A stop (58) is fixed on the said upright of the frame (1) below the point of connection between the spring (55) and the rod (53). The spring (55) presses the rod (53) against the stop (58). The materials of the rod (53) and of the stop (58) are such that the stop (58) acts like a brake. The point of attachment (56) of the spring (55) to the upright of the frame (1) is sufficiently high to draw the link rod (49) back against the rabbet of the upright of the first wing (2). Another version of the elastic means is described, as are exemplary embodiments of hinges. <IMAGE>

La lucarne des Figs. 1 et 2 se compose d'un cadre fixe 1, d'un premier battant à rabattement 2 et d'un second battant 3 portant le vitrage.The dormer window in Figs. 1 and 2 consists of a fixed frame 1, a first folding leaf 2 and a second leaf 3 carrying the glazing.

A la Fig. 1, on suppose le battant 3 verrouillé par rapport au battant 2 et ce dernier libre par rapport au cadre 1. Dans ces conditions, un système de moyens élastiques 48 maintient le battant 2 ouvert.In Fig. 1, the leaf 3 is assumed to be locked relative to the leaf 2 and the latter free relative to the frame 1. Under these conditions, a system of elastic means 48 keeps the leaf 2 open.

Le système 48 comprend une biellette 49 pouvant, à une de ses extrémités, pivoter autour d'un axe 50 fixé sur la face externe du montant 51 du battant 2. L'autre extrémité 52 de la biellette 49 est appuyée sur le bord de la feuillure du montant 51. Sur l'extrémité 52 est monté un axe autour duquel peut pivoter l'extrémité d'une tige 53, relativement longue. En un point intermédiaire 54 de la tige 53, est fixée l'extrémité d'un ressort de traction 55 dont l'autre extrémité est fixée, en 56, sur la face interne du montant 57 du cadre 1. Sur la face interne du montant 57, entre la tige 53 et le point 54, au-dessous du ressort 55, est fixée une butée 58 contre laquelle le ressort 55 applique la partie inférieure de la tige 53.The system 48 comprises a link 49 which can, at one of its ends, pivot around an axis 50 fixed on the external face of the upright 51 of the leaf 2. The other end 52 of the link 49 is supported on the edge of the rebate of the upright 51. On the end 52 is mounted an axis around which the end of a relatively long rod 53 can pivot. At an intermediate point 54 of the rod 53, the end of a tension spring 55 is fixed, the other end of which is fixed, at 56, to the internal face of the upright 57 of the frame 1. On the internal face of the upright 57, between the rod 53 and the point 54, below the spring 55, a stop 58 is fixed against which the spring 55 applies the lower part of the rod 53.

Dans la position de la Fig. 1, le poids du battant 2 est transmis par la feuillure de 51 à la biellette 49, puis par la tige 53 à la butée 58. Le coefficient de frottement entre les matériaux de la tige 53 et de la butée 58, ainsi que la forme de la surface de contact entre les deux pièces, sont choisis de manière à agir comme un frein en toute position.In the position of FIG. 1, the weight of leaf 2 is transmitted by the rebate of 51 to the rod 49, then by the rod 53 to the stop 58. The coefficient of friction between the materials of the rod 53 and of the stop 58, as well as the shape of the contact surface between the two parts, are chosen so as to act as a brake in any position.

Les montants 51 et/ou 57 comportent, dans toute la zone où la tige 53 et la biellette 49 se déplacent, des diminutions d'épaisseur pour laisser le jeu nécessaire aux mouvements de 53 et 49.The uprights 51 and / or 57 comprise, throughout the zone where the rod 53 and the link 49 move, thickness reductions to leave the clearance necessary for the movements of 53 and 49.

