Abstract

The device consists of a mobile part (1) coupled to a lateral skirt (50) on the cover (5), and a fixed part (30, 31) comprising a head (31) and a lug (30) mounted on the container which is to be covered by the cover (5). The mobile part (1) in the form of a flange comprises a central projection (12) with an enlarged end (18) which, after passing through a hole (51) in the skirt (50), enters a hollow bearing (35) in the fixed part (31). The cylindrical central projection (12) has a diametral slit (19) enabling its enlarged end (18) to pass through the bearing (35). When it emerges from the side opposite the bearing (35), this end provides a rotating engagement by catching between the fixed part (30-31) and the mobile part (1). <IMAGE>

Description

L'invention concerne des dispositifs de support du type charnières à montage latéral pour capot ou couvercle pivotant autour d'un axe horizontal proche de son extrémité arrière, comprenant chacun un ressort calibré de façon à équilibrer, quelle que soit son orientation, le poids du capot en porte-à-faux par rapport à cet axe.The invention relates to support devices of the hinge type with lateral mounting for hood or cover pivoting about a horizontal axis close to its rear end, each comprising a spring calibrated so as to balance, whatever its orientation, the weight of the hood cantilevered with respect to this axis.

De telles charnières à équilibrage par ressort de torsion hélicoidal sont généralement respectivement montées sur des parois latérales opposées, verticalement orientées de la jupe d'un capot. Ils comprennent chacun une tête en forme de coupelle à paroi latérale cylindrique, solidaire d'une patte de fixation qui peut être monté sur les parois latérales opposées du boîtier contenant l'appareil à recouvrir par le capot pivotable. Un tel appareil est, par exemple, constitué par un lecteur de disque à plateau tournant horizontal qui doit être rendu accessible notamment pour la pose ou le retrait du disque portant un enregistrement, par l'ouverture du capot pivotant.Such hinges with helical torsion spring balancing are generally respectively mounted on opposite side walls, vertically oriented from the skirt of a cover. They each comprise a cup-shaped head with a cylindrical side wall, integral with a fixing lug which can be mounted on the opposite side walls of the housing containing the device to be covered by the pivotable cover. Such an apparatus is, for example, constituted by a disc player with a horizontal turntable which must be made accessible in particular for the installation or removal of the disc carrying a recording, by opening the pivoting cover.

La tête d'un type connu de charnière est composée d'une paroi latérale cylindrique, obturée sur l'un de ses côtés par un fond plat en forme de disque muni d'une ouverture centrale. Cette ouverture centrale sert à loger un axe en porte-à-faux de telle sorte qu'il ne puisse pas se déplacer axialement. A cette fin, il comprend à l'un de ses bouts, un épaulement qui est appliqué contre la face extérieure du fond plat. Un cylindre est emmanché sur l'axe et rendu solidaire de celui-ci par collage, sertissage, rivetage ou surmoulage, par exemple, de telle sorte que l'une de ses extrémités soit appliquée contre la face intérieure de ce fond qui est ainsi enserré des deux côtés. L'autre extrémité du cylindre solidaire de l'axe, est solidaire d'un disque circulaire qui est normal à ce dernier et dont la face opposée au fond de la tête est située dans le plan du bord de la paroi latérale de celle-ci. Entre les faces intérieures respectives de cette dernière, du fond et du disque, et la surface du cylindre emmanché sur l'axe, il est ménagée une cavité annulaire permettant de loger un ressort de torsion de forme hélicoïdale, par exemple. Celle des extrémités du ressort qui est au voisinage du fond est repliée de façon à présenter un bout radial qui permet son ancrage par insertion dans une ouverture pratiquée dans la paroi latérale de la tête. L'autre extrémité du ressort est repliée de manière à former un bout axial qui s'insère dans un trou pratiqué dans la circonférence du disque. On notera ici que les sens de l'enroulement du ressort de la charnière de l'un des côtés (gauche) doit être inversé par rapport à celui de la charnière de l'autre côté (droite), pour que les deux charnières respectivement situées des côtés opposés de l'appareil, avec leurs disques polarisés par les ressorts, tournés vers l'extérieur et réunis ensemble à travers le capot, puissent le faire pivoter dans le même sens. Le mouvement pivotant de chacune des charnières est limité par deux butées de telle sorte que l'angle de pivotement possible soit à 90 degrés (c'est-à-dire entre des positions horizontale et verticale du capot).The head of a known type of hinge is composed of a cylindrical side wall, closed on one of its sides by a flat bottom in the form of a disc provided with a central opening. This central opening serves to accommodate a cantilevered axis so that it cannot move axially. To this end, it includes at one of its ends, a shoulder which is applied against the outer face of the flat bottom. A cylinder is fitted on the axis and made integral with it by gluing, crimping, riveting or overmolding, for example, so that one of its ends is applied against the inner face of this base which is thus clamped on both sides. The other end of the cylinder integral with the axis, is integral with a circular disc which is normal to the latter and whose face opposite the bottom of the head is located in the plane of the edge of the wall side of it. Between the respective inner faces of the latter, of the bottom and of the disc, and the surface of the cylinder fitted on the axis, an annular cavity is provided, making it possible to accommodate a torsion spring of helical shape, for example. That of the ends of the spring which is in the vicinity of the bottom is folded so as to have a radial end which allows its anchoring by insertion into an opening made in the side wall of the head. The other end of the spring is folded back so as to form an axial end which fits into a hole made in the circumference of the disc. It will be noted here that the directions of winding of the hinge spring on one side (left) must be reversed with respect to that of the hinge on the other side (right), so that the two hinges respectively located opposite sides of the device, with their disks polarized by the springs, turned outwards and joined together through the cover, can rotate it in the same direction. The pivoting movement of each of the hinges is limited by two stops so that the possible pivoting angle is 90 degrees (that is to say between the horizontal and vertical positions of the cover).

