Description

La présente invention est relative à des perfectionnements apportés à des volets roulants. Elle vise plus particulièrement le mécanisme transmettant le mouvement de rotation issu d'une manivelle ou d'un moteur selon un axe déterminé, en un mouvement de rotation selon un axe généralement perpendiculaire, ce mouvement de rotation est transmis généralement à un treuil solidaire de l'arbre d'enroulement entraînant en translation le tablier du volet roulant.The present invention relates to improvements made to roller shutters. It relates more particularly to the mechanism transmitting the rotational movement from a crank or a motor along a determined axis, in a rotational movement along a generally perpendicular axis, this rotational movement is generally transmitted to a winch secured to the 'winding shaft driving the roller shutter deck in translation.

Les dispositifs connus sont généralement à double cardan et présentent les inconvénients majeurs suivants : les cardans traversant le bâti du volet roulant génèrent un important désaxage permanent, de l'ordre de 60°, qui d'une part, nuit au fonctionnement correct de la cinématique du volet rolant, créant un très mauvais rendement mécanique de l'ensemble, induisant de ce fait pour l'utilisateur un effort conséquent sur la manivelle pour vaincre le couple résistant important et affectant également la fiabilité des composants. On connaît également des renvois d'angle à 90° par association de deux pignons coniques. Néanmoins, cette solution requiert un montage soigné car les rattrapages de jeux sont quasiment inexistants, ce qui supprime toutes les possibilités de montage en faux équerrage entre l'axe du treuil du tambour du volet roulant et l'axe de manoeuvre. Par ailleurs, cette conception est d'un esthétisme peu avantageux car elle nécessite l'emploi de carters volumineux.Known devices are generally double gimbal and have the following major drawbacks: the gimbals passing through the frame of the roller shutter generate a significant permanent offset, of the order of 60 °, which on the one hand, affects the correct functioning of the kinematics of the rolant flap, creating a very poor mechanical performance of the assembly, thereby inducing for the user a significant effort on the crank to overcome the significant resistant torque and also affecting the reliability of the components. There are also known 90 ° bevel gears by association of two bevel gears. However, this solution requires careful assembly because the play take-up is almost nonexistent, which eliminates all possibilities of mounting in false squaring between the winch axis of the roller shutter drum and the operating axis. Furthermore, this design is of little aesthetic advantageous because it requires the use of large casings.

La présente invention vise donc à pallier ces inconvénients, en proposant un dispositif de renvoi d'angle, monté sur un bâti oscillant, qui autorise d'orienter l'axe du treuil du tambour, traversant le mur, dans une position telle qu'il soit colinéaire à l'axe de la manivelle.The present invention therefore aims to overcome these drawbacks, by proposing an angle deflection device, mounted on an oscillating frame, which allows the axis of the winch of the drum to be oriented, crossing the wall, in a position such that it either collinear with the axis of the crank.

A cet effet, le dispositif de renvoi d'angle, objet de l'invention, se caractérise en ce qu'il comprend un berceau formé de deux flancs parallèles et réunis par deux parois curvilignes, les faces internes desdits flancs étant munies en outre de saignées permettant le mouvement d'un boîtier comportant des logements au travers desquels est positionné un équipage de pignons comportant à chacune de leurs extrémités une zone d'engrènement et une tige autorisant la solidarisation avec l'axe du treuil du tambour du volet roulant et avec l'axe de manoeuvre, ledit berceau coopérant au pan de mur par l'intermédiaire d'une embase formant support.To this end, the angle transmission device, object of the invention, is characterized in that it comprises a cradle formed by two parallel sides and joined by two curvilinear walls, the internal faces of said sides being further provided with grooves allowing the movement of a box comprising housings through which is positioned a pinion assembly comprising at each of their ends an engagement zone and a rod allowing the fastening with the winch axis of the roller shutter drum and with the operating axis, said cradle cooperating with the wall section via a base forming a support.

Other characteristics and advantages of the present invention will emerge from the description given below, with reference to the appended drawings which illustrate an embodiment thereof devoid of any limiting character. In the figures:
  • Figure 1 is a sectional view, in front elevation, of a hinged angle gear according to the invention;
  • Figure 2 is a plan sectional view, in side elevation, of a bevel gear;
  • Figure 3 is a plan sectional view, in front elevation, of a sliding angle gear.

