DETAILED DESCRIPTION
(27) As depicted in FIGS. 1-4, a cabinet system 20, according to an example of the present subject matter, can comprise a protective shroud 22 having a support frame 24 and at least one mounting assembly 26. The protective shroud 22 can include a frame 28 and at least one window frame 30 for receiving a transparent window 32. The window frame 30 can be affixed to a rectangular frame 28 to define an internal space for receiving at least one electronic display. As depicted in FIG. 3, in at least one example, a transparent window can be mounted to the rectangular frame 28 to allow viewing of the electronic display while preventing contaminants from entering the inner space protected by the protective shroud 22. As depicted in FIG. 5, in at least one example, a cover 106 can be affixed to the wind frame 30 to prevent viewing into the protected space. In an example, the rectangular frame 28 can comprise a generally rectilinear-shaped frame, as electronic displays typically have a rectangular shape. For this reason, the rectangular frame 28 will be referred to herein as a rectangular frame 28. However, it is contemplated that other shaped frames can be used.
(28) The cabinet system 20 can enclose an electronic display that can provide for the display of visual information, e.g., textual information, photos, or video information. The electronic display can include an array of a plurality of light-emitting elements that can be configured and controlled to display the visual information, as is known in the art. The electronic display can comprise, but is not limited to light-emitting diodes (LEDs) displays, organic light-emitting diodes (OLEDs) displays, organic light-emitting transistors (OLETs) displays, surface-conduction electron-emitter display devices (SEDs), field-emission display devices (FEDs), laser TV quantum dot liquid crystal display devices, quantum dot display devices (QD-LED), ferro-liquid display devices (FLDs), liquid crystal display devices (LCDs), and thick-film dielectric electroluminescent devices (TDELs). Examples of electronic displays that can be used with the cabinet system 20 of the present disclosure can include, but are not limited to, electronic display modules sold under the AF-6xxx Series trademark by DAKTRONICS, INC., Brookings, S. Dak., USA, the disclosures of which are incorporated herein by reference. In an example, the rectangular frame 28 can include at least one display mount 29 for receiving and positioning the display such that the display is visible through the window frame 30. In certain examples, the frame 28 can include mirrored display mounts 29 positioned in parallel for positioning displays in opposite directions for viewing of the displays from at least two opposing directions.
(29) The rectangular frame 28 can include a lip 32 for securing the window frame 30 to the rectangular frame 28. In an example, the window frame 30 can be secured to a corresponding lip 32 using one or more fasteners 33 to secure the window frame 30 to the lip 32. The fasteners 33 can comprise, for example, screws, brads, staples, welds, pins, bolts, and the like. The window frame 30 can also be secured to the rectangular frame 28 with adhesive in place of, or in addition to, fasteners. In certain examples, the interface between the lip 32 and the window frame 30 can be sealed, such as with a gasket or other sealing device, to prevent moisture or contaminants from penetrating between the rectangular frame 28 and the window frame 30. As depicted in FIG. 1, in certain examples, the protective shroud 22 can include at least two window frames 30 positioned on opposing sides of the rectangular frame 28.
(30) As depicted in FIG. 13A, in an example, the window frames 28, 30 can include a releasable locking element 80 for releasably securing each window frame 28, 30 to the protective shroud 22. The locking element 80 can include a recessed mounting element 82 having a bore hole for receiving a locking fastener 84. In this configuration, the lip 32 of the protective shroud 22 can include a corresponding bore hole for receiving the locking fastener 84 to secure the window frame 28, 30 to the protective shroud 22. In an example, the window frame 28, 30 can include an access port 86 through which the locking fastener 84 is inserted to access the recessed mounting element 82. The recessed configuration of the mounting element 82 conceals the locking fastener 84 of the mounting element 82. The mounting element 82 also reduces the likelihood that moisture and contaminates will penetrate the between the window frame 28, 30 and the protective shroud 22 through the access port 86. In certain examples, the access port 86 can be sized to further shield the recessed mounting element 84 from additional exposure from moisture and environmental conditions. In an example, the protective shroud 22 can include a secondary locking feature 88 that further engages the locking fastener 84 to prevent slippage of the locking fastener 84 due to temperature changes and other environmental conditions creating gaps between the window frame 28, 30 and the protective shroud 22. As depicted in FIG. 13B, in an example, the releasable locking element 80 can further comprise a bias spring 89 that engages the fastener 84 against the secondary locking feature 88 to further secure the fastener 84.
(31) The support frame 24 can include a plurality of rigid struts 34a, 34b (collectively referred to herein as rigid struts 34 or rigid strut 34). In an example, the rigid struts 34a, 34b can be arranged end-to-end to define the shape of the rectangular frame 28, e.g., by defining a rectangular shape positioned around the example rectangular frame 28 of the protective shroud 22 as shown in FIG. 1. As depicted in FIG. 2, in at least one example, the rigid struts 34a, 34b can have shortened struts that do not extend entirely around the protective shroud 22, but generally define a rectangular shape. The rigid struts 34 can comprise a tubular structure for receiving at least one fastener 36 extending through the center of the rigid strut 34 into the rectangular frame 28 of the protective shroud 22 to secure the rigid strut 34 to the rectangular frame 28.

