Description

L'invention se rapporte à un panneau de verre non trempé, de préférence feuilleté et équipé d'un accessoire fixé au panneau au travers d'un trou de celui-ci. L'invention concerne plus particulièrement un perfectionnement permettant d'éviter la rupture d'un tel panneau, notamment au moment du montage de l'accessoire par "filage" du verre à partir des bords du trou.The invention relates to a non-tempered glass panel, preferably laminated and equipped with an accessory attached to the panel through a hole thereof. The invention relates more particularly to an improvement to prevent the breakage of such a panel, especially when mounting the accessory by "spinning" the glass from the edges of the hole.

On connaît notamment le document US 6 463 628 qui divulgue une poignée de porte pour un panneau de verre.The document is particularly known US 6,463,628 which discloses a door handle for a glass panel.

Dans le domaine de la verrerie, on distingue essentiellement deux catégories : le verre trempé et le verre non trempé, de préférence un verre non trempé feuilleté où plusieurs couches de verres sont accolées avec interposition d'un film polymère entre deux couches adjacentes.In the field of glassware, there are essentially two categories: the toughened glass and untempered glass, preferably a laminated non-toughened glass where several layers of glass are contiguous with the interposition of a polymer film between two adjacent layers.

Le verre trempé est très résistant et on peut, sans risque, équiper un panneau de verre trempé d'un accessoire, généralement métallique monté serré de part et d'autre du panneau et traversant un trou de celui-ci. Cependant, le verre trempé n'est pas façonnable par un miroitier non équipé d'un four de trempe. Par exemple, un simple trou doit être pratiqué avant la trempe. Ces opérations rendent le verre trempé plus cher que le verre non trempé (même feuilleté) : compte tenu des équipements nécessaires pour la trempe, il est parfois nécessaire d'envoyer le panneau en usine ou au moins dans une unité éloignée équipée d'un four adapté, ce qui allonge les délais de livraison. D'une façon générale, le verre trempé est donc moins disponible, pour l'utilisateur, que le verre non trempé.Tempered glass is very resistant and it is safe to equip a tempered glass panel with an accessory, generally metal mounted tight on both sides of the panel and passing through a hole thereof. However, tempered glass can not be shaped by a mirror without a quenching furnace. For example, a simple hole must be made before quenching. These operations make tempered glass more expensive than untempered glass (even laminated): given the equipment required for quenching, it is sometimes necessary to send the panel at the factory or at least in a remote unit equipped with an oven adapted, which lengthens the delivery times. In general, therefore, tempered glass is less available to the user than non-tempered glass.

Au contraire, le verre non trempé ou feuilleté peut facilement être façonné.On the contrary, untempered or laminated glass can easily be shaped.

N'importe quel miroitier même sommairement équipé peut y pratiquer des trous pour le montage d'accessoires, tels que des plots de fixation, notamment pour des charnières ou encore pour l'installation de poignées.Any mirror even summarily equipped can practice holes for mounting accessories, such as mounting studs, especially for hinges or for the installation of handles.

En revanche, le montage d'un tel accessoire, au travers du trou se traduit parfois par une rupture du verre selon des fentes rayonnantes partant des bords du trou, si on maîtrise mal le serrage. Ce phénomène est appelé couramment "filage".However, the mounting of such an accessory through the hole sometimes results in a rupture of the glass according to radiating slots leaving the edges of the hole, if we do not control tightness. This phenomenon is commonly called "spinning".

On a envisagé de concevoir des accessoires présentant une grande surface de contact autour des trous pour répartir les efforts résultants du serrage, sur une plus grande surface.It has been envisaged to design accessories having a large contact area around the holes to distribute the resulting tightening forces over a larger area.

Or, pour des raisons de coût et d'ordre esthétique, il est souhaitable que ces accessoires rapportés soient le moins volumineux possible. L'invention vise à atteindre cet objectif.However, for reasons of cost and aesthetic order, it is desirable that these reported accessories are the least bulky possible. The invention aims to achieve this objective.

