A plunger (17) that is extendably inserted into the hydraulic cylinder (1) supported by the hydraulic cylinder (1) is pivotally connected to the link member (22), and the operation of the plunger (17) causes the link member (21) to By swinging the upper parking platform (22), the upper parking platform (3) can be raised and lowered while maintaining a state parallel to the base (2).

Further, as shown in FIGS. 7 to 11, the rotating mechanism (8) supports a plurality of rolling elements (9a) mainly consisting of balls on the back side of the pallet (9), and rotates these rolling elements. The pallet (9) is movably supported on the upper surface of the upper parking platform (3) via a moving body (9a), and the upper surface of the upper parking platform (3) has a beak shape when viewed from above. A guide groove (3a) is provided, and a guide body (9b) that engages with the guide groove (3a) on the back surface of the pallet (9).
At the same time, a hydraulic cylinder (24) is installed at the rear of the upper parking platform (3), and a plunger (25) that is telescopically inserted into the cylinder (24) is coupled to the pallet (9). It composes.

As shown in FIG. 11, the hydraulic cylinder (24) is housed inside the upper parking platform (3) as a flat closed box, and the plunger (24)
A cylindrical coupling body (25a) is attached to the tip of the pallet (25), and this coupling body (25a) is rotatably fitted to the shaft body (9C) provided at the food center position of the pallet (9). , the plunger (25) is operatively connected to the pallet (9).

As the plunger (25) expands, the pallet (9) moves linearly forward, and the guide body (9b) is guided by the bent part of the guide groove (3a), causing the shaft body (9C ).

The guide groove (3a) may be formed into an L-shape with a bent portion at a right angle as shown in FIGS. 7 to 11, but the bent portion may be curved as shown in FIG. The bent portion may be an obtuse angle as shown in FIG.

The pivoting position of the pallet (9) with respect to the base (2) is determined by the distance between the guide body (9b) and the shaft (9c), and when a pivoting space can be secured above the front position of the lower parking section (10). In this case, the distance is made longer, and when the shaft body (9c) is located at the rear end of the guide groove (3a), the guide body (9b) is inserted into the guide groove (3a).
If the spacing is set so that the plunger (25) is located near the bending part, the rotation starts at the beginning of the extension movement of the plunger (25), and the forward protrusion of the pallet (9) with respect to the upper parking platform (3) can be reduced. Moreover, if the interval is shortened, the pallet (9) will start turning after moving forward, which is preferable when the turning space above the front position of the lower parking part (10) is restricted.

In the first embodiment shown in FIGS. 1 to 4, a pair of loading/unloading plates (26) are provided in the front part of the pallet (9) so as to be able to enter and exit the upper parking platform ( 3) is moved to the front position of the lower parking part (10) and the pallet (9) is rotated, so that vehicles can be easily entered and removed from the pallet (9).

In addition, when using the loading/unloading board (26), a pneumatic or hydraulic cylinder (27) is installed in the pallet (9) as shown in FIGS. 14 and 15, and the cylinder (27) is extendably inserted. The plunger (28) to be fitted is connected to the loading/unloading plate (26) via an interlocking body (29), and hydraulic operation enables the pallet (9) to be moved in and out.

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

Vehicles can freely enter and leave the lower parking area (10), and in order to move a vehicle into and out of the upper parking area (3), first actuate the hydraulic cylinder (7) that constitutes the reciprocating mechanism. The upper parking lot (3) is maintained in the raised position by the traveling device (5) via the arm member (6) and moved from the rear position shown in FIG. 2). Then, in this forward position, the hydraulic cylinder (16) of the lifting mechanism (4) is operated,
By swinging the link members (21) and (22) by the contraction operation of the planter (17), the upper parking platform (3) is lowered as shown in FIG. 3.

Next, the hydraulic cylinder (24) of the swing mechanism (8) is operated, and the plunger (25) is extended to swing the pallet (9). After this swing, the loading/unloading plate (26) (26) and pull out the pallet (
9) allows vehicles to enter and exit the warehouse.

After the loading and unloading is completed, the pallet (9) is first rotated and returned to its normal position by the reverse procedure of the above-mentioned operation, and then the upper parking platform (3) is raised, and then the lower parking platform (3) is raised. The vehicle is moved back to the rear position corresponding to the parking section (10).

Therefore, while two vehicles can be parked three-dimensionally across the lower parking area (10) and the upper parking area (3) as described above, when a vehicle enters or exits the upper parking area (3), the lower parking area (10) You can leave the parked vehicle without having to take it out of the garage.

