Description

Domaine technique et état de l'artTechnical field and state of the art

L'invention concerne un chronomètre mécanique de marine, comprenant une montre généralement de grand format destinée à conserver le temps sur les bateaux. De manière connue, une telle montre comprend, dans un boîtier, un mouvement mécanique entraîné par un barillet, une telle montre est fixée à un support par l'intermédiaire d'une suspension à cardan de sorte que la montre est inclinable dans toutes les directions par rapport au support. La suspension à cardan assure ainsi à la montre et plus précisément à l'oscillateur de la montre une position horizontale quels que soient les mouvements du bateau. Une suspension à cardan est toutefois fragile et supporte assez mal les déplacements, les chocs, notamment du fait du poids de la montre qu'elle porte. Également, un chronomètre de marine doit pouvoir être utilisé dans des conditions climatiques difficiles et doit en particulier résister à l'eau. Ainsi, de manière connue, la montre est équipée d'un boîtier étanche à l'eau. Le remontage du barillet du chronomètre nécessite toutefois une intervention manuelle depuis l'extérieur du boîtier de la montre.The invention relates to a mechanical marine chronometer, comprising a generally large format watch intended to keep time on boats. In known manner, such a watch comprises, in a case, a mechanical movement driven by a barrel, such a watch is fixed to a support by means of a gimbal suspension so that the watch is tiltable in all directions. relative to the support. The gimbal suspension thus ensures that the watch and more precisely the oscillator of the watch has a horizontal position regardless of the movements of the boat. However, a gimbal suspension is fragile and does not withstand movement and shock quite badly, in particular due to the weight of the watch it is carrying. Also, a marine chronometer must be able to be used in difficult climatic conditions and must in particular be resistant to water. Thus, in a known manner, the watch is equipped with a waterproof case. However, winding the chronometer barrel requires manual intervention from outside the watch case.

La publication de brevet D1 = CH2960 décrit un boîtier pour un chronomètre de marine avec un mécanisme de remontage mécanique. Sur l'axe de fusée est fixé un pignon F de dents à rochet. Sur le prolongement de cet axe, au fond du boîtier, est monté un pignon de remontage F' de taillage semblable monté coulissant pour engrener avec le pignon F en position de remontage. A l'extérieur du boîtier, une roue dentée D est montée sur l'axe du pignon de remontage F', ladite roue dentée étant couplée à un pignon conique C fixé à une extrémité d'une tige de remontoir. (les références sont ici celles de la fig. 1 de D1). L'étanchéité de la zone où l'axe portant le pignon de remontage traverse le boîtier de la montre est généralement assurée par un joint d'étanchéité ; cette étanchéité n'est toutefois pas toujours garantie quelles que soient les conditions d'utilisation. Notamment, lors d'une mise à l'heure ou d'un remontage, l'efficacité du joint d'étanchéité est diminuée lors de la translation de l'axe portant le pignon F' de remontage. Au surplus, un système de remontage tel que celui décrit dans D1 est peu fiable du fait d'un glissement possible entre la roue dentée D et la roue d'entraînement C conique.Patent publication D1=CH2960 describes a case for a marine chronometer with a mechanical winding mechanism. On the spindle axis is fixed a pinion F with ratchet teeth. On the extension of this axis, at the bottom of the case, is mounted a winding pinion F' of similar cutting mounted sliding to mesh with the pinion F in the winding position. Outside the case, a toothed wheel D is mounted on the axis of the winding pinion F', said toothed wheel being coupled to a bevel pinion C fixed to one end of a winding stem. (the references here are those of the fig. 1 of D1). The watertightness of the area where the axle carrying the winding pinion passes through the case of the watch is generally ensured by a seal ; this tightness is however not always guaranteed whatever the conditions of use. In particular, when setting the time or winding, the effectiveness of the seal is reduced during the translation of the shaft carrying the winding pinion F'. Moreover, a winding system such as that described in D1 is unreliable due to possible slippage between the toothed wheel D and the conical drive wheel C.

