OPENING PREVENTION DEVICE FOR EARTHQUAKE SENSING DOOR
PROBLEM TO BE SOLVED: To provide an entirely mechanical opening prevention device for an earthquake sensing door (an earthquake sensing door lock device) of a simple structure that does not require a power source and is with lesser restrictions for fitting, the opening prevention device for an earthquake sensing door (the earthquake sensing door lock device) also offering a lock maintaining function that may be kept locked all the time, for preventing door opening at normal times and being applicable as a child lock also.SOLUTION: An opening prevention device for an earthquake sensing door of the present invention is fitted on a door and prevents opening of the door when having sensed vibration from outside, and includes a body having a rotary engaging lever, and a lever receiver engaged with the engaging lever. An earthquake sensing part built in the body is actuated by the vibration. The actuation of the earthquake sensing part causes a latch to be disengaged, the engaging lever that is energized with regard to the body to be rotated, and an engaging part of the engaging lever to be engaged with the lever receiver.SELECTED DRAWING: Figure 1
【課題】電源を必要としない純機械式で、構造が簡単であり、取り付けの制約の少ない感震扉開放防止具(感震ドアロック装置)を提供する。また、この発明の別の目的は、常時ロック可能なロック保持機能を備えることで、通常時は扉の開放が防止されている状態を保ち、チャイルドロックとしても応用できる感震扉開放防止具(感震ドアロック装置)を提供する。【解決手段】この発明に係わる感震扉開放防止具は、扉に付着され外部からの揺れを感知して前記扉の開放を防止する感震扉開放防止具であって、回動する係合レバーを有する本体と該係合レバーと係合するレバー受けを備え、前記揺れにより本体に内蔵された感震部が作動し、前記感震部の作動によりラッチが外れ、前記本体との間で付勢されていた係合レバーが回動し、前記係合レバーの係止部が前記レバー受けに係合する。【選択図】図1
