Description

L'invention est relative à un dispositif de fermeture, en particulier une serrure, à encastrer dans un battant de porte, de porte-fenêtre ou de fenêtre.The invention relates to a closure device, in especially a lock, to be embedded in a door leaf, of a French window or window.

L'invention concerne un dispositif de fermeture destiné à la manoeuvre d'au moins une tringle montée coulissante sur le chant du battant, la tringle portant des organes de verrouillage, et qui comporte:

  • un boítier plat à encastrer, contenant un pêne ;
  • un fouillot monté rotatif dans le boítier autour d'un axe géométrique orthogonal au plan moyen du boítier, ce fouillot pouvant être entraíné en rotation par une poignée, en particulier une béquille, le fouillot étant muni d'un bras de fouillot qui commande la tringle en coulissement, le bras de fouillot étant décentré relativement au fouillot de manière à tourner autour d'un point plus éloigné de la tringle que le centre de rotation du fouillot ;
  • un moyen étant prévu pour entraíner directement en rotation par le fouillot le bras de fouillot décentré, sans pièce intermédiaire, le moyen pour entraíner le bras de fouillot comprenant un doigt lié au fouillot et logé dans un évidement d'un moyeu du bras de fouillot.
The invention relates to a closing device intended for the operation of at least one rod mounted to slide on the edge of the leaf, the rod carrying locking members, and which comprises:
  • a flat recessed box, containing a bolt;
  • a nut rotatably mounted in the housing around a geometric axis orthogonal to the mean plane of the housing, this follower can be rotated by a handle, in particular a stand, the follower being provided with a follower arm which controls the rod in sliding, the follower arm being off-center relative to the follower so as to rotate around a point further from the rod than the center of rotation of the follower;
  • means being provided for directly driving in rotation by the follower the off-center follower arm, without intermediate piece, the means for driving the follower arm comprising a finger linked to the follower and housed in a recess in a hub of the follower arm.

Dans un dispositif de fermeture, notamment une serrure, à encastrer classique, la distance entre l'axe du fouillot et une pièce, ou têtière, solidaire du boítier appliquée contre le chant du battant revêt une importance particulière. Cette distance, appelée "entrée de serrure" correspond à la distance entre le trou pratiqué dans le battant pour le passage de la tige d'entraínement commandée par la béquille, et le chant de porte. La tendance est à réduire cette distance. Il en résulte qu'il faut également diminuer l'''entrée" de la serrure à encastrer par exemple dans une porte.In a closing device, in particular a lock, with conventional recess, the distance between the axis of the follower and a part, or headrest, integral with the housing applied against the edge of the leaf, has a particular importance. This distance, called "lock entry" corresponds to the distance between the hole made in the leaf for the passage of the drive rod controlled by the stand, and the song door. The tendency is to reduce this distance. The result is that also reduce the "entry" of the mortise lock for example in a door.

Ceci crée un problème pour l'obtention d'un déplacement de tringle suffisant en vue d'assurer la fermeture du battant, notamment de porte. En effet, le déplacement de la tringle dépend, d'une part, de la longueur effective du bras de fouillot qui attaque, par une extrémité, la tringle pour transformer un mouvement de rotation en un mouvement de translation, et, d'autre part, de l'angle de rotation de ce bras de fouillot. L'angle de rotation de la béquille est généralement imposé par le cahier des charges et a une valeur voisine de 45°.This creates a problem for obtaining a displacement of rod sufficient to ensure the closure of the leaf, in particular of door. Indeed, the displacement of the rod depends, on the one hand, on the effective length of the follower arm which attacks, by one end, the rod to transform a rotational movement into a movement of translation, and, on the other hand, the angle of rotation of this follower arm. The angle of rotation of the stand is generally imposed by the notebook loads and has a value close to 45 °.

Dans un système d'entraínement simple, selon lequel le fouillot transmet au bras de fouillot le déplacement angulaire de la béquille, il est clair qu'une diminution du rayon effectif du bras de fouillot entraíne, pour un même angle de rotation, une course périphérique de l'extrémité du bras plus petite et donc un déplacement plus faible de la tringle.In a simple drive system, where the follower transmits the angular displacement of the stand, it is clear that a decrease in the effective radius of the arm follower causes, for the same angle of rotation, a stroke arm end device smaller and therefore displacement lower of the rod.

Pour augmenter l'amplitude du mouvement de rotation du bras de fouillot, en conservant un angle de déplacement de la béquille limité par le cahier des charges, des mécanismes d'amplification de la rotation faisant intervenir des pignons ont été prévus. De tels mécanismes sont coûteux et prennent de la place.To increase the amplitude of the rotational movement of the follower arm, keeping an angle of movement of the stand limited by the specifications, mechanisms for amplifying the rotation involving gears have been provided. Such mechanisms are expensive and take up space.

On connaít par le document DE 33 42 191 un mécanisme de commande de tringle pour fenêtres, portes ou similaires, du genre défini en préambule, dans lequel le bras de fouillot est réalisé sous la forme d'une roue partiellement dentée, qui entoure le fouillot et est décentrée par rapport à celui-ci. Le fouillot comporte, à titre de moyen d'entraínement du bras de fouillot, un doigt qui fait radialement saillie sur la périphérie du fouillot et qui est logé dans un évidement formé dans le contour intérieur du moyeu de la roue dentée constituant le bras de fouillot. Ceci permet d'augmenter la longueur active du bras de fouillot et par conséquent d'obtenir un déplacement relativement grand de la tringle malgré une entrée de serrure petite. Toutefois, dans ce mécanisme connu, le doigt radial d'entraínement porté par le fouillot est constamment en prise avec les deux côtés de l'évidement du moyeu de la roue dentée. Il en résulte que tout mouvement de rotation du fouillot dans un sens ou dans l'autre entraíne obligatoirement un mouvement de rotation du bras de fouillot dans un sens correspondant autour de son axe de rotation. Ce mécanisme connu ne peut donc pas être utilisé dans une serrure avec pêne demi-tour, dans laquelle il est usuellement souhaité que le fouillot puisse tourner dans une plage de rotation limitée sous l'action de la poignée pour commander l'effacement du pêne demi-tour, sans entraíner en même temps une rotation du bras de fouillot qui est couplé à la tringle portant les organes de verrouillage, donc sans entraíner en même temps un déplacement de la tringle.Document DE 33 42 191 discloses a mechanism for rod control for windows, doors or the like, of the defined kind in the preamble, in which the follower arm is made in the form a partially toothed wheel, which surrounds the follower and is off-center relative to this one. The follower includes, as a means drive arm of the follower, a finger which protrudes radially on the periphery of the follower and which is housed in a formed recess in the inner contour of the hub of the toothed wheel constituting the arm of follower. This increases the active length of the follower and therefore to obtain a relatively large displacement of the rod despite a small lock entry. However, in this known mechanism, the radial drive finger carried by the follower is constantly engaged with both sides of the hub recess of the gear wheel. It follows that any rotational movement of the follower in one direction or the other necessarily involves a movement of rotation of the follower arm in a corresponding direction around its rotation axis. This known mechanism cannot therefore be used in a lock with a latch bolt, in which it is usually wanted the follower to be able to rotate within a limited range of rotation under the action of the handle to control the erasure of the latch bolt, without causing at the same time a rotation of the follower arm which is coupled to the rod carrying the locking members, therefore without cause at the same time a displacement of the rod.

