An indicator 11 sliding as a light fit on rods 10 allows the high position of the shutter to be noted.

Description

La présente invention est relative à un dispositif de fin de course utilisé pour Arrêt en position haute et basse d'un rideau à enroulement actionné par un motorbducteur placé au centre du tambour enrouleur.The present invention relates to an end-of-travel device used for stopping in the high and low position of a rolling curtain actuated by a gear motor placed in the center of the winding drum.

Dans les systèmes existants, le réglage du fin de course bas est accessible car le rideau est déroulé, mais il n'en est pas de même pour la fin de course haute dont le réglage ne peut se faire que par approches successives, le rideau interdisant l'accès au mécanisme de réglage.In existing systems, the adjustment of the lower limit switch is accessible because the curtain is unrolled, but it is not the same for the upper limit switch whose adjustment can only be done by successive approaches, the curtain preventing access to the adjustment mechanism.

La présente invention permet de remédier à cet inconvénient majeur: l'invention sera mieux comprise à partir des dessins annexés où: - La figure 1 représente un dispositif de fin de course selon l'art antérieur ; - La figure 2 représente le dispositif antérieur vu en coupe; - La figure 3 représente le dispositif selon l'invention; - La figure 4 représente une coupe du dispositif selon l'invention; - Les figures 5, 6 et 7 représentent des sections du dispositif selon l'invention dans des plans perpendiculaires à l'axe principal.The present invention overcomes this major drawback: the invention will be better understood from the accompanying drawings in which: - Figure 1 shows a limit switch device according to the prior art; - Figure 2 shows the prior device seen in section; - Figure 3 shows the device according to the invention; - Figure 4 shows a section of the device according to the invention; - Figures 5, 6 and 7 show sections of the device according to the invention in planes perpendicular to the main axis.

Selon la technique antérieure, le dispositif de fin de course est actionné à partir d'une couronne intérieure (1) dont la surface externe sert de noyau.According to the prior art, the end-of-travel device is actuated from an inner ring (1) whose outer surface serves as a core.

pour ltenroulement d'un tablier. Cette couronne transmet son mouvement à une tige filetée (2) par l'intermediaire de deux pignons (4, 6), le pignon (6) etant solidaire de la tige filetée (2).for the winding of an apron. This crown transmits its movement to a threaded rod (2) by means of two pinions (4, 6), the pinion (6) being integral with the threaded rod (2).

L'écrou baladeur (8) maintenu en rotation par un index (13) rendu solidaire de ltecrou (8) par un contre-écrou (22) se déplace sur la tige filetée (2).The sliding nut (8) kept in rotation by an index (13) made integral with the nut (8) by a lock nut (22) moves on the threaded rod (2).

Lors de l'enroulement, ltécrou (8) se déplace sur la tige filetée (2) et vient actionner la butée (18) solidaire du poussoir (20), ledit poussoir agissant sur un rupteur électrique (21) inséré sur le circuit d'alimentation électrique du moteur réducteur, provoquant ainsi l'arrêt de l'enroulement.During winding, the nut (8) moves on the threaded rod (2) and actuates the stop (18) integral with the pusher (20), said pusher acting on an electric breaker (21) inserted on the circuit. power supply to the reduction motor, thus causing the winding to stop.

Le réglage d'une position d'arrêt est réalisé en déplaçant ltécrou baladeur (8) sur la tige filetée (2) en neutralisant l'index (13) par déblocage du contreécrou (22).The adjustment of a stop position is carried out by moving the sliding nut (8) on the threaded rod (2) by neutralizing the index finger (13) by unlocking the lock nut (22).

Lorsque la position adéquate est obtenue, le contreécrou (22) est resserré, et rend à nouveau l'index (13) solidaire de l'#crou (8), ledit index (13) interdisant à nouveau la rotation de ltécrou (8). Lorsque le rideau doit être réglé pour sa position basse, le système est alors accessible et le réglage de ltécrou (8) peut être fait de telle sorte qu'il agit sur le rupteur électrique par l'intermédiaire du poussoir (20) solidaire de la butée (18).When the appropriate position is obtained, the lock nut (22) is tightened, and again makes the index (13) integral with the # nut (8), said index (13) again preventing rotation of the nut (8) . When the curtain has to be adjusted for its low position, the system is then accessible and the adjustment of the nut (8) can be made so that it acts on the electrical switch by means of the pusher (20) integral with the stop (18).

Le réglage de la position basse ne présente pas de difficulté particulière.Adjusting the low position presents no particular difficulty.

Pour le réglage-de la position haute, il faut procéder de la même manière, mais par approches successives. Un montage identique est réalisé parallélement avec un ensemble tige filetée - écrou, filetés dans le sens inverse du premier. For the adjustment of the high position, it is necessary to proceed in the same way, but by successive approaches. An identical assembly is carried out in parallel with a threaded rod - nut assembly, threaded in the opposite direction to the first.

Le dispositif selon l'invention permet le réglage en aveugle de la position haute d'un rideau c'est-à-dire lorsque celui-ci est enroulé et recouvre l'ensemble du motoréducteur et de ses moyens de réglage de fin de course.The device according to the invention allows blind adjustment of the upper position of a curtain, that is to say when it is rolled up and covers all of the gearmotor and its end-of-stroke adjustment means.

