Swingable rotary screen

In a vehicle having a body provided with a generally rectangular air intake opening, said vehicle embodying an internal combustion engine having a fixed heat exchange radiator, and an air conditioning system including a movable heat exchange condenser core, said radiator being fixedly mounted within said body in the vicinity of said opening and said core being normally disposed outwardly of the radiator immediately behind said opening and within said body, a generally rectangular panel having one edge thereof hingedly connected to said body and capable of swinging movement between a normally closed position wherein it covers the opening and an open extended position wherein it uncovers the opening, said core being pivotally mounted on said body for swinging movement between its normal position and an extended position wherein it projects outwardly of said opening, said panel being formed with a relatively large central opening therein, a rotary air screen of the blanking baffle type carried by said panel and cooperating with said central opening, and means operatively connecting said panel and condenser core for swinging movement in unison between their normal and extended positions, said means comprising at least one tie rod pivotally connected at one end to the panel and at the other end to the outer edge region of the core, and wherein the panel and condenser core are pivoted to the vehicle body for swinging movement about respective closely spaced parallel axes and the portion of the body which extends between said axes, in combination with said core, panel and tie rod, define, in effect, an elongated four-bar linkage which, when the panel and core are in their normal positions is substantially collapsed, and when the panel and core are extended define a trapezoid.
