DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

[0020] Exemplary embodiments of the present invention are directed to a component for forming a portion of frame, door, trim piece, or the like. Exemplary embodiments also include a method for manufacturing such a component.

[0021] An exemplary embodiment of the component may be used to form an original portion of a frame, door, trim piece, or the like. Alternatively, an exemplary embodiment of a component may be used to replace a damaged portion of a frame, door, trim piece, or the like. For instance, if a portion of a frame, door, trim piece, or the like is rotting or has other water damage, the damaged portion may be removed and replaced with an exemplary embodiment of a component of the present invention.

[0022] FIGS. 1-9 show an exemplary embodiment of a component 10 that is connected to a frame member 100. Component 10 may be connected to frame member 100 in any suitable manner. For instance, adhesives, mechanical fasteners, or other suitable means for connecting wood, metal, plastic, or composite components may be used. While this is an example of a framing use, the same connection principles apply for other framing, door, trim piece, or the like, uses. Furthermore, for other uses, an exemplary component may have any suitable exterior appearance for the intended use of the component.

[0023] In particular, an exemplary embodiment of a component 10 is comprised of a body 12 that may have a suitable shape for use with a door, frame, trim piece, or the like. In this exemplary embodiment, the body 12 has a first end 14 and a second end 16. Such as shown in FIG. 1, first end 14 is adapted to be connected to a portion of a frame, door, trim piece, or the like (e.g., frame member 100). In this example, first end 14 forms a finger joint 18 (herein, finger joint shall be understood to mean one side of a finger joint, unless otherwise specified). Finger joint 18 may be formed during the original manufacturing of component 10, or may be subsequently formed in component 10 by a machining process. In other embodiments, a first end may have any other suitable shape to facilitate connection to a portion of a frame, door, trim piece, or the like. On the other hand, second end 16 is substantially flat in this exemplary embodiment. In other embodiments, a second end may have any suitable shape, including but not limited to a shape to facilitate connection to another component.

[0024] As most clearly shown in FIG. 7, body 12 is comprised of at least one interior hollow portion 20 that forms an opening 22 at first end 14, such as where generally indicated in FIGS. 2 and 9. Thus, in this example, the openings 22 extend up through finger joint 18. The cross-sectional view of FIG. 7 shows openings 22 extending below first end 14. Such as can be seen in the example of FIG. 7, the interior hollow portions 20 occupy an entire cross-sectional area of first end 14, which facilitates a reduction in the amount of material required to make component 10 as compared to a solid component. In other embodiments, the at least one interior hollow portion may be positioned differently or less throughout a cross-sectional area of body 12, yet may still facilitate a reduction in the amount of material required to make component 10 as compared to a solid component.

[0025] More particularly, in this exemplary embodiment, the at least one interior hollow portion 20 extends between lateral sides 30 and 32 of body 12, wherein lateral sides 30 and 32 extend between first end 14 and second end 16. As can be seen in FIG. 7, the hollow portions 20 extend in a direction parallel to lateral sides 30 and 32. The body 12 further comprises at least one transverse member 36 that extends between lateral sides 30 and 32 to form at least one interior hollow portion 20, as well as stabilize the sides of body 12. In addition, at least one dividing member 38 may extend through at least one transverse member 36 to further stabilize body 12 and facilitate the formation of at least one additional interior hollow portion 20. In other embodiments, an interior hollow portion may extend in another direction relative to the sides of the body. Additionally, in other embodiments, a body may be comprised of any number of transverse or dividing members, or may not include any transverse or dividing members.

[0026] In this example, each interior hollow portion 20 further has at least one closed end (e.g., a bottom and/or top) that is closed such that water is prevented from wicking or otherwise traveling from the second end 16 through an interior hollow portion 20 to first end 14. More particularly, in this example, the bottoms of the interior hollow portions 20 are at second end 16 such that the bottoms are interconnected to form the substantially flat bottom surface at second end 16. In another embodiment, the tops of the interior hollow portions may be interconnected to form a substantially flat top surface of a component. Also, in another exemplary embodiment, the bottom or top of at least one interior hollow portion may be positioned intermediately between first end 14 and second end 16. Also, in other embodiments, the closed ends (e.g., bottoms or tops) may be positioned at different levels, if desired.

