Description

La présente invention concerne un fermoir du type à boucle déployante qu'il soit équipé de deux dépliants ou d'un seul dépliant, ce ou ces dépliants étant articulés sur un élément de base.The present invention relates to a clasp type folding clasp it is equipped with two leaflets or a single leaflet, this or these leaflets being articulated on a base member.

Un premier mode d'exécution de l'invention est relatif à un fermoir du type à boucle déployante comprenant un élément de base sensiblement rectangulaire dont les premier et second grands côtés sont formés respectivement de premier et second longerons, et des premier et second dépliants pivotant et articulés sur des premier et second côtés dudit élément de base, lesdits dépliants étant arrangés pour être rabattus sur ledit élément de base et y être maintenu en réponse à un dispositif élastique associé à un mécanisme de verrouillage et de déverrouillage affectant ledit élément de base et lesdits dépliants pour permettre respectivement l'accrochage desdits premier et second dépliants sur ledit élément de base puis leur décrochage.A first embodiment of the invention relates to a folding clasp type clasp comprising a substantially rectangular base member whose first and second long sides are formed respectively of first and second longitudinal members, and first and second pivoting leaflets and articulated on first and second sides of said base member, said leaflets being arranged to be folded over said base member and held therein in response to an elastic device associated with a locking and unlocking mechanism affecting said base member and said leaflets to respectively allow the attachment of said first and second leaflets on said base member and their stall.

Des fermoirs de bracelet répondant à la description donnée au paragraphe ci-dessus sont connus de l'état de la technique.Bracelet clasps as described in the above paragraph are known from the state of the art.

Le document EP 1 925.227 B1 montre un fermoir formé d'une base et de deux dépliants arrangés pour être rabattus sur la base et y être maintenu en réponse à un dispositif élastique composé d'un ou de deux ressorts à boudin. Pour éviter ce ou ces ressorts et simplifier la construction du fermoir, le document CH 703294 propose un fermoir composé d'un élément de base sur lequel deux dépliants sont susceptibles d'être rabattus et maintenus accrochés en jouant sur l'élasticité contenue dans les longerons formant l'élément de base (voir en particulier la figure 3 dudit document). En appuyant sur des poussoirs faisant corps avec les longerons, on libère les dépliants de tout accrochage et on permet l'ouverture du fermoir.The document EP 1 925.227 B1 shows a clasp formed of a base and two leaflets arranged to be folded over the base and held therein in response to an elastic device consisting of one or two coil springs. To avoid this or these springs and simplify the construction of the clasp, the document CH 703294 proposes a clasp composed of a base element on which two leaflets are likely to be folded and held hooked by acting on the elasticity contained in the longitudinal members forming the base element (see in particular the figure 3 of said document). By pushing buttons that are longitudinal members, the leaflets are released from any attachment and the opening of the clasp is allowed.

La solution proposée par le document CH 703294 pose cependant la question qui consiste à assurer à l'élément de base une bonne rigidité constructive tout en conférant aux longerons le constituant, l'élasticité nécessaire au bon maintien du dépliant sur l'élément de base et en permettant la libération desdits dépliants quand une force est exercée sur lesdits longerons.The solution proposed by the document CH 703294 poses however the question which is to ensure the basic element a good constructive rigidity while giving the longitudinal members the constituent, the elasticity necessary for the proper maintenance of the leaflet on the base element and allowing the release of said leaflets when a force is exerted on said longitudinal members.

Pour apporter une réponse à la question posée ci-dessus, la présente invention, outre qu'elle obéit à la définition générique exprimée au deuxième paragraphe de cette description relatif au premier mode d'exécution de l'invention, est remarquable en ce que l'élément de base comporte des premier et second longerons faits chacun d'au moins deux lames à ressort qui constituent ledit dispositif élastique, une pression exercée simultanément sur chacun des longerons conduisant au déverrouillage desdits dépliants dudit élément de base.To provide an answer to the question posed above, the present invention, in addition to fulfilling the generic definition expressed in the second paragraph of this description relating to the first embodiment of the invention, is remarkable in that base element comprises first and second spars each made of at least two spring blades which constitute said elastic device, a pressure exerted simultaneously on each of the longitudinal members leading to the unlocking of said leaflets of said base member.

