- the transmission mechanism is a unidirectional coupling of the freewheel type ensuring the drive of the closing element when climbing.
- This device is furthermore equipped with a manual control making it possible to drive the closing element, in particular to open a shutter in the event of an engine failure, for example during a cut in the electrical supply.
- This manual control comprises a transmission by screw and toothed wheel, that is to say a transmission having a significant reduction.
- Such manual control does not allow rapid opening of the closure element in an emergency.
- Devices of the same kind are also known in which a special breakdown control mechanism is provided. This command also does not allow rapid opening, the weight of the closing element inducing a reduction in the mechanism.

Abstract
Description
L'invention concerne un dispositif de manoeuvre d'un élément de fermeture se déplaçant au moins approximativement verticalement, comprenant un moteur, un réducteur, un arbre d'entraînement de l'élément de fermeture et un mécanisme de transmission entre le réducteur et l'arbre d'entraînement, ce mécanisme de transmission autorisant le débrayage de l'élément de fermeture en descente lorsqu'une force résistante s'oppose à sa descente.The invention relates to a device for operating a closure element moving at least approximately vertically, comprising a motor, a reduction gear, a drive shaft for the closure element and a transmission mechanism between the reduction gear and the drive shaft, this transmission mechanism authorizing the disengagement of the closing element when going down when a resistant force opposes its going down.
Un tel dispositif est connu notamment de la demande de brevet DE 36 08 988. Le mécanisme de transmission est un accouplement unidirectionnel de type roue libre assurant l'entraînement de l'élément de fermeture en montée. Ce dispositif est équipé en outre d'une commande manuelle permettant d'entraîner l'élément de fermeture, en particulier d'ouvrir un volet roulant en cas de panne du moteur, par exemple lors d'une coupure de l'alimentation électrique. Cette commande manuelle comprend une transmission par vis et roue dentée, c'est-à-dire une transmission présentant une démultiplication importante. Une telle commande manuelle ne permet pas une ouverture rapide de l'élément de fermeture en cas d'urgence. On connaît également des dispositifs du même genre dans lesquels il est prévu un mécanisme spécial de commande de dépannage. Cette commande ne permet pas non plus l'ouverture rapide, le poids de l'élément de fermeture induisant une démultiplication dans le mécanisme.Such a device is known in particular from patent application DE 36 08 988. The transmission mechanism is a unidirectional coupling of the freewheel type ensuring the drive of the closing element when climbing. This device is furthermore equipped with a manual control making it possible to drive the closing element, in particular to open a shutter in the event of an engine failure, for example during a cut in the electrical supply. This manual control comprises a transmission by screw and toothed wheel, that is to say a transmission having a significant reduction. Such manual control does not allow rapid opening of the closure element in an emergency. Devices of the same kind are also known in which a special breakdown control mechanism is provided. This command also does not allow rapid opening, the weight of the closing element inducing a reduction in the mechanism.
On connaît par ailleurs des dispositifs d'entraînement équipés d'un frein débrayable et comprenant un ressort de compensation du poids de l'élément de fermeture. Pour permettre une ouverture manuelle rapide de l'élément de fermeture, on a d'abord pensé équiper un tel dispositif d'un mécanisme d'entraînement unidirectionnel. Ceci ne permet toutefois pas de résoudre de façon satisfaisante le problème de la sécurité. En effet, l'arbre d'entraînement étant en général surcompensé pour faciliter la levée de l'élément de fermeture, il n'est plus possible d'assurer sa descente électriquement, la transmission unidirectionnelle étant incapable de fournir à l'élément de fermeture l'effort nécessaire pour. surmonter l'effet de la surcompensationThere are also known drive devices equipped with a disengageable brake and comprising a spring. compensation for the weight of the closure element. To allow rapid manual opening of the closure element, it was first thought to equip such a device with a unidirectional drive mechanism. However, this does not make it possible to satisfactorily resolve the security problem. Indeed, the drive shaft being generally overcompensated to facilitate the lifting of the closure element, it is no longer possible to ensure its descent electrically, the unidirectional transmission being incapable of supplying the closure element the effort required to. overcoming the effect of overcompensation
L'invention a pour but de réaliser, par des moyens simples, un dispositif de manoeuvre d'un élément de fermeture à moteur électrique susceptible d'être ouvert manuellement très rapidement.The object of the invention is to produce, by simple means, a device for operating an electric motor closing element capable of being opened manually very quickly.
Le dispositif selon l'invention est caractérisé en ce qu'il comprend des moyens élastiques de compensation du poids de l'élément de fermeture et en ce que le mécanisme de transmission est au moins constitué d'un accouplement à friction.The device according to the invention is characterized in that it comprises elastic means for compensating for the weight of the closure element and in that the transmission mechanism consists at least of a friction coupling.
Il convient de souligner que le dispositif selon l'invention ne comprend pas de frein, ce qui permet d'éviter le système de débrayage de frein.It should be emphasized that the device according to the invention does not include a brake, which makes it possible to avoid the brake release system.
Un accouplement unidirectionnel peut être associé à l'accouplement à friction de telle sorte qu'en montée, l'entraînement de l'arbre d'entraînement est assuré par le mécanisme d'accouplement unidirectionnel, tandis qu'en descente, l'entraînement est assuré par l'accouplement à friction.A one-way coupling can be combined with the friction coupling so that when going up, the drive of the drive shaft is ensured by the one-way coupling mechanism, while when going down, the drive is ensured by the friction coupling.
