Abstract

PURPOSE:To safely park automobiles by turning upper and lower parking stands thus moving the front side of each stand vertically, flattening the parking face of the upper parking stand, enabling the lower parking stand to be curved, and making a portion in front of their middle portion horizontal. CONSTITUTION:To use a parking stand 1, it is vertically turned about a horizontal rotating shaft 17 as a hydraulic cylinder 18 contracts; then the lower surface of a parking stand 2 abuts the bottom surface 3a of a pit 3 and the front end 22 of the stand 1 abuts a road G; thereby a stopper sensor 19 is operated to stop the hydraulic cylinder 18; then a vehicle 4 on the road G is moved onto the parking stand 1. To use a parking stand 2, the parking stands 1, 2 are turned upward by expansion of the hydraulic cylinder 18, a front stand 2a is hoisted using a connecting rod 14, and when the front end 21 of the stand 2 aligns with the road G the sensor 19 is operated to stop the cylinder 18; a support shaft 12 is also moved upward. The inclination angle of the entire parking stand 2 is therefore decreased to make effective use of the pit space and to eliminate the need for boring deep in the ground, thus facilitating construction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-tiered parking system, and more particularly to a two-tiered parking system that allows a vehicle to be parked on two upper and lower tiers.

[0002]

2. Description of the Related Art Conventionally, various two-stage parking devices have been proposed and put to practical use, for example, Japanese Patent Laid-Open No. 4-26197.
The one disclosed in Japanese Patent No. 0 is known. This two-tiered parking system is composed of an upper parking garage located on the ground and a lower parking garage located in an underground pit. It rotates up and down according to the road in and out. By the way, the upper parking pedestal is formed to be bendable at an intermediate portion so that the rotation angle does not become too large, and is formed to be bent like a mountain at the intermediate portion during parking. Also,
The bottom of the underground pit that houses the lower parking pedestal was formed in a slanted shape so as to conform to the shape of the lower parking garage when it was rotated downward, so that the underground pit was not too deep. .

[0003]

However, in the above parking device, the upper parking pedestal has a mountain-shaped bending in the middle and the front side is steeply inclined, so that it is difficult to secure the field of view when the vehicle is put in. In addition to being caught in feeling and fear, at the beginning when entering the vehicle, you must first step on the accelerator strongly to apply a load to the engine and loosen the accelerator at the moment when you cross the bend, so adjust it Is also tense.

Also, since the structure in which the middle part of the upper parking lot is bent in a mountain shape is adopted and the bottom surface of the underground pit is formed in an inclined shape, it is not necessary to dig the ground too deep, There was a problem that it was troublesome and inefficient to construct the pit bottom diagonally.

The present invention solves the above problems and allows a vehicle to be safely parked on an upper parking garage without giving the driver a feeling of anxiety or fear, and construction of an underground pit is easy. Its purpose is to propose a two-stage parking system.

[0006]

As a means for solving the above-mentioned problems, a two-tiered parking system according to the present invention comprises an upper parking pedestal arranged on the ground and a lower parking pedestal arranged in an underground pit. By vertically and horizontally rotating the parking pedestals of the upper and lower tiers integrally or independently around a horizontal rotation shaft provided on the rear side. While allowing the vehicle to be taken in and out, the parking surface of the upper parking pedestal is integrally formed in a flat shape, while the lower parking pedestal is formed to be bendable in the front-rear intermediate portion and the lower parking pedestal is lowered. In the rotated state, the rear part of the intermediate part is inclined downward toward the front, and the front part of the intermediate part is formed to be horizontal along the bottom surface of the underground pit.

[0007]

In the two-stage parking apparatus having the above structure, when the upper parking pedestal is rotated downward by an appropriate drive device, the front end of the upper parking pedestal moves downward and is aligned with the road surface.
In this state, the vehicle can be moved from the road to the parking lot or from the parking lot to the road side.

On the contrary, when the lower parking pedestal is rotated upward, not only the rear portion of the lower parking pedestal but also the front portion of the upper parking pedestal are lifted up by the connecting rods.
When the front end of the front portion is aligned with the road surface, the vehicle can be similarly moved in and out of the lower parking lot.

Further, when the lower parking pedestal is rotated downward, the rear portion from the middle portion inclines downward toward the front, and the front portion bends and is horizontal along the bottom surface of the underground pit. As a result, the inclination angle of the lower parking lot is small as a whole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A two-stage parking system is shown in FIGS.
This two-tiered parking system has an upper parking garage 1 and a lower parking garage 2.
Are integrally formed on the rear side, and the front ends of the upper and lower parking pedestals 2 and 3 are rotated in the vertical direction with the rear end of the lower parking pedestal 2 as a fulcrum. It is installed so that the vehicles 4 and 5 can be taken in and out in conformity with G.

The upper parking pedestal 1 is integrally formed with a plurality of deck members 7 disposed inside the frame member 6 so that the parking surface has a planar shape. A wheel stopper 8 of the vehicle 4 is provided on the rear portion of the parking table 1 so as to project therefrom.

The lower parking pedestal 2 is divided into a front pedestal 2a in the front part and a rear pedestal 2b in the rear part at an intermediate portion in the front-rear direction, and a deck member 10 is arranged inside each frame member 9 for parking. The surfaces are formed in a flat shape, and both are formed to be bendable by being connected to the frame member 9 by a support shaft 12. Further, the rear platform 2b and the upper parking platform 1 are integrally formed via the support columns 13.

