Description

La présente invention concerne les volets basculants d'obturation d'une ouverture tels que ceux que l'on rencontre notamment en imposte au-dessus d'une baie de voiture de transport en commun (autobus ou wagon).The present invention relates to tilting shutters for closing an opening such as those encountered in particular overhead over a bay of public transport car (bus or wagon).

Le document FR-A 2 442 946 illustre un volet de ce type, articulé par son bord inférieur au bord inférieur du châssis de l'ouverture qu'il obture. Un dispositif de rappel élastique coopère avec le volet pour le maintenir dans deux positions stables en appui sur des butées fixes, qui sont des positions extrêmes de fermeture ou d'ouverture maximum, et dans une position intermédiaire dans laquelle le volet n'est pas en appui sur des butées mais est maintenu élastiquement par le ressort. Dans cette position intermédiaire , le volet peut vibrer compte tenu de la nature élastique de l'un de ses appuis.Document FR-A 2 442 946 illustrates a shutter of this type, articulated by its lower edge to the lower edge of the frame of the opening which it closes. An elastic return device cooperates with the flap to keep it in two stable positions bearing on fixed stops, which are extreme positions of maximum closing or opening, and in an intermediate position in which the flap is not in support on stops but is held elastically by the spring. In this intermediate position, the flap can vibrate given the elastic nature of one of its supports.

La présente invention entend apporter un perfectionnement à ce type de dispositifs en donnant au volet un appui ferme dans sa troisième position intermédiaire.The present invention intends to provide an improvement to this type of device by giving the shutter a firm support in its third intermediate position.

A cet effet, l'invention a pour objet un dispositif d'articulation et de maintien dans trois positions stables d'un volet d'obturation basculant d'une ouverture dont l'un des bords est équipé d'une traverse mobile engagée dans la gouttière d'une traverse d'articulation fixe appartenant au châssis de l'ouverture, dans lequel la traverse mobile est maintenue en appui contre une aile de cette gouttière le long d'au moins une surface longitudinale d'articulation par un organe élastique disposé à l'intérieur de la gouttière entre la traverse mobile et l'autre bord de la gouttière . Selon l'invention, l'organe élastique est d'orientation variable pour que, dans la première position du volet, son effet soit dirigé au-dessus de la surface d'articulation susdite et dans la seconde position du volet son effet soit dirigé au-dessous de cette surface, la traverse mobile comportant une paire de surfaces d'articulation sensiblement parallèles telles que la surface d'articulation susdite est constituée soit par la surface supérieure de ladite paire lorsque le volet est dans sa première position, soit par la surface inférieure de ladite paire lorsque le volet est dans sa seconde position, l'autre surface étant alors éloignée de l'aile susdite, les deux surfaces étant simultanément au contact de l'aile dans la troisième position intermédiaire du volet, l'effet de l'organe élastique étant alors dirigé entre les deux surfaces.To this end, the subject of the invention is a hinge and holding device in three stable positions for a tilting shutter of an opening of which one of the edges is equipped with a movable cross member engaged in the gutter of a fixed articulation cross member belonging to the frame of the opening, in which the movable cross member is held in abutment against a wing of this gutter along at least one longitudinal articulation surface by an elastic member disposed at the interior of the gutter between the movable cross member and the other edge of the gutter. According to the invention, the elastic member is of variable orientation so that, in the first position of the flap, its effect is directed above the aforementioned articulation surface and in the second position of the flap its effect is directed to the below this surface, the movable cross member comprising a pair of substantially parallel articulation surfaces such that the aforementioned articulation surface is formed either by the upper surface of said pair when the flap is in its first position, or by the surface lower of said pair when the flap is in its second position, the other surface then being distant from the aforementioned wing, the two surfaces being simultaneously in contact with the wing in the third intermediate position of the flap, the effect of the the elastic member then being directed between the two surfaces.

Dans un mode de réalisation préféré de l'invention, les surfaces susdites sont portées par des bourrelets cylindriques longitudinaux extérieurs en une seule pièce avec la traverse mobile, tandis que l'aile de la traverse fixe comporte des gorges de réception desdits bourrelets.In a preferred embodiment of the invention, the aforementioned surfaces are carried by external longitudinal cylindrical beads in one piece with the movable cross member, while the wing of the fixed cross member has grooves for receiving said beads.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif.The invention will be better understood during the description given below by way of purely indicative and nonlimiting example.

Il sera fait référence aux dessins annexés dans lesquels:

  • - la figure 1 est une vue en coupe du dispositif selon l'invention dans la position d'obturation du volet,
  • - la figure 2 est une même vue en coupe du dispositif, le volet étant dans sa position intermédiaire,
  • - la figure 3 illustre par une même vue le volet dans sa position d'ouverture maximale.
Reference will be made to the appended drawings in which:
  • FIG. 1 is a sectional view of the device according to the invention in the shutter closing position,
  • FIG. 2 is the same sectional view of the device, the flap being in its intermediate position,
  • - Figure 3 illustrates in a single view the flap in its maximum open position.

