Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention se rapporte au domaine général des volets roulants contenus dans un coffre. Elle vise plus précisément un dispositif de butée pour volet roulant ou similaire limitant l'enroulement dudit volet roulant.The present invention relates to the general field of rolling shutters contained in a trunk. It relates more specifically to a stop device for a rolling shutter or the like limiting the winding of said rolling shutter.

Etat de la techniqueState of the art

Les volets roulants comportent, de manière classique, un coffre préfabriqué contenant un arbre d'enroulement, non représenté, reposant par ses extrémités sur des paliers solidaires des flasques d'extrémité dudit coffre et auquel est accroché un tablier, non représenté, formé de lames horizontales articulées entre elles et dont les extrémités se déplacent verticalement à l'intérieur de coulisses de guidage, non représentées, solidaires d'une fenêtre d'un bâtiment associée au volet roulant ou de la maçonnerie du bâtiment entourant ladite fenêtre. Ainsi, pour remonter le volet roulant, on enroule le tablier autour de l'arbre et au contraire, pour descendre le volet roulant, on déroule le tablier.Roller shutters comprise, in a conventional manner, a prefabricated box containing a winding shaft, not shown, resting by its ends on bearings integral with the end flanges of said box and to which is hung an apron, not shown, formed of blades horizontal hinged together and whose ends move vertically inside guide rails, not shown, secured to a window of a building associated with the roller shutter or the masonry of the building surrounding said window. Thus, to raise the roller shutter, the apron is wrapped around the shaft and, on the contrary, to lower the roller shutter, the apron is unrolled.

Toutefois lors de la remontée, il est nécessaire d'arrêter la course du tablier, en fin de remontée, car il est impératif que les extrémités de la dernière lame du tablier restent dans des coulisses de guidage ou, à défaut, puissent s'y engager facilement, de sorte que le volet soit toujours guidé durant les manoeuvres successives.However, during the ascent, it is necessary to stop the travel of the apron, at the end of the ascent, because it is imperative that the ends of the last slat of the apron remain in the guide channels or, failing that, can fit there. engage easily, so that the shutter is always guided during the successive manoeuvres.

Pour ce faire, on connaît déjà des butées montées à l'extrémité latérale d'une des lames finales du tablier, ces butées évoluant à l'intérieur des coulisses et n'étant donc pas apparentes. Le brevet FR 2.804.466 donne un exemple de réalisation d'une butée cachée : cette dernière est insérée sur l'une des parois de la lame finale du volet roulant, de sorte à être en saillie par rapport à au moins une des surfaces latérales et/ou des surfaces frontales. La butée est fixée sur la lame au moyen d'un perçage ou d'un rivetage et par l'intermédiaire d'attaches de type vis, rivets ou analogues. Cette butée cachée coopère avec un butoir positionné à l'extrémité supérieure de la coulisse latérale en faisant saillie à l'intérieur de ladite coulisse par rapport à la première butée.To do this, stops are already known mounted at the lateral end of one of the final slats of the apron, these stops moving inside the wings and therefore not being visible. The patent EN 2.804.466 gives an embodiment of a hidden stopper: the latter is inserted on one of the walls of the final slat of the roller shutter, so as to project with respect to at least one of the side surfaces and/or the front surfaces . The abutment is fixed to the blade by means of a drilling or riveting and by means of fastenings of the screw, rivet or similar type. This hidden stopper cooperates with a stopper positioned at the upper end of the lateral slider projecting inside said slider relative to the first stopper.

Cet exemple de réalisation de butée est certes efficace, mais présente cependant l'inconvénient de laisser au moins une partie de la lame finale obstruer le clair du jour et donc de réduire la luminosité à l'intérieur de la pièce équipée du volet roulant.This exemplary embodiment of abutment is certainly effective, but nevertheless has the drawback of allowing at least part of the final slat to obstruct the light of day and therefore of reducing the brightness inside the room equipped with the roller shutter.

