Abstract

The light fitting is constructed in two parts. The lamp (6) is fitted to a board (5) which also holds the circuitry (7) for powering the lamp. An end plate (4) is bonded to the board along with a bracket (25) that can be rotated from outside the plate (26). The second part of the fitting comprises the main tube (2) already sealed to a second end plate (3). Two guides (11) run through the tube from the plate and terminate in a ring (12) with keys (24) pressed into it. To assemble, the board is slid into the tube along the two guides. At the end of the board are two male connectors. These mate with two corresponding female connectors incorporated into end plate 3, thus providing the power connection to the board. Bracket 25 is then rotated from outside end plate 4 through half a turn. This latches against the keys in the end ring 12 and produces a compressing action sealing the end plate 4 against the tube.

Description

La présente invention concerne un appareil d'éclairage étanche, du type comprenant une enveloppe tubulaire dont au moins une partie est réalisée en une matière translucide ou transparente, et dont l'une des extrémités est obturée par un premier flasque fixé de manière étanche à l'enveloppe, une platine qui est insérable axialement dans l'enveloppe tubulaire à travers son autre extrémité et qui porte au moins une lampe et l'appareillage électrique nécessaire pour son alimentation en courant, des guides fixes à l'intérieur de l'enveloppe tubulaire pour le guidage axial de la platine dans l'enveloppe, un second flasque muni d'un joint annulaire d'étanchéité pour obturer de manière étanche ladite autre extrémité de l'enveloppe, et des moyens de serrage pour presser axialement le second flasque avec son joint annulaire d'étanchéité contre l'extrémité correspondante de l'enveloppe tubulaire.The present invention relates to a waterproof lighting apparatus, type comprising a tubular casing of which at least part is made of a translucent or transparent material, and one of the ends is closed by a first flange tightly fixed to the envelope, a plate which is axially insertable in the envelope tubular through its other end and which carries at least one lamp and the electrical equipment necessary for its current supply, fixed guides inside the tubular casing for axial guidance of the plate in the envelope, a second flange provided with an annular seal sealing to seal off said other end of the envelope, and clamping means for axially pressing the second flange with its annular seal against the end corresponding of the tubular envelope.

Les appareils d'éclairage du type décrit ci-dessus sont bien connus et sont commercialisés par la demanderesse depuis plusieurs années. Ils sont par exemple décrits dans le brevet FR-2 316 536. Dans ces appareils connus, après avoir été insérée axialement dans l'enveloppe tubulaire, à la fin du mouvement d'insertion, la platine est accrochée automatiquement au premier flasque, c'est-à-dire au flasque qui est scellé à l'enveloppe tubulaire, au moyen d'un dispositif de verrouillage à encliquetage automatique, qui peut être déverrouillé par une commande située à l'autre extrémité de la platine. Cette autre extrémité de la platine porte un écrou ou une tige filetée, qui est coaxiale à l'enveloppe tubulaire. Les moyens de serrage susmentionnés, destinés à presser axialement le second flasque avec son joint annulaire d'étanchéité contre l'extrémité correspondante de l'enveloppe tubulaire, sont alors constitués soit par une vis, soit par un écrou, selon que la platine porte un écrou ou une tige filetée.Lighting devices of the type described above are well known and have been marketed by the applicant for several years. They are for example described in patent FR-2 316 536. In these devices known, after having been inserted axially in the tubular casing, at the end of the insertion movement, the plate is automatically hooked to the first flange, i.e. the flange which is sealed to the envelope tubular, by means of a latching locking device automatic, which can be unlocked by a control located at the other end of the plate. This other end of the plate carries a nut or a threaded rod, which is coaxial with the tubular casing. The means of aforementioned clamping, intended to axially press the second flange with its annular seal against the corresponding end of the tubular casing, are then constituted either by a screw, or by a nut, depending on whether the plate carries a nut or a threaded rod.

Jusqu'à présent, les appareils d'éclairage connus du type sus-indiqué ont donné satisfaction. Toutefois, l'engagement de la vis de serrage dans l'écrou, qui doit se faire en faisant tout d'abord passer la vis à travers le trou central du second flasque, puis dans l'écrou de la platine, ou, selon le cas, l'engagement de la tige filetée de la platine à travers le trou central du second flasque et ensuite la mise en place de l'écrou sur l'extrémité dépassante de la tige filetée sont des opérations relativement fastidieuses qui nécessitent parfois un certain tâtonnement. En outre, pour serrer la vis ou, selon le cas l'écrou, il faut lui faire faire plusieurs tours, ce qui, là encore, est une opération relativement longue et fastidieuse.Up to now, the known lighting devices of the above-mentioned type have given satisfaction. However, the engagement of the clamping screw in the nut, which must be done by first passing the screw through the central hole of the second flange, then in the nut of the plate, or, depending on the case, the engagement of the threaded rod of the plate through the central hole of the second flange and then placing the nut on the end protruding from the threaded rod are relatively tedious operations which sometimes require some trial and error. Also, to tighten the screw or, as the case may be, the nut must be made to make several turns, which, there still, is a relatively long and tedious operation.

