Description

La présente invention est relative au domaine de la serrurerie et elle concerne, plus particulièrement, les serrures du type à canons ou cylindres doubles comportant un seul organe de condamnation qui peut être commandé à partir de l'une ou l'autre face d'un panneau mobile, tel qu'une porte, sur lequel ladite serrure est montée.The present invention relates to the field of locksmithing and it relates, more particularly, to locks of the type with double barrels or cylinders comprising a single locking member which can be controlled from either side of a movable panel, such as a door, on which said lock is mounted.

De telles serrures selon le préambule de la revendication 1 sont largement connues et comportent deux cylindres contenant deux barillets délimitant chacun un canal d'entrée dans lequel sont disposés des organes mobiles dont il convient, par l'intermédiaire d'une clé, d'assurer l'alignement pour libérer la rotation du barillet par rapport au cylindre. De tels organes mobiles peuvent être des pistons, des pompes et contre-pompes, des paillettes ou d'autres organes analogues associés à des ressorts et bien connus dans la technique.Such locks according to the preamble of claim 1 are widely known and comprise two cylinders containing two barrels each delimiting an inlet channel in which are arranged movable members which it is advisable, by means of a key, to ensure alignment to release the rotation of the barrel relative to the cylinder. Such movable members can be pistons, pumps and counterpumps, flakes or the like, associated with springs and well known in the art.

Pour réaliser de telles serrures, il est habituel d'utiliser un corps en tout matériau approprié, généralement en un alliage métallique. Le corps comporte une partie cylindrique pour la réception des barillets et une partie de prolongement radial ou queue qui est, le plus souvent, réservée à la mise en place des pistons ou analogues.To make such locks, it is usual to use a body made of any suitable material, generally a metal alloy. The body comprises a cylindrical part for receiving the barrels and a radial extension part or tail which is, most often, reserved for the placement of pistons or the like.

Un tel corps est, le plus souvent, produit par usinage pour ce qui concerne les logements cylindriques des barillets, lesquels sont coaxiaux et séparés par un dégagement réservé au passage de l'organe de verrouillage commun.Such a body is, most often, produced by machining as regards the cylindrical housings of the barrels, which are coaxial and separated by a clearance reserved for the passage of the common locking member.

Une telle méthode de réalisation, pouvant être qualifiée de traditionnelle, a été utilisée depuis de nombreuses années mais connaît, actuellement, une limite, en raison de son coût de production. Il est, en effet, nécessaire de recourir à un profilé plein qu'il faut largement usiner, ce qui représente une perte inutile de matière première, généralement coûteuse. Il est, par ailleurs, nécessaire d'exécuter un certain nombre d'opérations d'usinage par reprise, qui accroissent le coût de production.Such a production method, which can be described as traditional, has been used for many years but is currently experiencing a limit due to its production cost. It is, in fact, necessary to use a solid profile which must be largely machined, which represents an unnecessary loss of raw material, generally expensive. It is, moreover, necessary to carry out a certain number of operations of machining by recovery, which increase the cost of production.

Pour tenter de réduire un tel coût, il peut être considéré une proposition formulée, notamment, par le brevet GB 1 581 095 qui préconise de réaliser deux demi-corps comportant chacun un cylindre prolongé par une queue réunie à celle du corps homologue par une clavette goupillée.In an attempt to reduce such a cost, a proposal made, in particular, by the patent may be considered GB 1,581,095 which recommends making two half-bodies each comprising a cylinder extended by a tail joined to that of the homologous body by a pinned key.

Une telle proposition permet certainement de réduire le coût de fabrication, étant donné que le profilé initial à usiner est limité à la constitution d'un demi-corps, de sorte que les opérations d'usinage sont moins nombreuses et plus faciles à exécuter.Such a proposal certainly makes it possible to reduce the manufacturing cost, since the initial profile to be machined is limited to the constitution of a half-body, so that the machining operations are fewer and easier to carry out.

Une telle proposition souffre, toutefois, d'un inconvénient certain tenant à la résistance mécanique relative qui est offerte, notamment cas d'effraction, par la liaison entre les demi-corps au moyen d'une clavette goupillée.Such a proposal suffers, however, from a certain drawback relating to the relative mechanical strength which is offered, in particular in the event of break-in, by the connection between the half-bodies by means of a pin pin.

