Abstract
A storage bin includes a door pivoted to the storage bin for movement between open and closed positions, and a biasing device operably connected to the storage bin and the door for biasing the door as the door nears the open and closed positions. The biasing device includes a spring and a T-shaped shifting anchor connected to the spring that translates and changes a torque arm of a linear spring as the door is moved so that the spring creates a force sufficient to close the door during a last portion of door closure movement and so that the spring creates a force sufficient to open the door during a last portion of door opening movement.
