1 is a perspective view showing a configuration in which the first and second bodies are coupled in a portable electronic device protection case according to the present invention.

As can be seen from Figure 1, the protective case 10 according to the present invention is a portable electronic device, for example, bar type (flat or flat) provided with a display unit consisting of LCD or LED on the surface (defined as 'front') It is configured to surround the side and bottom surfaces (ie, opposite sides of the display unit) of PMPs, MP3 players, PDAs, mobile phones, and netbooks having a slightly curved shape, for example, the protective case according to the present invention ( The shape of 10) is similar to the shape of a protective case widely sold in the US for the iPhone (I-Phone) of Apple.

The protective case 10 according to the present invention includes a first main body 100 configured to surround a part of a side (upper side) of the portable electronic device, and a portable electronic device below the portion wrapped in the first main body 100. The second body 200 surrounding the side portion (lower side) and the rear surface (that is, the opposite surface of the front portion in which the display unit is formed) is configured to be integrally coupled.

Figure 2 is a longitudinal cross-sectional view showing a configuration in which the first and second body is coupled in the portable electronic device protection case according to the present invention, Figure 3 is a first and second body is coupled in the portable electronic device protection case according to the present invention It is a partial cutaway perspective view which shows the structure.

The first main body 100 according to the present invention is stacked on the second main body 200. Specifically, the upper side protection part 120 surrounding the upper part of the rounded or straightened side of the portable electronic device 120. ) And a first coupling part 130 formed to be coupled to the second body 200 at the lower end of the upper side protection part 120, and additionally, the upper side protection part 110. And a front circumferential protection part 110 that is bent inward from the top of the circumference to surround the front of the portable electronic device (ie, the surface on which the display part is formed).

The first main body 100 is based on an elastic material, which is the first main body 100 must be elastically bent and protected when the portable electronic device is inserted into the protective case 10 according to the present invention. This is because portable electronic devices can be accommodated in the case.

That is, the first main body 100 according to the present invention is made of a material having sufficient elasticity, for example, urethane, so that the bending and elasticity of the portable electronic device can be appropriately maintained without being damaged when the portable electronic device is mounted or removed. It is to provide a function to have it.

In addition, when assuming that the inner part of the first main body 100 is bisected in the extending longitudinal direction (longitudinal direction) and the outer part of the opposite side and the outer part of the opposite side occur, the inner part has a predetermined length toward the lower side, That is, it extends from a lower side point or a lower side of the portable electronic device to a slightly upper point (the point just above the rear surface), which is called the first coupling unit 130.

That is, the first coupling portion 130 is formed to extend downward to have a step from the inner portion relative to the lower center of the upper side protection portion 120.

When the first coupling portion 130 is formed to be curved to surround the portable electronic device configured to have a curvature on the side of the protective case according to the present invention, the first coupling portion 130 is extended in a downward direction while being bent in accordance with the corresponding curvature. .

The outer portion of the first coupling portion 130 is in contact with the second coupling portion 230 of the second body 200 to be described later and the inner portion is in contact with the portable electronic device.

The second main body 200 according to the present invention is located below the first main body 100, and specifically, the lower side protection part 210, the rear protection part 220, and the second coupling part 230. It consists of.

Unlike the first main body 100, the second main body 200 is made of an inelastic material or a hard material (such as polycarbonate to ABS). The second main body 200 provides a bendability to mount a portable electronic device to a protective case. Unlike the (100) it can be said to be made to focus more on the impact protection role of the portable electronic device.

The lower side protector 210 serves to wrap the lower point of the side of the portable electronic device, which is particularly aware that the boundary between the side and the back is ambiguous in the portable electronic device having the curvature of the side of the portable electronic device. Wrap the lower part where it meets the back of the middle.

The back protection unit 220 serves to wrap the back of the portable electronic device (ie, the opposite surface of the display unit).

The second coupling part 230 bisects the second body 200 in the extending longitudinal direction (ie, the longitudinal direction), and assumes that an inner part that contacts the portable electronic device and an outer part of the opposite side are generated. Refers to a site where the site extends a certain length toward the upper side.

That is, the second coupling portion 230 refers to a portion extending upwardly with a step from the outer portion with respect to the upper center point of the lower side protection portion 210.

The second coupling portion 230 is in contact with the first coupling portion 130, specifically, the outer surface of the first coupling portion 130 and the inner surface of the second coupling portion 230, the first Surface formed at the end of the coupling portion 130 and one side of the lower side protection portion 210 of the second body 200, surface formed at the end of the second coupling portion 230 and the upper side of the first body 100 One surface of the side protection part 120 is in surface contact, such that the first and second main bodies 100 and 200 make a total of three surface contacts.

In particular, the reason why the second coupling part 230 is located on the outer side of the first coupling part 130 is to properly accommodate the elastic force of the first body 100 in the first coupling part 130. When the flow force is transmitted to the first coupling unit 130 by the elastic flow of the first body 100, the first coupling unit 130 may absorb the first coupling unit 130 better than when it is outside, and the second coupling unit ( This is to allow the 230 to absorb the remaining impact amount of the first coupling portion 130 from the outside thereof.

Bonding and bonding of the first and second coupling parts 130 and 230 are performed by a double injection molding method.

Double injection molding refers to the technology of producing products in one mold, which are mainly composed of two kinds of colors or molding materials. Dual injection molding is generally molded through a dual injection molding machine and also imparts the characteristics that the double injection mold has to be complicated and high in precision in order to operate in the molding machine.

That is, the first and second coupling parts 130 and 230 according to the present invention use a double injection process because the first and second bodies 100 and 200 are made of different synthetic resin materials, and the first and second main bodies are formed by double injection molding. When the protective case according to the present invention is completed through a process in which the 100 and 200 are combined in a mold, the coupling parts (combination line) of the first and second coupling parts 130 and 230 are not exposed, as if the first and second main bodies 100 and 200 are integrated. Combination can be made to the characteristics such as durability of the bond.

That is, in the protective case according to the present invention, the first body 100 made of an elastic material and the second body 200 made of a hard material for impact prevention are integrally formed by a double injection method so as to conveniently fit portable electronic devices. Although coupled, the coupling sites, that is, the first and second coupling parts 130 and 230 are formed to have a step, so that the contact area can be increased to boast excellent coupling force, and the elastic force of the first body 100 and the second body ( It provides a property to make full use of the shock absorption of the 200).

4 is a conceptual diagram illustrating a modified embodiment of the first coupling portion and the second coupling portion according to the present invention.

FIG. 4 illustrates a configuration in which the first and second coupling parts 130 and 230 are bent in two stages. Specifically, the first coupling part 130 is formed at an inner side (portable electronic device mounting direction) outside the end of the first body 100. Primary side extension 131 extending downward (nearly horizontal) and the primary downward extension 132 extending downward from the inner side of the primary side extension 131, the primary downward extension The secondary lateral extension 133 extending from the side 132 to the inner side near the horizontal and the secondary downward extension 134 extending downward from the inner end of the secondary lateral extension 133 again; And a third lateral extension 135 extending almost horizontally from the second downward extension 134 to the inner surface of the first body 100.

Correspondingly, the second coupling part 230 also corresponds to the above-described detailed configuration of the first coupling part 130, so that the first side extension part 231, the first lower extension part 232, and the second side extension part ( 233, the 2nd downward extension part 234, and the 3rd lateral extension part 235 are provided in surface contact with each corresponding detailed structure.

That is, the first and second coupling parts 130 and 230 according to FIG. 4 have a stepped step (step) formed in two stages, and more precisely double injection in the state in which the detailed surfaces of the first and second coupling parts 130 and 230 are combined more densely. By doing so integrally and serves to ensure that the bonding force with the second body 200 is sufficiently ensured by the elasticity of the first body 100.

5 is a conceptual view illustrating a state in which a buffer unit is configured in a first coupling unit according to the present invention.

As can be seen from Figure 5, the shock absorbing portion 140 in the outer inner portion of the first coupling portion 130 in contact with the second coupling portion 230 in the first coupling portion 130 of the first body 100. And constitutes a through-hole 240 formed in the transverse direction in the direction of the outer surface of the second body 200 in the buffer 140.

The buffer unit 140 is made of a material having a stronger elasticity than that of the first body 100, and performs a function of dispersing and absorbing the elasticity transmitted to the first body 100 or itself, and remains unabsorbed. The impact serves to distribute to the outside through the through hole 240.

That is, in order to prevent the flow force generated in the first main body 100 directly transmitted to the second main body 200 to increase the fatigue degree on the second main body 200, the buffer unit 140 and the through-hole 240. It provides a function to ensure durability by distributing the flow force appropriately through forming a.

As described so far, the configuration and operation of the portable electronic device protective case combining two main bodies according to the present invention have been described in the above description and the drawings, but this is merely an example and the idea of the present invention is described in the above description and the drawings. Without being limited, various changes and modifications are possible without departing from the technical spirit of the present invention.
