  • La collerette est préférentiellement flexible, de sorte qu'une pression d'actionnement appliquée sur le bouton poussoir entraine la déformation de ladite collerette et un déplacement de la tige vers l'élément de contrôle, lequel élément de contrôle est alors actionné par la portion active de ladite tige.
  • La collerette est préférentiellement flexible avec des propriétés élastiques de sorte que ladite collerette soit dans une position non déformée lorsqu'aucune pression d'actionnement n'est appliquée sur le bouton poussoir, la portion active de la tige étant distante de l'élément de contrôle lorsque ladite collerette est dans cette position non déformée.

Modes préférés de réalisation de l'invention.Preferred embodiments of the invention.

Le projecteur objet de l'invention est un dispositif d'éclairage autonome étanche à l'eau. Il peut être installé contre la paroi d'une piscine ou d'un bassin et/ou peut être utilisé comme lampe, en extérieur, par exemple par temps de pluie. Dans la suite de la description, on emploi de manière indifférente les termes de « projecteur», « dispositif d'éclairage », « éclairage » ou « lampe ». The projector which is the subject of the invention is an autonomous waterproof lighting device. It can be installed against the wall of a swimming pool or a pond and / or can be used as a lamp, outdoors, for example in rainy weather. In the remainder of the description, the terms “ projector ” , “ lighting device ” , “ lighting ” or “ lamp ” are used interchangeably .

En se rapportant au mode de réalisation des figures 1 à 4, le dispositif d'éclairage 1 comprend une coque 2 sur laquelle est fixée une optique 3.With reference to the embodiment of figures 1 to 4 , the lighting device 1 comprises a shell 2 on which is fixed an optic 3.

La coque 2 est préférentiellement une pièce monobloc rigide obtenue par usinage ou moulage plastique, par exemple en ABS ou en polycarbonate, éventuellement traité anti-UV. Son épaisseur peut par exemple varier de 2 mm à 6 mm. Vue de face (figure 1), la face avant 20 de la coque 2 a une forme sensiblement carrée ou rectangulaire, dont les côtés ont par exemple une longueur comprise entre 5 cm et 20 cm. Vue de profil (figure 2), la coque 2 est légèrement convexe, c'es-à-dire bombée vers l'avant.The shell 2 is preferably a rigid monobloc part obtained by machining or plastic molding, for example in ABS or polycarbonate, optionally treated against UV. Its thickness may for example vary from 2 mm to 6 mm. Front view ( figure 1 ), the front face 20 of the shell 2 has a shape substantially square or rectangular, the sides of which have for example a length of between 5 cm and 20 cm. Profile view ( figure 2 ), the shell 2 is slightly convex, that is to say convex towards the front.

La face arrière 21 de la coque 2 se prolonge par une portion tubulaire 22 centrée sur l'axe géométrique X du projecteur 1. Cette portion tubulaire 22 a par exemple une longueur comprise entre 0,5 cm et 10 cm et une section circulaire dont le diamètre externe est par exemple compris entre 2 cm et 10 cm et dont le diamètre interne est par exemple compris entre 1,5 cm et 9,5 cm. Son extrémité arrière est fermée par une paroi 220 de sorte qu'elle forme un manchon permettant de loger différents éléments constitutifs du projecteur 1. Le manchon 22 peut être rapporté sur la face arrière 21 de la coque 2. Pour simplifier la conception et limiter les problèmes d'étanchéité, le manchon 22 est toutefois préférentiellement intégré à la coque 2 et obtenu lors du moulage de cette dernière.The rear face 21 of the shell 2 is extended by a tubular portion 22 centered on the geometric axis X of the projector 1. This tubular portion 22 has for example a length of between 0.5 cm and 10 cm and a circular section of which the external diameter is for example between 2 cm and 10 cm and whose internal diameter is for example between 1.5 cm and 9.5 cm. Its rear end is closed by a wall 220 so that it forms a sleeve making it possible to accommodate various constituent elements of the projector 1. The sleeve 22 can be attached to the rear face 21 of the shell 2. To simplify the design and limit the costs. sealing problems, the sleeve 22 is however preferably integrated into the shell 2 and obtained during the molding of the latter.

L'optique 3 est fixée sur la face avant 20 de la coque 2, centrée sur l'axe géométrique X. Elle est avantageusement réalisée en verre ou en matière plastique translucide ou transparente. Elle a une forme convexe qui suit la courbure de la face avant 20 et peut intégrer des facettes permettant la diffusion homogène de la lumière et le mélange des couleurs, en particulier lorsque le projecteur 1 est immergé dans l'eau. Elle a préférentiellement une forme circulaire et son diamètre est par exemple compris entre 2 cm et 15 cm. L'optique 3 est fixée de manière étanche à l'eau au niveau d'une ouverture aménagée à cet effet sur la face avant 20 de la coque 2. Cette fixation est réalisée par vissage combiné à un ou plusieurs joints, par soudage ultrason, par collage, ou toute autre technique convenant à l'homme du métier.The lens 3 is fixed on the front face 20 of the shell 2, centered on the geometric axis X. It is advantageously made of glass or of translucent or transparent plastic. It has a convex shape which follows the curvature of the front face 20 and can integrate facets allowing the homogeneous diffusion of light and the mixing of colors, in particular when the projector 1 is immersed in water. It preferably has a circular shape and its diameter is for example between 2 cm and 15 cm. The optic 3 is fixed in a watertight manner at an opening made for this purpose on the front face 20 of the shell 2. This fixing is made by screwing combined with one or more joints, by ultrasonic welding, by gluing, or any other technique suitable for those skilled in the art.