La présence d'un accouplement à friction permet d'avoir une compensation moins précise du poids de l'élément de fermeture. L'entraînement est moins sensible aux variations induites par le vieillissement de l'installation, ainsi qu'à l'usure de ses constituants.The presence of a friction coupling makes it possible to have less precise compensation for the weight of the closure element. The drive is less sensitive to the variations induced by the aging of the installation, as well as to the wear of its components.
L'entraînement manuel de l'élément de fermeture peut se faire soit en agissant directement sur cet élément de fermeture, soit, quand cela est possible, en agissant directement sur son arbre d'entraînement.The manual drive of the closure element can be done either by acting directly on this closure element, or, when possible, by acting directly on its drive shaft.
Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.The accompanying drawing shows, by way of example, an embodiment of the invention.
La figure 1 est une vue en coupe axiale d'un dispositif d'entraînement d'un volet roulant.Figure 1 is an axial sectional view of a drive device for a roller shutter.
La figure 2 est une vue en coupe et en demi-coupe selon II-II de la figure 3 du mécanisme de transmission 6 de la figure 1.FIG. 2 is a sectional and half-section view along II-II of FIG. 3 of the
La figure 3 est une vue en demi-coupe axiale, selon III-III de la figure 2 du mécanisme de transmission.Figure 3 is an axial half-section view, along III-III of Figure 2 of the transmission mechanism.
La figure 1 représente un tube d'enroulement 1 de volet roulant monté dans une embrasure de fenêtre 2. Le volet roulant n'a pas été représenté. A son extrémité gauche, le tube d'enroulement 1 est supporté par un roulement 3 supporté lui-même par un moto-réducteur 4 monté à l'intérieur du tube d'enroulement 1 et fixé à l'embrasure 2. A son autre extrémité, le tube d'enroulement 1 est monté rotativement sur un disque 5 fixe en rotation dans l'embrasure 2. Le moto-réducteur 4 entraîne le tube d'enroulement par l'intermédiaire d'un dispositif de transmission 6.FIG. 1 shows a roller shutter winding tube 1 mounted in a
Le tube d'enroulement 1 est en outre solidaire en rotation d'un disque 7 relié au disque fixe 5 par un ressort à boudin 8 travaillant en torsion de manière à compenser le poids du volet roulant lors de son déroulement.The winding tube 1 is also integral in rotation with a
Le dispositif de transmission 6 est représenté aux figures 2 et 3. Il comprend une couronne 9 solidaire en rotation du tube d'enroulement 1 et présentant intérieurement deux encoches opposées 10 et un disque 11 solidaire en rotation de l'arbre de sortie du moto-réducteur 4. Ce disque 11 est muni, de manière connue en soi, de deux cliquets 12 montés respectivement sur un ressort 13 et coopérant avec les encoches 10 de la couronne 9 pour assurer l'entraînement unidirectionnel du tube d'enroulement 1 dans le sens de l'enroulement du volet roulant.The
Le dispositif de transmission 6 comprend en outre un accouplement à friction logé dans la couronne 9. Cet accouplement à friction est constitué d'une paire de rondelles en acier tronconiques 14 et 15 comprimées entre le disque 11 et un flasque fileté 16 vissé dans la couronne 9 de telle sorte qu'il est solidaire en rotation de la couronne 9.The
A la montée, l'enroulement est assuré par l'accouplement unidirectionnel. A la descente, si le volet roulant rencontre un obstacle, le moteur peut continuer de tourner sans entraîner le tube d'enroulement 1 et l'accouplement à friction patine. En descente normale, l'entraînement du tube d'enroulement 1 par le moteur s'effectue par l'accouplement à friction.When climbing, the winding is ensured by the one-way coupling. On the descent, if the roller shutter encounters an obstacle, the motor can continue to run without driving the winding tube 1 and the friction coupling slipping. In normal descent, the winding tube 1 is driven by the motor by the coupling to friction.
En cas de panne électrique, le volet roulant peut être enroulé manuellement en relevant directement le volet roulant. Cette opération est aisée en raison de l'absence de frein et de la compensation du poids du volet roulant.In the event of an electrical failure, the roller shutter can be rolled up manually by raising the roller shutter directly. This operation is easy due to the absence of a brake and the weight compensation of the roller shutter.
Dans une exécution simplifiée, l'accouplement unidirectionnel est supprimé. Dans ce cas, l'accouplement à friction joue aussi bien à la montée qu'à la descente. La sécurité en cas d'obstacle en montée est également assurée, puisque, dans ce cas, l'accouplement à friction peut patiner aussi bien qu'à la descente.In a simplified version, the one-way coupling is eliminated. In this case, the friction coupling plays both up and down. Safety in the event of an uphill obstacle is also ensured, since in this case the friction coupling can slip as well as when descending.
Le dispositif peut être muni d'un verrou activé manuellement ou automatiquement lorsque le volet roulant est fermé de manière à empêcher une ouverture par des personnes non autorisées et d'assurer la sécurité anti-effraction.The device can be fitted with a lock activated manually or automatically when the shutter is closed so as to prevent opening by unauthorized persons and to ensure burglar-resistant security.
Le dispositif selon l'invention est applicable à tous éléments de fermeture se déplaçant verticalement ou obliquement.The device according to the invention is applicable to all closure elements moving vertically or obliquely.
