Description

[Detailed description of the invention] A. Field of industrial application This invention relates to shoes equipped with a safe anti-slip device.

B. Conventional technology Traditionally, to prevent shoes from slipping, the material of the bottom of the shoe has been changed or the bottom surface has been made with various unevenness, or spikes or anti-slip metal fittings have been installed in shoes for sports or mountain climbing. There is something that has been done.

C. Problems that the invention aims to solve Conventional anti-slip shoes have a limited ability to prevent slipping simply by the material and unevenness of the bottom, and the range of use of shoes for sports and mountain climbing is limited. It is almost useless on snowy roads, slopes, or mud.

The purpose of this invention is that a single pair of shoes can be used for a wide range of purposes, from sidewalks on all flat surfaces including paved roads, to mountain climbing for exercise purposes, to snowy roads, slopes, and muddy areas to prevent slipping.

D. Measures to solve the problem: A mounting plate with several holes for mounting and a curved shape similar to the place where shoes 1 are attached is provided with a slightly curved length with the upper and lower sides running horizontally. A mounting bracket 2 to which a long cylinder with a hole is fixed is provided with a non-slip pin 3 that slides up and down inside the long cylinder.

The anti-slip pin 3 has a tightening screw machined on the upper side and is sharpened on the lower side so as to sink into the ground.

The tightening screw 4 is attached to the threaded portion of the anti-slip pin 3 through an elongated hole in the long cylinder, and the anti-slip pin 3 is tightened.

The anti-slip device constructed as described above is attached to the outside of the rear part of the shoe 1, which is slightly inward, to provide a shoe with an anti-slip device.

E. Function When using the anti-slip device shoes of the present invention, when walking on a non-slip or safe path, insert the anti-slip pin 3 through the knob of the tightening screw 4 as shown in Fig. 3. Then, the tightening screw 4 is tightened and fixed at a position where the threaded portion of the tightening screw 4 enters the horizontally curved hole in the upper direction of the elongated hole drilled in the long tube of the mounting bracket 2.

The anti-slip pin 3 rises above the bottom surface of the shoe 1, and its role as an anti-slip pin 3 is excluded.

When walking on snowy roads, slopes, or muddy areas, the anti-slip pins 3, as shown in Figure 2,
Tighten at the position where the threaded part of the tightening screw 4 enters the lower curved hole. Then, the non-slip pin 3
is a pin that protrudes from the bottom and serves as a non-slip pin. The long hole drilled in the long tube is slightly bent horizontally at the top and bottom.
It is necessary to prevent the anti-slip pin 3 from loosening.

F. Example A non-slip pin 3 is inserted into a long cylinder of an iron mounting bracket 2, and a tightening screw 4 is screwed into the threaded part of the non-slip pin 3 through a long hole in the long cylinder. For 3, use case hardened material to maintain strength. At that time, a spring washer 5 may be provided between the long tube and the anti-slip pin 3.

Then, by using several holes drilled in the mounting plate of the mounting bracket 2, it is attached to the outside of the inside of the rear part of the shoe 1. The upper two pieces are fixed to the mounting plate with nuts through countersunk machine screws from inside the shoe 1, and the lower four pieces are attached using hexagonal bolts or round machine screws.

To screw in the approximately 4 hexagonal bolts or round machine screws at the bottom, a metal fitting made of iron with the required number of screws is implanted in the center of the heel of the shoe 1 during the shoe manufacturing process to maintain strength. It is attached to the threaded part of the metal fitting. Remove the sheet so that the heads of the two upper flat head machine screws do not hit your feet.

Furthermore, the shoes with anti-slip device of the present invention are for one pair and both have completely symmetrical shapes.

It should be noted that the anti-slip device is most effective if it is installed with the lower side slightly diagonally toward the front of the shoe, as shown in FIGS. 2 and 3.

G. Effects of the invention This invention is highly effective when walking on snowy roads, slopes, muddy roads, etc. due to the anti-slip pin 3, and safety has been significantly improved.

Furthermore, the present invention has the advantage that if the anti-slip pin 3 is placed upward, the shoes can be used as ordinary shoes for walking on flat ground.