Comme cela apparaît sur la figure 4, la coque 2 et l'optique 3 délimitent une chambre 4 qui est étanche à l'eau, laquelle chambre permet de loger des éléments constitutifs du projecteur 1 et notamment des sources lumineuse 5.As it appears on the figure 4 , the shell 2 and the lens 3 delimit a chamber 4 which is watertight, which chamber makes it possible to accommodate the constituent elements of the projector 1 and in particular the light sources 5.

Ces sources lumineuses 5 sont préférentiellement des diodes électroluminescentes (ou LED) classiques ou de puissances, montées sur un support 50 qui se présente sous la forme d'une plaque ou d'un circuit imprimé. Ce support 50 est fixé par collage, soudage, emboitage ou vissage sur les parois internes de la chambre 4. Les sources lumineuses 5 peuvent être monochromes ou polychromes. Les sources lumineuses 5 et/ou le support 50 sont agencés dans la chambre 4 de manière à ce que lesdites sources soient en vis-à-vis de l'optique 3.These light sources 5 are preferably conventional or high-power light-emitting diodes (or LEDs), mounted on a support 50 which is in the form of a plate or a printed circuit. This support 50 is fixed by gluing, welding, fitting or screwing on the internal walls of the chamber 4. The light sources 5 can be monochrome or polychrome. The light sources 5 and / or the support 50 are arranged in the chamber 4 so that said sources are facing the optics 3.

Les sources lumineuses 5 sont alimentées électriquement par un dispositif de batterie électrique 51. Ce dispositif consiste en une ou plusieurs batteries ou piles électriques ou photopiles, rechargeables ou pas, logées dans la chambre 4, et éventuellement fixées sur le support 50 et auxquelles les sources lumineuses 5 sont électriquement connectées. Pour des raisons d'encombrement et pour optimiser la compacité du projecteur 1, on utilise avantageusement une ou plusieurs piles boutons dont la mise en place dans la chambre 4 se fait depuis une ouverture refermable étanche (non représentée) qui est par exemple aménagée sur la paroi arrière 220 du manchon 22. Si les sources lumineuses 5 sont des LEDs, celles-ci fonctionnent généralement sous 12 V. Le dispositif de batterie électrique 51 est alors adapté pour fournir cette énergie.The light sources 5 are supplied electrically by an electric battery device 51. This device consists of one or more batteries or electric cells or solar cells, rechargeable or not, housed in the chamber 4, and possibly fixed on the support 50 and to which the sources lights 5 are electrically connected. For reasons of size and to optimize the compactness of the projector 1, one or more button cells are advantageously used, the installation of which in the chamber 4 is made from a sealed reclosable opening (not shown) which is for example arranged on the rear wall 220 of the sleeve 22. If the light sources 5 are LEDs, these generally operate at 12 V. The electric battery device 51 is then adapted to supply this energy.

L'éclairage des sources lumineuses 5 est préférentiellement commandé par l'intermédiaire d'un élément de contrôle 52. Ce dernier est logé dans la chambre 4, et préférentiellement fixé sur le support 50. Cet élément de contrôle 52 est actionné par le bouton poussoir 6 décrit plus avant dans la description.The lighting of the light sources 5 is preferably controlled by means of a control element 52. The latter is housed in the chamber 4, and preferably fixed on the support 50. This control element 52 is actuated by the push button. 6 described further in the description.

Pour simplifier la conception du projecteur 1, l'élément de contrôle 52 se présente avantageusement sous la forme d'un interrupteur dont l'actionnement permet d'allumer ou d'éteindre les sources lumineuses 5. Lorsqu'il est actionné, cet interrupteur permet notamment d'ouvrir ou de fermer le circuit électrique connectant les sources lumineuses 5 au dispositif de batterie électrique 51. A titre d'exemple, en appuyant une fois sur le bouton poussoir 6, les sources lumineuses 5 s'allument et en appuyant une seconde fois sur ledit bouton, lesdites sources s'éteignent.To simplify the design of the projector 1, the control element 52 is advantageously in the form of a switch, the actuation of which makes it possible to turn on or off the light sources 5. When it is actuated, this switch allows in particular to open or close the electrical circuit connecting the light sources 5 to the electric battery device 51. By way of example, by pressing once on the push button 6, the light sources 5 turn on and by pressing a second time on said button, said sources turn off .

