Abstract
Abstract A rigid building component such as a door, table top or the like, is formed of coarse wooden particles mixed with adhesive, and a solid wooden edge frame, positioned between a pair of damp, substantially parallel, cellulosic fiber webs. A heated press is employed to compact the combination, particularly between the edge frame and the cellulosic fiber webs where the coarse wooden particles are greatly compressed to provide a durable edge. Under the heat and pressure applied in the press the particles are consolidated into a solid structure, while the damp cellulosic fiber webs are converted to tough exterior skins bonded to the coarse wooden particles. The sides of the rigid building component are suitably deeply embossed to provide a decorative paneled appearance.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
A rigid building component comprising: a core of consolidated and compacted coarse wooden particles disposed between a pair of substantially parallel densified outer skins of cellulosic fibers firmly bonded to said core, said coarse wooden components including adhesive material coated thereupon and dispersed throughout said rigid building component for adhering said particles into a solid structure, and an interior solid wood edge frame positioned within said coarse wooden particles around the peripheral edge of said building component, said edge frame extending completely around said building component and comprising a pair of stiles on either side of said building component joined by a pair of rails at the upper and lower edges of said building component, each of said stiles and rails comprising a board of predetermined thickness having flat sides substantially parallel to said outer skins, the coarse wooden particles between the sides of said boards and said outer skins being compacted to have a density substantially greater than the density of said wooden particles located centrally of said building component within said solid wood edge frame to provide solid durable wooden edges adjacent said edge frame around the periphery of said building component.
Claim 2
Dependent Claim
194 words
A rigid building component comprising: a core of consolidated and compacted coarse wooden particles disposed between a pair of substantially parallel densified outer skins of cellulosic fibers firmly bonded to said core, said coarse wooden components including adhesive material coated thereupon and dispersed throughout said rigid building component for adhering said particles into a solid structure, and an interior solid wood edge frame positioned within said coarse wooden particles around the peripheral edge of said building component, said edge frame extending completely around said building component and comprising a pair of stiles on either side of said building component joined by a pair of rails at the upper and lower edges of said building component, each of said stiles and rails comprising a board of predetermined thickness having flat sides substantially parallel to said outer skins, the coarse wooden particles between the sides of said boards and said outer skins being compacted to have a density substantially greater than the density of said wooden particles located centrally of said building component within said solid wood edge frame to provide solid durable wooden edges adjacent said edge frame around the periphery of said building component.
Claim 3
Dependent Claim
29 words
The rigid building component according to claim 1 further including deeply embossed portions within said edge frame in registry with which said coarse wooden components have an intermediate density.
Claim 4
Dependent Claim
199 words
A rigid building component comprising: a core of consolidated and compacted coarse wooden particles disposed between a pair of substantially parallel densified outer skins of cellulosic fibers firmly bonded to said core, said coarse wooden components including adhesive material coated thereupon and dispersed throughout said rigid building component for adhering said particles into a solid structure, and an interior solid wood edge frame positioned within said coarse wooden particles around the peripheral edge of said building component, the coarse wooden particles between the sides of said edge frame and said outer skins being compacted to have a density substantially greater than the density of said wooden particles located centrally of said building component within said solid wood edge frame to provide solid durable edges adjacent said edge frame around the periphery of said building component, said solid wood edge frame comprising a first pair of parallel wooden stiles grooved at their respective ends to receive a pair of wooden rails joining said stiles, said rails being narrower in transverse dimension than said stiles wherein the wooden particles between said stiles and said outer skins have a greater density than the wooden particles between said rails and said outer skins.
Claim 5
Dependent Claim
199 words
A rigid building component comprising: a core of consolidated and compacted coarse wooden particles disposed between a pair of substantially parallel densified outer skins of cellulosic fibers firmly bonded to said core, said coarse wooden components including adhesive material coated thereupon and dispersed throughout said rigid building component for adhering said particles into a solid structure, and an interior solid wood edge frame positioned within said coarse wooden particles around the peripheral edge of said building component, the coarse wooden particles between the sides of said edge frame and said outer skins being compacted to have a density substantially greater than the density of said wooden particles located centrally of said building component within said solid wood edge frame to provide solid durable edges adjacent said edge frame around the periphery of said building component, said solid wood edge frame comprising a first pair of parallel wooden stiles grooved at their respective ends to receive a pair of wooden rails joining said stiles, said rails being narrower in transverse dimension than said stiles wherein the wooden particles between said stiles and said outer skins have a greater density than the wooden particles between said rails and said outer skins.
