Patent ID: 8072749

Claim:
A cover assembly for a portable electronic device comprising: a cover for the portable electronic device, the cover comprising: two cover extensions extending substantially perpendicular from the cover, each of the two cover extensions having an abutment at an end of the cover extension facing each other, the cover extensions having a span width therebetween, the span width substantially corresponding to a width of the portable electronic device; an angular spring having a center and two wings with upwards arcuate ends spanning substantially the span width, each of the wings forming a bias angle relative to a line extending from one of the upward arcuate ends to the other; two housing extensions extending from a surface of the portable electronic device, each of the housing extensions having a protrusion mating the corresponding abutment of the cover extension, and a guide having a form substantially corresponding the upwards arcuate end of the angular spring; wherein when a force is applied to the center of the angular spring, the bias angle decreases and the upwards arcuate ends are urged upwards, thereby causing the abutments moving outwards, and unlocking the protrusions.
