Definitions

  • the present invention relates to a watch provided with a device for locking a control member that can be actuated by a user of the watch, in particular a pusher associated with a chronograph mechanism.
  • the patent application JP 2005-337792 describes a watch fitted with a chronograph mechanism, associated with two push-pieces which can be actuated in a conventional manner by a user from outside the case, and with a device for locking these two push-pieces which comprises a locking ring arranged in a groove top of the caseband of the watch so as to form a bezel surrounding the display area defined by the dial of the watch.
  • the groove has at least one lateral opening to allow the gripping of the locking ring and its actuation in rotation, so as to be able to drive the locking ring between at least one angular locking position and at least one angular unlocking position .
  • the locking ring has distinct lower parts which extend over a plurality of angular sectors, leaving between them empty sectors, that is to say without material.
  • one of the lower parts is located in a groove of the control or behind an inner lateral surface of this control member, so as to block, respectively stop a translational movement in a corresponding radial direction and thus prevent activation of a corresponding function.
  • the control member is then located angularly opposite an empty sector, so that this control member is free to move in the corresponding radial direction and its actuation in translation in this radial direction is then possible to activate the corresponding function.
  • the locking ring forms a bezel of the watch and no other rotating bezel, in particular associated with the chronograph mechanism, is provided. Note that the arrangement of the locking ring is such that it actually prevents the watch from being fitted with another rotating bezel which can be associated with a function other than the locking of at least one of the order this watch.
  • two lateral openings are provided in the middle part to allow a gripping of the locking ring by a user and its rotational actuation. These two openings are unsightly and give a complex shape to the case, which increases its manufacturing cost.
  • the two lateral openings of the case middle are opposed to a harmonious shape of the case in its upper part, the case presenting a kind of step on its two lateral sides, and in addition this realization exposes, in a top view, control devices.
  • the object of the present invention is to provide a watch of the type described above with a device for locking at least one external control member, the arrangement of which is discreet, while allowing a user to operate it easily.
  • the invention aims to providing such a watch with a case provided with a rotating bezel which is associated with a function of the watch other than the locking described above.
  • the subject of the present invention is a watch comprising a watch movement and a case incorporating this watch movement and provided with a control member making it possible to activate a function of the watch movement, this control member being movable in a radial direction and operable by a user from outside the housing, this housing being further provided with a device for locking the control member.
  • the locking device comprises a locking member which is rotatably mounted around a central axis of the case and which is arranged so as to be able to be actuated by the user of the watch between at least one angular locking position, in which the control member is stopped or blocked by the locking device so that said function cannot be activated by actuation of this control member in said radial direction, and at least one angular unlocking position in which the control member is released and can be actuated in said radial direction so as to allow activation of said function.
  • the watch further comprises a rotating bezel around said central axis, this rotating bezel and the locking member thus being coaxial.
  • the rotating bezel and the locking member form two separate members and are arranged so that they can each be actuated in rotation, by a user, independently of the other.
  • the locking member comprises an annular part, centered on said central axis, which is arranged between the rotating bezel and a middle part supporting this rotating bezel.
  • the locking device does not take the place of a rotating bezel conventionally associated with the chronograph mechanism.
  • the device lock is, in the preferred variant, particularly discreet and not very visible from the top of the watch.
  • the rotating bezel is associated with the chronograph mechanism.
  • the watch is provided for diving.
  • the locking member comprises a gripping element secured to its annular part and located outside the middle of the case so as to allow it to be gripped by a user, in order to be able to easily rotate the locking member at least between the angular locking position and the angular unlocking position, and this obviously in both directions.
  • the control member is either a stem-crown allowing in particular a time setting of the watch, or a pusher associated with at least one function of the watch.
  • the locking device can be used to lock only one of the two push-pieces, in particular the one serving to engage and then end the measurement of a time interval (a time), or both buttons, simultaneously or separately.
  • the locking device can be arranged so as to make it possible to lock, depending on the angular position of the locking member, only the first pusher, only the second pusher and the two pushers.
  • the locking device can even be used to lock the stem-crown, in particular in its winding position (that is to say not pulled out) in addition to that of at least one of the two pushers when the locking member is in a certain angular position.
  • the locking device can be used to lock the valve in a screwed closed position, at least when the locking member is in a specific angular position .
  • the locking device comprises a locking member which is rotatably mounted around a central axis of the case and which is arranged so as to be able to be actuated by the user of the watch between at least one angular locking position, in which the valve is blocked by the locking in a screwed closed position, and at least one angular unlocking position in which the valve is released and can be unscrewed and actuated in said radial direction so as to allow its opening.
  • the locking device can also be used to lock a control member, as mentioned above, when the locking member is in said specific angular position or in at least one other angular position.
