    Description Technical Field The invention relates to an operating device for watches, in particular a crown mechanism of a watch and a method for producing such.
    PRIOR ART The crown mechanism of a watch allows the various information displayed, such as the time, calendar time, etc., to be set and / or, in particular in the case of mechanical watches, to wind the winding spring. For waterproof watches in particular, it is important that this mechanism is protected against the ingress of water into the inside of the watch. Therefore, there are crown mechanisms that can be screwed onto a housing bush attached in the housing, in order to improve the water resistance of the watch when the crown body is not actuated, as disclosed, for example, in WO 2000/033 144. To set the displayed information and / or to wind the watch, the crown body must first be loosened, i.e. be screwed on. The crown body has an inner recess in which a crown bush is fastened. An actuating element fastened to the actuating shaft is movably arranged in the crown bushing. A spring in the crown bushing between the control element and the crown body forces the control element (and thus the control shaft) and the crown body into a position in which the user can vary the axial position of the crown body and the control shaft when the crown body is detached from the housing bushing. When changing the axial position of the crown body and the adjusting shaft, the recess slides between the outer crown body and the crown bushing on the housing bushing. In order to achieve watertightness, a sealing ring is arranged between the housing bushing and the outer crown body. The crown bush is usually pressed into a recess in the crown body. This has a number of disadvantages. A noticeable enlargement of the indentation causes a noticeable enlargement of the crown to avoid weakening the crown body. In addition, it has been shown that the crown bushing is a wearing part and often breaks out of the crown body.
    [0003] EP 2 031 468 discloses soldering the crown bushing into the recess in the crown body. EP 1 701 225 discloses gluing, soldering or welding the crown bushing into the recess in the crown body. Due to the different materials between the crown body and the crown bushing, gluing and soldering are exposed to high stress due to temperature fluctuations, so that even such crowns wear out quickly. It is also very difficult to weld the crown sleeve to the crown body and it is not mentioned in the documents mentioned how this should be realized, there is usually less than 1 mm space between the crown sleeve and the crown body, so that it can be soldered with conventional soldering - or welding machine is difficult to get into this space. Also create soldering or welding spot or seam unevenness that quickly become dirty on the loosened crown and can therefore lead to corrosion. These bumps generally also mean that the seal at the end of the guide for the housing bushing does not lie cleanly and is therefore even more susceptible to the accumulation of dirt.
    SUMMARY OF THE INVENTION It is an object of the invention to find a crown mechanism which overcomes the problems of the prior art described, in particular which provides a stable and easy to manufacture crown.
    According to the invention this object is achieved with a crown mechanism for operating a setting device of a watch, a watch and a method for producing a crown mechanism according to the independent claims. Welding the outer crown body to the crown bushing has the advantage that the crown bushing is better connected to the outer crown body and is more stable to high torques, since the connection is made with the material of the crown bushing and the outer crown body and not with a foreign material. This reduces the need for maintenance of the crown mechanism. Laser welding also makes it possible to weld in the very small spaces between the crown bushing and the outer crown body. In addition, laser welding enables very clean welding spots or seams, so that contamination and susceptibility to corrosion are reduced, since less dirt can accumulate on the welding seam. This reduces wear on the crown and simplifies maintenance. Laser welding also makes it possible to make the guide recesses between the outer crown body and the crown bushing very small and very deep, which would not be possible with other welding methods.
    [0006] The dependent claims relate to further advantageous exemplary embodiments of the invention.
    In one embodiment, the crown outer body has an inner recess, and the crown bushing is welded to the outer crown body in the inner recess. The crown bushing is preferably welded to the outer crown body on its outer circumference or on an edge of the outer circumference of the crown bushing. This allows a more stable connection and is easier in terms of process technology than welding on the inside of the crown bushing. Since the gap between the inner recess and the crown bushing is very difficult to access, laser welding is particularly well suited for this. The crown bushing and the outer crown body are preferably arranged orthogonally to one another at the welding point. The weld seam is thus arranged in a corner and not in one surface. This allows the weld seam to be better protected, for example with the sealing ring mentioned later,
    CH 714 989 A2 as if the weld seam is arranged in an unprotected area. This allows a solid, permanent welding spot row or seam with the laser.
    In one embodiment, the inner recess has an open end and a closed end, the closed end having a shape which is designed to position and / or align the crown bushing on or in the shape for the welding. This further improves the stability, since the transmitted forces are not only transmitted via the weld seam, but also via the form fit. This form fit also allows the crown bushing to be welded in the correct position and orientation. This is very important for the larger dimensions of a crown, especially the diameter of a crown. Preferably the shape is a protrusion. This has a number of advantages over deepening. First, with the same thickness of the crown, the guide recess for the housing bushing can be made deeper / longer so that the crown is guided more stably and the forces on the crown bushing can be reduced. At the same time, the projection allows the crown sleeve on the edge of the outer circumference of the crown sleeve to be welded to the distal end of the crown sleeve on the inner recess of the outer crown body. The outer shape of the projection preferably corresponds at least partially, preferably completely, to the inner shape of the crown bushing, so that the crown bushing can be positioned on the projection. The shape, in particular the projection, is preferably selected such that the crown bushing cannot be rotated about the axis of rotation after positioning on or in the shape relative to the outer crown body. As a result, the crown bushing forms a positive connection with the shape or the projection. This helps to significantly reduce the high torques that act on the weld seam of the crown bushing. The combination of form and material closure ensures a high quality and permanent connection with less material fatigue due to changing mechanical loads between the crown bushing and the crown outer body. The form fit can be achieved, for example, by a form or press fit.
    In one embodiment, a guide recess is formed between an outer surface of the crown bushing and the inner recess for guiding the crown body on a housing bushing. The crown body, in particular the outer surface of the crown bushing, has a thread which is designed to fix the crown body on a corresponding thread of the housing bushing. The welding is particularly interesting for such crown mechanisms, since when the crown body is screwed to the housing bushing higher torques occur on the connection between the crown bushing and the outer crown body.
