Definitions

  • the invention relates to a shaving head for a dry shaving apparatus having a shaving head frame which has two longitudinal webs and two side walls and which carries an arched screen shaving foil which is provided in the region of its two longitudinal edges, which optionally carry reinforcing strips, with at least two spaced-apart openings with which they is hooked into hooks projecting from the two longitudinal webs, the hook ends pointing away from the curvature of the screen shear foil.
  • Such shaving heads are used in commercially available dry shavers which have a reciprocating bottom knife which interacts with the shaving foil of the shaving head.
  • the invention has set itself the goal of eliminating the aforementioned difficulties and still ensuring a secure hold of the screen shaving film on the shaving head frame with the simplest possible design of the shaving head frame of the shaving head and a simple assembly of the screen shaving foil on the shaving head frame.
  • the screen shaving foil is provided on its outer side facing the longitudinal webs of the shaving head frame in the region of its two longitudinal edges with at least one projecting projection, which is at a distance from the free end of the adjacent longitudinal web that is smaller than the depth of is the projecting hook of the longitudinal webs, and which projects with its height at least into the dimension of the wall thickness of the longitudinal struts in the region of its free ends.
  • the protruding projections on the screen shear film limit their possible adjustment path, so that they cannot easily slide off the hooks. If you want to deliberately remove the screen shaving foil from the shaving head frame, you press the protruding lugs from the outside by hand, which causes the screen shaving foil to bulge inwards and thereby detach from the hooks.
  • the installation of the sieve shaving foil on the shaving head frame is also very simple, since apart from the hooks, which correspond to the openings in the sieve shaving foil, there are no further projections on the longitudinal webs of the shaving head frame, so that they can be used without hindrance their openings can be hooked into the hook.
  • the shaving head frame itself is of simple construction, since in addition to the hooks no further projections have to be provided on it.
  • the projections provided in the area of the two longitudinal edges of the screen shear foil are designed as strips running parallel to the free ends of the adjacent longitudinal webs of the shaving head frame. Such strips certainly limit the possible adjustment path of the screen shear film on the shaving head frame and offer a good contact surface for deliberately detaching the screen shear film from the shaving head frame, and they also result in a reinforcement of the screen shear film in the region of its longitudinal edges.
  • the vertical extension of the projecting projections provided in the area of the two longitudinal edges of the screen shear film is substantially equal to the wall thickness of the longitudinal webs in the area of their free ends.
  • the possible adjustment path of the screen shear film on the shaving head frame is particularly reliably limited, since a relatively strong curvature of the screen shear film inside is necessary in order to detach it from the hooks, which then certainly cannot happen unintentionally.
  • FIG. 1 shows a shaving head in cross section.
  • Fig. 2 shows the shaving head frame according to Fig. 1 in plan view of one of the longitudinal webs of the shaving head frame, wherein according to a first embodiment the protruding lugs on the screen shear film are formed as strips.
  • FIG. 3 shows in the representation of FIG. 2 a second exemplary embodiment, according to which the projecting projections on the screen shear foil are designed as cylinders.
  • the shaving head shown in FIGS. 1 and 2 has a shaving head frame 1 which carries a curved screen shaving foil 2.
  • the shaving head frame 1 consists of two longitudinal webs 3 and 4 and two side walls 5 and 6.
  • the screen shear foil 2 is provided in the region of its two longitudinal edges with a reinforcement strip 9 or 10, in each of which two openings are provided at a distance from one another, of which an opening 11 or 12 is again visible in FIG. 1 .
  • openings 11 and 12 and the hooks 7 and 8 on the longitudinal webs 3 and 4 are corresponding to each other, so that the screening shear film can be hung with these openings in the hooks, it then runs arched and below the through the curvature caused tension with the outside facing the longitudinal webs of the shaving head frame on the inner walls of the respective longitudinal webs 3 and 4 laterally.
  • reinforcement strips 9 and 10 are not absolutely necessary, but the openings can also be provided directly on the screen shear film.
  • the screen shaving foil 2 is now on its outer side facing the longitudinal webs 3 or 4 of the shaving head frame 1 in the area of its two longitudinal edges, which are to be understood as those areas which laterally adjoin the perforated field of the screen shaving foil used for shaving, each with a projecting attachment 13 or 14 provided.
  • projections 13 and 14 have a distance a 7 from the free end 15 and 16 of the adjacent longitudinal web 3 and 4 of the shaving head frame 1 which is smaller than the depth t of the hooks 7 and 8 projecting from the longitudinal webs 3 and 4 Since the shoulders 13 and 14 are arranged on the outside of the screen shear foil facing the longitudinal webs 3 and 4 of the shaving head frame, with which they are supported on the inner wall of the longitudinal web in question, they jump with their vertical extension into the dimension range w of the wall thickness the longitudinal webs 3 and 4 in the region of their free ends 15 and 16 respectively.
