BACKGROUND
Gaming machines have used various types of displays to present a game of chance to a player. Traditionally, gaming machines have used a plurality of mechanical reels having various symbols provided on the reels. However, gaming machines have increased in their complexity and player features to maintain player interest. As a result, gaming machines have been developed that use video displays such as, but not limited to, Cathode Ray Tube (CRT) monitors to present games of chance. While useful, CRT monitors use a large amount of space within the gaming machine cabinet.
In addition to CRT monitors, flat panel displays, such as LCD or plasma displays, have also been used in gaming machines. While these flat panel displays occupy less space within the gaming machine, the mounting locations of these displays within a gaming cabinet inhibit access or block portions of the gaming cabinet. Accordingly, the flat panel display needs to be removed from the gaming cabinet to access portions of the gaming cabinet, thereby increasing the complexity and costs of maintaining a gaming machine. What is needed are mounting assemblies that allow a flat panel display to be viewable by a player to provide easier access to the interior of the gaming machine cabinet.

One of ordinary skill in the art will appreciate that not all gaming machines have all these components and that each gaming machine may have other components in addition to, or in lieu of, those components mentioned here. Furthermore, while these components are viewed and described separately, various components may be integrated into a single unit in some embodiments.
FIG. 2 illustrates one embodiment of the gaming machine 10 in which the main door 20 has been opened to expose the interior of the gaming machine. As shown in FIG. 2, the main display 22 is fixed in an operating position. In the operating position, the main display 22 is located within the gaming machine 10 such that the display is positioned over a portion of the interior of the main cabinet 18 and is viewable through the display opening 46 of the main cabinet door 20 when the main cabinet door is in a closed position. Additionally, the guide members 48 act as a stop to prevent the main display 22 from hitting the main door opening 46. As shown in FIG. 2, the main cabinet door 20, optionally, includes one or more guide members 48 that align the main door opening 46 with the main display 22.
As shown in FIG. 2, the main display 22 is movably coupled to the hinges 50 of gaming machine 10 via a display mount 40. According to one embodiment, the display mount 40 includes one or more hinges 80 coupled to a frame. The frame is shaped and sized to correspond to the shape and size of the main display 22. In an alternate embodiment, the hinges 80 are directly coupled to the main display 22.
As shown in FIGS. 2-4, the display mount 40 includes two hinges 80, but other embodiments of the display mount 40 may include one or more hinges. For example, a display mount (not shown) having a single hinge may used for a main display 22 that is relatively small and/or light weight. Alternatively, a display mount (not shown) may have three or more hinges for a main display that is large and/or heavy.
In another embodiment, the display mount 40 includes a latch structure 42 that is located opposite the hinges 80 as shown in FIG. 4. According to one embodiment, the latch structure 42 is coupled to or integral with the frame of the display mount 40. Alternately, the latch structure 42 is directly coupled to the display 22. The latch structure 42 is configured to engage a bracket 44 that is positioned on the main cabinet 18. As a result, the main display 22 is secured in the operating position by a latch structure 42 positioned on the frame of the main display 22. The latch structure 42 prevents the main display 22 from inadvertently moving when the main cabinet door 20 is opened.
Referring back to FIG. 3, the display mount 40 is shown in a service position. In the service position, the main display 22 is moved away from the interior of the main cabinet 18 thereby allowing for better access to components within the main cabinet. While FIG. 3 illustrates the main display 22 moved slightly away from the interior of the main cabinet 18, the main display may be moved to any position spaced away from the interior of the main cabinet. When the main display 22 is moved into the service position, components (not shown) in the interior 70 of the main cabinet 18 are more accessible by casino technicians.
According to one embodiment, when the display mount in is the service position, the main display 22 engages the main door 20 of the cabinet 18 via the guide members 48. More specifically, the edges of the display mount 40 engage guide members 64 on the main door via friction fit. The guide members 64 are long enough to prevent the display screen 22 from contacting the main door 20. In this configuration, the display 22 is movable into a position that provides better access to the interior of the main cabinet 18. Additionally, in this configuration, when the main door is moved from the open position to the closed position, the main display 22 moves with the main door 20. When the main door 20 is completely closed, the display mount latch 60 engages the slot 62 of the main cabinet 18. Accordingly, when the main door 20 is subsequently opened, the display screen 22 is securely mounted in the operating position.
FIGS. 4-6 illustrate one embodiment of a display screen 22 having a mounting assembly 42 including a hinge 80 and a latch structure 42. These structures 80 and 42 are secured to the frame of a display assembly via screws, rivets, or other fasteners known or developed in the art. As shown in FIG. 4, the structures 80 and 42 are positioned on opposite ends of the display screen 22.