Sur ces figures, la référence 1 représente le châssis de l'ouverture 2 que l'on peut obturer ou découvrir par le volet 2. Ce châssis sera par exemple monté en imposte audessus d'une baie 4, généralement fixe, d'un véhicule de transport en commun (bus, voiture de chemin de fer...) . La traverse supérieure 1 a du châssis 1 est équipée d'un joint d'étanchéité 5 à lèvre contre lequel vient s'appliquer le volet 3 dans sa position de fermeture. La traverse inférieure 1 b du châssis est formée par un profilé en forme générale de gouttière qui possède une aile extérieure 6 sensiblement parallèle au plan de l'ouverture 2 et une aile intérieure 7 qui constitue un support pour une traverse secondaire 8 équipée à son extrémité libre d'un patin 8a en élastomère, dont le rôle sera explicité ci-après.In these figures, the reference 1 represents the chassis of the opening 2 which can be closed or uncovered by the flap 2. This chassis will for example be mounted in a transom above a bay 4, generally fixed, of a vehicle public transport (bus, railway car ...). The upper cross member 1a of the chassis 1 is fitted with a lip seal 5 against which the flap 3 is applied in its closed position. The lower cross member 1b of the chassis is formed by a profile in the general shape of a gutter which has an outer wing 6 substantially parallel to the plane of the opening 2 and an inner wing 7 which constitutes a support for a secondary cross member 8 equipped at its end. free of an elastomer pad 8a, the role of which will be explained below.

Le panneau 3 est équipé, le long de son bord inférieur, d'une traverse mobile 9 au moyen de laquelle il est attelé au châssis 1 sous la forme d'une pseudo articulation. La traverse 9 possède deux bourrelets longitudinaux 10 et 11 sur sa face avant, parallèles, dont les surfaces cylindriques 10a et 11 a peuvent coopérer et être reçues par deux rainures 12 et 13 ménagées en correspondance sur la face intérieure de l'aile 6 du profilé 1b. Le plan 14 qui contient les axes des bourrelets cylindriques forme un angle A avec le plan du volet 3.The panel 3 is equipped, along its lower edge, with a movable cross member 9 by means of which it is coupled to the chassis 1 in the form of a pseudo joint. The cross member 9 has two longitudinal beads 10 and 11 on its front face, parallel, the cylindrical surfaces 10a and 11a can cooperate and be received by two grooves 12 and 13 formed in correspondence on the inner face of the wing 6 of the profile 1b. The plane 14 which contains the axes of the cylindrical beads forms an angle A with the plane of the flap 3.

La traverse 9 possède, sur son autre côté, une rainure 15 dans laquelle vient se loger une branche 16a d'un ressort plan 16 en épingle ou en S dont l'autre branche 16b prend appui dans l'angle que forme l'aile intérieure 7 avec le fond du profilé 1b, ou plus exactement dans l'angle que forme la traverse 8 avec le fond de ce profilé. L'effort élastique exercé par le ressort sur la traverse 9 est dirigé selon la flèche F coplanaire au ressort. Une poignée 17 de manoeuvre du volet 3 est attelée à ce dernier au moyen d'une vis traversant le volet de manière connue.The cross member 9 has, on its other side, a groove 15 in which is housed a branch 16a of a plane spring 16 in a pin or S whose other branch 16b is supported in the angle formed by the inner wing 7 with the bottom of the profile 1b, or more exactly in the angle formed by the cross member 8 with the bottom of this profile. The elastic force exerted by the spring on the cross-member 9 is directed along the arrow F coplanar with the spring. A handle 17 for operating the shutter 3 is coupled to the latter by means of a screw passing through the shutter in a known manner.

Lorsque le volet 3 obture l'ouverture 2 (figure 1) le bourrelet 10 est logé dans la gorge 12, l'ensemble formant un premier palier d'articulation du volet sur le châssis. On voit que la direction F de l'effort exercé par le ressort 16 sur la traverse 9 passe au- dessus de l'articulation, créant un couple autour de l'articulation 10,12 tendant à faire tourner le volet 3 dans le sens contra-horaire. Cette rotation est empêchée par l'appui du volet 3 sur le joint 5. Dans cette position, du fait de l'angle A, le bourrelet 11 est éloigné de la gorge 13.When the flap 3 closes the opening 2 (Figure 1) the bead 10 is housed in the groove 12, the assembly forming a first articulation bearing of the flap on the frame. It can be seen that the direction F of the force exerted by the spring 16 on the cross-member 9 passes over the articulation, creating a torque around the articulation 10, 12 tending to rotate the flap 3 in the counter-direction. - schedule. This rotation is prevented by the support of the flap 3 on the seal 5. In this position, due to the angle A, the bead 11 is moved away from the groove 13.

