Description

DISPOSITIF D'ACCOUPLEMENT DE DEUX DEMI-CYLINDRES  DEVICE FOR COUPLING TWO HALF CYLINDERS
La présente invention concerne le domaine de la serrurerie et plus précisément les ensembles de serrurerie comportant des cylindres à profil dit européen . The present invention relates to the field of locksmithing and more precisely the locksmith assemblies comprising cylinders with a so-called European profile.
Dans le domaine de la serru rerie , on a l'habitude d' utiliser des cylindres logés dans une serrure et dont l'actionnement par une clé adaptée permet de commander l'ouverture ou la fermeture de cette serrure. Ces cylindres comportent un stator à l'intérieur duquel est adapté à tourner un rotor lorsqu'une clé de dimensions et de formes adaptées est insérée . L'extrémité du rotor orientée vers l'extérieur de la serrure présente une fente d'insertion de clé tandis que l'extrémité opposée d u rotor, tou rnée vers l'intérieur de la serrure , est prolongée axialement hors d u stator par des moyens d'embrayage d'un élément rotatif destiné à l'actionnement d u pêne de la serrure.  In the field of tightening, it is customary to use cylinders housed in a lock and whose actuation by a suitable key makes it possible to control the opening or closing of this lock. These cylinders comprise a stator inside which is adapted to rotate a rotor when a key of dimensions and adapted shapes is inserted. The end of the rotor facing outwardly of the lock has a key insertion slot while the opposite end of the rotor, all the way towards the inside of the lock, is extended axially out of the stator by means of clutch of a rotary member for actuating the bolt of the lock.
Parmi ces cylind res, on appelle cylind res à profil d it eu ropéen ceux dont le corps d u cylindre présente un prolongement latéral de forme sensiblement oblong ue . Lorsqu'un tel cylind re est fixé dans le volume de la serru re, le prolongement latéral est disposé verticalement sous le corps du cylindre.  Among these cylinders, cylinders with a European profile are those in which the cylinder body has a lateral extension of substantially elongate shape. When such a cylinder re is fixed in the volume of the serrre re, the lateral extension is disposed vertically under the body of the cylinder.
On connaît des cylindres à profil dit européen à deux entrées, q ui consistent en un cylindre monobloc qui présente à chaque extrémité axiale une fente d'insertion de clé, de telle sorte qu'un unique cylind re , de longueur sensiblement égale à l'épaisseur de la porte, permet de présenter une fente d 'insertion des deux côtés de la porte. Un élément rotatif central est adapté à être logé au centre de ce cylind re monobloc de manière à embrayer avec chacun des deux rotors. Ces cylindres présentent une taille standard , en fabrication industrielle , de sorte qu'il n'est pas possible de se régler sur l'épaisseur d' une porte légèrement d ifférente des standards sans que l'extrémité d u rotor formant la face d'entrée de la clé ne dépasse légèrement de la porte .  Known European profile cylinders with two inputs, which consist of a one-piece cylinder which has at each axial end a key insertion slot, so that a single cylinder re, of length substantially equal to the thickness of the door, allows to present an insertion slot on both sides of the door. A central rotary member is adapted to be housed in the center of this monobloc cylinder so as to engage with each of the two rotors. These cylinders have a standard size, in industrial manufacture, so that it is not possible to adjust to the thickness of a door slightly different from the standards without the end of the rotor forming the entrance face the key just protrudes slightly from the door.
Or, le fait que le rotor dépasse de l'épaisseur de la porte pose un problème de sécurité . Dans le domaine de la serrurerie, on doit préven ir des tentatives d'effraction . U n procédé d'effraction usuel consiste à détruire le cylindre à profil dit européen et il est facile de, lorsque celui-ci dépasse de la porte, serrer avec une pince de blocage la partie du rotor en saillie et de la faire tourner pour provoquer une cassure de la partie centrale de l'ensemble, au niveau de l'élément rotatif. Le cylindre se casse généralement très facilement en deux et lorsque la partie cassée est retirée, l'accès au pêne est libre. However, the fact that the rotor exceeds the thickness of the door poses a security problem. In the field of locksmithing, burglary attempts must be prevented. A break-in process common is to destroy the so-called European profile cylinder and it is easy, when it exceeds the door, clamp with a clamp the part of the protruding rotor and rotate to cause a break of the central part of the assembly, at the level of the rotary element. The cylinder usually breaks very easily in two and when the broken part is removed, access to the bolt is free.
Pour régler ce problème d'ajustement de la taille des cylindres à l'épaisseur de la porte, on a envisagé de disposer dans la serrure deux demi cylindres à profil dit européen de plus petite longueur que les cylindres monoblocs décrits précédemment, l'un sur l'extérieur et l'un sur l'intérieur de la porte, en reliant ces deux demi cylindres par une barrette qui vient se loger à chacune de ses extrémités axiales dans un alésage formé dans le prolongement latéral de chacun des demi cylindres. L'élément rotatif embraye d'une part avec le rotor du demi cylindre intérieur et d'autre part avec le rotor du demi cylindre extérieur. La barrette s'étend parallèlement à l'axe des demi cylindres, à l'écart de l'élément rotatif de manière à ne pas bloquer sa rotation. On peut alors prévoir des barrettes monoblocs, de différentes tailles. On choisit la taille de la barrette monobloc à utiliser en fonction de l'épaisseur de la porte pour qu'elle s'étende de l'un à l'autre des demi cylindres à profil dit européen. Le document de brevet ΕΡ067040 divulgue un tel dispositif, qui présente toutefois l'inconvénient de rester dans un montage où il n'est pas possible d'ajuster exactement la longueur de la barrette à la dimension nécessaire et où il se présente donc le risque que le cylindre extérieur dépasse de la porte, fût ce légèrement. To solve this problem of adjustment of the size of the cylinders to the thickness of the door, it has been envisaged to have in the lock two half-cylinders with a European profile of shorter length than the monoblock cylinders described above, one on the outside and one on the inside of the door, connecting these two half cylinders by a bar which is housed at each of its axial ends in a bore formed in the lateral extension of each of the half cylinders. The rotary element engages on the one hand with the rotor of the inner half-cylinder and on the other hand with the rotor of the outer half-cylinder. The bar extends parallel to the axis of the half cylinders, away from the rotary member so as not to block its rotation. One can then provide monobloc strips, of different sizes. The size of the one-piece bar to be used depending on the thickness of the door is chosen so that it extends from one to the other of the so-called European profile half-cylinders. The patent document ΕΡ067040 discloses such a device, which however has the disadvantage of remaining in an assembly where it is not possible to exactly adjust the length of the bar to the required size and where there is therefore the risk that the outer cylinder protrudes from the door, even slightly.
