CLAIM OF PRIORITY 
       [0001]    This application claims the benefit under 35 U.S.C. §119(a) of a Korean Patent Application filed in the Korean Intellectual Property Office on Nov. 27, 2008 and assigned Serial No. 10-2008-0118613, the entire disclosure of which is hereby incorporated by reference in its entirety. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to an S.O.S. (“Save Our Ship”, e.g. emergency) cover opening and shutting apparatus for a portable terminal, capable of allowing a user to access an emergency call service, or an S.O.S. service. 
         [0004]    2. Description of the Related Art 
         [0005]    Recently, a variety of functions have been added to portable terminals to meet various demands of users. In particular, the multimedia functions for delivering image data as well are currently the most popular—and include such functions as e-mail, Internet, games and the like based on portable terminals—which are also added/updated on a regular basis. 
         [0006]    Such portable terminals periodically communicate with a base station in the area where they are presently located, to inform/update the base station of their current locations, thereby enabling calls to be seamlessly received. When the portable terminals are relocated by vehicles or walking, the portable terminals often switch communication from the current base station to a new base station in the area to which they are going to move, if the relocation crosses into an area better handled by a new/different base station. 
         [0007]    In our very complex and free society, users of portable terminals can be exposed to many dangers. For example, many emergency situations may happen, in which users are threatened, injured, kidnapped by suspicious fellows, meet with a disaster by a fire or lost in the mountains, or are locked in airtight spaces, just to name a few of the potential dangers that are the subject of media reporting. Conventionally, when these emergency situations occur, the users of portable terminals generally make a call directly using the portable terminals to inform an acquaintance, police, a relief squad or the like of the emergency situations. In most cases, however, the users may have difficulty in making a call in the emergency situations to inform the emergency situations. For example, in the United States, dialing  911  from a wireless telephone will generally forward your call to an emergency center closest to a particular base station. However, the system is not perfect and sometimes the closest emergency responders are not the ones notified via the  911  system. 
         [0008]    Many portable terminals now enable users to notify responders of their emergency situation/status to a previously registered portable terminal(s) by manipulating an input means such as an emergency button provided on the portable terminals when crimes or emergency disasters happen. In this case, however, an unnecessary S.O.S. service may occasionally be activated by user&#39;s mismanipulation. Then, a user of the portable terminal receiving the unnecessary call or message may be placed into a difficult situation, which may give an unpleasant feeling to the user of the receiving portable terminal. In addition, one might say they accidentally pushed the button because an assailant is threatening them with immediate bodily harm unless they lie to the responder and say that the activation of the button was an accident. 
         [0009]    Therefore, the conventional portable terminal has limitations on the environments in which the user can inform a responder of an emergency situation, and thus, the user may have difficulty in asking surrounding people for a help without mismanipulation. 
       SUMMARY OF THE INVENTION 
       [0010]    An aspect of the present invention provides an S.O.S. cover opening and shutting apparatus for a portable terminal, capable of offering an efficient operation of an S.O.S. service informing user&#39;s emergency situations, by slidable activation. The act of slidingly moving an S.O.S. cover of the portable terminal activates the function of contacting the emergency services, and at the same time has a lower rate of accidental activations when compared to keypad button type emergency actuators. 
         [0011]    Another exemplary aspect of the present invention provides an S.O.S. cover opening and shutting apparatus for a portable terminal, capable of providing a differentiated design by making an S.O.S. cover of the portable terminal such that it can be slidingly moved to activate an emergency notification. 
         [0012]    Furthermore, another exemplary aspect of the present invention provides an S.O.S. cover opening and shutting apparatus for a portable terminal, which provides a stopper capable of stopping a sliding movement of an S.O.S. cover, and has a separate protrusion to offer a “click” sensation so that a user can feel the sliding movement. 
         [0013]    Yet another exemplary aspect of the present invention provides an S.O.S. cover opening and shutting apparatus for a portable terminal, capable of preventing misuse of an S.O.S. service due to user&#39;s mismanipulation by enabling the user to simply manipulate or implement the S.O.S. service of the portable terminal. 
         [0014]    According to still another exemplary aspect of the present invention, there is provided an S.O.S. cover opening and shutting apparatus for a portable terminal. The apparatus includes an S.O.S. cover for opening and closing a part of the portable terminal by a sliding movement; a rear case in which the S.O.S. cover is settled; and a bracket fixedly coupled to the S.O.S. cover to approve movement of the S.O.S. cover only in a predetermined section. 
         [0015]    Preferably, the S.O.S. cover may include an S.O.S. contact contacting a sensor contact provided on a sensor in a body to implement an S.O.S. service when the S.O.S. cover slidingly moves. 
         [0016]    Other exemplary aspects, advantages, and salient features of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses exemplary embodiments of the invention.

       DETAILED DESCRIPTION 
       [0034]    The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary and provided for illustrative purposes the claimed invention is not limited to the examples shown and described. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the exemplary embodiments described herein can be made without departing from spirit of the invention and the scope of the appended claims. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness when their inclusion could obscure appreciation of the subject matter of the present invention by a person of ordinary skill in the art. 
         [0035]    The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents. 
