Abstract

Overhead door assemblies having both interlocking and releasable guide assemblies, and multi-piece guide track assemblies for use with same are disclosed herein. An overhead door track configured in accordance with one embodiment of the invention includes a first side portion formed from a first piece of material and a second side portion formed from a second piece of material. The first side portion has a first guide surface and a first retention surface. The second side portion has a second guide surface and a second retention surface. In one aspect of this embodiment, the first side portion is joined to the second side portion to define an open channel or gap region therebetween. The first and second guide surfaces extend from the gap region toward a first direction, and the first and second retention surfaces diverge from the gap region toward a second direction, opposite to the first direction. The first and second retention surfaces can be configured to movably retain a door guide member.

a second side portion formed from a second piece of material, the 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, the 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, the 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.

11. The track assembly of claim 10 wherein the first side portion and the third side portion are formed from the same first piece of material.

12. The track assembly of claim 10 wherein the first side portion and the third side portion are formed from the same first piece of material, and wherein the fourth side portion is formed from a third piece of material.

13. The track assembly of claim 10 wherein the first side portion further includes a first flange, wherein the second side portion further includes a second flange that overlaps a first portion of the first flange, and wherein the fourth side portion further includes a third flange that overlaps a second portion of the first flange.

14. The track assembly of claim 13, further comprising a first plurality of fasteners extending though the overlapping portions of the first and second flanges, and a second plurality of fasteners extending through the overlapping portions of the first and fourth flanges.
