Abstract
An elongated, lightweight, insulative, multi-section, break-resistant telescoping tool especially adapted for work around energized electrical lines is disclosed which overcomes breakage problems heretofore encountered in tools of this type by provision of closely fitting, reciprocable, telescoping sections having imperforate bases which preclude air flow centrally through the sections to thereby prevent the quick escape of air from adjacent, surrounding sections during nesting retraction of the tool which serves to cushion such retractive movement and prevent inadvertant breakage of the sections. Spring-loaded buttons are provided for releasably securing the sections in an extended position and are formed of high-impact, shear-resistant deformable synthetic resin material so that the buttons can safely absorb shocks resulting from an accidental dropping of the tool without breakage of the tool sections or the buttons themselves. The tool sections advantageously include an outer tube formed of flexibilized epoxy resin and an inner fiberglass reinforced sleeve received within the tube and bonded thereto by means of a polyurethane foam which absorbs a portion of the transverse loads imposed iupon the sections by the buttons during an accidental dropping of the tool.
