DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. A pit 2 is formed of concrete or the like by digging the ground 1. A gantry 8 is installed along both inner side surfaces inside the pit 2, and a lower arm projecting upward from a rear end of the lower pallet 3 at a rear end of the gantry 8 at a rear end of the pit 2. The upper end of 9 is pivotably supported by a shaft 9a.

As shown in FIG. 1, a lower end of an upper arm 10 hanging downward from a position slightly rearward from the center of the upper pallet 4 is pivotally supported on a base 8 by a shaft 10a. And the pivotal position by this axis 10a is pit 2
It is located at a position slightly shifted backward from the central part of the inside.
A rotation drive means 5 for rotating and driving the upper pallet 4 is attached to the gantry 8. In the embodiment shown in the attached drawings, an example is shown in which the rotary drive means 5 is a jack 5a. Jack 5a
Various types of conventionally known jacks can be used, but a screw type jack called a so-called "Dharma jack" is shown in the accompanying drawings. As shown in FIG. 8, the lower end of the jack 5a is rotatably mounted on the gantry 8 by a shaft 12, and the upper end of the jack 5a is rotatably mounted on the upper pallet 4 by a shaft 13. One jack 5a of jacks 5a on both sides
A geared motor 14 is mounted on the input shaft 15 of one jack 5a and a belt 1 as shown in FIG.

The upper pallet 4 and the lower pallet 3 are connected by an interlocking means 6. The interlocking means 6 rotates the lower pallet 3 in conjunction with the upper pallet 4 when the upper pallet 4 is in a forwardly inclined position. When the upper pallet 4 is in a horizontal parking posture or a forward-lowering position, the upper pallet 4 does not rotate even if the upper pallet 4 is driven to rotate by the interlocking means 6. In the embodiment shown in FIGS. 1 and 7,
A pipe 21 having a hole 20 at one end is connected to a rod 2 from the other end.
2 is slidably inserted into one end of the rod 22.
The stopper 23 at the other end of the pipe 21 is freely engageable with the stopper 23 at the end of the pipe 21. Here, the contact portion 23 is provided with a cushioning rubber 23a. In the embodiment, the rod 22 is composed of a screw rod 25 and upper and lower female screw cylinders 26 in which both ends of the screw rod 25 are freely screwed deep and shallow.
The length of the rod 22 can be adjusted by changing the screwing depth of the screw rod 25 to the female screw cylinder 26. Here, the contact portion 23 described above is provided in one female screw cylinder 26, and a hole 27 is provided in an end of the other female screw cylinder 26. In the figure, reference numeral 28 denotes a lock nut, which is adapted to be tightened after adjusting its length. The holes 20 and 27 are respectively provided on the shaft 2
The upper pallet 4 and the lower pallet 3 are rotatably supported by 9 and 30. Then, when the interlocking means 6 is attached in this manner, when the upper pallet 4 is in the forwardly inclined position, the contact portion 23 does not hit the stopper 24 as shown in FIG. When the lower pallet 3 is in a horizontal parking position at the bottom of the pit 2 and the lower pallet 3 is in a horizontal parking position, the contact portion 23 hits the stopper 24. Therefore, when the upper pallet 4 is in the front-up tilted position, The lower pallet 3 rotates in conjunction with the upper pallet 4 and does not rotate when the upper pallet 4 is driven to rotate by the interlocking means 6 when the upper pallet 4 is in a horizontal parking position or a forward-down position. The interlocking means 6 is not limited to the one shown in FIG. 7, but a bar 31 having a hole 20 at one end is provided at the other end of a strip 32 having a hole 27 at one end as shown in FIG. Inserted into the insertion hole 33
The nut 35 may be screwed into the external thread portion 34 at the tip of the nut so as to be freely deep and shallow. Further, as shown in FIG. 13, the interlocking means 6 is constituted by a wire 36, and when the lower pallet 3 is in a horizontal parking posture and the upper pallet 4 is inclined forward and downward, the wire 36 has slack, and the upper pallet 4 And lower pallet 3
Are set so that the wires 36 are tightened in a horizontal parking posture, and in this case, when the upper pallet 4 is turned to the front-up inclination, the lower pallet 3 is also turned to the front-up inclination by the wires 36. Things. In FIG. 14, a rod 37 is disposed between the lower pallet 3 and the upper pallet 4, and the rod 37 is pivotally supported by the shaft 38 in the holes of the lower pallet 3 and the upper pallet 4. In this case, At least one of the holes of the lower pallet 3 to the upper pallet 4 may be formed as an elongated hole 39 as shown in FIG. In this embodiment, when the upper pallet 4 is inclined forward and downward, the shaft 3
8 does not hit the upper edge of the long hole 39, and the shaft 38 hits the upper edge of the long hole 39 in a state where the upper pallet 4 is in a horizontal parking posture, and the upper pallet 4 tilts forward. The lower pallet 3 is rotated so as to be inclined forward and upward.

