Abstract:
1. A telescoping pole for manipulating a tool from a position a selected distance away from a workpiece, said pole having an extremity with means for connecting the tool thereto and further comprising: a tubular first section having a female end and a predetermined shape, said first section including a first aperture and an interior which defines an axial path and has an interior surface which is uniform about a periphery thereof; a second section having a male end slidingly engaged within said interior of said first section through said female end, said second section having a second aperture and a predetermined shape corresponding to said shape of said first section and being slidable along said axial path; and pinch safety locking means including a button configured for manual movement of said button by a digit on a user's hand within aligned said first and second apertures from a first position radially outside an outer periphery of said first section radially inwardly against a resistance provided by a first resilient member so that a top surface of said button becomes located at a second location just inside an inner surface of said first section whereat an end of said button remote from the top surface engages an elastically compressible stop having a high resistance to yielding to permit relative longitudinal movement between said first and second sections without the digit on the user's hand becoming pinched between said first and second sections, said pinch safety locking means being additionally configured to facilitate initial assembly inside said second section by movement of the top surface of said button by the use of an excessive force to a third position just inside an inner surface of said second section against a combined resistance of said first resilient member and said elastically compressible stop to permit relative movement between said pinch safety locking means and said second section and a sliding of said pinch safety locking means along said axial path to a position where said button is aligned with and received in said second aperture.
