Description

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

<Prior Art> Conventionally, in order to tighten the anti-slip device for tires wound around the tire so as to bring it into close contact with the tire, a rubber band 21 having elasticity such as rubber is used as shown in FIG. was.

To attach this rubber band 21, first wrap the anti-slip device B' around the tire C, connect both ends of the anti-slip device B', and then
Tighten the inner edge of B' with a tightening rope, then wrap the outer edge of the anti-slip tool B' with a rubber band 2.
Tighten with 1.

As shown in FIG. 15, the anti-slip device B' has its outer edge tightened and fixed by a rubber band 21, so as the tire C rotates at a high speed while driving, centrifugal force is applied to the anti-slip device B'. As the force increases, the rubber band 21 stretches, and the anti-slip tool B' lifts up from the tire C and shifts sideways, posing the risk of the anti-slip tool B' becoming misaligned.

The misalignment phenomenon of the anti-slip tool B' is caused by the excessive load that occurs when the anti-slip tool B' is forced to move.
This is a phenomenon in which B' is largely displaced in the radial direction of tire C. When this misalignment phenomenon becomes severe, the anti-slip device B' that has shifted in the radial direction falls into the inside of tire C, and at the same time the outer circumference of tire C Same anti-slip device
The problem is that it may pop out from the opening 22 on the outside of B' and fall off.

Therefore, although the conventional rubber band 21 has a setting function of temporarily fixing the anti-slip device B' wrapped around the tire C, it is difficult to firmly attach the anti-slip device B' to the tire C. The tightening effect was very weak.

<Technical problem to be solved by the invention> The technical problem to be solved by the invention is that the tightening device has a setting function for temporarily setting the anti-slip device on the tire. The purpose of the present invention is to simultaneously provide a tightening function that allows the tire to adhere tightly to the tire, and a protrusion prevention function that prevents the outer peripheral part of the tire from protruding from the outer opening of the anti-slip device during driving.

<Means for solving the technical problems> The technical means taken by the present invention to solve the above problems is to arrange an inner ring of an appropriate size concentrically inside an outer ring, and to connect the outer ring and the inner ring. A tightening band section is formed by connecting the rings with a connecting arm, and a ring-shaped set band section is arranged close to or in contact with the outer ring of the tightening band section with their centers aligned, and the outer ring and a set band portion are joined at appropriate locations.

<Function> According to the above means, the tightening band portion and the set band portion are joined at appropriate locations on the outer ring and thereby integrated.

When installing, when the set band section is attached along the outer edge of the anti-slip device wrapped around the outer circumferential surface of the tire, this set band section pulls the outer edge of the anti-slip device toward the center of the set band section. , temporarily set the anti-slip device on the tire.

Next, when the outer ring of the tightening band is attached along the outer periphery of the anti-slip device, this outer ring will pull the outer periphery of the anti-slip device further toward the center of the outer ring, causing the anti-slip device to attach to the tire. While setting the temporarily fixed state more strongly, tighten the outer peripheral edge of the anti-slip tool and pull it toward the center of the outer ring. Then, the inner ring and the connecting arm strongly pull the outer ring toward the center of the outer ring, and bring the anti-slip device into close contact with the tire.

When the centrifugal force generated during running increases, the set band portion and the anti-slip device tend to spread. Along with this, the adhesion of the anti-slip device to the tire begins to decrease, but the inner ring and connecting arm resist this expansion of the outer ring and strongly pull the outer ring toward the center of the tire. The outer periphery of the anti-slip tool is strongly tightened to firmly maintain the adhesion of the anti-slip tool to the tire.

Further, the connecting arm and the inner ring close the outer opening of the anti-slip device in the installed state, and in particular, the connecting arm prevents the tire outer peripheral portion from elongating from the opening when a misalignment phenomenon occurs.

<Effects of the invention> Since the present invention is constructed as described above, the tightening device has a setting function for temporarily setting the anti-slip device on the tire, as well as a tightening function for tightly attaching the anti-slip device to the tire. It is possible to simultaneously provide a pop-out prevention function that prevents the outer circumferential portion of the tire from popping out from the outer opening of the anti-slip device during driving.

