Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tire slip band that can be fixed to a tire with one touch by operating a lever.

(Prior Art) When driving a car in a snowy area during the winter, on a snowy road or an icy road, a non-slip chain is attached to a tire, or spiked tires are attached to the vehicle to prevent slipping.

Many conventional metal anti-slip chains are of a ladder type, which is very troublesome to install and remove because it has a structure in which it is wound up along the outer circumference of the tire and connected after being jacked up.

In addition, there was a problem that the vehicle was noisy while running and running on a snow-free road resulted in abrasion and cutting in a short period of time.

Spike tires that have spike pins protruding instead of such metal chains are also becoming popular, but this is because the spike pins are always exposed, so noise is loud when driving on a snow-free asphalt pavement, and spike pins are also used. Shaving off asphalt, which caused dust pollution.

For this reason, studless tires without spike pins have been developed, but they were inferior to spiked tires in terms of braking performance and climbing power on a frozen road, and there was a problem of slipping especially on a steep slope.

In such a situation that a studless tire having sufficient safety has not been developed, a rubber anti-slip band has been developed instead of a metal chain, which is free from problems of dust and noise.

However, the work of attaching the rubber anti-slip band is poor in workability for fixing it by bolting,
The work was troublesome, especially when it was installed urgently on a cold road.

(Problems to be solved by the invention) The present invention eliminates the above-mentioned drawbacks and can be attached to the tire with one touch by lever operation, and there is no problem of dust or noise, and it can safely drive on snowy or frozen roads. The present invention provides a tire non-slip band that can be used.

(Means for Solving Problems) The present invention is directed to a tightening portion which is attached to the center of a wheel facing the outside of a vehicle body, and a plurality of radial portions which are attached from the tightening portion so that the outer peripheral surface of the tire is axially attached. A strip-shaped soft elastic plate that covers along with, a non-slip protrusion protruding from the tire ground contact surface of the soft elastic plate, and a portion of the tire elastic contact surface of the soft elastic plate and the tire side surface facing the inside of the vehicle body. J buried in one
A V-shaped metal rod, an engaging portion that is formed on the curved tip of the metal rod and that engages with the inner peripheral edge of the wheel that faces the inside of the vehicle body, and the metal that faces the outside of the vehicle body on the tire ground contact surface Wires that are respectively connected to the ends of the rod and are provided radially along the soft elastic plate, wire insertion holes that are radially formed in the tightening portion and through which the wires are inserted, and the central portion that bundles the wires. A cylinder that is connected to one end and is movably along the axial direction of the wheel, and a lever that is rotatably attached to the tightening part and a cylinder that is provided inside the tightening part and that has a tip connected to the cylinder. It is characterized by comprising a mechanism and a fixing portion which locks the lever mechanism in a state where the lever mechanism is rotated to move the cylinder toward the outside of the vehicle body to draw the wire.

(Operation) Next, the operation of the present invention will be described. A tire slip band is attached from the outside of the tire on a snowy road or a frozen road, and a soft elastic plate is spread to cover the outer circumference of the tire along the axial direction.

A J-shaped metal rod is integrally embedded in a portion that comes into contact with the ground contact surface of the soft elastic plate and the tire side surface facing the inside of the vehicle body, and a wire is connected to the end portion, so that the J
The V-shaped metal rod can be bent to cover the outer circumference of the tire.

After that, the engaging portion attached to the tip of the metal rod embedded in the soft elastic plate is engaged with the inner peripheral edge portion of the wheel located inside the vehicle body.

Next, when the lever is rotated, the wire connected to this end is pulled, and the engaging portion at the tip of the metal rod cannot be disengaged from the tire in a state of engaging with the inner peripheral edge portion of the wheel.

After that, when the lever is fixed, the wire remains in a pulled state, and the soft elastic plate provided with the anti-slip protrusion is closely fixed to the week surface of the tire.

Also, when you come to a road without snow, the operation is the reverse of the above.
When the lever is returned, the wire is loosened, and the tip end side of the soft elastic plate in which the metal rod is embedded freely rotates from the connecting portion with the wire, so that it can be easily removed from the tire.

(Embodiment) Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.

1 to 5 show an embodiment of the present invention, in which a tire slip band 1 is attached from one side of a tire 2 facing the outside of a vehicle body (not shown) as shown in FIG.

This tire anti-slip band 1 has five disc-shaped tightening portions 4 attached to the central portion of a wheel 3 and, on the outer periphery thereof, five strip-shaped soft elastic plates 5 are radially attached as shown in FIG. There is.

The soft elastic plate 5 is made of a soft material such as natural rubber or rigid rubber, is formed in a long band shape so as to cover the outer peripheral surface of the tire 2 along the axial direction, and as shown in FIG.
A plurality of non-slip projections 7 ...

Two J-shaped metal rods 8, 8 are arranged in parallel and integrally embedded in a portion of the soft elastic plate 5 that contacts the ground contact surface 6 and the side surface of the tire 2. Both ends of the metal rods 8 and 8 are exposed from the soft elastic plate 5, and the exposed both ends are connected by an arc-shaped connecting rod 9.

