Definitions

  • the present invention relates to a device for adjusting the length of a bracelet, particularly suitable for a bracelet for a wristwatch provided with a folding clasp disposed between two ends of the bracelet. It also relates to a clasp and a bracelet as such, integrating such a device for adjusting the length of a bracelet, as well as to a timepiece such as a wristwatch as such comprising such a device.
  • a clasp with folding blades of the state of the art intended to hang the two strands of a watch bracelet around the wrist of its wearer, comprises several articulated blades, which can occupy a first closing position, in which the blades are folded on themselves, and a second opening position, in which the blades are no longer superimposed but are deployed and allow the watch to be put on or taken off.
  • Such a clasp is generally equipped with an adjustment for the length of the bracelet or a bracelet strand.
  • a general objective of the invention is to further improve the convenience of adjusting the length of a bracelet.
  • the invention aims to propose a solution for adjusting the length of a bracelet, the operation of which is reliable and the handling intuitive and user-friendly.
  • An advantage of the invention which will be described subsequently comes in particular from the fact that the adjustment does not require the watch to be removed from the wrist.
  • the invention aims to propose a solution for adjusting the length of a bracelet which fits best into the bracelet or the clasp in which it is arranged, in particular for aesthetic purposes.
  • the invention is based on a device for adjusting the length of a bracelet, in which an adjustment mesh is mounted movable in a longitudinal direction relative to a cover, so as to drive one end of a strand of bracelet in the direction of lengthening or shortening of a bracelet, this adjustment mesh being moved by the actuation of an actuating device arranged on a surface of the cover in a movable manner in said longitudinal direction and connected to the adjustment mesh by a first kinematic connection.
  • the adjective “upper” to designate a surface or any part intended to remain oriented away from a user's wrist when the bracelet is worn.
  • the top surface of a clasp cover will be the surface visible to the user when the clasp is closed on the wrist, as opposed to the hidden surface facing the wrist.
  • the vertical direction as a direction perpendicular to the longitudinal direction, oriented from the area intended to come into contact with a user's wrist towards the opposite area.
  • this direction will be for example perpendicular or substantially perpendicular to an upper surface of a cover, as will emerge from the following description.
  • transverse direction as the direction perpendicular to both longitudinal and vertical directions.
  • a device for adjusting the length of a bracelet according to a first embodiment of the invention will now be described, with reference to the figures 1 to 9 .
  • the device for adjusting the length of a bracelet is arranged within a clasp 1, which comprises two blades 2, 3 articulated together.
  • the second blade 3 is articulated with the first blade 2 and with a first part 4 of a cover 10 at its two respective ends, respectively by a first axis of rotation 5 and a second axis of rotation 6.
  • first blade 2 comprises a device for fixing to a first strand of bracelet 7 and to a second part of cover 8, arranged at its end opposite to its connection with the second blade 3.
  • the cover 10 comprises a device for adjusting the length of a bracelet, which will be described in detail later.
  • the clasp 1 can occupy a closed configuration, in which the two blades are folded in a superimposed manner, locked in this position, notably via the cover, and in which the bracelet is worn by a user, and a open configuration, in which the blades are deployed, so that the bracelet can be removed from one wrist.
  • FIG 1 depicts the clasp in an intermediate, semi-deployed configuration.
  • FIG. 2 represents more precisely the device for adjusting the length of a bracelet according to this first embodiment, in exploded perspective. This adjustment device is more precisely arranged within the cover 10 of the clasp 1.
  • the cover 10 comprises a main body 11 comprising two lateral parts symmetrical with respect to a vertical longitudinal median plane.
  • Each side part comprises an upper surface part 12 and a side wall 13 substantially perpendicular to the upper surface part 12.
  • a longitudinal groove 14 is arranged in the interior surface of each side wall 13.
  • Indexing and locking elements 15 are also arranged in these grooves 14, in the form of teeth, advantageously of square section. This toothing extends in a vertical longitudinal plane.
  • An intermediate base 16 connects the two lateral parts of the cover 10, at an intermediate or substantially intermediate height. It appears as a transverse plate comprising a central opening 17.
  • the device for adjusting the length of a bracelet comprises an actuation device 30 connected to an adjustment mesh 40 by a first kinematic link.
  • the actuation device 30 is presented as a movable surface in the longitudinal direction relative to the cover 10. This surface is arranged at the level of the upper surface of the cover 10 to complete it, in addition to the upper surface parts 12, and thus form a substantially continuous surface and aesthetically similar to that present on other clasps known to the state of the art.
