A support frame for a dropped ceiling includes a plurality of elongated primary rails disposed substantially parallel to one another, with a plurality of elongated secondary rails disposed parallel to one another and transversely between a pair of primary rails to form a grid system. A ceiling panel is positioned with its edges supported on a pair of primary and secondary rails to form the dropped ceiling. Each primary rail includes an elongated generally inverted U-shaped support member connected to an upper face thereof to support and suspend the primary rails. Each secondary rail includes an elongated ridge with projecting ends connected to the primary rail support member to support the secondary rail from the primary rail support members. An insert extends the length of the primary rail and has a lower edge slidably engaged in a slot in the primary rail upper face, to support the primary rail therefrom. The insert is journaled between the legs of the primary rail support member and secured with fasteners.

DETAILED DESCRIPTION It is therefore a general object of the present invention to provide an improved dropped ceiling support frame with exposed wood members for supporting the ceiling panels.
Another object is to provide a dropped ceiling support frame which is easily adjustable to accept various sizes of ceiling panels.
A further object of the present invention is to provide a dropped ceiling support frame which is economical to manufacture and refined in appearance.
These and other objects of the present invention will be apparent to those skilled in the art.
