Definitions

  • Figure 1 is a partial isometric view of a blade unit embodying the invention
  • the elements 9 are connected to the front wall 8 by respective stems 12 which are bent through 90° adjacent the elements 9 so that the elements define an upwardly facing engagement surface for engaging the skin during shaving.
  • the trailing end parts 14 of the elements are downwardly inclined from the skin contacting surface at an angle in the range of 40° to 60°.
  • the support stems 12 are relatively narrow defining intervening gaps 15 of substantially greater width than the stems themselves so that hairs will tend to pass into the gaps rather than being flattened against the skin by the stems.
  • the gaps 15 lead into the slots 10, the transition between the gaps and slots being shaped to funnel the hairs into the mouths of the slots.
  • Hairs which fail to enter the slots 10 can enter these additional slots 30 which like the slots 10, are confined between edges 16 of reduced thickness so that the edges notch into the hairs and cause them to be pulled by the downwardly inclined tail parts 19 of the prongs in the same way as the hairs passing through the slots 10 are pulled.
  • the hair pulling member could for example take the general form of any of the embodiments of the skin engaging members described in WO 95/29043, the contents of which are incorporated herein by this reference, always provided that the elements which provide the skin engagement surface have slot edge profiles so that the edges notch into the hairs, and these elements are extended by downwardly inclined rear parts which are directed away from the skin engaging surface.

Abstract

Cet ensemble lame pour rasoir de sûreté comprend un élément (7) destiné à tirer les poils situés immédiatement devant le bord coupant d'une lame (6) et présentant des fentes (10) à travers lesquelles passent les poils. Ces fentes sont délimitées par une série d'éléments (9), lesquels présentent des bords délimitant les fentes (10) et formés de manière à enserrer les poils au moment de leur passage à travers les fentes. Des portions arrière de fuite (14) des éléments (9) sont inclinées pour guider les poils enserrés, afin que ceux-ci suivent un trajet conçu pour les étirer depuis la peau, juste avant d'être coupés par la lame.