Suivant l'invention, on vise à la conception d'un ensemble de serrurerie qui permette un réglage possible sur une porte d'épaisseur non standard , de manière à éviter que le cylindre dépasse de la porte et de manière à supprimer ainsi toute possibilité de saisir le cylindre de l'extérieur avec une pince pour le casser. According to the invention, it is intended to design a locksmith assembly that allows a possible adjustment to a door of non-standard thickness, so as to prevent the cylinder from protruding from the door and thus to eliminate any possibility of grab the cylinder from the outside with pliers to break it.
L'invention propose ainsi, dans ce contexte, un dispositif d'accouplement de deux demi cylindres à profil dit européen par un système à barrette, dans lequel ledit système comporte deux barrettes dont chacune présente une première extrémité adaptée à être fixée à l'un des demi cylindres et une deuxième extrémité accrochée à une pièce intermédiaire de raccord qui s'étend longitudinalement entre les demi cylindres, par l'intermédiaire d'éléments d'accroché portés respectivement par ladite pièce de raccord et par ladite deuxième extrémité de la barrette. Le dispositif est réglable en ce qu'il permet des positions multiples de coopération, une barrette et/ou la pièce de raccord présentant longitudinalement une succession desdits éléments d'accroché de manière à permettre le réglage longitudinal de l'accouplement entre ladite barrette et ladite pièce de raccord . Les éléments d'accroché prennent avantageusement la forme de moyens crantés disposés en série longitudinale, en présentant une succession longitudinale d'entailles et de nervures. The invention thus proposes, in this context, a device for coupling two half cylinders with a so-called European profile by a bar system, wherein said system comprises two bars each having a first end adapted to be fixed to one of the half rolls and a second end hooked to an intermediate connecting piece which extends longitudinally between the half rolls, by via hooking elements carried respectively by said connecting piece and by said second end of the bar. The device is adjustable in that it allows multiple positions of cooperation, a bar and / or the connecting piece having longitudinally a succession of said hooked elements so as to allow the longitudinal adjustment of the coupling between said bar and said connecting piece. The hooking elements advantageously take the form of notched means arranged in longitudinal series, having a longitudinal succession of notches and ribs.
Ainsi, on permet le réglage de la distance d'accroché entre une barrette et la pièce de raccord . On comprend qu'ainsi, en proposant un certain pas entre les moyens d'accrochés en série des différentes parties adaptées à s'accoupler l'une à l'autre, on peut jouer facilement sur le pas de réglage global de l'assemblage, et l'on peut s'adapter facilement à la mise en place de cet assemblage dans des portes de n'importe quelle épaisseur. Selon que l'on propose une succession longitudinale d'éléments d'accroché sur la pièce de raccord, sur la barrette, ou sur les deux, on propose un dispositif qui permet un pas de réglage déterminé par l'écartement des éléments d'accroché et qui permet une zone élargie si les deux pièces comportent une succession d'éléments d'accroché. Thus, the adjustment of the hooking distance between a bar and the connecting piece is allowed. It is thus understood that, by proposing a certain pitch between the means of hooking in series of the different parts adapted to mate with each other, it is easy to play on the overall adjustment step of the assembly, and one can easily adapt to the establishment of this assembly in doors of any thickness. Depending on whether a longitudinal succession of elements is proposed for hanging on the connecting piece, on the bar, or on both, a device is proposed which allows a setting step determined by the spacing of the hooked elements. and which allows an enlarged area if the two parts comprise a succession of hooked elements.
La pièce intermédiaire comporte une base centrale et des parties latérales de connexion aux barrettes disposées longitudinalement de part et d'autre de la base. Ce sont ces parties latérales qui portent une succession longitudinale d'éléments d'accroché, adaptés à coopérer avec des éléments d'accroché correspondants réalisés sur une patte de connexion qui prolonge l'une des extrémités de la barrette. Avantageusement, la patte de connexion d'une barrette et la partie latérale de la pièce de raccord présentent des portions de section qui se complètent lorsqu'elles sont accouplées pour couvrir une section équivalente à celle de la barrette. Ainsi, elles assurent une forme continue dans le prolongement axial de la barrette lorsqu'elles sont accouplées et on améliore ainsi la rigidité de l'ensemble de par la continuité de la section. The intermediate piece has a central base and side connection parts to the bars arranged longitudinally on either side of the base. It is these lateral parts which carry a longitudinal succession of hooked elements, adapted to cooperate with corresponding hook elements made on a connecting tab which extends one of the ends of the bar. Advantageously, the connecting lug of a bar and the lateral part of the connecting piece have section portions which complement each other when they are coupled to cover a section equivalent to that of the bar. Thus, they ensure a continuous shape in the axial extension of the bar when they are coupled and thus improves the rigidity of the assembly by the continuity of the section.
