Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an automatic attachment/detachment device for a non-slip chain for automobile tires.

BACKGROUND ART Conventionally, snow tires and snow tires with spikes have been widely used for driving on icy and snowy roads in regions where heavy snowfall occurs.

In recent years, due to improvements in snow removal equipment, some places have become snow-free, making it possible to drive safely without wearing cleats. Moreover, on snow-free paved roads, the road surface is heavily scraped by spikes, etc., causing dust pollution and becoming an environmental problem, and the driving of such roads is gradually being regulated. In addition, the main roads in the city have heavy traffic even during snowfall, so you can clear the snow and drive freely, but when you enter the back streets, the roads turn into ice and snow.
It is dangerous to drive without anti-skid.

Problems to be Solved by the Invention From the above, there has been a need for an appropriate anti-skid device, and the present invention provides an anti-skid chain that can be attached to a tire by simply operating a button while riding on an icy road. In addition, when the road surface changes to a snow-free paved road, the chain can be removed by the same operation to enable normal driving and safe driving, and the use of non-slip chains is reduced as much as possible. The aim is to dramatically improve mileage and prevent noise and dust pollution.

Means to solve the problem Tires are provided with guide grooves of appropriate depth that cross left and right on the circumferential tread part at required intervals, and the wheels to which these are installed have flexible band gears that correspond to the guide grooves of the tire. It crosses the through hole provided in the wheel disc to the left and right, and is connected to the inner diameter surface of the rim so that it can slide left and right according to the required regulations, and a part of the flexible band gear and the guide groove of the tire are connected. The supporting wire fitted with the support wire is connected in an annular shape and goes around the outer circumferential surface of the tire and rim in a transverse direction, and each flexible band gear is a worm gear on the drive shaft that is supported by a bearing part provided on the wheel. The action of the flexible band gear, which is meshed with the gear and slides as the gear rotates, moves the non-slip chain supported by the support wire between the tread part of the tire and one side part of the tire, thereby attaching the non-slip chain to the tire. This is an automatic attachment/detachment device for anti-slip chains for automobile tires.

Function Since the present invention is configured as described above, the anti-skid chain is stored on the outer surface of the drive wheel, so it can be driven like a normal tire on a paved road, and then when the road surface is icy and snowy. When the situation changes, the anti-skid chain stored on the outside surface can be moved to the tread section with a single button operation inside the vehicle, changing the tire to a complete anti-skid tire. Accordingly, an anti-slip chain is attached to the tread of the tire to ensure safe driving.

Embodiments Hereinafter, the present invention will be explained by way of embodiments and drawings. FIGS. 1, 2, 3, 4 and 5 show a first embodiment, and the tire 1 is The outer periphery of the tread portion 1a is divided into eight equal parts, and eight guide grooves 2, 2... are provided that cross the left and right sides at appropriate depths, and the support wire 3 is inserted into each of the guide grooves 2, 2..., and the supporting wires 3 are inserted at both ends. The extension part is connected to both sides 1b, 1b of the tire 1.
A bearing tube 8 is connected to either end of a flexible band gear 5 which is arranged along the outer circumference of the rim 4 via a spring 6, and is welded to the wheel disc 7 on the inside diameter of the rim 4. A worm gear 9 on a drive shaft 10, which is supported by a shaft, is engaged with the upper surface gear part 5a of the flexible band gear 5, and a pulley 11 is attached to the other end of the drive shaft 10. It moves the band gear 5 back and forth in the transverse direction.

The flexible band gear 5 is a flexible band that functions as a chain with gears attached, and is curved in the radial direction but hardly curved laterally. In order to improve the sliding of the flexible band gear 5 and the support wire 3, resin sheets 12, 12 are wrapped around the inner diameter outer surface of the rim 4 and both side portions 1b, 1b of the tire 1 to a required width.

Connecting rings 13 and 14 are connected to one end portion 3a and intermediate portion 3b of each of the supporting wires 3, and the connecting rings 13 and 14 adjacent to each other in the outer circumferential direction have X
The chain pieces 15a connected to the mold are connected to form the non-slip chain 15 as a whole.

At the center of the wheel disc 7, a cap 18 with a center shaft 17 integrally attached is attached to the outside of the hub hole 16, and the cap 18 covers the bearing tube 20 via bearings 19, 19 fitted to the cap 18. A receiver 22 that supports the support rod 21 slidably back and forth is integrally provided at the end thereof, and a lining 2 that contacts each of the pulleys 11 is provided at the tip of the support rod 21.
3 and 24 are attached to drive plates 25 and 26 in the form of arcuate concave and convex surfaces of a predetermined length with a predetermined distance apart from the rotation path in which each pulley 11 rotates, and are made to correspond to each other. The base end of the support rod 21 is connected to a pole joint 39 supported by the vehicle body 38, and is maintained in its normal position.

When the support rod 21 is moved back and forth, one of the linings 23 and 24 comes into contact with the pulley 11, and each of the linings 23 and 24 rotates once.

As shown in FIG. 4, an embodiment of the mechanism for operating the support rod 21 in response to a command from inside the vehicle has solenoids 27 and 28 supported in the front and back on the lower outer circumference of the receiving tube 22, and the respective plungers 29 , 30 are connected to the anchoring pins 31, 32 provided on the side of the support rod 21, and the support rod 21 is connected by the operation of the plunger 29 or 30.
It moves forward or backward.

