2 Sheets-Sheet 2 o, It mrnon or RAIS PANEL 1,
The principal object of my invention is to eliminate the usual milling or cutting away a whole piece of wood to thereby leave a raised center panel that is surrounded by a sunken portion. This is especially desirable when the panel has a face of a hard, tough plastic such as that known under the name Formica, making it impractical to make a raised center panel in the usual way.
Another object is to make the panel door of pieces of material that are simple and inexpensive to cut to the desired shape and which can be assembled by merely moving the pieces into contact with each other and then uniting them to a flat supporting sheet, so the plastic sheets cover the entire exposed faces of the door.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts, and a method of manufacture, such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I am not to be limited to the particular construction disclosed by the drawings nor to that described in the specification; but am entitled to all such changes therefrom as fall within the scope of my invention.

As illustrated, my panel door has a center panel 10 that has a backer 14 of relatively thick and inexpensive and relatively soft material such as coreboard, or a material made of pressed wood or sawdust, and a binder, which gives depth to my door. It is covered, on one side at least, with a relatively thin face sheet of a hard, durable and preferably decorative plastic F-l, such as that sold under the name Formica, being attached as by cement. Said plastic sheet F-l may be I/ l 6 inch thick, for instance, and said backer M may be 5/16 inch thick. Whenever a member is covered by said thin sheet of said plastic I identify it in each instance by the letter F with a numeral. Said center panel Ill has a rabbet or cut-out l5 made in said backer 14 completely around it, so that said plastic sheet F-l overhangs said backer l4.
Surrounding said center panel Ill are four inner border members, the two extending vertically, as shown, being called inner stiles 16 that have a relatively thick backer of coreboard ll6a similar to said backer 14 that is covered by a said plastic face sheet F -2. The two that extend crosswise are called inner rails 17 that also have a relatively thick backer of said coreboard 17a, that is covered by a said plastic face sheet F-3. The ends of these stiles and rails extend diagonally in the usual way as at 18 and the four members adjoin each other to define a rectangle. Said stiles and rails taper in thickness from said center panel 10 laterally outward, the taper occurring in the coreboard as at 16a and 17a only. The inner or thicker edge extends into said rabbet 15 so that said plastic sheet F-ll overhangs said four inner boarder members 36 and 17.
Surrounding said inner members 16 and 17 are four outer border members which I refer to as two outer stiles 24 and two outer rails 28. Said outer stiles have a relatively thick backer 25 of said coreboard that is covered by a said plastic face sheet F4. Also a narrow side, face strip of plastic sheet F-5 is preferably used and it extends angularly downward from said sheet F -4, for only part of the thickness of said backer 25. There is a rabbet or cut-out 26 made in said backer 25 so that said side sheet F-5 overhangs the cut portion of said backer 25.
Said outer rails 28 have a backer 29, similar to backer 25, that is also covered by a said plastic face sheet F-6 and a narrow side face strip of plastic sheet F 7 extends angularly downward from said sheet F-6. There is a rabbet 30 made in said backer 29 similar to rabbet 26. Said side sheets F-5 and F-7 may be 4/16 inch wide, and said rabbets 26 and 39 may be 2/16 inch wide, for instance. The thinner portions of said inner border members may be 2/l6 inch thick where they enter said rabbets 26 and 30, hence the under surfaces of said outer border members and said thinner portions present a flat even surface.
The outer or end portions of said inner stiles 16 and inner rails 17, which are relatively thin, extend into said rabbets 26 and 30 respectively, so that said plastic sheets F-S and F-7 overhang portions of said inner stiles and inner rails respectively. 7
Said center panel 19, said inner members 16 and 17, and said outer members 24 and 28 are inverted when assembled, as described above, and are unitarily supported by a flat support 32 which may be made of coreboard. This is done by resting the faces of said coreboard backers 14, 16a, 17a, 25 and 29 thereon, and cementing or otherwise attaching these nine members to said support 32. Said plastic sheets F-l, F-2, F- 3, F4 and F-5 are at the bottom at this point, and by turning over said support 32 they will be in view with only said plastic sheets showing. A rabbet 34 is shown cut in said support 32 in said FIGS. 1 and 2, to provide for a hinge, if desired.
Said inner and outer border members are thicker overall than said center panel overall. For instance, said backers of these members may be 6/16 inch compared to the thickness of said panel backer 14 which may be 5/16 inch as stated above. Said center panel and outer border members are preferably of the same thickness, hence when my door panel is completely assembled the under face surfaces of all parts present an even flat surface which said support 32 rests flatly upon. My method of assembling a panel door of parts such as those above described, commences by laying on a flat table or board said center panel upside down, that is, with said backer 14 at the top. Said tapered inner border members 16 and 17 are also laid upside down the thicker side extremities being inserted into said rabbets 15, with said plastic sheets F-2 and F-3 resting on the under side of said plastic sheet F-l.
Said outer border members 24 and 28 are then laid, upside down, next to said inner border members 16 and 17, bringing into contact the thinner side extremities of said members 16 and 17 with said outer border members 24 and 28 by having said thinner side extremities enter said rabbets 26 and 30 thereby resting angularly extending plastic sheets F-6 and E7 on the latter thinner side extremities.
A flat support 32 is then laid on the above assembly and said center panel 10, said inner border members 16 and 17, and said outer border members 24 and 28 are then joined together as by an adhesive, or by driving nails through said support 32 and partly into said panel and border members. The panel so formed is turned right side up so only the plastic sheets are visible as shown on said FIG. 1.
