JOINING ASSEMBLY FOR TWO BAR-TYPE HOLLOW PROFILED MEMBERS

摘要

In a connecting device for connecting a first extruded hollow profile ( 10 ), having a profile channel and at least one undercut groove space on a longitudinal groove ( 20 ), to another such workpiece by way of a screw element or other member which passes through an opening ( 20 ) in the workpiece and can be inserted into the interior ( 22 ) of the other workpiece, there is fixed to the end face ( 14 ) of the hollow profile ( 10 ) a strip-like socket profile ( 34 ) which runs radially with respect to the profile channel ( 12 ) and has at least at one end a stepped face ( 35 ) for receiving the screw element, which screw element in the rest position lies inside the side contours of the socket profile ( 34 ) and in the connecting position projects beyond the socket profile at least on one side and engages in a retaining manner in the undercut space of the other hollow profile ( 10 ). The socket profile ( 34 ) has a baseplate ( 36 ) on a head strip ( 38 ) which is of shorter length in longitudinal section than the length of the baseplate, and part of the latter projects beyond the end face(s) of the head strip ( 38 ) to form an upper or stepped face ( 35 ).
