Definitions

  • the present invention relates to luminaires and, in particular, to luminaries having a reflector of adjustable focal length including two curved portions. Such a reflector is described in
  • WO 96/37732 (which has the same inventor as the present application) and will hereafter be termed a doubly arched reflector.
  • each reflector is a U-shaped trough of fixed dimensions.
  • a number of such troughs can be connected with their longitudinal axes aligned to extend along the full length of the fluorescent tube.
  • Such aligned troughs can be connected together by a mushroom shaped male coupling element 9 which is received directly, and without lateral translation, into a circular hole 10 which forms the other coupling element.
  • the two elements 9, 10 inter-engage because the hole 10 has an undercut graded diameter of circular shape.
  • the genesis of the present invention is a desire to provide an arrangement whereby such a luminaire can be assembled in a more convenient fashion.
  • an assembly comprising a reflector (101) of a doubly arched luminaire (100) and a locating mechanism for a pair of reflector sheets from which the reflector is assembled, characterized in that said assembly comprises at least one mushroom-shaped stud on one of said sheets and a corresponding keyhole shaped aperture on the other of said sheets, said stud comprising a stalk and a cap and said aperture comprising a main opening and a smaller extension wherein each said stud and aperture are dimensioned so that said cap can pass through said main opening but not said extension and said stalk can be retained in said extension with a friction fit.
  • the reflector 1 of the prior art is formed from two sheets 2 preferably of resilient metal construction which are joined together about a spine 3 in the manner of the pages of a book.
  • a tensioning device in the form of a chain 4 and hooks 5 is used to provide the desired adjustment of the focal length of the reflector 1.
  • the remaining components of the luminaire are essentially a lamp socket mounting 12 which supports the lamp socket 18 which in turn supports the lamp 20. If desired, a heat shield 17 having perforations 30 can be provided.
  • the luminaire 100 of the preferred embodiment is illustrated having a reflector 101 formed from two sheets 102 and 122 essentially as before with a lamp socket mounting 112 and a pair of tensioning filaments 104 (only one of which is illustrated in Fig. 2 ).
  • the sheets 102, 122 are supplied in a compact knock down form stacked one above the other and are then joined together to form a spine 103.
  • the sheet 122 is provided with a pair of generally mushroom shaped lugs 107 which each have a central cylindrical stalk 108 and a substantially flat cap 109.
  • the reflector sheet 102 is provided with a pair of keyhole apertures 127 each of which has a central opening 128 and a narrow extension 129 extending therefrom. The extensions 129 are substantially parallel.
  • the portions of the sheets 102, 122 which are joined together to form the spine 103 each include four holes 111.
  • the caps 109 of the lugs 107 are passed through the central openings 128 of the corresponding keyhole apertures 127. This generally locates the two sheets 102, 122 in the correct orientation and configuration. Then the sheets 102, 122 are moved relative to each other in the direction of the spine 103 so as to engage the stalks 108 with the corresponding extensions 129. This results in a friction fit between the lugs 107 and the keyhole apertures 127. The friction fit may be between the stalk 108 and the extension 129, or between the underside of the caps 109 and the surface of the sheets 102, 122, or both.

Claims (6)

  1. Ensemble comprenant un réflecteur (101) d'un luminaire doublement arqué (100), le réflecteur comprenant une paire de feuilles de réflecteur et un mécanisme de positionnement pour la paire de feuilles de réflecteur (102) à partir desquelles le réflecteur (101) est assemblé, ledit ensemble comprend au moins un téton (107) en forme de champignon sur l'une desdites feuilles et une ouverture (127) en forme de trou de serrure correspondante sur l'autre des dites feuilles, ledit téton comprenant une tige (108) et un sommet (109) et ladite ouverture comprenant une ouverture principale (128) et une extension plus petite (129), dans lequel chaque dit téton et chaque dite ouverture sont dimensionnés de telle sorte que ledit sommet puisse passer à travers ladite ouverture principale mais pas à travers ladite extension et que ladite tige puisse être retenue dans ladite extension par ajustement par frottement.
  2. Ensemble selon la revendication 1, dans lequel une desdites feuilles de réflecteur est pourvue d'une pluralité de tétons en forme de champignon (107) espacés les uns par rapport aux autres et l'autre desdites feuilles de réflecteur est de même pourvue d'une pluralité d'ouvertures en forme de trou de serrure (127) pareillement espacées, les extensions plus petites (129) desdites ouvertures étant essentiellement parallèles et pareillement alignées.
  3. Ensemble selon la revendication 1 ou 2, dans lequel ledit ajustement par frottement se fait entre ladite extension (129) et ladite tige (108).
  4. Ensemble selon la revendication 1 ou 2, dans lequel ledit ajustement par frottement se fait entre la surface dudit réflecteur (102) adjacente à ladite extension et ledit sommet (109).
  5. Ensemble selon la revendication 1 ou 2, dans lequel ledit ajustement par frottement se fait entre ladite extension (129) et ladite tige (108) et entre les surfaces dudit réflecteur (102) adjacentes à ladite extension et ledit sommet.
  6. Luminaire incorporant l'ensemble selon l'une quelconque des revendications 1-5.
