Abstract

The emergency control intended to allow manual operation of closure in the event of breakdown of the drive motor (2) acts not on the electromagnetic brake (14) but on the annulus gear (18) of the epicyclic reduction gear, this being with the aid of a cable (9) which, by pulling, allows deformation of the elastic pin (24) which angularly retains the said annulus. <IMAGE>

Description

On sait que pour la protection de certains locaux et tout particulièrement des vitrines et entrées des magasins, on a fréquement recours à des dispositifs de fermeture dans lesquels le tablier souple (grille ou lames articulées) destiné à être envidé ou dévidé est associé à des moyens élastiques d'équilibrage qui sont bandés lors de l'abaisssement (fermeture) dudit tablier afin d'assister l'opération inverse de relèvement (ouverture).It is known that for the protection of certain premises and in particular of shop windows and entrances to stores, recourse is frequently had to closing devices in which the flexible apron (grid or articulated blades) intended to be unloaded or unreeled is associated with means balancing elastics which are bandaged during the lowering (closing) of said deck in order to assist the reverse lifting operation (opening).

L'agencement général d'un tel dispositif ressort de l'examen de la fig. 1 du dessin annexé aux présentes. Le tablier souple 1, dont les bords coopèrent avec des guides verticaux 2 fixés de part et d'autre de l'ouverture à protéger, est rendu solidaire par son bord supérieur de deux tambours 3 montés fous sur une poutrelle horizontale 4 supportée par deux platines latérales 5. A l'intérieur de chaque tambour 3 est prévu un ressort spiral dont une extrémité est fixée à la poutrelle 4, tandis que l'extrémité opposée est amarrée à la paroi interne du tambour correspondant. On comprend que chaque ressort est enroulé lors de la descente du tablier 1 et qu'il tend ainsi à entraîner en sens inverse son tambour 3 lorsqu'il s'agit de remonter ledit tablier.The general arrangement of such a device appears from the examination of FIG. 1 of the drawing appended hereto. The flexible deck 1, the edges of which cooperate with vertical guides 2 fixed on either side of the opening to be protected, is made integral by its upper edge with two drums 3 mounted idly on a horizontal beam 4 supported by two plates lateral 5. Inside each drum 3 is provided a spiral spring, one end of which is fixed to the beam 4, while the opposite end is moored to the internal wall of the corresponding drum. It is understood that each spring is wound when the apron 1 descends and that it thus tends to drive its drum 3 in the opposite direction when it is a question of reassembling said apron.

Bien qu'un tel système permette une manoeuvre du tablier à la main, on a proposé de le motoriser en fixant sur la poutrelle 4, entre les deux tambours 3, un moto-réducteur 6. Celui-ci comprend un mécanisme de fins de course 6a destiné à la commande d'un moteur électrique associé à un frein automatique et à un réducteur de vitesse, le plus souvent du type épicycloïdal. L'arbre de sortie de ce moto-réducteur porte un pignon qui coopère avec une denture ménagée à l'intérieur d'un tambour 6b, de sorte qu'il suffit de fixer le bord supérieur du tablier 1 audit tambour pour en assurer la manoeuvre électrique à l'aide d'un commutateur-inverseur du type de celui indiqué en 7.Although such a system allows the deck to be maneuvered by hand, it has been proposed to motorize it by fixing on the beam 4, between the two drums 3, a gear motor 6. This includes a limit switch mechanism 6 is for controlling an electric motor associated with an automatic brake and a speed reducer, usually the planetary kind. The output shaft of this geared motor carries a pinion which cooperates with a toothing formed inside a drum 6b , so that it suffices to fix the upper edge of the apron 1 to said drum to ensure its electrical operation using a reversing switch of the type indicated in 7.

