  • CEILING MODULES WITH LAMP HOUSINGS BACKGROUND OF THE INVENTION This invention relates to ceiling modules and in particular to a new ceiling module construction.
  • the use of ceiling modules, as disclosed and described more fully in Quin and Garnett, US. Pat. No. 3,372,270 (Mar. 5, 1968) to provide fully engineered environmental control through a highly flexible ceiling system has revolutionized attitudes toward the function and nature of ceiling components.
  • the use of ceiling modules (that is, ceiling components of substantial size in the range of about 16 square feet to about 36 square feet) as repeating ceiling components to provide not only a ceiling-defining area, but also lighting and other environmental control elements such as air distribution, sound control and spatial division elements has allowed an unparalleled freedom in providing truly effective and attractive environmental control.
  • the use of ceiling modules has also simplified the effectuation of each type of environmental control, and has provided these elements in an easily installed package.
  • One of the objects of this invention is to provide an improved ceiling module which may be either flat or pyramidal and which is extremely rigid.
  • Another object is to provide such a module having a frame which may be made of relatively light gauge metal and which may have ceiling-defining panels which are made of light gauge metal or of other materials.
  • Another object is to provide such a module which is easily and inexpensively assembled.

  • the framework includes four identical elongate broadfaced sheet metal beams, each being bent to form a central lamp housing part, a spine part at one end and an attachment part at the other end, each of the spine part and attachment part being bent outwardly from the lamp housing part to form an angle of with the lamp housing part.
  • These four beams are arranged to form a square lamp housing defined by the broad faces of the lamp housing parts, with the attachment part of each beam secured in face-to-face relation with a spine part of a contiguous beam, to form four diagonally outwardly extending spines.
  • the beams are secured to each other by deforming the material of one of the beams through an opening in the contiguous beam.
  • flanges on the edges of four trapezoidal panels are secured to each other and to the spine by a frictional fit between alternately offset fingers along the lower edges of the spines and by the deformation of the flange material through openings in the lapped fingers and panel flanges.
  • the outer edge of the panels form a rectangle and the inner edges form a central open seat for a closure member such as a lighting panel.
  • the central seat has vertical sides and the closure member mounted in the seat is supported by the framework.
  • the four diagonally outwardly extending spines are stiffened by a peripheral trim rail made up of four pieces, each of which extends along one edge of the module and includes at its end bent ear parts which are secured to the spines in face-to-face relation.

  • six extruded holes 33 are provided for attaching the spine part 11 to the attachment part 15 of a contiguous beam 3, as explained more fully hereinafter.
  • the lamp housing part 13 of the beam 3 includes a broad face 35 having struck from it an inwardly and downwardly extending light baffle flap 37.
  • the flap 37 also acts as a stop for a turned flange on the short base of the trapezoidal panel 5.
  • the flap 37 is provided with a small upwardly offset tab 38 for interlocking the corners of adjacent flaps 37.
  • the broad face 35 of the lamp housing part 13 is deformed outwardly to form a stiffener 39.
  • a lower flange 53 on the lamp housing part 13 further stiffens this part of the beam.

  • knock-outs 41 are provided for wiring through each of the four beams 3, although generally those in only one beam will be used.
  • lanced slots 43 of two parallel opposed lamp housing parts 13 may be used for holding a closure element on the top plate 9.

  • the framework may then be secured to the panels by placing the spines over the lines of contiguity of the panels 5, with lapped flanges 61 held in the spring clips formed by the fingers 31 and 55 and with the flanges 63 and lips 65 trapped by the broad faces 35 of the lamp housing parts 13 and by the light baffle flaps 37.
  • the panels are then permanently secured to the spine parts by the use of standard fasteners or, preferably, by lancing a three sided cut through the fingers 31 and lapped flanges 61 and bending all three layers of material at right angles to the plane of the lapped flanges to form a locking tab.

  • An inwardly struck tab 77 engages the flange 59 on the long base of a panel 5.
  • Holes 79 are also provided in the riser part 69 for conventional fasteners such as screws or rivets. The use of the tabs 77 minimizes the number of such conventional fasteners required.
  • Openings 81 in the upper flange 73 are provided for mounting closure strips and the like above the channel defined by the trim rails 7 of adjacent modules in a completed ceiling.
  • an ear 83 is bent in the flange 73 for securement of the trim rail to an adjacent spine part.
