An improved ceiling panel for use in concealed suspension is disclosed which includes framing a panel body member on the sides and rear face thereof in a manner that the lower surface of the panel is determined by the metal framing members. These members are preferrably extruded aluminum and hence the accuracy thereof and hence the accuracy of the lower surface of the panel can be maintained in a closer tolerance range. In addition the framing members include an inwardly directed flange which preferrably is held by an adhesive within an appropriately located kerfed recess in the edge of the body member. This structure serves to stiffen the panel and reduce deflection thereby providing a ceiling system of substantially improved quality. Height variations in ceiling systems are easily recognized and the present disclosure teaches a system of high quality while providing a system which is easy to install and has the advantages of ready access to the area above the ceiling.
A ceiling panel for use in a suspended ceiling system to define an essentially horizontal ceiling surface, said ceiling panel comprising a body member of acoustical dampening material have at least one essentially planar surface, said body member having straight side edges generally perpendicular to said planar surface which define the ceiling panel periphery, generally "L" frame members secured to the side edges of said body member to overlie a portion of a top surface of said panel and abutting the side edges thereof, each of said frame members including an inwardly directed planar projection snuggly received within a kerf provided in the side edge of said body member, said frame member being bonded to said body member by an adhesive whereby said frame member when secured to a body member cooperates with said body member to stiffen said panel.
A ceiling panel for use in a suspended ceiling system to define an essentially horizontal ceiling surface, said ceiling panel comprising a rectilinear flat body member having a periphery and a thickness between about half an inch to two inches, a plurality of extruded aluminium members applied about the periphery of said body member, said body member being kerfed about the periphery intermediate top and bottom surfaces of the panel to define a recess generally parallel to the bottom surface of the body member, each extruded aluminium member having a first arm and a second arm secured to form a right angle, said first arm including a thin inwardly directed flange means generally parallel to said second arm, whereby said members when applied to the periphery of said body member are secured thereto by an adhesive securing said flange within said kerf in a manner such that said first arm is in engagement with the periphery of the body member and the second arm overlies and is in contact with the top surface of the body member about the periphery thereof.
A suspended ceiling system comprising a plurality of grid support members, a plurality of ceiling panels having a body member and a reinforcing edge secured about the panel and overlying a top edge of the panel and extending down a side edge thereof, spring means hingedly secured to each of said panels and releasably secured to one of said grid members, wherein said spring means maintains said panel in position against said grid members in one position and in a second position said spring means is selectively disengagable for suspending a ceiling panel generally perpendicular to said grid members, said reinforcing edge including a thin inwardly directed flange means generally parallel to a top surface of the panel received within a kerfed recess in the edge of said body member, said reinforcing edge being secured to said body member by an adhesive securing said flange means and said body member within the kerfed recess.
A suspended ceiling system comprising a plurality of ceiling panels and a plurality of structural members arranged in a grid-like manner to cooperatively support and accurately position said ceiling panels, said panels including a body member having a lower planar surface and a reinforcing edge means which accurately defines side edges and an upper peripheral edge of each of said panels, each panel being faced with a sheet material which extends across the lower planar surface of said body member and is secured to the side edges of said panel, said structural members having upper and lower portions with said lower portion having a flange and a downwardly extending alignment stud generally centered with respect to said flange, securement means associated with said reinforcing edge member and the upper portion of said structural members for fastening said panels in place beneath said structural members, said edge means cooperating with said alignment stud to align the side edges of adjacent panels and said flange cooperating with said reinforcing edge means to position the panels beneath the grid members a predetermined distance, said reinforcing edge means including an inwardly directed flange received in a kerfed recess in the edge of said body member, said flange being in secured engagement with said kerfed recess to thereby secure said reinforcing edge means to said body member.
In a suspended ceiling grid support network for supporting and accurately positioning ceiling panels, the network being defined by a plurality of structural members having a top flange, a perpendicular web and a lower flange, said structural members being interconnected by junction members to define the grid network, an improved junction member comprising a top member for at least partially overlying the top flange of structural members, a lower body member having a plurality of stop faces extending generally downwardly from and perpendicular to said top member, each of said stop faces haiving a pair of parallel arms perpendicular to said planar top member and spaced downwardly from said planar member a distance to allow a top flange of a structural member to be snuggly received therebetween, said arms being relatively spaced to snuggly receive the web of a structural member, said top member including detent means associated with each of said pairs or arms which cooperate with a structural member to positively secure such structural member in said junction member when slidably inserted between a pair of arms and said top member.
In a suspended ceiling grid network for supporting and accurately positioning ceiling panels, the network being defined by a plurality of structural members each having a top flange, a central perpendicular web and a lower flange parallel to said top flange, and interconnected and supported by junction members, each junction member comprising a top planar surface for overlying at least a portion of the top flanges of structural members and a body portion for receiving at least the web of a structural member to determine the lateral position thereof and to urge the upper flange into abutment with the top planar surface thereby accurately fixing each structural member received within a junction member and means for locking such structural members slidably received in said junction members whereby proper positioning of junction members beneath the support steel accurately determines the elevation and position of the structural members supported by such junction members.
A suspended ceiling system comprising a grid network of support members and a plurality of ceiling panels individually supported below said grid network,
