Title: Display protection film attatching case for mobile terminal

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a case for attaching a screen protector film for a mobile terminal and, more particularly, to a case that allows for quick and easy attachment of a screen protector film for a mobile terminal. 
     2. Description of the Related Art 
     The screens of smart-phone and tablet PCs that are recently widely used are more expensive and larger than those of common mobile phones, so screen protector films are attached and used to prevent scratches. 
     Screen protector films are generally composed of a transparent plastic film having an adhesive bottom and a separation film detachably disposed on the plastic film to protect the adhesive bottom. 
     In common mobile phones, the screens are a small square or rectangle and, a keypad, a speaker, and a camera are disposed not on, but around the screens, so a screen protector film can he easily attached by folding and separating the separation film. 
     In smartphones or tablet PCs that have been popularized and widely used in recent years, a camera lens, a speaker, a home button, and various sensors are disposed in the screens, so screen protector films are manufactured and sold with the portions for the camera lens etc. are cut and bored to be appropriately attached. 
     When attaching a screen protector film to a smartphone or a tablet PC, a user should put the cut and bored portions over the camera lens, a speaker, a home button, and various sensors. 
     However, the screens of the smartphones and tablet PCs are larger than those of common mobile phones, and bored portions and cut portions are positioned over and under each other, so it is difficult to attach a screen protector film at an exact position at a time. 
     In particular, one label is attached to the separation film on the rear sides of screen protector films that are on the market, so a user has to holds and pull the label in one direction with a screen protector film on a screen to separate the separation film, whereby it is difficult to attach the screen protector film at an exact position inside the screen. 
     If a screen protector film is not attached at an exact position at a time, the screen protector film is attached aslant. When a screen protector film attached aslant is detached, dirt adheres to the adhesive side or the adhesive side is damaged by fingerprints or trace of fingers, so transparency is deteriorated. Further, when the adhesive side is damaged, the adhesion is deteriorated. 
     Accordingly, it is required to exactly attach a screen protector film at a time to a mobile terminal, so it is very difficult to attach a screen protector film. Further, when a screen protector film is not attached at a time, the screen protector film is damaged and new screen protector films are needed in many cases.

     Referring to  FIGS. 1 and 2 , a case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention includes a film housing  100  and a movable member  200 . 
     The film housing  100  provides a space for keeping a screen protector  10 . To this end, the film housing  100  may have a bottom  110 , sides  120 , and a film seat  130 . The bottom  100  may be a rectangular plate and the sides  120  may perpendicularly extend from the edges of the bottom  110 . The film seat  130  is formed on the inner side of the bottom  110 . For example, the film seat  130  may be recessed from the inner side of the bottom  110  to be lower than the inner side of the bottom  110 . 
     The screen protector  10 . that is disposed in the film seat  130  may include a separation film  11  and a screen protector film  12  that is separated from the separation film  11  to be attached to the screen of a mobile terminal. The screen protector  10  is kept in the screen seat  130  with the screen protector film  12  up. 
     The movable member  200  has a cover portion  210  that is combined with the film housing  100  and covers the insides of the sides  120  of the film housing  100 . The cover portion  210  may be a rectangular plate that is the same as or larger in size than the bottom  110 . The edges of the inner side of the cover portion  210  correspond to the top of the sides  120  of the film housing  100  when the movable member  200  is moved in a predetermined movement direction. 
     The movable member  200  is slidably coupled to the film housing  100 . To this end, the film housing  100  may have a pair of guide walls  140  and the movable member  200  may include a pair of sliding walls  220 . 
     The pair of guide walls  140  may be disposed close to a short side of the bottom  110  of the film housing  100 , that is, the upper end of the bottom  110  when the inner side of the bottom  110  is seen from the front. In order to form the pair of guide walls  140 , it may be possible to open the inside from the sides  120  by cutting portions of the side  120  of the film housing  100  and form the pair of guide walls  140  at both sides of the open portions of the sides  120 . The pair of guide walls  140  is spaced at a predetermined distance to face each other and extend parallel with the longitudinal direction of the bottom  110 . The extended length of the pair of guides  140  is not specifically limited and they may be short, as shown in FIG.  1 . A guide groove  141  may be formed on the inner sides of the pair of guide walls  140 . 
