Description

L'invention est relative à un dispositif à volet destiné notamment à la fermeture d'une baie ou autre ouverture, par le déplacement du volet par rapport à des chemins de guidage.The invention relates to a flap device intended in particular for closing a bay or other opening, by moving the flap relative to guideways.

Les documents WO95/30064 , EP 0 272 733 et EP 0 587 586 décrivent un dispositif de fermeture dans lequel les bords latéraux du volet sont guidés dans des chemins de guidage. Lorsqu'une certaine force de traction transversale à la direction longitudinale est exercée sur les bords du volet, celui-ci se dégage des chemins de guidage. Dans ce type de dispositif, les bords latéraux du volet peuvent être endommagés lors du dégagement et doivent être réparés, ce qui entraîne des frais importants de démontage. De plus, le déplacement du volet dans les chemins de guidage produit du bruit.The documents WO95 / 30064 , EP 0 272 733 and EP 0 587 586 disclose a closure device in which the side edges of the flap are guided in guideways. When a certain traction force transverse to the longitudinal direction is exerted on the edges of the flap, it is disengaged from the guideways. In this type of device, the side edges of the flap can be damaged during release and must be repaired, which entails significant disassembly costs. In addition, moving the flap in the guideways produces noise.

Un des buts essentiels de la présente invention est de présenter un dispositif qui permet de remédier aux inconvénients précités, tout en étant d'une conception et construction simples et d'une parfaite fiabilité. Ainsi, le dispositif, suivant l'invention, est sujet à une usure très réduite par rapport aux dispositifs de l'art antérieur et occasionne beaucoup moins de bruit. Il y a également lieu de noter que le frottement dans les chemins de guidage lors du déplacement du volet est relativement faible, de sorte que le dispositif, suivant l'invention, consomme beaucoup moins d'énergie.One of the essential aims of the present invention is to provide a device that overcomes the aforementioned drawbacks, while being of a simple design and construction and a perfect reliability. Thus, the device according to the invention is subject to very little wear compared to the devices of the prior art and causes much less noise. It should also be noted that the friction in the guideways during movement of the flap is relatively low, so that the device according to the invention consumes much less energy.

A cet effet, suivant l'invention, des moyens de transmission sont intercallés entre les bords latéraux du volet et les chemins de guidage et sont fixés aux bords latéraux du volet d'une manière telle que dès qu'une certaine force de traction transversale à la direction longitudinale des chemins de guidage est exercée sur les bords latéraux du volet par rapport aux moyens de transmission, ces bords sont séparés partiellement de ces derniers.For this purpose, according to the invention, transmission means are intercalated between the lateral edges of the flap and the guideways and are fixed to the lateral edges of the flap in such a way that as soon as a certain transverse traction force the longitudinal direction of the guideways is exerted on the lateral edges of the flap relative to the transmission means, these edges are partially separated from the latter.

Avantageusement, les moyens de transmission sont fixés aux bords latéraux du volet par des moyens d'accrochage.Advantageously, the transmission means are attached to the lateral edges of the flap by means of attachment.

Suivant une forme de réalisation particulière de l'invention, le volet présente des bords latéraux saillant par rapport au plan du volet, ces bords étant enserrés par lesdits moyens de transmission.According to a particular embodiment of the invention, the flap has lateral edges projecting from the plane of the flap, these edges being clamped by said transmission means.

Suivant une forme de réalisation particulièrement avantageuse de l'invention, les moyens de transmission présentent une succession d'évidements espacés suivant la direction de déplacement du volet qui coopèrent avec des moyens d'entraînement permettant le déplacement du volet suivant la direction des chemins de guidage.According to a particularly advantageous embodiment of the invention, the transmission means have a series of recesses spaced in the direction of movement of the flap which cooperate with drive means for moving the flap along the direction of the guideways. .

Les moyens d'entraînement comprennent de préférence une roue dentée dont les dents sont espacées l'une de l'autre afin de pouvoir coopérer avec les évidements des moyens de transmission.The drive means preferably comprise a toothed wheel whose teeth are spaced from each other in order to cooperate with the recesses of the transmission means.

Suivant une forme de réalisation préférentielle de l'invention, des moyens de réintroduction sont prévus afin de rétablir la liaison entre les moyens de transmission et le volet lors de l'ouverture ou la fermeture du volet si ce dernier a été séparé des moyens de transmission, ces moyens de réintroduction comprenant des organes pour exercer une force de pression sur les bords latéraux du volet.According to a preferred embodiment of the invention, reintroduction means are provided in order to restore the connection between the transmission means and the flap when opening or closing the shutter if it has been separated from the transmission means. these reintroduction means comprising members for exerting a pressing force on the lateral edges of the flap.

Dans les différentes figures, les mêmes chiffres de référence se rapportent aux mêmes éléments ou à des éléments analogues.In the different figures, the same reference numerals refer to the same elements or similar elements.

Le dispositif, suivant l'invention, comme représenté aux figures 1 et 2, comprend un volet 1 pouvant se déplacer, entre une position de fermeture et une position d'ouverture, dans la direction de la flèche 2 et destiné à la fermeture d'une baie 3 ou toute ouverture ou passage dans une paroi 4. Dans les figures 1 et 2, le dispositif est représenté dans sa position de fermeture avec le bord libre 16 du volet 1 contre le sol 17.The device, according to the invention, as shown in figures 1 and 2 , comprises a shutter 1 that can move, between a closed position and an open position, in the direction of the arrow 2 and intended for the closure of a bay 3 or any opening or passage in a wall 4. In figures 1 and 2 , the device is shown in its closed position with the free edge 16 of the shutter 1 against the ground 17.

Par le mot "volet", il y a lieu de comprendre, dans le cadre de la présente invention, tout élément au moins partiellement souple, flexible, rigide ou semi-rigide, tel qu'une bâche, une bande en matière plastique, un assemblage de lamelles articulées, une grille, etc....By the word "shutter", it should be understood, in the context of the present invention, any element that is at least partially flexible, flexible, rigid or semi-rigid, such as a tarpaulin, a plastic strip, a assembly of articulated slats, a grid, etc.

Il y a, toutefois, lieu de noter qu'une préférence prononcée est donnée aux volets souples formés par une bâche. Ainsi, les figures concernent un volet constitué d'une bâche 1 dont les bords latéraux 9 et 10 sont formés par une bandelette réalisée éventuellement en une autre matière qui est, par exemple, uniquement flexible dans sa direction longitudinale. Cette bandelette est fixée à la bâche par collage, soudage ou tout autre moyen.It should be noted, however, that a pronounced preference is given to the flexible shutters formed by a tarpaulin. Thus, the figures relate to a flap consisting of a tarpaulin 1 whose side edges 9 and 10 are formed by a strip optionally made of another material which is, for example, only flexible in its longitudinal direction. This strip is fixed to the sheet by gluing, welding or any other means.

Le volet 1 est guidé par des moyens de transmission 5 et 6 dans des chemins de guidage 7 et 8 qui présentent une partie verticale de part et d'autre de la baie 3 et une partie s'étendant sensiblement horizontalement à un niveau situé au-dessus de la baie 3. Lors de l'ouverture du volet 1, ce dernier est déplacé de la partie verticale des chemins de guidage 7 et 8 jusqu'à la partie horizontale afin de permettre l'accès par la baie 3. Les chemins de guidages 7 et 8 sont fixés à la paroi 4 par des cornières 15.The shutter 1 is guided by transmission means 5 and 6 in guideways 7 and 8 which have a vertical part on either side of the bay 3 and a portion extending substantially horizontally to a level situated on the 3. When opening the shutter 1, the latter is moved from the vertical part of the guide tracks 7 and 8 to the horizontal part in order to allow access through the bay 3. The paths of 7 and 8 are attached to the wall 4 by angles 15.

