Abstract
The disclosure relates to an extendible arm for a camera stand or the like, comprising an outer elongate rigid sleeve and an inner elongate rigid sleeve telescopically slidable with respect to the outer sleeve to extend therefrom by a variable amount. One end of the inner sleeve disposed within the outer sleeve has a detent mechanism for locking the inner sleeve in any of a number of positions of extension with respect to the outer sleeve and a release member for the detent mechanism is provided at the other end of the inner sleeve which projects from the outer sleeve with a connection between the release member and detent mechanism extending through the inner sleeve for remote operation of the detent mechanism by the release member.
