Abstract
Abstract An insulated door is made of removable modular panels integrally attached together through a continuous border frame and end covering. The panels are also joined together by a wooden spline inserted into the confronting ends of adjacent panels. A method of repairing an insulated door made of modular panels having a wooden border frame and an end covering joining the panels as well as wooden splines joining the confronting ends of two adjacent panels, comprising cutting the wooden joinder splines, end coverings and border frames, removing the damaged panel, removing the wooden spline from the remaining adjacent panel, cutting back the border frame for a first distance along opposite edges of the remaining panel, cutting back the end covering a greater distance on the opposite edges of the remaining panel, splicing a new panel to the remaining adjacent panel by inserting a new spline, restoring the integrity of the border frame and end covering by providing an extension of the border frame and end covering on the new panel to correspond to the lengths removed from the adjacent remaining panel, and bonding and mechanically fastening the new panel to the remaining adjacent panel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
111 words
A method of replacing modular door panels, each having an insulating rigid foam core, face sheets on opposite sides of the core, structural wood border frames bounded by an end covering, and wood splines joining abutting panels, comprising: cutting the end coverings, structural wood border frames and spline joinder holding the damaged panel to the adjacent panel, removing the damaged panel, removing the severed half of the spline from the remaining adjacent panel, inserting a new spline in the remaining adjacent panel and joining the new panel and spline to the remaining adjacent panel, and restoring the structural integrity of the border frame and end covering to form a completed door.
Claim 2
Independent Claim
111 words
A method of replacing modular door panels, each having an insulating rigid foam core, face sheets on opposite sides of the core, structural wood border frames bounded by an end covering, and wood splines joining abutting panels, comprising: cutting the end coverings, structural wood border frames and spline joinder holding the damaged panel to the adjacent panel, removing the damaged panel, removing the severed half of the spline from the remaining adjacent panel, inserting a new spline in the remaining adjacent panel and joining the new panel and spline to the remaining adjacent panel, and restoring the structural integrity of the border frame and end covering to form a completed door.
Claim 3
Dependent Claim
24 words
The method of claim 1, including attaching a gap closure batten between the confronting ends of the remaining adjacent panel and the new panel.
Claim 4
Dependent Claim
107 words
The method of claim 1, said step of restoring the structural integrity of the border frame and end covering including removing a portion of the length of the adjacent end of the border frame of the remaining adjacent panel, removing a longer portion of the adjacent end covering of the remaining adjacent panel, adding to the new panel an integral end covering and an integral border frame extending from the new panel respective lengths corresponding to the removed lengths of the end covering and border frame of the adjacent panel, and securely fastening the extended length of end covering and border frame to the remaining adjacent panel.
Claim 5
Dependent Claim
28 words
The method of claim 3, said step of securely fastening the extended lengths of end covering and border frame to the remaining adjacent panel including bonding abutting surfaces.
Claim 6
Dependent Claim
56 words
The method of claim 4, the end covering having opposite flanges overlying the face sheets of the panels, said step of securely fastening the extended lengths of end covering and border frame to the remaining adjacent panel including driving mechanical fasteners through the end covering flanges, through the side face sheets and into the foam core.
Claim 7
Dependent Claim
56 words
The method of claim 3, the end covering having opposite flanges overlying the face sheets of the panels, said step of securely fastening the extended lengths of end covering and border frame to the remaining adjacent panel including driving mechanical fasteners through the end covering flanges, through the side face sheets and into the foam core.
Claim 8
Dependent Claim
142 words
A lightweight, modular panel, insulated door comprising: a plurality of modular panels, each having a rigid insulation foam core, a wooden structural border frame extending along free ends of each panel and protruding into the ends of the panel, face sheets on opposite sides of the foam core, end coverings covering the border frame and having opposite side flanges overlying each face sheet to a depth adequate to overlie the foam core, means for fastening the border frame, face sheets and end covering to the foam core, said fastening means including mechanical fasteners abutting against the outside surface of the flanges of the end coverings and extending through the face sheets and a substantial distance into the foam core, said fasteners being located at closely spaced intervals around the door, and means for joining adjacent panels to form a rigid integral door.
Claim 9
Dependent Claim
142 words
A lightweight, modular panel, insulated door comprising: a plurality of modular panels, each having a rigid insulation foam core, a wooden structural border frame extending along free ends of each panel and protruding into the ends of the panel, face sheets on opposite sides of the foam core, end coverings covering the border frame and having opposite side flanges overlying each face sheet to a depth adequate to overlie the foam core, means for fastening the border frame, face sheets and end covering to the foam core, said fastening means including mechanical fasteners abutting against the outside surface of the flanges of the end coverings and extending through the face sheets and a substantial distance into the foam core, said fasteners being located at closely spaced intervals around the door, and means for joining adjacent panels to form a rigid integral door.
Claim 10
Dependent Claim
22 words
The door of claim 7, said means for joining adjacent panels including a spline bonded to the confronting cores of adjacent panels.
Claim 11
Dependent Claim
44 words
The door of claim 8, said means for joining adjacent panels including extending the border frames and end covering of aligned panel ends to cover the entire door so that ends of the panels are joined by a continuous border frame and end covering.
Claim 12
Dependent Claim
44 words
The door of claim 7, said means for joining adjacent panels including extending the border frames and end covering of aligned panel ends to cover the entire door so that ends of the panels are joined by a continuous border frame and end covering.
