    Technical area
    The present invention relates to the field of watchmaking and jewelery. It relates, in particular, foldable clasps for bracelets, especially for watch straps.
    State of the art
    Are known from the prior art a large number of types and types of foldable bracelet clasps, which are likely to change between a folded state around the wearer's wrist, and an unfolded state, to increase the diameter of the bracelet to easily pass the wrist of the wearer. These clasps typically comprise two or three elements hinged to one another and a locking device to maintain the clasp in folded state, and they exist not only for rigid bracelets made of rigid links, for example metal, but also for traditional so-called leather, fabric or plastic bracelets. Several types of clasps are suitable at the same time for both types, namely rigid bracelets and soft bracelets.
    EP 0 648 444 and BE 494 180 disclose clasps for traditional leather bracelets, in which the adjustment of the length of the bracelet is done by inserting a barb in a hole selected from several holes provided along a strands. These clasps are not ideal for the comfort of the wearer.
    For bracelets with strands of fixed length, the adjustment of the length of the bracelet is typically at the clasp, providing several possible attachment points (see for example document CH 497 151), or providing a system for adjusting the length of a portion of the clasp, as is the case in documents CH 669 501 and EP 0 467 120.
    Moreover, all these types of bracelet have the disadvantage that it is difficult to adjust the length of the bracelet if it becomes tight around the wrist of the wearer, for example because of exercise or temperature high ambient.
    In order to remedy this problem, elastic devices provided inside the clasp have been proposed, among others, in US 2,408,279, GB 936,697 and US 1,827,243. Nevertheless, these arrangements are not very compact. , and are relatively difficult to implement.
    [0007] All the clasps mentioned above are optimized for relatively inexpensive manufacture, using as much stamped sheet metal as possible, which is not suitable for a high-end application.
    The object of the invention is, therefore, to provide a modular timepiece in which the aforementioned defects are at least partially overcome.
    Disclosure of the invention
    More specifically, in the first place the invention relates to a bracelet clasp comprising a base element arranged to be connected to a first end to a first strand of a bracelet, an intermediate element articulated on the element of base at a second end thereof, and a terminal member hinged to the intermediate member at one end thereof, the end member being arranged to receive a second strand of strap and to allow adjustment of the length of the latter strand to form a loop element.
    The clasp further comprises a locking system arranged to lock the clasp in a folded position and comprising actuators arranged to unlock the locking system to allow the clasp to move to an unfolded position.
    According to the invention, the base element comprises a convex section and a concave section, the concave section being adapted to receive at least a portion of the terminal element when the clasp is in its folded position.
    This arrangement of convex and concave sections gives the clasp good comfort, good compactness and strength of construction, which is suitable for high-end use.
    Advantageously, the intermediate element has a convex section corresponding to that of the base element and a concave section corresponding to that of the base element, so that, in the folded position of the clasp, the base element and the intermediate element interlock one inside the other. Compactness is therefore improved.
    Advantageously, the locking system comprises a fixed part, such as a notch, and a retractable part, such as a movable hook, one of these parts lying on the base element, the other on the terminal element. Preferably, said fixed portion is located on the base member and said retractable portion and the actuators are located on the end member. A minimum thickness of the base element and the intermediate element is therefore possible.
    Advantageously, the end portion comprises a fixed barb extending from a bridge and a pair of wings of a loop located on either side of the barb so that said second strand can pass between the wings and the bridge, the barb cooperating with a hole provided in the strand. The strand is well guided and supported in the terminal part. Still advantageously, said wings are connected to the bridge by lateral connecting elements, which still assist in positioning and supporting the strand.
    Secondly, the invention relates to a bracelet clasp comprising a base element arranged to be connected to a first end to a first strand of a bracelet and a terminal element articulated directly or indirectly (that is, with or without an intermediate element) on the base element at one end of the latter, the end element being arranged to be connected to one end of a second strand of bracelet.
