Definitions
- the present invention relates generally to the field of wall to wall carpeting techniques, and more particularly to floor covering transition device for use between a section of carpet and another floor covering.
- Carpet installation and replacement in dwellings, such as homes and apartment units can be a very expensive proposition. This is primarily due to the fact that adjoining pieces of carpet within a room or between rooms must match. In other words, all the pieces of carpet must come from the same dye lot. Otherwise, a person will be able to visually detect that the pieces of carpet do not match. This problem drastically increases the cost of carpet replacement because all the carpet has to be replaced rather than only those pieces or rooms that need new carpet.
- One attempt to solve this problem has been the replacement of a section of carpet with a wood floor looking laminate product (or sheet vinyl). For example, the carpet in a hallway is replaced with the wood floor looking laminate product. As a result, the carpet in the rooms adjoining the hallway, such as bedrooms, does not have to match each other.
- the biggest drawback of this type of installation is that it is substantially more expensive than a conventional installation. Moreover, this approach also does not allow the possibility of installing carpet in a living room and dining room independent of one another.
- the present invention provides a transition device that can be installed between two pieces of flooring material or floor covering to separate areas, such as rooms, closets and hallways, in a typical dwelling.
- the present invention is particularly applicable for use in apartment units to provide eye-appealing, fashionable accents to the finished appearance of the apartment unit.
- different dye-lots and even different colors can be combined in the same unit, a practice that has previously been impractical.
- the ability to mix colors, dye-lots and new carpet with old carpet allows the installer to use a much lower priced segment of the carpet mills inventory stock known as “short-rolls” or remnants. Typically, this carpet was difficult for the mills to get rid of and is priced at less than half the normal cost of full rolls of carpet.
- the finished initial installation also gives the management companies the option of replacing partial units or isolated rooms or areas in an apartment unit.
- This has been impractical previous to the development of the present invention due to the fact that carpeting is manufactured in dye lot increments and generally carpets that come from different dye lots cannot be combined. Consequently, if a single room needs to be replaced in a unit, normally replacement of the carpet within the entire unit is ordered so that all the carpet will match.
- management companies are able to save money and time as compared to a conventional carpet installation. This is possible due to the fact that the present invention allows the use of short rolls and remnants for these installations, which can be bought at significant discounts from standard carpet at full-roll pricing.
- the transition devices of the present invention provide a new visual appearance for apartment units in a business where there is very little opportunity to differentiate product, namely the unoccupied apartment unit that is being marketed.
- the apartment units all look very much the same, especially when it comes to the flooring products.
- the present invention provides a transition device assembly that includes an elongated T-shaped member, a covering and an elongated base that have a combined height to provide a transition between a first floor covering and a second floor covering.
- the elongated T-shaped member has an upper portion and a base portion.
- the covering is attached to the elongated T-shaped member and covers a top and each side of the upper portion of the T-shaped member.
- the elongated base has a substantially flat portion and a longitudinally extending upwardly opening channel for receiving the base portion of the elongated T-shaped member. In one case, there is also a notch in each end of the covering and the elongated T-shaped member to accommodate a doorstop.
- the covering also extends beyond the ends of the elongated T-shaped member and has a notch in each end of the extended covering to accommodate a doorstop. In another case, there are no notches and the bottom of the doorstop is removed as part of the installation.
- the present invention provides a system for transitioning between a first floor covering and a second floor covering that includes an elongated T-shaped member, a covering and an elongated base.

- FIG. 1A illustrates a transition 100 between two floor coverings 102 (first floor covering) and 104 (second floor covering) in a doorway in accordance with the prior art.
- the doorway includes a doorframe 114 , which has a doorstop 122 , located between walls 110 and 112 .
- Molding 116 is installed at the base of wall 110 and 112 around the perimeter of the rooms. Carpet in the different rooms and hallways, such as 102 and 104 are seamed together with hot seaming tape 106 .
