Description

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

(Prior Art) Recently, it has become not uncommon for a family to own two or more cars. In cities or nearby areas, it is rare for people to own enough land to park more than one car, and finding a parking space for a second car is often a problem.

In view of this, the present applicant has provided a parking device capable of parking two cars in one parking space, as known from Japanese Utility Model Application No. 61-37350. This supports the front end of the vehicle support plate at a position higher than the vehicle approach road surface so as to be movable up and down, and also supports the vehicle support plate at an inclined position where the rear end touches the vehicle approach road surface, and at an inclined position where the rear end touches the vehicle approach road surface. The parking system is made movable between the tip and a horizontal position that is approximately the same height. In addition, when the vehicle support plate is in an inclined position where its rear end touches the vehicle approach road surface, the intermediate portion between the front end side portion and the rear end side portion of the vehicle support plate is inclined with respect to the horizontal. The angle is smaller than the respective inclination angles of the leading end portion and the trailing end portion with respect to the horizontal.

This makes it possible to reduce the angle of inclination of the vehicle when the front wheels of the vehicle run onto the front end of the vehicle support plate from the rear end of the vehicle support plate, and the overall inclination angle of the vehicle support plate increases as the vehicle becomes more compact. However, the vehicle can be smoothly moved between the vehicle approach path and the vehicle support plate without the rear lower surface of the vehicle coming into contact with the vehicle approach path. Also, when the front wheels of the vehicle move to the tip side of the vehicle support plate, the slope of the vehicle increases;
By riding on the rear end side portion having the same inclination as the tip portion, the rear wheel is prevented from contacting the rear lower surface of the vehicle with the rear end side portion.

(Problem to be Solved by the Invention) After that, the vehicle that has run onto the vehicle support plate is moved to an inclined position for smooth exit from the garage and for safety against shaking in the event of an earthquake. If the vehicle is parked in a horizontal position, be sure to park the vehicle safely without accidentally backing up or falling off, and if parking the vehicle in a horizontal position, take care to ensure that the vehicle does not fall off due to shaking during an earthquake. is desired. If this is done using a special wheel stopper, the cost and inconvenience will increase due to the need for the wheel stopper and its attachment and removal. There may also be a danger of the car stopper coming off, or a problem of losing the car stopper.

Therefore, the present invention provides a parking system that can solve the above-mentioned problems by simply improving the position of the intermediate portion of the conventional vehicle support plate, which has a different inclination angle from the leading and rear end portions. The object of the present invention is to provide a vehicle support plate for the device.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following features:
The tip part is supported to be movable up and down at a position higher than the vehicle approach road surface, and has two positions: an inclined position where the rear end touches the vehicle approach road surface, and a horizontal position where the rear end is approximately at the same height as the front end. In the vehicle support plate of the parking device configured to be movable between The inclination angle is configured to be smaller than the respective inclination angles with respect to the horizontal of the front end side portion and the rear end side portion, and the intermediate portion is provided at a position where it can receive the rear wheel of a vehicle running onto the front end side portion. It is characterized by this.

(Function) According to the above configuration of the present invention, it is possible to reduce the inclination angle of the vehicle when the front wheels of the vehicle run onto the front end portion of the vehicle support plate from the rear end side portion of the vehicle support plate. Even though the inclination angle of can. In addition, when the front wheels of the vehicle move to the tip side of the vehicle support plate, the slope of the vehicle becomes large, but the rear wheels ride on the rear end side part that has the same slope as the tip, so that the rear lower surface of the vehicle increases. This avoids contact with the rear end side portion.

In particular, in the present invention, since the intermediate portion of the vehicle support plate is provided at a position where it can receive the rear wheel of a vehicle running onto the tip side portion, the parked vehicle can be parked so as to ride on the tip side portion of the vehicle support plate. Even if the rear wheels are supported at the intermediate portion and the vehicle is parked with the vehicle support plate left in an inclined position, the difference in slope between the intermediate portion and the front end portion acts as a stop for the rear wheels and provides for the vehicle. When used in conjunction with a handbrake, etc., it is possible to sufficiently prevent the vehicle from moving backwards spontaneously or accidentally due to shaking or vibration during an earthquake, and it is possible to park the vehicle with the vehicle support plate in a horizontal position. Even if the vehicle is subjected to shaking or vibration due to an earthquake or the like, it is possible to reliably prevent the vehicle from falling backward from the vehicle support plate.

