    The invention relates to an alarm triggering device for a clock, with one of a clockwork rotatably drivable about a first axis and fixed on a first shaft drive wheel, with a frictionally arranged on the first shaft minute wheel, through which a change gear to a to the first axis parallel second axis is rotatably driven, with a coaxially non-rotatably connected to the change wheel first drive, of which an hour wheel around the first axis or a third axis parallel to the first axis can be rotatably driven at a lower speed than the change wheel, with a parallel to the first axis or third axis and to the hour wheel directed first cam of an hour setting wheel, which is with its free face on a concentric sliding circle of the hour wheel in contact, as well as with a cutout formed on the concentric sliding circle of the hour wheel, into which the first cam can be immersed, with a look parallel to r second axis and to the change gear directed second cam of a change wheel rotatable about the second axis, which can be placed under spring action on a setting of the change wheel parallel to the change wheel, which extends on a coaxial pitch circle opposite the second cam.
    Such alarm tripping devices, in which wheels are scanned that rotate faster than the hour wheel, have the advantage of a higher accuracy of the alarm process than alarm tripping devices in which only one wheel is scanned. But they have the disadvantage that they require significant energy from the clockwork, so that this must be designed for a greater energy requirement.
    The object of the invention is therefore to provide an alarm clock triggering device of the type mentioned, which has a simple structure, a high accuracy of the alarm process and enables a reduction in the energy required.
    This object is achieved according to the invention in that the gate extends in its end region close to a waste edge against the direction of rotation of the change wheel inclined by a certain angle of inclination towards the change wheel and ends at the waste edge.
    As a result of this design, the second cam runs downward on the inclined area of the backdrop during the rotation of the change gear. The process can be adjusted via the angle of inclination and the friction conditions between the cam and the inclined gate so that the second cam slides without loss on the inclined plane from the point of view of the clockwork. The energy for this is taken from the spring action on the second cam. This achieves a reduction in the energy required, which means that the size of the clock can also be reduced.
    The change wheel can rotate depending on the selected translation at three or four times the speed of the hour wheel. With the help of the backdrop, this is used to trigger the alarm time more precisely.
    The spring loading serves as the only energy storage device for scanning the faster-running change wheel and as a fixation of the change wheel, which is decisive for the exact alarm time, and for forcing the triggering of the alarm device. This increases the accuracy and reduces the force required to act on the spring and thus the energy requirement that is taken from the movement while the force is being applied to the spring.
    The backdrop can extend in the end region close to the trailing edge by an angle of inclination between 4 ° and 15 °, in particular between 4 ° and 8 °.
    The first cam can dip into the cutout leading to the immersion of the second cam on the waste edge, so that the exact triggering of the alarm triggering device is carried out by the falling of the second cam on the waste edge of the backdrop.
    To immerse the first cam in the cutout of the hour wheel, the hour setting wheel can be arranged freely rotatable and axially displaceable about the first axis or the third axis in a simple design.
    To immerse the second cam on the trailing edge of the backdrop, the hour setting wheel can also engage in a second drive in a simple design, which is freely rotatable about the second axis and is coaxially fixed to the change wheel and can be rotated manually by an actuator , wherein the second drive and the change wheel are axially displaceable together with the hour wheel and the change wheel is spring-loaded towards the change wheel.
    The bias voltage acting on the change wheel is generated in a simple manner in that the change wheel is acted upon towards the change wheel from a free end of a prestressed leaf spring which is firmly clamped at its other end.
    For this purpose, a loading disc can be connected coaxially at a distance parallel to the change wheel side of the change wheel with the change wheel, which is acted upon by the free end of the leaf spring biased against the action disc, the leaf spring with its free end in the direction of rotation of the change wheel in a radial Can extend distance to the second axis of rotation.
    If the leaf spring has a spring tongue extending parallel to its free end, the free end of which is frictionally engaged in the direction of rotation of the change-over adjusting wheel at a distance from the second axis of rotation under bias on the change-over adjusting wheel, then the force-locking contact of the spring balancer is a prevents unwanted turning of the change wheel.
