Description

BOUCHE D'ASPIRATION POUR INSTALLATION D'ASPIRATIONSUCTION NOZZLE FOR SUCTION SYSTEM
INTEGREEINTEGRATED
La présente invention concerne les installations d'aspiration intégrée ; elle concerne plus particulièrement une bouche ou prise d'aspiration destinée à équiper de telles installations.The present invention relates to integrated suction installations; it relates more particularly to a mouth or suction outlet intended to equip such installations.
Les installations d'aspiration intégrée permettent le nettoyage des locaux par aspiration des poussières en supprimant les inconvénients de l'aspirateur classique. Elles comprennent : - une centrale d'aspiration associée à un collecteur de poussières et autres débris,The integrated suction systems allow cleaning of the premises by dust extraction while eliminating the drawbacks of the conventional vacuum cleaner. They include: - a central vacuum unit associated with a collector of dust and other debris,
- un réseau de canalisations intégré dans les placards, faux-plafonds, doubles-cloisons ou sous-sols du local ou de l'habitation équipée, et - des bouches d'aspiration judicieusement réparties, encastrées et posées dans les cloisons.- a network of pipes integrated into the cupboards, false ceilings, double partitions or basements of the room or of the equipped dwelling, and - suction outlets judiciously distributed, embedded and installed in the partitions.
Le réseau de canalisations relie la centrale aux bouches d'aspiration ; un flexible d'aspiration de grande longueur (7,5 m environ) associé à un suceur d'extrémité est connecté à volonté sur les bouches lorsque l'on désire nettoyer le sol. Le flexible déclenche l'aspiration simultanément à son branchement sur les bouches d'aspiration.The network of pipes connects the central to the suction outlets; a very long suction hose (around 7.5 m) associated with an end nozzle is connected at will to the outlets when it is desired to clean the floor. The hose starts suction simultaneously with its connection to the suction outlets.
Ce principe d'aspiration intégrée est très silencieux car on choisit la place de la centrale dans une pièce secondaire. D'autre part, grâce au flexible souple et léger on peut évoluer en toute liberté dans le local ou l'habitation, sans avoir à traîner un poids important et sans risque pour les meubles ou la décoration. Les bouches d'aspiration qui sont encastrées dans les murs pour recevoir le flexible d'aspiration ont généralement une forme rectangulaire ; elles sont constituées d'une embase munie d'un orifice adapté pour recevoir, côté extérieur, l'embout du flexible d'aspiration. Côté intérieur, cet orifice se raccorde sur le tube conducteur d'aspiration qui se prolonge par une canalisation en PVC débouchant dans la centrale. Sur l'extérieur, l'orifice de la bouche d'aspiration est associé à un couvercle d'obturation étanche, généralement monté sur charnières à ressort.This principle of integrated suction is very quiet because we choose the place of the central unit in a secondary room. On the other hand, thanks to the flexible and light flexible one can move freely in the room or the house, without having to drag a significant weight and without risk for furniture or decoration. The suction outlets which are built into the walls to receive the suction hose generally have a rectangular shape; they consist of a base provided with an orifice adapted to receive, on the outside, the end of the suction hose. On the interior side, this orifice is connected to the suction conductor tube which is extended by a PVC pipe opening into the central unit. On the outside, the orifice of the suction mouth is associated with a tight shutter cover, generally mounted on spring hinges.
La pose des bouches d'aspiration connues jusqu'à maintenant n'est pas très facile à réaliser, notamment de par la structure du système de raccordement entre le tube conducteur d'aspiration et l'orifice de 1 ' embase .The installation of the suction ports known up to now is not very easy to carry out, in particular because of the structure of the connection system between the suction conducting tube and the orifice of the base.
D'autre part, les couvercles d'obturation des bouches d'aspiration classiques sont adaptés, en taille et forme, à l'orifice associé. Ce couvercle est intégré dans l'encombrement général de l'embase ; au niveau de sa charnière d'articulation, il est nécessaire de conserver une ouverture ou un espace suffisant lié à ses possibilités de rotation. Cette ouverture forme un "nid à poussières" qui n'est pas très facile à nettoyer ; en outre, l'espace correspondant, sur le dessus de la bouche ou en façade, n'est pas très esthétique .On the other hand, the closing lids of conventional suction outlets are adapted, in size and shape, to the associated orifice. This cover is integrated into the overall dimensions of the base; at its articulation hinge, it is necessary to keep an opening or a sufficient space linked to its possibilities of rotation. This opening forms a "dust nest" which is not very easy to clean; in addition, the corresponding space, on the top of the mouth or on the front, is not very aesthetic.
