20080014398
The present invention relates generally to a wire mesh panel and, in one possible embodiment, to a wire mesh panel comprised of generally planar wires which may also comprise flat wires with twists therein.
Safety glass, also known as wired glass, is well known in the prior art. Safety glass may utilize a wire mesh support as discussed in more detail in the cited patents listed hereinafter. Safety glass is utilized to provide protective windows that permit visual perception therethrough. Accordingly, the wire mesh utilized in prior art safety glass is typically of very small diameter wire with wide openings in the mesh so as to avoid obstructing vision through the glass. Due to the small diameter wire mesh with large openings therein that permit maximum vision therethrough, there is effectively very little inherent strength in this wire mesh. To increase the strength of the wire mesh utilized in safety glass, the wire mesh is formed by twisting the wires together at each connection and/or welding the mesh.
The prior art safety glass focuses on minimizing the appearance of the wire inside the glass. The result of using relatively few strands of minimized diameter wire in the support mesh significantly improves the ability to look through the glass by blocking only a very small percent or a fraction of a percent of the light through the safety glass, but also provides a relatively low strength glass support structure as compared to many other reinforcing materials.
The following patents show prior art related to the above:

This summary is not intended to be a limitation with respect to the features of the invention as claimed, and this and other objects can be more readily observed and understood in the detailed description of the preferred embodiment and in the claims.
For a further understanding of the nature and objects of the present invention, reference should be had to the following detailed description, taken in conjunction with the accompanying drawings, in which like elements are given the same or analogous reference numbers and wherein:
While the present invention will be described in connection with presently preferred embodiments, it will be understood that it is not intended to limit the invention to those embodiments. On the contrary, it is intended to cover all alternatives, modifications, and equivalents included within the spirit of the invention.
Referring now to the drawings and, more particularly to
Typically, the open area will be less than about fifty percent of the total area of the wire mesh but could be a smaller or larger percentage. The reflectance of the wire mesh is also controlled. Different sides of the wire mesh panel may have different amounts of reflectivity. A preferred range of reflectance ranges from total reflectance of the light, up to one hundred percent to a smaller amount of reflectance such as about fifteen percent.
The wire mesh is preferably selected not only for strength but also for aesthetic purposes. Accordingly, one possible object of the invention is not necessarily to enhance vision through wire mesh panel 10 but instead to provide a generally very strong and aesthetically pleasing construction panel that may be utilized for a wide variety of construction purposes such as in furniture, building walls, and the like. The wire diameters may have a fairly wide range of diameters such as between 0.02 mm to 2 mm or larger. As the diameter decreases, additional wire strands are utilized to keep the open areas smaller. The wires may be of any type such as copper or stainless alloys or any suitable wire with any type of finish. In one embodiment, due to the limited open areas, most of the light striking panel, will be reflected and/or absorbed.
In another embodiment, the wire mesh panel is suitable for use in hygienic environments. For instance, screens may presently be provided in hygienic environments such as restaurants, hospitals, and the like which are difficult to clean. The present invention provides an easily cleanable panel with the aesthetic appeal providing by a screen.
In
Preferably transparent or translucent panels 14 and 16 are made of any suitable material such as glass, plastic, lexan, polycarbonates, acrylics, any suitable materials discussed hereinbefore, or any other suitable relatively clear or translucent material such that the wire mesh is visible through the panels. Translucent panels 14 and 16 may be rigid but could also be flexible to a certain extent so that panel 10 may be bendable by a certain amount. For a rigid construction either the translucent panels or the mesh may be rigidly formed. Considerations for panels 14 and 16 may also include insulation properties, clarity, any tinting, tensile strength, and so forth. A single translucent panel may also be utilized wherein the mesh is encapsulated such as by melting into the glass whereby the result is a wall like structure with a relatively large surface area with length and height much larger than the thickness of the panel.
