Description

WOOD JAMBA AND VINYL FOR DOOR FRAME RELATED REQUEST The present application claims the benefit of the US patent application serial number 60 / 116,098, filed on January 15, 1999.

BACKGROUND OF THE INVENTION Doorframe structures are typically formed as separate structures and then installed at the construction site. The structure for door frame typically includes a third side piece (top and two sides), from which a door hangs. The structure is inserted into an appropriate door opening in a house or building under construction. Door frame structures typically comprise a jamb portion on which the door hinges are fixed. The jamb must be strong enough to hold the heavy door and resist the adverse conditions it faces 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 weather conditions. Therefore, efforts have been made to fix vinyl or other types of structures or coatings to the exterior of the wood surface to provide protection from the environment. An example of such an effort is shown in Ridge's U.S. Patent. The Ridge patent discloses a door frame assembly that can be attached to a stud or post adjacent to a door frame opening. The assembly includes a wooden support panel that can be fixed to the pillar or post. A base strip formed of extruded polymer is fixed to the outer end of the support panel and covers it. The base strip is fixed to the upright by means of nails through a flap extending outwardly from the base strip. An extruded polymer stop strip is mounted adjacent to the inner face of the support panel and fixed to the support panel. The stop strip and the retainer strip are formed separately as separate parts. 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 jointing means to the wooden jamb, which are made of cellular or foamed polymer to provide an attractive door and jamb frame and at the same time protected from environmental conditions.

BRIEF DESCRIPTION OF THE INVENTION In one embodiment, a door frame jamb assembly is provided to hold a door. The frame jamb assembly is constructed as an integral unit to be transported to the construction site and to be fixed to a door frame opening. The frame assembly consists of several pieces. One piece is the jamb portion, which is made of wood and is the portion that is fixed to the opening of the door frame. The jamb portion has an inner end and an outer end, which faces the inside and outside of the door opening, respectively. A second portion of the frame assembly is a rigid vinyl extension portion. The spreading portion is made of cellular resin in a solid piece (not hollow). The vinyl extension portion has a first end with a notch formed therein to receive the outer end of the jamb portion. The outer end of the jamb portion is firmly fixed to the notch of the vinyl extension portion. A third piece or portion of the frame assembly is a rigid block molding portion, which is also made of cellular resin. The block molding portion has a notch formed in it so that the second end of the vinyl extension portion is received in the notch and is firmly fixed thereto.

The jamb assembly for door frame also includes a protective strip of the environment, foam, flexible, which is firmly secured between the jamb portion and the vinyl extension portion. In one embodiment, the second end of the vinyl extension portion is formed in a tab configuration. The notch formed in the block molding portion is formed in a slot configuration to coincide with the tab configuration. In one embodiment, the wooden jamb portion has a notch formed along its inner end. The vinyl attachment piece is fixed between the jamb portion and the vinyl extension portion in the notch. The foam protection strip acts to cover the fixing between the jamb portion and the door frame opening. The block molding portion is also located adjacent the outer end of the jamb portion. Its outer surface faces the exterior of the door frame assembly and provides a smooth surface for ornamental purposes. The block molding portion also includes a slot containing a plastic flap for insulation purposes.

DESCRIPTION OF THE PREFERRED MODALITIES The present invention provides a door frame and, in particular, a door frame jamb, made of wood and cellular foamed or vinyl plastic. The plastic portions are attached to the wooden jamb along the outside of the frame. A door and frame, as used in the present invention, is shown in Figure 4. The door 10 is held on the frame 12 by means of a pair of hinges 14, 16. The frame 12 includes a horizontal portion 18 and two vertical or jamb portions 20, 22. The horizontal and vertical portions are preferably formed to include the present invention. The door 10 is then hung over the frame and the entire structure is inserted and fixed within an appropriate opening in a residential or commercial construction site. The details of the portions of the door frame jamb of the present invention are shown in Figures 1-3. Figure 1 provides a perspective view of the frame members of the interior of the jamb. Figure 3 provides a perspective view of the frame members on the outside of the jamb. Figure 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 a jamb portion 24 of wood, which is attached to the structure of the door. wood of the door opening. To the jamb portion 24 are fixed hinges 14, which are shown in Figure 4. A vinyl extension portion 26 is fixed to the end of the jamb portion 24. The jamb extender 26 may be formed of polyvinyl chloride ( PVC) or any number of suitable plastics that can be extruded or molded by injection. Preferably, the vinyl extender 26 is formed of cellular or foamed plastic, which includes a blowing agent to produce the expansion of the piece upon leaving the extruder. The cellular plastic allows the formation of a piece of vinyl extender (not hollow) of appropriate 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 can also be used to hold the end 32 of the wooden jamb 24. The wooden jamb preferably has a notch 34 to provide a flush mount for the extension piece 30. The extension piece 30 may be formed of a rigid (non-cellular) or cellular plastic, which represents its limited width. The extension piece is fixed to the vinyl extender with glue, nails, screws or other fixation mechanisms known in the art. A flexible, foam, environmental protection strip is preferably placed between the wooden jamb 24 and the extender 26. The environmental protection strip forms a seal between the door edge (not shown in FIGS. 3) and the wooden jamb 24. The side panels 40, 42 of the extender 26 and the extension piece 30, respectively, have a smooth surface to provide an attractive ornamental appearance to the extender. The vinyl extender 26 is attached to a piece of vinyl block molding 44 at the opposite end of the wooden jamb. The block molding piece is also preferably made of foamed or foam plastic in order to provide a material of the proper thickness and the necessary configuration. The extender may include a tongue piece 46 which fits inside a coupling slot 48 of the block molding piece 44. Other types of connection joints between the extender 26 and the block molding 44. Other types of connection connections between the extender 26 and the block 44 molding. The connection between the pieces can be made with glue or staples or other appropriate connection means. The block molding provides the part of the door frame that faces the outside of the door or building and is exposed to the environment. The block molding 44 preferably includes a smooth surface 50 to provide an attractive ornamental piece. The block molding can be made of polyvinyl chloride or any other plastic suitable for extrusion or injection molding, but preferably it is made of cellular plastic. The block molding 44 may include a notch or slot 52 to include a plastic flap 54. The flap 54 may be fixed to the sides or other portions of the door. The wooden jamb portion 24 is fixed to the opening by means of nails through the piece 24. The nails can be placed near the piece of protective strip against the environment, whereby said strip acts to cover the nails and isolate them so they can not be seen. Therefore, the door frame of the present invention provides a wooden jamb 24 with a vinyl plastic extender 26 and a block molding piece 44. The frame provides an attractive exterior vinyl plastic trim fixed to the part of conventional wooden jamb. The wooden piece jamb can be nailed to the door opening in the conventional manner. Extruded or molded frame parts provide a strong frame product that avoids the difficulties involved in attaching strips or vinyl frames to a door frame during the installation of the door and frame.
