Abstract

PURPOSE:To prevent a dust pollution by burying holders having a cross-section configuration of a curtain-rail form and detachably mounting projected antiskid parts in a tire at given intervals. CONSTITUTION:Holders 1 having a cross-section configuration of a curtain-rail form have been buried in a tire 4. On the one hand, antiskid parts 3 are formed in a state having a cross-section configuration of a projected form and controls 2. And antiskid parts 3 are provided being inserted into holders 1 grooves from a side direction as required. Also, antiskid parts 3, when unrequired, are released from holders 1. This constitution enables to prevent a dust pollution and noises as antiskid parts 3 can be easily installed and released according to a required or unrequired state of spikes.

Description

[Detailed description of the invention] The present invention relates to a tire anti-slip device.

To prevent tires from slipping on snowy roads, spikes are driven into the tires or chains are installed, but the former causes significant damage to roads due to the spikes, and the resulting dust pollution has become a major social problem. .

The latter type of chain has the major drawbacks of not only lacking in durability and being uneconomical, but also providing poor riding comfort and being extremely troublesome to attach and detach.

The present invention has been made to solve the above problems, and is completely different from the conventional technical concept of inserting or removing a non-slip material as needed into a holder built into a tire. The purpose is to provide a new type of anti-slip device for tires.

The present invention will be described in more detail below with reference to the drawings.

1 to 3 show a first embodiment of the present invention. As shown in the drawings, a holder 1 having a curtain rail shape and a convex cross section having a tab 2 at one end are shown in FIGS. The anti-slip 3 can be inserted and removed freely. Note that the grip portion 2 is preferably formed with a slightly wider width so as not to be pulled out into the holder.

The present invention provides the above-mentioned anti-slip device by embedding it in the tire at a predetermined interval so that the upper part of the anti-slip 3 appropriately protrudes from the ground contact surface of the tire 4, and both ends of the anti-slip do not protrude from the side surfaces of the tire. It is something to do.

Here, the holder 1 is fixed to the tire, and the anti-slip 3 is
It can be inserted and removed from the side of the tire.

Although the present invention has the above-described configuration, the anti-slip 3 protruding from the ground contact surface of the tire reliably grips the frozen road surface, so it exhibits better braking and climbing performance than chains as well as spikes. .

Furthermore, on roads without snow, it is sufficient to pull out the anti-slip 3 when driving, and unlike spikes, the vehicle does not damage the road or emit noise.

This work of inserting and removing the anti-slip is easier and takes less time than attaching and detaching the chain.

Furthermore, the present invention has the great feature of being able to use cleats of different heights. In other words, for example, if you keep a tall anti-skid in reserve, you can replace it when there is a lot of snow, or when the wheels get stuck in the snow and can't get out, because the protrusion of the anti-skid is large. , is extremely effective.

Next, other embodiments of the present invention will be described.

FIG. 4 is a partially enlarged vertical cross-sectional view showing a second embodiment of the present invention. , a rectangular recessed spring attachment part 6 is provided, and the other end of a leaf spring 8 having a protrusion 7 at one end is attached to the spring attachment part 6.
The protrusion 7 is fixed so as to fit into the hole 5 of the holder 1. Note that the tip of the protrusion 7 is sloped.

This second embodiment was made to prevent the non-slip 3 from coming off naturally from the holder 1. When removing the non-slip, the leaf spring 8 is pushed up in the direction of the arrow shown in the figure, and the protrusion 7 is removed from the hole 5 and pulled out.

Also, when inserting the protrusion 7, the tip of the protrusion 7 is inclined, so if you push the anti-slip all the way in, the protrusion 7 will fit into the hole 5.
You'll get stuck in it.

FIG. 5 shows a third embodiment of the present invention, in which the height is increased, leaf springs 8A are fixed to the four corners of the ceiling, and
The bottom of the holder 1 and the back of the anti-slip 3 are provided with four corrugated parts 9 that engage with each other and a large number of convex parts 10.

Therefore, when you fully insert the anti-slip into the holder,
The concave portion 9 of the holder and the non-slip convex portion 10 are in a state of engagement.

Similar to the second embodiment, this third embodiment prevents the non-slip from coming off naturally from the holder, and also prevents the tire from running onto the sidewalk when an extremely strong lateral force is applied to the non-slip. Because the holder and the numerous recesses and protrusions of the anti-slip mesh with each other,
The anti-slip will not move sideways.

FIG. 6 shows a fourth embodiment of the present invention. In this embodiment, only the bottom portions 11...11A are left at the center of the holder 1 and the anti-slip 3, which are made of elastic metal or synthetic resin, and the opening portions 12 are arranged at appropriate intervals. ...12A is provided.

Therefore, even when the anti-slip member is inserted into the holder, the bottom portions 11...11A are elastic and can be bent at the center.

This fourth embodiment flexibly absorbs large distortions occurring in tires, and is particularly effective for heavy trucks and the like.

Note that the bottom portion 11...IIA may not be formed integrally with the main body, but may be fixed with a plate spring or the like.

FIG. 7 shows a fifth embodiment of the present invention, and as shown in the figure, the cross section of the holder 1 is formed into a convex shape with an open top. This embodiment not only reinforces the holder, but also allows smooth insertion and removal of the anti-slip.

In each of the embodiments, the knob portion 2 is shown as a flat surface, but like the anti-slip portion 3, it may have a convex cross section.

As described above, the present invention provides a completely new type of tire skid device that inserts or removes the skid depending on the road condition, and thus prevents damage to the road. In addition to preventing the resulting dust pollution, it also improves driving performance on frozen roads.
Furthermore, it promises to reduce slip accidents and the like.
