Description

MECANISME DE TENSION D'UN RESSORT DE COMPENSATION POUR INSTALLATION DE FERMETURE OU DE PROTECTION SOLAIRE COMPENSATION SPRING TENSION MECHANISM FOR CLOSURE OR SUN PROTECTION
L'invention a trait à un mécanisme de manœuvre d'un installation de fermeture ou de protection solaireThe invention relates to a mechanism for operating a closing or sun protection installation.
L'invention a également trait à une installation d fermeture ou de protection solaire incorporant un te mécanisme .The invention also relates to a closing or sun protection installation incorporating a mechanism.
Par installation de fermeture, on entend les portes portails, volets, grilles et matériels équivalents.The term “closing installation” means gate doors, shutters, grilles and equivalent equipment.
Dans une installation de fermeture ou de protectio solaire, un écran, qui peut être un tablier souple ou u panneau rigide ou semi -rigide, est déplacé en regard d'un ouverture afin d'obturer sélectivement celle-ci. Le poid de cet écran exerce sur les moyens d'entraînement un coupl variable, notamment en fonction de la position de ce écran. Il est connu d'utiliser des ressorts dit « d compensation » pour compenser au moins partiellement c couple . Pour qu'une installation fonctionne correctement, i est nécessaire que l'effort de compensation exercé par 1 ressort soit adapté au couple développé par l'écran qu influe sur les moyens d'entraînement. Ce couple es fonction des dimensions de l'écran, de son poids spécifique et de sa position par rapport à l'ouverture. Il est don connu de prévoir des moyens de réglage d'un ressort d* compensation, notamment lors de son armage initial. US-A 4,817,927 enseigne de monter une extrémité d'un ressort d< compensation sur une bague susceptible de tourner autou: d'un axe fixe de l'installation et d'immobiliser cett< bague en rotation par rapport à cet axe grâce à une vit qui, lors du réglage de la tension du ressort, doit êtr desserrée. Ceci impose à l'opérateur d'exercer, lors de c< accidentel et brutal du ressort. Il est donc nécessair l'opérateur de manipuler d'une main un outil permett d'exercer un couple sur la bague et de l'autre main la de blocage, ceci imposant un geste technique particul-ι qui n'est pas nécessairement à la portée d'une personne expérimentée .In a closing or sun protection installation, a screen, which can be a flexible apron or a rigid or semi-rigid panel, is moved opposite an opening in order to selectively close it. The weight of this screen exerts on the drive means a variable coupl, in particular as a function of the position of this screen. It is known to use springs called "compensation d" to at least partially compensate for c torque. For an installation to function properly, it is necessary that the compensation force exerted by 1 spring is adapted to the torque developed by the screen which influences the drive means. This torque is a function of the dimensions of the screen, its specific weight and its position relative to the opening. It is known to provide gift adjustment means of a spring * of compensation, especially during the initial winding. US-A 4,817,927 teaches to mount one end of a compensation spring on a ring capable of turning automatically: on a fixed axis of the installation and to immobilize this <ring rotating in relation to this axis thanks to a lives which, when adjusting the spring tension, must be loosened. This requires the operator to exercise, when c < accidental and brutal spring. It is therefore necessary for the operator to manipulate with one hand a tool allowing to exert a torque on the ring and with the other hand to block it, this imposing a particular technical gesture which is not necessarily to the reach of an experienced person.
Il est également connu, par exemple de US-A- , 981 , ] d'utiliser un système à roue et vis sans fin pour réglage en position d'une bague sur laquelle immobilisée l'extrémité d'un ressort de compensation, tel dispositif est relativement complexe et coûteux.It is also known, for example from US-A-, 981,] to use a wheel and worm system for adjusting the position of a ring on which the end of a compensation spring is immobilized, such a device is relatively complex and expensive.
C'est à ces inconvénients qu'entend p particulièrement remédier l'invention en proposant mécanisme de manœuvre dans lequel la tension d'un ress de compensation peut être réglée de façon aisée et sécurité, au moyen d'un dispositif simple et fiable.It is to these drawbacks that the invention particularly intends to remedy by proposing an operating mechanism in which the tension of a compensating spring can be adjusted easily and safely, by means of a simple and reliable device.
