Description

La présente invention concerne un dispositif de projection de matériaux légers tels que des confettis ou analogues et/ou des émulsions du type air dans phase aqueuse telle que de la mouse, de la neige de théâtre, des bulles ou similaires.The present invention relates to a device for spraying lightweight materials such as confetti or the like and / or air-like emulsions in aqueous phase such as mouse, theater snow, bubbles or the like.

Dans le domaine des effets scéniques et plus généralement dans le domaine du spectacle, on connaît bien des dispositifs de projection de matériaux légers tels que des confettis par exemple ou de neige dite de théâtre comprenant un réservoir dans lequel sont contenus les confettis ou la neige de théâtre connecté à des moyens de projection des confettis ou de la neige consistant dans un transvecteur amplificateur d'air alimenté par de l'air comprimé procuré par une bouteille d'air comprimé munie d'un détendeur.In the field of scenic effects and more generally in the field of entertainment, light projection devices such as confetti for example or so-called theater snow are known, including a reservoir in which confetti or snow is contained. theater connected to confetti or snow throwing means consisting of an air-amplifying transvector powered by compressed air provided by a compressed air cylinder provided with a pressure reducer.

C'est le cas, par exemple, du brevet américain US 6.149.495 décrivant un dispositif de projection de confettis et de neige de théâtre. Le dispositif de projection de confettis et de neige de théâtre comprend deux compartiments, un premier compartiment accueillant un dispositif de mise sous vide et un orifice d'aspiration en communication avec un second compartiment et un orifice d'évacuation en communication avec l'extérieur du dispositif. Le second compartiment est rempli de confettis ou de neige de théâtre. Ainsi, seuls les matériaux qui sont aptes à être déplacés par de l'air sont susceptibles d'entrer dans le dispositif de mise sous vide et peuvent être expulsés à travers le dispositif de mise sous vide.This is the case, for example, of US Pat. No. 6,149,495 describing a device for confetti projection and theater snow. The confetti and theater snow thrower comprises two compartments, a first compartment accommodating a vacuum device and a suction port in communication with a second compartment and an evacuation port in communication with the outside of the chamber. device. The second compartment is filled with confetti or theater snow. Thus, only materials that are able to be moved by air are likely to enter the evacuation device and can be expelled through the evacuation device.

Ce type de dispositif présente l'inconvénient de procurer un rayon d'éjection des confettis ou de la neige particulièrement faible. De plus, pour la projection de neige de théâtre, il convient de produire préalablement ladite neige par un dispositif adapté puis d'introduire la neige ainsi produite dans le second compartiment du dispositif de distribution qui rend l'opération particulièrement longue et délicate.This type of device has the disadvantage of providing a confetti ejection radius or particularly low snow. In addition, for the projection of snow theater, it is necessary to previously produce said snow by a suitable device and then to introduce the snow thus produced in the second compartment of the dispensing device which makes the operation particularly long and delicate.

On connaît par ailleurs, un système de projection de matériaux légers tels que des confettis décrit par le brevet américain US 6.364.737. Ce brevet constitue la base du préambule de la revendication 1. Ce système de projection de matériaux légers comprend un boîtier de stockage pour stocker des matériaux légers tels que les confettis et à son extrémité supérieure un transvecteur a amplificateur d'air alimenté par de l'air comprimé distribué par une bouteille d'air comprimé munie d'un détendeur et d'une vanne, un membre d'éjection de forme globalement tronconique étant connecté au transvecteur pour guider le flux d'air produit par le transvecteur qui propulse les confettis. Accessoirement, la paroi supérieure du boîtier est articulée audit boîtier afin de permettre différentes inclinaisons du membre d'éjection.Also known is a projection system of lightweight materials such as confetti described by US Patent 6,364,737. This patent forms the basis of the preamble of claim 1. This light material projection system comprises a storage box for storing lightweight materials such as confetti and at its upper end an air-fed amplifier transvector. compressed air distributed by a compressed air cylinder provided with a pressure reducer and a valve, a generally frustoconical ejection member being connected to the transvector for guiding the air flow produced by the transvector which propels the confetti. Incidentally, the upper wall of the housing is hinged to said housing to allow different inclinations of the ejection member.