Le brevet EP0092122A2 montre un dispositif pour limiter le mouvement d'enroulement d'un volet roulant. Il montre en particulier à sa figure 13 un dispositif de butée pour un volet roulant, ledit volet roulant comportant deux coulisses de guidage pourvues à leur extrémité supérieure d'un élément de guidage et un tablier formé d'une pluralité de lames horizontales, dont une lame finale inférieure munie à chacune de ses extrémités latérales d'un logement interne, articulées entre elles et dont les extrémités latérales se déplacent verticalement à l'intérieur desdites coulisses de guidage, où ledit dispositif de butée comporte un levier pivotant autour d'un axe horizontal perpendiculaire à l'axe longitudinal dudit logement et comportant au moins une excroissance qui se déplace à l'intérieur de la coulisse de guidage associée et est apte à venir en butée contre l'élément de guidage pour bloquer la lame finale lors de la remontée du volet roulant, le levier pivotant entre une position "basse" et une position "haute" dans laquelle l'excroissance ne dépasse pas dudit bord longitudinal inférieur.The patent EP0092122A2 shows a device for limiting the winding movement of a rolling shutter. It shows in particular in its figure 13 a stop device for a roller shutter, said roller shutter comprising two guide slides provided at their upper end with a guide element and an apron formed of a plurality of horizontal blades, one of which lower final slat provided at each of its lateral ends with an internal housing, articulated between them and whose lateral ends move vertically inside said guide slides, wherein said abutment device comprises a lever pivoting about a horizontal axis perpendicular to the longitudinal axis of said housing and comprising at least one protuberance which moves inside the associated guide slide and is capable to come into abutment against the guide element to block the final slat when the roller shutter is raised, the lever pivoting between a "low" position and a "high" position in which the protrusion does not protrude from said lower longitudinal edge .

Résumé de l'inventionSummary of the invention

Le but de la présente invention est donc de proposer un dispositif de butée de volet roulant permettant de limiter la course de celui-ci lors de son enroulement d'un coffre de volet roulant tout en garantissant une ouverture maximale et une fermeture parfaite dudit volet roulant pour obtenir une luminosité ou obscurité maximale à l'intérieur de la pièce équipée du volet roulant.The object of the present invention is therefore to propose a roller shutter stopper device making it possible to limit the stroke of the latter when it is rolled up by a roller shutter box while guaranteeing maximum opening and perfect closing of said roller shutter. to obtain maximum brightness or darkness inside the room fitted with the roller shutter.

Conformément à l'invention, il est donc proposé un dispositif de butée pour un volet roulant comportant deux coulisses de guidage pourvues à leur extrémité supérieure d'un élément de guidage et un tablier formé d'une pluralité de lames horizontales, dont une lame finale inférieure munie à chacune de ses extrémités latérales d'un logement interne, articulées entre elles et dont les extrémités latérales se déplacent verticalement à l'intérieur desdites coulisses de guidage, ledit dispositif de butée est configuré pour être inséré au moins en partie dans chaque logement interne selon une direction parallèle à l'axe longitudinal de cette dernière et comporte un levier pivotant, lorsque le dispositif de butée est inséré, autour d'un axe horizontal perpendiculaire à l'axe longitudinal dudit logement et comportant au moins une excroissance qui, lorsque le dispositif de butée est inséré, se déplace à l'intérieur de la coulisse de guidage associée et est apte à venir en butée contre l'élément de guidage pour bloquer la lame finale lors de la remontée du volet roulant, le levier pivotant entre une position "basse" dans laquelle l'excroissance dépasse du bord longitudinal inférieur de ladite lame finale permettant l' effacement total de ladite lame finale lorsque ledit volet roulant est totalement ouvert, et une position "haute" dans laquelle l'excroissance ne dépasse pas dudit bord longitudinal inférieur permettant une occultation totale lorsque ledit volet roulant est totalement fermé.In accordance with the invention, there is therefore proposed an abutment device for a rolling shutter comprising two guide rails provided at their upper end with a guide element and an apron formed of a plurality of horizontal slats, including a final slat bottom provided at each of its lateral ends with an internal housing, articulated between them and whose lateral ends move vertically inside said guide slides, said stop device is configured to be inserted at least partially in each housing internal in a direction parallel to the longitudinal axis of the latter and comprises a pivoting lever, when the abutment device is inserted, around a horizontal axis perpendicular to the longitudinal axis of said housing and comprising at least one protrusion which, when the abutment device is inserted, moves inside the associated guide rail and is capable of coming into abutment against the guide element to block the final slat when the roller shutter is raised, the lever pivoting between a "low" position in which the protrusion protrudes from the lower longitudinal edge of said final slat allowing the total obliteration of said final slat when said roller shutter is completely open, and a "high" position in which the protrusion does not protrude from said lower longitudinal edge allowing total concealment when said roller shutter is completely closed.

