    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0010] The invention relates to a watch case 1, comprising a housing 2 in which is movable, at least in rotation, at least one control wheel 3 of a display or a function of the watch. This wheel 3 is arranged to be handled directly by the user of the watch at a peripheral contact surface 4. The denomination "box" is to be taken in the broad sense: this box 1 can naturally be a middle or the like .
    Figs. 1 and 2 show such a box 1, wherein the housing 2 is a groove groove, with, on either side of a bottom 20, an inner partition 21 and an outer partition 22. This outer partition 22 is interrupted between two edges 23 and 24, arranged to define an opening by which a user can operate a knob 3 inserted in the housing 2, as shown in FIG. 5.
    The geometry of the housing 2 allows the insertion, with the game, such a knob 3, and allows in particular that the wheel 3 can rotate and translate a small distance, for example and not limited in the direction 3 h-9 h on the box 1 illustrated by the figures, and with an opening so that the user of the watch can perform two movements: push the wheel 3 radially, and rotate it.
    According to the invention, this housing 2 is arranged to allow a limited translational movement, between an inner end of stroke and an outer end of stroke, of at least a portion 30 of the wheel 3 in a radial direction of the box 1, against elastic return means 5 which are arranged to move the part 30 from the inside of the box 1. It is understood that the part 30 is not always the same: it is only about of the portion of the wheel 3, which faces at a given instant at the opening, defined in the figures by the two edges 23 and 24.
    The figures illustrate a particular variant, wherein the housing 2 of the wheel 3 is in the immediate vicinity of the periphery of the box 1. Thus the wheel 3 surrounds a movement 100, without direct contact therewith.
    Other variants are feasible, in particular with a small wheel, which does not rotate around the watch, but which is substantially tangent internally at its periphery, only a portion 30 of the wheel 3 being, as before, accessible to the user. The housing 2 of this small wheel is also separated, in a sealed manner, the inner compartment of the box 1 which encloses the movement 100.
    The elastic return means 5 provide the repulsion function of the wheel 3 to the outside of the box 1 at rest, at the opening.
    To ensure the support detection function during the depression of the wheel 3, near the housing 2, the box 1 further comprises at least a first control detection means 7, which is arranged to detect the presence of the portion 30 of the wheel 3 closer to the center of the box 1 during a user-imposed support, and in particular at the end of internal race.
    In a particular and nonlimiting manner, and as shown in FIGS. 1 to 4, the box 1 can be provided with a pusher 54 constituting these elastic return means 5, which constrains the wheel 3 in an extreme position in the direction in which it can translate, in the 3 o'clock position in the particular case figures. More particularly, this pusher 54 comprises a head 53 in the form of a pad to facilitate the rotation of the wheel 3. On the inside of the box 1, this pusher 54, which passes through the inner partition 21, has a tail arranged to cooperate with a first control detection means 7. Because of its small dimensions, such a pusher 54 poses little problem of sealing. For a more demanding environment, such as a diving watch or the like, it may be advantageous to dissociate, on the one hand, the repulsion function of the wheel 3 towards the outside of the box 1 at rest, at the level of the opening , for example by a leaf spring or the like, and on the other hand the function of detecting the support during the driving of the wheel 3, by a strain gauge in the internal partition 21, an inductive sensor, the use of a deformable partition, or other.
    FIG. 3 shows the system at rest, the pusher 54 keeps the wheel 3 to the position at 3 o'clock.
    FIG. 4 shows the system when a user presses the wheel 3: his local area 30 translates from a position at 3 o'clock to the 9 o'clock position, the pusher 54 is pushed towards the inside of the box 1. example, this pressure is detected by an electronic module in the movement 100 of the watch 200.
    This first detection means 7 is arranged to activate or deactivate sensor means 8 that includes the box 1 near the housing 2, which sensor means 8 are arranged to detect, during a rotational movement printed by the user at the wheel 3, the passing transmitter means 9 that includes the wheel 3.
    More particularly, the sensor means 8 are kept remote from the emitter means 9, it is then a contactless interaction.
