  • Modular ceiling system
    Patent number: 4043689
    Abstract: A modular ceiling system utilizing a plurality of stringers interlocked with one another to provide a high strength, non-warping suspended ceiling grid assembly. The T-shaped stringer employed in the grid assembly has a channel-shaped T-head designed to support acoustical ceiling tiles flush with the lower edge of the stringers. The main stringers are arranged parallel to one another and interlocked to secondary stringers to provide a grid of four sided cells. Part of the secondary stringers have the same length as one side of a single cell and others are of double that length. The double length secondary stringers are constructed to have a snug snap-lock joint with the main stringers whereas the single length secondary stringers have a snug, non-locking fit between the mid-portions of the double length stringers.

  • Modular ceiling system
    Patent number: 3949533
    Abstract: A modular ceiling system utilizing a plurality of stringers interlocked with one another to provide a rectangularly celled, high strength, non-warping suspended ceiling grid assembly. The T-shaped extruded aluminum stringer employed in the grid assembly has a channel-shaped T-head designed to support acoustical ceiling tiles flush with the lower edge of the stringers. The main stringers are arranged parallel to one another and interlocked to secondary stringers to provide a grid of four sided cells. Part of the secondary stringers have the same length as one side of a single cell and others are of double that length. The double length secondary stringers are constructed to have a snug snap-lock joint with the main stringers whereas the single length secondary stringers have a snug, non-locking fit between the mid-portions of the double length stringers.