  • the adjustment mesh 40 comprises two lateral pads 41, positioned respectively within each longitudinal groove 14 of the cover 10 to allow the longitudinal movement of the adjustment mesh 40 relative to the cover. According to this embodiment, these two pads 41 are arranged respectively at the two ends of a transverse rod 42.
  • the adjustment mesh 40 further comprises a fixing device for a bracelet strand. According to this embodiment, this fixing device is in the form of an axis 43 around which the first link of a second strand of bracelet 9 is arranged.
  • the adjustment link 40 further comprises at least one notch of drive 46 intended to allow its longitudinal drive. According to this embodiment, it comprises two substantially vertical drive notches 46.
  • the first kinematic connection makes it possible to connect the actuation device 30 to the adjustment mesh 40 to enable the adjustment mesh 40 to be driven from the actuation of the actuation device 30.
  • the operation will be detailed below .
  • This first kinematic connection comprises a first elastic return element 50, in the form of a first particular spring, arranged between the lower surface of the actuating device 30 and the base 16 of the cover 10.
  • this first spring is designed to exert multiple elastic returns of the actuating device 30, on the one hand in the longitudinal direction, in both directions, and on the other hand in the vertical direction.
  • the first spring is in the form of a spring cut out and embedded in its central part by two lugs 18 formed in the base 16 of the cover 10. It comprises a central opening 52 substantially superimposed on the central opening 17 of the base 16.
  • the first spring further comprises two curved flexible parts 53, of circular shape, having a section smaller than that of the body of the spring, which perform callback functions according to the different directions mentioned above.
  • this first spring also comprises two other curved flexible parts 54, of elongated shape, which also participate in the elastic return of the actuating device 30, in the vertical direction.
  • This first elastic return element 50 makes it possible more particularly to return and maintain the actuating device 30 in its rest position, preferably centered and aligned with respect to the base 16, and more generally with respect to the cover 10.
  • the first kinematic connection further comprises a rack 100, in the form of a flat plate comprising a notch in the form of holes 106 aligned regularly in the longitudinal direction, and the two drive notches 46.
  • the notching comprises two parallel series of holes 106, arranged at a spacing corresponding to that of the two driving notches 46.
  • the rack 100 On its two longitudinal ends, the rack 100 comprises inclined portions 107 upwards, substantially perpendicular to the rack, which rises towards the actuation device 30 so as to join with corresponding assembly portions 37 of the actuation device. By this assembly, the rack 100 is movable in the longitudinal direction in a movement linked to that of the actuating device 30.
  • the device for adjusting the length of a bracelet further comprises a locking device, which can occupy two configurations: a first locking configuration in which it acts on the adjustment mesh 40 by preventing its movement relatively to the cover 10, and an unlocking configuration in which it releases the adjustment mesh 40, which is thus movable relative to the cover 10 to carry out an adjustment.
  • this locking device is produced via locking notches 44, preferably of square section, arranged respectively at the two ends of the transverse rod 42 of the adjustment mesh, and designed to cooperate with indexing and locking elements 15 arranged at the level of the longitudinal groove 14.
  • the rod 42 advantageously appears as a spring bar.
  • the locking device is actuated by the actuation device 30.
  • the locking device further comprises a second kinematic connection, which connects the actuating device 30 to the locking device, so as to allow locking or unlocking by actuation of the actuating device 30.
  • This second kinematic connection comprises an intermediate element 60 and a second elastic return element 70, which is in the form of a flat or substantially flat leaf spring, designed to deform over its width, in particular to change convexity.
  • the spring bar forming the rod 42 is elastically returned by the leaf spring against the intermediate element 60 so as to position the locking notches 44 between two indexing and locking elements 15, thus positioning the locking device in its configuration locking.
  • the intermediate element 60 is in the form of a pusher that can also be moved in a vertical direction. It is intended to be actuated against the second elastic return element 70 so as to move the spring bar downwards, and thus release the locking notches 44 of the indexing and locking elements 15 ( Figure 6 ).
  • THE figures 3 and 4 illustrate the device for adjusting the length of a bracelet in section by a vertical longitudinal median plane.
  • FIG 3 illustrates the adjustment device in locked configuration, at rest.
  • the locking notches 44 of the elements are positioned between two indexing and locking elements 15, and the driving notches 46 are released from the holes 106 of the rack 100.
