Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

Le présent exposé concerne une poignée de porte permettant de mieux résister à des efforts de traction importants.The present disclosure relates to a door handle to better withstand significant traction efforts.

Une telle poignée est tout particulièrement adaptée aux portes lourdes ou de grandes dimensions et d'usage intensif comme les portes de grands magasins ou de salons d'exposition, pour ne citer que ces exemples.Such a handle is particularly suitable for heavy or large doors and heavy use as the doors of department stores or exhibition halls, to name only these examples.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Un problème récurrent des portes de grandes dimensions, telles les portes de grands magasins ou de certains lieux publics, est le desserrement et la ruine précoce de leurs poignées. En effet, ces portes sont généralement très lourdes et subissent une fréquence d'utilisation très importante atteignant parfois plusieurs centaines d'ouverture à l'heure : les poignées et leurs fixations sur le panneau de porte subissent donc des efforts importants et répétés et doivent donc être dimensionnés en conséquence.A recurring problem with large doors, such as the doors of department stores or certain public places, is the loosening and early ruin of their handles. Indeed, these doors are generally very heavy and undergo a very high frequency of use sometimes reaching several hundred hours per hour: the handles and their fasteners on the door panel are therefore subjected to significant and repeated efforts and must therefore be dimensioned accordingly.

Toutefois, malgré ce dimensionnement initial, on constate très fréquemment un desserrement des poignées qui conduit alors très rapidement à la ruine des fixations et à la dislocation des poignées.However, despite this initial dimensioning, it is very often found a loosening of the handles which then leads very quickly to the ruin of the bindings and the dislocation of the handles.

Ceci peut s'expliquer par plusieurs facteurs. En particulier, le poids et la fréquence d'utilisation des portes entrainent l'usure des pivots des portes, ce qui amène ces dernières à s'abaisser de plus en plus jusqu'à frotter sur le sol. Un tel phénomène est aggravé dans un environnement nuisible sujet à des vibrations répétées, notamment en cas de passages répétés d'un tramway ou d'un métro à proximité. En raison de ce frottement accru, les usagers doivent alors exercer une force plus importante sur la poignée pour ouvrir la porte, ce surplus d'efforts pouvant dépasser la résistance mécanique prévue des poignées.This can be explained by several factors. In particular, the weight and frequency of use of the doors cause the wear of the pivots of the doors, which causes them to lower more and more until rubbing on the ground. Such a phenomenon is aggravated in a harmful environment subject to repeated vibrations, especially in case of repeated passages of a tram or a metro nearby. Because of this increased friction, the users must then exert a greater force on the handle to open the door, this surplus effort may exceed the mechanical strength of the handles.

Cet accroissement des forces de traction subies par les fixations peut encore être démultiplié dans le cas de certaines poignées du type bâton s'étendant sur une grande longueur. Ces poignées, s'étendant parfois sur toute la hauteur de la porte, sont appréciées pour leur esthétisme et leur contribution à la rigidité du panneau de porte, tout particulièrement lorsque celui-ci est en verre. Toutefois, leur longueur est responsable d'un bras de levier très important entre les fixations de la poignée et le point d'application de la force de traction par l'utilisateur. Cet effet est maximum pour certaines portes de salons d'exposition pouvant atteindre 4m de hauteur. On comprend ainsi que tout surplus de force non prévu à la conception est décuplé et peut ainsi largement dépasser les efforts pour lesquels les fixations des poignées sont dimensionnées.This increase in tensile forces experienced by the fasteners can be further reduced in the case of some handles of the stick type extending over a great length. These handles, sometimes extending over the entire height of the door, are appreciated for their aesthetics and their contribution to the rigidity of the door panel, especially when it is glass. However, their length is responsible for a very important lever arm between the fasteners of the handle and the point of application of the traction force by the user. This effect is maximum for some showroom doors up to 4m high. It is thus understood that any surplus of force not provided for in the design is increased tenfold and can thus greatly exceed the forces for which the fasteners of the handles are dimensioned.

Naturellement, un surdimensionnement des poignées et de leurs fixations ou encore une multiplication des points de fixation seraient envisageables ; toutefois, de telles solutions ne sont pas satisfaisantes en raison de leur caractère inesthétique. D'autres solutions visent à munir les poignées de barres pleines plutôt que de tubes creux ; toutefois cela alourdit fortement la porte et interdit le passage d'éléments dans la poignée et notamment d'un mécanisme de verrouillage.Naturally, an oversizing of the handles and their fasteners or a multiplication of the attachment points would be possible; however, such solutions are unsatisfactory because of their unsightly nature. Other solutions aim at providing the handles with solid bars rather than hollow tubes; however, this greatly increases the door and prohibits the passage of elements in the handle including a locking mechanism.

Il existe donc un réel besoin pour une poignée de porte, ainsi qu'une porte, qui soient dépourvus, au moins en partie, des inconvénients inhérents aux configurations connues précitées.There is therefore a real need for a door handle, and a door, which are lacking, at least in part, the disadvantages inherent in the above known configurations.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

Le présent exposé concerne une poignée de porte du type poignée à bâton, comprenant un tube formant moyen de préhension, et au moins deux entretoises de fixation montées chacune sur le tube à l'aide d'un dispositif de montage et configurées pour être montées sur un panneau de porte ; le dispositif de montage comprend un organe élastique configuré de telle sorte que, en dessous d'une force de traction seuil exercée sur le dispositif de montage, le tube soit fixé rigidement sur l'entretoise considérée et que, au-dessus de ladite force de traction seuil, un mouvement relatif soit autorisé entre le tube et ladite entretoise.The present disclosure relates to a door handle of the stick handle type, comprising a tube forming a gripping means, and at least two fixing struts each mounted on the tube by means of a mounting device and configured to be mounted on a door panel; the mounting device comprises an elastic member configured such that, below a threshold tensile force exerted on the mounting device, the tube is fixed rigidly on the spacer in question and that, above said force of threshold tension, a relative movement is allowed between the tube and said spacer.

