Title: Bracket for angled ceiling panels and ceiling panel system

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority of U.S. Provisional Patent Application No. 63/279,910, filed Nov. 16, 2021, which is hereby incorporated herein by reference in its entirety. 
    
    
     BACKGROUND OF THE DISCLOSURE 
     1. Field of the Disclosure 
     The present disclosure relates generally to ceiling panel brackets, for example, suitable for forming a ceiling surface by supporting a plurality of ceiling panels. The present disclosure relates more particularly to a carrier for supporting ceiling panels at an angle. 
     2. Technical Background 
     Panels are convenient and effective for constructing architectural surfaces. The panels may be pre-fabricated and shipped to the construction location, allowing for efficient installation that covers a large surface area. If damaged, the panels can be wholly replaced, rather than requiring a custom repair of the architectural surface. In some cases, the panels can be removed to provide access to the area behind the panels. 
     Panels that are used to form an architectural surface, such as a ceiling, are often supported by a structural grid that holds the panels in place. This allows flexibility in the design of the panels, because the supporting grid provides the structural integrity needed for the architectural surface, thereby allowing the design of the panels to address aesthetic and acoustic requirements of the ceiling system. The panels are typically held in a row or an array to provide an attractive ceiling surface. Panels are often oriented either parallel to the grid so as to form a planar surface, or perpendicular to the grid, such as ceiling baffles. Other configurations are possible, but these are frequently achieved by either customizing the ceiling grid or by hanging the panels with wire from the grid at different lengths. While such building surface structures may be aesthetically interesting, they require the use of various custom configurations and complex installation, thereby increasing installation complexity and costs. 
     The present inventors have recognized that a ceiling system that allows for an alternative ceiling aesthetic without adding significant complexity in installation would be attractive to architects and builders. 
     SUMMARY OF THE DISCLOSURE 
     In one aspect, the present disclosure provides a bracket configured to couple a ceiling panel to a ceiling grid, the bracket comprising:
         a support arm configured to extend over a first flange of a T-beam of the ceiling grid;   an attachment wall extending up from the support arm, the attachment wall being configured to be secured to a web of the T-beam;   a leg extending down from the support arm so as to hang below the T-beam; and   a foot coupled to the leg and configured to be attached to the ceiling panel, the foot being disposed at a first angle with respect to the support arm so as to hold the ceiling panel at an angle to the ceiling grid.

     DETAILED DESCRIPTION 
     As described above, the present inventors have noted that a conventional ceiling system that allows for an alternative ceiling aesthetic without adding significant complexity in installation would be attractive to architects and builders. 
     Accordingly, one aspect of the disclosure is a bracket configured to couple a ceiling panel to a ceiling grid. The bracket includes a support arm configured to extend over a first flange of a grid beam. An attachment wall extends up from the support arm and is configured to be secured to a web of the grid beam. On the other hand, a leg extends down from the support arm so as to hang below the grid beam. A foot is coupled to the leg and is configured to be attached to the ceiling panel. The foot is disposed at a first angle with respect to the support arm so as to hold the ceiling panel at an angle to the ceiling grid. 
     Such a bracket is shown in perspective view in  FIG.  1    and a side view in  FIG.  2   . Bracket  100  includes a support arm  110  configured to extend over a first flange of a grid beam, as explained further below. An attachment wall  120  extends up from support arm  110  and is configured to be secured to a web of the grid beam. Opposite attachment wall  120 , a leg  130  extends down from support arm  110  so as to hang below the grid beam. A foot  150  is coupled to leg  130  and is configured to be attached to a ceiling panel. As shown in  FIG.  2   , foot  150  is disposed at a first angle α with respect to support arm  110  in order to hold the ceiling panel at an angle to the ceiling grid, as explained in more detail below.  FIG.  3    shows a front view of bracket  100  secured to a grid beam  160 . In particular, support arm  110  extends over a first flange  162  of grid beam  160  and attachment wall  120  is secured against web  166 . 
     In another aspect, the disclosure provides a ceiling system that includes a ceiling grid with a first grid beam, a first bracket coupled to the first grid beam, and a first ceiling panel attached to the first bracket. The grid beam includes a web and a first flange extending laterally from the web. A first bracket according to the disclosure is coupled to the first grid beam. A first ceiling panel is coupled to the foot of the first bracket. The first ceiling panel has a first face and a second face opposite the first face. Moreover, the first ceiling panel extends along a length from a first end to a second end and extends across a width from a first side to a second side. 
