DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a non-slip mounting device. More particularly, the present invention relates to a non-slip mounting device that can securely and reliably mount a non-slip on a wheel with a simple operation.

[0002]

2. Description of the Related Art Conventionally, in order to travel on slippery roads such as snowy roads, it is common practice to attach a non-slip such as a tire chain to a wheel. The task is very laborious and time consuming.

[0003] In recent years, various types of tire chain attachment / detachment devices have been proposed which allow easy attachment / detachment of tire chains.

[0004] For example, in the tire chain attaching / detaching device described in JP-A-8-282226 and JP-A-9-150614, a tire chain is previously stored in a storage case provided inside a tire house of a vehicle body. Things. In these devices, when the tire chain is mounted, the tire chain is detached from the storage rail inside the storage case and engaged with a ring provided on the tire wheel, or the tire chain is directly held, so that the tire chain is mounted. I can do it.

[0005]

However, in these conventional tire chain attaching / detaching devices, it is necessary to temporarily separate the tire chain from the storage rail or the ring on the tire side when the tire chain is attached or detached. Because it is difficult to control, and because it is attached to and detached from and fixed to the storage rails or wheels using the rigidity of the tire chain itself, it can be used for vehicles that use rubber tires that flexibly deform depending on the road surface conditions and vehicle weight. However, there is a problem that the tire chain must have a rigidity that can be reliably attached and detached and firmly fixed, and a flexibility that can be deformed like a tire.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a non-slip mounting device capable of securely and reliably mounting a non-slip on a wheel with a simple operation. And

[0007]

A non-slip mounting device according to the present invention is a non-slip mounting device for detachably mounting a plurality of non-skids on a ground surface of a wheel. A freewheel fixed rotatably independently of the wheel on the same rotation axis as the wheel, and a plurality of fixing mechanisms slidably guided around the periphery of the freewheel, respectively, wherein both ends of the non-slip are provided. A fixing member fixed to each of the fixing mechanisms on both side surfaces of the wheel, and a fixing member for detachably fixing the fixing mechanism to the vehicle body, and fixing the fixing mechanism to the vehicle body via the fixing member, thereby preventing the slip. Are arranged separately and separated from the ground surface of the wheel, are prevented from rotating together with the wheel together with the free wheel, and the fixing mechanism is separated from the fixing member to release the free wheel. By sliding along the periphery of the eel, the non-slip spreads along the outer shape of the wheel and is mounted on the ground contact surface, and rotates together with the freewheel in the same manner as the wheel. It is.

[0008] The freewheel on one side of the wheel is fixed to the first one of the fixing mechanism, and the freewheel on the other side of the wheel is fixed to the last one of the fixing mechanism. An interlocking mechanism that engages the freewheel with a wheel when the fixing mechanism is unlocked from the vehicle body in conjunction with a member, wherein the freewheels on both side surfaces,

The last non-slip lock is released. At the same time, since the operation piece 27 is also separated from the freewheel 4, the input piece 3 is also provided on the second operation section 15 side.
Since there is no pressing force, the engaging piece 33 meshes with the tooth row 34 by the urging force of the compression coil spring 35. Thereby, the other freewheel 4 is also connected to the wheel W.

Further, as shown in FIG. 15, all the anti-skids 1 are wound around the wheel W, and when the wheel W rotates in this state, the engagement portions 17, 18, 19, 20 cause the projections 11 to move the projection 11 of the wheel W. By urging in the direction opposite to the direction of rotation, all the cleats 1 are tightened further against the wheels W.

Finally, as shown in FIG. 16, the casings 22, 28, 2 are manually or electrically driven.
When the wheels 9 and 36 are moved away from the wheel W, the mounting of the non-slip 1 is completed.

Next, a procedure for removing the non-slip 1 of the non-slip mounting device according to the present embodiment will be described with reference to FIGS.

As shown in FIG. 17, all casings 21, 22, 28, 29, and 36 of the first and second operation portions 14, 15 are moved in a direction approaching the wheel W by manual or electric drive. Let it.

As a result, as shown in FIG.
The projections 11 at one end of the first slip stopper 1 are fixed by the engagement portions 16 and 17, and at the same time, the input piece 31 is pressed by the operating piece 23 with a pressing force equal to or greater than the urging force of the compression coil spring 35 (see FIG. 17). By being pushed, the engagement piece 33
Is disengaged from the teeth 34. Therefore, one freewheel 4 becomes free with respect to the wheel W.

Next, as shown in FIG. 19, the projection 11 at the other end of the first slip stopper 1 is locked by the engagement portion 20, and the fixing of the first slip stopper 1 is completed.

Thereafter, as shown in FIG. 20, the second and subsequent slip stoppers 1 are sequentially fixed. At this time, the link arm 8 is smoothly folded by the contraction force of the tension coil spring 9 (see FIG. 1).

Then, as shown in FIG. 21, one end of the last slip stopper 1 comes into contact with the adjacent slip stopper 1 and is fixed.

After that, as shown in FIG. 22, the protrusion 11 at the other end of the non-slip 1 is fixed to the engagement portions 18 and 19, and at the same time, the input piece 31 is moved by the operation piece 27.
By being pressed with a pressing force greater than the urging force of the compression coil spring 35 (see FIG. 21), the engagement piece 33 is released from engagement with the tooth row portion 34, and the other freewheel 4 is free with respect to the wheel W. become. As a result, the removal of the antiskid 1 is completed.
