Hereinafter, a case 1 for a portable terminal according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4 attached hereto.

The case 1 for a portable terminal according to an embodiment of the present invention protects the portable terminal 100 from damage that may occur during use and when the user holds the portable terminal by hand, To a case for a portable terminal capable of providing a grip feeling.

The portable terminal case 1 includes a body portion 10 and a corner portion 20.

The portable terminal 100 (see FIG. 4), to which the portable terminal case 1 is coupled, has a flat hexahedron shape whose length in the vertical direction is longer than the width in the horizontal direction, A right side, an upper side, a lower side and a rear side. The portable terminal is not limited to a name such as a mobile phone, a smart phone, a tablet terminal, and the like, and is interpreted to include all the information communication terminals that the user can hold by hand.

The body 10 is in the form of a flat plate which can be brought into contact with the rear surface of the portable terminal while being coupled to the portable terminal 100.

The body 10 is manufactured to have a size that occupies most of the area of the rear surface of the portable terminal. According to the embodiment, the body portion may be smaller than the area of the rear surface of the portable terminal.

In the case of the present embodiment, the body portion 10 is formed integrally with the corner support portion 22. Means that the body portion 10 and the corner support portion 22 are integrally connected to each other. It can be mass-produced by means of mold injection.

A through hole 12 for a camera lens 106 provided in the portable terminal is formed in the body 10.

On the other hand, the integrally formed body portion 10 and the corner support portion 22 may be collectively referred to as a main body member. The body portion 10 and the corner support portion 22 are made of polycarbonate (PC) material which can realize high rigidity and high transparency in this embodiment. On the other hand, the polycarbonate may have a color.

In other embodiments, the body portion and the corner support portion may be integrally formed, but may be made of other materials other than polycarbonate and having a high rigidity.

However, in the case of the present embodiment, the body portion and the corner support portion are made of transparent polycarbonate, so that even when the body portion and the corner supporting portion are coupled to the portable terminal, the user can feel the color of the portable terminal intact.

The corner portions 20 are provided at four corners of the body 10.

Each of the corner portions 20 is composed of a corner support portion 22 and a corner buffer portion 24. The corner support portions 22 extend from the respective corners of the body portion 10 and extend in a shape that can be engaged with corresponding corners of the portable terminal. That is, if the shape of the corresponding corner of the portable terminal is a shape processed by a curved surface rather than an angular corner, the shape of the corner supporting portion 22 is also changed to the shape of the corner of the portable terminal, Shape.

Usually, the case for the portable terminal comes out as a special case to fit only a concrete model of the end of the portable terminal according to each manufacturer, so the specific shape and size are designed to exactly fit the shape of the portable terminal to be applied. Accordingly, the shape of the corner support portion is also formed so as to have a shape exactly matching the corner of the portable terminal to be used.

In the present embodiment, the corner buffering portion is manufactured by the insert injection forming method, and the corner buffering portion 24 is formed so that the corner supporting portion 22 and the corner buffering portion 24 can be firmly engaged with each other. A plurality of grooves 222 are formed in the outer surface 224.

In the grooves 222 formed in the outer side surface 224 of the corner support portion 22, a part of the corner buffer portion can be inserted. The corner cushion having fluidity is filled in the groove 222 of the corner support in the manufacturing process and then hardened.

Due to the groove 222 and the portion of the corner cushion inserted in the groove, the corner support 22 and the corner cushion 24 have the same bonding force as that formed by almost all the members.

The corner buffering portions 24 are formed to be engaged with the respective corner supporting portions 22. The corner buffering portion 24 is made of a material having a higher elastic modulus than the corner supporting portion 22 and is capable of absorbing an external impact.

The corner cushion 24 surrounds the outer surface 224 of the corner support 22 and a portion of the body 10. In the present embodiment, there is no corner buffer on the inner surface 226. [ 3, the height of the corner buffering portion 24 in the up-and-down direction can protect the upper surface liquid level of the portable terminal to be coupled with the height of the camera lens 106 And the height of the protruding portion is sufficient.

That is, when the portable terminal is placed on a flat surface in a state where the case 1 is coupled to the portable terminal, the corner buffering part 24 protrudes upward from the liquid crystal upper surface of the portable terminal, Respectively.

When the portable terminal is unintentionally dropped in the state where the case 1 is coupled, all the cases are often dropped to the corner portion. In this case, the corner buffering portion 24 of the material having a high elastic modulus absorbs the impact, It is possible to prevent falsification.

In the case of this embodiment, the corner buffer 24 is made of a thermoplastic polyurethane (TPU). The TPU is excellent in workability and durability as well as elasticity, and is suitable as the material of the corner buffering portion 24. [

However, in another embodiment, the elastic force may be made of another material higher than the body portion or the corner support portion, such as silicon or rubber.

