Definitions
- the invention relates to a buckle type clasp. deployant for a bracelet, in particular for a bracelet watch, and more particularly such a clasp comprising at least one branch, at least one arm articulated by a first of its ends on a first end of said branch, said branch having a lateral face arranged opposite a lateral face of said arm in the closed position of the clasp, and locking means for lock the clasp in said closed position.
- the clasp includes two arms which are articulated on strands of the bracelet by one of their ends and on ends of two branches parallels of a central element in the form of a stretcher, by their other end.
- the central element has two notches of shape and size corresponding to those of the arms so that the arms are fully included in the notches in the closed position of the bracelet.
- the locking of the clasp in the closed position is provided by a notch system.
- the end of the arm which is attached to the strand has a beak one of the parts of which has a cooperating groove with a cylindrical member or bridge connecting the branches after it has been elastically engaged on the latter.
- This notching system has the disadvantage of being subject to rapid wear which results in the closure is no longer effectively guaranteed after a certain numbers of openings and closings.
- this clasp is relatively difficult to achieve precisely because it requires many mechanical operations, in particular rework machining after stamping of branches and arms, and adjustment of the beak with the bridge before mounting the clasp, in order to obtain a acceptable opening force and closing force.
- the main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a clasp of the folding mouth type, in particular for a watch strap or the like, including a reliable clasp locking system in its closed position and which, while imparting an improved aesthetics to the clasp as a whole, can be carried out in a simple and economical way.
- the invention relates to a clasp of the folding mouth type comprising at least one branch and at least one arm articulated by a first of its ends on a first end of said branch, said branch having a side face disposed opposite of a lateral face of said arm in the closed position of the clasp, and blocking means for blocking the clasp in said closed position,
- the locking means comprising at least one elastically deformable element which extends, in the closed position of the clasp, in a housing formed on the one hand by a longitudinal recess formed in said lateral face of said branch characterized in that on the other hand a longitudinal recess is formed in said side face of said arm.
- a clasp is obtained simple and economical structure and which has a constant closing force and opening force at over time, these can easily be controlled by adjusting the dimensions and / or the stiffness of the elastically deformable element whatever the nature of the material (s) used to make the other parts of the clasp.
- Figure 1 shows, in perspective, a first mode for making a clasp of the folding mouth type according to the invention and designated by the reference numeral general 1.
- the clasp 1 essentially comprises a base 2 and an arm 4. These elements are articulated one on the other by one of their ends and connected by their other end to first and second strands 6, 8 of a bracelet. Sections 6 and 8 partially shown in broken lines in the figure are attached to an object to wear, in particular a watch (not shown).
- the base 2 has the shape of an elongated thin blade, slightly curved lengthwise in order to adapt to the curvature of the wrist.
- Base 2 includes two parallel branches 10 and 12 connected together to each of their ends by connecting means 14 and 16 and delimiting between them a free space 18 longitudinal substantially rectangular.
- the connecting means 14 are formed by a tube whose end parts are fixed for example by welding on the upper surfaces 20 and 22 of a end of branches 10 and 12.
- the tube 14 is intended to receive a pin (not shown) around which the bracelet strand 8 is wound up and thus forms means for fixing the bracelet strand 8.
- the connecting means 16 located at the end of the branches 10 and 12 on which the arm 4 is articulated include a hinge.
- Figure 2 shows one way to make the hinge 16.
- a tube 24 provided with notches 26 is driven into an opening provided for this purpose in other ends of branches 10 and 12 and arm 4 pivots around the tube 24.
- Pins 28 provided each of a groove 30 are introduced into the tube 24 and are held in place there by notches 26 which penetrate into the grooves 30.
- Arm 4 for its part, is formed by an elongated blade which has the same thickness and has the same curvature longitudinal than those in base 2. Of general shape rectangular, its dimensions allow it to take place in the free space 18 of the base 2. At a end, arm 4 is crossed by a hole through which passes the notched tube 24 allowing the arm 4 to pivot around the tube 24.
- fixing means 32 for the second bracelet strand 16 also formed by a tube capable of receiving a pin (not shown) around which is wrapped the bracelet strand 6.
- the tube 32 is fixed for example by welding on an extreme part of the upper surface 34 arm 4.
- the tube 14 and the tube 32 are in particular suitable for fixing bracelet strands of the metal link type but it goes without saying that these fixing means can be easily modified by the skilled person to receive bracelet strands made for example of leather or similar.
