Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention is applicable to a tire slip prevention device, particularly a device of this type formed of rubber, urethane elastomer, etc. into a ladder shape or a net shape. This invention relates to a method of attaching a locking device.

[Prior Art] FIG. 14 shows a tire anti-slip device 10 made of rubber molded into a net shape. In this arrangement, a plurality of hooks 14 and 16 are attached to both ends of the main body member 12 in the width direction along the longitudinal direction. An inner tightening member 18 made of a resin rope or wire rope with a relatively small elongation rate is attached to each hook 14. The inner tightening member 18 has a main body member inner joint hook 20 attached to one end and an inner tightening member joint hook 22 attached to the other end.

The main body member 12 is placed over the tire with the side to which the hook 14 is attached placed on the inside of the tire. The inner tightening member 18 has a main body member inner joint hook 20 hooked to an inner joint hole 24 formed in the main body member 12.
The ends of the inner fastening member are hooked together by a joint hook 22.

An outer tightening member 26 made of an elastic annular body such as a rubber ring shown in FIG. 15 is hung around each hook 16. A main body member outer joint hook 28 having a bifurcated hook portion is attached to the outer tightening member 26 . Each hook part of this joint hook 28 is
They are respectively hooked into two outer joint holes 30 formed in the main body member 12.

As a result, the tire slip prevention device 10 has the main body member 12
are connected in a cylindrical shape, tightened by an inner tightening member 18 and an outer tightening member 26, and mounted on a tire 32 as shown in FIG.

By the way, in the above-mentioned tire slip prevention device gllO, especially when the vehicle is running, the main body member 12 is not in complete contact with the tire 32 and there is a circumferential difference between the two. relative movement is made around the tire 32 at a very slow speed (about 1/1000 of the tire rotational speed) in the opposite direction (arrow A direction) and the opposite direction (arrow B direction).

Therefore, as shown by arrow C in FIG. 14, the main body member 12 has a problem in that the shoulder portion 12A and the joint portion 12B are twisted, causing uneven wear and shortening the service life.

In addition, since the back surface of the main body member 12 and the surface of the tire 32 rub against each other and become sticky, it becomes difficult to remove the tire slip prevention device lO smoothly, and the lifespan is shortened due to wear. There is a problem with that.

Furthermore, there is a problem in that the main body member 12 tends to shift from the tire 32 in the width direction or come off and get caught on the axle side due to rapid spinning of the tire 32 or rapid braking/turning operation of the vehicle.

The above-mentioned problems are caused by snow tires in which the pattern grooves in the shoulder portion are deep and the main body member 12 is easily twisted at the turning portion, and spike tires in which the main body member 12 is easily damaged by the bottle in the tread portion due to protruding bottles. If you do, it will become more noticeable.

[Problems to be Solved by the Invention] In view of the above, the present invention provides a method for installing a tire anti-slip device that can solve the above problems by eliminating relative movement between the tire and the tire anti-slip device while the vehicle is running. is intended to provide.

[Means for Solving the Problems] In the method for installing a tire anti-slip device according to the present invention, the tire anti-slip device is connected to a wheel via a tensile strength member.

[Function] In the present invention configured as described above, the tire anti-slip device is restrained to the wheel by the tensile strength member, and movement relative to the tire is prevented.

[Example] In the following examples, the same reference numerals are given to the same components as those described above, and the explanation thereof is omitted.

FIGS. 1 and 2 show a first embodiment of the method for attaching a tire slip prevention device according to the present invention, and FIG. 3 shows a connecting tool used in this embodiment. .

As shown in FIG. 1, the tire anti-slip device 10 has a main body member 12 connected in a cylindrical shape, which is tightened by an inner tightening member 18 and an outer tightening member 26, and is attached to a tire 32. Same as above. However, in this embodiment, the pattern shape of the main body member 12 is different from that described above, and is a combination of a substantially rhombic frame shape as a basic pattern and a substantially triangular frame shape.

As shown in FIG. 3, the connector 34 is constructed by attaching metal hooks 38 to both ends of a tensile strength member 36 (hereinafter referred to as lobes 36) such as a wire rope or fiber lobe.

The connector 34 is installed after the main body member 12 is attached to the tire 32 with the inner tightening member 18 and the outer tightening member 26. One hook 38 of the connector 34 connects to the wheel 4
It is inserted through a decorative hole 44, mainly for ventilation, which is bored in the disc part 42 of the wheel 40, and then turned to the back side of the wheel 40, and as shown in FIG. It is hooked to a main body member inner joint hook 20 attached to the attaching member 18.

