Description

La présente invention concerne les éléments qui permettent de réaliser des charnières comme celles qui trouvent une infinité d'applications dont les plus courantes sont. par exemple, de constituer des moyens de rotation de portes, volets, etc, par rapport à des embases ou châssis.The present invention relates to elements which make it possible to produce hinges such as those which find an infinity of applications, the most common of which are. for example, to constitute means for rotating doors, shutters, etc., relative to bases or frames.

Une charnière, comme celles qui sont le plus couramment utilisées, est essentiellement constituée par une paumelle et un gond. ces deux pièces coopérant l'une avec l'autre au moyen d'un arbre solidaire de l'une et d'un palier réalisé dans l'autre, l'arbre pivotant dans le palier pour obtenir la rotation de la paumelle par rapport au gond. Ces deux pièces sont aussi désignées par les techniciens par "corps dormant" quand il est fixé sur le châssis et "corps ouvrant" quand il est fixé sur l'objet pivotant par rapport au châssis.A hinge, like the most commonly used, is essentially a hinge and a hinge. these two parts cooperating with each other by means of a shaft integral with one and a bearing produced in the other, the shaft pivoting in the bearing to obtain the rotation of the hinge relative to the hinge. These two parts are also designated by technicians by "sleeping body" when it is fixed on the chassis and "opening body" when it is fixed on the pivoting object relative to the chassis.

Ces deux pièces sont de plus réalisées pour que, à chaque paumelle, corresponde un gond et réciproquement. Dans ces conditions, les fabricants sont obligés de prévoir deux gammes de fabrication. une pour chaque pièce, d'autant plus larges que de nombreux domaines techniques utilisent des charnières de tous types et de toutes dimensions. Comme, de plus, certains des outils nécessaires à la réalisation de chaque pièce sont spécifiques à chaque gamme de fabrication, il s'en suit que le prix de revient de chaque pièce est relativement élevé, malgré les quantités importantes fabriquées.These two pieces are also made so that, with each hinge, there is a hinge and vice versa. Under these conditions, manufacturers are obliged to provide two production ranges. one for each part, all the more wide as many technical fields use hinges of all types and all dimensions. As, moreover, some of the tools necessary for the production of each part are specific to each manufacturing range, it follows that the cost price of each part is relatively high, despite the large quantities manufactured.

La présente invention a ainsi pour but de réaliser des éléments pour charnières, qui permettent de réduire le coût de revient d'au moins une grande partie des charnières que l'on trouve dans le commerce, notamment celles qui sont utilisées dans la construction des bâtiments.The object of the present invention is thus to produce elements for hinges, which make it possible to reduce the cost price of at least a large part of the hinges which are found in commerce, in particular those which are used in the construction of buildings. .

Plus précisément, la présente invention a pour objet un élément permettant de réaliser des charnières, caractérisé par le fait qu'il est constitué d'un corps unitaire inscrit dans une surface cylindrique, ledit corps comportant deux parties d'extrémités. une percée traversante réalisée dans chaque partie d'extrémité suivant la génératrice de ladite surface cylindrique, deux parties de parois respectivement solidaires des deux dites parties d'extrémités, et une portion de paroi solidaire des deux dites parties de parois, ladite portion de paroi présentant au moins un point de faiblesse dans sa liaison avec les deux dites parties de parois permettant de séparer celles-ci sous un effort de rupture relativement faible.More specifically, the subject of the present invention is an element making it possible to produce hinges, characterized in that it consists of a unitary body inscribed in a cylindrical surface, said body comprising two end parts. a through hole made in each end part along the generatrix of said cylindrical surface, two wall parts respectively secured to the two said end parts, and a wall portion secured to the two said wall parts, said wall portion having at least one point of weakness in its connection with the two said wall parts making it possible to separate the latter under a relatively low breaking force.

D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description suivante donnée en regard des dessins annexés à titre illustratif mais nullement limitatif dans lesquels:

  • Les Figures 1 et 2 représentent deux vues, respectivement de dessus et en perspective, d'un mode de réalisation d'un élément selon l'invention, et
  • Les Figures 3 et 4 représentent différentes étapes de la réalisation d'une charnière obtenue avec un élément selon l'invention tel que représenté sur les Figures 1 et 2.
Other characteristics and advantages of the present invention will appear during the following description given with reference to the drawings annexed by way of illustration but in no way limitative in which:
  • Figures 1 and 2 show two views, respectively from above and in perspective, of an embodiment of an element according to the invention, and
  • Figures 3 and 4 show different stages in the production of a hinge obtained with an element according to the invention as shown in Figures 1 and 2.

Les deux Figures 1 et 2 représentent un mode de réalisation d'un élément 1 permettant de réaliser des charnières qui trouvent une application, notamment dans le domaine du bâtiment, pour le montage des fermetures, c'est-à-dire des portes, fenêtres, volets, etc.The two Figures 1 and 2 represent an embodiment of an element 1 making it possible to produce hinges which find an application, in particular in the building sector, for mounting closures, that is to say doors, windows , shutters, etc.

