Abstract: A mechanism for removably joining elongate frame members comprised essentially of a series of geometrical apertures in some frame members which are adapted to receive specially designed, geometry-conforming detents or keys which have been affixed to, or constructed integrally with, adjoinable frame members. Major connecting action is effected by insertion of one member, a strut which has special cylindrical projections at its ends, into another member, a spar which has a special keyway for receiving said projections, and rotating said strut into a position which, because of the unique geometry of said projections and internal surfaces of said spar, result in capture of the projections, thus immobilizing said strut.Two adjunct locking mechanisms are suggested for rigidifying connections of the preferred embodiment. The first such locking mechanism employs detent means, the second, lever and snubbing action.
