Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for parking vehicles such as automobiles.

(Prior Art) A multi-level parking system is known that can park two vehicles, one each on an upper and lower level, using a lift in a flat space for one vehicle.

(Problem that the invention aims to solve) In the conventional lift method, when a vehicle parked on the upper tier is loaded or unloaded on a lift, the lower tier vehicles parked under the lift must be evacuated before lowering the lift. This poses a problem in that it is inconvenient to use.

Japanese Patent Publication No. 38-13280 and Japanese Utility Model Application Publication No. 47-30281 disclose parking devices that solve the above problem.

In the vehicle described in the above publication, a vehicle support plate supported in a seesaw shape is provided at the boundary between the upper and lower parking spaces. The vehicle support plate is connected to a lifting means and is moved up and down between a horizontal position where the vehicle is held in the upper parking space and a sloped state where the rear end is in contact with the vehicle entry road surface, and the base surface of the lower parking space is raised and lowered. It is lower than the vehicle entrance road surface, and both are connected by an inclined surface.

However, in such a structure, the vehicle support plate is supported in a seesaw shape, so when a vehicle that has run over is supported in the upper parking space in a horizontal position, the weight of the vehicle is distributed in front and behind the vehicle support plate. This distribution effect causes the vehicle support plate to wobble, and in order to stably hold it, the elevating means needs to be strong, making it expensive and increasing the size of the device. Further, since the vehicle support plate is tilted to the slope position by pivoting around the pivot point in the middle, it is unlikely to interfere with vehicles parked in the lower parking space. However, since the pivot point is closer to the rear from the tip of the vehicle support plate, the required slope becomes steeper for the rear end of the vehicle support plate to be in the slope position where it touches the vehicle approach road surface. Although the support height of the vehicle support plate is closer to the vehicle approach road surface due to the fact that the base surface of The rear part of the vehicle tends to rub against the vehicle entrance road surface, and the only way to solve this problem is to increase the parking space and reduce the required slope of the vehicle support plate, which leads to an increase in the size of the device.

Furthermore, the structure shown in FIG. 2 of the latter publication is one in which the vehicle support plate is pivoted at the front end, and the problems encountered with the seesaw-type support structure are solved. However, although the vehicle support plate is tilted to the slope position, it can contact the vehicle approach road surface with a small degree of inclination, but this tends to interfere with vehicles parked in the lower parking space. Therefore, in order to solve this problem, as shown in FIG. 2, if the lower parking space is extended further forward than the upper parking space, this will result in an increase in the size of the entire device. If this structure is replaced with a steeper inclination at the slope position of the vehicle support plate, the problem arises that the rear part of the vehicle rubs against the vehicle entrance road surface.
Furthermore, as disclosed in FIG. 1 of the above-mentioned later publication, it is also possible to provide vehicle support plates for each of the upper and lower parking spaces, but the structure becomes complicated and the cost increases accordingly.

Therefore, an object of the present invention is to provide a parking device that has a simple structure and can solve the various problems mentioned above.

(Means for Solving the Problems) In order to solve the above problems, the present invention pivots the tip of the vehicle support plate around a pivot located at a high position relative to the vehicle entry road surface, and A lifting means is provided to rotate the plate between a slope position where the rear end touches the vehicle approach road surface and a substantially horizontal position, while a base surface is provided at a low position with respect to the vehicle approach road surface, and the vehicle approach road surface is The road surface and the base surface are connected by a slope surface, and at the slope position of the vehicle support plate, the inclination angle with respect to the horizontal in the middle part in the longitudinal direction is made smaller than the inclination angle with respect to the horizontal in the front end side part and the rear end side part. This is a characteristic feature.

(Function) According to the above configuration, by rotating the vehicle support plate up and down by the lifting means around the pivot point at the tip, the vehicle is placed in a horizontal position where the vehicle is supported in the upper parking space, and the rear end is rotated up and down. Since the vehicle is moved appropriately to the slope position where it touches the vehicle approach road surface and the vehicle can enter, the direction in which the weight of the vehicle acts does not change even with this movement, so it can be easily stabilized at each moving position. can. In order to move to the slope position, the vehicle support plate is tilted by rotation at the front end pivot point, and the vehicle approach road is connected to the base surface of the lower parking space and the slope surface so that vehicles can enter and exit. By being located higher than the base surface,
The vehicle support plate can be grounded on the vehicle approach road surface with a small slope, and the degree of interference with vehicles parked in the lower parking space can be reduced.

In addition, the vehicle support plate has a tilt angle with respect to the horizontal at the middle part at the slope position that is smaller than the tilt angle with respect to the horizontal at the front end and rear end sides, so that the vehicle may run onto the front end of the vehicle support plate. By making the inclination of the vehicle smaller than the inclinations of the leading and rear end portions of the vehicle support plate, it is possible to alleviate the friction of the rear end of the vehicle with the vehicle entry road surface due to the inclination of the vehicle support plate. .