La présente invention a pour but de pallier à ces inconvénients en proposant une bouche ou prise d'aspiration pour installation d'aspiration intégrée, qui présente une structure originale. La pose de cette bouche s'effectue très facilement et elle peut tout aussi aisément être démontée. Cette bouche est en outre très esthétique et évite au maximum la présence de rainures ou d'ouvertures.The purpose of the present invention is to overcome these drawbacks by proposing a mouth or intake for an integrated suction installation, which has an original structure. The installation of this mouth is very easy and it can just as easily be disassembled. This mouth is also very aesthetic and minimizes the presence of grooves or openings.
Cette bouche d'aspiration est du type comportant une embase munie d'un orifice adapté pour recevoir, d'un côté, l'embout du flexible d'aspiration, et sur lequel se raccorde, de l'autre côté, le tube conducteur d'aspiration.This suction mouth is of the type comprising a base provided with an orifice adapted to receive, on one side, the end piece of the suction hose, and to which, on the other side, the conductive tube d aspiration.
Selon l'invention, la bouche comporte une pièce de connexion, entre le tube conducteur d'aspiration et le cylindre qui prolonge vers l'arrière l'orifice de l'embase. Cette pièce de connexion se présente sous la forme d'un cylindre associé à une platine d'extrémité munie d'un orifice concentrique audit cylindre. Le cylindre de la pièce de connexion a un diamètre adapté pour pouvoir être emmanché dans ou sur le tube conducteur (ou éventuellement un accessoire de raccordement) ; l'orifice de la platine associée a un diamètre qui correspond sensiblement au diamètre extérieur du cylindre qui prolonge l'orifice de l'embase, et cette embase est munie d'orifices qui permettent sa fixation par vis sur la platine de la pièce de connexion.According to the invention, the mouth comprises a connection piece, between the suction conducting tube and the cylinder which extends the orifice of the base towards the rear. This connection piece is in the form of a cylinder associated with an end plate provided with an orifice concentric with said cylinder. The cylinder of the connection part has a diameter adapted to be able to be fitted into or on the conductive tube (or possibly a connection accessory); the orifice of the associated plate has a diameter which corresponds substantially to the external diameter of the cylinder which extends the orifice of the base, and this base is provided with orifices which allow its fixing by screws on the plate of the connection piece .
Selon une autre disposition, les orifices prévus dans l'embase pour sa fixation par vis sur la pièce de connexion ont une forme oblongue qui permet un réglage de positionnement.According to another arrangement, the orifices provided in the base for its fixing by screws to the connection piece have an oblong shape which allows positioning adjustment.
Selon une autre caractéristique, la bouche d'aspiration comporte un joint torique placé autour du cylindre qui prolonge l'orifice de l'embase, et qui s'interpose entre la platine de la pièce de connexion et la face intérieure de ladite embase.According to another characteristic, the suction mouth has an O-ring placed around of the cylinder which extends the orifice of the base, and which is interposed between the plate of the connection piece and the inner face of said base.
Toujours selon l'invention, la bouche d'aspiration comporte :Still according to the invention, the suction mouth comprises:
- un couvercle d'obturation plan dont la forme et les dimensions correspondent sensiblement à celles de l'embase, lequel couvercle comporte des flancs latéraux destinés à venir recouvrir les côtés de ladite embase; ces flancs se prolongent par des ailes latérales supérieures dont les faces internes sont raccordées par un axe et ,- A planar shutter cover whose shape and dimensions correspond substantially to those of the base, which cover has lateral flanks intended to cover the sides of said base; these flanks are extended by upper lateral wings whose internal faces are connected by an axis and,
- une embase munie, dans sa partie supérieure, d'une poutre horizontale en saillie qui s'étend sur toute sa largeur et aux extrémités de laquelle sont prévus des orifices destinés au passage de l'axe du couvercle pour former la charnière d'articulation.- a base provided, in its upper part, with a horizontal projecting beam which extends over its entire width and at the ends of which are provided orifices intended for the passage of the axis of the cover to form the articulation hinge .
