Abstract (en)
[origin: US4847930A] A raising device for attachment to hospital beds consists of an oval tube mounted in a support and which can be rotated and locked in any desired position of rotation, on whose upper free end a handgrip is arranged by which the patient can pull himself up. He can swing himself to the edge of the bed by rotation of the oval tube, and as soon as the oval tube is pre-loaded in an axial direction a clutch engages which is built in to a support arranged on the bed-head. The clutch consists of a clutch member connected as an axial extension of the oval tube which has an axial shoulder formed as a cone which engages in a corresponding conical recess of a radially expandable brake shoe whose outer circumference can be pressed in a free-locking fashion against the inner side of a bearing cup which is a bearing for the clutch. Such a clutch enables the rotational position of the oval tube to be locked in any desired angular position.