On connaít par ailleurs, par le document FR 2 641 312, un mécanisme de commande pour portes tournantes-basculantes, dans lequel le bras de fouillot est réalisé sous la forme d'une roue partiellement dentée qui entoure concentriquement le fouillot et qui est en prise avec une crémaillère accouplée à des tringles appelées tiges de poussée. Le fouillot ou un disque relié au fouillot comporte, à titre de moyen d'entraínement du bras de fouillot, un doigt qui est engagé dans une cavité plus large que ledit doigt, formée dans le contour intérieur du moyeu de la roue dentée constituant le bras de fouillot. Le disque porte en outre deux cames aptes à agir sur un levier coudé pour commander l'effacement d'un pêne demi-tour de la serrure. Ainsi, grâce au fait que la cavité a une largeur plus grande que celle du doigt d'entraínement, le fouillot et le disque relié à celui-ci peuvent effectuer une rotation limitée, dans les limites permises par la cavité, pour commander l'effacement du pêne demi-tour sans provoquer en même temps une rotation de la roue dentée, donc sans provoquer un déplacement des tringles ou tiges de poussée.We also know, from document FR 2 641 312, a control mechanism for revolving-tilting doors, in which the follower arm is made in the form of a wheel partially toothed which concentrically surrounds the follower and which is in engagement with a rack coupled to rods called rods of thrust. The follower or a disc connected to the follower comprises, as drive means of the follower arm, a finger which is engaged in a cavity wider than said finger, formed in the inner contour of the gear wheel hub constituting the follower arm. The disc carries in addition two cams capable of acting on a bent lever to control the erasure of a latch bolt. So thanks to the fact that the cavity has a width greater than that of the drive finger, the follower and the disc connected to it can rotate limited, within the limits allowed by the cavity, to order erasing the latch bolt without simultaneously causing a rotation of the toothed wheel, therefore without causing displacement of the push rods or rods.

Toutefois, dans cette serrure connue, les éléments sont agencés de telle manière qu'une rotation du fouillot d'un premier angle provoque d'abord l'effacement du pêne demi-tour et une rotation supplémentaire du fouillot d'un second angle, dans le même sens de rotation, provoque ensuite l'amenée des tiges de poussée dans la position de verrouillage, puis le rappel du pêne demi-tour dans sa position de fermeture. Il en résulte que si un utilisateur désirant ouvrir la porte fait tourner le fouillot d'un angle supérieur au premier angle, mais inférieur à la somme des premier et second angles, les pênes haut et bas respectivement associés aux tiges de poussée s'engageront partiellement dans les gâches haute et basse correspondantes et gèneront ou empêcheront l'ouverture de la porte. En outre, si un utilisateur désire verrouiller la porte en faisant tourner le fouillot d'un angle égal à la somme des premier et second angles, il peut arriver que, pendant la rotation du fouillot correspondant au premier angle provoquant l'effacement du pêne demi-tour, la porte soit soumise à une forte poussée extérieure, due par exemple au vent, provoquant une ouverture partielle de la porte. Dans ces conditions, les pênes haut et bas ne seront plus en face des gâches haute et basse et ne pourront pas s'engager dans celles-ci lors de la rotation supplémentaire du fouillot correspondant au second angle.However, in this known lock, the elements are arranged in such a way that rotation of the follower by a first angle first causes the bolt to clear and a rotation additional follower from a second angle, in the same direction of rotation, then causes the push rods to be brought into the position lock, then return the latch bolt to its position closing. As a result, if a user wishing to open the door does rotate the follower by an angle greater than the first angle, but less than the sum of the first and second angles, the top and bottom bolts respectively associated with the push rods will partially engage in the corresponding high and low strikes and will cause or will prevent the door from opening. In addition, if a user wishes lock the door by turning the follower at an angle equal to the sum of the first and second angles, it may happen that during the rotation of the follower corresponding to the first angle causing clearing the latch bolt, the door is subjected to a strong push external, for example due to wind, causing partial opening Door. Under these conditions, the top and bottom bolts will no longer be face of the high and low strikes and will not be able to engage in them during the additional rotation of the follower corresponding to the second angle.

L'invention a pour but de fournir un dispositif de fermeture, notamment une serrure, du genre défini précédemment qui permette, lorsque l'entrée de serrure est petite, d'obtenir néanmoins, en bout de bras de fouillot, un déplacement suffisant pour assurer un coulissement convenable de la tringle. Ce système doit rester d'une construction simple et économique avec un minimum de pièces.The object of the invention is to provide a closure device, in particular a lock, of the kind defined above which allows, when the lock entry is small, obtain nevertheless, at the end of follower arm, sufficient movement to ensure sliding suitable for the rod. This system must remain of a construction simple and economical with a minimum of parts.

Selon l'invention, un dispositif de fermeture, notamment une serrure, du genre défini précédemment est caractérisé par le fait que le doigt est situé radialement à l'extérieur du contour du moyeu du bras de fouillot et l'évidement est formé dans le contour extérieur du moyeu, de telle manière que le doigt entraíne le bras de fouillot pour le sens de rotation convenable, en coopérant avec une butée d'extrémité de l'évidement, et se déplace librement dans cet évidement, sans entraíner le bras de fouillot, pour le déplacement en sens inverse de la poignée ou béquille.According to the invention, a closure device, in particular a lock of the kind defined above is characterized in that the finger is located radially outside the contour of the hub of the arm follower and the recess is formed in the outer contour of the hub, in such a way that the finger drives the follower arm for the direction of suitable rotation, cooperating with an end stop of the recess, and moves freely in this recess, without causing the follower arm, for moving the handle in the opposite direction, or crutch.

La longueur active du bras de fouillot est ainsi augmentée ce qui permet malgré une entrée de serrure petite, d'obtenir un déplacement suffisant en bout de bras de fouillot, avec un minimum de pièces.The active length of the follower arm is thus increased which allows, despite a small lock entry, to obtain a sufficient displacement at the end of the follower arm, with a minimum of rooms.

Il est à noter que plus le doigt est rapproché de l'axe du fouillot, plus la course de la tringle est importante, étant donné que l'axe du fouillot est compris entre le doigt et la tringle.It should be noted that the closer the finger is to the axis of the follower, the greater the travel of the rod, given that the axis of the follower is between the finger and the rod.

De préférence une grande face du boítier de serrure comporte un manchon, d'axe orthogonal au plan de la face, définissant au moins deux portées décentrées assurant respectivement le guidage en rotation du fouillot et du moyeu de bras de fouillot autour de leurs centres de rotation différents.Preferably a large face of the lock case comprises a sleeve, of axis orthogonal to the plane of the face, defining at least two decentered scopes respectively guiding in rotation of the follower and the follower arm hub around their different centers of rotation.