    In one embodiment, a sealing ring is arranged at the transition from the inner recess of the outer crown body to the crown bushing so that the housing bushing presses against the sealing ring when the crown bushing is screwed to the housing bushing. This allows both the sealing of the crown mechanism in the screwed state to be improved and possibly also to compensate and protect unevenness caused by the weld seam. Since the unevenness of laser welding seams is significantly less than that of other types of welding, the sealing ring protects the welding seam much better from dirt and other corrosive elements. The sealing ring protects the weld seam particularly well if it is arranged in a 90 ° edge. A sealing ring with a rectangular cross section is therefore preferably used. In addition, the screwing is damped, which has a positive effect on the feel of the crown mechanism.
    In one embodiment, the crown mechanism has a crown body, an actuating device and a spring, the crown body having an axis of rotation about which the crown body can be rotated, the crown body having a crown bushing, the actuating device having an actuating element, the The actuating element is arranged in the crown bushing such that the actuating element can move axially along the axis of rotation of the crown body and rotation of the crown body is transmitted to the actuating element, the spring having a first distal end which rests on the crown body and a second distal end , which rests on the actuating element, so that the spring pushes the crown body and the actuating element away from one another, the crown body and the actuating element being shaped such that a stop is formed for an approximate movement of the crown body and the actuating element, so that the actuating element be i strikes the crown body in an axial position before the spring goes into block. Due to the small dimensions in a crown mechanism, the prior art did not take into account that the spring contained should never go on block. This was found to be a common reason for the crown mechanism to fail. As a particularly good solution to this problem, a stop was chosen for an approximate movement of the crown body and the actuating element, which avoids blockage of the spring.
    In one embodiment, the actuating element has a first distal end and a second distal end opposite the first distal end, the crown bushing having an open end and a closed end, the stop being through the closed end of the crown bushing and the first distal end of the actuator is formed. Preferably, the first distal end of the spring rests on the closed end of the crown bushing and the second distal end of the spring rests on a support surface of the actuating element. This embodiment allows an optimal compromise between function (spring function and stop) and space. The distance in the direction of the axial movement of the actuating element between the bearing surface of the actuating element for the spring and the first distal end of the actuating element is greater than the spring block length, preferably greater than one hundred and five percent of the spring block length, preferably greater than one hundred and ten percent of the spring block length, the Spring block length is the length of the spring when it goes to block. This allows a margin of safety to prevent spring block formation
    Avoid CH 714 989 A2. The distance in the direction of the axial movement of the actuating element between the bearing surface of the actuating element for the spring and the first distal end of the actuating element is less than one hundred and twenty percent of the spring block length, preferably less than one hundred and fifteen percent of the spring block length. Despite this better functionality, this allows the additional space required to be minimized.
    In one embodiment, the inside of the crown sleeve has a first area for guiding the actuating element, the actuating element having a first area for guiding the actuating element in the first area of the crown sleeve, the actuating element having a third area around which the spring is mounted is, wherein the transition from the first region to the third region around which the spring is mounted forms a bearing surface for the second distal end of the spring. The inside of the crown sleeve preferably has a second area, the adjusting element having a second area for guiding the adjusting element in the second area of the crown sleeve, the first area of the adjusting element not fitting through the second area of the inside of the crown sleeve, so that a further stop is designed for a moving movement of the crown body and the actuating element.
    In one embodiment, the crown body has an outer crown body and a crown bushing, the outer crown body having an inner recess with respect to an axis of rotation of the crown body, the crown bushing being arranged coaxially with the axis of rotation of the crown body in the inner recess of the outer crown body, the guide recess between the Inner recess and the crown bush is formed. In one embodiment, the crown body thread is arranged on an outside of the crown bushing and the housing bushing thread is arranged on an inside of the housing bushing. The outside of the crown sleeve preferably has a first area and a second area, the second area of the crown sleeve having a smaller diameter than the first area of the crown sleeve, the crown body thread being arranged in the first area, the inside of the housing sleeve having a first area and has a second region, the first region of the housing bushing having a smaller diameter than the second region of the housing bushing, the housing bushing thread being arranged in the second region. The housing bush body preferably forms at least part of the first region of the housing bushing and preferably at least part of the second region of the housing bushing, the threaded bushing forming at least part of the second region of the housing bushing.
    In one embodiment, the crown mechanism has a crown body and a housing bush. The housing bush is preferably arranged coaxially to the axis of rotation of the crown body. The outside of the housing bush preferably has a first area for fastening in the watch and a second area for guiding the crown body. The housing bush further preferably has a first distal end, the second region being arranged between the first region and the first distal end. The second region of the housing bushing preferably has a circumferential groove in which a sealing ring for sealing between the housing bushing and the guide recess is mounted. The arrangement of the groove for the sealing ring in the housing bushing instead of in the crown body allows the guide recess to be made wider, which simplifies the welding of the crown bushing to the crown outer body. In addition, this allows a wider design of the part of the housing bush protruding from the housing of the watch, which simplifies the use of an inserted threaded bush. In addition, the production of an outer groove is much easier than an inner groove. The assembly of the sealing ring is also much easier in this case. Preferably, at least part of the second area between the groove and a first distal end of the housing bush has an outer guide diameter for guiding the crown body, at least part of the second area between the groove and the first area having the same outer guide diameter for guiding the crown body. These same outer guide diameters in front of and behind the groove have the advantage that the guide recess of the crown body is guided on the housing bush both in front of and behind the groove. This leads to a very stable guidance of the crown body even when pulled out. This also significantly improves the water resistance when pulled out.
    In one embodiment, a sealing ring is mounted in the first region of the housing bush for sealing between the first region of the housing bush and a housing of the watch. This improves the waterproofness of the housing bush.
    In one embodiment, the crown mechanism has a crown body and an adjusting device. The actuating device has an actuating element which is preferably arranged to be axially movable within the crown bushing along the axis of rotation, the actuating element and the crown bushing preferably being shaped such that a first stop is formed and / or a rotation of the crown body is transmitted to the actuating element. The crown mechanism preferably has a spring which presses the crown body away from the actuating element into the first stop. For such crown mechanisms in particular, welding the crown bushing to the outer crown body is advantageous, since the crown body cannot be made from one piece.
