Description

L'invention concerne un boîtier délimité par une paroi et comprenant une ouverture, un rebord entourant l'ouverture, une porte pour fermer l'ouverture, montée à pivotement le long dudit rebord 40 autour d'un axe, un premier élément de charnière monté sur le rebord, et un second élément de charnière solidaire de la porte et destiné à coopérer avec le premier élément de charnière.The invention relates to a housing delimited by a wall and comprising an opening, a flange surrounding the opening, a door for closing the opening, pivotally mounted along said flange 40 about an axis, a first hinge element mounted on the rim, and a second hinge element secured to the door and intended to cooperate with the first hinge element.

Le problème que vise à résoudre l'invention est de proposer un boîtier de ce genre, dont le premier élément de charnière peut être rapporté sur le boîtier de façon aisée et par des moyens automatisés, donc sans intervention d'un opérateur.The problem which the invention aims to solve is to propose a box of this kind, the first hinge element of which can be attached to the box in an easy manner and by automated means, therefore without the intervention of an operator.

Selon l'invention, le premier élément de charnière comprend un profilé de section en forme de U présentant une base et deux ailes, l'une des ailes portant des moyens formant charnière, ledit rebord comprend un profilé présentant une base, au moins une première aile s'étendant perpendiculairement à la base, et un premier repli longeant une face de l'aile tournée vers la base, et le premier élément de charnière est logé dans le rebord de façon que sa base s'appuie sur la base du rebord et que son aile éloignée desdits moyens formant charnière s'étende, en étant pincée, entre l'aile du rebord et ledit premier repli.According to the invention, the first hinge element comprises a U-shaped section profile having a base and two wings, one of the wings carrying hinge means, said flange comprises a profile having a base, at least a first wing extending perpendicular to the base, and a first fold along a face of the wing facing the base, and the first hinge element is housed in the rim so that its base rests on the base of the rim and that its wing remote from said hinge means extends, being pinched, between the flange wing and said first fold.

Une telle conception procure un positionnement automatique de l'élément de charnière par rapport au rebord le recevant, facilitant l'automatisation du montage du boîtier dans son ensemble.Such a design provides automatic positioning of the hinge element relative to the flange receiving it, facilitating the automation of assembly of the housing as a whole.

Selon l'invention, un procédé de montage du premier élément de charnière consiste en ce que l'on introduit l'élément de charnière dans le rebord par une extrémité de celui-ci et on le glisse le long du rebord de façon que la base de l'élément de charnière s'appuie sur la base du rebord et que son aile éloignée desdits moyens formant charnière s'étende entre l'aile du rebord et ledit premier repli, et l'on sertit l'élément de charnière sur le rebord en appliquant le repli du rebord sur l'aile de l'élément de charnière.According to the invention, a method of mounting the first hinge element consists in that one introduces the hinge element into the rim by one end of the latter and one slides it along the rim so that the base of the hinge element rests on the base of the rim and its wing remote from said means forming hinge extends between the flange of the flange and said first fold, and the hinge element is crimped on the flange by applying the fold of the flange on the wing of the hinge element.

Sur la figure 1, est représenté un capot 1 de boîte aux lettres constitué d'une tôle mince pliée en forme de U, ce capot comprenant une face supérieure 2 prolongée, le long de deux bords longitudinaux, par deux faces latérales 3, 4. Les faces latérales 3, 4 sont reliées à la face supérieure 2 par un arrondi 10. A deux extrémités du capot 1, chaque face présente, le long d'un bord d'extrémité, un rebord 5 qui s'étend vers l'intérieur du capot, parallèlement à la face considérée.FIG. 1 shows a cover 1 for a letterbox made of a thin sheet folded into a U shape, this cover comprising an upper face 2 extended, along two longitudinal edges, by two lateral faces 3, 4. The lateral faces 3, 4 are connected to the upper face 2 by a rounded 10. At two ends of the cover 1, each face has, along an end edge, a flange 5 which extends inwards of the cover, parallel to the face considered.

