DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a plurality of parking shelves vertically in a house, and a pallet on which a vehicle is directly mounted is moved up and down along the parking shelves by an elevator. In a multi-story parking device in which a pallet is horizontally moved and transferred, and a pallet is similarly transferred from a parking shelf to an elevator and lowered, the pallet placed on the parking shelf is prevented from moving due to vibration or the like. The present invention relates to a pallet lock device.

[0002]

2. Description of the Related Art In this type of multi-story parking device, a pallet mounted on an elevator is transferred from the elevator to a parking shelf and from a parking shelf to an elevator by a transfer device provided on the elevator. There is also a roller rail on the parking shelf, which supports the pallet on it, making it easy to slip, and if this is the case, it will be shaken by vibrations such as earthquakes and vibrations generated when driving elevators , Because there is a risk that the pallet will move sideways and come off the parking shelf,
The pallets stored in the parking shelves are immovably locked by a lock device.

[0005] As a conventional locking device for locking, as shown in FIG. 5, a lock lever 24 provided on a parking shelf 3 so as to be swingable up and down is engaged with a side surface of a pallet 5 by a spring 25. Stuff. Alternatively, as shown in FIG. 6, a roller 27 is provided at a lower end of a lock pin 26 which stands up, and a cam 2 having a tip formed on an inclined surface below the roller 27.
8 is provided so as to be able to move horizontally, and the cam 28 is advanced to raise the lock pin 26 and to enter an engagement hole 29 provided on the back surface of the pallet 5.

[0004]

When the lock lever is of the type in which the spring is urged by a spring, the lock lever is disengaged from the pallet when a moving force stronger than the spring force is applied to the pallet because only the spring force is applied. However, the movement is dangerous when a large force due to an unexpected earthquake or the like is applied, and the lock state is not stable and the reliability is poor.

Further, according to the lock pin described above, the stop position of the pallet is accurately maintained so that the projected position of the lock pin and the receiving hole formed in the pallet can be accurately matched. It is necessary to raise the lock pin deeply into the receiving hole of the pallet due to its strength. Therefore, there is a problem that the parking space is narrowed.

An object of the present invention is to solve the above-mentioned problems, and to provide a reliable and strong locking action, which can be easily released.

[0007]

Means for Solving the Problems A solution according to the present invention is provided with a multi-stage parking shelf in the vertical direction, and a pallet on which a vehicle is mounted is moved up and down by an elevator, and the pallet moves horizontally between the elevator and the parking shelf. A lock device for a pallet transferred on a parking shelf, wherein the operating rod can slide on the parking shelf in a direction parallel to the moving direction of the pallet, and the pallet is lifted and lowered by a spring. The lever is biased in the direction of transport toward the side, and the sliding length of the operating rod is controlled by a stopper, and a lock lever arranged in parallel with the operating rod on the parking shelf is attached to the pallet at the end of the elevator side. It has a projection that engages, pivotally supports the other end up and down freely, and connects the operating rod and the lock lever with a link,
With the protrusion of the lock lever engaged with the pallet, the pivot point of the link with the operating rod is provided closer to the elevator side than an imaginary vertical line from the pivot point of the link with the lock lever. And a pressing rod for pressing the operating rod against a spring.

It is preferable that the link is formed to have such a length that the projection of the lock lever engages with the pallet in a state where the link exists on the virtual vertical line.

[0009]

In the lock device according to the present invention, the operating rod is pressed against the elevator by the spring, and the projection of the lock lever is held in the raised state. When a pallet is transferred to an empty parking shelf in this state, the lock lever is tilted and its projection is lowered by moving the pressing rod forward and retreating the operating rod. After the pallet is transferred in this state, the operating rod is moved back by the repulsive force of the spring by retreating the pressing rod, and the projection engages with the pallet. In addition, at this time, since the stop is performed by limiting the distance to return by the stopper, the pivot point of the link with the operating rod is located closer to the elevator side than the virtual vertical line from the pivot point of the link with the lock lever. Therefore, when a strong force that moves toward the elevator is applied to the pallet, the force acts as an operating force on the elevator through the link, but the operating rod slides in that direction with the stopper. Is restricted, the lock lever is kept stationary and the pallet is prevented from laterally moving.

According to the pallet lock device of the multi-story parking device according to the present invention, the operating rod reciprocating in the horizontal direction and the lock lever are connected by the link, but when the operating rod of the link is locked in the locked state. The operating rod is urged by a spring toward the elevator so that the fulcrum can be set in front of an imaginary vertical line from the pivot with the lock lever, that is, closer to the elevator, and the stopper is slid toward the elevator. Because the amount of movement is limited, even if vibration is given to the pallet from the frame and a force to push down the lock lever is applied, the force that raises the lock lever while the pivot point of the link with the operating rod reaches the virtual vertical line As a result, the locking force of the lock lever against the pallet increases, and even if a large horizontal movement force is applied to the pallet, the lock lever fully opposes this and improves safety So that it is able to.

On the other hand, when the lock lever is disengaged from the pallet, the operating rod slides within the range limited by the stopper with the spring. In particular, the length of the link is determined by the state in which the link exists on the virtual vertical line. If the projection of the lock lever is formed so as to securely engage with the pallet, the operating rod is moved back in the actual engaged state even if the pivot point of the link with the operating rod is on the elevator side. The force is sufficient to compress the spring, and the lock by the pressing rod can be easily released.
