Definitions

  • the invention relates to a roller shutter for a dry shaving apparatus, which is arranged on a dry shaving apparatus so as to be longitudinally displaceable, for selectively covering or releasing a sieve shear film of the dry shaving apparatus, and which consists of an elastic support and spaced-apart, stiff transverse webs and in groove-shaped guides provided on the dry shaving apparatus can be guided laterally on both sides.
  • a roller shutter known from DE-C-11 22 410 consists of a film which is provided with transverse webs which are spaced apart and extend over the central region of the film, leaving the lateral edge regions of the film free with which the roller shutter is guided laterally on both sides in the grooves provided on the dry shaver.
  • the invention has set itself the task of designing a roller shutter of the type mentioned in such a way that it has a stable structure as a whole, it being, with good stability in the transverse direction, well flexible in the longitudinal direction, in order to follow the course of a relatively strong, if necessary to be able to adapt curved screen shear foil.
  • this is achieved in that the transverse webs, seen in the longitudinal direction of the roller shutter, successively at least partially encased by the elastic support, extend over the entire width of the roller shutter and are provided at their ends with lateral rigid approaches with which the roller shutter in the Dry shaver provided groove-shaped guides can be guided laterally on both sides.
  • the roller shutter is particularly easy to guide, since the approaches reaching into the guides are as rigid and non-compliant as the crossbars, whereby the fact that these approaches, like the crossbars, are at a distance from one another means that the roller shutter even curved guides, as is the case in the area of the shear foil, can be followed perfectly.
  • cross bars are meandered by the carrier at least over their entire height. In this way, the connection of the crossbars to the carrier is particularly secure.
  • the carrier has at least one continuous strip running in the longitudinal direction of the roller shutter on the side of the transverse webs exposed by the carrier from the U-shaped surround.
  • the crosspieces are partially encompassed on both sides by the carrier, whereby a further improvement in the connection of the crosspieces to the carrier is obtained.
  • the strip runs in groove-shaped recesses provided on the exposed sides of the crossbars. In this way, anchoring of the crosspieces with the bar formed by the support is obtained, which results in a further improvement in the connection of the crosspieces with the support.
  • transverse webs as seen in the longitudinal direction of the roller shutter, are completely encased by the carrier, the sections of the carrier running between the mutually spaced transverse webs being designed as articulated weak points in the manner of film hinges.
  • the crossbars are non-detachably connected to the support, the sections of the support running between the crossbars again ensuring the flexibility of the roller shutter in the longitudinal direction.
  • the crossbars as seen in the longitudinal direction of the roller shutter, are completely encased by the carrier and the carrier is designed as a strip with flat wall surfaces.
  • the carrier In the case of transverse webs which are also non-detachably connected to the carrier, the carrier here has flat wall surfaces, which is important for the displaceability and, if appropriate external design of the roller shutter is advantageous.
  • the approaches are L-shaped and project from the crossbars transversely to the roller shutter.
  • the lateral guides for the roller shutters are offset from the course of the roller shutter itself, so that the side parts of the dry shaving apparatus in the area of the screen shaving film, in which the guides for the roller shutters are provided, do not have to protrude beyond the screen shaving film, so that the shaving is included the dry shaver is not hindered.
  • transverse webs which extend over the entire width of the roller shutter
  • the ends of the transverse webs are at least partially encased on the side by the carrier. In this way, the security of the connection of the crossbars to the carrier is also increased.
  • the last transverse web located at one end of the roller shutter, seen in the longitudinal direction of the roller shutter is designed as a widened grip part for moving the roller shutter. In this way, the handling of the roller shutter is easy and safe.
  • the carrier encasing the crosspiece designed as a grip part engages in grooves provided laterally on this crosspiece and extending transversely to the crosspiece. In this way, a particularly secure connection of the cross piece designed as a grip part to the carrier is obtained, which in particular is able to absorb forces occurring in the direction of displacement.
  • the invention further relates to a method for producing roller shutters designed according to the invention.
  • the aim of the invention is to provide particularly simple methods that can also be used well in series production.
  • the crossbars and the carrier are produced in a two-stage injection molding process, the crossbars being formed in the first process stage and the carrier being formed in the second process stage.
  • the knob-shaped projection molded onto the transverse webs in the first method stage is supported on the knob-shaped tool approach provided for the second method stage.
  • the knob-shaped approaches on the crosspieces do not protrude completely through the openings formed in the carrier, but only partially protrude into these openings, which may be desirable for design reasons, for example, but again the connection of the crosspieces with the carrier is consolidated, particularly in the direction of displacement of the roller shutter.

