Definitions

  • the present invention relates to the field of Wristwatches. It concerns a wristwatch with a clockwork, which is surrounded by a housing and by means of an outside crown rotatably attached to the case via a through the Housing guided shaft is actuated, with the crown as sealing screw-in crown is formed.
  • Such a wristwatch is e.g. from the publication CH-A3-682 968 known.
  • Wristwatches wound with a crown are adjusted or can be operated in any other way Execution of the wave connected to the crown by the Watch case a weak point in terms of tightness against dust, water and other environmental influences. So you have proposed a variety of solutions in the past where the crown is screwable and in screwed-in condition ensures increased tightness. Examples of screw-in crowns can be found, among other things Swiss Patents No. 468 663, 582 908, 616 809, or German Patents No. 30 17 496 and 33 13 515, or take from the publication mentioned at the beginning.
  • the task is for a wristwatch of the type mentioned Art solved in that signal means are provided which are in active connection with the crown and signal whether the crown is screwed in, or Not.
  • the essence of the invention is thus the wristwatch train that the carrier by suitable signaling means attention is drawn to this when the screw-in crown is not in the properly screwed-in state.
  • acoustic within the scope of the invention
  • signaling means for example one electrically operated buzzer through a connected to the crown to actuate electrical contact.
  • Such training would opt for an electrical or electronic Offer a watch, but less for a watch with a mechanical one Clockwork.
  • optical display means are therefore provided as signaling means.
  • signaling means an electrical variant in the form of a Flashing light or the like is conceivable, there are optical signaling means a variety of purely mechanical implementation options.
  • One of these ways is under to arrange a crown in a signal color for the crown, which at screwed-in crown covered, with screwed-out crown but is openly visible.
  • the crown is usually on the side is arranged on the watch case, the signal effect is a limited such arrangement.
  • optical display means are arranged within the housing, and that in particular the watch has a dial and the optical display means are arranged within the dial. Since that The clock face is in a visually favorable position strong signal effect is achieved.
  • the optical Display means are designed as mechanical means and operated mechanically by the crown, the optical display means comprising a slide, which is slidably mounted below the dial is that when screwing in or unscrewing the crown between is moved two positions, and being in the dial an opening is provided which is in the displacement path of the slide and through which the respective position the slide is recognizable.
  • the slide can be made very flat and between Clockwork and dial are arranged so that one insert possible for a wide variety of movements and clocks is.
  • Can be used as an opening for the position indicator of the slide preferably use the opening of the date display, provided the watch has a separate date display.
  • Fig. 1 is a preferred embodiment in section reproduced for a wristwatch according to the invention.
  • Fig. 1a shows in the detail the part of the watch, which is the crown 20, the shaft 7 connected to the crown and its implementation covered by the case 2 of the watch.
  • 1b represents one Section in the plane A-A of Fig. 1a.
  • the wristwatch 1 of the exemplary embodiment from FIG. 1 comprises an internal movement 13 with an overlying dial 19, a housing 4 surrounding the clockwork 13 in a ring shape, a bottom 10 which closes the bottom 4, and one the housing 4 above closing bezel 2, which also the surrounds glass cover, not shown.
  • Bottom 10 and bezel 2 are in the housing 4 by means of corresponding threads screwed in, the desired tightness through seals 3 and 9 is achieved in corresponding grooves arranged in a ring between the housing 4 and the bezel 2 or base 10 are.
  • the clockwork 13 can be operated by means of a crown 20 (e.g. open or adjust), which are arranged on the outside of the housing 4 is and via a shaft 7 in not shown Way with the clockwork 13 is operatively connected.
  • shaft 7 is through a bore 8 in the housing 4 to the inside guided.
  • the crown 20, which is only partially shown in Fig. 1a is, in a manner known per se, as a screw-in crown executed, i.e. it is sealed with the housing 4 or screwed to a threaded connector attached to the housing if it is not needed and unscrewed when the clockwork to be operated.