Selon une disposition préférée, l'axe qui raccorde les faces internes des ailes supérieures du couvercle est constitué d'un cylindre métallique rapporté, en deux parties. Ce cylindre comporte des orifices d'extrémités qui permettent l'insertion d'ergots monoblocs prévus au niveau des faces internes desdites ailes supérieures, et les deux parties dudit cylindre sont solidarisées par un assemblage mécanique axial, type tenon-mortaise. Cette structure particulière renforce la charnière d'ar iculation du couvercle sur l'embase ; elle facilite également l'ouverture et la fermeture dudit couvercle.According to a preferred arrangement, the axis which connects the internal faces of the upper wings of the cover consists of an attached metal cylinder, in two parts. This cylinder has end orifices which allow the insertion of one-piece lugs provided at the internal faces of said upper wings, and the two parts of said cylinder are secured by an axial mechanical assembly, of the tenon-mortise type. This particular structure strengthens the hinge of articulation of the cover on the base; it also facilitates the opening and closing of said cover.
Selon une autre disposition de l'invention, les orifices prévus aux extrémités de la poutre horizontale sont ouverts sur l'arrière pour faciliter le montage et le démontage du couvercle sur l'embase.According to another provision of the invention, the holes provided at the ends of the horizontal beam are open on the rear to facilitate mounting and dismounting of the cover on the base.
Selon une autre disposition de l'invention, l'embase de la bouche d'aspiration comporte une poutre ayant une forme sensiblement parallelepipedique. Cette poutre est munie d'un chanfrein sur toute la longueur de son angle frontal supérieur ; ce chanfrein est adapté pour ne pas gêner - la rotation du couvercle autour de son axe d'articulation.According to another arrangement of the invention, the base of the suction mouth comprises a beam having a substantially parallelepiped shape. This beam is provided with a chamfer over the entire length of its upper frontal angle; this chamfer is adapted so as not to obstruct - the rotation of the cover around its axis of articulation.
Selon une autre caractéristique, l'angle supérieur arrière des ailes latérales du couvercle est biseauté. Cette disposition est prévue pour ne pas gêner la rotation du couvercle, lors de son ouverture ou de sa fermeture.According to another characteristic, the upper rear corner of the lateral wings of the cover is beveled. This arrangement is provided so as not to hinder the rotation of the cover, when it is opened or closed.
Selon une autre disposition, le couvercle comporte un flanc inférieur qui permet le recouvrement de la bordure inférieure de l'embase, en position fermée. Ce flanc inférieur comporte une réservation qui sert à la prise des doigts en vue de l'ouverture du couvercle .According to another arrangement, the cover has a lower flank which allows the lower edge of the base to be covered, in the closed position. This lower side has a reservation which is used for gripping the fingers in order to open the cover.
Selon une autre disposition de l'invention, la face interne du couvercle comporte un ergot de positionnement d'un joint plat destiné à obturer l'orifice de l'embase de façon étanche. Ce joint est maintenu en position par une rondelle de retenue dont la face en regard dudit joint se présente sous la forme d'une succession de couronnes d'épaisseur décroissante du centre vers l'extérieur, pour conférer une possibilité de mouvement audit joint, sur sa périphérie . La bouche d'aspiration selon l'invention présente l'intérêt de ne nécessiter aucun scellement pour la pose. En outre, de par sa structure, le couvercle ne nécessite aucun ressort de rappel pour assurer son repositionnement correct en position fermée. D'autre part, le couvercle peut très facilement être remplacé par un autre, en cas de détérioration ou si on désire changer l'esthétique de l'ensemble.According to another arrangement of the invention, the internal face of the cover comprises a lug for positioning a flat seal intended to close the orifice of the base in a sealed manner. This seal is held in position by a retaining washer whose facing face of said seal is in the form of a succession of crowns of decreasing thickness from the center towards the outside, to give a possibility of movement to said seal, on its periphery. The suction mouth according to the invention has the advantage of requiring no sealing for installation. In addition, due to its structure, the cover does not require any return spring to ensure its correct repositioning in the closed position. On the other hand, the cover can very easily be replaced by another, in case of deterioration or if one wishes to change the aesthetics of the assembly.