Une autre proposition pouvant être retenue est celle fournie par le brevet FR 2 425 522, selon lequel le corps de serrure est constitué par un empilage d'une série de flasques, sensiblement identiques, qui sont fortement fixés les uns aux autres, par soudage ou brasage fort, avec éventuellement intégration d'une clavette dans la partie queue du profil et parallèlement à la partie cylindre.Another proposal that can be accepted is that provided by patent FR 2 425 522 , according to which the lock body is constituted by a stacking of a series of substantially identical flanges, which are strongly fixed to each other, by welding or strong brazing, with possible integration of a key in the tail part of the profile and parallel to the cylinder part.

Une telle méthode de fabrication supprime, pour partie, les opérations d'usinage délicates, étant donné que la définition des cylindres et des logements internes à ces derniers est déterminée par tranche au niveau de chaque flasque.Such a manufacturing method eliminates, in part, the delicate machining operations, since the definition of the cylinders and of the housings internal to the latter is determined by slice at the level of each flange.

Si une partie des objectifs est ainsi atteinte, en revanche, un tel procédé de fabrication implique des opérations de liaison délicates à conduire pour éviter de soumettre l'empilage de flasques à des déformations permanentes non maîtrisées qui autrement impliquent de recourir obligatoirement à un usinage de reprise pour que tous les organes mobiles, constitutifs d'une serrure d'un tel modèle, puissent jouer, avec intéraction mutuelle, de façon libre.If part of the objectives are thus achieved, on the other hand, such a manufacturing process involves delicate bonding operations to be carried out in order to avoid subjecting the stacking of flanges to uncontrolled permanent deformations which otherwise imply obligatory recourse to machining of recovery so that all the movable members, constituting a lock of such a model, can play, with mutual interaction, freely.

Par ailleurs, une telle méthode de construction doit aussi être considérée comme réservant un coût de production non négligeable, même si les différents flasques peuvent être obtenus par une opération d'emboutissage-découpage répétitive. En effet, il est nécessaire de disposer de montages spéciaux pour assurer un empilage indexé et aligné des différents flasques préalablement à la seconde opération de liaison mutuelle qui doit être conduite, également, de façon précise.Furthermore, such a construction method must also be considered as reserving a non-negligible production cost, even if the various flanges can be obtained by a repetitive stamping-cutting operation. Indeed, it it is necessary to have special assemblies to ensure an indexed and aligned stacking of the different flanges before the second mutual bonding operation which must also be carried out precisely.

Il faut noter enfin que tes propositions ci-dessus ne sont pas à même de répondre aux exigences nouvelles de résistance aux tentatives d'effraction qui sont commises en soumettant l'un ou l'autre des barillets à une action de rotation forcée, avec ou sans action d'arrachement axial, afin de provoquer une extraction destructrice libérant la rotation de l'organe de verrouillage condamnant l'ouverture.Finally, it should be noted that your proposals above are not able to meet the new requirements for resistance to break-in attempts which are committed by subjecting one or the other of the barrels to a forced rotation action, with or without axial tearing action, in order to cause a destructive extraction releasing the rotation of the locking member condemning the opening.

En effet, dans ces propositions, les barillets sont disposés de façon conventionnelle et n'offrent donc pas de résistance compatible avec les niveaux exigés des nouvelles normes de sécurité actuelles.In fact, in these proposals, the barrels are arranged in a conventional manner and therefore do not offer resistance compatible with the levels required by the new current safety standards.

La présente invention a pour objet de remédier aux inconvénients ci-dessus en proposant une nouvelle technique de construction d'une serrure à cylindre, à barillet tournant et à double entrée, permettant de faciliter les opérations d'usinage, de réduire le coût de ces dernières et de conduire à un ensemble fonctionnel offrant une meilleure résistance aux efforts de traction et/ou rotation imposés aux barillets contenus dans les cylindres.The object of the present invention is to remedy the above drawbacks by proposing a new technique for constructing a cylinder lock, with rotary barrel and with double entry, making it possible to facilitate the machining operations, to reduce the cost of these and lead to a functional unit offering better resistance to the tensile and / or rotation forces imposed on the barrels contained in the cylinders.

