Description

L'invention a trait à un dispositif d'immobilisation d'une plaque de fermeture par rapport à au moins une joue d'extrémité d'un coffre tunnel appartenant à une installation de fermeture ou de protection solaire. L'invention a également trait à une installation de fermeture ou de protection solaire comprenant, entre autres, un tel dispositif d'immobilisation.The invention relates to a device for immobilizing a closure plate with respect to at least one end cheek of a tunnel trunk belonging to a closure or sun protection system. The invention also relates to a closure or sun protection system comprising, inter alia, such an immobilizer.

Dans le domaine des installations de fermeture ou de protection solaire, il est connu de loger un arbre d'enroulement d'un tablier, qui peut être souple ou à lamelles, à l'intérieur d'un coffre dit « coffre tunnel » qui est disposé en linteau d'une ouverture obturée sélectivement au moyen du tablier. Dans une telle installation, le tablier peut constituer un volet roulant ou un store.In the field of closure or sun protection systems, it is known to house a winding shaft of an apron, which may be flexible or slats, inside a trunk called "tunnel chest" which is arranged in the lintel of an opening closed selectively by means of the apron. In such an installation, the deck may be a roller shutter or a blind.

Des joues sont montées aux extrémités du coffre tunnel pour supporter l'arbre d'enroulement, avec possibilité de rotation autour de son axe longitudinal. Ces joues comportent généralement un talon qui permet de poser le coffre tunnel sur un mur en cours de construction et de créer une réservation latérale permettant de recevoir un organe d'entraînement de l'arbre d'enroulement, de type poulie, moteur ou treuil. Les coffres tunnel doivent permettre un accès par le dessous, afin d'être compatibles avec l'installation de l'arbre d'enroulement équipé du tablier entre les joues et d'autoriser des interventions de maintenance sur l'installation. Les coffres tunnel sont donc pourvus d'une ouverture longitudinale allongée, de largeur relativement importante. Afin d'éviter que le mécanisme d'enroulement du tablier soit accessible et visible pour une personne se tenant à proximité de l'ouverture, et en dessous du coffre tunnel, il est connu de rapporter une plaque de fermeture sous le coffre tunnel, en ménageant une fente de passage du tablier.Cheeks are mounted at the ends of the tunnel box to support the winding shaft, with the possibility of rotation about its longitudinal axis. These cheeks generally comprise a heel which allows to put the tunnel box on a wall under construction and to create a lateral reservation for receiving a drive member of the winding shaft, pulley type, motor or winch. Tunnel boxes must allow access from below, in order to be compatible with the installation of the winding shaft equipped with the deck between the cheeks and to allow maintenance interventions on the installation. Tunnel boxes are therefore provided with an elongated longitudinal opening, of relatively large width. In order to prevent the winding mechanism of the apron from being accessible and visible for a person standing near the opening, and below the tunnel box, it is known to bring a closure plate under the tunnel box, providing a slit passage of the apron.

FR-A-2 931 512 enseigne d'utiliser, pour solidariser une surface de fermeture avec le talon d'une joue, un organe de manoeuvre accessible depuis l'extérieur, après assemblage du coffre tunnel. Ceci est peu esthétique et constitue une indication pour une personne malintentionnée qui désire démonter cette surface et accéder au mécanisme d'entraînement de l'arbre d'enroulement, notamment en vue de le manoeuvrer pour enrouler le tablier sur son arbre, sans y être autorisé. FR-A-2 931 512 teaches to use, for securing a closure surface with the heel of a cheek, an actuator accessible from the outside, after assembly of the tunnel box. This is unattractive and is an indication for a malicious person who desires to disassemble this surface and access the drive mechanism of the winding shaft, especially for the purpose of the maneuver to wind the deck on his shaft, without being allowed .

Il est également connu de FR-A-2 880 909 ou de FR-A-2 835 876 d'avoir recours à des targettes mobiles en translation pour bloquer une plaque de fermeture par rapport à une joue d'extrémité d'un coffre tunnel. L'utilisation de telles targettes requiert de configurer spécialement la plaque de fermeture, ce qui augmente son prix de revient. En outre, ces targettes sont d'un accès relativement facile et visibles depuis l'extérieur. Ceci permet à une personne malintentionnée de les repérer facilement, pour démonter la plaque de fermeture et accéder au mécanisme d'enroulement du tablier, comme dans le cas précédent.It is also known to FR-A-2,880,909 or FR-A-2,835,876 to use movable spikes in translation to block a closure plate with respect to an end cheek of a tunnel trunk. The use of such targets requires specially configure the closing plate, which increases its cost price. In addition, these targets are relatively easy to access and visible from the outside. This allows a malicious person to locate easily, to remove the closure plate and access the winding mechanism of the deck, as in the previous case.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau dispositif d'immobilisation d'une plaque de fermeture qui est aisé à mettre en oeuvre, discret une fois installé et qui ne requiert pas de personnalisation spécifique de la plaque de fermeture.It is these disadvantages that the invention intends to remedy more particularly by proposing a new device for immobilizing a closure plate which is easy to implement, discrete once installed and which does not require specific customization of the closing plate.

A cet effet, l'invention concerne un dispositif d'immobilisation d'une plaque de fermeture par rapport à au moins une joue d'extrémité d'un caisson appartenant à une installation de fermeture ou de protection solaire. Conformément à l'invention, ce dispositif d'immobilisation comprend au moins un pion apte à être monté sur la plaque de fermeture, au voisinage d'une paroi supérieure de cette plaque, ainsi qu'un loquet qui est, en totalité ou en partie, monté mobile en rotation par rapport à la plaque de fermeture entre une première position où, lorsque le pion est monté sur la plaque de fermeture, le loquet ne peut pas interagir avec la joue et ne s'oppose pas au retrait de la plaque de fermeture par rapport au coffre tunnel, et une deuxième position où, lorsque le pion est monté sur la plaque de fermeture en place par rapport au coffre tunnel, le loquet est apte à interagir avec la joue pour verrouiller la plaque de fermeture par rapport à cette joue.For this purpose, the invention relates to a device for immobilizing a closure plate relative to at least one end flange of a box belonging to a closure or sun protection system. According to the invention, this immobilizing device comprises at least one pin adapted to be mounted on the closure plate, in the vicinity of an upper wall of this plate, as well as a latch which is, in whole or in part , rotatably mounted relative to the closure plate between a first position where, when the pin is mounted on the closure plate, the latch can not interact with the cheek and does not oppose the removal of the plate from closing relative to the tunnel box, and a second position where, when the pin is mounted on the closure plate in place relative to the tunnel box, the latch is able to interact with the cheek to lock the closure plate relative to this play.

Grâce à l'invention, une fois la plaque de fermeture en place et verrouillée, son dispositif d'immobilisation n'est pas visible ou est peu visible, au point qu'une personne malintentionnée ne détecte pas qu'elle pourrait accéder au dispositif d'immobilisation pour le manoeuvrer dans un sens de libération de la plaque de fermeture.Thanks to the invention, once the closure plate is in place and locked, its immobilizing device is not visible or is not very visible, to the point that a malicious person does not detect that it could access the device. immobilization to maneuver in a direction of release of the closure plate.