    The clasp also comprises a locking system arranged to lock the clasp in a folded position and comprising actuating members, such as pushers, arranged to unlock the locking system to allow the clasp to evolve to a closed position. unfolded position.
    The locking system comprises, located in one of the base element or the terminal element, a groove, at least one slide housed in said groove and being arranged to slide along a sliding axis, and a pusher secured to said slider.
    According to the invention, the pusher comprises a support zone of elongate shape in a direction perpendicular to the sliding axis, said pusher being secured to said slide by clipping. In doing so, no screw, rivet or the like is necessary to secure the support zone to the slide; this results in a particularly clean appearance. Furthermore, because the support zone is elongated, it can be used as a cache for, for example, a possible screw or the like provided in the element underlying the bearing zone.
    Advantageously, the other of the base element or the terminal element comprises a locking element, such as a groove, arranged to cooperate with a complementary locking element, such as a lug, provided on said slider.
    Advantageously, the pusher comprises at least one tongue extending parallel to said sliding axis, the tongue comprising a hook cooperating with a complementary notch provided in said slider.
    Advantageously, said slider is provided in a bridge extending between lateral elements of said base element or terminal element, if any, said bridge being secured to said lateral elements by fastening members, said fasteners fastener being hidden by said pusher, to provide a very clean appearance to the clasp.
    Advantageously, the slide and the pushers are integrated in said terminal element of the clasp.
    Thirdly, the invention relates to a bracelet clasp comprising a base element arranged to be connected at a first end to a first strand of a bracelet, a terminal element articulated directly or indirectly on the base element. at one end of the latter, the terminal element being arranged to receive a second bracelet strand, and comprising a hollow cover, and a fastening element housed in said cover and adapted to be connected to an end of a second strand of bracelet.
    According to the invention, the fastening element is locked inside the cover by means of at least one locking screw located in a threaded hole that comprises the fastening element, the end of said locking screw taking place in one of a plurality of notches provided in an inner surface of the lid.
    This solid attachment between the fastener element and the lid does not require any visible element from outside the clasp (such as a screw, a hole, a slot ...) when the bracelet is worn, this which gives the clasp a very clean appearance.
    Advantageously, the cover comprises a solid outer portion, two side walls, and two rails extending inwardly of the cover from the side walls, along at least a portion of these side walls. Said plurality of notches is on an inner surface of said solid outer portion. This construction allows easy machining, resulting in a strong but lightweight lid.
    Advantageously, the fastening element is arranged such that it can slide inside the cover when said locking screw is not tight, which allows easy adjustment of the length of the bracelet.
    Fourthly, the invention relates to a bracelet clasp comprising a base element arranged to be connected at a first end to a first strand of a bracelet, a terminal element articulated directly or indirectly on the element of base at one end thereof, the end member being arranged to receive a second strand of bracelet, and comprising a hollow cover.
    An attachment member is housed in said cover and is adapted to be connected to one end of a second bracelet strand and locked inside the cover.
    The attachment element comprises a first sub-element integral with said cover, a second sub-element comprising an attachment point arranged to be connected to said second strand of the bracelet, and at least one elastic element arranged between said sub-elements. elements such that the fastening element can evolve from a retracted state to an elongate state against said elastic member, and vice versa.
    According to the invention, each sub-element is stirrup-shaped, the two sub-elements being opposite and nested one inside the other in order to slide on one another. A very compact attachment element allowing an automatic extension of the length of the bracelet is thus proposed. This attachment element can, for example, take place in the cover mentioned above, or alternatively could be integrated with another existing clasp.
    Advantageously, each sub-element comprises a transverse portion linking a pair of longitudinal legs ending in lugs. Each transverse portion may have a first thickness, said lugs also having the same thickness as the transverse portions, and the legs having thicknesses whose sum is substantially equal to said first thickness, which gives a very compact elastic element.
    [0034] Advantageously, the lugs of said second sub-element comprise at least one attachment point for a strand of the bracelet, which is a particularly simple and compact solution.
