Description

La présente invention est relative à un réducteur avec frein pour la manoeuvre electrique des volets roulants, stores, rideaux de fermeture et similaires.The present invention relates to a reduction gear with brake for the electrical operation of roller shutters, blinds, shutters and the like.

On sait que, pour la manoeuvre électrique des volets roulants et similaires, on utilise un moteur électrique entraînant en rotation, par l'intermédiaire d'un réducteur, un organe tubulaire sur lequel s'enroule le volet. Généralement, le moteur et le train d'engrenages réducteurs sont logés à l'intérieur de cet organe tubulaire.It is known that, for the electrical operation of roller shutters and the like, an electric motor is used which drives in rotation, by means of a reduction gear, a tubular member on which the shutter is wound. Generally, the motor and the reduction gear train are housed inside this tubular member.

On prévoit en outre un système de freinage dont le rôle est d'empêcher toute descente intempestive et d'arrêter à volonté le volet dans toute position.A braking system is also provided, the role of which is to prevent any untimely descent and to stop the shutter at will in any position.

Actuellement, ce freinage est le plus souvent réalisé par un système électromagnétique agissant sur l'axe du moteur.Currently, this braking is most often carried out by an electromagnetic system acting on the axis of the engine.

Un tel système est d'une réalisation délicate. En outre, il ne protège pas l'utilisateur en cas de descente intempestive due à la rupture accidentelle d'un des organes mécaniques fonctionnant à vitesse élevée entre le moteur et les étages basse vitesse du réducteur.Such a system is a delicate achievement. In addition, it does not protect the user in the event of untimely descent due to the accidental rupture of one of the mechanical members operating at high speed between the motor and the low speed stages of the gear unit.

Pour résoudre cette difficulté, la présente invention concerne un réducteur à frein cractérisé en ce qu'on interpose un système de freinage mécanique avant le dernier étage de réduction du réducteur de manière à obtenir un ensemble réducteur-frein intégré et compact.To resolve this difficulty, the present invention relates to a cractérisé brake reducer in that a mechanical braking system is interposed before the last reduction stage of the reducer so as to obtain an integrated and compact reducer-brake assembly.

Selon un mode de réalisation préféré de cette invention, le dispositif de freinage est du type décrit dans le brevet français N° 73 26 489 déposé le 19 Juillet 1973 par le présent titulaire et publié sous le numéro 2 248 742.According to a preferred embodiment of this invention, the braking device is of the type described in French patent No. 73 26 489 filed on July 19, 1973 by the present holder and published under the number 2 248 742.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence au dessin annexé sur lequel :

  • - La figure 1 est une vue en coupe longitudinale du dispositif selon l'invention et,
  • - La figure 2 est une vue en coupe selon II-II de la figure 1.
Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawing in which:
  • FIG. 1 is a view in longitudinal section of the device according to the invention and,
  • - Figure 2 is a sectional view along II-II of Figure 1.

En se référant au dessin, on voit en 11 l'organe tubulaire sur lequel s'enroule le volet roulant ou similaire (non représenté) entraîné par une pièce à encoches telle que 13, elle-même solidaire du réducteur par l'axe 12.Referring to the drawing, we see at 11 the tubular member on which the roller shutter or the like (not shown) is wound, driven by a notched piece such as 13, itself secured to the reducer by the axis 12.

Dans l'élément tubulaire 10 fixé en rotation est logé le système réducteur qui, dans l'exemple de réalisation, est constitué par trois trains épicycloïdaux 14-15-16 entraînés par l'axe 17 du moteur (non représenté).In the tubular element 10 fixed in rotation is housed the reducing system which, in the exemplary embodiment, consists of three planetary gears 14-15-16 driven by the axis 17 of the motor (not shown).

Selon la présente invention, on interpose un dispositif de freinage mécanique désigné dans son ensemble par la référence 18 entre les trains épicycloïdaux 14 et 15 du réducteur.According to the present invention, there is interposed a mechanical braking device designated as a whole by the reference 18 between the planetary gears 14 and 15 of the reduction gear.

Selon un exemple de réalisation préféré, mais non limitatif de cette invention, le dispositif de freinage 18 est du type décrit dans le brevet français N° 73 26 489, mentionné ci-dessus.According to a preferred, but nonlimiting, exemplary embodiment of this invention, the braking device 18 is of the type described in French patent No. 73 26 489, mentioned above.

Ce dispositif de freinage comprend essentiellement un manchon d'entraînement 24 entraîné par le train épicycloïdal 15 et comportant une partie en demi-lune 25 et un manchon 20 solidaire du pignon 12ʹ et comportant lui aussi une partie en demi-lune 22.This braking device essentially comprises a drive sleeve 24 driven by the planetary gear 15 and comprising a half-moon part 25 and a sleeve 20 integral with the pinion 12ʹ and also comprising a half-moon part 22.

Dans la bague 26, immobilisée dans l'organe tubulaire 10, est monté un ressort hélicoïdal 28 qui est concentrique aux parties en demi-lune et qui est conçu et positionné de manière que ses extrémités 30 et 30ʹ soient interposées entre les portées en regard des parties en demi-lune 22 et 25 comme on le voit clairement sur la figure 2.In the ring 26, immobilized in the tubular member 10, is mounted a helical spring 28 which is concentric with the half-moon parts and which is designed and positioned so that its ends 30 and 30ʹ are interposed between the bearing surfaces facing the half-moon parts 22 and 25 as clearly seen in FIG. 2.

Comme décrit dans le brevet français ci-dessus, le ressort hélicoïdal tourne librement dans la bague 26 s'il est sollicité par les portées de la demi-lune 25 entrainée par le moteur par l'intermédiaire des trains épicycloïdaux 15 et 16.As described in the French patent above, the helical spring rotates freely in the ring 26 if it is stressed by the bearing surfaces of the half-moon 25 driven by the motor via the planetary gear trains 15 and 16.

Par contre, il se bloque dans la bague 26 fixé s'il est sollicité par la demi-lune 22 solidaire de l'arbre du volet par l'intermédiaire du train épicycloïdal 14.On the other hand, it is blocked in the ring 26 fixed if it is biased by the half-moon 22 secured to the shaft of the flap via the planetary gear 14.

On voit donc que l'arrêt du moteur dans un sens ou dans l'autre interdit la rotation du manchon 20 et immobilise l'arbre d'enroulement du volet ou similaire.It can therefore be seen that stopping the motor in one direction or the other prohibits rotation of the sleeve 20 and immobilizes the winding shaft of the shutter or the like.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représenté, mais qu'elle en englobe toutes les variantes.It remains to be understood that this invention is not limited to the embodiment described and shown, but that it encompasses all variants thereof.