L'installation 1 représentée sur les figures 1 à 9 comprend un caisson C qui comprend un coffre tunnel 2 destiné à être installé en linteau d'une ouverture à obturer sélectivement au moyen d'un tablier 3 formé de lattes formant un volet. Sur les figures, le coffre tunnel 2 est monobloc avec une section en U renversé. Selon une variante, il peut être réalisé par l'assemblage de deux demi-coffres en forme de L inversé.The installation 1 represented on the Figures 1 to 9 comprises a box C which comprises a tunnel box 2 intended to be installed in lintel of an opening to be closed selectively by means of an apron 3 formed of slats forming a shutter. In the figures, the tunnel trunk 2 is monobloc with an inverted U-shaped section. According to a variant, it can be achieved by assembling two half-boxes L-shaped inverted.

Le caisson C de l'installation 1 comprend également un tube d'enroulement 4 auquel le tablier 3 est relié par deux sangles 5. Un moteur électrique tubulaire 6 est engagé dans le tube d'enroulement 4 et permet d'entraîner celui-ci en rotation, autour d'un axe X4 longitudinal pour le tube d'enroulement 4 et horizontal en configuration installée du tube dans le coffre tunnel 2. En variante, les sangles 5 peuvent être remplacées par des dispositifs de liaison mécaniques semi-rigides à arc-boutement, dits « verrous automatiques ».The caisson C of the installation 1 also comprises a winding tube 4 to which the apron 3 is connected by two straps 5. A tubular electric motor 6 is engaged in the winding tube 4 and serves to drive it rotation, about a longitudinal axis X4 for the winding tube 4 and horizontal installed configuration of the tube in the trunk tunnel 2. Alternatively, the straps 5 can be replaced by semi-rigid mechanical connection devices to arc stubborn, so-called "automatic locks".

Deux joues 7 et 8 sont respectivement montées aux extrémités du coffre tunnel 2. La joue 7 comprend une plaque 71 et un talon 72, alors que la joue 8 comprend une plaque 81 et un talon 82. Les éléments 71 et 72 sont assemblés par coopération de formes, de même que les éléments 81 et 82. En variante, les joues d'extrémités 7 et 8 peuvent être monobloc.Two cheeks 7 and 8 are respectively mounted at the ends of the tunnel trunk 2. The cheek 7 comprises a plate 71 and a heel 72, while the cheek 8 comprises a plate 81 and a heel 82. The elements 71 and 72 are assembled by cooperation As a variant, the end cheeks 7 and 8 may be one-piece.

La plaque 71 définit une zone 73 de réception d'une partie du moteur 6 qui forme un palier de soutien de l'arbre 4. De la même façon, une zone comparable est prévue dans la joue 8, dans la partie de la plaque 81 masquée à la figure 1.The plate 71 defines a zone 73 for receiving a part of the motor 6 which forms a support bearing for the shaft 4. In the same way, a comparable zone is provided in the cheek 8, in the part of the plate 81 hidden at the figure 1 .

Divers organes non représentés sont prévus pour, d'une part, former des paliers entre l'arbre 4 et les joues 7 et 8 et, d'autre part, guider la partie déployée du tablier 3 dans son mouvement vertical.Various non-represented members are provided for, on the one hand, forming bearings between the shaft 4 and the cheeks 7 and 8 and, on the other hand, guide the deployed part of the deck 3 in its vertical movement.

On note 22 l'ouverture inférieure du coffre tunnel 2 qui est aussi une ouverture inférieure du caisson C. Cette ouverture est obturée par une plaque de fermeture 9 qui est réalisée par extrusion de matière plastique et comprend une paroi supérieure 91, une paroi inférieure 92 et des nervures 93 qui s'étendent verticalement entre les parois 91 et 92. On note X9 un axe longitudinal de la plaque 9. Cet axe est parallèle à l'axe X4 en configuration montée de la plaque 9 par rapport au reste de l'installation. Les nervures 93 sont parallèles à l'axe X9 et définissent entre elles des canaux 94 parallèles à cet axe et de section rectangulaire. En configuration montée de la plaque 9 par rapport au reste de l'installation 1, cette plaque obture l'ouverture 22 sur l'essentiel de sa largeur, entre les bords inférieurs 23 et 24 du coffre 2. Dans cette position, la plaque 9 laisse subsister une fente 25 qui permet le passage du tablier 3 lors d'abaissement ou de relevage.We note 22 the lower opening of the tunnel box 2 which is also a lower opening of the box C. This opening is closed by a closure plate 9 which is made by extrusion of plastic material and comprises an upper wall 91, a lower wall 92 and ribs 93 which extend vertically between the walls 91 and 92. X9 is a longitudinal axis of the plate 9. This axis is parallel to the axis X4 in the mounted configuration of the plate 9 relative to the rest of the installation. The ribs 93 are parallel to the axis X9 and define between them channels 94 parallel to this axis and of rectangular section. In mounted configuration of the plate 9 relative to the rest of the installation 1, this plate closes the opening 22 over most of its width, between the lower edges 23 and 24 of the box 2. In this position, the plate 9 leave a slot 25 which allows the passage of the deck 3 during lowering or lifting.

On note 95 le bord longitudinal de la plaque 9 qui délimite la fente 25 avec le bord adjacent 24 du coffre 2. Ce bord 95 est équipé d'une nervure 96 qui participe à la rigidification de la plaque 9 et peut constituer en cas de flexion des tabliers de grandes largeurs, un moyen de guidage complémentaire de la partie du tablier 3 qui s'étend entre la portion de ce tablier enroulée sur l'arbre 4 et la fente 25.We note 95 the longitudinal edge of the plate 9 which defines the slot 25 with the adjacent edge 24 of the box 2. This edge 95 is equipped with a rib 96 which contributes to the stiffening of the plate 9 and may constitute in case of flexion aprons of large widths, a guiding means complementary to the part of the apron 3 which extends between the portion of this apron wound on the shaft 4 and the slot 25.

Pour remplir efficacement sa fonction d'obturation partielle de l'ouverture 22, la plaque 9 doit être immobilisée par rapport aux joues 7 et 8.To effectively fulfill its function of partially closing off the opening 22, the plate 9 must be immobilized with respect to the cheeks 7 and 8.

Pour ce faire, une clé rotative 100 est montée sur chacun des bords transversaux 97 et 98 de la plaque de fermeture 9. Les bords transversaux 97 et 98 sont perpendiculaires à l'axe X9 et au bord 95.To do this, a rotary key 100 is mounted on each of the transverse edges 97 and 98 of the closure plate 9. The transverse edges 97 and 98 are perpendicular to the axis X9 and the edge 95.

Les clés rotatives 100 sont identiques et l'une d'entre elles est représentée en éclaté à la figure 2. Chaque clé rotative 100 est constituée d'une embase 110 et d'un loquet 120. Chacune des pièces 110 et 120 est monobloc et réalisée par moulage de matière plastique, par exemple de Polyamide.The rotary keys 100 are identical and one of them is shown exploded at the figure 2 . Each rotary key 100 consists of a base 110 and a latch 120. Each of the parts 110 and 120 is monobloc and made by molding plastic material, for example polyamide.

