  • the present invention relates to a reversible watch, and a method of turning a reversible watch case.
  • reversible watch is meant a watch the case of which has two faces and a turning mechanism allowing the user to display either side as desired.

  • Reversible watches are thus known for example comprising two mechanical movements for displaying, for example, two time zones on the two faces of the watch, or for displaying the time on one face and auxiliary functions, for example chronograph functions, phases moon, date, etc. on the other phase.

Watches comprising a single mechanical movement capable of displaying indications on two opposite faces are also known; such movements, complex and often produced in limited quantities, are also expensive. There are also known watches comprising two head-to-tail quartz movements, but which do not have the advantages or the prestige of mechanical movements. These watches require in particular one, or even two separate batteries. Different reversal mechanisms have been devised.
  • Watches are known, for example, in which the bracelet is turned over with the middle part, the inside face and the outside face of the strap and of the watch which can thus be inverted.
  • This solution requires bracelets and reversible bracelet clasps, the aesthetics of both sides of which is very careful.
  • Watches are also known in which the middle pivots around an axis 9 o'clock - 3 o'clock, that is to say an axis perpendicular to the bracelet.
  • the turning mechanism occupies the space around the middle part usually assigned to the time-setting crown and to the other control members, which implies severe aesthetic constraints for watch manufacturers and designers.
  • the middle part is however connected to the external frame by a single pivot allowing relative movement of the box according to two degrees of freedom.
  • a pivot must therefore be machined with very high precision, which increases the cost of the mechanism.
  • Turning the watch involves moving the middle part relative to the frame along a complex three-dimensional trajectory, difficult to grasp, and generally requiring the user to grasp the lens or glasses between the fingers, leaving finger marks.
  • the reliability of the turning mechanism is problematic, the pivot being able to seize or even break under the effect of impacts or even slight twists.
  • the middle part, and more particularly the projecting members of the middle part such as the control buttons, risk coming into contact with the external frame during pivoting, which risks scratching or marking them.
  • Patent CH177310 describes a reversible watch comprising a middle part provided with a pivot sliding in a slide of an external frame.
  • the middle part is turned by pivoting the case around the pivot to the vertical position, moving the pivot in the slide, then ending the pivoting of the middle.
  • the middle part is connected to the outer frame through a single pivot, which poses reliability problems and machining difficulties.
  • reversible watches including a turning mechanism allowing the middle to be pivoted around an axis 6 o'clock - 12 o'clock use a middle connected to an external frame by means of two pivots on the external faces of the middle guided in behind the scenes of the frame. Solutions of this type are described in particular in documents CH159982 and EP22255. In these watches, the reliability and robustness of the turning mechanism is improved thanks to the middle-frame connection at two points; moreover, the handling required for turning is more intuitive and does not require touching the glass. However, in these solutions, the turning axis of the middle part moves in a plane parallel to the watch, and therefore remains close to the bottom of the external frame.
  • the lateral faces of the middle part must therefore be adapted to allow the middle part to be turned over without these faces touching the bottom of the external frame.
  • This solution is therefore not suitable for watches comprising control members on two opposite lateral faces, in particular watches comprising both protruding control members on a first portion of the periphery of the middle between 12 o'clock and 6 o'clock , and projecting control members on a second portion of the periphery of the middle part between 6 am and 12 pm.
  • FR766809 describes in particular a reversible watch comprising a turning mechanism making it possible to pivot the middle around an axis from 6 o'clock to 12 o'clock.
  • the middle part is linked to two connecting rods which are parallel to each other and articulated with respect to the watch frame.
  • the watch is turned over by simultaneously lifting the two links then turning the middle part relative to an axis linked to the two links.

A turning-over mechanism ( 20, 21, 22, 23 ) allows the case ( 1 ) to be turned over around a turning-over axis ( 201 - 211; 221 - 231 ) parallel to the 6 o'clock-12 o'clock axis so as to display at the wearer's preference either the first face or the second face. The turning-over mechanism comprising a pivoting arm ( 20, 21; 22, 23 ) on each side of the case that allows the turning-over axis to be moved back. The case ( 1 ) is connected with the arms ( 20, 21; 22, 23 ) to be able to pivot around the turning-over axis ( 201 - 211; 221 - 231 ). The length of the arms is sufficient for turning over the case without the winding button or other buttons coming into contact with other parts ( 17 ) of the watch.

Description

Montre réversible Reversible watch
La présente invention concerne une montre réversible, et un procédé de retournement d'une boîte de montre réversible.The present invention relates to a reversible watch, and a method of turning a reversible watch case.
Par montre réversible, on entend une montre dont le boîtier comporte deux faces et un mécanisme de retournement permettant à l'utilisateur d'afficher au choix l'une ou l'autre face. Au moins une des faces comporte un cadran avec des indications horaires ; la face opposée porte soit un autre cadran avec d'autres indications horaires, par exemple un autre fuseau horaire ou des fonctions complémentaires, soit un couvercle protecteur fréquemment décoré.By reversible watch is meant a watch the case of which has two faces and a turning mechanism allowing the user to display either side as desired. At least one of the faces has a dial with time indications; the opposite face carries either another dial with other time indications, for example another time zone or additional functions, or a frequently decorated protective cover.
On connaît ainsi par exemple des montres réversibles comportant deux mouvements mécaniques pour afficher par exemple deux fuseaux horaires sur les deux faces de la montre, ou pour afficher l'heure sur une face et des fonctions auxiliaires, par exemple des fonctions de chronographe, de phases de la lune, de date, etc. sur l'autre phase. Intégrer deux mouvements mécaniques dans une seule boîte est cependant coûteux et nécessite une épaisseur importante. Des montres comportant un seul mouvement mécanique capable d'afficher des indications sur deux faces opposées sont aussi connues; de tels mouvements, complexes et produits souvent en quantités restreintes, sont également onéreux. On connaît aussi des montres comprenant deux mouvements à quartz tête-bêche, mais qui n'ont pas les avantages ni le prestige des mouvements mécaniques. Ces montres nécessitent en particulier une, voire même deux batteries distinctes. Différents mécanismes de retournement ont été imaginés. On connaît par exemple des montres dans lesquels le bracelet est retourné avec la carrure, la face intérieure et la face extérieure du bracelet et de la montre pouvant ainsi être interverties. Cette solution nécessite cependant des bracelets et des fermoirs de bracelet réversibles dont l'esthétique des deux faces est très soignée. Reversible watches are thus known for example comprising two mechanical movements for displaying, for example, two time zones on the two faces of the watch, or for displaying the time on one face and auxiliary functions, for example chronograph functions, phases moon, date, etc. on the other phase. Integrating two mechanical movements in a single box is however expensive and requires significant thickness. Watches comprising a single mechanical movement capable of displaying indications on two opposite faces are also known; such movements, complex and often produced in limited quantities, are also expensive. There are also known watches comprising two head-to-tail quartz movements, but which do not have the advantages or the prestige of mechanical movements. These watches require in particular one, or even two separate batteries. Different reversal mechanisms have been devised. Watches are known, for example, in which the bracelet is turned over with the middle part, the inside face and the outside face of the strap and of the watch which can thus be inverted. This solution, however, requires bracelets and reversible bracelet clasps, the aesthetics of both sides of which is very careful.
