[0030] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and for providing a comer adjustment assembly for a display unit. The various concepts introduced above and discussed in greater detail below may be implemented in any of a number of ways, as the described concepts are not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.Display Assembly

[0031] Referring to FIGS. 1-2, a display assembly 10 for a display system includes multiple truss structures 14 (e.g., structural assemblies, bars, beams, cantilevered beams, support structures, etc.) anchored to a ground surface 12. The truss structures 14 may be anchored via ground anchors 16 that couple the truss structures 14 with the ground surface 12. The truss structures 14 extend vertically from the ground surface 12 and support multiple display units 102 (e.g., display screens, arrays of light emitting diodes, lighting assemblies, projectors, display interfaces, touch screen displays, etc.). The display units 102 are coupled with the truss structures 14 and oriented in a variety of directions to provide a wrap-around display assembly. The display assembly 10 may provide the display units 102 for flight simulation training or other seamless wrap-around visual display systems.

[0032] The display assembly 10 also includes corner assemblies 100 (e.g., adjustment assemblies, structural assemblies, adjustable corner units, rotatable corner units, repositionable corner assemblies, etc.) that are coupled on top of the truss structures 14 at a first connection point of the corner assemblies 100. The corner assemblies 100 are coupled with upper trussstructures 18 at a second connection point opposite the first connection point. The upper truss structures 18 are coupled with corresponding display units 102 that are angled inwards to provide display of imagery in an upper location of the display assembly 10. The display units 102 may form a dome to provide surround visual imagery. The comer assemblies 100 are configured to both structurally support the display units 102 and orient the display units 102 in multiple directions. When the display units 102 require service or adjustment to orient the display units 102 into proper alignment, the corner assemblies 100 may be adjusted to allow access to portions of the display units 102 for maintenance or to properly align the display units 102 relative to each other. The truss structures 14, corner assemblies 100, and upper truss structures 18 may form columns 30 that are disposed in a pattern on the ground surface 12 (e.g., a polygonal arrangement, such as an octagonal arrangement). In order to orient the display units 102 that are coupled with the upper truss structures 18 properly, the comer assemblies 100 may be configured to re-orient the display units 102 and upper truss structures 18 in multiple directions (e.g., about a first axis and a second axis).

[0033] Referring particularly to FIGS. 2-4, the comer assemblies 100 are configured to reorient the upper truss structures 18 and the display units 102 about a horizontal axis, shown as first axis 128. The display units 102 and the truss structures 18 may be driven to rotate about the first axis 128 by operation of the corner assemblies 100. In some embodiments, rotation of the upper truss structures 18 and the display unit 102 about the first axis 128 facilitates rotating the display unit 102 into a position such that a rear of the display unit 102 can be accessed by technicians for maintenance operations. The display unit 102 and the upper truss structures 18 may be driven to rotate about the first axis 128 in either of a first direction 22 (e.g., such that the display unit 102 is oriented downwards, towards the ground surface 12) and a second direction 24 (e.g., such that the display unit 102 is oriented upwards, away from the ground surface 12). In some embodiments, the display unit 102 and the upper truss structure 18 can be driven an angular range 20 (e.g., a span) up to 90 degrees. For example, from a neutral or vertical position where the upper truss structure 18 aligned with the truss structure 14 of the column 30, the display unit 102 and the upper truss structure 18 may be configured to rotate 60 degrees in the first direction 22 and 30 degrees in the second direction 24.