    In one embodiment, the actuating element has a first distal end and an opposite second distal end in the direction of the axis of rotation, the actuating device having an actuating shaft, the actuating shaft having a first distal end and an opposite second distal end in the direction of the axis of rotation , wherein the second distal end of the actuating element has a fastening opening, wherein the first distal end of the
    CH 714 989 A2
    Actuating shaft has a tapered area which is fastened in the fastening opening of the adjusting element, the tapering area forming a step which forms a stop for the adjusting element fastened to the adjusting shaft. This allows the position of the adjusting element to be defined much more precisely and thus improves the precision of the stop or the stops of the adjusting element with the crown body. This is particularly important for the stop for an approximate movement of the crown body and the actuating element. First, this stop defines the screwed position between the crown body and the housing bush. If the actuating element is in an imprecise position on the actuating shaft, the thread of the crown body can also be inaccurately aligned with the thread of the housing bushing and thus cause higher abrasion or sluggish turning. Since this stop prevents the spring from forming a block, the precision of the stop is very important, since if the adjusting element is in an imprecise position on the adjusting shaft, the spring may block. This is also important for the stop for a moving movement of the crown body and the adjusting element, since this defines the axial positioning positions of the crown body on the housing bushing.
    The exemplary embodiments described are particularly advantageous in combination with the features of the independent claims, but can also be used advantageously without them. Instead of laser welding, normal welding could also be used.

    Fig. 2 shows the embodiment of the crown mechanism in a released state in the basic position.

    WAYS OF CARRYING OUT THE INVENTION Figs. 1 through 4 show an embodiment of a crown mechanism. The crown mechanism is a special knob, the rotation of which functions differently depending on the axial position of the crown. One of the functions or axial positions is usually an idle, i.e. a rotation of the crown has no consequence for the watch. At least one further function or axial position is designed to wind up the clock and / or to set the time, the calendar and / or other information displayed.
    [0023] The crown mechanism can be used in all types of watches. For example, the crown mechanism can be used in a mechanical watch, a quartz watch, a hybrid watch, or another type of watch. The watch in which the crown mechanism is used or fastened is preferably a wearing watch (e.g. wristwatch or pocket watch), but can also be used in other watches such as table clocks, wall clocks, grandfather clocks, etc. The watch, which contains the crown mechanism, is preferably tight against the ingress of a liquid, in particular watertight. However, the crown mechanism can also be used in other watches that are not sealed against water or other liquids.
    The crown mechanism has a crown body 1, an adjusting device 2, a housing bush 3, a spring 4 and a sealing ring 5.
    The crown body 1 preferably has an axis of rotation about which the crown body 1 can rotate and / or along which the crown body 1 can move axially. The axial movement of the crown body 1 and / or the adjusting device 2 relates to a movement along or parallel to the axis of rotation of the crown body 1 (or the adjusting device 2). An axial displacement along the axis of rotation and / or an adjusting axis of the adjusting device can take place in a first direction 7 (away from the crown bushing 3 or clock) or in a second direction 8 (towards the crown bushing 3 or clock).
    The crown body 1 has a crown outer body 11 and a crown bushing 12.
    The outer crown body 11 is designed to be confirmed by a user of the watch. The actuation of the outer crown body 11 is, for example, a rotation and / or an axial displacement of the crown body 1. The outer crown body 11 has an inner recess 111 in which the crown bushing 12 is arranged. The inner recess 111 is preferably arranged rotationally symmetrically about the axis of rotation of the crown body 1. The inner recess 111 preferably has a cylindrical shape. The inner recess 111 preferably has an open end (in the second direction 8) and a closed end opposite the open end (in the first direction 7). The inner recess 111 thus has a roughly pot shape in which the crown mechanism is at least partially arranged. The inner recess 111 preferably has a shape 112 for positioning and / or
    CH 714 989 A2
    Alignment and / or attachment of the crown bushing 12. This shape 112 is designed here as a projection 112, but can also be designed as a recess or depression. The shape 112 is preferably arranged rotationally symmetrically to the axis of rotation of the crown body 1. Preferably, the (inner) diameter of the inner recess 111 is constant over a large part (> 50%, preferably> 70%, preferably> 80%, preferably> 90%) of the depth of the inner recess 111, i.e. does not change along most of the axis of rotation. As a result, the majority of the inner surface of the inner recess 111 can serve as a sealing, sliding and / or guiding surface for the crown body 1 (on the housing bush 3).
    The outer shape of the crown bushing 12 is preferably rotationally symmetrical about the axis of rotation of the crown body 1. The crown sleeve 12 preferably has a first distal end (in the first direction 7) and a second distal end (in the second direction 8), which is arranged opposite the first distal end. The second distal end of the crown sleeve 12 is open. The first distal end of the crown sleeve 12 is closed. The first distal end is closed, for example, by the outer crown body 11.
