    Description: The invention relates to a watch with a crown system, which comprises a shaft with a displacing part, according to the preamble of claim 1.
    PRIOR ART [0002] Wrist- or pocket watches, which are designed mechanically, usually draw the energy required for operation from a spring, which has to be tensioned or pulled up at regular intervals. If this is not done, the clock will stop and it must be reset if necessary. This is particularly associated with great effort when the clock is still connected to other elements, such as a calendar, moon phases or the like.
    The mounting of a wristwatch is done by an outside of the watch case, sitting at the end of the pendant, mounted on the elevator shaft thumbscrew, which is referred to in the jargon as "crown" or "winding crown". In automatic watches, this is also achieved via an assembly of the movement, which spans the spring via a transmission by the movement of the clock. By turning the crown, a tension spring can be tensioned and the energy required for the continuous operation of the watch can be stored.
    In addition to the winding of the clock can usually be adjusted by pulling out the crown and the hands to - once the clock has stopped - again set the correct time of day. Often crowned crowns are also used to set the moon phase, day of the week and month for more complicated clocks.
    A well-known problem of crowns is their susceptibility to mechanical damage, as these usually protrude laterally from the watch case. To prevent damage to the crown, many embodiments of watches on so-called shock horns. These are on both sides of the respective winding crown on watch case arranged or molded projections that prevent damage to the shaft on which the elevator crown is located at a mechanical stress of the clock in the crown area. Alternatively, the watch may be equipped with a bracket to protect the crown from mechanical damage. A disadvantage of these safeguards is that they make the clock not only heavier, but also chunkier, which adversely affects the appearance of the clock.
    In principle, it would be conceivable to sink the crown in the watch case. However, in conventional mechanical movements of the displacement of the elevator shaft is limited to a few millimeters. This limited displacement of the elevator shaft would not be sufficient to bring the crown from the sheltered rest position to a lying outside the watch case working position in which the crown could be operated by the watch carrier.
    DE-OS-3 936 942 discloses a push-button assembly for actuating a controllable element of a watch, with a radially projecting from the watch case key top, which is arranged axially displaceable. At the key top an actuating plunger is arranged, which is displaceable by means of the key head through a recess in the watch case axially into the housing interior and through which the controllable element is actuated. In this case, the key head and actuating plunger are spring-loaded towards the interior of the housing. Key head and actuating plunger are axially displaceable against each other against a spring force. When the housing of the key head housing farer position of the actuating plunger is blocked in its housing outer position by a housing-fixed locking element. When the housing closer to the position of the key head, the locking element is movable by the key head in a blocking the actuation plunger repealing position. In DE-OS-3 936 942, the described axial movement is thus the pusher stroke in order to be able to trigger the switching functions. In the rest position, the crown head is outside the watch case.
    WO 2005/038 538 shows a control device with a pressure crown for a watch with an opening having a support member which can be attached to the housing of the clock or the watch case itself represents. A rotary drive part, which can be connected to the clock (M) of the clock, serves to control the first and second functions of the clock. A crown comprising a head and an extension connected to the head is movably mounted with respect to the support member in the opening thereof. The extension can interact with a control of a third function of the watch, which is located inside the watch case. Further, coupling means are provided to connect the driving part and the extension of the crown in rotation and in translation in the pulling direction, wherein the crown, when the clock is equipped with the control device, can assume a first stable and a second stable drawn axial position which the rotation of the driving part, which is predetermined by the crown, the first and the second function controls. The crown may also be slid from the first axial position to a second axial position for activation of the control independently of the first and second functions controlled by the drive member. First elastic means are provided between the driving part and the head of the crown. Their force is sufficient to overcome the resistance that is provided by the drive part in the transition from the second axial position of the crown in the first. Second elastic means are arranged between the support part and the head of the crown. The second elastic means are compressed in the transition from the first axial position of the crown to the second position for activation of the control to return the crown to the first axial position after the shear stress applied to the crown has subsided. Again, the crown is not sunk in the housing in the normal position. The position next to the housing is only exercised when the trigger function is exercised. It should also be noted that the control is not used to lock the crown in the rest position.
    Swiss Patent No. 241 963 discloses a pusher for the operation of the chronograph functions (start-stop-zeroing) of a timepiece. In contrast to this, a crown system is concerned with the setting of the date, the time or the elevator of the clock. The pusher of CH patent no. 241 963 has a shaft on which a sleeve is arranged axially movable. The sleeve is received in a tube which protrudes from the watch case, axially movable. Attached to the tube is a crown head, which is biased by a spring, which is supported on the tube, in a housing distal end position. By pressing the crown head, the shaft can interact with a rocker to make adjustments to the clock.
    OBJECT [0010] Consequently, there is a need for a watch in which the winding crown is well protected from mechanical damage.
    Description: The invention relates to a watch with a watch case, a movement recorded in the watch case and an opening for receiving a crown system. In the opening, a crown system is used which has a shaft, preferably an elevator shaft, and a crown head. Mounted on the shaft is a displacement part, which is axially displaceable relative to the shaft. The crown head is arranged on the displacement part and can assume at least first and second stable axial positions. The first axial position is a housing inner position of the crown head, in which this substantially completely or at least largely disposed within the watch case, and the second axial position is a housing outer position of the crown head, in which this is arranged substantially outside the watch case, so that he Thumb and index finger can be detected.
