Hinge with reduced bulkiness for vertical movement doors

摘要

A parallelogram hinge for vertical-movement doors comprises a first plate (113) designed to be fastened to the furniture flank, a second plate (117) designed to be fastened to the door and two superposed arms (115, 116) pivotally mounted to the plates to form an articulated parallelogram. A spring (111) for movement balancing is connected to the upper arm (115) at an intermediate position between the arm extremities (119, 120) hinged to the plates and is connected to the first plate (113) at a point (112) below the pivot point (121) of the lower arm (116) on the first plate (113). 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.
