Abstract
A connection assembly includes at least two components each formed with a body extending along a respective axis and a respective plurality of angularly equispaced alternating tongues projecting radially from the body and grooves for meshing with the tongues and grooves of the other component upon relative angular displacement of the components, so that the components are not able to be separated in a direction transverse to the axis upon the relative angular displacement.

A connection assembly comprising:
- a first elongated rigid profiled component extending along a longitudinal axis and formed with a multiplicity of angularly equispaced notches and a multiplicity of angularly equispaced tongues projecting radially from said first elongated rigid profiled component, said tongues and notches alternating with one another, each of said tongues having an arcuate convex ellipsoidal outer peripheral surface, a pair of undercut surfaces extending inwardly from ends of said arcuate convex outer peripheral surface, and a stem;
- and
- at least one second elongated rigid profiled component formed with a respective multiplicity of angularly equispaced notches and a respective multiplicity of angularly equispaced tongues projecting radially from said second elongated rigid profiled component and alternating with the respective notches, each of said tongues of the second elongated rigid profiled component being of a mushroom-shaped cross section having an arcuate convex ellipsoidal outer peripheral surface and having a pair of undercut surfaces extending inwardly from ends of said arcuate convex outer peripheral surface, and a stem,
- said first and second elongated rigid profiled components being in an engaged position upon mutual axial displacement of said elongated rigid profiled components, so that one of said tongues of the second elongated rigid profiled component slides along a respective one of said multiplicity of notches of the first elongated rigid profiled component, each of said notches of said first and second elongated rigid profiled components being larger than each of said notches, so that said first and second elongated rigid profiled components are mutually angularly pivotal with respect to each other in said engaged position, the undercut surfaces of one respective tongue of the first elongated rigid profiled component engaging the undercut surfaces of a respective pair of tongues of the second elongated rigid profiled component flanking said one respective tongue and thereby preventing separation of said elongated rigid profiled components in a direction transversely to the longitudinal axis in the engaged position during pivoting.
