## Title
Universal panels and structures comprised of the same

## Abstract

Embodiments of the present technology provides universal panels and structures made from the same. The panels are formed using specific ratios for width and length of the panels, which are related to ratios of aperture spacings for the panels. These ratios are used to ensure that panels can be used in a universal manner to form walls, roofs, and doors. Additionally, the universality of the panels reduces the likelihood that installation errors will occur when building structures with these panels. Installation errors can deleteriously affect the structural integrity of the the resulting structure.

DETAILED DESCRIPTION
Generally, the present technology is directed to universal panels that can be arranged in various configurations to form walls, enclosures and/or other similar structures. In some instances, a plurality universal panels are arranged to form a storm shelter. Advantageously, the universality of the panel construction ensures that shelters are constructed correctly and consistently, reducing the likelihood that structural failures will occur due to installation errors. For example, storm shelters manufactured from components that are not universal in nature may fail when components are installed improperly due to manufacturing discrepancies with the components such as misaligned bolt holes and/or poorly fitting components that are supposed to mate together. Additionally, installation errors can reduce the structural integrity of the storm shelter. For example, if certain bolt holes that are supposed to align are misaligned during installation, an installer may attempt to drill new bolt holes or modify the existing holes. These types of modifications can deleteriously impact the strength of the structure by creating potential failure points.
Advantageously, the present technology provides a panel that is universal with respect to the creation of structures therefrom. A plurality of panels of the present technology can be joined together side edge to side edge irrespective of whether the panels are oriented in an upright configuration or a downward configuration, relative to one another. The panels can also be used to create a roof and/or door for the structure, without any structural modification to the panel. Indeed, the universality of the panels provides for installation in a foolproof manner, ensuring the strength and structural integrity of the resulting structure.
Referring now to FIG. 1, an example structure 100 is illustrated. The structure 100 is comprised of a plurality of panels, such as panel 102. The plurality of panels are attached together to form the structure 100, which in this example is a safe room such as a tornado shelter. In some embodiments, the panels are designed such that the structure 100 is capable of withstanding the impact force of debris from an F-5 tornado.
Referring now to FIGS. 2A, 2B, and 2D, the panel 102 is illustrated in greater detail. The panel 102 is constructed from a sheet of material 104 such as metal, which is laser or machine cut to specified dimensions. The panel 102 can be constructed from an alloy or a composite material such as carbon fiber or other sufficiently strong materials. The required strength of materials is based upon the ultimate use of the panel and/or structure. For example, if the desired use is storm protection, the material chosen needs to withstand certain forces.
The sheet of material 104 is cut to create flange panels, such as flange panel 105 that are used to form a top flange 106, a bottom flange 108, a first edge flange 110 and a second edge flange 112.
The sheet of material 104 is bent along bend lines 104A-D to fold the flange panels and form the top flange 106, the bottom flange 108, the first edge flange 110 and the second edge flange 112.
After creation of the flanges, the panel 102 comprises an overall length L and an overall width W. The length is measured from a top end 124 to a bottom end 126. The width W is measured from a first edge 128A of the top end 124 to a second edge 128B of the top end 124. The width of the panel 102 is also consistent down to the bottom end 126 of the panel 102, extending between a first edge 130A of the bottom end 126 to a second edge 130B of the bottom end 126.
In one embodiment, a ratio between the length L and width W is maintained to ensure that panels can be used in a universal manner. For example, the width W is one fifth of overall length L. In one example, the overall length L is eighty inches and the width W is sixteen inches.
As will be described in greater detail below, the ratio between the length L and width W of the panel, as well as the spacing of apertures on the flanges 106, 108, 110, and 112 ensures that panels can be used universally to form walls, a roof, and/or a door.
Each of the flanges 106, 108, 110, and 112 is provided with apertures that are configured to receive bolts for joining a respective flange to another flange of another panel, as will be described in greater detail below.
In FIG. 2C, the first edge flange 110 comprises a plurality of apertures 114 located in spaced apart relation along a first plane of symmetry X of the panel 102. Similarly, the second edge flange 112 comprises a plurality of apertures 116 that are located in spaced apart relation along a second plane of symmetry Y of the panel 102. In some embodiments, the plurality of apertures 114 associated with the first plane of symmetry X and the plurality of apertures 116 associated with the second plane of symmetry Y are aligned with one another.
