Description

La présente invention est relative à un dispositif de ventilation avec un élément de fermeture rotatif amovible, lequel dispositif comporte une grille avec deux éléments allongés entre lesquels est formée une ouverture et avec deux pièces terminales par lesquelles les éléments sont raccordés, et un élément de fermeture qui est monté de manière à pouvoir tourner dans la grille entre une position de fermeture où il ferme l'ouverture et une position d'aération et qui possède également deux éléments allongés entre lesquels est formée une ouverture et deux pièces terminales par lesquelles les deux éléments sont raccordés, ces pièces terminales comportant chacune un tronçon d'arbre qui s'étend dans l'axe de rotation de l'élément de fermeture et qui est monté dans une pièce terminale de la grille, cette dernière pièce terminale étant dotée d'un guide pour le tronçon d'arbre, l'extrémité de l'ouverture faisant saillie sur un côté extérieur de la grille formant un passage à travers cette grille pour l'élément de fermeture, non compris les pièces terminales, dans la position d'aération.The present invention relates to a ventilation device with a removable rotary closure element, which device comprises a grid with two elongated elements between which an opening is formed and with two end pieces by which the elements are connected, and a closure element which is mounted so as to be able to rotate in the grid between a closed position where it closes the opening and a ventilation position and which also has two elongated elements between which an opening is formed and two end pieces by which the two elements are connected, these end pieces each comprising a shaft section which extends in the axis of rotation of the closure element and which is mounted in an end piece of the grid, this last end piece being provided with a guide for the shaft section, the end of the opening projecting from an outside side of the gr ille forming a passage through this grid for the closure element, not including the end pieces, in the ventilation position.

Un dispositif de ventilation de ce type est décrit dans le document EP-A-0257669. Dans ce dispositif, les tronçons d'axe des pièces terminales de l'élément de fermeture sont aplatis dans la même direction que l'élément de fermeture et les voies de guidage des pièces terminales de la grille sont omises du même côté que la bouche de l'ouverture de la grille. L'élément de fermeture peut être retiré de la grille dans deux positions conjointement avec ses pièces terminales sans que les pièces terminales de la grille doivent être démontées, mais des moyens sont prévus pour bloquer l'élément de fermeture en position d'aération dans la grille. Si l'on veut retirer l'élément de fermeture, on doit l'amener dans une position spéciale différente de la position d'ouverture, ce qui n'est pas possible avec la commande de l'élément de fermeture qui ne peut normalement déplacer cet élément que de la position d'aération à la position de fermeture et vice-versa. Le retrait de l'élément de fermeture n'est donc pas toujours aisé.A ventilation device of this type is described in document EP-A-0257669. In this device, the axis sections of the end pieces of the closure element are flattened in the same direction as the closing element and the guide tracks of the terminal parts of the grid are omitted on the same side as the mouth of the grid opening. The closure element can be removed from the grid in two positions together with its end pieces without the end pieces of the grid having to be disassembled, but means are provided for locking the closure element in the ventilation position in the wire rack. If you want to remove the closing element, you must bring it to a special position different from the opening position, which is not possible with the control of the closing element which cannot normally move this element only from the ventilation position to the closed position and vice versa. The removal of the closure element is therefore not always easy.

Dans le document EP-A-0257669, on décrit une forme de réalisation dans laquelle les moyens précités sont formés par des languettes élastiques prévues dans les pièces terminales de la grille. Dans cette forme de réalisation, l'élément de fermeture peut également être retiré de la grille en position d'aération, mais ces languettes élastiques ne bloquent pas solidement l'élément de fermeture au cours de son fonctionnement normal dans la grille et les tronçon d'arbre de l'élément ne sont soutenus que de manière limitée par le palier formé par les pièces terminales de la grille.In document EP-A-0257669, an embodiment is described in which the above-mentioned means are formed by elastic tongues provided in the end pieces of the grid. In this embodiment, the closing element can also be removed from the grid in the ventilation position, but these elastic tabs do not firmly block the closing element during its normal operation in the grid and the sections d 'shaft of the element are only supported in a limited way by the bearing formed by the end pieces of the grid.