La présente invention a donc pour but de remédier aux inconvénients précités de ces appareils d'éclairage connus.The object of the present invention is therefore to remedy the drawbacks above of these known lighting fixtures.

A cet effet, l'appareil d'éclairage selon l'invention est caractérisé en ce que le second flasque est fixé à la platine de façon à former avec elle un ensemble mobile d'un seul tenant, et en ce que les moyens de serrage sont réalisés sous la forme d'un dispositif de verrouillage comportant au moins deux éléments fixes d'appui, qui sont disposés à l'intérieur de l'enveloppe tubulaire, près de ladite autre extrémité de celle-ci, au moins un élément mobile de verrouillage qui est porté par le second flasque, du côté de celui-ci tourné vers l'intérieur de l'enveloppe tubulaire, et qui est relié fonctionnellement à un organe rotatif de manoeuvre passant de manière étanche à travers le second flasque, au centre de celui-ci, de façon à pouvoir être actionné depuis l'extérieur de l'appareil d'éclairage, et des moyens formant came aptes à convertir un mouvement de rotation de l'organe de manoeuvre en un déplacement axial d'amplitude prédéfinie de l'élément mobile de verrouillage dans un sens tel que, lorsque la platine a été insérée dans l'enveloppe tubulaire jusqu'à ce que le joint annulaire d'étanchéité du second flasque se trouve pratiquement en contact avec l'extrémité correspondante de l'enveloppe tubulaire, une première rotation de l'organe de manoeuvre sur une fraction de tour amène l'élément mobile de verrouillage derrière les deux éléments fixes d'appui, et qu'une rotation supplémentaire de l'organe de manoeuvre sur une autre fraction de tour provoque, par réaction entre l'élément mobile de verrouillage et les deux éléments fixes d'appui et en coopération avec les moyens formant came, un déplacement axial du second flasque pour presser ledit joint annulaire d'étanchéité contre l'extrémité correspondante de l'enveloppe tubulaire.To this end, the lighting apparatus according to the invention is characterized in that that the second flange is fixed to the plate so as to form with it a movable unit in one piece, and in that the clamping means are produced in the form of a locking device comprising at least two fixed support elements, which are arranged inside the envelope tubular, near said other end thereof, at least one element locking mobile which is carried by the second flange, on the side thereof facing the inside of the tubular casing, and which is connected functionally to a rotary actuator passing so watertight through the second flange, in the center thereof, so that be operable from outside the lighting fixture, and cam means capable of converting a rotational movement from the operating member in an axial displacement of predefined amplitude of the movable locking element in a direction such that, when the plate has been inserted into the tubular casing until the annular seal sealing of the second flange is practically in contact with the corresponding end of the tubular casing, a first rotation of the actuator on a fraction of a turn brings the movable element locking behind the two fixed support elements, and that a rotation additional actuator on another fraction of a turn causes, by reaction between the movable locking element and the two fixed support elements and in cooperation with the cam means, an axial displacement of the second flange to press said annular seal sealing against the corresponding end of the tubular casing.

De préférence, le dispositif de verrouillage est un dispositif à double effet du type demi-tour, c'est-à-dire qu'il suffit de faire tourner son organe de manoeuvre d'environ un demi tour pour effectuer le verrouillage du second flasque et la mise en pression de son joint annulaire d'étanchéité contre l'extrémité correspondante de l'enveloppe tubulaire. Ainsi, avec l'appareil d'éclairage étanche selon l'invention, l'insertion de la platine de l'enveloppe tubulaire, le verrouillage et le déverrouillage du second flasque par rapport à l'enveloppe tubulaire et l'enlèvement de la platine peuvent être effectués de manière très simple et rapide.Preferably, the locking device is a double device effect of the U-turn type, that is to say it suffices to rotate its organ about half a turn to lock the second flange and the pressurization of its annular seal against the corresponding end of the tubular casing. So with the waterproof lighting device according to the invention, the insertion of the plate of the tubular casing, the locking and unlocking of the second flange relative to the tubular casing and the removal of the plate can be done very simply and quickly.