    In a particular variant, at least one of the sensor means 8 is arranged to detect the direction of passage or / and the reversal of the direction of passage of a transmitter means 9.
    In a particular variant, at least one of the sensor means 8 is arranged to detect the angular difference between two successive emitter means 9.
    In a particular variant, at least two of the sensor means 8 are arranged to detect the passage of the same transmitter means 9.
    In a particular variant, at least one of the sensor means 8 is arranged to measure the rotation angle of the wheel 3, traveled since a control detection performed by the first detection means 7.
    In a particular variant, at least one of the sensor means 8 is arranged to change position when passing a transmitter means 9 to its vicinity. More particularly, such a sensor means 8 constitutes a mechanical rocker, arranged to control a mechanical or electronic function of a clockwork movement 100 contained in the box 1. The mechanism according to the invention can thus, in a particular variant, to be completely mechanical. The combination of the mobile trip and stop components can also be sequential. For example, any movement of rotation of the wheel can trigger successively, on a chronograph mechanism, the start, stop, and reset.
    In an advantageous variant, the box 1 comprises control means 10, which are arranged to manage the signals transmitted and received at the first detection means 7 and the sensor means 8, to activate or deactivate these sensor means 8 , and for when the sensor means 8 are activated, analyzing the number of emitter means 9 identified by the sensor means 8, and / or the angular deviation of the emitter means 9 in pairs, and / or the direction of passage of the means transmitters 9, to transform the result of the analysis into a display order or activation of a function of the watch, addressed to a watch movement 100 contained in the box 1. More particularly, the detection means 7 and / or the sensor means 8 and / or the control means 10 are of the electronic type.
    In a particular embodiment, the wheel 3 is flexible and is itself the elastic return means 5. In this embodiment the housing 2 may consist of a groove of revolution, perfectly annular, and the pusher 54, arranged for the detecting the bearing pressure, advantageously plays the additional role of a tensioner of this flexible wheel 3, and locally gives the circular shape to this flexible wheel 3.
    In another particular variant, illustrated by the figures, the wheel 3 is rigid, and the elastic return means 5 comprise a pusher 54, which is arranged to bear on the wheel 3 by its head 53.
    In a particular variant, illustrated by the figures, the wheel 3 is annular, and the housing 2 is an oval having two half-rings connected by two straight sections, as shown in FIG. 11. In a variant, each half-ring is not strictly of revolution, but the outermost circle, leading to the opening, has an eccentricity, a little greater than the value of the offset between the two inner circles. , so that the wheel 3 protrudes from one side of the middle but not from the other.
    Other forms of housing are conceivable, for example substantially elliptical, or substantially annular, of variable width, and whose projection on any parallel to the radial direction of the box 1 is at least equal to the difference between the inside end of the race and the outer end of the race. Preferably, the housing 2 is shaped such that the game is as small as possible between the wheel 3 and the inner 21 and outer 22 walls, without causing excessive friction.
    In a particular variant, the first detection means 7 is a switch actuated by the elastic return means 5 or by a pusher 54 that comprise the elastic return means 5.
    In the variant illustrated by the figures, the wheel 3 is provided with magnets which constitute the emitter means 9, in particular but not limited to being arranged in a regular manner over its entire periphery, which allows the detection of the rotation of the wheel 3, via one or more sensors inside the middle part which constitute the sensor means 8.
    Thus, in a particular variant, the sensor means 8 are magnetic sensors, which are arranged to detect, once activated, the passage of magnets 91 that comprise the emitter means 9. More particularly, these magnets 91 are arranged at a constant angular pitch around the wheel 3. In another variant, these magnets 91 are arranged in different angular increments around the wheel 3.
    In a particular embodiment, the wheel 3 comprises, on a face arranged to cooperate with the bottom 20 of the housing 2, a relief 31 which is arranged to cooperate with a complementary relief 21 that comprises the bottom 20, for braking by notching when turning the knob 3.
