Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention se rapporte au domaine général des volets roulants ou similaires contenus dans un coffre. Elle vise plus précisément un coffre pour volet roulant ou similaire présentant un accès par le dessous de grande dimensions.The present invention relates to the general field of roller shutters or the like contained in a trunk. It aims more precisely at a box for roller shutter or similar having access from below of large dimensions.

Etat de la techniqueState of the art

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

En référence à la figure 1, ce type de coffre CO connu est destiné à être implanté dans une habitation au-dessus d'un dormant DO recevant un ouvrant OU tel qu'une fenêtre ou une porte, et étant fixé dans une embrasure EM par l'intermédiaire de pattes de fixation et des moyens d'ancrage. Ledit coffre CO est de manière classique fixé à l'intérieur de l'habitation contre un linteau LI de ladite embrasure EM par l'intermédiaire de pattes de scellement et sur le dessus de la traverse supérieure du dormant DO. Dans cette configuration, ledit coffre CO est généralement au moins en partie noyé dans le linteau LI ou l'isolation IS intérieure de ladite habitation, afin de le rendre peu ou pas visible.In reference to the figure 1 , this type of known CO box is intended to be installed in a home above a frame DO receiving an opening OR such as a window or a door, and being fixed in an embrasure EM via lugs fixing and anchoring means. Said box CO is conventionally fixed inside the house against a lintel LI of said embrasure EM via sealing tabs and on top of the upper crosspiece of the frame DO. In this configuration, said CO box is generally at least partly embedded in the lintel LI or the interior IS insulation of said home, in order to make it little or not visible.

Ce type coffre CO est classiquement réalisé par assemblage de planches ou panneaux en polychlorure de vinyle (PVC) et comprend au moins des planches arrière AR, supérieure SU, avant AV et inférieure IN. Ce type de coffre comporte en outre un accès AC au niveau de sa planche inférieure IN, nommé accès sous-face, pour pouvoir intervenir à l'intérieur dudit coffre CO en vue notamment d'opérations de maintenance sur l'arbre d'enroulement.This type of CO box is conventionally made by assembling polyvinyl chloride (PVC) boards or panels and includes at least rear AR, upper SU, front AV and lower IN boards. This type of box also includes an access AC at the level of its lower board IN, called underside access, to be able to work inside said box CO in particular with a view to maintenance operations on the winding shaft.

Bien qu'a priori utile, cette configuration n'est pas totalement pratique car la largeur L de l'accès AC est limitée car elle est dépendante notamment de l'épaisseur E de l'ensemble dormant DO - OU (Cf. figure 1). Par ailleurs, la largeur L dépend aussi de la fixation de l'accès AC, qui doit d'être suffisamment solide pour que ledit de accès AC ne tombe pas au moindre coup de vent. En général, la fixation de l'accès AC est obtenue par clipsage ou vissage dudit accès AC le long de chacun de ses bords longitudinaux. Pour mettre en place ou retirer les vis ou clips, on comprend bien qu'il est nécessaire de prévoir des aménagements sur le coffre CO, ces derniers étant souvent proéminents et empiétant sur la largeur L.Although a priori useful, this configuration is not entirely practical because the width L of the access AC is limited because it is dependent in particular on the thickness E of the DO - OU frame assembly (Cf. figure 1 ). Furthermore, the width L also depends on the fixing of the AC access, which must be sufficiently solid so that said AC access does not fall in the slightest gust of wind. In general, fixing the AC access is obtained by clipping or screwing said AC access along each of its longitudinal edges. To install or remove the screws or clips, we understand that it is necessary to provide arrangements on the CO box, the latter often being prominent and encroaching on the width L.

Il existe également des coffres semblables à ceux divulgués dans les demandes de brevet européen EP 1 835 122 , EP 1 705 336 et EP 2 255 058 . Toutefois, ces coffres ne sont pas faciles à mettre en oeuvre.There are also vaults similar to those disclosed in European patent applications EP 1 835 122 , EP 1 705 336 And EP 2 255 058 . However, these chests are not easy to implement.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de proposer une alternative aux coffres pour volets roulants ou similaires présentant un accès par le dessous, résistant, facile à mettre en oeuvre et permettant un accès aisé et suffisamment large pour intervenir facilement à l'intérieur dudit coffre notamment pour des opérations de maintenance, sans empiéter dans l'espace interne dudit coffre.The aim of the present invention is to propose an alternative to boxes for rolling shutters or the like having access from below, resistant, easy to implement and allowing easy access and wide enough to easily work inside said box in particular for maintenance operations, without encroaching into the internal space of said trunk.

