    The invention relates to an adjusting device of a clock, with an actuating shaft which is movable by axial movement from a normal position to a zero position, wherein the movement of the actuating shaft from the normal position to the zero position, a spring-actuated zero actuator is triggered by the a fixedly arranged on a pointer shaft pointer in the neutral position is drivingly driven, with a clutch through which the pointer shaft of the pointer is frictionally coupled to the clockwork of the clock, wherein between the pointer shaft and a gear train of the movement, a prestressed clutch spring is arranged, which Clutch loaded in Einkuppelrichtung.
    In order to perform a zero position of the pointer, without affecting the drive of the movement, in such a device for adjusting a pointer of a clock, a clutch is known, coupled by the pointer shaft of the pointer frictionally with the clockwork of the clock and decoupled to reset the pointer.
    The object of the invention is to provide a device for zeroing a pointer of a clock of the type mentioned, which allows a small zero position of the pointer with a small size.
    This object is achieved according to the invention that the clutch is a releasable positive and / or positive clutch having a coaxial to the pointer shaft first clutch disc, with which the pointer shaft is rotatably connected and having a second clutch disc and a third clutch disc which are rotatably connected to the gear train, wherein the second clutch disc and the third clutch disc coaxial with the pointer shaft to receive the first clutch disc between them and are subjected to the Kuppelfeder against the first clutch disc with a force actuated by the actuating shaft separating device, by the movement the actuating shaft from the normal position to the zero-part position, the second clutch disc and the third clutch disc from its frictionally engaged with the first clutch disc closing positions are movable into their lifted from the first clutch disc opening positions.
    The pointer is preferably a second hand and the pointer shaft a second hand wave.
    By the momentum can e.g. be a minute hand adjustable. The control shaft can also be used to wind the clock.
    With this design, the clutch is opened by zeroing the second and third clutch disc of the first clutch disc and thus solved the connection between the pointer shaft and the gear train of the clock, so that the pointer shaft are at least largely free of resistors placed in a neutral position can.
    By only a single clutch spring, which acts on both the second and on the third clutch disc in the closing direction, results in a small size.
    Furthermore, a small size results in that with the first and third clutch disc two clutch plates for closing the clutch are present, which can have a smaller diameter at high coupling forces.
    In a simple way, the second and the third clutch disc can be held by a single clutch spring in abutment with the first clutch disc, when the second clutch plate has a plurality of tie rods parallel to the pointer shaft, of the third clutch disc against the first clutch disc loading dome spring such are energized that they pull the second clutch disc in abutment with the first clutch disc.
    The dome spring can be weight saving a more radially directed spring arms having spring, wherein each radially inner Federarmende acts on the third clutch disc and wherein each radially outer Federarmende is axially supported on one of the tie rods.
    For simultaneously lifting both the second clutch disc and the third clutch disc of the first clutch disc, the separating device may comprise at least one spreading blade, which consists of one of the second clutch disc and the third clutch disc radially spaced non-separation position in between the second clutch disc and the third Clutch disc radially movable to the first clutch disc inserted separating position is movable, wherein the spreading blade in the extension direction of the pointer shaft has a thickness which is greater than the thickness of the first clutch disc.
    In order to allow a slight radial insertion of the spreading blade between the second clutch disc and the third clutch disc, the spreader blade at its first clutch disc radially facing end has a smaller thickness than the thickness of the first clutch disc, wherein the thickness of the spreader blade with radial Distance from the first clutch disc increased to a thickness greater than the thickness of the first clutch disc.
    For a uniform lifting of the first and the second clutch disc of the first clutch disc, it performs when the separator has two at least approximately diametrically opposed spreading blades, which are movable together by the actuating shaft in its separation position and its non-separation position.
    In the axial movement of the actuating shaft from the normal position in the direction of the zeroing position, an actuating lever or an actuating lever arrangement about an axis or about an axis from a rest position in a triggering position triggering the zeroing drive can be driven in a pivotable manner.
    If the spreading blade is arranged on a Spreizklingenhebel at a distance to a Spreizklingenachse, wherein the Spreizklingenhebel is pivotally mounted about the Spreizklingenachse and is pivotally driven by the actuating lever or the actuating lever assembly from a non-separation position to a separating position, the actuating lever or the actuated Operating lever assembly in components-saving manner, both the zeroing drive and the spreading of the separator.
    In a simple embodiment, the zero setting drive can have a heart lever pivotally mounted around a heart lever axis, which is driven by the axial movement of the actuating shaft from the normal position to the zero position movable, wherein the heart lever at a distance from the heart lever axis has a footprint in the normal position the control shaft is held at a radial distance to a radially encircling heart curve of a heart cam plate fixedly arranged on the pointer shaft and is in the neutral position under a spring force in contact with the heart cam.