Il y a bien entendu lieu de prévoir une commande de secours propre à permettre de pallier à une avarie du moteur d'entraînement ou à une panne de courant, en permettant la manoeuvre manuelle du tablier en dépit de la présence du frein automatique. Cette commande de secours est ordinaisement opérée à l'aide d'une poignée 8 reliée par un câble 9 à une fourchette agencee pour agir sur la partie mobile du frein et l'éloigner de la partie fixe à l'encontre des moyens élastiques qui tendent à maintenir lesdites parties appliquées l'une contre l'autre.It is of course necessary to provide an emergency control suitable for overcoming a damage to the drive motor or a power failure, by allowing manual operation of the deck despite the presence of the automatic brake. This emergency control is usually operated using a handle 8 connected by a cable 9 to a fork arranged to act on the movable part of the brake and move it away from the fixed part against the elastic means which tend to keep said parts applied against each other.

L'effort à exercer sur la commande 8 est important et par ailleurs la manoeuvre manuelle du tablier 1 est rendue pénible du fait que la couronne 6b reste liée à l'ensemble du mécanisme épicycloïdal de réduction qui doit donc être entraîné en rotation pour le déplacement du tablier.The effort to be exerted on the control 8 is significant and moreover the manual operation of the deck 1 is made painful because the crown 6 b remains linked to the whole of the epicyclic reduction mechanism which must therefore be rotated for the moving the deck.

C'est à cet inconvénient qu'entend remédier la présente invention, laquelle a pour objet le moto-réducteur électrique à réduction épicycloïdale et à frein automatique qui est défini à la revendication 1.It is to this drawback that the present invention intends to remedy, which relates to the electric geared motor with epicyclic reduction and automatic brake which is defined in claim 1.

En fait l'invention consiste essentiellement à faire agir la commande de secours, non plus sur le frein automatique, mais sur la couronne dentée du réducteur épicycloïdal pour la libérer et faire ainsi cesser momentanément la transmission du mouvement au frein automatique lié au moteur électrique d'entraînement.In fact, the invention essentially consists in making the emergency control act, no longer on the automatic brake, but on the ring gear of the planetary gearbox to release it and thus temporarily stop the transmission of movement to the automatic brake linked to the electric motor d 'training.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques 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 vue en perspective indiquant de manière schématique l'implantation d'un moto-réducteur électrique du type visé par la présente invention.Fig. 1 is a perspective view schematically indicating the location of an electric geared motor of the type targeted by the present invention.

Fig. 2 est une coupe axiale partielle montrant à plus grande échelle l'agencement du moto-réducteur suivant l'invention.Fig. 2 is a partial axial section showing on a larger scale the arrangement of the geared motor according to the invention.

Fig. 3 représente, à plus grande échelle encore, la commande de secours du moto-réducteur suivant fig. 2.Fig. 3 shows, on a still larger scale, the emergency control of the gear motor according to FIG. 2.

En fig. 2, on retrouve la poutrelle 4 sur laquelle est fixé le bâti 10 formant support pour l'ensemble du moto-réducteur. Celui-ci comprend une enveloppe cylindrique 11 qui renferme le moteur électrique d'entraînement 12 dont l'arbre 13 est relié, à travers un frein électro-magnétique 14, à un système réducteur du type épicycloïdal représenté en détail en fig. 3.In fig. 2, there is the beam 4 on which is fixed the frame 10 forming a support for the entire gear motor. This comprises a cylindrical casing 11 which encloses the electric drive motor 12 whose shaft 13 is connected, through an electromagnetic brake 14, to a reduction system of the epicyclic type shown in detail in FIG. 3.

Ce système comporte un premier train réducteur comprenant un planétaire 13a directement prévu en bout de l'arbre 13 du moteur 12. Ce planétaire 13a engrène avec des pignons satellites 15 montés fous sur des axes 16 portés par un plateau 17. Ces pignons 15 engrènent eux-mêmes avec la denture intérieure 18a d'une couronne 18 dont on décrira plus loin le montage particulier.This system comprises a first reduction gear comprising a sun gear 13 a directly provided at the end of the shaft 13 of the motor 12. This sun gear 13 has meshes with satellite pinions 15 mounted idly on axes 16 carried by a plate 17. These pinions 15 mesh themselves with the internal toothing 18 a of a crown 18 which will be described below the particular assembly.