Un autre intérêt de cette bouche d'aspiration réside dans le fait que l'ouverture du couvercle peut s'effectuer sur 180° ; aucun élément ne fonctionne sous contrainte, on ne constate pas de déformation en utilisation et on maintient une bonne étanchéité. Dans les systèmes antérieurs munis d'un ressort de rappel, l'ouverture du couvercle n'est que partielle ; il y a des possibilités de forcement sur le couvercle et les déformations occasionnées nuisent à l'étanchéité.Another advantage of this suction mouth lies in the fact that the opening of the cover can be carried out over 180 °; no element operates under stress, there is no deformation in use and a good seal is maintained. In previous systems provided with a return spring, the opening of the cover is only partial; there are possibilities of forcing on the cover and the deformations caused affect the sealing.

Telle qu'on l'a représentée sur les figures 1 à 4, la bouche d'aspiration est constituée d'une embaseAs shown in Figures 1 to 4, the suction mouth consists of a base
1 réalisée par moulage de matériau plastique, genre PVC ABS ou similaire, et qui se présente sous une forme générale carrée. Cette embase 1 consiste en un plateau1 produced by molding plastic material, such as PVC ABS or similar, and which has a generally square shape. This base 1 consists of a plate
2 au centre duquel est prévu un orifice 3 qui se prolonge, vers l'arrière, par un cylindre monobloc 4.2 in the center of which is an orifice 3 which is extended, towards the rear, by a monobloc cylinder 4.
Les dimensions de l'orifice 3 et du cylindre 4 associé sont adaptées pour permettre la réception, sur l'avant, de l'embout 5 du flexible d'aspiration 5 (figure 4).The dimensions of the orifice 3 and of the associated cylinder 4 are adapted to allow reception, on the front, of the nozzle 5 of the suction hose 5 (FIG. 4).
Ces dimensions sont également adaptées pour permettre le raccordement, sur l'arrière, du tube conducteur d'aspiration 6 (figure 1), ou de tout autre accessoire de raccordement destiné à conduire la n poussière et autres débris jusqu'à la centrale de l'installation ; ce raccordement est réalisé par l'intermédiaire d'une pièce de connexion 7.These dimensions are also adapted for connection, on the back, the driver suction tube 6 (Figure 1), or any other accessory connection for driving the n dust and other debris to the center of installation; this connection is made by means of a connection piece 7.
On a représenté sur la figure 1, la bouche d'aspiration selon l'invention, montée sur une cloison de réception 8.FIG. 1 shows the suction mouth according to the invention, mounted on a receiving partition 8.
La cloison 8 est percée pour recevoir la bouche d'aspira ion. L'embase 1 est plaquée contre cette cloison 8, au niveau de l'orifice 9 correspondant. Le cylindre 4 pénètre en partie dans cet orifice 9 et il vient se raccorder sur le tube conducteur 6, lequel est lui-même connecté à la centrale d'aspiration, non représentée. Les cylindres 4 et 6 ont des diamètres différents ; ils sont raccordés par la pièce de connexion 7 qui se présente sous la forme d'un cylindre 10 associé à une platine d'extrémité 11. La platine 11 s'étend dans un plan perpendiculaire à celui de l'axe 12 du cylindre 10 ; elle comporte un orifice central 13 dont le centre correspond audit axe 12.The partition 8 is drilled to receive the suction mouth. The base 1 is pressed against this partition 8, at the level of the corresponding orifice 9. The cylinder 4 partially penetrates this orifice 9 and it is connected to the conductive tube 6, which is itself connected to the central vacuum unit, not shown. The cylinders 4 and 6 have different diameters; they are connected by the connection piece 7 which is in the form of a cylinder 10 associated with an end plate 11. The plate 11 extends in a plane perpendicular to that of the axis 12 of the cylinder 10; it has a central orifice 13, the center of which corresponds to said axis 12.
Le diamètre intérieur du cylindre 10 de la pièce de connexion 7 correspond sensiblement au diamètre extérieur du tube conducteur 6. Le cylindre 10 s'emmanche sur le tube 6 et leur solidarisation est réalisée au moyen d'une colle adaptée.The inside diameter of the cylinder 10 of the connection piece 7 corresponds substantially to the outside diameter of the conductive tube 6. The cylinder 10 is fitted onto the tube 6 and they are joined together using an appropriate adhesive.
