Definitions
- the present invention relates to a device for length adjustment of a bracelet fitted with a clasp folding blades, arranged between two ends of the bracelet, to form with it an endless link whose length can vary between two dimensions, one in which said deploying blades are folded, the other in which they are deployed, including a link of adjustment provided with two parallel articulation axes and transverse to said link, these two axes of articulation being associated respectively with two elements of said link for allow, by pivoting said adjustment link around one of said axes, to invert the respective positions of these two axes of articulation with respect to each other along said link and thus define two determined lengths of this link.
- this adjustment device is to allow the user, to have for each length of the bracelet adjusted by conventional adjustment means, of a determined additional length with a low fixed deviation from the length initially set, in order to allow easy passage without skill or tools particular, from one to the other length of bracelet.
- the distance between these two lengths is chosen to hold account for differences around the wrist depending on the ambient heat and / or according to the efforts that the wearer of the bracelet made with his arm and which result in a swelling of the wrist. Thanks to such a device, it is easy to switch from one length to another determined, depending on whether the bracelet tightens the wrist or on the contrary does not hold enough around the wrist. This is important, in particular but not exclusively, for a watch strap.
- a device of this kind arranged in a clasp to folding clasp, has already been described in CH-A5-663 522.
- the purpose of such a device is to allow two different determined lengths on the bracelet. and of allow the user to choose between these two lengths, by simply rotating the adjustment link between its two positions; this pivoting of the position from longest to shortest setting, being obtained in simply pushing on one of the clasp blades.
- This device however has two drawbacks important, one from a practical point of view, the other on the aesthetically, which therefore take away a lot of its interest.
- the first of these drawbacks is that only when the adjustment link is tilted in its position corresponding to the shortest adjustable length, it is only kept in this position thanks to the clasp closure. As soon as the clasp is open, it returns to the other position, so that when the user puts the bracelet back on, he must ensure that the adjustment link is tilted to the desired position and be careful that it does not change during closing of the clasp.
- the object of the present invention is to remedy, less in part to the aforementioned drawbacks.
- the present invention relates to a device for adjusting the length of a bracelet provided with a folding clasp, of the aforementioned type, according to the claim 1.
- the attached drawing illustrates, schematically and by way of example, an embodiment and variants of the adjustment device object of the present invention.
- Figure 1 is a perspective view of a portion of bracelet provided with this embodiment of the setting.
- Figure 2 is a partial sectional view along the line II-II of figure 1.

- Figure 5 is a partial perspective view of a variant of the adjustment device in the adjustment position long.
- Figure 6 is a partial perspective view of a another variant of this device in the adjustment position short.
- FIGS. 7 and 8 are partial views in perspective, similar to FIGS. 5, respectively 6, of two other variants of this adjustment device.
- the first embodiment of the adjustment device which is the subject of the present invention, illustrated by FIGS. 1 to 4, comprises a metal bracelet with links 1, partially shown, two ends 1a, 1b of which are fixed to a clasp 2 with deploying blades , comprising two blades 2a, 2b, hinged to each other around an axis 3.
- One of these blades, 2a is articulated at the end 1a of the bracelet, while the other end 1b of this bracelet is articulated to a third blade of the clasp 2c provided with two parallel side walls 2c 1 , 2c 2 , forming a cover under which the blades 2a, 2b, fold back.
- the two parallel side walls 2c 1 , 2c 2 , of this cover 2c comprise two respective series of perforations 4 which face each other in pairs, intended to receive a pivot axis 5, called a bar, for fixing the other end 1b of the bracelet and constituting the first usual and known means of adjusting the length of the bracelet.
- a link 6 is pivotally mounted around the axis 5 of the bar fixed in two perforations 4 of the side walls 2c 1 , 2c 2 , of the cover 2c which face each other.
- This link 6 constitutes the link for adjusting the length of the bracelet.
- this adjustment link 6 (FIGS. 2 to 4) comprises a second articulation axis 7 to which is articulated one end of a second link 8, the other end of which is articulated to the rest of the end 1b of the bracelet around an axis 9.
- FIG. 1 As can be seen in particular in FIG.
- this link 8 has a curved blade 8a which is tangent to a portion of cylindrical section 8b coaxial with the articulation axis 7 at one end, while at its other end, this curved blade 8a is folded back to form, with the cylindrical section portion 8b and the blade 8a, a wall 8d, providing a housing 8c intended to receive the adjustment link 6, as illustrated by the Figure 2.