(Embodiment) In the first embodiment of the present invention shown in FIG. 1, a base surface 5 is provided at a low position with respect to the vehicle approach road surface 1, and a two-story parking device is constructed on this base surface 5. be. The vehicle entrance road surface 1 and the base surface 5 are connected by a slope surface 18.

The frame 8, which is formed in the shape of a rectangular frame, has a space above and below in which two vehicles a can be parked, and a vehicle support plate 3 is installed at an intermediate height on the front side (right side in Figure 1). A pivot 2 is provided to rotatably support the tip 4. . It goes without saying that this pivot 2 is located at a high position with respect to the vehicle approach road surface 1.
The vehicle support plate 3 is moved from an inclined position A (solid line in FIG. 1) where the rear end 6 touches the vehicle entrance road surface 1 to a horizontal position by an elevating means 7 attached near the rear end 6 to a horizontal position where the rear end 6 is approximately horizontal. It is rotated between position B (phantom line in FIG. 1).

In this embodiment, the elevating means 7 includes a drive motor 9, a drive shaft 10 extending from the drive motor 9 to both sides, a pair of left and right hoist wheels 11, 11 fixed to both ends of the drive shaft 10, and each hoist. It consists of a hoisting rope 12 wound around a ring 11, and the lower ends of these hoisting ropes 12, 12 are attached to both sides of the rear end 6 of the vehicle support plate 3. The vehicle support plate 3 is rotated from the inclined position A to the horizontal position B by the operation of the drive motor 9. When it reaches the horizontal position B, it is held at that position by the stopper device 13. In order to return the vehicle support plate 3 to the inclined position A, it is sufficient to disengage the stopper device 13 and rotate it downward under its own weight. It is preferable to configure this. At the inclined position A, the rear end 6 of the vehicle support plate 3 is in contact with the vehicle entrance road surface 1 and stands still, so there is no need to provide any special position holding means. Note that 14 is a switch for remotely controlling the drive motor 9.

The vehicle support plate 3 is formed to have enough rigidity and strength to support the vehicle a, and is formed in a shape as shown in FIG. That is, when the vehicle support plate 3 is in the inclined position A, the central portion 1
The inclination angle θ1 with respect to the horizontal of 5 is the tip side portion 17
The vehicle support plate 3 is formed so as to be smaller than the inclination angles θ3 and θ2 of the rear end side portion 16 with respect to the horizontal, respectively. For example, θ1=0°, θ2=10°, θ3
= 15°. Forming the vehicle support plate 3 in this manner has the advantage that when the vehicle a gets on the vehicle support plate 3 at the inclined position A, the lower surface of the rear end of the vehicle a can be prevented from coming into contact with the vehicle approach road surface 1. In addition, the inclination angle θ2 of the rear end side portion 16 is
It has the advantage that it can be made gentler and the vehicle a can be easily placed on the vehicle support plate 3. It is preferable to form the upper surface of the vehicle support plate 3 into an uneven surface to prevent slipping, and it is also optimal to attach a stopper device (not shown) on the vehicle support plate 3 to prevent the vehicle a from moving backward.

Next, how to use the above embodiment will be explained. In order to park the vehicle a on the vehicle support plate 3 of the parking device, the vehicle support plate 3 is rotated downward and set to the inclined position A shown by the solid line in FIG. This connects the vehicle approach road surface 1 and the vehicle support plate 3, so that the vehicle a can drive onto the vehicle support plate 3 from the vehicle approach road surface 1. Furthermore, since the vehicle approach road surface 1 is located at a higher position than the base surface 5, the vehicle support plate 3 can be rotated at a small rotation angle without rotating the vehicle support plate 3 downward to the angle where the rear end 6 is installed on the extension surface of the base surface 5. The vehicle support plate 3 can be connected to the vehicle approach road surface 1. As a result, the slope of the vehicle support plate 3 in the inclined position can be made gentler, so that the vehicle a between the vehicle approach road surface 1 and the top of the vehicle support plate 3 can be
can be easily moved. In addition, since the rotation angle of the vehicle support plate 3 that rotates downward is small, the base surface 5
It is possible to avoid the vehicle support plate 3 from coming into contact with the vehicle a parked above. As a result, the vehicle a can be parked on the upper vehicle support plate 3 without having to take or take out the vehicle parked on the lower base surface 5. Note that it is preferable to set the height difference H between the vehicle approach road surface 1 and the base surface 5 to approximately 300 mm in the case of a light four-wheeled vehicle and approximately 550 mm in the case of a medium-sized vehicle.

Next, as shown by the imaginary line in FIG. 1, the vehicle support plate 3 is rotated upward to the horizontal position B, and the vehicle a is parked on the upper stage of the device. It is safe and suitable for labor saving to perform this work when the driver gets off the vehicle a, but it is also possible to perform this work while the driver remains in the vehicle. The vehicle a can be parked on the lower base surface 5 by driving from the vehicle approach road surface 1 through the slope surface 18 onto the base surface 5 with the vehicle support plate 5 set in the horizontal position B. .