Dans une variante de réalisation, l'élément de contrôle 52 se présente sous la forme d'un commutateur ou d'une unité de gestion électronique comprenant un ou plusieurs processeurs ou microprocesseurs, activée par le bouton poussoir 6. Cette unité de gestion électronique peut être programmée de manière à contrôler les sources lumineuses 5 pour produire des effets lumineux (par exemple un effet stroboscopique) éventuellement combinés à des jeux de lumières (par exemple des changements de couleurs). A titre d'exemple, en appuyant une première fois sur le bouton poussoir 6, les sources lumineuses 5 s'allument, en appuyant une deuxième fois sur ledit bouton, lesdites sources s'allument et s'éteignent par intermittence (effet stroboscopique) et en appuyant une troisième fois sur ledit bouton, lesdites sources s'éteignent. Egalement, et à titre d'exemple encore, en appuyant une première fois sur le bouton poussoir 6, les sources lumineuses 5 s'allument, en appuyant une seconde fois de manière prolongée sur ledit bouton, lesdites sources changent de couleur et en appuyant une troisième fois sur ledit bouton, lesdites sources s'éteignent.In an alternative embodiment, the control element 52 is in the form of a switch or an electronic management unit comprising one or more processors or microprocessors, activated by the push button 6. This electronic management unit can be programmed so as to control the light sources 5 to produce light effects (for example a stroboscopic effect) possibly combined with plays of lights (for example color changes). By way of example, by pressing the push button 6 a first time, the light sources 5 come on, by pressing the said button a second time, said sources light up and go off intermittently (stroboscopic effect) and by pressing a third time on said button, said sources are switched off. Also, and by way of example again, by pressing the push button 6 for the first time, the light sources 5 are switched on, by pressing and prolonging said button a second time, said sources change color and by pressing a second time. third time on said button, said sources turn off.

En se rapportant plus particulièrement aux figures 5 à 7, le bouton poussoir 6 est installé dans un aménagement 30 réalisé dans l'optique 3. Cet aménagement 30 est préférentiellement obtenu lors du moulage de l'optique 3. Il peut également être réalisé après le moulage de l'optique 3, par usinage par exemple. Pour simplifier la conception du projecteur 1, l'aménagement 30 a préférentiellement une forme générale cylindrique de section circulaire, dont le diamètre est par exemple compris entre 10 mm et 40 mm. Le bouton poussoir 6 et l'aménagement 30 sont alignés axialement sur l'axe géométrique X.With particular reference to figures 5 to 7 , the push button 6 is installed in an arrangement 30 made in the optic 3. This arrangement 30 is preferably obtained during the molding of the optic 3. It can also be produced after the molding of the optic 3, by machining by example. To simplify the design of the projector 1, the arrangement 30 preferably has a generally cylindrical shape with a circular section, the diameter of which is for example between 10 mm and 40 mm. The push button 6 and the arrangement 30 are aligned axially on the geometric axis X.

Le bouton poussoir 6 est préférentiellement une pièce monobloc réalisée dans un matériau souple étanche à l'eau, du type silicone ou caoutchouc. Il présente une portion proximale 60 qui se présente, sur les figures annexée, sous la forme d'un disque ou d'une pastille dont le diamètre est par exemple compris entre 5 mm et 20 mm et dont l'épaisseur est par exemple comprise entre 1 mm et 5 mm. Cette portion proximale 60 est située à l'extérieur de la chambre 4, et se situe sensiblement dans le prolongement de la surface extérieure de l'optique 3. C'est sur cette portion proximale 60 qu'un utilisateur exerce une pression d'actionnement pour contrôler l'éclairage des sources lumineuses 5.The push button 6 is preferably a single piece made of a flexible waterproof material, of the silicone or rubber type. It has a proximal portion 60 which is, in the appended figures, in the form of a disc or of a pellet, the diameter of which is for example between 5 mm and 20 mm and the thickness of which is for example between 1 mm and 5 mm. This proximal portion 60 is located outside the chamber 4, and is located substantially in the extension of the outer surface of the optic 3. It is on this proximal portion 60 that a user exerts an actuating pressure. to control the illumination of light sources 5.

La bordure de la portion proximale 60 est pourvue d'une collerette 61 qui est souple et étanche à l'eau. Cette collerette 61 s'étend le long de l'axe géométrique X, vers la chambre 4. Elle a préférentiellement une forme cylindrique de section circulaire. Son diamètre externe correspond au diamètre de la portion proximale 60 et son épaisseur est par exemple comprise entre 1 mm et 5 mm. Sa longueur est par exemple comprise entre 5 mm et 20 mm. Comme mentionné précédemment, la portion proximale 60 et la collerette 61 sont avantageusement réalisées dans le même matériau et forment une pièce monobloc. On peut toutefois envisager que la collerette 61 et la portion proximale 60 soient réalisées dans deux matériaux distincts, un matériau déformable (flexible, souple ou rigide) pour ladite collerette et un matériau non déformable, préférentiellement rigide (par exemple en PVC ou en acier) pour ladite portion proximale. Dans ce cas, la collerette 61 est rapportée sur la portion proximale 60 et fixée à cette dernière de manière étanche à l'eau, par exemple par collage ou soudage.The edge of the proximal portion 60 is provided with a collar 61 which is flexible and waterproof. This collar 61 extends along the geometric axis X, towards the chamber 4. It preferably has a cylindrical shape of circular section. Its external diameter corresponds to the diameter of the proximal portion 60 and its thickness is for example between 1 mm and 5 mm. Its length is for example between 5 mm and 20 mm. As mentioned previously, the proximal portion 60 and the collar 61 are advantageously made of the same material and form a single piece. It can however be envisaged that the collar 61 and the proximal portion 60 are made of two distinct materials, a deformable material (flexible, flexible or rigid) for said collar and a non-deformable material, preferably rigid (for example PVC or steel). for said proximal portion. In this case, the collar 61 is attached to the proximal portion 60 and fixed to the latter in a waterproof manner, for example by gluing or welding.

La collerette 61 est délimitée par une paroi latérale présentant une face externe 610 et une face interne 611. Sur les figures annexées, la paroi latérale de la collerette 61 est droite, parallèle à l'axe géométrique X.The collar 61 is delimited by a side wall having an outer face 610 and an inner face 611. In the appended figures, the side wall of the flange 61 is straight, parallel to the geometric axis X.

