Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an anti-slip device made of synthetic resin that is attached to a tire to prevent a car from slipping when driving on a snowy road surface, and particularly relates to a non-slip device made of synthetic resin that is attached to a tire of a car to prevent it from slipping when driving on a snowy road surface. This relates to an anti-slip device used for.

[Prior Art] Conventionally, tire chains have been used as anti-skid devices for tires, such as tire chains connected in the form of a ladder, but this is undesirable because it causes intermittent shocks while the vehicle is running, and is particularly difficult to drive on dry roads. The drawback was that the impact was so great that it was difficult to drive. For this reason, synthetic resin tire anti-slip devices have been developed in recent years, in which a tire anti-slip band made of synthetic resin is used by covering the outer periphery of the tire.

[Problems to be solved by the invention] This type of synthetic resin tire anti-slip device for double tires is also being researched, but in anti-slip devices for double tires, the width of the tire anti-slip piece is Because it inevitably becomes wider,
There was a problem in that the center part became unstable, and the center of the non-slip piece was moved greatly between the road surface and the tire during driving and was subjected to large tension, resulting in deterioration of the durability of the non-slip piece.

``Means for Solving the Problems'' The present invention has been made in view of the above points, and when installed on a double tire, the anti-slip piece is securely placed around the tire so that it hardly moves. The purpose of the present invention is to provide an anti-slip device for a tire that can be set and improve the durability of anti-slip pieces, and is configured as follows. 1
As shown in the figure, there is a flexible tire non-slip piece 3 made of synthetic resin that can be attached along an arcuate surface at an arbitrary angle around the outer circumference of the tire 1, and the tire anti-slip piece 3 corresponds to the outer circumference of the tire 1. A first connector 4 for connecting a plurality of tire anti-slip pieces 3 in a band shape, and a locking and disengaging device for connecting both ends of a tire anti-slip band 5, which is a plurality of tire anti-skid pieces 3 connected together, to form an endless tire anti-slip band. A possible second connector 6 and a plurality of tire anti-slip pieces 3 connected in an endless manner to cover the outer periphery of the tire are pulled toward the center of the tire 1 by pulling the tire front sides of the tire anti-slip pieces 3 to the tire. 1. In a tire anti-slip device equipped with a fastening tool 8 for tightly fitting the tire anti-slip piece 3 to the outer periphery, a central connecting strip 30 is provided continuously on the back side in the central longitudinal direction of the tire anti-skid piece 3, and the central connecting strip 30 Holes 3 at both ends of the strip
2 and projecting on the back side, and when the tire anti-skid pieces 3 are connected as an endless tire non-slip band, the central connecting strip 30 is provided with an ear part 31 that connects the ears 31 of adjacent central connecting strips 30 to each other. It is configured by providing a connector 33.

[Function] As illustrated in FIG. 1, in the tire anti-slip device of the present invention, the flexible tire anti-slip piece 3 molded from synthetic resin is formed wide for a double tire and covers the outer circumference of the tire. It is installed in the transverse direction. As illustrated in FIG. 2, a hole 16.17 is provided at the end of the tire anti-slip piece 3, and the first connector 4 is inserted into the hole 16.17 to prevent the tire from slipping. A plurality of pieces 3 are connected in a band shape along the outer circumference of the tire. Further, the second connector 6 connects both ends of the tire non-slip band 5 (FIG. 1), which is formed by connecting a plurality of the tire non-slip pieces 3, to form an endless tire non-slip band. As a result, tire 1
The endless tire stop band attached to the tire prevents the tire 1 from slipping when the tire 1 rotates. Next, the tightening tool 8 pulls the tire front sides of the anti-slip pieces 3 of the plurality of tires 1 connected in an endless manner to cover the outer periphery of the tire 1 toward the center of the tire 1 to slip the tire. The stopper piece 3 is brought into close contact with the outer circumference of the tire. Thereby, the fastener 8 prevents the endless tire anti-slip band from moving when the tire 1 rotates. The central connecting portion 30 is connected to the back side of the tire anti-slip piece 3 in the central longitudinal direction, and is connected to the central connecting strip portion 3.
There are holes 32 at both ends of the tire 0, and protruding ears 31 on the back side of the tire anti-slip piece 3. The central connector 33 connects the ears 31 of the adjacent central connecting strips 30 to each other when the tire anti-slip pieces 3 are connected as an endless tire anti-slip band. This causes the central connector 33 to fit inside the double tire and the holes 15, 16, 17.
To reduce the contact of the ear part 31 with the road surface or tires.

As described above, in the present invention, the technical problems of the present invention are solved by the operation of each component.

[Example] Next, one embodiment of the present invention will be described based on the drawings.

FIG. 2 shows a plan view of a flexible tire anti-slip piece 3 made of synthetic resin such as polyurethane.

