Claims

[Scope of utility model registration request]

A bed floor plate support frame, a pair of lower support bases fixed vertically downward to opposing side frames of this support frame, a rotating rod horizontally fixed between the pair of lower support bases, an actuating arm fixed to an intermediate portion of the rotating rod; one end connected to the free end of the actuating arm;
In a bed floor plate support frame tilting device comprising a telescoping rod whose other end is fixed to the floor plate support frame, and an operating switch connected to the telescoping rod via an operating wire, the telescoping rod is connected to a cylinder body; The cylinder body has a protruding piston rod with a push rod at its tip, which extends outward from the tip of the cylinder body, and is rotatably connected to the free end of the operating arm at the distal end of the cylinder body, and the piston rod has a protruding piston rod at its tip. The push rod is fixed to the horizontal frame of the floor plate support frame, and a trigger lever is rotatably disposed near the protruding tip of the push rod, and an operating rod is rotatable between the opposite side frames of the floor plate support frame. The operating switch is freely suspended horizontally, and has an operating piece attached to at least one end of the operating rod, and a fixed piece fixed to the intermediate portion at right angles to the operating rod. a pressing rod having a pressing protrusion at its inserted tip; the pressing rod is fixed to the floor plate support frame so that the pressing protrusion contacts or comes close to the operating piece of the operating rod, and the operating wire has one end attached to the operating rod. The other end of the fixed piece is connected to a trigger lever, and when the pressing rod is pressed, the pressing projection protrudes and the operating piece is pressed.
This pressure causes the operating rod to rotate and the operating wire to be pulled, simultaneously rotating the trigger lever.As the trigger lever rotates, the push rod is pressed by the trigger lever and the telescoping rod is extended. A bed floor plate support frame tilting device characterized in that the support frame is lifted and tilted.