  • the locking member comprises a lower part, in particular formed of several annular sectors separated by empty zones, which is integral with the annular part or formed by the latter, this lower part being extending globally in an angular zone less than 360° and forming an abutment for a part of the valve movable in radial translation, this lower part being configured so as to block the valve, in said radial direction, in said screwed closing position, and thus preventing this valve from opening when the locking member is in said angular locking position and leaving the valve free in its mobility in said radial direction when the locking member is in said angular unlocking position.
  • Watch 2 is, in the variant represented, a diver's watch.
  • the watch 2 comprises a watch movement 4 and a case 6 which incorporates this watch movement, which comprises a chronograph mechanism.
  • the case 6 is provided with several control members, namely two pushers 8, 9 and a stem-crown 10, which make it possible respectively to activate different functions of the watch movement.
  • the case is provided with a valve 7 because the watch shown is a diver's watch.
  • the valve and each of the control members is movable in a radial direction, 12 and 13 respectively for the pushers 8 and 9, and can be actuated by a user from outside the housing.
  • valve 7 is screwed into its closed position.
  • we will consider more particularly the pusher 8 which is conventionally used for the 'chrono' function of the chronograph mechanism, more precisely to start the measurement of a time interval and then to put an end to this measurement.
  • the housing 6 is provided with a locking device 14 provided to be able to lock at least for the pusher 8.
  • This locking device comprises a locking member 16 which is rotatably mounted around a central axis 18 of the housing and which is arranged so as to be able to be actuated by the user of the watch between at least one angular locking position a1 (state shown in Fig. 1 ), in which the pusher 8 is stopped or blocked by the locking device so that its function cannot be activated by actuation of this control member in the radial direction mentioned, and at least one angular unlocking position ⁇ 2 ( state shown in Fig.
  • the watch further comprises a rotating bezel 20 around the central axis 18, this rotating bezel and the locking member 16 thus being coaxial.
  • the rotating bezel and the locking member are arranged so that they can each be actuated in rotation by the user independently of the other, that is to say be actuated in rotation independently of one another. the other.
  • the rotating bezel 20 is associated with a useful function for diving.
  • the locking member 16 comprises an annular part 22, centered on the central axis 18, which is arranged between the rotating bezel 20 and the middle part 40 of the case 6, more generally between the rotating bezel and a radial rod 24 of the pusher 8.
  • This arrangement makes it possible to incorporate the locking member 16 for the most part inside the case 6, in particular the entirety of said annular part, thus allowing the locking device to be discreet and not very visible from above the watch, that is to say from the side of the analog display device.
  • the rotating bezel 20 comprises internal toothing 26 conventionally associated with a pawl spring 28 for the angular positioning of this rotating bezel.
  • the internal toothing 26 is located in a cylindrical space inside the locking member 16, in particular its annular part 22.
  • the internal toothing is located substantially at the same level than the locking member 16, which makes it possible to obtain a housing whose height is not or only slightly increased by the incorporation of the locking device.
  • the concentric arrangement of the annular part 22 and of the device for angular positioning of the rotating bezel 20 makes it possible to reduce the size of the locking device.
  • annular spacer 30 is arranged in an annular cavity defined by the rotating bezel and the annular part of the locking member, between them.
  • This annular spacer has at least one sliding surface in contact with a lower surface 32 of the rotating bezel or with an upper surface 34 of the annular part, this sliding surface having a low coefficient of friction with this lower surface, respectively this surface superior.
  • the spacer 30 is mounted free to rotate, that is to say it is not fixed to the annular part or to the lower part of the rotating bezel.
  • the spacer has a lower sliding surface in contact with the upper surface 34 and an upper sliding surface in contact with the lower surface 32.
  • the spacer 30 is formed by polyoxymethylene (POM), in particular Delrin ® .
  • the coefficient of friction is located approximately in the range of values 0.20-0.35.
  • the locking member 16 comprises a gripping element 36 which is integral with the annular part 22 and is located outside the middle part 40 of the case so as to allow it to be easily gripped by a user, in order to be able to rotate the locking member between the angular locking position ⁇ 1 and the angular unlocking position ⁇ 2.
  • This gripping element is elegant and gives an additional technical character to the diving chronograph watch. It will be noted that in the variant shown in the figures, the annular part 22 of the locking member has a cylindrical side face which is laterally visible over its entire periphery.
  • the annular part in another variant, it is possible to provide for the annular part to be located entirely inside the casing and therefore not visible from the outside, except possibly at the two ends of an angular zone traversed by a connecting part between the gripping element and the annular part.
  • the gripping element 36 is advantageously located in an angular sector between 220° and 290°, calculated clockwise from the '12 o'clock position, corresponding to 0°, on a '12 o'clock hour rotation.