    In a particular embodiment, the wheel 3 comprises, on a face arranged to cooperate with the bottom 20 of the housing 2, a relief 31 which is arranged to cooperate with a ring 39 in relief interposed between the wheel 3 and the bottom 20 , for a braking by detent during the rotation of the wheel 3. More particularly, this ring 39 in relief is an elastic ring. More particularly, this ring 39 in relief comprises at least one tab 38 of radial stop, arranged to cooperate in a complementary manner with a recess 28 of the housing 2.
    Thus we simply realize a notching system for the wheel, more enjoyable for the user than a simple friction. Such a ring 39 with a repetition of bumps and depressions is inserted into the housing 2 with the wheel 3, which is provided on its underside with at least one relief 31. FIGS. 9, 10, 13, 14, show two such reliefs 31 constituted by V-shaped lugs. Thus, when the wheel 3 rotates, each lug 31 vee jumps from one hollow of the ring to another.
    In a variant, the box 1 comprises a cover 19 or a bezel or a bottom, or an additional spacer, this component being arranged to enclose the wheel 3 in the box 1, as shown in FIG. 5.
    The principle of the invention is applicable to many variants, depending on the space available in the watch case, the thickness thereof, and the number of functions to be controlled.
    Thus fig. 17 illustrates a box 1 with two openings at 3 o'clock and 9 o'clock, with a pusher 54 facing each of these openings. Wheel 3 is accessible at 3 o'clock and 9 o'clock, and the presence of a pusher 54 on each side allows navigation in the menus: rotation detection activation at 3 o'clock and 9 o'clock, then "validation ok" at 3 o'clock and "return" at 9:00 am (or vice versa). Another box variant, illustrated in FIGS. 15 and 16, includes four non-detailed pushers (some of which may be without rotation detection) and a suitable geometry of the wheel to do without a part for vertical locking (no bezel or bottom ring).
    Yet another variant relates to a box with several wheels according to the invention, superimposed, each cooperating with a proper opening, FIG. 18 illustrates an example with two wheels 3X and 3Y, the box 1 having for example but not limited to two diametrically opposed openings, one for each wheel. The same housing 2 may contain several wheels 3, or each wheel 3 may have a separate housing 2.
    Fig. 19 illustrates a box variant comprising sensor means 8 housed in a horn 18, cooperating with the peripheral surface 4 of the wheel 3, either by mechanical friction contact or direct drive if for example this peripheral surface 4 is fluted or the like either by magnetic interaction, or other.
    FIG. 20 illustrates a variant where the pusher comprises, in place of a shoe, a pinion 57 cooperating with a toothing 37 which then comprises the wheel 3, or which is attached to the wheel, the push rod then allows the detection of the translation and rotation.
    The invention also relates to a watch 200 comprising such a box 1, arranged to enclose a watch movement 100, whose display or watch functions are arranged to be controlled by sensor means 8 of the box 1.
    The mechanism according to the invention has different advantages.
    First of all, this system is without risk for the sealing of the watch, the areas to be sealed concerning known and controlled systems, such as ice / box and push / box connections. The sensor that detects the pressure is mounted on the movement and is activated by the pusher which is easy to seal. Sensors that detect rotation are on the move. As magnetic sensing is non-contact, there is no sealing problem.
    In principle the repulsion function of the wheel can be provided by a pusher that does not open on the inside of the box or the middle part. In particular in the variants illustrated, an appropriate dimensioning of the notch, the force and the position of the magnets, and the position of the magnetic sensors, allows the detection of the translation and the rotation of the wheel. Other other non-contact solutions, in particular galvanic or optical, are feasible, but of less economic realization. The use of a deformable partition, for a watch plastic box in particular, allows a detection of the translation without contact.

    Another advantage of the invention is, in the preferred but nonlimiting variant of magnetic detection, the possibility of using the watch under water or in a humid environment. The area available for the finger of the user can actuate the wheel is extended, which allows a good resolution of the detection: in the case of an electronic watch or a smart or connected watch, the user does not have to make many laps to scroll through the menus (compared to an electronic crown for example). This advantage comes from the fact that the wheel is all around the movement. The notching system allows a good feeling for the user to determine how many steps it advances. claims
