A hinge assembly includes a housing member, a lever member, a traveling member and a biasing member. The housing member includes a channel and a pivot. The lever member includes an outer portion, an inner portion, and a first intermediate point located therebetween. The lever member is pivotally coupled to the pivot at the first intermediate point. The traveling member includes a main portion that is configured to extend substantially along the housing member. A second intermediate point is located on the main portion, and the inner portion of the lever member is pivotally coupled to the second intermediate point. The main portion includes a sliding block and at least one grooved wheel at an end. The sliding block is configured to travel the channel sliding between the side walls, and at least one of the sidewalls includes a rail area for the at least wheel to roll against.
