ABSTRACT:
An extendable utility bar includes a substantially straight elongate outer tube defining an axis and having inner and outer ends and an inner cylindrical surface. A substantially straight elongate inner tube has an axis generally coextensive with the axis of the outer tube and has inner and outer ends and an outer cylindrical surface configured and dimensioned to be slidingly engaged at the inner ends within the outer tube in telescoping relationship to move between fully retracted and extended conditions in which the remote ends of the tubes are minimum and maximum distances, respectively, from each other. A first prying member at the remote end of the outer tube and a second prying member at the remote end of the inner tube are provided. A lock selectively locks the inner and outer tubes relative to each other to fix the positions of the prying members at a distance no less than the minimum distance and no greater than the maximum distance. In this way, the length of the utility bar can be increased to provide increased prying leverage and can be decreased to shorten the length of the bar for storage or mobility.
