Abstract

Carpet tiles that can be positioned adjacent each other on a flooring surface to create the appearance of light emanating from the floor or the illusion of depth. The flooring having the properties of this invention is achieved by producing rectilinear flooring modules that have color distributed on the module from very dark to very light across the tile from one edge to the opposite edge. Tufts of yarns provide a "background" of constant color and intensity along the longer dimension of the tile that progresses across the tile from very dark along one side to very light along the other side. Between the dark and light tiles edges is an intermediate region of progression of colors that begin dark and become light. The intensities of the colors in the intermediate region preferably progress from bright to relatively muted between the dark and the light tile edges so that the intensity of the light color tile edge is greater, and thus the light color is more prominent on the carpet tile, than the color adjacent it on a carpet tile. This results in the light color edges "standing out" on the carpet tiles, which contributes to the illusions created by this invention, especially when the light color edges are positioned adjacent dark color edges.

Description

MODULES OF TAPETES ASYMMETRALLY SHADED E INSTALLATIONS OF TAPETTE MODULES THAT CREATE ILLUSIONS OF LIGHT AND DEPTH Field of the invention This invention relates, generally, to mats modules, which may be placed adjacent to each other, on a floor surface, to create the appearance of a light which emanates from the floor or provides the illusion of depth.

BACKGROUND OF THE INVENTION Innumerable different variables, such as, for example, the color, model and material, can be altered for the impact and extensive variation of the appearance of the covers of a carpet floor, even the resulting floor, if it is In the form of wide loom weaving or carpet modules, they have traditionally appeared as two-dimensional on the floor surface. While most rugs invariably contain different fur heights, such relatively minor variations in fur height fail to impart a significant, real or apparent depth to the floor surface. Commercial carpet modules have been used more widely in situations where large designs and pronounced designs are not appropriate. For example, while such modules have been widely used in large open-plan office facilities spaces, those spaces are typically occupied by office furniture and partitions that make it impossible to see any large floor area. Appropriate designs for such spaces are small scale, which are reinforced by the design constraints associated with the modular form of the carpet module. The contexts in which the carpet modules have traditionally been used and the aforementioned design considerations and other considerations have resulted in strong tendencies to design carpet modules with a relatively uniform appearance, so an assembly of the carpet modules on a floor will have a similar, relatively uniform appearance. In larger spaces, such as in airport contests, considerations of such uniformity of appearance, as well as in relation to dyeing and replacing damaged or stained modules, have often been of paramount interest. As a result, the conventional design of carpet modules has not been provided with such large, prominent designs, often desired for large spaces, particularly "public" spaces, such as lobbies and dance halls. The carpet modules enable the alteration of the appearance of a floor covering, simply by the rearrangement of all or some of the individual carpet modules on the floor.

Compendium of the Invention Light is a central, recurrent metaphor for humanity, used throughout the ages, to signify divine wisdom. Drawing on this rich metaphoric heritage is as old as humanity, and as universal as music, this invention provides modular floor designs, which include particularly certain designs of carpet modules, suitable for large spaces, as well as areas of minor scale. In the designs of carpet modules and the configurations of this invention, the particular progressions and placements of color, intensity and shading, and the particular placement of the modules in mutual relation in a floor installation, results in the parquet of designs to Large scale, highlights, which include regions of the floor that appear or have a spatial depth or that emanate light from the floor. The floor, which has the properties of this invention, was achieved by producing rectilinear floor modules, typically rectangular (preferably with a length double the width) having the color, distributed over the module, from very dark to very clear, through the module, from one edge (preferably the longest) to the opposite edge. In one embodiment of this invention, the tassels of high yarns provide a "background" of constant color and intensity, along the greater dimension of the module, which progresses through the module, from very dark, along one side, to very clear, along the other side. Between the dark and light regions, there is an intermediate region of color progression that starts dark and becomes clear. In this mode, the heights of the wire tassels are controlled which form a pattern of a simple appearance compatible with all the other threads, which are present on the module, in order to impart a pattern of certain configurations on the module.

It is preferable that the color, in the intermediate region, progress from dark to light between the dark bands and the light bands. This facilitates the uniform transition of color, between the dark color and the light color through the intermediate region. While any number of colors can be used in the intermediate region, it is preferable that sufficient colors be used to ensure this uniform transition. Also, the intensities of the colors in the intermediate region progress preferably from bright to relatively matte, between the dark bands and the light bands, so the intensity of the light color is greater and so the light color is more prominent in the carpet module , that the adjacent color on a carpet module. This results in the light-colored edges "protruding" over the carpet modules, which contributes to the illusions created by this invention, especially when the light-colored edges are placed adjacent to the dark-colored edges. In two-module installations of this invention, with adjacent clear regions, the presence of the module areas shaded gradually in the lighter region will provide an illusion of depth of light emanating from the "soft" edge regions of the floor. In installations of such modules with a clear region abutting a dark one, a similar illusion of depth or light is produced, but with an indistinct margin that opposes the sharper defined edge, as can be produced by the light coming from behind of a solid object, like an object on the floor. The rectangular modules in pairs of this invention can provide large square modules with central, highlighted regions, and a wide variety of other designs can be produced, varying the arrangement of the modules on a floor.