Selon une caractéristique avantageuse de l'invention , la pièce intermédiaire est réalisée dans un matériau plus robuste que le matériau des barrettes. Ainsi on présente l'avantage de solidifier cette zone d'assemblage, par rapport à une barrette monobloc, alors que c'est cette zone qui présente le plus de risque de rupture lors d'une tentative d'effraction. According to an advantageous characteristic of the invention, the intermediate piece is made of a more robust material than the material of the bars. Thus, it has the advantage of solidifying this assembly area, compared to a monobloc strip, while it is this area that presents the most risk of rupture during an attempted break-in.
L'invention concerne également un ensemble de serrurerie dans lequel deux demi cylindres à profil dit européen, comportant chacun un prolongement latéral d'un corps dans lequel un stator est récepteur d'un rotor d'entraînement d'un élément rotatif de commande de serrure, sont accouplés par un dispositif réglable. Tel que cela a pu être précisé précédemment, le dispositif est réglable en ce qu'il comporte deux barrettes adaptées chacune à être logée dans un évidement formé dans chacun des prolongements latéraux et à s'étendre en saillie du demi cylindre correspondant pour coopérer avec une pièce intermédiaire de raccord disposée entre les deux barrettes. Il permet des positions multiples de coopération , une barrette et/ou la pièce de raccord présentant longitudinalement une succession d'éléments d'accroché de manière à permettre le réglage longitudinal de l'accouplement entre ladite barrette et ladite pièce de raccord , les éléments d'accroché prenant la forme de moyens crantés disposés en série longitudinale. Selon différentes caractéristiques de cet ensemble de serrurerie : The invention also relates to a locksmith assembly in which two half-cylinders with a so-called European profile, each comprising a lateral extension of a body in which a stator is a receiver of a driving rotor of a rotary lock-control element. , are coupled by an adjustable device. As has been previously stated, the device is adjustable in that it comprises two bars each adapted to be housed in a recess formed in each of the lateral extensions and to extend projecting from the corresponding half-cylinder to cooperate with a intermediate piece of connection disposed between the two bars. It allows multiple positions of cooperation, a bar and / or the connecting piece having longitudinally a succession of elements hooked so as to allow the longitudinal adjustment of the coupling between said bar and said connecting piece, the elements of hung in the form of notched means arranged in longitudinal series. According to different characteristics of this set of locksmith:
- les barrettes s'étendent sous l'axe commun aux rotors et à l'élément rotatif de commande. La pièce de raccord est disposée longitudinalement au niveau de l'élément rotatif de commande et elle présente un méplat sur sa face supérieure pour laisser passage à cet élément rotatif ; the bars extend below the axis common to the rotors and to the rotary control element. The connecting piece is arranged longitudinally at the level of the rotary control element and has a flat on its upper face to allow passage to this rotating element;
- des moyens sont prévus pour la fixation de la barrette dans le prolongement latéral et les parois délimitant évidement du prolongement latéral bloquent en position transversalement la barrette et la partie de la pièce de raccord qui y sont logées ; - Means are provided for fixing the bar in the lateral extension and the walls delimiting recess of the lateral extension block in position transversely the bar and the part of the connecting piece housed therein;
- les rotors sont adaptés à entraîner un élément rotatif par l'intermédiaire de moyen d'embrayage, qui présentent une dimension longitudinale équivalente à celle des barrettes, et des entretoises formant cales d'allonge sont disposées en sortie des rotors des demi cylindres de manière à prolonger les moyens d'embrayage pour que ceux-ci puissent transmettre l'effort de rotation depuis les rotors vers l'élément rotatif. the rotors are adapted to drive a rotary element by means of clutch means, which have a longitudinal dimension equivalent to that of the bars, and spacers forming spacer wedges are arranged at the output of the rotors of the half-cylinders so as to to extend the clutch means so that they can transmit the rotational force from the rotors to the rotary member.
L'invention sera maintenant plus complètement décrite à la lecture de la description suivante en référence aux figures, dans lesquelles : The invention will now be more fully described by reading the following description with reference to the figures, in which:

Tel qu'illustré sur les figures, le dispositif d'accouplement 2 selon l'invention permet de relier deux demi cylindres européens 4, et ce dispositif comporte principalement deux barrettes d'assemblage 6 adaptées à être chacune fixée sur l'un des demi cylindres ainsi qu'une pièce intermédiaire de raccord 8 qui s'étend longitudinalement entre les deux barrettes et sur laquelle l'extrémité libre des barrettes est rapportée. As illustrated in the figures, the coupling device 2 according to the invention makes it possible to connect two European half-cylinders 4, and this device mainly comprises two assembly bars 6 adapted to be each fixed on one of the half-cylinders. as well as an intermediate connecting piece 8 which extends longitudinally between the two bars and on which the free end of the bars is reported.