La périphérie de la bordure distale de la collerette 61, c'est-à-dire la bordure qui est la plus éloignée de la portion proximale 60, est pourvue d'un joint d'étanchéité à l'eau 62. Ce dernier se présente préférentiellement sous la forme d'un joint annulaire, d'une lèvre ou d'un bourrelet, qui fait saillie depuis la face externe 610, sur toute la circonférence de la collerette 61. Par souci de simplification, le joint 62 fait partie intégrante de la collerette 61 et est réalisé dans le même matériau que cette dernière. Le joint 62 a par exemple une épaisseur comprise entre 1 mm et 5 mm et une longueur comprise également entre 1 mm et 5 mm. Sa section peut être carrée, rectangulaire, ronde, etc.The periphery of the distal edge of the collar 61, that is to say the edge which is furthest from the proximal portion 60, is provided with a seal sealing 62. The latter is preferably in the form of an annular seal, a lip or a bead, which projects from the outer face 610, over the entire circumference of the collar 61 For the sake of simplicity, the seal 62 forms an integral part of the flange 61 and is made of the same material as the latter. The gasket 62 has for example a thickness between 1 mm and 5 mm and a length also between 1 mm and 5 mm. Its section can be square, rectangular, round, etc.

Sur les figures 5 à 7, l'aménagement 30 présente une paroi latérale 310 et une paroi - ou rebord - de fond 320 agencées de manière à ce que ledit aménagement est une section sensiblement en forme de U, dans le plan médian sagittal du projecteur 1, lequel plan inclus l'axe géométrique X. Sur les figures annexées, la paroi latérale 310 est droite, parallèle à l'axe géométrique X, et la paroi de fond 320 perpendiculaire à ladite paroi latérale. La hauteur de la paroi latérale 310 correspond à celle du bouton 6, mais peut être légèrement inférieure, par exemple de quelques millimètres de manière à ce que au repos (c'est-à-dire sans pression d'actionnement), la portion distale 60 dudit bouton dépasse la face externe de l'optique 3 (figure 5), ce qui est susceptible de faciliter l'actionnement dudit bouton.On the figures 5 to 7 , the arrangement 30 has a side wall 310 and a bottom wall - or flange - 320 arranged so that said arrangement is a substantially U-shaped section, in the sagittal median plane of the projector 1, which plane includes the 'geometric axis X. In the accompanying figures, the side wall 310 is straight, parallel to the geometric axis X, and the bottom wall 320 perpendicular to said side wall. The height of the side wall 310 corresponds to that of the button 6, but can be slightly less, for example by a few millimeters so that at rest (that is to say without actuation pressure), the distal portion 60 of said button protrudes from the outer face of optics 3 ( figure 5 ), which is likely to facilitate the actuation of said button.

L'aménagement 30 présente une gorge 321 dans laquelle s'engage le joint 62. Sur les figures 5 à 7, cette gorge 321 est réalisée dans la paroi de fond 320. Sa forme correspond à celle du joint 62 de sorte que le joint puisse être correctement installé dans ladite gorge. Ainsi, lorsque le joint 62 est installé dans la gorge 321, ladite gorge et ledit joint coopèrent pour former étanchéité à l'eau entre l'optique 3 et le bouton poussoir 6. La largeur de la gorge 321 peut être légèrement inférieure à celle du joint 62, par exemple de quelques millimètres ou dixièmes de millimètre, de sorte que ledit joint soit monté en force dans ladite gorge pour améliorer l'étanchéité.The arrangement 30 has a groove 321 in which the seal 62 engages. figures 5 to 7 , this groove 321 is made in the bottom wall 320. Its shape corresponds to that of the seal 62 so that the seal can be correctly installed in said groove. Thus, when the gasket 62 is installed in the groove 321, said groove and said gasket cooperate to form a watertight seal between the optic 3 and the push button 6. The width of the groove 321 may be slightly less than that of the seal 62, for example a few millimeters or tenths of a millimeter, so that said seal is force-fitted in said groove to improve the seal.

Un organe de maintien 7 est installé dans l'aménagement 30 de manière à bloquer en position le joint 62 dans la gorge 321. Et finalement, cet organe de maintien 7 permet de maintenir en position le bouton 6 dans l'aménagement 30. Il se présente avantageusement sous la forme d'une bague installée autour de la collerette 61, et de manière plus générale autour du bouton poussoir 6, laquelle bague est alignée axialement sur l'axe géométrique X. La bague 7 peut être réalisée dans un matériau souple du type silicone ou caoutchouc, ou dans un matériau rigide du type PVC ou acier inoxydable par exemple.A retaining member 7 is installed in the arrangement 30 so as to block the seal 62 in position in the groove 321. And finally, this retaining member 7 makes it possible to keep the button 6 in position in the arrangement 30. It is secured in position. advantageously present in the form of a ring installed around the collar 61, and more generally around the push button 6, which ring is axially aligned with the geometric axis X. The ring 7 can be made of a flexible material of the silicone or rubber type, or in a rigid material such as PVC or stainless steel, for example.

