Abstract

The end of the lower part of the final blind blade (6) carries two bent stops (5), with the bend (7) facing away from the roller shaft (4). Two other stops (9) are integral to the shaft support brackets (3) and are out of plumb with the passage of the bent stops. Two guides (10) above the top end of the guide rails (2) have a convex surface, tangential to the blind surface facing the shaft. The guides ensure contact between the two sets of stops, but when retracted they allow the blind to roll past the upper stops so that it can be removed.

Description

L'invention concerne un dispositif d'arrêt pour tablier de volet roulant de type monobloc. The invention relates to a stop device for a roller shutter curtain of the monobloc type.

Parmi les volets roulants de type monobloc, se composant principalement d'un caisson préfabriqué dans lequel on a placé un arbre d'enroulement reposant par ses extrémités sur des flasques munis de paliers ou de te tons et auquel est accroché un tablier formé de lames horizontales s'articulant les unes aux autres, il existe deux façons d'arrêter la course du tablier, en fin de remontée. Among the roller shutters of the monobloc type, consisting mainly of a prefabricated box in which a winding shaft has been placed resting at its ends on flanges provided with bearings or in shades and to which is hung an apron formed of horizontal blades hinging to each other, there are two ways to stop the carriage travel, at the end of the ascent.

La plus connue consiste à placer des arrêts en forme de bouchon ou d'équerre sur la dernière lame du tablier, lesquels viennent frapper le dessous du caisson et bloquer 1 'enroulage du volet. Ce principe a l'inconvénient de laisser sortir la lame finale hors du caisson, ce qui nécessite de démonter ces arrêts pour emballer rationellement le volet, et ce qui d'autre part fait perdre du jour dans la baie, une fois ce volet installé. Un autre système consiste à placer des embouts aux extrémités de la lame finale, dont une partie émerge en débordant de chaque coté 1 'épaisseur de cette lame. Ces embouts peuvent coulisser verticalement a'à l'intérieur des rails de guidage. The best known is to place stops in the form of a stopper or square on the last blade of the deck, which strike the underside of the box and block the winding of the shutter. This principle has the disadvantage of leaving the final blade out of the box, which requires dismantling these stops to rationally pack the shutter, and which on the other hand is wasting day in the bay, once this shutter installed. Another system consists in placing end caps at the ends of the final blade, part of which emerges overflowing on each side with the thickness of this blade. These end pieces can slide vertically inside the guide rails.

 l'intérieur du caisson, des goulottes accolées aux flasques surplombent les rails. Inside the box, chutes attached to the flanges overhang the rails.

Ces goulottes servent de guides pour que le tablier descende correctement dans les rails et constituent un étranglement que les embouts de la lame finale ne peuvent franchir lors de la remontée. Il subsiste toutefois des inconvénients à ce principe.These chutes serve as guides so that the apron descends correctly into the rails and constitute a constriction that the ends of the final blade cannot cross during the ascent. There are, however, drawbacks to this principle.

Lorsque l'élément monobloc a été mis en place avec ses rails, il n'est plus possible d'extraire la lame finale, ainsi que la partie inférieure du tablier qui reste encore engagée entre les flasques. D'autre part, ce principe n'est pas adapté aux volets dont les tabliers comportent des arrêts anti-flexion. En effet, le but de ces arrêts consiste à empêcher certaines lames du tablier de s'échapper des rails de guidage sous l'effet d'une pression entrainant le cintrage des lames. Pour ce faire, des lames sont pourvues à leurs extrémités de crochets ou de rondelles, pouvant coulisser longitudinalement mais ne pouvant sertir latéralement des rails. Ces arrêts viendraient donc se bloquer dans les goulottes de la même façon que les embouts de la lame finale et empêcher le fonctionnement du volet#.When the one-piece element has been put in place with its rails, it is no longer possible to extract the final blade, as well as the lower part of the deck which still remains engaged between the flanges. On the other hand, this principle is not suitable for shutters whose decks include anti-bending stops. Indeed, the purpose of these stops is to prevent certain blades of the deck to escape from the guide rails under the effect of a pressure causing the bending of the blades. To do this, blades are provided at their ends with hooks or washers, which can slide longitudinally but cannot crimp rails laterally. These stops would therefore become blocked in the chutes in the same way as the end pieces of the final blade and prevent the shutter # from working.

Le dispositif faisant l'objet de l'invention ci-apres décrite évite ces inconvénients. Il permet à la lame finale de disparaitre entièrement dans le caisson de l'élément monobloc, en fin de remontée, il n'entrave pas le passage des arrêts anti-flexion et il permet enfin le démontage complet du tablier, même après la pose de l'élément monobloc avec ses rails. The device which is the subject of the invention described below avoids these drawbacks. It allows the final blade to disappear entirely in the box of the monobloc element, at the end of the ascent, it does not hinder the passage of the anti-bending stops and it finally allows the complete dismantling of the deck, even after the installation of the monobloc element with its rails.

