Connecting concept for basic door structure involves connecting window frame and door box by several screws screwed into press-seam nuts in two directions

摘要

The connecting concept is for the production of a basic door structure (1) including a window frame (2) and a door box (3). These are connected by several screws (6a, 6b, 6c, 6d, 6e, 6f) engaging in press-seam nuts (13c, 13f). The individual screws are either parallel or perpendicular to the plane of the basic door structure.