Conformément à l'invention, il est donc proposé un coffre pour volet roulant ou similaire présentant un accès par le dessous et comprenant au moins une planche arrière, une planche supérieure, une planche avant et une planche inférieure, cette dernière comportant au moins :

  • une portion fixe agencée pour être fixée sur le dessus d'un dormant,
  • une ouverture entre ladite portion fixe et ladite planche avant, et
  • une trappe d'accès amovible comblant ou non ladite ouverture, ledit coffre étant remarquable en ce que ladite planche inférieure comporte au moins un organe de liaison fixé de façon amovible sur un bord longitudinal avant de la portion fixe, et sur lequel se solidarise de manière amovible ladite trappe d'accès par son bord longitudinal arrière.
In accordance with the invention, there is therefore proposed a box for a roller shutter or the like having access from below and comprising at least one rear board, an upper board, a front board and a lower board, the latter comprising at least:
  • a fixed portion arranged to be fixed on the top of a frame,
  • an opening between said fixed portion and said front board, and
  • a removable access hatch filling or not filling said opening, said trunk being remarkable in that said lower board comprises at least one connecting member removably fixed on a front longitudinal edge of the fixed portion, and on which is secured in a manner removable said access hatch by its rear longitudinal edge.

Le bord longitudinal avant est muni d'une languette fixe issue de l'arrête externe dudit longitudinal avant et s'étendant dans le prolongement de la face externe de la portion fixe.The front longitudinal edge is provided with a fixed tongue coming from the external edge of said front longitudinal and extending in the extension of the external face of the fixed portion.

Le bord longitudinal avant est muni d'une languette mobile montée pivotante sur l'arrête interne dudit longitudinal avant entre une position "droite" dans laquelle elle s'étend dans le prolongement de la face externe de la portion fixe, et une position "inclinée" dans laquelle elle vient en appui contre le bord longitudinal avant.The front longitudinal edge is provided with a movable tongue pivotally mounted on the internal edge of said front longitudinal between a "straight" position in which it extends in the extension of the external face of the fixed portion, and an "inclined" position in which it bears against the front longitudinal edge.

De manière avantageuse, l'organe de liaison s'étend sur toute la longueur du bord longitudinal avant de la portion fixe.Advantageously, the connecting member extends over the entire length of the front longitudinal edge of the fixed portion.

Selon un autre mode de réalisation, la planche inférieure comporte au moins deux organes de liaison disposés le long du bord longitudinal avant de sa portion fixe.According to another embodiment, the lower board comprises at least two connecting members arranged along the front longitudinal edge of its fixed portion.

Selon un mode de réalisation avantageux, la trappe d'accès est solidarisée sur l'organe de liaison selon une liaison pivot autour d'un axe de pivotement parallèle à l'arrête interne dudit bord longitudinal avant et l'organe de liaison comprend au moins :

  • une aile verticale destinée à venir en appui contre le bord longitudinal avant,
  • une aile horizontale issue de l'extrémité supérieure de ladite aile verticale et s'étendant parallèlement à la face interne de la portion fixe, lorsque ladite aile verticale est en appui contre le bord longitudinal avant, et
  • un premier rebord issu de la face avant de son aile verticale et s'étendant dans la même direction que son aile horizontale, ledit premier rebord recevant le long de son extrémité libre une portion de cylindre élastiquement déformable, l'axe longitudinal de cette dernière déterminant l'axe de pivotement de la liaison pivot entre l'organe de liaison et la trappe d'accès.
According to an advantageous embodiment, the access hatch is secured to the connecting member in a pivot connection around a pivot axis parallel to the internal edge of said front longitudinal edge and the connecting member comprises at least :
  • a vertical wing intended to come to rest against the front longitudinal edge,
  • a horizontal wing coming from the upper end of said vertical wing and extending parallel to the internal face of the fixed portion, when said vertical wing is resting against the front longitudinal edge, and
  • a first rim coming from the front face of its vertical wing and extending in the same direction as its horizontal wing, said first rim receiving along its free end an elastically deformable cylinder portion, the longitudinal axis of the latter determining the pivot axis of the pivot connection between the connecting member and the access hatch.