  • the screen shaving foil 2 is held securely on the shaving head frame. If, for example, pressure is exerted on the curvature of the screen shear film from the outside, the screen shear film together with its reinforcement strips 9 and 10 will endeavor to be adjusted along the inner walls of the adjacent longitudinal webs 3 and 4 in the direction of the hooks 7 and 8 . However, there is a limit to such an adjustment because the projecting projections 13 and 14, due to their height extension at the free ends 15 and 16, respectively, extending into the dimensional range w of the wall thickness of the longitudinal webs 3 and 4 in the region of their free ends 15 and 16, respectively. Strike 16 of the relevant longitudinal webs 3 or 4.
  • the distance a between the projecting lugs 13 and 14 relative to the free ends 15 and 16 of the adjacent longitudinal webs 3 and 4, via which an adjustment of the screen shear film is possible, is selected to be smaller than the depth t of the hooks 7 projecting from the longitudinal webs or 8, it is achieved that the openings 11 and 12 can not get free from the hooks 7 and 8, because they are still within the hook areas.
  • the screen shaving foil 2 cannot slide off the shaving head frame 1.
  • the reinforcing strips 9 and 10 are pivoted about their support within the hooks 7 and 8, with the sieve shear foil 2 being warped inwards.
  • the projecting projections 13 and 14 increasingly leave the dimensional range w of the wall thickness of the longitudinal webs 3 and 4 in the region of their free ends 15 and 16, with respect to their vertical extension, and finally the projections 13 and 14 of these free ends 15 or, 16 are optional.
  • the openings 11 and 12 can be released from the hooks 7 and 8, as a result of which the screen shaving foil 2, because its adjustment path is no longer limited, is released from the shaving head frame 1.
  • a slight pressure on the lugs 13 and 14 is enough to To achieve loosening of the sieve shear foil from the shaving head frame, since this process is supported by the striving of the arched sieve shear foil to relax.
  • the screen shaving foil is securely held on the shaving head frame on the one hand and can be easily detached from it on the other hand.
  • the installation of the sieve shaving foil on the shaving head frame also poses no difficulties and can be carried out from both the top and the bottom of the frame. If you choose the assembly from the top of the frame, the screen shear film is inserted with one longitudinal edge first into the shaving head frame and hung with the openings in the hooks of the relevant longitudinal web, after which the screen shear film is then warped and inserted with the other longitudinal edge first into the shaving head frame and also with which openings are hooked into the hooks of the other longitudinal web.
  • the screen shaving foil When assembling from the underside of the shaving head frame, the screen shaving foil is first arched and inserted with the curvature first into the shaving head frame and then hung with the openings in the hooks. Since the inner walls of the longitudinal webs 3 and 4 are flat except for the hooks 7 and 8, which correspond to the openings 11 and 12 on the screen shear film and are therefore not a hindrance when mounting the screen shear film on the shaving head frame, the screen shear film can be used without Disability can be easily hooked into the hooks 7 and 8 with their openings 11 and 12, respectively.
  • the height extension of the projecting projections 13 and 14 is selected such that it is essentially equal to the wall thickness w of the longitudinal webs 3 and 4 in the region of their free ends 15 and 16. In this way, a particularly reliable limitation of the possible adjustment path of the screen shear film 2 is achieved, since the projecting projections 13 and 14 reliably act on the free ends 15 and 16 of the longitudinal webs 3 and 14 when the screen shear film is curved from the outside.
  • FIG. 2 shows an embodiment in which these projections 13 and 14 are designed as strips which run parallel to the free ends 15 and 16 of the adjacent longitudinal webs 3 and 4 of the shaving head frame.
  • Such an extension 13 is visible in FIG. 2, which is designed here as a strip that extends over the entire length of the sieve shear foil 2.
  • FIG. 3 shows an exemplary embodiment in which two protruding projections are provided in the area of each longitudinal edge of the sieve shear foil 2 and are spaced apart from one another as seen in the longitudinal direction of the sieve shear foil 2 and are formed by cylinders with a circular cross section. 3 shows two of these approaches 13.
  • another cross-sectional shape would also be possible, such as elliptical or prismatic.
  • more than two projecting projections such as three or four, could also be provided in the area of each longitudinal edge of the screen shaving foil. Even with such embodiments, the screen shaving foil is securely held on the shaving head frame, the screen shaving foil again simply being mounted on the shaving head frame or by him can be solved.
  • the sieve shear foil is also to be provided with reinforcement strips in the area of its longitudinal edges, then for example the reinforcement strips can be made to extend into the area of the projections and the rivets can be carried out in such a way that they simultaneously ver Connect the reinforcement strips and the lugs to the sieve shear film, the sieve shear film then coming to lie between the approaches and the reinforcement strips, as shown in FIG. 1.
  • the approaches are made of plastic, they can be ultrasonically welded to the screen shear film or crimped onto the screen shear film under the influence of heat.
  • the sieve shear film is also to be provided with reinforcement strips made of plastic in the region of its longitudinal edges, the projections also being made of plastic, the projections and the reinforcement strips can also be injection molded directly onto the sieve shear film as one-piece parts.
