Definitions
- the present invention relates to a clasp for assembling two flexible strands, for example leather or a synthetic material.
- a clasp can be used by example, for a watch strap or a belt.
- the strands have holes for receiving a barb during assembly.
- This conventional construction has the disadvantage that said strands break easily, usually at the location of the hole receiving the barb, due to fatigue which these strands are subjected.
- bracelets especially those that are suitable for watches, ask to be closed on the wrist with ease and without running the risk that the watch may escape when trying to form the loop of closing. For this reason, the bracelet can be continuous so that it arises sure on the wrist.
- a first known solution relates to bracelets made of segments contiguous metal that contains small springs that extend the bracelet when you pull on it. Such a solution, to be feasible, however requires very small springs subject to fatigue and that have a life time limited.
- hinged clasps have been proposed. multiple articulated, these clasps being essentially mounted on bracelets two-segment metal hinged but not extensible. This solution more advantage has been obtained with continuous devices with rigid segments, articulated, foldable, stackable and hooked to each other. There is a big one number of models.
- An example is a model with three rigid segments whose first comes to close under the second, while the third, serving as cover, engages on the second and hangs on the first.
- This device consists of a clasp attached to one of the strands of a bracelet and provided with means ensuring the tightening of the other strand of the bracelet.
- This second strand is clamped between the base of the clasp and an eccentric end of a lever pivoting on the base of this clasp.
- the base plate of this clasp carries a rib that comes engage in one of the furrows practiced on the invisible face of the bracelet intended for to be in contact with the wrist of the wearer of the watch.
- Said base plate carries in addition a lug which engages in one of said grooves on the face invisible bracelet.
- An advantage of this clasp lies in the fact that, in the embodiment described above, the second strand is engaged under the first strand, which gives a very aesthetic appearance to the bracelet.
- This clasp also has for advantage of being able to be adapted to all types of flexible bracelets, for example Milanese or woven, or made of plastic.
- the clasp described in document CH 530.189 has a certain number of disadvantages, foremost among which are the fact that the lever swivel which closes by its eccentric end the second strand of the bracelet against the base of the clasp does not ensure a secure subjection of the bracelet to the wrist that door. Indeed, an external tearing force can very easily rotate the lever in the open position and pass the bracelet on the hand without this action be desired by the wearer. This way of doing so diminishes the confidence that we can have in this kind of clasp.
- the base plate of the clasp carries both a rib and a lug that each engage in one of the furrows practiced on the underside of the bracelet. Since nothing is planned to lift the bracelet in order to free the furrows from their grip with the rib and the spur, the wearer goes encounter significant difficulties to scroll the second strand off the clasp when he wants to leave his watch. This operation is made all the more delicate that the bracelet is engaged with the base plate, not at a point, but in two distinct points materialized by the rib and the ergot.
- Patent CH 454,513 for its part describes a watchband comprising a clasp secured to one of the strands of the bracelet and provided with means ensuring the tightening the other strand of the bracelet.
- the clamping means are formed by a slightly curved plate, having a bottom provided on each side, in the direction parallel to the length of the bracelet, a perpendicular edge.
- a rod fixed in the edges ensures the connection of the clasp with one of the strands of the bracelet.
- a cover is hinged on the clamping means and pivots around the same rod as that by which the clasp is connected to one of the strands.
- the lid presents each side, in the longitudinal direction to the length of the bracelet, a flange.
- the plate has a projection directed towards the top that is engaged in one of the furrows in the invisible lower face the second strand of the bracelet. With the lid open, the end of the second strand in an opening that presents the clasp. We then adjust the second strand to the desired length, then engage the projection in one of the furrows. Finally, we fold the lid.
- This form of execution has the major disadvantage of wearing out quickly and not to ensure a good notch of the cover on the edges of the plate of the clasp. This is mainly due to a high notching force and hence to a rapid wear of the system. But if the lid of the clasp is not properly closed, an external tearing force can very easily rotate it, from so that the user risks losing his watch.
- the present invention aims to overcome the above drawbacks as well as others by offering a clasp to assemble two strands flexible, usable for example for a watch strap or a belt, this clasp being inexpensive to produce and presenting a great ease and safety of use.
- the present invention relates to a clasp for assembling a first and second flexible strands comprising a loop attached to the first of the two strands while the second strand enters the loop, the loop comprising fixed hooking means which hang in the second strand, and comprising an actuatable unlocking device manually, characterized in that the unlocking device allows to lift the second strand to release it from the hooking means and to scroll it out of the loop.
- the present invention provides an easy clasp to use. Indeed, to assemble the flexible strands of the bracelet or the belt and close the clasp, simply engage the end of the second strand in the clasp, so that this end is placed above the attachment means. We then adjust the strand of the bracelet to the desired length, then the hooking means come hang on in this strand. The bracelet is thus firmly held in place and therefore does not risk opening unexpectedly. To open the bracelet, it's just necessary to manually operate the unlocking device. In doing so, the unlocking device raises the second strand of the wristband to release it from means of attachment, so that the wearer only has to pull on this strand for the drag from the first strand and release it from the loop.
- the clasp according to the invention also offers great security of operation. Indeed, as described above, when the means snap hook in the second strand, it is impossible to pull the second strand back.