- the arm 4 has a length slightly greater than the length of branches 10, 12 and includes in its upper surface 34 a transverse groove 36 formed for, in the position closed of the clasp, come in correspondence with the tube 14 and receive it. So when the clasp is in closed position, which appears in Figures 2 and 3 the arm 4 is included in the thickness of branches 10 and 12 at with the exception of tube 32 which emerges from the thickness of the clasp at the same level as the tube 14. It will be noted that in the embodiment described, the arm 4 must pivot in the direction of arrow F in Figure 1 to bring the clasp in its open position.
- the clasp 1 further comprises blocking means to lock the clasp, i.e. the arm 4 by relative to branches 10 and 12, in its closed position.
- the branches 10 and 12 each include a lateral face 36, in which a recess is formed longitudinal 40, 42.
- the arm 4 comprises two faces opposite sides 44, 46, each also being provided a longitudinal recess 48, 50.
- Each recess 40 and 42 of branches 10 and 12 is provided for, in position closed with the clasp, facing one of the recesses 48, 50 of the arm and thus form two longitudinal housings parallel 52, 54 (see fig. 3) in each of which extends an elastically deformable element 56, 58.
- Each elastically deformable element 56, 58 partially extends into each of the recesses forming its housing 52, 54 so that these elements 56, 58 lock the arm 4 on the arms 10, 12.
- the elements elastically deformable 56 and 58 each include a spring helical and the housings 52 and 54 have a substantially circular section.
- the clasp further comprises holding means of each elastically deformable element 56, 58 in a recesses forming its housing, in this case in the recesses 48 and 50 formed in the arm 4, so that it be retained in said recess when the clasp is in open position.
- the recesses 48, 50 open respectively in the lateral faces 36 and 38 of the arm 4 by openings delimited by two edges 60, 62 and 64, 66 separated by a distance less than the diameter of the springs 56 and 58.
- the longitudinal axis L of each of the springs 56, 58 is therefore contained in the recess 48, 50 who receives it.
- the recesses 48 and 50 extend, in section, on an arc greater than 180 ° and preferably on an arc of about 240 °.
- the recesses 40, 42 formed in the faces lateral branches 10, 12 they extend in section on an arc less than 90 ° and preferably equal at around 60 °.
- the recesses 40, 42, 48 and 50 can have different sections and by example, the section of the hollows 48, 50 which retain the elastically deformable element 56, 58 may be in dovetail or T-shaped, and the section of the hollows 40, 42 complementary can be in U or any other shape having a concavity making it possible to form a housing likely to receive the elements elastically deformable 56, 58.
- the diameter of the springs 56, 58 is slightly smaller than the diameter of the housings 52, 54 so that it there is a certain play between the springs 56, 58 and the housings 52, 54 and a fortiori, between the springs 56, 58 and the recesses 48, 50 in which they are maintained.
- the springs 56, 58 can thus deform without difficulty when opening and closing the clasp 1 as will be described below.
- the lateral faces 36 and 38 of the branches 10 and 12 respectively include ramps snap 68, 70 arranged in the parts lower of these faces. These ramps 68 and 70 extend respectively of the lower edges of the faces 36, 38 to the lower edges of the recesses 40, 42. These ramps 68, 70 allow the elements to be resiliently deformable to gradually deform during the closing the clasp as will appear more clearly in the following description.
- the clasp 1 also comprises stop means 72, 74 of the springs 56, 58 in the longitudinal direction in the recesses 48, 50.
- These stop means 72, 74 are formed by at least two contiguous end turns of the springs 56, 58 and whose diameter, when these springs are not mounted in the recesses 48, 50, is significantly higher than that of the housings 52, 54.
- the springs 56, 58 can be introduced easily in the corresponding hollow 48, 50 by their end having a diameter substantially smaller than that of the housing, the last turns 72, 74 forming the stop means in the recesses 48, 50 then being forced into these recesses 48, 50 to ensure a stop in the longitudinal direction of the springs 56, 58 in these past.
- the turns 72, 74 forming the stop means can respectively cooperate with annular grooves (not shown) formed in the recesses 48, 50.
- the operating principle of the clasp that comes to be described is as follows: during closure, the arm, when pushed in the direction of arrow F1, causes friction of the latching ramps 68, 70 branches 10, 12 on the parts of the springs 56, 58 which protrude out of the recesses 48, 50, which has for effect of elastically deforming the turns of the springs 56, 58 so that they are temporarily erased, until what these protruding parts of the springs 56, 58 gradually penetrate into the recesses 40, 42 complementary in branches 10, 12 and thus ensure a blocking of the arm 4 between the two branches 10, 12.
- the arm When opening, the arm is pushed in the direction arrow F and simultaneously requests all of the turns of the springs 56, 58 to deform them and release the arm 4. It results from the structure of the locking means that the force to be deployed to open the clasp is larger than that which is necessary for its closure, which gives the clasp greater comfort wearer and high security in closed position.