    The inner shape or the inner surface of the crown bushing 12 preferably has a first region 121 and a second region 122. The first region 121 of the inner surface of the crown bushing 12 is designed to guide a first region 221 of an actuating element 22 of the actuating device 2 in the crown bushing 12. The first region 121 has a constant cross section and / or a constant diameter (for guiding the actuating element 22) along the axis of rotation. The second area 122 of the inner surface of the crown sleeve 12 is designed to guide a second area 222 of the actuating element 22 in the crown sleeve 12. The second region 122 has a constant cross-section and / or a constant diameter (for guiding the actuating element 22) along the axis of rotation. The first region 121 and / or the second region 122 of the crown bushing 12 allows the actuating element 22 to be guided and / or moved axially relative to the crown body 1. The second region 122 is preferably arranged between the first region 121 and the second distal end, preferably the second region 122 forms the second distal end. The first region 121 is preferably arranged between the second region 122 and the first distal end; the first region 121 preferably forms the first distal end. The cross-sectional shape and / or the diameter of the first area 121 is preferably greater than that and / or that of the second area 122. The cross-sectional shape and / or the diameter of the second area 122 is designed such that the first area 221 of the actuating element 22 does not pass through the second area 122 fits. Thus, with the first area 221 of the actuating element 22 and the second area 122 of the inner surface of the crown sleeve 12, a first stop is achieved between the crown body 1 and the actuating element 22 or the actuating device 2 (if the actuating element 22 or the actuating device 2 is relative to the Crown body 1 in the second direction 8 or the crown body 1 moves relative to the actuating device 2 in the first direction 7). The transition from the first region 121 to the second region 122 preferably forms a step, a flange or a stop. The step forms the stop surface of the crown bushing 12 for the actuating element 22 for the first stop. The inner shape or the inner surface of the first region 121 is designed to non-rotatably engage in the outer shape or outer surface of the first region 221 of the actuating element 22, and / or the inner shape or the inner surface of the second region 122 is designed to rotate non-rotatably in the outer shape or outer surface of the second Intervene area 222 of the actuating element 22. To engage in a rotationally fixed manner means that the engagement is such that rotation of the crown body 1 is transmitted to the actuating element 22. The shape of the first region 121 of the inner surface of the crown bushing 12 and of the first region 221 of the actuating element 22 and / or of the second region 122 of the inner surface of the crown bushing 12 and of the second region 222 of the actuating element 22 can, for example, be a hexagon or any other non-rotationally symmetrical shape his. As a result, the rotation of the crown body 1 is transmitted to the actuating element 22 and thus to the actuating device 2. The second region 122 is preferably arranged at the second distal end of the crown bushing 12.
    The outer shape or the outer surface of the crown bushing 12 preferably has a first region 123 and a second region 124. The first region 123 of the outer surface of the crown bushing 12 is designed to be moved in an axial direction in a first region 35 of an inner surface of the housing bushing 3 along the axis of rotation of the crown body 2 and / or is rotatably supported in the first region 35 of the inner surface of the housing bushing 3 to become. The second area 124 of the outer surface of the crown sleeve 12 is designed to be moved in an axial direction in a second area 36 of an inner surface of the housing sleeve 3 along the axis of rotation of the crown body 2 / and / or is rotatably mounted in the second area 36 of the inner surface of the housing sleeve 3 to become. The first region 123 and / or the second region 124 of the crown bushing 12 allows it to be axially displaced in the housing bushing 3 and / or to be guided therein and / or to be rotated therein and / or to be rotatably supported therein. The cross-sectional shape and / or the diameter of the first region 123 is preferably larger than that and / or that of the second region 124. The cross-sectional shape and / or the diameter of the second region 124 is designed such that it does not pass through (without rotation) second area 36 of the housing bush 3 fits. The transition from the first region 123 to the second region 124 forms a step. Thus, the step of the crown sleeve 12 encounters the step formed by the transition from the first area 35 to the second area 36 during an axial movement in the second direction 8. The first area 123 has an (outside) thread 125. The thread 125 is preferably arranged after the step between the first and second regions 123 and 124. The thread 125 is designed to be screwed to a corresponding thread 362 of the housing bush 3. Thus, the crown body 1 or the crown bushing 12 is formed when it abuts the housing bushing 3 during the axial movement in the second direction 8, by rotating the crown body 1 or the crown bushing 12 with the housing bushing
    CH 714 989 A2 screwed and thus to be fixed. In the screwed state, the adjusting device 2 #, in particular the adjusting element 22 (with its first distal end), is in contact with the crown body 1, in particular the mold 112. 1 shows this screwed position of the crown body 1.
    The guide recess 9 is formed between the (outside of) the crown bushing 12 and the inner recess 111 of the crown outer body 11. The guide recess 9 is designed to be guided on (the second region 32) of the housing bush 3. The guide recess 9 is designed to be rotated and / or axially displaced and / or guided on (the second region 32 and / or the first region 35) of the housing bush 3.
    In one embodiment, the outer crown body 11 and the crown sleeve 12 are formed as two separate parts that are welded together. Compared to other joining techniques, this allows a higher resistance to torsional forces and prevents the crown bushing 12 from breaking out of the crown body 1. The crown bushing 12 is preferably welded to the crown outer body 11 by laser welding. The weld seam is preferably provided on the edge between the closed end of the inner recess 111 of the outer crown body 21 and the outer surface of the crown bushing 12. The inner recess 111 of the outer crown body 1, in particular its closed end, is preferably shaped such that the crown bushing 12 can be inserted into the inner recess 111 in the position to be fastened. The outer crown body 11 preferably has the shape 112 at the closed end of the inner recess. The shape 112 is preferably arranged such that the axis of rotation of the crown body 1 runs through the center of the shape 112. In the case of a protrusion 112, the outer shape of the protrusion 112 corresponds at least partially to the inner shape of the first region 121 of the crown bushing 12. This allows the crown bushing 12 to be positioned on the protrusion 112 (before it is welded). However, it would also be possible to provide a recess in the closed end of the inner recess 111, into which the crown bushing 12 is inserted. However, this embodiment reduces the depth of the inner recess 111 and is therefore less suitable. The crown bushing 12 can be connected to the mold 112 by press or shape fitting, so that the weld seam does not have to bear all the forces of the connection alone. In particular, it is advantageous that the shape 112 is such that (without taking into account the weld seam) it is not possible to rotate the crown bushing 12 on the shape 112 about the axis of rotation. Form 112, e.g. for example, the outer shape of the protrusion 112 could be in the shape of a regular polygon. These (non-circular shapes) reduce the torques that act on the weld seam and thus allow less wear on the weld seam. This crown body 1 can also be used with other crown mechanisms.
    [0033] The crown body 1 preferably has a sealing ring 15. The sealing ring 15 is preferably arranged at the closed end of the inner recess 111 of the outer crown body 21. Preferably, the sealing ring 15 also surrounds the crown bushing 12. The sealing ring 15 is preferably arranged on the edge between the closed end of the inner recess 111 of the crown outer body 11 and the outer surface of the crown bushing 12. Preferably, the sealing ring 15 has a rectangular (e.g. square) cross section. In the screwed position, the crown body 2 preferably presses the sealing ring 15 against the housing bushing 3. In the screwed position, this leads to an (additional) sealing of the watch case against water ingress. This position also has the advantage that the sealing ring 15 can compensate for any unevenness caused by the weld seam due to its elasticity.
