FLEXIBLE MATERIAL FLOORING MITER DEVICE AND SYSTEM FOR FLEXIBLE MATERIAL FLOORING INSTALLATION
A device and method for the proper installation of flexible flooring such as sheet flooring and more particularly the formation of flash coving and proper installation thereof comprising two complementary portions of a guide tool of proper angles and straightedges required to form mitered corner formation and installation.
The present invention generally relates to the field of flexible flooring installation. More specifically, the present invention relates to a device and method for the proper installation of flexible flooring such as sheet flooring and more particularly the formation of flash coving and proper installation thereof.
BACKGROUND OF THE INVENTIONFlexible flooring is commonly utilized as flooring cover in residential and commercial building. Depending on the intended use of a residential or commercial facility, various flooring options are available to the consumer. For example, residential and commercial linoleum, sheet vinyl floor coverings, glue down carpet products and other carpet products including rubber or vinyl backed carpets are commonly utilized in the art.
In fact, the desire to provide floor coverings exhibiting a hard, relatively waterproof surface for shielding the foundations and supporting structures from the daily grind of activities commonplace in the home is long ingrained in our culture. Primitive floor coverings included tampered earth mixed with oxblood which dried to a hard, easily-swept surface. Such floor coverings gave way to the introduction of floor cloths (common rudimentary squares of various cloth substances) in the eighteenth century. Floor cloths were primarily utilized in dining areas and were placed under dining room tables to catch crumbs rather than exposing the crumbs to the unprotected wood floors providing structural support to the domicile. Virtually after every meal, the floor cloths were removed and any debris was transported outside of the domicile as the cloths were shaken to loosen and remove the crumbs from the previous meal.
Over time, the floor cloths were improved upon, and in the early eighteenth century, floor cloths were soon loomed from sturdy coated fabrics. It became commonplace for floor cloths to be manufactured from canvas, hemp, and linen coated with oils or paints providing a virtually water-proof surface. These “oilcloths” were easily made at home and soon mass produced.
Mass produced oilcloths gave rise to the advent of a product now commonly called linoleum. Early linoleum was manufactured from linseed oil, cork gums, and pigment and was designed to exhibit a leather-like texture. Linoleum remained popular into the 1900's as a long-lasting floor covering and soon various floor covering alternatives emerged, including vinyl flooring which exhibited vibrant printed colors molded with a clear vinyl product.
Today, vinyl floor coverings are the prominent floor covering in both residential and commercial applications. Various individual products are known in the art such as residential rotogravure sheet flooring, residential interflex flooring, residential linoleum sheet flooring, residential dry-back tile, commercial linoleum sheet flooring, heterogeneous commercial sheet flooring, heterogeneous commercial tile flooring, homogeneous commercial sheet flooring, homogeneous commercial tile flooring, commercial felt-backed sheet flooring, commercial inlaid sheet flooring, commercial luxury solid vinyl flooring, commercial vinyl composition tile, commercial slip-retardant sheet flooring, and commercial vinyl composition slip-retardant tile, just to name a few. Various manufacturers, including current manufacturers such as Armstrong World Industries, Inc.'s Floor Products unit and Congoleum Corporation, market various products for the aforementioned floor coverings categories under various trademarked names. For example, Armstrong World Industries, Inc.'s commercial linoleum sheet flooring line includes current products marketed under the names: Marmorette®, Granette®, Uni Walton®, Colorette®, Linorette®, Linodur®. Similarly, Armstrong World Industries, Inc.'s commercial solid vinyl sheet flooring line includes current products marketed under the names: Natural Creations® and Natural Options®.
Each of the aforementioned products are manufactured from various common raw materials. For example, the primary components of the aforementioned vinyl floor coverings include polyvinyl chloride (or vinyl) resins, plasticizers (high molecular-weight solvents), pigments and trace stabilizers, and a carrier sheet or backing. The backing generally manufactured of felt or highly filled paper made from wood pulp and calcium carbonate. High-gloss surface vinyl sheets or vinyl tiles have an additional polyurethane coating applied at the end of the process.
