Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a carrier for a parking device such as a one-way elevator type, an elevator slide type, or a flat reciprocating type.

(B) Prior art In the conventional parking device, methods for transferring the car from the stopping position to the carrier and from the carrier to the storage position include a fork type in which the car is transferred by a fork, a roller conveyor type in which the car is transferred by rollers, and a car. There is a wheel-carrying type, in which the brake-side wheel of the front or rear wheel is lifted up and moved, and the other wheel is rotated and transferred while remaining on the ground.

(C) Problems to be Solved by the Invention In the fork type and roller conveyor type transfer methods, each storage room must be equipped with a fork or roller conveyor, and the vehicle stopping position must also be equipped with a fork or roller conveyor. Otherwise, the cost will be very high because the driver will have to drive himself into the 1V container, and if he drives into the 1V container by himself, he will have to drive into the 1V container by himself. It had disadvantages such as having to make it large and being dangerous. In addition, with the wheel-holding type, only the wheel on the braking side is lifted up while the other wheels are kept on the ground, so if the direction of the wheel is the same as the direction of transport, there is no problem, but the handle If the cutting conditions of the vehicle do not match, or if the wheels are controlled, the vehicle will be dragged and transported, which will not only make the transportation not smooth, but also damage the vehicle. There were drawbacks such as the need to select the holding wheels depending on the drive type or vehicle type.

(d) Means for Solving the Problems In order to improve the above-mentioned drawbacks, the present invention has a width equal to or greater than the width of an automobile wheel, at least the tip of which is constructed of a small-diameter roller or an endless band conhair with a low vertical height. Place the container with the front and rear wheels of the car on the car mounting stand.
The length is longer than A, and the two sides are arranged in parallel according to the dimensions of the car track, and a drive device is provided to drive each conhair in the same direction in the forward and reverse directions, and the car mounting base is extended and retracted to the stopper body. It is characterized in that it can be freely installed, the conveying direction of the conveyor and the extending/contracting direction of the car mounting platform are curved in one direction, and the conveying speed of the conveyor and the extending/contracting speed of the automobile mounting platform are configured to be the same. .

(e) Effect 11! ! In the case of transferring a car outside the container to the general container, first, we will explain the effect when there is a braked wheel in front of the primary container and an unbraked wheel behind it. Rotate the side conhairs toward the front as seen from the carrier, extend the car mounting stand on the main body of the vehicle, and move it forward. IJ'! When the iF conveyor enters the ground contact area of the wheel, the tire of the wheel has elasticity,
Since the thickness of the straight line of rollers or the endless belt conveyor is extremely small compared to that of the wheels, it slips between the wheels and gets wedged between the wheels and the ground surface. In this case, the tires of the wheels are deformed by the weight of the car and have a contact length of about 10 to 15 cm when viewed from the axle axis direction, so the conveyor enters as shown in Figure 7. However, the rest of the contact area is in contact with the ground, and there is a frictional force in the direction of pulling the wheels in at the contact area with the conveyor, so the car is moving forward. L will never be released.

Due to the approach of the conhair, the friction force between the wheels and the conhair becomes greater than that of the ground contact part, and as the car platform advances, the wheels ride onto the conveyor, and as the conhair moves, they are sequentially moved to the back of the conhair. However, since the transfer speed of the conhair and the advancing speed of the car platform are the same, the unbraked wheels at the rear remain in their original position, and are eventually scooped up by the conhair at the tip. Completely housed on the Conhair. Then, when the drive of the conveyor is stopped and the car platform is retracted and moved backward, the car is transferred into the carrier. Next, contrary to the above, if there is an unbraked wheel on the front side of the carrier and a braked wheel behind it, the rear wheel remains on the ground while being moved, so the car loading platform can move forward. The wheels on the near side ride onto the conveyor, and as the car platform advances, the wheels move deeper into the conveyor, but the transport speed of the conveyor and the traveling speed of the car platform are the same, and the directions are opposite. Therefore, the wheel does not rotate and remains as it is, but it is guided by the conveyor and enters without resistance.Soon, the braked wheel is scooped up and placed on the conveyor as in the previous case. fully contained,
The car platform retracts and moves back, and the car is transferred into the carrier.