     The pair of sliding walls  220  protrudes downward from the inner side of the cover portion  210  of the movable member  200  and extends a predetermined distance in the longitudinal direction of the cover portion  210 . The pair of sliding wails  220  is spaced at a predetermined distance to face each other. The distance between, the pair of guide walls  140  may be the distance between the guide walls  140 . A guide protrusion  221  may be formed on the inner sides of the pair of sliding walls  220 . The guide protrusions  221  are inserted in the guide grooves  141  formed on the pair of guide walls  140  to enable the pair of sliding walls  220  to stably slide in contact with the pair of guide walls  140  without separating from the pair of guide walls  140 . 
     By the pair of guide walls  140  and the pair of sliding walls  220 , the movable member  200  is coupled to or separated from the film housing  100  by sliding the movable member  200  in a movement direction parallel with the longitudinal direction of the screen protector  10  kept in the film housing  100  and the longitudinal direction of the film housing  100 . 
     When the movable member  200  combined with the film housing  100  is moved to be separated from the film housing  100 , the screen protector film  12  of the screen protector  10  kept in the film seat  130  is gradually separated from the separation film  11  to be attached to the screen of a mobile terminal  30 . To this end, the movable member  200  has a terminal seat  230  and a predetermined portion around the terminal seat  230  is connected to the screen protector film  12 . 
     The terminal seat  230  is a portion that corresponds to the upper end or the lower end of the mobile terminal  30  and allows the movable member  200  to move in the movement direction when the mobile terminal  30  is pushed toward the terminal seat  230 . The terminal seat  230  is positioned at an end perpendicular in the movement direction of the movable member  200 , that is, the lower end of the cover portion  210  of the movable member  200 . The terminal seat  230  may have a curved portion  231 , a pushing projection  232 , and a pair of guides  233 . 
     The curved portion  231  can keep the upper end or the lower end of the mobile terminal  30 . To this end, the curved portion  231  may be formed in a shape corresponding to the shape of the upper end of the mobile terminal  30 . The curved portion  231  may be formed inward from the lower end of the cover portion  210  of the movable member  200 . 
     The pushing protrusion  232  may be a plate perpendicularly protruding from the end of the curved portion  231  and is positioned at the center of the curved portion  231 . When the upper end or the lower end of the mobile terminal  30  is inserted in the curved portion  231 , the pushing protrusion  232  may corresponding to the center of the upper end or the lower end of the mobile terminal  30 . 
     The pair of guides  233  may be plate perpendicularly protruding from the end of the curved portion  232  and are disposed at the left and right sides from the pushing protrusion  232 . When the upper end or the lower end of the mobile terminal  30  is inserted in the curved portion  231 , the pair of guides  233  correspond to the corners of the upper end or the lower end of the mobile terminal  30 , so they can guide the upper end or the lower end of the mobile terminal  30  to be easily inserted into the curved portion  231 . 
     The areas that are connected to the screen protector film  12  may be the areas between the pushing protrusion  232  and the guides  233 . For example, the screen protector film  12  may be connected to the movable member  200  through a sheet-like tag  20  attached to the side opposite to the side with the separation film  11  thereon. In this case, the end of the tag  20  may be attached to the outer side of the cover portion  210  between the pushing protrusion  232  and the guides  233 . For example, the tag  20  may be bonded to the outer side of the cover portion  210  by a double-sided tape. As the movable member  200  is moved to be separated from the film housing  100 , the tag  20  is pulled, whereby the connected screen protector film  12  can be separated from the separation film  11 . 
     On the other hand, the film housing  100  may further have a pair of cover supports  150  and the movable member  200  may further have a film-pressing side  240 . 
     The pair of cover supports  150  is disposed close to the film seat  130  of the film housing  100  and support the cover portion  210  while the movable member  200  is moved in the movement direction. To this end, the pair of cover supports  150  extends parallel with the movement direction of the movable member  200 . For example, the cover supports  150  may extend toward the lower end of the film housing  100  from the pair of guide walls  140 . The pair of cover supports  150  may extend the movement distance of the movable member  200  and have a predetermined width. The inner side of the cover portion  210  of the movable member  200  is supported by the cover supports  150 . 