Ce manchon peut comporter un alésage dont l'axe passe par le centre de rotation de fouillot et une surface extérieure constituée sensiblement par deux demi-cylindres de diamètres différents, mais d'axe géométrique commun passant par le centre de rotation décalé du bras de fouillot, les deux demi-cylindres se raccordant par deux épaulements orientés sensiblement radialement.This sleeve may include a bore whose axis passes by the follower center of rotation and an external surface constituted substantially by two half-cylinders of different diameters, but of common geometric axis passing through the offset center of rotation of the follower arm, the two half-cylinders connecting by two shoulders oriented substantially radially.

Le bras de fouillot comporte, au niveau de son moyeu, une ouverture sensiblement semi-circulaire, de même rayon que celui de la grande surface cylindrique du manchon, les extrémités de l'ouverture du moyeu de bras de fouillot étant reliées par une traverse incurvée définissant un arc concave intérieur de plus petit rayon, épousant la surface semi-cylindrique de plus petit rayon du manchon; un épaulement est formé à chaque extrémité de la traverse incurvée pour venir en butée contre un épaulement conjugué du manchon.The follower arm has, at its hub, a substantially semicircular opening, of the same radius as that of the large cylindrical surface of the sleeve, the ends of the opening of the follower arm hub being connected by a curved cross member defining an inner concave arc of smaller radius, matching the semi-cylindrical surface of smaller radius of the sleeve; a shoulder is formed at each end of the curved cross member to come into abutment against a conjugate shoulder of the sleeve.

Le fouillot présente un contour cylindrique circulaire logé dans le manchon et une branche radiale déportée par rapport au plan moyen du fouillot de manière à enjamber la traverse du moyeu de fouillot pour que le doigt puisse entrer dans l'évidement.The follower has a circular cylindrical contour housed in the sleeve and a radial branch offset from the plane means of the follower so as to step over the crosspiece of the hub follower so that the finger can enter the recess.

Avantageusement, le boítier, notamment le palâtre est réalisé en matière plastique ; le manchon formé de deux parties de surfaces cylindriques de diamètres différents vient de moulage avec le boítier.Advantageously, the case, in particular the plaster is made of plastic; the sleeve formed of two parts of cylindrical surfaces of different diameters comes from molding with the housing.

De préférence le centre de rotation du fouillot et le centre de rotation du bras sont situés sur une droite orthogonale à la tringle. Preferably the center of rotation of the follower and the center of arm rotation are located on a line orthogonal to the rod.

Le dispositif de fermeture, notamment la serrure, comporte en général un pêne de condamnation de tringle dont les déplacements sont commandés, par exemple, par un panneton d'un cylindre de sécurité, actionné par une clé autorisée.The closing device, in particular the lock, comprises generally a rod lock bolt whose displacements are controlled, for example, by a bit of a cylinder of security, activated by an authorized key.

Avantageusement, le dispositif de fermeture ou la serrure comporte un moyen d'indexation solidaire du boítier propre à coopérer avec un moyen conjugué prévu sur le pêne. Ceci permet d'éviter que le pêne bouge en dehors des manoeuvres imposées par le panneton. Le moyen d'indexation du boítier peut être constitué par un pion, solidaire du boítier, engagé dans une fenêtre prévue dans le pêne, cette fenêtre comportant un bossage médian définissant, de part et d'autre, deux logements pour le pion, correspondant à deux positions indexées.Advantageously, the closing device or the lock includes an indexing means integral with the housing suitable for cooperating with a combined means provided on the bolt. This will prevent the bolt moves outside the maneuvers imposed by the bit. The indexing means of the housing can be constituted by a pin, integral of the case, engaged in a window provided in the bolt, this window comprising a median boss defining, on either side, two housings for the pin, corresponding to two indexed positions.

Le dispositif de fermeture ou la serrure peut comporter un frein de tringle s'appuyant contre un bossage de la tringle. Le frein de tringle peut être constitué par un moyen élastique, en particulier une languette, solidaire du boítier et venant de moulage avec ce boítier lorsque ce dernier est réalisé en matière plastique. Ce frein de tringle joue un rôle d'anti-vibration pour la tringle et permet, en outre, une indexation de la position de tringle.The closure device or the lock may include a rod brake pressing against a rod boss. The brake rod can be constituted by an elastic means, in particular a tongue, integral with the housing and coming from molding with this housing when the latter is made of plastic. This rod brake plays a role of anti-vibration for the rod and allows, in addition, a rod position indexing.

L'invention sera exposée ci-après à propos d'exemples de réalisation décrits en se référant au dessin annexé, mais qui ne sont nullement limitatifs.The invention will be exposed below about examples of implementation described with reference to the accompanying drawing, but which are in no way limiting.

La description qui suit concerne une serrure mais s'applique à tout dispositif de fermeture ayant une structure semblable , en particulier une crémone de fenêtre.The following description relates to a lock but applies to any closure device with a similar structure, in particular a window lever.

En se reportant aux dessins, notamment à la figure 3, on peut voir une serrure 1 à encastrer dans un battant de porte ou de porte-fenêtre.Referring to the drawings, in particular to FIG. 3, we can see a lock 1 to be embedded in a door or window door leaf.

La serrure comporte un boítier plat 2 constitué d'un palâtre 3 fermé, sur une grande face, par un foncet 4 (fig.4).The lock has a flat case 2 made of a plaster 3 closed, on a large side, with a wall 4 (fig.4).

La serrure est destinée, notamment, à la manoeuvre d'une tringle 5 montée coulissante sur le chant du battant de porte (non représenté), qui est situé dans un plan vertical orthogonal au plan de la figure 3.The lock is intended, in particular, for the operation of a rod 5 sliding mounted on the edge of the door leaf (not shown), which is located in a vertical plane orthogonal to the plane of the figure 3.

La tringle 5 comprend une partie basse 5a, qui est abaissée pour le verrouillage, et une partie haute 5b qui est soulevée pour le verrouillage. Des organes de verrouillage, tels que des rouleaux (non représentés) sont prévus sur la tringle 5.The rod 5 comprises a lower part 5a, which is lowered for locking, and a high part 5b which is raised for the locking. Locking devices, such as rollers (not shown) are provided on the rod 5.

Un pêne demi-tour 6 est monté dans le boítier 2, coulissant perpendiculairement à la direction de la tringle 5, c'est-à-dire horizontalement. Le pêne demi-tour 6 comporte une tête prismatique 7 avec une face oblique 7a et une face 7b parallèle à la grande face du palâtre. Les faces horizontales supérieures et inférieures de la tête 7 comportent des rainures de guidage sensiblement semi-cylindriques 7c s'étendant parallèlement à la grande face du palâtre. Le pêne 6 traverse une ouverture pratiquée dans une plaque 8, ou têtière, fixée contre le chant de porte et fixée au boítier 1. L'ouverture dans la têtière 8 comporte un empennage 8a s'engageant dans les rainures 7c. La tringle 5 coulisse contre la face intérieure de la têtière 8.A latch bolt 6 is mounted in the housing 2, sliding perpendicular to the direction of the rod 5, i.e. horizontally. The latch bolt 6 has a prismatic head 7 with an oblique face 7a and a face 7b parallel to the large face of the lock box. The upper and lower horizontal faces of the head 7 have substantially semi-cylindrical guide grooves 7c extending parallel to the large face of the plaster. Bolt 6 crosses an opening in a plate 8, or headrest, fixed against the door edge and fixed to the housing 1. The opening in the headrest 8 comprises a tail unit 8a engaging in the grooves 7c. The rod 5 slides against the inner face of the headrest 8.

