Abstract

New structure for collapsible folding beds, of the type that include u-frames, ends for headrest and feet, articulated on central beams, two on each side, with the possibility of regulating the relative inclinations of those extreme frames, in connection with the frames of the feet, which are characterized by the two stringers on each side are linked together by some, pieces in the form of a bridge, with two parallel plates, and whose bridge offers a notch, with three axes subtendidos between both plates, the, that articulate, the stringer, next to the head in the part recayente to the entalla of the bridge, what allows his tilting in inclined form with support in a inferior projection obtained in the same plate, a second central axis in which articulates another small frame similar to those of the feet of the piece of furniture, but of smaller height, and whose tilting is limited by the brief route of a projection that it offers laterally in s or end that is inserted in a curved and curved window made in the inner plate, and whose end of the frame acts as support of the end of the beam close to the head when it is in horizontal position, this small central frame being subjected to the action of a strong spring anchored below the pivot axis and with another end attached to the stringer next to the support frame of the feet of the user, this last stringer being articulated on the third axis subtended between the parallel plates, below the bridge, which acts as a stop to prevent the bed from leaving its center.
