Description

L'invention concerne un dispositif de sécurité pour bâtiment, et plus précisément pour bâtiment comportant au moins une paroi, par exemple une façade, au moins partiellement vitrée, constituée essentiellement d'une structure rigide, de préférence métallique, à laquelle un ou généralement plusieurs panneaux vitrés sont associés, de façon que la structure ne soit pas apparente.The invention relates to a security device for buildings, and more specifically for buildings comprising at least one wall, for example a facade, at least partially glazed, essentially consisting of a rigid structure, preferably metallic, to which one or generally several glass panels are associated, so that the structure is not visible.

Pour plus de simplicité et de clarté, on ne considérera le cas que d'un panneau vitré, étant entendu dans la pratique, que la façade d'un bâtiment est généra­lement constituée d'une multitude de panneaux vitrés. Un dispositif de sécurité selon l'invention sera avantageusement prévu pour chacun des panneaux vitrés de façade ou autre paroi du bâtiment.For simplicity and clarity, we will only consider the case of a glazed panel, it being understood in practice that the facade of a building is generally made up of a multitude of glazed panels. A safety device according to the invention will advantageously be provided for each of the front glass panels or other wall of the building.

On connait déjà des bâtiments dont au moins une paroi ou façade est partiellement ou entièrement vitrée. La structure rigide, généralement métallique, du bâtiment définit au moins un châssis sur lequel est associé rigidement un panneau vitré par des moyens d'association par collage simple, sans parclose, avec interposition de joints d'étanchéité et de fixation entre la surface intérieure du panneau et la structure. Ces moyens d'association du panneau au châssis de la structure peuvent être défaillants. Par exemple, ils peuvent se détériorer au bout d'un certain temps, notamment sous l'effet des intempéries. Dans ce cas, le panneau vitré se détache de la structure et chute. Or, une telle chute peut provoquer des dégâts considérables sur des objets ou personnes situés au pied du bâtiment.We already know buildings with at least one wall or facade is partially or fully glazed. The rigid, generally metallic, structure of the building defines at least one frame on which a glazed panel is rigidly associated by means of association by simple bonding, without glazing beads, with interposition of seals and fixing between the interior surface of the panel and structure. These means of association of the panel with the chassis of the structure may be faulty. For example, they can deteriorate after a certain time, in particular under the effect of bad weather. In this case, the glass panel detaches from the structure and falls. However, such a fall can cause considerable damage to objects or people located at the foot of the building.

On connaît déjà de la demande de brevet européen 0 251 834 un dispositif de sécurité pour bâtiment à paroi et/ou façade vitrée comportant au moins un panneau vitré, chaque panneau vitré pouvant être constitué d'une ou plusieurs vitres associées au châssis de la structure rigide du bâtiment par des moyens d'association rigide normalement actifs en permanence, le dispositif de sécurité comportant au moins une pièce de maintien en place au voisinage du châssis et/ou de destruction du vitrage du panneau, cette pièce coopérant avec au moins une portion de la périphérie de la vitre extérieure du panneau en vue de son maintien et/ou de sa destruction en cas de défaillance des moyens d'asso­ciation des vitres constituant le vitrage du panneau les unes aux autres et/ou en cas de défaillance des moyens d'association du panneau au châssis, dans le but d'éviter que le panneau ou une partie de son vitrage ne tombe en un seul bloc. De la sorte, si le panneau vient à se détacher de la structure, il est soit maintenu, soit, si le maintien n'est pas possible, brisé et réduit en morceaux avant de chuter. Les conséquences de la chute du panneau sont alors bénignes car la multitude de petits morceaux résultant du bris du panneau est beaucoup moins dévastatrice qu'un vitrage monobloc.A safety device for a building with a glass wall and / or facade comprising at least one glazed panel is already known from European patent application 0 251 834, each glazed panel being able to consist of one or more panes associated with the frame of the structure. rigid of the building by rigid association means normally permanently active, the safety device comprising at least one holding part in place in the vicinity of the chassis and / or destruction of the panel glazing, this part cooperating with at least a portion of the periphery of the outer glass of the panel with a view to maintaining and / or destroying it in the event of failure of the means of association of the panes constituting the glazing of the panel to each other and / or in the event of failure of the means of association of the panel with the frame, with the aim of preventing the panel or part of its glazing from falling in one piece. In this way, if the panel comes to detach from the structure, it is either maintained, or, if the maintenance is not possible, broken and reduced to pieces before falling. The consequences of the fall of the panel are then benign because the multitude of small pieces resulting from the breakage of the panel is much less devastating than one-piece glazing.

On sait également qu'un vitrage associé par collage au châssis d'une structure rigide doit être susceptible de pouvoir bouger légèrement par rapport à la struc­ture rigide, notamment sous l'effet du vent, ou des phénomènes thermiques. Pour cette raison, il n'est pas possible en général de fixer rigidement et direc­tement une telle pièce de sécurité au châssis de la structure rigide. En effet, dans un tel cas, la pièce ne pourrait pas se déplacer avec le vitrage, et serait susceptible de détruire ce vitrage alors qu'aucun problème n'est apparu dans les différents joints d'association. De plus, pour des raisons liées au montage du panneau sur la structure, il est préférable voire indispensable que de telles pièces de sécurité fassent partie intégrante du panneau et lui soient associées rigidement.It is also known that glazing associated by bonding to the frame of a rigid structure must be capable of being able to move slightly relative to the rigid structure, in particular under the effect of wind, or thermal phenomena. For this reason, it is not generally possible to rigidly and directly fix such a safety piece to the chassis of the rigid structure. Indeed, in such a case, the part could not move with the glazing, and would be likely to destroy this glazing while no problem has appeared in the various association joints. In addition, for reasons related to the mounting of the panel on the structure, it is preferable or even essential that such safety parts form an integral part of the panel and be rigidly associated with it.

