Description

La présente invention se rapporte à un dispositif de fermeture, en particulier pour porte.The present invention relates to a device for closure, especially for door.

Les dispositifs de fermeture connus comprennent généralement un boítier comportant un palâtre, auquel se rattache une têtière, et un mécanisme de fermeture, le boítier étant fermé par un couvercle qui est vissé sur le palâtre. Le boítier est prévu pour loger une serrure de sûreté agencée pour actionner un pêne dormant verrouillable par un organe de verrouillage.Known closure devices include generally a case comprising a plaster, to which attaches a headrest, and a closing mechanism, the case being closed by a cover which is screwed on the palaster. The housing is designed to accommodate a lock safety device arranged to activate a deadbolt lockable by a locking member.

Un pêne demi-tour actionné par une poignée par l'intermédiaire d'une noix est généralement également prévu. Des moyens de rappel pour ramener le pêne demi-tour dans sa position d'origine après libération de la poignée et pour fixer le pêne dormant dans sa position voulue sont connus.A latch bolt operated by a handle by the intermediary of a nut is usually also planned. Reminder means to bring back the latch bolt in its original position after liberation from the handle and to fix the deadbolt in its position wanted are known.

Par ailleurs, il est également connu de monter un dispositif de fermeture sur un tube de support. A cette fin, des ouvertures sont prévues dans le tube de support pour permettre le passage, vers la têtière, de moyens de fixation du dispositif de fermeture. Dans ce type de dispositif, d'autres ouvertures sont également prévues dans le tube de support pour permettre le passage des pênes dormant et demi-tour.Furthermore, it is also known to mount a closing device on a support tube. At this end, openings are provided in the support tube to allow the passage, towards the headrest, of means of fixing of the closing device. In this type of device, other openings are also provided in the support tube to allow the passage of deadbolts and U-turn.

Les dispositifs de fermeture connus présentent cependant des inconvénients. En effet, un premier inconvénient consiste dans l'emplacement de l'organe de verrouillage occasionnant un certain encombrement par rapport au pêne dormant comme c'est le cas dans le document FR-2632340. Un autre inconvénient réside dans l'emplacement des moyens de rappel. Ceux-ci sont généralement situés de manière à occuper un certain espace propre dont il faut tenir compte pour le dimensionnement du boítier. C'est notamment le cas lorsque les moyens de rappel sont enroulés autour du pêne demi-tour. Cette disposition des moyens de rappel peut également exposer ceux-ci à une perturbation extérieure.Known closure devices, however, have disadvantages. Indeed, a first drawback consists of the location of the locking member causing a certain bulk compared to the bolt dormant as is the case in document FR-2632340. Another drawback is the location of the means of recall. These are usually located from so as to occupy a certain clean space which is necessary take into account for the sizing of the case. It is especially the case when the return means are wrapped around the latch bolt. This provision of recall can also expose these to external disturbance.

Un autre inconvénient réside encore dans le fait que des trous de fixation sont prévus dans le tube de support pour permettre le passage des moyens de fixation du boítier de serrure, en plus des ouvertures nécessaires au passage des pênes demi-tour et dormant. La présence des trous précités dans une portion relativement réduite du tube de support affecte la résistance et la tenue de celui-ci. Cet affaiblissement du tube de support peut s'avérer particulièrement gênant en cas de tentative d'effraction du dispositif de fermeture dans la mesure où le forcement du tube de support par des personnes non autorisées s'en trouve considérablement facilité.Another disadvantage is that mounting holes are provided in the support tube to allow the passage of the fixing means of the lock box, in addition to the necessary openings the passage of the deadbolt and latch bolts. The presence the aforementioned holes in a relatively small portion of the support tube affects the strength and holding of this one. This weakening of the support tube can be particularly troublesome in the event of an attempt breaking the closure device in the measurement where the forcing of the support tube by people not allowed is considerably facilitated.

Un inconvénient supplémentaire réside dans le fait que le couvercle est amovible permettant ainsi un accès relativement aisé pour une personne non autorisée au contenu du boítier, c'est-à-dire au mécanisme de fermeture, qui est rendu possible par le démontage du couvercle du palâtre. Ceci est gênant du point de vue de la sécurité du dispositif de fermeture.An additional disadvantage is that the cover is removable allowing access relatively easy for an unauthorized person contents of the housing, that is to say the closure, which is made possible by dismantling the plaster cover. This is inconvenient from the point of view of the security of the closing device.

Un autre type de serrure destinée à être encastrée dans le chant d'une porte et comportant un pêne dormant est décrit dans le document EP-0495736A. Il s'agit cependant de serrures de type relativement classique. La serrure divulguée dans le document précité comporte un pêne dormant présentant des contours plutôt compliqués et fort irréguliers avec une surface relativement importante, c'est-à-dire encombrante. Quant à l'organe de verrouillage, il présente des contours tout aussi irréguliers tout en évoluant, lui aussi, dans un espace de fonctionnement relativement important.Another type of lock intended to be embedded in the edge of a door with a deadbolt is described in document EP-0495736A. However, it is of relatively conventional type locks. The lock disclosed in the aforementioned document includes a bolt dormant with rather complicated contours and very irregular with a relatively large surface important, that is to say bulky. As for the organ locking, it also has contours irregular while also evolving in a space relatively large operating.

Le dispositif de fermeture suivant la présente invention a pour but de remédier aux inconvénients précités. A cette fin, il est proposé selon la présente invention un dispositif de fermeture tel que défini à la revendication 1.The closure device according to the present invention aims to remedy the aforementioned drawbacks. AT To this end, it is proposed according to the present invention a closing device as defined in claim 1.

Ainsi, l'agencement indiqué est particulièrement compact tout en assurant un fonctionnement efficace et sûr de l'organe de verrouillage par son agencement guidé entre le pêne dormant et la plaque de support. Par ailleurs, l'organe de verrouillage précité est de construction très simple tout en assurant un verrouillage extrêmement efficace du pêne dormant.Thus, the arrangement indicated is particularly compact while ensuring efficient and safe operation of the locking member by its arrangement guided between the deadbolt and the support plate. Otherwise, the aforementioned locking member is of construction very simple while ensuring extremely locking effective of the deadbolt.

De plus, l'organe de verrouillage s'emboíte avec le pêne dormant de façon à le verrouiller de manière bien spécifique. Le pêne dormant présente une allure massique quasi cylindrique et compacte, tout comme l'organe de verrouillage, lui aussi particulièrement simple et réduit quant à ses dimensions. Son guidage est effectué au sein même de la plaque de support grâce à la présence du guidage, ce qui rend le fonctionnement du dispositif de fermeture particulièrement efficace et sûr, ainsi que très précis et stable.In addition, the locking member fits with the bolt sleeping so as to lock it securely specific. The deadbolt has a mass appearance almost cylindrical and compact, just like the locking, also particularly simple and reduced in size. Its guidance is carried out within the support plate thanks to the presence guidance, which makes the device work particularly effective and safe closure, as well as very precise and stable.

Grâce à la mesure définie dans la revendication 3, l'emboítement entre l'organe de verrouillage et le pêne dormant se fait par le bord d'arête du pêne dormant, mais de biais. La manoeuvre d'ouverture qui en découle s'en trouve allégée.Thanks to the measure defined in claim 3, the socket between the locking member and the bolt the deadbolt is made by the edge of the deadbolt edge, but at an angle. The resulting opening maneuver is reduced.

