Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire non-slip device mounted on a tire when a vehicle runs on a snowy road or the like to prevent slipping.

[0002]

2. Description of the Related Art In a tire anti-skid device, it is required that the work of attaching to and detaching from the tire be facilitated. For example, a plurality of anti-slip members to be mounted over the tread surface of the tire are provided between a pair of left and right side bands. By connecting at equal intervals, the anti-slip member near the joint end of the side band is given elasticity that can be crimped to both sides of the tire, and when attached, the anti-slip member near the joint end of the side band is attached to the tire. After temporarily fixing to the tire, the vehicle is moved and other anti-slip members are sequentially wound around the tire to be mounted (eg, JP-A-2-
No. 120102), a plurality of anti-slip members having lateral arm portions are provided radially slidably on an annular base body attached to the side surface of the wheel, and each anti-slip member is always attached in the center direction by expansion deformation of the air bag. The annular base body is attached to the side surface of the wheel so that the lateral arm portion of the anti-slip member is located on the tread surface of the tire when it is mounted (eg, the actual open flat number 3-38202). (See the official gazette) and the like have been proposed.

[0003]

However, in the former tire anti-skid device, when the anti-skid device is attached, the anti-slip member near the coupling end of the side band is temporarily attached to the tire, and then the vehicle is moved to prevent the other anti-slip devices. Since the members are sequentially mounted, the respective anti-slip members may not be properly engaged, and it is necessary to accurately arrange the anti-slip members. Also, after engaging the respective anti-slip members, the connecting ends of the side bands are connected, and one end of the outer side band of the tire is pulled to remove the looseness, but this work requires a large force, and It may not be possible to evenly tighten each of the anti-slip members, and it is necessary to re-tighten after running for a while.

On the other hand, in the latter tire anti-skid device, since each anti-slip member and the annular base body are integrated and are large and heavy, a large force is required at the time of attachment / detachment and at the time of storage. It requires a large storage space similar to tires. Since each anti-slip member is slidably provided on the annular base member and is constantly urged toward the center by the air bag, the structure is complicated.

The present invention has been made in view of the above conventional situation, and an object thereof is to provide a tire anti-slip device having a lightweight and simple structure, which can be easily attached and detached.

[0006]

In order to solve the above-mentioned problems, a tire anti-skid device of the present invention comprises a plurality of anti-skid bodies mounted on the side surface of a wheel at predetermined intervals so as to be mounted and dismounted on the tread surface of the tire. It is designed to be connected and fixed as much as possible. Each of the anti-slip bodies is a non-slip body that is mounted across the toled surface of the tire, an inward coupling means that is provided at one end of the anti-slip body and that engages with the inner side surface of the wheel, and the anti-slip body. A fastener provided at the other end of the wheel and having an outer connecting means for engaging the outer side surface of the wheel, wherein the inner connecting means of each anti-skid body is engaged with the inner side surface of the wheel. Inner locking means are provided at equal intervals, and outer locking means for engaging the outer coupling means of the tightening tool of each anti-slip body are provided on the outer side surface in correspondence with the inner locking means. ing.

When mounted on a tire, the inward coupling means of the anti-slip body is engaged with the inward locking means of the wheel, the anti-slip body is placed across the tire's tread surface, and the tightening device is released. .. Then, the outer connecting means of the tightening tool is engaged with the outer locking means of the wheel, and the tightening operation of the tightening tool is performed. As a result, the anti-slip body has the anti-slip body pressure-bonded to the tire's tread surface, and both ends are connected and fixed to the side surface of the wheel.
It will be attached to the tire. After that, the other non-slip bodies are sequentially mounted in the same manner.

When the tire is disengaged from the tire, the tightening tool is released to release the engagement between the outer connecting means and the outer locking means, and the antiskid body is moved inward to move the inner connecting means and the inner connecting means. The engagement with the locking means is released, and the anti-slip body is removed from the tire.

Embodiments of the present invention will be described with reference to the drawings. The tire anti-skid device 1 shown in the figure comprises eight anti-skid bodies 2, both ends of which are removably connected and fixed to a wheel 3 and mounted at equal intervals along the outer circumference of the tire 4. It is about to do.

The non-slip body 2 is a plate-like body made of a material such as rubber or resin, and has a non-slip body 5 formed in a downward C shape as shown in an enlarged view in FIG. An inner ring-shaped connecting body 6 is provided at one end of 5, and a tightening tool 7 is provided at the other end. The inner ring-shaped connecting body 6 engages with an inner locking projection 8 of a wheel, which will be described later, and is rotatably attached to one end of the anti-slip body 5 so as to be able to maintain a predetermined posture. ing. The tightening tool 7 is
An actuating lever 7c is pivotally attached to a base plate 7a fixed to the non-slip body 5 with a tack or the like via a pivot shaft 7b, and an outer annular shape is provided in the middle of the actuating lever 7c to engage with an outer engaging projection 9 of a wheel described later. The connecting body 7d is rotatably provided, and by rotating the operating lever 7c to open and close the outer ring-shaped connecting body 7d.
It is designed to move up and down. As for the distance between the inner annular connecting body 6 and the outer annular connecting body 7d, the inner annular connecting body 6 is engaged with the inner locking protrusion 8 and the outer annular connecting body 7d is engaged with the outer locking protrusion 9. When the operating lever 7c is closed after the engagement, the anti-slip body 5 is set so as to come into close contact with the tread surface 4a and both side surfaces 4b of the tire. The operating lever 7c
Is always elastically biased toward the base body 7a by a spring or the like to be in a closed state.