La boîte aux lettres comprend encore un fond 6 constitué lui aussi d'une tôle pliée en forme de U de façon à définir une face inférieure 7, une face avant 8 et une face arrière 9. La face inférieure 7 présente deux bords longitudinaux, et deux bords d'extrémité à partir desquels s'étendent les faces avant 8 et arrière 9.The letterbox also comprises a bottom 6 also consisting of a sheet folded in the shape of a U so as to define a lower face 7, a front face 8 and a rear face 9. The lower face 7 has two longitudinal edges, and two end edges from which extend the front 8 and rear 9 faces.

La face avant 8 du fond 6 présente une ouverture 11 s'étendant sur une majeure partie de sa surface de façon que cette face avant constitue un cadre. L'ouverture 11 est entourée d'un rebord 18 perpendiculaire à la face avant 8. La face avant 8 et la face arrière 9 du fond 6 présentent, le long de trois côtés libres, un rebord 12 s'étendant perpendiculairement à la face considérée et vers l'extérieur de la boîte aux lettres. Le rebord 12 s'étend sur une largeur supérieure à celle du rebord 18 de l'ouverture 11. Par ailleurs, la face inférieure 7 du fond 6 présente, le long de deux côtés longitudinaux, un rebord 13 s'étendant perpendiculairement à cette face et tourné vers l'extérieur de la boîte aux lettres. Les rebords 5 du capot 1 et ceux 12 du fond 6 présentent une largeur voisine. Comme cela apparaît notamment sur la figure 7, la face avant 8 du fond 6 détermine avec son rebord 12 et celui 18 de l'ouverture 11, une forme de U.The front face 8 of the bottom 6 has an opening 11 extending over a major part of its surface so that this front face constitutes a frame. The opening 11 is surrounded by a rim 18 perpendicular to the front face 8. The front face 8 and the rear face 9 of the bottom 6 have, along three free sides, a rim 12 extending perpendicular to the face considered and out of the mailbox. The rim 12 extends over a width greater than that of the rim 18 of the opening 11. Furthermore, the lower face 7 of the bottom 6 has, along two longitudinal sides, a rim 13 extending perpendicular to this face and turned to the outside of the mailbox. The edges 5 of the cover 1 and those 12 of the bottom 6 have a similar width. As appears in particular in FIG. 7, the front face 8 of the bottom 6 determines with its rim 12 and that 18 of the opening 11, a shape of U.

Sur la figure 5, est représenté un élément de charnière 14 constitué d'une cornière comprenant deux ailes 15, 16. L'aile 15 s'étend, d'un côté de l'élément de charnière 14, au-delà de l'aile 16 selon un prolongement 17. Ce prolongement présente un arrondi 19 d'un côté de l'aile 15 tourné vers l'aile 16.In FIG. 5, an element of hinge 14 consisting of an angle including two wings 15, 16. The wing 15 extends, on one side of the hinge element 14, beyond the wing 16 in an extension 17. This extension has a round 19 on one side of the wing 15 facing the wing 16.

A partir d'un bord longitudinal de l'aile 15 le plus éloigné de l'aile 16, s'étendent deux pattes 21, 22 parallèlement à l'aile 16. Les pattes 21, 22 s'étendent sur une majeure partie de la longueur de l'élément de charnière 14, et s'étendent en largeur sur une distance correspondant approximativement à la largeur de l'aile 16. Les pattes 21, 22 sont séparées l'une de l'autre par un espace 23. Vu en section au niveau d'une patte, l'élément de charnière 14 a donc une forme de U.From a longitudinal edge of the wing 15 furthest from the wing 16, extend two legs 21, 22 parallel to the wing 16. The legs 21, 22 extend over a major part of the length of the hinge element 14, and extend in width over a distance corresponding approximately to the width of the wing 16. The legs 21, 22 are separated from each other by a space 23. Seen at section at a tab, the hinge element 14 therefore has a U shape.

