Description

Case for bar type mobile apparatus and method of making the case and mobie apparatus}

The present invention is a hard material that can be assembled or disassembled by wrapping or disassembling the side of the bar-type mobile device (mobile devices other than the slide or folder type is called a bar shape). A bar type portable device case and a method for assembling with a bar type portable device.

In today's society, portable electronic devices such as mobile phones, PDAs, and DMBs are becoming essential belongings. Mobile phones, which are representative examples of portable electronic devices, play video, music, digital cameras, DMB, navigation, Internet, as well as unique call functions. Various additional functions are added, and the design and shape thereof are becoming more and more beautiful. Recently, the development of bar-type products (smartphones such as Galaxy phones, iPhones, etc.) in which the front surface of the mobile phone is formed with a touch screen is increasing.

Accordingly, users are more sensitive to scratches, scratches, and breakages that can occur on their expensive and beautiful mobile phones, and they are also becoming more inclined to use them as a kind of accessory by making the appearance of the mobile phones more beautiful.

In order to meet the demands of the present, portable electronics cases of various kinds and materials that have a beautiful appearance while preventing damage to various portable electronic devices have been developed and sold. There are two main types.

One is a case formed of a soft material, which is made of a material such as silicone, urethane, elastomer, etc., which can be covered in the side and the back of the portable electronic device, and is bonded using its own elasticity. No pressure is applied and no scratch is generated. However, the soft case is not only very weak in protecting portable electronic devices from external shocks, but also has a problem in that the soft case is unnecessarily frequently peeled off unnecessarily because of the weak bonding force.

The other is a hard case made of a synthetic resin material (plastic material), and the hard case has a structure that protects the back and the circumferential surface of the portable electronic device integrally so that the portable electronic device is inserted into the case of the container type. Often used. In this case, the bonding force is relatively strong, so that it is stably mounted on the portable electronic device, but damage such as scratches may occur remarkably in the process of inserting the portable electronic device into the case of the case. In addition, many scratches were generated on the back and the circumferential surface of the portable electronic device due to the material characteristics of the hard case even after being used.

Conventional bumper cases for overcoming the disadvantages of such hard cases are known in the patent literature. The bumper case means a case that covers the entire side of the mobile device.

The bumper case of the portable electronic device 500 of the patent document separates the base frame 100 and the upper and lower frames 200 and 300, respectively, as shown in FIG. By reducing the frictional force that can be applied to prevent scratch damage of the portable electronic device (500).

However, the bumper case assembled or disassembled in the form of the vertical sliding side of the related art also has a sliding friction, and thus scratches may occur on the side of the portable electronic device 500 and its periphery (edge portion).

Meanwhile, in the electronic device for a mobile device, in particular, a smartphone, a microphone 510 for input and a speaker 530 for output are disposed on the lower side. Therefore, the microphone hole 310 and the speaker hole 330 for the microphone 510 and the speaker 530 are formed in the conventional bumper case.

However, the microphone hole 310 and the speaker hole 330 are drilled downwards, and the sound enters and exits outwards, and thus, the microphone hole 310 and the speaker hole 330 are distributed downward. Media sound quality amplification is less effective.

On the other hand, the power button is formed on the upper side of the smart phone, the power button hole 210 for the power button is also formed through the upper side of the case.

However, when the power button protrudes from the power button hole 210, the power button may be left undesirably in a state where the power is increased.

To prevent this, if the thickness of the bumper case is thickened so that the power button does not protrude, it is very inconvenient because it is difficult to press the power button.

In addition, the left side of the smartphone has a volume control button, such as a ring tone, the volume control button hole 230 for the volume control button is formed in the bumper case.

By the way, the bumper case of hard material has a certain thickness, the volume control button through the volume control button hole 230 is hardly protruded, so it is not easy to press.

In addition, in the case of an integrated bumper case made of soft material, the case itself needs to be pressed to operate the volume control button or the power button. In this case, the contact feeling is reduced (that is, it is recognized that the touch is activated even when the thickness of the case is pressed. Dropped) it is difficult for the user to recognize whether the buttons were pressed.

In the conventional bumper case, a headphone minijack hole 250 for the headphone minijack 550 of the mobile device 500 is formed through.

However, it is difficult to insert a professional headphone jack having a relatively large diameter in the headphone minijack hole 250, and the seat is formed by cutting it into a 'c' shape. Base frame 100 is required.

As shown in FIGS. 1 to 4, the bar-shaped portable device case 1 according to the preferred embodiment of the present invention includes a strip-shaped frame 10 having both ends surrounding the sides of the bar-shaped portable device 500, and a strip. It includes a connecting portion 30 for connecting one end (a) and the other end (b) of the shape frame 10.

