Movable lattice structure building framework joint - has flattened lug head inside narrow topped nodal piece mounting groove

摘要

A large number of bars converging at varied angles are attachable by hinged joints to each nodal piece, in a system for mobile architectural structures, to enclose areas and/or to provide additional spaces. Each nodal piece (2) comprises a bearing unit with a mounting groove (17,18) or more than one, of reduced cross-section at its opening (28). The hinge joint consists of a pin (23) connectable to a bar (5), with flattened head (22) for insertion in the groove through this narrowed opening, and turned for form-locking in position. The nodal piece can consist of several fixable discs (A,B,C) with complementary cross-sectional groove segments.