- the confidence that we can have in the clasp according to the invention is further increased by the fact that this clasp does not require any parts for tighten or pinch the second strand of the bracelet to immobilize it. Therefore, the user is not likely to lose his watch as is the case with the clasps of the prior art provided with clamping or pinching parts that can open untimely at any time.
- the means latching means comprise a tooth
- the unlocking device comprises a lever mounted movably on the buckle and which is able to lift the second strand.
- the clasp according to the invention therefore comprises only two parts, namely the buckle itself that carries a tooth that hangs in the second strand and which, at choice, can be made from a piece with the buckle or constitute a piece the buckle, and the unlocking device that allows the user to lift the strand to release it from the tooth.
- the buckle itself that carries a tooth that hangs in the second strand and which, at choice, can be made from a piece with the buckle or constitute a piece the buckle, and the unlocking device that allows the user to lift the strand to release it from the tooth.
- clasp according to the invention is very simple to use, it also has the advantage of not using as a small number of parts and thus be inexpensive to manufacture.
- the present invention proceeds from the general inventive idea of provide a clasp to assemble the two strands of a bracelet or belt that simple to use and reliable operation, and also inexpensive to manufacture.
- the clasp according to the invention comprises on the one hand means hanging on the free end of the bracelet or belt to be assembled with the strand attached to the clasp, so that both strands are securely held in place, without the risk of one of the strands moving by report to the other.
- the clasp according to the invention comprises a device for unlocking which advantageously allows to lift the free end to release it hooking means. The wearer of the bracelet or the belt can thus easily scroll the second strand out of the loop when he wants to leave, by example, his watch.
- the present clasp is constituted only two pieces and is therefore inexpensive to manufacture. In addition, it does not has no pinch or blocking member to hold the strands assembled, which constitutes a decisive advantage with regard to the clasps of art prior art, insofar as this type of locking device is susceptible, under the effect an external tearing force, to open without the user desires.
- FIGS. 1 to 4 A first embodiment of the invention is shown in FIGS. 1 to 4 and a second embodiment in FIGS. 4 to 8.
- the figures illustrate a bracelet partially represented, approximately at the opposite place to the watch, if bracelet is intended for a watch.
- the bracelet is intended to be worn mainly around the wrist and has a first flexible strand 1 and a second flexible strand 2 whose first ends (not shown) are attached to the watch.
- the present invention will therefore be described with reference to a watch. he goes however, of course, the present invention applies identically to a belt, a bracelet with a jewel, or any other type of bracelet whose ends can be joined by a clasp according to the invention.
- a clasp according to the present invention designated as a whole by the general reference numeral 4, essentially consists of a loop 6 attached to the first flexible strand 1, while that the second flexible strand 2 enters the loop 6 to be assembled at the first strand 1.
- loop 6 comprises two plates 8 parallel to each other and extending from other first and second strands 1 and 2, in a longitudinal direction to the length of the strands 1 and 2.
- the two plates 8 are connected at their ends by two transverse crosspieces 10 audits flexible strands 1 and 2.
- the loop 6 presents means fastening hooks 14 which hang in the second flexible strand 2. These fastening means 14 prevent removal of said second strand 2 when the latter is engaged in the loop 6, this to firmly fasten the wristband to the wrist The door.
- the means fastening 14 are in the form of a tooth 16 carried by a rib 18 which extends between the two plates 8 of the loop 6, perpendicular to them.
- the tooth 16, the rib 18 which the door and the two plates 8 of the loop 16 can be made in one piece, for example by molding or by injection of a plastic or metal material.
- the tooth 16 and its rib 18 are manufactured so separated and fixed between the plates 8 of the loop 16 by any appropriate means, for example example by gluing, ultrasonic welding or by screwing.
- the means of attachment could be, for example, a small hook or still in a nipple (not shown).
- the end portion 19 of the second strand 2 has on its invisible lower face in view of the wearer at least one milling forming transverse groove 20 extending over part of the total width of the bracelet.
- This groove 20 has, for example, the shape shown in Figures 2 and 3, that is to say the shape of a section groove substantially triangular.
- the tooth 16 carried by the loop 6 penetrates by its upper end into the groove 20 so as to block the second strand 2 safely, since no force outside tearing can not pass the object on the hand without this action be desired by the wearer.
- the security of the clasp 4 according to the invention is further increased by the fact that the tooth 16 is at a higher level than the upper face of the first strand 1.
- the second strand 2 which is introduced in the loop 2 and has a path curve which makes it pass above said tooth 16, so that, when released the second strand 2 and the wrist of the wearer relaxes, this causes the displacement said second strand 2 in the opening direction, which has the effect of tending the second strand 2 and to further firmly engage the tooth 16 in the groove 20 or the hole with which said tooth 16 is engaged.
- Figures 2 and 3 show a plurality of grooves 20 (here four) made in the second flexible strand 2 and arranged in a row on a part of the total length of said second strand 2.

Abstract
Description
La présente invention concerne un fermoir pour assembler deux brins souples, par exemple en cuir ou en une matière synthétique. Un tel fermoir peut être utilisé, par exemple, pour un bracelet de montre ou une ceinture.The present invention relates to a clasp for assembling two flexible strands, for example leather or a synthetic material. Such a clasp can be used by example, for a watch strap or a belt.
