Abstract

Abstract An obstetrical table has on each side a leg supporting device, each including a foot rest and a thigh support which are adjustable individually and lockable in any desired position relative to a vertical bushing which is rotatably mounted in a bracket fastened to the side of the frame of the table. The foot rest and thigh support connected to the bushing may then be swung about a vertical axis as a unit for further adjustments.

Claim 1
Independent Claim 318 words
In an obstetrical table having a back portion, a seat portion, a leg portion, means for adjusting the back portion to any desired angular position, means for adjusting the leg portion from a position flush with the seat portion to a lowered position from which the leg portion may be inserted at least partially under the seat portion, and a leg-supporting device secured to the table at each side thereof and including a foot rest and a thigh support; the improvement comprising a bracket secured to each side of the table for carrying the leg-supporting devices, the bracket having a vertical bore therethrough, a guide bushing rotatably supported in the bore, means selectively to lock the guide bushing in any desired rotated position within the bore, a horizontal journal carried by the bushing, a head supported for rotation on the journal, means selectively to lock the head in any rotated position on the journal, the head having a bore therein substantially at right angles to the journal, a shaft disposed in the latter bore, means selectively to lock the shaft in any desired position of adjustment in the bore of the head, a foot rest mounted on the end of the shaft for swinging movement about an axis transverse to the shaft, means for selectively locking the foot rest in any adjusted position of rotation about the last-named axis, a vertical shaft carried for rotation by the bushing, means selectively to lock the vertical shaft in any rotated position relative to the bushing, a horizontal sleeve carried by the vertical shaft at its upper end, an arm slidable in the sleeve, means selectively to lock the arm in any slid position in the sleeve, the arm at its end having a holder, a thigh support carried by the holder, and means mounting the thigh support on the holder for swinging movement about an axis transverse to the arm.