L'embase 110 comprend un support 111 conçu pour s'accrocher sur un bord transversal 97, 98 de la plaque 9, ainsi qu'un pion 112 qui s'étend en saillie par rapport à une surface supérieure 113 du support 111.The base 110 comprises a support 111 designed to hang on a transverse edge 97, 98 of the plate 9, and a pin 112 which protrudes from an upper surface 113 of the support 111.

Dans la présente description, les notions de « haut », « bas », « supérieur » et « inférieur » s'entendent par rapport à une configuration montée de l'installation 1. Dans cette configuration, une partie « supérieure » d'une pièce est orientée vers le haut, alors qu'une partie « inférieure » est orientée vers le bas, et une partie « supérieure » est située au dessus d'une partie « inférieure ».In the present description, the notions of "up", "down", "upper" and "lower" mean with respect to a mounted configuration of the installation 1. In this configuration, a "superior" part of a The coin is facing up, while a "lower" part is facing down, and a "higher" part is located above a "lower" part.

Le pion 112 s'étend selon un axe Z112 perpendiculaire à la surface 113 et vertical en configuration d'utilisation de la clé rotative 100. Le pion 112 est constitué de deux languettes 112A et 112B qui définissent entre elles un espace 112C permettant le débattement des languettes 112A et 112B l'une vers l'autre lors de la mise en place du loquet 120 sur le pion 112.The pin 112 extends along an axis Z112 perpendicular to the surface 113 and vertical in the configuration of use of the rotary key 100. The pin 112 consists of two tabs 112A and 112B which define between them a space 112C allowing the clearance of tongues 112A and 112B towards each other during the introduction of the latch 120 on the pin 112.

Les extrémités supérieures des languettes 112A et 112B, c'est-à-dire leurs extrémités opposées à la surface 113 sont pourvues chacune d'une surface 112D en portion de tronc de cône destinée à faciliter la transmission d'effort entre le loquet 120 et les languettes 112A et 112B lors de la mise en place du loquet. Ces extrémités sont également chacune pourvue d'un épaulement 112E de retenue en position du loquet 120 sur le pion 112. Le pion 112 est cylindrique et à section externe circulaire entre la surface 112 et les épaulements 112E.The upper ends of the tongues 112A and 112B, that is to say their ends opposite to the surface 113 are each provided with a surface 112D in truncated cone portion intended to facilitate the transmission of force between the latch 120 and the tongues 112A and 112B during the installation of the latch. These ends are also each provided with a shoulder 112E retaining the latch 120 on the pin 112. The pin 112 is cylindrical and circular outer section between the surface 112 and the shoulders 112E.

Le support 111 comprend trois dents 114A, 114B et 114C qui sont séparés deux à deux par des fentes 114E et 114F.The support 111 comprises three teeth 114A, 114B and 114C which are separated in pairs by slots 114E and 114F.

Le support 111 comprend une plaque 115 dont la surface 113 constitue la face supérieure et dont la face inférieure 116 est tournée vers les dents 114A à 114C. On note e1 l'épaisseur de la plaque 115, c'est-à-dire la distance, mesurée parallèlement à l'axe Z112, entre les faces 113 et 116. Entre la surface 116 et les dents 114A à 114C, le support 111 définit une fente 117 de réception de la paroi supérieure 91 de la plaque 9 en configuration montée de la clé rotative 100 sur la plaque 9. Les dimensions transversales des dents 114A à 114C, c'est-à-dire leurs largeurs et hauteurs respectives, mesurées à leur plus grande dimension, sont compatibles avec l'introduction de ces dents dans les canaux 94, avec un faible jeu. Ainsi, les dents 114 constituent des organes de blocage aptes à pénétrer dans les canaux 94, avec réception des nervures 93 dans les fentes 114E et 114F.The support 111 comprises a plate 115 whose surface 113 constitutes the upper face and whose lower face 116 is turned towards the teeth 114A to 114C. Note e1 the thickness of the plate 115, that is to say the distance, measured parallel to the axis Z112, between the faces 113 and 116. Between the surface 116 and the teeth 114A to 114C, the support 111 defines a slot 117 for receiving the upper wall 91 of the plate 9 in the mounted configuration of the rotary key 100 on the plate 9. The transverse dimensions of the teeth 114A to 114C, that is to say their respective widths and heights, measured at their largest dimension, are compatible with the introduction of these teeth into the channels 94, with a small clearance. Thus, the teeth 114 constitute locking members capable of penetrating the channels 94, with the reception of the ribs 93 in slots 114E and 114F.

On remarque que la surface supérieure des dents 114A, 114B et 114C est inclinée en direction de la surface 116, en s'éloignant de l'extrémité libre de ces dents puis parallèle à cette surface au niveau de la fente 117. Le caractère incliné de la surface supérieure des dents 114A, 114B et 114C facilite la mise en place de l'embase 110 sur la plaque 9.Note that the upper surface of the teeth 114A, 114B and 114C is inclined towards the surface 116, away from the free end of these teeth and then parallel to this surface at the slit 117. The inclined character of the upper surface of the teeth 114A, 114B and 114C facilitates the introduction of the base 110 on the plate 9.

Compte tenu de la géométrie de l'embase 110, chaque clé de verrouillage 100 peut être montée sur la plaque de fermeture 9 sans modification de cette plaque de fermeture par rapport à sa configuration à l'issue de sa mise à la longueur, en fonction de la longueur du coffre tunnel 2 le long de l'axe X4. Ainsi, il n'est pas nécessaire de « personnaliser » ou « spécifier » la plaque de fermeture 9 pour qu'elle puisse coopérer avec les clés rotatives 100.Given the geometry of the base 110, each locking key 100 can be mounted on the closure plate 9 without modification of the closure plate with respect to its configuration after its setting to length, according to the length of the tunnel vault 2 along the axis X4. Thus, it is not necessary to "customize" or "specify" the closure plate 9 so that it can cooperate with the rotary keys 100.

Le loquet 120 comprend un fût 121 dans lequel est définie une ouverture cylindrique à section circulaire 122 de diamètre légèrement supérieur au diamètre extérieur des parties du pion 112 situé entre la surface 113 et les épaulements 112E. Ainsi, le loquet 120 peut tourner autour de l'axe Z112 lorsqu'il est monté sur l'embase 110. Le loquet 120 comprend également un pêne 123 qui s'étend selon une direction de projection Y123 perpendiculaire à l'axe Z112 lorsque le loquet 120 est monté sur l'embase 110. Une nervure de renforcement 124 s'étend entre le pêne 123 et le fut 121.The latch 120 comprises a shank 121 in which is defined a cylindrical opening with a circular section 122 of diameter slightly greater than the outside diameter of the parts of the pin 112 situated between the surface 113 and the shoulders 112E. Thus, the latch 120 can rotate around the axis Z112 when it is mounted on the base 110. The latch 120 also comprises a bolt 123 which extends in a projection direction Y123 perpendicular to the axis Z112 when the latch 120 is mounted on the base 110. A reinforcing rib 124 extends between the bolt 123 and it was 121.