         [0036]    It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces. 
         [0037]      FIGS. 1 and 2  illustrate a rear side of a portable terminal. More specifically,  FIG. 1  illustrates a state in which an S.O.S. cover  100  is shut as it is fixed to a rear case  200 , which is a rear side of a body of a portable terminal, and  FIG. 2  illustrates the state in which the S.O.S. cover  100  is open as it is slidingly moved in the state where the S.O.S. cover  100  is fixed to the rear case  200 . The S.O.S. cover  100  should not necessarily be formed on the rear side of the body of the portable terminal as illustrated in  FIGS. 1 and 2 . Instead of being arranged as shown, the S.O.S. cover  100  may be formed on a front side or a flank side, etc. of the portable terminal. 
         [0038]    Portable terminals can be generally classified into flip-type terminals, folder-type terminals, bar-type terminals, sliding-type terminals and so forth according to their appearance and/or operational manner. The present invention can be applied to at least all of the above types of the portable terminals. 
         [0039]    Although a mobile communication terminal is given herein as a typical example of a portable terminal according to an exemplary embodiment of the present invention, it is not intended to limit the scope of the present invention to the mobile communication terminal, and the present invention can be applied to various other types of portable terminals. 
         [0040]    For example, portable terminals according to an exemplary embodiment of the present invention may include all information technology devices, multimedia devices and their associated application devices, such as a Portable Multimedia Player (PMP), an MP3 player, a digital broadcasting player, Personal Digital Assistant (PDA) and smart phone, including all mobile communication terminals operating based on communication protocols corresponding to various communication systems, just to name a few possibilities. 
         [0041]      FIG. 3  schematically illustrates how to assemble an S.O.S. cover  100  in a portable terminal according to an exemplary embodiment of the present invention. Referring now to  FIG. 3 , the portable terminal includes an S.O.S. cover  100  that a user may slidingly move via a manual operation, a rear case  200  in which the S.O.S. cover  100  is to be arranged, and a bracket  300  serving as a stopper, fixed to the S.O.S. cover  100  by screws  400  so that the S.O.S. cover  100  may not be detached from the portable terminal when the S.O.S. cover  100  is slidingly moved. 
         [0042]    Thus, when the user slidingly moves the S.O.S. cover  100 , the S.O.S. cover  100  will slidingly move together with the bracket  300  and stay attached to the portable terminal. 
         [0043]      FIG. 4A  illustrates a front side of the S.O.S. cover  100  having a lock  101  for allowing the user to readily attach and detach the S.O.S. cover  100  to/from the portable terminal. 
         [0044]      FIG. 4B  illustrates an inside of the S.O.S. cover  100  that has screw fixing holes  102  for fixing the bracket  300 , and a protrusion  103 , formed on a lower portion of the S.O.S. cover  100 , which serves to give a click feeling to the user when the S.O.S. cover  100  slidingly moves, to prevent the S.O.S. cover  100  from freely moving, and to fix the S.O.S. cover  100  to the rear case  200  in a safe state. The protrusion  103  will be described below in more detail. For example, the protrusion  103  may be formed by making a projection on an injection-molded product, or by putting a separate metal plate on the injection-molded product. 
         [0045]    In addition, the S.O.S. cover  100  in  FIG. 4B  has separate S.O.S. contacts  106  that is linked to a circuit part to inform the user&#39;s emergency situations by slidingly moving the S.O.S. cover  100 , or to output a separate emergency alarm sound by the portable terminal. The S.O.S. contacts  106  will be described in connection with other drawings. 
         [0046]      FIG. 4C  illustrates a side of the S.O.S. cover  100  having separate guides  204  that are coupled to the rear case  200  to prevent left/right swinging (free moving) against the rear case  200  during a sliding movement. The guides  204  are fit into sliding grooves  207  formed on the rear case  200 , inducing the sliding movement. Further, the S.O.S. cover  100  ( FIG. 4B ) has          -shaped (i.e. “L-shaped”) hooks  105  coupled to the rear case  200  to prevent up/down swinging during a sliding movement. 
         [0047]      FIG. 5  illustrates an inside area of the rear case  200  of an exemplary portable terminal. The rear case  200  has first and second case protrusions  201  and  202  for providing a clicking sensation to the user when the S.O.S. cover  100  slidingly moves so that the protrusions  201 ,  202  contact the protrusion  103  on the S.O.S. cover  100 , and also has a sliding support  203  along which the bracket  300  screwed to the S.O.S. cover  100  may be slidingly moved, in which bracket  300  and support  203  comprise a bracket assembly  300   a  ( FIG. 7B ). Further, the rear case  200  has          -shaped guide protrusions  204  which are fit into the          -shaped hooks  105  on the S.O.S. cover  100  in the opposite direction to prevent up/down swinging. The rear case  200  has sliding grooves  207  into which the guides  104  on the S.O.S. cover  100  are inserted, inducing the sliding movement. 