Comme le montre encore la Fig. 1, sous le bord de la feuillure du montant 57, est -fixé un plat ou une cornière métallique 60, formant feuillure, qui définit par sa face horizontale tournée vers l'intérieur une surface d'appui pour l'épaulement 61 du montant 62 du battant 3, comme on va le voir en relation avec la Fig. 2. La longueur du plat ou de la cornière 60 peut être limitée.As still shown in FIG. 1, under the edge of the rebate of the upright 57, is fixed a flat or a metal angle 60, forming rebate, which defines by its horizontal face facing inward a bearing surface for the shoulder 61 of the upright 62 of leaf 3, as will be seen in relation to FIG. 2. The length of the plate or the angle 60 can be limited.

A la Fig. 2, on suppose que le battant 2 est libre par rapport au cadre 1 et que le battant 3 est libre par rapport au battant 2. Dès que le battant 3 est déverrouillé, il pivote vers le bas jusqu'à ce que l'épaulement 61 repose sur la face supérieure de la cornière 60. En appuyant sur le battant 3, on fait glisser l'épaulement jusqu'à, par exemple atteindre la position représentée à la Fig. 2. Le battant 2 a alors pivoté vers le haut, entrainé par 2, si bien que l'extrémité 52 de la biellette ne repose plus sur le bord de la feuillure du montant 51. En effet, l'extrémité libre 108 de la tige 53 se termine en forme de crochet qui s'accroche derrière la butée 58. La longueur de la biellette 49, plus celle de la tige 53, définissent la position limite que l'on désire pour le pivotement du battant 2.In Fig. 2, it is assumed that the wing 2 is free with respect to the frame 1 and that the wing 3 is free with respect to the wing 2. As soon as the wing 3 is unlocked, it pivots down until the shoulder 61 rests on the upper face of the angle iron 60. By pressing on the wing 3, the shoulder is slid until, for example, reaching the position shown in FIG. 2. The leaf 2 then pivoted upwards, driven by 2, so that the end 52 of the link no longer rests on the edge of the rebate of the upright 51. In fact, the free end 108 of the rod 53 ends in the form of a hook which hooks behind the stop 58. The length of the link 49, plus that of the rod 53, defines the limit position that is desired for the pivoting of the leaf 2.

A la Fig. 3, on a représenté un système de charnière 63, avec un dessin en traits plein définissant la position ouverte du système, un dessin en traits mixtes une position intermédiaire, et un dessin en traits tirets la position fermée. Le système 63 se compose de deux plaques 64 et 65 qui sont réunies par deux biellettes courtes 66 et 67. La plaque 64 est supposée appliquée sur le montant du cadre fixe tandis que la plaque 65 est appliquée sur le montant du cadre mobile, fixe et mobile étant compris dans leur sens relatif. Une extrémité de la biellette 66 peut tourner autour d'un axe 68 solidaire de la plaque 64 tandis que son autre extrémité peut tourner autour d'un axe 69 solidaire de la plaque 65. Un extrémité de la biellette 67 peut tourner autour d'un axe 70 solidaire de la plaque 64 tandis que son autre extrémité peut tourner autour d'un axe 71 solidaire de la plaque 65. Les axes 68 et 70 sont évidemment fixes, comme la plaque 64 qui est solidaire du montant 57 du cadre fixe 1. Donc les axes 68 forment les sommets d'un quadrilatère déformable ayant un côté fixe 68-70 et deux côtés, concrétisés par 66 et 67, qui ont des longueurs fixes.In Fig. 3, there is shown a hinge system 63, with a solid line drawing defining the open position of the system, a dashed line drawing an intermediate position, and a dashed line drawing the closed position. The system 63 consists of two plates 64 and 65 which are joined by two short links 66 and 67. The plate 64 is assumed to be applied to the amount of the fixed frame while the plate 65 is applied to the amount of the movable, fixed and mobile being understood in their relative sense. One end of the rod 66 can rotate around an axis 68 integral with the plate 64 while its other end can rotate around an axis 69 integral with the plate 65. One end of the rod 67 can rotate around a axis 70 secured to the plate 64 while its other end can rotate around an axis 71 secured to the plate 65. The axes 68 and 70 are obviously fixed, like the plate 64 which is secured to the upright 57 of the fixed frame 1. So the axes 68 form the vertices of a deformable quadrilateral having a fixed side 68-70 and two sides, embodied by 66 and 67, which have fixed lengths.