On connaît également des montres dans lesquels la carrure pivote autour d'un axe 9 heures - 3 heures, c'est-à-dire un axe perpendiculaire au bracelet. Le mécanisme de retournement occupe dans ce cas l'espace autour de la carrure habituellement dévolu à la couronne de mise à l'heure et aux autres organes de commande, ce qui implique des contraintes esthétiques sévères pour les fabricants et designers de montre.Watches are also known in which the middle pivots around an axis 9 o'clock - 3 o'clock, that is to say an axis perpendicular to the bracelet. In this case, the turning mechanism occupies the space around the middle part usually assigned to the time-setting crown and to the other control members, which implies severe aesthetic constraints for watch manufacturers and designers.
Les montres réversibles les plus répandues utilisent donc un mécanisme de retournement permettant de faire pivoter la carrure autour d'un axe 6 heures - 12 heures dans le plan du bracelet. La demande de brevet FR2716353 décrit par exemple une montre dans laquelle chaque brin du bracelet est relié à la carrure au moyen d'un pivot permettant de retourner la montre autour de l'axe 6 heures - 12 heures. Il est cependant nécessaire de retirer la montre du poignet pour faire pivoter la carrure. Des solutions similaires permettant le pivotement au niveau de l'attache du bracelet sont décrites notamment dans les documents GB2213612, GB2241868, EP346660, CH659167, FR2583897, CH172421, CH138929, US4470708 et CH674291.The most common reversible watches therefore use a turning mechanism allowing the middle to be pivoted around an axis 6 o'clock - 12 o'clock in the plane of the bracelet. Patent application FR2716353 describes for example a watch in which each strand of the bracelet is connected to the middle part by means of a pivot making it possible to turn the watch around the axis from 6 o'clock to 12 o'clock. It is however necessary to remove the watch from the wrist to rotate the middle. Similar solutions allowing pivoting at the strap attachment are described in particular in documents GB2213612, GB2241868, EP346660, CH659167, FR2583897, CH172421, CH138929, US4470708 and CH674291.
Différentes solutions connues proposent en outre d'insérer la carrure dans un cadre externe lié au bracelet, et de faire pivoter la carrure par rapport au cadre autour d'un pivot, selon un axe 6 heures - 12 heures. Des exemples d'une telle montre sont décrits dans les documents CH 159446, CH 176988 et EP562522 notamment.Various known solutions also propose to insert the middle part in an external frame linked to the bracelet, and to rotate the middle part relative to the frame around a pivot, along an axis from 6 o'clock to 12 o'clock. Examples of such a watch are described in documents CH 159446, CH 176988 and EP562522 in particular.
Dans ces solutions, la carrure est toutefois reliée au cadre extérieur par un seul pivot permettant un déplacement relatif de la boîte selon deux degrés de liberté. Un tel pivot doit donc être usiné avec une très grande précision, ce qui renchérit le mécanisme. Le retournement de la montre implique de déplacer la carrure par rapport au cadre selon une trajectoire tri-dimensionnelle complexe, difficile à appréhender, et nécessitant généralement que l'utilisateur saisisse la ou les glaces entre les doigts, laissant des marques de doigt. Par ailleurs, la fiabilité du mécanisme de retournement est problématique, le pivot pouvant se gripper ou même se casser sous l'effet de chocs ou de torsions même peu importantes. Enfin, la carrure, et plus particulièrement les organes saillants de la carrure comme les boutons de commande, risquent d'entre en contact avec le cadre externe lors du pivotement, ce qui risque de les rayer ou de les marquer.In these solutions, the middle part is however connected to the external frame by a single pivot allowing relative movement of the box according to two degrees of freedom. Such a pivot must therefore be machined with very high precision, which increases the cost of the mechanism. Turning the watch involves moving the middle part relative to the frame along a complex three-dimensional trajectory, difficult to grasp, and generally requiring the user to grasp the lens or glasses between the fingers, leaving finger marks. Furthermore, the reliability of the turning mechanism is problematic, the pivot being able to seize or even break under the effect of impacts or even slight twists. Finally, the middle part, and more particularly the projecting members of the middle part such as the control buttons, risk coming into contact with the external frame during pivoting, which risks scratching or marking them.
Le brevet CH177310 décrit une montre réversible comprenant une carrure munie d'un pivot coulissant dans une coulisse d'un cadre extérieur. Le retournement de la carrure est effectué en pivotant la boîte autour du pivot jusqu'à la position verticale, en déplaçant le pivot dans la coulisse, puis en terminant le pivotement de la carrure. Dans ce cas également, la carrure est reliée au cadre extérieur au travers d'un seul pivot, ce qui pose des problèmes de fiabilité et de difficultés d'usinage.Patent CH177310 describes a reversible watch comprising a middle part provided with a pivot sliding in a slide of an external frame. The middle part is turned by pivoting the case around the pivot to the vertical position, moving the pivot in the slide, then ending the pivoting of the middle. In this case also, the middle part is connected to the outer frame through a single pivot, which poses reliability problems and machining difficulties.
