Abstract
A power head for a powered concrete roller screed includes a handle and a driver housing at a distal end of the handle. A cordless, battery-operated driver is received in the driver housing. A head actuator includes a translatable link extending along the handle and an eccentric cam. The eccentric cam is operatively connected to the translatable link within the drive housing such that translation of the translation link imparts rotation of the eccentric cam about a rotational axis of the eccentric cam to an actuated position. The eccentric cam is adjacent a trigger of a cordless, battery-operated driver and is configured to depress the trigger when the eccentric cam is rotated about its rotational axis to the actuated position.
Claims20
A power head for a powered concrete roller screed comprising:
- a handle;
- a driver housing at a distal end of the handle;
- a cordless, battery-operated driver received in the driver housing, the cordless, battery-operated driver including a longitudinal axis, a trigger configured to be depressible in a direction generally transverse to the longitudinal axis, and an output shaft having a rotational axis extending generally perpendicular from the longitudinal axis;
- and
- a head actuator including a translatable link extending along the handle, and an eccentric cam operatively connected to the translatable link within the drive housing such that translation of the translation link imparts rotation of the eccentric cam about a rotational axis of the eccentric cam to an actuated position, wherein the eccentric cam is adjacent the trigger of the cordless, battery-operated driver and configured to depress the trigger when the eccentric cam is rotated about its rotational axis to the actuated position.