    According to the invention, a crown system according to the preamble of claim 1, characterized in that the first housing near axial displacement position is the rest position, in which the crown head is largely accommodated in the watch case. In the context of the present invention, the term "accommodated in the watch case" is understood to mean that the crown head is received in the rest position for at least 50%, preferably at least 60% and particularly preferably at least 75% of its axial extent within the periphery of the watch case. Preferably, however, the crown head in the rest position is substantially complete, i. At least 90% of the axial extent, housed in the watch case. As a result, the attachment of so-called "shock horns" on both sides of the crown head can be dispensed with. This embodiment has the advantage that the crown head is recessed in the rest position in the watch case, since the shaft is telescopically adjustable in length. This allows the crown head to cover a greater displacement than is the case with conventional crown systems.
    Conveniently, the sliding part on an engaging means, which can cooperate with an elastic means and allows a locking of the shaft in the rest position. Such a means of attack may be for example a notch, bulge, thickening, annular groove or a projection. In cooperation with a latch or a spring element, the crown can be detected in the rest position, i. assume a stable axial locking position.
    Between the crown and the shaft, a displacement part is present, which allows a displacement of the crown head relative to the shaft. The displacement part may for example be realized by a sleeve which is arranged on the crown and is guided axially displaceably on the shaft. Such a guide device can be produced inexpensively.
    According to a particularly preferred embodiment, a spring element is provided between the shaft and the crown, which moves the crown arranged on the displacement part into an extended working position, e.g. Elevator and / or adjustment position, pretensioned. This embodiment has the advantage that the crown can automatically drive out of the watch case as soon as the locking device, which holds the crown in the rest position, is released. An advantageous embodiment therefore provides to arrange the spring element in an axial bore of the shaft. Conveniently, the spring element is held by the crown or a closure member in the bore.
    Advantageously, the crown is designed as a hollow cylinder closed on one side, in which the sliding part is used. If there is an annular space between the rear portion of the sliding part and the wall of the hollow cylinder, a retaining element, e.g. Tubus, be included in the annulus.
    Preferably, the shaft is at least two parts and preferably designed at least three parts. This brings advantages in the production and assembly with it.
    Advantageously, the displacement part in a tube which is insertable into a watch case, guided axially displaceable. It is also conceivable, however, that the tube is part of the watch case is resp. the latter is designed accordingly. Through the tube, the sliding part and in the displacement part axially displaceable (elevator) shaft are set in the watch case. Conveniently, the rear part of the tube resp. the corresponding watch case part in the
    Rest position of the crown system received in the annular space between the inner wall of the crown head and the sliding part.
    To be able to grasp the crown well with your fingers, the crown has knurls. In addition, the rear end of the crown is formed by a radially projecting annular bead.
    According to a preferred embodiment, the tube is a certain distance, preferably at least 1 mm and more preferably at least 2 mm set back from the periphery in the watch case, so that the crown is substantially accommodated in the watch case. Preferably, the crown is arranged in the rest position within the periphery of the watch case. However, it is also conceivable that the crown in the radial direction protrudes a maximum of 3 mm, preferably less than 2 mm, and most preferably less than 1 mm beyond the periphery of the watch case. As the periphery of the watch case, the imaginary continuation of the watch case on the (radial) opening for receiving the crown system is to be understood, if the crown system is not used. In an oval watch case, the periphery of the same would correspond to a uniform continuation of the radius of curvature of the watch case, with a rectangular basic shape of a watch case a straight line (watch case edge).
    Advantageously, a recess is provided on the back of the watch case in the region of the crown, so that at least the edge of the crown to pull it out is accessible.
    Advantageously, a spring element is provided in the watch case, which is arranged so that it can cooperate with the engagement means in the rest position of the crown system. By the spring element is a cost-effective and reliable locking of the shaft in the rest position possible.
    An embodiment of the invention will now be described with reference to the drawings. It shows:
    1 shows a cross-section of a crown system according to the invention with a crown and an elevator shaft axially slidably received in the crown;
    Fig. 2: the crown system in an exploded view;
    FIG. 3 shows the crown system of FIG. 1 installed in a watch case; FIG. and
    4 shows a perspective view of the crown system used in the watch case of a watch, parts of the watch which are not essential to the invention being omitted for the purpose of a clearer representation.
    The crown system 11 shown in FIGS. 1 and 2 comprises a crown 13 and arranged on the crown 13 elevator shaft 15, wherein the crown 13 is guided axially displaceably on the elevator shaft 15. That is, the crown 13 can be moved from a retracted rest position, in which it is most or preferably completely contained in a watch case, in an extended working position in which the crown can be grasped with thumb and forefinger. For this purpose, a displacement part 17 is provided, which is inserted into the crown 13 and the rear part 19 of the elevator shaft 15, hereinafter also referred to as an extension of the elevator shaft 15, receives. The elevator shaft 15 may be made in one piece or in two parts consisting of the rear part or extension 19 and a front part 20. Extension 19 and front part 20 can, as shown in the exemplary embodiment, be screwed together (FIGS. 1 and 3).
