Description

[Detailed description of the invention] [Field of industrial application] The present invention is a tire chain used when automobiles run on snow, that is, a tire chain consisting of left and right side chains and a number of cross chains connecting both side chains. , relates to a hook for attaching to a tire using a band (rubber band or coil spring band).

[Conventional technology]

A conventional tire chain hook, as shown in FIG. 1, is composed of a main body part a, a side chain hook part b, and a band ring part c.

[Problem that the invention attempts to solve]

As is well known, as a tire chain band, an endless type band and a non-endless type band having a locking function at both ends are used. Although there is no problem in the case of a non-endless band, the endless band cannot be used, and thus the user is forced to choose between using the non-endless band.

Also, in order to enable the use of both bands, it may be possible to make the ring part c into a hook shape, but if the ring part c is simply made into a hook shape using a rigid material such as metal, the hook shape cannot be formed. There remains a problem with the size of the opening, that is, if the opening is made larger than the diameter of the band, it will be easier to insert the band, but if the band does not have enough tension, it may come out through the opening; If the diameter of the band is smaller than the diameter of the band, it is easy to imagine that the band cannot be inserted.

[Means and actions for solving problems]

A main body plate made of synthetic resin and having a hook part for a side chain at one end; a band hook-shaped part having a hanging plate with a hinge function at the other end; and a locking plate for locking the hanging plate. It consists of a
With this configuration, the band is inserted between the hook-shaped part for the band and the locking plate part, and then the locking plate is hooked on the locking plate part to prevent the band from coming off. This makes it possible to use both types of bands, including endless bands.

〔Example〕

2 is a side view, and FIG. 3 is a front view, where 1 is a main body plate part, 2 is a side chain hook part, 3 is a band hook-shaped part having a hanging plate 31 with a hinge function, and 4 is a hanging part. A locking plate portion for locking the stopper plate 31 is shown, and these plates are made of synthetic resin having heat resistance, impact resistance, and corrosion resistance, such as polycarbonate, polyamide, etc. It is integrally molded using molding means using materials such as nylon (trade name), polyester, etc. Further, the hinge function of the hanging plate 31 is provided by a well-known technique when the material is made of synthetic resin, for example, by using uneven stripes; 32 is the hinge portion.

Incidentally, reference numeral 33 denotes a portion formed above and below the hinge 32 where the outer side of the wheel or the inner side of the tire comes into contact, and although it is shown in a planar shape in the drawing, it can also be in a gentle arc shape. 34 is a reinforcing rib.

In the configuration described above, with the locking plate 31 fully opened along the imaginary line, an endless band or non-endless band made of rubber or a coil spring is inserted between the band hook-shaped portion 3 and the locking plate portion 4. It is inserted and then used by locking the locking plate 31 to the locking plate portion 4.

[Effects of the invention] Since the present invention is constructed as described above, it can produce the following effects.

() It can be used for both types of bands, endless bands and non-endless bands.

() Desorption of the band can be well prevented.

() Since the entire aluminum wheel is made of synthetic resin, damage to the aluminum wheel can be avoided when the aluminum wheel comes into sliding contact with the aluminum wheel.