- This wall 8d has an S-shaped profile thus forming a narrowing at the entrance of the housing 8c, the dimension of which is calculated to be slightly less than the corresponding dimension of the part of the adjustment link 6 which must be engage in the logem ent 8c, as seen in particular in FIG. 3.
- This wall 8d therefore serves as a hooking means for the adjustment link 6 when the latter is engaged elastically in this housing 8c.
- FIG. 4 which illustrates the adjustment device in the longest position of the bracelet conferred by this device, the straight line drawn in dashed lines, joining the axes 7 and 9 of the link 8, does not pass either. by the pivot axis 5 of the adjustment link 6.
- the lever arm around the axis 5 tends to produce a torque in the direction F 5 when a force of direction F 6 is exerted on the link 8 (fig. 4), bringing the adjusting link 6 back to the position of figure 2, after having exerted pressure on the link 8 in the direction F 7 (fig. 3) to hook it into the housing 8c.
- the adjustment device makes it possible to choose between two determined bracelet lengths.
- the passage from one position to another is only obtained voluntarily by simple handling, not requiring of particular skill of the user. Once in a position, there is no risk of the length changing involuntarily.
- the length set is also maintained as long as the user has not decided otherwise.
- the clasp can be opened and closed without adjusting be changed. We can also notice that in one or the other of the adjustment positions, the height of the clasp remains practically unchanged, so that this device does not does not harm the aesthetic aspect.
- the wall 8d of the housing 8'c of the link 8 serving as a means of attachment of the adjustment link 6 is constituted by a piece added 8 ', welded to the 8' link.
- This variant allows to make this part 8'd constituting the attachment means elastic specifically for this purpose to get the desired elastic force independently of the 8 'link.
- this 8'd reported item may have another thickness, or even be made of a material different from that of 8 'link. For example, in the case of a gold bracelet, it may be interesting to have a reported item of a other material, for example steel, due to its better elastic properties.
- the 8 * link is in two parts hinged to each other around an axis 10.
- the hooking element of the link setting 6 is then directly constituted by the two parts 8 * d of this link 8 * surrounding the axis 10 around which they are articulated.
- the elasticity of the means 8 * d hooking is only conferred by the curved part 8 * has link 8 *.
- Figures 7 and 8 there is shown two different bracelets, always metallic with articulated links but, as already mentioned, the invention is not limited to a particular type of bracelet.

Description
La présente invention se rapporte à un dispositif de réglage de la longueur d'un bracelet muni d'un fermoir à lames déployantes, disposé entre deux extrémités du bracelet, pour former avec lui un lien sans fin dont la longueur peut varier entre deux dimensions, l'une dans laquelle lesdites lames déployantes sont repliées, l'autre dans laquelle elles sont déployées, comprenant un maillon de réglage muni de deux axes d'articulation parallèles et transversaux audit lien, ces deux axes d'articulation étant associés respectivement à deux éléments dudit lien pour permettre, par pivotement dudit maillon de réglage autour de l'un desdits axes, d'intervertir les positions respectives de ces deux axes d'articulation l'un par rapport à l'autre le long dudit lien et de définir ainsi deux longueurs déterminées de ce lien.The present invention relates to a device for length adjustment of a bracelet fitted with a clasp folding blades, arranged between two ends of the bracelet, to form with it an endless link whose length can vary between two dimensions, one in which said deploying blades are folded, the other in which they are deployed, including a link of adjustment provided with two parallel articulation axes and transverse to said link, these two axes of articulation being associated respectively with two elements of said link for allow, by pivoting said adjustment link around one of said axes, to invert the respective positions of these two axes of articulation with respect to each other along said link and thus define two determined lengths of this link.