Selon un mode préféré de réalisation, le dispositif de renvoi d'angle, objet de l'invention, comporte essentiellement un berceau 1, formé par deux flancs 2, 3 parallèles réunis par deux parois 4, 5 curvilignes, de manière à constituer une boîte 6. Chacun des flancs 2, 3 est muni sur sa face intérieure 7, 8 d'une saignée 9 à empreinte plate ou sphérique ; ces empreintes coopèrent à un boîtier 10. Ce boîtier comporte également des parties latérales 11, 12 de profil similaire aux empreintes présentes sur les flancs 2, 3 du berceau 1, ces parties latérales étant réunies par l'intermédiaire d'une couronne 13. Le boîtier 10 est réalisé à partir d'une portion cylindrique et comprend notamment, sur la périphérie de la couronne 13, des logements 14, 14' faisant saillie perpendiculairement et débouchant, par l'une de leurs extrémités 15, 16, dans la cavité interne 17 de la portion cylindrique du boîtier 10. Par ailleurs, on prévoit de disposer ces logements 14, 14' selon un angle ouvert, compris entre l'angle droit et l'angle plat supérieur à l'angle droit, tel que notamment 120°. Chacun des logements 14, 14' reçoit en outre un équipage 20 de pignons 18, 19 dont l'inclinaison de la denture est fonction du décalage angulaire entre les deux axes respectifs des logements. Un équipage 20 comprend essentiellement, à l'une de ses extrémités 21, 22, une zone d'engrènement 23 portant la denture, tandis qu'à l'autre extrémité 24, 25, l'équipage 20 comporte une tige 26 qui s'adapte par des moyens connus tels que notamment par une empreinte en bout, du type six pans creux 27, ou par l'intermédiaire de perçages radiaux 28, afin d'en assurer sa solidarisation à l'axe issu de la manivelle 29, ou à l'axe 30 du treuil du tambour portant le tablier.According to a preferred embodiment, the angle transmission device, object of the invention, essentially comprises a cradle 1, formed by two parallel sides 2, 3 joined by two curved walls 4, 5, so as to constitute a box 6. Each of the sides 2, 3 is provided on its inner face 7, 8 with a groove 9 with a flat or spherical imprint; these imprints cooperate with a housing 10. This housing also includes lateral parts 11, 12 of profile similar to the imprints present on the sides 2, 3 of the cradle 1, these lateral parts being joined by means of a crown 13. The housing 10 is produced from a cylindrical portion and in particular comprises, on the periphery of the crown 13, housings 14, 14 ′ projecting perpendicularly and emerging, by one of their ends 15, 16, into the internal cavity 17 of the cylindrical portion of the housing 10. Furthermore, provision is made to arrange these housings 14, 14 ′ at an open angle, between the right angle and the flat angle greater than the right angle, such as in particular 120 ° . Each of the housings 14, 14 ′ further receives a team 20 of pinions 18, 19 whose inclination of the teeth depends on the angular offset between the two respective axes of the housings. A crew 20 essentially comprises, at one of its ends 21, 22, an engagement zone 23 carrying the toothing, while at the other end 24, 25, the crew 20 comprises a rod 26 which s adapts by known means such as in particular by an end cavity, of the hexagon socket type 27, or by means of radial bores 28, in order to ensure its attachment to the axis coming from the crank 29, or to axis 30 of the drum winch carrying the apron.

Les empreintes 9 présentes dans les flancs 2, 3 latéraux du berceau 1 autorisent une rotation ou un pivotement angulaire selon le type d'empreinte du boîtier 10 muni de son couple de renvoi d'angle. Afin de limiter l'amplitude du mouvement du boîtier 10, les ouvertures 31, 32 présentes sur les parois 4, 5 curvilignes et qui permettent le passage des logements 14, 14' sont de diamètre légèrement supérieur et peuvent si besoin être de forme oblongue.The imprints 9 present in the lateral flanks 2, 3 of the cradle 1 allow an angular rotation or pivoting according to the type of imprint of the housing 10 provided with its angular gear pair. In order to limit the amplitude movement of the housing 10, the openings 31, 32 present on the walls 4, 5 curvilinear and which allow the passage of the housing 14, 14 'are slightly larger in diameter and can if necessary be oblong.

