  • Patent number: 4800622
    Abstract: A hinge includes a hinge arm adapted to be snapped onto a mounting plate. The front of the hinge arm is directly or by an intermediate member indirectly engageable into the mounting plate, and the rear of the hinge arm has a tilting lever at which a hook member is formed by which the tilting lever is lockable to the mounting plate. When a door is mounted to the body of an article of furniture, the hinge arm can be engaged into the mounting plate and then fastened thereto simply by applying pressure. Canting of the hinge arm at the mounting plate is prevented.

  • Patent number: 4750238
    Abstract: A hinge has a hinge arm which is snappable onto a mounting plate by means of an intermediate member. The front of the intermediate member is engageable into the mounting plate and the rear of the intermediate member is provided with a pivot lever having a hook member by means of which the pivot lever locks the intermediate member to the mounting plate. A cover member is mounted on the hinge arm and at its rear end has a shoulder which embraces the end of the hinge arm and extends between the hinge arm and the pivot lever, so that the pivot member cannot be released from the mounting plate unintentionally.

  • Patent number: 4691408
    Abstract: A furniture hinge includes a hinge arm having a U-shaped profile and being pushable onto a mounting plate. The hinge arm and the mounting plate have lateral projections and recesses which engage one another. The hinge arm can be locked from movement in the direction of displacement by a resilient steel member which is held at the hinge arm by an eccentric for achieving adjustment of the hinge arm in the direction of the depth of the article of furniture. The steel member is formed as an intermediate element which fully supports the hinge arm.

The marking gauge has an open slot at its rear and a screw in its center. The marking gauge is thus engageable on the mounting plate, and a bore for the hinge casing can be marked at a recess. When reversed, the marking gauge is insertable into a bore for the hinge casing so that the bores for the mounting plate can be marked.