The panels may be designed to provide a selected amount of light to be passed through or reflected such that an architect can make a panel selection based on such considerations. Thus, an architect will be able to design the amount of light coming through the screen such as through skylights, window panels, or the like. Various factors can be controlled in the construction of wire screen to control reflectance, light scattering, and translucence or the amount of light passing through the screen. Such control techniques may comprise selecting one or more of factors such as the wire mesh weave, selecting twists in wires to control reflectance, selecting a percentage of open regions of the wire mesh to affect both reflectance and translucence, selecting one or more cross-sectional shapes for a first plurality of wires and a second plurality of wires which may be woven together, selecting a diameter of the first plurality of wires and the second plurality of wires, selecting a texture of the first plurality of wires and the second plurality of wires and/or selecting a reflectance, gloss, polish, or the like, of the first plurality of wires and the second plurality of wires
In one preferred embodiment, the wire mesh is bonded, epoxied, glued, or the like between panels 14 and 16 and/or other panels as indicated in
Wire meshes 12A and 12B in
The warp wires and the shute wires may or may not be identical and may have different types of cross-sections as shown in
Note that the wires may have much smaller diameters. For instance each warp member 36D, 38D and shute member 40D, 42D might comprise many separate smaller diameter wires. Thus, for instance, 36D may comprise many individual smaller wires which may be unwoven and aligned parallel to each other or which may be woven together to form 36D. Any cross-sectional type of wire maybe utilized herein, as indicated in
Thus, wire mesh panel 10 could be woven with a combination planar and non-planar cross-sectional type members or filaments and with a wide range of different diameter wires. For instance, planar wires, or wires laid together or woven together to form planar members, may be woven with round cross-sectioned wires or wires laid together or woven together to form round members. Planar wires or wires laid to form planar patterns or members may also be woven with different cross-sectioned planar wires or wires laid in planar fashion to form other members, e.g., rectangular cross-sectioned planar wires or members with triangular cross-section planar wires or members.
Referring to intersections 54D, 56D, and 58D in
In another embodiment of the invention, planar surface wires such as planar surface wires 36D, 38D, 40D, and 42D in
In yet another embodiment, the wire mesh may utilize wires that are welded at each intersection to provide additional strength, such as shown in the cross-sectional view of
Panel 10 effectively forms construction material that can be utilized in a wide variety of ways. For instance in
One possible preferred embodiment panel 100 is shown in exploded form in
Layers 102 and 104 may comprise different materials. For instance, layer 102 may comprise glass and layer 104 may comprise polycarbonate. Moreover, additional layers such as glass layers, plastic layers, and polycarbonate layers, with additional inner layers therebetween may be utilized, e.g. glass, polyvinyl butyral, glass, polyvinyl butyral, glass, urethane, polycarbonate. Accordingly, the example of
The use of wire mesh 110 therewith opens the possibility for greatly increasing the strength of panel 110 to provide blast resistant, hurricane impact resistant, bullet resistant, forced-entry resistant, or simply decorative panels that are aesthetic and attractive. In one preferred embodiment, panels such as panel 110 may be easily mounted in a similar manner as one might mount panes of glass into a window frame.
Plastic, films, resins, vinyls, urethanes, polyvinyl butyral, PVB, EVA, and/or other suitable materials some of which have been listed hereinbefore, may be utilized inside of outer panel layers 102 and 104 to form one or more inner layers of materials which bind outer layers 102 and 104 together with mesh 110. In the embodiment shown in
One embodiment of a method for making a panel in accord with the invention comprises steps such as compressing and heating layers 106 and 108 whereby the openings in mesh 110 are filled and the outer layers 102 and 104 are secured together. In this way, panel 100 becomes a solid, high-strength construction as shown in cross-section in
As another possible example, PVB foils may be utilized for layers 106 and 108. PVB foils, in one embodiment, may be best utilized during manufacturing in a climate regulated atmosphere. One possible type of suitable PVB foil is sold under the name Trosifol. Trosifol foil can be used for manufacturing panel 100 simply with a vacuum bag and without the need for heat from using, for instance, an autoclave. However, with normal PVB foils, panel 100 may be formed by being put into an oven or autoclave and heated ninety to one hundred forty degrees Centigrade wherein pressure and heat are applied. PVB laminated glasses have good sound deadening and are generally considered to be rated as safety glass as may be especially desirable for use in stairways and/or other constructive glass applications.
As another possible example, EVA foil may be utilized which may be utilized for manufacture of panels 100 without the need for larger equipment. Generally, foils such as PVB or EVA, may be utilized as layers 106 and 108 which surround mesh 110, and which are utilized between glass layers 102 and 104. In order to pull out the air between the foils and the mesh, the whole construction 100 may be placed into a vacuum bag. The vacuum bag under constant vacuum is placed into an oven and heated at the desired temperature. Utilizing normal PVB, an autoclave is utilized to produce heat and pressure as necessary.
For visual effects where twisting of wires may be used in accord with one embodiment of the invention, the twist is more visible if the wires utilized comprise a cross-section such that twisting produces a visually perceptible change, e.g., a twist in a wire with a rectangular cross-section as compared to a twist in a perfectly round cross-section which may not be readily discernible.
