Description

L'invention a pour objet un dispositif d'enroulement de cordon de suspension de store comprenant un tambour d'enroulement, sur lequel est fixée l'extrémité d'au moins un cordon de suspension, et des moyens pour assurer un enroulement du cordon en spires régulières sans chevauchement.The subject of the invention is a winding device for blind hanging cord including a drum winding, on which is fixed the end of at minus a hanging cord, and means for ensure a winding of the cord in regular turns without overlap.

Les stores, qu'il s'agisse de toiles, de stores vénitiens, de stores plissés ou autres, comportent généralement deux cordons de suspension dont une extrémité est fixée au tambour d'enroulement et l'autre extrémité est fixée à l'extrémité libre du store. Afin d'assurer un enroulement et un déroulement régulier du store, c'est-à-dire une descente et une montée égales des deux côtés du store, pour des raisons d'esthétique et des raisons mécaniques (risque de coincement) il est nécessaire d'assurer un enroulement régulier des deux cordons de suspension sur le tambour d'enroulement, en spires régulières, sans chevauchement. A cet effet, il est connu d'animer le tambour d'enroulement d'un mouvement de translation simultané au mouvement de rotation et d'amplitude telle que cette translation soit au moins égale à la valeur du diamètre du cordon par tour de tambour. De telles réalisations sont décrites dans les brevets FR-A-1 234 045, FR-A-1 319 645, CH-A-400 816, CH-A-408 694, EP-A-380 346. Le tambour d'enroulement déplaçable axialement comporte à une extrémité une partie filetée. Une partie filetée correspondante doit être prévue sur son support. De l'autre côté, réservé à son entraínement, un aménagement doit être prévu pour permettre à la fois l'entraínement en rotation et la translation induite par les parties filetées. Tout ceci est source de complications et de surcoûts. De plus, les espaces nécessaires au déplacement axial doivent être laissés libres et dans certaines réalisations (CH-A-400 816) ils constituent des espaces morts qui augmentent l'encombrement du support du store.Blinds, whether canvases, blinds Venetian blinds, pleated blinds or other, have usually two suspension cords, one of which one end is attached to the winding drum and the other end is fixed to the free end of the blind. To ensure regular winding and unwinding of the blind, i.e. an equal descent and ascent on both sides of the blind, for aesthetic reasons and mechanical reasons (risk of jamming) it is necessary to ensure a regular winding of the two suspension cords on the winding drum, in regular turns, without overlapping. To this end, it is known to animate the winding drum of a translational movement simultaneous with the movement of rotation and amplitude such that this translation is at least equal to the value of the cord diameter per drum revolution. Such achievements are described in patents FR-A-1,234,045, FR-A-1,319,645, CH-A-400 816, CH-A-408 694, EP-A-380 346. The drum of axially displaceable winding comprises at a end a threaded part. A threaded part must be provided on its support. Of the other side, reserved for his training, a layout must be provided to allow both rotational drive and induced translation by the threaded parts. All this is source of complications and additional costs. In addition, the spaces necessary for axial movement must be left free and in some realizations (CH-A-400 816) they are increasing dead spaces the size of the awning support.

Enfin, lorsqu'on souhaite disposer plusieurs stores côte à côte, par exemple pour équiper des fenêtres disposées en encorbellement et bénéficier du moteur d'entraínement de l'un deux pour l'ensemble des stores, il est quasiment impossible de réaliser une liaison cinématique simple entre les tambours et les différents stores.Finally, when you want to have several blinds side by side, for example to equip windows cantilevered and benefit from the motor one drive for all the blinds, it is almost impossible to make a connection simple kinematics between the drums and the different blinds.

L'invention a pour but d'obtenir un enroulement régulier du cordon sans déplacement axial du tambour d'enroulement.The object of the invention is to obtain a winding regular bead without axial displacement of the drum winding.