Sur les figures 5 à 7, la bague 7 présente une paroi latérale externe 70, une paroi latérale interne 71, une paroi transversale proximale 72 et une paroi transversale distale 73. La hauteur des parois latérales 70, 71 correspond à la profondeur de l'aménagement 30 et plus particulièrement à la hauteur de sa paroi latérale 310. La paroi latérale externe 70 a un diamètre ajusté au diamètre de la paroi latérale 310 de l'aménagement 30. Par « ajusté », on entend que le diamètre de la paroi latérale externe 70 est sensiblement égal au diamètre de la paroi latérale 310, et préférentiellement légèrement inférieur (par exemple de 0,5 mm à 2 mm) pour assurer une mise en place aisée de la bague 7 dans l'aménagement 30. De même, la paroi latérale interne 71 a un diamètre ajusté (préférentiellement légèrement inférieur de 0,5 mm à 2 mm) au diamètre de la paroi latérale externe 610 de la collerette 61 pour assurer une mise en place aisée de la bague 7 autour de ladite collerette.On the figures 5 to 7 , the ring 7 has an outer side wall 70, an inner side wall 71, a proximal transverse wall 72 and a distal transverse wall 73. The height of the side walls 70, 71 corresponds to the depth of the arrangement 30 and more particularly to the height of its side wall 310. The outer side wall 70 has a diameter adjusted to the diameter of the side wall 310 of the arrangement 30. By " adjusted " is meant that the diameter of the outer side wall 70 is substantially equal to diameter of the side wall 310, and preferably slightly less (for example from 0.5 mm to 2 mm) to ensure easy positioning of the ring 7 in the arrangement 30. Likewise, the internal side wall 71 has a adjusted diameter (preferably slightly less than 0.5 mm to 2 mm) to the diameter of the outer side wall 610 of the collar 61 to ensure easy positioning of the ring 7 around said collar.

Dans le cas où le joint 62 dépasse de la gorge 321 (sa hauteur étant supérieure à la profondeur de ladite gorge), la bague 7, et plus particulièrement sa paroi transversale distale 73, vient écraser ledit joint lorsque ladite bague est installée dans l'aménagement 30. Cet écrasement assure une compression du joint 62 dans la gorge 321, et de ce fait une étanchéité optimale.In the event that the seal 62 protrudes from the groove 321 (its height being greater than the depth of said groove), the ring 7, and more particularly its distal transverse wall 73, crushes said seal when said ring is installed in it. arrangement 30. This crushing ensures compression of the seal 62 in the groove 321, and therefore optimum sealing.

La bague 7 est correctement installée dans l'aménagement 30, lorsque la paroi transversale distale 73 est en contact de la paroi de fond 320. Pour maintenir en position la bague 7 dans l'aménagement 30, la paroi latérale externe 70 peut être solidarisée par emboitage, soudage ou collage à la paroi latérale 310. Dans une variante de réalisation, la paroi latérale externe 70 peut présenter un filetage qui s'engage dans un filetage complémentaire réalisé sur la paroi latérale 310 de l'aménagement 30. Dans une autre variante de réalisation, c'est la paroi transversale distale 73 qui est solidarisée, par exemple par emboitage soudage ou collage, à la paroi de fond 320 de l'aménagement 30. Etant donné que l'étanchéité à l'eau du bouchon 6 est assurée par la coopération du joint 62 et de la gorge 321, il n'est pas nécessaire de prévoir une étanchéité supplémentaire entre la bague 7 et l'aménagement 30.Ring 7 is properly seated in arrangement 30, when distal transverse wall 73 contacts bottom wall 320. To hold in position the ring 7 in the arrangement 30, the outer side wall 70 can be secured by fitting, welding or gluing to the side wall 310. In an alternative embodiment, the outer side wall 70 may have a thread which engages in a complementary thread made on the side wall 310 of the arrangement 30. In another variant embodiment, it is the distal transverse wall 73 which is secured, for example by fitting, welding or gluing, to the bottom wall 320 of arrangement 30. Since the water-tightness of the stopper 6 is ensured by the cooperation of the seal 62 and the groove 321, it is not necessary to provide an additional seal between the ring 7 and the layout 30.

Sur les figures 5 à 7, le bouton poussoir 6 est pourvu d'une portion longitudinale 63 en forme de tige qui s'étend à l'intérieur de la chambre étanche 4, vers l'élément de contrôle 52. Cette tige 63 est coaxiale à l'axe géométrique X. Elle peut être cylindrique à section circulaire. A titre d'exemple, son diamètre est compris entre 1 mm et 10 mm et sa longueur comprise entre 5 mm et 30 mm. Pour simplifier la conception, du bouton 6, la tige 63 est avantageusement réalisée dans le même matériau que la portion proximale 60 et la collerette 61 et forme avec ces dernières une pièce monobloc. On peut toutefois envisager que la tige 63 soit rapportée sur la portion proximale 60 et fixée à cette dernière par emboitage, vissage, collage ou soudage. On peut également prévoir que la tige 63 soit réalisée dans un matériau plus rigide que celui de la collerette 61, par exemple en PVC ou en acier inoxydable de manière à limiter sa déformation lorsqu'elle active l'élément de contrôle 52.On the figures 5 to 7 , the push button 6 is provided with a longitudinal portion 63 in the form of a rod which extends inside the sealed chamber 4, towards the control element 52. This rod 63 is coaxial with the geometric axis X It can be cylindrical with a circular section. By way of example, its diameter is between 1 mm and 10 mm and its length between 5 mm and 30 mm. To simplify the design of the button 6, the rod 63 is advantageously made of the same material as the proximal portion 60 and the flange 61 and forms with the latter a single piece. However, it is conceivable that the rod 63 is attached to the proximal portion 60 and fixed to the latter by fitting, screwing, gluing or welding. Provision can also be made for the rod 63 to be made of a material more rigid than that of the collar 61, for example of PVC or of stainless steel so as to limit its deformation when it activates the control element 52.

