Definitions

  • the present invention relates in general to lighting portholes, that is to say the luminaires which, commonly called portholes, are intended to be applied as a wall light on any support surface, such as wall or ceiling.
  • the corresponding lighting portholes generally comprise, to date, a base, which is specific to their seating on the support surface to be fitted, and which comprises on the surface a compartment, here said simply for convenience, connection compartment, in which is capable of unblocking the necessary power cable, a socket support, which comprises a housing by which it is suitable for receiving a socket, and which, forming a separate part of the base, is adapted to be removably attached to that -this, by then closing its connection compartment, and a diffuser, which, too, is adapted to be attached to the base, around the connection compartment, by delimiting with the base the volume necessary for housing a bulb.
  • connection compartment In order to comply with the standard to be observed, access to the connection compartment must be prohibited during normal operation without the aid of a tool.
  • the socket support is reported to do this by screwing on the base, and, in practice, several screws, for example three in number, are necessary for this purpose.
  • the present invention generally relates to a provision which, on the contrary, enables this security to be satisfied in all certainty in a very simple manner.
  • a lighting porthole of the type concerned characterized in that, between the socket support and the base, there are, on the one hand, sliding mounting means, and, on the other hand apart, latching locking means.
  • the installation of the socket support is further simplified and facilitated.
  • At least one screw can possibly be used in addition, to positively block the locking means for snap-fastening implemented , and thus provide an additional guarantee.
  • this reflector when a reflector is provided, this reflector, according to a second development of the invention, covers at least partially the socket support when the latter is in place on the base, and its attachment to this base is made by at least one screw.
  • connection compartment In normal handling, the need to have a tool to access the connection compartment is reinforced, since it is first necessary to remove the reflector, and therefore unscrew the the screw securing it.
  • the lighting porthole according to the invention advantageously provides double insulation for the live parts.
  • this lighting porthole comprises a base 10, which is suitable for its seat on any support surface to be fitted, and which, according to methods described in more detail later, comprises on the surface a compartment 11, said connection compartment, in which is capable of opening the necessary power cable 12, a socket support 13, which has a housing 14 by which it is suitable for receiving a socket 15, and which, forming a separate part of the base 10, is adapted to be removably attached thereto, then closing its connection compartment 11, and a diffuser 16, which is also adapted to be attached to the base 10, around the connection compartment 11, in delimiting with this base 10 the volume necessary for housing a bulb, not shown.
  • the diffuser 16 which is translucent, if not transparent, is made of glass or of synthetic material, and, for example, it is attached to the base 10 by a mounting of the bayonet mounting type.
  • the lighting porthole according to the invention comprises, in addition, in the embodiment shown, a reflector 18, intended to be superimposed on the bottom 20 of the base 10, on at least part of the surface of this bottom 20, under the bulb used.
  • the base 10 has an external side wall 21, which is generally frustoconical, flaring backwards, and an internal side wall 22, which is also generally tapered, flaring forward.
  • connection compartment 11 is adjacent to the internal side wall 22.
  • connection compartment 11 thus opens outwards both on the front, perpendicular to the bottom 20, and laterally, parallel to this bottom 20.
  • connection compartment 11 has an upper outlet 25, level with the upper surface of the bosses 24 which delimit it, and a lateral outlet 26, formed by the free space between these bosses 24.
  • socket support 13 between the socket support 13 and the base 10 intervene, on the one hand, sliding mounting means, and, on the other hand, latching locking means.
  • the sliding mounting means comprise two slides 28, which, parallel to one another, are provided on the base 10, on either side of the connection compartment 11, and with which the socket support 13 is adapted to come into sliding engagement.
  • the slides 28 protrude from the upper surface of the bosses 24 of the base 10, with angled returns 29 directed towards one another, parallel to this upper surface, at a distance therefrom, and they are each respectively preceded by oblique engagement walls 30, which, directed towards their bottom 31, thus jointly forming a frustoconical trough, are adapted to facilitate engagement of the socket support 13 therein.
  • the socket support 13 comprises, in a dihedral, on the one hand, a sole 32, by which it is adapted to conceal the upper outlet 25 of the connection compartment 11, and, on the other hand, a dropped edge 34, by which it is adapted to conceal the lateral outlet 26 thereof.
  • the lateral sections 35 of the sole 32 are straight and parallel to each other, and, by these lateral sections 35, the socket support 13 is directly adapted to engage with the slides 28 of the base 10.
  • the sole 32 can be arched, at least at the level of its lateral edges 35, in order to make up for any mounting clearance between these lateral edges 35 and the slides 28.