On connait également du document CH 89275 un chronomètre de marine monté pivotant selon un premier axe dans un anneau de support. Ce chronomètre comprend pour le remontage du barillet un organe de commande de remontage positionné à l'extérieur de la boite. L'organe de commande de remontage est solidaire d'une roue dentée qui engrène avec une denture solidaire d'une douille montée dans le fond de la boite. Lors du montage du mouvement dans la boite, l'axe de barillet vient se positionner dans la douille et peut être commandé par l'organe de commande.We also know from the document CH 89275 a marine chronometer pivotally mounted along a first axis in a support ring. This chronometer comprises, for winding the barrel, a winding control member positioned outside the case. The winding control member is secured to a toothed wheel which meshes with a set of teeth secured to a socket mounted in the bottom of the case. When the movement is mounted in the case, the barrel pin is positioned in the sleeve and can be controlled by the control device.

Description de l'inventionDescription of the invention

La présente demande de brevet propose un nouveau chronomètre de marine, ne présentant pas au moins un des inconvénients des chronomètres de marine connus tels qu'exposés ci-dessus.This patent application proposes a new marine chronometer, which does not have at least one of the drawbacks of known marine chronometers as set out above.

Plus précisément, la présente invention propose un chronomètre de marine comprenant une montre montée sur un support, par exemple montée inclinable par rapport au support par l'intermédiaire d'une suspension à cardan ; la montre comprend, dans un boîtier, un mouvement mécanique entraîné par un barillet ; la montre comprend également un organe de commande de remontage en prise avec un rouage de remontage du barillet.More precisely, the present invention proposes a marine chronometer comprising a watch mounted on a support, for example mounted tilting with respect to the support by means of a gimbal suspension; the watch comprises, in a case, a mechanical movement driven by a barrel; the watch also includes a winding control member engaged with a winding gear train of the barrel.

Le chronomètre selon l'invention est caractérisé en ce que l'organe de commande de remontage comprend un rouage de commande de remontage positionné à l'extérieur de la montre, solidaire d'un axe traversant une paroi du boîtier par l'intermédiaire d'un palier, ledit axe traversant étant en prise avec le rouage de remontage du barillet.The chronometer according to the invention is characterized in that the winding control member comprises a winding control cog positioned outside the watch, secured to an axis passing through a wall of the case via a bearing, said through axle being in mesh with the barrel winding gear train.

Le palier autorise la rotation de l'organe de commande de remontage, notamment pour permettre le remontage du barillet, mais interdit tout déplacement en translation de l'axe traversant la paroi du boîtier de la montre. Les conditions d'étanchéité au niveau du palier sont ainsi les mêmes, que le moyen de remontage soit en position de repos ou en position de remontage. Par ailleurs, comme le rouage de commande de remontage est positionné à l'extérieur du boîtier, il peut être couplé à un moyen de remontage sans intervention à l'intérieur du boîtier ; l'étanchéité est ainsi maîtrisée.The bearing allows rotation of the winding control member, in particular to allow winding of the barrel, but prohibits any movement in translation of the axis passing through the wall of the case of the watch. The sealing conditions at the level of the bearing are thus the same whether the winding means is in the rest position or in the winding position. Furthermore, as the winding control gear train is positioned outside the case, it can be coupled to a winding means without intervention inside the case; sealing is thus controlled.

Le palier peut comprendre, sur une paroi intérieure, au moins une gorge dans laquelle est logé un joint améliorant l'étanchéité du boîtier. Le joint est par exemple un joint torique. Lors d'un remontage, le joint est soumis uniquement à des efforts radiaux dus aux rotations l'axe traversant de l'organe de commande de remontage, mais pas à des efforts latéraux de sorte que le joint ne peut pas être déplacé ou déformé. L'étanchéité du boîtier est ainsi parfaitement maintenue, y compris pendant le remontage du barillet.The bearing may comprise, on an inner wall, at least one groove in which is housed a seal improving the tightness of the housing. The seal is for example an O-ring. During winding, the seal is subjected only to radial forces due to rotations of the axis passing through the winding control member, but not to lateral forces so that the seal cannot be moved or deformed. The tightness of the case is thus perfectly maintained, including during winding of the barrel.

Le chronomètre selon l'invention comprend également un moyen de couplage comprenant un rouage de couplage mobile entre une position de couplage où le rouage de commande de remontage de la montre et le rouage de couplage sont couplés mécaniquement et une position de repos où le rouage de commande de remontage de la montre est indépendant du moyen de couplage. Ainsi réalisé, le moyen de couplage permet de ne pas déplacer en translation l'organe de commande de remontage lié au barillet, par exemple pour un remontage du barillet.The chronometer according to the invention also comprises a coupling means comprising a coupling gear train movable between a coupling position where the watch winding control gear train and the coupling gear train are mechanically coupled and a rest position where the winding control of the watch is independent of the coupling means. Thus produced, the coupling means makes it possible not to move in translation the winding control member linked to the barrel, for example for winding of the barrel.

