Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
Vehicle with dismountable ramp comprising a vehicle body having an upper surface portion and two ends adapted for mounting ramps thereon, at least one deploying and drive-on ramp pivoted to one end of said vehicle body and having a tapered surface, and an elongated dismountable ramp having a tapered section conforming to and overlapping said tapered surface of said deploying ramp, means for coupling said tapered section to said tapered surface so that said ramps constitute a unit pivotable about said vehicle body to be either supported on said vehicle body or to extend therefrom, said means comprising a releasable pivot connection between said deploying and drive-on ramp and said dismountable ramp and a separable connection at a point spaced from said pivot operable to release and drop the overlapping tapered section of said elongated dismountable ramp from said deploying and drive-on ramp to rest on the ground.
Claim 2
Dependent Claim
148 words
Vehicle with dismountable ramp comprising a vehicle body having an upper surface portion and two ends adapted for mounting ramps thereon, at least one deploying and drive-on ramp pivoted to one end of said vehicle body and having a tapered surface, and an elongated dismountable ramp having a tapered section conforming to and overlapping said tapered surface of said deploying ramp, means for coupling said tapered section to said tapered surface so that said ramps constitute a unit pivotable about said vehicle body to be either supported on said vehicle body or to extend therefrom, said means comprising a releasable pivot connection between said deploying and drive-on ramp and said dismountable ramp and a separable connection at a point spaced from said pivot operable to release and drop the overlapping tapered section of said elongated dismountable ramp from said deploying and drive-on ramp to rest on the ground.
Claim 3
Dependent Claim
27 words
Vehicle in accordance with claim 1, where said dismountable ramp and the other end of said drive-on ramp are connected at three joints including said releasable pivot.
Claim 4
Dependent Claim
47 words
Vehicle in accordance with claim 2, including a hydraulic cylinder operatively connected intermediate said vehicle body and said at least one drive-on ramp, and a hydraulic rocking cylinder connected intermediate said vehicle and said pivot joint for overcoming the dead point during unfolding of said dismountable ramp.
Claim 5
Dependent Claim
46 words
Vehicle in accordance with claim 3, where said dismountable ramp comprises a pair of ramp parts each having substantially the same length as said vehicle and pivotally connected to one another transversely of said vehicle at the ends opposite the end connected to said vehicle body.
Claim 6
Dependent Claim
116 words
Vehicle in accordance with claim 4, said releasable pivot connection comprising a tranversely extending element defining a pivot means disposed intermediate the component defining said deploying ramp and the component defining said dismountable ramp, and secured to one said component, a generally tongue shaped abutment on the other said component, a lever mounted on a pivot pin on the other said component having a gripping arm portion on one side of said pivot pin engageable with said transversely extending element and operative to establish engagement between said transversely extending element and said abutment and having a pulling arm portion on the other side of said pivot pin, and a pulling element connected to said pulling arm.