Detailed Description of the Drawings This invention relates to carpet modules, having bands of dark and light colors, placed on at least one pair of opposite edges of the modules. For the purposes of this patent, an "edge" refers to the regions on the face of a carpet module, close to the actual side edge of the module. The number of possible patterns that may appear on the modules of this invention is virtually unlimited, as long as this color scheme (ie, having light and dark bands, according to this invention) is present on the modules. Alternatively, the modules of this invention can be provided without any tassel or other pattern from the progression from light to dark through the module.

Figures 1 to 2 illustrate, respectively, alternative embodiments of the carpet strip patterns 10, 20 and 30, all consistent with this invention. The carpet modules, which use the strip patterns, shown in Figures 1-3, can be seen in Figures 5-8, with reference to which the understanding of the following will be facilitated. Figures 1-3 each show a complete "repeat" of the respective patterns 10, 20 and 30. A complete "repeat" is a complete segment of the pattern. Generally, a strip of mat will be formed with a pattern that is repeated across the width of the strip, ie with multiple repeats of pattern across the strip, as well as the length of the strip. A strip, which has any number of complete or partial repeats of a pattern, can be produced depending, in part, on the manufacturing capabilities, which include the equipment used to produce the strip. This strip can then be placed in the carpet modules of each configuration or also with the condition that the resulting modules display the color scheme, as indicated below. Also, the modules of this invention do not need to be cut from a strip, but rather the colors and the pattern (if any) can be printed on the face of the previously formed carpet modules. As discussed above, the carpet modules of this invention can be manufactured in other ways, by making a floor covering strip and then cutting the strip into carpet modules. For example, a strip may be, but does not have to be, made using a conventional machine that forms tassels on the mat, to form the textile face covering the floor and attach that face to an appropriate backing structure. Among other alternatives, the face of the strip can be produced by the tasseling machine on the mat, which has 1/4 (6.35 mm) and 1/8 (3,175 ram) gauge needle bars. Controlling the "threading" (that is, the arrangement of the colors of threads dedicated to the needles of the machine) and the height of the tassels of the thread (that is, the further away the part of the thread is pushed through the backrest) primary, the greater the height in the finished mat module and the more predominant the color of the yarn will be to an ordinary observer), a desired pattern (and its full and partial repeats, if desired) can be formed into a strip.

Each module is threaded with a dedicated thread type (for example, simple color, space dye, barber pole type, etc.) and color (for the purposes of this patent, "color" includes variations in shades of a only color). The pattern is formed on the strip by color contrast between adjacent yarn colors in a single needle row, by the color content between the yarn colors in the first row of needles and the second row of needles, and by the prominence of particular threads on the strip face, as a result of the height of the tassels. Thus, the types and colors of yarns used must be selected to achieve the desired contrast. At least two colors are generally necessary to achieve the color contrast. However, it is preferable to use a wide variety of colors in the modules of this invention. The threading must include threads of at least one dark color and at least one light color. These threads should form tassels, so bands, relatively broad, of dark color and relatively broad bands of light color, appear alternately across the band. Additional colors that are between the dark and light colors (ie, lighter than the dark color and darker than the light color) create an intermediate region that contains bands of color between these light and dark bands. It is preferable that colors in this intermediate region progress from dark to light between dark bands and light bands. This facilitates the uniform transition the color between dark color and light color, through the intermediate region. While any number of colors can be used in the intermediate region, it is preferable that sufficient colors be used to ensure this uniform transition. It is possible, for the purposes of this invention, to use a single color that progresses from the dark shadow to the clear shadow through the module. However, this invention is preferably practiced using a series of different colors (not just shades of a color) that progress from dark to light through the module. Also, the intensities of the colors in the intermediate region progresses preferably from bright to relatively matte, between the dark bands and the light bands, so that the intensity of the light colored module edge is greater, and so the light color is more prominent in the carpet module, than the adjacent color in a carpet module. This results in the light-colored edges "standing out" on the carpet modules, which contribute to create illusions by the invention, especially when the light-colored edges are placed adjacent to the dark-colored edges. The strip of mat with this color scheme can then be divided into individual carpet modules. The longitudinal cuts should be placed on the strip so that they are inside, and preferably in the center of, each dark and clear alternative band on the strip. Thus, the light and dark bands must be made sufficiently wide in the strip, so that the modules on both sides of a longitudinal cut have a portion of the band (or light or dark) through which the longitudinal cut is made. In this way, a module cut from the strip will have a portion of the dark band at one edge and a portion of the clear band at the opposite edge, separated from the dark band by an intermediate region containing colored bands. When these bands of light and dark colors are placed on the strip, they will obviously depend on the size of the modules that are trying to be cut from the strip. Side cuts can be made anywhere along and below the strip, depending on the desired configuration (eg, square, rectangular, etc.) and the dimensions of the modules.

