Abstract
The invention relates to apparatus which can be used to move a person supported on the apparatus between a lying position in which the apparatus is substantially flat on a support surface and a seating position supported by the apparatus. The apparatus includes a frame which supports sheet material on which the person is supported. The apparatus can be moved between said conditions with the person supported thereon.
Claims21
Apparatus movable between an erected condition and a substantially flattened collapsed condition substantially adjacent a supporting surface on which the same is mounted, said apparatus comprising:
- a frame having a plurality of members, leg members having pivot points, and an actuating member having a pivot point;
- sheet material suspended between the leg members and the actuating member of the frame and by which a person may be supported, the sheet material being attached at one end to a rotatable member of said frame on which a movement means acts and another end of the sheet material is attached to one of the leg members or actuating member in a fixed position;
- movement means are provided which allow selective movement of the apparatus between said erected and collapsed conditions by acting on the sheet material while said apparatus provides support to the person thereon so as to move the person between a lying position when the apparatus is in the collapsed condition and a substantially seated position when the apparatus is in the erected condition;
- and
- wherein a portion of said sheet material passes around and acts on the actuating member to pivot one end of the actuating member toward the supporting surface and another end of the actuating member is drawn upwardly to initiate movement of the apparatus when the sheet material is wound up by the movement means and commences the movement of the leg members from the flattened collapsed condition to the erected condition.
A lifting means for a person, said lifting means comprising:
- a frame having a plurality of members, leg members having pivot points, and an actuating member having a pivot point;
- a back portion having a top part and a bottom part, said parts being in a relatively angled configuration;
- sheet material suspended between the plurality of members of the frame and being attached at one end to a rotatable member of said frame on which a movement means acts and another end of the sheet material being attached to one of the plurality of members in a fixed position;
- movement means for selectively moving the apparatus between an erected and a flattened collapsed condition by acting on at least one of the plurality of members to move the sheet material which in turn causes the actuating member to pivotally move the leg members apart such that further movement of the sheet material causes pivotal movement of the legs;
- and
- wherein a portion of said sheet material passes around and acts on the actuating member to pivot one end of the actuating member towards the supporting surface on which the lifting means is mounted and another end of the actuating member is drawn upwardly towards a frame member to initiate movement of the apparatus when the sheet material is wound up by the movement means and commences the movement of the leg members from a flattened collapsed condition to the erected condition.