De manière avantageuse, l'aile verticale de l'organe de liaison a une forme congruente à celle du bord longitudinal avant de la portion fixe de la planche inférieure.Advantageously, the vertical wing of the connecting member has a shape congruent to that of the front longitudinal edge of the fixed portion of the lower board.

La trappe d'accès comporte de préférence une rainure longitudinale aménagée le long de son bord longitudinal arrière, ladite rainure longitudinale ayant la section transversale de forme congruente à celle de la portion de cylindre associée au premier rebord de l'aile verticale de l'organe de liaison afin de permettre la liaison pivot.The access hatch preferably comprises a longitudinal groove arranged along its rear longitudinal edge, said longitudinal groove having the cross section of shape congruent to that of the cylinder portion associated with the first edge of the vertical wing of the member connection to allow the pivot connection.

Les arbre d'enroulement, tablier et coulisses de guidage ne sont également pas représentés sur les figures afin de ne pas les surchargerSaid box 1 contains, in a conventional manner, a winding shaft, not shown, resting at its ends on bearings secured to said box 1 and to which is attached an apron formed of horizontal blades articulated together and whose ends move vertically at inside guide slides integral with the associated frame or said embrasure surrounding said frame 2. The winding shaft, apron and guide slides are also not shown in the figures so as not to overload them

On décrit dans ce qui suit, un coffre 1 disposé horizontalement, toutefois ledit coffre 1 pourra être plus ou moins incliné par rapport à l'horizontale les termes tels que, par exemple, horizontal, vertical, inférieur ou encore supérieur seront alors à adapter.We describe in what follows, a chest 1 arranged horizontally, however said chest 1 may be more or less inclined relative to the horizontal, terms such as, for example, horizontal, vertical, lower or even higher will then have to be adapted.

Ainsi, ledit coffre 1 est réalisé par assemblage de planches ou panneaux, de préférence en polychlorure de vinyle (PVC), et comprend au moins une planche arrière 3, une planche supérieure 4, une planche avant 5 et une planche inférieure 6, ces dernières déterminant entre elles un volume interne 7.Thus, said trunk 1 is made by assembling boards or panels, preferably made of polyvinyl chloride (PVC), and comprises at least a rear board 3, an upper board 4, a front board 5 and a lower board 6, the latter determining between them an internal volume 7.

On désigne ici par "arrière" tout élément ou partie d'élément du coffre 1 selon l'invention disposé du côté de l'embrasure et par "avant" tout élément ou partie d'élément dudit coffre 1 disposé du côté opposé, c'est-à-dire du côté intérieur de l'habitation.Here we designate by "rear" any element or part of an element of the trunk 1 according to the invention placed on the side of the embrasure and by "front" any element or part of an element of said trunk 1 placed on the opposite side, it is that is to say on the interior side of the house.

Par ailleurs, on désigne ici par "interne" tout élément ou partie d'élément du coffre 1 situé du côté du volume interne 7 situé entre les planches arrière 3, supérieure 4, avant 5 et inférieure 6 et par "externe" tout élément ou partie d'élément dudit coffre 1 situé du côté opposé audit volume interne 7.Furthermore, here we designate by "internal" any element or part of an element of the trunk 1 located on the side of the internal volume 7 located between the rear 3, upper 4, front 5 and lower 6 boards and by "external" any element or element part of said trunk 1 located on the side opposite said internal volume 7.

La planche inférieure 6 comporte une portion fixe 8 fixée sur le dessus du dormant 2, avantageusement par l'intermédiaire d'une bride d'inertie 9 et une ouverture 10 entre ladite portion fixe 8 et la planche avant 5 du coffre 1.The lower board 6 comprises a fixed portion 8 fixed on the top of the frame 2, advantageously via an inertia flange 9 and an opening 10 between said fixed portion 8 and the front board 5 of the trunk 1.

Selon un mode de réalisation particulier, ladite portion fixe 8 comprend au moins une languette fixe 12 issue de l'arrête externe d'un longitudinal avant 11 et s'étendant dans le prolongement de la face externe de ladite portion fixe 8.According to a particular embodiment, said fixed portion 8 comprises at least one fixed tongue 12 coming from the external edge of a front longitudinal 11 and extending in the extension of the external face of said fixed portion 8.

Selon un autre mode de réalisation particulier, ladite portion fixe 8 comprend en outre une languette mobile 13 montée pivotante sur l'arrête interne dudit longitudinal avant 11 entre une position "droite" dans laquelle elle s'étend dans le prolongement de la face interne de la portion fixe 8 (Cf. figure 5), et une position "inclinée" dans laquelle elle vient en appui contre le longitudinal avant 11 et, le cas échéant, contre l'extrémité libre de ladite languette fixe 12 (Cf. figure 6).According to another particular embodiment, said fixed portion 8 further comprises a movable tongue 13 pivotally mounted on the internal edge of said front longitudinal 11 between a "straight" position in which it extends in the extension of the internal face of the fixed portion 8 (Cf. Figure 5 ), and an "inclined" position in which it comes to rest against the front longitudinal 11 and, where appropriate, against the free end of said fixed tongue 12 (Cf. Figure 6 ).

Pour des raisons qui seront expliquées plus loin, le bord longitudinal avant 11 présente avantageusement une zone médiane en saillie en direction de l'ouverture 10. Pour cela, ledit bord longitudinal avant 11 a de préférence une section transversale en forme globale de V ou en T pivoté de 90° sur la gauche.For reasons which will be explained later, the front longitudinal edge 11 advantageously has a median zone projecting towards the opening 10. For this, said front longitudinal edge 11 preferably has a cross section in the overall shape of a V or T rotated 90° to the left.

La planche inférieure 6 comporte en outre au moins :

  • une trappe d'accès 14 amovible destinée à combler l'ouverture 10 située entre sa portion fixe 8 et la planche avant 5 du coffre 1, et
  • un organe de liaison 15 fixé de façon amovible sur le bord longitudinal avant 11 de sa portion fixe 8, le cas échéant entre la languette fixe 12 et la languette mobile 13 en position droite, et sur lequel se solidarise de manière amovible ladite trappe d'accès 14 par son bord longitudinal arrière 16.
The lower board 6 further comprises at least:
  • a removable access hatch 14 intended to fill the opening 10 located between its fixed portion 8 and the front board 5 of the trunk 1, and
  • a connecting member 15 fixed removably on the front longitudinal edge 11 of its fixed portion 8, where appropriate between the fixed tongue 12 and the movable tongue 13 in upright position, and on which said access hatch 14 is removably secured by its rear longitudinal edge 16.

Selon un mode de réalisation particulier, la trappe d'accès 14 est solidarisée sur l'organe de liaison 15 selon une liaison pivot autour d'un axe de pivotement 17 (Cf. figure 8) parallèle à l'arrête interne dudit bord longitudinal avant 11 de ladite portion fixe 8.According to a particular embodiment, the access hatch 14 is secured to the connecting member 15 according to a pivot connection around a pivot axis 17 (Cf. figure 8 ) parallel to the internal edge of said front longitudinal edge 11 of said fixed portion 8.

Dans cette hypothèse, la trappe d'accès 14 est apte à pivoter autour de l'axe de pivotement 17 entre une position "fermée" dans laquelle elle comble l'ouverture 10 et une position "ouverte" dans laquelle elle dégage au moins en partie ladite ouverture 10.In this hypothesis, the access hatch 14 is able to pivot around the pivot axis 17 between a "closed" position in which it fills the opening 10 and an "open" position in which it clears at least partially said opening 10.

Ledit organe de liaison 15 a alors avantageusement une forme générale de cornière et comprend :

  • une aile verticale 18 destinée à venir en appui contre le bord longitudinal avant 11 de la portion fixe 8 de la planche inférieure 6, et
  • une aile horizontale 19 issue de l'extrémité supérieure de ladite aile verticale 18 et s'étendant parallèlement à la face interne de la portion fixe 8, lorsque ladite aile verticale 18 est en appui contre le bord longitudinal avant 11.
Said connecting member 15 then advantageously has the general shape of an angle and comprises:
  • a vertical wing 18 intended to come to bear against the front longitudinal edge 11 of the fixed portion 8 of the lower board 6, and
  • a horizontal wing 19 coming from the upper end of said vertical wing 18 and extending parallel to the internal face of the fixed portion 8, when said vertical wing 18 bears against the front longitudinal edge 11.

L'aile verticale 18 de l'organe de liaison 15 a de préférence une forme congruente à celle du bord longitudinal avant 11 de la portion fixe 8 de la planche inférieure 6. Ainsi, si le bord longitudinal avant 11 présente une zone médiane en saillie en direction de l'ouverture 10, l'aile verticale 18 de l'organe de liaison 15 est alors telle qu'au moins sa face arrière présente une zone médiane en creux. On comprend que cette configuration particulière permet de faciliter la mise en place, le maintien et la fixation de l'organe de liaison 15 sur ladite portion fixe 8.The vertical wing 18 of the connecting member 15 preferably has a shape congruent to that of the front longitudinal edge 11 of the fixed portion 8 of the lower board 6. Thus, if the front longitudinal edge 11 has a projecting middle zone in the direction of the opening 10, the vertical wing 18 of the connecting member 15 is then such that at least its rear face has a recessed middle zone. It is understood that this particular configuration makes it possible to facilitate the installation, maintenance and fixing of the connecting member 15 on said fixed portion 8.

Ledit organe de liaison 15 comporte également un premier rebord 20 issu de la face avant de son aile verticale 18 et s'étendant dans la même direction que son aile horizontale 19, ledit premier rebord 20 recevant le long de son extrémité libre une portion de cylindre 21, l'axe longitudinal de cette dernière déterminant l'axe de pivotement 17 de la liaison pivot entre l'organe de liaison 15 et la trappe d'accès 14. Ladite portion de cylindre 21 est élastiquement déformable et avantageusement un cylindre de révolution, c'est-à-dire que sa section transversale a une forme circulaire.Said connecting member 15 also comprises a first rim 20 coming from the front face of its vertical wing 18 and extending in the same direction as its horizontal wing 19, said first rim 20 receiving along its free end a portion of cylinder 21, the longitudinal axis of the latter determining the pivot axis 17 of the pivot connection between the connecting member 15 and the access hatch 14. Said cylinder portion 21 is elastically deformable and advantageously a cylinder of revolution, that is, its cross section has a circular shape.

Ledit organe de liaison 15 est fixé contre le bord longitudinal avant 11 de sa portion fixe 8 par tous moyens de fixation 22 adaptés tels que, par exemple, des vis autoperceuses, comme représenté sur les figures, des clips, ou encore des ensembles clameau - écrou.Said connecting member 15 is fixed against the front longitudinal edge 11 of its fixed portion 8 by any suitable fixing means 22 such as, for example, screws self-drilling machines, as shown in the figures, clips, or even clamp - nut assemblies.

Selon un autre mode de réalisation non représenté, l'organe de liaison 15 comporte en plus des éléments précédemment décrits une autre aile horizontale issue de l'extrémité inférieure de l'aile verticale 18 et s'étendant parallèlement à la face externe de la portion fixe 8, lorsque ladite aile verticale 18 est en appui contre le bord longitudinal avant 11 de ladite portion fixe 8. Dans cette configuration, l'organe de liaison 15 a alors une forme générale de C, l'autre aile horizontale remplaçant alors la languette fixe 12 de la portion fixe 8.According to another embodiment not shown, the connecting member 15 comprises, in addition to the elements previously described, another horizontal wing coming from the lower end of the vertical wing 18 and extending parallel to the external face of the portion fixed 8, when said vertical wing 18 bears against the front longitudinal edge 11 of said fixed portion 8. In this configuration, the connecting member 15 then has a general C shape, the other horizontal wing then replacing the tongue fixed 12 of the fixed portion 8.

Par ailleurs, selon un mode de réalisation avantageux et en référence à la figure 3, l'aile verticale 18 de l'organe de liaison 15 comporte sur sa face interne un organe d'accouplement apte à coopérer avec un organe d'accouplement complémentaire disposé sur la languette mobile 13 de la portion fixe 8 pour assurer une liaison mécanique entre l'organe de liaison 15 et ladite languette mobile 13. L'organe d'accouplement est de préférence un deuxième rebord 23 issu de l'extrémité libre de ladite aile horizontale 19 et s'étendant dans la direction opposée à l'aile verticale 18 associée, ledit deuxième rebord 23 ayant une section transversale en forme de T. L'organe d'accouplement complémentaire est de préférence un rebord 24 issu de la face externe de ladite la languette mobile 13 et s'étendant en direction de la languette fixe 12, ledit rebord 24 ayant une section transversale en forme de L.Furthermore, according to an advantageous embodiment and with reference to the Figure 3 , the vertical wing 18 of the connecting member 15 comprises on its internal face a coupling member capable of cooperating with a complementary coupling member disposed on the movable tongue 13 of the fixed portion 8 to ensure a mechanical connection between the connecting member 15 and said movable tongue 13. The coupling member is preferably a second rim 23 coming from the free end of said horizontal wing 19 and extending in the direction opposite to the vertical wing 18 associated, said second rim 23 having a T-shaped cross section. The complementary coupling member is preferably a rim 24 coming from the external face of said movable tongue 13 and extending in the direction of the fixed tongue 12 , said rim 24 having an L-shaped cross section.

