Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to maintenance platforms, and more particularly relates to a mobile maintenance platform with features that facilitate access to airplane components. 
       BACKGROUND 
     Description of the Related Art 
       [0002]    The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. 
         [0003]    The following is an example of a specific aspect in the prior art that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. There exist many implements for facilitating aircraft maintenance, overhaul, repair, inspection or modification, but implements designed for many specific purposes are lacking, including implements for removing and replacing tires, inspection plates, spark plugs, checking cylinder compression, removal and replacement of fuses, light bulbs, refueling, and washing windows. 
         [0004]    Typically, aircraft maintenance stands fall into three categories: phase maintenance stands for depot-level maintenance, daily maintenance stands, and multi-application work stands. The type of required maintenance dictates the type of work platform required, and the level of skill that a mechanic must have. 
         [0005]    It is known in the aviation industry that aviation structural mechanics maintain aircraft airframe and structural components, flight surfaces, as well as maintaining hydraulic and pneumatic controls and actuating systems and mechanisms. The mechanics may also service landing gear systems, perform engine maintenance, air conditioning, pressurization, visual improvement, oxygen and other utility systems, egress systems, including seat and canopy ejection systems and components. Such detailed work requires facilitated access to the airplane component, which often rest at a high elevation. This work must be done in a safe efficient manner. 
         [0006]    Mechanics need to be able to service the aircraft from a work platform reaching elevated regions of the aircraft. Suitable, safe and efficient platforms are lacking in the art. A work platform which can be configured to position in proximity to the airplane component, yet maintain a buffer to prevent bumping into the airplane component, is desirable and necessary to prevent damage to the aircraft. The work platform provides access to any tools, liquids, equipment, communication devices, and publications the mechanic may need, as well as access to the portion of the airplane which needs to be inspected and/or maintained. 
         [0007]    In view of the foregoing, it is clear that these traditional maintenance platforms leave room for more optimal approaches. 
       SUMMARY 
       [0008]    From the foregoing discussion, it should be apparent that a need exists for an apparatus and method for improving safety and efficiency of aircraft engine maintenance. Beneficially, such an apparatus and method would provide a plurality of features and components to facilitate access to aircraft, while also providing a safe, efficient working surface. 
         [0009]    The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available apparatus. Accordingly, the present invention has been developed to provide an apparatus and method for servicing aircraft and vehicles that overcome many or all of the above-discussed shortcomings in the art. 
         [0010]    The apparatus for servicing the at least one vehicle includes a plurality of modules configured to functionally execute the necessary steps of accessing vehicle components from the maintenance platform and providing a safe and adjustable working surface. In some embodiments, the apparatus comprises a mobile maintenance platform disposed to position in proximity to at least one vehicle, such as an airplane, for servicing and manufacturing. However, the present invention may also be operable to join with a stationary object for performing maintenance, including, without limitation, inspection, repairing, welding, changing parts, examining, sandblasting, and painting. The at least one vehicle may include, without limitation, an airplane, a boat, a semi-truck, an oil derrick, a drilling barge, and a hot air balloon. Those skilled in the art, in light of the present teachings, will recognize that the maintenance platform can be temporarily positioned to a desired location on the vehicle, without requiring welding, and is, thus, not subjected to the same restrictions as permanent maintenance platforms. The maintenance platform can be quickly, adjustably and removably located adjacent to any vehicle component, independent of the specific dimensions and/or structural characteristics thereof. 
         [0011]    In one embodiment of the present invention, the apparatus includes a modular deck where a significant portion of the maintenance occurs. The deck is disposed in a substantially horizontal plane, efficacious for supporting a plurality of workers, maintenance equipment, power, work lighting, vehicle components, and accessories.

