BACKGROUND OF INVENTION 
     1. The Field of Invention 
     The present invention relates to a multi-purpose ATV trailer. Both for transporting ATV&#39;s on public roads and highways and the same trailer may be pulled by ATV&#39;s on trails, having storage compartments for gear or equipment. 
     2. Description of Related Art 
     Many times it is needful to transport an ATV on the public roads to a desired location, most often by means of a utility trailer or flat bed or pick-up truck, once to this location it is offloaded from the trailer or truck, and if tools/gear or equipment are needed, it is then loaded or packed on the back of the ATV or into a trailer made for trail use for ATV&#39;s, this ATV trailer must also be transported along with the ATV in the utility trailer. 
     ATV trailers along with utility trailers are well known in art. However, the trailers and storage units in prior art do not provide a versatile trailer that eliminates the need for two trailers and incorporates storage, making it adaptable to many types of activities one might engage in. 
     The Huff U.S. Pat. No. 3,731,831 discloses a trailer capable of loading or unloading from either end having a pivoting draw bar, also having storage area over the wheels that extends both above and below the deck height, however this trailer is not meant for trail use and structure has little in common with this present invention. 
     The Richard U.S. Pat. No. 7,188,857 discloses a transformable trailer having capability short box trailer into a flat bed trailer, has little or no structure found in this present invention. 
     The Niehoff U.S. Pat. No. 6,378,904 discloses an ATV trailer having a steel tubing frame and heavy duty axle, triangular wings for tree deflector, and has a single center cargo area, however it&#39;s structure is otherwise different from this present invention. 
     The Greer U.S. Pat. No. Des. 601,059 has an ATV trailer with an enclosed cargo bed, but has little structure in common with the present invention. 
     The Cheney U.S. Pat. No. 5,299,722 shows a double lid truck storage box mounted in the back of a pick-up box, this storage being similar only in that it protects against the elements, and designed for fitting the back of a pick-up box, it&#39;s application differs from this current invention. 
     The Mishoe U.S. Pat. No. Des. 376,564 discloses an ATV trailer having a tip-up ramp with an open frame design, rather than a versatile trailer with storage found in this present invention. 
     The Neage, Meidanis &amp; Koehler U.S. Pat. No. 6,129,401 disclose a vehicle storage bin that lies below the normal bed of the truck and conforms to the cosmetics of the exterior but has no structure in common with current invention. 
     Whatever the features, advantages or merits of the above cited references may be, none of them achieves the purposes of the trailer of this present invention. 
     SUMMARY OF INVENTION 
     The present invention is a multi-purpose ATV trailer that can both haul an ATV loaded on it and be pulled by an automobile or pick-up truck on public roadways, or be pulled by an ATV on trails or off road, this trailer having a preferred steel tube structure utilizing the axle tube and tong as supporting members for a gap bed and opposing wishbone frame, that can carry a storage box that protects gear or cargo against the elements, this box is nested in the gap bed, and it extends from below the deck level to above the deck level were the wheels of the ATV when loaded straddle the storage box (that extends above the deck level) taking advantage of the ground clearance that&#39;s built into the design of modern ATV&#39;s, also having a separate storage area that extends to the front or rear of the main storage box, this smaller (in volume, not height or width) storage area is covered yet is vented so a person can carry a gas or fuel cans without any build up of fumes or contaminating cargo in the large storage box, this trailer may also incorporate hinged decking to access storage areas directly bellow the decking, the center of gravity of this new trailer design makes it road and trail worthy, and allows a person to load their equipment one time, and eliminates the need for two trailers. 
     An object of the invention is to provide a dual purpose ATV trailer having the capability to transport an ATV on public roads and also be used off road towed by an ATV. 
     Another object of this invention is to provide an ATV trailer with a gap frame design to accommodate a storage box that extends from bellow the deck to above the deck, for transporting gear/equipment protecting them from the elements. 
     Still another object is maximizing space both above and below the deck or bed area by taking advantage of the ground clearance of an ATV, and space below the deck level, yet retaining reasonable ground clearance.

