  • Publication number: 20240011278
    Abstract: A connector for two components comprises two fittings each with a mounting side, an abutment side opposite the mounting side, and an end face connecting the mounting and abutment sides. At the end faces the fittings may be hooked into one another. The fittings are made of wood or of wood-plastic composite and have one or more generally cylindrical blind holes on their abutment side. The connector comprises, for each blind hole, a molding for removable insertion into the blind hole. The molding has a base surface, a top surface parallel thereto, a substantially generally cylindrical lateral surface connecting these two, and a slanted bore for a mounting screw. The bore penetrates the molding at an acute angle to the base and top surfaces.

  • Publication number: 20230375018
    Abstract: The invention relates to a connector for two workpieces, comprising two fittings which each have a mounting face for a workpiece and an opposite connecting face, on which they can be hooked into one another in a hooking direction extending in parallel with the connecting face. Each fitting comprises, on its connecting face, a shoulder which extends transversely to the hooking direction over its entire width and comprises an undercut, which leaves a ridge on the shoulder. The end face of each fitting remote from the shoulder and adjacent to the connecting face has a lip adjacent to the connecting face and extending over its entire width transversely to the hooking direction. The lip of each fitting engages in the undercut in the respective other fitting in a first position of the fittings in which they are hooked into one another.
