Abstract

A stretcher, which comprises:

a support frame for supporting a patient;a pair of front legs rotatably coupled to the support frame around a first rotation axis, wherein each front leg supports a front wheel holder frame hinged to the respective front leg around a first oscillation axis parallel to the first rotation axis and supporting a front wheel resting on a rest plane, wherein the front wheel pivots around a respective first pivot axis orthogonal to the first oscillation axis;a pair of rear legs rotatably coupled to the support frame around a second rotation axis, wherein each rear leg supports a rear wheel holder frame hinged to the respective rear leg around a second oscillation axis parallel to the second rotation axis and supporting a rear wheel resting on a rest plane, wherein the front wheel pivots around a respective second pivot axis orthogonal to the second oscillation axis;a handling arrangement for the front wheel holder frame and the rear wheel holder frame;a control module configured to keep the first pivot axis and the second pivot axis always orthogonal to the rest plane on which the front and rear wheels roll.