Un second mode d'exécution de l'invention est relatif à un fermoir du type à boucle déployante comprenant un élément de base sensiblement rectangulaire dont les premier et second grands côtés sont formés respectivement de premier et second bras rigides et un dépliant pivotant et articulé sur l'un des petits côtés dudit élément de base, ledit dépliant comprenant des premier et second longerons, ce dépliant étant arrangé pour être rabattu sur ledit élément de base et y être maintenu en réponse à un dispositif élastique associé à un mécanisme de verrouillage et de déverrouillage affectant ledit élément de base et ledit dépliant pour permettre respectivement l'accrochage dudit dépliant sur ledit élément de base puis son décrochage.A second embodiment of the invention relates to a folding clasp type clasp comprising a substantially rectangular base member whose first and second long sides are formed respectively of first and second rigid arms and a pivoting leaflet and hinged on one of the short sides of said base member, said leaflet comprising first and second longitudinal members, said leaflet being arranged to be folded over said base member and held therein in response to an elastic device associated with a locking mechanism and unlocking affecting said base member and said leaflet to respectively allow the attachment of said leaflet on said base member and its stall.

Un fermoir répondant sensiblement à la description donnée au paragraphe ci-dessus est exposé dans le document EP 2502515 qui montre un fermoir formé d'une base comprenant deux bras rigides et un dépliant arrangé pour être rabattu sur cette base et y être maintenu accroché en jouant sur l'élasticité contenue dans les longerons formant ledit dépliant (voir en particulier la figure 1 dudit dépliant). En appuyant sur des poussoirs faisant corps avec les longerons, on libère le dépliant de tout accrochage et on permet l'ouverture du fermoir.A clasp corresponding substantially to the description given in the paragraph above is set out in the document EP 2502515 which shows a clasp formed of a base comprising two rigid arms and a leaflet arranged to be folded down on this base and to be held there hanging by acting on the elasticity contained in the longitudinal members forming said leaflet (see in particular the figure 1 said leaflet). By pressing pushers integral with the longitudinal members, the leaflet is released from any attachment and the opening of the clasp is allowed.

La solution proposée par ce document pose cependant la question qui consiste à assurer au dépliant une bonne rigidité constructive tout en conférant aux longerons le constituant l'élasticité nécessaire au bon maintien dudit dépliant sur ledit élément de base et en permettant la limitation dudit dépliant quand une force est exercée sur lesdits longerons.The solution proposed by this document, however, raises the question of ensuring the leaflet a good constructive rigidity while giving the longitudinal members the constituent elasticity necessary for the proper maintenance of said leaflet on said base element and allowing the limitation of said leaflet when a force is exerted on said longitudinal members.

Pour apporter une réponse à la question posée ci-dessus, la présente invention, outre qu'elle obéit à la définition générique exprimée au paragraphe ci-dessus relatif au second mode d'exécution de l'invention, est remarquable en ce que le dépliant comporte des premier et second longerons faits chacun d'au moins deux lames à ressort qui constituent ledit dispositif élastique, une pression exercée simultanément sur chacun des longerons conduisant au déverrouillage dudit dépliant sur le dit élément de base.To provide an answer to the question posed above, the present invention, in addition to fulfilling the generic definition expressed in the above paragraph relating to the second embodiment of the invention, is remarkable in that the leaflet comprises first and second spars each made of at least two spring blades which constitute said elastic device, a pressure exerted simultaneously on each of the longitudinal members leading to the unlocking of said leaflet on said base element.

The features and advantages of the present invention will emerge from the description which follows, made with reference to the accompanying drawings and giving by way of illustrative but not limiting example, two advantageous forms of execution of a clasp, drawings in which:
  • the figure 1 is a perspective view of the clasp according to the invention and executed according to the first embodiment where on the base element are folded two leaflets,

  • the figure 8 is a plan view of the clasp executed according to the figure 6 , and
  • the figure 9 is a section executed along line IX - IX of the figure 8 .

