Definitions

  • the present invention relates to the field of watchmaking, and in particular to a clasp for a wristwatch. It relates even more particularly to a clasp for a diver's watch.
  • clasps using a buckle and a barb are known, in which one of the strands of the clasp is pierced with several holes regularly spaced from each other. To define the length of the bracelet, the barb is introduced into one of the holes to define the desired length and locking is then obtained by introducing the remaining length of the pierced strand into a hoop formed above the other strand.
  • clasps of the type with a folding clasp with two branches folded over one another in the closed position are known, and which allow the user to insert his wrist into the bracelet in the open position without having to separate the two strands thanks to the increase in diameter conferred.
  • Such an arrangement makes it possible to improve safety and comfort of use, by making it possible on the one hand to simply put the wristwatch on one's wrist, and to remove it just as quickly and efficiently, without having to separate the strands from the wristband; on the other hand, such combined strap attachment and locking devices make it possible to prevent the watch from falling if the two strands were to separate from each other in the event of a malfunction of the locking system.
  • three-arm devices are also known, also called “butterfly”, where two small side arms arranged symmetrically and hinged around the ends of a central arm fold into the center thereof.
  • One of the most basic solutions that has been proposed for folding clasps is to provide a plurality of pairs of holes on a cover in which it is possible to house bars for fixing one of the ends of a strand. In this way, the spacing between two pairs of adjacent holes defines an adjustment step for the useful length of the bracelet.
  • Such a solution described for example in the patent application EP0913106A1 , however, has the disadvantage of having to use a small pointed tool to perform the adjustment, which therefore cannot be easily performed by the wearer of the watch himself.
  • the patent EP0350785B1 describes an alternative solution presenting a device for adjusting the length making it possible to carry out the adjustment in a simpler way using a trigger actuated by the user himself using a pusher.
  • a hook arranged at the end of one of the blades can come to engage in several holes provided in a second blade formed in two sliding parts relative to each other.
  • the trigger releases and locks the hook, and the length adjustment is then made by sliding the blade until the next hole is opposite the hook.
  • the disadvantage of such a system is to require the complete opening of the clasp to be able to perform the adjustment, which is impossible as long as the hook is positioned in one of the holes.
  • An object of the present invention is to provide an alternative solution of a folding clasp, which is provided with a locking and adjustment device that can be operated more intuitively by a common control member.
  • Another object of the present invention is to provide a clasp of simple and elegant construction.
  • a clasp with a folding clasp for a wristwatch comprising at least a first branch and a second branch hinged with respect to each other around an axis, the clasp comprising on a apart from a locking device to hold the first branch and second branch in the folded position one on the other in the closed position of the clasp, and on the other hand a device for adjusting the useful length of said bracelet comprising a connecting element mounted to slide under a cover of the clasp, and a stop element cooperating with this sliding connecting element, as well as a control member that can be actuated from a rest position to an active position.
  • the clasp is characterized in that the end of the second branch opposite the axis comprises means of attachment to a first strand of the bracelet and that the end of the first branch opposite the axis is connected in an articulated manner to the sliding connecting element, and that the control member is arranged so as to be able, when it is in the active position, both to cause the unlocking of the clasp by acting on a locking element, and to release the 'sliding connecting element of the stop element, the sliding connecting element can then be moved, when the control member is in the active position, independently of the open or closed position of said clasp.
  • Another advantage conferred by the proposed solution is to be particularly compact and discreet. Indeed, not only the locking mechanism, but also the adjustment mechanism are mounted under a cover.
  • the clasp with a folding clasp for a wristwatch according to the invention is characterized in that the locking element consists of hooking means coming into engagement against lower bearing surfaces of the second branch.
  • this solution has the advantage of minimizing the total height of the system compared, for example, with conventional solutions using fixing studs arranged on one of the blades collaborating with clamping jaws.
  • the clasp with folding clasp for a wristwatch is characterized in that the hooking means are retractable hooks bearing against shoulders arranged inside a first leg and a second leg of a stretcher forming the second branch.
  • the locking device is produced in a particularly simple and intuitive manner in combination, for example, of retractable hooks with side pushers; moreover, the arrangement of the locking device entirely inside the lid towards the stretcher makes it possible to avoid any protruding shape outside the frame of the lid, while minimizing the total volume of the system by occupying the gap between the two stretcher legs.
