Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for a rotating body, and more particularly to a mounting device for fixing a non-slip member or the like to a rotating body such as a vehicle tire.

[Background Art] In a vehicle, a non-slip device is mounted on a tire, for example, to prevent the tire from slipping on a snowy road or on an ice burn.
In addition to metal chains, non-metal chains such as rubber or plastic are used.

That is, the metal chain is a highly reliable anti-slip device having extremely large frictional resistance with the road surface, but has the disadvantage of damaging the road surface itself and generating large noise and dust pollution. On the other hand, rubber or plastic non-metal chains have a high slip prevention effect on snowy roads,
This non-metallic chain is also widely used because it has the advantage that the vehicle has good running stability even on a road surface where the amount of snowfall is small due to its flexibility and that the road surface itself is not damaged.

[Problems to be Solved by the Invention] However, in the conventional anti-slip device and the like, there is a problem that it is relatively difficult to attach / detach to / from a rotating body such as a tire, and that a good mounting state cannot be obtained. Was.

That is, the non-slip device, for example, spans the non-metallic chain from the outer surface of the tire to the inner peripheral surface so as to cover the ground contact portion of the tire, and firstly hooks the non-metallic chain on the inner peripheral surface of the tire by a hook or the like. Then, the non-metal chains are also connected to the outer peripheral surface of the tire by hooks or the like, and in that case, they must be performed while applying a predetermined tension.

Therefore, a relatively large force is required to apply the predetermined tension, and it is difficult to obtain a firmly fixed and good mounting state. Was also complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to achieve a good mounting state by firmly fixing a mounted member to a rotating body, and to facilitate a mounting operation. To provide a device for mounting the device.

[Means for Solving the Problems] In order to achieve the above object, an apparatus for mounting on a rotating body according to the first aspect of the present invention is a rotating apparatus for fixing a member to be mounted along an outer periphery of the rotating body. A mounting device provided on at least one side surface of a body, wherein a plurality of connecting pieces having a weight are engaged so as to be movable in a circumferential direction to form an annular member, and the diameter is variable. The annular member and the mounted member are connected to each other, and the diameter of the annular member formed by the plurality of connecting pieces is reduced by centrifugal force acting on the weight when the rotating body rotates, thereby tightening and fixing the mounted member to the rotating body. It is characterized by doing.

The invention according to a second aspect is characterized in that the rotating body is a vehicle tire, and the mounted member is a non-slip member.

Further, the invention according to a third aspect is characterized in that an annular coil spring for inserting an annular member constituted by the plurality of connecting pieces is provided.

[Operation] According to the apparatus for mounting on a rotating body having the above configuration, for example, when a non-slip member, which is a member to be mounted, is mounted on a tire, which is a rotating body, first, the non-slip member is moved along the outer periphery of the tire. And set it in a predetermined position. Then, when the tire, which is a rotating body, is rotated in a fixed state such that the annular member does not separate from the tire, the weight provided on the plurality of connection pieces moves outward due to the centrifugal force of the tire, The size of the ring of the ring-shaped member composed of a plurality of connecting pieces is reduced. Therefore, the mounted member is pulled to the center of the tire, and is firmly fixed to the tire.

In this case, since the mounted member is gradually mounted on the rotating body by the rotation operation, the mounted member is uniformly arranged along the outer periphery of the rotating body, and the tightening force for fixing the mounted member is also uniform. Therefore, a good fixed state can be secured.

Examples Hereinafter, examples of the present invention will be specifically described with reference to the drawings.

FIG. 1 shows a configuration of a device for mounting on a rotating body according to a first embodiment, and the embodiment describes a case where a non-slip member is mounted on a tire of a vehicle.

In the figure, a metal chain 12 that is a non-slip member is provided along the outer circumference of the tire 10, and the metal chain 12 is connected to an annular member 14. That is, in the embodiment, a plurality of connecting pieces 18 having a weight 16 are connected to each other, and the connecting pieces 18 are housed in a spring 20 to form an annular member 14. Is installed.

The spring 20 of the first embodiment can be expanded to the size of the outer periphery of the tire 10, but does not need to have a strong elastic force like the spring used in the conventional non-slip device, and the annular member is It is only necessary to be able to maintain a certain size, and a small elastic force is sufficient.

FIG. 2 shows the structure of the connecting piece 18, and FIG. 3 shows a state in which the connecting pieces 18 are connected. As shown in FIG. It is made of a string-like body of a predetermined length made of plastic fiber or the like, and has a ring portion 18a and a ball portion 18b formed at the tip.
Also, a weight 20 made of lead is fitted into the ball portion 18b,
The two are bonded by an adhesive 22. In this embodiment, the weight 20 has a weight of about 0.3 kg. Then, by passing the loop 18a of the other connecting piece 18 while crushing the loop 18a, the plurality of connecting pieces 18 having the weight 16 are connected to each other to form the annular member 14.

FIG. 3 shows a state in which a plurality of connecting pieces 18 are connected. When the connected annular member 14 is rotated about the center 10a of the tire 10 as shown in FIG. Since the connecting piece 18 is shortened by the force, the length L shown in the drawing of the connecting piece 18 is shortened.

Here, how much centrifugal force acts when a 0.3 kg weight 16 is used will be described. For example, 60km / h
When the vehicle is running, the rotational speed n of the tire 10 is as follows.