Un autre mode de réalisation avantageux du dispositif de fermeture suivant l'invention, est défini dans la revendication 8. Ainsi, on obtient un dispositif de fermeture dont le pêne dormant est réglable en fonction des dimensions transversales du tube de support sur lequel le dispositif de fermeture est destiné à être monté. Le nombre de possibilités de réglage dépend directement du nombre de rainures dans le pêne dormant.Another advantageous embodiment of the device closure according to the invention, is defined in the claim 8. Thus, a device for obtaining locking mechanism with adjustable deadbolt transverse dimensions of the support tube on which the closure device is intended to be mounted. The number of adjustment possibilities depends directly from the number of grooves in the deadbolt.

Un mode de réalisation supplémentaire est défini dans la revendication 9. L'organe de commande précité assure une commande de pêne fiable et efficace. En outre, la construction des premiers et deuxièmes moyens de prise s'avère simple et peu coûteuse.An additional embodiment is defined in the claim 9. The aforementioned control member ensures a reliable and efficient latch control. In addition, the construction of the first and second gripping means is simple and inexpensive.

Grâce aux mesures définies dans la revendication 11 on obtient de pouvoir réunir les premier et deuxième moyen de rappel en un seul moyen possédant deux fonctions, ce qui rend le montage sensiblement plus simple et permet d'encore réduire considérablement l'encombrement par les moyens de rappel élastiques.Thanks to the measures defined in claim 11 we obtains to be able to combine the first and second means in one medium with two functions, this which makes mounting significantly simpler and allows further considerably reduce the space occupied by elastic return means.

Avantageusement, cette construction permet en particulier de réduire considérablement l'encombrement latéral du mécanisme de fermeture suivant la direction des axes de rotation des poignées. Par ailleurs, l'encombrement dû au moyen de rappel du pêne demi-tour est éliminé, puisqu'il est logé dans l'organe de commande de celui-ci. En outre, cette disposition assure une protection efficace du moyen de rappel contre une perturbation extérieure.Advantageously, this construction allows particular to significantly reduce the footprint side of the closing mechanism in the direction axes of rotation of the handles. Otherwise, space due to the return bolt reminder is eliminated, since it is housed in the organ of command of it. In addition, this provision ensures effective protection of the return device against external disturbance.

Selon un autre mode de réalisation avantageux du dispositif de fermeture suivant l'invention, le pêne dormant présente au moins deux entailles qui sont alignées axialement et qui s'étendent transversalement par rapport à l'axe du pêne, lesdites entailles étant agencées pour coopérer avec l'organe de verrouillage.According to another advantageous embodiment of the closing device according to the invention, the bolt frame has at least two notches which are axially aligned and extending transversely relative to the axis of the bolt, said notches being arranged to cooperate with the locking member.

Une possibilité de réglage analogue pour le pêne demi-tour est prévue par l'adaptation adéquate suivant l'invention du nombre d'entailles dans le pêne demi-tour et du nombre de dents sur le pourtour de la roue. Ceci permet un décalage initial et un réglage des positions de repos respectives du pêne demi-tour et de la roue en fonction des dimensions transversales du tube de support.A similar adjustment possibility for the latch bolt is provided by the following suitable adaptation the invention of the number of taps in the latch bolt and the number of teeth around the circumference of the wheel. This allows initial offset and position adjustment respective rests of the latch bolt and the wheel function of the transverse dimensions of the support.

Suivant un mode de réalisation plus avantageux encore défini dans la revendication 14 on obtient que la réduction du nombre de trous dans le tube de support procure une augmentation sensible de la résistance et de la tenue de celui-ci. La sécurité du dispositif de fermeture s'en trouve renforcée.According to an even more advantageous embodiment defined in claim 14 we obtain that the reduction in the number of holes in the support tube provides a significant increase in resistance and holding this one. The safety of the closing device is finds reinforced.

Suivant un mode de réalisation particulièrement avantageux du dispositif de fermeture suivant l'invention chaque douille présente à son extrémité libre au moins un premier moyen de prise destiné à coopérer avec une clef de serrage extérieure qui est pourvue d'au moins un deuxième moyen de prise correspondant. Ainsi, pour desserrer les douilles qui se trouvent cachées dans le tube de support, il est nécessaire de disposer d'une clef de serrage appropriée, détenue uniquement par des personnes autorisées. En personnalisant les systèmes clef/douille, il est possible suivant la présente invention, en conférant une configuration de moyens de prise unique et personnelle, d'obtenir un dispositif de fermeture qui, une fois monté, présente une fiabilité considérable. Ainsi, en particulier, les premiers et deuxièmes moyens de prise précités sont chacun formés par une encoche et une saillie complémentaire permettant de former une liaison tenon-mortaise.According to a particularly embodiment advantage of the following closure device the invention each socket has at its end free at least a first gripping means intended for cooperate with an external tightening key which is provided with at least a second gripping means corresponding. Thus, to loosen the sockets which are found hidden in the support tube it is necessary to have an appropriate tightening key, owned only by authorized persons. In customizing the key / socket systems, it is possible according to the present invention, by conferring a configuration of single gripping means and personal, to obtain a locking device which, once mounted, has considerable reliability. So, in particular, the first and second means above are each formed by a notch and a complementary projection making it possible to form a tenon-mortise connection.

Suivant un mode de réalisation préféré du dispositif suivant l'invention, celui-ci comprend un boítier intégré présentant une forme d'étui aplati pourvu sur l'une des faces latérales d'une ouverture allongée qui est agencée pour recevoir la têtière de manière que le boítier entoure l'organe de commande et la noix, ainsi que la serrure. Grâce à la structure intégrée du boítier de serrure, dans laquelle le couvercle et le palâtre font intégralement corps l'un avec l'autre, le boítier de serrure est pratiquement inviolable et la sûreté du dispositif de fermeture s'en trouve considérablement renforcée. According to a preferred embodiment of the device according to the invention, it comprises a housing integrated in the form of a flattened case provided on one of the side faces of an elongated opening which is arranged to receive the headrest so that the housing surrounds the control member and the nut, as well than the lock. Thanks to the integrated structure of the housing lock, in which the cover and the plaster are integral with each other, the housing lock is practically inviolable and the security of the closure device is found considerably reinforced.

Des modes de réalisation supplémentaires du dispositif de fermeture suivant l'invention sont définis dans les autres sous-revendications.Additional embodiments of the device according to the invention are defined in the other subclaims.

D'autres avantages et particularités du dispositif de fermeture suivant l'invention ressortiront de la description plus détaillée donnée ci-après d'un exemple de réalisation illustré au moyen des dessins annexés.Other advantages and particularities of the closure according to the invention will emerge from the more detailed description given below of an example illustrated by means of the accompanying drawings.

La figure 1 représente une vue en perspective partiellement éclatée d'un dispositif de fermeture suivant l'invention.Figure 1 shows a perspective view partially broken out of a closing device according to the invention.

La figure 2 représente une vue en perspective éclatée d'un dispositif de fermeture suivant l'invention.Figure 2 shows an exploded perspective view of a closure device according to the invention.

Les figures 3 et 4 représentent des vues en détail d'une partie du dispositif de fermeture .Figures 3 and 4 show detailed views of a part of the closing device.

Les figures 5 et 6 illustrent chacune le fonctionnement du dispositif de fermeture dans des positions successives.Figures 5 and 6 each illustrate how it works of the closing device in positions successive.

La figure 7 illustre une vue en détail agrandi et en coupe d'une partie du dispositif de fermeture.Figure 7 illustrates an enlarged detail view and section of part of the closing device.