L'orifice 13 de la platine 11 a un diamètre qui correspond sensiblement au diamètre extérieur du cylindre 4. Ce dernier vient s'emmancher dans l'orifice 13 de la platine de connexion 7 et les trois cylindres 4, 10 et 6 s'étendent de façon co-axiale. La solidarisation de l'embase 1 sur la pièce de connexion 7 s'effectue au moyen de vis 15, par l'intermédiaire d'orifices oblongs 16 réalisés dans le plateau 2. Ces orifices oblongs 16 sont visibles sur la figure 2 ; ils sont au nombre de quatre répartis autour de l'orifice central 3. Deux des orifices oblongs 16 s'étendent horizontalement ; les deux autres sont orientés verticalement.The orifice 13 of the plate 11 has a diameter which corresponds substantially to the external diameter of the cylinder 4. The latter comes to be fitted in the orifice 13 of the connection plate 7 and the three cylinders 4, 10 and 6 extend co-axially. The connection of the base 1 to the connection piece 7 is effected by means of screws 15, by means of oblong holes 16 made in the plate 2. These oblong holes 16 are visible in FIG. 2; they are four in number distributed around the central orifice 3. Two of the oblong orifices 16 extend horizontally; the other two are oriented vertically.
Pour faciliter l'opération de fixation, il est prévu des avant-trous dans la platine 11 de la pièce de connexion 7 ; la forme oblongue des orifices 16 permet de faciliter la fixation et de rattraper les désalignements éventuels.To facilitate the fixing operation, pilot holes are provided in the plate 11 of the connection piece 7; the oblong shape of the orifices 16 makes it easier to fix and make up for any misalignments.
Pour compléter 1 ' étanchéité , un joint torique 17 est interposé entre la platine 11 et la face intérieure du plateau 2 de l'embase 1. Ce joint torique 17 est placé autour du cylindre 4.To complete the seal, an O-ring 17 is interposed between the plate 11 and the inner face of the plate 2 of the base 1. This O-ring 17 is placed around the cylinder 4.
Sur la bordure supérieure de l'embase 1, on remarque la présence d'une poutre horizontale 20 qui déborde et s'étend en saillie au-delà du plateau 2. La poutre 20 a une forme générale parallelepipedique; ses flancs latéraux d'extrémités 21 comportent des orifices 22 en vis-à-vis qui sont ouverts en 23 pour déboucher sur l'arrière. Ces orifices 22 sont disposés légèrement en avant du plan défini par le plateau 2.On the upper edge of the base 1, there is the presence of a horizontal beam 20 which projects and projects beyond the plate 2. The beam 20 has a generally parallelepiped shape; its lateral flanks of ends 21 have orifices 22 facing each other which are open at 23 to lead to the rear. These orifices 22 are arranged slightly in front of the plane defined by the plate 2.
La poutre 20 est définie, figure 2, par une face supérieure 24, une face frontale 25 et une face inférieure 26 qui se raccorde au plateau 1. Sur cette figure 2, on remarque que l'angle frontal supérieur 27 de la poutre 20 comporte un chanfrein sur toute sa longueur. Ce chanfrein permet de "casser" l'angle correspondant.The beam 20 is defined, FIG. 2, by an upper face 24, a front face 25 and a lower face 26 which is connected to the plate 1. In this FIG. 2, it is noted that the upper front angle 27 of the beam 20 comprises a chamfer all over its length. This chamfer makes it possible to "break" the corresponding angle.
Toujours sur la figure 2, on remarque le couvercle 30 qui est destiné à venir coiffer l'embase 1 en vue, notamment, d'obturer l'orifice 3. Ce couvercle 30 est réalisé par moulage de matériau plastique genre PVC ABS, ou similaire ; il a une forme générale carrée correspondant sensiblement à celle de 1 ' embase 1.Still in FIG. 2, there is the cover 30 which is intended to cover the base 1 with a view, in particular, to closing the orifice 3. This cover 30 is produced by molding of plastic material such as PVC ABS, or the like ; it has a generally square shape corresponding substantially to that of the base 1.
