360 degree adjustable deadbolt assembly
First Claim
1. An adjustable backset deadbolt assembly comprising:
- an outer bolt housing having a helical slot of about 360 degrees;
an inner bolt housing positioned on an interior side of the outer bolt housing and having a protrusion engageable in the helical slot of the outer bolt housing; and
a bolt configured for movement along an axis between a retracted position in which the bolt is positioned within the inner bolt housing and an extended position in which the bolt extends from the inner bolt housing,wherein the inner bolt housing and the outer bolt housing are rotatable relative to each other about the axis, guided by movement of the protrusion within the helical slot, to adjust the relative axial positioning between the outer bolt housing and the inner bolt housing and change a backset dimension between a first value and a second value.

Abstract
An adjustable backset deadbolt assembly providing operational and structural improvements. The deadbolt assembly can provide adjustability between a first backset dimension and a second backset dimension for allowing installation in doors conforming to various industry standards. The deadbolt assembly can provide adjustability between backset dimensions by relative rotation between the inner bolt housing and the outer housing. The inner bolt housing may be provided with a depressible snap finger to allow insertion of a protrusion thereon into a slot in the outer housing. In some embodiments, the slot is provided substantially helically through an angle of 360 degrees to provide common orientation of parts in each backset dimension. The outer housing may be provided to integrally form a cam housing and a bolt housing.

11. An adjustable backset deadbolt assembly comprising:
-
a bolt movable along an axis between an extended position and a retracted position; a cam operable to actuate the bolt between the extended position and the retracted position and vice versa; and a first housing rotatable relative to the bolt about the axis, a backset dimension being adjustable between a first predetermined axial value and a second predetermined axial value upon relative rotation between the first housing and the bolt, wherein the relative axial orientation between the first housing and the bolt is variable by an amount substantially equal to the difference between the first predetermined axial value and the second predetermined axial value, and wherein, after adjustment of the backset dimension, the relative rotational orientation between the first housing and the bolt is substantially identical whether the backset dimension is set to the first predetermined axial value or the second predetermined axial value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An adjustable backset deadbolt assembly having a backset dimension adjustable between a first value and a second value comprising:
-
a bolt configured for movement along an axis between a retracted position and an extended position, the bolt having a slot positioned parallel to the axis; an outer bolt housing having a helical slot of about 360 degrees, the helical slot having two ends positioned on the same side of the outer bolt housing and spaced apart along the axis; an inner bolt housing positioned on an interior side of the outer bolt housing, the inner bolt housing including a protrusion on an outer face engageable in the helical slot of the outer bolt housing, a rib on an inner face for engagement with the slot in the bolt, and an inwardly projecting dimple positioned to limit movement of the bolt; a bolt bar coupling the bolt to an input cam, the bolt being rotatable relative to the bolt bar by movement of a pin fixed to the bolt within a helical slot in the bolt bar to adjust the backset dimension; and a detent feature on the outer bolt housing providing at least one of audible and tactile feedback confirming positive positioning of the assembly into one of the first and second backset dimension values.