Un bord longitudinal libre de chaque patte 21, 22 est replié sur lui même de façon à constituer une douille de section circulaire, située sur un côté de la patte tourné vers l'aile 16 de l'élément de charnière 14. L'élément de charnière 14 s'étend sur une longueur sensiblement égale à celle d'un coté de la face avant 8 du fond 6, c'est-à-dire encore sur une longueur égale à celle d'un petit côté des faces latérales 3, 4 du capot 1.A free longitudinal edge of each tab 21, 22 is folded back on itself so as to constitute a socket of circular section, located on one side of the tab facing the wing 16 of the hinge element 14. The element of hinge 14 extends over a length substantially equal to that of one side of the front face 8 of the bottom 6, that is to say again over a length equal to that of a short side of the side faces 3, 4 cover 1.

Le montage de la boîte aux lettres va maintenant être exposé. Dans une première phase, on incline la face avant 8 et la face arrière 9 du fond 6 vers l'intérieur, par pivotement autour de leur bord par lequel elles sont reliées à la face inférieure 7, sur un angle par exemple égal à environ 15°. On coiffe alors le fond 6 en ramenant par le dessus le capot 1 de façon que les rebords 5 du capot soient en face des rebords 12 du fond. On ramène alors la face avant 8 et la face arrière 9 du fond 6 dans leur position d'origine en les faisant pivoter selon les flèches 26 de la figure 3, ce qui a pour effet d'introduire les rebords 12 du fond 6 entre les rebords 5 du capot 1 et les faces qui portent ces derniers. Une situation intermédiaire est représentée sur la figure 7, où le rebord 12 de la face avant 8 du fond n'est pas encore introduit entre le rebord 5 de la face latérale 4 du capot et cette même face. Les figures 4 et 8 illustrent au contraire une situation finale.The assembly of the mailbox will now be explained. In a first phase, the front face 8 and the rear face 9 of the bottom 6 are tilted inwards, by pivoting around their edge by which they are connected to the bottom face 7, at an angle for example equal to about 15 °. The bottom 6 is then capped by bringing the cover 1 from above so that the edges 5 of the cover are opposite the edges 12 of the bottom. The front face 8 and the rear face 9 of the bottom 6 are then brought back to their original position by rotating them according to the arrows 26 in FIG. 3, which has the effect of introducing the edges 12 of the bottom 6 between the edges 5 of the cover 1 and the faces which carry the latter. An intermediate situation is shown in Figure 7, where the edge 12 of the front face 8 of the bottom is not yet introduced between the rim 5 of the side face 4 of the cover and this same face. Figures 4 and 8 illustrate instead a final situation.

Ensuite,la boîte aux letres étant retournée, l'élément de charnière 14 est glissé par au-dessus dans celle-ci à partir de la face inférieure 7 du fond 6, c'est-à-dire selon la flèche 27 de la figure 5 en direction de la boîte de la figure 4. Plus précisément, l'élément de charnière 14 est glissé de façon à être logé dans un côté du cadre constitué par la face avant 8 du fond 6, de manière que les pattes 21, 22, l'aile 15 et l'aile 16 de l'élément de charnière s'appuient respectivement sur le rebord 18 de l'ouverture 11, la face avant 8, et le rebord 12 du capot. L'élément de charnière 14 est glissé dans la boîte aux lettres jusqu'à ce que son arrondi 19 vienne buter contre l'arrondi correspondant 10 du capot. On notera par ailleurs qu'il subsiste un jeu 30 entre le rebord 5 du capot et l'aile 16 de l'élément de charnière, de même qu'il subsiste un jeu entre les autres rebords 5 du capot et les rebords correspondants 12 du fond 6.Then, the letter box being turned over, the hinge element 14 is slid from above into it from the bottom face 7 of the bottom 6, that is to say according to arrow 27 in the figure 5 in the direction of the box of FIG. 4. More specifically, the hinge element 14 is slid so as to be housed in one side of the frame constituted by the front face 8 of the bottom 6, so that the legs 21, 22 , the wing 15 and the wing 16 of the hinge element bear respectively on the rim 18 of the opening 11, the front face 8, and the rim 12 of the cover. The hinge element 14 is slid into the letterbox until its round 19 abuts against the corresponding round 10 of the cover. Note also that there is a clearance 30 between the flange 5 of the cover and the flange 16 of the hinge element, just as there remains a clearance between the other flanges 5 of the cover and the corresponding flanges 12 of the background 6.

