TECHNICAL FIELD
The disclosure herein relates to an architectural mesh panel, and more particularly, to an architectural mesh panel which simulates the look of a moiré pattern.
BACKGROUND
A moiré pattern is a secondary pattern created when two primary patterns (sometimes identical) are overlaid on a flat or curved surface while displacing them either linearly or rotationally one from another. That is, an independent pattern seen by an observer when two geometrically regular patterns (as two sets of parallel lines or two halftone screens) are superimposed. This pattern 10, 20 can be naturally evident or can be considered a form of an optical illusion, as shown in FIGS. 1A and 1B.
Moiré patterns can also be three dimensional if there is a depth displacement between the two primary patterns. This not only results in the creation of a new secondary optical pattern (or illusion), but it can also make the pattern change - appear as if it is moving, if the viewpoint of the observer is moving in relation to the fixed locations of the primary patterns.
Flexible metal mesh is widely used in cladding systems for buildings because it is aesthetically pleasing, provides security/safety, is easier to install than fixed panels and it can adapt simply to curved or angled building surfaces.
There are existing moiré building schemes that typically include an overlaid pattern system or a twisted element system. The overlaid pattern system uses two primary patterns, usually two or more cable groups or fixed panels that are displaced linearly or rotationally. Further, the cable groups can also be varied in depth from one another to further increase the effect. As shown in FIG. 2, the overlaid pattern 30 includes vertical and linear displaced cable groups having a varying depth to provide an aesthetical design in the building cladding system.
The twisted element system does not provide as strong of a secondary pattern as the overlaid pattern system, but is able to achieve a similar effect with one primary pattern and a contrasting background due to the depth created via the twisted elements. The more depth the elements have the stronger the moiré effect. However, the higher depth creates more wind load on the building and it requires more structural members/anchor points to absorb these forces.
While these systems are both successful at creating the desired effects for the building cladding they are difficult to install, expensive and are not easily adaptable to irregular building surfaces. The expense is partly due to the installation costs associated with the systems but also because of the need for either two primary patterns or heavy anchor systems to create the effect. The moiré effect is of interest in building cladding systems because it can give the appearance that the surface of the building is moving when a viewer is walking or driving by the location during the day or night, if properly lit.
Accordingly, it would be desirable to provide an easy to install inexpensive moiré-like architectural mesh system that can create variable patterns for building exteriors and interiors as well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A portion of an architectural mesh panel in accordance with an exemplary embodiment of the disclosure is shown generally in FIG. 3 by reference numeral 100. Architectural mesh 100 preferably comprises a flat wire mesh including a plurality of spaced rods 120 disposed in succession, each rod 120 having two ends 122 and 124. Mesh 100 includes a plurality of rows of pickets 130 shown as being vertically disposed in FIG. 3 and interconnecting the succession of rods. Each row of pickets 130 is comprised of a plurality of links 140, each link 140 connecting a rod 120 with a following rod in succession.
In accordance with a first exemplary embodiment of the disclosure, pickets 130 comprise a plurality of substantially identical links 140; however, as described further below, not all the links 140 within a single picket are identical and not all the horizontally or vertically installed rows of pickets are identical.
More particularly, FIG. 3 illustrates a vertical installation of mesh 100 that is configured to present a curved surface. A contrasting background 110, such as the blue background illustrated, gives the appearance of moving stripes to an observer whose viewpoint is continuously changing from one side of the mesh towards the other.
However, since a curved installation of mesh 100 is not easily achieved or cost effective, the disclosure herein further uses the flexibility of an architectural mesh with a repeating pattern of opening sizes to achieve a moiré-like effect (simulated moiré) with only a single layer of mesh, i.e., one primary pattern, as shown by mesh panel 200, 300, 400, 500 in FIGS. 4-7. The architectural mesh panel 200, 300, 400, 500 naturally includes some depth, generally approximately 0.5″, which combined with a repeating pattern of opening sizes allows the panel to achieve the moiré effect. The mesh panel 200, 300, 400, 500 can be installed on flat, angled or curved surfaces in vertical, horizontal or angular installations. It does not require heavy anchor points, is easy to install, and costs considerably less than prior systems. Mesh panel 200, 300, 400, 500 can be front and/or back lit to provide a contrasting background and thus it can also function at night. The mesh patterns, as explained in greater detail below, can be varied to provide the “appearance” of stripes, rings or circles moving across the surface of a building or an interior wall based on the observers' movement and changing viewpoint, thus creating the optical illusion of movement on the surface of the building, but with no moving components.
