DEFINITION

Classification: 211/195

(under subclass 189) Device wherein the framework is erected to usable form by positioning framework members that were previously loosely connected and tightening the connection(s) between the members after they have been properly positioned, or wherein the framework is collapsed to space saving form by loosening connection(s) between the framework members and moving them together into a smaller space with the members still loosely connected together.