De manière générale, la présente invention se rapporte à un dispositif de fermeture, en particulier pour porte. Le dispositif de fermeture suivant l'invention s'applique notamment à tout type d'ouvrant - tel que portail, barrière, porte pivotante - pourvu d'un profil tubulaire de section ronde, rectangulaire ou carrée comme dans l'exemple décrit ci-après et de dimension généralement quelconque se montant sur celui-ci.In general, the present invention relates to a closing device, in particular for a door. The closure device according to the invention applies in particular to any type of opening - such as gate, barrier, hinged door - with profile tubular with round, rectangular or square section as in the example described below and of dimension generally any amount on it.

Classiquement, le dispositif de fermeture comprend un palâtre sur lequel est fixé un couvercle. En revanche, le boítier de serrure 1 suivant l'invention représenté sur la figure 1 se présente sous la forme d'un corps monobloc intégrant couvercle et palâtre en un étui à six faces 11, 12, 13, 14, 15, 16. Le boítier formant étui 1 présente sur l'une des faces 16 une ouverture 18 destinée à recevoir une têtière 2 qui est indépendante du boítier proprement dit.Conventionally, the closure device comprises a plasterboard on which is fixed a cover. On the other hand, the lock housing 1 according to the invention shown in Figure 1 is in the form of a body monobloc integrating cover and plaster in a case of six sides 11, 12, 13, 14, 15, 16. The case forming a case 1 has an opening 18 on one of the faces 16 intended to receive a headrest 2 which is independent of the case itself.

Grâce à la structure monobloc du boítier, on obtient un dispositif de fermeture dont la sûreté est considérablement renforcée car la serrure 103 est logée dans le boítier 1 installé dans la porte. En effet, le seul accès à la serrure 103 se situe dans l'ouverture latérale 18 laquelle est obturée par la têtière 2. La têtière est bloquée devant le profil tubulaire 4 sur lequel le dispositif de fermeture est monté. L'ouverture latérale 18 est ainsi parfaitement inaccessible, ce qui enlève toute possibilité d'accès au mécanisme de serrure logé dans le boítier 1. En outre, ladite structure monobloc du boítier 1 offre l'avantage de faciliter le montage de celui-ci dans la porte et de réduire ainsi considérablement le temps de montage. L'encombrement de l'ensemble formé par le boítier et la têtière en est réduit.Thanks to the monobloc structure of the case, we obtain a closing device whose safety is considerably strengthened because lock 103 is housed in the box 1 installed in the door. Indeed, the only access to lock 103 is located in the opening side 18 which is closed by the headrest 2. The headrest is locked in front of the tubular profile 4 on which the closure device is mounted. The opening side 18 is thus completely inaccessible, which removes any possibility of access to the lock mechanism housed in the housing 1. In addition, said structure monobloc of the case 1 offers the advantage of facilitating the fitting it into the door and thereby reducing considerably the assembly time. The size of the assembly formed by the housing and the headrest is reduced.

Avantageusement, le bord 17 entourant l'ouverture 18 et le bord de la têtière 2 présentent un profil biseauté permettant un emboítement rapide et sûr de l'une dans l'autre.Advantageously, the edge 17 surrounding the opening 18 and the edge of the headrest 2 have a beveled profile allowing a quick and safe fitting of one into the other.

Le boítier 1 est prévu pour loger un mécanisme de serrure permettant de commander au moins un pêne. Dans l'exemple ci-après, un mécanisme de commande d'un pêne demi-tour 5 et d'un pêne dormant 6 présentant chacun une forme allongée de la longueur prédéterminée sera décrit, comme illustré sur les figures 1 et 2. En particulier, la structure exemplaire du mécanisme décrit ci-après permet la transformation d'un mouvement de rotation d'un organe de commande 50 qui est entraíné par une poignée 101 ou 102, en un mouvement de translation du pêne 5. Chaque pêne 5, 6 est destiné à s'engager dans le profil tubulaire 4 précité sous l'action d'un organe d'actionnement respectif. Classiquement, l'organe d'actionnement du pêne demi-tour 5 est constitué par une poignée 101, 102 prévue de part et d'autre de la porte et l'organe d'actionnement du pêne dormant 6 par une clef 104, par exemple introduite dans une serrure de sûreté 103 pourvue d'un taquet d'entraínement ou panneton 105 agissant directement sur le pêne dormant 6.The housing 1 is intended to house a mechanism for lock for controlling at least one bolt. In the example below, a mechanism for controlling a bolt U-turn 5 and a deadbolt 6 each having a elongated shape of the predetermined length will be described, as illustrated in Figures 1 and 2. In particular, the exemplary structure of the mechanism described below allows the transformation of a rotational movement of a control member 50 which is driven by a handle 101 or 102, in a translational movement of the bolt 5. Each bolt 5, 6 is intended to engage in the profile tubular 4 mentioned above under the action of an organ respective actuation. Classically, the organ actuating the latch 5 is constituted by a handle 101, 102 provided on either side of the door and the deadbolt actuator 6 by a key 104, for example inserted into a lock safety 103 provided with a driving cleat or bit 105 acting directly on the deadbolt 6.

Une autre particularité consiste en ce que la course tant du pêne demi-tour 5 que du pêne dormant 6 est réglable. A cette fin, le pêne dormant 6 présente plusieurs rainures 61, 62, 63 qui sont alignées suivant l'axe longitudinal du pêne 6 tout en s'étendant pratiquement transversalement par rapport à celui-ci. Les rainures précitées sont destinées à coopérer chacune avec le taquet d'entraínement 105 de la serrure de sûreté 103. Suivant que le taquet d'entraínement 105 s'engage dans l'une ou l'autre des rainures 61, 62, 63, le pêne 6 aura une course raccourcie ou rallongée par rapport à la têtière 2. Cette possibilité de réglage de la course du pêne dormant 6 permet d'adapter la serrure à des profils tubulaires 4 de sections différentes. Ceci constitue un avantage appréciable de l'invention car il permet l'adaptation d'une seule serrure à différents types de profils tubulaires, ce qui facilite considérablement la gestion de stocks de telles serrures. Comme il est exposé ci-après, une mesure analogue est prévue pour le pêne demi-tour 5 procurant le même avantage de course réglable du pêne. Another special feature is that the race both the latch 5 and the deadbolt 6 is adjustable. To this end, the deadbolt 6 presents several grooves 61, 62, 63 which are aligned along the longitudinal axis of the bolt 6 while extending practically transverse to it. The aforementioned grooves are intended to cooperate each with the drive stop 105 of the lock safety 103. Depending on whether the driving cleat 105 engages in one or other of the grooves 61, 62, 63, bolt 6 will have a shortened or lengthened stroke by compared to the headrest 2. This possibility of adjusting the deadbolt 6 stroke allows the lock to be adapted to tubular profiles 4 of different sections. This constitutes an appreciable advantage of the invention because it allows the adaptation of a single lock to different types of tubular profiles, which facilitates considerably managing stocks of such locks. As set out below, a measurement similar is provided for the U-bolt 5 providing the same advantage of adjustable stroke of the bolt.

