Claims

[Scope of claims for utility model registration] (1) It can be raised and rotated using the proximal end as a fulcrum;
It is a stage that can be used in a reclined state and stored in an upright state, and has a plurality of stay dampers that are rotatably connected to the fixed side and the stage side in the backstage area, each consisting of a cylinder filled with high-pressure gas. Some of the stay dampers in this stay damper group have one end connected to the stage side and the other end connected to a fixed side to constantly load the stage and support the upright state. The other end of the other stay damper connected to the stage side or the fixed side is connected to the connecting piece attached to the stage side or the fixed side in a no-load state, and each connecting piece is connected to it at a position corresponding to the stage's inclination angle. The stay dampers are arranged so as to be coupled to the other ends of the connected stay dampers, and the rotational fulcrum of the stay damper group is located inside and below the stage's lodging rotational fulcrum, and the other stay dampers are sequentially moved in accordance with the stage's lodging angle. A labor-saving device for raising and lowering a stage that operates only when it receives the stage load for the first time. (2) The labor-saving raising and lowering device for a stage according to claim 1, in which the other end of another stay damper is connected with a pin through a long hole of a connecting piece fixed to the stage side or fixed side. (3) Utility model registration claim 1, in which the other end of another stay damper is connected with a pin to one end of a link connecting piece rotatably attached to the stage side or fixed side.
A labor-saving raising/lowering device for the stage described in Section 1.
