摘要

Improvements in the lifting mechanism of articulated and flip-up beds for patients, of the type comprising a support frame composed of a middle section fixed to the structure and two articulated and incunable end parts, characterized in that the tilting parts rest on a rigid support articulated to the structure and supported by articulation in rigid elements that are articulated at their lower end in corresponding levers that, hinged at one end to the structure, are suspended by the other end of a cable or chain that is wound on a drum integral to an axis and capable of being actuated by means of a crank and of fixing by means of a braking and holding device so that by means of the actuation of the crank it is possible to vary the inclination of the supporting lever of the supporting means of the corresponding tiltable frame.