    Advantageously, one of the sub-elements comprises at least one hole oriented parallel to the legs of the same sub-element, in which the elastic element is housed. The attachment member further comprises a tube associated with each elastic member, said tube having a closed end in contact with the transverse portion of the other sub-member, its open end penetrating into said corresponding hole to serve as a that guide-spring. A simple and compact arrangement of one or more elastic elements, in particular coil springs, is thus proposed.

    Embodiments of the invention
    Figs. 1a-1c illustrates a first clasp 1 according to the invention in its unfolded position, and FIGS. 2a - 2d shows it in its folded position.
    The clasp 1 comprises an elongate base member 3, which is intended to take place against the wrist 2 of the wearer. The base member 3 comprises, at a first end, an attachment point 5 for attaching a first bracelet strand 7a, and at its second end it is hinged to an intermediate member 8 by means of a hinge 9. In the illustrated example, the base member 3 comprises two parallel arms between which at least partially overlaps the intermediate element 8 in the folded position, but a reverse configuration is also possible. The shape of the intermediate element 8 is thus complementary to that of the base element 3 so that it fits into the latter. Furthermore, the base member 3 comprises a base plate 3b connecting the arms 9 on the wrist side over at least a part of their length.
    The intermediate element 8 is articulated at a first end to the articulation 9, and is articulated to a terminal element 12 at a second end via a further articulation 11. This terminal element 12 forms an element loop, and as such includes a barb 15 secured to a pinch portion 13b of a bridge 13 of the terminal member 12 and extending from said bridge 13. The pin portion 13a is formed in as rail that engages in the other part of the bridge 13, as is best seen in FIG. 8a, which represents the terminal element 12 in exploded view. The terminal element 12 further comprises a pair of wings 17 each connected to the bridge 13 of the terminal element 12 by V-shaped lateral connection elements 19, said flanges 17 extending at the ends of the connecting elements. The bridge 13 is secured to the lateral connecting elements 19 by screws 20 or by any other suitable fastening member (rivet, pin or the like, or even welding, brazing or the like), as visible on fig. 1a and 2a in which the pushers 29 (see below) have been removed to show the screws 20. The wings 17 and the lateral connecting elements 19 are arranged to support a second bracelet strand 7b which takes place in the terminal member with the barb 15 passing through a hole formed in said second bracelet strand 7b. As clearly visible in figs. 1a and 2a, the second strand 7b passes beneath the wings 17 and above the bridge 13 of the end element 12, between the lateral connecting elements 19.
    In order to give the clasp 1 a compact structure and comfortable to wear, the base element and the intermediate element each comprise a concave portion 3a, 8a, so that the terminal element 12 has a lower profile possible in the folded position of the clasp 1. These concave portions 3a, 8a are concave, or hollow, considered from the point of view of the end element 12 in the folded position of the clasp 1. Between each of the concave portions 3a, 8a and the hinge 9, the base element 3 and the intermediate element 8 are convex in the folded position, seen from the outside, in order to be concave on the wrist side.
    In this construction, the free end of the second strand 7b remains outside, which increases the comfort for the wearer.
    In order to maintain the clasp 1 in the folded position, a locking system is provided, which is illustrated in detail in FIGS. 3a - 3f as well as FIGS. 8a and 8b. This system comprises fixed grooves 21 provided in each of the inner walls of the arms of the base element 3. The terminal element 12 comprises, in its bridge 13, a pair of sliders 23 which slide inside a groove 13a provided in the bridge 13. A spring exerts a force tending to push the sliders 23 outwardly.
    Each of the sliders 23 comprises a movable pin 27 extending perpendicular to the axis of movement of the sliders 23, that is to say towards the base member in the folded position, and have shapes complementary to the grooves 21 provided in the base member to cooperate with the lugs 27. The positions of the lugs 27 and grooves 21 can be reversed.
