A hinge joint assembly for flexibly connecting rigid structural components in the construction of modular buildings. More specifically, the joint permits the fastening of struts (rods, tubes, or the like) and/or panel studs with three possible degrees of rotational freedom for each strut or stud connected. Each joint assembly includes a plurality of interacting fastening units having a connecting member to which a longitudinally extending strut or stud is rotatably connected about its longitudinal axis, the connecting member in turn being rotatable about either of two axes which are perpendicular to each other and to the longitudinal axis of the strut or stud. Several forms of joint assembly are shown and described.

DETAILED DESCRIPTION The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1.
A hinge joint assembly composed of non-resilient material for flexibly connecting a plurality of at least three structural building components in the construction of modular buildings, said hinge joint assembly comprising: (A) at least one hinge pin, and (B) a plurality of similar flexibly interacting fastening units mounted for rotation about said hinge pin and each including: (1) at least three rotatable connecting members each having means for loosely and rotatably engaging a longitudinally extending rigid structural component for rotation about the longitudinal axis of the component, said longitudinal axis extending perpendicular to the axis of rotation of the connecting member, and (2) a corresponding number of intermediate means mounted on said hinge pin and engaging said connecting member for securing said connecting member to said hinge pin, said connecting member being in fixed engagement with said intermediate means for pivotal movement of said connecting member about said hinge pin, and in rotatable engagement with said intermediate means for rotational movement relative thereto about an axis perpendicular to the axes of said pin and structural component and skew relative to the axis of the pin.
2.
A hinge joint assembly according to claim 1 further characterized in that: (A) said joint assembly includes a plurality of hinge pins, (B) at least one of said hinge pins is an elongated cylindrical structural component engaged by the joint assembly, and (C) additional fastening units are mounted for rotation about the longitudinal axis of said structural component.
3.
A hinge joint assembly according to claim 1 further characterized in that said means for rotatably engaging a structural component comprises a cylindrical socket coaxial with said component and adapted to receive an end of said component.
4.
A hinge joint assembly according to claim 3 further characterized in that said socket is internally threaded
