The main body base 210 may be formed with a spike through hole 230 communicating the inner space S and the outside of the anti-slip unit 10.

The spike penetration hole 230 penetrates the main body base 210 vertically and corresponds to the diameter of the spike body 110 so that the spike 100 moves up and down along the inner peripheral surface of the spike through hole 230 can do.

The number of the spike penetration holes 230 may correspond to the number of the spikes 100.

A plurality of spike through holes 230 may be formed in the main body base 210 so as to correspond to positions where a plurality of spikes 100 are disposed.

Referring to FIG. 2, a plurality of spike through holes 230 may be provided at constant angular intervals. The spike penetration hole 230 has a plurality of spike through holes 230 on a concentric circle at a distance from the center of the main body 200 and has a plurality of spike through holes 230 concentrically located at a short distance from the center of the main body 200. A spike through hole 230 may be provided. The plurality of spike through holes 230 may be arranged concentrically around the rotational axis of the movable member 300.

The main body 200 has an elastic member receiving groove 240 formed on the inner side of the inner surface of the main body 200 defining the inner space S facing the concealment direction As shown in FIG.

That is, the elastic member receiving groove 240 may be formed along the periphery of the spike through hole 230 in a shape recessed on the upper surface of the main body base 210. A step may be provided between the elastic member receiving groove 240 and the spike through hole 230 by a difference in diameter between the elastic member receiving groove 240 and the spike through hole 230.

The elastic member receiving groove 240 may receive the elastic member 400. The elastic member 400 may be inserted into the elastic member receiving groove 240 to fix the position and provide the elastic force to the spike 100 so that the spike 100 moves in the concealment direction (upward direction). For example, the elastic member 400 may be composed of a spring.

The elastic members 400 may be disposed in the plurality of elastic member receiving grooves 240, respectively. The elastic member 400 may be a spring.

In the main body 200, an operation member through hole 250 through which the operation member 500 is passed may be formed in a vertical direction. That is, the operating member through hole 250 may be formed to penetrate the main body base 210 up and down, and to communicate the inner space S and the outside of the main body 200.

The operating member through-hole 250 may be formed to have a diameter corresponding to the diameter of the operating member body 510 so that the operating member body 510, which will be described later, is inserted and rotatable.

The main body 200 may have a threaded portion for engagement with the sole 1 on the side surface. On the outer circumferential surface of the main body 200 and the inner circumferential surface of the slip prevention unit receiving groove of the sole 1, a male screw portion is provided on one side of the female screw portion and can be screwed to each other.

For example, a screw thread 260 may be formed on a side surface of the main body 200, and a thread groove (not shown) may be formed on an inner peripheral surface of the slip prevention unit receiving groove of the sole 1.

Thereby, the anti-slip unit 10 is detachably engaged with the sole 1, so that the anti-slip unit 10 can be easily separated from the sole 1 if necessary.

A direction in which the spike 100 is exposed to the outside of the main body 200 is defined as a direction in which the spike 100 is concealed by the inner space S as a concealment direction Can be defined as an exposure direction (lower direction in the drawing).

The movable member 300 is moved in the first position to allow the spike 100 to move in the concealment direction or to move the spike that has already moved in the concealment direction in the exposure direction Do not allow.

The moving member 300 allows or forces the spike 100 to move in the exposing direction while moving from the first position to the second position.

The shifting member 300 does not allow the spike 100 already traveling in the exposure direction to move in the concealment direction to maintain the exposed state of the spike 100 in the second position.

The movable member 300 is positioned on the side of the concealment direction more than the spike 100 with respect to the second position and the contact member 300 does not contact the spike 100 during movement of the spike 100 even if the spike 100 moves in the concealment direction, And a contact area that comes into contact with the spike 100 already moved in the exposure direction.

The first position may be defined as a position at which the non-contact area is located on the spike 100, and the position where the spike 100 is allowed to move in the concealment direction through the non-contact area.

The second position is defined as the position at which the contact area is located on the spike 100 and the movement of the spike 100 already moved in the exposure direction in the concealment direction is not permitted due to contact with the contact area .

The movable member 300 can be in contact with the spike 100 while moving from the first position to the second position and when the spike 100 contacts the spike 100, .

The structure of the moving member 300 for performing the above functions will be described in detail below.

The movable member 300 is formed in a disc shape and is rotatably provided in the inner space S in the axial direction, so that the movable member 300 can rotate between the first position and the second position.

Here, the direction corresponding to the vertical direction may be defined to include a vertical direction, or a direction that is at a predetermined angle with respect to the vertical direction but roughly in a vertical direction.