Dans un exemple préféré de réalisation du système de charnière 63, les distances approximatives entre axes sont de 35 mm entre 68 et 70, de 29 mm entre 70 et 71, de 24 mm entre 68 et 69, et de 16 mm entre 69 et 71. Si l'on modifie la taille du système de charnière, on conserve les différents rapports entre ces distances.In a preferred embodiment of the hinge system 63, the approximate distances between axes are 35 mm between 68 and 70, 29 mm between 70 and 71, 24 mm between 68 and 69, and 16 mm between 69 and 71 If you change the size of the hinge system, you keeps the different relationships between these distances.

Il est important de noter qu'avec le système de charnière 63, le centre instantané de rotation de la plaque 65 se trouve, au début de l'ouverture, nettement au-dessus du bord supérieur de la plaque 64 qui est fixée sur le montant fixe du cadre fixe, puis descend approximativement jusqu'au niveau du bord supérieur de la plaque 64, en fin d'ouverture à 90°. Donc, on obtient ;un désengagement du cadre mobile par rapport au cadre fixe qui permet de ne placer des tôles de revêtement contre la pluie que sur la traverse supérieure du cadre fixe. Toutefois, ici l'angle d'ouverture est plus grand et, également, le système peut être placé non en bout de montant, mais dans la zone médiane et donc être directement utilisable sur des châssis à battant unique pivotant par le milieu.It is important to note that with the hinge system 63, the instantaneous center of rotation of the plate 65 is, at the start of the opening, clearly above the upper edge of the plate 64 which is fixed to the upright. fixed of the fixed frame, then descends approximately to the level of the upper edge of the plate 64, at the end of 90 ° opening. So, we obtain; a disengagement of the movable frame relative to the fixed frame which allows to place sheets of coating against rain only on the upper crossmember of the fixed frame. However, here the opening angle is greater and, also, the system can be placed not at the end of the upright, but in the middle zone and therefore be directly usable on single casement frames pivoting through the middle.

