Abstract:
1. An apparatus adapted to fit in a recessed opening comprising: a base having a first side and a second side; a rotatable plate positioned on the first side of the base and having a first side with a spiral-shaped ridge defining a continuous channel between inwardly spiraling portions of the ridge; and at least one extendable member having a first end and a second end, and positioned relative to the spiral-shaped ridge wherein at least one protrusion on a first side of the at least one extendable member engages the channel; and a housing having an open interior space within which the rotatable plate and the at least one extendable member are positioned, comprising: wherein as the plate is rotated in a first direction, the protrusion slides within the channel forcing the extendable member to move radially outward from a center of the plate while the interior surface of the solid cover maintains contact with the second side of the extendable member and extending through the gap in the side of the housing, and as the plate is rotated in a second direction, the protrusion slides within the channel forcing the extendable member to move radially inward from the center of the plate and retracting through the gap in the side of the housing while the interior surface of the solid cover maintains contact with the second side of the extendable member; and wherein upon the extendable member moving radially outward and passing through the gap in the side of the housing, the first end of the extendable member contacts an interior surface of the recessed opening maintaining the apparatus in position within the recessed opening.