    The actuating device 2 is designed to transmit an actuating movement of the crown body 1 to an actuating mechanism of the watch. The crown mechanism allows the adjusting device 2 connected to the crown body 1 to be rotated and / or an axial displacement of the adjusting device 2 connected to the crown body 1. Preferably, the crown body 1, in particular the crown bushing 12, is thus connected to the adjusting device 2, in particular the adjusting element 22 that a rotation of the crown body 1 is transmitted to the actuating device 2. Normally, the adjusting mechanism 500 of the watch (see FIG. 4) and / or the crown mechanism provides at least two axial adjusting positions of the adjusting device 2 connected to the adjusting mechanism 500, preferably three, four or more. A first axial setting position preferably does not fulfill any function of the clock (when the setting device 2 rotates). In a second axial setting position, a first function of the watch is fulfilled. There is preferably a third axial position for a second function and / or a fourth position for a third function. The first function, the second function and / or the third function is, for example, winding up the clock, setting the time and / or setting a calendar. The adjusting device 2 is preferably arranged such that the longitudinal axis of the adjusting device 2 or the adjusting axis is arranged parallel, in particular coaxially to the axis of rotation of the crown body 1.
    The adjusting device 2 preferably has an adjusting shaft 21 and the adjusting element 22.
    The actuating element 22 has the first area 221, the second area 222 and a third area 223.
    The first region 221 is designed to be guided in the first region 121 of the inner surface of the crown bushing 12. The first region 221 has (for guiding the actuating element 22) a constant (outer) cross section and / or diameter along the axis of rotation, which preferably corresponds to the inner cross section and / or the inner diameter of the first region 121 of the crown bushing 12. The second area 222 is designed to be guided in the second area 122 of the inner surface of the crown bushing 12. The second area 222 (for guiding the actuating element 22) along the axis of rotation has a constant cross section and / or a constant diameter, which preferably corresponds to the inside cross section and / or the inside diameter of the second area 122 of the crown bushing 12. The first area 221 and / or the second area 222 of the actuating element 22 allows guidance and / or
    CH 714 989 A2 axial movement of the actuating element 22 relative to the crown body 1. The cross-sectional shape and / or the diameter of the first area 221 is preferably larger than that and / or that of the second area 222. The cross-sectional shape and / or the diameter of the first area 221 is designed such that the second region 122 of the crown bushing 12 does not fit through the first region 221. This achieves the first stop already described between the crown body 1 and the actuating element 22 or the actuating device 2. The transition from the first region 221 to the second region 222 preferably forms a step or flange. The step forms the stop surface of the actuating element 22 for the crown bushing 12 for the first stop. The shape of the first region 221 is designed to be held in a rotationally fixed manner in the inner shape of the first region 121 of the crown bushing 12, and / or the shape of the second region 222 is designed to be rotationally fixed in the inner shape of the second region 122 of the crown bushing 12 ,
    The third area 223 is designed to hold a spring 4. The spring 4 is preferably a spiral spring. The spring 4 is thus arranged between the first region 121 of the inner surface of the crown bushing 12 and the third region 223 and / or around the third region 223 of the actuating element 22. The third region 223 thus holds the spring 4 in the correct position, preferably coaxially with the adjusting axis or the axis of rotation of the crown body 1. The third region 223 thus forms a type of pin on which the spring 4 is inserted. The cross-sectional shape and / or the diameter of the first region 221 is preferably larger than that and / or that of the third region 223. The transition from the first region 221 to the third region 222 preferably forms a step. The step forms a contact surface of the actuating element 22 for a second end of the spring 4 (lying in the second direction 8). The first end of the spring 4 (lying in the first direction 7) lies on the crown body 1, in particular on the mold 112. When the crown body 1 is screwed to the housing bush 3, the first distal end of the actuating element 22 is in contact with the crown body 1. The first distal end of the actuating element 22 thus forms the second stop between the actuating element 22 and the crown body 1 made of C if the actuating element 22 or the actuating device 2 is relative to the crown body 1 in the first direction 7 or the crown body 1 is relative to the actuating device 2 moved in the second direction 8). When the crown body 1 is detached from the housing bush 3 (screwed on), the spring 4 presses the crown body 1 away from the actuating element 22. That is, as soon as the thread 362 of the housing bushing 3 detaches from the thread 125 of the crown bushing 12, the crown body 1 jumps away in the axial direction in the first direction 7 until the second region 122 of the crown bushing 12 abuts the first region 221 of the actuating element 22 (first stop). The axial position of the crown body 1 and the adjusting device 2 can now be changed in this released position. The third region 223 preferably ends with the first distal end of the actuating element 22. The first region 221 is preferably arranged (in the axial direction) between the second region 222 and the third region 223.
    In a preferred embodiment, the crown mechanism is designed such that (with an axial movement of the crown body 1 towards the housing bush 3) the actuating element 22 strikes the crown body 1 before the spring 4 goes into block. The axial movement of the crown body 1 is in particular a screwing movement in which the crown body 1 is screwed onto the housing bush 3. It has been shown that the use of the (first distal end of) the actuating element 22 as a stop (on the crown body 1) in order to avoid that the spring 4 goes into block allows an optimal use of the available space. The length between the contact surface of the spring 4 on the adjusting element 22 and the stop surface of the first distal end of the adjusting element 22 (pin length) is greater than the length of the spring 4 on the block (spring block length). The greater length of the pin means that the first distal end of the actuating element 22 strikes the crown body 1 before the spring 4 goes into block. This prevents the spring 4 from going into block and is thus worn out more quickly. This will significantly improve the life of the spring 4. The pin length is preferably at least 5%, preferably at least 10%, greater than the spring block length. This information is to be interpreted taking into account the dimensional tolerances. Above these pin lengths, spring block formation or other blocking of the spring is avoided with a high degree of certainty. The pin length is preferably at most 20%, preferably at most 15%, greater than the spring block length. An optimal use of space is achieved below these tenon lengths.