    • L'appareil d'éclairage 1 représenté dans la figure 1 se compose essentiellement d'une enveloppe tubulaire 2, en une matière transparente ou translucide, qui a par exemple une section transversale de forme circulaire, dont les extrémités sont obturées ou obturables de manière étanche respectivement par des flasques 3 et 4, également de forme circulaire si l'enveloppe 2 a une section circulaire. L'appareil d'éclairage 1 comporte en outre une platine 5 qui porte, d'un côté, au moins une lampe 6, par exemple une lampe fluorescente, et, de l'autre côté, l'appareillage électrique nécessaire pour l'alimentation en courant de la lampe 6, comme par exemple un ballast 7, un amorçeur ou starter (non montré), au moins deux fiches mâles de connexion (une seule de ces deux fiches 8 est visible dans les figures 1, 4 et 7), ainsi que les conducteurs électriques reliant ces éléments les uns aux autres.The lighting fixture 1 shown in Figure 1 consists of essentially of a tubular casing 2, made of a transparent material or translucent, which has for example a cross section of shape circular, the ends of which are closed or closable waterproof respectively by flanges 3 and 4, also in shape circular if the envelope 2 has a circular section. The light fixture 1 further comprises a plate 5 which carries, on one side, at least one lamp 6, for example a fluorescent lamp, and, on the other side, the switchgear electrical supply necessary for the power supply of the lamp 6, as for example a ballast 7, a starter or choke (not shown), at least two male connection plugs (only one of these two 8 plugs is visible in Figures 1, 4 and 7), as well as the electrical conductors connecting these elements to each other.

    Chacun des deux flasques 3 et 4 peut être par exemple réalisé en une tôle métallique conformée par exemple par emboutissage, de manière à présenter une gorge périphérique circulaire dans laquelle peut être engagé le bord circulaire de l'extrémité correspondante de l'enveloppe 2. Le flasque 3 est fixé rigidement, de manière connue, à l'enveloppe 2, par exemple au moyen d'un ciment de scellement 9 (figures 4 et 7).Each of the two flanges 3 and 4 can for example be made in one metal sheet shaped for example by stamping, so as to have a circular peripheral groove in which can be engaged the circular edge of the corresponding end of the envelope 2. The flange 3 is rigidly fixed, in known manner, to the casing 2, by example using a sealing cement 9 (Figures 4 and 7).

    La platine 5 peut être insérée axialement à l'intérieur de l'enveloppe 2 en y étant guidée et supportée par deux guides fixes 11. Les deux guides 11 peuvent être par exemple constitués par des rails profilés à section en C, disposés à l'intérieur de l'enveloppe 2, comme montré dans les figures 2, 5 et 8. A une de leurs extrémités, du côté du flasque 4, les rails 11 sont fixés rigidement par soudage, collage, rivetage ou par tout autre moyen approprié à un anneau de support 12 dont le diamètre est égal ou légèrement plus petit que le diamètre intérieur de l'enveloppe tubulaire 2. A leur autre extrémité, les rails 11 sont fixés rigidement, par exemple par collage, soudage, rivetage ou par tout autre moyen approprié, à une plaque de support 13, pliée en forme d'équerre, qui est elle-même fixée rigidement au flasque 3. La plaque de support 13 porte une paire de fiches femelles de connexion 14 (une seule de ces deux fiches 14 est visible dans les figures 1, 4 et 7), qui sont respectivement alignées avec les deux fiches mâles de connexion 8 portées par la platine 5 dans la région de son extrémité qui est voisine du flasque 3. Ainsi, lorsque la platine 5 est introduite axialement à l'intérieur de l'enveloppe tubulaire 2 et que son extrémité frontale parvient à proximité du flasque 3, les plots de contact 15 des fiches mâles de connexion 8 s'engagent respectivement dans les fiches femelles de connexion 14. Les contacts 16 de ces fiches femelles 14 sont reliés électriquement aux conducteurs d'un cordon d'alimentation 17 qui passe à travers un trou du flasque 3, via une traversée étanche 18 constituée par exemple par un presse-étoupe.The plate 5 can be inserted axially inside the envelope 2 by being guided and supported by two fixed guides 11. The two guides 11 may for example consist of profiled rails with a cross-section C, arranged inside the envelope 2, as shown in the figures 2, 5 and 8. At one of their ends, on the side of the flange 4, the rails 11 are rigidly fixed by welding, gluing, riveting or by any other means suitable for a support ring 12 whose diameter is equal or slightly smaller than the inside diameter of the tubular casing 2. At their other end, the rails 11 are rigidly fixed, for example by bonding, welding, riveting or by any other appropriate means, to a plate support 13, folded in a square shape, which is itself rigidly fixed to the flange 3. The support plate 13 carries a pair of female plugs connection 14 (only one of these two plugs 14 is visible in the Figures 1, 4 and 7), which are respectively aligned with the two sheets connection males 8 carried by the plate 5 in the sound region end which is close to the flange 3. Thus, when the plate 5 is introduced axially inside the tubular casing 2 and that its front end comes close to the flange 3, the contact pads 15 male connection plugs 8 respectively engage in the connection sockets 14. Contacts 16 of these sockets 14 are electrically connected to the conductors of a power cord 17 which passes through a hole in the flange 3, via a sealed bushing 18 constituted for example by a cable gland.

