    TECHNICAL FIELD [0001] The present invention relates to a watch telescopic crown assembly extending by a control rod passing through a housing and connected to an internal mechanism that it is likely to cause at least in rotation, during a manual action extraction on said ring, the latter being embedded in a housing of the housing and making it accessible only through extraction means.
    State of the art [0002] Indeed, it has been found that the crowns protruding from the housing were exposed to shocks and accidental maneuvers, hence the advantage of retracting them by embedding them in a housing housing.
    But a difficulty is created by the very fact of the embedding of the crown, which is poorly prehensed.
    The object of the invention is precisely to overcome this disadvantage in a simple and reliable manner.
    DESCRIPTION OF THE INVENTION [0005] For this purpose, it relates to a telescopic watch crown assembly, said watch comprising a housing provided with a housing and an internal mechanism, said telescopic ring assembly being arranged to pass through the housing. and being connected to the internal mechanism to be able to drive at least in rotation during a manual extraction action on said ring and comprises: a ring arranged to be embedded in the housing housing so as to make it accessible only by the intermediate extraction means, a control rod, said ring being provided with a barrel arranged to slide in the housing, said barrel comprising a bore inside which is housed the control rod, and an end of the barrel comprising an internal zone of shape capable of rotating a correspondingly shaped outer zone of said control rod, whatever the position axial relative ion of the crown, that is to say retracted or not, characterized in that the telescopic ring assembly comprises extraction means constituted by a switching member interposed between the control rod with which it is in axial connection with the crown on which a manual pressure can be exerted, in the manner of a push-button, for the passage from a retracted position (I) to an extraction position (III), or conversely, said switching part being constituted by a cylindrical element housed in the bore of the shaft of the ring, said switching part being free to rotate with respect to the control rod to which it is axially connected, and in that said extraction means are furthermore constituted by one or more balls interposed between one or more radial housings of said barrel and one or more parts of a ball path made on the external wall of the switching member so as to subjugate said committing part to the barrel, the portion or portions of the ball path having different portions of ramps leading to stable positions high (III) and low (I) of the ball in the portions of ramps respectively corresponding to the extraction of the crown from its housing housing or its retraction in the same housing.
    The ring is intended to be actuated in rotation in a main winding function, but may act on other functions by axial displacement relative to the housing.
    The present invention also relates to the features that will become apparent in the following description, and which should be considered in isolation or in all their possible technical combinations, within the scope of the claims.
    This description given by way of non-limiting example, will better understand how the invention can be made with reference to the accompanying drawings in which:
    Brief description of the figures [0009]
    Figs. 1, 2 and 3 represent, on an enlarged scale and in axial section, a set of watch winding crowns associated with retraction-extraction means, respectively in the position of retraction of the crown, during extraction and in extraction position, allowing its actuation in rotation, and vice versa, to return to the retracted position.
    Fig. 4 is a cross-sectional view of the assembly along line IV-IV of FIG. 1, before mounting on the housing, showing the connection of the ring with the switching part, and consequently with the control rod, said ring being in the retracted position.
    Fig. 5 is a cross-sectional view of the assembly along the line V-V of FIG. 1, showing the connection in permanent rotation of the end of the shaft of the crown with the control rod.
    Fig. 6 shows a perspective view of the switching part.
    Figs. 7 and 8 show front and side plan views of the switching part according to FIG. 6.
    Fig. 9 shows, on an enlarged scale, the developed part of the switching part, showing sy noptically the operating principle of the system in the retracted position or to an extraction position of the crown, or vice versa.
    DETAILED DESCRIPTION [0010] For ease of understanding of the description of the mechanism, the four subsets of the component have been distinguished by graying out or hatching them in different ways, without taking into account their own components and their particular arrangement. necessary for their assembly.
    It is: the hatched subset for the housing 4, incorporating the fixed tube 6 and the seal 9; the subassembly representing the at least rotary crew, composed of the ring 2 and extending by a shaft 10 whose end 11 is in permanent contact with a corresponding zone 13 of the control rod 3; the subassembly representing the control rod 3; of the hatched central sub-assembly representing the switching part 15 axially coupled to the aforementioned control rod 3, but free to rotate relative thereto.
    The figures show an assembly 1 of a telescopic watch crown extending by a control rod 3 passing through a housing 4 and connected to an internal mechanism (not shown) that it is capable of driving at least in rotation "R ", During a manual extraction action on said ring 2, the latter being embedded in a housing 5 of the housing 4 and making it accessible only through extraction means.
    The housing 4 is traversed by the control rod 3, through a fixed tube 6 housing, by its upper end 7, in a concentric inner recess 8 of the housing 4, through the seal 9.
    According to the present embodiment, the function obtained from the control rod 3 is only rotatable. But it could also be envisaged other functions after axial extraction of the ring 2, and therefore of the rod 3 which is integral with it, and which is in connection with the mechanism.