Le dispositif d'enroulement selon l'invention est caractérisé en ce que le tambour d'enroulement est monté fixe en translation dans un bâti présentant un moyen de guidage pour la section verticale du cordon et en ce que les moyens pour assurer un enroulement du cordon en spires régulières sans chevauchement sont constitués d'un écrou baladeur immobilisé en rotation et en prise avec un filet formé sur le tambour d'enroulement, ledit écrou baladeur se déplaçant entre l'extrémité du cordon fixée au tambour d'enroulement et ledit moyen de guidage du cordon.The winding device according to the invention is characterized in that the winding drum is fixedly mounted in translation in a frame having a guide means for the vertical section of the bead and in that the means for ensuring a winding of the cord in regular turns without overlapping are consisting of a sliding nut immobilized in rotation and engaged with a net formed on the drum winding, said sliding nut moving between the end of the cord attached to the winding drum and said cord guide means.

Lors de l'enroulement du cordon, les spires se forment en appui contre une face latérale de l'écrou baladeur. Si le pas de vis est égal ou supérieur au diamètre du cordon, celui-ci s'enroule alors en spires régulières sans chevauchement.When the cord is wound, the turns are formed resting against a side face of the sliding nut. If the thread pitch is equal to or greater than the diameter of the cord, it is then wound in regular turns without overlap.

Il est sans autre possible de monter plusieurs écrous baladeurs sur un même tube d'enroulement, ainsi que d'établir une liaison cinématique entre plusieurs tubes d'enroulement.No other nut can be fitted portable players on the same winding tube, as well as to establish a kinematic connection between several tubes winding.

Sur au moins la plus grande partie de la longueur de l'enroulement du cordon sur le tambour d'enroulement, le cordon passe obligatoirement d'un côté à l'autre de l'écrou baladeur. Pour des raisons de gain de place et en particulier si le tambour d'enroulement avec ses écrous baladeurs est monté dans un boítier, le cordon traverse l'écrou baladeur. Ce passage du cordon dans l'écrou baladeur peut être avantageusement utilisé pour commander une butée escamotable, comme c'est le cas dans le dispositif représenté dans le document EP-A-0 380 346. La butée escamotable peut être constituée par une simple bascule s'appuyant sur la section du cordon traversant l'écrou baladeur de telle manière qu'une tension sur le cordon a pour effet de soulever cette bascule et de dégager la butée de la contre-butée formée sur le tambour d'enroulement.Over at least most of the length of winding the cord on the winding drum, the cord must pass from one side to the other of the sliding nut. For reasons of space saving and especially if the winding drum with its sliding nuts is mounted in a case, the cord crosses the sliding nut. This passage of the cord in the sliding nut can be advantageously used to order a retractable stop, as is the case in the device shown in the document EP-A-0 380 346. The retractable stop can be formed by a simple rocker leaning on the section of the cord passing through the sliding nut in such a way that a tension on the cord has the effect of lifting this rocker and release the stopper from the counter-stopper formed on the winding drum.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.The accompanying drawing shows, by way of example, a mode of carrying out the invention.

La figure 1 est une vue partielle et en coupe axiale selon I-I de la figure 2, d'un tambour d'enroulement de store dans une position proche de l'enroulement complet.Figure 1 is a partial view in axial section according to I-I of FIG. 2, of a winding drum of blind in a position close to the winding full.

La figure 2 est une vue en coupe transversale selon II-II de la figure 1.Figure 2 is a cross-sectional view along II-II of Figure 1.

La figure 3 est une vue analogue à celle de la figure 1, store complètement déroulé. Figure 3 is a view similar to that of Figure 1, blind completely unrolled.

La figure 4 est une vue en coupe transversale selon IV-IV de la figure 3.Figure 4 is a cross-sectional view along IV-IV of figure 3.

