ABSTRACT The invention relates to a furniture hinge, particularly a cup-hinge, which comprises a stationary box-section hinge arm adjustably fastened to a base plate, a swingable hinge cup, a pair of connecting pivot levers which pivotably connect the cup and the arm and a spring assembly located within the box-section hinge arm. Between a control cam of the inner pivot lever and a disc-shaped insert of a pressure spring of the spring assembly there is inserted a transmission pin, which is held and guided by slots that are arranged in the side walls of a housing for the spring assembly and are inclined with respect to the axis of symmetry of the spring. When opening the furniture door, the inner hinge lever and thereby the control cam are swung around a hinge dowel connecting the inner hinge lever and the hinge arm. Thereby, a snapping section of the control cam pushes the transmission pin guided in the inclined slots of the spring housing, which results in the compression of the spring. On opening the door further, the snapping section of the control cam is followed by a sliding section, which is defined by a circle, whose centre coincides with the hinge dowel of the inner hinge lever. Thus, on the further opening of the door wing the pin slides along the sliding section of the control cam, which makes possible a soft and even opening of the door up to the end position when the door is fully open. When closing the furniture door, the hinge lever and thereby the control cam evenly moves in the opposite direction until the sliding pin moving along the sliding section of the control cam reaches the snapping section thereof. The pin inserted in the inclined slots of the housing, aided by the spring force loading it, begins to push away the control cam and thereby also the inner hinge lever. The moment of rotation generated thereby makes it possible to keep the door in its closed position. PAT 15715-1
