Patent ID: 8495844

Claim:
In a construction comprising a dynamically varying gap between a wall finish and a ceiling moving relative thereto, wherein a deflection component provides a slip joint coupling between the ceiling and a vertical framing component, and wherein the wall finish is attached to a surface of the vertical framing component, the improvement comprising a retainer clip for holding a trim strip over the dynamically varying gap, the retainer clip comprising an L-shaped member comprising a vertical back portion and a horizontal projecting tongue formed of one piece of a resilient material, wherein the vertical back portion is fixedly anchored to a vertical side of the deflection component and wherein the horizontal projecting tongue comprises a first interlocking portion at a top near the ceiling formed to lock with a corresponding second interlocking portion of the trim strip so that the trim strip is pressed tight against a surface of the wall finish and a resiliency of the resilient material of the horizontal projecting tongue presses the trim strip tight against a surface of the ceiling to conceal the dynamically varying gap.
