Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an anti-slip device for shoes that prevents the user from falling when walking on an icy snowy road or a snowy road surface.

(Prior Art) As shown in FIG. 5, a conventional anti-slip device for shoes includes a recess c that communicates with the arch portion h of a rubber shoe sole a, and a recess c that communicates with the arch portion h, as shown in FIG. Both sides of the proximal end of the spike fitting e, which has claws d formed therein, are supported by spike support fittings f and are rotatably mounted, and when in use, the claw d at the tip protrudes from the ground surface of the heel part b as shown in the figure. When not in use, the spike fitting e is rotated in the direction of the arrow so that the claw d at the tip is positioned at the arch portion h of the shoe.

(Problem to be solved by the invention) However, in the above-mentioned conventional shoe anti-slip device, when the spike fitting e is rotated, the rear end of the spike fitting e directly touches the surface of the recess c of the heel part b. Since it rotates while being pressed, the pressing sliding surface is significantly worn, and as a result, the spike fitting e does not rotate smoothly and the spike fitting e
It is not possible to stably maintain the used and unused states over a long period of time, and there is a disadvantage that loosening occurs in a short period of time, causing rattling.
Since the spike fittings e were made of metal, there were problems such as the rattling that caused noise when walking.

In addition, since the tip of the spike fitting e is located at the arch portion h when not in use,
This is inconvenient when an object comes into contact with the arch portion h.

The present invention was developed with an eye to the above-mentioned problems.It prevents wear, ensures smooth rotation over a long period of time, and allows a member corresponding to a spike fitting to protrude from the arch of the foot. To provide an anti-slip device for shoes which rotates without any slippage and ensures stable retention when used as an anti-slip device and stable retention when not in use.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an anti-slip device for shoes with two pressing projections on the top and bottom of the rear end of the arm 1.
A head 5 has pivots 3 protruding horizontally on both sides at a position displaced from the pressing ridge 2 toward the tip, and a spike stud 4 erected on one side of the tip. A spike body 6 made of a hard and tough thermoplastic synthetic resin integrally formed with the spike body 6, a used state storage recess 21 in which the spike body 6 is stored when in use, and an unused state storage recess 22 in which it is stored when not in use. a shoe sole 9 having a rubber heel portion 8 with a recess 7 formed therein; and a spike support member 10 that pivots the pivot 3 of the spike body 6 and is fixed within the recess 7 of the sole 9. and slits 1 with one end open at intervals equal to or less than the length of the pressing protrusion 2.
An elastic piece 13 is formed in a cantilevered state by forming an elastic piece 2, and is located between the spike body support member 10 and the inner surface of the recess 7 of the sole 9, and presses the pressing ridge 2 of the spike body 6. The plate 11 is made of a hard thermoplastic synthetic resin and is disposed at a position where the resilient piece 13 is pressed.

(Function) When the above-mentioned anti-slip device for shoes of the present invention is used, when walking on an icy or snow-covered road surface, that is, when in use, the spike body 6 is placed in such a state that the spike studs 4 of the head 5 protrude from the sole 9. When not in use, the spike body 6 is rotated about its pivot 3 and stored in the concave part 7 together with the spike stud 4 for use.

In this case, when the spike body 6 is in use or not in use, the pressing ridge 2 formed at the rear end of the arm 1 at a position slightly displaced backward from the pivot 2,
The resilient piece 13 of the hard thermoplastic synthetic resin plate 11 pressed by this pressing ridge 2 and the pressing restoring force of the rubber constituting the heel portion 8 act to bring the head 5 of the spike body 6 into the used state. It comes to be pressed against the bottom surface of the storage recess 21 or the unused state storage recess 22. Furthermore, when the spike body 6 is rotated about the pivot 3, the pressing flange 2 is moved by the resilient piece 13.
It will slide while pressing the top.