Les figures 1 - 5 sont relatives au premier mode d'exécution du fermoir réalisé selon l'invention, première exécution qui va être expliquée maintenant en détail.The Figures 1 - 5 are relative to the first embodiment of the clasp made according to the invention, the first embodiment which will now be explained in detail.

Les figures 1 et 2 sont des vues en perspective du fermoir de bracelet du type à boucle déployante qui comprend un élément de base 50 sensiblement rectangulaire. Cet élément comporte des premier et second grands côtés formés respectivement de premier 1 et second 2 longerons. Le fermoir comprend encore des premier 3 et second 4 dépliants qui sont montés pivotant et articulés respectivement sur les premier et second petits côtés de l'élément de base 50 autour de premier 60 et second 61 arbres, ces arbres étant maintenus en place par des vis 62. Les dépliants 3 et 4 sont arrangés pour être rabattus sur l'élément de base 50 et notamment à l'intérieur dudit élément comme l'explicitent bien les figures 1 à 5. Lesdits dépliants 3 et 4 sont maintenus en position rabattue sur l'élément de base 50 en réponse à un dispositif élastique associé à un mécanisme de verrouillage et de déverrouillage affectant ledit élément de base 50 et lesdits dépliant 3 et 4 pour permettre respectivement l'accrochage desdits premier 3 et second 4 dépliants sur ledit élément de base 50 puis leur décrochage.The Figures 1 and 2 are perspective views of the clasp type clasp clasp which includes a substantially rectangular base member 50. This element comprises first and second long sides formed respectively of first 1 and second 2 longitudinal members. The clasp further comprises first 3 and second 4 leaflets which are pivotally mounted and hinged respectively on the first and second short sides of the base member 50 around first 60 and second 61 shafts, these shafts being held in place by screws 62. The leaflets 3 and 4 are arranged to be folded down on the base element 50 and in particular inside said element as explained by the Figures 1 to 5 . Said leaflets 3 and 4 are held in the folded position on the base element 50 in response to an elastic device associated with a locking and unlocking mechanism affecting said base member 50 and said leaflet 3 and 4 to respectively allow the hooking of said first 3 and second 4 leaflets on said base member 50 and then their stalling .

Par rapport à ce qui vient d'être dit ci-dessus, en principe connu de documents antérieurs, le fermoir de la présente invention se distingue par l'originalité du dispositif élastique mis en oeuvre et qui consiste à proposer des premier 1 et second 2 longerons faits chacun d'au moins deux lames à ressort. Sur les dessins des figures 1 à 5 le premier longeron 1 porte les lames à ressort 5 et 7 et le second longeron 2 porte les lames à ressort 6 et 8.Compared to what has just been said above, in principle known from prior documents, the clasp of the present invention is distinguished by the originality of the elastic device used and which consists in providing first 1 and second 2 rails each made of at least two spring blades. On the drawings of Figures 1 to 5 the first spar 1 carries the spring blades 5 and 7 and the second spar 2 carries the spring blades 6 and 8.

La présente invention propose ainsi au moins deux lames à ressort pour équiper chacun des longerons constituant les grands côtés de l'élément de base et non une seule lame par souci d'assurer une bonne rigidité audit élément de base et d'éviter ainsi son gauchissement. D'autre part l'utilisation de lames à ressort minces par principe, apporte plusieurs avantages . Leur fabrication est économique car elles peuvent être découpées aisément, les moyens utilisés pour réaliser cette découpe étant choisis en fonction des matériaux choisis pour la réalisation des lames, comme par exemple, le jet d'eau, le laser ou l'étampage. Un autre avantage réside dans le large choix des matériaux à disposition, par exemple des composites, des métaux amorphes ou des aciers pour ressort. Enfin on peut mentionner que les propriétés des lames peuvent être modifiées de plusieurs façons parmi lesquelles on peut citer le découpage des lames dans des feuilles plus ou moins épaisses, l'empilage des lames et le changement de leur matière de base.The present invention thus proposes at least two spring blades to equip each of the longitudinal members constituting the long sides of the base member and not a single blade for the sake of ensuring good rigidity to said base member and thus to avoid buckling. . On the other hand the use of thin spring blades by principle, brings several advantages. Their manufacture is economical because they can be cut easily, the means used to achieve this cutting being chosen according to the materials chosen for the production of the blades, such as, for example, water jet, laser or stamping. Another advantage lies in the wide choice of materials available, for example composites, amorphous metals or spring steels. Finally, it can be mentioned that the properties of the blades can be modified in several ways among which can be mentioned the cutting of the blades in more or less thick sheets, the stacking of the blades and the change of their base material.