According to some embodiments, a first 120 of the plurality of apertures 114 of the first edge flange 110 is located at a distance D1 that is approximately one twentieth of the length L of the panel 102 from the top end 124 of the panel 102.
A last 134 of the plurality of apertures 114 of the first edge flange 110 is located at a distance D2 that is approximately one twentieth of the length L of the panel 102 from the bottom end 126 of the panel 102. For example, if the overall length L of the panel 102 is 80 inches, D1 for the first 120 of the plurality of apertures 114 is four inches. Again, D1 is measured from the top end 124 of the panel 102. This is a second ratio for the panel 102. Thus, the panel 102 has two unique ratios that allow the panel 102 to be used in a universal manner, where the width W is one fifth of the length L of the panel and the distances D1 and D2 are one twentieth of the length L of the panel 102 (where D1=D2).
Thus, D2 of the last 134 of the plurality of apertures 114 is also four inches, but D2 is measured from the bottom end 126 of the panel 102.
Remaining ones of the plurality of apertures 114 are spaced apart from one another at eight inches. Apertures that are adjacent to the first 120 and last 134 are also spaced at a distance of eight inches from the first 120 and last 134 apertures.
A third unique ratio is used for the remaining ones of the plurality of apertures, which is one-tenth the overall length L of the panel 102.
FIG. 2E illustrates the spacing of a plurality of apertures 107A-J for an example edge flange of a panel 102. Apertures 107A and 107J are located at distances that are one twentieth of the overall length L of the panel 102. These distances are measured relative to the nearest end edge. The remaining apertures 107B-I are spaced equidistantly from one another as well as from apertures 107A and 107J. For example, aperture 107B is located at 12 inches from the upper end of the panel 102 and eight inches from aperture 107A. Aperture 107C is located eight inches from aperture 107B. Aperture 107D is located eight inches from aperture 107C, while aperture 107E is located eight inches from aperture 107D. Aperture 107F is located eight inches from aperture 107E, while aperture 107G is located eight inches from aperture 107F. Aperture 107H is located eight inches from aperture 107G, while aperture 107I is located eight inches from aperture 107H. Aperture 107I is located at twelve inches from the bottom end of the panel 102 and eight inches from aperture 107J.
As mentioned above, the spacing of apertures is identical between the first and second edge flanges of a panel 102.
The apertures 116 of the second edge flange 112 are laid out identically to the apertures 114 of the first edge flange 110. A first 138 of the plurality of apertures 116 of the second edge flange 112 is located at a distance D2 that is approximately one twentieth of the length L of the panel 102 from the top end 124 of the panel 102.
A last 140 of the plurality of apertures 116 of the second edge flange 112 is located at a distance D2 that is approximately one twentieth of the length L of the panel 102 from the bottom end 126 of the panel 102.
It will be understood that D1 is identical to D2, ensuring that the first 120 and last 134 of the plurality of apertures 114 of the first edge flange 110 are aligned with the first 138 and last 140 of the plurality of apertures 116 of the second edge flange 112, respectively.
Referring now to FIG. 3A, it will be understood that the alignment of apertures between first and second edge flanges of a panel ensure that when two panels A and B are joined together, the apertures of the edge flanges of the panels A and B align.
Broadly stated, a plurality of panels can be arranged side-to-side in such a way that the plurality of apertures of the second edge flange of a panel of the plurality of panels are aligned with the plurality of apertures of the first edge flange of an adjacent panel. A single panel can be joined to two other panels, one on the first edge flange of the single panel and the other on the second edge flange of the single panel.
For example, the first edge flange A1 of panel A is mated with the second edge flange B2 of panel B.
Again, the apertures of the panels align irrespective of whether a first panel is oriented upright (top end pointed up) and a second panel is oriented downwardly (top end pointed downwardly) such that cover plate 174 of panel B is below vent holes 172 of panel A. Also, alignment of the apertures between a first and a second panel is unaffected when the first panel A is oriented with its flanges AA facing outwardly and the second panel B is oriented with its flanges BB facing inwardly, as in FIG. 3B. To be sure, as long as the first and second panels are brought together such that at least one of the edge flanges touches an edge flange of the other panel, the panels can be secured together using fasteners.
