Abstract
A handle assembly (10) for a floor maintenance machine (12) includes a hollow handle pole (26), a handle (84) formed of a foamed polymer, and a device (36) for adjustably locking the handle pole (26) relative to the housing (14) of the floor maintenance machine (12). The locking device (36) includes a foot-operated lever (44) of a stamped, generally U-shape. The handle (84) is formed of a top section (90) and a bottom section (92), with hand grips (156) being integrally formed solely with the top section (90). Pivotable triggers (120) are pivotally mounted to cylindrical pivot bosses (118) formed in the handle (84), with unintentional pivoting of the triggers (120) being prevented by a slideably mounted, lock-out device (164). Trapezoid-shaped extensions (106) are formed on the bottom section (92) and include edges (108) for abutting with the floor when the handle assembly (10) is tipped to reduce the risk of the handle (84) cracking at the upper end of the handle pole (26).