  • FIGS. 1 and 2 show a dry shaving apparatus which has a basic apparatus 1 and a shaving head frame 2 placed thereon.
  • the shaving head frame 2 is detachably held on the base apparatus in a manner not shown here, for example with at least one spring catch.
  • Such a shaving head frame is used to hold a curved screen shaving foil which is completely covered by a roller shutter 3 in FIGS. 1 and 2 in order to protect the screen shaving foil when the dry shaving apparatus is not in use.
  • a roller shutter 3 is arranged so as to be longitudinally displaceable on the dry shaving apparatus, wherein it is guided laterally on both sides in groove-shaped guides 4 and 5 provided on the dry shaving apparatus and indicated by dashed lines in FIGS. 1 and 2.
  • the roller shutter 3 can be pushed from the basic apparatus 1 over the shaving head frame 2 and the screen shaving foil, for which purpose the guides 4 and 5 for the roller shutter from the basic apparatus 1 continue in the side walls 6 and 7 of the shaving head frame 2, where they then start the curvature of the sieve shear foil is adjusted and curved.
  • the roller shutter is pushed back from its position shown in FIGS. 1 and 2 onto the basic apparatus 1 until it releases the screen shaving foil for shaving, as shown in FIG. 3, in the present case being pushed back so far is that the shaving head frame 2 is released so that it can be removed from the basic apparatus 2, for example for cleaning purposes or to replace the screen shaving foil 9 held on the longitudinal webs 8 of the shaving head frame 2.
  • roller shutter has the requirements that it has good stability in the transverse direction so that it can protect the screen shear film, but is also flexible in the longitudinal direction in order to be able to adapt to the course of a screen sheave which is also relatively strongly curved.
  • the roller shutter consists of an elastic support and with spaced transverse webs that are connected to the carrier.
  • FIGS. 4, 5 and 6 An exemplary embodiment of such a roller shutter 3 is shown in detail in FIGS. 4, 5 and 6.
  • the transverse webs 10, which are spaced apart from one another and extend over the entire width of the roller shutter, are rigid in themselves, which is due to their cross-sectional shape and choice of material so that the roller shutter has good stability in the transverse direction.
  • These transverse webs 10 are connected to a carrier 11 which is relatively thin and consists of an elastic material so that the roller shutter is flexible in the longitudinal direction.
  • the connection of the crosspieces 10 to the support 11 is done in such a way that the crosspieces, as seen in the longitudinal direction of the roller shutter, are successively embraced by the support on the U-shaped adjoining sides.
  • the cross webs 10 are meandered over their entire height by the carrier 11, as shown in FIG. 5.
  • a secure connection of the crosspieces to the carrier is obtained by enclosing the crosspieces over their entire height by the carrier as mentioned above.
  • the roller shutter as a whole forms on the side of the section 12 of the carrier 11 running between the crosspieces 10 together with the crosspieces 10 a continuous flat wall surface which is well suited as a bearing surface for the roller shutters on the dry shaving apparatus.
  • the transverse webs 10 are provided with lateral rigid projections 13 and 14, which in the present case are L-shaped and project from the transverse webs transversely to the roller shutter, in the direction away from the support 11.
  • These approaches 13 and 14 are used with their free ends for guiding the roller shutter in the groove-shaped guides 4 and 5 provided on the dry shaving apparatus. Because these approaches 13 and 14 as well as the transverse webs 10 are stiff, very good and safe guidance for the Get shutters. Since the approaches 13 and 14 as well as the crossbars 10 at a distance lie opposite one another, the roller shutter can also follow relatively strong curvatures of the guides 4 and 5, as can be the case in the area of the shear foil.
  • the position of the sections 12 forming the articulated weak points is selected at the level of the transverse webs 10, as a result of which articulated axes are formed for the rigid parts of the roller shutter, which allow the roller shutter to be positioned in a correct manner, the lateral ones Guides 4 and 5 to follow, since its rigid parts can pivot freely towards each other as needed.
  • the L-shaped design of the lugs 13 and 14 also ensures that the lateral guides 4 and 5 are offset from the course of the roller shutter, with the result that the side walls 6 and 7 of the cutter frame 2, in which the guides 4th and 5 run in the area of the screen shear film, do not have to protrude beyond the screen shear film, as can also be seen in FIG. 3.
  • the offset of the guides 4 and 5 with respect to the course of the roller shutter corresponds to the length of the legs of the L-shaped projections 13 and 14 projecting from the transverse webs 10. In this way there is no obstruction of shaving by side walls projecting beyond the level of the screen shear foil 9 6 and 7 of the shaving head frame 2.
  • the last transverse web, seen in the longitudinal direction of the roller shutter, at one end of the roller shutter, which is furthest away from the screen shaving foil when the roller shutter is located on the dry shaving apparatus, is designed as a widened handle part 15. Furthermore, this as a handle part 15 removable Dete transverse web laterally transverse to it, provided with undercuts grooves 16, in which it encases the carrier 11 engages. In this way, a particularly secure connection of the handle part to the carrier is obtained, which is able to absorb forces acting in particular in the direction of displacement, such as arise when handling the roller shutter.
  • the support has on the side of the crossbars exposed by the U-shaped surround by the support 10 three spaced bars 17, 18 and 19 lying at a distance from one another and running in the longitudinal direction of the roller shutter, as can be seen in FIG. 6.
  • these strips run in groove-shaped recesses 20, 21 and 22 provided on the exposed sides of the crosspieces 10, which results in a secure anchoring of the crosspieces 10 with the strips 17, 18 and 19 of the carrier 11.
  • the strips 17, 18 and 19 of the support 11 thus, in cooperation with the crossbars 10, by partially gripping the support on both sides, result in a strut of the roller shutter which strengthens the connection of the crossbars to the support and increases the stability of the entire roller shutter .

In this way, an even better positioning of the crosspieces 10 in the tool for the second process stage is achieved and the connection of the crosspieces 10 to the carrier 11 is additionally strengthened, in particular in the direction of displacement of the roller shutter.
  • the roller shutter shown in Figures 9, 10 and 11 is constructed essentially the same as the roller shutter shown in Figures 4, 5 and 6, but is produced by another two-stage injection molding process, but in the again in the first process stage the crossbars 10 are formed and in the second process stage the carrier 11 is formed.
