Abstract

1. Awning comprising, on the one hand, a rotary roller, a loading bar and a web which is rolled on the roller and which is fixed by its free edge to the loading bar, and on the other hand, supports (3 and 4) and struts, the arms (1 and 2) of which, being articulated together, are movable in a single virtual plane and are, moreover, each articulated by one of their end to a support (3-4) and by the other of their ends to the single loading bar, the various articulation pivots of the struts all having an axis perpendicular to the plane of the struts, while the supports (3 and 4) are integral with a bar (5) parallel to the loading bar, characterised in that this bar (5) is pivotably mounted in bearings (6 and 7) which are fixed below the roller and which are of the type involving permanent friction, of which the value, preferably adjustable, is set below a blocking value, in order that it is possible, without action on the bearings, for the awning to be pivotally displaced.

Description

L'invention a pour objet un store du type banne c'est-à-dire comprenant d'une part une toile tendue entre un rouleau et une barre de charge et d'autre part des bras articulés reliés par l'une de leurs extrémités à la barre de charge et par leur autre extrémité à des supports montés pivotant autour d'un axe parallèle à la barre de charge afin de pouvoir ajuster l'inclinaison de la toile.The subject of the invention is a blind of the awning type, that is to say comprising on the one hand a fabric stretched between a roller and a load bar and on the other hand articulated arms connected by one of their ends to the load bar and by their other end to supports mounted pivoting about an axis parallel to the load bar in order to be able to adjust the inclination of the canvas.

Ces dispositions connues permettent à l'usager d'incliner plus ou moins la toile du store selon les circonstances et, en particulier, selon les saisons pour que l'ombre que procure la toile soit placée au mieux.These known arrangements allow the user to tilt the awning fabric more or less depending on the circumstances and, in particular, depending on the season so that the shade provided by the fabric is best placed.

L'inclinaison ajustable est difficile à obtenir compte tenu des contraintes qu'apporte l'armature générale de la banne surtout si celle-ci est de grandesdimensions.The adjustable inclination is difficult to obtain given the constraints brought by the general frame of the awning, especially if it is of large dimensions.

Ainsi par exemple dans le brevet français 2.127.434 est décrit un store du type banne qui comprend un "porte-store" muni d'une barre de torsion qui sert de liaison entre ce prote-store et des supports fixes. La barre de torsion, outre son rôle de liaison mécanique, a pour but de créer une pré-contrainte grâce à laquelle l'effort à fournir pour faire pivoter le porte-store est plus faible que ce qu'il serait en l'absence de barre de torsion.Thus, for example, in French patent 2,127,434, a blind of the awning type is described which comprises a "blind holder" provided with a torsion bar which serves as a link between this prote-blind and fixed supports. The torsion bar, in addition to its role of mechanical connection, aims to create a pre-stress thanks to which the effort to be made to pivot the blind holder is lower than what it would be in the absence of torsion bar.

En conséquence, il est nécessaire de bloquer le porte-store dans l'orientation finalement choisie car le moindre souffle de vent, par exemple, suffirait à modifier cette orientation.Consequently, it is necessary to block the awning in the orientation finally chosen because the slightest breath of wind, for example, would be enough to modify this orientation.

Selon ce brevet la partie mobile du porte-store est équipée d'une ou plusieurs têtes de serrage permettant de bloquer le store dans la position désirée.According to this patent, the movable part of the blind holder is equipped with one or more clamping heads making it possible to block the blind in the desired position.

Lorsque l'on veut modifier l'orientation de la toile, il est donc nécessaire au préalable d'effectuer la manoeuvre qui consiste à obtenir le déblocage.When you want to change the orientation of the canvas, it is therefore necessary beforehand to perform the maneuver which consists in obtaining the release.

Selon la présente invention, les efforts de poids et de sollicitations au pivotement sont entièrement et exclusivement supportés par les paliers ou supports 6 et 7 dont on règle convenablement la valeur de résistance.According to the present invention, the efforts of weight and stress pivoting are entirely and exclusively supported by bearings or supports 6 and 7, the resistance value of which is suitably adjusted.