De manière à assurer une sûreté convenable au dispositif de fermeture, chaque pêne 5, 6 présente une longueur importante. Les pênes 5, 6 sont montés à coulissement axial dans le dispositif de fermeture. Pour permettre le coulissement des pênes, des passages sont prévus dans la têtière 2, ainsi que dans le profil tubulaire 4. Les passages 41, 42 et 43, 44, qui sont prévus respectivement pour permettre le passage des pênes demi-tour 5 et dormant 6 à travers le tube 4, sont disposés de manière mutuellement opposée sur le pourtour du tube 4 et en alignement avec le passage correspondant respectif 21, 23 dans la têtière 2. Une plaque de support 20 se rattache perpendiculairement à la têtière 2 à un bord longitudinal de celle-ci. La forme de la plaque 20 est avantageusement adaptée à la forme intérieure du boítier 1. Des éléments de guidage 22, 24 des pênes 5,6, par exemple un oeillet de guidage se rattachant à la plaque de support 20, sont agencés dans l'alignement des passages de pêne précités 21, 23. Etant donné la longueur relativement prononcée de chacun des pênes 5, 6 il est important d'assurer une excellente stabilité de guidage de ceux-ci dans leur coulissement axial. A cette fin, les éléments de guidage 22, 24 sont rattachés au bord de la plaque 20 qui est opposé à celui auquel se rattache la têtière 2, assurant ainsi un écart maximum entre les deux emplacements de guidage de chaque pêne 5, 6.In order to ensure adequate safety for the device each bolt 5, 6 has a length important. The bolts 5, 6 are slidably mounted axial in the closing device. To allow the sliding bolts, passages are provided in the headrest 2, as well as in the tubular profile 4. The passages 41, 42 and 43, 44, which are provided respectively to allow the passage of the bolts U-turn 5 and dormant 6 through the tube 4, are arranged mutually opposite on the periphery of tube 4 and in alignment with the corresponding passage respective 21, 23 in the headrest 2. A plate of support 20 attaches perpendicular to the headrest 2 at a longitudinal edge thereof. The shape of the plate 20 is advantageously adapted to the shape inside of the housing 1. Guide elements 22, 24 5,6 bolts, for example a guide eyelet attached to the support plate 20, are arranged in the alignment of the abovementioned bolt passages 21, 23. Being given the relatively pronounced length of each of the bolts 5, 6 it is important to ensure excellent guiding stability of these in their sliding axial. To this end, the guide elements 22, 24 are attached to the edge of the plate 20 which is opposite to that to which the headrest 2 is attached, thus ensuring a gap maximum between the two guide locations of each bolt 5, 6.

Comme visible sur les figures 3, 5 et 6, un oeillet de guidage supplémentaire 25, 26 est prévu pour chaque pêne dans le prolongement de chaque passage de pêne 21, 23 augmentant ainsi la surface de support de chaque pêne et donc sa stabilité.As shown in Figures 3, 5 and 6, a grommet additional guide 25, 26 is provided for each bolt in the extension of each bolt passage 21, 23 thus increasing the support surface of each bolt and therefore its stability.

Des moyens de fixation sont prévus pour fixer la têtière 2 au tube 4. Les moyens de fixation précités sont avantageusement formés par des douilles 111, 112 destinées à entrer en prise avec les passages de pêne précités 21, 23 par l'une de leurs extrémités respectives 114. Lesdites extrémités 114 des douilles 111, 112 sont avantageusement filetées et les passages de pênes 21, 23 taraudés en correspondance sur une profondeur suffisante de manière à assurer une liaison solide entre le tube de support de support 4 et le dispositif de fermeture.Fixing means are provided for fixing the headrest 2 to tube 4. The aforementioned fixing means are advantageously formed by sockets 111, 112 intended to engage with the bolt passages aforementioned 21, 23 by one of their ends respective 114. Said ends 114 of the sockets 111, 112 are advantageously threaded and the passages bolts 21, 23 tapped in correspondence on a sufficient depth to ensure a connection solid between the support support tube 4 and the closing device.

Les douilles 111, 112 sont engagées dans les passages 21, 23 par les ouvertures précitées 41, 42 et 43, 44 respectivement. Afin d'assurer un serrage commode des douilles 111, 112 dans les passages 21, 23, les douilles 111, 112 sont pourvues à leurs extrémités opposées respectives, sur leur pourtour, d'au moins un moyen de prise tel une encoche 113. Le serrage des douilles 111, 112 dans les passages 21, 23 s'effectue alors par une clef appropriée 107, de forme cylindrique ou prismatique et dont la longueur est sensiblement supérieure à la section du tube de manière à permettre la manipulation de la clef de l'extérieur. Le diamètre de la clef de serrage 107 correspond sensiblement au diamètre du pourtour de l'extrémité de la douille qui comporte l'encoche 113. La clef de serrage 107 présente à au moins une extrémité au moins une saillie 108 destinée à coopérer avec l'encoche 113. Ainsi, l'accessibilité aux douilles est rendue plus difficile après placement de celles-ci à l'intérieur du tube 4.The sockets 111, 112 are engaged in the passages 21, 23 through the aforementioned openings 41, 42 and 43, 44 respectively. In order to ensure convenient tightening of the sockets 111, 112 in passages 21, 23, the sockets 111, 112 are provided at their ends respective opposites, on their periphery, of at least one gripping means such as a notch 113. The tightening of the sockets 111, 112 in passages 21, 23 takes place then by an appropriate key 107, of cylindrical shape or prismatic and whose length is substantially greater than the section of the tube so as to allow handling the key from the outside. The diameter of the tightening key 107 corresponds substantially to the diameter of the periphery of the end of the socket which has the notch 113. The tightening key 107 has at least one end at least one projection 108 intended to cooperate with the notch 113. Thus, accessibility to sockets is made more difficult after placing them inside the tube 4.

Comme visible sur les figures 1 et 2, les douilles présentent dans la zone non filetée une portion de tête élargie 115 formant un épaulement permettant de retenir le tube 4 contre la têtière 2. La fixation par les douilles 111, 112 du dispositif de fermeture au tube 4 en faisant usage des ouvertures 41, 42 et 43, 44 qui sont en même temps destinées au passage des pênes 5 et 6 permet de limiter le nombre d'ouvertures dans le tube. En effet, aucune ouverture supplémentaire uniquement destinée aux organes de fixation n'est requise. Cela renforce la solidité du tube 4. De plus, la surface de prise relativement importante entre les douilles et les passages taraudés augmente la stabilité de liaison entre le tube 4 et le dispositif de fermeture.As shown in Figures 1 and 2, the sockets have a head portion in the unthreaded area widened 115 forming a shoulder making it possible to retain the tube 4 against the headrest 2. The fixing by the sockets 111, 112 of the closure device to the tube 4 by making use of openings 41, 42 and 43, 44 which are at the same time intended for the passage of the bolts 5 and 6 makes it possible to limit the number of openings in the tube. Indeed, no additional opening only for fasteners is not required. That reinforces the solidity of the tube 4. In addition, the surface of relatively large grip between sockets and threaded passages increases bond stability between the tube 4 and the closing device.

En outre, on peut avantageusement prévoir un agencement périphérique particulier d'encoches 113 dans les douilles 111, 112 présentant chacune un profil particulier. Dans l'exemple illustré, deux encoches diamétralement opposées sont prévues, présentant chacune un profil rectangulaire. L'avantage réside dans le fait que le desserrage des douilles 111, 112 requiert une clef 107 qui est pourvue d'une extrémité possédant un profil correspondant. Cela renforce ainsi la sécurité du dispositif de fermeture et donc la fiabilité de celle-ci, car on peut ainsi personnaliser les douilles et rendre le desserrage de celles-ci uniquement possible pour les personnes autorisées.In addition, one can advantageously provide an arrangement particular peripheral of notches 113 in the sockets 111, 112 each having a profile particular. In the example shown, two notches diametrically opposed are provided, each presenting a rectangular profile. The advantage is that that the loosening of the sockets 111, 112 requires a key 107 which is provided with an end having a corresponding profile. This strengthens the security of the closing device and therefore the reliability thereof, because you can customize the sockets and make loosening them only possible for authorized persons.