Ce dispositif d'accouplement s'intègre dans un ensemble de serrurerie, tel qu'illustré à titre d'exemple sur la figure 3, qui comporte deux demi cylindres européens adaptés à être disposés en regard dans l'épaisseur de la porte, l'un vers l'intérieur, l'autre vers l'extérieur. Le dispositif est particulièrement intéressant car il est réglable de sorte qu'il permet de gérer l'entraxe entre les deux demi cylindres, tel que cela sera décrit ci-après. Chaque demi cylindre à profil dit européen comporte une première partie formant une cage 10 de section circulaire ainsi qu'une deuxième partie formant un prolongement latéral 12 de cette cage. La cage est percée d'un alésage longitudinal 14 traversant adapté à recevoir un ensemble formé d'un rotor 16 et d'un stator 18, respectivement percés de trous radiaux 20 pour y loger un jeu non représenté de goupilles et de contre goupilles. Une vis de maintien, non visible sur les figures, traverse le prolongement latéral pour déboucher dans l'alésage traversant de la cage de manière à bloquer en position le stator, seul le rotor étant adapté à tourner à l'intérieur du stator sous l'effet de son actionnement par une clé adéquate. De façon connue, l'insertion dans le rotor d'une clé aux formes et aux dimensions adaptées permet la mise en place correcte de ce jeu de goupilles pour le déblocage en rotation du rotor. This coupling device is integrated in a lock assembly, as illustrated by way of example in FIG. 3, which comprises two European half-cylinders adapted to be arranged facing each other in the thickness of the door, one inward, the other outward. The device is particularly interesting because it is adjustable so that it manages the distance between the two half-cylinders, as will be described below. Each so-called European profile half-cylinder comprises a first portion forming a cage 10 of circular section and a second portion forming a lateral extension 12 of this cage. The cage is pierced with a longitudinal through bore 14 adapted to receive an assembly formed of a rotor 16 and a stator 18 respectively pierced with radial holes 20 to accommodate a set of pins and pins not shown. A holding screw, not visible in the figures, crosses the lateral extension to open into the bore through the cage so as to lock the stator in position, only the rotor being adapted to rotate inside the stator under the effect of its actuation by an adequate key. In known manner, the insertion into the rotor of a key of the shapes and dimensions adapted allows the correct setting of this set of pins for unlocking in rotation of the rotor.
Chacun des demi cylindres est orienté dans la porte de manière à ce que la fente d'insertion de la clé 22 soit accessible depuis l'extérieur de la porte. Dans cette orientation, on appelle la face intérieure du cylindre 24 la face qui est disposée dans l'épaisseur de la porte et on appelle la face extérieure du cylindre 26 la face qui est accessible pour l' utilisateur pour insérer sa clé, que ce soit d'un côté ou de l'autre de la porte. Tel qu'illustré sur la figure 3, une pièce de blindage 28, dans laquelle est aménagée une découpe équivalente à la fente d'insertion , est plaquée contre la face du rotor tournée vers l'extérieur. La rotation de l'un des rotors par l'action de la clé entraîne la rotation d'un élément rotatif 30, à panneton ou à engrenage, disposé entre les rotors 16 tel qu'illustré sur la figure 3. L'élément rotatif 30 est destiné à l'actionnement du pêne de la serrure. A cet effet, l'extrémité du rotor tournée vers l'intérieur de la porte est prolongée longitudinalement hors du stator par des moyens d'embrayage de l'élément rotatif 32. L'élément rotatif est creusé en son centre pour recevoir un entraîneur 33 adapté à coopérer avec soit les moyens d'embrayage propres au rotor de l'un des demi cylindres, soit les moyens d'embrayage propres au rotor de l'autre demi cylindre, selon le demi cylindre dans lequel la clé est insérée. Each of the half cylinders is oriented in the door so that the insertion slot of the key 22 is accessible from outside the door. In this orientation, the inside face of the cylinder 24 is called the face which is arranged in the thickness of the door and the outside face of the cylinder 26 is called the face which is accessible for the user to insert his key, whether it be on one side or the other of the door. As illustrated in FIG. 3, a shielding piece 28, in which a cutout equivalent to the insertion slot is provided, is pressed against the face of the outwardly facing rotor. The rotation of one of the rotors by the action of the key causes the rotation of a rotary element 30, bit or gear, arranged between the rotors 16 as shown in Figure 3. The rotary member 30 is intended for actuation of the bolt of the lock. For this purpose, the end of the rotor facing the inside of the door is extended longitudinally out of the stator by clutch means of the rotary member 32. The rotary element is hollowed at its center to receive a driver 33 adapted to cooperate with either the clutch means specific to the rotor of one of the half-rolls, or the clutch means specific to the rotor of the other half-cylinder, according to the half-cylinder in which the key is inserted.
Tel que cela a été décrit plus haut, chacun des demi cylindres de l'ensemble de serrurerie est un demi cylindre à profil dit européen, c'est-à-dire qu'il comporte un prolongement latéral de la cage logeant stator et rotor. Lorsqu'un tel cylindre est disposé classiquement dans la serrure, le prolongement latéral 12 s'étend verticalement sous la cage 10 logeant le stator et le rotor. Le prolongement latéral s'étend longitudinalement sur toute la longueur du demi cylindre. Un évidement 34, de section oblongue dans le plan vertical et transversal, s'étend longitudinalement à l'intérieur d u prolongement latéral, depuis la face intérieure du cylindre jusqu'à une paroi de fond qui s'étend verticalement à distance de la face extérieure du cylindre. On prévoit une pièce de blindage qui s'étend à l'intérieur du prolongement latéral entre la face extérieure et l'évidement. As described above, each of the half cylinders of the lock assembly is a so-called European profile half-cylinder, that is to say that it comprises a lateral extension of the housing housing stator and rotor. When such a cylinder is conventionally arranged in the lock, the lateral extension 12 extends vertically under the cage 10 housing the stator and the rotor. The lateral extension extends longitudinally over the entire length of the half-cylinder. A recess 34, of oblong section in the vertical and transverse plane extends longitudinally inside the lateral extension, from the inner face of the cylinder to a bottom wall which extends vertically away from the outer face of the cylinder. A shielding piece is provided which extends inside the lateral extension between the outer face and the recess.
Les demi cylindres sont raccordés longitudinalement par le dispositif d'accouplement, à hauteur des prolongements latéraux, de telle sorte que le dispositif d'accouplement s'étend sous l'axe des rotors et sous l'élément rotatif. Chacune des barrettes est fixée dans l'évidement du prolongement latéral, par l'intermédiaire d'un moyen de fixation traversant, adapté à être logé dans un alésage transversal au cylindre 36 et dans un alésage correspondant 38, sensiblement de même diamètre, transversal à la barrette. The half cylinders are connected longitudinally by the coupling device, at the height of the lateral extensions, so that the coupling device extends under the axis of the rotors and under the rotating element. Each of the bars is fixed in the recess of the lateral extension, via a through fastening means, adapted to be housed in a bore transverse to the cylinder 36 and in a corresponding bore 38, of substantially the same diameter, transverse to the bar.