In general, the manufacture of vinyl floor coverings involves a series of physical alternations to the various aforementioned raw materials. First, vinyl resins and plasticizers are mixed, creating a slurry commonly referred to as plastisol. A compound consisting of two nitrogen atoms which are united at both ends to separate carbon atoms is added to the base slurry. When the resins, plasticizers, and nitrogen compound is heated, the nitrogen compound decomposes forming nitrogen gas bubbles resulting in a vinyl foam. This foam-based slurry is transferred and spread onto the installation medium or backing. The slurry is placed on the felt or wood pulp backing via a reverse roll coater and adhered via heat application creating a vinyl gel whereby the vinyl resin absorbs the plasticizer. The gel is transferred through a printing press and is impressed, when desired, with metal intaglio plates for creating the carved decorative patterns. A second mixing of plasticizer and vinyl are applied to the printed gel and is transferred through a second heating system resulting in a clear vinyl known as wear layer. This top layer is designed as a protective portion to safeguard the decorative portion of the product. Once the wear layer is adhered, various finishes are applied with consistent thickness and the product is cured. Further, an adhesive layer may be affixed thereto.
Once manufactured and shipped, the floor covering is ready for installation. Depending on the desired size of installation, floor covering utilized, and various other parameters, basic installation is common to the various aforementioned sheet flooring products.
First, the subfloor must be prepared including the removal of any abrasive portions, removal of obstructions, grading of the flooring, the preparation of underlayments, sealing and/or patching of various subfloors, etc. Next the various adhesives are applied and the layout and fitting of the flooring is established.
Once the flooring is installed and fitted, the seams are addressed, often requiring difficult pattern matching of the various flooring products. Once the patterns are matched, seam cutting must be performed. Those of skill in the art will readily recognize that seam cutting is one of the most difficult aspects of sheet flooring installation especially since it is relatively impossible to repair a mis-cut on a seam compared to other fitted regions.
There are three common methods for cutting seams. These include double-cut, recess scribed or underscribe, and straightedge and butt. Double-cut seams are generally used on heterogeneous and felt-backed materials—generally materials which can be cut through two layers with one cut. With a first piece installed and secured, a second piece is pattern matched, and a straightedge cut is made through both pieces of floor covering.
In contrast, recess scribe or underscribe seams are recommended for heavier materials. To perform this type of edge, a first piece is fit in place and straight-edged with a knife. A second piece is overlaid and a recess scriber is set to follow the straight-edged first piece to mark the desired cut. A straightedge knife is utilized to complete the cut along the scribed portion.
The final common cut is the straightedge and butt seam. This seam application is only utilized with certain products and requires aligned patterns of joined flooring which are cut in two distinct passes.
Once the seams are cut, seam coating products are utilized to virtually hide the seams in the materials from common view. In most instances, the seams are further heat welded to provide for a protected, water-resistant seam.
In many instances, the flooring installation is complete at this point. However, additional installation such as flash coving is required in numerous applications. Specifically, in many industrial and commercial institutions, flash coving is required. While many of skill in the art find seams to be a difficult application, flash coving is viewed as the specialty skill that separates a good installer from a great installer. The extensive steps and difficulty of each step with little room for error makes the preparation of flash coving one of the most difficult aspects of installing flexible flooring.
Advancements in utility knifes, scribe knifes, hook blade knifes, rollers, straightedge tools and the like have made various portions of installing sheet flooring easier. However, while numerous inventions and advancements in the art have evolved to assist in the installation of sheet and tile flooring, few inventions have aided an installer with the flash coving aspect of flexible flooring installation.
The need for a device for aiding in the installation of flash coving will be readily apparent based on a review of several disclosures in the art. For example, various flexible flooring cutting tools developed in the art include Prater U.S. Pat. No. 3,395,453 entitled “Carpet Cutter,” Matsushita U.S. Pat. No. 4,001,936 entitled “Carpet Cutter,” Baughman U.S. Pat. No. 4,817,290 entitled “Trimming Tool,” Hyer et. al U.S. Pat. No. 6,112,417 entitled “Precision Vinyl & Carpet Trimmer,” and Taylor et. al U.S. Pat. No. 6,230,410 entitled “Wall Trimmer for Carpet and Vinyl Floor Coverings.”