Chaque levier comprend de préférence au moins une butée apte à venir en appui contre la paroi interne du logement de ladite lame finale, lorsque ledit levier est en position "basse".Each lever preferably comprises at least one abutment able to bear against the internal wall of the housing of said final slat, when said lever is in the "down" position.

Selon un mode de réalisation avantageux, chaque levier est en forme globale de L et comprend une première aile globalement horizontale et une deuxième aile issue de l'une des extrémités de ladite première aile et s'étendant vers le bas sensiblement perpendiculairement à cette dernière, ledit levier pivotant au niveau de l'extrémité libre de sa première aile et ladite excroissance étant solidaire de l'extrémité libre de ladite deuxième aile et s'étendant de part et d'autre de cette dernière selon une direction parallèle à l'axe de pivotement du levier.According to an advantageous embodiment, each lever is in the overall shape of an L and comprises a first generally horizontal wing and a second wing coming from one of the ends of said first wing and extending downwards substantially perpendicular to the latter, said lever pivoting at the free end of its first wing and said protuberance being integral with the free end of said second wing and extending on either side of the latter in a direction parallel to the pivot axis of the lever.

Chaque levier comprend avantageusement deux butées disposées, de façon diagonalement opposée, respectivement le long du bord inférieur et supérieur de sa première aile.Each lever advantageously comprises two stops arranged, diagonally opposite, respectively along the lower and upper edge of its first wing.

Description des modes de réalisationDescription of embodiments

En référence aux figures 1 à 7, le dispositif de butée 1 mobile selon l'invention est prévu pour un volet roulant 2 ou similaire comportant un tablier 3 formé d'une pluralité de lames horizontales comprenant un logement interne en forme globale de tube creux, dont une lame finale 4 inférieure, articulées entre elles et dont les extrémités latérales se déplacent verticalement à l'intérieur de coulisses de guidage 5 solidaires de la fenêtre associée (non représentée) au volet roulant 2 ou du génie civil entourant ladite fenêtre, ledit tablier 3 étant accroché et mis en mouvement par un arbre d'enroulement reposant par ses extrémités sur des paliers (non représentés) solidaires, de manière classique, des flasques d'extrémités d'un coffre non représenté. Ainsi avec une telle configuration, on comprend bien que, pour fermer le volet roulant 2, on fait remonter le tablier 3 en l'enroulant autour de l'arbre d'enroulement et au contraire, pour ouvrir le volet roulant 2, on fait descendre le tablier 3 en le déroulant.With reference to figures 1 to 7 , the movable stop device 1 according to the invention is provided for a roller shutter 2 or the like comprising an apron 3 formed of a plurality of horizontal slats comprising an internal housing in the overall shape of a hollow tube, including a lower final slat 4, hinged together and whose lateral ends move vertically inside guide rails 5 integral with the window associated (not shown) with the roller shutter 2 or with the civil engineering surrounding said window, said apron 3 being hooked and set in motion by a winding shaft resting at its ends on bearings (not shown) integral, in a conventional manner, with the end plates of a box, not shown. Thus with such a configuration, it is clear that, to close the roller shutter 2, the apron 3 is brought up by winding it around the winding shaft and, on the contrary, to open the roller shutter 2, apron 3 by unrolling it.

Chaque coulisse de guidage 5 est avantageusement munie à son extrémité supérieure d'un élément de guidage 6, communément appelé tulipe, servant à guider les lames du tablier 3 lors des manoeuvres successives d'enroulement et de déroulement dudit tablier 3 autour de l'arbre d'enroulement.Each guide slide 5 is advantageously provided at its upper end with a guide element 6, commonly called a tulip, serving to guide the blades of the apron 3 during the successive maneuvers of winding and unwinding of said apron 3 around the shaft. winding.

