Abstract
Abstract Apparatus for loading a boat on a vehicular or fixed support structure, such as a camper or a dock. An elongated carrier frame is provided having forward and rear ends. An upstanding supporting frame is provided having upper and lower ends, the lower end being rigidly mounted on the support structure. The rear end of the carrier frame is pivotally connected to the supporting frame adjacent the upper end thereof with the carrier frame extending forwardly therefrom and being pivotally movable between a horizontal, boat-carrying position and a forwardly and upwardly inclined, boat-loading position. A pair of elongated, boat-loading rails is provided having forward and rear ends. The rails have a loading position with their forward ends removably and pivotally connected to the supporting frame adjacent its upper end and being inclined rearwardly and downwardly therefrom, with their rear ends being supported by the ground. A winching system is provided for hauling the boat up the rails in their loading position and onto the carrier frame in its loading position. The rails have a stowed position in which they are carried by and secured to the carrier frame.

Claim 3
Dependent Claim
139 words
The apparatus of claim 1 wherein said rear end of said carrier frame is pivotally connected to said supporting frame whereby said carrier frame may be pivotally raised from a generally horiZontal carrying position to a forwardly and upwardly inclined loading position, said supporting means including a transversely extending member spaced rearwardly from said forward end of said carrier frame in said carrying position thereof, said carrier frame being supported by said transverse member in said carrying position, a longitudinally extending track on said carrier frame adjacent said forward end thereof, means for engaging said track for longitudinal movement thereon, and a hydraulic cylinder having one end pivotally connected to said transverse member and its piston rod pivotally connected to said engaging means whereby extension of said piston rod pivotally raises the carrier frame to said loading position thereof.
Claim 4
Dependent Claim
75 words
The apparatus of claim 2 wherein said supporting means further includes a pair of elongated stabilizer rods respectively having forward and rear ends and being respectively disposed on opposite sides of said cylinder, the forward ends of said rods being pivotally connected to said engaging means, and means for pivotally connecting the rear ends of said rods to said transverse member at points spaced from opposite sides of said carrying frame in said carrying position.