Il convient que la pièce intermédiaire de raccord 8 soit placée sous l'élément rotatif. C'est en effet cette pièce intermédiaire, tel que cela sera décrit ci-après, qui présente une forme adaptée à laisser passage à l'élément rotatif de commande pour sa bonne rotation . On comprend alors que la position longitudinale de la pièce intermédiaire de raccord est figée par la conception de la serrure et l'emplacement du pêne, et que le dispositif de raccordement réglable selon l'invention permet de proposer des barrettes de plus ou moins grande taille selon la position de là pièce intermédiaire et la distance entre celle-ci et les demi cylindres à relier. Tel que cela est illustré sur les figures, on peut utiliser dans le dispositif de l'invention des barrettes de long ueurs différentes. The intermediate coupling part 8 should be placed under the rotating element. It is indeed this piece intermediate, as will be described below, which has a shape adapted to allow passage to the rotary control element for its good rotation. It is then understood that the longitudinal position of the intermediate connecting piece is fixed by the design of the lock and the location of the bolt, and that the adjustable connection device according to the invention makes it possible to propose bars of greater or lesser size. depending on the position of the intermediate piece and the distance between it and the half cylinders to be connected. As illustrated in the figures, it is possible to use in the device of the invention strips of different lengths.
De façon correspondante, les moyens d'embrayage prolongeant le rotor en direction de l'élément rotatif de commande peuvent être de plus ou moins grande taille. Tel que cela est visible sur la figure 3, on prévoit des cales 39 de section équivalente à celle du cylindre européen qui forment entretoise entre la face intérieure du cylindre et l'élément rotatif. Ces cales permettent de rigidifier l'ensemble et d'assurer le guidage longitudinal de la barrette et des moyens d'embrayage. On va maintenant décrire plus en détail le dispositif d'accouplement selon l'invention , réglable en ce qu'il permet des positions multiples de coopération de chacune des barrettes par rapport à la pièce de raccord intermédiaire. Correspondingly, the clutch means extending the rotor towards the rotary control element may be larger or smaller. As can be seen in FIG. 3, shims 39 of section equivalent to that of the European cylinder which form a spacer between the inner face of the cylinder and the rotary element are provided. These wedges make it possible to stiffen the assembly and to ensure the longitudinal guidance of the bar and the clutch means. We will now describe in more detail the coupling device according to the invention, adjustable in that it allows multiple positions of cooperation of each of the bars relative to the intermediate connection piece.
Chacune des barrettes présente la forme générale d'une barre longitudinale de section oblongue, de dimension légèrement inférieure à l'évidement de section oblongue du prolongement latéral du cylindre. Une première extrémité 40 présente une face droite, perpendiculaire à l'axe de la barrette. Cette première extrémité est adaptée à être insérée dans le demi cylindre, et la mise en position correcte de la barrette est déterminée lorsque la face droite d'extrémité de la barrette est en butée contre la paroi de fond de l'évidement. Dans cette position, la barrette est fixée à l'intérieur du cylindre par des moyens de fixation traversants les alésages 36 et 38. A l'opposée de cette première extrémité, la barrette présente sur une certaine dimension longitudinale une patte de connexion 42 présentant par rapport à la barrette une zone à section réduite par un méplat orienté longitudinalement et parallèlement au grand côté de la forme oblongue. Ici, le méplat est décalé transversalement par rapport au plan médian de la barrette parallèle au grand côté de celle-ci. De la sorte, la patte de connexion présente une portion de section oblongue, plus ou moins épaisse selon le décalage transversal du méplat, avec une face d'assemblage 44 formée par le méplat qui s'étend entre un épaulement 46 formé par la section complète de la barrette et un bord tombé 48 qui correspond à l'extrémité de la barrette tournée vers la pièce intermédiaire de raccord . Each of the bars has the general shape of a longitudinal bar of oblong section, slightly smaller in size than the recess of oblong section of the lateral extension of the cylinder. A first end 40 has a straight face, perpendicular to the axis of the bar. This first end is adapted to be inserted into the half-cylinder, and the correct positioning of the bar is determined when the right end face of the bar is in abutment against the bottom wall of the recess. In this position, the bar is fixed inside the cylinder by fixing means through the bores 36 and 38. At the opposite of this first end, the bar has on a certain longitudinal dimension a connecting lug 42 having with respect to the bar a reduced section area by a flattened longitudinally and parallel to the long side of the oblong shape. Here, the flat is shifted transversely relative to the median plane of the strip parallel to the long side thereof. In this way, the connecting lug has a portion of oblong section, more or less thick according to the transverse offset of the flat, with an assembly face 44 formed by the flat part extending between a shoulder 46 formed by the complete section. of the bar and a flange 48 which corresponds to the end of the bar facing the intermediate fitting part.