Le couvercle 30 est constitué d'un plateau 31 bordé, latéralement, par des flancs 32 et 33 qui s'étendent vers l'arrière et qui sont destinés à venir recouvrir les côtés de l'embase 1. Ces flancs latéraux 32 et 33 se prolongent, vers le haut, par des ailes supérieures latérales, respectivement 34 et 35, dont la longueur correspond sensiblement à l'épaisseur de la poutre 20 de l'embase, c'est-à-dire à l'espacement entre sa face supérieure 24 et sa face inférieure 26.The cover 30 consists of a plate 31 bordered, laterally, by flanks 32 and 33 which extend rearward and which are intended to come to cover the sides of the base 1. These lateral flanks 32 and 33 are extend, upwards, by lateral upper wings, respectively 34 and 35, the length of which corresponds substantially to the thickness of the beam 20 of the base, that is to say to the spacing between its upper face 24 and its underside 26.
Les faces internes des ailes 34 et 35 sont raccordées par un cylindre 36 ma érialisant l'axe d'articulation 37 du couvercle 30 sur l'embase 1.The internal faces of the wings 34 and 35 are connected by a cylinder 36 ma erizing the articulation axis 37 of the cover 30 on the base 1.
L'axe 36 est détaillé sur la figure 5. Il se présente sous la forme d'un cylindre métallique rapporté, muni d'orifices axiaux 37 à chacune de ses extrémités. Les orifices 37 permettent le positionnement de l'axe 36 sur des ergots cylindriques 38 en forme de tourillons réalisés monoblocs au niveau de la face interne des ailes 34 et 35 et disposés en vis-à-vis . Le cylindre 36 peut avoir un diamètre de l'ordre de 4 mm ; le diamètre des ergots 38 peut être de l'ordre de 2,5 mm.The axis 36 is detailed in FIG. 5. It is in the form of an attached metal cylinder, provided with axial orifices 37 at each of its ends. The orifices 37 allow the positioning of the axis 36 on cylindrical lugs 38 in the form of trunnions made in one piece at the level of the internal face of the wings 34 and 35 and arranged opposite. The cylinder 36 can have a diameter of the order of 4 mm; the diameter of the pins 38 can be of the order of 2.5 mm.
Etant donné la rigidité du couvercle 32, et plus particulièrement des ailes 34 et 35, le cylindre 36 se présente avantageusement en deux parties complémentaires 39 et 40 destinées à être solidarisées par un assemblage mécanique axial type tenon 41- mortaise 42.Given the rigidity of the cover 32, and more particularly of the wings 34 and 35, the cylinder 36 is advantageously in two complementary parts 39 and 40 intended to be joined together by an axial mechanical assembly of the tenon 41- mortise 42 type.
Le montage de l'axe 36 sur le couvercle 32 s'effectue dans un premier temps en positionnant chaque partie d'axe 39 et 40 sur l'ergot 38 correspondant, par l'intermédiaire des orifices d'extrémités 37. Les deux parties d'axe 39 et 40 sont ensuite disposées dans le prolongement l'une de l'autre et maintenues bout à bout par l'intermédiaire de l'assemblage tenon- mortaise 41 , 42.The mounting of the axis 36 on the cover 32 is carried out firstly by positioning each part of the axis 39 and 40 on the corresponding lug 38, by means of the end orifices 37. The two parts d the axis 39 and 40 are then placed in the extension of one another and held end to end by means of the tenon-mortise assembly 41, 42.
Une telle construction assure une articulation renforcée du couvercle 30 sur l'embase 1.Such a construction ensures a reinforced articulation of the cover 30 on the base 1.
L'espacement entre les ailes 34 et 35 est légèrement supérieur à celui qui sépare les deux flancs latéraux 21 de la poutre 20. Le cylindre 36 est adapté pour venir s'insérer dans les orifices 22 de la poutre 20 en vue de former une charnière d'articulation autour de l'axe 37. Cette insertion, pour le positionnement du couvercle 30 sur l'embase 1 est réalisée grâce aux ouvertures arrière 23 prévues dans le prolongement desdits orifices 22.The spacing between the wings 34 and 35 is slightly greater than that which separates the two lateral flanks 21 of the beam 20. The cylinder 36 is adapted to be inserted into the orifices 22 of the beam 20 in order to form a hinge articulation around the axis 37. This insertion, for positioning the cover 30 on the base 1 is carried out thanks to the rear openings 23 provided in the extension of said orifices 22.
