Trailer with removable boat cover
A road trailer whose top is a removable boat or boat-shaped cover that secures to the trailer rim; the trailer has side and front panels, a floor on the frame, and longitudinal bunkers that retract into or below the floor. It is intended for vehicle owners or small boat owners who want to carry a boat as the trailer roof and to load the boat directly from the water. The design also discloses an alternative with an upper frame pivotally attached to the front panel that carries the removable boat.
(57) What the patent covered
This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.
The main independent claim required a trailer frame with wheels, opposing side panels and a front panel forming a rim, a floor spanning between the side-panel lower edges, a boat removably attached to the top edges of the opposing side panels, and bunkers running the trailer length that are retractable from above the floor to positions in or below the floor. An alternative independent claim substituted an upper frame pivotally attached to the front panel upper edge, aligned with the side-panel upper edges, with the boat removably attached to that upper frame.
Distinguishing feature: Integration of a removable boat as the trailer top combined with longitudinal retractable bunkers or a pivoting upper frame that carries the boat.
Novelty 3/5. Putting a boat on a trailer roof and using simple retractable bunks were known; the claimed combination of a removable boat cover plus bunkers that retract into or below the floor or a pivoting upper frame is a practical improvement rather than a wholly new category.
Manufacturing
Welded steel or aluminum frame fabrication; stamped or roll-formed panel parts; molding and finishing of a boat hull; bunkers formed from wood/composite and fitted into routed floor channels; assembly with fasteners and hinges.
Materials: Steel or aluminum trailer frame, sheet metal side and front panels (steel or aluminum), marine-grade fiberglass or aluminum boat hull (likely), timber or composite bunkers with rollers or slides (likely).
Manufacturability 4/5. Several stamped/molded panels, a fabricated frame and a removable boat/upper frame require moderate tooling, sourced boat hulls or in-house boat molding, and hand assembly for hinges and fasteners.
