Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention provides a rubber non-slip device that connects two parallel side members with a plurality of locking fittings. The present invention relates to a tightening device for a tire anti-slip device for maintaining a rubber anti-slip body in close contact with the tire in a tire anti-slip device formed by connecting bodies.

(Prior Art) Conventionally, when a car drives on snow, tire chains have been attached to the tires or spiked tires have been used to prevent them from slipping, but recently,
For example, in the anti-slip device for tires described in Japanese Utility Model Publication No. 57-113205, a rubber anti-slip band is placed in a ladder shape between two parallel side members (side lobes). Two side members (side lobes) arranged in parallel, such as a connected one (so-called rudder set) or a tire slip prevention device described in Japanese Utility Model Application No. 80-53804. In between, tires in which rubber elastic bodies are connected to cover the outer circumferential surface of the tire (so-called net type tires) are often used. These anti-slip devices are made of rubber anti-slip bodies (rubber anti-slip bands,
The tire was attached to the tire by tightening the side members so that the rubber elastic body came into close contact with the outer circumferential surface of the tire.

(Problem to be solved by the invention) However, as the speed of the car increases and the rotational speed of the tires increases, the rubber anti-slip body swells outward due to the centrifugal force. part is fender
The rubber non-slip body may be damaged due to contact with the tire, or the rubber non-slip body may not be able to maintain close contact with the tire, and the rubber non-slip body may easily slip or twist. This has disadvantages such as accelerating the damage.

[Structure of the Invention] (Means for Solving the Problems) Therefore, the tightening device for the anti-slip device for tires of the present invention includes a plurality of side members arranged between two side members arranged in parallel. The anti-slip tool for tires is formed by connecting rubber anti-slip bodies 10 via a locking fitting C, which includes a locking part 2 for attaching the anti-slip body and a locking part 1 for attaching a tension member. A tensioning member locking fitting A is provided. The locking part 2 for attaching the anti-slip body of the locking fitting A for the tension member is formed so that it can be freely locked in the lock hole 11 or the lock part 12 of the anti-slip body 1o. Locking part 1 for attaching tension member of locking fitting A
is formed so that the annular rubber tension member B can be freely locked. Then, by forming the tension member locking fittings A so that they are directed toward the center of the tire T by the elastic force of the annular rubber tension member B, the above-mentioned problems can be easily solved. I did it like that.

(Function) Thus, the side member locking fitting C is attached to the side member via the side member attachment locking part 5, and the non-slip body attachment locking part 6 locks the non-slip body 10. The anti-slip body 10 is attached to the side member by being engaged with the hole 11 or the engaging part 12, and the tension member locking fitting A is such that the engaging part 2 for attaching the non-slip body is engaged with the non-slip body 10. The rubber tension member B is fixed to the stopper hole 11 or the stopper part 12 and attached to the side member, and the rubber tension member B is fixed to the tension member attachment stop part 1.
The anti-slip body 10 tightens the tire T with the elastic force of the rubber tension member B.
Close to.

(Example) Hereinafter, the present invention will be explained with reference to illustrated examples.

A tensioning member locking fitting A comprising a locking part 2 for attaching a non-slip body that can be freely locked in a locking hole 11 or a locking part 12, and a tensioning member fitting fitting A of this tensioning member locking fitting A. The annular rubber tensioning member B is configured to be freely latched to the stopper 1, and the annular rubber tensioning member B is connected to the tensioning member mounting locking portion 1 of each tensioning member locking fitting A. By locking the rubber tension member B, the plurality of tension member locking fittings A are directed toward the center of the tire T by the elastic force of the rubber tension member B itself, and the anti-slip body 10 itself comes into close contact with the outer peripheral surface of the tire T. It is formed like this.

The tensioning member locking fitting A has a substantially hook-shaped non-slip tube locking part 2 at its tip, and a rubber tensioning member B at its base end.
It is provided with a substantially hook-shaped tension member attachment locking part 1 that can be locked. Note that the tension member locking fitting A shown in the figure is constructed by appropriately bending a single metal wire, but it may also be constructed from a single metal piece that is appropriately bent. . Further, the tensioning member attachment locking portion 1 of the tensioning member locking fitting A may be formed into a substantially annular shape so that it can be slidably fitted onto the rubber tensioning member B (not shown).

The side member locking fitting C has a substantially hook-shaped non-slip body attachment locking portion 6 at its tip, and a substantially annular side member that can be slidably fitted onto the side member at its base end. A locking part 5 for attachment is provided. Although the side member locking fitting C shown in the figure is constructed by appropriately bending a single metal wire, it may also be constructed from a single metal piece that is appropriately bent. . In addition, side member locking metal fittings C
The side member attachment locking portion 5 may be formed into a substantially hook shape that can be freely locked to the side member (not shown).

By the way, the tension member locking fitting A in the illustrated example is designed to prevent the rubber tension member B from coming into contact with the side member locking fitting C or the side member lever as much as possible. The distance between the side member attachment locking portion 2 and the body attachment locking portion 2 is formed to be shorter than the distance between the side member attachment locking portion 5 and the non-slip body attachment locking portion 6 of the side member locking fitting C. However, the side member attachment locking part 5 of the side member locking fitting C
It may be formed so that it is longer than the interval between and the locking part 6 for attaching the anti-slip body, or it may be formed to have the same length. Further, the tensioning member locking fitting A is formed so that the opening direction of the tensioning member attachment locking part 1 and the opening direction of the anti-slip body attachment locking part 2 are shifted to form a substantially S-shape. However, it is also possible to form a substantially elongated C-shape in which the opening directions thereof are opposite to each other.