The other hook 38 then connects to the second hook on the front side of the wheel 40.
As shown in Figure (A), it is hooked to the main body member outer joint hook 28.

As a result, the rope 36 is folded back at the decorative hole 44 and the folded portion of the rope 36 is locked to the wheel 40, thereby connecting the tire anti-slip device filO to the wheel 40 via the connector 34.

Although a plurality of S holes 44 are provided in the same pitch field, those located on the rotational direction (direction of arrow A) side of the tire 32 with respect to the engaging portion of the hook 38 are selected.

Next, 1l of tire non-slip installed as above
The action of Hto will be explained.

When the connector 34 is in a state immediately after the tire slip prevention device filO is attached to the tire 32 and before the vehicle is running, the rope 36 is slightly slack. This is because the rope 36 has tensile strength and is not substantially bonyly deformed in the longitudinal direction, so it is difficult to wear it in a tensioned state from the viewpoint of ease of wearing.

Therefore, the main body member 12 is rotated in the opposite direction to the rotation direction of the tire 32 until the rope 36 is loosened. However, this state lasts only a short time. Therefore, soon after the vehicle starts running, the rope 36 becomes loose, and the inner tightening member 18 and the outer tightening member 2
is pulled by the rope 36 and the tension becomes large.

As a result, the main body member 12 is tightly attached to the tire 32, and the difference in circumferential length between the tire 32 and the tire 32 is small, making it difficult for relative movement to occur with respect to the tire 32, and even if a relative movement attempts to occur, it is restrained by the rope 36. Therefore, relative movement with the tire 32 is reliably prevented. Therefore, the aforementioned problems caused by relative motion do not occur.

Moreover, when releasing the attachment of the connector 34, the tension on the rope 36 which is in a tensioned state can be released by removing the outer tightening member 26 from the hook 16, so that the attachment can be easily released.

FIG. 4 shows the main parts of a second embodiment of the present invention, and FIG. 5 shows a connector used in this embodiment. This embodiment differs from the first embodiment only in a part of the connector.

As shown in FIG. 5, the connector 34A of this embodiment is different from the connector 34 of the first embodiment in that a buckle 46 is attached to one end of the rope 36 instead of a hook 38. This is what is happening. This buckle 46 has a toggle mechanism and can be opened in the direction of the arrow with the bin 47 as a fulcrum. This connector 34A is configured such that a hook metal fitting 49 provided on a buckle 46 is hooked to a main body member outer joint hook 28, as shown in FIG.

In this embodiment, when the buckle 46 is released, the overall length of the connecting tool 34A becomes longer than before opening, so the connecting tool 34A
When releasing the attachment, an additional effect is that the operation becomes easier than in the previous embodiment.

Furthermore, if the rope 36 is largely loose when the connector 34A is attached, there is a risk that the rope 36 will come off from the main body member 12 before the rope 36 becomes taut.
Since the total length of the connector 34A is reduced by closing,
There is also the added effect that the connector 34 can be attached without requiring great force and without causing a large amount of slack in the rope 36.

Note that, instead of the buckle 46, a hook fitting with a ratchet mechanism that allows sliding only in one direction may be used.
The effects described above can be obtained.

FIG. 6 shows a third embodiment of the present invention, and FIGS. 7 to 9 show details of the main parts.

The connector 34 used in this embodiment has the same structure as that used in the first embodiment.

The length of the lobes 36 is approximately half that of the first embodiment, and two connectors 34 are used for one tire 32. Fasteners 48 and 50 are attached to both the front and back sides of the wheel 40.

The fastener 48 attached to the front side of the wheel 40 as shown in FIG. 6(A) is fixed to the edge of the rim portion 54 by caulking, as shown in detail in FIGS. 7 and 8. There is. As shown in FIG. 9, the end of this fastener 48 on the side of the abutting part with the rim part 54 is formed with continuous teeth 56 having a sharp point, so that the engagement with the rim part 54 is strong. has been done. A hook latching hole 52 is bored at the other end of the fastener 48 . Further, as shown in FIG. 6(B), a fastener 50 attached to the back side of the wheel 40 has the same shape as the fastener 48, and the rim portion 50 has the same shape as the fastener 48.
4 by the same means as described above.

In this embodiment, one connector 34 is disposed on the front side of the tire 32, the hook 38 at one end is engaged with the hook hooking hole 52 of the fastener 48, and the hook 38 at the other end is connected to the first As in the embodiment, the main body member outer joint hook 28