Dans la présente demande, le volet roulant 2 décrit est apte à être déroulé suivant un plan vertical le long des coulisses de guidage 5 verticales. Il va de soi que le volet roulant 2 pourra également être déroulé suivant un plan plus ou moins incliné par rapport à la verticale voire horizontal, sans sortir de la présente invention, les termes "horizontal", "vertical", "inférieur" ou encore "supérieur" seront alors à adapter à l'inclinaison du plan de déroulement dudit volet roulant 2.In the present application, the roller shutter 2 described is adapted to be unrolled along a vertical plane along the guide rails 5 vertical. It goes without saying that the roller shutter 2 can also be unrolled along a more or less inclined plane with respect to the vertical or even horizontal, without departing from the present invention, the terms "horizontal", "vertical", "lower" or even "upper" will then have to be adapted to the inclination of the unwinding plane of said roller shutter 2.

En référence à la figure 1, la lame finale 4 comprend un dispositif de butée 1 mobile selon l'invention à chacune de ses extrémités longitudinales, chaque dispositif de butée 1 étant inséré au moins en partie dans un logement 41 interne (Cf. figure 5) de ladite lame finale 4 selon une direction parallèle à l'axe longitudinal de cette dernière.With reference to the figure 1 , the final slat 4 comprises a movable abutment device 1 according to the invention at each of its longitudinal ends, each abutment device 1 being inserted at least partially into an internal housing 41 (Cf. figure 5 ) of said final slat 4 in a direction parallel to the longitudinal axis of the latter.

En référence aux figures 2 à 7, chaque dispositif de butée 1 mobile selon l'invention comporte un levier 10 en forme globale de L monté pivotant, avantageusement sur un support 20, autour d'un axe 11 horizontal perpendiculaire à l'axe longitudinal du logement 41 de la lame finale 4 (Cf. figures 3 et 5), lorsque ledit dispositif de butée 1 est inséré dans ce dernier. Ainsi, ledit levier 10 comprend une première aile 12 globalement horizontale, une deuxième aile 13 issue de l'une des extrémités de ladite première aile 12 et s'étendant vers le bas sensiblement perpendiculairement à cette dernière, et une excroissance 14 solidaire de l'extrémité libre de ladite deuxième aile 13 et s'étendant avantageusement de part et d'autre de cette dernière selon une direction parallèle à l'axe 11 de pivotement du levier 10. Le levier 10 est monté pivotant sur le support 20 autour de l'axe 11 au niveau de l'extrémité libre de sa première aile 12, de manière à ce qu'un pivotement du levier 10 autour de l'axe 11 entraine un déplacement de l'excroissance 14 de bas en haut ou inversement. On comprend bien que ce déplacement de l'excroissance 14 de bas en haut ou inversement serait impossible, si ledit levier 10 pivotait autour d'un axe parallèle à l'axe longitudinal du logement 41 de la lame finale 4, comme cela est le cas dans certains dispositifs de l'Etat de la Technique.With reference to figures 2 to 7 , each mobile abutment device 1 according to the invention comprises a lever 10 in the overall shape of an L pivotally mounted, advantageously on a support 20, about a horizontal axis 11 perpendicular to the longitudinal axis of the housing 41 of the final slat 4 (see figure 3 And 5 ), when said abutment device 1 is inserted into it. Thus, said lever 10 comprises a first generally horizontal wing 12, a second wing 13 coming from one of the ends of said first wing 12 and extending downwards substantially perpendicular to the latter, and a protrusion 14 integral with the free end of said second wing 13 and advantageously extending on either side of the latter in a direction parallel to the pivot axis 11 of the lever 10. The lever 10 is pivotally mounted on the support 20 around the axis 11 at the free end of its first wing 12, so that a pivoting of the lever 10 around the axis 11 causes a movement of the protrusion 14 from bottom to top or vice versa. It is understood that this movement of the protrusion 14 from bottom to top or vice versa would be impossible, if said lever 10 pivoted around an axis parallel to the longitudinal axis of the housing 41 of the final slat 4, as is the case in certain state-of-the-art devices.

On désigne ici par "globalement horizontale" et "sensiblement perpendiculaire" des éléments ou parties d'éléments faisant respectivement un angle de 0° +/-20° par rapport à l'horizontale et un angle de 90° +/-20° par rapport à d'éléments ou parties d'éléments.The term "globally horizontal" and "substantially perpendicular" denotes elements or parts of elements respectively making an angle of 0° +/-20° with respect to the horizontal and an angle of 90° +/-20° with respect to relation to elements or parts of elements.

