Abstract
The dry electric shaver includes a pair of movable cutter blocks reciprocatively movable by a drive bar with respect to a fixed perforated comb. The cutter blocks are coupled to the drive bar by a unitary one-piece plastic cutter support having a central body engageable with the drive bar and having coaxial torsion bars extending from the opposite sides thereof, the distal ends of the torsion bars being respectively integral with the midpoints of elongated arms disposed substantially perpendicular to the torsion bars. Each arm carries at each of its ends an attachment portion having an opening receiving a stake on the cutter block in press-fitted engagement. The cutter support is sufficiently resilient and flexible to accommodate varied movements of the cutter blocks independently of each other, while remaining relatively stiff in the direction of movement of the drive bar. A bias spring urges the cutter support and the supported cutter blocks toward shearing engagement with the comb.
