Description

BACKGROUND

1. Field of the Art
The invention relates generally to protective and decorative casings for handheld or mobile devices such as a cellular phones, mobile computing devices, and portable digital media players. More specifically, the present invention relates to an expandable covers for mobile phones.
2. Description of the Prior Art
Mobile/cellular phones have become quite ubiquitous. Additionally, mobile phone manufacturers and sellers frequently create and sell phones with new designs, new shapes, and new sizes. Moreover, cellular service providers now allow and encourage mobile phone users to “upgrade” their respective phones by getting a brand new phone at least biannually. Each new phone purchase requires the user to purchase new phone accessories, such as car chargers, wall chargers, screen covers, and protective cases. All of these types of mobile phone accessories, especially protective phone cases, are often unique to particular phone designs.
Other mobile electronic devices such as tablet computers, certain laptop computers, digital medial players, and the like are also often used with protective covers. Covers for these other types of mobile must also be replaced each time a use purchases such a device having a new size or shape.
Thus, a need exists for a protective cover for a portable/mobile electronic device such as a cellular phone, mobile computing device, or a portable digital media player, where the cover need not be replaced each time a user purchases a new device. More specifically, a need exist for an expandable phone casing of which may be used with a plurality of phone sizes and shapes.
