Brake assembly for power-driven hand-held cutting device

摘要

A brake assembly (1) for a hand-held power-driven cutting device (2) is provided comprising a movably arranged lever (14), at least being movable between a first- and a second position, a brake member (16), and a brake element (20) connected to or forming one unit with a rotatable part (22) of a transmission of the cutting device (2), wherein the brake member (16) is movable between a non-activated position and an activated position, and wherein the brake member (16) is arranged to engage with the brake element (20) in the activated position to prevent rotation of the rotatable part (22). The brake assembly (1) further comprising a holding mechanism (23) arranged to hold the brake member (16) in the non-activated position when the lever (14) is in the first position, and a first resilient element (18) arranged to bias the brake member (16) towards the activated position, and wherein the brake member (16) is arranged to be released from the holding mechanism (23) as a response to the lever (14) coming into the second position, and wherein when released the brake member (16) is adapted to be forced towards the activated position by means of the first resilient element (18), and wherein the brake member (16) is arranged to engage with a structure (34) of the brake element (20) in said activated position so as to prevent rotation of the brake element (20).