Le berceau 1 coopère au pan de mur par l'intermédiaire d'une embase formant support 33. Ce support comprend une face plane 34 destinée à être au contact du pan de mur, tandis que la face opposée 35 est de profil curviligne, similaire à celui du berceau.The cradle 1 cooperates with the wall panel by means of a base forming a support 33. This support comprises a flat face 34 intended to be in contact with the wall panel, while the opposite face 35 is of curvilinear profile, similar to that of the cradle.

Le support 33 est par ailleurs pourvu d'une pluralité de trous 36, 37 pour le passage, d'une part d'un équipage 20 et d'autre part, pour les moyens de fixation tels que des vis, du support 33 sur le mur. Les moyens de fixation permettent également d'emprisonner, au niveau de lamages 39, 40, et donc de solidariser l'une des parois curvilignes 4, 5 constituant la boîte 6, grâce à l'appui du moyen de fixation sur un épaulement 38 réalisé sur une partie en retrait de l'une des parois curvilignes 4, 5.The support 33 is moreover provided with a plurality of holes 36, 37 for the passage, on the one hand of an assembly 20 and on the other hand, for the fixing means such as screws, of the support 33 on the Wall. The fixing means also make it possible to trap, at the countersinks 39, 40, and therefore to secure one of the curvilinear walls 4, 5 constituting the box 6, by virtue of the support of the fixing means on a shoulder 38 produced. on a part set back from one of the curvilinear walls 4, 5.

Selon un autre mode préféré de réalisation, on interpose entre le support 33 et le berceau 1 une glissière 41, la partie femelle étant éventuellement disposée sur le flanc 35 du support 33 et la partie mâle sur l'une des faces extérieures du berceau 1. La glissière 41 possède éventuellement une pluralité de surfaces de guidage, limitant ainsi les degrés de liberté du berceau 1 sur le support 33, à une seule direction. Dans ce mode de réalisation particulier, les moyens de fixation n'emprisonnent plus le berceau 1 sur le support 33, la solidarisation de ce dernier étant effectuée par la forme des glissières et notamment par leur profil en queue d'aronde. Par ailleurs, on prévoit que l'un des trous 36, 37 disposés dans l'embase du support et permettant le passage de l'équipage 20, est suffisamment important, ou est réalisé sous la forme d'une ouverture oblongue pour autoriser la course angulaire du berceau 1 sur le support 33 entre une position haute et une position basse.According to another preferred embodiment, a slide 41 is interposed between the support 33 and the cradle 1, the female part possibly being disposed on the side 35 of the support 33 and the male part on one of the external faces of the cradle 1. The slide 41 optionally has a plurality of guide surfaces, thus limiting the degrees of freedom of the cradle 1 on the support 33, to a single direction. In this particular embodiment, the fixing means no longer trap the cradle 1 on the support 33, the attachment of the latter being effected by the shape of the slides and in particular by their dovetail profile. Furthermore, provision is made for one of the holes 36, 37 arranged in the base of the support and allowing the passage of the crew 20, to be sufficiently large, or to be produced in the form of an oblong opening for authorize the angular travel of the cradle 1 on the support 33 between a high position and a low position.

Quel que soit le mode de réalisation du renvoi d'angle par articulation ou par glissière, le débattement angulaire entre l'axe du treuil du tambour du volet roulant et son axe de manoeuvre, par manivelle, est d'au moins 120° autour d'une position de montage du support par rapport à l'axe du volet roulant, étant entendu que le système d'articulation ou de glissière autorise un décalage angulaire autour de cette position de quelques degrés supplémentaires, préférentiellement de l'ordre de plus ou moins 5°, permettant ainsi de compenser les éventuelles tolérances dimensionnelles du mur.Whatever the embodiment of the bevel gear by articulation or by slide, the angular movement between the winch axis of the roller shutter drum and its operating axis, by crank, is at least 120 ° around d '' a mounting position of the support relative to the axis of the roller shutter, it being understood that the articulation or slide system allows an angular offset around this position of a few additional degrees, preferably of the order of more or less 5 °, thus making it possible to compensate for any dimensional tolerances of the wall.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.It remains to be understood that the present invention is not limited to the exemplary embodiments described and shown above, but that it encompasses all variants thereof.
