Le fermoir comporte au moins un organe de verrouillage agencé pour maintenir les organes de fixation du bracelet dans leur position fermée et au moins un organe de commande de l'organe de verrouillage agencé pour déverrouiller le fermoir en réponse à une action d'un utilisateur et passer de la position fermée à la position ouverte. En outre, le fermoir selon l'invention comporte un dispositif de réglage de la longueur utile du bracelet comprenant :
- un organe de réglage, portant le premier organe de fixation du bracelet, et
- au moins un verrou susceptible de présenter un état par défaut fermé, dans lequel l'organe de réglage est fixe, et un état ouvert, dans lequel l'organe de réglage est libre de coulisser dans la direction de la longueur du bracelet, en référence au second organe de fixation du bracelet, pour modifier la longueur utile du bracelet.
- an adjusting member, carrying the first fastening member of the bracelet, and
- at least one lock capable of presenting a closed default state, in which the adjustment member is fixed, and an open state, in which the adjustment member is free to slide in the direction of the length of the strap, with reference at the second fastening member of the bracelet, to modify the useful length of the bracelet.
La présente invention concerne également une montre-bracelet munie d'un tel fermoir.The present invention also relates to a wristwatch provided with such a clasp.
La problématique relative à la nécessité de prévoir un dispositif de réglage de la longueur utile d'un bracelet est bien connue.The problem of the need to provide a device for adjusting the useful length of a bracelet is well known.
D'une part, dans le cas de bracelets composés de maillon, il est possible que le poignet du porteur présente une circonférence dont la valeur est située entre deux configurations du bracelet différant l'une de l'autre d'un seul maillon. Cela est également le cas lorsqu'un bracelet en cuir caoutchouc ou analogues présente des perforations ne permettant pas un réglage suffisamment fin. Aussi, il est utile de prévoir un dispositif de réglage de la longueur utile du bracelet permettant un ajustement plus fin de la longueur du bracelet que le retrait ou l'ajout d'un maillon.On the one hand, in the case of bracelets composed of links, it is possible that the wrist of the wearer has a circumference whose value is located between two configurations of the bracelet differing from each other in a single link. This is also the case when a leather strap rubber or the like has perforations that do not allow a sufficiently fine adjustment. Also, it is useful to provide a device for adjusting the useful length of the bracelet allowing a finer adjustment of the length of the bracelet that the removal or addition of a link.
D'autre part, on sait également que la valeur de la circonférence du poignet varie en fonction des saisons, une valeur maximale étant généralement atteinte en été et une valeur minimale étant atteinte en hiver. Il est là encore préférable de prévoir un dispositif de réglage fin de la longueur utile du bracelet permettant au porteur du bracelet d'ajuster cette longueur pour améliorer le confort du bracelet au porter.On the other hand, it is also known that the value of the wrist circumference varies according to the seasons, a maximum value being generally reached in summer and a minimum value being reached in winter. It is also preferable to provide a fine adjustment device of the useful length of the bracelet allowing the wearer of the bracelet to adjust this length to improve the comfort of the bracelet to wear.
A titre d'exemple, la demande de brevet
Toutefois, l'ajustement de la longueur du bracelet correspondant est malaisé, en particulier parce qu'il ne peut être effectué sans l'utilisation d'un outil pointu. Non seulement, cette opération requiert une certaine dextérité mais, en outre, elle risque de conduire à des dommages au niveau du capot en cas de maladresse de la personne réalisant l'ajustement.However, the adjustment of the length of the corresponding bracelet is difficult, in particular because it can not be performed without the use of a sharp tool. Not only does this operation require dexterity but, in addition, it may lead to damage to the hood in case of awkwardness of the person performing the adjustment.
Pour éviter une telle situation, des dispositifs alternatifs ont déjà été divulgués, comme par exemple dans le brevet
Ainsi, le fermoir décrit dans ce brevet nécessite d'être ouvert pour procéder à l'ajustement de sa longueur.Thus, the clasp described in this patent requires to be opened to adjust its length.
On pourra signaler qu'un inconvénient qui en résulte est la perte du réglage de la longueur du bracelet à chaque ouverture du fermoir. De ce fait, le porteur du bracelet doit veiller à chaque fermeture de son fermoir que le crochet est inséré du côté de la portion centrale de la gâchette correspondant à la longueur souhaitée pour le bracelet.It may be noted that a disadvantage that results is the loss of adjustment of the length of the bracelet each opening of the clasp. As a result, the wearer of the bracelet must ensure each closure of his clasp that the hook is inserted on the side of the central portion of the trigger corresponding to the desired length for the bracelet.
