Abstract: A two stage door lock for mobile units and similar habitable structures makes use of a relatively thin lock structure secured to the inside face of the door cooperating with a strike pin mounted on a bracket on the exterior of the door frame. Oppositely pivoted latching elements have complementary recessed jaws spring urged toward closed position and adapted to be latched around one or the other of two annular recesses in the strike pin in either a partially closed position or full closed position. A transversely extending rectangular hole slidably accommodates a locking latch bolt, fingers of which slide into recesses at the jaw end of the latching elements to lock them in engagement with the strike pin when the door is in full closed position. When the latch bolt is slid away to unlocked position, a rectangular spindle is rotated by action of a handle to spread the jaws away from engagement with the strike pin. When the jaws do not engage the latch bolt in closed position they cannot be locked by the latch bolt because a shoulder in a rectangular hole prevents the latch bolt from sliding to locked position.

Abstract translation: 用于移动单元和类似的可居住结构的两级门锁使用固定到门的内表面的相对薄的锁定结构，其与安装在门框外部的支架上的敲击销协作。 相对枢转的闭锁元件具有互补的凹入的爪，弹簧被推向关闭位置，并且适于在打开销中的两个环形凹部中的一个或另一个处锁定在部分关闭位置或完全关闭位置。 横向延伸的矩形孔可滑动地容纳锁定的闩锁螺栓，其指状物在门处于完全关闭位置时滑动到闩锁元件的钳口端部处的凹槽中，以锁定它们与撞击销接合。 当闩锁螺栓滑动到解锁位置时，通过手柄的作用使矩形主轴旋转，以使夹钳远离与撞针接合。 当卡爪不在闭合位置接合闩锁时，它们不能被闩锁锁定，因为矩形孔中的肩部防止闩锁闩锁滑动到锁定位置。