Dans les dispositifs connus de fermoirs pour assembler des brins souples, les brins comportent des trous prévus pour recevoir un ardillon lors de leur assemblage. Cette construction classique a cependant le désavantage que lesdits brins cassent facilement, en général à l'endroit du trou qui reçoit l'ardillon, en raison de la fatigue à laquelle ces brins sont soumis.In the known devices of clasps for assembling flexible strands, the strands have holes for receiving a barb during assembly. This conventional construction, however, has the disadvantage that said strands break easily, usually at the location of the hole receiving the barb, due to fatigue which these strands are subjected.
Or, les bracelets, particulièrement ceux qui sont adaptés aux montres, demandent à pouvoir être refermés sur le poignet avec facilité et sans faire courir le risque que la montre puisse s'échapper quand on cherche à former la boucle de fermeture. Pour cette raison, le bracelet peut être continu pour qu'il se pose de façon sûre sur le poignet.Now bracelets, especially those that are suitable for watches, ask to be closed on the wrist with ease and without running the risk that the watch may escape when trying to form the loop of closing. For this reason, the bracelet can be continuous so that it arises sure on the wrist.
Une première solution connue se rapporte à des bracelets faits de segments métalliques contigus qui contiennent de petits ressorts qui permettent d'allonger le bracelet lorsqu'on exerce une traction sur lui. Une telle solution, pour être réalisable, exige cependant des ressorts très petits sujets à la fatigue et qui ont une durée de vie limitée.A first known solution relates to bracelets made of segments contiguous metal that contains small springs that extend the bracelet when you pull on it. Such a solution, to be feasible, however requires very small springs subject to fatigue and that have a life time limited.
Pour remédier à cet inconvénient, on a proposé des fermoirs à charnières multiples articulées, ces fermoirs étant essentiellement montés sur bracelets métalliques à deux segments articulés mais non extensibles. Cette solution plus avantageuse a été obtenue avec des dispositifs continus à segments rigides, articulés, repliables, superposables et accrochés l'un à l'autre. Il en existe un grand nombre de modèles.To remedy this drawback, hinged clasps have been proposed. multiple articulated, these clasps being essentially mounted on bracelets two-segment metal hinged but not extensible. This solution more advantage has been obtained with continuous devices with rigid segments, articulated, foldable, stackable and hooked to each other. There is a big one number of models.
On peut citer comme exemple un modèle à trois segments rigides dont le premier vient se refermer sous le second, pendant que le troisième, servant de couverture, s'engage sur le second et se bloque sur le premier.An example is a model with three rigid segments whose first comes to close under the second, while the third, serving as cover, engages on the second and hangs on the first.
Ces fermoirs classiques à boucle dépliante ont pour avantage de permettre d'éviter, dans une certaine mesure, que le bracelet ne passe subrepticement par dessus la main si une force d'arrachement est exercée sur le bracelet. Cependant, ce genre de fermoir est relativement compliqué, met en oeuvre de nombreuses pièces, ce qui lui confère un coût assez élevé. These classic clasps with folding buckle have the advantage of allowing to prevent, to a certain extent, the bracelet from surreptitiously passing through above the hand if a pulling force is exerted on the bracelet. However, this kind of clasp is relatively complicated, implements many pieces, which gives it a fairly high cost.
Une amélioration notable a été apportée par le dispositif décrit dans le document CH 530,189 où a été proposée une construction qui, en même temps qu'elle propose une meilleure esthétique, améliore la facilité de fermeture.A significant improvement has been made by the device described in the document CH 530,189 where a construction was proposed which, at the same time that it offers a better aesthetic, improves the ease of closing.
Ce dispositif est constitué d'un fermoir solidaire de l'un des brins d'un bracelet et pourvu de moyens assurant le serrage de l'autre brin du bracelet. Ce second brin est serré entre la base du fermoir et une extrémité excentrique d'un levier pivotant sur la base de ce fermoir. La plaque de base de ce fermoir porte une nervure qui vient s'engager dans l'un des sillons pratiqués sur la face invisible du bracelet destinée à être en contact avec le poignet du porteur de la montre. Ladite plaque de base porte en outre un ergot qui vient s'engager dans un desdits sillons pratiqués sur la face invisible du bracelet.This device consists of a clasp attached to one of the strands of a bracelet and provided with means ensuring the tightening of the other strand of the bracelet. This second strand is clamped between the base of the clasp and an eccentric end of a lever pivoting on the base of this clasp. The base plate of this clasp carries a rib that comes engage in one of the furrows practiced on the invisible face of the bracelet intended for to be in contact with the wrist of the wearer of the watch. Said base plate carries in addition a lug which engages in one of said grooves on the face invisible bracelet.
Un avantage de ce fermoir réside dans le fait que, dans la forme d'exécution décrite ci-dessus, le second brin vient s'engager sous le premier brin, ce qui donne un aspect très esthétique au bracelet.An advantage of this clasp lies in the fact that, in the embodiment described above, the second strand is engaged under the first strand, which gives a very aesthetic appearance to the bracelet.
