Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 62/111,512 filed Feb. 3, 2015 entitled “DEMOUNTABLE/MODULAR STRUCTURE SYSTEM.” Where in such provisional application is incorporated by reference. 
    
    
     FIELD OF INVENTION 
     The present invention relates to the field of temporary structures. More particularly, the present invention relates to a demountable panel system for constructing temporary structures. 
     BACKGROUND 
     Interior walls are used to divide buildings into segmented internal space, such as rooms. However, interior walls frequently require modification to the building structure in order to be secured in place. Moreover, soundproofing interior areas, especially, temporary spaces, frequently requires additional modification to the building structure, or the installation of semi-permanent fixtures. Furthermore, there is often a need for temporary outdoor shelters, such as at events and festivals. However, outdoor shelters capable of withstanding inclement weather often require extensive labor and structural anchoring. In addition, reconfiguration of the surface of walls, soundproofing, and shelters, such as with new paint, designs, sound dampening material, and the like, are labor-intensive and expensive. Thus there is a need for a demountable structure system that allows for the quick assembly and disassembly of temporary structures, temporary sound insulated structures, and temporary outdoor structures, and that allows for the quick reconfiguration of the surfaces of the structure. 
     SUMMARY OF THE INVENTION 
     In accordance with various aspects of the present invention, a demountable structure system is disclosed. The demountable structure system may have a roof system positioned atop one or more structural panel(s) and a floor system positioned beneath one or more structural panel(s). The structural panels may have different shapes, configurations, and features, and may support the roof system in order to form a demountable structure. Alternatively, the roof system is omitted and a wall or other structure can be formed from the structural panels. Each structural panel may have other features, such as finish panels, fabric panels, accessory mounts, recessed lighting, electrical outlets, etc. Finish panels allow for the quick reconfiguration of the surfaces of the structural panels, such as by allowing color or aesthetic design changes, sound proofing, and cosmetic reconfigurations. Some structural panels have sound dampening features, such as to form portable musician&#39;s sound booth. 
     The structural panel may have a panel shape and may comprise one or more joining member(s), joining edge(s), finish panel attachment point(s), and may have an internal structure. The structural panel may have a length, thickness, and height. The joining edge may comprise one or more face(s) of the structural panel oriented to abut a corresponding face of one or more additional structural panel(s), so that the structural panels may be connected together. The joining edge may comprise a boss edge, or a boss receiving edge. The joining member may comprise a member configured to interoperate with the joining member of another structural panel to selectably prevent the structural panels from being separated. The joining edge may comprise cam and/or a cam receiver. The internal structure may be an arrangement of panels, voids, and equipment inside the structural panel. Finish panel attachment points may comprise a bracket, clip, or other apparatus whereby a finish panel may be joined to the structural panel. 
     In accordance with various aspects of the present invention, the structural panels and/or roof system may be arranged to form a structure which is both readily disassembled, yet also sturdy.

     In accordance with various embodiments, and with reference to  FIG. 1 , a demountable structure system  2  may comprise a roof system  70  positioned atop one or more structural panel(s)  10 . The structural panels  10  provide support to a roof system  70 , and or a floor system  10 , forming an enclosed demountable structure. Alternatively, the roof system  70  may be omitted and floor system  10  may be omitted and a wall or other structure can be formed from the structural panels  10 . In accordance with further embodiments, and with reference to  FIGS. 1-10G , a demountable structure system  2  ( FIG. 1 ) may further comprise a combination of additional features such as finish panels  60 , fabric panels  80 , accessory mounts  90 , recessed lighting  97 , and electrical outlets  98 . Some structural panels  10  have sound dampening features, such as to form portable a musician&#39;s sound booth, or other structure. In various embodiments, one or more such element(s) may be omitted. In further embodiments, any number of one or more such element(s) may be included in a demountable structure system  2 . While certain example configurations are discussed herein, numerous features and embodiments of demountable structure system  2  may be achieved in accordance with various exemplary embodiments of the present invention. 
     In accordance with various embodiments, and with reference to  FIGS. 1, 2, 3A -B,  6 A-B, and  6 E, a demountable structure system  2  may comprise one or more structural panel(s)  10 . A demountable structure system  2  may further comprise structural panels  10  arranged to form an enclosure, such as a room, or a tent, or other structure. In various embodiments, a demountable structure system  2  comprises structural panels  10  joined together and arranged in various ways. For instance, a demountable structure system  2  may have structural panels  10  mountable between (but not permanently attached to) the floor and ceiling of a building. The demountable structure system  2  may comprise structural panels  10  arranged to form a free standing enclosure, or arranged to form a single free standing wall, or arranged to form a group of assembled walls with an attached assembled roof but no floor, or arranged to form a group of assembled walls with an attached assembled roof and with an attached floor, or any other desired arrangement. 