Les moyens de transmission 5 et 6 coopèrent avec des moyens d'entraînement afin de pouvoir déplacer le volet 1 dans la direction de la flèche 2. Ces moyens d'entraînement comprennent deux roues dentées 35, disposées à proximité des deux bords latéraux 9 et 10 du volet 1, avec un axe de rotation 12 commun. Ce dernier est actionné par un moteur électrique 13. Pour fermer la baie 3 par le volet 1 les roues dentées subissent une rotation dans la direction de la flèche 18.The transmission means 5 and 6 cooperate with drive means in order to be able to move the flap 1 in the direction of the arrow 2. These drive means comprise two toothed wheels 35 arranged near the two lateral edges 9 and 10. flap 1, with a common axis of rotation 12. The latter is actuated by an electric motor 13. To close the bay 3 by the flap 1 the toothed wheels are rotated in the direction of the arrow 18.

La figure 3 représente une forme de réalisation particulière des moyens de transmission 5 ou 6. Ces derniers comprennent une bande métallique flexible 19 continue pourvue de moyens d'accrochage par lesquels la bande métallique 19 est fixée aux bords latéraux 9 et 10 du volet 1. La bande métallique 19 s'étend sur toute la longueur du volet 1 dans le plan de ce dernier. Les moyens d'accrochage présentent une succession de pinces 20 qui sont indépendantes les unes par rapport aux autres.The figure 3 represents a particular embodiment of the transmission means 5 or 6. These comprise a continuous flexible metal strip 19 provided with hooking means by which the metal strip 19 is fixed to the side edges 9 and 10 of the flap 1. The metal strip 19 extends over the entire length of the flap 1 in the plane of the latter. The attachment means have a succession of clamps 20 which are independent of each other.

Pour que lesdites pinces 20 puissent bien être fixées aux bords latéraux 9 et 10 du volet 1, ceux-ci sont saillants par rapport au plan du volet 1. En particulier, ces bords latéraux 9 et 10 sont pourvus d'un bourrelet 21 sur lequel s'adaptent les pinces 20. De plus, un épaississement 22 est prévu aux bords latéraux 9 et 10, à proximité du bourrelet 21 et de part et d'autre du plan du volet 1, qui présente à ses deux cotés des faces 23 et 24 perpendiculaires par rapport au plan du volet 1. La fonction des faces 23 et 24 sera décrite ci-après.So that said clamps 20 can be fixed to the side edges 9 and 10 of the flap 1, they are projecting relative to the plane of the flap 1. In particular, these side edges 9 and 10 are provided with a bead 21 on which In addition, a thickening 22 is provided at the side edges 9 and 10, near the bead 21 and on either side of the plane of the flap 1, which has on both sides faces 23 and 24 perpendicular to the plane of the flap 1. The function of the faces 23 and 24 will be described below.

Les pinces 20 sont constituées de deux lamelles métalliques 25 et 26 montées de part et d'autre de la bande 19 au moyen de rivets. Ces lamelles 25 et 26 présentent une partie courbée 27, respectivement 28, qui s'étend au-delà du bord de la bande 19, de sorte que le bourrelet 21 est enserré entre ces lamelles. Afin de pouvoir dégager le volet 1 par rapport à la bande métallique 19 et de pouvoir fixer le volet 1 à nouveau à cette dernière, les pinces 20 peuvent être déformées élastiquement.The clamps 20 consist of two metal strips 25 and 26 mounted on either side of the strip 19 by means of rivets. These strips 25 and 26 have a curved portion 27, respectively 28, which extends beyond the edge of the strip 19, so that the bead 21 is sandwiched between these strips. In order to be able to disengage the shutter 1 with respect to the metal strip 19 and to be able to fix the shutter 1 again to the latter, the clamps 20 can be deformed elastically.

A l'extrémité des lamelles 25 et 26, opposée à celle présentant les parties courbées 27 et 28, des moyens de guidage sont prévus afin de permettre le déplacement des moyens de transmission, c.à.d. la bande métallique 19, suivant la direction longitudinale des chemins de guidage 7 et 8. Ces moyens de guidage comprennent, dans la forme de réalisation de l'invention comme représentée à la figure 3, des saillies de guidage 29 et 30. Lesdites saillies 29 et 30 sont constituées par les extrémités des lamelles 25 et 26 pliées à angle droit par rapport au plan de la bande métallique 19.At the end of the lamellae 25 and 26, opposite to that having the curved portions 27 and 28, guiding means are provided to allow the movement of the transmission means, i.e. the metal strip 19, in the longitudinal direction of the guideways 7 and 8. These guide means comprise, in the embodiment of the invention as shown in FIG. figure 3 , guiding projections 29 and 30. Said projections 29 and 30 are constituted by the ends of the strips 25 and 26 bent at right angles to the plane of the metal strip 19.

Les saillies 29 et 30 sont guidées dans une fente sensiblement continue dans les chemins de guidage 7 et 8, formant ainsi une glissière suivant la direction longitudinale de ces derniers.The projections 29 and 30 are guided in a substantially continuous slot in the guideways 7 and 8, thereby forming a slide in the longitudinal direction thereof.

La bande métallique 19 présente, le long de son bord opposé à celui dirigé vers le volet 1, une succession d'évidements espacés 31. L'espacement et les dimensions des évidements 31 sont tels à permettre à la roue dentée 35 de s'engrener avec la bande métallique 19 et de déplacer cette dernière suivant une direction parallèle aux chemins de guidage 7 et 8.The metal strip 19 has, along its edge opposite to that directed towards the flap 1, a succession of spaced recesses 31. The spacing and the dimensions of the recesses 31 are such as to allow the toothed wheel 35 to mesh with the metal strip 19 and move the latter in a direction parallel to the guideways 7 and 8.

Dans la figure 4 est représentée une variante des moyens de transmission 5 ou 6 de la figure 3. Ces moyens de transmission 5 ou 6 sont pourvus de moyens d'accrochage constitués d'une succession de pinces 20 comprenant deux lamelles 25 et 26 situées symétriquement de part et d'autre de la bande métallique 19 à laquelle elles sont fixées par soudure ou par collage. Une partie de chacune des lamelles 25 et 26 s'étend au-delà du bord de la bande métallique 19 et est pliée en forme de crochet de manière à permettre d'enserrer le bourrelet 21. Le bout 34 des lamelles 25 et 26 est replié vers l'extérieur, comme dans la forme de réalisation représentée à la figure 3, afin de pouvoir aisément réintroduire le bourrelet 21 du volet 1 entre les pinces 20 lorsque ce dernier s'est dégagé par rapport à ces pinces 20.In the figure 4 is represented a variant of the transmission means 5 or 6 of the figure 3 . These transmission means 5 or 6 are provided with attachment means consisting of a succession of clamps 20 comprising two strips 25 and 26 located symmetrically on either side of the metal strip 19 to which they are fixed by welding or by bonding. A portion of each of the lamellae 25 and 26 extends beyond the edge of the metal strip 19 and is folded in the form of a hook so as to make it possible to grip the bead 21. The end 34 of the lamellae 25 and 26 is folded outwardly, as in the embodiment shown in FIG. figure 3 , in order to easily reintroduce the bead 21 of the shutter 1 between the clamps 20 when the latter has disengaged with respect to these clamps 20.

Les bandelettes, formant les bords latéraux du volet 9 et 10, sont pourvues d'un épaississement 22 s'étendant de part et d'autre du plan des bandelettes le long du bourrelet 21.The strips, forming the lateral edges of the shutter 9 and 10, are provided with a thickening 22 extending on either side of the plane of the strips along the bead 21.

Dans la figure 5, les moyens de transmission 5 et 6 sont constitués d'une bande métallique 19 qui forme un tout avec les pinces 20. Ces dernières sont découpées par poinçonnage suivi par emboutissage, d'une manière telle qu'alternativement une des lamelles s'étend d'un côté du plan de la bande métallique et du côté opposé de ce dernier. Ainsi, on obtient que les lamelles situées d'un côté du plan précité sont décalées par rapport à celles situées de l'autre côté de ce plan. Des saillies de guidage 29 et 30 sont formées d'une manière analogue.In the figure 5 , the transmission means 5 and 6 consist of a metal strip 19 which forms a whole with the clamps 20. The latter are cut by punching followed by stamping, in such a way that alternatively one of the strips extends from one side of the plane of the metal strip and the opposite side of the latter. Thus, we obtain that the slats located on one side of the aforementioned plane are offset from those located on the other side of this plane. Guide projections 29 and 30 are formed in a similar manner.