Le disque est muni sur son pourtour de quatre saillies cylindriques ou pions qui sont situés symétriquement à l'axe de pivotement, dont deux diamétralement opposés sont percées de trous centraux pour l'ancrage du bout axial du ressort et dont deux autres sont munis de trous taraudés qui leur permettent de recevoir les vis de fixation du capot. La partie arrière du capot est percée de quatre trous qui permettent l'insertion de ces pions dont la hauteur est au plus égale à l'épaisseur du capot. Le montage des charnières sur le capot est effectué à l'aide d'un flasque en forme de disque dont le diamètre est sensiblement égal à celui de la tête cylindrique et qui est percé de deux trous diamétralement opposés qui permettent respectivement le passage de deux vis vers les pions taraudés, engagés dans deux des trous du capot. Le serrage de ces vis permet de serrer l'arrière de chaque paroi latérale du capot entre les faces en regard respectifs du disque pivotant et du flasque.The disc is provided on its periphery with four cylindrical projections or pins which are located symmetrically to the pivot axis, two diametrically opposed holes of which are drilled with central holes for anchoring the axial end of the spring and two others of which are provided with holes threaded which allow them to receive the hood fixing screws. The rear part of the cover is pierced with four holes which allow the insertion of these pins whose height is at most equal to the thickness of the cover. The mounting of the hinges on the cover is carried out using a disc-shaped flange whose diameter is substantially equal to that of the cylindrical head and which is pierced by two diametrically opposite holes which allow the passage of two screws respectively. towards the threaded pins, engaged in two of the holes in the cover. The tightening of these screws makes it possible to tighten the rear of each side wall of the cover between the respective opposite faces of the pivoting disc and of the flange.

Dans une charnière de l'état de la technique décrit ci-dessus, la patte de fixation et la tête qui sont solidaires, leurs rebords, saillies et trous sont réalisées en une seule pièce par découpage et emboutissage d'une tôle métallique épaisse (1,5 - 2mm). L'axe avec son épaulement et le ressort sont également en métal. L'ensemble solidaire du cylindre et du disque ainsi que le flasque sont, par exemple, réalisés par moulage de matériaux plastiques. Le montage du disque sur l'axe après l'insertion de celui-ci dans l'ouverture centrale du fond de la tête avec le ressort déjà placé, ancré et tendu dans la cavité annulaire, est une opération relativement complexe nécessitant un outillage sophistiqué et/ou automatisé, de sorte que sa fabrications doit être réalisée en grande série pour être rentable. En outre, deux vis sont nécessaires pour assurer le montage du capot et du flasque sur le disque. Ces vis peuvent être taraudeuses et les pions dans lesquels elles sont vissées peuvent être percés sans filet intérieur pour réaliser une faible économie.In a hinge of the prior art described above, the fixing lug and the head which are integral, their edges, projections and holes are produced in one piece by cutting and stamping a thick metal sheet (1 , 5 - 2mm). The axle with its shoulder and the spring are also made of metal. The integral assembly of the cylinder and the disc as well as the flange are, for example, produced by molding of plastic materials. The mounting of the disc on the axis after the insertion of this one in the central opening of the bottom of the head with the spring already placed, anchored and tensioned in the annular cavity, is a relatively complex operation requiring sophisticated tools and / or automated, so that its production must be carried out in large series to be profitable. In addition, two screws are necessary to ensure the mounting of the cover and the flange on the disc. These screws can be tapping and the pins in which they are screwed can be drilled without an internal thread to achieve low savings.

