Apparatus for Trimming Interior Walls

Apparatus for trimming interior walls of a building comprising:

• a plurality of fenestration jamb members including a first and a second jamb member arranged at right angles for surrounding a fenestration opening;
• each of the jamb members providing an front face located at an edge of one of the interior walls;
• a plurality of elongate facing boards;
• each facing board having a front face defining an attractive edge face and a rear face for fastening to the wall;
• each of the first and second jamb members having associated therewith a respective first and second of the elongate facing boards mounted on a respective one of the interior walls along the edge of the wall for forming the attractive edge face of the wall;
• each facing board having an inner edge facing inwardly along the wall and an outer edge located at the front face of the jamb member;
• each facing board having in said front face of the board at a position spaced from the front face of the jamb member a continuously longitudinally extending groove;
• the groove having a base recessed from the front face;
• the groove having a first side edge in said front face at a position spaced from said inner edge of the board and a second side edge on said front face at a position spaced from the outer edge of the board;
• the rear face of the board being fastened to the wall by a series of screws at spaced positions along the base of the groove of the board with the screws being recessed in the groove from the front face of the board;
• and an extruded plastic strip inserted into the groove along the length of the board and covering the groove and the screws therein;
• wherein the extruded plastic strip has a cap portion outside the groove and an insert portion extending into the groove;
• the groove having a first a first side wall extending from the base to the first side edge and a second side wall extending from the base to the second side edge;
• the first and second side walls being shaped to cooperate with a respective side edge of the insert portion of the extruded plastic strip to restrain the insert portion against movement out of the groove;
• the cap portion having first and second side edges and an outer surface therebetween;
• the first side edge of the cap portion being located on the front face of the board at a position spaced from the first side edge of the groove toward but spaced from said inner edge of the board;
• the second side edge of the cap portion being located on the front face of the board at a position spaced from the second side edge of the groove toward but spaced from said outer edge of the board;
• and a connection element, which is separate and spaced from the screws, connecting the board to the respective jamb member, the connection element including a component on the rear face of the board and a component on the jamb member.
