Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a cellular phone casing, and in particular to an improved cellular phone casing capable of storing a cellular phone (a mobile phone) from an external impact when a cellular phone is stored in a bag and is carried and capable of preventing a cellular phone from moisture in rain or at a beach.  
         [0003]     2. Description of the Background Art  
         [0004]     Generally, the size of a cellular phone is getting smaller and smaller for an easier carry. In addition, the weight of the same has been gradually decreased. For this reason, the casing of the cellular phone is generally made of a light plastic material. In this case, a LCD formed on a cover of a cellular phone is weak with respect to an external impact.  
         [0005]     In addition, in a carrying method of a cellular phone, in the case of many people, since the size of a cellular phone is small, and it is easy to carry in hand, the cellular phone is carried in hands or a certain strap connected with a connection ring of a cellular phone body is hung on a user&#39;s neck. In another method, the cellular phone is generally stored in a bag or a handbag.  
         [0006]     In addition, in the above cellular phone carrying method, in the case that the cellular phone is carried in hands, when a certain call comes in, a user can quickly pick up the cellular phone and can calls. However, in this case, there are many inconveniences to do another work with the remaining hand. Sometimes, the cellular phone may be dropped from hands, so that a big damage is given to the cellular phone.  
         [0007]     As one example, in some cases, in a state that a user holds a cellular phone in his hand, when the user needs to use hands, the user may forget the state that he holds a cellular phone in his hands and then may drop the cellular phone for thereby damaging the cellular phone. When the cellular phone is dropped from the hands, the casing of the cellular phone may be seriously damaged by an external impact, and the LCD may be broken.  
         [0008]     In addition, in the case that the neck strap is connected with the cellular phone and is hung on the user&#39;s neck, the cellular phone is not fixed, so that it may be swung. Namely, as the user walks, the cellular phone hung on the user&#39;s neck may be swung. When the user bends his upper body, the cellular phone hung on the user&#39;s neck may be downwardly extended and may hit the ground or the floor, so that the casing of the cellular phone may be damaged or the LCD may be broken.  
         [0009]     When the cellular phone is stored in the handbag or the bag and is carried, the cellular phone may collide with other items stored in the handbag or bag, so that the casing of the cellular phone may be scratched or the LCD may be scratched. A certain metallic item may contact with the terminals of the battery, so that fire may occur.  
         [0010]     In particular, when moisture penetrates into the electronic circuit, the cellular phone may become dead. Therefore, the users of the cellular phone should be careful about that water penetrates into the cellular phone. When it rains, the cellular phone cannot be held in hands. Namely, it should be stored in a safer place for thereby causing many inconveniences.  
         [0011]     As described above, since the cellular phone is weak with respect to moisture and water, it is impossible to carry the cellular phone at beach. Therefore, the cellular phone cannot be carried during the swimming. In the case that a certain emergency occurs during the swimming, it is impossible to use the cellular phone. Therefore, in the conventional art, it is impossible to efficiently cope with the emergency situation.  
         [0012]     In order to overcome the above problems, a certain cellular phone storing casing has been provided wherein it can be used at beach.  
         [0013]     However, since the conventional cellular phone storing casing is made of a vinyl bag that does not have strength, and an input portion of the vinyl bag is designed in a structure that it is opened and closed by a synthetic resin zipper. Therefore, in the case of the cellular phone storing casing formed of a vinyl bag, it is possible to slightly prevent the penetration of water, however the vinyl bag cannot protect the cellular phone from an external impact. In addition, the opening operation of the synthetic resin zipper is easier, however the closing operation of the opened zipper is not easy for thereby causing many inconveniences. In the case that the user swims in a state that the closed state of the synthetic resin zipper is not checked, water may penetrate into the interior of the cellular phone storing casing, so that a critical problem may occur in the cellular phone due to the penetrated water.

         [0041]     In the drawings, reference numeral  1  represents a cellular phone storing case. The cellular phone storing casing  1  includes a casing body  2 , a cover  3 , a locking part  4  and a hinge connection part  5 .  
         [0042]     The construction of the casing body  2  will be described.  
         [0043]     The casing body  2  is designed based on various cellular phones having different sizes and thickness. An inner storing space  21  is formed therein wherein an upper portion is opened. The inner storing space  21  has a certain size and depth for thereby storing the cellular phones (HP).  
         [0044]     In the casing body  2 , a protrusion rim  23  is formed below an opened rim upper portion  22 . At least one locking protrusion  24  is protruded from the protrusion rim at each of three surfaces including one surface opposite to the hinge connection part. In the present invention, the cellular phone storing casing  1  is formed in a rectangular shape because almost cellular phones HP are formed in rectangular shapes. Therefore, a plurality of locking protrusions  24  are formed in the left and right longitudinal sides of the casing body  2 . Preferably, two locking protrusions  24  are formed at each side. One locking protrusion  24  is protruded at one shorter side.  
         [0045]     In addition, a plurality of fixed hinges  25  are formed in the shorter sides in which the locking protrusions  24  are not formed in the casing body  2 . Each of the fixed hinges  25  is outwardly protruded from the protrusion rim  23  and includes a pair of opposite brackets  251 , and a pin shaft  252  connecting the same.  