Plus particulièrement, chaque douille est creuse axialement, la paroi intérieure étant d'allure cylindrique. De manière correspondante, les pênes présentent également une allure généralement cylindrique au moins sur une partie de leur longueur. Il en résulte un autre avantage encore des douilles. Etant disposées suivant l'axe de coulissement des pênes, les douilles forment en effet un guidage supplémentaire pour les pênes comme visible sur la figure 5, contribuant ainsi à leur stabilité.More particularly, each socket is hollow axially, the inner wall having a shape cylindrical. Correspondingly, the bolts also have a generally cylindrical appearance at least over part of their length. The result yet another advantage of the sockets. Being willing along the axis of sliding of the bolts, the sockets indeed form additional guidance for bolts as shown in figure 5, thus contributing to their stability.

Dans le dispositif de fermeture suivant l'invention, l'organe de commande 50 comprend avantageusement une roue 10 qui est dentée sur au moins une partie de son pourtour, les dents 51 de celle-ci étant agencées pour entrer en prise avec les entailles 58 du pêne demi-tour 5. Le nombre d'entailles 58 et de dents 51 est prévu de manière à permettre le réglage de la course du pêne demi-tour 5 en fonction des dimensions du tube 4 conformément à ce qui a été décrit ci-dessus. La roue partiellement dentée 10 est agencée de manière sensiblement concentrique autour de la noix 3. La roue 10 présente en outre sur son pourtour un ergot d'arrêt 57 destiné à limiter la course de la roue. A cette fin, la plaque de support 20 présente sur son bord d'attaque une butée 52 destinée à limiter la course de l'ergot d'arrêt 57 de la roue. La roue est rendue solidaire de la noix 3 en se rattachant au fond de celle-ci à la plaque de support 20, de manière à former une gorge annulaire 53.In the closure device according to the invention, the control member 50 advantageously comprises a wheel 10 which is toothed on at least part of its periphery, the teeth 51 thereof being arranged for engage with the notches 58 of the latch bolt 5. The number of notches 58 and teeth 51 is expected to be so as to allow the adjustment of the bolt stroke U-turn 5 depending on the dimensions of the tube 4 in accordance with what has been described above. Wheel partially toothed 10 is arranged so substantially concentric around the nut 3. The wheel 10 also has a stop lug on its periphery 57 intended to limit the stroke of the wheel. To this end, the support plate 20 present on its leading edge a stop 52 intended to limit the travel of the lug wheel stop 57. The wheel is made integral with the nut 3 by attaching itself to the bottom of it to the support plate 20, so as to form a groove ring finger 53.

Un moyen de rappel élastique 56 est prévu lequel est destiné à ramener le pêne demi-tour 5 dans sa position de repos. Le moyen de rappel suivant l'invention est réalisé sous la forme d'un ressort spiral 59 s'enroulant autour de la noix 3 dans la gorge annulaire 53 précitée. De manière à assurer un bon maintien du ressort, une encoche 54 est prévue sur le pourtour de la roue, de préférence dans la zone non utile de celle-ci, c'est-à-dire en dehors de la zone dentée et de la zone d'ergot. L'encoche 54 sert alors de logement à une amorce 55 du ressort. De préférence, l'ensemble noix et roue dentée est agencé entre les pênes demi-tour 5 et dormant 6. Par ailleurs, l'épaisseur de la roue 10 est inférieure au diamètre du pêne demi-tour 5. Le ressort spiral 59 quant à lui est entièrement logé dans la gorge annulaire 53. Cet agencement du ressort et de la roue dentée rend ce dispositif de fermeture plus compact et il offre donc l'avantage de réduire considérablement l'encombrement de celui-ci.
De préférence, le ressort spiral 59 est métallique.
Le pêne dormant 6 présente un double alignement axial d'entailles 68 et respectivement de rainures 61,62,63. Les entailles et rainures s'étendent de préférence chacune transversalement par rapport à l'axe du pêne 6. Dans chaque alignement, le profil des rainures et respectivement des entailles est pratiquement identique. L'alignement d'entailles est tourné vers l'organe de commande 50. En regard de l'alignement d'entailles 68, un organe de verrouillage 30 servant de loqueteau est agencé à coulissement transversal par rapport à la direction de coulissement du pêne dormant 6, entre celui-ci et la plaque de support 20. Ainsi, l'organe de verrouillage est formé par exemple par une plaquette coulissante 34. Sur la plaque de support 20 est prévu un guidage 36 permettant le coulissement transversal de la plaquette 34. La plaquette 34, de préférence de forme sensiblement rectangulaire, présente ainsi un bord d'attaque 33 et un bord de fuite 37 formant rampe de loqueteau et elle est pourvue d'une languette 35 faisant saillie par rapport à la plaquette en partant de l'intérieur de la plaquette comme visible sur les figures 2 et 7. La plaquette 34 est logée à coulissement dans le guidage précité 36, entre la surface latérale 98 de la portion évidée 78 du pêne 6 et la plaque de support 20, la languette 35 étant tournée vers l'extérieur de manière à entrer en prise avec les entailles 68 du pêne dormant. Cet agencement de l'organe de verrouillage est particulièrement avantageux par son encombrement très réduit et par sa fiabilité.An elastic return means 56 is provided which is intended to return the U-bolt 5 to its rest position. The return means according to the invention is produced in the form of a spiral spring 59 winding around the nut 3 in the abovementioned annular groove 53. In order to ensure good support of the spring, a notch 54 is provided on the periphery of the wheel, preferably in the non-useful zone of the latter, that is to say outside the toothed zone and the lug area. The notch 54 then serves as a housing for a primer 55 of the spring. Preferably, the nut and toothed wheel assembly is arranged between the U-bolts 5 and the deadbolt 6. Furthermore, the thickness of the wheel 10 is less than the diameter of the U-bolt 5. The spiral spring 59 as to it is entirely housed in the annular groove 53. This arrangement of the spring and of the toothed wheel makes this closure device more compact and it therefore offers the advantage of considerably reducing the size thereof.
Preferably, the spiral spring 59 is metallic.
The deadbolt 6 has a double axial alignment of notches 68 and grooves 61, 62, 63 respectively. The notches and grooves preferably each extend transversely with respect to the axis of the bolt 6. In each alignment, the profile of the grooves and respectively of the notches is practically identical. The alignment of notches is turned towards the control member 50. Opposite the alignment of notches 68, a locking member 30 serving as a latch is arranged to slide transversely relative to the direction of sliding of the deadbolt 6, between the latter and the support plate 20. Thus, the locking member is formed for example by a sliding plate 34. On the support plate 20 is provided a guide 36 allowing the transverse sliding of the plate 34. The plate 34, preferably of substantially rectangular shape, thus has a leading edge 33 and a trailing edge 37 forming a latch ramp and it is provided with a tongue 35 projecting relative to the plate starting from the inside the plate as visible in FIGS. 2 and 7. The plate 34 is slidably housed in the aforementioned guide 36, between the lateral surface 98 of the hollowed out portion 78 of the bolt 6 and the support plate 20, the l angle 35 being turned outwards so as to engage with the notches 68 of the deadbolt. This arrangement of the locking member is particularly advantageous by its very small footprint and by its reliability.