An improvement to the aforementioned cutters includes Hyer et. al U.S. Pat. No. 6,112,417. While Prater, Matsushita, and Baughman are directed to carpet cutting instruments, the Hyer et al. invention is directed to a device for cutting carpets and vinyl flooring products. Hyer et al. (depicted as
Continuing with the advancements in the art of installing flexible flooring, Taylor et al. U.S. Pat. No. 6,230,410 (depicted as
A further improvement in the art is directed to a linoleum trimming tool. Specifically, Fortin U.S. Pat. No. 5,189,795 (depicted as
As disclosed, the Fortin tool is primarily designed for easily trimming and making cuts in linoleum at points of intersection at a wall during installation. The Fortin tool is an elaborate device including a series of adjustments and a cutting edge with the singular purpose of cutting linoleum.
Recognizing the inherent flaw in providing a device with the single purpose of cutting linoleum, Fortin obtained an independent second patent for a flexible wall trimming device. Specifically, Fortin U.S. Pat. No. 5,450,672 is directed to a second flexible material wall trimming tool designed for trimming flexible or soft flooring materials and wall covering cove materials at the intersection of a floor and wall. As disclosed, the Fortin device “is adapted for cutting soft residential linoleum and sheet vinyl floor coverings, glue down carpets and other soft carpet materials including carpets with rubber or vinyl backing and carpet tiles, and wall covering materials such as vinyl or rubber cove material covering the baseboard area of a wall. The manual trimmer “is adjustable to provide the desired tightness of fit and to match a flexible floor covering and wall cove covering with a desired trim fit at the floor/wall intersection.”
While Fortin, like the aforementioned disclosures, attempted to improve the cutting tools common in the art for cutting flexible flooring at the intersection of a wall, Fortin failed to provide an improved tool for addressing various additional aspects related to the installation of flexible flooring. Specifically, Fortin's inventions and the other aforementioned inventions, fail to provide any means to assist, in the installation of flash coving common in many installations.
While the aforementioned inventions are directed to improved cutting devices, other disclosures in the art are directed to other aspects of flexible flooring installation. For example, systems for improved seam sealing and heat welding are known in the art. Additional disclosures are directed to the installation of custom insets in flexible flooring. Further inventions in the art are directed to guide tools for making precisions cuts. One of these disclosures includes Terhorst U.S. Pat. No. 5,485,676 entitled Carpet Cutting Knife Guide.

While the aforementioned inventions are directed to various improvements in the art for installing flexible flooring, each invention fails to provide an improved system and method for installing flash coving and creating precision flash coving seams. In contrast to the aforementioned disclosures, Stanbery et al. U.S. Pat. No. 4,549,351 addresses an improved apparatus directed to assisting an installer with a flash coving installation. Specifically, Stanbery et al. (depicted as
Recognizing the failure of an improved apparatus and method for installing flash coving in flexible flooring installations, the present disclosure is directed to assist an installer create flash coving in flexible flooring installation.
SUMMARY OF THE INVENTIONIn view of the foregoing disadvantages inherent in the known and various flexible flooring installation systems and devices now disclosed in the prior art, in accordance with a first preferred embodiment of the present invention, provided is a flash coving installation guide device for aiding an installer to make proper flash coving cuts and seams. More specifically, the first preferred embodiment is designed to be utilized to control and ultimately eliminate extensive damage to products and injuries to installers common with creating flash coving in flooring devices.
The primary purpose of the present invention, which will be described subsequently in greater detail, is to provide a first preferred embodiment concerning a guide tool for concise and proper cuts in flexible flooring to allow for the creation of proper seams in flash coving. The present invention is directed to a trim corner guide manufactured in a first right hand trim corner guide and a second left hand trim corner device. The devices are manufactured of sufficient material to act as a guide for a utility knife while cutting flexible flooring and are of sufficient thickness to allow the knife to extend beyond the guide.
The hand-operated left hand trim corner guide is manufactured from a single piece of sturdy plastic material and is composed of a lower base having an upper surface and an underside adapted for contact with a flooring surface integrated with a curved cove forming portion angled to form an approximate ninety degree angle adapted to press the flooring surface into the subfloor and wall at or about an inside or outside corner. Due to inconsistencies in construction, in the preferred embodiment, this angle is increased to roughly ninety-five degrees as to allow the user to apply sufficient pressure to bend the guide to the approximate wall/floor angle and securely hold guide in place. The curved cove forming portion is further integrated with an upper portion of sufficient height to press flooring material against wall. Further integrated with the guide are guide post members allowing the installer to hold the guide in place and apply pressure to guide as to minimize movement of the guide during the cutting process. The left portion of guide is generally manufactured as a straight-edge while the right miter edge portion of guide is manufactured at a forty-five degree angle to allow for an angled miter cut at intersection of flooring material so as to create an aligned seam when installing flash coving.
