<P>PROBLEM TO BE SOLVED: To provide a lock opening/closing device for aerial delivery of a cargo for solving the failure of a lock opening/closing mechanism occurring during the aerial delivery by the lock opening/closing mechanism employing a multiplexed parachute load detector and operating part for opening and closing a lock, a pair of pawl parts for locking reciprocally reversed, facilitated mounting of a load device for an individual testing of a lock opening/closing function or the like. <P>SOLUTION: In the lock opening/closing device to hold/release the cargo in/from an airplane for the purpose of the aerial delivery as loading the cargo in the airplane, a parachute load for taking out the cargo applied to the device is separately measured with the three load detectors. A signal processing system is provided to compare output signals of the detectors, and adopt one of the most appropriate output signal of the load detector as the signal for releasing the lock by way of majority decision. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は航空機の貨物空中投下用ロック開閉技術に属する。
【0002】
【従来の技術】
本発明のような貨物空中投下用ロック開閉技術は、少なくとも国内には無い。
【0003】
【発明が解決しようとする課題】
飛行中の航空機から貨物を投下するには、まず当該貨物に直結したパラシュートを空中後方に放出し開傘させる。ロック開閉装置にかかるパラシュート力が設定値以上になると、それまで貨物固定していたロックが開放され、貨物はパラシュート力で機体後方に引き出される。このロック開閉装置がもし空中投下中に故障を起こせば、航空機は極めて危険な状況に陥る。このため同装置には極めて高い信頼性と、日常的に実施可能な機能検定の容易さが求められる。
【0004】
【課題を解決するための手段】
パラシュート荷重検出器及びロック開閉用作動部品の多重化、相互に反転するペアのロック用爪部品、ロック開閉機能の個別検定用負荷装置の取付け容易化等を採用したロック開閉機構により解決できる。
【0005】
【実施例1】
図1のように、外力(パラシュート荷重)1が負荷されると、ロック用爪部品(A)2、リンク4,5,6,7を介してパラシュート荷重検出器8,9,10が押される。8,9,10の出力信号は信号処理器11に入力される。8,9,10の出力信号値は本来ほぼ同じであるべきであるが、異なる場合もある。これらの信号の内、最も確からしい信号が11により判定される。この信号値が設定値以上になるとロック開閉用作動部品12が延伸し、5,6がばね13の力に抗して回転することにより2が時計方向に回転する(即ちロックが解除される)。ロック用爪部品(B)3はリンク(A)4により、2が回転すると同時に反時計方向に回転する。2に突起点をつけ1が負荷される場所が常に同じになるようにする。11は外部指令信号15により12の復元信号、及び12の作動を確認するためのテスト信号を出す機能も有する。2〜7の動きはストッパー14により制限される。12は多重の(即ち2個以上の同じ部品から構成される)場合もある。13は無い場合もある。ロック開閉機能検定用負荷装置16が容易に取付けられるように筐体17に取付け点18を設ける。
【0006】
【実施例2】
図2のように、実施例1におけるパラシュート荷重検出関連部品(8,9,10、16及び18)がない場合である。15によりロックの開閉のみを行う。1に起因する摩擦力によりロック解除が阻害されない利点がある。
【0007】
【発明の効果】
本発明により、信頼度が高くかつ機能検定の容易な空中投下用ロック開閉装置が実現できる。
【図面の簡単な説明】
【図1】本発明の一例として、実施例1で記述したロック開閉機構の概念図である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock opening / closing technique for airborne cargo release of an aircraft.
[0002]
[Prior art]
There is no lock opening / closing technology for aerial release of cargo as in the present invention at least in Japan.
[0003]
[Problems to be solved by the invention]
To drop cargo from an aircraft in flight, the parachute directly connected to the cargo is first released into the air and opened. When the parachute force applied to the lock opening / closing device is equal to or greater than a set value, the lock fixed to the cargo is released, and the cargo is drawn out to the rear of the aircraft by the parachute force. If this locking device fails during airdrop, the aircraft will be in a very dangerous situation. For this reason, the device is required to have extremely high reliability and ease of function verification that can be performed on a daily basis.
[0004]
[Means for Solving the Problems]
The problem can be solved by a lock opening / closing mechanism employing a multiplexing of a parachute load detector and a lock opening / closing operation component, a pair of reversing pairs of locking claw components, and easy mounting of a load device for individual verification of a lock opening / closing function.
[0005]
Embodiment 1
As shown in FIG. 1, when an external force (parachute load) 1 is applied, parachute load detectors 8, 9, and 10 are pushed via locking claw parts (A) 2 and links 4, 5, 6, and 7. . The output signals of 8, 9, and 10 are input to the signal processor 11. The output signal values of 8, 9, and 10 should be essentially the same, but may be different. Of these signals, the most probable signal is determined by 11. When the signal value becomes equal to or greater than the set value, the lock opening / closing operating component 12 is extended, and 5 and 6 rotate against the force of the spring 13 so that 2 rotates clockwise (that is, the lock is released). . The lock claw part (B) 3 is rotated counterclockwise at the same time as the rotation of 2 by the link (A) 4. A projection point is provided on 2 so that the place where 1 is loaded is always the same. Reference numeral 11 also has a function of outputting a 12 restoration signal and a test signal for confirming the operation of 12 by the external command signal 15. The movements 2 to 7 are restricted by the stopper 14. 12 may be multiplexed (ie, composed of two or more identical parts). 13 may not be present. An attachment point 18 is provided on the housing 17 so that the lock opening / closing function test load device 16 can be easily attached.
[0006]
Embodiment 2
As shown in FIG. 2, there is no parachute load detection related components (8, 9, 10, 16 and 18) in the first embodiment. 15 is used to open and close the lock only. There is an advantage that unlocking is not hindered by the frictional force caused by (1).
[0007]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, the lock opening / closing apparatus for aerial release with high reliability and easy function verification can be implement | achieved.
