Definitions

  • the present invention relates to an adjusting device according to the preamble of claim 1.
  • Such actuators especially in the form of rotatably mounted crowns exist in a variety of embodiments. Often, such crowns have two or more axial positions in which various functions can be performed. Switching is done manually by the user of the associated clock. Examples include the ones in the documents US 6,200,020 and EP 0 556 155 described actuators, which represent ringkronen and must be manually brought by the user in the respective desired axial position. This may be undesirable or even detrimental in some applications, for example, clock applications in dives, where safety issues are involved. In this context, it should also be mentioned that the different positions of such a setting unit usually have different water tightness. Again, it is up to the user to bring the crown in the intended position with the best tightness, before he undertakes about a dive, which takes place for example, usually by screwing the crown.
  • the object of the present invention is therefore to avoid the aforementioned drawbacks and to provide an actuating unit which carries out the aforementioned operations automatically.
  • the object of the present invention is characterized by the features mentioned in the characterizing part of claim 1.
  • an adjusting device has an elastic element whose biasing force is determined by the size of the end face of the outer crown body of the device.
  • an adjusting device allows it to be automatically switched from one axial position to another depending on the applied external pressure, resulting in, for example, automatic disengagement or disengagement for non-performance or feasibility of a function.
  • the actuator can automatically switch depending on the applied external pressure in their best sealing position, which is especially in divers watches advantage.
  • FIG. 12 is a cross-sectional view of an actuator incorporated in a watch case according to the present invention, with it being in its normal position.
  • FIG. 12 is a cross-sectional view of an actuator incorporated in a watch case according to the present invention, with it being in its normal position.
  • the Figure 2 is a to illustration 1 analogous cross-section in which the adjusting device is slightly axially displaced due to a rotation made against the intended direction of rotation, in order to enable a locking of the coupling.
  • the Figure 3 is again one too illustration 1 analogous cross-section in which the adjusting device is axially displaced due to the action of the applied external pressure in order to enable a disengagement.
  • the Figure 4 is an exploded view of the most important parts of an adjusting device used to control a rotary ring together with the parts belonging to the rotary ring.
  • the Figure 5 is a perspective view of an example of a usable coupling in this context.
  • an actuating device 1 according to the present invention, a crown body 11, 12.
  • This can be made of one piece or be joined together from several, firmly interconnected items, and has an outer crown body 11, which is substantially cup-shaped, and an inner crown body 12.
  • the latter is essentially cylindrical and has a smaller outer diameter than the inner diameter of the cup-shaped part of the outer crown body 12, in which it is mounted on.
  • the crown body has an annular cavity 19 between its two parts 11, 12.
  • a coupling 13, 14 which may have different configurations depending on the purpose, attached to this.
  • a crown bushing 15 at least partially surrounds the inner crown body 12 and the coupling 13, 14, these parts being rotatably mounted in the crown bushing.
  • the crown bushing 15 is used as usual at a suitable location on the edge of the housing 2 of a clock, wherein the outwardly facing end of the substantially hollow cylindrical crown bushing 15 projects into the annular cavity 19 between outer - and inner crown body 12.
  • the adjusting device 1 also has an elastic element 16 which acts on at least one of the crown members 11, 12 in order to bias it in its axial direction.
  • the crown body 11, 12 together with parts of the coupling 13, 14 is therefore mounted both axially displaceable and rotatable within the crown bushing 15.
  • the biasing force of the elastic element 16 is determined as a function of the effective end face A of the outer crown body 11.
  • Such a design of an adjusting device makes it possible to ensure an automatic, axial position switching of the adjusting device in response to the applied external pressure.
  • the elastic element may in particular be configured as a helical spring 16, for example, between the crown bushing 15 and the inner crown body 12, a part of the coupling 13, 14 spanning mounted.
  • a spring 16 could also be mounted between the crown bushing 15 and the outer crown body 11. It is only important that in the axial direction, a bias of the crown body 11, 12 is generated relative to the fixed to the watch case 2 crown bushing 15.
  • This biasing force preferably acts as in illustration 1 shown in the direction of the housing outwardly facing direction, so as to be at normal ambient pressure, a normal position of the actuator to define. At a given, higher external pressure, the crown 11, 12 of the actuator automatically moves into an axially inwardly shifted position, as in Figure 3 is shown.