La présente invention a pour objet de remédier à ces inconvénients et de fournir un dispositif de ventilation doté d'un élément de fermeture rotatif amovible, cet élément de fermeture conjointement avec ses tronçons d'arbre étant solidement soutenu dans les pièces terminales de la grille, alors que le retrait de l'élément de fermeture peut encore se faire de manière très aisée.The object of the present invention is to remedy these drawbacks and to provide a ventilation device provided with a removable rotary closing element, this closing element together with its shaft sections being firmly supported in the terminal parts of the grid, while the removal of the closure element can still be done so very easy.

A cet effet, les pièces terminales de la grille comportent chacune au moins deux parties, à savoir une partie fixe qui est raccordée aux éléments allongés de la grille, forme une partie du système de guidage précité sur maximum 180° sur le côté du tronçon d'arbre concerné opposé au côté externe précité de la grille et est dotée sur le côté de ce tronçon d'arbre en regard du côté externe précité de la grille d'un passage pour ce tronçon d'arbre, et une partie amovible qui forme sur ce dernier côté mentionné du tronçon d'arbre une partie complémentaire du système de guidage et maintient de la sorte le tronçon d'arbre à sa place, tandis que des moyens sont prévus pour bloquer cette partie amovible vis-à-vis de la partie fixe.To this end, the terminal parts of the grid each comprise at least two parts, namely a fixed part which is connected to the elongated elements of the grid, forms a part of the above-mentioned guide system over a maximum of 180 ° on the side of the section d 'concerned shaft opposite the aforementioned external side of the grid and is provided on the side of this shaft section opposite the aforementioned external side of the grid with a passage for this section of tree, and a removable part which forms on this last mentioned side of the shaft section a complementary part of the guide system and thus keeps the shaft section in place, while means are provided for locking this removable part with respect to the fixed part .

Dans une forme de réalisation particulière de l'invention, les moyens utilisés pour bloquer la partie amovible vis-à-vis de la partie fixe de la pièce terminale de la grille comportent des éléments qui sont montés eux-mêmes sur au moins l'une des parties.In a particular embodiment of the invention, the means used to block the removable part with respect to the fixed part of the terminal part of the grid include elements which are themselves mounted on at least one Parties.

Ces moyens sont constitués avantageusement d'organes d'encliquetage sur une partie et de nervures sur l'autre partie.These means advantageously consist of snap-fastening members on one part and ribs on the other part.

Dans une forme de réalisation judicieuse de la présente invention, la partie fixe d'une pièce terminale de la grille fait saillie sur le côté opposé au tronçon d'axe à l'extérieur d'une partie de la partie amovible et les moyens comprennent, pour bloquer les parties de cette pièce terminale l'une vis-à-vis de l'autre, une pièce de verrouillage qui est fixée de manière amovible, sur le côté précité de la partie amovible, à la partie saillante de la partie fixe.In a judicious embodiment of the present invention, the fixed part of an end piece of the grid projects on the side opposite to the axis section outside a part of the removable part and the means comprise, to block the parts of this end piece against each other, a locking piece which is removably attached, on the aforementioned side of the removable part, to the projecting part of the fixed part.

Dans une forme de réalisation avantageuse de la présente invention, la partie amovible d'au moins l'une des pièces terminales de la grille est dotée d'une ouverture par laquelle passe un levier de commande raccordé au tronçon d'axe concerné.In an advantageous embodiment of the present invention, the removable part of at least one of the terminal parts of the grid is provided with an opening through which a control lever connected to the concerned axis section passes.

Ce levier de commande est monté dans le tronçon d'axe de préférence de manière amovible.This control lever is mounted in the axis section preferably removably.

Dans une autre forme de réalisation particulière de l'invention, il est agencé par-dessus la bouche - sur le côté extérieur précité de la grille - de l'ouverture formée entre les deux éléments de cette grille, une bande de gaze anti-insectes, qui est disposée avec ses deux bords longitudinaux insérés dans des rainures dont les deux éléments de la grille sont dotés le long de la bouche de l'ouverture.In another particular embodiment of the invention, it is arranged over the mouth - on the aforementioned outer side of the grid - of the opening formed between the two elements of this grid, a strip of anti-insect gauze , which is arranged with its two longitudinal edges inserted in grooves which the two elements of the grid are provided along the mouth of the opening.

