Standard engineering shapes or profile elements are united by screw clamps to form a releasable and adjustable boom arm or cantilever arrangement. By means of quadrangular clamp bodies, substantially vertical support arms carrying seating or reclining means for a person are mounted on a horizontal support arm and can be individually adjusted in relation thereto. The boom arm is mounted in a further screw clamp provided in the free end of a hydraulic cylinder and piston assembly and is therefore capable of being raised and lowered and swivelled about the lengthwise axis of the cylinder. A hand-grip capable of being pivoted away is provided for the safety of the occupant. Boom arms of this type are employed in bathing installations to safely transport patients and invalids into and out of bath or the like tubs. The releasable and adjustable design concept of the boom arm permits it to be dimensionally adjusted during its initial installation, so that preliminary dimensional surveys are superfluous. In service, the boom arm can be readily adapted to modifications of building or apparatus, changed methods of treatment and varying ergonomic requirements. This provides an increased degree of flexibility and adaptability in application in comparison to welded constructions and therefore greater economy.

A swivelling elevator boom and body support assembly, particularly for bathtub seating devices and the like, comprising: rotatable elevator means having a free upper end; a cantilever support arm having a longitudinal axis extending substantially horizontally, a mounting end and a free end; means for securing said mounting end to said free upper end of said elevator means; at least one substantially vertical support arm for carrying a body support means for accommodating a seated or reclining occupant; clamping means releasably and adjustably connecting said at least one substantially vertical support arm to said cantilever support arm; said clamping means comprising at least one substantially quadrangular block; said at least one quadrangular block further comprising: two clamping jaw portions having mutually opposing inner faces disposed substantially parallel to a first pair of mutually opposing outer faces of the quadrangular block; each clamping jaw portion having at least one free end; a gap defined by said mutually opposing inner faces; a clamping bore formed at said inner faces and having an axis lying substantially in a central plane of said gap and extending substantially perpendicular to a second pair of mutually opposing outer faces of the quadrangular block and receiving therein said cantilever support arm; screw clamping means restraining said free end of each of the two clamping jaw portions; at least said one quadrangular block further comprising; at least one retaining bore oriented in a predetermined position relative to said gap and receiving therein said at least one vertical support arm; and a handgrip and safety bar member mounted in said free end of the cantilever support arm to perform a pivoting motion about said longitudinal axis away from the body support means and provided with groove means for limiting said pivoting motion.
