Abstract

Disclosed is a sectional door adapted to withstand high wind load and impact from flying debris. The door includes a glazing bead to secure glazing panels into frames formed by the rails and stiles of the door. The bead is connected with the frame by engagement between extensions on the bead and respective lips along the edges of the frame. The bead is pressed against the frame, causing the extension to elastically flex to allow the extensions to fit between the lips. The extensions are received in gaps formed by the lips to secure the bead in place on the frame. Force on the door cause by high winds is communicated from the glazing panel through the bead and to the frame. The door also includes reinforcements arranged along the rails to communicate forces, such as high wind load forces, from the frame to the edges of the doorway surrounding the door. The reinforcements include endcaps that increase stiffness of the rails to prevent the rails from buckling during severe weather events.

First claim

We claim:

1. A reinforced door, comprising:
a rail extending across a width of the door;
a reinforcement member arranged parallel with the rail, wherein the reinforcement member extends along the rail at least partially across the width of the door, and wherein the reinforcement member comprises:
a body, wherein the body defines a plane with a first edge and second edge;
a root extending from the body, wherein the root connects the body with the rail, wherein the root extends in a longitudinal direction along the first edge; and
one or more end flanges extending in the longitudinal direction along or proximate to the second edge of the body, wherein the second edge is opposite the first edge, and
wherein the root and the one or more end flanges extend perpendicular to the plane;
an endcap connected with the second edge of the reinforcement member and arranged parallel with the reinforcement member, wherein the endcap comprises a plurality of gaps along a first edge of the endcap, wherein the end flanges of the reinforcement member are received into the gaps to connect the endcap with the reinforcement member.

2. The reinforced door of claim 1 , wherein the body defines a plane along the longitudinal direction and wherein the root and the one or more end flanges extend perpendicular to the plane.

3. The reinforced door of claim 1 , further comprising one or more intermediate flanges extending perpendicular to the plane and positioned along the body between the root and the one or more end flanges.

4. The reinforced door of claim 3 , wherein the one or more end flanges comprise two end flanges, wherein the two end flanges define a gap, and wherein the gap extends along the longitudinal direction parallel with the second edge.

5. The reinforced door of claim 4 , wherein the end cap comprises two slots proximate to the proximal edge, wherein the slots are arranged to accept insertion of the two end flanges, and wherein when the two end flanges are inserted into the slots, the end cap is connected with the body.

6. The reinforced door of claim 5 , wherein the end cap further comprises an internal cavity distal of the proximal edge.

7. The reinforced door of claim 1 , wherein a plurality of fasteners extend through the root and into the rail to fix the body with the rail.

8. The reinforced door of claim 7 , wherein the root comprises a notch extending in the longitudinal direction, wherein the notch facilitates insertion of the fasteners through the root.

9. The reinforced door of claim 1 , further comprising one or more brackets and a plurality of fasteners, wherein a first end the bracket is secured with the member by a first fastener extending through the bracket, through at least one surface of the end cap, and through the body and wherein a second end of the bracket is connected with the door by a second fastener extending through the bracket and into a stile of the door.

10. The reinforced door of claim 1 , further comprising:
a stile connected with the rail and extending perpendicular to the longitudinal direction in a plane of the door;
a bracket; and
a plurality of fasteners, wherein a first end the bracket is secured with the reinforcement member by a first fastener extending through the bracket, through at least one surface of the end cap, and through the body of the member and wherein a second end of the bracket is connected with the panel by a second fastener extending through the bracket and into the stile.

11. The reinforced door of claim 10 , further comprising a second rail, wherein the stile further comprises a plurality of stiles, wherein the stiles extend between the rail and the second rail to define one or more openings.

12. The reinforced door of claim 11 , wherein the one or more openings comprise a glazing panel and wherein the glazing panel is fixed to the plurality of stiles, the rail, and the second rail by a glazing bead.
