     BACKGROUND OF THE INVENTION 
     In contemporary computers such as iMac computers manufactured by Apple Computer, Inc. of Cupertino, Calif., most of the critical components, such as the motherboard, memory, etc., are enclosed within a small interior space. Modification, upgrading and repair of such a computer requires access to the components within this interior space, which is enclosed on all sides. In the case of the iMac computer, for example, the interior components are accessed by means of case screws. A Phillips screwdriver or a tool provided by the computer manufacturer is needed in order to turn these screws, and they must be turned in and then not removed, in accordance with the manufacturer&#39;s instructions. Once the screws have been turned in accordance with the manufacturer&#39;s instructions, the case of the computer can then be opened to access the interior components. 
     Other computers may require a different tool to open the case, and there may be different manufacturers&#39; instructions, but in each instance a specific tool is required to open the case and manufacturer&#39;s instructions must be followed. If the customer or repair person does not have the correct tool, uses too much force, or does not otherwise follow the manufacturer&#39;s instructions, the case of the computer may be damaged or may not be possible to open. Also, such tools, which could include different kinds of screwdrivers, keys, or custom tools, are easily lost or misplaced, in which case a replacement tool must be ordered, further causing a delay in repair or upgrading of the computer. 
     Accordingly, what is needed is a method and system for opening a device easily and quickly, without the possibility of damage to the computer, display, or device. The method and system should be easily implemented, adaptable and cost-effective. The present invention addresses such a need. 
     SUMMARY OF THE INVENTION 
     A latching mechanism for a device is disclosed. The device includes a first member and a second member. The latching mechanism comprises one or more protruding members coupled to an interior of the device. The one or more protruding members is coupled to one of the first member and the second member. The latching mechanism includes one or more latches coupled to an interior portion of the device. The one or more latches are coupled to the other of the first and second members. The one or more latches is engageably coupled to the one or more protruding members when the first and second are coupled together.

Although the latches and boss members are coupled to the bezel and rear cover respectively in this embodiment one of ordinary skill in the art readily recognizes that the coupling could be reversed or varied and there use would be within the spirit and scope of the present invention. Furthermore it is readily understood by one of ordinary skill in the art that a variety of enclosures could be utilized to that have more than one member coupled together and there use would be within the spirit and scope of the present invention. Latches  202  and  202   b  include a metal that is attracted to a magnetic force. The latches in a preferred embodiment are made of steel like material. This is utilized to advantage to allow the rear cover to be disengaged from the bezel  104  without the use of external fasteners. To illustrate this feature refer now to  FIG. 2A . 
       FIG. 2A  illustrates the same view of the latching system of  FIG. 2  except that the latching mechanism  200   a  is disengaged. By placing a magnet  206  exterior to the computer  100  the latch  202   a  is released from the boss member  204   a  allowing for the rear cover  102  and the bezel  104  to be disengaged. 
       FIG. 3  is a blown up view of the latch  202   a  shown of  FIG. 2A . As is seen the magnet  206  has pulled the latch  202   a  downward, causing the latch  202   a  to disengage from the boss member  204   a.    
       FIG. 4  is a perspective view of an embodiment of the latch  202  in accordance with the present invention. The latch  202  includes a body portion  402  which is coupled to the bezel  102 . The latch  202  includes a latch portion  404  coupled to the body portion  402  and a hinge  406  which allows for the up and down movement of the latch portion. There is also a space  408  between the latch  202  and the body portion  402  for allowing the rear cover to be placed therebetween. 
       FIG. 5  is a perspective view of the bezel  104 . The latch  202  is coupled internal to the bezel  104 . The body portion  402  is attached to the bezel preferably by an adhesive.  FIG. 6  is a cut-away perspective view of the computer  100  with the rear cover and the bezel engaged with each other. 
       FIG. 7  is a perspective cut-away perspective view of the rear cover  104  and the bezel  102  with the bezel  102  disengaged from the rear cover  104 . As is seen rear cover  104  would fit between the body portion  402  and the latch portion of the latch  202  when the rear cover  104  is inserted into the bezel  102 . 
     A latching system is provided for coupling together the members which house the interior components of a device. The latching system includes at least one latching mechanism which can be released through the use of a magnet exterior to the device thereby allowing for the decoupling of the members which house the interior components. In so doing, a tool such as a screwdriver or the like is not required to decouple the members. 
     Although the combination magnet and release latch mechanism in accordance with the present invention is shown with the preferred embodiment of a computer, one of ordinary skill in the art recognizes that such a release mechanism could also be used for other kinds of electronic or mechanical components which require an interior compartment to be accessed without the use of conventional tools such as a screwdriver or special key. 
     Although the present invention has been described in accordance with the embodiments shown, one of ordinary skill in the art will readily recognize that there could be variations to the embodiments and those variations would be within the spirit and scope of the present invention. Accordingly, many modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims.