Ce type de dispositif présente l'inconvénient de nécessiter pour chaque système de projection d'une bouteille d'air comprimé qui est pilotée par un opérateur actionnant la vanne, rendant quasiment impossible la réalisation d'effets visuels tels que des vagues de neige ou de confettis.This type of device has the disadvantage of requiring for each projection system a bottle of compressed air which is controlled by an operator operating the valve, making it almost impossible to achieve visual effects such as snow or snow waves. confetti.

L'un des buts de l'invention est donc de remédier à tous ces inconvénients en proposant un dispositif de projections de matériaux légers tels que des confettis ou analogues et/ou des émulsions du type air dans phase aqueuse telles que de la mousse, de la neige de théâtre, des bulles ou similaires, de conception simple et peu onéreuse et permettant de réaliser des effets visuels tels que des vagues ou similaire.One of the aims of the invention is therefore to remedy all these drawbacks by proposing a device for spraying light materials such as confetti or the like and / or emulsions of the air type in aqueous phase such as foam, theater snow, bubbles or the like, of simple and inexpensive design and allowing for visual effects such as waves or the like.

A cet effet, et conformément à l'invention, il est proposé un dispositif de projection de matériaux légers tels que des confettis ou analogues et/ou des émulsions du type air dans phase aqueuse telles que de la mousse, de la neige de théâtre, des bulles ou similaires, comprenant un réservoir comprenant les matériaux légers ou une phase aqueuse et relié par des moyens de raccordement à un dispositif de mise sous vide tel qu'un transvecteur amplificateur d'air, par exemple, alimenté en air comprimé par des bouteilles d'air comprimé munies d'un détendeur, le réservoir contenant les matériaux légers étant raccordé à l'extrémité arrière du transvecteur où s'exerce une dépression, une forte surpression s'exerçant à l'extrémité avant opposée dudit transvecteur sur laquelle est connectée un élément tubulaire, de préférence tronconique, s'évasant depuis le transvecteur vers l'extérieur, pour guider le flux d'air produit par ledit tranvecteur, afin de projeter dans les airs les matériaux légers ; ledit dispositif est remarquable en ce qu'il comprend un élément de distribution de l'air comprimé comprenant au moins une entrée connectée à la sortie du détendeur et au moins deux sorties, une première sortie connectée à l'entrée d'air comprimé du transvecteur amplificateur d'air et une seconde sortie dite à obturation automatique, c'est-à-dire une sortie qui est obturée, par exemple, par une bille formant clapet lorsque aucun moyen de raccordement n'est connecté à ladite sortie et qui est ouverte lorsqu'un moyen de raccordement y est connecté, apte a être accordé à l'entrée d'un élément de distribution d'un second dispositif de projection de matériaux légers.For this purpose, and in accordance with the invention, there is provided a device for spraying light materials such as confetti or the like and / or air-like emulsions in aqueous phase such as foam, theater snow, bubbles or the like, comprising a reservoir comprising the light materials or an aqueous phase and connected by means of connection to a vacuum device such as an air amplifier transvector, for example, supplied with compressed air by bottles of compressed air equipped with a pressure reducer, the tank containing the light materials being connected to the rear end of the transvector where a depression is exerted, a strong overpressure exerted on the opposite front end of said transvector to which is connected a tubular element, preferably frustoconical, flaring from the transvector outwards, for guiding the flow of air produced by said tranvecteur, in order to project the light materials into the air; said device is remarkable in that it comprises a compressed air distribution element comprising at least one input connected to the output of the expander and at least two outputs, a first output connected to the compressed air inlet of the transvector an air amplifier and a second so-called automatic shut-off outlet, that is to say an outlet which is closed, for example, by a ball forming a valve when no connection means is connected to said outlet and which is open when a connection means is connected thereto, adapted to be tuned to the input of a distribution element of a second light material projection device.

