专利汇可以提供Aircraft pants structure专利检索，专利查询，专利分析的服务。并且A wheel pants structure is provided for aircraft having landing gear including wheel and axle means which are supported in a substantially fixed position relative to the aircraft fuselage. The pants structure is in the form of a housing defined by fixed wall means having an opening therein adapted to be closed by a pair of pivotal door elements. The housing means including the fixed wall means and the door elements is adapted to completely enclose the wheel when the door elements are in the closed positions thereof. When the door means are moved to the open positions thereof, a portion of the wheel means is exposed for engagement with an underlying support surface for the aircraft. The door means may be moved between the open and closed positions thereof mechanically, electrically, hydraulically or pneumatically and may be actuated either manually from within the aircraft cabin or automatically.，下面是Aircraft pants structure专利的具体信息内容。
1. A pants structure for aircraft having landing gear means including axle and wheel means, comprising housing means for said wheel means, said housing means including wall means substantially fixed relative to said axle and wheel means and door means movable between first and second positions relative to said fixed wall means, said fixed wall means and said door means enclosing said wheel means when said door means is in one of said first and second positions, a portion of said wheel means being exposed to engage an underlying support surface for said aircraft when said door means is in the other of said first and second positions, means supporting said door means for pivotal movement relative to said fixed wall means, means to move said door means between said first and second positions, said door means including a pair of door elements, said means supporting said door means including door lever means for each door element, means intermediate the opposite ends of said door lever means supporting said door lever means for pivotal movement relative to said fixed wall means, and one of said opposite ends of each of said door lever means being interconnected with one of said door elements.
2. The pants structure of claim 1, wherein said means to move said door means includes means operable to substantially simultaneously pivot said door lever means to move said door elements.
3. The pants structure of claim 2, wherein said means to pivot said door lever means includes second pivotal lever means, link means between said second lever means and the other of said opposite ends of each of said door lever means, and means to pivot said second lever means for said link means to cause said door lever means and thus said door elements to pivot relative to said fixed wall means.
4. The pants structure of claim 3, wherein said means to pivot said second lever means includes pivotal shaft means, said second lever means being attached to said shaft means for pivotal movement therewith, and actuator means to pivot said shaft means including actuator control means operable from within said aircraft.
5. The pants structure of claim 4, wherein said actuator means includes an actuator lever having one end thereof connected to said shaft means and actuator cable means including cable means having one end thereof connected to the other end of said actuator lever, the other end of said cable means being connected to said actuator control means.
6. A pants structure for aircraft having landing gear means including axle and wheel means, comprising housing means for said wheel means, said housing means including wall means substantially fixed relative to said axle and wheel means and door elements movable between first and second positions relative to said fixed wall means, said fixed wall means and said door elements enclosing said wheel means when said door elements are in one of said first and second positions, a portion of said wheel means being exposed to engage an underlying support surface for said aircraft when said door elements are in the other of said first and second positions, support and actuator means for said door elements within said housing means, said support and actuator means including support plate means attached to said fixed wall means, a door lever for each door element pivotally attached intermediate its opposite ends to saId plate means, one end of each door lever being connected to one of said door elements whereby pivotal movement of each door lever in opposite directions moves the corresponding door element between said first and second positions thereof, shaft and lever means mounted on said plate means for pivotal movement about an axis transverse to the pivot axes of said door levers, said shaft and lever means including a lever element corresponding to each door lever, link components between each lever element and the other of said opposite ends of the corresponding door lever, and means to pivot said shaft and lever means for said lever elements and link components to impart pivotal movement to said door levers and thus said door elements.
7. The pants structure of claim 6 wherein said door levers are pivotal about a common pivot axis.
8. The pants structure of claim 6, wherein said means to pivot said shaft and lever means includes an actuator lever having one end thereof attached to one end of said shaft and lever means and actuator cable means including cable means having one end thereof connected to the other end of said actuator lever, and cable actuator means connected to the other end of said cable means.
9. The pants structure of claim 8, wherein said support plate means is disposed in said housing means forwardly of said wheel means and in a plane substantially parallel to the axis of said wheel means.
10. The pants structure of claim 9, wherein pivotal movement of said door levers is in opposite directions with respect to said common pivot axis.
11. The pants structure of claim 10, wherein the axis of said lever and shaft means is substantially parallel to the axis of said wheel means, whereby pivotal movement of said door levers and thus said door elements is in a direction axially of said axis of said wheel means.
12. The pants structure of claim 11, wherein said door elements have edges adjacent one another when said door element are in said one of said first and second positions, and seal means on the inner surface of one of said door elements and overlying the joint between said adjacent edges.
13. The pants structure of claim 12, and sealing means on the inner surface of said fixed wall means and covering the joint between said fixed wall means and door elements when said door elements are in said one of said first and second positions.
14. The pants structure of claim 12, wherein said adjacent edges are contoured longitudinally so as to overlap one another.
15. A pants structure for aircraft having substantially fixed landing gear means including axle and wheel means, comprising housing means for said wheel means, said housing means including wall means having an opening therein having a peripheral edge, a portion of said wheel means extending below said edge, said housing means further including a pair of door elements movable to a first position to close said opening and cover said extended portion of said wheel means and movable to a second position to expose said wheel means sufficiently for said wheel means to engage a supporting surface for said aircraft, means to move said door elements between said first and second positions thereof, seal means carried by said wall means inside said housing means for covering the joint between said peripheral edge of said opening and said door elements when said door elements are in said first position, said door elements having adjacent edges overlapping one another when said door elements are in said first position, and a seal strip carried by one of said door elements on the inner surface thereof and extending beyond the corresponding edge of the door element to cover the joint between said adjacent edges of said door elements when said door elements are in said first position.
