Description

[Detailed description of the invention] The present invention relates to a vehicle anti-slip device that is used by being attached to the tires of automobiles, etc., and its purpose is to ensure that the end of the cable can be easily engaged, is strong, and is suitable for use in vehicles. The engaging part does not easily come off due to vehicle vibrations, etc., and the tensile force acting on the cable can be sufficiently buffered at this part, maintaining the durability of the cable, and it has excellent replaceability and is easy to replace. The cables can be connected in multiple stages, and the length of the cables located inside the wheels can be easily adjusted, providing excellent operability. Moreover, there is no need for a long jig for tensioning the cable during production, and the entire processing equipment is miniaturized and simplified, making it easy to manufacture at low cost and with excellent workability. To provide an anti-slip tool that can be easily and accurately attached to and removed from a tire.

The present applicant previously developed anti-skid devices for vehicles such as those disclosed in Utility Application No. 58-59732 and Utility Model Application No. 59-55963. Because it was an engaging member, the part easily came off, and it was not possible to sufficiently buffer the tensile force acting on the cable, and in particular, the cable located on the inside of the wheel did not adjust to the outside diameter of the wheel. Because the cable was formed in such a way that the end of the cable could be tightened and adjusted as appropriate, it not only took time to adjust and had poor operability, but also caused the cable end to catch on a part of the vehicle body and break when the cable became loose. In addition, the latter, like the former, easily disengaged the end of the cable, and was unable to sufficiently buffer the tensile force acting on the cable. Because the cables located inside the wheels were formed of one continuous piece, when manufacturing anti-slip devices, a long jig was required to stretch the cables in a straight line, and processing equipment was required. The overall size of the project led to various technical problems, including problems with the installation location of the device and workability, and there was a sense of regret that it was not easy to manufacture.

The present invention eliminates these drawbacks, makes it easy and strong to engage the end of the cable, and furthermore, the engagement part does not easily come off due to vehicle vibrations, etc., and the tensile force acting on the cable can be absorbed easily. It provides sufficient cushioning at the inner part of the wheel, maintains the durability of the cable, and has excellent replaceability, making it easy to replace and connecting in multiple stages.In particular, the length of the cable located inside the wheel can be adjusted. It is easy to operate and has excellent operability, there is no risk of the cable end getting caught on a part of the vehicle body after adjustment and the cable is cut, and there is no need for a long jig to tension the cable during production. The entire processing device is miniaturized and simplified without the need for the processing device, and it has excellent workability and can be manufactured at low cost and easily.One embodiment of the present invention shown in the attached drawings will be described in detail below. do.

The present invention is used as described above, but in particular, in the present invention, the cable located inside the wheel is formed in advance to have the same length or slightly longer than the circumference of the tire at the attachment point, and also to extend the length of the tire. It is cut and separated at the ground contact area, each cut and separated end is used as an engaging ring part, and these are mutually locked with a hook-shaped engaging member, so that it can be installed on the tire with a margin, compared to the conventional method. The installation of the cables located inside the wheel, which were considered troublesome, and the fitting of the anti-slip member to the tire can be done easily, accurately and quickly.Moreover, the cut-off end can be adjusted to the size of the wheel as in the past. Instead of adjusting the length by tightening the end of the cable according to the size of the wheel, it is better to prepare several types of hook engagement members in advance according to the size of the wheel and use them selectively. Therefore, it does not take much time to make adjustments like in the past, and it also has excellent compatibility and can be easily replaced, and can be connected in multiple stages, making it very easy to operate. Since the rear end of the cable is caught on a part of the vehicle body, the cable will not be cut, and furthermore, the engagement of both the inner and outer ends of the cable, including the engagement of the end of the cable, can be carried out using a hook-shaped engagement member. Since the ends of the cables can be easily engaged, the ends of the cables can be easily engaged, and the tensile force acting on the cables can be sufficiently buffered at the end without easily coming off due to vehicle vibrations, etc. The length from one cut and separated end of the cable located on the outside of the wheel to the engaged end can be set so that the durability of the cable can be maintained and the length of the cable on the inner side corresponding to the cable is By forming the length from the engagement end of the strip to the cutting separation end of the tire's ground contact area, a sufficient interference margin is provided, and this is secured to the other freely tightenable cutting separation end. Tighten the cables located on the inside of the wheel sufficiently, tighten the inner and outer cables evenly, and attach the anti-slip member to the tire and the inner and outer cables to prevent new tires from wearing out. Since it is designed to be able to be used accurately with any type of tire, there is no risk that the end of the anti-slip member located inside the wheel or the cable may get caught on a part of the vehicle body and be damaged. Even if excessive force is applied while driving,
The tensile force is evenly distributed between the inner and outer cables, which prevents the inner cable from being cut or damaged by tensile force concentrating only on the inner cable, allowing safe driving. There are various effects such as
