In this respect, the transitional flooring surface is necessary to prevent the possibility of an individual from tripping as they walk between the two flooring materials and to provide a gradual ascent or decent for wheeled apparatus moving between the two flooring materials.
With regard to individuals walking or running bet<veen two flooring materials having different heights, there is a possibility that as the individual crosses from the lower flooring material to the higher flooring material that they may trip over the higher flooring material, and consequently injure themselves.
2~ It is also possible that as the individual crosses between the two flooring materials that they may lose their balance due to the sudden rise or fall in the height of the flooring material. This may also lead to injury.
Where a wheeled apparatus is rolled between two flooring materials having different heights, the wheeled apparatus may become jarred due to a bump created by the differing heights of the flooring materials. In this respect, the wheeled apparatus may encounter a sudden decent as it moves from the higher flooring material to the lower flooring material, or may encounter a sudden ascent as it moves from the lower flooring material to the higher flooring material.
Another problem encountered when moving from a lower flooring material to a higher flooring material is that the higher flooring material may act as an impediment to movement of the wheeled apparatus between the flooring S materials. In this regard, it may be necessary to apply an additional force to the wheeled apparatus or lift up the wheeled apparatus onto the higher flooring material.
With respect to pedestrians walking or running between two flooring materials of differing heights, the transitional flooring surface provided by a flooring adapter device can reduce or eliminate any obstacle created by the higher flooring material, and provide a more gradual change in heights between the two flooring materials.
In a situation where an apparatus having wheels is moved between two flooring materials of differing heights, the transitional flooring surface provided by a flooring adapter device reduces or eliminates jarring to the wheeled apparatus as it moves between the two flooring materials and eliminates any impediment caused by a higher flooring material.
In the case of a health care facility, a . g . , a hospital, it is common today to find hallways having carpeting, and operating and treatment rooms having vinyl or rubber flooring (e.g., tile). A flooring adapter device providing a transition surface between the carpeting and vinyl or rubber flooring is necessary to prevent injury to individuals walking or running between the flooring materials of differing heights, and to prevent jarring individuals riding in wheelchairs or gurneys that are moved between the flooring materials. In the case of wheelchairs and gurneys, it should be appreciated that jarring or sharp bumps occurring as the wheelchairs or gurneys are moved across two different flooring materials may cause harm or discomfort to a patient who has just received surgery.
The transitional flooring surface provided by prior art flooring adapter devices have steep slopes. These steep slopes create a disruption in the flooring surface which does not adequately prevent injury (e.g., tripping or falling) to pedestrians walking or running, and which does not adequately prevent jarring and bumping to wheeled apparatus, a . g . , wheelchairs and gurneys.

Referring now to the drawings, wherein the showing is for the purpose of illustrating preferred embodiments of the present invention only, and not for the purpose of limiting same, FIG. 1 shows a flooring adapter device 10 according to a first preferred embodiment of the present invention. In the embodiment sho~avn, flooring adapter device 10 is an elongated, substantially flat sheet made of an extruded vinyl or rubber material. Preferably, flooring adapter device 10 is made of PVC (polyvinyl chloride).
Flooring adapter device 10 is generally comprised of an upper surface 20 and a lower surface 30. Lower surface 30 is comprised of a base portion 32, and a pair of L-shaped shoulders 40 and 60. Base portion 32 has a generally planar surface so as to engage flatly against (i.e., parallel to) the floor surface, when flooring adapter device 10 is in use.
First L-shaped shoulder 40 is comprised of a first vertical section 42 and a first horizontal section 44. First vertical section 42 is generally perpendicular to first horizontal section 44. However, it will be appreciated that since it is easier to form a radius (rather than sharp corners) using a die, a curved surface may be formed between first vertical section 42 and first horizontal section 44. A
first cavity 46, dimensioned to receive a first flooring material, is defined by first vertical section 42 and first horizontal section 44. In a preferred embodiment of the present invention, first cavity 46 is dimensioned to receive a vinyl or rubber flooring material (e.g., tile) having a height of 1/8-inch. However, it should be appreciated that cavity 46 may also be dimensioned to receive other types of flooring materials, including linoleum.
Second L-shaped shoulder 60 is comprised of a second vertical section 62 and a second horizontal section 64. Second vertical section 62 is generally perpendicular to first horizontal section 64. As with the case of first vertical section 42 and first horizontal section 44, a curved surface may be formed between second vertical section 62 and second horizontal section 64 (as shown in FIG.
2), since it is easier to use a die to form a radius than sharp corners. Second vertical section 62 and second horizontal section 64 define a second cavity 66, which is dimensioned to receive a second flooring material having a second height. In a preferred embodiment, second cavity 66 is dimensioned to receive carpeting having a height of 1/4-inch. However, it will be appreciated that cavity 66 may also be dimensioned to receive carpet of other heights, as well as other types of flooring materials, including ceramic, rubber and vinyl tile and linoleum.
