Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a safety device for an automatic door in a mechanical multilevel parking facility, such as a multi-level, flat circulation parking facility.

(Prior Art) Conventionally, as shown in FIGS.
An arbitrary number of wheeled trays 2 to be placed are combined in multiple rows (two rows in the figure) and in multiple layers (two underground layers in the figure), and a dead space equivalent to one tray is formed at the upper end of each plane diagonal. , a parking device configured such that a vertical feeding device 3 is provided in the column direction, and a lateral feeding device 4 is provided in the horizontal feeding direction, and the respective trays are moved and circulated in a two-step system by the operation of both feeding devices. The equipment units 5 are arranged vertically, for example, in two underground layers, and a forklift 6 is installed on either side of each layer.

Next, in the parking facility, the car 1 entering from the entrance 7 is placed on the tray 2 on the lifting frame 8 of the forklift 6, and as the lifting frame is lowered, it reaches the level of the parking unit 5 on the second underground floor. After being moved laterally by the transverse feeder 4 and placed on the moving rail 10 attached to the chain belt 9, it is vertically moved to a dead space by the vertical feeder 3, and placed at a predetermined location by the transverse feeder. It is ordered to be stocked.

(Problem that the invention attempts to solve) Recently, a driver made a driving mistake and crashed into the closed auto door 11 installed at the car entrance 7, destroying the door and leaving the car with the driver. There have been cases where cars have fallen into pits and broken, resulting in personal accidents, and there is an urgent need to take safety measures to prevent such accidents.

(Means for Solving the Problem) Therefore, according to the present invention, a balance weight attached to a wire hanging an auto door that is movably installed in the front of a car lift room of a mechanical multilevel parking facility and The door is connected to a barrier having a parallelogram link mechanism installed near the back side of the door by a connecting wire, and the barrier is raised and lowered by closing or opening the door.

(Embodiment) As shown in FIG. 4, the auto door 11 is installed in the front inner side (standing side) of the car lift room 13 where the forklift 6 ascends or descends the hoistway 12 so as to be able to open and close or move up and down. As shown in Figures 2 and 3, there is a
The book hoisting wires 14 and 15 are connected to the wall 16 as appropriate.
Wire sheaves 17, 18, 1 fixed to
As shown in FIG. 1, guide rails 21 are provided on both sides of the automatic door, and these guide rails are connected to the front wall 22, It fits into door rails 23, 23 embedded in 22 and is guided up and down.

In addition, a barrier 25 having a parallelogram link mechanism is disposed in a pit 24 dug near the back side of the automatic door 11, and the barrier has a pair of opposing rockers pivotally installed at the bottom of the pit. It is composed of movable arms 26, 26 and a movable rod 27 pivotally attached to the ends of these arms, and one end of the movable rod is connected to a hanging fitting 28 attached to the balance weight 20 by a connecting wire 29. be.

(Function) In the device of the present invention having the above-mentioned configuration, when the automatic door 11 is raised for loading/unloading by an appropriate lifting means (not shown), the steps shown in FIGS.
The balance weight 20 shown in the figure is lowered, and the movable rod 27 of the barrier 25 is moved counterclockwise.
The position shown by the dotted chain line is reached, and the vehicle is ready for entry and exit. When the entry and exit operation is completed and the auto door 11 is lowered by the driving means, the lifting wires 14 and 15, the balance weight 20, and the connecting wire 29 move in the direction of the arrows, and the movable rod 27, which had been in the position shown by the two-dot chain line, moves to the swing arm 2 to which the joint is connected.
6 and 26 rotate clockwise, they move clockwise to the solid line position, and the barrier 25 of the parallelogram link mechanism is in the position shown by the solid line, and at the same time, the auto door is completely landed or closed. .

(Effect of the invention) In such a door closed state, according to the invention, even if the car collides with the automatic door 11 due to a driver's driving error and the door is destroyed, the car will not stop because it hits the barrier 25. Since the barrier does not fall into the pit, there is no possibility of personal injury, and since the barrier is installed near the back of the automatic door, the depth of the car lift room can be reduced, making it possible to make the multilevel parking equipment or building more compact. At the same time, since the space in front of the auto door can be widened, the automobile on the turntable can be operated safely and easily.