Dans cet esprit, l'invention concerne un mécanisme manœuvre d'une installation de fermeture ou de protect solaire, ce mécanisme étant monté dans ou sur une struct fixe et comprenant un écran d'obturation d'une ouvert ménagé dans cette structure, alors qu'il comprend égaleir au moins un ressort de compensation du poids de cet écr ce ressort étant cinématiquement relié, par l'une de extrémités, avec la structure fixe précitée et, par autre extrémité, avec l'écran précité. Ce mécanisme caractérisé en ce qu'il comprend un disposi d'accouplement unidirectionnel incluant un ressort-fr disposé entre le ressort de compensation et la struct fixe ou entre le ressort de compensation et l'écran, al que des moyens solidaires du ressort de compensation s agencés pour exercer sur le ressort frein un effort blocage de celui-ci par rapport à la structure fixe oi 1 ' écran. Grâce à l'utilisation d'un ressort-frein, on obtd un blocage automatique en rotation de l'extrémité ressort de compensation liée à l'accouplement par rappoi la structure fixe ou à l'écran. Ce blocage est obtenu t qu'il n'y a pas application d'un effort volontaire réglage visant à modifier la position angulaire de ce extrémité, c'est-à-dire à modifier la tension du ressort compensation. L'effort de blocage est à nouveau exercé que cesse l'effort de réglage, à la différence dispositifs connus, par exemple de US-A-4,817,S L'invention procède donc d'une utilisation originale particulièrement avantageuse d'un ressort-frein dont fonctionnement est connu par ailleurs, par exemple de FF 1 425 353, pour d'autres applications. Selon des aspects avantageux mais non obligatoires l'invention, le mécanisme incorpore une ou plusieurs caractéristiques suivantes :In this spirit, the invention relates to a mechanism for operating a closing or sun protection installation, this mechanism being mounted in or on a fixed struct and comprising a screen for closing an open formed in this structure, whereas 'It includes equalizing at least one spring for compensating for the weight of this nut, this spring being kinematically connected, at one end, with the above-mentioned fixed structure and, at the other end, with the above-mentioned screen. This mechanism characterized in that it comprises a unidirectional coupling device including a spring-fr arranged between the compensation spring and the fixed struct or between the compensation spring and the screen, al as means integral with the compensation spring s arranged to exert a locking force on the brake spring with respect to the fixed structure or the screen. Thanks to the use of a brake spring, an automatic blocking in rotation of the compensating spring end linked to the coupling by bringing the fixed structure or to the screen is obtained. This blocking is obtained t that there is no application of a voluntary adjustment force aimed at modifying the angular position of this end, that is to say at modifying the tension of the compensating spring. The locking effort is again exerted that the adjustment effort ceases, unlike known devices, for example from US-A-4,817, S The invention therefore proceeds from a particularly advantageous original use of a spring- brake whose operation is known elsewhere, for example from FF 1 425 353, for other applications. According to advantageous but not compulsory aspects of the invention, the mechanism incorporates one or more of the following characteristics:
Les moyens permettant d'exercer l'effort blocage comprennent une bague disposée, avec possibilité rotation, autour ou partiellement à l'intérieur d élément à section circulaire. La bague peut être pour d'un logement de réception des deux extrémités recourb du ressort-frein. Ce logement est avantageusement pourvu deux surfaces aptes à exercer sur ces extrémités un eff de rapprochement relatif.The means for exerting the locking force comprise a ring arranged, with the possibility of rotation, around or partially inside an element of circular section. The ring can be for a housing for receiving the two curved ends of the brake spring. This housing is advantageously provided with two surfaces capable of exerting on these ends a relative approximation effect.