[0034] Referring to FIGS. 4 and 5, the upper truss structure and the display unit 102 may be further configured to rotate about a vertical axis, shown as second axis 134. The second axis 134 is perpendicular to the first axis 128, according to some embodiments. In some embodiments, the display unit 102 and the upper truss structure 18 are configured to be rotated 90 degrees in either direction about the second axis 134. Rotating the display unit 102 and the upper trust structure 18 about the second axis 134 may be performed to improve access to a rear of the display unit 102 for maintenance (e.g., to change light emitting diodes (“LEDs”)) or to properly align the display unit 102 with neighboring display units 102.Corner Adjustment Assembly[00351 Referring to FIG. 6, the comer assembly 100 is shown in greater detail, according to some embodiments. The corner assembly 100 is configured to facilitate re-orientation (e.g., rotation) of the display unit 102 about the first axis 128 and the second axis 134. The comer assembly 100 includes a first coupling plate 104 (e.g., a first plate, a first coupler, a first structural member, etc.) and a second coupling plate 106 (e.g., a second plate, a second coupler, a second structural member, etc.). The corner assembly 100 also includes a hinge 108 (e.g., a hinge assembly, a hinge member, a hinge apparatus, etc.), a bearing 142 (e.g., a ball bearing, a roller bearing, a linear bearing, etc.), and a fastener 138. The first coupling plate 104 and the second coupling plate 106 are rotatably coupled with each other about the hinge 108. The hinge 108 defines the first axis 128 at a pin 130 that pivotally couples a first hinge member 110 with a second hinge member 112 of the hinge 108. The first hinge member 110 is fixed (e.g., welded, fastened, anchored, etc.) with the first coupling plate 104, according to some embodiments. In some embodiments, the second hinge member 112 is fixed with the second coupling plate 106 (e.g., welded, fastened, anchored, etc ).[0036[ The first coupling plate 104 and the second coupling plate 106 may have generally triangular shapes corresponding to shapes of the truss structure 14 and the upper truss structure 18. In some embodiments, the first coupling plate 104 and the second coupling plate 106 include openings, apertures, structure, etc., to facilitate coupling the first coupling plate 104 with the truss structure 14 and the second coupling plate 106 with the upper truss structure 18.|0037] The hinge 108 includes the pin 130 that defines a pivot point of the hinge 108 (e.g., the first axis 128), according to some embodiments. The first hinge member 110 may include a pair of plates that are spaced apart from each other and are received within a corresponding pair of plates of the second hinge member 112. The pin 130 extends through both the first hinge member 110 and the second hinge member 112 and is coupled with the first hinge member 110 and the second hinge member 112 via bearings 132 to facilitate rotation of the second hinge member 112 relative to the first hinge member 110. The first hinge member 110 may be positioned at a front side 150 of the first coupling plate 104.[0038| Referring still to FIG. 6, the corner assembly 100 includes a drive apparatus 116 (e.g., a drive member, a linear drive member, an extendable member, a screwjack, etc.). The drive apparatus 116 may be configured to receive a manual torque input and use the manual torque input to drive rotation of the second hinge member 112 (and therefore the second coupling plate 106 and the display unit 102) about the first axis 128. As shown in FIG. 6, the drive apparatus 116 is provided as a screwjack including a gear box 124 (e.g., a transfer case), a drive shaft 120 (e.g., an input shaft, a rotatable shaft, an input screw, etc.), a drive wheel 122 (e.g., an input device, a user interaction device, a lever, a handle, etc.), and a screw 118 (e.g., an output shaft, a linearly extending or retracting shaft, etc.). The screw 118 is coupled with a rear of the second hinge member 112, according to some embodiments. In some embodiments, the screw 118 includes an end 148 that is received within a pair of flanges 146 and is pinned via pin 144. The pair of flanges 146 extend from a plate 126 that is coupled (e.g., fastened) with the second hinge member 112, according to some embodiments. The drive apparatus 116 may be coupled (e.g., fastened) with the first coupling plate 104 at a back side 152 of the first coupling plate 104. In some embodiments, the drive apparatus 116 is an electric motor that can be electronically operated by a corresponding controller or processor. In some embodiments, the drive apparatus 116 is provided as a cable and winch system that can be adjusted to rotate the second hinge member 112 and the second coupling plate 106 about the first axis 128. The cable and winch system may include a cable that is coupled with the second coupling plate 106 and a handle and spool such that the cable can be wound onto the spool and let off the spool to adjust orientation of the second coupling plate 106 and the second hinge member 112 about the first axis 130. The handle and spool of the cable and winch system may be provided lower onthe truss structure 14 such that the handle can be operated by a user standing on the ground surface 12.