Cela est contraire au montage prévu par le brevet français 2.127.434 qui prévoit toujours la présence de barres de torsion entre le "porte-store" et les supports ou paliers 6, la tête de serrage 8 n'étant là que pour bloquer le store dans la position désirée comme cela est précisé page 2 ligne 25 de ce brevet.This is contrary to the assembly provided for by French patent 2,127,434 which still provides for the presence of torsion bars between the "blind holder" and the supports or bearings 6, the clamping head 8 being there only to block the blind. in the desired position as specified on page 2 line 25 of this patent.

Dans le certificat d'addition français 2.214.035 au brevet ci-dessus, ont été décrits des perfectionnements selon lesquels on prêvoi.t une commande positive de l'inclinaison du porte-store grâce à laquelle la manoeuvre de réglage de l'inclinaison est facilitée pour ne nécessiter aucune dépense physique de la part de l'utilisateur.In the French certificate of addition 2,214,035 to the above patent, improvements have been described according to which a positive control of the inclination of the awning holder is provided, by which the tilt adjustment maneuver is facilitated so as not to require any physical expenditure on the part of the user.

Par le brevet français 1.396.200 on connait un store dont chaque bras est indépendant et comporte un joint à friction.By French patent 1,396,200 a blind is known, each arm of which is independent and has a friction joint.

Il s'agit de toute évidence, à l'examen des figures du dessin, d'un store de très petites dimensions qu'il est possible de manoeuvrer à hauteur d'homme, de sorte qu'il est indifférent que les deux joints à friction soient indépendants car si'l'on agit sur la barre <de charge 3 pour abaisser le store, les joints à friction sont sollicités plus ou moins selon l'endroit exact où se situe le point d'application de l'effort mais on peut supposer qu'en agissant avec les deux mains, a peu près symétriquement, la toile sera finalement tant bien que mal abàis- sée convenablement.It is obviously, on examination of the figures of the drawing, a blind of very small dimensions that it is possible to operate at height of man, so that it is immaterial that the two joints to friction are independent because if we act on the <load bar 3 to lower the blind, the friction joints are stressed more or less depending on the exact place where the point of application of the force is located but we may suppose that by acting with the two hands, almost symmetrically, the canvas will ultimately be somehow properly lowered.

Il n'en est pas du tout de même pour les bannes de grandes dimensions dont le mécanisme est situé à plusieurs mètres de hauteur (tambour d'enroulement de la toile, points d'application des bras, etc...) et dont la barre de charge peut avoir huit ou dix mètres de long.It is not at all the same for large banners whose mechanism is located several meters high (canvas winding drum, points of application of the arms, etc.) and whose load bar can be eight or ten meters long.

Pour changer l'orientation des bras d'une telle banne, il est alors indispensable d'abord de monter sur une échelle, ce qui est incommode, et ensuite d'agir successivement sur chacun des joints à friction pour assurer leur déblocage et permettre à un bras, puis à l'autre de s'abaisser ou d'être redressé.To change the orientation of the arms of such a shutter, it is then essential first to climb a ladder, which is inconvenient, and then to act successively on each of the friction joints to ensure their release and allow one arm, then the other to lower or be straightened.

La manoeuvre de chacun de ces bras suppose que l'on développe des efforts considérables représentant plusieurs dizaines de kilos et nécessite l'intervention d'au moins deux hommes et bien souvent le calage de la barre de charge avec des moyens de fortune.The operation of each of these arms assumes that considerable efforts are made, representing several tens of kilos, and require the intervention of at least two men and very often the setting of the load bar with makeshift means.

Dans le brevet français 1.550.331 est décrit un dispositif qui comprend une barre carrée sur laquelle les bras sont assujettis, mais comme cela est exprimé page 1, colonne 2 lignes 32 et suivantes, cette barre 4 est serrée entre les deux branches 6 dans le fond 7 d'un étrier 1 au moyen d'un boulon 8 traversant les deux branches 6.In French patent 1,550,331, a device is described which includes a square bar on which the arms are secured, but as expressed on page 1, column 2 lines 32 and following, this bar 4 is clamped between the two branches 6 in the bottom 7 of a stirrup 1 by means of a bolt 8 crossing the two branches 6.

Les bras 32 sont fixés à la barre 4 au moyen d'une bague 24 qui est bloquée par une vis 51 dans la position choisie comme cela est précisé paga 2 dernier paragraphe de la colonne 1 et premier paragraphe de la colonne 2.The arms 32 are fixed to the bar 4 by means of a ring 24 which is locked by a screw 51 in the chosen position as is specified paga 2 last paragraph of column 1 and first paragraph of column 2.