En variante, la direction Y123 peut ne pas être rigoureusement perpendiculaire à l'axe Z112, mais sensiblement perpendiculaire à celui-ci, par exemple en formant avec cet axe un angle compris entre 80° et 100°. De façon générale, la direction Y123 est radiale par rapport à l'axe Z112.Alternatively, the direction Y123 may not be strictly perpendicular to the axis Z112, but substantially perpendicular to it, for example by forming with this axis an angle of between 80 ° and 100 °. In general, the Y123 direction is radial with respect to the Z112 axis.

Une poignée 125 comprend deux branches 125A et 125B qui s'étendent radialement par rapport au fût 121, ainsi qu'un arc 125C qui relie les extrémités des branches 125A et 125B.A handle 125 comprises two branches 125A and 125B which extend radially relative to the shaft 121, and an arc 125C which connects the ends of the branches 125A and 125B.

On note 121A la surface du fut 121 qui vient en appui contre la surface 113 en configuration montée du loquet 120 sur l'embase 110. On note Z122 l'axe central de l'ouverture 122.121A is noted on the surface of the cartridge 121 which abuts against the surface 113 in mounted configuration of the latch 120 on the base 110. Z122 is noted as the central axis of the opening 122.

On note 125D la surface inférieure de l'arc 125C, c'est-à-dire la surface de cet arc tournée vers le support 111 en configuration montée du loquet 120 sur l'embase 110. On note d1 la distance, mesurée parallèlement à l'axe Z122, entre les surfaces 121A et 125D.125D is the lower surface of the arc 125C, that is to say the surface of this arc turned towards the support 111 in the mounted configuration of the latch 120 on the base 110. Note d1 the distance, measured parallel to the axis Z122, between the surfaces 121A and 125D.

En configuration montée du loquet 120 sur l'embase 110, la distance d1 est la distance, mesurée parallèlement à l'axe Z112, entre les surfaces 113 et 125D.In mounted configuration of the latch 120 on the base 110, the distance d1 is the distance, measured parallel to the axis Z112, between the surfaces 113 and 125D.

Le talon 72 laisse subsister, par rapport à un voile inférieur 722 du talon 72, un espace 75 dans lequel peut être engagée l'extrémité libre 123A du pêne 123. En partie supérieure, le logement 75 est bordé par un voile 724, monobloc avec le reste du talon 72 et dont le bord 725 s'étend en retrait, le long de l'axe X4, par rapport au bord 723 du voile inférieur 722.The heel 72 leaves, in relation to a lower web 722 of the heel 72, a space 75 in which the free end 123A of the bolt 123 can be engaged. In the upper part, the housing 75 is bordered by a web 724, integral with the remainder of the heel 72 and 725 whose edge extends recessed along the axis X4, relative to the edge 723 of the lower web 722.

Le montage de la plaque de fermeture 9 par rapport aux joues 7 et 8 a lieu de la façon suivante :

  • Dans une étape préalable de fabrication des deux clés rotatives 100, un loquet 120 est monté sur chaque embase 110 en introduisant le pion 112 de cette embase dans l'ouverture 122 du loquet.
The mounting of the closure plate 9 with respect to the cheeks 7 and 8 takes place as follows:
  • In a prior step of manufacturing the two rotary wrenches 100, a latch 120 is mounted on each base 110 by introducing the pin 112 of this base into the opening 122 of the latch.

Lorsque la plaque 9 a été mise à la longueur du coffre tunnel 2, c'est-à-dire recoupée pour pouvoir être engagée entre les talons 72 et 82 des joues 7 et 8 à faible jeu, on introduit les dents 114A à 114C d'une embase 110 équipée de son loquet dans les canaux 94 de la plaque de fermeture 9, au niveau du bord transversal 97 de cette plaque et au voisinage de la nervure 96. De part cette introduction, la paroi supérieure 91 de la plaque 9 est engagée dans la fente 117 de cette embase 110. La largeur de la fente 117, c'est-à-dire sa hauteur h1 entre la face 116 et la face supérieure des dents 116A à 114C, est choisie, par rapport à l'épaisseur e9 de la paroi 91, pour que cette introduction résulte en un coincement de la paroi 91 dans la fente 117 et, par conséquent, en un blocage de l'embase 110 sur le bord transversal 97. En particulier, la hauteur h1 peut être choisie légèrement inférieure, par exemple de 5%, à l'épaisseur e9.When the plate 9 has been put to the length of the tunnel trunk 2, that is to say cut to be engaged between the heels 72 and 82 of the cheeks 7 and 8 at low play, are introduced the teeth 114A to 114C d a base 110 equipped with its latch in the channels 94 of the closing plate 9, at the transverse edge 97 of this plate and in the vicinity of the rib 96. By this introduction, the upper wall 91 of the plate 9 is engaged in the slot 117 of this base 110. The width of the slot 117, that is to say its height h1 between the face 116 and the upper face of the teeth 116A to 114C, is chosen, with respect to the thickness e9 of the wall 91, so that this introduction results in a wedging of the wall 91 in the slot 117 and, therefore, a blocking of the base 110 on the transverse edge 97. In particular, the height h1 may be chosen slightly lower, for example by 5%, the thickness e9.

De la même façon, on monte la deuxième clé de verrouillage 100 sur le bord 98 en engageant les dents 114A à 114C de son embase dans les conduits 94, entre le milieu de ce bord et la nervure 96.In the same way, the second locking key 100 is mounted on the edge 98 by engaging the teeth 114A to 114C of its base in the ducts 94, between the middle of this edge and the rib 96.

En variante, les embases 110 peuvent être mises en place sur les bords 97 et 98 avant montage des loquets 120 sur ces embases.Alternatively, the bases 110 may be placed on the edges 97 and 98 before mounting latches 120 on these bases.

Lorsque les clés de verrouillage 100 sont en place sur les bords 97 et 98, on peut agir sur chaque loquet 120, en le faisant tourner autour de l'axe de rotation Z112 défini par le pion 112, pour l'amener dans une première position où le pêne 123 ne dépasse pas, par rapport à la plaque 9, au-delà de son bord transversal 97 ou 98, alors que la poignée 125 ne dépasse pas non plus au-delà de ce bord. En variante, dans cette première position, le pêne 123 dépasse du bord 97 ou 98 sur une distance qui est inférieure à la distance entre les bords 723 et 725.When the locking keys 100 are in place on the edges 97 and 98, it is possible to act on each latch 120, by rotating it around the axis of rotation Z112 defined by the pin 112, to bring it into a first position. where the bolt 123 does not exceed, relative to the plate 9, beyond its transverse edge 97 or 98, while the handle 125 does not exceed beyond this edge. Alternatively, in this first position, the bolt 123 protrudes from the edge 97 or 98 by a distance that is less than the distance between the edges 723 and 725.

