Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a tightening band attachment for a tire anti-slip device.

<Prior art> Conventionally, when attaching a tightening band, as shown in FIG. The ring-shaped rubber tightening band 22 is stretched by hand and hooked one by one, or a plurality of bands are hooked one after another.

On the other hand, the tightening band 22 used has a relatively weak contractile force so that it will not be difficult to operate even for women who are not very strong. However, after installation, the tightening force on the outside of the anti-slip net became weaker, and as the vehicle ran at higher speeds, there was a risk that the tightening band 22 would stretch and expand due to the centrifugal force caused by the rotation of the tire D.

On the other hand, in order to eliminate the risk of the anti-slip device C rising above the tire D surface or coming off from the tire D due to the extension of the tightening band 22 as described above, the diameter is made smaller. tightening band 2 by increasing the shrinkage restoring force by changing the thickness, etc.
By increasing the tightening force of 2 and using a number of such tightening bands 22, the tightening bands 22 are prevented from stretching during driving, and the anti-slip device C is securely attached to the tire D. I tried to keep it in close contact with the surface.

By the way, when the tightening bands 22 are hooked along the respective hooks 21 arranged in a ring on the side surface of the tire D after the anti-slip device C is installed, the tightening bands should be mutually symmetrical. By sequentially latching on the symmetrically located latching hooks 21, it can finally be attached in a ring shape, but the later the latching operation on the latching hooks 21 is done, the more the shape of the tightening band after latching changes. The closer the shape is from a polygon to a ring shape, the more tensile force is required during the latching operation.

Therefore, when using the tightening band 22 which has a very large tightening force as described above, the tightening band 22 must be stretched by hand and hooked onto all the hooks 21 due to the strong contraction force. It is difficult to attach the belts 22 in a ring-like manner and to perform this operation on a plurality of tightening bands 22, especially in the case of a weak woman or the like.

<Technical Problem> The technical problem to be solved by the present invention is to provide a tightening band mounting device that allows the tightening band to be latched across each latching hook without requiring excessive force. Our goal is to provide the following.

<Means for solving the technical problems> The technical means taken by the present invention to solve the above problems is to form the fixture main body into an appropriate shape using a material with appropriate hardness, and An operating hole is formed on one end of the tool body so that the tightening band latching hook on the side edge of the anti-slip tool can be loosely fitted from the outside and slidable, and the other end is provided with an operating hole that can be slid from the outside. It is characterized by a recessed operating groove of an appropriate depth that can be inserted loosely.

<Function> After the tire anti-slip device is attached to the tire, the tightening band is hooked to one or more hooks located at appropriate locations. In this state, hook the part inside the operation hole of the tightening band attachment tool to an appropriate position that is not hooked to the hook on the tightening band, and pull the tightening band in the outer circumferential direction. The hole is loosely engaged with the tip of the hook from the outside.

After that, when this fitting is slid in the outer circumferential direction using the tip of the hook as a fulcrum, the fitting hooking part of this tightening band that tries to contract and restore its shape in the inner circumferential direction will move toward the tip of the fitting. It is guided to the connecting part at the tip of the hook, slides down from the fitting having an appropriate hardness, moves to the hook, and is hooked thereon. The operation of locking the tightening band through the operation hole of the fixture is sequentially applied to each of the symmetrically located locking hooks.

Further, another tightening band is hooked to one or more hooks located at appropriate positions. In this state, hook the part inside the operating groove of the tightening band attachment tool to an appropriate position that is not hooked to the hook on the tightening band, and then pull the tightening band in the outer circumferential direction. A tightening band with a groove loosely fitted along the tip of the latching hook, and one or more tightening bands being latched across all the latching hooks, starting from the back of the rear end of the fixture with this operating groove. Bring it into contact with the outer circumferential surface. After that, when the tightening band fixture is slid in the outer circumferential direction using the outer circumferential surface of the previous tightening band at this position as a fulcrum so that the operating groove crosses the hook, the tightening band fixture is moved in the inner circumferential direction. The fitting hooking part of the tightening band that is about to shrink and restore is guided by the rear end side of the fitting that has an operating groove, and then slides down from the fitting that has an appropriate hardness and attaches to the hook. It moves and is latched onto this. The latching operation of the tightening band using the operating groove of this fixture is sequentially applied to the symmetrically located latching hooks.

<Effects of the Invention> Since the present invention is configured as described above, it has the following effects.

Hook and pull the tightening band to the part inside the operating hole of the mounting tool, and loosely lock the operating hole to the tip of the hook from the outside, and also tighten the tightening band to the part inside the operating groove of the mounting tool. Hang the tightening band on the hook and pull it, align the operating groove loosely along the tip of the hook from the outside, and use this principle to slide the operating groove into the hook by sliding operation. The tightening band can be hooked, and therefore the tightening band can be easily attached without requiring excessive force.

When the first tightening band is installed using the operating hole of the fixture, and the second and subsequent tightening bands are installed using the operating groove, the operating hole is loosely engaged with the tip of the hook. The first tightening band can be securely installed by operating the
By operating the operation groove by loosely fitting the locking hook with the first tightening band as a fulcrum, the second and subsequent tightening bands can be attached reliably and quickly.

Since it is made of a material with appropriate hardness, when the tightening band is moved from the fixture to the hook by sliding operation, the tightening band can be moved smoothly and instantly with little frictional resistance. It can be moved.

