    According to the invention, this display mechanism 1 comprises at least one axial stop 7, which is arranged to limit to a predetermined value the axial clearance in the direction of the main axis DP between the center tube 2 and the mobile display 6 or 8. And this at least one axial abutment 7 is, or a protruding surface 28, 69, the center tube 2 or the mobile display 6, 8, or an axial abutment reported 71 79, 76, 98 which is either mounted between the center tube 2 and the display unit 6, 8 or is fixed to the display unit 6, 8.
    Figs. 2 and 5 illustrate a first embodiment where the axial abutment comprises an attached ring, fixed on the center tube 2 or on a mobile that guides this center tube 2.
    FIG. 2 illustrates a variant of the invention in which the display mobile is an inner mobile 6, guided in the main bore 4 of the center tube 2. The axial abutment 7 is here an axial abutment reported having a first ring 71 driven on a first bearing surface 66 of the inner mobile unit 6, resting on a first shoulder 67 which this internal mobile device 6 comprises, at one end of the first bearing surface 66. This first ring 71 comprises, facing the plate 3, a first abutment face 74 which is arranged to constitute an abutment with respect to a first upper face 24 that includes the center tube 2. The inner mobile 6 comprises, on the opposite side to the first bearing 66 relative to the plate 3, a first end face 63 which is opposed to a first lower face 23 that includes the center tube 2. In particular, the first upper face 24 and / or the first lower face 23 is perpendicular to the DP main axis. In particular, the first shoulder 67 or / and the first end face 63 is perpendicular to the main axis DP. In particular, the first abutment face 74 is perpendicular to the main axis DP.
    The relative movement of the inner rotor 6 relative to the center tube 2 is thus limited to the upper level by a stop abutment engagement between the first abutment face 74 and the first upper face 24, and, at the opposite lower level at the upper level, by cooperation in abutment support between the first end face 63 and the first lower face 23.
    FIG. 5 illustrates a variant of the invention, similar to that of FIG. 2, but where the mobile display is an outer mobile 8, guided on a main scope 5 of the center tube 2. The axial stop 7 is an axial abutment reported having a second ring 79 driven on a second bearing 29 of the tube center 2, bearing on a second shoulder 27 that includes the center tube 2, at one end of the second bearing 29. This second ring 79 comprises, facing the plate 3, a second abutment face 78 which is arranged to constitute an abutment with respect to a second upper face 88 that the external mobile device 8 comprises. The outer mobile device 8 comprises, on the side opposite the second upper face 88 and as close as possible to the plate 3, a second end face 86, which is opposed to an intermediate face 26 that includes the center tube 2. The relative movement of the outer mobile 8 relative to the center tube 2 is limited to the upper level by a cooperation abutment abutment between the second stop face 78 and the second upper face 88, and, at an intermediate level between the plate 3 and the upper level, by a stop-abutment engagement between the second end face 86 and the intermediate face 26.
    More particularly, the inner mobile 6 is a second wheel in the center, the axial Z-shaped holding is ensured by a ring driven on the shaft from the needle side.
    In a variant where it is not envisaged disassembly, the insert ring can be driven, glued, welded, riveted, crimped, or the like.
    Figs. 6 and 7 illustrate a second embodiment where the axial abutment has a protruding surface at the level of the center tube 2 or a mobile that guides this center tube 2.
    FIG. 6 illustrates a configuration where the mobile display is still an inner mobile 6 guided in the main bore 4 of the center tube 2. The axial stop 7 this time comprises a first protruding surface 69, which comprises the inner mobile 6, and which defines, facing the plate 3, a first abutment surface 68, which is arranged to form a stop relative to the first upper face 24 of the center tube 2.
    This protruding surface may be made by deformation of the shaft of the inner mobile 6, or by material supply, or by a local deformation created by a removal of material. Without limitation, it is possible to locally push the material of the inner movable shaft 6, to form a bead, or to pre-machine this shaft with a folding lip with a rivet, or to machine, after assembly of the shaft of the inner mobile 6 already threaded into the center tube 2 and lower support, peripheral craters with a laser beam just above the end face of the center tube 2, or to perform a simple bleed of revolution, one of the lips forms the stop, or to perform a plasma projection, or welding a point or a series of points or a cord, or other.
    As for the variant of FIG. 2, the inner mobile device 6 comprises, on the opposite side to the first bearing surface 66 with respect to the plate 3, a first end face 63 opposite to the first lower face 23 that comprises the center tube 2. And the relative movement of the mobile 6 inside relative to the center tube 2 is limited to the upper level by a stop abutment cooperation between the first abutment surface 68 and the first upper face 24, and, at the lower level opposite said upper level, by a bearing cooperation stop between the first end face 63 and the first lower face 23.
    FIG. 7 illustrates a variant of the invention, similar to that of FIG. 6, but where the mobile display is still an outer mobile 8, guided on a main surface 5 of the center tube 2. The axial abutment 7 is a second protruding surface 28, which comprises the center tube 2, and which comprises , facing the plate 3, a second abutment surface 280 arranged to form a stop relative to a second upper face 88 that includes the outer mobile 8. This second protruding surface 28 may be made analogously to the first protruding surface 69 of fig. 6. The outer mobile 8 comprises, on the opposite side to the second upper face 88 and closest to the plate 3, a second end face 86 opposite the intermediate face 26 of the center tube 2. The relative movement of the mobile 8 outside relative to the center tube 2 is limited to the upper level by a thrust bearing cooperation between the second abutment surface 280 and the second upper face 88, and at an intermediate level between the plate 3 and the upper level by a stop abutment engagement between the second end face 86 and the intermediate face 26.
