Definitions

  • 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.
  • 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.
  • 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.
  • the object of the present invention is therefore to remedy the drawbacks above of these known lighting fixtures.
  • the lighting apparatus 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
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the flange 4 is rigidly fixed to plate 5 so as to form with it a mobile assembly of a single holding.
  • 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.
  • 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.
  • 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.
  • 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.
  • the locking device 23 comprises a hollow cylindrical body 29 which is rigidly fixed in the middle of the flange 4.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • piece 47 can be used as a wrench to rotate the cylindrical part 35 inside the hollow cylindrical body 29.
  • 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.
  • 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.
  • the axis 28 is only animated by a rotational movement.
  • 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).
  • 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.
  • the electrical contact is established between the contact pads 15 and contacts 16.
  • 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.
  • 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.
  • 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.
  • the user must exercise on the actuator 26 a greater torque than in the case of the embodiment described above.
  • 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.
  • 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.
  • 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.