Pour atteindre les objectifs ci-dessus, la serrure à barillets tournants, du type connu, est caractérisée, conformément à l'invention, en ce que le corps est constitué par :

  • une poutre rectiligne,
  • deux coquilles qui sont adaptées sur les parties terminales de la poutre, qui délimitent, parallèlement à cette dernière, deux logements cylindriques coaxiaux, ouverts et qui ménagent entre elles un dégagement,
  • deux douilles montées dans les logements, offrant chacune une ouverture d'entrée sur la face correspondante transversale extrême de la coquille et contenant les barillets liés par un entraîneur,
  • et des moyens de liaison angulaire et axiale entre la poutre, les coquilles et les douilles.
To achieve the above objectives, the rotary cylinder lock, of the known type, is characterized, in accordance with the invention, in that the body consists of:
  • a straight beam,
  • two shells which are fitted on the end parts of the beam, which delimit, parallel to the latter, two coaxial cylindrical housings, open and which provide clearance between them,
  • two sockets mounted in the housings, each offering an entry opening on the corresponding extreme transverse face of the shell and containing the barrels linked by a trainer,
  • and angular and axial connection means between the beam, the shells and the sockets.

Diverses autres détails ressortent de la description faite ci-dessous en référence aux dessins annexés qui montrent, à titre d'exemples non limitatifs, des formes de réalisation de l'objet de l'invention.Various other details will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

La fig. 1. est une coupe-élévation d'une serrure conforme à l'invention. Fig. 1 . is a sectional elevation of a lock according to the invention.

La fig. 2 est une coupe transversale prise selon la ligne II-II de la fig. 1. Fig . 2 is a cross section taken along line II-II of FIG. 1 .

La fig. 3 est une vue en perspective montrant, plus en détail, la conformation de l'un des éléments constitutifs de la serrure. Fig. 3 is a perspective view showing, in more detail, the conformation of one of the constituent elements of the lock.

Les fig. 4 et 5 sont des vues analogues aux fig. 1 et 2, mais correspondant à une variante de réalisation de l'objet de l'invention. Figs. 4 and 5 are views similar to FIGS . 1 and 2 , but corresponding to an alternative embodiment of the subject of the invention.

Selon le premier exemple de réalisation illustré par les fig. 1 à 3, la serrure à deux cylindres et à double entrée est constituée par deux sous-ensembles 1a et 1b qui sont symétriques par rapport à un plan P-P' considéré comme transversal à l'axe de symétrie x-x' des ensembles 1. En raison du caractère de symétrie, la description qui suit n'est faite qu'en relation avec l'un des sous-ensembles, tel que le sous-ensemble 1a , étant entendu que les mêmes références, affectées de l'indice b , désignent les mêmes éléments constitutifs du sous-ensemble 1b .According to the first exemplary embodiment illustrated by FIGS . 1 to 3 , the lock with two cylinders and double entry consists of two sub-assemblies 1 a and 1 b which are symmetrical with respect to a plane P-P ' considered to be transverse to the axis of symmetry x-x' of the assemblies 1 . Due to the character of symmetry, the following description is made only in relation to one of the subsets, such as the subset 1 a , it being understood that the same references, assigned the index b , denote the same constituent elements of the sub-assembly 1 b .

Le sous-ensemble 1a comprend une coquille 2a délimitant un cylindre 3a qui est ouvert à ses deux extrémités et dont l'axe coïncide avec l'axe x-x'. La coquille 2a est prolongée, à partir de sa face extérieure, par une barrette radiale 4a qui s'étend au-delà de la coquille 2a en définissant, par sa face tournée vers l'axe x-x', un segment 5a de paroi concave centré sur l'axe x-x' et matérialisant un prolongement de la surface périphérique extérieure de la coquille 2a .The sub-assembly 1 a comprises a shell 2 a delimiting a cylinder 3 a which is open at its two ends and whose axis coincides with the axis x-x ' . The shell 2 a is extended, from its outer face, by a radial bar 4 a which extends beyond the shell 2 a by defining, by its face facing the axis x-x ' , a segment 5 a concave wall centered on the axis x-x ' and materializing an extension of the outer peripheral surface of the shell 2 a .

