Embodiment Construction

[0018] Figure 1-3 The shaving apparatus shown in has a shaving unit comprising three shaving heads 1 and a cover in which the shaving heads 1 are suspended. Each shaving head 1 has a driven cutting member 10 and a stationary outer cutting member or shear plate 12 with hair entry holes 13 . The cutting members 10, 12 are elastically suspended such that the cutting members 10, 12 can be pressed into a position such that the outer surface 2 of the outer cutting member 12 is substantially flush with the surface of the cap. This defines the maximum contact pressure normally applied in use between the outer blade 12 and the skin 8 . The movable blade 10 can be driven by a motor (not shown) in a known manner so as to move along the inner surface of the outer blade 12 so as to cut off the hairs 11 caught in the hair entry holes 13 by the cooperation of the cutting members 10,12.

[0019] Adjacent to the outer blade 12 a hair guide 3 protrudes from the guide face 4 . The guide 3 de...

Abstract

A shaving unit has at least one cutter (10, 12) for cutting hairs (11), a guide surface (4) extending closely adjacent the cutter or cutters (10, 12), and hair guides (3) projecting from the guide surface (4). The hair guides (3) bound channels (5) extending from an area spaced from the cutter or cutters (10, 12) towards the cutter or cutters (10, 12), and the hair guides each have a skin contact surface (6) facing away from the guide surface (4) and a surface (16) facing the guide surface (4), wherein the skin contact surface (6) is at least partially round and meets the surface (16) facing the guide surface (4) along a hair catching edge (7).

Description

technical field [0001] The invention relates to a shaving head comprising at least one blade and a hair guide. Background technique [0002] Shavers are well known in the art, both with safety razors and electric razors, with hair guides for catching hairs and keeping them in the direction of the hair protruding from the skin. direction, allowing the blade to cut hair reliably. [0003] Electric hair cutting devices, such as shavers and trimmers, generally have a housing containing a motor for driving a rotatable or vibrator in one or more shaving heads at the end of the housing. movement of the blade. Hairs protruding into the apertures of the substantially stationary outer blades are severed between the outer blades and the inner blades which move along the outer blades. [0004] In US Pat. No. 4,310,968 there is disclosed a shaver equipped with a brush for straightening hair to be shaved. The brush has bristles with hooked ends for combing hair. By moving the shaving...