Upper surface 20 is comprised of a central portion 22, first end portion 24 and second end portion 26. Central portion 22 has a generally flat planar surface, CA 02223223 1997-11-28 , which is sloped relative to base portion 32. In this respect, central portion 22 is at an angle Y of approximately 3°-5° relative to base portion 32 (see FIG. 2). In a preferred embodiment of the present invention, central portion 22 is sloped upward from first end portion 24 towards second end portion 26.
S First end portion 24 has a generally vertical surface extending between central portion 22 and first horizontal section 44 of first L-shaped shoulder 40.
Second end portion 26 has a convexly rounded surface extending between central portion 22 and second horizontal section 64 of second L-shaped shoulder 60.
The surface of second end portion 26 curves downward from central portion 22 towards second horizontal section 64.
The length of flooring adapter device 10 may vary. In this regard, flooring adapter device 10 may be provided in sheet sections of varying length, or, since extruded vinyl and rubber are somewhat flexible, in very long lengths in a roll.
Preferably, flooring adapter device 10 is provided in 6-feet or 12-feet sheet sections. These lengths are most suitable for installation in hallways and doorways where transitions between different flooring materials are most common. It will be appreciated that the sheet sections may be cut to the appropriate lengths required in a particular application.
The preferred dimensions of flooring adapter device 10 will now be described with reference to FIG. 2. It will be appreciated that following dimensions for flooring adapter device 10, are preferred where flooring adapter device 10 provides a transition between carpeting and a resilient flooring material (e.g., vinyl or rubber tile). With respect to lower surface 30, base portion 32 has a preferred width dimension D of approximately 1.75 inches. First vertical section 42 has a preferred height dimension of approximately 0.125 inches, while second vertical section 62 has a preferred height dimension of 0.375 inches. First horizontal section 44 and second horizontal section 64 each have a preferred width dimension of approximately 0.375 inches. With respect to upper surface 20, first end portion 24 has a preferred height dimension E of approximately 0.032 inches.
Second end portion 26 has a preferred vertical height dimension F of 0.125 inches (as measured from second horizontal section 64 to central portion 22). Central portion 22 has a width dimension A of approximately 2.375 inches, and a width _' dimension B of approximately 2.375 inches. The width dimension C of upper surface 20 is approximately 2.5 inches. Given the foregoing preferred dimensions, central portion 22 vertically rises approximately 0.343 inches from first end portion 24 to second end portion 26. The ratio of width dimension D of base portion 32 to width dimension C of upper surface 20 is approximately 0.7.
In the case where flooring adapter device 10 is providing a transition between thicker carpeting and a resilient flooring material, or a ceramic flooring material (e.g., ceramic tile) and a resilient flooring material, the dimensions defining L-shaped shoulders 40 and 60 may be modified.
The flooring adapter device 10 described above is utilized in the following manner. In a preferred method of installation, the two flooring materials (e.g., carpeting and vinyl or rubber tile, or ceramic flooring material and vinyl or rubber tile) are applied to the appropriate floor surface. In the case of carpeting, carpet padding may also be placed under the carpeting. Next, a section of flooring adapter device 10 of appropriate length is selected, or alternatively cut to size.
Flooring adapter device 10 is then secured to the floor surface, between the two flooring materials, preferably with the use of an adhesive (e.g., liquid adhesive for vinyl or rubber flooring products or double-sided adhesive tape) or other similar means. The top of the first flooring material (e.g., vinyl or rubber tile) will be adjacent to first horizontal section 44, while the side edge of the first flooring material will be adjacent to first vertical section 42. Similarly, the top of the second flooring material (e.g., carpeting) will be adjacent to second horizontal section 64, while the side edge of the second flooring material will be adjacent to second vertical section 62. It will be appreciated that both first horizontal section 44 and second horizontal section 64 extend over the top of the respective flooring materials. When installed, base portion 32 of flooring adapter device 10 will be substantially parallel with the floor surface, while central portion 22 will be transverse to the floor surface, thus providing a gradual, sloping surface between the two flooring materials of differing heights. Alternatively, flooring adapter device 10 can be secured to the floor surface before one or both of the flooring materials is applied to the respective floor surface.
It will be appreciated that the preferred embodiment of flooring adapter _g_ device 10, as illustrated in FIGS. 1 and 2, is most suitable for use with 1/8-inch vinyl or rubber tile and 1/4-inch carpet. However, it is contemplated that flooring adapter device 10 may be modified to accommodate flooring materials having varying dimensions. In this respect, the dimensions of cavities 46 and 66, the width of base portion 32 and upper surface 20, and the slope (i.e., angle Y) of central portion 22, may vary to accommodate flooring materials of varying heights.