Ainsi grâce à un tel dispositif de montage, la poignée est munie en quelque sorte d'un disjoncteur mécanique. En effet, lorsque la porte est bien équilibrée, son pivot correctement graissé, et donc que l'effort de traction exercé sur le tube de la poignée par un utilisateur cherchant à ouvrir la porte reste raisonnable, la force de traction s'exerçant sur le dispositif de montage est insuffisante pour comprimer l'organe élastique : elle est alors directement transmise à la porte via les entretoises sans que cette force, d'amplitude raisonnable, ne puisse les endommager. La poignée se comporte ainsi comme si son tube était rigidement encastré sur ses entretoises, c'est-à-dire comme une poignée monobloc.Thus, thanks to such a mounting device, the handle is equipped in a way with a mechanical circuit breaker. Indeed, when the door is well balanced, its pivot properly greased, and therefore that the tensile force exerted on the tube of the handle by a user seeking to open the door is reasonable, the tensile force exerted on the mounting device is insufficient to compress the elastic member: it is then directly transmitted to the door via the spacers without this force of reasonable amplitude, can not damage them. The handle behaves as if its tube was rigidly embedded on its spacers, that is to say as a monobloc handle.

En revanche, lorsque la force de traction devient plus importante, par exemple lorsque la porte frotte sur le sol ou lorsqu'elle est verrouillée, et qu'elle risque de dépasser la résistance mécanique nominale des entretoises et de leurs fixations, elle devient suffisante pour comprimer l'organe élastique du dispositif de montage ce qui permet de décoller légèrement le tube de l'entretoise et donc d'offrir un degré de liberté à la poignée. Dès lors, ce degré de liberté permet d'accommoder le surplus d'efforts et un équilibre de forces s'établit entre la flexion du tube, la compression de l'organe élastique, et une composante utile permettant d'ouvrir la porte. De plus, comme le tube n'est plus rigidement fixé sur les entretoises, les dispositifs de montage ne subissent pas le surplus d'effort et ne desserrent donc pas ou en tout état de cause bien moins que si le tube était rigidement fixé sur les entretoises.However, when the pulling force becomes greater, for example when the door rubs on the floor or when it is locked, and it may exceed the nominal mechanical strength of the spacers and their fasteners, it becomes sufficient for compress the elastic member of the mounting device which allows to slightly take off the tube of the spacer and thus to offer a degree of freedom to the handle. Therefore, this degree of freedom makes it possible to accommodate the surplus forces and a balance of forces is established between the bending of the tube, the compression of the elastic member, and a useful component for opening the door. In addition, as the tube is no longer rigidly fixed on the spacers, the mounting devices do not undergo the surplus effort and therefore do not loose or in any case much less than if the tube was rigidly fixed on the spacers.

De plus, ce léger déplacement et la flexion éventuelle du tube de poignée restent de faible amplitude et donc difficilement perceptibles pour l'utilisateur.In addition, this slight displacement and the possible bending of the handle tube remain of low amplitude and therefore hardly noticeable to the user.

Ainsi, on obtient des poignées qui se desserrent moins rapidement et se détériorent donc moins rapidement que les poignées bâtons conventionnelles. Elles bénéficient donc d'une durée de vie accrue et d'un confort d'utilisation durable. Elles profitent en outre d'un esthétisme et d'une légèreté conservés.Thus, handles are obtained that loosen less quickly and therefore deteriorate less quickly than conventional stick handles. They therefore benefit from a longer life and a comfort of sustainable use. They also benefit from a conserved aesthetic and lightness.

On note en outre que cette configuration permet, dans les cas où l'amplitude prévue des forces de tractions reste dans des limites raisonnables en tout état de cause, par exemple lorsque la porte est plus petite, moins lourde, ou équipée de pivots plus performants, de remplacer l'organe élastique par un organe rigide pour assurer, sans autre adaptation nécessaire, la fixation rigide du tube de poignée sur les entretoises et donc le renfort du panneau de porte en toutes circonstances.Note also that this configuration allows, in cases where the expected amplitude of the forces of traction remains within reasonable limits in any event, for example when the door is smaller, lighter, or equipped with more efficient pivots , to replace the elastic member by a rigid member to ensure, without further adaptation, the rigid attachment of the handle tube on the spacers and therefore the reinforcement of the door panel in all circumstances.

Dans le présent exposé, on entend par « porte » tout type de porte ou de battant susceptible de fermer ou d'entraver au moins en partie un passage ou un espace : il peut s'agir d'une porte pour individus, animaux ou véhicules, d'un battant de fenêtre, d'une porte de vitrine, de meuble ou de tout autre objet, pour ne citer que ces exemples.In this presentation, the term "door" means any type of door or gate that may close or obstruct at least part of a passage or space: it may be a door for individuals, animals or vehicles , a window sash, a window door, furniture or any other object, to name only these examples.