Ensuite, le capot 1 est serti sur le fond 6 en appliquant les rebords 5 du premier sur les rebords 12 du second et, dans le cas de l'élément de charnière 14, en appliquant le rebord 5 du capot sur l'aile 16 de l'élément de charnière (selon la flèche 32 de la figure 8), cette opération s'effectuant de façon connue en soi au moyen de mâchoires de sertissage enserrant de part et d'autre les rebords à sertir.Then, the cover 1 is crimped on the bottom 6 by applying the edges 5 of the first on the edges 12 of the second and, in the case of the hinge element 14, by applying the edge 5 of the cover on the wing 16 of the hinge element (according to arrow 32 in FIG. 8), this operation being carried out in a manner known per se by means of crimping jaws enclosing on either side the edges to be crimped.

Comme cela apparaît sur la figure 9, l'aile 16 de l'élément de charnière 14 et le rebord 12 porté par la face avant 8 du fond 6 sont donc simultanément pincés par le rebord 5 de la face latérale 4 du capot.As shown in FIG. 9, the wing 16 of the hinge element 14 and the flange 12 carried by the front face 8 of the bottom 6 are therefore simultaneously pinched by the flange 5 of the side face 4 of the cover.

On notera que l'élément de charnière 14 est parfaitement guidé et positionné par la forme en U définie par les rebords 18, 12 de la face avant 8 du fond 6, ce qui permet d'envisager un montage totalement automatisé de l'élément de charnière 14.It will be noted that the hinge element 14 is perfectly guided and positioned by the U shape defined by the flanges 18, 12 of the front face 8 of the bottom 6, which makes it possible to envisage a fully automated mounting of the element of hinge 14.

En complément de cette fixation par sertissage, on peut prévoir, si désiré, un soudage par points,soit le long des rebords sertis en ce qui concerne les rebords de la face supérieure 2 du capot, soit le long de l'aile 15 en ce qui concerne l'élément de charnière 14. Sur les figures 6 et 8, ces endroits sont repérés par les flèches 31.In addition to this fixing by crimping, provision may be made, if desired, for spot welding, either along the crimped edges as regards the edges of the upper face 2 of the cover, or along the wing 15 in that which relates to the hinge element 14. In FIGS. 6 and 8, these places are identified by the arrows 31.

De façon comme en soi, la porte de la boîte aux lettres porte deux douilles 33 (figure 10) destinées à être disposées de part et d'autre de celles 24, 25 de l'élément de charnière 14, un axe non représenté traversant chaque douille.As in itself, the door of the letterbox carries two sockets 33 (FIG. 10) intended to be arranged on either side of those 24, 25 of the hinge element 14, an axis not shown passing through each socket.

