The effect will be explained below.

Now, in the initial state of the parking facility, the door 3a is closed, the entrance/exit 3 is closed, and the cage 4 has stopped circulating. In addition, the front and rear trucks 13, 13', the elevating frame 22, the transfer device 41, and the moving deck 17 are moved to the right end of the rear truck 13' in FIG. 3 by shortening the plungers 21a, 21'a of the power cylinders 21, 21'. It is waiting in the right row position indicated by the two-dot chain line. Furthermore, the lifting frame 22 and the transfer device 41 are in the lowered position. Note that the desired vehicle W to be taken out from the warehouse is placed on the fixed platform 6 in front of the mobile platform 7, and another vehicle is on the mobile platform 7.
Suppose that W′ is listed. Then, the unloading operation is performed in the following sequence.

(1) First, on a control panel (not shown) provided outside the entrance/exit 3, press a "push button lamp" (not shown) corresponding to the number of the desired cage 4. As a result, the group of cages 4 moves in circulation, and the desired cage 4 reaches a predetermined entry location facing the entry/exit port 3 and stops.

(2) The front and rear bogies 13, 13', etc. move to the right. That is,
Plunger 21 of power cylinder 21, 21'
a, 21'a The front and rear bogies 13,
13', the elevating frame 22, the transfer device 41, the movable deck 17, etc. moved to the right as a unit, and the cage position detector 40 detected the cage 4 by the engagement of the contact 40a with the right side edge of the fixed platform 6. By the way, the above-mentioned rightward movement is stopped (the state indicated by the solid line in Figures 1, 2, and 3).

(3) The two cage fixing devices 36 operate. That is, as the rods 37a of the air cylinder 37 are extended, each holding member 38 is raised and fitted into the positioning hole member 39, thereby fixing the cage 4 as a whole.

(4) The lifting devices 24, 24' operate. By shortening the plunger 32a of each power cylinder 32, the elevating frame 22 and the transfer device 41 are raised integrally via the elevating chains 30, 31 and the like. Near the end of this upward movement, first the transfer claw 5
The U-shaped engaging portion 50a of No. 0 and the engaged piece 51 are loosely engaged, and at the same time, each support roller 34 passes through the notch and hole of the fixed vehicle platform 6 and rises to the recess of the guide rail 35. The mobile platform 7 and the vehicle W' are then lifted upward by continuing the upward movement, and eventually the positioning pin 9 and the positioning hole 6a are disengaged, and the lower edge of the inclined carriageway 7a, 7b The above-mentioned raising operation stops when the fixed vehicle platform 6 is located above the upper surface of the fixed vehicle platform 6. The mobile platform 7 is now the fixed platform 6.
This means that it has completely separated upward from (the state shown by the solid line in Figure 5).

(5) The transfer device 41 is activated. Driven by the reversible motor 46, the endless chain 45 circulates counterclockwise in FIG. 5, and the transfer claw 50 moves the movable platform 7 and the vehicle W' to the left.
During this movement, the mobile platform 7
4 and transfers to the support roller 52 on the ground floor 11. Then, when the right side edge of the movable loading platform 7 is slightly separated to the left from the left edge of the fixed loading platform 6, the above-mentioned transfer operation is completed, and the evacuation operation of the vehicle W' is completed (the state indicated by the two-dot chain line in Fig. 5). .

(6) By driving the power cylinders 21 and 21' in reverse, the elevating frame 22 and the like are lowered to a position where the support roller 34 is sunk into the fixed vehicle platform 6.

(7) Door 3a opens. The driver enters the building 1 through the entrance/exit 3, passes through the movable deck 17, enters the desired vehicle W from the ground floor 11 on the front right side, drives backward on the fixed vehicle platform 6, and returns to the entrance/exit 3. The user evacuates to the outside, and the door 3a closes immediately.

(8) Return the elevating frame 22, etc. to the original elevated position.

(9) Thereafter, by the reverse sequence of operations, the mobile platform 7 and the vehicle W', which had been evacuated to the left, return to their original positions. That is, due to the reverse rotation of the reversible motor 46, the movable carriage 7 and the like move to the right and are positioned directly above the fixed carriage 6, returning to the state shown by the solid line in FIG.
Next, the plunger 32a of the power cylinder 32
The elevating frame 22 and the transfer device 41 are lowered by the extension operation, and the movable platform 7 has the positioning pin 9 fitted into the positioning hole 6a and the contact plate 8
comes into contact with the upper surface of the fixed vehicle platform 6 and is again placed on the fixed vehicle platform 6 in a positioned state. Further, the transfer claw 50 also separates downward from the engaged piece 51. Next, the entire cage 4 is released by deactivating the cage fixing device 36. Finally, the plungers 21a, 2 of the power cylinders 21, 21'
The front and rear bogies 13,1 are shortened by the shortening operation of 1'a.
3' etc. are returned to their original rightward positions.

The above has explained the unloading operation when another vehicle W' is mounted on the mobile undercarriage 7, but the unloading operation when the desired vehicle is the vehicle W' on the mobile undercarriage 7 and the unloading operation when the mobile undercarriage 7 is loaded with another vehicle W' are explained. When the vehicle W enters and leaves the warehouse when the vehicle 7 is empty, there is no need to operate the elevating and retracting device 12 at all, and the operation can be performed only by opening and closing the door 3a. For example, if the mobile platform 7 is empty,
When the vehicle W mounted on the fixed vehicle platform 6 in front of the vehicle W is to be taken out of the garage, the vehicle W may be driven backwards over the movable vehicle platform 7 via the inclined lanes 7a and 7b.

As detailed above, when using the parking facility of the present invention, an elevating and retracting device consisting of a trolley, an elevating frame, a transfer device, etc. is provided below the vehicle entry area near the entrance and exit, and the vehicle mounted on the movable platform is The elevating and retracting device is activated only when the vehicle becomes a hindrance to entering and exiting the warehouse, and the elevating frame lifts the mobile platform and vehicle upwards to separate them from the fixed platform, and the transfer device moves them to the side. There is no need to once exit the vehicle outside the garage through the entrance/exit, which is a hindrance to entering/exiting the garage, as in the past, and smooth entry/exit operations are possible.
