Building trim having slidable moulding

摘要

Nail or screw holes are provided on the body of a trim unit so that the trim body can be more robustly secured to the building structure, beneath a slidable molding which in a first position reveals these holes and in a second position covers the holes. This sliding is preferably achieved by a self-retaining interference connection, such as a dovetail joint, between a movable molding part and the body of the trim unit. In a further preference, the molding has a stationary portion that is fixed with respect to the trim body, and a movable portion which, after attachment of the trim body to the structural member, can be slid into engagement with the stationary portion and glued thereon to complete the molding.

1. A building construction trim unit attached to a vertical surface of a structural member of a building, comprising:
a body having a pair of generally vertically parallel side elements and a first horizontal element extending transversely between said side elements at an upper terminal end of said body, and a decorative moulding connected to the first horizontal element; said body having an installation side vertically abutting the vertical surface of said structural member of the building and a front side opposite the installation side, with a plurality of holes passing from the front side to the installation side of the first horizontal element; wherein
the structural member is a building wall having a border around a wall penetration and the trim unit is a frame attached to the border around said penetration; andsaid connection is slidable in a direction generally vertically perpendicular to the first horizontal element and parallel with the side elements between the moulding and the first horizontal element whereby in a first position the moulding exposes the holes to receive a fastener into the structural member and in a second position the moulding covers the holes.