    Figs. 3 and 4 illustrate a third embodiment where the axial stop 7 comprises at least one intermediate component, which is mounted prisoner between the center tube 2 and the mobile 6, 8, which guides the center tube 2.
    More particularly according to the invention, this intermediate component is an elastic component, such as circlips or the like. More particularly still, the axial abutment 7 is an axial abutment with a circlip 76, 98, housed both in an external groove 21, 22, which comprises the center tube 2 and in an internal groove 61, 82, which comprises the mobile 6, 8.
    FIG. 3 illustrates a variant where the mobile display is an inner mobile 6 guided in the main bore 4 of the center tube 2. The reported axial abutment is here a first circlip 76, housed in both a first external groove 21 that comprises the central tube 2, and in a first internal groove 61 that includes the inner mobile 6. The relative movement of the inner mobile 6 relative to the center tube 2 is limited by a cooperation in abutment abutment between the first circlip 76 d firstly, and first internal groove side surfaces 211,212 of the first external groove 21 and first lateral surfaces of external grooves 611,612 of the first internal groove 61 on the other hand.
    FIG. 4 illustrates a variant where the mobile display is an outer mobile 8 guided on the main scope 5 of the center tube 2. The reported axial abutment 7 is here a second circlip 98 housed at a time in a second outer groove 22 that includes the center tube 2, and in a second internal groove 82 that comprises the outer mobile 8. The relative movement of the outer mobile 8 relative to the center tube 2 is limited by a cooperation abutment between the second circlip 98 of one side, and second lateral surfaces of inner grooves 221, 222 of the second outer groove 22 and the second lateral surfaces of outer grooves 821, 822 of the second inner groove 82 on the other hand.
    More particularly, the inner mobile 6 is a second wheel in the center, the Z axial holding is thus provided by a circlip pre-mounted on the center tube, the second wheel is then clipped on the circlip by its internal groove when pushing the wheel Z second wheel against the center tube 2, as shown in Figs. 11 to 16 exposed later.
    In a particular embodiment of the first embodiment, and with regard only to the inner mobile 6 illustrated in FIG. 2, and as visible in FIGS. 8 to 10, the first ring 71 is constituted by the barrel 710 of a needle 70 fitted on the inner mobile 6, supported by a gun end surface 702 that includes the barrel 710, on the first upper face 24 of the tube 2. More particularly, this barrel 710 comprises elastic lips 703 whose end constitutes the barrel end surface 702, and which are arranged to allow the clipping of an inner bead 701 that includes this barrel 710 on a groove. 60 device that includes the shaft of the inner mobile 6, determining the exact position of maintaining axial abutment.
    In another variant, the needle 71 is driven on a first bearing 66 of the shaft of the inner mobile 6 abutting abutment on a first shoulder 67 that includes the inner mobile 6, at one end of the first range 66. More particularly, this inner mobile 6 is a second mobile in the center. In this variant, it is the barrel 710 of the needle which abuts on the first upper face 24 of the center tube 2. It therefore controls the stroke rating, and therefore the position of the stop because the needle is driven against a shoulder.
    Figs. 17 to 23 illustrate another variant, with the mounting of three concentric wheels with the board which acts as circlips, thus removing the bottom side bridge and the deck side dial. The tubes and center pins are mounted with their board riveted, then during the vertical insertion the mobiles are clipped in position. Everything then forms an indémontable whole.
    More specifically, the inner mobile 6, more particularly carrying the seconds shaft, comprises a wheel having a marking opening 603, which also defines an arm 602 carrying a flexible tongue 601 arranged to cooperate by clipping with a lower groove 206 that includes the center tube 2, for its axial stop, as shown in FIGS. 18, 19 and 20.
    The outer mobile 8, more particularly the minute wheel, has a similar arrangement, and comprises a wheel having a marking opening 803, which also defines an arm 802 carrying a flexible tongue 801 arranged to cooperate by clipping with a middle groove 208 that includes the center tube 2, for its axial stop, as visible in FIGS. 18, 20 and 21.
    An upper mobile 80, more particularly the hour wheel, similar to FIGS. 2 and 3, comprises a similar arrangement, and comprises a wheel having a marking opening 8003, which also delimits an arm 8002 carrying a flexible tongue 8001 arranged to cooperate by clipping with an upper groove 8000 that comprises the outer mobile 8, for its axial stop, as visible in FIGS. 18, 22 and 23.
    Figs. 17 to 23 illustrate yet another variant, with the assembly of three concentric wheels, in a mixed solution with both axial stops by axial thrust 71 and by circlips. Here too, we can remove the bottom side bridge and the dial side bridge.
    More specifically, in yet another variant, shown in FIGS. 24 to 31, the shaft of the inner rotor 6, more particularly a seconds shaft, is stopped on the end of the center tube 2 by an axial abutment 71, as shown in FIGS. 24 to 26.
    The outer mobile 8, more particularly carrying the floor minutes, has two slots 880 for locking the mobile axially with a circlip 980, above which the outer mobile 8 has a stop groove 883.
    The upper mobile 80, more particularly carrying the hour floor, similar to FIGS. 2 and 3, comprises a wheel having a locating opening, and comprises a large circlip 881 already pre-mounted on the wheel, a maximum diameter slightly smaller than that of this wheel, and stopped by a shoulder of the roadway 882, and, during the axial insertion, the wheel closes in position in the stop groove 883.
    The circlip 881 also has a cutout, which also allows to raise the level of the capacitive opening (0.15 mm) on the nearest board. The latter also makes it possible to gain counter-weight on the mobile time and thus to mount a maximized unbalanced hour hand.