The connecting rod 9 provided on the side facing the inside of the vehicle body is an engaging portion 11 that engages with the annular recess 10 of the wheel 3 located inside the vehicle body, as shown in FIG.

As shown in FIG. 2, one end of a wire 12 is connected to a connecting rod 9 provided outside the vehicle body on the grounding surface 6, and each wire is connected to the connecting rod 9.
The other ends of 12 ... Are radially attached from the tightening portion 4.

As shown in FIG. 4, the tightening portion 4 has a wire insertion hole 13 radially formed therein, and the wires 12 inserted into the wire insertion hole 13 are bundled at a central portion to move laterally. It is connected to the left end of 14.

A slit 15 is formed at the right end of the cylinder 14, and a plate-like portion 17 of a lever 16 is fitted therein, and is rotatably connected to a long hole 18 formed therein by a pin 19.

A groove portion 20 is formed on the side surface of the tightening portion 4, and the lever 16 is rotatably attached thereto by a pin 21.

Further, a slit 23 is formed at an end of the columnar portion 22 of the lever 16 so as to be orthogonal to the plate-shaped portion 17, and the grip portion 24 has a pin 25.
It is rotatably connected with.

Also, at the lower end of the groove portion 20, a fixing portion 26 having an inverted U-shape in the lateral direction is formed.

Next, the method of use will be described. When the tire anti-slip band 1 is inserted and attached on a snowy road or a frozen road where there is a risk of slipping, first, as shown by the phantom line in FIG. Spread the plate 5 and cover it as shown by the solid line.

At this time, since the J-shaped metal rods 8 are integrally embedded in a portion of the soft elastic plate 5 that contacts the ground contact surface 6 and the side surface of the tire 2, the metal rod 8 is exposed although it does not bend at this portion. Since the connecting portion between the connecting rod 9 and the wire 12 at the end is flexible, it can be bent from here and easily covered on the outer periphery of the tire 2.

When the soft elastic plate 5 is covered on the outer circumference of the tire 2, the engaging portion 11 at the tip of the metal rod 8 is engaged with the annular recess 10 of the wheel 3 located inside the vehicle body as shown in FIG. After this, the fourth
When the grip portion 24 is gripped by the hand and pushed down in the direction of the arrow from the state shown in the drawing, the lever 16 also rotates integrally with the pin 21 as the rotation center.

When the lever 16 rotates, the cylinder 14 connected by the pin 19 inserted in the elongated hole 18 moves to the right side in the figure as shown in FIG. 5, and the wire 12 connected to this end is pulled.

As a result, the wire 12 is strongly pulled in a state where the engaging portion 11 at the tip of the metal rod 8 is engaged with the annular recess 10 of the wheel 3, so that the metal rod 8 does not come off from the tire 2 in a bite state.

After that, as shown in FIG. 2, the grip portion 24 is rotated in the direction of the arrow so that the intermediate plate-shaped portion of the grip portion 24 becomes the inverted U-shaped fixing portion 26 formed laterally at the lower end of the groove portion 20. When fitted, the lever 16 is vertically fixed in the groove 20 and the cylinder 14 connected thereto is also not moved, so that the wire 12 is pulled and the soft elastic plate 5 is brought into close contact with the peripheral surface of the tire 2. And then fixed.

Therefore, when pulling the wire 12, the lever 16 and the grip
Since 24 becomes long as a unit, a large force can be obtained, and when fixing, the gripping part 24 is bent laterally and stored in the tightening part 4 so that it does not project outside while traveling. There is.

When the vehicle is run in this state, the ground contact surface 6 of the soft elastic plate 5
The non-slip protrusions 7 protruding from the digging into the road surface,
Since there is a step between the surface of the tire 2 and the soft elastic plate 5, slipping can be prevented.

Also, when you come to a road without snow, the operation is the reverse of the above.
When the grip portion 24 is grasped by hand and rotated in the circumferential direction of the tire 2 and becomes linear with the lever 16, when the grip portion 24 is pulled up in the direction opposite to the arrow shown in FIG. 4, the cylinder 14 is returned. Wire 12 loosens.

In this state, the tip end side of the soft elastic plate 5 in which the metal rod 8 is embedded as shown in FIG. 1 freely rotates from the connecting portion with the wire 12 as shown by the phantom line, so that the tire 2 can be easily moved. It can be removed.

In the above embodiment, the case where five soft elastic plates 5 are radially attached from the tightening portion 4 has been described, but this number can be arbitrarily selected.

Further, the fixing mechanism of the lever 16 is not limited to the above-mentioned embodiment, but may have another structure.

(Effects of the Invention) As described above, according to the tire anti-slip band of the present invention, it can be attached to the tire with one touch by operating the lever, and it is extremely excellent in workability and has no problem of dust or noise. It is possible to drive safely on snowy or frozen roads.
