Next, FIG. 3 shows a second embodiment of the present invention.
In this example, three vehicles can be parked in three tiers. It should be noted that the steps from the bottom to the second step are the same as those in the previous embodiment, and therefore the same reference numerals are given and the description thereof is omitted.

On both sides of the base 1, a pair of pivoting arms 24 is newly mounted on the left and right sides of the pivoting arms 2 and 4, and the base ends of the pivoting arms 24 are similar to those described above. A driver 26 is provided. Further, a pair of columns 20 are provided symmetrically behind the pivot arm 24, and the pivot arms 22 are rotatably attached to the upper ends of the columns 20 via a support structure shown in FIG. It is installed.

A horizontal elevating table 28 is attached and attached to the tips of the rotating arms 22 and 24 in a substantially horizontal state. The rotary arms 22 and 24 form a link mechanism, and the horizontal lifting platform 28 is provided between the upper position of the horizontal lifting platform 8 and the front position of the first parking surface without interfering with the second-stage vehicle C2. It rotates so as to maintain a substantially horizontal state, and when it lands, it fits in the recess 16.

As shown in FIG. 4, a long hole 32 extending in the front-rear direction is formed at the upper end of the column 20, and a rack 34 having a large number of teeth upward is fixed to the lower surface of the long hole 32. ing. On the other hand, a pinion 38 is fixed to the lower end portion 36 of the rotating arm 22 with its axis oriented in the left-right direction.
It is inserted into the long hole 32 and meshes with the rack 34. As a result, when the rotating arm 22 falls forward as shown in FIG. 5, the pinion 38 rolls on the rack 34 and the center of the arm moves to the front position P2. Moves to the rear position P1.

By moving the arm center in this manner, the horizontal lift 8 can be maintained in a posture close to horizontal even in the upper position. By the way, if the rotation center of the rotating arm 2 is fixed and the third-stage horizontal lift table 28 is landed at substantially the same position as the second-stage horizontal lift table 8,
As shown by the chain double-dashed line in FIG.
The elevation angle of 8 becomes large, and it becomes necessary to strengthen the wheel stopper means of the vehicle C3. On the other hand, in the case of this embodiment,
The elevation angle of the horizontal lift table 28 at the upper position can be reduced by α.

A turntable 30 is provided on the horizontal lift table 28 via a rotating mechanism, like the horizontal lift table 8, and the vehicle C3 mounts a wheel stopper 18 on the upper surface (lift parking surface) of the turntable 30. It is possible to park by hitting the wheels.

According to this embodiment, the vehicle C3 can be moved in and out by independently raising and lowering the third-stage horizontal lift table 28 without interfering with the first- and second-stage vehicles C1 and C2. Further, the third-stage horizontal lifting platform 28 is the second-stage horizontal lifting platform 8
Since it lands almost at the same position as the above, there is an advantage that the installation space is small and the vehicle passage is common even when the turntable 30 is rotated by 90 °.

Next, FIG. 6 shows an example in which parking is possible in four upper and lower stages. The first to third stages are the same as those of the embodiment shown in FIG. On the base 1, each rotating arm 2, 4, 22,
A pair of support walls 40 that are parallel to each other is provided on the left and right outside of 24. At the upper ends of these support walls 40, rotating arms 42 and 44 that form a parallel link mechanism are provided.
Are rotatably attached to each other, and a horizontal elevating table 48 is attached to the tip thereof, so that they can be elevated and lowered while maintaining a horizontal state. A driver 46 is provided at the lower end of the rotating arm 44. Further, a turntable 50 is provided on the horizontal lift 48.

According to this embodiment, the three horizontal elevators 8, 28, 48 can be independently elevated and lowered.

And one end of a chain 68 is wound around each of the stationary gears 66. In addition, each rotating arm 64
Gears 70 are rotatably mounted in the central portion of each of the chains, and each chain 68 is hung on each gear 70 and extended toward the arm tip side.

When each side of the rotary arm 64 on the tip end side is erected, the side on the base end side becomes horizontal and the base 6
It is set so as to be substantially aligned with the upper surface of 0, and in this state, the vehicle C1 mounted on the base 60 can be driven in either the front or rear direction. In addition, in order to facilitate the taking in and out of the vehicle C1, front and rear of the base 60 are provided movable tilting bases (not shown).

One end of a horizontal lift table 74 is rotatably attached to the tip of the rotary arm 64 via a table support shaft (not shown). The base support shaft is fixed to a horizontal lift base 74, and gears 72 are coaxially fixed to both ends of the base support shaft inside each of the rotating arms 64.
The gear 72 has the same outer diameter as the gear 66, and the other end of the chain 68 is wound. Accordingly, when the rotating arm 64 is rotated, the chain 68 rotates the gear 72, so that the horizontal lifting platform 74 is always kept horizontal regardless of the angle of the rotating arm 64.

Also according to this embodiment, the horizontal lift platform 74 can be raised and lowered without interfering with the lower vehicle C1 and the upper vehicle C2 can be easily taken in and out. In addition, since the horizontal lifting platform 74 is directly landed on the ground, the vehicle C2 can be directly dropped on the road.
Further, in this example, since the entire apparatus can be moved, there is also an advantage that the degree of freedom of the installation position is high.

In the embodiment of FIG. 7, a turntable may be provided on the horizontal lift table 74. Further, when it is desired to lower the second vehicle C2 to a position close to the first vehicle C1, the rotation center of the rotating arm 64 is laterally displaced and the arm locus is changed from K1 as shown by reference numeral 66A in FIG. K2
You can change to.

Also in the embodiment of FIG.
It is possible to have a structure in which parking is carried out in multiple steps. An example thereof is shown by a chain double-dashed line in FIG. A pair of frames 78 are provided on both sides of one end of the base 60, and a horizontal lifting platform 86 is attached to the upper ends of the frames 78 via a pivot arm 80 pivoted by a drive device (not shown). A stationary gear 82 is provided at the base end of the rotating arm 80, and
A gear 84 fixed to the horizontal lift 86 is housed in the tip portion, and a chain (not shown) similar to the chain 68 is stretched between the gears 82 and 84. This allows
The horizontal lifting platform 86 always maintains a horizontal posture regardless of the position of the rotating arm 80, and can move from the landing state to above the second vehicle C2.

The present invention is not limited to the above-mentioned respective embodiments, and the structures of the respective embodiments may be appropriately combined, and if necessary, other conventionally known mechanisms may be combined. . Further, a multi-stage parking device may be arranged in the horizontal direction so that a larger number of vehicles can be parked.

[0033]

As described above, according to the multi-stage parking apparatus according to the present invention, each horizontal lifting platform is connected to the base through a plurality of pivoting arms, and the position above the first parking surface is increased. Since it is rotatable while maintaining a horizontal state between the vehicle and the lateral position of the first parking surface, even when the vehicle is parked on the first parking surface, the vehicle can be leveled without interfering with the vehicle. Vehicles can be taken in and out by lowering the platform.

When a turntable and a rotating mechanism are provided on each horizontal lift, the vehicle on the horizontal lift can be easily turned vertically / horizontally, and the vehicle is mounted on the horizontal lift. If it does not exist, it has the advantage that it can also be used to change the direction of the lowest vehicle.