Un autre avantage est la grande simplicité de construction du fermoir qui permet de réduire sensiblement ses coûts de fabrication. Ce fermoir a aussi pour avantage de pouvoir être adapté à tous types de bracelets souples, par exemple du genre milanais ou tissés, ou bien encore réalisés en matière plastique.Another advantage is the great simplicity of construction of the clasp that significantly reduces its manufacturing costs. This clasp also has for advantage of being able to be adapted to all types of flexible bracelets, for example Milanese or woven, or made of plastic.
Le fermoir décrit dans le document CH 530,189 présente cependant un certain nombre d'inconvénients au premier rang desquels on peut citer le fait que le levier pivotant qui serre par son extrémité excentrique le second brin du bracelet contre la base du fermoir n'assure pas un assujettissement sûr du bracelet sur le poignet qui le porte. En effet, une force d'arrachement extérieure peut très facilement faire pivoter le levier en position d'ouverture et faire passer le bracelet sur la main sans que cette action soit voulue par le porteur. Cette façon de faire diminue ainsi la confiance que l'on peut avoir dans ce genre de fermoir.The clasp described in document CH 530.189, however, has a certain number of disadvantages, foremost among which are the fact that the lever swivel which closes by its eccentric end the second strand of the bracelet against the base of the clasp does not ensure a secure subjection of the bracelet to the wrist that door. Indeed, an external tearing force can very easily rotate the lever in the open position and pass the bracelet on the hand without this action be desired by the wearer. This way of doing so diminishes the confidence that we can have in this kind of clasp.
D'autre part, comme on l'a décrit ci-dessus, ia piaque de base du fermoir porte à la fois une nervure et un ergot qui chacun s'engagent dans un des sillons pratiqués sur la face inférieure du bracelet. Comme rien n'est prévu pour soulever le bracelet afin de libérer les sillons de leur prise avec la nervure et l'ergot, le porteur va rencontrer d'importantes difficultés pour faire défiler le second brin hors du fermoir lorsqu'il voudra quitter sa montre. Cette opération est rendue d'autant plus délicate que le bracelet est en prise avec la plaque de base, non pas en un point, mais en deux points distincts matérialisés par la nervure et l'ergot.On the other hand, as described above, the base plate of the clasp carries both a rib and a lug that each engage in one of the furrows practiced on the underside of the bracelet. Since nothing is planned to lift the bracelet in order to free the furrows from their grip with the rib and the spur, the wearer goes encounter significant difficulties to scroll the second strand off the clasp when he wants to leave his watch. This operation is made all the more delicate that the bracelet is engaged with the base plate, not at a point, but in two distinct points materialized by the rib and the ergot.
Enfin, en serrant le bracelet contre la plaque de base du fermoir, le levier à excentrique a pour effet de marquer la surface de ce bracelet. Finally, by tightening the bracelet against the base plate of the clasp, the lever to Eccentric has the effect of marking the surface of this bracelet.
Le brevet CH 454,513 décrit pour sa part un bracelet de montre comprenant un fermoir solidaire de l'un des brins du bracelet et muni de moyens assurant le serrage de l'autre brin du bracelet. Les moyens de serrage sont formés par une plaque légèrement incurvée, présentant un fond muni de chaque côté, dans la direction parallèle à la longueur du bracelet, d'un rebord perpendiculaire. Une tige fixée dans les rebords assure la liaison du fermoir avec l'un des brins du bracelet. Un couvercle est articulé sur les moyens de serrage et pivote autour de la même tige que celle par laquelle le fermoir est relié à l'un des brins. Le couvercle présente de chaque côté, dans la direction longitudinale à la longueur du bracelet, un rebord. Ces rebords sont légèrement inclinés vers l'intérieur, comme les rebords de la plaque, de sorte que lorsqu'on rabat le couvercle, il faut vaincre une certaine résistance, ce qui empêche une ouverture intempestive du couvercle. La plaque présente une saillie dirigée vers le haut que l'on engage dans l'un des sillons ménagés dans la face inférieure invisible du second brin du bracelet. Le couvercle étant ouvert, on engage l'extrémité du second brin dans une ouverture que présente le fermoir. On règle ensuite le second brin à la longueur voulue, puis on engage la saillie dans l'un des sillons. Enfin, on rabat le couvercle.Patent CH 454,513 for its part describes a watchband comprising a clasp secured to one of the strands of the bracelet and provided with means ensuring the tightening the other strand of the bracelet. The clamping means are formed by a slightly curved plate, having a bottom provided on each side, in the direction parallel to the length of the bracelet, a perpendicular edge. A rod fixed in the edges ensures the connection of the clasp with one of the strands of the bracelet. A cover is hinged on the clamping means and pivots around the same rod as that by which the clasp is connected to one of the strands. The lid presents each side, in the longitudinal direction to the length of the bracelet, a flange. These edges are slightly inclined inwards, like the edges of the plate, so that when you fold down the lid, you have to overcome some resistance, which prevents inadvertent opening of the lid. The plate has a projection directed towards the top that is engaged in one of the furrows in the invisible lower face the second strand of the bracelet. With the lid open, the end of the second strand in an opening that presents the clasp. We then adjust the second strand to the desired length, then engage the projection in one of the furrows. Finally, we fold the lid.