  • a reverse constellation is conceivable in which an inwardly acting biasing force is given, which causes an external displacement of the crown 11, 12 at low external pressure, the chosen constellation will depend on the desired application, as to later Place will be discussed.
  • bevel 11 a is mounted so that it does not or only slightly touches the associated sealing ring 17 a in the normal position of the actuator 1, while an automatic axial displacement of the crown 11, 12 to the contact surface 15 a of the crown bushing 15 a Compression of this sealing ring 17a and thus brings an automatic increase in the tightness of the adjusting device 1 with it.
  • sealing ring or rings 17 may be attached to the outside of the outwardly facing end of the crown bushing 15 and the bevel 11a cooperating therewith on the inside of the outer crown body 11. This is the case in the present embodiment, which is illustrated in the figures as an example case, where another Sealing ring 18 is mounted between inner crown body 12 and crown bushing 15.
  • This embodiment could be chosen otherwise, for example by the sealing rings 17 are arranged on the inside of the outer crown body 11 and the bevel 11 a on the outside of the crown bushing 15, or by one of these arrangements between inner crown body 12 and crown bushing 15 is made while another sealing ring 18 is located approximately on the outer crown body 11.
  • the automatic, axial displacement by overcoming the spring biasing force at (pre-) given external pressure in the adjusting device according to the invention can also be used in conjunction with the clutch 13, 14 in an advantageous manner.
  • the coupling 13, 14 may be designed such that it is engaged and disengaged by an axial movement of the crown body 11, 12. This is done at a (pre-) certain external pressure by the automatic, axial position switching of the actuator automatic disengagement or engagement, depending on the specific design of the clutch.
  • the reproduced in the illustrations coupling has a force applied to the inner crown body 12, approximately screwed, so-called driving screw 13 with teeth 13a at their directed into the housing interior end. It also has a between the drive screw 13 and the crown bushing 15 rotatably mounted gear 14, which has a directed to the teeth 13a of the drive screw 13 Breguetsche side toothing 14a (also called Breguetahnung or saw toothing) on.
  • the spring 16 pushes the crown 11, 12 outwards, therefore, the teeth 13a of the driving screw 13 abut on the Breguetschen side toothing 14a of the gear 14, so that the clutch 13, 14 is engaged and a rotation of the outer crown body 11 rotation of the gear 14 causes.
  • the coupling instead of a side toothing can be realized by interlocking, polygonal surfaces; other possibilities are included in the prior art.
  • the coupling can also be designed so that instead of the automatic disengagement takes place as in the present example, an automatic engagement, for which an arrangement of the side toothing 14a and the teeth 13a of the driving screw 13 at the outwardly directed end of the gear 14 would be sufficient in the example set forth.
  • FIG. 4 the adjusting device for controlling an internal, toothed rotary ring 31 is used.
  • a work ring 24 which is inserted into a watch case 2 having a housing bottom 21 (bottom) and a housing top 22 ( illustration 1 Its centering takes place by means of a Trolageringes 33, which is under a watch glass 23, while the support of the rotary ring 31 in the housing 2 by means of cover stones 32, for example made of artificially produced ruby, is realized.
  • a locking plate 25 a such as artificially made ruby
  • the inner rotary ring mechanism 3 is now controlled by the adjusting device 1, insofar as a rotational movement on the outer crown body 11 (in the intended direction of rotation) in the normal position of the device (see illustration 1 ) causes a rotation of the gear 14, which engages in the toothing 31 a of the rotary ring 31 and thus rotates.
  • a rotational movement on the outer crown body 11 in the opposite direction causes due to the blocking of the rotary ring 31 in this direction of rotation by the detent spring 25, a locking of the clutch 13, 14, as in Figure 2 shown, so that the rotary ring 31 is not moved in this case.
  • a (pre-) given, increased external pressure on the outer crown body 11 finally takes place, an automatic, axial position switching the crown (see Figure 3 ), which has an increased tightness and an automatic disengagement, so that the rotary ring 31 is not adjusted in (accidental) rotation of the outer crown body 11, the result.
  • Such an actuator is therefore particularly useful in divers watches, as in this case an unintentional adjustment of the rotary ring for the safety of the diver would be important and must be avoided.
