【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

The basic structure of the multi-storey car park is as described in the section of the prior art with reference to FIG. 1 and FIG. 2, and the doorway 8 provided at the lower center position on the front center of the main frame 1 is The upper horizontal beam 21 and the vertical columns 22 and 22 on both sides supporting the upper horizontal beam 21 are formed into an opening having a size large enough for an automobile and a person to pass through. It is installed in the central part of.

As shown in FIGS. 3 and 4, the shutter 9 is formed by using a horizontally long channel material or the like so as to be housed between the vertical columns 22 and 22, and the shoes 24 and 24 fixed to both ends thereof are vertical columns. It is held by 22 and 22, and the vertical movement is guided along the vertical columns 22 and 22.

The hoisting device 23 is formed by providing a winding drum 27 that winds the two wires 26, 26 on an output shaft of a motor 25 fixed to the upper horizontal beam 21, and in opposite directions from the drum 27. The wires 26, 26 drawn out to the above are guided downward by the pulleys 28, 28, and the tip ends of the wires 26, 26 suspend and support the positions near both ends of the shutter 9, and the shutter 9 is rotated horizontally by the forward and reverse rotation of the motor 25. It is designed to move up and down.