La face d'assemblage 44 de la patte de connexion présente des éléments d'accroché 50, de manière à ce que chacune des barrettes puisse être raccordée à la pièce intermédiaire par la coopération de ces éléments d'accroché et d'éléments d'accroché complémentaires 52 embarqués sur la pièce intermédiaire de raccord. Les éléments d'accroché sont disposés respectivement sur les faces d'assemblage des pattes de connexion et sur la pièce de raccord en séries longitudinales, et on fait correspondre l'un ou l'autre des éléments d'une série avec l'un ou l'autre de la série d'éléments complémentaires. Ceci permet le réglage de la distance d'accroché entre une barrette et la pièce de raccord. La pièce intermédiaire de raccord 8 comporte une base centrale 54 et deux parties latérales 56 disposées longitudinalement de part et d'autre de la base. De manière similaire à ce qui vient d'être décrit pour la patte de connexion de la barrette, les parties latérales présentent une section réduite par un méplat orienté longitudinalement et parallèlement au grand côté de la forme oblongue. Le méplat est également décalé transversalement par rapport au plan médian de la barrette parallèle au grand côté de celle-ci. De la sorte, chacune des parties latérales présente une portion de section oblongue, plus ou moins épaisse selon le décalage transversal du méplat, avec une face d'assemblage 58 formée par le méplat qui s'étend entre un épaulement formé par la base centrale et un bord tombé 60 qui correspond à l'extrémité latérale de la pièce intermédiaire de raccord . The connecting face 44 of the connecting lug has hooking elements 50, so that each of the bars can be connected to the intermediate piece by the cooperation of these hooked elements and hung elements. complementary 52 embedded on the intermediate fitting part. The hooking elements are respectively arranged on the connecting faces of the connecting lugs and on the connecting piece in longitudinal series, and one or the other of the elements of a series is made to correspond with one or the other of the series of complementary elements. This allows the adjustment of the hook distance between a bar and the connecting piece. The intermediate connecting piece 8 comprises a central base 54 and two lateral parts 56 arranged longitudinally on either side of the base. Similar to what has just been described for the connection lug of the bar, the side portions have a reduced section by a flattened longitudinally and parallel to the long side of the oblong shape. The flat is also shifted transversely to the median plane of the strip parallel to the long side thereof. In this way, each of the lateral parts has a portion of oblong section, more or less thick depending on the transverse offset of the flat, with an assembly face 58 formed by the flat portion extending between a shoulder formed by the central base and a fallen edge 60 which corresponds to the lateral end of the intermediate connecting piece.
Ce sont ces faces d'assemblage portées par la pièce intermédiaire de raccord qui présentent les éléments d'accroché complémentaires à ceux portés par les barrettes. On pourra prévoir pour cette complémentarité de disposer sur les barrettes des éléments d'accroché mâles, respectivement femelles, et de disposer sur les parties latérales de la pièce de raccord des éléments d'accroché femelles, respectivement mâles. Tel que cela est visible sur la figure 3 notamment, les faces d'assemblage des parties latérales sont orientées transversalement dans le même sens. Une telle orientation commune des deux parties latérales facilite l' usinage de la pièce de raccord. Toutefois, il sera compris que les faces d'assemblages pourraient être tournées dans des sens opposées, sans que cela ne gêne l'interchangeabilité des barrettes. It is these assembly faces carried by the intermediate connecting piece which have hooked elements complementary to those carried by the bars. For this complementarity, it will be possible to provide male and female hook members on the bars, and to arrange on the lateral parts of the connecting piece male and female hook members, respectively. As can be seen in FIG. 3 in particular, the assembly faces of the lateral parts are oriented transversely in the same direction. Such a common orientation of the two lateral parts facilitates the machining of the connecting piece. However, it will be understood that the faces of assemblies could be turned in opposite directions, without this hindering the interchangeability of the bars.
Les éléments d'accroché du dispositif selon l'invention sont disposés en séries longitudinales. On pourra distinguer dans ces séries des éléments d'accroché distaux, qui sont les éléments d'accroché disposés à l'extrémité libre de la patte de connexion ou de la partie latérale correspondante, et des éléments d'accroché proximaux. The hooked elements of the device according to the invention are arranged in longitudinal series. In these series it will be possible to distinguish distal hook elements, which are the hook elements arranged at the free end of the connection lug or of the corresponding lateral part, and proximal hook elements.
Dans le mode de réalisation préféré de l'invention, tel qu'il est illustré sur les figures, les éléments d'accroché prennent la forme de moyens crantés. On assimile ainsi les moyens d'accroché femelles aux différents crans successifs, c'est à dire aux entailles 62 faites dans la face d'assemblage, et les moyens d'accroché mâles aux nervures 64 résultantes disposées entre chaque cran . On comprendra toutefois que la forme de ces éléments d'accroché peut varier, sans sortir du contexte de l'invention, dès lors que la coopération des éléments d'accroché complémentaires permet le blocage longitudinal de la barrette concernée par rapport à la pièce intermédiaire de raccord et le déplacement relatif de ces deux pièces dans une direction transversale aux faces d'assemblage, avant que ce déplacement relatif ne soit bloqué par l'insertion de l'ensemble dans l'évidement du prolongement latéral, tel que cela sera décrit ci-après. In the preferred embodiment of the invention, as shown in the figures, the hook elements take the form of notched means. Thus, the female hooking means are assimilated to the different successive notches, that is to say the notches 62 made in the assembly face, and the male hooking means to the resulting ribs 64 arranged between each notch. However, it will be understood that the shape of these hook elements can vary, without departing from the context of the invention, since the cooperation of complementary hooking elements allows the longitudinal locking of the bar concerned with respect to the intermediate piece of connection and the relative displacement of these two parts in a direction transverse to the assembly faces, before this relative movement is blocked by the insertion of the assembly in the recess of the lateral extension, as will be described below.
