Abstract
Abstract A raised panel door has a center panel surrounded by four inner border members which in turn are surrounded by four outer border members. Said panel and border members have a plastic face sheet and a relatively thick backer of inexpensive material. The said center panel is rabbeted around its periphery, and the four inner border members taper in thickness from the latter outwardly, the thicker edge portions extending into the center panel rabbets and the thinner edge portions extending into rabbets formed in the outer border members. A flat support is attached to the assembled center panel and said border members, forming a unitary whole.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
79 words
A panel door comprising a center panel having a rabett at its periphery, four inner border members next to the sides of said center panel and tapering in thickness outwardly therefrom, said panel thicker portion entering said rabbet, and four outer border members next to said inner border members each having a rabbet at one side, said panel thinner portion entering said latter rabbets, and a flat support attached to the face surfaces of inner and outer border members.
Claim 2
Dependent Claim
79 words
A panel door comprising a center panel having a rabett at its periphery, four inner border members next to the sides of said center panel and tapering in thickness outwardly therefrom, said panel thicker portion entering said rabbet, and four outer border members next to said inner border members each having a rabbet at one side, said panel thinner portion entering said latter rabbets, and a flat support attached to the face surfaces of inner and outer border members.
Claim 3
Dependent Claim
57 words
A panel door as of claim 1, said panel and border members each having a top surface, face sheet of relatively hard and thin material, and each having a backer of relatively soft and thick material, said rabbets being located solely in said panel and outer border member backers whereby said face sheets overhang said latter backers.
Claim 4
Dependent Claim
21 words
A panel door as of claim 2 said face sheets being of plastic and said backers being of a woody material.
Claim 5
Dependent Claim
36 words
A panel door as of claim 2, said face sheets being substantially 1/16 inch thick, said outer border member backers being substantially 6/16 inch thick and said inner border member backers being substantially 5/16 inch thick.
Claim 6
Dependent Claim
75 words
A panel door as of claim 2, said outer border members each having a side surface face sheet extending angularly from said top surface face sheet to a point where said rabbets in said outer border members commence, said center panel thinner portions extending directly under said side face sheets and being of such overall thickness that said outer backer and panel under surfaces are in horizontal alignment and thereby present a flat, even surface.
Claim 7
Dependent Claim
24 words
A panel door as of claim 2, said center panel being of rectangular shape, said inner and outer border members being of oblong shape.
Claim 8
Dependent Claim
39 words
A panel door as of claim 5, said inner border member backers being thinner at their maximum thickness than said panel and outer border member backers, said panel and outer border member backers being of substantially uniform thickness throughout.
Claim 9
Dependent Claim
36 words
A panel door as of claim 7, said inner border members being thinner at their maximum thickness than said panel and outer border members, said panel and outer border member backers being of uniform thickness throughout.
Claim 10
Independent Claim
124 words
A method of assembling a panel door commencing with a center panel having a rabbet at the outside edge, placing inner border members which taper in thickness in contact with the periphery of said center panel with the thicker side extremities of said inner border members extending into said center panel rabbet, then placing outer border members, which have each a rabbet at their inner side extremities, in contact with said inner border members with the thinner side extremities of the latter extending into the said rabbets of the said outer bordEr members, and then placing a flat support on the assembled center panel, inner border members and outer border members, and attaching said flat support to them to thereby form a unitary panel.
Claim 11
Independent Claim
124 words
A method of assembling a panel door commencing with a center panel having a rabbet at the outside edge, placing inner border members which taper in thickness in contact with the periphery of said center panel with the thicker side extremities of said inner border members extending into said center panel rabbet, then placing outer border members, which have each a rabbet at their inner side extremities, in contact with said inner border members with the thinner side extremities of the latter extending into the said rabbets of the said outer bordEr members, and then placing a flat support on the assembled center panel, inner border members and outer border members, and attaching said flat support to them to thereby form a unitary panel.
Claim 12
Dependent Claim
94 words
A method of assembling a panel door as of claim 9, said center panel, said inner border and outer border members each having a plastic face sheet and a backer thicker than said face sheet, said rabbets in said center panel and said outer border members being formed solely in their respective said backers, placing the plastic face sheets of said inner border members on the undersurface of said center panel plastic face sheet, and the plastic faces of said thinner side extremities of said inner border members into said outer border member rabbets.
Claim 13
Dependent Claim
59 words
A method of assembling a panel door as of claim 10, said outer border members each having an angularly extending plastic face sheet at one side surface thereof, said outer border member rabbets extending beyond said angular face sheets, and placing the ends of said outer border angular face sheets on the face sheets of said inner border members.