In FIG. 1, reference numeral 40 denotes a gantry 8 and an upper pallet 4.
When the upper pallet 4 rotates clockwise in FIG. 1 ( that is, when the upper pallet 4 rises), a load for raising the pallet 4 is large, and the lifting speed is low. When descending, the descending speed increases, but this auxiliary damper member 40 serves as a damper when the upper pallet 4 descends, and the descending speed is reduced to make the ascending and descending speeds substantially equal. By providing the auxiliary damper member 40, the size of the jack 5a can be reduced. Reference numeral 41 in the figure denotes a bogie provided on the upper pallet 4.

Thus, as shown in FIG. 4, the car 7 is parked on the lower pallet 3 disposed in the pit 2 and on the upper pallet 4 disposed above the pit 2, and two-stage parking is performed. However, in this case, the lower pallet 3 and the upper pallet 4 are in a horizontal parking position, so that the vehicle can be stably parked. Here, when the vehicle 7 enters and exits the upper pallet 4, the rotation driving means 5 is driven so that the upper pallet 4 is shifted from the horizontal parking posture to the forward inclined position as shown in FIG. The upper pallet 4 is rotated to position the front end of the upper pallet 4 near the upper end of the front end of the pit 2. In this state, the vehicle 7 enters and exits the upper pallet 4; Of the car 7 parked on the lower pallet 3 maintaining the horizontal parking posture when the upper pallet 4 is in the downwardly inclined position. The space is effectively utilized so that the vehicle does not hit the vehicle on the lower pallet 3 and is inclined forward and downward. When parking the vehicle, the rotation driving means 5 is driven to rotate so that the upper pallet 4 assumes the horizontal parking posture again as shown in FIG. In this case, as described above, since the interlocking means 6 rotates the lower pallet 3 in conjunction with the upper pallet 4 when the upper pallet 4 is in the forwardly inclined position, the upper pallet 4 is moved forward and downward. In the inclined posture and the horizontal posture, the lower pallet 3 is not linked, and the lower pallet 3 holds a horizontal parking posture. On the other hand, in order for the vehicle 7 to enter and exit the lower pallet 3, the rotation driving means 5 is driven from the state of the horizontal parking posture, and the upper pallet 4 is rotated to the front upward inclined posture as shown in FIG. Then, as shown in FIG. 6, the lower pallet 3 is rotated from the horizontal parking position to the forward-upward tilt position by the interlocking means 6 because the upper pallet 4 is rotated in the front-up tilt position, and the front end of the lower pallet 3 is moved. It is located near the upper end of the front end of the pit 2, and the vehicle 7 enters and exits the lower pallet 3 in this state. Then, when the vehicle 7 enters the lower pallet 3 in this way, the rotation driving means 5 is driven to return the upper pallet 4 from the upwardly inclined position to the horizontal parking position. In this case, when the upper pallet 4 rotates, the lower pallet 3 also rotates by the interlocking means 6 so that the lower pallet 3 assumes a horizontal parking posture at the bottom of the pit 2. In this way, both the lower pallet 3 and the upper pallet 4 park the car 7 in a horizontal parking posture, and the two-tiered parking is performed stably.

The mounting position of the upper arm 10 in the front-rear direction on the base 8 and the upper pallet 4 and the mounting position of the interlocking means 6 in the front-rear direction on the lower pallet 3 and the upper pallet 4 by means of bolts can be appropriately selected. 8, upper pallet 4,
A plurality of mounting holes 50 are provided in the front-rear direction of the lower pallet 3, and the upper arm 1 is provided in accordance with site conditions such as the depth of the pit 2.
