Lock assembly and method of installing the same

An electronic lock housing assembly for a door comprising:

• a mounting plate including a substantially cylindrical bore projection, the substantially cylindrical bore projection configured to be received at least partially within a bore within the door such that the mounting plate is positionable against a surface of the door;
• an outer housing body coupled to the mounting plate and configured to support one or more systems configured to actuate a latch assembly, the outer housing body including at least one support arm;
• and
• one or more elastomeric retainers positioned along an outer perimeter of the substantially cylindrical bore projection, distal ends of the one or more elastomeric retainers projecting further out from the mounting plate than the substantially cylindrical bore projection, wherein at least one of the one or more elastomeric retainers has the distal end defining an opening that at least partially receives the at least one support arm, and wherein the one or more elastomeric retainers are configured to be received at least partially within the bore and engage with a sidewall of the bore so as to retain the housing assembly on the door.

A lock assembly for a door comprising:

• a latch assembly having a bolt movable between at least an extended position and a retracted position;
• a torque blade coupled to the latch assembly and selectively rotatable around a shaft axis for moving the bolt between the extended position and the retracted position;
• and
• an exterior housing assembly configured to couple to the torque blade for driving rotation thereof, the exterior housing assembly including:
• a housing including one or more bore projections and one or more support arms extending along the shaft axis, the one or more bore projections and the one or more support arms configured to be received at least partially within a bore within the door such that the housing is positionable against a surface of the door;
• one or more elastomeric retainers coupled to the housing and extending adjacent the one or more bore projections, wherein the one or more elastomeric retainers are configured to be received at least partially within the bore and engage with a sidewall of the bore so as to retain the exterior housing assembly on the door, and wherein at least one of the one or more elastomeric retainers has a distal end defining an opening that at least partially receives the one or more support arms;
• and
• at least a portion of an electronic actuation system for the latch assembly and configured to drive rotation of the torque blade.

A method of installing a lock assembly on a door, the method comprising:

• providing a housing assembly including a mounting plate having a substantially cylindrical bore projection and one or more support arms, one or more elastomeric retainers positioned along an outer perimeter of the substantially cylindrical bore projection, and a wiring harness, distal ends of the one or more elastomeric retainers projecting further out from the mounting plate than the substantially cylindrical bore projection, and wherein at least one of the one or more elastomeric retainers has the distal end defining an opening that at least partially receives the one or more support arms;
• inserting the substantially cylindrical bore projection and the one or more support arms with the one or more elastomeric retainers within a bore of the door such that the mounting plate is positioned against a surface of the door, wherein the one or more elastomeric retainers engage with a sidewall of the bore so as to retain the housing assembly on the door;
• and
• upon retention of the housing assembly within the bore of the door, sealing the wiring harness at the housing assembly with the one or more elastomeric retainers.