In the second embodiment of the present invention shown in FIG. 2, the pivot shaft 2 at the tip 4 of the vehicle support plate 3 is guided and supported by a pair of inclined rails 19 on both sides so as to be movable back and forth. The foldable link 2
0 to frame 8.

The tip 4 of the vehicle support plate 3 is connected to a pair of guide rollers 2 attached to both ends of the pivot shaft 2, as shown in FIG.
1 and 21, it is guided and supported so as to be movable back and forth by inclined rails 19 and 19, each having a U-shaped cross section, which are fixed to both sides of the frame 8. Further, the tip portion 4 is connected to the pivot shaft 2.
It can be rotated through. This inclined rail 19 is installed so that the height position of the rear part is lower than that of the front part. Further, the tip portion 4 is connected to the front side of the frame 8 at an intermediate height position via a pair of foldable links 20, 20. Incidentally, fall prevention bars 22, 22 are installed horizontally above and below between the links 20, 20 to prevent the risk of the vehicle a falling forward. On the other hand, a hoisting rope 12 of the elevating means 7 is attached to the rear end 6 of the vehicle support plate 3 at an inclination angle θ, as shown in FIG. This angle of inclination θ generates a component force F1 that urges the vehicle support plate 3 forward (to the right in FIG. 2). The rest of the configuration of this embodiment is the same as that of the first embodiment.

According to the above configuration, when the vehicle support plate 3 is at the horizontal position B as indicated by the imaginary line in FIG. The component force F2 in the direction of the inclined rail 19 applied to the guide roller 21 is balanced, and the vehicle support plate 3 is stationary. The rear end 6 of the vehicle support plate 3 is moved from the horizontal position B to the inclined position A shown by the solid line in the figure.
When the hoisting rope 12 is lowered, the inclination angle θ of the hoisting rope 12 becomes smaller. . Along with this, the component force F1 that urges the vehicle support plate 3 in the forward direction gradually weakens, so that the vehicle support plate 3 is forced toward the vehicle approach road surface 1 in order to restore balance with the component force F2 applied to the guide roller 21. Move forward. By setting the vehicle support plate 3 to the inclined position A in this manner, the vehicle a can drive onto the vehicle support plate 3 from the vehicle approach road surface 1.

In this embodiment, when the vehicle support plate 3 rotates downward, the vehicle support plate 3 moves forward, and when the vehicle support plate 3 rotates upward, the vehicle support plate 3 moves back and forth.
Compared to the embodiment, the longitudinal dimensions of the vehicle support plate 3 can be made more compact.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, as the elevating means 7, a power device using a chain, a rack and pinion, etc. can be used, and a manual chain block or the like can also be used. Furthermore, the concept of grounding in the present invention is not limited to the case where the rear end portion 6 of the vehicle support plate 3 directly contacts the vehicle approach road surface 1, but also when a gap is formed between the rear end portion 6 and the vehicle approach road surface 1. Of course, this also includes cases where the vehicle a is within a range where vehicle a can pass smoothly.

(Effect of the invention) According to the invention, by rotating the vehicle support plate vertically around the pivot point at the tip using the lifting means, the vehicle can be placed in a horizontal position where the vehicle is supported in the upper parking space, and at the rear end. Since the vehicle is moved appropriately to the slope position where the part touches the vehicle entrance road surface and the vehicle can enter, the direction of action of the vehicle weight does not change even with this movement, so it can be easily stabilized at each moving position. This makes it possible to simplify the elevating means and reduce the cost and size of the device.

In order to move to the slope position, the vehicle support plate is tilted by rotation at the front end pivot point, and the vehicle approach road is connected to the base surface of the lower parking space and the slope surface so that vehicles can enter and exit. By being located at a higher position than the base surface, the vehicle support plate can be grounded to the vehicle approach road surface with a small slope, and the degree of interference with vehicles parked in the lower parking space is reduced. In addition, the slope angle of the vehicle support plate with respect to the horizontal in the middle part at the slope position is smaller than the slope angle with respect to the horizontal of the front end side part and the rear end side part, so that the vehicle is the inclination of the vehicle when it runs over the part,
By making the inclination smaller than that of the leading end and rear end of the vehicle support plate, it is possible to reduce the friction between the rear end of the vehicle and the vehicle entry road surface due to the inclination of the vehicle support plate, so that the slope between the vehicle support plate and the lower part can be reduced. The inclination of the vehicle support plate can be increased to avoid problems such as interference with parked vehicles in the parking space, friction with the vehicle approach road surface at the rear of the vehicle, or raising the height of the tip of the vehicle support plate. By moving the ground contact position closer to the front end side, the device can be made smaller both in the longitudinal direction and the height direction, making it possible to save space and further reduce costs.
