Abstract

The awning comprises a canopy for protecting the wound fabric and is of the type comprising, on the one hand, a stationary carrier structure (1) for a fabric-carrying roller (16) and articulated arms (6) and, on the other hand, a fabric (8) which is fixed by one of its ends to the fabric-carrying roller (16) and by the other of its ends to a load bar (7) which is fixed to the end of articulated arms (6) so that the fabric (8) can be wound over the fabric-carrying roller (16) or unwound from the latter, in order to be extended in a plane which is inclined to a greater or lesser extent. It is characterised in that it comprises an awning, separate and independent from the carrier structure (1), which is extended from the rear portion of the roller (16), and on top of this roller (16), in a front plane (21) limited by one edge overhanging at least as far in front of the roller (16) as is the load bar (7) when the fabric (8) is in the wound position, means being provided for locking the canopy in a position which is advantageously adjustable in relation to the stationary carrier structure (1), in which position its front plane is parallel to the fabric (8). <IMAGE>

Description

Une banne est un élément de protection comprenant une armature et une toile que l'on peut enrouler sur un tube, selon une longueur plus ou moins importante.A awning is a protective element comprising a frame and a canvas which can be wound on a tube, according to a more or less long length.

La toile subit un vieillissement d'autant plus prononcé qu'elle reste soumise aux intempéries, au rayonnement ultra-violet du soleil et aux souillures.The canvas undergoes an aging all the more pronounced that it remains subjected to the bad weather, to the ultraviolet radiation of the sun and to the stains.

Cela est donc plus marqué pour la partie de la toile qui n'est pas protégée par son enroulement sur le tube, c'est-à-dire l'extrémité basse de la toile, solidaire d'une barre de charge, et la partie de la toile qui n'est pas complétement enveloppée après enroulement.This is therefore more marked for the part of the canvas which is not protected by its winding on the tube, that is to say the lower end of the canvas, secured to a load bar, and the part canvas which is not completely wrapped after winding.

Pour remédier à cet inconvénient, on a déjà pensé à placer un auvent fixe.To overcome this drawback, we have already thought of placing a fixed awning.

Un tel auvent peut être réalisé selon différentes variantes connues qui peuvent être groupées en deux familles principales :Such a canopy can be produced according to various known variants which can be grouped into two main families:

Un première famille comprend les auvents rapportés, constitués d'une partie supérieure et parfois de joues latérales, fixés au-dessus de la banne (voir le document DE-C-3 428 153).A first family comprises the attached awnings, consisting of an upper part and sometimes of side cheeks, fixed above the awning (see document DE-C-3 428 153).

Ces auvents sont la plupart du temps fabriqués spécialement pour chaque banne et sont chers car, outre leur réalisation sur commande, ils doivent être robustes et rigides afin d'être en eux-mêmes suffisamment résistants pour pouvoir résister aux sollicitations qu'ils subissent : les efforts dus au vent pour l'essentiel et, bien entendu, leur propre poids. En effet, il sont fixés au-dessus de la banne et sont généralement indépendants de celle-ci. De plus, ils présentent une saillie d'autant plus importante que l'on donne à la toile une pente plus accentuée car ils doivent protéger celle-ci non seulement contre la pluie et les poussières tombant verticalement mais aussi contre celles qui l'atteignent obliquement.These awnings are mostly made specially for each awning and are expensive because, in addition to being made to order, they must be robust and rigid in order to be in themselves sufficiently resistant to be able to withstand the stresses they undergo: mainly wind forces and, of course, their own weight. Indeed, they are fixed above the awning and are generally independent of it. In addition, they have a projection all the more important that the canvas is given a more steep slope because they must protect it not only against the rain and dust falling vertically but also against those reaching it obliquely.

Les auvents de ce type sont de conception banale et n'ont pas donné lieu, en soi, à des dépôts de brevets.Canopies of this type are of ordinary design and have not, in themselves, given rise to patent applications.

Une deuxième famille comprend les coffres qui enveloppent tout l'ensemble de la banne et qui doivent être en eux-mêmes autoportants car il ne faut pas qu'ils gênent le fonctionnement de la banne et, par conséquent, ils doivent constituer en tout rigide et autonome.A second family includes the safes which envelop the whole of the awning and which must be self-supporting in themselves because they must not interfere with the functioning of the awning and, therefore, they must be made completely rigid and autonomous.