Further, the locking part 2 for attaching the anti-slip body may be formed into a single hook shape as shown in the illustrated example, or although not shown in the figure,
The hook-shaped locking part 2 for attaching the anti-slip body is bifurcated (approximately V-shaped).
It may also be formed by disposing it in the same direction.

That is, the shape and material of the tension member locking fitting A as a whole, the specific structure, shape, dimensions, etc. of each of the tension member attachment locking part 1 and the anti-slip body attachment locking part 2 are limited to the illustrated example, etc. You can freely set the settings as appropriate without being affected.

The rubber tension member B is made of an appropriate rubber material and has an annular shape with a circular cross section.
0 is attached to the tire T, and when the rubber tensioning member B is locked to each of the tensioning member attachment locking parts 1 of the plurality of tensioning member locking fittings A, the elastic force of the rubber tensioning member B is applied to the tensioning member. Locking metal fitting A
The anti-slip body 10 is set to be in close contact with the outer peripheral surface of the tire T by applying tension so as to move each of them toward the center of the tire T.

A plurality of bulging portions B1 as shown in FIG. 5 are formed at predetermined positions of the rubber tensioning member B, and the pair of bulging portions B1 are used to lock the tensioning member locking fitting A for mounting the tensioning member. It may be formed so that the tensioning member locking fitting A can be easily positioned with respect to the rubber tensioning member B by sandwiching the portion 1.

In addition, a plurality of rubber tension members B are used to lock the tension member locking fittings A at appropriate intervals, so that each of the tension member locking fittings A is moved toward the center of the tire T. It's okay to be nervous so you can move.

By the way, the specific configuration, shape, dimensions, number, material, etc. of the rubber tension member B are not limited to the illustrated example (they can be set freely as appropriate).

In addition, when the side rope D1 is used for the side member, a synthetic resin pipe into which the side lobe D1 is fitted is provided between the adjacent side member locking fittings C, so that the side lobe D1 itself can be protected. (See Figure 5). By the way, it is also possible to use wire ropes or chains for the side members.

The present invention is constructed as described above, and its use will now be explained. First, the side lobe D1 is inserted through the side member attachment locking portion 5 of the side member locking fitting C, and the anti-slip body attachment lock is The stopper 6 is inserted into the locking hole 11 of the anti-slip body 10.
Alternatively, by locking with the locking portion 12, the anti-slip body 10 is disposed between the parallel side members. Then, tighten the side lobe D1 by attaching the anti-slip device to the tire T.

In between, there is a so-called ladder set of anti-slip devices for tires (see FIGS. 3 and 4), which is made up of substantially belt-shaped rubber anti-slip bodies 10 connected in a ladder-like manner, and A so-called net-type tire slip formed by connecting a rubber anti-slip body 10 integrally formed between two side members D (side lobes DI) so as to cover the outer peripheral surface of the tire T. It can be used as a stopper (see FIGS. 1 and 2) and other suitable anti-slip devices for tires.

That is, when used as a net-type anti-slip device for tires, the non-slip body attachment locking portion 6 of the side member locking metal fitting C is inserted into the locking hole 11 of the non-slip body 10 or the locking portion 1.

[Effects of the Invention] Accordingly, the present invention is constructed by connecting the rubber anti-slip body 10 between two parallel side members via a plurality of side member locking fittings C. In the anti-slip tool for tires, a tension member locking fitting A is provided, which includes a locking part 2 for attaching the anti-slip body and a locking part 1 for attaching the tension member. The locking part 2 for attaching the anti-slip body is formed so as to be able to be locked in the locking hole 11 or the locking part 12 of the anti-slip body 10, and the locking part 1 for attaching the tension member is formed of an annular rubber. The tension member B is formed so that it can be freely locked, and the elastic force of the annular rubber tension member B directs the tension member locking fittings A toward the center of the tire T. , when the running speed of the car increases and the rotational speed of the tire T increases, the elasticity of the rubber tension member B itself prevents the rubber anti-slip body 10 from expanding outward due to the centrifugal force. The force can be stopped by directly acting on the rubber non-slip body 10 through the tension member locking fitting A, and the rubber non-slip body 10 can be reliably prevented from coming into contact with a fender or the like and being damaged. become. In addition, the closeness of the anti-slip body 10 to the outer circumferential surface of the tire T is further increased, making it difficult for the anti-slip body 10 to shift relative to the tire T or twisting the anti-slip body 10 itself, thereby causing damage to the non-slip body 10 itself. can be reliably prevented.

In addition, the structure of the tension member locking fitting A itself is simplified,
It is suitable for mass production and can be provided at low cost. Furthermore, the present invention can be constructed by simply adding a plurality of tensioning member locking fittings A and rubber tensioning members B to the existing anti-slip device for tires.

In particular, it can be used for all kinds of anti-slip bodies 10 (net type, ladder set), and can be used for all side members D.
(side lobe p1, side wire, chain, etc.) can also be used, making it highly versatile.

Furthermore, since the rubber tension member B and the side member lever are used together, if a strong force is applied, the side member member will surely receive this force, and the rubber tension member B will not break. There is no risk of major deformation until the

By forming the tensioning member attachment locking part 1 of the tensioning member locking fitting A into a hook shape, the tensioning member attachment locking part 1 can be attached to any position such as a side chain. It also becomes easy to change the number of anti-slip bodies 10 according to the size of the tire T, etc.

Furthermore, by forming the side member attachment locking portion 5 of the side member locking fitting C into an annular shape, there is no possibility that the side member attachment locking portion 5 will deviate from the side lobe D1. At the same time, the attachment position of the side member locking fitting C to the side lobe D1 can be freely changed.

Furthermore, by fitting the protective pipe onto the side lobe D1, the side lobe D1 can be reliably protected and the durability of the side lobe D1 can be further improved.
