Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) Conventionally, it is well known to use a tire chain as an IJ slip stopper device for driving an axle on a snowy or frozen road.

However, tire chain devices require special technical training to install, and require a lot of time and effort even for experienced workers, and if there is wear and tear while driving, it is only a partial breakage of the chain. In both cases, a drawback has been pointed out that in many cases, all one link becomes unusable, and this is a matter of concern to those skilled in the art. The present invention was invented for the purpose of eliminating such drawbacks of tire chains. (Structure of the Invention) A curved portion 3' that includes the J-shaped anti-slip fitting 3 and the tire 6.
and a straight shaft portion 3'', and the tire 6 is formed at the curved portion 3'.
, and the straight shaft part 3'' is connected to the arm 1 with both the inner and outer rings 1'.
The ring 1'. It is attached to a sliding pipe 2 with several thin tubes inserted radially from the center of the lr, and a ratchet gear type rack 8 is carved outward on the linear shaft portion 3'', and the sliding pipe on the outer ring 1'' side A lever 4 is built into the sliding tube 2 so that it can be fired by the ammunition 5 packed in bales at 2, and the lever claw 9 is made to mesh with the rack 8. An anti-slip device attached to a tire, characterized in that it can be supported by a shaft portion 3''.

(Embodiment of the Invention) As shown in FIGS. 1 to 4, the present invention comprises a J-shaped anti-slip fitting 3 consisting of a curved portion 3' that encompasses the tire 6, and a straight shaft portion 3''. The curved portion 3' encompasses the tire 6, and the linear shaft portion 3'' is formed into both inner and outer rings 1' concentric with the tire 6. 1" is connected to an arm connected by several ribs 1'", and a sliding tube 2 extending radially from the center of the ring 1'.1" is attached to the arm. has a ratchet gear type rack 8 carved outward, and the outer ring 1''
A lever 4 is built into the firing pipe 2 so that it can be fired by the ammunition 5 mounted on the sliding pipe 2 on the side, and the lever claw part 9 is made to mesh with the rack 8, thereby providing partial resistance when driving the wheels. This relates to an anti-slip device for mounting on a tire, which is characterized in that it can be supported by this single straight shaft portion 3''.

In the present invention, the anti-slip fitting 3 is "both inner and outer rings".1
'' was connected radially with several ribs at equal intervals to the sliding pipe 2, which was made of iron. My goal is"
When the specific anti-slip metal fittings 3 are in contact with the ground at every corner, and the resistance is applied to the arm 1', the other anti-slip metal fittings 3 are entwined around the circumference of the tire 6 and hold the central arm kuru. So,
Even though there is no need to fix the arm guard in a special way, the same thing can be done for the non-slip fitting 3 at the same time.

As a result, a specific part of the tire 6 that is in contact with the ground at a specific time during rotation adapts to the weight of the fighter and distorts the annular circumferential surface. In the case of this partial deformation, expansion and contraction movements are possible between the arm turtle and the sliding tube 2, thereby absorbing and buffering the vibrations caused by the torque adjustment. In addition, in the present invention, mechanisms such as the arm turtle, the tension pipe 2, and the anti-slip metal fitting 3 can be attached to one side of the foil T, so that complicated labor can be omitted and the anti-slip metal fitting 3, which is subject to severe wear, can be installed. This part also has the great effect of being easily removable and replaceable at any time.As shown in Figure 1, the anti-slip fitting 3 entwined around the circumference of the tire is a counterfeit fitting built into the arm turtle. The tube 2 maintains the distribution of the circumference of the tire 6, and there is no risk of impeding the rotational power.The bullet 5 attached to the sliding tube 2 and the lever fish that presses the bullet shaft provide a non-slip fitting. 3. Automatically stabilizes the sitting position.

This structure is as shown in Figure 2 and Figure 2.
The lever crab can be easily inserted into the sliding pipe 2 using the ratchet type rack 8 attached to the long ratchet side of the non-slip fitting 3. When the foil 7 is bitten, it always bites in due to the tension of the elastic movement.Therefore, even when the foil 7 reaches high speed rotation and the anti-slip fitting 3 becomes easy to pull out due to centrifugal force, etc., it will never come out. It was devised in such a way. The part of the anti-slip fitting 3 that touches the ground has a mottled uneven pattern to make it difficult to slip against snow and ice. ``This structure also prevents skidding.

Furthermore, in order to increase the contact area of the anti-slip fitting 3 on the circumference of the tire 6, the number of anti-slip fittings 3 shown in the wing diagram is divided into 6 equal parts and divided into 8 equal parts. As shown in FIG. When carried out as shown in the drawings, the anti-slip metal fittings 3 that contact the ground will also deform due to the local deformation of the tires 6 caused by the weight of the car copper.
As a result, the shaft portion is inserted into the sliding tube 2 by the amount of deformation, and at the same time, the lever claw portion 9, which is set on the sliding tube 21, is bitten into the new rack by the amount of deformation due to the above-mentioned action.

``Even as the tire 6 deforms as it reaches the ground contact surface, the anti-slip fitting 3 absorbed by the sliding pipe 2 will then tighten the sliding pipe 2 toward the center 0 part of the arm when it is released from the ground contact surface. The tension of the rockfish 5 is overcome by the restoring force of the deformed titan 8, and at the same time, the anti-slip fitting 3 and the sliding tube 2, which are fixed by the lever claw part 9 and are integrated, become displaced from the arm bone. (No. (See Figure 3) This state is the beginning of the expansion and contraction movement. When the tire 6 is in a deformed state, the bullet 5 is fully extended. When the tire 8 returns to its normal shape, the bullet 6 is compressed. As mentioned above, the degree of expansion and contraction differs depending on the degree of deformation of the tire 6, and is considerably influenced by the strength of the tire air pressure.

This expansion/contraction movement is constantly repeated while the car is running, thereby softening vibrations to the car body and ensuring adhesion and flexibility to the tire SI.Finally, regarding attachment and detachment of the device of the present invention. The explanation is as follows: First, move the arm 1 to the center of the base of the wheel 7, and insert the linear shaft portion 3'' into each sliding tube 2 while entangling the anti-slip fitting 3 around the tire 6. At this time, the lever claw part ball set in the sliding tube 2 is pushed by the bullet 5 and engages the rack 8 part, thereby completing the operation. Conversely, when removing this device from the tire 6, press the lever 4 set on the sliding tube 2 in the direction of the tire 6. The metal fittings 3 can be easily removed and removed.

In this way, the present invention has a chopstick effect that has not been found in conventional known examples in that it can be operated on one side of the wheel 7 for both installation and removal.
