Abstract

Abstract A model airplane is provided with an upwardly extending recess in the rearward portion of the fuselage, and the recess terminates in a point-receiving conical depression. The recess is generally aligned longitudinally with the center of gravity of the model, and the conical depression is located above or approximately at the center of gravity. Adjustable weights may be carried in the wings or other parts of the model to permit the center of gravity of the airplane to be varied longitudinally so that the center of gravity can be precisely positioned relative to the recess. The support stand includes a base and a flexible, resilient, curved spring metal band or sheet which is secured to the base and extends arcuately upwardly therefrom. An elongated support needle is secured to the upper end of the band, and the needle extends into the recess in the model and terminates in a point which is received by the conical depression. The model is thereby supported on the point of the needle, and the flexible, resilient band and the point support permit the model to undergo a variety of movements under the influence of air drafts or other forces to provide realistic simulation of the movements of a real airplane.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 154 words
In combination, a model and support stand therefor, the model having an elongated body provided with a recess terminating in a point-receiving depression, the support stand having a base, a flexible, resilient spring band extending arcuately from the base and having a pair of ends, the band being formed from an elongated flat strip of metal having a pair of co-planar flat surfaces, the width of the band being substantially greater than the thickness of the band whereby the band resists being twisted about the longitudinal dimension thereof, the band being bent into a bow shape extending generally perpendicularly to the flat surfaces of the band, one end of the band being attached to the base, a support needle attached to the other end of the base and extending into the recess, the support needle terminating in a point received by said depression whereby the model is supported by the point of the needle.
Claim 2
Dependent Claim 154 words
In combination, a model and support stand therefor, the model having an elongated body provided with a recess terminating in a point-receiving depression, the support stand having a base, a flexible, resilient spring band extending arcuately from the base and having a pair of ends, the band being formed from an elongated flat strip of metal having a pair of co-planar flat surfaces, the width of the band being substantially greater than the thickness of the band whereby the band resists being twisted about the longitudinal dimension thereof, the band being bent into a bow shape extending generally perpendicularly to the flat surfaces of the band, one end of the band being attached to the base, a support needle attached to the other end of the base and extending into the recess, the support needle terminating in a point received by said depression whereby the model is supported by the point of the needle.
Claim 3
Dependent Claim 30 words
The structure of claim 1 in which the band includes a pair of sides which converge from said one end of the band toward the other end of the band.
Claim 4
Dependent Claim 21 words
The combination of claim 1 in which the point-receiving depression is positioned at approximately the center of gravity of the model.
Claim 5
Dependent Claim 32 words
The structure of claim 1 in which the recess is frusto-conical and converges upwardly whereby the model can tilt about the support needle without interference from the side waLl of the recess.