  • the internal shoulders provided inside the legs of the stretcher make it possible on the one hand to prevent any flushing of the hooks against the skin, and thus to avoid any pinching and consequently to improve the wearing comfort of a wristwatch equipped with such a clasp; these shoulders make it possible, moreover, to further minimize the total thickness of the combined system provided for locking and adjustment.
  • the folding clasp for a wristwatch is characterized in that the stopper element of the adjustment device is formed by at least one tooth engaging with notches a rack arranged inside said sliding connecting element.
  • An advantage of such an arrangement of the adjustment device is to be particularly simple to implement, while once again minimizing the volume requirements.
  • the teeth and notches of the rack have a surface perpendicular to the longitudinal direction of the clasp and an oblique direction oriented in the direction of the narrowing of the useful length of the bracelet.
  • the clasp with a folding clasp for a wristwatch according to the invention is characterized in that the adjustment device is housed in a first compartment arranged entirely under the lid of the clasp.
  • the proposed solution has a modular construction that can leave room for the integration of other devices under the cover, and also has a particularly advantageous aesthetic appearance by concealing the locking and adjustment devices from the outside of the lid.
  • the folding clasp for a wristwatch according to the invention is characterized in that the sliding connecting element can move between a first shortened adjustment position and a second position adjustment, the sliding connecting element being entirely concealed on the one hand under the cover and on the other hand under a cover fixed removably to the cover in the first shortened adjustment position, and always concealed under the cover even in the extended second position.
  • the clasp with a folding clasp for a wristwatch according to the invention is characterized in that the control member consists of at least one push button housed in a side opening of said cover.
  • two pushers arranged symmetrically on either side of the cover will be taken so as to facilitate their gripping and make handling particularly intuitive, as on known folding clasps without an adjustment mechanism, the advantage It is well known for such pushers in the context of the present invention being that they make it possible to simultaneously actuate the setting without having to open the clasp at the same time.
  • the folding clasp for a wristwatch is characterized in that the push-button is actuated from the rest position to the said active position by acting against means return elastics arranged perpendicular to the longitudinal direction of said bracelet towards the inside of the cover, the locking element being formed by a retractable hook and the stop element being formed by a tooth, and the retractable hook and the tooth being integral with said pusher.
  • the retractable hook and the tooth are formed in one piece with said push button.
  • This variant thus has the advantage of a particularly simple and compact construction for integrating and merging three functional elements generally distinct from each other, namely a control member, a locking element formed by the retractable hook and the tooth as adjusting device stop element.
  • a control member namely a control member, a locking element formed by the retractable hook and the tooth as adjusting device stop element.
  • control member and respectively the tooth and the retractable hook are movable in planes superimposed on each other in the direction of the thickness of the cover.
  • the retractable hook is precisely mounted through a window of the cover.
  • the adjustment mechanism is completely concealed under the cover, and the locking device simply appears from below as a solution using retractable hooks.
  • the adjustment device is thus totally separate and invisible in relation to the locking device.
  • the folding clasp for a wristwatch according to the invention is characterized in that the elastic return means are formed by a first elastic return element and a second elastic return element arranged parallel to the 'one relative to the other in a direction perpendicular to the longitudinal direction of the bracelet.
  • the folding clasp for a wristwatch is characterized in that it also comprises a device for extending the useful length of the bracelet housed in a second compartment arranged entirely under the cover of the clasp.
  • An advantage of such a solution is that it allows on the one hand a modular construction for the integration of both the device for fine adjustment of the length of the bracelet and the usual extension device of diving watches for passing the watch above a neoprene suit, but also particularly refined and aesthetic because each of the two adjustment and extension devices offered are perfectly concealed under the clasp cover.
  • the folding clasp for a wristwatch is characterized in that the extension device comprises an attachment part to a second strand bracelet forming a hinge with an intermediate link pivotally fixed relative to the cover, a cylindrical locking pin of the intermediate link able to fit into a transverse groove for fixing the attachment part in the retracted position of the extension device.
  • the clasp 100 will also be described in various positions to highlight the operation of the opening of the clasp 100 and its adjustment.
