Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip belt which is detachably mounted on a tire of an automobile on a snowy road, an ice barn or the like.

[0002]

2. Description of the Related Art Conventionally, as this kind of anti-slip device of the tire, there are a number of horizontal chains connected in a ladder shape between two parallel vertical chains made of a metal chain, or a synthetic resin chain. It is known that a large number of horizontal chains are connected in a truss shape between two parallel vertical chains, and in use, the tool is passed around the outer peripheral surface (ground contact surface) of the tire, After connecting both ends of the vertical chain, the rubber string ring positioned on the side of the tire and the vertical chain are radially connected by a number of links.

However, since none of the above-mentioned anti-skid tools have elasticity, when the both ends of the vertical chain are connected to each other when the tire is mounted on a tire, the vertical chain may be tarnished. When the rubber string ring expands due to centrifugal force at the time of high-speed rotation of the tire, the thickness increases, thereby generating noise when the vehicle is running, and the unevenness created by each of the horizontal chains on the outer peripheral surface of the tire causes vibration. generate. Furthermore, the former has a disadvantage of skidding, and there is a danger of slipping when braking when both are grounded on a surface without a side chain.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a non-slip belt which does not give rise to a thickening when mounted on a tire, thereby suppressing noise.

It is an object of the present invention to provide a non-slip belt which suppresses vibration by eliminating irregularities generated on a tire surface and slightly stops skid and slip during braking.

Further, the "joining" of the non-slip piece to the belt includes bonding, sewing, so-called magic tape joining, a combination thereof, and the like. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A non-slip belt (1) shown in FIG. 1 is an example in which a large number of non-slip pieces (4) are joined to an elastic belt (3) composed of an end belt-like belt body (2). The main body (2) is a band made of a flexible and stretchable elastic synthetic rubber sheet, the width of which is slightly larger than the width of the outer peripheral surface of the tire to be mounted, and the length of which is slightly shorter than the outer circumference of the tire. On the left and right sides of the belt body (2), a large number of trapezoidal knob pieces (5) of the same material are respectively extended at small intervals, and at the tip of each of the knob pieces (5), The leading end is turned back and sewn to form a drawn string passing hole (6).

In order to removably connect both ends of the belt body (2), one of the fasteners of the fastener consisting of the locking portion and the locked portion is connected to one end of the belt body (2) and the other is engaged. The stop portion is provided at the other end of the belt body, respectively.As an example, a so-called key piece having a large number of flexible keys on the surface and a loop piece having a large number of flexible loops on the surface, Using a magic fastener, a fastener locking portion (7a) made of a key piece is attached to one end of the belt body (2), and a fastener locked portion (7) made of a loop piece is attached.
b) is attached to the other end of the belt body.

The elastic squeezing cords (8) and (8) are made of rubber cords in this embodiment, and have a hook (9a) having a hook at one end and a receiving member (9a) having a ring at the other end. Each is attached.

The anti-slip pieces (4) are formed on the surface of a flexible base sheet (10) made of an aluminum alloy foil in this example, as shown in FIG.
Are tightly adhered to the entire surface with an adhesive. In this example, this is cut into a substantially rectangular sheet having substantially the same width as the belt body (2) and an appropriate length (in this example, twice as long as the width). A large number of the non-slip pieces (4) are joined to the outer surface of the belt body (2) so as to be adjacent to each other along the longitudinal direction of the belt body to form a series of non-slip materials. I have. In this example, in the present embodiment, the back surface of the non-slip piece (4) is bonded to the outer surface of the belt body (2) with an adhesive, and then both ends in the longitudinal direction of the non-slip piece (4) are attached to the belt body (2). Sewing (12), (12).

One end of the belt body (2) of the anti-slip belt (1) is extended over the outer peripheral surface of the automobile tire (T) by pulling both ends of the belt body (2) toward each other and extending them. Is locked to the fastener locked portion (7b) at the other end, whereby the belt body (2) is wound around the tire outer peripheral surface in a pressed state. In this way, the belt body (2) and the non-slip pieces (4) are stretched without tension.

Next, as shown in FIG. 4, on each of the left and right sides of the belt body (2), the elastic strips (8) and (8) are elastically folded while folding the knob pieces (5). Through holes (6) for each knob piece (5) ...
... in order, and at the final position, the drawstring (8),
(8) is engaged with the hooks (9a) and (9a) at one end to catches (9b) and (9b) at the other end in an extended state. Thus, on both sides of the tire, each knob piece (5) ...
(5) are held in a state where the center of the tire is pulled to the side by the elastic drawstrings (8) and (8), whereby the belt body (2) is pressed more strongly on the outer peripheral surface of the tire (T).

When the non-slip belt (1) is mounted on the tire (T) as described above and the vehicle travels on a snowy road, an ice barn, or the like, the centrifugal force caused by the rotation of the tire causes the elastic restricting cord (8),
Even if (8) is slightly stretched, the tire main body (2) is not pressed by the outer peripheral surface of the tire from the beginning, so that the tire main body (2) does not generate tarlness, and thus no noise is generated.

Further, since the sheet-shaped non-slip pieces (4) are joined to the surface of the belt body (2) in a state of being adjacent to each other and have almost no irregularities on the contact surface of the anti-slip belt, smooth vibrations with almost no vibration are obtained. In addition to maintaining running, the anti-slip particles (11) on the anti-slip piece surface always suppress the tire slip as well as the braking slip.

When snow or ice adheres to the surface of the non-slip particles (11) of each of the non-slip pieces (4), the snow or ice adhered due to frictional heat generated when the anti-slip pieces (4) travel. Melts the ice and maintains the anti-slip action of the anti-slip particles (11).

Another embodiment of the first aspect of the present invention is shown in FIG.
As shown in the figure, a non-slip projection (6) is formed on the surface of a flexible sheet (60) such as nylon or polybutylene terephthalate.
1) A non-slip piece (54) formed by forming a large number of sheets joined to an elastic belt, and other structures are substantially the same as those shown in FIGS.

Another embodiment of the second aspect of the present invention is shown in FIG.
1, an inelastic belt (103) made of cotton cloth, synthetic leather or the like is used, and other structures are substantially the same as those shown in FIGS.

[0024]

According to the first aspect of the present invention, the belt body of the elastic belt is pressed against the outer peripheral surface of the tire and wound around without any thickening, and each knob piece is pulled to the center of the tire by the elastic drawing cord. By maintaining the state, the pressure contact winding around the outer peripheral surface of the tire of the belt main body is strengthened, thereby maintaining the elastic belt and the anti-slip material without the thickening when the tire rotates, and suppressing the generation of noise. You can.

According to the second aspect of the present invention, the sheet-shaped non-slip piece formed by completely bonding the non-slip particles to the belt surface is elastically bonded to the belt outer surface, so that the unevenness on the tire outer peripheral surface is the same as that of the conventional tire. Therefore, vibration during tire running can be eliminated, and side slip of the tire and slip during braking can be slightly stopped.
