Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 305 words
A travel trailer or mobile home, having a patio that is slidable between a stored-away and utility positions, comprising, in combination, a chassis mounted at its rear upon wheels, a hitch at the front of said chassis for support from the rear of a towing vehicle, a trailer body upon said chassis, and a retractable patio assembly mounted on an underside of said chassis, said patio assembly comprising a pair of parallel, spaced-apart channels affixed to said chassis underside, grooves of said channels facing each other, so as to form guide rails, a frame slidably supported in said guide rails, and being sidewardly slidable partly outward from under said chassis, a plywood panel mounted upon said frame, a carpet mounted upon said panel, a hand rail hinged along edges of said frame, and being pivoted downwardly against the top of said carpet, when said frame is in slided position under said chassis, a protective cover affixed between said channels extending across the top of said downwardly pivoted hand rail, and preventing roadway mud from being splashed upon said carpet, a pair of locking pins removably secured in said channels and said frame for preventing accidental sliding of said frame from under said chassis during travel of said travel trailer or mobile home, a plurality of angled hand rail brackets being removably received in sleeves affixed to said frame, for rigidly holding said hand rail in vertically upright pivoted position, when said frame is in said outwardly slided position, for the safety of persons upon said patio, a pair of downwardly adjustable caster units removably attachable to outward corners of said frame, for support upon the ground when in said outwardly slided position, and a downwardly adjustable stabilizer secured under the center of said frame, for resting upon said ground when in said outwardly slided position.
Claim 2
Dependent Claim 305 words
A travel trailer or mobile home, having a patio that is slidable between a stored-away and utility positions, comprising, in combination, a chassis mounted at its rear upon wheels, a hitch at the front of said chassis for support from the rear of a towing vehicle, a trailer body upon said chassis, and a retractable patio assembly mounted on an underside of said chassis, said patio assembly comprising a pair of parallel, spaced-apart channels affixed to said chassis underside, grooves of said channels facing each other, so as to form guide rails, a frame slidably supported in said guide rails, and being sidewardly slidable partly outward from under said chassis, a plywood panel mounted upon said frame, a carpet mounted upon said panel, a hand rail hinged along edges of said frame, and being pivoted downwardly against the top of said carpet, when said frame is in slided position under said chassis, a protective cover affixed between said channels extending across the top of said downwardly pivoted hand rail, and preventing roadway mud from being splashed upon said carpet, a pair of locking pins removably secured in said channels and said frame for preventing accidental sliding of said frame from under said chassis during travel of said travel trailer or mobile home, a plurality of angled hand rail brackets being removably received in sleeves affixed to said frame, for rigidly holding said hand rail in vertically upright pivoted position, when said frame is in said outwardly slided position, for the safety of persons upon said patio, a pair of downwardly adjustable caster units removably attachable to outward corners of said frame, for support upon the ground when in said outwardly slided position, and a downwardly adjustable stabilizer secured under the center of said frame, for resting upon said ground when in said outwardly slided position.
Claim 3
Dependent Claim 115 words
The combination according to claim 1, wherein said frame is rectangular in configuration and includes a pair of side tubular members fixedly secured at their ends, to the ends of a pair of longitudinal tubular members, and a center and longitudinal tubular member is fixedly secured at its ends, between said pair of side tubular members, said frame including a plurality of spaced-apart cross-members of tubular configuration, which are fixedly secured in a suitable manner, at each end, to and between said pair of longitudinal tubular members and said center and longitudinal member, and said stabilizer member is fixedly secured in a suitable manner, to, and in alignment with, a center one of said cross-members.