Le dispositif d'enroulement représenté comprend un boítier ou caisson 1 de forme parallèlepipédique rectangulaire ouvert vers le haut et muni de deux flasques d'extrémité, tel que le flasque 2, supportant un moteur tubulaire 3 dont l'enveloppe 4 porte et entraíne en rotation un tambour d'enroulement 5 muni d'un filet de vis en prise avec un écrou baladeur 6 de forme carrée de côtés de longueur très légèrement inférieure à la largeur intérieure du boítier 1, de telle sorte que l'écrou baladeur 6 est immobilisé en rotation mais qu'il peut se déplacer le long du tambour d'enroulement 5 lors de la rotation de celui-ci.The winding device shown comprises a box or box 1 of rectangular parallelepipedic shape open upwards and fitted with two flanges end, such as the flange 2, supporting a motor tubular 3 whose casing 4 carries and drives in rotation of a winding drum 5 provided with a screw in engagement with a square nut 6 sides of length very slightly less than the inner width of the housing 1, so that the sliding nut 6 is immobilized in rotation but that it can move along the winding drum 5 when rotating it.

A l'extrémité du tambour d'enroulement 5 opposée au flasque 2 est fixée l'extrémité 7a d'un cordon 7. Cette fixation est assurée par tout moyen adéquat, par exemple une vis, une fente ou une bague. Le cordon 7 traverse la paroi inférieure du boítier 1, près du flasque d'extrémité 2, à travers un oeillet 8 qui sert de moyen de guidage au cordon 7 de telle sorte que celui-ci descend verticalement. Il faut en effet se représenter que l'enveloppe tubulaire 4 porte un second tambour d'enroulement analogue au tambour 5 sur lequel s'enroule un second cordon. Ces deux cordons sont fixés à une barre de charge 9 qui constitue l'extrémité inférieure du store, par exemple un store à lamelles.At the end of the winding drum 5 opposite the flange 2 is fixed the end 7a of a cord 7. This fixation is ensured by any suitable means, by example a screw, a slot or a ring. Cord 7 crosses the bottom wall of the housing 1, near the end flange 2, through an eyelet 8 which serves of guide means to the cord 7 so that it descends vertically. It is indeed necessary to represent that the tubular casing 4 carries a second winding drum similar to drum 5 on which wraps a second cord. These two cords are attached to a load bar 9 which constitutes the end bottom of the blind, for example a slatted blind.

L'écrou baladeur 6 présente, dans sa partie inférieure, une fente verticale (10), dirigée selon l'axe du tambour d'enroulement, pour le passage du cordon 7. En outre, l'écrou baladeur 6 présente un logement intérieur vertical 11 dans l'un des angles inférieurs duquel est articulée autour d'un axe horizontal 12, une butée escamotable 13 constituée d'une pièce en V dont le bras inférieur 13a traverse transversalement la fente 10 et dont l'autre bras 13b est destiné à coopérer avec deux contre-butées 14 et 15 formées chacune par une paroi radiale d'une rainure s'étendant tout le long du tambour d'enroulement 5 et diamètralement opposées. Le fond des rainures est convexe et pratiquement tangent à l'enveloppe du tambour d'enroulement. Comme on peut le voir à la figure 2, le tambour d'enroulement 5 peut toujours tourner dans le sens des aiguilles d'une montre, c'est-à-dire dans le sens d'enroulement du cordon, alors que dans l'autre sens l'extrémité du bras 13b peut venir en butée contre l'une des contre-butées 14 ou 15.The sliding nut 6 has, in its part lower, a vertical slot (10), directed along the axis of the winding drum, for the passage of the cord 7. In in addition, the sliding nut 6 has a housing vertical interior 11 in one of the lower corners which is articulated around a horizontal axis 12, a retractable stop 13 consisting of a V-shaped part, the lower arm 13a crosses transversely the slot 10 and the other arm 13b of which is intended to cooperate with two counter stops 14 and 15 formed each by a radial wall of a groove extending all along the winding drum 5 and diametrically opposite. The bottom of the grooves is convex and practically tangent to the envelope of the winding drum. As can be seen from the Figure 2, the winding drum 5 can always turn clockwise, i.e. in the winding direction of the cord, while in the other direction the end of the arm 13b can come in abutment against one of the abutments 14 or 15.

