US Patent 4204358 – Aluminum model airplane kit (May 27, 1980)
A motorized model vehicle is formed of sheets of aluminum attached by heat soluble glue. The model has no internal supporting structure, but relies upon the resilient prestress of the metal sheet to maintain a desired shape. Methods of folding, forming, connecting and strengthening the parts of the aluminum body are disclosed.
Description
(1) Field of the Invention
This invention relates to model vehicles and to kits for building model vehicles, particularly model airplanes.
(2) Description of the Prior Art
Model vehicles and especially model airplanes are of two types. The first type is constructed of balsa wood or other light wood. Many structural supports are provided, with the balsa being covered by fabric or other lightweight covering.The second type is a molded, plastic shell joined with styrene glue, etc., to form a rigid frame which may be easily assembled and joined together.
However, even with the use of balsa wood and plastic, such model airplanes or model vehicles are still relatively heavy. The use of balsa and/or plastic requires a great deal of time to assemble and are relatively fragile. Balsa and plastic are relatively fragile, and damaged parts must ordinarily be replaced with new ones instead of repairing the old. Such models also tend to shatter upon impact with solid objects, and to be unusable until repaired.Read more about Aluminium model airplane kits patent.
