And the in-vehicle surface of the lower casing fork 23 matches. At this time, the vehicle A is placed on both the lower lifter fork 11 and the lower fork 23. When the lower lifter elevating frame 9 is further lowered, the lower lifter fork 11 is moved to the lower casing fork 2.
Passing by 3, the vehicle remains on the lower cabin fork 23.
On the other hand, the lower lifter elevating frame 9 continues to descend, reaches the lower limit position and stops. The arrangement at this time is shown in FIG. At this time, the lower lifter fork 11 is stored in the elevating frame 9 (base) by the retreat mechanism, and is in the state of FIG. If the lower lifter elevating frame 9 moves up in this state, as shown in FIG. 13E, the lifter 9 can move up without interference with the vehicle on the lower cabin fork 23, and the vehicle can be transferred.

On the other hand, the structure of the upper casing 2 for housing the vehicle will be described with reference to FIGS.

A lock device 32 is provided on the vehicle compartment frame 25 at the center of the upper casing 2 in the short side direction. The lock device 3
Reference numeral 2 denotes a device for moving the pin 49 in and out by a method such as a combination of a pneumatic or hydraulic cylinder, a solenoid, a screw and a motor. The pin 49 restrains the swing of the swing arm 30 and fixes the entire opening / closing frame 27.

As shown in FIG. 15, when the lock device 32 is released, the opening / closing frame 27 is opened downward by gravity with its rotation shaft 28 as the center of rotation, and the shock absorber 45 provided in the vehicle interior frame 25 and the swing arm 30 collide. By doing
Stop hanging. A shock absorber 45, which is an elastic body such as rubber or a shock absorber using air pressure or oil pressure, also serves as a rotation stopper of the swing arm 30 and a fork 26.
Prevents bouncing in the event of a collision. In this state, the fork 26 hangs out of the range in which the upper lifter 7 can move up and down, so that the upper lifter 7 on which the vehicle is mounted can move up and down.

When the vehicle on the upper lifter fork 21 is transferred onto the upper casing fork 26, the upper lifter 7 starts to rise with the fork 26 and the swing arm 30 hanging down. At a certain elevation, as shown in FIG. 16, the guide 3 provided at the end of the upper lifter turning frame 18
The roller 3 and the roller 31 attached to the tip of the swing arm 30 come into contact with each other. When the upper lifter 7 continues to move up, the roller 32 in contact with it moves along the guide 33, and the swing arm 30 and the fork 26 are in a horizontal state, that is, in a closed state. In this state, the upper lifter 7 stops rising, and the pin 49 of the lock device 32 projects to restrain the swing arm 30 and fix the opening / closing frame 27 and the fork 26. Subsequently, when the upper lifter 7 starts lowering, the upper lifter fork 21 passes by the upper casing fork 26 fixed in a closed state, and the vehicle is transferred at this time.

In this embodiment, the fork 26 is opened and closed by using the gravity and the rising operation of the upper lifter 7 to open and close the opening and closing frame 27. The frame 27 may be opened and closed.

As with the retracting mechanism of the lower lifter fork 11, a method of storing only the fork 26 in the opening / closing frame 27 (base) in the horizontal direction, and retracting the fork 26 having the slide mechanism to the adjacent upper casing. It is also possible to adopt a structure in which a traversing device is provided on each of the opening / closing frames 27 in which the rotating shaft is omitted, and the dimension of the upper casing in the short side direction is made variable, and the forks are retracted.

In short, if a device for temporarily avoiding interference between the upper casing fork 26 and the vehicle on the upper lifter 7 that rises is provided in the upper casing 2, the vehicle of the upper lifter 7 is transferred to the upper casing 2. It becomes possible.

In this embodiment, when the vehicle entrance floor is set on the ground in order to install the vehicle in the basement space of the building, as shown in FIG. A lifter 35 and an entrance / exit room 34 are separately provided in consideration of the safety of the user when entering / exiting the entrance / exit.

FIG. 17 shows the structure of the loading / unloading lifter 35.
It consists of a pantograph type lifting frame 36 suspended from the ceiling of the underground space and a loading frame 37 on which a vehicle is mounted. The in-vehicle unit on which the vehicle is mounted is a loading frame 3
7 (base) and a fork 38 protruding in the horizontal direction of the loading frame 37 (base).
The fork 38 is installed in a shape that allows the fork 38 to pass up and down with respect to the upper lifter fork 21, and has a retraction mechanism having a hanging structure similar to the upper casing fork 26 and the opening and closing frame 27. Also, the loading frame 37
By a pair of lifting frames 36 fixed to both ends, the frame reciprocates up and down between the vehicle entry floor 38 and the upper fork height.

When the loading frame 37 is stopped on the same plane as the floor on which the vehicle is loaded, portions other than the frame and the forks are open. Therefore, the movable floor 40 provided with a separate opening / closing device is provided to reduce the floor surface. Formed to allow entry of the vehicle.