    As soon as the backdrop releases the second cam and the downward movement of the change adjusting wheel and the second cam is initiated due to the tensioned leaf spring, the change adjusting wheel through the relaxing leaf spring, which is not only down but, due to their decreasing bending, also moved a little bit to the left and this movement is transferred to the change gear via the non-positive connection with the spring tongue, also turned a little bit. As a result, the second cam can move freely downwards without dragging against the waste edge of the backdrop. This unimpeded downward movement triggers the alarm triggering device.
    An embodiment of the invention is shown in the drawing and is described in more detail below. 1 shows a perspective illustration of a change release device without alarm display and without alarm setting of a clock; FIG. 2 shows an enlarged perspective illustration of a change wheel with drive and link of the change release device according to FIG 4 shows an enlarged perspective view of the hour wheel and first cam of the change release device according to FIG. 1; FIG. 5 shows a perspective view of the change release device according to FIG. 1 with alarm display; FIG. 6 shows a perspective view of the change release device according to FIG. 1 with alarm setting.
    Figure 1 shows a wake-up device with part of the clockwork. The drive wheel 1 belongs to the clockwork and is rotatably driven about a first axis 2 by a barrel (not shown) at one revolution per hour. On the first shaft 3 of the drive wheel 1 sits a minute wheel 4 with a force fit, which drives an hour wheel 7 that can be rotated about the first axis 2 via a change wheel 5, which is firmly connected to a first drive 6 and rotatable about a second axis 9. The first drive 6 is firmly seated on a second shaft 8 which is parallel to the first shaft 3 and which is rotatably mounted about the second axis 9. An hour tube 10, coaxial with the first axis 2 and on which an hour hand 11 is seated, is firmly connected to the hour wheel 7. A minute hand 12 is firmly connected to the first shaft 3 and thus to the minute wheel 4.
    The change wheel 5 rotates depending on the selected translation with 3 or 4 times the speed of the hour wheel 7. It is used with the help of a backdrop 13 for more accurate triggering of the alarm trigger.
    An hour setting wheel 14 that can rotate about the first axis 2 and a change setting wheel 15 of the alarm triggering device that can rotate about the second axis 9 are coupled via a second drive 16 with the same translation as the change wheel 5 and the hour wheel 7. A second cam 17, which is directed towards the change wheel 5 and slides on a concentric sliding circle of the link 13, is fixedly arranged on the second drive 16 and the change adjusting wheel 15. The backdrop ends at a waste edge 25.
    As Figure 6 shows, the desired wake-up time can be set from an adjusting shaft 21 via an adjusting pinion 22 on the changing adjusting wheel 15 and the hour adjusting wheel 14.
    When the wake-up time is reached, the hour setting wheel 14 and the changing setting wheel 15 are pressed down by a pretensioned leaf spring 18 to the hour wheel 7 or to the setting 13. The hour setting wheel 14 and the changing setting wheel 15 are axially displaceable and can only change their position together. The leaf spring 18 is fixed at its one end and acts with its other free end 19 on an actuation disk 20 arranged parallel to the second drive 16. This actuation disk 20 is firmly connected to the second drive 16 and carries the second cam 17.
    On the hour setting wheel 14, a first cam 23 is arranged which is directed towards the hour wheel 7 and slides along a concentric sliding circle on the hour wheel 7. Shortly before the set wake-up time is reached, the first cam 23 falls into a cutout 24 formed in the hour wheel 7 in the area of the sliding circle.
    At this moment, only the second cam 17 of the change adjusting wheel 15 resting on the gate 13 holds the distance between the changing adjusting wheel 15 and the changing wheel 5.
    FIG. 2 shows the shape of the backdrop 13 in detail. This is designed in its end area 26 in front of the waste edge 25 as an inclined plane with an inclination of approx. 6 °, so that the second cam 17 runs downwards on this inclined plane during the further rotation of the change wheel 5. This process can be adjusted via the angle of inclination and the friction conditions between the second cam 17 and the plane so that the second cam 17 slides without loss on the inclined plane from the perspective of the clockwork. The energy for this is taken from the leaf spring 18.
