Abstract
An apparatus includes a fixed plate 902 mounted in a bed cabinet 108 and a rotating plate 904, mounted to a bed frame 106, coupled to the fixed plate 902 at a pivot point 906. A first end of a first lever arm 918 is coupled to the fixed plate 902. A first end of a second lever arm 920 is coupled to the first lever arm at a point between the first end and the second end of the first lever arm 918. The second end of the second lever arm 920 is coupled to the rotating plate 904 at a position that is offset a horizontal distance from the pivot point 906. A first end of a gas spring 908 is coupled to the fixed plate 902 and the second end of the gas spring 908 is coupled to the second end of the first lever arm 918.

A bed moving apparatus comprising:
- a fixed plate mounted on a vertical wall of a bed cabinet;
- a rotating plate rotatably coupled to the fixed plate at a first pivot point, the rotating plate mounted to a bed frame, wherein when the bed frame is in a vertical position the rotating plate is approximately parallel to the fixed plate, and when the bed frame is in a horizontal position the rotating plate is approximately perpendicular to the fixed plate;
- a first lever arm comprising a first end and a second end, the first end of the first lever arm rotatably coupled to the fixed plate;
- a second lever arm comprising a first and a second end, the first end of the second lever arm rotatably coupled to the first lever arm at a point between the first end and the second end of the first lever arm, and the second end of the second lever arm rotatably coupled to the rotating plate at a position that is offset a first horizontal distance from the first pivot point;
- and
- a gas spring with a first end and a second end, the first end of the gas spring rotatably coupled to the fixed plate and the second end of the gas spring rotatably coupled to the second end of the first lever arm, the gas spring opposing a gravitational force acting on the bed frame as the bed frame moves from the horizontal position to the vertical position.
