Claims9
A hoist for raising an invalid from a seated to a substantially standing position utilizing a single back support sling, comprising:
- a pivotal lifting arm arrangement, said arm arrangement having laterally spaced attachment points for a single back support sling;
- a mobile chassis on which said arm arrangement is mounted, said chassis including a footplate or footrests for the invalid and so positioned that normal pivotal movement of said lifting arm arrangement raises the invalid to the standing position while supported by said simple sling with the feet resting on said footplate or footrests;
- and
- a seat mounted directly on said chassis and onto which the invalid can be lowered, for transport in seated position, by downward pivotal movement of said lifting arm arrangement with the feet of the invalid resting on the footplate or footrests and the upper part of the body of the invalid supported by said back support sling.
A hoist for raising an invalid from a seated to a substantially standing position utilizing a single back support sling, comprising:
- a lifting arm arrangement, said arm arrangement having attachment points for a single back support sling;
- a mobile chassis on which said arm arrangement is mounted, said chassis including a footplate or footrests for the invalid and a side member;
- and
- a seat mounted on said chassis and onto which the invalid can be lowered for transport in the seated position with the feet of the invalid resting on the footplate or footrests and the upper part of the body of the invalid supported by said back support sling, said seat being of elongate shape and pivotally mounted on said side member of the chassis for movement between an operative position for transport of the invalid in the seated position, in which the seat extends from above said side member and laterally of the chassis, and an inoperative position in which the seat generally overlies said side member and does not impede a normal lifting procedure, in said inoperative position of the seat access to the lower part of the body of a raised invalid, with the latter supported by said sling in a substantially standing position on the footplate or footrests, not being impeded.
A hoist for raising an invalid from a seated to a substantially standing position utilizing a single back support sling, comprising:
- a lifting arm arrangement, said arm arrangement having attachment points for a single back support sling;
- a mobile chassis on which said arm arrangement is mounted, said chassis including a footplate or footrests for the invalid and a support socket;
- and
- a seat mounted on said chassis and onto which the invalid can be lowered for transport in the seated position with the feet of the invalid resting on the footplate or footrests and the upper part of the body of the invalid suported by said back support sling;
- said seat having a side support with a lower end spigot pivotally received in said support socket of the chassis so that the seat is pivotally movable between an operative position, for transport of the invalid in said seated position, and an inoperative position in which the seat does not impede a normal lifting procedure and in which access to the lower part of the body of a raised invalid, with the latter supported by said sling in a substantially standing position on the footplate or footrests, is not impeded.
