The crank handle for manually operating the winding mechanism of roller blinds comprises a base plate (8) which is fixed against the floor (1a) of the blind casing (1). Pivoted parts carried by the plate connect the handle (13) to a sloping operating rod (6) of the winding mechanism. The base plate has a transverse tubular boss (8a) forming a bearing for a small vertical shaft (11) whose lower end carries the universal joint (12) connected to the handle. The shaft upper end is connected by a universal joint (14) to the sloping operating rod. The base plate has a second tubular boss (8b), parallel to the first, through which a screw (10) passes to hold an upper plate (9) for fixing the base plate to the floor.

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'entraînement 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 deck's drum for emptying, and this in the case of drive mechanisms with hand as in that of the emergency systems to be used during engine damage associated with the aforementioned drum.

Les dispositifs de manivelle connus en pratique comprennent ordinairement une platine qui est destinée à être fixée contre la face extérieure du plancher du coffre qui renferme le tambour d'envidage et le mécanisme d'entraînement du store ou similaire. Cette platine comporte vers le bas une partie à profil sphérique formant berceau pour une boule orientable qui est traversée de part en part par une tige d'entraînement. L'une des extrémités de cette tige pénètre à l'intérieur du coffre pour porter la vis sans fin coopérant avec la roue creuse usuelle fixée latéralement en bout du tambour d'envidage, tandis que l'extrémité inférieure opposée est pourvue d'un système de Cardan lié vers le bas à la manivelle de manoeuvre proprement dite. Crank devices known in practice ordinarily comprise a plate which is intended to be fixed against the external face of the floor of the boot which encloses the idling drum and the drive mechanism of the blind or the like. This plate comprises downwards a part with a spherical profile forming a cradle for an orientable ball which is crossed right through by a drive rod. One end of this rod penetrates inside the trunk to carry the worm cooperating with the usual hollow wheel fixed laterally at the end of the idling drum, while the opposite lower end is provided with a system of Cardan linked down to the actual operating crank.

Une telle construction permet bien d'orienter la tige d'entraînement pour que sa vis sans fin puisse coopérer dans les meilleures conditions mécaniques avec la roue creuse du tambour. Par contre, elle est assez complexe et elle présente l'inconvénient de s'étendre totalement vers le bas, en accroissant ainsi la hauteur de la partie du dispositif qui est disposée au-dessous du plancher du coffre. Par suite de l'obliqui té de la tige d'entraînement, on est ainsi obligé de placer la manivelle à une certaine distance du dormant de la menuiserie, ce qui limite l'angle d'ouverture de la fenêtre. Such a construction makes it possible to orient the drive rod so that its worm can cooperate under the best mechanical conditions with the hollow wheel of the drum. On the other hand, it is quite complex and it has the drawback of extending completely downwards, thereby increasing the height of the part of the device which is arranged below the floor of the boot. As a result of the obliquity of the drive rod, it is thus necessary to place the crank at a certain distance from the frame of the joinery, which limits the opening angle of the window.

C'est à cet inconvénient qu'entend principalement remédier la présente invention. It is to this drawback that the present invention mainly intends to remedy.

Conformément à l'invention, la platine du dispositif comporte un bossage transversal tubulaire formant palier pour un petit arbre vertical dont l'extrémité inférieure porte, à la façon usuelle, un Cardan pour sa liaison avec la tige de la manivelle, tandis que son extrémité supérieure est reliée par un joint universel à La tige d'entraînement associée à la vis sans fin. According to the invention, the plate of the device comprises a transverse tubular boss forming a bearing for a small vertical shaft whose lower end carries, in the usual way, a Cardan joint for its connection with the rod of the crank, while its end upper is connected by a universal joint to the drive rod associated with the worm.

On comprend que dans un tel agencement, le joint à la Cardan qui assure la jonction entre l'arbre vertical et la tige de la manivelle peut être prévu contre la face extérieure du dormant horizontal de la menuiserie, ce qui permet d'accroître L'angle d'ouverture de la fenêtre du fait que la manivelle ne constitue plus une gêne.  It is understood that in such an arrangement, the joint to the gimbal which provides the junction between the vertical shaft and the rod of the crank can be provided against the outer face of the horizontal frame of the carpentry, which increases L ' window opening angle due to the fact that the crank is no longer a nuisance.

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
Fig. 1 est une coupe verticale schématique illustrant l'implantation d'un dispositif de manivelle suivant l'invention dans le coffre d'un 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.

Fig. 3 représente en perspective, à l'état séparé, les trois éléments qui constituent la platine. Fig. 3 shows in perspective, in a separate state, the three elements which constitute the plate.

Fig. 4 illustre une variante de mise en oeuvre de l'invention. Fig. 4 illustrates a variant implementation of the invention.

Fig. 5 est une coupe horizontale illustrant le positionnement du dispositif par rapport à l'axe de pivotement du vantail. Fig. 5 is a horizontal section illustrating the positioning of the device relative to the pivot axis of the leaf.

