    The invention relates to a Repetieruhr with a barrel from which both a clockwork and a percussion driven, with a Federhausrad of the barrel, the rotatably driven by a winding crown on an elevator train with an engageable in the spring wheel first crown wheel and by rotary drive of the spring wheel in the elevator direction a tension spring of the barrel is tensioned and engages in a Schlagwerkantriebsrad a percussion, with a manually movable from a non-triggering position triggering element, the percussion mechanism can be triggered by movement of the trigger element from the non-triggering position to the release position
    In such a repeating clock, the winding crown rotates counter to the direction of rotation of the triggered striking mechanism. It can happen that thread-like material or hair on the arm of the wearer of the clock on the winding crown or the winding shaft wind up and thereby can lead to damage or pain of the wearer of Repetieruhr.
    From US 2008/0 144 448 A1 a Repetieruhr with a barrel is known, of which both a clockwork and a striking mechanism are driven. The barrel can be tensioned by a winding crown via an elevator wheel train. If the percussion mechanism is driven, the elevator wheel train is decoupled from the elevator crown by axial displacement of the elevator crown.
    The object of the invention is therefore to provide a Repetieruhr of the aforementioned type, which avoids winding a thread-like material or hair on the arm of the wearer of the clock on the winding crown or the elevator shaft with a simple structure.
    This object is achieved according to the invention that the winding crown can be decoupled by the movement of the trigger element from the non-triggering position in the release position of the Federhausrad, wherein the first crown wheel by the movement of the trigger element from the non-triggering position to the release position out of engagement of the Federhausrad can be brought.
    By this training, it does not come to a turning of the winding crown and the elevator shaft during the expiry of the triggered impact mechanism, so that it does not come to a winding thread-like material or hair on the arm of the wearer of the clock on the winding crown or the elevator shaft and This can cause damage or pain. Also, during the running of the percussion mechanism, no influence can be caused on the percussion mechanism via the winding crown and damage caused thereby.
    When decoupling the winding crown, not only the winding crown but the entire elevator wheel train following the first crown wheel is decoupled and leads to no energy losses due to friction.
    The energy of the barrel is largely unaffected by the elevator train for the percussion available.
    At the same time, however, the required space of the Repetieruhr can be kept low because not two separate barrels but only a single barrel is needed for both functions for the drive of clockwork and percussion.
    Requiring little space, the triggering element can be a pivotable between the non-triggering position and the release position about a trigger pivot axis two-armed release rocker, through the first arm the striking mechanism can be triggered and the elevator crown of the Federhausrad can be decoupled by the second arm.
    In a simple, small space-requiring training while the first crown wheel can be rotatably mounted on a pivotable about a rotational axis of the spring wheel Wippenschwenkachse Kronradwippe about a first Kronradachse, wherein the Kronradwippe of the second arm of the release rocker between an engagement position of the first crown wheel in the Federhausrad and a disengaged position of the first crown wheel in the spring wheel to the rocker pivot axis is driven in a pivotable manner.
    If a second crown wheel of the winding crown leading to the elevator crown is rotatably mounted about a second crown wheel axis coaxial with the rocker pivot axis, which engages in the first crown wheel, the first crown wheel also continues to be present even when the first crown wheel is uncoupled from the spring wheel coupled to the elevator wheel train. A later re-engagement of the first crown wheel is thus required only on the spring wheel, so that no synchronization of engagement of the first crown wheel in the Federhausrad and the elevator wheel train is required.
    A simple movement drive for pivoting the Kronradwippe is that in the end of the second arm of the release rocker a slot is formed, which extends tangentially to the spring wheel and transverse to the pivoting movement of the second arm, with one on the Kronradwippe at a distance to the first crown wheel arranged driving pin extends into the slot, wherein the driving pin between the first crown wheel axis and the second crown wheel axis can be arranged on the crown gear.
    The slot can be fork-shaped at one end open.
    To reduce friction losses can be rotatably mounted on the driving pin a driver roller.
    In order to avoid that when the trigger element from the release position in the non-triggering division expires before the end of the percussion mechanism the torque available to the percussion break through the co-rotation of the elevator train and can be exercised on the elevator crown influence on the striking mechanism, the Winding crown during the course of the percussion of a holding device of the Federhausrad be decoupled durable.
    For this purpose, the release rocker of the holding device in the release position can be preserved in a simple manner. In a simple and small space-requiring training to the holding device may have a pivotable on the release rocker about a holding axis fall lever which is spring-loaded in the release position of the release rocker in a blocking stop behind engaging blocking position, in which he pivoting the release rocker from the release position in the non-triggering blocked.
