Description




BACKGROUND




The disclosures herein relate generally to a computer system and more particularly to the arrangement of components in a computer system chasis.




Today's customers are asking for smaller chassis enclosures without giving up performance or serviceability. The components inside the chassis are not getting smaller and in some cases growing larger. The problem is to more efficiently package components and still maintain a high level of manufacturability and serviceability.




Today's chassis are about 50% volume efficient. In every desktop chassis today, extra room is left inside the chassis for hand/access room for manufacturing and service. This extra room creates larger chassis than customers are demanding and drives up shipping and material cost for the larger enclosures.




Therefore, what is needed is a computer chassis that is not oversized and can compactly house all of the computer components for easy access.




SUMMARY




One embodiment, accordingly, provides a swing-open computer chassis. To this end, a computer chassis includes a base portion formed of a metal chassis and a cosmetic cover. A top portion of the chassis is formed of a metal chassis and a cosmetic cover. A plurality of first computer components are mounted in the base portion. A plurality of second computer components are mounted in the top portion. A pivotal connection is provided between the top portion and the base portion. The top portion is pivotable about 90° relative to the base portion to an open position immediately exposing all of the first and second computer components for access, without removing any of the cosmetic covers.




A principal advantage of this embodiment is that the computer chassis size is maintained due to the compact positioning of components in the top and base chassis portions. The open chassis provides for top down assembly and total system access. The chassis may be opened and closed without removing any of the cosmetic covers.

A chassis


26


,

FIG. 2

, is provided to support all or most of the components of system


10


, as set forth above. Chassis


26


includes a base portion


28


formed of a metal portion


30


and an outer plastic cosmetic cover


32


. A top portion


34


of chassis


26


is pivotally connected to base portion


28


at a hinge connection generally designated


36


. Top portion


34


includes a metal portion


38


and an outer plastic cosmetic cover


40


. The base portion


28


includes a base surface


42


. The cosmetic cover


40


includes a top surface


46


and an endwall


48


. The base portion


28


forms part of a cavity


50


in chassis


26


for containing a plurality of first computer components


52


, and the top portion


34


forms another part of the cavity


50


for containing a plurality of second computer components


54


.




The hinge connection


36


permits the top portion


34


to pivot to an open position


0


about 90° relative to base portion


28


, and to pivot to a closed position C,

FIG. 3

, wherein the top portion


34


and base portion nest together to define the cavity


50


. It is understood that the open position


0


may be more or less than 90° as desired.




A pair of side panels


72


,

FIGS. 3 and 4

, of top cosmetic cover


40


are configured to nest with a complimentary configured pair of side panels


74


of base cosmetic cover


32


when chassis


26


is in the closed position C. When closed, the top portion


34


is automatically secured to the bottom portion


28


by a releasable latch


56


, extending from each side panel


72


of top portion


34


, which includes a latch member


56




a


and a release button


56




b


which permits latch member

attached to base portion


28


. A groove


60


in guides


58


receives a pin


62


attached to top portion


34


for sliding movement in grooves


60


.




First components


52


,

FIG. 5

, are positioned in base portion


28


, and second components


54


are positioned in top portion


34


so that when chassis


26


is closed, a void area


50




a


of cavity


50


in top portion


34


, is filled with first components


52


. Likewise, a void area


50




b


of cavity


50


in base portion


28


, is filled with second components


54


. In this manner, when chassis


26


is closed, first components


52


are nested side-by-side with second components


54


. This also ensures that when chassis


26


is opened, access to components


52


,


54


is enhanced, and when chassis


26


is closed, space in cavity


50


is maximally utilized. For example, second components


54


in top portion


34


are positioned adjacent a fan


61


in base portion


28


for cooling, thus enhancing the mutually complimentary arrangement of components in chassis


50


. Furthermore, when chassis


50


is opened, there is no requirement to remove any cosmetic covers from the metal chassis frame, only disengagement of latch


56


is required.




As a result, one embodiment provides a computer chassis comprising a base portion formed of a metal chassis and a cosmetic cover; a top portion formed of a metal chassis and a cosmetic cover; a plurality of first computer components mounted in the base portion; a plurality of second computer components mounted in the top portion; a pivotal connection between the top portion and the base portion; and the top portion being pivotable relative to the base portion to an open position immediately exposing all of the first and second computer components for access, without removing any of the cosmetic covers.




Another embodiment provides a computer chassis comprising a base portion including a base surface and an integral end wall formed of a metal chassis and a cosmetic cover; a top portion including a top surface and an integral end wall formed of a metal chassis and a cosmetic cover; a plurality of first computer components mounted in the base portion; a plurality of second computer components mounted in the top portion; and a pivotal connection between the top portion and the base portion, whereby a single pivotable movement of the top portion and its integral end wall relative to the base portion to an open position, immediately exposes all of the first and second computer components for access, without removing any of the cosmetic covers.




A further embodiment provides a computer system comprising a chassis having an internal computer component cavity defined therein; a microprocessor mounted in the chassis; a storage coupled to the microprocessor; a video controller coupled to the microprocessor; a memory coupled to provide storage to facilitate execution of computer programs by the microprocessor; a base portion of the chassis formed of a metal portion and a cosmetic cover; a top portion of the chassis formed of a metal portion and a cosmetic cover; a plurality of first computer components mounted in the base portion; a plurality of second computer components mounted in the top portion; a pivotal connection between the top portion and the base portion; and the top portion being pivotable relative to the base portion to an open position immediately exposing the cavity and the plurality of first and second computer components for access, without removing any of the cosmetic covers.




As can be seen, the principal advantages of these embodiments are that this device creates an extremely open frame chassis that gives manufacturing and service technicians more access room than typical desktop chassis. Once the chassis is closed, it allows components to be nested closer together creating a smaller denser chassis enclosure. The enclosure opens by moving the top cover and front wall of the chassis forward to about 90 degrees from the original orientation. This creates the open enclosure that allows 100% top down assembly in manufacturing. The top opens with the outer plastic cosmetic cover on the metal frame. This ability is drastically different and time saving than any other or previous chassis available. The metal chassis top and cosmetic cover no longer need to be removed to manufacture or service the chassis. Instead of removing the metal top and the cosmetic cover, the operator pivots the top to the open position allowing direct access to all components.




Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiment may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein.
