Patent ID: 7891400

Claim:
A track assembly for use with an overhead door, the overhead door having at least one guide member extending outwardly therefrom along a longitudinal axis, the track assembly comprising: a first track section, the first track section including: a first side portion having a first guide surface positioned at an oblique angle to the longitudinal axis of the guide member; and a second side portion having a second guide surface, wherein the second guide surface is at least approximately parallel to the longitudinal axis of the guide member, and wherein the second guide surface is spaced apart from the first guide surface to form a first V-groove configured to movably receive the overhead door guide member; and a second track section operably coupled to the first track section, the second track section including: a third side portion having a third guide surface positioned at an oblique angle to the longitudinal axis of the guide member; and a fourth side portion having a fourth guide surface positioned at an oblique angle to the longitudinal axis of the guide member, wherein the fourth guide surface is spaced apart from the third guide surface to form a second V-groove configured to movably receive the overhead door guide member; wherein the third side portion is spaced apart from the fourth side portion to define a gap region therebetween, wherein the third and fourth guide surfaces diverge from the gap region in a first direction, wherein the third side portion further includes a first retention surface positioned at an oblique angle to the longitudinal axis of the guide member, wherein the fourth side portion further includes a second retention surface positioned at an oblique angle to the longitudinal axis of the guide member, and wherein the first and second retention surfaces diverge from the gap region in a second direction, opposite to the first direction.
