Description

L'invention concerne un dispositif de réglage angulaire pour bras articulé de tension de la toile d'un store à rouleau ou similaire, le bras articulé comportant de façon connue un élément postérieur monté pivotant autour d'un axe sur une chape appartenant à une pièce formant pivot, montée rotative sur un support de bras fixe.The invention relates to an angular adjustment device for an articulated arm for tensioning the fabric of a roller blind or the like, the articulated arm comprising in a known manner a rear element mounted to pivot about an axis on a yoke belonging to a room. forming a pivot, rotatably mounted on a fixed arm support.

Les stores à rouleau constituant généralement des protections solaires comprennent, assez habituellement, deux ou plusieurs bras de tension. Chaque bras est constitué de deux éléments articulés l'un à l'autre, l'élément postérieur étant aussi articulé à une pièce en forme de chape, liée à un support fixe, tandis que l'élément antérieur est articulé à une barre de charge liée au bord antérieur de la toile. Un ressort, prolongé par un câble de traction, tend à ouvrir l'angle formé par les deux éléments du bras, donc à repousser la barre de charge vers l'avant et, par conséquent, à mettre la toile en tension.Roller blinds generally constituting sun protection, quite usually include two or more tension arms. Each arm consists of two elements articulated to each other, the rear element also being articulated to a piece in the form of a yoke, linked to a fixed support, while the anterior element is articulated to a load bar linked to the front edge of the canvas. A spring, extended by a pulling cable, tends to open the angle formed by the two elements of the arm, thus pushing the load bar forward and, consequently, putting the fabric in tension.

La pièce en forme de chape, à laquelle est articulé l'élément postérieur du bras possède en outre une partie formant un pivot de rotation autour d'un axe horizontal, permettant de l'orienter lors de son montage sur le support fixe, lequel peut être soit une console fixée directement contre un mur ou un plafond, soit un support de bras qui, par l'intermédiaire d'un tube support généralement de section carrée, reprend l'encastrement d'une console fixée à un mur ou un plafond. Ceci autorise un choix initial, et aussi une modification ultérieure éventuelle, de l'orientation du plan dans lequel se déployent les bras et la toile. Ainsi, l'angle d'inclinaison du bras peut être modifié, selon l'inclinaison des rayons du soleil et éventuellement en fonction de l'utilisation du store. Si le store vise aussi à protéger de la pluie, l'angle idéal du bras dépendra également des conditions d'écoulement de l'eau.The yoke-shaped part, to which the rear element of the arm is articulated, furthermore has a part forming a pivot of rotation about a horizontal axis, making it possible to orient it during its mounting on the fixed support, which can be either a console fixed directly against a wall or a ceiling, or an arm support which, by means of a support tube generally of square section, takes up the embedding of a console fixed to a wall or a ceiling. This allows an initial choice, and also a possible subsequent modification, of the orientation of the plane in which the arms and the canvas are deployed. Thus, the angle of inclination of the arm can be modified, depending on the inclination of the sun's rays and possibly depending on the use of the blind. If the awning also aims to protect from the rain, the ideal angle of the arm will also depend on the water flow conditions.

En général, pour le réglage angulaire du bras, on prévoit un axe parallèle au tube d'enroulement de la toile du store, et liant la pièce formant chape au support fixe, ces deux éléments accolés présentant des lumières en arc de cercle centrées sur ledit axe ; un boulon traversant ces lumières permet de bloquer la pièce formant pivot à l'angle désiré, donc de fixer l'inclinaison du bras. On connaît aussi des dispositifs comportant des vis de pression qui permettent de régler l'angle précité avec précision, mais doivent encaisser l'effort du vent, ou encore des dispositifs avec biellette de longueur variable utilisée pour régler et bloquer l'angle considéré. D'autres solutions connues impliquent un cône qui peut être lui aussi équipé de vis de pression pour le réglage.In general, for the angular adjustment of the arm, an axis is provided parallel to the winding tube of the awning fabric, and connecting the piece forming a yoke to the fixed support, these two adjoining elements having lights in an arc centered on said axis; a bolt passing through these lights makes it possible to block the part forming a pivot at the desired angle, therefore to fix the inclination of the arm. There are also known devices comprising pressure screws which make it possible to adjust the aforementioned angle with precision, but must absorb the force of the wind, or else devices with rod of variable length used to adjust and block the angle considered. Other solutions known involve a cone which can also be fitted with pressure screws for adjustment.