L'élément 1 est essentiellement constitué d'un corps unitaire 2 inscrit dans une surface cylindrique 13 dont la directrice 3 a une forme telle que celle représentée sur la Figure 1 qui en outre représente l'élément 1 en vue de dessus.The element 1 essentially consists of a unitary body 2 inscribed in a cylindrical surface 13 whose director 3 has a shape such as that shown in Figure 1 which further represents the element 1 in top view.

Ce corps unitaire 2 comporte deux parties d'extrémités 4, 5 avantageusement de forme renflées, une percée traversante 6, 7 réalisée dans chaque partie d'extrémité 4, 5 suivant la génératrice de la surface cylindrique, deux parties de parois 8, 9 solidaires respectivement des deux parties d'extrémités 4, 5 et une portion de paroi 10 solidaire des deux parties de parois 8, 9, cette portion de paroi 10 étant d'une longueur, suivant la génératrice de la surface cylindrique 13 définie ci-dessus, très inférieure à la longueur des parties de parois 8, 9 suivant cette génératrice.This unitary body 2 comprises two end parts 4, 5 advantageously of a swollen shape, a through-hole 6, 7 produced in each end part 4, 5 along the generatrix of the cylindrical surface, two parts of walls 8, 9 integral respectively of the two end parts 4, 5 and a wall portion 10 integral with the two wall parts 8, 9, this wall portion 10 being of a length, along the generatrix of the cylindrical surface 13 defined above, much less than the length of the wall portions 8, 9 along this generatrix.

Dans un mode de réalisation avantageux comme celui qui est illustré sur les Figures 1 à 4, les longueurs. suivant la génératrice de la surface cylindrique, des deux parties de parois 8, 9 et des deux parties d'extrémités 4, 5 sont égales et leurs bords situés d'un même côté 14-17 et 18-21 sont dans un même plan.In an advantageous embodiment such as that illustrated in FIGS. 1 to 4, the lengths. along the generatrix of the cylindrical surface, the two wall parts 8, 9 and the two end parts 4, 5 are equal and their edges located on the same side 14-17 and 18-21 are in the same plane.

Avec cet élément 1, il est possible de réaliser très avantageusement une charnière, par exemple en suivant les étapes décrites en regard des Figures 3 et 4.With this element 1, it is possible very advantageously to produce a hinge, for example by following the steps described with reference to Figures 3 and 4.

Pour ce faire, la portion de paroi 10 est éliminée de façon à obtenir la séparation des deux parties de parois 8, 9, par exemple en cassant cette portion de paroi 10. Dans ce but et dans un mode de réalisation préférentiel, cette portion de paroi présente au moins un point de faiblesse dans sa liaison avec les deux parties de parois 8, 9, par exemple une diminution d'épaisseur longitudinale qui va constituer un ensemble de points de faiblesse sur lesquels il suffira de produire un effort de torsion, par exemple manuel. suffisamment faible pour obtenir la rupture de la portion de paroi 10.To do this, the wall portion 10 is eliminated so as to obtain the separation of the two wall portions 8, 9, for example by breaking this wall portion 10. For this purpose and in a preferred embodiment, this portion of wall has at least one point of weakness in its connection with the two parts of walls 8, 9, for example a reduction in longitudinal thickness which will constitute a set of points of weakness on which it will suffice to produce a torsional force, by manual example. sufficiently weak to obtain the rupture of the wall portion 10.

Ensuite, au moyen de tout outil adapté, on élimine les morceaux de portion de paroi 10 qui pourraient être restés solidaires des deux parties de parois 8, 9, pour obtenir deux pièces complètement séparées sans aspérités disgracieuses. comme celles qui sont illustrées sur la figure 3.Then, by means of any suitable tool, the pieces of wall portion 10 which could have remained integral with the two wall parts 8, 9 are eliminated, in order to obtain two completely separate pieces without unsightly roughness. like those illustrated in figure 3.

Une chemise 25, 26 est enfichée dans chaque percée traversante 6, 7, l'une 26 de ces chemises comportant un arbre de rotation émergeant 27 et l'autre chemise 25 comportant un logement en creux 28 de forme cylindrique de révolution d'une section sensiblement complémentaire de la section de l'arbre 27 de façon que ce dernier puisse pénétrer dans le logement en creux 28 et que l'on obtienne ainsi une paumelle et un gond aptes à pivoter l'un dans l'autre, de la même façon que pour les charnières de l'art antérieur.A jacket 25, 26 is plugged into each through hole 6, 7, one 26 of these shirts comprising an emerging rotation shaft 27 and the other jacket 25 comprising a hollow housing 28 of cylindrical shape of revolution of a section substantially complementary to the section of the shaft 27 so that the latter can penetrate into the hollow housing 28 and so that one obtains a hinge and a hinge capable of pivoting one in the other, in the same way as for the hinges of the prior art.

