Definitions

  • the invention relates to a tension spring device of a repeater clock for driving a striking mechanism, with an elevator drive gear which is arranged in a rotationally fixed manner on a spring core axis and which can be rotatably driven by a manually pivotable elevator lift provided with a toothed segment, with a spiral tension spring which can be set with its pretension one end is attached to the spring core axis and the other end is attached to a barrel enclosing the spring core axis at a distance radially, with a striking mechanism drive arranged on the spring core axis, by means of which the striking mechanism can be driven.
  • the tension spring is also prestressed in the non-opened position.
  • a tension spring device of the type mentioned is known from CH-A 6339.
  • the barrel is fixed on a board and the spring core axis can be adjusted in 45 ° steps to adjust the tension of the tension spring.
  • a refinement of the preload setting by reducing the adjustment steps is not possible due to the small radial extent of the spring core axis.
  • a repeater watch which has a spiral tension spring, the inner end of which is fastened to a spring core axis and the outer end of which is fastened to a spring housing enclosing the tension spring.
  • the spring housing In order to tension the tension spring for a repetition process, the spring housing can be turned.
  • the object of the invention is to provide a tension spring device of the type mentioned at the outset, which enables an exact fine adjustment of the pretension of the tension spring.
  • the barrel is rotatably adjustable by means of an adjusting device about the innerspring axis in a plurality of non-rotatable positions.
  • This design enables the tension of the tension spring to be set only when the entire impact and elevator device is completely assembled. Influences due to manufacturing and assembly tolerances can thus be fully compensated and the tension spring can be provided with an optimal preload, which ensures largely the same power output over the entire working range of the tension spring. This leads to an even rhythm of the tones generated by the striking mechanism.
  • the tension spring can e.g. Repair purposes can be relaxed again.
  • the fine adjustment of the tension of the tension spring according to the invention is also possible.
  • the barrel can be blocked by means of a locking device which can be positively connected to the barrel, for which purpose the barrel can have a radially circumferential ring gear in a simple configuration, into which a preload pinion which can be driven manually rotates engages.
  • a locking device which can be positively connected to the barrel
  • the barrel can have a radially circumferential ring gear in a simple configuration, into which a preload pinion which can be driven manually rotates engages. This enables the tension of the tension spring to be adjusted continuously.
  • the preload pinion can be arranged in a rotationally fixed manner on a rotatably mounted adjusting pin which can be rotated manually.
  • the adjusting pin has on one end face a recess into which a tool can be positively inserted for manual drive, the pre-tensioning of the tension spring can be set in a simple manner. This is particularly easy if the recess is a slot for a screwdriver.
  • the blocking device can be pivoted about a pivot axis ...
  • an elevator lever 3 which can be pivoted about an axis 2, is mounted on a circuit board 1 and can be pivoted by actuating its actuating cam 4 by a path dependent on the currently displayed time of the watch.
  • This path is determined by an hourly scale 5, which is rotatably driven by the clockwork and gradually increases in diameter, against which a pin 6 of the elevator lever 3 comes to rest and limits the swivel path.
  • the elevator lever 3 has, concentrically to the axis, a toothed segment 7 which engages in an elevator drive gear 8 which is arranged on a spring core axis 9 in a rotationally fixed manner.
  • the spring core axis 9 is rotatably mounted on the board 1.
  • a spiral tension spring 10 enclosing the spring core axis 9 is fastened to the spring core axis 9.
  • the other free end of the tension spring 10 is fixedly arranged on an annular spring barrel 11, which is freely rotatably mounted on the spring core axis 9 at a distance and radially encloses the spring core axis 9.
  • the barrel 11 is designed as a ring gear 12 on its radially circumferential cylindrical outer surface.
  • This biasing pinion 13, shown enlarged in FIGS. 3 and 4 has an adjusting pin 14, on the upper end face of which a slot 15 is formed, into which a screwdriver can be inserted and the biasing pinion can be rotated.
  • a pretensioning pawl 17 is pivotally mounted on the circuit board 1 about a pivot axis 16.
  • the biasing pawl 17 is designed as a two-armed lever, one free end of which has a toothed segment 18 which engages in the biasing pinion 13 in the blocking position shown. In this blocking position, the other free end rests against a stop 19 which is fixedly connected to the circuit board 1 and which prevents the pretensioning pawl 17 from pivoting further in the clockwise direction. against this stop 19, the biasing pawl 17 is acted upon by the free end of a spring arm 20, the other free end of which is attached to the circuit board 1.
  • the pretensioning pawl 17 prevents the pretensioning pinion 13 and thus the barrel 11 from rotating in the relaxing direction of the tension spring 10.
  • the pretensioning pawl 17 has a recess 21 into which a tool can be inserted.
  • the preload pinion 13 is rotated clockwise by means of a screwdriver engaging in a slot 15. This leads to the spring housing 11 being rotated counterclockwise relative to the spring core axis 9 and thus to tensioning the tension spring 10.
  • the biasing pawl 17 pivots counterclockwise and comes out of engagement with the toothed segment 18 from the biasing pinion 13.
  • the pretensioning pawl 17 comes back into engagement with the pretensioning pinion 13 by slightly turning back the pretensioning pinion 13 and, after contact with the stop 19, blocks further relaxation of the tension spring 10 now having the desired pretension.
  • the biasing pinion 13 is rotated clockwise by means of a screwdriver engaging in the slot 15 until the biasing pawl 17 is out of engagement with the biasing pinion.
  • an hourly rake 22 shown offset, from whose teeth a scoop 23 can be pivoted.
  • the latter pivots a pivotable hourly lever 24 against the force of a spring 26 and, after jumping over a tooth of the student rake 22, causes the hour hammer to strike a sound spring 27 and produce a tone.