    So that the intermediate portion 8 does not block the pins 27, it comprises a thinned portion 8b so that the lugs 27 can pass next to it and can reach the grooves 21.
    In order to actuate the sliders 23, pushers 29 constituting actuating members are provided extending outwardly of the terminal element 12.
    The pushers 29 have a bearing zone 29a of elongated shape and a pair of elastic tongues 29d each ending with a hook 29c extending outwardly. The invisible surface of the pusher 29 includes cutouts 29b to allow the heads of the screws 20 to enter the pusher 29 when the user presses the latter. The tabs 29d enter an opening provided in the sliders 23 and the hooks 29c cooperate with complementary grooves 23a provided at the bottom of these openings. In this way, the pushers 29 are clipped into the sliders 23 and are not removable. Furthermore, the elongate shape of the bearing areas serve as a cover for the screws 20, and therefore, seen from the outside, no assembly means is visible. This aspect is clearly visible on the section along the axis A-A of FIG. 8b, which clearly shows the interrelation between the screws 20 and the pusher 29.
    The pushers 29 take place in a housing 31 provided on the outer face in the middle of the lateral connecting elements 19, and therefore have an improved aesthetics.
    This locking system generally applies not only to the clasp 1 of Figs. 1 to 3, even a simple clasp with two articulated elements, or a clasp with three symmetrical elements. Moreover, it is possible to reverse the arrangement by arranging the slides, pushers etc. in the base element and the grooves in the terminal element.
    A great advantage of this kind of locking system is that no screws, slits or other aesthetically undesirable elements are visible from outside the clasp. The appearance of the clasp is very clean to the eye.
    Figs. 4a and 4b illustrate another variant of a bracelet clasp 1 in the folded position, and FIGS. 5a and 5b illustrate this same clasp in unfolded position. Moreover, FIG. 9 illustrates the end portion 12 of this clasp in exploded view.
    In a similar manner to the clasp 1 of FIGS. 1 to 3, it comprises an elongate base element 3, which is intended to take place against the wrist 2 of the wearer. The base member 3 comprises, at a first end, an attachment point 5 for attaching a first bracelet strand, and at its second end it is hinged to an intermediate member 8 via a hinge 9.
    In the example shown, the base member 3 comprises two parallel arms, between which the intermediate element 8 is engaged in the folded position, but an inverse configuration is also possible. The shape of the intermediate element 8 is thus complementary to that of the base element 3 so that it fits into the latter. Furthermore, the base member 3 comprises a base plate 3b connecting the arms 9 on the wrist side over at least a part of their length.
    The intermediate element 8 is articulated at a first end to the hinge 9, and is articulated to a bridge 13 of a terminal element 12 at a second end via a further hinge 11.
    The terminal element 12 also comprises a cover 40, which is shown in more detail in FIGS. 4c, 4d and 9. The lid 40 consists of a hollow body comprising a curved outer portion 40a, two side walls 40b and two inwardly extending rails 40c formed from the side walls 40b whose ends are bent inwardly, along at least a portion of these side walls 40b and so as to be parallel to said outer portion 40a. In the illustrated example, the rails 40c are independent of one another, but it is also possible that they are joined to each other by means of bridges, while leaving access to the screws blocking 42, 46 (see below).
    The bridge 13 of the end portion 12 enters the hollow space between the outer portion 40a and the rails 40c of the cover 40, and is locked in position by means of a locking screw 42 whose end takes place in a corresponding notch 40d provided in the inner surface of the curved outer member 40a. Alternatively, the locking screw 42 may be replaced by a rivet, a shaft driven into the lid, or the like.
    A locking system which is substantially identical to that illustrated in FIGS. 1 to 3 is also provided, the main difference being the absence of lateral fasteners connecting the bridge to the side portions of the end portion 12. Since the locking screw 42 blocks the bridge 13 in the cover 40, such organs are superfluous. So that the pushers 29 can penetrate through the side walls of the cover 40, corresponding slots 40e are provided. Otherwise, the locking system is identical to that described above, and should not be described again here.