Example fasteners 142 are illustrated in FIG. 3A. The fastener 142 can comprise a bolt with a nut. The head of the bolt is positioned on one flange of one panel, while the nut is positioned on the flange of the other panel.
The use of bolts as fasteners is advantageous at least because the shelter 100 can be quickly disassembled if needed. Also, the size of the structure 100 can be changed by adding or subtracting panels, as needed. The use of bolts as fasteners allows for resizing of the structure 100 without the need to completely dismantle and/or rebuild the structure. For example, if the structure is comprised of four walls, the structure can be resized by adding another panel to each wall.
Referring now to FIG. 4, a top down view of the structure 100 of FIG. 1 is illustrated, with a roof of the structure 102 removed. The structure 100 has four walls 146A-D, where each wall is constructed from a plurality of panels, such as panel 102 of FIGS. 2A-D. Each wall is coupled to two adjacent walls using a channel. For example, wall 146A is attached to wall 146B using a channel 150, while wall 146A is attached to wall 146D using a channel 152. The L-shaped channels form the four corners of the structure 100.
In FIG. 5, a channel, such as channel 150 comprises an L-shaped channel that comprises plates 154A and 154B that each comprise apertures 156A and 156B, respectively. The apertures 156A and 156B are spaced identically to the apertures of the first and second edge flanges of a panel of the structure 100. By way of example, the plate 154A of the L-shaped channel 150 mates with an edge flange of the wall 146A. The plate 156A of the L-shaped channel 150 mates with an edge flange of the wall 146B.
Referring to FIG. 2G, the top flange 106 and bottom flange 108 of each panel 102 includes a pair of apertures. For example, top flange 106 comprises apertures 160A and 160B, while bottom flange 108 comprises apertures 162A and 162B.
The aperture 160A of the pair of apertures is spaced apart from the first edge 128A of the top flange 106 at a distance D3 that is approximately one twentieth of the length L of the panel 102. The aperture 160B of the pair of apertures is spaced apart from the second edge 128B of the top flange 106 at a distance D4 that is approximately one twentieth of the length L of the panel 102. It will be understood that D1, D2, D3, and D4 are identical in size such that D1=D2=D3=D4, where D1 is approximately 1/20 of the overall length L of the panel 102.
The apertures 162A and 162B are located on the bottom flange 108 at distances D5 and D6, respectively. These distances D5 and D6 are also identical in size to D1, such that D1=D2=D3=D4=D5=D6.
It will be understood that the spacing of the apertures 160A and 160B of the top flange 106 will create an aperture spacing that is identical to the spacing of apertures of the edge flanges, such as first edge flange 110 and second edge flange 112 of the panel 102.
In FIG. 2F, a plurality of panels is illustrated as joined together to form a wall. The spacing of the pair of apertures of each top flange is one twentieth of the length L of the panel from their respective edges. When multiple panels are joined, the first and last apertures are located at one twentieth of the length L of the panel from the nearest edge surface, while apertures between the first and last apertures are spaced at one tenth of the length L of the panel (between adjacent apertures).
More specifically, the spacing of a plurality of apertures 109A-J for a plurality of panels that have been joined together to form a wall 109 is illustrated. Apertures 109A and 109J are located at distances that are one twentieth of the overall length L of a panel of the wall 109. These distances are measured relative to the nearest end edge. The remaining apertures 109B-I are spaced equidistantly from one another as well as from apertures 109A and 109J. For example, aperture 109B is located at 12 inches from a first edge 111 of the wall 109 and eight inches from aperture 109A. Aperture 109C is located eight inches from aperture 109B. Aperture 109D is located eight inches from aperture 109C, while aperture 109E is located eight inches from aperture 109D. Aperture 109F is located eight inches from aperture 109E, while aperture 109G is located eight inches from aperture 109F. Aperture 109H is located eight inches from aperture 109G, while aperture 109I is located eight inches from aperture 109H. Aperture 109I is located at twelve inches from a second edge 113 of the wall 109 and eight inches from aperture 109J.
