Abstract

PROBLEM TO BE SOLVED: To prevent even a spike of screwing type from loosening by forming a flange seat part obtained by raising the upper surface of a flange part to abut or a spike fixing part on the surface of a sole of shoe. SOLUTION: The flange seat part 30 obtained by raising the upper surface of a flange part to abut is formed at a spike fixing part on the surface of the sole of shoe 12 integrally with the sole of shoe 12. This part 30 is in the state of a mound which is circular by a plane view and is nearly a segment in its cross section and its peripheral part 32 is at a position recessed compared with the surface 34 of the sole of shoe 12 and is raised to become higher from this part 32 toward its center. The surface of the part 30 is substantially abutted on the whole of the upper surface of the part 10 when the spike 2 is fastened. It is desirable to bury a seat body 14 deeply in the sole of shoe by an interval distance. By giving the compressing margin of the elastic sole of shoe of a distance portion to the center of the part 30, loosening of the spike is advantageously prevented in combination with the entire raised shape of the part 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sports shoe having a non-slip spike such as a golf shoe on a sole thereof.

[0002]

2. Description of the Related Art In sports shoes, particularly golf shoes, having a non-slip spike, a screw-in spike as shown in a sectional view in FIG. 4 is usually used as the non-slip spike. The spike 2 is formed by a tapered substantially conical column pin 4 and a cylindrical mounting stem (mounting shaft) 8 having an outer thread 6 formed on an outer peripheral surface thereof via a flange 10 having a circular shape in plan view. It is constructed continuously. The flange 10 is formed in a hat shape having a substantially arc-shaped cross section, in which the surface (lower surface) on the pin 4 side is convex and the surface (upper surface) on the stem 8 side is concave. The columnar pin 4, the mounting stem 8 and the flange 10 are concentric.

On the other hand, the sole (pedestal) 1 is provided on the sole 12.
4 are buried in advance. The seat body 14 includes a headed cylindrical tube portion 16 and a circular flange 18 formed at the upper end of the tube portion 16 for preventing the shoe from falling off the sole.
The inner screw 20 is formed on the inner peripheral surface of the.

[0004] When attaching the spike 2 to the shoe sole 12, the tip of a mounting jig (not shown) is inserted into a pair of jig insertion holes 22 provided in the flange 10 of the spike 2. The spike 2 is tightened by screwing the mounting stem 8 into the cylindrical portion 16 of the sheet member 14 while rotating the spike 2 using a mounting jig. The spike 2 and the sheet 14 are usually integrally formed of metal, synthetic resin, ceramics, or the like.

[0005]

However, in the above-mentioned sports shoes using the screw-type spikes, while the shoes are used, the screw portions of the spikes are loosened and the spikes easily fall off from the shoe soles. In particular, at the beginning of use of the shoe, there was a problem that the screw portion of the spike was easily loosened. Therefore, the player often needs to check the spikes while holding the mounting jig, and if a spike is loose, the spike must be retightened, which is troublesome. In addition, the spikes often do not loosen after several times of tightening the spikes, but if the spikes are forgotten or neglected to check for looseness, the loosened spikes will fall off and be lost, resulting in a new spike. Procurement,
It is necessary to remove the mud clogged in the sheet body, which may cause unexpected cost and labor.

The reason why the spikes are loosened as described above is considered to be as follows. That is, in a state where the spike 2 is screwed onto the sheet body 14 embedded in the shoe sole, the flange portion 10 applies pressure to the surface of the shoe sole (usually made of rubber or rubber-like elastic material), and the sheet generated by this pressing is applied. Body 14
The spike 2 is fixed by the frictional force between the inner screw 20 of the mounting stem 8 and the outer screw 6 of the mounting stem 8. A space 24 is formed between the tip (upper end) of the mounting stem 8 and the bottom (innermost part) of the cylindrical portion 16 of the sheet member 14. Since the flange 10 of the spike 2 has a curved shape bulging toward the pin 4, pressure is mainly applied to the shoe sole by the peripheral edge of the flange 10. For this reason, the sole (the flange 10
(A portion in contact with the peripheral portion of the spike 2) is substantially generated, and as a result, the tightening of the spike 2 is loosened.

The present invention has been made in view of the above-mentioned circumstances, and provides a sports shoe which can prevent the spike from becoming loose when the shoe is used, even when a screw-type anti-slip spike is used. The purpose is to do.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a sports shoe having a spike formed on a shoe sole and having a columnar pin and a mounting stem connected via a flange portion. A sports shoe characterized in that a flange seating portion which is raised so that the upper surface of the flange portion comes into contact with the spike mounting portion is formed.