Le plateau 17 est calé en bout du pignon planétaire 19 d'un second train réducteur visible en fig. 2. Ce second train comprend des pignons satellites 20 qui coopèrent simultanément avec le planétaire 19 et avec une denture fixe 10b qu'on a supposé directement taillée à l'intérieur du bossage tubulaire 10a du bâti 10 qui soutient l'enveloppe 11. Les axes 21 qui supportent les satellites 20 sont portés par une pièce terminale 22 qui dépasse en avant du bossage 10a et dont l'extrémité libre est conformée à la manière d'un pignon 22a, lequel engrène avec la denture 6c ménagée à l'intérieur du tambour 6b de fig. 1.The plate 17 is wedged at the end of the planetary pinion 19 of a second reduction gear visible in FIG. 2. This second train comprises planet gears 20 which cooperate simultaneously with the sun gear 19 and with a fixed toothing 10 b which is assumed to be cut directly inside the tubular boss 10 a of the frame 10 which supports the casing 11. The axes 21 which support the satellites 20 are carried by an end piece 22 which protrudes in front of the boss 10 a and whose free end is shaped like a pinion 22 a , which meshes with the teeth 6 c formed at inside the drum 6 b of fig. 1.

Revenant à fig. 3, il convient d'observer que la couronne 18 dont la denture 18a coopère avec les satellites 15 du premier train réducteur est montée dans le bossage tubulaire 10a de manière à pouvoir tourner suivant l'axe commun de ladite couronne et dudit bossage. A cet effet, elle comporte un moyeu central 18b monté fou à l'intérieur de l'ouverture 23a d'une bague 23 insérée axialement entre les extrémités en vis-à-vis de l'enveloppe 11 et du bossage 10a qui assure la retenue angulaire de ladite bague.Returning to fig. 3, it should be noted that the crown 18 whose teeth 18a cooperates with the satellites 15 of the first reduction gear is mounted in the tubular boss 10 has to be rotatable along the common axis of said ring and said boss. To this end, it comprises a central hub 18 b mounted idly inside the opening 23 a of a ring 23 inserted axially between the ends facing the casing 11 and the boss 10 a which ensures the angular retention of said ring.

La retenue angulaire de la couronne 18 est opérée à l'aide d'un organe éclipsable ou élastiquement déformable qui, dans l'exemple de réalisation envisagé, est constitué par une épingle 24 dont la boucle est logée dans un berceau 23b de la bague fixe 23. L'un, référencé 24a, des deux brins rectilignes de cette épingle 24 est prévu suffisament long pour dépasser en dehors du profil extérieur du bossage 10a et pour présenter un oeillet terminal 24b traversé par l'extrémité du câble 9, lequel est pourvu d'une butée 9a. La gaine 9b qui entoure ce câble 9 vient porter contre une patte latérale 23c de la bague 23.The angular retention of the crown 18 is effected by means of an eclipsable or elastically deformable member which, in the envisaged exemplary embodiment, consists of a pin 24, the loop of which is housed in a cradle 23b of the ring fixed 23. One, referenced 24 a , of the two rectilinear strands of this pin 24 is provided long enough to protrude outside the external profile of the boss 10 a and to present a terminal eyelet 24 b crossed by the end of the cable 9 , which is provided with a stop 9 a . The sheath 9 b which surrounds this cable 9 comes to bear against a lateral tab 23 c of the ring 23.

La réaction élastique de l'épingle 24 tend à maintenir le brin 24a engagé dans l'une d'une série d'encoches 18c pratiquées dans un rebord annulaire 18d prévu sur la face transversale de la couronne 18 qui est tournée en direction de la bague 23.The elastic reaction of the pin 24 tends to maintain the blade 24 engaged in one of a series of notches 18 c formed in an annular flange 18d provided on the transverse face of the ring 18 which faces towards of the ring 23.

