Abstract

PURPOSE:To facilitate attachment and removal of a slip stopper by forming a plurality of star-like arms pivoted on circular guide fixed to the sides of a wheel and raising up and down the arms by the combination of a drive means and a spring to set a slip member to the operative and inoperative condition. CONSTITUTION:By moving a drive piece 8 toward the outer periphery of a wheel to disengage the drive piece 8 from a pin 7, an arm 2 is pulled by a spring 9 to be set to the raised-up condition so that an outer end pivot 3 is spaced from a tire tread, a notch portion of a slip stopping member 1 is expanded and a tire contacts the ground between the notches. Thus, the slip stopping member 1 does not work. On the contrary by moving the drive piece 8 toward the axle and pushing the pin 7 are expanded the arms 2, 2 so that the slip stopping member contacts closely the tire tread to fulfill the function of stopping slip. Thus, the slip stopping function can be carried out from the interior of a vehicle to facilitate the attachment and removal of the slip stopper.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (Field of Industrial Application) This invention is an invention that can be used as an anti-slip device for preventing the wheels of an automobile from slipping on a snowy road.

(Prior art) A commonly used R-stage to prevent the wheels of a car from slipping on snowy roads is to wrap a tire around the wheel so as to surround the tread of the tire, and to dig the tire into the snow. This is an attempt to prevent slipping.

Spiked tires, which have nails protruding from the tire tread that dig into the snow to prevent slipping, have recently come into widespread use.

(Problem that Hatsu 1 夛 1 attempts to solve) The method of wrapping the chenos around the tire makes it troublesome to attach and remove the chenos. l! II.I lifted the car body and lifted the wheels off the ground to get to Cheno.

Alternatively, move the car a little and put the +lj wheel on the driver's wheel with the driver4 open, and wrap the wheel tightly around the wheel so that the wheel does not come off due to the rotation of the wheel. It requires a lot of effort and time, and since the work is done on the road, there is a high risk of collision with other vehicles and injury.

Also, it is troublesome to put on and take off the chain, so when driving between a main road where snow has been removed and a side road with snow, it is troublesome to put on and take off the chain one by one. 7 will be damaged.

Spiked tires are also troublesome to put on and take off, so they drive on snow-free roads, damaging roads and causing dust pollution.

Structure of the Invention (Means for Solving Problems) In this invention, a circular guide (5) concentric with the axle is fixed to the vehicle body on the side of the wheel, and both ends are sequentially pivoted to form a zigzag shape. The pivot shaft (4) on one side of the zigzag pattern of the plurality of arms (2) is engaged with the circular guide (5), and the spring (9) that pulls the adjacent arms (2) on this side is connected to both arms ( 2), and the other side of the zigzag arm (2) is pivoted to the anti-slip material (1), which is a partially cut-out ring-shaped material facing the tire tread, and protrudes from the side of the arm. Push the installed pin (7) in the direction of the axle and push the arm (
2) An anti-slip device for automobiles that has a drive piece (8) that opens on the side of the wheel, and the slip prevention material can be attached and detached from the wheel by operating the drive piece even when driving in automatic+lj mode. be.

(Function) When the sliding IE filler is not installed, if the drive piece is placed away from the pin, the arm will be pulled by the spring and narrowed, pushing up the sliding IE filler. Since it is separated from the tire, the sliding arm is supported by a circular guide and remains stationary, and only the wheel can rotate.

When installing the anti-slip material, use a hydraulic or manual link mechanism to drive the drive piece toward the wheel and push the arm pin toward the axle. This causes the arm to open against the spring and remove the anti-slip material. is brought into contact with the outer periphery of the tire, and the anti-slip material is rotated together with the wheel due to friction with the tire, thereby preventing the wheel from slipping. The pivot of the arm near the axle engages the circular guide and rotates together with the wheel while moving within the guide.

(Embodiment) Fig. 1 shows the anti-slip device of the present invention installed on a wheel 12.An anti-slip material l has a plurality of arms 2 formed in a zigzag shape with one and both ends pivoted alternately, It is pivotally connected to a pivot 3 at one end of 2. The pivot shaft 4 at the other end of the arm 2 engages with a circular guide 6 via a roller 5, as shown in FIG. The arm 2 has a pin 7 projecting from the side, and a drive piece 8 is installed outside the wheel 12 in the diametrical direction.

The drive piece 8 has an arcuate shape concentric with the axle, and can be reduced in diameter by a hydraulic cylinder or a manual link mechanism (not shown) to push the pin 7 toward the center or move away from the pin 7. The inner end of the arm 2.2 is tensioned by a spring 9 and the circular guide 6 is connected to the backing plate of the brake l.
It is supported and fixed by several brackets (11) fixed to O. The anti-slip material 1 may be a flexible metal plate with protrusions formed thereon, as illustrated in FIG.

A band-shaped rubber plate with nails protruding like a spiked tire can be used. Cut out a part of the sliding top material as shown in Figure 1.

When the anti-slip mechanism is not used, the drive piece 8 is moved toward the outer circumference of the wheel as shown in FIG. 3.The inner end of the arm 2.2 is pulled by the spring 9, so The arm 2.2 is in the upright position, the outer end of the pivot 3 is placed on the tire tread, and the cut-out part of the anti-slip material 1 is widened, allowing the tire to touch the ground from there, so that only the wheel is on the ground. It will be in a rotating state.

To prevent slipping, the drive piece 8 is moved in the lj axis direction. This pushes pin 7, as shown in Figure 1.
The angle of the arm 2.2 pivoted on the outer pivot 3 opens;
The pivot 3 comes into contact with the tread of the tire, and at the same time the cutout part of the anti-slip material becomes narrower. The cutout portion does not have to be completely closed. Therefore, the anti-slip material 1 rotates together with the tire due to frictional force, and the anti-slip material is interposed between the tread surface and the tire to prevent slipping.

C. Effects of the Invention (1) By operating the drive piece 8 from inside the vehicle while the vehicle is running, the anti-slip material can be quickly attached to and detached from the wheel.

(2) There is no need to go outside the ijf to do the work, so there is no hassle or danger.

(3) Since the anti-slip material can be quickly attached and detached depending on the presence or absence of snow, it does not damage the road or cause dust pollution.
