Self-adjusting trim assembly at flexible ceiling and stationary wall junction

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 comprising an L-shaped member comprising a vertical back portion and a resilient horizontal projecting tongue formed of one piece of resilient material, and wherein the vertical back portion is fixedly anchored to a vertical side of the deflection component;
• and
• a trim strip for interlocking with the retainer clip to hold the trim strip over and conceal the dynamically varying gap, the trim strip comprising an elongated member formed of a resilient material with an L-shape in cross section and comprising a horizontal top portion and a face portion, wherein the horizontal top portion has an interlocking portion to lock with corresponding interlocking portions of the resilient horizontal projecting tongues of a plurality of the retainer clips so that the resilient horizontal projecting tongues of the retainer clips press the horizontal top portion of the trim strip tight against a surface of the ceiling and a resiliency of the resilient material of the trim strip presses a bottom of the face portion of the trim strip tight against a surface of the wall finish to conceal the dynamically varying gap.

A method of installing a trim strip over 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 method comprising the steps of:

• (a) obtaining a 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;
• (b) securing the retainer clip 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;
• and
• (c) obtaining and installing the trim strip comprising a second interlocking portion to couple and lock with corresponding of the first interlocking portion so that the trim strip is anchored over the dynamically varying gap with respective longitudinal sides of the trim strip pressed tight against the wall finish and a resiliency of the resilient material of the horizontal projecting tongue presses the trim strip tight against the ceiling to conceal the dynamically varying gap.
