JPH03204312A - Retractable device for projecting/retracting spike tire pin during traveling - Google Patents

Abstract

PURPOSE:To simplify projecting or retracting operation by embedding a large number of pin boxes which have been spirally connected to each other with a wire and in each of which a bent pin connected to the wire is housed, in the ground surface of a tire, and by operating the pins via the wire by means of a motor with a driving mechanism which has been arranged in the recessed part of the tire wheel so as to be projected or retracted. CONSTITUTION:A wire-pulling-arm guide shaft 17 is turned in the normal or reverse direction via a gear mechanism by the normal or reverse rotation of a motor 17. Thereby a wire-pulling-arm 15 is moved right and left to pull a wire 4 in the arrow direction or in the reverse direction, so that pins 1 are projected or retracted by the action of pin-guide pieces 3. On the other hand, since the pin-boxes 2 in which these pins 1 and pin-guide pieces 3 are housed are spirally connected by the wire 4, all the pins 1 are linkedly projected or retracted for performing or extinguishing spike function. By this constitution, projecting or retracting operation of pins can be simplified.

Description

[Detailed Description of the Invention] This invention prevents pollution and damage to the road surface by easily extending or retracting spike pins by simply pressing a cordless (wireless) button according to the road surface conditions while driving a car. , and related to a device for spiked tire pins that can appear and disappear while driving to maintain safety. Conventional spiked tires run with their pins exposed regardless of the road surface conditions, so spike pins are not necessary when driving on road surfaces. Because they disturb the asphalt, cause pollution, and destroy the road surface, there are strong opinions to abolish spiked tires and replace them with studless tires. Many people have said that even if a fixed period is set, it won't be very effective depending on the weather in the area, but the general public, drivers, and traffic officials all want this problem to be resolved as soon as possible.

This invention aims to solve these problems, and by installing this tire, the pins can be extended or retracted with a simple operation each time according to the road surface conditions, regardless of the region, location, or weather, eliminating pollution and maintaining safety. is intended to do.

This invention will be explained with reference to the drawings. Figure 3 shows how the guide piece (3) is fixed and sandwiched between pin hooks (2-A) and (2-B) from both sides, and the cover clip (6) is also sandwiched between both ends of the pin box at the same time. This is the pin box (2) in FIG.

The details of B1 pin box (2) are the wires (4) in Figure 6.
) in the direction of the arrow, the pin guide piece (3) also -
Since the pin (1) moves in the direction of the arrow, the pin (1) peeks out from the tire contact surface (7). When the pin (1) comes out,
Even if the tire rotates and the pin box faces the ground and heavy pressure is applied to the pin, the pin protrusion (]-A) will not move against the pin guide piece (
3) The pin that protrudes from the top and acts as a stopper is configured so that it does not retract unless operated.

C1 When the wire (4) in Fig. 7 is pulled in the direction of the opposite arrow, the pin guide piece (3) also moves in the direction of the arrow. ), the pin convex part (1-C) is supported, the -C pin is pulled in, and the pin convex part (1-C) stops at the position where it is removed from the pin guiding piece (3), so the pin (1) is a pin guiding piece. (3) acts as a stopper and the retracted pin will not come out unless operated.

D. Embed the pin box (2) and wire (4) shown in Fig. 8 in a spiral shape in the ground contact surface of the tire, and connect both ends of the wire (4) to the tire wheel (Fig. 9, Fig. 1O, Fig. 12) 13
) is connected to the right and left sides of the wire tensioning arm (15) in the donut-shaped case (14) installed in the recess of the tire.

E. The motor (10) in Figure 9 (brief explanation of the drawing) is powered by pulling the wire (4), and when the motor rotates in the normal direction, pulling the wire on the left in the drawing loosens the wire connected to the right side. ) pulls the right wire in reverse rotation, the left wire becomes loose. Therefore, when the motor (10) rotates forward and reverse, the inside of the pin box embedded in the ground plane on the lower half of the figure, the pin guidance in Figure 6 and Figure 7. As the piece (3) moves to the left or to the right, the pin (1) comes out or retracts.Therefore, the pins around the entire circumference of the tire are moved out or retracted by a plurality of motors.

F. The motor (10) installed inside the donut-shaped case (14) in Fig. 12 and its mechanism are as follows:
The arm guide shaft (17) is rotated by the drive of the motor, and the wire pulling arm (15) is moved by the slide screw.Therefore, the wire pulling arm (15) moves to the left and right in the drawing as the motor rotates forward and reverse. ) alternately.

The donut-shaped case (14) in Figure 10 has internal equipment,
A panoramic view of the case, which is sealed to protect it from water and other foreign objects.
FIG. 11 is a partial sectional view thereof.

The G1 spring (16) can be used even if the tire rotates and the pin passer (8) on the tire contact surface (7) in Figure 7 contacts the ground and is crushed and the pin (1) does not come out. The operation drives the motor (10) to move the wire pulling arm (15) in the direction of pulling the wire (4), thereby compressing the spring (16) and rotating the tire to remove the crushed hole from the ground. When released, the spring (
16) is compressed, and the wire (4) is pulled by the repulsive force, and the pin (1) comes out. Therefore, even if some part of the wire is in contact with the ground and the pin passer is crushed, the other Since the part of the wire is far from the ground, the pin of that part will come out. Therefore, the pins around the entire circumference of the tire will come out and retract after the tire rotates more than once after operation.

H1 Figure 13 shows another embodiment in which the wire (4) is pulled by the drive of a motor, in which an electromagnetic coil (18) is provided with an iron core (19), and a wire pulling arm (15) is attached to the end of the iron core (19). Fix the electromagnetic coil (18)
The iron core (19) is actuated to the left and right in the drawing by sending forward and reverse currents to the wire pulling arm (15).
The left and right wires (4) connected to each other are pulled alternately, causing the pins to come out and retract.

By installing tires configured as above and equipping the driver's cab with a cordless (wireless) transmitter, C
While driving a car, the spike pins can be released or retracted with a simple push of a button, depending on the road surface conditions, so there is no need to worry about sudden changes in the weather or location, and pollution can be prevented. Moreover, it has the great effect of maintaining safety.