On comprend bien que, contrairement aux dispositifs de l'art antérieur, une unique source d'alimentation en air comprimé tel qu'une ou plusieurs bouteilles d'air comprimé alimentent plusieurs dispositifs de projection de matériaux légers raccordés en série permettant ainsi de réaliser des effets visuels tels que des vagues ou analogues.It is well understood that, unlike the devices of the prior art, a single source of compressed air supply such as one or more compressed air bottles feed several light material projection devices connected in series thus making it possible to perform visual effects such as waves or the like.

En référence à la figure 3, l'embase 6 constituée d'un corps creux cylindrique comprend trois pieds 12 uniformément répartis autour de l'embase 6 et solidarisée à sa paroi latérale. L'embase 6 comprend, par ailleurs, un élément de distribution de l'air comprimé 13 positionné à l'intérieur de ladite embase 6 et comprenant une entrée 14 connectée à la sortie d'une unité d'alimentation en air comprimé 15 que l'on détaillera plus loin et trois sorties 16, 17 et 18. Les sorties 16, 17 et 18 de l'élément de distribution de l'air comprimé 13 consistent dans une première sortie 16 connectée à l'entrée d'air comprimé du transvecteur amplificateur 3, d'une seconde sortie 17 dite à obturation automatique, c'est-à-dire une sortie qui est obturée par exemple par une bille formant clapet lorsque aucun moyen de raccordement n'est connecté à ladite sortie et qui est ouverte lorsqu'un moyen de raccordement y est connecté, apte à être raccordée à l'entrée d'un élément de distribution d'un second dispositif de projection de matériaux légers, et une troisième sortie 18 connectée par des moyens de raccordement à un réservoir de matériaux légers et/ou à des moyens de distribution de la phase aqueuse positionnés dans le flux d'air projeté par le transvecteur amplificateur d'air 3 comme il sera détaillé ci-après. L'élément de distribution de l'air comprimé 13 est solidarisé à l'intérieur de l'embase 6 de telle sorte que l'entrée 14 apte à être connectée à une unité d'alimentation en air comprimé 15 et la seconde sortie 17 apte à être connectée à l'entrée d'un élément de distribution d'un second dispositif de projection de matériaux légers fasse saillie de la paroi latérale de l'embase 6.Referring to Figure 3, the base 6 consists of a cylindrical hollow body comprises three legs 12 uniformly distributed around the base 6 and secured to its side wall. The base 6 furthermore comprises a compressed air distribution element 13 positioned inside said base 6 and comprising an inlet 14 connected to the outlet of a compressed air supply unit 15 which the three further outlets 16, 17 and 18 will be detailed later. Outlets 16, 17 and 18 of the compressed air distribution element 13 consist of a first outlet 16 connected to the compressed air inlet of the transvector amplifier 3, a second output 17 said automatic shutter, that is to say an outlet which is closed for example by a ball valve when no connection means is connected to said output and which is open when a connection means is connected thereto, adapted to be connected to the input of a distribution element of a second light material projection device, and a third outlet 18 connected by connecting means to a material reservoir light and / or distribution means of the aqueous phase positioned in the air flow projected by the air amplifier transvector 3 as will be detailed below. The compressed air distribution element 13 is secured inside the base 6 in such a way that that the inlet 14 adapted to be connected to a compressed air supply unit 15 and the second outlet 17 adapted to be connected to the input of a distribution element of a second device for projecting light materials protrudes of the side wall of the base 6.