En fig. 1, la référence 1 désigne un coffre de type usuel, renfermant l'ensemble du mécanisme d'un store classique dont on aperçoit en 2 le tambour pour l'envidage et le dévidage du tablier 3. Contre L'une des joues latérales de ce tambour 2 est fixée une roue creuse 4 qui coopère avec une vis sans fin 5 portée par une tige d'entraînement 6, laquelle est orientée obliquement. In fig. 1, the reference 1 designates a chest of the usual type, containing the entire mechanism of a conventional blind, of which we see at 2 the drum for the emptying and unwinding of the apron 3. Against one of the side cheeks of this drum 2 is fixed a hollow wheel 4 which cooperates with an endless screw 5 carried by a drive rod 6, which is oriented obliquely.

Le dispositif de manivelle suivant l'invention, référencé globalement 7 en fig. 1, est porté par le plancher la du coffre 1 et il est destiné à opérer, à la façon connue, l'entraînement de la vis 5 pour la manoeuvre manuelle du tambour 2 et du tablier 3. The crank device according to the invention, generally referenced 7 in FIG. 1, is carried by the floor 1a of the boot 1 and it is intended to operate, in the known manner, the driving of the screw 5 for the manual operation of the drum 2 and of the deck 3.

Comme montré en fig. 2, ce dispositif 7 comprend en premier lieu une platine qui est constituée par une semelle 8 pourvue de deux bossages tubulaires 8a et 8b de hauteur inégale, orientés transversalement au-dessus de ladite semelle 8. Le bossage le plus haut 8a présente une gorge annulaire 8c (cf. fig. 3) propre à recevoir l'entai île latérale 9a d'une plaquette de retenue 9, taraudée en 9b suivant l'axe du bossage 8b de la semelle 8. As shown in fig. 2, this device 7 firstly comprises a plate which is constituted by a sole 8 provided with two tubular bosses 8a and 8b of unequal height, oriented transversely above said sole 8. The highest boss 8a has an annular groove 8c (cf. fig. 3) suitable for receiving the lateral island section 9a of a retaining plate 9, tapped at 9b along the axis of the boss 8b of the sole 8.

Le plancher la du coffre 1 est percé de deux trous dont l'écartement correspond à celui des bossages 8a et 8b de la semelle, qui peuvent ainsi être introduits en place de bas en haut. Une fois l'entai île 9a de la plaquette 9 logée dans la gorge 8c, il suffit au monteur d'engager dans le bossage 8b une vis telle que 10 qui traverse le plancher la et vient se visser dans le taraudage 9b de ladite plaquette 9. La platine 8-9 est ainsi fermement fixée au coffre 1. The floor 1a of the trunk 1 is pierced with two holes whose spacing corresponds to that of the bosses 8a and 8b of the sole, which can thus be introduced in place from the bottom up. Once the island 9a of the plate 9 is housed in the groove 8c, it is sufficient for the fitter to engage in the boss 8b a screw such as 10 which crosses the floor 1a and is screwed into the tapping 9b of said plate 9 The plate 8-9 is thus firmly fixed to the trunk 1.

Dans l'ouverture axiale du bossage 8a de cette platine tourillonne un petit arbre vertical 11 dont l'extrémité inférieure reçoit un joint à la Cardan 12 pour son assemblage articulé avec la manivelle usuelle de manoeuvre 13. L'extrémité supérieure de cet arbre 11 qui dépasse audessus de la plaquette 9 forme entrée pour un autre joint à la Cardan, référencé 14, qui assure la commande en rotation de la tige oblique d'actionnement 6 qui porte la vis sans fin 5. In the axial opening of the boss 8a of this plate journals a small vertical shaft 11, the lower end of which receives a Cardan joint 12 for its articulated assembly with the usual operating crank 13. The upper end of this shaft 11 which protrudes above the plate 9 in the form of an input for another Cardan joint, referenced 14, which ensures the rotation control of the oblique actuation rod 6 which carries the worm 5.

Le fonctionnement d'un tel dispositif de manivelle est identique à celui des mécanismes classiques, en ce sens que la manoeuvre de la manivelle 13 assure la rotation de la tige 6 et l'actionnement du tambour 2. Néanmoins, la tige de manivelle 13 se trouve positionnée au plus près du dormant 15, pratiquement au même niveau que l'axe des paumelles 17 du vantail 15. Dans ces conditio comme illustré en fig. 5, le dispositif 7 ne gêne pas la manoeuvre du vantail à l'ouverture et à la fermeture. The operation of such a crank device is identical to that of conventional mechanisms, in that the operation of the crank 13 ensures the rotation of the rod 6 and the actuation of the drum 2. However, the crank rod 13 is is positioned as close as possible to the frame 15, practically at the same level as the axis of the hinges 17 of the leaf 15. In these conditions as illustrated in FIG. 5, the device 7 does not interfere with the operation of the leaf when opening and closing.

On conçoit sans peine que le joint à la Cardan supérieur 14 peut être remplacé par tout autre joint universel, notamment par un flexible du genre de celui qui est indiqué en 14' en fig. 4. It is easy to see that the upper universal joint 14 can be replaced by any other universal joint, in particular by a flexible hose of the type indicated in 14 ′ in FIG. 4.

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 foregoing 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.
