Abstract:
1. An air duct outlet, comprising: a housing comprising a front wall having an opening therein through which air is allowed to flow; a louver assembly operably coupled with the housing, wherein the louver assembly is configured to adjust a direction of air flowing through the front wall opening, wherein the louver assembly comprises: a joystick remotely positioned relative to the front wall opening such that the joystick does not interfere with air flowing through the front wall opening; a shaft coupled to the joystick and to one of the louvers in the first set, wherein the shaft is configured to pivot the first set of louvers in response to vertical movement of the joystick; and first, second, third and fourth linkages, wherein the first linkage is connected to the joystick, the second linkage is pivotally connected to the first linkage, the second and third linkages are slidably connected, the third linkage is pivotally connected to the fourth linkage, and the fourth linkage is connected to one of the louvers in the second set, wherein the linkages pivot the second set of louvers in response to horizontal movement of the joystick, and wherein, in response to vertical movement of the joystick, the first and second linkages pivot relative to each other, the third and fourth linkages pivot relative to each other, and the second and third linkages slide relative to one another and absorb the vertical movement of the joystick without translating the vertical movement of the joystick to the second set of louvers.