L'extrémité libre des lamelles orientée vers le volet 1, non représenté à la figure 5, est repliée vers l'extérieur quelque peu en forme d'entonnoir, de manière à faciliter l'introduction du bourrelet 21 dans les pinces formées par ces lamelles.The free end of the slats oriented towards the flap 1, not shown in FIG. figure 5 , is folded out somewhat somewhat in the form of a funnel, so as to facilitate the introduction of the bead 21 in the clamps formed by these strips.

Dans les figures 8 à 11, plusieurs formes de réalisation des bords latéraux 9 et 10 d'un volet 1 sont illustrées dans lesquelles ces bords latéraux 9 et 10 comprennent une bandelette 32 qui est attachée au volet 1.In the Figures 8 to 11 , several embodiments of the side edges 9 and 10 of a flap 1 are illustrated in which these side edges 9 and 10 comprise a strip 32 which is attached to the flap 1.

La figure 8 montre un volet 1 qui présente seulement un bourrelet 21 sans qu'un épaississement soit prévu.The figure 8 shows a flap 1 which has only a bead 21 without a thickening is expected.

Les bords latéraux 9 ou 10 du volet 1, représenté à la figure 9, sont pourvus d'un bourrelet 21 qui est espacé de l'épaississement 22.The side edges 9 or 10 of the shutter 1, shown in FIG. figure 9 , are provided with a bead 21 which is spaced from the thickening 22.

Les figures 10 et 11 montrent un volet 1 avec un bourrelet 21 et un épaississement 22 qui sont sensiblement analogues à ceux représentés à la figure 3.The Figures 10 and 11 show a flap 1 with a bead 21 and a thickening 22 which are substantially similar to those shown in FIG. figure 3 .

Dans la figure 10 la bandelette 32 est fixée des deux côtés du plan du volet 1, tandis que dans la figure 11, la bandelette 32 est fixée à un seul côté du volet 1.In the figure 10 the strip 32 is fixed on both sides of the plane of the flap 1, while in the figure 11 , the strip 32 is attached to one side of the flap 1.

Les figures 12 à 14 sont relatives à une roue dentée 35 qui fait partie des moyens d'entraînement. La roue dentée 35 est pourvu d'un trou cylindrique central 38 pour le montage sur l'axe 12 susmentionné et présente des dents 36 espacées l'une de l'autre tout autour de sa périphérie.The Figures 12 to 14 relate to a gear wheel 35 which is part of the drive means. The toothed wheel 35 is provided with a central cylindrical hole 38 for mounting on the aforementioned axis 12 and presents teeth 36 spaced apart from each other all around its periphery.

Afin d'assurer un bon engrènement avec les moyens de transmission 5 ou 6, la tangente 50 à la base des dents 36, située dans le plan de symétrie de la roue dentée 35, s'étend sensiblement radialement par rapport à cette dernière. De cette façon on évite que, par la force exercée par la roue 35 sur les moyens de transmission, et en particulier sur la bande métallique 19, cette dernière s'écarte radialement par rapport à la roue dentée 35. Comme il résulte clairement de la figure 14, les dents 36 présentent une section en forme d'une demi ellipse.To ensure a good meshing with the transmission means 5 or 6, the tangent 50 at the base of the teeth 36, located in the plane of symmetry of the toothed wheel 35, extends substantially radially relative to the latter. In this way it is avoided that, by the force exerted by the wheel 35 on the transmission means, and in particular on the metal strip 19, the latter moves radially away from the toothed wheel 35. As is clear from the figure 14 , the teeth 36 have a section in the form of a half ellipse.

Une autre forme de réalisation d'une roue dentée, suivant l'invention, est représentée aux figures 15 à 17. Dans cette forme de réalisation, la roue dentée 35 diffère de celle des figures précédentes par la forme des dents 36. Ces dernières présentent la forme d'une demi ellipsoïde.Another embodiment of a toothed wheel, according to the invention, is shown in FIGS. Figures 15 to 17 . In this embodiment, the toothed wheel 35 differs from that of the preceding figures by the shape of the teeth 36. The latter have the shape of a half ellipsoid.

Pour entraîner la roue 35 autour de son axe, un moyeu coaxial 39 en nylon avec celle-ci est monté contre une de ses faces latérales. Ce moyeu 39 est entraîné par l'axe 12, qui coopère avec le moteur électrique 13 susmentionné.To drive the wheel 35 about its axis, a nylon coaxial hub 39 with it is mounted against one of its side faces. This hub 39 is driven by the axis 12, which cooperates with the aforementioned electric motor 13.

La figure 18 montre un patin de guidage 40, à une position fixe, qui doit être placé au raz de la roue dentée 35 d'une manière telle à éviter que les moyens de transmission se dégagent par rapport à cette dernière. Ce patin de guidage 40 présente une forme qui correspond partiellement au contour de la roue dentée 35 et est pourvu d'un évidement 41, du côté dirigé vers cette dernière, qui s'étend selon pratiquement un quart du contour de la roue dentée 35, et ceci d'une manière telle à permettre aux dents 36 de se déplacer dans cet évidement 41 lorsque la roue dentée 35 tourne autour de son axe. La bande métallique 19 se déplace alors entre ce patin de guidage 40 et la roue dentée 35 de préférence sans qu'un contact existe entre cette dernière et la bande métallique 19. Ainsi, tout frottement entre le patin de guidage 40 et la bande métallique 19 est évité.The figure 18 shows a guide shoe 40, at a fixed position, which must be placed in the rudder of the toothed wheel 35 in such a way as to prevent the transmission means from being disengaged with respect thereto. This guide shoe 40 has a shape which corresponds partially to the contour of the toothed wheel 35 and is provided with a recess 41, on the side facing the latter, which extends along substantially a quarter of the contour of the toothed wheel 35, and this in such a way as to allow the teeth 36 to move in this recess 41 when the gear 35 is rotating about its axis. The metal strip 19 then moves between this guide pad 40 and the toothed wheel 35 preferably without any contact between the latter and the metal strip 19. Thus, any friction between the guide shoe 40 and the metal strip 19 is avoided.

Si un obstacle vient en contact avec le volet pendant l'ouverture ou la fermeture de ce dernier ou lorsque le volet 1 est complètement ou partiellement fermé ou ouvert, une force de traction transversale à la direction longitudinale des chemins de guidage 7 et 8 est exercée sur les bords latéraux 9 et 10 du volet 1 par rapport à la bande métallique 19. Si cette force est suffisamment importante, les bords latéraux 9 et 10 sont au moins partiellement séparés de cette bande métallique en dégageant le bourrelet 21 susmentionné des pinces 20.If an obstacle comes into contact with the shutter during the opening or closing thereof or when the shutter 1 is completely or partially closed or open, a traction force transverse to the longitudinal direction of the guide tracks 7 and 8 is exerted on the side edges 9 and 10 of the shutter 1 with respect to the metal strip 19. If this force is sufficiently large, the side edges 9 and 10 are at least partially separated from this metal strip by disengaging the aforementioned bead 21 from the clamps 20.

Par le fait que le volet 1 est séparé au moins partiellement des chemins de guidage 7 et 8, on évite que celui-ci soit endommagé ou qu'un accident grave se produise.In that the flap 1 is at least partially separated from the guideways 7 and 8, it is avoided that it is damaged or that a serious accident occurs.

Pour réintroduire les bords latéraux 9 et 10 et, par conséquent, pour rétablir la liaison entre les moyens de transmission 5 et 6 et le volet 1, des moyens de réintroduction 42 sont prévus près du côté supérieur de la baie 3 pour chacun des chemins de guidage 7 et 8.To reintroduce the lateral edges 9 and 10 and, consequently, to restore the connection between the transmission means 5 and 6 and the flap 1, reintroduction means 42 are provided near the upper side of the bay 3 for each of the paths of guidance 7 and 8.