4 through 6, the moving member 300 may include the spike receiving grooves 310 and 330 and the inclined portions 320 and 340.

The spike receiving grooves 310 and 330 may be formed in a groove shape which is recessed upward from the lower side of the moving member 300. The spike receiving grooves 310 and 330 may be formed to have a larger diameter than the outer diameter of the spike body 110 so that the spike 100 may be at least partially received within the spike receiving grooves 310 and 330.

At least a portion of the spike 100 may be concealed in the interior space S when the spike 100 is located in the spike receiving grooves 310, That is, when the movable member 300 is positioned so that the spike 100 is located in the spike receiving grooves 310, 330, the spike 100 can be allowed to move in the concealment direction.

A noncontact area that does not contact the spike 100 during movement of the spike 100 in at least a predetermined distance even if the spike 100 moves in the concealment direction can be defined as an area provided by the spike receiving grooves 310 and 330. [

The first position in which the spike 100 is allowed to move in the concealment direction (upward direction in the figure) through the non-contact area is that the spike receiving grooves 310 and 330 of the movable member 300 and the spike 100 are vertically The position of the movable member 300 that is positioned on the same line as the position of the movable member 300. [ Alternatively, the first position may be defined as the position of the moving member 300 such that the spike 100 is located in the inner region of the spike receiving groove 310, 330.

On the other hand, when the movable member 300 is located at the first position, the spike 100 can be forcibly moved in the concealment direction by the elastic member 400. [ The spike 100 can be moved in the concealment direction to a position where the movement of the spike 100 is restricted by the moving member 300 or the sole 1 and can be concealed inside the main body 200. [

The moving member 300 may be formed with inclined portions 320 and 340 by being recessed in a region adjacent to the spike receiving grooves 310 and 330 on one side of the moving direction of the moving member 300 facing downward in the drawing.

The slopes 320 and 340 may include first slopes 321 and 341 that are in contact with the spike while the moving member 300 moves from the first position to the second position.

The slopes 320 and 340 may include first seating surfaces 322 and 342 on which the spike 100 is seated while the movable member 300 is in the second position.

That is, the second position may be defined as the position of the moving member 300 where the spike 100 is positioned on the first seating surface 322, 342.

The slopes 320 and 340 are in contact with the spike 100 while the moving member 300 is moving from the second position to the third position and the slopes 320 and 340 move the spike 100 further in the exposure direction Two inclined surfaces 323 and 343, respectively.

The slopes 320 and 340 may include second seating surfaces 324 and 344 on which the spike 100 is seated while the movable member 300 is in the third position.

That is, the third position may be defined as the position of the moving member 300 where the spike 100 is positioned on the second seating surface 324, 344.

The contact area in which the spike 100 already moved in the exposure direction is not allowed to move in the concealment direction can be defined as an area provided by the slopes 320 and 340. [

When the movable member 300 is rotated in the first position toward the second position, the spike 100 comes into contact with the first inclined surfaces 321 and 341. The moving member 300 moves the spike 100 in the exposing direction (downward in the drawing) by the pressing due to the contact. At this time, the spike 100 moves on the first inclined surfaces 321 and 341 and moves in the exposure direction.

When the movable member 300 moves to the second position, the spike 100 is positioned on the first seating surface 322, 342. At this time, the spike 100 is not allowed to move in the concealment direction by the first seating surfaces 322 and 342.

When the movable member 300 is rotated from the second position toward the third position, the spike 100 comes into contact with the second inclined surfaces 323 and 343. The movable member 300 further moves the spike 100 in the exposure direction (downward direction in the figure) by the pressing due to the contact. At this time, the spike 100 moves along the second inclined surfaces 323 and 343, and further moves in the exposure direction.

When the movable member 300 moves to the third position, the spike 100 is positioned on the second seating surfaces 324 and 344 and the movement in the concealment direction by the second seating surfaces 324 and 344 It is not allowed.

That is, when the movable member 300 is in the first position, the spike 100 is allowed to be concealed in the internal space S, and the entire spike 100 is concealed inside the main body 200 It is not necessary and it is sufficient that the portion where the movable member 300 is concealed inside the main body 200 is larger than when the movable member 300 is located at the second position or the third position.

Further, when the movable member 300 is located in the second position, the spike 100 is maintained in the exposed state and moving in the concealment direction by the slopes 320, 340, more precisely, 322, < / RTI >

Further, when the movable member 300 is located at the third position, the spike 100 is maintained in the exposed state and moving in the concealment direction is performed by the inclined portions 320 and 340, more precisely, 324, 344). At this time, the length of the protrusion of the spike 100 to the outside of the main body 200 is longer than that when the shifting member 300 is located at the second position.

