    专利说明:

    The invention relates to a clock with a arranged in a barrel tension spring through which a clock and a striking mechanism are driven, with a pusher member which is manually movable from a rest position to an actuating position, wherein in the operating position of the pusher element Schlagwerk is triggered.
    In such a clock, the energy consumption of the percussion is relatively high, so that it can happen that the residual power reserve of the mainspring after actuation of the percussion only sufficient to drive the oscillating system of the clock for a short time or even no longer drive.
    The object of the invention is therefore to provide a clock of the type mentioned, in which after an actuation of the trigger element of the percussion always at least a certain Mindestgangreserve the tension spring remains.
    This object is achieved in that falls below a certain minimum reserve capacity of the tension spring of the barrel, the pusher element is decoupled from the percussion.
    This training occurs after an actuation of the trigger element either to trigger the percussion, after its expiration at least the minimum transition reserve is available, which ensures continued operation of the oscillating system of the clock for a period of at least several hours, or it comes in Trap lower power reserve than the minimum gear reserve to trigger the percussion.
    So it can not happen that immediately after the triggering and expiration of the percussion stop the clock.
    Furthermore, it is avoided that the power reserve is too low to drain the triggered percussion completely, so that a wrong value is struck.
    The clock is preferably a Repetieruhr, in which the ailing value is the time.
    The specific minimum reserve power, which can be 12 hours, is preferably higher than the power reserve required for a complete drive of the striking mechanism.
    In a simple and little space-requiring training, the pusher element can be a lever handle pivotable about a pusher lever, which is coupled by means of a coupling device with a pivotable about the trigger lever axis coaxial or parallel trigger lever release rocker, through which the striking mechanism can be triggered.
    By disengaging the trigger lever of the release rocker, the release rocker can not be pivoted from the trigger lever and trigger the percussion.
    In a simple embodiment, a coupling and uncoupling of the trigger lever of the release rocker is possible because the release pin of a pivotable about a locking lever axis between a locking position and an unlocking position driven locking lever engaged behind and from its dome position in its Entkuppelstellung is movable, preferably the Trigger pin against a spring force from its coupling position is moved into its Entkuppelstellung to be moved back into its dome position can.
    In this case, the release pin of a pivotable about a locking lever axis between a locking position and an unlocking position driven locking lever can be engaged behind and movable from its coupling position into its Entkuppelstellung.
    To drive the locking lever, the locking lever can be driven in a simple manner by a pivotable about the locking lever axis stop lever pivotally driven in turn by a lifting drive is driven.
    A small space is required when the lifting drive has a Abschaltkurvenscheibe at which the stop lever is in contact and whose radially revolving stroke curve has a first region of larger diameter and a second region of smaller diameter and with a maximum of one revolution per complete power reserve about a Abschaltkurvenachse is rotatably driven, wherein the release lever of the full lift of the barrel to reach the minimum reserve reserve of the barrel at the first region of the lift curve and after reaching the minimum reserve reserve until the end of the power reserve of the spring of the barrel at the second region of the lift curve slides.
    For rotational drive of the Abschaltkurvenscheibe can be rotatably driven about the Abschaltkurvenachse in a simple design and small space-requiring manner parallel to Abschaltkurvenscheibe Abschaltrad with a maximum of one revolution per full power reserve and form the transition from the first region to the second region of the lift curve a ramp wherein the Abschaltrad is coupled to the Abschaltkurvenscheibe over a Lose to which the Abschaltkurvenscheibe on the sliding of the Abschaltungshebels on the ramp by the release lever by a certain pivot angle relative to the Abschaltrad is advanced. This override results in a quick uncoupling of the trigger lever of the release rocker.
    In a simple way, the overfeed is thereby effected in that the Abschaltrad has a extending in the circumferential direction slot in which a driving pin of Abschaltkurvenscheibe protrudes.
    An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it<Tb> FIG. 1 <SEP> a view of a Schlagwerkabschaltungseinrichtung with a release rocker in the actuatable position of the percussion<Tb> FIG. 2 <SEP> the Schlagwerkabschaltungseinrichtung of FIG. 1 with the release rocker in non-actuated position of the impact mechanism.
    The Schlagwerkabschaltungseinrichtung shown a repeater with a rear derailleur has a shut-off 1, which is rotatably driven by a turn-off spring of a barrel with a rotation of 213.6 ° per complete power reserve of the barrel counterclockwise about a Abschaltkurvenachse 2. Since also the clockwork of the clock is driven by the tension spring, the cut-off wheel 1 rotates continuously, although the movement is running. When the watch is wound up, the cut-off wheel turns clockwise.
