Abstract

The blind casing (1) is installed in the upper part of a window in front of which the blind is mounted. The casing encloses a blind winding drum. One of the side webs of this drum is fixed to a hollow wheel which meshes with an endless screw carried by the sloping operating rod (6). The rod is supported by a base plate (14), through which it passes, and is connected to a universal joint (16) on the crank handle (8) A pinned collar (11) fixes the operating rod to an end shaft (12) which passes through a directional nut (13) engaged in a support (14a) in the base plate. An intermediate square section piece (15) is interposed between the universal joint and the upper end of the crank handle. This allows, when required, the crank to be displaced and increase the opening angle of the window.

Description

On sait que les stores, volets roulants, grilles et autres fermetures à enroulement sont généralement équipés d'un dispositif de manivelle permettant d'assurer la commande manuelle du tambour d'envidage du tabLier, et ce dans Le cas des mécanismes d'entra;nement à main comme dans celui des systèmes de secours à utiliser lors des avaries du moteur associé au tambour précité. It is known that blinds, roller shutters, grilles and other roll-up closures are generally equipped with a crank device making it possible to ensure manual control of the drum for emptying the table, and this in the case of drive mechanisms; hand operation as in that of the emergency systems to be used in the event of engine damage associated with the aforementioned drum.

A la fig. 1 du dessin annexé aux présentes, on a schématiquement rappelé en coupe verticale l'agencement général et l'implantation des dispositifs de manivelle connus en pratique. Sur cette figure, la référence 1 désigne le coffre installé dans la partie supérieure de la fenêtre en avant de laquelle le store ou similaire est monté, lequel coffre renferme le tambour 2 pour l'envidage et le dévidage du tablier 3. L'une des joues latérales de ce tambour 2 est solidaire d'une roue creuse 4 qui coopère avec une vis sans fin 5 portée par une tige d'actionnement 6 orientée obliquement. Cette dernière est supportée par une platine 7 qu'elle traverse pour être équipée, par le moyen d'un joint à la Cardan, d'une manivelle de manoeuvre 8. In fig. 1 of the drawing appended hereto, the general arrangement and layout of the crank devices known in practice have been schematically recalled in vertical section. In this figure, the reference 1 designates the trunk installed in the upper part of the window in front of which the blind or the like is mounted, which trunk contains the drum 2 for the emptying and unwinding of the deck 3. One of the side cheeks of this drum 2 is secured to a hollow wheel 4 which cooperates with an endless screw 5 carried by an actuating rod 6 oriented obliquely. The latter is supported by a plate 7 which it passes through to be equipped, by means of a Cardan joint, with an operating crank 8.

La position de l'extrémité de la tige 6 et du joint qui lui est fixé est imposée par la construction du système vis sans fin/roue creuse, de sorte que comme illustré sur la coupe horizontale schématique suivant fig. 2, la manivelle 8 limite l'angle d'ouverture du vantail articulé 10 de la fenêtre. The position of the end of the rod 6 and of the seal attached to it is imposed by the construction of the worm / hollow wheel system, so that as illustrated in the schematic horizontal section according to FIG. 2, the crank 8 limits the opening angle of the hinged leaf 10 of the window.

C'est à cet inconvénient qu'entend remédier la présente invention, laquelle consiste essentiellement à interposer entre le joint à la
Cardan lié à la tige oblique d'actionnement et l'extrémité supérieure de la manivelle une pièce de liaison à profil en équerre qui permet d'amener, lorsque désiré, ladite manivelle à une position décalée qui augmente sensiblement l'angle d'ouverture du vantail.
It is to this drawback that the present invention intends to remedy, which essentially consists in interposing between the seal at the
Cardan linked to the oblique actuating rod and the upper end of the crank a connecting piece with an angled profile which makes it possible to bring, when desired, said crank to an offset position which substantially increases the opening angle of the leaf.

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 indiqué plus haut, fig. 1 et 2 sont des coupes verticale, respectivement horizontale, illustrant l'agencement et l'implantation des dispositifs de manivelle classiques.
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 and 2 are vertical sections, respectively horizontal, illustrating the arrangement and installation of conventional crank devices.

Fig. 3 est une coupe axiale à plus grande échelle montrant un dispositif établi conformément à la présente invention. Fig. 3 is an axial section on a larger scale showing a device established in accordance with the present invention.

Fig. 4 représente en perspective, à l'état démonté, les pièces qui constituent le dispositif suivant fig. 3. Fig. 4 shows in perspective, in the disassembled state, the parts which constitute the device according to FIG. 3.

Fig. 5 et 6 sont des coupes schématiques similaires à celles suivant fig. 1 et 2, mais correspondant au montage du dispositif suivant fig. 3. Fig. 5 and 6 are schematic sections similar to those according to FIG. 1 and 2, but corresponding to the mounting of the device according to fig. 3.

En fig. 3, on peut voir en 6 l'extrémité inférieure de la tige oblique d'actionnement qui porte à son sommet la vis sans fin 5 de fig. 1. Une bague goupillée 11 assure la solidarisation de cette tige 6 avec un bout d'arbre 12 qui traverse une noix orientable 13 engagée dans un berceau 14a ménagé dans une platine 14, laquelle est destinée à être fixée contre la face inférieure du coffre 1 du store ou similaire. In fig. 3, we can see at 6 the lower end of the oblique actuation rod which carries at its top the worm 5 of FIG. 1. A pinned ring 11 secures this rod 6 with a shaft end 12 which passes through an orientable nut 13 engaged in a cradle 14a formed in a plate 14, which is intended to be fixed against the underside of the trunk 1 blind or similar.

Conformément à L'invention et comme plus particulièrement montré en fig. 4, sur L'extrémité supérieure de la manivelle 8 est goupillée une pièce 15 à profil en équerre qui est rendue solidaire du bout d'arbre 12 par L'intermédiaire d'un joint à la Cardan 16. In accordance with the invention and as more particularly shown in FIG. 4, on the upper end of the crank 8 is pinned a piece 15 with an angled profile which is made integral with the end of the shaft 12 by means of a cardan joint 16.

La présence de la pièce intermédiaire 15 ne modifie pas le fonctionnement et la manoeuvre du dispositif de manivelle, en ce sens que la rotation impartie manuellement à la manivelle 8 assure bien la commande de la vis sans fin 5 et du tambour 2, comme dans les dispositifs usuels. The presence of the intermediate piece 15 does not modify the operation and the maneuvering of the crank device, in the sense that the rotation imparted manually to the crank 8 does indeed control the worm 5 and the drum 2, as in usual devices.

Par contre et comme illustré en fig. 5 et 6, cette pièce 15 permet à l'utilisateur, lorsqu'il a amené le tablier 3 à la position désirée, de rabattre la manivelle 8 contre le montant du dormant 9, ladite manivelle affectant alors une position éclipsée disposée latéralement par rapport à L'aplomb de l'extrémité du bout d'arbre 12. L'amplitude d'ouverture du vantail 10 est ainsi sensiblement augmentée.On the other hand and as illustrated in fig. 5 and 6, this part 15 allows the user, when he has brought the apron 3 to the desired position, to fold the crank 8 against the amount of the frame 9, said crank then affecting an eclipsed position arranged laterally with respect to The vertical alignment of the end of the shaft end 12. The opening amplitude of the leaf 10 is thus significantly increased.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de L'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
