Description

Shoes with antiskid

The present invention relates to shoes, including various sneakers, hiking boots and golf shoes or shoes, and more particularly, to a shoe having a non-slip device that allows the user to selectively exert a large friction force in accordance with the use conditions.

Korean Patent Publication No. 91-8963 discloses an anti-slip device installed on a shoe. The anti-skid device is fixed to the sole of the shoe support jaw, the assembly groove and the support portion formed with the jangbu and stepped with an adhesive, the support portion is rotatable and a non-slip rotating plate formed with a plurality of conical protrusions on one side at regular intervals Can be rotatably coupled, but inserts the support hole into one coupling hole of the non-slip rotating plate and the coupling hole of the support, and combines it with the “E” ring. The other side of the anti-slip rotating plate can form a protrusion and a locking portion to be detachable from the locking groove of the support. It was to be combined so as to lock.

Such a conventional anti-slip device detaches and rotates an anti-slip swivel plate installed in the sole bottom of a shoe depending on whether it is walking indoors in winter or on snow or ice accumulated on the ground of the outdoor, thus preventing accidents caused by slipping when walking. Although it could be prevented, it was very inconvenient to operate the anti-slip swivel plate so that the projections on the non-slip swivel plate face the inside or outside of the shoe sole. That is, since the means for fixing the non-slip rotating plate to the selected sole or not in use state is located on the sole of the sole of the shoe, when it is used for a long time, the normal function of the fixing means can be expected by the wear or damage of the fixing means. There was no problem, it was difficult to handle the fixing means when foreign matters stuck or pinched around the heavy means while walking, and there is a problem that it is very inconvenient to operate the anti-skid rotating plate while wearing shoes.

The present inventors have diligently studied to solve the above-mentioned problems of the prior art, so that the non-slip means that provide a great frictional force to the shoe can be released from the sole of the shoe toward the inside or the outer of the shoe sole, and this haunting operation The present invention has been found to be able to easily perform the selective operation of the anti-slip means even if the shoe is worn, if it can be operated from the side of the shoe sole, and improve the durability and reliability even under severe use conditions. It was completed.

It is therefore an object of the present invention to provide a shoe having an anti-slip device, wherein the friction protrusion can be projected from the inside of the shoe sole to the outside, and such a lifting operation can be performed on the side of the shoe sole.

※ Explanation of main parts of drawing

10: outsole, 12: bottom, 14: indentation, 16: friction protrusion

18: non-slip plate, 22: carbon element, 24: shaft, 26: eccentric cam

28: side, 30: adjustment knob, 32: elastic member

In the present invention, as illustrated in FIG. 1, a recess 14 is formed at the bottom 12 of the sole 10, and a non-slip plate 18 having a plurality of friction protrusions 16 formed on a surface thereof is provided at the recess 12. (14) It was made to be installed in the appearance.

The non-slip plate 18 is fixed to the wall 20 of the concave portion 14 so that the other end of the holding member 22, such as a tension coil spring, whose one end is fixed, is fixed to the wall 20. It is supported in a hanging form. The shaft 24 penetrates through the center of the recessed part 14 of the sole 10. An eccentric cam 26 is fixed to the center of the shaft 24, an adjustment knob 30 is fixed to one end of the shaft 24 extending toward the side 28 of the sole 10, and the shaft 24 The other end of) is supported by the sole 10 so as to be rotatable.

One end of the elastic member 32, such as a leaf spring, is fixed to the blocked wall 20 of the concave portion 14 with a screw 34, and the free end of the elastic member 32 is the eccentric cam 26. ) In contact with A plurality of grooves 36 are formed at the edge of the non-slip plate 18, and a plurality of guide protrusions corresponding to the grooves 36 are formed on the inner circumferential surface 38 of the recess 14 in the sole 10. 40 is formed so that the non-slip plate 18 can move accurately in the vertical direction along the guide projection 40 in the recessed portion 14 of the sole 10.

In the present invention, the adjustment knob 30 does not protrude into the concave portion 42 formed on the side portion 28 of the sole 10 in order to prevent damage to the obstacle during walking without damaging the walking. Positioning is desirable. When the present invention configured as described above is well represented in FIG. 2 and the shoes are used indoors or in places where large frictional force is not required, the uniaxial direction of the eccentric cam 26 is in contact with the anti-slip plate 18. The non-slip plate 18 is formed by the tension of the anti-skid plate 18 and the finger member 22 fixed to the wall 20 of the recessed portion 14 in the sole 10, respectively. 14) to be used in the state where the friction protrusion 16 does not protrude out of the sole 10.

And as is well represented in Figure 3, when the shoes are used in the outdoors or ice or rough terrain requires a large friction force by rotating the shaft 24 with the adjustment knob 30, the long axis direction of the eccentric cam 26 is slippery When the contact plate 18 is in contact with the anti-skid plate 18 is lowered in the concave portion 14 of the sole 10 while extending the stop member 22. Therefore, the friction protrusion 16 of the anti-skid plate 18 protrudes out of the sole 10 to obtain a large friction force necessary for preventing slip of the shoe.

In the present invention, the anti-skid plate 18 and the friction protrusion 16 is preferably made of stainless steel, ABS resin or engineering plastic in consideration of wear resistance, corrosion resistance and durability life.

The present invention allows the non-slip plate 18 having the friction protrusions 16 to be protruded out of the sole 10 in the recessed portion 14 of the shoe sole 10, and the anti-slip plate 18 Since the operation can be performed on the side portion 28 of the sole 10, the position of the anti-skid plate 18 can be easily changed even when the shoe is worn, and the shoe slips even under prolonged use or harsh use conditions. It can keep the prevention effect, so it has the advantages of excellent durability and operation reliability.
