Abstract
Abstract A boat loading structure includes a trailer having a pair of longitudinally extending side rails. A plurality of pairs of bar assemblies are mounted on the side rails, each bar assembly of each pair being mounted on respective side rails. The pairs of bar assemblies are mounted in a plane perpendicular to the longitudinally extending side rails. Each of the bar assemblies includes a base secured to one of the side rails. A vertical rod extends upwardly from the base. A spring interconnects the base and the vertical rod. A roller member is rotatably mounted on the other end of the vertical rod.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A boat loading structure comprising: a boat trailer including a pair of longitudinally extending side rails; at least one pair of bar assemblies, each of said bar assemblies of each pair being mounted on respective side rails, said pair being mounted in a plane generally perpendicular to said side rails; each of said bar assemblies comprising: a base secured to said side rails; a vertical rod extending upwardly from said rail; a spring interconnecting said base and one end of said vertically extending rod; a roller member rotatably mounted on the other end of said spring rod; and means for varying the spacing between the springs of each bar assembly pair for providing a continuous variable adjustment of the amount of pressure exerted by said roller members.
Claim 2
Dependent Claim
127 words
A boat loading structure comprising: a boat trailer including a pair of longitudinally extending side rails; at least one pair of bar assemblies, each of said bar assemblies of each pair being mounted on respective side rails, said pair being mounted in a plane generally perpendicular to said side rails; each of said bar assemblies comprising: a base secured to said side rails; a vertical rod extending upwardly from said rail; a spring interconnecting said base and one end of said vertically extending rod; a roller member rotatably mounted on the other end of said spring rod; and means for varying the spacing between the springs of each bar assembly pair for providing a continuous variable adjustment of the amount of pressure exerted by said roller members.
Claim 3
Dependent Claim
27 words
A boat loading structure in accordance with claim 1 wherein said roller members are cup-shaped and contain a self-lubricating bearing surface formed against the vertically extending rod.
Claim 4
Dependent Claim
17 words
A boat loading structure in accordance with claim 1 wherein a slidable protective sleeve surrounds said rod.
Claim 5
Dependent Claim
114 words
A boat loading structure comprising: a boat trailer including a pair of longitudinally extending side rails; at least one pair of bar assemblies, each of said bar assemblies of each pair being mounted on respective side rails, said pair being mounted in a plane generally perpendicular to said side rails; each of said bar assemblies comprising: a base secured to said side rails; a vertical rod extending upwardly from said rail; a spring defined by a coil looped in a plane perpendicular to the axis of said side rails interconnecting said base and one end of said vertically extending rod; and a roller member rotatably mounted on the other end of said spring rod.
Claim 6
Dependent Claim
114 words
A boat loading structure comprising: a boat trailer including a pair of longitudinally extending side rails; at least one pair of bar assemblies, each of said bar assemblies of each pair being mounted on respective side rails, said pair being mounted in a plane generally perpendicular to said side rails; each of said bar assemblies comprising: a base secured to said side rails; a vertical rod extending upwardly from said rail; a spring defined by a coil looped in a plane perpendicular to the axis of said side rails interconnecting said base and one end of said vertically extending rod; and a roller member rotatably mounted on the other end of said spring rod.