Sur chaque pièce, sont aussi réalisés des moyens qui permettent de la fixer sur un support comme le châssis d'une fermeture ou la fermeture elle-même, soit un volet, une fenêtre, etc, par exemple des orifices pratiqués dans les parties de parois 8, 9.On each part, means are also made which allow it to be fixed on a support such as the frame of a closure or the closure itself, ie a shutter, a window, etc., for example orifices made in the parts of the walls. 8, 9.

La structure de l'élément 1 décrite ci-avant est très avantageuse car elle permet de réaliser très facilement des charnières d'un coût de revient très inférieur à celui des charnières de l'art antérieur, notamment pour les raisons suivantes:The structure of the element 1 described above is very advantageous because it makes it very easy to produce hinges with a cost price much lower than that of the hinges of the prior art, in particular for the following reasons:

Du fait de la forme cylindrique de la surface latérale 13 du corps unitaire 2, l'élément 1 peut facilement être obtenu dans un profilé de grande longueur. en étant en outre assuré que les paumelles et les gonds qui pourront être débités dans ce profilé seront en nombre égal.Due to the cylindrical shape of the lateral surface 13 of the unitary body 2, the element 1 can easily be obtained in a profile of great length. being further assured that the hinges and the hinges that can be cut in this profile will be of equal number.

Pour obtenir chaque élément 1, il suffit en effet de découper ces profilés suivant des plans perpendiculaires à la génératrice de la surface cylindrique 13 et distants l'un de l'autre d'une longueur égale à celle, entre leurs bords opposés 14-17 et 18-21, des parties d'extrémités 4, 5 et des parties de parois 8, 9. La portion de paroi 10 peut être obtenue en pratiquant, par exemple, deux saignées 30, 31 découpées suivant une même génératrice comme ci-après. Avantageusement, ces deux saignées ont des longueurs égales pour donner au corps unitaire 2 un maximum de rigidité afin, par exemple, de faciliter sa manutention, notamment lors du traitement de surface auquel il doit généralement être soumis. De ce fait, la portion de paroi 10 est sensiblement située à égale distance des bords opposés 15-16 et 19-20 des parties de parois 8, 9.To obtain each element 1, it suffices to cut these sections along planes perpendicular to the generatrix of the cylindrical surface 13 and distant from each other by a length equal to that, between their opposite edges 14-17 and 18-21, end parts 4, 5 and wall parts 8, 9. The wall portion 10 can be obtained by making, for example, two grooves 30, 31 cut along the same generatrix as below . Advantageously, these two grooves have equal lengths to give the unitary body 2 maximum rigidity in order, for example, to facilitate its handling, in particular during the surface treatment to which it must generally be subjected. As a result, the wall portion 10 is substantially located at an equal distance from the opposite edges 15-16 and 19-20 of the wall portions 8, 9.

Bien entendu. les deux saignées 30, 31 peuvent être obtenues simultanément, au moyen d'une seule opération de presse. Cette réalisation est notamment avantageuse quand le profilé est en un matériau comme de l'aluminium. De plus, quand les moyens pour fixer les paumelles et les gonds sur leurs supports respectifs sont constitués par des orifices pratiqués dans les parties de parois 8. 9, ils peuvent être réalisés en même temps que les deux saignées. au moyen de la même et unique presse, ce qui limite encore le nombre d'opérations de fabrication.Of course. the two grooves 30, 31 can be obtained simultaneously, by means of a single press operation. This achievement is particularly advantageous when the profile is made of a material such as aluminum. In addition, when the means for fixing the hinges and the hinges on their respective supports are constituted by orifices made in the wall parts 8, 9, they can be produced at the same time as the two grooves. using the same single press, which further limits the number of manufacturing operations.

La structure selon l'invention de l'élément 1, outre le fait qu'elle permet de réaliser un nombre important de pièces "paumelles" et "gonds" avec un nombre réduit d'opérations et d'apparier parfaitement les deux pièces d'une même charnière, permet également de faire subir à ces deux pièces, puisqu'elles demeurent reliées entre elles par la portion de paroi 10, le même traitement de surface par exemple.The structure according to the invention of element 1, in addition to the fact that it makes it possible to produce a large number of "hinge" and "hinge" parts with a reduced number of operations and to perfectly match the two parts the same hinge also allows these two parts to be subjected, since they remain connected to each other by the wall portion 10, the same surface treatment for example.

De ce fait, dans cette phase de fabrication également le nombre d'opérations est réduit, notamment le nombre de manutentions, et, de plus, les deux pièces traitées ensemble auront rigoureusement le même aspect, la même qualité de surface, ce qui peut présenter un avantage sur le plan esthétique.Therefore, in this manufacturing phase also the number of operations is reduced, in particular the number of handling, and, moreover, the two parts treated together will have rigorously the same appearance, the same quality of surface, which can present an aesthetic advantage.

A la description ci-dessus. il apparaît que l'élément selon l'invention est un perfectionnement avantageux par rapport aux éléments connus de l'art antérieur, notamment pour la réalisation de charnières.In the description above. it appears that the element according to the invention is an advantageous improvement over the elements known from the prior art, in particular for the production of hinges.