La charnière, objet de la présente invention, permet de réaliser d'importantes économies de main d'oeuvre, lors de sa fabrication, d'une part, et lors de son montage, d'autre part. Tout en réalisant les mêmes fonctions que celle de l'état de la technique, elle n'est composée que de trois pièces dont seul le ressort est métallique, l'axe, le disque, le flasque et son moyeu de fixation ne constituant qu'une pièce unique en matériau plastique obtenue par moulage. Son volume étant sensiblement le même que celui de la charnière classique décrite ci-dessus, son poids est notablement, inférieur tout en lui assurant une rigidité et une résistance mécaniques satisfaisantes.The hinge, object of the present invention, allows significant savings in labor, during its manufacture, on the one hand, and during its assembly, on the other hand. While performing the same functions as that of the prior art, it is only composed of three parts of which only the spring is metallic, the axis, the disc, the flange and its fixing hub constituting only a single piece of plastic material obtained by molding. Its volume being substantially the same as that of the conventional hinge described above, its weight is notably, less while providing it with satisfactory rigidity and mechanical strength.

Suivant l'invention, un dispositif de support pivotant ou charnière à montage latéral pour capot ou couvercle, dont un est monté de chaque côté de l'appareil ou du boîtier que celui-ci est destiné à recouvrir, au voisinage de son bord arrière et de telle sorte que l'axe de pivotement du capot soit parallèle à ce dernier, chacun des dispositifs ou charnières comprenant une partie fixe, une partie mobile enserrant entre elles une jupe latérale du capot ou couvercle, pourvue de trous destinés au passage des éléments de liaison entre les différentes parties, est principalement caractérisé en ce que la partie fixe comporte un palier cylindrique creux, de longueur et de diamètre déterminés, dont l'axe est normal à la jupe et en ce que la partie mobile comporte une saillie centrale sensiblement cylindrique traversant la jupe par l'intermédiaire d'un trou ainsi que le palier, et comportant en bout des élargissements à bout arrondi ou tronçonique sur ses côtés diamètralement opposés et une fente orientée perpendiculairement à ces élargissements afin de faciliter leur passage à travers le palier dont ils émergent de l'autre côté en y asurant une liaison pivotante entre les parties mobile et fixe par encliquetage.According to the invention, a pivoting support device or hinge with lateral mounting for hood or cover, one of which is mounted on each side of the apparatus or of the housing that the latter is intended to cover, in the vicinity of its rear edge and such that the pivot axis of the cover is parallel to the latter, each of the devices or hinges comprising a fixed part, a movable part enclosing between them a side skirt of the cover or cover, provided with holes for the passage of the connecting elements between the different parts, is mainly characterized in that the fixed part comprises a hollow cylindrical bearing, of determined length and diameter, the axis of which is normal to the skirt and in that the movable part has a substantially cylindrical central projection passing through the skirt via a hole as well as the bearing, and having at the end enlargements with rounded or sectional ends on its diametrically opposite sides and a slot oriented perpendicular to these enlargements so facilitate their passage through the bearing from which they emerge on the other side by providing a pivoting connection between the movable and fixed parts by snap-fastening.

Sur les figures 1, 2 et 3, on a respectivement représenté en plan et en coupe selon AA et BB, un flasque ou disque plat circulaire 1 constituant la partie de la charnière latérale qui est montée à l'extérieur de la jupe. Il comprend une face extérieure 10 sensiblement plate et une face intérieure également plate 11 et pourvue de trois saillies (ou pions), normalement orientées 12, 13 et 14 et solidaires, dont la première 12 est située centralement et dont les deux autres 13 et 14 sont respectivement disposées des côtés diamétralement opposés à la première 12.In Figures 1, 2 and 3, there is shown respectively in plan and in section along AA and BB, a flange or circular flat disc 1 constituting the part of the lateral hinge which is mounted outside the skirt. It comprises an appreciably flat outer face 10 and an equally flat inner face 11 and provided with three projections (or pins), normally oriented 12, 13 and 14 and integral, the first 12 of which is located centrally and the other two of which 13 and 14 are respectively arranged on the diametrically opposite sides of the first 12.

La première saillie 12 ou pion, sensiblement en forme de tige cylindrique, est située au milieu (centre) de la face interne 11 du disque. Elle est composée d'une première partie cylindrique 15 de diamètre prédéterminé, suivie d'une seconde partie 15, qui sert d'axe de pivotement au flasque 1 et qui est terminée par un élargissement en forme de tête 17 dont la face tournée vers le disque est radiale.The first projection 12 or pin, substantially in the form of a cylindrical rod, is located in the middle (center) of the internal face 11 of the disc. It is composed of a first cylindrical part 15 of predetermined diameter, followed by a second part 15, which serves as a pivot axis for the flange 1 and which is terminated by a head-shaped enlargement 17 the face of which faces towards the disc is radial.