A la Fig. 4, on a représenté un autre système de charnière 72 en position fermée. Le système 72 se compose de deux plaques 73 et 74, la première sur la partie fixe et l'autre sur la partie mobile, qui sont réunies par deux biellettes 75 et 76. Une extrémité de la biellette 75 peut tourner autour d'un axe 77 solidaire de la plaque 73 tandis que son autre extrémité porte un axe 78 sur lequel est articulée une autre biellette 79. Une extrémité de la biellette 76 peut tourner autour d'un axe 80 solidaire de la plaque 74 tandis que sa partie intermédiaire peut tourner autour d'un axe 81 solidaire de la partie médiane de la biellettte 75' et que son autre extrémité porte un ergot 82 qui coulisse dans une fente 83 de la plaque 73. Enfin, l'autre extrémité de la biellette 79 peut tourner autour d'un axe 84' solidaire de la plaque 74. Dans un exemple préféré de réalisation du système de charnière 7à, les dimensions approximatives sont les suivantes: entre 77 et 78, 21 mm; entre 77 et 81, 11 mm; entre 81 et 78, 18 mm; entre 78 et 84, 19 mm; entre 80 et 84, 14 mm; entre 80 et 81, 16 mm; entre 81 et 82, 32 mm; et entre 80 et 82, 38 mm. Il apparaît donc que, sur la biellette 75, les points 77, 81 et 78 ne sont pas alignés, mais forment un triangle très applati, dont l'angle obtus en 81 est ouvert vers la plaque 74. De même, les points 80, 81 et 82 ne sont pas alignés, mais forment un triangle aplati, dont l'angle obtus en 81 est ouvert vers la plaque 73. La lumière 83 est dirigée obliquement vers le bas en se dirigeant de la plaque 73 vers la plaque 74. En position fermée, Fig. 4, l'ergot 82 se trouve en haut de la lumière 83 et la droite joignant 81 et 82 est pratiquement parallèle à la direction du montant du cadre fixe. En position ouverte, Fig. 5, l'ergot 82 se trouve en bas de la lumière 83 et la plaque 74 a tourné de plus de 90° par rapport à la plaque 73. Elle peut pivoter de pratiquement 180°.In Fig. 4, there is shown another hinge system 72 in the closed position. The system 72 consists of two plates 73 and 74, the first on the fixed part and the other on the mobile part, which are joined by two links 75 and 76. One end of the link 75 can rotate around an axis 77 secured to the plate 73 while its other end carries an axis 78 on which another link 79 is articulated. One end of the link 76 can rotate around an axis 80 secured to the plate 74 while its intermediate part can rotate around an axis 81 integral with the middle part of the link 75 'and that its other end carries a lug 82 which slides in a slot 83 of the plate 73. Finally, the other end of the link 79 can rotate around 'an axis 84' integral with the plate 74. In a preferred embodiment of the hinge system 7a, the approximate dimensions are as follows: between 77 and 78, 21 mm; between 77 and 81, 11 mm; between 81 and 78, 18 mm; between 78 and 84, 19 mm; between 80 and 84, 14 mm; between 80 and 81, 16 mm; between 81 and 82, 32 mm; and between 80 and 82, 38 mm. It therefore appears that, on the link 75, the points 77, 81 and 78 are not aligned, but form a very flat triangle, the obtuse angle of 81 is open towards the plate 74. Similarly, the points 80, 81 and 82 are not aligned, but form a flattened triangle, the obtuse angle at 81 is open towards the plate 73. The lumen 83 is directed obliquely downward from the plate 73 towards the plate 74. In closed position, Fig. 4, lug 82 is in top of the light 83 and the right joining 81 and 82 is practically parallel to the direction of the amount of the fixed frame. In the open position, Fig. 5, the lug 82 is located at the bottom of the lumen 83 and the plate 74 has rotated more than 90 ° relative to the plate 73. It can pivot almost 180 °.

Avec le système de charnière 72, on-obtient encore un désengagement longitunal du cadre mobile par rapport au cadre fixe, au début de l'ouverture. Par rapport au système 63, le système 72 permet d'obtenir des angles d'ouverture plus grand.With the hinge system 72, one still obtains a longitudinal disengagement of the movable frame relative to the fixed frame, at the start of the opening. Compared to system 63, system 72 makes it possible to obtain larger opening angles.

Aux Figs. 6 et 7, on a représenté deux positions différentes d'un système de charnière à pignons 85, qui constitue une autre variante. Le système 85 se compose de deux arbres 86 et 87 qui sont parallèles entre eux et à l'axe de rotation du système. Les deux arbres 86 et 87 sont reliés entre eux par des pièces 88 servant d'entretoises. Chaque arbre comporte un pignon axial. Le pignon 89 de l'arbre 86 est fixe par rapport à 86 et le pignon 90 de l'arbre 87 est fixé par rapport à 87. Les pignons 89 et 90 s'engrènent. Le pignon 89, avec l'arbre 86, est solidaire du cadre fixe. Le pignon 90 est solidaire du cadre mobile. En pratique, le pignon 89 est relié au montant correspondant du cadre fixe par une plaque 91 tandis que le pignon 90 est relié au montant correspondant du cadre mobile par une plaque 92. Les diamètres des deux pignons étant supposés égaux, on peut voir qu'entre la position fermée de la Fig. 6 et la position extrême ouverte de la Fig. 7, la plaque 92 a pratiquement tourné de 180°.In Figs. 6 and 7, there are shown two different positions of a pinion hinge system 85, which constitutes another variant. The system 85 consists of two shafts 86 and 87 which are parallel to each other and to the axis of rotation of the system. The two shafts 86 and 87 are interconnected by parts 88 serving as spacers. Each shaft has an axial pinion. The pinion 89 of the shaft 86 is fixed relative to 86 and the pinion 90 of the shaft 87 is fixed relative to 87. The pinions 89 and 90 mesh. The pinion 89, with the shaft 86, is integral with the fixed frame. The pinion 90 is integral with the movable frame. In practice, the pinion 89 is connected to the corresponding amount of the fixed frame by a plate 91 while the pinion 90 is connected to the corresponding amount of the movable frame by a plate 92. The diameters of the two pinions being assumed to be equal, it can be seen that between the closed position of Fig. 6 and the extreme open position of FIG. 7, the plate 92 has practically rotated 180 °.