Chaque série longitudinale crantée forme une succession d'entailles et de nervures qui s'étendent sur la face d'assemblage perpendiculairement à l'axe longitudinal de la barrette ou de la pièce intermédiaire de raccord. Les crans s'étendent sur toute la hauteur de la face d'assemblage, la hauteur désignant ici la dimension de plus grand coté de la section oblongue des barrettes et de la pièce de raccord . Ainsi, les entailles et les nervures présentent des dimensions adaptées à la réalisation d'un accouplement efficace, dans lequel les barrettes ne peuvent s'échapper longitudinalement par rapport à la pièce intermédiaire de raccord . Le pas entre chaque cran d'une série est avantageusement de 2,5 mm , ce qui permet un réglage très fin de i'ensemble de serrurerie dans lequel est intégré le dispositif selon l'invention . Each notched longitudinal series forms a succession of notches and ribs which extend on the assembly face perpendicularly to the longitudinal axis of the bar or the intermediate connecting piece. The notches extend over the entire height of the assembly face, the height here denoting the dimension of largest side of the oblong section of the bars and the connecting piece. Thus, the notches and the ribs have dimensions adapted to the achievement of an effective coupling, in which the bars can not escape longitudinally with respect to the intermediate fitting part. The pitch between each notch of a series is advantageously 2.5 mm, which allows a very fine adjustment of the set of locksmithing in which is integrated the device according to the invention.
La base de la pièce intermédiaire présente une face supérieure plane 66, réalisée par un méplat de telle sorte que la hauteur de la base est moindre que celle des parties latérales. La largeur de la base est au moins égale à la largeur de l'élément rotatif de commande, de telle sorte que le dégagement créé par le méplat formant la face supérieure de la base permet la rotation de l'élément rotatif lorsque celui est entraîné par l'un des rotors. La base comporte en outre un alésage transversal 68, adapté à recevoir une vis pour la fixation de la pièce de raccord dans l'épaisseur de la porte. The base of the intermediate piece has a flat upper face 66, made by a flat so that the height of the base is less than that of the side portions. The width of the base is at least equal to the width of the rotary control element, so that the clearance created by the flat part forming the upper face of the base allows the rotation of the rotary element when that is driven by one of the rotors. The base further comprises a transverse bore 68, adapted to receive a screw for fixing the connecting piece in the thickness of the door.
Il a été vu que les pattes de connexion et les parties latérales de la pièce de raccord présentent une forme de portion de section oblongue. Ces portions présentent des dimensions complémentaires de telle sorte que, lorsque les pattes de connexion et les parties latérales sont accouplées, l'ensemble couvre une section équivalente à celle des barrettes. Ainsi, on assure une forme continue dans le prolongement longitudinal de la barrette et on améliore la rigidité de l'ensemble de par la continuité de la section . De plus, un tel ensemble peut être logé dans évidement du prolongement latéral du demi cylindre, et si nécessaire . dans l'évidement correspondant du prolongement latéral des cales disposées en regard du demi cylindre, les parois délimitant les évidements de ces prolongements assurant un blocage en position de la pièce intermédiaire de raccord par rapport à la barrette rendue solidaire du cylindre par les moyens de fixation traversants. On fige ainsi la position de la pièce intermédiaire de raccord par rapport aux barrettes sans nécessiter de moyens de fixation complémentaires. La description qui précède explique clairement comment l'invention permet d'atteindre les objectifs qu'elle s'est fixés. En particulier, tel qu'il vient d'être décrit, le fait d'avoir un dispositif de raccordement des demi cylindres en plusieurs parties, avec une pièce intermédiaire de raccord , présente ainsi l'avantage de faciliter le réglage de l'entraxe entre les deux demi cylindres. D'une part, on obtient par ce dispositif un réglage entre deux positions extrêmes suffisamment éloignées l'une de l'autre, du fait de l'addition de ces zones d'accroché. Une première position extrême de réglage, correspondant à la position de rapprochement maximal des deux demi cylindres, est définie lorsque chacune des barrettes est en butée par son épaulement contre l'extrémité latérale correspondante de la pièce de raccord , tandis que la position extrême opposée, correspondant à l'écartement maximal des deux demi cylindres, est obtenue lorsque, pour chaque barrette, on fait coopérer entre eux les éléments d'accroché distaux des barrettes avec les éléments d'accroché distaux correspondants des parties latérales de la pièce intermédiaire de raccord . Entre ces deux positions extrêmes, on règle l'entraxe entre les cylindres en choisissant quels éléments d'accroché des différentes séries longitudinales présentes sur les barrettes et sur la pièce de raccord on fait coopérer les uns avec les autres. Par ailleurs, on peut définir de façon très fine cet entraxe, puisque la présence de quatre séries d'éléments d'accroché, à savoir deux portées par la pièce de raccord et une portée par chacune des deux barrettes, permet d'additionner les pas de réglage. Ceci permet de proposer des éléments d'accroché se succédant longitudinalement avec un pas très petit, pour un réglage longitudinal plus fin qui évite que l'un ou l'autre des demi cylindres ne dépasse de l'épaisseur de la porte. On peut alors limiter la portion longitudinale sur laquelle on réalise ces éléments d'accroché, pour éviter de fragiliser la structure des pièces par la diminution de leur section . Cet agencement permet en outre une disposition asymétrique des barrettes. Tel que cela est illustré à titre d'exemple, les barrettes peuvent être de différentes longueurs, et on peut en outre jouer sur l'asymétrie de l'ensemble en éloignant différemment chacune des barrettes par rapport à la pièce de raccord . It has been seen that the connecting lugs and the lateral parts of the connecting piece have a shape of oblong section portion. These portions have complementary dimensions such that, when the connecting lugs and the side portions are coupled, the assembly covers a section equivalent to that of the bars. Thus, it ensures a continuous shape in the longitudinal extension of the bar and improves the rigidity of all by the continuity of the section. In addition, such an assembly can be housed in recess of the lateral extension of the half-cylinder, and if necessary. in the corresponding recess of the lateral extension of the shims arranged facing the half-cylinder, the walls delimiting the recesses of these extensions ensuring locking in position of the intermediate connecting piece with respect to the bar secured to the cylinder by the fixing means through. This freezes the position of the intermediate piece of connection relative to the bars without the need for additional fastening means. The foregoing description clearly explains how the invention achieves the goals it has set for itself. In particular, as just described, the fact of having a device for connecting the half-cylinders in several parts, with an intermediate connecting piece, thus has the advantage of facilitating the adjustment of the distance between the two half-cylinders. On the one hand, there is obtained by this device a setting between two extreme positions sufficiently distant from each other, due to the addition of these hooked areas. A first extreme adjustment position, corresponding to the maximum approach position of the two half-cylinders, is defined when each of the bars is abutted by its shoulder against the corresponding lateral end of the connecting piece, while the opposite end position, corresponding to the maximum spacing of the two half-cylinders, is obtained when, for each bar, is made to cooperate with the distal hanging elements of the bars with the corresponding distal hook elements of the side portions of the intermediate connecting piece. Between these two extreme positions, we adjust the distance between the cylinders by choosing which elements hooked different longitudinal series present on the bars and on the connecting piece is cooperating with each other. Moreover, one can very finely define this distance, since the presence of four sets of hooked elements, namely two carried by the connecting piece and a bearing by each of the two bars, allows to add the steps adjustment. This makes it possible to propose elements of hooking succeeding one another longitudinally with a very small pitch, for a setting longitudinal finer which avoids that one or the other of the half cylinders does not exceed the thickness of the door. We can then limit the longitudinal portion on which these hook elements are made, to avoid weakening the structure of the parts by reducing their section. This arrangement also allows an asymmetrical arrangement of the bars. As illustrated by way of example, the bars can be of different lengths, and one can further play on the asymmetry of the assembly by moving differently each of the bars relative to the connecting piece.
