Description
Background of the Invention
1. Field Of The Invention
The present invention deals with the field of devices for deflecting air as it is emitted from air outlets. These devices are normally used with air conditioning or heating vents which distribute hot or cold air for controlling air temperature within a building.
Under normal circumstances especially when cold air is distributed through air outlets or air vents in a ceiling, the laminar flow of air causes drafts upon individuals which may be seated adjacent to or below these air vents. The present invention pertains to the field of devices for dispersing the air more evenly throughout the room relatively quickly and by preventing drafts caused by this emitted air.

Summary of the Invention
The present invention provides an air deflector means being particularly usable with air outlets defined in dropped ceiling constructions. All such dropped ceiling constructions include a framework of inverted T-shaped support members with the ceiling panels supported and suspended therebetween.
The deflection apparatus of the present invention includes a suspension bracket having a hook means at the upper end thereof which is selectively securable with respect to the inverted T-shaped support members of the dropped ceiling. Preferably this suspension bracket will be of a resilient material such as plastic to facilitate bending or flexing for initial securement with respect to the T-shaped support members.
The suspension bracket means further includes a rod means at the lower end of each of the suspension brackets which extends downwardly with respect to the hook at the upper end thereof. A plurality of cross members are positioned extending laterally in spaced relation with respect to one another along the rod. Preferably these cross members are spaced from one another at approximately 9/16" or approximately 1/16" greater than the thickness of the deflecting shield which will be mounted therebetween.
The deflecting shield means itself is secured with respect to the suspension bracket means and extends horizontally therebetween and is spaced downwardly from the ceiling panel and air outlets thereabove. In this manner air being emitted through the air outlets and striking the upper surface of the deflecting shield is deflected outwardly for dispersal preventing drafts and insuring mixing of the conditioned air with respect to the remaining room environment. The deflecting sheild means preferably includes a plurality of slot means therein adapted to receive the rod means and the cross members extended therethrough. The means for deflecting air further include the plurality of cover caps which are positionable extending over the lower portions of the rod means and the lower individual cross member means which extend below the deflecting shield means to provide an aesthetically pleasing look for the ceiling fixture of the present invention.
The present invention may include one or more vane members which will facilitate the deflecting of air when the present invention is utilized adjacent to wall or corner areas. In this configuration the deflecting shield will define a plurality of grooves in the upper surface thereof which are adapted to receive the vanes extending therein for securement with respect to the upper deflecting area itself.
The vane means may be interlocked with respect to one another by the definition slits at various angles therein to facilitate the urging of fluid flow of air other than evenly downwardly over the four sides of the deflecting shield. When the present invention is utilized adjacent to a wall, it may be desirable to have most of the conditioned air fall over the edges of the deflecting shield which are not adjacent to the wall. This is true because the wall tends to confine the air falling off the edge of the deflecting shield thereadjacent to create a draft which is exactly what the present invention is designed to alleviate. When utilized adjacent to corners, there are two adjacent walls and therefore two adjacent shield edges must be somewhat shielded from allowing conditioned air to flow thereover and therefore two interlocking vane members angularly oriented with respect to the upper surface of a deflecting member would achieve this purpose. Preferably the vanes can be oriented with respect to the upper surface of the deflecting shield at approximately an angle of 60.degree.. This angle can be determined by the angle of the slits in the vanes themselves or can be determined by the angular orientation of the groove defined in the upper surface of the shield.
Preferably in the present invention the deflecting shield means can be approximately square or rectangular in shape. Also it is preferable that the air deflecting means is of material similar to the ceiling panels. Normally such panels are 1/2" in thickness which cooperates well with the preferred 9/16" distance for the intervening spaces defined between adjacent cross members.
The cover cap means in order to aid in providing an aesthetically pleasing external appearance will preferably be shaped hemispherically. Also it is preferable that the cover cap means will be made of a material somewhat denser than the material of the deflecting shield itself.
In the preferred configuration the air deflecting means will include four individual suspension brackets each fixedly secured at their upper end to an adjacent portion of the T-shaped dropped ceiling suspension framework.