    D'autre part, le flasque 4 de l'appareil d'éclairage 1 est muni d'un joint annulaire d'étanchéité 19, par exemple en une matière élastomère, qui est disposé dans sa gorge annulaire périphérique 4a comme cela est plus particulièrement visible dans la figure 11. L'appareil d'éclairage 1 comporte en outre, de façon connue en soi, des moyens de serrage 20 pour presser axialement le second flasque 4, avec son joint annulaire d'étanchéité 19, contre l'extrémité correspondante de l'enveloppe tubulaire 2. On the other hand, the flange 4 of the lighting device 1 is provided with a seal sealing ring 19, for example of an elastomeric material, which is arranged in its peripheral annular groove 4a as is more particularly visible in Figure 11. The lighting fixture 1 comprises in addition, in a manner known per se, clamping means 20 for pressing axially the second flange 4, with its annular seal 19, against the corresponding end of the tubular casing 2.

    Conformément à la présente invention, le flasque 4 est fixé rigidement à la platine 5 de manière à former avec elle un ensemble mobile d'un seul tenant. A cet effet, il est par exemple prévu une plaque 21 (figure 10) qui est fixée à la face intérieure du flasque 4, par exemple par soudage par points ou par collage, et qui comporte deux languettes de fixation 22 (figures 10 et 11) obtenues par découpage et pliage de la plaque 21. La platine 5 est supportée par les deux languettes 22 et fixée à celles-ci par exemple par collage, soudage par points, rivetage ou boulonnage ou par tout autre moyen approprié de fixation.According to the present invention, the flange 4 is rigidly fixed to plate 5 so as to form with it a mobile assembly of a single holding. For this purpose, there is for example provided a plate 21 (Figure 10) which is fixed to the inner face of the flange 4, for example by welding by points or by gluing, and which has two fixing tabs 22 (Figures 10 and 11) obtained by cutting and folding the plate 21. The plate 5 is supported by the two tabs 22 and fixed to them by example by gluing, spot welding, riveting or bolting or by any other appropriate means of attachment.

    Conformément à la présente invention, les moyens de serrage 20 susmentionnés sont réalisés sous la forme d'un dispositif de verrouillage 23 comportant au moins deux éléments fixes d'appui 24, au moins un élément mobile de verrouillage 25 pouvant être actionné au moyen d'un organe de manoeuvre 26, et des moyens formant came 27 aptes à convertir un mouvement de rotation de l'organe de manoeuvre 26 en un déplacement axial de l'élément mobile de verrouillage 25.In accordance with the present invention, the above-mentioned clamping means 20 are made in the form of a locking device 23 comprising at least two fixed support elements 24, at least one element locking mobile 25 which can be actuated by means of a maneuver 26, and cam means 27 capable of converting a rotational movement of the operating member 26 in one movement axial of the movable locking element 25.

    Les deux éléments fixes d'appui 24 peuvent être par exemple constitués par des languettes découpées dans la matière de l'anneau 12 et rabattues vers le centre de celui-ci, les deux languettes 24 étant situées dans des positions diamétralement opposées de l'anneau 12.The two fixed support elements 24 can for example be formed by tabs cut from the material of the ring 12 and folded towards the center thereof, the two tabs 24 being located in diametrically opposite positions of the ring 12.

    L'élément mobile de verrouillage 25 peut être constitué par une lame rigide, qui s'étend diamétralement à l'intérieur de l'enveloppe tubulaire 2 et qui est fixée rigidement en son milieu à un axe 28. Cet axe 28 est monté à rotation au centre du flasque 4 et est relié mécaniquement à l'organe de manoeuvre 26 par lesdits moyens formant came 27.The movable locking element 25 may consist of a blade rigid, which extends diametrically inside the tubular casing 2 and which is rigidly fixed in the middle to an axis 28. This axis 28 is mounted at rotation in the center of the flange 4 and is mechanically connected to the operation 26 by said cam means 27.

