Description
Dispositif auxiliaire de manoeuvre pour portes à commande électrique.Auxiliary operating device for electrically operated doors.
L'invention concerne un dispositif auxiliaire de manoeuvre pour portes à commande électrique, et notamment pour portes susceptibles d'être remontées au moyen de sangles coulissantes. The invention relates to an auxiliary operating device for electrically operated doors, and in particular for doors capable of being reassembled by means of sliding straps.
Dans ce type de portes, par exemple n toile, des sangles verticales fixées à une traverse du bas de la porte s'enroulent sur des tambours entraînés par un groupe motoréducteur électrique. Par mesure de sécurité, en arrière du moteur est prévu un frein qui reste collé en l'absence de courant, de façon à maintenir la porte ouverte, ou à éviter qu'elle ne se ferme en cas de coupure accidentelle du courant pendant son fonctionnement. En arrière du frein est en général prévu un mécanisme de manoeuvre, à chaîne ou à manivelle par exemple, pour permettre de manoeuvrer la porte en cas de panne électrique. Usuellement, la commande manuelle de ce mécanisme doit vaincre l'effort du frein pendant tout le temps de la manoeuvre d'ouverture ou de fermeture de la porte. In this type of door, for example a canvas, vertical straps fixed to a crosspiece at the bottom of the door are wound on drums driven by an electric gearmotor group. As a safety measure, a brake is provided behind the motor which remains stuck in the absence of current, so as to keep the door open, or to prevent it from closing in the event of accidental interruption of the current during operation. . Behind the brake is generally provided an operating mechanism, chain or crank for example, to allow to operate the door in case of electrical failure. Usually, the manual control of this mechanism must overcome the force of the brake during the entire time of the opening or closing operation of the door.
Par ailleurs, il est habituellement prévu une interdiction automatique de toute commande électrique de la porte pendant la manoeuvre pour éviter les accidents. Furthermore, there is usually an automatic prohibition of any electrical control of the door during the maneuver to avoid accidents.
L'un des buts de l'invention est de proposer un dispositif auxiliaire de manoeuvre pour portes à commande électrique qui ne demande qu'un effort minime pour la commande manuelle de la porte en supprimant l'effet du frein pendant la manoeuvre. Un autre but de l'invention est de proposer un tel dispositif qui ne soit pas dangereux en cas de reprise de la commande électrique en cours de commande manuelle, et qui par conséquent ne nécessite pas de sécurité électrique particulière. One of the objects of the invention is to propose an auxiliary operating device for electrically controlled doors which requires only a minimal effort for manual control of the door while eliminating the effect of the brake during the maneuver. Another object of the invention is to provide such a device which is not dangerous in the event of resumption of the electrical control during manual control, and which therefore does not require any particular electrical safety.
L'invention a pour objet un dispositif auxiliaire de manoeuvre pour portes à commande électrique, entrainées par un moteur muni d'un disque portant une garniture coopérant avec un frein fixe, la commande de dispositif se faisant par chaîne et poulie, caractérisé en ce qu'il comporte : un corps cylindrique tourillonnant sur l'arbre du moteur et déplaçable axialement sur cet arbre, présentant une face avant susceptible de coopérer avec la garniture du disque, et portant sur sa face arrière une rampe incurvée susceptible de coopérer avec un galet porté par la poulie, de telle sorte que la rotation de la poulie entraîne, par l'intermédiaire du déplacement du galet sur la rampe, un déplacement axial du corps et sa coopération avec la garniture du disque. The invention relates to an auxiliary operating device for electrically operated doors, driven by a motor fitted with a disc carrying a lining cooperating with a fixed brake, the device being controlled by chain and pulley, characterized in that 'It comprises: a cylindrical body swiveling on the motor shaft and axially displaceable on this shaft, having a front face capable of cooperating with the lining of the disc, and carrying on its rear face a curved ramp capable of cooperating with a worn roller by the pulley, so that the rotation of the pulley causes, by means of the displacement of the roller on the ramp, an axial displacement of the body and its cooperation with the lining of the disc.
Selon d'autres caractéristiques de l'invention
-lors du déplacement axial du corps appui de la garniture se transfère progressivement du frein au corps et inversement.According to other features of the invention
during the axial displacement of the support body of the lining is gradually transferred from the brake to the body and vice versa.
D'autres caractéristiques ressortent de la description qui suit faite avec référence au dessin annexé sur lequel on peut voir
Figure 1 - une vue en coupe axiale partielle d'un mode de réalisation d'un dispositif auxiliaire de manoeuvre pour porte à commande électrique.Other characteristics appear from the following description made with reference to the attached drawing on which one can see
Figure 1 - a partial axial sectional view of an embodiment of an auxiliary operating device for an electrically operated door.