La tête 7 du pêne est solidaire d'une tige ou queue de pêne 9 s'étendant horizontalement dans le boítier et munie, à son extrémité intérieure, d'un embout 10, ou pièce d'entraínement du pêne, s'étendant perpendiculairement au plan de la figure 3. L'embout 10 est constitué par une plaquette obtenue à partir d'un disque circulaire coupé suivant deux méplats parallèles symétriques par rapport au centre et dont les extrémités sont raccordées par des arcs de cercle. L'embout 10 est guidé en translation par la paroi intérieure d'un logement 11 (fig.8) dans lequel est monté un ressort de compression 12 poussant le pêne demi-tour 6 vers l'extérieur. L'extrémité du logement 11 située du côté de la tête 7 comporte un évidement 11a de diamètre suffisant pour permettre la rotation de l'embout 10 autour de l'axe géométrique de la tige 9.The bolt head 7 is integral with a bolt rod or tail 9 extending horizontally in the housing and provided at its end interior, a tip 10, or piece of bolt drive, extending perpendicular to the plane of Figure 3. The tip 10 is consisting of a plate obtained from a circular disc cut along two parallel flats symmetrical with respect to the center and whose ends are connected by arcs of a circle. The end piece 10 is guided in translation by the inner wall of a housing 11 (fig. 8) in which a compression spring 12 is mounted pushing the latch bolt 6 outwards. The end of the housing 11 located on the side of the head 7 has a recess 11a in diameter sufficient to allow rotation of the nozzle 10 around the axis rod geometry 9.

L'embout 10 est en prise avec une pièce 13 de commande du pêne demi-tour dont il sera question plus loin.The end piece 10 is engaged with a control part 13 of the latch bolt which will be discussed later.

Un fouillot 14 est monté rotatif, dans le boítier 2, autour d'un axe géométrique orthogonal au plan moyen du boítier, c'est-à-dire perpendiculaire au plan des figures 1, 2 et 3 des dessins. Le fouillot 14 comporte un trou 15 carré pour être traversé par une tige d'entraínement de section transversale conjuguée commandée par une béquille 16. Un ressort de torsion 14r exerce un rappel élastique sur le fouillot. A follower 14 is rotatably mounted, in the housing 2, around of a geometric axis orthogonal to the mean plane of the housing, that is to say perpendicular to the plane of Figures 1, 2 and 3 of the drawings. The follower 14 has a square hole 15 to be crossed by a rod drive of combined cross section controlled by a stand 16. A torsion spring 14r exerts an elastic return on the follower.

La béquille 16 peut exécuter, à partir de la position de repos, un mouvement dans un premier sens, en particulier un mouvement d'abaissement, pour commander le retrait du pêne demi-tour 6 dans le boítier 1, par un mécanisme d'entraínement classique qui ne sera pas décrit plus en détail. La béquille 16 peut aussi exécuter un mouvement dans le sens opposé, c'est-à-dire un mouvement de soulèvement comme illustré sur la figure 2, pour entraíner en rotation le fouillot 14 et commander le déplacement de la tringle 5 par l'intermédiaire d'un bras de fouillot 17.The stand 16 can execute, from the position of rest, a movement in the first direction, especially a lowering movement, to control the withdrawal of the latch bolt 6 in the housing 1, by a conventional drive mechanism which will not be described in more detail. The stand 16 can also execute a movement in the opposite direction, i.e. a movement of lifting as illustrated in Figure 2, to drive in rotation the follower 14 and control the displacement of the rod 5 by through a follower arm 17.

Comme visible sur les figures 1 et 2, le bras de fouillot 17 comporte un moyeu 18 entourant le fouillot 14 et, à son extrémité éloignée du centre de rotation, des dents 19 propres à s'engager dans des ouvertures correspondantes 20, prévues dans la partie basse 5a de la tringle 5. Ces dents 19 permettent d'entraíner directement la partie basse 5a en coulissement vertical en réponse à un mouvement de rotation du bras de fouillot 17.As seen in Figures 1 and 2, the follower arm 17 has a hub 18 surrounding the follower 14 and, at its end distant from the center of rotation, teeth 19 suitable for engaging in corresponding openings 20, provided in the lower part 5a of the rod 5. These teeth 19 allow to directly drive the part bass 5a in vertical sliding in response to a movement of rotation of the follower arm 17.

D'autres dents 19b sont prévues sur le moyeu 18 pour engrener avec un secteur denté 19c articulé sur un axe solidaire du palâtre. Le secteur 19c commande le déplacement de la partie haute 5b de la tringle, en sens inverse de la partie basse 5a.Other teeth 19b are provided on the hub 18 for mesh with a toothed sector 19c articulated on an axis integral with the lock box. The sector 19c controls the movement of the upper part 5b of the rod, in the opposite direction from the lower part 5a.

L'amplitude du déplacement vertical de la tringle basse 5a, en réponse à un mouvement de rotation du bras de fouillot 17 d'amplitude angulaire déterminée, dépend du rayon efficace du bras de fouillot 17, c'est-à-dire de la distance entre le centre de rotation de ce bras et les dents 19.The amplitude of the vertical displacement of the lower rod 5a, in response to a rotational movement of the follower arm 17 of determined angular amplitude, depends on the effective radius of the arm follower 17, i.e. the distance between the center of rotation of this arms and teeth 19.

Le fouillot 14 tourne autour d'un axe géométrique coupant le plan de la figure 1 au point A. La distance E entre ce point A et la face extérieure de la têtière 8 est l'"entrée de serrure" et correspond à la distance entre le trou pratiqué dans la porte pour le passage de la tige carrée d'entraínement du fouillot 14, et le chant de porte.The follower 14 rotates around a cutting geometric axis the plane of Figure 1 at point A. The distance E between this point A and the outer face of the headrest 8 is the "lock entry" and corresponds to the distance between the hole made in the door for the passage of the rod square drive of the follower 14, and the door edge.

On souhaite que cette distance E soit petite.We want this distance E to be small.

Pour éviter que cette petite distance E n'entraíne une réduction sensible de la longueur du rayon efficace du bras de fouillot 17, ce qui entraínerait un déplacement vertical insuffisant de la tringle basse 5a, l'invention prévoit la disposition exposée ci-après. To prevent this small distance E from causing a appreciable reduction in the effective radius length of the follower arm 17, which would cause insufficient vertical displacement of the rod low 5a, the invention provides the arrangement set out below.

