Foldable lightweight stretcher

摘要

A foldable stretcher for transporting an object. The stretcher comprising: a plurality of substantially plane members pivotally connected with each other in series by means of hinges there between; handles pivotally connected to outermost of the plane members; and, at least two pluralities of props. The stretcher further comprises at least two pairs of sufficiently stiff wires. Each pair of the wires arranged along a corresponding long side of the stretcher; each the wire is mechanically connected to the stretcher at least two connection points; the handles adapted for actuating a tautening of at least one of the wires of each pair of wires by fixation of the handles when the stretcher is in the unfolded position.

1. A foldable stretcher for transporting an object; said stretcher comprising
a. a plurality of substantially plane members pivotally connected with each other in series by means of hinges therebetween; said plurality of plane members reversibly configurable into an unfolded operative position and a folded transport position; b. handles pivotally connected to outermost of said plane members; c. at least two pluralities of props; said props adapted to support said plane members placed on a horizontal surface in said unfolded position; said props are perpendicular to said plane members placed on a horizontal surface in said unfolded position; said each plurality of props is uniformly spaced along a corresponding long side of said stretcher; said each plurality of props pivotally connected to said hinges in an individual manner; wherein said stretcher further comprises at least two pairs of sufficiently stiff wires; each pair of said wires arranged along a corresponding long side of said stretcher; each said wire is mechanically connected to said stretcher at at least two connection points; said handles adapted for actuating a tautening of at least one of said wires of each pair of wires by fixation of said handles when said stretcher is in said unfolded position; further wherein said tautening of said wires triangularly fixates said hinged props in a supporting position and a first wire and a second wire of said each pair of wires fixates even and odd props, respectively; further wherein said plane members are characterized by a descending width.
