Description

La présente invention a trait aux dispositifs de fermeture à enroulement électrique, notamment à ceux dans lesquels la manoeuvre de l'organe mobile de fermeture (toile ou autre) est opérée à l'aide d'un moteur électrique porté par un bâti tubulaire monté à l'intérieur même du tambour sur lequel s'enroule ledit organe.The present invention relates to electrically wound closure devices, in particular those in which the operation of the movable closure member (fabric or other) is carried out using an electric motor carried by a tubular frame mounted at the very interior of the drum on which said member is wound.

On sait que dans ce type de dispositifs, il est en pratique indispensable de prévoir la possibilité pour l'utilisateur de manoeuvrer manuellement le tambour à la montée ou à la descente dans le cas où, par suite d'une avarie quelconque ou d'une coupure de courant, la manoeuvre à l'aide du moteur électrique d'entraînement se révélerait impossible. Si dans certaines constructions un tel mécanisme de manoeuvre de secours peut directement agir sur le tambour extérieur d'envidage, dans d'autres au contraire ladite manoeuvre est intégrée au bâti intérieur lui-même qu'il est donc nécessaire de faire tourner pour assurer la rotation du tambour précité.We know that in this type of device, it is in practice essential to provide the possibility for the user to manually maneuver the drum when going up or when going down in the event that, as a result of any damage or power failure, operation using the electric drive motor would be impossible. If in certain constructions such an emergency operating mechanism can directly act on the external drum for emptying, in others, on the contrary, said operating is integrated into the internal frame itself which it is therefore necessary to rotate to ensure the rotation of the aforementioned drum.

Un tel cas a été illustré de manière schématique à la fig. 1 du dessin annexé aux présentes. La référence 1 désigne le tambour d'envidage qui est monté à rotation autour d'un bâti axial 2, lequel renferme l'ensemble des organes du dispositif et en premier lieu le moteur électrique 3 associé d'une part à un mécanisme de frein automatique 4 et d'autre part à un réducteur de vitesse 5 dont l'arbre de sortie porte la roue 6 liée à la paroi interne du tambour 1. A l'opposé de cette roue 6, le bâti 2 est solidaire d'une douille 7 qui est libre de tourner par rapport à une portée cylindrique prévue latéralement sur un carter vertical 8 dans lequel sont logés, outre le dispositif de fins de course (non visible en fig. 1), le système d'entraînement manuel constitué par une roue creuse 9 et une vis sans fin 10, laquelle est entraînée en rotation à l'aide d'un anneau 11 conformé pour coopérer avec une manivelle amovible. L'arbre horizontal qui porte la roue creuse 9 est relié par un mécanisme réducteur épicycloïdal à la douille 7, si bien que lorsque l'anneau 11 est manoeuvré angulairement par l'utilisateur à titre de commande de secours, le bâti 2 est lui-même mis en rotation et, à travers le réducteur 5 prévu irréversible, actionne le tambour 1.Such a case has been illustrated schematically in FIG. 1 of the drawing appended hereto. The reference 1 designates the idling drum which is rotatably mounted around an axial frame 2, which encloses all of the organs of the device and first of all the electric motor 3 associated on the one hand with an automatic brake mechanism 4 and on the other hand to a speed reducer 5 whose output shaft carries the wheel 6 linked to the internal wall of the drum 1. Opposite this wheel 6, the frame 2 is secured to a socket 7 which is free to rotate relative to a cylindrical bearing provided laterally on a vertical casing 8 in which are housed, in addition to the limit switch device (not visible in fig. 1), the manual drive system consisting of a hollow wheel 9 and an endless screw 10, which is rotated by means of a ring 11 shaped to cooperate with a removable crank. The horizontal shaft which carries the hollow wheel 9 is connected by a planetary reduction mechanism to the sleeve 7, so that when the ring 11 is actuated angularly by the user as an emergency control, the frame 2 is itself even put in rotation and, through the reduction gear 5 provided irreversible, actuates the drum 1.