That is, the speed per second is 60km / 3600 = 17m / sec.
Assuming that the radius of 0 is 0.3 m, the circumference is 0.3 m × 2π = 1.9 m, so (17 m / sec) /1.9 m = 9 rotations / sec.

The centrifugal force F is represented by F = mr (2πn) ² where m; mass, r; radius, so that F = 0.3 kg × 0.3 (2π × 9) ² = 288 kg (where r = 0.3 m Do).

Thus, when the vehicle runs at 60 km / h, one weight 16 weighs 288 kg, which is 960 times the original weight (288 ÷ 0.3
= 960).

FIG. 4 is a cross-sectional view of the tire and the anti-slip member of FIG. 1 as viewed from the traveling direction. The annular member 14 in the mounting device of the present invention is provided on at least one side surface of the rotating body. However, in the embodiment, it is provided on both sides of the tire 10.

When the anti-slip member of the first embodiment is mounted on the tire 10,
As shown in the figure, the weight W of the weight 16 described above is obtained.
_1, it is necessary to heavier than the weight W ₂ of the combined metal chain 12 and the spring 20 present in the side surface of the tire 10.
That is, as described above, the annular member 14 reduces its annular shape by the centrifugal force acting on the weight 16, but the centrifugal force acting on the metal chain 12 and the spring 20 existing on the tire side faces causes the weight 16 to move inward. This is because the force is generated in the pulling direction and these forces must be considered.
Therefore, in order to utilize the centrifugal force of the weight 16, it is necessary to include a condition of W _1> W _2.

The embodiment has the above configuration, and its operation will be described below.

When attaching the non-slip member to the tire 10, the inner spring 20 is pushed and spread more than the outer periphery of the tire 10,
The metal chain 12 is arranged from the outside to the inside of the tire 10.
In this state, the springs 20, 20 on both sides are pulling the metal chain 12 with a predetermined tension.
12 will not come off the tire 10.

Then, when the vehicle is run, a centrifugal force corresponding to the rotation speed of the tire 10 is applied to the weight 16, and thus the annular member 14 can reduce its annular shape. A strong clamping force is applied to the tire 10, and the metal chain 12 is firmly fixed to the tire 10.

As described above, in the embodiment, since the tightening of the chain is performed by centrifugal force, after placing the chain on the tire 10 as in the related art, it is not necessary to hook a relatively heavy labor, and it is easy to mount the chain. Yes, and the spring 20
By using, the mounting work of the non-slip member can be further simplified.

Also, in the present invention, it can be used in a free size,
There is an advantage that it can be applied to tires having different sizes.
That is, as shown in FIG. 3, the circumferential length of the ring of one connecting piece 18 is L, the radius of the ring is D, and L ₁ = 1 /
When 2L ₂ (L ₂ is the total length), the radius of the ring is also D ₁ = 1
/ 2D ₂ (maximum radius), and the radius D of the ring can be changed according to the degree of shortening of the length L of the connecting piece 18.
Therefore, even when the radius of the tire 10 is different, the non-slip member can be mounted without any problem.

Above it, by the maximum radius D ₂ of the ring larger than the radius of the tire 10, which means that can be passed through the tire 10 into the annular. For example, it is considering the case of Figure 1, even if the maximum radius D ₂ of the annular member 14 slightly larger than the radius of the tire 10, the annular member 14 metal chain 12 at the position of radius D ₁ of the illustrated Can be firmly fixed. Therefore, this annular member 14 is
Can also be arranged on both side surfaces.

In the above-described embodiment, the spring 20 is provided on the annular member 14. However, the spring 20 can be functioned as a non-slip member without providing the spring 20.

Further, in the embodiment, a metal chain 12 is used as a non-slip member.
However, a ladder-type or net-type non-metal chain can also be used.

Further, in the first embodiment, the connecting piece 18 is used as the loop 18
Although a string-like material having a is used, the invention is not limited to this, and other structures can be used. For example, the structure can be as shown in the second embodiment in FIG.

In FIG. 5, the connecting piece 26 is formed of a circular or U-shaped plate having a weight 28 at the tip, and the connecting piece 26 has a slide groove 26a as a whole,
Engagement pin 2 that engages with slide groove 26a of other connecting piece 26
6b is provided. If the plurality of connecting pieces 26 are connected to form an annular member, the engaging pin 26a can slide in the slide groove 26B. Therefore, the size of the annular member can be reduced by the centrifugal force generated in the weight 28 due to the rotation of the rotating body, and for example, a state in which the chain is firmly fixed to the tire can be obtained.

[Effects of the Invention] As described above, according to the present invention, an annular member in which a plurality of connecting pieces having weights are annularly connected is provided on at least one side surface of a rotating body such as a tire. The mounted member is fastened and fixed to the rotating body by reducing the size of the ring of the annular member by the centrifugal force acting on the weight when rotating the member, so that the mounted member such as the non-slip member is rotated. There is an effect that a good mounting state firmly fixed to the body can be obtained and the mounting operation is facilitated.

Further, since the mounted member is tightened by the rotating operation of the rotating body, the mounted member is uniformly arranged along the outer periphery of the rotating body, and the tightening force for fixing the mounted member is also uniform. And a good mounting state is ensured.

Furthermore, according to the present invention, since the size of the annular member has a degree of freedom, it can be used for a free size,
It can be applied to rotating bodies of different sizes.

According to the third aspect of the present invention, a spring is provided along the ring of the annular member to maintain the annular member at a predetermined size. Can be further easily mounted.