     DETAILED DESCRIPTION OF THE INVENTION 
     Refer now to  FIG. 2  which is an overall drawing of a preferred embodiment of the invention. The multipurpose ATV trailers size is just slightly wider than an ATV being a few inches on each side, and length about the same as an ATV that its designed for, there being many different sizes of ATV&#39;s, trailers would be designed with axle tube  20  or torsion suspension matched to accommodate the weight of the vehicle it&#39;s designed to carry and an additional payload, wherein the frame members are tubing made of steel or alloy, frame members are welded to each other, and axle tube  20  is bolted in position, gussets  39  may be added for ease of welding or for strengthening where needed to construct the frame, frame mount plates  22 , these mount plates are bolted or welded to the axle tube mounts  41 , axle tube  20  has mounting flanges  41  located that the bridge frame seen in FIG. C will attach to  22  frame mounting plates, preferably  20  consists of a torsion tube suspension, the overall length of  20  is equal to the width of the trailer including the wheels  36 , tongue channel  19  is also bolted or welded to the axle tube tongue mount  42 , bolting the axle tube in place could allow for better axle service and manufacturing purposes, tongue channel  19  is a welded into the construction of the frame, transferring the load from hitch to axle tube, by doing so it removes stress off the smaller frame members,  19  at the front of trailer adjoins  21  that consists of a steel piece that is welded to several frame members for strength, tongue channel  19  has member  11  front tongue being just slightly smaller in size to allow the two pieces  19  and  11  to slide one inside the other to give the driver more options on the overall tongue length, for trail riding, one may want a short tongue for better trailing abilities, and for hi-way a person may want a longer tongue length, implementing a typical ball hitch  12  attached to the end of member  11  for towing trailer behind an auto, pick-up truck or ATV. 
     The gap bed frame shown in FIG. A is given strength by the lateral bridge type assembly containing member  31  shown in FIG. C in conjunction with lateral members  29 , angular braces  33 , vertical members  34 , along with member  22  the axle mounting plate that is on the bottom of the assembly, this assembly stands vertical, and parallel to the tongue of the trailer, two of these bridge assemblies create the gap in the trailer by being connected on the bottom by member  35  as seen in FIG. A, bridge assemblies are the width gap bed positioning them directly bellow the deck on the inside edge, and travel the entire length of the trailer, from these lateral bridge assemblies are connected the wishbone deck support braces, member  28  and  32  as seen in FIG. A with member  35  located at every section that has a wishbone support, these supports adjoins member  37 , member  37  is the outward most member to which the deck  2  rests upon, following the deck, starting from the fenders  3  horizontal along the outside edge, around the corners  6  making the 90 degree corner continuing to member  29  where both member&#39;s top surfaces adjoins flush, a dashed line in FIG. A shows member  38  seen in  FIG. 1 , this member ties the two wishbone weldment together in multiple locations in a plane that is the same level as the upper wishbone members  32  and upper member  29  of the lateral bridge section, by this strength is added to the structure. The fenders  3  are only tall enough to allow for wheel clearance, these fenders  3  along with the deck material are a non slip surface such as diamond or tread plate of proper strength to support the intended load, ATV&#39;s and the like are able to drive over these fenders  3  when loading and unloading. 
     Fenders  3  may be flanged on the edges that run parallel to the bridge frame, both the inside and outside edge to increase strength, fenders  3  are crowned to accommodate the wheel clearance and may have be bent slightly on there ends to attach to member  32 , the upper wishbone frame, there is a frame member  32  both in front and behind the wheels  36  as seen in  FIG. 4  represented by a dashed line, the deck  2  is hinged  14  and lays flat on the deck frame seen in  FIG. 1 , these decking plates  3  located both behind and in front of the wheel fenders  3 .  FIG. 1  shows that the corners of the trailer and decking are rounded, this giving a better way to deflect brush or trees when traveling off road, and better aerodynamics on the road. 
