Definitions

  • the invention relates to a shaving apparatus having a foil with apertures of different shapes and a cutting member which is reciprocatable relative to the foil, the foil being provided with a regular pattern of round apertures alternating with oblong apertures.
  • Such a shaving apparatus is for example known from United States Patent Specification 2,900,719.
  • the shaving apparatus in accordance with the invention is characterized in that the longitudinal direction of the oblong apertures extends substantially in the direction of movement of the cutting member.
  • a preferred embodiment is characterized in that the round apertures are located at the vertices of a regular pattern of hexagons, an oblong aperture being situated within each hexagon.
  • 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 has a rectangular shape, a detail of said foil being shown on an enlarged scale in Fig. 3.
  • the foil 3 has round apertures 4 and oblong apertures 5.
  • the round apertures are located at the vertices of a regular pattern of quadrangles 16 which cover the entire area.
  • an oblong aperture 5 is formed whose longitudinal direction, represented by the longitudinal axis 17, extends in the directions of movement P of the cutting member 8.
  • the foil 3 is moved over the skin. Beard hairs which are caught in an aperture 4 or 5 and project into the interior of the shaving head are shaved off by the cutting action between the cutting edge 18 of a cutting element 9 and the edge 19 or 20 of an aperture 4 or 5.
  • the round apertures 4 are suitable for cutting short hairs, whilst the oblong apertures 5 are intended for longer hairs.
  • the ronnd and oblong apertures have a simple shape, which is favourable for reasons of manufacturing technology and consequently cost-saving.
  • FIG. 4 A particularly suitable pattern is shown in Fig. 4, the round apertures 4 being located at the vertices of the hexagons 21.
  • the longitudinal axes 22 of the oblong apertures 5 enclose an acute angle ⁇ under 45° with the direction of movement P.
  • the hexagons 21 are of irregular shape, i.e. at least two of the three diagonals 23, 24 and 25 have different lengths.
  • the oblong apertures 5 in the embodiment of Fig. 4 are approximately oriented in accordance with the longest diagonal 23, i.e. the longitudinal axis 22 encloses an acute angle with the diagonal 23 which is smaller than the angles and J enclosed by the longitidinal axis 22 and the diagonals 24 and 25 respectively.
  • round apertures are located at the vertices of a regular pattern of triangles, pentagons or other polygons.