The first plurality of rigid struts 34a can be positioned on a first side 49a of the cabinet system 20 and the second plurality of rigid struts 34b can be positioned on an opposing second side 49b of the cabinet system 20. The first plurality of rigid struts 34a and the second plurality of rigid struts 34b can be arranged around the rectangular frame 28 in parallel to define a raceway 51 between the rigid struts 34a, 34b. The raceway 51 can receive and guide the cabling around an exterior of the protective shroud 22. As depicted in FIGS. 14-15, in an example, the mounting arm 46 can define a cable channel 47 through which cabling can be pass through and directly enter the raceway 51 without exposing the cabling and the raceway 51 to exterior conditions. The first plurality of rigid struts 34a can include at least one first track strut 40a comprising at least one first elongated track 42a. The second plurality of rigid struts 34b can include at least one second track strut 40b comprising at least one second elongated track 42b. In this configuration, each foot 44 can span between the sides 49a, 49b of the cabinet system 20 and can be configured to engage each rigid strut 34a, 34b, such as by receiving the at least one fastener 48 for engaging each track strut 40a, 40b to prevent torquing of the protective shroud 22 relative to the mounting arm 46.
(34) As depicted in FIGS. 3-4, in an example, the cabinet system 20 can include an outer shroud 50 sized to receive the protective shroud 22 and the support frame 24 or to the inner protective shroud 22. The outer shroud 50 can be configured to receive at least one fastener 51 to secure the outer shroud 50 to the external frame 24. The outer shroud 50 can comprise a shape that corresponds to the shape of the protective shroud 22 and the support frame 24. For example, in order to correspond to the example rectangular shroud 22 and the example rectangular frame 24, the outer shroud 50 can include a rectangular frame 52. The outer shroud 50 can also include at least one window frame 54 for mounting a window 56 to the rectangular frame 52. The outer shroud 50 can comprise at least two window frames 54 positioned to align with the windows 32 of the protective shroud 22. The outer shroud 50 can also comprise at least one slot 58 positioned to align with the elongated track 42 in the rigid struts 34 of the support frame 24. In this configuration, each fastener 48 of the foot 44 can extend through the slot 58 of the outer shroud 50 to secure the foot 44 to the track 42 of the support frame 24 so that the outer shroud 50 can be secured to the inner protective shroud 22. As depicted in FIG. 12, in an example, the outer shroud 50 can include removable top cover 53 that interlocks with the window frames 30 to facilitate easier access to the raceway 51. In at least one example, the outer shroud 50 can include a cable port through which cabling can be fed into the raceway 51. The cable port can be aligned to receive cabling from the cable channel 47. In certain example, the top cover 53 can comprise a lip portion 55 that interfaces with the window frame 54 to prevent moisture from penetrating the raceway 51 between the top cover 53 and the window frame 30.
(35) The mounting assembly 26 further can comprise a mounting plate 60 positionable between the protective shroud 22 and the outer shroud 50. The mounting plate 60 can be configured to receive each fastener 48 such that mounting plate 60 operates to slidably retain the foot 40 against the outer shroud 50.
(36) As depicted in FIGS. 14-15, in an example, the inner protective shroud 22 can further comprise at least one cabling port 62. In at least one example, each cabling port 62 can include an elastomer stopper 62 defining at least one cabling conduit 64 for receiving a cable. In certain examples, the elastomer stopper 62 can be sized to seal against the edges of the cabling port 62 to prevent moisture and contaminants from passing between the elastomer stopper 62 and the edges of the cabling port 62. The cabling conduit 64 can be sized to seal against cabling positioned within the cabling conduit 64 to prevent leakage of moisture or contaminants through the cabling conduit 64.
(37) As depicted in FIGS. 2 and 15-16, in at least one example, the protective shroud 22 can further comprise a cable box 90 that can be engaged to the cabling port 62. The cable box 90 includes a housing 92 and a secondary cable port 94 for receiving cabling from the raceway into the protected space. The housing 92 is angled inward into the protected space to angle the secondary cable port 94 relative to the exterior of the protective shroud 22. The angling of the secondary cable port 94 reduces stress on cabling entering the secondary cable port 94 by bending the cabling less than 90 degree to pass the cabling through the protective shroud 22. In an example, an elastomer stopper 96 can be positioned in the secondary cable port 94 to seal against the cabling.
(38) As depicted in FIGS. 1-4, in an example, the inner protective shroud 22 can further comprise at least one access opening 66. Each access opening 66 can be positioned on the underside of the inner shroud 22 to minimize the likelihood that moisture or contaminants from penetrating the protected space of the inner shroud 22. In an example, an access door (not shown) can be positioned within the access opening 66 to limit access the protected space. The access door can be configured to provide a seal against the access opening 66 preventing or minimizing penetration by moisture or contaminants through the access openings 66.