D'une façon générale, toutes ces solutions actuelles encaissent mal l'effort dû au vent, et sont longues et incommodes à mettre en place, à régler avec précision et à bloquer efficacement.In general, all of these current solutions do not absorb the effort due to the wind well, and are long and inconvenient to set up, to adjust with precision and to block effectively.

L'invention vise à éliminer tous ces inconvénients, en fournissant un dispositif de réglage d'utilisation aisée et très résistant mécaniquement, particulièrement bien adapté à un bras de store.The invention aims to eliminate all these drawbacks, by providing an easy-to-use and very mechanically resistant adjustment device, particularly well suited to an awning arm.

A cet effet, dans le dispositif de réglage angulaire pour bras articulé de store à rouleau ou similaire selon l'invention, appartenant au genre précisé en introduction, la pièce formant pivot et le support de bras comportent, respectivement, des dentures d'engrenage en prise, l'une intérieure et l'autre extérieure, le nombre de dents de la denture extérieure étant légèrement inférieur au nombre de dents de la denture intérieure tandis qu'un organe de commande possédant une partie excentrée est monté tournant suivant l'axe de l'une des dentures et a sa partie excentrée liée à l'élément comportant l'autre denture, de manière à assurer le maintien en prise des deux dentures tout en permettant le roulement d'une denture relativement à l'autre.To this end, in the angular adjustment device for an articulated arm of a roller blind or the like according to the invention, belonging to the type specified in the introduction, the part forming a pivot and the arm support comprise, respectively, gear teeth in taken, one inside and the other outside, the number of teeth of the external teeth being slightly less than the number of teeth of the internal teeth while a control member having an eccentric part is mounted rotating along the axis of one of the teeth and has its eccentric part linked to the element comprising the other teeth, so as to maintain the engagement of the two teeth while allowing the rolling of one tooth relative to the other.

Selon une forme de réalisation de l'invention, la denture d'engrenage intérieure est formée sur la paroi latérale d'un logement de forme générale cylindrique, ménagé dans le support de bras fixe, tandis que la denture d'engrenage extérieure est formée à la périphérie de la pièce rotative formant pivot, reçue dans le logement, l'organe de commande étant monté tournant dans un alésage percé suivant l'axe du logement précité et ayant sa partie excentrée introduite dans un évidement central de la pièce rotative formant pivot. Avantageusement, l'organe de commande comporte, vers une extrémité, une conformation prévue pour son actionnement au moyen d'un outil, tel qu'une clé d'un type courant.According to one embodiment of the invention, the inner gear teeth are formed on the side wall of a generally cylindrical housing formed in the fixed arm support, while the outer gear teeth are formed at the periphery of the rotary part forming a pivot, received in the housing, the control member being mounted rotating in a bore drilled along the axis of the aforementioned housing and having its eccentric part inserted in a central recess of the rotary part forming a pivot. Advantageously, the control member comprises, towards one end, a conformation provided for its actuation by means of a tool, such as a key of a common type.

Selon une autre forme de réalisation de l'invention, la denture d'engrenage intérieure est formée sur la pièce rotative formant pivot, tandis que la denture d'engrenage extérieure est formée sur le support de bras fixe, ce qui constitue une disposition inverse, et naturellement équivalente, de celle précédemment définie. Dans ce dernier cas notamment, l'organe de commande possédant une partie excentrée peut être monté tournant autour d'un axe qui coïncide avec l'axe de rotation de l'organe d'enroulement de la toile du store, le support fixe qui comporte l'une des dentures d'engrenage constituant aussi un support, du genre console, pour l'ensemble du store.According to another embodiment of the invention, the internal gear teeth are formed on the rotary part forming a pivot, while the external gear teeth are formed on the fixed arm support, which constitutes a reverse arrangement, and naturally equivalent, to that previously defined. In the latter case in particular, the control member having an eccentric part can be mounted rotating about an axis which coincides with the axis of rotation of the winding member of the awning fabric, the fixed support which comprises one of the gear teeth also constituting a support, of the console type, for the entire blind.

Dans tous les cas, le dispositif proposé constitue un mécanisme d'engrenage irréversible, supprimant la nécessité de bloquer fortement l'un des éléments contre l'autre. Le nombre élevé de dents simultanément engrenées, résultant de la faible différence de nombre de dents des deux dentures en prise (l'écart pouvant être de 1,2 ou 3 dents par exemple) rend l'ensemble très résistant. Par principe, ce mécanisme comporte une démultiplication d'effort importante, conduisant à une manoeuvre aisée de l'organe de commande par une seule personne, donc permettant de faire varier facilement l'angle du bras, en soulageant éventuellement le poids du bras par une main de l'opérateur.In all cases, the proposed device constitutes an irreversible gear mechanism, eliminating the need to strongly block one of the elements against the other. The high number of teeth simultaneously meshed, resulting from the small difference in the number of teeth of the two teeth in engagement (the deviation can be 1,2 or 3 teeth for example) makes the whole very resistant. In principle, this mechanism includes a significant reduction in effort, leading to easy operation of the control member by a single person, thus making it possible to easily vary the angle of the arm, possibly relieving the weight of the arm by a operator's hand.

