| (57) A lift apparatus for an invalid comprises a guide rail (57a) which is detachably
mounted on a bed (52) on one longitudinal end thereof to extend widthwise along the
bed (52), a movable body (58a, 58b) which is guided to be movable along the guide
rail (57a), and lift means (51) which is mounted on the movable body (58a, 58b). The
lift means (51) includes an upright (59) which is fixed to the movable body (58a)
on a side portion to extend in the vertical direction, and an arm member (65) having
a first end which is coupled to an upper end portion of the upright (59) and a second
end which serves as a working end. The guide rail is mounted on a movable part of
a vertically movable bed (52), and the movable body (58a) is vertically slidably mounted
on the upright (59). According to this structure, the upright of the lift means itself
is not vertically moved but enables cross-directional movement along the guide rail
upon vertical movement of the movable part of the bed comprising a vertically movable
mechanism. |