Also the deflecting shield will preferably define four individual slot members oriented perpendicularly with respect to the cross member means. That is, as each bracket is extending downwardly from the inverted T-shaped framework the cross members of the rod sections thereof will be oriented perpendicularly with respect to each of the four slots defined in the deflecting shield means. Since the brackets themselves are of a flexibly resilient material which may be plastic they can be initially deformed slightly to allow the rod means and some of the individual cross members to extend through the slot means and then can be released such that they will resiliently spring back to the original shape and thereby lock the deflecting shield in place.
Once the deflecting shield is locked in place in the above manner the excess portion of the rod means and the excess cross members extending below the deflecting shield can be removed. For this purpose a plurality of frangible sections can be positioned immediately below each laterally extending cross member to facilitate removal of the excess portion of the rod. In this manner only a single cross member will remain below the deflecting shield to allow the hemispherical cover plate means to be positioned thereon to provide an overall final aesthetically pleasing configuration. During installation, of course, any of the cross members can be chosen as the final cross member thereby allowing the adjustable aspect wherein the installer will have the capability of positioning the deflecting shield at any one of several pre-chosen distances from the air vent positioned thereabove so that the downward air flow will strike the deflecting shield in such a manner as to give the optimum of air dispersal and air current pattern to the area served by this air shield.
Preferably the hook at the upper end of the bracket will include a loop member which includes a cut section in the lower portion thereof. The inverted T-shaped support member can be positioned extending through the cut of the loop member to thereby detachably secure the loop member and the hook means to the inverted T-shaped framework merely by slightly deforming the resilient hook means. In this manner a detachable securement of the loop member with respect to the inverted T-shaped support framework is easily achieved.

Detailed Description of the Preferred Embodiment
The present invention provides an air deflecting means for use with air outlets 10 defined within dropped ceiling constructions 12. Such ceiling constructions normally include inverted T-shaped support members 14 which define ceiling panels 16 extending therebetween. Air 18 exits from outlet 10 and normally when this air is cooled creates excessive cooling drafts within the environment of the room.
To overcome this problem a deflecting shield means 28 is suspended extending horizontally across the path of movement of this emitted air 18. Deflecting shield means 28 is secured with respect to the suspension bracket means 20. Each bracket means 20 includes a hook means 22 at the uppermost end thereof which is secured to the inverted T-shaped support member 14. A rod means 24 extends downwardly from the hook means 22 and includes a plurality of cross member means 26 located therealong.
Deflecting shield means 28 preferably defines a plurality of slot means 30 therein which are adapted to receive rod means 24 and cross member means 26 extending therethrough. In the chosen orientation cross member means 26 will be perpendicularly oriented with respect to slot means 30 to thereby prevent slipping of the cross member means 26 vertically through the slot means 30 after installation.
Preferably the suspension brackets 20 will be of resilient material to facilitate temporary flexing thereof to allow securement of the hook means 22 with respect to the inverted T-shaped support members 14 while at the same time allowing insertion of the rod means 24 and cross member means 26 through the slot means 30 temporarily. After the cross member means 26 is released they will snap back to the original orientation which is perpendicular with respect to slot means 30 thereby preventing slipping of the suspension bracket 20 through the slot means 30.
In a preferred configuration a frangible section 42 will be positioned immediately below each cross member means 26 to facilitate breaking of the cross member therealong. Once the deflecting shield means 28 is in place one of the cross member means 26 will be positioned immediately below the shield means 28. All of the remaining cross member means 28 other than the one in abutment with the bottom surface of the deflecting shield 28 will no longer be needed and therefore cutting or breaking of the rod means 24 immediately below the last cross member means 26 is advantageous in order to provide an overall aesthetically pleasing design. This cutting or breaking along the frangible section 42 can be achieved by a cutter or by deforming the rod means 24 back and forth to fatigue the resilient material for breaking thereof.
To further provide an aesthetically pleasing overall appearance a hemispherical cover cap means 32 may be included of a somewhat dense material such that it can be pushed upwardly and will slightly deform and thereby will adhere to the remaining cross member means 26 extending laterally below the lower surface of deflecting shield means 28.
