Definitions

  • the invention relates to a dry shaving apparatus with a long-hair cutter, which is designed as a plate-shaped unit and is arranged displaceably on a housing shell of the dry shaving apparatus between at least two positions, the unit being inserted into an opening provided on the housing shell and having two lateral guide sections parallel to one another and to the direction of displacement , which each cooperate with a corresponding guide provided on the housing shell.
  • the invention has set itself the task of creating such a mounting option for the unit forming the long-hair trimmer in a dry shaving apparatus of the type mentioned that it is captively combined with a housing shell of the dry shaving apparatus without additional means, but again if necessary, but also without additional means , can be easily removed from the housing shell.
  • this object is achieved according to the invention in that the guides on the housing shell are arranged in the region of one end of the opening, viewed in the direction of displacement, and in the region of the other end of the opening a structural unit bridging them transversely to the direction of displacement from the inside of the housing shell there is a web and that at least one resilient tab extending in the direction of displacement and projecting into the interior of the housing shell in the direction of the web is provided on the structural unit, the normal distance of the free end of the tab measured in the direction of displacement to the ends of the guide sections on the structural unit facing away from this free end of the flap is greater than the clear width between the web and the ends of the guides on the housing shell facing it.
  • the resilient tab together with the web forms a lock against unintentional detachment of the assembly from the housing shell after the insertion of the guide sections on the assembly into the guides on the housing shell, since the displacement path of the assembly so far when the tab rests on the web it is limited that their guide sections can no longer leave the guides on the housing shell.
  • the assembly of the assembly on the housing shell is very simple.
  • the module is pivoted into the opening after insertion and pressed with the tab against the web until it is pressed down so far that the module with its guide sections can be pushed into the guides on the housing half, the tab then being pushed in during this frees itself from the dock and straightens up, which has already resulted in the captive union of the housing shell and the structural unit.
  • no further aids are required for this, so that, in particular, series production can be carried out simply and inexpensively.
  • the deliberate detachment of the assembly from the housing shell is just as simple, since for this purpose only the tab is pressed down to free it from the web and then the assembly with its guide sections has to be pushed out of the guides on the housing shell, for which no further aids are also required.
  • the guide sections on the structural unit and the guides on the housing shell there are various possibilities for the design of the guide sections on the structural unit and the guides on the housing shell, such as channels on the structural unit and strips on the housing shell.
  • the guide sections on the structural unit are formed by projecting strips which run alongside the opening along the inner wall of the housing shell, and the guides on the housing shell by cantilevering from this, the strips from the Hook-shaped approaches overlapping the inside of the housing shell are formed.
  • the web has lateral base parts which extend next to the opening to the inner wall of the housing shell, and the clear width between the web and the ends of the guides on the housing shell facing it is greater than the length of the strips forming the guide sections on the structural unit.
  • FIG. 1 shows a dry shaving apparatus with a long hair cutter from a narrow side.
  • Fig. 2 the dry shaving apparatus according to Fig. 1 is shown from a broad side.
  • 3 shows a plan view of the inside of the housing shell of the dry shaving apparatus provided for carrying the long hair cutter.
  • the housing shell of FIG. 3 is shown in section along the line IV-IV in Fig. 3.
  • Fig. 5 shows schematically the assembly forming the long hair trimmer in a top view.
  • Fig. 6 the assembly of Fig. 5 is shown in section along the line VI-VI in Fig. 5.
  • Fig. 7 shows in the representation of FIGS.
  • FIG. 8 shows the structural unit in the position pivoted out of the position according to FIG. 7 towards the housing shell.
  • FIG. 9 shows a top view of the inside of the housing shell of the structural unit combined with the housing shell, the latter being in the position pushed out of the housing shell.
  • 10 shows the housing shell together with the assembly according to FIG. 9 in section along the line X-X in FIG. 9.
  • FIG. 11 shows the assembly in the position shown in FIG. 9 in its position pushed into the housing shell.
  • FIG. 12 shows the housing shell together with the structural unit according to FIG. 11 in section along the line XII-XII in FIG. 11.
  • 1 denotes a dry shaving apparatus which has two housing shells 2 and 3, on which a shaving head 5 carrying a curved sieve shaving foil 4 is placed.
  • a bottom knife interacts with this screen shear film 4 in the usual way and can be driven back and forth by a motor accommodated within the housing shells.
  • the dry shaving apparatus 1 has a long hair cutter, the knives of which are denoted by 6 and which, as a whole, is designed as a plate-shaped unit 7 which is arranged on the housing shell 3 so as to be displaceable between two positions. 1 and 2, the structural unit 7 is shown in its position pushed into the housing shell 3. In FIG. 1, the position of the structural unit 7 pushed out of the housing shell 3 is also indicated with dotted lines.