     A portion of such a ceiling system is shown in  FIGS.  4  and  5   . Ceiling system  180  includes first grid beam  160  with first bracket  100  coupled thereto. In particular, bracket  100  is positioned with support arm  110  and attachment wall  120  adjacent to first grid beam  160 . Ceiling system  180  also includes a first ceiling panel  170  coupled to the foot  150  of bracket  100 . Ceiling panel  170  extends along a length (indicated by direction  172 ) from a first end to a second end and extends across a width  174  from a first side  176  to a second side  178 . 
     As shown in  FIG.  1   , support arm  110  of bracket  100  has a depth  112  that extends from an inner edge  116  to an outer edge  118  and a width  114  that is oriented so as to extend along the longitudinal direction of the grid beam when bracket  100  is attached thereto, as shown in  FIG.  4   . Attachment wall  120  extends upward from the inner edge  116  of support arm  110  over a height  122 , and also has a width  124  that extends in the longitudinal direction of the grid beam. Leg  130  extends down from outer edge  118  and has a width  134 . Because of the angle of foot  150 , leg  130  is longer on one side than the other. Foot  150  extends away from leg  130  along a length  152  and has a width  154  that is runs perpendicular to length  152 . 
     In certain embodiments of the ceiling system as otherwise described herein, the first grid beam is a T-beam. For example, as shown in  FIGS.  3  and  4   , first grid beam  160  is in the form of a T-beam that includes web  166  and first flange  162  extending laterally from web  166 . As shown in  FIG.  3   , a second flange  164  also extends from web  166  opposite first flange  162 . Further, first grid beam  160  is formed from a bent metal sheet that loops at the top to form a bulb  168 , which provides structural stability to first grid beam  160 . In other embodiments, the grid beams may have a different configuration, such as an extruded T-beam, with or without a bulb at the peak. Moreover, in some embodiments, the grid beams have a different shape that is not a T-beam, such as an I-beam or channel configuration. 
     In certain embodiments of the ceiling system as otherwise described herein, the attachment wall of the first bracket is secured against the web of the first grid beam. For example, as shown in  FIG.  4   , the attachment wall  120  of bracket  100  is attached against one side of web  166  of first grid beam  160 . In ceiling system  180 , attachment wall  120  is fastened to web  166  using a single fastener. In other embodiments, the attachment wall of the bracket is secured to the web of the grid beam using two or more fasteners. Further, in other embodiments, the attachment wall is bonded or adhered to the web of the grid beam. Still, in other embodiments, the grid beam and attachment wall may have interlocking configurations. For example, in some embodiments, the web may include clips, hooks, or apertures, and the attachment wall may include clips, hooks or apertures that mate with the corresponding structure of the web. 
     In certain embodiments of the ceiling system as otherwise described herein, at least a portion of the support arm of the first bracket is supported by the first flange of the first grid beam. For example, as shown in  FIG.  3   , support arm  110  rests on first flange  162  such that first flange  162  provides vertical support to bracket  100 . In some embodiments, the support arm is substantially parallel with the first flange and is supported across the depth of the flange from the outer edge to the web. In other embodiments, only a portion of the support arm is supported by the first flange of the grid member. For example, in some embodiments, the support arm is only supported along the outer edge of the flange of the grid beam. Still in other embodiments, the support arm extends over the flange of the grid beam without making contact with the flange. For example, in some embodiments, the attachment wall of the bracket is secured to the grid beam such that the support arm extends over the flange but is spaced therefrom. 
     In certain embodiments of the ceiling system as otherwise described herein, the foot of the first bracket is secured against the first side of the first ceiling panel. For example, as shown in  FIG.  4   , foot  150  of bracket  100  is attached to the first side  176  along the top of ceiling panel  170 . Accordingly, ceiling panel  170  extends along its width  174  away from bracket  100  and the ceiling grid. The location of foot  150  attached to first side  176  can help obscure both foot  150  and the rest of bracket  100  from the view of any positioned below the ceiling grid. 
