LATCH LOCK
PROBLEM TO BE SOLVED: To provide a latch lock capable of attenuating a sound when an inverted latch is returned and also of rapidly returning the inverted latch when a door is closed.SOLUTION: A latch lock comprises: a pressing member 8 for pressing a latch 6 out of a lock box 5 in a projection direction; a biased member 9 for biasing the pressing member 8 to the projection direction; and an invert-prevention member 65 for preventing the latch 6 from inverting by engaging the latch 6. The invert-prevention member 65 engages and detaches the latch 6 by moving in a longitudinal direction intersecting the projection direction of the latch 6, and has a drive mechanism actuated by operation of a push handle. The drive mechanism is configured to actuate the pressing member 8 and the invert-prevention member 65 so as to cooperatively move by directly or indirectly engaging the pressing member 8 and the invert-prevention member 65. A movement of the pressing member 8 in an exit-entering direction and a movement of detaching the invert-prevention member 65 from the latch 6 by the drive mechanism are cooperatively performed.SELECTED DRAWING: Figure 4
【課題】反転したラッチが復帰する際の音を消音することができると共に、扉を閉じた際に、反転したラッチを速やかに復帰させることができるラッチ錠を提供することである。【解決手段】ラッチ６を錠箱５から突出方向に押圧する押圧部材８と、押圧部材８を突出方向に付勢する付勢部材９と、ラッチ６と係合しラッチ６の反転を阻止する反転阻止部材６５を有し、反転阻止部材６５は、ラッチ６の突出方向と交差する方向に進退移動してラッチ６と係合・離脱するものであり、プッシュプルハンドルを操作することによって動作する駆動機構を有し、駆動機構は、押圧部材８及び反転阻止部材６５と直接的または間接的に係合して押圧部材８と反転阻止部材６５を連係動作させるものであり、駆動機構によって押圧部材８を退入方向へ移動させる動作と、反転阻止部材６５とラッチ６の係合を外す動作が連係して実行される。【選択図】図４