Since unreasonable force is not required for the tightening operation, it can be applied to tightening bands with even stronger tightening force, thereby increasing the tightening force.
The adhesion of the anti-slip device to the tire can be further improved.

Thus, the intended purpose can be achieved.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. The illustrated tire anti-slip device is of a net type.

FIGS. 1 to 3 show a tightening band attachment A for a tire anti-slip device in which the present invention is implemented.

The tightening band fixture A is made of a material having appropriate hardness, such as ABS resin, AAS resin, acrylic resin,

It has an opening and an operating groove _A2 is provided on the other end.

As shown in Fig. 3, the operating hole _A1 is formed to an appropriate size, and the front side is formed with an appropriate inclination toward the tip. Tightening band latching hook _b1 on the side edge of stopper B is designed to allow sliding operation by inserting it through the outside. The size and shape of this operation hole _a1 are appropriately set by the latching hook _b1 . Further, when using the latch hook fixture A, the first tightening band 2 is attached using this operating hole _a1 .

The operation groove _a2 is recessed with an appropriate width and depth on the rear end side to form support legs 1, 1 on both sides,
It is formed with an appropriate inclination toward the rear end, and is adapted to be freely slidable by fitting loosely into the hook _b1 as shown in FIG. 9. The size and shape of the operating groove _a2 are appropriately set by the latching hook _b1 . Also, when using the fixture A, the second and subsequent tightening bands are attached using this operating groove _a2 .

Appropriate unevenness is formed on the front side (FIG. 1) and back side (FIG. 2) of the tightening band fixture A to facilitate operation.

Note that this tightening band fixture A is not limited to the above-mentioned embodiment, and may be formed into an elongated rectangular shape, or may be made of a softer material than the above-mentioned one, etc.
Shape, thickness, material, etc. can be set arbitrarily.

Next, according to FIGS. 4 to 12, a tightening band with a strong tightening force and having strong elasticity is attached to the anti-slip device A attached to the tire D using the tightening band attachment device A configured as described above. 2 will be explained as to how to install it as shown in FIG.

After attaching tire anti-slip device A to tire D,
The first tightening band 2 is hooked to one or more hooks _b1 located at appropriate positions (see FIG. 12). In this state, insert the tightening band fitting A into the tightening band 2 from the tip with the operation hole a ₁ , move it in the outer circumferential direction, and tighten the tightening band at the rear part of the fitting A from the operation hole a ₁ . 2. Bring the tightening band into contact with the appropriate position that is not latched on the latching hook b ₁ in 2, and then move the tightening band toward the outer periphery by pulling the clasp A slightly toward you. Pull the tightening band 2 (Fig. 4) and return it to the tire D side so that the operating hole _a1 is loosely engaged with the tip of the hook _b1 from the outside (Fig. 5). ).

After that, when this fitting A is slid in the outer circumferential direction using the tip of the hook b ₁ as a fulcrum, the fitting hooking portion of this tightening band 2 tries to contract and recover as it moves in the inner circumferential direction. (101) is guided to the connecting part between the tip of the fixture and the tip of the hook, slides from the fixture A to the hook _b1 , and is hooked thereon (Figures 6 and 7). . The latching operation of the tightening band 2 through the operating hole a ₁ of the fixture A is sequentially applied to each symmetrically located latching hook b ₁ , and the first tightening band 2 is attached to all the latching hooks.
b Hook it on ₁ and install it in a ring shape.

Next, tighten the second tightening band 3 in the same way, first attaching the hook b ₁ at one or more places at an appropriate position.
Hang on. In this state, put the tightening band fitting A into the second tightening band 3 from the rear end side, move it in the outer circumferential direction, and insert the front part of the fitting A from the operation groove a ₂ into the tightening band 3. Bring the tightening band 3 into a latched state on the fixture A by making it come into contact with the appropriate position that is not latched on the latching hook b ₁ , and then move it toward the outer circumference by pulling the fixture A slightly toward you. Pull the tightening band 3 (Fig. 8) and return it to the tire side so that the operating groove is loosely fitted along the tip of the latch hook B ₁ , and then tighten the operating groove A ₂ on both sides of the support legs 1. , 1 is brought into contact with the outer peripheral surface of the first tightening band 2 (FIG. 9). After that, attach the tightening band fixture A.
When the operating groove A ₂ is slid toward the outer circumference with the outer circumferential surface of the tightening band at this position as a fulcrum along the hook B ₁ in a crosswise manner (Fig. 10), it shrinks and restores itself toward the inner circumference. The attachment A hooking part (101) of this tightening band that you are about to use is in the operating groove.
It is guided by the rear end side of fixture A where _a2 is located, and is slid down from fixture A to hook _b1 , where it is latched (FIG. 11). The latching operation of the tightening band 3 using the operating groove a ₂ of the fixture A is sequentially applied to each symmetrically located latching hook b ₁ ,
The second tightening band 3 is hooked onto all the hooks _b1 and attached in a ring shape (Fig. 13).

When installing the third and subsequent tightening bands, use the operating groove _A2 on the rear end side of the mounting tool A, and
When loosely fitting a ₂ into the hook b ₁ , the supporting legs 1, 1 should be brought into contact with the outer peripheral surfaces of the plurality of tightening bands 2, 3 that have already been attached, and then the support legs 1, 1 should be brought into contact with the outer circumferential surfaces of the plurality of tightening bands 2, 3 that have already been attached, and the Hook it onto each hook _b1 .
