Abstract

An adjustable articulated bed including a bed foundation having a body member and a generally separate head member, a mattress supported on the foundation, an electrical motor coupled to the head member, and a support frame which supports the mattress, foundation and motor. The motor when operated pivots the head edge of the head member upwardly, moves the head member away from the body member along a roller-glide assembly, and together with the pivoting motion moves the entire foundation towards the head edge of the frame. Thereby, the head portion of the mattress does not slide with respect to the foundation head member and the head edges of the mattress and foundation travel up in a vertically straight line thereby remaining in constant close proximity to the wall at the head edge of the bed. Advantageously, the person lying on the bed experiences a similar movement; that is, his shoulders move in a straight vertical line. Thus, his head does not move horizontally out of position relative to lamps, radios, telephones or other nearby objects as the head portion of the mattress is moved between its flat and raised positions. Also, his buttocks are not pinched by the crease in the mattress as it folds up. The foundation body member has articulated foot, thigh and seat portions which are adjustable by another electrical motor to configure the upper surface of the body portion of the mattress as desired.
