1. A latch assembly adaptable for installation at more than one backset distance, comprising:

  • a deadbolt,a backset adjusting member including a first end engaged with the deadbolt and a second end adapted to be connected to a deadbolt operator, the first end of the backset adjusting member including a first backset position and a second backset position spaced from the first backset position along an axial direction of the backset adjusting member, each of the first backset position and the second backset position including a first angular location and a second angular location, and the backset adjusting member being rotatable relative to the deadbolt to allow each of the first backset position and the second backset position to be movable between an associated said first angular location and an associated said second angular location,a transverse positioning member movable in a direction transverse to the axial direction of the backset adjusting member between a first transverse position and a second transverse posistion in response to rotational movement of the backset adjusting member, wherein the transverse positioning member is in the first transverse position when either one of the first backset position and the second backset position is in the first angular location, and wherein the transverse psitioning member is in the second transverse position when either one of the first backset position and the second backset position is in the second angular location,a housing for receiving the deadbolt therein, the housing including an engaging means for releasably engaging with the transverse positioning member,wherein the transverse positioning member engages with the backset adjusting member and disengages from the engaging means of the housing when the transverse positioning member is in the first transverse position,wherein the transverse positioning member disengages from the backset adjusting member and engages with the engaging means of the housing when the transverse positioning member is in the second transverse position, thereby restraining relative axial movement between the deadbolt and the housing during relative axial movement between the backset adjusting member relative to the deadbolt.