Ce dispositif de réglage a pour but de permettre à l'utilisateur, de disposer pour chaque longueur du bracelet réglée par les moyens de réglage conventionnels, d'une longueur supplémentaire déterminée présentant un, faible écart fixe avec la longueur initialement réglée, afin de permettre de passer facilement, sans habileté ni outil particulier, de l'une à l'autre longueur de bracelet. L'écart entre ces deux longueurs est choisi pour tenir compte des différences de pourtour du poignet suivant la chaleur ambiante et/ou suivant les efforts que le porteur du bracelet fait avec son bras et qui se traduisent par un gonflement du poignet. Grâce à un tel dispositif, il est possible de passer facilement de l'une à l'autre des longueurs déterminées, suivant que le bracelet serre le poignet ou au contraire ne tient pas suffisamment autour du poignet. Ceci est important, en particulier mais pas exclusivement, pour un bracelet de montre. The purpose of this adjustment device is to allow the user, to have for each length of the bracelet adjusted by conventional adjustment means, of a determined additional length with a low fixed deviation from the length initially set, in order to allow easy passage without skill or tools particular, from one to the other length of bracelet. The distance between these two lengths is chosen to hold account for differences around the wrist depending on the ambient heat and / or according to the efforts that the wearer of the bracelet made with his arm and which result in a swelling of the wrist. Thanks to such a device, it is easy to switch from one length to another determined, depending on whether the bracelet tightens the wrist or on the contrary does not hold enough around the wrist. This is important, in particular but not exclusively, for a watch strap.
Un dispositif de ce genre, disposé dans un fermoir à boucle déployante, a déjà été décrit dans le CH-A5-663 522. Le but d'un tel dispositif est de permettre de conférer deux longueurs déterminées différentes au bracelet. et de permettre ainsi à l'utilisateur de choisir entre ces deux longueurs, en faisant simplement pivoter le maillon de réglage entre ses deux positions; ce pivotement de la position de réglage la plus longue à la plus courte, étant obtenu en exerçant simplement une poussée sur une des lames du fermoir.A device of this kind, arranged in a clasp to folding clasp, has already been described in CH-A5-663 522. The purpose of such a device is to allow two different determined lengths on the bracelet. and of allow the user to choose between these two lengths, by simply rotating the adjustment link between its two positions; this pivoting of the position from longest to shortest setting, being obtained in simply pushing on one of the clasp blades.
Ce dispositif présente cependant deux inconvénients importants, l'un du point de vue pratique, l'autre sur le plan esthétique, qui lui ôtent de ce fait beaucoup de son intérêt. Le premier de ces inconvénients réside dans le fait que lorsque le maillon de réglage est basculé dans sa position correspondant à la plus courte longueur réglable, il n'est maintenu dans cette position que grâce à la fermeture du fermoir. Dès que le fermoir est oùvert, il revient dans l'autre position, de sorte que lorsque l'utilisateur remet le bracelet, il doit s'assurer que le maillon de réglage est basculé dans la position désirée et faire attention que celle-ci ne change pas pendant la fermeture du fermoir.This device however has two drawbacks important, one from a practical point of view, the other on the aesthetically, which therefore take away a lot of its interest. The first of these drawbacks is that only when the adjustment link is tilted in its position corresponding to the shortest adjustable length, it is only kept in this position thanks to the clasp closure. As soon as the clasp is open, it returns to the other position, so that when the user puts the bracelet back on, he must ensure that the adjustment link is tilted to the desired position and be careful that it does not change during closing of the clasp.
Le second de ces inconvénients vient du fait que l'épaisseur du maillon de réglage s'ajoute à celle des lames du fermoir. Cette surépaisseur est visible et nuit au côté esthétique du fermoir. En outre, cette surépaisseur peut gêner le passage du poignet de la chemise sur le bracelet.The second of these disadvantages comes from the fact that the thickness of the adjustment link is added to that of the blades of the clasp. This extra thickness is visible and harms the side aesthetics of the clasp. In addition, this extra thickness can hinder the passage of the wrist of the shirt on the bracelet.
Il existe, certes, une quantité d'autres dispositifs de réglage de la longueurs des bracelets destinés à permettre au porteur d'en modifier lui-même la longueur. Toutefois, ces dispositifs ne sont généralement pas conçus pour résoudre le problème susmentionné et sont soit trop compliqués, soit ne permettent pas de ne choisir qu'entre deux longueurs déterminées. There are, of course, a number of other adjustment of the lengths of the bracelets intended to allow the bearer can modify the length himself. However, these devices are generally not designed to solve the aforementioned problem and are either too complicated, or do not allow to choose only between two determined lengths.
Le but de la présente invention est de remédier, au moins en partie aux inconvénients susmentionnés.The object of the present invention is to remedy, less in part to the aforementioned drawbacks.
A cet effet, la présente invention a pour objet un dispositif de réglage de la longueur d'un bracelet muni d'un fermoir à lames déployantes, du type susmentionné, selon la revendication 1.To this end, the present invention relates to a device for adjusting the length of a bracelet provided with a folding clasp, of the aforementioned type, according to the claim 1.