  • the design of the long-hair trimmer in detail whose knives usually consist of a stationary toothed knife and a toothed counter-knife interacting with it, which can be driven back and forth by the motor of the dry shaving apparatus, is not shown here for the sake of simplicity.
  • the assembly 7 is inserted into an opening 8 provided on the housing shell 3 and can be displaced in this between the two aforementioned positions in the direction of displacement indicated by a double arrow 9.
  • the structural unit has two lateral guide sections 10 and 11 which are parallel to one another and to the direction of displacement 9 and which each cooperate with a corresponding guide 12 or 13 provided on the housing shell 3,
  • the housing shell 3, viewed in the direction of displacement 9, has hook-shaped lugs 14 and 15 in the region of one end of the opening 8, which, together with the inner wall 16 of the housing shell 3 running next to the opening 8, form the guides 12 and 13 provided thereon.
  • a web 17 bridging it transversely to the direction of displacement 9 is provided.
  • the guide sections 10 and 11 are formed by projecting strips 18 and 19 which, when the structural unit 7 is mounted on the housing shell 3, run alongside the opening 8 along the inner wall 16 of the housing shell 3, the hook-shaped projections 14 and 15 then overlap the strips 18 and 19 from the inside of the housing shell.
  • a resilient tab 20 projecting in the direction of displacement 9 and projecting into the interior of the housing shell in the direction of the web 17 is provided on the structural unit 7.
  • the dimensions here are such that the normal distance a, measured in the direction of displacement 9, of the free end 21 of the tab 20 to the ends 22 and 23 of the guide sections 10 and 11 on the assembly 7 facing away from this free end of the tab is greater than the clear width b between the web 17 and the ends 24 and 25 of the guides 12 and 13 on the housing shell 3 facing it.
  • the web 17 has lateral base parts 26 and 27 which extend next to the opening 8 to the inner wall 16 of the housing shell 3.
  • the clear width b between the web 17 and the ends 24 or 25 of the guides 12 or 13 on the housing shell 3 facing it is selected to be greater than the length c of the strips 18 or the bars 18 or 11 forming the guide sections on the structural unit 7.
  • a stop 28 is also provided on the housing shell 3, against which the structural unit 7 comes to rest when it assumes its position pushed into the housing shell 3.
  • the assembly of the structural unit 7 on the housing shell 3 will now be explained.
  • the assembly 17 is inserted into the opening 8 of the housing shell 3 from the inside with the long hair cutter ahead and the tab 20 facing the web 17, the ends 29 and 30 facing the knives 6 of the long hair cutter the projecting strips 18 and 19 come to rest on the inner wall 16 of the housing shell 3.
  • the assembly 7 is then shifted towards the web 17 until the ends 29 and 30 of the projecting strips 18 and 19 also come to rest on the base parts 26 and 27 of the web 17, whereby pivot points are formed around which the assembly 7 can be pivoted counterclockwise to the web 17 until the projecting resilient tab 20 is pressed down.
  • the guide sections 10 and 11 formed on the strips 18 and 19 on the structural unit 7 can no longer leave the guides 12 or 13 on the housing shell 3, because, as stated above, the normal distance a of the free measured in the direction of displacement 9 End 21 of the flap 20 to the ends 22 and 23 of the guide sections 10 and 11 on the structural unit 7 facing away from this free end 21 of the flap 20 is greater than the clear width b between the web 17 and the ends 24 and 25 facing it Guides 12 and 13 on the housing shell 3, as can also be seen from FIGS. 9 and 10.
  • the assembly 7 is thus completely securely united with the housing shell 3 and cannot be unintentionally detached from it.
  • the assembly 7 of the housing shell 3 are separated again, so this is also easily possible without additional aids.
  • the assembly 7 is brought into its position pushed out on the housing shell 3, which is shown in FIGS. 9 and 10.
  • the flap 20 is then pressed down on the structural unit 7 with the finger of one hand and this is then displaced in the direction of displacement 9 in the direction further towards the web 17, the flap 20 again coming to rest under the web 17.
  • This displacement of the assembly 7 continues until the ends 22 and 23 of the guide sections 10 and 11 on the assembly 7 are released from the guides 12 and 13 on the housing shell 3, whereupon the assembly 7 clockwise within the opening 8 of the housing shell 3 pivoted and then removed from this.
  • the pivoting of the assembly 7 takes place practically by itself because the tab 20 pushes the assembly 7 away from the web 17 under its resilient action.