     As shown in  FIG.  5   , with foot  150  of bracket  100  attached along first side  176  of ceiling panel  170 , ceiling panel  170  forms an angle β with respect to the ceiling grid that is a complementary angle to the angle α of foot  150 . For example, in embodiments where the angle between the foot and the support arm is 30 degrees, and the foot is attached to the upper side of the ceiling panel, the ceiling panel may be disposed at an opposing angle of 60 degrees. On the other hand, in other embodiments, the foot is secured to the face of the ceiling panel, rather than the side. Accordingly, in such embodiments, the angle between the foot and the support arm may be the same as the angle between the ceiling panel and the support arm. 
     In some embodiments, the angle between the support arm and the foot of the bracket is at least 5 degrees, e.g., at least 10 degrees, e.g., at least 15 degrees. Further, in some embodiments, the angle between the support arm and the foot is no more than 85 degrees, e.g., no more than 80 degrees, e.g., no more than 75 degrees. For example, in some embodiments, the angle between the support arm and the foot is in a range from 15 degrees to 75 degrees, e.g., 20 degrees, 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees or 70 degrees. 
     In ceiling system  180 , foot  150  is fastened to first ceiling panel  170  using a pair of fasteners, such as screws or bolts. In other embodiments, the foot of the bracket is secured to the first ceiling panel using a single fastener or more than two fasteners. Further, in other embodiments, the foot of the bracket is bonded or adhered to the first ceiling panel. In some embodiments, fasteners that hold the foot to the ceiling panel engage the material forming the outer surface of the ceiling panel. In other embodiments, the fasteners extend through the material that forms the outer surface of the ceiling panel. For example, in some embodiments, the outer surface of the ceiling panel is formed by a shell, and the fasteners pass through the outer shell and are secured on the inside of the shell. For instance, in some embodiments, an internal bracket is disposed inside the outer shell of the ceiling panel. Such an internal bracket may be coupled to the foot of the bracket with the outer shell of the ceiling panel sandwiched between the brackets. Still, in other embodiments, fasteners that hold the ceiling panel to the foot of the bracket may be held in place with washers and nuts positioned inside the outer shell of the ceiling panel. 
     In certain embodiments of the bracket as otherwise described herein, the foot is formed as a flat plate. For example, as shown in  FIGS.  1  through  5   , foot  150  is formed as a flat plate that is configured to lie against the wall along the first side  176  of first ceiling panel  170 . In other embodiments, the foot may have one or more bends. For example, in some embodiments, the foot may have an L-shaped or U-shaped configuration in order to be secured to more than one surface of the ceiling panel. For instance, embodiments with an L-shaped configuration may be configured to be attached to both the first side and one face of the ceiling panel. 
     In certain embodiments of the bracket as otherwise described herein, the support arm is formed as a flat plate. Likewise, in some embodiments, the attachment wall is formed as a flat plate. For example, in bracket  100 , support arm  110  is formed as a flat plate and attachment wall  120  is also formed as a flat plate that extends upward from the inner edge  116  of support arm  110  so as to be perpendicular to support arm  110 . With both the support arm  110  and attachment wall  120  formed as flat plates, the support arm and attachment wall can engage corresponding flat surfaces of the grid beam, as shown in  FIG.  3   . On the other hand, in other embodiments, either or both of the attachment wall and support arm may have a configuration other than a flat plate. For example, these portions of the bracket may be formed as curved plates, wire frames, rods, or other shapes. 
     In certain embodiments of the bracket as otherwise described herein, the support arm and the foot are angled about a lateral axis that is perpendicular to the attachment wall. For example, the angle of foot  150  in bracket  100 , as shown in  FIGS.  2  and  4    is measured about an axis that is perpendicular to the attachment wall and to the web of the grid beam. Accordingly, a ceiling panel attached to the bracket and arranged with its length substantially perpendicular to the grid beam may have the width of its front and rear faces angled with respect to the plane of the ceiling grid. In other embodiments, the foot may be angled with respect to the support arm about a different axis. For example, the foot may be angled about a different axis in order to hold a ceiling panel at an angle where the ceiling panel extends parallel to the first grid beam or diagonally across the first grid beam. 
     In certain embodiments of the bracket as otherwise described herein, the foot is laterally offset from the support arm. For example, as shown in  FIG.  3   , foot  150  extends laterally outward from leg  130  in the opposite direction of support arm  110 , such that foot  150  is laterally offset from support arm  110  in the direction that is perpendicular to grid beam  160 . In other embodiments, such as in  FIGS.  7 - 9    described below, the foot may be at least partially aligned under the support arm. For example, the leg may extend under the support arm, or the foot may project in the opposite direction as that shown in  FIG.  3   , such that the foot extends under the support arm. 
