Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a device for preventing damage to the side surface of a tire and a tire wheel when a tire chain is installed.

``Prior Art'' In conventional tire chains, consideration has been given only to ease of attachment to tires and grip on snow surfaces, and little consideration has been given to protection of tires and tire wheels. Utility Model Publication No. 34-8808 slightly advocates the elimination of friction from tires, but does not even consider eliminating friction from tires and wheels.

``Problems to be Solved by the Invention'' If tires and tire wheels are damaged, not only will the aesthetic appearance of the tires and tire wheels be impaired, but the balance between the tires will be disrupted during driving. The weight of the tire wheel greatly affects the balance of the tire during driving.

Weights are then attached to the tire wheels to maintain balance. This weight is adjusted in grams. The balance between the tires is that important for high-speed driving. If a tire wheel is damaged by a tire chain, it will affect the delicate balance when the chain is not attached, making stable high-speed driving impossible. In particular, aluminum wheels, which are often used for tires, are easily damaged, so they need to be protected from the standpoint of aesthetics and balance.

Although it is possible to invent a completely new tire chain to protect tires and tire wheels, purchasing a new tire chain wastes the existing tire chain. Although there are technical problems, the conventional iron chain staircase chain is still widely used because it is inexpensive. This invention is intended to be used in existing conventional chains to prevent damage to tires and tire wheels.

"Means for Solving the Problems" In order to achieve the above object, this invention uses a plate-shaped body that is shorter than the diameter of the tire and longer than the tire wheel. A sliding body movable in the radial direction is attached to each plate-shaped body arranged radially, and the end of the tire chain that is moved in the outer circumferential direction and attached to the tire is attached to the sliding body, and the end part of the tire chain that is moved in the outer circumferential direction and attached to the tire is attached to the sliding body. The invention is characterized by a configuration including means.

``Action of the invention'' Plate bodies are arranged radially on the side surfaces of the tire and tire wheel, and the sliding body is moved outward, so that the end of the tire chain attached to the tire can be easily attached to the sliding body. Install.

Thereafter, by providing the sliding body with convergence means, the sliding body moves toward the center and tightly tensions the tire chain.

"Embodiment of the invention" A first embodiment of the invention will be described based on FIGS. 1 to 5.

In the figure, 1 is a tire, 2 is a tire wheel, and a damage prevention device 3 and a tire chain 4 are attached to these 1 and 2.

The breakage prevention tool 3 can be constructed by arranging a plurality of short plate-like bodies 5 radially. The plate-like body 5 has an elongated plate shape, and a plurality of sliding bodies 6 are attached at intervals in the radial direction of the tire, that is, in the length direction of the plate. The length of the plate-shaped body 5 must be shorter than the diameter of the tire 1 and longer than the diameter of the tire wheel 2. This is because if it is longer than the diameter of the tire 1, it will hinder the rotation of the tire 1, and if it is shorter than the diameter of the tire wheel 2, it will not be able to play the role of protecting the tire wheel 2. Although the material of the plate-shaped body 5 does not matter, plastic is optimal in terms of mass productivity, workability, cost, etc.

Two protrusions 7 are provided on both ends of the back surface of the plate-like body 5 along the length direction of the plate-like body 5. These protrusions 7 serve to increase the strength of the plate-like body 5 itself and to enable sliding of a sliding body 6, which will be described later. Further, these protrusions 7 are provided at least in the portion where the back surface of the plate-like body 5 comes into contact with the tire 1 and the tire wheel 2.

Two parallel grooves 8 penetrating from the front surface to the back surface of the plate-like body 5 are bored in the plate-like body 5 along the length direction of the plate-like body 5. However, since the grooves 8 are not required up to the center of the plate-like body 5, a total of four grooves 8 are provided on both sides of the plate-like body 5 with the center thereof sandwiched therebetween.

The central portion 9 of each plate-like body 5 protrudes beyond both side portions of the plate-like body 5 and has a plane parallel to the planes of both side portions. The protruding portions 9 at the center of each plate-like body 5 have different lengths and are joined at the center with a screw or the like 10, so that the three plate-like bodies 5 can be piled up and kept together when not in use.

The reason why the central portion 9 of the plate-like body 5 is made to protrude is to match the tire wheel with a protruding shaft portion. Therefore, for a tire wheel whose shaft portion does not protrude, a plate-like body 5 whose central portion 9 does not protrude can be used.

The sliding bodies 6 are slidably attached to the grooves 8 of the plate-like body 5 by slide guide structures.
Two hook portions 11 and 12 facing inward are provided at the front end and rear end of the surface of the sliding body 6. A part of the tire chain 4 is hooked onto the outside hook part 11,
The inner hook part 12 is a rubber band 1 as a convergence means.
Hook 3. From both sides of the back surface of the sliding body 6, L-shaped legs 14 face inward in the sliding direction of the sliding body 6, sandwiching the portion between the two grooves of the plate-like body 5. Before attaching the sliding body 6 to the plate-like body 5, the legs 14 of the sliding body 6 are made parallel to each other. When attaching the sliding body 6, as shown in FIG. The legs 14 are bent into an L shape so as to face each other.

To attach this damage prevention device 3 to the tire 1,
As shown in FIG. 5, the plate-shaped body 5 joined at the center is spread out and applied to the side surface of the tire 1, and the outer hook portions 11 of the sliding body 6 are hooked to six locations on the tire chain 4.
After that, when a rubber band is hooked on each inner hook part 12 and the six sliding bodies 6 are moved toward the center,
Tire chain 2 is also pulled to the center, and tire 1
Fixed.

According to the above-mentioned embodiment, the plate-shaped body 4 is positioned on the side surface of the tire and the tire wheel, and the tire chain 4 is hooked onto the outer hook portion 11 of the sliding body 6 that has been moved outward. The chain 4 can be installed and protected in the future by simply stretching the rubber band 13 and hooking it on the chain.

Further, FIG. 6 shows a sectional view of a second embodiment of this invention. In this case, one groove 8 of the plate-like body 5 is provided on each side of the plate-like body 5. Corresponding to this, the lower part of the sliding body 6 can also be formed into a cross-sectional shape.

In the above embodiment, a case is shown in which the sliding body 6 is provided with outer and inner hook portions 11, 12, but the structure can be made smaller and simpler by making one hook portion, for example, S-shaped. Moreover, the sliding bodies 6, 6 and the plate-shaped body 3
For this purpose, a sliding structure other than the above two slide guide structures can be adopted.

``Effect of the invention'' As mentioned above, in this invention, a plate-shaped body shorter than the diameter of the tire and longer than the diameter of the tire wheel is applied to the side of the tire, so that the tire chain comes into direct contact with the side of the tire and tire wheel. Since this prevents the tire chain from hitting the tires and tire wheels when the car is running, the tires and tire wheels are not damaged.

If the tires and tire wheels are not damaged,
Not only are these aesthetics maintained, but the mutual balance between the tires is also maintained.
