{SNOW CHAIN FOR TIRE OF VEHICLE}

The present invention relates to a tire snow chain, and more particularly, to a tire snow chain which has a slip prevention function for preventing a vehicle from slipping on an eye track, and is easy to install and remove when mounted on a tire, The present invention relates to a tire snow chain which is easy to store and carry.

In general, the snow chain is installed on a tire to prevent slipping of the vehicle when the vehicle is running on a road with a long snowfall or freezing, so that friction between the tire and the road surface is increased to ensure safe operation Device.

As a conventional technique relating to snow chains, there is a technique such as that disclosed in Japanese Patent Application Laid-Open No. 10-2007-0019535.

Such conventional techniques include an inner chain which can be closed by a circle or a ring on the side of the wheel facing the inside of the vehicle, an outer chain which can be closed by a circle or a ring on the side of the wheel facing the outside of the vehicle, And an anti-slip chain arranged in various ways on the tire tread of the wheel by connecting the chain and the outer chain.

In order to mount the snow chain on the wheel, the outer chain and the inner chain are extended to both sides with the wheel at the center at the bottom of the wheel, and the outer chain and the inner chain are wrapped around the front and rear sides of the wheel, The upper and lower ends of the inner and outer chains are fastened together.

Then, the anti-slip chains are variously arranged on the tread of the tire of the wheel, thereby increasing the frictional force between the tire and the road surface.

However, according to the snow chain according to the related art, it is very inconvenient and difficult to install on the tire due to its structure, so that it takes much time when there is no passenger or the driver is female, There was a problem that storage was difficult.

Further, since snow chains of different sizes are required depending on the size of the tires, there is a problem that a snow chain must be additionally provided depending on the type of the vehicle.

Therefore, it has a slip prevention function for preventing the vehicle from slipping on the snowy road. It is easy to install and remove when mounted on a tire, and can be applied to any kind of tire, A realistic and applicable technology that can be provided is desperately needed.

Here, the first stopper 311 has an elastic force at the lower side of the inner surface of the first fastener 310 and may extend upward.

In addition, the second fastener 320 is inserted in the lower vertical direction at the end of the fastening part 200 that has passed through the first fastener 310, and is fastened to the fastening part 200 And a second stopper 321 to move the second stopper 321 only in the downward direction.

At this time, the second stopper 321 has an elastic force at the upper side of the inner side surface of the second fastener 320 and can be extended downward. In order to increase the fastening force, the second stopper 321 is formed at the upper side with a second fastener 320 may be inclined in the direction of the bending part 400.

In addition, in the embodiment of the present invention, the first fastener 310 and the second fastener 320 constituting the fastening part 300 are formed as a cut-out part having a 'T' So that they can be injection-molded into a single mold.

Here, in the embodiment of the present invention, as shown in the figure, a portion where the latching portion of the second fastening member 320 is inserted may be formed narrower than a portion of the latching portion of the first fastening member 310 have.

In the meantime, as shown in the drawing, the hooking part 500 can hang hook means such as rubber band for preventing flow during cornering, and has a ring shape and is formed at one end of the fastening part 300 .

That is, by fixing the leopard, the string, the chain, etc. having elasticity to the hooking part 500, the adjacent snow chains are connected and supported to each other so that the vehicle with the snow chain is driven suddenly or repeatedly to the left or right It is possible to prevent the lateral flow which may occur in the case of the above.

As described above, according to the present invention, the stopper can be prevented from being separated from the stopper due to the left-right flow without being released by the external collision by making the structure for moving the stopper only in one direction within the plurality of fasteners.

In addition, the inner space of the secondary fastener constituting the fastening portion to which the fastening portion is doubly fastened is formed to have a narrower space width than that of the primary fastening portion so that the fastening portion is fitted with interference fit, The part is not projected to the outside, so that it is not necessary to separately perform the cutting operation, and the finish can be finely and finely apparent.

In addition, the present invention can reduce the number of molds in the manufacturing process by forming the snow chain in a unitary structure in which a plurality of fasteners constituting the fastening portion are formed so as to face each other, so that the manufacturing process and the manufacturing cost are reduced have.

FIG. 5 is an enlarged cross-sectional view of the fastening portion shown in FIG. 4 fastened with the fastening portion, and FIG. 6 is a plan view of the fastening end portion of the tire snow chain shown in FIG.

As shown in the drawing, a tire snow chain according to an embodiment of the present invention includes a first fastening hole 310 forming a fastening part 300 after forming a circular space part which surrounds and surrounds the tire circumference, When the latching part 200 is inserted in the upper vertical direction, the first stopper 311 moves in the upward direction corresponding to the latching pattern formed in the latching part 200 in the first fastening hole 310 Respectively.

Next, in order to perform an operation in which the circular space portion can be reduced but not expanded when the end of the engagement portion 200 is pulled, the second fastener 320 constituting the fastening portion 300 is fastened When the end of the latching part 200 that has passed through the first fastening hole 310 is inserted in the lower vertical direction, the latching part 200 is fastened by the second stopper 321 to the latching part 200 inside the second fastening hole 320 And moves only in the downward direction corresponding to the pattern.

At this time, since the latching part 200 is formed with the latching blade 210 which is hooked on the cut-out part of the second fastening tool 320 on the side of the end part thereof, the latching blade 210 is prevented from being caught in the internal space of the second fastening tool. It can be stopped at a suitable depth as it becomes a structure to be fitted with a fitting.

Further, as shown in the drawing, a groove portion that facilitates gripping may be formed on one side of the engagement wing 210.

In the embodiment of the present invention, as shown in the drawing, the first stopper 311 and the second stopper 321 are provided with pushing portions 301 and 302 protruding upward from the upper side, respectively, It is possible to release the fastening of the fastener 200.

As described above, the tire snow chain according to the embodiment of the present invention includes the unlocking depressions extended outward from the unidirectional stoppers provided in the plurality of fasteners constituting the fastening portion, Even after the coupling is completed during installation, it can be adjusted as needed and reusable after use.

Further, according to the present invention, it is possible to form a circular space portion that surrounds and surrounds the tire, and when the end of the engagement portion is pulled, the circular space portion can be reduced but not expanded, .