- the glue on the tape 106 is activated by an electric seaming iron, which is run across the tape 106 .
- Both pieces of carpet 102 and 104 are set together across the seaming tape 106 , pushed together tightly and left to bond as the glue hardens (as it cools).
- the carpet 102 and 104 in the rooms is secured to the floor by stretching it over tack strips 108 , which are installed around the perimeter of the rooms.
- the tack strips 108 are typically strips of wood or synthetic material about 1 ⁇ 4 inch thick, 1 inch wide and 3 feet long that have metal pins embedded in them. The pins stick up out of the wood about 1 ⁇ 8 of an inch and hold the carpet in place after the carpet is stretched over it. Tackless strips may also be used.
- Seaming the two pieces of carpet together 102 and 104 is a labor intensive and “tricky” proposition. More specifically, two pieces of carpet 102 and 104 are seamed together by overlapping the edges of the carpet 102 and 104 leaving about 2 inches of excess carpet at the middle of the doorway. A chalk line is then snapped on the back of the overlapped carpet edges and a straight edge is trimmed to ensure a straight seam. The straight edges are overlapped and a row cutter is used to cut the bottom piece. The edge of the top piece is used as a guide in cutting the seam to fit. A length of seaming tape 106 is cut and centered under the seam. The adhesive side of the tape 106 must be facing up and the carpet seams must butt up against each other. A seaming iron is then used to melt the adhesive by slowly pulling the iron down the tape 106 . Once the adhesive is melted, the carpet edges are immediately pressed together over the tape 106 . The seam should then be rolled over with a seam rolling tool.
- FIG. 1B a cross sectional view of FIG. 1A is shown.
- First floor covering 102 and second floor covering 104 both of which are carpet in this example, are installed on padding 118 , which is placed on top of the floor 120 .
- the seam or transition 100 is located between the doorframes 114 and is created, as described above, using seaming tape 106 .
- a transition device 200 between two floor coverings 202 (first floor covering) and 204 (second floor covering) in a doorway in accordance with the present invention is shown.
- the first and second floor coverings can be the same type (e.g., new versus old, different dye lots, etc.) or different types (e.g., carpet, tile, wood, vinyl, laminate, etc.).
- the doorway includes a doorframe 114 , which has a doorstop 122 , located between walls 110 and 112 . Molding 116 is installed at the base of wall 110 and 112 around the perimeter of the rooms.
- the carpet 202 and 204 in the rooms is secured to the floor by stretching it over tack strips 108 , which are installed around the perimeter of the rooms.
- the tack strips 108 are typically strips of wood or synthetic material about 1 ⁇ 4 inch thick, 1 inch wide and 3 feet long that have metal pins embedded in them. The pins stick up out of the wood about 1 ⁇ 8 of an inch and hold the carpet in place after the carpet is stretched over it. Tackless strips may also be used.
- the edges of carpet 202 and 204 are pushed between the wall and the tack strips 108 and the transition device 200 and the tack strips 108 .
- Transition devices 200 which may be simulated wood-plank insert pieces, are glued down throughout the entire unit after the old carpet is removed. Note that the transition devices 200 may also be used in new installations. The normal locations for the transition devices 200 are usually identical to those where regular seams go in a conventional installation. That would usually include all standard doors leading from one carpeted area to another and other strategic spots that create practical separation of carpets. These spots would include the beginning of a hallway leading to bedrooms and a prominent transition piece between the living room and dining room whenever possible. Note that the transition devices 200 can be used with other floor coverings, such as tile, wood or vinyl.
- FIG. 2B a cross sectional view of FIG. 2A is shown.

- the covering 312 , 332 and 352 is preferably at least 1/16 inch thick to provide durability. In the case of transition device 320 , the covering 332 should extend at least 1 ⁇ 2 inch underneath the elongated core 322 .
- the covering 312 , 332 and 352 can be made from the same durable sheet vinyl that typically goes into the kitchens and bathrooms of many standard apartment units.
