  • Handle for a work apparatus having a drive motor
    Patent number: 9815188
    Abstract: A handle for a work apparatus has an actuation member for controlling the rpm of a drive motor of the work apparatus. The actuation member is mounted in the handle and has a pressure surface for the fingers of a user hand. In an initial position, the actuation member protrudes with its pressure surface beyond the grip surface of the handle and, in a position for continuous operation of the motor, has dipped into the grip surface so that the pressure surface of the actuation member lies at the level of the grip surface. A recess extends in the longitudinal direction of the handle and is formed in the grip surface. The recess overlaps the pressure surface of the actuation member so that the actuation member is displaced into the handle via the recess to a boost position whereat the pressure surface lies within the grip surface.