Cette forme d'exécution a comme inconvénient majeur de s'user rapidement et de ne plus assurer un bon crantage du couvercle sur les rebords de la plaque du fermoir. Ceci est dû essentiellement à une force de crantage élevée et, partant, à une usure rapide du système. Or, si le couvercle du fermoir n'est pas convenablement fermé, une force d'arrachement extérieure peut très facilement le faire pivoter, de sorte que l'usager risque de perdre sa montre.This form of execution has the major disadvantage of wearing out quickly and not to ensure a good notch of the cover on the edges of the plate of the clasp. This is mainly due to a high notching force and hence to a rapid wear of the system. But if the lid of the clasp is not properly closed, an external tearing force can very easily rotate it, from so that the user risks losing his watch.
D'autre part, rien n'est prévu pour soulever le second brin du bracelet sous la face inférieure duquel sont ménagés les sillons dans lesquels la saillie que présente la plaque vient s'engager. L'utilisateur risque donc d'éprouver de grandes difficultés pour faire glisser les deux brins du bracelet l'un par rapport à l'autre, car l'un des brins risque d'être retenu par la saillie en prise avec le sillon correspondant.On the other hand, nothing is planned to lift the second strand of the bracelet under the underside of which are formed grooves in which the projection that presents the plate comes to engage. The user may therefore have great difficulty in slide the two strands of the bracelet relative to each other because one of the strands risk of being held by the projection in engagement with the corresponding groove.
La présente invention a pour but de remédier aux inconvénients ci-dessus ainsi qu'à d'autres encore en proposant un fermoir pour assembler deux brins souples, utilisable par exemple pour un bracelet de montre ou une ceinture, ce fermoir étant peu coûteux à réaliser et présentant une grande facilité et sûreté d'emploi.The present invention aims to overcome the above drawbacks as well as others by offering a clasp to assemble two strands flexible, usable for example for a watch strap or a belt, this clasp being inexpensive to produce and presenting a great ease and safety of use.
A cet effet, la présente invention concerne un fermoir pour assembler un premier et un second brins souples comprenant une boucle rattachée au premier des deux brins tandis que le second brin pénètre dans la boucle, la boucle comprenant des moyens d'accrochage fixes qui viennent s'accrocher dans le second brin, et comprenant un dispositif de déverrouillage actionnable manuellement, caractérisé en ce que ce dispositif de déverrouillage permette de soulever le second brin pour le dégager des moyens d'accrochage et le faire défiler hors de la boucle.For this purpose, the present invention relates to a clasp for assembling a first and second flexible strands comprising a loop attached to the first of the two strands while the second strand enters the loop, the loop comprising fixed hooking means which hang in the second strand, and comprising an actuatable unlocking device manually, characterized in that the unlocking device allows to lift the second strand to release it from the hooking means and to scroll it out of the loop.
Grâce à ces caractéristiques, la présente invention procure un fermoir facile à utiliser. En effet, pour assembler les brins souples du bracelet ou de la ceinture et fermer le fermoir, il suffit d'engager l'extrémité du second brin dans le fermoir, de sorte que cette extrémité vient se placer au dessus des moyens d'accrochage. On règle ensuite le brin du bracelet à la longueur voulue, puis les moyens d'accrochage viennent s'accrocher dans ce brin. Le bracelet est ainsi solidement maintenu en place et ne risque donc pas de s'ouvrir intempestivement. Pour ouvrir le bracelet, il est juste nécessaire d'actionner manuellement le dispositif de déverrouillage. Ce faisant, le dispositif de déverrouillage soulève le second brin du bracelet pour le dégager des moyens d'accrochage, de sorte que le porteur n'a plus qu'à tirer sur ce brin pour le faire glisser par rapport au premier brin et le dégager de la boucle.Thanks to these features, the present invention provides an easy clasp to use. Indeed, to assemble the flexible strands of the bracelet or the belt and close the clasp, simply engage the end of the second strand in the clasp, so that this end is placed above the attachment means. We then adjust the strand of the bracelet to the desired length, then the hooking means come hang on in this strand. The bracelet is thus firmly held in place and therefore does not risk opening unexpectedly. To open the bracelet, it's just necessary to manually operate the unlocking device. In doing so, the unlocking device raises the second strand of the wristband to release it from means of attachment, so that the wearer only has to pull on this strand for the drag from the first strand and release it from the loop.
Le fermoir selon l'invention offre également une grande sécurité de fonctionnement. Effectivement, comme décrit ci-dessus, lorsque les moyens d'accrochage viennent s'accrocher dans le second brin, il est impossible de tirer le second brin en arrière. La confiance que l'on peut avoir dans le fermoir selon l'invention est encore accrue par le fait que ce fermoir ne nécessite aucune pièce pour serrer ou pincer le second brin du bracelet afin de l'immobiliser. Par conséquent, l'utilisateur ne risque pas de perdre sa montre comme tel est le cas avec les fermoirs de l'art antérieur munis de pièces de serrage ou de pincement pouvant s'ouvrir intempestivement à tout instant.The clasp according to the invention also offers great security of operation. Indeed, as described above, when the means snap hook in the second strand, it is impossible to pull the second strand back. The confidence that we can have in the clasp according to the invention is further increased by the fact that this clasp does not require any parts for tighten or pinch the second strand of the bracelet to immobilize it. Therefore, the user is not likely to lose his watch as is the case with the clasps of the prior art provided with clamping or pinching parts that can open untimely at any time.