Referring to FIG. 4, mesh panel 200 discloses a horizontal installation of pickets 230 and rods 220 in a flat surface configuration. Each of the pickets 230 includes a plurality of links 240 having a varying horizontal spacing as shown for example by links 240a through 240i. That is, as the spacing decreases from link 240a to link 240b the closer links create the appearance of a vertical stripe 250a. The spacing then increases from link 240c to 240d, and is followed by several smaller links 240e and 240f which create the appearance of a further vertical stripe 250b. Links 240g, 240h and 240i gradually increase in width before the width of the links deceases again to create the appearance of another vertical stripe 250c, followed by increasing width links and then decreasing width links which create the appearance of vertical stripe 250d. The pattern of increasing and decreasing width links creates a repeating pattern of the vertical stripes 250a-250d. The stripes 250a-250d, also referred to as “crests”, have different appearances due to the differing spacing of the links. Hence, because the spacing between the vertical stripes is not identical and the stripes are not identical, mesh 200 gives the appearance of irregular moving stripes of irregular width, i.e., crest cycloidal, to an observer whose viewpoint is continuously changing from one side of mesh 200 towards the other, as when a driver in a vehicle drives past a building onto which mesh 200 has been installed.
FIG. 5 illustrates a mesh panel 300 in a horizontal installation of pickets 330 and rods 320 in a flat surface configuration. Each of the pickets 330 includes a plurality of links 340 having a varying horizontal spacing as shown for example by links 340a through 340o. That is, as the spacing decreases from link 340a to link 340d the closely spaced links create the appearance of a vertical stripe 350a. The spacing then increases from link 340e to 340g, and is followed by decreasing width links 340h to 340k which create the appearance of a further vertical stripe 350b. Links 340l, 340m, 340n and 340o gradually increase in width before the width of the links deceases again to repeat the pattern beginning again with a link 340a and subsequent decreasing and increasing links to create the appearance of another vertical stripe 350a, followed by increasing width links and then decreasing width links which crease the appearance of another vertical stripe 350b. The pattern of increasing and decreasing width links creates a repeating pattern of the vertical stripes 350a and 350b. The stripes 350a, 350b have a similar or identical appearance due to the spacing of links 340b-340e defining stripe 350a being substantially identical to links 340i-3401 defining stripe 350b. Hence, because the spacing between the vertical stripes is not identical but the stripes are substantially identical, and the opening size of the links evenly increases and decreases across the width of the mesh panel, mesh 300 gives the appearance of regular moving stripes, i.e., cycloidal, to an observer whose viewpoint is continuously changing from one side of mesh 300 towards the other, as when a driver in a vehicle drives past a building onto which mesh 300 has been installed. That is, the cycle from the smallest link to the largest link, and back again, will be evenly spaced so the widest link opening is in the middle of the cycling pattern.
Referring to FIG. 6, mesh panel 400 discloses a horizontal installation of pickets 430 and rods 420 in a flat surface configuration. Each of the pickets 430 includes a plurality of links 440 having a varying horizontal spacing as shown for example by links 440a through 440q. That is, as the spacing decreases from link 440a to link 440b, the closer links 440b-440d create the appearance of a vertical stripe 450a. The spacing then increases from link 440e to 440g, and is followed by a smaller link 440h, and then smaller, closer links 440i-440k which create the appearance of a further vertical stripe 450b. Links 440l to 440p gradually increase in width before the width of the links decease again at link 440q, and repeat a pattern beginning with link 440a to create the appearance of repeating vertical stripes 450a and 450b. The stripes 450a and 450b have substantially similar appearances due to the substantially similar spacing of the links. However, because the vertical stripes and the spacing between the vertical stripes are not identical and the opening size of the links does not uniformly increase to the widest link of the mesh panel or uniformly decrease as cycling back to the narrowest link, mesh 400 gives the appearance of irregular moving stripes, i.e., offset cycloidal, to an observer whose viewpoint is continuously changing from one side of mesh 400 towards the other, as when a driver in a vehicle drives past a building onto which mesh 400 has been installed. That is, the cycle from the narrowest link to the widest link, and back again, is offset so the widest link opening is offset from the middle of the cycling pattern.
