Provisional Application Serial No. 60/116,098, filed January 15, 1999.

BACKGROUND OF THE INVENTION Door frame structures typically are formed as separate structures and then installed at the construction site. The frame structure typically includeS a three sided piece (top and two sides), from which a door is hung. The structure is inserted into an appropriate doorway opening formed in the home or building under construction.

Door frame structures typically comprise a jamb 15 portion onto which the door hinges are attached. The jamb must be of sufficient strength to hold the heavy door and withstand the punishment typically endured throughout its life. The frame and jamb portion are typically constructed of wood.

Unfortunately, wood and wood-treated structures have a tendency to degrade and warp or rot under outside weather conditions. Thus, efforts have been made to attach vinyl or other types of structures or coatings to the outside of the wood surface to provide protection from the S 25 environment.

One example of such an effort is shown in U.S.

Patent No. 5,758,458 to Ridge. The Ridge patent discloses a door frame assembly that is attachable to a stud or post adjacent a door frame opening. The assembly includes a wood support panel that is attachable to the stud or post. A base strip formed of extruded polymer is attached to and covers the exterior end of the support panel. The base 6842/95 2 strip is attached to the stud by nails driven through a fin that extends outwardly from the base strip.

A stop strip of extruded polymer is mounted adjacent to the inner face of the support panel and attached to the support panel. The base strip and the stop strip are separately formed as distinct pieces. The hollow centers and thin panels of the extruded strips in the Ridge patent indicate the use of rigid polymer, such as rigid polyvinyl chloride.

The present invention involves the use of vinyl attachments to the wood jamb that are formed of cellular or foamed polymer to provide an attractive, yet environmentally protected door frame and jamb.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a door frame and, in particular, a door frame jamb made of wood and cellular or foamed vinyl plastic. The plastic portions are attached to the wood jamb along the outside of the frame.

A door and frame, such as used in the present invention, is shown in Figure 4. The door 10 is held onto .frame 12 by a pair of hinges 14, 16. The frame 12 includes horizontal portion 18 and two vertical or jamb portions o S. 15 20, 22. The horizontal and vertical portions are preferably i preformed to include the present invention. The door 10 is then hung onto the frame and the entire structure inserted and fixed within an appropriate opening at a residential or commercial construction site.

The details of the portions of the door frame jamb i of the present invention are shown in Figures 1-3. Figure 1 provides a perspective view of the frame members from the interior of the jamb. Figure 3 provides a perspective view :i of the frame members from the exterior of the jamb. Figure 25 2 provides a plan view of the section shown in Figures 1 and 3.

As shown in Figures 1-3, the door frame 12 includes wood jamb portion 24, which is attached to the wood structure of the door opening. Hinges 14, shown in Figure 4, are attached to jamb portion 24. A vinyl extender portion 26 is attached to the end of jamb portion 24. Vinyl extender 26 may be formed of polyvinyl chloride (PVC) or any of a number of suitable plastics that can be extruded or 6842/95 5 injection molded. Preferably, vinyl extender 26 is formed from cellular or foamed plastic, which includes a blowing agent to cause expansion of the piece upon leaving the extruder. Cellular plastic permits formation of a solid (non-hollow) vinyl extender piece of appropriat6 configuration.

The vinyl extender 26 is preferably formed with a series of notches or steps 28, 29, which allow attachment of the extender 26 to the wood jamb 24. A vinyl extension piece 30 may also be used to hold the end 32 of the wood jamb 24. The wood jamb is preferably cut with a notch 34 to provide a flush mounting for the extension piece 30. The extension piece 30 may be formed of rigid (non-cellular) or cellular plastic on account of its limited width. The *oo.

15 extension piece is attached to the vinyl extender by glue, ooo.

nails, screws or other attachment mechanisms known in the art.

A flexible foam weatherstrip 38 is preferably placed between the wood jamb 24 and the extender 26. The e 20 weatherstrip forms a seal between the edge of the door (not shown in Figures 1-3) and the wood jamb 24. The side panels 42 of the extender 26 and extension piece respectively, have a smooth surface to provide an attractive ornamental look to the extender.

25 The vinyl extender 26 is attached to a vinyl brick molding piece 44 at the end opposite of the wood jamb. The brick molding piece is also preferably formed of cellular or foamed plastic in order to provide a material of the proper thickness and necessary configuration.