Selon un mode de réalisation, le moyen de couplage comprend également un axe de maintien et un mécanisme de levage pour coulisser le rouage de couplage le long de l'axe de maintien entre la position de couplage et la position de repos. Le mécanisme de levage peut être par exemple de type ciseaux et peut être par exemple actionné manuellement par un levier.According to one embodiment, the coupling means also comprises a retaining pin and a lifting mechanism for sliding the coupling gear train along the retaining pin between the coupling position and the rest position. The lifting mechanism may for example be of the scissor type and may for example be actuated manually by a lever.

De préférence, l'organe de commande de remontage et le moyen de couplage sont positionnés sous le boîtier de la montre de sorte que, lorsque le rouage de couplage est en position de couplage, la montre est en appui sur le moyen de couplage. Ainsi, en position de couplage, le rouage de couplage et son axe de maintien supportent le poids de la montre. Si de plus la montre est montée mobile, par exemple inclinable sur une suspension à cardan, la montre est immobilisée en appui sur l'organe d'entraînement. La montre est donc verrouillée en position concentrique à l'axe central du boîtier, position verrouillée qui évite les mouvements désordonnés de la montre lors de transports, hors fonction de garde temps sur un bateau.Preferably, the winding control member and the coupling means are positioned under the case of the watch so that, when the coupling gear train is in the coupling position, the watch is resting on the coupling means. Thus, in the coupling position, the coupling gear train and its retaining pin support the weight of the watch. If moreover the watch is mounted mobile, for example tiltable on a gimbal suspension, the watch is immobilized in support on the drive member. The watch is therefore locked in a position concentric with the central axis of the case, a locked position which avoids disorderly movements of the watch during transport, except as a timekeeper on a boat.

Le chronomètre peut également comprendre un moyen de remontage comprenant un mécanisme d'entraînement en rotation du rouage de couplage, pour permettre à un utilisateur de remonter le barillet.The chronometer can also include winding means comprising a mechanism for driving the coupling gear in rotation, to enable a user to wind the barrel.

En complément, le moyen de remontage peut comprendre un mécanisme de débrayage adapté pour isoler le moyen de couplage du mécanisme d'entraînement en rotation lorsque le barillet a atteint une position remontée. Ceci permet d'éviter de casser la montre et / ou le moyen de remontage en cas d'effort excessif de l'utilisateur.In addition, the winding means may include a release mechanism suitable for isolating the coupling means from the rotation drive mechanism when the barrel has reached a raised position. This makes it possible to avoid breaking the watch and/or the winding means in the event of excessive effort by the user.

Description d'un mode de réalisation de l'inventionDescription of an embodiment of the invention

Comme dit précédemment, l'invention concerne un chronomètre de marine comprenant une montre 10 montée sur un support 1. Sur la fig. 1, la montre est montée inclinable par rapport au support par l'intermédiaire d'une suspension à cardan et est installée dans un boîtage 1. Dans l'exemple représenté, la montre 10 comprend un boîtier 11 en forme de portion de sphère, boîtier dans lequel est logé un mouvement horloger mécanique classique de la montre dont les moyens moteurs, connus, sont formés par un barillet B en prise avec un rouage de remontage Ba. Le boîtier 11 est fermé classiquement de manière étanche par une glace sous laquelle sont positionnés un cadran et des aiguilles (fig. 1), ainsi que le mouvement horloger. La suspension à cardan de la montre 10, également connue en soi, est représentée simplement par un anneau 12 de suspension ; les liaisons mécaniques entre l'anneau 12 et le support ne sont pas détaillées par souci de clarté des figures.As said above, the invention relates to a marine chronometer comprising a watch 10 mounted on a support 1. On the fig. 1 , the watch is mounted tilting relative to the support by means of a gimbal suspension and is installed in a case 1. In the example shown, the watch 10 comprises a case 11 in the form of a portion of a sphere, a case in which is housed a conventional mechanical watch movement of which the motor means, known, are formed by a barrel B engaged with a winding gear train Ba. The case 11 is conventionally sealed in a sealed manner by a crystal under which are positioned a dial and hands ( fig. 1 ), as well as the watch movement. The gimbal suspension of the watch 10, also known per se, is represented simply by a suspension ring 12; the mechanical connections between the ring 12 and the support are not detailed for the sake of clarity of the figures.