D'autres montres réversibles comprenant un mécanisme de retournement permettant de faire pivoter la carrure autour d'un axe 6 heures - 12 heures utilisent une carrure reliée à un cadre externe à l'aide de deux pivots sur les faces externes de la carrure guidés dans des coulisses du cadre. Des solutions de ce type sont décrites notamment dans les documents CH159982 et EP22255. Dans ces montres, la fiabilité et la robustesse du mécanisme de retournement est améliorée grâce à la liaison carrure-cadre en deux points; par ailleurs, la manipulation nécessaire pour le retournement est plus intuitive et ne nécessite pas de toucher la glace. Toutefois, dans ces solutions, l'axe de retournement de la carrure se déplace dans un plan parallèle à la montre, et reste donc proche du fond du cadre externe. Les faces latérales de la carrure doivent donc être adaptées pour permettre le retournement de la carrure sans que ces faces ne touchent le fond du cadre externe. En particulier, il est impossible de disposer des boutons de commande ou des couronnes de remontoir trop saillants sur la face latérale de la carrure proche de l'axe de retournement; ces organes risqueraient en effet d'entrer en collision avec le fond du cadre lors du retournement. Cette solution n'est donc pas adaptée à des montres comportant des organes de commande sur deux faces latérales opposées, notamment des montres comportant à la fois des organes de commande saillants sur une première portion de la périphérie de la carrure entre 12 heures et 6 heures, et des organes de commande saillants sur une deuxième portion de la périphérie de la carrure entre 6 heures et 12 heures. Other reversible watches including a turning mechanism allowing the middle to be pivoted around an axis 6 o'clock - 12 o'clock use a middle connected to an external frame by means of two pivots on the external faces of the middle guided in behind the scenes of the frame. Solutions of this type are described in particular in documents CH159982 and EP22255. In these watches, the reliability and robustness of the turning mechanism is improved thanks to the middle-frame connection at two points; moreover, the handling required for turning is more intuitive and does not require touching the glass. However, in these solutions, the turning axis of the middle part moves in a plane parallel to the watch, and therefore remains close to the bottom of the external frame. The lateral faces of the middle part must therefore be adapted to allow the middle part to be turned over without these faces touching the bottom of the external frame. In particular, it is impossible to have control buttons or winding crowns too protruding on the side face of the middle close to the turning axis; these bodies could indeed collide with the bottom of the frame during the overturning. This solution is therefore not suitable for watches comprising control members on two opposite lateral faces, in particular watches comprising both protruding control members on a first portion of the periphery of the middle between 12 o'clock and 6 o'clock , and projecting control members on a second portion of the periphery of the middle part between 6 am and 12 pm.
FR766809 décrit notamment une montre réversible comprenant un mécanisme de retournement permettant de faire pivoter la carrure autour d'un axe 6 heures - 12 heures. La carrure est liée à deux biellettes parallèles entre elles et articulées par rapport au cadre de la montre. La montre est retournée en soulevant simultanément les deux biellettes puis en retournant la carrure par rapport à un axe lié aux deux biellettes. Il est nécessaire de retourner la carrure en orientant la face latérale de la montre dépourvue de remontoir vers le cadre ; la carrure ne pourrait pas être retournée si elle présentait des organes de commande sur les deux faces latérales, par exemple à la fois à 3heures et à 9 heures.FR766809 describes in particular a reversible watch comprising a turning mechanism making it possible to pivot the middle around an axis from 6 o'clock to 12 o'clock. The middle part is linked to two connecting rods which are parallel to each other and articulated with respect to the watch frame. The watch is turned over by simultaneously lifting the two links then turning the middle part relative to an axis linked to the two links. It is necessary to turn the middle part by orienting the side face of the watch without winding towards the frame; the middle could not be turned over if it had control elements on the two side faces, for example both at 3 o'clock and at 9 o'clock.
Par ailleurs, la carrure peut pivoter autour de l'axe de l'axe de retournement même lorsque les biellettes ne sont que partiellement relevées. La carrure et le remontoir risquent à cette occasion d'entrer en contact avec le cadre 21, ce qui pourrait les rayer ou même les endommager.Furthermore, the middle part can pivot around the axis of the turning axis even when the links are only partially raised. The middle and the winding may on this occasion come into contact with the frame 21, which could scratch or even damage them.
Enfin, dans la plupart des solutions décrites, la plus grande partie des coulisses est apparente au moins lors de certaines étapes du retournement, ce qui est peu esthétique et surtout risque de les exposer à des poussières ou à des débris de peau qui peuvent dans certain cas les bloquer et empêcher un retournement de la montre. Enfin, les coulisses sont des pièces d'usure qui ne peuvent pas, ou que difficilement, être remplacées lorsque le guidage de la carrure devient trop imprécis.Finally, in most of the solutions described, most of the slides are visible at least during certain stages of the turning, which is unattractive and above all risks exposing them to dust or to skin debris which may in certain If so, block them and prevent the watch from turning over. Finally, the slides are wearing parts which cannot, or only with difficulty, be replaced when the guide of the middle becomes too imprecise.
Un but de la présente invention est donc de proposer une nouvelle montre réversible pourvue d'un mécanisme de retournement qui évite les défauts des mécanismes de retournement de l'art antérieur.An object of the present invention is therefore to propose a new reversible watch provided with a turning mechanism which avoids the defects of the turning mechanisms of the prior art.
En particulier, un but de la présente invention est de proposer un mécanisme de retournement suffisamment rigide et fiable, et permettant de retourner des carrures pourvues d'organes de commande saillants sur une ou plusieurs faces de la carrure, sans que ces organes de commande ou d'autres parties de la carrure ne puissent être abîmés au cours du retournement. In particular, an object of the present invention is to propose a sufficiently rigid and reliable turning mechanism, making it possible to turn the middle parts provided with protruding control members on one or more faces of the middle, without these control members or other parts of the middle cannot be damaged during the turning.
Un autre but de la présente invention est de proposer un mécanisme de retournement dans lequel le nombre de pièces mobiles est diminué, afin de baisser le coût de fabrication, de réduire l'encombrement et d'améliorer la fiabilité.Another object of the present invention is to provide a turning mechanism in which the number of moving parts is reduced, in order to lower the manufacturing cost, reduce the size and improve reliability.
Un autre but de la présente invention est de proposer une montre réversible pouvant offrir un plus grand nombre de fonctionnalités et d'affichages sur les deux faces de la montre que les montres réversibles de l'art antérieur.Another object of the present invention is to provide a reversible watch that can offer a greater number of functionalities and displays on both sides of the watch than the reversible watches of the prior art.
Selon l'invention, ces objectifs sont atteints notamment au moyen d'une montre réversible et d'un procédé comportant les caractéristiques des revendications indépendantes de type correspondant, des variantes préférentielles étant indiquées dans les revendications dépendantes.According to the invention, these objectives are achieved in particular by means of a reversible watch and a method comprising the characteristics of the independent claims of the corresponding type, preferential variants being indicated in the dependent claims.
