  • Patent number: 8739894
    Abstract: The invention relates to a handheld work apparatus having a handle. A throttle trigger and a throttle trigger lock are arranged on the handle. An operating-mode selector having an off position, an operating position and a starting position is provided. The selector, trigger lock and the trigger are pivotally mounted. A first latching element is provided on the selector and a second latching element is provided on the trigger element, which coact in the starting position of the selector and the starting position of the trigger and hold the trigger in its starting position. To ensure that the starting position of the selector can only be engaged when the trigger is actuated, the second latching element lies outside of the pivot path of the first latching element in the non-actuated position of the trigger.

  • Patent number: 7963266
    Abstract: A starter device for an internal combustion engine (10) has an actuating device and an entrainer (24) can be coupled to the crankshaft (13) of the engine (10). The entrainer (24) and the actuating device are rotatably journalled about a rotational axis (14). The entrainer (24) and the actuating device are connected to each other via a damping spring (23). The damping spring (23) is connected with a first end (26) to the actuating device and with a second end (27) to the entrainer (24). The entrainer (24) and the actuating device have respective supports (21, 42). The damping spring (23) is mounted on the outer periphery of the two supports (21, 42). In the direction of the rotational axis (14), a disc (22) is mounted between the two supports (21, 42) in order to avoid the situation that the damping spring (23) can force itself into a gap between the two supports (21, 42) which gap can arise during operation.