La face opposée de cette tête forme un bout 18 qui se rétrécit, de forme arrondie ou tronçonique.The opposite face of this head forms a tip 18 which narrows, of rounded or sectional shape.

Le bout 18 et la seconde partie cylindrique 16 sont séparés en deux par une fente diamétrale 19 sur une majeure partie de la hauteur de cette dernière 16 de façon à permettre le fléchissement élastique des deux parties ainsi séparées l'une vers l'autre. Ce fléchissement permet, lors de l'assemblage de la charnière, de faire pénétrer le bout élargi 18 de la seconde partie cylindrique 16 dans un palier creux dont le diamètre intérieur n'est au plus que légèrement supérieur au diamètre extérieur de cette dernière.The end 18 and the second cylindrical part 16 are separated in two by a diametrical slot 19 over a major part of the height of the latter 16 so as to allow the elastic bending of the two parts thus separated towards one another. This deflection allows, during assembly of the hinge, to penetrate the enlarged end 18 of the second cylindrical part 16 in a hollow bearing whose inner diameter is at most only slightly greater than the outer diameter of the latter.

On remarquera ici que le bout élargi 18 présente dans le sens de la fente 19, sensiblement la même dimension que le diamètre de la seconde partie cylindrique 16 de la saillie 12 ou que le diamètre intérieur du palier qu'il doit traverser de part en part, et dans le sens normal à cette fente 19, une dimension qui est au plus égale à la somme de ce diamètre et de la largeur de cette dernière, et sensiblement égale au diamètre de la première partie cylindrique 15.It will be noted here that the enlarged end 18 has in the direction of the slot 19, substantially the same dimension as the diameter of the second cylindrical part 16 of the projection 12 or that the internal diameter of the bearing which it must pass right through. , and in the normal sense to this slot 19, a dimension which is at most equal to the sum of this diameter and the width of the latter, and substantially equal to the diameter of the first cylindrical part 15.

La seconde saillie 13 (ou pion) représentée en haut entre le centre et le bord de la face intérieure 11 du disque 1, est de forme cylindrique et de hauteur au plus égale à l'épaisseur de la jupe du couvercle ou capot (non représentés), ce qui est également le cas en ce qui concerne la première partie cylindrique 15 de la première saillie 12 dont le diamètre est au moins égal à la plus grande dimension radiale de la tête élargie 17. Cette seconde saillie 13 coopère avec la première 12, centrale en pénétrant lors de l'assemblage de la charnière, respectivement dans deux ouvertures de la jupe latérale du capot qui y ont été pratiqués à cet effet, afin de rendre cette jupe sensiblement fixe par rapport au flasque ou disque 1.The second projection 13 (or pin) shown above between the center and the edge of the inner face 11 of the disc 1, is of cylindrical shape and height at most equal to the thickness of the skirt of the cover or cover (not shown ), which is also the case with regard to the first cylindrical part 15 of the first projection 12 whose diameter is at least equal to the largest radial dimension of the enlarged head 17. This second projection 13 cooperates with the first 12 , central when penetrating during assembly of the hinge, respectively into two openings in the side skirt of the cover which have been made therein for this purpose, in order to make this skirt substantially fixed relative to the flange or disc 1.

La troisième saillie 14 (ou pion) présente une section, par exemple, sensiblement ovale ou elliptique (ou même rectangulaire), avec son grand axe orienté radialement et une hauteur notablement supérieure à l'épaisseur de la jupe latérale du capot pour en émerger du côté intérieur. Elle (14) est munie d'une gorge ou fente 140 en forme d'arc de cercle dont le centre est situé sur l'axe géométrique commun du disque 1 et de la saillie centrale 12 et au milieu de cette gorge 140 d'une ouverture circulaire 141 parallèle à cet axe et qui la traverse sensiblement de part en part. La profondeur de cette gorge 140 est choisie, de préférence, inférieure à la différence entre la hauteur de la saillie 14 et l'épaisseurde la jupe, de telle sorte que son fond soit situé légèrement vers l'extérieur de la face intérieure de celle-ci, lorsque la charnière y est montée.The third projection 14 (or pin) has a section, for example, substantially oval or elliptical (or even rectangular), with its major axis oriented radially and a height significantly greater than the thickness of the side skirt of the cover to emerge from it. interior side. It (14) is provided with a groove or slot 140 in the form of an arc of a circle, the center of which is located on the common geometric axis of the disc 1 and of the central projection 12 and in the middle of this groove 140 with a circular opening 141 parallel to this axis and which passes through it substantially right through. The depth of this groove 140 is preferably chosen to be less than the difference between the height of the projection 14 and the thickness of the skirt, so that its bottom is located slightly towards the outside of the inner face of the latter. ci, when the hinge is fitted.

