Abstract

Lifting head mechanism for bed frames, characterized in that the basic rectangular frame, supported by four legs, provides, on a crossbar that relates to the two headboard, a cylindrical axis parallel to the said crossbar on which it is supported by two short vertical plates finished in bush-guides of the shaft, which rests at its ends in sleeves provided on the internal faces of said legs, extending the shaft itself through one of these sleeves to penetrate, through a terminal in square, in the internal gap of the respective leg, square which can be actuated from the outside by means of a suitable bore, it being provided that said shaft is of inverse rotation and has, in the sections between the central supports and their respective ends, threads of opposite orientation, on those that are coupled and run other sockets with a flat upper and drilled tab that articulate respec the two connecting rods, which, after crossing each other in parallel planes, are articulated in turn and at their opposite end with a forked bridge piece, which is also through pins to a head frame, whose frame adopts the shape in accordance with the inside perimeter of the general frame and has a length approximately equal to a quarter of that of the former, the ends of the two branches of the "U" that make up this frame have a flattened arrangement to determine the two lugs that, by means of through shafts, locate the movable headboard inside said basic frame, two pop-up stops having been established under the corresponding top of the bed base to support the head frame in its most depressed position.