On comprend bien que les organes d'accouplement et d'accouplement complémentaire pourront être d'un tout autre type tel que, par exemple des rainures en queue d'aronde, sans sortir du cadre de la présente invention.It is clearly understood that the coupling and complementary coupling members could be of a completely different type such as, for example, dovetail grooves, without departing from the scope of the present invention.

En outre, la planche inférieure 6 comporte avantageusement un seul organe de liaison 15 s'étendant sur toute la longueur du bord longitudinal avant 11 de sa portion fixe 8 (Cf. figure 8). Toutefois, sans sortir du cadre de la présente invention, la planche inférieure 6 pourra comporter au moins deux organes de liaison 15 disposés le long du bord longitudinal avant 11 de sa portion fixe 8, chaque organe de liaison 15 étant alors de longueur plus réduite (Cf. figure 9). Dans cette dernière hypothèse, la portion fixe 8 comprendra nécessairement au moins une languette mobile 13 montée pivotante sur l'arrête interne de son longitudinal avant 11 afin d'assurer la continuité d'étanchéité entre ladite portion fixe 8 et la trappe d'accès 14 et de part et d'autre de chacun des au moins deux organes de liaison 15, tout en permettant d'augmenter la largeur de passage au niveau de l'ouverture 10.In addition, the lower board 6 advantageously comprises a single connecting member 15 extending over the entire length of the front longitudinal edge 11 of its fixed portion 8 (Cf. figure 8 ). However, without departing from the scope of the present invention, the lower board 6 may comprise at least two connecting members 15 arranged along the front longitudinal edge 11 of its fixed portion 8, each connecting member 15 then being of shorter length ( See Figure 9 ). In this last hypothesis, the fixed portion 8 will necessarily include at least one movable tongue 13 pivotally mounted on the internal edge of its front longitudinal 11 in order to ensure the continuity of sealing between said fixed portion 8 and the access hatch 14 and on either side of each of the at least two connecting members 15, while allowing the passage width to be increased at the level of the opening 10.

Pour assurer la liaison pivot, la trappe d'accès 14 comporte une rainure longitudinale 25 aménagée le long de son bord longitudinal arrière 16, ladite rainure longitudinale 25 ayant la section transversale de forme congruente à celle de la portion de cylindre 21 associée au premier rebord 20 de l'aile verticale 18 de l'organe de liaison 15 afin de permettre la liaison pivot. Par ailleurs, lorsque la trappe d'accès 14 coopère avec l'organe de liaison 15, cette dernière obture totalement l'ouverture 10 et est fixée le long de son bord longitudinal avant 26 sur la planche avant 5 dudit coffre 1 à l'aide d'organes de fixation, non représentés, tels que, par exemple, des vis, des boulons ou encore des clips. Afin de ne pas obstruer l'ouverture 10, les organes de fixation sont disposés à l'extérieur du coffre 1 selon l'invention.To ensure the pivot connection, the access hatch 14 comprises a longitudinal groove 25 arranged along its rear longitudinal edge 16, said longitudinal groove 25 having the cross section of shape congruent to that of the cylinder portion 21 associated with the first rim 20 of the vertical wing 18 of the connecting member 15 in order to allow the pivot connection. Furthermore, when the access hatch 14 cooperates with the connecting member 15, the latter completely closes the opening 10 and is fixed along its front longitudinal edge 26 on the front board 5 of said trunk 1 using fixing members, not shown, such as, for example, screws, bolts or even clips. In order not to obstruct the opening 10, the fixing members are arranged outside the box 1 according to the invention.