Cette troisième saillie 14 sert, d'une part, à l'ancrage ou la fixation d'une extrémité d'un ressort de torsion décrit plus loin et d'autre part, de butée pouvant déterminer les limites du pivotement du capot.This third projection 14 serves, on the one hand, for anchoring or fixing one end of a torsion spring described below and, on the other hand, as a stop which can determine the limits of the pivoting of the cover.

On notera également que pour faire pivoter le capot en même temps que le flasque 1, il suffit, outre la saillie centrale 12 formant axe, une saillie excentrée unique pouvant exercer des fonctions multiples, telle que la troisième saillie 14 (ou téton). On peut donc omettre la seconde saillie 13 qui lui est diamétralement opposée.Note also that to rotate the cover at the same time as the flange 1, it suffices, in addition to the central projection 12 forming an axis, a single eccentric projection that can perform functions multiple, such as the third projection 14 (or nipple). We can therefore omit the second projection 13 which is diametrically opposite to it.

  • Les figures 4 et 5 représentent sensiblement en perspective, respectivement des ressorts d'équilibrage du poids du capot 2G,2D qui servent à le maintenir dans n'importe quelle position entre l'horizontale (fermée) et une proche de la verticale (70-80° par rapport à l'horizontale, ouverte) qui permet l'accès à la surface qu'il recouvre dans la première.FIGS. 4 and 5 represent substantially in perspective, respectively, springs for balancing the weight of the hood 2G, 2D which serve to maintain it in any position between the horizontal (closed) and one close to the vertical (70- 80 ° to the horizontal, open) which allows access to the surface it covers in the first.
  • La figure 4 montre un ressort de torsion 2G destiné à équiper la charnière gauche et comprenant une partie centrale de forme hélicoïdale 20 dont l'extrémité intérieure est prolongée par un repli radial 23 dont la fonction sera expliquée plus loin. L'autre extrémité (extérieure) du ressort 20 est prolongée par un repli dans le sens axial 22 qui est inséré dans le trou 141 du troisième pion 14 du flasque 1, qui sert de point d'ancrage. Le bout de la partie hélicoïdale 20 qui suit ce repli axial 22 prend place dans la gorge 140 en arc de cercle, de façon à limiter le pivotement du ressort 2G autour de l'axe défini par ce trou 141. Le ressort 2G y est montré détendu et sa tension est obtenue par le déplacement de l'extrémité de son repli radial 23 dans le sens des aiguilles d'une montre.FIG. 4 shows a torsion spring 2G intended to equip the left hinge and comprising a central part of helical shape 20 whose inner end is extended by a radial fold 23 whose function will be explained later. The other (outer) end of the spring 20 is extended by a fold in the axial direction 22 which is inserted into the hole 141 of the third pin 14 of the flange 1, which serves as an anchoring point. The end of the helical part 20 which follows this axial fold 22 takes place in the groove 140 in an arc, so as to limit the pivoting of the spring 2G around the axis defined by this hole 141. The spring 2G is shown there relaxed and its tension is obtained by moving the end of its radial fold 23 in a clockwise direction.
  • La figure 5 montre un ressort d'équilibrage 2D pour une charnière droite dont la partie hélicoïdale 21 est enroulée dans le sens contraire de celui du ressort gauche 2G. Son extrémité extérieure comprend également un repli axial 22 pour insertion dans le trou 140 de la saillie 14 d'un flasque 1 et son extrémité intérieure comprend un repli radial 23 permettant de le tendre après l'assemblage.FIG. 5 shows a 2D balancing spring for a right hinge whose helical part 21 is wound in the opposite direction to that of the left spring 2G. Its outer end also comprises an axial fold 22 for insertion into the hole 140 of the projection 14 of a flange 1 and its inner end comprises a radial fold 23 allowing it to be tensioned after assembly.

Sur les figures 4 et 5, les replis radiaux 23 et axiaux 22 du ressort 20 ou 21 se trouvent sur les mêmes côtés de celui-ci, de telle sorte qu'il comprend un nombre entier de spires.In FIGS. 4 and 5, the radial 23 and axial 22 folds of the spring 20 or 21 are located on the same sides of the latter, so that it comprises a whole number of turns.

