BACIZGROUND 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 niece ;top and two sidesi, =rom 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 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 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 strip is attached tc 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 hollcw 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.
SUI~HARY OF THE INVENTION