The structure of the movable floor 40 will be described with reference to FIG. The movable floor 40 that forms a floor surface that does not interfere with the loading frame 37 on the vehicle entry floor 39 is connected to bearings 41 in which a plurality of rotating shafts 42 fixed to the movable floor 40 are installed on both sides of the opening of the vehicle entry floor 39. While rotatably supported,
A swing arm 43 fixed to an arbitrary position of the rotating shaft 42 is swung by expansion and contraction of a cylinder 44 to open and close the movable floor 40. The movable floor 40 in the open state is a warehouse lifter 34.
Is stopped out of the range of elevation of the entry / exit lifter 34 so as not to hinder the elevation of the elevator. Although the movable floor 40 is a double-opening type, the movable floor is constituted by one surface, and there is no problem even if the floor surface is moved by sliding and lifting.

As described above, when the loading / unloading lifter 34 and the movable floor 40 are provided, the vehicle on the loading floor 39 is transferred to the traveling vehicle 4 and then, without waiting for the completion of the storage of the traveling vehicle, the entering floor is re-established. In this case, a state in which the vehicle can enter the vehicle can be formed, so that even if there is a continuous vehicle, the next vehicle can enter the vehicle. That is, since the vehicle conveyance from the entrance / exit room to the traveling vehicle and the vehicle transportation from the traveling vehicle to each of the vehicle compartments can operate independently and in an overlapping manner, there is an advantage that the time required for continuous entrance / exit can be reduced.

Next, the operation of the above embodiment will be described.

At this time, the comb-shaped fork 26 provided with the retracting mechanism of the upper casing 2 is set in an open state, that is, a hanging state in advance. The upper lifter 7 on the traveling vehicle that has arrived immediately below the upper casing is raised, and while closing the upper casing fork 26, the upper lifter fork 21 reaches the upper casing position and stops. After the upper casing fork 26 is fixed by the lock device 30 and the upper lifter 7 is lowered again, the vehicle is transferred from the upper lifter fork 21 to the upper casing fork 26, and the storage is completed.

On the other hand, when the vehicle on the upper lifter 7 is to be stored in the intended lower cab 3, the transport is performed according to the following procedure.

The upper lifter 7 mounted on the vehicle at a height that can be transported in the horizontal direction simultaneously moves the traveling vehicle 4, traverses the upper lifter 7 and the lower lifter 8 connected to each other, and turns the upper lifter 7 simultaneously. , Heading directly below the upper cabin 2 of the destination. At this time, when the turning of the upper lifter 7 is completed, the vehicle is transferred from the upper lifter 7 to the lower lifter 8 as described above, and a state in which the lower lifter 8 can move up and down is formed.

When the traveling bogie 4 arrives just above the intended lower cabin, the lower lifter 8 starts descending, and the vehicle on the lower lifter fork 11 is moved onto the lower cabin fork 23 by the above-described vehicle transfer procedure. At the same time, the lower lifter fork 11 provided with the evacuation mechanism is stored, rises while avoiding interference with the vehicle in the lower passenger compartment, and the storage is completed.

After the upper carriage 7 and the lower lifter 8 have returned to the same position in the traversing direction, the traveling carriage 4 that has completed the storage stops at an arbitrary position and enters a standby state, or starts operation to store the next vehicle. I do. In addition, when leaving the warehouse, the procedure is the reverse of the above-described case of entering each warehouse.

In this embodiment, a single entry / exit lifter is used. However, a plurality of entry / exit lifters may be installed at any position. Frequently repeated situations can be handled. In this case, the turning mechanism of the upper-stage lifter can be omitted depending on the vehicle directions of entry and exit.

In some cases, a vehicle entry floor may be installed underground by providing another vehicle introduction path, so that the entry / exit lifter can be omitted and the vehicle can be directly entered into the upper lifter on the traveling vehicle.

As described above, the multi-story parking lot apparatus of the present invention is not limited to the above embodiment,
Depending on the number and the layout, design changes such as omission of functions can be appropriately performed without departing from the gist of the present invention.

Further, it is also possible to arrange the multi-story parking lot device according to the present embodiment in a stacked arrangement or a parallel arrangement in an underground space. In the case of the stacked arrangement, a relay lifter having the same function as the entry / exit lifter is separately installed between the parking devices. In the case of the parallel arrangement, if a device for transferring vehicles between the traveling vehicles of the adjacent parking devices is separately provided, the entrance / exit of all the parking devices can be covered by a single entrance / exit lifter.

The multi-story parking lot device according to the present invention can be applied not only to an underground space, but also to a semi-underground space in which a traveling path of a traveling bogie is set at the ground level and the lower cab is accommodated in an underground portion. In addition, it is possible to effectively arrange the cabin in a ground space surrounded by columns and beams, such as a space under an elevated road or a railway.
