Abstract
A multi-section telescoping pole for manipulating a tool. Sections of the pole have apertures. A pinch safety locking assembly includes a button configured for movement by a digit on a user's hand to a first position by a first resilient member when received in aligned first and second apertures to restrain the second section from moving relative to the first section and to a second position against a resistance provided by the first resilient member and against an elastic stop to permit relative longitudinal movement between the first and second sections. The pinch safety locking assembly is additionally configured to facilitate assembly by movement of the button by use of an excessive force to a third position against a combined resistance of the first resilient member and the elastic stop to permit relative movement between the pinch safety locking assembly and the second section.