Il résulte du même passage de la description que le desserrage de la vis 51 a pour effet de débloquer la bague 24 par rapport à la barre 4 de sorte qu'il est possible de procéder au réglage angulaire des bras 32.It follows from the same passage in the description that the loosening of the screw 51 has the effect of unlocking the ring 24 relative to the bar 4 so that it is possible to make the angular adjustment of the arms 32.

Ce montage n'est pas satisfaisant puisque le réglage angulaire de l'ensemble du store exige le réglage de chaque bras indépendamment de l'autre et rend impossible un réglage aisé et fréquent et même, pourrait-on dire, ad libitum puisque le desserrage d'un seul bras a pour conséquence de provoquer la chute de celui-ci et la torsion de la toile à moins que, par des moyens aléatoires, on ait pu le caler en hauteur provisoirement pendant que l'on procède au réglage de l'autre bras, etc...This assembly is not satisfactory since the angular adjustment of the entire blind requires the adjustment of each arm independently of the other and makes impossible an easy and frequent adjustment and even, one could say, ad libitum since the loosening of '' only one arm has the effect of causing it to fall and the canvas to twist unless, by random means, it has been possible to temporarily block it in height while the other is being adjusted arms, etc ...

Le brevet français 1.558.274 décrit un store du même type que ceux décrits dans les brevets français 1.396.200 et 1.550.331, à savoir que les bras sont individuellement réglables en inclinaison par rapport à une barre a qui est fixe ainsi que cela est expliqué page 1, colonne 1, lignes 24 à 26.French patent 1,558,274 describes a blind of the same type as those described in French patents 1,396,200 and 1,550,331, namely that the arms are individually adjustable in inclination relative to a bar a which is fixed as is explained on page 1, column 1, lines 24 to 26.

Le store conforme à l'invention diffère de ces dispositifs connus en ce qu'il comprend des bras qui sont fixés sur une barre commune, laquelle est montée dans des paliers fixes comportant un système de friction de préférence réglable.The blind according to the invention differs from these known devices in that it comprises arms which are fixed to a common bar, which is mounted in fixed bearings comprising a friction system preferably adjustable.

Selon l'invention il est impossible de faire pivoter les bras sans simultanément faire pivoter la barre qui les réunit.According to the invention it is impossible to rotate the arms without simultaneously rotating the bar which joins them.

On reconstitue, en haut par une barre (ou tube) la réunion rigide d'en bas par la barre de charge.We reconstitute, at the top by a bar (or tube), the rigid union from below by the load bar.

Ce dispositif et d'autres connus par ailleurs ont pour inconvénient de nécessiter des mécanismes relativement complexes et très robustes du fait que l'effort de poids de tout l'ensemble mobile agit sur le mécanisme par le quel on obtient une modification de l'inclinaison.This device and others known elsewhere have the drawback of requiring relatively complex and very robust mechanisms because the weight force of the entire mobile assembly acts on the mechanism by which a modification of the inclination is obtained. .

En outre, les dispositifs connus agissent par tout ou rien selon que l'on bloque ou que l'on débloque la partie mobile avant de la dé placer.In addition, the known devices act by all or nothing according to that we block or unblock the moving part before moving it.

La présente invention a pour but de simplifier la construction de telles bannes en vue de les rendre non seulement plus pratiques mais également plus économiques.The present invention aims to simplify the construction of such banners in order to make them not only more practical but also more economical.

L'invention sera bien comprise par la description détaillée ci-après faite en référence au dessin annexé. Bien entendu, la description et le dessin ne sont donnés qu'à titre d'exemple indicatif et non limitatif.The invention will be better understood from the detailed description below made with reference to the accompanying drawing. Of course, the description and the drawing are given only by way of an indicative and nonlimiting example.

La figure unique du dessin est une vue schématique partielle du store conforme à l'invention.The single figure of the drawing is a partial schematic view of the blind according to the invention.

