    • A holdback dog for a mortise lock including a holdback dog slidably mounted to a tab on the mortise lock locking link. The holdback dog is activated by first retracting the latchbolt using the inside handle and then unlocking the lock using either the key cylinder or the inside thumbturn. When the lock is unlocked, the locking link moves downward, placing a tab on the holdback dog slide in confronting engagement with a corresponding tab on the bolt slide. After the inside handle is released, the holdback dog tab holds the bolt slide, and therefor the latchbolt, in the retracted or "dogged" position. For normal or "undogged" operation, the slidable mounting of the holdback slide allows the bolt slide tab to engage the holdback dog tab and push the holdback dog slide out of the way, when the lock is unlocked and either handle is operated, thereby permitting normal operation.
    • 一种用于榫眼的锁扣,包括可滑动地安装在榫锁锁定链节上的突出部上的扶手。 通过使用内部手柄首先缩回闩锁螺栓,然后使用钥匙筒或内部拇指转动来解锁锁,从而启动扣环。 当锁解锁时,锁定链接向下移动,将卡扣滑块上的卡扣对准螺栓滑块上的相应突舌。 在内部手柄释放后,挡板卡爪将螺栓滑块固定,并将闩锁闩住在缩回或“锁定”位置。 对于正常或“无排气”操作,保持滑块的可滑动安装允许螺栓滑动接头接合扶手卡爪,并且当锁定解锁并且手柄被操作时,将卡扣滑块推开,从而允许 普通手术。

    • Latch assemblies are disclosed including a latch bolt mounted on a casing for relative movement between an extended latching position and a retracted release position, a first actuator operable from the inner side of the assembly to cause movement of the latch bolt to the release position, a lock operable from the inner side of the assembly to adopt an active condition thus render the first actuator inoperable, a second actuator operable from an outer side of the assembly to cause movement of the latch bolt to the release position, and a lock release responsive to operation of the second actuator to render the lock inactive.
