Abstract

The present invention is directed to a door panel preferably for a sliding door assembly. The door panel includes an inner frame and a sheet stock substantially covering the inner frame. The inner frame includes a geometry that cooperates with a geometry of a door accessory for operable connection of the door accessory directly to the inner frame.

Claims

1. A door panel for a slidable door assembly including a drive system, the door panel comprising:

an inner frame including multiple frame members forming an upper edge, a lower edge, and opposing side edges of the door panel, wherein each frame member has

a substantially identical cross section,

at least two integrally formed outer face surfaces,

a first outer edge and a second outer edge integrally formed,

at least one of a first receptacle or a first protrusion formed in one of the first outer edge or the second outer edge, the first receptacle or protrusion of each frame member extending along an entire length of the first or second outer edge and being exposed along one of the upper edge, the lower edge, or one of the opposing side edges of the door panel so that one receptacle or protrusion is exposed at each of the upper edge, lower edge, and opposing side edges of the door panel;

an accessory including a surface having a receptacle or protrusion that cooperates with the first receptacle or protrusion of one of the multiple frame members to connect the accessory directly to the inner frame; and

sheet stock, the sheet stock substantially covering the outer face surfaces of each of the multiple frame members as well as a portion of the first or second outer edge of each of the multiple frame members, the portion of the sheet stock covering the outer edge of each of the multiple frame members not covering any portion of the first receptacle or protrusion extending along the first or second outer edge of the frame member.

2. The door panel of claim 1 wherein the accessory is a trolley.

3. The door panel of claim 1 wherein the accessory is a leading edge gasket.

4. The door panel of claim 1 wherein the accessory is a trailing edge gasket.

5. The door panel of claim 1 wherein the accessory is a guide mechanism.

6. The door panel of claim 5 further comprising a bottom edge gasket, the bottom edge gasket being coupled directly to the guide mechanism.

7. The door panel of claim 1 wherein the accessory connects to the inner frame using a press fitting.

8. The door panel of claim 1 wherein the accessory connects to the inner frame using a snap fitting.
