Abstract
A parallelogram hinge for vertical-movement doors includes a first plate designed to be fastened to the furniture flank, a second plate designed to be fastened to the door and two superposed arms pivotally mounted to the plates to form an articulated parallelogram. A spring for movement balancing is connected to the upper arm at an intermediate position between the arm extremities hinged to the plates and is connected to the first plate at a point below the pivot point of the lower arm on the first plate. This enables very reduced bulkiness in the direction of the furniture depth, achievement of a great opening angle and better operation of the spring embodied by a gas piston.