Dans le présent exposé, les termes « proximal », « distal » et leurs dérivés sont définis par rapport au plan du panneau de porte ; en outre, les termes « intérieur », « extérieur » et leurs dérivés sont définis par rapport à la direction d'application de la force d'actionnement exercée sur le tube par l'utilisateur.In this disclosure, the terms "proximal", "distal" and their derivatives are defined relative to the plane of the door panel; in addition, the terms "inside" and "outside" and their derivatives are defined with respect to the direction of application of the actuating force exerted on the tube by the user.

Dans certains modes de réalisation, l'organe élastique est prévu entre un élément solidaire de l'entretoise et un élément solidaire du tube. En dessous de la force de traction seuil, il se comporte comme un élément rigide et assure donc la transmission directe des efforts entre le tube et l'entretoise de la même manière que si le tube avait été rigidement fixé sur l'entretoise. Au-dessus de la force de traction seuil, il se comprime en fonction de l'amplitude et du couple de la force exercée et introduit ainsi un degré de liberté entre le tube et l'entretoise.In some embodiments, the elastic member is provided between an element integral with the spacer and a member integral with the tube. Below the threshold pulling force, it behaves like a rigid element and thus ensures the direct transmission of forces between the tube and the spacer in the same way as if the tube had been rigidly fixed on the spacer. Above the threshold pulling force, it compresses as a function of the amplitude and the torque of the force exerted and thus introduces a degree of freedom between the tube and the spacer.

Dans certains modes de réalisation, l'élément solidaire de l'entretoise est une paroi interne distale de l'entretoise.In some embodiments, the integral member of the spacer is a distal inner wall of the spacer.

Dans certains modes de réalisation, une vis est fixée dans le tube et s'étend dans un espace intérieur de l'entretoise à travers un orifice pratiqué dans une paroi distale de l'entretoise.In some embodiments, a screw is secured in the tube and extends into an interior space of the spacer through an orifice in a distal wall of the spacer.

Dans certains modes de réalisation, la vis passe à travers une douille dont l'extrémité distale est en appui sur le tube et dont l'extrémité proximale présente un épaulement s'intercalant entre l'organe élastique et la tête de la vis. Grâce à cette douille, il est possible, lors du montage de la poignée, de visser la vis dans le tube au couple nominal souhaité, et ceci malgré la présence de l'organe élastique, en vissant le vis jusqu'à ce que la douille soit serrée entre le tube et la tête de la vis. En outre, en s'appuyant sur le tube plutôt que sur le fond de l'entretoise, cette douille permet de renforcer de façon importante la résistance du point de fixation, et notamment de la vis, en flexion alternée, c'est-à-dire en fatigue, retardant ainsi grandement son endommagement.In some embodiments, the screw passes through a socket whose distal end bears on the tube and whose proximal end has a shoulder interposed between the elastic member and the head of the screw. Thanks to this socket, it is possible, when mounting the handle, to screw the screw into the tube at the desired nominal torque, despite the presence of the elastic member, screwing the screw until the socket be tight between the tube and the head of the screw. In addition, by relying on the tube rather than on the bottom of the spacer, this sleeve significantly increases the resistance of the attachment point, and in particular the screw, in alternating bending, that is to say - say in fatigue, thus greatly delaying its damage.

Dans certains modes de réalisation, l'élément solidaire du tube est la tête de ladite vis. L'organe élastique est alors directement en contact avec la tête de ladite vis ou indirectement via l'épaulement de la douille le cas échéant.In some embodiments, the element integral with the tube is the head of said screw. The elastic member is then directly in contact with the head of said screw or indirectly via the shoulder of the sleeve if necessary.

Dans certains modes de réalisation, l'orifice de la paroi distale de l'entretoise possède un diamètre supérieur à celui de la tige de la vis. De préférence, son diamètre est au moins 1,5 fois supérieur, de préférence encore au moins 2 fois supérieur, au diamètre de la tige de la vis.In some embodiments, the orifice of the distal wall of the spacer has a diameter greater than that of the screw shaft. Preferably, its diameter is at least 1.5 times greater, more preferably at least 2 times greater, than the diameter of the screw shank.

Dans certains modes de réalisation, l'organe élastique est précontraint entre l'élément solidaire de l'entretoise et l'élément solidaire du tube lorsqu'aucune force de traction ne s'exerce sur le dispositif de montage.In some embodiments, the elastic member is prestressed between the element integral with the spacer and the element integral with the tube when no traction force is exerted on the mounting device.

Dans certains modes de réalisation, l'organe élastique est un ressort. On règle alors la raideur et la compression initiale du ressort pour régler ladite force de traction seuil à partir de laquelle le ressort commence à se comprimer et libère donc un degré de liberté du tube.In some embodiments, the resilient member is a spring. The stiffness and the initial compression of the spring are then adjusted to adjust said threshold pulling force from which the spring begins to compress and thus releases a degree of freedom of the tube.

Dans certains modes de réalisation, ledit ressort est un empilement d'une ou plusieurs lames ressorts. Ces lames sont faciles à mettre en place : elles permettent en outre de régler facilement la raideur du ressort en fonction du type de porte en réglant le nombre de lames empilées.In some embodiments, said spring is a stack of one or more leaf springs. These blades are easy to install: they also make it easy to adjust the stiffness of the spring depending on the type of door by adjusting the number of stacked blades.