Enfin, pour des raisons évidentes d'isolation thermique et acoustique, le coffre 1 selon l'invention comporte avantageusement au moins un isolant 27 disposé dans son volume interne 7 en appui contre la planche avant 5 et au moins en partie contre les planches supérieure 4 et inférieure 6. Pour faciliter le retrait dudit isolant 27 lors des opérations de maintenance, ce dernier se compose avantageusement d'un bloc supérieur 27A et d'un bloc inférieur 27B réalisés en polystyrène expansé (PSE).Finally, for obvious reasons of thermal and acoustic insulation, the box 1 according to the invention advantageously comprises at least one insulator 27 placed in its internal volume 7 bearing against the front board 5 and at least partly against the upper boards 4 and lower 6. To facilitate the removal of said insulator 27 during maintenance operations, the latter advantageously consists of an upper block 27A and a lower block 27B made of expanded polystyrene (PSE).

Avec la configuration précédente décrite, pour accéder au volume interne 7 du coffre 1 selon l'invention, on procède de la manière décrite ci-après.With the previous configuration described, to access the internal volume 7 of the trunk 1 according to the invention, we proceed in the manner described below.

Le coffre 1 selon l'invention est tel que représenté à la figure 2, c'est-à-dire que l'organe de liaison 15 est fixé sur le bord longitudinal avant 11 de la portion fixe 8 de la planche inférieure 6 entre la languette fixe 12 et la languette mobile 13 en position droite, et que la trappe d'accès 14 coopère avec ledit organe de liaison 15, est en position fermée et est fixée sur la planche avant 5 dudit coffre 1.The trunk 1 according to the invention is as shown in figure 2 , that is to say that the connecting member 15 is fixed on the front longitudinal edge 11 of the fixed portion 8 of the lower board 6 between the fixed tongue 12 and the movable tongue 13 in the straight position, and that the access hatch 14 cooperates with said connecting member 15, is in the closed position and is fixed on the front board 5 of said trunk 1.

En référence à la figure 4, on retire les organes de fixation pour libérer la trappe d'accès 14 et la faire pivoter par rapport à l'axe de pivotement 17 selon une direction opposée audit coffre 1.In reference to the figure 4 , the fixing members are removed to release the access hatch 14 and make it pivot relative to the pivot axis 17 in a direction opposite to said box 1.

En référence à la figure 5, après désolidarisé la trappe d'accès 14 de l'organe de liaison 15, on retire les moyens de fixation 22 pour libérer et retirer ledit organe de liaison 15 du coffre 1.In reference to the Figure 5 , after detaching the access hatch 14 from the connecting member 15, the fixing means 22 are removed to release and remove said connecting member 15 from the trunk 1.

En référence à la figure 6, on fait pivoter la languette mobile 13 jusqu'à sa position inclinée de sorte à dégager toute l'ouverture 10 et permettre le retrait du bloc inférieur 27B de l'isolant 27.In reference to the Figure 6 , the movable tongue 13 is pivoted to its inclined position so as to clear the entire opening 10 and allow the lower block 27B to be removed from the insulator 27.

Enfin, en référence à la figure 7, on procède au retrait du bloc supérieur 27A de l'isolant 27 afin de dégager l'accès au volume interne 7 en vue, par exemple, d'une opération de maintenance.Finally, with reference to the Figure 7 , the upper block 27A is removed from the insulator 27 in order to provide access to the internal volume 7 with a view, for example, to a maintenance operation.

On procédera évidemment à l'inverse par remettre en place la trappe d'accès 14 et refermer le coffre 1 selon l'invention.We will obviously proceed in the opposite way by replacing the access hatch 14 and closing the trunk 1 according to the invention.

On comprend bien que par la mise en oeuvre d'organe de liaison 15 amovible et d'une languette mobile 13, le coffre 1 selon l'invention permet d'obtenir une largeur de l'ouverture 10 maximale et donc un accès aisé à l'intérieur dudit coffre 1.It is clearly understood that by the use of a removable connecting member 15 and a movable tongue 13, the box 1 according to the invention makes it possible to obtain a maximum width of the opening 10 and therefore easy access to the inside said trunk 1.

Le coffre 1 selon l'invention trouve une application particulière pour contenir un volet roulant d'une fenêtre ou d'une porte.The box 1 according to the invention finds a particular application for containing a rolling shutter of a window or a door.

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