Les Figs. 8 et 9, où les arbres 86 et 87 sont respectivement associés au montants fixe 93 -et mobile 94, illustrent comment le cadre mobile pivote par rapport au cadre fixe.Figs. 8 and 9, where the shafts 86 and 87 are respectively associated with the fixed upright 93 and mobile 94, illustrate how the mobile frame pivots relative to the fixed frame.

Aux Fig. 10 à 12., on a représenté, en trois positions différentes, une variante 95 du système de charnière à pignons 85 des Figs. 6 et 7. Le système 95 se compose de deux arbres 96 et 97 qui sont parallèles entre eux et à l'axe de rotation du système. L'arbre 96 porte un pignon axial 98 qui peut tourner librement par rapport à lui, mais qui est solidaire de la biellette. L'arbre 97 porte un pignon 99 dont il est solidaire. L'arbre 97 peut tourner dans des paliers qui sont reliés au pignon 98 par des pièces 100 servant d'entretoises. Les pignons 98 et 99 s'engrènent. L'arbre 96 est solidaire du montant 101 du dormant d'une fenêtre à ouvrants à la française tandis que l'arbre 97 est solidaire du montant 102 du battant de cette fenêtre.In Figs. 10 to 12., there is shown, in three different positions, a variant 95 of the pinion hinge system 85 of FIGS. 6 and 7. The system 95 consists of two shafts 96 and 97 which are parallel to each other and to the axis of rotation of the system. The shaft 96 carries an axial pinion 98 which can rotate freely with respect to it, but which is integral with the link. The shaft 97 carries a pinion 99 of which it is integral. The shaft 97 can rotate in bearings which are connected to the pinion 98 by parts 100 serving as spacers. Sprockets 98 and 99 mesh. The tree 96 is secured to the amount 101 of the frame of a window with French sashes while the shaft 97 is secured to the amount 102 of the window sash.

La fig. 10 montre le système 95 en position de fenêtre fermée, la Fig. 11 le montre en position de fenêtre entrouverte et la Fig. 12 en position ouverte. Il apparaît qu'en partant de la position fermée de la Fig. 10, quand on fait tourner le battant 102 dans le sens contraire des aiguilles d'une montre, l'axe 97 tourne par rapport à l'axe 96 dans le sens des aiguilles d'une montre. En effet, la rotation du pignon 99, dans le sens inverse, fait tourner le pignon 98, libre par rapport à 96, dans le sens direct et la rotation de 98 entraîne celle l'entretoise 100 dans le sens direct.Fig. 10 shows the system 95 in the closed window position, FIG. 11 shows it in the half-open window position and FIG. 12 in the open position. It appears that starting from the closed position of FIG. 10, when the leaf 102 is rotated anti-clockwise, the axis 97 rotates with respect to the axis 96 in the clockwise direction. In fact, the rotation of the pinion 99, in the opposite direction, causes the pinion 98, free relative to 96, to rotate in the direct direction and the rotation of 98 causes that of the spacer 100 in the direct direction.