     With attention to  FIGS. 1, 6A, 6B, and 6D -F, a demountable structure system  2  may further comprise one or more finish panel(s)  60 . Finish panel  60  may be mounted to a face of the structural panel  10  to enhance the appearance, sound dampening, durability, or other characteristics of the demountable structure system  2 . In demountable structure systems  2  having structural panels  10  arranged to form an enclosure, finish panels  60  may be arranged on the interior side (e.g., facing inward toward the center of the enclosure) of the structural panels  10 . Finish panel  60  may be made of different materials. For instance, the finish panel  60  may be made from wood, metal, acrylic, artificial grass, drywall, fabric, sound dampening material and the like. In other embodiments, the finish panel  60  may be made of metal such as reflective metal, glass such as colored glass, wood such as wooden slats, or any other material creating a desired effect and aesthetic. In various examples, the structural panels  10  may have a two-millimeter and up to 6-millimeter thick sound absorbing rubber membrane loaded vinyl layer on the interior facing face. To improve the visual appeal of the demountable structure system  2 , one or more finish panel(s) made of a different material may be mounted on the interior side of the structural panels  10 , hiding the vinyl layer. 
     With particular reference to  FIGS. 1, 7A -E,  8 A-D, and  9 A-E, the demountable structure system  2  may further comprise a roof system  70 . A roof system  70  may be a panel style roof system (an exemplary roof system is shown in  FIG. 9E ), or may be a tent style roof system (an example of which is shown in  FIG. 7A ), or may be a rigid tent style roof system (an example of which is shown in  FIG. 7E ). A panel style roof system may comprise a roof made of structural panels  10 . A tent style roof system and a rigid tent style roof system may comprise a roof made of a canvas  61  stretched over various other features discussed further herein. Moreover, a roof system  70  may comprise any arrangement of features and elements covering the top of the demountable structure system  2 . 
     Turning now to  FIGS. 1 and 6C , the demountable event tent structure system  2  may also comprise one or more fabric panel(s)  80 . For instance, one or more structural panel(s)  10  may define an aperture  81  desired to be selectably covered. A tube slide fastener  82  may retain the fabric panel  80  over the aperture  81 , as desired. The fabric panel  80  may be cloth, or plastic, or natural or synthetic fibers, or any other similarly flexible material. 
     With reference to  FIGS. 1, 10C, and 10D  the demountable structure system  2  may comprise an accessory mount  90 . An accessory device  95  may be connected to the accessory mount  90 , and subsequently may be removed, or may be replaced with a different accessory device  95 . For instance, accessory devices  95  may be televisions, computer displays, signs, lighting, and the like. Fixtures, signage, electronic devices, and other apparatus may be supported by the demountable structure system  2 . The accessory mount  90  enables the ready connection and disconnection of other apparatus to and from the demountable structure system  2 . Thus, the demountable structure system  2  may be readily repurposed. 
     As illustrated in the exemplary embodiments shown in  FIGS. 1 and 10D , the demountable structure system  2  may also comprise recessed lighting  97 . For example, recessed lighting  97  may be disposed in the structural panel  10 , for example, a tent transverse header panel  19  ( FIG. 10D ), although recessed lighting  97  may be disposed in any structural panel  10 . 
     Similarly, the demountable structure system  2  may also comprise electrical outlets  98 . For example, electrical outlets  98  may be disposed in the structural panel  10 , for example, a corner pillar panel  18 , although electrical outlets  98  may be disposed in any structural panel  10 . 
     Electrical connectivity, such as for recessed lighting  97 , electrical outlets  98  and any other desired electrical connectivity (for example, as may be provided in association with an accessory mount  90 ) may be provided by connectors. For instance, with reference to  FIGS. 1 , and  10 A-G, in various embodiments, the electrical outlets  98 , and/or recessed lighting  97 , and/or other desired electrical connectivity receive electrical power from input connectors  99  and/or interpanel connector systems  94  associated with the structural panel  10 . In various embodiments, the input connector  99  is installed in a structural panel  10  and receives a standard electrical extension cord ( FIG. 10F ), whereas in further embodiments, the input connector  99  is a power distribution connector that provides a distribution interface to direct electrical power to various loads or other structural panels  10  ( FIG. 10E ). The input connector  99  may comprise an interconnection connector among different structural panels (e.g., an interpanel connector of an interpanel connector system  94 ) ( FIG. 10G ). 
