Abstract

PURPOSE:To prevent a slip by fixing a tube on the inner side surface of a frame provided from one side of a tire to the other side, providing a nonslip part at a grounding surface of the frame, and swelling the tube. CONSTITUTION:A frame 1 having a proper resiliency is of such a shape as to profile a cross section of a tire 2 to be attached to the tire 2 from one side to the other side. A tube 3 fixed to the whole inner side surface of the frame 1 is provided, and a valve 4 for letting air in and out is installed in it. The surface of the frame 1, that is a grounding surface, is formed thick or protruded, and a recessed part 6 to install a nonslip part is formed in it. The nonslip part is formed of a base 7 of a size to be tightly contained in the recessed part 6 having a fiber body 8 of natural or chemical fibers densely planted in it, and it is fixed to the frame 1 by screws 9. By supplying air to the tube 3 to swell it only, therefore, a slip can be prevented by action of the nonslip part.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a non-slip device for mounting tires, and more particularly, to a non-slip device for use when driving on snowy or frozen roads, or when starting on a steep slope or in the depths. The invention relates to anti-slip devices that are attached to vehicle tires for this purpose.

[Conventional technology]

Tire chains made of metal, rubber or plastic are used exclusively as anti-slip devices for vehicles for the above purpose.

[Problem to be solved by the invention]

In the case of the conventional tire chains mentioned above, metal fittings, rubber rings, etc. are used to ensure adhesion to the tire, but the adhesion becomes poor, especially when driving at high speeds, resulting in poor running performance and causing noise. In addition, it takes time and effort to put them on, and it is extremely troublesome, especially during the coldest months.

Therefore, the present invention has been developed to provide a highly durable tire mounting system that allows any number of people to easily and quickly attach and detach tires, has excellent adhesion to the tires, does not impede running performance, reliably prevents slipping, and is highly durable. The purpose is to provide a non-slip device for use.

[Means to solve the problem]

The present invention provides a rubber or plastic conductor frame 1 that can be covered from one side to the other of the tire 2 and has a core material made of metal, hard plastic, etc. embedded therein, and the inner surface of the frame 1 is A non-slip tool for mounting a tire, comprising a tube 3 that allows air to enter and exit from the outside of the frame 1, and a non-slip part provided on the ground surface of the frame 1;
Further, a rubber or plastic conductive layer frame 1 is provided which can be covered from one side of the tire 2 to the ground contact surface, and has a core material such as metal or hard plastic embedded therein.
The contact surface of the frame 1 is extended to cover the entire circumference of the tire, and a tube 3 that allows air to enter and exit from the outside of the frame 1 is fixed to the entire inner surface of the frame 1 including the contact surface. The above-mentioned problem has been solved by a non-slip tool for mounting a tire, which has a non-slip part on the contact surface of the first tire.

The cleat is typically made replaceable.

[For production]

After attaching the frame to the tire, when air is supplied to the tube to inflate it, the tube comes into close contact with the tire and is tightened, thereby firmly fixing the anti-slip device to the tire. When the car is running or when getting out of the car, the anti-slip part prevents slipping.

〔Example〕

Preferred embodiments of the present invention will be described with reference to the drawings.

The embodiments shown in FIGS. 1 to 8 are constructed so that the anti-slip device according to the present invention can be attached to a part of a tire.

In the figure, reference numeral 1 denotes a frame made of plastic or rubber having appropriate elasticity, and is shaped to follow the cross section of the tire 2 so that it can be attached from one side of the tire 2 to the other. A thin rod-shaped or thin plate-shaped core material made of metal or hard plastic is embedded in the frame 1 to provide shape retention. 3
is a tube fixed to the entire inner surface of the frame 1 with adhesive, Velcro tape, etc., and a valve 4 for air inflow and outflow.
will be installed. The valve 4 is fixed to a valve mounting hole 5 formed in the frame 1 (Fig. 3).The tire contact surface of the tube 3 is made of fiber in order to better fit the tire and improve adhesion. A mesh may also be attached.

The surface of the frame 10, that is, the ground plane is thickened, or
It is raised and a recessed part 6 for installing the anti-slip part is formed there. The anti-slip portion is usually installed in a replaceable manner. For example, the anti-slip portion may include a fiber body 8 made of natural fiber or chemical fiber on a base 7 having a size that fits tightly within the recessed portion 6.
are closely planted and fixed to the frame 1 with screws 9.

Instead of the fibrous body 8, rubber with appropriate unevenness formed thereon, or
It goes without saying that a plastic anti-slip material may be used, and Figures 6 to 8 show examples thereof.
The central portion is made to protrude in a trapezoidal shape, and a deep groove 11 is formed across the peak 10 of the trapezoid. The one shown in this example is especially used for escape.

The surface of the frame 1 is further provided with protrusions 12 and grooves 13 as appropriate, which serve to enhance the anti-slip effect, reduce noise, disperse and eliminate impact, and the like.

In addition, at the front end and rear end of the surface of the frame 1 in the traveling direction,
A pressing plate 14 may be provided that folds back the end edge of the tube 3 and presses it down from above. An unevenness 15 is formed on the outer end surface of the presser plate 14 in order to disperse the force upon contact with the ground.

In the above configuration, when using this anti-slip tool,
Alternatively, a plurality of them are pushed into the tire 2 and temporarily fixed. At that time, there is no need to jack up the car. Therefore, when air is supplied into the tube 3 from the valve 4 using an appropriate air pump, the tube 3 gradually expands and presses the inner surface of the frame 1 and the contact surface of the tire 2. do. Incidentally, since the frame 1 has shape retention properties and is not significantly affected by the expansion force of the tube 3, most of the expansion force acts on the tire 2. As a result, the tube 3 sometimes gets inside the tread of the tire 2 and tightens the tire strongly.
This anti-slip device is firmly fixed to the tire 2, and the tube 3
It will not come off from the tire 2 unless the inflation force is relaxed. In this way, when starting on a steep slope or escaping from a deep place, the anti-slip portion, the convex portion 12, etc. provide a sufficient anti-slip effect, making it possible to start smoothly. The anti-slip parts should be replaced at appropriate times depending on the state of wear.

In the embodiment shown in FIGS. 9 and 10, the frame 1 is sized to cover the ground contact surface from one side of the tire 2, and the ground contact surface and the tube 3 installed inside the tire 2 are extended. It is wound around the entire circumference (the width does not matter).

). In this case, the anti-slip material such as the fibrous body 8 may be installed all around the circumference or at appropriate intervals.
As shown in the figure, the uneven member and the convex portion 12 may be mixed. Also, air is supplied into the tube 3 from the valve 4 installed in the frame 1, as in the above embodiment. The tube 3 does not necessarily need to be connected all the way around, but may be partially divided, and the portions may be joined with a band or the like when the tire is mounted.

The device according to this embodiment is for driving on snowy roads, etc., and it is necessary to jack up the vehicle when installing it, but the anti-slip effect is of course better than that of the above embodiment.

〔Effect of the invention〕

Since the present invention is as described above, it has a component structure,
It can be installed and removed easily and quickly by any person, and does not impair running performance because it is tightly attached to the tire through the tube.
It is very useful because it does not make any noise and the worn parts can be replaced.