  • Figure 4 illustrates the adjuster in unlocked configuration. It can be seen that the actuating device 30 was actuated by vertical downward pressure, by a simple central support on its upper surface 31. This pressure has the effect of crushing the first spring forming the first elastic return element 50 against the base 16. By this actuation, the notching of the rack 100 comes into engagement with the driving notches 46. More precisely, these driving notches 46 are positioned within holes 106 of the rack 100.
  • the rack 100 transmits support to the intermediate element 60, which likewise transmits support to the rod 42, which is moved downwards against the second elastic return element 70, which is deformed .
  • the rod 42 is moved vertically so that its locking notches 44 escape the indexing and locking elements 15.
  • the adjustment mesh 40 is no longer locked and can be actuated in longitudinal movement.
  • the adjustment device is then in the unlocked configuration.
  • FIG. 5 illustrates the adjustment device at rest, in the same configuration as that of the Figure 3 explained previously. It thus appears that the rack 100 is not engaged with the driving notches 46 of the adjustment mesh 40. In addition, the locking notches 44 are engaged with indexing and locking elements 15, locking there adjustment mesh 40 in its longitudinal position, and therefore locking the bracelet length adjustment device. This rest position is stable, because the first elastic return element 50 maintains the actuating device 30 stably in its rest position.
  • FIG. 6 illustrates an intermediate adjustment position, in which the device for adjusting the length of a bracelet is in an unlocked configuration, similar to that of the illustration of the Figure 4 .
  • the actuating device 30 has been driven downwards, as explained in relation to the Figure 4 .
  • FIG. 7 illustrates the implementation of a length adjustment of the bracelet, in the direction of its shortening.
  • the vertical downward pressure on the actuator 30 is maintained and the latter is moved in the longitudinal direction, to the left on the Figure 7 .
  • These actuations drive the adjustment mesh 40 in the same longitudinal movement via the first kinematic connection.
  • the longitudinal travel of the actuating device 30 is limited by one or more stops.
  • this stroke is defined by the length of the central opening 17 of the base 16, which forms stops for the movement of a protrusion 33 of the actuating device 30.
  • This maximum longitudinal stroke of the device actuation 30 is advantageously provided so as to be able to slide the adjustment mesh 40 by a step or a multiple of steps corresponding to the step between two consecutive indexing and locking elements 15.
  • An adjustment of the length of the bracelet can thus correspond to a translation or a succession of translations of the actuating device 30, from its rest position to a longitudinal stop.
  • the pitch of the rack 100 that is to say the pitch between two holes 106, is identical to the pitch between two elements indexing and locking 15. The arrangement is thus shaped so that the drive notches 46 are always facing a hole 106 in the rack 100 when the locking notches 44 are facing a housing provided by the indexing and locking elements 15.
  • the user releases the pressure on the actuating device 30.
  • the double elastic return of the two elastic return elements 50, 70, the actuation device 30, as well as the elements of the first and second kinematic connections go up in the vertical direction.
  • the locking notches 44 of the adjustment mesh rise in the same way, under the effect of the rise of the rod 42, to be housed between two indexing and locking elements 15.
  • the rack 100 is in its high position, out of reach of the drive notches 46 of the adjustment mesh 40.
  • the figure 8 represents the device in this configuration.
  • the user completely releases the actuating device 30, which returns to its initial rest position thanks to the return force applied by the first elastic return element 50, that is to say the first spring.
  • the actuating device 30 also returns to its rest position in the longitudinal direction, preferably centered, due to the elastic return in the two vertical and longitudinal directions of said first spring.
  • Figure 9 illustrates this rest configuration.
  • An adjustment consisting of increasing the useful length of the bracelet can naturally be implemented in a very similar manner, by moving the actuating device 30 in the other direction of the longitudinal direction, that is to say towards the right on THE figures 5 to 9 .
  • the adjustment mesh 40 when the adjustment mesh 40 reaches an extremal position within the groove 14 of the cover 10, it is at a stop and can only move in one direction in the longitudinal direction.
  • the actuating device could be driven by a double movement in the longitudinal and transverse directions, replacing the longitudinal and vertical directions of the embodiment described.
  • the first kinematic link would be modified for such an achievement.
  • first and second kinematic connections could be different from those shown as examples.
  • THE figures 10 to 17 illustrate a device for adjusting the length of a bracelet according to a second embodiment. This adjustment device is always arranged within a clasp 1, as shown in the figure 1 .
  • the actuating device 30 is only movable in the longitudinal direction, in both directions, and stationary in the vertical direction, as well as in the transverse direction. It is thus only movable in one direction, and no longer in two directions as in the first embodiment.