En d'autres termes, dans cette première position, le loquet 120 est orienté pour ne pas gêner la mise en place de la plaque de fermeture 9 dans l'ouverture 22, par le dessous. Lors du réglage de la position angulaire du loquet 120 par rapport à l'axe Z112, on veille à orienter la poignée 125 du côté de la nervure 96 de la plaque 9. Lorsque la plaque 9 est en place dans l'ouverture 22, on pousse cette plaque en direction du bord 23 du coffre tunnel 2 afin d'engager le bord longitudinal 99 de la plaque 9 opposé au bord 95 dans une gorge longitudinale 26 ménagée le long du bord 23. Ce mouvement est représenté par la flèche F1 à la figure 3.In other words, in this first position, the latch 120 is oriented so as not to hinder the establishment of the closure plate 9 in the opening 22, from below. When adjusting the angular position of the latch 120 with respect to the axis Z112, care is taken to orient the handle 125 on the side of the rib 96 of the plate 9. When the plate 9 is in place in the opening 22, pushes this plate towards the edge 23 of the tunnel box 2 to engage the longitudinal edge 99 of the plate 9 opposite the edge 95 in a longitudinal groove 26 formed along the edge 23. This movement is represented by the arrow F1 to the figure 3 .

A partir de cette position, il est possible de faire tourner le loquet 120 autour de l'axe Z112, dans le sens de la flèche de rotation R1 aux figures 4 et 6, ce qui a pour effet d'amener progressivement l'extrémité libre 123A du pêne 123 à se projeter selon la direction Y123 au-delà du bord 97 ou 98, en parvenant au dessus du voile inférieur 722 du talon 72, puis dans l'espace 75, ce qui est représenté par le passage de la position intermédiaire des figures 4, 6 et 8 à la position finale des figures 5, 7 et 9.From this position, it is possible to rotate the latch 120 about the axis Z112, in the direction of the rotation arrow R1 to figures 4 and 6 , which has the effect of progressively bringing the free end 123A of the bolt 123 to project in the Y123 direction beyond the edge 97 or 98, reaching above the lower web 722 of the heel 72, then in the space 75, which is represented by the passage of the intermediate position of figures 4 , 6 and 8 at the final position of figures 5 , 7 and 9 .

Dans la deuxième position des figures 5, 7 et 9, le pêne 123 est en appui sur le voile 722 du talon 72 qui est lui-même en appui sur le mur du bâtiment dans lequel est percée l'ouverture à obturer avec le tablier 3. Le voile 72 constitue donc une butée à un mouvement dirigé vers le bas de la clé de verrou 100 et, par la même, de la plaque de fermeture 9 avec laquelle cette clé est solidaire.In the second position of figures 5 , 7 and 9 , the bolt 123 is supported on the web 722 of the heel 72 which is itself supported on the wall of the building in which is pierced the opening to be closed with the apron 3. The sail 72 is therefore a stop to a movement directed down the lock key 100 and, by the same, the closure plate 9 with which this key is secured.

On comprend que la manipulation mentionné ci-dessus est réalisée au niveau de chaque bord transversal 97 ou 98 de la plaque 9 pour l'immobiliser par rapport au talon 72 ou 82 de la joue 7 ou 8 adjacente.It is understood that the manipulation mentioned above is carried out at each transverse edge 97 or 98 of the plate 9 to immobilize it with respect to the heel 72 or 82 of the cheek 7 or 8 adjacent.

On note h9 la hauteur de la nervure 96 par rapport à la surface supérieure 91 de la plaque 9. La hauteur h9 est mesurée perpendiculairement à la paroi 91 qui est plane.Note h9 the height of the rib 96 relative to the upper surface 91 of the plate 9. The height h9 is measured perpendicular to the wall 91 which is flat.

Par construction, la distance d1 est choisie de telle sorte que sa somme avec l'épaisseur e1 est supérieure à la hauteur h9, ce qui permet que la poignée 125 peut passer au dessus de la nervure 96 dans la configuration escamotée du loquet 120 dans laquelle ce loquet est dans sa première position identifiée ci-dessus. Ainsi, il est possible d'insérer les dents 114A à 114C du support 111 dans des canaux 94 de la plaque de fermeture 9 suffisamment proches de la nervure 96 pour que la poignée 125 soit accessible à travers la fente 25, en glissant les doigts au dessus de la nervure 96.By construction, the distance d1 is chosen such that its sum with the thickness e1 is greater than the height h9, which allows the handle 125 to pass over the rib 96 in the retracted configuration of the latch 120 in which this latch is in its first position identified above. Thus, it is possible to insert the teeth 114A to 114C of the support 111 in the channels 94 of the closure plate 9 sufficiently close to the rib 96 so that the handle 125 is accessible through the slot 25, by sliding the fingers to above the rib 96.

Une fois la plaque de fermeture immobilisée par rapport aux joues 7 et 8 grâce aux clés rotatives 100, il n'est pas possible, à partir du dessous de la plaque 9, de repérer ces dispositifs de blocage 100 puisqu'aucune partie de ces dispositifs ne traverse la paroi 92 ou n'est visible à travers la fente 25. En effet, dans la configuration des figures 5, 7 et 9, la poignée 25 ne dépasse pas au-delà du bord 95, au dessus de la nervure 96.Once the closure plate immobilized with respect to the cheeks 7 and 8 by means of the rotary wrenches 100, it is not possible, from the underside of the plate 9, to identify these blocking devices 100 since no part of these devices does not cross the wall 92 or is visible through the slot 25. Indeed, in the configuration of the figures 5 , 7 and 9 the handle 25 does not protrude beyond the edge 95, above the rib 96.

En pratique, en tenant compte que la hauteur h9 d'une nervure 96 est de l'ordre de 20 mm, les valeurs de e1 et d1 sont respectivement choisies entre 2 et 4 et entre 17 et 20 mm et leur somme est supérieure ou égale à 21 mm.In practice, taking into account that the height h9 of a rib 96 is of the order of 20 mm, the values of e1 and d1 are respectively chosen between 2 and 4 and between 17 and 20 mm and their sum is greater than or equal to at 21 mm.

Le rapport des grandeurs d1, e1 et h9 est particulièrement intéressant dans le cas où la plaque 9 est montée avec sa nervure 96 s'étendant vers le haut. Il est toutefois possible de monter la plaque 9 avec sa nervure 96 s'étendant vers le bas. Il suffit pour cela d'engager les dents 114A à 114C de l'embase 110 dans les canaux 94 de la plaque 9 avec le pion 112 tourné à l'opposé de la nervure 96. En d'autres termes, l'invention permet de monter la plaque 9 dans deux configurations distinctes, sans modification structurelle.The ratio of the quantities d1, e1 and h9 is particularly interesting in the case where the plate 9 is mounted with its rib 96 extending upwards. It is however possible to mount the plate 9 with its rib 96 extending downwards. To do this, it suffices to engage the teeth 114A to 114C of the base 110 in the channels 94 of the plate 9 with the pin 112 turned away from the rib 96. In other words, the invention makes it possible to mount the plate 9 in two separate configurations, without structural modification.

L'invention peut également être utilisée avec une plaque de fermeture dépourvue de nervure longitudinale le long de son bord qui définit la fente de passage du tablier.The invention can also be used with a closure plate without a longitudinal rib along its edge which defines the passage slot of the apron.

