DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to models in general, and more specifically to flying model airplanes with attachments allowing positive assembly and dissembly of component parts.
BACKGROUND ART
Model airplanes have been known and in common use almost since the time that engine driven aircraft became a reality. Flying models have been popular and have, in the past, been fabricated of a balsa wood structure covered with fabric or thermoplastic material, hollow, or solid expanded plastic, such as urethane foam and blown polystyrene beads, also, flat wood, or plastic sheet, etc., each representing either a specific aircraft or a derivation thereof. Flying model airplanes have also been powered by twisted rubber bands, gasoline, or electric motors, compressed gas, or rocket type thrusters in many styles and configurations, each attempting to simulate flight using the basic aerodynamic principles of an original craft. Prior art has been attempting to achieve a number of different goals, that of scales miniaturization and optimum flying qualities, regardless of appearance. The instant invention is directed to an approach that is inexpensive enough to be practical and, yet, have sufficient structural integrity to function efficiently with enough shape to allow detail to be illustrated projecting the feel and general appearance of the original aircraft. Further, the invention allows easily removable structural joining of component parts heretofore unavailable in the combination thus disclosed.
DISCLOSURE OF THE INVENTION
Since model airplanes powered by rubber bands or direct current electric motors must, by their very nature, be extremely light and fragile, the problem of assembly and dissembly has plagued model builders. It is, therefore, the primary object of the invention to provide a model that is fabricated of a thin foam thermoset material with junctions to the major components so interrelated that only two connections need to be made to assemble or dissemble all of the major elements. This is accomplished by mating the wing to the fuselage and inserting the landing gear into an eye that is directed through a reinforced interlocking member in the wing tieing all three members securely together. The tail is similarly joined with the elevator juxtapositioned on the top of the fuselage and the vertical stabilizer having a projecting finger interface with an inverted dovetail on the body. Again, three elements are connected together using an integral reinforced joint.
An important object of the invention uses a triangular fuselage with two sides bonded together and a separate bottom inserted between the sides creating a strong body that not only has integrity of stiffness, but also gives depth to the thin material. Further, the triangular shape is slightly below the top outline of the fuselage allowing the cockpit area to extend above, giving further appearance of width relationship simulating the actual aircraft structure.
Another object of this triangular shape lends the model to have the details printed or silk screened on the outside surface of each side. These details outline features of the aircraft, such as cockpit structure, engine exhaust, access doors, rivet lines, engine cowl, and the like. The printing is easily accomplished in the flat prior to assembly making the procedure easy and fast to accomplish.
Still another object of the invention allows the flat material to be bent in an aerodynamic shape forming the wing to give lift to the surface. This shape is maintained by the matching cutout in the fuselage and is easily preserved as the attachment is made in this area and the rear portion is interlocked into a cutout.
Yet another object of the invention allows the model to be propelled by either twisted rubber bands, or an electric motor, with equal ease, and since the fuselage is hollow, the elements are located within covering the apparatus completely. This arrangement does not distract from the physical appearance of the airplane, as the outside is not unencumbered with the