In one embodiment, the deck includes a coating, which may be configured to be at least partially slip resistant. The coating may include, without limitation, slip resistant diamond deck, rubber, thermally stable polyethylene terephthalate, protruding members, magnets, and adhesives. Those skilled in the art, in light of the present teachings, will recognize that vehicle maintenance often involves working with oils and small, round fasteners, thereby creating a slippery surface on the deck. Further, the maintenance platform often rises a substantial distance over the ground surface, whereby slipping and falling off the maintenance platform can cause serious personnel injury or tool damage. The deck may comprise adjustable, telescopic, slidable and/or removable platform components for adjusting the size and shape of the deck for specific purposes. In some embodiments, a detachable or fixed railing is disposed to form a safety barrier around a peripheral edge of the deck. The railing may telescopically extend and retract, vertically or horizontally, to a desired size and dimension, for the purpose of safety and fall protection. The railing includes hand grips to allow a worker to grasp while servicing the at least one vehicle. The railing may also include storage compartments for holding tools and parts pertinent to servicing the at least one vehicle. The railing may detach completely from the deck when not in use, or during transport. In other embodiments, the railing may extend and retract from the deck or the side of the deck. The railing may locked in a desired position using a fastener. An adjustable extension leg may join with the railing, allowing access from a ground surface to the deck. The adjustable extension leg may comprise a ladder ship&#39;s ladder, staircase, escalator or elevator that is configured to provide access to the deck. In those embodiments comprising ladders or staircases, spacing between the steps or stairs is maintained evenly as the extension leg is adjusted. In some embodiments, the deck includes an integrally formed at least one gap on at least one edge of the deck. The at least one gap provides a space for encompassing a vehicle component, whereby the maintenance platform may move closer to the vehicle component. The vehicle component may include, without limitation, an airplane engine, a wing, a support frame, landing gear, and a building. One or more sliding platforms are positioned on either side of the at least one gap. The sliding platform(s) are configured to adjustable slide into position adjacent to an aircraft engine or fuselage. The sliding platforms slide in plane with the deck, forming a substantially planar surface extendable and retractable to augment or mitigate the size of the at least one gap. 
         [0012]    In a further embodiment, the apparatus includes a modular frame. The frame provides a lightweight structure that joins beneath the deck for support. The frame may comprise a plurality of tensile and compression support members, such as bars, rods, angles, beams, channels and tubes. In some embodiments, the frame may be configured to provide different amounts of support members so as to adjustably change in size, shape, and dimension. The modular configuration of the frame allows for easy construction or flexible arrangement. A plurality of fasteners secures the plurality of support members into a desired size, shape, and dimension. The plurality of fasteners may include, without limitation, quick connect t-pins, latches, rivets, screws, bolts, adhesives, and magnets. Suitable materials for fabricating the frame may include, without limitation, aluminum, steel, metal alloys, fiberglass, and high density polymers. In some embodiments, the frame may include a transport portion for moving the maintenance platform. The transport portion may include, without limitation, casters, rubber wheels, rails, and tracks. The transport portion may be adjustably lowered for engaging the ground surface, and raised for storage. In yet another embodiment, a tow portion may join with the frame.

         [0013]    In one embodiment of the present invention, the apparatus includes at least one leg. Each leg extends in a substantially vertical orientation from the ground surface. The at least one leg may telescopically adjust for elevating to a desired height for servicing the at least one vehicle, positioning around a vehicle component, and/or allowing the transport portion to engage the ground surface. In one embodiment, the maintenance platform may elevate up to thirty inches. An adjustable hand crank powers the elevation of the deck. However, in other embodiments, the elevation may be automatic. However, greater heights may be achieved in additional embodiments. At least one jack may lift and lower the maintenance platform to a desired height. Those skilled in the art, in light of the present teachings, will recognize that the deck, the maintenance workers, the vehicle components, the tools on the deck, and the frame may combine to form a heavy load. The at least one jack is efficacious in applying sufficient force to support and elevate the heavy load. The at least one jack may include, without limitation, a five ton screw jack, a pneumatic jack, or a hydraulic jack. A jack connection bar may join a pair of the jacks to provide a multiplier effect when the pair of jacks lifts very heavy loads.