Pour ce faire, la demande de brevet européen 0 251 834 décrit une possibilité de fixation des pièces de sécurité à un panneau à vitrage multiple, grâce à une protubérance de la pièce qui vient pénétrer dans le joint périphérique du panneau entre la vitre intérieure et la vitre extérieure.To do this, European patent application 0 251 834 describes a possibility of fixing the security parts to a panel with multiple glazing, thanks to a protuberance of the part which comes to penetrate the peripheral joint of the panel between the interior glass and the exterior glass.

Cependant, par rapport au mode de réalisation à vitrage multiple décrit dans la demande de brevet européen 0 251 834, se pose le problème du montage d'une telle pièce de sécurité sur le panneau vitré lorsque ce panneau ne comporte qu'une seule vitre. En effet, dans le cas d'un vitrage simple, il n'existe pas de joint d'association permettant une fixation aussi bonne de la pièce que dans le cas d'un vitrage multiple. La solution évidente permettant la fixation de la pièce à la vitre d'un panneau à vitrage simple, consiste à coller simplement une pièce similaire à celle décrite dans la demande de brevet européen 0 251 834, sur la partie de vitrage avec laquelle elle coopère. En particulier, lorsque l'on prévoit un joint d'amortissement entre la pièce métallique et la vitre, ce joint peut être réalisé sous forme adhésive et porter lui-même la pièce.However, compared with the embodiment with multiple glazing described in European patent application 0 251 834, there is the problem of mounting such a security piece on the glazed panel when this panel has only one window. In fact, in the case of single glazing, there is no association joint allowing the part to be fixed as well as in the case of multiple glazing. The obvious solution allowing the part to be fixed to the glass of a single glazed panel, consists in simply gluing a part similar to that described in European patent application 0 251 834, on the part of glazing with which it cooperates. In particular, when a damping joint is provided between the metal part and the glass, this joint can be produced in adhesive form and carry the part itself.

Cependant, il a été mis en évidence qu'une telle fixation n'est pas suffisante. En effet, les moyens d'association prévus par ailleurs de la pièce au châssis ne sont pas dans le même plan que la partie de la pièce qui coopère avec la vitre. Dès lors, lorsque la pièce de sécurité rentre en fonctionnement, il se produit un couple de basculement de cette pièce autour du bord de la vitre, couple qui a tendance à décoller la pièce de la vitre et à la rendre ainsi totale­ment inefficace. De plus, il s'est avéré que le simple collage de la pièce sur la vitre ne procure pas une fixation suffisamment solide et fiable car lors de l'installation du panneau vitré sur la structure, ce panneau subi de nombreuses manipulations et il arrive bien souvent que la pièce de sécurité vienne à se décoller.However, it has been demonstrated that such fixation is not sufficient. In fact, the means of association provided elsewhere for the part with the frame are not in the same plane as the part of the part which cooperates with the window. Therefore, when the safety part returns to operation, there is a tilting torque of this part around the edge of the glass, a torque which tends to detach the part from the glass and thus make it completely ineffective. In addition, it turned out that the simple bonding of the part on the glass does not provide a sufficiently solid and reliable fixing because during the installation of the glass panel on the structure, this panel undergoes many manipulations and it happens well often the security piece comes off.

L'invention vise donc à remédier à ces inconvénients et a pour objet un dispositif de sécurité destiné à un panneau vitré constitué d'une vitre unique, et qui puisse être associé rigidement et solidement à cette vitre, et ce de façon simple et économique. Un autre objet de l'invention est de proposer un tel dispositif de sécurité qui soit compatible avec la plupart des modes de fixation du panneau à la structure, c'est-à-dire qui ne nuise pas à l'intégrité des joints d'étanchéité et d'association du panneau à la structure. Un autre objet de l'invention est de proposer un tel dispositif de sécurité qui puisse remplir pour un vitrage simple les mêmes fonctions et avec la même efficacité que ceux connus pour les vitrages multiples, notamment de la demande de brevet européen 0 251 834.The invention therefore aims to remedy these drawbacks and relates to a safety device intended for a glazed panel consisting of a single pane, which can be rigidly and securely associated with this pane, in a simple and economical manner. Another object of the invention is to provide such a safety device which is compatible with most of the methods of fixing the panel to the structure, that is to say which does not harm the integrity of the joints of sealing and association of the panel with the structure. Another object of the invention is to propose such a safety device which can fulfill the same functions and with the same efficiency for simple glazing as those known for multiple glazing, in particular from European patent application 0 251 834.

Plus précisément, l'invention vise à proposer un dispositif de sécurité pour vitrage extérieur collé à une seule vitre, qui assure le maitien en place du panneau vitré en cas de défaillance des moyens de fixation du panneau à la structure, ou qui, dans le cas où le vitrage est en verre trempé, assure le bris de ce vitrage si son maintien au voisinnage de la structure n'est pas possible ; ce dispositif de sécurité étant inactif, soumis à aucune contrainte, ne s'usant pas, ne travaillant pas et n'affectant donc pas la durée de vie du vitrage, lorsque les moyens de fixation sont normalement actifs et en bon état ; ce dispositif de sécurité ne rentrant en fonctionnement que lorsque les moyens de fixation ont subi une détérioration inacceptable ; ce dispositif de sécurité étant invisible de l'extérieur ; ce dispositif de sécurité pouvant être monté solidaire de chaque panneau vitré de sorte que les panneaux arrivent sur le chantier munis de tels dispositifs de sécurité.More specifically, the invention aims to propose a safety device for exterior glazing bonded to a single window, which ensures the maintenance in place of the glazed panel in the event of failure of the means of fixing the panel to the structure, or which, in the case where the glazing is made of tempered glass, ensures breakage of this glazing if its maintenance in the vicinity of the structure is not possible; this safety device being inactive, subject to any constraint, not wearing out, not working and therefore not affecting the life of the glazing, when the fixing means are normally active and in good condition; this safety device returning to operation only when the fixing means have suffered unacceptable deterioration; this safety device being invisible from the outside; this safety device can be mounted integral with each glazed panel so that the panels arrive on the site provided with such safety devices.