Le cylindre 3a est occupé par la partie décolletée 6a d'une douille 7a cylindrique, tubulaire, qui est centrée ou indexée dans la coquille, par l'intermédiaire d'une goupille 8a engagée dans un trou 9a de la barrette 4a pour faire saillie en partie à l'intérieur d'une encoche ouverte 10a présentée par la douille 7a à partir de son bord transversal opposé à la coquille 2a . La position d'engagement axial de la douille 7a à l'intérieur du cylindre 3a est déterminée par un épaulement 11a formé dans la zone frontière de la partie décolletée 6a et destiné à coopérer avec le bord correspondant 12a de la douille 2a . L'immobilisation axiale est aussi conférée par une seconde référence formée par un épaulement 13a prenant appui contre un rebord de butée 14a qui est présenté par la paroi périphérique du cylindre 3a , dans le plan de la façade 15a de la coquille 2a .The cylinder 3a is occupied by the low-cut part 6 has a bushing 7 has cylindrical, tubular, which is centered or indexed in the shell, through a pin 8 is engaged in a hole 9a of the bar 4 has to protrude partly within an open slot 10 presented by the sleeve 7 has from its transverse edge opposite to the shell 2 a. The axial engagement position of the sleeve 7 a inside the cylinder 3 a is determined by a shoulder 11 a formed in the border area of the low-cut part 6 a and intended to cooperate with the corresponding edge 12 a of the sleeve. 2 a . The axial immobilization is conferred by a second reference formed by a shoulder 13 is supported against an abutment flange 14 a which is presented by the peripheral wall of the cylinder 3a, in the plane of the front panel 15 a of the shell 2 a .

La douille 7a définit un logement cylindrique 16a qui est réservé au montage d'un mécanisme de condamnation 17a constitué par un barillet contenant intérieurement des organes mobiles 18a , généralement associés à des organes élastiques de rappel et délimitant un fouillot 19a d'engagement d'une clé dont le profil correspond aux caractéristiques structurelles et dimensionnelles du mécanisme. Le fouillot 19a est ménagé en coïncidence d'une ouverture de façade ou d'entrée 20a s'ouvrant sur la face 15a .The socket 7 a defines a cylindrical housing 16 a which is reserved for mounting a locking mechanism 17 a constituted by a barrel internally containing movable members 18 a , generally associated with elastic return members and delimiting a nut 19 a d engagement of a key whose profile corresponds to the structural and dimensional characteristics of the mechanism. The follower 19 a is formed coincident with a front or entrance opening 20 a opening on the face 15 a .

Dans le cas présent, les organes mobiles 18a sont constitués par des pompes à coulissement axial dont les longueurs sont déterminées, en fonction d'un codage dimensionnel, en relation avec des ailettes axiales présentées par la clé. De la sorte des crans, tels que 21a , présentés par les différents éléments mobiles 18a , peuvent être amenés simultanément en relation avec un foncet ou analogue 22a présentant des découpes d'engagement des pistons pour assurer, à l'état de repos, l'immobilisation angulaire du barillet 17a à l'intérieur du logement cylindrique 16a .In the present case, the movable members 18 a are constituted by axial sliding pumps, the lengths of which are determined, as a function of a dimensional coding, in relation to the axial fins presented by the key. In this way notches, such as 21 a , presented by the different mobile elements 18 a , can be brought simultaneously in relation to a bolt or the like 22 a having cutouts for engaging the pistons to ensure, in the rest state , the angular immobilization of the barrel 17 a inside the cylindrical housing 16 a .

Lorsque les différents crans 21a sont en coïncidence avec le plan du foncet, une rotation peut intervenir pour faire tourner un entraîneur 23 qui est commun au barillet 17b . L'entraîneur 23 supporte un panneton 24 immobilisé angulairement et pourvu d'un pêne 25 constituant l'organe de verrouillage de la serrure. Le panneton 24 est monté entre deux bagues de centrage 26a et 26b , fermant les extrémités ouvertes correspondantes des douilles 7a et 7b et chargées de délimiter entre elles et en alignement avec les faces correspondantes des barrettes 4a et 4b , un dégagement 27 dans lequel peut tourner le pêne 25. Les bagues de fermeture et de centrage 26a et 26b assurent l'immobilisation des barillets 17a et 17b contre les fouillots 19a et 19b des douilles 7a et 7b .When the various notches 21a are coincident with the plane of Foncet, rotation is operative to rotate a driver 23 which is common to the barrel 17b. The driver 23 supports a bit 24 angularly immobilized and provided with a bolt 25 constituting the locking member of the lock. The bit 24 is mounted between two centering rings 26 a and 26 b , closing the corresponding open ends of the sockets 7 a and 7 b and responsible for delimiting between them and in alignment with the corresponding faces of the bars 4 a and 4 b , a clearance 27 in which the bolt 25 can rotate. The closure and centering rings 26 a and 26 b ensure the immobilization of the barrels 17 a and 17 b against the nuters 19 a and 19 b of the sockets 7 a and 7 b .