Ici l'empilage d'au moins deux lames à ressort permet de doubler la raideur du ressort tout en conservant la flèche que procure une seule lame. Si trois lames étaient utilisées, la raideur de l'ensemble triplerait selon la formule K = nk

Figure imgb0001

où K est la raideur de l'ensemble, n le nombre de lames et k la raideur d'une lame. Autrement dit, avec au moins deux lames à ressort équipant chacune des longerons, on double la force nécessaire pour décrocher les dépliants de l'élément de base tout en conservant le même chemin à parcourir pour ce décrochage.Here the stack of at least two spring blades doubles the stiffness of the spring while maintaining the arrow that provides a single blade. If three blades were used, the stiffness of the whole would triple according to the formula K = nk
Figure imgb0001
where K is the stiffness of the set, n the number of blades and k the stiffness of a blade. In other words, with at least two spring blades equipping each of the longitudinal members, it doubles the force required to pick up the leaflets of the base element while maintaining the same path to go for this stall.

On va décrire maintenant le mécanisme de verrouillage et de déverrouillage mis en oeuvre respectivement pour accrocher et décrocher les premier 3 et second 4 dépliants sur l'élément de base 50. Les figures 2 et 4 montrent que ce mécanisme est composé de premier 9 et second 10 crochets portés par l'extrémité libre 11 que présente le premier dépliant 3 et de troisième 12 et quatrième 13 crochets portés par l'extrémité libre 14 que présente le second dépliant 4. Lesdits premier 9 et troisième 12 crochets sont arrangés pour être verrouillés respectivement par des premier 15 et deuxième 16 verrous portés par ledit premier longeron 1 et lesdits deuxième 10 et quatrième 13 crochets sont arrangés pour être verrouillés respectivement par des troisième 17 et quatrième 18 verrous portés par ledit second longeron 2.We will now describe the locking and unlocking mechanism implemented respectively for hooking and unhooking the first 3 and second 4 leaflets on the base member 50. figures 2 and 4 show that this mechanism is composed of first 9 and second 10 hooks carried by the free end 11 that has the first leaflet 3 and third 12 and fourth 13 hooks borne by the free end 14 that has the second leaflet 4. The said first 9 and third 12 hooks are arranged to be locked respectively by first and second 16 locks carried by said first spar 1 and said second 10 and fourth 13 hooks are arranged to be locked respectively by third 17 and fourth 18 latches carried by said second spar 2.

Les figures 1 à 4 montrent plus particulièrement que les premier 15 et second 16 verrous sont moulés dans un premier élément 65 porté par ledit premier longeron 1 et que les troisième 17 et quatrième 18 verrous sont moulés dans un second élément 66 porté par ledit second longeron 2.The Figures 1 to 4 show more particularly that the first 15 and second 16 locks are molded in a first element 65 carried by said first spar 1 and the third 17 and fourth 18 latches are molded in a second element 66 carried by said second spar 2.