Comme représenté à la figure 19, ces moyens de réintroduction 42 comprennent des organes qui permettent d'exercer une force de pression sur les bords latéraux 9 et 10 du volet 1 suivant une direction présentant une composante parallèle au plan du volet 1 et orientée vers les bords latéraux 9 et 10 de ce dernier.As represented in figure 19 these reintroduction means 42 comprise members which make it possible to exert a pressing force on the lateral edges 9 and 10 of the shutter 1 in a direction having a component parallel to the plane of the shutter 1 and oriented towards the lateral edges 9 and 10 of this last.

Lesdits organes sont formés par deux galets 43 et 44 qui sont disposés d'une manière à pouvoir exercer une telle force de pression sur une partie saillante des bords latéraux 9 et 10 formée par l'épaississement 22 susmentionné. Par suite de cette force de pression pendant l'ouverture ou la fermeture du volet 1, le bourrelet 21 des bords latéraux 9 et 10 est appliqué contre les extrémités libres repliées des pinces 20. D'une part, le bourrelet 21 est comprimé élastiquement, et, d'autre part, les pinces 20 sont déformées élastiquement afin que le bourrelet puisse rentrer entre les parties saillantes des pinces 20 sous l'action des galets 43 et 44, de sorte que les bords latéraux 9 et 10 soient à nouveau liés aux moyens de transmission 5 et 6.Said members are formed by two rollers 43 and 44 which are arranged in such a way as to be able to exert such a pressing force on a projecting part of the lateral edges 9 and 10 formed by the thickening 22 mentioned above. As a result of this pressing force during the opening or closing of the shutter 1, the bead 21 of the lateral edges 9 and 10 is applied against the folded free ends of the clamps 20. On the one hand, the bead 21 is elastically compressed, and, on the other hand, the clamps 20 are elastically deformed so that the bead can fit between the projecting parts of the clamps 20 under the action of the rollers 43 and 44, so that the side edges 9 and 10 are again connected to the transmission means 5 and 6.

Les galets 43 et 44 représentés à la figure 19 sont disposés obliquement et symétriquement de part et d'autre du plan du volet 1. Ceci évite que les bords latéraux 9 et 10 puissent être bloqués, par exemple, entre les chemins de guidage 7 et 8 et les galets 43 et 44. De préférence, une distance de l'ordre de 1 mm est maintenu entre le volet 1 et les galets 43 et 44 afin d'éviter tout frottement entre le volet 1 et ces galets 43 et 44 lorsque ce dernier est guidé par les chemins de guidage 7 et 8 pendant le déplacement entre sa position d'ouverture et de fermeture.The rollers 43 and 44 shown in figure 19 are arranged obliquely and symmetrically on either side of the plane of the shutter 1. This prevents the side edges 9 and 10 can be blocked, for example, between the guideways 7 and 8 and the rollers 43 and 44. Preferably a distance of the order of 1 mm is maintained between the flap 1 and the rollers 43 and 44 to prevent any friction between the flap 1 and these rollers 43 and 44 when the latter is guided by the guideways 7 and 8 during movement between its open and closed position.

Dans certains cas, en particulier, lorsque les bords latéraux 9 et 10 du volet 1 sont peu flexible, il n'est généralement pas nécessaire de prévoir des moyens de réintroduction. Lors de l'ouverture du volet 1, le bourrelet 21 est automatiquement réintroduit dans les pinces 20 par suite de la rigidité des bords latéraux 9 et 10 du volet 1.In some cases, in particular, when the side edges 9 and 10 of the flap 1 are not very flexible, it is generally not necessary to provide reintroduction means. When opening the shutter 1, the bead 21 is automatically reintroduced into the clamps 20 as a result of the rigidity of the side edges 9 and 10 of the shutter 1.

Les chemins de guidage 7 et 8 sont conçus d'une manière telle à former une glissière pour les moyens de transmission 5 et 6. Dans la forme de réalisation représentée en coupe transversale à la figure 20 d'un chemin de guidage 7 ou 8, ce dernier comprend quatre profilés 45 sensiblement continus en forme de L qui sont montés symétriquement par rapport à la bande métallique 19 des moyens de transmission 5 ou 6.The guideways 7 and 8 are designed in such a way as to form a slideway for the transmission means 5 and 6. In the embodiment shown in cross-section at the figure 20 of a guide path 7 or 8, the latter comprises four substantially continuous L-shaped sections 45 which are mounted symmetrically with respect to the metal strip 19 of the transmission means 5 or 6.

Les profilés 45 sont disposés d'une telle manière à former un espace libre en forme de croix dans lequel peut se déplacer la bande métallique 19 pourvue des saillies de guidages 29 et 30. Afin d'obtenir une distance constante entre les profilés 45 pour le passage de saillies de guidage 29 et 30. un plat support 46, qui s'entend transversalement au plan du volet 1, est monté entre les profilés 45.The profiles 45 are arranged in such a way as to form a free cross-shaped space in which the metal strip 19 provided with the guide projections 29 and 30 can be moved. In order to obtain a constant distance between the profiles 45 for the passing guide projections 29 and 30. a support plate 46, which extends transversely to the plane of the shutter 1, is mounted between the profiles 45.

Pour maintenir une distance constante entre les profilés 45, requise pour le glissement de la bande métallique 19 entre ces profilés 45, un profilé 47 de section en forme de U est fixé, au moyens de boulons 51, aux plats supports 46. La partie de la bande métallique 19 présentant les évidements 31 coopérant avec les moyens d'entraînement se situe dans la cavité formée par le profilé 47.To maintain a constant distance between the profiles 45, required for the sliding of the metal strip 19 between these sections 45, a U-section section section 47 is fixed, by means of bolts 51, to the support plates 46. the metal band 19 having the recesses 31 cooperating with the drive means is in the cavity formed by the profile 47.

Les profilés 45 sont avantageusement réalisés en une matière électriquement isolante, comme par exemple du nylon.The profiles 45 are advantageously made of an electrically insulating material, such as nylon.

Dans la figure 21, le chemin de guidage 7 ou 8 de la figure 20 est montré à la hauteur de la roue dentée 35 susmentionnée. Comme le montre clairement cette figure, la bande métallique 19 est située entre la roue dentée 35 et le patin anti-bourrage 40, tandis que les dents 36 s'étendent à travers les évidements 31 de la bande métallique 19 dans l'évidement 41 du patin anti-bourrage 40. A cette hauteur, le profilé 47 est interrompu.In the figure 21 , the guide path 7 or 8 of the figure 20 is shown at the height of the aforementioned gear wheel 35. As clearly shown in this figure, the metal strip 19 is located between the toothed wheel 35 and the anti-jam pad 40, while the teeth 36 extend through the recesses 31 of the metal strip 19 in the recess 41 of the anti-jam pad 40. At this height, the section 47 is interrupted.

Quand un obstacle se trouve en-dessous du volet 1 et fait contact avec le bord libre 16 du volet 1 lors de la fermeture de ce dernier ou lors d'un accrochage accidentelle du volet 1, les bords latéraux 9 et 10 près du bord libre 16 sont séparés des moyens de transmission 5 et 6 et la liaison entre les moyens de transmission 5 et 6 et le revêtement 49 est interrompue.When an obstacle is below the shutter 1 and makes contact with the free edge 16 of the shutter 1 during the closure of the latter or during an accidental snap of the shutter 1, the side edges 9 and 10 near the free edge 16 are separated from the transmission means 5 and 6 and the connection between the transmission means 5 and 6 and the coating 49 is interrupted.

De cette façon, un circuit électrique est formé, comme représenté schématiquement dans la figure 24, qui est connecté à un dispositif de commande 64 d'une manière telle que lors de l'interruption du circuit électrique, le déplacement du volet 1 est immédiatement arrêté.In this way, an electric circuit is formed, as shown schematically in the figure 24 which is connected to a control device 64 in such a way that when the electrical circuit is interrupted, the movement of the shutter 1 is immediately stopped.

Lorsqu'un obstacle se trouve en dessous du volet pendant la fermeture de celui, telle qu'une personne, le volet 1 s'arrête immédiatement après que le bord libre 16 de ce dernier entre en contact avec cet obstacle et est amené automatiquement dans sa position d'ouverture.When an obstacle is beneath the shutter during the closing of the shutter, such as a person, the shutter 1 stops immediately after the free edge 16 of the latter comes into contact with this obstacle and is automatically brought into its shutter. opening position.