De préférence, la partie amovible d'au moins l'une des pièces terminales de la grille est située avec une partie à proximité des extrémités des rainures de telle sorte que cette partie empêche le dégagement de la bande de gaze anti-insectes le long de ces extrémités.Preferably, the removable part of at least one of the end pieces of the grid is located with a part close to the ends of the grooves so that this part prevents the strip of insect-resistant gauze from being released along the these ends.

La présente invention sera à présent décrite plus en détails en se référant à une forme de réalisation préférée sans sortir du cadre de l'invention. Cette forme de réalisation concerne un dispositif de ventilation doté d'un élément de fermeture rotatif amovible selon la description faite en se référant aux dessins ci-annexés dans lesquels :

  • Figure 5 is a sectional view along the line VV of Figure 1; and
  • Figure 6 is a sectional view similar to that of Figure 2, but exploded so as to distinguish the various elements of the device.

Le dispositif de ventilation selon les figures est constitué d'une grille 1 à incorporer dans une structure de fenêtre et dotée d'une ouverture d'aération 2 et d'un élément de fermeture 3 monté de manière à pouvoir tourner dans la grille 1 pour fermer l'ouverture 2.The ventilation device according to the figures consists of a grid 1 to be incorporated into a window structure and provided with a ventilation opening 2 and a closing element 3 mounted so as to be able to rotate in the grid 1 to close the opening 2.

L'élément de fermeture 3 est constitué de deux éléments allongés formés par des profilés métalliques plats 4, entre lesquels est formée une ouverture 5, et de deux pièces terminales 6 en matière plastique qui sont fermement raccordées aux deux profilés 4 précités par l'intermédiaire de saillies collées aux profilés 4.The closure element 3 consists of two elongated elements formed by flat metal sections 4, between which an opening 5 is formed, and two end pieces 6 of plastic material which are firmly connected to the two above-mentioned sections 4 via projections glued to the profiles 4.

Chacune des pièces terminales 6 comporte un tronçon d'arbre tourné vers l'extérieur qui est formé par un collier circulaire 7 qui est concentrique avec l'axe de symétrie de l'élément de fermeture 3 qui est également l'axe de rotation de l'élément 3. Le collier 7 est doté d'un évidement 8 destiné à un levier de commande 9, lequel évidement 8 est circonscrit par un renforcement 10 sur le côté interne du collier.Each of the end pieces 6 comprises a section of shaft facing outwards which is formed by a circular collar 7 which is concentric with the axis of symmetry of the closing element 3 which is also the axis of rotation of the element 3. The collar 7 is provided with a recess 8 intended for a control lever 9, which recess 8 is circumscribed by a reinforcement 10 on the internal side of the collar.

Entre les deux pièces terminales 6 se trouvent deux profilés 4 qui sont encore raccordés l'un à l'autre par un séparateur 11.Between the two end pieces 6 are two sections 4 which are further connected to each other by a separator 11.

La grille 1 est constituée de manière analogue de deux éléments longitudinaux, à savoir un élément supérieur 12 et un élément inférieur 13, entre lesquels est formée l'ouverture d'aération 2 et de deux pièces terminales 14. Chaque pièce terminale 14 est raccordée aux deux éléments 12 et 13 à l'aide de vis 15. Chacun des éléments 12 et 13 est doté d'un système de discontinuité thermique et est constitué en fait de deux profilés séparés l'un de l'autre, 16 et 17, respectivement 18 et 19, qui sont reliés l'un à l'autre par une latte de matière plastique isolante 20.The grid 1 is similarly made up of two longitudinal elements, namely an upper element 12 and a lower element 13, between which is formed the ventilation opening 2 and two end pieces 14. Each end piece 14 is connected to the two elements 12 and 13 using screws 15. Each of elements 12 and 13 is provided with a thermal discontinuity and consists in fact of two sections separated from one another, 16 and 17, respectively 18 and 19, which are connected to each other by an insulating plastic strip 20.

Les pièces terminales 14 bloquent non seulement les deux éléments 12 et 13 l'un vis-à-vis de l'autre, mais forment également des paliers pour les tronçons d'arbre de l'élément de fermeture 3 formés par les colliers 7. Elles possèdent à cet effet un guide annulaire 21 qui est concentrique avec l'axe de rotation de l'élément de fermeture.The end pieces 14 not only block the two elements 12 and 13 with respect to each other, but also form bearings for the shaft sections of the closing element 3 formed by the collars 7. They have for this purpose an annular guide 21 which is concentric with the axis of rotation of the closure element.

