Abstract: In an anchor for installation into a lightweight construction panel including at least a cover plate, wherein the anchor includes a radial clamping section for firm engagement with the cover plate when installed in a bore formed into the construction panel, the radial clamping section comprises an upper zone provided with axial grooves and a lower zone having transversely extending grooves both in engagement with the walls of the bore in the area of the cover plate.

Abstract: In a combined acceleration and deceleration arrangement with a support and guide structure supporting a carrier element movable between a park position and an end position and an energy store which is charged when the carrier element is in the park position and discharged when it is in the end position, the carrier element has a guide part and a securing part and each has an engagement stop, the energy store being connected to the securing part and an operating element being connected to the guide part.

Abstract: In an arrangement for damping and/or retarding a movable part, including a housing with a pressure member slidably supported in the housing and a cylinder piston unit arranged in the pressure member and in the housing wherein the housing includes a mounting flange with a support surface provided with at least two throughbores, the mounting flange has at least two spaced guide surfaces which are oriented at least approximately normal to the support surface, the guide surfaces delimiting an adapter area at several sides thereof. The damping arrangement can be used and installed rapidly and accurately to various types of hinges.

Abstract: In a damping mechanism for a pivot door arranged in a door frame, comprising a door fixture arranged in or on the door panel, a frame fixture arranged in or on the door frame, a damper arrangement arranged in the door fixture or the frame fixture and a damper arrangement counter part mounted in the frame fixture or in the door fixture, a damper arrangement with a brake catcher provided with a damper member includes a spring element which pulls the brake catcher into the fixture and the damper arrangement counter part includes at least one trigger element which is abutted by the brake catcher during closing of the door, so that the damper arrangement begins to dampen the pivot movement of the door as soon as a fixture part of the door comes into contact with a fixture part of the door frame.

Abstract: In an anchor for the attachment to flat building components including two cover plates and an intermediate support core layer wherein the anchor comprises an expansion body and a wedge body which is inserted into the expansion body and includes an opening for inserting a mounting means, the installed anchor is disposed in an opening of the component which extends through the cover plates and the intermediate support core plate. The expansion body has spreadable engagement elements, wherein, with the anchor installed, a cylinder zone is in contact with the bore wall of the first cover plate, and a wedging zone spreads out engagement elements behind the first cover plate. A part of the anchor is additionally disposed in the second cover plate.

Abstract: In an anchor for use in a construction panel which includes upper and lower cover plates, wherein the anchor includes a cylinder body, a displacement body and a cement container provided with desired rupture locations and installed in the cylinder body and the cylinder body is provided with engagement elements for extending behind the upper cover plate, the cement container includes at least two chambers separated by an intermediate wall and is provided with an upper and a lower opening each closed by a thin-walled rupturable foil, with the intermediate wall being also rupturable by the displacement member upon movement thereof into the cylinder body.
