Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to an anti-slip net for tires.

(Prior art) B shown in Fig. 7 is an anti-slip net for tires with a conventional structure, and this anti-slip net B is made of a wire material formed by coating synthetic rubber around a high-tensile core material. The net is fitted into the forming mesh groove of a vulcanizing press mold, and then press-molded while the anti-slip net body inside the vulcanizing press mold is vulcanized.

The above-mentioned anti-slip net B is long in the overall length direction as shown in the figure, but since it is conventionally press-formed in a press mold as described above, the press mold itself is long and large like the anti-slip net B, and its Manufacturing costs are also becoming more expensive.

In addition, if the conventional anti-slip net B main body breaks off at any part due to progressive wear,
Even if other parts are normal, it becomes unusable.
I had to replace it with a completely new one.

(Technical Issues) The technical issues of the present invention are to reduce the manufacturing cost of the anti-slip net and to provide partial replaceability to the anti-slip net, thereby making it possible to reuse the anti-slip net if it breaks. In addition, the purpose is to make the anti-slip net adaptable to tires of various sizes.

(Means for Solving the Technical Problems) The technical means taken by the present invention to solve the above problems is to braid a basic net body and an adjustment net body that are appropriately shorter than the outer circumference of the tire, and It is characterized in that an appropriate number of adjusting net members are configured to be freely connectable to an appropriate number of adjusting net members.

(Function) According to the above means, an appropriate number of basic net members and an appropriate number of adjusting net members are interconnected to form an anti-slip net according to the size of the tire.

The basic net body and the adjusting net body constituting the anti-slip net are divided at mutually connecting parts.

(Effects of the invention) As described above, the present invention has a configuration in which an appropriate number of basic net bodies and an appropriate number of adjustment net bodies can be freely connected, so that the press mold for molding each net body can be downsized, and the anti-slip net can be made smaller. Not only can manufacturing costs be reduced, but even if a part of the non-slip net is cut off during use, it can be continued to be used by simply replacing the cut part. It has the advantage of significantly reducing maintenance costs compared to conventional anti-slip nets, which require replacing with a new one when a section is cut, while also providing an appropriate number of basic net members and an appropriate number of adjustment net members. By combining and connecting these, it is possible to adapt to tires of various sizes.

Thus, the intended purpose can be achieved.

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

The dimensions such as length, width, and thickness are appropriately set in consideration of conditions such as the diameter and width of various tires.

Adjustment net body b is made of the above-mentioned wire material and has hooks 1, 1' on both sides and connecting bands 4, 4 on both ends, similar to basic net body a, and its size, i.e. Dimensions such as length, width, thickness, etc. are appropriately set in relation to the size of the basic net body a and the tire to be mounted.

In order to interconnect the basic net body a and the adjustment net body b formed as described above, both nets a and b must be connected to each other.
The connecting bands 4, 4 on one end side are aligned, and the connecting fittings 5, 5 are caulked and fixed between both sides of both connecting bands 4, 4, respectively, and each hook is attached to each hook part 1 on the inside. The tightening rope 3 is connected along the entire length of the metal fitting 2.

Connectors 6, 6 are attached and fixed to one end of the anti-slip net _A1 , that is, to both sides of the connection band 4 on the open side of the basic net body a or the connection band 4 on the open side of the adjustment net body b. .

To attach the anti-slip net _A1 , wrap the anti-slip net _A1 around the tire D as shown in Figure 2.
The connectors 6, 6 at one end are hooked to the connecting band 4 at the other end to connect them, and then the ends of the tightening rope 3 inside the net are connected to each other, and the hooks 2' at the outer edge are connected to each other. A rubber band (not shown) is hooked along the tire so that the anti-slip net _A1 is brought into close contact with the tire surface D.

FIG. 3 shows a second embodiment of the present invention, in which an appropriate number of adjusting net bodies b are freely connected to a plurality of basic net bodies a each having an anti-slip net _A2 formed in the same shape. It shows.