Cette construction est bien connue en pratique et ne nécessite donc pas une description plus détaillée. Il suffit de relever que compte tenu de la rotation du bâti 2 lors de la manoeuvre de secours et du caractère évidemment fixe du carter latéral 8, il est indispensable de prévoir, entre le câble d'alimentation 12 qui pénètre à l'intérieur dudit carter 8 et le condensateur 13 associé au moteur électrique 3, un collecteur rotatif qu'on a schématiquement représenté en 14.This construction is well known in practice and therefore does not require a more detailed description. It suffices to note that taking into account the rotation of the frame 2 during the emergency maneuver and the character obviously fixed to the side casing 8, it is essential to provide, between the power cable 12 which penetrates inside said casing 8 and the capacitor 13 associated with the electric motor 3, a rotary collector which has been schematically represented at 14 .

On a proposé à cet effet différents types de collecteurs rotatifs, mais il convient de souligner que la localisation à l'intérieur de la douille 7 complique les opérations de montage et de branchement. Par ailleurs et surtout, les constructions connues ne comportent pas une fiabilité parfaite, alors que toute avarie implique pour sa réparation des manoeuvres de démontage et de montage compliquées.Various types of rotary manifolds have been proposed for this purpose, but it should be emphasized that the localization inside the socket 7 complicates the mounting and connection operations. Furthermore and above all, the known constructions do not have perfect reliability, while any damage implies for its repair complicated disassembly and assembly operations.

le document français 2506529 montre un contact tournant destiné à transmettre des courants électriques d'une amenée fixe à une partie tournante disposées coaxialement l'une par rapport à l'autre au moyen d'une lamelle de contact fendue à la manière d'une jalousie disposée sur la périphérie coaxialement entre les deux parties.French document 2506529 shows a rotary contact intended to transmit electric currents from a fixed supply to a rotating part arranged coaxially with respect to each other by means of a contact strip split in the manner of a jealousy arranged on the periphery coaxially between the two parts.

C'est à ces inconvénients que la présente invention entend principalement remédier, et ce à l'aide d'un collecteur rotatif de construction nouvelle, spécialement adaptée au problème particulier à résoudre.It is to these drawbacks that the present invention mainly intends to remedy, and this using a rotary collector of new construction, specially adapted to the particular problem to be solved.

Le collecteur rotatif suivant l'invention est essentiellement remarquable en ce qu'il est constitué par deux corps isolants mâle et femelle qui sont propres à s'emboîter l'un à l'intérieur de l'autre et dont les parois tournées en vis-à-vis présentent au moins trois gradins étagés formant appuis pour des disques métalliques annulaires disposés deux par deux et reliés à deux jeux de conducteurs électriques, la connexion entre les disques qui se font face étant opérée à travers au moins une lame cambrée solidaire de l'un des disques de façon à ce qu'une simple poussée axiale exercée sur l'un des deux corps isolants assure la transmission du courant.The rotary collector according to the invention is essentially remarkable in that it consists of two male and female insulating bodies which are capable of fitting one inside the other and whose walls facing each other. opposite have at least three stepped steps forming supports for annular metal discs arranged two by two and connected to two sets of electrical conductors, the connection between the discs which face each other being effected through at least one arched blade integral with the 'one of the discs so that a simple axial thrust exerted on one of the two insulating bodies ensures the transmission of current.

On comprend que dans une telle structure, le maintien des deux corps isolants ne nécessite aucun organe de fixation puisqu'il suffit que les corps isolants emboîtés prennent appui contre des parties axialement fixes du dispositif de store. On conçoit par ailleurs que les opérations de branchement des conducteurs sur les disques annulaires sont susceptibles d'être réalisées en atelier, les deux corps du collecteur avec leurs connexions étant simplement emboîtés l'un dans l'autre au moment du montage dans le bâti.It is understood that in such a structure, the maintenance of the two insulating bodies does not require any fixing member since it suffices that the insulating bodies nested bear against axially fixed parts of the blind device. It is also understood that the operations of connecting the conductors to the annular discs are capable of being carried out in the workshop, the two bodies of the collector with their connections being simply fitted one inside the other at the time of mounting in the frame.

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 :
   Comme on l'a indiqué plus haut, fig. 1 est une coupe axiale schématique d'un dispositif de store à manoeuvre de secours intégrée, susceptible d'être équipé d'un collecteur rotatif suivant l'invention.
   Fig.2 est une coupe axiale à plus grande échelle, illustrant l'agencement d'un tel collecteur rotatif et le montage de celui-ci à l'intérieur du dispositif de store.