- closing forces and openness essentially depend on characteristics of the springs, so that they can be easily adjusted. To do this, just act on the characteristic parameters of each spring, to know the diameter of the wire and the number of turns of the spring.
- the welded tube 14 has been replaced by connecting means 14 of the type of those referenced in 16 in Figure 2 and in which a tube 15 acts as a spacer for maintain a suitable distance between branches 10 and 12 of the clasp.
- branches 10 and 12 are each extended beyond the connecting means 14 by 10 'and 12' branch parts.
- Each branch part 10 'and 12' includes an 11 'and 13' hole, the latter being arranged opposite one another and being intended to receive a pin (not shown) for fixing of a bracelet strand.
- the springs 56 and 58 are respectively stopped longitudinally in hollows 48 and 50 with a first of their ends, by the ends of a pin G1 driven out in a hole in branch 4, the two ends of the pin extending respectively in the recesses 48 and 50.
- element E comprises a U-shaped part with branches b, b 'extending respectively in the recesses 48 and 50 and are based against the second end of springs 56 and 58.
- the fixing of the element E on the branch 4 is carried out via a G2 pin driven into opposite holes, made respectively in branch 4 and in the two branches b, b '.
- element E comprises a second part, called attachment, extending above the plane of branch 4 and comprising a fixing eyelet for receiving a pin (not shown) for fixing a strand of bracelet.
- the clasp 1 ' includes a base 72 formed of two parallel branches 74, 76 and two arms 78 and 80 articulated by one of their ends at ends of branches 74, 76.
- the others ends of arms 78 and 80 respectively include fixing means 14, 32 of a bracelet strand 6, 8 partially shown in broken lines in the figure.
- the clasp 1 'further comprises a member for stiffening 82 connecting the branches 74 and 76 in their middle zone, which delimits with the branches 74, 76 two free spaces 84, 86 of generally rectangular shape in which the arms 78, 80 can be respectively included in the closed position of the clasp, the ends of the arms connected to the strands of the bracelet then being substantially juxtaposed.
- the clasps of the invention have the advantage very easy to manufacture because, for branches like for the arm or arms, these elements can be obtained from cut, bent and assembled. There is therefore no stamping operations with material losses and the cost of tooling than that drives.
- the clasp of the invention also has a simple line giving it great elegance.

Abstract
Description
L'invention concerne un fermoir du type à boucle déployante pour bracelet, notamment pour un bracelet de montre, et plus particulièrement un tel fermoir comportant au moins une branche, au moins un bras articulé par une première de ses extrémités sur une première extrémité de ladite branche, ladite branche ayant une face latérale disposée en regard d'une face latérale dudit bras dans la position fermée du fermoir, et des moyens de blocage pour bloquer le fermoir dans ladite position fermée.The invention relates to a buckle type clasp. deployant for a bracelet, in particular for a bracelet watch, and more particularly such a clasp comprising at least one branch, at least one arm articulated by a first of its ends on a first end of said branch, said branch having a lateral face arranged opposite a lateral face of said arm in the closed position of the clasp, and locking means for lock the clasp in said closed position.
Un fermoir répondant à la définition générique ci-dessus est décrit dans le document EP-A- 0 509 938 . Dans ce document, le fermoir comprend deux bras qui sont articulés sur des brins du bracelet par une de leurs extrémités et sur des extrémités de deux branches parallèles d'un élément central en forme de brancard, par leur autre extrémité. L'élément central présente deux échancrures de forme et de dimensions correspondant à celles des bras de façon que les bras soient entièrement inclus dans les échancrures en position fermée du bracelet. Le blocage du fermoir en position fermée est assuré par un système à cran. Pour assurer ce crantage, l'extrémité du bras qui est attachée au brin présente un bec dont une des parties présente une gorge qui coopère avec un organe cylindrique ou pont reliant les branches après qu'il ait été engagé élastiquement sur ce dernier.A clasp meeting the generic definition above is described in document EP-A- 0 509 938. In this document, the clasp includes two arms which are articulated on strands of the bracelet by one of their ends and on ends of two branches parallels of a central element in the form of a stretcher, by their other end. The central element has two notches of shape and size corresponding to those of the arms so that the arms are fully included in the notches in the closed position of the bracelet. The locking of the clasp in the closed position is provided by a notch system. To ensure this notching, the end of the arm which is attached to the strand has a beak one of the parts of which has a cooperating groove with a cylindrical member or bridge connecting the branches after it has been elastically engaged on the latter.