The spike grooves 310 and 330 are further recessed upward than the first seating surfaces 332 and 342 so that the spike 100 is allowed to be wholly or partially concealed in the internal space S of the main body .

Conversely, when the movable member 300 moves from the third position to the second position, the spike 100 is allowed to move in the concealment direction to a predetermined length. At this time, the spike 100 can be forced to move in the concealment direction by the elastic member 400. The predetermined length at which the spike 100 is allowed to move in the concealment direction may be a length corresponding to a height difference between the first seating surfaces 322 and 342 and the second seating surfaces 324 and 344. [

When the shifting member 300 is in the second position, the spike 100 is not allowed to move in the concealment direction by the first seating surfaces 322, 342.

The case where the movable member 300 moves from the second position to the first position can also be understood in the same manner.

On the other hand, although the seating surface is composed of two stages in this embodiment, a seating surface may be provided with a larger number of stages. The more the length of the protrusion of the spike 100 to the outside of the main body 200 can be finely adjusted, the more the number of the stages of the seating surface is provided.

In the present embodiment, the spike receiving grooves 310 and 330 are formed in the moving member 300 in the shape of a groove recessed from the lower side to the upper side of the moving member 300. However, It is also possible to form a spike hole completely passing through the upper and lower portions of the substrate 300. In this case, the spike 100 is formed by the contact of the spike head 120 with the inner side of the sole 1 facing the anti-slip unit in the state where the anti-slip unit is engaged with the sole 1 of the shoe, 100 can be restricted from moving in the concealment direction.

Since the moving member is provided as described above, the length of the protrusion of the spike to the outside of the main body can be adjusted stepwise. Even when the spike is located on the inclined plane, the length of the spike protruding outside the main body is changed, but it is difficult to stably support the spike so as not to move in the concealment direction. By forming the seating surfaces in multiple stages, the spikes can be stably supported in a state of protruding outside the main body with different lengths.

Fig. 7 is a view showing a part of the configuration of the anti-slip unit of Fig. 4, showing the moving member, the operating member and the fastening screw in the configuration of the anti-slip unit of Fig.

The operating member 500 may include an operating member body 510 and an operating member head 520.

The operation member body 510 can be rotated while being inserted into the operation member through hole 250 of the main body 200,

Referring to FIG. 7, a fastening screw thread portion 611 is provided on the outer circumferential surface of the fastening screw body 610, and an operation member head inner circumferential screw portion 523 is provided on the inner circumferential surface of the operation member head groove 522.

When the shifting member 300 and the operating member 500 are screwed together, the screwing of the shifting member 300 and the operating member 500, as the shifting member 300 is repeatedly rotated in one direction and the other, Can be separated. In order to prevent this, a fastening screw 600 is further provided. The fastening screw 600 is inserted and screwed into the operating member head groove 522 of the operating member head 520 through the fastening screw groove 360 of the moving member 300. At this time, the direction in which the fastening screw 600 and the operating member head 520 are screwed is opposite to the direction in which the operating member head 520 and the moving member 300 are screwed together, It is possible to effectively prevent the separation of the coupling part 300 from being detached.

The operation member body 510 can be formed by opening a wrench groove into which the wrench can be inserted in the exposure direction (the lower direction in the drawing). The wrench groove may be provided as a hexagonal groove 511.

The non-skid unit 10 configured as described above is configured such that the spike 100 protrudes out of the main body 200 by a force that the moving member 300 pushes and the moving member 300 pushes the spike 100 downward And can be hidden inside the main body 200 by the elastic member 400 when the force is removed.

The user rotates the operating member 500 in one direction to rotate the moving member 300 in one direction while the hexagonal wrench is inserted into the hexagonal groove 511 so that the spike 100 moves in the main body 200, It can be projected to the outside. The user rotates the operating member 500 in the opposite direction to rotate the moving member 300 in the opposite direction while the hexagonal wrench is inserted into the hexagonal groove 511 so that the spike 100 moves in the opposite direction to the main body 200, It can be concealed inside. Thus, the user can expose or hide the spike 100 through a simple operation, thereby improving the user's convenience.

The coupling between the operating member 500 and the shifting member 300 is doubly combined by the fastening screw 600 so that the coupling force between the operating member 500 and the shifting member 300 is strengthened. Therefore, it is possible to prevent the operation member 500 and the movable member 300 from being separated from each other even when the non-skid unit 10 is used by repeatedly rotating the movable member 300 in a direction opposite to the one direction, There is an advantage of having durability.
