Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention forms a smooth mounting surface on the bottom surface of a shoe sole along the lateral width direction of the sole, and a mounting plate portion for abutting the mounting surface and the mounting plate portion. A metal spike having a pair of plate-like claws formed by bending both ends in the longitudinal direction on the same surface side thereof, and a nut body embedded in the sole of the shoe in a state of opening to the attachment surface side; The present invention relates to a spike mounting structure for a shoe, which is clamped and fixed to the sole through a bolt inserted into a through hole of the mounting plate portion.

[0002]

2. Description of the Related Art In a conventional shoe spike mounting structure, as shown in FIG.
0a is formed in an arc shape with a small radius, and the spike 50 is attached to the attachment plate portion 50A of the shoe sole 51.
Nut body 52 while directly contacting the mounting surface 51a of
It was fastened and fixed to the shoe sole 51 via the bolt 53.

[0003]

In this type of spiked shoe, when the pair of plate-like claw portions 50B of the spike 50 bite into the ground, a large ground reaction force is applied to each of the plate-like claw portions 50B. .. At this time, in the above-mentioned conventional structure,
The ground reaction force applied to the pair of plate-shaped claw portions 50B of the spike 50 is dispersed and received by the surface contact portion between the attachment plate portion 50A of the spike 50 and the attachment surface 51a of the shoe sole 51. Then, the ground reaction force dispersed and received by the mounting surface 51a of the shoe sole 51 is transmitted to the sole of the foot as a feeling of thrusting up. In order to reduce this feeling of thrusting up, the mounting plate portion 50A of the spike 50 is used. It is necessary to increase the contact area between the shoe sole 51 and the mounting surface 51a. However, if the front-back width of the attachment plate portion 50A of the spike 50 is increased, the movement of the phalangeal joint, which is necessary when dashing forward, becomes poor, and the attachment plate portion 5 of the spike 50 is
When the horizontal width of 0A is increased, the plate-like claw portion 50B also has a sole 51.
Since it is deviated to the outer side in the lateral width direction with respect to the lateral direction, when dashing in the lateral position to the left or right, the entire shoe must be tilted toward the dash side with one plate claw portion 50B as a fulcrum with a large motion. However, the movement becomes worse by that amount. Therefore, there is a limit to increasing the contact area between the mounting plate portion 50A of the spike 50 and the mounting surface 51a of the shoe sole 51, and it is difficult to reduce the feeling of thrust. The present invention has been made in view of the above circumstances, and an object thereof is to push up due to a ground reaction force at a spike mounting location while keeping the facing distance between both plate-shaped claw portions of the spike the same as the conventional one. The point is to reduce the feeling.

[0004]

In order to achieve the above object, in the shoe spike mounting structure according to the first aspect of the present invention, each of the bent portions of the spike has the above-mentioned construction. The mounting plate portion and the plate-like claw portion are both arranged in an inclined posture that intersects with each other, and between the mounting surface of the shoe sole and the mounting plate portion of the spike, contact the outer surfaces of the respective bent portions in the inclined posture. It is characterized in that an elastic cushioning member having a corresponding inclined receiving surface is interposed. Further, in the spike attachment structure for a shoe according to the second aspect of the present invention, each of the bent portions of the spike is formed in an inclined posture that intersects both the attachment plate portion and the plate-like claw portion, and the shoe is provided. Between the bottom mounting surface and the spike mounting plate portion, there is interposed an elastic buffer member having an inclined receiving surface capable of contacting the outer surface of each of the bent portions in the inclined posture, and the inclination receiving member of the elastic buffer member is interposed. Small voids are formed between the surface and the opposing surface of the bent portion of the spike, respectively.

[0005]

According to the first aspect of the present invention, when a large ground reaction force is applied to the pair of plate-shaped claw portions of the spike, the ground reaction force is generated between the spike mounting plate portion and the shoe sole mounting surface. At the same time as it is dispersed and received by the surface contact part, component force is generated in the vertical direction side to the outer surface of the bent slope part of the spike at the contact part between the outer surface of the bent part of the spike tilt position and the inclined receiving surface of the elastic cushioning member. However, the component force is dispersedly received by the mounting surface portion of the shoe sole located laterally outside the mounting plate portion of the spike through the inclined receiving surface of the elastic cushioning member. The second aspect of the present invention
According to the claim, when a large ground reaction force is applied to the pair of plate-like claw portions of the spike, the ground reaction force is dispersed and received by the surface contact portion between the spike mounting plate portion and the shoe sole mounting surface. At the same time, the spike serves as a fulcrum at the bending boundary portion between the mounting plate portion and the bent portion within the range of a small gap formed between the inclined receiving surface of the elastic cushioning member and the outer surface of the bent portion in the inclined posture. As a result, it elastically deforms toward the widening angle side. When the outer surface of the bent portion in the inclined posture of the spike comes into contact with the inclined receiving surface of the elastic cushioning member due to the elastic deformation of the spike, a component force is generated in the direction perpendicular to the outer surface of the bent portion of the spike, and the component force is elastic. Through the inclined receiving surface of the cushioning member, the spikes are distributed and received by the mounting surface portion of the shoe sole located laterally outside of the mounting plate portion.

[0006]

Therefore, according to the first aspect of the present invention, the ground reaction force applied to the pair of plate-shaped claw portions of the spike can be dispersed and received in a wider area than the mounting area of the mounting plate portion. As a result, it is possible to reduce the feeling of thrusting up due to the ground reaction force at the spike mounting location. Further, according to the second aspect of the present invention, not only the ground reaction force applied to the pair of plate-shaped claw portions of the spike can be dispersed and received in a wider region than the mounting area of the mounting plate portion, but also the spike can be received. Since the impact can be mitigated also by elastically deforming to the angle-increasing side at the bending boundary portion, it is possible to further reduce the feeling of thrusting due to the ground reaction force at the spike attachment point.