Afin de déterminer s'il y a un tel obstacle dans la baie 3, des moyens de détection sont prévus, comme représentés aux figures 22 et 23. Ces moyens de détection comprennent, d'une part, un conducteur électrique 48 incorporé dans le bord inférieur 16 du volet 1 et s'étendant sur toute la largueur de ce dernier de manière à former un contact avec les moyens de transmission 5 et 6, et, d'autre part, un matériau conducteur d'électricité faisant parti des moyens de transmission et formant avec le conducteur électrique 48 le circuit électrique précité.In order to determine if there is such an obstacle in the bay 3, detection means are provided, as shown in FIGS. Figures 22 and 23 . These detection means comprise, on the one hand, an electrical conductor 48 incorporated in the lower edge 16 of the shutter 1 and extending over the entire width of the latter so as to form a contact with the transmission means 5 and 6, and, on the other hand, an electrically conductive material forming part of the transmission means and forming with the electrical conductor 48 the aforementioned electrical circuit.

Ce circuit électrique est, par conséquent, constitué par les bandes métalliques 19, le conducteur électrique 48 et deux fils électriques 65 et 66 qui connectent le dispositif de commande 64 avec chacun des bandes métalliques 19 par contact de balais conducteurs 67 et 68. Les bandes métalliques 19 sont isolés électriquement par rapport aux chemins de guidages 7 et 8 vu qu'elles sont guidées par des profilés 45 qui ne sont pas conducteur d'électricité. Les roues dentées 35 sont également formées d'une matière non conductrice d'électricité, comme du nylon. Les roues dentées 35 sont éventuellement constituées d'une bande métallique en forme de cylindre qui enserre un noyau cylindrique en nylon afin d'éviter l'usure de la roue dentée 35 et de garantir que la bande métallique 19, et ainsi ce circuit électrique, est isolée électriquement par rapport aux autres éléments du dispositif de fermeture.This electrical circuit is, consequently, constituted by the metal strips 19, the electrical conductor 48 and two electrical wires 65 and 66 which connect the control device 64 with each of the metal strips 19 by contact with conducting brushes 67 and 68. metal 19 are electrically insulated from the guideways 7 and 8 as they are guided by sections 45 which are not electrically conductive. The gears 35 are also formed of a non-electrically conductive material, such as nylon. The toothed wheels 35 may consist of a metal strip in the form of a cylinder which encloses a cylindrical nylon core in order to avoid wear of the toothed wheel 35 and to guarantee that the metal strip 19, and thus this electric circuit, is electrically insulated from the other elements of the closure device.

Dans la forme de réalisation montrée aux figures 22 et 23, le matériau conducteur est formé d'un revêtement métallique 49 recouvrant le bord latéral saillant du volet 1 à proximité du bord inférieur 16 de ce dernier et formant un contact électrique avec les moyens de transmission, notamment avec la bande métallique 19.In the embodiment shown to Figures 22 and 23 , the conductive material is formed of a metal coating 49 covering the lateral edge projecting from the shutter 1 near the lower edge 16 of the latter and forming an electrical contact with the transmission means, in particular with the metal strip 19.

Ainsi, le circuit électrique est interrompu lorsque le bord latéral 9 ou 10 est séparé des moyens de transmission 5 ou 6 et un signal est donné au dispositif de commande 64 qui, automatiquement, provoque l'arrêt et l'ouverture du volet 1 en agissant sur l'alimentation ou la commande du moteur 13 des moyens d'entraînement du volet 1.Thus, the electric circuit is interrupted when the side edge 9 or 10 is separated from the transmission means 5 or 6 and a signal is given to the control device 64 which automatically causes the shutter 1 to stop and open by acting on the power supply or the motor control 13 of the drive means of the shutter 1.

Le lien des moyens d'accrochage, c.à.d. des pinces 20, avec les bords latéraux 9 et 10 est de préférence plus faible près du bord inférieur 16 de ce dernier qu'aux autres endroits.The link of the attachment means, i.e. clamps 20, with the side edges 9 and 10 is preferably lower near the lower edge 16 of the latter at other locations.

Les figures 25 à 30 montrent schématiquement différentes formes de réalisation non limitatives de la façon suivant laquelle a lieu le déplacement du volet 1 à partir de sa position de fermeture vers sa position d'ouverture.The Figures 25 to 30 schematically show various non-limiting embodiments of the manner in which takes place the movement of the flap 1 from its closed position to its open position.

La figure 25 est relative à la forme de réalisation telle que représentée à la figure 1, dans laquelle le volet 1, dans sa position d'ouverture, s'étend sensiblement horizontalement à un niveau situé au-dessus de la baie 3.The figure 25 relates to the embodiment as shown in FIG. figure 1 , in which the flap 1, in its open position, extends substantially horizontally at a level above the bay 3.

La figure 26 est relative à une forme de réalisation qui diffère par rapport à celle de la figure 25 par le fait que le volet 1, pour l'amener dans sa position d'ouverture, subit un retour de 180° vers le bas à partir de la position horizontale montrée à la figure 25. Dans une variante de cette forme de réalisation, ce retour de 180° peut avoir lieu vers le haut.The figure 26 relates to an embodiment which differs from that of the figure 25 in that the flap 1, to bring it into its open position, undergoes a return of 180 ° downwards from the horizontal position shown in FIG. figure 25 . In a variant of this embodiment, this return of 180 ° can take place upwards.

Dans la figure 27, le volet est, dans sa position d'ouverture, enroulé en spirale autour d'un axe horizontal parallèle à celui des roues dentées des moyens d'entraînement. Dans une variante, l'axe d'enroulement peut coïncider avec l'axe des roues dentées précitées. Dans ce cas, les moyens d'entraînement comprennent un bras télescopique coopérant avec l'extrémité supérieur des bords latéraux du volet 1, comme, par exemple, décrit dans la demande de brevet WO 95/30064 (pages 11 et 12).In the figure 27 , the flap is, in its open position, wound in a spiral about a horizontal axis parallel to that of the toothed wheels of the drive means. In a variant, the winding axis may coincide with the axis of the aforementioned gears. In this case, the drive means comprise a telescopic arm cooperating with the upper end of the side edges of the flap 1, as for example described in the application of WO 95/30064 (pages 11 and 12).

Dans la figure 28, le volet 1 subit, pour passer de sa position de fermeture vers sa position d'ouverture, après sa coopération avec les roues dentées, une déviation vers le haut suivie d'un déplacement à l'horizontale.In the figure 28 , the flap 1 undergoes, to move from its closed position to its open position, after its cooperation with the gear wheels, an upward deflection followed by a horizontal displacement.

Dans la forme de réalisation suivant la figure 29, le volet 1 est, dans sa position d'ouverture, plié en zig-zag après sa coopération avec les roues dentées.In the embodiment according to figure 29 , the flap 1 is, in its open position, folded zig-zag after its cooperation with the gears.

Enfin, dans la figure 30, le volet 1 subit un déplacement vertical dans son plan pour passer de la position de fermeture vers sa position d'ouverture.Finally, in the figure 30 , the shutter 1 is vertically displaced in its plane to move from the closed position to its open position.

Le choix d'une de ces solutions dépend, d'une part, des possibilités offertes par l'espace au-dessus de la baie 3 et, d'autre part, par la nature même du volet 1.The choice of one of these solutions depends, on the one hand, on the possibilities offered by the space above bay 3 and, on the other hand, by the very nature of flap 1.

Dans certains cas, par exemple pour des portes d'une grande largeur, le volet 1 et la bande 19 peuvent se replier librement en zig-zag dans un bac prévu au dessus de la baie 3 pendant l'ouverture de cette dernière.In some cases, for example for doors of great width, the flap 1 and the strip 19 can fold freely zig-zag in a tray provided above the bay 3 during the opening of the latter.

