Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
In a vehicle cab having a plurality of walls defining generally planar surfaces with edges therearound joined to form corners and supported by a plurality of horizontal and vertical beam members, generally planar panels contactingly positioned against said walls and similarly having edges therearound in juxtaposed relationship with the wall edges, the improvement comprising a plurality of retainer clip means for releasably securing said panels in their contacting positions, wherein said clip means comprise generally U-shaped edge retainer clips including generally parallel inner and outer legs joined by a bight portion so as to partially encompass the panel edge, an opening in said bight portion, and further including an edge clamping means comprising an edge clamp having elongated leg inserted through said opening and having a lip portion thereof contacting said edge retainer clip, whereby said panels may be easily removed and installed by removing said retainer clip means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
60 words
The invention of claim 1 wherein said walls have generally planar windows therein supported by molding therearound, an opening in said panel defining edges around said window and wherein said retainer clip means further comprises a plurality of retaining clips engageable with said molding and said panel opening edges so as to provide retention of said panels against said walls.
Claim 4
Dependent Claim
32 words
The invention of claim 2 wherein each of said retaining clips comprise generally S-shaped members having a clamping leg and a retaining leg in generally parallel relation and joined by a web.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
74 words
The invention of claim 1 further including a ceiling in said cab and having a horizontal beam member thereon, a pair of panels juxtaposed on either side of said horizontal beam member and wherein said clamping means further comprise a plurality of generally planar ceiling clips secured to said horizontal beam by fasteners, said ceiling clips extending on either side of said horizontal beam so as to contact and retain the pair of panels.
Claim 7
Dependent Claim
21 words
The invention of claim 1 wherein said lip on said elongated leg is a generally arcuate extension of said elongated leg.
Claim 8
Dependent Claim