    The (lying in the second direction 8) second distal end of the actuating element 22 preferably has a fastening means for (non-rotatably) connecting the actuating element 22 to the actuating shaft 21. The fastening means is preferably a fastening opening. The fastening opening is preferably arranged coaxially with the adjusting axis of the adjusting device 2 or the adjusting element 22. The fastening opening is preferably a blind hole. The fastening opening preferably has an internal thread into which a corresponding thread of the adjusting shaft 21 can be screwed. The ring formed by the distal end of the actuating element 22 around the fastening opening preferably has a flat stop surface for the actuating shaft 21.
    The adjusting shaft 21 has a first distal end (in the first direction 7) and a second distal end (in the second direction 8). The first distal end is designed to be connected (non-rotatably) to the actuating element 22. This is preferably achieved by means of a threaded connection between the second distal end of the actuating element 22 and the first distal end of the actuating shaft 21. For this purpose, the first distal end of the actuating shaft 21 preferably has an (outer) thread which is screwed to the (inner) thread of the actuating element 22. The adjusting shaft 21 preferably has a tapered region 212 at the distal end 21. The thread of the adjusting shaft 21 is preferably arranged in the tapered region 212. The transition from the tapered region 212 to the remaining part of the actuating shaft 21 (in the second direction 8) forms a step or a stop 211. The thread of the adjusting shaft 21 preferably extends in the first direction 7 following the step 211. This step or the stop 211 forms
    CH 714 989 A2 a stop for the control element 22, in particular for the stop surface of the control element 22. As a result, the control element 22 can be screwed against the step 211 and the screwed position and / or orientation of the control element 22 on the control shaft 21 is well defined. This has the advantage that the position of the control element 22 on the control shaft 21 and thus the position of the first distal end of the control element 22 and thus the control device 2 is exactly defined. Thus, the stop position described above between the distal end of the actuating element 22 and the crown body 1 can be defined without major inaccuracies in order to avoid the block formation of the spring 4.
    The second distal end is designed to be connected to an actuating mechanism 500 of the watch. The second distal end of the actuating shaft 21 is preferably plugged onto a connecting piece 510 of the actuating mechanism 500 in order to achieve the connection.
    Preferably, the actuating shaft 21 and the actuating element 22 are two different parts which are connected to one another. However, it is also possible for the adjusting shaft 21 and the adjusting element 22 to be made from an integral piece.
    The housing bush 3 is designed to be fastened in a housing 400 of the watch. Fig. 4 shows an embodiment of a fastening of the housing bush 3 in the clock. 1 to 3, the housing bush 3 is only drawn in broken lines.
    The housing bushing 3 has a first region 31 and a second region 32 on the outside.
    The first region 31 is designed to be fastened and / or countersunk in the housing 400 of the watch. For this purpose, the first region 31 preferably has a thread 34 which is screwed into the (thread 411 of) the housing (s) 400 of the watch. However, other fastening methods are also possible. The second area 32 is designed to protrude from the housing 400 of the watch and / or to guide the crown body 1 (with its guide recess 9). The first area 31 and / or the second area 32 are / are preferably arranged rotationally symmetrically about the symmetry or longitudinal axis of the housing bushing 3 and / or about the axis of rotation of the crown body 1 or the adjusting device 2. The symmetry or longitudinal axis of the housing bush 3 is arranged parallel, in particular coaxially to the axis of rotation of the crown body 1 or the adjusting device 2. The diameter of the first region 31 is preferably smaller than that of the second region 32. The housing bush 3 has a step or a flange 38 between the first region 31 and the second region 32. A sealing ring 6, preferably an O-ring, sits on the first region 31 (between the flange 38 and the thread 34). When the housing bushing 3 is fastened in the housing 400, the housing bushing 3 presses the sealing ring 6 against the housing 400, so that the sealing of the gap between the housing bushing 3 and the housing 400 is improved.
    The housing 400 preferably has a middle housing part 410, an upper housing part 420 and a lower housing part 430, which are sealingly connected to one another, preferably screwed together. The housing 400, preferably the housing middle part 410, has a fastening opening for the first part 31 of the housing bush 3. The fastening opening in the housing 400 preferably has a first region 411 with a first (inner) diameter, a second region 412 with a second (inner) diameter and / or a third region 413 with a third (inner) diameter. The first diameter is smaller than the second and / or third diameter. The second diameter is smaller than the third diameter. The first region 411 preferably has an (internal) thread for receiving the thread 34 of the housing bush 3. The second area 412 is designed to support / hold the sealing ring 6 between (the first part 31) of the housing bush 3 and (the second area 412) the fastening recess. The distance between the first part 31 of the housing bush 3 and the second region 412 of the fastening recess is preferably smaller than the thickness of the sealing ring 6 in the non-compressed state, so that the second region 412 presses the sealing ring 6 against the first part 31 of the housing bush 3. The transition from the second region 412 to the third region 413 preferably forms a step or a flange 414. The inner diameter of the second region 412 and / or the flange 414 is preferably smaller than the outer diameter of the flange 38 of the housing bush 3, so that the flange 38 presses against the flange 414 when the housing bush 3 is fastened or screwed into the fastening opening of the housing 400. The third region 413 preferably has a shape 415 which corresponds to the shape of the second distal end of the outer crown body 11, so that the shape 415 follows the shape of the second distal end of the outer crown body 11 and / or bears against it when the crown body 1 with the Housing bush 3 is screwed.
