Description

[0001] Apparatus for sliding prevention of shoes [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device for a footwear, and more particularly, to a slip prevention device for a foot, which is inserted into a sole of a shoe so that a slip phenomenon can be prevented .

Usually, the sole of the shoe is formed so as to form a concave-convex bottom surface for preventing slippage. However, since the sole is required to have a predetermined rigidity and a buffering action, it is mostly made of a rubber material.

For this reason, slipping phenomenon frequently occurs on walking because it can not prevent the slipping phenomenon when walking on the road such as snowy road, icy road, and mountain road.

Particularly, in the case of fishing in shoe, it is easy for the fishing wearer to unintentionally leave the initial position due to the movement of the fish due to the nature of the fish, and the surface of the seabed is also slippery, A means for preventing slippage was required.

For example, in the 'non-slip device for shoe (publication No. 10-2002-0068093)', a movable upper plate having a pushing means is inserted into a fixed support plate inserted in a guide hole formed in the shoe sole so as to be movable back and forth in the longitudinal direction , And a technique has been proposed in which the protruding portion is moved by the movement of the mobile top plate so that it can be safely walked in a slippery place.

That is, the fixed support plate and the movable upper plate are formed on the bottom of the shoe so as to be formed in the middle, and the protrusions are respectively supported by the spring in the shoe sole.

However, since the fixed support plate and the movable top plate occupy a large area in the shoe, the shoe can not be bent, resulting in poor flexibility in walking.

In addition, since the protrusions are independently provided in the shoe sole and are tacked on the guide rods by the coil springs, fluidity in the lateral direction is unavoidably inevitably caused by the gap generated while accommodating the coil spring with the straightness of vertical movement in the guide rods, When the load is applied from the upper portion, the protruding portion tilts or warps on the guide rod and is easily broken.

Therefore, there is a desperate need for research and development of means for preventing the slip of the shoe sole in a new way.

Fig. 6 is a first exploded view of Fig. 5, and Fig. 7 is a second exploded view of Fig. 6 and 7, it can be seen that the anti-skid device 100 comprises the body 110, the lid 120, the elastic member 130, the spike pin 140 and the receiving hole 150 The details of each configuration will be described below.

The body 110 of the present invention is inserted into the insertion hole 21 formed in the sole 20 and has a receiving hole 150 formed in its longitudinal direction.

Before describing the body 110, a structure of the insertion hole 21 formed through the shoe sole 20 such as a fishing line will be described. The through-hole 21 may include a first fitting space 21a, a second fitting space 21b, and a through-hole 21c.

The first fitting space 21a is formed at the upper end of the sole 20 and has a size corresponding to the diameter of the first body member 111 so that the first body member 111 can be inserted and seated. .

An entrance space 21a 'having a diameter smaller than that of the first fitting space 21a may be formed at the upper portion of the first fitting space 21a so as to communicate with the outside of the sole 20. The entrance and exit space 21a' Is formed to be smaller than the diameter of the first fitting space 21a so that the first body member 111 can be stably fitted into the first fitting space 21a. (See Fig. 3)

Second, the second fitting space 21b is formed to have a smaller diameter than the first fitting space 21a, and the second body member 112 is accommodated.

Since the second fitting space 21b has a smaller diameter than the first fitting space 21a at this time, the first body member 111 is inserted into the first fitting space 21a and the second fitting space 21b, So that it can be stably supported at the boundary portion.

Third, the penetrating space 21c is formed to have a smaller diameter than the second fitting space 21b, and it provides a space in which the spike pin 140 can be moved up and down by the elastic member 130 having an elastic force .

That is, the penetrating space 21c allows the spike pin 140 to move to the inside and outside of the sole 20. The diameter of the penetrating space 21c is formed to be smaller than the diameter of the second fitting space 21b The second body member 112 can be stably supported at the boundary portion between the second fitting space 21b and the through space 21c.

For reference, it is preferable that a cushion member 22 capable of providing a stable wearing feeling is mounted on the upper portion of the sole 20. [ As the cushion member 22 is attached to the upper portion of the sole 20 in this way, it is possible to block the departure of the shoe anti-slip device 100 from the sole 20.

Subsequently, the body 110 is composed of a first body member 111 and a second body member 112 and functions to be seated in the first fitting space 21a and the second fitting space 21b of the sole 20 .

First, the first body member 111 is configured to provide a space in which the lid 120 can be seated.

The first body member 111 is seated in the first fitting space 21a formed at the upper end of the sole 20 so as to be parallel to the upper surface of the sole 20 as described above.

The second body member 112 is formed such that the diameter of the second body member 112 is smaller than that of the first body member 111 at the lower portion of the first body member 111. The elastic member 130 and the spike pins 140 A space is provided in which the spike pin 140 can be moved up and down by the elastic force of the elastic member 130.

The lower end of the second body member 112 is formed with an inner end 112b which is bent along the circumferential direction. The upper end of the inner end 112b is provided at the lower end of the step 141 protruding from the upper end of the spike fin 140 Thereby preventing the spike pin 140 from being detached from the second body member 112 in the downward direction.