Ce système de crantage présente l'inconvénient d'être soumis à une usure rapide ce qui a pour résultat que la fermeture n'est plus assurée efficacement après un certain nombres d'ouvertures et de fermetures.This notching system has the disadvantage of being subject to rapid wear which results in the closure is no longer effectively guaranteed after a certain numbers of openings and closings.
Cette usure rapide conduit également à des variations considérables des forces d'ouverture et de fermeture, ce qui est insatisfaisant pour l'utilisateur, ces forces étant par ailleurs dépendantes de la nature des matériaux utilisés pour la réalisation du fermoir.This rapid wear also leads to variations considerable opening and closing forces, which is unsatisfactory for the user, these forces being also dependent on the nature of the materials used to make the clasp.
A cela s'ajoute le jeu inhérent existant entre la gorge et l'organe cylindrique qui donne au système de crantage une impression de qualité médiocreAdded to this is the inherent play between the throat and the cylindrical organ which gives the system of notches an impression of poor quality
Par ailleurs, ce fermoir est relativement difficile à réaliser avec précision car il demande de nombreuses opérations mécaniques notamment d'usinage de reprise après étampage des branches et des bras, et d'ajustage du bec avec le pont avant montage du fermoir, afin d'obtenir une force d'ouverture et une force de fermeture acceptables.Furthermore, this clasp is relatively difficult to achieve precisely because it requires many mechanical operations, in particular rework machining after stamping of branches and arms, and adjustment of the beak with the bridge before mounting the clasp, in order to obtain a acceptable opening force and closing force.
On connaÃt également du document FR-E-41 138 un fermoir du type à bouche déployante pour bracelet comprenant deux branches et un bras articulé par une de ses extrémités sur une extrémité des branches, le bras étant prévu pour s'effacer entre les branches en position de fermeture du fermoir. Le bras comporte des saillies latérales destinées à venir s'engager, dans la position de fermeture, dans des logements correspondants ménagés dans les branches, ces dernières étant élastiquement déformables grâce à des fentes longitudinales ménagées dans celles-ci à cet effet. Ce fermoir présente toutefois les mêmes inconvénients que ceux évoqués en liaison avec le fermoir décrit dans le document EP-A-0 509 938.We also know from document FR-E-41 138 a folding clasp type for bracelet comprising two branches and an arm articulated by one of its ends on one end of the branches, the arm being intended to disappear between the branches in position closing the clasp. The arm has projections lateral intended to come to engage, in the position of closure, in corresponding housing provided in the branches, the latter being elastically deformable thanks to longitudinal slots in these for this purpose. However, this clasp has the same disadvantages as those mentioned in connection with the clasp described in document EP-A-0 509 938.
L'invention a donc pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant un fermoir du type à bouche déployante, notamment pour un bracelet de montre ou analogue, comprenant un système fiable de blocage du fermoir dans sa position fermée et qui, tout en conférant un aspect esthétique amélioré au fermoir dans son ensemble, peut être réalisé de façon simple et économique.The main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a clasp of the folding mouth type, in particular for a watch strap or the like, including a reliable clasp locking system in its closed position and which, while imparting an improved aesthetics to the clasp as a whole, can be carried out in a simple and economical way.
A cet effet l'invention a pour objet un fermoir du type à bouche déployante comprenant au moins une branche et au moins un bras articulé par une première de ses extrémités sur une première extrémité de ladite branche, ladite branche ayant une face latérale disposée en regard d'une face latérale dudit bras dans la position fermée du fermoir, et des moyens de blocage pour bloquer le fermoir dans ladite position fermée, les moyens de blocage comprenant au moins un élément élastiquement déformable qui s'étend, en position fermée du fermoir, dans un logement formé d'une part par une creusure longitudinale ménagée dans ladite face latérale de ladite branche caractérisé en ce que d'autre part une creusure longitudinale est ménagée dans ladite face latérale dudit bras.To this end the invention relates to a clasp of the folding mouth type comprising at least one branch and at least one arm articulated by a first of its ends on a first end of said branch, said branch having a side face disposed opposite of a lateral face of said arm in the closed position of the clasp, and blocking means for blocking the clasp in said closed position, the locking means comprising at least one elastically deformable element which extends, in the closed position of the clasp, in a housing formed on the one hand by a longitudinal recess formed in said lateral face of said branch characterized in that on the other hand a longitudinal recess is formed in said side face of said arm.
Grâce à ces caractéristiques, on obtient un fermoir de structure simple et économique et qui présente une force de fermeture et une force d'ouverture constantes au cours du temps, ces dernières pouvant facilement être maÃtrisées en ajustant les dimensions et/ou la raideur de l'élément élastiquement déformable quelle que soit la nature du ou des matériaux utilisés pour réaliser les autres pièces du fermoir.Thanks to these characteristics, a clasp is obtained simple and economical structure and which has a constant closing force and opening force at over time, these can easily be controlled by adjusting the dimensions and / or the stiffness of the elastically deformable element whatever the nature of the material (s) used to make the other parts of the clasp.

