Abstract
Abstract A fabricated corner structure having a single piece outer member and two piece inner member construction for receiving tubular members generally perpendicular to each other encompassed by the inner and outer members with a vertical support member perpendicular to the tubular members welded to the outer member. The three tubular members form the corner of a ROPS structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
226 words
A corner structure for a vehicle roll over protective structure having three members coming together to form a corner thereof for slidably receiving at least one member therein comprising: an outer member for receiving the corner members, at least one inner member, an unbroken face on said outer member adjoining at least one corner member, a first extension on said outer member extending generally perpendicularly outwardly from said face and a second extension generally perpendicular to said face and first extension, said second extension extending outwardly from said face, said first and second extension adjoining and being nondetachably affixed to a second corner member to form a common unbroken surface for the entire surface of said outer member, a first leg on said inner member spaced from and parallel to said outer member face, a second leg on said inner member generally perpendicular to said first leg and parallel to and spaced from said outer member first extension, said first and second inner legs nondetachably affixed to and abutting said outer member face and first extension, respectively, and together therewith encompassing said one corner member, said inner member having a length extending over most of the length common to both said one corner member and outer member first extension and means fastening said one corner member to said corner structure by passing through both said structures.
Claim 2
Dependent Claim
226 words
A corner structure for a vehicle roll over protective structure having three members coming together to form a corner thereof for slidably receiving at least one member therein comprising: an outer member for receiving the corner members, at least one inner member, an unbroken face on said outer member adjoining at least one corner member, a first extension on said outer member extending generally perpendicularly outwardly from said face and a second extension generally perpendicular to said face and first extension, said second extension extending outwardly from said face, said first and second extension adjoining and being nondetachably affixed to a second corner member to form a common unbroken surface for the entire surface of said outer member, a first leg on said inner member spaced from and parallel to said outer member face, a second leg on said inner member generally perpendicular to said first leg and parallel to and spaced from said outer member first extension, said first and second inner legs nondetachably affixed to and abutting said outer member face and first extension, respectively, and together therewith encompassing said one corner member, said inner member having a length extending over most of the length common to both said one corner member and outer member first extension and means fastening said one corner member to said corner structure by passing through both said structures.
Claim 3
Dependent Claim
17 words
The corner structure defined in claim 1 wherein said outer member is formed from a single plate.
Claim 4
Dependent Claim
14 words
The corner structure defined in claim 1 wherein said inner member is L shaped.
Claim 5
Dependent Claim
28 words
The corner structure defined in claim 1 wherein said fastening means includes a pair of bolt assemblies spaced from each other over the length of said inner member.
Claim 6
Dependent Claim
35 words
The corner structure defined in claim 1 including a second inner member for encompassing a third corner member generally perpendicular to the first and second corner members and adjoining said face of said outer member.
Claim 7
Dependent Claim
53 words
The corner structure defined in claim 5 wherein said second inner member includes a first leg spaced from and parallel to said outer member face and a second leg on said inner member generally perpendicular to said second inner member first leg and parallel to and spaced from said outer member second extension.
Claim 8
Dependent Claim
46 words
The corner structure defined in claim 5 wherein said outer member extensions have extended upper and lower portions said length of said upper portions matched by the length of said first and second inner members, said lower portions being fixedly attached to the second corner member.
Claim 9
Dependent Claim
65 words
The corner structure defined in claim 5 wherein said fastening means includes bolt assemblies for each of said inner members, respectively, in planes perpendicular to each other, one plane passing through said outer member extension and inner member second leg and the other plane passing through said outer member face and other inner member first leg to provide alternating bolt patterns for said corner structure.
Claim 10
Dependent Claim
26 words
The corner structure defined in claim 7 wherein said outer member face extends outwardly at right angles along said inner members to match the length thereof.
Claim 11
Dependent Claim
45 words
The corner structure defined in claim 9 wherein said inner members are L shaped and said outer plate extensions form L shapes with said outer plate face, said inner and outer members forming a socket of square cross section for receiving square tubing corner members.
