Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-skid device for a vehicle which is mounted on a tire of an automobile or the like during snowfall and a joint lock body for the anti-skid device.

[0002]

2. Description of the Related Art As a conventional vehicle anti-skid device, there is, for example, one disclosed in Japanese Utility Model Publication No. 48-39282. This will be described with reference to FIG. 15. As shown in FIG. 15, the tire chain 2 made of metal or rubber is attached to the tire 1.
In order to prevent the tire chain 2 from falling off, the annular fastener 3 is connected to the tire chain 2, and the annular fastener 3 is tightened at predetermined intervals of the annular fastener 3 to prevent the tire chain 2 from falling off. The tightening tool 4 is locked.

FIG. 16 shows in detail the state before the tightening operation of the tightening tool 4, and has locking rods 4a, 4a at the outer end which are locked to the annular tightening 3 side of the tire chain 2. Two U-shaped pieces 4b, 4b and these two U-shaped pieces 4b, 4
b is arranged in a direction in which the U-shaped mouth portions 4c, 4c can face each other, and the inner ends of the U-shaped pieces 4b, 4b are formed by interposing discs 4e having shafts 4d, 4d respectively. .

FIG. 17 shows the tightening operation state of the tightening tool 4 in detail. The tip end 5a of the tool 5 is inserted into a fitting hole 4f formed in the central portion of the interposition board 4e to intervene. Board 4e
When the U-shaped pieces 4b, 4b of the U-shaped pieces 4b, 4b are engaged with each other by rotating the
The shaft attachments 4d and 4d to the interposer board 4e are formed by the U-shaped piece
B-shaped mouth portions 4c, 4 of the U-shaped pieces 4b, 4b from the line connecting the connecting portions 4g, 4g of the locking rods 4a, 4a.
It is formed so as to be located inside c.

Further, as another conventional example of the anti-skid device for a vehicle, there is, for example, one disclosed in Japanese Patent Publication No. 5-58921. This will be described with reference to FIG.
FIG. 19 is a front view of the tightening tool main body in the vehicle anti-skid device, FIG. 19 is a side view of the same portion in section, FIG. 20 is a view showing a usage state of the tightening tool before tightening, and FIG. It is a figure which shows a state.

In these figures, 7 is a plate made of metal or the like which forms the main body of the tightening tool, and the plate 7 is used as a core material and is molded 8 with synthetic rubber or soft synthetic resin to form the upper left corner and the lower right corner in FIG. A lock projection 8a is formed on the lock hook 8a, and as shown in FIGS. 20 and 21, the hooks 9 and 9 that engage with the connection projections 12 and 12 of the tire chain C are freely rotatable at the left and right positions of the tightening tool body. Holes 10, 10 that are engaged with the front and back are formed so as to penetrate therethrough, and further three holes of a tool for rotating the tightening tool body are fitted into the center part of the tightening tool body and the left and right positions thereof. 1
1, 11, 11 are formed to penetrate the front and back.

Then, as shown in FIG. 20, the hooks 9, 9 locked to the tightening tool body are locked to the connecting projections 12, 12 of the tire chain C. Next, the holes 11, 11, 1
When the three fasteners of the tool are fitted to 1 and the tightening tool main body is rotated clockwise, the connecting projections 12, 12 of the tire chain C are pulled by the hooks 9, 9 as shown in FIG. The tire chain C is tightened so that it does not fall off.

[0008]

However, the anti-skid device for a vehicle disclosed in Japanese Utility Model Publication No. 48-39282 has U-shaped pieces 4b, 4b of the tightening tool 4 in the tightening state shown in FIG. The shaft attachments 4d, 4d to the interposer board 4e of the U-shaped pieces 4b, 4b are larger than the line connecting the connecting portions 4g, 4g of the U-shaped pieces 4b, 4b and the locking rods 4a, 4a. Although located inside the U-shaped mouth portions 4c, 4c, the shaft attachments 4d, 4d are connected to the U-shaped pieces 4b, 4b and the locking rods 4a, 4a by the vibration of the tire or the like. When it comes to be located outside the U-shaped mouth portions 4c, 4c from the line connecting the portions 4g, 4g, as shown in FIG. 15, the tightened state is released and the tire chain 2 falls off. There was a fear.

Further, in the vehicle anti-slip device disclosed in the above Japanese Patent Publication No. 5-58921, the elastic body is made of metal 7 or the like plate 7 as a core material, and molded by synthetic rubber or soft synthetic resin. Lock protrusions 8a are provided at the upper left corner and the lower right corner, and the tire chain C is provided at the left and right positions of the tightening tool body.
Of the hooks 9, 9 that are locked to the connecting projections 12, 12 of FIG. Since the holes 11, 11 and 11 into which the three claws are fitted are formed, the manufacturing thereof is troublesome and the manufacturing cost is high. Further, when the connecting projection of the tire chain C is cut, the metal projection The plate 7 may seriously damage the vehicle.

Further, in order to prevent the hooks 9 and 9 from moving over the lock protrusions 8a and 8a so as to rotate, if the lock protrusions 8a and 8a are raised, the hooks are set when the tightening tool is set in the tightened state. There is also a problem in that it is difficult for 9 and 9 to set over the lock protrusions 8a and 8a.

[0019]

As described above, according to the present invention, the substantially rectangular rigid plate, the mounting holes formed in the diagonal portions thereof, and the base ends bent in the substantially U-shape in the respective mounting holes. When the hook body is rotatably penetrated from the back side of the rigid plate and a hook portion is formed at the tip end, and the hook body is rotated to the other diagonal part on the back side of the rigid plate. A locking projection formed to easily get over the inclined portion after easily overcoming the inclined portion, and a fitting portion formed so that the tip of a tool for rotating the rigid plate can fit in the central portion on the surface side of the rigid plate. A vehicle anti-slip device comprising a joint lock body consisting of: and a non-slip member provided with a joint lock body attachment portion on the outer side of the tire when mounted, the joint lock body attachment portion of the anti-slip member Attach and detach the hook part of the joint lock body to That the anti-slip member can be tightened and attached to the tire, the base end portion of the hook body of the joint lock body can be detachably and rotatably penetrated into the mounting hole of the rigid plate, and the joint lock body The hook portion of the hook body is bent so as to be substantially orthogonal to the base end portion and parallel to the outer side surface of the tire. Since the ribs for reinforcing the parts are provided and the protrusion for mounting direction is provided on one side of the rigid plate of the joint lock body, the structure is simpler than the conventional product and the manufacturing cost is low. In addition, since the operability is good, the tightening of the anti-slip device can be performed reliably at all times and easily for women and women, and it is very easy to put on and take off, and the anti-skid device The strength of the part is also strong,
It can be used for a long time without fear of being damaged by delusion. Further, since the hook portion of the hook body is bent so as to be orthogonal to the base end portion and parallel to the outer side surface of the tire, it is possible to easily and surely lock and tighten the slip stopper. In addition, it is possible to prevent rattling of the joint lock body and damage to the outer surface of the tire due to contact with the outer surface of the tire due to deformation of the tire as the vehicle travels. If necessary, the hook body may be detachable at its base end, so that a hook body having a different length corresponding to the size of the tire can be used. In addition, a rib for preventing hook contact and reinforcing the fitting portion is provided on the rear side of the rigid plate, so that it is possible to prevent a collision (collision) between the hooks when the cable is tightened (in a folded state), and It is also possible to reinforce the bottom of the fitting part for tool fitting, and to provide the mounting direction indication projection on one side of the rigid plate to attach the joint lock body to the cable (orientation). ) Can be easily confirmed.