On comprend que l'on détermine d'abord avec exactitude quelle position relative donner aux barrettes par rapport à la pièce intermédiaire de raccord avant de figer cette position . Alors, successivement, on réalise le plaquage d'une barrette contre une des parties latérales, puis on insère l'ensemble dans l'évidement du prolongement latéral d'un des demi cylindres jusqu'à la butée contre la paroi de fond de l'évidement, et on fixe la barrette dans le demi cylindre par une goupille. Cette fixation directe de la barrette bloque indirectement la pièce intermédiaire de raccord à la fois par la coopération des éléments d'accroché qui empêche le dégagement de la pièce intermédiaire de raccord dans le plan de la face de contact et par la présence des parois de l'évidement qui empêche le dégagement transversal de la pièce intermédiaire de raccord . On réalise ensuite les mêmes opérations pour l'autre barrette, étant entendu que si la dimension longitudinale de l'une des barrettes est supérieure à la dimension longitudinale du demi cylindre, il convient de rajouter des cales formant entretoise tel que cela a été décrit précédemment, et que ce sont alors ces cales qui empêchent le dégagement transversal de la pièce de raccord par rapport à la barrette qui elle est fixée par goupille dans le demi cylindre. It will be understood that the relative position to be given to the webs relative to the intermediate coupling piece before determining this position is first accurately determined. Then, successively, the plating of a bar against one of the lateral parts is carried out, then the assembly is inserted into the recess of the lateral extension of one of the half-rolls up to the abutment against the bottom wall of the recess, and the bar is fixed in the half-cylinder by a pin. This direct attachment of the bar indirectly blocks the intermediate connecting piece both by the cooperation of the hooking elements which prevents the release of the intermediate connecting piece in the plane of the contact face and the presence of the walls of the recess which prevents the transverse clearance of the intermediate fitting part. The same operations are then performed for the other bar, it being understood that if the longitudinal dimension of one of the bars is greater than the longitudinal dimension of the half-cylinder, it is necessary to add shims forming a spacer as previously described. , and that it is then these wedges that prevent the transverse clearance of the connecting piece relative to the bar which is fixed by pin in the half cylinder.
Par ailleurs, une telle réalisation est particulièrement avantageuse en ce qu'elle permet de réaliser la barrette et la pièce intermédiaire de raccord en deux matériaux différents. On pourra alors prévoir de réaliser la pièce intermédiaire de raccord dans un matériau plus robuste, en acier inoxydable par exemple, que le matériau dans lequel sont réalisées les barrettes. Ainsi on présente l'avantage de solidifier cette zone centrale d'assemblage, par rapport à une réalisation avec une barrette monobloc, alors que l'on comprend que c'est justement cette zone qui présente le plus de risque de rupture lors d'une tentative d'effraction . Moreover, such an embodiment is particularly advantageous in that it makes it possible to produce the bar and the intermediate piece of connection in two different materials. It will then be possible to provide the intermediate fitting part in a more robust material, such as stainless steel, that the material in which the bars are made. Thus, it has the advantage of solidifying this central assembly zone, compared to an embodiment with a monobloc strip, while it is understood that it is precisely this area that has the greatest risk of rupture during a attempted break-in.
Bien entendu, diverses modifications peuvent être apportées par l'homme du métier à la structure du dispositif d'accouplement et de l'ensemble de serrurerie associé, qui viennent d'être décrits à titre d'exemples non limitatifs. A titre d'exemple, on pourra modifier sans sortir du contexte de l'invention la forme des éléments d'accroché, crantés ou non, dès lors que leur disposition sur les barrettes et sur la pièce intermédiaire de raccord permettent un réglage longitudinal de l'entraxe entre les demi cylindres que le dispositif selon l'invention est adapté à relier. Of course, various modifications may be made by those skilled in the art to the structure of the coupling device and the associated lock assembly, which have just been described by way of non-limiting examples. By way of example, it will be possible to modify without departing from the context of the invention the shape of the hooked elements, notched or not, since their arrangement on the bars and on the intermediate coupling part allow a longitudinal adjustment of the distance between the half cylinders that the device according to the invention is adapted to connect.