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:
As indicated above, fig. 1 is a schematic axial section of a blind device with integrated emergency operation, capable of being fitted with a rotary collector according to the invention.
Fig.2 is an axial section on a larger scale, illustrating the arrangement of such a rotary collector and the mounting thereof inside the blind device.
Fig. 3 illustrates in perspective the conformation of each of the two insulating bodies of the rotary collector according to FIG. 2.

En fig. 2, la référence 15 désigne l'arbre qui porte la roue creuse du système d'entraînement 9-10 renfermé par le carter latéral 8. L'extrémité libre de cet arbre 15 comporte une denture 15a formant planétaire pour les pignons satellites 16 du mécanisme épicycloïdal interposé entre le mécanisme de manoeuvre de secours et le bâti 2. Chaque pignon satellite 16, monté fou sur un axe 17 porté par la douille 7, engrène avec la denture intérieure 18a d'une bague 18 rendue solidaire du carter 8 afin d'être immobilisée angulairement et de permettre ainsi le fonctionnement du mécanisme épicycloïdal 15a-16 sus-indiqué.In fig. 2, the reference 15 designates the shaft which carries the hollow wheel of the drive system 9-10 enclosed by the side casing 8. The free end of this shaft 15 has a toothing 15 a forming a planetary gear for the planet gears 16 of the epicyclic mechanism interposed between the emergency operating mechanism and the frame 2. Each satellite pinion 16, idly mounted on an axis 17 carried by the sleeve 7, meshes with the internal toothing 18 a of a ring 18 made integral with the casing 8 so to be immobilized angularly and thus allow the operation of the above-mentioned epicyclic mechanism 15 a -16.

Sur l'arbre 15 est centré un premier corps isolant 19 à profil substantiellement tronconique et dont la paroi extérieure est profilée pour présenter trois gradins étagés 19a, chacun de ceux-ci formant appui pour un disque annulaire 20 en bronze au béryllium ou autre métal semblable bon conducteur de l'électricité.On the shaft 15 is centered a first insulating body 19 with a substantially frustoconical profile and the outer wall of which is profiled to present three stepped steps 19 a , each of these forming a support for an annular disc 20 made of beryllium bronze or other metal similar good conductor of electricity.

Fig. 3 fait bien apparaître l'agencement du corps 19 et de chaque disque 20. On notera en particulier que chaque gradin 19a comporte des évidements 19b aptes à former logements pour des oreilles radiales en saillie 20a prévues sur l'ouverture du disque 20 correspondant, lequel est ainsi retenu angulairement sur son gradin. Sa retenue dans le sens axial est assurée par de petites dents 19c ménagées sur les gradins 19a et en arrière desquelles vient s'encliqueter élastiquement le bord de l'ouverture du disque, à la manière illustrée en fig. 2.Fig. 3 clearly shows the arrangement of the body 19 and of each disc 20. It will be noted in particular that each step 19 a has recesses 19 b capable of forming housings for projecting radial ears 20 a provided on the opening of the disc 20 corresponding, which is thus angularly retained on its tier. Its retention in the axial direction is ensured by small teeth 19 c formed on the steps 19 a and behind which comes snap the edge of the opening of the disc, as illustrated in FIG. 2.

En ce qui concerne les connexions électriques, on observera que le corps isolant 19 est percé longitudinalement de trois canaux 19d qui ont été représentés sur le même plan longitudinal en fig. 2, alors qu'en fait et comme montré en fig. 3, pour des raisons évidentes de commodité et d'épaisseur, lesdits canaux sont angulairement décalés les uns par rapport aux autres, chacun d'eux s'ouvrant d'une part sur la face transversale à grand diamètre du corps 19, d'autre part au niveau de l'un des trois gradins 19a. Dans chaque canal 19d est introduit l'un des trois conducteurs 21a qui composent le câble 21 relié au moteur 3 à travers un passage longitudinal 7a de la douille 7 ; l'extrémité de chaque conducteur 21a est soudée au disque 20 correspondant au niveau d'une ouverture 20b pratiquée dans l'une des oreilles 20a de chaque disque.Regarding the electrical connections, we will observe that the body insulator 19 is pierced longitudinally with three channels 19 d which have been shown on the same longitudinal plane in FIG. 2, when in fact and as shown in fig. 3, for obvious reasons of convenience and thickness, said channels are angularly offset with respect to each other, each of them opening on the one hand to the large diameter transverse face of the body 19, on the other leaves at one of the three steps 19 a . In each channel 19 d is introduced one of the three conductors 21 a which make up the cable 21 connected to the motor 3 through a longitudinal passage 7 a of the socket 7; the end of each conductor 21 a is welded to the disc 20 corresponding to the level of an opening 20 b made in one of the ears 20 a of each disc.