Comme illustré sur les figures 1 et 2, le bras de fouillot 17 est décentré relativement au fouillot 14 de manière tourner autour d'un point B plus éloigné de la tringle 5 que le centre de rotation A du fouillot, lequel comporte un moyen 21 pour entraíner directement en rotation le bras de fouillot 17, sans pièce intermédiaire telle qu'un ou plusieurs pignons. La distance de B à la tringle 5 est égale à E + Y.As illustrated in Figures 1 and 2, the follower arm 17 is off-center relative to the follower 14 so as to turn around from a point B further from the rod 5 than the center of rotation A of the follower, which includes a means 21 for directly driving rotation of the follower arm 17, without intermediate part such as one or several gables. The distance from B to the rod 5 is equal to E + Y.

Le moyen 21 est constitué par un doigt 22 solidaire d'une branche radiale 23 liée au fouillot 14 dont elle est solidaire. Le doigt 22 est situé radialement à l'extérieur du contour du moyeu 18 de bras de fouillot et est logé dans un évidement 24 de ce moyeu 18. Le doigt 22 peut entraíner le bras de fouillot 17 pour le sens de rotation convenable de béquille, à savoir le sens contraire d'horloge selon le schéma des figures 1 et 2, en coopérant avec une butée d'extrémité de l'évidement 24.The means 21 is constituted by a finger 22 integral with a radial branch 23 linked to the follower 14 with which it is integral. Finger 22 is located radially outside the contour of the hub 18 of the follower and is housed in a recess 24 of this hub 18. The finger 22 can drive the follower arm 17 for the proper direction of rotation stand, i.e. the opposite direction of the clock according to the diagram of Figures 1 and 2, cooperating with an end stop of the recess 24.

Pour un déplacement de la béquille 16 depuis la position de repos de la figure 1 dans le sens d'horloge, le doigt 21 se déplace librement dans l'évidement 24 sans entraíner le bras 17.To move the stand 16 from the position rest of Figure 1 clockwise, finger 21 moves freely in the recess 24 without driving the arm 17.

Ce bras 17 comporte, au niveau de son moyeu 18, une ouverture 25 sensiblement semi-circulaire, centrée sur le point B, les extrémités de cette ouverture 25 étant reliées par une traverse incurvée 26 définissant un arc concave intérieur 27, également centré sur le point B, mais de plus petit rayon que la majeure partie de l'ouverture 25. La branche radiale 23 du fouillot est déportée pour enjamber la traverse 26, afin que le doigt 22 entre dans l'évidement 24.This arm 17 has, at its hub 18, a opening 25 substantially semi-circular, centered on point B, the ends of this opening 25 being connected by a curved crosspiece 26 defining an inner concave arc 27, also centered on the point B, but with a smaller radius than most of the opening 25. The radial branch 23 of the follower is offset to span the cross 26, so that the finger 22 enters the recess 24.

La grande face du boítier 2 constituée par le fond du palâtre 3 opposé au foncet 4 comporte un manchon 28 d'axe orthogonal au plan de la face, c'est-à-dire orthogonal au plan des figures 1 et 2. Ce manchon 28 définit, par sa surface extérieure, deux portées 29, 30 constituées par des arcs de cercle, de rayon différent, centrés sur le point B. La portée 29 a un rayon égal à celui de l'ouverture 25 et épouse la surface circulaire intérieure de cette ouverture, tandis que la portée 30 a un rayon plus petit égal à celui de l'arc concave 27. Les deux extrémités de la portée 30 se raccordent aux extrémités de la portée 29 par des épaulements 31 à orientation radiale, constituant des butées fin de course propres à coopérer avec les extrémités respectives de la traverse 26. L'étendue angulaire de la portée 29 est inférieure à celle de l'ouverture 25 de sorte que dans la position de repos de la béquille 16, illustrée sur la figure 1, un espace libre angulaire I existe entre l'épaulement 31 supérieur et l'extrémité supérieure de la traverse 26. Cet espace angulaire correspond à la course autorisée vers le haut de la béquille 16, d'environ 45° comme illustré sur la figure 2.The large face of the housing 2 formed by the bottom of the palâtre 3 opposite the foncet 4 has a sleeve 28 of orthogonal axis in the plane of the face, that is to say orthogonal to the plane of FIGS. 1 and 2. This sleeve 28 defines, by its outer surface, two bearing surfaces 29, 30 formed by arcs of a circle, of different radius, centered on the point B. The bearing 29 has a radius equal to that of the opening 25 and marries the inner circular surface of this opening, while the range 30 has a smaller radius equal to that of the concave arc 27. The two ends of the span 30 are connected to the ends of the carried 29 by shoulders 31 in radial orientation, constituting limit switches suitable for cooperating with the respective ends of the cross member 26. The angular extent of the span 29 is less than that of the opening 25 so that in the rest position of the stand 16, illustrated in FIG. 1, an angular free space I exists between the upper shoulder 31 and the upper end of the cross-member 26. This angular space corresponds to the authorized upward stroke stand 16, about 45 ° as illustrated in Figure 2.

Lorsque le palâtre 3 est réalisé en matière plastique, le manchon 28 est avantageusement d'une seule pièce avec le palâtre 3 et vient de moulage avec lui.When the plaster 3 is made of plastic, the sleeve 28 is advantageously in one piece with the plaster 3 and just molding with him.

Le manchon 28 comporte une ouverture centrale cylindrique 32 de section circulaire, dont le centre correspond au point A. Le fouillot 14 présente un contour extérieur cylindrique circulaire de même rayon que l'ouverture 32 dans laquelle il est logé et guidé en rotation autour du point A.The sleeve 28 has a central opening cylindrical 32 of circular section, the center of which corresponds to the point A. The follower 14 has a circular cylindrical outer contour of the same radius as the opening 32 in which it is housed and guided in rotation around point A.

De préférence le centre de rotation A du fouillot 14 et le centre de rotation B du bras de fouillot 17 sont situés sur une droite orthogonale à la tringle 5.Preferably the center of rotation A of the follower 14 and the center of rotation B of the follower arm 17 are located on a straight line orthogonal to the rod 5.

Ceci étant, le fonctionnement de la serrure en ce qui concerne la commande de la tringle 5 par la béquille 16 et le bras de fouillot 17 est le suivant.That said, the operation of the lock with respect to relates to the control of the rod 5 by the stand 16 and the arm of follower 17 is as follows.

Dans la position de repos de la béquille 16, illustrée sur la figure 1, le doigt 21 se trouve au voisinage de l'extrémité supérieure de l'évidement 24, et l'espace libre I est situé entre l'épaulement radial supérieur 31 et l'extrémité supérieure de la traverse 26. L'extrémité inférieure de cette traverse 26 est en butée contre l'épaulement radial 31 inférieur.In the rest position of the stand 16, illustrated on the Figure 1, the finger 21 is located near the upper end of the recess 24, and the free space I is located between the radial shoulder upper 31 and the upper end of the crosspiece 26. The end lower of this cross 26 is in abutment against the radial shoulder 31 lower.