Une seconde forme de réalisation est représentée sur les figures 11 à 13. Elle concerne une boîte aux lettres dont la face avant, formant cadre, est d'une seule pièce avec ses faces latérales telles que 41 (figure 12) et constitue un rebord 40 de celles-ci. Ce rebord est en forme générale de U tourné vers l'avant de la boîte, et présentant une base 42 et deux ailes 43, 44. L'aile 43 constitue un repli de la face latérale 41 de la boîte et s'étend donc vers l'arrière de la boîte en étant accolée à la face latérale. L'autre aile 44 porte un repli 45 s'étendant donc vers l'arrière de la boîte, en face mais à quelque distance de cette aile, sur une longueur inférieure à celle de l'aile.A second embodiment is shown in Figures 11 to 13. It relates to a mailbox whose front face, forming a frame, is in one piece with its lateral faces such as 41 (Figure 12) and constitutes a flange 40 of these. This rim is generally U-shaped facing the front of the box, and having a base 42 and two wings 43, 44. The wing 43 constitutes a fold of the lateral face 41 of the box and therefore extends towards the back of the box being attached to the side face. The other wing 44 carries a fold 45 therefore extending towards the rear of the box, opposite but at some distance from this wing, over a length less than that of the wing.

L'élément de charnière 46 représenté sur la figure 11 diffère essentiellement de celui de la figure 5 en ce que les pattes 47, 48 et leurs douilles 51, 52 sont portées par l'aile opposée 54 de l'élément de charnière, les douilles étant disposées sur une face de l'aile 54 la plus éloignée de l'autre aile 53, c'est-à-dire à l'extérieur de l'élément de charnière.The hinge element 46 shown in FIG. 11 differs essentially from that of FIG. 5 in that the legs 47, 48 and their sockets 51, 52 are carried by the opposite wing 54 of the hinge element, the sockets being arranged on one side of the wing 54 furthest from the other wing 53, that is to say outside of the hinge element.

En ce qui concerne les dimensions de l'élément de charnière 46, son aile 53 opposée aux pattes 47, 48 est de largeur sensiblement égale à celle de l'aile 44 du rebord de boîte 40 tandis que son autre aile 54 est de largeur égale à environ la moitié de la base 42 du rebord de boîte 40. Par ailleurs, les pattes 47, 48 s'étendent sur une largeur sensiblement égale à celle de l'aile 43 du rebord de boîte 40.As regards the dimensions of the hinge element 46, its wing 53 opposite the legs 47, 48 is of width substantially equal to that of the wing 44 of the box flange 40 while its other wing 54 is of equal width at about half of the base 42 of the box flange 40. Furthermore, the tabs 47, 48 extend over a width substantially equal to that of the wing 43 of the box edge 40.

Comme pour la forme de réalisation précédente, l'élément de charnière 46 est glissé dans le rebord de boîte 40, son aile 53 opposée aux pattes 47, 48 étant logée avec jeu entre l'aile 44 du rebord de boîte 40 et son repli 44. Un sertissage est alors obtenu, par pincement selon les flèches 55 de la figure 13.As for the previous embodiment, the hinge element 46 is slid into the box flange 40, its wing 53 opposite the legs 47, 48 being housed with clearance between the wing 44 of the box flange 40 and its fold 44 A crimping is then obtained, by pinching according to the arrows 55 in FIG. 13.

Avant montage et dans le cas où l'on désire un renforcement de l'assemblage, l'aile 54 de l'élément de charnière 46 portant les pattes 47, 48 peut être recouverte, sur une face extérieure, d'une couche de colle 56 (figure 12) pour son assemblage avec la base 42 du rebord. Ce type de renforcement convient particulièrement bien dans le cas où les pièces de la boîte aux lettres portent déjà, avant assemblage, leur traitement de finition.Before mounting and if it is desired to reinforce the assembly, the wing 54 of the hinge element 46 carrying the tabs 47, 48 can be covered, on an external face, with a layer of adhesive 56 (Figure 12) for its assembly with the base 42 of the rim. This type of reinforcement is particularly suitable in the case where the parts of the mailbox already carry, before assembly, their finishing treatment.

Sur la figure 13 apparaîssent la porte 57 de la boîte et l'axe 58 destiné à sa fixation sur cette dernière.In Figure 13 appear the door 57 of the box and the axis 58 intended for its attachment to the latter.
