Segmented wind lock configuration for overhead roll-up doors and method of constructing the same
View Patent ↗An overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening, the door assembly having a door panel with two faces and opposing marginal and lateral edges, and at least two wind locks attached proximate each marginal edge. The at least two wind locks extend away from one face of the door panel in a direction substantially perpendicular thereto, and are spaced apart vertically along each respective side edge of the door panel. The assembly further includes a drum for winding and unwinding the door panel to permit and prohibit access to the opening, and, a pair of opposing parallel side columns aligned and spaced apart such that each of the opposing side edges engage one of the side columns in a manner in which at least a portion of the side columns guide vertical movement of the door panel.
1. An overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening, the door assembly comprising:
a door panel having two faces and opposing marginal and lateral edges, the door panel having at least two wind locks attached proximate each marginal edge wherein each of the at least two wind locks attached proximate each marginal edge
extend away from one face of the door panel in a direction substantially perpendicular thereto,
are spaced apart vertically from each other proximate each respective marginal edge of the door panel, and
are constructed using materials having at least two different durometers
a drum for winding and unwinding the door panel to permit and prohibit access to the opening; and,
a pair of opposing substantially parallel side columns aligned and spaced apart such that at least a portion of each of the opposing marginal edges engage one of the opposing substantially parallel side columns in a manner in which at least a portion of each of the opposing substantially parallel side columns guide vertical travel of the door panel as the door opens and closes, wherein each of the at least two wind locks positioned proximate each respective marginal edge of the door panel is configured so that a portion having a higher durometer of the at least two different durometers of each of the at least two wind locks engages a portion of the opposing substantially parallel side columns when a wind load is applied to the door panel.
2. The door assembly of claim 1 wherein each of the least two wind locks attached proximate each marginal edge includes:
a compressible material; and,
an angled portion facing the interior of the opening configured to engage a portion of the side column.
3. The door assembly of claim 1 further comprising a strip of material attached proximate each marginal edge on an opposite face of the door panel of that of the wind locks.
4. The door assembly of claim 3 wherein the strip of material attached proximate each marginal edge on the opposite face is substantially continuous from a top edge of the door panel to a bottom edge of the door panel.
5. The door assembly of claim 1 wherein at least three wind locks are attached proximate each of the opposing marginal edges of the door panel.
6. The door assembly of claim 1 wherein at least four wind locks are attached proximate each of the opposing marginal edges of the door panel.
7. The door assembly of claim 1 wherein each of the wind locks includes an angled portion for engaging a portion of the side columns, the angled portion being made of the higher durometer material.
8. The door assembly of claim 7 wherein the angled portion includes a planar face.
9. The door assembly of claim 8 wherein the angled portion includes at least two ribs.
10. The door assembly of claim 1 wherein the at least two wind locks attached proximate each of the opposing marginal edges are a co-extrusion of materials having different durometers.
