    The invention relates to a striking mechanism of a clock with a stop lever 1 which is pivotably mounted at one end about a pivot axis and which has a stop hammer 2 at its other end facing away from the pivot axis, by means of which an elastic sound-producing element can be struck. The stop lever 1 can be driven pivotably against a spring force from a basic position closer to the sound-producing element into a clamping position farther away from the sound-producing element and is then pivotable by the spring force from the clamping position via the basic position into a stop position in which the hammer 2 on the sound-producing element strikes. When pivoting back from the stop position into a blocking position of the stop hammer 2 spaced apart from the sound-generating element, the stop lever 1 can be positively blocked by a blocking device in the blocking position to prevent it from moving into the stop position.

    专利说明:

    The invention relates to a striking mechanism of a clock, with a stop lever which is pivotably mounted at its one end about a pivot axis and which has a stop hammer at its other end facing away from the pivot axis, through which an elastic sound producing element can be struck The stop lever can be driven pivotably against a spring force from a basic position closer to the sound-generating element into a clamping position farther away from the sound-generating element and then pivotable by the spring force from the clamping position via the basic position into a stop position in which the stop hammer strikes the sound-generating element .
    In such striking mechanisms there is the problem that after striking the stop hammer on the elastic sound-generating element, in particular on a gong, the stop hammer bounces back through the elasticity of the sound-generating element and is accelerated again against the sound-generating element. This leads to an unwanted further hitting of the tone-generating element, as a result of which the sound of the first hitting becomes muffled and unclean. In order to avoid this problem, it is known to act on the stop lever from the stop position into the basic position by a spring element which, with its spring force, prevents further hitting. However, this requires an increased force with which the stop lever for striking the stop hammer must be applied to the sound-generating element, since the force of the spring element must also be overcome. This leads to an increase in the required installation space and, by braking the stop lever, negatively affects the impact of the stop hammer on the sound-generating element.
    [0003] The object of the invention is therefore to create a striking mechanism of the type mentioned at the outset, which is simple in construction, has a small overall size and avoids such an unintentional further striking of the stop hammer.
    This object is achieved in that the stop lever can be positively blocked against mobility in the stop position by a blocking device in the blocking position during a pivoting back movement from the stop position into a blocking position of the stop hammer spaced apart from the sound-generating element.
    This design accelerates the stop hammer until it strikes the sound-generating element without braking in the last part of the stop stroke. In this way, the spring force acting on the stop lever can be designed to be lower, which leads to a smaller overall size.
    After striking the elastic sound-generating element, the stop lever is reliably prevented from further unintentional striking of the stop hammer on the sound-generating element by the positive blocking of the stop lever in the blocking position. This does not have a negative impact on the sound of the first hit, so that this sound remains brilliant.
    [0007] The sound-generating element can be a gong spring to save installation space.
    It leads to a simple structure if the blocking position of the stop lever corresponds to the basic position of the stop lever.
    To block the stop lever in the blocking position, the stop lever can have a first latching element in a simple embodiment, from which a second latching element can be grasped from behind, through which the stop lever can be blocked in the blocking position against mobility into the stop position.
    In this case, the second latching element engages behind the first latching element automatically when the second latching element is acted upon by a spring force in the latching direction on the first latching element.
    The second latching element can be moved by the stop lever when it moves into the clamping position out of engagement from the first latching element in order to allow a further intentional striking of the stop hammer on the sound-generating element.
    Here, the second latching element can be locked in its disengaged position from the first latching element by a locking element, this locking being releasable from the stop lever located in the stop position.
    In a simple embodiment, the stop lever can have a locking disk fixedly arranged on it in the area of its pivot axis with an arcuate circumferential contour surrounding the pivot axis, which ends at a locking contour directed radially to the pivot axis, which forms the first locking element, the second locking element being movable radially to the circumferential contour of the locking disk and has latching lever spring-loaded against the circumferential contour of the blocking disk, and the second latching element slides along the circumferential contour of the blocking disk when the stop lever is pivoted back out of the stop position and engages behind the first latching element when the blocking position is reached.
    Saving installation space, the circumferential contour of the locking disk extends concentrically to the pivot axis of the stop lever.
    The locking lever can have a locking projection which can be reached from behind by the locking element and can be locked in the disengaged position of the second locking element by the first locking element, the locking element being disengaged from the locking projection in the stop position of the stop lever by the stop lever.
    To reduce the number of components, the locking disc can have a nose projecting radially over the circumferential contour, through which a locking lever having the locking element can be pivotably acted upon against a spring force, whereby the locking element can be disengaged from the locking projection.
    The stop lever can have a driving pin extending parallel to its pivot axis, by means of which the locking lever can be pivoted against a spring force when the stop lever is moved into the clamping position and the second locking element can be moved out of engagement from the first locking element.
    If the driver pin can be acted upon by a lever arm of a scoop that is pivotably drivable about an axis parallel to the pivot axis of the stop lever and the stop lever can be moved from its basic position into its clamping position, the driver pin fulfills the dual function of pivoting both the locking lever and the stop lever in its cocked position.