Selon une caractéristique complémentaire de l'invention, les moyens d'accrochage comprennent une dent, et le dispositif de déverrouillage comprend un levier monté de manière mobile sur la boucle et qui est capable de soulever le second brin.According to a complementary characteristic of the invention, the means latching means comprise a tooth, and the unlocking device comprises a lever mounted movably on the buckle and which is able to lift the second strand.
Le fermoir selon l'invention ne comprend donc que deux pièces, à savoir la boucle proprement dite qui porte une dent qui vient s'accrocher dans le second brin et qui, au choix, peut être faite d'une pièce avec la boucle ou constituer une pièce séparée qui sera fixée sur la boucle, et le dispositif de déverrouillage qui permet à l'utilisateur de soulever le brin afin de le dégager de la dent. Outre le fait que le fermoir selon l'invention est très simple à utiliser, il présente aussi l'intérêt de n'utiliser qu'un faible nombre de pièces et d'être ainsi peu coûteux à fabriquer.The clasp according to the invention therefore comprises only two parts, namely the buckle itself that carries a tooth that hangs in the second strand and which, at choice, can be made from a piece with the buckle or constitute a piece the buckle, and the unlocking device that allows the user to lift the strand to release it from the tooth. Besides the fact that clasp according to the invention is very simple to use, it also has the advantage of not using as a small number of parts and thus be inexpensive to manufacture.

La présente invention procède de l'idée générale inventive qui consiste à procurer un fermoir pour assembler les deux brins d'un bracelet ou d'une ceinture qui soit simple à utiliser et d'un fonctionnement fiable, et qui soit également peu coûteux à fabriquer. A cet effet, le fermoir selon l'invention comprend d'une part des moyens d'accrochage qui viennent s'accrocher dans le brin libre du bracelet ou de la ceinture à assembler avec le brin attaché au fermoir, de façon que les deux brins soient solidement maintenus en place, sans risque de voir l'un des brins se déplacer par rapport à l'autre. D'autre part, le fermoir selon l'invention comprend un dispositif de déverrouillage qui permet avantageusement de soulever le brin libre afin de le libérer des moyens d'accrochage. Le porteur du bracelet ou de la ceinture peut ainsi facilement faire défiler le second brin hors de la boucle lorsqu'il veut quitter, par exemple, sa montre. Enfin, il faut noter que le présent fermoir est constitué seulement de deux pièces et est par conséquent peu coûteux à fabriquer. En outre, il ne présente pas d'organe de pincement ou de blocage pour maintenir les brins assemblés, ce qui constitue un avantage décisif au regard des fermoirs de l'art antérieur, dans la mesure où ce type d'organe de blocage est susceptible, sous l'effet d'une force d'arrachement extérieure, de s'ouvrir sans que l'utilisateur ne le désire.The present invention proceeds from the general inventive idea of provide a clasp to assemble the two strands of a bracelet or belt that simple to use and reliable operation, and also inexpensive to manufacture. For this purpose, the clasp according to the invention comprises on the one hand means hanging on the free end of the bracelet or belt to be assembled with the strand attached to the clasp, so that both strands are securely held in place, without the risk of one of the strands moving by report to the other. On the other hand, the clasp according to the invention comprises a device for unlocking which advantageously allows to lift the free end to release it hooking means. The wearer of the bracelet or the belt can thus easily scroll the second strand out of the loop when he wants to leave, by example, his watch. Finally, it should be noted that the present clasp is constituted only two pieces and is therefore inexpensive to manufacture. In addition, it does not has no pinch or blocking member to hold the strands assembled, which constitutes a decisive advantage with regard to the clasps of art prior art, insofar as this type of locking device is susceptible, under the effect an external tearing force, to open without the user desires.
Un premier mode d'exécution de l'invention est montré aux figures 1 à 4 et un
second mode d'exécution aux figures 4 à 8. Dans les deux cas, les figures illustrent
un bracelet représenté partiellement, environ à l'endroit opposé à la montre, si ce
bracelet est destiné à une montre. Dans ces deux cas, le bracelet est destiné à être
porté principalement autour du poignet et comporte un premier brin souple 1 et un
second brin souple 2 dont les premières extrémités (non représentées) sont attachées
à la montre.A first embodiment of the invention is shown in FIGS. 1 to 4 and a
second embodiment in FIGS. 4 to 8. In both cases, the figures illustrate
a bracelet partially represented, approximately at the opposite place to the watch, if
bracelet is intended for a watch. In both cases, the bracelet is intended to be
worn mainly around the wrist and has a first
La présente invention va donc être décrite en référence à une montre. Il va toutefois de soi que la présente invention s'applique de manière identique à une ceinture, à un bracelet portant un bijou, ou à tout autre type de bracelet dont les extrémités peuvent être réunies par un fermoir selon l'invention.The present invention will therefore be described with reference to a watch. he goes however, of course, the present invention applies identically to a belt, a bracelet with a jewel, or any other type of bracelet whose ends can be joined by a clasp according to the invention.
