Abstract
A therapeutic bed for treating medical complications of immobility oscillates in a circular rhythmic fashion, an upper frame being caused to pivot about its central longitudinal axis with respect to an intermediate frame which is caused to pivot about its central lateral axis with respect to a base frame. Independent mechanical means having variable speed controls each employ a rotating eccentric arm which oscillates the respective pivoting frame. Shock absorbers provide smooth motion.
Claims6
A therapeutic bed, comprising:
- a rectangular base frame adapted to rest on a floor;
- a rectangular intermediate frame substantially centered above said base frame, said intermediate frame journaled thereto for pivoting about its lateral axis;
- a rectangular upper frame adapted to support a mattress substantially centered above said intermediate frame, said upper frame journaled thereto for pivoting about its longitudinal axis;
- means for selectively controlling the angle of said intermediate frame with respect to said base frame;
- and
- means for oscillating the pivoting of said intermediate frame with respect to said base frame, which includes:
- first power means, which is mounted on said intermediate frame and turns a shaft having a link pivotally and eccentrically attached thereto and is pivotally attached at its other end to said base frame;
- and
- means for oscillating the pivoting of said upper frame with respect to said intermediate frame, which includes:
- second power means, which is mounted on said intermediate frame and turns a shaft having a link pivotally and eccentrically attached thereto and is pivotally attached at its other end to said upper frame.