  • its bending may affect it in its entirety, developing along an axis parallel to the slides 28, its middle part then being closer to the bottom 20 of the base 10 than its lateral edges 35.
  • the base 10 has, projecting from its internal side wall 22, in the connection compartment 11, generally halfway between the slides 28 , at least one rib 17, the upper edge 27 of which is chamfered for this purpose, forms a positioning ramp with which cooperates in support, at the end of the stroke, the edge of the sole 32 of the socket support 13 to reach the upper edge of this internal side wall 22.
  • two ribs 17 are thus provided, parallel to one another, at a distance from each other, from the bottom 20 of the base 10, in the connection compartment 11.
  • the housing 14 presented by the socket support 13 for receiving a socket 15 forms a projection on its sole 32, and the outlet 36 of this housing 14 partly bites on its fallen edge 34.
  • this housing 14 has at least one elastically deformable tab suitable for the snap-fastening of the socket 15.
  • socket support 13 and the base 10 intervene support and guide means, which, during the installation of the socket support 13, and as explained later, allow this socket support 13 to find pressing on the base 10 upstream of the sliding mounting means provided for its installation.
  • these support and guide means comprise, on the base 10, a boss 38, which, intermediate between the bosses 24, protrudes from the bottom 20, in the connection compartment 11, and, on the socket support 13, a partition 39, by which the latter is able to bear on this boss 38, and, more precisely, on the upper surface 40, parallel to the bottom 20, of the latter.
  • This partition 39 of the socket support 13 extends projecting on its lower surface, parallel to the lateral edges 35 of its sole 32.
  • its upper surface 40 is level with the bottom 41 of this lateral outlet 26.
  • the lateral outlet 26 of the connection compartment 11 is preceded by an oblique engagement wall 42 which joins its level, and, more precisely, that of its bottom 41, in continuity with the upper surface 40 of boss 38.
  • this oblique engagement wall 42 extends along a bottom rope 20, over the entire length of this rope, connecting the two bosses 24 to each other, and, along its opposite edge. to these bosses 24, it is connected to the bottom 20 by a straight wall 43 perpendicular thereto.
  • the latching locking means intervening between the socket support 13 and the base 10 generally comprise, on any of the elements that constitute this socket support 13 and this base 10, at least an elastically deformable tongue 45 and, on the other of these elements, a retaining notch 46 with which this elastically deformable tongue 45 is intended to cooperate in abutment.
  • a single elastically deformable tongue 45 is provided, and it equips the socket support 13.
  • the elastically deformable tongue 45 extends in overhang from the free edge of the fallen edge 34 of the socket support 13, forming with this dropped edge 34 a dihedral of opposite orientation to that which it shape with sole 32.
  • the elastically deformable tongue 45 is thus able to be superposed on this oblique engagement wall 42, on a portion of the latter.
  • the single elastically deformable tongue 45 thus implemented is eccentric with respect to the central region of the socket support 13 intermediate between the slides 28, being offset towards one of them.
  • the retaining catch 46 is formed by a rib which, projecting from the oblique engagement wall 42 of the base 10, borders locally the edge thereof opposite the connection compartment 11, in continuity with the wall right 43.
  • this retaining notch 46 is straight.
  • notch 48 which, suitable for the insertion of any tool, for example the blade of a screwdriver, makes it possible to act on the tongue elastically deformable 45, on the lower surface thereof, when this elastically deformable tongue 45 is engaged with it.
  • a rib 47 extends in square with respect to this retaining notch, by connecting it to the oblique engagement wall 42, to form a lateral stop for the elastically deformable tongue 45 and thus oppose any possible warping of the socket support 13, c that is to say, any rotation on itself of this socket support 13 about an axis perpendicular to its sole 32 within the limits of the possible mounting clearance authorized in such a direction by the slides 28.
  • the elastically deformable tongue 45 has, in its central zone, a bore 50, for the implementation of a screw 51 intended to cooperate in screwing with a bore 52, which, provided in correspondence with this effect on the oblique engagement wall 42 of the base 10, extends in favor of a well 53 projecting from the lower surface thereof.
  • the reflector 18 has a circular edge 55, at the contour of the internal side wall 22 of the base 10, and a straight edge 56, which, like the oblique engagement wall 42 of the latter ci, generally extends along a cord.
  • This straight edge 56 has a notch 57 in its central zone, for its engagement under the sleeve 15.
  • the reflector 18 is fixed to the base 10 by at least one screw 60.
