The casing (2) has a loose anchoring flange (12), allowing the input shaft (3) to be set at the desired angle. The flange can be at right angles to the output shaft and parallel to the input one, while part at least of it can protrude beyond the casing.

Description

La présente invention concerne un mécanisme de commande pour enrouler et dérouler un écran de protection assemblé dans un caisson aménagé dans la fenêtre ou dans une cavité de la maçonnerie, comprenant un entraînement par vis sans fin avec axes entrant et sortant ainsi qu'un boîtier orientable, que l'on fixe à une paroi du caisson protecteur avec une inclinaison dépendant de l'encombrement du seuil supérieur de la fenêtre.The present invention relates to a control mechanism for winding and unwinding a protective screen assembled in a box arranged in the window or in a cavity of the masonry, comprising a drive by endless screw with incoming and outgoing axes as well as an orientable housing. , which is fixed to a wall of the protective box with an inclination depending on the size of the upper threshold of the window.

Elle permet une standardisation du matériel à utiliser pour placer rapidement un système d'enroulement et de fixation pour écrans solaires, tentes solaires, écran d'occultation, toiles de protection, écrans d'ombrage intérieurs et extérieurs, stores rabattus, volets roulants, écrans contre le vent et voiles devant être placés dans des caissons de protection où l'encombrement rend les conditions difficiles.It allows standardization of the equipment to be used to quickly place a winding and fixing system for sunscreens, sun tents, blackout screens, protective sheets, indoor and outdoor shade screens, folded blinds, roller shutters, screens against the wind and sails to be placed in protective boxes where space makes conditions difficult.

On connaît, par le brevet français N° 1587117, un mécanisme de commande pour enrouler un écran solaire, dont le boîtier est pourvu d'une bride d'ancrage fixe qui présente des rainures en forme d'arc de cercle, afin de permettre un montage du mécanisme de commande dans des positions inclinées variables.French patent No. 1587117 discloses a control mechanism for winding a sunscreen, the housing of which is provided with a fixed anchoring flange which has grooves in the shape of an arc of a circle, in order to allow a mounting of the control mechanism in variable inclined positions.

Des écrans d'ombrage sont généralement placés dans des caissons de protection disposés au-dessus ou derrière le seuil supérieur ou même dans des caissons qui sont encastrés directement dans les fenêtres. Selon le mode d'assemblage et selon l'encombrement, l'accouplement de l'organe d'entraînement, comme par exemple la tige-manivelle, doit être réalisée sur le côté sous différents angles d'inclinaison ou même le long du côté inférieur du caisson de protection. Le choix de l'angle d'inclinaison dépend de la pente du pied de l'organe de fixation de la tige-manivelle. L'accouplement de la tige manivelle éventuellement démontable est souvent réalisée à l'aide d'une articulation à genoullère.Shading screens are generally placed in protective boxes placed above or behind the upper threshold or even in boxes which are embedded directly in the windows. Depending on the method of assembly and the size, the coupling of the drive member, such as the crank rod, must be carried out on the side at different angles of inclination or even along the lower side of the protective casing. The choice of angle of inclination depends on the slope of the base of the fixing member of the crank rod. The coupling of the possibly removable crank rod is often carried out using a knee joint.

Les brides de fixation du mécanisme de commande connu par le brevet français N8 1587117 ne tolèrent qu'une liberté d'orientation limitée lors du montage du mécanisme de commande.The clamps for fixing the control mechanism known from French patent N 8 1587117 tolerate only limited freedom of orientation during the mounting of the control mechanism.

Le serrage des pièces de fixation des brides est peu commode parce qu'il ne peut être effectué que lorsque le boîtier est mis en place avec précision.Tightening the flange fasteners is inconvenient because it can only be done when the housing is precisely positioned.

