15, the chains 2 and 3 of the anti-slip device 1 are removed from the storage box 21 by the rails 11 and 15.
12 or stored in this storage box 21 from the rails 11 and 12.

Incidentally, as shown in FIG.
5a is provided so that it can be wound up, hooks 14b and 15b provided at the tips thereof are hooked to the terminal ends of the chains 2 and 3 of the anti-slip device 1, and the supply sprockets 14 and 15 are reversed. , the anti-slip device 1 can be removed from the tire 5 by unwinding both chains 2 and 3.

Next, to explain the chain support mechanism in detail, as shown in FIGS. 1 and 3, a support arm 22 is provided on the outside rail 12 so as to extend substantially horizontally on the outside of the tire 5. A pair of supporting sprockets 23 and 24 are rotatably supported. The guide chain 7 is hung between the support sprockets 23 and 24, and before the anti-slip device 1 is attached to the tire 5, the guide chain 7 is looped around the support sprockets 23 and 24. At the same time, it is arranged in a contracted state between both supporting sprockets 23 and 24. Also, the portion of the guide chain 7 that is routed around one sprocket 24 is connected to a through hole provided near the outlet of the outer rail 12 of the supply mechanism, as shown in FIGS. 1, 5, and 6. 12d into the guide groove 12c, and can move together with the outer chain 3 of the anti-slip device 1 toward the exit portion of the outer rail 12.

Next, to explain the connection mechanism in detail, as shown in FIGS. 4, 5, and 6, a guide groove 12c is connected between the base plate 12a and the cover plate 12b of the outer rail 12 of the supply mechanism. A zigzag groove 25 is formed to extend substantially parallel to the guide groove 12c,
The sliding prefixes 6b of a large number of connecting pins 6 provided on the outer chain 3 of the anti-slip device 1 fit into this cam groove 2.
5. and,
As shown in FIG. 6, this cam groove 25 includes a linear cam portion 25a formed parallel to the guide groove 12c between the inlet portion and the exit portion of the outer rail 12, and the linear cam portion 25a. between the end of the guide groove 1 and the exit of the outer rail 12.
Inclined cam portion 2 formed to approach the 2c side
5b, and while the sliding prefix 6b of the connecting pin 6 is guided inside the linear cam part 25a, the connecting pin 6 is held in a state separated from the engagement hole 7b of the guide chain 7, and the connecting pin When the sliding prefix 6b of 6 approaches the inclined cam 25b, the cam action moves the connecting pin 6 toward the guide groove 12c and engages with the engagement hole 7b of the guide chain 7, so that the anti-slip tool The outer chain 3 of the chain 1 and the guide chain 7 in the extended state are connected to each other.

Next, the structure for arranging the inner chain 2 of the anti-slip device 1 in an annular manner inside the tire 5 will be explained. As shown in FIGS. A large diameter sprocket 26 is provided to rotate integrally with the
A large number of hook-shaped claws 26a are formed on the outer periphery of the hook. As the sprocket 26 rotates, the inner chain 2, which is sent out from the outlet of the inner rail 11 of the supply mechanism, is locked by the claw portion 26a and arranged in an annular shape inside the tire 5.

Next, the operation of the anti-slip device mounting device configured as described above will be explained.

Now, with this device, the anti-slip device 1 is attached to the tire 5.
When installing, the starting ends of the chains 2 and 3 of the anti-slip device 1 are pulled out from inside the chain storage box 21 and guided into the rails 11 and 12 through the supply sprockets 14 and 15. Thereafter, when the motor 16 is rotated in the normal direction, the supply sprockets 14 and 15 are connected to the first

are fed into the rails 11 and 12 in sequence.

