ADJUSTABLE DEAD-LATCHING BOLT MECHANISMS

摘要

Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

主权项

1. An apparatus, comprising:
a displacement rod having a rod protrusion and an aperture, the displacement rod adapted for displacement between a first rod position and a second rod position; a lever member pivotally coupled to the displacement rod, the lever member having an abutment member and a foot portion, the abutment member extending from the lever member toward the displacement rod, the rod protrusion structured to engage the abutment member to pivotally displace the lever member from a first position to a second position as the displacement rod is displaced from the first rod position to the second rod position; and a latch bolt having a bolt protrusion, at least a portion of the latch bolt structured for slideable insertion into the aperture, the foot portion structured to impede displacement of at least the bolt protrusion from an extended position to a retracted position when the lever member is in the first position.
