Abstract
A lift assist mechanism for lifting a large enclosure that is pivotally attached to a body member, between a closed position, an intermediate position, and an open position. The lift assist mechanism includes a swing arm member and an expansible strut member. The swing arm member is pivotally attached to the body member at a first end and to a first end of the strut member at its second end. The second end of strut member is pivotally attached to the enclosure member. The pivot point between the swing arm member and the strut member pushes against a base plate associated with the body member when the enclosure member is in its closed and intermediate positions.
