Hereinafter, specific embodiments of the present invention and its operations will be described with reference to the accompanying drawings. Embodiments described herein are described to help understanding of the present invention, whereby the technical spirit of the present invention is not limited.

Unless otherwise stated throughout the specification, the same reference numerals refer to the same components, and the words used in the singular are intended to include the plural unless otherwise indicated.

As is apparent from the following description, the present invention can be used as a protective case of various portable communication terminals such as mobile phones and PDAs as well as smart phones. However, in the present specification, for convenience of description, it is assumed that the present invention is applied to a protective case of a smartphone.

As used herein, the term 'hard' means greater hardness and less ductility than 'soft'.

In addition, the display portion of the portable communication terminal is a portion that needs to be exposed to the outside by displaying characters, images, etc., the rear portion of the portable communication terminal is the opposite portion of the display portion, the side portion of the portable communication terminal is the display portion And a part connecting the rear part.

In addition, the side surface portion of the portable communication terminal protective case body is a portion corresponding to the side surface of the portable communication terminal, the rear portion of the portable communication terminal protective case body is a portion corresponding to the rear portion of the portable communication terminal.

1 and 2 is an exploded perspective view showing the configuration of a portable communication terminal protective case 10a according to an embodiment of the present invention, Figure 3 is combined with each configuration of the portable communication terminal protective case 10a of FIG. 4 is a perspective view illustrating a state, and FIG. 4 is a cross-sectional view taken along line AA of FIG. 3.

1 to 4 together, the portable communication terminal protective case 10a according to an embodiment of the present invention is soft formed by injection molding or the like to correspond to the shape of the portable communication terminal (for example, smartphone). It consists of a protective case body 100 and a hard protective case frame member 200 that is bound to the outer edge portion of the protective case body 100.

The protective case body 100 may be configured using, for example, a soft material such as soft silicone, a rubber raw material such as soft urethane, a soft polyurethane, and / or a soft ethylene vinyl acetate. Specifically, the protective case body 100 may be manufactured by, for example, a method of molding the above-described soft materials into a shape corresponding to the appearance of the portable communication terminal by using a thermoforming machine. For example, the above-described soft materials may have a strength of 5 to 40 measured by a standard strength measuring system (C-Type), and may be a material having good flexibility and flexibility.

The portable communication terminal protective case 10a, which is an embodiment of the present invention, forms the protective case body 100 as one of the above-described soft materials, thereby closely closing the outer circumferential surface of the portable communication terminal (not shown) with a unique softness. It can be wrapped, thereby blocking the possibility of dust or foreign matter penetrates between the gap between the portable communication terminal and the protective case (10a).

In addition, the portable communication terminal protective case 10a, which is an embodiment of the present invention, is formed by forming the protective case body 100 from one of the soft materials described above, and thus scratches (scratches) during mounting / removing work with the portable communication terminal. May not occur at all.

According to a preferred embodiment, the protective case body 100 is formed with one or more fitting grooves 110 of the structure coupled to the fitting protrusion 210 of the rigid protective case rim member 200. Specifically, the portable communication terminal protective case 10a according to an embodiment of the present invention is the protective case body 100 and the protective case border member by a method of fastening the fitting protrusions 210 and the fitting grooves 110 to each other. The 200 can be bound to each other. By the fitting protrusion 210 and the fitting groove 110, as well as attaching the hard protective case rim member 200 to the protective case body 100, it is easy to detach. As a result, the hard protective case rim member 200 in a variety of colors, by combining the protective case body 100 by replacing, it is possible to produce a variety of personality of the user.

The hard protective case rim member 200 is integrally wrapped with the side portion and the rear portion of the protective case body, so that a portion of the rear portion is exposed, thereby exhibiting the effect of the hard protective case rim member 200 to achieve At the same time, it is possible to increase the surface resistance by the exposed soft rear part and thus have an effect of not slipping even when placed on an inclined surface or the like. In addition, the hard protective case rim member 200 is bound to the boundary portion 105 between the rear center portion 103 and the side end portion 107 of the soft protective case body, thereby exposing the soft rear center portion 103. In order to increase the surface resistance, and to be able to detachably detach or install the portable communication terminal accommodated by the side end portion 107 of the soft protective case body, the effect of the hard protective case rim member 200 to achieve Can be represented.

According to a preferred embodiment, the protective case main body 100 is provided with the

function button protrusions

120 and 130 for function button corresponding to the function button, the function button of the portable communication terminal is inserted is formed as a function button operation portion do. Specifically, the protective case body 100 has a hold button protrusion 120 into which a hold button (not shown) of a portable communication terminal is inserted, and a protrusion 130 for a volume button into which a volume button (not shown) of a portable communication terminal is inserted. ) May be formed. Hold button protrusion 120 and the volume button protrusion 130 is a structure that is elastically pressed and restored. Accordingly, the user pushes the hold button protrusion 120, the volume button protrusion 130, and the like, even when the protective case 10a is mounted on the outer circumferential surface of the portable communication terminal, to thereby protect the outside of the protective case 10a. Each hold button (not shown) and the volume button (not shown) can be manipulated at.
