Apparatus for turning a person confined to bed
First Claim
1. Apparatus for turning a person confined to bed, comprisinga substantially U-shaped support means surrounding the bed in the middle and from below, said support means including vertically disposed posts extending up to mattress level;
- a pair of rollers disposed along, and parallel to, each long side of said bed, each roller being supported, by a pair of said posts, for rotation about its axis of rotation;
each end of said rollers concentrically carrying bolt means, and each of said posts carrying bearing means for rotatably supporting said bolt means;
means for rotatably driving one of said rollers;
means, carried by at least one of said posts, for moving said bolt means and said driving means relative to one another between a first position wherein said bolt means and said driving means are engaged and a second position werein said bolt means and said driving means are disengaged, said moving means comprising pin means carried by said driving means and recess means carried by said bolt means, said pin means and said recess means extending normal to the axis of rotation of said bolt means; and
a draw sheet connected to, and spanning the distance between, said rollers, said draw sheet extending across the upper side of said bed.

Abstract
An adjustable frame 6 to 20 applied to a bed, supports selectively rotatable rolls 21, 22 at the level of the bed mattress 2 in parallel and close relation thereto. Said rolls are connected to an electric motor 66 via driving chains 40 around the underside of the bed. A draw sheet 28 extends between the rolls across the upper side of the bed and is wound on both rolls with the patient on the draw sheet. A control box 72 operating on low voltage (e.g. 24 V) current enables the patient or a nurse to turn on the electric motor to rotate in one direction or the other. Each roller is provided with an automatic driving and free wheel clutch 34 providing for driving of each roll only in one direction, namely the direction of reeling, so that when the one roll is being driven the other is freely rotating and vice versa. Furthermore, each driving and free wheel clutch unit 34 can be manually connected and disconnected by use of an external eccentric 48.