  • This device for adjusting the length of a bracelet thus differs from that according to the first embodiment in that the movement of the actuating device 30 in the longitudinal direction alone is sufficient to induce the two functions of unlocking a link.
  • adjustment 40 and longitudinal movement of the adjustment mesh 40, for adjusting the length of a bracelet are examples of the adjustment mesh 40, for adjusting the length of a bracelet.
  • the first kinematic connection comprises a first elastic element 50, which comprises two helical springs, arranged in the longitudinal direction within an opening of the base 16, so that a first end is fixed on the base 16, and a second end rests on a lower protuberance 32 of the actuating device 30.
  • the two helical springs exert a return force on the actuating device, in the longitudinal direction, in both directions, which allow its return to a rest position centered in relation to the cover 10.
  • the first kinematic connection further comprises a conversion element 80, arranged on the lower surface of the actuating device 30 integrally with this actuating device in the longitudinal direction but movable in the transverse direction, and an element forming a surface cam, which we will simply call first cam surface 110, integral with the actuating device 30, disposed under the conversion element 80.
  • the conversion element 80 comprises a guide profile 82 arranged on its side, intended to cooperate with a second cam surface 19 arranged on the lateral flanks of the central opening 17 of the base 16, in a transverse longitudinal plane, in which the base 16 is arranged.
  • This second cam surface 19 of the base 16 notably comprises projections extending in transverse direction, allowing the guidance of the conversion element 80 in the transverse direction.
  • a third spring 120 acts on the conversion element 80 so as to maintain its guide profile 82 against the second cam surface 19 of the base 16, by an elastic return force in the transverse direction.
  • this third spring 120 is in the form of a wire spring resting on a lug secured to the actuating device 30.
  • the transverse position of the conversion element 80 is thus defined by the second cam surface 19 of the base 16, as a function of the longitudinal position of the actuating device 30 relative to the base 16 of the main body 11 of the lid.
  • the conversion element 80 further comprises guide elements 86, arranged under its lower surface, intended to cooperate with a drive notch 46.
  • the drive notch 46 is not not directly arranged on the adjustment mesh, but on the upper surface of an intermediate element 60 arranged within an adjustment mesh 40.
  • the locking notches 44 are also arranged on this upper surface of said intermediate element.
  • the first cam surface 110 also comprises a profile comprising projections 112 arranged in a central opening 117, capable of cooperating with the drive notch 46 of the intermediate element 60.
  • the base 16, the first elastic return element 50, the conversion element 80 and the third spring 120 are interposed between the actuating device 30 and the first cam surface 110. This arrangement allows you to keep all of these elements assembled on the clasp cover.
  • the intermediate element 60 is arranged in a housing 47 of the adjustment mesh 40, oriented in the transverse direction, movable in this direction.
  • a second elastic return element 70 which is a helical spring according to this embodiment, acts on this intermediate element 60 so as to return it elastically in the transverse direction towards its rest position, thus acting both on the notch of locking 44 and on the drive notch 46.
  • the adjustment mesh 40 likewise comprises a transverse rod 42 comprising pads 41 on its ends, which slide in longitudinal grooves 14 arranged in the side walls 13 of the cover, to thus guide the longitudinal movement of the adjustment mesh 40 during 'an adjustment of the length of a bracelet.
  • the first kinematic connection thus forms a movement conversion device, which makes it possible to convert a longitudinal translation movement of the actuation device 30 into a succession of movements within the device for adjusting the length of a bracelet, as will be detailed later.
  • the second kinematic connection makes it possible to perform the locking function, from the actuation device 30.
  • the locking function is provided from indexing and locking elements 15 arranged laterally on the base 16, and no longer within the longitudinal grooves 14. These indexing and locking elements 15 are arranged in a transverse longitudinal plane, in which the base 16 is arranged. These indexing and locking elements 15 cooperate with one or more locking notches 44, as mentioned previously.
  • THE figures 12 to 17 represent more precisely the operation of the device for adjusting the length of a bracelet according to this second embodiment, in top view highlighting the components of the kinematic connections to clearly illustrate the operation.
  • FIG. 12 illustrates the device for adjusting the length of a bracelet at rest, in an intermediate position for adjusting the length of the bracelet.
  • the drive notch 46 is disconnected from the drive profiles of the first cam surface 110 and the conversion element 80.
  • the intermediate element 60 is further in a position in which its locking notches 44 are engaged with the indexing and locking elements 15, so that its positioning is locked.
