Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A method of attaching a roll over protecting structure to a vehicle having a frame including a plurality of sockets, the structure including a plurality of posts having extensions on their lower ends complementary to the sockets, comprising the steps of: supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit tightly between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the interior walls of the sockets; repositioning said structure on the frame with said extension resting in the corresponding socket; and securing each extension to the frame.
Claim 2
Independent Claim
114 words
A method of attaching a roll over protecting structure to a vehicle having a frame including a plurality of sockets, the structure including a plurality of posts having extensions on their lower ends complementary to the sockets, comprising the steps of: supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit tightly between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the interior walls of the sockets; repositioning said structure on the frame with said extension resting in the corresponding socket; and securing each extension to the frame.
Claim 3
Independent Claim
142 words
A method of attaching a roll over protection structure to a vehicle having a frame including a plurality of sockets, the structure including a plurality of posts having extensions on their lower ends complementary to the sockets, comprising the steps of: machining two opposite faces of each extension so that the distance between said faces is held to a close tolerance; securing each extension to one of the posts; supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit tightly between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the interior walls of the socket; repositioning said structure on the frame with each extension resting in the corresponding socket; and securing each extension to the frame.
Claim 4
Independent Claim
142 words
A method of attaching a roll over protection structure to a vehicle having a frame including a plurality of sockets, the structure including a plurality of posts having extensions on their lower ends complementary to the sockets, comprising the steps of: machining two opposite faces of each extension so that the distance between said faces is held to a close tolerance; securing each extension to one of the posts; supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit tightly between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the interior walls of the socket; repositioning said structure on the frame with each extension resting in the corresponding socket; and securing each extension to the frame.
Claim 5
Independent Claim
161 words
A method of attaching a roll over protection structure to a vehicle having a frame including a plurality of sOckets, each socket having one inclined wall, the structure including a plurality of posts, comprising the steps of; providing a plurality of extensions equal to the number of sockets; forming an inclined face on each extension complementary to the inclined wall of each socket; machining two opposite parallel faces of each extension so that the distance therebetween is held to a close tolerance; securing each extension to one of the posts; supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the sockets; repositioning said structure on the frame with each extension resting on the pads in the corresponding socket; and pinning each extension to the frame.
Claim 6
Independent Claim
161 words
A method of attaching a roll over protection structure to a vehicle having a frame including a plurality of sOckets, each socket having one inclined wall, the structure including a plurality of posts, comprising the steps of; providing a plurality of extensions equal to the number of sockets; forming an inclined face on each extension complementary to the inclined wall of each socket; machining two opposite parallel faces of each extension so that the distance therebetween is held to a close tolerance; securing each extension to one of the posts; supporting the structure above the frame with each extension within its corresponding socket; selecting from a plurality of elastomeric pads of various thickness one which will fit between each face of each extension and its corresponding socket; removing said structure; securing said selected pads to the sockets; repositioning said structure on the frame with each extension resting on the pads in the corresponding socket; and pinning each extension to the frame.
Claim 7
Dependent Claim
47 words
A method according to claim 3, and further comprising the steps of: providing an opening through said parallel faces on each extension; providing corresponding openings through the side walls of each socket; securing elastomeric washers around said corresponding openings; and inserting a pin through both said openings.
Claim 8
Dependent Claim
94 words
A means for attaching a roll-over protection structure to the frame of a vehicle, said means comprising: an extension secured to said structure; said extension having an inclined face and adjacent faces spaced apart a given distance within a close range of tolerance; a socket formed in said frame and having an inclined wall complementary to said inclined face; said socket being capable of accepting said extension; means for securing said extension on said socket; and resilient pads positioned between said socket and said extension to isolate said extension from vibrations in said frame.
Claim 9
Dependent Claim
94 words
A means for attaching a roll-over protection structure to the frame of a vehicle, said means comprising: an extension secured to said structure; said extension having an inclined face and adjacent faces spaced apart a given distance within a close range of tolerance; a socket formed in said frame and having an inclined wall complementary to said inclined face; said socket being capable of accepting said extension; means for securing said extension on said socket; and resilient pads positioned between said socket and said extension to isolate said extension from vibrations in said frame.
Claim 10
Dependent Claim
36 words
The invention according to claim 5, wherein said securing means comprises: a bore in said extension between said spaced faces; resilient washers secured in said socket; and pin means extending through said washers and said bore.
Claim 11
Dependent Claim
61 words