The receiving tube 22 has an arm 35 standing on the upper surface of the receiving tube 22 and an arm 3 on the support rod 21 on its outer circumferential upper surface.
Center return springs 33 and 34 are tensioned so as to be pulled between the solenoids 27 and 37, and when the solenoids 27 and 28 do not operate, the support rod 21 is returned to the center, and the lining of the drive plates 25 and 26 is 23 and 24 are prevented from coming into contact with each pulley 11.

As shown in FIG. 5, the solenoids 27 and 28 are installed in a trunk 38a of a vehicle body 38, and when activated, a lever 38b rotates around a shaft support 49 on the vehicle body to move the support rod 21 forward. Alternatively, the driving plates 25 and 26 may be moved backward to approach each pulley and rotate them.

40a is a button for supplying power to the solenoid 27, 40b is a button for supplying power to the solenoid 28, and 40c is a release button. Further, 41 is a passage hole opened in the disk 7, through which the flexible gear 5 is inserted inside and outside.
Similarly, 42 is a guide support frame for the flexible gear 5, 43 is embedded in the tread portion 1a of the tire 1 at a required interval,
The lower surface is a sliding seat plate that appears on the bottom surface of the guide groove 2.

Since the first embodiment of the present invention is configured as described above, when driving on an icy road, the tires serving as driving wheels are replaced with each other, and accessories are installed on the tires and the vehicle body. If you encounter an icy and snowy road surface, press the power supply button 40a to supply power to the solenoid 27, which will activate the support rod 2.
1 to the rear against its balance spring 37. Therefore, the lining 23 of the drive board 25, which was previously mounted on one side portion 1b, is now mounted on the tread portion 1a within the rotation path of each pulley 11. Therefore, as in the embodiment, the release button 40c is pressed and the power supply button 40 is pressed.
a to stop the power supply to the solenoid 27.
Then, the support rod 21 returns the drive plates 25, 26 to the neutral position again by the action of the balance spring.

Since the support wire 24 is continuous with the flexible band gear 5 that meshes with the worm gear 9, it is kept in a moving state, and therefore runs with the chain 15 in an attached state. Since the support wire 3 is fitted into the guide groove 3 of the tread portion 1a, it will not come off, and even if it slides, a synthetic resin plate is placed at the bottom of the groove, so it can operate smoothly and slide. The stop chain 15 allows the shoulder to easily pass over and smoothly moves to the tread portion 1a. In addition, each pulley 11 rotates once for each revolution of the wheel, and the supporting wire 3 moves by the required width each time, so the anti-slip chain 15 also moves little by little, and the tires are not shifted partially. The movement is extremely smooth without any unreasonable tightening action being applied to 1. The non-slip chain 15 provides a reliable grip and the vehicle runs safely.

On snow-covered roads, the anti-skid chain 15 hardly wears and does not damage the road surface.

Next, when the driver reaches a snow-free road surface, when another release button is pressed, power is supplied to the other solenoid 28, and the action of the plunger 30 causes the support rod 21 to slide forward. Therefore, the lining 24 of the drive board 26
comes into contact with each pulley 11 and rotates each pulley 11 in the opposite direction, so that the support wire 3 is returned to its original position and the anti-skid chain 15 is again connected to the tire 1.
to one side portion 1b. Since the anti-skid chain 15 is pulled up to the inner diameter side from the shoulder part, it does not hit the road surface, and since the support wire 3 is in the guide groove 2, it does not come into contact with the road surface and is separated from the tread part 1a. It is stored in one side part, and the rubber tread part 1a contacts the road surface when driving.

Incidentally, since the operation of the flexible band gear 5 is only required by the rotation of the drive shaft 10, it is not limited to the above-mentioned embodiment, and as shown in FIG.
is mounted on the outside of the center of the hub, and the worm gear 4 is attached to this.
6 is attached, and flexible band gears 4 supported by V pulleys 44 and arranged radially are meshed with this gear, and the drive shaft 45 is directly connected to a motor 48 with a reduction gear and is supported by the rotation of this motor 48. The anti-slip chain 15 may be attached to and detached from the tread portion 1a of the tire 1 by sliding the wire.

In order to form the guide grooves 2 on the tread portion 1a of the tire 1, the grooves can be formed as protrusions in the mold for new tires, but for used tires with worn treads due to driving speed on icy and snowy roads, etc. Even recycled materials can be used satisfactorily, and the present invention can be carried out at low cost.

Effects As described above, according to this invention, since the anti-skid chain is stored on the outer surface of the drive wheel, it can be driven like a normal tire on a paved road, and when the road surface changes to an icy road, the inside of the vehicle will be damaged. With a single push of a button, the anti-skid chain stored on the outside surface can be moved to the tread section, turning it into a complete anti-skid tire. It is equipped with a stop chain and can be driven safely.

This anti-skid chain can be stored on the outer surface of the tire when driving on paved roads, allowing normal driving and protecting it from the severe wear caused by driving on paved roads.The anti-skid chain hardly wears out on icy and snowy roads. This increases the mileage and allows long-term use.

Furthermore, since the vehicle does not run on paved roads with anti-skid chains attached, it does not damage the road surface, thereby eliminating dust pollution and environmental problems.