- the wood plank styles of the sheet vinyl look surprisingly like real wood plank.
- the transition devices 300 , 320 and 340 that are to be used in doorways can be cut to the exact width of the door casings (universal standard sizes most often found are 24, 30 and 32 inches).
- the short side dimension of these transition devices 300 , 320 and 340 is usually 5 inches.
- the transition devices 300 , 320 and 340 that are used to separate living rooms from dining rooms usually have short side dimensions of 7 inches and are specially manufactured to whatever lengths are required. Special alterations can be easily made on site, as the material is easily cut with a small hand held saw.
- the present invention allows installers to be issued the correct amount of the pre-manufactured transition devices 300 , 320 and 340 when they pick up the carpet for the installation.
- Large inventories of the most common sized transition devices 300 , 320 and 340 can be maintained at the carpet warehouse. For example, there are three common door sizes that occur more often than any others.

- the strips 402 are then nailed to the floor 404 around the perimeter of the room using masonry nails 406 or other fastening device.
- the strips 402 should be spaced away from the wall and the transition device 400 by approximately 2 ⁇ 3 of the thickness of the carpet.
- the strips 402 should join together at the comers and the pointed pins 408 in each strip should face the wall or transition device 400 .
- the padding 410 and 412 are then cut to fit the rooms, attached to the floor 404 and trimmed so that the padding abuts or is in close proximity to the strips 402 .
- the carpet 414 is then cut and laid on top of the padding 410 .
- carpet 416 is then cut and laid on top of the padding 412 .
- the carpet 414 and 416 are then systematically hooked to the strips 402 and stretched until the edge of the carpet 414 and 416 is attached to the all the strips 402 around the room.

Description
- This application is a continuation-in-part of and claims priority based on U.S. patent application Ser. No. 10/684,984 filed Oct. 14, 2003, which is a continuation of and claims priority to U.S. patent application Ser. No. 10/202,231 filed Jul. 24, 2002 that issued as U.S. Pat. No. 6,662,518 B1 on Dec. 16, 2003, all of which are incorporated herein by reference.
- The present invention relates generally to the field of wall to wall carpeting techniques, and more particularly to floor covering transition device for use between a section of carpet and another floor covering.
- Carpet installation and replacement in dwellings, such as homes and apartment units can be a very expensive proposition. This is primarily due to the fact that adjoining pieces of carpet within a room or between rooms must match. In other words, all the pieces of carpet must come from the same dye lot. Otherwise, a person will be able to visually detect that the pieces of carpet do not match. This problem drastically increases the cost of carpet replacement because all the carpet has to be replaced rather than only those pieces or rooms that need new carpet. One attempt to solve this problem has been the replacement of a section of carpet with a wood floor looking laminate product (or sheet vinyl). For example, the carpet in a hallway is replaced with the wood floor looking laminate product. As a result, the carpet in the rooms adjoining the hallway, such as bedrooms, does not have to match each other. The biggest drawback of this type of installation is that it is substantially more expensive than a conventional installation. Moreover, this approach also does not allow the possibility of installing carpet in a living room and dining room independent of one another.
- There is, therefore, a need for a transition device that can be installed between two floor coverings to separate areas and allows the use of different carpet dye lots or the installation of new carpet next to old carpet.
- The present invention provides a transition device that can be installed between two pieces of flooring material or floor covering to separate areas, such as rooms, closets and hallways, in a typical dwelling. The present invention is particularly applicable for use in apartment units to provide eye-appealing, fashionable accents to the finished appearance of the apartment unit. By separating the different rooms and isolatable floor areas, different dye-lots and even different colors can be combined in the same unit, a practice that has previously been impractical. The ability to mix colors, dye-lots and new carpet with old carpet allows the installer to use a much lower priced segment of the carpet mills inventory stock known as “short-rolls” or remnants. Typically, this carpet was difficult for the mills to get rid of and is priced at less than half the normal cost of full rolls of carpet.