     With reference to  FIG. 10G , various input connectors  99  may be implemented. For instance, structural panels  10  may be interconnected by a MX150L™ Industrial Sealed Connector System available from Molex Incorporated of Lisle, Ill. (interpanel connector system  94 ). As depicted in  FIG. 10G , an interpanel connector system  94  may comprise an input connector  99  comprising a plug  101  with at least one male terminal  102 . The plug  101  may be associated with a first structural panel. Another input connector  99  comprising a receptacle  104  with at least one female terminal  103  may be associated with a second structural panel. When the structural panels are joined together, the input connectors  99  of the interpanel connector system  94  may be in electrical continuity, so that one or more electrical circuit is continued between the panels. An at least 10-circuit plug  101  and receptacle  104  may be implemented and may be configured for 12-AWG terminals. Electrical connectivity between structural panels can be internally either vertical or horizontal. However, other connectors and terminals may be implemented as desired. 
     Having discussed various aspects of a demountable structure system  2 , specific attention is directed to the structural panel  10  and its various features and elements in certain exemplary embodiments. With emphasis on  FIGS. 2 and 3A , a structural panel  10  may have a panel shape (discussed further herein) and may comprise one or more joining member(s)  20 , joining edge(s)  30 , finish panel attachment point(s)  40 , and may have an internal structure  50 . 
     In various embodiments, the structural panel  10  may have differing lengths, heights, and thicknesses. For example, the height may be four feet, or eight feet, or nine feet. In further embodiments, the height may twenty-four feet, or may be any desired height, such as six feet, ten feet, twelve feet, fourteen feet, sixteen feet, eighteen feet, twenty feet, or twenty-two feet, or any desired height. Moreover, the length may be four feet in some embodiments. In further embodiments, the length may be any even number of feet, although length may still further be any desired size. For example, a structural panel  10  may comprise a four feet by eight feet panel, although alternative sizes may be contemplated. Structural panel  10  may also have varying thicknesses. The thickness may be three and five-eighths inches, although any desired thickness may be contemplated. 
     Returning attention to  FIG. 2 , a structural panel  10  may comprise a joining member  20 . Several joining members  20  may be arranged around the sides of the structural panel  10 . Joining member  20  may comprise a cam-lock, or may comprise a cam-lock receptacle, or may comprise any apparatus by which a structural panel  10  may be joined to another structural panel  10 . Joining members  20  may be arranged around the edges of the structural panel  10 , such as along the joining edges  30  (discussed further herein). The joining members  20  of the structural panel  10  are selectably engagable with the joining members  20  of another structural panel  10 . In this manner, structural panels  10  may be selectably joined and separated, as desired. In various embodiments, two joining members  20  are disposed along the joining edge  30  of the structural panel  10 —one near each opposite end of the joining edge  30 . In further embodiments, one or more additional joining member(s)  20  is disposed along the joining edge  30  of the structural panel  10 , such as evenly spaced along the length of the joining edge  30 , or centered on the joining edge  30 , or disposed proximate to areas of concentrated load, such as near a concentration of weight supported by the structural panel(s)  10 . 
     Continuing with reference to  FIG. 2  and with additional reference to  FIGS. 1, 4C, and 4F , the structural panel  10  may comprise a joining edge  30 . The joining edge  30  comprises one or more face(s) of a structural panel  10  oriented to abut a corresponding face of one or more additional structural panel(s)  10 , so that the structural panels  10  may be connected together. For example, the joining edge  30  may further comprise grooves and bosses, as will be discussed further below, to facilitate the connection of structural panels  10  together. The joining edge  30  may be positioned around a perimeter of the structural panel  10 , such as illustrated in  FIG. 4C  (see boss edge  31 ), or may be positioned near the edge of a face of the structural panel  10 , such as illustrated in  FIG. 4F , (see boss receiving edge  32 ). The structural panel  10  may comprise a number of joining edges  30 , and the joining edges  30  may be positioned differently, depending on the desired arrangement of structural panels  10  in the demountable structure system  2  ( FIG. 1 ). 
