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).

Abstract: A sectional door (20) having a plurality of panels (21, 22, 23, 24) including, a body portion (25) of the panels spacing and joining longitudinal edges (40, 50), one of the edges (40) between adjacent panels on a first panel having a substantially concave curvilinear surface (45) in vertical cross-section, the other of the edges (50) between adjacent panels on a second panel having a substantially planar surface (52) in vertical cross-section, longitudinally-spaced hinges (65) interconnecting the first and second panels for pivotal movement.

Abstract: A jamb bracket (10, 40) and track (30, 60) assembly for the support of overhead sectional doors and the like. The assembly comprises bracket means (10,40) having tab means (20,50) and track means (30,60) having tab slots (34,74). The tab means (20,40) engage the tab slots (34,74) for attachment of the bracket means (10,40) to the track means (30,60). A related jamb bracket (10,40) comprises a U-shaped main body (14,44), providing first and second perpendicularly disposed legs (16,46 and 18,48) and, tab means (30,60) offset from the main body (14,44).