La figure 1 montre, en perspective, un premier mode de réalisation d'un fermoir du type à bouche déployante selon l'invention et désigné par la référence numérique générale 1.Figure 1 shows, in perspective, a first mode for making a clasp of the folding mouth type according to the invention and designated by the reference numeral general 1.
Le fermoir 1 comprend essentiellement une base 2 et
un bras 4. Ces éléments sont articulés l'un sur l'autre
par l'une de leurs extrémités et reliés par leur autre
extrémité à des premier et deuxième brins 6, 8 d'un
bracelet. Les brins 6 et 8 partiellement représentés en
traits interrompus à la figure sont attachés à un objet Ã
porter, notamment une montre (non représentée).The
La base 2 a la forme d'une lame mince allongée,
légèrement incurvée dans le sens de la longueur afin de
s'adapter à la courbure du poignet. La base 2 comprend
deux branches parallèles 10 et 12 reliées ensemble Ã
chacune de leurs extrémités par des moyens de liaison 14
et 16 et délimitant entre elles un espace libre 18
longitudinal sensiblement rectangulaire. Dans l'exemple
représenté, les moyens de liaison 14 sont formés par un
tube dont les parties extrêmes sont fixées par exemple par
soudage sur les surfaces supérieures 20 et 22 d'une
extrémité des branches 10 et 12. Le tube 14 est destiné Ã
recevoir une goupille (non représentée) autour de laquelle
est enroulé le brin de bracelet 8 et forme ainsi des
moyens de fixation du brin de bracelet 8.The base 2 has the shape of an elongated thin blade,
slightly curved lengthwise in order to
adapt to the curvature of the wrist. Base 2 includes
two
Les moyens de liaison 16 situés à l'extrémité des
branches 10 et 12 sur laquelle est articulé le bras 4
comprennent une charnière. La figure 2 indique une façon
de réaliser la charnière 16. Un tube 24 muni d'encoches 26
est chassé dans une ouverture prévue à cet effet dans les
autres extrémités des branches 10 et 12 et le bras 4
pivote autour du tube 24. Des goupilles 28 pourvues
chacune d'une rainure 30 sont introduites dans le tube 24
et y sont maintenues en place par le truchement des
encoches 26 qui pénètrent dans les rainures 30. On réalise
ainsi un assemblage facilement montable et démontable.The
Le bras 4, de son côté, est formé d'une lame allongée
qui a la même épaisseur et présente la même courbure
longitudinale que celles de la base 2. De forme générale
rectangulaire, ses dimensions lui permettent de prendre
place dans l'espace libre 18 de la base 2. A une
extrémité, le bras 4 est traversé par un trou par lequel
passe le tube encoché 24 permettant au bras 4 de pivoter
autour du tube 24. L'autre extrémité du bras 4 est munie
de moyens de fixation 32 du deuxième brin de bracelet 16,
formés également par un tube susceptible de recevoir une
goupille (non représentée) autour de laquelle est enroulé
le brin de bracelet 6. Le tube 32 est fixé par exemple par
soudage sur une partie extrême de la surface supérieure 34
du bras 4.
Dans l'exemple de réalisation représenté, le tube 14
et le tube 32 sont notamment adaptés à la fixation de
brins de bracelet du type à maillons métalliques, mais il
va de soi que ces moyens de fixation peuvent être
facilement modifiés par l'homme de métier pour recevoir
des brins de bracelet réalisés par exemple en cuir ou
analogue.In the embodiment shown, the
Dans l'exemple décrit, le bras 4 présente
une longueur légèrement supérieure à la longueur des
branches 10, 12 et comprend dans sa surface supérieure 34
une rainure transversale 36 ménagée pour, dans la position
fermée du fermoir, venir en correspondance avec le tube 14
et recevoir ce dernier. Ainsi, quand le fermoir est en
position fermée, ce qui apparait aux figures 2 et 3 le
bras 4 est inclus dans l'épaisseur des branches 10 et 12 Ã
l'exception du tube 32 qui émerge de l'épaisseur du
fermoir au même niveau que le tube 14. On notera que dans
le mode de réalisation décrit, le bras 4 doit pivoter dans
le sens de la flèche F de la figure 1 pour amener le
fermoir dans sa position ouverte. Il est bien entendu
possible de prévoir, selon une variante, un bras 4 plus
court que les branches 10 et 12 de sorte qu'il ne soit pas
arrêté par le tube 14 et qu'il puisse pivoter dans un sens
opposé pour amener le fermoir dans sa position ouverte.