Par le brevet français 1486480, on connaît également un mécanisme pour la commande des volets roulants, qui est logé dans un boîtier formé de deux moitiés identiques pourvues d'un anneau latéral à denture radiale. Cet anneau est appliqué suivant une orientation angulaire quelconque contre une rondelle également dentée qu'on fixe sur une plaque susceptible d'être scellée dans le mur. Le réglage de l'inclinaison ne peut se faire que de manière discrète.By French patent 1486480, there is also known a mechanism for controlling roller shutters, which is housed in a housing formed by two identical halves provided with a lateral ring with radial toothing. This ring is applied in any angular orientation against a washer also toothed that is fixed on a plate capable of being sealed in the wall. The tilt adjustment can only be done discreetly.

L'inconvénient de ce dispositif connu consiste, comme dans le cas précédent, dans le fait que le serrage des pièces de fixation ne peut être réalisé qu'après avoir orienté le boîtier dans la direction souhaitée. Ce dispositif est constitué de diverses pièces distinctes pouvant se perdre facilement.The drawback of this known device consists, as in the previous case, in the fact that the tightening of the fastening parts can only be carried out after having oriented the housing in the desired direction. This device consists of various separate parts that can be easily lost.

La présente invention vise à éviter les désavantages susdits. Elle propose une armature qui permette un montage facile. Elle concerne un mécanisme de commande pour enrouler et dérouler un écran de protection assemblé dans un caisson aménagé dans la fenêtre ou dans une cavité de la maçonnerie, comprenant un entraînement par vis sans fin avec axes entrant et sortant ainsi qu'un boîtier orientable, que l'on fixe à une paroi du caisson protecteur avec une inclinaison dépendant de l'encombrement du seuil supérieur de la fenêtre, essentiellement caractérisé en ce que le boîtier comprend une bride d'ancrage mobile, qui permette d'adapter librement l'angle d'inclinaison de l'axe entrant.The present invention aims to avoid the above disadvantages. It offers a frame that allows easy assembly. It relates to a control mechanism for winding and unwinding a protective screen assembled in a box arranged in the window or in a cavity of the masonry, comprising a drive by endless screw with incoming and outgoing axes as well as an orientable housing, which it is fixed to a wall of the protective box with an inclination depending on the size of the upper threshold of the window, essentially characterized in that the housing comprises a movable anchoring flange, which allows the angle d to be freely adapted tilt of the incoming axis.

La bride d'ancrage est de préférence parallèle à l'axe entrant.The anchoring flange is preferably parallel to the incoming axis.

Suivant une particularité de l'invention, une partie du rebord extérieur déborde du boîtier.According to a feature of the invention, part of the outer rim projects beyond the housing.

Dans une forme de réalisation particulière, l'axe sortant est un noyau creux percé de part en part.In a particular embodiment, the outgoing axis is a hollow core drilled through.

Suivant une autre particularité de l'invention, la bride d'ancrage sur le pourtour du côté extérieur, de saillies qui sont éventuellement pourvues de filets.According to another feature of the invention, the anchoring flange on the periphery of the outer side, projections which are optionally provided with threads.

Ces caractéristiques et détails, ainsi que d'autres, sont explicités plus en détail à l'aide des dessins ci- joints qui montrent une forme spécifique de réalisation de l'invention comme exemple non limitatif.These characteristics and details, as well as others, are explained in more detail with the aid of the attached drawings which show a specific embodiment of the invention as a non-limiting example.

Dans ces dessins, les mêmes notations de référence des éléments identiques ou analogues.In these drawings, the same reference notations of identical or analogous elements.

Comme illustré àn la figure 1, un mécanisme de commande pour enrouler et dérouler un écran d'ombrage, désigné dans son ensemble par le numéro de référence 1, un boîtier d'engrenage à vis 2 avec axe entrant 3, muni d'une rampe à six pans destinée à recevoir une extrémité hexagonale d'un organe d'entraînement 4 et un axe sortant 5 creux, également sur lequel repose une barre creuse d'enroulement 6.As illustrated in FIG. 1, a control mechanism for winding and unwinding a shading screen, generally designated by the reference number 1, a worm gear box 2 with incoming axis 3, provided of a hexagonal ramp intended to receive a hexagonal end of a drive member 4 and a hollow outgoing axis 5, also on which a hollow winding bar 6 rests.