Les figures 6 et 7 sont respectivement une vue latérale de l'extérieur et une coupe en élévation (selon CC) vue de l'arrière, de la partie fixe d'une charnière gauche selon l'invention.Figures 6 and 7 are respectively a side view of the exterior and a section in elevation (according to CC) seen from the rear, of the fixed part of a left hinge according to the invention.

La partie fixe 3G de la charnière des figures 6 et 7 comprend une patte rectangulaire allongée 30, munie de deux rebords 301, 302 normaux tournés vers l'extérieur, les pattes 30 étant tenues dans le socle par simple insertion de façon à permettre un démontage et un remontage rapide du capot par l'utilisateur. La profondeur de l'insertion de la patte 30 dans ce socle (non représenté) est limitée par une butée 305 qui constitue la fond d'une nervure en saillie 306 sensiblement en forme de "U". Le haut de la patte 30 est solidaire d'une tête 31 en forme de coupelle qui comprend une paroi extérieure cylindrique 32 obturée vers l'intérieur d'un fond plat 33 en forme de rondelle ou anneau, portant en son centre une cavité cylindrique 34 prolongée d'un palier creux 35 dont l'extrémité libre affleure le plan défini par le bord de la paroi 32. La transition entre le palier cylindrique 35 et la cavité 34 dont le diamètre est notablement supérieur, est constituée par une surface radiale 36 qui, lors de l'assemblage de la tête 31 avec le flasque 1 permet l'engagement de la tête élargie 17-18 de sa saillie centrale 12 par encliquetage (voir plus loin et figure 11).The fixed part 3G of the hinge of FIGS. 6 and 7 comprises an elongated rectangular tab 30, provided with two normal flanges 301, 302 facing outwards, the tabs 30 being held in the base by simple insertion so as to allow disassembly and rapid reassembly of the cover by the user. The depth of the insertion of the tab 30 into this base (not shown) is limited by a stop 305 which constitutes the bottom of a projecting rib 306 substantially in the shape of a "U". The top of the tab 30 is integral with a cup-shaped head 31 which comprises a cylindrical outer wall 32 closed inwardly of a flat bottom 33 in the form of a washer or ring, carrying in its center a cylindrical cavity 34 extended by a hollow bearing 35, the free end of which is flush with the plane defined by the edge of the wall 32. The transition between the cylindrical bearing 35 and the cavity 34, the diameter of which is considerably greater, consists of a radial surface 36 which , during assembly of the head 31 with the flange 1 allows the engagement of the enlarged head 17-18 of its central projection 12 by snap-fastening (see below and Figure 11).

Plus précisément, lors de l'insertion du bout arrondi 18 de la tête élargie dans l'extrémité libre du trou constitué par le palier 35, les deux parties de saillie centrale 15 séparées par la fente 19 se rapprochent l'une de l'autre et pénetrent à l'intérieur du palier 35 sous l'effet d'une poussée exercée sur la face plate 10 du flasque 1, jusqu'à ce que l'élargissement 17 arrive au niveau du fond radial 36 de la cavité 34. A cet instant les deux parties séparées par la fente 19 s'éloignent l'une de l'autre et la face radiale 17 de la tête élargie prend appui sur celle du fond radial 36 de la cavité 34. Dès lors, la tête 31 de la partie fixe est réunie de façon tournante avec le flasque 1More specifically, during the insertion of the rounded end 18 of the enlarged head into the free end of the hole formed by the bearing 35, the two central protrusion parts 15 separated by the slot 19 approach each other and penetrate inside the bearing 35 under the effect of a thrust exerted on the flat face 10 of the flange 1, until the widening 17 arrives at the level of the radial bottom 36 of the cavity 34. At this instant the two parts separated by the slot 19 move away from each other and the radial face 17 of the enlarged head rests on that of the radial bottom 36 of the cavity 34. Therefore, the head 31 of the part fixed is rotatably joined with the flange 1