- The finished initial installation also gives the management companies the option of replacing partial units or isolated rooms or areas in an apartment unit. This has been impractical previous to the development of the present invention due to the fact that carpeting is manufactured in dye lot increments and generally carpets that come from different dye lots cannot be combined. Consequently, if a single room needs to be replaced in a unit, normally replacement of the carpet within the entire unit is ordered so that all the carpet will match. As a result, management companies are able to save money and time as compared to a conventional carpet installation. This is possible due to the fact that the present invention allows the use of short rolls and remnants for these installations, which can be bought at significant discounts from standard carpet at full-roll pricing. Even if short rolls and/or remnants are not used, the savings of doing only part of a unit, versus a complete unit are significant. Moreover, the transition devices of the present invention provide a new visual appearance for apartment units in a business where there is very little opportunity to differentiate product, namely the unoccupied apartment unit that is being marketed. The apartment units all look very much the same, especially when it comes to the flooring products.
- More specifically, the present invention provides a transition device assembly that includes an elongated T-shaped member, a covering and an elongated base that have a combined height to provide a transition between a first floor covering and a second floor covering. The elongated T-shaped member has an upper portion and a base portion. The covering is attached to the elongated T-shaped member and covers a top and each side of the upper portion of the T-shaped member. The elongated base has a substantially flat portion and a longitudinally extending upwardly opening channel for receiving the base portion of the elongated T-shaped member. In one case, there is also a notch in each end of the covering and the elongated T-shaped member to accommodate a doorstop. In another case, the covering also extends beyond the ends of the elongated T-shaped member and has a notch in each end of the extended covering to accommodate a doorstop. In another case, there are no notches and the bottom of the doorstop is removed as part of the installation.
- In addition, the present invention provides a system for transitioning between a first floor covering and a second floor covering that includes an elongated T-shaped member, a covering and an elongated base. The elongated T-shaped member has an upper portion and a base portion. The covering is attached to the elongated T-shaped member and covers a top and each side of the upper portion of the T-shaped member. The elongated base is attached to a floor having a substantially flat portion and a longitudinally extending upwardly opening channel for receiving the base portion of the elongated T-shaped member. The first floor covering is attached to the floor and extends underneath one side of the upper portion of the elongated T-shaped member. The second floor covering is attached to the floor and extends underneath the other side of the upper portion of the elongated T-shaped member. The elongated base, elongated T-shaped member and the covering have a combined height to provide a transition between the first floor covering and the second floor covering. In one case, there is also a notch in each end of the covering and the elongated T-shaped member to accommodate a doorstop. In another case, the covering also extends beyond the ends of the elongated T-shaped member and has a notch in each end of the extended covering to accommodate a doorstop. In another case, there are no notches and the bottom of the doorstop is removed as part of the installation.
- Moreover, the present invention provides a method for manufacturing a device for transitioning between a first floor covering and a second floor covering. An elongated T-shaped member having an upper portion and a base portion is fabricated and a covering is attached to the elongated T-shaped member such that the covering covers a top and each side of the upper portion of the T-shaped member. An elongated base is also fabricated and has a substantially flat portion and a longitudinally extending upwardly opening channel for receiving the base portion of the elongated T-shaped member. The elongated base, elongated T-shaped member and the covering have a combined height to provide a transition between a first floor covering and a second floor covering. In one case, a notch is also cut in each end of the covering and the elongated T-shaped member to accommodate a doorstop. In another case, the covering also extends beyond the ends of the elongated T-shaped member and a notch is cut in each end of the extended covering to accommodate a doorstop.
- In addition, the present invention provides a transition device assembly that includes an elongated T-shaped semi-flexible member and two or more bases. The elongated T-shaped semi-flexible member has an upper portion and a base portion. The two or more bases have a substantially flat portion and an upwardly extending opening channel for receiving the base portion of the elongated T-shaped member. The two or more bases and elongated T-shaped semi-flexible member provide a transition between a non-linear first floor covering and a corresponding second floor covering.