This tire anti-skid piece 3 is formed wide for double tires, and has four band-shaped anti-slip parts 11 mounted at equal intervals in a direction that crosses the outer circumference of the tire, that is, in the width (thickness) direction of the tire. They are integrally molded so as to be connected by a W-shaped connecting piece 12. Further, a central connecting strip 30 is provided continuously on the rear side in the central longitudinal direction of the tire anti-skid piece 3, that is, in the transverse direction center of the band-like anti-skid portion 11, and the central connecting strip 30 is provided as shown in FIG. Ears 31 are provided at both ends to protrude to the back side, and a hole 32 for hooking a central connector 33, which will be described later, is bored in the ears 31. On the outer side of the tire anti-slip piece 3 when installed, that is, the lower end in FIG. At the upper end in FIG. 2, a bar-shaped shorting piece 14 is provided at the left end with the right side facing.

A hole 15 for passing the first connector 4 (described later) is provided in the center of the substantially disc-shaped both ends of the hooking part 13, and similar holes 16 and 17 are provided in the base and tip of the short-circuiting piece 14. provided. The upper part of the connecting piece 12 that connects the upper part of each band-like non-slip part 11 and the tip of the shorting piece 14 have a slit-shaped length into which a fixing fitting 18 is inserted in order to fix the shorting piece 14 to the connecting piece 12. A hole 19 is drilled. And the fixing fitting 18 (Fig. 5)
is fitted into the elongated hole 19 at the tip of the short-circuiting piece 14 and the elongated hole 19 at the tip of the right-end connecting piece 12, and is swaged as shown in FIG. 5, so that the shorting piece 14 is fixed to the connecting piece 12.

As can be seen in FIG. 2, since the shorting piece 14 is shorter than the connecting piece 12, when the right end of the shorting piece 14 is fixed, the tire antiskid piece 3 will be bent so as to wrap around a part of the inside of the tire 1. Furthermore, metal fittings (not shown) are fitted into the elongated holes 19 of the connecting piece 12 in the intermediate portion, and the shorting piece 14 and the connecting piece 12 are fixed at four locations by these metal fittings.

Note that a plurality of studs 20 are driven onto the four band-shaped non-slip portions 11 to prevent slipping.

For example, four of the tire anti-skid pieces 3 configured in this manner are connected in a band shape to form a tire anti-skid band 5, which is then attached to the double tire 1.

That is, first, the four tire anti-slip pieces 3 are arranged so as to be connected laterally, and as shown in FIG.
are connected by a first connector 4 made of a C-shaped metal fitting, and similarly, the adjacent end of the shorting piece 14 is also connected to the first connector 4.
They are connected by fitting them through the holes 17.

The tire stop strip 5 formed in this way is a double tire 1.
The hanging parts 13 at both open ends are removably connected by passing the second connector 6 through the hole 15, and similarly, the ends of the shorting piece 14 are connected to each other by passing the second connector 6 through the hole 16. ．．
By passing the second connector 6 through 17, they are removably connected. In this state, the central connecting strip 30 and the ears 31 arranged on the back side of the center of the tire anti-skid belt 5 enter between the double tire 1, and roughly the both ears 31 of the adjacent central connecting strip 30 A central connector 33 in the form of a hook fitting is passed through the hole 32, and this is removably connected.

Then, as shown in FIG. The attachment 8 is hooked along the hook 13. The tire stopper belt 5 is pulled to the outside of the double tire 1 by the tightening part 8, and the tire stopper belt 5 is reliably attached to the outer circumference of the tire without loosening.

While the vehicle is running, due to the transfer of the double tires 1, each band-shaped anti-slip piece 11 of the tire anti-slip band 5 absorbs the rotational force of the tire.
Although it is subjected to large frictional resistance with the road surface and is pulled or twisted, since the center of all the band-shaped non-slip parts 11 is firmly connected in the circumferential direction by the central connecting strip 30, each Since the band-shaped non-slip portion 11 is held at the bifurcated point of its entire width, it can be lifted up when the double tire 1 rotates. In addition, since the central connector 33 and ears 31 that connect the central connecting strips 30 of each tire anti-slip piece 3 fit between the double tire 1, that is, the two tires, they rarely touch the road surface and The connected state can be stably maintained.

If the diameters of the tires are different, the tire anti-slip pieces 3 may be connected using different sizes and lengths of the first connector 4, second connector 6, and central connector 33. Accordingly, the length of the tire stopper belt 5 can be adjusted to some extent to match the tire diameter.

Further, when the tires have different thicknesses and widths, the tire non-slip belt 5 can be installed without loosening by using the elastic fastener 8 or by changing the length of the hook fitting 21 for hooking it.

In addition, in the above embodiment, a tire non-slip piece having a band-like non-slip part was used, but any tire non-slip piece having a non-slip part divided into a plurality of parts via a connecting piece can be used according to the present invention. It is possible to apply

[Effects of the Invention] As explained above, according to the tire anti-skid device of the present invention, a central connecting strip is provided continuously on the rear side in the central longitudinal direction of the tire anti-skid piece, and the ear portions at both ends are connected to each other. It is configured to be interconnected with that of the tire anti-slip piece by a central connector. Therefore, when a tire non-skid band in which such tire non-skid pieces are connected is attached to a double tire, the center of the tire non-skid piece will not become unstable, and the durability of the tire non-skid piece can be improved. can. In addition, because the central connecting strip and the central connecting tool that connects it fit between the double tires,
This hardly touches the road surface or the tires, and it is possible to prevent the central connector from coming off.
