CLOCK CASE WITH A CORRECTION ORGAN

Description

Technical field of the invention

[0001] The invention relates to a case for a timepiece, for example a wristwatch, comprising a multifunction correction member making it possible, for example, to select and / or modify information displayed on a dial by means of a single control member.

[0002] The invention also relates to a timepiece comprising such a case and such a multifunction correction member for selecting and / or modifying information displayed on a dial, for example for correcting, activating, or resetting several functions derived from the current time. Technological background

[0003] A timepiece, particularly a wristwatch, allows the user to know the current time. This current time can be corrected by exerting an action (for example, traction) on the winding stem until a specific position is obtained for this correction action.

[0004] The wristwatch can also display, correct, activate, reset functions derived from the current time, generally called complications, such as a date, a time zone, a chronograph, etc.

[0005] To achieve this, it is necessary to incorporate correction organs into the case of the wristwatch to control and / or correct these additional functions.

[0006] These correction organs generally comprise a push-type control organ positioned outside the case middle of the watch case and which cooperates with a movable control stem in an orifice passing radially through the case middle. Such correction organs make it possible to control and / or correct the ancillary functions without the use of a tool by the user.

[0007] Certain timepieces, and in particular watches, with several complications, offer their users a large number of functions requiring the multiplication of these correction organs on the case, as in documents CH706888A2 and EP1939699A1 for example.

[0008] However, the multiplication of correction organs at the caseband level poses installation problems and can cause aesthetic issues, particularly for mid-range and high-end timepieces, where a sober and elegant aesthetic is sought.

[0009] The multiplication of correction organs at the caseband level also creates watertightness problems due to the multiplication of openings in the watch case that must be made for the integration and assembly of the various correction organs. Summary of the invention

[0010] In this context, the invention aims to propose a solution to the drawbacks of the state of the art specified above, by proposing in particular a timepiece case comprising a correction member making it possible to select, activate and / or modify at least two different functions, with the same correction member requiring only a single opening in the case middle for its assembly.

[0011] To this end, the subject of the invention is a timepiece case comprising a caseband delimiting an internal space capable of receiving a timepiece movement having at least one function corrector for performing different functions of activation, selection, resetting and / or correction of information derived from the current time of said timepiece movement, the caseband having a through-hole configured to receive a correction member capable of interacting with at least one function corrector of said timepiece movement, said correction member comprising: a cylindrical body of longitudinal axis XX, a control stem movable in translation inside said cylindrical body, along the longitudinal axis XX, said control stem comprising an end intended to cooperate with at least one function corrector of said timepiece movement,a pusher secured to said control stem and accessible by the user from outside said case, characterized in that the correction member is mounted to slide in said slot in the caseband substantially or essentially transversely relative to the longitudinal axis (XX) between several stable positions, each of the stable positions modifying the position of the end of said control stem opposite said watch movement.,

[0012] Thus, the user can easily select at least one function corrector of said watch movement that he wishes to activate, and operate it when pressure is exerted on the pusher.

[0013] Thus, the case and the correction organ according to the invention propose an innovative solution to minimize the number of openings to be made in the case middle of the watch case. Thus, the problem of sealing and installation is overcome by reducing the number of corrective devices to be installed in the case middle.

[0014] It will be noted that the multifunction correction member according to the invention is a correction device different from an adjustment crown linked to the winding stem which allows a function of adjusting the time, and possibly winding the barrel. Thus, the multifunction correction member according to the invention is not connected to a winding stem, for winding a barrel, and does not allow the current time of the movement to be adjusted.

