    • A push-pull door latch mechanism for latching/unlatching a retractable latch bolt of a latch bolt assembly. The latch mechanism includes a pair of handles, one on either side of a door, each handle having an engagement portion configured to engage a pin on a corresponding first and second rotatable cam. Each cam is provided with a latch bolt assembly engaging portion operably connected to the latch bolt assembly. The first cam further has a locking shoulder configured for selective engagement with a first lock member. A lock coupling operably connects the first lock member with a second lock member such that rotational movement of one of the first and second lock members causes rotational movement of the other of the first and second lock members. A lock knob provided on the interior side of the door is operably connected to the first lock member and facilitates toggling of the first and second lock members between the locked and unlocked positions. An override knob provided on the exterior side of the door is operably connected to the second lock member and facilitates toggling of the first and second lock members between the locked and unlocked positions.
    • 一种用于闩锁/解锁闩锁螺栓组件的可伸缩闩锁的推拉门闩锁机构。 闩锁机构包括一对手柄,一个在门的任一侧,每个手柄具有接合部分,该接合部分构造成与相应的第一和第二可旋转凸轮上的销接合。 每个凸轮设置有可操作地连接到闩锁螺栓组件的闩锁螺栓组件接合部分。 第一凸轮还具有锁定肩部,该锁定肩构造成与第一锁定构件选择性地接合。 锁定联接器可操作地将第一锁定构件与第二锁定构件连接,使得第一和第二锁定构件之一的旋转运动导致第一和第二锁定构件中的另一个的旋转运动。 设置在门的内侧的锁定旋钮可操作地连接到第一锁定构件,并且便于在锁定位置和解锁位置之间切换第一和第二锁定构件。 设置在门的外侧上的超控旋钮可操作地连接到第二锁定构件,并且有助于在锁定位置和解锁位置之间切换第一和第二锁定构件。
