have. One end of an arm member 49 is fitted to the output shaft 48, and the other end of the arm member 49 is fitted with a wheel 50 with a collar that fits into the concave groove 42 of the lifting floor 41. Then, the output shaft 48 of the speed reducer 45 is rotated by the operation of the motor 47, and the arm member 49 is rotated approximately 180 degrees from the state in which the arm member 49 extends upward or downward from the output shaft 48.
Is in a raised position where it is flush with the ground floor 13 (the position shown in solid lines in FIGS. 1 and 2) and in the bottom position in the pit 12 (the position shown in phantom lines in FIGS. 1 and 2) It is configured to move up and down between and. Incidentally, 51 is a steel plate protection floor provided at the same height position as the ground floor 13 and covering the upper part of the elevating device 44.

Next, the operation of the above-described embodiment, particularly the lifting floor 41 in the pit 12
The operation of the elevating device 44 for elevating and lowering will be described.

When moving in and out of the rear-row parking device 5, the lifting floor 41
As shown by the solid line in FIG. 1 and FIG. 2, the upper surface is located at a raised position where the upper surface is flush with the ground floor 13, and the vehicle travels on the elevator floor 41 and passes through the front ridge 2. Will be done.
At this time, the arm member 49 of the elevating device 44 extends the elevating floor 41 from the output shaft 48 of the speed reducer 45 with the tip end side extending upward, and the wheels 50 engaging with the recessed grooves 42 at the left and right side ends of the elevating floor 41. Since it is supported in the lifted state, the speed reducer is used even when the vehicle passes over the lifting floor 41.
The load torque does not act on 45, the drive shaft 46, the motor 47, and the like. Therefore, in the lifting device 44, only the overhang load of the output shaft 48 of the speed reducer 45 needs to be strengthened, so that it is economical and the lifting device 44 can be downsized. Further, since the upper and lower floors 41 have a flat upper surface and are flush with the ground floor 13, the vehicle can be easily driven.

When the front-row parking device 5 is loaded or unloaded from such a state, in the lifting device 44, a motor is used.
The rotation operation of 47, the rotational power thereof is reduced by the speed reducer 45 to rotate the output shaft 48, and the arm member 49 rotates approximately 180 degrees from the extended state to the extended state. When the arm member 49 rotates, the wheel 50 at the tip of the arm member 49 rolls along the concave groove 42 while being engaged with the concave groove 42 of the lifting floor 41. Further, as the arm member 49 rotates, the lifting floor 41 is guided by the guide rollers 43, 43, ... While descending from an ascending position to a descending position on the bottom side in the pit 12 (see FIGS. 1 and 2). State shown by virtual line). If the lifting floor 41 is located at this lowered position, the chassis 10a will not interfere with the lifting floor 41 even when the chassis 10a of the cage 10 is fitted into the pit 12. In the lifting device 44, the operation of raising the lifting floor 41 from the lowered position to the raised position is the same as the operation of lowering the lifting floor 41 from the raised position to the lowered position.

As described above, the elevating device 44 is arranged on the side of the elevating floor 41 in the pit 12, and the length of the arm member 49, which is a movable member of the elevating device 44, is only half the elevating distance of the elevating floor 41. In addition, the height of the entire lifting device 44 can be reduced in combination with the above-described designing ease of the lifting device 44. For this reason, the depth of the pit 12 can be made as shallow as possible, and the construction can be facilitated and the cost can be reduced.

Moreover, since the ascending / descending speed of the ascending / descending floor 41 changes with a sine wave with respect to the rotation of the arm member 49, there is an effect that the ascending / descending operation becomes smooth.

In the above embodiment, the case where the parking devices 4 and 5 are arranged in two rows has been described, but the present invention can be applied to a case where the parking devices are arranged in three or more rows in the vertical direction. In this case, the lifting floors are arranged in the pits of each parking row except for the rearmost part, and if the lifting devices for lifting these lifting floors have the same configuration as the lifting device 44 in the embodiment, respectively. Good.

(Effects of the Invention) As described above, according to the multi-column vertical circulation parking equipment of the present invention, the lifting floor is supported by the arm member having the wheels at the ends that engage with the grooves of the side edges of the lifting floor. With the structure in which the arm member extends in the vertical direction and rotates approximately 180 degrees to raise and lower the lifting floor in the pit, the entire lifting device can be arranged on the side of the lifting floor, and the lifting device is also provided. Since the length of the movable member (arm member) is half the lifting distance of the lifting floor and the design is easy, the lifting device can be made compact, and the pit depth is made as shallow as possible. Therefore, the construction can be facilitated, the cost can be reduced, and the elevator floor can be raised and lowered quietly and smoothly.
