摘要

A track assembly for an overhead door (10) includes a generally vertically positionable track segment (14) and a generally horizontally positionable track segment (15). The track segment (14) includes a curvilinear portion (17) at one end thereof which is joined to a curvilinear portion (21) of the track segment (15) by a bracket (30). The curvilinear portion (17) of the track segment (14) has a smaller radius of curvature than the curvilinear portion (21) of the track segment (15). The bracket (30) has tabs (40) which are received in a slot aperture (42) in the curvilinear portion (17) to attach it to the bracket (30), and the bracket (30) has a lug (41) which is received in a slot (44) in the curvilinear portion (21) to attach it to the bracket (30).
