Definitions

  • the present invention relates to a panel for a grid ceiling.
  • a panel for a grid ceiling said panel comprising first and second metal panel members of U - or V-shaped cross-section, formed with side flanges and with the closed end of the cross-section of each of said panel members facing downwardly and with the first panel members being arranged parallel to one another and the second panel members also being parallel to one another, but perpendicular to the first panel members to form rectangular cells therebetween, the side flanges of the first panel members each being formed with slots extending from the free edges of the side flanges to a point spaced from the closed end of the cross-section and with an aperture on at least one of said flanges between said point and the closed end of the cross-section, the flanges of the second panel members each being formed with a cooperating slot extending from the closed end of the cross-section to a location spaced from the free edge of that flange, the slots of the second panel members being shaped to interfit with the slots of the first panel members at the cross-over
  • Such a construction has the lugs of the second panel engaged with the apertures of the first panel at a location close to the closed ends of the cross-section, that is close to the lower surface of the grid ceiling at the cross-over points. It has been found that this can provide a simple way of forming a good rigid connection at the cross-over points.
  • each of the flanges of the first panel is formed at the vicinity of each slot, with an aperture between said point and the closed end of the cross-section and each of the edges of each slot of the second panel member is formed with a lug extending inwardly of the slot, whereby, when the panel members are interfitted, the thus formed four lugs each engage a separate end of an aperture 6f the first panel member.
  • the closed ends of the slots may be provided with a guide tongue which fits snugly within the space between the flanges of the other panel and the free ends of these guide tongues are preferably smoothly curved to facilitate insertion and also to facilitate the formation of the tool used to punch out the panel members.
  • At least one flange of each second panel is provided with an opening between said location and the free edge of the flange, at least one side of each slot of the first panel member having a further lug extending inwardly of the slot at a position to engage lockingly in the opening of the first panel member.
  • each flange of the second panel is formed, in order to provide even greater rigidity, at the vicinity of each slot, with an opening between said location and the free edge of the flange and each of the edges of each slot of the first panel member is formed with a further lug extending inwardly of the slot, whereby, when the panels are interfitted, the thus formed four further lugs engage in a seperate end of an opening of the second panel member.
  • first panel member 10 and a second panel member 12 each of identical cross-section formed of generally U shaped cross-section metal, in fact being channel shaped having a web 14 joining two parallel side flanges 16, 18 provided with inturned rims 20, 22.
  • the first panel 10 is provided from the free edge defined by the rims 20, 22 with a slot 24 having side edges 26, 28, the slot terminating at a point 25 spaced from the web 14.
  • a guide tongue 30 having a smooth curved upper surface 32.
  • an aperture 34 of rectangular cross-section having ends 36, 38.
  • the flanges 16, 18 of the second panel member 12 are each provided with a cooperating slot 40 having a closed end 42 with a guide tongue 44 again having a rounded free end 46.
  • the side edges 47, 49 of the slot 40 are formed with lugs 48, 50 respectively these being of triangular cross-section having a lower surface inclined to these edges at an acute angle and upper surfaces substantially perpendicular to the edges 47, 49.
  • the panels 30, 44 will pass within the space between the flanges of the other panel and upon further downward movement the lugs 48, 50 will engage in the apertures 34 with a snap-fit action and abut against the ends 36, 38 of these apertures thereby providing a very rigid interconection of the panel members adjacent the webs 14 thereof.
  • the second panel members 12 are additionally provided, between the location 42 of the closed end of the slot 40, with a generally rectangular opening 50 having, adjacent the end thereof, recesses 52, 54.
  • the panels 12 are generally similar to those of Figure 1, but the edges 26, 28 of the slots 24 are formed with further lugs 58, 56 respectively of generally similar shape to the lugs 48, 50.
  • the slots 40 also remove a portion of the web 14 of the channel section of the second panel members, these produce an inherent weakness in the second panel members at the points of intersection.