Un exemple d'un tel coffre est décrit dans le document FR-A-2 125 291. A l'examen de ce document, on comprend que le coffre ne constitue pas un véritable auvent mais une enveloppe complète dont la partie supérieure est immuable puisqu'elle constitue un élément fixe, de référence, avec lequel doit coopérer un élément mobile constitué par une "barre de chute" dont la forme est complémentaire de celle du coffre afin de fermer celui-ci quand la toile est complètement enroulée.An example of such a box is described in document FR-A-2 125 291. Upon examination of this document, it is understood that the box does not constitute a real awning but a complete envelope the upper part of which is immutable since 'it constitutes a fixed element, of reference, with which a mobile element must cooperate, constituted by a "drop bar" whose shape is complementary to that of the trunk in order to close the latter when the canvas is completely wound.

Dès lors que l'on accepte les inconvénients techniques et économiques de tels coffres autoportants, on profite généralement de leur lourdeur et de leur rigidité pour leur faire jouer un rôle de soutien du tube de toile dont on sait qu'il se déforme et prend une flèche quand il est relativement long, mince et donc flexible.As soon as we accept the technical and economic disadvantages of such freestanding boxes, we generally take advantage of their heaviness and their rigidity to make them play a supporting role for the canvas tube which we know to be deformed and takes a arrow when relatively long, thin and therefore flexible.

Dans le document FR-A-2 125 291, le coffre autoportant présente une paroi interne de forme circulaire pour recevoir directement le tube et la toile enroulée sur lui, sans qu'il soit nécessaire de prévoir des paliers pour le guidage en rotation du tube de toile. C'est donc le coffre qui donne la rigidité à l'ensemble.In document FR-A-2 125 291, the self-supporting trunk has an internal wall of circular shape for directly receiving the tube and the fabric wound on it, without it being necessary to provide bearings for the guiding in rotation of the tube Canvas. It is therefore the trunk which gives rigidity to the whole.

Ce problème de rigidité est indépendant de celui de la protection de la toile par un auvent comme le montre le document FR-A-2 223 542 qui décrit un compensateur de flèche qui ne comporte aucun auvent mais qui supporte un tube pour éviter qu'il ne fléchisse.This rigidity problem is independent of that of the protection of the fabric by a canopy as shown in document FR-A-2 223 542 which describes a deflection compensator which has no canopy but which supports a tube to prevent it don't falter.

Par conséquent, c'est un avantage spécifique au coffre autoportant décrit dans le document FR-A-2 125 291 que d'offrir à la fois l'avantage de soutenir le tube et l'avantage de protéger la toile.Consequently, it is a specific advantage of the self-supporting trunk described in document FR-A-2 125 291 to offer both the advantage of supporting the tube and the advantage of protecting the fabric.

En revanche, cette solution présente des inconvénients majeurs, et notamment celui d'être extrêmement chère, du fait en particulier du poids de matière nécessaire à la rigidité et à la solidité recherchées. La matière devant, en outre, nécessairement résister aux intempéries, on choisit généralement des alliages d'aluminium qui ont l'inconvénient d'avoir un prix est très élevé.On the other hand, this solution has major drawbacks, and in particular that of being extremely expensive, due in particular to the weight of material necessary for the desired rigidity and solidity. The material must, in addition, necessarily withstand the weather, aluminum alloys are generally chosen which have the disadvantage of being very expensive.

D'un point de vue strictement fonctionnel, un tel coffre autoportant ne permet pas d'ajuster la position de la partie supérieure du coffre (comparable à un auvent) en fonction de l'inclinaison de la toile car elle est donnée par les bras de manoeuvre dont la position est déterminée par réglage d'un ensemble vis-écrou, tandis que la partie supérieure du coffre est immuable.From a strictly functional point of view, such a self-supporting trunk does not make it possible to adjust the position of the upper part of the trunk (comparable to an awning) according to the inclination of the canvas since it is given by the arms of maneuver whose position is determined by adjusting a screw-nut assembly, while the upper part of the trunk is immutable.

La présente invention remédie à tous les inconvénients rappelés ci-dessus en permettant de réaliser une banne dont l'inclinaison est réglable et dont la toile est toujours protégée par un auvent léger et bon marché.The present invention overcomes all the drawbacks mentioned above by making it possible to produce a awning whose inclination is adjustable and whose fabric is always protected by a light and inexpensive awning.

