Patent attributes
A lifting system for leaves of furniture that oscillate about at least one horizontal axis comprises a supporting body which can be connected to a fixed portion of the piece of furniture, a system of articulated levers with a first lever and a second lever which connect the supporting body to a leaf of the piece of furniture, and elastic actuation elements which are functionally connected to the system of articulated levers in order to generate a rotation torque for the system of levers; the lifting system further comprises elements for increasing the rotation torque which cooperate with the elastic actuation elements in order to increase the rotation torque at least along a portion of the oscillation in the direction for opening the leaf that includes the raised position of the leaf.
