The elastic force is installed to act.

Meanwhile, the snow chain has a cover member 400 having a substantially disc shape as shown in FIG. 2 and having a plurality of elastic fixing pieces 410 formed at regular intervals on an outer circumferential surface thereof, and the chain body 200. The elastic fixing piece 410 of the cover member is inserted and fixed on the outer circumferential surface of the chain support plate 120 so that the surface of the chain support plate 120 coupled to the wheel bolt 10 is sealed without being exposed to the outside. The fixing groove 126 is formed, the drive ring 256 and the chain fixing plate 310 coupled to the outer case 220 in the state that the chain body 200 is coupled to the chain support plate 120 is external The fixing groove 229 is formed on the outer case 220 so that the elastic fixing piece 410 of the cover member 400 is inserted into and fixed to the outer case 220.

The operation of the present invention as described above with reference to Figures 1 to 7 as follows.

Snow chain according to the present invention when the snow road or ice road driving frequently during the winter, as shown in Figure 5, using the auxiliary fastening member 110, the chain support plate 120 is mounted on the tire side wheel bolt 10 When the snow chain is required to be mounted while driving, the chain body 200 may be removed and mounted.

At this time, the chain support plate 120 is fastened to the surface, such as the fastening hole 125 and the auxiliary fastening member 110 is fastened because the appearance is poor, so that the cover member 400 is coupled to the chain support plate and sealed as described above. Problems caused by poor appearance can be solved. And the process of coupling the cover member 400 to the change fingerboard 120 is to force the pressing force inward in the state in which the elastic fixing piece 410 of the cover member is matched with the fixing groove 126 of the chain support plate 120 When the elastic fixing piece 410 is elastically coupled to the fixing groove 126.

When only the chain support plate 120 and the cover member 400 as described above are driven while the snow road or the ice road is actually driven, the cover member 400 from the chain support plate 120 is first shown in FIG. 6. The chain body by using the chain coupling means 300 in a state where the chain body 200 having the size of the non-slip member 240 adjusted to match the tire size of the vehicle owned by the vehicle is located on the tire side When the 200 is fixed to the tire side, and then the cover member 400 is fastened to the outer case 220 side, the mounting of the snow chain is completed as shown in FIG. 7.

On the other hand, when the size of the tire is changed to the size of the non-slip member 240 is set to a specific size or when a different size snow chain is required by replacing the vehicle cover member as shown in Figs. When both adjusting pins 258a of the driving ring 256 are pulled while the 400 is removed, the spring 258b is inserted into a specific pin insertion hole 259 (for example, a pin insertion hole at the “a” position) by the elastic force of the spring 258b. Since the lower end of the adjusting pin 258a is separated from the pin insertion hole a, the driving ring 256 is free to rotate, and when the external force is applied to the adjusting pin 258a in the clockwise direction, the driving is performed. The ring 256 is interlocked and rotated clockwise.

When the driving ring 256 is rotated in the clockwise direction, the connecting bracket 254 coupled to the engaging hole 256a formed on the outer circumferential surface of the driving ring rotates in the clockwise direction, and thus the link coupled through the pin 251. While the lower end of the 252 is rotated in a counterclockwise direction, the sliding member 230 coupled to the other end of the link 252 is moved forward and thus the non-slip member 240 coupled to the sliding member 230 is interlocked. To move forward.

That is, when the driving ring 256 is rotated clockwise by the adjustment pin 258a, the inner diameter dimension (inner diameter corresponding to "x" in FIG. 3B) between the non-slip member 240 and the non-slip member 240 is increased. Therefore, a snow chain that can be used for a tire of a larger size is formed. In this way, the adjusting pin 258a is rotated so that the inner diameter size of the non-slip member 240 suitable for a particular tire is set. When releasing the pressing force acting on the spring, the adjustment pin 258a is moved downward by the elastic force of the spring 258b and its lower end is inserted into and fixed in the corresponding pin insertion hole (for example, the pin insertion hole in the "c" position). The ring 256 is fixed on the seating portion 224 of the outer case 220 in a state in which rotation is impossible.