A mi-chemin de la longueur de la grille 1 est monté un guide supplémentaire 22 entre les deux éléments 12 et 13, lequel guide coopère avec le séparateur 11 précité de l'élément de fermeture 3. Le côté de guidage de ce guide 22 ne forme qu'une partie de cercle et laisse l'extrémité 23 de l'ouverture d'aération 2 située entre l'élément de fermeture 3 et la bouche complètement libre.Halfway along the length of the grid 1 is mounted an additional guide 22 between the two elements 12 and 13, which guide cooperates with the aforementioned separator 11 of the closing element 3. The guide side of this guide 22 does not forms only part of a circle and leaves the end 23 of the ventilation opening 2 situated between the closing element 3 and the mouth completely free.

Les éléments 12 et 13 et les pièces terminales 14 présentent, sur la périphérie extérieure de la grille, une forme telle que cette grille puisse être aisément montée dans une structure de fenêtre naturellement avec la partie supérieure 12 au-dessus et avec le côté extérieur précité de la grille pratiquement vertical au côté interne de la structure de fenêtre. La bouche de l'ouverture 2 sur l'autre côté de la grille 1 est disposée en dessous, étant donné que, sur cet autre côté, la partie supérieure 12 de la grille forme une coiffe qui va jusqu'à l'arête inférieure de la grille 1.The elements 12 and 13 and the end pieces 14 have, on the outer periphery of the grid, a shape such that this grid can be easily mounted in a window structure naturally with the upper part 12 above and with the above-mentioned external side. from the practically vertical grid to the internal side of the window structure. The mouth of the opening 2 on the other side of the grid 1 is disposed below, since, on this other side, the upper part 12 of the grid forms a cap which goes up to the lower edge of grid 1.

L'extrémité 23 de l'ouverture 2 qui est située entre la bouche de celle-ci sur le côté externe nommé en premier lieu de la grille 1 et l'élément de fermeture 3, possède des dimensions telles qu'elle forme un passage pour l'élément de fermeture 3 sans les pièces terminales 6 et pour la position d'aération, qui est la position présentée dans les figures, dans laquelle les profilés 4 sont disposés horizontalement, mais dans d'autres positions, elle interdit le passage de l'élément de fermeture.The end 23 of the opening 2 which is located between the mouth of the latter on the external side named first of the grid 1 and the element of closure 3, has dimensions such that it forms a passage for the closure element 3 without the end pieces 6 and for the ventilation position, which is the position presented in the figures, in which the profiles 4 are arranged horizontally , but in other positions, it prohibits the passage of the closure element.

Dans la position de fermeture, qui est la position dans laquelle les profilés 4 ont leur surface dirigée verticalement, les deux profilés 4 ferment l'ouverture d'aération 2 complètement. Sur les deux bords longitudinaux, les profilés 4 sont par ailleurs dotés d'une rainure dans laquelle est montée un balai d'étanchéité 24. Dans cette position de fermeture, les deux profilés 4 viennent, par le biais de ces balais 24, en contact avec les bords 25 et 26, respectivement 27 et 28 en sorte que l'écart entre les bords 25 et 26 sur l'arête du côté externe précité de la grille détermine la grandeur du passage précité.In the closed position, which is the position in which the profiles 4 have their surface directed vertically, the two profiles 4 close the ventilation opening 2 completely. On the two longitudinal edges, the profiles 4 are moreover provided with a groove in which is mounted a sealing brush 24. In this closed position, the two profiles 4 come, by means of these brushes 24, into contact with edges 25 and 26, respectively 27 and 28 so that the difference between edges 25 and 26 on the edge of the aforementioned external side of the grid determines the size of the aforementioned passage.

