Abstract
Abstract A roll protective structure is provided in which a roof panel and floor panel are detachably mounted thereto. The mounting means are such that structural rigidity is maintained while insuring that there is no metal-to-metal contact between the respective panels and cab structure. The respective panels also provide for sound insulation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
In a roll protective structure for use in off-highway vehicles, the combination comprising: a cab frame defining an operator enclosure area; a roof panel to protect the operator, said roof panel including a top plate; said top plate being formed to have a projecting lip about the periphery thereof wherein said projecting lip overlaps the cab frame when said roof panel is placed in close proximity to said frame; elongated mounting means removably attached to said cab frame and overlapping the entire length of said projecting lip, thereby securing said roof panel to said cab frame to cover the entire ceiling area; resilient means mounted about said projecting lip to resiliently support in isolating fashion and to prevent metal-to-metal contact between said panel lip and said cab frame and said mounting means; a floor panel; second mounting means removably securing said floor panel to said cab frame; and second resilient means operatively associated with said floor panel to resiliently support in isolating fashion said floor panel from said cab frame and said mounting means.
Claim 2
Dependent Claim
174 words
In a roll protective structure for use in off-highway vehicles, the combination comprising: a cab frame defining an operator enclosure area; a roof panel to protect the operator, said roof panel including a top plate; said top plate being formed to have a projecting lip about the periphery thereof wherein said projecting lip overlaps the cab frame when said roof panel is placed in close proximity to said frame; elongated mounting means removably attached to said cab frame and overlapping the entire length of said projecting lip, thereby securing said roof panel to said cab frame to cover the entire ceiling area; resilient means mounted about said projecting lip to resiliently support in isolating fashion and to prevent metal-to-metal contact between said panel lip and said cab frame and said mounting means; a floor panel; second mounting means removably securing said floor panel to said cab frame; and second resilient means operatively associated with said floor panel to resiliently support in isolating fashion said floor panel from said cab frame and said mounting means.
Claim 3
Dependent Claim
37 words
The combination as set forth in claim 1 in which said top plate terminates in a rail portion extending downwardly from said lip wherein said rail portion provides structural rigidity to prevent bending of said roof panel.
Claim 4
Dependent Claim
37 words
The combination as set forth in claim 2 in which said mounting means is an elongated clamping strip, said strip having one edge connectable with said cab frame and the other edge acting against said resilient means.
Claim 5
Dependent Claim
37 words
The combination as set forth in claim 3 in which said resilient means is an elongated rubber element extending the entire length of said panel peripheral lip and extending over the top and bottom of said lip.
Claim 6
Dependent Claim
34 words
The combination as set forth in claim 1 further comprising a support member fixedly secured to said cab frame along the bottom thereof, said support member being used to support said floor panel thereupon.
Claim 7
Dependent Claim
48 words
The combination as set forth in claim 5 in which said floor panel has a peripheral edge projecting therefrom and in which said second resilient means is an elongated cushioning member mounted about said support member wherein said floor panel peripheral edge is supported on said cushioning member.
Claim 8
Dependent Claim
86 words
The combination as set forth in claim 6 in which said second mounting means comprises an elongated clamping strip, one elongated edge of said strip being detachably secured to said floor panel and said strip other elongated edge engaging said cushioning member on the side of said support member opposite the panel edge supporting side wherein said floor panel is supported by said cushioning member about its entire peripheral edge and said clamping strip prevents relative upward movement between said floor panel and said cab frame.
Claim 9
Dependent Claim
35 words
The combination as set forth in claim 7 in which said floor panel has a double wall, said double wall defining passageways therebetween wherein vehicle hoses and cables and the like may be passed therethrough.
Claim 10
Dependent Claim
126 words
The combination as set forth in claim 3 comprising a support member fixedly secured to said cab frame along the bottom thereof; said floor panel having a peripheral edge projecting therefrom; said second resilient means being an elongated cushioning member placed about said support member wherein said floor panel peripheral edge is supported on said cushioning member; said second mounting means being an elongated clamping strip, one edge of said strip being detachably secured to said floor panel and said strip other edge engaging said cushioning member on the opposite side of said channel member wherein said floor panel is supported by said cushioning member about its entire peripheral edge and said clamping strip prevents relative upward movement between said floor panel and said cab frame.