Un autre moyen de rappel 39 est prévu en regard de la languette 35 de manière à ramener la plaquette 34 dans sa position de repos. Celui-ci est formé par exemple par un ressort de type allongé à deux branches 31, 32 en forme d'épingle à cheveux. Les branches 31, 32 du ressort présentent une longueur élevée de manière à assurer un retour efficace de la plaquette dans sa position de repos tout en ne nécessitant pas de pression trop élevée sur celle-ci grâce à l'effet de levier obtenu par la longueur des branches 31, 32 du ressort 39, qui, de préférence, est également métallique.Another reminder means 39 is provided opposite the tongue 35 so as to bring the plate 34 back into its rest position. This is formed for example by an elongated type spring with two branches 31, 32 in hairpin shape. The branches 31, 32 of spring have a long length so that ensure effective return of the wafer in its rest position while not requiring pressure too high on it due to leverage obtained by the length of the branches 31, 32 of the spring 39, which is preferably also metallic.

Les premier et deuxième moyens de rappel précités sont avantageusement réunis en un seul ressort 56. Ainsi, le ressort en épingle à cheveux 39 se rattache par l'une de ses branches 32 au ressort spiral 59, à l'extrémité libre de celui-ci. Le ressort 39 s'étend en dehors de la gorge annulaire 53, l'enveloppe cylindrique 49 de la roue 10 étant avantageusement interrompue sur une partie de son pourtour, de manière à permettre un passage commode des moyens de rappel comme visible sur les figures 2, 5 et 6. La zone d'interruption est par exemple formée par un évidement périphérique délimité latéralement par deux épaulements 45, 46 permettant une rotation de la roue 10, malgré la présence du moyen de rappel 56 qui reste pratiquement en place. La rotation précitée est ainsi limitée par les épaulements 45, 46. Ainsi, le ressort 56 suivant l'invention possède une double fonction par son action sur le pêne demi-tour et sur l'organe de verrouillage. Le nombre de pièces s'en trouve réduit, la vitesse de montage du dispositif de fermeture augmentée et l'encombrement réduit.The aforementioned first and second recall means are advantageously combined in a single spring 56. Thus, the hairpin spring 39 connects with one of its branches 32 with spiral spring 59, at the end free of it. The spring 39 extends outside the annular groove 53, the cylindrical envelope 49 of the wheel 10 being advantageously interrupted on a part of its circumference, so as to allow a passage convenient means of recall as visible on Figures 2, 5 and 6. The interruption zone is by example formed by a delimited peripheral recess laterally by two shoulders 45, 46 allowing a rotation of the wheel 10, despite the presence of the means of reminder 56 which remains practically in place. The rotation above is thus limited by the shoulders 45, 46. Thus, the spring 56 according to the invention has a double function by its action on the latch bolt and on the locking member. The number of pieces is reduced, the mounting speed of the increased closure and reduced bulk.

De préférence, la languette 35 est agencée sur un axe médian de la plaquette 34 de manière à assurer un meilleur équilibre des forces agissant sur celle-ci. Avantageusement, la languette est estampée à partir de la plaquette sans enlèvement de matière. Cela favorise considérablement la solidité et la tenue de la languette à la plaquette. La languette 35 se rattache à la plaquette 34 en un point intérieur 91 de celle-ci et s'étend linéairement suivant une pente α prédéterminée comme visible sur les figures 2,5 et 6. La languette 35 peut cependant également se rattacher à la plaquette 34 en deux points intérieurs 91, 92 de manière à former un oeillet de passage pour la branche 31 du ressort 39 comme illustré sur la figure 7.Preferably, the tongue 35 is arranged on an axis median of the insert 34 so as to ensure a better balance of forces acting on it. Advantageously, the tongue is stamped from the wafer without removing material. This favors considerably the solidity and the holding of the tongue to the brochure. The tongue 35 is attached to the plate 34 at an interior point 91 thereof and extends linearly along a predetermined slope α as shown in figures 2,5 and 6. The tongue 35 can however also be attached to the plate 34 at two interior points 91, 92 so as to form a passage eyelet for branch 31 of spring 39 as illustrated in figure 7.

Le deuxième alignement axial des rainures transversales 61,62,63 est tourné du côté opposé par rapport au pêne demi-tour et vers l'entrée 106 de la serrure ainsi qu'il ressort des figures 2, 5 et 6. Les rainures 61,62,63 sont agencées pour coopérer avec le panneton 105 de la serrure de sûreté 103. Grâce à la présence de plusieurs rainures, il est possible de régler la course du pêne dormant 6 en fonction du tube 4. Le nombre d'entailles 68 dans le pêne dormant 6 est fonction du nombre de rainures 61,62,63 dans celui-ci. Dans l'exemple illustré, on prévoit par exemple pour chaque rainure, c'est-à-dire pour chaque réglage de course du pêne 6, une entaille 68 correspondant à une position de fermeture du pêne dormant, c'est-à-dire lorsque celui-ci est en saillie par rapport au tube 4 comme représenté en traits mixtes sur la figure 1 par la référence A, et une entaille 68 correspondant à la position d'ouverture de celui-ci, c'est-à-dire lorsqu'il est à fleur par rapport au tube 4 comme représenté en traits pleins sur la figure 1 par la référence B. On pourrait cependant également prévoir une entaille supplémentaire par rainure correspondant à des serrures à double tour ou, de manière plus générale, à tour multiple.The second axial alignment of the transverse grooves 61,62,63 is turned on the opposite side with respect to the bolt turn around and towards entrance 106 of the lock as well as is shown in Figures 2, 5 and 6. The grooves 61,62,63 are arranged to cooperate with the bit 105 of the security lock 103. Thanks to the presence of several grooves, it is possible to adjust the stroke of the bolt dormant 6 depending on the tube 4. The number of notches 68 in the deadbolt 6 is a function of the number of grooves 61,62,63 in it. In the example illustrated, for example, for each groove, that is to say for each stroke adjustment of the bolt 6, a notch 68 corresponding to a position of deadbolt closure, that is to say when it protrudes from tube 4 as shown in phantom in Figure 1 by the reference A, and a notch 68 corresponding to the open position of it, that is to say when it is flush with tube 4 as shown in solid lines in FIG. 1 by the reference B. On could however also foresee a notch additional by groove corresponding to locks double turn or, more generally, turn multiple.

Dans la têtière 2, deux ouvertures 71,72 sont prévues pour le passage de vis de fixation 73,74. Une première vis de fixation 73 sert à fixer solidement la têtière 2 avec la plaque de support 20 au boítier 1. Par ailleurs, le pêne dormant 6 présente à une certaine hauteur un épaulement 79 laissant le pêne 6 tronqué longitudinalement sur une zone rétrécie du pêne 6. La zone tronquée s'étend longitudinalement à partir de l'extrémité intérieure du pêne 6 laquelle est tournée vers le boítier de serrure, jusqu'à l'épaulement 79 précité.In the headrest 2, two openings 71,72 are provided for the passage of fixing screws 73,74. A first fixing screw 73 is used to securely fix the headrest 2 with the support plate 20 in the housing 1. Furthermore, the deadbolt 6 has at a certain height a shoulder 79 leaving the bolt 6 truncated longitudinally over a narrowed area of the bolt 6. The truncated area extends longitudinally from the inner end of the bolt 6 which is turned towards the lock box, up to the shoulder 79 cited above.