    Comme cela est plus particulièrement visible dans les figures 11 et 12, le dispositif de verrouillage 23 comporte un corps cylindrique creux 29 qui est fixé rigidement au milieu du flasque 4. A cet effet, le corps cylindrique creux 29 comporte un collet 29a et un filetage extérieur 29b qui passe à travers un trou central du flasque 4 et sur lequel est vissé un écrou 31. Le bord du trou central du flasque 4 est pris en sandwich entre le collet 29a et l'écrou 31, avec interposition d'au moins une rondelle d'étanchéité 32. Le corps cylindrique creux 29 présente un alésage axial 33 (figure 12) qui est ouvert du côté extérieur du flasque 4 et qui est fermé du côté intérieur dudit flasque par une paroi de fond 29c présentant un trou 34 en son milieu. L'organe de manoeuvre 26 comporte une partie cylindrique 35, en forme de douille, qui est montée à rotation dans l'alésage 33 du corps cylindrique creux 29. Un circlips 36 encliqueté dans des gorges circulaires formées mutuellement en vis à vis respectivement dans la surface cylindrique de l'alésage 33 et dans la surface cylindrique de la partie 35 en forme de douille empêche tout mouvement axial de cette dernière à l'intérieur de l'alésage 33. Un joint torique 37 disposé dans une gorge circulaire formée dans la surface cylindrique de la partie 35 en forme de douille assure l'étanchéité entre cette dernière et le corps 29. La partie cylindrique 35 en forme de douille présente un trou axial borgne 38 qui est ouvert en direction de la paroi de fond 29c du corps cylindrique creux 29. L'axe 28 passe à travers le trou 34 de la paroi de fond 29c et pénètre à l'intérieur du trou axial borgne 38 jusqu'à une certaine distance du fond de ce trou 38. Un ressort hélicoïdal de compression 39 peut être disposé entre le fond du trou 38 et l'extrémité de l'axe 28 engagée à l'intérieur dudit trou 38. Sur approximativement la moitié de sa longueur, du côté de la paroi de fond 29c et du corps cylindrique creux 29, le trou 38 comporte une partie qui présente un plus grand diamètre intérieur que la partie restante du trou 38. Un manchon 41, qui est fixe par rapport au corps cylindrique creux 29, s'étend coaxialement dans la partie de plus grand diamètre intérieur du trou 38, sur toute la longueur de cette partie, depuis la paroi de fond 29c du corps cylindrique creux 29. Ainsi, le manchon 41 est immobilisé axialement entre la paroi de fond 29c et l'épaulement annulaire formé entre les deux parties de diamètres différents du trou 38. Le manchon 41 est également immobilisé en rotation par rapport au corps cylindrique creux 29, par exemple au moyen d'au moins un ergot 41a qui est engagé dans une encoche correspondante formée dans le bord du trou 34. As is more particularly visible in Figures 11 and 12, the locking device 23 comprises a hollow cylindrical body 29 which is rigidly fixed in the middle of the flange 4. For this purpose, the body hollow cylindrical 29 has a collar 29a and an external thread 29b which passes through a central hole in the flange 4 and onto which a nut is screwed 31. The edge of the central hole of the flange 4 is sandwiched between the collar 29a and the nut 31, with the interposition of at least one sealing washer 32. The hollow cylindrical body 29 has an axial bore 33 (FIG. 12) which is open on the outside of the flange 4 and which is closed on the side inside of said flange by a bottom wall 29c having a hole 34 in his middle. The operating member 26 comprises a cylindrical part 35, in the form of a socket, which is rotatably mounted in the bore 33 of the body hollow cylindrical 29. A circlip 36 snapped into circular grooves formed opposite each other respectively in the surface cylindrical of bore 33 and in the cylindrical surface of part 35 in sleeve shape prevents axial movement of the latter at inside the bore 33. An O-ring 37 disposed in a groove circular formed in the cylindrical surface of the 35-shaped part socket provides sealing between the latter and the body 29. The part cylindrical 35 in the form of a socket has a blind axial hole 38 which is open towards the bottom wall 29c of the hollow cylindrical body 29. The axis 28 passes through the hole 34 of the bottom wall 29c and enters the inside of the blind axial hole 38 up to a certain distance from the bottom of this hole 38. A helical compression spring 39 can be disposed between the bottom of the hole 38 and the end of the axis 28 engaged inside the said hole 38. Over approximately half of its length, on the side of the bottom wall 29c and of the hollow cylindrical body 29, the hole 38 has a part which has a larger internal diameter than the remaining part of the hole 38. A sleeve 41, which is fixed relative to the cylindrical body hollow 29, extends coaxially in the portion of larger diameter inside of hole 38, over the entire length of this part, from the wall of bottom 29c of the hollow cylindrical body 29. Thus, the sleeve 41 is immobilized axially between the bottom wall 29c and the annular shoulder formed between the two parts of different diameters of the hole 38. The sleeve 41 is also immobilized in rotation relative to the body hollow cylindrical 29, for example by means of at least one lug 41a which is engaged in a corresponding notch formed in the edge of the hole 34.

