An attachment to a mobile device, allowing a user to grasp and use the device. The attachment may include three concentric, interlocking rings. An outer ring adhered to a backing plate may be affixed to a surface of a device, such as a rear surface of a cell phone, smart phone, personal digital assistant, calculator, MP3 player, iPod, iPad, tablet computer or other mobile device. An inner ring attaches to a middle ring via a hinge mount. The grasping device may resemble a ring for a finger of a user, by which a user grasps the attachment and thus the mobile device. The inner and outer rings may be connected and interlocked by a mating middle ring. The middle ring allows the inner ring to rotate relative to the outer ring, allowing the user to conveniently position or orient the mobile device as desired. Other shapes may be used. |