     In certain embodiments of the bracket as otherwise described herein, the support arm, attachment wall, leg, and foot are formed in a single integral piece. For example, in some embodiments, the support arm, attachment wall, leg, and foot are formed from a bent metal sheet. For example, bracket  100 , shown in  FIGS.  1 - 5    is formed from a single cut metal sheet that is bent to form the shape of the bracket. The term metal sheet, as used herein, is not limited to any particular thickness, and may otherwise be referred to as sheet metal, metal plate, or metal foil. In some embodiments, the bracket may include apertures, such as to receive fasteners. Such apertures may be provided in the material of the bracket when it is cut, before or after it is cut, or before or after the material is bent. 
     In certain embodiments of the bracket as otherwise described herein, a width of the support arm is substantially the same as a width of the attachment wall. For example, in bracket  100 , support arm  110  and attachment wall  120  are formed from a rectangular portion of material with a single bend along inner edge  116 . Accordingly, the widths  114 ,  124  of support arm  110  and attachment wall  120  are the same. In other embodiments, the widths of the support arm and attachment wall may be different. For example, in some embodiments the width of the support arm may be greater than the width of the attachment wall so that the grid beam can provide greater vertical support to the support arm. In other embodiments, the width of the attachment wall may be greater than the width of the support arm, so that the connection between the attachment wall and the grid member can be enhanced. 
     In certain embodiments of the bracket as otherwise described herein, a width of the foot is substantially the same as a width of the support arm. For example, in bracket  100 , width  154  of foot  150  is substantially equal to width  114  of support arm  110 . Having the width of the support arm and the foot be similar may allow for a reduction in the amount of material used to form the bracket, as the blanks for a number of brackets can be cut from a single sheet in a row, thereby minimizing wasted material between the cut blanks. On the other hand, the width of the foot may be different from that of the support arm. For example, in some embodiments, the width of the foot may be selected based on the thickness of a ceiling panel that will be held by the bracket. If such a width does not provide an adequate connection to the grid beam, the widths of the support arm and the attachment wall may be larger than the width of the foot, to provide a larger connection area. Likewise, the connection between the foot and the ceiling panel can be increased by increasing the length of the foot without the need to have the foot extend past the edges of the ceiling panel. 
     In certain embodiments of the bracket as otherwise described herein, a width of the leg is less than a width of the foot. For example, in bracket  100 , the width  134  of leg  130  is smaller than the width  154  of foot  150 . This decreased width of leg  130  compared to both foot  150  and the thickness of the attached ceiling panel helps obscure leg  130  from anyone viewing the ceiling system from below. 
     In certain embodiments of the bracket as otherwise described herein, the foot is coupled to the leg at a selectable angle. For example, in some embodiments, the attachment wall, support arm, and leg are part of a grid attachment structure, and the foot is part of a panel attachment structure that is removably coupled to the grid attachment structure so as to form the selectable angle. 
     Such an embodiment is shown in  FIGS.  7  and  8   . Bracket  700 , shown in  FIG.  7   , includes a support arm  710  configured to extend over a first flange of a grid beam, as explained further below. An attachment wall  720  extends up from support arm  710  and is configured to be secured to a web of the grid beam. Opposite attachment wall  720 , a leg  730  extends down from support arm  710  so as to hang below the grid beam. Each of support arm  710 , attachment wall  720 , and leg  730  are part of a grid attachment structure  702  that is configured to be secured to a grid beam. Bracket  700  also includes a panel attachment structure  704  including a foot  750  that is configured to be attached to a ceiling panel. Panel attachment structure  704  is removably coupled to grid attachment structure  702  in order to form the selectable angle. 
       FIG.  8    shows a portion of a ceiling system  780  that uses bracket  700 . Ceiling system  780  includes a first grid beam  760  with a first bracket  700  coupled thereto. In particular, bracket  700  is positioned with attachment wall  720  secured to the web  766  of first grid beam  760 . Support arm  710  extends over the first flange  762  of first grid beam  760  and leg  730  extends down below grid beam  760 . Ceiling system  780  also includes a first ceiling panel  770  coupled to the foot  750  of bracket  700 . Ceiling panel  770  extends across a width  774  from a first side  776  to a second side  778 , and foot  750  is attached to the first side  776  of ceiling panel  770 . The position of foot  750  with respect to leg  730  defines the angle of ceiling panel  770 , as explained in more detail below. 