En particulier, ces objectifs sont atteints au moyen d'une montre réversible comprenant une carrure munie d'une première face pour afficher des premières indications horaires et d'une deuxième face opposée à ladite première face, au moins un organe de commande du ou des mouvements de la montre saillants sur une première portion de la périphérie de la carrure entre 12 heures et 6 heures, et au moins un autre organe de commande du ou des mouvements de la montre saillants sur une première portion de la périphérie de la carrure entre 6 heures et 12 heures, un mécanisme de retournement pour retourner ladite carrure autour d'un axe de retournement, ledit axe de retournement étant parallèle à l'axe 6 heures-12 heures lors du retournement, de façon à afficher, au choix du porteur, soit ladite première face, soit ladite deuxième face. Selon l'invention, la carrure est liée à des bras pivotants de manière à pouvoir pivoter autour d'un axe de retournement lié au cadre externe. Les bras permettent de déplacer l'axe de retournement au cours du retournement; leur longueur et leur disposition sont adaptées pour pouvoir retourner la carrure sans que les organes de commande n'entrent en contact avec d'autres parties de la montre lors du retournement. In particular, these objectives are achieved by means of a reversible watch comprising a middle part provided with a first face for displaying first time indications and with a second face opposite to said first face, at least one control member for the movements of the watch projecting over a first portion of the periphery of the middle between 12 o'clock and 6 o'clock, and at least one other member controlling the movement or movements of the watch projecting over a first portion of the periphery of the middle between 6 hours and 12 hours, a turning mechanism for turning said middle around a turning axis, said turning axis being parallel to the axis from 6 to 12 o'clock during turning, so as to display, at the wearer's choice, either said first face or said second face. According to the invention, the middle part is linked to pivoting arms so as to be able to pivot around a turning axis linked to the external frame. The arms make it possible to move the turning axis during the turning; their length and arrangement are adapted to be able to turn the middle without the control members coming into contact with other parts of the watch during turning.
Ces objectifs sont aussi atteints à l'aide d'une montre réversible comprenant une carrure munie d'une première face pour afficher des premières indications horaires et d'une deuxième face opposée à ladite première face, au moins un organe de commande du ou des mouvements de la montre. Un mécanisme de retournement permet de retourner la carrure autour d'un axe de retournement, ledit axe de retournement étant parallèle à l'axe 6 heures-12 heures lors du retournement, de façon à afficher, au choix du porteur, soit ladite première face, soit ladite deuxième face. Selon l'invention, le mécanisme de retournement comporte un bras pivotant de chaque côté de ladite carrure. Les bras permettent de déplacer l'axe de retournement. La carrure est liée aux bras de façon à permettre le retournement de la carrure autour de l'axe de retournement uniquement lorsque les bras sont inclinés d'un angle prédéterminé par rapport à la position initiale. La longueur des bras est suffisante et leurs agencements adaptés pour permettre de retourner la carrure sans que les organes de commande, ou d'autres parties de la carrure n'entrent en collision avec d'autres parties de la montre lors du retournement.These objectives are also achieved using a reversible watch comprising a middle part provided with a first face to display first time indications and a second face opposite to said first face, at least one control member of the watch movements. A turning mechanism makes it possible to turn the middle around a turning axis, said turning axis being parallel to the axis from 6 am to 12 pm during the turning, so as to display, at the option of the wearer, that is said first face. , or said second face. According to the invention, the turning mechanism comprises a pivoting arm on each side of said middle. The arms move the turning axis. The middle part is linked to the arms so as to allow the middle part to be turned around the turning axis only when the arms are inclined at a predetermined angle relative to the initial position. The length of the arms is sufficient and their arrangements adapted to allow the middle part to be turned over without the control members or other parts of the middle part colliding with other parts of the watch during the turning over.
Cette solution a l'avantage de déplacer l'axe de retournement de la carrure au cours du retournement. Il est ainsi possible de l'amener en une position plus favorable, permettant de retourner des boîtes de montre volumineuses ou pourvues d'organes de commande saillants sur une ou plusieurs faces, sans que la carrure ou les organes de commande ne touchent d'autres parties de la montre au cours du retournement.This solution has the advantage of displacing the turning axis of the middle part during the turning. It is thus possible to bring it into a more favorable position, making it possible to return large watch cases or provided with projecting control members on one or more sides, without the middle or the control members touching other parts of the watch during turning.
La présente invention sera mieux comprise à l'aide de la description d'exemples de mise en œuvre illustrés par les figures annexées qui montrent:The present invention will be better understood using the description of examples of implementation illustrated by the appended figures which show:

Figure 19 a sectional view of a watch case according to the invention.
La figure 1 illustre une vue de dessus d'une montre réversible selon un premier mode de réalisation de l'invention. Dans cette position, également illustrée sur la figure 2, la face 10 de la montre comportant un affichage à aiguilles 100 est visible sur le dessus de la montre, l'autre face 11 avec un affichage alphanumérique 110 visible notamment sur la figure 10 étant tournée en direction du poignet du porteur. Pour la simplification des figures, les organes d'affichage (aiguilles ou affichage à cristaux liquides) et le bracelet ne sont représentés que dans les positions de repos illustrées sur les figures 1 et 10.Figure 1 illustrates a top view of a reversible watch according to a first embodiment of the invention. In this position, also illustrated in FIG. 2, the face 10 of the watch comprising a needle display 100 is visible on the top of the watch, the other face 11 with an alphanumeric display 110 visible in particular in FIG. 10 being turned towards the wearer's wrist. For the simplification of the figures, the display members (hands or liquid crystal display) and the bracelet are only shown in the rest positions illustrated in FIGS. 1 and 10.