Figure 2 - une vue perspective d'une rampe incurvée du dispositif de la figure 1. Figure 2 - a perspective view of a curved ramp of the device of Figure 1.
En se reportant. à la figure 1, on voit l'arbre 1 du moteur 2, qui doit entraîner les tambours de remontée des sangles d'une porte, par exemple, par l'intermédiaire d'un réducteur non représenté. By referring. in Figure 1, we see the shaft 1 of the motor 2, which must drive the lifting drums of the straps of a door, for example, via a reducer not shown.
Ce moteur 2 est symbolisé par son rotor seulement. This motor 2 is symbolized by its rotor only.
En arrière du moteur est prévu un disque 3 portant sur sa face arrière une garniture d'embrayage 4. Le disque 3 est susceptible d'être attiré vers le moteur par une bobine 5 lorsque le courant passe dans le moteur. Le disque 3 est en permanence sollicité vers l'arrière par un ressort 6. Lorsque le moteur est arrêté, la garniture 4 du disque 3 est appli quée sur un frein annulaire 7. Ce frein est porté par le carter 8 du dispositif auxiliaire de manoeuvre de la porte.At the rear of the engine is provided a disc 3 carrying on its rear face a clutch lining 4. The disc 3 can be attracted towards the engine by a coil 5 when the current flows in the engine. The disc 3 is permanently biased towards the rear by a spring 6. When the engine is stopped, the lining 4 of the disc 3 is applied to an annular brake 7. This brake is carried by the casing 8 of the auxiliary operating device. Door.
En arrière du frein 7 se trouve un corps cylindrique 9, tourillonnant sur l'arbre 1 et susceptible de se déplacer longitudinalement sur cet axe. Ce corps 9 est sollicité en permanence vers l'arrière par des ressorts 10 prenant appui sur la face arrière du frein 7. Il est également susceptible d'être sollicité vers l'avant par l'intermédiaire d'un galet il agissant sur une rampe incurvée 12 solidaire du corps 9. Behind the brake 7 is a cylindrical body 9, swiveling on the shaft 1 and capable of moving longitudinally on this axis. This body 9 is permanently biased towards the rear by springs 10 bearing on the rear face of the brake 7. It is also likely to be biased toward the front by means of a roller, acting on a ramp. curved 12 secured to the body 9.
Cette rampe, représentée sur la figure 2, est ménagée sur une face d'un anneau 13 collé ou fixé dans le corps 9. Elle présente un creux 14 dans lequel se trouve le galet 11 lorsque le dispositif est au repos. La rampe 12 peut etre symétrique par rapport à un plan passant par son ace, et recevoir alors deux galets disposés symétriquement par rapport à cet axe. This ramp, shown in Figure 2, is formed on one side of a ring 13 glued or fixed in the body 9. It has a recess 14 in which is the roller 11 when the device is at rest. The ramp 12 can be symmetrical relative to a plane passing through its ace, and then receive two rollers arranged symmetrically with respect to this axis.
La face avant 17 du corps 9 se comporte comme un disque d'embrayage, susceptible de coopérer avec la garniture 4 lorsque le corps 9 est sollicité vers l'avant. The front face 17 of the body 9 behaves like a clutch disc, capable of cooperating with the lining 4 when the body 9 is biased forward.
En arrière du corps 9 est prévue une poulie 15 commandée manuellement par l'intermédiaire d'une chaîne non représentée. Cette poulie porte sur sa face avant un ou deux supports tels que 16 portant chacun un pivot dirigé radiale ment vers l'axe de rotation de l'arbre 1. Chaque pivot porte un galet 11 susceptible de rouler sur la rampe 12. Behind the body 9 is provided a pulley 15 controlled manually by means of a chain not shown. This pulley carries on its front face one or two supports such as 16 each carrying a pivot directed radially towards the axis of rotation of the shaft 1. Each pivot carries a roller 11 capable of rolling on the ramp 12.