Lorsqu'il convient de retirer la plaque de fermeture 9 pour une opération de maintenance, il suffit à l'opérateur de glisser les doigts dans la fente 25, par le dessous, puis de manoeuvrer la poignée 125 du loquet 120 pour le ramener dans sa première position, ce qui permet de retirer la plaque de fermeture 9 sous l'effet de la gravité.When it is necessary to remove the closure plate 9 for a maintenance operation, it is sufficient for the operator to slide the fingers into the slot 25, from below, then to operate the handle 125 of the latch 120 to bring it back into its slot. first position, which allows to remove the closure plate 9 under the effect of gravity.

Selon une caractéristique optionnelle de l'invention qui n'est pas représentée, une clé rotative 100 est équipée d'un ressort, par exemple un ressort spirale, logé entre l'embase 110 et le loquet 120, ce ressort ayant pour effet d'exercer un couple élastique qui tend à ramener par défaut le loquet 120 en configuration de verrouillage, c'est-à-dire dans la configuration des figures 5, 7 et 9.According to an optional feature of the invention which is not shown, a rotary key 100 is equipped with a spring, for example a spiral spring, housed between the base 110 and the latch 120, this spring having the effect of exert an elastic torque which tends to reduce by default the latch 120 in locking configuration, that is to say in the configuration of figures 5 , 7 and 9 .

Dans le deuxième mode de réalisation de l'invention représenté aux figures 10 à 13, les éléments analogues à ceux du premier mode de réalisation portent les mêmes références. Dans ce qui suit, on décrit principalement ce qui différencie ce mode de réalisation du précédent.In the second embodiment of the invention shown in Figures 10 to 13 elements similar to those of the first embodiment bear the same references. In what follows, we mainly describe what differentiates this embodiment from the previous one.

La clé rotative 100 de ce mode de réalisation comprend une embase 110 dont le support 111 est pourvu de deux pattes 114G et 114H qui sont destinées à pénétrer chacune dans un canal 94 d'une plaque de fermeture 9 analogue à celle du premier mode de réalisation. Ceci permet d'immobiliser l'embase 110 sur un bord transversal 97 de la plaque 9, par blocage, comme avec les dents du premier mode de réalisation.The rotary key 100 of this embodiment comprises a base 110 whose support 111 is provided with two tabs 114G and 114H which are intended to penetrate each in a channel 94 of a closure plate 9 similar to that of the first embodiment. . This makes it possible to immobilize the base 110 on a transverse edge 97 of the plate 9, by locking, as with the teeth of the first embodiment.

Comme le montrent les figures 10 et 13, la zone d'attache des pattes 114G et 114H sur la paroi d'extrémité 111A du support 111 définit, avec la plaque 115 du support 111 à partir de laquelle s'étendent le pion 112 et le guide 118, une zone 117 de réception de la paroi supérieure 91 de la plaque 9, ce qui contribue au blocage du support 111 sur le bord transversal 97 de cette plaque.As shown by figures 10 and 13 , the zone of attachment of the tabs 114G and 114H on the end wall 111A of the support 111 defines, with the plate 115 of the support 111 from which the pin 112 and the guide 118 extend, a receiving zone 117 of the upper wall 91 of the plate 9, which contributes to the blocking of the support 111 on the transverse edge 97 of this plate.

Le pion 112 de l'embase 110 est identique à celui du premier mode de réalisation et l'on note Z112 son axe longitudinal.The pin 112 of the base 110 is identical to that of the first embodiment and Z112 is noted as its longitudinal axis.

Un guide 118 en forme de T s'étend également à partir du support 111. Les extrémités des branches du guide 118 sont pourvues de retours 118A et 118B dirigés vers le support 111.A T-shaped guide 118 also extends from the support 111. The ends of the branches of the guide 118 are provided with returns 118A and 118B directed towards the support 111.

Le verrou 120 de la clé rotative 100 est bipartite et comprend un organe 120A monté mobile en rotation autour du pion 112, d'une façon comparable au verrou 120 du premier mode de réalisation. A cet effet, l'organe 120A comprend un fût 121 qui définit une ouverture 122 de réception du pion 112, ainsi qu'un pêne 123 qui s'étend selon une direction de projection Y123 radiale par rapport à un axe central Z122 de l'ouverture 122. Ce pêne est destiné à coopérer avec une partie d'une joue, comme dans le premier mode de réalisation.The latch 120 of the rotary key 100 is bipartite and comprises a member 120A rotatably mounted around the pin 112, in a manner comparable to the latch 120 of the first embodiment. For this purpose, the member 120A comprises a shank 121 which defines an opening 122 for receiving the pin 112, as well as a bolt 123 which extends in a direction of projection Y123 radial with respect to a central axis Z122 of the 122. This bolt is intended to cooperate with a part of a cheek, as in the first embodiment.

Une fois monté sur le pion 112, l'organe 120A peut pivoter autour de l'axe Z112, sur une course angulaire limitée par la coopération d'un taquet 119, en saillie par rapport à la surface supérieure de la plaque 115 du support 111, avec deux butées 126A, 126B définies de part et d'autre d'une encoche 126C ménagée dans une collerette externe 126 du fût 121. Comme il ressort de la comparaison des figures 10 et 11, le taquet 119 peut recevoir en appui l'une ou l'autre des butées 126A et 126B, en fonction de l'orientation angulaire de l'organe 120A par rapport à l'axe Z112.Once mounted on the pin 112, the member 120A can pivot about the axis Z112, on a limited angular stroke by the cooperation of a cleat 119, projecting from the upper surface of the plate 115 of the support 111 with two stops 126A, 126B defined on either side of a notch 126C formed in an outer collar 126 121. As can be seen from the comparison of figures 10 and 11 , the cleat 119 may receive bearing one or the other of the abutments 126A and 126B, depending on the angular orientation of the member 120A with respect to the axis Z112.

Comme précédemment, on note respectivement 722 et 724 des voiles inférieur et supérieur du talon 72 entre lesquels est défini un espace 75 de réception du pêne 123. Les bords respectifs 723 et 725 des voiles 722 et 724 sont décalés le long de l'axe X4, le bord 725 étant en retrait dans le talon 72 par rapport au bord 723.As before, 722 and 724 of the lower and upper sails of the heel 72 are respectively denoted between which is defined a space 75 for receiving the bolt 123. The respective edges 723 and 725 of the sails 722 and 724 are offset along the axis X4. , the edge 725 being recessed in the heel 72 with respect to the edge 723.

Comme dans le premier mode de réalisation, le loquet 120 est mobile entre la position de la figure 11 où il fait saillie par rapport au bord 97 sur une distance inférieure au décalage axial entre les bords 723 et 725, au point qu'il n'interagit pas avec le voile 724 et ne pénètre pas dans l'espace 75 du talon 72 d'une joue adjacente, et la position des figures 12 et 13, où il dépasse du bord 97 et verrouille la plaque 9 par rapport à ce talon en s'engageant dans l'espace 75.As in the first embodiment, the latch 120 is movable between the position of the figure 11 where it protrudes from the edge 97 a distance less than the axial offset between the edges 723 and 725, to the point that it does not interact with the web 724 and does not penetrate into the space 75 of the heel 72 of an adjacent cheek, and the position of figures 12 and 13 , where it protrudes from the edge 97 and locks the plate 9 with respect to this heel by engaging in the space 75.

