Abstract

An exemplary door includes a door body and a light assembly. The door body includes a first door panel defining a first panel opening, a second door panel defining a second panel opening, and an internal cavity. The area of the first panel is greater than the area of the second panel opening. The light assembly includes a first trim, a second trim, and an impact-resistant pane positioned in the door cavity. The first trim includes an outer frame coupled to the first door panel and an inner frame positioned in the internal cavity. The pane has an area greater than the area of the second panel opening area, and includes an first outer layer adhered to the inner frame of the first trim, a second outer layer adhered to the door body, and at least one intermediate layer.

First claim

What is claimed is:

1. A door, comprising:
a door body defining an impact side, a secure side, a plurality of edges, and an internal cavity, the door body having a longitudinal height, a lateral width, and a transverse thickness, the door body comprising:
an impact side door panel defining the impact side of the door body, the impact side door panel defining an impact side panel opening having an impact side panel opening area;
a secure side door panel defining the secure side of the door body, the secure side door panel defining a secure side panel opening having a secure side panel opening area less than the impact side panel opening area;
wherein the impact side door panel is transversely offset from the secure side door panel and the internal cavity is formed therebetween; and
wherein the impact side panel opening is aligned with the secure side panel opening; and

a light assembly mounted to the door body, the light assembly comprising:
an impact side trim mounted to the impact side door panel, the impact side trim including an outer frame coupled to the impact side door panel, an intermediate frame extending transversely through the impact side panel opening, and an inner frame positioned in the internal cavity, wherein the inner frame defines an impact side trim opening aligned with the secure side panel opening;
a secure side trim mounted to the secure side door panel, the secure side trim including a secure side trim opening aligned with the secure side panel opening;
an impact-resistant pane positioned in the door cavity, the pane having a pane area greater than the secure side panel opening area, the pane comprising a plurality of layers adhered to one another, wherein the plurality of layers comprises an impact side outer layer adhered to the inner frame of the impact side trim, a secure side outer layer adhered to the door body, and at least one intermediate layer located between the first outer layer and the second outer layer; and
a plurality of fasteners coupling the impact side trim and the secure side trim to the door body.

2. The door of claim 1 , wherein each of the layers of the pane has the pane area.

3. The door of claim 1 , wherein the impact side outer layer is adhered to the inner frame of the impact side trim by a first adhesive device, and the secure side outer layer is adhered to the door body by a second adhesive device different from the first adhesive device.

4. The door of claim 3 , wherein the first adhesive device comprises at least one first strip of a double-sided adhesive tape, and wherein the second adhesive device comprises at least one bed of a glazing material.

5. The door of claim 4 , wherein the double-sided adhesive tape comprises a foam having a first adhesive side and a second adhesive side.

6. The door of claim 4 , further comprising at least one second strip of the double-sided adhesive tape adhering the impact side trim to the impact side panel, and at least one third strip of the double-sided adhesive tape adhering the secure side trim to the secure side panel.

7. The door of claim 4 , further comprising at least one bead of the glazing material forming a seal between an inner edge of the impact side trim opening and the impact side outer layer of the pane.

8. The door of claim 4 , wherein the secure side outer layer further comprises an anti-spall film formed on the glass layer of the secure side outer layer, and wherein the at least one bed of glazing material is adhered to the anti-spall film.

9. The door of claim 1 , wherein the door body further comprises a bracket assembly including a plurality of brackets; wherein each bracket comprises a base portion, a first flange extending from the base portion by a first distance, and second flange extending from the base portion by a second distance greater than the first distance; wherein the first flanges are coupled to the impact side door panel and at least partially surround the impact side panel opening; and wherein the second flanges are coupled to the secure side door panel and at least partially surround the secure side panel opening.

10. The door of claim 9 , wherein the secure side outer layer is adhered to the second flanges.

11. The door of claim 9 , wherein the bracket assembly further comprises a plurality of slots, wherein each of the slots is formed in one of the base portions, and wherein a corresponding one of the fasteners extends through each of the slots.

12. The door of claim 11 , wherein each of the fasteners comprises a sex bolt having a male bolt and a female bolt threadedly engaged with the male bolt within a corresponding one of the slots.

13. The door of claim 1 , wherein a distance between a lower edge of the secure side panel opening and a bottom edge of the door body is no greater than 43 inches.

14. The door of claim 1 , wherein the pane area is less than the impact side panel opening area.

15. The door of claim 1 , wherein each of the impact side outer layer and the secure side outer layer comprises a glass layer, and wherein the at least one intermediate layer comprises a polycarbonate layer.

16. A method, comprising:
preparing a door body including a first door panel, a second door panel, and an internal cavity formed between the first door panel and the second door panel, wherein the first door panel includes a first panel opening having a first panel opening area, wherein the second panel includes a second panel opening having a second panel opening area greater than the first panel opening area, and wherein the second panel opening is aligned with the first panel opening;
preparing a light assembly, wherein preparing the light assembly includes:
preparing a first trim including a first trim opening having a first trim opening area corresponding to the first panel opening area;
preparing a second trim including a second trim opening area corresponding to the first trim opening area, wherein the second trim includes an outer frame, an inner frame defining the second trim opening, and an intermediate frame sized and configured to be received in the second panel opening;
preparing an impact-resistant pane having a pane area greater than the first panel opening area, the pane comprising a plurality of layers adhered to one another, wherein the plurality of layers comprises a first outer layer, a second outer layer, and at least one intermediate layer located between the first outer layer and the second outer layer, wherein each of the first outer layer and the second outer layer comprises a glass layer, and wherein each of the at least one intermediate layers comprises a polycarbonate layer;

mounting the light assembly to the door body, wherein mounting the light assembly to the door body comprises:
inserting the pane into the door cavity through the second panel opening;
adhering the first outer layer of the pane to the door body with a first adhesive device; and