Ledit dispositif de butée 1 est configuré pour que, lorsqu'il est inséré dans le logement 41 de la lame finale 4, le levier 10 pivote autour de l'axe 11 entre :

  • une position "basse" dans laquelle l'excroissance 14 dépasse avantageusement du bord longitudinal inférieur de la lame finale 4 (Cf. figure 7) permettant, lorsque le volet roulant 2 est totalement ouvert, un effacement total de ladite lame finale 4 et donc une luminosité maximale à l'intérieur de la pièce équipée dudit volet roulant 2, et
  • une position "haute" dans laquelle l'excroissance 14 ne dépasse avantageusement pas du bord longitudinal inférieur de ladite lame finale 4 (Cf. figure 5) permettant, lorsque le volet roulant 2 est totalement fermé, une occultation totale de la fenêtre associée et donc une obscurité maximale à l'intérieur de la pièce équipée dudit volet roulant 2, ladite excroissance 14 étant à l'extérieur de la lame finale 4 et se déplaçant à l'intérieur de la coulisse de guidage 5 associée.
Said abutment device 1 is configured so that, when it is inserted into the housing 41 of the final slat 4, the lever 10 pivots around the axis 11 between:
  • a "low" position in which the protrusion 14 advantageously protrudes from the lower longitudinal edge of the final slat 4 (Cf. figure 7 ) allowing, when the roller shutter 2 is completely open, total obliteration of said final slat 4 and therefore maximum brightness inside the room equipped with said roller shutter 2, and
  • a "high" position in which the protrusion 14 advantageously does not protrude from the lower longitudinal edge of said final slat 4 (Cf. figure 5 ) allowing, when the roller shutter 2 is completely closed, total concealment of the associated window and therefore maximum darkness inside the room equipped with said roller shutter 2, said protrusion 14 being outside the final slat 4 and moving inside the associated guide slide 5.

Pour cela, le levier 10 comprend au moins une butée apte à venir en appui contre la paroi interne du logement 41 de ladite lame finale 4, lorsque ledit levier 10 est en position "basse" (Cf. figure 7). Le levier 10 comprend avantageusement deux butées 15,16 disposées, de façon diagonalement opposée, respectivement le long du bord inférieur et supérieur de la première aile 12. Avec cette configuration, les efforts et contraintes mécaniques ne sont pas repris par l'axe 11 de pivotement, mais par les butées 15,16 du levier 10 qui viennent en appui sur la paroi interne du logement 41 de ladite lame finale 4, qui est classiquement réalisée en aluminium.For this, the lever 10 comprises at least one stop capable of coming to bear against the internal wall of the housing 41 of the said final slat 4, when the said lever 10 is in the "down" position (Cf. figure 7 ). The lever 10 advantageously comprises two stops 15,16 arranged, diagonally opposite, respectively along the lower and upper edge of the first wing 12. With this configuration, the forces and mechanical stresses are not taken up by the pivot axis 11, but by the stops 15,16 of the lever 10 which come to rest on the internal wall of the housing 41 of said final slat 4, which is conventionally made of aluminium.

En référence aux figures 3 et 4, selon un mode de réalisation avantageux, ledit support 20 comporte deux parties 21, 22 assemblées entre elles par l'intermédiaire notamment de deux pions 23. Ainsi, le support 20 se compose d'une première partie 21 du support 20 présentant un évidement 24 de sorte que sa section transversale soit en forme globale de C, et d'une deuxième partie 22 du support 20 étant une plaque assemblée en appui contre ladite première partie 21 de manière à refermer l'évidement 24. Avec cette configuration avantageuse, le levier 10 est en partie disposé à l'intérieur du support 20 dans l'évidement 24, ce dernier étant dimensionné pour permettre le pivotement du levier 10 autour de l'axe 11 entre sa position "basse" et sa position "haute" ou inversement.With reference to figures 3 and 4 , according to an advantageous embodiment, said support 20 comprises two parts 21, 22 assembled together by means in particular of two pins 23. Thus, the support 20 consists of a first part 21 of the support 20 having a recess 24 so that its cross section is in the overall shape of a C, and of a second part 22 of the support 20 being an assembled plate bearing against said first part 21 so as to close the recess 24. With this advantageous configuration, the lever 10 is partly disposed inside the support 20 in the recess 24, the latter being dimensioned to allow the pivoting of the lever 10 around the axis 11 between its "low" position and its "high" position or vice versa.