  • a user activates the actuating device 30 by moving it in the longitudinal direction, towards the left on the figures 12 to 17 depending on the example chosen.
  • This actuation causes the conversion element 80 to move until a guide element 86 comes into engagement with the drive notch 46 of the intermediate element 60, as shown in the figure. Figure 13 .
  • a guide profile 82 of the conversion element 80 comes into contact with a projection of the second cam surface 19 of the base 16.
  • An intermediate configuration is represented by the Figure 13 .
  • the longitudinal movement of the actuating device 30 is continued until reaching a stop which predefines its maximum travel as a function of the entire arrangement.
  • This stroke corresponds to a step of the indexing and locking elements 15.
  • the guide profile 82 of the conversion element 80 has crossed the projection of the second cam surface 19, and the element of conversion 80 is driven in opposite transverse movement by another projection of the second cam surface 19 cooperating with the guide profile 82 on the other side of the conversion element 80, and under the effect of the second elastic return element 70 and the third spring 120.
  • the longitudinal stop in this overall movement is made between the guide profile 82 of the conversion element 80 and the cam surface 110.
  • This movement repositions the locking notch 44 in a new notch of the indexing and locking element 15, which again locks the intermediate element 60, and indirectly the adjustment mesh, in this new position which corresponds to a reduction in the length of the bracelet, more precisely of the second bracelet strand.
  • This configuration is illustrated by the Figure 15 .
  • FIG. 16 illustrates an intermediate position of the actuating device 30 during its return movement.
  • the guide profile 82 of the conversion element 80 comes back into contact with the projection of the second cam surface 19.
  • the drive notch 46 is driven in the direction transverse so as to release from its grip the drive notch 46 of the intermediate element 60.
  • the movement is continued until the actuating device 30 returns to its rest position, as represented by the Figure 17 .
  • this new position represented by the Figure 17 corresponds to the maximum shortening of the useful length of the bracelet. Therefore, if the actuating device were to be requested again in the direction of shortening, the first kinematic connection would simply not make it possible to further drive the adjustment mesh.
  • the elongation of the bracelet will be obtained in a very similar manner, by actuation of the actuating device 30 in the other direction of the longitudinal direction (towards the right on the figures 12 to 17 ).
  • the actuating device is integrated homogeneously and continuously on the upper surface of the cover. It is preferably centered on the upper surface of the cover and/or forms a central portion of the cover, in a rest position. It extends advantageously over the entire length of the lid. This upper surface thus forms a continuous surface of the cover substantially parallel to the upper surface of a bracelet strand which would be fixed to the adjustment mesh.
  • the actuating device could take any other shape arranged at the upper surface of the cover.
  • the actuating device could not be arranged on the upper surface of the cover, but for example on a lateral surface, its movement remaining in the longitudinal direction and optionally in another direction.
  • the adjustment device could not include a locking device, which is therefore optional.
  • the actuating device and/or the first kinematic link could be such that it is sufficient to reduce the risk of accidental modification of the length adjustment, without a locking device.
  • the movements of the actuating device could be locked by a safety device. This safety device could be the same as the one that prevents the clasp from accidentally opening.
  • the locking device could be actuated by a second actuation device, a locking/unlocking element, distinct from the first actuation device making it possible to complete the length adjustment alone, instead of being confused with the latter as in the embodiments described.
  • This second actuation device could be driven by a movement different from that of the first actuation device, in particular in another direction.
  • the locking device could comprise locking elements having any shape, not necessarily a notch as shown, but also for example simple braking by friction.
  • the adjustment device has been described with two or three elastic return elements. A different number of elastic return elements is of course possible.
  • adjuster has been described as integrated within a clasp cover. Alternatively, it could be integrated into any lid, not necessarily with a clasp. This cover could take any shape, even very light.
  • the adjustment link has hitherto been described as an independent element of a bracelet, which comprises a fixing device for a strand of bracelet, in particular in an articulated manner.
  • this fixation could be different, without degrees of freedom.
  • the adjustment mesh could be completely integrated into a strand of bracelet. It could therefore form a single piece with a strand of bracelet. We therefore generally consider that the adjustment mesh is designed to be linked to a strand of bracelet, to cover all these achievements.
  • the adjustment device could for example be arranged within a lug of a watch case, a fixing, a handle cover, a link or a strand of bracelet, a middle part or a case back. More generally, this adjustment device could be arranged within any element of the watch which participates directly or indirectly in the constitution or assembly of the bracelet with the watch case.
