Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to an anti-slip fitting for shoe soles used when walking on frozen roads.

(Prior art) Conventionally, according to Utility Model Publication No. 16082/1982, the lower part is positioned on the lower surface of the board via a spring, and the upper part slidably passes through a hole provided in the board to attach the board. a support shaft protruding from the upper surface; supported by the support shaft so as to be rotatable in horizontal and vertical directions with respect to the substrate;
An anti-slip device for shoes has been proposed that includes an anti-slip metal fitting with claws around the anti-slip metal fitting.

This type of anti-slip device for shoes can be used by flipping the non-slip metal fittings inside out at the same location, which is convenient as it allows the installation area of the non-slip metal fittings to be reduced, but the non-slip metal fittings are made up of a single piece. Therefore, the anti-slip effect was insufficient depending on the frozen state of the road surface.

(Problem that the invention aims to solve) This invention uses two-stage anti-slip metal fittings to further improve the anti-slip effect by using various combinations of anti-slip metal fittings depending on the frozen state of the road surface. It is something that we try to improve.

(Means for solving the problem) This invention will be explained below with reference to the actual drawings.
This idea consists of a substrate 1, a lower portion of which is positioned on the lower surface of the substrate 1 via an elastic body 21, and an upper portion of which is slidably inserted through a hole 11 provided in the substrate 1 and presses against the upper surface of the substrate 1. A protruding support shaft 2, a non-slip fitting 3 which is rotatably supported by the supporting shaft 2 in the horizontal and vertical directions with respect to the substrate 1, and has claws 32 on its periphery, and an upper part of the non-slip fitting 3. The non-slip metal fitting 4 is rotatably supported by the support shaft 2 in the horizontal and vertical directions independently of the non-slip metal fitting 3 relative to the substrate 1, and has a claw 42 on the periphery thereof. The gist of the invention is an anti-slip metal fitting for shoe soles characterized by the following characteristics.

In this invention, the elastic body 21 is composed of a coil spring, a plate spring, rubber, etc.
1 is inserted into the lower part of the support shaft 2 on the lower surface of the substrate 1, is interposed in a compressed state between the washer 22 attached to the lower end of the support shaft 2 and the lower surface of the substrate 1, and protrudes from the upper surface of the substrate 1. Anti-slip fittings 3, 4
A constant tensile pressure is applied to the upper part of the support shaft 2 supporting the substrate 1, and the rotating shafts 31 and 41 of the anti-slip fittings 3 and 4 supported by the support shaft 2 are brought into pressure contact with the upper surface of the substrate 1, thereby preventing the board from sliding. The stoppers 3 and 4 are held in an open state or a closed state. Anti-slip fittings 3
and 4 are fitting grooves 241, 241 and 251 respectively formed in washers 24 and 25 which are rotatably supported on the support shaft 2 between the flange 23 at the upper end of the rotatable support shaft 2 and the upper surface of the substrate 1. 251, a rotating shaft 3 formed opposite to one end of the non-slip fittings 3 and 4;
1, 31 and 41, 41 are fitted into bearings to be supported on the support shaft 2.

As shown in FIG. 3, the anti-slip fitting for shoe soles of this invention constructed as described above has a recess 51 in the stepping part or heel part, and a support shaft 2 at the center of the recess 51.
It is used by being fixed by rivets or the like to a shoe sole 5 which has a housing chamber for the elastic body 21 and washer 22.

(Function of the device) Since this device is constructed as described above, when walking on a frozen road surface, the anti-slip fittings 3 and 4 can be opened at the rear of the sole 5 as shown in FIG. position and expose the claws 32 and 42 formed on the non-slip fittings 3 and 4 to the ground surface, or move the non-slip fittings 3 and 4 vertically forward by 90 degrees from the state shown in FIG. Rotate it to stand up, then rotate it horizontally 180 degrees, and then vertically forward 90 degrees to open the anti-slip fittings 3 and 4 at the front of the sole 5, as shown in Figure 4. position and expose the claws 32 and 42 formed on the non-slip fittings 3 and 4, respectively, on the ground surface, or move only the non-slip fitting 4 vertically forward 90 degrees from the usage state shown in Fig. 3. rotate it,
Further rotate the shoe by 180 degrees in the horizontal direction, and further rotate it forward by 90 degrees in the vertical direction, and as shown in FIG. Alternatively, in the operating state shown in Fig. 4, the anti-slip fitting 4 can be rotated 90 degrees backward in the vertical direction to stand up, then rotated 180 degrees horizontally, and then used in the vertical direction. Rotate backward 90 degrees to position the anti-slip metal fittings 3 toward the front of the sole 5 and the anti-slip metal fittings 4 toward the rear of the sole 5 in an open state, as shown in Figure 6, for use. I can do it.

In addition, when walking on a normal road surface that is not frozen, the anti-slip metal fittings 3,
4 by 180 degrees in the vertical direction, and house the claws 32 and 42 in the grooves formed around the recess 51 of the sole.
If the anti-slip fittings 3 and 4 are held in the closed position when used, it may damage the road surface, and the anti-slip fittings 3 and 4 may damage the road surface.
4 does not impede walkability.

Furthermore, in the usage conditions shown in Figures 3 to 6,
It is also possible to use one of the anti-slip fittings 3, 4 in a closed state and the other anti-slip fittings 3, 4 in an open state.

(Effects of the invention) The anti-slip fitting for shoe soles of this invention is configured and used as described above, so it can be used in eight stages depending on the condition of the frozen road surface, and has an anti-slip effect. can be strengthened.
