Claims
- 1. A device for positioning a patient on a bed having opposed sides by pulling a sheet positioned under the patient toward one side of the bed comprising:
- a) a support frame including a base and a pair of spaced support arms extending upwardly from said base;
- b) a horizontal roller supported by said support frame, said roller including a central shaft, an outer surface, and attachment clips on said outer surface;
- c) an electric motor mounted on said frame and operatively attached to said central shaft;
- d) first and second wheeled legs, each leg having opposed ends, said legs being pivotally attached adjacent one of said ends to said frame base, and including releasable locking means for releasibly holding said legs perpendicular to the axis of said roller, and return means for urging said legs toward positions perpendicular to said roller, said legs being pivotal in either direction toward an orientation parallel to said roller; and
- e) electrical circuitry controlling the operation of said motor, and thereby the rotation of said roller.
- 2. The device of claim 1, further including a sheet guide bar parallel to and beneath said roller, said guide bar extending from one support arm to the other support arm.
- 3. The device of claim 1, wherein said electric motor includes a motor shaft operatively connected to said central shaft through one of said support arms.
- 4. The device of claim 1, wherein said electrical circuitry includes an on/off switch, a position switch to control the direction of rotation of said roller, an operating switch to actuate said motor, and a connecting cable attaching said operating switch to said electrical circuitry, said operating switch being capable of actuating said motor only when said on/off switch is in the on position.
- 5. The device of claim 1, further including a timer.
- 6. The device of claim 1, wherein all of said electric circuitry, except for said operating switch and connecting cable is enclosed.
- 7. A device for positioning a patient on a bed having opposed sides by pulling a sheet positioned under the patient toward one side of the bed comprising:
- a) a support frame including first and second vertical roller support arms, said support arms having upper ends and lower ends, and a horizontal connecting arm joining the lower ends of said support arms;
- b) a horizontal roller supported by said support frame, said roller including sheet attachment means and a central shaft with opposed ends;
- c) an electric motor mounted on said connecting arm and operatively attached to said roller through the interior of one of said support arms;
- d) first and second wheeled legs having inner ends pivotally attached beneath said frame, and including releasable locking means for releasibly holding said legs perpendicular to the axis of said roller, and return means for urging said legs toward positions perpendicular to said roller said legs being pivotal in either direction toward an orientation parallel to said roller; and
- e) electrical circuitry controlling the operation of said motor, and thereby the rotation of said roller, said circuitry including a timer for stopping operation of said motor after a predetermined time period.
- 8. The device of claim 7, further including a horizontal, vertically adjustable sheet guide bar extending from one support arm to the other support arm beneath said roller.
- 9. The device of claim 7, wherein the upper ends of said support arms are slotted to receive the ends of said roller shaft.
- 10. The device of claim 7, wherein said support arm include inner faces, said device further including shields adjacent said inner faces covering the intersections of said roller and said support arms.
- 11. The device of claim 7 wherein said electrical circuitry includes a controller, and wiring joining said controller to said motor, said wiring extending through the interior of said frame.
