[0001] SPIKE UP AND DOWN DEVICE FOR SHOES [0002]

The present invention relates to a lifting device for a shoe spike, and more particularly, to a shoe spike lifting device for lifting a spike pin mounted on an outsole of a shoe so as to be movable up and down, And a lifting device.

In general, shoes are worn to protect the feet while walking or walking, and recently, shoes having various functions according to purposes have been developed.

For example, Korean Unexamined Patent Publication No. 2002-0068093 (published on Aug. 28, 2002) discloses a shoe for preventing slippage on a slippery road such as an ice sheet or a snowy road. A fixing support plate is inserted into a guide hole formed in the shoe sole, (See Japanese Patent Application Laid-Open No. 2000-28995) which allows the mobile upper plate having the means to be fitted back and forth in the longitudinal direction so as to be able to walk safely in a slippery place while protruding and protruding by movement of the movable upper plate have.

However, in Patent Document 1, since the area occupied by the fixed support plate and the movable top plate is too large, the shoe is not bent, so there is a problem in flexibility when walking, so that the fitting feeling is not good. Since the protruding portion is straightened by the spring, the protruding portion has a vertical straightness in the guide rod, and a gap formed by receiving the coil spring causes fluidity to the lateral direction inevitably. Therefore, when a load is applied from the upper portion in a state where the protruding portion is protruded, There is a problem that the guide bar can be easily broken while being inclined or bent at the guide bar.

As an example of the prior art for solving such a problem, Korean Patent Registration No. 10-1494885 (refer to Patent Document 2) discloses that a spike pin can be embedded between a shoe midsole and a sole, The foot slip prevention device according to any one of claims 1 to 3, wherein the foot slip prevention device includes a plurality of insertion holes formed in a bottom surface of the front half of the shoe sole, A casing portion of the casing formed integrally with the guide so as to protrude downward; A lifting portion having a plurality of spike fins for projecting and retracting through a center of the pin guide on a bottom surface of a lifting plate supported by a spring in a movable manner in the casing portion; A sliding portion for moving the lift plate to a predetermined height while sliding the slide plate having a bottom surface formed with a second guide protrusion formed to correspond to the first guide protrusion formed on the lift plate in a linear direction; A plurality of connecting members are connected to each other between the connection bands so as to extend integrally from the slide plates through the mutually spaced front and rear casing portions so as to extend in a mutually opposing direction with a predetermined width and a predetermined length, ; And a manipulation portion for allowing the slide plate to move forward and backward by a manipulation of a knob having one end of a shaft inserted into a holder formed on the heel side slide plate and protruding from the rear of the midsole, Device has been proposed.

However, Patent Document 2 has a problem that the manufacturing cost is high and the assemblability is bad because the structure is very complicated and the number of parts is large, and the productivity is lowered.

The second pin lifting unit 300 includes a second spring 350 that moves the second lifting member 320 upward by an elastic force.

For example, the second spring 350 may be a coil spring provided on the outer periphery of the second spike pin 321, and an upper end of the second spring 350 may be a coil spring, And the lower end of the second spring 350 is held in abutting contact with the bottom surface of the second lift space 341. The elastic force of the second spring 350 causes the second lift member 320 to be in contact with the bottom surface of the second lift space 341, .

The first spike pins 221 may be provided on the left and right sides, and the second spike pins 321 may be arranged in a row on the left and right in the front and rear, respectively. In accordance with the above- Can be freely changed.

The spike elevating apparatus according to the present invention is capable of moving the first slide member 210 and the second slide member 310 rearward as the one wire 131 is pulled when the adjustment knob 130 is rotated forward And the first spike pin 221 and the second spike pin 321 are lowered to protrude downward from the lower end of the outsole, thereby performing a slip prevention function.

When the adjustment knob 130 is reversely rotated, the first and second slide members 210 and 310 slide forward as the other wire 131 is pulled. At this time, the first spike pin 221 is slid, And the second spike pin 321 rise due to the elastic force of the first spring 240 and the second spring 350 and then enter the inside of the outsole.

Hereinafter, the operation of the spike pin will be described with reference to FIGS. 4 and 5, and the configuration of the present invention will be further detailed.

FIG. 4 is a partial cross-sectional view showing the operating state of the first pin lifting part 200 of the lifting device of the shoe spike according to the present invention, wherein FIG. 4 (a) shows a state in which the first spike pin 221 is lifted, b) shows a descending state.

4A, the first elevation member 220 is upwardly supported by the elastic force of the first spring 240, and the inclined surface 222 is supported by the first oblique protrusions (not shown) of the first slide member 210 212, respectively.

4 (b), when the first slide member 210 is slid rearward, the inclined surface 222 of the first elevation member 220 moves downward along the inclined surface of the first inclined projection 212, 1 spike pin 221 can be projected downward.

In contrast, when the first slide member 210 slides forward, the lifting member 220 can be moved upward by the elastic force of the first spring 240.

5 is a partial plan view and a cross-sectional view showing the operating state of the second pin lifting unit 300 of the lifting device of the shoe spike according to the present invention, wherein FIG. 5 (a) (B) shows a descending state.

5 (a), the second ramp member 320 is normally supported by the elastic force of the second spring 350 so that the second sloping projection 333 of the rotating member 330 is supported by the second And is inserted into the second guide hole 322 of the elevating member 320. [

5 (b), when the second slide member 310 is slid rearward, since the groove 311 and the protrusion 332 are engaged with each other, the rotational member 330 moves the second spike pin 321 toward the center (Counterclockwise in the drawing), and at the same time, the first inclined projection 333 rotates together.

At this time, while the first inclined projection 333 moves (rotates around the second spike pin) in the second guide hole 322 whose length direction is perforated in the arc, The upward movement of the rotary member 330 is prevented because the upper center of the rotary member 330 is inserted into the second axial hole 112 of the base plate 110 The second lifting member 320 moves downward and the second spike pin 321 can be projected downward.

When the second slide member 310 slides forward, the rotary member 330 returns to its original position. At this time, the second slant projection 333 abuts the inclined surface 323 of the second guide hole 322 The lifting member 220 can be moved upward by the elastic force of the second spring 240. As a result,

The above description has been made only for the embodiments described in the drawings, but the invention is not limited to the embodiments of the drawings. The first pin lifting part 200 disposed at the rear of the base plate 110 is disposed in front of the base plate 110 so that the first pin lifting part 200 structure is applied to both the front and rear sides The second pin lifting unit 300 can be applied to both the front and rear sides of the base plate 110 by the rotation of the rotating member 330. For this purpose, a second slide member 310 for rotating the rotating member 330 may be directly connected to the wire 131.