Si la béquille 16 est abaissée, le doigt 21 se déplace librement dans l'évidement 24, sans entraíner le bras de fouillot 17 qui reste dans la position illustrée sur la figure 1. Ce mouvement de descente de la béquille 16 est utilisé, de manière classique, pour commander le retrait du pêne demi-tour 6.If the stand 16 is lowered, the finger 21 moves freely in the recess 24, without driving the follower arm 17 which remains in the position illustrated in FIG. 1. This movement of lowering the stand 16 is conventionally used to order the withdrawal of the latch bolt 6.

Lorsque la béquille 16 est soulevée, comme illustré sur la figure 2, le fouillot 14 et le doigt 21 tournent dans le sens contraire d'horloge et le doigt 21 en butant contre l'extrémité supérieure de l'évidement 24 entraíne en rotation le bras de fouillot 17.When the stand 16 is raised, as illustrated on the Figure 2, the follower 14 and the finger 21 rotate in the opposite direction clock and finger 21 abutting against the upper end of the recess 24 rotates the follower arm 17.

Alors que la rotation du fouillot 14 s'effectue autour du centre A distant seulement de E du chant de porte, la rotation du bras de fouillot 17 s'effectue autour du centre B distant de E + Y du chant de porte.While the rotation of the follower 14 takes place around the center A distant only from E of the door edge, the rotation of the arm of follower 17 takes place around center B distant from E + Y of the song door.

Le rayon efficace du bras 17, déterminant l'amplitude du déplacement périphérique des dents 19 pour un angle donné, est donc supérieur à E. Il en résulte un déplacement linéaire plus important de la tringle 5 dans sa partie basse Sa. En fin de déplacement, comme visible sur la figure 2, la dent 19 du bras 17 qui coopère avec l'ouverture 20 de la tringle 5 n'est plus la même que celle de la position de départ.The effective radius of the arm 17, determining the amplitude of the peripheral displacement of teeth 19 for a given angle, is therefore greater than E. This results in a greater linear displacement of the rod 5 in its lower part Sa. At the end of displacement, as visible in FIG. 2, the tooth 19 of the arm 17 which cooperates with the opening 20 of the rod 5 is no longer the same as that of the starting position.

Dans la position de soulèvement maximal de la béquille 16 illustrée sur la figure 2, l'espace libre I s'est déplacé entre l'épaulement radial inférieur 31 et l'extrémité inférieure de la traverse 26. L'extrémité supérieure de la traverse 26 est en butée contre l'épaulement radial supérieur 31.In the stand-up position 16 illustrated in FIG. 2, the free space I has moved between the shoulder lower radial 31 and the lower end of the cross member 26. The upper end of the cross member 26 abuts against the upper radial shoulder 31.

Lorsqu'on abaisse la béquille 16 à partir de la position de la figure 2, le doigt 21 se déplace librement dans l'évidement 24 sans entraíner le bras 17 ni la tringle 5.When lowering the stand 16 from the position Figure 2, the finger 21 moves freely in the recess 24 without train the arm 17 or the rod 5.

Quand la béquille 16 retrouve la position de repos de la figure 1, le doigt 21 se trouve alors en butée contre l'extrémité inférieure de l'évidement 24.When the stand 16 returns to the rest position of the Figure 1, the finger 21 is then in abutment against the end lower of the recess 24.

Si, à partir de cette position non représentée sur les dessins, on abaisse la béquille 16, on commande alors le déplacement de la tringle 5 pour la ramener dans la position de repos de la figure 1, simultanément au retrait du pêne demi-tour 6.If, from this position not shown on the drawings, lower the stand 16, then control the movement the rod 5 to bring it back to the rest position of FIG. 1, simultaneously with the withdrawal of the latch 6.

La solution de l'invention permet une démultiplication du mouvement d'ouverture ou de fermeture de la serrure avec un mécanisme compact et un minimum de pièces, en entraínant directement le bras de fouillot 17 par le fouillot 14, sans pièce intermédiaire telle qu'un ou des pignons.The solution of the invention allows a reduction of the opening or closing movement of the lock with a compact mechanism and a minimum of parts, training directly the follower arm 17 by the follower 14, without parts intermediate such as one or more pinions.

Ce mécanisme compact peut être intégré à plusieurs modèles de serrure variant par leur entrée E. En outre le manchon 28 constitue une pièce support qui assure un guidage correct en rotation du fouillot 14 et du bras de fouillot 17. Ce mécanisme conçu sur une base d'encombrement minimal peut avantageusement être transplanté dans tout autre boítier de taille supérieure.This compact mechanism can be integrated into several lock models varying by their entry E. In addition the sleeve 28 constitutes a support piece which ensures correct guiding in rotation of the follower 14 and of the follower arm 17. This mechanism designed on a base advantageously can be transplanted into any other larger case.

On considère maintenant le problème de montage posé par le pêne demi-tour 6 à face oblique 7a qui doit être toujours celle venant en contact avec la partie fixe de la serrure, située sur le montant de la porte, au moment de la fermeture. Comme il existe des portes ouvrant à droite ou à gauche, en tirant ou en poussant, les serrures doivent être adaptées à tous les besoins.We now consider the mounting problem posed by the oblique face latch 6a 7a which must always be the one coming in contact with the fixed part of the lock, located on the upright of the door, at the time of closing. As there are doors opening on the right or on the left, by pulling or pushing, the locks must be adapted to all needs.

Dans ce but, l'invention vise à procurer une serrure qui permet, de manière simple et rapide, de retourner le pêne de 180°.For this purpose, the invention aims to provide a lock which allows you to quickly and easily turn the latch 180 °.

Comme visible sur la figure 3, la pièce de commande 13 du pêne est constituée par un bras sensiblement vertical articulé, vers son extrémité supérieure, sur un axe 33 avantageusement réalisé en matière plastique et venu de moulage avec le palâtre 3. Le bras 13 s'étend vers le bas au-delà de la queue de pêne 9 et comporte une lumière 34 dans laquelle vient s'engager une extrémité de l'embout 10. Les bords horizontaux supérieurs et inférieurs de la lumière ou fenêtre 34, comme visible sur la figure 9, comportent un chanfrein c pour faciliter le désengagement et le réengagement, par rotation autour de l'axe géométrique de la queue de pêne 9, de l'embout 10 dont les petits côtés sont arrondis. Les bords v de la lumière 34 orthogonaux à l'axe géométrique de la queue de pêne 9 ne comportent pas de chanfrein prononcé pour éviter tout désengagement de l'embout d'entraínement 10 en réponse à un mouvement de translation du pêne parallèle à l'axe géométrique de la queue de pêne 9.As shown in Figure 3, the control piece 13 of the bolt is constituted by a substantially vertical articulated arm, towards its upper end, on an axis 33 advantageously made in plastic and molded material with the plaster 3. The arm 13 extends downward beyond the bolt 9 and has a light 34 in which engages one end of the endpiece 10. The upper and lower horizontal edges of the light or window 34, as visible in FIG. 9, have a chamfer c for facilitate disengagement and re-engagement, by rotation around the geometric axis of the bolt tail 9, of the end piece 10, the small sides are rounded. The edges v of the light 34 orthogonal to the axis bolt tail geometry 9 does not have a chamfer pronounced to avoid any disengagement of the drive end 10 in response to a translational movement of the bolt parallel to the axis bolt tail geometry 9.