[0039] The drive shaft 120 is driven to rotate by the drive wheel 122 (e.g., by manual operation by the user), according to some embodiments. The drive shaft 120 is configured to rotate about a corresponding axis that extends centrally through the drive shaft 120, and drive translation of the screw 118 along an axis different than the axis about which the drive shaft 120 is rotated. The gear box 124 may include a worm drive or other gearing arrangement to convert rotation of the drive shaft 120 into translational motion of the screw 118. Translation of the screw 118 causes the second hinge member 112 to rotate about the first axis 128 to rotate the display unit 102. In this regards, the display unit 102 (e.g., the second hinge member 112 and the second coupling plate 106) can be driven to rotate about the first axis 128 by operating (e.g., rotating) the drive wheel 122. The drive apparatus 116 may have a crank ratio sufficiently high such that adjustments to the orientation of the display unit 102 about the first axis 128 may be accomplished manually (by hand). For example, the crank ratio from input to output may be about 6: 1.

[0040] Referring still to FIG. 6, the second coupling plate 106 is rotatably coupled with the second hinge member 112 through the fastener 138 and the bearing 142, according to some embodiments. The fastener 138 and the bearing 142 are co-axial with each other and define the second axis 134, according to some embodiments. The second coupling plate 106 is configured to rotate about the second axis 134 independently of rotation of the second hinge member 112 about the first axis 130 such that the second coupling plate 106 and the upper truss structure 18 and display unit 102 can be re-oriented about the second axis 134, according to some embodiments. For example, the second coupling plate 106 may be rotated about the second axis 134 without requiring corresponding rotation of the second hinge member 112 about the first axis 130. Likewise, the hinge member 112 may be driven to rotate about the first axis 130 without requiring rotation of the second coupling plate 106 about the second axis 134. The fastener 138 may be coupled with the second coupling plate 106 via a nut 140 (e.g., a cage nut).

[0041] Referring particularly to FIGS. 7 and 8, the bearing 142 is shown in greater detail, according to some embodiments. The bearing 142 may be a roller bearing, a needle bearing,etc., and is disposed within the second coupling plate 106. The bearing 142 can be positioned centrally on the second coupling plate 106. The bearing 142 includes a central opening through which the fastener 138 extends. The fastener 138 may extend through a corresponding opening of the second hinge member 112 to couple the second hinge member 112 with the second coupling plate 106.

[0042] Referring to FIGS. 6-8, the second coupling plate 106 includes a handle 136 (e.g., an arm, a crank arm, a lever, etc.). The handle 136 is retractable between a stowed position 137a and a deployed position 137b, according to some embodiments. In some embodiments, the handle 136 can be rotated between the stowed position 137a and the deployed position 137b and locked in the stowed position 137a or the deployed position 137b. When the handle 136 is in the stowed position 137a, the handle 136 may align with an edge or side of the second coupling plate 106. When the handle 136 is in the deployed position 137b, the handle 136 protrudes from the second coupling plate 106. The handle 136 may be rotatably or pivotally coupled with the second coupling plate 106 via a pin 162. The second coupling plate 106 also includes a pair of removable pins 160 that can be removed from corresponding openings in the second coupling plate 106 and re-inserted to lock the handle 136 in either the stowed position 137a or the deployed position 137b.

