Definitions
- the invention relates to a clasp for jewelry or wristwatch, comprising a stretcher with a first housing in which are moved against one another a first pusher and a second pusher on a first bearing surface to against elastic return means, said first pusher and said second pusher being held in said first housing by at least one closure plate that can occupy a closed position in a second housing.
- the invention also relates to a bracelet comprising at least one such clasp.
- the invention also relates to a wristwatch comprising such a bracelet.
- the invention relates to the fields of watchmaking, jewelery, and jewelery, and more particularly wristwatches and bracelets.
- clasps are used in watchmaking and jewelery, to allow the opening and closing of a bracelet, especially a watch. These clasps bring closer the strands of the bracelet and maintain them in the joined position corresponding to the closure as such.
- the strands of the bracelet are articulated at the end of arms locking leaflets, themselves articulated at the ends of a stretcher which has locking means complementary to those of the folding arms. Unlocking of the arms can be effected by force or, advantageously, by means of pushing elements.
- these clasps have pushers movable in the opposite direction to the stretcher, against the compression of an element to lock or unlock the folding arm when closing or opening the clasp.
- the document FR2825244 discloses a folding pusher strap clasp comprising a generally H-shaped profiled stretcher which has arrangements for mounting two opposing pushers and the arrangement for a spring-blade biasing member which allows movement pushers.
- a backing plate holds the pushers, the spring blade and the attachment system against the stretcher for the opening and closing of the clasp.
- the same H-shaped support plate has symmetrically two indentations delimited by parallel branches for mounting arms having opposite the hinge portion, arrangements for the articulated mounting of a portion of the bracelet.

Description
L'invention concerne un fermoir pour bijou ou montre-bracelet, comportant un brancard avec un premier logement dans lequel sont mobiles à l'encontre l'un de l'autre un premier poussoir et un deuxième poussoir sur une première surface d'appui à l'encontre de moyens de rappel élastique, ledit premier poussoir et ledit deuxième poussoir étant maintenus dans ledit premier logement par au moins une plaque de fermeture pouvant occuper une position de fermeture dans un deuxième logement.The invention relates to a clasp for jewelry or wristwatch, comprising a stretcher with a first housing in which are moved against one another a first pusher and a second pusher on a first bearing surface to against elastic return means, said first pusher and said second pusher being held in said first housing by at least one closure plate that can occupy a closed position in a second housing.
L'invention concerne encore un bracelet comportant au moins un tel fermoir.The invention also relates to a bracelet comprising at least one such clasp.
L'invention concerne encore une montre-bracelet comportant un tel bracelet.The invention also relates to a wristwatch comprising such a bracelet.
L'invention concerne les domaines de l'horlogerie, de la bijouterie, et de la joaillerie, et plus particulièrement des montres-bracelets et des bracelets.The invention relates to the fields of watchmaking, jewelery, and jewelery, and more particularly wristwatches and bracelets.
De nombreuses variantes de fermoirs sont utilisés dans l'horlogerie et la bijouterie, pour permettre l'ouverture et la fermeture d'un bracelet, notamment de montre. Ces fermoirs permettent de rapprocher les brins du bracelet et de les maintenir en position jointive correspondant à la fermeture en tant que telle. Généralement, les brins du bracelet sont articulés en bout de bras dépliants de verrouillage, eux-mêmes articulés aux extrémités d'un brancard qui présente des moyens de verrouillage complémentaires de ceux des bras dépliants. Le déverrouillage des bras peut s'effectuer à force ou, d'une manière avantageuse, aux moyens d'éléments poussoirs. En général, ces fermoirs ont des poussoirs mobiles en sens contraire par rapport au brancard, à l'encontre de la compression d'un élément de rappel, pour verrouiller ou déverrouiller le bras dépliant lors de la fermeture ou de l'ouverture du fermoir.Many variants of clasps are used in watchmaking and jewelery, to allow the opening and closing of a bracelet, especially a watch. These clasps bring closer the strands of the bracelet and maintain them in the joined position corresponding to the closure as such. Generally, the strands of the bracelet are articulated at the end of arms locking leaflets, themselves articulated at the ends of a stretcher which has locking means complementary to those of the folding arms. Unlocking of the arms can be effected by force or, advantageously, by means of pushing elements. In general, these clasps have pushers movable in the opposite direction to the stretcher, against the compression of an element to lock or unlock the folding arm when closing or opening the clasp.

