Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a tire anti-slip device.

(Prior Art) Recently, non-metallic anti-skid devices have been attracting attention in place of metal chains as anti-slip devices for automobile tires.

In the non-metallic anti-skid tool, as shown in FIG. 7, a band-shaped wrapping body 26 is wrapped around the outer peripheral surface of a tire 27, and connecting portions 2 at both longitudinal ends of the wrapping body 26 are connected to each other.
8 in the width direction are releasably connected to each other by a connecting tool 29, and the connecting portion 28 of the wound body 26
The engagement tool 3 is connected to the annular tightening rope 30 disposed on each left and right side of the tire 27.
1 and 32.

(Problems to be Solved by the Invention) By the way, in the above-mentioned conventional non-slip device, when the non-slip device is attached to and removed from the multi-ear 27, the wrapping body 2
6, connecting each end of the connecting portions 28 in the width direction with each other;
When the above-mentioned respective ends are engaged with the tightening rope 30, they are carried out completely separately using separate coupling tools 29 and engagement parts 31, and therefore the above-mentioned connection/release work and engagement are performed separately. There was a problem in that the removal work was troublesome and the work of attaching and detaching the anti-slip device to the tire 27 could not be easily performed.

The object of the present invention is to provide a tire skid device that can solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized in that the band-shaped wrapping body 8 is wound around the outer peripheral surface of the tire 1, and the band-shaped wrapping body 8 is wound in the longitudinal direction Connecting parts 1 at both ends
4 comrades are releasably connected, and each widthwise end edge of the wrapped body 8 is engaged with annular tightening cables 10 disposed on each left and right side of the tire 1, in which both connecting portions The ends of the wound body 14 in the width direction are releasably connected to each other by a pair of connectors 11, and each connector 11 is attached to one of the connectors 14 so as to rotate about its axis in the thickness direction. A first hook 1 that is freely provided and is removably engaged with each tightening rope 10.
8, and a second hook 19 which is rotatably provided on the other connecting portion 14 about its axis in the thickness direction and is removably engaged with the first hook 18.

(Function) When installing the tire skid device 7 on the tire 1,
The anti-slip device 7 is wound around the tire 1, and the second hook 19 is engaged with the first hook 18 of each connecting device 11 to connect both connecting portions 14 of the wrapped body 8, and the first hook 18 is connected. It engages the tightening rope 10.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings of FIGS. 1 to 6. In FIGS. 2 and 3, 1 is a tire, 2 is a tread part, and 3 is a shoulder part. , 4 is a side wall portion, 5 is a rim, and 6 is a disk.

As shown in Fig. 1, 7 is a tire anti-slip device;
It has a band-shaped winding body 8, a large number of engagement tools 9, a pair of left and right tightening ropes 10, a pair of left and right connectors 11, and the like.

The wrapping body 8 is detachably wrapped around the outer circumferential surface of the tire 1 over the tread portion 2, shoulder portion 3, and sidewall portion 4. By covering it, it is formed into a mesh shape. A pair of connecting portions 14 that are elongated in the width direction are provided at both ends of the wound body 8 in the longitudinal direction. 15 is a spike.

One end of the engaging portion 9 is fixed to the outer side of each mesh on each side of the wound body 8 in the width direction, respectively, in a non-removable or detachable manner. The other end is a tension cable 10 arranged on each side of the tire 1.
It is engaged in a detachable or non-releasable manner.

The tightening cable 10 has a ring shape, and both ends thereof are releasably connected by a connector 17.

The connector 11 connects the ends of both connectors 14 in the width direction and is removably engaged with the tightening rope 10, as shown in FIGS. 4 to 6. It has a first hook 18 and a second hook 19. The first hook 18 is shaped like a letter when viewed from the front, and a bolt 20 fixed to the base thereof is inserted into one end of the connecting portion 14 in the width direction of the wound body. The first hook 18 is provided in the connecting portion 14 in a rotatable and detachable manner by screwing the nut 21 into the connecting portion 14 . A hook portion 22 that is U-shaped in side view is formed at the tip of the first hook 18 and is removably engaged with the tightening rope 10 .
A bolt 23 is also fixed to the base end of the second hook 19, and the bolt 23 is connected to the other connecting portion 14.
The second hook 19 is inserted into one end of the wound body in the width direction, and a nut 24 is screwed onto the bolt 23, so that the second hook 19 is rotatably and detachably provided on the connecting portion 14. At the tip of the second hook 19,
A hook portion 34 having a U-shape in side view is formed to be removably engaged with the engagement hole 25 in the middle of the first hook 18 .

According to the embodiment configured as described above, when installing the tire skid device 7 on the tire 1, the engagement between the first hook 18 and the second hook 19 of each connector 11 is released, Both the connecting parts 14 of the wrapped body 8 are disconnected, and the tightening rope 10 of the first hook 18 is
Also release the engagement. In addition, the connection of the tightening rope 10 by the connecting tool 17 is also released, and the engaging tool 9 on the left side of the connecting tool 17 in FIG.
The engagement with the tension rope 10 is also released, and the slipper 7
Make it into a strip.

Then, the band-shaped anti-slip device 7 is wrapped around the outer peripheral surface of the tire 1, and the second hook is attached to the first hook 18 of each connector 11.
By engaging the hook 19, both connecting portions 14 of the wrapped body 8 are connected.
At the same time, the first hook 18 and the disengaged engagement tool 9 are engaged with the tension rope 10, and in this state, if they are connected by the tension rope 10, the first hook 18 and the second hook are connected. 19 is each bolt 20, 23
While rotating around the axis, the distance between the two connecting portions 14 is easily and smoothly reduced, and the work of attaching the anti-slip device 7 to the tire 1 is completed.

The removal of the anti-skid tool 7 from the tire 1 may be performed in the reverse order to the above.

(Effects of the invention) As detailed above, according to the invention, the ends of the wound body in the width direction of both connecting parts are releasably connected to each other by a pair of connecting tools, and each connecting tool is , a first hook is provided on one connecting portion so as to be rotatable around an axis in the thickness direction thereof and is removably engaged with each of the tightening ropes; Since it has a second hook that is rotatably provided around the center and is detachably engaged with the first hook, it is possible to connect the ends of the wound body in the width direction of the two connecting portions to each other, as in the conventional case. The connection and engagement of each end with the tightening rope were performed completely separately using separate connectors and engagement tools.
To easily perform release and engagement operations, to easily attach and detach the skid stopper to and from a tire, and to easily and smoothly reduce the distance between both connecting parts when the skid stopper is attached to the tire. The present invention has the above advantages,
It is very profitable.
