Description

PROTECTION COVEROF SLIDE TYPE CELLULARPHONE

TECHNICAL FIELD The present invention relates to a protection cover of a slide type cellular phone, which is fixed to a main body of the cellular phone and an outer side of a display portion, protects the cellular phone from external impact by injection molding to have elasticity, and enables use of a functional button and a charging port without any interference. More particularly, the present invention relates to a protection cover of a slide type cellular phone, in which the cellular phone is protected from external impact by the protection cover fixed to the main body and the display portion, increases esthetic appearance, maintains mechanical strength by injection molding for semipermanent use.

BACKGROUND ART Generally, a protection cover of a cellular phone is designed by leather, synthetic resin, or artificial leather having pinch strength to form a predetermined shape. The protection cover protects the c ellular phone provided inside the protection cover from damage such as scratch generated by contact friction between a surface of the cellular phone and other objects. Also, the protection cover prevents the cellular phone from being damaged by external impact and enhances esthetic appearance of the cellular phone if it functions as an accessory. Meanwhile, the cellular phone includes a main body having button portion and is divided into a folder t ype, a flip type, and a s lide type depending on opening and closure of a display portion fixed to the main body by a hinge unit to open and close. As shown in FIG. 1, a protection cover of a general folder type cellular phone includes a lower cover 3 fixed to a main body 2 having a button portion 1 and provided with a transparent inner side, and an upper cover 6 fixed to a cover 5 having a display portion 5 and provided with a transparent inner side. In this case, the lower cover 3 and the upper cover 6 may be provided in a single body. Alternatively, after they are separately provided, they are fixed to each other by a clamp means (not shown). The protection cover has several problems. It is likely that the transparent inner sides may be contaminated by sweat from hand of a user during long use of the cellular phone. If dust or the like is stuck on the cover, it is difficult for the user to recognize the display portion 4 and the button portion 1. Particularly, this may cause inconvenience to a user having poor eyesight. Further, if the cellular phone is fallen by an oversight in a state that the protection cover is fixed to the cellular phone, the cellular phone may be damaged because of weak cushion force of the lower and upper covers 3 and 6. Therefore, a problem occurs in that corresponding parts of the cellular phone should be repaired or the cellular phone should be exchanged with new one. Moreover, if the protection cover is used for a long time, elasticity of a member fixed to the inner side of the protection cover is reduced so that the protection cover may be loosened on the cellular phone. In this case, since the function of the cover is lost to reduce use span, the cover should be exchanged with a new one after the lapse of a predetermined time. Meanwhile, since the cellular phone is slid to the corresponding parts to close or open in a state that the display portion or the main body is tightly fixed to the protection cover, the folder type or flip type protection c over fails to be fixed to the slide type cellular phone. At this time, if the protection cover is fixed to the display portion or the main body of the slide type cellular phone using glue, it should forcibly be detached from the cellular phone to exchange batteries with new ones or repair inner parts. In this case, a problem occurs in that the protection cover cannot be used again after exchange or repair.