La deuxième vis de fixation 74 est destinée à fixer le carter 108 de la serrure de sûreté 103 au dispositif de fermeture. A cette fin, le carter 108 est à hauteur du panneton 105, percé transversalement d'une ouverture taraudée 75 qui est placée en regard d'un pilier percé taraudé 76. En amenant la deuxième vis de fixation 74 par la têtière 2 on obtient une liaison entre la serrure de sûreté 103 et la têtière 2 qui est d'autant plus solide que la surface de prise entre la vis de fixation 74 d'une part et le pilier percé 76 et le perçage transversal 75 de la serrure d'autre part est grande. Afin d'assurer un montage plus aisé de la serrure dans le dispositif de fermeture, il est prévu une patte de retenue 77 s'étendant suivant le contour inférieur de l'entrée de serrure 106 et se rattachant au pilier percé 76 comme illustré sur la figure 3. L'évidement longitudinal 78 du pêne dormant 6 permet un alignement à la verticale du pêne demi-tour 5 et du pêne dormant 6 tout en assurant un espace suffisant au coulissement transversal précité entre le pêne dormant 6 et la plaque de support 20, de la plaquette ou du loqueteau 30. Ainsi, le dispositif de fermeture est plus compact.The second fixing screw 74 is intended to fix the casing 108 of the safety lock 103 to the closing. To this end, the casing 108 is at the height of the bit 105, pierced transversely with an opening tapped 75 which is placed opposite a pierced pillar threaded 76. Bringing the second fixing screw 74 by the headrest 2 a connection is obtained between the lock 103 and the headrest 2 which is all the more solid as the grip surface between the fixing screw 74 on the one hand and the pierced abutment 76 and the drilling transverse 75 of the lock on the other hand is large. To ensure easier mounting of the lock in the closing device, a tab is provided retainer 77 extending along the lower contour of lock entry 106 and attached to the pierced pillar 76 as illustrated in FIG. 3. The recess longitudinal 78 of deadbolt 6 allows alignment vertical of the latch 5 and the deadbolt 6 while ensuring sufficient space for sliding aforementioned transverse between the deadbolt 6 and the plate support 20, plate or latch 30. Thus, the closure device is more compact.

Une nervure d'arrêt 97 est prévue sur la face intérieure de la têtière 2, pratiquement en regard du centre de la noix 3. La nervure d'arrêt s'étend perpendiculairement à l'axe longitudinal de la têtière 2. Elle est destinée à limiter la course de la roue dentée 10 dans le sens de la saillie du pêne demi-tour 5.A stop rib 97 is provided on the inside of the headrest 2, practically opposite the center of the nut 3. The stop rib extends perpendicularly to the longitudinal axis of the headrest 2. It is intended limit the stroke of the toothed wheel 10 in the direction of the projection of the latch 5.

Le profil des entailles 68 du pêne dormant est adapté à la languette 35 de l'organe de verrouillage formant loqueteau 30, en particulier à la pente α précitée et à la largeur de celle-ci. Avantageusement, les entailles 68 sont légèrement évasées de manière à assurer un engagement de la languette 35 dans l'entaille 68 en douceur et sans à-coups, lorsque l'organe de verrouillage 30 coulisse vers le pêne dormant suivant le sens de la flèche désignée par la référence F sur la figure 5 et entre en prise avec celui-ci.The profile of the notches 68 of the deadbolt is adapted to the tongue 35 of the locking member forming latch 30, in particular at the aforementioned slope α and at the width of it. Advantageously, the notches 68 are slightly flared so as to ensure engagement of the tongue 35 in the notch 68 in smooth and smooth, when the body of locking 30 slides towards the deadbolt according to the direction of the arrow designated by the reference F on the Figure 5 and engages with it.

Le fonctionnement du dispositif de fermeture suivant l'invention est décrit ci-après, à l'aide des figures 5 et 6. Le pêne demi-tour 5 est actionné par l'une des poignées 101, 102 et le pêne dormant 6 par l'introduction d'une clef de sûreté 104 dans l'entrée de clef profilée 109 de l'un des cylindres rotatifs de la serrure de sûreté 103. Lors du montage du dispositif de fermeture, la position initiale de chaque pêne 5,6 est sélectionnée en fonction des dimensions transversales du tube de support 4. Le pêne demi-tour 5 se règle en positionnant celui-ci dans la position de recul voulue par rapport à la roue dentée 10. Il suffit de choisir la position du pêne demi-tour 5 toujours en fonction du tube de support 4 et de replacer la roue dentée 10. A cet égard, il est possible de réutiliser le dispositif de fermeture pour des tubes de support présentant des dimensions transversales différentes. Il faut alors simplement repositionner le pêne demi-tour comme décrit ci-dessus en retirant préalablement la roue dentée 10 afin d'obtenir en position de repos, la saillie appropriée de celui-ci par rapport à la surface de chant 94 du tube de support.The operation of the following closing device the invention is described below, using the Figures 5 and 6. The U-bolt 5 is actuated by one of the handles 101, 102 and the deadbolt 6 by the introduction of a security key 104 in the entrance of profiled key 109 of one of the rotary cylinders of the safety lock 103. When mounting the safety device closing, the initial position of each bolt 5.6 is selected according to the transverse dimensions of the support tube 4. The latch bolt 5 is adjusted by positioning it in the desired recoil position with respect to the toothed wheel 10. Just choose the position of the latch 5 always depending on the support tube 4 and replace the toothed wheel 10. A in this regard it is possible to reuse the device closure for support tubes having different transverse dimensions. Then simply reposition the latch bolt as described above by first removing the toothed wheel 10 in order to obtain in the rest position, the projection appropriate of it in relation to the edge surface 94 of the support tube.

Après libération de la poignée, le pêne demi-tour 5 est ramené automatiquement dans sa position de repos en saillie sous l'effet du ressort spiral 59 qui est enroulé autour de la noix 3. En effet, on tourne la poignée suivant le sens de la flèche indiqué par la référence F sur la figure 1 pour ouvrir la porte, la noix 3 et la roue 10 solidaire de celle-ci sont amenées à tourner également dans le même sens, le mouvement de rotation de la roue étant transmis au pêne demi-tour 5 de manière que celui-ci soit amené à effectuer un coulissement axial de retrait suivant la flèche indiquée par la référence G sur la figure 1 et amener le pêne demi-tour 5 en position de retrait. Le ressort, en particulier la partie enroulée 59 de celui-ci, se retrouve ainsi comprimé. Lorsque la poignée est relâchée, le ressort 56 se détend, amenant ainsi la roue 50 à sa position de départ suivant un sens de rotation opposé. La portion d'amorce 55 située à l'extrémité libre de la portion enroulée 59 du ressort 56 sert d'élément d'application à la roue. La roue 10 présente à cette hauteur un profil interrompu formant encoche 54 autour duquel la portion d'amorce 55 du ressort s'enroule.After releasing the handle, the latch bolt 5 is automatically returned to its rest position in protruding under the effect of the spiral spring 59 which is wrapped around the nut 3. Indeed, we turn the handle in the direction of the arrow indicated by the reference F in Figure 1 to open the door, the nut 3 and the wheel 10 integral with it are brought to also rotate in the same direction, the movement of rotation of the wheel being transmitted to the latch 5 so that the latter has to carry out a axial sliding of withdrawal according to the arrow indicated by the reference G in Figure 1 and bring the bolt U-turn 5 in the withdrawal position. The spring, in particularly the coiled part 59 thereof, thus finds compressed. When the handle is released, the spring 56 relaxes, thus bringing the wheel 50 to its starting position in a direction of rotation opposite. The primer portion 55 located at the end free of the coiled portion 59 of the spring 56 serves of application element to the wheel. Wheel 10 has at this height an interrupted profile forming a notch 54 around which the primer portion 55 of the spring rolls up.