A la différence du premier mode de réalisation, le loquet 120 ne comprend pas une poignée monobloc avec la pièce qui inclut le pêne 123, mais une tirette 120B qui est articulée sur l'organe 120A, autour d'un axe Z120 parallèle à l'axe Z112 en configuration montée du loquet 120 sur l'embase 110.Unlike the first embodiment, the latch 120 does not include a one-piece handle with the part which includes the bolt 123, but a pull 120B which is articulated on the member 120A, about a Z120 axis parallel to the Z112 axis in mounted configuration of the latch 120 on the base 110.

Plus précisément, une patte 121 B s'étend à partir de la surface externe 121C du fût 121, selon une direction radiale par rapport à l'axe Z122. Cette patte 121B a son extrémité 121D, distale par rapport au fût 121, qui est conformée en cylindre à section circulaire centrée sur l'axe Z120.Specifically, a tab 121 B extends from the outer surface 121C of the barrel 121, in a radial direction relative to the axis Z122. This tab 121B has its end 121D, distal from the barrel 121, which is shaped circular cylinder centered on the axis Z120.

Par ailleurs, la tirette 120B est formée par une languette 127 dont une extrémité 127A est conformée pour être montée autour de l'extrémité 121D, en entourant partiellement cette extrémité, de façon à permettre son articulation autour de l'axe Z120. L'extrémité 127A s'étend sur un secteur angulaire de l'ordre de 270° autour de l'axe Z120, ce qui permet un débattement angulaire de l'extrémité 121D par rapport à l'extrémité 127A en ménageant une zone de débattement pour la patte 121 B.Furthermore, the pull tab 120B is formed by a tongue 127 whose end 127A is shaped to be mounted around the end 121D, partially surrounding this end, so as to allow its articulation about the axis Z120. The end 127A extends over an angular sector of the order of 270 ° around the axis Z120, which allows an angular displacement of the end 121D with respect to the end 127A by providing a deflection zone for the leg 121 B.

A son extrémité 127B opposée à l'extrémité 127A, la languette 127 est conformée en poignée.At its end 127B opposite the end 127A, the tongue 127 is shaped handle.

En configuration montée du loquet 120 sur l'embase 110, la languette 127 est engagée sous l'une des branches du guide 118 qui constitue ainsi un moyen de guidage de la tirette 120B en translation selon une direction perpendiculaire à l'axe Z112, non sécante avec cet axe, la direction D120 n'est pas parallèle à l'axe de rotation de l'arbre d'enroulement de l'installation de ce deuxième mode de réalisation ; elle forme toutefois un angle de faible valeur par rapport à cet axe. Cet angle est variable en fonction du déplacement de la tirette car l'axe Z120 décrit un arc de cercle pendant son déplacement. La direction D120 est parallèle à la paroi supérieure 91 de la plaque 9.In mounted configuration of the latch 120 on the base 110, the tongue 127 is engaged under one of the branches of the guide 118 which thus constitutes a means for guiding the pull tab 120B in translation in a direction perpendicular to the axis Z112, no secant with this axis, the direction D120 is not parallel to the axis of rotation of the winding shaft of the installation of this second embodiment; however, it forms an angle of low value with respect to this axis. This angle is variable depending on the moving the zipper because the Z120 axis describes an arc while moving. The direction D120 is parallel to the upper wall 91 of the plate 9.

Ainsi, lorsqu'il convient de manoeuvrer la clé rotative 110, il est possible de passer la main à travers la fente 25 et d'exercer, sur la poignée d'extrémité 127B de la languette 127 et selon la direction D120, un effort de traction T, ce qui a pour effet de faire passer le loquet 120 de la configuration de la figure 11 à celle de la figure 12, en faisant pivoter l'organe 120A autour de l'axe Z112, dans un sens d'engagement du pêne 123 dans un espace 75 prévu à cet effet dans le talon 72 d'une joue 7, comme dans le premier mode de réalisation.Thus, when it is necessary to operate the rotary key 110, it is possible to pass the hand through the slot 25 and to exert, on the end handle 127B of the tongue 127 and in the direction D120, a force of T pulling, which has the effect of passing the latch 120 of the configuration of the figure 11 to that of the figure 12 , by pivoting the member 120A about the axis Z112, in a direction of engagement of the bolt 123 in a space 75 provided for this purpose in the heel 72 of a cheek 7, as in the first embodiment.

En d'autres termes, la structure bipartite du loquet 120 permet une manoeuvre de celui-ci par un effort de traction T parallèle à la paroi 91, le long de la nervure 96 de la plaque 9, ce qui s'avère aisé à mettre en oeuvre de façon intuitive pour un utilisateur.In other words, the bipartite structure of the latch 120 allows maneuvering thereof by a traction force T parallel to the wall 91, along the rib 96 of the plate 9, which is easy to put in an intuitive way for a user.

La tirette 120B constitue un organe de manoeuvre de l'organe pivotant 120A.The pull tab 120B constitutes an actuating member of the pivoting member 120A.

Compte tenu du fait que la tirette 120B se déplace le long de la nervure 96 de la plaque 9, cette tirette n'a pas à avoir une hauteur prédéfinie en fonction de la hauteur de cette nervure.Given that the zipper 120B moves along the rib 96 of the plate 9, this zipper does not have to have a predefined height depending on the height of this rib.

Dans sa partie courante, entre les extrémités 127A et 127B, le bord supérieur 127C de la languette 127 est pourvu d'un téton 127D en saillie vers le haut. Ce téton coopère avec l'une des branches du guide 118 pour constituer un point dur lors de la manoeuvre du loquet 120 de la configuration de la figure 11 à celle de la figure 12, sous l'effet de la traction T. Ce téton maintient d'une part la clé rotative en position "ouverte" et d'autre part, il évite au pêne 123 de revenir par simple vibration de la plaque 9 sous l'effet du vent et de ressortir de l'espace 75. Le point dur lors du passage du téton 127D sous la branche du guide 118 est détecté par l'utilisateur qui perçoit alors que le pêne 123 est dans une configuration où il coopère efficacement avec le talon 72 de la joue 7.In its current portion, between the ends 127A and 127B, the upper edge 127C of the tongue 127 is provided with a pin 127D projecting upwards. This stud cooperates with one of the branches of the guide 118 to form a hard point during the operation of the latch 120 of the configuration of the figure 11 to that of the figure 12 , under the effect of the traction T. This nipple maintains firstly the rotary key in "open" position and secondly, it prevents the bolt 123 to return by simply vibration of the plate 9 under the effect of The point at which the pin 127D passes under the branch of the guide 118 is detected by the user who then perceives that the bolt 123 is in a configuration where it cooperates effectively with the heel 72 of the cheek 7.

On relève que le guide 118 comprend deux branches car il permet le montage d'un loquet 120 configuré à l'inverse de celui représenté sur les figures 10 à 13 pour coopérer avec la joue du coffre tunnel opposée à celle représentée sur les figures 11 à 13.It is noted that the guide 118 comprises two branches because it allows the mounting of a latch 120 configured opposite the one shown on the Figures 10 to 13 to cooperate with the cheek of the tunnel trunk opposite to that shown on the Figures 11 to 13 .