Referring collectively to FIGS. 2E and 2F, the apertures of 107A-J of the first flange 110 align with the apertures 109A-J of the wall 109. Thus, a wall formed from a plurality of panels can be mated with a single panel that runs perpendicular to the wall. The single panel is often associated with another wall, such as a roof or floor.
Referring now to FIGS. 6A and 6B, according to some embodiments, the structure 100 comprises a roof 166 that, just like the walls 146A-D, is comprised of a plurality of panels, such as panel 102.
The roof 166 panels define an outer edge of apertures 168. This outer edge of apertures 168 is formed from apertures of top and edge flanges of the panels that comprise the roof 166. Two portions of the outer edge of apertures 168 are comprised of edge flange apertures, and the other two portions of the outer edge of apertures 168 are comprised of top flange apertures.
The enclosure formed by walls 146A-D defines an upper edge of apertures 170. The upper edge of apertures 170 is formed entirely from apertures of top flanges of the panels of the walls 146A-D.
When the roof 166 is mated with the walls 146A-D the outer edge of apertures 168 of the roof 166 and the upper edge of apertures 170 of the walls 146A-D align. L-shaped channels (such as channels 150 and 152 of FIG. 5) are used to join the roof 166 to the walls 146A-D. Fasteners are used to join the roof 166 to walls 146A-D using the L-shaped channels.
Returning briefly to FIG. 2A, each panel may comprise vent holes 172 that provide ventilation and exchange of air into the structure 102. A cover plate 174 (FIG. 2B) that prevents wind-blown debris from entering the vent holes 172 can cover the vent holes 172.
FIG. 7 illustrates an example door 176, constructed from a plurality of panels, such as panel 102. The panels are hingedly connected to a portion of a wall. The door 176 is also lockingly couplable to another panel of the wall. The door 176 is provided with sliding J-bolts 178A-C that cooperate with latches 180A-C, respectively, in the adjacent panel. The door 176 can be secured using the J-bolts 178A-C. A secondary lock such as a deadbolt can also be used to secure the door 176.
Referring now to FIG. 8, a portion of an example enclosure 800 is illustrated. The enclosure is fabricated using any of the panels described above, such as panel 802. Walls, such as wall 804, are constructed from a plurality of panels. Whereas in embodiments above, walls are connected or coupled using L-shaped brackets, the walls are joined using an L-shaped corner member. For example, wall 804 and wall 806 are joined using an example L-shaped corner member 808. In contrast with the embodiments above that use L-shaped brackets using fasteners that are accessible from the outside of the enclosure (see FIG. 1), the L-shaped corner members present flanges and apertures that mate with end flanges of end panels of walls 804 and 806.
FIG. 9 illustrates an example top down view of the enclosure 800 with a top wall or panel removed. In this view wall 804 and wall 806 are coupled using an L-shaped corner member 808. Fasteners, such as fastener 810 are used to couple the walls to the L-shaped corner member 808.
In FIG. 10, an example L-shaped corner member 808 is illustrated. The L-shaped corner member 808 comprises a body 812, a first end flange 814, and second end flange 816. Each of the end flanges 814 and 816 comprise a plurality of apertures, such as aperture 818. The spacing of the apertures conforms to any of the spacing patterns described throughout this disclosure.
The end flanges 814 and 816 are positioned to connect two walls (such as walls 804 and 806 in FIGS. 8 and 9) together. Thus, fasteners can be installed between L-shaped corner members and two separate panel walls from an interior of the enclosure. This is advantageous when installing the enclosure in an interior space, such underneath a stairway or in a closet. That is, using L-shaped brackets as described in other embodiments may not be advantageous in instances where installers cannot access an outside of the enclosure. In one embodiment, the L-shaped corner member 808 can be fabricated from one of the panels described above through bending the universal panel to form a right angle about its midline M. Other shaped and configured corner members are also contemplated. For example, FIG. 11 illustrates another example panel 900 that includes a first side 902 that is longer than a second side 904. In some embodiments, an upper flange (such as upper flange 903 of first side 902) of either side 902 or 904 can comprise apertures such as aperture 906 that can serve as alignment and securement points for joining top wall panels thereto.