En référence aux figures 1 à 3, la première sortie 16 de l'élément de distribution de l'air comprimé 13 s'étendant à l'intérieur de l'embase 6 est connectée par des premiers moyens de raccordement 19 qui font saillie de la face supérieure de l'embase 6 par un trou 20 pratiqué sur ladite face supérieure de l'embase 6 qui passe à travers les branches 4a, 4b de l'étrier 4 et à travers un trou 21 pratiqué dans le capot thermoformé 11 solidaire du carter 1, à l'entrée d'air comprimé 22 du transvecteur amplificateur d'air 3. Le premier moyen de raccordement 19 connectant la première sortie 16 de l'élément de distribution d'air comprimé 13 à l'entrée d'air comprimé 22 du transvecteur 3 comprend une électrovanne 23 consistant avantageusement dans une électrovanne dite proportionnelle apte à faire varier le débit d'air comprimé transmis au transvecteur amplificateur 3, le débit de ce dernier étant proportionnel au débit d'air comprimé alimentant ledit transvecteur 3, positionnée à l'intérieur de l'embase 6 et pilotée par des moyens de commande 24. Ces moyens de commande 24 sont avantageusement connectés à un récepteur 25 apte à recevoir les informations d'un boîtier de commande 26 comportant au moins un potentiomètre 27 et un émetteur 28. Ainsi, un opérateur en actionnant le potentiomètre 27 du boîtier de commande 26 peut piloter l'électrovanne 23 afin de faire varier le débit d'air comprimé alimentant le transvecteur amplificateur 3 faisant ainsi varier le débit du flux d'air projeté par ledit transvecteur 3.With reference to FIGS. 1 to 3, the first outlet 16 of the compressed air distribution element 13 extending inside the base 6 is connected by first connection means 19 which project from the upper face of the base 6 through a hole 20 carried out on said upper face of the base 6 which passes through the branches 4a, 4b of the yoke 4 and through a hole 21 formed in the cover 11 integral thermoformed of the casing 1, to the compressed air inlet 22 of the air amplifier transvector 3. The first connection means 19 connecting the first outlet 16 of the compressed air distribution element 13 to the air inlet compressed 22 of the transvector 3 comprises a solenoid valve 23 advantageously consisting in a so-called proportional solenoid valve capable of varying the flow of compressed air transmitted to the amplifier transvector 3, the flow rate of the latter being proportional to the flow rate of compressed air supplying said tr 3 years, positioned inside the base 6 and controlled by control means 24. These control means 24 are preferably connected to a receiver 25 adapted to receive the information of a control unit 26 having at least one potentiometer 27 and a transmitter 28. Thus, an operator by operating the potentiometer 27 of the control box 26 can drive the solenoid valve 23 to vary the flow of compressed air supplying the amplifier transvector 3 thus varying the flow rate of the flow of air projected by said transvector 3.

En référence aux figures 3 et 6, la seconde sortie 17 de l'élément de distribution d'air comprimé 13 qui fait saillie de la paroi latérale de l'embase 6 à côté de l'entrée 14 dudit élément de distribution d'air comprimé 13 est apte à être connectée par des seconds moyens de raccordement 29 à l'entrée 14' d'un élément de distribution 13' d'un second dispositif de projection de matériaux légers conforme à l'invention. On observera que plusieurs dispositifs peuvent ainsi être connectés en série et alimentés par une unité d'alimentation en air comprimé 15.Referring to Figures 3 and 6, the second outlet 17 of the compressed air delivery member 13 protrudes from the side wall of the base 6 adjacent the inlet 14 of said compressed air distribution member 13 is capable of being connected by second connection means 29 to the input 14 'of a distribution element 13' of a second light material projection device according to the invention. It will be observed that several devices can thus be connected in series and powered by a compressed air supply unit 15.

