| 权利要求 | 1. In a helicopter comprising a main body section, a plurality of struts for supporting said main body section when the helicopter has landed, and load attachment means on the lower surface of said main body portion for carrying a load positioned intermediate said struts, the improvement comprising: a cockpit mounted on said main body section and means for adjusting the vertical elevation of said cockpit between a first position in a substantially horizontal plane with said main body portion and a second position substantially below said main body section. 2. The helicopter of claim 1 wherein said adjusting means comprises a plurality of link means forming a geometric figure, and means attached to said plurality of link means for altering the shape of the geometric figure. 3. The helicopter of claim 1 including a connecting section intermediate said main body section and said cockpit, said adjusting means extending through said connecting member. 4. The helicopter of claim 3 including ladder means within said connecting section comprising a plurality of steps and means interconnecting said steps for maintaining the foot-contact surface of each step in a horizontal plane in all positions of vertical elevation adjustment of said cockpit. 5. The helicopter of claim 1 wherein said second position is adjacent the ground surface when said helicopter has landed. 6. A helicopter comprising a main body fuselage, propulsion means mounted on said fuselage, a cockpit attached to said fuselage, adjustable means connecting said cockpit to said fuselage for adjusting the position of said cockpit relative to said fuselage, said adjustable means comprising a plurality of link means pivotally connected together so as to form a parallelogram, and means for varying the shape of the parallelogram foRmed by said link means. 7. The helicopter of claim 6 wherein said varying means comprises a hydraulic cylinder attached to one of said link means of the parallelogram and a piston rod extending telescopically from a position within said cylinder and attached to another of said link means in the parallelogram. 8. A helicopter comprising a main body fuselage, propulsion means mounted on said fuselage, a cockpit attached to said fuselage, adjustable means connecting said cockpit to said fuselage for adjusting the position of said cockpit relative to said fuselage, and means in said adjustable connecting means providing passage means for personnel moving through said connecting means between said cockpit and said main body fuselage. |
