Claim:
1. Apparatus, comprising: first and second pole assemblies; each of the first and second pole assemblies comprises: the first pole assembly is mounted rotatably to the second pole assembly with a joint assembly including a first joint component thereof carried by the slide of the first pole assembly mounted rotatably to a second joint component thereof carried by the slide of the second pole assembly; the first joint component is releasable from the second joint component for releasing the slide of the first pole assembly from the slide of the second pole assembly for releasing the first pole assembly from the second pole assembly, when the first pole assembly is rotationally offset relative to the second pole assembly via the joint assembly; the first joint component comprises a pin, the pin includes outwardly-directed lugs and an inwardly-directed notch between each pair of adjacent outwardly-directed lugs; the second joint component comprises a socket, the socket includes inwardly-directed lugs and an outwardly-directed notch between each pair of adjacent inwardly-directed lugs; the pin is rotated to the socket; the outwardly-directed lugs are behind the inwardly directed lugs; the outwardly-directed lugs relate to the outwardly-directed notches and the outwardly-directed lugs relate to the inwardly-directed notches for allowing the first joint component to be pulled apart from the second joint component for separating the first pole assembly from the second pole assembly, in the rotationally offset position of the first pole assembly relative to the second pole assembly; and the inwardly-directed lugs interfere with the outwardly-directed lugs behind the inwardly-directed lugs for preventing the first joint component from being pulled apart from the second joint component for preventing separation of the first pole assembly from the second pole assembly, other than in the rotationally offset position of the first pole assembly relative to the second pole assembly.