Pour ce faire, l'invention propose un dispositif de sécurité invisible pour bâtiment à paroi et/ou façade vitrée comportant au moins un panneau vitré, chaque panneau vitré étant constitué d'une vitre unique associée au châssis de la struc­ture rigide du bâtiment par des moyens d'association normalement actifs en permanence, le dispositif de sécurité comportant au moins une pièce de maintien en place au voisinage du châssis et/ou de destruction du vitrage du panneau en cas de défaillance des moyens d'association du panneau au châssis, une telle pièce coopérant avec une portion de la périphérie de la vitre, caractérisé en ce que chaque pièce comporte une patte d'association de cette pièce à la face interne de la vitre, cette patte s'étendant au moins sensiblement parallèlement à et en regard d'une portion périphérique de cette face interne de sorte qu'elle peut y être associée par collage ou équivalent. Une pièce de sécurité selon l'invention est constituée d'une portion de profilé et, selon une autre caracté­ristique de l'invention, vue en section droite transversale perpendiculaire au chant correspondant de la vitre, une pièce du dispositif de sécurité est constituée, de l'extérieur vers l'intérieur, d'une branche externe coopérant avec une portion de la face externe de la vitre ; d'une branche intermédiaire coopérant avec le châssis par l'intermédiaire d'éléments appropriés, et s'étendant au moins sensiblement perpendiculairement au plan P de la vitre le long d'une portion du chant de cette vitre ; et de la patte d'association qui s'étend au moins sensiblement parallèlement au plan P de la vitre en direction de la partie centrale de la vitre, à partir de l'extrémité interne de la branche intermédiaire, la pièce ayant sensiblement la forme d'un U ou d'un pseudo-U de sorte qu'elle peut s'emboîter par coincement sur la vitre.To do this, the invention provides an invisible security device for a building with a glass wall and / or facade comprising at least one glass panel, each glass panel consisting of a single window associated with the chassis of the rigid structure of the building by means of association normally permanently active, the safety device comprising at least one piece for holding in place in the vicinity of the frame and / or for destroying the glazing of the panel in the event of failure of the means for associating the panel with the frame, a such a part cooperating with a portion of the periphery of the glass, characterized in that each part comprises a tab for associating this part with the internal face of the glass, this tab extending at least substantially parallel to and facing d 'a peripheral portion of this internal face so that it can be associated with it by bonding or equivalent. A security part according to the invention consists of a section portion and, according to another characteristic of the invention, seen in cross section perpendicular to the corresponding edge of the window, a part of the security device is made, of outside towards inside, of an external branch cooperating with a portion of the external face of the window; an intermediate branch cooperating with the frame by means of suitable elements, and extending at least substantially perpendicular to the plane P of the window pane along a portion of the edge of this pane; and of the association tab which extends at least substantially parallel to the plane P of the glass in the direction of the central part of the glass, from the internal end of the intermediate branch, the part having substantially the shape of 'a U or a pseudo-U so that it can fit together by wedging on the glass.

L'invention concerne également un panneau de façade vitré à une seule vitre caractérisé en ce qu'il comporte un dispositif de sécurité selon l'invention consti­tué d'au moins une pièce qui lui est associée par collage ou équivalent sur une portion de la face interne de la vitre. L'invention concerne enfin un procédé d'association d'un dispositif de sécurité selon l'invention à un panneau vitré constitué d'une vitre unique, caractérisé en ce que l'on place un fond de joint, notamment en mousse polyuréthane ou autre, localement à l'extrême périphérie de la face interne de la vitre, à l'emplacement où une pièce doit être fixée, on emboîte ensuite la pièce en coinçant le fond de joint entre la patte et la vitre, puis on dépose un joint adhésif, notamment en silicone, à recouvrement vers l'intérieur du fond de joint, entre la partie extrême libre de la patte et la vitre.The invention also relates to a glazed facade panel with a single pane characterized in that it comprises a safety device according to the invention consisting of at least one part which is associated with it by bonding or equivalent on a portion of the face internal of the glass. Finally, the invention relates to a method of associating a safety device according to the invention with a glazed panel consisting of a single pane, characterized in that a seal bottom is placed, in particular in polyurethane foam or other, locally at the extreme periphery of the internal face of the glass, at the location where a part must be fixed, the part is then fitted by wedging the bottom of the joint between the tab and the glass, then depositing an adhesive seal, in particular silicone, overlapping towards the inside of the seal bottom, between the free end of the tab and the glass.

L'invention concerne un dispositif de sécurité invisible pour bâtiment à paroi et/ou façade vitrée. Cette paroi ou façade est essentiellement constituée d'une structure 1 rigide, généralement métallique, et d'une pluralité de panneaux vitrés 2. Cette paroi ou façade sépare un espace intérieur 21 d'un espace exté­rieur 22. Pour plus de clarté dans la suite, on ne s'intéressera qu'à un de ces panneaux 2 et on supposera qu'il est plan et s'étend sensiblement verticalement. Ces hypothèses ne sont nullement limitatives et l'invention est évidemment applicable à toutes formes et dispositions de panneaux vitrés 2 à une seule vitre.The invention relates to an invisible security device for a building with a glass wall and / or facade. This wall or facade essentially consists of a rigid structure, generally metallic, and a plurality of glazed panels 2. This wall or facade separates an interior space 21 from an exterior space 22. For greater clarity in the following. , we will only be interested in one of these panels 2 and we will assume that it is planar and extends substantially vertically. These hypotheses are in no way limiting and the invention is obviously applicable to all forms and arrangements of glazed panels 2 with a single pane.