Le store selon l'invention est du type banne, c'est-à-dire comprenant une armature devant être fixée près d'une baie d'une paroi et composée d'une part d'une toile tendue entre un rouleau et une barre de charge et d'autre part de bras articulés reliés par l'une de leursextrémités à la barre de charge et par leur autre extrémité à des supports montés pivotants autour d'un axe parallèle à la barre de charge afin de pouvoir ajuster l'inclinaison de la toile, caractérisé en ce que les supports sont assujettis à une barre commune continue dont les extrémités sont engagées de manière pivotante dans des paliers qui sont fixés à la paroi à équiper et qui sont du type à friction permanente dont la valeur est de préférence réglable, la manoeuvre qui consiste à ajuster l'inclinaison de la toile devant nécessiter un effort supérieur et antagoniste à celui pré-établi de la friction.The blind according to the invention is of the awning type, that is to say comprising a frame to be fixed near a bay of a wall and composed on the one hand of a fabric stretched between a roller and a bar load and on the other hand of articulated arms connected by one of their ends to the load bar and by their other end to supports pivotally mounted about an axis parallel to the load bar in order to be able to adjust the inclination of the fabric, characterized in that the supports are subject to a continuous common bar, the ends of which are pivotally engaged in bearings which are fixed to the wall to be fitted and which are of the permanent friction type, the value of which is preferably adjustable, the maneuver which consists in adjusting the inclination of the fabric having to require a greater and antagonistic effort than that pre-established of friction.

Un tel store est représenté sur le dessin où l'on voit des bras articulés 1 et 2 reliés par l'une de leurs extrémités à une barre de charge (non représentée) et par leur autre extrémité à des supports 3-4 placés sur une barre 5 dont les extrémités sont engagées dans des paliers à friction 6 et 7 fixés par tous moyens de préférence réglables à la façade qui doit recevoir la banne.Such a blind is shown in the drawing where we see articulated arms 1 and 2 connected by one of their ends to a load bar (not shown) and by their other end to supports 3-4 placed on a bar 5, the ends of which are engaged in friction bearings 6 and 7 fixed by any means, preferably adjustable, to the front which must receive the awning.

Les paliers 6 et 7 contiennent des surfaces à fort coefficient de friction soit interchangeables, soit du fait de leur relative rugosité.The bearings 6 and 7 contain surfaces with a high coefficient of friction either interchangeable or due to their relative roughness.

Avec ce dispositif, la barre 5 est constamment immobilisée dans l'orientation qu'elle occupe grâce à la friction obtenue dans les paliers 6 et 7 contre les garnitures, le tout étant réalisé par des moyens qui sont à la portée de l'homme de métier.With this device, the bar 5 is constantly immobilized in the orientation which it occupies thanks to the friction obtained in the bearings 6 and 7 against the linings, the whole being produced by means which are within the reach of man from job.

La friction est permanente et est établie à une valeur suffisante .pour s'opposer au pivotement accidentel de la barre 5 par exemple sous l'effet du vent normal agissant sur la toile que les bras articulés 1 et 2 maintiennent tendue.The friction is permanent and is established at a sufficient value. To oppose the accidental pivoting of the bar 5 for example under the effect of normal wind acting on the canvas that the articulated arms 1 and 2 keep taut.

Grâce à l'invention, il est possible de ne prévoir aucun organe de blocage pour s'opposer d'une manière positive à ce pivotement.Thanks to the invention, it is possible to provide no blocking member to positively oppose this pivoting.

Selon une caractéristique de l'invention, la barre reçoit au moins un élément tel qu une roue à rochet susceptible de recevoir l'action d'un outil de manoeuvre à levier tel qu'une clef et analogue.According to a characteristic of the invention, the bar receives at least one element such as a ratchet wheel capable of receiving the action of a lever operating tool such as a wrench and the like.

Sur le dessin, on a représenté deux roues à rochet respectivement 8 et 9, l'une ayant des dents inclinées dans un sens et l'autre des dents inclinées dans le sens opposé.In the drawing, there are shown two ratchet wheels respectively 8 and 9, one having teeth inclined in one direction and the other of teeth inclined in the opposite direction.

Avec une clef A de type connu, on peut agir sur l'une ou l'autre des roues à rochet 8-9 pour obliger la barre 5 à pivoter à l'encontre de l'effort de friction développé par les paliers 6 et 7.With a key A of known type, one can act on one or the other of the ratchet wheels 8-9 to force the bar 5 to pivot against the friction force developed by the bearings 6 and 7 .

