Description

[Detailed Description of the Invention] The present invention relates to an anti-slip mesh rubber band for automobile tires.

That is, the present invention relates to an anti-slip mesh rubber band for automobile tires that prevents automobile tires from slipping on snowy, frozen, muddy, etc. This invention relates to an anti-slip mesh rubber band for automobile tires that can be reliably attached to automobile tires.

Recently, rubber or plastic anti-slip devices for automobile tires have replaced metal chains in order to prevent noise and reduce damage to road surfaces.
Among these, mesh rubber bands containing diagonal reinforcing fibers are attracting attention because of their excellent anti-slip effect, durability, and especially driving performance.

Conventionally, among these mesh rubber band fasteners, those formed into a ring shape during mesh rubber molding are difficult to attach to an automobile tire without jacking the tire. Rubber mesh with reinforcing fibers has the disadvantage that it is difficult to form into a ring shape, so conventionally, rubber with diagonal cross mesh with reinforcing fibers has been used.
After forming the mesh rubber band into a band shape and wrapping it around the tire, the mesh is sewn together with a connecting piece etc. in contact with the mesh at both ends of the mesh rubber band, and then a hook fitting attached to this connecting piece is used. The hook is attached by tightening it by hanging it on the tightening metal fittings or the attachment rope on both the left and right edges, but these methods have the disadvantage that the hook fitting attached to the connecting piece comes off from the attachment rope while the car is running.

In addition, the conventional mesh rubber band with reinforcing fibers is
A diagonal crossing mesh is drilled in the lower mold, and a rubber string containing reinforcing fibers is embedded in this mesh and vulcanization molding is performed to manufacture the product. The disadvantage is that it requires a lot of work to stretch and bury the mesh, and the ropes for attachment are fixed using a large number of metal fittings to the ends of the mesh on both the left and right edges of the vulcanized mesh rubber band, and the rubber ring for tightening is required. Since a large number of hook fittings are attached to hang the hook, there is a disadvantage that it requires a large amount of fittings and man-hours.

The present invention improves these drawbacks.
That is, as the embodiment of the anti-slip mesh rubber band 1 for automobile tires of the present invention can be seen in the drawings, rope passing holes 4 are provided at the ends of the mesh on both the left and right edges of the diagonal mesh rubber band. , this is where the rope passes through hole 5
A leading mesh 3 that does not have a rope passage hole 4 at one longitudinal end of the mesh rubber band 1 that has a
In an anti-slip rubber band 1 for an automobile tire in which a hook through hole 6 and a hook through hole 7 are symmetrically provided at the other end in the longitudinal direction, the mesh rubber band 1 has a symmetrical leading mesh 3. Hook holes 6 provided symmetrically on the other symmetrical end are passed through from one side to the other to connect both ends of the mesh rubber band 1 to form a ring shape, and the hook hole 7 is fitted. With the hook part of the hook fitting 11, hooking fitting 12, rope tightening hook 13, etc. attached to one end of the rope 8 for use inserted, insert it into the hooking ring 9, etc. of the attachment rope attached to the other end. , the mesh rubber band 1 is attached to an automobile tire by hooking the hook portion.

The upper and lower molds have a diagonal crossing mesh band, rope passing holes 4 at the left and right ends of the mesh on both edges of this mesh band, and a rope passing hole 4 at one longitudinal end of the mesh band. Two middle molds are used to form the rope through hole 5 and the hook through hole 6, and one mold is used for the upper and lower molds. While it is being charged into the mold and used for vulcanization molding, a rubber string containing reinforcing fibers is stretched around the middle mold in a diagonal cross-shaped mesh using another medium mold. Since the preparation method is used in advance, the number of vulcanization steps is small, and rope passing holes 4 are formed at the ends of the mesh on both the left and right edges of the diagonal mesh rubber band shown in FIGS. 1a and 1b. and a rope passage hole 4 at one longitudinal end of the mesh rubber band 1.
It is possible to vulcanize and mold an anti-slip mesh rubber band 1 for an automobile tire, which has a leading mesh 3 having no mesh, a hook-through hole 6 at the other end in the longitudinal direction, and a hook-through hole 7 symmetrically provided therein.

FIGS. 2a and 2b are plan views showing an example of the connection of both ends of an embodiment of the present invention.

An embodiment of the present invention will be explained with reference to this figure as follows.

A predetermined length of attachment rope 8 is connected to the rope passage holes 5 lined up on one side of the aforementioned vulcanized mesh rubber band 1, and a hook fitting 11 is attached to one end of the rope 8 as shown in the figure. Installation, rope ring fixing bracket 10
Fix it with. A rope loop 9 for hooking is formed at the end of the other rope 8 as shown in the figure, and this is fixed with a rope loop fixing fitting 10.

Four to eight rubber ring hook fittings 14 are arranged between the rope passage holes 5 lined up on the other side of the mesh rubber band 1.
The rope passing hole 5 and the rubber ring hook fitting 14 are connected with a nylon rope 8 for attachment of a predetermined length, and the hook fitting 11 is attached to one end of the rope 8. Install as shown in the figure,
It is fixed with a rope ring fixing fitting 10, and a rope loop 9 for hooking is formed at the end of the other rope 8, and fixed with a rope ring fixing fitting 10.

The mesh rubber band 1 is wrapped around the automobile tire so that the attachment side of the rubber ring hook fitting 14 of the mesh rubber band 1 is on the outside of the automobile tire and their centers are approximately aligned, and the mesh rubber band 1 is symmetrical. Hook holes 6 provided symmetrically at the other end of the mesh 3 in the longitudinal direction are passed through from one direction to the other, and both ends of the mesh rubber band 1 are connected to form a tire. After attaching the mesh rubber band 1 in a ring shape to the outer periphery of the tire, the hook fitting 11 attached to the mounting nylon rope 8 that communicates with the rope passage holes 6 on both edges of the mesh rubber band 1 is attached to the inside of the tire. The mesh rubber band 1 is fixed to the tire by inserting it into the hook hole 7 starting from the outside and hooking it onto a hooking rope ring 9 provided on the other side of the rope 8. Next, the rubber ring is hung on four to eight rubber ring hooks 14 attached to the nylon rope 8 for attachment, the mesh rubber band 1 is evenly tightened, and the rubber ring is attached to the tire as shown in FIG.

FIG. 3 shows an example in which a hooking fitting 12 and a hooking fitting 11 are added to the connection part of the mesh rubber band 1 shown in FIG. 2a, and the connection of the attachment rope 8 is changed. The mounting procedure on the tire is almost the same as that shown in FIG. 2a above.

FIG. 4 shows an example of the connection of both ends of an embodiment of the present invention, which is installed in almost the same procedure as the embodiment shown in FIG. 2a described above. The difference is that a hooking rope ring 9 is provided at one end of the mounting nylon rope 8 that is on the outside of the tire, and a rope tightening hook fitting is provided with a surplus nylon rope near the other end as shown in the figure. 13 is wrapped around the tire and connected in a ring shape, the hook portion of the rope tightening hook fitting 13 is inserted into the rope passage hole 5 and the rope ring 9 for hooking is inserted at the other end. The mesh rubber band 1 is tightened and attached to the tire by strongly pulling the remaining nylon rope at the end of the rope tightening hook 13.

The anti-slip mesh rubber band for automobile tires according to the embodiments of the present invention shown above has the following advantages.

(b) Since this is a molding method in which two middle molds are used to form the rope passage hole 5 and are used alternately for vulcanization molding and preparatory molding, the number of molding steps can be reduced.