En position d'ouverture ou d'aération, dans laquelle les profilés 4 s'étendent horizontalement, l'ouverture 5 se trouve dans le prolongement de l'ouverture d'aération 2, de telle sorte que l'air passant à travers le dispositif puisse s'écouler tout comme il ressort particulièrement des figures 2 et 3. Dans cette position, seules les pièces terminales 14 de la grille 1 interdisent le retrait de l'élément de fermeture 3. Pour permettre ce retrait, ces pièces terminales sont constituées de deux parties, à savoir une partie fixe 29 qui est fixée aux éléments 12 et 13 par les vis 15 précitées et une partie amovible 10 qui est fixée de manière amovible à la partie fixe 29.In the open or ventilating position, in which the profiles 4 extend horizontally, the opening 5 is in the extension of the ventilation opening 2, so that the air passing through the device can flow as shown in particular in Figures 2 and 3. In this position, only the end pieces 14 of the grid 1 prohibit the removal of the closure element 3. To allow this removal, these end pieces consist of two parts, namely a fixed part 29 which is fixed to the elements 12 and 13 by the aforementioned screws 15 and a removable part 10 which is removably fixed to the fixed part 29.

La partie fixe 29 est constituée, comme on peut le voir surtout dans la figure 6, d'une plaque terminale plane, de nervures qui se trouvent sur cette plaque sur le côté extérieur pour le montage dans la structure de fenêtre, d'un rebord périphérique qui se trouve sur le côté intérieur de la plaque terminale et qui se raccorde aux parties 12 et 13 de la grille 1, mais est interrompu sur le côté extérieur précité, donc à proximité de la bouche de l'ouverture 2, et de nervures qui se trouvent sur le côté intérieur de la plaque terminale pour renforcer et pour bloquer les éléments 12 et 13. Une de ces nervures forme une partie 31, c'est-à-dire en fait la moitié du guide 21 précité pour un collier 27 de l'élément de fermeture 3. Cette partie 31 décrit un demi-cercle et est située complètement sur l'arête du collier 7 opposée à la bouche de l'ouverture 2 ou au côté externe précité de la grille 1. En outre, sur l'arête du côté externe précité, la partie 29 est exempte de nervures en sorte que cette partie 29 forme un passage vers ce côté externe pour le collier 7. Aussi longtemps que la partie amovible 30 n'est pas démontée, le tronçon d'arbre de l'élément de fermeture 3 formé par le collier 7 peut être enlevé de la partie 31 du guide 21 et donc de la pièce terminale 14.The fixed part 29 consists, as can be seen above all in FIG. 6, of an end plate flat, of ribs which are on this plate on the outside side for mounting in the window structure, of a peripheral flange which is on the inside side of the end plate and which connects to parts 12 and 13 of the grid 1, but is interrupted on the above-mentioned outer side, therefore close to the mouth of the opening 2, and of ribs which are located on the inner side of the end plate to reinforce and to block the elements 12 and 13. A of these ribs forms a part 31, that is to say in fact half of the aforementioned guide 21 for a collar 27 of the closing element 3. This part 31 describes a semicircle and is situated completely on the edge of the collar 7 opposite the mouth of the opening 2 or the aforementioned external side of the grid 1. In addition, on the edge of the aforementioned external side, the part 29 is free of ribs so that this part 29 forms a passage to this external side for the e collar 7. As long as the removable part 30 is not dismantled, the shaft section of the closing element 3 formed by the collar 7 can be removed from the part 31 of the guide 21 and therefore from the end piece 14.

