Patent ID: 7770261

Claim:
A foldable electronic device comprising: a first housing element having a proximal end and a distal end; a second housing element having a proximal end and a distal end, a knuckle receiving slot is defined at the proximal end and a pivot assembly extending about opposing sides of the receiving slot, the pivot assembly comprises a first cavity on a first side of the knuckle receiving slot, and a second cavity on the second side of the knuckle receiving slot; and the first housing element pivotably coupled to the second housing element at the proximal ends thereof by a knuckle assembly comprising: a base member attached to the first housing element; a knuckle positioned in the knuckle receiving slot of the second housing element, the knuckle formed with and extending outwardly from the base, the knuckle having opposing side surfaces; and opposing spigot members extending away from the opposing side surfaces of the knuckle and into the pivot assembly of the second housing element on opposing sides of the knuckle receiving slot, to, in turn, allow pivoting of the first housing element relative to the second housing element about an axis extending through the opposing spigot members; wherein the first cavity structurally configured to receive at least a portion of the first spigot and the second cavity structurally configured to receive at least a portion of the second spigot, wherein each spigot is rotatable within the respective cavity so as to rotate about the axis, and wherein a bushing member interfacing between one of the first and second cavity of the pivot assembly and one of the first and second spigot members, the bushing member includes an inner bore and an outer surface, one of the spigot members extending into the inner bore of the busing member, and the outer surface extending into the respective one of the first and second cavity.