Les figures 31 à 34 montrent des moyens de transmission 5 et 6 qui sont particulièrement intéressante pour un volet 1 qui présente une grande surface. Ces moyens de transmission 5 et 6 comprennent une chaîne 52 qui est constituée d'une succession de tiges 53 parallèles espacées, qui sont reliées entre elles par des plaquettes articulées 54, sur les extrémités de ce tiges 53. Il s'agit en particulier d'un chaîne 52 ayant l'allure d'une chaîne de bicyclette.The Figures 31 to 34 show transmission means 5 and 6 which are particularly interesting for a flap 1 which has a large surface. These transmission means 5 and 6 comprise a chain 52 which consists of a succession of spaced parallel rods 53, which are interconnected by articulated plates 54, on the ends of these rods 53. a chain 52 having the shape of a bicycle chain.

Les chemins de guidage 7 et 8 comprennent un profilé 55 qui présente en section transversale deux bras 56 et 57 en forme de L s'étendant tout le long des chemins de guidage 7 et 8, d'une manière telle qu'une fente est ménagée entre les extrémités des bras 56 et 57 dans laquelle pénètrent les tiges 53 avec leur axe sensiblement transversalement à la direction de déplacement du volet 1.The guideways 7 and 8 comprise a profile 55 which has in cross section two L-shaped arms 56 and 57 extending along the guide tracks 7 and 8, in such a way that a slot is provided. between the ends of the arms 56 and 57 in which the rods 53 penetrate with their axis substantially transversely to the direction of movement of the flap 1.

Un rebord est formé par les bras 56 et 57 contre lesquelles appuient les plaquettes 54 d'un côté des tiges 53 afin d'éviter que la chaîne ne se dégage du profilé 55.A flange is formed by the arms 56 and 57 against which the plates 54 support one side of the rods 53 to prevent the chain from emerging from the profile 55.

Les plaquettes 54 du côté du volet 1 présentent un rebord qui s'étend dans un plan parallèle au volet 1 permettant de fixer la chaîne 52 au moyen de boulons 58 au volet 1.The plates 54 on the side of the flap 1 have a rim which extends in a plane parallel to the flap 1 making it possible to fix the chain 52 by means of bolts 58 to the flap 1.

Ces boulons 58 sont de préférence réalisés en un matériau à coefficient de cisaillement relativement faible, comme du nylon, de sorte que, lorsqu'une force est appliquée au volet 1 par suite d'un obstacle qui entre en contact avec le volet 1 dans la direction de la flèche 59, les boulons 58 cassent et le volet 1 est séparé au moins partiellement de la chaîne 52, comme représenté à la figure 33.These bolts 58 are preferably made of a relatively low shear coefficient material, such as nylon, so that when a force is applied to the flap 1 as a result of an obstacle which comes into contact with the flap 1 in the direction of the arrow 59, the bolts 58 break and the flap 1 is at least partially separated from the chain 52, as shown in FIG. figure 33 .

Les figures 35 et 36 représentent des moyens d'accrochage qui comprennent une pince 20 continue qui s'étend sur toute la longueur des bords latéraux 9 et 10 du volet 1. Le bourrelet 21 présente une section en forme de triangle de sorte qu'il peut être enserré aisément dans la pince continue 20.The Figures 35 and 36 represent hooking means which comprise a continuous gripper which extends over the entire length of the side edges 9 and 10 of the flap 1. The bead 21 has a triangular section so that it can be easily gripped in the clamp continues 20.

Lorsque une force de traction est exercée sur les bords latéraux du volet 9 et 10, les lamelles 25 et 26, constituant la pince 20, s'écartent, comme indiqué par les flèches 60 et 61, et le volet 1 est séparé de la pince 20.When a pulling force is exerted on the side edges of the shutter 9 and 10, the slats 25 and 26 constituting the clamp 20, deviate, as indicated by the arrows 60 and 61, and the shutter 1 is separated from the clamp 20.

Il est bien entendu que dans cette forme de réalisation de l'invention, les pince 20 sont de préférence flexibles dans la direction transversale au plan du volet 1 pour que les moyens de transmission puissent être guidés dans des chemins de guidage 7 et 8 qui ne sont pas rectilignes pour permettre le passage dans des courbes et l'enroulement.It is understood that in this embodiment of the invention, the clamps 20 are preferably flexible in the direction transverse to the plane of the flap 1 so that the transmission means can be guided in guideways 7 and 8 which do not are not rectilinear to allow the passage in curves and the winding.

Dans la forme de réalisation de l'invention représentée à la figure 37, les moyens d'accrochage sont formés par deux rubans tissés différemment 62 et 63 qui s'agrippent par contact. Ces rubans 62 et 63 sont commercialisés sous le nom "Velcro". A savoir un ruban masculin et un ruban femelle. Un de ces rubans est attaché au bord latéral du volet 1, l'autre étant rendu solidaire de la bande métallique 19.In the embodiment of the invention shown in figure 37 , the attachment means are formed by two differently woven ribbons 62 and 63 which grip by contact. These ribbons 62 and 63 are marketed under the name "Velcro". Namely a male ribbon and a female ribbon. One of these ribbons is attached to the side edge of the flap 1, the other being secured to the metal strip 19.

De cette façon une liaison amovible est obtenue entre les moyens de transmission 5 et 6 et le volet 1.In this way a removable connection is obtained between the transmission means 5 and 6 and the shutter 1.

Des moyens de réintroduction peuvent être prévus qui sont adaptés aux moyens d'accrochage utilisés. Lorsque ces moyens d'accrochage comprennent des rubans 62 et 63 qui s'agrippent par contact, les moyens de réintroduction sont par exemple constitués par deux galets qui sont disposés de part et d'autre de la bande 19 de sorte que, pendant l'ouverture ou la fermeture du volet 1, ces galets poussent les rubans 62 et 63 l'un contre l'autre afin de rétablir le lien entre le volet 1 et la bande métallique 19.Reintroduction means may be provided which are adapted to the attachment means used. When these attachment means comprise tapes 62 and 63 which grip by contact, the reintroduction means are for example constituted by two rollers which are arranged on either side of the band 19 so that during the opening or closing the shutter 1, these rollers push the ribbons 62 and 63 against each other to restore the link between the shutter 1 and the metal strip 19.

Les figures 38 à 42 montrent les étapes successives de la déformation d'un bourrelet 21 compressible avec une section triangulaire, lors de la séparation du volet 1 des pinces 20.The Figures 38 to 42 show the successive stages of the deformation of a compressible bead 21 with a triangular section, during the separation of the flap 1 of the clamps 20.

Les figures 43 à 47 montrent les étapes successives de la déformation d'un bord latérale 9 et 10 en forme de T lors de la séparation du volet 1 des moyens de transmission. En retirant le bord latéral des pinces 20 les deux bras du T sont repliés l'un contre l'autre en permettant ainsi de le dégager facilement.The Figures 43 to 47 show the successive steps of the deformation of a T-shaped side edge 9 and 10 during the separation of the flap 1 of the transmission means. By removing the side edge of the clamps 20 the two arms of the T are folded against each other thus allowing it to be easily disengaged.

Les figures 48 à 50 montrent des étapes successives de la déformation des pinces 20 lors de la séparation du volet 1 des moyens de transmission dans le cas où ces derniers sont sensiblement élastiques et le bourrelet 21 est sensiblement incompressible.The Figures 48 to 50 show successive stages of the deformation of the clamps 20 during the separation of the flap 1 of the transmission means in the case where the latter are substantially elastic and the bead 21 is substantially incompressible.

Dans le cas représenté aux figures 51 à 54, les pinces 20 et le bourrelet 21 sont réalisé en une matière élastique de manière à pouvoir se déformer élastiquement lors de la séparation du volet 1 des moyens de transmission.In the case shown in Figures 51 to 54 , the clamps 20 and the bead 21 are made of a resilient material so as to be elastically deformable during the separation of the flap 1 of the transmission means.

Afin d'assurer que le volet 1 soit bien tendu entre les chemins de guidage 7 et 8 et qu'il puisse reprendre des tolérances de fabrication et de montage, sans qu'il soit séparé des moyens de transmission, il est de préférence fixé d'une manière élastique aux moyens de transmission.In order to ensure that the shutter 1 is well tensioned between the guideways 7 and 8 and that it can take up manufacturing and assembly tolerances, without it being separated from the transmission means, it is preferably attached to an elastic manner to the transmission means.

