ABSTRACT:
A folded glider is comprised of a sheet of material having a center hinge line which is located along its medial axis and paired side hinge lines which are located generally parallel to the center hinge line at spaced intervals outwardly therefrom. A slit is located in the sheet of material, extending transversely between the side hinge lines proximate the trailing edge of the glider. The glider is formed by folding the sheet of material upwardly along the portion of the center hinge line lying forwardly of the slit to form a fuselage, folding it downwardly along the portions of the side hinge lines lying forwardly of the slit to form wings, and folding it upwardly along the portions of the side hinge lines lying rearwardly of the slit and downwardly along the portion of the center hinge line lying rearwardly of the slit to form an inverted "V"-shaped vertical tail. In another embodiment of the glider, the side hinge lines do not extend forwardly of the slit so that when the glider is folded, the wings and fuselage remain coplanar. A third embodiment has two parallel sets of side hinge lines allowing tighter folding of the glider along the center hinge line to alter its weight distribution. Another embodiment has the slit angled rearwardly between each side hinge line and the center hinge line so that the resulting triangle it outlines can be folded forwardly to shift the center of gravity of the glider toward its leading edge. In several of the embodiments the glider is shaped so that a plurality of them can be fabricated from a single sheet of material with little or no wastage of material.
