Definitions

  • the invention relates to a shaving part for dry shavers and hair clippers with slit-shaped hair inlet openings, which have a threading zone and a cutting zone covered by a moving shear part.
  • Such shaving parts can be shear combs made from flat material or produced by bending thin metal sheets with slots open on one side, but they can also be shaving foils in which the hair inlet openings are provided as circumferentially closed slots.
  • Shear parts of this type which are also mainly used to remove hair on soft, flexible skin areas, for example on the neck and armpits, are generally known (US Pat. No. 2,292,858).
  • the problem is that even small wrinkles on the skin get into the inlet openings in a wave shape and are injured in the cutting zone. In order to keep this effect as small as possible can. of course, the inlet openings in the shaving foil are made relatively small, but the shear effect is greatly impaired.
  • the invention has for its object to design a shear part of the type mentioned in such a way that on the one hand close-up shaving of hair is possible and on the other hand skin injuries or skin irritation are largely avoided.
  • the invention solves this problem in that in the direction of the threading path in front of the cutting zone there is at least one leading edge which is directed essentially transversely to the longitudinal axis of the slit-shaped hair inlet opening and around which the threading path is guided with at least two changes of direction.
  • the main advantage of the shaving part according to the invention is that body hair can be cut close to the skin without small skin wrinkles getting into the cutting zone of the shaving apparatus and thereby causing skin injury or skin irritation.
  • the skin flowing in through the threading zone is caught by the leading edge, which acts as a braking threshold, and is prevented from reaching the cutting zone directly by the double deflection of the threading path; as a result, the design known in the case of shear parts with hair inlet openings for skin irritation or skin injury which is inevitably kept is considerably reduced.
  • the threading zone is often made wider than the cutting zone; but since in this case skin wrinkles can penetrate better into the hair inlet openings, according to an advantageous embodiment of the invention the leading edge is formed by a projection which covers the cutting zone and a further leading edge offset from the first is provided, around which the threading path is guided like a labyrinth .
  • the two staggered leading edges and the four-fold change of direction of the threading path around both leading edges ensure with certainty that the skin wrinkles that have penetrated into the threading zone are slowed down and held back.
  • each hair inlet opening has two parallel cutting zones separated from one another by a web and having a common one extended threading zone in a symmetrical arrangement that two mutually directed projections covering the cutting zone are provided, and that the end flank of the web, as a further contact edge, is opposite the opening between the projections.
  • Fig..l the two interacting shear parts of a dry shaver or a hair clipper of any known type, which are used for cutting longer body hair, in particular for cosmetic purposes, are shown in section, namely the resting shear part 1, which essentially consists of a V- There is a bent sheet metal and is provided with slot-like hair inlet openings 2, and the moving shear part 4 provided with comb-like teeth 3.
  • the hair inlet openings 2, the detailed design of which is shown in FIGS. 2, 3 and 4 have a threading zone 5 and a cutting zone 6, which is swept by the moving shear part 4.
  • the threading zone 5 of the hair inlet opening 2 is not substantially wider than the cutting zone 6, but this is laterally offset with respect to the threading zone 5 with its longitudinal axis 7 to such an extent that the threading path 8 undergoes a two-way change of direction and Even before the cutting zone 6 - seen in the threading direction - a leading edge 9 directed transversely to the longitudinal axis 7 is created, which brakes wrinkled skin wrinkles and prevents them from reaching the cutting zone in a direct way.
  • the threading zone 5.1 is significantly expanded compared to the cutting zone 6.1.
  • a projection 11 directed transversely to the longitudinal axis 7.1, which extends to the opposite edge 12 so far that it covers the cutting zone 6.1.
  • the threading path 8.1 is guided around this projection 11 in a labyrinthine manner with a four-fold change of direction.
  • the projection 11 forms - seen in the threading direction - a first leading edge 13, which is assigned a second, offset leading edge 14 on the opposite edge 12, which is also directed essentially transversely to the longitudinal axis 7.1.
  • the hair inlet opening 2 has an extended threading zone 5.2 and two parallel cutting zone 6.2 separated by a web 15 in a symmetrical arrangement with respect to the longitudinal axis 7.2.
  • two mutually directed projections 18 and 19 are attached, which leave an opening 2o, the width of which corresponds approximately to the width of a cutting zone 6.2.
  • This opening 2o is located opposite the end face of the web 15 and forms, in addition to the leading edges 21 and 22 of the projections 18 and 19, a third leading edge 23.
  • the projections 18 and 19 block the direct path from the threading zone 5.2 into the cutting zones 6.2 and force a multiple change of direction of the threading path 8.2. Incoming wrinkles on the skin are braked and stopped at the three leading edges 21, 22 and 23.