La montre comporte une carrure 1 contenant les mouvements de la montre et montée dans un cadre 17 au moyen d'un mécanisme de retournement 2 décrit plus loin. Un bracelet 13 est fixé au cadre 17 par l'intermédiaire de cornes 171. Le mouvement contrôlant la position des The watch has a middle part 1 containing the movements of the watch and mounted in a frame 17 by means of a turning mechanism 2 described below. A bracelet 13 is fixed to the frame 17 by means of horns 171. The movement controlling the position of the
aiguilles peut être remonté et/ou mis à l'heure au moyen d'une couronne de remontoir 16 sur une des faces latérales de la carrure 1. D'autres organes de commande, ici des boutons-poussoirs 14, 15, permettent de commander d'autres fonctions de la montre, notamment des fonctions affichées sur l'autre face de la montre, comme décrit plus loin. Les organes de commande 14, 15, 16 sont répartis sur deux faces latérales opposées de la carrure et occupent donc aussi bien la portion de la périphérie de la carrure entre 12 heures et 6 heures que la portion comprise entre 6 heures et 12 heures. Les organes de commande sont saillants, ce qui permet une manipulation plus commode, sur les deux faces de la carrure 1.hands can be wound and / or set by time by means of a winding crown 16 on one of the lateral faces of the middle part. Other control members, here push-buttons 14, 15, make it possible to control other functions of the watch, in particular functions displayed on the other face of the watch, as described below. The control members 14, 15, 16 are distributed on two opposite lateral faces of the middle part and therefore occupy both the portion of the periphery of the middle part between 12 o'clock and 6 o'clock as well as the portion between 6 o'clock and 12 o'clock. The control members are protruding, which allows more convenient handling, on both sides of the middle part 1.
Le mécanisme de retournement de ce premier mode de réalisation comporte un bras pivotant 20 et 21 fermant en position repliée deux faces frontales opposées du cadre 17. Dans la variante illustrée, la carrure est rectangulaire ou carrée et la longueur des bras est sensiblement égale à la largeur de la carrure. Les bras peuvent se déplier de la façon illustrée sur les figures 3 à 10 en pivotant dans deux plans verticaux (c'est-à- dire perpendiculaires au fond 170 du cadre 17) autour d'axes de rotation 200 respectivement 210 lié au cadre 17. L'angle de rotation atteint par le bras 20 par rapport à sa position initiale est indiqué sur les figures par la référence α. Les deux axes de rotation 200 et 210 des deux bras 20 et 21 sont parallèles entre eux et liés à des positions diamétralement opposées du cadre 17.The turning mechanism of this first embodiment comprises a pivoting arm 20 and 21 closing in the folded position two opposite front faces of the frame 17. In the illustrated variant, the middle is rectangular or square and the length of the arms is substantially equal to the width of the middle. The arms can be unfolded in the manner illustrated in FIGS. 3 to 10 by pivoting in two vertical planes (that is to say perpendicular to the bottom 170 of the frame 17) around axes of rotation 200 respectively 210 linked to the frame 17 The angle of rotation reached by the arm 20 relative to its initial position is indicated in the figures by the reference α. The two axes of rotation 200 and 210 of the two arms 20 and 21 are mutually parallel and linked to diametrically opposite positions of the frame 17.
La carrure 1 est liée aux deux bras pivotants 20 et 21 par deux pivots 201, 211 définissant un axe de retournement. Elle peut ainsi être retournée autour de l'axe de retournement 201-211 lorsque les bras sont dépliés. En position de repos, pour afficher l'une des faces 10 ou 11, les bras 20, 21 sont maintenus par des billes montées sur ressort (non représentées) engagées dans des trous 28 sur les faces internes des cornes 171. Une légère force verticale sur la carrure 1 est suffisante pour dégager les billes et libérer les bras afin de les déplier pour retourner la carrure.The middle part 1 is linked to the two pivoting arms 20 and 21 by two pivots 201, 211 defining an axis of reversal. It can thus be turned around the turning axis 201-211 when the arms are unfolded. In the rest position, to display one of the faces 10 or 11, the arms 20, 21 are held by balls mounted on a spring (not shown) engaged in holes 28 on the internal faces of the horns 171. A slight vertical force on the middle 1 is sufficient to release the balls and release the arms to unfold them to turn the middle.
Comme on le voit sur les figures 3 à 10, les bras 20 et 21 permettent de soulever et d'aligner les pivots 201-211, et donc l'axe de As seen in Figures 3 to 10, the arms 20 and 21 are used to lift and align the pivots 201-211, and therefore the axis of
retournement, de la carrure 1 au-dessus du plan initial contenant la face supérieure de la carrure en position de repos. Dans ce mode de réalisation, l'axe de retournement 201-211 se déplace donc en pivotant les bras 20, 21 autour de l'axe de rotation 200-210 au cours du retournement. La 5 manipulation nécessaire pour soulever la carrure 1 est donc intuitive et ne nécessite pas de mouvements complexes. Durant toutes les phases du retournement, les bras 20-21 relient solidairement la carrure 1 au cadre 17.overturning, the middle part 1 above the initial plane containing the upper face of the middle part in the rest position. In this embodiment, the turning axis 201-211 therefore moves by pivoting the arms 20, 21 around the axis of rotation 200-210 during the turning. The manipulation necessary to lift the middle part 1 is therefore intuitive and does not require complex movements. During all the phases of the turning, the arms 20-21 connect the middle part 1 to the frame 17.
La longueur des deux bras 20, 21, et la distance entre les axes de rotation des bras 200-210 et l'axe de retournement de la carrure 201-211,The length of the two arms 20, 21, and the distance between the axes of rotation of the arms 200-210 and the turning axis of the middle part 201-211,
10 est suffisante pour permettre le retournement de la carrure sans que les organes de commande 14, 15, 16, ou d'autres parties de la carrure 1, n'entrent en contact avec le cadre 17 ou avec d'autres parties de la montre. Il est ainsi possible de changer la face affichée 10 ou 11 lorsque les bras sont dépliés sans risquer de marquer, de rayer ou même d'abîmer les10 is sufficient to allow the middle part to be turned over without the control members 14, 15, 16 or other parts of the middle part 1 coming into contact with the frame 17 or with other parts of the watch . It is thus possible to change the displayed face 10 or 11 when the arms are unfolded without risking marking, scratching or even damaging the
15 organes de commande 14, 15, 16 ou la carrure 1. Comme illustré notamment sur les figures 3 à 9, les deux bras 20, 21 restent parallèles avec des orientations opposées au cours du retournement.15 control members 14, 15, 16 or the middle part 1. As illustrated in particular in FIGS. 3 to 9, the two arms 20, 21 remain parallel with opposite orientations during the inversion.