Comme représenté sur les figures 1 à 4, un fermoir conforme à la présente
invention, désigné dans son ensemble par la référence numérique générale 4, se
compose essentiellement d'une boucle 6 rattachée au premier brin souple 1, tandis
que le second brin souple 2 pénètre dans la boucle 6 pour être assemblé au premier
brin 1.As represented in FIGS. 1 to 4, a clasp according to the present
invention, designated as a whole by the
Comme on le voit notamment sur la vue en perspective de la figure 1, la
boucle 6 comprend deux plaques 8 parallèles entre elles et s'étendant de part et
d'autre des premier et second brins 1 et 2, dans une direction longitudinale à la
longueur des brins 1 et 2. Pour rigidifier la boucle 6 et lui conférer une bonne
résistance mécanique, les deux plaques 8 sont reliées à leurs extrémités par deux
traverses 10 transversales audits brins souples 1 et 2.As can be seen in particular in the perspective view of FIG.
On voit également sur la figure 1 que l'on a donné aux bords supérieurs 12 des deux plaques 8 une forme cintrée qui épouse la courbure du poignet du porteur.It is also seen in Figure 1 that the upper edges were given 12 two plates 8 a curved shape that matches the curvature of the wearer's wrist.
Conformément à la présente invention, la boucle 6 présente des moyens
d'accrochage fixes 14 qui viennent s'accrocher dans le second brin souple 2. Ces
moyens d'accrochage 14 empêchent le retrait dudit second brin 2 lorsque ce dernier
est engagé dans la boucle 6, cela pour assujettir fermement le bracelet au poignet qui
le porte.According to the present invention, the
Dans le mode d'exécution représenté aux figures 1 à 4, les moyens
d'accrochage 14 se présentent sous la forme d'une dent 16 portée par une nervure 18
qui s'étend entre les deux plaques 8 de la boucle 6, perpendiculairement à celles-ci.
Selon un mode de réalisation particulièrement avantageux, la dent 16, la nervure 18
qui la porte et les deux plaques 8 de la boucle 16 peuvent être faits d'une seule pièce,
par exemple par moulage ou par injection d'une matière plastique ou métallique.
Selon une autre variante, la dent 16 et sa nervure 18 sont fabriquées de manière
séparée et fixés entre les plaques 8 de la boucle 16 par tout moyen approprié, par
exemple par collage, soudage aux ultrasons ou encore par vissage. In the embodiment shown in FIGS. 1 to 4, the means
fastening 14 are in the form of a
On notera que l'invention n'est pas limitée à l'utilisation d'une dent. Les moyens d'accrochage pourraient consister, par exemple, en un petit crochet ou encore en un téton (non représentés).It should be noted that the invention is not limited to the use of a tooth. The means of attachment could be, for example, a small hook or still in a nipple (not shown).
La partie terminale 19 du second brin 2 présente sur sa face inférieure invisible
au regard du porteur au moins un fraisage formant sillon transversal 20 s'étendant sur
une partie de la largeur totale du bracelet. Ce sillon 20 a, par exemple, la forme
montrée sur les figures 2 et 3, c'est-à-dire la forme d'une rainure de section
sensiblement triangulaire.The
La dent 16 portée par la boucle 6 pénètre par son extrémité supérieure dans le
sillon 20 de façon à bloquer le second brin 2 de manière sûre, puisque aucune force
d'arrachement extérieure ne peut faire passer l'objet sur la main sans que cette action
soit voulue par le porteur.The
On notera que la sécurité du fermoir 4 selon l'invention est encore accrue par
le fait que la dent 16 se trouve à un niveau plus élevé qu la face supérieure du
premier brin 1. Le second brin 2 qui est introduit dans la boucle 2 a ainsi un tracé
courbe qui le fait passer au dessus de ladite dent 16, de sorte que, lorsqu'on relâche
le second brin 2 et que le poignet du porteur se détend, cela provoque le déplacement
dudit second brin 2 dans le sens de l'ouverture, ce qui a pour résultat de tendre le
second brin 2 et d'engager plus fermement encore la dent 16 dans le sillon 20 ou le
trou avec lequel ladite dent 16 se trouve en prise.It will be noted that the security of the
Jusqu'ici, il n'a été question que d'un seul sillon 20 pour recevoir la dent 16 de
la boucle 6, ce seul sillon 20 définissant une seule longueur du bracelet lorsque le
second brin 2 est engagé dans ladite boucle 6. On peut cependant désirer plusieurs
longueurs au choix pour s'adapter aux différents pourtours que peut présenter un
poignet. Dans ce but, les figures 2 et 3 montrent une pluralité de sillons 20 (ici quatre)
pratiqués dans le second brin souple 2 et disposés selon une rangée sur une partie
de la longueur totale dudit second brin 2. Ainsi, la dent 16 peut-elle être introduite au
choix dans l'un quelconque des sillons 20 pour adapter la longueur du bracelet au
pourtour du poignet qui le porte.So far, only one
Selon une variante, les sillons 20 peuvent être remplacés par autant de trous
(non représentés) percés dans la partie terminale 19 du second brin 2 et dans
lesquels la dent 16 peut pénétrer pour bloquer ledit second brin 2 en position de
fermeture. On préfèrera cependant réaliser des sillons plutôt que des trous dans le
brin 20 dans la mesure où les sillons 20, pratiqués dans la face inférieure dudit brin
