Abstract
Description
- The present invention relates to a panel for a grid ceiling.
- Many forms of panel for grid ceilings have been proposed and these often involve the use of generally hollow metal members of U or V-shaped or channel cross-section formed with side flanges and slots are cut out of the upper part of the side flanges of one set of parallel members and out of the lower part of the flanges of the other set of parallel members to enable the panels to be interfitted at the points of intersection of the grid. While it is known to provide lugs to engage in apertures or openings in the other panel at a cross-over point, this does not provide an entirely satisfactory arrangement in which the interconnection between the panels is fully rigid.
- It is now proposed, according to the present invention, to provide 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 points of the grid ceiling, with the closed end of the first and second panel members then in substantially the same plane and at least one side of each slot of the second panel having a lug extending inwardly of the slot at a position to engage lockingly in the aperture of the first panel.
- 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.
- Preferably 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.
- It will be appreciated that this latter arrangement ensures an even more rigid interconnection of the panels adjacent the lower surface of the grid ceiling.
- To facilitate insertion, at the cress-over points, 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.
- Advantageously, 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. In this way not only is the connection rigid adjacent the lower surface of the grid ceiling but an even greater rigidity can be provided by the spaced apart cooperation between the lugs of the second panel and the apertures of the first on the one hand and the further lugs of the first panel and openings of the second on the other hand.
- Preferably 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.
- In order that the present invention may more readily be understood,the following description is given merely by way of example, reference being made to the accompanying drawing in which:-
- Figure 1 is a perspective exploded view showing schematically the first and second panel members of one form of panel for a grid ceiling according to the invention; and
- Figure 2 is a similar view of a second embodiment.
- Referring first to Figure 1 there are shown a 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 aweb 14 joining twoparallel side flanges rims rims slot 24 havingside edges point 25 spaced from theweb 14. At the closed end of theslots 24 there is provided aguide tongue 30 having a smooth curvedupper surface 32. At a position between thepoint 25 and theweb 14 there is provided anaperture 34 of rectangular cross-section havingends - The
flanges second panel member 12 are each provided with a cooperatingslot 40 having a closedend 42 with aguide tongue 44 again having a roundedfree end 46. Theside edges slot 40 are formed withlugs edges - When the
second panel member 12 is moved downwardly relative to the first panel member 10 and theslots panels lugs apertures 34 with a snap-fit action and abut against theends webs 14 thereof. - The construction of Figure 2 is very similar and like parts have been indicated by like reference numerals.
- The
second panel members 12 are additionally provided, between thelocation 42 of the closed end of theslot 40, with a generallyrectangular opening 50 having, adjacent the end thereof,recesses - The
panels 12 are generally similar to those of Figure 1, but theedges slots 24 are formed with further lugs 58, 56 respectively of generally similar shape to thelugs - When these panels are interfitted, in addition to the
lugs ends slots 34, the further lugs 56, 58 engage in theopenings 50 and in particular in therecesses - Because the
slots 40 also remove a portion of theweb 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. Thelugs apertures 34, and preferably abutting theends
