Abstract
A sliding door lock assembly providing the feature of automatic unlatching if closed when in a latched position along with effective normal operation and burglar resistance. It employs a latch member spring biased to an open position and cammed into a closed or latched position by a lever member. If the latch is in a locked position and is impacted with the door frame upon closing, it is translated and moves the locking lever to an unlocked position. The locking lever includes a jaw portion which engages the latch effectively. The latch is generally T shaped with the head of the T within the housing of the assembly.