On comprendra qu'une pression latérale exercée sur chacun des longerons 1 et 2 rapprochera les verrous 15 et 17 (voir figure 4) ainsi que les verrous 16 et 18 (voir figure 2) pour dégager respectivement les crochets 9 et 10 solidaires du premier dépliant 3 et les crochets 12 et 13 solidaires du second dépliant 4. Le fermoir est alors en voie d'ouverture. Pour favoriser l'action manuelle exercée sur chacun des longerons, des premier 19 et second 20 poussoirs sont fixés respectivement sur lesdits premier 1 et second 2 longerons. Les figures 1, 2, 3 et 5 montrent de surcroît qu'on a disposé de premières 67 et secondes 68 vis pour assurer la fixation respective de l'ensemble formé par le premier poussoir 19, le premier longeron 1 et le premier élément 65 de l'ensemble formé par le second poussoir 20, le second longeron 2 et le second élément 66.It will be understood that a lateral pressure exerted on each of the longitudinal members 1 and 2 will bring the bolts 15 and 17 closer together (see FIG. figure 4 ) as well as locks 16 and 18 (see figure 2 ) to clear respectively the hooks 9 and 10 secured to the first leaflet 3 and the hooks 12 and 13 integral with the second leaflet 4. The clasp is then in the process of opening. To promote the manual action exerted on each of the longitudinal members, first 19 and second 20 pushers are respectively fixed on said first 1 and second 2 longitudinal members. The Figures 1, 2 , 3 and 5 show moreover that we have first 67 and second 68 screws to ensure the respective attachment of the assembly formed by the first pusher 19, the first spar 1 and the first member 65 of the assembly formed by the second pusher 20 , the second spar 2 and the second element 66.

Les lames à ressort 5, 7 composant le premier longeron 1 et les lames à ressort 6, 8 composant le second longeron 2 peuvent être montées jointives et les dessins ne font pas état de cette construction. Les figures montrent que ces lames sont séparées par des entretoises solides 21. On évite de cette façon les problèmes que peuvent présenter le frottement et la corrosion entre les lames. A noter que ces entretoises diminuent également le gauchissement possible de l'élément de base soit sa résistance à la torsion. On notera encore que les espaces laissés libres entre les entretoises solides 21 pourraient être comblés avec un matériau de remplissage mou, par exemple du caoutchouc.The spring blades 5, 7 composing the first spar 1 and the spring blades 6, 8 composing the second spar 2 can be mounted contiguous and the drawings do not mention this construction. The figures show that these blades are separated by solid spacers 21. This avoids the problems that may present friction and corrosion between the blades. Note that these spacers also reduce the possible warping of the base element is its torsion resistance. It will also be noted that the spaces left free between the solid spacers 21 could be filled with a soft filling material, for example rubber.

Bien que non représenté sur les figures, il va de soi qu'à l'extrémité libre 11 du premier dépliant 3 est fixé un premier brin du bracelet et qu'à l'extrémité libre 14 du second dépliant 4 est fixé un second brin du bracelet.Although not shown in the figures, it is obvious that at the free end 11 of the first leaflet 3 is fixed a first strand of the bracelet and that at the free end 14 of the second leaflet 4 is fixed a second strand of bracelet.

Les figures 6 à 9 sont relatives au second mode d'exécution du fermoir réalisé selon l'invention, seconde exécution qui va être expliquée maintenant en détail.The Figures 6 to 9 relate to the second embodiment of the clasp made according to the invention, the second embodiment which will now be explained in detail.

Les figures 6 et 7 sont des vues en perspectives du fermoir de bracelet du type à boucle déployante qui comprend un élément de base 30 sensiblement rectangulaire. Cet élément comprend des premier et second grands côtés formés respectivement de premier 31 et second 32 bras rigides. Le fermoir comprend encore un dépliant 33 qui est monté pivotant et articulé sur l'un des petits côtés dudit élément de base 30 autour d'un arbre 70 formant ledit petit côté, cet arbre étant maintenu en place par des vis 71. Le dépliant 33 comprend des premier 34 et second 35 longerons et est arrangé pour être rabattu sur l'élément de base 30 et notamment à l'intérieur dudit élément comme l'explicitent bien les figures 6,7 et 8. Le dépliant 33 est maintenu en position rabattue sur l'élément de base 30 en réponse à un dispositif élastique associé à un mécanisme de verrouillage et de déverrouillage affectant ledit élément de base 30 et ledit dépliant 33 pour permettre respectivement l'accrochage dudit dépliant 33 sur ledit élément de base 30 puis son décrochage.The Figures 6 and 7 are perspective views of the clasp type clasp clasp which includes a substantially rectangular base member. This element comprises first and second long sides formed respectively of first 31 and second 32 rigid arms. The clasp still includes a flyer 33 which is pivotally mounted and articulated on one of the short sides of said base member 30 around a shaft 70 forming said small side, this shaft being held in place by screws 71. The leaflet 33 includes first and second spars 34 and is arranged to be folded over the basic element 30 and in particular inside said element as the explicit well the figures 6.7 and 8 . The leaflet 33 is held in the folded position on the base member 30 in response to an elastic device associated with a locking and unlocking mechanism affecting said base member 30 and said leaflet 33 to respectively allow the attachment of said leaflet 33 on said base member 30 and its stall.