Next, to explain the operation when transferring a car inside the carrier to the outside of the carrier, the car mounting platform on the carrier body is extended and entered into the storage chamber, and then the two side container hairs are rotated to the transfer side. When the car platform is retracted and moved backward while moving the vehicle, the transfer speed of the conveyor and the backward speed of the car platform are the same and the directions are opposite.
The car remains in its position relative to the storage room,
The car platform comes off and the car lands.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. In FIGS. 2 and 3, 1 is a general container main body, 2 is an intermediate body, and 3 is a car mounting stand. The guide rollers 6 provided on the intermediate body 2 are secured to the guide rails 7 of the vehicle mounting base 3, and are movable only in the left and right directions. Reference numeral 8 denotes two pinions arranged in parallel that are supported and driven by the carrier main body 1 (the driving device is not shown), and are meshed with a rack 9 provided on the lower surface of the intermediate body 2.

10 is Che 7, and one end is 11! ! 18 after being fixed to the right side of the main body 1 in the drawing and stretched to the sprocket 11 rotatably supported on the left side of the intermediate body 2.
0" direction, and the other end is fixed to the right side of the car loading table 3. 12 is also a check 7, and symmetrically to the above, its -αfil is fixed to the left side of the carrier body 1. , the sprocket is rotatably supported on the right side of the intermediate body 2] 3, the direction is changed by 180°, and the end is fixed to the left side of the car mounting table 3. Next, in FIG. 1, the car mounting table 3 is equipped with a conhair 15 in which a large number of small-diameter rollers 14 having a width twice as wide as the car's wheels are arranged side by side with a length longer than the distance between the front and rear wheels of the car. As shown in Figs. 4 to 6, the conveyor 15 has a roller with a particularly small diameter pointing slightly downward at the tip, and a roller with a relatively larger diameter at the middle. Each roller 14, 14,... has gears 16, 16' and 17, respectively, on both sides of the roller shaft.
The gears 16 and 16' and the gears 17 and 17' are in mesh with each other, and the gears 16 and 17 are fixed to the roller shaft, and the gears 16' and 17' are loosely fitted to the roller shaft.
6 and 17 are driven by a deceleration brake motor 18. The intermediate roller 14 is provided with sprockets 19 and 20 on both sides of the roller shaft, respectively, so that the deceleration brake motor can be driven in one day. 21 is a tension sprocket.

Note that the circumferential speed of each roller 14 and the expansion/contraction speed of the vehicle mounting base 3 are set to be the same.

Next, to explain the operation, when the pinion 8 is driven and rotated counterclockwise (in the top direction) in FIG. Move to the left (toward the sky). In this case, since both ends of the check 710 are fixed to the carrier main body 1 and the car platform 3, and the middle portion thereof is engaged with the sprocket 11 of the intermediate body 2, the movement of the intermediate body 2 to the left is prevented. Accordingly, sprocket I is in the counterclockwise direction (upward direction)
The fixed end of the check 710, that is, the car mounting base 3, is pulled and moved to the left (towards the top) along the guide rollers 6. When pulling in, the pinion 8 may be rotated in the opposite direction. The action of extending the car platform 3 to pull the car onto the conveyor 15 and the effect of transferring the car inside the carrier to the outside of the carrier are as described above.

Note that the conveyor in the above embodiment uses rollers, with a small-diameter roller conveyor at the tip and a relatively large roller conveyor at the middle, but the conveyor at the middle only transports the drawn wheels. Therefore, other conveyors such as a belt or a conveyor belt may be used. In addition, instead of the small diameter roller at the tip of the above embodiment, it is also possible to use a small heald such as a pulley or sprocket, or an endless belt conveyor such as a chain 7, which has a low vertical height, and both have the same effect. It is effective.

(G) Effects of the Invention As described above, the present invention is equipped with a vehicle transfer device on the carrier of the parking device, so there is no need for space for the driver to enter and exit, and the carrier can be made smaller. It is extremely safe for transport, and since the tip of a small i-line roller or a low endless belt conveyor is inserted between the wheel tire and the ground surface, the storage room is not equipped with any equipment. Front-wheel drive, without the need or strain on the car
It can be easily transported regardless of rear-wheel drive, has a simple structure, and can be manufactured at low cost.