Therefore, by using only one tightening device, the anti-slip device can be attached to the tire and set, and even when a large centrifugal force is applied during driving, the spread of the anti-slip device can be strongly suppressed, and the anti-slip device can be attached to the tire. It is possible to firmly maintain the adhesion of the non-slip tool, eliminate slippage of the non-slip tool, and prevent the non-slip tool from being cut or falling off due to this slippage, and the outer opening of the non-slip tool can be expanded. Since this opening can be closed by the inner ring and the connecting arm, even if the outer circumference of the tire tries to pop out from the outer opening of the anti-slip device due to misalignment, the tire will not pop out. This can be firmly restrained by the inner ring and the connecting arm, and it is possible to reliably prevent the slip stopper from falling off due to misalignment.

Thus, the intended purpose can be achieved.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

A ₁ to A ₇ in the figure are tightening devices, which prevent slippage when the anti-slip device B for tires as shown in FIG. 13 is wrapped around the tire C as shown in FIG. 14. Attach it to the outer edge of the stopper B, and with the same anti-slip tool B set against the tire C, tighten it so that it sticks strongly, and maintain this state so that it does not slip even when driving at high speeds. It is something.

The tightening device _A1 shown in FIG. 2 are arranged concentrically, and the outer ring 1 and the inner ring 2 are connected by a plurality of connecting arms 3 to constitute a tightening band part _a1 , and one arm is attached to the outer ring ₁ in the tightening band part a1. The ring-shaped set band portions _A2 are arranged so as to be substantially in contact with each other in the outer circumferential direction with their centers coincident, and this outer ring 1
and set band part _a2 are joined at two joints 4, 4.

The outer ring 1 is attached to the outer edge of the anti-slip device B attached to the tire C, and is formed to have a diameter that allows the outer edge to be pulled toward the center of the tire C with an appropriate force. It is formed to have an appropriately smaller diameter than ring 1. A plurality of connecting arms 3 are arranged radially around the outer circumference of the inner ring 2.
and the outer ring 1 are integrally connected.

When both rings 1 and 2 are connected by the connecting arm 3 as described above, the connecting portion of the outer ring 1 is pulled inward and deformed as shown in FIG. 14, but the outer ring 1 and the inner ring 2 are By connecting the connecting positions of the outer ring 1 and the corresponding connecting positions of the inner ring 2, which are determined at equal intervals, to the connecting arm 3, they are accurately concentric.

When installing the anti-slip device B on the tire, the set band part _a2 is first attached to the outer edge of the anti-slip device B, so that the anti-slip device B can be attached to the tire C.
It has the function of being temporarily set in the tightening band portion _a1 , and is formed into a ring shape with a diameter that is approximately the same as or slightly larger than the outer ring 1 in the tightening band portion a1. In addition, when forming the rings to have exactly the same diameter, they are arranged in a superimposed state with the outer ring 1 and joined at appropriate locations.

The tightening device A ₂ shown in FIGS. 2 and 3 has a setting band portion a ₂ composed of two setting rings 5, 5'.
5' and the outer ring ₁ of the tightening band portion a1 are disposed in the outer circumferential direction in close proximity to each other and are joined at two joints 4, 4.

B shown in Fig. 13 is a net-type anti-slip device, in which connection bands b ₂ and b 2 are provided at one end of the net body b ₁ formed in a diagonal grid shape, and the connection bands b 2 and b ₂ are provided at the other end. b ₂ , connecting part b ₃ that connects b ₂ by inserting it,
b ₃ , and a non-stretchable tightening rope b ₄ is attached along the inner edge of the main body b ₁ , and a hook b ₅ is provided on the outer edge for hooking and attaching the tightening device. They are installed at equal intervals.

When attaching the anti-slip device B to the tire C, wrap the anti-slip device B around the circumference of the tire C and attach the connecting band.
Insert b ₂ and b ₂ into the connecting parts b ₃ and b ₃ to connect both ends, and further connect both ends of the inner tightening rope b ₄ and tighten the inside of the net body b ₁ .

