  • Patent number: 6672810
    Abstract: A fitting for connecting two structural components, particularly plates, includes a clamping device mounted in the first structural component and an expanding sleeve which can be secured to the second structural component. A bolt is arranged in the expanding sleeve so as to be longitudinally movable by the clamping device for expanding the expanding sleeve using a conical portion of the bolt. The conical portion of the bolt is an approximately cone-shaped projection whose longitudinal axis is laterally offset relative to the longitudinal axis of the bolt.

  • Patent number: 6146043
    Abstract: A device for connecting two components, particularly furniture plates, includes a cup-shaped assembly element and an actuating element rotatably mounted in the assembly element, wherein the actuating element serves to hold a connecting element in the assembly element, and wherein, in the mounted state of the assembly element, the actuating element can be turned from the outside by a tool. The cup-shaped assembly element has a guide duct which extends obliquely relative to the axis of rotation of the actuation element and is directed toward the actuating element. The guide duct through which the tool is to be introduced for turning the actuating element provides the person carrying out the assembly with the precise position of the screwdriver relative to the actuating element.
