摘要：
An apparatus for securing a door includes a latch bolt which engages the door frame when extended and prevents the door from opening. To release the door the latch bolt is retracted by manually operated operating means, and a dogging mechanism retains the operating means in a position wherein it holds the latch bolt in its retracted position. This enables the door to be opened and closed during periods of high use without operating any of the parts of the apparatus, thus reducing wear and preventing early failure. The dogging mechanism is electrically operated and is controlled from a remote location.
摘要（中）：
一种用于固定门的装置包括一个在延伸时与门框接合并防止门打开的闩锁螺栓。 为了释放门，闩锁螺栓通过手动操作的操作装置缩回，并且卡扣机构将操作装置保持在其中将闩锁闩固定在其缩回位置的位置。 这使得门在高使用期间能够打开和关闭，而不需要操作设备的任何部件，从而减少磨损并防止早期故障。 锁定机构是电动操作的，并且由远程位置控制。