    Fig. 3 is a plan view of the adjusting device according to Fig. 1 in the zeroing position Fig. 4 is a section along the line B-B in Fig. 1st
    Fig. 5 is a bottom view of the clutch, zeroing device and separator of the adjustment device of FIG. 1 in the normal position.
    The adjustment shown for adjusting a clock has an actuating shaft 1, which is axially movable from its normal position shown in FIG. 1 in its position shown in FIG. 3 position. The actuating shaft may have on its right end protruding from a watch case, not shown, a crown, by means of which in befindstellposition befindlicher actuating shaft, for example. a minute hand of the clock is adjustable by turning the control shaft.
    The actuating shaft 1 has an annular groove 2, in which one end of a two-armed first actuating lever 3 engages such that this actuating lever by axial movement of the actuating shaft 1 from the normal position to the adjusting position about an axis 4 from a rest position (Fig. 1) in a release position (Fig. 3) is pivotally driven.
    At the second end of the actuating lever 3, a pin 5 projecting parallel to the axis 4 is arranged, through which a first arm 6 of a two-armed heart lever 7 pivotable about a heart lever axis 8 from a zeroing position to a normal position and a second arm 9 of the heart lever. 7 from its normal position in its neutral position can be acted upon swivel. The acted upon by the pin 5 free end of the second arm 9 of the heart lever 7 is designed as a spring arm 10.
    At a distance from the heart lever axis 8 whose second arm 9 has a footprint 11 which is in the normal position of the heart lever 7 at a radial distance to a radially encircling heart cam 12 of a heart cam 13, the fixed on a second hand 15 carrying second hand wave 14 is arranged and rotatably driven about a pointer axis 47.
    If the heart lever 7 is pivoted by means of the first actuating lever 3 from its normal position (FIGS. 1 and 2) into its zero setting position (FIGS. 3 and 4), the footprint 11 reaches the heart cam 12 through the spring arm 10 spring loaded to the plant. By radial loading of the heart cam 12 by the footprint 11, the heart cam 13 is pivoted so far until the footprint 11 reaches the pointer axis 47 at the radially lowest point. Thus, the second hand 15 disposed on the second hand shaft 14 is also moved to its zero position.
    On the second hand shaft 14, a first clutch disc 16 is further fixed. A second clutch disk 17 and a third clutch disk 18, which are coaxial with the first clutch disk 16, are each arranged on one side of the first clutch disk 16.
    The second clutch disc 17 and the third clutch disc 18 have a larger diameter than the first clutch disc 16. In the radially outer circumferential region are distributed on the second clutch disc 17 evenly distributed around the circumference of two tie rods 19 which radially outside the first clutch disc over and with the least possible play protrude through openings of the third clutch disc 18 and are provided at their free ends with radially circumferentially protruding stops 24.
    A dome spring 20 encloses with its radially inner portion 21 a projecting after the first clutch disc 16 side protruding sleeve-like extension 22 of the third clutch disc 18 and has two radially outwardly directed spring arms 23, with their free ends each at one of Stops 24 are axially supported and due to the bias of the spring arms 23, the third clutch disc 18 and via the tie rods 19 and the second clutch plate 17 press against the first clutch disc 16. In this state, the three clutch discs 16, 17 and 18 non-rotatably coupled to each other non-rotatably. With the third clutch plate 18 a gear train 25 of a clock, not shown, the clock is firmly connected, so that when drehest coupled clutch plates 16, 17 and 18, a rotary drive of the first clutch plate 16 and with it the second hand shaft 14 and the second hand 15 is carried by the movement ,
    With the gear train 25 is still a sprocket 46 rotatably connected.
    The pin 5 having the end of the first actuating lever 3 engages with the pin 5 in a longitudinal opening 48 at the end of a first Betätigungshebelarms 26 pivotable about a second axis 28 two-armed second actuating lever 27, thereby characterized in pivoting the first operating lever is driven by this pivotally.
    At the free end region of a second Betätigungshebelarms 29 of the second actuating lever 27, a cam 30 is arranged with a radially encircling separation curve 31. At the separating curve 31, one end 34 of a two-armed first separating lever 33, which can be pivoted about a first separating lever axis 32, is in abutment and can be driven in a pivotable manner due to the separating curve 31 rising in the clockwise direction. At the second end of the first separating lever 33, a first spreading blade 35 is arranged. As a result of the pivoting movement of the first separating lever 33, the first spreading blade 35 can be moved in the plane of the first coupling disk 16 between a non-separating position remote from the first coupling disk 16 and a separating position closer to the first coupling disk 16.
