Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to mobile device protection devices and more particularly, to a mobile device protection case, which is partially elastically deformable for easy insertion of a mobile device in the case body thereof without scratching. 
     2. Description of the Related Art 
     Conventional mobile device protection cases are generally composed of two mating case members. After insertion of a mobile device in between the two mating case members, the two mating case members are forced into engagement with each other to secure the inserted mobile device firmly in position. However, the two mating case members can easily be forced apart upon an accidental impact. Screws or other fastening members can be installed to lock the two mating case members together. However, the use of screws or other fastening members to lock the two mating case members together greatly complicate the use of the mobile device protection case. 
     There is known another prior art design of mobile device protection case, which comprises a hard back panel, and two guard flanges located at two opposite lateral sides of the hard back panel. In application, impart a pressure to the mobile device against the guard flanges to expand the guard flanges bilaterally outwards for allowing the mobile device to be closely attached to the surface of the hard back panel. After the mobile device is set in between the two guard flanges and closely attached to the surface of the hard back panel, the mobile device is held on the hard back panel by the two guard flanges. However, when forcing the mobile device in between the two guard flanges, the mobile device can be scratched by the two guard flanges, and the two guard flanges can easily be forced to break. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a mobile device protection case, which is partially elastically deformable for easy insertion of a mobile device in the case body thereof without scratching. 
     To achieve this and other objects of the present invention, a mobile device protection case comprises a case body and an adapter member. The case body comprises a bottom wall, a first upright peripheral wall upwardly extended from the bottom wall around the border thereof and exhibiting a U-shaped profile, a first retaining flange transversely extended from the topmost edge of the first upright peripheral wall and suspending above the bottom wall, and an accommodation chamber surrounded by the bottom wall and the first upright peripheral wall. The adapter member is made from a flexible material, comprising an abutment wall abutted against one end of the bottom wall of the case body in a flush manner, a second upright peripheral wall upwardly extended from the abutment wall along the border area thereof and abutted against the first upright peripheral wall in a flush manner, a second retaining flange transversely inwardly extended from the topmost edge of the second upright peripheral wall and abutted against the first retaining flange in a flush manner, and a mating chamber surrounded by the butment wall and the second upright peripheral wall and disposed in communication with the accommodation chamber. In application, curve the abutment wall of the adapter member downward to open one end of the accommodation chamber, and then insert the mobile device into the accommodation chamber to let the first upright peripheral wall cover the peripheral edge of the mobile device and the first retaining flange be attached to the border area of the top surface of the mobile device. Thereafter, release the pressure from the abutment wall of the adapter member, enabling the adapter member to return to its former shape elastically. At this time, the second upright peripheral wall covers the peripheral edge of the mobile device and the second retaining flange is stopped at the border area of the top surface of the mobile device, and thus, the mobile device is firmly held in the accommodation chamber of the case body and the mating chamber of the adapter member and well protected by the case body and the adapter member.
