ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a combination utility trailer. More specifically, the invention is a convertible elevated observation stand, luggage/personnel/kayak carrier, tent, pontoon boat, and farm plow which can be mounted on or trailered by open bed vehicles such as ATV's, trucks or farm tractors.
2. Description of the Related Art
The related art of interest describes various hunting stands, tents, carts, and the like for towing by a vehicle, but none discloses the present versatile invention. There is a need for a convertible trailer for serving multiple uses. For connection to an open bed vehicle such as an ATV, a tent with inside lighting, a pontoon boat, a fishing platform, a kayak, a luggage and personnel carrier, and a hunting stand combination is provided. For a trailer converted to a farm plow, an ATV or a tractor can be used.
The relevant art will be discussed in the order of perceived relevance to the present invention.

None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant invention as claimed. Thus, a viewing perch among other utility apparatuses for open bed vehicles solving the aforementioned problems is desired.
SUMMARY OF THE INVENTION
The present invention is a convertible, elevated observation stand with a seat, luggage carrier, tent, kayak carrier and a pontoon boat which can be mounted on or trailered by open bed vehicles such as ATV's, trucks or the like vehicles. The ladder-type frame on wheels can be used as a utility trailer with a folding seat pivoted outside for hauling equipment, game or an injured person, and readily converted to an elevated position with a lifting system and used as a viewing or hunting stand. The apparatus can be raised to the elevated position by hand or by a winch, can serve as a tent shelter with bunk-type cots placed inside, and can be wired for lighting which is energized by the vehicle's battery. For conversion to a trailerable boat, the frame can be covered with waterproof liner, inflatable pontoons can be attached to each side, an additional seat added, and an electric motor mounted on the rear. A fishing platform still attached to the vehicle would not require the pontoons and engine. For carrying a kayak, the apparatus can include a pair of elevated racks. For forming a farm plow, the frame can support cultivator blades for towing by an ATV or a farm tractor. Skis can be attached to the frame for towing by a snowmobile.
Accordingly, it is a principal object of the invention to provide a combination apparatus trailerable by an open bed vehicle, a farm tractor or a snowmobile.
It is another object of the invention to provide a combination apparatus trailerable by an open bed vehicle and convertible to an elevated viewing or hunting stand, a tent, a carrier of luggage/injured personnel/game, and a pontoon boat.
It is a further object of the invention to provide a fishing platform still attached to the vehicle and maintained in shallow water.
Still another object of the invention is to provide a farm plow by adding an array of cultivator blades below the frame and towing by an ATV or a farm tractor.
It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which is i
