Definitions

  • the invention relates to a shaving apparatus having a cutting member which is reciprocatable relative to a foil, the foil being provided with a regular pattern of round apertures and oblong apertures.
  • Such a shaving apparatus is for example known from US-A-2.900.719.
  • the shaving apparatus in accordance with the invention is characterized in that the round apertures are located at the vertices of a regular pattern of hexagons, an oblong aperture being located witt ⁇ r( each hexagon, the longitudinal axis of each oblong aperture being parallel with or inclined at an angle of under 45° to the direction of reciprocation of the cutting member.
  • the DE-A-947.685 shows foil patterns with oblong apertures arranged with different angles of inclination between the longitudinal axis of an aperture and the direction or reciprocation of the cutting member.
  • the combination of round apertures and oblong apertures which permits a high ratio between the total area of the apertures and the working area of the shear foil, i.e. the area which will be swept by the cutting member in the operation of the shaving apparatus, is not known from this DE-patent.
  • the oblong apertures are intended for catching long hairs, whereas the round apertures are suitable for catching short hairs.
  • the shaving apparatus in accordance with Figures 1, 2 and 3 comprises a housing 1 with a detachable shaving head 2.
  • the shaving head 2 is provided with a foil 3 with apertures 4, 5.
  • said head is provided with hook-shaped projections 6 which engage with corresponding openings 7 at the edge of the foil.
  • a cutting member 8 which is reciprocatable relative to the foil is located at the inner side of the foil.
  • the cutting member 8 is provided with arcuate cutting elements 9 which at the ends are secured to the strips 10. At the ends these strips 10 are interconnected by the transverse members 11, so that a frame 12 is obtained which is the base for the cutting member.
  • This frame 12 is provided with a pin 13 for the coupling of the cutting member 8 to the vibrator motor 15 via the drive spindle 14.
  • the cutting member 8 is reciprocated in the directions P relative to foil 3.
  • the foil 3 is moved over the skin. Hairs which are caught in an aperture 4 or 5 and project into the interior of the shaving head are shaved off by the shearing action between the cutting element 9 and the foil 3.
  • the round apertures 4 are suitable for catching short hairs, whilst the oblong apertures 5 are intended for longer hairs.
  • the foil 3 has a rectangular shape, a section of said foil being shown on an enlarged scale in Fig. 3.
  • the round apertures 4 are located at the vertices of a regular pattern of hexagons 16 which cover the entire area. Within every hexagon 16 an oblong aperture 5 is formed whose longitudinal direction is represented by the longitudinal axis 17.
  • the longitudinal axes 17 of the oblong apertures 5 enclose an acute angle a under 45° with the direction of reciprocation P of the cutters.
  • the hexagons 16 are of irregular shape, i.e. at least two of the three diagonals 18, 19 and 20 have different lengths.
  • the oblong apertures 5 are approximately oriented in accordance with the longest diagonal 18, i.e. the longitudinal axis 17 encloses an acute angle f3 with the diagonal 18 which is smaller than the angles y and 5 enclosed by the longitudinal axis 17 and the diagonals 19 and 20 respectively.
