Patent attributes
A hinge assembly has a pintle, a rotating bracket, a sliding bracket, a mounting bracket, a compression assembly and an elastic member. The rotating bracket is mounted rotatably around the shaft and has a latching portion. The sliding bracket is attached securely to the pintle and has a track. The mounting bracket and a latching arm. The latching arm selectively presses against the latching portion to hold the hinge closed. The compression assembly is mounted around and expands when the pintle is rotated to close. The elastic member is compressed by expansion of the compression assembly so automatically rotates the pintle to open. Therefore, with the hinge mounted in an electronic device, when the latching portion is slid out of the latching arm, the hinge is forced to open by the elastic member and compression assembly so a cover pops up and is opened easily.