On peut constater que, quand le pignon 99 a tourné d'un angle A sur lui-même, l'axe 97 a tourné d'un angle - A/2 par rapport à 96. Il en résulte que le battant 102 se déplace, au second ordre près, parallèlement au dormant 101 quand il quitte la position de fermeture de la Fig. 10. Cela est important car on peut monter sur le dormant 101 un joint 103 perpendiculaire au montant 101. En position de fermeture, le joint 103 trouve sa place dans une rainure 104 creusée dans le montant 102 du battant. Par ailleurs, le montant 102 se place dans une feuillure prévue dans le montant 101 de manière que la face externe de 102 soit dans le même plan que celle de 101. L'intervalle 105 entre le bord externe 106 de 102 et le flanc de la feuillure de 101 peut être de l'ordre de 1 mm. L'air extérieur en surpression, par exemple à cause du vent, vient alors à travers 105, appliquer le joint 103 latéralement contre le flanc interne 107 de la rainure 104. Il en résulte que le joint 103 travaille dans d'excellentes conditions et, notamment, ne s'écrase pas dans le sens longitudinal.We can see that, when the pinion 99 has rotated by an angle A on itself, the axis 97 has rotated by an angle - A / 2 with respect to 96. As a result, the leaf 102 moves, to the second order, parallel to the frame 101 when it leaves the closed position of FIG. 10. This is important because it is possible to mount on the frame 101 a seal 103 perpendicular to the upright 101. In the closed position, the seal 103 finds its place in a groove 104 hollowed out in the upright 102 of the leaf. Furthermore, the amount 102 is placed in a rebate provided in the amount 101 so that the outer face of 102 is in the same plane as that of 101. The interval 105 between the outer edge 106 of 102 and the side of the rebate of 101 can be of the order of 1 mm. The outside air under overpressure, for example due to the wind, then comes through 105, applying the seal 103 laterally against the internal flank 107 of the groove 104. As a result, the seal 103 works in excellent conditions and, in particular, does not crash in the longitudinal direction.

A la Fig. 13, on a représenté une variante des moyens élastiques décrits en relation avec les Fig. 1 et 2. On y retrouve la biellette 49 dont une extrémité pivote autour de l'axe 50, mais sur son autre extrémité 52 est montée pivotante, non plus la tige 53, mais une autre biellette 109 dont l'autre extrémité est reliée, par un axe 110, à un coulisseau 111. Le coulisseau 111 a la forme d'un petit bloc qui se loge et coulisse dans une coulisse 112, formée par une cornière en U. La cornière 112 est fixée sur la face interne du montant 57, non montré, et est ouverte vers le haut. Dans le bloc du coulisseau 111 est prévu un trou taraudé dans lequel est vissée une vis 113 qui porte, à son extrémité, un insert 114 qui se loge dans le bout de l'hélice d'un ressort 115. L'autre extrémité du ressort 115 est fixée à l'extrémité supérieure de la coulisse 112. Le ressort 115 est un ressort de traction qui est du même côté de la biellette 109 que la biellette 49. Les matériaux du coulisseau 111 et de la coulisse 112, et leurs dimensions respectives, sont tels que le coulisseau joue le rôle d'un frein dans la coulisse. Le ressort 115 facilite l'ouverture du battant, mais, étant donné le rôle de frein du coulisseau, il ne peut le faire bouger seul. Il en résulte que,' dès que l'on donne une position au battant par rapport au cadre, il la garde.In Fig. 13, a variant of the elastic means described in relation to FIGS. 1 and 2. There we find the link 49, one end of which pivots about the axis 50, but on its other end 52 is pivotally mounted, no longer the rod 53, but another link 109 whose other end is connected, by a pin 110, to a slide 111. The slide 111 has the shape of a small block which is housed and slides in a slide 112, formed by a U-shaped angle iron. The angle iron 112 is fixed on the internal face of the upright 57 , not shown, and is open up. In the block of slide 111 is provided with a tapped hole into which is screwed a screw 113 which carries, at its end, an insert 114 which is housed in the end of the propeller of a spring 115. The other end of the spring 115 is fixed to the upper end of the slide 112. The spring 115 is a tension spring which is on the same side of the link 109 as the link 49. The materials of the slide 111 and of the slide 112, and their respective dimensions, are such that the slide acts as a brake in the slide. The spring 115 makes it easier to open the leaf, but, given the role of the slide brake, it cannot move it alone. It follows that, 'as soon as a leaf is given a position relative to the frame, it keeps it.
