Description

  The present invention relates to an anti-slip device mounted on a tire of an automobile.

  The anti-slip device exemplified in Patent Documents 1 and 2 is fitted with a U-shaped anti-slip body from the outer peripheral side of an automobile tire. Several anti-slip bodies, for example, 2 to 4, are arranged at almost equal intervals on the entire circumference of the tire, and the adjacent ones are connected. Several anti-slip bodies are fitted into the outer periphery of the tire in a ring and attached to the tire. When the anti-slip device is removed from the tire, the anti-slip bodies are separated from each other and the anti-slip body is removed from the tire.

  The U-shaped anti-slip body includes a U-shaped member on the front side and a U-shaped member on the rear side in the tire rotation direction when the automobile moves forward, and an inner linear member along the inner side surface of the tire. Or in addition to these members, the outer linear member along the outer surface of a tire is provided. The U-shaped members on the front side and the rear side are made of U-shaped curved bars, and have a transverse portion that crosses the tire contact surface, an outer portion that extends along the outer surface of the tire, and an inner portion that extends along the inner surface of the tire. The inner linear member connects the inner portions of the front U-shaped member and the rear U-shaped member.

[Issues of background technology]
In the anti-slip device as described above, it is desired that the anti-slip member fitted to the outer periphery of the tire does not shift with respect to the tire while the automobile is running. When the non-slip body is displaced, the anti-slip effect is reduced. In addition, it is desirable that the connecting member that connects the anti-slip bodies is not separated while the automobile is running. When the connecting member is separated, the anti-slip body is detached from the tire. In addition, the outer diameter of the tire of an automobile is reduced due to the contact surface being worn by the running of the automobile. It is desirable that the non-slip device can be used regardless of the amount of tire wear.

[Idea for solving problems]
In the anti-slip device as described above, in a state where several anti-slip bodies are arranged and connected to the entire circumference of the tire to form a ring, the connecting member that connects the anti-slip bodies to each other is elastically applied by a spring or rubber. I decided to pull it toward the center. Then, the anti-slip body is pressed against the outer periphery of the tire regardless of the amount of wear of the tire. It becomes difficult to slip with respect to the tire.

  Moreover, the connection tool which connected connection members decided to lock in a connection state. And when pulling a connection member to the center side of a tire, it decided to maintain the connection locking state of a connection tool with the tensile force. The connecting member that connects the anti-slip bodies becomes difficult to separate.

  Specifically, a lock mechanism that locks the connector in a connected state is provided. The locking mechanism is configured to be locked by moving the movable member and unlocked by moving in the opposite direction.

The connector is provided with a locking mechanism that locks in the connected state, and the locking mechanism is configured to lock by moving the movable member and unlock by moving in the opposite direction,
A tension tool is provided to pull the movable member of the locking mechanism of the coupling tool toward the center side of the tire with an elastic force,
With several anti-slip bodies arranged around the entire circumference of the tire and connected to form a ring, the connecting member connecting the anti-slip bodies is pulled to the center of the tire with a tension tool, and the anti-slip body is moved to the outer periphery of the tire. In addition to pressing, the movable member of the lock mechanism is configured to be maintained in the locked position by a tension tool.

2) In the tire anti-slip device,
The tension tool is characterized in that the same number of elastic cords as the anti-slip body are radially coupled, the ends of the elastic cords are used as hooks, and the hooks are hooked on the movable member of the lock mechanism.

3) In the tire slip prevention device of 1) above,
The tension tool is an elastic string ring, and the elastic string ring is hooked on the movable member of each lock mechanism.

  The anti-slip body is pressed against the outer periphery of the tire with a tension tool. It becomes difficult to slip with respect to the tire. Moreover, the connection tool of a connection member is maintained in a connection locked state with a tension tool. The connecting member that connects the anti-slip bodies becomes difficult to separate.

Then, as shown in FIGS. 5 to 7, the movable member 36 is in the locked position, and the groove of the restraining portion 38 is fitted into the link 30 with the connecting pin 26 and the retaining link 32, and the retaining link 32 is Restrained by the link 30 with the connecting pin 26, the free end with the ridiculous hole 34 of the retaining link 32 cannot be raised. The stopper is not released and the connected state is maintained.

  Conversely, when unlocking, the movable member 36 is moved to the side opposite to the center of the tire T. Then, as shown in FIGS. 8 and 9, the movable member 36 is in the unlocked position, and the groove of the restraining portion 38 is pulled out from the link 30 with the connecting pin 26 and the retaining link 32, and the retaining link 32. The restraint is released, and the free end with the stupid hole 34 of the retaining link 32 can be raised.

  A tension tool is provided that is attached to the anti-slip bodies 1, 1 a to 1 c that are arranged and connected to the entire circumference of the tire T to form a ring. As shown in FIG. 1, the tension tool radially couples the same number of spiral springs 41 as the anti-slip bodies 1, 1 a to 1 c, and connects the ends of the three spiral springs 41 having the same length to hook-like hooks, respectively. 42. When the tension tools 41 and 42 are attached to the anti-slip bodies 1a to 1c, the hook-shaped hook portions 42 are respectively hooked on the tension portions 39 with the hook holes of the lock mechanism, and the three helical springs 41 are attached to the tire T. From the center position, it stretches radially toward the three lock mechanisms 36 to 39 and is tensioned.