The following is an example of a threading that uses a variety of colors to create the strip face. This threading represents only half of the 1/8 gauge threading (3.175 mm) for a 1.83 m wide machine that forms tassels, and thus the threading will need to be repeated in the machine to produce a larger width face. While this specific threading example is provided, it should be understood that any threading of the machine may be created, in accordance with this invention, as long as the resulting strip, when properly cut, results in carpet modules having a color band. dark and a light colored band in at least one pair of opposite edges, in accordance with this invention.

Rows of Caliber Needles 1/8 (3.175 mm) Needle Position Thread 1-15 A 16-24 AB 26-35 B 36-45 BC 46-55 C 56-65 CD 66-75 D 76-85 FROM 86-95 E 96-105 EF 106-115 F 116 -125 FG 126-135 G 136-145 GH 146-175 H 176-185 GH 186-185 G 196-205 FG 205-215 F 216-225 EF 226-235 E 236-245 FROM 246-255 D 256-265 CD 266-275 C 276-285 BC 286-295 B 296-305 AB Rows of 1/4 gauge needles (6.35 mm) With this threading, the phono color scheme of the resulting band is symmetrical about the longitudinal, central axis of the strip. Such symmetry, however, is not required. The bottom of the strip forms tassels by needles of 1/8 gauge (3.175 mm). The tassels produced by 1/8 gauge needles (3.175 mm) will generally be of uniform height. While 1/8 gauge needles (3.175 mm) are threaded with solid colored threads, other types of threads (eg, "barber pole" type, stained in spaces, etc.) can be used. With this threading, the background changes colors frequently in a progression from dark to light to dark, etc. through the strip. The background includes eight different threads (A-H), each with a particular color. The threads A and H are of any color, dark or light. If thread A is the dark colored thread, thread H will be light in color, and vice versa. The B-G threads create the bands of colors in the middle region between the dark and light bands. In this example, the bottom yarn A is threaded on needles 1-15, the bottom yarns A and B are alternately threaded on needles 16 to 25, the bottom yarn B is threaded on needles 26-35, etc. . While the BG yarns of any color can be used (although, preferably, they are all lighter than the dark color, and darker than the light color), the BG yarns are preferably chosen so that the progression of colors from dark to light and the progression of color intensity from bright to relatively matte, is created in the middle region between the dark and light bands. The tassel pattern is produced on the strip by 1/4 gauge needles (6.35 mm). The height of the tassels formed by the gauge needles of 1/4 (6.35 mm) varies depending on the pattern. Thus, the patterns 10, 20 and 30 (or any other desired pattern) can be formed on a strip having the background described above, merely by adjusting the height of the tassels formed by the 1/4 gauge needles (6.35 mm. ). While 1/4 (6.35 mm) gauge needles can be threaded with any type of thread, the solid color threads have proven to be particularly well suited for this application. In this example, all 1/4 gauge needles (6.35 mm) are threaded with thread 1. While with this particular threading, only one type of thread color is used to form the pattern, this pattern can be formed by a variety of types and colors of yarn. The yarn 1 preferably, but not necessarily, has a relatively neutral color, which provides sufficient contrast to the background colors to graphically describe a pattern without departing overwhelmingly and significantly from the background colors. After the strip is formed, the modules can be cut from this strip. The modules, according to this invention, they can be cut into rectilinear configurations, which include the squares, but are preferably cut into rectangles. As explained above, the longitudinal cuts must be located so that they are located inside, and preferably in the center of, each dark and clear alternative band (formed in this case by A and H wires), on the strip. In this way, a module cut from the strip will have a portion of the dark strip (formed by the thread A or H) on one edge and a portion of the light strip (formed by the thread A or H) on the opposite edge , separated from the dark band by an intermediate region of colored bands (formed by the BG yarns). As an alternative, if an installation uses pairs of modules, with adjacent clear edges, as shown in Figures 6, 7 and 8, such "pairs" can be cut out of the strip as a single square module, which has a clear region in the middle of the square-grade module. A variety of practical considerations may be preferred for cutting the strip into rectangular modules, as described above, even if the modules are to be reassembled in pairs of modules, similar to their relative orientation on the strip. It should be understood that the modules, according to the invention, do not need to be produced from a strip of tassel mat. Rather, any method can be used to form modules having a color scheme, according to the invention. For example, the colors and patterns described here can be printed on modules of previously formed mats, with a pattern or only some pattern elements. The modules of the invention can be assembled on a floor surface, in numerous arrangements of similar and dissimilar modules, to create a number of different views, all of which give the impression of emanation of light from the floor. As noted earlier, the modules can be installed on the floor in the same relative positions they occupied on the strip. Alternatively, the modules