A cette fin, l'invention a pour objet une banne comprenant un auvent de protection de la toile enroulée, du type comprenant d'une part une structure porteuse fixe pour un rouleau porte-toile et des bras articulés et d'autre part une toile qui est fixée par l'une de ses extrémités au rouleau porte-toile et par l'autre de ses extrémités à une barre de charge qui est fixée à l'extrémité de bras articulés afin que la toile puisse être enroulée sur le rouleau porte-toile ou déroulée de ce dernier, pour s'étendre dans un plan plus ou moins incliné, le rouleau porte-toile étant associé à un auvent relié à un support situé sous ledit rouleau porte-toile et qui s'étend depuis la partie postérieure du rouleau, et par-dessus ce rouleau selon un plan antérieur limité par un bord situé en surplomb au moins aussi loin en avant du rouleau que l'est la barre de charge quand la toile est en position enroulée, caractérisée en ce que l'auvent :

Sur l'élément porteur 1 sont également fixés des bras (non représentés) qui s'étendent depuis l'élément porteur 1 jusqu'à une barre de charge 2, leur longueur étant réglable. Ces bras, de tout type connu, portent et guident la barre de charge 2, selon une disposition classique qui ne nécessite donc pas une description détaillée.Arms (not shown) are also attached to the support element 1 which extend from the support element 1 to a load bar 2, their length being adjustable. These arms, of any known type, carry and guide the load bar 2, according to a conventional arrangement which therefore does not require a detailed description.

La barre de charge 2 reçoit une extrémité d'une toile 3 dont l'extrémité opposée est assujettie à un tube 4 relié cinématiquement à un mécanisme de manoeuvre tel qu'un moteur, une manivelle etc. de tout type connu (non représenté), afin qu'il puisse être entraîné en rotation selon son axe x dans l'un quelconque des deux sens opposés.The load bar 2 receives one end of a fabric 3, the opposite end of which is subjected to a tube 4 kinematically connected to an operating mechanism such as a motor, a crank, etc. of any known type (not shown), so that it can be rotated along its x axis in any of two opposite directions.

Quand le tube 4 est entraîné dans le sens des aiguilles d'une montre, en considérant l'extrémité visible sur la figure 1, il tire sur la toile 3 qui elle-même tire sur la barre de charge 2, les bras porteurs se rétractant tout en asurant le maintien de la barre de charge 2 et son alignement parallèlement à l'axe x du tube 4.When the tube 4 is driven in a clockwise direction, considering the end visible in FIG. 1, it pulls on the fabric 3 which itself pulls on the load bar 2, the carrying arms retracting while ensuring the maintenance of the load bar 2 and its alignment parallel to the axis x of the tube 4.

Quand le tube 4 est entraîné dans le sens inverse des aiguilles d'une montre (toujours en considérant l'extrémité visible sur la figure 1), la toile 3 est libérée et laisse les bras porteurs se déployer jusqu'à l'arrêt de la rotation du tube 4.When the tube 4 is driven anticlockwise (always considering the end visible in FIG. 1), the fabric 3 is released and lets the carrying arms unfold until the stop of the tube rotation 4.

L'orientation du plan dans lequel la toile 3 s'étend lorsqu'elle est déployée dépend du réglage de la position des bras par rapport à l'élément porteur 1, ce montage étant classique et bien connu de l'homme de métier.The orientation of the plane in which the fabric 3 extends when it is deployed depends on the adjustment of the position of the arms relative to the support element 1, this assembly being conventional and well known to those skilled in the art.

Selon les circonstances, on effectue une réglage plutôt qu'un autre afin que la toile soit plus ou moins verticale et, de ce fait, ait une "avancée" plus ou moins
   grande et une hauteur libre sous la barre de charge 2 plus ou moins importante.Depending on the circumstances, one adjustment is made rather than another so that the canvas is more or less vertical and, therefore, has a "projection" more or less
large and a free height under the load bar 2 more or less important.

Conformément à l'invention, un auvent 10 est placé au-dessus de la banne et s'étend sur une distance D qui se mesure depuis l'arrière de la banne jusqu'à l'aplomb, au moins, de la partie la plus avancée de la barre de charge 2 dans la position qu'elle occupe quand la toile 3 est complétement enroulée sur le tube 4.According to the invention, an awning 10 is placed above the awning and extends over a distance D which is measured from the rear of the awning to the plumb, at least, of the most projection of the load bar 2 in the position it occupies when the fabric 3 is completely wound on the tube 4.

Par "partie arrière", on désigne essentiellement la partie postérieure du tube 4, c'est-à-dire sa génératrice la plus proche du plan de la baie équipée, génératrice considérée lorsque le maximum de toile 3 est enroulée sur le tube 4 puisque le but premier de l'auvent 10 est de protéger la toile.By “rear part”, one essentially designates the rear part of the tube 4, that is to say its generator closest to the plane of the fitted bay, generator considered when the maximum of fabric 3 is wound on the tube 4 since the primary purpose of awning 10 is to protect the fabric.