     The film-pressing side  240  presses the screen protector  10  kept in the film seat  130  while the movable member  200  is moved in the movement direction. The film-pressing side  240  may be disposed between the pair of sliding walls  220 . For example, the film-pressing side  240  may be a flat surface that can be integrated with the pair of sliding walls  220  by connecting the edges to the ends of the sliding walls  220 . In this case, the film-pressing side  240  faces the film seat  130 . The film-pressing side  240  is in contact with the inner side of the bottom  110  of the film housing  100  when the movable member  200  is combined with the film housing  100 , and accordingly, when the screen protector  10  is placed in the film seat  130 , the film-pressing side  240  may can be brought in contact with the screen protector  10 . 
     The movable member  200  may further has a stopper  250  and a recession  260  and the film housing  100  may further have a stopper groove  160 . 
     The stopper  250  restricts movement of the movable member  200  when the movable member  200  is moved to be coupled to the film housing  100 . The stopper  250  is formed opposite to the terminal seat  230 . For example, the stopper  250  may protrude from the film-pressing side  240 , opposite to the terminal seat  230 . That is, the stopper  250  is disposed close to the upper end of the movable member  200 . The shape of the stopper  250  is not specifically limited, and for example, the cross-section of the stopper  250  may be a right triangle. When the cross-section of the stopper  250  is a right triangle, the vertical side of the right triangle may face the terminal seat  230 . The stopper  250  can limit the movement distance of the movable member  250  by corresponding to the upper end of the bottom  110  of the film housing  100  when the movable member  200  is moved to be coupled to the film housing  100 . 
     The recession  260  may be formed concavely perpendicular to the movement direction of the movable member  200 . For example, the recession  260  may be formed concavely toward the outer side of the cover portion  210  from the film-pressing side  240 . The recession  260  is smaller in area than the film-pressing side  240 . A screen cleaner etc. may be stored in the recession  260 . 
     The stopper groove  160  is fitted on the stopper  250 . To this end, the stopper groove  160  may have a shape corresponding to the cross-section of the stopper  250 . For example, when the stopper  250  has a right triangular cross-section, the stopper groove  160  may also have a right triangular cross-section. The stopper groove  160  may be formed on the inner side of the bottom  110  of the film housing  100 , between the pair of guide walls  140  and close to the upper end of the film housing  100 . 
     On the other hand, the case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention may further include a dirt remover  330  and the film housing  100  may further have a terminal holder  170 . 
     The dirt remover  300  is provided to remove dirt on the screen of the mobile terminal  30  before the screen protector film  12  of the screen protector  10  kept in the film housing  100  is attached. The dirt remover  300  is combined with the film housing  100 , close to the film seat  130  and close to the terminal seat  230  of the movable member  200  coupled to the film housing  100 . For example, the dirt remover  300  may be a roller. In this case, both ends of the roller may be connected to the sides  120  of the film housing  100  through shafts so that the roller can rotate. An adhesive sheet  310  may be wound on the roller to remove dirt from a screen. When the mobile terminal  30  is put inside the terminal seat  230  of the movable member  200  and then the movable member  200  is moved by pushing the mobile terminal  300 , the roller can be rotated by the movement of the mobile terminal  30  and the adhesive sheet  310  can remove dirt on the screen of the mobile terminal  30 . 
     The terminal holder  170  is a portion that supports the mobile terminal  30  when the upper end or the lower end of the mobile terminal  30  is placed inside the terminal seat  230 . The terminal holder  170  may be formed on the inner side of the bottom  110  of the film housing  100  to face the dirt remover  300 . For example, the terminal holder  170  may have an L-shaped cross-section. In this case, the upper end of the terminal holder  170  may be the same as or smaller in height than the dirt remover  300 . 
     A process of attaching a screen protector film to the screen of a mobile terminal using the case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention is described hereafter with reference to  FIGS. 3 and 4 .  FIG. 3  is a perspective view showing a case when a mobile terminal is placed in a terminal seat to illustrate of a process of using the case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention and  FIG. 4  is a perspective view showing a case when a screen protector film is separated from a separation film by moving a movable member to illustrate of a process of using the case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention. 
