Method for engaging with a projection of a first component to removably secure a second component to the first component

1. 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.

2. The method of claim 1 , wherein:

the first rotational orientation comprises at least one of a first range of rotational orientations; and

the second rotational orientation comprises at least one of a second range of rotational orientations.

3. The method of claim 1 , comprising engaging a ridge of the rotatable member with a channel of the projection of the first component, when the rotatable member is engaged with the projection, to help prevent the second component from being forcibly removed from the first component.

4. The method of claim 1 , wherein:

the second component comprises a plurality of castellations in a circular arrangement, a slot separating each pair of adjacent castellations; and

the rotatable member is part of a locking mechanism, the locking mechanism comprising a plurality of legs, one or more of the legs each comprising a projection adapted to extend into a corresponding slot separating adjacent castellations such that when the one or more projections of the one or more legs extend into the corresponding slots, the rotatable member cannot be rotated without breaking the one or more projections of the one or more legs.

5. The method of claim 4 , wherein positioning the rotatable member in either the first or the second rotational orientation comprises:

engaging the key with the locking mechanism; and

rotating the rotatable member of the locking mechanism using the key.

6. The method of claim 5 , wherein the key comprises:

a handle;

a hollow shaft; and

one or more projections extending from the shaft for engaging with the locking mechanism to rotate the rotatable member.

7. The method of claim 6 , wherein:

a lock plug comprises a plurality of channels each adapted to receive a corresponding leg; and

the method further comprises engaging the key with the lock plug to rotate the rotatable member.

8. The method of claim 7 , further comprising properly orienting the key such that one or more projections of the key compress corresponding legs inward to recess the corresponding projections of the legs from corresponding slots separating adjacent castellations to allow the rotatable member to be rotated using the key.

9. The method of claim 7 , wherein a housing is adapted to seat over the rotatable member to maintain:

the rotatable member in continuous contact with the lock plug;

the legs in continuous contact with the lock plug and the rotatable member; and

the lock plug in continuous contact with the second component.

10. The method of claim 6 , further comprising orienting the key such that a tab of an aperture of the second component can pass through a channel of the shaft of the key to allow the aperture to receive the key.

11. The method of claim 1 , wherein:

the rotatable member is part of a locking mechanism for use in a system integrated into a structure for injection of a material into one or more cavities in the structure;

the first component comprises a base that is coupled to the structure, the base comprising one or more ports for injecting the material into the one or more cavities in the structure; and

the second component comprises a cover.

12. The method of claim 11 , comprising:

positioning the rotatable member in the first rotational orientation such that the one or more tabs of the cover are allowed to slide upward substantially parallel to a front surface of the base to engage the one or more corresponding slots of the base to secure the cover to the base;

positioning the rotatable member in the second rotational orientation such that the one or more tabs of the cover are substantially prevented from sliding downward substantially parallel to the front surface of the base to disengage from the one or more corresponding slots of the base to secure the cover to the base; and

returning the rotatable member to the first rotational orientation such that the one or more tabs of the cover are allowed to slide downward substantially parallel to the front surface of the base to disengage from the one or more corresponding slots of the base to remove the cover from the base.

13. The method of claim 12 , wherein when the locking mechanism is engaged with the projection of the first component and the one or more tabs of the cover are engaged with the one or more corresponding slots of the base, the cover cannot be removed from the base without breaking the one or more tabs of the cover.

14. The method of claim 12 , wherein when the one or more tabs of the cover are engaged with the one or more corresponding slots of the base:

the locking mechanism being engaged with the projection of the first component substantially prevents the cover from sliding downward substantially parallel to the front surface of the base; and

the one or more tabs of the cover being engaged with the one or more corresponding slots of the base substantially prevents the cover from being pulled substantially perpendicular to the front surface of the base or from sliding upward substantially parallel to the front surface of the base.

15. The method of claim 12 , wherein:

the base comprises one or more channels each associated with a corresponding slot; and

the method further comprises:

moving the one or more tabs of the cover inward substantially perpendicular to the front surface of the base through the one or more corresponding channels of the base before sliding upward to engage the one or more corresponding slots of the base to secure the cover to the base; and

after sliding the one or more tabs of the cover downward to disengage from the one or more corresponding slots of the base, moving the one or more tabs of the cover outward substantially perpendicular to the front surface of the base through the one or more corresponding channels of the base to remove the cover from the base.
