'A hand-operated tool and starting device for a hand-guided implement'

摘要

A hand-operated tool has an internal combustion engine (11) and a starting device (8) for the internal combustion engine (11). The starting device (8) has an actuating device (46) and a coupling device (47) for connection to a crankshaft (10) of the internal combustion engine (11). The actuating device (46) is about an axis of rotation (44) is rotatably mounted. As a helical spring (17) is a damping element in the direction of action between the actuating device (46) and the coupling device (47) is arranged. The helical spring (17) has at its relative to the axis of rotation (44) radially outer region of a contact surface (43). Into the interior of the helical spring (17) projects, at least one connection piece (21, 35). The connection piece (21, 35) has at its relative to the axis of rotation (44) radially outer region, a support surface (41, 42). In order to ensure a pleasant course of the actuating force, it is provided that between the contact surface (43) and the supporting surface (41, 42) in the unoperated state of the starting device (8) in at least one section of the helical spring (17) a distance (a, b, c) is formed which, in the direction of the axis of rotation (44) of the actuating device (46) is increased.
