DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. As shown in FIG. 1, a pit 2 is formed by digging the ground 1 and using concrete or the like. A pedestal 8 is installed along the rear portions of both inner side surfaces inside the pit 2, and the rear end portion of the pedestal 8 is located at the upper end portion of the rearmost end portion in the pit 2 and is located above the rear end portion of the lower pallet 3. The upper end of the protruding lower arm 9 is rotatably supported by a shaft 9a to form a pivotal support A.

As shown in FIG. 1, the lower end of an upper arm 10 that hangs downward at the rear of the upper pallet 4 is rotatably supported by a shaft 10a at the upper end of the pedestal 8, which is rotatably supported. The pivotal position by 10a is located at substantially the same level as the shaft 9a that pivotally supports the upper end of the lower arm 9 projecting upward at the rear end of the lower pallet 3 and is displaced forward of the shaft 9a. ing.

Central pedestals 8a are provided at lower portions on both sides of the substantially central portion of the pit 2, and a pivotal drive means 5 for pivotally driving the upper pallet 4 is attached to the central pedestals 8a. In the embodiment shown in the accompanying drawings, an example in which the rotary drive means 5 is a hydraulic cylinder is shown. Of course, the present invention is not limited to the hydraulic cylinder, and other rotary drive means such as an electric jack can be used. One end of the hydraulic cylinder is rotatably attached to the central mount 8a by a shaft,
The upper end of the rod of the hydraulic cylinder is rotatably attached to the upper pallet 4 by a shaft.

The upper pallet 4 and the lower pallet 3 are connected by an interlocking means 6, which is arranged so that the upper pallet 4 is in a substantially sideways posture (actually, a slightly upwardly raised posture) above the pit 2. Upper pallet 4 when rotated
The lower pallet 3 is rotated in conjunction with the above, and the lower pallet 3 is tilted so as to be in a front rising position.
When the upper pallet 4 is in the front-lowering posture, the lower pallet 3 is in a substantially horizontal posture at the bottom in the pit 2.

A handrail 15 is attached to one end of the upper pallet. Further, in FIG. 2, reference numeral 16 denotes a wheel stopper of the automobile 7. Then, the rotation driving means 5 is driven, and the upper pallet 4 is in a substantially lateral posture above the pit 2 (actually, a slightly upward posture) as shown in an imaginary line in FIG.
And the lower pallet 3 is rotated by the interlocking means 6 so that the lower pallet 3 is inclined so as to be in a front rising position so that the front end of the lower pallet 3 approaches the upper end of the front end of the pit 2. The automobile 7 is moved in and out of the lower pallet 3 in this state. Also, the rotation driving means 5

Upper pallet 4 of lower pallet 3 as described above
In the present invention, since the pivotal support portion of the lower pallet 3 is located above the upper end of the rearmost end of the pit 2 or above the upper end, the locus drawn by the front end of the lower pallet 3 is shown in FIG. As shown in, the pit 2 comes closest to the front inner wall portion 2a of the pit 2 near the upper end of the front end portion. As a result, even if the front inner wall portion 2a of the pit 2 is vertical, the pit 2
The vertical front inner wall 2a does not hinder the rotation of the lower pallet 3 even if it is brought as close as possible to the front end of the lower pallet 3 near the upper end of the front pallet.

In the embodiment of FIG. 1, the pivotal support of the lower pallet 3 is located near the upper end of the rearmost end of the pit 2. However, as shown in FIG. It may be located above the end.

[0014]

As described above, according to the present invention, as described above, there is a substantially horizontal posture along the bottom of the pit which is lower than the ground, and a front rising inclination posture in which the front end is located near the upper end of the front end of the pit. The lower pallet is rotatably arranged in the pit so that the pit can be selected, and the pit can be selected to have a substantially horizontal posture above the pit and a front-down inclined posture in which the front end is located near the upper end of the front end of the pit. Since it is a two-tiered parking system composed of an upper pallet rotatably arranged above the car, the vehicle can be parked on the lower pallet arranged in the pit and the upper pallet arranged above the pit. Two-tiered parking is possible, and of course, by positioning the pivotal support of the lower pallet above the upper end of the rear end of the pit or above the upper end of the pit, the lower pallet can be tilted forward even if the front inner wall of the pit is vertical. When turning to the posture, it does not hit the front inner wall, and as a result, the front end of the lower pallet can be brought as close as possible to the upper end of the front end of the pit with the front inner wall in the pit being vertical. The entry and exit to the lower pallet can be done smoothly, and the front inner wall inside the pit can be made vertical so that the pit can be constructed easily.
