Title: Size-adaptive mobile device cover

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a mobile device cover, and more particularly to a protection cover adaptive to mobile devices of different sizes. 
     2. Description of the Related Art 
     A variety of peripheral products have been constantly introduced to the market as a result of widespread mobile devices, such as tablet personal computers (PC), smart phones, and the like. A conventional protection cover commonly seen in the market primarily serves to receive a mobile device therein to protect the mobile device against collision, scratch, wear, and the like when the mobile device is carried along or is operated. Such protection cover is indeed necessary, especially when the mobile device is costly. 
     The conventional protection cover takes the form of a book, is standable, and has a first cover board, a second cover board, and a mounting frame. The mounting frame has a receiving bag mounted thereon and having a receiving chamber. The receiving bag has at least one insertion opening formed through one side of the receiving bag and a display opening formed through a top surface of the receiving bag. The first cover board is connected between the mounting frame and the second cover board. Each of the first cover board and the second cover board has multiple folding lines such that the first cover board and the second cover board can be folded for the protection cover to stand up. 
     Although the foregoing protection cover can receive a mobile device inside the protection cover and protect a mobile device against collision, scratch and wear, the size of the protection cover must fully comply with that of the mobile device. However, most mobile devices in the market are of different sizes. Hence, protection covers of different sizes need to be manufactured to meet such demand. Price hike of the protection covers is also reflected on the incompatibility concern. Besides, even though the receiving chamber of the receiving bag is sufficient to accommodate mobile devices of different sizes, smaller mobile devices may be scratched or collided, or slip out of the receiving bag since the mobile devices are not fully bounded by the protecting cover. 
     SUMMARY OF THE INVENTION 
     An objective of the present invention is to provide a size-adaptive mobile device cover capable of holding mobile devices of various sizes and protecting mobile devices against collision, scratch and wear. 
     To achieve the foregoing objective, the size-adaptive mobile device cover has a protection cover and multiple angle holders. 
     The protection cover has two cover boards. One of the cover boards has an inner surface and a first movable fixing portion. The first movable fixing portion is located on the inner surface. 
     Each angle holder has a second movable fixing portion, and is selectively and detachably mounted on the first movable fixing portion. Locations of the angle holders determine where the first movable fixing portion is located on the cover board on which the first movable fixing portion is formed. 
     When a mobile device is to be put inside the protection cover of the size-adaptive mobile device cover, two angle holders respectively hold any two diagonal corners of the mobile device and the two angle holders are mounted on the inner side of one of the cover boards. As the angle holders are selectively and detachably mounted on the inner side of the corresponding cover board, the size-adaptive mobile device cover is applicable to mobile devices of various sizes. 
     Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