(Example) Examples of the present invention will be described below with reference to the drawings. In FIG. 1, a board surface 2 is formed at a low position with respect to a vehicle approach road surface 1, and a frame 3 constituting the outer frame of a two-story parking device is formed on this board surface 2.
is installed. Further, the vehicle approach road surface 1 and the board 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, and a vehicle support plate 6 is provided 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, which are fixed to both sides of the frame 3 at an angle so that the rear end side is slightly lower. By being movably engaged with the inclined rail 9, the front end 7a is supported so as to be movable back and forth and movable up and down.
It is configured to also serve as a slope for moving the vehicle a in and out of the 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 of the chain 12 is suspended and supported. Further, on both sides of the frame 3, there are guide rails 13 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 as shown in the figure, and is provided with a multi-wheel type roller consisting of four or eight rollers that is movable along the guide rail 13. 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 both rear sides of the vehicle support plate 6 are connected to each other via the connecting rod 15, so that the vehicle support plate 6 can move into the parking space 5 when it is rotated up and down.
It is guided so that it does not swing in the width direction of a and 5b.
Also, the electric chain block 1 at the rear of the vehicle support plate 6
A tension spring 16 is actuated as necessary between the side edge opposite to the side where the vehicle supporting plate 6 is provided and the frame 3 above the side edge, and the tension spring 16 is actuated as necessary to reduce the force when the vehicle support plate 6 is raised and lowered on both rear sides. We are trying to alleviate the imbalance.

An inclined stepped portion 18 is formed at an intermediate portion between the front portion 7 and the rear portion 17 of the vehicle support plate 6 and is inclined downward toward the front portion 7 side. This inclined step part 1
8 is formed at a position where it can receive the rear wheels of the vehicle a running onto the vehicle support plate 6. Further, when the vehicle a is in a tilted state, let the inclination angle of the rear part 17 of the vehicle a with respect to the vehicle approach road surface 1 be θ ₁ , the inclination angle of the inclined stepped portion 18 be θ ₂ , and the inclination angle of the front part 7 be θ ₃ , θ ₂ <θ ₁ <
θ ₃ and θ ₂ is set to be an angle close to 0°.

Reference numeral 19 denotes a stopper provided at the vertically intermediate portion of the rear portion 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. 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 provided at the rear of the roof deck, and 23 is a cover portion extending from the bottom thereof. Reference numeral 24 denotes fall prevention bars horizontally installed above and below between the left and right links 10 to prevent the vehicle a from falling forward. This fall prevention bar 24 is a fixed one, but since the vehicle a does not need to advance forward from the position where the rear wheels are received by the inclined step 18, it will not be a particular hindrance. It can also be done.

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 an almost horizontal state,
It is locked with a stopper 19. In this state, when moving vehicle a into or out of the lower parking space 5b,
This can be done directly through the ramp surface 4 between the vehicle approach road surface 1 and the substrate surface 2. In addition, at this time, the vehicle support plate 6 that regulates the upper surface of the lower parking space 5b has a rear part 17 connected to the front part 7 through an inclined stepped part 18 in the middle thereof.
Since the vehicle a is located above the vehicle support plate 6, it does not interfere with the vehicle support plate 6 even when the vehicle a enters or exits the vehicle approach path 1 located above via the slope surface 4.

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. , return the vehicle support plate 6 on which the vehicle a is mounted to a substantially horizontal state. At this time, since the vehicle approach road surface 1 is at a higher position than the base plate surface 2, the vehicle support plate 6 can be returned to the above-mentioned substantially horizontal state simply by rotating the vehicle support plate 6 upward by a small angle. Furthermore, when rotating the vehicle support plate 6 in a substantially horizontal state, it can be brought into contact with the vehicle entrance road surface 1 by simply rotating it downward by a small angle, allowing the vehicle a to be smoothly moved in and out. Even if it is used, it is possible to avoid interfering with the vehicle a parked in the lower parking space 5b.