On the contrary, when the size of the tire on which the snow chain is mounted becomes smaller, when the driving ring 256 is rotated counterclockwise by pushing the adjustment pin 258a counterclockwise to reverse the operation of the above-described operation, the linkage is interlocked. Since the non-slip member 240 is reversed by the reverse operation of the connecting bracket 254, the link 252, and the sliding member 230, the inner diameter dimension (x) of the non-slip member 240 in contact with the tire is reduced. do.

Since the non-slip member 240 is coupled to the direction control member 238 rotatably coupled to the sliding member 230, it is easy to change the angle in the process of mounting the anti-slip member 240 on the tire. Since the fixed piece insertion hole 238a of the direction adjusting member 238 is eccentrically formed, the front and rear protrusion lengths of the non-slip member 240 can be adjusted using this direction adjusting member so that the inner diameter is adjusted. (x) can be adjusted, for example, as shown in Figure 4d the direction of the direction adjusting member 238 is located in the direction of the distance (g) with a greater distance to the outer periphery from the fixed piece insertion hole 238a to the outside When the fixing piece 244 of the non-slip member 240 is inserted in the above state, the distance between the fixing piece insertion hole 238a and the outer circumference is shorter than the length of the short side f. Become shorter than smaller It is possible to mount a tire of IZ and, on the contrary, rotate the direction adjustment member 238 by 180 ° and slide it in a state where the side f having a smaller distance from the fixed piece insertion hole 238a to the outer periphery is located outward. When the fixing piece 244 of the preventing member 240 is inserted, the protruding distance of the non-slip member 240 is increased by the length difference between the fixing piece inserting hole 238a and the larger side (g). Larger tire sizes can be installed.

Meanwhile, as described above, when the length of the non-slip member 240 is adjusted to fit the tire to which the snow chain is to be mounted, the locking jaw of the chain fixing plate 310 is positioned in the state where the chain body 200 is mounted on the tire. When the 312a is positioned in the space between the locking jaws 122 of the chain support plate 120 and then pulls the fixing plate adjusting member 320 outward, the locking jaws 122 and the locking jaws 122 of the chain support plate 120 are pulled out. When the operating portion 324 of the fixed plate adjustment member positioned between the () is moved inward and at the same time the chain fixing plate 310 is pushed and turned, the chain fixing plate 310 side locking jaw (312a) is the chain support plate 120 When the external force applied to the fixed plate adjusting member 320 in this state is caught by the locking step 122 of the side, the fixed plate adjusting member 320 is moved inward by the elastic force of the spring 326 so that Actuator 324 is chain support plate 120 The chain body 200 is firmly mounted on the chain support plate 120 because it is inserted into the space between the locking step 122 and the locking step 122 to restrict the rotation of the chain fixing plate 310.

When the chain body 200 is coupled to the chain support plate 120, the elastic fixing piece 410 of the cover member 400 coincides with the fixing groove 229 of the outer case 220 as shown in FIG. 7. When the pressing force is applied inwardly in a state where it is positioned, the cover member 400 is mounted on the outer case 220 while the elastic fixing piece 410 is elastically coupled to the fixing groove 229.

According to the snow chain according to the present invention as described above, since the chains or wires are connected to each other and are not integrally attached to the outer surface of the tire, they are integrally mounted on the side surface of the tire, thereby preventing the problem of being stretched or peeled off and also with the ground. The noise is not generated at the time of contact, as well as the riding comfort is improved, the assembly is very easy and the assembly time is shortened, there is an effect that the problem such as damage to the skin during the assembly process is prevented.

In addition, since the inner diameter of the non-slip member seated on the running surface of the tire can be changed in various ways, it is possible to mount it on tights of various sizes, so that the snow chain can be re-mounted even when the tire size is changed or the vehicle is replaced. The problem to be purchased is solved, the consumer burden is reduced and there is an effect that can prevent the waste of resources.

In addition, when the chain body is not mounted while the chain support plate is fixed to the wheel bolts, the chain support plate may be sealed by mounting a cover member, and even when the chain body is mounted, the chain member may be sealed by mounting the cover member. It is a very useful design that can improve the aesthetics by blocking exposure to the outside of the poor appearance and thereby achieve consumer satisfaction.