La structure 1 définit un châssis 3 sur lequel le panneau 2 est associé par des moyens 4 d'association qui sont des moyens de collage sans parclose, et compor­tent un ou plusieurs joints d'association et/ou d'étanchéité 4, constitués par exemple de silicone à haut module d'élasticité. De même, les différents châssis 3 correspondant à chacun des panneaux 2 de la structure 1 sont associés les uns aux autres de façon connue par des moyens d'association et d'étanchéité constitués par exemple d'un joint de silicone et d'un fond de joint. Les joints d'étanchéité sont par exemple des joints en polymère, notamment en silicone.The structure 1 defines a frame 3 on which the panel 2 is associated by association means 4 which are bonding means without glazing beads, and comprise one or more association and / or sealing joints 4, constituted for example silicone with high elasticity modulus. Similarly, the different frames 3 corresponding to each of the panels 2 of the structure 1 are associated with each other in a known manner by means of association and sealing consisting for example of a silicone seal and a bottom seal. The seals are for example seals made of polymer, in particular silicone.

L'invention concerne un dispositif de sécurité selon l'invention pour bâtiment à paroi et/ou façade vitrée comportant au moins un panneau vitré 2, chaque panneau vitré 2 étant constitué d'une vitre unique 5 associée au châssis 3 de la structure rigide 1 du bâtiment par des moyens 4 d'association normalement actifs en permanence. Le dispositif de sécurité selon l'invention comporte au moins une pièce 6 de maintien en place au voisinage du châssis 3 et/ou de destruction du vitrage du panneau 2 en cas de défaillance des moyens 4 d'asso­ciation du panneau 2 au châssis 3. Une telle pièce 6 est constituée d'une portion de profilé, et coopère avec au moins une portion 7 de la périphérie de la face externe 8 de la vitre 5. Le fonctionnement général d'une telle pièce 6 de main­tien en place au voisinage du châssis 3 et/ou de destruction du vitrage du panneau 2 en cas de défaillance des moyens 4 d'association du panneau 2 au châssis 3, est connu de la demande de brevet européen 0 251 834 dont l'enseignement est incorporé à la présente description. Ainsi, une telle pièce est conçue généra­lement de telle façon qu'elle puisse remplir deux fonctions successives : un première fonction de maintien en place de la vitre 5 du panneau 2 en cas de défaillance légère, progressive ou partielle des moyens 4 d'association du panneau 2 au châssis 3, et, dans le cas où le vitrage est en verre trempé ou équivalent, une seconde fonction de destruction de la vitre 5 du panneau 2 en cas de défail­lance subite complète des moyens 4 d'association du panneau 2 au châssis 3 et lorsque la chute de cette vitre 5 est inévitable. Lorsque la chute de la vitre 5 est inévitable, la pièce 6 permet de provoquer le bris de la vitre 5 avant sa chute, et ce afin d'éviter que cette vitre 5 ne tombe en un seul bloc.The invention relates to a safety device according to the invention for a building with a glass wall and / or facade comprising at least one glass panel 2, each glazed panel 2 consisting of a single window 5 associated with the frame 3 of the rigid structure 1 of the building by means 4 of association normally active permanently. The safety device according to the invention comprises at least one piece 6 for holding in place in the vicinity of the frame 3 and / or for destroying the glazing of the panel 2 in the event of failure of the means 4 for associating the panel 2 with the frame 3. Such a part 6 consists of a section portion, and cooperates with at least one portion 7 of the periphery of the external face 8 of the window 5. The general operation of such a part 6 for holding in place in the vicinity of the frame 3 and / or destruction of the glazing of the panel 2 in the event of failure of the means 4 for associating the panel 2 with the frame 3, is known from European patent application 0 251 834, the teaching of which is incorporated into the present description . Thus, such a part is generally designed in such a way that it can fulfill two successive functions: a first function of holding the window 5 of the panel 2 in place in the event of a slight, progressive or partial failure of the means 4 for associating the panel 2 to the frame 3, and, in the case where the glazing is made of tempered glass or equivalent, a second function of destruction of the window 5 of the panel 2 in the event of a sudden complete failure of the means 4 for associating the panel 2 with the frame 3 and when the fall of this window 5 is inevitable. When the fall of the window 5 is inevitable, the part 6 makes it possible to cause the window 5 to break before it falls, in order to prevent this window 5 from falling in one piece.

Selon l'invention, chaque pièce 6 comporte une patte 11 d'association de cette pièce 6 à la face interne 9 de la vitre 5, cette patte 11 s'étendant au moins sensiblement parallèlement à et en regard d'une portion périphérique 10 de cette face interne 9 de la vitre 5, de sorte qu'elle peut y être associée par collage ou équivalent.According to the invention, each piece 6 has a tab 11 for associating this piece 6 with the internal face 9 of the window 5, this tab 11 extending at least substantially parallel to and facing a peripheral portion 10 of this internal face 9 of the window 5, so that it can be associated with it by bonding or the like.

Une pièce 6 ne s'étend pas longitudinalement sur tout un chant de la vitre 5, mais seulement sur une portion périphérique d'un chant ou d'un coin de la vitre 5.A part 6 does not extend longitudinally over an entire edge of the window 5, but only over a peripheral portion of an edge or of a corner of the window 5.

Vue en section droite transversale perpendiculaire au chant 12 correspondant en regard de la vitre 5, de l'extérieur 22 vers l'intérieur 21, c'est-à-dire de la gauche vers la droite sur la figure 2, une pièce 6 profilée est constituée d'une branche externe 13 coopérant avec une portion 7 de la face externe 8 de la vitre 5 ; d'une branche intermédiaire 14 coopérant avec le châssis 3 par l'intermédiaire d'éléments 15, 16 appropriés, cette branche intermédiaire 14 s'étendant au moins sensiblement perpendiculairement au plan P de la vitre 5 le long d'une portion du chant 12 de cette vitre 5 ; et de la patte 11 d'asso­ ciation qui s'étend au moins sensiblement parallèlement au plan P de la vitre 5 en direction de la partie centrale de cette vitre 5 à partir de l'extrémité interne 17 de la branche intermédiaire 14. La pièce 6 profilée a donc, en section droite transversale, sensiblement la forme d'un U, ou d'un pseudo-U selon la forme donnée à la branche externe, de sorte qu'elle peut s'emboîter par coince­ment sur la vitre 5 en recouvrant une portion correspondante du chant 12.Cross-section view perpendicular to the corresponding edge 12 opposite the window 5, from the outside 22 to the inside 21, that is to say from the left to the right in FIG. 2, a profiled part 6 consists of an outer branch 13 cooperating with a portion 7 of the outer face 8 of the window 5; an intermediate branch 14 cooperating with the chassis 3 by means of suitable elements 15, 16, this intermediate branch 14 extending at least substantially perpendicular to the plane P of the window 5 along a portion of the edge 12 of this window 5; and paw 11 of asso ciation which extends at least substantially parallel to the plane P of the window 5 in the direction of the central part of this window 5 from the inner end 17 of the intermediate branch 14. The profiled part 6 therefore has, in cross section transverse, substantially the shape of a U, or of a pseudo-U depending on the shape given to the external branch, so that it can fit together by jamming on the window 5 by covering a corresponding portion of the edge 12.