Par rapport à ce qui vient d'être dit ci-dessus, le fermoir de la présente invention se distingue par l'originalité du dispositif élastique mis en oeuvre et qui consiste à proposer des premier 34 et second 35 longerons faits chacun d'au moins deux lames à ressort. Sur les dessins des figures 6 à 9 le premier longeron 34 porte les lames à ressort 36 et 37 et le second longeron 35 porte les lames à ressort 38 et 39.Compared to what has just been said above, the clasp of the present invention is distinguished by the originality of the elastic device used and which consists in providing first 34 and second longitudinal members each made of at least two spring blades. On the drawings of Figures 6 to 9 the first spar 34 carries the spring blades 36 and 37 and the second spar 35 carries the spring blades 38 and 39.

La présente invention propose donc au moins deux lames à ressort pour équiper chacun des longerons équipant le dépliant et non une seule lame par souci d'assurer une bonne rigidité audit dépliant et d'éviter ainsi le gauchissement des longerons. Par ailleurs, l'utilisation de lames à ressort minces par principe apporte les mêmes avantages que ceux énumérés ci-dessus à propos du premier mode d'exécution du fermoir et le lecteur est renvoyé à ce texte.The present invention therefore proposes at least two spring blades to equip each of the longitudinal members fitted to the leaflet and not a single blade for the sake of ensuring good rigidity to said leaflet and thus to avoid buckling of the side members. On the other hand, the use of thin spring blades in principle provides the same advantages as those enumerated above with respect to the first embodiment of the clasp and the reader is referred to this text.

On va décrire maintenant le mécanisme de verrouillage et de déverrouillage mis en oeuvre respectivement pour accrocher et décrocher le dépliant 33 sur et de l'élément de base 30. Les figures 7 et 9 montrent que ce mécanisme est composé de premier 40 et second 41 crochets portés respectivement vers l'extrémité libre 49 des premier 31 et second 32 bras rigides. Lesdits premier 40 et second 41 crochets sont arrangés pour être verrouillés respectivement par des premier 42 et second 43 verrous portés respectivement par lesdits premier 34 et second 35 longerons vers l'extrémité libre des lames à ressort les constituant.We will now describe the locking and unlocking mechanism used respectively for hooking and unhooking the leaflet 33 on and the base element 30. figures 7 and 9 show that this mechanism is composed of first 40 and second 41 hooks respectively carried towards the free end 49 of the first 31 and second 32 rigid arms. Said first 40 and second 41 hooks are arranged to be locked respectively by first 42 and second 43 latches respectively by said first 34 and second longitudinal members towards the free end of the spring blades constituting them.

On comprendra qu'une pression latérale exercée sur chacun des longerons 34 et 35 rapprochera les verrous 42 et 43 et les dégageront respectivement des crochets 40 et 41 portés par les bras rigides 31 et 32 de l'élément de base 30 (voir figure 9). Le fermoir est alors en voie d'ouverture. Pour favoriser l'action manuelle exercée sur chacun des longerons des premier 45 et second 46 poussoirs sont fixés respectivement sur lesdits premier 34 et second 35 longerons.It will be understood that lateral pressure exerted on each of the longitudinal members 34 and 35 will bring the latches 42 and 43 closer together and disengage them respectively from the hooks 40 and 41 carried by the rigid arms 31 and 32 of the base element 30 (see FIG. figure 9 ). The clasp is then in the process of opening. To promote the manual action exerted on each of the longitudinal members of the first 45 and second 46 pushers are respectively fixed on said first 34 and second 35 longitudinal members.