The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not limit the scope of the invention.
- The present invention provides a transition device that can be installed between two pieces of flooring material or floor covering to separate areas, such as rooms, closets and hallways, in a typical dwelling. The present invention is particularly applicable for use in apartment units to provide eye-appealing, fashionable accents to the finished appearance of the apartment unit. By separating the different rooms and isolatable floor areas, different dye-lots and even different colors can be combined in the same unit, a practice that has never been viewed favorably by apartment owners or managers previously. The ability to mix colors and dye-lots allows the installer to use a much lower priced segment of the carpet mills inventory stock known as “short-rolls” or remnants. Typically, this carpet was difficult for the mills to get rid of and is priced at less than half the normal cost of full rolls of carpet.
- The finished initial installation also gives the management companies the option of replacing partial units or isolated rooms or areas in an apartment unit. This has been impractical previous to the development of the present invention due to the fact that carpeting is manufactured in dye lot increments and generally carpets that come from different dye lots cannot be combined.

- For example,
FIG. 1A illustrates atransition 100 between two floor coverings 102 (first floor covering) and 104 (second floor covering) in a doorway in accordance with the prior art. The doorway includes adoorframe 114, which has adoorstop 122, located betweenwalls wall hot seaming tape 106. The glue on thetape 106 is activated by an electric seaming iron, which is run across thetape 106. Both pieces ofcarpet tape 106, pushed together tightly and left to bond as the glue hardens (as it cools). Thecarpet - Seaming the two pieces of carpet together 102 and 104 is a labor intensive and “tricky” proposition. More specifically, two pieces of
carpet carpet tape 106 is cut and centered under the seam. The adhesive side of thetape 106 must be facing up and the carpet seams must butt up against each other. A seaming iron is then used to melt the adhesive by slowly pulling the iron down thetape 106. Once the adhesive is melted, the carpet edges are immediately pressed together over thetape 106. The seam should then be rolled over with a seam rolling tool. - Now referring to
FIG. 1B , a cross sectional view ofFIG. 1A is shown. First floor covering 102 and second floor covering 104, both of which are carpet in this example, are installed onpadding 118, which is placed on top of thefloor 120. The seam ortransition 100 is located between thedoorframes 114 and is created, as described above, using seamingtape 106. - Referring now to the present invention as illustrated in
FIG. 2A , atransition device 200 between two floor coverings 202 (first floor covering) and 204 (second floor covering) in a doorway in accordance with the present invention is shown. As previously discussed, the first and second floor coverings can be the same type (e.g., new versus old, different dye lots, etc.) or different types (e.g., carpet, tile, wood, vinyl, laminate, etc.). The doorway includes adoorframe 114, which has adoorstop 122, located betweenwalls wall carpet carpet transition device 200 and the tack strips 108. -
Transition devices 200, which may be simulated wood-plank insert pieces, are glued down throughout the entire unit after the old carpet is removed. Note that thetransition devices 200 may also be used in new installations. The normal locations for thetransition devices 200 are usually identical to those where regular seams go in a conventional installation. That would usually include all standard doors leading from one carpeted area to another and other strategic spots that create practical separation of carpets. These spots would include the beginning of a hallway leading to bedrooms and a prominent transition piece between the living room and dining room whenever possible. Note that thetransition devices 200 can be used with other floor coverings, such as tile, wood or vinyl. - Now referring to
FIG. 2B , a cross sectional view ofFIG. 2A is shown.Carpet 202 or the first floor covering is installed onpadding 206 andcarpet 204 or the second floor covering is installed onpadding 208, both of which are placed on top of thefloor 120. Thetransition device 200 is located between thedoorframes 114 and between tack strips 108 a and 108 b.