La montre selon l'invention comprend également un organe de commande 13 de remontage comprenant un rouage de commande de remontage 14 positionné à l'extérieur de la montre. Selon le mode de réalisation représenté, le rouage de commande de remontage 14 comprend un flasque 14a, et une pluralité de dents 14b taillées sur une face de dessous du flasque 14 du rouage de commande de remontage. Le rouage 14 est solidaire d'un axe 15 traversant une paroi du boîtier 11 par l'intermédiaire d'un palier 11a ; et l'axe traversant 15 est en prise avec le rouage de remontage (Ba) du barillet. Dans l'exemple représenté, le palier 11a comprend, sur une paroi intérieure, deux gorges dans lesquelles sont logés deux joints 11b toriques complétant l'étanchéité du boîtier 11 au niveau de l'axe 15.The watch according to the invention also comprises a winding control member 13 comprising a winding control gear train 14 positioned outside the watch. According to the embodiment represented, the winding control train 14 comprises a flange 14a, and a plurality of teeth 14b cut on a bottom face of the flange 14 of the winding control train. The gear train 14 is integral with a shaft 15 passing through a wall of the case 11 via a bearing 11a; and the through axle 15 engages with the winding gear train (Ba) of the barrel. In the example shown, the bearing 11a comprises, on one inner wall, two grooves in which are housed two O-rings 11b completing the sealing of the housing 11 at the level of the axis 15.

Le chronomètre selon l'invention comprend également un moyen de couplage 20 comprenant un rouage de couplage 21 mobile entre :

  • une position de couplage où le rouage de commande de remontage 14 de la montre et le rouage de couplage sont couplés mécaniquement et
  • une position de repos où le rouage de commande de remontage 14 est indépendant du moyen de remontage.
The stopwatch according to the invention also comprises a coupling means 20 comprising a coupling gear train 21 movable between:
  • a coupling position where the winding control gear train 14 of the watch and the coupling gear train are mechanically coupled and
  • a rest position where the winding control train 14 is independent of the winding means.

Selon le mode de réalisation représenté, le rouage de couplage 21 comprend un flasque 21a et une pluralité de dents 21b taillées sur une face de dessus du flasque 21a du rouage de couplage 21 et agencées de sorte que le rouage de couplage 21 puisse entraîner en rotation le rouage de commande de remontage 14 (couplage mécanique par crabotage) lorsque le rouage de couplage est en position de remontage. Le moyen de couplage 20 comprend également un axe de maintien 22 et un mécanisme de levage 30 pour coulisser le rouage de couplage 21 le long de l'axe de maintien 22 entre la position de couplage et la position de repos.According to the embodiment shown, the coupling gear 21 comprises a flange 21a and a plurality of teeth 21b cut on a top face of the flange 21a of the coupling gear 21 and arranged so that the coupling gear 21 can rotate the winding control gear train 14 (mechanical coupling by dog clutch) when the coupling gear train is in the winding position. The coupling means 20 also comprises a retaining pin 22 and a lifting mechanism 30 for sliding the coupling gear train 21 along the retaining pin 22 between the coupling position and the rest position.

Dans l'exemple représenté, l'organe de commande de remontage 13 et le moyen de couplage 20 sont positionnés sous le boîtier de la montre de sorte que, lorsque le rouage de couplage est en position de couplage, la montre est en appui sur l'organe d'entraînement 20.In the example shown, the winding control member 13 and the coupling means 20 are positioned under the case of the watch so that, when the coupling gear train is in the coupling position, the watch is resting on the drive member 20.

