Description

Description: TECHNICAL FIELD The present invention relates to an anti-skid device that is attached to a tire of a vehicle as an anti-skid on a snowy day or the like.

Conventionally, a chain has been widely used as this kind of anti-skid. However, there are drawbacks that it takes a lot of time to mount the above-mentioned chain on the tire, a considerable noise is generated during traveling, and the road surface and the tire are significantly damaged due to the pressure contact of the chain.

Therefore, in order to solve the above-mentioned drawbacks, Japanese Patent Publication No. 57-53
No. 201 and JP-A-57-186508 have developed anti-skid devices using elastic bodies such as rubber and synthetic resin instead of chains. This non-slip member is generally called a ladder type, and an anti-slip member formed by an elastic body such as rubber or synthetic resin into an inner shape and a required width that can be fitted to the outer peripheral surface and both side surfaces of the tire, a chain, a wire, etc. A connecting member in which fixing metal fittings are caulked and fixed at appropriate intervals, and the antiskid member is fixed to the fixing metal fittings of the connecting member to connect the antiskid member to the tire at appropriate intervals. It is a thing.

However, of the above-mentioned anti-skid devices, in the case of the former,
There is a drawback that the rod-shaped part of the fixing bracket contacts the side face of the tire and damages the side face of the tire.In the latter case, the rod-shaped part of the fixing bracket does not damage the side face of the tire, but the anti-skid member reduces the weight of the vehicle. Both ends of the anti-slip member when added,
That is, as a result of the inner shaped parts that fit on both side surfaces of the tire expanding outward, the rod-shaped part of the fixing bracket hits the inner surface of the fender of the vehicle body or other parts of the vehicle body and damages the anti-slip member itself or the vehicle body. There was a fear of doing it.

The present invention prevents the side surface of the tire from being scratched by minimizing the contact of the rod-shaped portion of the fixing bracket with the side surface of the tire, and prevents the both side ends of the anti-slip member from expanding outward. The rod-shaped part of the fixing bracket is the inner surface of the fender of the vehicle body,
Alternatively, the conventional defect is eliminated by preventing the non-slip member itself or the vehicle body from being damaged by hitting other parts of the vehicle body.

An embodiment of a vehicle anti-skid device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view showing a state in which the anti-skid device of the present invention is mounted on a tire, in which A is a tire, 1 is an anti-slip member,
2 is a rope, a chain, a wire such as a wire, 3 is a fixture, and 4 is a tightening tool.

The non-slip member 1 is made of an elastic material such as rubber or synthetic resin, and has a predetermined narrow width formed by bending the inner shape so that it can be fitted to the outer peripheral surface B and both side surfaces C of the tire A in advance. It may be any tool such as a tool, or a non-slip tool that is flat when not in use, and is bent and attached along the outer peripheral surface B and both side surfaces C of the tire A only when in use. The shape may be I-shape, X-shape, or any other shape.

Thus, the anti-slip member 1 has engaging holes 1a, 1 at both ends thereof.
Two a are drilled, and a projection 1b for guiding and preventing contact is provided between the engaging holes 1a.

Further, in the fixing metal fitting 3, the bent portion obtained by bending the rod into a U-shape is folded back upward to form a line attachment portion 3a, and further, both ends of the rod bent into the U-shape are slidably attached to each other. Stop member 1
The engaging portion 3 is bent in an inverted U shape so as to engage with the engaging holes 1a, 1a, and in a direction opposite to the rope attaching portion 3a.
b, 3b, and the rod-shaped portion between the rope attaching portion 3a and the engaging portions 3b, 3b is bent into a substantially S-shaped side cross section, and the rope attaching portion 3a is caulked to the rope 2. hand,
The fixing metal fittings 3 are fixed to the rope 2 at appropriate intervals. In this case, when the rope 2 (cord) is a chain, as shown in FIG.
This is to be attached by loosely crimping a onto the chain. Further, in order to prevent the rope attaching portion 3a of the fixing metal fitting 3 from shifting to the left or right due to the elongation of the rope 2 or the like, the rope 2 is provided with a bulging portion 2a by embedding a pouring and solidifying agent, a screw, etc. It can also be fixed by crimping so as to sandwich (see FIG. 4).

Next, an example of use of the slip stopper of the present invention will be described.

As shown by the solid line in FIG. 6, the engaging portions 3b, 3b of the fixing member 3 fixed to the rope 2 are positioned on both sides of the projections 1b for preventing guide and contact at both ends of the anti-slip member 1 and fixing them. The metal fitting 3 is strongly rotated in the direction of the arrow so that the engaging portions 3b, 3b of the fixing metal fitting 3 are engaged with the engaging holes 1a, 1a of the anti-slip member 1. Hereinafter, the engaging portions 3b, 3b of all the fixing fittings 3 fixed to the rope 2 in the same manner are replaced with the engaging holes 1a, 1 of the anti-slip member 1.
The anti-slip member 1 is fixed to the two ropes 2 and 2 at appropriate intervals by engaging with a. Then, it is wound around the tire A and both ends of the rope 2 are tightened by the tightening metal fittings 4.

As described above, in the present invention, the bent portion obtained by bending the rod shape into a U-shape is folded back upward to form the rope attachment portion 3a, and further, both end portions of the rod material bent into the U-shape are slid. Stop member 1
The engaging portion 3 is bent in an inverted U shape so as to engage with the engaging holes 1a, 1a, and in a direction opposite to the rope attaching portion 3a.
b, 3b, and the rod-shaped portion between the cord attaching portion 3a and the engaging portions 3b, 3b is bent into a substantially S-shaped side cross section. 3a is a continuous, substantially parallel S-shaped body, and the bar-shaped portion almost never comes into contact with the side surface of the tire as in the conventional product. As a result, the side surface of the tire may be damaged. Even if the both ends of the anti-slip member to which the fixing metal fitting is attached may expand outward, the fixing metal fitting 3 may come into contact with the inner surface of the fender of the vehicle body or another portion of the vehicle body. Since the stopper member itself or the vehicle body is not damaged and the two S-shaped bent portions are integrally formed in parallel in one member, they can be attached to the tire. It's more stable than just one, and therefore more It without said fixed bracket or damage the sides of the tire twisted, there is an effect that can be used for a long time.