    The second region 32 of the housing bush has a groove 33 shortly before the first distal end (in the first direction 7). A sealing ring 5, preferably an O-ring, is mounted in the groove 33. The groove 33 provides a limitation in the first direction 7 and in the second direction 8. In particular, the groove 33 is not open towards the first distal end. This limitation preferably has the same height in the first direction 7 and in the second direction 8. The outer diameter of the second region 32 is preferably the same at the two boundaries of the groove 33. Both a part of the second region 32 between the groove 33 and the first distal end of the housing bush 3 and at least a part of the second region 32 between the groove 33 and the flange 38 are preferably shaped such that both parts contribute to guiding the crown body 1 , This is preferably achieved in that the at least part (preferably more than 30%, preferably more than 50%, preferably more than 70% thereof) of the second region 32 between the groove 33 and the first distal end of the housing bush 3 and the at least a portion (preferably more than 30%, preferably more than 50%, preferably more than 70%) of the second area 32 between the groove 33 and the flange
    CH 714 989 A2 have the same outside diameter. This leads to a very stable guidance of the crown body 1. Even when the crown body 1 is pulled out to the maximum extent, the crown outer body 11 still lies both on the part of the second region 32 between the groove 33 and the flange 38 and on the part of the second region 32 between the groove 33 and the first distal end. This “two-point support” with a sealing ring arranged in between also significantly improves the water resistance when the crown body 1 is pulled out (to the maximum), even under the influence of lateral forces. The groove 33 is preferably deeper than 50%, preferably 60%, preferably 70%, preferably 80%, preferably 90% of the thickness of the sealing ring 6 in the uncompressed state. This also allows a very stable guidance to be combined with a very high level of water resistance. The width of the groove 33 is preferably wider than the height of the sealing ring 5. The arrangement of the groove 33 in the housing bushing 3 has the advantage over the arrangement in the crown outer body 11 that the guide recess 9 can be made wider. On the one hand, this allows the outer crown body 11 to be welded to the crown bushing 12. On the other hand, this permits optimized guidance and watertightness. The outer groove 33 in the housing bushing 3 is also much easier to manufacture and the sealing ring 5 is easier to fit therein than the production of an inner groove and the mounting of the sealing ring 5 therein.
    The first distal end of the housing bush 3 has a recess 39 for the sealing ring 15. The first distal end of the housing bushing 3 is ring-shaped, the recess 39 forming an inner ring and being delimited on the outside by an outer ring which is longer in the first direction 8. As a result, the part of the second region 32 between the groove 33 and the first distal end for guiding the crown body 1 is extended, and thus the guidance and stability against lateral forces in the extended state is further improved without having to forego the function of the sealing ring 15. If the crown body 1 is screwed to the housing bushing 3, the first distal end of the housing bushing 3, in particular the recess 39, presses on the sealing ring 15 and additionally seals the gap between the housing bushing 3 and the crown bushing 12.
    The housing bushing 3 has a first region 35, a second region 36 and a third region 37 on the inside.
    The first area 35 is designed to guide the first area 123 of the outside of the crown bushing 2 and / or to move and / or rotate it axially. The second region 36 is designed to guide the second region 124 on the outside of the crown bushing 2 and / or to move and / or rotate it axially. The first region 35 has a larger inner diameter than the second region 36. The inner shape of the first region 34 and the second region 36 is preferably rotationally symmetrical or (circular) cylindrical.
    The second region 36 has an (internal) thread 362, which is designed to be screwed to the thread 125 of the first region 123 of the crown bushing 12. The thread 362 is preferably arranged following the transition to the first region 35.
    In a first exemplary embodiment, the second region 36, preferably the housing bush 3, is formed in one piece and the thread 362 is cut into the first region 36. In this embodiment, the housing bush 3 is preferably made of an austenitic, stainless steel. In a second exemplary embodiment, the housing bush 3 has a housing bush body and a threaded bush 361. The thread 362 is cut into the threaded bush 361 and the threaded bush 361 is inserted and fastened in the housing bush 3. This attachment is, for example, a press or form fit, welding (e.g. laser welding), soldering or gluing. This second exemplary embodiment allows the housing bush 3 to be produced from a different material than the threaded bush 361. For example, the housing bushing 3 can be made of a soft or hard-to-process material, while the threaded bushing 361 is made of a hard and / or hard-to-process material. For example, the housing bushing 3 can be produced from a noble metal (gold, platinum), titanium, a ceramic, a metal glass, etc., while the threaded bushing 361 is produced from a material that is advantageous for threads.
    Preferably, at least the thread 362, preferably the threaded bush 362 or the housing bush 3 is made of a metal, preferably a steel, preferably an austenitic, stainless steel. The austenitic, stainless steel is preferably a chromium steel (Cr steel), preferably with more than 2.5% Ni (nickel), preferably with molybdenum (Mo), preferably with a material number starting with 1.44 (ie without titanium (Ti) and Niobium (Nb)), for example stainless steel 1.4435, is used. At least the thread 362, preferably the threaded bush 362 or the housing bush 3 is preferably surface-hardened. At least the thread 362, preferably the threaded bush 362 or the housing bush 3 is preferably made of a material that is surface-hardened. The material is preferably a metal, preferably a steel, preferably an austenitic, stainless steel. The surface hardening is preferably nitriding (often also referred to as nitriding). Nitriding increases the hardness of a surface of a metal by diffusing nitrogen (sticking on) and / or carbon (carburizing). The diffusion of nitrogen and carbon is also referred to as teniferation or nitrocarburizing. The nitrogen and / or carbon is preferably diffused in at temperatures below 800 ° C., preferably below 700 ° C., preferably below 600 ° C., preferably below 550 ° C., preferably below 500 ° C. The nitrogen and / or carbon is preferably diffused in at temperatures above 200 ° C., preferably above 300 ° C., preferably above 400 °, preferably above 450 °. A particularly advantageous embodiment of nitriding or teniferating is colsterizing. Kolsterizing here means surface hardening, which is caused by carbon diffusing into an austenitic, stainless steel (preferably with a
    CH 714 989 A2
    Temperature less than 500 °) is reached. The carbon is preferably dissolved in the interstitial sites of the steel and thus forms carbides which generate compressive stresses in the surface and in some cases significantly increase the surface hardness. This surface hardening increases the hardness of the thread 362 or the threaded bush 361 and thus reduces the friction, the abrasion and allows grease-free threads to be used. Thus, at least the thread 362, preferably the threaded bush 362 or the housing bush 3, is preferably nitrided or teniferated, in particular padded.
