Patent ID: 7698819

Claim:
A shaving apparatus with a housing and at least one cutting unit which can be pivotably and resiliently pressed in with respect to the housing, said cutting unit comprising an outer cutter and an inner cutter that can be driven into rotation with respect to the former, said inner cutter being provided with cutting elements with cutting edges, while said outer cutter is provided with hair trap openings bounded by cutting edges for cooperating with the cutting edges of the cutting elements for the cutting of hairs, wherein during cutting of a hair a cutting force is exerted by the hair on the inner cutter, and a plane through the totality of cutting edges defines a cutting plane, said shaving apparatus being further provided with a drive device having a drive shaft for driving the inner cutter, which drive device during cutting of a hair exerts a driving force on the inner cutter, while the drive shaft exerts a prestress force in the direction of the outer cutter, wherein the drive device comprises only one coupling member that can be driven into rotation and that is provided with at least one driving surface, the drive shaft axially supporting the inner cutter by means of the coupling member and driving the coupling member into the rotation, the inner cutter is provided with at least one driven surface cooperating with the driving surface for exerting the driving force on the inner cutter, the direction of said driving force being substantially perpendicular to the driving surface and the driven surface, and snaps hooks are provided for fastening the coupling member to the inner cutter, wherein the snap hooks have arm portions and hook portions, the hook portions extending from the arm portions toward a center of the coupling member for hooking onto a coupling bush located around a center of the inner cutter, the coupling bush extending away from a carrier for the cutting elements, and wherein the arm portions, in a direction from the coupling member to the inner cutter, point toward the center of the coupling member.
