Abstract

PROBLEM TO BE SOLVED: To enable more stable kick action preventing the heel from slipping by putting a heel block less higher than heel points onto the outer edge of the rear of the heel on the shoe bottom. SOLUTION: A heel block 5 having a projection 6 is applied onto an outer edge 4 of the rear at the heel of an out sole body 1 having several points 2 on its bottom. The heel block 5 having a shape of boat bottom is put on over from the front part to the end of the outer edge 4 of the rear of the heel and has an inner slant edge 7 cut downward to the out sole body 1 as shown on the sketch. This inner slant edge 7 serves to keep stable the kick action until it finishes preventing the heel from slipping off concurrently the heel block 5 being buried into the ground holds the pressure from it when the heel outer edge 4 is placed. The projection 6 to put on the surface of the heel block 5 might be one as well as several as it serves to keep stable the turning round movement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field relating to shoe soles used in soccer shoes, and provides slip resistance and stability of an axial foot during an action during a soccer game, particularly during a kick action. It relates to the soles of soccer shoes that can be dramatically improved.

[0002]

2. Description of the Related Art Conventionally, a plurality of cylindrical points are provided on the sole of a soccer shoe from the vicinity of the toe portion to the heel portion on the bottom surface of the sole for the purpose of improving anti-slip properties during competition. . The height of the point is about 5 mm to 10 m
Although it is about m, the point provided on the heel part is relatively long, about 15 mm, in order to maintain the forward leaning posture during the competition.

[0003]

[Problems to be Solved by the Invention] Speaking of the foot, a soccer game is a sport that involves various motions such as running motions, direction changing motions in the front-rear and left-right directions, and kick motions.
In particular, in kicking, it is necessary to kick the ball in various postures such as kicking forward and kicking laterally while changing direction. In the conventional soccer shoes, the points are provided almost vertically to the bottom surface of the shoe sole, so that the grip force can be exhibited without any particular problem in running operation and kicking operation forward.

However, when attempting to kick the ball to the side while changing direction, it is necessary to step the axial foot toward the ground from diagonally above, and at the same time, twist the state and kick in the target direction. Since the direction is different from the target direction, it is necessary to rotate the toe toward the target direction with the heel rear end instep side of the shaft foot as the axis.

In this case, in the conventional sole of a soccer shoe, two to five shoes are provided in a direction substantially perpendicular to the bottom of the heel.
Only about this number of points are provided, and since these points are relatively long, about 15 mm, they do not properly stick to the ground. Therefore, there is no choice but to perform the above-mentioned rotational movement around the periphery of the shoe sole on the outer instep side of the heel rear end where there is no point, and the kicking operation is performed in an unstable state where the grip force is almost ineffective. Therefore, it was a cause of careless slip.

[0006]

[Means for Solving the Problems] Therefore, in order to solve the above problems, various movements of spike shoes in a soccer game are analyzed, particularly kick movements accompanied by a direction change are analyzed to determine the structure of the rear end of the heel. Invented. That is, the foot pressure distribution map determining means determines the foot pressure distribution map based on the data obtained by the foot pressure distribution history measuring means, in the direction and area of action of the shear stress acting on the sole in the kick motion accompanied by the direction change. decide. The obtained foot pressure distribution chart shows the distribution of the area where the foot pressure is applied due to the relationship between the shoe sole and the road surface when performing the kick motion. According to the foot pressure distribution map obtained by the above method, on the heel rear outer side of the bottom of the shoe sole,
By providing a pedestal part that protrudes from the bottom of the shoe sole and whose height is lower than the heel part point, inadvertent slippage of the heel part is prevented during kick motion accompanied by direction change, and stable kick motion is possible. be able to. Furthermore, by providing at least one protrusion on the upper surface of the pedestal portion, it is possible to exert a better grip force against the rotational movement of the toe portion around the heel rear end outer side toward the outer side. Is possible.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Here, the foot pressure distribution history measuring means is operated by a subject wearing a shoe having a relatively flat sole design on a plate type sensor, and the sole is in contact therewith. In the area of the plate type pressure sensor, a distribution of vertical compressive stress is measured as foot pressure distribution data for each minute unit time, and is stored in a predetermined storage medium via a processor.

When the subject walks on the plate type sensor, the foot pressure distribution in the ground contact area of the shoe sole is 1/10 seconds or 1
It is measured every 100 seconds and recorded as foot pressure distribution data and load vector data.

Based on the foot pressure distribution map determined in this way, a pedestal that protrudes from the bottom of the sole of the bottom of the bottom of the bottom of the bottom of the shoe of the soccer shoe and is higher than the point of the heel. Part was set up. The pedestal may be formed integrally with the shoe sole body when the shoe sole body is formed by the injection production method, or only the pedestal is formed separately in advance and the shoe sole body is formed by the injection production method. It may be placed in a mold during molding and fixed integrally with the sole body. Further, it is possible to fix the shoe sole body and the pedestal, which are separately molded, to each other by an adhesive agent or a rivet.

Further, the protrusion provided on the upper surface of the pedestal portion is on the outer rear side of the heel rear end portion based on the foot pressure distribution chart,
Only one part may be provided so that the portion where the pressure is most concentrated becomes the axis of the rotational movement of the toe portion, or it moves along the peripheral portion on the outer rear side of the heel rear end portion with the rotational movement of the toe portion. It is also possible to provide a plurality to correspond to the rotating shaft. In any case, these protrusions do not exert the gripping power inherent in a soccer shoe, but are merely for stabilizing the rotational movement around the pedestal. It does not have to be as large as the point where a plurality of points are provided over.