La serrure comprend un moyen de butée R pour la pièce de commande 13 en position de repos, ce moyen de butée étant propre à être effacé de l'extérieur du boítier.The lock comprises a stop means R for the part 13 in the rest position, this stop means being clean to be erased from the outside of the case.

Le moyen de butée R est constitué par une patte 35 liée au boítier 2, et sur laquelle il est possible d'agir avec un outil T de l'extérieur du boítier par au moins une ouverture 36 prévue dans une paroi du boítier, en particulier prévue dans le foncet 4.The stop means R consists of a tab 35 linked to the box 2, and on which it is possible to act with a tool T of the outside of the housing by at least one opening 36 provided in a wall of the housing, in particular provided in the wall 4.

Plus précisément, dans le cas d'un palâtre 3 réalisé en matière plastique, la patte 35 est elle-même réalisée en matière plastique et vient de moulage avec le palâtre. La patte 35 est contre-coudée et solidaire du palâtre ; elle comporte à son extrémité libre un bossage 35a accessible à travers l'ouverture 36 prévue dans le foncet 4.More specifically, in the case of a plaster 3 produced in plastic material, the lug 35 is itself made of material plastic and comes from molding with the plaster. Leg 35 is angled and integral with the plaster; it has at its free end a boss 35a accessible through the opening 36 provided in the hole 4.

Selon la réalisation des figures 3 et 4, la patte 35 s'étend sensiblement parallèlement à la queue de pêne 9 et comporte un retour à angle droit 37 solidaire du fond du palâtre 3. According to the embodiment of Figures 3 and 4, the tab 35 extends substantially parallel to the bolt tail 9 and has a return at right angles 37 secured to the bottom of the plaster 3.

La patte 35 peut pivoter, par déformation élastique de torsion, autour d'un axe orthogonal à la grande face du palâtre 3, c'est-à-dire un axe orthogonal au plan de la figure 3.The tab 35 can pivot, by elastic deformation of torsion, around an axis orthogonal to the large face of the plaster 3, i.e. an axis orthogonal to the plane of Figure 3.

Le bossage 35a de la patte 35 forme une butée pour un bord de la pièce de commande 13, comme visible sur la figure 3, et retient cette pièce dans la position de repos, le pêne demi-tour 6 étant alors sorti normalement.The boss 35a of the tab 35 forms a stop for a edge of the control part 13, as visible in FIG. 3, and retains this part in the rest position, the latch bolt 6 being so went out normally.

Le bord de la pièce de commande 13 comporte, au dessous de la zone venant normalement en butée contre le bossage 35a, une échancrure 38 dans laquelle peut être engagé le bossage 35a par déplacement de la patte à l'aide de l'outil T (fig.5), ce qui permet la sortie complète du pêne 6, comme illustré sur la Figure 6. La pièce de communde 13 est retenue par le bossage 35a en appui contre le fond de l'échancrure 38.The edge of the control part 13 comprises, below the zone normally coming into abutment against the boss 35a, a notch 38 in which the boss 35a can be engaged by displacement of the tab using tool T (fig. 5), which allows complete removal of the bolt 6, as illustrated in Figure 6. The common part 13 is retained by the boss 35a resting against the bottom of the notch 38.

Dans cette position avancée de la queue de pêne 9, l'embout 10 est sorti du logement 11 du ressort 12 et se trouve au niveau de l' évidement 11a de diamètre plus important permettant la rotation de l'embout 10 autour de l'axe géométrique de la queue de pêne 9.In this advanced position of the bolt tail 9, the end piece 10 is removed from the housing 11 of the spring 12 and is located at level of the recess 11a of larger diameter allowing the rotation of the nozzle 10 around the geometric axis of the tail bolt 9.

Il est alors possible de faire tourner le pêne 6 de 180° autour de l'axe de la queue de pêne 9 en exerçant un couple de rotation sur la tête 7. L'extrémité de l'embout 10, située dans la lumière 34, se dégage de cette lumière en coopérant avec un chanfrein c et l'extrémité opposée de l'embout 10 vient se loger dans la lumière 34 après le demi-tour complet de la tête 7.It is then possible to rotate the bolt 6 by 180 ° around the axis of the bolt tail 9 by exerting a torque on the head 7. The end of the end piece 10, located in the lumen 34, is gives off this light by cooperating with a chamfer c and the end opposite of the end piece 10 is housed in the lumen 34 after the U-turn full head 7.

Lors de la manipulation de retournement, l'embout 10 est dégagé de la lumière 34 et la pièce 13 n'est plus soumise à la poussée du ressort 12 . La pièce 13 pourrait avoir tendance, par son propre poids, à revenir dans la position de la figure 3, auquel cas l'embout 10 ne serait plus en face de la lumière 34 après le demi-tour. Ceci est empêché car la pièce 13 est maintenue en position angulaire du fait de la contrainte de torsion de la patte 35 qui provoque une poussée de la face supérieure du bossage 35a contre le bord supérieur de l'échancrure 38. Le frottement ainsi créé assure la retenue de la pièce 13.During the turning operation, the end piece 10 is cleared from the light 34 and the part 13 is no longer subjected to the thrust spring 12. Exhibit 13 could tend, by its own weight, to return to the position of FIG. 3, in which case the end piece 10 would no longer be in front of light 34 after the U-turn. this is prevented because the part 13 is kept in angular position due to the torsional stress of the lug 35 which causes a push of the upper face of the boss 35a against the upper edge of notch 38. The friction thus created ensures the retention of the part 13.

Après retournement du pêne 6, l'ensemble est remis en place en repoussant le pêne 6 à l'intérieur du boítier 1. La pièce 13, entraínée par l'embout 10, pivote dans le sens contraire d'horloge autour de l'axe 33 et l'échancrure 38 se dégage du bossage 35a. La patte 35 revient, par élasticité, dans sa position normale illustrée sur la figure 3.After turning over the bolt 6, the assembly is returned to place by pushing the bolt 6 inside the housing 1. The part 13, driven by the nozzle 10, pivots in the opposite direction of the clock around the axis 33 and the notch 38 emerges from the boss 35a. The leg 35 returns, by elasticity, to its normal position illustrated on the figure 3.

La réintroduction du profil de tête 7 s'effectue en engageant les rainures 7c dans l'empennage de la têtière 8.The reintroduction of the head profile 7 is carried out in engaging the grooves 7c in the empennage of the headrest 8.

Les explications qui précèdent font apparaítre le fonctionnement de la serrure permettant d'assurer le retournement du pêne demi-tour.The foregoing explanations show the operation of the lock to ensure the reversal of the turn around.

Les figures 10 à 13 montrent une variante de réalisation dans laquelle les éléments identiques ou jouant des rôles analogues sont désignés par les mêmes chiffres de référence éventuellement précédés du chiffre 1 des centaines.Figures 10 to 13 show an alternative embodiment in which identical elements or playing analogous roles are designated by the same reference numbers possibly preceded from the number 1 of hundreds.