Dans l'exemple représenté, le mécanisme de levage 30 est de type ciseaux (figs. 3-4), susceptible d'être mis en mouvement manuellement par un utilisateur via un levier 33. Le mécanisme 30 comprend ici quatre paires de bielles (figs. 2-4). Chaque paire de bielles comprend deux bielles 34, 35 associées en ciseaux et les paires de bielle sont associées deux à deux. Une bielle 34 comprend un pied articulé par une liaison pivot avec le support 1 et une tête articulée par une liaison pivot avec une tête d'une bielle 35 associée ; la dite bielle 35 associée comprend également un pied articulé mécaniquement par une liaison pivot 35a avec le tube de liaison 21a du berceau et avec un pied d'une autre bielle 35 d'une paire de bielles associées. Le levier 33 a quant à lui dans l'exemple représenté comporte deux côtés avec une forme sensiblement en T ; une extrémité libre d'un grand côté du levier forme un manche 37 de préhension ; les deux extrémités 36a, 36b du petit côté 38 forment des butées et sont un élément esthétique; une butée 36a en position de repos et l'autre butée 36b en position de maintien et / ou de remontage. Au repos, chaque paire de bielles 34, 35 forme un ciseau fermé (fig. 3-4). Une traction / rotation sur le manche 37 du levier entraîne l'ouverture simultanée des paires de bielles, entraînant le rouage 21 en translation selon la direction de l'axe de maintien 22 jusqu'à la position de maintien : l'organe de commande de remontage 13 est alors en appui sur l'organe d'entraînement 20 comprenant le rouage 21 la montre n'est donc plus seulement en appui sur la suspension à cardan et est ainsi immobilisée.In the example shown, the lifting mechanism 30 is of the scissor type ( figs. 3-4 ), capable of being set in motion manually by a user via a lever 33. The mechanism 30 here comprises four pairs of connecting rods ( figs. 2-4 ). Each pair of connecting rods comprises two connecting rods 34, 35 associated in scissors and the connecting rod pairs are associated two by two. A connecting rod 34 comprises a foot articulated by a pivot connection with the support 1 and a head articulated by a pivot connection with a head of an associated connecting rod 35; said associated connecting rod 35 also comprises an articulated foot mechanically by a pivot connection 35a with the connection tube 21a of the cradle and with a foot of another connecting rod 35 of a pair of associated connecting rods. The lever 33 has meanwhile in the example shown has two sides with a substantially T-shape; a free end of a large side of the lever forms a handle 37 for gripping; the two ends 36a, 36b of the short side 38 form abutments and are an aesthetic element; a stop 36a in the rest position and the other stop 36b in the holding and/or winding position. At rest, each pair of connecting rods 34, 35 form a closed scissor ( fig. 3-4 ). Traction/rotation on the handle 37 of the lever causes the simultaneous opening of the pairs of connecting rods, driving the gear train 21 in translation in the direction of the holding pin 22 up to the holding position: the control member of winding 13 is then resting on the drive member 20 comprising the gear train 21 the watch is therefore no longer resting solely on the gimbal suspension and is thus immobilized.

Sur les figures, le moyen de couplage 20 comprend un rouage de liaison 22a ; le moyen de remontage quant à lui comprend un mécanisme d'entraînement en rotation du moyen de couplage 20 et un mécanisme de débrayage adapté pour isoler le moyen de couplage 20 du mécanisme d'entraînement en rotation lorsque le barillet a atteint une position remontée. Le mécanisme de mise en rotation 40 représenté fig. 5 comprend :

  • un axe de mise en mouvement 41 dont une extrémité libre 41a est adaptée à recevoir un dispositif d'entraînement manuel tel qu'une clé, une manivelle, une molette, une couronne, ou un dispositif d'entraînement à assistance électrique,
  • un organe d'entraînement 43 comprenant un rouage 43a en prise avec le rouage de liaison 22a et un pignon crabot 43b, ledit organe d'entraînement 43 étant monté rotatif sur l'axe de mise en mouvement 41,
  • un pignon de débrayage 45 complémentaire du pignon crabot 43a et maintenu en prise avec le pignon crabot 43b par un moyen de rappel élastique 46, le pignon crabot 43b ; le pignon de débrayage 45 et le moyen de rappel élastique 46 forment ensemble le mécanisme de débrayage du moyen de remontage.
In the figures, the coupling means 20 comprises a connecting gear 22a; the winding means for its part comprises a drive mechanism in rotation of the coupling means 20 and a disengagement mechanism adapted to isolate the coupling means 20 from the drive mechanism in rotation when the barrel has reached a raised position. The rotation mechanism 40 shown fig. 5 understand :
  • a movement shaft 41, one free end 41a of which is adapted to receive a manual drive device such as a key, a crank, a knob, a crown, or an electrically assisted drive device,
  • a drive member 43 comprising a gear train 43a engaged with the connecting gear train 22a and a dog clutch pinion 43b, said drive member 43 being rotatably mounted on the movement shaft 41,
  • a clutch pinion 45 complementary to the dog pinion 43a and held in engagement with the dog pinion 43b by an elastic return means 46, the dog pinion 43b; the clutch pinion 45 and the means elastic return 46 together form the disengagement mechanism of the winding means.