  • FIG 1 shows the clasp 100 in the closed position, and thus highlights the particularly refined aesthetic conferred by the fact that the entire opening and adjustment mechanism is hidden under the cover 7.

  • first attachment means 33 of a first strand bracelet B1 which here preferably consist of a first fastening strip 35 arranged between a first pair of attachment lugs 34.
  • the other end of the second branch 3 is positioned under a second pair attachment horns 812 forming, with the second fixing strip 83, second attachment means 81 for the second strand B2 of the bracelet.
  • the second bracelet strand B2 is not directly connected to the cover 7, but connected to the latter via an extension device 8 which is also at least partially hidden under the cover 7 during normal use of the watch, that is to say when it is not necessary to have recourse to an extension of the bracelet of at least 10 millimeters, and preferably of approximately 15 to 20 millimeters to pass the strap over a neoprene wetsuit.
  • This extension device 8 is fixed to the cover 7 via third attachment means 741, inserted into fixing holes provided in the side walls 74 of the cover.
  • extension device 8 only constitute connecting means intermediate between the cover 7 and the second strand B2 of the bracelet, and that this second strand B2 could, according to a variant not shown, also be attached directly to the cover 7 and not only indirectly thereto.
  • push-buttons On either side of the cover 7, inserted into side openings provided for this purpose in the side walls 74 of the bracelet 7, are provided push-buttons, namely a first push-button 5A and a second push-button 5B , which together form a control member 5 for preferably actuating both the unlocking of the clasp 100 and the adjustment of the length of the bracelet.
  • extension device 8 The detail of the extension device 8 is illustrated at the top right of FIGS. 8A and 8B, with the intermediate link 82 formed by a first side link 82A and a second side link 82B connected to the cover 7 via the fourth fixing bar 821, and the connecting pin 882 inserted into the central through hole 8110 of the central link 811 of the second attachment means 81 from which the third attachment horn 812A of the second pair of attachment horns 812 can be discerned, as well as the associated third fixing hole 8210A, the fourth attachment horn 812B as well as the fourth fixing hole 8120B being hidden in this figure, but visible for example on the Figure 3B described later.
  • a transverse fixing groove 813 intended to receive the transverse fixing pin 812 when the intermediate link 82 is bent at 180 degrees with respect to the configuration illustrated in this figure, corresponding to that for example of the Figure 3B .
  • a slight elastic deformation is necessary, which it is possible to apply to one or the other of these elements generally preferably made of metal.
  • the shape of the transverse fixing groove 813 is preferably provided such that insertion is facilitated at the edge, and that retention is ensured at the bottom of the groove, for example by means of a slight curvature towards the inside requiring a greater deformation to pass behind but at the same time producing an upward retaining stop keeping the pin at the bottom of the groove.
  • the adjustment device 45 connects the cover 7 to the front end (first end 21) of the first branch 2 via the sliding connecting element 4.
  • This sliding connecting element 4 is arranged, for questions of aesthetic and ergonomic order - in particular to avoid any pinching - under a cover 70 fixed here by screwing to the internal face of the cover 7.
  • the first fixing screw 712A is inserted into a first fixing through hole 701A, tapped or not, corresponding and the second fixing screw 712B in a second fixing through hole 710B, tapped or not, arranged in a front bulge 701 making it possible to create sufficient space in height to accommodate the sliding connecting element 4.
  • a spoiler 702 which delimits a first compartment under the lid, illustrated later in particular on the figures 4A to 4C .
  • the cover 70 is also provided with a first window 70A and a second window 70B constituting orifices intended to let the locking hooks pass - that is to say the first locking hook 53A secured to the first button- pusher 5A and the second locking hook 53B integral with the second push-button 5B - being inserted, in the closed position of the clasp 100, under the second branch 3, and here more exactly under a first shoulder 36A of the first leg 3A and a second shoulder 36B of the second leg 3B.
  • the connecting element 4 is slidably mounted under the cover 7, but is fixed with respect to the first end 21 of the first branch 2, to which it is connected via the fixing axis 24, and therefore relative to the first strand B1.
  • the sliding connecting element 4 is thus mounted between the underside of the cover 7 and the cover 70 so as to be able to move only according to a degree of freedom in translation, and in an indexed manner according to different adjustment positions, according to the number of notches of the rack 42.
