Frame e.g. door frame, for e.g. door wing, in wall opening, has screwing unit with upper extension supported in stepped boring in boring section with smaller diameter, where boring penetrates frame profiles from reveal side to rebate side

摘要

The frame has an assembly fixture (1) comprising two screwing units (I, II) boltable with one another along a screwing axis (4). The screwing unit (II) divides into an upper extension (11) and a lower extension (12), where the extensions run toward the screwing axis. The screwing unit (II) with the upper extension is supported in a stepped boring in a boring section with a smaller diameter. The stepped boring penetrates frame profiles from a reveal side to a rebate side of the frame profiles. The screwing units (I, II) are implemented as a threaded sleeve (2) and a grubscrew (3), respectively.