Dans la figure 55 le bourrelet 21 est prévu aux bords latéraux 9 et 10 du volet 1 et présent de part et d'autre de ce dernier une face 69 et 70 qui est inclinée par rapport au plan du volet 1 d'une manière telle à former un coin. Les pinces 20 s'appuient contres ces faces 69 et 70. Lorsque les bords latéraux 9 ou 10 du volet 1 sont déplacés d'une certaine distance par suite d'une force qui est exercée sur ce dernier, les pinces 20 glissent sur les faces 69 et 70 du bourrelet 1 sans que le volet 1 est séparé des pinces 20 si cette force n'est pas suffisamment grande pour la provoquer la séparation des pinces 20 du volet 1. Une telle situation est représentée par une pince 20 en traits. Quand cette force n'agit plus sur le volet 1, les pinces 20 sont guidées par les faces 69 et 70 vers le volet 1 et tendent celui-ci.In the figure 55 the bead 21 is provided at the side edges 9 and 10 of the flap 1 and present on either side of the latter a face 69 and 70 which is inclined relative to the plane of the flap 1 in such a way as to form a wedge. The clamps 20 rest against these faces 69 and 70. When the side edges 9 or 10 of the shutter 1 are moved a certain distance due to a force which is exerted on the latter, the clamps 20 slide on the faces 69 and 70 of the bead 1 without the flap 1 is separated from the clamps 20 if this force is not large enough to cause the separation of the clamps 20 of the flap 1. Such a situation is represented by a pincer 20 in phantom. When this force no longer acts on the flap 1, the clamps 20 are guided by the faces 69 and 70 to the flap 1 and tend it.

Une variante du bourrelet de la figure 55 est représentée à la figure 56. Dans cette figure, le bourrelet 21 présente également deux faces 69 et 70 inclinées par rapport au plan du volet 1. Ces faces 69 et 70 sont revêtues d'une matière élastiquement compressible 71, de sorte que le volet 1 reste toujours tendu lorsque celui-ci est lié aux pinces 20 à cause de la déformation élastique de cette matière 20, qui est par exemple formée par du caoutchouc.A variant of the bead of the figure 55 is represented at the figure 56 . In this figure, the bead 21 also has two faces 69 and 70 inclined relative to the plane of the flap 1. These faces 69 and 70 are coated with an elastically compressible material 71, so that the flap 1 is still stretched when it is connected to the clamps 20 because of the elastic deformation of this material 20, which is for example formed by rubber.

Dans la figure 57, une partie des pinces 20 se présente sous forme d'un ressort 72 pouvant être déformé élastiquement dans la direction de la flèche 73, de manière à pouvoir tendre le volet 1.In the figure 57 a part of the clamps 20 is in the form of a spring 72 which can be elastically deformed in the direction of the arrow 73 so as to be able to tension the shutter 1.

Les moyens d'accrochage ne sont pas nécessairement constitués de pinces. Ainsi dans la figure 58 le volet 1 présente aux bords latéraux 9 et 10 une succession de petits blocs séparés 74, de préférence reliés d'une manière flexible entre eux. Ces blocs 74 sont, par exemple, formés par des "mailles" d'une fermeture à glissière traditionnelle.The attachment means are not necessarily made of clamps. So in the figure 58 the flap 1 has at the side edges 9 and 10 a succession of small separate blocks 74, preferably connected in a flexible manner between them. These blocks 74 are, for example, formed by "meshes" of a traditional zipper.

Chacun des chemins de guidages 7 et 8, comme représenté à la figure 59, comprend deux profilés longitudinaux 77 et 78 présentant une section transversale de forme rectangulaire. Ces profilés sont pourvus de rebords 75 et 76 s'étendant de part et d'autre des bords latéraux 9 et 10 du volet 1. Ces rebords 75 et 76 sont dirigés l'un vers l'autre, de manière à entourer partiellement les petits blocs 74.Each of the guideways 7 and 8, as shown in FIG. figure 59 comprises two longitudinal sections 77 and 78 having a rectangular cross-section. These profiles are provided with flanges 75 and 76 extending on either side of the side edges 9 and 10 of the shutter 1. These flanges 75 and 76 are directed towards each other, so as to partially surround the small blocks 74.

Une bande métallique 19 est prévue, pouvant coopérer avec des moyens d'entraînement, qui présente des moyens d'accrochage sous forme d'un bord dentelé 79. Comme représenté à la figure 58, ce bord dentelé s'engrène avec la succession des petits blocs 74 fixés aux bords latéraux 9 et 10 du volet 1.A metal strip 19 is provided, which can cooperate with drive means, which has hooking means in the form of a serrated edge 79. As shown in FIG. figure 58 this serrated edge meshes with the succession of small blocks 74 fixed to the side edges 9 and 10 of the shutter 1.

La bande métallique 19 est guidée dans un évidement correspondant ménagé entre les profilés 77 et 78 et est entraînée par une roue dentée 35, non représentée dans les figures 58 et 59.The metal strip 19 is guided in a corresponding recess formed between the sections 77 and 78 and is driven by a toothed wheel 35, not shown in FIGS. Figures 58 and 59 .

Lorsqu'une certaine force de traction, transversale aux chemins de guidage 7 et 8, est exercée sur les bords latéraux 9 et 10 du volet 1, ce dernier est séparé de la bande métallique 19 en dégageant les blocs 74 des chemins de guidage 7 et 8, par la déformation élastique des rebords 75 et 76.When a certain traction force, transverse to the guideways 7 and 8, is exerted on the side edges 9 and 10 of the shutter 1, the latter is separated from the metal strip 19 by disengaging the blocks 74 from the guideways 7 and 8, by the elastic deformation of the flanges 75 and 76.

Un système de réintroduction, qui est similaire à celui décrit dans le brevet EP 0 272 733 , peut être prévu pour réintroduire les blocs 74 dans les chemins de guidage 7 et 8.A reintroduction system, which is similar to that described in EP 0 272 733 , may be provided to reintroduce the blocks 74 in the guideways 7 and 8.

La figure 60 représente un dispositif de fermeture dans lequel une seule roue dentée 35 est prévue à un des deux chemins de guidage 7 ou 8. Pour la clarté de la figure, ces chemins de guidage ne sont pas représentés.The figure 60 represents a closure device in which a single gear 35 is provided at one of the two guideways 7 or 8. For clarity of the figure, these guideways are not shown.

Dans cette forme de réalisation, suivant l'invention, le volet 1 est pourvu d'une plaque rigide 80 qui s'étend sur toute la largeur du volet 1 et qui est liée d'une manière fixe aux bandes métalliques 19 de chacun des bords latéraux 9 et 10 du volet 1.In this embodiment, according to the invention, the shutter 1 is provided with a rigid plate 80 which extends over the entire width of the shutter 1 and which is fixedly connected to the metal strips 19 of each of the edges. 9 and 10 of the flap 1.

Lors de la fermeture d'une baie 3 par le volet 1, la plaque rigide 80 reste au-dessus du patin de guidage 40 et de la roue dentée 35.When closing a bay 3 by the flap 1, the rigid plate 80 remains above the guide shoe 40 and the toothed wheel 35.

La figure 61 représente un système de verrouillage comprenant deux barres 81 et 82 qui s'étendent parallèlement aux chemins de guidage 7 et 8 et qui peuvent être déplacées suivant la direction des flèches 83 entre une position non-verrouillée, représentée par des traits interrompus, et une position verrouillée montrée en traits pleins. Dans la position verrouillé, les barres 81 et 82 s'étendent le long des bords latéraux 9 et 10 du volet 1, de sorte que les pinces 20 sont coincées entre ces barres 81 et 82 en évitant que le bourrelet 21 du volet 1 puisse se séparer des pinces 20.The figure 61 represents a locking system comprising two bars 81 and 82 which extend parallel to the guideways 7 and 8 and which can be moved in the direction of the arrows 83 between an unlocked position, represented by dashed lines, and a position locked shown in solid lines. In the locked position, the bars 81 and 82 extend along the side edges 9 and 10 of the shutter 1, so that the clamps 20 are wedged between these bars 81 and 82 while preventing the bead 21 of the shutter 1 from separate clamps 20.