     In certain embodiments of the bracket as otherwise described herein, the panel attachment structure includes a post extending up from the foot that is coupled to the leg of the grid attachment structure. For example, panel attachment structure  704  of bracket  700  includes a post  756  attached to foot  750 . Post  756  is attached to leg  730  using a pair of fasteners  758  that set the orientation of panel attachment structure  704  and, thus, the angle of foot  750  and ceiling panel  770 . 
     In certain embodiments of the bracket as otherwise described herein, the leg includes a series of apertures for adjusting a position of the post so as to secure the foot at the selectable angle. For example, leg  730  of bracket  700  includes an upper aperture  732  and a series of lower apertures  736 . The post  756  is secured to leg  730  with a fastener  758  that extends through upper aperture  732  and one of the lower apertures  736  in the series of lower apertures. By choosing one of the selectable lower apertures  736  the angle of the post  756  and foot  750  can be selected. While leg  730  of bracket  700  includes a single upper aperture  732  and a series of lower apertures  736 , in other embodiments, the leg of the bracket includes a single lower aperture and a series of upper apertures. By selecting the upper aperture for attachment with the post, the angle of the foot may be selected in a similar manner as with bracket  700 . Further still, in some embodiments, the bracket includes a series of upper apertures and a series of lower apertures. 
     In certain embodiments of the bracket as otherwise described herein, the series of apertures is arranged in an arc. For example, the series of lower apertures  736  of bracket  700  are arranged at various positions along an arc, which allows the post  756  to be set at any of a group of different angles. In leg  730 , the arc of lower apertures  736  extends to either side of the vertical axis. Accordingly, a ceiling panel attached to bracket  700  can be rotated to angles on either side of the vertical axis without rearranging bracket  700  on the grid beam. In other embodiments, the series of apertures are only arranged on one side of the vertical axis. In such a case, the ceiling panel can be angled in the opposite direction by securing the bracket to the grid beam in the opposite direction. Further, in some embodiments, the series of apertures have a symmetrical configuration about the vertical axis. In such a case, the selectable angles can be chosen regardless of the orientation of the bracket on the grid beam. In other embodiments, the apertures on one side of the vertical axis may be at different angles than the apertures on the other side of the vertical axis, such that intermediate angles can be selected by orienting the bracket in the opposite direction on the grid beam. 
     In certain embodiments of the bracket as otherwise described herein, the bracket includes a lateral projection between the support arm and the leg, and the lateral projection is configured to extend under the flange of the grid beam such that the leg is positioned below the grid beam. For example, as shown in  FIG.  7   , bracket  700  includes a lateral projection  738  between support arm  710  and leg  730 . The lateral projection  738  extends down and inward from support arm  710  so as to pass under the first flange  762  of the first grid beam  760 , as shown in  FIG.  8   . The use of lateral projection  738  allows part of foot  750  to be positioned underneath grid beam  760 . 
     While the illustrated embodiment of the lateral projection is included in bracket  700 , which includes a separate grid attachment structure  702  and panel attachment structure  704 , in other embodiments, a lateral projection is included in bracket configurations that are formed as a single piece. 
     In certain embodiments of the bracket as otherwise described herein, the bracket includes a second grid attachment structure including a second support arm configured to extend over a second flange of the grid beam and a second leg extending down from the second support arm, and wherein the panel attachment structure is also removably coupled to the second grid attachment structure. For example, bracket  700  includes a second grid attachment structure  706  configured to attach to the opposite side of the grid beam. The post  756  of panel attachment structure  704  is positioned between the first grid attachment structure  702  and the second grid attachment structure  706  and is secured by fasteners  758  that extend through both grid attachment structures. As shown in  FIG.  8   , second grid attachment structure  706  is positioned on the opposing side of first grid beam  760 . Accordingly, the attachment wall of second grid attachment structure  706  is secured to an opposite side of the web of first grid beam  760  and the support arm of second grid attachment structure  706  extends over the second flange of the first grid beam  760 . 
     In certain embodiments of the bracket as otherwise described herein, the support arm has a width of at least ½ inch, e.g., at least 1 inch. Further, in some embodiments, the support arm has a width of no more than 8 inches, e.g., no more than 6 inches. For example, in some embodiments, the support arm has a width in a range from ½ inch to 8 inches, e.g., from 1 inch to 6 inches. 
