Abstract
A demountable structure, for example for forming scaffolding, shelf assemblies or frame assemblies comprises a pair of co-axial spaced connection and support members with a connection element or bracket interposed between the ends of the members. The engaging surfaces of the support members and brackets form frustum cone surfaces and are drawn together and stiffened by a threaded stem passing therethrough.
Claims4
A support structure comprising:
- a first upright tubular member;
- a partition disposed across one end of the first tubular member having an outwardly facing depression formed therein, the side walls of which define a frustum cone surface;
- a bracket having an opening extending axially therethrough and having first and second opposed ends each of which defines a frustum cone surface, said first end engaging said depression, the bracket including first and second separately formed interlocking sections each of which incorporates an outwardly extending flange, the flanges defining opposed horizontal surfaces;
- a second upright tubular member axially aligned with the first tubular member;
- a partition disposed across the end of the second tubular member having an outwardly facing depression formed therein the side walls of which define a frustum cone surface that engages the second end of the bracket;
- a stem passing through the opening of the bracket and engaging the partitions of the first and second tubular members;
- and
- a horizontal shelf engaged between the horizontal surfaces of the bracket flanges.