Dans d'autres modes de réalisation, ledit ressort est un ressort hélicoïdal.In other embodiments, said spring is a coil spring.

Dans certains modes de réalisation, la force de traction seuil est comprise entre 200 et 1000 N, de préférence entre 300 et 500 N. Ces plages de valeurs correspondent aux plages de forces à partir desquelles on constate habituellement le desserrement du tube par rapport aux entretoises.In some embodiments, the tractive force threshold is between 200 and 1000 N, preferably between 300 and 500 N. These ranges of values correspond to the force ranges from which we usually find the loosening of the tube relative to the spacers .

Dans certains modes de réalisation, le dispositif de montage est configuré de manière à autoriser un degré de liberté en translation entre le tube et l'entretoise lorsque la force de traction exercée sur le dispositif de montage est supérieure à ladite force de traction seuil. Le tube peut alors se décoller de l'entretoise : n'étant plus bloqué contre l'entretoise, il peut se déformer pour consommer les efforts de flexion engendrés par le couple des forces de traction.In some embodiments, the mounting device is configured to allow a degree of freedom in translation between the tube and the spacer when the tensile force exerted on the mounting device is greater than said threshold pulling force. The tube can then be detached from the spacer: no longer being locked against the spacer, it can deform to consume the bending forces generated by the torque of the traction forces.

Dans certains modes de réalisation, le dispositif de montage est configuré de manière à autoriser un degré de liberté en rotation entre le tube et l'entretoise lorsque la force de traction exercée sur le dispositif de montage est supérieure à ladite force de traction seuil. On permet ainsi à l'élément du dispositif de montage solidaire du tube de suivre la déformation du tube : ce dernier reste alors perpendiculaire au tube de telle sorte qu'il ne subit pas d'effort de flexion. Or, il a été constaté que le couple de flexion est le principal responsable du desserrement puis de la ruine des points de fixations des poignées conventionnelles, ces derniers résistants beaucoup mieux aux efforts axiaux. Dès lors, les poignées résistent bien mieux aux efforts de traction, même accrus, et ne se desserrent pas ou bien moins que les poignées conventionnelles.In some embodiments, the mounting device is configured to allow a degree of freedom in rotation between the tube and the spacer when the tensile force exerted on the mounting device is greater than said threshold pulling force. This allows the element of the mounting device integral with the tube to follow the deformation of the tube: the latter then remains perpendicular to the tube so that it does not undergo a bending force. However, it has been found that the bending torque is the main cause of loosening and then ruining the attachment points of the conventional handles, the latter much better resistant to axial forces. From then on, the handles are much more resistant to pulling forces, even increased, and do not loosen or much less than conventional handles.

Dans certains modes de réalisation, l'entretoise possède une surface d'extrémité distale en berceau. Celle-ci permet de recevoir le tube : lorsque la force de traction est inférieure à la force seuil, le dispositif de montage maintient le tube plaqué contre cette surface en berceau, bloquant ainsi le déplacement du tube et assurant ainsi sa fixation rigide avec les entretoises. Cette surface d'extrémité distale possède de préférence un profil complémentaire à celui du tube.In some embodiments, the spacer has a distal cradle end surface. This makes it possible to receive the tube: when the pulling force is less than the threshold force, the mounting device holds the plated tube against this cradle surface, thus blocking the displacement of the tube and thus ensuring its rigid attachment with the spacers . This distal end surface preferably has a profile complementary to that of the tube.

Dans certains modes de réalisation, le tube possède une longueur supérieure à 2 m, voire supérieure à 3m. Le dispositif de montage proposé par le présent exposé est particulièrement utile lorsque le tube présente une telle longueur compte tenu du bras de levier important, et donc la démultiplication de la force de traction, que celle-ci entraîne.In some embodiments, the tube has a length greater than 2 m, or even greater than 3 m. The mounting device proposed by the present disclosure is particularly useful when the tube has such a length in view of the large lever arm, and therefore the reduction of the pulling force that it entails.

Dans certains modes de réalisation, le tube est creux. Ceci peut permettre de faire passer certains éléments à l'intérieur du tube. Le dispositif de montage proposé par le présent exposé est particulièrement utile dans ce cas puisque seule l'épaisseur du tube, réduite par rapport au diamètre du tube, permet l'accroche du dispositif de montage sur le tube : on comprend donc qu'une telle accroche est naturellement plus fragile et susceptible de se desserrer qu'une accroche dans un tube plein.In some embodiments, the tube is hollow. This may allow certain elements to be passed inside the tube. The mounting device proposed by the present disclosure is particularly useful in this case since only the thickness of the tube, reduced relative to the diameter of the tube, allows the attachment of the mounting device on the tube: it is therefore understood that such grip is naturally more fragile and likely to loosen than a hook in a solid tube.

Dans certains modes de réalisation, le tube loge un mécanisme de verrouillage du type à crémone. Il peut notamment s'agir d'un mécanisme de verrouillage à crémone décrit par la demanderesse dans la demande de brevet français FR 2 930 582 .In some embodiments, the tube houses a cremone type locking mechanism. It may in particular be a cremone lock mechanism described by the applicant in the application for French patent FR 2 930 582 .

Dans d'autres modes de réalisation, le tube est plein.In other embodiments, the tube is full.

