摘要： A locking mechanism (1) is provided for a door latch mechanism in which a latch spindle is turnable to withdraw a latch bolt of the latch mechanism from a latching position into which it is spring biased. The locking mechanism comprises a lever handle (5) having a fluted passageway (24) for fitting to an adjacent end of the latch spindle. The passageway enables the handle to turn relatively to the latch spindle in opposite directions through a predetermined angle of movement. At one end of this angle of movement, the handle is in a horizontal rest position and is engageable with the latch spindle for turning the spindle in a direction to withdraw the latch bolt from its latching position and, at the opposite end, the handle is in a lifted locking position and is engageable with the spindle to prohibit turning thereof in the opening direction. At the locking position, a locking member (27) slidably mounted in the handle and controlled by a trigger part (30), extending behind the lever part (8) of the handle is engageable in one of a pair of retainer holes (33,34) depending on the handing of the lever handle.

摘要翻译： 本发明提供一种用于门闩机构的锁定机构（1），其中闩锁心轴可转动以将闩锁机构的闩锁闩从其被弹簧偏置的闩锁位置拉回。 锁定机构包括杠杆手柄（5），该杠杆手柄具有用于配合到闩锁心轴的相邻端部的凹槽通道（24）。 通道使得手柄能够以相反的方向相对于闩锁心轴转动预定角度的运动。 在该运动角度的一端，手柄处于水平静止位置，并且可以与闩锁心轴接合，用于在使闩锁闩从其闩锁位置退出的方向上转动心轴，并且在相反端， 处于提升的锁定位置并且可与主轴接合以禁止其沿打开方向转动。 在锁定位置处，可滑动地安装在手柄中并由触发器部件（30）控制的锁定构件（27）在手柄的杆部件（8）后面延伸，可接合在一对保持器孔（33,34） 取决于杠杆手柄的处理。
