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 of an elastic body such as rubber or synthetic resin into an inner shape that can be fitted to the outer peripheral surface and both side surfaces of the tire and a required width, 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 as to fit 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 two engaging holes 1a, 1a with side opening notch grooves 1b, 1b at both ends thereof, and at the upper part of the engaging holes 1a, 1a. The inner side surface is provided with tire contact preventing protrusions 1d, 1d for preventing the upper end portion of the fixing fitting 3, which will be described later, that is, the non-slip member mounting portion 3b from coming into contact with the side surface C of the tire A. .

The fixing metal fitting 3 is formed by bending a bar material into an O-shape and bending the upper end thereof in a horizontal direction or by bending it downward in an inverted U-shape to form a non-slip member mounting portion 3b and a lower end. Is bent upward in a U shape, and is bent in the opposite direction to the anti-slip member attachment portion 3b to form a rope attachment portion 3a, and a rod-shaped portion between the rope attachment portion 3a and the anti-slip member attachment portion 3b is formed. The rope 2 is bent into an S-shape in a side cross-section, and the rope 2 is attached to the rope attaching portion 3a.
Are fixed by caulking, and the fixing fittings 3 are fixed to the rope 2 at appropriate intervals. When the rope 2 (cord) is used as a chain, the cord mounting portion 3a of the fixing metal fitting 3 is loosely wound around the chain for mounting as shown in FIG.

The thickness of the both ends of the anti-slip member 1 according to the present invention is set to be slightly smaller (thinner) than the space 1 between the two S-shaped portions 3c, 3c of the fixing member 3 so that the anti-slip member 1 is fixed. At the time of attaching to the metal fitting 3, the end portion of the anti-slip member 1 is twisted as shown by the dashed-dotted line 4 in FIG. 4 and inserted between the S-shaped portions 3c and 3c of the fixing metal fitting 3, which is shown by the solid line in the figure. Although it can be easily attached by returning and engaging and attaching, the thickness of both ends of the anti-skid member 1 does not necessarily have to be thinner than the interval between the S-shaped portions 3c, 3c. Alternatively, even if it is thick, it can be engaged and attached by compressing it by utilizing its elasticity.

Further, in the case of the rope 2, the cord attaching portion 3a of the fixing metal fitting 3
In some cases, a bulge portion 2a made of a screw or a coagulant may be formed between the S-shaped portions 3c and 3c so that the rope does not move to the left or right due to the elongation of the rope 2.

From the above configuration, the structure of the present invention is simple,
Of course, in the present invention, the bar material is bent into an O shape, and the upper end thereof is bent in the horizontal direction or is inverted downward. It is bent into a U-shape to form an anti-slip member mounting portion 3b, and the lower end is further bent upward into a U-shape, and is further bent in a direction opposite to the anti-slip member mounting portion 3b to form a line attachment portion 3a. Since the rod-shaped portion between the cord attaching portion 3a and the anti-slip member attaching portion 3b is bent into the substantially S-shaped portions 3c, 3c in side cross-section, the entire fixing metal fitting 3 is the cord attaching portion 3a. The non-slip member mounting portion 3b forms two substantially parallel S-shaped bodies that are integrally connected to each other, and the stick-shaped portion almost never comes into contact with the side surface of the tire as in the conventional product. Three
Since the rod portion on the b side is located on the outer surface side of the anti-skid member 1, there is no contact with the tire side surface, and as a result, there is little risk of damaging the tire side surface, and the anti-slip member to which the fixing metal fitting is attached is attached. Even if both side ends of the member expand outward, the fixing metal fitting 3 may hit the inner surface of the fender of the vehicle body or other parts of the vehicle body to damage the anti-slip member itself or the vehicle body. In addition, since the S-shaped bent portion is formed integrally by two members in parallel in parallel with each other, the attachment to the tire is more stable than a single member. Therefore, there is an effect that the fixing fitting is not twisted due to the expansion and contraction of the tire and the side surface of the tire is not damaged, and the tire can be used for a long time.

In the present invention, the ends of the bar member bent into an O shape can be integrally connected by spot welding or the like.