The right hand trim corner guide is manufactured of generally mirrored-image dimensions so as to mate with left hand trim corner guide. Specifically, The right portion of right hand trim corner guide is generally manufactured as a straight-edge while the left miter edge portion of right hand trim corner guide is manufactured at a forty-five degree angle to allow for an angled miter cut at intersection of flooring material so as to create an aligned seam when installing flash coving. Thus, when left hand trim corner guide and right hand trim corner guide are aligned at respective miter edge portion, the two guides mate to form an outside ninety degree corner.

Moreover, well known methods, procedures, and substances for both carrying out the objectives of the present invention and illustrating the preferred embodiment are incorporated herein but have not been described in detail as not to unnecessarily obscure novel aspects of the present invention.
The method for installing sheet flooring flash coving is complex and highly dependent on the skill of the craftsman as much of the installation requires free-hand forming of the material. Specifically, a craftsman must free hand many of the cuts that are ultimately fused to create seams that must be relatively hidden after they are joined resulting in a “seamless” presentation.
While flash coving may be installed by various craftsmen in generally different manners, the most common system for installing flash coved sheet flooring recommended by Armstrong World Industries, Inc. is expressed herein in reference to the use of the present invention. (See Armstrong, Guaranteed Installation Systems 2006/2007; AWI, 2006). However, while various craftsmen may install the flooring in different manners and rely on individual expertise, it will be evident to those of ordinary skill in the art that the present invention may be utilized for all methods of flash coving installation known in the art as well as modified methods of the future.
Thus, in order to install flash coving, the floor must be properly prepared and the cap strip and cove stick must be installed. With these installations in place, the scribing felt pattern can be set. Particularly, the craftsmen must cut in the scribing felt or guide paper to the edges of the cove stick. Once cut, the edges of the scribing felt are butted together and secured to the floor.
At this point of installation it is recommended that two templates are created from either scrap material or other similar material. The first template is created in a “T” structure, exhibiting approximately eight inches in height and six inches in width on the upper portion of the “T” and two inches in width on the base portion of the “T”. The second template, created from the same material, is in a triangular form with legs of four inches. At the right angle of the triangle, a protruding portion of one and one half inch radius for the cove base is formed. To form this second template, the craftsman must first draw a four inch square on the scrap material and connect two opposing corners with a diagonal line. At one corner, extend the diagonal line one inch beyond the corner. To mark the point on the template, set the dividers using the same radius as the cove stick and swing arcs touching the edge of the square piece and the diagonal intersecting line. This point of the template will allow the user to mark the inside corners. While this is likely the most common dimensions for each template, modification to size may be apparent depending on the desired height of the cove stick and other installation factors.
With the templates created, the first template is placed in the inside corner and under the cap strip. Pressed firmly into the cove stick, the craftsman utilizes the template to trace around the portion of the template interacting with the felt paper. This step is repeated on the alternate side of the inside corner. It is further recommended that when marking the inside corners, an allowance is made for one piece of material fitting against the other by inserting a scrap piece between the wall and the template. In addition, it is typical in the art to make the allowance on the side of the inside corner that is fitted last. Continuing with the first template, the craftsman marks at various distances the height of the cap strip at several places along the wall.
An overhang is provided on the side opposite where the fill piece will be fit. Along the wall where the fill piece will be placed, a straightedge line is placed on the felt paper a predetermined distance from the wall in a direction parallel to the wall. A second line is drawn by the craftsman extending at a forty-five degree angle from the outside corner miter of the cove stick. With all lines scribed onto the scribing felt, crosslines are etched at the seams for reference.
With the pattern complete, the lines are transferred from the scribing felt onto the material, where necessary the angle marks and other marks are connected with a straightedge, the forty-five degree angle cut is extended approximately three inches, and the flooring material is prepared for cutting. Since the cutting stage requires the most skill in, the field, the scribe marks must be relatively accurate to provide for a “seamless” installation. In certain portions, stop cuts, parallel to the scribes, to prevent material tearing and safety cuts to prevent the knife from sliding and injuring the craftsmen are created. Portions are also taped at stress points to further prevent tears.