La branche intermédiaire 14 a une longueur (dans le sens perpendiculaire du plan P de la vitre 5) suffisante pour permettre l'emboîtement de la pièce 6 sur le chant 12 de la vitre 5. Selon l'invention, la branche intermédiaire 14 a cependant une longueur telle qu'elle permet d'interposer un ou plusieurs joints appropriés 18, 19 et/ou 20 entre la patte 11 et la face interne 9 en regard de la vitre 5 et/ou entre la branche externe 13 et la face externe 8 en regard de la vitre 5.The intermediate branch 14 has a length (in the perpendicular direction of the plane P of the window 5) sufficient to allow the fitting of the part 6 on the edge 12 of the window 5. According to the invention, the intermediate branch 14 has however a length such that it allows one or more suitable seals 18, 19 and / or 20 to be interposed between the tab 11 and the internal face 9 facing the window 5 and / or between the external branch 13 and the external face 8 next to the window 5.

En effet, il est souhaitable de pouvoir interposer entre la branche externe 13 et la face externe 8 de la vitre 5 un joint d'amortissement 20. De plus, l'asso­ciation rigide de la patte 11 à la face interne 9 en regard de la vitre 5 doit pouvoir être réalisée grâce à des joints 18, 19 interposés entre cette patte 11 et la vitre 5 comme cela sera décrit plus précisément ultérieurement.Indeed, it is desirable to be able to interpose between the external branch 13 and the external face 8 of the window 5 a damping joint 20. In addition, the rigid association of the tab 11 with the internal face 9 opposite the window 5 must be able to be produced by seals 18, 19 interposed between this tab 11 and the window 5 as will be described more precisely later.

Selon l'invention, la branche intermédiaire 14 a une longueur telle que l'épaisseur totale formée par les joints 18, 19 interposés la patte 11, vers l'intérieur 21 à partir de la vitre 5, est inférieure à l'épaisseur selon la même direction des moyens 4 d'association de la vitre 5 au châssis 3, c'est-à-dire est inférieure à la distance séparant la face interne 9 de la vitre 5 du châssis 3 en regard. Selon l'invention, cette longueur de la branche intermédiaire 14 est telle qu'un jeu 23 est laissé entre la patte 11 et le châssis 3 lorsque la vitre 5 est associée rigidement à ce châssis 3. Le jeu 23 est prévu pour être de même ordre de grandeur que le jeu 32 qui est aussi prévu entre la branche intermédiaire 14 et le châssis 3. Le jeu 23 est notamment d'au moins 2 mm. Une pièce 6 n'est donc pas associée directement au châssis 3, mais constitue au contraire grâce au jeu 23 des moyens de détection d'un déplacement transversal intempestif de la vitre 5 perpendiculairement à son plan. La détection par la pièce 6 a lieu par contact de la patte 11 de cette pièce 6 avec le châssis après résorption du jeu 23, le châssis 3 formant butée transversale pour cette patte 11.According to the invention, the intermediate branch 14 has a length such that the total thickness formed by the seals 18, 19 interposed the tab 11, inwards 21 from the window 5, is less than the thickness according to the same direction of the means 4 for associating the window 5 with the frame 3, that is to say is less than the distance separating the internal face 9 of the window 5 from the facing frame 3. According to the invention, this length of the intermediate branch 14 is such that a clearance 23 is left between the tab 11 and the frame 3 when the window pane 5 is rigidly associated with this frame 3. The clearance 23 is provided to be the same order of magnitude as the clearance 32 which is also provided between the intermediate branch 14 and the chassis 3. The clearance 23 is in particular at least 2 mm. A part 6 is therefore not directly associated with the chassis 3, but on the contrary constitutes, thanks to the clearance 23, means for detecting an inadvertent transverse movement of the window 5 perpendicular to its plane. The detection by the part 6 takes place by contact of the tab 11 of this part 6 with the chassis after clearance of the clearance 23, the chassis 3 forming a transverse stop for this tab 11.

Selon l'invention, une pièce 6 est formée d'un profilé métallique, notamment en aluminium, s'étendant le long d'une portion du chant 12 de la vitre 5 au voisinage d'un coin 24 de la vitre 5. La longueur de ce profilé métallique est par exemple comprise entre 1 et 20 cm, notamment de l'ordre de 10 cm.According to the invention, a part 6 is formed from a metal profile, in particular aluminum, extending along a portion of the edge 12 of the window 5 in the vicinity of a corner 24 of the window 5. The length of this metal profile is for example between 1 and 20 cm, in particular of the order of 10 cm.

