    Abstract: A handle mechanism includes a gear drive having an interior end and an exterior end; an inside handle fixed to the interior end; a button; a finger; a handle drive; an outside handle; and a spring. The button has an interior end and an exterior end, which is positioned within the exterior end of the gear drive. The handle drive is positioned within the exterior end of the gear drive and is rotatable relative thereto. The outside handle and the handle drive rotate together. The outside handle moves between a first position, wherein it is constrained from rotation, and a second position. The finger is fixed to the exterior end of the button, which moves between a first position, wherein the finger causes the gear drive and the handle drive to rotate together, and a second position. The spring biases the button and the outside handle toward their first positions.

    Abstract: The aluminum alloy product of an embodiment of the present invention includes a pair of outer regions and an inner region positioned between the outer regions. A first concentration of eutectic forming alloying elements in the inner region is less than a second concentration of eutectic forming alloying elements in each of the outer regions. Further, the aluminum alloy product has a delta r value of 0 to 0.10. The delta r value is calculated as follows: Absolute Value [(r_L+r_LT−2*r_45)/2] and the r_L is an r value in a longitudinal direction of the aluminum alloy product, the r_LT is an r value in a transverse direction of the aluminum alloy product, and the r_45 is an r value in a 45 degree direction of the aluminum alloy product.
