ABSTRACT:
A device for connecting, rotating and locking together a pair of structural half-columns 11 is disclosed. The device is composed of an identical pair of cyclindrical hub assemblies 12,12a connected at their inner faces by a spring loaded hinge 20; each hub assembly having a structural half-column attached to its outer end. Each hub assembly has a spring loading locking ring 14,14a member movably attached adjacent to its inner face and includes a latch 32,32a member for holding the locking ring in a rotated position subject to the force of its spring. Each hub assembly also has a hammer 36,36a member for releasing the latch on the opposing hub assembly when the hub assemblies are rotated together. The spring loaded hinge connecting the hub assemblies rotates the hub assemblies and attached structural half-columns together bringing the inner faces of the opposing hub assemblies into contact with one another. The hammer members 36,36a release the latch members 32,32a on the opposing hub assemblies 12,12a and the locking ring members 14,14a rotate together to join the half-columns and form a single structural column.
