  • the present invention relates to a constant force device for watches, especially for wristwatches, with a mechanism for an indirect Second.
  • the aim of the present invention is therefore to overcome the disadvantages mentioned to avoid the current systems and a constant force device for To make available, because of their conception in a simple way Anchor escapement of a new and especially an existing watch can be integrated, this to minimize the space required for the Device and its technical optimization taking into account and Utilization of the elements present in the clockwork should take place.
  • the present invention therefore has a constant force device for Watches, especially wristwatches, with a mechanism for one indirect second as an object, which those mentioned in claim 1 Has characteristics.
  • a constant force device characterized by these features can especially because of their conception in a simple way Anchor escapement of new and especially of existing watches, which one Mechanism for an indirect second to be integrated.
  • Anchor escapement of new and especially of existing watches which one Mechanism for an indirect second to be integrated.
  • this integration takes place in such a way that no or only minor changes in the existing clockwork or in the immediate vicinity of the escapement Need to become.
  • the favorable arrangement of the components of the Constant force device according to the present invention regulating the Vibration amplitude of the balance during assembly of the watch or in Post-sale service made easier.
  • the attached figures exemplify two embodiments a constant force device according to the present invention.
  • Figure 1a shows a top view of a first one Embodiment of an integrated in a clockwork with indirect seconds Constant force device according to the present invention.
  • Figure 1b is a detailed view of the device of Figure 1a to explain the interaction of individual components of the Constant-force device.
  • Figure 1c is a section along line A-A according to Figure 1a.
  • Figure 2a shows a top view of a second one Embodiment of an integrated in a clockwork with indirect seconds Constant force device according to the present invention.
  • Figure 2b is a detailed view of the device of Figure 2a to explain the interaction of individual components of the Constant-force device.
  • Figure 2c is a section along line B-B according to Figure 2a.
  • Figure 2d is a section along the line C-C according to Figure 2b.
  • Figure 1a is a top view of a clockwork showing a first, exemplary embodiment of a constant force device according to the present invention, the inhibition, seconds and Stop organs and in particular the advantageous arrangement of the components of the Constant force device are illustrated.
  • the others, not in the description or components of the clockwork or the components contained in the illustrations Gear trains are conventional and will therefore not be explained further.
  • a conventional one Tension arm drive 4, a tension arm 5, a spiral block 6, one Spiral spring roller 7 and a spiral spring 8 existing clamping module Constant force device advantageously attached to the escape wheel shaft 3 can be.
  • the tension arm drive 4 is in this case, for example, by means of two stones 4a and 4b made of ruby, rotatable about the escape wheel shaft 3 on this attached that this tension arm drive 4 with the seconds wheel 9 in engagement stands.
  • the tension arm 5 attached to the tension arm drive 4 carries this Spiral blocks 6, on which the outer end of the coil spring 8 is attached.
  • the spiral spring roller 7 is preferably on the bridge to the clockwork aligned side on the escape wheel shaft 3 attached to the coil spring roller 7 easily accessible to place and thus easier regulation of Vibration amplitude of the balance without disassembling the gear train allow.
  • FIG. 1b which shows the cooperation of Main components of the constant force device illustrated, can be seen, plays this cam 2 with a fork of an armature 11 of the constant force device together.
  • This anchor 11 can, as shown in Figure 1c, in advantageously rotatable on the seconds wheel drive 10 of the seconds wheel 9 be attached, for example by means of a ball bearing 12.
  • the anchor pallets in turn work, see Figure 1b, in conventionally with a stop wheel 13 of the constant force device together.
  • this stop wheel 13 can preferably be used for one not concentric to the escape wheel 1 and the other in particular, analogously for the unconventional arrangement of the armature 11 on the second wheel drive 10, to be attached to the second intermediate drive 14 mentioned above.
  • the non-concentric arrangement of the stop wheel 13 to the escape wheel 1 allows the choice of different gear ratios between the Arm arm 4 and the second wheel 9 on the one hand and the Second wheel 9 and the stop wheel drive, which in the present example with the Secondary drive 14 is identical, on the other hand.
  • the Rotation speed of the stop wheel 13 by reducing it Moment of inertia can be optimized.
  • the existing one Axis of rotation of the intermediate intermediate drive 14 also serves as the axis of rotation for the Stop wheel 13 used.
  • this is located above the second intermediate drive 14 engages with the seconds wheel 9, and by avoiding an additional one
  • the axis of rotation thus saves space and simplifies integration achieved by the constant force device in the clockwork.
  • the stop wheel 13 is thereby under the influence of Torque of the second wheel 9 and is on one of the pallets of the armature 11th the constant force device pressed.
  • the resulting reduction in axial play of the stop wheel 13 considerably reduces the play of the indirect second wheel 15. Therefore, with this arrangement of the stop wheel 13 the generally on the indirect seconds wheel 15 to avoid the consequences thereof Play built-in friction spring are eliminated, which increases performance translation operation and simplification of the clockwork is effected.
  • Second intermediate drive 14 Due to the special arrangement of the stop wheel 13 on the one hand Second intermediate drive 14 and the other of the armature 11, coaxial to Second wheel 9, on the second wheel drive 10, the integration of a Constant force device in a clockwork with a mechanism for indirect Second optimized, especially what the efficient use of space, the usage existing elements of the clockwork for purposes of constant force device and the simplification of the clockwork involved.
  • the escape wheel 1 rotates one certain angle, in the present example by 9 °, about its axis of rotation out. With a given number of half vibrations the balance, here at the fourth, i.e. when the escape wheel 1 rotates by 36 ° about its axis has performed, the escape wheel 1 over the attached to the escape wheel shaft 3 Cam 2 and on the second gear 10 by means of the ball bearing 12 rotatably attached armature 11 of the constant force device, the stop wheel 13 freely.
  • the stop wheel drives 13 via the stop wheel drive, that means here the second intermediate drive 14, the Second wheel 9 and the indirect second wheel 15, which is, for example, in the Center of the ad can be located at.
  • the second wheel 9 in the case of a regulator with a frequency of 4 Hz jump out every half second.
  • the seconds wheel 9 drives via the tension arm drive 4 rotatably mounted on the escape wheel shaft 3 attached to this tension arm 5 and thus ensures the Retensioning the spiral spring 8 of the constant force device.
  • the number of teeth of the escape wheel shaft 3 and the stop wheel drive, that is here the second intermediate drive 14 is selected such that the tension angle the spiral spring 8 is identical to the angle of rotation of the escape wheel 1, in the example 36 °, during the specified number of half-oscillations, here four.
  • the angular amounts given are only exemplary and can also be chosen otherwise.
  • the above-mentioned frequency of the regulator or that for the present example from the figures apparent number of teeth of the different wheels and the number of sides of the cam 2 are not specified and can also be chosen elsewhere.
  • the frequency chosen by the regulator is usually a practical one Configuration for the number of teeth of the different wheels as well as the number the sides of the cam 2 interesting and is used.
  • FIG. 2a A second embodiment of a constant force device according to the present invention is illustrated in Figures 2a to 2d.