     In  FIG. 2  you see member  4 , this acts as a wheel stop or safety stop, member  4  is attached to the front wishbone frame on one side extending vertical to above the deck bent 90 degree&#39;s and travels horizontally to the opposite side and then 90 degrees down to the wishbone frame members  32  of opposing side, the level it travels horizontally is the same height as member  1  and is attached, this being a wheel guide bar  1 , this guard bar  1  is used to guide the inside of the wheels of an ATV or like from damaging the storage box  10  that extends above the deck surface, buy guiding the inside of the wheels when loading and unloading,  10  will typically be 6-7″ above deck  3  level depending of the vehicle it&#39;s designed to transport. 
     In  FIG. 5  member  40  is shown as a vertical support, for guard bar  1  at the rear of the trailer, in  FIG. 5  you also see the storage box  10  and members  26 , item  26  shown on each side of the storage box are loading ramps  26 , also notice the box is narrower than the gap in the trailer, this area on each side of the box allows the space for stowing these ramps  26 , the ramps  26  are laid on there side, in a vertical position, and slid in the back of the trailer in ramp channels  25  shown in blow-up picture on  FIG. 5 , these ramp channels  25  are formed sheet metal the length of the rams  26  also being and are welded or attached to the trailer frame. This unique ramps storage allows you to access the ramps when the trailer is loaded. 
     Below deck storage enclosures  16  are found below all four deck  2  sections, these are in front and behind the fenders  3  on both sides of the trailer, these enclosures  16  are made of vacuum formed plastic or fibber glass. In  FIG. 2  these enclosures  16  conform to the outside shape of the trailer and are attached to frame member  37  at deck  3  level and go down from there wrapping around to the bottom side to the upper bridge frame member  29 , enclosures  16  on fender  3  side edge, extend up and attach to wishbone frame member  32 , attaching is by means of rivets or screws, these storage  16  enclosures are shaped or formed to cover four sides and the bottom, having rounded corners, the rear below deck enclosures  16  are recessed to accommodate the tail light/turn signals  17 , tail lights are recessed within the frame profile as to not be vulnerable to breakage. 
       FIG. 2  and  FIG. 4  show a ramp retainer  9 , this ramp retainer  9  is made of a formed steel rod, and welded to lower section of member  37 , allows a place to attach the ramps  26  while loading or unloading, the ramps  26  will have a cleat on the end, and parallel to the end facing down, that will engage in the slot formed by ramp retainer  9 . 
     Member  10  is a storage box that can be removed, having a hinged lid  13 , this box has a width that fills the gap bed leaving just enough room on each side to accommodate the ramp channels  25  and ramps, length of ramps  26  &amp; ramp channels  25  being the same length. 
       FIG. 2  shows a hinged  15  cover  18  directly in front of the box  10 , this cover  10  is mounted on the guard bar  1 , being hinged  15  on one side, and held closed on the opposite side by means of a typical latch, this cover  18  has two edges that are flanged down, perpendicular to the hinged side for added strength, this covers the remainder of the gap bed forward of the box. Sheet metal box is used to enclose the remainder of this storage area bellow the cover  18 , having 4 sides and a bottom with the sides having at least some vents. 
     The gap bed trailer takes advantage of ground clearance (ground to frame/drive train, without interference) of an ATV, this embodiment of a raised center, could be achieved also by a unibody design, by making the box a heavier or stronger design mounted directly to the axle and tongue, and use this as the frame of the trailer, adding wishbone frame work to the side of the box, rather than a tubing frame structure, maintaining storage space both above and bellow the trailer deck, this deck could also be made solely out of hinged storage boxes, and these are attached to the side of the main center box, resulting in another version consistent with the objects of this invention. With ATV&#39;s being made in various sizes and shapes, wheel sizes could also be changed to the point that a flat top deck could be used without the need for fenders, along with side bellow-deck storage could also be eliminated for a more cost effective version. 
     The foregoing description of the preferred embodiment of the invention has been presented for the purpose of illustration and description. Not being the exhaustive or limit of the invention to the precise form described. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention be limited not by detailed description alone, but rather in conjunction with the claims appended hereto.
