  • Patent number: 8950073
    Abstract: A chain sharpening device arranged to sharpen a saw chain. The device comprises a housing (110), arranged to be detachably mounted on the guide bar (3), a sharpening element (140) selectively displaceable relative to the housing between a resting state and a sharpening state, an actuator (150), selectively displaceable between an inactivated state and an activated state, which actuator is connected to the sharpening element and arranged to selectively bring the sharpening element from the resting state to the sharpening state, a first biasing member (160) operatively connected to the actuator and arranged to bias the actuator towards its inactivated state, a second biasing member (170), operatively connected to the sharpening element and arranged to enable relative movement between the actuator and the sharpening element when the sharpening element is in the sharpening state, so as to delimit a force with which the sharpening element (140) can be pressed towards the saw chain.