    The third region 37 has an opening through which the adjusting device 2, in particular the adjusting shaft 21, runs. The third region 37 preferably has a (non-rotationally symmetrical) inner shape (e.g. hexagonal) so that a turning tool (e.g. a hexagon) can engage in this inner shape and the housing bush 3 can thereby be screwed into the housing 400.
    The function of the crown mechanism will be briefly described below. The crown mechanism can be in a screwed state (see FIGS. 1 and 4) and in a released state (see FIGS. 2 and 3). The crown mechanism can be in a basic position (see FIGS. 1 or 4 and 2) and in an extended position (see FIG. 3).
    In Fig. 1, the crown body 1 is screwed to the housing bush 3. In this screwed state, the crown body 1, in particular the outer crown body 11, in particular the shape 112, abuts the actuating device 2, in particular the actuating element 22, in particular the first distal end thereof. The second stop of the actuating element 22 is thus in the struck state. The second stop of the actuating element 22 with the crown body 1 thus defines the position of the crown body 1 relative to the actuating element 22 or the actuating device 2. In the screwed state, the first distal end of the housing bushing 3 presses against the sealing ring 15. The crown mechanism is thus in the screwed state secured twice by the sealing rings 5 and 15 against water ingress. In the screwed state, the crown mechanism, in particular the adjusting device 2, is in an (axial) basic position. In this basic position, a rotation of the crown body 1 and thus the setting device 2 does not lead to a functional change of the clock, i.e. the rotation of the control shaft 21 is not transferred to other mechanical functional devices. When the crown body 1 is screwed into the screwed state and when the crown body 1 is released from the screwed state, high torques sometimes occur in the crown body 1. Frequent actuation of the crown mechanism can result in very high stress on the crown body 1. Longevity under these extreme conditions is ensured in particular by welding the outer crown body 11 and the crown bushing 12. When using an upholstered threaded bush 361, abrasion in the threads 362 and 124 is avoided and lubrication of these threads is not necessary. This facilitates the maintenance and care of the crown mechanism.
    In order to bring the crown mechanism into the released state, the crown body 1 is rotated or screwed out of the housing bush 3. During the screwing on, the crown body 1 moves away from the housing bush 3 and / or from the adjusting device 2 / adjusting element 22 in the first direction 7. The adjusting device 2 does not move and remains in the basic position. When the thread 124 of the crown bushing 12 is unscrewed from the last turn of the thread 362 of the housing bushing 3, the spring 4 presses the crown body 1 from the housing bushing 3 into the released state (see FIG. 2). In this released state, the actuating element 22 and the crown bushing 12 are now in place (first stop of the actuating element 22).
    When the crown body 1 is pulled out in the released state (in the first direction 7), the actuating device 2, in particular the actuating element 22 (due to the engagement of the second region 122 of the crown bushing 12 in the between the first region 221 and the second region 222 of the actuating element 22 formed step). In the released state, the axial displacement of the crown body 1 (in the first direction 7) thus causes an axial displacement of the actuating device 2 and thus of the actuating shaft 2 and the actuating mechanism 500 of the watch (in the first direction 7). As a result, the crown mechanism and thus the adjusting mechanism 500 of the watch can be moved into the axial adjusting positions (specified by the adjusting mechanism). In each axial position, a (different) function of the watch can be carried out by rotating the crown body 1. If the crown mechanism is in the released state and the actuating device 2 is still in the basic position (see FIG. 2), the watertightness of the crown mechanism is ensured by the sealing ring 5. Since both at least a part of the second area 32 between the groove 33 or the sealing ring 5 and the first distal end of the housing bush 3 and at least a part of the second area 32 between the groove 33 or the sealing ring 5 and the first area 31 in the inner recess 111 or the guide recess 9 of the crown body 1 are guided, a very stable guidance of the crown body 1 is achieved. As a result, the crown body 1 is very stable against lateral forces, in particular against shear forces. This significantly improves the tightness of the crown mechanism with lateral forces.
    3 shows the crown mechanism in the maximum pulled-out axial setting position. Even in this position there is at least a part of the second area 32 between the groove 33 or the sealing ring 5 and the first distal end of the housing bushing 3 and at least a part of the second area 32 between the groove 33 or the sealing ring 5 and the out first region 31 in the inner recess 111 or the guide recess 9 of the crown body 1. This allows maximum watertightness even in the maximum pulled-out position of the crown mechanism.
    CH 714 989 A2 The crown mechanism is preferably manufactured and / or assembled as follows. First the individual parts are manufactured.
    The sealing ring 6 is mounted on the first region 31 of the housing bush 3. The housing bush 3 is preferably fastened in the fastening recess of the housing 400 of the watch. The housing bushing 3 is preferably fastened such that the position of the housing bushing 3 in the housing 400 is fixed and does not permit any axial displacement or rotation. For this purpose, a tool is preferably inserted into the third area 37 of the housing bush 3 and screwed into the fastening opening.
    The actuating element 22 and the spring 4 are inserted into the crown bushing 12 from the first distal end. The crown bushing 12 is then connected to the outer crown body 11. This connection is preferably made by welding (see above). The sealing ring 5 is pushed onto the outside of the crown bushing 12 until it lies against the closed end of the inner recess 111.
    The control shaft 21 is screwed into the control element 22. This can be done before or after inserting the actuating element 22 into the crown bushing 12.
    The sealing ring 5 is mounted in the groove 33 on the second region 32 of the housing bush 3.
    The component consisting of the crown body 1, the actuating device 2 and the spring 4 can now be mounted on the housing bushing 3. For this purpose, the adjusting shaft 21 is guided into the opening formed by the third area 34 and the guide recess 9 is inserted into the second area 32 of the housing bush 3. Since the sealing ring 5 is stable in the deep groove 33, the assembly of the crown body 1 (with the spring 4 and the adjusting device 2) is simple and easy.
