Total Claims: 13
Claim 1
Independent Claim
350 words
An apparatus for loading a boat trailer with an axle, wheels and tongue, to a position above the bed of a pickup truck and maintaining it in that position, said pickup truck having a cab, said apparatus comprising a loading frame rigidly mountable in the bed of the pickup truck for disposition at the front of the truck bed, the loading frame including a trailer tongue support attached thereto and disposed above the truck bed at the front thereof, and having cable extending and retracting means coupled thereto a cable having a first and a second end, the first end being integrally connected to the cable extending and retracting means and the second end having coupling means for temporarily attaching the cable to the boat trailer to pull the boat trailer forward toward the front of the truck bed when the cable is retracted; guiding means for directing the cable along a predetermined alignment, said guiding means comprising a first and a second end and means for channeling the tongue of the trailer in a substantially straight path as the trailer is loaded, the first end of said guiding means being pivotally connected to the loading frame and not substantially extending over the cab of the pickup truck; lifting means having first and second ends, the first end of said lifting means being pivotally connected to the loading frame and the second end of said lifting means having receiving means for engaging the axle of the boat trailer as it is pulled forward, said lifting means in combination with the guiding means and loading frame thereby providing for hoisting the trailer clear of and above the bed of the pickup truck with the trailer axle resting on the lifting means and the trailer tongue resting on the tongue support; and at least one ramp having a first and a second end, the first end of the ramp being disposable on the bed of the pickup truck and the second end being disposable on the ground so that as the trailer is pulled forward, the trailer wheels ride over the ramp.