Les lames à ressort 36, 37 composant le premier longeron 34 et les lames à ressort 38, 39 composant le second longeron 35 peuvent être montées jointives et les dessins ne font pas état de cette construction. Ici les figures montrent que ces lames sont séparées par des entretoises solides désignées par 47 pour celles qui séparent les lames à ressort à leur articulation sur l'élément de base 30 et par 51 pour celles qui séparent lesdites lames à ressort à leur extrémité libre. On évite de cette façon des problèmes que peuvent présenter le frottement et la corrosion entre les lames, comme cela a déjà été dit à propos du premier mode d'exécution. On notera qu'ici aussi, l'espace laissé libre entre les lames à ressort pourrait être comblé par un matériau mou, par exemple du caoutchouc.The spring blades 36, 37 making up the first spar 34 and the spring blades 38, 39 composing the second spar 35 can be mounted contiguous and the drawings do not mention this construction. Here the figures show that these blades are separated by solid spacers designated 47 for those which separate the spring blades at their articulation on the base member 30 and 51 for those which separate said spring blades at their free end. This avoids problems that can present friction and corrosion between the blades, as has already been said about the first embodiment. Note that here too, the space left free between the spring blades could be filled by a soft material, for example rubber.

Plusieurs constructions peuvent être envisagées pour équiper l'extrémité libre de chacun des longerons qui comprend un poussoir, deux lames à ressort, une entretoise et un verrou. Les figures 6 et 7 proposent une de ces constructions. Ici une entretoise allongée 51 est prise en sandwich entre les lames à ressort 36 et 37 formant le longeron 34. Fait d'une pièce avec l'entretoise 51 on trouve le verrou 42 susceptible d'être retenu par le crochet 40 porté par le bras rigide 31 de l'élément de base 30. Le poussoir 45 est fixé au longeron 34 sur la face extérieure de la première lame à ressort 36 par l'intermédiaire de vis 52 vissées dans une contrepièce 53 appliquée sur la face extérieure de la seconde lame à ressort 37. La même construction est adoptée pour le longeron 35.Several constructions can be envisaged to equip the free end of each of the longitudinal members which comprises a pusher, two spring blades, a spacer and a lock. The Figures 6 and 7 propose one of these constructions. Here an elongate spacer 51 is sandwiched between the spring blades 36 and 37 forming the spar 34. Made of a piece with the spacer 51 there is the latch 42 may be retained by the hook 40 carried by the arm rigid 31 of the base member 30. The pusher 45 is fixed to the beam 34 on the outer face of the first leaf spring 36 by screws 52 screwed into a counterpart 53 applied on the outer face of the second leaf spring 37. The same construction is adopted for the spar 35.

On mentionnera encore qu'à l'extrémité libre 48 du dépliant 33 est fixé un premier brin du bracelet, notamment le brin des 12 heures si le bracelet est attaché à une montre. Ici la fixation se fera par exemple au moyen d'une barrette traversant des trous 54 percés à l'extrémité des entretoises 51.Note also that at the free end 48 of the leaflet 33 is fixed a first strand of the bracelet, including the strand of 12 hours if the bracelet is attached to a watch. Here the fixing will be done for example by means of a bar passing through holes 54 drilled at the end of the spacers 51.

De même à l'extrémité libre 49 de l'élément de base 30 est disposé un pont 55 qui relie les premier 31 et second 32 bras rigides, pont sur lequel est fixé un téton 56 destiné à recevoir un second brin du bracelet, notamment le brin de 6 heures muni de perforation cette fixation permettant de surcroît le réglage de la longueur du bracelet.Likewise at the free end 49 of the base member 30 is disposed a bridge 55 which connects the first 31 and second 32 rigid arms, bridge on which is fixed a pin 56 for receiving a second strand of the bracelet, including the 6 hour strand with perforation this fixation allowing moreover the adjustment of the length of the bracelet.