On considère la figure 1. Elle représente une vue en perspective partielle d'un élément monobloc 1 avec un rail de guidage 2 attenant à un flasque 3 qui supporte ltextrémité d'un arbre d'enroulement 4. Hormis l'appareil commandant la rotation de l'arbre d'enroulement, ici poulie actionnée par une sangle, qui n'existe que d'un coté, l'autre partie du volet est symétrique par rapport à un plan orthogonal à l'axe de l'arbre d'enroulement. La description qui suit s'applique donc aussi à cette partie symétrique non représentée. We consider Figure 1. It shows a partial perspective view of a one-piece element 1 with a guide rail 2 attached to a flange 3 which supports the end of a winding shaft 4. Except for the apparatus controlling the rotation of the winding shaft, here a pulley actuated by a strap, which exists only on one side, the other part of the flap is symmetrical with respect to a plane orthogonal to the axis of the winding shaft. The following description therefore also applies to this symmetrical part, not shown.

Un arrêt coudé 5 est placé d l'extrémité de la lame finale 6, dans sa partie inférieure. Il présente, en saillie par rapport à l'épaisseur de la lame finale 6,un bec 7, pointé vers le haut et tourné du coté de la lame 6 oppose à celui orienté vers l'arbre d'enroulement 4. Le rail de guidage 2 possède un évasement interne formant une chambre 8, de façon à permettre à ce bec 7 de se mouvoir en hauteur. Une butée 9, en forme d'aile verticale, solidaire du flasque 3, est disposée à l'aplomb de cette chaz- bre 8, sur le passage du bec 7. Elle offre vers le bas une arête biseautée de forme complémentaire à celle du bec 7 pour assurer l'accrochage.Cette butée 9 est placée, par rapport à l'extrémité supérieure du rail de guidage 2, à une distance qui dépasse la hauteur du bec 7. De l'autre coté du rail de guidage 2 est placé un guide 10, pré- sentant une surface convexe surplombant l'ouverture du rail de guidage 2, et siffisas- ment éloigné du fond du rail pour ne pas entraver le passage des arrêts anti-flexion fixés aur errémités des lames du tablier. Ce guide 10 est relié au flasque 3, ou au rail de guidage 2, au moyen d'un axe-pivot 11.Il forme une boucle qui, en position normale de fonctionnement, vient enlacer un doigt 12, parallèle à l'axe-pivot 11. Il peut Outre dégagé par déformation élastique de son corps, pour basculer autour de l'axe pivot Il et ainsi écarter de la butée 9 sa surface convexe tangente au tablier. A bent stop 5 is placed at the end of the final blade 6, in its lower part. It has, projecting relative to the thickness of the final blade 6, a spout 7, pointed upwards and turned on the side of the blade 6 opposite to that oriented towards the winding shaft 4. The guide rail 2 has an internal flare forming a chamber 8, so as to allow this spout 7 to move in height. A stop 9, in the form of a vertical wing, integral with the flange 3, is disposed vertically above this chaz- ber 8, on the passage of the spout 7. It offers a bevelled edge downwards, of shape complementary to that of the spout 7 for attachment. This stop 9 is placed, relative to the upper end of the guide rail 2, at a distance which exceeds the height of the spout 7. On the other side of the guide rail 2 is placed a guide 10, having a convex surface overhanging the opening of the guide rail 2, and whistling away from the bottom of the rail so as not to obstruct the passage of the anti-bending stops fixed to the hinges of the deck slats. This guide 10 is connected to the flange 3, or to the guide rail 2, by means of a pivot axis 11. It forms a loop which, in the normal operating position, comes to embrace a finger 12, parallel to the axis- pivot 11. It can also be released by elastic deformation of its body, to tilt around the pivot axis II and thus move the stop 9 its convex surface tangent to the deck.

On considère la figure 2. Elle représente le dispositif suivant l'invention, lorsque la lame finale 6 a achevé sa course ascendante ; elle a alors quitté les rails de guidage 2 et se trouve entièrement dans le caisson de l'élément monobloc 1. We consider Figure 2. It shows the device according to the invention, when the final blade 6 has completed its upward stroke; it then left the guide rails 2 and is entirely in the box of the one-piece element 1.

La figure 3 représente le même dispositif, dans lequel on a fait basculer le guide 10, ce qui a permis d'écarter la lame finale de la butée 9, d'une distance suffisante pour que l'arrêt 5 puisse éviter la butée 9 et permettre ainsi le dégagement de la lame finale 6 hors de l'élément monobloc 1. FIG. 3 represents the same device, in which the guide 10 has been tilted, which has made it possible to separate the final blade from the stop 9, by a sufficient distance so that the stop 5 can avoid the stop 9 and thus allowing the release of the final blade 6 from the one-piece element 1.

Bien que l'invention ait été décrite à propos d'une forme de réalisation particulière, il est bien entendu qu'elle nty est nullement limitée et qu'en peut y apporter diverses modifications de forme et de combinaisons de ces divers éléments, sans pour cela s'éloigner da cadre et de l'esprit de l'invention.  Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited and that there can be various modifications of form and combinations of these various elements, without this is to depart from the framework and the spirit of the invention.
