[Problems to be solved by the invention]
However, the above-described multi-level multi-story parking facilities have the following problems.
[0008]
First, a description will be given with reference to a cross-sectional view of the multi-story parking facility shown in FIG.
As described above, for example, the opening of the entrance and exit of the vehicle on the wall 114 that covers the multi-story multi-story parking facility with one story underground and two stories above ground is generally designed to have a size of about 2700 to 2800 mm due to its structure. Yes (h₁). In addition, when the safety fence 112 is at the highest position at the entrance and exit of the vehicle, the height of the opening of the entrance and exit (h in the figure)₂) Is determined to be 1800 mm or more. Therefore, the height of the safety fence 112 (h in the figure)₃) Is 900 to 1000 mm. Further, in a state where the safety fence 112 is lowered, for example, when the safety fence is lowered until the lower surface of the safety fence comes into contact with the reference surface 111, the height of the safety fence 112 from the reference surface 111 (h in the figure)₄) Is 900 to 1000 mm in height of the safety fence 112. However, at a height of 900 to 1000 mm, the height is such that a person can easily get over the same. Therefore, the height from the upper surface of the safety fence 112 to the reference surface 111 (h in the figure)₄) Requires about 1500 mm. As a result, between the lower surface of the safety fence 112 and the reference surface 111 (h in the figure)₅) Has a gap of about 500 to 600 mm.
[0009]
On the other hand, if the width of the safety fence 112 is set to about 1500 mm in order to prevent this gap from being generated, when the safety fence 112 is raised, the distance from the lower end of the safety fence to the reference surface 111 (h in the figure)₄) Becomes 1800 mm or less, which hinders people from entering and exiting the multi-story parking facility and from entering and exiting the vehicle.