[0043] Referring to FIGS. 7-8, the second hinge member 112 also includes a locking pin 154. The locking pin 154 extends from a side of the second hinge member 112 opposite a side on which the second hinge member 112 couples with the second coupling plate 106. The locking pin 154 may be spring loaded and is positioned at a first radius relative to the second axis 134. In some embodiments, the locking pin 154 is configured to be received within one of multiple openings 156a- 156c in the second coupling plate 106. As shown in FIGS. 7-8, the openings 156a- 156c include a first opening 156a, a second opening 156b, and a third opening 156c. The first opening 156a, the second opening 156b, and the third opening 156c are positioned outwards from the second axis 134 at the first radius. The first opening 156a, the second opening 156b, and the third opening 156c define different positions for the second coupling plate 106 and the display unit 102 about the second axis 134. In some embodiments, the second opening 156b defines a normal or rest position in which an axis normal to a surface of the display unit 102 is perpendicular with a plane defined between the first axis 128 and thesecond axis 134 (e.g., the orientation as shown in FIGS. 3 and 4). The first opening 156a defines a right position in which the display unit 102 is oriented to face a right direction. The third opening 156c defines a left position in which the display unit 102 is oriented to face a left direction opposite the right direction. In this way, the display unit 102 and the second coupling plate 106 can be re-orientable about the second axis 134 in either direction, and can also be configured to be locked in multiple orientations.|0044] In order to transition the display unit 102 and the second coupling plate 106 out of a current position or orientation about the second axis 134 and transition the coupling plate 106 into a different position or orientation about the second axis 134, the locking pin 154 may first be removed. The locking pin 154 can be pulled such that the locking pin 154 does not extend through a corresponding one of the openings 156a- 156c (e.g., the second opening 156b). The second coupling plate 106 and the display unit 102 may be rotated in either direction about the second axis 134 until the locking pin 154 aligns with either the first opening 156a or the third opening 156c. The locking pin 154 may then be re-inserted through the second hinge member 112 into the corresponding first opening 156a or third opening 156c to lock the display unit 102 and the second coupling plate 106 in either the first or third position corresponding to the first opening 156a and the third opening 156c. In some embodiments, after the locking pin 154 is removed, the second coupling plate 106 and the display unit 102 may be rotated about the second axis 134 by transitioning the handle 136 into the deployed position and using the handle 136 to rotate the second coupling plate 106 and the display unit 102. In some embodiments, the locking pin 154 is spring loaded such that the locking pin 154 is automatically driven into engagement with the second coupling plate 106 when the locking pin 154 is aligned with one of the openings 156a-156c. The third opening 156c and the first opening 156a may be disposed 90 degrees from the second opening 156b in opposite directions about the second axis 134 at the first radius to provide three predetermined angular positions of the display unit 102 and the second coupling plate 106.

[0045] In some embodiments, the predetermined angular positions may correspond to alignment of the locking pin 154 with the openings 156a- 156c. A first angular position (e.g., a normal position, a default position, etc.) is provided when the locking pin 154 is received within the second opening 156b, according to some embodiments. A second angular position(e.g., 90 degrees to the right) is provided when the locking pin 154 is received within the first opening 156a, according to some embodiments. A third angular position (e.g., 90 degrees to the left) is provided when the locking pin 154 is received within the third opening 156c, according to some embodiments. In some embodiments, more than three openings 156a-156c are provided such that the second coupling plate 106 and the display unit 102 can be locked in more than three predetermined angular positions. In some embodiments, the three openings 156a- 156c are spaced other than 90 degrees (e.g., the first opening 156a and the third opening 156c may be disposed 30 degrees or 60 degrees relative to the second opening 156b).[0046| Referring to FIGS. 7 and 8, the second hinge member 112 also includes a safety pin 164. The safety pin 164 is spring loaded such that the safety pin 164 maintains engagement with the second coupling plate 106 and automatically locks to prevent over-rotation of the second coupling plate 106, according to some embodiments. In some embodiments, the safety pin 164 is positioned at a second radius relative to the second axis 134 that is different than the first radius at which the locking pin 154 is positioned. The second coupling plate 106 includes a first groove 158a and a second groove 158b formed in a face of the second coupling plate 106 that faces the second hinge member 112. The first groove 158a and the second groove 158b are positioned outwards from the second axis 134 at the second radius. The first groove 158a and the second groove 158b have an arcuate shape corresponding to a circumference having the second radius. The first groove 158a and the second groove 158b have a variable depth and a descending surface that terminates at a lowest point at an end of the first groove 158a and the second groove 158b. The first groove 158a and the second groove 158b may be configured to limit further rotation of the second coupling plate 106 and the display unit 102 past the positions at which the locking pin 154 is aligned with the first opening 156a or the third opening 156c.

