An air deflector attachment for heating and/or cooling ducts opening through the floor wall or ceiling to move the column of air outwardly from an adjacent wall or ceiling permitting the curtains, furniture, persons and objects to be in the room without being directly contacted by the column of air. The deflector includes serpentine inner and outer walls mounted in serpentine tracks formed in spaced parallel end walls. The end walls are provided with serpentine tracks on each side face thereof to permit the joining together of a plurality of side walls when an especially long deflector is required. The deflector offsets the path of the column of air but retains its direction characteristic for efficiency in hot and cold air distribution.

AIR DEFLECTOR ATTACHMENT BACKGROUND or THE INVENTION FIELD or THE INVENTION SUMMARY OF THE INVENTION The deflector consists of a serpentine conduit of generally rectangular horizontal cross-section having a pair of inner and outer serpentine side walls arranged in spaced apart relation and secured in spaced apart serpentine tracks formed on opposed end walls. The deflector offsets the column of air issuing from the register so that it avoids objects which would otherwise be in its path.
The primary object of the invention is to provide a deflector attachment for air registers of a heating and cooling system which will deflect the air away from objects otherwise in its path, while maintaining the required distribution of air in the room.
' Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of the invention;
FIG. 2 is a front elevation of the invention;
FIG. 3 is a rear elevation of the invention;
FIG. 4 is a bottom plan view of the invention; and
FIG. 5 is a transverse sectional view showing the invention in place on a floor mounted air register.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral indicates generally an air deflector constructed in accordance with the invention.
The deflector 10 includes a pair of spaced parallel end walls 1 1, 12 each having a horizontal bottom edge 13 and a sloping top edge 14. The inner edge of the side walls ll, 12 are each provided with a serpentine track member 15 and the outer edge of the end walls 11, 12 are each provided with a serpentine track member 16. The serpentine track members 15, 16 are provided with track grooves 17 on the opposite side faces thereof as can be clearly seen in FIG. 4.
A generally horizontal foot 18 is integrally formed on each of the end walls 1 1 along the horizontal lower edge 13 thereof. A serpentine front panel 19 extends between the serpentine track members 16 of the end walls 11, 12 and is fitted into the track groove 17 of each. A serpentine rear panel 20 is arranged in spaced relation to the front panel 19 and extends between the serpentine track members 15 of the end walls 11,
12 fitted into the track grooves 17 of each.
In FIG. 5 the deflector 10 is illustrated in operative position in a room which includes a floor 21, side wall 22, window 23, andwindow drapes 24. A floor register is positioned beneath the window 23 to emit air from a conduit 26 which opens through the floor 21. In the normal operation of the forced air heating or cooling system the position of the register 25 is such that the drapes are in the column of air moving through the register 25 and hence not only is the distribution of air disturbed by the drapes, but in addition the drapes are quickly soiled due to dirt particles which are carried in the air column. The deflector 10 offsets the air column outwardly to completely miss the drapes 24. The sloping upper edge 14 of the end walls ll, 12 have an angle of approximately 17 to the horizontal causing the air column to diverge slightly outwardly from the vertical.
The end walls 11, 12, track members 15, 16, and side panels 19, 20 are formed of any desired material such as plastic and the side panels 19, 20 are secured to the track members 15, 16 with any desired adhesive. The feet 18 of the end walls ll, 12
are adhesively secured to the register 25 or to the floor 21 in order to maintain the deflector 10 in its correct position.
It should be noted that each of the track members 15, 16
' have track grooves 17 on each side face thereof so that in the case of exceptionally long registers 25 additional lengths of side panels 19, 20 can be attached to an end wall 11 or 12 to lengthen the deflector 10 as required. Obviously when additional lengths of side panels 19, 20 are used one additional end wall 11 is required for each length of side panels 19, 20 which are added.
Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
What is claimed is:
l. A self-contained air deflector overlying horizontal registers of a forced air heating and/or cooling system comprising a pair of spaced parallel generally flat end walls, a serpentine track member integrally formed on each of the opposite side edges of each of said end walls, serpentine inner and outer side panels arranged in spaced apart generally parallel relation extending between and having each side edge thereof secured in one of said track members, and a foot integrally formed on a bottom edge of each of said end walls for overlying engagement with said horizontal register.
2. A device as claimed in claim 1 wherein each of said track members is provided with opposed track grooves on opposite side faces thereof with said side panels engaged in at least one of said track grooves.
3. A device as claimed in claim 2 wherein said inner side panel extends above said outer side panel to provide an outwardly sloping outlet to said deflector.
4. A device as claimed in claim 3 wherein a pair of inner side panels and a pair of outer side panels are secured on opposite sides of one of said end walls to extend outwardly therefrom.
