Patent ID: 8326381

Claim:
A mobile device, comprising: a base portion that includes a guide base; a slider portion that includes a sliding plate, wherein the slider portion is slidably engaged with the base portion and moves relative to the base portion; and a cover plate that is slidably engaged with the guide base of the base portion and the sliding plate of the slider portion, wherein the cover plate is configured to selectively cover a slot defined in the sliding plate; wherein when the slider portion moves from a closed position to an open position, the cover plate moves in substantially the same direction as the slider portion due to a friction coefficient between the cover plate and the sliding plate being greater than a friction coefficient between the cover plate and the guide base; wherein the cover plate is further configured to transition from a compressed state to a release state as the slider portion moves from the closed position to the open position and wherein the cover plate further comprises one or more flexible connectors that cause the cover plate to move from the compressed state to the release state, and when the cover plate is in the release state, the cover plate is substantially flush with surfaces of the sliding plate that surround the slot of the sliding plate.