[0015] In addition to the characteristics mentioned in the preceding paragraph, the timepiece case according to the invention may have one or more additional characteristics among the following, considered individually or according to all technically possible combinations: for one of the stable positions of the correction member, the end of said control stem is able to be positioned opposite a function corrector of the timepiece movement, so that the correction member is able to execute a function associated with the function corrector when pressure is exerted on the push-button; for one of the stable positions of the correction member, the end of said control stem is able to be positioned opposite a plurality of function correctors of the timepiece movement, so that the correction member is able to simultaneously execute a combination of functions associated with the function correctors when pressure is exerted on the push-button; for one of the stable positions of the correction member, the end of said control stem is configured to be inactive with respect to the timepiece movement when pressure is exerted on the push-button;the timepiece movement comprises a first function corrector and a second function corrector, and in a first stable position of the correction member, the end of said control stem is able to be positioned opposite the first function corrector and in a second stable position of the correction member, said end of said control stem is able to be positioned opposite the second function corrector; the light is configured to allow rectilinear sliding mounting of the correction member in the caseband; the light is configured to allow curvilinear sliding mounting of the correction member in the caseband; the cylindrical body cooperates with a mounting ring movable in the light and configured to secure the correction member to said caseband; the light forms a slide and in that the mounting ring forms a slide movable in the light;the light is oblong in shape and in that the mounting ring is of complementary shape to slide in said light; said mounting ring comprises a collar configured to cooperate with a counterbore provided at an inner face that the caseband comprises; said cylindrical body is secured to the mounting ring by screwing or driving; the cylindrical body has the shape of a cylinder of revolution with an axis of revolution XX and in that the control rod is coaxial with the cylindrical body; the correction member comprises a return element configured to ensure the return of the pusher to a stable rest position; the case comprises an indexing member for indexing the plurality of stable positions of the correction member; the indexing member is formed by a plurality of ball indexers carried by the caseband; the indexing member is formed by a plurality of ball indexers provided in bores that the caseband comprises;the ball indexers cooperate with recesses provided on the mounting ring;

[0016] The invention also relates to a timepiece comprising a case according to the invention, a timepiece movement housed in said case, the timepiece movement carrying and driving means for displaying the current time and comprising at least one function corrector making it possible in particular to activate, select, reset or correct at least one item of information derived from the current time of said timepiece movement.

[0017] Advantageously, the clockwork movement comprises a first function corrector and a second function corrector.

[0018] Advantageously, the first function corrector and the second function corrector are formed by superimposed pivoting rockers.

[0019] Advantageously, the timepiece is a wristwatch.

[0020] Advantageously, the movement of the timepiece is a mechanical movement. Brief description of the figures

[0022] In all figures, common elements bear the same reference numbers unless otherwise specified. Detailed description of the invention

[0023] The correction organ according to the invention is a multifunction correction organ making it possible to select and / or activate function correctors that a watch movement comprises to carry out different functions of activation, selection, resetting and / or correction of information derived from the current time, by means of a single control organ accessible by the user from outside the case.

[0024] The correction organ thus forms a user interface for controlling different functions associated with information derived from the current time contained in a clock movement housed in a case.

[0025] There figure 1 schematically represents a top view of an exemplary embodiment of a timepiece case 2 comprising a correction member 100 according to the invention.

[0026] In reference to the figure 1, the case 20 is illustrated in transparency in order to be able to visualize the correction member 100 as a whole.

[0027] The correction member 100 extends along a longitudinal axis XX.

[0028] As visible at the figure 1 , the correction member 100 according to the invention is a correction member different from an adjustment crown 3 linked to the winding stem (not shown) which allows a function of adjusting the current time, and possibly of winding the barrel. In other words, the correction member 100 according to the invention is not connected to a winding stem and does not allow the adjustment of the current time of the movement.

[0029] The watch case 2 is, for example, a wristwatch case.

[0030] The box 2 conventionally comprises a base (not shown), a side wall forming a middle 20 and a glass (not shown) closing the box.

[0031] The box 2 shown is circular in shape, but the invention is also applicable to other shapes of box usually used in the field of watchmaking.

[0032] The case 20 has an outer face 23 and an inner face 24. The inner face 24 of the case 24 delimits an internal space intended to receive a clockwork movement 1 (not shown as a whole).

[0033] The clockwork movement 1 carries and drives means for displaying the current time and in particular comprises at least one complication making it possible to display at least one piece of information derived from the current time. For this purpose, the clockwork movement 1 comprises a plurality of function correctors 10, 12. making it possible to display, correct, select, engage, and / or reset at least one piece of information derived from the current time.

[0034] In the illustrated embodiment, the clockwork movement 1 comprises a first function corrector 10 and a second function corrector 12 for displaying, correcting, selecting, activating, or resetting at least one function derived from the current time. However, this representation is not limiting.

[0035] For example, the clock movement 1 may include a complication such as a date, time zone, chronograph, etc.

[0036] The function correctors 10, 12 are for example superimposed rockers mounted to pivot around a pivot axis 11, as illustrated in particular in figure 1 . However, other types of function correctors are being considered.

[0037] There figure 2 represents a view of the outer face 23 of the caseband 20, in particular at the level of the location of the correction member 100.

[0038] Figure 6 represents a view of the inner face 24 of the middle part 20, in particular at the level of the location of the correction member 100.

