The second clasps 162 corresponding to the first clasps 120 are respectively attached to the extension portions of the extension rods 160 extending in this way, and the first clasps 122 correspond to both ends of the second clasps 162. The second locking protrusions 164 are attached to each other. Preferably, the second latch 162 forms the same curvature of the second locking ring 136, and the second locking protrusion 164 is formed integrally with each other while crossing each other on one side of the second latch 162. do. At this time, the other end of the wire is fitted to the second locking projection 164, the wire 170 is selectively tightened by the operating unit 156 pivoting around the hinge 155 of the body 154, Loose

Hereinafter, the state of use of the snow chain 100 for a two-wheeled vehicle formed as described above will be briefly described.

3A and 3B are views illustrating a state in which the snow chain for the motorcycle shown in FIG. 1 is mounted on a tire.

3A and 3B, the snow chain 100 for a two-wheeled vehicle according to the present invention is first disposed to closely contact the support 110 on one side of the tire wheel W. Under such a condition, one locking hole 132 of the locking part 130 is brought into close contact with the other side of the tire wheel (W). At this time, the first portion of the support 110 in a state in which the operating portion 156 of the clamp 152 is opened to the first locking ring 134 side so that the second latch 162 may be advanced toward the first locking ring 134 side. The clasp 120 and the second clasp 162 of the lock 132 are in close contact with each other. At this time, the second bar 146 of the spacer 142 extends toward the support 110, and adjusts the third bar 148 fastened to the second bar 146 to both ends of the fourth bar 150. The first support 112 and the second support 114 of the support 110 is adjusted to be in close contact with the outer surface.

As such, when the support 110 and the one lock 132 are in close contact with both sides of the tire wheel W, one end of the wire 170 is inserted into the first catching protrusion 122 formed on the first catch 120. The other end of the wire 170 is fitted to the second locking protrusion 164 formed on the second latch 162. Under such a condition, when the operating part 156 of the clamp 152 is rotated to the other side of the first locking ring 134, the fixing protrusion 158, the extension rod 160, and the extension rod 160 of the operating part 156 are rotated. The attached second latch 162 and the second latching protrusion 164 are transferred to the other side of the first locking ring 134 along the operation part 156 so that the first locking protrusion 120 and the second locking protrusion 164 are attached. The wire 170 inserted in the) is tightly attached to the outer surface of the tire.

As described above, a plurality of locks 132 are coupled to the support 110 by using the same method to one side of one lock 132 coupled to the support 110 to continuously combine to form a single ring shape. Let's do it.

As described above, the snow chain 100 for a two-wheeled vehicle according to the present invention includes a support 110 and a plurality of locks 132 disposed on one side and the other side of the tire wheel W, and the support 110 The second locking protrusion 164 includes a first locking protrusion 122 into which one end of the wire 170 is fitted, and the other end of the wire 170 is fitted into the locking hole 132, and the second locking protrusion 164 is transferred by the clamp 152. By using the clamp 152, the wire 170, which is fitted to the first locking protrusion 122 and the second locking protrusion 164, can be brought into close contact with the tire in a short time according to the operation of the clamp 152. The braking force and stability can be secured in the system, so there is an advantage to drive safely.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims You will understand.
