2. Description of the Related Art
Generally, a mobile phone means all phones that may communicate with a general phone subscriber or a different mobile communication phone subscriber through a base station within a wireless zone while a user moves optionally within a mobile communication area like a car phone. Such a mobile phone is called by the name of a portable phone, a mobile phone, a cordless cellular phone, a cordless portable phone, a pocket phone, etc.
Such a mobile phone is a phone communication terminal that can be easily used while a user carries. Recently, modern people possess the mobile phone as an essential item. The cellular phone is equipped with many additional functions, including digital multimedia broadcasting (DMB), a navigation system, a camera, and a multi media player for playing an MPEG audio layer-3 and a digital moving picture, and performs more functions as a digital device using an application program called application (APP).
In recent years, additional functions are being added to smart phones coming to market, for example the function of surfing a wireless internet through a so-called 4-generation (4G) data communication network and wireless fidelity (WiFi). The design and shape of the smart phone has become better, and the overall size of the smart phone becomes smaller to allow it to be put into a pocket of clothes with minimum weight, so that the weight of the smart phone is gradually reduced. Most of smart phones that are available in Korea today are a bar type in which a front having a screen is formed as a touch screen. The touch screen on the front is made of tempered glass.
The tempered glass is advantageous in that it is resistant to scratch or impacts acting on the front. However, the tempered glass is very vulnerable to impacts acting on the side. Thereby, when a smart phone having a display panel made of the tempered glass falls to the ground because of carelessness during its use, a front panel protecting the display panel or the display panel itself is broken due to impacts against the ground.
Hence, a user is more susceptible to scratching, cracking, or damaging a cellular phone that is relatively expensive and is good in appearance. Moreover, the cellular phone has a growing tendency to be utilized as an accessory that suits a user's taste, by using the appearance of the cellular phone. In order to satisfy a user's demand, cellular-phone cases of various kinds and materials are being developed and coming to market to prevent the damage to the cellular phone and to provide a good appearance.
A mobile phone case is typically classified into a pouch type, a wallet type and a housing/case type. The pouch type is intended to hold and store the mobile phone in a holding space made of leather or cloth. The wallet type is configured to form a space holding a mobile phone therein by cutting leather and to open and close a cover. The housing/case type is made of a synthetic resin material such as plastic or silicone, thus allowing the mobile phone to be fitted into and held in a holding space defined therein.
However, the pouch type is problematic in that the entire cellular phone is completely put into the holding space defined in the pouch, so that the cellular phone should be taken out from the pouch when a user desires to use the cellular phone, thus causing inconvenience. The wallet type is problematic in that the cover of the wallet should be opened or spread to use the cellular phone, thus causing inconvenience when a user desires to make a phone call. Meanwhile, the housing/case type is advantageous in that it is easy to confirm contents displayed on the touch screen disposed on the front of the bar type cellular phone, and in addition, it is easy to use a touch key on the touch screen. However, the housing/case type is problematic in that the material of the housing/case is mainly synthetic resin such as plastic, so that it has an unpleasant texture or feel.
Further, modern people generally carry the cellular phone as well as at least one or more cards, for example, a transportation card for paying a public transport fare, a credit card used to buy goods on credit, and a discount card for getting a discount when purchasing goods. Even though these cards are used in everyday life as frequently as the cellular phone, it is common to store the cards in a separate wallet.
Recently, a cellular-phone case having a card holding structure is being developed to simultaneously carry both the cellular phone and the card, thus making it convenient to use the cellular phone and the card.

Accordingly, these terms should be defined based on the entire contents of the specification.
Further, the following embodiment does not limit the scope of the present invention but is merely illustrative. It is possible to implement various embodiments through the technical spirit of this invention.
FIG. 1 is a perspective view showing a cellular-phone case having a retractable card holding structure according to the present invention, FIG. 2 is an exploded perspective view showing the cellular-phone case having the retractable card holding structure according to the present invention, FIG. 3 is a bottom perspective view showing a disassembled state of the cellular-phone case having the retractable card holding structure according to the present invention, FIG. 4 is a front view showing the cellular-phone case having the retractable card holding structure according to the present invention, and FIG. 5 is a rear view showing the cellular-phone case having the retractable card holding structure according to the present invention.
