Description

{PROTECTIVE CASE FOR MOBILE DEVICES}

The present invention relates to a protective case for a mobile terminal, and more particularly, to a protective case for a mobile terminal, in which an inner member formed of a hard material having a predetermined rigidity is coated with an outer member made of a soft silicone material, To a protective case for a mobile terminal, which is configured to protect a user's body while protecting the user's body with an aesthetic effect.

Generally, a mobile terminal is a personal terminal configured to be able to communicate with another user while online, access online, watch video or broadcast, and the like. The mobile terminal corresponds to a mobile phone, a PDA, or a tablet PC.

In addition to basic communication functions, these mobile terminals are now being introduced as high-priced products due to the addition of a large number of additional functions such as a media player, a digital camera, and a digital storage device and a large-sized touch screen. It is desirable to stably protect the appearance of the terminal from surface scratches or external impacts for clean use.

Accordingly, various protective cases for protecting the appearance of the mobile terminal have been manufactured and sold. Such a protective case can be divided into a so-called hard case made of a hard material (e.g., plastic or metal) and a so-called soft case made of a soft material (e.g., synthetic resin or silicone).

Since the hard material used for the hard case has a predetermined rigidity, the material can have sufficient shape retention even if it is made to have a small thickness. Therefore, the hard case can be manufactured to be thin enough not to damage the slim shape of the terminal, thereby providing aesthetic satisfaction to the user. However, since the hard material used in the hard case does not have sufficient shock absorbability, the case itself and the terminals mounted in the case can not be faithfully protected from external impacts. For example, if a terminal with a plastic hard case is dropped on the floor, the hard plastic case may easily break, and the appearance or internal parts of the terminal mounted inside the terminal may be damaged. Furthermore, since materials such as plastic or aluminum used in the hard case generally have a smooth surface, the possibility of sliding in the user's hand is relatively high, and the possibility that the terminal and the case are damaged by an external impact is further increased.

On the other hand, soft material such as synthetic resin or silicone used for the soft case has a certain degree of shock absorbing ability, so that the terminal can be stably protected against external impact as compared with the hard case. Further, the material such as silicone is less likely to slip off the terminal from the hand because the surface of the material does not slide smoothly compared to plastic materials used in the hard case. However, since the soft material used for the soft case is not high in the rigidity of the material itself, if the case is formed with a thin thickness, the shape can not be maintained and the case must be formed to have a large thickness. This thick thickness damages the slim appearance of the terminal and deteriorates the aesthetics. Therefore, there is a problem that the latest trend that requires a slim appearance design is not satisfied.

As described above, conventional conventional protection cases are insufficient to meet the expectation of the consumer who intends to prevent damage to the terminal while not degrading the slim appearance of the terminal.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a new protection case that can solve the above-described problems of the related art and can reduce the possibility of damaging a terminal while maintaining aesthetic feel without damaging the slim appearance of the terminal.

A typical configuration of the present invention for achieving the above-mentioned object is as follows.

The protective case according to the present invention is configured to enclose a rear surface, a side surface, and a front surface of a mobile terminal, and includes an inner member formed of a hard material made of plastic or metal to form a basic skeleton of the protective case, And an outer member configured to surround the inner member in the form of a thin film. Wherein the outer member is configured to surround the inner member without a separate adhesive layer.

According to one embodiment of the present invention, the inner member may be formed of POLYCARBONATE.

The outer member of the present invention may have a through hole, and a part of the inner member may be exposed to the outside through the through hole. At this time, the inner member and the outer member are formed in different colors so that a new aesthetic effect can be added through the combination of colors of the inner member and the outer member.

The outer member and the inner member of the present invention are preferably formed to have a small thickness. For example, the outer member may be formed to a thickness of 0.5 mm or less, and the inner member may be formed to a thickness of 1 mm or less.

In addition, the protective case for a mobile terminal according to the present invention may further include other additional configurations as long as the technical idea of the present invention is not adversely affected.

The protective case according to the present invention can provide the following effects.

Since the inner member is formed of a hard material having a predetermined stiffness such as polycarbonate to form the basic skeleton of the protective case, the protective case can be formed in a thin thickness. Further, since the outer member formed of a soft silicon material is coated in the form of a thin film on the inner member thus formed, a protective case having a silicon outer surface can be formed with only a thin silicon layer. That is, it is possible to form a protective case having a silicon outer surface even in a very slim form compared with conventional silicon protective cases.

Further, the present invention can provide a good grip to the users due to the soft touch of the silicon material forming the outer surface of the protective case.

Further, since the soft silicone material has a surface characteristic that does not slip more easily than a hard case material such as plastic or aluminum, the use of the protective case of the present invention reduces the possibility of dropping the terminal from the user, Can be reduced.

In addition, the non-slip properties of the silicone member can further facilitate temporary storage of the terminal. For example, when the protective case of the present invention is used, the terminal can be stably maintained without slipping even when the terminal is placed on the dashboard of the vehicle in operation.

