ABSTRACT:
A manually adjustable forced air-flow deflector for use on a register of a forced air heating system. The forced air-flow deflector comprises a back plate having a first end and a second end, with the first and second end plates secured to the respective first and second end of the back plate so as to project forwardly in generally transverse relation with respect to the back plate. The forced air-flow deflector further comprises a movable air-flow guiding plate and retaining means therefor. The movable air-flow guiding plate is retained in selectively movable relation by a retaining means comprising a first, second and third pairs of directly opposed grooves disposed one in each of the end plates. The first pair of grooves retains the air-flow guiding plate in generally upstanding relation at the front of the end plates. The second pair of grooves retains the air-flow guiding plate at a central portion of the end plates in angled relation, upwardly directed away from the back plate. The third pair of grooves retains the air-flow guiding plate in generally horizontal relation at the top of the end plates.