Par ailleurs, la première partie 21 du support 20 comporte des découpes 25,26 pour permettre, lorsque ledit levier 10 est en position "basse", le passage des butées 15,16 et leur appui contre la paroi interne du logement 41 de ladite lame finale 4.Furthermore, the first part 21 of the support 20 comprises cutouts 25,26 to allow, when said lever 10 is in the "down" position, the passage of the stops 15,16 and their support against the internal wall of the housing 41 of said blade final 4.

Le support 20 du dispositif de butée 1 comporte en outre des moyens de rappel tendant à ramener le levier 10 dans sa position "haute". Ces moyens de rappel sont avantageusement une languette 27 flexible élastiquement solidaire de la première partie 21 dudit support 20. Ces moyens de rappel permettent un bon coulissement de la lame finale 4 dans les coulisses de guidage 5, car, lorsque que chaque levier 10 est dans sa position "haute", la première aile 12 de ce dernier est sensiblement horizontale et l'excroissance 14 associée est alors parfaitement centré par rapport à la coulisse de guidage 5 associée et coulisse facilement dans cette dernière (Cf. figure 5). En revanche, lorsque que chaque levier 10 est dans sa position "basse", la première aile 12 de ce dernier est légèrement inclinée et l'excroissance 14 associée est décalé vers le milieu de la lame finale 4 du fait du pivotement du levier 10 autour de son axe 11et n'est alors plus parfaitement centré par rapport à la coulisse de guidage 5 associée, le coulissement de ladite excroissance 14 n'est alors plus optimal (Cf. figure 7).The support 20 of the abutment device 1 further comprises return means tending to return the lever 10 to its "high" position. These return means are advantageously a flexible tab 27 elastically integral with the first part 21 of said support 20. These return means allow good sliding of the final slat 4 in the guide slides 5, because, when each lever 10 is in its "high" position, the first wing 12 of the latter is substantially horizontal and the associated protrusion 14 is then perfectly centered with respect to the associated guide slide 5 and slides easily in the latter (Cf. figure 5 ). On the other hand, when each lever 10 is in its "down" position, the first wing 12 of the latter is slightly inclined and the associated protrusion 14 is shifted towards the middle of the final blade 4 due to the pivoting of the lever 10 around of its axis 11et is then no longer perfectly centered with respect to the associated guide slide 5, the sliding of said protrusion 14 is then no longer optimal (Cf. figure 7 ).

L'homme du Métier n'aura aucune difficulté pour dimensionner le levier 10 afin de limiter ce phénomène de décalage de l'excroissance 14 vers le milieu de la lame finale 4, en allongeant la première aile 12 de ce dernier de manière à déplacer la position de l'axe 11 pour agrandir le rayon de pivotement dudit levier 10.The person skilled in the art will have no difficulty in sizing the lever 10 in order to limit this phenomenon of shifting of the protrusion 14 towards the middle of the final slat 4, by extending the first wing 12 of the latter so as to move the position of axis 11 to enlarge the radius of pivoting of said lever 10.

En référence aux figures 5 à 7, le dispositif de butée 1 selon l'invention permet le fonctionnement suivant du volet roulant 2.With reference to figures 5 to 7 , the stop device 1 according to the invention allows the following operation of the roller shutter 2.

Ainsi, en référence à la figure 5, lorsque le volet roulant 2 est fermé, le levier 10 est maintenu en position "haute" par les moyens de rappel du support 20, l'excroissance 14 associée ne dépasse pas du bord longitudinal inférieur de ladite lame finale 4, cette dernière étant parfaitement en appui sur le bord inférieur de la fenêtre ou du génie civil entourant cette dernière de manière à occulter totalement ladite fenêtre pour obtenir une obscurité maximale à l'intérieur de la pièce équipée dudit volet roulant 2. Toutefois, on notera qu'en l'absence de moyens rappel, le levier 10 reviendrait naturellement dans sa position "haute" par l'intermédiaire de l'excroissance 14 associée prenant appui sur le bord inférieur de la fenêtre ou du génie civil entourant cette dernière.So, with reference to the figure 5 , when the roller shutter 2 is closed, the lever 10 is held in the "high" position by the return means of the support 20, the associated protrusion 14 does not protrude from the lower longitudinal edge of said final slat 4, the latter being perfectly resting on the lower edge of the window or of the civil engineering surrounding the latter so as to completely obscure said window to obtain maximum darkness inside the room equipped with said roller shutter 2. However, it will be noted that in the absence of return means, the lever 10 would naturally return to its "high" position via the associated protrusion 14 resting on the lower edge of the window or of the civil engineering surrounding the latter.