Dans certains modes de réalisation, la poignée comprend au plus trois entretoises de fixation, de préférence au plus deux entretoises de fixation. Une telle configuration donne une impression d'ensemble plus légère et donc plus esthétique. Le dispositif de montage proposé par le présent exposé est particulièrement utile dans ce cas puisque la force de traction exercée par l'utilisateur n'est répartie que sur deux ou trois entretoises. En outre, cette configuration implique des bras de leviers importants entre les entretoises, placées de préférence à proximité des extrémités du tube, et la zone du tube au niveau de laquelle tirent les utilisateurs.In some embodiments, the handle comprises at most three attachment struts, preferably at most two attachment struts. Such a configuration gives a lighter overall impression and therefore more aesthetic. The mounting device proposed by this presentation is particularly useful in this case since the traction force exerted by the user is distributed over two or three spacers. In addition, this configuration involves large lever arms between the spacers, preferably placed near the ends of the tube, and the area of the tube at which users pull.

Le présent exposé concerne également une porte comprenant un panneau et au moins une poignée selon l'un quelconque des modes de réalisation précédents montée sur ledit panneau.The present disclosure also relates to a door comprising a panel and at least one handle according to any one of the preceding embodiments mounted on said panel.

Dans certains modes de réalisation, le panneau est réalisé en verre. Les portes en verres sont transparentes et esthétiques, ce qui les rend attractives pour les grands magasins notamment, mais elles sont lourdes et fragiles. Les poignées proposées par le présent exposées sont donc particulièrement adaptées à de telles portes en verre.In some embodiments, the panel is made of glass. The glass doors are transparent and aesthetic, which makes them attractive for department stores in particular, but they are heavy and fragile. The handles proposed by the present invention are therefore particularly suitable for such glass doors.

Dans certains modes de réalisation, au moins une entretoise de la poignée est montée sur le panneau à l'aide d'un accessoire de fixation du type à coupelles. Il peut notamment s'agit d'un accessoire de fixation tel que décrit par la demanderesse dans la demande de brevet français FR 2 964 430 . Un tel accessoire est particulièrement utile pour fixer solidement les poignées sur un panneau de verre sans le fragiliser. De même, il permet au panneau de verre de résister à des efforts de tractions importants.In some embodiments, at least one handle spacer is mounted to the panel using a cup-type attachment accessory. It may in particular be a fixing accessory as described by the applicant in the French patent application FR 2 964 430 . Such an accessory is particularly useful for securely attaching the handles to a glass panel without weakening it. Similarly, it allows the glass panel to withstand significant traction efforts.

Dans certains modes de réalisation, l'accessoire de fixation est muni de rondelles en aluminium intercalées entre chaque coupelle et le panneau. De telles rondelles en aluminium permettent d'atteindre des niveaux de serrages très importants entre les entretoises et le panneau, y compris lorsque celui-ci est en verre.In some embodiments, the attachment accessory is provided with aluminum washers interposed between each cup and the panel. Such aluminum washers can achieve very high levels of clamping between the spacers and the panel, including when it is glass.

DESCRIPTION DETAILLEE D'EXEMPLE(S) DE REALISATIONDETAILED DESCRIPTION OF EXAMPLE (S) OF REALIZATION

Afin de rendre plus concrète l'invention, un exemple de poignée est décrit en détail ci-après, en référence aux dessins annexés. Il est rappelé que l'invention ne se limite pas à cet exemple.In order to make the invention more concrete, an example of a handle is described in detail below, with reference to the accompanying drawings. It is recalled that the invention is not limited to this example.

La FIG 1 représente une porte 1 comprenant un panneau de verre 2 équipé sur chacune de ses faces d'une poignée 3 du type bâton. Chaque poignée 3 comprend un tube en inox 4, creux, s'étendant sur toute la hauteur du panneau 2, une pluralité d'entretoises de fixation 5, et une entretoise de serrure 6.The FIG 1 represents a door 1 comprising a glass panel 2 equipped on each of its faces with a handle 3 of the stick type. Each handle 3 comprises a hollow stainless steel tube 4 extending over the entire height of the panel 2, a plurality of fixing struts 5, and a lock spacer 6.

De préférence, chaque poignée ne comporte que deux entretoises de fixation 5, l'une prévue à proximité de l'extrémité supérieure du tube, à moins de 30 cm de l'extrémité supérieure par exemple, l'autre prévue à proximité de l'extrémité inférieure du tube, à moins de 30 cm de l'extrémité inférieure par exemple ; l'entretoise de serrure 6 est quant à elle prévue à une hauteur classique de serrure, par exemple entre 90 et 120 cm à partir de l'extrémité inférieure du tube. Pour les portes de très grande taille, dépassant 3 m par exemple, il est possible de prévoir une entretoise de fixation 5 supplémentaire entre l'entretoise de serrure 6 et l'entretoise de fixation 5 supérieure.Preferably, each handle has only two fixing struts 5, one provided near the upper end of the tube, less than 30 cm from the upper end, for example, the other provided near the lower end of the tube, less than 30 cm from the lower end, for example; the lock spacer 6 is in turn provided at a conventional lock height, for example between 90 and 120 cm from the lower end of the tube. For doors of very large size, exceeding 3 m for example, it is possible to provide an additional fixing spacer 5 between the lock spacer 6 and the upper fixing spacer 5.