Dans ce cas, la fixation de brins de bracelet sur la base
et le bras sera modifiée en conséquence.In the example described, the
Le fermoir 1 comprend en outre des moyens de blocage
pour bloquer le fermoir, c'est-Ã -dire le bras 4 par
rapport aux branches 10 et 12, dans sa position fermée. A
cet effet, les branches 10 et 12 comprennent chacune une
face latérale 36, dans laquelle est ménagée une creusure
longitudinale 40, 42. Le bras 4 comprend deux faces
latérales opposées 44, 46, chacune étant également munie
d'une creusure longitudinale 48, 50. Chaque creusure 40 et
42 des branches 10 et 12 est ménagée pour, en position
fermée du fermoir, être en regard d'une des creusures 48,
50 du bras et former ainsi deux logements longitudinaux
parallèles 52, 54 (cf fig. 3) dans chacun desquels s'étend
un élément élastiquement déformable 56, 58.The
Chaque élément élastiquement déformable 56, 58
s'étend partiellement dans chacune des creusures formant
son logement 52, 54 si bien que ces éléments 56, 58
réalisent un blocage du bras 4 sur les branches 10, 12.Each elastically
Dans l'exemple représenté, les éléments élastiquement
déformables 56 et 58 comprennent chacun un ressort
hélicoïdal et les logements 52 et 54 présentent une
section sensiblement circulaire.In the example shown, the elements elastically
deformable 56 and 58 each include a spring
helical and the
Le fermoir comprend en outre des moyens de maintien
de chaque élément élastiquement déformable 56, 58 dans une
des creusures formant son logement, en l'occurrence dans
les creusures 48 et 50 ménagées dans le bras 4, pour qu'il
soit retenu dans ladite creusure quand le fermoir est en
position ouverte.The clasp further comprises holding means
of each elastically
Dans l'exemple décrit et comme cela apparait
clairement à la figure 3, les creusures 48, 50 débouchent
respectivement dans les faces latérales 36 et 38 du bras 4
par des ouvertures délimitées par deux bords 60, 62 et 64,
66 séparés d'une distance inférieure au diamètre des
ressorts 56 et 58. L'axe longitudinal L de chacun des
ressorts 56, 58 est donc contenu dans la creusure 48, 50
qui le reçoit. Ainsi, les creusures 48 et 50 s'étendent,
en section, sur un arc de cercle supérieur à 180° et de
préférence sur un arc d'environ 240°.In the example described and as it appears
clearly in Figure 3, the
Quant aux creusures 40, 42 ménagées dans les faces
latérales des branches 10, 12, elles s'étendent en section
sur un arc de cercle inférieur à 90° et de préférence égal
à environ 60°.As for the
Il est bien entendu que les creusures 40, 42, 48 et
50 peuvent présenter des sections différentes et par
exemple, la section des creusures 48, 50 qui retiennent
l'élément élastiquement déformable 56, 58 peut être en
queue d'aronde ou en T, et la section des creusures 40,
42 complémentaires peuvent être en U ou de tout autre
forme présentant une concavité permettant de former un
logement susceptible de recevoir les éléments
élastiquement déformables 56, 58.It is understood that the
Le diamètre des ressorts 56, 58 est légèrement
inférieur au diamètre des logements 52, 54 si bien qu'il
existe un certain jeu entre les ressorts 56, 58 et les
logements 52, 54 et a fortiori, entre les ressorts 56, 58
et les creusures 48, 50 dans lesquelles ils sont
maintenus. Les ressorts 56, 58 peuvent ainsi se déformer
sans difficulté lors de l'ouverture et de la fermeture du
fermoir 1 comme cela sera décrit ci-après.The diameter of the
On remarquera que les faces latérales 36 et 38 des
branches 10 et 12 comprennent respectivement des rampes
d'encliquetage 68, 70 ménagées dans les parties
inférieures de ces faces. Ces rampes 68 et 70 s'étendent
respectivement des bords inférieurs des faces 36, 38
jusqu'aux bords inférieurs des creusures 40, 42. Ces
rampes 68, 70 permettent aux éléments élastiquement
déformables de se déformer progressivement lors de la
fermeture du fermoir comme cela apparaÃtra plus clairement
dans la suite de la description.It will be noted that the lateral faces 36 and 38 of the
Le fermoir 1 comprend en outre des moyens d'arrêt 72,
74 des ressorts 56, 58 en direction longitudinale dans les
creusures 48, 50. Ces moyens d'arrêt 72, 74 sont formés
par au moins deux spires jointives d'extrémité des
ressorts 56, 58 et dont le diamètre, lorsque ces ressorts
ne sont pas montés dans les creusures 48, 50, est
sensiblement supérieur à celui des logements 52, 54.
