Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a tightening device for a tire slip stopper.

(Prior Art) Conventionally, the tightening device shown in Fig. 7 is attached along the outer edge of the anti-slip device for a tire wrapped around the tire and tightens the anti-slip device against the tire. There is a patent application No. 158339, 1983.

This tightening device B is made of rubber or the like, and includes a required number of connecting arms 32 protruding from the outer periphery of a core ring 31, and an operating ring 33 provided at the outer end of the connecting arms 32. There is. When attached to the anti-slip device D wrapped around the tire C as shown in FIG. It is used by hanging the actuation ring 33, and has the property of generating strong elasticity when the actuation ring 33 is expanded, and the anti-slip device D expands due to the centrifugal force generated while driving, thereby increasing the adhesion force with the tire. This has the effect of preventing the anti-slip device D from dropping from the tire when the anti-slip device D becomes misaligned.

The misalignment phenomenon of the anti-slip tool D is the phenomenon of misalignment of the anti-slip tool D.
When the tire is driven in an unreasonable manner, the excessive load causes the tire to slide in the radial direction. When this misalignment phenomenon becomes severe, the anti-slip device D falls into the inside of the tire C, and at the same time, the tire C The outer periphery of the anti-slip tool may protrude from the opening E on the outside of the anti-slip tool, causing it to fall off.

The tightening device B, which is installed so as to cover the opening E of the anti-slip device D, prevents the outer circumferential part of the tire from protruding from the opening E in the above condition, and prevents the tire from protruding from the opening E in the above-mentioned state, and prevents the anti-slip device D from slipping out of the center due to the phenomenon of misalignment. This prevents the anti-slip device D from falling off even if it shifts significantly in the radial direction.
It is to avoid danger.

(Technical issue) The present invention is an improvement of the aforementioned tightening device.
The technical challenge is to improve the function of preventing the tire peripheral surface from popping out from the outside opening of the anti-slip device, thereby more reliably preventing the anti-slip device from falling off due to positional changes. This is the purpose.

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems are: an actuation ring attached along the outer edge of a tire anti-slip device attached to the outer peripheral surface of the tire; A core ring having a diameter smaller than that of the actuating ring and provided at the center of the actuating ring is formed from a member that expands and contracts while producing elasticity, and non-stretchable connecting arms are directed from the inner peripheral surface of the actuating ring toward the center of the actuating ring in the required number. It is provided protrudingly, and a latching means is attached to the tip of the latching means for attaching and detachably latching to the nucleus ring.

(Function) According to the above means, at the time of installation, the actuating ring is wound around the outer peripheral surface of the tire and attached along the outer edge of the anti-slip device, and then the tip of the connecting arm is pulled toward the center. When the latching means is hooked to the core ring, the actuation ring and the core ring expand, and the elasticity of both rings pulls the anti-slip device toward the center of the tire and brings it into close contact with the tire, while also applying tension to the connecting arm. give.

This has the effect of preventing the adhesion force with the ear from decreasing and also preventing the anti-slip device D from falling off the tire when the phenomenon of misalignment occurs.

The misalignment phenomenon of the anti-slip tool D is the phenomenon of misalignment of the anti-slip tool D.
When the tire is driven in an unreasonable manner, the excessive load causes the tire to slide in the radial direction. When this misalignment phenomenon becomes severe, the anti-slip device D falls into the inside of the tire C, and at the same time, the tire C The outer periphery of the anti-slip tool may protrude from the opening E on the outside of the anti-slip tool, causing it to fall off.

The tightening device B, which is installed so as to cover the opening E of the anti-slip device D, prevents the outer circumferential part of the tire from protruding from the opening E in the above condition, and prevents the tire from protruding from the opening E in the above-mentioned condition, and prevents the anti-slip device D from slipping out of the opening E due to misalignment. This prevents the anti-slip device D from falling off even if it shifts significantly in the radial direction.
It is to avoid danger.

The technical challenge is to improve the function of preventing the tire peripheral surface from popping out from the outside opening of the anti-slip device, thereby more reliably preventing the anti-slip device from falling off due to positional changes. This is the purpose.

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems are: an actuation ring attached along the outer edge of a tire anti-slip device attached to the outer peripheral surface of the tire; A core ring having a diameter smaller than that of the actuating ring and provided at the center of the actuating ring is formed from a member that expands and contracts while producing elasticity, and non-stretchable connecting arms are directed from the inner peripheral surface of the actuating ring toward the center of the actuating ring in the required number. It is provided protrudingly, and a latching means is attached to the tip of the latching means for attaching and detachably latching to the nucleus ring.

(Function) According to the above means, at the time of installation, the actuating ring is wound around the outer peripheral surface of the tire and attached along the outer edge of the anti-slip device, and then the tip of the connecting arm is pulled toward the center. When the latching means is hooked to the core ring, the actuation ring and the core ring expand, and the elasticity of both rings pulls the anti-slip device toward the center of the tire and brings it into close contact with the tire, while also applying tension to the connecting arm. give.

The non-stretchable connecting arm prevents the actuation ring and the cleat from expanding due to centrifugal force, and
Close the outer opening of the anti-slip device when installed,
To prevent an outer peripheral part of a tire from elongating from the opening when a misalignment phenomenon occurs.

