Abstract

Abstract A model aircraft kit which enables the purchaser to assemble a variety of model aircraft configurations and planforms, uses a relatively small number of components. The components of the model aircraft kit comprise at least one of several possible variations of fuselages, a wing panel or panels, and a number of stabilizing and control surfaces which may include conventional or diagonally hinged control surfaces. Releasable connectors which may include a pair of releasable wing tip appendage connectors, are used to join the components thereby providing a wide variety of planforms and configurations. At least one of the fuselages is capable of being separated into subparts one of which becoming a short fuselage being capable of accommodating some or all of the remaining components of the model aircraft kit. Several individually unique model aircraft are assembled using a pair of wing tip appendage connectors with respecting stabilizing surfaces, independent of other multiple configuration features of the aircraft kit.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 240 words
A model aircraft kit including constituent parts which are adapted to be assembled together in connected relationship in differing model aircraft configurations providing correspondingly different model aircraft appearances and aerodynamic characteristics, comprising: fuselage members, at least one of said fuselage members comprising a body including means by which some of said parts can be assembled thereto, comprising slots, grooves, notches, and surfaces thereon and therein in combination serving as releasable supports for at least some of said parts, said one fuselage member thereby being adapted for supporting other of said constituent parts, said one fuselage member further comprising at least two unitary subparts, each having means adapting it to be detachably joined to the other anyone of said subparts being adapted to function, when detached, as a separate fuselage in one of said configurations; a plurality of plane surface members for providing differing planforms for said configurations, each of said plurality of plane surface members being adapted to be generally supported by at least one of said fuselage members, at least some of said plurality of plane surface members being adapted to support another of said plurality of plane surface members; and connector means for connecting at least some of said plurality of plane surface members to at least some of said fuselage members at differing positions and for connecting one or more of said plurality of plane surface members to another one of said plurality of plane surface members.
Claim 2
Dependent Claim 240 words
A model aircraft kit including constituent parts which are adapted to be assembled together in connected relationship in differing model aircraft configurations providing correspondingly different model aircraft appearances and aerodynamic characteristics, comprising: fuselage members, at least one of said fuselage members comprising a body including means by which some of said parts can be assembled thereto, comprising slots, grooves, notches, and surfaces thereon and therein in combination serving as releasable supports for at least some of said parts, said one fuselage member thereby being adapted for supporting other of said constituent parts, said one fuselage member further comprising at least two unitary subparts, each having means adapting it to be detachably joined to the other anyone of said subparts being adapted to function, when detached, as a separate fuselage in one of said configurations; a plurality of plane surface members for providing differing planforms for said configurations, each of said plurality of plane surface members being adapted to be generally supported by at least one of said fuselage members, at least some of said plurality of plane surface members being adapted to support another of said plurality of plane surface members; and connector means for connecting at least some of said plurality of plane surface members to at least some of said fuselage members at differing positions and for connecting one or more of said plurality of plane surface members to another one of said plurality of plane surface members.