Par ailleurs, dans la configuration préférentielle, les deux dentures d'engrenage se trouvent dissimulées et protégées dans un logement, ce qui procure l'étanchéité souhaitable ainsi qu'un aspect esthétique, l'ensemble étant "fermé" par construction.Furthermore, in the preferred configuration, the two gear teeth are concealed and protected in a housing, which provides the desirable seal and an aesthetic appearance, the assembly being "closed" by construction.

De plus, l'organe de commande du dispositif objet de l'invention peut être accouplé à celui d'au moins un autre dispositif de réglage similaire par l'intermédiaire d'un ensemble d'engrenages, ce qui permet de commander la variation d'inclinaison de tous les bras d'un même store d'une façon simultanée, à partir d'une commande primaire unique et commune. De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, quelques formes d'exécution de ce dispositif de réglage angulaire pour bras articulé de store à rouleau ou similaire :

In addition, the control member of the device which is the subject of the invention can be coupled to that of at least one other similar adjustment device by means of a set of gears, which makes it possible to control the variation d inclination of all the arms of the same blind simultaneously, from a single and common primary control.

Le store auquel s'applique le dispositif de réglage selon l'invention comprend deux bras de tension articulés, dont l'un est visible partiellement sur les figures 1 à 4 (relatives à une première forme de réalisation), où apparaît l'élément postérieur 1 d'un tel bras articulé 2, tandis que l'élément antérieur n'est pas représenté. L'extrémité postérieure de l'élément 1 comporte une chape 3, montée pivotante sur un axe 4 tenu entre les deux branches 5 d'une autre chape, formée sur une pièce rotative 6 formant pivot. La pièce 6 est montée tournante, d'une manière qui sera précisée plus bas, par rapport à un support de bras 7 fixe, lui-même immobilisé sur un tube support 8 horizontal au moyen d'une bride de serrage non représentée.The blind to which the adjustment device according to the invention applies comprises two articulated tension arms, one of which is partially visible in FIGS. 1 to 4 (relating to a first embodiment), where the rear element appears 1 of such an articulated arm 2, while the front element is not shown. The rear end of the element 1 comprises a yoke 3, pivotally mounted on an axis 4 held between the two branches 5 of another yoke, formed on a rotary part 6 forming a pivot. The part 6 is rotatably mounted, in a manner which will be specified below, relative to a fixed arm support 7, itself immobilized on a horizontal support tube 8 by means of a clamp not shown.

Le support de bras 7 possède une embase 9 présentant une encoche 10, en "V" à 90°, venant s'appliquer contre le tube support 8, et un corps 11 présentant un logement 12 de forme générale cylindrique, qui reçoit la pièce rotative 6.The arm support 7 has a base 9 having a notch 10, in a "V" at 90 °, coming to bear against the support tube 8, and a body 11 having a housing 12 of generally cylindrical shape, which receives the rotating part. 6.

Sur la paroi latérale du logement 12 du support de bras 7, il est prévu une denture d'engrenage intérieure 13, comportant un certain nombre N de dents. La pièce rotative 6 de forme générale cylindrique présente, à sa périphérie, une denture d'engrenage extérieure 14, de même module que la denture intérieure 13, mais ayant un nombre de dents légèrement inférieur, par exemple (N-1) ou (N-2) ou (N-3).On the side wall of the housing 12 of the arm support 7, there is provided an internal gear toothing 13, comprising a certain number N of teeth. The rotary part 6 of generally cylindrical shape has, at its periphery, an external gear teeth 14, of the same module as the internal teeth 13, but having a slightly lower number of teeth, for example (N-1) or (N -2) or (N-3).