    Comme montré dans la figure 13, la partie cylindrique 35 en forme de douille de l'organe de manoeuvre 26 comporte, dans sa paroi cylindrique, au moins une fente oblique 42, par exemple deux fentes hélicoïdales 42 disposées symétriquement par rapport à l'axe longitudinal 43 de la partie cylindrique 35. De même, comme montré dans la figure 14, le manchon fixe 41 comporte, dans sa paroi cylindrique, au moins une fente 44 en L, de préférence deux fentes 44 disposées symétriquement par rapport à l'axe longitudinal 45 du manchon 41, cet axe 45 étant, en service, confondu avec l'axe 43 de la partie cylindrique 35. Chacune des deux fentes 44 en L comporte une partie rectiligne 44a, qui s'étend parallèlement à l'axe 45, et une partie 44b qui s'étend circonférenciellement sur un arc d'environ 90° à partir de l'extrémité de la partie rectiligne 44a qui est la plus proche de la paroi de fond 29c du corps cylindrique creux 29.As shown in FIG. 13, the cylindrical part 35 in the form of sleeve of the operating member 26 comprises, in its cylindrical wall, at least one oblique slot 42, for example two helical slots 42 arranged symmetrically with respect to the longitudinal axis 43 of the part cylindrical 35. Likewise, as shown in FIG. 14, the sleeve fixed 41 has, in its cylindrical wall, at least one slot 44 in L, of preferably two slots 44 arranged symmetrically with respect to the axis longitudinal 45 of sleeve 41, this axis 45 being, in service, coincident with the axis 43 of the cylindrical part 35. Each of the two slots 44 in L comprises a rectilinear part 44a, which extends parallel to the axis 45, and a portion 44b which extends circumferentially over an arc of approximately 90 ° to from the end of the straight part 44a which is closest to the bottom wall 29c of the hollow cylindrical body 29.

    Au moins un ergot 46 fait radialement saillie sur l'axe 28 et s'engage successivement dans la fente 44 en L et dans la fente oblique 42. Dans le cas où il y a deux fentes obliques 42 et deux fentes 44 en L, l'axe 28 comporte deux ergots 46 diamétralement opposés, engagés chacun dans une paire de fentes correspondantes 42 et 44 de la partie cylindrique 35 et du manchon fixe 41. Les deux ergots 46 peuvent être constitués par les extrémités opposées et dépassantes d'une cheville qui passe à travers un trou percé diamétralement dans l'axe 28, comme montré dans la figure 12.At least one lug 46 protrudes radially on the axis 28 and engages successively in the slot 44 in L and in the oblique slot 42. In the case where there are two oblique slots 42 and two slots 44 in L, the axis 28 comprises two diametrically opposite lugs 46, each engaged in a pair of corresponding slots 42 and 44 of the cylindrical part 35 and of the fixed sleeve 41. The two pins 46 can be constituted by the opposite and protruding ends of a dowel which passes through a hole drilled diametrically in the axis 28, as shown in Figure 12.

    La partie cylindrique 35 de l'organe de manoeuvre 26 peut être entraínée manuellement en rotation en agissant sur la partie 47 de l'organe de manoeuvre qui se trouve à l'extérieur du corps cylindrique creux 29, du côté extérieur du flasque 4. La partie 47 de l'organe de manoeuvre 26, qui a par exemple une forme plane, peut être réalisée d'une seule pièce avec la partie cylindrique 35 ou, comme cela est montré dans la figure 12, la partie 47 peut être constituée par une pièce distincte de la partie cylindrique 35. Dans ce dernier cas, la partie cylindrique 35 peut présenter un trou borgne 48, à section non circulaire, par exemple hexagonale, et la pièce 47 peut alors comporter une courte tige 49, qui a une section non circulaire correspondant à celle du trou 48. Ainsi, en engageant la courte tige 49 dans le trou 48, la pièce 47 peut être utilisée comme une clé pour faire tourner la partie cylindrique 35 à l'intérieur du corps cylindrique creux 29.The cylindrical part 35 of the operating member 26 can be driven manually in rotation by acting on part 47 of the member operating which is outside the hollow cylindrical body 29, of the outer side of the flange 4. The part 47 of the operating member 26, which for example has a flat shape, can be made in one piece with the cylindrical part 35 or, as shown in FIG. 12, the part 47 can be made up of a separate part from the part cylindrical 35. In the latter case, the cylindrical part 35 may have a blind hole 48, of non-circular section, for example hexagonal, and the part 47 can then include a short rod 49, which has a non-cross section circular corresponding to that of hole 48. Thus, by engaging the short rod 49 in hole 48, piece 47 can be used as a wrench to rotate the cylindrical part 35 inside the hollow cylindrical body 29.