Dans certains cas, chaque sous-ensemble 1 peut comporter en plus un système de verrouillage annexe 28a s'étendant selon une direction radiale dans la barrette 4 et à travers la douille 6a et le barillet. Le système 28a comprend un dé 29a traversant et en partie engagé dans le barillet. Le dé 29a est sollicité, par un ressort 30a , pour pousser un pion 31 à travers le barillet pour faire saillie dans le fouillot 19 sur le trajet du talon de la clé de commande. Le système 28a autorise la rotation du barillet 17a lorsque, par suite de l'engagement de la clé, l'interface entre le dé et le pion est alignée avec le cylindre 16a .In some cases, each sub-assembly 1 can comprise in addition a locking system Annex 28a extending in a radial direction in the strip 4 and through the bushing 6a and the barrel. The system 28 has a die 29 includes a through and partly engaged in the barrel. The die 29 a is biased, by a spring 30 a , to push a pin 31 through the barrel to project into the nut 19 on the path of the heel of the control key. The system 28 allows a rotation of the cylinder 17 a when, as a result of the engagement of the key, the interface between the die and the pin is aligned with the cylinder 16 a.

Il doit être considéré que des mécanismes de condamnation différant de la description ci-dessus peuvent aussi être montés dans les logements cylindriques 16a et 16b .It should be considered that locking mechanisms differing from the above description can also be mounted in the cylindrical housings 16 a and 16 b .

Selon une autre disposition caractéristique, les barrettes 4a et 4b des deux coquilles 2a et 2b sont réunies par une poutre 32 qui comporte deux tenons 33a et 33b engagés dans des mortaises ouvertes 34a et 34b présentées par les barrettes 4a et 4b entre le bord 12a de la coquille correspondante et le trou 9a de réception de la goupille 8. La hauteur de chaque tenon 33 est calculée pour que, après engagement, la partie terminale dépasse de la face 5a ou 5b et soit ainsi engagée dans une lumière oblongue 35a , 35b présentée par la douille 7a , 7b et alignée avec la mortaise 34a ou 34b par l'intermédiaire de la goupille d'indexation 8a ou 8b . La hauteur de chaque tenon est aussi calculée, comme cela apparaît à la fig. 2, de manière qu'après engagement complet, la surface transversale extrême ou un méplat 36a ou 36b , que chaque tenon présente, constitue une sorte de tas ou de butée venant fermement prendre appui sous le foncet correspondant 22a ou 22b .According to another characteristic arrangement, the bars 4 a and 4 b of the two shells 2 a and 2 b are joined by a beam 32 which comprises two tenons 33 a and 33 b engaged in open mortises 34 a and 34 b presented by the bars 4 a and 4 b between the edge 12 a of the corresponding shell and the hole 9 a for receiving the pin 8 . The height of each tenon 33 is calculated so that, after engagement, the end portion protrudes from the face 5 a or 5 b and is thus engaged in an oblong slot 35 a , 35 b presented by the socket 7 a , 7 b and aligned with mortise 34 a or 34 b via the indexing pin 8 a or 8 b . The height of each post is also calculated, as shown in fig . 2, so that after complete engagement, the transverse end surface or a flat surface 36 a or 36 b, that each pin constitutes a kind of pile or abutment firmly coming to bear under the corresponding Foncet 22 a or 22 b.

La liaison est complétée par la mise en place de goupilles transversales 37a , 37b traversant les barrettes 4a , 4b et les tenons 33a , 33b .The connection is completed by the installation of transverse pins 37 a , 37 b passing through the bars 4 a , 4 b and the pins 33 a , 33 b .

