Description

[Detailed description of the invention] (Field of industrial application) This invention is a tightening part located on both sides of a tire skid device that is attached to a car tire to prevent it from slipping when driving on a snowy road. This relates to a length adjuster for a tire skid that can be attached to the tire to adjust the overall length.This length adjuster is easy to adjust and has been improved so that the hook of the tightening band can be hooked.

(Prior Art) Conventionally, a tire skid device is attached to the tightening parts located on both sides of a tire skid device to adjust the overall length.
The invention of Utility Model Application Publication No. 52-90805 and the invention of Japanese Patent Application Publication No. 56-160206 have been proposed.

Utility Model Application Publication No. 52-90805 is a hook that is attached to the end of the tightening part of a tire skid device, with a hole and an inlet provided at the end of the plate, and a guide connected to the inlet. It consists of a groove and three branch grooves.

The invention disclosed in Japanese Patent Application Laid-Open No. 56-160206 has an insertion opening provided in a plate body, and two accommodation openings of different lengths following the insertion opening.

(Problem to be solved by the invention) None of the above conventional examples has a hole on which the hook of the tightening band is hooked, so when installing the tightening band, avoid that hole and attach the hook. Since the tire had to be hooked, there were cases where the entire tire anti-skid device could not be tightened evenly.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a length adjuster 1 for a tire skid which is attached to the tightening portions 4 located on both sides of the tire skid. A plurality of engaging grooves 1a...1a and a moving groove 1b connecting the engaging grooves 1a...1a are bored, and a tightening band 5 is formed.
Hook 6...Hook hole 1c for hanging 6
It is made by drilling.

(Example) Next, an example of the present invention will be described based on the drawings.

The length adjuster 1 is plate-shaped and has three engaging grooves 1a...1a in which a chain ring or the like of the tightening part 4 of the tire anti-skid tool engages.
A moving groove 1b is drilled through which a chain ring or the like can be moved by connecting the hooking grooves 1a...1a, and a hooking hole 1c for hooking the hooks 6...6 of the tightening band 5 is drilled. It is set up. The lower edge 1d of this hooking hole 1c protrudes toward the front in order to make it easier to hook the hooks 6 . . . 6 of the tightening band 5 from the inside. Further, a circular hole 1e is bored at the end. The engaging grooves 1a...1a and the circular holes 1e are arranged in a straight line, so that the length adjuster 1 always remains straight no matter which engaging groove it engages with.

Note that the circular hole 1e is not necessarily necessary, and the tightening portion 4 is provided within the openings of the engaging grooves 1a...1a and the moving groove 1b.
It is also possible to include both chain rings, etc.

A movement prevention piece 2 is rotatably attached to the end of the length adjustment tool 1, and by closing the movement groove 1b of the length adjustment tool 1, It is designed to prevent movement of the chain ring of the tightening part 4 that is engaged with the engagement groove 1a.

The length adjuster 1 configured as described above is attached to the tightening parts 4, 4 on both sides of the tire antiskid device, and the antiskid device main body 3
...One is placed between each of 3.

Note that the number and locations of the length adjusters 1 to be provided on the tightening parts 4, 4 are arbitrary. Regarding the installation location, in addition to the above-mentioned non-slip body 3... 3, a long hole is bored on the opposite side of the hook hole 1c of the length adjustment tool 1.
The anti-slip body 3...3 may be attached to this elongated hole.

(Function) The present invention is constructed as described above, and in order to adjust the length, the movement prevention piece 2 is rotated to open the movement groove 1b, and the chain ring of the tightening part 4 is engaged from the engagement groove 1a. Remove it, move it in the moving groove 1b, and move it to the other engaging groove 1a.
and rotate the movement prevention piece 2 to move the movement groove 1b.
What is necessary is to close it so that it does not come off from the engagement groove 1a.

To use the tire skid device to which the present invention is attached, first adjust the length to approximately match the tire size before attaching it to the tire, and then attach it to the tire in the same way as before. At this time, for example, if the tire skid tool is short and difficult to connect, the length is increased using the length adjuster 1 at an appropriate location to facilitate the connection operation. After the connection, the length is shortened using the length adjuster 1 to fit the tire. After installation, tighten the tightening band 5
The hooks 6...6 may be hooked onto the hook hole 1c of the length adjuster 1 or the chain ring of the tightening part 4 and tightened.

(Effects of the invention) As described above, according to the present invention, the length of the tire skid device can be easily adjusted, so the tire skid device can be adapted to suit the tire air pressure and the degree of tire pressure reduction. There is.

In addition, a hook hole is drilled in the length adjuster so that the hook of the tightening band can be hooked into the hook hole, so if the tightening part of the tire skid device is a chain, the tightening part The hook of the tightening band can be hooked anywhere on the chain, which has the effect of evenly tightening the entire tire non-slip device. If it is not possible to hook the belt, it is possible to attach a tightening band by arranging several length adjusters at equal intervals on the tightening part.
