Patent ID: 7828501

Claim:
A mounting assembly, comprising: a base member operable to be inserted into a base opening in a wall, the base member including a flange and an arm depending from the flange, the flange including an insertion opening, the arm including a guide, the guide including a portion that is generally perpendicular to the flange and a portion that is generally non-perpendicular to the flange; and an insertion member operable to be inserted through the insertion opening in the base member, the insertion member including a generally planar surface, the insertion member further including a hub operable to interact with the guide on the arm of the base member; wherein the insertion member is moved from an insertion orientation in which the generally planar surface of the insertion member is generally perpendicular to the flange and the hub interacts with the portion of the guide that is generally perpendicular to the flange, to an intermediate orientation in which the generally planar surface of the insertion member is generally non-perpendicular to the flange and the hub interacts with the portion of the guide that is generally non-perpendicular to the flange, to an installed orientation in which the generally planar surface of the insertion member is generally parallel to the flange and the hub interacts with the portion of the guide that is generally perpendicular to the flange.