can be placed in rows and columns in aligned form, but all or at least some of the edges of the dark modules are reoriented adjacent to the edges of the clear modules. This contrast between dark and light colors helps to create the illusion of light. However, in other situations, the modules of this invention can be installed as aligned columns that do not form rows of aligned modules. For example, the modules can be placed so that a column of modules appears up or down, to the columns of the adjacent module ("the installation method of sillar or square stone type"). This stages the horizontal seams at the edges of the module, formed by the adjacency of the "upper parts" and "the bottom parts" of the modules within the column. In still other installations, the installation method of "brick" type can be "desired, in the lime the" rows "are aligned, but the columns are staggered.Again, the placement of the dark edges, in relation to the edges clear, can be controlled by the installer, to vary the appearance of light on the floor.The square modules cut from the strip, or pairs of rectangular modules, which together form a square, can be installed in a pattern of "turn by a quarter turn ", which means that each module (or pair of rectangular modules) is placed in an orientation that has rotated by ninety degrees with reference to each adjacent module (or pair of rectangular modules.) These modules are typically produced with an arrow of address on the back so that the modules installed with the arrows all point to the same direction and will be in the same rotation orientation as they are inside the strip. A "quarter turn" type installation of half of modules for rectangular module pairs, they have their arrow pointing in one direction and the other half of the modules (or pairs of rectangular modules) have their arrow pointing in a direction displaced by ninety degrees from the direction of the dates of the first half. Modules of rectangular configuration, cut from the strip, can also be installed in a "fishbone" pattern, in which, similar to the installation method of a quarter turn, some modules are placed in an orientation rotated by ninety degrees with reference to the adjacent modules. More specifically, in a "fishbone" type installation, the pairs of L-shaped modules (which have a short side of an adjacent module with a long side of the other module) are nested (see Figure 4). Any mixture of these installation methods can be used. Alternatively, modules of different configurations can also be installed in the same installation. Although possible, it is not necessary for the modules of this invention to be installed on a floor surface only with other modules of this invention, which carry the same pattern. Rather, the modules of the invention that carry different or do not have patterns, can be mixed and installed in any way to vary the appearance of the floor. Also, a floor installation may include a mixture of modules of this invention and other modules, not in accordance with this invention, that carry different patterns and color schemes. The appearance of the light on the floor is particularly prominent in said installation when the modules, which are different from those of the invention, are relatively dark in comparison with the clear edges of the modules of this invention. The foregoing was provided for the purpose of illustrating, explaining and describing the embodiments of the present invention. Modifications and subsequent adaptations to these modalities will be apparent to those skilled in the art and can be made without departing from the spirit of the invention or the scope of the following claims. For example, different configurations and sizes of configurations of those illustrated, can be used. Similarly, a wide variety of color combinations are possible. Likewise, while the modalities, described above, have tassels, the face fabrics can also be woven in the Jacquard loom or in any other loom, and the face fabric can be fused or formed in other ways. Also, the patterns or portions of them can be printed on previously formed carpet modules. This invention can also be used to modulate floors or surface covering materials, in addition to carpet modules, such as a vinyl slab.

SUMMARY OF THE INVENTION Modules of mats that can be placed adjacent to each other on a floor surface are disclosed to create the appearance of light emanation from the floor or the illusion of depth. The parquet, which has the properties of this invention, is achieved by producing rectilinear floor modules that have the color distributed on said module from very dark to very clear, through the mat, from one edge to the opposite edge, Tassels of threads provide a "background" of constant color and intensity along the largest dimension of the mat, which progresses across the mat from very dark along one side a very clear along the other side. Between the edges of dark and light rugs is an intermediate region of color progression that begins with a dark tone and becomes clear. The intensities of the colors in the intermediate region progress preferably from bright to relatively matte, between the edges of the dark and light mat, so the intensity of the light colored modulus edge is greater, and thus that light color is more prominent on the carpet module than the adjacent color on that carpet module. This results in the light-colored edges "standing out" in the carpet modules, which contributes to the illusion created by this invention, especially when the light-colored edges are placed adjacent to the dark-colored edges.
