Patent attributes
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 telescopically receives a curvilinear portion (21) of the track segment (15). 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). In one embodiment, a 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). In another embodiment, the track segment (14) is carried by a bracket (51), and the track segment (15) is carried by a bracket (52) with the telescopic relationship being the only connection between the track segments (14, 15).
