Abstract

A support bracket and track assembly for the support of sectional overhead doors. The assembly comprises track means (110, 112, 114) for supporting the overhead door sections and horizontal support bracket means (80) for supporting the track means (110, 112, 114). The assembly further comprises flag bracket means (140) for mounting the track means (110, 112, 114) and support bracket means (80) to a structural support, and tab means (90, 120, 130) for attaching the track means (110, 112, 114) to the support bracket means (80) and flag bracket means (140). A related fastening system for use with overhead sectional door components comprises first (80, 140) and second (112, 114) components, tab means (90) extending from the first component (80, 140) for engaging the second component (112, 114), and tab slot means (120, 130) in the second component for receiving the tab means (90) of the first component (80, 140).

Claims

1. A support bracket and track assembly for the support of sectional overhead doors comprising:

track means for supporting the overhead door sections;

horizontal support bracket means attached to said track means for supporting said track means;

flag bracket means attached to said track means and said horizontal support bracket means for mounting said track means and said horizontal support bracket means to a structural support; and

tab means for attaching said track means to said horizontal support bracket means and said flag bracket means.

2. A support bracket and track assembly, as set forth in claim 1, wherein said track means comprises a horizontal track member and a vertical track member, said horizontal track member having a straight portion and a curved portion.

3. A support bracket and track assembly, as set forth in claim 2, wherein said flag bracket means comprises a structural mounting flange and a track supporting flange.

4. A support bracket and track assembly, as set forth in claim 3, wherein said horizontal support bracket means comprises an angle bracket having first and second ends and at least one fastener aperture in said second end.

5. A support bracket and track assembly, as set forth in claim 4, wherein said tab means comprises at least one tab member extending outwardly from said first end of said angle bracket, at least two tab members extending from said track supporting flange of said flag bracket means, at least two slotted tab apertures in said horizontal track member, and at least one tab aperture in said vertical track member.

6. A support bracket and track assembly, as set forth in claim 5, wherein each of said tab members comprises first and second arms and first and second ears extending perpendicularly from each of said first and second arms, respectively.

7. A support bracket and track assembly, as set forth in claim 6, wherein said first and second arms are joined along a common edge to form a saddle.

8. A support bracket and track assembly, as set forth in claim 7, wherein each of said slotted tab apertures comprises a first oblong portion and a second oblong portion intersecting said first oblong portion at a right angle.

9. A support bracket and track assembly, as set forth in claim 8, wherein said first oblong portion is slightly longer than the distance between said first and second ears;

and said second oblong portion is slightly wider than said first and second arms;

whereby said first and second oblong portions form a T-shaped aperture.

10. A support bracket and track assembly, as set forth in claim 9, wherein said at least one tab aperture in said vertical track member is generally circular and is interrupted by opposed semi-circles.

11. A support bracket and track assembly, as set forth in claim 10, wherein said vertical track member has a first end and a second end;

said at lease one tab aperture in said vertical track member is proximate to said first end of said vertical track member;

at least one said slotted tab aperture is located on said curved portion of said horizontal track member and at least one said slotted tab aperture is on said straight portion of said horizontal track member.

12. A support bracket and track assembly, as set forth in claim 11, wherein one of said at least two tab members on said track supporting flange of said flag bracket is angularly oriented with respect to another of said tab members on said track supporting flange.

13. A support bracket and track assembly, as set forth in claim 12, wherein said one of said at least two tab members is located directly above said another of said tab members.

14. A support bracket and track assembly, as set forth in claim 13, wherein said another of said tab members engages said tab aperture in said vertical track member;

said one of said at least two tab members engages said slotted tab aperture in said curved portion of said horizontal track member;

said at least one tab member in said angle bracket engages said at least one slotted tab aperture in said straight portion of said horizontal track member;

said angle bracket is affixed to said track supporting flange of said flag bracket.