    Figure 3 shows the triggering on the change wheel 5 in detail. The alarm triggering device is shown shortly before triggering. The second cam 17 is still partially on the link 13. Above the loading disk 20 with the second cam 17, the leaf spring 18 is shown.
    The leaf spring 18 has a parallel to its free end 19 extending spring tongue 27, the free end of which is in the direction of rotation of the Wechselstellrades15 at a radial distance from the second axis of rotation 9 under bias on the changeable wheel 15 in a positive manner. With the aid of the spring tongue 27, unwanted rotation of the change adjusting wheel 15 is prevented. The spring tongue 27 produces a non-positive connection with the change adjusting wheel 15.
    As soon as the backdrop 13 on the waste edge 25 releases the second cam 17 and the downward movement is initiated due to the tensioned leaf spring 18, the change wheel 15 is controlled by the relaxing leaf spring 18, which is not only down but due to their decreasing size Bending, also moved a little bit to the left and this movement is transmitted via the non-positive connection with the spring tongue 27 to the change adjusting wheel 15, also turned a little bit. As a result, the second cam 17 can move freely downward without dragging against the waste edge 25 of the link 13. A wake-up device (not shown) is triggered by this unimpeded downward movement.
    The tension of the leaf spring 18 which follows after the wake-up process is carried out via the hour wheel 7. This function is shown in FIG. 4. The first cam 23 of the hour setting wheel 14, which is hidden in FIG. 4, which fell into the cutout 24 shortly before the wake-up time is reached, meets the end area 26 of the inclined plane in front of the cutout 24. This leads over the course of about 1, 5 hours to raise the hour setting wheel 14 and the change setting wheel 15 and thus to tension the leaf spring 18. During this time, the change wheel 5 has rotated further by 180 °, for example, depending on the translation. Thus, the second cam 17 is raised in good time before it hits the link 13 of the change wheel 5.
    The set alarm time is displayed as shown in FIG. 5 by means of decentralized hour alarm hands 28 and minute alarm hands 29. The minute alarm hand 29 is derived from the position of the change dial 15, which is decisive for the alarm time. This is done via the wheels 30, 31 and 32. The hour display is derived from the hour setting wheel 14 via the wheels 33 and 34.
    For an exact match between the displayed and the real alarm time, the alarm time may only be set in an anti-clockwise direction. The minute wake-up wheel 29 for the exact display of the wake-up time sits frictionally on its fixed axis, not shown. This ensures that a certain position of the change-over adjusting wheel 15 always corresponds to the same display of the wake-up time, regardless of the backlash of the wheels 30, 31 and 32. Since the leaf spring 18 with its spring tongue 27 prevents the changing setting wheel 15 from rotating, the accuracy of the wake-up time is no longer influenced by the backlash. If the change adjusting wheel 15 were not fixed by the leaf spring 18, but only via the friction within the adjusting device or the alarm time display, then the associated tooth play could influence the actual alarm time.
    One possibility of the adjusting device for the alarm time is shown in FIG. 6. The alarm time is set by engaging the changeover adjusting wheel 15 via the adjusting pinion 22. The adjusting pinion 22 is driven by a wheel 33 which is freely rotatable on the adjusting shaft 21 is. Power is transmitted from the actuating shaft 21 with its square 36 in a form-fitting manner to an axially displaceable wheel 34 which is pressed slightly against the wheel 33 by a spring (not shown). The toothings of wheel 34 and wheel 33, which mesh with one another with spring force, ensure that wheel 33 and thus change-over adjusting wheel 15 are only rotated in one direction.
    To set the time in a counterclockwise direction, the hour setting wheel 14 and the changing setting wheel 15 must be moved into their raised position by a device not shown in order not to accidentally adjust the alarm time.