(Effects) Since the present invention is as described above, it prevents the anti-slip device and the opening of the anti-slip device from expanding more than a predetermined amount due to centrifugal force during driving, and also prevents slippage due to misalignment. Even when the outer circumferential part of the tire tries to pop out from the outer opening of the stopper, the non-stretchable connecting arms can firmly prevent the tire from popping out, thus preventing the phenomenon of misalignment. It is possible to reliably prevent the slip stopper from falling off.

In addition, since the connecting arm is pulled in toward the center and the connecting means at the tip is hooked onto the core ring, it is installed. Tightening work can be done easily.

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

A in the figure is a tightening device, which is used to tighten the anti-slip device D when wrapping the anti-slip device D for a tire as shown in FIG. 5 around the tire C as shown in FIG. 2. The anti-slip device D is attached to the outer edge and tightened against the tire C.

The members forming the tightening device A include 1 an actuation ring attached to the outer edge of the anti-slip device D, 2 a core ring, 3 a connecting arm protruding from the inner peripheral surface of the actuating ring 1, and 4 a connecting arm. This is a connecting hook that hooks the tip of 3 to the nucleus ring 2.

The actuation ring 1 and the core ring 2 are formed using a material that expands and contracts while producing elasticity, such as rubber, and in the case of both rings 1 and 2 shown in Fig. 1, they are made of synthetic rubber and are integrally formed. It is molded into

The actuating ring 1 is formed into a ring shape having a predetermined length and smaller diameter than the diameter of the outer edge of the anti-slip device D when it is wound around the tire C, that is, the diameter of the opening E.

The core ring 2 has a double structure consisting of an inner ring 2a and an outer ring 2b, and is formed to have an outer diameter of about 1/4 of the operating ring 1, and protrudes from the inner peripheral surface of the operating ring 1 toward the center of the ring 1. It is supported at the center of the actuating ring 1 by the provided support rods 5, 5, and is integrated with the actuating ring 1.

A necessary number of connecting arms 3 projecting toward the center of the actuating ring 1 are provided on the inner circumferential surface of the actuating ring 1 at equal intervals in the circumferential direction. The required number is, for example, five, and these connecting arms 3 are formed a predetermined amount shorter than the length from the operating ring 1 to the outer periphery of the core ring 2, and their central core is made of wire or high-tensile synthetic fiber. A core material 3a is provided inside, and a connecting arm 3
It is constructed so that it does not expand or contract.

A connecting hook 4 that removably hooks onto the nucleus ring 2 is attached and fixed to the tip of each connecting arm 3, so that the tip of the connecting arm 3 can be connected to the nucleus ring 2.

The above-mentioned actuating ring 1 and core ring 2 may be made of materials other than rubber as long as they can expand and contract while producing elasticity; for example, they may be made of a spring or synthetic resin. Any means may be used for the structure as long as it can be detachably hooked to the core ring 2.

In addition, although the above-mentioned core ring 2 has a double structure for improving the tightening force and ensuring fail-safety, the same core ring 2 may also have a triple or more structure, or it may have a structure similar to the tightening device A ₂ shown in Fig. 6. It is also optional to configure it in the shape of a single ring.
It may be attached to the tip of any one of the connecting arms 3 without being supported by the connecting arms 5.

The anti-slip device D shown in FIG. 5 is a net-type anti-slip device, and connecting bands 6, 6 are provided at one end of the net body D' formed in a diagonal lattice shape.
Connecting parts 7, 7 are formed at the other end to insert and connect the connecting bands 6, 6, and a non-stretchable tightening rope 8 is attached along the inner edge of the main body D', and the outer edge is provided with a non-stretchable tightening rope 8. The hooks 9 are attached at equal intervals.

When attaching the anti-slip device D to the tire C, wrap the anti-slip device D around the circumference of the tire C, insert the connecting bands 6, 6 into the connecting parts 7, 7 to connect both ends, and then Connect both ends of the tightening rope 8 and tighten the inside of the net body D'.

The fastener A is used together with two ring-shaped rubber bands F. This rubber band F is sequentially latched along each of the hooks 9 attached to the outer edge of the anti-slip device D, thereby causing the anti-slip device D to be wrapped around the tire.
This is to accurately set the tire against the tire and to pre-tighten it.

Thereafter, the operating ring 1 of the fastener A is hooked along each hook 9 in the same manner as the rubber band F, and then the connecting arm 3 is pulled toward the center.
The connecting hook 4 at the tip of the arm 3 is successively hooked onto the nucleus ring 2.

Therefore, the latch hook 9 provided on the outer edge of the skid device D receives the elasticity of the expanded operating ring 1 and the core ring 2, and the elasticity of the core ring 2 transmitted via the connecting arm 3. and the elasticity of two rubber bands F is added,
By pulling these hooks 9 toward the center of the tire C, the anti-slip device D is brought into close contact with the tire C.

When the centrifugal force generated in the anti-slip tool D exceeds the tightening force between the fastener A and the two rubber bands F, the actuating ring 1 and the rubber bands F begin to spread as shown in Figure 4, but do not expand or contract. The flexible connecting arms 3 prevent them from expanding unnecessarily and prevent the adhesion of the anti-slip device D from decreasing.

Furthermore, the five connecting arms 3 and the core ring 2 close the opening E of the anti-slip device D to ensure that the outer circumference of the tire C does not protrude from the opening E when a misalignment phenomenon occurs. It is intended to prevent

Incidentally, the above-mentioned tightening device A can also be used for a ladder-type anti-slip tool (not shown).
