Abstract
A door lock assembly is configured for installation in a cross bore of a door. The lock assembly includes a lock housing including a disk portion having an outer perimeter and an inner wall extending from the disk portion and defining an annular space between the inner wall and the outer perimeter and a lock space inside of the inner wall. The inner wall is sized to fit within the cross bore and define an annular gap between the inner wall and the cross bore. A retention clip is removably attached to the lock housing and includes a retention portion that engages the cross bore to removably retain the lock housing within the cross bore without the use of fasteners.

A door lock assembly configured for installation in a cross bore of a door, the lock assembly comprising:
- a lock housing including
- a disk portion having an outer perimeter, the disk portion configured to be positioned outside the cross bore when attached to the door;
- and
- an inner wall extending from the disk portion and defining an annular space between the inner wall and the outer perimeter and a lock space inside of the inner wall, the inner wall sized to fit within the cross bore and define an annular gap between the inner wall and the cross bore;
- a retention clip removably attached to the lock housing and including a retention portion that is engageable with an interference fit with the cross bore to removably retain the lock housing centered within the cross bore without the use of fasteners.
A door lock assembly configured for installation in a cross bore of a door, the door having an outer surface that is perpendicular to the cross bore, the lock assembly comprising:
- a lock housing including
- a disk portion having an outer perimeter, the disk portion being configured to abut the outer surface of the door;
- and
- an inner wall extending from the disk portion and defining an annular space between the inner wall and the outer perimeter and a lock space inside of the inner wall, the inner wall sized to fit within the cross bore and define an annular gap between the inner wall and the cross bore;
- a first retention clip removably attached to the lock housing;
- and
- a second retention clip removably attached to the lock housing, the first retention clip and the second retention clip each simultaneously engaged with the lock housing and defining an interference fit with the cross bore to retain and center the lock housing within the cross bore.
A door lock assembly configured for installation in a cross bore of a door, the cross bore having a circular cross section, the lock assembly comprising:
- a lock housing including
- a disk portion having an outer perimeter;
- and
- an inner wall extending from the disk portion and defining an annular space between the inner wall and the outer perimeter and a lock space inside of the inner wall, the inner wall sized to fit within the cross bore and define an annular gap between the inner wall and the cross bore;
- a first retention clip coupled to the lock housing and completely disposed within the annular space;
- a second retention clip coupled to the lock housing and completely disposed within the annular space, the first retention clip and the second retention clip each including a biasing portion that defines an interference fit with the cross bore to position the lock housing within the cross bore without the use of fasteners.