La face extérieure commune 38 de la cavité 34 et du palier 35 qui est cylindrique, est entourée d'une jupe cylindrique 39 sensiblement de même hauteur, dont une extrémité est solidaire du fond plat 33 de la tête 31. Cette jupe 39 est pourvue d'une découpe 40 en forme de créneau sur un peu plus d'un quart de sa circonférence. L'un 41 des bords de la découpe est situé sensiblement dans le prolongement de l'axe longitudinal de la patte 30, tandisque l'autre bord 42 est situé légèrement au-dessus d'un plan normal à cet axe et passant par l'axe commun de la cavité 34 et du palier 35. La profondeur de la découpe en créneau 40 est légèrement supérieur à la différence entre la hauteur de la troisième saillie 14 et de l'épaisseur de la paroi latérale du capot, de telle sorte que les bords 41 et 42 puissent jouer le rôle de butées en entrant en contact avec cette saillie 14. L'espace ménagé entre la face extérieure de la jupe 39 et la face intérieure de la paroi latérale 32 de la coupelle ou tête 31, est destiné à recevoir un ressort hélicoïdal d'équilibrage (2G, Figure 4, ou 2D, Figure 5).The common external face 38 of the cavity 34 and of the bearing 35 which is cylindrical, is surrounded by a cylindrical skirt 39 substantially of the same height, one end of which is integral with the flat bottom 33 of the head 31. This skirt 39 is provided with 'A cutout 40 in the form of a niche on a little more than a quarter of its circumference. One 41 of the edges of the cutout is located substantially in the extension of the longitudinal axis of the tab 30, while the other edge 42 is located slightly above a plane normal to this axis and passing through the common axis of the cavity 34 and of the bearing 35. The depth of the slot cutout 40 is slightly greater than the difference between the height of the third projection 14 and the thickness of the side wall of the cover, so that the edges 41 and 42 can act as stops by coming into contact with this projection 14. The space provided between the outer face of the skirt 39 and the inner face of the side wall 32 of the cup or head 31, is intended to receive a balancing coil spring (2G, Figure 4, or 2D, Figure 5).

La jonction entre la paroi latérale 32 et le fond plat 33 de la coupelle 31 est interrompue sur une partie de sa circonférence comprise entre un tiers et la moitié de celle-ci, par une fente 43 circonférentielle qui permet de tendre le ressort 20 ou 21 (figures 4 ou 5) par son bout radial 23 dont l'extrémité émerge de la tête 31. Cette fente 43 a été représentée de façon plus claire et détaillée sur les vues en coupe, partiellement en arraché, des figures 8 et 9. A cause de la présence de cette fente 43 séparant le fond 33 de la paroi latérale 32, celle-ci est également réunie à la jupe 40 à l'aide de trois nervures 44 radiales de renforcement, sur la partie non occupée par cette fente 43.The junction between the side wall 32 and the flat bottom 33 of the cup 31 is interrupted over a part of its circumference between one third and half of it, by a circumferential slot 43 which makes it possible to tension the spring 20 or 21 (Figures 4 or 5) by its radial end 23 whose end emerges from the head 31. This slot 43 has been shown in a more clear and detailed manner in the sectional views, partially broken away, of Figures 8 and 9. A because of the presence of this slot 43 separating the bottom 33 of the side wall 32, the latter is also joined to the skirt 40 by means of three radial reinforcing ribs 44, on the part not occupied by this slot 43.

Les figures 8 et 9 sont des vues en coupe et en arrachée selon DD des parties fixes respectives des charnières gauche 3G et droite 3D, permettant d'illustrer la forme de fentes 43G et 43D.Figures 8 and 9 are sectional and cutaway views along DD of the respective fixed parts of the left hinges 3G and right 3D, to illustrate the form of slots 43G and 43D.

L'extrémité des fentes 43G et 43D qui est orientée vers l'arrière du boîtier ou bâti (non représenté) devant être recouvert du capot pivotant, est muni d'un prolongement axial ou parallèle à la génératrice 45 qui est situé au voisinage de la jonction du bord arrière de la patte 30 avec la paroi 32 de la coupelle et qui est destiné à loger le repli radial (23) du ressort (20 ou 21), lors de l'assemblage. L'autre extrémité de la fente 43 qui est tournée vers l'avant, est munie d'un prolongement en équerre composé d'une partie radiale 46 et d'une courte partie circonférentielle 47 qui est parallèle à la fente 43 elle-même, de façon à former une sorte de "L" inversé. Lorsque le ressort (20 ou 21) a été tendu, l'extrémité de son repli radial 23 est retenu par le fond de la partie circonférentielle 47 sur lequel il s'appuie alors. La hauteur des nervures de renforcement radiales 44 est choisie sensiblement égale à celle du bord intérieur de la partie circonférentielle 47 logeant le repli radial du ressort (20 ou 21) dont la spire intérieure y prend appui.The end of the slots 43G and 43D which is oriented towards the rear of the housing or frame (not shown) to be covered with the pivoting cover, is provided with an axial extension or parallel to the generator 45 which is located in the vicinity of the junction of the rear edge of the tab 30 with the wall 32 of the cup and which is intended to accommodate the radial fold (23) of the spring (20 or 21), during assembly. The other end of the slot 43 which faces forward, is provided with an angled extension composed of a radial part 46 and a short circumferential part 47 which is parallel to the slot 43 itself, so as to form a sort of inverted "L". When the spring (20 or 21) has been tensioned, the end of its radial fold 23 is retained by the bottom of the circumferential part 47 on which it then rests. The height of the radial reinforcing ribs 44 is chosen to be substantially equal to that of the inner edge of the circumferential part 47 housing the radial fold of the spring (20 or 21) whose inner turn is supported there.