Comme plus particulièrement montré en fig. 3, chaque disque 20 présente, préférablement au niveau de chacune des trois oreilles 20a, une lame 20c qui est obtenue par découpage et qui est cambrée vers l'extérieur afin de former organe collecteur de courant, comme on le comprendra mieux ci-après.As more particularly shown in fig. 3, each disc 20 has, preferably at each of the three ears 20 a , a blade 20 c which is obtained by cutting and which is arched outwards in order to form a current-collecting member, as will be better understood below. after.

Au corps isolant 19 ainsi constitué et équipé, auquel on peut affecter le qualificatif de "mâle", est associé un corps isolant creux, en conséquence de type "femelle", qui a été référencé 22 sur le dessin. Ce corps 22 est établi à un diamètre intérieur tel que le corps 19 est susceptible de venir s'y emboîter, et sa paroi intérieure comporte trois gradins étagés 22a correspondant aux trois gradins 19a sus-indiqués. Chaque gradin 22a, muni de dents 22d semblables à celles 19c des gradins 19a du corps 19, forme appui pour un disque métallique 23, également en bronze de béryllium, pourvu d'une oreille latérale 23a propre à venir s'engager dans l'un de trois logements longitudinaux 22b prévus à cet effet dans la paroi du corps 22. A chacun de ces logements 22b correspond un canal longitudinal 22c (fig. 2) pour le passage de l'un des conducteurs 12a du câble 12 qui provient du carter latéral 8 ; en fig. 2 on a supposé, pour la clarté du dessin, que les canaux 22c étaient disposés suivant le même plan longitudinal alors qu'en fait ils sont angulairement décalés les uns par rapport aux autres, comme cela apparaît en fig. 3. L'extrémité dénudée de chaque conducteur 12a est soudée à l'intérieur d'une perforation 23b pratiquée dans l'oreille 23a du disque 23 qui lui correspond.The insulating body 19 thus formed and equipped, to which one can assign the qualifier "male", is associated a hollow insulating body, consequently of the "female" type, which has been referenced 22 in the drawing. This body 22 is established at an internal diameter such that the body 19 is capable of coming to fit therein, and its internal wall comprises three stepped steps 22 a corresponding to the three steps 19 a above-mentioned. Each step 22 a , provided with teeth 22 d similar to those 19 c of steps 19 a of the body 19, form support for a metal disc 23, also in beryllium bronze, provided with a lateral ear 23 a suitable for coming engage in one of three longitudinal housings 22 b provided for this purpose in the wall of the body 22. To each of these housings 22 b corresponds a longitudinal channel 22 c (fig. 2) for the passage of one of the conductors 12 a cable 12 which comes from the side casing 8; in fig. 2 it has been assumed, for the sake of clarity of the drawing, that the channels 22 c are arranged in the same longitudinal plane when in fact they are angularly offset with respect to each other, as appears in FIG. 3. The stripped end of each conductor 12 a is welded inside a perforation 23 b formed in the ear 23 a of the disc 23 which corresponds to it.

On conçoit qu'une fois que les corps isolants 19 et 22, équipés de leurs disques respectifs 20 et 23 eux-mêmes reliés aux conducteurs 12a et 21a des câbles 12 et 21, ont été emboîtés l'un dans l'autre à la manière représentée en fig. 2, les lames cambrées 20c des disques 20 viennent élastiquement prendre appui contre les disques 23, en transmettant ainsi le courant quelle que soit l'orientation angulaire réciproque des deux corps 19 et 22.It is understood that once the insulating bodies 19 and 22, equipped with their respective disks 20 and 23 themselves connected to the conductors 12 a and 21 a cables 12 and 21 have been fitted into each other as shown in fig. 2, the cambered blades 20 c of the discs 20 come to bear elastically against the discs 23, thereby transmitting the current whatever the reciprocal angular orientation of the two bodies 19 and 22.

