专利汇可以提供Amphibious apparatus for conventional land aircraft专利检索，专利查询，专利分析的服务。并且An improved float assembly is adapted to conveniently attach to the existing landing gear of a conventional land-type aircraft and includes a centrally positioned primary float structure which attaches to the existing landing gear struts and includes secondary or stabilizing float structures which attach to the existing axles for the ground-engaging wheels of the landing gear. Directional control for steerage while waterborne is aided by a water rudder on the primary float which is operated from the steering mechanism of the conventional landing gear.，下面是Amphibious apparatus for conventional land aircraft专利的具体信息内容。
1. Amphibious landing gear apparatus for an aircraft which includes a pair of laterally spaced fixed landing gear struts having axles near the lower ends thereof for rotatably mounting ground-engaging wheels thereon and which includes an additional wheel strut located in a central position along the length of the aircraft for rotatably mounting a third ground-engaging wheel thereon, the apparatus comprising: a primary buoyant body attached to the laterally spaced landing gear struts and to a wheel strut centrally located along the length of the aircraft; and a pair of stabilizing buouyant bodies disposed to attach to the axles near the lower ends of the laterally spaced landing gear struts.
2. Apparatus as in claim 1 comprising: support means attached between said primary buoyant body and the laterally spaced landing gear struts at selected locations along the lengths thereof and between said body and said wheel strut for providing at least three-point suspension of said primary buoyant body with respect to said aircraft; and said primary buoyant body having a planing surface on the underside thereof which is disposed lower than the underside surfaces of the laterally spaced buoyant bodies for providing substantially the entire water-contacting support surface about takeoff and landing speeds of the aircraft.
3. Apparatus as in claim 2 wherein: said support means attached between said body and the wheel strut is rotatable about an axis in response to steerage rotation of said wheel strut of the aircraft; a water-engaging rudder disposed near the trailing end of the primary buoyant body; and means coupled between said support means attached to said wheel strut and the water-engaging rudder for angularly positioning said rudder in response to steerage rotation of said wheel strut of the aircraft.
4. Apparatus as in claim 3 wherein said wheel strut is centrally located forward of said laterally spaced landing gear struts, and resilient means support said primary buoyant body with respect to the laterally spaced landing gear struts.
5. Apparatus as in claim 1 comprising a pair of ground-engaging wheels carried by said primary buoyant body in alignment along the length of said body, one of said wheels being located near the forward end of said body and the other of said wheels being located near the transverse axis of the axles carried by the landing gear struts of the aircraft.
6. Apparatus as in claim 5 comprising: a ground-engaging wheel carried by each stabilizing buoyant body near the trailing end thereof; and means coupled to rotate said stabilizing buoyant bodies about the axles near the lower ends of said landing gear struts for positioning said wheels carried by said stabilizing buoyant bodies at substantially common planar elevation with respect to the ground-engaging wheels carried by the primary buoyant body.
7. Apparatus as in claim 6 comprising actuating means coupled to the ground-engaging wheels carried by said primary buoyant body for selectively extending and retracting said wheels and simultaneously rotating said stabilizing buoyant bodies to extend and retract the wheels carried near the trailing ends thereof with respect to the common planar elevation of the wheels carried by the primary buoyant body.
8. Apparatus as in cLaim 1 comprising a pair of resilient support means attached to said primary buoyant body and disposed to be attached to the laterally spaced landing gear struts of the aircraft at locations along the exposed lengths thereof between the remote ends near said axles and the proximate ends adjacent the fuselage of the aircraft.