Elle est le fruit de l'analyse selon laquelle le verre non trempé ou non trempé feuilleté a une mauvaise résistance à la flexion et qu'on peut attribuer le "filage" rayonnant du verre à partir des bords du trou à des efforts de flexion non contrôlés au serrage de l'accessoire, entrainant la rupture à partir des microfissures existant le long du périmètre du trou. Par ailleurs, ce verre a une excellente résistance à la compression (30 fois plus élevées que la résistance à la flexion).It is the result of the analysis that non-tempered or non-tempered laminated glass has poor flexural strength and that the radiating "spinning" of the glass can be attributed from the edges of the hole to non-flexural forces. controlled by tightening the accessory, causing breakage from existing microcracks along the perimeter of the hole. In addition, this glass has excellent compressive strength (30 times higher than flexural strength).

L'idée de base de l'invention consiste donc à agencer l'accessoire pour que son montage serré n'engendre que des efforts de compression à une certaine distance du trou, préservant les bords de ce trou de tout effort de traction où les microfissures résultants du perçage pourraient constituer des amorces de rupture responsables du phénomène de filage.The basic idea of the invention therefore consists in arranging the accessory so that its tight fitting engenders only compressive forces at a certain distance from the hole, preserving the edges of this hole of any tensile stress where the microcracks resulting from the drilling could constitute rupture primers responsible for the spinning phenomenon.

A cet effet, l'invention concerne en premier lieu un panneau de verre non trempé équipé d'un accessoire engagé au travers d'un trou de ce panneau et enserrant les deux faces opposées de celui-ci, caractérisé en ce que ledit accessoire comporte deux platines de montage assemblées entre elles avec serrage pour mettre sous contrainte de compression une zone dudit panneau entourant le trou et en ce que lesdites platines de montage sont conformées pour définir une zone de contact à contour fermé tout autour dudit trou dont le bord intérieur se trouve en tout point à une distance sensiblement au moins égale à une valeur minimum prédéterminée du bord dudit trou, définissant une zone de serrage éloignée du trou.For this purpose, the invention relates firstly to an unhardened glass panel equipped with an accessory engaged through a hole of this panel and enclosing the two opposite faces thereof, characterized in that said accessory comprises two mounting plates clampingly joined together to compress a zone of said panel surrounding the hole and in that said mounting plates are shaped to define a closed contour contact area around said hole whose inner edge is at any point at a distance substantially at least equal to a predetermined minimum value of the edge of said hole, defining a clamping zone remote from the hole.

Ainsi, la mise en compression du verre en une zone globalement annulaire éloignée du trou, isole complètement celui-ci de toute contrainte, notamment de flexion. On peut envisager de serrer l'accessoire sans avoir à prendre de précautions excessives, même en déployant un effort de serrage important puisque celui-ci ne fait que créer une zone de compression dans l'épaisseur du verre à une distance suffisante du trou.Thus, compressing the glass into a generally annular zone remote from the hole, completely isolates it from any stress, particularly bending. One can consider tightening the accessory without having to take excessive precautions, even by deploying a large clamping force since it only creates a compression zone in the thickness of the glass at a sufficient distance from the hole.

Avantageusement, on a déterminé que lorsque, par exemple, le verre étant monolithique et non trempé, la valeur minimum prédéterminée peut être considérée comme égale à l'épaisseur dudit panneau.Advantageously, it has been determined that when, for example, the glass being monolithic and not hardened, the predetermined minimum value can be considered equal to the thickness of said panel.

Dans le cas d'une plaque de verre feuilleté, composée comme on le sait de plusieurs couches (au moins deux) de verre non trempé accolée via un film de matière plastique, on a déterminé que ladite valeur minimum peut être considérée comme égale à l'épaisseur de la couche extérieure la plus épaisse du panneau de verre feuilleté.In the case of a laminated glass plate, composed as is known of several layers (at least two) of non-tempered glass contiguous via a plastic film, it has been determined that said minimum value can be considered as equal to thickness of the thickest outer layer of the laminated glass panel.