3, 5, and 6, a stopper 112a is protruded from the outer surface of the second body member 112, so that the stopper 112a can be fixed to the inner surface of the insertion hole 21 in an interference fit manner. Specifically, when the shoe anti-skid device 100 is inserted into the insertion through hole 21, the stopper 112a is inserted into the inner surface of the second fitting space 21b because the shoe sole 20 is made of a rubber material. The non-slip device 100 is prevented from unnecessarily rotating by securing the coupling force between the through-hole 21 and the non-slip device 100.

The elastic member 130 of the present invention is inserted into the receiving hole 150 and has a resilient force.

In other words, the elastic member 130 is inserted into the second receiving hole 152, and the elastic force of the shoe pin 140 due to the elastic force of the shoe wearer during walking or the elastic force of the shoe sole 20 It acts to drive the up and down movement.

In other words, when the elastic member 130 having elasticity is self-contracted when the wearer's load or the sole 20 meets a pointed portion such as a seaweed, the spike pin 140 is inserted into the sole 20, The spike pin 140 returns to a state where the spike pin 140 is projected to the outside of the sole 20 again as the state of the elastic member 130 is restored.

For reference, the elastic member 130 is preferably a spring, but any elastic member may be used.

The cover 120 of the present invention is seated inside the upper end of the body 110 and covers the accommodation hole 150 to prevent the elastic member 130 from coming off.

That is, the lid 120 is seated in the first receiving hole 151 formed in the first body member 111 and the elastic member 130 and the spike pin 140 inserted in the second receiving hole 152 So as to prevent a phenomenon of coming out from the upper side of the sole 20.

The lid 120 includes a center lid plate 121 and a wing plate 122 protruding from both sides of the center lid plate 121. The second body member 112 has a second longitudinally extending through- By closing the accommodation hole 152, the elastic member 130 and the spike pin 140 are prevented from deviating.

The center lid plate 121 is seated in the first receiving hole 151a formed in the first body member 111 and the first receiving hole 151a in the case of the wing plate 122 And is seated in the first receiving hole 151b formed to be communicated with the first receiving hole 151b.

The spike pin 140 of the present invention is formed at the lower end of the elastic member 130 and is vertically moved in a state of being inserted into the accommodation hole 150. The spike pin 140 protrudes to the lower portion of the sole 20, And the elastic member 130 is pushed into the inside of the sole 20 by a load.

Particularly, conventionally, the pin is normally inserted into the sole 20 and then protruded to the bottom of the soles by the load of the wearer. However, in such a case, there are many inconveniences in walking due to the protrusion due to the pressure of the load.

That is, conventionally, if the load of the wearer does not act largely in the gravitational direction, it means that the pin can not protrude to the bottom of the soles and thus the slip prevention can not be efficiently achieved. Accordingly, in the present invention, the spike pin 140 is normally protruded to the lower portion of the sole 20, and when the walking load is applied to the wearer, or when the sole 20 is grounded at the pointed portion, The slip prevention can be efficiently achieved even if the wearer does not apply a large force to the foot.

3 shows a state in which the spike pin 140 is positioned when the load of the wearer is not normally applied. In the state where the spike pin 140 protrudes to the lower portion of the sole 20 The spike pin 140 protruding to the lower portion of the sole 20 originally prevents slipping on the surface of the seabed or the like where the surface of the seawater is not uniform due to the presence of the spike pin 140 There is an effect that can be.

Conversely, referring to FIG. 3B, it can be seen that the spike pin 140 is inserted into the inside of the sole 20 when the load of the wearer during walking or the bottom of the sole 20 is grounded. 3B, when the load of the wearer or the bottom surface of the sole 20 is grounded or the like, the maximum contractile force of the elastic member 130 lowers the lower end of the spike pin 140 to the lower end of the sole 20 .

In addition, it is preferable that the spike pin 140 is made of a rigid metal material that can minimize damage even if it comes into contact with the ground.

The accommodation hole 150 of the present invention has a space for accommodating the spike pin 140, the elastic member 130, and the cover 120 as it goes from the lower part to the upper part.

The receiving hole 150 includes the first receiving hole 151 formed in the first body member 111 and the second receiving hole 152 formed in the second body member 112, So that it is possible to flex the up and down movement of the main body 140.

The first receiving hole 151 is formed at the center of the first body member 111 and is formed in the first body member 111 such that the center lid plate 121 is seated, And a first receiving hole 151b formed in the first receiving hole 151a so as to communicate with the first receiving hole 151a.

Second, the second receiving hole 152 is formed in the second body member 112 so as to communicate with the lower portion of the first receiving hole 151a. The second receiving hole 152 has a diameter that is relatively larger than the first receiving hole 151a So that the elastic member 130 and the spike pin 140 can be accommodated.

In the case of the elastic member 130 and the spike pin 140 accommodated in the second accommodating hole 152, the elastic force of the elastic member 130 allows the spike pin 140 to freely move the through space 21c of the sole 20 It can be moved up and down.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied otherwise without departing from the spirit and scope of the invention.

Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to illustrate them, and the scope of the technical idea of the present invention is not limited by these embodiments.
