Abstract
Abstract The invention relates to lining systems for building surfaces such as walls or ceilings. The structure uses at least two spaced parallel rails, adjustable connectors sliding on the rails and panel attachment members secured to the rails by the connectors and serving to support facing panels, for example gypsum wall boards. The connectors are adjustable in three mutually perpendicular directions being slidable along the rails and along the attachment members and adjustable to vary the spacing between the rail and the attachment member. Panels may be secured to the attachment members by any suitable means such as screws, clips, adhesives or edge engagement. Attachment members may be elongated, in the form of studs, or short locally operative clips. The lining system enables irregularities of the underlying structure to be accommodated and a planar lining produced.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A lining structure for attaching panels to a supporting building surface or frame, said structure comprising at least two rails provided for attachment to the surface or frame, said rails being substantially parallel to each other, panel attachment members adapted to engage and support lining panels, and connectors operatively associated with said rails, and said panel attachment members for connecting said panel attachment members to said rails so that they are adjustable in three mutually perpendicular directions, said connectors being provided with a plurality of parallel flanges containing a plurality of grooves disposed therebetween, said associated rail being slidably disposed in any one of said plurality of grooves, and the connectors also being provided with a recess which is adapted to engage and slidably retain the associated panel attachmennt member, said panel attachment member extending in a direction at right angles to the rails.
Claim 2
Dependent Claim
144 words
A lining structure for attaching panels to a supporting building surface or frame, said structure comprising at least two rails provided for attachment to the surface or frame, said rails being substantially parallel to each other, panel attachment members adapted to engage and support lining panels, and connectors operatively associated with said rails, and said panel attachment members for connecting said panel attachment members to said rails so that they are adjustable in three mutually perpendicular directions, said connectors being provided with a plurality of parallel flanges containing a plurality of grooves disposed therebetween, said associated rail being slidably disposed in any one of said plurality of grooves, and the connectors also being provided with a recess which is adapted to engage and slidably retain the associated panel attachmennt member, said panel attachment member extending in a direction at right angles to the rails.
Claim 3
Dependent Claim
55 words
A lining structure according to claim 1 wherein said connector comprises at least two portions, one of which is formed with said grooves and mounted on the rail and the other of which is attached to the first-mentioned portions by means which enable the relative positions of the two portions to be varied or adjusted.
Claim 4
Dependent Claim
29 words
A lining structure according to claim 1 wherein said panel attachment member is an elongate member provided with flanges for engaging the edges of adjacent panels or wall boards.
Claim 5
Dependent Claim
28 words
A lining structure according to claim 1 wherein said attachment members are individual clips adapted to engage adjacent wallboards or panels locally in the vicinity of each connector.
Claim 6
Dependent Claim
34 words
A lining structure according to claim 1 wherein said panel attachment member is an elongate member and said panels are fixed to said members by means of screws, clips, adhesives and like fixing means.
Claim 7
Dependent Claim
32 words
A lining structure according to claim 1 wherein said connector is a single integral member having said flanges and grooves at one end thereof and said recess at the opposite end thereof.
Claim 8
Dependent Claim
66 words
A lining structure according to claim 6 wherein said recess at said opposite end of said connector is shaped to fit the terminal one of said flanges at said one end of said connector, whereby at least two such connectors can be joined together to provide a greater spacing between said rail and said panel than is afforded by the use of one of said connectors.
