LATCH LOCK
PROBLEM TO BE SOLVED: To provide a latch lock which makes moving speed reduce at the time of returning of a latch with a simple composition, and is difficult to cause sound at the time of opening and closing of a door.SOLUTION: A latch lock has a latch unit 4 which is installed to a lock box. The latch unit 4 has a latch 6 and a latch case 7. The latch 6 can move and slide between a protrusion position and a recess position, and, in the latch case 7, a spring 9 and a push member 8 which pushes the latch 6 as being pushed in the protrusion direction of the latch 6 by the spring 9 are provided. Further, the latch unit 4 has a moving speed inhibition mechanism 55. The moving speed inhibition mechanism 55 has a pinion 38 and a rotary dumper 33 which inhibits rotation speed of the pinion 38, and a straight rack tooth row 41a. The pinion 38 is provided to the push member 8. The rack tooth row 41a is provided to the latch case 7. The pinion 38 is engaged with the rack tooth row 41a and can move relatively along the rack tooth row 41a.SELECTED DRAWING: Figure 11
【課題】簡単な構成でラッチの復帰時の移動速度を低減させ、扉の開閉時に音が生じにくいラッチ錠を提供することである。【解決手段】錠箱に装着されるラッチユニット４を有し、ラッチユニット４は、ラッチ６とラッチケース７を有し、ラッチ６は、突出位置と退入位置の間をスライド移動可能であり、ラッチケース７内には、ばね９と、ばね９によってラッチ６の突出方向に付勢されてラッチ６を押圧する押圧部材８が設けてある。また、ラッチユニット４は、移動速度抑制機構５５を有し、移動速度抑制機構５５は、ピニオン３８と、ピニオン３８の回転速度を抑制するロータリダンパ３３と、直線状のラック歯列４１ａを有し、押圧部材８にピニオン３８が設けられており、ラッチケース７にラック歯列４１ａが設けられており、ピニオン３８がラック歯列４１ａと係合しラック歯列４１ａに沿って相対移動可能である。【選択図】図１１