Le montage structurel, tel que décrit ci-dessus et représenté aux dessins, permet de constituer la serrure à partir de deux sous-ensembles 1a et 1b qui peuvent être réalisés séparément et aisément par des opérations d'usinage classiques ne nécessitant que des phases de reprise minimales, en raison de l'accessibilité immédiate à chacune des faces transversales, soit de la coquille, soit de la douille, soit de la poutre.The structural assembly, as described above and shown in the drawings, makes it possible to constitute the lock from two sub-assemblies 1 a and 1 b which can be produced separately and easily by conventional machining operations requiring only minimum recovery phases, due to the immediate accessibility to each of the transverse faces, either of the shell, or of the socket, or of the beam.

Il devient ainsi possible d'usiner, au moindre coût et avec précision, les pièces élémentaires qui sont à même de contenir, pour chaque sous-ensemble, un barillet dont la liaison angulaire est établie par l'intermédiaire du foncet 22.It thus becomes possible to machine, at the lowest cost and with precision, the elementary parts which are able to contain, for each sub-assembly, a barrel whose angular connection is established by means of the bolt 22 .

Le montage choisi permet d'établir un appui axial particuliérement résistant de la douille contre la coquille, par l'intermédiaire des épaulements 11a et 13a et par la coopération avec le tenon 33 qui traverse la douille.The selected assembly allows for an axial support of the sleeve particularly resistant against the shell, through flanges 11a and 13a and through cooperation with the pin 33 which passes through the sleeve.

Un tel montage permet aussi d'établir une liaison angulaire particulièrement résistante, par l'intermédiaire du foncet prenant appui sur le tas 36 que constitue chaque tenon, par l'engagement de ce dernier à l'intérieur de la lumière 35 et par l'intermédiaire de la goupille de centrage-indexation 8.Such an assembly also makes it possible to establish a particularly resistant angular connection, by means of the plug bearing on the pile 36 that each stud constitutes, by the engagement of the latter inside the lumen 35 and by the intermediate of the centering-indexing pin 8 .

Par ailleurs, la coquille 1 est fermement immobilisée sur la poutre 32 par l'engagement du tenon 33 et par la liaison transversale établie par la goupille 37 de grosse section.Furthermore, the shell 1 is firmly immobilized on the beam 32 by the engagement of the stud 33 and by the transverse connection established by the pin 37 of large section.

La poutre 32, présentant une section de forte épaisseur, établit une liaison particuliérement résistante entre les deux sous-ensembles.The beam 32 , having a very thick section, establishes a particularly resistant connection between the two sub-assemblies.

De cette manière, les tentatives d'effraction, par rotation forcée et/ou arrachement simultané selon une direction axiale, ont à vaincre des butées angulaires et axiales résistantes, qui confèrent à la serrure des caractéristiques élevées de sécurité par résistance passive.In this way, attempted break-ins, by Forced rotation and / or simultaneous tearing in an axial direction, have to overcome strong angular and axial stops, which give the lock high safety characteristics by passive resistance.

Il peut être avantageux, tel que cela apparaît aux fig. 1 et 3, de prolonger la barrette 4, radialement et en façade de la coquille, par une languette 40a , 40b dont la forme géométrique est choisie pour être égale à la section transversale offerte en bout par la poutre 32. De cette manière, lorsque la serrure à deux cylindres et à double entrées est constituée, la présentation de façade ne fait nullement apparaître la présence de la poutre 32.It may be advantageous, as shown in Figs . 1 and 3 , to extend the bar 4 , radially and in front of the shell, by a tongue 40 a , 40 b whose geometric shape is chosen to be equal to the cross section offered at the end by the beam 32 . In this way, when the lock with two cylinders and double entrances is formed, the presentation of the facade does not in any way reveal the presence of the beam 32 .

Une variante de réalisation est illustrée aux fig. 4 et 5 selon lesquelles les tenons 31a et 31b sont constitués par des pièces élémentaires indépendantes qui sont montées, par l'intermédiaire de goupilles transversales 41a , 41b dans des mortaises borgnes 42a et 42b ménagés dans la poutre 32.An alternative embodiment is illustrated in FIGS . 4 and 5 according to which the pins 31 a and 31 b are constituted by independent elementary parts which are mounted, by means of transverse pins 41 a , 41 b in blind mortises 42 a and 42 b formed in the beam 32 .

L'invention n'est pas limitée aux exemples décrits et représentés, car diverses modifications peuvent y être apportées sans sortir du cadre des revendications.The invention is not limited to the examples described and shown, since various modifications can be made thereto without departing from the scope of the claims.