The strip-shaped frame 10 includes a first frame 11, a second frame 13, and a third frame 15 surrounding the left and right sides 501 and 503 and the lower side 505 of the bar-shaped portable device 500. In addition, the fourth frame 17 surrounding a part of the upper side 507 of the bar-type portable device 500 is integrally configured. Of course, even if the fourth frame 17 is formed on the left and right side 501, 503 or the lower side 505 other than the upper side 507, it will be apparent to those skilled in the art that there is no difference in function.

One end (a) of the belt-shaped frame 10 corresponds to the free end of the fourth frame 17, and the other end (b) of the belt-shaped frame 10 corresponds to the free end of the first frame (11). That is, since the strip-shaped frame 10 is a quadrangular shape as a whole, but is not a closed type but an open belt-shaped frame cut in the middle, there is no need for push or sliding assembly.

The strip-shaped frame 10 has a cross-sectional shape of a letter 'C', and has a web frame 10a in contact with the side surfaces 501, 503, 505, and 507 of the mobile device 500, and a side of the mobile device 500. 501, 503, 505, 507 consists of a flange frame 10b that wraps around the edge to prevent disengagement during assembly.

The strip-shaped frame 10 is injection-molded with a hard material, for example, a plastic material, which is elastically deformable, and is convenient when assembling or detaching slightly apart.

Therefore, by implementing the strip-shaped frame 10 of a hard material that can be elastically deformed, the mobile device is stably protected from impact such as dropping, thereby ensuring a role as a protective case.

At the same time, by implementing the structure wrapped around the side 501, 503, 505, 507 of the mobile device 500, unlike the conventional push or sliding assembly to eliminate the friction caused by the assembly caused by the mobile device 500 There is a significant effect of preventing scratches at the source.

A hinge pin 31a is formed at one end A of the connection part 30, and a locking pin 33a is formed at the other end B of the connection part 30.

On the other hand, a hinge groove 31b to which the hinge pin 31a is pivotally coupled is formed at one end a of the fourth frame 17, and a locking pin (b) is formed at the other end b of the first frame 11. A locking groove 33b on which 33a) is engaged is formed.

Accordingly, the connecting portion 30 functions as a holder for assembling (locking) or disassembling (unlocking) the belt-shaped frame 10.

In particular, as shown in FIG. 3, the locking groove 33b includes a guide groove 33b ′ and a locking jaw groove 33b ″ formed at a lower end of the guide groove 33b ′.

Guide groove (33b ') is formed from the top to the bottom is composed of inclined guide groove (33b') is inclined (θ) to be located inward than the bottom.

That is, the inclined guide groove 33b 'has a wider shape than the lower side thereof, or has a straight line shape with the same inclination in the first upper limit region.

Due to the configuration of the inclined guide groove 33b ', it is possible to form an easy-to-assemble or disassembled angle by simply pushing the locking pin 33a against the inclined surface, thereby significantly reducing wear of the locking groove 33b and improving wear resistance. Let's do it.

In addition, the locking jaw groove (33b ″) is in the 'c' shape when the locking pin (33a) is securely prevented from being randomly separated by the pulling force on both ends.

Hinge groove (31b) is formed on the other end (b) of the fourth frame (17), it is preferable to be formed of a vertical guide groove and a c-shaped locking jaw groove from the bottom upwards opposite to the locking groove (33b).

The engaging groove 33b and the hinge groove 31b have a groove shape in which front and rear surfaces and upper surfaces are open.

It is preferable that the locking pins 33a be implemented.

The hinge pin 31a does not receive a large load during operation, so a pin with a small diameter may be used. However, the locking pin 33a receives a large load during assembly or disassembly. It is preferable that 30c connects the other ends of the front and back plates 30a and 30b.

Therefore, a cashier 31 in which the mobile phone minijack 550 is cashier is formed at the center of the connection unit 30.

At this time, the front and rear plates 30a and 30b are preferably formed with embossed portions 35a and 35b which are convex outwardly.

Since the embossing parts 35a and 35b play a role of widening the size of the cashier 31, a professional headphone jack having a size larger than that of the minijack 550 may be used as well as the existing headphone minijack 550.

In addition, since the embossed portions 35a and 35b slightly protrude outwardly with respect to the edges, the embossed portions 35a and 35b can be picked up with a finger when releasing the latches, which is particularly convenient for removal.

In addition, the embossed portions 35a and 35b also serve as reinforcing ribs, and can prevent the front and rear plates 30a and 30b from bending when they are caught by a straight line.

The connection part 30 may be made of a plastic material, such as the belt-shaped frame 10, but it is preferable to increase the durability by using a metal material in terms of continuing assembly and disassembly.

On the other hand, it is preferable that the inner surface of the third frame 15 is formed with a sound quality improvement groove 50 is opened in the front and upper surfaces.

That is, as shown in FIG. 3, the sound quality improvement groove 50 is formed of a bottom 51, both side walls 53, 55, and a rear wall 57, and when the mobile device 500 is assembled, only the front is opened. To achieve the state.