De préférence en outre, le tube 4 et les entretoises 5, 6 sont cylindriques à base circulaire. Les entretoises de fixation 5 possèdent de préférence un diamètre d'environ 20 mm et le tube 4 possède un diamètre d'environ 25 mm. L'entretoise de serrure 6 possède quant à elle un diamètre d'environ 40 mm permettant de loger une serrure 61 et une partie d'un mécanisme de verrouillage. Ce mécanisme de verrouillage peut notamment comprendre des crémones s'étendant au sein du tube 4 de l'une des poignées 3 dont les extrémités sont munies de pênes commandables capables de faire saillie à partir des extrémités supérieure et inférieure du tube 4 pour coopérer avec des gâches et verrouiller ainsi la porte 1.Preferably furthermore, the tube 4 and the spacers 5, 6 are cylindrical with a circular base. The securing struts 5 preferably have a diameter of about 20 mm and the tube 4 has a diameter of about 25 mm. The lock spacer 6 has a diameter of about 40 mm for housing a lock 61 and part of a locking mechanism. This locking mechanism may in particular comprise cremones extending within the tube 4 of one of the handles 3 whose ends are provided with controllable bolts capable of protruding from the upper and lower ends of the tube 4 to cooperate with latches and thus lock the door 1.

La FIG 2 illustre plus précisément une entretoise de fixation 5 et son montage sur le tube 4. Chaque entretoise de fixation 5 comprend un cylindre 10 ouvert à son extrémité proximale et fermé à son extrémité distale par une paroi distale 11 en forme de berceau épousant la forme du tube 4 : ce cylindre 10 définit ainsi une cavité interne 12 de l'entretoise 5. Un orifice traversant 11a est en outre pratiqué au centre de la paroi distale 11.The FIG 2 illustrates more precisely a fixing spacer 5 and its mounting on the tube 4. Each fixing spacer 5 comprises a cylinder 10 open at its proximal end and closed at its end. distal by a distal wall 11 in the shape of a cradle conforming to the shape of the tube 4: this cylinder 10 thus defines an internal cavity 12 of the spacer 5. A through orifice 11a is furthermore made in the center of the distal wall 11.

Pour son montage sur le tube 4, l'entretoise 5 est plaquée contre le tube 4 à l'aide de sa paroi distale en berceau 11 et montée sur le tube 4 à l'aide d'un dispositif de montage 20. Ce dispositif de montage 20 comprend des lames ressorts 21 en forme de rondelles empilées dans la cavité 12 contre la surface interne 11b de la paroi distale 11. Le dispositif de montage 20 comprend en outre une douille 22 munie d'un épaulement 22a qui est passée au centre des lames ressorts 21, son épaulement 22a s'appuyant sur le sommet de l'empilement de lames ressorts 21. Enfin, une vis 23 est passée à travers la douille 22 et l'orifice 11a et vissée dans un orifice taraudé 24 de la paroi extérieure du tube 4 : la tête 23a de la vis 23 appuie alors sur l'épaulement 22a de la douille 22 et met en compression l'empilement de lames ressorts 21. On note en outre que le diamètre de l'orifice 11a est supérieur au diamètre de la vis 23 pour permettre à la vis 23 de s'incliner par rapport à l'axe de l'entretoise 5 ; l'empilement de ressort 21 permet de rappeler la vis 23 vers son inclinaison parallèle à l'axe de l'entretoise 5.For its mounting on the tube 4, the spacer 5 is pressed against the tube 4 by means of its distal cradle wall 11 and mounted on the tube 4 by means of a mounting device 20. This device mounting 20 comprises leaf springs 21 in the form of washers stacked in the cavity 12 against the inner surface 11b of the distal wall 11. The mounting device 20 further comprises a sleeve 22 provided with a shoulder 22a which is passed to the center of the spring blades 21, its shoulder 22a resting on the top of the stack of spring blades 21. Finally, a screw 23 is passed through the sleeve 22 and the orifice 11a and screwed into a threaded orifice 24 of the outer wall of the tube 4: the head 23a of the screw 23 then bears on the shoulder 22a of the sleeve 22 and compresses the stack of spring blades 21. It is further noted that the diameter of the orifice 11a is greater than the diameter of the screw 23 to allow the screw 23 to bow relative to the axis of the spacer 5; the spring stack 21 makes it possible to return the screw 23 towards its inclination parallel to the axis of the spacer 5.

L'entretoise de fixation 5 est ainsi montée sur le tube 4 par l'intermédiaire de son dispositif de montage 20 et en particulier de l'empilement de lames ressorts 21 formant organe élastique.The fixing spacer 5 is thus mounted on the tube 4 via its mounting device 20 and in particular the stack of spring blades 21 forming elastic member.

L'entretoise de fixation 5 comprend en outre un accessoire de fixation 30 permettant son montage sur le panneau de verre 2. Cet accessoire de fixation 30 comprend, de part et d'autre du panneau de verre 2, disposées autour d'un trou traversant 31 pratiqué dans le panneau de verre 2, un couple de coupelles 32 dont les surfaces d'appui 32a, annulaires, sont appliquées contre le panneau 2 à distance du trou traversant 31 et par l'intermédiaire de rondelles en aluminium 33. Une vis de serrage 34 permet de rapprocher les coupelles 32 l'une par rapport à l'autre afin de comprimer le panneau de verre 2 entre leurs surfaces d'appui 32a, fixant ainsi l'accessoire de fixation 30 sur le panneau 2.The fixing spacer 5 further comprises an attachment accessory 30 for mounting it on the glass panel 2. This attachment accessory 30 comprises, on either side of the glass panel 2, arranged around a through hole 31 practiced in the glass panel 2, a pair of cups 32 whose bearing surfaces 32a, annular, are applied against the panel 2 at a distance from the through hole 31 and through aluminum washers 33. A screw Clamping 34 allows the cups 32 to be brought closer to each other in order to compress the glass panel 2 between their bearing surfaces 32a, thus fixing the attachment accessory 30 on the panel 2.