Ici, l'auvent 10 comprend un plan antérieur 11 ayant un bord relevé 12 et se prolongeant par une partie inférieure 13 qui entoure le tube 4 et la toile 3 enroulée sur lui.Here, the canopy 10 comprises a front plane 11 having a raised edge 12 and extending by a lower part 13 which surrounds the tube 4 and the fabric 3 wound on it.

L'auvent 10 comprend ainsi, en une seule pièce, le plan antérieur 11 et une coquille 13 à section circulaire coaxiale au tube 4.The canopy 10 thus comprises, in a single piece, the front plane 11 and a shell 13 of circular section coaxial with the tube 4.

Il est donc possible de faire pivoter l'ensemble de l'auvent 10 selon l'axe x aussi bien dans un sens que dans l'autre afin d'orienter le plan antérieur 10 de telle sorte qu'il soit parallèle à la toile 3 quand celle-ci est complètement enroulée.It is therefore possible to rotate the assembly of the canopy 10 along the x axis both in one direction and in the other in order to orient the anterior plane 10 so that it is parallel to the fabric 3 when it is completely rolled up.

Cette possibilité de mouvement doit néanmoins être contrôlée car chaque action sur le rouleau 4 pour enrouler ou dérouler la toile 3 peut avoir tendance à déplacer l'auvent 10, ce qui n'est pas le but recherché. Au contraire, s'il faut pouvoir orienter différemment l'auvent 10 selon l'inclinaison de la toile 3, il faut aussi maintenir cette orientation, quels que soient .les mouvements de ladite toile 3 en service normal.This possibility of movement must nevertheless be controlled because each action on the roller 4 to wind or unwind the fabric 3 may tend to move the awning 10, which is not the aim. On the contrary, if it is necessary to be able to orient the awning differently 10 according to the inclination of the fabric 3, it is also necessary to maintain this orientation, whatever the movements of said fabric 3 in normal service.

C'est pourquoi on prévoit des moyens d'immobilisation de l'auvent 10.This is why means for immobilizing the awning 10 are provided.

Un exemple de réalisation de ces moyens va être décrit maintenant.An exemplary embodiment of these means will now be described.

La coquille 13 se redresse vers l'avant et se termine par un bord arrondi 14 situé près de la face inférieure du plan antérieur 11, la toile 3 pouvant sans inconvénient glisser sur lui puisqu'il a une forme courbe et une surface lisse.The shell 13 straightens forward and ends with a rounded edge 14 located near the underside of the anterior plane 11, the fabric 3 being able to slide over it without any drawback since it has a curved shape and a smooth surface.

Un berceau rigide 15 présente une partie médiane en arc de cercle qui se termine vers l'avant par un bourrelet de raidissage 16 dont le profil extérieur est coordonné au profil intérieur du bord arrondi 14, afin que le bourrelet 16 soit bien appliqué, et même pincé par déformation élastique du bord arrondi 14, dans la volute dudit bord arrondi 14, ce qui solidarise l'auvent 10 et le berceau 15 en pivotement axial.A rigid cradle 15 has a central part in an arc of a circle which terminates towards the front by a stiffening bead 16 whose external profile is coordinated with the internal profile of the rounded edge 14, so that the bead 16 is properly applied, and even pinched by elastic deformation of the rounded edge 14, in the volute of said rounded edge 14, which secures the canopy 10 and the cradle 15 in axial pivoting.

Le berceau 15 est engagé dans un guide circulaire 17 d'un support 18 bloqué sur l'élément porteur 1 au moyen d'au moins un boulon 19 après qu'il ait été engagé sur ledit élément porteur 1 par une mâchoire 20 de section correspondante.The cradle 15 is engaged in a circular guide 17 of a support 18 locked on the carrier element 1 by means of at least one bolt 19 after it has been engaged on said carrier element 1 by a jaw 20 of corresponding section .

Quand le ou les boulons 19 sont serrés, le support 18 est solidement fixé à l'élément porteur 1 et est dont parfaitement immobile.When the bolt (s) 19 are tightened, the support 18 is securely attached to the carrier element 1 and is therefore perfectly stationary.

Le berceau 15, quant à lui, peut pivoter autour de l'axe x en coulissant dans le guide 17 et c'est par ce mouvement que l'on ajuste l'orientation de l'auvent 10 par rapport à la pente de la toile 3, laquelle dépend du réglage effectué à l'emplacement de la fixation de ceux-ci sur l'élément porteur 1.The cradle 15, for its part, can pivot around the x axis by sliding in the guide 17 and it is by this movement that the orientation of the awning 10 is adjusted relative to the slope of the fabric. 3, which depends on the adjustment made at the location of the fixing of these on the carrier element 1.