     With reference to  FIGS. 3A-B , the structural panel  10  may further comprise an internal structure  50 . The internal structure  50  may be an arrangement of panels, voids, and equipment inside the structural panel  10 . For instance, the internal structure  50  may comprise an inner panel  51 , an internal pocket  52 , and an outer panel  53 . Stated differently, the structural panel  10  may comprise an internal structure  50 , the internal structure  50  defined by an inner panel  51  parallel to an outer panel  53 , and spaced away from the outer panel  53  to form an internal pocket  52 . As such, the structural panel  10  may be hollow. In further embodiments, the internal structure  50  may comprise a ballast system  100  whereby the structural panel  10  is weighed down to reduce undesired movement. 
     Turning now to  FIG. 2  and  FIGS. 6A-B , and  FIGS. 6E-F , the structural panel  10  may also comprise finish panel attachment points  40 . Finish panel attachment points  40  may comprise a bracket, clip, or other apparatus whereby the finish panel  60  may be joined to the structural panel  10 . Finish panel attachment points  40  may be spaced across one or more face(s), such as an interior face, of the structural panel  10 . Finish panel attachment points  40  may be spaced across an exterior face of the structural panel  10  as desired. Any number, orientation, or spacing of finish panel attachment points  40  may be contemplated to enable a desired arrangement of finish panels  60 . In various embodiments, structural panel  10  has nine finish panel attachment points  40  for each finish panel  60  desired to be attached. With further reference to  FIGS. 6E and 6F , structural panel  10  may have six finish panel attachment points  40  for each finish panel  60  desired to be attached. 
     Furthermore, finish panel attachment points  40  may comprise mounting brackets  41 . Mounting brackets  41  may comprise a substantially “Z” shaped piece of material (e.g., a “Z-clip”), such as a metal extrusion. In further embodiments, finish panel attachment points  40  may comprise a bracket, clip, or other apparatus whereby a finish panel  60 , or another desired fixture, panel, or apparatus may be joined to the structural panel  10 . Furthermore, different finish panel attachment points  40  may comprise different attachment mechanisms, for example, some may be mounting brackets  41  comprising Z-clips, while others may comprise a bracket, clip, or other apparatus. In various embodiments, with reference to  FIGS. 6E and 6F , a finish panel attachment points  40  may comprise mounting brackets  41  comprising about ten inch (about 25.4 cm) long mounting brackets. 
     The finish panel  60  may also comprise mounting brackets  41 . As with the structural panel  10 , the finish panel  60  may have mounting brackets  41  that comprise a substantially “Z” shaped piece of material (e.g., a “Z-clip”), such as a metal extrusion. Mounting brackets  41  may comprise a bracket, clip, or other apparatus whereby the finish panel  60  may be joined to the structural panel  10 . Mounting brackets  41  are arranged to interface with the finish panel attachment point  40  of the structural panel  10 . As such, the finish panel attachment point  40  of the structural panel  10  may comprise a corresponding mounting bracket  41 , oriented to interlock with the mounting bracket  41  attached to the finish panel  60 . Notably, the finish panel  60  may comprise mounting brackets  41  of different size than the mounting brackets  41  of the finish panel attachment points  40 . For instance, a finish panel  60  may have two about ten inch (about 25.4 cm) long mounting brackets  41  disposed toward the top edge of the finish panel  60  and four about 1½ inch (about 3.8 cm) long mounting brackets disposed below these. Thus, a finish panel may comprise mounting brackets  41  comprising mounting brackets  41  of different sizes than the those mounting brackets  41  of the finish panel  60 . In this manner, the finish panels  60  may be more readily aligned and adjusted in position relative to each other and to the structural panel(s)  10 . 
     Mounting brackets  41  may be spaced across one or more face(s) of the finish panel  60 . Any number, orientation, or spacing of mounting brackets  41  may be contemplated as desired to enable the desired arrangement of finish panels  60 , in view of the corresponding arrangement of finish panel attachment points  40  of the structural panels  10 . In various embodiments, finish panel  60  comprises nine mounting brackets  41 . Notably in other embodiments, there is not a one-to-one correspondence between the mounting brackets  41  of the finish panel  60 , and the finish panel attachment points  40  of the structural panel  10 . As such, one finish panel  60  may span more than one structural panel  10  and may be attached to more than one structural panel  10 . 