Il est prévu des moyens de réglage l'intensité de l'effort de blocage. Ces moyens permett de diminuer ou de supprimer l'effort exercé par le ress frein et de libérer ainsi l'une des extrémité du ressort compensation pour permettre le réglage de sa tension. moyens de réglage comprennent avantageusement une ba montée, avec possibilité de rotation, autour d'un élémen section circulaire et pourvue d'une saillie apte à ê frein. On peut, en outre, prévoir que cette bague pourvue de crans ou encoches d'interaction avec un outil commande de sa position angulaire autour de l'éléπ circulaire. Ainsi, l'outil permet d'exercer sur la bague effort de rotation autour de l'élément à sect circulaire, cet effort étant transmis par la saillie l'une ou l'autre des extrémités recourbées du ressc frein, ce qui a pour effet de dilater celui-ci en liber la bague solidaire du ressort de compensation qui p alors tourner dans le sens désiré. En variante, les moy de réglage précités peuvent comprendre un arbre pou d'une saillie radiale apte à être intercalée entre extrémités recourbées du ressort -frein.Means are provided for adjusting the intensity of the blocking force. These means make it possible to reduce or eliminate the force exerted by the brake spring and thus free one of the ends of the compensation spring to allow adjustment of its tension. adjustment means advantageously comprise a mounted ba, with the possibility of rotation, around an element of circular section and provided with a projection capable of being brake. It is also possible to provide for this ring provided with notches or notches for interaction with a tool controlling its angular position around the circular element.

In practice, a first end 31 or 31' a spring 3 or 3 'is wound a surface 51 or 51', a hook being optionally formed to firmly anchor these ends relative to the rings 5 and 5 '.
Au niveau de leurs extrémités respectives opposées, et 32', les ressorts 3 et 3' sont immobilisés sur bagues 6 et 6 ' qui comprennent chacune une surf tronconique 62 ou 62' de réception des extrémités 32 32' .At their respective opposite ends, and 32 ', the springs 3 and 3' are immobilized on rings 6 and 6 'which each include a frustoconical surface 62 or 62' for receiving the ends 32 32 '.
Comme il ressort des figures 2 et 3 , la bague 6 ι pourvue d'une ouverture centrale 61 de forme circulaire dont le diamètre lui permet de tourner autour de l'arbre La surface 62 est étagée pour faciliter la mise en place l'extrémité 32 du ressort 3. La bague 6 comprend égalem< un manchon 63 dans lequel est ménagée une encoche 64 de on note 641 et 642 les bords latéraux et 643 le bord fond.As shown in Figures 2 and 3, the ring 6 ι provided with a central opening 61 of circular shape whose diameter allows it to rotate around the shaft The surface 62 is stepped to facilitate the establishment of the end 32 of the spring 3. The ring 6 also includes a sleeve 63 in which is formed a notch 64 of the side edges 641 and 642 and the bottom edge 643.
Un ressort 7 est disposé autour de l'arbre 4 et l'intérieur du manchon 63. On note 71 et 72 les extrémit du ressort 7 qui est un ressort-frein en ce sens qu'il . apte à freiner la bague 6 par rapport à l'arbre 4, c'est- dire, en pratique, à immobiliser en rotation la bague autour de l'axe X-X' grâce à un effort centripète E.A spring 7 is arranged around the shaft 4 and the inside of the sleeve 63. The ends of the spring 7 are noted 71 and 72 which is a brake spring in that it. able to brake the ring 6 with respect to the shaft 4, that is to say, in practice, to immobilize in rotation the ring around the axis XX 'thanks to a centripetal force E.
Une seconde bague 8 est également montée autour pourvue d'une saillie 81 qui s'étend, par rapport à un c 82 de la bague 8, selon une direction globalement parai] à l'axe X-X'. La saillie 81 a une largeur lui permett d'être insérée entre les extrémités 71 et 72 du ressc frein 7, alors que l'encoche 64 a une largeur permettant de recevoir les extrémités 71 et 72 entre bords 641 et 642.A second ring 8 is also mounted around provided with a projection 81 which extends, relative to a c 82 of the ring 8, in a generally parai direction] to the axis XX '.

Le fonctionnement est le suivant :The operation is as follows:
Par défaut, et en l'absence d'action sur la bague lorsqu'un couple Ci est exercé sur la bague 6 par le resεBy default, and in the absence of action on the ring when a torque Ci is exerted on the ring 6 by the resε
3 du fait de son armage, ce couple Ci a pour effet déplacer le bord 641 de l'encoche 64 jusqu'au contact l'extrémité 71 du ressort 7, le bord 641 exerçant alors l'extrémité 71 un effort F1 dirigé vers le bord 642, ce a pour effet de resserrer le ressort 7 sur l'arbre 4 augmentant l'intensité de l'effort centripète E de bloc du ressort 7 sur l'arbre 4. Le mouvement de la bague 6 ainsi limité par son interaction avec l'extrémité 71.3 due to its winding, this pair Ci has the effect of moving the edge 641 of the notch 64 until contacting the end 71 of the spring 7, the edge 641 then exerting the end 71 a force F 1 directed towards the edge 642, this has the effect of tightening the spring 7 on the shaft 4 increasing the intensity of the centripetal force E of the spring block 7 on the shaft 4. The movement of the ring 6 thus limited by its interaction with the end 71.