    Lorsque l'organe de manoeuvre 26 se trouve dans la position représentée dans la figure 12, chacune des extrémités dépassantes de la cheville 46 se trouve à l'extrémité 42a de la fente 42 et à l'extrémité 44c de la partie arquée 44b de la fente 44. Quand l'organe de manoeuvre 26 est entraíné manuellement en rotation, sa partie cylindrique 35 agit sur les extrémités dépassantes de la cheville 46 pour la faire tourner dans un plan perpendiculaire à l'axe 43 et ce faisant, la cheville 46 fait tourner l'axe 28. Pendant ce mouvement de rotation, tant que les extrémités dépassantes de la cheville 46 parcourent la partie arquée 44b des fentes 44, l'axe 28 est uniquement animé d'un mouvement de rotation. Ensuite, lorsque les extrémités dépassantes de la cheville 46 arrivent à l'autre extrémité de la partie arquée 44b de chaque fente 44, donc à l'une des extrémités de la partie rectiligne 44a de chacune des deux fentes 44, le mouvement de rotation de la cheville 46 est arrêté, ainsi que le mouvement de rotation de l'axe 28. Ensuite, une rotation supplémentaire de la partie cylindrique 35 de l'organe de manoeuvre 26 oblige les extrémités dépassantes de la cheville 46 à se déplacer le long de la partie rectiligne 44a de chaque fente 44, en raison de l'action des fentes obliques 42. Il en résulte que l'axe 28 est déplacé axialement dans le sens de la flèche H montré dans la figure 12, tout en comprimant le ressort 39. Bien entendu, un mouvement de rotation de l'organe de manoeuvre 26 en sens inverse produirait tout d'abord un déplacement axial de l'axe 28 dans le sens opposé au sens de la flèche H, puis un mouvement de rotation de l'axe 28 dans le même sens que celui de l'organe de manoeuvre 26.When the operating member 26 is in the position shown in Figure 12, each of the projecting ends of the pin 46 is at the end 42a of the slot 42 and at the end 44c of the arcuate part 44b of the slot 44. When the operating member 26 is manually rotated, its cylindrical part 35 acts on the protruding ends of the pin 46 to rotate it in a plane perpendicular to the axis 43 and in doing so, the pin 46 rotates the axis 28. During this rotational movement, as long as the protruding ends of the pin 46 run through the arcuate part 44b of the slots 44, the axis 28 is only animated by a rotational movement. Then when the protruding ends of the dowel 46 arrive at the other end of the arcuate part 44b of each slot 44, therefore at one end of the rectilinear part 44a of each of the two slots 44, the movement of ankle rotation 46 is stopped, as well as the rotational movement of the axis 28. Next, an additional rotation of the cylindrical part 35 of the operating member 26 forces the projecting ends of the dowel 46 to move along the straight portion 44a of each slot 44, due to the action of the oblique slots 42. It follows that the axis 28 is moved axially in the direction of the arrow H shown in the figure 12, while compressing the spring 39. Of course, a movement of rotation of the operating member 26 in the opposite direction would produce everything first an axial displacement of the axis 28 in the opposite direction to the direction of arrow H, then a rotational movement of axis 28 in the same direction than that of the operating member 26.

    On va maintenant décrire comment sont assemblés les éléments de l'appareil d'éclairage 1 qui a été décrit ci-dessus. Partant de l'état représenté dans la figure 1, la platine 5 est introduite axialement à l'intérieur de l'enveloppe tubulaire 2 jusqu'à ce qu'elle parvienne dans la position montrée dans la figure 4. Dans cette position, le joint annulaire d'étanchéité 19 du flasque 4 est en contact ou presque en contact avec l'extrémité correspondante de l'enveloppe tubulaire 2, mais il n'est pas comprimé, et les plots de contact 15 des fiches mâles de connexion 8 sont respectivement engagés dans les fiches femelles de connexion 14, mais ils ne sont pas encore en contact électrique avec les contacts 16 desdites fiches femelles. A ce moment, une première rotation d'environ un quart de tour de l'organe de manoeuvre 26, comme montré dans la figure 6, amène la lame mobile de verrouillage 25 derrière les éléments fixes d'appui 24 formés sur l'anneau 12, comme montré dans la figure 5. Une rotation supplémentaire d'environ un quart de tour de l'organe de manoeuvre 26 tend à provoquer un déplacement axial de l'axe 28 et de la lame de verrouillage 25 en direction du côté gauche de l'appareil d'éclairage (vu dans les figures 4 et 7). Toutefois, comme la lame 25 est alors en appui contre les éléments fixes d'appui 24, c'est en réalité le flasque 4 et la platine 5 qui se déplacent vers la droite, de sorte que le joint annulaire d'étanchéité 19 est pressé contre l'extrémité correspondante de l'enveloppe tubulaire 2, assurant ainsi la fermeture étanche de l'appareil d'éclairage. Simultanément, le contact électrique est établi entre les plots de contact 15 et les contacts 16.We will now describe how the elements of the lighting apparatus 1 which has been described above. Starting from the state shown in Figure 1, the plate 5 is introduced axially at inside the tubular casing 2 until it reaches the position shown in figure 4. In this position, the annular seal seal 19 of the flange 4 is in contact or almost in contact with the corresponding end of the tubular casing 2, but it is not compressed, and the contact pads 15 of the male connection plugs 8 are respectively engaged in the female connection plugs 14, but they are not yet in electrical contact with the contacts 16 of said female plugs. At this time, a first rotation of about a quarter of turn of the operating member 26, as shown in Figure 6, brings the movable locking blade 25 behind the fixed support elements 24 formed on the ring 12, as shown in Figure 5. A rotation additional approximately a quarter turn of the actuator 26 tends to cause an axial displacement of the axis 28 and the blade locking 25 towards the left side of the luminaire (seen in Figures 4 and 7). However, as the blade 25 is then in abutment against the fixed support elements 24, it is in reality the flange 4 and the plate 5 which move to the right, so that the annular seal seal 19 is pressed against the corresponding end of the casing tubular 2, thus ensuring the watertight closure of the lighting fixture. Simultaneously, the electrical contact is established between the contact pads 15 and contacts 16.