         [0046]     The construction of the cover body  3  will be described.  
         [0047]     The cover body  3  includes an upper surface  31  having a certain size capable of covering the opened upper side of the casing body  2 , an outer rim  32  that is bent in the direction of the casing body  2  from the edges of the upper surface and is designed to cover the outer sides of the rim upper side  22  of the casing body, an inner rim  33  that is formed in an inner side of the outer rim for thereby surrounding the inner side of the rim upper side  22 , an engaging groove  34  formed between the inner and outer rims  32  and  33  for allowing the rim upper side  22  to be inserted, so that the cover body  3  is sealingly engaged with the upper side of the casing body  2 .  
         [0048]     In addition, the hinge part  35  is formed at the portion opposite to the locking protrusion  24  in the four sides of the outer rim  32  at the outer side of the cover body  3 . Locking wings  37   a ,  37   b  and  37   c  are connected at the hinge portions  35  in such a manner that the locking wings  37   a ,  37   b  and  37   c  are freely folded and unfolded with respect to the hinge line  36 . A locking hole  38  is formed at each locking wing wherein the locking holes  38  are detachably engaged with the locking protrusions  24  formed at each of three surfaces of the casing body  2 . The number of the locking holes  38  is determined based on the number of the locking protrusions  24 . In the present invention, two locking holes  38  are formed at two locking wings  37   a  and  37   b  that are longitudinally formed. One locking hole is formed at one shorter locking wing  37   c.    
         [0049]     In addition, a plurality of driving hinges  39  are downwardly extended from the edge portions of the outer rim in one surface in which the locking wings are not formed as one side of the outer rim  32  of the cover body  3 . In each driving hinge  39 , at least one hinge protrusion  391  is downwardly extended and is curved in such a manner that an end of the same forms a circle in the upward direction for thereby forming a J-shape. Preferably, the hinge protrusion  391  is formed at the center or at both sides of the same. The hinge protrusions  391  that form the driving hinges are inserted between the brackets  251  that are opposite between the fixed hinges  25  formed at the casing body  2  and are rotatable with respect to the pin shaft  252 . In addition, a support protrusion  392  is protruded between hinge protrusions  391  that form a plurality of driving hinges  39  for thereby supporting the upper side of the pin shaft  252 . Therefore, when each driving hinge  39  is assembled to each fixed hinge  25 , the hinge protrusions  391  surround the lower side of the pin shaft  252  and are assembled, and the support protrusions  392  rotatably support the upper side of the pin shaft  252 . Therefore, the driving hinge  39  is not loosened from the fixed hinge  25  when the cover body  3  is opened and closed.  
         [0050]     In addition, a sealing packing  40  is inserted into the engaging groove  34  formed between the inner and outer rims  33  and  32  of the cover body  3  in order for the cover body  3  to seal the casing body  2 . The sealing packing  40  is formed of a rubber material and has a fully filled cross section. In another embodiment of the present invention, it may have a hollow cross section. The sealing packing  40  has a better elasticity for thereby enhancing a sealing force of the cover body  3 . The sealing packing  40  having a hollow cross section is preferably used in order to protect the cellular phone from moisture or water.  
         [0051]     In the cellular phone storing casing  1 , a portable assistant strap  50  may be connected in a circular shape like a strap connected with the cellular phone thereby for achieving an easier carriage. In the present invention, a connection ring  60  having a connection hole  61  capable of connecting the portable assistant strap  50  is formed at one surface of the outer rim  32  in which the locking wings  37   a ,  37   b  and  37   c  are not formed in the cover body  3 . At this time, the connection ring  60  may be formed at either the cover body or the casing body of the surface in which the hinge connection part  5  is positioned or the opposite locking part is formed.  
         [0052]     A melted liquid flow disconnection hole  7  is formed along the hinge line  36  at the center between two locking holes  38  in order to prevent a welded line from being formed at the hinge line  36  that connects both locking wings  37   a  and  37   b  formed at the left and right sides in which the lengths of the outer rim  32  are longer when the injection is performed. The melted liquid flow disconnection hole  7  operates in such a manner that the melted liquid spreading in all directions when the plastic melted liquid is injected in the direction of the center of the upper surface  31  of the cover body  3  is not gathered at one portion but meets with the bodies of the locking wings  37   a  and  37   b . Therefore, the life span of each locking wing  36  is significantly extended since the welded line is not formed at the hinge line  36  based on the melted liquid flow disconnection hole  7 .  
         [0053]     The operation of the present invention will be described with reference to the accompanying drawings.  
         [0054]     The sealing engaged state by the locking part  4  should be released in order to uncover the cover body  3  engaged to the casing body  2 . When each locking wing  37   a ,  37   b  and  37   c  formed at three surfaces of the cover body  3  is released from each locking protrusion  24 , only the driving hinge  39  formed at one side of the outer rim  32  is rotatable with respect to the fixed hinge  25  of the casing body  2  in the cover body  3  as shown in  FIGS. 7 and 8 .  
