Door lock bolt plate pivot system, and associated structures and methods

A deadbolt pivot plate assembly for mounting to a bolt housing of a deadbolt assembly, wherein the bolt housing has an exterior surface and includes a rear end and a front end opposite the rear end, and a pair of vertically-aligned pivot mounting pins located on the exterior surface of the bolt housing at the front end, the deadbolt pivot plate assembly comprising:

• a back plate having an outer surface and an inner surface opposite the outer surface, wherein the inner surface and the outer surface extend from an upper end to a lower end, the back plate including:
• a central deadbolt hole defined through the back plate from the outer surface to the inner surface, through which the rear end of the bolt housing can pass;
• an upper door fastener hole defined through the back plate from the outer surface to the inner surface, wherein the upper door fastener hole is located between the central deadbolt hole and the upper end,
• a lower door fastener hole defined through the back plate from the outer surface to the inner surface, wherein the upper door fastener hole is located between the central deadbolt hole and the lower end, and
• a plurality of assembly fastener holes defined through the back plate from the outer surface to the inner surface;
• a front plate having an outer surface and an inner surface opposite the outer surface, wherein the inner surface of the front plate and the outer surface extend from an upper end to a lower end of the front plate, the front plate including:
• a central hole defined through the front plate from the outer surface to the inner surface, through which a bolt of the deadbolt assembly can extend,
• an upper door fastener hole defined through the front plate from the outer surface to the inner surface, wherein the upper door fastener hole is located between the central hole and the upper end of the front plate,
• a lower fastener hole defined through the back plate from the outer surface to the inner surface, wherein the upper door fastener hole is located between the central hole and the lower end of the front plate, and
• a plurality of threaded fastener holes defined on the inner surface;
• a pair of plastic plate hinges pivotably located on vertically-aligned pivot mounting pins;
• and
• a plurality of assembly fasteners extending from the outer surface of the back plate, through the assembly fastener holes, and threadably attached to the plurality of threaded fastener holes on the inner surface;
• wherein the plastic plate hinges are confined between the back plate and the front plate, to define the deadbolt pivot plate assembly;
• wherein the deadbolt pivot plate assembly is affixed to the front end of the bolt housing through the hinge assembly;
• and
• wherein the deadbolt pivot plate assembly is vertically pivotable.

A deadbolt pivot plate assembly for a door jamb assembly having a bolt housing, the deadbolt pivot plate assembly comprising:

• a hinge assembly that is mountable and vertically pivotable with respect to an outer lead end of the bolt housing;
• and
• opposing plates that, when attached together, capture the hinge assembly, between the opposing plates, to define the deadbolt pivot plate assembly;
• wherein the deadbolt pivot plate assembly is affixed to the outer lead end of the bolt housing through the hinge assembly;
• and
• wherein the deadbolt pivot plate assembly is vertically pivotable.