    An exemplary embodiment of the invention is shown in the drawing and is described in more detail below. Show it<tb> <SEP> Figure 1 shows a plan view of a striking mechanism with a stop lever in the basic position<tb> <SEP> FIG. 2 shows a plan view of the striking mechanism according to FIG. 1 with the stop lever in the clamping position<tb> <SEP> FIG. 3 an enlarged representation of the section “X” from FIG. 2<tb> <SEP> FIG. 4 shows a plan view of the striking mechanism according to FIG. 1 with the stop lever in the stop position<tb> <SEP> FIG. 5 an enlarged representation of the section “Y” from FIG. 4<tb> <SEP> FIG. 6 shows a side view of an assembly consisting of the driver pin, hammer shaft and blocking disk of the striking mechanism according to FIG. 1<tb> <SEP> FIG. 7 a plan view of the assembly according to FIG. 6.
    The illustrated striking mechanism for a repeater watch has a stop lever 1, which has a stop hammer 2 at one end. At its other end, the stop lever 1 is connected to a screwing point 3 with a plateau 4. At a distance parallel to the screwing point 3, the plateau 4 has a rotatably mounted hammer shaft 5 with which the plateau 4 and with it the stop lever 1 are pivotably mounted.
    A driver pin 6 is arranged coaxially to the screwing point 3 on the plateau 4 and can be driven pivotably by a scoop 7 from a basic position (Figure 1) into a clamping position (Figures 2 and 3). The creator 7 is from a rake, not shown, e.g. a repeater mechanism of the repeater watch can be driven to rotate counterclockwise.
    In the basic position (Figure 1) the stop hammer 2 is at a short distance and in the tensioned position (Figures 2 and 3) at a large distance from a gong spring 8, which is arranged in the pivot plane of the stop lever 1 and 2 stop hammer .
    The scoop 7 pivotable about a scoop axis 9 parallel to the screwing point 3 has a radial scoop arm 10 through which the driver pin 6 can be acted upon and, during the pivoting movement of the scoop 7, the stop lever 1 counteracts the force of a hammer spring 11, not shown in FIG the basic position can be swiveled into the clamping position.
    A locking disk 12 is arranged coaxially on the hammer shaft 5 in a rotationally fixed manner, which has a circumferential contour 13 concentric to the hammer shaft 5 on part of its circumference, which opens into a radially inwardly directed, a first locking element 14 forming locking contour.
    A latching lever 15, which is acted upon by a latching lever spring 16 against the blocking disk 12, which is formed in one piece with the latching lever 15, extends approximately tangentially to the circumferential contour 13.
    The locking lever 15 has a locking contour forming a second locking element 17, which protrudes radially to the locking disc 12 and in the locking position of the stop lever 1, the first locking element 14 can engage behind, whereby the stop lever 1 in a pivoting movement in a stop position in which strikes the stop hammer 2 on the gong 8 is prevented.
    The free-standing end of the detent lever 15, which forms a locking lug 25, has a greater distance from the second detent element 17 to the axis of rotation of the hammer shaft 5, so that the second detent element 17 is the first detent element 14 in the basic position of the stop lever 1, which is also the blocking position is, can engage behind reaching.
    On the movement path of the locking lever 15 from the stop position to the basic position, the second locking element 17 slides on the circumferential contour 13.
    A locking lever 18 extends approximately at right angles to the locking lever 15, which is pivotably mounted at one end about a locking axis 19 and extends tangentially to the circumferential contour 13 of the locking disc 12. The free end of the locking lever 18 forms a locking element 20 which rests on the front side of the free end of the locking lever 15 on the movement path of the stop lever 1 from the stop position to the basic position and in the basic position and has a small distance between its longitudinal side 21 facing the circumferential contour.
    During the further pivoting movement of the stop lever 1 from the basic position to its clamping position, a protruding nose 22 of the locking disk 12 moves radially beyond the circumferential contour 13 out of the pivoting range of the locking lever 18 and so cannot act on this locking lever 18 on its longitudinal side 21. At the same time, the locking lever 15 is moved radially away from the locking disk 12 by the driver pin 6 in such a way that the second locking element 17 is moved radially out of engagement with the first locking element 14.
    In this position of the locking lever 15 this is pivoted so far that the locking element 20 of the locking lever 18 no longer rests on the end face 24 of the free end of the locking lever 15 and the locking lever 18 under the force of a locking spring 23 until it rests on the Circumferential contour 13 of the locking disk 12 can pivot (Figure 2).
    The locking element 20 of the locking lever 18 pivots in front of the locking disc 12 facing side of the locking lug 25 forming the cantilevered end of the locking lever 15 and blocks it in this way lifted from the peripheral contour 13 and the second locking element 17 disengaged from the first locking element 14 brought position that during the pivoting movement of the stop lever 1 from the clamping position into the stop position, the second latching element 17 is prevented from moving into a position engaging behind the first latching element 14 (FIG. 3).
    Thus, the pivoting movement of the stop lever 1 into its stop position and thus the stop hammer 2 can hit the gong spring 8 freely and unhindered.
    When the locking position is reached, the nose 22 of the locking disc 12 acts on the locking lever 18 in such a way that it lifts from the circumferential contour of the locking disc 12 and at the same time moves out of the area of the locking lever 15 forming the locking projection 25 so that the locking lever 15 with the second locking element 17 comes to rest on the circumferential contour 13 and the locking lever 18 with the locking element 20 is opposite the end face of the free end of the locking lever 15 forming the locking projection 25 (FIG. 5).
    Due to the elasticity of the gong spring 8, the stop hammer 2 and thus the stop lever 1 is now bounced back and comes into the basic position, whereby the second latching element 17 reaches the area of the first latching element 14 and engages behind it (Figure 1).
    The latching lever 15 can thus not pivot back into the stop position and lead to a further, then unintentional hitting of the stop hammer 2 on the gong spring 8.