Lorsque le dispositif de manoeuvre est au repos, le galet il est dans le creux 14 de la rampe 12 ; le corps 9 sollicité par les ressorts 10 est en position extrème arrière; la face avant 17 du corps 3 n'est pas appliquée sur la garniture 4 ; la garniture 4 est en appui sur le frein.7 car le ressort 6 repousse le disque 3 vers l'arrière. Aucun courant ne passe dans la bobine 5, le moteur ne tourne pas, et la porte est bloquée en position, haute ou basse, par le frein 7
Si la commande électrique est déclenchée, la bobine 5 attire le disque 3, la garniture 4 quitte le frein et la porte est commandée électriquement sans que le dispositif de manoeuvre soit sollicité en rotation.When the operating device is at rest, the roller is in the recess 14 of the ramp 12; the body 9 biased by the springs 10 is in the rear extreme position; the front face 17 of the body 3 is not applied to the lining 4; the lining 4 is supported on the brake. 7 because the spring 6 pushes the disc 3 backwards. No current flows through the coil 5, the motor does not turn, and the door is locked in position, high or low, by the brake 7
If the electric control is triggered, the coil 5 attracts the disc 3, the lining 4 leaves the brake and the door is electrically controlled without the operating device being biased in rotation.
En cas de panne de courant par exemple, il faut ouvrir ou fermer la porte à la main. Il suffit alors de tirer la chaîne pour faire tourner la poulie 15 dans le sens de la montée ou de la descente. Lorsque la poulie 15 commence à tourner, le galet il roule sur la rampe 12. Comme la position axiale du galet 11 est fixe, c'est le corps 9 qui est repoussé vers l'avant, en comprimant les ressorts 10. La face avant 17 du corps 9 vient s'appliquer sur la garniture 4 qui est toujours en appui sur le frein 7. Lorsque le corps 9 continue d'avancer, l'appui de la garniture 4 se transfère du frein 7 au corps 9, progresstivement. Lorsque la garniture 4 a quitté le frein 7 (cas de la# figure 1) le disque 3 arrive en butée en comprimant le ressort 6 et le galet 11 ne peut plus rouler sur la rampe 12.Si l'on continue à tirer sur la chaîne, la rotation de la poulie se transmet au corps 9 par l'intermédiaire du galet 11 et de la rampe 12, puis au disque 3 par l'intermédiaire de la garniture 4, et de là à l'arbre 1 pour la manoeuvre de la porte. In the event of a power failure, for example, the door must be opened or closed by hand. It then suffices to pull the chain to rotate the pulley 15 in the upward or downward direction. When the pulley 15 begins to rotate, the roller rolls on the ramp 12. As the axial position of the roller 11 is fixed, it is the body 9 which is pushed forward, compressing the springs 10. The front face 17 of the body 9 is applied to the lining 4 which is still resting on the brake 7. When the body 9 continues to advance, the support of the lining 4 is transferred from the brake 7 to the body 9, progressively. When the lining 4 has left the brake 7 (case of # Figure 1) the disc 3 comes into abutment by compressing the spring 6 and the roller 11 can no longer roll on the ramp 12. If one continues to pull on the chain, the rotation of the pulley is transmitted to the body 9 via the roller 11 and the ramp 12, then to the disc 3 via the lining 4, and from there to the shaft 1 for the operation of the door.
Si on relâche la chaîne, alors le ressort 6 repousse le disque 3 et les ressorts 10 le corps 9, la garniture 4 transfère progressivement son appui du corps 9 au frein 7 et la porte reste bloquée. If the chain is released, then the spring 6 pushes the disc 3 and the springs 10 the body 9, the lining 4 gradually transfers its support from the body 9 to the brake 7 and the door remains blocked.
Si maintenant la panne de courant cesse pendant la manoeuvre, par exemple d'ouverture, le moteur va se mettre en marche pour une ouverture sur commande électrique : il va donc se mettre à tourner dans le sens qui est déjà celui de l'arbre 1. Il va donc entraîner le disque 3 plus vite que la chaîne. Le corps 9 va donc tourner lui aussi plus rapidement, la rampe 12 va rouler sous le galet 11 et celui-ci va avoir tendance à se retrouver dans le creux 14 de la rampe, car les ressorts 10 vont faire reculer le corps 9 qui va se désolidariser de la garniture 4. L'opérateur va sentir que la chaîne se détend, mais il ne risquera pas un coup de fouet. Le dispositif selon l'invention est simple et d'une grande sécurité. If now the power failure stops during the maneuver, for example of opening, the engine will start for an opening on electrical command: it will therefore start to turn in the direction which is already that of the shaft 1 It will therefore drive disc 3 faster than the chain. The body 9 will therefore also rotate more quickly, the ramp 12 will roll under the roller 11 and the latter will tend to be found in the hollow 14 of the ramp, because the springs 10 will cause the body 9 which will move back detach from the lining 4. The operator will feel that the chain is slackening, but he will not risk a whiplash. The device according to the invention is simple and very safe.
