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.
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
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.