Par une action sur la poignée 17 dans le sens horaire, on surmonte le couple de rappel susdit et la traverse 9 tourne par rapport à la traverse 1 b autour de l'articulation 10,12. Lorsque l'angle de rotation a atteint la valeur de l'angle A (par exemple 20°), le bourrelet 11 est engagé dans la gorge 13. Le plan du ressort 16 qui contient la direction F a pris la position de la figure 2 du fait de l'abaissement de la rainure 15 lors du pivotement de la traverse 9 autour de l'articulation 10,12. La direction F passe alors entre les deux gorges 12 et 13 de l'aile 6 du profilé 1b. La traverse 9 est maintenue en appui contre l'aile 6 et sa position est stable puisque le couple tendant à la faire tourner autour de l'articulation 10,12 est contrarié par un couple de sens contraire tendant à la faire tourner autour de l'articulation 11,13. Les dimensions de la traverse 9 et les positions relatives des gorges 12, 13 et 15 auront conduit, lors du pivotement, à une compression du ressort 16. L'effort de ce dernier sera plus important et d'intensité suffisante pour contrer avec sécurité l'effet de la pesanteur sur le volet 3 tendant à faire tourner ce dernier autour de l'articulation complexe 10-12, 11-13. L'inclinaison du volet est dans cette position égale à l'angle A.By acting on the handle 17 clockwise, the above-mentioned return torque is overcome and the cross-member 9 rotates relative to the cross-member 1b around the joint 10,12. When the angle of rotation has reached the value of the angle A (for example 20 ° ), the bead 11 is engaged in the groove 13. The plane of the spring 16 which contains the direction F has assumed the position of FIG. 2 due to the lowering of the groove 15 during the pivoting of the cross member 9 around the articulation 10,12. Direction F passes then between the two grooves 12 and 13 of the wing 6 of the profile 1b. The cross member 9 is held in abutment against the wing 6 and its position is stable since the torque tending to rotate it around the joint 10,12 is thwarted by a torque in the opposite direction tending to rotate it around the articulation 11.13. The dimensions of the cross-member 9 and the relative positions of the grooves 12, 13 and 15 will have led, during pivoting, to compression of the spring 16. The force of the latter will be greater and of sufficient intensity to counteract with safety l effect of gravity on the flap 3 tending to rotate the latter around the complex joint 10-12, 11-13. The inclination of the flap is in this position equal to the angle A.

La poursuite de l'action manuelle d'ouverture par l'intermédiaire de la poignée 7 fait pivoter le volet autour de l'articulation formée par le bourrelet 11 et la gorge 13. Le bourrelet 10 sort de la gorge 12 et le plan du ressort, donc la direction F passe de l'autre côté de l'articulation 11,13. A partir de ce passage, le ressort exerce un couple de sens horaire sur la traverse 9 et le volet 3 vient en appui contre le patin 8a de la traverse secondaire 8. C'est la position représentée à la figure 3. Cette position est également stable, l'ouverture du volet étant par exemple de 40°.Continuation of the manual opening action via the handle 7 makes the flap pivot around the articulation formed by the bead 11 and the groove 13. The bead 10 comes out of the groove 12 and the plane of the spring , therefore direction F passes on the other side of the joint 11,13. From this passage, the spring exerts a clockwise torque on the cross-member 9 and the flap 3 bears against the pad 8a of the secondary cross-member 8. This is the position shown in FIG. 3. This position is also stable, the opening of the shutter being for example 40 ° .

Pour modifier l'inclinaison du volet à partir de l'une de ses trois positions stables, il faut vaincre un couple de rappel exercé par le ressort. Cette résistance décroît pour s'annuler pour se transformer en une assistance au mouvement imprimé, ce chaque fois que le plan du ressort passe par l'un des axes des articulations 10, 12 ou 11,13. Cet effet est perceptible par l'usager et rend la manoeuvre du volet plus aisée.To modify the inclination of the flap from one of its three stable positions, it is necessary to overcome a return torque exerted by the spring. This resistance decreases in order to cancel out and transform into assistance with the printed movement, each time the plane of the spring passes through one of the axes of the joints 10, 12 or 11, 13. This effect is noticeable by the user and makes the operation of the shutter easier.

L'un des avantages importants de la structure selon l'invention réside dans le fait que la réalisation d'un volet basculant à trois positions stables ne nécessite aucune pièce supplémentaire par rapport aux dispositifs existants à deux positions.One of the important advantages of the structure according to the invention lies in the fact that the production of a tilting flap with three stable positions does not require any additional part compared to existing devices with two positions.

L'invention peut donc être mise en place dans tous les ensembles pouvant être équipés de volets connus. Cette disposition a une influence intéressante sur le prix de revient de la structure.The invention can therefore be implemented in all assemblies that can be equipped with known shutters. This arrangement has an interesting influence on the cost price of the structure.

L'invention trouve une application intéressante dans le domaine de la construction des voitures de véhicules de transport en commun.The invention finds an interesting application in the field of construction of cars for public transport vehicles.