En référence aux figures 1 à 3, la troisième sortie 18 de l'élément de distribution d'air comprimé 13 s'étendant à l'intérieur de l'embase 6 est connectée par des troisièmes moyens de raccordement 30 qui font saillie de l'embase 6 par un second trou 31 pratiqué sur la face supérieure de ladite embase 6 à des moyens de distribution 32 (figures 1 et 2) de la phase aqueuse positionnés dans le flux d'air projeté par le transvecteur à amplificateur d'air 3. Ces moyens de distribution 32, en références aux figures 1 et 2, consistent dans un second transvecteur amplificateur d'air 33 solidarisé à l'élément d'éjection 7 en débouchant radialement à l'intérieur dudit élément d'éjection tubulaire 7 à proximité de son extrémité libre, ledit second transvecteur 33 comprenant un tube capillaire 34 connecté par un tuyau 35 à un réservoir 36 contenant la phase aqueuse et s'étendant à l'intérieur du corps cylindrique du second transvecteur 33.With reference to FIGS. 1 to 3, the third outlet 18 of the compressed air distribution element 13 extending inside the base 6 is connected by third connection means 30 which project from the base 6 by a second hole 31 formed on the upper face of said base 6 to distribution means 32 (FIGS. 1 and 2) of the aqueous phase positioned in the flow of air projected by the air-amplifier transvector 3. These distribution means 32, with reference to FIGS. 1 and 2, consist of a second air amplifier transvector 33 secured to the ejection element 7 and opening radially inside said tubular ejection element 7 in the vicinity of its free end, said second transvector 33 comprising a capillary tube 34 connected by a pipe 35 to a reservoir 36 containing the aqueous phase and extending inside the cylindrical body of the second transvector 33.

En référence à la figure 7, le tube capillaire 34 s'étend à l'intérieur du corps globalement cylindrique du second transvecteur 33 en formant un angle α d'environ 45° par rapport à l'axe longitudinal A du corps cylindrique du transvecteur 33 de telle sorte que l'extrémité libre dudit tube capillaire 34 se situe sur l'axe longitudinal du corps cylindrique du transvecteur 33 dans la partie avant 33a où se crée une forte surpression, la partie arrière 33b du transvecteur 33 étant le siège d'une dépression, lorsque le corps cylindrique du transvecteur est alimenté en air comprimé. Ainsi, le flux d'air créé dans la partie avant du corps cylindrique du tranvecteur 33 crée une dépression à l'entrée du tube capillaire 34 qui aspire la phase aqueuse contenue dans le réservoir 36 connecté au tube capillaire 34 par le tuyau 35.With reference to FIG. 7, the capillary tube 34 extends inside the generally cylindrical body of the second transvector 33 at an angle α of approximately 45 ° with respect to the longitudinal axis A of the cylindrical body of the transvector 33 such that the free end of said capillary tube 34 is located on the longitudinal axis of the cylindrical body of the transvector 33 in the front portion 33 a which creates a high pressure, the rear part 33 b of the transvector 33 being the seat a depression, when the cylindrical body of the transvector is supplied with compressed air. Thus, the air flow created in the front portion of the cylindrical body of the tranvector 33 creates a vacuum at the inlet of the capillary tube 34 which sucks the aqueous phase contained in the tank 36 connected to the tube capillary 34 through the pipe 35.

Il va de soi que le réservoir 36 peut comprendre des moyens pour créer une surpression à l'intérieur dudit réservoir 36 afin de faciliter et de réguler le débit de la phase aqueuse s'écoulant du tube capillaire 34.It goes without saying that the reservoir 36 may comprise means for creating an overpressure inside said reservoir 36 in order to facilitate and regulate the flow rate of the aqueous phase flowing from the capillary tube 34.