Une autre caractéristique importante de l'invention concerne le dimensionnement de l'accessoire lui-même qui, comme on l'a indiqué ci-dessus, ne doit pas être plus grand que ce qu'impose sa fonction.Another important feature of the invention relates to the dimensioning of the accessory itself which, as stated above, should not be larger than that imposed by its function.

A cet effet, avantageusement, l'invention propose dans le cas d'un panneau de verre monolithique et non trempé, que la largeur de la zone de serrage de la platine de montage, à l'extérieur dudit contour fermé soit au moins sensiblement égale à l'épaisseur dudit panneau.For this purpose, advantageously, the invention proposes in the case of a monolithic and unhardened glass panel, that the width of the clamping zone of the mounting plate, outside said closed contour is at least substantially equal to to the thickness of said panel.

Dans le cas d'un verre non trempé feuilleté, on a déterminé que la largeur de la zone de serrage d'une platine de montage, à l'extérieur dudit contour fermé, est au moins sensiblement égale à l'épaisseur de la couche sur laquelle elle prend appui. Pour des raisons d'esthétique, il est clair que le plus souvent la largeur de cette zone de serrage sera la même de part et d'autre du panneau et que, par conséquent, on choisira cette largeur au moins sensiblement égale à l'épaisseur de la couche extérieure la plus épaisse.In the case of a non-laminated laminated glass, it has been determined that the width of the clamping zone of a mounting plate, outside said closed contour, is at least substantially equal to the thickness of the layer on which she supports. For reasons of aesthetics, it is clear that most often the width of this clamping zone will be the same on both sides of the panel and that, therefore, this width will be chosen at least substantially equal to the thickness the thickest outer layer.

Une caractéristique concrète d'une platine de montage définie ci-dessus est que, par exemple, sa partie centrale au voisinage d'un trou qui doit venir en regard du trou du panneau de verre comporte un lamage, par exemple de l'ordre du mm, s'étendant jusqu'audit contour fermé. De cette façon, on évite tout contact entre ladite platine de montage et le verre au voisinage du trou pratiqué dans le panneau de verre.A concrete characteristic of a mounting plate defined above is that, for example, its central portion in the vicinity of a hole which must come opposite the hole of the glass panel comprises a countersink, for example of the order of mm, extending to this closed contour. In this way, it avoids any contact between said mounting plate and the glass in the vicinity of the hole made in the glass panel.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés :

  • la figure 1 est une vue en coupe d'une porte en verre, munie de poignées, les poignées étant montées conformément au principe de l'invention ;
  • la figure 2 est une vue de détail à plus grande échelle de l'encadré II la figure 1 ; et
  • la figure 3 représente une platine de montage vue selon la coupe III de la figure 2.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the description which follows, given solely by way of example and with reference to the appended drawings:
  • the figure 1 is a sectional view of a glass door, provided with handles, the handles being mounted in accordance with the principle of the invention;
  • the figure 2 is a larger-scale detail view of Box II la figure 1 ; and
  • the figure 3 represents a mounting plate seen according to section III of the figure 2 .

En se référant aux dessins, on a représenté en coupe, une porte 11 en verre non trempé, de préférence feuilleté, munie de deux poignées 13, 14 situées de part et d'autre du panneau de verre 16 constituant la porte. Chaque poignée 13, 14 est constituée par un tube vertical s'étendant à distance dudit panneau de verre 16 en étant espacé de celui-ci par des entretoises tubulaires 19, 20. Le tube 14 formant l'une des poignées, par exemple la poignée intérieure, abrite une serrure à barillet 22 classique, associée à un mécanisme de verrouillage à crémone 24, présentant deux pênes susceptibles de coopérer avec le bâti de porte, respectivement un pêne haut 23 et un pêne bas 27. Le système de serrure ne fait pas partie de l'invention.Referring to the drawings, there is shown in section, a door 11 of untempered glass, preferably laminated, provided with two handles 13, 14 located on either side of the glass panel 16 constituting the door. Each handle 13, 14 is constituted by a vertical tube extending at a distance from said glass panel 16 being spaced from it by tubular spacers 19, 20. The tube 14 forming one of the handles, for example the handle inside, houses a conventional cylinder lock 22, associated with a locking mechanism 24, having two bolts capable of cooperating with the door frame, respectively a top bolt 23 and a bottom bolt 27. The lock system does not part of the invention.