When the outer chain 3 of the anti-slip device 1 approaches the exit portion of the rail 12, the sixth
As shown in the figure, the connecting pin 6 provided on the outer chain 3 is moved toward the guide groove 12c by the action of the inclined cam portion 25b of the cam groove 25, and the forked engagement portion 6a is connected to the guide chain 7. The outer chain 3 of the anti-slip tool 1 and the guide chain 7 are connected to each other. Therefore, when the tire 5 is rotated counterclockwise for the first time in this state, the outer chain 3 is sent out from the outlet of the rail 12, and the guide chain 7 is connected to the outer chain 3 and extended. At the same time, the chains 3 and 7 are sequentially let out from between the supporting sprockets 23 and 24, and are arranged in an annular manner on the outer side of the tire 5, as shown by the chain lines in FIG.

On the other hand, as is clear from FIGS. 3 and 8, the inner chain 2 sent out from the outlet of the inner rail 11 is stopped by the outer peripheral pawl portion 26a due to the rotation of the large diameter sprocket 26 as the tire 5 rotates. Then, they are arranged in an annular shape inside the tire 5. Therefore, the anti-slip band 4 provided between both chains 2 and 3 is disposed across the outer circumferential contact surface of the tire 5, as shown by the chain line in FIG.

In this way, both chains 2 of the anti-slip device 1,
3 are all arranged on the inside and outside of the tire 5, the guiding chain 7 also connects to the supporting sprocket 2.
Outer chain 3 is removed from between 3 and 24 and stretched.
At the same time, the anti-slip device is placed on the outside of the tire 5, and the work of installing the anti-slip device is completed. In this installed state, the tension spring 8 is attached to the guide chain 7.
Because a contraction force is always acting due to the action of
A contraction force toward the rotational axis of the tire 5 is applied to the tire 5, and the anti-slip band 4 is securely fixed to the outer circumferential contact surface of the tire 5.

Next, when removing the anti-slip device 1 attached to the tire 5, the chain 2 of the anti-slip device 1,

As shown in FIG.
b, 15b, and the outer chain 3
A part of the guide chain 7 corresponding to the terminal end of the guide chain 7 is hung on one of the supporting sprockets 24. Thereafter, when the motor 16 is reversed and the tire 5 is rotated clockwise in FIG. When it is disengaged from the engagement hole 7b, the connection between the outer chain 3 and the guide chain 7 is released, and the chains 2 and 3 of the anti-slip device 1 are retracted from the rails 11 and 12 by reversing the supply sprockets 14 and 15. It is stored in the box 21, and the guide chain 7
is rotated between supporting sprockets 23 and 24 in a contracted state.

This concludes the explanation of the configuration and operation of this embodiment, but the present invention is not limited to this embodiment. For example, a support mechanism for the guide chain 7 may be provided inside the tire 5, so that the tire 5 The structure of each part may be arbitrarily changed and embodied without departing from the spirit of the invention, such as configuring both the inner and outer chains 2, 3 of the anti-slip tool 1 to be connected to the guide chain 7 on both the inner and outer sides, without departing from the spirit of the invention. is also possible.

(Effects of the Invention) As detailed above, the present invention provides an anti-slip device comprising two chains and a large number of anti-slip bands provided at predetermined intervals between both chains.
In a mounting device that circumferentially attaches to a tire, the chains are arranged parallel to each other so that the chains are arranged substantially annularly on both the inner and outer sides of the tire, and the anti-slip band is arranged across the outer circumferential contact surface of the tire. a supply mechanism that supplies the inside and outside of the tire; and a chain that is provided corresponding to at least one of the inside and outside of the tire and that supports an extensible and retractable annular guide chain as it passes through the vicinity of the outlet of the supply mechanism. a support mechanism; and a connection mechanism that connects the guide chain to the chain of the corresponding anti-slip device at predetermined intervals in an extended state near the outlet of the supply mechanism, and And by arranging the chain of anti-slip devices in a ring shape on the side of the tire, it is possible to extremely easily attach anti-slip devices to tires, which was extremely troublesome in the past. This provides an excellent effect in that the stopper can be securely attached to the tire in close contact with the tire.