  • the fixing pin 24 preferably consists of an elastic bar introduced on the one hand into a first through fixing hole 210 of the first end 21 of the first branch 2, and on the other hand in the second fixing through hole 41A and the third fixing through hole 41B provided at the level of the front end 41 of the sliding connecting element 4, which is closed behind the first lateral toothing 42A and the second lateral toothing 42B by a crosspiece forming the rear end 43.
  • the clasp 100 determines a shortened, intermediate and elongated position for the useful length of the bracelet, while that illustrated by the figure 2B only has a shortened position and an extended position, spaced however by the same adjustment pitch as that corresponding to the other variant.
  • the adjustment step between each of the positions of the variant of the figure 2B is between 2.5 and 4 millimeters, so that the difference between the minimum and maximum length of the bracelet is between 5 and 8 millimeters.
  • the adjustment pitch is preferably between 6 and 7 millimeters.
  • the sliding connecting element 4 is fixed relative to the two branches, and therefore relative to the first bracelet strand B1 which is connected via the first attachment means 33, that is to say a barrette (not shown on these figure 2A And 2B ) inserted between a first pair of horns 34 each provided respectively with a first fixing hole 340A and a second fixing hole 340B. It nevertheless slides with respect to the cover 7, and therefore of the control member 5 formed by the first push-button 5A and the second push-button 5B, which are themselves fixed with respect to the cover 7 since they are arranged in openings insertion side arranged in the side walls 74 of the lid.
  • the two push-buttons are connected to each other via elastic return means 6, formed here by a first elastic return element 61 and a second elastic return element 62 which consist of sorts of spring bars or pawls , the ends of which are inserted, for example but not necessarily by press-fitting, into insertion orifices provided on the internal face of the push-buttons, that is to say opposite their protruding curved part intended to be manipulated by the user.

  • the second elastic return element 62 has a third insertion pin 62A and a fourth insertion pin 61B intended to be fitted respectively in a second insertion hole 52A of the first push button 5A and a fourth insertion hole 52B of the second push button 5B.
  • the advantage of such a configuration for the elastic return elements is to guarantee the stability of the movement of the pushers when they are pushed in when the user tries to cause the unlocking of the clasp and/or to actuate the adjustment device 45.
  • the push buttons each respectively have both a locking element and an integrated stop element, which act in superimposed planes.
  • the first push button 5A has a first retractable hook 53A, which is disengaged from its bearing surface formed by the first shoulder 36A below the first leg 3A of the second branch 3 when a force F is exerted. towards the inside of the cover (NB: this force is not illustrated in these figures for reasons of readability but represented on the figure 5B ).
  • the second push-button 5B has a retractable hook 53B, which bears under the second shoulder 36B of the second leg 3B in the closed position of the clasp, that is to say when the first end 21 of the first branch 2, opposite its second end 22 at the level of the axis of articulation 23 with the second branch 3, is interposed between the third ends 31A of the first leg 3A and fourth end 31B of the second leg 3B of the second branch 3.
  • the stop elements interacting with the teeth of the rack are masked - one can barely discern the first stop tooth 54A supposed to cooperate with the first lateral toothing 42A of the rack 42 of the connecting element 4 sliding. For this reason, the detail of the configuration of the stop elements will be explained in view of the Figures 4A-4C and 5A-5B.
  • the distal ends of the first and second legs 3A, 3B of the stretcher forming the second branch 3 have an indentation of length E relative to the thickness of the legs at their proximal end vis-à-vis the axis of articulation 23 with respect to the first branch 2.
  • the proximal end of the second branch has been referenced 32 and consequently the proximal end of each of the legs of the stretcher referenced 32A and 32B, respectively for the first leg 3A and the second leg 3B.
  • this notch does not correspond to the maximum possible travel for the adjustment, which is materialized by the reference C, also illustrated further on the figure 5B .

  • FIG. 3A shows a view of the clasp 100 in the closed position, in accordance with the figure 1 , but this time seen from below.
  • all the references already mentioned in detail in the context of the description of the figure 1 And 2A-2B will not be reintroduced in full in the description of this figure.
  • the only references to introduce are those which were masked in the previous figures, and in particular the fourth fixing hole 8120B of the fourth attachment horn 821B, as well as the second connection hole 741B of the third attachment means 741 , all the others having already been introduced.