Par ailleurs, en référence aux figures 1 et 2, les moyens de distribution 32 de la phase aqueuse comprennent un manchon 37 obtenu dans un matériau souple ou semi-rigide perméable dont les extrémités libres sont respectivement solidaires de la partie avant 33a du second transvecteur 33, c'est-à-dire solidaire du corps creux cylindrique débouchant radialement dans l'élément d'éjection 7, et de la paroi interne de l'élément d'éjection tubulaire 7 diamétralement opposé à la paroi où débouche le transvecteur 33 de telle sorte que le manchon 37 s'étende diamétralement à l'intérieur de l'élément d'éjection tubulaire 7 à proximité de son extrémité libre. Ainsi, lorsque le premier et le second transvecteur 3 et respectivement 33 sont alimentés par de l'air comprimé, la phase aqueuse contenue dans le réservoir 36 est projetée dans le manchon 37 qui s'étend diamétralement à l'intérieur de l'élément d'éjection 7 dans lequel est canalisé un flux d'air généré par le premier transvecteur 3 formant ainsi à la sortie de l'élément d'éjection 7 une émulsion qui peut consister soit dans de la mousse, soit dans de la neige de théâtre, soit dans des bulles en fonction de la nature de la phase aqueuse contenue dans le réservoir 36.Furthermore, with reference to Figures 1 and 2, the dispensing means 32 of the aqueous phase comprises a sleeve 37 received in a flexible or semi-rigid permeable whose free ends are respectively integral with the front portion 33 a of the second transvector 33, that is to say integral with the cylindrical hollow body opening radially in the ejection element 7, and the inner wall of the tubular ejection element 7 diametrically opposite the wall where the transvector 33 opens such that the sleeve 37 extends diametrically inside the tubular ejection element 7 near its free end. Thus, when the first and the second transvector 3 and respectively 33 are powered by compressed air, the aqueous phase contained in the reservoir 36 is projected into the sleeve 37 which extends diametrically inside the element. ejection 7 in which is channeled a flow of air generated by the first transvector 3 thus forming at the outlet of the ejection element 7 an emulsion which can consist either in foam or in theater snow, either in bubbles depending on the nature of the aqueous phase contained in the reservoir 36.

Par ailleurs, en référence à la figure 3, les troisièmes moyens de raccordement 30 comprennent une seconde électrovanne 38 positionnée à l'intérieur de l'embase 6 entre la troisième sortie 18 de l'élément de distribution de l'air comprimé 13 et les moyens de distribution 32 de la phase aqueuse, ladite seconde électrovanne 38 étant pilotée par les moyens de commande 24.Furthermore, with reference to FIG. 3, the third connection means 30 comprise a second solenoid valve 38 positioned inside the base 6 between the third outlet 18 of the compressed air distribution element 13 and the distribution means 32 of the aqueous phase, said second solenoid valve 38 being controlled by the control means 24.

Selon une première variante d'exécution du dispositif de projection des matériaux légers conformes à l'invention, en référence à la figure 2, les troisièmes moyens de raccordement 30 raccordés à la troisième sortie de l'élément de distribution d'air comprimé 13 sont connectés non plus aux moyens de distribution de la phase aqueuse mais sur la paroi latérale d'un réservoir 40 des matériaux légers, tels que des confettis ou similaires, comprenant sur sa paroi supérieure une sortie 41 connectée par des moyens de raccordement flexibles à un tube coudé flexible 42 solidarisé à la partie arrière 3b du transvecteur 3, c'est-à-dire la partie du transvecteur 3 où se crée une forte dépression lorsque ledit transvecteur 3 est alimenté en air comprimé. Ainsi, lorsque le transvecteur 3 est alimenté en air comprimé, une forte dépression se crée dans le tube coudé flexible 42 aspirant ainsi les confettis contenus dans le réservoir 40 pour les projeter par l'élément d'éjection 7 qui a été remplacé avantageusement par un élément d'éjection 7 ne comprenant pas de manchon 37 s'étendant diamétralement à proximité de son extrémité libre afin d'éviter toute obstruction lors de l'éjection des confettis.According to a first alternative embodiment of the projection device of the light materials according to the invention, with reference to FIG. 2, the third connection means 30 connected to the third outlet of the compressed air distribution element 13 are no longer connected to the distribution means of the aqueous phase but to the side wall of a reservoir 40 light materials such as confetti or similar, comprising on its upper wall an outlet 41 connected by flexible connection means to a flexible pipe bend 42 integral with the rear part 3b of the transvector 3, that is, say the part of the transvector 3 where creates a strong depression when said transvector 3 is supplied with compressed air. Thus, when the transvector 3 is supplied with compressed air, a high vacuum is created in the flexible elbow tube 42 sucking the confetti contained in the reservoir 40 to project them by the ejection element 7 which has been advantageously replaced by a ejection element 7 not including sleeve 37 extending diametrically near its free end to prevent clogging during the ejection of confetti.

