FRAMEWORK COMPRISING SEPARABLY CONNECTED PROFILE BARS

摘要

The framework of separably connected profile bars, some of the bars have longitudinal slots and others have hollow sections for engagement of a coupling member in their face ends. The coupling member consists of a bearing housing with an upwardly oriented wedge surface and a holding member with a matching inclined surface which is forced against the wedge surface by a spring force. The holding member can be moved in a longitudinal direction by an eccentric pin arranged transversely to the profile bar and located with its actuating end on a cross hole of the profile bar so that a coupling hook at the end of the holding member is movable both longitudially relative to stationary projections of the bearing housing as well as laterally due to the rising movement of the matching inclined surface along the wedge surface.