  • FIG. 3A shows the clasp 100 in the closed position, but also the pusher in its rest position (Pr), that is to say not depressed.
  • the retractable hooks 53 - that is to say the first retractable hook secured to the first push-button 5A and the second retractable hook 53B secured to the second push-button 5B are resting on their surfaces respective locking, the first shoulder 36A under the first leg 3A being here particularly highlighted.
  • Such shoulders forming a sort of “intermediate step” make it possible to minimize the total height of the clasp, and thus its overall size. They also and above all make it possible to minimize any risk of pinching or discomfort worn at the level of the wearer's wrist by not generating any prominent shape at the level of the internal face of the clasp, that is to say under the first leg 3A and the second leg 3B.
  • FIG. 3B shows the same clasp 100, that is to say according to the same preferred embodiment as that illustrated by the preceding figures, but in the now open position.
  • the comparison between the figure 3A And 3B highlights one of the major advantages of the present invention, that is to say that dissociating the adjustment from the position of the clasp 100.
  • the adjustment can be carried out both in the open or closed position, and thus does not require unlocking the clasp to carry out the adjustment operation, as is often the case according to the solutions of the prior art and which constitutes a constraint not appreciated by users. In this way, user-friendliness is greatly improved.
  • the depression of the first and second pushers 5A, 5B causes the disengagement of the first and second retractable locking hooks 53A, 53B and thus allows any adjustment operation, regardless of the fact that the latter are located close to their bearing surfaces respective when locking, that is to say the first shoulder 36A and the second shoulder 36B.
  • FIG. 3B makes it possible to highlight the separate and superimposed gear planes between the adjustment device 45, just below the cover 7, and the locking mechanism, arranged one floor below. It also highlights the compactness of a clasp 100 made for a diver's watch with the adjustment device 45 arranged in a first compartment on the left under the clasp 100, and the extension device 8 placed right next to it so modular. According to the configuration illustrated, the extension device 8 is in the retracted position Pn, that is to say in the context of normal use, not corresponding to the diving mode. In this folded configuration of the intermediate link 82 and the central link 82, one can note the similarity between the two side links (first side link 82A and second side link 82B) of the intermediate link 82 and the stretcher of the folding clasp of the clasp.
  • FIG. 3B also makes it possible to highlight, in addition to the compactness of the combined locking and adjustment device, the effectiveness and aesthetics of the concealment of the proposed adjustment mechanism.
  • the adjustment device 45 proposed in the context of the present invention remains hidden under the cover 7, interposed between the latter and the cover 70, regardless of the adjustment position, that is to say in the shortened or extended position.
  • the cover 70 is screwed under the cover 7 so that the after-sales service is also greatly facilitated due to the removable nature of the fixing of the latter.
  • constituent parts of the clasp can be replaced in a modular fashion without requiring the entire clasp to be changed if any problem were to arise.
  • FIG 4A which illustrates a bottom view of the cover 7 taken in isolation, thus highlights the two compartments in which are intended to be housed respectively the adjustment device 45 and the extension device 8 illustrated on the Figure 3B previously described.
  • the first internal compartment 71 of the cover 7 is thus intended to receive the adjustment device 45 while the second internal compartment 72 of the cover 7 is provided to receive, in a modular fashion, the extension device.
  • an internal bulge 711 is provided towards the center of the first internal compartment 71 of the cover, which is provided with a first tapped blind hole 710A and a second tapped blind hole 710B, in which the first fixing screw is respectively inserted 712A and the second fixing screw 712B.
  • Such an arrangement makes it possible to carry out the removable fixing of the cover 70 simply, by screwing, without however risking damaging the exterior appearance of the cover 7 or having to modify the thickness of its upper outer wall.
  • THE figures 4B and 4C show, in addition to figure 4A , how the push-buttons are mounted on the cover 7 and how the locking 53 and stop 54 elements are integrated into the control member 5, that is to say to form a single piece made of a single piece, for example by molding.