A cet égard, selon une variante d'exécution de l'élément d'éjection 7, en référence aux figures 4 et 5, ledit élément d'éjection 7 consiste dans un tube tronconique dit extérieur 7a comprenant à proximité de sa petite base solidarisée à l'extrémité avant du transvecteur 3 un second tube tronconique dit intérieur 7b coaxial au premier tube tronconique extérieur 7a, s'étendant à l'intérieur de ce dernier sur une longueur au moins inférieure à la moitié de la longueur du tube extérieur 7a, et de préférence sur une longueur égale au tiers de la longueur du tube extérieur 7a, et solidarisé au tube extérieur par des entretoises 43, ledit tube extérieur 7a comprenant sur sa périphérie sur une longueur correspondant à la longueur du tube tronconique intérieur 7b depuis sa petite base des trous 44 régulièrement espacés. De la même manière que précédemment, l'extrémité libre de l'élément d'éjection 7, à proximité de la petite base de ce dernier comprend une collerette 8 munie de trous 9 aptes à accueillir des boulons pour fixer ledit élément d'éjection 7 sur le carter 1 du dispositif.In this regard, according to an alternative embodiment of the ejection element 7, with reference to Figures 4 and 5, said ejector 7 consists of a frusto-conical tube 7 has said outer member comprising close to its small base secured at the front end of the transvector 3 a second frustoconical tube said inner 7b coaxial with the first frusto-conical outer tube 7a, extending inside the latter over a length at least less than half the outer tube of length 7a, and preferably over a third length of the length of the outer tube 7a, and fastened to the outer tube by spacers 43, said outer tube 7 is comprising on its periphery over a length corresponding to the length of the frustoconical tube interior 7b from its small base 44 regularly spaced holes. In the same manner as above, the free end of the ejection element 7, close to the small base of the latter comprises a flange 8 provided with holes 9 adapted to accommodate bolts for fixing said ejection element 7 on the casing 1 of the device.

En référence à la figure 6, l'unité d'alimentation en air comprimé consiste dans une ou plusieurs bouteilles 45, avantageusement montées sur un chariot non représenté sur les figures, connectées à une rampe 46 qui est raccordée à un détendeur 47 par un raccord 48 en T dont les branches sont respectivement munies d'une vanne 49a, 49b, 49c respectivement connectées à la rampe 46, à un compresseur 50 et au détendeur 47, un filtre à air 51 étant avantageusement positionné à la sortie du détendeur 47 afin d'éviter que des impuretés ne viennent endommager les transvecteurs 3 ou 33.Referring to Figure 6, the compressed air supply unit consists of one or more bottles 45, advantageously mounted on a carriage not shown in the figures, connected to a ramp 46 which is connected to a pressure regulator 47 by a coupling 48 T whose branches are respectively provided with a valve 49 a, 49 b, 49 c respectively connected to the ramp 46, a compressor 50 and expander 47, an air filter 51 is advantageously positioned at the outlet of the expander 47 to prevent impurities from damaging the transvectors 3 or 33.

Il va de soi que l'on pourra adapter la forme et les dimensions de l'élément d'éjection 7 du dispositif de projection de matériaux légers en fonction du type de matériaux que l'on souhaite projeter ainsi que de l'effet visuel recherché et que les exemples que l'on vient de donner ne sont que des illustrations particulières en aucun cas limitatives quant au domaine d'application de l'invention.Of course, it will be possible to adapt the shape and dimensions of the ejection element 7 of the light material projection device according to the type of material that is to be projected and the desired visual effect. and that the examples which have just been given are only particular illustrations which are in no way limiting as to the field of application of the invention.
