Embodiment Construction

[0021] figure 1 An embodiment of a shaving apparatus is shown consisting of nine separate modules: a foil frame assembly 10, a long hair cutter unit 12 which also functions as a skin mobilization assembly, a long hair undercutter 14, a long hair undercutter Device drive 16, low speed drive coupling 26, short beard undercutter 20, high speed drive coupling 22, drive cover 27 and base module 24.

[0022] The foil frame assembly 10 includes two short hair outer cutters 101, 102 mounted on the frame such that they are vertically but not axially movable. In the illustrated embodiment, these outer cutters are conventional shaving foils.

[0023] Such as figure 1 As shown, each short beard undercutter 20 comprises a generally tubular member having a plurality of transverse slots to provide the corresponding short beard outer cutter or foil 101, 102 with a positive bias during shaving. Multiple arcuate blades positioned together for a shearing action. Each short undercutter is mou...

Abstract

A shaving apparatus comprising a first shaving unit, including a first outer cutter (101,102) and a first undercutter (20) which cooperate together, a skin agitation member (12), a housing and a drive source (58) mounted in the housing. The outer cutter is mounted in a frame (10). The drive source is coupled to the first undercutter to provide oscillatory movement with respect to the frame at a frequency in the range 70 to 280 Hz. The drive source is also coupled to the skin agitation member to provide oscillatory movement at a frequency in the range 5 to 50 Hz. The first outer cutter is un-driven with respect to the frame.

Description

technical field [0001] The present invention relates to a dry shaving apparatus comprising: a drive source provided in a housing, at least one shaving unit having a short outer cutter and a short undercutter mounted for relative movement therebetween and an adjacent short A skin shaking member installed in the beard cutter unit. The invention also relates to a method for shaving. Background technique [0002] Although this specification mainly relates to a shaver having a linearly oscillating inner cutter extending longitudinally as described in U.S. Patent 5,185,926 (Locke) or 5,398,412 (Tanahashi et al.), The principle is also readily applicable to dry shavers with rotating inner cutters, as described in Japanese Patent Publication JP-A-5317 535 (Yamashita) or WO 96 / 02368 (Sterk et al.). [0003] Furthermore, the present application also relates to a dry shaving device having at least one shaving unit and a skin agitating member fixedly mounted on the shaver housing - US...