[0039] As is visible in particular in figures 1, 2 and 6, the middle part 20 has a through light 21, having a radial orientation, that is to say extending from the outer face 23 to the inner face 24, and configured to receive and carry the correction member 100 according to the invention.

[0040] The light 21 forms a slide and is configured to allow sliding mounting of the correction member 100, so that it is movable in the caseband 20.

[0041] The light 21 allows a back-and-forth movement of the correction member 100 in the caseband 20, thus making it possible to move and modify the positioning of the correction member 100 in the caseband 20, and with respect to the watch movement 1. Thus, it is possible to position the correction member 100 in different stable activation positions making it possible to position the correction member opposite one or more function correctors that the watch movement 1 comprises or even in a neutral position making it possible to position the correction member opposite no function corrector that the watch movement 1 comprises, to ensure that no function of the movement will be activated inadvertently in the event of pressure on the correction member 100.

[0042] The light 21 can have different shapes depending on the number of positions of the correction member 100 that one wishes to achieve, the integration needs of the different parts, the shape of the box 2, etc.

[0043] Of course, it is clear that the back-and-forth movement permitted by the light 21 is different from the movement inherent in the operation of the correction member 100 whose pusher moves radially relative to the caseband 20, that is to say along the longitudinal axis XX of the cylindrical body 110.

[0044] For example, the light 21 is oblong in shape. However, other shapes are possible since the light 21 forms a slide and allows sliding mounting of the correction member 100 and modification of the relative position of the correction member 100 with respect to the watch movement by sliding in the caseband 20.

[0045] The light 21 has at the level of the inner face 24 a counterbore 26 of oblong shape (visible more particularly in figure 6).

[0046] There figure 3 is a more detailed representation of the correction member 100 according to the invention, and the figure 4 is a sagittal section, along the AA axis illustrated in figure 3 . It should be noted that on the figure 3 , the case 20 is not shown in order to better visualize the correction organ 100 and its interaction with the function correctors 10, 12 of the clockwork movement 1.

[0047] The correction member 100 according to the invention is of the push button type.

[0048] The correction member 100 comprises a cylindrical body 110 cooperating with a movable mounting ring 180 forming a slide capable of sliding in the slot 21. The assembly of the two elements makes it possible to secure the correction member 100 to the caseband 20 and to produce a sliding mounting of the correction member 100 at the slot 21 of the caseband 20.

[0049] In the illustrated embodiment, the cylindrical body 110 is a cylinder of revolution with axis of revolution XX, having a circular section.

[0050] The cylindrical body 110 comprises a tubular portion 111 and a head 112, the head 112 forming a first end of the cylindrical body 110.

[0051] The tubular part 111 may have a threaded portion for its assembly by screwing to the mounting ring 180. The mounting ring 180 comprises a collar 182 intended to come into contact with the counterbore 26 of the slot 21 of the middle part 20.

[0052] For this purpose, the mounting ring 180 has an external shape configured to be able to slide freely in a lateral back-and-forth movement in the lumen 21, between at least two positions.

[0053] In the illustrated embodiment, the mounting ring 180 is cylindrical in shape with an oblong section having an internal circular bore 181. The internal circular bore 181 has a threaded portion for receiving the tubular part 111 of the cylindrical body 110 and for allowing the assembly of the two elements by screwing, as well as the mounting of the correction member 100 at the level of the middle 20.

[0054] According to an alternative embodiment, the tubular part 111 of the body 110 can be driven into the internal circular bore 181 of the mounting ring 180.

[0055] The end collar 182 bearing on the counterbore 26 of the slot 21 forms a positioning stop and ensures the mounting of the correction member 100 when screwing, or driving in, the cylindrical body 110 from the outside of the middle 20.

[0056] The head 112 of the cylindrical body 110 is the part of the cylindrical body 110 remaining outside the caseband 20, that is to say on the side opposite the movement 1, the tubular part 111 and the mounting ring 180 cooperating at the level of the light 21 of the caseband 20.

[0057] The cylindrical body 110 comprises a shoulder 113 formed between the head 112 and the tubular part 111. The shoulder 113 forms a circular support or stop surface intended to receive the end of the mounting ring 180 opposite the end collar 182.

[0058] The shoulder 113 also makes it possible to form a mounting stop with the outer face 23 of the middle 20.

[0059] The correction member 100 further comprises a cylindrical control rod 120, with longitudinal axis XX. For example, the control rod 120 is a circular cylindrical rod, with axis of revolution XX.

[0060] The control rod 120 is configured to slide inside the cylindrical body 110, along the axis XX; and more particularly in an internal bore passing through the cylindrical body 110 arranged to receive the control rod 120.

