Abstract

PROBLEM TO BE SOLVED: To relieve jerking up from the ground surface at the time of walking by inserting the shaft-like part of a rivet body formed with a head part at the front end of this shaft-like part into a holding hole at the center of a washer disk and mounting a sleeve-like elastic material interposed between this washer disk and the head part to the outer peripheral part of the shaft-like part projecting from this holding hole. SOLUTION: A shoe sole 2 is internally provided with the disk-shaped washer disk 2 to be embedded therein and the holding hole 3 is bored at its center. The shaft-like part 5 of the rivet body 4 consisting of a rigid metallic material formed with the head part 6 of a slightly large diameter at the front end of the shaft-like part 5 is freely advanceably and retreatably inserted into the holding hole 3. The other end of the shaft-like part 5 is caulked and is expanded to the outer periphery, by which a stopper 7 is formed. The elastic material 8 formed of a rubber material to a sleeve shape is mounted at the outer peripheral part of the shaft-like part 5 projecting from the holding hole 3 and the elastic material 8 is interposed between the washer disk 1 and the head part 6. The holding part 3 is provided with a cap-like cover 9 fixed to the washer disk 1 so as the cover the other end of the holding hole 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip stud provided on the bottom of a spike shoe such as a golf shoe.

[0002]

2. Description of the Related Art Needle-shaped anti-slip studs projecting at a certain height from the bottom surface of a golf shoe are such that when walking on a pavement road or a club house, the ground strongly pushes up the shoe sole.
It will be difficult to walk. As shown in FIG. 5, a golf shoe tackle disclosed in Japanese Utility Model Publication No. Sho 62-19213 solves this problem by screwing a washer a to a nut g buried in the bottom surface of the shoe. b is formed, and the outer cylindrical hole b is formed.
Is provided with an overhang flange c for reducing the hole diameter, and a large-diameter key step portion e of the needle body d formed in a reverse convex shape is fitted so as to engage with the overhang collar c in the cylindrical hole b. The needle body d is urged so as to be constantly pressed downward by the tension of an elastic body f such as a coil spring provided in the cylindrical hole b. The needle body d is used when walking on a pavement road or the like. Since d is elastically depressed into the cylindrical hole b, the push-up is alleviated and walking is facilitated.

[0003]

However, as described above, in the case of a stud in which the large-diameter key step portion e of the needle body d is fitted so as to engage with the overhang flange c in the cylindrical hole b, Cylindrical hole b from the outer periphery of body d
Since the mud easily penetrates into the inside, there is a disadvantage that the needle body d does not fall into the cylindrical hole b in a short period of time and the above-described operation cannot be performed. Further, the needle body d is formed on the sliding surface of the cylindrical hole b with the inner peripheral surface.
Therefore, if the sliding surface is short, buckling is likely to occur, and there is a disadvantage in that the sliding surface is deformed and the movement is deteriorated.

[0004] Therefore, the non-slip tack of the present invention is intended to solve the above-mentioned drawbacks, and to provide a non-slip tack which can always smoothly move in and out and which can ease the thrust from the ground when walking on a paved road or the like. is there.

[0006]

For this purpose, a non-slip stud according to the present invention is provided at the center of a washer with the shaft portion of a stud body having a large diameter head formed at the tip of the shaft portion. A sleeve-like elastic body is inserted into the holding hole so as to be able to freely advance and retreat, and is attached to the outer peripheral portion of the shaft portion protruding from the holding hole so as to be interposed between the washer and the head. It is characterized by becoming.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an external perspective view of the anti-slip tack, and FIG. 2 is a longitudinal sectional view of the anti-slip tack when the shoe sole is attached. In the figure, 1 is a sole 2
A disk-shaped washer buried inside, with a holding hole 3
Has been established. Reference numeral 4 denotes a stud body made of a hard metal material having a slightly thicker head 6 formed at the tip of the shaft portion 5, and the shaft portion 5 of the stud body 4 is inserted into the holding hole 3 so as to be able to advance and retreat. ing. The stopper 7 is formed by caulking the other end of the shaft 5 and expanding the outer periphery.

An elastic body 8 formed of a rubber material in a sleeve shape is mounted on an outer peripheral portion of the shaft portion 5 protruding from the holding hole 3, and the elastic body 8 is attached to the washer 1 and the head 6. And between them. Reference numeral 9 denotes a cap-shaped cover fixed to the washer 1 so as to cover the other end of the holding hole 3.

In the non-slip stud thus configured, when the pressing force concentrates on the head 6 while walking on a pavement or the like, the elastic body 8 contracts in the axial direction as shown in FIG. Since the protruding height H from the bottom surface 2 is small, the protruding height is reduced, so that the walking is easy and the feeling is improved. In addition, in the normal state, the protrusion height H is maintained by the restoration of the elastic body 8, so that it becomes non-slip when playing on a fairway or a green.

In this non-slip stud, since the shaft-shaped portion 5 of the stud main body 4 is always covered by the sleeve-like elastic body 8, mud is hard to invade, and even if it invades, it is easy to fall down. The shape portion 5 is always held so as to be able to advance and retreat, and can exhibit the intended elastic contraction action without any trouble for a long period of time. The head 6 may of course be formed of a wear-resistant carbide tip or a material such as ceramics.

[0010] The anti-slip tack shown in FIG.
2 shows an embodiment in which the washer 1 is screwed to a nut 10 embedded in the shoe so that the non-slip stud can be detachably attached to the shoe sole 2. In this embodiment, the same parts as those in FIG. As indicated by the same reference numerals, the stud body 4 can be protruded and retracted by the expansion and contraction of the sleeve-shaped elastic body 8, and the push-up can be similarly reduced. Further, as can be seen from these embodiments, in the non-slip stud of the present invention, the holding hole 3 of the washer 1 can be made sufficiently long in the axial direction, so that the stud body 4 is stably supported straight. As a result, the strength and durability can be significantly improved without causing deformation due to buckling or poor sliding.

[0011]

As described above, according to the present invention, the uplift from the ground when walking on a pavement road or the like while wearing spike shoes is alleviated. And the durability is particularly improved.
