Abstract
A spring assembly for a handle set assembly includes a housing and a gear rotatably positioned within the housing. The gear has a default position and at least one actuated rotated position. The spring assembly includes at least one rack positioned within the housing. The at least one rack is movable in a rack displacement direction that is normal to the axis of rotation of the gear in response to rotation of the gear between a neutral position and a displaced position. The spring assembly includes a slider positioned at a first end of the at least one rack, the slider being slidable along the rack displacement direction. The spring assembly includes at least one spring captured between the housing and slider. The at least one spring is positioned to apply a spring force to the at least one rack toward the neutral position when the at least one rack is in the displaced position.
