Description:
BACKGROUND OF THE INVENTION 
     This invention relates to entertainment systems and more specifically to housing assemblies integrated into entertainment systems utilized on transportation vehicles. 
     Today&#39;s world involves numerous situations in which one is required to endure trips of varying distance and time for both pleasure and work reasons. To accomplish these travels a wide assortment of personal and commercial vehicles including automobiles, buses, ships, trains and aircraft are relied upon on a daily basis. For those individuals not operating the respective vehicle, the duration of the trip provides a captive situation which is often addressed by access to wireless broadcast information, such as television, or viewing pre-recorded information stored on the vehicle for playback during the trip. Such systems are often referred to as in-flight or mobile entertainment systems. With advances in electronics in recent years, with respect to size, cost and ruggedness, such in-flight entertainment systems are commonly found in numerous vehicles. 
     One drawback to the present day utilization of in-flight entertainment systems, is the maintenance associated with the display or monitor stowage and deployment. In order to provide maximum viewing access, the physical location of the display or monitor often subjects the device to excessive stress, both planar and rotational, when deployed. Additionally, the operating environment of such entertainment systems is often characterized by high vibration and deliberate misuse in attempting to deploy or retract the display. 
     Accordingly, a need exists for an in-flight entertainment system incorporating a display housing system that secures stowage and deployment, while deflecting predictable extreme applied force is highly desirable, and simultaneously incorporating features that accommodate quick replacement of the housed display unit. 
     SUMMARY OF INVENTION 
     The present invention relates to an entertainment system for use in vehicular applications that comprises a mounting system for securing a flat panel display. A mounting assembly is disclosed that comprises a front and a back panel that are rigidly coupled via an integrated cam latch comprising a plurality of matched interlocking extensions along one edge of each of the respective front and back panels. 
     It is an object of the present invention to provide an improved mounting system for display monitors for use in passenger vehicles. 
     It is a feature of the present invention to incorporate an interlocking cam latch for rigidly coupling the flat panel display assembly. 
     It is an advantage of the present invention that flat panel displays in passenger vehicles can be mounted to withstand incidental extreme forces without the permanent failure of the mounting system, while allowing for rapid replacement of the flat panel display from the housing assembly. 
     These and other objects, features, and advantages are disclosed in the specification, figures, and claims of the present invention.

     DETAILED DESCRIPTION 
     Referring now to the drawings wherein like numerals refer to like matter throughout, FIG. 1 is a perspective view of the display portion  100  of an on-board entertainment system incorporating the teachings of the present invention. As depicted, the display assembly  100  is comprised of a front panel  105  and a back panel  110  that surround, support and serve as mounting assembly for a flat panel display  115 . The entire display assembly is affixed to a convenient viewing surface  120 , such as a bulkhead or seatback, for intended viewers of the display. Although not shown, the display assembly is coupled to additional components of the entertainment system for receiving power and content signals. 
     FIG. 2 is an exploded view of one embodiment of a flat panel display housing system incorporating the advantages of the present invention. As depicted a flat panel display  205  is disposed between a front panel  210  and a back panel  215 , said panels having an exterior and interior surface, the flat panel arranged such that the interior surface of each of said front and back panels are adjacent to the primary surfaces of the flat panel display. 
     The front panel  210 , includes an opening  220  which provides viewing access to said flat panel  205  in the assembled display housing. The inside surface of front panel  210  includes a plurality of extensions  225  disposed along a first interior edge of said front panel  210 . Additionally, a plurality of structures  230  are provided, also on the inside surface of front panel  210  for supporting the flat panel  205  within the housing assembly. A recess  235  is also integrated into front panel  210 , shown on the opposite edge of the location of extensions  225 . 
     In a similar fashion back panel  215  is provided, having similar dimensions to front panel  210 , and each encompassing the perimeter of flat panel display  205 . The back panel further includes a plurality of extensions  240  for interlocking with the complementary extensions  225 . An integral tab  245  is provided along the opposite edge of the location of extensions  240  and proximately located for engaging recess  235 , when the front panel and back panel are coupled. Support structures  250 , shown in relief to indicate their location on the inside surface are also included on back panel  215  to support the flat panel display. The cam latch is created and engaged via the rotational assembly of the respective panels. In a preferred embodiment of the present invention, the edge of the panels which include the latch are located along the bottom portion of the display housing, thereby minimizing any exposed fasteners or connectors to vehicle passengers. 
     FIG. 3 is a perspective view of one embodiment of a portion of the latch assembly, illustrated in FIG.  2 . As shown, each location of the plurality of interlocking extensions  225  and  240  are contiguous to each other and form a latch, via the rotational coupling of the panels containing the latch. 
     It is understood that, while the detailed drawings, specific examples, and particular values given describe preferred exemplary embodiments of the present invention, they are for the purpose of illustration only. The apparatus and method of the present invention is not limited to the precise details of the conditions disclosed. Accordingly, changes may be made to the details disclosed without departing from the spirit of the invention the scope of which should be determined by the following claims.