     In certain embodiments of the bracket as otherwise described herein, the support arm has a depth of at least ⅛ inch, e.g., at least 3/16 inch. Further, in some embodiments, the support arm has a depth of no more than 1 inch, e.g., no more than ¾ inch. For example, in some embodiments, the support arm has a depth in a range from ⅛ inch to 1 inch, e.g., from 3/16 inch to ¾ inch. Further, in some embodiments of the ceiling system of the disclosure, the depth of the support arm is substantially the same as the outward lateral extension of the first flange of the first grid beam. For example, in some embodiments, the depth of the support arm is in a range of 1 to 1.5 times the lateral extension of the first flange of the first grid beam. For example, as shown in  FIG.  3   , the depth  112  of support arm  110  is slightly greater than the lateral extension of first flange  162 , such that the outer edge  118  of support arm  110  extends slightly past the edge of first flange  162 . 
     In certain embodiments of the bracket as otherwise described herein, the attachment wall height is at least ½ inch, e.g., at least ¾ inch. Further, in some embodiments, the attachment wall height is no more than 3 inches, e.g., no more than 2.5 inches. For example, in some embodiments, the height of the attachment wall is in a range from ½ inch to 3 inches, e.g., from ¾ inch to 2.5 inches. Further, in some embodiments of the ceiling system of the disclosure, the height of the attachment wall is substantially the same as the height of the web of the first grid beam. For example, in some embodiments, the height of the attachment wall is in a range of 0.5 to 1.0 times the height of the web of the first grid beam. For example, as shown in  FIG.  3   , the height  122  of attachment wall  120  is slightly less than the height of web  166  of first grid beam  160  such that attachment wall  120  can fit between first flange  162  and bulb  168 . 
     In certain embodiments of the bracket as otherwise described herein, the foot has a width of at least ½ inch, e.g., at least ¾ inch, e.g., at least 1 inch. Further, in some embodiments, the foot has a width of no more than 6 inches, e.g., no more than 5 inches, e.g., no more than 4 inches. For example, in some embodiments the foot has a width in a range from ½ inch to 6 inches, e.g., from ¾ inch to 5 inches, e.g., from 1 inch to 4 inches. Further, in some embodiments of the ceiling system of the disclosure, the width of the foot of the first bracket is substantially the same as the thickness of the first ceiling panel. For example, in some embodiments, the width of the foot is in a range of 0.5 to 1.0 times the thickness of the first ceiling panel. For example, as shown in  FIG.  4   , the foot  150  of bracket  100  extends substantially across the thickness of ceiling panel  170 . Configuring the foot with a width that is no more than the thickness of the ceiling panel can help to obscure the foot from view by a person below the ceiling panel. On the other hand, configuring the foot with a width that is close to the thickness of the ceiling panel provides added surface area for securing the ceiling panel to the foot. 
     In certain embodiments of the bracket as otherwise described herein, the foot has a length of at least 1 inch, e.g., at least 1.5 inches. Further, in some embodiments, the foot has a length of no more than 8 inches, e.g., no more than 6 inches. For example, in some embodiments, the foot has a length in a range from 1 inch to 8 inches, e.g., from 1.5 inches to 6 inches. 
     In certain embodiments of the bracket as otherwise described herein, the support arm has a thickness of at least 10 thousandths of an inch, e.g., at least 20 thousandths of an inch. Further, in some embodiments, the support arm has a thickness of no more than ¼ inch, e.g., no more than ⅛ inch. For example, in some embodiments, the support arm has a thickness in a range from 10 thousandths of an inch to ¼ inch, e.g., from 20 thousandths of an inch to ⅛ inch. Further, in some embodiments, the bracket has a substantially uniform thickness. For example, in some embodiments, the bracket is formed from a plate or sheet with a single thickness. In other embodiments, different portions of the bracket have different material thickness. For example, in some embodiments, one or more of the attachment wall, support arm, leg, or foot has a greater or smaller thickness than the others. 
     Likewise, in some embodiments, where the bracket includes a panel attachment structure and a grid attachment structure, such as the embodiments shown in  FIGS.  7  and  8   , the material thickness of the panel attachment structure and the grid attachment structure are the same. In other embodiments, the material thickness of the panel attachment structure and the grid attachment structure are different. Further still, in some embodiments, the various portions of the grid attachment structure have different material thickness. For example, in some embodiments, at least one of the attachment wall, support arm, or leg has a different material thickness than the others. Likewise, in some embodiments, the various portions of the panel attachment structure have different material thickness. For instance, in some embodiments, the material thickness of the foot is thicker or thinner than the material thickness of the post. 