La figure 2 illustre mieux le montage des deux entretoises 20a, 20b supportant les deux poignées 13, 14, en partie basse. Ces deux entretoises (et les poignées) peuvent être considérés comme faisant partie de "l'accessoire" défini ci-dessus.The figure 2 illustrates better the mounting of the two spacers 20a, 20b supporting the two handles 13, 14, in the lower part. These two spacers (and the handles) can be considered as part of the "accessory" defined above.

Les entretoises 20a, 20b tubulaires abritent une vis 21 traversant un trou 26 pratiqué dans le panneau de verre 16. La tête de vis 25 a un diamètre correspondant sensiblement au diamètre intérieur de l'entretoise 20a et son extrémité filetée vient se visser dans une portion taraudée intérieurement 29 de l'entretoise 20b. Une bague intérieure 31 fixée à l'extrémité de l'entretoise 20a forme un épaulement intérieur pour l'application de la tête de vis 25.The tubular spacers 20a, 20b house a screw 21 passing through a hole 26 formed in the glass panel 16. The screw head 25 has a diameter substantially corresponding to the inside diameter of the spacer 20a and its threaded end is screwed into a portion internally tapped 29 of the spacer 20b. An inner ring 31 attached to the end of the spacer 20a forms an inner shoulder for the application of the screw head 25.

Selon une caractéristique importante, l'accessoire (poignée et surtout entretoises) comporte aussi deux platines de montage 35, ici en forme de bague plate, par exemple en acier, de préférence en acier inoxydable. Chaque platine comporte un trou central 37 à l'intérieur duquel la vis est engagée à coulissement.According to an important characteristic, the accessory (handle and especially spacers) also comprises two mounting plates 35, here in the form of flat ring, for example steel, preferably stainless steel. Each plate has a central hole 37 inside which the screw is slidably engaged.

De plus, une cale annulaire 40 en matière plastique est intercalée entre chaque platine 35 et la surface du panneau de verre 16 autour du trou 26 pratiqué dans celui-ci. Le diamètre extérieur de la cale est sensiblement égal à celui de la platine et son diamètre intérieur correspond au diamètre de la vis.In addition, an annular wedge 40 of plastic material is interposed between each plate 35 and the surface of the panel 16 around the hole 26 practiced therein. The outer diameter of the wedge is substantially equal to that of the plate and its inside diameter corresponds to the diameter of the screw.

Dans l'exemple, le diamètre du trou 26 pratiqué dans la plaque de verre est légèrement supérieur au diamètre de la vis. Si nécessaire, pour faciliter le montage et surtout le centrage, on peut insérer un manchon, par exemple en matière plastique entre la paroi intérieure cylindrique du trou 26 pratiqué dans le panneau de verre et la surface extérieure de la vis 21. Chaque platine de montage comporte un lamage 44 de faible profondeur, à contour fermé 46 circulaire, centré, de façon à définir dans le verre et à l'extérieur dudit contour fermé, une zone de serrage annulaire 48, éloignée du bord du trou 26. Ainsi, les deux platines de montage 35 assemblées entre elles avec serrage, grâce à la vis 21, de part et d'autre du panneau de verre 16 permettent de mettre sous contrainte de compression une zone annulaire dans ledit panneau, entourant le trou en préservant les bords de ce dernier de tout effort de traction. Les platines de montage sont donc conformées pour définir, chacune, une zone de contact plate 51, à contour fermé, ici annulaire, tout autour du trou et le bord intérieur de cette zone de contact (ledit contour fermé 46) se trouve en tout point à une distance sensiblement au moins égale à une valeur minimum, prédéterminée, du bord du trou. Comme mentionné précédemment, cette valeur minimum prédéterminée est égale à l'épaisseur dudit panneau. Cela signifie que le diamètre D du bord extérieur du lamage est au moins égal au diamètre du trou 26 augmenté de deux fois l'épaisseur du panneau.In the example, the diameter of the hole 26 formed in the glass plate is slightly greater than the diameter of the screw. If necessary, to facilitate the assembly and especially the centering, can be inserted a sleeve, for example plastic between the cylindrical inner wall of the hole 26 formed in the glass panel and the outer surface of the screw 21. Each mounting plate comprises a countersink 44 of small depth, circular closed contour 46, centered, so as to define in the glass and outside said closed contour, an annular clamping zone 48, remote from the edge of the hole 26. Thus, both mounting plates 35 assembled together with clamping, by means of the screw 21, on either side of the glass panel 16 allow to put under compressive stress an annular zone in said panel, surrounding the hole while preserving the edges of this last of all pulling effort. The mounting plates are thus shaped to define, each, a flat contact area 51, closed contour, here annular, all around the hole and the inner edge of this contact area (said closed contour 46) is at all points at a distance substantially at least equal to a predetermined minimum value of the edge of the hole. As mentioned above, this predetermined minimum value is equal to the thickness of said panel. This means that the diameter D of the outer edge of the counterbore is at least equal to the diameter of the hole 26 increased by twice the thickness of the panel.