    The extension 19 of the elevator shaft 15 has a cylindrical rear guide section 21 with a first diameter and a cylindrical front guide section 23 with a second diameter, wherein the second diameter is smaller than the first diameter. The sliding part 17 in turn has a front end 24 with a reduced inner diameter, which corresponds substantially to the second diameter of the front guide portion 23. Due to the reduced diameter of the front end 24, an annular shoulder 25 is formed. Between this and the step formed by the rear guide portion 27, a distance or displacement is defined, the sliding part 17 can be pulled relative to the elevator shaft 15 from the watch case, without the shaft is moved axially. The displacement is at least 1 mm, preferably at least 2 mm and more preferably at least 3 mm.
    The elevator shaft 15, respectively. the extension 19 has an axial bore 29, in which a compression spring 31 is received. The compression spring 31 is supported at one end in the interior of the elevator shaft 15 and at the other end on a closure part 33, which is placed on the rear end of the sliding part 17. On the closure member 33, a pin 35 is arranged or formed, which extends into the bore 29 and the compression spring 31 penetrates partially in the longitudinal direction. The diameter of the pin 35 is slightly smaller than the defined by the windings 37 of the compression spring 31 inner diameter. Thus, the pin 35 provides for axial alignment of the compression spring 31 also in the working position of the crown system, i. when the annular shoulder 25 bears against the step 27 and the compression spring 31 is partially located outside the bore 29. Thus, the compression spring 31 can be easily put on the pin 35, this is equipped with a tip 39. This ensures even when using the crown system that there is no unwanted collision or increased friction between the pin 35 and the windings 37 of the compression spring 31 when pushing in the crown.
    The sliding member 17 has at its rear end serving as a mounting portion collar 41, which has an annular shoulder 43 on the front side. The annular shoulder 43 serves as a seat for the disc or the closure part 33. The disc or the closure part 33 can be pressed, glued, soldered, welded or screwed to the collar 41. On the outer wall of the collar 41, an external thread 45 is provided for fastening the sliding part 17 on the crown thirteenth
    The crown 13 is formed as a one-sided closed hollow cylinder 47, in which adjacent to the bottom of an internal thread 49 is provided. With the internal thread 49, the displacement member 17 may be releasably connected to the crown 13. The solubility itself has no meaning for the function, but only affects the assembly. In addition, the crown 13 has a radially outwardly projecting edge 52, which lies in the rest position substantially within the periphery 71 (FIG. 4) of the watch case.
    Between the inner wall of the hollow cylinder 47 and the displacement part 17, an annular space 51 is present, which serves to receive a tube 53. In the tube 53 itself, the displacement part 17 is received axially displaceable. In this case, the length difference between displacement part 17 and tube 53 corresponds approximately to the displacement distance. As a result, the displacement part 17 is fully enclosed in each of the two possible extreme positions (resting and working position) by the tube inner wall 55. The tube 53 has a tapered attachment portion 57 for anchoring it firmly in an opening 58 of a watch case 69. At the Tubusinnenwandung 55 an annular groove 59 for receiving two O-rings 61 is provided. These watertight seal the interior of the housing against the environment. Following the opening 58, a bag-like recess 73 for receiving the crown head 13 is provided.
    To fix the crown in the rest position, an approximately V-shaped annular groove 63 is provided at the front end 24 of the sliding part 17. The annular groove 63 serves as a means of attacking a pawl spring 65, which is screwed by means of screws 67 on the watch case (Fig. 4). The pawl spring 65 engages in the rest position in the annular groove 63 and thereby holds the sliding member 17 in this position. However, if the sliding part is slightly pulled out of the watch case, pushes the spring 31, the crown 13 automatically in the working position.
    At the back of the watch case, a recess is provided below the crown 13 to the crown edge 52 can be taken with a fingertip.
    A crown system 11 with an elevator shaft 15 and arranged on the winding shaft 15 crown 13 is characterized in that on the winding shaft 15, a sliding member 17 is placed, in particular a sleeve. The elevator shaft 15 and the displacement member 17 relative to each other by a certain distance, respectively. a displacement telescopically axially displaceable in order to move the crown head 13 from a first housing near, axial displacement position, wholly or partially within the housing periphery, in a second housing remote, axial displacement position and vice versa. In this case, further axial, "housing distant" positions of the control shaft for controlling functions (date correction, pointer position, etc.) may be provided. Due to the additional displacement element, the shaft is extended by the displacement, so that the crown 13 can be accommodated in a watch case, without the movement would have to be changed. In one embodiment of the clock according to the invention, the spring element 31 brings the crown from the locked position into a first operating position. Other positions can be achieved "conventionally" by pulling the crown. Of importance is also that the spring force of the spring 31 is smaller than the resistance, which is constructed by the locking mechanism (spring latch 65, engaging means 63).
