Abstract
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.
Claims19
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.