     Now, with attention to  FIGS. 1, 7A -E,  8 A-D, and  9 A-E, the event tent comprising of structural panel system  2  may comprise the roof system  70 . The roof system  70  may be a tent style roof system or a rigid tent style roof system such as illustrated in  FIGS. 8A-D . For instance, the roof may comprise a variety of shapes. A tent style roof system or a rigid tent style roof system may be a pyramid roof ( FIG. 8A ), a dome roof ( FIG. 8B ), a staggered triangle roof ( FIG. 8C ), or a louvered panel roof ( FIG. 8D ), among others. With reference to  FIG. 8A , a pyramid roof may comprise a single vertical peak and tapering triangular faces extending to each corner of the demountable structure system  2 . With reference to  FIG. 8B , a dome roof may comprise a semispherical canopy. A sectional plane of the dome roof may comprise a substantially circular profile near the peak of the roof, and may progressively transform into a substantially more rectangular profile approaching the base of the roof and extending to each corner of the demountable structure system  2 . With reference to  FIG. 8C , a staggered triangle roof may comprise multiple peaks or asymmetrical peaks extending in a first direction and spaced in a perpendicular direction along the profile of the demountable structure system  2  and may extend beyond structure to create an extension of canopy beyond base of unit  18  &amp;  19 . Finally, with reference to  FIG. 8D , a louvered panel roof may comprise a series of substantially planar panels extending upwardly away from the demountable structure system  2  and spaced along the profile of the demountable structure system  2 . In some embodiments, the louvered panel roof may be adjustable, so that the angle of the panels may be adjusted up and down so that the louvered panel roof may be substantially more open, or substantially more closed, as desired. 
     Having discussed various aspects of a demountable structure system  2 , attention is now directed to  FIGS. 1, 2  and  FIG. 4C-D , and to various aspects of the joining member  20 . The joining member  20  may comprise a cam  21  (see  FIG. 4C ), and/or a cam receiver  22  (see  FIG. 4D ). For example, a cam  21  may comprise a fastening mechanism having a curved or hook shaped member extending outwardly from the joining edge  30  of the structural panel  10 . The cam  21  may be rotatable about an axis, so that the curved or hook shaped member may engage with a cam receiver  22  such as associated with the joining member  20  of an adjacent structural panel  10 . The cam  21  may further translate substantially normal to the face of the joining edge  30  to draw the cam receiver  22  nearer to the joining edge  30  of the structural panel  10 . In further examples, the cam receiver  22  may comprise an aperture disposed in the joining edge  30  of the structural panel  10 , and corresponding in location to the cam  21  such as associated with the joining member  20  of an adjacent structural panel  10 . In this manner, two structural panels  10  may be selectably joined together, and loaded in compression along their joining edges  30 . 
     Continuing in reference to  FIGS. 1, 2, 4C -D and with additional reference to  FIGS. 5A-B , the joining edge  30  may comprise a boss edge  31  or a boss receiving edge  32 . A boss edge  31  may comprise two grooves  33  and  36 , and a boss  34  disposed between the grooves  33  and  36 . The grooves  33  and  36  each may comprise a channel running along the length of the joining edge  30  of the structural panel  10 . The boss edge  31  may further comprise sound dampening material  35  disposed one or more of the grooves  33 ,  36 . The boss  34  may comprise a raised portion running along the length of the joining edge  30  of the structural panel  10 . A boss receiving edge  32  may comprise two bosses  37  and  39 , and a groove  38  disposed between the bosses  37 ,  39 . Similarly, the boss receiving edge  32  may further comprise sound dampening material  35  disposed the groove  38 . The boss receiving edge  32  may comprise a reciprocal profile of the boss edge  31 , so that when the boss receiving edge  32  of one structural panel  10  and the boss edge  31  of another structural panel  10  are placed together, each boss may correspond to a groove, so that the structural panels  10  interlock. 
     Furthermore, as the boss edge  31  and the boss receiving edge  32  interlock, the sound dampening material  35  may substantially acoustically seal the gap between the boss edge  31  and the boss receiving edge  32 . In various embodiments, the sound dampening material  35  may comprise polypropylene, although any compressible material with desired acoustical absorption properties may be used. The sound dampening material  35  may be 10 millimeter D-shaped hollow edge rubber seal weather stripping. The sound dampening material  35  compresses in response to a compression force exerted by the interlocking boss edge  31  and boss receiving edge  32  further enhancing the acoustical absorption properties. 
     With reference to  FIGS. 1, 2, and 4A -L, the structural panel  10  may have a variety of shapes and configurations. Referring to  FIGS. 2 and 4A , the structural panel  10  may comprise a corner panel  11 . The corner panel  11  may comprise the structural panel  10  having a bend disposed therein, such as a 90-degree bend to form the corner of a structure.

