Description
METHOD OF AND SYSTEM FOR
THE MANUFACTURE AND INSTALLATION OF
PREFABRICATED WINDOW TRIM AND CASING SYSTEMS
INCLUDING AN ADJUSTABLE CUTTING GUIDE
FIELD OF THE INVENTION
This invention relates to the field of window trims and casings. More particularly, this invention relates to a method of and system for the manufacture and installation of prefabricated window trim and casing systems, whereas the apparatus for installing includes an adjustable cutting guide.
BACKGROUND OF THE INVENTION
Often it is desired to trim and case a window opening, on its interior side, in various manners through the use of jambs, headers, sills, stools, casings, or aprons.
Window trim and casings serve to increase the beauty and the energy efficiency of window units. Further, the window trim and casings enhance the practical usefulness of the sill or stool area of the window units and are typically installed during new construction of a building or during replacement of existing windows.
During new construction, a window trim and casing is installed around a rough opening formed within and defined by the frame of a building structure.
In retrofit applications, replacement window trim and casings are often installed around an existing window opening, either during renovation of the structure or during replacement of the structure's windows.
Current window trim and casings used in new and retrofit applications require a great degree of skill and time to measure, custom fabricate, and install.
Under current practice, trimming and casing interior window openings require a skilled finish carpenter working at a job-site to individually measure, cut. fit, and install each individual piece of trim and casing for each individual window opening. This current process has numerous disadvantages including: (1 ) the high hourly cost of a finish carpenter; (2) the great amount of time required to carry out this procedure for each individual window opening; (3) the entire procedure must be performed at the job-site, often an occupied residence, disrupting the normal routine, order, and cleanliness of the job-site for an extended period of time; (4) due to varying skill levels and output productivity of finish carpenters, there are variations in quality and efficiency of the end result; (5) the time and cost associated with the need to smooth, square, or otherwise prepare the sides and face of the window opening for the proper acceptance of the trim and casing components; and (6) the sawdust, discarded materials, and refuse created as a result of carrying out this process at the job-site.
SUMMARY OF THE INVENTION
A method of and apparatus for installing prefabricated window trim and casing systems including an adjustable cutting guide apparatus is disclosed.
The current invention allows for the accurate, repeatable manufacture of window trim and casing assemblies in a controlled manufacturing environment on a high production 1 S and high quality basis. The current invention also provides a quick, simple, clean, accurate, and economical method of installing the prefabricated window trim and casing apparatus into the interior side of any window opening. The preferred prefabricated window trim and casing apparatus is a decorative molding for interior applications and comprises a casing subassembly configured to cover a window opening and a customizable jamb subassembly coupled to the rear of the casing subassembly. The casing subassembly is preferably configured to cover a window opening in an interior wall. The customizable jamb subassembly comprises a customizable jamb depth and is configured to be inserted into the window opening and fastened to the wall.
The customizable jamb subassembly allows custom installation of the window trim and casing into window openings with unique jamb depth dimensions. The unique dimensions are a result of typical construction variations such as, for example, variations in overall wall thickness, plastering, window frame positioning, window design/style variations, and window manufacturing tolerances. The jamb depth dimension varies, in some cases, by inches from one window opening to the next.
The current invention provides for a method, useable at the job-site, for quick, simple, accurate, and economical customization of the jamb depth dimension of the prefabricated window trim and casing apparatus to match that of the window opening into which the assembly is to be installed.
An adjustable cutting guide apparatus used for customizing and installing the prefabricated window trim and casing apparatus is also disclosed. The preferred adjustable cutting guide apparatus comprises a guiding region, with the guiding region comprising a fenestrated planar deck. The adjustable cutting guide apparatus is configured to detachably couple to a base plate of a portable power cutting tool, preferably an electric saw comprising a cutting region, such that the guiding region is positioned outside of, and not interfering with, the cutting region.
Specifically, the guiding region is configured to detachably couple through the base plate of the electric saw, preferably through mounting slots. The mounting slots allow the adjustable cutting guide apparatus to couple with base plates of various portable power cutting tools. The guiding region is configured to rest against the customizable jamb subassembly of the prefabricated window trim and casing apparatus. Once coupled, the planar deck and the guiding region configures the cutting region so the cutting region aligns the blade of the electric saw with the customizable jamb subassembly and the blade evenly trims the customizable jamb subassembly to a desired thickness.