    A deblocking is possible in a simple manner by the arrival lever of a return lever of the percussion from the blocking stop behind engaging blocking position in a blocking stop not engaging behind Entblockierstellung is movable.
    As a result, a rebound of the impact lever is automatically effected by the percussion after his stroke program.
    Engages a Schlagwerkantriebsrad in the Federhausrad, through which the Schlagwerkantriebsstrang the hammer mechanism is driven, between the Schlagwerkantriebsrad and the Schlagwerksantriebsstrang a freewheel, is arranged, by which the rotation of the spring wheel in the direction of rotation of the Federhausrads on the percussion drive train is nontransferable, so can not be driven when tensioning the tension spring of the barrel over the spring wheel and the percussion. An embodiment of the invention is illustrated in the drawing and will be described in more detail below.

    The figures show a can-like barrel 1, at the lower end of an external toothing 2 is arranged, via which a clock mechanism is driven.
    In the barrel 1 coaxially a spring core 3 is rotatably mounted, which is enclosed by a not shown spiral-type tension spring, which is fixed with its outer end to the wall of the barrel 1 and with its inner end to the spring core 3.
    At the protruding from the barrel 1 upper end of the spring core 3, a Federhausrad 4 is coaxially fixed, in which a first crown wheel 5 of an elevator crown, not shown, the Repetieruhr leading elevator train is engageable.
    Elsewhere, a percussion drive wheel 6 engages the spring wheel 4.
    The first crown wheel 5 is rotatably mounted on a crown wheel rocker 7 about a first crown wheel axis 8, which extends parallel to the axis of rotation of the spring wheel 4 and thus of the spring core 3.
    On the crown gear 7 a engaging in the first crown wheel 5 second crown wheel 9 of the elevator train is rotatably mounted about a second crown wheel axis 10, wherein the entire crown gear rocker 7 is rotatably mounted about a rocker pivot axis 20 which extends coaxially to the second crown wheel axis 10.
    The crown wheel rocker 7 is pivotable between an engagement position of the first crown wheel 5 in the spring wheel 4 and a disengaged position of the first crown wheel 5 in the spring wheel 4.
    In the engaged position of the first crown wheel 5 in the spring wheel 4, the tension spring of the barrel 1 of the winding crown on the elevator gear train and the second crown wheel 9 and the first crown wheel 5 can be tensioned.
    The pivot drive of the crown wheel rocker 7 is formed by a pivotable about a parallel to the spring core 3 outside the spring barrel 1 Auslöseschwenkachse 12 tripping rocker 11 formed the two-armed and manually against the force of a spring 13 from a non-triggering position (Fig 2) in a release position (Fig. 3 and 4) is pivotable.
    The release rocker 11 has at the end of its second arm 14 a fork-like slot 15 which extends approximately tangentially to the spring wheel 4 and in which a rotatably mounted on a driving pin 16 Mitnehmerrolle 17 projects, wherein the driving pin 16 between the first Crown wheel 5 and the second crown wheel 9 is arranged parallel to the spring core 3 on the crown wheel rocker 7.
    At the free end of the first arm 18 of the release rocker 11, a tower pawl 19 is arranged, which engages in the tower wheel 28. By pivoting the release rocker 11 from the non-triggering position in the release position, the first crown wheel 5 is coupled out of the Federhausrad 4 and on the other twisted the tower pawl 19 the Schlagwerksantriebsrad 6, whereby the striking mechanism is triggered.
    The tower pulley 28 is further provided with a freewheel 21 through which the rotation of the Schlagwerksantriebsrads 6 is not transmitted to the following, leading to the striking mechanism, not shown Schlagwerkantriebsstrang upon rotation of the spring wheel 4 in the lift direction.
    As shown in FIGS. 5 to 8 is arranged on the release rocker 11 a pivotable about a holding axis 22 Einfallhebel 23 which engages in the non-triggering position of the release rocker 11 a rest stop 24 on a board 25 of the Repetieruhr (Fig. 5).
    Is to trigger the percussion the release rocker 11 is pivoted from the non-triggering position to the release position, the engagement lever 23 is disengaged from the rest stop 24 (FIG. 6) and is by a spring, not shown in a blocking stop 26 on the board 25th behind engaged blocking position (Fig. 7) pivoted. In this blocking position, the release rocker 11 is blocked in its release position and can not swing back to the non-release position.
    When the striking mechanism has run completely, a reset lever 27 is moved against the incident lever 23 (FIG. 8) and pivots it into its unlocking position (FIG. 5), so that the release rocker 11 also returns to its position from the spring 13 Non-release position can be moved while the first crown wheel 5 again comes into engagement with the spring wheel 4.
