Each of the rear supports 14 may be provided with a shock absorber (buffer) 141. In this embodiment, the spring at the upper end of the rear support 14 is used as a shock absorber, and when the return device 4 is returned to the return position. The shock applied to the rear portion of the upper parking portion 2 is absorbed.

The upper parking section 2 generally has a sleeve member 21, an upper platform 22, a rear block projection 23, and a hanging rope 24.
Of these, each sleeve member 2 of a set of sleeve members 21
Numeral 1 is supported on the upper portion of each central support column 12 while being supported by a shaft 13, and has a C-shaped cross section. The cross-sectional shape may be V-shaped. The upper platform 22 has a pair of I-shaped beams 221 (see FIGS. 4 and 5). The I-beam has an I-shaped cross section and is held by each sleeve member 21 in a slidable manner. Normally, when the vehicle is moved rearward by the return device 4 and returned to the return position, the center of gravity of the upper parking portion 2 is located between the rear column 14 and the central column 12, respectively. Each sleeve member 2
1 has a shaft hole 210, and the shaft 13 is rotatably engaged. Thereby, the sleeve member 2

In addition, the head is slidable in contact with the vertical wall 221a of the I-shaped beam 221 shown in FIG.
Alternatively, when performing a return operation from the inclined state, the I-beam 221 in the sleeve member 21 is prevented from suddenly sliding.

The tilting device 3 has a drive motor 31, a lower reel 34, and an operating wire 33. The drive motor 31 is attached to the rear end of the upper platform 22 and has an upper reel 32 connected to a motor shaft of the drive motor 31. The lower reel 34 is rotatably attached to the lower portion of the center support 12 of the support frame 1. Further, the operation wire 33 is connected to the upper reel 32 at the lower end portion 331.
, While the upper end portion 332 is hung on the upper reel 32. In addition, the operation wire 33 is provided between the upper reel 32 and the lower reel 34, the upper guide roller 321 rotatably installed at the rear of the upper platform 22, and the lower guide roller 321 rotatably installed above the central support 12. It is hung on the side guide roller 341. When the drive motor 31 is operated, the operation wire 33 is wound around the upper reel 32, and the wire length between the upper reel 32 and the lower reel 34 is shortened. As a result, the upper platform 22 is moved forward, and when the upper vehicle U is moved forward until the center of gravity of the upper platform 22 and the upper vehicle passes over the shaft 13, the upper platform 22 tilts.

The apparatus of the embodiment is provided with a manual tilting device (manual tilting means) 3a. Even when the driving force is insufficient and the operation of the driving motor is stopped, the device is manually moved upward. The parking section 2 can be tilted. The manual tilting device 3a has a drive wheel 31a and a gear set 32a. The drive wheel 31a is rotatably installed below the central support 12 of the support frame 1. The drive gear set 32a is rotatable, and is engaged so as to rotate with the drive wheel 31a and the lower reel 34 of the tilting device 3.
Therefore, the operation wire 33 is moved by using the manual tilting device 3a.
Is wound on the lower reel 34, the wire length is shortened, and the upper platform 22 is moved forward and tilted.

The return device 4 includes at least a first return spring 41 which is a tension spring and a second return spring 4 which is a compression spring.

11 is held at the front portion 22a of the platform and its rear end 412 is held in the middle of the sleeve member 21. The second return spring 42 has a front end 421 held in the middle of the sleeve member 21 and a rear end 422 connected to the upper platform 2.
2 at the rear end 22b.

The retraction device 5 includes a pull wire 50, a lower return spring 55, a rearmost roller 53, and a bottom roller 52. The pulling wire 50 has an upper end portion 51 held at a rear portion of the sleeve member 21 of the upper parking portion 2, and a lower end portion 54 engaged with a projection 62 of the lower platform 6. A plurality of wheels 61 are mounted on the lower platform 6 and are held rotatably so that the lower platform 6 can be moved. The lower platform 6 is mounted on a base 11 installed on the ground floor G. The lower return spring 55 is configured such that the projection 62 and the lower fixed end 54 of the puller wire 50 are connected to the base 1 of the support frame 1.
It is held so that it is located at the center of the. The rearmost roller 53 is rotatably held at the rear end of the base 11. Therefore, via the rearmost roller 53,
The tension wire 50 positioned in a tension state between the upper fixed end 51 and the lower fixed end 54 can be wound up. Further, the bottom roller 52 is rotatably installed below the rear column 14 of the support frame 1 and guides the pulling wire 50 between the upper fixed end 51 and the rearmost roller 53. Thus, when the upper platform 22 is tilted forward, the rear portion of the sleeve member 21 is raised, and the pull wire 50 is pulled upward.
When the lower platform 6 is pulled rearward by the pulling wire 50 via the bottom roller 52 and the rearmost roller 53, the lower vehicle L is shown by a solid line from a state shown by a broken line as shown in FIG. Since the upper platform 22 is moved backward to the state, it is not damaged even if the upper platform 22 is tilted downward.