FIG. 7A illustrates a mesh panel 500 in a horizontal installation of pickets 530 and rods 520 in a flat surface configuration. Each of the pickets 530 includes a plurality of links 540 having a varying horizontal spacing, such as links 540a-540i shown on the leading edge of mesh 500. However, unlike the previous discussed embodiments, each of the pickets is not identical to an adjacent picket disposed in the transverse direction. Hence, the width opening of corresponding vertically aligned links in a first picket 531 may be different from the width opening of links in a second picket 532, which is different still from the width opening of links in a third picket 533, and so on in a repeating pattern to achieve the desired appearance in mesh 500. More particularly, as the spacing decreases from link 540b to link 540d and then increases from link 540e to link 540g, in the leading row, the closely spaced link area creates the appearance of a generally vertically disposed stripe 550b. However, since all the pickets 530 are not substantially identical, the stripe 550b is not symmetrical from the trailing edge (bottom) to the leading edge (top). As shown best by way of example in FIG. 7B, in picket 531 the width opening (spacing) of links 541b-541d is fairly close, whereas in picket 532 the width opening of link 542c is greater than the corresponding width opening of link 541c in picket 531. Still further, in picket 533 the width opening of link 543c is greater than that of the corresponding link in picket 532. The spacing then decreases in picket 534 for link 544c and decreases further in picket 535 for link 545c. As a result, an ellipsoidal shape is formed in mesh 500 which may be repeated along the vertical stripe 550b as well as in stripe 550a. Although only one link opening is identified, one skilled in the art will appreciate that varying the width vertically as well as horizontally can allow a variety of patterns to be formed. Hence, because the spacing between the vertical stripes 550a, 550b is not identical but the stripes are substantially identical, mesh 500 gives the appearance of irregular moving stripes including rings or circles or other ellipsoidal shapes, i.e., double cycloidal, to an observer whose viewpoint is continuously changing from one side of mesh 500 towards the other, as when a driver in a vehicle drives past a building onto which mesh 500 has been installed.
FIGS. 8A and 8B illustrate a mesh panel 600 in a horizontal installation of pickets 630 and rods 620 in a curved surface configuration. By varying a curved surface to be in phase or out of phase with the mesh spacing variations in the links, the effects can be more pronounced. Thus, while mesh 600 is substantially identical in structure to mesh 500 the use thereof in a curved installation further emphasizes the movement of the stripes 650a, 650b including rings or circles or other ellipsoidal shapes, i.e., double cycloidal, to an observer whose viewpoint is continuously changing from one side of mesh 600 towards the other, as when a driver in a vehicle drives past a building onto which mesh 600 has been installed.
FIGS. 9A-9F illustrate a moiré architectural mesh panel in accordance with the disclosure, such as double cycloidal mesh panel 500, as viewed by an observer as they pass in front of the mesh at various angles. More specifically, the viewing angle varies in FIGS. 9A to 9F from 0, 15, 30, 45, 60 and 75 degrees, respectively, and one can appreciate the variance in shape of the vertical stripes and the geometrical patterns within the stripes as the viewing angle changes.
The exemplary embodiments described above disclose symmetrical rows of vertically aligned cubist links defining vertical stripes, as well as stripes including ellipsoidal shapes and the like. One skilled in the art will recognized that the spacing between the links can be adjusted to achieve any geometrical shape desired, including but not limited circles, rings, wedges, rectangles, and the like.
In addition, the exemplary embodiments described herein disclose horizontal installations intended for wall surfaces. However, one skilled in the art will recognize the vertical installations of any described mesh is also possible, and that the mesh may also be used on ceiling surfaces.
While the disclosure herein has been described with respect to particular exemplary embodiments of the invention, this is by way of illustration for purposes of disclosure rather than to confine the invention to any specific arrangement as there are various alterations, changes, deviations, eliminations, substitutions, omissions and departures which may be made in the particular embodiment shown and described without departing from the scope of the present invention as defined only by a proper interpretation of the appended claims.
