  • Floor register grill
    Patent number: 5163871
    Abstract: An air register grill includes a plurality of air directing vanes. Each air directing vane includes an air directing curve which meets one side of the grill at a substantially 90.degree. angle. Opposing each air directing side is a relief side which generally mirrors the shape of the air directing side. This configuration provides an air stream which exits the grill at a generally 90.degree. angle with the grill. Furthermore, air flow is not seriously impeded and the resultant grill structure provides an aesthetically pleasing design.