Pour bloquer l'auvent 10 en bonne position, on prévoit au moins une vis 21 engagée dans un trou taraudé du support 18 et débouchant en regard du bord extérieur du berceau 15. Cette vis agit très efficacement et suffit à rendre le berceau 15 (et donc l'auvent 10) parfaitement immobiles, puisque solidaires de l'élément porteur 1, par l'intermédiaire du support 18.To block the canopy 10 in good position, at least one screw 21 is provided, engaged in a tapped hole in the support 18 and emerging opposite the outer edge of the cradle 15. This screw acts very effectively and is sufficient to make the cradle 15 (and therefore the canopy 10) perfectly stationary, since they are integral with the carrier element 1, by means of the support 18.

Pour assurer la solidarisation en pivotement de l'auvent 10 et du berceau 15, aussi bien dans un sens que dans l'autre, on prévoit un crochet extérieur 22 qui reçoit un bourrelet de raidissage 23 du berceau 15 symétrique et, ici, identique au bourrelet 16. Avec ces dispositions, la liaison de l'auvent 10 et du berceau 15 par le bord arrondi 14 et par le crochet 22 recevant les bourrelets 16 et 23 est indépendante du sens dans lequel on exerce un effort pour modifier l'orientation de l'auvent 10.To secure the pivoting of the awning 10 and the cradle 15, both in one direction and in the other, an external hook 22 is provided which receives a stiffening bead 23 of the cradle 15 symmetrical and, here, identical to the bead 16. With these arrangements, the connection of the awning 10 and the cradle 15 by the rounded edge 14 and by the hook 22 receiving the beads 16 and 23 is independent of the direction in which an effort is exerted to modify the orientation of awning 10.

En rendant continu sur toute la longueur de l'auvent 10 le bord relevé 12, le bord arrondi 14 et le crochet extérieur 2 2, on rigidifie l'auvent 10 qui conserve une raideur et une indéformabilité importantes.By making continuous over the entire length of the canopy 10 the raised edge 12, the rounded edge 14 and the outer hook 2 2, the canopy 10 is stiffened, which retains considerable stiffness and non-deformability.

En outre, on prévoit au moins deux ensembles berceau 15 -support 18 pour équilibrer les efforts et les points d'appui.In addition, at least two cradle 15 -support 18 assemblies are provided to balance the forces and the support points.

On se trouve devant un choix, selon que l'on dispose ou pas d'un tube d'enroulement 4 très rigide.We are faced with a choice, depending on whether or not we have a very rigid winding tube 4.

S'il est très rigide, l'auvent 10 acquiert sa rigidité par son contact avec le tube 4 puisque celui-ci repose sur la coquille continue 13.If it is very rigid, the canopy 10 acquires its rigidity by its contact with the tube 4 since the latter rests on the continuous shell 13.

Mais on peut aussi obtenir un effet de raidissage du tube 4 par la coquille 13, du fait que celle-ci repose sur des supports 18 robustes et bien répartis le long de l'élément porteur 1.However, it is also possible to obtain a stiffening effect on the tube 4 by the shell 13, owing to the fact that the latter rests on robust supports 18 well distributed along the carrier element 1.

L'auvent 10 joue alors le rôle de compensateur de flèche et peut rendre inutile d'autres supports intermédiaires entre les deux extrémités du tube d'enroulement 4, pour des bannes de grande longueur.The canopy 10 then acts as a deflection compensator and can make unnecessary other intermediate supports between the two ends of the winding tube 4, for banners of great length.

En comparant les figures 1 et 2, on voit que les éléments fixes sont disposés identiquement et que, en revanche, l'auvent 10 et son berceau 15 ont pivoté : sur la figure 1 le plan antérieur 11 de l'auvent 10 est parallèle à une toile 3 peu inclinée alors que sur la figure 2, le plan antérieur 11 est parallèle à une toile 3 très inclinée.By comparing Figures 1 and 2, we see that the fixed elements are arranged identically and that, in on the other hand, the canopy 10 and its cradle 15 have pivoted: in FIG. 1 the front plane 11 of the canopy 10 is parallel to a fabric 3 slightly inclined whereas in FIG. 2, the anterior plane 11 is parallel to a fabric 3 very inclined.

L'auvent 10 peut être réalisé en toute matière appropriée telle qu'une matière synthétique. Il peut aussi être à paroi alvéolaire, ce qui associe légéreté et rigidité.The canopy 10 can be made of any suitable material such as a synthetic material. It can also have a honeycomb wall, which combines lightness and rigidity.