As shown in FIG. 4, the wheel 61 of the lower platform 6 slides in a bottom guide rail 111 formed on the base 11 of the frame 1.

As shown in FIGS. 9 and 10, when the shape of the lower platform 6 is extended, the four wheels of the lower car L can be moved. The car can be moved regardless of which tire is locked by the hand brake. However, FIGS.
And a relatively long platform 6 targeting only the rear (or front) two wheels and a relatively long platform targeting the four wheels shown in FIGS. 9 and 10. 6a merely differs from the embodiment, and any of them may be used.

In order to drop the upper car U parked in the upper parking section 2, the drive motor 31 of the tilting device 3 is operated to rotate the upper reel 32 in the direction of the arrow W. When wound on the upper reel 32, the length of the portion of the actuation wire 33 between the upper reel 32 and the lower reel 34 is shortened, and the upper platform 22 and the upper car U parked thereon are separated by two. It is pushed forward so as to slide inside the sleeve member 21. The upper car U is pushed forward, and the weight of the upper car U and the weight of the upper parking portion 2 in the direction of gravity (biasing force) F
When the center of gravity G1 exceeds a predetermined position, two return forces generated by the first and second return springs 41 and 42 are applied to a reaction force F2 which is pulled downward by the wire 50 drawn by the lower vehicle shown in FIG. When the force exceeds the sum of the forces F3 and F4, the upper parking portion 2 is tilted forward to form an inclined ramp, and the upper vehicle U is moved downward toward the ground G.

As shown in FIG. 3, the force (biasing forc
e) If F1 is at a distance D1 from the shaft (rotation axis) 13 and the end 51 of the puller wire is at a distance D2 from the shaft 13, the following equation holds. F1 × D1> (F2 × D2) + F3 + F4 where F2 is the weight of the lower car L and the lower platform 6
And the reaction force generated by the repulsion force of the lower return spring 55.

As shown in FIG. 8, when the height of the parked lower vehicle La is high, the upper platform 22
Is moved so that a longer “ramp distance” L2 is set so that the ramp distance L2 is longer than the distance L1 when the height of the lower car L shown in FIG. 7 is low,
This prevents damage to the roof of the larger vehicle La parked in the space 60 below the upper parking unit 2.

The lower car L is small and has a support (shaft) 13.
When the distance extending along the upper platform 22 of the front part is a short ramp distance L1, the angle between the upper platform 22 and the ground G is defined as a first inclination angle A1, and the shaft (post) 13 from the ground G is formed. If the height is indicated by the symbol "H", the following equation is obtained. SinA1 = H / L1 Here, in the case of the long ramp distance L2, the angle formed by the upper platform 22 and the ground G is the second angle as shown in FIG.
Assuming the inclination angle A2, the following equation is obtained. SinA2 = H / L2 Since the distance L2 is longer than the distance L1 (L2> L1), the value S
inA2 is smaller than the value SinA1. This is the angle A2
Indicates that the angle is smaller than the angle A1, thereby preventing the roof of the vehicle La below from being damaged.

As described above, when the vehicle U is to be lowered from the upper platform 22, the lower vehicle L is automatically retracted, so that the lower vehicle L is not damaged. Thus, the present invention provides a safer two-stage multilevel parking device.

The present invention is not limited to the apparatus of the above embodiment, but can be variously modified without departing from the gist of the present invention. For example, if a vibration that adversely affects the device due to sudden impact is generated at the time of tilting operation or return operation of the upper platform 22, such vibration is attenuated by a shock absorber system using water pressure or hydraulic pressure. May be prevented. Further, a control device that interrupts the operation and keeps the state for a while may be attached. That is, a lock mechanism (not shown) is provided so that the upper platform 22 is tilted, and when the car parked thereon is moved downward (or upward), the reel 3
4 and the wheel 31a may be locked for a while.

Further, the working wire 33 of the tilting device disclosed in the present embodiment and the pulling wire 5 used for the retraction device are used.
As 0, various ropes including a steel wire rope can be used.

[0033]

As described above, according to the present invention, the upper platform is moved forward to form an inclined ramp connecting the upper parking portion where the upper car is parked and the ground,
At this time, since the lower platform is moved rearward, the lower vehicle parked on the lower platform is lowered rearward. Therefore, it is possible to prevent an accident in which the lower vehicle comes into contact with the inclined upper platform and damages the lower vehicle.

Since the rear block projection is provided at the rear end of the upper platform so as to protrude upward, the upper vehicle does not slip off the upper platform. In addition, since the spherical head of the shaft protrudes inward from the central support, the movement of the shaft hole formed in each sleeve member is restricted in a rotatable state. Further, since the head is slidable and abuts against the vertical wall of the I-shaped beam, sudden sliding movement of the I-shaped beam in the sleeve member at the time of tilting or returning operation is prevented.
