Description

BACKGROUND

1. Technical Field

The present disclosure relates to door systems and, more specifically, to edge banding of door stiles for door systems.

2. Discussion of Related Art

Door systems can include door panels with glass panels inserted within and supported by the door panel. A door panel includes stiles surrounding each of the glass panels that support and seal the glass panel within the door panel.

With reference to FIGS. 1 and 2, a prior art door stile 10 can be formed of a core 20. The core 20 may be formed of inner layers 22 of wood that are bonded together to form a solid core. The outer layers 24 of the core 20 may be a phenolic layer that enhances adhesion of paint to the core 20. The inner layers 22 and/or outer layers 24 may be bonded together by adhesives disposed between the layers 22, 24. The core 20 is capped on an outer side or edge with an outer edge band 30 and on an inner side or edge with an inner edge band 40. The outer edge band 30 and the inner edge band 40 may be bonded to the core by an adhesive. The outer edge band 30 and the inner edge band 40 may be solid wood or may be several pieces of wood finger jointed together to form a continuous edge band.

The outer edge band 30 and the inner edge band 40 may be generally rectangular when bonded to the core 20 as shown by the outer lines in FIG. 1 and be machined or profiled to the final profile to what is shown in the dashed lines. The final profile of the outer edge band 30 and the inner edge band 40 can be seen in FIG. 2.

As shown, the outer edge band 30 and the inner edge band 40 are formed of wood. In use, when the door stile 10 is exposed to an exterior of a structure, such as when part of an exterior door, the outer edge band 30 and the inner edge band 40 may be exposed to the environment. As a result, the outer edge band 30 and the inner edge band 40 may be susceptible to decay. Decay of the outer edge band 30 and the inner edge band 40 may result in a loss of a seal about the glass panel and/or the outer edge of the door stile 10. Decay around the glass panel may result in the glass panel becoming unseated from the door panel. As such, there is need to seal the outer edge band 30 and the inner edge band 40 to prevent decay.

Referring now to FIG. 3, a method 100 of manufacturing a door stile is detailed in accordance with the present disclosure and with reference to the door stile 200 of FIGS. 4 and 5. The door stile 210 includes composite edge bands 230, 240 that are bonded to a core 220 to seal the core 220. The composite edge bands 230, 240 are paintable and not susceptible to decay.

To manufacture the door stile 210, a core 220 is formed of layers 222 that are bonded together to form a solid block of material (Step 110). When formed, the core 220 may include a phenolic layer 224 as the external layers of the core 220. The phenolic layers 224 may be sanded and may seal the external faces of the core 220. The core 220 may be cut to a width such that the core 220 has an exterior side 226 and an interior side 228 opposite the exterior side 226 (Step 120). The exterior side 226 and the interior side 228 may be substantially linear such that when viewed on end the core 220 is substantially rectangular as shown in FIG. 4. The core 220 may be similar to the core 20 detailed above.

With the core 220 trimmed, a composite edge band 230, 240 is bonded to each of the exterior side 226 and the interior side 228 of the core 220 (Step 130). To bond the composite edge bands 230, 240 to the core 220, an adhesive may be disposed along the exterior side 226 and the interior side 228 of the core 220 and/or the sides of the edge bands 230, 240 that oppose the core 220 (Step 132). With the adhesive disposed, the composite edge bands 230, 240 are positioned along the exterior side 226 and the interior side 228 of the core 220, respectively, such that the composite edge bands 230, 240 extend the entire length of the core 220 (Step 134). With the edge bands 230, 240 positioned, the edge bands 230, 240 are compressed towards one another with the core 220 disposed therebetween (Step 136). The composite edge bands 230, 240 are similar to one another and each extend a full length of the core 220. The external profile of each of the composite edge bands 230, 240 is substantially rectangular when bonded to the core 220. With particular reference to FIG. 4, the composite edge bands 230, 240 include one or more hollows 234, 244 that extend the length of the composite edge bands 230, 240. The hollows allow the composite edge bands 230, 240 to flex along the sides 226, 228 of the core 220 to provide a consistent surface to bond to the core 220. The flexing of the composite bands 230, 240 during bonding may enhance the bond between the composite bands 230, 240 and the core 220.

With the composite bands 230, 240 bonded to the core 220, the composite bands 230, 240 and the core 220 are profiled to a final profile of the door stile 210 (Step 140). When the composite bands 230, 240 are profiled, the portion of the edge bands 230, 240 defining the hollows 234, 244 are machined away such that the portion of the edge bands 230, 240 remaining are substantially solid and bonded to the core 220 along the respective one of the sides 226, 228 as shown in FIG. 5.

The composite bands 230, 240 may have a constant profile along the entire length of the door stile 210 or may have a first profile adjacent the top and bottom ends of the door stile 210 and a different profile in another portion of the length of the door stile 210. For example, the profile of the door stile 210 may be profiled along a portion thereof to receive a glass panel as shown in FIG. 5 with a portion of the length above and below the glass panel being profiled to support and retain the glass panel within the door stile 210 and to form a final profile of the door panel.

While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Any combination of the above embodiments is also envisioned and is within the scope of the appended claims. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. Those skilled in the art will envision other modifications within the scope of the claims appended hereto.