    Anyway, and according to the invention, the ring 2 is extended by a barrel 10 slidable in the housing 4, and within a bore of which is housed the control rod 3 , in this case the fixed tube 6, the end 11 of the barrel 10 having an internal zone 12 of shape able to drive in rotation a correspondingly shaped outer zone 13 of said control rod 3, whatever the axial relative position of the ring 2, that is to say retracted or not, the extraction means being constituted by a switching member 15 interposed between the control rod 3 with which it is in axial connection and the ring 2 on which is can be exerted a manual pressure FF, in the manner of a push button, for the passage from a retracted position I (Figure 1) to an extraction position III (Figure 3), or vice versa.
    More specifically, the switching part 15 is constituted by a cylindrical piece housed in an internal housing or bore 16 of the barrel 10 of the ring 2.
    The switching part 15 is free to rotate relative to the shaft 10 of the ring 2 and relative to the control rod 3 to which it is connected by an opening 21 of the rod 3 in which is housed freely a head 22 of the switching part 15.
    The switching part 15 is secured to the shaft 10 of the ring 2 by means of one or more balls, in this case two, "A" and "B" interposed between two radial housings 17, 18 diametrically opposed barrel 10 and a ball path "A", "B" made in two parts 19, 20 identical, made symmetrically on either side of a median plane "PD" of the outer wall of the piece of switching 15, which piece 15 is capable of being rotated on itself by said balls "A", "B" when moving axially under the thrust FF of the ring 2.
    As shown in the developed 23 of FIG. 9, the ball tracks 19, 20 respectively present different portions of ramps "a", "b", "c", "d", "e", "f" leading to stable positions high III and low I balls "A", "B" in the ramp portions "a", "b", "c", "d", "e", "f" respectively corresponding to the extraction of the ring 2 from its housing 5 housing 4 or its retraction in the same housing 5, to allow the drive in rotation of the ring 2, and consequently its mechanism (not shown) of the watch case 4 and its retraction then.
    In more detail, the parts 19,20 of the ball path are made on either side of a diametral plane "PD" in which the balls "A", "B" roll at the same time, according to the path and the following positions corresponding to a complete retraction-extraction-retraction cycle: retraction position I: the balls "A" and "B" are at the top of the lower portions of ramps "c";

    intermediate position II, from I to III: the balls "A", "B" are at the bottom of the portions of the ramps "d", after a first pressing on the ring 2 for the purpose of its extraction. The piece 15 then rotates on itself. - extraction position III of the ring 2: after releasing the pressure, the piece 15 is released and the balls "A", "B" back to the top of the ramp portions "f". intermediate position II, III to I: the balls "A", "B" are housed in the bottom of the ramp portions "d", after a second pressing on the ring 2, in view of a return to position d retraction; - Retraction position I of the ring 2: after releasing the pressure thereon, the balls "A", "B" back in the ramp portion "c" and the ring 2 returns to its original position. The operation of the system is as follows: the balls "A", "B" being housed in the openings 17, 18 of the shaft 10 of the ring 2, when they are in the low position, so retracted position 1 of the ring 2, and that is pressed a first time on the ring 2, said balls "A", "B" move in the ramp portion "d" of the switching part 15, which rotates on it even until the balls "A", "B" come to intermediate position II, at the bottom of the ramp portion "d". At this moment, by releasing the manual pressure FF on the ring gear 2 and thanks to a return spring 24, the balls "A", "B" are housed at the upper end of the ramp portion "a", therefore in the position d III extraction of the crown 2. [0022] It is recalled that the shaft 10 of the ring 2 is integral permanently in rotation with the control rod 3 by their respective shaped zones 12, 13, but free axial sliding. At this stage, one can turn the ring 2 for driving the control rod 3. The return to the retracted position is done by pressing a second time on the ring 2, always against the spring 24, which has the effect of pushing the balls "A", "B" to a new intermediate position II, the bottom of the ramp portion "b", then allow them, releasing the thrust FF, to go up upward of the ramp portion "c" corresponding to a new position I retraction. According to another characteristic of the invention, the ring 2 is retracted or removed from the housing 5 of the housing 4 by manual axial pressure FF on it, in the manner of a push button, s' performing against a return spring 24 interposed between the bottom 25 of an inner coaxial housing 26 of the switching part 15 and the bottom 27 of the bore 16 of the crown 2. Advantageously, the implementation resting the return spring 24 of the ring gear 2 on the bottom 27 of its bore 16 is effected by means of a pin 28 engaged in the spring 24 and whose friction end 29 on said bottom 27 is generally conical, in order to provide a reduced friction point contact. Furthermore, the axial connection between the switching member 15 and the control rod 3 is effected by means of a conical portion 30 of the head 22 of said switching member 15, supported on a zone plane 31 of the control rod 3, so as to provide a point contact with reduced friction. Optionally, the shaft 10 of the ring 2 comprises locking means in rotation, in a retracted position thereof. claims
