Abstract: A top plate (12) with a padded cushion (18) is pivotably mounted on a bottom plate (16) . The padded cushion (18) is fixed in position on the top plate (12) by an integral rigid retaining ring ( 20) , with inner beading (34) of the retaining ring (20) extending in a clamping fashion beneath outer beading (26) of the top plate (12). An annular groove (22) close to the outer edge of the top plate (12) means that the remaining annular wall (24) with the marginal beading (26) is only connected to the top plate (12) via a thin bridge, said bridge constituting an articulation zone (28), so that, when the retaining ring (20) is lifted off, the annular wall (24) functions as a flexible tongue and can be moved elastically inwards.

Abstract: Each end of a lifting hose (10) is sealed pressure-tight by means of two clamping strips (12, 14) , one strip (12) having a row of projecting pegs (20) , and the other strip (14) having holes (30) in a corresponding arrangement. The pegs (20) have thickened heads (24), and the holes (30) are stepped, thus giving rise to annular supporting surfaces into which the heads (24) latch in the clamped position of the two flatly folded layers (40, 42) of the hose (10).

Abstract: A U-shaped outer frame (18) and a rectangular inner frame (14) form the guide framework for the lift platform (24) of a lifting apparatus. The two frames (14, 18) are each made integrally of glass-fibre-reinforced plastic and have sliding articulations (20), which are moulded on integrally and are guided by runners. The sliding articulations (20) are formed on hook-like extensions (38) of the longitudinal shanks (28, 32) of the frames (14, 18), and when the lift platform (24) is in its lowered position, the sliding articulations (20) are substantially below the outlines of the outer frame (18) and above the outlines of the inner frame (14).

Abstract: Pivot-mounted on a bottom plate (12) is a top plate (14) which supports an upholstery pad (16), the latter being secured by a retaining ring (18) around the circumference of said top plate (14). The top plate (14) has an outer rim with a polygonal contour so that the retaining ring (18) only engages under said top plate (14) at the polygon corners. This gives rise to a number of clamping zones arranged at intervals around the circumference, between which there are permanent cavities. The retaining ring (18) can thus be easily removed, by local deformation, from the top plate (14) to enable the rotatable seat (10) to be cleaned.

Abstract: In an elongate housing (12), a valve body (30) comprising two annular chambers (36) is mounted so that it can be displaced longitudinally, one each of which communicates with a connection neck of the housing (12) via a radial hole (28). In the neutral position, a further central radial hole (28), which communicates with a water inlet, is sealed against the annular chambers (36) by O-rings (38). A pivotable rocker (44) with a broad surface has two operating extensions (50) which contact the front end of the valve body (30). By swivelling the rocker (44), the central radial hole (28) can be selectively connected to communicate with each of the two outer radial holes (28).

Abstract: Situated on the underside of a lifting plate 24 of a bathtub lift is a value housing 40 containing an inlet valve 48 and an outlet valve 50. Both valves 48, 50 are actuated as required by a joint rocker 76 which in turn in the event of non-actuation is held by the plungers of the two valves in its neutral position. Pressure applied to one end of the rocker 76 opens the inlet valve so that the lifting plate 24 of the bathtub lift is raised. When the rocker is released 76, the inlet valve 48 closes and when the other end of the rocker 76 is pressed the outlet valve opens causing water to be discharged from the lifting hose of the bathtub lift via an outlet opening 68 in the valve housing 42.

Abstract: The lift platform (16) of a lifting apparatus (10) can be raised and lowered by a hydraulically operated lifting device (12) . The back rest (18) can be swivelled backwards and forwards by a swivelling device (19). A multi-valve housing (20) is connected via pressure lines (24, 26) to the lifting and swivelling devices (12, 19). A hydraulic water supply line (22) feeds hydraulic water to the multi-valve housing (20) . The multi-valve housing (20) contains main valves for filling or emptying the lifting and swivelling devices (12, 19). The multi-valve housing (20) is triggered by an external manual control unit (30) via a flexible multiple line (28) .

Abstract: The lift platform (16) of a lifting apparatus (10) can be raised and lowered by means of an hydraulically operated lifting device (12). The back rest (18) can be swivelled backwards and forwards by a swivelling means (19), which is likewise hydraulically operated. Both working devices (12, 19) are connected to a multi-valve housing (20), which is located beneath the lift platform (16) and which has no manual control means at all. The valves are triggered hydraulically by remote control. For this purpose, a manual control unit (30) with a number of built-in servo valves is connected to the multi-valve housing (20) via a flexible cable (28), which contains a number of thin control hoses and an hydraulic water supply hose.

Abstract: A rotary plate (14) is mounted on an oblong bottom plate (12) in a manner which permits the former's longitudinal displacement.The bottom plate (12) features a number of transverse grooves (46) extending over its full width, between which grooves (46) are formed articulating webs (48) at the bottom and top face of the bottom plate (12) around which articulating webs (48) adjacent strips of the bottom plate (12) can be folded relative to each another. The bottom plate (12) forms in the area of the articulating webs (48) a multi-member belt or band with a sprung flat-shape recovery action. The rotary plate (14) features a central pin (36) which can be moved from a locked position into an unlocked position and vice versa. In the locked position, the pin (36) engages in a hole (30) of the bottom plate (12) to prevent the rotary plate (14) from further displacement.

Abstract: A rotary plate (14) is longitudinally displaceable on a base plate (12) of extended length. The rotary plate (14) features a central pin (36) which can be moved from a locked position into an unlocked position and back. In its locked position, the pin (36) engages with a hole (30) in the base plate (12) and prevents a displacement of the rotary plate (14).

Abstract: A back rest (10) capable of being mounted on a lift platform of a lifting apparatus has a foot part (12) and, thereon, a slab (14) pivotable about a swivel axle (34), the slab (14) forming the back part. At the rear, there is a transverse supporting wall (44) moulded or attached to the slab (14) and spaced sufficiently apart from the swivel axle (34). Between the supporting wall (44) and the bottom (24) of the foot part (12), there is a transverse piece of hose (16) disposed parallel to the swivel axle (34) and closed at its ends, which is connected to the hydraulic-water system of the lifting apparatus via a manual control valve. When the piece of hose (16) is filled, the slab (14) is raised to an upright position even if the upper part of the user's body is applying a load to the slab (14).