La figure 10 montre une coupe partielle en élévation de la charnière assemblée avec la paroi latérale du capot en position horizontale (fermée) et la figure 11 montre une coupe selon ÊÊ de la figure 10 (qui elle est une coupe selon FF de la figure 11).Figure 10 shows a partial section in elevation of the hinge assembled with the side wall of the cover in horizontal position (closed) and Figure 11 shows a section along ÊÊ of Figure 10 (which is a section along FF of Figure 11 ).

Sur la figure 10, le flasque 1 n'a pas été coupé et on n'y voit que sa partie plate en forme de disque avec sa saillie centrale 12 dont la première partie cylindrique 15 traverse un trou 51 dans la paroi latérale 50 du capot 5 et dont la seconde partie cylindrique 16 constitue l'axe de pivotement pouvant tourner dans le palier 35 de la partie fixe ou tête 31. On y voit également que la tête ou le bout élargi 17-18 de la partie centrale 16 assure l'assemblage du flasque 1 avec la tête 31 de la partie fixe, par son engagement avec le fond plat (radial) de la cavité centrale 34.In FIG. 10, the flange 1 has not been cut and one sees there only its flat disc-shaped part with its central projection 12, the first cylindrical part 15 of which passes through a hole 51 in the side wall 50 of the cover. 5 and whose second cylindrical part 16 constitutes the pivot axis which can rotate in the bearing 35 of the fixed part or head 31. It can also be seen there that the head or the enlarged end 17-18 of the central part 16 ensures the assembly of the flange 1 with the head 31 of the fixed part, by its engagement with the flat (radial) bottom of the central cavity 34.

Sur la figure 11, on peut voir que les deux pions ou tétons 13 et 14 diamétralement opposés du flasque 1 s'engagent respectivement dans des trous 52 et 53 traversant la paroi latérale 50 du capot 5, de façon à assurer l'ancrage de celui-ci par rapport à celui-là. On peut y voir également l'insertion du repli axial 22 du ressort 20 dans le trou 141 du troisième téton 14, ainsi que celle de son repli radial dans la partie circonférentielle retournée 47 de l'autre extrémité de la fente 43G.In FIG. 11, it can be seen that the two diametrically opposite pins or studs 13 and 14 of the flange 1 engage respectively in holes 52 and 53 crossing the side wall 50 of the cover 5, so as to anchor that this compared to that one. We can also see the insertion of the axial fold 22 of the spring 20 in the hole 141 of the third stud 14, as well as that of its radial fold in the inverted circumferential part 47 of the other end of the slot 43G.

Des trois parties constitutives de la charnière latérale équilibrée par ressort de torsion, seul ce dernier est métallique, c'est-à-dire en acier. Les deux autres parties, c'est-à-dire le flasque 1 et la partie fixe 3 comprenant la patte 30 et la tête 31, sont respectivement obtenus par moulage, par exemple, en un matériau plastique chargé de fibres de verre, tel que le polyamide (6-6) avec une charge de 20 pour cent de fibres de verre, qui assure une rigidité mécanique et une élasticité suffisante pour l'encliquetage des pièces et le support d'un capot ou couvercle relativement lourd en une résine acrylique transparente, par exemple. Une charnière réalisée conformément à l'invention comprend un minimum de composants (trois), est facile à réaliser, ainsi qu'à assembler. Par conséquent, elle constitue une économie non négligeable par rapport à celles de l'état de la technique. Un autre avantage est constitué par le fait que lors du montage de la charnière, le ressort n'est pas tendu et ne nécessite pas un outillage compliqué pour réunir la partie fixe à la partie tournante.Of the three constituent parts of the lateral hinge balanced by torsion spring, only the latter is metallic, that is to say steel. The other two parts, that is to say the flange 1 and the fixed part 3 comprising the tab 30 and the head 31, are respected. obtained by molding, for example, from a plastic material loaded with glass fibers, such as polyamide (6-6) with a load of 20 percent glass fibers, which provides mechanical rigidity and sufficient elasticity for the 'snap of the parts and the support of a hood or relatively heavy cover in a transparent acrylic resin, for example. A hinge produced in accordance with the invention comprises a minimum of components (three), is easy to produce, as well as to assemble. Consequently, it constitutes a significant saving compared to those of the state of the art. Another advantage is constituted by the fact that during assembly of the hinge, the spring is not tensioned and does not require complicated tools to join the fixed part to the rotating part.