Ainsi, les ressorts 56, 58 peuvent être introduits
aisément dans la creusure 48, 50 correspondante par leur
extrémité ayant un diamètre sensiblement inférieur à celui
du logement, les dernières spires 72, 74 formant les
moyens d'arrêt dans les creusures 48, 50 étant ensuite
forcées dans ces creusures 48, 50 pour assurer un arrêt
dans le sens longitudinal des ressorts 56, 58 dans ces
dernières. Selon une variante, les spires 72, 74 formant
les moyens d'arrêt peuvent respectivement coopérer avec
des gorges annulaires (non représentées) ménagées dans les
creusures 48, 50.The
Le principe de fonctionnement du fermoir qui vient
d'être décrit est le suivant: au cours de la fermeture, le
bras , lorsqu'il est poussé dans le sens de la flèche F1,
provoque le frottement des rampes d'encliquetage 68, 70
des branches 10, 12 sur les parties des ressorts 56, 58
qui font saillie hors des creusures 48, 50, ce qui a pour
effet de déformer élastiquement les spires des ressorts
56, 58 de sorte qu'elles s'effacent momentanément, jusqu'Ã
ce que ces parties en saillie des ressorts 56, 58
pénètrent progressivement dans les creusures 40, 42
complémentaires ménagées dans les branches 10, 12 et
assurent ainsi un blocage du bras 4 entre les deux
branches 10, 12.The operating principle of the clasp that comes
to be described is as follows: during closure, the
arm, when pushed in the direction of arrow F1,
causes friction of the latching ramps 68, 70
Lors de l'ouverture, le bras est poussé dans le sens
de la flèche F et sollicite simultanément la totalité des
spires des ressorts 56, 58 pour les déformer et libérer le
bras 4. Il résulte de la structure des moyens de blocage
que la force à déployer pour l'ouverture du fermoir est
plus grande que celle qui est nécessaire à sa fermeture,
ce qui confère au fermoir un plus grand confort
d'utilisation au porteur et une grande sécurité en
position fermée.When opening, the arm is pushed in the direction
arrow F and simultaneously requests all of the
turns of the
A ce propos, pour ouvrir le fermoir, il sera
avantageux de munir l'extrémité du brin 8 d'un onglet (non
représenté). In this regard, to open the clasp, it will
advantageous to provide the end of the
En outre, on remarquera que les forces de fermeture et d'ouverture dépendent essentiellement des caractéristiques des ressorts, de sorte qu'elles peuvent être aisément ajustées. Pour ce faire, il suffit d'agir sur les paramètres caractéristiques de chaque ressort, à savoir le diamètre du fil et le nombre de spires du ressort.In addition, it will be noted that the closing forces and openness essentially depend on characteristics of the springs, so that they can be easily adjusted. To do this, just act on the characteristic parameters of each spring, to know the diameter of the wire and the number of turns of the spring.
En se référant aux figures 4 et 5, on voit une variante de réalisation du fermoir qui est représenté aux figures 1 à 3 dans laquelle les mêmes éléments sont désignés par les mêmes références numériques.Referring to Figures 4 and 5, we see a alternative embodiment of the clasp which is shown in Figures 1 to 3 in which the same elements are designated by the same reference numerals.
A la différence du premier mode de réalisation, le
tube soudé 14 a été remplacé par des moyens de liaison 14
du type de ceux référencés en 16 à la figure 2 et dans
lesquelles un tube 15 fait office d'entretoise pour
maintenir une distance convenable entre les branches 10 et
12 du fermoir.Unlike the first embodiment, the
welded
Par ailleurs, les branches 10 et 12 sont chacune
prolongées au-delà des moyens de liaison 14 par des
parties de branche 10' et 12'. Chaque partie de branche
10' et 12' comprend un trou 11' et 13', ces derniers étant
disposés en regard l'un de l'autre et étant destinés Ã
recevoir une goupille (non représentée) pour la fixation
d'un brin de bracelet.Furthermore,
Dans cette variante de réalisation, les ressorts 56
et 58 sont respectivement arrêtés longitudinalement dans
les creusures 48 et 50 par une première de leurs
extrémités, par les extrémités d'une goupille G1 chassée
dans un trou ménagé dans la branche 4, les deux extrémités
de la goupille s'étendant respectivement dans les
creusures 48 et 50.In this alternative embodiment, the
Par ailleurs, les ressorts 56 et 58 sont
respectivement maintenus contre les extrémités de la
goupille G1 par l'intermédiaire d'un élément E fixé sur la
branche 4. Plus précisément, l'élément E comprend une
partie en forme de U dont les branches b, b' s'étendent
respectivement dans les creusures 48 et 50 et s'appuient
contre la deuxième extrémité des ressorts 56 et 58. La
fixation de l'élément E sur la branche 4 est réalisée via
une goupille G2 chassée dans des trous en regard, ménagés
respectivement dans la branche 4 et dans les deux branches
b, b'. Comme cela ressort particulièrement de la figure 4,
l'élément E comprend une deuxième partie, dite de
fixation, s'étendant au-dessus du plan de la branche 4 et
comprenant un oeillet de fixation destiné à recevoir une
goupille (non représentée) pour la fixation d'un brin de
bracelet.Furthermore, the
On notera également que selon cette variante de réalisation l'ouverture du fermoir s'effectue selon un déplacement vers le haut et dans le sens de la flèche F2 au dessin.It will also be noted that according to this variant of the opening of the clasp is carried out according to a upward movement and in the direction of arrow F2 to the drawing.
