Wall lining with attachment means

Claim 2

A wall lining sheet comprising a rigid sheet having a plurality of spaced-apart bendable attachment tabs disposed in the plane of said sheet and each defined by a configured slot extending through said sheet, said sheet being free of support adjacent said tabs and each said tabs having a bendable free end portion and transverse opposed side edges free of said sheet whereby said bendable free end portion may be displaced outwardly from the plane of said sheet without deforming said sheet for securement of said sheet to a backing structure having an irregular outer plane, said securement being effected by a weld formed between said tabs and said outer plane through an opening formed by said configured slot after deformation of said tabs to an adjacent portion of said irregular plane.

Claim 3

A sheet as claimed in claim 1 wherein said sheet is a corrugated metal sheet having alternating ridges and channels extending parallel to one another across said sheet.

Claim 4

A sheet as claimed in claim 2 wherein said attachment tabs are located at predetermined intervals along at least some of said channels, said configured slot having a longitudinal central portion extending on the long axis of an associated channel to define said free end portion and transverse side portions formed with said central portion to define said opposed side edges and each extending on a common side of said longitudinal central portion to define said attachment tab therebetween.

Claim 5

A sheet as claimed in claim 3 wherein said transverse side portions each extend on opposed sides of said central portion with said central portion located substantially mid-way of each transverse end portions, said configured slot defining opposed attachment tabs.

Claim 6

A sheet as claimed in claim 4 wherein said configured slot central portion is progressively wider as said tabs are bent to a common side of said sheet to provide a progressively larger opening in said sheet for access to said tabs for welding said tabs to said backing structure.

Claim 7

A sheet as claimed in claim 4 in combination with a corrugated wall panel, said channels of said sheet extending transverse to corrugations of said corrugated wall panel with said attachment tabs aligned with respective ridges of said corrugations of said corrugated wall panel.

Claim 8

A sheet as claimed in claim 6 wherein said corrugated wall panel has an irregular planar inner surface with some of said ridges lying in different planes, at least some of said tabs being bent outwardly to contact a respective ridge of said corrugated wall panel and secured thereto by welds.

Claim 9

A sheet as claimed in claim 2 wherein said sheet is provided with vertical end edges formed along said ridges and offset inwardly of a front face of said sheet to accommodate a closure strip to be secured thereto without protruding above said front face.

Claim 10

In a railway car comprising corrugated end walls each having an outer face with elevated ridges, the improvement comprising a wall lining sheet secured over an inner face of each said end walls, said wall lining sheet comprising at least one metal sheet having a plurality of spaced-apart bendable attachment tabs disposed in the plane of said sheet and each defined by a configured slot extending through said sheet, each said tabs having a bendable free end portion and transverse opposed side edges free of said sheet whereby each said tabs is displaceable from its normal plane without deforming the sheet, at least some of said tabs being welded to said elevated ridges of said outer face of said end walls with at least some of said tabs bent outwardly of said sheet towards said inner face to compensate for irregular spacing between said outer face of said wall lining and said elevated ridges of said inner face of said corrugated end walls, said weld being formed between said tabs and said elevated ridges through an opening formed by said configured slot after deformation of said tabs to an adjacent portion of said elevated ridges.

Claim 11

In a railway car comprising corrugated end walls each having an outer face with elevated ridges, the improvement comprising a wall lining sheet secured over an inner face of each said end walls, said wall lining sheet comprising at least one metal sheet having a plurality of spaced-apart bendable attachment tabs disposed in the plane of said sheet and each defined by a configured slot extending through said sheet, each said tabs having a bendable free end portion and transverse opposed side edges free of said sheet whereby each said tabs is displaceable from its normal plane without deforming the sheet, at least some of said tabs being welded to said elevated ridges of said outer face of said end walls with at least some of said tabs bent outwardly of said sheet towards said inner face to compensate for irregular spacing between said outer face of said wall lining and said elevated ridges of said inner face of said corrugated end walls, said weld being formed between said tabs and said elevated ridges through an opening formed by said configured slot after deformation of said tabs to an adjacent portion of said elevated ridges.