En variante, un ressort de rappel élastique du loquet 120 en position d'engagement avec une joue adjacente peut être prévu, comme envisagé pour le premier mode de réalisation.Alternatively, an elastic return spring of the latch 120 in the engagement position with an adjacent cheek may be provided, as envisaged for the first embodiment.

Les pièces 110, 120A et 120B sont chacune monobloc et moulées en matière plastique.Parts 110, 120A and 120B are each one-piece and molded of plastic.

Comme cela ressort de la figure 14, les parties 120A et 120B peuvent également être moulées en matière plastique monobloc en remplaçant la zone d'articulation 121D/ 127A par une charnière-film 120C qui relie ces parties. Sur cette figure 14, l'embase 110 est identique à celle du deuxième mode de réalisation. Le loquet 120 est une pièce monobloc réalisée en laissant une faible section de matière plastique, qui constitue la charnière-film 120C, relier l'organe 120A, monté mobile en rotation autour du pion 112, et la tirette 120B articulée sur cet organe au niveau de la charnière-film. La charnière-film 120C est adjacente à une première extrémité 127A de la languette 127 qui forme la tirette 120B et dont la deuxième extrémité 127B est conformée en poignée.As is apparent from the figure 14 the portions 120A and 120B may also be molded from one-piece plastic by replacing the hinge region 121D / 127A with a hinge-film 120C which connects these portions. On this figure 14 , the base 110 is identical to that of the second embodiment. The latch 120 is a one-piece piece made by leaving a small section of plastic material, which constitutes the film hinge 120C, connect the member 120A rotatably mounted around the pin 112, and the pull tab 120B articulated on this member at the level of the hinge-film. The film hinge 120C is adjacent a first end 127A of the tab 127 which forms the pull tab 120B and the second end 127B is shaped handle.

La matière synthétique choisie pour mouler le loquet 120 est adaptée à la création de la charnière-film 120C. Il peut s'agir de polypropylène, de polyéthylène ou de tout autre matériau ayant capacité à subir des flexions alternées sans se rompre.The synthetic material chosen to mold the latch 120 is adapted to the creation of the 120C film hinge. It may be polypropylene, polyethylene or any other material having the ability to flex alternately without breaking.

Le bord supérieur 127C de la partie courante de la languette 127, entre ses extrémités 127A et 127B, est pourvu de deux tétons 127D et 127E en saillie vers le haut, comme le téton 127D du deuxième mode de réalisation. Ces tétons 127D et 127E coopèrent avec l'une des branches du guide 118 pour constituer chacun un point dur lors de la manoeuvre du loquet 120 d'une configuration analogue à celle de la figure 11 à une configuration analogue à celle de la figure 12. Ces tétons maintiennent la clé rotative respectivement en portion « ouverte » et « fermée ». Comme dans le deuxième mode de réalisation, le point dur lors du passage des tétons sous la branche du guide 118 est détecté par l'utilisateur qui perçoit, dans un sens, que le pêne 123 est dans une configuration où il coopère avec un talon équivalent au talon 72 du deuxième mode de réalisation et, dans l'autre sens, que son loquet est bien en position ouverte.The upper edge 127C of the running portion of the tongue 127, between its ends 127A and 127B, is provided with two protruding pins 127D and 127E, like the pin 127D of the second embodiment. These pins 127D and 127E cooperate with one of the branches of the guide 118 to each constitute a hard point when operating the latch 120 of a configuration similar to that of the figure 11 to a configuration similar to that of the figure 12 . These nipples hold the rotary key respectively in "open" and "closed" portions. As in the second embodiment, the hard point during the passage of the pins under the branch of the guide 118 is detected by the user who perceives, in a sense, that the bolt 123 is in a configuration where it cooperates with an equivalent heel at the heel 72 of the second embodiment and, in the other direction, that its latch is in the open position.

Pour le reste, ce troisième mode de réalisation est identique au deuxième et fonctionne de la même façon.For the rest, this third embodiment is identical to the second and works in the same way.

Dans tous le cas, les dispositifs d'immobilisation de la plaque 9 ne nécessitent pas de modifier structurellement cette plaque et demeurent particulièrement discrets une fois la plaque immobilisée par rapport aux joues d'extrémité 7 et 8 du coffre tunnel 2.In any case, the immobilization devices of the plate 9 do not require to structurally modify this plate and remain particularly discrete once the plate immobilized with respect to the end cheeks 7 and 8 of the tunnel box 2.

L'invention est utilisable dans le cas où un seul dispositif d'immobilisation de la plaque 9 est monté sur un seul de ses bords transversaux 97 et 98, son autre bord étant immobilisé par un autre moyen par rapport à la joue adjacente.The invention is usable in the case where a single immobilizer of the plate 9 is mounted on only one of its transverse edges 97 and 98, its other edge being immobilized by another means relative to the adjacent cheek.

Selon un autre mode de réalisation qui n'est pas représenté, le pion 112 peut être fixé, directement ou par l'intermédiaire d'un support, sur la paroi supérieure 91 de la plaque de fermeture 9. Par exemple, le pion 112 peut être planté dans la paroi 91 sans utiliser de support. La paroi 92 n'est alors pas perforée en regard du pion 112. Dans ce cas, le loquet 120 peut être solidaire en rotation du pion 112 qui tourne dans un orifice ménagé dans la paroi 91. En particulier, les parties 112 et 120 de la clé de verrouillage peuvent alors être monobloc.According to another embodiment which is not shown, the pin 112 can be fixed, directly or via a support, to the upper wall 91 of the closure plate 9. For example, the pin 112 can to be planted in the wall 91 without using a support. The wall 92 is then not perforated opposite the pin 112. In this case, the latch 120 may be integral in rotation with the pin 112 which rotates in a hole in the wall 91. In particular, the parts 112 and 120 of the locking key can then be integral.

Selon une autre variante, le pion 112 peut être solidaire du support 120 et reçu dans un palier formé sur le support 111.According to another variant, the pin 112 may be secured to the support 120 and received in a bearing formed on the support 111.

Dans tous les modes de réalisation, le pion 112 est monté sur la plaque 9, au voisinage de sa paroi supérieure 91.In all embodiments, the pin 112 is mounted on the plate 9, in the vicinity of its upper wall 91.

L'invention est représentée sur les figures dans le cadre d'une installation de fermeture. Dans ce cas, le tablier du volet ou de la porte peut être souple ou formé de lattes. L'invention est également applicable dans une installation de protection solaire, indépendamment du type exact du store utilisé. On citera pour exemple un store vénitien qui vient s'empiler dans le coffre au lieu de s'enrouler autour d'un tube, les cordons de ce store s'enroulant alors sur un arbre prévu à cet effet.The invention is shown in the figures in the context of a closure installation. In this case, the apron of the shutter or the door may be flexible or formed of slats. The invention is also applicable in a solar protection installation, regardless of the exact type of blind used. For example, a venetian blind is stacked in the trunk instead of wrapping around a tube, the cords of this blind then winding on a tree provided for this purpose.

Les caractéristiques techniques des différents modes de réalisation et variantes envisagés ci-dessus peuvent être combinées entre elles.The technical characteristics of the various embodiments and variants envisaged above can be combined with each other.