Le mécanisme de mise en mouvement du pêne dormant 6 est illustré en deux états sur les figures 5 et 6. Le pêne dormant 6 coulisse axialement suivant le sens de rotation donné à la clef de sûreté 104, imprimant à son tour un mouvement de rotation suivant la flèche indiquée par la référence H au panneton 105 de la serrure de sûreté 103. Préalablement, le pêne dormant 6 est réglé en fonction des dimensions transversales du tube de support 4 comme c'est le cas pour le pêne demi-tour 5. Le réglage du pêne dormant 6 se fait en positionnant sélectivement l'une des rainures 61 du pêne dormant 6 face au panneton 105 en position d'attaque telle qu'illustrée sur la figure 5. Ainsi, le panneton 105 de la serrure se trouve face à la rainure appropriée 61 en regard des dimensions du tube de support 4. Il en résulte tout comme pour le pêne demi-tour 5, la possibilité de régler le pêne dormant 6 d'après la section du tube de support 4, et également de réutiliser le même dispositif de fermeture avec des tubes de support présentant des dimensions transversales différentes. Il suffit pour ce faire, de repositionner le pêne dormant 6 par rapport à la serrure de sûreté 103.The mechanism for setting the deadbolt 6 in motion is illustrated in two states in Figures 5 and 6. The bolt frame 6 slides axially in the direction of rotation given to safety key 104, printing to its turn a rotational movement according to the arrow indicated by the reference H to the bit 105 of the lock safety 103. Beforehand, the deadbolt 6 is adjusted according to the transverse dimensions of the tube support 4 as is the case for the U-bolt 5. The deadbolt 6 is adjusted by selectively positioning one of the grooves 61 of the bolt frame 6 facing bit 105 in attack position as shown in Figure 5. So the bit 105 of the lock is facing the appropriate groove 61 opposite the dimensions of the support tube 4. There As with the latch 5, the possibility to adjust deadbolt 6 according to support tube section 4, and also to reuse the same closing device with tubes of support having transverse dimensions different. To do this, simply reposition deadbolt 6 in relation to the safety lock 103.

Lors de sa rotation, le panneton 105 entre en contact avec le bord de fuite 37 de la plaquette 34 servant de loqueteau, laquelle jusqu'à cet instant est à l'état de repos et se trouve encore engagée par sa languette saillante 35 dans l'une des entailles 68 du pêne dormant, puis soulève celle-ci, le pêne dormant 6 restant, à ce stade du mouvement, encore immobile. Le soulèvement, à l'encontre du ressort 39, de la plaquette 34 formant organe de verrouillage par rapport au pêne dormant 6 amène la languette 35 de celle-ci à se dégager progressivement de l'entaille 68 et ainsi à libérer le pêne dormant 6. Ainsi, en poursuivant la rotation de la clef 104, le panneton poursuit son mouvement de rotation et amène ainsi le pêne dormant 6, à présent libéré, à coulisser axialement suivant le sens de la flèche indiqué par la référence E, comme visible sur les figures 1 et 6. Lorsque le panneton 105 est complètement sorti de la rainure 61 du pêne 6, l'une des entailles 68 se trouve face à la languette saillante 35 de la plaquette. Sous l'action de la partie en boucle 39, qui est comprimée, du ressort 56, la languette saillante 35 est ramenée dans l'entaille 68 qui est située en face de celle-ci. En effectuant un mouvement de coulissement retour à sa position de repos initiale, la plaquette 34 verrouille ainsi le pêne dormant 6 dans la position dans laquelle il a été amené par la rotation de la clef, à savoir d'ouverture ou de fermeture, le cas échéant à double tour.During its rotation, the bit 105 comes into contact with the trailing edge 37 of the plate 34 serving as latch, which up to this moment is in the state of rest and is still engaged by its tongue protruding 35 in one of the notches 68 of the bolt dormant, then lifts it, the deadbolt 6 remaining, at this stage of the movement, still immobile. The lifting, against spring 39, of the plate 34 forming a locking member with respect to the bolt dormant 6 causes the tongue 35 of the latter to be released gradually from the notch 68 and thus to release the deadbolt 6. Thus, by continuing the rotation of the key 104, the bit continues its rotational movement and thus brings the deadbolt 6, now released, to slide axially in the direction of the arrow indicated by the reference E, as visible on the Figures 1 and 6. When the bit 105 is completely out of the groove 61 of the bolt 6, one of the notches 68 is facing the protruding tongue 35 of the brochure. Under the action of the loop part 39, which is compressed, spring 56, the protruding tongue 35 is brought back into the notch 68 which is located opposite this one. By sliding back to its initial rest position, the plate 34 thus locks the deadbolt 6 in the position in which it was brought by the rotation of the key, to knowledge of opening or closing, if necessary at double turn.

Il découle de ce qui précède que la position des entailles 68 le long du pêne dormant 6 est déterminée par la position de la ou des rainures 61 dans celui-ci. En outre, à chaque rainure 61 correspondent avantageusement au moins deux entailles 68, l'une pour le verrouillage du pêne 6 par le loqueteau 30 en position d'ouverture et l'autre pour le verrouillage du pêne en position de fermeture. Pour des serrures à multiples tours, on prévoit des entailles 68 supplémentaires, de préférence une entaille supplémentaire par rainure 61. Il va de soi que, le cas échéant, certaines entailles pourraient faire double emploi de manière à en réduire le nombre par rapport au nombre de rainures. Par ailleurs, la largeur des rainures 61 mesurée suivant l'axe du pêne 6 par rapport à la largeur du panneton 105 est telle qu'il y a un jeu entre le panneton et chaque rainure permettant le mouvement du panneton 105 dans celle-ci comme décrit ci-dessus.It follows from the above that the position of the notches 68 along the deadbolt 6 is determined by the position of the groove or grooves 61 therein. In addition, each groove 61 corresponds advantageously at least two notches 68, one for locking the bolt 6 by the latch 30 in open position and the other for locking the bolt in the closed position. For locks with multiple turns, notches 68 additional, preferably a notch additional by groove 61. It goes without saying that, if some cuts may double employment so as to reduce the number compared to the number of grooves. In addition, the width of the grooves 61 measured along the axis of the bolt 6 relative to the width of the bit 105 is such that there is a clearance between the bit and each groove allowing the movement of bit 105 therein as described above.

Afin d'éviter un gauchissement ou un déplacement latéral non désiré de la portion en boucle 39 du ressort 56, l'oeillet de guidage 24 du pêne dormant 6 est pourvu d'une saillie 70 agencée de manière à servir de guidage à la branche libre 31 de la portion en boucle 39 du ressort 56.To avoid warping or lateral displacement unwanted from the loop portion 39 of the spring 56, the guide eye 24 of the deadbolt 6 is provided a projection 70 arranged to serve as a guide to the free branch 31 of the loop portion 39 of the spring 56.

Des garnitures de finition 99 sont avantageusement prévues sur le pourtour des passages 41, 42 et 43, 44, par exemple en matière synthétique.Finishes 99 are advantageously provided around the edges of passages 41, 42 and 43, 44, for example in synthetic material.
