Title:
【発明の名称】非常退出装置のための掛け金作動機構
Document Type and Number:
Japanese Patent JP3108081
Kind Code:
B2
Abstract:
The mechanism is configured to operate both a primary latch bolt and secondary latches, and provides for immediate, ready egress for the side of a door to which the mechanism is mounted, but offers high security for the other, outside of the door. The latch bolt is directly controlled by a first linkage, and the secondary latches are directly controlled by a second linkage. During egress, both linkages translate together, via a pin connection. However, a lost motion arrangement prevents retraction of either the bolt, or the secondary latches, if the other is compromised (or operated by a key or combination). From the outside, high security side of the door, the latch bolt and the secondary latches must be retracted together.