    The spreading blade 35 has at its the first clutch disc 16 end facing a smaller thickness than the first clutch disc 16, which then with increasing distance from the first clutch disc 16 V-like to a greater thickness than the thickness of the first clutch disc sixteenth increased.
    During the movement of the spreader blade 35 from its non-separation position to its separating position, it passes between the second clutch disc 17 and the third clutch disc 18. Upon insertion of a greater thickness than the thickness of the first clutch disc 16 having portion of the spreader blade 35 between the second clutch disc 17 and the third clutch plate 18, these two clutch plates 17 and 18 lifted from the first clutch disc 16 and thus also the gear train 25 of the clock, not shown, separated from the second hand clock shaft 14, so that a zero position of the second hand 15 on the heart cam disc 13 take place unhindered can.
    In the area of the first separating lever axis 32, the first separating lever 33 has an approximately perpendicular to the separating lever 33 extending transfer lever 36, the free end of an approximately opposite takeover lever 37 of a second separating lever 38 acts with its free end.
    The second separating lever 38 is also formed with two arms and pivotable about a second separating lever axis 39.
    At the second end of the second separating lever 38, one of the first spreading blade 35 corresponding second spreading blade 40 is arranged, which is diametrically opposite the first spreading blade 35.
    Starting approximately from the area of the second separating lever axis 39, a separating lever arm 41 of the second separating lever 39 designed as a spring arm extends to the first actuating lever 3 and rests with its free end region on the pin 5. In this case, the Trennhebelarm 41 is in the non-separation position shown in Fig. 1 under a second separating lever 38 with its second spreading blade in the non-separating biasing bias. In the separation position shown in Fig. 3, the Trennhebelarm 41 without bias.
    About the transfer lever 37 and the transfer lever 36, this bias is also transmitted to the first release lever 33.
    In the normal position of the control shaft 1 shown in FIGS. 1 and 2, the first operating lever 3 and the second operating lever 27 are in their rest position. In this case, the first end 34 of the first separating lever 33 in a second axis 28 of the second actuating lever 27 closer portion of the separation curve 31 of the cam 30 abuts. This makes it possible that under the spring force of the Trennhebelarms 41 both expansion blades 35 and 40 are pivoted to their non-separation position.
    The clutch plates 17 and 18 are on the first clutch plate 16 in abutment, so that the movement of the clock, the second hand shaft 14 and thus the second hand 15 can rotate rotatably.
    The heart lever 7 is located with its footprint 11 at a radial distance from the heart cam 12th
    Now, if the control shaft 1 is moved from its normal position to its zeroing position shown in Figs. 3 and 4, thereby the first operating lever 3 and the second operating lever 27 is pivoted from its rest position to its tripping position.
    In this case, on the one hand by the second axis 28 of the second actuating lever 27 removing separating curve 31 of the cam 30 of the first separating lever 33 and pivoted by him and the second separating lever 38 from its non-separation position to its separation position, whereby the first spreading blade 35 and the second spreading blade 40, the second clutch plate 17 and the third clutch disc 18 lift off the first clutch disc 16 and thus separate the second hand shaft 14 and the second hand 15 of the clockwork of the clock.
    On the other hand, immediately following the first arm 6 of the heart lever 7 released from the pin 5 so that it pivot under the spring force of its second arm 9 with its footprint 11 in contact with the heart cam 12 and the heart cam 13 and with her the Second hand shaft 14 and the second hand 15 can pivot to the zero position.
    Opposite the first operating lever 3, the second operating lever 27 has an actuating cam 42 which holds in the rest position of the second operating lever 27 a stop spring 44 pivotable about a stop spring axis 43 counter to a spring force in its inactive position lifted by a balance 45.
    If the second operating lever 27 pivots into its triggering position, the actuating cam 42 pivots out of engagement with the stop spring 44, so that it bears radially against the circulating contour of the balance 45 under the spring force acting on it and brakes it to a standstill.
    Upon a return movement of the control shaft 1 from its zeroing position to its normal position, the actuating cam 42 lifts the stop spring 44 back from the balance 45 and releases it again. With the heart lever 7, the footprint 11 is lifted from the heart cam 12 and the spreading blades 35 and 40 are moved to their non-separation position, so that the movement on the Räderwerkstrieb 25 again the second hand shaft 14 and the second hand 15 rotatably drive.
