System for installing corner trim with a hidden fastener
View Patent ↗A system for installing trim installations at external corners of a building includes trim and a bracket. The trim serves both an aesthetic purpose in adding a decorative feature to building envelopes and also adds an additional weatherproofing purpose in allowing for more complete weatherproofing of building envelope corners and openings. The disclosed system relates to a concealed fastening building finishing element system that enables concealed fastening of finishing trim.
1. A bracket system for securing trim to a corner of a building, the bracket system comprising:
(a) at least one bracket that is attachable to a wall, the bracket including:
(i) first and second orthogonally disposed panel elements each with an outboard end;
(ii) at least one flange extending outwardly from each of the outboard ends of the first and second orthogonally disposed panel elements; and
(iii) at least one locking tooth extending either of 1) inwardly or 2) outwardly from each of the flanges;
(b) at least one trim piece that is attachable to the bracket, the trim piece including a first outer face surface and a second outer face surface, a first hidden surface facing the building and a second hidden surface facing the building, a first cutout surface extending from the first hidden surface towards the first outer face surface, and a second cutout surface extending from the second hidden surface towards the second outer face surface, the first and second cutout surfaces defining respective sides of the trim piece;
(i) at least one longitudinally extending slot disposed within each of the first and second trim piece hidden surfaces for receiving the at least one flange extending outwardly from the outboard ends of the first and second orthogonally disposed panel elements; and
(ii) a first overhang extending from and transverse to the first cutout surface and a second overhang extending from and transverse to the second cutout surface, the first overhang and the first cutout surface defining a first cutout whereby a side edge of a siding element can be slid laterally beneath the first overhang, and the second overhang and the second cutout surface defining a second cutout whereby a side edge of another siding element can be slid laterally beneath the second overhang.
2. The bracket system of claim 1 , wherein the at least one flange extending outwardly from each of the outboard ends of the first and second orthogonally disposed panel elements is angled backwards from the plane of the first and second orthogonally disposed panel elements at an angle in the range of 120 to 150 degrees.
3. The bracket system of claim 2 , wherein the at least one flange extending outwardly from each of the outboard ends of the first and second orthogonally disposed panel elements is angled backwards from the plane of the first and second orthogonally disposed panel elements at an angle of 135 degrees.
4. The bracket system of claim 1 , wherein the first and second orthogonally disposed panel elements are joined at a longitudinally extending centerline.
5. The bracket system of claim 4 , wherein each flange extending outwardly from each of the outboard ends of the first and second orthogonally disposed panel elements has an inner face and an outer face.
6. The bracket system of claim 5 , wherein the flange inner face faces the centerline and the flange outer face faces away from the centerline.
7. The bracket system of claim 6 , wherein the at least one locking tooth extending outwardly from each of the flanges preferably extends outwardly from the outer face.
8. The bracket system of claim 6 , wherein the at least one outwardly facing locking tooth is for engagement with an interior surface of the longitudinally extending slot disposed within each of the first and second trim piece surfaces.
9. The bracket system of claim 1 , wherein at least one through hole is disposed within each of the first and second orthogonally disposed panel elements for purposes of passing a bracket securing device into the building structure.
10. The bracket system of claim 1 , wherein the at least one bracket and the at least one trim piece are fabricated from a material comprising plastic.