Variations of the flat wires in mesh 10 can be readily selected to produce desired architectural effects. Such variations of the flat wires to produce desired architectural effects include but are not limited to variations in width, opening spaces, reflectance, type of metal or alloy, finish of the metal, type of weave, and/or other variations disclosed hereinbefore, and/or the number and spacing of twists as discussed hereinafter. ” Wire Mesh Panel and Method” Inventors: Ruediger Tueshaus and Patrick McGrenera Twists in warp and shute wires 112 and 114, such as twists 116 and 118, and the like, may be inserted at random positions, at irregular positions, and/or in a pre-determined pattern, as discussed hereinbefore. In one possible preferred embodiment, the twists are produced within particular portions of the wire rather than spread along the length of the wire. Each twist may involve at least one-half turn of the wire but could utilize one or more complete turns and each twist may have a preset, random, or irregular numbers of turns. The twists may be positioned anywhere in the weave including at the intersections, between the intersections, at either side of the mesh, at any specified or regular positions, at irregular, random, and/or regular spacings between twists and/or intersections and/or positions within the mesh, and/or at some combination of the above factors or other desired factors. As a general rule, while the shute or warp wire may be twisting, the shute and warp wires are not twisted together to form an intersection, although if desired they could be.
The spacing, number, location, and other various features of the twists may be selected based on the type and/or amount of lighting, reflection, or other visual effects which may be desired. The visual effects of wire mesh panels in accord with the present invention are discussed hereinbefore.
The weave may be a particular pattern, an irregular pattern, and/or a random pattern, as desired. If twists are desired, the twists may be positioned only in shute wires or only in warp wires or both.
It will be understood that terms such as wire mesh, woven or knitted mesh, and the like are often used interchangeably herein. By planar members it is meant herein that at least one surface of the wire, member, or filament substantially comprises a plane, has a cross-section which appears to provide a relatively flat continuous, smooth surface, or at least has a variable shape so that one portion of the cross-section is readily visually distinguishable from another portion. The cross-sectional shape may be substantially constant even if the wire itself is not exactly horizontal or straight but instead follows the weave of the mesh and if the wire includes turns or twists. In one preferred embodiment, the shape of the cross-section will preferably be continuous along the length of the member, filament, or wire. Thus, calendaring an already woven screen will not produce planar members with continuous, regular surfaces as discussed herein, because calendared filaments or wires do not have substantially the same cross-section along their length. Instead, calendaring will produce variations in the cross-sections of the wires or filaments at the knuckles. However, calendared screens may also be utilized in accord with the present invention.
Moreover, the woven planar filament meshes of the present invention may be molded into other shapes, which may not be relatively or perfectly flat, or which may be pleated or rounded, and/or may be utilized in any desirable shape within any type of filtration equipment which may not utilize vibration but may also utilize pressure or other means of filtration. It will be understood from review of the disclosure of the present invention that many different types of weaves and combinations utilizing woven planar members in accord with the present invention may be utilized.
The woven planar wires may comprise fibers of various types, stainless steel, carbon steel, other visually pleasing metallic materials, combinations thereof, colered plastic, or any other suitable material. A screen in accord with one possible embodiment of the present invention is preferably woven. One additional advantage of woven screens is a built-in resistance against vibration and the strength thereof as may be desirable for certain construction projects.
In one possible embodiment, woven wires such as wires 112 and 114 may comprise diameters of 0.5 millimeters or less, if desired, and may be woven in rolls with decorative aspects such as comprising various metals with various colors. As noted above, in one preferred embodiment, the wires are flat to thereby provide reflection visual effects. As already noted above, other visually effective meshes may include herring bone meshes and the like. In another embodiment, smaller wires in the range of 0.025 mm or so in 100 mesh mesh may be utilized to produce visually pleasing and/or practical screens, e.g., radar antennas.
Thus, the foregoing disclosure and description of the invention is therefore illustrative and explanatory of one or more presently preferred embodiments of the invention and variations thereof, and it will be appreciated by those skilled in the art that various changes in the design, organization, order of operation, means of operation, equipment structures and location, methodology, and use of mechanical equivalents, as well as in the details of the illustrated construction or combinations of features of the various elements, may be made without departing from the spirit of the invention. As well, the drawings are intended to describe the concepts of the invention so that the presently preferred embodiments of the invention will be plainly disclosed to one of skill in the art but are not intended to be manufacturing-level drawings or renditions of final products and may include simplified conceptual views as desired for easier and quicker understanding or explanation of the invention. It will be seen that various changes and alternatives may be used that are contained within the spirit of the invention. Moreover, it will be understood that various directions such as “upper,” “lower,” “bottom,” “top,” “left,” “right,” “inwardly,” “outwardly,” and so forth are made only with respect to easier explanation in conjunction with the drawings and that the components may be oriented differently, for instance, during transportation and manufacturing as well as operation. Because many varying and different embodiments may be made within the scope of the inventive concept(s) herein taught, and because many modifications may be made in the embodiment herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
This application is a continuation-in-part of U.S. patent application Ser. No. 10/620,544 filed Jul. 16, 2003.