Preferably, the prefabricated window trim and casing apparatus comprises wood. In alternative embodiments, the prefabricated window trim and casing apparatus comprises polyvinyl chloride. In further alternative embodiments, the prefabricated window trim and casing apparatus comprises fiberglass. In yet other embodiments, the prefabricated window trim and casing apparatus comprises insulating material providing for greater heat gain protection and energy efficiency.
The configuration of the prefabricated window trim and casing apparatus varies to meet the needs of the consumer, the particular end use application, or the type of installation to be used also in a hollow configuration. For example, embodiments of the prefabricated window trim and casing apparatus include, but are not limited to, picture frame, full-bound, double-hung, rectangular, full casing, or awning configurations.

FIG. 8 illustrates an exemplary flow chart 800 detailing a method of manufacturing a prefabricated window trim and casing apparatus, in accordance with the instant invention. The prefabricated window trim and casing apparatus is preferably configured to cover an opening in an interior wall. At the step 801, a jamb subassembly comprising vertical frame jambs; a head frame, and a frame sill is fabricated. In alternative embodiments, a jamb subassembly comprising a stool instead of the frame sill is fabricated. At the step 802 .a casing subassembly is fabricated. The casing subassembly preferably comprises vertical side casings, a horizontal top casing, and a horizontal bottom casing. In the step 803 the casing subassembly is coupled to the customizable jamb subassembly to form the prefabricated window trim and casing apparatus. The method of manufacturing a prefabricated window trim and casing system ends at the step 804.
The current invention provides a high speed, high quality, and low cost way to mass manufacture window trim and casings at a manufacturing facility. These prefabricated window trim and casings can be quickly installed by low skilled laborers, yet still achieve a consistent carpentered look. Further, the current invention provides ease of installation, lower manufacturing cost, reduced labor costs, ease in cleaning and maintenance, as well as a wide choice of colors, materials, and designs.
Other advantages of the current invention include compatible and customizable window trim and casings and installation methods for both new construction and replacement (retrofit) applications. The prefabricated window trim and casing apparatus is versatile in design and flexible in configuration parameters so as to meet both the infinite variation of window opening dimensions which exist and the broad range of features/aesthetics/materials which are demanded in the marketplace.
The prefabricated window trim and casing system and corresponding method for Installation do not require the skills of a finish carpenter but instead can be readily installed by the typical lower wage window installer or any equivalent lower skilled worker. Further, the method of installing the prefabricated window trim and casing apparatus applies for any window opening regardless of whether the window opening is in a rough, semi-finished, or finished state and with no need for smoothing, squaring, or other preparation of the side surfaces or front surfaces of the window opening.
Further, the adjustable cutting guide apparatus disclosed is sturdy, inexpensive, and readily adaptable to the broad range of portable power cutting tools that currently exist in the construction industry. Use of the adjustable cutting guide apparatus, in conjunction with the system, is simple for the typical window installer to understand with the aid of only cursory directions or a simple instruction sheet. Also, the adjustable cutting guide apparatus is easily removable from the portable power I S cutting tool so as not to require the installer to dedicate a tool exclusively for a single use.
Unlike existing adjustable cutting guide apparatuses, the current adjustable cutting guide apparatus provides a power cutting tool with a guide surface located on the inboard side of the cutting blade of the portable power cutting tool. In other words, existing adjustable cutting guide apparatuses provide a portable power cutting tool with a guide surface located on the outboard side of the cutting blade of the portable power cutting tool. Existing adjustable cutting guide apparatuses with guide surfaces located on the outboard side of the cutting blade of the portable power cutting tool limit the usefulness of the guide and the power cutting tool because the motor and its associated housing extend outwardly from the inboard side of the portable power cutting tool. This outward extension acts as an obstruction and hinders or eliminates the cutting of an exposed edge of a surface in close proximity to any obstruction protruding from that surface, such as a flange or a wall.
Another advantage of the current adjustable cutting guide apparatus is that it is configured to allow a user to reverse the conventional orientation of a portable power cutting tool relative to the item being cut, eliminating any problem of interference between the motor and,its associated housing.of the portable power cutting tool with an object to be trimmed.
The method, apparatus, system, and associated adjustable cutting guide apparatus offer substantial benefits and significant reduction in the amount of material, time, and cost required for a wide range of window trim and casing installations. The current invention provides for low cost production and installation, and allows for a method of rapid, repeatable, high quality fabrication employing typical methodology and industrial machinery that is commonly, readily, and economically available in the woodworking, plastics, and metals industries.