In this specification, a corner refers to four corners in the case of a portable terminal. Particularly, the corner of the portable terminal to which the corner portion 20 is coupled means the periphery of the corner where the lower side meets the two sides. That is, the corner portion 20 is coupled to the four corners of the lower side of the portable terminal. However, the height of the corner portion 20 is greater than the thickness of the portable terminal, so that it is protruded above the front surface of the portable terminal in a coupled state. As a result, the front surface including the liquid crystal of the portable terminal is protected.

In the portable terminal case 1 according to the present embodiment, except for the corner portion 20, there is no portion facing the left and right side surfaces and the upper and lower side surfaces of the portable terminal to be coupled. However, in order to prevent the risk that the rim of the through-hole 12 may be damaged due to the presence of the through-hole 12, the body 10 may be slightly extended from the upper surface of the portable terminal It is possible.

Hereinafter, the operation and effects of the case 1 for a mobile terminal having the above-described configuration will be described.

When the four corners 20 are sequentially coupled to the corresponding corners of the portable terminal while the body 10 is slightly elastically deformed, the operation of attaching the four corners 20 to the portable terminal 100 Is completed.

4, even when the portable terminal such as a smart phone is connected to the case 1, it is possible to use only the four corners of the portable terminal 100 And the corner portion 20 is coupled, and the side surface 102 and the lower surface 104 are directly exposed. Except for the side portions and the upper side surface portions of the opposite side which are not indicated, except for the portion where the corner portion 20 is wrapped. However, depending on the embodiment, the upper portion of the body may be partially extended to enclose a part of the upper surface.

Therefore, it is possible to protect the portable terminal from damage even if the user drops the portable terminal, and it is possible to feel a grip feeling like holding the portable terminal without the case while the both sides of the portable terminal are held by hand .

Here, the grip feeling is a feeling that the user feels when the user holds the portable terminal in his hand. The user may prefer the grip feeling depending on his or her preference. However, since the user hates the increased volume due to the case and uses the portable terminal without a case, A case for a mobile terminal can be a good choice. In addition, although a very thin case is used for a user who does not like the bulky feeling, there is a problem that the case covers the portable terminal as a whole and also it is difficult to prevent breakage from impact in case of falling.

In the case of this embodiment, since the corner buffering portion is firmly coupled to the corner support portion, not only the durability is excellent but also the corner portion of the portable terminal can be sufficiently protected.

In addition, since the body portion and the corner supporting portion are made of polycarbonate, they are robust, durable, durable, and have high transparency. have.

In addition, in the present embodiment, the body portion 10 and the corner support portion 22 are formed of a single piece of transparent polycarbonate material, and a corner buffer portion 24 of a transparent TPU material is formed on the outer surface of the corner support portion 22, Are tightly coupled, there is also a feature that volume is minimized. However, it may be implemented in various colors depending on the embodiment.

In addition, when the portable terminal falls down, it often falls down to the corner portion. Since the corner buffering portion is formed of the TPU, the portable terminal is advantageously absorbed by the impact to prevent damage to the portable terminal.

A method of manufacturing a case for a portable terminal according to another aspect of the present invention is disclosed.

The method for manufacturing a case for a mobile terminal of the present invention is a method for manufacturing a case for a mobile terminal having the above-described structure.

The manufacturing method includes a step of providing a main body member and a step of forming a corner buffer.

The first step is to include a main body member, wherein the main body member includes an integrally formed body portion 10 and a corner support 20. In the case of this embodiment, the main body member is made of a polycarbonate material using a mold. However, in other embodiments, the main body member can be made of various materials and by various manufacturing methods.

Next, coupling of the corner cushion to the corner support of the main body member is performed.

The corner cushioning portion is formed on the corner support portion by an insert injection molding method. Each corner supporting portion is placed as an insert in the inside of the previously prepared mold and the material for forming the corner buffering portion is filled in the inside of the mold.

In the case of this embodiment, the material for forming the corner buffer is thermoplastic polyurethane (TPU). The TPU material heated to have fluidity is injected into the mold, separated from the mold after a predetermined time, and completely cooled to completion.

At this time, a plurality of grooves 22 are provided on the outer side surface of the corner support portion 22 so that the grooves 22 are filled in the TPU injection.

According to the case manufacturing method of the portable terminal of this embodiment, by using the insert injection method, the corner buffer can be firmly coupled to the corner support portion. The corner buffer portion and the corner support portion are rigid, as they are formed almost integrally. In addition, there is an advantage that the production process is simplified and productivity is high.

Further, since grooves are formed on the outer side surface of the corner support portion, the grooves can be filled into the grooves when the insert is injected.