Le support de bras 7 est percé, suivant l'axe 15 de son logement 12, d'un alésage 16 dans lequel est monté tournant un petit arbre de commande 17, fileté sur une partie de sa longueur. L'arbre 17 comporte une tête cylindrique excentrée 18, introduite dans un évidement central 19 de forme correspondante de la pièce rotative 6, dont l'axe est indiqué en 20.The arm support 7 is pierced, along the axis 15 of its housing 12, with a bore 16 in which is rotatably mounted a small control shaft 17, threaded over part of its length. The shaft 17 comprises an eccentric cylindrical head 18, introduced into a central recess 19 of corresponding shape of the rotary part 6, the axis of which is indicated at 20.

La disposition précédente impose un décalage d entre l'axe 15 du logement 12 et l'axe 20 de la pièce rotative 6 - voir notamment figure 2. Le décalage d est choisi égal à la moitié de la différence des diamètres primitifs des deux dentures d'engrenage 13 et 14. Ainsi, la denture extérieure 14 est toujours maintenue en prise, en un point, avec la denture intérieure 13.The previous arrangement requires an offset d between the axis 15 of the housing 12 and the axis 20 of the rotary part 6 - see in particular Figure 2. The offset d is chosen to be equal to half the difference in the original diameters of the two teeth d gear 13 and 14. Thus, the external toothing 14 is always kept in engagement, at a point, with the internal toothing 13.

En faisant tourner l'arbre de commande 17 autour de l'axe 15, on modifie la position angulaire du point de prise des deux dentures 13 et 14, en faisant rouler la denture extérieure 14 dans la denture intérieure 13 qui est fixe. On modifie ainsi la position angulaire de la denture extérieure 14, donc de la pièce 6 sur laquelle est formée cette denture 14. La position angulaire des branches de chape 5 est ainsi modifiée, et il en est de même pour l'axe de pivotement 4 et, par conséquent, pour le plan dans lequel se déploie le bras articulé 2. Le réglage d'inclinaison du bras 2 est ainsi réalisé, avec un effet démultiplicateur important. Les figures 3 et 4 indiquent, à titre d'exemple, deux positions particulières de réglage angulaire du bras 2.By rotating the control shaft 17 around the axis 15, the angular position of the point of engagement of the two teeth 13 and 14 is modified, by rolling the external teeth 14 in the internal teeth 13 which are fixed. This modifies the angular position of the outer toothing 14, therefore of the part 6 on which this toothing is formed 14. The angular position of the yoke branches 5 is thus modified, and it is the same for the axis pivot 4 and, therefore, for the plane in which the articulated arm is deployed 2. The inclination adjustment of the arm 2 is thus achieved, with a significant multiplier effect. FIGS. 3 and 4 show, by way of example, two particular positions for angular adjustment of the arm 2.

L'arbre de commande 17 peut comporter, à son extrémité éloignée de la tête 18, une conformation 21 permettant son actionnement aisé au moyen d'une clé ou autre outil d'un type courant, par exemple une conformation à "six pans creux". En raison de la faible différence entre les nombres de dents respectifs des deux dentures 13 et 14, le mécanisme est rendu irréversible, et le nombre de dents engrenées simultanément est élevé, également en raison du profil étudié de ces dents, ce qui rend l'ensemble très résistant.The control shaft 17 may comprise, at its end remote from the head 18, a conformation 21 allowing its easy actuation by means of a key or other tool of a common type, for example a conformation with "hexagon socket" . Due to the small difference between the respective numbers of teeth of the two teeth 13 and 14, the mechanism is made irreversible, and the number of teeth meshed simultaneously is high, also due to the studied profile of these teeth, which makes the very resistant set.

Toutefois, comme illustré aux figures 1 et 2, l'axe de commande 17 étant fileté peut recevoir un écrou de blocage 22 garantissant l'application et le maintien de la pièce 6 sur le support 7, dans la position angulaire réglée.However, as illustrated in FIGS. 1 and 2, the control pin 17 being threaded can receive a locking nut 22 guaranteeing the application and the maintenance of the part 6 on the support 7, in the adjusted angular position.

La configuration décrite jusqu'ici, en référence aux figures 1 à 4, permet un réglage angulaire séparé de chaque bras articulé 2. La figure 5 montre une réalisation avec commande commune aux deux bras 2 d'un même store à rouleau, cette figure 5 étant simplifiée en ce sens qu'elle indique l'ensemble du mécanisme d'entraînement mais ne fait pas apparaître tous les éléments de support.The configuration described so far, with reference to FIGS. 1 to 4, allows separate angular adjustment of each articulated arm 2. FIG. 5 shows an embodiment with control common to the two arms 2 of the same roller blind, this FIG. 5 being simplified in that it indicates the entire drive mechanism but does not reveal all the support elements.