Le dispositif selon l'invention se compose d'un entraîneur (9) en liaison avec la couronne d'entrainement du rideau, entraîneur qui comporte une denture sur une longueur équivalente au déplacement des écrous baladeurs (14). Les écrous (14) sont tels que l'un possède un filetage à droite et l'autre un filetage à gauche, lesdits écrous (14) comportant tous deux une denture extérieure permettant leur entraînement par la tige cannelée (9).The device according to the invention consists of a trainer (9) in connection with the curtain drive crown, trainer which has toothing over a length equivalent to the movement of the sliding nuts (14). The nuts (14) are such that one has a right-hand thread and the other a left-hand thread, said nuts (14) both having an external toothing enabling them to be driven by the grooved rod (9).

Lors du fonctionnement, les tiges de fin de course sont immobilisees en rotation par le crabot (19) agissant sur les molettes de reglage (17) lesdites molettes comportant une denture venant s'insérer dans la denture du crabot lors de son positionnement par translation selon l'axe longitudinal du dispositif.During operation, the end of travel rods are immobilized in rotation by the dog clutch (19) acting on the adjustment knobs (17), said knobs having a toothing inserted into the toothing of the dog clutch during its positioning by translation along the longitudinal axis of the device.

Ledit crabot (19) est maintenu dans sa position de verrouillage à l'aide d'un ressort (24). Les tiges filetées (16) sont solidaires des molettes de réglage (17) et sont fixes au cours du fonctionnement.Said dog clutch (19) is held in its locked position by means of a spring (24). The threaded rods (16) are integral with the adjustment knobs (17) and are fixed during operation.

En fonctionnement, les écrous (14) se déplacent sur les tiges filetées (16) et viennent agir alternativement sur les butées (15) qui sont solidaires des poussoirs agissant sur deux rupteurs électriques (5) places dans le circuit d'alimentation du motoréducteur.In operation, the nuts (14) move on the threaded rods (16) and act alternately on the stops (15) which are integral with the pushers acting on two electrical switches (5) placed in the power supply circuit of the gearmotor.

Le réglage de la position basse se fait directement sur le système de fin de course rendu accessible lorsque le rideau est déroulé, le réglage consistant à venir placer l'écrou de fin de course bas sur la butée correspondante en libérant par un mouvement transversal le crabot (19) de manière à accéder à la molette de réglage (17), puis à relâcher le crabot (19) qui reprend sa position de verrouillage lorsque ltécrou (14) de bas de course est au contact de la butée (15) qui lui correspond.The adjustment of the low position is done directly on the limit switch system made accessible when the curtain is unrolled, the adjustment consisting in placing the lower limit nut on the corresponding stop by releasing the dog clutch by a transverse movement (19) so as to access the adjustment wheel (17), then to release the dog clutch (19) which returns to its locking position when the nut (14) at the bottom of the stroke is in contact with the stop (15) which matches.

Le réglage précis de la position haute, qui ne peut se faire directement puisque le tablier enroulé interdit l'accès au dispositif de réglage, est obtenu à partir d'un index (11) coulissant avec un léger serrage sur les deux colonnes (10) du bâti, et qui est amené contre ltécrou bas déjà réglé. The precise adjustment of the high position, which cannot be done directly since the rolled up apron prevents access to the adjustment device, is obtained from a sliding index (11) with a slight tightening on the two columns (10) of the frame, and which is brought against the low nut already adjusted.

Ce léger serrage est obtenu par des moyens tels qu'un ressort lame venant en appui sur au moins une des tiges (10).This slight tightening is obtained by means such as a leaf spring coming to bear on at least one of the rods (10).

A l'aide du moteur, on enroule alors le rideau jusqu'à la position haute désirée. Pendant cette manoeuvre, le déplacement de l'index est fonction de la hauteur du rideau. On replace ensuite le rideau en position basse de manière à pouvoir accéder au dispositif de réglage. Using the motor, the curtain is then rolled up to the desired high position. During this maneuver, the movement of the index finger depends on the height of the curtain. The curtain is then replaced in the low position so as to be able to access the adjustment device.

A l'aide du bouton moleta (17) pour le haut de course, on amène recrou (14) de fin de course haute sur la position repérée par l'index qui a conservé sa position. Using the moleta button (17) for the top of the stroke, the upper limit switch (14) is brought to the position indicated by the index which has retained its position.

Pour éviter toute fausse manoeuvre, le capot coiffant le dispositif de fin de course ne peut être remis que losque tous les éléments mobiles sont en position de fonctionnement normal.To avoid any false operation, the cover covering the end-of-travel device can only be put back when all the moving elements are in the normal operating position.

Le dispositif selon l'invention permet d'effectuer en une seule manoeuvre le reglage des fins de course d'un rideau métallique. Le dispositif n'est d'ailleurs pas limite à cette seule application, mais à toutes celles nécessitant le repérage de deux positions devant être reproduites au cours de cycles successifs, tels que des rideaux de théâtre ou de cinéma. The device according to the invention makes it possible to adjust the limit switches of a metal curtain in a single maneuver. The device is also not limited to this single application, but to all those requiring the identification of two positions to be reproduced during successive cycles, such as theater or cinema curtains.
