Patent ID: 7900490

Claim:
A method for engaging with a projection of a first component to removably secure a second component to the first component, the method comprising: positioning a rotatable member of the second component in a first rotational orientation, by rotating the rotatable member using a key adapted to rotate the rotatable member, such that the rotatable member is allowed to receive, via a gap in a perimeter of the rotatable member, the projection of the first component; positioning the rotatable member in a second rotational orientation, by rotating the rotatable member using the key adapted to rotate the rotatable member, such that the rotatable member is prevented from disengaging with the projection of the first component to secure the second component to the first component, the rotatable member being positioned in the second rotational orientation by rotating at least a portion of the rotatable member about a perimeter of the projection of the first component; and returning the rotatable member to the first rotational orientation, by rotating the rotatable member using the key adapted to rotate the rotatable member, such that the rotatable member is allowed to release, via the gap in the perimeter, the projection of the first component to remove the second component from the first component; the first component comprising one or more slots, the second component comprising one or more tabs each adapted to engage with a corresponding slot of the first component, the one or more tabs of the second component being engaged with the one or more corresponding slots of the first component when the rotatable member is positioned in the second rotational orientation to substantially prevent the second component from being pulled from the first component substantially perpendicular to a front surface of the first component.