  • FIG 4B shows in particular the first fixing hole 51A and the third fixing hole 51B intended to receive the ends of the first elastic 61 and of the second elastic element 62 and which were hidden in the previous figures;
  • THE figures 4B and 4C distinctively show the shape and arrangement of a stop tooth, here in particular the second stop tooth 54B, just under the body of the second push-button 5B. It can thus be understood how by actuating the push-buttons, and in particular the second push-button 5B, inwards, one can simultaneously trigger the unlocking and the adjustment operation in a simple, efficient and intuitive manner.
  • FIG. 4C shows the interior of the return means 6, and in particular the arrangement of the first elastic element 61 and of the second elastic element.
  • this figure clearly highlights the fusion of the various functional parts mentioned above, namely the control member 5, the locking element 53 and the stop element 54, made by a single and same structural part, namely a push button, a tine and a retractable hook.
  • the duplication of each of these structural elements makes it possible to further increase the comfort of use by using a particularly intuitive operation.
  • this figure also shows how the guiding of the two push-buttons is carried out in translation along a radial direction, perpendicular to the longitudinal direction L of the clasp 100 (corresponding to that of the cover 7), thanks to the use of two elements separate recall elastics.
  • the fact that the outer casing of both the first push-button 5A and the second push-button 5B is in contact with respect to the internal surface of each side opening for insertion provided in the side walls 74 of the combined cover to this arrangement of a mutual connection via two split elastic return elements makes any tilting movement of the pushers impossible and confines their movement to a single translation towards the inside of the cover.
  • the shape of the side walls of the internal bulge 711 which are partially cylindrical, additionally form at least in part an internal bearing surface for the elastic return means 6, when they consist of first and second elastic elements 61 and 62 respectively cylindrical, and therefore further strengthens the conferred slide structure.
  • the figures 5A and 5B differ in that the figure 5A illustrates a case where the control member 5 is at rest (rest position Pr) while the figure 5B illustrates a case where the control member 5 is in the active position Pa, that is to say where the first push-button 5A and the second push-button 5B are pressed and consequently the stop teeth 54A, 54B integral with each of these push-buttons 5A, 5B are released from the toothing of the rack 42A, 42B which is associated with them, here in particular the second tooth 54B of the corresponding notch of the second lateral toothing 42B of the rack 4.
  • FIG. 5A and 5B illustrates the inside of the cover 7 according to the same view as the Figures 4A-4C previous ones, and the only thing that has been added to these new latest figures compared to the previous ones mainly concerns the sliding connecting element 4 as well as the associated rack mechanism.
  • this sliding connecting element 4 is connected in an articulated manner to a first end 21 of the first branch 2, itself connected to the first leg 3A and second leg 3B of the stretcher forming the second branch 3 of the clasp via the hinge pin 23, as illustrated on the left of these figures.
  • the oblique surface O of the notches 420 of the rack which had not been referenced on the figure 2A And 2B for some questions of readability, and oriented towards the inside going from right to left in the figure, which means that it is possible to push the sliding connecting element 4 from its "exit" position from the first internal compartment 71 of the cover 7 towards the bottom of this same compartment to the right, up to the demarcation line materializing the delimitation vis-à-vis the second internal compartment 72.
  • a shortening of the length of the bracelet is possible without pressing the buttons - pushers 5A, 5B.
  • each of the notches of the lateral toothings of the rack namely the first notches 420A of the first lateral toothing 42A and the second notches 420B of the second lateral toothing 42B have, in addition to the oblique surface O, a surface S perpendicular to the longitudinal direction of the clasp, making any jump backwards impossible.
  • Such a mechanism is therefore in no way liable to cause any involuntary lengthening of the length of the bracelet.
  • the extension of the surfaces S and O of the notches has been shown in dotted lines on each of these figures.
  • the maximum adjustment stroke C which is preferably between 5 and 8 millimeters, is indicated on the figure 5B as corresponding to the difference in length of the strap between the first adjustment position P1 and the second adjustment position P2.
  • the present invention describes a new clasp with a folding clasp of simple and refined construction particularly suitable for a diver's watch with regard to the additional mechanism for extending the length of the bracelet which can be easily concealed in addition to that of the fine adjustment of the length under clasp cover.
  • the adjustment device proposed can be easily integrated in a modular fashion into an existing folding clasp solution, and what is more in a particularly aesthetic way by concealing it entirely under a removable cover.
  • This variant also has the additional advantage of facilitating after-sales service by making it easier to replace spare parts of the clasp.