         [0048]      FIG. 6  illustrates a side elevation view in a state where the S.O.S. cover  100  is coupled to the rear case  200 . The S.O.S. cover  100  has the S.O.S. contacts  106  that generate electrical signals when the S.O.S. cover  100  slidingly moves. The          -shaped guide protrusions  204  are formed even on the rear case  200  in association with the          -shaped hooks  105  on the S.O.S. cover  100  in order to prevent up/down swinging generated when the S.O.S. cover  100  slidingly moves. The number of the hooks  105  and the guide protrusions  204  is subject to change according to a size of the portable terminal. 
         [0049]      FIG. 7A  illustrates a rear side of a portable terminal in a state where the S.O.S. cover  100 , which is coupled to the rear case  200 , has not slidingly moved.  FIG. 7B  illustrates an inside of the rear case  200  in  FIG. 7A . In  FIG. 7B , the bracket  300  is fixed by screws  400 .  FIG. 7C  is a cross sectional view of  FIG. 7A , showing a safe state in which the S.O.S. cover  100  may not be easily slid since the protrusion  103  on the S.O.S. cover  100  is hooked by the first case protrusion  201  on the rear case  200 . 
         [0050]      FIGS. 8A and 8B  illustrate the outward appearance of the rear side and the rear case  200  of the portable terminal in a state where the S.O.S. cover  100 , which is coupled to the rear case  200 , has slidingly moved. When  FIG. 8B  is compared with  FIG. 7B , it can be appreciated that a location of the bracket  300  has moved from the lower portion in the state of  FIG. 7B  to the upper portion in the state of  FIG. 8B  as the S.O.S. cover  100  has slidingly moved. 
         [0051]    Furthermore, in  FIG. 8B , the bracket  300  may serve as a stopper that prevents the S.O.S. cover  100  from being detached from the portable terminal as it contacts an end of the sliding support  203  on the rear case  200 .  FIG. 8C  is a cross sectional view of  FIG. 8A , and when it is compared with  FIG. 7C , the protrusion  103  on the S.O.S. cover  100  has moved from the location of the first case protrusion  201  on the rear case  200  to the second case protrusion  202  by the sliding movement. If the protrusion  103  on the S.O.S. cover  100  contacts the first and second case protrusions  201  and  202  on the rear case  200  by the sliding movement, a click feeling may be provided to the user and the S.O.S. cover  100  can be prevented from being easily slid, as a certain degree of force is necessary to cause the protrusion  103  to slide over the first protrusion  201 . 
         [0052]      FIGS. 9A and 9B  illustrate how the S.O.S. contact  106  formed on the guide  104  of the S.O.S. cover  100  contacts a sensor contact  501  provided on a sensor  500  in a body of the portable terminal. While the S.O.S. cover  100  slidingly moves from the state of  FIG. 9A  to the state of  FIG. 9B , the S.O.S. contact  106  contacts the sensor contact  501 , activating the S.O.S. service. That is, the S.O.S. service is a service that sends an emergency message to a previously registered phone number(s) and/or generates an emergency alarm sound by the user. 
         [0053]      FIG. 10  illustrates a circuit diagram for implementing an S.O.S. service when an S.O.S. cover slidingly moves, according to an embodiment of the present invention. The S.O.S. service is implemented or activated by the sliding movement of the S.O.S. cover  100 . Referring now to  FIGS. 9A ,  9 B and  10 , in operation, as the S.O.S. cover  100  slidingly moves, the S.O.S. contact  106  touches the sensor contact  501  provided on the sensor  500  in the body of the portable terminal. When the S.O.S. contact  106  touches the sensor contact  501 , the sensor  500  senses the touch of the sensor contact  501 , generates an electrical signal and applies the electrical signal to a controller  600 , which implements the S.O.S. service. The controller  600  controls a transmitter  700  to deliver the S.O.S. service to a phone number the user already registered, to which he/she intends to notify the emergency situations, and also controls a speaker  800  to generate an S.O.S. alarm sound. 
         [0054]    While the invention has been shown and described with reference to a certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents. For example, while in the exemplary embodiments disclose above the S.O.S. cover moves, it is within the spirit of the invention and the scope of the appended claims that the S.O.S. cover could clickably slides along an exterior of the S.O.S cover to, for example, activate a switch such as switch  501  shown in  FIGS. 9A and 9B . Also, only a portion of S.O.S. cover might move. In addition, while one exemplary switch  501  associated with a predetermined emergency contact is shown, it is also within the spirit and scope of the invention to either provide a plurality of switches, or an optical sensor and a series of marks (or reflective material) and/or a magnetic means, so that a position of a lower portion of S.O.S. cover in the vicinity of contact  106  can be sensed to activate an emergency call. Also, a pressure switch could be used, whereby squeezing the S.O.S. cover activates an emergency call. In addition, for example, it is also within the spirit and scope of the invention that although the examples show one switch and one S.O.S. emergency contact, there could be more than one emergency contact based on the position the cover is clickably slid to in the event of an emergency. 
         [0055]    In addition, while the exemplary bracket shows being affixed to the S.O.S. cover via screws, we note that a person of ordinary skill in the art understands and appreciate that the any type of coupling that permits the invention to operate as intended could be used. For example, instead of screws, nuts and bolts, clips, pins, welds, snap fit male-female interconnections and bonding are just a few possible examples of how the cover and bracket could be coupled.