A connecting rod 14 is attached between the front platform 2a and the upper parking platform 1. This connecting rod 14 accommodates an inner cylinder 14b, one end of which is fixed to the front base 2a, inside an outer cylinder 14a, one end of which is fixed to the frame member of the upper parking pedestal 1, so that the inner cylinder 14b is slidable and cannot be pulled out. However, the structure is such that it expands and contracts as a whole, but does not extend beyond a predetermined length, that is, a length at which the front platform 2a and the upper parking platform 1 are substantially parallel.

The upper parking pedestal 1 is arranged on the ground, and the lower parking pedestal 2 is arranged in the underground pit 3. The underground pit 3 is formed by digging the ground in a concave shape, and the bottom surface 3a is formed in a horizontal state. Support base 1 at the rear end of the underground pit 3.
5, a bearing 16 is formed on the upper portion of the supporting base 15 so that the rear end 20 of the lower parking pedestal 2 can rotate on the bearing 16 via a horizontal rotation shaft 17. It is connected. As a result, the parking pedestals 1 and 2 in the upper and lower tiers are connected to the horizontal rotation shaft 1
It becomes possible to rotate up and down with 7 as a fulcrum.

A hydraulic cylinder 18 and a stopper sensor 19 are arranged in parallel between the front bottom surface 3a of the underground pit 3 and the upper parking pedestal 1. The hydraulic cylinder 18 moves the upper parking pedestal 1 up and down, and is operatively connected to a hydraulic cylinder drive device (not shown). The stopper sensor 19 basically has the same structure as that of the connecting rod 14, and the outer cylinder 1
The inner cylinder 19b is telescopically inserted into 9a, and it is detected that the front end 21 of the lower parking garage 2 is aligned with the road G at the extension end and the front end 21 of the upper parking garage 1 is aligned with the road G at the reduction end. Then, the operation of the hydraulic cylinder device is controlled. In addition,
The operation switch (not shown) of the hydraulic cylinder drive device may be arranged at an appropriate position in the parking lot.

By the way, when the upper and lower parking pedestals 1 and 2 rotate about the horizontal rotation shaft 17 as described above, the rear pedestal 2b is in a state where the lower parking pedestal 2 is rotated downward. Is inclined downward toward the front, and the front platform 2a is set to be horizontal along the bottom surface 3a of the underground pit 3. Further, the rotation angles of the upper parking garage 1 and the lower parking garage 2 are set to be substantially the same.

In the two-stage parking apparatus having the above construction, when the upper parking pedestal 1 is used, the hydraulic cylinder 18 is reduced as shown in FIG. 1 so that the upper parking pedestal 1 uses the horizontal rotating shaft 17 as a fulcrum. It may be rotated downward. When the lower surface of the lower parking platform 2 contacts the bottom surface 3a of the underground pit 3 and the front end 22 of the upper parking platform 1 contacts the road G, the stopper sensor 19
Is activated and the operation of the hydraulic cylinder 18 is stopped. In this state, the vehicle 4 on the road G can be moved to the upper parking platform 1 or the vehicle 4 on the parking platform 1 can be moved to the road G side.

On the contrary, when using the lower parking lot 2,
As shown in FIG. 2, the hydraulic cylinder 18 may be extended to rotate the upper and lower parking stands 1 and 2 upward. When the extension of the connecting rod 14 reaches the limit, and beyond this, the lower front platform 2a is lifted by the connecting rod 14 and rises, and when the front end 21 of the front platform 2a is aligned with the road G, the stopper sensor 19
Is activated and the operation of the hydraulic cylinder 18 is stopped, so that the vehicle 5 can be similarly moved in and out of the lower parking pedestal 2. The front platform 2a of the lower parking platform 2 is connected to the connecting rod 1.
When it is lifted by 4 and pivots upward, the rear base 2b also pivots upward, so that the support shaft 12, which is the pivotal fulcrum of the front base 2a, also moves upward. Therefore, the rotation angle of the lower parking pedestal 2 becomes smaller as a whole, and the degree of bending between the front pedestal 2a and the rear pedestal 2b is reduced, so that the field of view does not move much upward and the vehicle is safe and easy. Can be put in and taken out.

By the way, when the lower parking pedestal 2 is rotated downward, the rear pedestal 2b inclines downward toward the front, and the front pedestal a bends to be horizontal along the bottom surface of the underground pit 3. In this state, the lower parking pedestal 2 has a small inclination angle as a whole. Therefore, the bottom surface 3a of the underground pit 3 can be horizontal and the depth thereof can be shallow. Furthermore, without increasing the depth of the underground pit 3 more than necessary, the ground height of the upper parking pedestal 1 is suppressed to make the inclination gentle, and the rotation angles of the upper parking pedestal 1 and the lower parking pedestal 2 are the same. Can be

It should be noted that instead of integrally forming the upper and lower parking pedestals on the rear side as in the above-described embodiment, the upper tier parking pedestal and the lower tier parking pedestal are independently rotatable and
The upper parking garage and the lower parking garage may be configured to be rotated by separate driving devices.

[0021]

[Effects] According to the present invention, the rear portion is inclined forward and downward while the lower parking pedestal is rotated downward, and the front portion is horizontal along the bottom surface of the underground pit. Since the inclination angle of the lower parking lot is small as a whole, the pit space is effectively used. Further, since the bottom surface of the underground pit may be formed horizontally without being inclined, it is not necessary to dig deep underground, and the construction becomes easy.

Further, since the parking surface of the upper parking pedestal is integrally formed in a planar shape, there is a feeling of anxiety and fear associated with the sudden shift of the field of view while the vehicle is being taken in and out. It can be parked safely because it is solved and there is no need for delicate accelerator adjustment.

Further, since the bent portion of the lower parking pedestal is located in the underground pit and is hard to be visually recognized from the outside, the vehicle can be taken in and out safely and the appearance of the vehicle is not damaged.
