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.

Claims

1. 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.

2. The therapeutic bed of claim 1, wherein said upper frame oscillating means further includes means for controlling its speed and for selectively starting and stopping it and said intermediate frame oscillating means further includes means for controlling its speed, whereby the frequency of the rolling action is independently variable as to each axis.

3. The therapeutic bed of claim 1, wherein starting and stopping means and speed control means for said first and second power means are mounted on said intermediate frame.

4. The therapeutic bed of claim 3, wherein said base frame and said upper frame are of open rectangular construction generally equivalent in size and said intermediate frame is rectangular in shape and has dimensions slightly less than those of the openings in said base frame and said upper frame, whereby said intermediate frame along with the power means, starting and stopping means and speed control means mounted on it may fit within said base frame and said upper frame during said longitudinal and lateral pivoting, thereby allowing said upper frame to be at a minimal height.

5. The therapeutic bed of claim 4, further comprising one or more shock absorbers, pivotally connected at either end between said base frame and said upper frame.

6. 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 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 selectively starting and stopping said first power means; 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, whereby said upper frame may be tilted forward or aft about its lateral axis at a desired angle and then oscillated about its longitudinal axis.
