Abstract
Abstract A cushioning liner is disclosed which combines a plurality of elongated elastomeric sheet members and a plurality of elongated elastomeric rib members mounted between adjacent edges of sheet members. The ribs are provided with T-shaped longitudinal slots along which metal plates extend to distribute clamping loads. Bolt fasteners are mounted in the plate at spaced intervals therealong to bolt the ribs to the supporting surface and in turn clamp the sheets in position. The ribs and sheets are provided with mating interlocking surface arranged so that they provide mutual lateral support.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
174 words
A liner structure comprising a surface subject to impact or the like, an elongated sheet member formed of elastomeric material having a back side fitting along said surface and a front side, rib members formed of elastomeric material fitting along each longitudinal edge of said sheet member and providing a portion overlapping the surface of said front side adjacent to the associated edge, a plurality of fastening means spaced from the surface of said rib and spaced therealong, said fastening means securing said rib to said surface and applying forces pressing said portion against said front side, said fastening means including force distributing means operating to distribute said forces over a substantial area within said rib, said rib covering said fastening means with a thickness sufficient to provide substantial cushioning of said fastening means and preventing damage thereto, said sheet member and said rib members providing mating faces forming an interlocking groove and projection connection extending substantially parallel to the adjacent edge of said sheet member and providing mutual lateral support between said members.
Claim 2
Dependent Claim
174 words
A liner structure comprising a surface subject to impact or the like, an elongated sheet member formed of elastomeric material having a back side fitting along said surface and a front side, rib members formed of elastomeric material fitting along each longitudinal edge of said sheet member and providing a portion overlapping the surface of said front side adjacent to the associated edge, a plurality of fastening means spaced from the surface of said rib and spaced therealong, said fastening means securing said rib to said surface and applying forces pressing said portion against said front side, said fastening means including force distributing means operating to distribute said forces over a substantial area within said rib, said rib covering said fastening means with a thickness sufficient to provide substantial cushioning of said fastening means and preventing damage thereto, said sheet member and said rib members providing mating faces forming an interlocking groove and projection connection extending substantially parallel to the adjacent edge of said sheet member and providing mutual lateral support between said members.
Claim 3
Dependent Claim
46 words
A liner structure as set forth in claim 1 wherein said mating faces formed on said sheet member include a first face extending substantially normal to said front side spaced from the adjacent longitudinal edge and a second face inclined therefrom back toward said front face.
Claim 4
Dependent Claim
20 words

Claim 12
Dependent Claim
44 words
A liner structure as set forth in claim 1 wherein a plurality of adjacent sheet members are secured to said surface, and at least some of said rib members are associated in a similar manner with an adjacent sheet member on each side thereof.
Claim 13
Dependent Claim
46 words
A combination as set forth in claim 11 wherein said surface includes two planar portions joined along an intersection forming an obtuse angle, at least some of said rib and sheet members extending across said intersection, and separate plates provided on each side of said intersection.
Claim 14
Dependent Claim
20 words
A combination as set forth in claim 12 wherein said surface is part of a load body of a vehicle.
Claim 15
Dependent Claim
38 words
A combination as set forth in claim 13 wherein a rigid end support formed with a profile similar to the profile of the liner is mounted on said surface adjacent to at least one end of said liner.