Dans ces conditions, la couronne 18 ne peut tourner sur elle-même, de sorte qu'elle remplit bien sa fonction vis-à-vis des pignons satellites 15 du premier train réducteur, lesdits pignons étant ainsi obligés, par suite de la rotation de l'arbre 13 et du planétaire 13a, de tourner sur eux-mêmes en impartissant au plateau 17 un mouvement lent de rotation. Le second train réducteur 19-20 abaisse encore la vitesse de rotation, si bien que le pignon 22a entraîne correctement le tambour 6b et assure l'actionnement désiré du tablier 1.Under these conditions, the crown 18 cannot rotate on itself, so that it fulfills its function vis-à-vis the planet pinions 15 of the first reduction gear, said pinions thus being forced, as a result of the rotation of the shaft 13 and of the sun gear 13 a , to rotate on themselves by imparting to the plate 17 a slow rotational movement. The second reduction gear 19-20 further lowers the speed of rotation, so that the pinion 22 a correctly drives the drum 6 b and ensures the desired actuation of the deck 1.

Par contre, en cas d'avarie du moteur 12 ou en cas de panne de courant, il suffit à l'utilisateur de manoeuvrer la poignée 8 à la traction. Le câble 9 oblige alors le brin 24a de l'épingle 24 à se déformer à la manière illustrée en tracé interrompu en fig. 3, si bien que ledit brin est extrait de l'encoche 18c dans laquelle il était logé. De ce fait, la couronne 18 est déverrouillée et est en conséquence libre de tourner sur elle-même.On the other hand, in the event of damage to the motor 12 or in the event of a power failure, the user need only operate the handle 8 under traction. The cable 9 then forces the strand 24 a of the pin 24 to deform as illustrated in broken lines in FIG. 3, so that said strand is extracted from the notch 18 c in which it was housed. As a result, the crown 18 is unlocked and is consequently free to rotate on itself.

On conçoit en conséquence que le tambour 6b se trouve alors dissocié de l'arbre 13 dont la retenue angulaire reste élastiquement opérée par le frein 14, si bien que l'utilisateur peut manoeuvrer manuellement le tablier 1, à l'élévation ou à l'abaissement. En effet, par suite de sa liberté angulaire, la couronne dentée 18 peut être entraînée en rotation par les satellites 15 qui roulent alors sur le pignon planétaire 13a sans entraîner celui-ci.It is therefore understandable that the drum 6b is then dissociated from the shaft 13, the angular retention of which remains elastically operated by the brake 14, so that the user can manually operate the deck 1, at the elevation or at the 'lowering. Indeed, as a result of its angular freedom, the ring gear 18 can be rotated by the satellites 15 which then roll on the planetary pinion 13 a without driving it.

Dès que l'utilisateur actionne la poignée de commande 8 en sens inverse, c'est-à-dire en relâchant le câble 9, le brin 24a de l'épingle 24 vient à nouveau affecter, par élasticité, son orientation initiale pour laquelle il assure, par engagement dans l'une des encoches 18c, la solidarisation angulaire de la couronne 18 et de la bague fixe 23. Le moto-réducteur est ainsi apte à fonctionner à nouveau.As soon as the user actuates the control handle 8 in the opposite direction, that is to say by releasing the cable 9, the strand 24 a of the pin 24 again affects, by elasticity, its initial orientation for which it ensures, by engagement in one of the notches 18 c , the angular securing of the crown 18 and the fixed ring 23. The gear motor is thus able to operate again.

On conçoit que la manoeuvre manuelle de la fermeture autorisée par la commande de secours réalisée conformément à l'invention est considérablement facilitée par rapport aux solutions traditionnelles du fait que cette manoeuvre s'effectue sans que le système réducteur soit entraîné.It is understood that the manual operation of the closure authorized by the emergency control carried out in accordance with the invention is considerably facilitated compared to traditional solutions because this operation is carried out without the reduction system being driven.

Il va de soi qu'on peut envisager d'autres formes de réalisation pour l'organe élastiquement déformable ou autrement éclipsable qui assure la retenue angulaire de la couronne dentée.It goes without saying that other embodiments can be envisaged for the elastically deformable or otherwise eclipsable member which ensures the angular retention of the toothed crown.