The wheel 3 has a rim 3 as shown in FIG.
Inner locking projections 8 for engaging the inner annular connecting body 6 with the inner end surface 3b of a are provided at eight positions at equal intervals, and the outer annular connecting body 7d of the tightening tool is provided on the outer end surface 3c of the rim 3a. An outer locking projection 9 for engaging with is provided corresponding to the inner locking projection 8. It should be noted that the locking protrusions 8 and 9 are provided on the disk 3 of the wheel.

The tire anti-skid device shown in FIGS. 1 to 3 is constructed as described above, and when mounted on the tire 4, the inner annular connecting body 6 of the anti-slip body is engaged with the inward locking projection 8 of the wheel.
And the non-slip body 5 is arranged so as to straddle the tread surface 4a of the tire. And the operating lever 7 of the tightening tool
c is opened, the outer annular coupling body 7d is engaged with the outer locking projection 9 of the wheel, and the operating lever 7c is closed. Operating lever 7c
The outer ring-shaped connecting body 7d is pulled up by closing, but after the outer ring-shaped connecting body 7d abuts on the outer locking projection 9, the anti-slip body 5 is pulled toward the outer locking projection 9 side. At that time, since the other end side of the non-slip body 5 is connected and fixed to the inner locking projection 8 through the inner annular connecting body 6,
The anti-slip body 5 is strained on both ends. As a result, the non-slip body 2 has the anti-slip body 5 on the tire's tread surface 4
It is attached to a and the both side surfaces 4b by pressure bonding so as to be in close contact. After that, the other anti-skid bodies 2 are sequentially mounted in the same manner, but the vehicle is slightly moved and mounted in the same manner as above at the portion where the tread surface 4a of the tire is in contact with the ground.

When detaching from the tire 4, the operation is carried out in the reverse order of the mounting, but the outer annular connecting body 7d and the outer locking projection 9 are engaged by opening the operating lever 7c of the tightening tool. It is released, and the tension of the anti-slip body 5 is released. Then, the other end side of the anti-slip body 5 is moved obliquely downward by lifting the tightening tool 7 side of the anti-slip body 5, and the engagement between the inner annular coupling body 6 and the inner locking projection 8 is released. .. As a result, the anti-skid body 2 is removed from the tire 4.

According to the tire anti-skid device 1 shown in FIGS. 1 to 3, since the respective sliding upper bodies 2 are independent of each other, they can be individually attached and detached, and the respective annular coupling bodies 6 and 7d and the respective locking bodies are engaged. Since the projections 8 and 9 can be easily and reliably engaged or disengaged, the work for attaching and detaching each anti-slip body 2 can be performed smoothly and quickly.

The present invention is not limited to what is shown in FIGS. 1 to 3, and for example, the anti-slip body 2 is shown in FIG.
It may be configured as shown in. The anti-skid body 2 shown in FIG. 4 is the same as that shown in FIGS. 1 to 3 except for the configuration of the tightening tool 7, so only the tightening tool 7 will be described. In the tightening tool 7 shown in the figure, the outer annular connecting body 7d has the L portion support plate 10a
A pair of support members 10 formed by connecting a lower support plate 10b and a lower support plate 10b by attaching compression springs (not shown) between the spring seats 10c and 10d, and a connecting rod 11 attached to the lower end of each support member 10. And the upper end of each support member 10 is rotatably provided in the middle of the operating lever 7c. This allows
When the anti-slip body 2 is mounted on the tire, each support member 10 expands and contracts, so that the anti-slip body 2 can be naturally connected and fixed to the outer locking projection 9 of the wheel.

The shape of the non-slip body 5 may be any of flat plate, net, chain, and the like, and it is preferable that each has flexibility. The anti-skid body 2 has a wide anti-slip body 5, for example, an inner annular connecting body 6 when the anti-slip body 5 is attached to four positions of the tire 4.
It is preferable that the tightening tool 7 is provided at both ends or a plurality of positions in the rotation direction of the tire 4. At that time, the inner locking projections 8 and the outer locking projections 9 of the wheel 3 are provided at the mounting positions of the anti-skid bodies 2 corresponding to the numbers of the inner annular coupling bodies 6 and the tightening tools 7. The respective annular connecting bodies and the respective locking protrusions may have arcuate portions in contact with each other. It is preferable that each annular connecting body is provided with a step at the abutting portion so as not to move relative to each locking projection in the tire rotation direction. It can be mounted respectively on double tires that are arranged close to each other on the same axle, but for inner tires, the locking projection facing the outer tire side is the inner locking projection, Mount the non-slip body from the vehicle body side.

[0017]

According to the present invention, the anti-slip body is small and lightweight because the width of the anti-slip body is such that the width of the anti-slip body extends over a part of the tread surface of the tire, and it is compact even if a plurality of them are combined. Can be stored. The anti-slip body is independent of each other, and each end of the anti-slip body is attached to the tire by connecting and fixing each end of the anti-slip body to the wheel through the inner connecting body and the tightening tool. Since it does not require a large amount of force, it is possible to securely and easily attach and detach the tire.

The non-slip body has both ends of the non-slip body connected to and fixed to the wheel, and moreover, is attached to the tire's tread surface in a close contact state.
It does not fall off easily and can reliably exhibit the function as an anti-slip device.
