  • Patent number: 10814469
    Abstract: A power tool has a handle operatively connected with vibration damping across a vibration gap to a drive motor with throttle element. An actuating device on the handle actuates the throttle element pivotably supported in a housing. A coupling element bridging the vibration gap connects actuating device to throttle element. The actuation movement of the actuation device is transmitted as rotation about an axis transverse to the vibration gap. An intermediate element is pivotably supported on an actuating element connected to the throttle element. The coupling element acts on the intermediate element and, over part of the actuation movement, contacts a contact region of the intermediate element. A guide for the intermediate element changes a position of the contact region relative to the housing based on a rotational position of the actuating element by changing a pivot position of the intermediate element relative to the housing.

  • Patent number: 10215131
    Abstract: A power tool has an internal combustion engine with a carburetor with choke element pivotably arranged therein. A starter device with an actuating element has an operating position, off position, and at least one start position. A coupling element connects the actuating element with a choke actuating lever. The actuating element, upon adjustment from operating position into the at least one start position, moves the choke element into its start position. The connection between actuating element and choke actuating lever has a relative movement device which, in one position of the choke element, enables movement of actuating element relative to choke actuating lever. A holding device with guide contour is secured on the carburetor housing. In a start position of the choke element, the guide contour prevents movement of the actuating element relative to choke actuating lever from its start position into the operating position.
