Abstract
Abstract A linear panel wall and ceiling system is disclosed which provides a carrier strip which can be coiled in long lengths for storage and shipment. Such carrier strip provides longitudinally aligned and relatively closely spaced, narrow slots extending along the length of the carrier strip to provide a hinge line which divides the carrier strip into a mounting portion and a support portion. The support portion is provided with laterally extending projections at intervals along its length which are proportioned to connect with and support generally U-shaped linear pans which extend perpendicular to the carrier. At the time of installation, pieces of the carrier strip are cut from the coil and installed. In instances in which the mounting portion is mounted along a plane perpendicular to the support portion, the carrier strip may be bent along the hinge line either prior to the actual mounting or after mounting. Because continuous strips can be mounted for the full span of the wall or ceiling, the pan mounting projections are automatically spaced at proper intervals along the entire length of the carrier strip and scrap is virtually eliminated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A linear system for linear walls and ceilings comprising an elongated metal carrier providing a plurality of longitudinally aligned spaced slots dividing said strip into a mounting portion and a support portion, said strip being laterally flat, the material of said strip between said slots providing hinge means, said hinge means operating to cause said strip to sharply bend along a predetermined hinge line extending lengthwise of said strip between said support portion and said mounting portion when lateral bending forces are applied between said mounting portion and said support portion to cause mounting portions and support portions to extend along planes angulated relative to each other and intersecting at said hinge means, said support portion providing a plurality of spaced laterally extending projections, and U-shaped linear pans connected to and supported by said projections, said projections being symmetrically positioned with respect to every other of said slots, the portions of said carrier between said projections being notched to a location spaced from said slots to provide said projections, said notches being substantially aligned with the remaining of said slots, said support portion providing an uninterrupted longitudinal part which cooperates with said mounting portion after said bending along said hinge line to maintain said carriers straight.
Claim 2
Dependent Claim
206 words
A linear system for linear walls and ceilings comprising an elongated metal carrier providing a plurality of longitudinally aligned spaced slots dividing said strip into a mounting portion and a support portion, said strip being laterally flat, the material of said strip between said slots providing hinge means, said hinge means operating to cause said strip to sharply bend along a predetermined hinge line extending lengthwise of said strip between said support portion and said mounting portion when lateral bending forces are applied between said mounting portion and said support portion to cause mounting portions and support portions to extend along planes angulated relative to each other and intersecting at said hinge means, said support portion providing a plurality of spaced laterally extending projections, and U-shaped linear pans connected to and supported by said projections, said projections being symmetrically positioned with respect to every other of said slots, the portions of said carrier between said projections being notched to a location spaced from said slots to provide said projections, said notches being substantially aligned with the remaining of said slots, said support portion providing an uninterrupted longitudinal part which cooperates with said mounting portion after said bending along said hinge line to maintain said carriers straight.
Claim 3
Dependent Claim
24 words
A linear system as set forth in claim 1, wherein said mounting portion is mounted on a building structure without bending said hinge means.
Claim 4
Dependent Claim
35 words
A linear system as set forth in claim 1, wherein said hinge means are bent, said mounting portion being mounted on a building structure, and said support portion extending substantially perpendicular to said mounting portion.
Claim 5
Dependent Claim
46 words
A carrier as set forth in claim 1, wherein said carrier is coiled in long lengths for convenient storage and handling and is adapted to be cut into separate pieces for installation, said mounting portion providing openings therein through which mounting fasteners are adapted to extend.
Claim 6
Dependent Claim
38 words
A carrier as set forth in claim 1, wherein said mounting portion is secured to an elongated bar to form a carrier bar assembly adapted to be suspended from a building structure to provide a suspended linear ceiling.