La partie amovible 30 de chaque pièce terminale 14 forme une fermeture pour le passage précité ainsi que le reste du guide 21. Comme on peut surtout le voir dans la figure 6, la partie amovible 30 comporte une partie de forme semi-circulaire 32 qui constitue donc l'autre moitié du guide 21. Cette partie 32 est dotée, à mi-chemin de l'arc qu'elle décrit, d'une ouverture allongée 33 pour le levier de commande 9. Aux deux extrémités de l'ouverture 33 sur le côté convexe de cette partie 32, se trouve une partie de butée 34 pour le levier 9. Entre autres à titre de renforcement, une partie ronde 35 de même diamètre que le collier 7 se raccorde à la première arête et au côté creux de la partie 32 du guide 21. Lors de la mise en place de la partie amovible 30, cette partie ronde 35 est fichée entre le collier 7 et la partie terminale plane de la partie fixe 29 jusque contre la partie 32 du guide 21. Sur l'autre arête, sur le côté convexe de la partie 32, se raccorde un bord 36 qui, lorsque la partie amovible 30 est installée en place, s'étend jusqu'au côté extérieur précité de la grille 1. Par ailleurs, la partie 30 est dotée sur les deux côtés, à proximité de la partie ronde 35 et des parties de butée 34 qui s'y raccordent, d'un membre élastique 37 épaissi à son extrémité. Les deux membres 37 forment des organes d'encliquetage qui, lorsque la partie 30 est en place, s'accrochent par leur extrémité répaissie derrière les nervures 38 qui se trouvent sur le côté intérieur de la partie terminale plane de la partie fixe 30.The removable part 30 of each end piece 14 forms a closure for the aforementioned passage as well as the rest of the guide 21. As can be seen above in FIG. 6, the removable part 30 comprises a part of semi-circular shape 32 which constitutes therefore the other half of the guide 21. This part 32 is provided, at the halfway point of the arc which it describes, with an elongated opening 33 for the control lever 9. At the two ends of the opening 33 on the convex side of this part 32 is an abutment part 34 for the lever 9. Among other things as reinforcement, a round part 35 of the same diameter as the collar 7 is connected to the first edge and to the hollow side of the part 32 of the guide 21. When the removable part 30 is put in place, this round part 35 is inserted between the collar 7 and the flat end portion of the fixed portion 29 up to the portion 32 of the guide 21. On the other edge, on the convex side of the portion 32, is connected an edge 36 which, when the removable portion 30 is installed in place , extends to the aforementioned outer side of the grid 1. Furthermore, the part 30 is provided on both sides, near the round part 35 and the abutment parts 34 which are connected to it, with a elastic member 37 thickened at its end. The two members 37 form latching members which, when the part 30 is in place, hook by their thickened end behind the ribs 38 which are on the inside of the flat end part of the fixed part 30.

Bien que, grâce aux membres 37, la partie amovible 30 de chaque pièce terminale 14 soit déjà bloquée à sa place, il est encore prévu une pièce de verrouillage qui est constituée d'une plaquette allongée 39 dotée de deux broches 40. Un côté de la plaquette 39 a une découpe de forme arquée et s'adapte sur un rebord de la partie courbe 32 du guide 21 situé à proximité de l'ouverture 33. Les deux broches 40 s'ajustent dans des ouvertures 41 ménagées dans une partie de la plaque terminale plane de la partie fixe 29 qui fait saillie en dehors de cette partie courbe 32. Lorsque cette plaquette 39, qui se trouve sur le côté intérieur de la plaque terminale précitée, s'ajuste dans les ouvertures 41 avec ses broches 40, son rebord courbe s'appuie contre le rebord précité de la partie courbe 32 et la partie amovible 30 ne peut plus se dégager de la partie fixe 29 de la pièce terminale 14.Although, thanks to the members 37, the removable part 30 of each end piece 14 is already locked in place, there is also provided a locking piece which consists of an elongated plate 39 provided with two pins 40. One side of the wafer 39 has an arcuate cutout and fits on a rim of the curved part 32 of the guide 21 located near the opening 33. The two pins 40 fit into openings 41 formed in part of the flat end plate of the fixed part 29 which projects outside this curved part 32. When this plate 39, which is on the inside of the aforementioned end plate, fits in the openings 41 with its pins 40, its curved edge rests against the aforementioned edge of the curved part 32 and the removable part 30 can no longer disengage from the part fixed 29 of the end piece 14.

La bouche de l'ouverture 2 sur le côté extérieur précité de la grille 1 est encore fermée par une bande 42 de gaze anti-insectes. Cette bande est glissée par ses deux bords longitudinaux dans des rainures 43 qui sont formées de part et d'autre de la bouche dans les éléments 12 et 13 de la grille 1. Les bords 36 des parties amovibles 30 s'étendent jusqu'à proximité des extrémités de ces rainures 43. Le bord 36 de la première pièce terminale 14 est fermé et obture une extrémité des rainures 43 de telle sorte que la bande 42 ne puisse se glisser hors des rainures. Le rebord 36 de l'autre pièce terminale 14 est par contre dotée d'une gorge 44 qui est située en regard des autres extrémités des rainures 43 et par laquelle la bande 42 peut être glissée. Le dégagement à travers cette gorge 44 de la bande 42 est cependant, lorsque le dispositif de ventilation est complètement démonté, interdit par le levier 9 qui s'engage à travers l'ouverture 33 dans la partie amovible 30 de cette pièce terminale 14.The mouth of the opening 2 on the above-mentioned outer side of the grid 1 is still closed by a strip 42 of insect-proof gauze. This strip is slid by its two longitudinal edges into grooves 43 which are formed on either side of the mouth in the elements 12 and 13 of the grid 1. The edges 36 of the removable parts 30 extend to the vicinity ends of these grooves 43. The edge 36 of the first end piece 14 is closed and closes one end of the grooves 43 so that the strip 42 cannot slip out of the grooves. The rim 36 of the other end piece 14 is on the other hand provided with a groove 44 which is situated opposite the other ends of the grooves 43 and by which the strip 42 can be slid. The release through this groove 44 of the strip 42 is however, when the ventilation device is completely disassembled, prohibited by the lever 9 which engages through the opening 33 in the removable part 30 of this end piece 14.