    Parallel to Abschaltrad 1 is also a Abschaltkurvenscheibe 3 rotatably mounted about the Abschaltkurvenachse 2, which has a extending in the direction of rotation by 13 ° slot 4, into which a driving pin 5 of the shut-off wheel 1 protrudes.
    The turn-off cam 3 has a radially encircling lift curve 10, which has a first region 8 of larger diameter and a second region 9 of smaller diameter. The second region 9 of smaller diameter corresponds in its length to a circulating movement of about 12 hours, which corresponds to the Mindestgangreserve the tension spring.
    At the transitions from the first region 8 to the second region 9 of the lifting cam 10, a first ramp 20 and a second ramp 21 are formed.
    At the lift curve 10 a two-armed release lever 11 is held with the free end of its first arm 12 by a second spring 13 in abutment. The release lever 11 is pivotally mounted about a locking lever axis 14.
    At the free end of the second arm 15 of the Abschaltungshebels 11 a driving cam 16 is arranged, which is on a first lever 18 of a two-lever, also about the locking lever axis 14 pivotally mounted locking lever 17 in abutment and this against the force of a third spring 19th counteracted in the counterclockwise direction. The locking lever 17 is pivotable between a locking position and an unlocked position.
    At the free end of the second lever 22 of the locking lever 17, a hook 23 is arranged, which is in its unlocked position disengaged from a release pin 24. By pivoting the locking lever 17 from its unlocked position into its blocking position, the hook 23 engages behind the release pin 24 and moves it against a spring force from its coupling position into its uncoupling position.
    The release pin 24 is movably disposed in a longitudinal groove 25 at a free end of a handle lever pivot axis 27 pivotable lever 26 between the closer the lever lever axis 27 closer coupling position and the handle lever axis 27 more remote Entkuppelstellung.
    An approximately corresponding to the trigger lever 26 and parallel to the trigger lever 26 extending release rocker 28 is pivotable about a trigger lever axis 29, wherein a first rocker arm 30 of the release rocker 28 extends to half of the extension of the longitudinal groove 25 of the trigger lever 26. From a second rocker arm 31 of the release rocker 28, a clock mechanism, not shown, of the clock can be triggered.
    The trigger lever 26 is pivotable by manual transverse loading against the force of a fourth spring 33 of its longitudinal groove 25 opposite end 32 in the clockwise direction.
    If the current power reserve of the mainspring spring of the barrel larger than the Mindestgangreserve, so is the stop lever 11 with the free end of its first arm 12 in contact with the first area 8 larger diameter of Abschaltkurvenscheibe 3. The voltage applied to the driving cam first lever 18 of the locking lever 17 is pivoted so far clockwise with the second arm 15 of the Abschaltungshebels 11 that the arranged on the second lever 22 of the locking lever 17 hook 23 is disengaged from the trigger pin 24.
    This trigger pin 24 is thus due to its spring load on the handle lever axis 27 closer end of the longitudinal groove 25th
    If now the trigger lever 26 is pivoted by manual application against the force of the fourth spring in a clockwise direction, the release rocker 28 is taken over the trigger pin 24 and mitverschwenkt because the trigger pin 24 couples the trigger lever 26 in this position with the release rocker 28. With the second rocker arm 31 of the release rocker 28 thereby the striking mechanism is triggered.
    As the stop lever 11 continues to move with the free end of its first arm 12 towards the first ramp 20, it slides along the first ramp 20 from the first area 8 to the second area 9 of the lift cam 10. This turns off the turn-off cam 3 leading to Abschaltrad 1 moves, the driving pin 5 comes to rest on the rear in the direction of rotation of the cut-off wheel 1 end of the slot 4.
    It also pivot the release lever 11 and with him the locking lever 17 counterclockwise, whereby the hook 23 engages the release pin 24 and moves from its dome position to its Entkuppelstellung in which he is no longer close to the first rocker arm 30 of the release rocker 28th located.
    Thus, the release rocker 28 is decoupled from the trigger lever 26.
    Now, if the trigger lever 26 is acted upon manually against the force of the fourth spring 33, although pivoted the trigger lever 26. Due to its decoupling from the trigger lever 26 but the release rocker 28 remains unschwenkt and can not trigger the striking mechanism.
    Only by mounting the tension spring of the barrel of the first arm 12 of the Abschaltungshebels 11 back to the first area 8 of the lifting cam 10 and pivoted with his second arm 15 via the driving cam 16, the locking lever 17, so that the hook 23 again from the Trigger pin 24 pivots away and this can move to the closer the lever lever axis 27 closer end of the longitudinal groove 25, in which it again couples the trigger lever 26 with the release rocker 28.
    A manual action on the trigger lever 26 now leads again to a triggering of the striking mechanism.