Si un couple C2 dirigé en sens inverse par rapport couple Ci est exercé par le ressort 3 sur la bague 6, couple se traduit par un déplacement du bord 642 jusqu contact de l'extrémité 72 du ressort 7 et, co précédemment, par un resserrement de ce ressort sur 1 ' arIf a torque C 2 directed in the opposite direction with respect to the torque Ci is exerted by the spring 3 on the ring 6, this torque results in a displacement of the edge 642 until contact with the end 72 of the spring 7 and, previously, by a tightening of this spring on the rear
4 et par une augmentation de l'effort centripète de bloc E.4 and by an increase in the centripetal force of block E.
Ainsi, le ressort-frein 7 permet d'immobiliser bague 6 sur l'arbre 4, malgré les couples Ci ou C2 trans par le ressort 3.Thus, the brake spring 7 makes it possible to immobilize ring 6 on the shaft 4, despite the couples Ci or C 2 trans by the spring 3.
Il est cependant possible de faire tourner la bagu< autour de l'axe X-X' afin de régler la tension du ress< vers la droite à la figure 3, ceci a pour effet d'amener bord 811 de la saillie 81 jusqu'en contact avec l'extrém 71 du ressort 7, puis d'exercer sur cette extrémité effort F'i opposé à l'effort Fi précédemment mentionné, > effort F'i ayant pour effet de dilater radialement ressort 7 qui relâche alors son effort centripète E , l'arbre 4. Il est ainsi possible d'entraîner en rotatii dans le sens du couple C3, à la fois la bague 8, le ress< 7 et la bague 6, ce qui a pour effet de modifier la tens. du ressort 3.It is however possible to rotate the ring <around the axis XX 'in order to adjust the tension of the spring < to the right in FIG. 3, this has the effect of bringing edge 811 of the projection 81 as far as contact with the end 71 of the spring 7, then exerting on this end the force F'i opposite the force Fi previously mentioned,> effort F'i having the effect of radially expanding spring 7 which then releases its centripetal effort E, the shaft 4. It is thus possible to drive in rotation in the direction of the torque C 3 , both the ring 8, the spring <7 and the ring 6, which has the effect of modifying the tens. of spring 3.
Un réglage en sens inverse peut être obtenu exerçant un couple C4, dirigé en sens inverse du coupe L'effort C4 induit un déplacement du bord opposé 812 de saillie 81 jusqu'au contact de l'extrémité 72, puis déplacement de cette extrémité en direction du bord 641, qui a pour effet de dilater le ressort 7 et de permet! ainsi l'entraînement de la bague 6 dans le sens du couj C4.Adjustment in the opposite direction can be obtained by exerting a torque C 4 , directed in the opposite direction of the cut. The force C 4 induces a displacement of the opposite edge 812 of projection 81 until contact with the end 72, then displacement of this end. towards the edge 641, which has the effect of expanding the spring 7 and allows! thus driving the ring 6 in the direction of the couj C 4 .
Comme représenté à la figure 4, une clé 9 peut et utilisée pour exercer le couple C3 grâce à un effort exercé sur son manche 91. La clé 9 est pourvue d'un nez adapté pour pénétrer dans l'une des rainures 83. Lorsque couple C doit être appliqué, la clé 9 est retournée et effort en sens inverse de l'effort F3 est exercé sur manche 91.As shown in FIG. 4, a key 9 can and used to exert the torque C 3 thanks to a force exerted on its handle 91. The key 9 is provided with a nose adapted to penetrate one of the grooves 83. When torque C must be applied, the key 9 is turned over and effort in the opposite direction to the effort F 3 is exerted on handle 91.