    Il va de soi que la forme d'exécution de la présente invention qui a été décrite ci-dessus a été donnée à titre d'exemple purement indicatif et nullement limitatif, et que de nombreuses modifications peuvent être facilement apportées par l'homme de l'art sans pour autant sortir du cadre de l'invention. C'est ainsi notamment que les appuis fixes 24 peuvent être réalisés sous la forme de rampes de telle sorte que lors de la rotation de la lame de verrouillage 25, les extrémités de celle-ci glissent sur les éléments d'appui en forme de rampe afin de provoquer un déplacement axial de l'ensemble lame 25, axe 28, corps cylindrique creux 9 et flasque 4, ce déplacement axial produisant déjà une compression du joint annulaire d'étanchéité 19. Si on le désire, le déplacement axial du flasque 4 pour comprimer le joint d'étanchéité 19 pourrait être obtenu uniquement par rotation de la lame 25 et glissement de ses extrémités sur les éléments fixes d'appui 24 en forme de rampe. Dans ce cas, la construction du mécanisme de verrouillage 23 peut être simplifiée, car il suffit que l'axe 28 soit simplement monté à rotation, sans possibilité de mouvement axial, dans le corps cylindrique creux 29, et l'on peut se passer des moyens formant came qui sont constitués par les fentes 42 et 44 et par la cheville 46, la fonction de came étant alors remplie par les éléments d'appui en forme de rampe. Toutefois, dans ce dernier cas, l'utilisateur doit exercer sur l'organe de manoeuvre 26 un couple de force plus important que dans le cas du mode de réalisation décrit plus haut.It goes without saying that the embodiment of the present invention which has been described above was given as a purely indicative example and in no way limitative, and that many modifications can be easily made by those skilled in the art without departing from the scope of the invention. Thus in particular that the fixed supports 24 can be made in the form of ramps so that when rotating the locking blade 25, the ends of the latter slide on the elements support in the form of a ramp in order to cause an axial displacement of the blade 25, axle 28, hollow cylindrical body 9 and flange 4 assembly, this axial displacement already producing compression of the annular seal seal 19. If desired, the axial displacement of the flange 4 to compress the seal 19 could only be obtained by rotation of the blade 25 and sliding of its ends on the elements fixed support 24 in the form of a ramp. In this case, the construction of the locking mechanism 23 can be simplified, as it suffices that the pin 28 either simply rotatably mounted, with no possibility of axial movement, in the hollow cylindrical body 29, and we can do without the means forming a cam which are constituted by the slots 42 and 44 and by the pin 46, the cam function then being fulfilled by the support elements in ramp shape. However, in the latter case, the user must exercise on the actuator 26 a greater torque than in the case of the embodiment described above.

    En outre, le nombre des éléments d'appui fixes 24 n'est pas limité à deux, mais il pourrait être égal à trois ou plus, les éléments fixes d'appui étant alors disposés à intervalles réguliers le long de la circonférence de l'anneau 12. Dans ce cas, l'élément mobile de verrouillage 25 peut être réalisé sous la forme d'une étoile à plusieurs branches, le nombre des branches correspondant à celui des éléments fixes d'appui 24.In addition, the number of fixed support elements 24 is not limited to two, but it could be three or more, the fixed support elements then being arranged at regular intervals along the circumference of the ring 12. In this case, the movable locking element 25 can be made in the form of a star with several branches, the number of branches corresponding to that of the fixed support elements 24.

    Suivant une autre variante de réalisation, au lieu d'utiliser un élément mobile de verrouillage du type rotatif (lame 25), on peut utiliser deux ou plus de deux éléments de verrouillage montés sur la flasque 4 ou sur un support approprié lié au flasque 4, de façon à être mobiles radialement dans des directions opposées, en réponse à une rotation de l'organe de manoeuvre, ainsi que des éléments fixes d'appui présentant une partie en forme de rampe propre à provoquer un déplacement axial du flasque 4 en réponse au déplacement radial des éléments mobiles de verrouillage et au glissement de leurs extrémités sur la partie en forme de rampe des éléments fixes d'appui.According to another alternative embodiment, instead of using an element rotary type locking mobile (blade 25), two or more more than two locking elements mounted on the flange 4 or on a suitable support linked to the flange 4, so as to be radially movable in opposite directions, in response to a rotation of the operation, as well as fixed support elements having a part in form of ramp capable of causing axial displacement of the flange 4 in response to the radial displacement of the movable locking elements and to the sliding of their ends on the ramp-shaped part of the fixed support elements.