The canvas  61  (not shown, see  FIG. 7A ) comprises a piece of flexible material resting on top of the apex bracket  71  and extending downwardly to the corners of the demountable structure system  2 . In various embodiments the canvas  61  (not shown, see  FIG. 7A ) further rests atop the stringer poles  71 . The canvas  61  (not shown, see  FIG. 7A ) may be fixed at the corners of the demountable structure system  2 , such as by snaps, clips, hook and loop fasteners, poles, or any other appropriate mechanism. 
     While the roof system  70  is illustrated with respect to a pyramid shaped roof ( FIG. 8A ) for tent style roof systems, one may appreciate that by attaching the transverse tension cables  65  at different points, or by incorporating a different number of the elements discussed above, differently shaped roofs may be implemented such as a dome roof ( FIG. 8B ), a staggered triangle roof ( FIG. 8C ), or a louvered panel roof ( FIG. 8D ), among others. 
     With additional attention to  FIGS. 10A-D  a demountable structure system  2  may comprise a roof system  70 , which, as mentioned, may comprise a roof comprising structural panels  10 . In such embodiments, the roof may be arranged according to the principles discussed herein with respect to structural panels  10 . 
     In further embodiments, a roof system  70  may comprise a tent style roof system in part and/or a rigid tent style roof system in part and/or a roof comprising structural panels  10  in part. Thus, various elements of various different embodiments of roof systems  70  may be combined. 
     The various components discussed herein may be assembled in different ways to create different structures. With reference to  FIGS. 1, 2, and 9A -E, the demountable structure system  2  may be assembled and arranged to comprise an enclosed cube  200 . An enclosed cube  200  may comprise different structural panels  10 , connected in a specific arrangement. For instance,  FIGS. 9A-B  depict 3D cross-sections of cam-locking unit placements &amp; wall panel width sizes (corner panels 1′×1′, straight panels 2′ &amp; 4′ and door integrated panels).  FIG. 9C  depicts a 3D cross-section overhead of assembly of walls and cam-locking mechanism alignment.

     The demountable structure system may be manufactured from various materials. The demountable structure system may comprise metal, such as aluminum, titanium, steel, or stainless steel, or composite, ceramic, ceramic matrix composite, plastics, polymers, alloys, austenitic nickel-chromium-based alloys, glass, binder, epoxy, polyester, acrylic, wood, or any material or combination of materials having a desired strength, stiffness, density, weight, or flexibility sufficient to maintain resiliency during use. In various embodiments, various portions of demountable structure systems as disclosed herein are made of different materials or combinations of materials, and/or may comprise coatings. In various embodiments the demountable structure system may be constructed primarily of wood. In further embodiments, the demountable structure system may be constructed primarily from aluminum. In other embodiments, various dimensions of various components of the demountable structure system may vary depending on the material used. For example, a demountable structure system may comprise aluminum components (e.g., structural panels) approximately 1 to 2 inches (about 2.5 to 5 cm) wider than a similar demountable structure system comprising wooden components (e.g., structural panels). 
     In various embodiments, demountable structure systems  2  may comprise multiple materials, or any material configuration suitable to enhance or reinforce the resiliency and/or support of the system when subjected to wear in an operating environment or to satisfy other desired weight, size, electromagnetic, chemical, physical, or biological properties, for example nonreactivity, light weight, load capacity, and heat tolerance. 
     Benefits, other advantages, and solutions to problems have been described herein with regard to specific embodiments. Furthermore, the connecting lines shown in the various figures contained herein are intended to represent exemplary functional relationships and/or physical couplings between the various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in a practical system. However, the benefits, advantages, solutions to problems, and any elements that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as critical, required, or essential features or elements of the inventions. The scope of the inventions is accordingly to be limited by nothing other than the appended claims, in which reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more.” Moreover, where a phrase similar to “at least one of A, B, or C” is used in the claims, it is intended that the phrase be interpreted to mean that A alone may be present in an embodiment, B alone may be present in an embodiment, C alone may be present in an embodiment, or that any combination of the elements A, B and C may be present in a single embodiment; for example, A and B, A and C, B and C, or A and B and C. 
     Systems, methods and apparatus are provided herein. In the detailed description herein, references to “various embodiments”, “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may comprise a particular feature, structure, or characteristic, but every embodiment may not necessarily comprise the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. After reading the description, it will be apparent to one skilled in the relevant art(s) how to implement the disclosure in alternative embodiments. 
     Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. No claim element herein is to be construed under the provisions of 35 U.S.C. 112(f), unless the element is expressly recited using the phrase “means for.” As used herein, the terms “comprises”, comprising”, or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not comprise only those elements but may comprise other elements not expressly listed or inherent to such process, method, article, or apparatus.