The present invention has been described in terms of specific embodiments incorporating details to facilitate the understanding of the principles of construction and operation of the invention. Such reference herein to specific embodiments and details thereof is not intended to limit the scope of the claims appended hereto. It will be apparent to those skilled in the art that modifications may be made in the I 5 embodiment chosen for illustration without departing from the spirit and scope of the invention.

FIG. 8 illustrates an exemplary flow chart 800 detailing a method of manufacturing a prefabricated window trim and casing apparatus, in accordance with the instant invention. The prefabricated window trim and casing apparatus is preferably configured to cover an opening in an interior wall. At the step 801, a jamb subassembly comprising vertical frame jambs; a head frame, and a frame sill is fabricated. In alternative embodiments, a jamb subassembly comprising a stool instead of the frame sill is fabricated. At the step 802 .a casing subassembly is fabricated. The casing subassembly preferably comprises vertical side casings, a horizontal top casing, and a horizontal bottom casing. In the step 803 the casing subassembly is coupled to the customizable jamb subassembly to form the prefabricated window trim and casing apparatus. The method of manufacturing a prefabricated window trim and casing system ends at the step 804.
The current invention provides a high speed, high quality, and low cost way to mass manufacture window trim and casings at a manufacturing facility. These prefabricated window trim and casings can be quickly installed by low skilled laborers, yet still achieve a consistent carpentered look. Further, the current invention provides ease of installation, lower manufacturing cost, reduced labor costs, ease in cleaning and maintenance, as well as a wide choice of colors, materials, and designs.
Other advantages of the current invention include compatible and customizable window trim and casings and installation methods for both new construction and replacement (retrofit) applications. The prefabricated window trim and casing apparatus is versatile in design and flexible in configuration parameters so as to meet both the infinite variation of window opening dimensions which exist and the broad range of features/aesthetics/materials which are demanded in the marketplace.
The prefabricated window trim and casing system and corresponding method for Installation do not require the skills of a finish carpenter but instead can be readily installed by the typical lower wage window installer or any equivalent lower skilled worker. Further, the method of installing the prefabricated window trim and casing apparatus applies for any window opening regardless of whether the window opening is in a rough, semi-finished, or finished state and with no need for smoothing, squaring, or other preparation of the side surfaces or front surfaces of the window opening.
Further, the adjustable cutting guide apparatus disclosed is sturdy, inexpensive, and readily adaptable to the broad range of portable power cutting tools that currently exist in the construction industry. Use of the adjustable cutting guide apparatus, in conjunction with the system, is simple for the typical window installer to understand with the aid of only cursory directions or a simple instruction sheet. Also, the adjustable cutting guide apparatus is easily removable from the portable power I S cutting tool so as not to require the installer to dedicate a tool exclusively for a single use.
Unlike existing adjustable cutting guide apparatuses, the current adjustable cutting guide apparatus provides a power cutting tool with a guide surface located on the inboard side of the cutting blade of the portable power cutting tool. In other words, existing adjustable cutting guide apparatuses provide a portable power cutting tool with a guide surface located on the outboard side of the cutting blade of the portable power cutting tool. Existing adjustable cutting guide apparatuses with guide surfaces located on the outboard side of the cutting blade of the portable power cutting tool limit the usefulness of the guide and the power cutting tool because the motor and its associated housing extend outwardly from the inboard side of the portable power cutting tool. This outward extension acts as an obstruction and hinders or eliminates the cutting of an exposed edge of a surface in close proximity to any obstruction protruding from that surface, such as a flange or a wall.
Another advantage of the current adjustable cutting guide apparatus is that it is configured to allow a user to reverse the conventional orientation of a portable power cutting tool relative to the item being cut, eliminating any problem of interference between the motor and,its associated housing.of the portable power cutting tool with an object to be trimmed.
The method, apparatus, system, and associated adjustable cutting guide apparatus offer substantial benefits and significant reduction in the amount of material, time, and cost required for a wide range of window trim and casing installations. The current invention provides for low cost production and installation, and allows for a method of rapid, repeatable, high quality fabrication employing typical methodology and industrial machinery that is commonly, readily, and economically available in the woodworking, plastics, and metals industries.
The present invention has been described in terms of specific embodiments incorporating details to facilitate the understanding of the principles of construction and operation of the invention. Such reference herein to specific embodiments and details thereof is not intended to limit the scope of the claims appended hereto. It will be apparent to those skilled in the art that modifications may be made in the I 5 embodiment chosen for illustration without departing from the spirit and scope of the invention.