Next, a method of tightening the anti-slip device B in the above state by using a tightening device to bring it into close contact with the outer circumferential surface of the tire will be explained using the tightening device _A2 shown in FIG. (see figure).

First, the set ring 5' of the set band part _a2 located at the outermost position is sequentially hooked to each of the hooks _b5 attached to the outer edge of the anti-slip member B in a symmetrical manner to form a ring. Next, attach the inner settling ring 5 in the same manner along each hook _b5 . By attaching this set band part _a2 , the outer edge of the anti-slip tool B is attached to the set band part _a2.
The anti-slip device B is pulled towards the center and the tire C
Set it temporarily in place.

Next, when the outer ring 1 of the tightening band part a ₁ is attached along each of the locking hooks b ₅ in the same way, this outer ring 1 further tightens the outer periphery of the anti-slip device B.
Pull it toward the center to more firmly set the temporary fixing state of the anti-slip tool B to the tire C, tighten the outer peripheral edge of the anti-slip tool B, and pull it toward the center of the outer ring 1. Then, the inner ring 2 and the connecting arm 3 strongly draw the outer ring 1 toward the center of the outer ring 1, and bring the anti-slip member B into close contact with the tire C.

When the centrifugal force generated during running increases, the set band portion _a2 and the anti-slip device B tend to spread. Along with this, the adhesion force of the anti-slip device B to the tire C begins to decrease, but the inner ring 2 and the connecting arm 3 resist the expansion of the outer ring 1 and force the outer ring 1 toward the center of the tire. As a result, the outer peripheral edge of the anti-slip tool B is strongly tightened, and the adhesion of the anti-slip tool B to the tire C is firmly maintained.

In addition, the connecting arm 3 and the inner ring 2 close the outer opening D of the anti-slip device in the installed state, and in particular, the connecting arm 3 prevents the outer peripheral part of the tire C from popping out from the opening D when a misalignment phenomenon occurs. Deterrence without.

The tightening device _A3 shown in FIGS. 4 and 5 has a second
In the tightening device _A2 shown in the figure, the two setting rings 5, 5' and the outer ring 1 are joined by the joint portion 4 at an appropriate position while being in concentric contact with each other in the outer circumferential direction. It is.

In the tightening device _A4 shown in FIGS. 6 and 7, two set rings 5, 5 of exactly the same diameter are overlapped and joined at appropriate positions, and the set band part _a2 is the tightening band part _a1. The outer periphery of the outer ring 1 is in contact with the outer ring 1, and the outer ring 1 is joined to the outer ring 1 at an appropriately positioned joint portion 4.

The tightening device _A5 shown in FIGS. 8 and 9 connects a set band part a2 which is joined to the outer ring ₁ of the tightening band part a1 at a joint part ₄ at an appropriate position with one set ring 5. , two settling rings 5', 5' with a somewhat smaller diameter than this, a total of three settling rings 5, 5',
5', the respective settling rings 5, 5', 5' are arranged with their centers coincident and close to each other,
They are joined and integrated by joints 4 at appropriate locations.

The tightening device _A6 shown in FIGS. 10 and 11 is
The inner ring 2 in the tightening band part _a1 is formed double, and the first inner ring 2a and the second inner ring 2b are connected by an inner connecting arm 3a.
b is connected to the outer ring 1 via the outer connecting arm 3b, and with the two set rings 5, 5' in concentric contact with the outer ring 1, the respective rings 1, 5, 5' are joined by joint portions 4 at appropriate positions. By appropriately increasing the number of inner rings and connecting arms in this manner, the tightening function and the function of preventing the outer circumferential portion of the tire from popping out during driving can be further enhanced.

In addition, in the present invention, as in the tightening device _A7 shown in FIG. 12, the inner ring 2, connecting arm 3, etc. in the tightening band portion _A1 are provided with a core material 6 made of high-tensile synthetic fiber or the like. This portion may be configured to be non-stretchable by providing it internally.

The outer ring of the tightening band part and the set band part may be joined at any number of places, but one or two places are appropriate, and the diameter, thickness, and length of the connecting arm of each ring should also be determined.
