Patent Application
20140345216
This invention relates broadly to cornerbead/corneraide products and related tools and methods for finishing corners of sheetrock/drywall (or other materials) on walls, to enable builders and owners to create distinctive, comfortable, and beautiful rooms and buildings. As indicated herein, the inventions disclosed herein can be used in a broad range of applications and provide many benefits.
Although many other applications exist for the invention, some examples include in connection with or “as” chair rail, crown moulding, window/doorway trim, and exterior applications. Any of the many configurations of the “central web” or “face” portion of the cornerbead of the invention can be used with varying attachment/connections wing profiles, as may be appropriate and/or useful for each application.
Although products embodying and/or incorporating the invention can be fabricated from any suitable material and by any suitable method, convenient approaches include conventional vinyl/extrusion and/or metal/roll-form processes.
These and other embodiments will become readily apparent to those skilled in the art from the following detailed description of embodiments having reference to the attached figures, the invention not being limited to any particular preferred embodiment(s) disclosed.
As indicated above, the inventions disclosed herein can be used in a broad range of applications and provide many benefits. Embodiments of the present invention will now be described with references to the accompanying figures, wherein like reference numerals refer to like elements throughout.
Persons of ordinary skill in the art will understand that the apparatus of the invention and variations of its many methods can be practiced using any of a wide variety of suitable processes and materials.
Certain of the drawings illustrate how the underlying material (wallboard, sheetrock, etc.) may be held back slightly from the relevant edge of the corner assembly, to make use of various embodiments of the invention even more conveniently. Depending on the particular size of the embodiment, any such “holdback” distance may vary, or may not be needed. If needed, the sheetrock at the corners can easily be cut back to allow selection and use from a wide range of embodiments. Some of the drawings show a series of exemplary section views to illustrate how supporting materials (framing, wallboard, sheetrock, etc.) may be positioned to provide even further options in the use of the invention. The size of the desired finishing product embodiment can affect the need for and/or amount of “holdback”: relatively smaller profiles may require no “special” holdback from the corner (of those supporting materials); larger profiles may require some degree of setback.
In addition to use in new construction, the inventions can be used for remodeling projects. For remodeling projects, existing sheetrock at the corners typically easily can be cut back (to achieve any needed “holdback”), and the framing at the corner can be trimmed back to accommodate larger sizes.
Persons of ordinary skill in the art will understand that, in addition to walls that reach from a room's floor to ceiling, the invention can be used on half-walls and other “partial” structures. Room dividers and similar structures, for example, may use a “three-way” version of the invention to help join wallboard or other material that is disposed on three or more different planes.
Some of the many benefits, objects, and advantages of the inventions include the following, which may or may not be present in any given embodiment of the inventions:
Virtually all of the embodiments of the invention can be adapted into a wide range of applications, and can be used in various combinations or exclusively throughout a building or home. For example, the crown moulding, chair rail, window and door frames, and exterior corners can all incorporate one or more embodiments of the invention. Within a single building or project, the selected cross-section can be the same for ALL of those elements that may be present, or a plurality of cross-sections may be used, intermixed with each other, or otherwise configured to provide a desired result.
For certain applications (for example, inside corners, such as on a windowsill as illustrated above), the ends of the pieces can be angled or otherwise shaped (during production or on the jobsite) to permit 2-way, 3-way, and other corners/joints. Such angles can be provide on one or both ends of a given piece, and multiple angles (such as the “double 45” degree cuts shown in
As mentioned above, comparing the various cross-sections in FIGS. 7.1-7.7 helps illustrate the wide range of sizes and applications for the invention, and the flexibility that a given embodiment may have for different specific applications. For example, in a relatively “standard” wallboard corneraide configuration above (½ inch wall board extending only to the edge of the support framing), the dimensions for the illustrated cornerbead can vary depending on designer or customer specifications or other factors.
Among the many alternative applications of the invention, the sheetrock can be different thicknesses, and/or the sheetrock or even the support framing can be “held back” further from the corner. By doing so, larger sizes of channels or other shapes can be utilized at the joint. Examples of such approaches are shown below in
Although all of FIGS. 7.1-7.7 have illustrated just one general cross-sectional embodiment of the invention, the same principles preferably apply with respect to other such embodiments. Similarly, the various dimensions discussed herein and for the wings, thicknesses and other aspects of the apparatus can vary beyond those illustrated. The designs can be modified for applications on angles other than 90 degrees, can be positioned asymmetrically/unbalanced, and/or can otherwise be adjusted for custom applications.
Although the examples above focus on some of the many ways that the invention can be installed and enjoyed for interior finishes, it also can be readily sized and adapted for exterior applications (corners, eaves, etc.).
By way of example and not by way of limitation, certain embodiments of the apparatus can be manufactured via processes using one or more steps of injection molding, gluing, bonding, shaping, milling, drilling, injection molding, thermo-forming, casting, and many other existing and new processes that may come into being. Materials are not limited in any way and could extend to include at least certain parts of the apparatus being made from metals to plastics, to resins of all types. A preferred material is lightweight, non-corrosive and will hold up to the exposure anticipated in its eventual usage (including by way of example, chemical reagents, chlorinated water, acidic water, salt water, marine environments, UV exposure, etc.). A preferred method of manufacture is by injection molding and coloring various components of the embodiments, and by machining others and/or buying them from commercially-available sources.
As mentioned above, the designs of the invention can be adapted into crown moulding and similar trim pieces. For certain applications (for example, inside corners, such as on a windowsill), and as shown in some of the drawings, it may be useful to provide a 45 degree angle on one or both ends.
Without changing the wallboard or support structures, the channel dimensions can vary across a range of width and depth combinations. Cross-Sections 7.3, 7.4, and 7.5 illustrate just a few of those combinations. In Cross-Section 7.3, keeping the channel depth approximately the same as in 1 and 2 (⅛″), the channel width can be up to approximately ½″. In Cross-Section 7.4, keeping the channel width approximately the same as in 1 and 2 (⅛″), the channel depth can be up to approximately ¼″. In Cross-Section 7.5, the channel width is 5/16″, and the channel depth is 3/16″).
Among the many alternative applications of the invention, the sheetrock can be different thicknesses, and/or the sheetrock or even the support framing can be “held back” further from the corner. By doing so, larger sizes of channels or other shapes can be utilized at the joint. Examples of such approaches are shown below in Cross-Sections 7.6 and 7.7 (with channels that are 3/16″× 5/16″, and 15/16″× 15/16″, respectively).
Although all of Cross-Sections 7.1-7.7 have illustrated an exemplary shape, the same principles apply with respect to other embodiments of the invention. Similarly, the various dimensions discussed herein and for the wings, thicknesses and other aspects of the designs can vary beyond those illustrated. The designs can be modified for applications on angles other than 90 degrees, can be positioned asymmetrically/unbalanced, and/or can otherwise be adjusted for custom applications.
In addition to the sample applications discussed herein, many others exist, including corneraide-type pieces (such as discussed herein) being built into or added onto the following items:
