Description

[Detailed description of the invention] <Field of industrial application> The invention relates to a skid device for vehicles that is attached to tires to prevent slips when vehicles such as automobiles drive on snowy or frozen roads. , relates to a connecting device that easily connects a non-slip device in a ring shape when installing a tire.

<Prior Art> When a vehicle such as an automobile travels on a slippery road surface covered with snow or ice, a wire chain type skid device is attached to the tire so as to prevent the vehicle from slipping.

Wire chain type non-slip device for vehicles is No. 4
As shown in the figure, the two side strips C are arranged in parallel at appropriate intervals and are made of steel wire rope, etc., and at both ends there is a connecting member C and a receiving member that receives and locks the connecting member C. D is fixed. Between the two side strips, a large number of short cylindrical anti-slip rings made of metal or synthetic resin are arranged in series and rotatably inserted into a strip made of steel wire rope or the like. A plurality of the formed anti-slip members are arranged in parallel at regular intervals and connected at right angles to the side strips to form a ladder shape.

The anti-skid device applies the anti-slip member to the road contact surface of the tire, the two side strips are respectively located on the side body part on both sides of the tire, and the connecting member and the receiving member are connected to the side body part. Attach by tightening from both sides. In this way, the side strips are connected in a ring shape at the side body of the tire and fastened to the tire, but the size varies depending on the type of tire, and the circumferential length of the side body changes. For this reason, if the length of the side strip is fixed by fixing a connecting member and a receiving member to the ends on both sides, it can only be installed on a specified type of tire, and is not necessary for other types of tires. Sometimes it cannot be used.

In order to prevent such accidents, a connecting member is fixed to one end of the side strip, and a locking hole is drilled in the center of the main body of the connecting member and the connecting member that is connected and locked to it, and the metal wire is shaped into an oval shape. A chain formed by connecting a plurality of formed wheels is fitted into the locking hole of both members, interposed between them, and connected, and the chain is connected according to the circumferential length of the side body of the tire. The length of the side strips can be adjusted by removing or adding rings to the chain.

<Problems to be Solved> However, the individual wheels of the chain that interposes between and connects the connecting member fixed to the end of the side strip and the connecting member are not cut out into grooves that are partially cut out. Therefore, the connection is made by fitting into the locking hole of the connecting member, etc., but if the width of this notch groove is widened to make it easier to attach to the connecting member, etc., the fitting can be done easily.
Although it is easy to fit and unfit, it can come off when not needed and parts can be lost during storage or operation. Therefore, it is better if the width of the notch groove in the wheel body is as narrow as possible, but if it is narrow, it will be difficult to connect it to a connecting member, etc., and it will take time to attach and remove it when attaching it to a tire. In particular, when attaching a skid device to a tire, the speed of attachment is a big issue because the device must be operated quickly under adverse conditions such as snow or ice on the road surface.

<Means for Solving the Problem> The present invention, when connecting the ring body of a chain to a connecting member etc., provides a concave groove in the main body that extends from a locking hole drilled in the main body of the connecting member etc. to the outer edge of the main body and connects the thin walled part. A thin passage groove is formed in a part of the main body so that it can be easily inserted into the narrow notch groove of the ring of the chain, making it easy to insert and remove the ring. The parts other than the thin-walled parts are closed so that the length of the side strips can be adjusted, and at the same time, the ring body is difficult to come off when not needed.

<Example> The present invention will be explained with reference to the drawings. In the anti-skid device 1 shown in FIG. A connecting member 22 is connected to the member 21 via a chain 3 in which a plurality of wheels 31 are connected in succession, and a receiving member 23 is fixed to the other end of the side strip 2.

The two side strips 2 are arranged in parallel with an appropriate interval, and between the side strips 2, a plurality of anti-slip members 4 are arranged in parallel at a constant interval, and are perpendicular to the side strips 2. They are connected to form a ladder shape.

The connectors are shown in FIGS. 2 and 3, and members such as the connecting member 21 fixed to the end of the side strip 2 and the connecting member 22 connected thereto are
As shown in the figure, a locking hole 5 is bored in the center of the plate-shaped main body, and a groove 51 extends from the locking hole 5 to the outer edge of the main body.
A thin wall portion 52 is provided by attaching . The thin portion 52 is a groove through which a cutout groove of a ring body, which will be described later, passes.

As shown in FIG. 3, the chain 3 is made up of a metal wire formed into an oval shape and connected to a plurality of rings 31 each having a notch groove 32 formed by cutting out a part of the metal wire. Notch groove 32
has a width narrower than the thickness of the main body of the coupling member such as the connection member 21, and a width wider than the thickness of the thin wall portion 52.

To connect the chain 3 to a coupling member such as the connecting member 21, align the thin wall portion 52 of the coupling member with the cutout groove 32 of the ring body 31 at the end of the chain 3, and pass it through along the concave groove 31. 31 is inserted into the locking hole 5 and connected to form a connecting tool. Also, the ring bodies 31 of the chain 3 are connected to the cutout grooves 32 of the adjacent ring bodies 31.
If you move them together, you can easily fit them in and out.

In addition, although the connection between the connecting member 21 and the connecting member 22 has been described in the embodiment, the same effect can be achieved even if the connecting member 21 is connected to the connecting member 21 instead of the receiving member 23. The connecting member 22 and the receiving member 23 may be connected to each other by interposing the chain 3 to the connecting member 21 fixed to both ends.

<Operation> When attaching the anti-skid device 1 to the tire, if the side strip 2 is longer than the circumferential surface of the side trunk of the tire, connect the notch groove 32 of the wheel body 31 at the end of the chain 3 to the connecting member 21 or the connecting member 22. The end wheel body 31 is removed from the chain 3 by moving it along the thin wall portion 52 of the wheel body 31 and pulling it out, and then aligning the notch groove 32 of the adjacent wheel body 31 with the notch groove 32 of the wheel body 31 and pulling it out. Continue this operation until the appropriate length is reached. After the end of the chain 3 has been removed, the ring body 31, which has become the new end, is attached to the connecting member 21 and the connecting member 2 by reversing the removal procedure described above.
Connect to 2. In this way, the length of the side strip 2 is adjusted by removing the required number of wheels 31 and shortening the length. In order to lengthen the side strip 2, the necessary number of wheels 32 may be connected by the above-described operation. Therefore, side strip 2
The length can be easily adjusted by attaching and removing the wheel body 31.

<Effects> The side strip of the skid device is connected to the connecting member fixed to the end thereof through a chain, and the connecting and disconnecting of both members and the chain is performed by the connecting member and the main body of the connecting member. a drilled locking hole;
It can be easily attached and detached by aligning the notch groove of the ring body of the chain with the thin part due to the concave groove provided along the outer edge of the main body and moving either one of them. Furthermore, the width of the notched groove of the ring body of the chain fitted into the locking hole of the connection member or coupling member is narrower than the body thickness of the member to which it is fitted, so it will not fall off accidentally. do not have.

Therefore, the length of the side strips can be easily adjusted by attaching and removing the wheels of the chain, and can be used regardless of the size of the tire.