L'aménagement 30 présente avantageusement un guide 322 dans lequel la tige 63 est montée glissant. Sur les figures 5 à 7, ce guide 321 se présente sous la forme d'un conduit tubulaire à l'intérieur duquel passe la tige 63. Ce conduit tubulaire est coaxial à l'axe géométrique X et s'étend dans la chambre 4 sur une longueur par exemple comprise entre 2 mm et 20 mm.The arrangement 30 advantageously has a guide 322 in which the rod 63 is slidably mounted. On the figures 5 to 7 , this guide 321 is in the form of a tubular duct inside which the rod 63 passes. This tubular duct is coaxial with the geometric axis X and extends in the chamber 4 over a length for example between 2 mm and 20 mm.

La tige 63 présente une portion active 64 qui fait office d'actionneur de l'élément de contrôle 52. Cette portion active 64 peut faire partie intégrante de la tige 63, ou être rapportée sur l'extrémité distale 630 de ladite tige, par exemple par emboitage, soudage, collage ou vissage. Une portion active 64 rapportée offre l'avantage de pouvoir utiliser un matériau différent de celui de la tige 63, et de manière plus générale de celui de la portion proximale 60 et de la collerette 61. En outre, une portion active 64 rapportée facilite le montage du bouton poussoir 6 et notamment le passage de la tige 63 au travers du guide 322.The rod 63 has an active portion 64 which acts as an actuator for the control element 52. This active portion 64 may be an integral part of the rod 63, or be attached to the distal end 630 of said rod, for example. by fitting, welding, gluing or screwing. An attached active portion 64 offers the advantage of being able to use a material different from that of the rod 63, and more generally from that of the proximal portion 60 and of the collar 61. In addition, an attached active portion 64 facilitates the fitting. mounting of the push button 6 and in particular the passage of the rod 63 through the guide 322.

Sur les figures 5 à 7, cette portion active 64 se présente sous la forme d'une tige dont le diamètre correspond à celui de la tige 63 et dont la longueur peut être comprise entre 5 mm et 10 mm. La portion active 64 présente une extrémité proximale 640 qui se solidarise sur l'extrémité distale 630 de la tige 63. La portion active 64 présente également une extrémité distale 641 qui est opposée à l'extrémité proximale 640 et qui forme une surface active, par exemple de forme évasée. Cette surface active 641 est adaptée pour coopérer avec une surface active 520 de l'élément de contrôle 52 avec laquelle elle est en vis-à-vis. Les surfaces actives 641 et 520 sont préférentiellement alignées sur l'axe géométrique X. Sur la figure 5, lorsque le bouton 6 est au repos (aucune pression d'actionnement n'étant appliquée sur ledit bouton), les surfaces actives 641 et 520 sont distantes l'une de l'autre. En se rapportant à la figure 7, lorsqu'une pression d'actionnement est appliquée sur le bouton 6, par exemple suite à l'appui sur ledit bouton par un doigt D de l'utilisateur, la tige 63 se déplace à l'intérieur de la chambre 4, vers l'élément de contrôle 52. Ce déplacement est schématisé par la flèche sur la figure 7 et consiste en une translation le long de l'axe géométrique X. La surface active 641 rentre alors en contact, ou se rapproche, de la surface active 520 provoquant l'activation de l'élément de contrôle 52.On the figures 5 to 7 , this active portion 64 is in the form of a rod whose diameter corresponds to that of the rod 63 and whose length can be between 5 mm and 10 mm. The active portion 64 has a proximal end 640 which is secured to the distal end 630 of the rod 63. The active portion 64 also has a distal end 641 which is opposite the proximal end 640 and which forms an active surface, by example of a flared shape. This active surface 641 is adapted to cooperate with an active surface 520 of the control element 52 with which it is vis-à-vis. The active surfaces 641 and 520 are preferably aligned on the geometric axis X. On the figure 5 , when the button 6 is at rest (no actuation pressure being applied to said button), the active surfaces 641 and 520 are distant from one another. By referring to the figure 7 , when an actuation pressure is applied to the button 6, for example following the pressing on said button by a finger D of the user, the rod 63 moves inside the chamber 4, towards the control element 52. This movement is shown diagrammatically by the arrow on the figure 7 and consists of a translation along the geometric axis X. The active surface 641 then comes into contact with, or approaches, the active surface 520 causing the activation of the control element 52.

Les surfaces actives 641 et 520 peuvent coopérer mécaniquement dans le cas où l'élément de contrôle 52 est du type interrupteur mécanique sensible à la pression. Dans ce cas, suite à une pression d'actionnement appliquée sur le bouton 6, la surface active 641 rentre en contact avec la surface active 520 et la pousse jusqu'à activer l'élément de contrôle 52.The active surfaces 641 and 520 can cooperate mechanically in the case where the control element 52 is of the pressure sensitive mechanical switch type. In this case, following an actuation pressure applied to the button 6, the active surface 641 comes into contact with the active surface 520 and pushes it until the control element 52 is activated.