Furthermore, the upper parking platform (3) is positioned in front of the lower parking section (lO) and lowered, and entry and exit is carried out at this position. Since the pallet (9) is provided so that it can be turned through the pallet (9), even if the road width in front of the lower parking area (10) is narrow, vehicles can easily enter and leave the upper parking platform (3). It can be done.

In the first embodiment described above, a Nazarus type lifting mechanism was used as the lifting mechanism (4).
A parallel link type elevating mechanism may be used as in the second embodiment shown in the figure.

In the second embodiment shown in FIGS. 16 to 19, a base member (1) is integrally formed with a base (2).
) A pair of parallel supports (31) and (32) are erected on the left and right sides of the front part so that they can be collapsed, and the upper parking platform (3) is supported at the tips of these supports (31 and 32). A pair of hydraulic cylinders (33) are provided between the rear part of the upper parking platform (3) and the base member (1).

Therefore, the hydraulic cylinder (33) is operated, and the planter (34) is telescopically inserted into the cylinder (33).
By extending the column, the pillars (31) and (32) tilt forward and lie down as shown in Figures 18 and 19, and the upper parking platform (3) moves forward and downward in parallel while maintaining its horizontal state. Moreover, the contraction of the plunger (34) causes the columns (31) and (32) to stand up, and as a result of this standing up, the upper parking platform (3) moves rearward and upward while maintaining a horizontal state, The vehicle is moved back from the front position to the rear position corresponding to the lower parking area (10).

Therefore, in the second embodiment, the pillars (31) (32)
This constitutes a parallel link mechanism, and the lifting mechanism (
In other words, the lifting mechanism (4) also serves as a reciprocating mechanism, and the upper parking platform (3) is moved back and forth and raised and lowered at the same time.

Note that the upper parking platform (3) of the second embodiment also rotatably supports a pallet (9) via a rotation mechanism (8) as in the first embodiment.

In addition, in each of the embodiments described above, an elevating mechanism is used that moves up and down by the swinging movement of the link member and the support that corresponds to the link member. A body or a wall is provided to form a box shape, and a traveling device is provided on this upper parking platform to enable it to move back and forth.
Alternatively, it may be supported by a hanging body such as a rope, and raised and lowered manually or by a lifting device such as an electric chain block or winch.

Moreover, although the base (2) was provided separately from the base member (1) and the lower parking part (10) was formed on this base (2), the base (2) is not necessarily required.

When the base (2) is not used, the lower parking section (10) is formed using the ground of the parking space, but in this case, in the first embodiment, a guide rail is provided to guide the traveling device (5). Furthermore, in the second embodiment, it is preferable to provide a frame member that supports the link members (31) and (32).

In addition, using the turning mechanism (8) to make the pallet (9) turnable makes it easy to move vehicles into and out of the upper parking platform (3) even when the road width is narrow, as described above. Although it is preferable, it may be omitted, and although the hydraulic cylinder (24) is used as the turning mechanism and the structure is configured to turn by the linear movement of the plunger (25), it is also possible to use a rotational drive source such as an electric motor or a hydraulic motor. It may also be in a turntable format. When a hydraulic cylinder (24) is used as in the embodiment, the installation space can be reduced and hydraulic operation is possible, which is advantageous in terms of cost compared to the case where a drive source such as a motor is provided separately.

Furthermore, although the lower parking section (10) and the upper parking platform (3) each park one vehicle, they may park two or more vehicles, or may be used in parallel.

When used in parallel, it is preferable to share the base member (1) shown in the example, for example.

(Effect of the invention) Since the present invention is configured as described above, the lower parking section (10)
Although vehicles can be parked three-dimensionally in the upper parking area (3) and the upper parking area (3), when entering and exiting the upper parking area (3), the vehicle parked in the lower parking area (10) does not have to be taken out each time. , you can do it while parked.

Therefore, vehicles can be easily entered and exited from the upper parking platform (3), and the time taken to enter and exit the parking space can be shortened.

Furthermore, by rotatably supporting the parking pallet (9) on the upper parking platform (3) via a turning mechanism (8), vehicles can enter and leave the upper parking platform (3) even if the road width is narrow. Since this can be done parallel to the road, that is, in a direction perpendicular to the front and back positions of the lower parking area (TO), there is no need to steer the vehicle, and therefore easy entry and exit is possible.