Tant qu'une tension est exercée sur le cordon 7 par le poids de la barre de charge 9, la section du cordon traversant l'écrou baladeur 6 est tendue et prend une position oblique qui soulève le bras 13a de la butée escamotable 13, ce qui a pour effet d'écarter l'extrémité du bras 13b du tambour d'enroulement 5, de telle sorte que le tambour d'enroulement 5 peut tourner dans le sens contraire des aiguilles d'une montre correspondant au déroulement du cordon, sans que la butée escamotable empêche cette rotation. Par contre, lorsque la barre d'enroulement 9 arrive au bas de l'embrasure 16 ou qu'elle rencontre un obstacle, la tension sur le cordon 7 disparaít, ce qui permet à la butée escamotable 13 de basculer sous l'effet de son propre poids, de telle sorte que son bras 13b vient en butée contre l'une des contre-butées 14 ou 15, empêchant ainsi le tambour d'enroulement de continuer de tourner et de provoquer un déroulement intempestif du cordon amenant les spires à se chevaucher et à s'emmêler.As long as tension is exerted on the cord 7 by the load bar weight 9, cord section crossing the sliding nut 6 is tight and takes a oblique position which lifts the arm 13a from the stop retractable 13, which has the effect of spreading the end of the arm 13b of the winding drum 5, so that the winding drum 5 can rotate counterclockwise corresponding to the unwinding of the cord, without the retractable stop prevents this rotation. On the other hand, when the winding bar 9 reaches the bottom of embrasure 16 or that it encounters an obstacle, the tension on the cord 7 disappears, which allows the retractable stop 13 to tilt under the effect of sound own weight, so that its arm 13b comes in abutment against one of the abutments 14 or 15, preventing the take-up drum from continuing to turn and cause an unwanted unwinding of the cord causing the turns to overlap and get tangled.

En plus des inconvénients éliminés par cette construction, cette dernière présente l'avantage d'une grande simplicité et de permettre de rejeter le point d'entrée du cordon dans le caisson 1 à la quasi-extrémité du store.In addition to the disadvantages eliminated by this construction, the latter has the advantage of great simplicity and allow to reject the point entry of the cord into the box 1 at the near end of the awning.

Le dispositif selon l'invention peut bien entendu être également utilisé avec un entraínement manuel.The device according to the invention can of course be also used with manual training.

Etant donné les brusques changements de direction du cordon 7 à l'entrée dans le caisson 1 et après avoir traversé l'écrou baladeur 6, les frottements en ces points peuvent être importants. Il est toutefois possible de réduire ces frottements par des arrondis judicieux et/ou en remplaçant l'oeillet 8 par un galet.Given the sudden changes in direction of the cord 7 at the entrance to the box 1 and after crossed the sliding nut 6, the friction in these points can be important. It is however possible to reduce this friction by rounding judicious and / or by replacing the eyelet 8 with a roller.

Le tambour d'enroulement ne doit pas être obligatoirement monté dans un caisson.The take-up drum must not be necessarily mounted in a box.

La butée escamotable pourrait avoir une autre forme et être munie d'un ressort tendant à la maintenir en position de blocage.The retractable stopper could have another shape and be provided with a spring tending to keep it in blocking position.

L'enveloppe tubulaire porte en général un second tube d'enroulement muni d'un filet de vis de sens opposé à celui du tube d'enroulement représenté et portant un second écrou baladeur se déplaçant en sens opposé à celui de l'écrou baladeur représenté.The tubular casing generally carries a second tube winding fitted with a screw thread opposite direction that of the winding tube shown and bearing a second sliding nut moving in opposite direction to that of the sliding nut shown.