Les surfaces actives 641 et 520 peuvent également coopérer magnétiquement dans le cas où l'élément de contrôle 52 est du type interrupteur/commutateur/unité de gestion électronique sensible à un champ magnétique. Dans ce cas, la surface active 641 est réalisée dans un matériau magnétique, par exemple un aimant, adapté pour modifier un champ magnétique généré au niveau de la surface active 520, par un composant intégré dans l'élément de contrôle 52, par exemple une bobine. Suite à une pression d'actionnement appliquée sur le bouton 6, il n'est pas nécessaire que la surface active 641 rentre en contact avec la surface active 520. Un simple rapprochement de ces deux surfaces permet de modifier le champ magnétique, laquelle modification entraîne l'activation de l'élément de contrôle 52.The active surfaces 641 and 520 can also cooperate magnetically in the case where the control element 52 is of the switch / switch / electronic management unit type sensitive to a magnetic field. In this case, the active surface 641 is made of a magnetic material, for example a magnet, adapted to modify a magnetic field generated at the level of the active surface 520, by a component integrated in the control element 52, for example a coil. Following an actuation pressure applied to the button 6, it is not necessary for the active surface 641 to come into contact with the active surface 520. A simple bringing together of these two surfaces makes it possible to modify the magnetic field, which modification entails activation of the control element 52.

En se rapportant à la figure 7, la flexibilité de la collerette 61 lui permet de se déformer lorsqu'une pression d'actionnement est appliquée sur le bouton 6. En pratique, la paroi latérale de la collerette 61 se déforme à l'intérieur de la bague 7 pour permettre l'enfoncement de portion proximale 60. Cela entraîne un déplacement de la tige 63 vers l'élément de contrôle 52, et l'actionnement de ce dernier par la portion active 64.By referring to the figure 7 , the flexibility of the flange 61 allows it to deform when actuating pressure is applied to the button 6. In practice, the side wall of the flange 61 deforms inside the ring 7 to allow the depression of the proximal portion 60. This causes a displacement of the rod 63 towards the control element 52, and the actuation of the latter by the active portion 64.

Il est avantageux que le bouton 6 puisse revenir automatiquement à la position de repos de la figure 5, après l'actionnement de l'élément de contrôle 52. Pour cela, on prévoit que la collerette 61 soit flexible avec des propriétés élastiques. L'utilisation d'une collerette 61 en silicone permet d'obtenir une bonne flexibilité avec de bonnes propriétés élastiques. Sans pression d'actionnement sur le bouton 6, la collerette 61 revient alors automatiquement dans sa position de repos non déformée. La tige 63 se déplace en sens inverse, de sorte que sa portion active 64 s'écarte de l'élément de contrôle 52.It is advantageous that the button 6 can automatically return to the rest position of the figure 5 , after actuation of the control element 52. For this, provision is made for the collar 61 to be flexible with elastic properties. The use of a silicone collar 61 makes it possible to obtain good flexibility with good elastic properties. Without pressing the button 6, the collar 61 then automatically returns to its non-deformed rest position. The rod 63 moves in the opposite direction, so that its active portion 64 moves away from the control element 52.

Le projecteur 1 qui vient d'être décrit est parfaitement étanche à l'eau et autonome, en ce sens qu'il n'a pas besoin d'être branché à une prise de courant pour fonctionner. Il apparaît avantageux que ce projecteur 1 soit équipé d'un moyen permettant de le fixer simplement et rapidement sur un support ou une paroi.The projector 1 which has just been described is perfectly watertight and self-contained, in the sense that it does not need to be connected to a power outlet to operate. It appears advantageous that this projector 1 is equipped with a means allowing it to be fixed simply and quickly on a support or a wall.

Sur les figures 2, 3, 4 et 8, la coque 2 est pourvue d'une fixation magnétique 8, permettant au projecteur 1 de se fixer contre des parois par aimantation.On the figures 2, 3 , 4 and 8 , the shell 2 is provided with a magnetic fixing 8, allowing the projector 1 to be fixed against the walls by magnetization.

Avantageusement, cette fixation 8 comprend une pièce amovible 81 réalisée dans un matériau aimanté ou un matériau ferromagnétique non aimanté (par ex : fer doux, acier doux, métal, ...). Cette pièce amovible 81 est disposée à l'arrière de la coque 2, et plus particulièrement contre la face externe de la paroi arrière 220 du manchon 22. Elle se présente par exemple sous la forme d'une rondelle aimantée dont le diamètre est inférieur ou égal à celui de la face arrière 220.Advantageously, this fixing 8 comprises a removable part 81 made of a magnetized material or a non-magnetic ferromagnetic material (for example: soft iron, mild steel, metal, etc.). This removable part 81 is arranged at the rear of the shell 2, and more particularly against the outer face of the rear wall 220 of the sleeve 22. It is for example in the form of a magnetic washer whose diameter is smaller than or equal to equal to that of the rear face 220.

Dans le mode de réalisation de la figure 4, la fixation 8 comprend également au moins une autre pièce 82 réalisée dans un matériau ferromagnétique non aimanté (par ex: fer doux, acier doux, métal, ...) ou un matériau aimanté. Cette autre pièce 82 est installée à l'intérieur de la chambre 4, et plus particulièrement contre la face interne de la paroi arrière 220 du manchon 22. Sur la figure 4, on utilise un ou plusieurs plots aimantés 82 qui sont fixés sur la face interne de la paroi arrière 220.In the embodiment of the figure 4 , the fixing 8 also comprises at least one other part 82 made of a non-magnetic ferromagnetic material (for example: soft iron, mild steel, metal, etc.) or a magnetic material. This other part 82 is installed inside the chamber 4, and more particularly against the internal face of the rear wall 220 of the sleeve 22. On the figure 4 , one or more magnetic pads 82 are used which are fixed to the internal face of the rear wall 220.

