ABSTRACT:
A corner vent for windshields having rearwardly extending panels utilizes a hollow corner post having a concave inner surface with one or more adjustable ventilators therethrough and communicating with the interior of the post. A vent door is formed in an outer convex surface of the post and hingedly attached adjacent a rearward edge of the post. A lever attached to an inside surface of the vent door extends through the inner surface of the post to open and close the vent door. In the closed position, the post gives the appearance of a solid post, and in the open position, air flow is directed into the interior and through the ventilator. The corner vent is applicable to power boats and the like.
