Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a parking system, and particularly to a compact multi-level parking system having parking spaces above and below.

(Prior Art) A multi-level parking system is known that can park one vehicle in two levels, one on top and one on top using a lift, in a plane space for one vehicle.

(Problem to be solved by the invention) However, in the conventional list method, when a vehicle parked on the list and parked in the upper row is taken out or removed, the vehicle parked in the lower row parked below the list is evacuated and then the vehicle parked in the lower row is evacuated. It was inconvenient to use because it had to be lowered. Furthermore, in order to raise and lower the wrist while maintaining the horizontal plane, an interlocking mechanism for raising and lowering the four corners in synchronization is required, resulting in a complicated structure and high cost.

SUMMARY OF THE INVENTION In view of these conventional problems, an object of the present invention is to provide a parking device that allows vehicles in the upper tier to be taken in and out even when parked in the lower tier, has a simple configuration, and can be manufactured at low cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the front end of the vehicle support plate at the front position of the boundary between the upper and lower parking spaces of a frame having upper and lower parking spaces. The end part is supported so that it can move back and forth and up and down along a slightly lower inclined rail, and a telescopic lifting means that can swing back and forth is placed on one side of the rear of the parking space. A guide rail is disposed on the other side, and a moving block is provided that is movable along the guide rail and cannot rotate in the width direction of the parking space, and the rear part of the vehicle support plate is moved by the telescoping lifting means. It is characterized in that the moving block is suspended and supported, and the moving block and the rear part of the vehicle support plate are connected by a connecting rod.

(Function) Since the present invention has the above configuration, when the telescoping elevating means is extended to lower the rear part of the vehicle support plate, the vehicle support plate tilts and rotates downward using its front end as a fulcrum, and the front end also moves downward. The vehicle support plate moves backward along the inclined rail, and while moving backward, the vehicle support plate tilts and rotates until it touches the vehicle entry road surface. Therefore, even if it is constructed compactly using both short support plates, the rear end of the vehicle support plate will touch the ground without interfering with the vehicle parked in the lower parking space, and the vehicle can be placed on this vehicle support plate. It can be brought in and taken out. Thereafter, by contracting the telescoping lifting means, the vehicle support plate is retracted into the frame in a substantially horizontal position above the lower parking space via the opposite path to the above, and the upper part of the vehicle support plate is stored in the frame in a substantially horizontal position above the lower parking space. It will become. It goes without saying that in this state, the vehicle can be moved in and out of the lower parking space at will.

Further, since only one telescopic lifting means is disposed on one side of the parking space and no interlocking mechanism is provided, the structure of the lifting mechanism is extremely simple and can be manufactured at low cost. Moreover, the rear part of the vehicle support plate is connected by a connecting rod to a moving block that is movable along a guide rail placed on the other side of the rear part of the parking space and cannot be rotated in the width direction of the parking space. As mentioned above, the vehicle support plate, whose front end is movable and movable up and down, is supported by suspending one rear side to prevent the vehicle support plate from swinging in the width direction of the parking space even when raised and lowered. This allows the vehicle support plate to be raised and lowered smoothly and safely.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In FIG. 1, a base surface 2 is formed at a low position with respect to a vehicle approach road surface 1, and this base surface 2
A frame 3 constituting the outer frame of the two-story parking device is installed above. Further, the vehicle approach road surface 1 and the base surface 2 are connected by a slope surface 4. The inside of the frame 3 has parking spaces 5a and 5b that can park two vehicles a above and below,
A vehicle support plate 6 is arranged between the upper and lower parking spaces 5a and 5b.

As shown in FIG. 3, this vehicle support plate 6 has rollers 8 provided on both sides of its front end 7a.
It is movably engaged with inclined rails 9 fixedly installed on both sides of the frame 3 so that the rear end side is slightly lower, and the front end 7a of the vehicle support plate 6 is movable back and forth and vertically It is movably supported and is configured to double as a slope for taking vehicles a in and out of the upper parking space 5a.
Further, the front end portion 7a of the vehicle support plate 6 is connected to the frame 3 via a foldable link 10.

As shown in FIG. 2, the rear part 17 of the vehicle support plate 6 has an electric chain block 1 fixedly installed on one side of the upper rear end of the frame 3 as a telescoping lifting means.
One side thereof is suspended and supported by one chain 12. Furthermore, guide rails 13 are provided on both sides of the frame 3 and are inclined at an appropriate angle α so that the rear end side is slightly lower from the middle part to the rear part.
A moving block 14 is provided with a multi-wheel roller consisting of four or eight rollers that is movable along the guide rail. This moving block 14 is supported by a guide rail 13 so as to be movable but not rotatable around a substantially vertical axis, and this moving block 14 and both rear sides of the vehicle support plate 6 are connected via a connecting rod 15. By doing so, when the vehicle support plate 6 rotates up and down, it is guided so as not to swing in the width direction of the parking spaces 5a, 5b. Also, between the rear side edge of the vehicle support plate 6 opposite to the side where the electric chain block 11 is arranged and the frame 3 above it,
A tension spring 16 is interposed as necessary to alleviate the imbalance of forces on both rear sides of the vehicle support plate 6 when the vehicle support plate 6 is raised and lowered.

At an intermediate position between the front portion 7 and rear portion 17 of the vehicle support plate 6, an inclined step portion 18 is formed which slopes downward toward the front end side. This inclined stepped portion 18
is formed at a position to receive the rear wheels of the vehicle a running onto the vehicle support plate 6. In addition, the vehicle support plate 6
is in the inclined state, the angle of inclination of the rear part 17 of the vehicle support plate 6 with respect to the vehicle approach road surface 1 is θ ₁ , and the inclined step portion 1
If the inclination angle of 8 is θ ₂ and the inclination angle of front part 7 is θ ₃ , then
The angle is set so that θ ₂ <θ ₁ <θ ₃ and θ ₂ is an angle close to 0°.