[0027] FIG. 10 shows another exemplary embodiment of a component 200 of the present invention. Component 200 may be similar to component 10, with the exception that component 200 has a first end 202 that is substantially flat. This exemplary embodiment of component 200 may be used as is to be connected to a frame, door, trim piece, or the like. In particular, similar to component 10, component 200 may be connected to another component such as with adhesives, mechanical fasteners, or other suitable means for connecting wood, metal, plastic, or composite components.

[0028] Component 200 may also be post-processed to facilitate connection to a frame, door, trim piece, or the like. Such as mentioned with respect to component 10, component 200 may be initially formed as shown in FIG. 10, and then may be later subjected to a machining process to facilitate the formation of a desired joint or other shape at first end 202. For example, component 200 may be machined to form finger joint 18 of component 10. Any suitable machining process may be used for the type of material from which component 200 is made. In one example, conventional wood processing equipment (such as for making frames, doors, trim pieces, or the like) may be used to further form component 200 (not limited to first end 202) into a desired joint or other shape.

[0029] FIG. 11 illustrates yet another embodiment of a component 300 of the present invention. Component 300 may be similar to components 10 and 200, with the exception of a different configuration for further facilitating one desired use of a fastener 302 (e.g., such as for securing component 300 to a support structure). Fastener 302 may also be inserted in an opposite direction through component 300, if desired. Component 300 may include a receptacle that is pre-formed to facilitate a desired use of a fastener, or a fastener may simply be used with a component without any pre-formed receptacles. In other embodiments, other types of mechanical fasteners, adhesives, or other suitable means for connecting wood, metal, plastic, or composite components may be used to secure a component of the present invention to a support structure (e.g., a wall, door sill, foundation, frame, etc.).

[0030] In light of the at least one hollow portion having a closed end, preferred methods of manufacturing may include injection molding, 3D printing, and multi-step extrusion. Such manufacturing processes may facilitate the formation of the closed end(s) of the at least one interior hollow portion. In some exemplary embodiments, injection molding may also facilitate the formation of a finger joint (e.g., finger joint 18) or other type of joint, shape, or aesthetic feature. However, unless otherwise specified, other suitable types of manufacturing may be used to manufacture a component of the present invention. For instance, in the event that an exemplary component of the present invention is not made from a material that is amenable to injection molding, another suitable type of manufacturing may be implemented to make the exemplary component.

[0031] As aforementioned, an exemplary component of the present invention is preferably manufactured from a rot-resistant material. For example, an exemplary embodiment of a component may be comprised of plastic, plastic composite, metal, or another rot-resistant material. In some preferred embodiments, a plastic or plastic composite may be utilized, which may facilitate manufacturing by injection molding. In such instances, any suitable type of plastic (e.g., polymer) may be used. Examples of polymer may include, but are not limited to, polyvinyl chloride (PVC), polyethylene, and polypropylene. Examples of fillers for a plastic composite may include, but are not limited to, organic fillers (e.g., cellulosic filler and other plant matter) and inorganic fillers (e.g., glass, inorganic fibers, and minerals). Other additives may be implemented. However, unless otherwise specified, a component of the present invention may be made from any suitable material, including materials that may not be rot-resistant.

[0032] Any embodiment of the present invention may include any of the optional or preferred features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. Having shown and described exemplary embodiments of the present invention, those skilled in the art will realize that many variations and modifications may be made to the described invention. Many of those variations and modifications will provide the same result and fall within the spirit of the claimed invention. It is the intention, therefore, to limit the invention only as indicated by the scope of the claims.