Le moyen de remontage du chronomètre selon le mode de réalisation représenté sur les figures est utilisé de la manière suivante. En position de repos (figs. 3-4), l'organe d'entraînement 20 repose sur le support 1 et est éloigné de la montre ; l'organe de commande de remontage 13 de la montre et l'organe d'entraînement 20 sont éloignés les uns des autres de sorte qu'il n'y a pas de couplage mécanique entre eux ; la montre est ainsi libre de mouvement sur la suspension à cardan.The chronometer winding means according to the embodiment shown in the figures is used as follows. In rest position ( figs. 3-4 ), drive member 20 rests on support 1 and is remote from the watch; the winding control member 13 of the watch and the drive member 20 are remote from each other so that there is no mechanical coupling between them; the watch is thus free to move on the gimbal suspension.

Lorsque l'utilisateur tire sur le manche 37 du levier 33, l'organe d'entraînement 20 est levé par le mécanisme de levage 30 ; lorsque le rouage d'entraînement 21 de l'organe 20 arrive en contact avec l'organe de commande de remontage 13 de la montre, et plus précisément avec le rouage de commande de remontage 14, le rouage 21 fait pivoter le rouage 14 et la montre jusqu'à la position de remontage où l'axe du rouage 21 et l'axe du rouage 14 de la montre sont alignés. Le couplage mécanique entre le rouage 21 et le rouage 14 est maximal, la montre repose sur le rouage 21 de sorte que la suspension à cardan est soulagée du poids de la montre. La montre est ainsi immobilisée sur le moyen de couplage 20, par exemple pour être transportée ou remontée.When the user pulls on the handle 37 of the lever 33, the drive member 20 is lifted by the lifting mechanism 30; when the drive train 21 of the member 20 comes into contact with the winding control member 13 of the watch, and more precisely with the winding control train 14, the train 21 causes the train 14 to pivot and the watch up to the winding position where the axis of the gear train 21 and the axis of the gear train 14 of the watch are aligned. The mechanical coupling between gear train 21 and gear train 14 is maximum, the watch rests on gear train 21 so that the gimbal suspension is relieved of the weight of the watch. The watch is thus immobilized on the coupling means 20, for example to be transported or reassembled.

Par ailleurs, comme le rouage de liaison 22a est en prise avec le rouage d'entraînement 43a, le rouage 21 est en prise avec le rouage de couplage 43a de sorte qu'une rotation d'une clé à l'extrémité libre 41a de l'axe 41 entraîne en rotation le rouage de couplage 43a, qui entraîne à son tour en rotation le rouage de liaison 22a, l'axe de maintien 22 et le rouage d'entraînement 21. A son tour, le rouage d'entraînement 21 entraîne en rotation l'organe de commande de remontage 13 par couplage mécanique, ce qui permet de remonter le barillet de la montre.Furthermore, as the link cog 22a is meshed with the drive cog 43a, the cog 21 is meshed with the coupling cog 43a so that a rotation of a key at the free end 41a of the axis 41 rotates the coupling gear 43a, which in turn rotates the connecting gear 22a, the retaining pin 22 and the drive train 21. In turn, the drive train 21 drives in rotation the winding control member 13 by mechanical coupling, which makes it possible to wind the barrel of the watch.

Dans l'exemple qui vient d'être décrit un mécanisme du type ciseaux est utilisé pour lever et abaisser le moyen d'entraînement 20 mais il est bien entendu que selon des variantes d'autres type de mécanismes de levage peuvent être envisagés, à titre d'exemple on pourrait prévoir un mécanisme du type genou simple ou à deux bielles ou encore un mécanisme du type presse à genoux ou encore un système à vérins par exemple des vérins à vis télescopique ou non. De tels mécanismes sont décrits notamment aux pages 144 et 145 de l'ouvrage intitulé « Des Mécanismes Elémentaires » édité par Decoopman, No ISBN 97823650027.In the example which has just been described, a scissor-type mechanism is used to raise and lower the drive means 20 but it is understood that according to variants other types of lifting mechanisms can be envisaged, as for example one could provide a mechanism of the simple knee type or with two connecting rods or even a mechanism of the knee press type or even a system with jacks, for example screw jacks, telescopic or not. Such mechanisms are described in particular on pages 144 and 145 of the work entitled “Elementary Mechanisms” edited by Decoopman, ISBN No. 97823650027.