       FIGS.  6  and  9    show larger portions of ceiling systems according to the disclosure.  FIG.  6    shows a ceiling system  680  that uses brackets  600  with the same configuration as bracket  100 , and  FIG.  9    shows a ceiling system  980  that uses brackets  900  having the same configuration as bracket  700 . While all of the brackets in ceiling system  680  of  FIG.  6    have the same configuration, and all of the brackets in ceiling system  980  of  FIG.  9    have the same configuration, in other embodiments, the ceiling system may use a variety of different brackets with different configurations. For example, in some embodiments, the ceiling system includes a number of brackets with a fixed angle of the foot and a number of brackets with a selectable angle of the foot. 
     In certain embodiments of the ceiling system as otherwise described herein, the ceiling system includes a second bracket according to the disclosure coupled to the first grid beam and a second ceiling panel, where the foot of the second bracket is attached to the second ceiling panel. For example, ceiling system  680  shown in  FIG.  6    includes a first grid beam  660 A with a first bracket  600 A and a second bracket  600 B coupled thereto. Ceiling system  680  also includes a first ceiling panel  670 A coupled to the foot of first bracket  600 A and a second ceiling panel  670 B coupled to the foot of second bracket  600 B. The brackets  600 A,  600 B are both oriented to hold the respective ceiling panels  670 A,  670 B at an angle to the ceiling grid. 
     Likewise ceiling system  980  shown in  FIG.  9    includes a first grid beam  960  and a first ceiling panel  970 A coupled to first grid beam  960  using a first bracket  900 A. Ceiling system  980  also includes a second ceiling panel  970 B coupled to first grid beam  960  using a second bracket  900 B. The first bracket  900 A is arranged so that first ceiling panel  970 A is at an angle to the ceiling grid, and the second bracket  900 B is arranged so that the second ceiling panel  970 B is also at an angle to the ceiling grid. 
     In certain embodiments of the ceiling system as otherwise described herein, the foot of the second bracket holds the second ceiling panel at the same angle as the first ceiling panel. For example, in ceiling system  680  and in ceiling system  980  all of the ceiling panels are oriented at the same angle. In other embodiments, the ceiling panels are arranged at different angles. For example, in some embodiments, the brackets in the ceiling system are constructed to hold the ceiling panels at different angles. Further, in some embodiments, the brackets are adjustable, and may be set so that the ceiling panels have a variety of different angles. 
     In certain embodiments of the ceiling system as otherwise described herein, the ceiling system includes a second grid beam and another bracket according to the disclosure coupled to the second grid beam, wherein the foot of the other bracket is attached to the first ceiling panel. For example, ceiling system  680 , as shown in  FIG.  6   , includes a second grid beam  660 B that supports the ceiling panels. Thus, near the far end of first ceiling panel  670 A, another bracket  600 C is used to couple first ceiling panel  670 A to the second grid beam  660 B. 
     In some embodiments, the other bracket has the same configuration as the first bracket. For example, in ceiling system  680  the other bracket  600 C is attached to the near side of second grid beam  660 B and has the same configuration as bracket  600 A. In other embodiments, the brackets may have different configurations. For example, in some embodiments, the other bracket has a mirror configuration to the first bracket. For example, in some embodiments, brackets at opposing ends of the ceiling panel are configured as a mirror-image to one another so that the attachment is symmetrical over the length of the ceiling panel. For example, in some embodiments the two brackets near opposing ends of the ceiling panel both extend toward the respective ends of first ceiling panel and hold first ceiling panel at the same angle. In other embodiments, brackets used to attach a ceiling panel to different grid beams have the same configuration, and are positioned on the same side of the respective grid beams. 
     On the other hand, in other embodiments both brackets have the same configuration, and are positioned on the same side of the first and second grid beams so that they may hold the first ceiling panel at the same orientation. Still, in other embodiments, the brackets have a symmetrical configuration, and may hold a ceiling panel angled at either direction regardless of which side of the grid beam the bracket is attached to. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the processes and devices described here without departing from the scope of the disclosure. Thus, it is intended that the present disclosure cover such modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
