Description

La présente invention a trait aux dispositifs d'enroulement de fermeture du genre des stores et similaires, dans lesquels le mécanisme d'entraînement et l'ensemble de ses accessoires sont directement logés à l'intérieur du tambour destiné à la manoeuvre de la toile ou autre tablier souple (FR-A- 2304764).The present invention relates to closing winding devices of the kind of blinds and the like, in which the drive mechanism and all of its accessories are directly housed inside the drum intended for operating the fabric or other flexible apron (FR-A- 2304764).

On sait que la construction des dispositifs de ce genre est compliquée par le fait que le tambour doit être rendu angulairement solidaire de l'arbre de sortie du réducteur de vitesse associé au moteur électrique d'entraînement. Une solidarisation angulaire doit également être opérée entre le tambour et les organes mobiles du mécanisme de fins de courses assurant la commande automatique du moteur précité dans les deux sens de manoeuvre. Ces solidarisations font généralement appel à des poulies ou roues qui sont fixées au tambour à l'aide de vis radiales dont la mise en place est relativement délicate et complique de ce fait les opérations de montage en en renchérissant le coût.It is known that the construction of devices of this kind is complicated by the fact that the drum must be made angularly integral with the output shaft of the speed reducer associated with the electric drive motor. An angular connection must also be made between the drum and the movable members of the limit switch mechanism ensuring the automatic control of the aforementioned motor in both directions of operation. These attachments generally use pulleys or wheels which are fixed to the drum using radial screws, the installation of which is relatively delicate and therefore complicates the mounting operations by increasing the cost thereof.

C'est à ces inconvénients qu'entend principalement remédier la présente invention, laquelle consiste essentiellement à faire comporter à la paroi intérieure du tambour de manoeuvre une série de rainures longitudinales régulières qui coopèrent d'une part avec une pièce à périphérie conjuguée calée sur l'arbre de sortie du réducteur, d'autre part avec deux pignons formant écrous baladeurs pour le mécanisme de fins de course.It is to these drawbacks that the present invention mainly intends to remedy, which consists essentially in making the inner wall of the drive drum comprise a series of regular longitudinal grooves which cooperate on the one hand with a part with a conjugated periphery wedged on the 'reducer output shaft, on the other hand with two pinions forming sliding nuts for the limit switch mechanism.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caratéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 1 est une coupe axiale schématique d'un dispositif d'enroulement de fermeture du type store, établi conformément à la présente invention.Fig. 1 is a schematic axial section of a blind-type closing winding device, established in accordance with the present invention.

Fig. 2 et 3 sont des coupes transversales suivant les plans indiqués en II-II et III-III en fig. 1.Fig. 2 and 3 are cross sections along the planes indicated in II-II and III-III in fig. 1.

A la façon en soi connue, le dispositif représenté comprend deux équerres d'extrémités 1 et 2 destinées à être fixées, le plus souvent à l'aide de vis, dans les parois latérales de l'embrasure qui entoure la fenêtre ou autre ouverture considérée du local. L'équerre 1 est solidaire d'un bâti axial 3 sur l'extrémité libre duquel est emmanché un boîtier 4 renfermant le moteur électrique d'entraînement 5 et le réducteur de vitesse 6 qui lui est associé.In the manner known per se, the device shown comprises two end brackets 1 and 2 intended to be fixed, most often by means of screws, in the side walls of the doorway which surrounds the window or other considered opening of the room. The bracket 1 is integral with an axial frame 3 on the free end of which is fitted a housing 4 containing the electric drive motor 5 and the speed reducer 6 which is associated with it.

Le bâti 3 est agencé de manière à supporter le mécanisme de fins de course qui assure la commande automatique du moteur 5. Ce mécanisme comprend deux tiges filetées 7 orientées parallèlement l'une à l'autre suivant l'axe dudit bâti ; à chacune de ces tiges 7 est associé un ressort 8 qui assure sa retenue angulaire tout en autorisant sa rotation à l'aide d'un organe moleté de manoeuvre 9, en vue du réglage précis du mécanisme à l'une et à l'autre des deux fins de course de la toile. A l'opposé de l'organe 9, chaque tige 7 supporte un poussoir coulissant 10 qui est soumis à l'action d'un ressort 11 et qui coopère par un prolongement longitudinal 10a avec un contacteur électrique 10b branché sur le circuit d'alimentation du moteur 5.The frame 3 is arranged so as to support the limit switch mechanism which provides automatic control of the motor 5. This mechanism comprises two threaded rods 7 oriented parallel to each other along the axis of said frame; each of these rods 7 is associated with a spring 8 which ensures its angular retention while allowing its rotation using a knurled operating member 9, with a view to precise adjustment of the mechanism to both of the two limit switches of the canvas. Unlike the member 9, each rod 7 supports a sliding plunger 10 which is subjected to the action of a spring 11 and which cooperates by a longitudinal extension 10a with an electrical contactor 10b connected to the supply circuit. motor 5.

