Description

PLAFOND ACOUSTIQUE POUR SALLE DE SPECTACLE
La présente invention se rapporte a un plafond acoustique, aisément démontable et transportable, destiné à équiper une salle de spectacle.ACOUSTICAL CEILING FOR SHOWROOM
The present invention relates to an acoustic ceiling, easily removable and transportable, intended to equip a performance hall.

Un plafond acoustique a pour rôle d'une part de- réfléchir les ondes provenant du bas vers les auditeurs, et d'autre part d'absorber les bruits parasites provenant de I'extérieur.  The role of an acoustic ceiling is on the one hand to reflect the waves coming from the bottom towards the listeners, and on the other hand to absorb parasitic noises coming from outside.

Les plafonds acoustiques connus sont composés de panneaux rigides en bois ou en matériau composite, sur le verso desquels sont éventuellement rapportés un ou plusieurs matériaux absorbants, par exemple une laine minérale. Ces plafonds sont lourds à déplacer, de sorte que pratiquement ils ne conviennent que pour une installation permanente. Known acoustic ceilings are composed of rigid panels of wood or composite material, on the back of which are optionally attached one or more absorbent materials, for example mineral wool. These ceilings are heavy to move, so that practically they are only suitable for permanent installation.

L'invention, qui vise à remédier à cet inconvénient, concerne un plafond acoustique qui, tout en possédant de bonnes caractéristiques de réflexion et absorption des sons, est facilement démontable et transportable. Il est composé de boudins pneumatiques gonflables qui sont disposés côte à côte et chacun selon un axe orthogonal à la direction de réflexion vers les auditeurs du son provenant de l'organe d'émission sonore placé sous ce plafond. The invention, which aims to remedy this drawback, relates to an acoustic ceiling which, while having good characteristics of reflection and absorption of sounds, is easily removable and transportable. It is composed of inflatable pneumatic tubes which are arranged side by side and each along an axis orthogonal to the direction of reflection towards the listeners of the sound coming from the sound emitting member placed under this ceiling.

L'invention sera bien comprise, et ses caractéristiques et autres avantages ressortiront, au cours de la description suivante d'un exemple non limitatif de réalisation de ce plafond acoustique, en référence aux dessins schématiques annexés dans lesquels
Figure 1 est une vue en perspective de ce plafond, installé dans une salle de spectacle
Figure 2 en est une coupe verticale dans le plan contenant son grand axe longitudinal
Figure 3 est une vue de dessus de ce plafond ;
Figure 4 en est une vue de face
Figure 5 montre un des points d'accrochage d'un boudin gonflable.The invention will be clearly understood, and its characteristics and other advantages will emerge during the following description of a nonlimiting example of embodiment of this acoustic ceiling, with reference to the appended schematic drawings in which
Figure 1 is a perspective view of this ceiling, installed in a performance hall
Figure 2 is a vertical section in the plane containing its major longitudinal axis
Figure 3 is a top view of this ceiling;
Figure 4 is a front view
Figure 5 shows one of the attachment points of an inflatable tube.

En se reportant aux figures 1 à 4, ce plafond acoustique 1 est destiné à être suspendu, à l'aide de câbles 2, 3 et 4, au-dessus d'une scène 20 d'une salle de spectacle (salle de concert, d'opéra, église, cathédrale, salle de plein air, etc...). Ces câbles 2 à 4 sont accrochés à une structure intermédiaire (non représentée) ou au plafond de la salle. Referring to Figures 1 to 4, this acoustic ceiling 1 is intended to be suspended, using cables 2, 3 and 4, above a stage 20 of a performance hall (concert hall, opera house, church, cathedral, open air hall, etc.). These cables 2 to 4 are hung on an intermediate structure (not shown) or on the ceiling of the room.

Ce plafond I a, en vue de dessus (figure 3), une forme de carré ou de losange à quatre côtés, dont une diagonale est confondue avec l'axe longitudinal 5 de la salle et qui est dirigé selon la direction de réflexion vers les auditeurs du son provenant de l'orchestre 6 placé sous le plafond 1. This ceiling I has, in top view (Figure 3), a square or diamond shape with four sides, one diagonal of which coincides with the longitudinal axis 5 of the room and which is directed in the direction of reflection towards the listeners of the sound coming from the orchestra 6 placed under the ceiling 1.

En vue latérale, le plafond a la forme cintrée apparente en particulier sur la figure 2, apte à assurer une réflexion optimale vers les auditeurs. In side view, the ceiling has the apparent curved shape in particular in FIG. 2, capable of ensuring optimal reflection towards the listeners.

Conformément à l'invention, ce plafond 1 est constitué d'un grand nombre de boudins gonflables 7 qui sont placés côte à côte et chacun selon un axe 8 qui est orthogonal à l'axe de propagation sonore 5. Ces boudins 7 sont bien entendu placés de façon que leur plan transversal médian soit confondu avec le plan vertical passant par l'axe 5. According to the invention, this ceiling 1 consists of a large number of inflatable tubes 7 which are placed side by side and each along an axis 8 which is orthogonal to the axis of sound propagation 5. These tubes 7 are of course placed so that their median transverse plane coincides with the vertical plane passing through axis 5.

Chaque boudin 7 est en une matière plastique ignifugée, du genre PVC. Il est suspendu, au moyen de fils amovibles 9 passant dans des oeillets 10, à un tube métallique ovalisé 11 qui lui est parallèle. Each tube 7 is made of a flame-retardant plastic material, of the PVC type. It is suspended, by means of removable wires 9 passing through eyelets 10, from an ovalized metal tube 11 which is parallel to it.

L'ensemble des tubes 11 est soudé sur des tubes cintrés 12, qui sont orthogonaux à l'axe 8 et qui confèrent au plafond 1 la forme cintrée souhaitée.All of the tubes 11 are welded onto curved tubes 12 which are orthogonal to the axis 8 and which give the ceiling 1 the desired curved shape.

Les cinq plus grands tubes 12 sont assemblés au moyen d'une ossature tubulaire 13 qui est formée d'un cadre carré 17 composé de quatre poutres 14 et servant de support à des bras en porte-à-faux 18, qui sont chacun articulés en 19 sur ce cadre 17 de manière réglable en hauteur par des moyens classiques non représentés. Ce cadre 17 est suspendu en bout des câbles 2 à 4 précités par l'intermédiaire de treuils électriques 15,16 aptes à régler l'inclinaison du plafond 1. The five largest tubes 12 are assembled by means of a tubular frame 13 which is formed by a square frame 17 composed of four beams 14 and serving to support cantilever arms 18, which are each articulated in 19 on this frame 17 in an adjustable manner in height by conventional means not shown. This frame 17 is suspended at the end of the above cables 2 to 4 by means of electric winches 15, 16 able to adjust the inclination of the ceiling 1.

Les boudins gonflables 7 assurent une réflexion optimale des sons sans transmission partielle de ceux-ci à travers le plafond 1, l'air restant le meilleur absorbant connu à ce jour. La structure I est légère, aisément démontable et transportable. The inflatable tubes 7 ensure optimal reflection of the sounds without partial transmission of these through the ceiling 1, the air remaining the best absorbent known to date. Structure I is light, easily removable and transportable.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit. Le plafond pourrait par exemple avoir d'autres formes, et être assemblé, fixé, et suspendu par d'autres moyens.  Of course, the invention is not limited to the embodiment which has just been described. The ceiling could for example have other shapes, and be assembled, fixed, and suspended by other means.
