b, the left and right fixed rails 40a, 40b, and swing rails 40c to 40f complete a substantially horizontal circular orbit centered on the vertical axis M.

Next, the effect will be explained.

It is now assumed that the lifting lift 14 is waiting on the side of the parking device 1, and the mounting body 19 is positioned and fixed to the lifting lift 14 by the first positioning and fixing device 23 without the pallet 4 mounted thereon. Further, the second positioning and fixing device 24 holds the clamping arms 24c and 24d in an open state. The turntable 25 is stopped at a position where the protrusion 34 engages with the central limit switch 32. The entrance/exit 13 is closed by an opening/closing door 13a.

If you want to unload the parking device from this state, press the unloading button (not shown) corresponding to the desired pallet 4 on the control panel (not shown), and the parking device 1 will first be activated.
As a result of the operation, the 4 groups of pallets repeat the circular movement of alternating pitches vertically and horizontally, and the desired pallet 4 completes its movement to the front row side of the left vertical transfer path 3a.

Next, by releasing the interlocking of the lateral transfer device 5 and causing only the front row side to drive independently, the front row side row is moved one pitch to the left, and thereby the desired pallet 4 is transferred onto the loading body 19. The desired pallet 4 is moved between the clamping arms 24c and 24d by the subsequent operation of the second positioning and fixing device 24 (the rod extension operation of the air cylinder 24f).
is held in place and fixed in position (double-dashed line in Figure 4).

From this state, the elevating lift 14 is raised by driving the motor 17 in the upward direction. During this ascent, the vehicle W mounted on the desired pallet 4 passes through the rectangular hole 11.
a, and the rectangular opening 25 of the turntable 25.
It comes out above a.

Immediately before the desired pallet 4 is fitted into the rectangular opening 25a, the first positioning and fixing device 23 is deactivated (rod shortening operation of the air cylinder 23a).
As a result, the engaging member 23b separates from the engaged bar 23c to release the positioning and fixing of the mounting body 19, and then the roller 37 reaches the entrance of the guide passage 38 and is guided by the guide members 38a and 38b, As a result, the pallet 4 fits into the rectangular opening 25a while being correctly adjusted in position with respect to the turntable 25, and the lifting lift 14 stops when the turntable 25 and the pallet 4 are flush with each other.

At the final position of the lift 14, the lift rails 21a and 21b, the left and right fixed rails 40a and 40b, and the swing rails 40c to 40f complete a circular track as described above.

Thereafter, the turntable 25 is rotated 90 degrees clockwise by the drive of the reversible motor 29, and stopped when the projection 34 engages the limit switch 33. Then, the driver opens the opening/closing door 13a, enters the vehicle entry room 12 through the entrance/exit 13, gets into the vehicle W, and exits to the external roadway R through the entrance/exit 13 by driving forward.

When parking the vehicle, the turntable 25 is rotated 90 degrees clockwise after the vehicle W enters forward, and the vehicle W is stored in the parking device 1 in the completely reverse order of the unloading operation.

Incidentally, although the above-mentioned embodiments have been described as fully automatic operation, the present invention is not limited to this, and a part of the operation may be performed manually.

In addition, the position of the entrance/exit 13 is the turntable 2.
Regardless of the angular position of the limit switches 30 to 33, the limit switches 30 to 33 can be installed in any angular position relative to the center of rotation of the limit switches 30 to 33, and can be implemented in the same manner by simply changing the arrangement of the limits.

Furthermore, if the position of the pallet coupler is shifted for each stage, it is also possible to provide the parking device in multiple layers.

As detailed above, according to the present invention, a turntable is provided on the fixed floor of the boundary opening that communicates the vehicle entry room and the hoistway, and the turntable is placed in the center of the turntable on the mounting body when the lifting lift is raised. A rectangular opening into which a pallet can be inserted is formed, and the turntable, pallet, and mounting body can be rotated as a unit in this inserted state, and an entrance/exit opening leading directly to the external roadway is formed in the building wall that forms the vehicle entry room. Because of this, there is no need to provide a special vehicle turning room, and the site can be used effectively.Also, the entrance can be positioned in any direction, which is no longer subject to restrictions on the direction of vehicle entry. The parking facility can be installed in a difficult location, and all operations for entering and exiting the parking facility can be performed by forward driving, so even beginners can enter and exit the parking facility safely and with peace of mind.