When a conventional screw-type non-slip spike is screwed into an elastic sole of a sports shoe, a pressure is applied to the surface of the sole with the periphery of a brim portion curved in a hat shape, thereby fixing the spike. However, as described above, particularly in the early stage of use of the shoe, the pressed portion of the shoe sole is easily deformed by compression, which results in loosening of the spike. On the other hand, in the sports shoe of the present invention, the spike mounting portion on the shoe sole surface is formed with the flange seating portion raised so that the upper surface of the flange portion of the spike is in contact with the spike. It can be received by the entire flange seating portion, so that the portion pressed by the flange portion is unlikely to be deformed or set, and as a result, the loosening of the spike is effectively prevented.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 is a sectional view showing a spike mounting portion of a sports shoe (golf shoe) according to a first embodiment of the present invention. In the shoe of the present example, a flange seating portion 30 that is raised so that the upper surface of the flange portion 10 of the spike 2 comes into contact with the spike attachment portion on the surface of the shoe sole 12 is formed integrally with the shoe sole 12. The flange seating portion 30 has a mound shape (small mountain shape) having a circular shape in a plan view and a substantially arcuate cross section, and its peripheral edge portion 32 is
It is located at a position depressed from the surface (lower surface) 34 of No. 2 and rises from the peripheral portion 32 so as to increase in height toward the center (the direction of the center line XX). When the spike 2 is tightened, the surface of the flange seating portion 30 substantially contacts the entire upper surface of the flange portion 10. Since the spike 2 and the sheet body 14 used in the present example are the same as those shown in FIG. 4, the same reference numerals in FIG. 1 denote the same parts as in FIG. Omitted.

FIG. 2 is a partially enlarged view of a portion on the right side of the center line XX of the spike mounting portion shown in FIG. In the shoes of the present embodiment, it is preferable that rp ≧ rs when the radius of curvature of the upper surface of the flange 10 of the spike 2 is rp and the radius of curvature of the surface of the flange seating portion 30 is rs. Further, it is appropriate that rp = 6 to 15 mm and rs = 5 to 14 mm. In this example, rp = 12 mm and rs = 11
mm.

The height h of the flange seating portion 30 is h = 1 to 4 mm.
It is appropriate that h = 2 mm in this example.
Further, the depth of the depression where the peripheral edge portion 32 of the flange seating portion 30 is located, that is, the peripheral edge portion 32 of the flange seating portion 30 and the shoe sole surface 34
It is appropriate that the distance k with respect to k = 1 to 4 mm, and in this example, k = 2 mm.

The sheet member 14 is provided at the front end (lower end) of the cylindrical portion 16.
The sole 12 is located at a position which is retreated into the sole 12 by a distance d from the raised surface (lower surface) of the flange seating portion 30.
In other words, it is preferable that the sheet member 14 is buried deep in the shoe sole by the distance d. By providing the compression allowance of the elastic body (shoe sole) for the distance d to the center portion of the flange seating portion 30 in this way, in combination with the overall raised shape (mound shape) of the flange seating portion 30, Spike loosening can be more advantageously prevented. The distance d is d =
0.5 to 2 mm is appropriate, and in this example, d =
1 mm.

[Second Embodiment] FIG. 3 shows a second embodiment of the present invention.
Sports shoes (golf shoes) according to the embodiment
It is sectional drawing which shows the spike attachment part of FIG. The shoe of this example has no depression for providing a collar seating portion on the sole 12,
It is the same as the shoe of the first embodiment except that the peripheral edge portion 32 of the flange seating portion 30 is at the same height position as the shoe sole surface 34. Therefore, in FIG. 3, the same portions as those in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted. Further, the curvature radius rp of the upper surface of the flange portion 10 and the flange seating portion 3 described above.
The curvature radius rs of the zero surface, the height h of the flange seating portion 30, and the retreat distance d of the seat body 14 into the shoe sole are the same as those in the first embodiment, and therefore, the description thereof is omitted.

In the shoe of the present embodiment, the seat 14 for attaching the spike 2 is buried shallowly in the shoe sole 12, that is, shallower than the first embodiment by a length corresponding to the depth of the depression. Since it can be buried, there is an advantage that the shoe sole can be made thinner as compared with the first embodiment.

In the sports shoe of the present invention, the sole may have a single-layer structure, a two-layer structure including an inner layer and an outer layer in contact with the ground, or a multilayer structure having three or more layers. When the shoe sole has a single-layer structure, as the material of the shoe sole, for example, an elastic foam such as foamed rubber or foamed plastic, or non-foamed rubbers and plastics can be used. In addition, two
In the case of a layer structure, as the material of the inner layer, for example, foamed rubber, elastic foam such as foamed plastic, non-foamed rubbers and the like can be used, and as the material of the outer layer,
Rubber or rubber-like elastic materials can be used.

Also, the sports shoes of the present invention are not limited to the above embodiment. For example, in the above embodiment, the surface of the flange seating portion is made smooth, but the surface of the flange seating portion has irregularities. It may be provided. Further, other configurations may be variously changed without departing from the gist of the present invention.
