Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an anti-slip net for tires, in particular, a connecting band provided at one end of the net body is passed through a connecting part at the other end to connect the net, and each of the nets is hung. This invention relates to an improvement in an anti-slip net for tires which is hooked to a rubber band with a fastener.

(Prior Art) As shown in FIG. 6, a conventional non-slip net of this type has a connecting band 32 at one end of the non-slip net main body 31 that protrudes both inside and outside. Both inner and outer connecting parts 33a and 33b are provided on both the inner and outer sides of the other end to connect the inner and outer sides 32a and 32b of the connecting band 32, and when installed, the outer connecting part 33b and the The outer part 32b of the connecting band 32 inserted into the outer connecting part 33b is attached to each rubber band hook 3 attached to the outer edge of the anti-slip net main body 31.
4 to a ring-shaped rubber band (not shown) that is hooked and attached via hooks 36 and 37,
Due to the tension of the rubber band, the outer part 3 of the connecting band 32
2b and the outer connecting portion 32b toward the tire outer surface side, the outer portion 32b of the connecting band 32 is prevented from coming off, and the anti-slip net B is brought into close contact with the tire outer peripheral surface.

However, it is desirable that the outer part 32b of the connecting band 32 is stably hooked into the outer connecting part 33b without shifting, but the outer part 32b of the connecting band 32 and the outer connecting part 33b are Since they are separately hooked to the rubber band by hooks 36 and 37 similar to the hook 34 for the rubber band, the mutual positions of both 32b and 33b are likely to shift, and the outer portion 33b of the connecting band 32 is held while traveling. There was a possibility that the rubber band 35 would not only be displaced or turned inside out due to the impact force, but also come off from the rubber band 35.

Further, the latching fittings 36 and 37 are overlapped and latched together to a rubber band, but this latching operation is somewhat time-consuming.

(Technical Problem) The present invention was devised in view of the above-mentioned problems of the prior art, and it connects the connecting band provided at one end of the net main body through the connecting part at the other end, and connects each net body. In an anti-slip tire net that is hung on a rubber band with a latching fitting, one latching fitting can be used to hang three points: the outer part of the connecting band, the outer connecting part of the connecting part, and the rubber band. The first purpose is to lock the outer portion of the connecting band and the outer connecting portion of the connecting portion so that their mutual positions do not shift.

In addition, if only one latching fitting is used, both the outer part of the connecting band and the outer connecting part of the connecting part cannot be latched to the latching fitting in advance, and at least one of them must be simply latched. Since it is easy to come off, the second purpose is to prevent it from coming off at the same time as the first purpose above.

(Means for Solving the Technical Problem) The means taken by the present invention to solve the above-mentioned technical problem is that a connecting band is provided at one end of the non-slip net main body and protrudes in both the inside and outside directions, and the non-slip It is equipped with both inner and outer connecting parts that insert and connect the inner and outer sides of the connecting band to both the inner and outer sides of the other end of the net main body, and when installed, the outer connecting part and the outer side of the connecting band inserted into the outer connecting part, An anti-slip net for tires that is hooked to a ring-shaped elastic band that is hooked along the outer edge of the anti-slip net body via a hook, the hook being attached to the elastic band side of the body. A band hook part for hanging the elastic band is formed at the end, and a connecting band hook part for hanging the outer part of the connecting band is formed at the end on the side of the non-slip net body, and a connecting band hook part for hanging the outer connecting part. A fixing part to be fixed by caulking is formed in parallel at a predetermined interval in the overall length direction of the anti-slip net body, and the connecting band hook part is at the same level as the fixing part and its insertion opening, and The reason is that the whole part is made longer than the other parts.

(Function) According to the above means, the fixing portion of the latch is caulked and fixed to the external connecting portion of the anti-slip net main body. By hooking the outer part of the connecting band inserted into the outer connecting part to the connecting band hook part during installation, the outer part of the connecting band and the outer connecting part are always maintained at a predetermined distance from each other. By hooking the elastic band to the band hook part of the hook, the elastic band is pulled toward the center of the tire while maintaining the mutual spacing.

Further, the outside portion of the connecting band that is hooked to the connecting band hook portion is maintained in a hooked state to the hook portion due to the long stroke of the hook portion as well as the tensile force during running.

(Effects) The present invention as described above connects the connecting band provided at one end of the net main body through the connecting part at the other end, and each of them is hooked to a rubber band with a latch fitting. In the locking net, the outer part of the connecting band, the outer connecting part of the connecting part, and the rubber band can be latched in three places with one latching fitting, so the outer part of the connecting band and the outer connecting part can be hung together. The hook part for the connecting band of the latch fitting and the fixing part always hold the anti-slip net at a predetermined interval in the overall length direction of the main body, and the net is connected in an appropriate state even while traveling. One of the objectives is to completely prevent the connecting band from shifting or being turned inside out due to impact force while driving.

In addition, since the hooks for hooking the outer part of the connecting band and the outer connecting part to the elastic band were integrated into one, the work of hooking both parts to the elastic band became easier. It is possible to reduce the number of latching fittings and the labor of installation work.

Furthermore, if the hook is used as one as shown above, it is not possible to hook both the outer part of the connecting band and the outer connecting part of the connecting part to the hook in advance, and at least one of them is simply hooked. However, in the present invention, the outer part of the connecting band that is hooked to the connecting band hook part is not only stopped by the tension force during running but also due to the long stroke of the hook part. Since the state of hooking on the hook is maintained and there is no chance of it coming off, the second objective can be fully achieved at the same time as the first objective, which is very useful.

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