Selon une variante de réalisation, la barre a une section non circulaire telle que carrée, et l'élément est engagé sur elle par un passage de même section, un organe d'immobilisation en coulissement étant éventuellement prévu sur l'élément pour coopérer avec la barre.According to an alternative embodiment, the bar has a non-circular section such as square, and the element is engaged on it by a passage of the same section, a sliding immobilization member being possibly provided on the element to cooperate with the closed off.

Avec le mode de réalisation représenté, cela signifie que les deux roues à rochet 8-9 ont un passage central de section carrée et sont engagées sur la barre 5. Une action avec la clef A sur l'une des deux roues à rochet 8-9 a pour effet d'entraîner la barre 5 en pivotement puisque le passage carré des roues à rochet s'oppose au pivotement de celles-ci par rapport à la barre 5, elle-même de section carrée.With the embodiment shown, this means that the two ratchet wheels 8-9 have a central passage of square section and are engaged on the bar 5. An action with the key A on one of the two ratchet wheels 8- 9 has the effect of driving the bar 5 in pivoting since the square passage of the ratchet wheels opposes the pivoting of the latter relative to the bar 5, itself of square section.

Lorsque l'on agit sur la roue 8 dans le sens de la flèche Fl les bras articulés 1 et 2 sont soulevés sans le sens des flèches fI. Lorsque avec la même clef A on agit cette fois-ci sur la roue à rochet 9 dans le sens de la flèche F2 les bras articulés 1 et 2 s'abaissent sans le sens des flèches f2.When one acts on the wheel 8 in the direction of the arrow F1 the articulated arms 1 and 2 are raised without the direction of the arrows fI. When, with the same key A, this time acts on the ratchet wheel 9 in the direction of the arrow F2, the articulated arms 1 and 2 are lowered without the direction of the arrows f2.

Dans le premier cas on tend à relever la toile vers l'horizontale tandis que dans le second cas on tend à l'abaisser. Selon la hauteur du soleil on peut faire varier l'ombre portée pour l'augmenter ou pour la diminuer.In the first case we tend to raise the canvas horizontally while in the second case we tend to lower it. Depending on the height of the sun, the shadow can be varied to increase or decrease it.

La roue à rochet 8 peut librement coulisser le long de la barre 5 selon la double flèche F3, dans un sens ou dans l'autre ce qui permet à l'utilisateur de la placer à l'endroit qui lui semble le meilleur et éventuellement de modifier cet emplacement quand il le veut.The ratchet wheel 8 can freely slide along the bar 5 according to the double arrow F3, in one direction or the other which allows the user to place it in the place which seems to him the best and possibly change this location whenever he wants.

La roue à rochet 9 est équipée d'une vis radiale 10 qui prend appui contre la barre 5 quand on la visse afin de s'opposer au libre coulissement de.la roue à rochet 9 le long de la barre 5.The ratchet wheel 9 is equipped with a radial screw 10 which bears against the bar 5 when it is screwed in order to oppose the free neck smoothing the ratchet wheel 9 along the bar 5.

Cette solution un peu différente de celle qui a été décrite pour la roue 8 permet d'immobiliser la roue 9 et de s'opposer à son coulissement après l'avoir placée à l'aidroit choisi.This solution, which is a little different from that which has been described for the wheel 8, makes it possible to immobilize the wheel 9 and to oppose its sliding after having placed it at the right location.

Bien entendu, on pourrait prévoir les deux séries de dents sur une même pièce libre ou pas, ou utiliser d'autres dispositions connues en soi pour permettre l'application d'un effort au moyen d'un outil.Of course, one could provide the two sets of teeth on the same free part or not, or use other arrangements known per se to allow the application of a force by means of a tool.

Dans la pratique, l'effort de friction des paliers 6 et 7 doit être relativement important compte-tenu-de la surface de la toile, du poids de l'ensemble et des sollicitations extérieures telles que, essentiellement, la force du vent.In practice, the friction force of the bearings 6 and 7 must be relatively large taking into account the surface of the fabric, the weight of the assembly and the external stresses such as, essentially, the force of the wind.

En conséquence, l'outil A doit procurer un bras de levier relativement important pour qu'un utilisateur puisse orienter la toile sans fatigue excessive.Consequently, the tool A must provide a relatively large lever arm so that a user can orient the fabric without excessive fatigue.

