Abstract

A mechanism for transforming furniture from a sitting position to a lying position, consisting of two mechanisms, right and left, of identical construction, being a mirror image of each other, and each of these mechanisms has a lifting subassembly, which includes a front arm with its upper end articulatedly connected to the front angle bracket and a rear arm with its upper end articulatedly connected to the front angle bracket, and from the lower end of the front arm a short front arm extends, which is articulately connected to the rear angle bracket, and the rear arm passes with its lower end into a short rear arm, which is articulately connected to the rear angle bracket, characterized in that each of the mechanisms, right (MP) and left (ML) has a sliding subassembly (1) composed of a fastening strip and a sliding strip (4), wherein the sliding strip (4) in its front part is in the form of a shaped plate (8) with a shaped recess (9) in the shape of an arc,wherein a plate connector is attached to the sliding strip (4) near its rear part in a pivoted manner on a pin, connected via rods to the rear part of the fastening strip, and in the front part the fastening strip is connected via a front rod (13) to a shaped plate (8), while in the shaped recess (9) of the shaped plate (8) of the sliding strip (4) there is a pin (23) mounted in the front rod (13) connecting the fastening strip with the sliding strip (4). A sleeve (20) is mounted in the plate connector, and the lifting subassembly (2) has a guide plate (21) rigidly attached to the rear part of the rear angle bracket.,