Dans sa partie inférieure, le couvercle 30 comporte un flanc d'extrémité 43 qui raccorde les flancs latéraux 32, 33 et qui est adapté pour venir recouvrir la bordure inférieure de l'embase 1. Le flanc 43 s'étend perpendiculairement au plateau 31 ; dans sa partie médiane, il comporte une réservation 44 qui définit une zone de préhension destinée à l'ouverture du couvercle. Cette réservation 44 peut consister en une simple encoche prise dans l'épaisseur du flanc 43.In its lower part, the cover 30 has an end flank 43 which connects the lateral sides 32, 33 and which is adapted to cover the lower edge of the base 1. The side 43 extends perpendicular to the plate 31; in its middle part, it has a reservation 44 which defines a grip zone intended for opening the cover. This reservation 44 may consist of a simple notch taken in the thickness of the sidewall 43.
D'autre part, sur la figure 2, on remarque que l'angle supérieur arrière 45 des ailes 34 et 35 est biseauté. La découpe correspondante est aménagée, comme on le verra plus loin, pour ne pas gêner l'ouverture et la fermeture du couvercle 30, une fois la bouche d'aspiration en place contre la cloison de réception.On the other hand, in Figure 2, we note that the upper rear angle 45 of the wings 34 and 35 is beveled. The corresponding cutout is arranged, as will be seen below, so as not to hinder the opening and closing of the cover 30, once the suction mouth is in place against the receiving partition.
Les figures 3 et 4 montrent le couvercle 30 monté sur l'embase 1 par insertion de l'axe 36 dans les orifices latéraux de réception 22. Cette insertion est réalisée avant le montage de l'embase 1 contre la cloison du local. On comprend bien qu'une fois l'embase plaquée contre ladite cloison, le couvercle 30 s'articule autour de son axe de rotation 37 sans possibilité de déboîtement.Figures 3 and 4 show the cover 30 mounted on the base 1 by insertion of the pin 36 in the side receiving holes 22. This insertion is carried out before mounting the base 1 against the room partition. It is well understood that once the base pressed against said partition, the cover 30 is articulated around its axis of rotation 37 without the possibility of disengagement.
Comme on peut le voir encore sur les figuresAs can still be seen in the figures
3 et 4, en position fermée, le couvercle 30 masque complètement l'embase 1, sur les côtés et dans la partie inférieure. Seule la poutre 20 est accessible dans la partie supérieure. Dans cette position fermée, le plateau 31 du couvercle 30 s'étend dans le plan de la face frontale 25 de la poutre 20. Ces deux plans3 and 4, in the closed position, the cover 30 completely hides the base 1, on the sides and in the lower part. Only the beam 20 is accessible in the upper part. In this closed position, the plate 31 of the cover 30 extends in the plane of the front face 25 of the beam 20. These two planes
25 et 31 sont rapprochés au maximum l'un de l'autre pour éviter la présence d'une ouverture ou d'un espace trop important .25 and 31 are as close as possible to each other to avoid the presence of a too large opening or space.
A cet effet, et comme on peut le voir sur la figure 6, l'angle intérieur de la bordure supérieure 46 du plateau 31 est chanfreine sur toute sa longueur, entre les ailes latérales 34 et 35. Ce chanfrein est adapté pour permettre le passage du couvercle 30 autour de l'angle frontal inférieur 47 de la poutre 20, tout en limitant l'espacement entre ladite poutre et ladite bordure supérieure 46. On obtient ainsi un ensemble esthétique et très facile à nettoyer étant donné la quasi absence d'ouvertures ou de logements dans lesquels pourrait s'insérer la poussière.To this end, and as can be seen in FIG. 6, the internal angle of the upper edge 46 of the plate 31 is chamfered over its entire length, between the lateral wings 34 and 35. This chamfer is adapted to allow passage of the cover 30 around the lower front angle 47 of the beam 20, while limiting the spacing between said beam and said upper edge 46. This thus gives an aesthetic assembly and very easy to clean given the almost absence of openings or housing in which the dust could fit.
Si on désire utiliser la bouche d'aspiration pour y loger l'embout 5 du flexible d'aspiration, figure 4, il suffit de faire pivoter le couvercle 30 autour de son axe d'articulation 37. Cette opération est possible grâce aux chanfreins 27 et 45 précités qui évitent la présence de zones en saillie susceptibles de former des butées de limitation de course .If one wishes to use the suction mouth to accommodate the end piece 5 of the suction hose, FIG. 4, it suffices to rotate the cover 30 around its articulation axis 37. This operation is possible thanks to the chamfers 27 and 45 aforementioned which avoid the presence of projecting zones capable of forming travel limitation stops.