Le dessin annexé illustre, schématiquement et à titre d'exemple, une forme d'exécution et des variantes du dispositif de réglage objet de la présente invention.The attached drawing illustrates, schematically and by way of example, an embodiment and variants of the adjustment device object of the present invention.
La figure 1 est une vue en perspective d'une portion de bracelet munie de cette forme d'exécution du dispositif de réglage.Figure 1 is a perspective view of a portion of bracelet provided with this embodiment of the setting.
La figure 2 est une vue partielle en coupe selon la ligne II-II de la figure 1.Figure 2 is a partial sectional view along the line II-II of figure 1.
Les figures 3 et 4 sont des vues en coupe semblables à celle de la figure 2, dans deux autres positions du dispositif de réglage.Figures 3 and 4 are sectional views similar to that of FIG. 2, in two other positions of the adjustment device.
La figure 5 est une vue partielle en perspective d'une variante du dispositif de réglage en position de réglage long.Figure 5 is a partial perspective view of a variant of the adjustment device in the adjustment position long.
La figure 6 est une vue partielle en perspective d'une autre variante de ce dispositif en position de réglage court.Figure 6 is a partial perspective view of a another variant of this device in the adjustment position short.
Les figures 7 et 8 sont des vues partielles en perspective, semblables aux figures 5, respectivement 6, de deux autres variantes de ce dispositif de réglage.Figures 7 and 8 are partial views in perspective, similar to FIGS. 5, respectively 6, of two other variants of this adjustment device.
La première forme d'exécution du dispositif de réglage
objet de la présente invention, illustrée par les figures 1
à 4, comporte un bracelet métallique à maillons 1,
partiellement représenté dont deux extrémités 1a, 1b, sont
fixées à un fermoir 2 à lames déployantes, comprenant deux
lames 2a, 2b, articulées l'une à l'autre autour d'un axe 3.
L'une de ces lames, 2a, est articulée à l'extrémité la du
bracelet, tandis que l'autre extrémité 1b de ce bracelet,
est articulée à une troisième lame du fermoir 2c munie de
deux parois latérales parallèles 2c1, 2c2, formant un capot
sous lequel les lames 2a, 2b, se replient. Les deux parois
latérales parallèles 2c1, 2c2, de ce capot 2c comportent
deux séries de perforations 4 respectives qui se font face
deux à deux, destinées à recevoir un axe de pivotement 5,
appelé barrette, pour la fixation de l'autre extrémité 1b du
bracelet et constituant des premiers moyens de réglage
habituels et connus de la longueur du bracelet.The first embodiment of the adjustment device which is the subject of the present invention, illustrated by FIGS. 1 to 4, comprises a metal bracelet with links 1, partially shown, two
C'est précisément à cette autre extrémité 1b du
bracelet que se trouve un autre dispositif de réglage de la
longueur du bracelet, celui qui fait l'objet de la présente
invention.It is precisely at this
Un maillon 6 est monté pivotant autour de l'axe 5 de la
barrette fixée dans deux perforations 4 des parois latérales
2c1, 2c2, du capot 2c qui se font face. Ce maillon 6 constitue
le maillon de réglage de la longueur du bracelet. A cet
effet, ce maillon de réglage 6 (figures 2 à 4) comporte un
second axe d'articulation 7 auquel est articulée une extrémité
d'un deuxième maillon 8, dont l'autre extrémité est articulée
au reste de l'extrémité 1b du bracelet autour d'un
axe 9. Comme on le voit en particulier sur la figure 4, ce
maillon 8 présente une lame cintrée 8a qui est tangente à
une portion de section cylindrique 8b coaxiale à l'axe d'articulation
7 à une extrémité, tandis qu'à son autre extrémité,
cette lame cintrée 8a est repliée pour former, avec la
portion de section cylindrique 8b et la lame 8a, une paroi
8d, ménageant un logement 8c destiné à recevoir le maillon
de réglage 6, comme illustré par la figure 2. Cette paroi 8d
a un profil en forme de S formant ainsi un rétrécissement à
l'entrée du logement 8c, dont la dimension est calculée pour
être légèrement inférieure à la dimension correspondante de
la partie du maillon de réglage 6 qui doit s'engager dans le
logement 8c, comme on le voit en particulier sur la figure
3. Cette paroi 8d sert donc de moyen d'accrochage pour le
maillon de réglage 6 lorsque celui-ci est engagé élastiquement
dans ce logement 8c.A
On peut constater sur la figure 2, que dans cette position
du dispositif de réglage, la droite d dessinée en
traits mixtes joignant les axes d'articulation 7 et 9, entre
d'une part, les deux maillons 6 et 8 et, d'autre part, le
maillon 8 et le reste du bracelet, passe à une certaine
distance de l'axe 5 de pivotement du maillon de réglage 6
sur le capot 2c du fermoir, formant ainsi un bras de levier
autour de l'axe 5. Le côté de cet axe 5 où se situe ce bras
de levier est choisi pour créer un couple tendant à faire
tourner le maillon de réglage 6 dans le sens de la flèche
F1, lorsqu'une traction est exercée sur le bracelet dans le
sens de la flèche F2 (fig. 2). Ce couple tend à maintenir le
maillon de réglage 6 croché dans le logement 8c du maillon
8. Pour le décrocher, il suffit d'exercer sur l'axe 9 du
maillon 8 à l'extrémité de la partie 1b du bracelet (fig.