  When the tension members 41 and 42 are attached to the anti-slip bodies 1a to 1c, the movable member 36 of each lock mechanism is pulled toward the center side of the tire T by the elastic force of the tension members 41 and 42. If the movable member 36 is in the unlocked position, the movable member 36 moves to the locked position and is maintained in the locked position. If it is in the locked position, it is maintained in that locked position. At the same time, the center positions of the front and rear connecting members 21 and 22 provided with the lock mechanisms 36 to 39 are pulled toward the center of the tire T by the elastic force of the tension members 41 and 42. The front and rear connecting members 21 and 22 connected by the connecting tools 23 to 26 are tensioned. The three anti-slip bodies 1, 1 a to 1 c connected to the wheels by the connecting members 21 and 22 are pressed against the outer periphery of the tire T. It becomes difficult to shift with respect to the tire T.

  When the anti-slip device is mounted on the tire T, the three anti-slip bodies 1a to 1c are fitted to the outer periphery of the tire T and arranged at almost equal intervals around the tire T, and the rear side of the anti-slip member The connecting member 22 is connected to the connecting member 21 on the front side of the rear non-slip body by a connecting tool to prevent the connecting member 22 from coming off. The locking mechanisms 36 to 39 move the movable member 36 to the locking position and lock it. After making the anti-slip bodies 1a to 1c into a ring, the tensioner hooks each of the hook portions 42 to the pull portion 39 of the lock mechanism. Then, as for each lock mechanism 36-39, the movable member 36 is maintained in a locking position. Further, the anti-slip bodies 1 a to 1 c are pressed against the outer periphery of the tire T.

  When the anti-slip device is removed from the tire T, each hooking portion 42 of the tension tool is detached from the tension portion 39 of the lock mechanism. After removing the pulling tools 41 and 42, each lock mechanism moves the movable member 36 to the unlock position. After unlocking, each connector is released and released. After separation of the front and rear connecting members 21 and 22, the anti-slip bodies 1 a to 1 c are extracted from the tire T.

[Second Example (see FIGS. 14 to 17)]

It is shifted to the front connecting member 21 side from the pin through hole position. In the same manner as in the first example, the movable member 36 penetrates the flat plate portion 37 with a pin through hole into the extended outer portion of the pin 31 and is sandwiched between the retaining link 32 and the spiral spring 33, and has a groove-shaped cross section. A constraining portion 38 having a shape is disposed on the side opposite to the center of the tire T, and a tension portion 39 with a hooking hole is disposed on the center side of the tire T. The movable member 36 is movable in an arc shape in the substantially radial direction of the tire T and in the transverse direction of the connecting members 21 and 22.

  At the time of locking, the movable member 36 rotates around the extended outer portion of the pin 31 to move the restraining portion 38 and the tension portion 39 in an arc shape toward the center side of the tire T. Then, as shown in FIGS. 14 and 15, the movable member 36 is in the locking position, and the groove of the restraining portion 38 is fitted into the link 30 with the connecting pin 26 and the retaining link 32, and the retaining link 32 The free end with the idiot hole 34 will not rise.

  On the contrary, at the time of unlocking, the movable member 36 rotates in the opposite direction, and moves the restraining portion 38 and the tension portion 39 in an arc shape on the opposite side to the center of the tire T. Then, as shown in FIGS. 16 and 17, the movable member 36 is in the unlocked position, and the groove of the restraining portion 38 is pulled out from the link 30 with the connecting pin 26 and the retaining link 32, and the retaining link 32. The free end with the foolish hole 34 can be raised.

[Third example (see FIG. 18)]

The hook part 42 is provided. When the tension tools 41 and 42 are attached to the anti-slip bodies 1a to 1c, the hook-shaped hook portions 42 are respectively hooked on the tension portions 39 with the hook holes of the lock mechanism, and the three helical springs 41 are equilateral triangles. Stretch to shape and get nervous.

  When the tension members 41 and 42 are attached to the anti-slip bodies 1a to 1c, the movable member 36 of each lock mechanism is pulled toward the center of the tire T by the elastic force of the tension members 41 and 42, and is maintained in the locked position. At the same time, the center positions of the front and rear connecting members 21 and 22 provided with the lock mechanisms 36 to 39 are pulled toward the center of the tire T by the elastic force of the tension members 41 and 42. The front and rear connecting members 21 and 22 are tensioned. The antislip bodies 1, 1 a to 1 c are pressed against the outer periphery of the tire T.

Is changed to “the configuration of the inner linear member 4 and the outer linear member 9”. Further, the tension tool is changed from “a configuration in which several spiral springs 41 are coupled” in the first example to “a configuration including one rubber ring 47”.

  As shown in FIG. 19, the outer linear member 9 is a chain formed by connecting a large number of plate-like links rotatably with pins, like the inner linear member 4. The chain 9 has a front end rotatably attached to the front outer connecting plate 5 and a rear end rotatably attached to the rear outer connecting plate 7 with a pin. The outer linear member 9 connects the outer portion 2 b of the front U-shaped member 2 and the outer portion 3 b of the rear U-shaped member 3.

  Further, the outer linear member 9 is provided with a hook-like hooking portion 46 at the center position. In the lock mechanisms 36 to 39, the tension portion 39 is formed in a hook shape. The tension tool is a single circular synthetic rubber ring, rubber ring 47. When the tension tool 47 is attached to the anti-slip bodies 1a to 1c, the tension tool 47 is hooked on the hook-shaped tension part 39 of the lock mechanism and the hook-shaped hook part 46 of the outer linear member 9, and is stretched into a regular hexagonal shape and is tensioned.

When the tension tool 47 is attached to the anti-slip bodies 1a to 1c, the movable member 36 of each lock mechanism is pulled toward the center of the tire T by the elastic force of the tension tool 47 and is maintained in the locked position. At the same time, the center position of the front and rear connecting members 21 and 22 and the center position of the outer linear member 9 are pulled toward the center of the tire T by the elastic force of the tension tool 47. The connecting members 21 and 22 and the outer linear member 9 are tensioned. The antislip bodies 1, 1 a to 1 c are pressed against the outer periphery of the tire T.