Si le verre non trempé est du type feuilleté, comme par exemple représenté sur la figure 2 où on distingue que le panneau est constitué de trois couches de verre C1, C2, C3 accolées, alors ladite valeur minimum est égale à l'épaisseur de la couche extérieure la plus épaisse, c'est-à-dire ici la couche C1. Par conséquent, le diamètre D est au moins égal (généralement supérieur) au diamètre du trou 26 augmenté de deux fois l'épaisseur de la couche C1.If the unhardened glass is of the laminated type, as for example represented on the figure 2 where it is distinguished that the panel consists of three layers of glass C1, C2, C3 contiguous, then said minimum value is equal to the thickness of the thickest outer layer, that is to say here the layer C1. Therefore, the diameter D is at least equal (generally greater) than the diameter of the hole 26 increased by twice the thickness of the layer C1.

De plus, on a déterminé que la largeur d de la zone de serrage d'une telle platine de montage 35, à l'extérieur du contour fermé de diamètre D, est au moins sensiblement égale à l'épaisseur e du panneau, ceci dans le cas où ledit panneau est monolithique.In addition, it has been determined that the width d of the clamping zone of such a mounting plate 35, outside the closed contour of diameter D, is at least substantially equal to the thickness e of the panel, this in the case where said panel is monolithic.

Dans le cas d'un panneau en verre feuilleté, la largeur d de la zone de contact d'une telle platine de montage 35 à l'extérieur dudit contour fermé de diamètre D est au moins sensiblement égale à l'épaisseur de la couche sur laquelle elle prend appui. Dans la pratique, où les platines sont identiques, cela revient à choisir la largeur de la zone de serrage de la platine de montage au moins sensiblement égale à l'épaisseur de la couche extérieure C1 la plus épaisse.In the case of a laminated glass panel, the width d of the contact area of such a mounting plate 35 outside said closed contour of diameter D is at least substantially equal to the thickness of the layer on which she supports. In practice, where the plates are identical, this amounts to choosing the width of the clamping zone of the mounting plate at least substantially equal to the thickness of the outermost layer C1 thickest.

Bien entendu, les principes de l'invention énoncés ci-dessus sont applicables à tout autre type d'accessoire susceptible d'être monté sur un panneau de verre non trempé. On a représenté l'accessoire sous forme d'une poignée et plus particulièrement les platines de montage d'une telle poignée mais, par exemple, l'accessoire en question peut aussi former un plot de montage pour tout autre élément, notamment une charnière.Of course, the principles of the invention set out above are applicable to any other type of accessory that can be mounted on a non-tempered glass panel. The accessory is shown in the form of a handle and more particularly the mounting plates of such a handle but, for example, the accessory in question may also form a mounting stud for any other element, including a hinge.