Les pièces 81 et 82 permettent de générer une force magnétique qui tend à maintenir la pièce amovible 81 contre la paroi arrière 220 du manchon 22. Cette force magnétique peut être obtenue de différentes manières :

  • avec une pièce amovible 81 aimantée et une pièce 82 également aimantée, les deux pièces ayant des pôles opposés pour qu'elles tendent à se coller l'une à l'autre ;
  • avec une pièce amovible 81 aimantée et une pièce 82 ferromagnétique non aimantée ;
  • avec une pièce amovible 81 ferromagnétique non aimantée et une pièce 82 aimantée.
The parts 81 and 82 make it possible to generate a magnetic force which tends to hold the removable part 81 against the rear wall 220 of the sleeve 22. This magnetic force can be obtained in different ways:
  • with a removable part 81 magnetized and a part 82 also magnetized, the two parts having opposite poles so that they tend to stick to each other;
  • with a removable magnetic part 81 and a non-magnetic ferromagnetic part 82;
  • with a removable non-magnetic ferromagnetic part 81 and a magnetic part 82.

Les pièces 81 et 82 sont agencées dans l'axe géométrique X de sorte que la force d'attraction magnétique soit également dans ledit axe.The parts 81 and 82 are arranged in the geometric axis X so that the magnetic attraction force is also in said axis.

Le projecteur 1 peut ainsi être facilement et rapidement fixé contre divers types de supports ou parois qui ne sont ni aimantés, ni ferromagnétiques. Comme illustré sur la figure 8a, il suffit pour cela de placer la pièce amovible 81 contre une face d'une paroi P (ou d'un support) et de plaquer la paroi arrière 220 du manchon 22 de l'autre côté de ladite paroi P, en vis-à-vis de ladite pièce amovible 81. La force d'attraction magnétique qui en résulte permet de maintenir le projecteur 1 contre la paroi P. Cette dernière peut être en verre, en bois, en plastique, etc. Bien évidement, l'épaisseur de la paroi P devra être suffisamment réduite pour que la force d'attraction magnétique puisse assurer un maintien satisfaisant du projecteur P.The projector 1 can thus be easily and quickly fixed against various types of supports or walls which are neither magnetized nor ferromagnetic. As shown on the figure 8a , it suffices for this to place the removable part 81 against one face of a wall P (or of a support) and to press the rear wall 220 of the sleeve 22 on the other side of said wall P, facing -vis of said removable part 81. The resulting magnetic force of attraction keeps the projector 1 against the wall P. The latter can be made of glass, wood, plastic, etc. Obviously, the thickness of the wall P must be sufficiently reduced so that the magnetic force of attraction can ensure satisfactory maintenance of the projector P.

La paroi P peut également être réalisée dans un matériau ferromagnétique non aimantée, par exemple en tôle métallique. Dans ce cas, la force d'attraction de la seule pièce amovible 81 aimantée (figure 8b) et/ou de la pièce 82 aimantée (figure 8c) est suffisante pour solidariser le projecteur 1 contre la paroi P.The wall P can also be made of a non-magnetized ferromagnetic material, for example sheet metal. In this case, the force of attraction of the single magnetic removable part 81 ( figure 8b ) and / or the magnetic part 82 ( figure 8c ) is sufficient to secure the projector 1 against the wall P.

On constate sur les figures 8a et 8b que le positionnement du bouton 6 directement sur l'optique 3 le rend aisément accessible et facilement manipulable par un utilisateur, même quand le projecteur 1 est installé contre une paroi P. En outre, le bouton 6 et la fixation magnétique 8 sont coaxiaux et alignés sur l'axe géométrique X. La pression d'actionnement du bouton 6 étant appliquée dans l'axe X, elle est alors appliquée dans la même direction que la force d'attraction magnétique. La fixation magnétique 8 n'est donc pas perturbée et le projecteur 1 reste parfaitement positionné sur la paroi P.We see on the figures 8a and 8b that the positioning of the button 6 directly on the optic 3 makes it easily accessible and easily manipulated by a user, even when the projector 1 is installed against a wall P. In addition, the button 6 and the magnetic fixing 8 are coaxial and aligned on the axis geometric X. The actuating pressure of the button 6 being applied in the X axis, it is then applied in the same direction as the magnetic attraction force. The magnetic fixing 8 is therefore not disturbed and the projector 1 remains perfectly positioned on the wall P.

La figure 8d illustre une variante de réalisation où le projecteur 1 est inséré dans une traversée de paroi T ou une buse de refoulement ou une prise balai existante déjà installée dans une paroi P d'une piscine ou d'un bassin. Dans ce cas, la paroi latérale externe 221 du manchon 22 peut être filetée de manière à ce que le projecteur 1 puisse se visser à l'intérieur de la traversée de paroi T ou de la buse de refoulement ou de la prise balai.The figure 8d illustrates an alternative embodiment where the projector 1 is inserted into a wall feedthrough T or an existing delivery nozzle or brush socket already installed in a wall P of a swimming pool or a basin. In this case, the outer side wall 221 of the sleeve 22 can be threaded so that the projector 1 can be screwed inside the wall feed-through T or the delivery nozzle or the brush socket.