Lorsque le volet roulant 2 commence à s'ouvrir, le levier 10 est maintenu en position "haute" par les moyens de rappel du support 20, l'excroissance 14 est parfaitement centrée dans la coulisse de guidage 5 et le volet roulant 2 continue à s'ouvrir normalement.When the roller shutter 2 begins to open, the lever 10 is held in the "high" position by the return means of the support 20, the protrusion 14 is perfectly centered in the guide slide 5 and the roller shutter 2 continues to open normally.

Enfin, en référence aux figures 6 et 7, lorsque que le volet roulant 2 est presque totalement ouvert, l'excroissance 14 du dispositif de butée 1 vient en contact avec la face inférieure de l'élément de guidage 6 de la coulisse de guidage 5 associée, le levier 10 commence alors à pivoter autour de son axe 11 (Cf. figure 6), le volet roulant 2 continue ensuite à s'ouvrir jusqu'à ce que ledit levier 10 vienne dans sa position "basse" (Cf. figure 7), le volet roulant 2 s'arrête car le levier 10 est bloqué notamment par sa ou ses butée(s) 15,16 en appui contre la paroi interne du logement 41 de sa lame finale 4. Dans cette position, la lame finale 4 est allée au-delà de la face inférieure de l'élément de guidage 6 de la coulisse de guidage 5 associée, et garantit alors une ouverture maximale dudit volet roulant 2 pour obtenir une luminosité maximale à l'intérieur de la pièce équipée de ce dernier.Finally, with reference to figures 6 and 7 , when the roller shutter 2 is almost completely open, the protrusion 14 of the stop device 1 comes into contact with the underside of the guide element 6 of the associated guide slide 5, the lever 10 then begins to pivot around its axis 11 (Cf. figure 6 ), the roller shutter 2 then continues to open until said lever 10 comes into its "down" position (Cf. figure 7 ), the roller shutter 2 stops because the lever 10 is blocked in particular by its stop(s) 15,16 resting against the internal wall of the housing 41 of its final slat 4. In this position, the final slat 4 has gone beyond the underside of the guide element 6 of the associated guide slide 5, and then guarantees maximum opening of said roller shutter 2 to obtain maximum brightness inside the room equipped with the latter .

Lorsque le volet roulant 2 se referme, le levier 10 du dispositif de butée 1 est ramené en position "haute" par les moyens de rappel du support 20, l'excroissance 14 est alors parfaitement centrée dans la coulisse de guidage 5 pour ne pas gêner le mouvement dudit volet roulant 2.When the roller shutter 2 closes, the lever 10 of the stop device 1 is returned to the "up" position by the return means of the support 20, the protrusion 14 is then perfectly centered in the guide slide 5 so as not to interfere the movement of said rolling shutter 2.

On comprend bien que le dispositif de butée 1 selon l'invention est particulièrement intéressant, car il n'est pas nécessaire de modifier la coulisse de guidage 5 et/ou l'élément de guidage 6 associé pour obtenir une ouverture maximale dudit volet roulant 2 et une luminosité maximale à l'intérieur de la pièce équipée dudit volet roulant 2.It is well understood that the abutment device 1 according to the invention is particularly interesting, because it is not necessary to modify the guide slide 5 and/or the associated guide element 6 to obtain maximum opening of said roller shutter 2 and maximum brightness inside the room equipped with said roller shutter 2.

Le dispositif de butée 1 d'un volet roulant ou similaire selon l'invention trouve une application particulière pour équiper une fenêtre d'un bâtiment ou d'une maison d'habitation.The stop device 1 of a rolling shutter or the like according to the invention finds a particular application for equipping a window of a building or a dwelling house.

Enfin, il va de soi que les exemples de dispositif de butée 1 conformes à l'invention qui viennent d'être décrits ne sont que des illustrations particulières, en aucun cas limitatives de l'invention.Finally, it goes without saying that the examples of abutment device 1 in accordance with the invention which have just been described are only specific illustrations, in no way limiting the invention.