De préférence, les angles extérieurs qui raccordent le plateau 31 et ses flancs 32, 33 et 43 sont biseautés de la même façon que l'angle 27 de la poutre 20, pour améliorer l'esthétique de l'ensemble.Preferably, the external angles which connect the plate 31 and its sides 32, 33 and 43 are bevelled in the same way as the angle 27 of the beam 20, to improve the aesthetics of the assembly.
Sur la face interne du plateau 31, figure 6, on a prévu un ergot monobloc 48 sur lequel vient se positionner le joint plat 49 destiné à étancher l'orifice 3 de l'embase lorsque le couvercle est en position fermée. Le joint- 49 peut consister en une pastille de matériau souple, type caoutchouc, dont le diamètre est légèrement supérieur à celui dudit orifice 3.On the internal face of the plate 31, FIG. 6, a one-piece lug 48 is provided on which the flat seal 49 is positioned to seal the orifice 3 of the base when the cover is in the closed position. The seal 49 may consist of a pastille of flexible material, rubber type, the diameter of which is slightly greater than that of said orifice 3.
Ce joint plat d'étanchéité 49 est maintenu en position par une rondelle de retenue 50, réalisée en matériau plastique et emmanchée à force sur l'ergot 48. La rondelle 50 a un diamètre suffisant pour éviter l'arrachage du joint 49 par l'aspiration d'air. Comme on l'a représentée sur la figure 7, la face de cette _ rondelle 50 qui se situe en regard du joint plat 49 a une configuration générale en escalier ; cette face se présente en effet sous la forme d'une succession de couronnes 51 d'épaisseur décroissante du centre vers l'extérieur. Cette forme particulière permet , - d'avoir une grande surface de retenue tout en conférant une possibilité de mouvement audit joint 49, sur sa périphérie, pour améliorer les possibilités d ' étanchement .This flat seal 49 is held in position by a retaining washer 50, made of plastic material and force fitted on the lug 48. The washer 50 has a diameter sufficient to prevent the seal 49 from being torn off by the air intake. As shown in FIG. 7, the face of this washer 50 which is situated opposite the flat seal 49 has a general staircase configuration; this face is in fact in the form of a succession of crowns 51 of decreasing thickness from the center outwards. This particular shape allows, - to have a large retaining surface while giving a possibility of movement to said seal 49, on its periphery, to improve the possibilities of sealing.
Le maintien en position de la rondelle 50 peut êtreMaintaining the washer 50 in position can be
20 complété par la présence de déformations 52 réalisées à l'extrémité de l'ergot 48 et qui forment des butées de retenue. Ces butées 52 peuvent être obtenues au moyen d'un système de chauffage apte à entraîner la fusion du matériau plastique.20 completed by the presence of deformations 52 made at the end of the lug 48 and which form retaining stops. These stops 52 can be obtained by means of a heating system capable of causing the plastic material to melt.
25 A noter que le montage particulier du couvercle 30 sur l'embase 1 peut être utilisé indépendamment du système d'assemblage de la bouche d'aspiration sur le tube conducteur 6 au moyen de la pièce de connexion 7. La structure particulière décrite ci-avant facilite grandement la pose des bouches d'aspiration sur les tubes conducteurs de l'installation d'aspiration intégrée ; elle permet également de faciliter le démontage et le réassemblage, en cas de détérioration d'un des éléments constitutifs ou si on désire surveiller, vérifier ou nettoyer les pièces inaccessibles de l'extérieur.25 Note that the particular mounting of the cover 30 on the base 1 can be used independently of the system for assembling the suction mouth on the conductive tube 6 by means of the connection piece 7. The particular structure described above greatly facilitates the installation of the suction outlets on the conductive tubes of the integrated suction installation; it also facilitates disassembly and reassembly, in the event of deterioration of one of the constituent elements or if one wishes to monitor, check or clean the parts inaccessible from the outside.
La bouche d'aspiration, selon l'invention est particulièrement adaptée aux installations d'aspiration intégrée qui utilisent un système de télécommande par transmission sonore ou autre ... (type radio par exemple) . The suction mouth according to the invention is particularly suitable for integrated suction installations which use a remote control system by sound transmission or the like ... (radio type for example).
