Abstract
Abstract The invention disclosed relates to raised or lowered panel assemblies, such as raised panel doors, as employed in cabinets and furniture. The frame is constructed of pre-shaped molding having an inner section of reverse taper and an integral thicker outer section. The frame is comprised of four pieces of molding assembled as stiles and rails of the door and joined at mitered corners. The molding is rabbeted along the inner edge and receives a flat center panel formed with a projecting tongue or groove and lip. The molding and center panel are preferably formed having a core composite of wood composition or chip board. The core is wrapped or covered with a surface layer of a plastic, preferably thermosetting, material which simulates a wood veneer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A panel assembly comprising, a center panel of a core material having a thin layer attached to at least one surface thereof, four frame members next to the sides of said center panel, each of said four frame members including an inner reverse taper portion and an integral outer portion, said inner reverse taper portion having a thicker section disposed adjacent said center panel and a thinner portion adjacent said integral outer portion, each of said four frame members comprising a core material having a thin surface layer attached to at least one surface thereof, said four frame members having abutting and connected ends forming a four sided frame, said four sided frame defining a continuous connector means on its inner periphery, the outer periphery of said center panel defining mating means received by said continuous connector means for securing and holding said center panel in a self supporting relationship, relative to said four sided frame, said continuous connector means and said mating means comprising at least one continuous groove and at least one projection received by said groove.
Claim 2
Dependent Claim
179 words
A panel assembly comprising, a center panel of a core material having a thin layer attached to at least one surface thereof, four frame members next to the sides of said center panel, each of said four frame members including an inner reverse taper portion and an integral outer portion, said inner reverse taper portion having a thicker section disposed adjacent said center panel and a thinner portion adjacent said integral outer portion, each of said four frame members comprising a core material having a thin surface layer attached to at least one surface thereof, said four frame members having abutting and connected ends forming a four sided frame, said four sided frame defining a continuous connector means on its inner periphery, the outer periphery of said center panel defining mating means received by said continuous connector means for securing and holding said center panel in a self supporting relationship, relative to said four sided frame, said continuous connector means and said mating means comprising at least one continuous groove and at least one projection received by said groove.
Claim 3
Dependent Claim
34 words
The panel assembly of claim 1 in which the center panel is of a thickness so as to be in a raised relationship with the face of said outer portion of four sided frame.
Claim 4
Dependent Claim
34 words
The panel assembly of claim 1 in which the center panel is of a thickness so as to be in a lowered relationship with the face of said outer portion of four sided frame.
Claim 5
Dependent Claim
31 words
The panel assembly of claim 1 in which the face of the center panel lies substantially in the plane of the face of said outer portion of said four sided frame.
Claim 6
Dependent Claim
37 words
The panel assembly of claim 1 in which said continuous connector means comprises a continuous groove defined by said frame and said mating means comprises a continuous projection on said center panel, said groove engaging said projection.
Claim 7
Dependent Claim
64 words
The panel assembly of claim 1 in which said continuous connector means and said mating means include a first groove defined on said inner periphery of said frame, a second groove defined by said outer periphery of said center panel, a first projection on said center panel received by said first groove and a second projection on said frame received by said second groove.
Claim 8
Dependent Claim
19 words
The panel assembly of claim 1, in which said frame members are connected to one another by mitered joints.
Claim 9
Dependent Claim
211 words
A panel door assembly comprising, a center panel of a core material having a thin layer attached to at least one surface thereof, four frame members next to the sides of said center panel, each of said four frame members including an inner reverse taper portion and an integral outer portion, said inner reverse taper portion having a thicker section disposed adjacent said center panel and a thinner portion adjacent said integral outer portion, each of said four frame members comprising a core material having a thin surface layer attached to at least one surface thereof, said four frame members having abutting joints forming a four sided frame, said four sided frame defining a continuous connector means on its inner periphery, the outer periphery of said center panel defining mating means complementary with said continuous connector means for securing and holding said center panel in a self supporting relationship, relative to said four sided frame, said continuous connector means and said mating means including a first rabbet defined on said inner periphery of said frame, a second rabbet defined by said outer periphery of said center panel, a first projection on said center panel received by said first rabbet and a second projection on said frame received by said second rabbet.
Claim 10
Dependent Claim
211 words
A panel door assembly comprising, a center panel of a core material having a thin layer attached to at least one surface thereof, four frame members next to the sides of said center panel, each of said four frame members including an inner reverse taper portion and an integral outer portion, said inner reverse taper portion having a thicker section disposed adjacent said center panel and a thinner portion adjacent said integral outer portion, each of said four frame members comprising a core material having a thin surface layer attached to at least one surface thereof, said four frame members having abutting joints forming a four sided frame, said four sided frame defining a continuous connector means on its inner periphery, the outer periphery of said center panel defining mating means complementary with said continuous connector means for securing and holding said center panel in a self supporting relationship, relative to said four sided frame, said continuous connector means and said mating means including a first rabbet defined on said inner periphery of said frame, a second rabbet defined by said outer periphery of said center panel, a first projection on said center panel received by said first rabbet and a second projection on said frame received by said second rabbet.