     In order to attach a film to the screen of a mobile terminal, first, the movable member  200  is coupled to the film housing  100  with the screen protector  10  in the film seat  130  of the film housing  100 , in which the screen protector film  12  of the screen protector  10  is positioned to face the inner side of the cover portion  210  of the movable member  200 , the upper end of the screen protector film  12  faces the lower end of the film housing  100 , and the lower end of the screen protector film  12  faces the upper end of the film housing  100 . The upper end of the screen protector film  12  is connected to the terminal seat  230  of the movable member  200  by the tag  20 . 
     In this state, the upper end of the mobile terminal  30  is moved inside the terminal seat  230  of the movable member  200 , as shown in  FIG. 3 . The upper end of the mobile terminal  30  is kept inside the curved portion  231  of the terminal seat  230 , and the pushing protrusion  232  and the pair of guides  233  of the terminal seat  230  is positioned around the upper end of the mobile terminal  30 . Further, the terminal holder  170  supports the mobile terminal  30  and the screen of the mobile terminal  30  faces the dirt remover  300 . 
     Next, the movable member  200  is moved to be separated from the film housing  100  by pushing the mobile terminal  30  toward the upper end of the film housing  100 . While the mobile terminal  30  and the movable member  200  are moved, the dirt such as dust on the screen of the mobile terminal  30  is removed by the dirt remover  300  and the screen protector film  12  is separated from the separation film  11  and attached to the surface of the screen of the mobile terminal  30 , as shown in  FIG. 4 . 
     That is, as the mobile terminal  30  is moved, the roller of the dirt remover  300  rotates, and the adhesive sheet  310  wound on the roller removes the dirt such as dust on the screen of the mobile terminal  30 . Further, as the movable member  200  is moved and the terminal seat  230  is gradually moved away from the upper end of the screen protector film  12 , the upper end of the screen protector film  12  is pulled by the tag  20  attached to the terminal seat  230 , whereby the upper end of the screen protector film  12  is separated from the separation film  11 . The upper end of the screen protector film  12  separated from the separation film  11  is bent and turned over such that the adhesive side of the screen protector film  12  faces the mobile terminal  30 . Further, as the mobile terminal  30  keeps moving, the adhesive side of the screen protector film  12  is attached to the surface of the screen of the mobile terminal  30 , whereby the screen protector film  12  is attached to the screen of the mobile terminal  30 . In this process, while the movable member  200  is moved, the film-pressing side  240  of the movable member  200  presses the screen protector  10  kept in the film seat  130 . 
     When the movable member  200  reaches the upper end of the film housing  100 , the entire surface of the screen protector film  12  is separated from the separation film  11  and attached to the entire screen of the mobile terminal  30 . 
     The case for attaching a screen protector film for a mobile terminal according to an embodiment of the present invention has the following advantages. 
     First, the screen protector film  12  is attached to the screen of the mobile terminal  30  only by placing the upper end or the lower end of the mobile terminal  30  inside the terminal seat  230  and then moving the movable member  200  by pushing the mobile terminal  30  toward the upper end of the film housing  100 , so it is possible to very easily and quickly attach the screen protector film  12  for protecting the screen of the mobile terminal  30 . Further, it is possible to attach the screen protector film  12  to the screen of the mobile terminal  30  without a failure in the process of attaching the screen protector film  12  to the screen of the mobile terminal  30 . 
     Second, since the dirt such as dust on the screen of the mobile terminal  30  is removed by the dirt remover  300  before the screen protector film  12  is attached to the screen of the mobile terminal  30 , it is possible to attach the screen protector film in a clean state without dirt between the surface of the screen of the mobile terminal  30  and the screen protector film  12  attached to the screen. 
     Third, since while the movable member  200  is moved, the entire screen protector  10  in the film seat  130  of the film housing  100  is pressed by the film-pressing side  240  in the process of attaching the screen protector film  12  to the screen of the mobile terminal  30  by moving the movable member  200 , it is possible to prevent the screen protector  10  from coming off or separating inside the film seat  130 . Accordingly, a failure in the process of attaching the screen, protector film  12  due to coming-off or separation of the entire screen protector  10  is prevented.