Since the present invention is made up of two different members (an inner member and an outer member), the aesthetics of the case can be further improved through the combination of two different members. For example, in the protective case of the present invention, a through hole is formed in the outer member so that the inner member is partially exposed, so that various designs can be formed through the combination of colors of the inner member and the outer member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

In order to clearly illustrate the present invention, a detailed description of parts that are not related to the present invention will be omitted, and the same components will be denoted by the same reference numerals throughout the specification. In addition, since the shape and size of each component shown in the drawings are arbitrarily shown for convenience of explanation, the present invention is not necessarily limited to the illustrated shape and size. That is, the specific shapes, structures, and characteristics described in the specification may be changed and embodied from one embodiment to another without departing from the spirit and scope of the present invention. It is to be understood that changes may be made without departing from the scope. Therefore, the following detailed description is not intended to be construed in a limiting sense, and the scope of the present invention should be construed as encompassing the scope of the claims of the utility model registration claims and all ranges equivalent thereto. For example, although the following description specifically describes a protection case for a smartphone terminal (Apple's iPhone 6 mobile phone), the present invention should not be limited to such a terminal.

1 and 2 show a protective case 1 according to an embodiment of the present invention. More specifically, FIG. 1 shows a perspective view of a protective case 1 according to the present invention, and FIG. 2 shows a plan view of the protective case 1 according to the present invention. 1 and 2, the protective case 1 according to the present invention is generally composed of a back surface portion 10 and a side surface portion 20 extending substantially vertically from the back surface portion. The back surface portion 10 and the side surface portion 20 In the inner space formed by the mobile phone. The upper portion of the side portion 20 is configured to extend inward in a direction substantially parallel to the back surface portion to grip a part (rim portion) of the front surface of the mobile phone. That is, the protective case 1 protects the rear surface, the side surface, and a part of the front surface of the cellular phone.

The protective case 1 according to one embodiment of the present invention is constructed by forming an inner member 100 formed of a hard material such as polycarbonate as shown in FIG. 3 with an outer member 200 formed of a soft silicon material, . Here, the inner member 100 forms the basic skeleton of the protective case 1, and the outer member 200 forms the outer surface of the protective case 1.

4 and 5 show the specific shape of the inner member 100. As shown in Fig. 5, the inner member 100 includes a back portion 110 and a side portion 120 extending substantially vertically from the back portion. The inner member 100 includes a back side 110 and a side portion 120, Is accommodated. The upper portion of the side portion 120 is configured to extend inward in a direction substantially parallel to the back surface portion so as to cover a part (frame portion) of the front surface of the mobile phone.

Generally, various functions are formed on the outer surface of the mobile phone. For example, a photographing device such as a digital camera may be formed on the rear surface of the mobile phone, and a function switch such as a power button, a mode change switch for changing the mode of the mobile phone (sound mode / vibration mode) . These functions formed on the outer surface of the mobile phone are not properly functioned if they are obscured by the inner member 100. Accordingly, the present invention has an opening for exposing functional portions formed on the outer surface of the cellular phone to the back surface portion 110 and the side surface portion 120 of the inner member 100.

Specifically, an opening 130 for an image pickup apparatus is formed on the back surface 110 of the inner member 100 to expose a photographing device of the mobile phone. A power button opening 140 for exposing the power button of the mobile phone is formed on one side surface 120 of the inner member 100 and a mode change switch An opening 150 for the mode change switch for exposing the volume control button and an opening 160 for the volume control button for exposing the volume control button of the cellular phone are formed.

Meanwhile, an earphone connection part and a charge cable connection part may be provided on the upper or lower part of the mobile phone. Therefore, it is preferable to form the grooves (the earphone access groove 170 and the charging cable access groove 180) so that the earphone and the charging cable can be easily accessed to the corresponding portion of the inner member 100.

In the present embodiment, the inner member 100 is made of a hard material having a predetermined rigidity such as a polycarbonate material so that the inner member 100 can maintain its shape even if it is thin. However, a metal material such as aluminum used in a normal hard case can also be used as the material of the inner member 100 of the present invention. However, the polycarbonate material used in the present embodiment is more advantageous in terms of cost and weight than the metal material. Since the polycarbonate material has a relatively high elasticity and impact absorbing power as compared with a metal material such as aluminum, it can be advantageous in terms of ease of attachment and impact prevention performance of a terminal, It can be more advantageous from the point of view. The inner member 100 made of polycarbonate can be molded into a desired shape through a process such as press molding or plastic molding.

A hard material such as polycarbonate has a certain degree of rigidity and is advantageous in that the shape can be maintained even if it is formed into a thin thickness. That is, it has an advantage that it can be formed to have a thin overall thickness. However, since such a material does not have a high impact absorbing capability, it can not stably protect the terminal mounted therein from an external impact or the like. Further, since a hard material such as polycarbonate usually has a smooth surface, there is a concern that it is easy to slide in a user's hand.

In order to solve this problem, the present invention is configured to surround the outer surface of the inner member 100 formed of a hard material such as polycarbonate with the outer member 200 of a thin film formed of a soft silicon material. 1 and 2 show a protective case 1 according to the present invention in which an outer surface of an inner member 100 is covered with a silicon outer member 200. FIG.