    In order to attach the end portion to the other strand of the bracelet, a fastening element 44 comprising an attachment point 48 for the strand of the bracelet is provided inside the cover 40. This element of fastener 44 takes place, in the same way as the bridge 13, in the hollow space between the outer member 40a and the rails 40c of the cover 40. The fastener element is also locked in position by means of a screw 46, which interacts with one of a plurality of notches 40f provided in the inner surface of the outer portion 40a of the cover 40. The length of the strap can therefore be adjusted by unscrewing the locking screw 46 to allow attachment member to slide inside the cover 40, then tightening the locking screw 46 in the notch 40f corresponding to the desired length.
    It goes without saying that the fastening element also applies to any other clasp comprising a hollow cover, and is independent of other characteristics of the clasps described here (number of elements constituting the clasp, exact shape of the elements etc.)
    The attachment element 44 also incorporates an elastic system to allow the bracelet to stretch in response to traction, to prevent the bracelet from becoming too tight if the wrist of the user expands in response to elevated temperature, physical activity, or the like. Figs. 6a-c illustrate the fastening element 44 in its rest position, FIG. 6d illustrates it in exploded view, and figs. 7a - c illustrates it in its extended position.
    The fastening element 44 is constructed of two sub-elements 44a, 44b, in the form of opposed stirrups, nested spit heads into one another, each comprising a transverse portion linking a pair of longitudinal legs. which has a thickness e1 of about half that of the corresponding transverse portion e2. It goes without saying that it is possible that the legs of each sub-element may have different thicknesses, the sum of which ideally corresponds to substantially the thickness of the transverse parts. Each leg ends with a pin-shaped foot that has substantially the same thickness as the cross section. Variations of the thickness ratios are also conceivable.
    The first sub-element 44a comprises in the transverse portion a threaded hole 46a for the passage of the biocage screw 46 mentioned above. This sub-element 44a is thus anchored to the cover 40.
    The second sub-element 44b comprises integrated pins forming feet, the second attachment point 48 of a strand of the bracelet.
    In order to tender to separate the sub-elements 44a, 44b and maintain them in their rest position, a pair of elastic elements 50, including helical springs guided by tubes 52 each comprising a closed end in contact with the transverse element of the second sub-element 44a and corresponding holes 50a provided in the transverse element of the first sub-element 44a are provided. The tubes 52 have a length sufficient for them to enter the corresponding holes 50a, to serve as a spring guide. Naturally, other arrangements of one or more elastic elements are possible. The resilient members 50 serve, therefore, to separate the cross members and to hold the fastener in a retracted state.
    In response to a force F exerted by the bracelet, your sub-elements 44a, 44b slide on one another thus compressing the elastic elements 50, until the transverse part of the second sub-element 44b comes into contact with that of the first sub-element 44a (Fig. 7a-c). The fastener element is then in an elongated state, and the length of the bracelet is therefore at its maximum.
    Once the force F is no longer sufficient to overcome the force exerted by the elastic elements, the fastening element returns to its initial state, shortened.
    It goes without saying that the manner in which the fastening element 44 is locked in the cover 40 to adjust the length of the bracelet is independent of the elastic system. Indeed, a fastening element 44 without elastic system is also possible. Such a fastening element 44 could be very simple, for example consisting of a parallelepipedal element provided with a threaded hole 46a for receiving the locking screw 46. Furthermore, a fastening element 44 comprising an elastic system which is not adjustable is also conceivable.
    Moreover, these kinds of arrangements of the fastening element and the elastic element do not require any screw, slot or other undesired element that is visible from outside the clasp. The appearance of the clasp is very clean to the eye.
    All the embodiments mentioned above are particularly suitable for a machined solid construction, which gives them a strength and robustness that is particularly applicable to high-end clasps.
