<p>This invention relates to a multi-position bed such as is used in hospitals for persons who by reason of physical disability or age are unable to turn or move themselves in bed. As shown in Figure 4 the bed comprises a base frame (1) supported on casters and having a pair of pivoted angled lifting arms (2). One of the pair of lifting arms is pivoted in turn to an interlink pivoted to a pivot bracket (4). The other lifting arm (2) is pivoted directly to a second pivot. …<??>The pivot brackets (4) and (5) act as the pivot supports for the centre section (6) of a mattress platform which also comprises two side sections (7). The side sections (7) are not hinged directly to the centre section but simply have interengaging features in the form of side frame registers (11). When the bed is used as a turning bed the interengaging features (11) disengage. …<??>The side sections (7) are carried by pairs of links (8) and (9) which join the pivot brackets (4) to the side sections (7) at points underneath the side sections. These side sections are also connected by side frame pivot arms (13) to an end pivot frame (12), at each end of the bed, the pivot frame (12) being rigidly connected to the centre bed section (6). The movement of the bottom links (8) is restricted, in a downward direction, by bottom link stops (10). …<??>The links (8, 9) may be disconnected and the side sections (7) connected rigidly to the centre section (6) so that the mattress platform can be caused to tilt bodily in a lateral sense.</p> |
