ABSTRACT:
The bed with automatic mattress lifting system is a bed with a frame and an internal drive system for raising a mattress above the frame, allowing the user to easily change the sheets or other bed coverings. The mattress rests on a mattress supporting platform, which, in the lowered position, is received within the frame. In operation, driven motion of an internal rod caused by a drive system located within the frame generates rotation in a lever arm. The lever arm is secured to a shaft that extends across the frame, and rotation of the shaft causes a pair of supports to rotate. Upper ends of the supports are joined to a lower surface of the mattress supporting platform, thus driving upward movement of the mattress supporting platform. The sheets cover both the mattress and the platform, allowing the sheets to be changed without having to manually lift the mattress.
