Description

[Detailed description of the invention] <Industrial application field> The present invention mainly relates to the improvement of a studded sole provided for athletic shoes for sports such as soccer, rugby, etc., or golf.
A shoe sole with studs that strengthens the bond between the removable shoe studs and the sole of the shoe, prevents the shoe studs from breaking, and prevents the shoe studs from falling off, making it safer for the shoe wearer to play. It is related to.

<Prior Art> Conventional shoe soles with removable and attachable shoe studs and athletic shoes equipped with the same have been designed to prevent the shoe studs from loosening around the threaded portion of the flange portion of the shoe studs. /Or a large number of small protrusions are protruded radially around the corresponding screw storage part of the shoe sole, and the screw part of the shoe stud is stored in each screw storage part of the shoe sole, and the shoe stud is released in the loosening direction. The shoe studs were removed by rotating the shoe studs in the direction of tightening or loosening the shoe studs. This studded sole or athletic shoes equipped with the same utilizes the elasticity of the sole to strongly press the sole with the stud while strongly rotating the stud in the tightening or loosening direction. The protrusions are constantly sliding in their respective rotational directions, making them susceptible to damage or abrasion due to friction.In addition, if you try to increase the height of each protrusion to prevent damage or abrasion, the elasticity of the sole will increase. It is difficult to rotate the shoe stud in the tightening direction even if you use it, and even if you can tighten it strongly, it is difficult to rotate it in the tightening direction, so it is practically impossible to do so. There was a defect.

<Problems to be Solved by the Invention> The present invention attempts to overcome the deficiencies of the conventional studded soles or athletic shoes equipped with the same as described above. The periphery of the screw part of the flange part of the shoe stud is located in a plurality of fitting recesses in front of the groove that gradually increases in depth in the tightening direction of the shoe stud around the attachment part of each screw storage device on the bottom. A plurality of protrusions provided in correspondence with each other are fitted into each other, and each protrusion of the rotating shoe stud is fitted into the fitting recess by a groove that guides each protrusion, or the groove is inserted from within the fitting recess. The object of the present invention is to obtain a shoe sole with studs that can be removed by rotating the protrusion and removing the studs.

<Example> The shoe sole with studs of the present invention, which aims to achieve the above object, consists of a shoe stud A shown in FIG. 1 and a shoe sole B shown in FIG. 2, and a shoe sole B as shown in FIG. The screw portion 2 of the shoe stud A is screwed into each screw storage device C of the shoe sole B. First, the shoe stud A has a screw portion 2 protruding from a flange portion 3 below the head portion 1, and a plurality of (two or three) pieces are fitted on the circumference at an appropriate distance from the screw portion 2. Matching recesses 4, 4 are bored, and from each of the fitting recesses 4, a groove 5 is bored, which is on the same circumference as the fitting recess 4 and becomes gradually shallower in the loosening direction (gradually deeper in the tightening direction). ,
On the other hand, fitting recesses 4 are provided at the portions corresponding to the respective fitting recesses 4 in the flange portion 3 of the shoe stud A around the screw storage device C on the contact surface A side of the sole B.
protrusions 6 that are internally fitted and have the same number as each of the fitting recesses 4;
6 is installed protrudingly. At this time, it is preferable that the bottom of each of the fitting recesses 4 be formed to be somewhat deeper than the bottom of the deepest part of each of the grooves 5. The head 1 of the shoe stud A and the sole B may be molded of hard and rigid synthetic resin.
The threaded portion of the shoe stud A may be made of metal.

<Effects of the invention> As shown in FIG. Each of the shoe studs A
When the screws are rotated in the tightening direction, the protrusions 6 around the screw storage devices C of the shoe sole B are slid inwards along the grooves 5 of the fitting recesses of the shoe studs A. Each of the protrusions 6 is fitted into each of the fitting recesses 4 and fixed. At this time, unlike conventional products, the protrusions do not rub against each other, so not only are the protrusions not worn out or damaged, but each protrusion 6 guided by each groove 5 rotates the shoe stud A. Therefore, it is easy to fit into the fitting recess 4, and once it is fitted, it will not come off easily even if the shoe stud A is subjected to an impact from the ground, so the shoe stud A will fall off and cause damage to the shoe wearer. There is no risk of the person falling down during the competition, and the head 1 of the shoe stud B, which is loosening, may be damaged by collision with the ground, etc.
There is no risk of damage. On the other hand, when removing each protrusion 6 from each fitting recess 4, similarly rotate the shoe stud A according to the groove 5 to remove each screw storage part C of the sole B.
It is easy to remove each protrusion 6 around the .

At this time, each protrusion 6 provided around each screw storage device C of the shoe B is made into a convex arc shape, and the bottom of each fitting recess 4 bored around the threaded part 2 of the flange part 3 of each shoe stud A. Since the projections 6 are formed into a concave arc shape and are bored somewhat deeper than the bottom of the deepest part of the groove 5 connected thereto, each projection 6 can be more firmly fitted into each fitting recess 4. Removal from the inside of the fitting recess 4 can be done smoothly.