Selon l'invention, la branche externe 13 est inclinée vers l'extérieur 22 pour pouvoir coopérer avec une portion 7 de la face externe 8 de la vitre 5 qui est biseautée avec la même inclinaison. Par ailleurs, le vitrage d'un panneau 2 est parfois en verre de sécurité du type trempé précontraint thermiquement ou équivalent, et, cette portion 7 biseautée de la face externe 8 de la vitre 5 étant fragilisée, la pièce 6 est apte à réaliser une ébréchure à cet endroit de la vitre 5 en cas de défaillance subite des moyens 4 d'association de la vitre 5 au châssis 3. De la sorte, la vitre 5 se brise en une multitude de petits morceaux lorsque la pièce 6 réalise une ébréchure sur la portion 7 de sa face externe 8.According to the invention, the external branch 13 is inclined towards the outside 22 in order to be able to cooperate with a portion 7 of the external face 8 of the window 5 which is bevelled with the same inclination. Furthermore, the glazing of a panel 2 is sometimes made of safety glass of the thermally pre-stressed tempered type or equivalent, and, this bevelled portion 7 of the external face 8 of the window 5 being weakened, the part 6 is capable of producing a chipping at this point of the glass 5 in the event of a sudden failure of the means 4 for associating the glass 5 with the frame 3. In this way, the glass 5 breaks into a multitude of small pieces when the part 6 produces a chipping on the portion 7 of its external face 8.

Cependant, la pièce 6 ne réalise cette ébréchure, et ne remplit donc sa fonction de destruction, qu'à partir d'un certain déplacement transversal (perpendiculai­rement au plan P du panneau 2) déterminé de ce panneau 2. Ainsi, on évite la destruction intempestive du vitrage en cas de déplacement brusque du panneau 2 sans détérioration effective des moyens 4 d'association du panneau 2 au châssis 3, par exemple en cas de déplacement dû à l'action du vent. Par ailleurs, même dans le cas où la pièce 6 n'a la fonction que de maintenir en place le vitrage (verre recuit, défaillance légère ou progressive des moyens 4 de fixation du panneau à la structure...), cette pièce 6 ne rentre en fonction qu'à partir d'un déplacement transversal minimum déterminé perpendiculairement au plan P. De la sorte, la pièce 6 ne travaille pas et n'affecte pas la durée de vie du produit en régime normal. Pour ce faire, la branche intermédiaire 14 comporte au moins un taraudage 25 d'axe 26 au moins sensiblement perpendiculaire au chant 12 correspondant de la vitre 5, taraudage 25 dans lequel peut être inséré un ergot fileté 15 destiné à coopérer avec une lumière 16 correspondante du châssis 3 pour retenir la pièce 6, notamment selon les directions perpendiculaires au plan P de la vitre 5. La lumière 16 a des dimensions plus importantes que l'ergot 15 de telle sorte que la coopération entre l'ergot 15 et la lumière 16 se fait avec un certain jeu 33, notamment dans toutes les directions afin d'éviter la mise en action intempestive de la fonction de maintien ou de destruction de la pièce 6, ou les contraintes trop importantes en cas de léger déplacement de la vitre 5 non accompagné d'une détérioration ou d'une défaillance des moyens 4 d'association de la vitre 5 au châssis 3. Ainsi, comme cela apparaît de la figure 2, la pièce 6 ne rentre en fonction qu'à partir d'un certain déplacement perpendiculairement au plan P de la vitre 5, déplacement qui est dimensionné pour correspondre nécessairement à une détérioration des moyens 4 d'association de cette vitre 5 au châssis 3. De la sorte, les légers déplacements naturels de la vitre 5 autorisés par l'élasticité des moyens 4 d'association de cette vitre 5 au châssis 3, ne sont pas contrariés par le dispositif de sécurité selon l'invention. Le jeu 23 prévu entre la patte 11 et le châssis 3 est supérieur ou égal au jeu 33 prévu entre l'ergot fileté 15 et la paroi interne de la lumière 16. On prévoit par exemple deux lumières 16, deux ergots filetés 15 et deux taraudages 25 par pièce 6, bien que seuls une lumière 16 et un ergot 15 aient été représentés sur les figures.However, the part 6 only achieves this chipping, and therefore fulfills its destruction function, only from a certain transverse displacement (perpendicular to the plane P of the panel 2) determined from this panel 2. Thus, destruction is avoided untimely glazing in the event of sudden movement of the panel 2 without effective deterioration of the means 4 for associating the panel 2 with the frame 3, for example in the event of displacement due to the action of the wind. Furthermore, even in the case where the part 6 has the function only of holding the glazing in place (annealed glass, slight or progressive failure of the means 4 for fixing the panel to the structure, etc.), this part 6 does not comes into operation only from a minimum transverse displacement determined perpendicular to the plane P. In this way, the part 6 does not work and does not affect the life of the product under normal conditions. To do this, the intermediate branch 14 comprises at least one thread 25 with axis 26 at least substantially perpendicular to the corresponding edge 12 of the window 5, thread 25 in which can be inserted a threaded lug 15 intended to cooperate with a corresponding light 16 of the frame 3 for retaining the part 6, in particular in the directions perpendicular to the plane P of the window 5. The light 16 has larger dimensions than the lug 15 so that the cooperation between the lug 15 and the light 16 is done with a certain clearance 33, in particular in all directions in order to avoid inadvertent activation of the function of maintaining or destroying the part 6, or the stresses which are too great in the event of slight movement of the window 5 no accompanied by deterioration or failure of the means 4 for associating the window 5 with the frame 3. Thus, as appears from the Figure 2, the part 6 does not come into operation until a certain movement perpendicular to the plane P of the window 5, movement which is dimensioned to necessarily correspond to a deterioration of the means 4 of association of this window 5 to the frame 3. In this way, the slight natural movements of the window 5 authorized by the elasticity of the means 4 for associating this window 5 with the frame 3, are not thwarted by the safety device according to the invention. The clearance 23 provided between the tab 11 and the chassis 3 is greater than or equal to the clearance 33 provided between the threaded lug 15 and the internal wall of the slot 16. For example, two slots 16, two threaded studs 15 and two threads are provided. 25 per part 6, although only a light 16 and a lug 15 have been shown in the figures.