Un élément de protection 7 de l'écran d'ombrage et le mécanisme de commande 1 sont le plus souvent disposés dans un caisson de protection 8, dans lequel la barre d'enroulement 6, à une extrémité, repose sur un palier en forme de U, non montré, et à l'autre extrémité sur le mécanisme de commande 1 lui-même.A protective element 7 of the shading screen and the control mechanism 1 are most often arranged in a protective box 8, in which the winding bar 6, at one end, rests on a bearing in the form of U, not shown, and at the other end on the control mechanism 1 itself.

Ce mécanisme correspond à un boîtier d'engrenage à vis 2 avec entraînement à vis auto-freinant, un axe entrant 3 creux, auquel on fixe une tige-manivelle 4 également démontable et un axe sortant 5 creux, destiné à supporter une extrémité de la barre d'enroulement 6 à actionner.This mechanism corresponds to a screw gearbox 2 with self-braking screw drive, a hollow input shaft 3, to which is fixed a crank rod 4 also removable and a hollow output shaft 5, intended to support one end of the winding bar 6 to be actuated.

Le caisson de protection 8 est généralement réalisé en profilés d'aluminium, mais on peut aussi utiliser du bois et de la matière synthétique. Il peut être incorporé à un châssis de fenêtre 9 ou dans un mur-rideau 10. Il peut aussi être placé au-dessus du châssis de fenêtre 9, derrière celui-ci ou même en-dessous du seuil supérieure 11.The protective box 8 is generally made of aluminum profiles, but it is also possible to use wood and synthetic material. It can be incorporated into a window frame 9 or into a curtain wall 10. It can also be placed above the window frame 9, behind it or even below the upper threshold 11.

Selon le type de caisson, l'axe soprtant 5 doit être dirigé vers le bas ou sur le côté, afin de permettre l'accouplement de la tige-manivelle 4 par le côté inférieur (figure 1) ou latéralement (figure 2).Depending on the type of box, the supporting axis 5 must be directed downwards or to the side, in order to allow the coupling of the crank rod 4 from the lower side (Figure 1) or laterally (Figure 2).

Le réglage de l'inclinaison du boîtier d'engrenage à vis 2 est toujours difficile dans les systèmes connus et exige dans divers cas la fabrication de pièces particulières lorsque la modification angulaire souhaitée est supérieure à 90°.Adjusting the inclination of the screw gear housing 2 is always difficult in known systems and in various cases requires the manufacture of particular parts when the desired angular modification is greater than 90 °.

Selon l'invention, la bride d'ancrage 12 de l'entraînement à vis tourne librement contre un côté du boîtier d'engrenage à vis 2 du mécanisme, autour de l'axe commun de l'arbre sortant 5 et de la barre d'enroulement 6.According to the invention, the anchor flange 12 of the screw drive rotates freely against one side of the screw gear housing 2 of the mechanism, around the common axis of the outgoing shaft 5 and the bar d winding 6.

De ce fait, le boîtier 2 est rendu librement orientable et peut prendre une position arbitraire, même lorsque la bride d'ancrage est fixée à une paroi d'extrémité du caisson de protection 8.As a result, the box 2 is made freely orientable and can take an arbitrary position, even when the anchoring flange is fixed to an end wall of the protective box 8.

L'axe entrant 3 peut prendre n'importe quelle orientation. La liberté de rotation du mécanisme de commande rend la mise en place d'une tige-manivelle bien plus simple.The incoming axis 3 can take any orientation. The freedom of rotation of the control mechanism makes the installation of a crank rod much simpler.