Dans la figure 62 une variante du système de verrouillage est représentée dans laquelle les barres 81 et 82 peuvent pivoter autour d'un axe 84 et 85 entre une position non-verrouillée et un position verrouillée.In the figure 62 a variant of the locking system is shown in which the bars 81 and 82 are pivotable about an axis 84 and 85 between an unlocked position and a locked position.

Les barres 81 et 82 peuvent être verrouillées manuellement ou automatiquement lorsque la baie 3 est fermée par le volet 1.The bars 81 and 82 can be locked manually or automatically when the bay 3 is closed by the shutter 1.

Dans les figures 63 à 66 une forme de réalisation particulièrement intéressante de l'invention est représentée. Dans cette forme de réalisation les moyens de transmission sont constitués d'une bande souple 86, comme par exemple une sangle textile, pourvue d'une succession de pinces 20 qui peuvent être fixées aux bords latéraux d'un volet 1, non représenté dans les figures.In the Figures 63 to 66 a particularly interesting embodiment of the invention is shown. In this embodiment the transmission means consist of a flexible band 86, such as for example a textile strap, provided with a succession of clamps 20 which can be attached to the side edges of a flap 1, not shown in FIGS. FIGS.

La bande 86 est entraînée, par l'intermédiaire des pinces 20, par une roue dentée 35 qui est constituée de deux poulies 87 et 88 parallèles montées, à une certaine distance l'une de l'autre, sur un axe de rotation commun 12 et pourvues de dents 36.The strip 86 is driven, via the clamps 20, by a toothed wheel 35 which consists of two parallel pulleys 87 and 88 mounted, at a distance from each other, on a common axis of rotation 12 and provided with teeth 36.

Les pinces 20 présentent deux plaquettes rigides 90 et 91 appliquées de part et d'autre contre la bande souple 86 au moyen de rivets 89. Les plaquettes 90 qui sont orientées vers la roue dentée 35 sont espacées l'une de l'autre d'une distance qui est suffisante pour permettre de courber la bande 86 contre au moins une partie de la périphérie de cette roue dentée 35.The clamps 20 have two rigid plates 90 and 91 applied on either side against the flexible band 86 by means of rivets 89. The plates 90 which are oriented towards the toothed wheel 35 are spaced apart from one another. a distance which is sufficient to allow the strip 86 to be bent against at least a part of the periphery of this toothed wheel 35.

Les plaquettes rigides 91, qui sont orientées vers le côté opposé à la roue dentée 35, s'appuient librement l'une contre l'autre lorsque la bande souple 86 est guidée dans des chemins de guidage droit. Ainsi il est possible d'exercer une force de poussée sur la bande souple 86 suivant la direction de la flèche 92 par la rotation de la roue dentée 35 afin de fermer une baie par le volet 1 qui est fixé aux pinces 20.The rigid pads 91, which are oriented towards the opposite side of the toothed wheel 35, abut freely against each other when the flexible band 86 is guided in straight guideways. Thus it is possible to exert a thrust force on the flexible strip 86 in the direction of the arrow 92 by the rotation of the toothed wheel 35 to close a bay by the flap 1 which is fixed to the clamps 20.

Les bords 94 et 95 des plaquettes 91 s'étendent entre les poulies 87 et 88 et sont repliés transversalement par rapport au plan de ces plaquettes. Les côtés latéraux des bords ainsi formés s'appuient alors l'un contre l'autre pendant la fermeture du volet 1.The edges 94 and 95 of the plates 91 extend between the pulleys 87 and 88 and are folded transversely relative to the plane of these plates. The lateral sides of the edges thus formed then bear against each other during the closure of the shutter 1.

Les plaquettes rigides 91, orientées vers le côté opposé à la roue dentée 35, présentent une largeur qui est plus grand que la distance entre les poulies 87 et 88 de la roue dentée 35, tandis que les plaquettes rigides 90 et la bande souple 86 ont une largeur qui est plus petite que cette distance. Pour permettre la coopération des dents 36 avec les plaquettes rigides 91, celles-ci présentent à chaque coin un évidement 93 dans lequel les dents 36 peuvent s'engrener.The rigid pads 91, facing the opposite side of the gear 35, have a width which is greater than the distance between the pulleys 87 and 88 of the gear wheel 35, while the rigid pads 90 and the flexible band 86 have a width that is smaller than this distance. To allow cooperation teeth 36 with the rigid plates 91, these have at each corner a recess 93 in which the teeth 36 can mesh.

Il est claire qu'il n'est pas indispensable que les plaquettes 90, dirigées vers la roue dentée 35, sont rigides. Dans une variante de cette forme de réalisation de l'invention, les pinces 20 peuvent être constituées d'une seule plaquette rigide 91 qui est fixées au côté de la bande souple 86 qui est éloignée de la roue dentée 35.It is clear that it is not essential that the plates 90, directed towards the toothed wheel 35, are rigid. In a variant of this embodiment of the invention, the clamps 20 may consist of a single rigid plate 91 which is fixed to the side of the flexible band 86 which is remote from the gear wheel 35.

Il est bien entendu que l'invention n'est pas limitée aux différentes formes de réalisation décrites ci-dessus, mais que d'autres variantes encore peuvent être envisagées sans sortir du cadre de la présente invention, notamment en ce qui concerne les moyens de transmission et d'entraînement, ainsi que de la constitution du volet et du système de réintroduction.It is understood that the invention is not limited to the various embodiments described above, but that other variants may be envisaged without departing from the scope of the present invention, especially with regard to the means of transmission and training, as well as the constitution of the component and the reintroduction system.

Ainsi, dans certains cas, lorsque le volet est constitué d'une matière souple, des barres de raidissement et/ou de lestage pourraient être incorporées dans le volet.Thus, in some cases, when the flap is made of a flexible material, stiffening bars and / or ballast could be incorporated in the flap.

Par ailleurs, les chemins de guidage 7 et 8 ne doivent pas être entièrement droits et peuvent être courbés.Moreover, the guideways 7 and 8 must not be completely straight and may be curved.

De plus, le dispositif de fermeture suivant l'invention n'est pas limité à des portes avec des chemins de guidage verticaux, mais peut également présenter des chemins de guidage horizontaux. Dans certains cas, il est possible de prévoir seulement un chemin de guidage horizontal au côté supérieur d'une baie, de sorte que le volet est suspendu à ce chemin de guidage.In addition, the closure device according to the invention is not limited to doors with vertical guideways, but may also have horizontal guideways. In some cases, it is possible to provide only a horizontal guide path to the upper side of a bay, so that the flap is suspended from this guide path.

Le volet du dispositif peut se fermer à partir du bas au lieu de à partir du haut lorsque les chemins de guidage s'étendent verticalement.The shutter of the device can close from the bottom instead of from the top when the guideways extend vertically.

Les moyens d'accrochage peuvent être de formes très diverses. Il est par exemple possible de prévoir des pinces aux bords latéraux du volet plutôt qu'à la bande métallique. Les pinces peuvent aussi être remplacées par des bandes constituées d'aimants. En plus, le bourrelet 21 n'est pas nécessairement continu, mais peut, par exemple, être constitué d'une succession de blochets.The attachment means can be of very different shapes. It is for example possible to provide forceps at the side edges of the flap rather than the metal strip. The clamps can also be replaced by bands consisting of magnets. In addition, the bead 21 is not necessarily continuous, but may, for example, consist of a succession of blocks.

En fait, l'invention s'étend à tout dispositif à volet dans lequel des moyens de transmission sont prévus d'une manière détachable entre le volet et les chemins de guidage. Les moyens de transmission ne comprennent pas nécessairement une bande métallique; cette bande peut en effet être réalisé en toute matière, flexible ou rigide, présentant une résistance suffisante.In fact, the invention extends to any shutter device in which transmission means are provided in a detachable manner between the shutter and the guideways. The transmission means do not necessarily include a metal strip; this band can indeed be made of any material, flexible or rigid, having sufficient strength.
