Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a large number of parking shelves in a vertical direction in a house, and a pallet on which a vehicle is directly mounted is lifted and lowered along the parking shelves by an elevator, and an empty parking shelves Prevents movement due to vibration of pallets placed on parking shelves in a multi-level parking system that moves pallets horizontally and transfers them, and similarly transfers pallets from parking shelves to elevators and lowers them. The present invention relates to a pallet lock device.

[0002]

2. Description of the Related Art In this type of multi-level parking apparatus, pallets placed on an elevator are transferred from an elevator to a parking rack and from a parking rack to an elevator by a transfer device provided on the elevator. There is also a roller rail on the parking shelf, and the pallet is supported on it, making it slippery, and if it is left as it is, it may be shaken by an earthquake or vibration generated when driving the elevator. Since there is a risk that the pallet will move laterally and come off the parking rack,
A pallet stored in a parking rack is fixedly locked by a lock device.

As a conventional locking device for locking the lock device, as shown in FIG. 5, a lock lever 24 provided on the parking shelf 3 so as to be vertically swingable is engaged with the side surface of the pallet 5 by a spring 25. Things. Alternatively, as shown in FIG. 6, the cam 2 is provided with a roller 27 at the lower end of an upright lock pin 26, and a tip end portion formed as an inclined surface below the roller 27.
It is known that 8 is provided so as to be horizontally movable, and by moving the cam 28 forward, the lock pin 26 is lifted to enter the engagement hole 29 provided on the back surface of the pallet 5.

[0004]

When the lock lever is of a type that is biased 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 the spring force alone is applied. However, it is dangerous when the moving force is applied with a large force due to an unexpected earthquake, etc., and the lock state is not stable and the certainty is poor.

Further, in the case of using the above-mentioned lock pin, the accuracy is adjusted so that the stop position of the pallet can be accurately held so that the projecting position of the lock pin and the receiving hole provided in the pallet are surely aligned. It is necessary to increase the height of the lock pin because it is necessary to deepen the lock pin deeply into the receiving hole of the pallet for strength. There was a problem that the parking space was narrowed.

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

[0007]

The solution according to the present invention is provided with a multi-tiered parking rack in the vertical direction, the elevator lifts the pallet on which the vehicle is placed, and the pallet moves horizontally between the lift and the parking rack. In a multi-level parking device of the type that is transferred by a type, it is a locking device for a pallet that is transferred onto a parking rack, the operating rod can slide on the parking rack in parallel with the moving direction of the pallet, and the pallet is lifted by a spring The lock lever, which is urged in the direction of transfer to the side, is installed by controlling the sliding length of the operating rod with a stopper, and is arranged in parallel with the operating rod on the parking rack, is attached to the pallet at the end of the elevator. It has a protrusion that engages, the other end is pivotally supported up and down, and the operating rod and the lock lever are linked by a link.
In the state where the protrusion of the lock lever is engaged with the pallet, the pivot of the link with the operating rod is located closer to the elevator than the virtual vertical line of the pivot of the link with the lock lever. In addition, the operating rod is provided with a pressing rod that pushes against the spring.

It is preferable that the link is formed in such a length that the protrusion 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 protrusion of the lock lever is held in a raised state. When the pallet is transferred to the empty parking rack in this state, the pressing lever is moved forward and the operating rod is moved backward, whereby the lock lever is tilted and the protrusion thereof is lowered. After the pallet is transferred in this state, the pressing rod is retracted, whereby the operating rod is returned by the repulsive force of the spring and the protrusion engages with the pallet. Moreover, at this time, the stopper restricts the distance to return to the stop, so that 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 towards the elevator side is applied to the pallet, that force acts as an operating force for the elevator side through the link, but the operating rod slides in that direction by the stopper. Since the lock lever is constrained, the lock lever holds the immobile state and prevents the pallet from moving laterally.