Ce levier de commande 9, tout comme d'ailleurs également l'autre levier de commande, possède à une extrémité deux membres élastiques dotés d'épaississements en sorte que ces leviers 9, comme on peut le voir nettement dans la figure 5, puissent être encliquetés dans cette pièce terminale 14 à travers l'ouverture 33 de la pièce terminale correspondante 14, l'évidement 8 et entre les renforcements 10 du collier 7. Aux deux extrémités du dispositif, le levier de commande 9, qui est contenu entre un bord 36 de la partie amovible 30 et la plaquette 39 de la pièce de verrouillage 39, 40, interdit tout déplacement dans la direction axiale et donc le desserrage de la pièce de verrouillage 39, 40.This control lever 9, just like also the other control lever, has at one end two elastic members provided with thickenings so that these levers 9, as can be clearly seen in FIG. 5, can be snapped into this end piece 14 through the opening 33 of the corresponding end piece 14, the recess 8 and between the reinforcements 10 of the collar 7. At the two ends of the device, the control lever 9, which is contained between an edge 36 of the removable part 30 and the plate 39 of the locking piece 39, 40, prohibits any movement in the axial direction and therefore the loosening of the locking piece 39, 40.

En regard du séparateur 11, entre les éléments 12 et 13 de la grille 1, est montée une petite latte 45 qui s'étend en oblique par-dessus la bouche de l'ouverture 2. Cette latte 45 se trouve avec ses extrémités glissées dans les rainures 46 qui s'étendent le long des rainures 43 dans les éléments 12 et 13. Les rainures 43 et 46 donnent l'une sur l'autre.Opposite the separator 11, between the elements 12 and 13 of the grid 1, is mounted a small slat 45 which extends obliquely over the mouth of the opening 2. This slat 45 is located with its ends slid in the grooves 46 which extend along the grooves 43 in the elements 12 and 13. The grooves 43 and 46 face one another.

En fonctionnement normal, les tronçons d'arbre de l'élément de fermeture 3 formés par les colliers 7 sont solidement fixés et efficacement soutenus dans la grille 1. Mais il est très facile de retirer la bande 42. Il suffit de retirer le levier de commande encliqueté 9 sur le côté avec la pièce terminale 14 dotée de la gorge 44, après quoi la bande 42 peut être glissée hors de son logement par cette gorge. De même, le retrait de l'élément de fermeture 3 est aisé. Après avoir retiré la bande 42 et les deux leviers de commande 9, on écarte les pièces de verrouillage 39, 40 et l'on décliquète également par traction les deux parties amovibles 30 des parties fixes 29. Enfin, on fait glisser la latte 45 hors des rainures 46 et on retire l'élément de fermeture 3 que l'on a placé au départ dans la position d'aération à l'aide du levier 9, hors de la grille 1. Le remontage du dispositif de ventilation se fait en suivant les mêmes étapes, mais dans l'ordre inverse.In normal operation, the shaft sections of the closure element 3 formed by the collars 7 are solidly fixed and effectively supported in the grid 1. But it is very easy to remove the strip 42. It suffices to remove the lever from control snapped onto the side with the end piece 14 provided with the groove 44, after which the strip 42 can be slid out of its housing by this groove. Likewise, the removal of the closure element 3 is easy. After removing the strip 42 and the two control levers 9, the locking parts 39, 40 are moved aside and the two removable parts 30 are also unlatched from the fixed parts 29. Finally, the slat 45 is slid out grooves 46 and the closing element 3 is removed, which was initially placed in the ventilation position using the lever 9, outside the grid 1. The reassembly of the ventilation device is carried out as follows the same steps, but in reverse order.
