Abstract: Convertible multifunctional furniture comprising at least one support base, at least one lifting device which is supported on the support base, a usage unit, a horizontal rotational axis in the longitudinal or transverse direction about which the usage unit can be rotated, and a mounting pin at each end of the rotational axis. At least one scissor mechanism is arranged between the lifting devices and each mounting pin of the rotational axis, at least one scissor limb is connected to a drive of the lifting device at one end and to a support at the other end. The other end of the scissor both is connected to a linear element for controlling purposes, said linear element having a surface which can be coupled to a surface of a wheel that is rotatably coupled to a complementary element of the mounting pin.

Abstract: A method and to a mechanism for adjusting mattresses or chair beds into an operating position comprising extendable guides in which rods run, which merge in a joint pin, which interacts with pins of a mattress, which protrude from a centreline of the mattress. A parallelogram has joints, which are connected to each other through an elongated-hole guide, one joint can be moved in the elongated-hole guide, wherein the rods are articulated to the joint pin, a bushing arranged therebetween, the pin extends into a pulley having a restoring spring, on which pulley a cable is wound and fastened to the joint, at a certain height of the mattress, the cable is tensioned and the angle is reduced, the cable causes the rotation of the pulley in such a way that the mattress is rotated.

Abstract: A bed is described having a mattress or mattress, wherein the mattress has at least two rests arranged on two sides of the mattress parallel to each other, the rests being adapted to be arranged on respective lifting mechanisms intended to bring the mattress into a position such that it can be rotated on itself by 180° about a horizontal axis. According to the invention, the rest support is formed by two extendible elements which converge to form a joint with lower ends attached to the frame at a distance, the floor or the ceiling and at whose top a support is formed for the rests.

Abstract: A system is described for lifting tables, chairs, bed bases, children's high chairs or other items to be lifted; which is lockable and unlockable automatically through at least one universal telescopic snap movement or in a known way comprising at least one pantograph—a vertically moveable load-bearing structure arranged between a base and the bottom of a piece of furniture or element to be lifted and a stopping device intended to keep the pantograph in a desired height position. According to the invention the load-bearing structure is formed by at least one pantograph having a plurality of parallelograms articulated to one another whose lower vertex is articulated to the base and upper vertex is articulated to the bottom of the furniture or object to be lifted and the stopping device is an integral part of telescopic snap movement.
