Protective cover for mobile communication device {SAFEGUARD COVER FOR MOBILE PHONE}

The present invention relates to a protective cover for a mobile communication device, and more particularly, to a protective cover that is in close contact with the surface of a mobile communication device such as a cellular phone, PDA, and the like, as well as adding various functions.

Conventionally, the protective cover of the mobile communication device is a housing made mainly of leather or synthetic resin having a grip force, and the mobile communication device is inserted therein to prevent scratching of the display part or the keypad part of the mobile communication device and prevents the mobile communication from external impact. It meant protecting the device as well as providing additional functionality as an accessory.

However, in a reality where the function and shape of a mobile communication device (commonly called a cellular phone or a mobile phone) are rapidly being changed, the present invention is used in a flip-up type or a folder type cellular phone. The display part has been developed to a sliding phone, which is slidingly coupled with the keypad part, and the protective cover made of a material such as a conventional housing type and thick synthetic resin has a dull design and usability, so it is realistically avoided by teenagers and twenties. In addition, there is a structural problem in properly protecting a cellular phone in which a display unit having a screen display function and a keypad unit for inputting numbers and letters are simultaneously provided on one surface of a sliding phone or a cellular phone that are currently in vogue.

It can be seen that a number of such a mobile phone protective cover of the housing type is disclosed, Utility Model No. 279631 does not adequately protect the shape of the mobile communication device that is currently produced in various forms due to the basic characteristics of the housing shape, design and accessories Registered Utility Model No. 261783, which emphasized the function of, gives a frustrating gaze for use in summer due to the thick material production. In addition, such a housing-type cover can also give a bad effect that the user is caught in opening and closing the folder due to the thick material.

Therefore, the main purpose is to protect the surface of the cellular phone, except that the protective cover acts as an external shock absorber. For this purpose, the protective cover is designed to be simple and focused on the protective function. Registered Utility Model No. 264878, which is made of resin, is disclosed, but this also protects the display and keypad of the clamshell cell phone by enclosing them in a housing form, so that opening and closing of the folder may be jammed. There is a disadvantage in that it does not provide other functions beyond the degree of wearing a visual function and there is also a problem that it is difficult to be compatible with various types of mobile communication devices.

The present invention has been made to improve such a problem, while providing a protective cover of a thin layer away from the mobile communication device protective cover structure of the conventional housing structure, while performing an appropriate protection function for the display unit and keypad unit and also for the display unit It aims to provide various functions.

Another object of the present invention is to have a combined configuration so that two covers made of different materials can be used separately from each other according to the use in order to effectively protect the surface of modern mobile communication devices manufactured in various sizes and shapes. .

Another object of the present invention is to contain iron material in the cover to enhance the binding force of the mobile communication device on a metal holder or hands free.

As can be seen from Figure 1, the protective cover of the present invention is composed of a first cover 10 for protecting the display unit 1 of the mobile communication device and a second cover 20 for protecting the keypad (2) And the junction part 30 is located between them, and joins both.

The first cover 10 and the second cover 20 may be manufactured in a structure in which the first cover 10 and the second cover 20 are coupled to each other by a single extension line 30, but as shown in FIG. Therefore, the first cover 10 may be manufactured in a structure such that the first cover 10 is accommodated on the second cover 20. According to this structure, the second cover 20 includes a plurality of joints 30 to be described below. It may be possible to separate more than two.

The first and second covers 10 and 20 are basically coating members which are made of a thin layer of 0.04 to 2 mm, and are directly used by being closely coated on the surface of the mobile communication device.

With such a close coating method, the protective cover according to the present invention not only prevents scratches on the surface of the mobile communication device, but also takes care of the waterproof function of the surface portion vulnerable to moisture, and has the advantage of maintaining the touch feeling of the keypad.

The first and second covers 10 and 20 may be integrally formed to cover a non-folding mobile communication device in which a display unit 1 and a keypad unit 20 are integrally formed on a front surface thereof. In order to be appropriately used in mobile communication devices of various shapes such as a mold, it is preferable that both covers 10 and 20 are separated and used and can be re-bonded as necessary. Let's explain.

The recess 31 may be manufactured by a piercing process according to a punching pressing die after the first cover 10 and the second cover 20 are integrally manufactured by a hot pressing process. At the center lower end of the recess portion 31, there is formed a cutting groove 32 having a sharp shape of an upper and lower strait, that is, an inverted triangle. The lower portion of the incision groove 32 may vary according to the thickness of the cover, but the first cover 10 and the second cover 20 before the separation of the connection part 33 having a thickness of 0.02 to 0.5 mm exist. Support the connection state of. Accordingly, the user may connect the first cover 10 and the second cover 20 to the joint portion 30 according to various mobile communication devices, such as a front integrated type (non-flip to non-foldable type), flip type, folding type, sliding type and the like. After separating each of the two through the incision groove 33 in a manner that can be used in various ways as a protective cover of the display unit 1 and the keypad unit 2, even the battery unit 3.

According to such a configuration, the user may initially separate the first cover 10 and the second cover 20 so that both of them can be separated as described above, but cannot be combined again. In order to improve this, Figure 3 shows another embodiment of the bonding structure of the first cover and the second cover according to the present invention.

Referring to FIG. 3, it can be seen that the junction part 30 ′ is configured in two forms. Referring to the structure (A) of the first junction portion 30 ', it is a structure that is sawtooth coupled to each other by the teeth formed in the end of the first cover 10 and the second cover 20.

In other words, the upper end of the first cover 10 is provided with an inverted 'V' shaped upward bent groove, and the end portion which is attached to the lower cover is formed with a 'V' shaped downward protrusion, and the second cover configured to engage with the second cover ( 20) the end portion of the V-shaped downward bent groove and the end portion that is in contact with the inverted 'V' shaped upward protrusion is provided with the end structure of each of the form of 'N', so that both are coupled to each other. At this time, the junction part 30 'has a slightly distorted' N 'shape and is not separated by the force in the lateral direction. Therefore, when it is attached to the surface of the mobile communication device, the force to be pushed unless the cover is lifted due to the adhesion to the surface. It can be used so that it is not separated by. In addition, when the user wants to separate each of them, it is possible to separate both covers 10 and 20 while slightly lifting the first cover 10 upward in FIG. 3.

In addition, referring to the structure B of the second joining portion 30 ′, an uneven groove is formed at the end of the first cover 10 so that the reverse uneven groove is provided at the end so as to be engaged with each other. When the second cover 20 is unevenly coupled and is not separated by the lateral force similarly to the structure A and the above, when separation is desired, the second cover 20 can be used separately.

2 or 3 may be formed to extend in a single linear shape connecting the first cover 10 and the second cover 20, but it is intermittent in a dotted form as necessary. It is possible to form and may have a curved shape rather than a straight line, it may be composed of two or more joining portions according to the connection form of the first cover 10 and the second cover 20.

The first cover 10 is a transparent cover for protecting the display unit 1, and can be basically composed of the same material as the second cover 20 to be described below, but pays attention to the characteristics provided for screen protection. It can be made of a variety of materials.