Pour chaque bras 2, l'arbre de commande 17 d'un mécanisme tel que décrit ci-dessus est lié en rotation à un pignon extérieur 23. Un arbre rotatif de commande générale 24, monté parallèlement aux deux arbres 17, porte deux pignons 25 en prise, respectivement, avec les deux pignons 23 associés aux mécanismes de réglage des deux bras 2. L'arbre 24 est lui-même pourvu de moyens d'entraînement en rotation, manuels ou motorisés, indiqués très schématiquement en 26. Comme on le comprend aisément, une même ligne d'engrenages peut commander ainsi l'inclinaison de tous les bras d'un même store, quel qu'en soit le nombre, celui-ci n'étant pas limité à deux.For each arm 2, the control shaft 17 of a mechanism as described above is linked in rotation to an external pinion 23. A rotary general control shaft 24, mounted parallel to the two shafts 17, carries two pinions 25 in engagement, respectively, with the two pinions 23 associated with the adjustment mechanisms of the two arms 2. The shaft 24 is itself provided with rotation drive means, manual or motorized, indicated very schematically at 26. As is easily understands, the same line of gears can thus control the inclination of all the arms of the same blind, whatever the number, this being not limited to two.

Les figures 6 à 8, sur lesquelles les éléments correspondant à ceux précédemment décrits sont désignés par les mêmes repères sont relatives à une autre forme de réalisation avec disposition inversée, dans laquelle la denture d'engrenage extérieure 14 est formée sur une pièce fixe 7, tandis que la denture d'engrenage intérieure 13 est formée sur la pièce rotative 6 formant pivot.FIGS. 6 to 8, in which the elements corresponding to those previously described are designated by the same references relate to another embodiment with inverted arrangement, in which the external gear teeth 14 are formed on a fixed part 7, while the internal gear teeth 13 are formed on the rotating part 6 forming a pivot.

Cette pièce rotative 6, comportant la chape 5 sur laquelle est articulé l'élément postérieur 1 du bras 2, est montée tournante autour d'un axe 27 qui constitue aussi l'axe de rotation du tube d'enroulement 28 de la toile du store, tube dont la commande de rotation est réalisable par l'intermédiaire d'une denture 29 et d'un organe d'entraînement 30 également pourvu d'une denture 31.This rotary part 6, comprising the yoke 5 on which the rear element 1 of the arm 2 is articulated, is mounted to rotate about an axis 27 which also constitutes the axis of rotation of the winding tube 28 of the awning fabric, tube the rotation control of which can be achieved by means of a toothing 29 and a drive member 30 also provided with a toothing 31.

L'organe de commande 17 du dispositif de réglage angulaire, comportant une partie excentrée 18, est lui-même monté tournant autour de l'axe 27, la partie excentrée 18 étant introduite dans un évidement correspondant de la pièce fixe 7. Cette dernière, formant une console pouvant être fixée soit à un mur, soit à un plafond 32, soutient l'ensemble du store.The control member 17 of the angular adjustment device, comprising an eccentric part 18, is itself mounted rotating around the axis 27, the eccentric part 18 being inserted in a corresponding recess in the fixed part 7. The latter, forming a console that can be fixed either to a wall or to a ceiling 32, supports the entire blind.

Il est à noter que, dans cette autre forme de réalisation, l'organe de commande 17 (coaxial au tube d'enroulement 28) doit être manoeuvré dans un sens qui est identique au sens de la modification d'inclinaison souhaitée pour le bras 2, ce qui procure une grande commodité d'utilisation. La manoeuvre est réalisée par une conformation à six pans 21, solidaire de la partie excentrée 18 de l'organe de commande 17, l'écrou de blocage 22 étant ici monté sur l'extrémité filetée de l'axe 27.It should be noted that, in this other embodiment, the control member 17 (coaxial with the winding tube 28) must be maneuvered in a direction which is identical to the direction of the desired inclination modification for the arm 2 , which provides great convenience in use. The operation is carried out by a hexagonal conformation 21, integral with the eccentric part 18 of the control member 17, the locking nut 22 here being mounted on the threaded end of the axis 27.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif de réglage angulaire qui ont été décrites ci-dessus, à titre d'exemples ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe. L'invention est aussi applicable à toute installation de protection solaire similaire à un store, mais désignée sous une autre dénomination.It goes without saying that the invention is not limited to the sole embodiments of this angular adjustment device which have been described above, by way of examples; on the contrary, it embraces all of the variant embodiments and applications respecting the same principle. The invention is also applicable to any sun protection installation similar to a blind, but designated under another name.