Dans ces fermoirs connus, chaque poussoir se déplace avec un certain jeu par rapport à la section de déplacement formée par les parois du brancard et la plaque d'appui. L'addition des jeux de déplacement de l'un et de l'autre poussoir peut conduire à une prise incomplète des moyens de verrouillage, notamment des crochets ou des rainures, du bras dépliant, par rapport aux moyens de verrouillage complémentaire, notamment des rainures ou respectivement des crochets, de l'un ou l'autre poussoir, la géométrie de la plaque d'appui ayant une grande importance. On ne peut alors tout à fait exclure un déverrouillage intempestif et une ouverture du fermoir, pouvant provoquer la perte de la montre-bracelet, ce qui n'est pas admissible pour des montres de haut de gamme.In these known clasps, each pusher moves with a certain clearance with respect to the displacement section formed by the walls of the stretcher and the support plate. The addition of the displacement sets of one and the other push may lead to an incomplete grip of the locking means, in particular hooks or grooves, of the folding arm, relative to the complementary locking means, in particular grooves or hooks, one or the other pusher, the geometry of the support plate having a great importance. One can then quite exclude inadvertent unlocking and opening the clasp, which can cause the loss of the wristwatch, which is not eligible for high-end watches.
La difficulté de fabrication commune à ces inventions connues consiste dans la minimisation du jeu entre les poussoirs, ce qui exige une fabrication avec des tolérances étroites, donc coûteuse, tout en requérant la qualité d'aspect et l'esthétique qui caractérisent les montres-bracelets de luxe ou les bijoux.The common manufacturing difficulty to these known inventions consists in minimizing the clearance between the pushers, which requires manufacturing with close tolerances, therefore expensive, while requiring the quality of appearance and aesthetics that characterize the wristwatches. luxury or jewelry.

Il existe donc un besoin pour un fermoir amélioré, évitant la prise de jeu entre les boutons poussoirs, et améliorant le système d'ouverture et fermeture du fermoir.There is therefore a need for an improved clasp, avoiding the play between the push buttons, and improving the opening and closing system of the clasp.
La recherche d'une configuration plus simple doit faciliter la fabrication des différentes pièces de petite dimension, et en particulier par l'utilisation de moyens de soutien et d'accrochage plus simples et moins coûteux que les vis de précision.The search for a simpler configuration should facilitate the manufacture of various small parts, and in particular by the use of support and attachment means simpler and less expensive than precision screws.
A cet effet, l'invention concerne un fermoir pour bijou ou montre-bracelet, comportant un brancard avec un premier logement dans lequel sont mobiles à l'encontre l'un de l'autre un premier poussoir et un deuxième poussoir sur une première surface d'appui à l'encontre de moyens de rappel élastique, ledit premier poussoir et ledit deuxième poussoir étant maintenus dans ledit premier logement par au moins une plaque de fermeture pouvant occuper une position de fermeture dans un deuxième logement, caractérisé en ce que ledit fermoir comporte au moins un élément de blocage élastique de ladite plaque de fermeture, ledit élément de blocage élastique comportant un bouton-poussoir et étant maintenu dans ledit brancard et agencé pour, d'une part dans une position comprimée autoriser le mouvement de ladite au moins une plaque de fermeture et, d'autre part, dans une position détendue immobiliser ladite au moins une plaque de fermeture dans ladite position de fermeture par coopération dudit bouton-poussoir avec un quatrième logement que comporte ladite au moins une plaque de fermeture.For this purpose, the invention relates to a clasp for jewel or wristwatch, comprising a stretcher with a first housing in which are moved against one another a first pusher and a second pusher on a first surface bearing against elastic return means, said first pusher and said second pusher being held in said first housing by at least one closure plate that can occupy a closed position in a second housing, characterized in that said clasp comprises at least one elastic blocking element of said closure plate, said elastic blocking element comprising a push button and being held in said stretcher and arranged for, firstly in a compressed position allow the movement of said at least one closing plate and, secondly, in a relaxed position immobilizing said at least one closure plate in said closed position by coop ration of said push button with a fourth housing that comprises said at least one closure plate.

