Definitions

  • the present invention relates generally to luminaires of the type comprising a base, and, attached to the latter, a cover translucent, which, most often made of glass, is commonly called a jar.
  • the base of these lights is almost necessarily made in one material of a different nature from the material constituting the translucent cover.
  • this base is metallic.
  • the translucent cover is attached to the base by screws.
  • This border which could only intervene occasionally, forms the more often in practice a frame at the periphery of the translucent cover.
  • the hinge intervening between the base and this border usually comprises two pivoting elements engaged in swiveling one with the other, one secured to the base, the other secured to the border.
  • the translucent cover is itself permanently hinged to the base, without being able to be disassociated from it.
  • the present invention generally relates to a provision to avoid this drawback.
  • the translucent cover can itself be detached from the base, and, moreover, it can if desired be considered to deliver the luminaire with the cover translucent effectively separated from the base.
  • the installation of the luminaire is advantageously facilitated, the fixing of the base to any support and the operations to be carried out on this base after this fixing can indeed be ensured in the absence of the translucent cover, and, therefore, without the discomfort that it is likely to cause.
  • the cover translucent can advantageously remain attached to the base after its opening, by the hinges of its border, only being removed the screws or other securing means ensuring its attachment to this base.
  • the layout according to the invention also advantageously leads to independence between the articulation and fixing functions thus intervening between the cover translucent and the base, for a safer control of tightness possibly required between them.
  • the luminaire 10 which is, for example, an autonomous block emergency lighting, comprises, overall, a base 11, by which it is adapted to be attached to any support, for example a wall 12, Figures 7 and 8, or a ceiling 13, Figure 10, and, duly attached to this base 11, according to arrangements described in more detail later, a cover translucent 14.
  • This base 11 and this translucent cover 14 have both basically a shell shape, and they face each other next substantially a plan.
  • the base 11 has, in hollow on its edge 15, a groove 16, which runs in continuous throughout its outlet, and that, in correspondence, the hood translucent 14 has, projecting from its edge 18, a lip 19 suitable for engage in the groove 16 of the base 11.
  • the edge 15 of the base 11 is formed by a flange 20 which this base 11 has projecting outwards along its periphery, and, in correspondence, the edge 18 of the translucent cover 14 is itself formed by a flange 21 that this translucent cover 14 also has an outward projection while along its periphery.
  • sealing means are corollarily provided between the base 11 and the translucent cover 14.
  • these means sealing comprises a seal 22, which, present in the groove 16 of the base 11, is crushed by the lip 19 of the translucent cover 14 when this cover translucent 14 is applied by its edge 18 against the edge 15 of this base 11.
  • the base 11 and the translucent cover 14 thus define jointly an enclosure in which intervene, duly carried by the base 11, on the one hand, any lighting member 24, and, for example, a fluorescent tube, as shown in broken lines in Figures 7, 8 and 10, and, on the other hand, the organs necessary to support and serve this lighting member 24.
  • the materials constituting the base 11 and the cover translucent 14 are of different natures.
  • the base 11 is made of metal while the cover translucent 14 is made of glass.
  • the translucent cover 14 is articulated to the base 11 by means of an edge 26, which is connected to the base 11 by at least one hinge 28, and of which it is integral.
  • the border 26 forms a frame at the periphery of the translucent cover 14, according to the arrangements described in more detail later, and the luminaire 10 comprises two hinges 28, which, arranged in opposite positions with respect to each other, are aligned one with the other along the same axis of articulation A.
  • This articulation axis A is shown diagrammatically in broken lines on the Figures 1 and 5, and it is marked by its trace in Figure 2.
  • the two hinges 28 each intervene respectively at the two ends of the same side of the rectangular outline common to the base 11 and to the translucent cover 14.
  • the two hinges 28 are of identical constitution.
  • pivoting elements 30, 31 in swiveling engagement with each other, namely, a pivoting member 30 secured to the base 11 and a pivot element 31 secured to the border 26.
  • the pivoting element 31 secured to the border 26 belongs to an elastically deformable tab 32, so that, by elastic deformation thereof, it can be detached from the element of pivoting 30 secured to the base 11.
  • the pivot element 30 integral with the base 11 is a pin which projects laterally in door to false on this base 11, and, more precisely, on the edge of the rim 20 of this, and, jointly, the pivoting element 31 secured to the edge 26 is a hole provided for this purpose on the elastically deformable tab 32 of this border 26.
  • the pin forming the pivoting element 30 integral with the base 11 comprises a barrel 33 of diameter D1 and a head 34 of diameter D2 greater than that D1 of the barrel 33.
