  • Hinge with spring coupling member
    Patent number: 5159740
    Abstract: A hinge includes a hinge arm mounted on a base plate by an intermediate member having a U-shaped cross-section. The hinge arm is retained on the intermediate member by depth and joint adjustment devices, e.g. clamping and adjusting screws. Retaining elements of the intermediate member engage corresponding retaining elements of the base plate at two points staggered over the length of the base plate. The retaining elements are rigid at one such point, and the other point one retaining element is resilient. The hinge arm and the intermediate member engages the base plate with the rigid retaining elements and snaps only the base plate due to the resilient retaining element, in the form of a leaf spring. A rear end the intermediate member is provided with a bridge which defines a gap into which is inserted the leaf spring. A flap is punched from the leaf spring and engages in a recess of the intermediate member arranged underneath the bridge, thus locking the leaf spring to the intermediate member.
