Bracket system for attaching a cantilevered pergola to a roof rafter
View Patent ↗A bracket system, for suspending pergola beams from an existing structure, the existing structure having a vertical wall and roof rafters that each have a rafter top and a rafter end that extends beyond the vertical wall over a ground surface, each of the pergola beams having a supported end, including a plurality of brackets. Each bracket having a mounting assembly for attaching to one of the rafters, a support assembly for attaching the support end of one of the pergola beams, and a connecting assembly that suspends the support assembly from the mounting assembly. The pergola beams extend over the ground surface, away from the existing structure, supported only by the bracket at the support end and without any vertical supports.
1 . A bracket, for suspending a pergola beam from an existing structure, the existing structure having a vertical wall and horizontal rafters that each have a rafter top, a rafter bottom, and a rafter end that extends beyond the vertical wall over a ground surface, each of the pergola beams having a supported end, the bracket comprising:
A rectangular plate having a top edge, bottom edge, front edge, and rear edge, that is cut along a cut line including a first cut line that is parallel to the top edge of the rectangular plate and a second cut line that extends from the first cut line, parallel to the front edge of the rectangular plate, the rectangular plate has a main region, and a secondary region that is defined by the rear edge of the rectangular plate, the first cut line and second cut line, by a first fold line that extends parallel to the first cut line, and a second fold line that extends parallel to the first cut line, the rectangular plate is bent to form:
a support assembly having a top plate, a first open end, a second open end, and a pair of side plates, the pair of side plates and first open end the support assembly adapted for supporting one of the pergola beams with said pergola beam extending fully between the side plates and between the first open end and the second open end, wherein the support assembly is formed by the secondary region that is separated from the main region along the cut line, orthogonally folded along the first fold line to form the top plate, and then orthogonally folded along the second fold line to form one of the side plates;
a mounting assembly, including a mounting plate, the mounting plate having a top edge, a front edge, an inside surface and an outside surface, the inside surface facing in the direction of the support assembly, the mounting assembly adapted to secure to one of the roof rafters with the roof rafter extending against the inside surface and the rafter top extending parallel to the top edge of the mounting plate; and
a connecting assembly connecting and extending between the support assembly and the mounting assembly, the connecting assembly coplanar with the mounting plate and with one of the side plates of the support assembly.
2 . The bracket as recited in claim 1 , wherein the mounting plate is part of the main region, extending between the first cut line and top edge of the rectangular plate; wherein one of the side plates of the support assembly is part of the main region extending between the first fold line and the bottom edge of the rectangular plate; and wherein the connecting assembly is the main region extending between the mounting plate and support assembly.
3 . The bracket as recited in claim 2 , further comprising a vertical brace, the vertical brace extending along the front edge of the rectangular plate, alongside the mounting assembly, support assembly, and connecting assembly.
4 . The bracket as recited in claim 3 , wherein the rectangular plate has a third fold line extending near and parallel to the front edge of the rectangular plate that defines a tertiary region; and wherein the vertical brace is formed by orthogonally folding the tertiary region in a vertical plane in a direction away from the support tube.
5 . The bracket as recited in claim 4 , wherein the bracket is constructed in a single piece from the rectangular plate.
6 . The bracket as recited in claim 5 , wherein the mounting plate has mounting holes that extend fully between the inside surface and the outside surface, and further comprise mounting fasteners adapted for extending through the mounting holes and into one of the rafters.
7 . The bracket as recited in claim 6 , wherein the support assembly has support holes extending through the side plates; and further comprising support fasteners adapted for extending through the support holes and into the pergola beams.