Selon une autre variante on peut associer à la barre 5 un mécanisme d'entraînement de tout type connu tel que ceux habituellement choisis pour manoeuvrer les stores :

  • - manivelles, tiges et renvoi d'angles, etc...
According to another variant, it is possible to associate with the bar 5 a drive mechanism of any known type such as those usually chosen for operating the blinds:
  • - cranks, rods and angular gear, etc ...

On remarque que selon l'invention les efforts de poids et de sollicitation au pivotement de la barre 5 sont entièrement et exclusivement supportés par les paliers 6 et 7 dont on règle convenablement la valeur de résistance. De ce fait, le mécanisme éventuellement associé à la barre 5 ne subit aucune sollicitation.It will be noted that according to the invention, the efforts of weight and of stress on pivoting of the bar 5 are entirely and exclusively supported by the bearings 6 and 7, the resistance value of which is suitably adjusted. Therefore, the mechanism possibly associated with the bar 5 is not subjected to any stress.

Le pivotement de la barre 5 au moyen de l'outil A ou au moyen d'un mécanisme associé nécessite obligatoirement un effort supérieur et antagoniste à celui des paliers 6 et 7 quel que soit le sens dans lequel on agit mais, en revanche, un moyen de blocage supplémentaire n'est pas indispensable.The pivoting of the bar 5 by means of the tool A or by means of an associated mechanism necessarily requires a greater and antagonistic force than that of the bearings 6 and 7 whatever the direction in which one acts but, on the other hand, a additional locking means is not essential.

Il est possible d'incliner la toile, soit en l'abaissant soit en la relevant, en agissant sur la barre de charge à laquelle les bras articulés 1 et 2 sont reliés car ceux-ci constituent un important bras de levier et agissent sur la barre 5 puisque les supports 3 et 4 sont engagés sur la barre 5 par des passages de même section non circulaire.It is possible to tilt the canvas, either by lowering it or by raising it, by acting on the load bar to which the articulated arms 1 and 2 are connected because these constitute an important lever arm and act on the bar 5 since the supports 3 and 4 are engaged on the bar 5 by passages of the same non-circular section.

Les paliers à friction 6 et 7 sont fixés à la façade par tous moyens connus et de préférence réglables pour compenser les irrégularités de cette façade ou les imperfections du montage.The friction bearings 6 and 7 are fixed to the facade by any known means and preferably adjustable to compensate for the irregularities of this facade or the imperfections of the assembly.

Selon la présente invention, la barre 5 constitue un véritable accouplement à la fois des bras 1 et 2 et des paliers 6 et 7, de telle manière que lorsque l'on agit sur la barre de charge ou sur un dispositif accessoire 8 - 9, on utilise les bras (ou l'outil A) à la manière d'un bras de levier pour déplacer tout l'attelage bras 1 et 2 - barre 5 - paliers 6-7 et cela sans limitation angulaire, contrairement à ce qui se passe, notamment, avec le dispositif décrit dans le brevet français 2.127.434 dont le débattement angulaire est lié au fonctionnement de la barre de torsion.According to the present invention, the bar 5 constitutes a real coupling both arms 1 and 2 and bearings 6 and 7, so that when acting on the load bar or on an accessory device 8 - 9, the arms (or tool A) are used in the manner of a lever arm to move the entire coupling arm 1 and 2 - bar 5 - bearings 6-7 and this without angular limitation, contrary to what happens, in particular, with the device described in the French patent 2,127,434 whose angular movement is linked to the operation of the torsion bar.

Avec un dispositif conforme à l'invention, il est possible de modifier l'inclinaison de la banne en ne desserant qu'un seul des deux paliers 6 et 7 car on divise alors la résistance au pivotement par deux, sans pour autant changer la puissance que l'on développe, grâce au bras de levier, soit des bras 1 et 2,soit de l'outil A.With a device according to the invention, it is possible to modify the inclination of the awning by loosening only one of the two bearings 6 and 7 because the pivoting resistance is then divided by two, without changing the power that we develop, thanks to the lever arm, either arms 1 and 2, or tool A.

L'invention n'est pas limitée aux seuls modes de réalisation décrit et représentés mais en embrasse au contraire toutes les variantes.The invention is not limited to the embodiments described and shown but on the contrary embraces all variants.
