When the lift chain 26 is sent in one direction or the other direction by the drive of the lifting motor 23, the front end of the lifting lift 17 is going to be positively raised or lowered. The rear end of the elevating lift 17 is moved up and down through the guide sprocket 21A, the balance chain 20, and the guide sprocket 21B in conjunction with the elevating operation on the front end side. Therefore, as shown by a two-dot chain line in FIG. 5, the lift 17 is guided by the lift frames 12A to 12D and moved up and down in the lift space S while maintaining a substantially horizontal state.

Next, the operation of the multi-story parking device having the above configuration will be described. (Storing Operation) In order to store the car C in the multi-story parking device, the lift 17 is moved and arranged below the floor 32. In this state, the vehicle C enters the loading / unloading room F and stops on the floor 32. And the lifting lift 17
Is lifted, the fork 19 of the lift 17 and the fork of the floor 32 pass each other, and the vehicle C on the floor 32 is delivered to the lift 17.

The lift 17 carrying the car C is lifted in the lift space S and stopped at a position above the floor to which the predetermined storage room K1 belongs. Thereafter, the traversing trays 28A and 28B in the storage room K1 are traversed to the elevating space S. In this state, when the lift 17 is lowered, the fork 19 of the lift 17 and the traversing trays 28A, 2
The car C is passed from the lifting lift 17 to the traversing trays 28A and 28B. Traversing trays 28A and 28B that have received car C
Is traversed in the storage room K1, and the car C is stored in the predetermined storage room K1.

(Exiting Operation) In order to take out the car C from the multi-story parking device, the storage room K in which the car C is stored is stored.
The first traversing tray 28A, 28B is traversed to the elevating space S. By raising the lift 17 in this state, the fork 19 of the lift 17 and the fork 31 of the traversing trays 28A, 28B pass each other, and the vehicle C is received from the traversing trays 28A, 28B to the lift 17. Passed.

The lift 17 carrying the car C is temporarily stopped at a position above the floor of the storage room K1, and the traversing trays 28A, 28B located in the lift space S during that time.
Is traversed to its own storage room K1. Then, the lift 17 is lowered to the lowest floor, the fork 19 of the lift 17 and the fork of the floor 32 pass each other, and the automobile C is delivered from the lift 17 to the floor 32. Then, when the car C is put out of the entry / exit room F, the exit is completed.

The present embodiment having the above configuration has the following effects. (1) Only the front end of the lift frame 18 of the lift 17 is supported by the lift chain 26, and the guide sprockets 21A and 21B and the balance chain 2
With the linkage of 0, the lift frame 18 is held in a substantially horizontal state. In order to raise and lower the lift frame 18, it is only necessary to wind and unwind the lift chain 26. Therefore, the elevating motor 23 can be arranged on the side of the elevating space S, and the elevating motor 23 and the lift chain 2 can be arranged.
Even if 6th etc. is arranged at a low position (position that wraps around the space on the top floor), the traversing trays 28A and 28B on the top floor
And the vehicle C on the lift 17 does not interfere. Therefore, the overall height of the multi-story parking device can be reduced as compared with the conventional one. Also, since only the front end side of the lift frame 18 needs to be positively moved up and down, the number of the elevating motors 23 can be reduced as compared with the conventional case, and the elevating mechanism can be configured at low cost.

(2) The two drive sprockets 24 are connected by the counter shaft 22 so that the lifting motor 2
3 are common. Therefore, only one drive source (elevation motor 23) is required to move the elevating lift 17 up and down.
The control circuit is also simplified. As a result, the lifting mechanism can be configured at low cost.

(3) The balance chain 20 is inserted into the inner space of the lift frame 18. Therefore, it is not necessary to secure a space for disposing the balance chain 20 around the lift frame 18, which contributes to space saving of the lifting mechanism.

(4) The forks 19A and 19B are inserted and fixed to the lift frame 18 through the fork insertion holes 18c. Here, in the conventional elevating lift, a plurality of forks are fixed to the mounting plate by welding, and the mounting plate is fixed to the side surface of the lift frame by welding. Therefore, the lift frame supports the fork in a cantilever manner, and when welding the fork and the mounting plate, if the melting is not sufficiently performed, the mounting strength that can withstand the weight of the automobile C cannot be secured. . However, in this embodiment,
The ends of the forks 19A and 19B are welded and fixed to the steel material 18b and the fork receiving member 33, and an intermediate position thereof is supported by the inner edge of the fork insertion hole 18c. Therefore, it is possible to obtain a predetermined mounting strength without having to melt the welded portion so much. In other words, with the same welding method, the fork 19
A, 19B can increase the strength of attachment to the lift frame 18.

(5) The insertion end of the fork 19A (center side) arranged at a different height from the other forks 19A, 19B is fixed to the fork receiving member 33 by welding. Therefore, behind the fork receiving member 33, an insertion space M that is not interfered by the fork 19A (center side) can be secured. As a result, in this embodiment, the balance chain 20 is inserted into the inner space of the lift frame 18 and the forks 19A, 19B are inserted and fixed in the lift frame 18 even if the forks 19A, 19B are arranged at different heights. At the same time.

The present invention can be practiced in the following modes without departing from the spirit of the present invention. (1) Both drive sprockets 24 are rotationally driven by separate lifting motors. By doing so, the countershaft 22 that takes up space can be eliminated.

(2) In the above embodiment, the delivery of the automobile C is performed by the alternately provided forks 19A, 19B, 31. However, the transverse trays 28A, 28
B may be directly placed on the elevating lift 17 and moved between each storage room K1 and the entry / exit room F.

(3) The storage space K is embodied in a multi-story parking device formed only on one side of the lift space S. (4) As a three-dimensional storage tower for storing items other than the automobile C, for example, it is embodied in an automatic warehouse or the like.

The technical ideas that can be grasped from the above embodiment will be described. The first and second rotating bodies 21A, 21
The three-dimensional storage tower according to claim 1, wherein B and the cord-like member 20 are in an engagement relationship.

In this manner, the first and second rotating bodies 2
Engagement between 1A, 21B and the cord-like member 20 is ensured.

[0050]