Comme on le voit en particulier sur les figures 11c et 11 d qui représentent une vue de la face interne du bras 21, respectivement uneAs can be seen in particular in FIGS. 11c and 11d which represent a view of the internal face of the arm 21, respectively a
20 coupe de ce bras selon l'axe Xld, les deux bras 20, 21 comprennent chacun une première coulisse 202 (non représentée) respectivement 212 en forme de A, ainsi qu'un pivot 201 (non représenté) respectivement 211. Les pivots 201 respectivement 211 se déplacent dans des deuxièmes coulisses 250 respectivement 260 en forme de S usinées dans des porte-coulisses 2520 section of this arm along the axis Xld, the two arms 20, 21 each comprise a first slide 202 (not shown) respectively 212 in the form of A, as well as a pivot 201 (not shown) respectively 211. The pivots 201 respectively 211 move in second slides 250 respectively 260 S-shaped machined in slide holders 25
25 respectivement 26 liés aux deux faces frontales de la carrure 1. Inversement, les porte-coulisses 25 respectivement 26 portent chacun deux pivots de guidage 251 (non représentés) respectivement 261 se déplaçant dans les premières coulisses 202, 212.25 respectively 26 linked to the two end faces of the middle part 1. Conversely, the slide carriers 25 respectively 26 each carry two guide pivots 251 (not shown) respectively 261 moving in the first slides 202, 212.
La carrure 1 étant liée au cadre externe 17 par les deux bras 20, 30 21 dirigés selon des directions opposées, elle est déplacée verticalement bloquée en position horizontale et soulève les deux bras 20, 21. En soulevant la carrure 1, le pivot 211 se déplace dans la coulisse 260 en forme The middle part 1 being linked to the external frame 17 by the two arms 20, 30 21 directed in opposite directions, it is moved vertically locked in a horizontal position and lifts the two arms 20, 21. By lifting the middle part 1, the pivot 211 moves in the slide 260 shaped
de S liée à la carrure et simultanément les deux pivots 261 se déplacent dans la coulisse 212 en forme de A. De la même façon, les pivots 251 se déplacent dans la coulisse 202 du bras 20 tandis que le pivot 201 se déplace dans la coulisse 250 liée au porte-coulisse 25.of S linked to the middle part and simultaneously the two pivots 261 move in the slide 212 in the form of A. Similarly, the pivots 251 move in the slide 202 of the arm 20 while the pivot 201 moves in the slide 250 linked to the slide holder 25.
5 La forme particulière en A des coulisses de guidage 202, 212 ainsi que le manque d'alignement des deux pivots 201 et 211 permet de maintenir la carrure 1 horizontale, c'est-à-dire parallèle à sa position de repos initiale, dans toutes les positions à l'exception du point de retournement illustré sur les figures 13 et 14. En effet, les deux pivots 2015 The particular shape in A of the guide slides 202, 212 as well as the lack of alignment of the two pivots 201 and 211 makes it possible to keep the middle part 1 horizontal, that is to say parallel to its initial rest position, in all positions except the turning point illustrated in Figures 13 and 14. Indeed, the two pivots 201
10 respectivement 211 sont incapables de pivoter simultanément, sauf • lorsqu'ils sont alignés dans l'axe de retournement, positionnés à 6 heures et à 12 heures. Dans cette position particulière, les deux paires de pivots de guidage 251 et 261 se trouvent dans la portion circulaire de la coulisse 202 respectivement 212. Le porte-coulisse 26 peut alors pivoter autour du pivot10 respectively 211 are unable to rotate simultaneously, except when • aligned in the turning axis, positioned at 6 o'clock and 12 o'clock. In this particular position, the two pairs of guide pivots 251 and 261 are located in the circular portion of the slide 202 respectively 212. The slide holder 26 can then pivot around the pivot
15 211, les deux pivots de guidage 261 étant également libres de tourner dans la portion circulaire de la première coulisse 212. Le porte coulisse 25 effectue un même mouvement de retournement autour du pivot 201.15 211, the two guide pivots 261 also being free to rotate in the circular portion of the first slide 212. The slide holder 25 performs the same turning movement around the pivot 201.
La carrure 1 peut ainsi, uniquement dans cette position particulière, tourner librement autour de l'axe de retournement horizontal 20 201, 211. Dans toutes les autres positions des bras 20, 21, le retournement est bloqué par le non-alignement des pivots 201, 211et par le guidage des paires de pivots 251, 261 dans leurs coulisses respectives. Il n'y a donc pas de frottement possible entre les faces frontales de la carrure 1 et la face interne des bras 20, 21.The middle part 1 can thus, only in this particular position, rotate freely around the horizontal turning axis 20 201, 211. In all the other positions of the arms 20, 21, the turning is blocked by the non-alignment of the pivots 201 , 211 and by guiding the pairs of pivots 251, 261 in their respective slides. There is therefore no possible friction between the front faces of the middle part 1 and the internal face of the arms 20, 21.
25 Dans l'exemple de réalisation illustré, le point de retournement est atteint lorsque l'angle α d'inclinaison des bras 20, 21 vaut approximativement 50°, cette valeur étant choisie en fonction de la longueur des bras et de la largeur totale de la carrure pour assurer un retournement sans collision dans la position illustrée sur les figures 4 à 8 et 13 à 14. On assureIn the illustrated embodiment, the turning point is reached when the angle of inclination of the arms 20, 21 is approximately 50 °, this value being chosen as a function of the length of the arms and the total width of the middle part to ensure a flipping without collision in the position illustrated in FIGS. 4 to 8 and 13 to 14. It is ensured
30 ainsi qu'aucun point de la carrure 1 ou des organes de commande 14, 15, 16 n'entre en contact avec le cadre 17 lorsque les bras 20, 21 sont dépliés ou à nouveau repliés. 30 and that no point of the middle part 1 or of the control members 14, 15, 16 comes into contact with the frame 17 when the arms 20, 21 are unfolded or folded again.
Les deux pivots 201 et 211 définissent l'axe de retournement autour duquel la carrure 1 peut être retournée. Comme ces pivots se déplacent dans les deuxièmes coulisses 250, 260 en forme de S, l'axe de retournement, défini par la droite reliant les deux pivots 201, 211, traverse la carrure 1 par le centre selon des directions différentes lorsque les bras 20, 21 sont dépliés.The two pivots 201 and 211 define the turning axis around which the middle part 1 can be turned. As these pivots move in the second slides 250, 260 in the form of an S, the turning axis, defined by the right connecting the two pivots 201, 211, crosses the middle part 1 through the center in different directions when the arms 20 , 21 are unfolded.