Furthermore, an inclined step portion 18 is provided at the intermediate portion of the vehicle support plate 6.
Therefore, when the vehicle support plate 6 is in the slope state, when the front wheels of the vehicle a move from the rear part 17 of the vehicle support plate 6 to the inclined step part 18, the inclination angle θ ₂ of this part with respect to the horizontal becomes the rear part. Since the inclination angle θ ₁ of 17 is smaller than 1, the inclination angle of vehicle a with respect to the horizontal can be made small, and the front wheels of vehicle a
By allowing the rear wheels to ride on the rear end of the vehicle support plate 6 when shifting to the vehicle a, it is possible to avoid 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 θ ₁ of the rear portion is smaller than the inclination angle θ ₃ of the front portion 7, there is an advantage that the vehicle a can be easily placed on the vehicle support plate 6.

Here, in order to smoothly exit the vehicle or for safety against shaking during an earthquake, the vehicle support plate 6 is left in an inclined position and the vehicle is parked safely without inadvertently backing up or falling off. By parking the vehicle in such a way that the rear wheels of the vehicle are supported by the sloped stepped portion 18 of the vehicle support plate 6 forming the slope, which is sloped so as to be locally nearly horizontal, the slope surface Since it has the effect of stopping the vehicle backwards compared to the vehicle that is parked on the slope, it is possible to firmly stop vehicle a by using it in conjunction with the handbrake installed in the vehicle. Retraction can be prevented without any special member.

In addition, when the vehicle is parked in a horizontal position with the vehicle support plate 6 in a horizontal position, the inclined step portion 18 is tilted forward and downward. Falling off can be reliably avoided.

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 rear part thereof rotates downward, and as a result, the vehicle support plate 6 is shortened and the inclination is increased, the vehicle can be placed in a sloped state without contacting the vehicle a parked in the parking space 5b at the bottom. This allows for a compact overall configuration.

Also, when raising the vehicle support plate 6, if the chain 12 of the electric chain block 11 is rolled up,
The vehicle support plate 6 follows the same route in reverse and returns to a substantially horizontal position, and similarly does not come into contact with the vehicle a in the lower parking space 5b. Also, in conjunction with the vertical movement of the vehicle support plate 6, the moving block 14
The moving block 14 moves the connecting rod 15 to the parking space 5.
By restricting the widthwise displacement of the parking spaces 5a and 5b, the vehicle support plate 6 is secured to the parking spaces 5a and 5b.
is prevented from swinging in the width direction, and even when one side of the vehicle support plate 6 is driven up and down by a single electric chain block 11, the vehicle support plate 6 is smoothly and safely raised and lowered.

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 is of course possible to use other lifting means such as a fluid cylinder device.

(Effects of the Invention) According to the present invention, it is possible to reduce the angle of inclination of the vehicle when the front wheels of the vehicle run onto the front end portion of the vehicle support plate from the rear end side portion of the vehicle support plate, and the vehicle support plate can be Even though the inclination angle increases as a whole, the vehicle can be smoothly moved between the vehicle approach road and the vehicle support plate without the rear lower surface of the vehicle coming into contact with the vehicle approach road, When the front wheels of the vehicle move to the front end of the vehicle support plate, the slope of the vehicle increases, but the rear wheels ride on the rear end, which has the same slope as the front end, so that the rear lower surface of the vehicle Since contact with the rear end side part is avoided, 1
Parking of two vehicles can be achieved using one parking space without compromising easy and safe access of vehicles.

Particularly, in the present invention, the intermediate portion of the vehicle support plate is provided at a position where it can receive the rear wheels of a vehicle riding on the tip side portion, and the parked vehicle can be parked so as to ride on the tip side portion of the vehicle support plate. Even if the vehicle is parked with the wheels supported at the intermediate portion and the vehicle support plate left in an inclined position, the vehicle acts as a rear stop for the rear wheels due to the difference in slope between the intermediate portion and the front end portion; When used in combination with a handbrake, etc. installed in the vehicle, it is possible to sufficiently prevent the vehicle from rolling backwards naturally or due to the effects of shaking or vibrations such as an earthquake, without special parts or handling. Even if the vehicle is parked with the vehicle support plate in a horizontal position and subjected to shaking or vibrations caused by an earthquake, it is possible to reliably prevent the vehicle from falling backward from the vehicle support plate, reducing the complexity and cost of the structure. To safely achieve convenient parking with the vehicle support plate tilted without seeing the vehicle rise, or parking with the vehicle support plate horizontal.
