Such a device as described above is known and often practiced as a tandem type facility having one or two entrances and exits of a vertical circulation parking device.

[Problems to be solved by the device]

Although such a device has been widely used, it has a drawback in terms of users.

As is clear from the figure, since the flaps are used to absorb the step, there is a point that rolling on the ups and downs of the oblique road on the flaps is required for loading and unloading. That is, in the case of FIG. 6, when entering the parking device on the far side, the flap must be descended obliquely to enter, and when exiting,
The flaps have to be lifted up in the retracted position before leaving. Alternatively, in the case of FIG. 7, when using the parking device on the back side, when entering, when exiting when using the parking device on the front side, the valley-like undulations between the flaps must be sloped up and down. I have to.

Such ups and downs force a driver entering and leaving the vehicle to perform careful driving, which is not preferable from the viewpoint of comfort of use. Alternatively, depending on the type of vehicle with a low floor, there is a possibility that the vehicle lower surface may collide with the vehicle passage portion of the flap and be damaged.

Therefore, there has been a demand for a column-type vertical circulation parking device that does not have such flap ups and downs and that has excellent usability on a flat surface and that can be loaded and unloaded.

The present invention was made to improve the situation as described below.
It is an object of the present invention to provide an apparatus for allowing a vehicle to be loaded and unloaded through a substantially flat aisle or running path with little undulation in a vertical type vertical circulation parking apparatus.

A tandem vertical circulation parking device configured to form a passage for entering or leaving a vehicle to or from another vertical circulation parking device, in which a pit is dug under the vertical circulation parking device to be the passage. At the same time, it is provided with a sliding floor capable of opening and closing the pit in a horizontal direction perpendicular to the front-rear direction and a driving means for moving the sliding floor, and the sliding floor is in an open state. When When the pit of the vertical circulation parking device to be the aisle is opened so that the cage can circulate and land, and the sliding floor is closed, a suspension for one car is not provided above the pit. The space portions corresponding to each other are positioned so as to form a traveling path for the automobile to travel, and the sliding device opposes a pair of horizontally displaceable sliding floors facing each other. A pair of sliding floors are provided, and each sliding floor has a protrusion capable of being interlocked and pulled by engaging with a protrusion of the adjacent sliding floor at the end in the horizontal direction. It is configured as a sliding floor device of a tandem vertical circulation parking device that forms a guide flange that defines a course of an automobile that enters and leaves when closed.

[Action]

The sliding floor device of the present invention is a vertical circulation parking device that constitutes a vertical vertical circulation parking device, and is a vertical circulation parking device that serves as a passage for a vehicle to enter or leave another vertical circulation parking device. It is provided under the shaft of the device.

Further, the pit is provided with a driving means such as a chain attachment, and each of the pair of sliding floors is connected to the driving means and can move toward and away from each other.

Now, when the driving means is driven in the forward direction, for example, the pair of sliding floors move closer to each other from below the side plates due to the above-mentioned connection, and further pull the other sliding floors in order to close the top of the pit. However, the upper surface of the sliding floor forms a substantially flat traveling path of the automobile.

When the driving means is driven in the opposite direction, for example, each of the pair of sliding floors moves far away in the anti-reverse direction due to the above-mentioned connection, and the other sliding floors are sequentially pulled to be housed under the side plates on both sides. Opens. Therefore, the cage of the parking device, which should be a passage, can be circulated and the landing can be stopped.

However, depending on the installation condition, if the left and right side plates 16a and 16b have a sufficient margin, each of the left and right sides 1 and 2 can be configured to appear on the left and right with the same configuration as the above device.
It is also possible to configure a sliding floor device having a total of two sheets by using a sliding floor addressed to one sheet.

Further, in the above-mentioned embodiment, the case of the parallel parking system having one entrance / exit has been described, but as shown in FIG. 7 (a) (a) used in the description of the conventional technique,
In the case of a so-called through-type device having an entrance and an exit, the sliding floor device is installed in each of the first parking device and the second parking device, and each of them is installed as a set. It can also be equipped so that the pit can be opened and closed.
Further, when a plurality of two or more units are arranged in a column, it is also possible to arrange and use them in each parking device portion as needed.

[Advantage of the Invention] The vertical circulation parking device of the column type is effective for efficiently utilizing a long and narrow land to secure a large number of parking lots, and
It is used a lot. However, in the conventional device of this type, the car to be used had to pass the undulation of the flap for absorbing the step difference in the pit ascending or descending. For this reason, the driver of the car must drive carefully and carefully, resulting in poor availability and convenience,
In addition, the time required for loading and unloading is generally long, resulting in poor utilization efficiency. Further, particularly in the case of an automobile having a low floor, the longitudinal inflection point of the flap may come into contact with the lower surface of the automobile to cause scratch damage.

The sliding floor device of the present invention uses a sliding floor that moves in and out in a horizontal direction. When the sliding floor is opened, the pits necessary for circulation of the cage can be opened and the sliding floor can be opened. When the vehicle is closed, a substantially flat automobile passage is formed.

As a result, the burden on the motor vehicle driver in the case of loading and unloading a vertical vertical circulation parking device is reduced, and the usability is improved. Along with this, the average required time for warehousing and unloading is shortened, and the risk of damage to the bottom surface of a low-floor automobile is eliminated.

In the case of using the sliding floor having the four-layer structure shown in the embodiment, the wheels of the vehicle are guided straight ahead if the distance between the small steps due to the protrusions 24, 24 is appropriately determined. The function of the guide flanges 39, 39 for operating can be retained.