  • the hole forming the pivot element 31 integral with the border 26 is a buttonhole, that is to say a hole globally elongated, the width L of which is intermediate between the diameter D1 of the barrel 33 of the journal forming the pivoting element 30 integral with the base 11 and the diameter D2 of the head 34 of this pin, and which, locally, and, by example, substantially halfway between its ends, presents a widening 35 proper to the passage of the latter.
  • This widening 35 which transversely extends globally on either side of the buttonhole that it affects, has, therefore, overall, a circular outline, of diameter D3 greater than the diameter D2 of the head 34 of the pin forming the pivoting element 30 integral with the base 11.
  • the enlargement 35 intervenes at a distance from both ends of the hole forming the pivoting element 31, and, for example, midway between these ends.
  • the drilling forming this pivot element 31 is elongated substantially perpendicular to the edge 18 of the translucent cover 14.
  • At least of the ends of this hole which is the most remote from the edge 18 of the translucent cover 14 has a rounded contour in semicircle, to be able to cooperate in pivoting with the pin forming the pivoting element 30 integral with the base 11.
  • both of the ends of the bore forming the pivoting element 31 integral with the border 26 have a rounded semicircle outline.
  • the border 26, which, in plan, has a rectangular outline like that common to the base 11 and the cover translucent 14, has, at right angles, two wings 36, 37, namely, on the one hand, a first wing 36, which extends substantially parallel to the following plane which confront the base 11 and the translucent cover 14, and by which it is applied to one of the faces of the rim 21 of the translucent cover 14, in this case that of the faces of this rim 21 which is furthest from the base 11, and, on the other hand, at the outer periphery of the first wing 36, a second wing 37, by which it extends slightly beyond the edge edge rim 21 of the cover translucent 14.
  • the edge 26 is secured by gluing to the translucent cover 14, and, more precisely, to the rim 21 thereof.
  • the border 26 comprises, locally, at least one crimping tongue 38, which, extending its second wing 37, is engaged, by folding 90 °, under the other face of the rim 21 of the translucent cover 14, that is to say under that of the faces of this rim 21 which is closest to the base 11, by means of a recess 49 of this face.
  • crimping tabs 38 are planned, from place to place.
  • these elastically deformable legs 32 are each in one piece with the second wing 37 of the border 26, forming a extension thereof.
  • indexing means 39 intervene.
  • indexing means 39 comprise, on each of the elastically deformable legs 32 of the border 26, at least one rib 40, which projects from the side of the base 11, and which is able to cooperate in abutment with the edge 15 thereof.
  • a rib 40 extends over each of the elastically deformable legs 32.
  • this rib 40 extends substantially perpendicular to the edge 18 of the translucent cover 14, of the side of that of the ends of the hole forming the pivoting element 31 which is furthest from this bracket 18.
  • the rib 40 is formed by a simple local deformation, in half-wave, of this elastically deformable tab 32.
  • the indexing means 39 also include, projecting from the base 11, and, more precisely, protruding from its edge 20, a flat boss 41 which locally widens its edge 15.
  • the border 26 preferably presents at the right of each of the holes 43 of the translucent cover 14, an ear 45, which comes from a integral with its first wing 36, and which, interposed between the rim 21 of the translucent cover 14 and the corresponding screw head 42, allows advantageously spare this translucent cover 14 during the screwing of this screw 42.
  • the translucent cover 14 is attached to the base 11, by engagement of holes constituting its pivoting elements 31 on the pins of the base 11 constituting the pivot elements 30 thereof, in favor of widening 35 of these holes.
  • the translucent cover 14 is then moved away from the base 11, until that the holes forming its pivoting elements 31 come into abutment against the pins forming the pivoting elements 30 of this base 11 by that of their ends which is furthest from the edge 18 of the cover translucent 14.
  • the translucent cover 14 can be pivoted 90 ° downwards, then abandoned.
  • the translucent cover 14 keeps itself square with the base 11, despite the dangling of which it is the object, this rib 40 coming cooperate in abutment with the edge 15 of the base 11, in favor of the flat boss 41 locally enlarging it, as shown in FIG. 9.
  • the translucent cover 14 can, in any case, be detached from the base 11.
  • the translucent cover 14 of the following luminaire 10 the invention can advantageously have, before any pivoting, a movement initial translational clearance, parallel to itself, relative to the base 11, when, to be opened, it is moved away from this base 11, and, likewise, it can advantageously have a final movement of engagement in translation, when, to be closed, it is brought closer to the base 11.
  • Such translational movement is particularly favorable when, as in this case, a seal 22 being present, a function sealing is preferably to be provided between the translucent cover 14 and the base 11.