En se référant maintenant à la figure 6, on voit un deuxième mode de réalisation dans lequel les mêmes éléments que ceux représentés aux figures 1 à 5 sont désignés par les mêmes références numériques.Referring now to Figure 6, we see a second embodiment in which the same elements that those shown in Figures 1 to 5 are designated by the same reference numerals.
Dans ce deuxième mode de réalisation, le fermoir 1'
comprend une base 72 formée de deux branches parallèles
74, 76 et deux bras 78 et 80 articulés par l'une de leurs
extrémités aux extrémités des branches 74, 76. Les autres
extrémités des bras 78 et 80 comprennent respectivement
des moyens de fixation 14, 32 d'un brin de bracelet 6, 8
représenté partiellement en traits interrompu à la figure.In this second embodiment, the clasp 1 '
includes a base 72 formed of two
Le fermoir 1' comprend en outre un organe de
rigidification 82 reliant les branches 74 et 76 dans leur
zone médiane, ce qui délimite avec les branches 74, 76
deux espaces libres 84, 86 de forme générale rectangulaire
dans lesquels les bras 78, 80 peuvent être respectivement
inclus en position fermée du fermoir, les extrémités des
bras reliées aux brins du bracelet étant alors
sensiblement juxtaposées.The clasp 1 'further comprises a member for
stiffening 82 connecting the
Ce fermoir 1' peut donc être considéré comme étant
formé de deux fermoirs 1 tels que représentés sur les
figures 1 à 3 réunis l'un à l'autre par une de leurs
extrémités et utilisant les mêmes moyens de blocage que
ceux qui ont été décrits en liaison avec ces figures.This clasp 1 'can therefore be considered to be
formed of two
Les fermoirs de l'invention présentent l'avantage d'une fabrication très aisée car, pour les branches comme pour le bras ou les bras, ces éléments peuvent être obtenus à partir de profilés découpés, cintrés et assemblés. Il n'y a donc pas d'opérations d'étampage avec les pertes de matière et le coût de l'outillage que cela entraÃne. Le fermoir de l'invention présente en outre une ligne simple lui conférant une grande élégance.The clasps of the invention have the advantage very easy to manufacture because, for branches like for the arm or arms, these elements can be obtained from cut, bent and assembled. There is therefore no stamping operations with material losses and the cost of tooling than that drives. The clasp of the invention also has a simple line giving it great elegance.
Il est bien entendu que l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et que de nombreuses variantes évidentes pour l'homme du métier peuvent être réalisées sans sortir du cadre de la présente invention définie par les revendications annexées. On peut par exemple prévoir des moyens de blocage ne présentant qu'un seul logement coopérant avec un unique élément élastiquement déformable. On peut également prévoir que l'élément élastiquement déformable soit non pas réalisé sous la forme une ressort hélicoidal mais sous la forme d'un cylindre en un matériau élastomère ou encore d'un tube en un matériau élastiquement déformable, que les éléments élastiquement déformables ne soient pas maintenus dans le ou les bras mais dans les branches ou encore que le fermoir ne comprenne qu'une branche et un bras articulés l'un sur l'autre par leurs extrémités.It is understood that the invention is not limited to the embodiments which have just been described and that many variations evident to the man of the trade can be carried out without departing from the present invention defined by claims attached. One can for example provide means of blocking having only one housing cooperating with a single elastically deformable element. We can also provide that the elastically deformable element either not produced in the form of a helical spring but in the form of a cylinder made of an elastomeric material or a tube made of an elastic material deformable, that the elastically deformable elements do not are not held in the arm (s) but in the branches or that the clasp includes only one branch and one arm hinged on each other by their extremities.