La forme non rectiligne en S des deuxièmes coulisses 250, 260 permet de contrôler les forces de frottement exercées contre les pivots 201, 211. En particulier, cette forme permet de varier la force de réaction exercée par frottement contre les coulisses lors du dépliement et du repliement des bras 20, 21, de façon à obtenir un effet de déploiement puis de repli élastique plus intuitif. Le mécanisme de retournement pourrait aussi fonctionner, de manière moins confortable, avec des deuxièmes coulisses 250, 260 rectilignes.The non-rectilinear S shape of the second slides 250, 260 makes it possible to control the friction forces exerted against the pivots 201, 211. In particular, this shape makes it possible to vary the reaction force exerted by friction against the slides during the unfolding and the folding of the arms 20, 21, so as to obtain a deployment effect and then more intuitive elastic folding. The turning mechanism could also function, in a less comfortable way, with second slides 250, 260 rectilinear.
Dans une variante non illustrée, la position des coulisses et des pivots sur la carrure et les bras peut être intervertie. Par ailleurs, les "jambes" des coulisses 202, 212 en forme de A pourraient être élargies vers l'intérieur, de manière à assurer un contact en seul point des pivots 251, 261 et à réduire ainsi le frottement.In a variant not illustrated, the position of the slides and of the pivots on the middle part and the arms can be reversed. Furthermore, the "legs" of the slides 202, 212 in the form of A could be widened inwards, so as to ensure a single point of contact with the pivots 251, 261 and thus reduce friction.
Pour retourner la carrure et afficher l'autre face de la montre, le porteur de la montre lève donc la carrure 1 pour dégager les billes à ressort des trous 28, puis fait pivoter les bras 20-21 de 50° (dans cet exemple) jusqu'à la position de retournement illustrée sur les figures 4 à 8 et 13 à 14. Dans cette position, la carrure 1 peut pivoter librement autour de l'axe de retournement 201-211, en étant guidée par les pivots de guidage 251, 261, entre les deux positions horizontales opposées illustrées sur les figures 4 et 7. Le porteur de la montre repousse ensuite la carrure 1 pour replier les bras 20 et 21 et atteindre la deuxième position de repos illustrée sur la figure 10, avec la deuxième face 11 visible. La carrure 1 est maintenue dans cette position par les billes sur ressort non représentées engagées dans d'autres trous 28 sur les faces internes des cornes 171. To turn the middle part and display the other side of the watch, the wearer of the watch therefore lifts the middle part 1 to release the spring balls from the holes 28, then rotates the arms 20-21 by 50 ° (in this example) up to the turning position illustrated in FIGS. 4 to 8 and 13 to 14. In this position, the middle part 1 can pivot freely around the turning axis 201-211, being guided by the guide pivots 251, 261, between the two opposite horizontal positions illustrated in FIGS. 4 and 7. The wearer of the watch then pushes the middle part 1 to fold the arms 20 and 21 and reach the second rest position illustrated in FIG. 10, with the second face 11 visible. The middle part 1 is held in this position by the spring balls, not shown, engaged in other holes 28 on the internal faces of the horns 171.
Les coulisses 250, 260 solidaires de la carrure 1 sont des pièces d'usure. Dans une variante préférentielle, les porte-coulisses 25, 26 peuvent donc être remplacés sans changer toute la carrure. Ils sont donc de préférence rapportés ou vissés sur les faces frontales de la carrure 1 par des vis engagées dans les trous 24; les porte-coulisses 25, 26 peuvent aussi cacher des vis non représentées permettant d'ouvrir la carrure 1 pour la maintenance ou le remplacement de la batterie.The slides 250, 260 integral with the middle part 1 are wearing parts. In a preferred variant, the slide carriers 25, 26 can therefore be replaced without changing the entire middle part. They are therefore preferably attached or screwed onto the front faces of the middle part 1 by screws engaged in the holes 24; the slide carriers 25, 26 can also hide screws, not shown, making it possible to open the middle part 1 for maintenance or replacement of the battery.
On constatera que le dispositif décrit permet de retourner aisément la carrure 1 sans devoir retirer le bracelet 13. On constatera aussi que la plus grande portion des différentes coulisses est masquée par les bras 20, 21, les porte-coulisses 25, 26 et la carrure 1 dans toutes les positions, notamment dans les positions de repos, en sorte que le risque d'obstruction est fortement réduit.It will be noted that the device described makes it possible to easily turn over the middle part 1 without having to remove the strap 13. It will also be noted that the largest portion of the different slides is hidden by the arms 20, 21, the slide holders 25, 26 and the middle part 1 in all positions, in particular in the rest positions, so that the risk of obstruction is greatly reduced.
La montre réversible de l'invention comprend avantageusement deux mouvements distincts 12, 19 (figure 19) logés l'un contre l'autre dans la carrure 1. Le premier mouvement 12 est un mouvement mécanique à remontage manuel ou automatique, permettant d'afficher l'heure, et éventuellement des fonctions supplémentaires, par exemple un chronographe, au moyen des aiguilles 100 sur la première face 10 de la montre. Le deuxième mouvement 19 est un mouvement électronique, par exemple un mouvement à quartz, permettant d'afficher d'autres indications, par exemple une deuxième heure, la date, etc., sur l'affichage à cristaux liquides 110 de la deuxième face 11. La montre combine ainsi les avantages d'un affichage à aiguilles avec ceux d'un affichage alphanumérique, ainsi que les avantages d'un mouvement mécanique (prestige, fonctionnement sans batterie) avec ceux d'un mouvement à quartz.The reversible watch of the invention advantageously comprises two distinct movements 12, 19 (FIG. 19) housed one against the other in the middle part. The first movement 12 is a mechanical movement with manual or automatic winding, making it possible to display the time, and possibly additional functions, for example a chronograph, by means of the hands 100 on the first face 10 of the watch. The second movement 19 is an electronic movement, for example a quartz movement, making it possible to display other indications, for example a second time, the date, etc., on the liquid crystal display 110 of the second face 11 The watch thus combines the advantages of a needle display with those of an alphanumeric display, as well as the advantages of a mechanical movement (prestige, operation without battery) with those of a quartz movement.
Un deuxième mode de réalisation de l'invention est illustré sur les figures 15 à 18. Ce deuxième mode de réalisation a l'avantage de ne pas nécessiter de coulisses dans la carrure 1, ce qui permet d'utiliser une carrure plus fine. Les coulisses sont par ailleurs des éléments fragiles, susceptibles de se bloquer en cas de chocs mécaniques ou d'obstructions par des poussières ou des déchets de peau par exemple. Ce mode de réalisation a A second embodiment of the invention is illustrated in FIGS. 15 to 18. This second embodiment has the advantage of not requiring slides in the middle part 1, which makes it possible to use a thinner middle part. The slides are also fragile elements, liable to block in the event of mechanical shock or obstruction by dust or skin waste, for example. This embodiment has
toutefois l'inconvénient de ne pas entièrement exclure le risque de contact entre la carrure ou les organes de commande et le cadre, comme on le verra plus loin.however, the drawback of not entirely excluding the risk of contact between the middle part or the control members and the frame, as will be seen below.
