FIELD: furniture.
SUBSTANCE: device for transformation of upholstered furniture consists of two transforming mechanisms which are mirror, of the synchroniser of work of transforming mechanisms, clamps of transforming mechanisms in the combined and spread out positions, and also loading jacks. Each transforming mechanism includes the fixing lath attached to basic elements of design of the transformed product, and two links supplied placed in tops of triangles in junctions of pivotal connection with the fixing lath, with the basis of the first section of a berth and the basis of the second section of a berth. Straight line between axes of junctions of pivotal connections of both links with the bases of the first section of a berth of a transformed product and according to a fixing lath, a straight line between axes of junctions of pivotal connections of the first link with the basis of the first section and a fixing lath, and a straight line between axes of junctions of pivotal connections of the second link with the basis of the first section and a fixing lath, make one parallelogram. Straight lines between axes of joints of pivotal connections of both links with the bases of the second section of a berth of a transformed product and according to a fixing lath, a straight line between axes of joints of pivotal connections of the first link with the basis of the second section and a fixing lath, and a straight line between axes of joints of pivotal connections of the second link with the basis of the second section and a fixing lath, make another parallelogram. Links are executed with bend, its section perpendicularly direct between joints of a pivotal connection of a link with the fixing lath and with the basis of the first section. The bend size is equal and larger than thickness of the lever of the articulation linkage.
EFFECT: increase of ergonomics of furniture for sitting and lying and on laying-out process simplification.