Des dispositifs de réglage comportant un organe de verrouillage spécifique ont également été proposés, en alternative, pour éviter ce type d'inconvénients.Adjustment devices comprising a specific locking member have also been proposed, alternatively, to avoid this type of inconvenience.

Le document
Un but principal de la présente invention est de pallier les inconvénients des fermoirs connus de l'art antérieur, en proposant un fermoir de bracelet comprenant un dispositif de réglage de la longueur utile du bracelet de structure simple, proposant préférablement un réglage stable, y compris lorsque le fermoir est ouvert, et de manipulation aisée.A main object of the present invention is to overcome the drawbacks of known clasps of the prior art, by proposing a bracelet clasp comprising a device for adjusting the useful length of the bracelet of simple structure, preferably proposing a stable adjustment, including when the clasp is open, and easy handling.
A cet effet, la présente invention concerne un fermoir pour bracelet selon la revendication 1 annexée à la présente demande de brevet.For this purpose, the present invention relates to a bracelet clasp according to
Grâce à ces caractéristiques, le dispositif de réglage selon l'invention présente une structure discrète, puisqu'il est actionné par l'organe de commande déjà prévu pour déverrouiller le fermoir, bien qu'il soit distinct de l'organe de verrouillage du fermoir, ce qui permet en outre d'ajuster la longueur du bracelet même lorsque le fermoir est dans son état fermé.Thanks to these characteristics, the adjustment device according to the invention has a discrete structure, since it is actuated by the control member already provided to unlock the clasp, although it is distinct from the locking member of the clasp. , which further allows to adjust the length of the bracelet even when the clasp is in its closed state.
De manière générale, on peut avantageusement prévoir que le déverrouillage du fermoir est associé à un déplacement de l'organe de commande d'une première amplitude d1, le déverrouillage de l'organe de réglage par le verrou étant associé à un déplacement de l'organe de commande d'une seconde amplitude d2, d1 étant inférieur à d2.In general, it can advantageously be provided that the unlocking of the clasp is associated with a displacement of the control member by a first amplitude d1, the unlocking of the adjustment member by the lock being associated with a displacement of the control member of a second amplitude d2, d1 being less than d2.
Ainsi, il est possible de déverrouiller le fermoir sans déverrouiller l'organe de réglage, ce qui garantit le maintien du réglage souhaité lors de l'ouverture du fermoir, contrairement au fermoir de l'art antérieur décrit plus haut.Thus, it is possible to unlock the clasp without unlocking the adjustment member, which ensures the maintenance of the desired setting when opening the clasp, unlike the clasp of the prior art described above.
Par ailleurs, l'organe de réglage comporte préférablement un bâti portant le premier organe de fixation du bracelet et au moins un doigt agencé pour coopérer avec le verrou, ce dernier comportant une plaquette, adjacente au bâti et dans laquelle est ménagée une fente, suivant la direction longitudinale du bracelet. La fente présente au moins deux crans susceptibles de coopérer avec le doigt dans l'état fermé du verrou, pour définir deux longueurs utiles respectives différentes du bracelet, tandis que le doigt est susceptible de coulisser dans la fente dans l'état ouvert du verrou pour passer d'un cran à l'autre et modifier la longueur utile du bracelet.Furthermore, the adjustment member preferably comprises a frame carrying the first fastening member of the bracelet and at least one finger arranged to cooperate with the lock, the latter comprising a plate, adjacent to the frame and in which is formed a slot, following the longitudinal direction of the bracelet. The slot has at least two notches capable of cooperating with the finger in the closed state of the lock, to define two different respective useful lengths of the bracelet, whereas the finger is capable of sliding in the slot in the open state of the lock for move from one notch to another and change the useful length of the bracelet.
Selon une variante de réalisation préférée, le bâti comprend des parois supérieure et inférieure entre lesquelles est agencée la plaquette, le doigt présentant la forme d'une vis rendant solidaires entre elles les parois supérieure et inférieure.According to a preferred embodiment, the frame comprises upper and lower walls between which is arranged the wafer, the finger having the form of a screw making integral with the upper and lower walls.
