An adjustable handle assembly is provided for use with a hand-held power tool, such as a polisher, to enhance control while operating on delicate surfaces of varying contours. The handle assembly includes a handle mounted to the housing of the tool in a manner that facilitates quick adjustment of the handle between various predetermined positions relative to the housing without the use of tools, turning of nuts and bolts and prolonged work stoppage. The handle assembly also includes lock members on one of the handle and the housing and lock receiving grooves on the other of the handle and housing which can cooperate with the lock members to fix the handle in one of the predetermined positions relative to the housing. For quick adjustment, the handle assembly includes a lock manually movable by a user between a locking position in which the lock members are urged into the grooves to lock the handle relative to the housing and a release position in which the lock members are free to move from the grooves, thereby allowing the handle to be adjusted relative to the housing between the predetermined positions. The handle assembly also includes a cam means located between the lock and the handle to urge the lock members into the locking position with the grooves. The cam means may include cooperating cam surfaces on the lock and the handle.

1. An orbital waxer power tool comprising:a pair of handles and a housing to which the handles are attached with at least one of the handles being movable between various predetermined positions relative to the housing to allow a user to optimize hand positions for a two-handed grip with one hand on each of the handles during operation of the waxer power tool; a motor mounted in the housing; a pad mounted below the housing for rotation in an orbital path upon operation of the motor; lock members associated with one of the movable handle and housing; lock receiving grooves associated with the other of the movable handle and housing which can cooperate with the lock members to fix the movable handle in one of the predetermined positions relative to the housing; an actuator manually movable by a user between a locking position with the lock members urged into the grooves to fix the movable handle relative to the housing and a release position for releasing the lock members from the grooves to allow the movable handle to be adjusted relative to the housing between the predetermined positions; and a cam mechanism between the actuator and the movable handle for urging the lock members into the grooves with the actuator moved to the locking position.