[0047] For example, when transitioning the display unit 102 and the second coupling plate 106 from a first position in which the locking pin 154 is received within the second opening 156b to a second or third position in which the locking pin 154 is received within the first opening 156a or the third opening 156c, the safety pin 164 may limit further rotation past the second or third position. For example, the safety pin 164 may be spring loaded such that the safety pin 164 maintains engagement with the second groove 158b (e g., “walks along the second groove158b) as the second coupling plate 106 is rotated in order to align the locking pin 154 with the first opening 156a. When the safety pin 164 has reached an end of the second groove 158b after walking along a surface of the second groove 158b, the safety pin 164 may abut a vertical surface of the second groove 158b to limit further rotation beyond the end of the second groove 158b. The safety pin 164 can therefore limit over-rotation of the second coupling plate 106 and the display unit 102 beyond 90 degrees in either direction. The safety pin 164 does not need to be pulled out of engagement with the first groove 158a or the second groove 158b to rotate the second coupling plate 106 back from the end of the first groove 158a or the second groove 158b due to the sloped shape of the first groove 158a and the second groove 158b. In this way, the safety pin 164, the first groove 158a, and the second groove 158b provide limits for overrotation of the second coupling plate 106 and the display unit 102 while allowing back-rotation of the second coupling plate 106 and the display unit 102.

[0048] Referring to FIGS. 6 and 7, the first hinge member 110 includes an alignment pin 114 (e.g., a set screw, a screw, etc.) that is threadingly coupled with a side of the first hinge member 110. The alignment pin 114 is coupled with a side of the first hinge member 110 and can be adjusted (e.g., rotated) to translate towards or away from a corresponding surface 166 of the second hinge member 112. The alignment pin 114 may be rotated into engagement with the corresponding surface 166 of the second hinge member 112 in order to mark a current position or orientation of the second hinge member 112 relative to the first hinge member 110. The alignment pin 114 may advantageously provide a marker of a desired angular position about the first axis 128 for the second hinge member 112 and the coupling plate 106. When the drive apparatus 116 is driven to rotate the second hinge member 112 and the second coupling plate 106 in a rearwards direction about the first axis 128 (e.g., such that the corresponding surface 166 is driven out of engagement with the alignment pin 114), the alignment pin 114 may mark a position about the first axis 128 such that, when maintenance is completed, the drive apparatus 116 can be operated to return the second hinge member 112 and the second coupling plate 106 to a previous angular position about the first axis 128. Advantageously, the alignment pin 114 can be used so that the second coupling plate 106 and the second hinge member 112 can be returned to a previous angular position about the first axis 128.|0049] Referring again to FIGS. 1-8, the display units 220 may each have a weight of between about 150 pounds to about 250 pounds, e.g., over about 200 pounds (e.g., about 220 pounds). In some embodiments, the upper truss structure 18 may have a weight of between about 15 pounds to about 25 pounds, e.g., about 20 pounds. In some embodiments, the comer adjustment assembly 100 has a weight of about 75 pounds to about 100 pounds, e.g., 90 pounds. The weights above are provided as representative examples to which the claims are not limited. The upper truss structure 18 and the truss structures 14 may be manufactured from aluminum or other metals or combinations of metals. Advantageously, the comer assembly 100 provide robust adjustment assemblies that can support the display units 102 and the upper truss structures 18 and facilitate precise re-orientation of the display units 102 for alignment and / or maintenance operations.Configuration of Example Embodiments|0050] While this specification contains specific implementation details, these should not be construed as limitations on the scope of what may be claimed but rather as descriptions of features specific to particular implementations.