On peut prévoir en outre que la paroi supérieure est formée par un capot comprenant une surface supérieure portant des parois latérales présentant
deux trous destinés à loger les extrémités d'une barrette de fixation d'un brin de bracelet, et
au moins une surface d'appui contre laquelle la paroi inférieure est maintenue au moyen de la vis.It can further be provided that the upper wall is formed by a cover comprising an upper surface carrying side walls having
two holes for housing the ends of a bar of a bracelet strand, and
at least one bearing surface against which the lower wall is held by means of the screw.
On peut également prévoir que l'organe de commande comprend un poussoir susceptible d'être déplacé suivant une direction sensiblement perpendiculaire à la direction longitudinale du bracelet, en réponse à une action de l'utilisateur, et que ledit poussoir (213) est indépendant dudit verrou (212).It can also be provided that the control member comprises a pusher capable of being displaced in a direction substantially perpendicular to the longitudinal direction of the bracelet, in response to an action by the user, and that said pusher (213) is independent of said lock (212).
De manière générale, on peut prévoir que le fermoir comporte un organe de commande supplémentaire, les organes de commande étant similaires et symétriques en référence à la direction longitudinale du bracelet et, que le dispositif de réglage comporte
un verrou supplémentaire associé à l'organe de commande supplémentaire, les verrous étant similaires et symétriques en référence à la direction longitudinale du bracelet, et
un doigt supplémentaire associé au verrou supplémentaire.In general, it can be provided that the clasp comprises an additional control member, the control members being similar and symmetrical with reference to the longitudinal direction of the bracelet and that the adjustment device comprises
an additional lock associated with the additional control member, the locks being similar and symmetrical with reference to the longitudinal direction of the bracelet, and
an extra finger associated with the additional lock.
Selon un mode de réalisation préféré, le fermoir est du type à boucle déployante comportant au moins deux lames articulées entre elles, dont une première lame comprend deux montants, symétriques en référence à la direction longitudinale du bracelet, insérés dans un évidement complémentaire de la seconde lame pour placer le fermoir dans sa position fermée, par rapprochement momentané des montants contre des moyens de rappel élastiques, le bord latéral extérieur de chacun des montants coopérant avec le bord intérieur correspondant de l'évidement pour définir un organe de verrouillage du fermoir. On peut alors avantageusement prévoir que chacun desdits montants porte l'un desdits verrous, et que lesdits poussoirs sont en appui contre les verrous et sont engagés à coulissement à travers des ouvertures correspondantes ménagées dans les parois latérales du capot et dans lesquelles ils sont retenus par des rebords qui s'étendent de part et d'autre des poussoirs
De manière générale, on peut également prévoir que le dispositif de réglage comprend au moins un organe élastique exerçant une force sur le ou les verrous tendant à le ou les maintenir dans son ou leur état fermé.According to a preferred embodiment, the clasp is of the folding clasp type comprising at least two blades hinged together, of which a first blade comprises two uprights, symmetrical with reference to the longitudinal direction of the bracelet, inserted in a recess complementary to the second blade for placing the clasp in its closed position, by momentarily bringing the uprights against elastic return means, the outer lateral edge of each of the uprights cooperating with the corresponding inner edge of the recess to define a locking member of the clasp. It can then be advantageously provided that each of said uprights carries one of said latches, and that said pushers bear against the latches and are slidably engaged through corresponding openings in the side walls of the hood and in which they are retained by edges that extend on both sides of the pushers
In general, it can also be provided that the adjusting device comprises at least one elastic member exerting a force on the locks or tending to maintain or in its closed state or.
Dans ce cas, le dispositif de réglage comprend préférablement un organe intermédiaire, de position fixe en référence au verrou et, présentant une surface d'appui pour une extrémité de l'organe élastique.In this case, the adjusting device preferably comprises an intermediate member, fixed position with reference to the latch and having a bearing surface for one end of the elastic member.
Le dispositif de réglage peut également comprendre un cliquet à bille associé à au moins deux creusures complémentaires et agencées pour indexer au moins deux configurations correspondant à deux longueurs utiles différentes du bracelet. Le cliquet à bille peut alors être porté par l'organe intermédiaire. Dans ce cas, les creusures peuvent être ménagées dans la paroi supérieure du dispositif de réglage.The adjusting device may also comprise a ball pawl associated with at least two complementary recesses and arranged to index at least two configurations corresponding to two different useful lengths of the bracelet. The ball pawl can then be carried by the intermediate member. In this case, the recesses can be formed in the upper wall of the adjustment device.
