したがって、第１、第２クランプ体８，２１は、レバーハンドル５の起伏回転に連動して、非ロック位置（図１）とロック位置（図３）との間を正逆回転し、ロック位置においてフック部１０，２３が、それぞれ第１、第２ストライク１，２に対して上方又は下方から背面に係合し、非ロック位置においてフック部１０，２３が第１、第２ストライク１，２から離脱する。 Accordingly, the first and second clamp bodies 8 and 21 rotate forward and backward between the unlocked position (FIG. 1) and the locked position (FIG. 3) in conjunction with the up-and-down rotation of the lever handle 5. The hook portions 10 and 23 engage with the first and second strikes 1 and 2 from the upper side or the lower side, respectively, and the hook portions 10 and 23 are engaged with the first and second strikes 1 and 2 in the unlocked position. Leave.

反転ばね１９は、実質的に、一端側が第１可動枢軸１３に係止され、他端側が第２固定枢軸７に係止されているので、非ロック位置にあるレバーハンドル５を起立状態（図１）に保持（図１において固定枢軸４を中心に反時計方向の回転力を付与）し、非ロック位置からロック位置への回転途上（図２）で圧死点を越え、ロック位置（図３）にあるレバーハンドル５を倒伏状態に保持（図３において軸４を中心に時計方向の回転力を付与）する。 The reversing spring 19 is substantially engaged at one end side with the first movable pivot 13 and at the other end with the second fixed pivot 7, so that the lever handle 5 in the unlocked position is raised (see FIG. 1) (applying a counterclockwise rotational force about the fixed pivot 4 in FIG. 1), the pressure dead center is exceeded during the rotation from the unlocked position to the locked position (FIG. 2), and the locked position (FIG. 3). ) Is held in a lying state (a clockwise rotational force is applied about the shaft 4 in FIG. 3).

しかして、ロックハンドル装置の本体は、図１に示すように、クランプ体８，２１のフック部１０，２３がストライク１，２から離脱した非ロック位置において、第１可動枢軸（第１枢支点）１３と第２可動枢軸（第２枢支点）１６とを結ぶ直線Ｌ１が、第２可動枢軸（第２枢支点）１６から扉前面に対して直角に延びる基準直線Ｌより下方にある一方、図３に示すように、クランプ体８，２１のフック部１０，２３がストライク１，２に係合したロック位置において、直線Ｌ１が、基準直線Ｌを上方へ越えた位置に来るように各部が配置される。 Thus, as shown in FIG. 1, the main body of the lock handle device has a first movable pivot (first pivot point) at the unlocked position where the hooks 10, 23 of the clamp bodies 8, 21 are disengaged from the strikes 1, 2. ) While a straight line L1 connecting 13 and the second movable pivot (second pivot point) 16 is below a reference straight line L extending perpendicularly from the second movable pivot (second pivot point) 16 to the door front surface, As shown in FIG. 3, in the locked position where the hook portions 10 and 23 of the clamp bodies 8 and 21 are engaged with the strikes 1 and 2, the respective portions are arranged so that the straight line L <b> 1 comes to a position beyond the reference straight line L. Be placed.

今、図１に示す非ロック状態において、レバーハンドル５は、ハンドルベース３から起立し、反転ばね１９により、起立状態に保持されている。第１、第２クランプ体８，２１のフック部１０，２３は、それぞれ第１、第２ストライク１，２から離脱している。直線Ｌ１は、基準直線Ｌの右下側にある。 Now, in the unlocked state shown in FIG. 1, the lever handle 5 stands from the handle base 3 and is held in the standing state by the reversing spring 19. The hook portions 10 and 23 of the first and second clamp bodies 8 and 21 are detached from the first and second strikes 1 and 2, respectively. The straight line L1 is on the lower right side of the reference straight line L.

この状態から、反転ばね１９に抗してレバーハンドル５を倒伏方向(時計方向)へ回転させると、図２に示す中間位置において反転ばね１９が圧死点に達し、これを越えると、レバーハンドル５は倒伏方向へ付勢され、図３に示すロック位置に至る。この間に、直線Ｌ１は、基準直線Ｌを上方へ越えて右上側に配置される。この状態では、外部の衝撃や振動、扉の自重、固定枠体の内部圧力等によりフック部１０，２３が離脱方向（フック部１０が図において時計方向、フック部２３が図において反時計方向）への回転力を受けても、連結リンク１４が回転できないので、フック部１０，２３がストライク１，２から離脱することはない。扉は２点でロックされるので良好な密閉状態が確保される。 From this state, when the lever handle 5 is rotated counterclockwise (clockwise) against the reversing spring 19, the reversing spring 19 reaches the pressure dead center at the intermediate position shown in FIG. Is biased in the lying down direction to reach the locked position shown in FIG. During this time, the straight line L1 is disposed on the upper right side, exceeding the reference straight line L upward. In this state, the hooks 10 and 23 are disengaged due to external impact and vibration, the weight of the door, the internal pressure of the fixed frame, etc. (the hook 10 is clockwise in the figure and the hook 23 is counterclockwise in the figure). Even if the connecting link 14 is not rotated even if it receives a rotational force, the hook portions 10 and 23 do not leave the strikes 1 and 2. Since the door is locked at two points, a good sealed state is secured.