La bride d'ancrage libre 12 selon l'invention, simplifie aussi le mode de construction au cas où un élément est accouplé. Les différences et les dissimilitudes dans les diverses parties d'une fenêtre 9 n'exigent aucunes modifications particulières et du travail de montage, parce que le caisson extérieur des pièces de commande accouplées, peuvent subir un mouvement relatif de rotation.The free anchor flange 12 according to the invention also simplifies the method of construction in the event that an element is coupled. The differences and dissimilarities in the various parts of a window 9 require no particular modifications and assembly work, because the external casing of the coupled control parts, can undergo a relative movement of rotation.

La rotation de la tige-manivelle 4 est transmise au mécanisme de commande 1 généralement au moyen d'une articulation à grenouillère 13 (figure 3). La bride d'ancrage 12 est alors aussi parallèle à l'axe entrant 3.The rotation of the crank rod 4 is transmitted to the control mechanism 1 generally by means of a toggle joint 13 (Figure 3). The anchoring flange 12 is then also parallel to the incoming axis 3.

Au moins une partie du bord de la bride d'ancrage 12 forme une paroi extérieure à laquelle on fixe le boîtier 13 de l'entraînement à vis.At least part of the edge of the anchoring flange 12 forms an outer wall to which the housing 13 of the screw drive is fixed.

L'axe sortant 5 traverse la bride d'ancrage circulaire au centre et présente de part en part, un évidement carré illustré à la figure 4.The outgoing axis 5 crosses the circular anchoring flange in the center and presents right through, a square recess illustrated in FIG. 4.

Comme montré aux figures 5 à 13, la bride d'ancrage 12 pivotant librement est fixée à l'aide d'un anneau prisonnier 14 sur un rebord du boîtier 2 qui entoure l'axe sortant 5. L'anneau prisonnier 14 est fixé sur la partie frontale du boîtier 2 à l'aide de deux vis 15. L'anneau prisonnier 14 peut aussi être fixé sur le boîtier 2 par une presse à emboutir.As shown in Figures 5 to 13, the freely pivoting anchor flange 12 is fixed with a captive ring 14 on a flange of the housing 2 which surrounds the outgoing axis 5. The captive ring 14 is fixed on the front part of the housing 2 using two screws 15. The captive ring 14 can also be fixed to the housing 2 by a stamping press.

La bride d'ancrage 12 présente à son pourtour des saillies 16 d'environ 1 mm d'épaisseur, éventuellement munies de filets 17, afin que la tête d'une vis ou d'un clou ou d'un autre moyen de fixation, n'empêche pas la libre rotation du boîtier extérieur.The anchoring flange 12 has at its periphery protrusions 16 of about 1 mm thick, possibly provided with threads 17, so that the head of a screw or a nail or other fixing means, does not prevent the free rotation of the external housing.

Le libre pivotement de la bride d'ancrage 12 selon l'invention, procure au mécanisme de commande les avantages suivants :

  • - possibilité d'orienter le mécanisme de commande après fixation de celui-ci grâce à la libre rotation sur 360° autour de l'axe coaxial de la bride d'ancrage;
  • - forme de réalisation solide et compacte;
  • - standardisation poussée;
  • - montage simple.
The free pivoting of the anchoring flange 12 according to the invention provides the following advantages to the control mechanism:
  • - possibility of orienting the control mechanism after fixing it thanks to the free rotation over 360 ° around the coaxial axis of the anchoring flange;
  • - solid and compact embodiment;
  • - advanced standardization;
  • - simple assembly.

Il est évident que l'invention n'es aucunement limitée aux formes de réalisation décrites ci-dessus, qui sont plutôt données à titre d'exemples auxquels on peut apporter de nombreuses modifications sans sortir du cadre de l'invention.It is obvious that the invention is in no way limited to the embodiments described above, which are rather given by way of examples to which numerous modifications can be made without departing from the scope of the invention.