La montre selon le deuxième mode de réalisation de l'invention est représentée sur la figure 15 en position repliée avec la face 10 comportant un affichage analogique à aiguilles 100 visible sur le dessus. Elle comporte une carrure 1 reliée de manière articulée à un cadre extérieur 17 au moyen de deux bras 22, 23. Les bras sont articulés par rapport au cadre 17 autour d'axes de rotation 220, 230 (figure 12) en regard l'un de l'autre, approximativement à 6 heures et à 12 heures. La carrure 1 est apte à pivoter par rapport aux deux bras 22, 23 autour d'un axe de retournement défini par les deux pivots 221, 231.The watch according to the second embodiment of the invention is shown in FIG. 15 in the folded position with the face 10 comprising an analog display with hands 100 visible on the top. It has a middle part 1 hingedly connected to an outer frame 17 by means of two arms 22, 23. The arms are articulated relative to the frame 17 about axes of rotation 220, 230 (FIG. 12) facing one on the other, approximately at 6 a.m. and 12 p.m. The middle part 1 is able to pivot with respect to the two arms 22, 23 about an axis of turning defined by the two pivots 221, 231.
Dans cette variante, comme on le voit sur les figures 16 et 17 en particulier, les deux bras 22 et 23 restent en tout temps parallèles entre eux. La carrure 1 illustrée est carrée ou rectangulaire ; la longueur des deux bras 22, 23 est inférieure à la largeur de cette carrure, mais suffisante pour permettre un retournement de la carrure, lorsque les bras sont entièrement dépliés perpendiculairement à leur position initiale, sans que les organes de commande 14, 15, 16 ou d'autres portions de la carrure n'entrent en contact avec le cadre 17. La longueur des deux bras 22, 23 doit donc être suffisante pour que la distance entre les axes de rotation 220, 230 et l'axe de retournement 221, 231 soit supérieure à la somme de la demi-largeur de la carrure augmentée de l'épaisseur desdits organes de commande.In this variant, as can be seen in FIGS. 16 and 17 in particular, the two arms 22 and 23 remain parallel to each other at all times. The middle 1 illustrated is square or rectangular; the length of the two arms 22, 23 is less than the width of this middle part, but sufficient to allow the middle part to be turned over, when the arms are fully extended perpendicular to their initial position, without the control members 14, 15, 16 or other portions of the middle part come into contact with the frame 17. The length of the two arms 22, 23 must therefore be sufficient so that the distance between the axes of rotation 220, 230 and the axis of turning 221, 231 is greater than the sum of the half-width of the middle part increased by the thickness of said control members.
L'axe de retournement, défini comme la droite traversant les deux pivots 221, 231, traverse la carrure selon une direction fixe parallèle au diamètre 6 heures - 12 heures, mais différente de ce diamètre. La carrure 1 étant fixée aux bras 22, 23 par des axes sans coulisses, l'angle entre cet axe de retournement et la carrure 1 reste constant tout au long du retournement. La liaison entre les bras 22, 23 et la carrure est donc plus rigide que dans le premier mode de réalisation. The turning axis, defined as the straight line crossing the two pivots 221, 231, crosses the middle in a fixed direction parallel to the 6 o'clock - 12 o'clock diameter, but different from this diameter. The middle 1 being fixed to the arms 22, 23 by axes without slides, the angle between this turning axis and the middle 1 remains constant throughout the turning. The connection between the arms 22, 23 and the middle part is therefore more rigid than in the first embodiment.
Dans la position de repos illustrée sur la figure 15 avec la face analogique 10 visible, et sur la figure 18 avec la face numérique 11 visible, les bras 22, 23 viennent se loger en position repliée dans un évidement de la carrure 1. Le mécanisme de retournement est donc très peu visible en position repliée.In the rest position illustrated in FIG. 15 with the analog face 10 visible, and in FIG. 18 with the digital face 11 visible, the arms 22, 23 are housed in the folded position in a recess of the middle part 1. The mechanism is therefore very little visible in the folded position.
Pour retourner la carrure 1 et choisir la face 10 ou 11 à afficher, le porteur de la montre soulève la carrure 1 depuis la position de repos illustrée sur la figure 15 pour dégager les billes sur ressort des trous 28, puis fait pivoter les deux bras 22, 23 dans un plan vertical jusqu'à ce que la carrure 1 soit suffisamment éloignée du cadre 17 pour permettre la rotation sans collision de la carrure. La carrure peut alors être pivotée facilement autour de l'axe de retournement 221, 231 pour choisir la face visible 10 ou 11 à afficher. Les bras poursuivent ensuite leur rotation de 180° pour se replier dans l'autre position de repos illustrée sur la figure 18. Par rapport à la première variante, les organes de commande 14,To turn over the middle part 1 and choose the side 10 or 11 to be displayed, the wearer of the watch lifts the middle part 1 from the rest position illustrated in FIG. 15 to release the balls on the spring from the holes 28, then pivot the two arms 22, 23 in a vertical plane until the middle 1 is sufficiently distant from the frame 17 to allow the rotation without collision of the middle. The middle part can then be easily pivoted around the turning axis 221, 231 to choose the visible face 10 or 11 to be displayed. The arms then continue their rotation of 180 ° to fold back into the other rest position illustrated in FIG. 18. Compared to the first variant, the control members 14,
15 et 16 peuvent éventuellement dans cette deuxième variante entrer en contact avec le fond du cadre 17 si la carrure est retournée trop rapidement ou trop tardivement, c'est-à-dire lorsque l'angle α parcouru par les bras 22, 23 est sensiblement différent de 90°. En effet, les deux pivots 221, 231 étant toujours alignés, un retournement est possible en n'importe quel point. Par ailleurs, la carrure 1 ne reste pas horizontale durant toutes les phases du déplacement. 15 and 16 may possibly in this second variant come into contact with the bottom of the frame 17 if the middle part is turned too quickly or too late, that is to say when the angle α traversed by the arms 22, 23 is substantially different from 90 °. Indeed, the two pivots 221, 231 being always aligned, a reversal is possible at any point. Furthermore, the middle part 1 does not remain horizontal during all the phases of the movement.