L'invention concerne également un panneau de façade vitré à une seule vitre caractérisé en ce qu'il comporte un dispositif de sécurité selon l'invention, constitué d'au moins une pièce 6 qui lui est associée par collage ou équivalent sur une portion périphérique 10 de la face interne 9 de la vitre 5. Un panneau selon l'invention comporte au moins deux pièces 6 associées symétriquement à deux chants opposés 12 de la vitre 5 au voisinage de deux coins 24 de cette vitre 5, pour assurer le maintien en place de ce panneau 2. De préférence, le panneau 2 selon l'invention comporte quatre pièces 6 au voisinage de chacun des coins 24 de la vitre 5, et les quatres pièces 6 coopérent toutes avec des chants 12 de la vitre 5 qui s'étendent dans la même direction, c'est-à-dire verticalement ou horizontalement. Les différentes portions 7 de la face externe 8 de la vitre 5 destinées à coopérer avec les branches externes 13 des pièces 6 sont de préférence toutes fragilisées, c'est-à-dire en forme de biseau. On peut prévoir à cet effet soit de biseauter l'intégralité de la périphérie externe de la vitre 5, soit uniquement localement les portions 7 destinées à venir en contact avec une pièce 6. En variante, il est également possible de ne pas biseauter du tout la périphérie de la vitre 5, et de prévoir que la branche externe 13 des pièces 6 vienne à recouvrement de la portion 7 plane périphérique externe de la vitre 5. Une telle variante a l'inconvénient de laisser la branche externe 13 de la pièce 6 visible de l'extérieur. On peut donc également, selon une autre variante, prévoir de ménager une gorge le long d'une portion du chant 12, gorge dans laquelle la branche externe 13 d'une pièce 6 peut être insérée. Une pièce 6 selon l'invention peut aussi comporter des ergots, saillies ou équivalents, de coopération avec des rainures, gorges ou équivalents du fond de joint 18 ou du joint 19.The invention also relates to a glazed facade panel with a single pane characterized in that it comprises a safety device according to the invention, consisting of at least one part 6 which is associated with it by bonding or equivalent on a peripheral portion 10 of the internal face 9 of the window 5. A panel according to the invention comprises at least two parts 6 symmetrically associated with two opposite edges 12 of the window 5 in the vicinity of two corners 24 of this window 5, to ensure the maintenance in place of this panel 2. Preferably, the panel 2 according to the invention comprises four parts 6 in the vicinity of each of the corners 24 of the window 5, and the four parts 6 all cooperate with edges 12 of the window 5 which are extend in the same direction, i.e. vertically or horizontally. The different portions 7 of the external face 8 of the window 5 intended to cooperate with the external branches 13 of the parts 6 are preferably all weakened, that is to say in the form of a bevel. One can provide for this purpose either to bevel the entire outer periphery of the window 5, or only locally the portions 7 intended to come into contact with a part 6. As a variant, it is also possible not to bevel at all the periphery of the glass 5, and to provide that the external branch 13 of the parts 6 comes to overlap the planar outer peripheral portion 7 of the glass 5. Such a variant has the disadvantage of leaving the external branch 13 of the part 6 visible from the outside. It is therefore also possible, according to another variant, to provide a groove along a portion of the edge 12, groove in which the outer branch 13 of a part 6 can be inserted. A part 6 according to the invention may also include lugs, protrusions or the like, for cooperation with grooves, grooves or the like of the seal bottom 18 or seal 19.

Dans le mode de réalisation préférentiel représenté, où la branche externe 13 de la pièce 6 est inclinée vers l'extérieur et où la portion 7 est biseautée, on peut remarquer que le joint 27 qui est de toute façon prévu entre le bord périphérique de la vitre 5 et le châssis 3, vient recouvrir la branche externe 13 de la pièce 6, et ainsi cacher le dispositif de sécurité.In the preferred embodiment shown, where the outer branch 13 of the part 6 is inclined outward and where the portion 7 is bevelled, it can be noted that the seal 27 which is in any case provided between the peripheral edge of the window 5 and the frame 3, covers the outer branch 13 of the part 6, and thus hide the safety device.

Selon l'invention, chaque pièce 6 est associée à la vitre 5 par interposition entre la face interne 9 de la vitre 5 et la patte 11, de l'extérieur 22 vers l'inté­rieur 21, d'une part d'un fond de joint 18 adhésif, notamment en mousse polyuré­thane, et d'autre part d'un joint d'association 19 également adhésif, notamment en silicone, qui est superposé au fond de joint 18 vers l'intérieur et vers la partie centrale de la vitre 5.According to the invention, each part 6 is associated with the window 5 by interposition between the internal face 9 of the window 5 and the tab 11, from the outside 22 towards the inside 21, on the one hand from a bottom of adhesive seal 18, in particular made of polyurethane foam, and on the other hand an association seal 19 also adhesive, in particular silicone, which is superimposed on the seal bottom 18 towards the inside and towards the central part of the glass 5 .

Un procédé d'association d'un dispositif de sécurité selon l'invention à un panneau vitré 2 constitué d'une vitre unique 5 est caractérisé en ce que l'on place un fond de joint 18, notamment en mousse polyuréthane, localement à l'extrême périphérie 28 de la face interne 9 de la vitre 5, à l'emplacement où une pièce 6 doit être fixée, on emboîte ensuite cette pièce 6 en coinçant le fond de joint 18 entre la patte 11 et la vitre 5, puis on dépose un joint adhésif 19, notamment en silicone, à recouvrement vers l'intérieur du fond de joint 18, entre la partie extrême 29 libre de la face 11 et la vitre 5. On emboîte la pièce 6 sur le fond de joint 18. Lorsque la pièce 6 est emboîtée sur le fond de joint 18, elle est maintenue en place par l'élasticité de ce fond de joint 18 qui est coincé entre la patte 11 et la face interne 9 de la vitre 5. Ainsi, on peut ensuite aisément déposer le joint 19 en silicone qui, en polymérisant, adhèrera parfaitement et à la face interne 9 de la vitre 5, et à la partie extrême libre 29 de la patte 11 de la pièce 6. Les pièces 6 sont montées sur le panneau 2 en atelier.A method of associating a safety device according to the invention with a glazed panel 2 consisting of a single pane 5 is characterized in that a joint bottom 18, in particular made of polyurethane foam, is placed locally at the 'extreme periphery 28 of the internal face 9 of the window 5, at the location where a part 6 must be fixed, this part 6 is then fitted together by wedging the joint bottom 18 between the tab 11 and the window 5, then deposits an adhesive seal 19, in particular made of silicone, overlapping towards the inside of the seal bottom 18, between the free end portion 29 of the face 11 and the window 5. The part 6 is fitted onto the seal bottom 18. When the part 6 is fitted onto the joint bottom 18, it is held in place by the elasticity of this joint bottom 18 which is wedged between the tab 11 and the internal face 9 of the window 5. Thus, it is then possible easily deposit the silicone gasket 19 which, when polymerized, will adhere perfectly and the inner face 9 of the pane 5, and the free end portion 29 of the leg 11 of the part 6. The parts 6 are mounted on the panel 2 in the workshop.