As described above, in order for the function unit formed on the outer surface of the mobile phone to operate smoothly, they must be exposed to the outside. To this end, the protective case 1 of the present invention prevents the silicon outer member 200 from covering the openings formed in the inner member 100, such as the imaging device opening 130 and the mode change switch opening 150, So that the opening portion 30 for the photographing apparatus and the opening portion 50 for the mode change switch can be formed in the protective case 1.

However, since the silicone material forming the outer member 200 has strong ductility, the configurations (the power button and the volume control button of the present embodiment) formed in the button shape of the above-described functional portion of the cellular phone are covered by the silicone material It is not a big problem to operate outside the silicon outer member. Accordingly, the portions where these functional portions are located may be configured to be covered with the silicon outer member 200. If a large number of through holes are formed in the protective case 1, there is a high possibility that external foreign matter or moisture flows through the through holes. Therefore, in the present invention, the portion where the button- (200). 1 and 2, the opening 140 for the power button and the opening 160 for the volume control button of the inner member 100 are covered with the silicon outer member 200, And a volume adjusting section 60 are formed. The earphone access groove 170 and the filler cable access groove 180 formed in the inner member 100 for facilitating the accessibility of the earphone and the charge cable may be formed in a groove shape (For example, the charging cable access groove 70 and the charging cable access groove 80) so as not to obstruct the access of the earphone and the charging cable.

As described above, the protective case 1 of the present invention is formed of two members (an inner member and an outer member) formed of different materials. When a plurality of members formed of different materials are combined to form a single structure as in the present invention, a separate adhesive layer for joining a plurality of members together is generally required. However, the formation of such a separate adhesive layer increases manufacturing cost and manufacturing time, and increases the size of the protective case, thereby making the appearance of the case blunt.

In contrast, the present invention is characterized in that no separate adhesive layer or adhesive is disposed between the outer member 200 and the inner member 100 when the outer member 200 is coated on the outer surface of the inner member 100. For example, the protective case 1 of the present invention is formed by forming an inner member 100 through a process such as press molding or plastic molding, and then forming an outer portion of the thin film on the outside of the inner member 100 by injection molding, Is formed by covering the member (200). That is, the outer member 200 is formed by placing a molded inner member 100 on a mold, injecting a liquid silicone material between the inner member 100 and the mold, cooling the same, And may be formed to surround the outer surface of the inner member 100 in the form of a thin film.

According to such a configuration, since the inner member 100 formed of a hard material such as polycarbonate can form a basic shape of the protective case even with a small thickness, the entire thickness of the protective case is made thin and a sophisticated and slim shape Protective case manufacturing becomes possible. In addition, the silicone outer member 200 coated on the outside of the inner member 100 can provide the user with a stable feeling of grip with a soft feeling, and the non-slip property of the silicone material reduces the risk of the mobile phone slipping off the hand . In addition, due to the non-slip characteristics of such a silicone material, temporary storage of terminals such as mobile phones can be facilitated. For example, when the protective case of the present invention is used, the terminal can be stably maintained without slipping even when the terminal is placed on the dashboard of the vehicle in operation.

A through hole 210 may be formed in the outer member 200 forming the outer surface of the protective case 1 to add a design element to the outer surface of the protective case. When the through hole is formed in the outer member 200, the inner member 100 located inside the outer member 200 is exposed to the outside. Thus, a combination of the inner member 100 and the outer member 200 can be used to add an aesthetic element. For example, if the through hole 210 is repeatedly formed in the outer member 200 as shown in FIGS. 1 and 2, the inner member 100 is exposed through the through hole 210, (A specific pattern, a logo, a trademark, or the like) through the color combination of the inner member 100 and the inner member 100, and design elements can be added to the outside of the protective case. A planar space 220 in which a through hole is not formed in a part of the outer surface of the outer member 200 may be secured to imprint the model name or the like.

FIG. 6 shows a state in which a mobile phone is mounted on a protective case 1 according to an embodiment of the present invention. According to the present invention, even if the thickness of the protective case 1 is made very thin (for example, even if the inner member 100 is formed to be 1 mm or less and the outer member 200 is formed to 0.5 mm or less) It is possible to stably grasp and support. For example, in an embodiment of the present invention shown in the drawings, the inner member 100 of the protective case 1 is formed to be 0.9 mm, and the outer member 200 is formed to have a very thin thickness of about 0.3 mm. Therefore, even when the protective case 1 of the present invention is mounted on the cellular phone, the overall thickness can be substantially increased and the slim design of the cellular phone can be maintained. 7, even if the protective case 1 according to the embodiment of the present invention described above is mounted on the cellular phone, the total thickness t2 (approximately 8.7 mm) is smaller than the thickness t1 (approximately 6.9 mm ) Compared with that of the conventional method.

While the present invention has been particularly shown and described with reference to 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. It can be understood that It is to be understood, therefore, that the embodiments described above are illustrative in all aspects and not restrictive.
