Track assembly for an overhead door
First Claim
1. A track assembly for an overhead door comprising a generally vertically positionable first track segment including a generally straight portion and a curvilinear portion having a first radius of curvature, a generally horizontally positionable second track segment including a generally straight portion and a curvilinear portion having a second radius of curvature, said second radius of curvature being larger than said first radius of curvature, and means to attach said curvilinear portion of said first track segment to said curvilinear portion of said second track segment.

Abstract
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).

- 1. A track assembly for an overhead door comprising a generally vertically positionable first track segment including a generally straight portion and a curvilinear portion having a first radius of curvature, a generally horizontally positionable second track segment including a generally straight portion and a curvilinear portion having a second radius of curvature, said second radius of curvature being larger than said first radius of curvature, and means to attach said curvilinear portion of said first track segment to said curvilinear portion of said second track segment.
- 16. A track assembly for the rollers of an overhead door comprising a first track segment having a generally straight portion and a curvilinear portion having a first radius of curvature, and a second track segment having a generally straight portion and a curvilinear portion having a second radius of curvature, said curvilinear portions of said track segments being attached to each other in such a way so as to form a continuous track for the rollers, the ratio of said second radius of curvature to said first radius of curvature being in the range of approximately twenty-to-one to approximately six-to-one.
- 20. A track assembly for an overhead door comprising a first track segment having a generally straight portion and a curvilinear portion having a first radius of curvature, a second track segment having a generally straight portion and a curvilinear portion having a second radius of curvature, and a bracket being attachable to said curvilinear portion of said first track segment and being attachable to said curvilinear portion of said second track segment so as to attach said first and second track segments to each other.