[0061] The control rod 120 is coaxial with the cylindrical body 110.

[0062] The control rod 120 is secured to a pusher 130 which can be operated by the user from outside the box 2.

[0063] The control rod 120 comprises: a first end 121 directed towards the outside of the case 2 and secured to the pusher 130, for example by driving or screwing; a second end 122 directed towards the inside of the case 2 and intended to come into contact with a function corrector 10, 12 of the watch movement 1 and to actuate the latter, when the user exerts pressure on the pusher 130; a central portion 123 forming the junction between the first end 121 and the second end 122.

[0064] In reference to the figure 4 , the first end 121 of the control rod 120 has a thread, provided on a radially external face, to receive the pusher 130 by screwing.

[0065] The end 122 of the control stem 120 is intended to be positioned opposite the watch movement 1, and more particularly a function corrector 10, 12, a plurality of function correctors 10, 12 or even opposite no function corrector depending on the position of the correction member 100 in the caseband 20.

[0066] The pusher 130 has a general capsule shape configured to slide concentrically outside the cylindrical body 110, and more particularly the head 112. The pusher 130 comprises an internal recess in which a chimney 131 is formed, having in its center a threaded bore to receive the first end 121 of the control rod 120.

[0067] Conventionally, the correction member 100 may also comprise locking means for blocking the rotation of the pusher 130 with respect to the cylindrical body 110 around the axis of revolution XX.

[0068] By way of example, the locking means may be formed by the cooperation of projecting elements 125, for example grooves, provided on the radially external face (relative to the axis XX) of the periphery of the head 112 of the cylindrical body 110, and by recesses, of complementary shape, for example grooves, provided at the level of the radially internal face (relative to the axis XX) of the peripheral wall 135 delimiting the internal recess of the pusher 130. Of course, a different arrangement of the projecting elements and the recesses is also possible without departing from the scope of the invention.

[0069] The locking means thus make it possible to block the rotation of the pusher 130 relative to the cylindrical body 110.

[0070] According to an alternative embodiment (not shown), the rotation of the pusher 130 relative to the cylindrical body 110 is left free, so that the pusher 130 is free to pivot around the axis XX.

[0071] The return to a rest position of the correction member 100 is ensured by a return element 140, for example a return spring, positioned between the cylindrical body 110 and the pusher 130. Thus, the return element 140 tends to reposition the pusher 130 and the control rod 120 in a rest position when the user does not exert pressure on the pusher 130.

[0072] For this purpose, the cylindrical body 110 comprises an end cavity formed at the level of the head 112 and configured to receive a first end of the return member 140 in support. The second end of the return member 140 comes to bear at the level of the internal recess of the pusher 130.

[0073] The case 2 according to the invention comprises an indexing member 150 making it possible to define stable positions of the correction member 100 movable in the caseband 20. The indexing member 150 makes it possible, for example, to define at least two stable positions of the correction member.

[0074] The indexing member 150 advantageously makes it possible to indicate to the user, for example sensitively, that the correction member 100 is positioned correctly, thus avoiding positioning between two activation positions of the correction member 100. Thus, such an indexing member 150 makes it possible to ensure correct positioning of the end 122 of the control stem 120 opposite the timepiece movement in order to perform the desired function, for example actuating the first function corrector 10 and / or actuating the second function corrector 12 of the timepiece movement 1, or even positioning the correction member 100 in a neutral, or inactive, position, making it possible not to interact with the timepiece movement.

[0075] The indexing member 150 also makes it possible to ensure a stable position of the correction member 100 when the user exerts pressure on the pusher 130.

[0076] For example, the indexing member 150 is formed by several ball indexers with spring carried by the middle 20. More particularly, the ball indexers with spring are housed in bores 28 provided for this purpose in the middle 20. The indexers are configured to mark several stable positions of the movable correction member 100 in the slot 21.

[0077] The spring-loaded ball indexers are configured to cooperate with recesses 185 provided on the mounting ring 180, for example on the radially outer surface of the peripheral periphery of the mounting ring 180 as shown in FIG. figure 3 .

[0078] In the embodiment described, the case 20 comprises eight spring-loaded ball indexers, four spring-loaded ball indexers for each stable position.

[0079] In the embodiment described, the indexing member 150 has been described to define two stable positions of the correction member corresponding to two activation positions P1, P2 of the correction member 100, that is to say a first stable activation position P1 to activate the first function corrector 10, as shown in Figure 5a , and a second stable activation position P2 for activating the second function corrector 12, as shown in Figure 5b .