Le brancard profilé 1 comporte un premier logement 200, qui constitue une chambre dans laquelle le premier poussoir 6 et le deuxième poussoir 7 sont mobiles en glissement, sur au moins une première surface d'appui 300, notamment constituée par le fond du brancard 1, mais qui peut aussi comporter une ou plusieurs surfaces latérales, ou encore un guidage sur une tige ou sur un ressort, ou autre. Cette chambre est fermée d'un côté par le fond du brancard, et du côté opposé par les plaques de fermeture 8 et 9, et, en position fermée et verrouillée du fermoir, par les extrémités porteuses des chapes 5c des bras dépliants 5. Les trois logements de centrage 1b destinés à recevoir les éléments de blocage élastique 10 sont situés dans ce premier logement 200, lequel présente encore des zones 1a limitant la course des bras dépliants 5. Les deux paires de bras 2 prolongent le brancard profilé 1, et comportent, sur leur partie supérieure en bordure du premier logement 200, des logements en biseau 28, 29, femelles pour recevoir les biseaux mâles des becs 81 et 91 des plaques de retenue 8 et 9.The profiled stretcher 1 comprises a
Deux bras dépliants 5 sont reliés aux bras 2 par leur partie articulée 5a et deux goupilles lisses 4 qui forment les axes de rotation 2b. La partie externe de chaque bras dépliant 5 porte une chape 5c destinée à porter un brin 910 du bracelet 900.Two folding arms 5 are connected to the
Le brancard profilé 1 reçoit les deux poussoirs 6 et 7 avec les moyens de rappel élastique 40 constituant un leur système de compression de l'un contre l'autre, formé par deux ressorts 40. Les moyens de verrouillage 30 de ces poussoirs sont constitués par des crochets 306 et 307, situés à l'extrémité de branches 306a, 307a.The shaped stretcher 1 receives the two
Les poussoirs 6 et 7 sont maintenus dans le premier logement 200 du brancard 1, par les éléments de blocage élastique 10, insérés dans les logements de centrage 1b, et dans des lumières fermées 806, 807 situées dans les branches respectives 306a et 307a, les éléments de blocage élastique 10 constituant ainsi des moyens de limitation de course des poussoirs 6 et 7.The
Après le montage en position des poussoirs 6 et 7, des éléments de blocage élastique 10 et du ou des ressorts 40, les plaques de fermeture 8 et 9 sont présentées en zone médiane du brancard, puis glissées, selon la direction transversale T de mobilité des poussoirs 6 et 7, vers l'extérieur du brancard 1, leurs becs 81 et 91 sont insérés dans les logements en biseau latéraux 28 et 29 et poussés à l'encontre des éléments-ressort que comportent les éléments de blocage élastique 10, jusqu'à la mise en coïncidence des boutons-poussoirs 600 des avec les quatrièmes logements 700 respectifs, 80 et 90. Les plaques de retenue 8 et 9 sont alors immobilisées selon la direction transversale T, qui est ici perpendiculaire à la direction longitudinale L selon laquelle s'étendent les bras dépliants 5 et les brins 901 du bracelet 900, et les éléments de blocage élastique 10 sont eux aussi immobilisés en position. Du fait de la présence des boutons-poussoirs 600, un démontage inopiné des plaques de fermeture 8 et 9 n'est pas possible lors des manoeuvres courantes du fermoir 100, mais un démontage est possible en maintenance avec l'application un effort de pression d'un outil sur l'extrémité de l'bouton-poussoir 600 au travers d'un logement 80 ou 90.After the push-
L'accrochage et le verrouillage des bras dépliants 5 sur le brancard 1 est réalisé par coopération des crochets 306 et 307 des poussoirs 6 et 7 avec les moyens de verrouillage complémentaire 5d situés sur les côtés des bras dépliants 5. Lors de la pression des poussoirs 6 et 7 vers le centre du brancard 1, les crochets 306 et 307 sont écartés des moyens 5d, et les bras dépliants 5 sont alors libérés.The hooking and locking of the folding arms 5 on the stretcher 1 is achieved by cooperation of the
Les poussoirs 6 et 7 montrent des formes différentes. Le poussoir à simple accrochage 6 comporte une seule branche 306a, porteuse d'une lumière fermée 806 pour le guidage de l'élément de blocage élastique 10, et la réalisation de la butée mécanique de la partie de manoeuvre 206, et au bout de cette branche 306a un crochet 306, et comporte un logement 406a pour chaque ressort de compression 40, à l'intérieur d'une partie de manoeuvre 206 qui déborde du brancard profilé 1 pour pouvoir être pressée contre celui-ci par l'utilisateur. La partie de manoeuvre 206 présente une section réduite 206a pour son intégration au premier logement 200. Le poussoir à double accrochage 7 comporte deux branches 307a, porteuse chacune d'une lumière fermée 807 pour le guidage de l'élément de blocage élastique 10 correspondant, et au bout de ces branches 307a deux crochets 307, une partie de manoeuvre 207 analogue à celle du premier poussoir 6. La première plaque de fermeture 8 comporte un logement 80 unique pour coopérer avec l'élément de blocage élastique 10 situé du côté du premier poussoir à simple accrochage 6. La deuxième plaque de fermeture 9 comporte deux logements 90 pour coopérer chacun avec un élément de blocage élastique 10 situé du côté du deuxième poussoir à double accrochage 7.The
Les boutons-poussoirs 600 des éléments de blocage élastique 10 présentent un chanfrein particulier qui leur permet de s'emboîter par pression dans les logements 80 et 90. Ils sont de grande importance pour le maintien ferme et la stabilité des composants du fermoir 100 présenté. Selon la réalisation avantageuse de l'invention, leur fabrication est plus facile et moins coûteuse que celle des composants des fermoirs connus.The
L'invention procure un maintien ferme du fermoir 100, un fonctionnement à jeu minimal, et prévient tout déverrouillage intempestif.The invention provides a firm hold of the