A la manière usuelle, le dispositif comprend encore un tambour de manoeuvre 12 destiné à ête rendu solidaire de la toile du store TS en vue d'opérer l'envidement et le dévidement de celle-ci. Conformément à l'invention, ce tambour 12 est prévu cannelé intérieurement, les cannelures 12a s'étendant sur toute la longueur de la paroi dudit tambour.In the usual way, the device also comprises an operating drum 12 intended to be made integral with the fabric of the blind TS in order to operate the emptying and reeling of the latter. According to the invention, this drum 12 is provided internally grooved, the grooves 12a extending over the entire length of the wall of said drum.

Celui-ci est supporté à rotation autour du bâti 3 par le moyen de deux bagues 13 (fig. 2) dont la périphérie est prévue crénelée de façon à coopérer, avec les cannelures 12a du tambour, tandis que son ouverture axiale, prévue à paroi lisse, tourne librement sur une portée cylindrique dudit bâti. Au niveau de l'équerre de fixation 2, l'extrémité du tambour 12 est de la même manière supportée par une bague dentée 14 ici prévue plus longue et montée folle sur un axe 2a de ladite équerre.This is rotatably supported around the frame 3 by means of two rings 13 (fig. 2) whose periphery is provided crenellated so as to cooperate, with the grooves 12a of the drum, while its axial opening, provided on the wall smooth, rotates freely on a cylindrical surface of said frame. At the level of the fixing bracket 2, the end of the drum 12 is in the same way supported by a toothed ring 14 here provided longer and idly mounted on an axis 2a of said bracket.

L'entraînement en rotation du tambour 12 est opéré par le moyen d'une pièce cylindrique 15 qui est clavetée sur l'arbre de sortie 6a du réducteur de vitesse 6 et dont la périphérie est prévue dentée de façon à engrener avec les cannelures 12a dudit tambour.The drum 12 is driven in rotation by means of a cylindrical piece 15 which is keyed onto the output shaft 6a of the speed reducer 6 and whose periphery is provided with teeth so as to mesh with the grooves 12a of said drum.

Pour la commande des poussoirs 10 du mécanisme de fins de course, on a monté sur chaque tige filetée 7 un écrou baladeur formé par un pignon 16 qui, comme montré en fig. 3, engrène directement avec les cannelures 12a du tambour 12. Ces pignons ou écrous 16 se déplacent donc axialement le long des tiges 7 lors de l'entraînement en rotation du tambour 12 et viennent de ce fait actionner alternativement (les filetages des deux tiges étant évidemment prévus opposés) les contacteurs du mécanisme sus-mentionné.For controlling the pushers 10 of the limit switch mechanism, a sliding nut formed by a pinion 16 is mounted on each threaded rod 7 which, as shown in FIG. 3, meshes directly with the grooves 12a of the drum 12. These pinions or nuts 16 therefore move axially along the rods 7 during the rotation drive of the drum 12 and therefore actuate alternately (the threads of the two rods being obviously provided opposite) the contactors of the mechanism mentioned above.

On conçoit les avantages présentés par la structure ci-dessus décrite. Le montage en place du tambour 12 est effectué par coulissement longitudinal préalablement à la fixation de l'équerre latérale 2, les cannelures 12a venant ainsi directement coopérer avec les bagues 13 et 14, les pignons ou écrous baladeurs 16 et la pièce dentée 15. Aucune vis de solidarisation angulaire n'est nécessaire.The advantages presented by the structure described above can be understood. The mounting in place of the drum 12 is carried out by longitudinal sliding prior to the fixing of the lateral bracket 2, the grooves 12a thus coming directly to cooperate with the rings 13 and 14, the sliding gears or nuts 16 and the toothed part 15. None angular fastening screw is not necessary.

Il va de soi que le nombre des bagues 13 et 14 peut varier dans une large mesure, en fonction notamment de la longueur du tambour 12 et de la charge auquel celui-ci est soumis.It goes without saying that the number of rings 13 and 14 can vary to a large extent, depending in particular on the length of the drum 12 and the load to which it is subjected.
