Abstract
The disclosed door and method for manufacturing the same allows a door manufacturer to more easily fabricate custom sectional overhead doors. The disclosed door and method for manufacturing the same eliminates the expense of having a skilled craftsman hand mill and fit each trim hoard. The disclosed door and method for manufacturing the same enables fabricating infinite designs and infinite sizes without the constraint of being limited to preset, expensive platens/dies for fabrication. The disclosed door and method for manufacturing the same provides for routing typical depth panels into a door without having to penetrate various layers of the door. The disclosed door and method for manufacturing the same provides a solid core of insulation which is not subject to routing which decreases thermal resistively of the door.
Claims21
A sectional overhead door comprising:
- plural height-wise adjacent door sections, including a bottom section, at least one intermediate section and a top section, each having substantially the same width;
- said sections each comprising:
- a unitary face panel having a front surface and a planar rear surface;
- and
- a planar core assembly that comprises a hollow center frame having a uniform thickness;
- said center frame comprising plural rails and stiles;
- wherein a front surface of said core assembly supports said rear surface of said face panel;
- and
- each face panel in said intermediate section and one or both of said top and bottom sections having a portion of a unitary face panel design, said unitary design comprising grooves routed into said panel front surfaces such that the unitary design is provided without utilizing trim boards on said panel front surfaces, said routed design groves not extending into said core assembly;
- wherein at least a plurality of the design grooves continuously span at least height-wise over said intermediate section and said one or both of said top and bottom sections, such that when said plural door sections are height-wise aligned in a closed-door configuration, the unitary design is provided.
