It is preferable to be able to be fastened to any one of the groove (103a).

In addition, the operating member 106 has a rotating hole 104, as shown in the bracket 107a formed in the circumferential direction at the outer circumferential portion of the fixed disk 107 in close contact with the outer surface of the wheel, that is, the wheel or wheel cap By being respectively fixed by the fixing pin 104a, the pressing portion 105 of the operation member 106 has a form protruding to the outer surface of the tire.

Here, the guide shaft 108 protrudes a predetermined length from the center of the fixed disk 107 to the side, and the ratchet gear 108a is formed in the axial direction in a predetermined area of the outer surface of the guide shaft 108. The ratchet gear 108a has a sawtooth shape having a predetermined inclination angle in the axial direction at the fixed disk 107.

In addition, a second screw portion 108b is formed at the other end of the guide shaft 108, and the pressure pad 109 is inserted into the guide shaft 108 through the guide hole 109a as shown in FIG. The outer diameter surface of the pressing pad 109 is in close contact with the inner surfaces of the plurality of pressing portions 105 fixed to the stationary disk 107 by a tapered portion 109c inclined at a predetermined angle toward the insertion direction.

Here, the other end of the guide hole (109a) of the pressing pad 109 is formed with a receiving groove (109b) having an inner diameter relatively larger than the guide hole (109a) and is seated in the receiving groove (109b) first elastic member ( 110 is inserted into the guide shaft 108, the fixing bolt 111 to the second screw portion 108b so that the inserted first elastic member 110 can elastically support the pressure pad 109 toward the fixed disk 107 side. ), But it is preferable that the first elastic member 110 is smoothly supported by the washer 111a by inserting the washer 111a on the front surface of the fixing bolt 111.

In addition, a flange 115a is formed on the outer diameter surface of the tungsten hole 114, and a first stopper 115 having an inclined surface is inserted to allow the end portion to move toward the stationary disk 107 along the inclined surface of the tooth.

Then, the second elastic member 116 is inserted into the finger hole 114 to be inserted into the outer diameter surface of the first stopper 115 so as to support the flange 115a, and the second fixing screw 117 may be burnt. It is fastened to the paper hole 114.

On the other hand, the front end of the pressing portion 105 of the operating member 106 is formed with a fixing groove 119 opened to the outside as shown in Fig. 4, the circular third elastic member ( It is preferable to maintain the state that the inner surface of the pressing unit 105 is always in close contact with the outer diameter surface of the pressing pad 109 by the elastic force of the third elastic member 120 so that the 120 can be fitted.

In addition, the fourth elastic member 122 may be fixed to the ring portion 121 of the adjacent operation member 106 by forming a ring portion 121 on each side of the connection member 102 of the operating member 106. It is preferable to keep the connection member 102 mounted on the tire to maintain a constant distance from each other.

Therefore, when the anti-skid device according to the present invention is to be mounted, the spike unit 101 is coupled to cover the outer diameter surface of the tire as shown in FIG. 3A, and the spike unit 101 is shown in FIG. 3A. Likewise, it is relatively loosely coupled to the outer surface of the tire.

Here, the spike portion 101 is molded using a resilient material such as reinforced plastic or shape memory alloy, and even if the spike portion 101 is not completely coupled to the tire as shown in FIG. When 101 is pressed to one side by the connecting member 102, it is in close contact with the outer diameter surface of the tire as shown in Figure 3b.

Then, after all of the plurality of spikes 101 coupled to the fixed disk 107 is coupled to the outer diameter surface of the tire, pushing the pressure pad 109 to the tire side as shown in Figure 3b tapered portion of the pressure pad 109 109c is pushed toward the fixed disk 107 side to press the inner surface of the pressing portion 105 to the outside, at this time, the connecting member 102 of the operating member 106 is a fixed pin coupled to the bracket (107a) At the same time as the tire 104 is pressed toward the tire side with respect to the 104a and the turning hole 104, the spike portion 101 is in close contact with the outer diameter surface of the tire, and the anti-slip device of the present invention is mounted on the tire as shown in FIG.

Here, since the first stopper 115 is inserted into the second stopper 118 in the state of FIG. 3A in order to pressurize the fixed disc 107, the pressure pad 109 is rotated so that the first stopper 115 is rotated. The first stopper 115 is supported by the second elastic member 116 or the stationary disk while the first stopper 115 is pressed against the ratchet gear 108a. If the pressing force toward 107 is stronger than the second elastic member 116, the first stopper 115 moves toward the stationary disk 107 while causing the second elastic member 116 to be compressed.

In addition, the first stopper 115 moving toward the stationary disk 107 passes over the inclined surface of the toothed ratchet gear 108a and the plurality of ratchet gears 108a until the pressing force toward the stationary disk 107 is released. When the pressing force toward the stationary disk 107 is released, the first stopper 115 is engaged with the ratchet gear 108a by the elastic force of the second elastic member 116 and pressurized pad as shown in FIG. 4. Allow 109 to stop.

On the other hand, when the vehicle is driven after the anti-skid device according to the present invention is coupled to the tire as described above, in some cases the connection member 102 and the spike portion 101 may be moved in a state in close contact with the tire At this time, since the elastic restoring force of the plurality of fourth elastic members 122 connected to each other to the connection member 102 is equal, the connection member 102 is always maintained at a constant interval to prevent detachment of the spike portion 101. This prevents the spike portion 101 from being damaged.

In addition, since the circular third elastic member 120 is inserted into the fixing groove 119 formed at the tip of the pressing unit 105, the plurality of pressing units 105 are in close contact with the pressing pad 109 to always maintain a stable coupling state. To keep.

In addition, if the pressurizing part 105 and the connecting member 102 of the operating member 106 become loose while driving, the clearance between the ratchet gear 108a and the first stopper 115, which may be generated at all, may be fixed to the fixing bolt 111. The first stopper 115 is firmly engaged with the ratchet gear 108a because the first elastic member 110 that elastically supports the pressure pad 109 is supported by the pressure pad 109.

On the other hand, to remove the above-described anti-skid device from the tire, as shown in FIG. While the first stopper 115 compresses the second elastic member 116, the first stopper 115 may move toward the outer diameter surface of the guide shaft 108.

At this time, when the installer grips and pulls the pressure pad 109, the first stopper 115 is moved toward the fixing bolt 111 along the outer diameter surface of the guide shaft 108, and then the end of the ratchet gear 108a is guided. When the second stopper 118 connected to the outer surface of the shaft 108 in a groove shape is reached, the first stopper 115 may protrude to the second stopper 118 by the elastic force of the second elastic member 116. It will return to the initial state as 3a.

Therefore, since the spike portion 101 also has a loose coupling state to the tire as shown in FIG. 3A, the installer simply removes the spike portion 101 from the tire and stores it in a separately provided storage box to prevent slippage according to the present invention. You can simply uninstall it.

As described above, the present invention easily and simply mounts an anti-slip device mounted on a tire to prevent slippage of a vehicle driving on a frozen road in winter. This can be always maintained at equal intervals to prevent damage and detachment of the spike portion to achieve a safe running, and has the effect that the user can adjust the size in accordance with the size of the tire.