Un panneau selon l'invention arrive donc sur le chantier prêt à être monté avec au moins deux, et de préférence quatre pièces 6 de sécurité placées au voisinage de chacun de ses coins 24. Pour fixer le panneau 2 la structure 1 du bâtiment, on peut par exemple disposer les joints d'association et/ou d'étan­chéité à la périphérie interne du panneau 2, puis procéder au collage de ce panneau 2 sur le châssis 3 de la structure rigide 1, puis, lorsque le collage est définitif et rigide, on visse les différents ergots 15 filetés dans les taraudages 25 des pièces 6 profilées à travers les lumières 16 prévues dans le châssis 3. On peut ensuite placer les joints extérieurs 27 en recouvrant les pièces 6. Les moyens 4 d'association de la vitre 5 au châssis 3 sont par exemple constitués d'un joint d'étanchéité 30 et d'un joint d'association 31. Au niveau des diffé­rentes pièces 6, on peut soit décaler ces joints vers la partie centrale de la vitre 5 comme indiqué à la figure 2 localement par rapport à leur position normale périphérique, soit les décaler de la même façon mais sur toute la péri­phérie interne du vitrage 5, soit encore interrompre ces joints 30, 31 au niveau de chaque pièce 6.A panel according to the invention therefore arrives on the site ready to be mounted with at least two, and preferably four safety pieces 6 placed in the vicinity of each of its corners 24. To fix the panel 2 the structure 1 of the building, can for example arrange the association and / or sealing joints at the internal periphery of the panel 2, then proceed to the bonding of this panel 2 on the chassis 3 of the rigid structure 1, then, when the bonding is final and rigid , we screw the different lugs 15 threaded in the threads 25 of the parts 6 profiled through the slots 16 provided in the frame 3. The outer seals 27 can then be placed by covering the parts 6. The means 4 for associating the window 5 with the frame 3 are for example made up of a seal 30 and an association seal 31. At the level of the various parts 6, these seals can either be shifted towards the central part of the window 5 as indicated in FIG. 2 locally relative to their normal peripheral position , either shift them in the same way but over the entire inner periphery of the glazing 5, or else interrupt these seals 30, 31 at the level of each part 6.

Parmi les nombreux avantages qui apparaissent clairement de la description précédente, on peut noter que les pièces 6 sont extrêmement simples à fabriquer, extrêmement simples à monter, et conservent une efficacité parfaite avec un fonctionnement équivalent à celui des pièces déjà connues pour les vitrages multiples. Une pièce 6 selon l'invention a par exemple une patte 11 dont la longueur parallèlement au plan P de la vitre 5 est comprise entre 5 et 15 mm, notamment de l'ordre de 10 mm, et qui détermine une épaisseur totale perpendi­culairement au plan P du vitrage à partir de la face interne 9, y compris les joints 19 et fonds de joints 18, comprise entre 3 et 10 mm, notamment de l'ordre de 5 mm. L'inclinaison de la branche externe 13, et de la partie biseautée 7 de la face externe 8 par rapport au plan P varie en fonction de divers facteurs, et notamment de l'épaisseur de la vitre 5. Cette inclinaison est par exemple de l'ordre de 45° pour une vitre 5 de l'ordre de 8 mm d'épaisseur. Cependant, les inventeurs ont mis en évidence que l'invention est applicable également avec des vitres dont l'épaisseur est de 6 mm, valeur minimale autorisée par les réglementations françaises. En effet, dans ce cas, il suffit de prévoir une inclinaison de l'ordre de 30° par rapport au plan P pour la branche externe 13 et la partie biseautée 7. Les essais ont montré en effet qu'une telle incli­naison permet d'insérer correctement la pièce 6, de poser le joint extérieur 27, et d'obtenir de bonnes performances du dispositif de sécurité selon l'invention.Among the many advantages which appear clearly from the preceding description, it can be noted that the parts 6 are extremely simple to manufacture, extremely simple to assemble, and maintain perfect efficiency with an operation equivalent to that of the parts already known for multiple glazing. A piece 6 according to the invention has for example a tab 11 whose length parallel to the plane P of the window 5 is between 5 and 15 mm, in particular of the order of 10 mm, and which determines a total thickness perpendicular to the plane P of the glazing from the internal face 9, including the seals 19 and joint surfaces 18, between 3 and 10 mm, in particular of the order of 5 mm. The inclination of the external branch 13, and of the bevelled part 7 of the external face 8 relative to the plane P varies as a function of various factors, and in particular of the thickness of the window 5. This inclination is for example of the '' around 45 ° for a window 5 of the order of 8 mm thick. However, the inventors have demonstrated that the invention is also applicable with panes whose thickness is 6 mm, the minimum value authorized by French regulations. Indeed, in this case, it suffices to provide an inclination of the order of 30 ° relative to the plane P for the external branch 13 and the bevelled part 7. The tests have shown that such an inclination makes it possible to correctly insert the part 6, install the outer seal 27, and obtain good performance of the safety device according to the invention.