Reference numeral 19 denotes a stopper disposed at the vertically intermediate portion of the rear part of the frame 3, and is configured to engage with the lower surface of the vehicle support plate 6 raised to a substantially horizontal position to maintain that position. The engagement can be released by appropriate means such as the like. 20 is an operation box for the electric chain block 11, 21 is a holo covering the upper part of the frame 3, and 22 is a holo 21
A roof deck 23 is disposed at the rear of the roof deck, and 23 is a cover extending from the bottom thereof. 24 is connected to the link 1 to prevent the vehicle from falling forward.
It is a fall prevention bar installed horizontally above and below between 0 and 0.

In the above configuration, the vehicle support plate 6 is usually the first
As shown by the solid line in the figure, it is placed in a substantially horizontal state and is locked by a stopper 19. In this state, the vehicle a can be taken in and out of the lower parking space 5b by passing through the inclined road surface 4 between the vehicle entrance road surface 1 and the base surface 2. In addition, at this time, the rear part 17 of the vehicle support plate 6 that regulates the upper surface of the lower parking space 5b is positioned upward via the inclined stepped portion 18 in the middle thereof, so that the vehicle a is moved upward via the inclined road surface 4. The vehicle does not interfere with the vehicle support plate 6 even when moving in and out of the vehicle entrance road surface 1 at the position.

On the other hand, when parking in the upper parking space 5a, the vehicle support plate 6 is set in the slope state shown by the imaginary line in FIG. The vehicle support plate 6 on which the vehicle is placed is returned to a substantially horizontal state. At this time, since the vehicle approach road surface 1 is at a higher position than the base surface 2, it is possible to return to the above-mentioned approximately horizontal state by simply rotating the vehicle support plate 6 upward by a small angle, and from the approximately horizontal state to the ground contact state. When rotating the vehicle support plate 6, it can be connected to the vehicle approach road surface 1 by simply rotating it downward by a small angle, allowing the vehicle to be smoothly inserted and removed, and the short vehicle support plate 6
Even if this is used, it is possible to avoid interfering with the vehicle a parked in the lower parking space 5b. Furthermore, since the inclined stepped portion 18 is formed at the intermediate portion of the vehicle support plate 6, when the vehicle supporting plate 6 is in the slope state, the front wheels of the vehicle a move from the rear portion 17 of the vehicle supporting plate 6 to the inclined stepped portion 18. When this transition occurs, since the inclination angle θ ₂ of this portion with respect to the horizontal is smaller than the inclination angle θ ₁ of the rear portion 17, the inclination angle of the vehicle a with respect to the horizontal can be reduced, and the front wheels of the vehicle a shift to the inclined step portion 18. By allowing the rear wheels to ride on the rear end of the vehicle support plate 6 at times, it is possible to prevent the lower surface of the rear end of the vehicle a from coming into contact with the vehicle approach road surface 1. Further, since the inclination angle of the rear part θ ₁ is smaller than the inclination angle θ ₃ of the front part 7, there is an advantage that the vehicle can be easily mounted on the vehicle support plate 6.

Furthermore, when lowering the vehicle support plate 6,
When the chain 12 of the electric chain block 11 is extended, the rear part 17 of the vehicle support plate 6 is lowered, and at the same time, the front end 7a moves rearward along the inclined rail 9, and the vehicle support plate 6 advances rearward. However, even if the vehicle support plate 6 is shortened and the inclination angle is increased, the rear part thereof rotates downward, and as a result, even if the vehicle support plate 6 is shortened and the inclination angle is increased, the slope state is maintained without contacting the vehicle a parked in the lower parking space 5b. It can be configured compactly as a whole. Also, the vehicle support plate 6
When lifting the chain 12 of the electric chain block 11, the vehicle support plate 6 follows the same route in reverse and returns to a substantially horizontal position, and similarly contacts the vehicle a in the lower parking space 5b. There isn't. In addition, the moving block 14 moves along the guide rail 13 in conjunction with the vertical movement of the vehicle support plate 6, and the moving block 14 moves the connecting rod 15.
By restricting displacement in the width direction of the parking spaces 5a, 5b, the vehicle support plate 6 is prevented from swinging in the width direction of the parking spaces 5a, 5b. Even when one side of the vehicle support plate 6 is driven up and down, the vehicle support plate 6 moves up and down smoothly and safely.

The present invention is not limited to the above embodiments. For example, although an electric chain block has been exemplified as the telescoping lifting means, it goes without saying that other lifting means such as a cylinder device may be used.

(Effects of the Invention) According to the parking device of the present invention, as described above, the vehicle support plate tilts and rotates while moving backward until the rear end touches the vehicle entry road surface, so that the vehicle can be parked in the lower parking space. Even when the vehicle is parked, the vehicle support plate does not interfere with the vehicle support plate, so that the vehicle support plate can be shortened and the parking device can be configured compactly. Further, since the telescopic lifting means is simply disposed on one side of the parking space and no interlocking mechanism is provided, the structure of the lifting mechanism is extremely simple and can be manufactured at low cost. In addition, the moving block and the connecting rod can prevent the vehicle support plate from swinging in the width direction of the parking space, and the vehicle support plate can be raised and lowered smoothly and safely, providing great effects.