Le montage du collecteur rotatif ainsi agencé est très simple puisque le câblage est susceptible d'être effectué en atelier sur chacun des corps 19 ou 22 qui sont ensuite emboîtés et introduits en cet état à l'intérieur du dispositif de store lors de l'assemblage des éléments constitutifs de celui-ci à l'intérieur du bâti 2. Comme montré en fig. 2, la face transversale libre du corps 19 vient prendre appui contre les têtes débordantes des axes 17 des pignons satellites 16, tandis que la face transversable libre du corps femelle 22 vient s'adosser contre une pièce intérieure fixe 25, constituée dans le cas envisagé par un prolongement latéral cylindrique due carter 8. La poussée axiale ainsi déterminée provoque la déformation élastique des lames cambrées 20c et assure ainsi la transmission du courant. Aucune autre fixation ou assemblage n'est nécessaire, de telle sort qu'on obtient une simplification notable des opérations de montage, à laquelle vient s'ajouter une fiabilité totale tout au long de l'utilisation du dispositif de store.The assembly of the rotary collector thus arranged is very simple since the wiring is capable of being carried out in the workshop on each of the bodies 19 or 22 which are then fitted and introduced in this state inside the blind device during assembly. constituent elements thereof inside the frame 2. As shown in fig. 2, the free transverse face of the body 19 comes to bear against the overhanging heads of the axes 17 of the planet gears 16, while the free transversable face of the female body 22 comes to rest against a fixed inner part 25, constituted in the envisaged case by a cylindrical lateral extension of the casing 8. The axial thrust thus determined causes the elastic deformation of the arched blades 20 c and thus ensures the transmission of the current. No other fixing or assembly is necessary, such that a notable simplification of the assembly operations is obtained, to which is added total reliability throughout the use of the blind device.

Il convient encore d'observer que la pluralité des lames cambrées ou contacts 20c assure une transmission du courant dans d'excellentes conditions, notamment en ce qui concerne l'intensité susceptible d'être transmise.It should also be observed that the plurality of cambered blades or contacts 20 c ensures transmission of the current under excellent conditions, in particular as regards the intensity capable of being transmitted.

Rotary collector for a closure device having an electric winding and an emergency drive mechanism incorporated therein, characterised in that it comprises two insulating bodies, one male (19) and one female (22), which are designed to fit together one inside the other, and the walls of which, facing one another, have at least three staggered steps (19a, 22a) forming supports for annular metallic discs (20, 23) disposed in pairs and connected to two sets of electric conductors (21a, 12a), the connection between the two discs (20, 23) of one and the same pair being achieved through at least one bent strip (20c), which is integral with one of the discs (20) in such a way that a simple axial thrust, exerted upon one of the insulating bodies, ensures the transmission of the current.
  2. Collector according to claim 1, characterised in that each disc (20, 23) is retained angularly on its step (19a, 22a).
  3. Collector according to claim 2, characterised in that each step (19a, 22a) is cut out with at least one profiled recess (19b, 22b) to receive an interacting projecting radial portion (20a, 23a) provided on the corresponding disc (20, 23).
  4. Collector according to claim 3, characterised in that the connection between each of the discs (20, 23) and the electric conductors (21a, 12a) is achieved on a level with the projections (20a, 23a) of the respective disc.
  5. Collector according to any of claims 1 to 4, characterised in that each insulating body (19, 22) has longitudinal channels (19d, 22c) for the passage of the conductors.
  6. Collector according to any of claims 1 to 5, characterised in that at least some of the discs (20, 23) are retained axially on the corresponding step (19a, 22a).
  7. Collector according to claim 6, characterised in that the step (19a, 22a) has a projecting tooth (19c), behind which the edge of the opening of the corresponding disc (20, 23) resiliently engages.
