Abstract
Abstract An electric shaver with an elongated long hair trimmer which is adjacent to one exposed longitudinal edge of the shear foil and is pivotable with reference to the head frame of the shaver between a concealed and an exposed or operative position. The movable clipping element of the trimmer is automatically coupled to the drive for the cutter which cooperates with the shear foil when the trimmer is pivoted to its exposed position. The trimmer is pivotable along an axis which is parallel to the adjacent exposed longitudinal edge of the shear foil. A spring propels the trimmer to the exposed position in response to actuation of a knob which disengages a latch serving to normally hold the trimmer in the concealed position in which the trimmer does not interfere with access to the adjacent portion of the shear foil.