1), une traction dans le sens de la flèche F3 (fig. 2),
après quoi le maillon de réglage peut pivoter dans le sens
de la flèche F4 en exerçant sur le maillon 8 une traction
dans le sens de F2 (fig. 3). Ce pivotement du maillon de
réglage 6 est limité par une butée 6a qui entre en contact
avec la face interne du capot 2c du fermoir 2 (fig. 4).It can be seen in Figure 2, that in this position of the adjustment device, the straight line drawn in phantom joining the
Comme on le remarque sur cette figure 4 qui illustre le
dispositif de réglage dans la position la plus longue du
bracelet conférée par ce dispositif, la droite d dessinée en
traits mixtes, joignant les axes 7 et 9 du maillon 8, ne
passe pas non plus par l'axe 5 de pivotement du maillon de
réglage 6. Dans ce cas, le bras de levier autour de l'axe 5
tend à produire un couple dans le sens F5 lorsqu'une force
de sens F6 est exercée sur le maillon 8 (fig. 4), ramenant
le maillon de réglage 6 dans la position de la figure 2,
après avoir exercé une pression sur le maillon 8 dans le
sens F7 (fig. 3) pour le crocher dans le logement 8c. As can be seen in this FIG. 4 which illustrates the adjustment device in the longest position of the bracelet conferred by this device, the straight line drawn in dashed lines, joining the
Le dispositif de réglage selon l'invention permet de choisir entre deux longueurs de bracelet déterminées. Le passage d'une position à l'autre n'est obtenu que volontairement par une manipulation simple, ne demandant pas d'habileté particulière de l'utilisateur. Une fois dans une position, il n'y a pas de risque que la longueur change involontairement. La longueur réglée est maintenue aussi longtemps que l'utilisateur n'en a pas décidé autrement. Le fermoir peut être ouvert et refermé sans que le réglage ne soit modifié. On peut aussi remarquer que dans l'une ou l'autre des positions de réglage, la hauteur du fermoir reste pratiquement inchangée, de sorte que ce dispositif ne nuit pas à l'aspect esthétique.The adjustment device according to the invention makes it possible to choose between two determined bracelet lengths. The passage from one position to another is only obtained voluntarily by simple handling, not requiring of particular skill of the user. Once in a position, there is no risk of the length changing involuntarily. The length set is also maintained as long as the user has not decided otherwise. The clasp can be opened and closed without adjusting be changed. We can also notice that in one or the other of the adjustment positions, the height of the clasp remains practically unchanged, so that this device does not does not harm the aesthetic aspect.