         [0055]     Therefore, the user opens the cover body  3  (at this time, the cover body is rotated by the hinge connection parts  5  ( 25 ,  39 )) and is tilted in one side and opened), so that the user can store the cellular phone in the inner storing space  21  of the casing body  2 . After the cellular phone is stored, the cover body  3  is closed, and each locking wing  37   a ,  37   b  and  37   c  is rotated in the direction of the casing body  2 , and the locking protrusion  24  is inserted into the locking hole  38  formed at the locking wing. In this state, the cover body  3  fully covers the upper side of the casing body  2 . At this time, the sealing packing  40  disposed between the inner and outer rims  33  and  32  elastically compresses the rim upper side  22  of the casing body  2  by the engaging force of each locking wing. The above sealing state is continuously maintained until each locking wing  37   a ,  37   b  and  37   c  is released from the locking protrusion  24  of the casing body  2 .  
         [0056]      FIG. 9  is a view of the second embodiment of the present invention. As shown therein, the construction of the locking part  4   a  is different from the first embodiment of the present invention. An engaging groove  24   a  is formed at the lower side of the locking rim  24  protruded along the outer portion of the upper side of the casing body  2 , and the engaging protrusion  70  is protruded at the inner side of the locking wing  37   d  connected with the cover body  3  with the hinge line  35 . In the above state, when the locking wing  37  is pressed closer to the locking rim  24 , the end  70   a  of the engaging protrusion  70  moves over the lower surface of the locking rim  24  and is engaged to the engaging groove  24   a , so that the cover body  3  is sealingly engaged with the casing body  2 .  
         [0057]     Therefore, the engaging protrusion  70  is formed in a L-shape in which the end  70   a  is upwardly protruded in a horizontal state.  
         [0058]      FIG. 10  is a view of the third embodiment that the second embodiment of the present invention is modified. In this embodiment of the present invention, the locking wing  37   e  forming the locking part  4   b  is formed in a S-shape having a larger curve. The protrusion portion  70   b  protruded and curved in the inner direction of the locking wing  37   e  performs the operation like the engaging protrusion  70  of the first embodiment.  
         [0059]     The protrusion portion  70   b  corresponding to the engaging protrusion  70  has a slanted surface that is almost horizontal or slightly rises in the inner direction in its upper surface in a state that the locking wing  37   e  is locked, or an end portion of the same slightly rises in the upward direction. The protrusion portion  70   b  is caught by the lower surface  24   b  concaved in the locking rim  24  formed at the casing body  2 .  
         [0060]     The locking rim  24  is formed of a slanted surface or an upwardly concaved grove, so that the lower surface  24   b  can receive the upper end of the protrusion  70   b.    
         [0061]     In the case of the second embodiment of the present invention, when injecting the cover body  3 , an assistant core should be used due to the engaging protrusion  70 . In the case of the third embodiment of the present invention, since the locking wing  37   e  is formed in a S-shape and the inner portion of the body shares the function of the engaging protrusion, it is possible to fabricate without using the assistant core during the injection.  
         [0062]     In the present invention, in a state that the cellular phone HP is stored in the cellular phone storing casing  1  of which the cover body  3  is engaged to the casing body  2 , even when the cellular phone storing casing  1  is exposed to rain water while hanging the cellular phone on the neck using the portable assistant strap  50 , the rain water is not penetrated into the inner storing space  21  of the casing body  2 . In addition, even when the cellular phone gets wet in water at beach, it does not sink, so that water does not penetrate, and it is possible to protect the cellular phone stored in the cellular phone storing casing  1  from moisture and water.  
         [0063]     In addition, since the cellular phone HP stored in the cellular phone storing casing  1  is protected by the casing body  2  and the cover body  3 , when carrying the cellular phone in a state that the cellular phone is stored in the bag, the other items stored in the bag contact with the cellular phone storing casing  1  with no friction. Even when the cellular phone casing  1  is dropped on the floor or the ground, it is possible to absorb the impact for thereby effectively protecting the cellular phone HP. In addition, the cellular phone storing casing  1  may include a certain impact prevention material such as sponge, foamed resin, or foamed packing paper for thereby effectively absorbing and decreasing the impact. In another embodiment of the present invention, an impact prevention material may cover and store the cellular phone, so that it is possible to more effectively protect the cellular phone HP.  
         [0064]     As described above, in the present invention, when various kinds of cellular phones used by many people are stored in the cellular phone storing casing according to the present invention, it is possible to easily hear the incoming signals of the cellular phone. In the manner mode, it is possible to easily recognize the vibration sound or vibration, so that there is not any problem in the use of cellular phone. Even when the user drops the cellular phone storing casing onto the floor or the ground, it is possible to safely protect the cellular phone. In addition, even when the cellular phone casing is exposed in rain, rainwater does not penetrate into the interior having the cellular phone therein. If the cellular phone storing casing is dropped into water, the interior of the same is fully sealed for thereby preventing the penetration of water thereinto. Therefore, in the present invention, it is possible to safely store the cellular phone in the cellular phone storing casing, so that a n emergency call may be made at the outdoor or at beach. When an emergency situation occurs, it is possible to send a rescue call using the cellular phone.  
         [0065]     As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