FIG. 3 shows a flooring adapter device 110 according to a second preferred embodiment of the present invention. In the embodiment shown, flooring adapter device 110 is an elongated, substantially flat sheet made of an extruded vinyl or rubber material. Flooring adapter device 110 is best suited as a transitional flooring surface between carpeting and a concrete floor. Preferably, flooring adapter device 110 is made of PVC (polyvinyl chloride).
Flooring adapter device 110 is generally comprised of an upper surface 120 and a lower surface 130. Lower surface 130 is comprised of a base portion 132, and an L-shaped shoulder 160. Base portion 132 has a generally planar surface so as to engage flatly against (i.e., parallel to) the floor surface, when flooring adapter device 110 is in use.
L-shaped shoulder 160 is comprised of a vertical section 162 and a horizontal section 164. Vertical section 162 is generally perpendicular to horizontal section 164. A curved surface may be formed between vertical section 162 and horizontal section 164, since it is easier to use a die to form a radius than sharp corners. Vertical section 162 and horizontal section 164 define a cavity 166, which is dimensioned to receive a flooring material. In a preferred embodiment, cavity 166 is dimensioned to receive carpeting having a height of approximately 1/4-inch. However, it will be appreciated that cavity 166 may also be dimensioned to receive other types and sizes of flooring materials, including rubber, vinyl and ceramic tile.
Upper surface 120 is comprised of a central portion 122, first end portion 124 and second end portion 126. Central portion 122 has a generally flat planar surface, which is sloped relative to base portion 132. In this respect, central portion 122 is at an angle Z of approximately 1°-S° relative to base portion 132.
In a preferred embodiment of the present invention, central portion 122 is sloped _g_ upward from first end portion 124 towards second end portion 126.
First end portion 124 has a generally vertical surface extending between central portion 122 and base portion 132. Second end portion 126 has a convexly rounded surface extending between central portion 122 and horizontal section of L-shaped shoulder 160. The surface of second end portion 126 curves downward from central portion 122 towards horizontal section 164.
As in the case of flooring adapter 10 described above, the length of flooring adapter device 110 may vary. In this regard, flooring adapter device 110 may be provided in sheet sections of varying length, or, since extruded vinyl and rubber are somewhat flexible, in very long lengths in a roll. Preferably, flooring adapter device 110 is provided in 6-feet or 12-feet sheet sections. It will be appreciated that the sheet sections may be cut to the appropriate lengths required in a particular application.
The preferred dimensions of flooring adapter device 110 will now be described with reference to FIG. 4. It will be appreciated that flooring adapter device 1I0, as shown in FIG. 4, is best suited as a transition between carpeting and a concrete floor. With respect to lower surface 130, width dimension M is preferably 2.5 inches and width dimension N is preferably 0.375 inches. With respect to upper surface 120, first end portion 124 has a preferred height dimension S of approximately 0.03125 inches. Second end portion 126 has a preferred vertical height dimension R of 0.125 inches. The height dimension P
is preferably 0.375 inches.
The flooring adapter device 110 described above is utilized in a manner similar to flooring adapter device 10. In a preferred method of installation, the two flooring materials (e.g., carpeting and concrete) have been arranged to provide a flooring surface. In the case of carpeting, carpet padding may also be placed under the carpeting. Next, a section of flooring adapter device 110 of appropriate length is selected, or alternatively cut to size. Flooring adapter device 110 is then secured to the floor surface, between the two flooring materials, preferably with the use of an adhesive (e.g., liquid adhesive for vinyl or rubber flooring products or double-sided adhesive tape) or other similar means. The first flooring material (e.g., concrete) will be adjacent to first end portion 124.
The top of the second flooring material (e.g., carpeting) will be adjacent to horizontal section 164, while the side edge of the second flooring material will be adjacent to vertical section 162. It will be appreciated that horizontal section 164 extends over the top of the adjacent flooring material. When installed, base portion S will be substantially parallel with the floor surface, while central portion 122 will be transverse to the floor surface, thus providing a gradual, sloping surface between the two flooring materials of differing heights. Alternatively, flooring adapter device 110 can be secured to the floor surface before one or both of the flooring materials is arranged to provide a floor surface.
It will be appreciated that the preferred embodiment of flooring adapter device 110, as illustrated in FIGS. 3 and 4, is most suitable for use with concrete and 1/4-inch carpet. However, it is contemplated that flooring adapter device may be modified to accommodate flooring materials having varying dimensions.
In this respect, the dimensions of cavity 166, the width of base portion 132 and upper surface 120, and the slope of central portion 122 (i.e., angle Z), may vary to accommodate flooring materials of varying types and sizes.