As shown in the drawings, the cellular-phone case 10 having the retractable card holding structure according to the present invention (hereinafter referred to as the cellular-phone case for convenience sake) is the cellular-phone case that holds a card in such a way as that it is put into or taken out from the case. Such a cellular-phone case 10 includes a case body 20 and a card holding means 30.
The case body 20 is open at one side thereof to allow a user to touch a display screen of a cellular phone (not shown) fastened to the case body 20, and is made of a synthetic resin material having elasticity. The case body 20 has a seating space 21 to allow the cellular phone to be fitted and seated therein. An outlet 221 is provided at a predetermined position on a back portion 22 of the case body 20 in such a way as to communicate with the seating space 21.
Here, a rectangular receiving hole 222 is formed in an inner surface of the back portion 22 and communicates with the outlet 221 to allow a support panel of the card holding means 30 that will be described below to be put into and taken out from the case body 20. A pair of guide grooves 223 each having a triangular cross-section is formed longitudinally in the receiving hole 222. Rail grooves 224 are further formed on both sides of the receiving hole 222 to guide both ends of the support panel 31.
Further, a plurality of through holes 225 is formed in the back portion 22 of the case body 20 to take a picture. Annular heat dissipation protrusions 226 are further formed on the inner surface of the case body 20 in such a way as to surround the through holes 225. An elongated spacer protrusion 227 is further formed in the receiving hole 222 to prevent the cellular phone seated in the case body 20 from rubbing against the moving support panel 31.
In other words, the heat dissipation protrusions 226 dissipate heat from the interior of the case, thus preventing heat from escaping to the outside via the through holes 225. The spacer protrusion 227 prevents the support panel 31 from rubbing against the cellular phone while the support panel 31 is moved in and out. The support panel 31 is formed in the shape of an elongated bar using synthetic resin. Here, the support panel 31 is movably engaged with the rail grooves 224 that are provided on both sides of the receiving hole 222, so the support panel 31 can be moved along the rail grooves 224.
In this respect, the heat dissipation protrusions 226 are formed at regular intervals in such a way that heat dissipation protrusions having relatively larger diameters surround heat dissipation protrusions having smaller diameters.
The card holding means 30 includes the support panel 31 which is fitted into the outlet 221 and on which the card 100 is disposed, and an actuating body 32 which is provided on a side of the support panel 31 and is disposed to be caught by the outlet 221. The support panel 31 and the actuating body 32 are integrated into a single structure and are made of a synthetic resin.
Here, a pair of guide protrusions 311 is provided on an upper surface of the support panel 31 in such a way as to be fitted into the guide grooves 223 and thus guided. An elongated receiving hole 312 is further formed to receive embossed letters (letters, such as a card number or an expiration date, protruded by pressing) that protrude from a surface of the card 100, in addition to separating the card 100 from the support panel 31.
Preferably, a rectangular recess is further formed in the upper surface of the support panel 31 to allow a lower portion of the card to be fitted therein.
Further, the guide grooves 223 are not connected to the outlet 221 to prevent the guide protrusions 311 of the support panel 31 from being separated from the guide grooves 223 and thereby prevent the support panel 31 from being removed from the outlet 221.
Here, an actuating recess 321 is formed in the upper surface of the actuating body 32, while a locking protrusion 322 is formed on the lower surface of the actuating body 32. The locking protrusion 322 is locked to a locking hole 231 that is formed in the inner surface of an outer wall 23 provided on a side of the case body 20.
The use of the cellular-phone case having the retractable card holding structure configured as described above will be described. First, a user inserts his or her nail or finger into the actuating recess 321 to take the card 100 out from the cellular-phone case and then pulls the actuating body 32 out. At this time, the locking protrusion 322 is removed from the locking hole 231, so that the support panel 31 is moved along the rail grooves 224 to be taken out.
Subsequently, he or she puts his or her finger into the lower portion of the receiving hole 312 of the support panel 31 to raise the card 100 disposed on the upper surface of the support panel 31. Thereafter, the card 100 is gripped by the other hand and then is used. After the card 100 has been used, the card 100 is placed on the upper surface of the support panel 31 in such a way as to be locked to the guide protrusion 311. Next, the support panel 31 is moved into the case such that the locking protrusion 322 engages with the locking hole 231.