Dans les quatre variantes illustrées par les figures 5
à 8, le fermoir n'a pas été représenté, étant donné qu'il
n'est pas modifié. Le maillon de réglage 6 est également
identique à celui des figures 1 à 4. Les modifications concernent
donc essentiellement le maillon 8 articulé autour de
l'axe 7 du maillon de réglage 6. La partie 1b du bracelet
proprement dite reliée à l'axe d'articulation 9 du maillon 8
peut être quelconque. On a représenté dans les exemples des
bracelets métalliques à maillons articulés. Rien n'empêche
cependant d'utiliser d'autres types de bracelets cuir ou
plastique par exemple. De même, il peut s'agir aussi bien
d'un bracelet de montre que de n'importe quel autre bracelet
muni d'un fermoir du type à lames déployantes ou d'un type
comparable, de façon générale de tout bracelet formant avec
son fermoir un lien sans fin.In the four variants illustrated by Figures 5
at 8, the clasp was not shown, since it
is not changed. The
Dans la variante illustrée par la figure 5, la paroi 8d
du logement 8'c du maillon 8 servant de moyen d'accrochage
du maillon de réglage 6 est constituée par une pièce
rapportée 8'd, soudée au maillon 8'. Cette variante permet
de réaliser cette pièce 8'd constituant les moyens d'accrochage
élastiques spécifiquement à cet effet pour obtenir la
force élastique désirée indépendamment du maillon 8'. C'est
ainsi que cet élément rapporté 8'd peut avoir une autre
épaisseur, voire être en un matériau différent de celui du
maillon 8'. Par exemple, dans le cas d'un bracelet or, il
peut être intéressant d'avoir un élément rapporté d'une
autre matière, par exemple de l'acier, en raison de ses
meilleures propriétés élastiques.In the variant illustrated in FIG. 5, the
La variante de la figure 6, qui illustre le dispositif
de réglage dans l'autre position de réglage, ne diffère de
celle de la figure 5 que par le fait que les lamelles 8"d
formant les moyens d'accrochage sont découpées dans le
maillon 8" lui-même et ne sont pas constituées par une pièce
rapportée.The variant of Figure 6, which illustrates the device
in the other setting position, does not differ from
that of FIG. 5 only by the fact that the
Dans la variante illustrée par les figures 7 et 8, le
maillon 8* est en deux parties articulées l'une à l'autre
autour d'un axe 10. L'élément d'accrochage du maillon de
réglage 6 est alors directement constitué par les deux parties
8*d de ce maillon 8* entourant l'axe 10 autour duquel
elles sont articulées. Dans ce cas, l'élasticité des moyens
d'accrochage 8*d est uniquement conférée par la partie cintrée
8*a du maillon 8*. Sur les figures 7 et 8, on a représenté
deux bracelets différents, toujours métalliques à

- An adjustment device according to claim 1, characterized by the fact that said locking means (8d,8'd,8''d,8*d) are elastic means.
- An adjustment device according to any one of the preceding claims, characterized by the fact that said locking means (8d,8'd,8"d,8*d) are solid with said second link (8,8',8'',8*) of said attachment, articulated on the one hand to one (7) of the transverse axes (5,7) of said adjustment link (6) and on the other hand to one end (1b) of the bracelet, and said adjustment link (6) has an abutment (6a) adapted to limit angular displacement thereof against a face of the arm (2c) of the clasp (2) to which it is articulated, in the position in which said adjustment link (6) defines the longer adjusted length.
- An adjustment device according to any one of the preceding claims, characterized by the fact that when said adjustment link (6) is in engagement with said locking means (8d,8'd,8''d,8*d), the pivoting axis (5) of this adjustment link (6) is situated on one side of a straight line passing through the two articulation axes (7,9) of said second link (8,8',8'',8*) selected such that a tractive force (F2) exerted in the direction of this straight line generates, about the pivoting axis (5) of said adjustment link, a couple tending to hold this link (6) in engagement with said locking means (8d,8'd,8"d,8*d).
- An adjustment device according to claim 3, characterized by the fact that when said abutment (6a) of said adjustment link (6) bears against said face of the clasp's arm (2c), the pivoting axis (5) of this adjustment link (6) is situated on one side of a straight line passing through the two articulation axes (7,9) of said second link (8,8',8'',8*) selected such that a pressure (F6) exerted in the direction of this straight line generates, about the pivoting axis (5) of said adjustment link (6), a couple tending to turn said adjustment link (6) from its position corresponding to the longer adjusted length to the other position corresponding to the shorter adjusted length of said attachment.
- An adjustment device according to claim 2, characterized by the fact that the elasticity of said locking means (8,8*d) is provided by a curved blade (8a,8*a) of said second link (8,8*), the locking means (8d,8*d) being arranged at one end of this curved blade (8a,8*a).
- An adjustment device according to any one of the preceding claims, characterized by the fact that the elastic locking means (8'd) are fitted on said second link (8').
- An adjustment device according to any one of the preceding claims, characterized by the fact that said second link (8,8',8",8*) has a recess (8c) for receiving said adjustment link (6) in the locking position of the adjustment link (6).