Le moyen de butée R est constitué par une patte 135 venue de moulage avec le palâtre 3 en matière plastique. On retrouve le bossage 135a coopérant avec un bord de la pièce 113 pour la retenir en position de repos. Toutefois, le bord de cette pièce 113 ne comporte plus d'échancrure. L'effacement de la patte 135 est réalisé par un mouvement de pivotement autour d'un axe vertical, parallèle à la grande face du palâtre 3, de telle sorte que le bossage 135a passe en arrière de la pièce 113, selon la représentation des dessins, lorsqu'on exerce sur le bossage 135a une poussée à l'aide d'un outil T (fig.13).The stop means R is constituted by a tab 135 coming molding with the plaster 3 plastic. We find the boss 135a cooperating with an edge of the part 113 to retain it in rest position. However, the edge of this piece 113 does not include more indentation. The erasing of the tab 135 is carried out by a pivoting movement about a vertical axis, parallel to the large face of the plaster panel 3, so that the boss 135a passes in rear of room 113, according to the representation of the drawings, when exerts on the boss 135a a thrust using a tool T (fig.13).

Lorsque la pièce 113 a été ainsi libérée de la butée constituée par le bossage 135a, elle exécute un mouvement de rotation supplémentaire, dans le sens d'horloge, assurant la sortie complète de la tête de pêne 7, comme illustré sur la figure 13.When the part 113 has thus been released from the stop constituted by the boss 135a, it performs a rotational movement additional, clockwise, ensuring complete exit from the bolt head 7, as illustrated in FIG. 13.

On peut donc effectuer le mouvement de retournement de la tête 7 par rotation de 180° autour de l'axe de la queue de pêne 9.We can therefore perform the reversal movement of the head 7 by rotation of 180 ° around the axis of the bolt tail 9.

Lorsque l'embout 10 est sorti de la lumière 34, pendant l'opération de retournement, la pièce 113 est retenue en position angulaire par la pression exercée par le bossage 135a contre la face arrière de la pièce 113 (fig.12).When the end piece 10 has come out of the light 34, during the inversion operation, the part 113 is retained in position angular by the pressure exerted by the boss 135a against the face back of part 113 (fig. 12).

Comme précédemment, après retournement du pêne demi-tour, il suffit de réintroduire le profil de la tête 7 dans l'empennage 8a de la têtière et de repousser le pêne pour replacer la serrure dans sa position de repos et procéder à son installation. As before, after turning the latch turn, just reintroduce the profile of the head 7 into the tail 8a of the headrest and push back the bolt to replace the lock in its rest position and proceed with its installation.

Selon l'invention, aucune pièce spécifique n'est nécessaire au retournement du pêne. Il n'y a aucun ressort spécial, aucune vis à démonter ou autre pièce à retirer.According to the invention, no specific part is necessary when turning the bolt. There is no special spring, no screws disassemble or other part to be removed.

Ceci entraíne un gain sensible pour le fabricant au niveau de la réalisation des pièces et du temps d'assemblage. De plus l'opération de retournement est facilitée, sans risque de perte de pièces par l'utilisateur.This results in a significant gain for the manufacturer in terms of the production of parts and the assembly time. Moreover the turning operation is facilitated, without risk of loss of parts by the user.

L'outil T à utiliser est standard et commun, par exemple tournevis, pointe, couteau, ciseaux.The T tool to use is standard and common, for example screwdriver, point, knife, scissors.

La réalisation en matière plastique, par exemple acétal, polyacétal, chargé ou non, du palâtre 3 et des pattes 35, 135 et autres éléments venant directement de moulage, est particulièrement avantageuse.The production of plastic, for example acetal, polyacetal, loaded or not, with plaster 3 and legs 35, 135 and others elements coming directly from molding, is particularly advantageous.

La serrure comporte en partie basse, dans la réalisation envisagée, un pêne dormant 39 pour la condamnation de la tringle 5. Ce pêne 39 peut être déplacé en translation circulaire par un panneton 39a d'un cylindre de sécurité 39b commandé par une clé.The lock has in the lower part, in the embodiment envisaged, a deadbolt 39 for the locking of the rod 5. This bolt 39 can be moved in circular translation by a bit 39a of a safety cylinder 39b controlled by a key.

Le pêne 39 comporte une fenêtre 40 (fig.7) ayant un bossage médian 41 définissant de part et d'autre un logement d'indexation.The bolt 39 has a window 40 (fig. 7) having a median boss 41 defining on both sides a housing indexing.

Un pion 42 solidaire de la grande face du palâtre 3 est prévu pour pénétrer dans cette fenêtre, ce pion présentant une certaine élasticité. De préférence, lorsque le palâtre 3 est réalisé en matière plastique, le pion 42 est également réalisé en matière plastique et vient de moulage avec le palâtre.A pin 42 integral with the large face of the plaster 3 is planned to enter this window, this pawn having a certain elasticity. Preferably, when the plaster 3 is made of material plastic, pin 42 is also made of plastic and comes molding with the plaster.

Le pion 42 se place dans l'un ou l'autre des logements situés de part et d'autre du bossage 41 et franchit ce bossage par déformation élastique lors du mouvement du pêne.Pawn 42 is placed in one or other of the housings located on either side of the boss 41 and crosses this boss by elastic deformation during the movement of the bolt.

Le pion 42 permet de réaliser une indexation de position du pêne, en exerçant un léger effort élastique de pression contre le bord de la fenêtre conjuguée et évite que le pêne bouge en dehors des manoeuvres imposées par le panneton du cylindre de sécurité.Pawn 42 allows for position indexing of the bolt, exerting a slight elastic pressure force against the edge of the combined window and prevents the bolt from moving outside the maneuvers imposed by the safety cylinder bit.

Un frein de tringle 43 est en outre prévu sous la forme d'une languette élastique 44 fixée au palâtre 3. Lorsque ce dernier est réalisé en matière plastique, la languette 44 est également réalisée en matière plastique et vient de moulage avec le palâtre. La languette 44 a une forme de L et présente une branche sensiblement parallèle à la tringle 5 munie à son extrémité supérieure d'un renflement 44a propre à s'appuyer et à frotter contre un bossage 45 de la tringle 5.A rod brake 43 is further provided in the form an elastic tongue 44 fixed to the plaster 3. When the latter is made of plastic, the tongue 44 is also made of plastic material and comes from molding with the plaster. Tab 44a an L shape and has a branch substantially parallel to the rod 5 provided at its upper end with a clean bulge 44a to lean against and rub against a boss 45 on the rod 5.

Le frein de tringle 43 a un rôle d'anti-vibration pour la tringle 5. Il permet par ailleurs une indexation de la position de la tringle 5, par exemple par coopération du renflement 44a avec un léger creux prévu dans le bossage 45.The rod brake 43 has an anti-vibration role for the rod 5. It also allows indexing of the position of the rod 5, for example by cooperation of the bulge 44a with a slight hollow provided in boss 45.