20, sont invisibles au regard du porteur du bracelet.According to one variant, the
Conformément à la présente invention, la boucle 6 comprend également un
dispositif de déverrouillage 22 actionnable manuellement, ce dispositif de
déverrouillage 22 permettant de soulever le second brin 2 pour le dégager des
moyens d'accrochage 14 et le faire défiler hors de la boucle 6. Ainsi, après avoir
actionné le dispositif de déverrouillage 22, le porteur du bracelet n'a plus qu'à tirer sur
le second brin 2 pour le faire glisser par rapport au premier brin 1 et le dégager de la
boucle 6, sans que cette opération ne soit contrariée par la dent 16 susceptible de
rester accrochée dans l'un des sillons 20 ou trous pratiqués dans ledit second brin 2.In accordance with the present invention, the
Le dispositif de déverrouillage 22 se présente sous la forme d'un levier 24
monté de manière mobile sur la boucle 6 et capable de soulever le second brin 2. Ce
levier 24 a une forme ressemblant à celle d'un brancard et se compose d'une barre de
soulèvement 26 du second brin 2 reliée à une plaquette d'actionnement 28 par deux
bras longitudinaux 30. Comme on peut le voir sur les figures 2 et 3, la partie terminale
19 du second brin 2 est passée au dessus de la barre de soulèvement 26, de sorte
qu'il suffit à l'utilisateur d'appuyer légèrement sur la plaquette d'actionnement 28 pour
soulever ledit brin 2. A cet effet, le levier 24 est articulé à pivotement sur la boucle 6
au moyen d'une barrette 32 introduite dans des gonds 34 pratiqués dans l'une et
l'autre plaques 8 de la boucle 6.The unlocking device 22 is in the form of a lever 24
movably mounted on the
Avantageusement, le premier brin 1 est enroulé à longueur fixe autour de la
même barrette 32 que celle par laquelle le levier de déverrouillage 24 est articulé à
pivotement sur la boucle 6.Advantageously, the
Sur la figure 2, le fermoir 4 selon l'invention est représenté à l'état fermé. Le
second brin 2 est engagé par sa partie terminale 19 dans la boucle 6 en le faisant
passer au dessus de la barre de soulèvement 26 du levier de déverrouillage 24. La
dent 16 est engagée dans un des sillons 20 pratiqués dans la face inférieure invisible
du second brin 2. La plaquette d'actionnement 28 présente une partie transversale 36
qui vient buter contre un rebord 38 que présente la traverse 10 en regard, ce qui limite
le débattement du levier de déverrouillage 24.In Figure 2, the
Sur la figure 3, l'utilisateur exerce une poussée sur le levier de déverrouillage
24, ce qui fait pivoter ce levier autour de son axe 32 et provoque la remontée de la
barre de soulèvement 26 qui soulève le second brin souple 2. Les sillons 20 ou trous
pratiqués dans le second brin 2 échappent ainsi à la dent 16 de la boucle 6, et
l'utilisateur peut tirer ledit second brin 2 par rapport au premier brin 1 et le sortir de la
boucle 6.In FIG. 3, the user exerts a push on the unlocking lever
24, which pivots the lever about its
Les figures 5 à 8 illustrent un second mode de réalisation du fermoir 4 selon
l'invention. Dans tout ce qui suit, les éléments identiques à ceux décrits
précédemment seront désignés par les mêmes références numériques.FIGS. 5 to 8 illustrate a second embodiment of
Comme on le voit très clairement, notamment sur les figures 6 et 7, le second
mode de réalisation du fermoir 4 selon l'invention se distingue essentiellement du
premier en ce que le levier de déverrouillage 24 est monté en sens opposé sur la
barrette 32. Ainsi, comme il ressort de la figure 7, l'utilisateur ne doit plus pousser,
mais au contraire tirer sur le levier de déverrouillage 24 pour le faire pivoter autour de
la barrette 32 et soulever le second brin souple 2 qui repose sur la barre de
soulèvement 26. Ce second mode de réalisation se distingue également du premier
en ce que la plaquette d'actionnement 28 présente sous sa surface un logement 40
arrangé pour venir coiffer la traverse 10 de la boucle 6 qui se trouve en regard de ce
logement 40. L'ensemble formé par le logement 40 et la traverse 10 correspondante
est réalisé avec un jeu limité, de sorte qu'il faut vaincre une certaine résistance
lorsqu'on rabat la plaquette d'actionnement 28 sur la traverse 10, ce qui empêche
l'ouverture inopinée du levier de déverrouillage 24.As can be seen very clearly, especially in Figures 6 and 7, the second
embodiment of the
La présente invention peut s'appliquer à tous types de bracelets souples formés de brins par exemple du genre milanais ou tressés, ou réalisés en cuir, en caoutchouc ou en une matière synthétique.The present invention can be applied to all types of flexible bracelets made of strands, for example of the Milanese type or braided, or made of leather, in rubber or a synthetic material.
Il va de soi que l'invention n'est pas limitée aux modes de réalisations qui viennent d'être décrits, et que des modifications et variantes peuvent être envisagées par l'homme du métier sans sortir du cadre de la présente invention.It goes without saying that the invention is not limited to the embodiments which have just been described, and that modifications and variants may be envisaged by those skilled in the art without departing from the scope of the present invention.
