Claims

[Scope of utility model registration request]

A fixed frame fixed to the lower surface of a heavy object, a movable frame fitted to the fixed frame so as to be movable up and down with its lower part protruding, and a fixed frame separated from each other in the horizontal direction. a movable member supported by the body and protruding downward from the fixed frame; and a moving member that is separated from each other in the horizontal separation direction in one of the fixed frame and the movable frame and is substantially perpendicular to the separation direction. It has a rotating shaft that extends and is supported by the frame, extends from the rotating shaft outside the frame along the frame, and is rotatable from a substantially horizontal position in the upright direction. a lever device having a long operating section and a short operating section provided inside the frame in a direction substantially perpendicular to the operating section from the rotation axis; the fixed frame and the movable lever device; a spring for raising the movable frame so that both ends are supported by the frame so that the lower end of the movable frame is above the lower end of the moving member; and a spring fixed to the other of the two frames. As the acting part rotates, the movable frame is pushed down by the contact pressure with the acting part, and the lower end of the movable frame is moved from a position above the lower end of the moving member to a position below or at the same height. A support structure for moving a heavy object, comprising: a pressure receiving part arranged to move the object; and a detent mechanism for releasably holding the movable frame in the lower position.