Le cylindre 10 de l'entretoise 5 est alors rapporté autour de l'accessoire de fixation 30 qui est reçu dans la cavité interne 12 de l'entretoise 5. Une vis de blocage 35 permet de bloquer la position du cylindre 10 sur l'accessoire de fixation 30. En procédant ainsi avec chaque entretoise de fixation 5, on aboutit à la fixation des poignées 3 sur le panneau 2.The cylinder 10 of the spacer 5 is then reported around the attachment accessory 30 which is received in the internal cavity 12 of the spacer 5. A locking screw 35 serves to block the position of the cylinder 10 on the attachment accessory 30. By doing so with each fixing spacer 5, it leads to the attachment of the handles 3 on the panel 2.

Dans le présent exemple, l'entretoise de serrure 6, qui présente un diamètre supérieur au tube 4, est montée différemment par rapport au tube 4. Contrairement au cas des entretoises de fixation 5 qui sont rapportées sur le tube 4, ici le tube 4 est reçu et bloqué dans un passage vertical 62 pratiqué dans l'entretoise de serrure 6.In the present example, the lock spacer 6, which has a diameter greater than the tube 4, is mounted differently relative to the tube 4. Unlike the case of the fixing struts 5 which are attached to the tube 4, here the tube 4 is received and blocked in a vertical passage 62 formed in the lock spacer 6.

Le fonctionnement du dispositif de montage 20 sous l'effet d'une force de traction va maintenant être décrit en référence aux FIG 2 et 3. La FIG 2 représente la situation lorsque la porte 1 n'oppose que peu de résistance et peut ainsi être manoeuvrée en n'exerçant qu'une faible force de traction sur le tube 4 de la poignée 2.The operation of the mounting device 20 under the effect of a pulling force will now be described with reference to FIG 2 and 3 . The FIG 2 represents the situation when the door 1 poses little resistance and can thus be operated by exerting only a low tensile force on the tube 4 of the handle 2.

Dans ce cas, l'utilisateur cherchant à ouvrir la porte saisit le tube 4 à hauteur de bras et tire sur le tube 4 exerçant ainsi une force de traction sur le tube : cette force engendre alors une force et un couple de traction sur le dispositif de montage de chaque entretoise de fixation 5.In this case, the user seeking to open the door grasps the tube 4 at arm height and pulls on the tube 4 thus exerting a pulling force on the tube: this force then generates a force and a traction torque on the device mounting of each fixing spacer 5.

Plus précisément, cette force de traction est exercée par la tête de vis 23a sur l'empilement de lames ressorts 21 par l'intermédiaire de la douille 22. Dans ce cas de figure, cette force est insuffisante pour vaincre la force de rappel de l'empilement des lames ressorts 21 de telle sorte que ce dernier se comporte comme un bloc rigide transmettant directement la force de traction au cylindre 10 qui la transmet au panneau de porte 2 via l'accessoire de fixation 30 : on aboutit ainsi à l'ouverture de la porte. Dans ce cas, le couple de traction exercé au niveau de la vis 23 et du taraudage de l'orifice 24 n'est pas suffisant pour desserrer la vis 23 ni pour endommager le taraudage.More specifically, this traction force is exerted by the screw head 23a on the stack of leaf springs 21 through the sleeve 22. In this case, this force is insufficient to overcome the restoring force of the spring. stacking the spring blades 21 so that the latter behaves like a rigid block directly transmitting the traction force to the cylinder 10 which transmits it to the door panel 2 via the attachment accessory 30: this leads to the opening Door. In this case, the traction torque exerted at the screw 23 and the tapping of the orifice 24 is not sufficient to loosen the screw 23 nor to damage the tapping.

La FIG 3 représente quant à elle la situation lorsque la porte 1 oppose une résistance plus importante à l'ouverture, en particulier lorsqu'elle frotte au sol ou lorsque son pivot est endommagé ou mal lubrifié. Une force de traction plus importante est alors nécessaire pour permettre son ouverture.The FIG 3 represents the situation when the door 1 opposes a greater resistance to opening, especially when it rubs on the ground or when its pivot is damaged or poorly lubricated. A greater traction force is then necessary to allow its opening.

Dans ce cas, lorsque l'utilisateur tire sur le tube 4, il exerce une force de traction plus importante sur le tube. Compte tenu du bras de levier séparant la main de l'utilisateur des entretoises de fixation 5, et plus précisément du bord extérieur des entretoises 5 (le bord supérieur sur la FIG 3) qui constitue un pivot, cette force de traction génère un couple important au niveau de la vis 23 du dispositif de montage 20 qui serait normalement suffisant pour desserrer la vis 23 du taraudage 24 si la vis était bloquée en position dans l'entretoise 5.In this case, when the user pulls on the tube 4, he exerts a greater traction force on the tube. In view of the lever arm separating the user's hand from the fixing struts 5, and more specifically from the outer edge of the struts 5 (the upper edge on the FIG 3 ) which constitutes a pivot, this traction force generates a large torque at the screw 23 of the mounting device 20 which would normally be sufficient to loosen the screw 23 of the tapping 24 if the screw was locked in position in the spacer 5.

