Concealed grid ceiling panel system

DETAILED DESCRIPTION A ceiling system, according to an aspect of the present invention, comprises ceiling panels designed to abut adjacent ceiling panels and collectively define a concealed grid ceiling panel system.
A `T` bar grid system, of a type used in `T` bar ceiling panel systems used to support ceiling panels above a lower edge of the grid system, is used for defining the grid system for the panels of the concealed grid ceiling system.
Panel suspension clip members are secured at top edges of the `T` bar grid system and extend to at least one side of the respective `T` bar member and engage a torsion spring to the side of the respective `T` bar member.
The torsion spring and a lower edge thereof engages a ceiling panel edge and positively supports the ceiling panel beneath the grid.
Each ceiling panel includes at least two torsion springs which cooperate to support the ceiling panel immediately beneath the grid, with the top edge of the ceiling panel engaging the lower flanges of the grid system.
Preferably, each ceiling panel is supported by four torsion springs located adjacent the corners of the panels.
It is also possible to use the arrangement, but not fully conceal the grid network.
In this case, panels still contact the bottom flange of the grid network and all panels do not necessarily abut, thereby exposing a reduced portion of the lower flange of the `T` bar members.
According to a preferred aspect of the invention, alignment means are secured at a desired position, preferably centrally on the lower flange of the `T` bar members, and this alignment means cooperates with the edges of the panel to align the ceiling panels with the grid network.
According to a further preferred aspect of the invention, the panel suspension clip members are combined, such that each panel suspension clip member receives a torsion spring of abutting opposed panels positioned either side of the `T` bar member of the grid network.
According to yet a further aspect of the invention, the panel suspension clip members are located at the junctions of the grid network and opposed clip members are combined