[0080] THE Figures 5a and 5b respectively represent the correction member 100 in a first activation position and in a second activation position.

[0081] However, it is possible to size the lumen 21 and configure the indexing member 150 to define a plurality of stable positions of the correction member 100.

[0082] For example, one of the stable positions P3 of the correction member 100, illustrated in Figure 5c , allows at least two function correctors 10, 12 to be actuated simultaneously when the user exerts pressure on the push button 130.

[0083] For example, one of the stable positions P4 of the correction member 100, illustrated in Figure 5d , is a disengaged or neutralized position configured to not activate a function corrector when the pusher 130 is pressed. For example, in such a position, the control rod 120 cannot actuate a function corrector of the clockwork movement.

[0084] Thus, according to an alternative embodiment, the stable positions of the correction member 100 in the case 20 can be defined as follows: a first position P1 of the correction member 100 positioning the control rod 120 opposite the first function corrector 10 for the purpose of activating it by pressing the push button 130, a second position P2 of the correction member 100 positioning the control rod 120 opposite the second function corrector 12 for the purpose of activating it by pressing the push button 130, and a third position P3 of the correction member 100, for example intermediate between the first position P1 and the second position P2, positioning the control rod 120 opposite the first function corrector 10 and the second function corrector 12 for the purpose of activating them simultaneously by pressing the push button 130.

[0085] The correction member 100 also comprises first sealing means 160 ensuring sealing in particular between the cylindrical body 110 and the control rod 120. The sealing member is for example formed by one or two O-rings superimposed on each other.

[0086] The case 2 also comprises second sealing means (not shown) configured to ensure sealing between the middle part 20 and the correction member 100, thus ensuring sealing between the inside of the case 2 and the outside of the case 2, while allowing the movements of the function corrector 100. The second sealing means are for example formed by a flexible membrane having a portion secured to the middle part 20 and a portion secured to the correction member 100, for example the cylindrical body 110.

[0087] The case 2 and the correction member 100 which have just been described make it possible to control several functions of a watch movement. The choice of the function of the watch movement 1 to be actuated is carried out by moving the correction member 100 from one to the other of the stable activation positions. For this, the user slides the correction member 100 by exerting a translational force on the correction member 100, via the pusher 130, according to the arrows referenced A1 shown in Figures 5a and 5b .

[0088] The sliding of the correction member 100 can be rectilinear or curvilinear.

[0089] In the illustrated embodiment, the correction member 100 can be moved rectilinearly in a direction perpendicular to the axis XX as shown in figures 2 , 5a and 5bIn the exemplary embodiment, the translational force to be exerted is substantially tangent to the outer face 23 of the middle part 20, at the level of the light 21.

[0090] According to an alternative embodiment, it may be provided to move the correction member 100 along an arc of a circle whose center is common to the center of the box 2. In this case, the shape of the light 21 is adapted to allow such curvilinear sliding.

[0091] When the correction member 100 is in position, the user actuates the correction member 100 by exerting pressure on the pusher 130 in a direction indicated by the arrow referenced A2 on the Figures 5a and 5b, parallel to the axis XX. The pressure exerted goes against the return element 140, moving the pusher 130 and the control stem 120 towards the inside of the case 2 and until they come into contact with the selected function corrector 10, 12. Additional pressure on the pusher 130 makes it possible to actuate the function corrector 10, 12 and to activate, select, reset or correct the function of said watch movement 1 associated with the function corrector 10, 12.

[0092] In the present application, the control stem 120 actuates two function correctors, of the rocker type, of a mechanical clockwork movement. However, it is envisaged that the control stem can interact with a function corrector of the electrical contact type making it possible to display, correct, select, engage, or reset at least one function derived from the current time of any mechanism.

[0093] The invention also relates to a case 2 comprising a timepiece movement 1 comprising at least two function correctors 10, 12 for displaying, correcting, selecting, engaging, or resetting to zero functions derived from the current time, such as for example a date, a time zone, a chronograph, etc., and at least one multifunction function corrector 100 according to the invention making it possible to select a function corrector 10, 12 of the movement 1 and to actuate the latter when the push-piece 130 is pressed.

[0094] The invention also relates to a timepiece, such as a wristwatch, comprising a case 2 containing a timepiece movement 1 comprising at least two function correcting members 10, 12 for displaying, correcting, selecting, engaging, or resetting to zero functions derived from the current time, such as for example a date, a time zone, a chronograph, etc.
