Abstract
A rescue frame to pivot about footings supported adjacent to an upper edge of a vertical incline. The rescue frame comprises a primary tubular member passing through the footings and having attached thereto a number of secondary tubular members so as to form a triangular pyramid having a pulley attached to it's apex such that upon pivoting the frame about the primary member, the pulley will extend out over the edge so that rope and stretcher may clear the incline during a lifting or lowering operation. Upon reaching the top of the incline, frame is pivoted back to laterally transfer the stretcher to another side of the primary member to safety located stretcher above the ground where it may be released from rope.
Claims6
A rescue apparatus comprising:
- a triangular pyramidal-like frame formed by frame bar members that are detachably interconnected, at one end of each said frame bar member to a cross-bar, and at an other end of each said frame bar member said frame bar members are detachably interconnected to a connecting-bar so as to form two A-frames having upper apexes that are connected to said connecting bar;
- ground engagement means rotatably connected to said cross-bar and connected to a ground surface so that said frame is manually rotatable about a longitudinal axis of said cross-bar;
- and
- lifting means attached to said frame such that upon rotation of said frame about the longitudinal axis of said cross-bar, said lifting means is moved laterally, said lifting means comprising a pulley attached to one of said apexes of one of said A-frames and a winch located on said cross bar.
