Description

Dispositif auto-equilibre de manaeuvre de volet roulant Certains dispositifs de manmuvre de volets rou- lants comportent des moyens d'6quilibrage constitu6s par une roue ä rocket, convenablement serr6e entre deux plateaux solidaires de Farbre Sur lequel s'en- roule 1e volet. Self-balancing roller shutter maneuvering device Some roller shutter maneuvering devices comprise balancing means consisting of a rocket wheel, suitably clamped between two plates integral with the shaft on which the shutter is wound.

A la mont6e, 1e rocket laisse toumer la roue sans effort ; ä la descente, 1e frottement entre la roue ä rocket devenue fixe et les plateaux qui Fen- serrent doit theoriquement servir d'equilibrage. L'in- tensite de ce frottement, c'est-ä-dire de la friction des plateaux Sur la roue ä rocket, est g6n6ralement assuree par des moyens tels qu'ecrou et contre-ecrou disposes en bout d'arbre, dont 1e reglage est assez aleatoire et g6neralement malcommode, taut et si bien que 1e volet roulant est 1e plus souvent mal 6quilibr6. When climbing, the rocket lets the wheel turn effortlessly; on the descent, the friction between the rocket wheel which has become fixed and the plates which clamp it should theoretically act as a balance. The intensity of this friction, that is to say the friction of the plates on the rocket wheel, is generally ensured by means such as a nut and lock nut arranged at the end of the shaft, of which the adjustment is quite random and generally inconvenient, so much so that the roller shutter is most often unbalanced.

En vue de realiser un 6quilibrage automatique et Parfait du volet roulant, la prAente invention a pour objet un dispositif auto-equilibr6 de manceuvre de volet roulant, caract6ris6 par 1e fait que Parbre d'en- roulement du volet Supporte dune Part par un bäti est filete Sur une certaine longueur, et que Sur ce filetage est visse un manchon interieurement filet6, Supporte par 1e bäti et qui, dune Part, forme Pla teau d'equilibrage, et, d'autre Part, est usin6 en vue du montage de la couronne dentee de commande du dispositif, cette couronne etant rendue solidaire dudit manchon en son mouvement de rotation, mais pou- vant coulisser Sur 1e manchon suivant la direction de son axe, une roue folle ä rocket etant disposee entre 1e Plateau du manchon et un autre Plateau solidaire de Farbre et cale Sur lui. With a view to achieving automatic and perfect balancing of the rolling shutter, the subject of the present invention is a self-balancing device for maneuvering the rolling shutter, characterized by the fact that the winding shaft of the shutter Supported on the one hand by a frame is threaded Over a certain length, and that On this thread is screwed an internally threaded sleeve6, Supported by the 1st frame and which, on the one hand, forms a balancing plate, and, on the other hand, is machined with a view to mounting the toothed crown for controlling the device, this crown being made integral with said sleeve in its rotational movement, but able to slide on the first sleeve in the direction of its axis, an idle rocket wheel being placed between the Plateau solidary with Farbre and wedge On him.

Le dessin annexe reprAente, ä titre d'exemple, une coupe longitudinale dune forme d'execution d'un dispositif auto-6quilibre de manoeuvre de volet roulant. The accompanying drawing shows, by way of example, a longitudinal section of an embodiment of a self-balancing roller shutter operating device.

Le bäti 1 Supporte 1'arbre 2 Sur lequel doit s'en- rouler 1e volet roulaüt. Une tige de commande 3, manaeuvree comme ä. 1'ordinaire par 1'utilisateur actionne 1e pignon 4 engrenant avec la couronne 5. The frame 1 supports the shaft 2 on which the roller shutter must wind. A control rod 3, operated as ä. ordinary by the user activates the first pinion 4 meshing with the crown 5.

Cette couronne 5 est mont6e Sur 1e manchon 6 qui Porte un m6plat 7 de telle Sorte quelle lui sofft completement solidaire dans ses mouvements de rota- tion autour de Faxe de 1'arbre 2, mais quelle puisse librement se deplacer Sur une certaine longueur par rapport au manchon 6 dans la direction de cet axe. Ce manchon 6 filete int6rieurement est visse Sur une Partie filet6e 8 de Farbre 2 ; il comporte, comme an 1'a dit, une Partie 9, formant Plateau. This crown 5 is mounted on the first sleeve 6 which carries a flat 7 in such a way that it is completely united in its rotational movements around the axis of the shaft 2, but which can freely move over a certain length in relation to to the sleeve 6 in the direction of this axis. This internally threaded sleeve 6 is screwed onto a threaded part 8 of Farbre 2; it comprises, as 1'ai said, a Part 9, forming Plateau.

Un second Plateau 10 est monte Sur 1'arbre 2 et lui est rendu RTI ID="0001.0269" WI="13" HE="4" LX="1303" LY="1911"> solidaire par un meplat 11. 11 est fix6 en Position par 6crou 12 et contre-ecrou 13, mont6s Sur 1'extr6mit6 filetee 14 de Farbre 2. A second plate 10 is mounted on shaft 2 and returned to it RTI ID="0001.0269" WI="13" HE="4" LX="1303" LY="1911"> secured by a flat 11. 11 is fixed in position by nut 12 and lock nut 13, mounted on the threaded end 14 of shaft 2.

