摘要： A dogging device for securing a panic exit and actuation device in an unlatched condition. The dogging device uses a U-shaped spring clip to secure a base plate, a dogging adapter and a dogging hook together. The base plate, dogging adapter and dogging hook are rotated about a common axis by an operator, which can either be a hex shaft or a cylinder adapter operated by a keyed lock, from a disengaged position to an engaged position where the dogging hook engages a control rod of the exit device thereby holding, or dogging, the exit device in an unlatched condition. An over center spring is used to bias the dogging hook into either the engaged or the disengaged position.

摘要： A mechanism for dogging a door latch assembly of a panic exit device having a retractible door latch biased to move outward from the door latch assembly, with inward movement of the door latch being activated by a push bar, includes a mechanism for holding a key cylinder positioned adjacent to the door latch assembly. A catch mechanism linked to the door latch is configured to move as the door latch is retracted, and a arm is pivotably mounted adjacent to the key cylinder holding mechanism. The arm is configured to retain the catch mechanism, with the door latch being prevented from outwardly moving with respect to the door latch assembly. When a key cylinder having an attached sweep arm is rotated, the sweep arm can alternatively rotate to engage the catch mechanism when a key is turned in the key cylinder, dogging the door latch assembly, or undog the catch mechanism from the arm by sweeping around to break the attachment between the arm and catch mechanism, allowing the door latch to move from its retracted position to its normally biased outward position with respect to the door latch assembly.
摘要翻译：一种用于锁定紧急出口装置的门闩组件的机构，具有可伸缩的门闩锁，其被偏置以从门闩组件向外移动，门闩由活动杆推动的向内运动包括用于保持钥匙筒的机构定位在门闩组件附近。与门闩连接的止动机构被构造成随着门闩被缩回而移动，并且臂可相对于钥匙筒保持机构可枢转地安装。臂被构造成保持锁定机构，其中门闩被阻止相对于门闩组件向外移动。当具有附接的扫掠臂的钥匙筒旋转时，当钥匙在钥匙筒中转动时，扫把臂可以旋转以接合卡扣机构，锁住门闩组件，或者通过扫掠围绕锁定机构脱离手臂以破坏臂和捕获机构之间的附接，允许门闩相对于门闩组件从其缩回位置移动到其正常偏置的向外位置。