  • the screw connection can, for example be designed as in the figures of the beginning mentioned document CH-A3-682 968 is shown.
  • the one for the The screw connection required thread goes into one Tube 5 over, which is screwed into the bore 8 in the housing 4, pressed or otherwise firmly inserted and surrounds the shaft 7 concentrically.
  • the tube 5 is screwed when shown in FIG. 1 Embodiment extended to the inside and protrudes the inner surface of the housing 4 into the interior of the Clock in.
  • a Tooth segment 11 rotatably mounted, which preferably the in Fig. 1b has the shape shown.
  • the tooth segment 11 is designed as a circular ring.
  • the inner diameter of the annulus is chosen so large that the shaft 7 without difficulty through the inner opening of the tooth segment 11 can be led to the clockwork 13.
  • a circumferential annulus segment 15 integrally formed, which has a segment angle of preferably has about 240 °.
  • the one from the circular ring segment 15 An angle of 120 ° which is not detected forms an engagement area for a driver finger 14, the function below is described in more detail.
  • On the outside of the tooth segment 11 is a plurality of teeth 16 in the circumferential direction arranged one behind the other when rotating the tooth segment around the tube axis in succession in corresponding engagement openings 18 engage in an overlying slide 17 and the slider in a plane parallel to the dial 19 move (see Fig. 2a, b).
  • the slider 17 can - as shown in Fig. 2 - the shape a circular ring segment, which when rotating the toothed segment 11 accordingly by a certain angle
  • the pointer axis of the wristwatch 1 is rotated.
  • the slide 17 is arranged directly below the dial 19.
  • the dial 19 is in the displacement path of the slide 17 an opening 21 is provided.
  • the opening 21 can in principle especially for the display of the screwing in of the Crown may be provided. However, the opening is preferred a date display 22 used, provided that this in the wristwatch is present (Fig. 2b).
  • the slider can now - depending on the screwed-in state of the crown 20 - take two extreme positions: in one extreme position, which corresponds to a screwed-out crown 20, (Fig. 2a), the slide 17 closes the opening 21. Is the top of the slider 17 in this area a striking, contrasting to the color of the dial 19 Color (e.g. red on a white dial), the closed opening 21 appears red Dot inside the white dial.
  • the carrier of the This effectively draws attention to the wristwatch made that the crown has not yet been screwed in and the Watch is at risk.
  • the crown 20 is complete screwed in, the slide 17 takes a second extreme position a (Fig. 2b), in which he releases the opening. In The opening is then shown the date in the usual way.
  • the length of the crown tube 6 is chosen so that it is inside with the crown fully screwed in at about the same height ends like the tube 5. There is 6 at this end of the crown tube the driver finger 14 already formed above. At appropriate choice of the pitch of the thread on the threaded connector the crown can now be reached when screwing in the crown 20, the crown tube 6 with the driver finger 14 can rotate freely in a screw-like movement, the driver finger 14 increasingly inside the watch wanders until it reaches the inner opening of the Tooth segment 11 dips and engages with the ring segment 15 is coming. The driver finger 14 then rotates the tooth segment 11 and the slider 17 are the opening 21 in the dial 19 free. An automatic rotation of the toothed segment 11 is thereby prevented that on the outside of the Clockwork 13 a spring 12 is attached to the toothed segment 11 presses against the tube 5 and so for the necessary friction worries.
  • the invention is not based on that embodiment explained here is limited.
  • the coupling between the crown 20 and the display means 17, 21 differently be formed and for example by special levers or joints.
  • the display means themselves can also be used in many variations. So it is under other possible to design the dial so that at unscrewed crown the digits of the hour disappear and only when the crown is fully screwed in are visible. It is also conceivable for the display to be controlled electrically by means of a contact and as a display to use electro-optical or electro-acoustic means. Overall, the invention results in an effective one Means to prevent unwanted interference with a screw-in watch due to environmental influences with a comparatively large To avoid security.
