Adjustable dead-latching bolt mechanisms

An apparatus, comprising:

• a displacement rod structured for displacement between a retracted rod position and an extended rod position;
• a first link pivotally coupled to the displacement rod;
• a second link pivotally coupled to the first link;
• and
• a latch bolt configured for displacement between an extended position and a retracted position, the latch bolt having a first elongate latch slot, a second elongate latch slot, a latch pin extending into and displaceable along a length of the first elongate latch slot during displacement of the latch bolt, and a static latch pin extending into and displaceable along a length of the second elongate latch slot during displacement of the latch bolt.

An apparatus, comprising:

• a displacement rod structured for displacement between a retracted rod position and an extended rod position;
• at least one first link having a first end and an elongate link slot, the first end of the at least one first link pivotally coupled to the displacement rod by a first link pin;
• at least one second link having a first end and a second end, the first end of the at least one second link pivotally coupled to the at least one first link by a second link pin extending into and displaceable along a length of the elongate link slot during displacement of the displacement rod;
• and
• a latch bolt pivotally coupled to the second end of the at least one second link by a latch pin, the latch bolt structured for displacement between an extended position and a retracted position, wherein the latch bolt has an elongate latch slot with the latch pin extending into and displaceable along a length of the elongate latch slot during displacement of the latch bolt between the extended and retracted positons.
