Abstract

PURPOSE: To produce a safe and easy-to-put-on shoe which makes people tireless by changing the shape of a bucker, putting it at the insole of a shoe and thus improving the shape of the front part of the planter arch touching the soil. CONSTITUTION: A backer of a shoe is fitted almost to the shape from 10 the front part of the arch to 5 the ankle, sticked and fixed to the insole of the shoe. The outline 2 of the backer crossing the width nearby 11, almost the front part of the arch, is made to draw a curve line, rather than a direct line, towards the ankle. And by fitting and fixing this baker 1 to the insole of the high-heel shoe, the front part of the arch which finds itself among the soil facing front part of the high heel shoe, is made parallel alongside the width.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to shoes, high heel shoes,
The present invention relates to a shoe insole backer that is attached to the heel from around the arch of the insole as a reinforcing material for the shoe sole, and a high heel shoe using the same.

[0002]

BACKGROUND OF THE INVENTION The attachment of such a shoe insole backer (hereinafter abbreviated as "backer") has an important influence on the comfort of the shoe and is one of the basic components of the shoe.
That is, such a backer is attached from the front part of the arch of the insole of the shoe to the part of the heel, and is a shape retainer that plays an important role in determining the shape of the shoe sole such as the curved shape and surface shape of the shoe sole. It functions as a material. Therefore, the shape and the mounting position of the backer greatly affect the walkability or comfort of the finished shoe.

[0003]

2. Description of the Related Art By the way, a conventional backer a has a flat shape made of hard paper or leather as shown in FIGS. 7 and 8, and its contour shape b has an arch and a toe base. It is molded so as to fit the shape of the insole of the shoe from around the area between (and "the front of the arch") to the position of the heel. A contour line in the foot width direction of the front part of the arch (left side in the drawing) (hereinafter abbreviated as “front contour shape”) is curved outward (toe side) to curve c (FIG. 7) or straight line d.
(FIG. 8).

However, when shoes are manufactured by using such a conventional backer, particularly when women's pumps with high heels (abbreviated as "high heels") are manufactured, as shown in FIG. The ground contact surface e of the portion was curved in a convex shape along the foot width direction. For this reason, the ground contact surface e is not a surface contact but a point contact, and there is a drawback that it becomes unstable and unstable when wearing shoes. Due to this instability, extra force was exerted on the feet and ankles, which also caused fatigue.

Further, in high heels, the ground contact surface e is unstable, so that the person may fall and be crushed.
Most of the pedaling force on the sole of the foot was concentrated and acted on the toes, which was also the cause of hallux valgus. In this way, the unstable surface shape of the ground contact surface e not only causes fatigue of the foot,
It was an important problem, such as being unhealthy and sometimes causing sprains and other accidents.

Therefore, the present invention has been made to solve the above problems, and the shape of the ground contact surface of the front part of the arch of the shoe is improved by changing the shape of the backer and attaching it to the insole of the shoe. Accordingly, the present invention provides a backer for a shoe insole capable of manufacturing a shoe which is easy to wear, has no fatigue, and is safe, and a high heel shoe using the same.

[0007]

In order to achieve the above object, the present invention is configured as follows. In a shoe insole backer that is shaped so that its contour shape substantially conforms to the shape from the front part of the arch to the heel position of the shoe insole, and is adhered and fixed to the surface of the insole, it is approximately the front of the arch. The contour shape in the foot width direction near the position of the part is formed so as to be curved from the straight line to the heel side.

[0008] Further, this shoe insole backer is adhered and fixed in conformity with the shape from the front part of the arch to the heel position of the insole of the high heeled shoe, and the back of the high heeled shoe located in front of the arched position is joined. A high-heeled shoe is manufactured by molding the vicinity of the front part of the arch on the ground so as to be horizontal along the width direction of the foot.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific examples of a shoe insole backer according to the present invention and a high-heeled shoe using the same will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a backer of the present embodiment, and FIGS. 2A and 2B are plan views showing a main part (front contour shape) of another embodiment. FIG. 3 is a plan view showing a state in which the backer of this embodiment is attached to the insole of the shoe. FIG. 4 is a perspective view showing a state in which the backer of this embodiment is attached to a high heel shoe, FIG. 5 is a side view showing a partial sectional view of the backer, and FIG. 6 shows it from the heel to the toe. It is a back view which looked at the grounding surface direction.

The contour shape 3 other than the front contour line 2 of the backer 1 of this embodiment is formed in the same manner as in the conventional example.
Also, the material is made of hard paper, leather, or plastic as in the conventional example. The feature of the present invention lies in the shape of the front contour line 2 and is formed in a state in which the straight line 4 is curved toward the heel 5 side by an appropriate length. The amount of retreat x from the straight line 4 of the contour line 2 to the heel portion 5 side is appropriately selected depending on the shape of the bent portion 9 at the boundary between the ground contact surface 7 of the shoe 6 and the arch portion 8. Further, as a result, the shape of the contour line 2 is also a curved line shape (2, 21) as shown in FIGS. 1 and 2 (A), or a continuous curved line shape (22) as shown in FIG. 2 (B). ) Is formed.

The backer 1 having the above-described structure is a shoe 6
The shoe insole 10 is adhered and fixed so as to match the position from the front part 11 of the arch to the heel part 5. Then, the insole 10 of the shoe is flexed at the contact portion between the front contour line 2 and the insole 10 of the shoe, and the bent portion 9 is formed. At this time, both ends 2a of the front contour line 2 are adhered so as to project in the foot width direction (arrow a) of the shoe insole 10, and the central portion 2b of the front contour line 2 is retracted. Therefore, it is possible to maintain the shape in which both side portions 7a of the ground contact surface 7 near the arch front portion 11 are projected downward. As a result, the arch front part 11 of the shoe sole grounding surface 7 is formed to be horizontal with respect to the foot width direction (a).

[0012]

[Effect] Since the backer according to the present invention is configured as described above, when it is attached to the insole of the shoe, it is easy to make a habit when forming the bent portion of the shoe sole, and the shoe on the front part of the arch. The back contact surface can be formed to be horizontal in the width direction of the foot. Therefore, the ground contact surface on the toe side expands in the width direction of the foot to form a ground contact, so that a more stable shoe can be manufactured.

Further, since the ground contact surface changes from point contact to surface contact, the pedaling force is dispersed, which makes it very easy to walk, and has the effect of avoiding the concentration of weight on the toes as in the conventional case. As a result, the shoe insole backer according to the present invention has an effect that it can provide a safe and healthy shoe with less burden on the foot.
