-mentioned object, a shoe shank of the present invention is made of an elastic material, and a member constituting a sole of a shoe extends from a soil foot to a heel of a sole. A ring-shaped plate that has a narrow plate 1 in the front half corresponding to the base of the soil, and has a substantially oval plate formed in the rear half corresponding to the heel. A configuration characterized by having the section 2 is provided. In order to achieve the above object, the shoe of the present invention
It is made of an elastic material, and is attached to a portion corresponding to a range from a soil foot to a heel of a sole in a member constituting a sole, and a narrow plate portion 1 is provided in a front half corresponding to the soil foot. A shoe shank characterized by having a ring-shaped plate portion 2 in which a central portion of a substantially elliptical plate is hollowed in a rear half portion corresponding to the heel portion.

[0005]

[Function] The material of the sole receives the weight and therefore bends downward. However, when the shank is included, the deformation of the sole is suppressed because the shank supports the weight. In the shank 3 of the present invention, the ring-shaped plate portion 2 at the rear half is located at a position corresponding to the heel of the sole, and the load at the peripheral end of the heel is supported by the ring-shaped plate portion 2. Will not be supported by the ring-shaped plate portion 2. Accordingly, the member constituting the sole of the shoe is deformed at the inner portion of the ring-shaped plate portion 2 and is bent downward, and the upper surface of the sole is concavely curved so as to approximate the actual shape of the heel. As a result, the heel does not forcibly flatten, and can maintain a shape close to nature, and the upper surface of the shoe sole and the heel fit in a favorable state.

[0006]

1 to 6 show an embodiment of a shoe shank 3 according to the present invention. The shank 3 is formed of an elastic steel plate, has a narrow plate portion 1 in the front half, a ring-shaped plate portion 2 formed by hollowing out the center of a substantially elliptical plate in the rear half, and has a sole shape. The narrow plate portion 1 slightly swells slightly upward and slightly swells to the upper surface side, and the ring-shaped plate portion 2 has its center side lowered, that is, the inner side is lower than the outer side. , The upper surface is slightly inclined. In order to enhance the strength, a bead (groove) 4 in the front-rear direction is provided on the upper surface of the narrow plate portion 1 and a bead 5 is provided on the lower surface of the ring-shaped plate portion 2 along the periphery of the hole.

Next, FIGS. 7 to 9 show an embodiment of the shoe 6 of the present invention. The shoe 6 is manufactured by a method called a plat type or a California type, in which an upper 7 and a flexible middle plate 8 are sewn in a bag shape, and a cushion material is provided below the middle plate 8. The platform 9 is overlaid, the footbed 10 with the shank 3 attached thereon is further overlaid under the platform 9, and the sides of the platform 9 and the footbed 10 are wrapped around by the leather strap 11 integrally sewn to the upper 7, Finally, the outsole 12 is bonded below the footbed 10.

As shown in FIG. 9, the foot bet 10 is formed by joining a front half member 13 using a pulp board or the like and a rear half member 14 made of rubber. By providing a series of rising edges 15 on the upper surface of the rear half member 14 in a cup shape,
The shank 3 is embedded in the rear half member 14 made of rubber. In the shank 3 embedded in the rear half member 14 of the footbed 10, the narrow plate portion 1 in the front half corresponds to the soil foot part of the sole, and the ring-shaped plate portion 2 in the rear half is just. It is located to correspond to the heel. The shank 3 may be embedded in the foot bed 10 as described above, or may be fixed to the bottom of the foot bed 10 by a method such as bonding.

By the way, the shape of the bottom of the heel of a general last used for manufacturing shoes is almost flat, and it is impossible to use such a last when manufacturing the shoes of the present invention. Appropriate. Therefore, when manufacturing the shoe of the present invention, the bottom of the heel portion is not flat, and the ring-shaped plate portion 2 of the shank 3 is formed to have a roundness like the shape of the actual heel of the foot so as to fit. The last shall be used.

The shank 3 of the present invention can be attached not only to the platform type but also to shoes of various structures, but in order to exhibit the characteristics of the ring-shaped plate portion 2 of the shank 3 most effectively,
As in the case of the shoes of the above embodiments, by forming the sole using a flexible member such as the platform 9, a platform-type shoe having a structure in which the sole is easily deformed flexibly according to the shape of the heel is suitable. ing. And foot bet 1
It is desirable to use a shape having a cup-shaped upper surface as described above.

[0011]

The shank and shoe of the present invention are as described above. When the heel rests on the shoe sole, the heel does not forcibly become flat unlike the conventional shoe sole. Since the upper surface of the bottom is recessed inside the ring-shaped plate portion 2 of the shank 3, the heel can maintain a naturally rounded shape. Therefore, since the heel fits naturally with the upper surface of the shoe sole, it is possible to eliminate the adverse effect of the heel being hurt,
Extremely good comfort. If a member having a cup-shaped upper surface such as the above-mentioned foot bet 10 is used as a member constituting the sole, the entire upper surface of the sole is depressed and includes not only the center of the heel but also the heel circumference. The whole will fit in a rounded, natural form. Therefore, by having both the shank 3 having the ring-shaped plate portion 2 and the footbed 10 having the cup-shaped upper surface, the heel and the upper surface of the shoe sole are optimally fitted by the synergistic action thereof. Comfort is improved.