Toutefois, la force de traction exercée sur l'empilement de lames ressorts 21 est dans ce cas suffisant pour contrer la force de rappel de l'empilement 21 : la vis 23 peut alors bouger au sein du dispositif de montage 20 en translation ainsi qu'en rotation en fonction des efforts exercés. Dès lors, le tube 4 peut décoller de la paroi distale en berceau 11 de l'entretoise 5 et s'incliner par rapport à l'entretoise 5.However, the tensile force exerted on the stack of leaf springs 21 is in this case sufficient to counter the restoring force of the stack 21: the screw 23 can then move within the translation device 20 in translation as well as in rotation according to the exerted forces. As a result, the tube 4 can take off from the distal cradle wall 11 of the spacer 5 and tilt relative to the spacer 5.

Ainsi, lorsque l'utilisateur exerce une force de traction importante sur le tube 4 (la zone du tube saisie par l'utilisateur est située en direction du bas de la FIG 3), au moins la partie intérieure de l'empilement de lames ressorts 21 se comprime pour permettre à la vis 23 de s'incliner et au tube de se fléchir et de se courber entre les deux entretoises situées de part et d'autre de la zone du tube 4 saisie par l'utilisateur.Thus, when the user exerts a large traction force on the tube 4 (the zone of the tube entered by the user is located towards the bottom of the FIG 3 ), at least the inner portion of the stack of spring blades 21 is compressed to allow the screw 23 to tilt and the tube to bend and bend between the two spacers located on either side of the zone of the tube 4 entered by the user.

De cette manière, la vis 23 reste perpendiculaire au tube 4 de telle sorte qu'un couple nul ou pratiquement nul s'exerce sur le taraudage de l'orifice 24 : le risque de desserrement de la vis 23 est ainsi fortement réduit.In this way, the screw 23 remains perpendicular to the tube 4 so that a zero or virtually zero torque is exerted on the tapping of the orifice 24: the risk of loosening the screw 23 is thus greatly reduced.

Néanmoins, lorsqu'un équilibre est trouvé entre la force de traction exercée, la force de rappel de l'empilement de lames ressorts 21 et la force de rappel élastique du tube courbé 4, une composante axiale subsiste et se propage à travers le cylindre 10 et l'accessoire de fixation 30 pour ouvrir la porte 1.Nevertheless, when an equilibrium is found between the traction force exerted, the restoring force of the stack of leaf springs 21 and the elastic restoring force of the curved tube 4, an axial component remains and propagates through the cylinder 10 and the attachment accessory 30 to open the door 1.

Le déplacement et la flexion du tube 4 de la poignée 3 sont suffisamment faibles pour qu'ils ne soient pas gênants pour l'utilisateur. Lorsque l'utilisateur relâche le tube 4, l'élasticité du tube 4 et la force de rappel de l'empilement de lames ressorts 21 ramène le tube dans une position rectiligne rigidement maintenue contre les surfaces en berceau 11 des entretoises de fixation 5.The displacement and bending of the tube 4 of the handle 3 are sufficiently small so that they are not troublesome for the user. When the user releases the tube 4, the elasticity of the tube 4 and the restoring force of the stack of spring blades 21 brings the tube back into a rectilinear position rigidly held against the cradle surfaces 11 of the fixing struts 5.

La force seuil à partir de laquelle l'empilement de lames ressorts 21 commence à se comprimer est choisie en fonction de la résistance mécanique de la fixation de la vis 23 sur le tube 4. Dans le présent exemple, elle est fixée à environ 350 N.The threshold force from which the stack of leaf springs 21 begins to compress is chosen as a function of the mechanical strength of the attachment of the screw 23 to the tube 4. In the present example, it is set at about 350 N .

On note en outre que la présente description détaillée n'a considéré que le cas où l'utilisateur tirait sur la poignée pour ouvrir la porte. Toutefois, le cas où la porte doit être poussée plutôt que tirée est tout à fait analogue. En effet, lorsque l'utilisateur exerce une force de poussée sur le tube 4, une partie de cette dernière est transformée en une force de traction au niveau du dispositif de montage des entretoises de fixation 5 : le bord intérieur de l'entretoise 5 constitue en effet un pivot qui, en raison de l'effet de levier, inverse la direction de la force. Le fonctionnement du dispositif de montage 20 est alors complètement analogue si ce n'est que la vis 23 s'incline cette fois vers l'intérieur et que le tube 4 se courbe cette fois en direction du panneau 2.It is further noted that the present detailed description only considered the case where the user pulled on the handle to open the door. However, the case where the door must be pushed rather than pulled is quite similar. Indeed, when the user exerts a thrust force on the tube 4, part of the latter is transformed into a tensile force at the mounting device of the fastening struts 5: the inner edge of the spacer 5 constitutes indeed a pivot which, because of the leverage effect, reverses the direction of the force. The operation of the mounting device 20 is then completely similar except that the screw 23 tilts this time inwards and that the tube 4 bends this time towards the panel 2.