Once cut, spread adhesive is applied on the floor to act as a securing means to integrate flooring material with floor. Once the cut flooring material is placed in the room, certain portions are seated and the flooring material is placed gently into the corners. After the seating the flooring material and tucking the corners, flooring material is inserted under the cap strip staring at the center portions of the walls. To assist in the installation under the cap strip, a heating gun may be utilized to alter the pliability of the flooring material and prevent damage to the flooring material. To secure the Material in place, the flooring material is also seated utilizing a roller.
The next step in anchoring flash coved sheet flooring material, and most relevant step to the use of the present invention, is the formation and installation of the mitered outside corner. Finishing the outside corner is typically completed roughly by hand by each craftsman and the quality of each corner seam is highly dependent on the skill of the installer. Further, damage at the outside corner may result in substantial repair time and material costs to mend or reconstruct the portion of damaged material.
The first step for constructing and finishing a mitered outside corner requires a craftsman to position a recess scriber at an outside corner to mark the section extending beyond the corner. To avoid damage to the material, a protective piece of scrap material is utilized as a guide for the knob of the scriber to ride against the wall. This use of scrap material also provides for an allowance for the fill piece to miter to the portion being marked. The second step requires a craftsman to create a second scribe at the vertical section to the top of the cove stick.
Again, utilizing the first template previously prepared, the third step in finishing the corner requires a craftsman to position the template along the forty-five degree line on the flooring material and curve the template upwards along the radius of the cove stick to the vertical scribe line and etch a guide line along the edge of the template. According to the fourth step, positioning a knife at a forty-five degree angle to the corner, a craftsman free hands a cut from the top vertical scribe to along the miter of the cove stick to the bottom portion of the cove stick. Remove the scrap material created from the cutting area without cutting the portion in contact with the floor as this portion, with the fill piece in position, will be double cut to provide a proper seam.
The aforementioned fill piece created in an “L” shape as step five is created by an installer utilizing free hand cuts. With the fill piece formed and heated, it can be positioned within the material void to allow the craftsman to utilize the recess scribe set for an outside scribe to scribe the vertical section from the top of the cove stick.
Again, positioning the first template along the forty-five degree line on the flooring material, the seventh step of installation, requires the craftsman to scribe the vertical portion of the fill piece up the radius of the cove stick until the scribe intersects the bottom of the scribe line previously created. Next (the eight step of installation), positioning a free hand knife at a forty-five degree angle to the corner, the craftsman cuts downwards from the top of the scribe line along the miter near the cove stick. Again the scrap is removed from the location without cutting the portion closest to the floor as this portion will serve as the upper material of the aforementioned double cut.
The ninth step of installation requires the removal of the fill piece and the application of adhesive material thereto. The fill piece is subsequently heated, placed within the void portion, and rolled into place. The aforementioned double cut through the first layer of flooring material from the bottom of the cove stick to the edge of the fill piece (tenth step).
The eleventh and final step of installation requires the craftsman to burnish the miter on the wall and around the cove stick cut. Fine sandpaper may be utilized on the outside corners of the miter to remove any burrs caused by the recess scriber.
From the aforementioned eleven step process, it is apparent that the installation of sheet flooring requires a high level of specific skill for numerous reason. First, a craftsman must apply specific knife angles to provide elaborate cuts and resulting “hidden” seams. Further, a craftsman must create specific field cuts on templates created from scrap material that must include accurate and precise angles. In addition, a craftsman must be skilled with a recess scribe and other specific tools to create accurate cuts and guides. It is apparent that improper use of these tools may result in damage to flooring material secured in place and ultimately in excessive repairs to installed materials. Finally, as each of the aforementioned cuts are performed free hand by the craftsman, it is readily apparent to those of skill in the art that without any protection devices, any intended movement of the knife during a cut could result in excessive injury to the craftsman.
It is readily apparent that there exists a need in art to provide a singular tool or guide apparatus which allows a user to avoid the excessive field free hand cuts. Thus, presented is a guide apparatus for assisting a craftsman perform the aforementioned cuts in forming the miter corners required for the installation of flash coving in sheet flooring applications as defined in the steps one through eleven, supra.