Entre les plateaux 9 et 10 est mont6e, folle, une roue dentee 15 ä rocket 16 port6 par 1e bäti 1. Between the plates 9 and 10 is mounted, crazy, a toothed wheel 15 with rocket 16 carried by the first frame 1.

Les sens de rotation de 1'arbre 2 sont indiqu6s par des fleches : A pour la montee du volet ; B pour sa descente. The directions of rotation of the shaft 2 are indicated by arrows: A for raising the shutter; B for his descent.

Quand, sous Faction du pignon 4, la couronne 5 tourne dans 1e sens de la mont6e A, elle entraine 1e manchon filet6 6, qui se devisse d'abord Sur la Partie filet6e 8 de Farbre 2, puis entraine cet arbre 2 des que 1e manchon 6 vient suffisamment comprimer par son Plateau 9 la roue 15, contre le Plateau 10. When, under the action of the pinion 4, the crown 5 rotates in the first direction of the mont6e A, it drives the first threaded sleeve 6, which is unscrewed first On the threaded Part 6e 8 of the shaft 2, then drives this shaft 2 as soon as the first sleeve 6 compresses wheel 15 by its plate 9 sufficiently against plate 10.

Le rocket 16 laissant cette roue 15 fonctionner dans 1e sens de la mont6e, cette operation s'effectue de fagon toute normale. The rocket 16 leaving this wheel 15 to operate in the first direction of the climb, this operation is carried out in a completely normal way.

Des que Futilisateur cesse d'actionner la tige 3 et tont 1e Systeme qui lui est lie dans 1e sens de la mont6e du volet, 1e poids du volet qui tend ä descen- dre confirme la Pression du manchon 6 et de son Pla teau 9, contre la roue 15, qui par Suite de son rocket 16 ne peut tourner dann 1e sens de la descente, ce qui maintient tout Fensemble fermement en place. As soon as the user stops actuating the rod 3 and all the system which is linked to it in the direction of the ascent of the shutter, the weight of the shutter which tends to descend confirms the pressure of the sleeve 6 and of its plate 9, against the wheel 15, which as a result of its rocket 16 cannot turn in the first direction of descent, which keeps the whole assembly firmly in place.

Lorsque I'utilisateur voulant descendre 1e volet manoeuvre la tige 3 en sens contraire, pour imprimer ä 1'arbre 2 une rotation dann 1e sens de la flecke 2, cette action tend ä visser ldgerement 1e manchon 6 Sur la Partie filet6e 8 de Farbre 2, ce qui diminue la Pression exercee par 1e Plateau 9 sur la roue ä rocket 15 et permet ainsi la rotation de Farbre 2 dans 1e sens B de la descente du volet. When the user wishing to lower the first shutter maneuvers the rod 3 in the opposite direction, to impart to the shaft 2 a rotation in the first direction of the fleck 2, this action tends to screw the first sleeve 6 slightly onto the threaded part 8 of the shaft 2 , which decreases the pressure exerted by the plate 9 on the rocket wheel 15 and thus allows the rotation of the shaft 2 in the direction B of the descent of the flap.

Des que 1'utilisateur cesse de faire tourner la tige 3, 1e poids du volet tend de nouveau ä d6visser 1e manchon 6, ce qui revient ä agir plus 6nergique- ment Sur 1e frein constitu6 par les plateaux 9 et 10 frottant contre la roue 15 bloquee par son rocket 16, ce qui fixe 1e volet en Position. As soon as the user stops rotating the rod 3, the weight of the shutter again tends to unscrew the sleeve 6, which amounts to acting more energetically on the brake constituted by the plates 9 and 10 rubbing against the wheel 15. blocked by its rocket 16, which fixes the 1st shutter in Position.

De meine, si 1e poids du volet tendait ä acc616rer la descente plus que ne 1e & sire Futilisateur, 1e meine dispositif fonctionnerait identiquement et automati- quement de teile sorte que 1e dispositif & crit consti- tue bien un Systeme d'auto-6quilibrage Parfait du volet roulant. Likewise, if the weight of the flap tended to accelerate the descent more than the user does, the same device would operate identically and automatically, so that the device actually constitutes a Perfect Self-Balancing System. of the roller shutter.

L'action du dispositif est pratiquement instan- tan6e dans un sens comme dann lautre et 1'utilisa- teur qui ne pergoit aucune anomalie dans la mont6e du volet a, ä la descente, 1'impression d'un 6quili- brage Parfait. Ort remarquera que 1e dispositif ne comporte pas de ressorts de compensation et n'a besoin d'aucun r6glage quel qu'il soit. Toute usure est automatique- ment rattrapde ; elle ne saurait d'ailleurs eire que tres faible, 6tant donn6 qu'il n'y a jamais d'autre frottement que 1e strict necessaire pour desolidariser les plateaux 9 et 10 de la roue ä rocket 15, la descente du volet s'effectuant des que 1e frottement des plateaux 9 et 10 Sur la roue 15 devient trop faible pour bioquer cette descente. The action of the device is practically instantaneous in one direction as in the other and the user who does not perceive any anomaly in the raising of the shutter has, on lowering, the impression of a Perfect balance. Ort will note that the device has no compensating springs and needs no adjustment whatsoever. Any wear is automatically taken up; moreover, it can only be very weak, given that there is never any friction other than what is strictly necessary to separate the plates 9 and 10 from the rocket wheel 15, the shutter lowering taking place as soon as the first friction of the plates 9 and 10 on the wheel 15 becomes too weak to bioquer this descent.
