ようにしていた。(Prior Art) Conventionally, as shown in Fig. 5, this type of ceiling folding staircase has been designed to prevent it from falling due to its own weight when opening the ceiling cover a.
Alternatively, the ceiling Ma is biased upward by a gas spring b to facilitate the work when closing the ceiling cover a. The installation of the gas spring b is carried out after the base end of the gas spring b is pivotally supported on the mounting plate C attached to the upper surface of the ceiling cover a when the ceiling Ma is in a closed state closed to the ceiling frame e. The rod end of spring b is shown in Figure 6 (al~(
After connecting and fixing the connecting part to the mounting bracket f fixed to the side surface of the ceiling frame e as shown in C), tighten the bolt g of the mounting bracket f to connect the connecting part to the arrow Q shown in Figure 6(b). By moving the rod end of the gas spring b in the direction and retracting the rod end of the gas spring b, and pressurizing the gas spring b, a force is exerted to pull the ceiling cover a upward even when the ceiling cover a is closed.

（発明が解決しようとする問題点）
しかしながら、上記従来の方法では次のような問題があ
った。(Problems to be Solved by the Invention) However, the above conventional method has the following problems.
■ ロッド端と連結する取付金具の連結部を移動可能な
構造にしなければならず、取付金具の構造が複雑になり
製造コストが高くつく。■ The connecting part of the mounting bracket that connects to the rod end must be constructed to be movable, which complicates the structure of the mounting bracket and increases manufacturing costs.
■ 取付金具の連結部はボルトを締めることによって移
動されるため、天井裏等の作業スペースの狭い所ではボ
ルト締めに手間がかかり作業性が悪い。■ The connecting parts of the mounting brackets are moved by tightening the bolts, so tightening the bolts is time-consuming and difficult to work in places with narrow working spaces, such as in the ceiling.
■ 取付金具のボルトを締め忘れることでガススプリン
グが正常に作用せず、取付不良の原因となる。■ If you forget to tighten the bolts on the mounting bracket, the gas spring will not work properly, resulting in poor installation.

くなる。First, as shown in FIG. 2, the ceiling M2 is pushed up toward the ceiling, and the ceiling cover 2 is moved above the closed position where it is normally closed. Then, the gas spring 5 in the free state is The base end portion 6 is pivotally supported on the mounting plate 8, and
The rod end 7 is connected to the mounting bracket 10. Thereafter, as shown in FIG. 3, the ceiling M2 is rotated downward around the pivot 8a to the closed position, and a stopper is installed in the ceiling frame 1 to prevent the ceiling M2 from rotating upward from the closed position. Install 11. At this time, since the pivot portion 8a of the mounting plate 8 is also rotated as the ceiling M2 is rotated, the rod of the gas spring 5 is retracted more than when it was first installed, and the gas spring 5 is thereby applied. be pressured. Therefore, the ceiling M2 is urged upward with an appropriate force in the closed position. This upward biasing force is the ceiling M2 when installing the gas spring 5.
determined by the upward tilt angle of In other words, the greater the inclination angle, the greater the biasing force when the ceiling cover 2 is closed.