The cross member means will define a central axis 36 thereof which preferably is perpendicular with respect to the axis of the slot means 30. In the preferred configuration as shown in FIG. 2 this central axis of the cross member means 36 will each extend inwardly through the center point 34 of deflecting shield means 28. In this orientation the deflecting shield will be safely and securely held in suspension by the bracket means 20 in spaced relation with respect to dropped ceiling 12.
The deflecting shield means 28 will preferably be of a material similar to the ceiling configuration such that it will aesthetically blend therein. Normally such ceiling materials which normally are used also for the ceiling panel 16 would be of a thickness of approximately 1/2". For this reason the intervening spaces 44 defined between adjacent cross member means 26 will preferably be approximately 9/16" to facilitate placement of the deflecting shield 28 between the remaining lowermost cross member means and the next one immediately thereabove.
The upper end of suspension bracket means 20 will preferably be formed as a loop member 38 which will include a cut section 40 in the lower portion thereof as best shown in the cross section of FIG. 3. This cut section will be adapted to receive a portion of the inverted T-shaped support member 14 therethrough. To facilitate this detachable securement when the suspension bracket 20 is of a resilient material such as plastic the installer will normally resiliently deform the loop member 38 thereby slightly increasing the open portion of cut section 40 allowing a portion of the inverted T-shaped support member 14 to extend therein. Once the inverted T-shaped support member is in place the installer can release the loop member 38 thereby allowing the cut section 40 to exert a bias against the inverted T-shaped support member to facilitate gripping thereof.
With this configuration the installer can choose to place the deflecting shield 28 between any two of the adjacent cross member means 26. Thus the distance can be varied greatly between the deflecting shield means 28 and the air outlet 10. This can allow for a more aesthetically pleasing final configuration or can allow for a more efficient placement of the deflecting shield 28. This can be left to the discretion of the installer who will have the best information available due to being on the spot at the time of installation.
The configuration shown in FIG. 7 is particularly usable when the air vent to which the present invention is to be utilized herewith is located adjacent to a wall or corner area. With such areas, as the air travels downwardly and contacts the deflecting shield as always approximately 25 percent of the air will travel over each of the four edges of the deflecting shield. The portions of the conditioned air which travel over deflecting shield 28 and exit over the edge adjacent to the wall will not be allowed to be dispersed outwardly and further due to the intervening wall area. The wall will tend to guide this air downwardly and will cause a downward draft to anyone located therebelow. For this reason vane means is utilized in the present invention comprising one or more vane members 46. These members are adapted to be angularly oriented with respect to the upper surface of deflecting shield 28 in such a manner as to guide air away from any wall area to which the present invention may be positioned adjacent.
The vane members 46 are angularly oriented with respect to the upper surface of the deflecting shield 28 preferably at an angle of approximately 60.degree.. This angle can be determined by the angle of a groove means 50 which preferably is defined in the upper surface of the deflecting shield. This groove being oriented approximately 60.degree. which is adapted to receive the vane means extending therein will thereby orient the vane automatically at approximately 60.degree. with respect to the plane of the deflecting field.
If the present invention is utilized in corner areas, this problem is more pronounced and as such the vane members preferably can be used in groupings of two as shown in FIGS. 6 and 7 more specifically. Vane members 46 may define a plurality of slit means 48 therein as shown in FIG. 4 such as to allow the individual vanes 46 to be engageable with respect to one another and positionable extending within perpendicularly oriented grooves defined in the deflecting shield 28. Also vane members 46 may be positioned with the upper edges thereof in abutment with respect to the suspension bracket for stabilization thereof.
With this configuration the present invention has a universal utility and can be used with a ceiling air duct regardless of its location. If the duct is located generally in the central area of a ceiling the conventional deflecting means of the present invention can be utilized. However if the air duct is positioned adjacent to a wall or corner structure the present invention can be used with one or more of the vane members 46 and in such a manner provide a means for dispersing of air emitted from an air vent regardless of the specific location of the air vent in the ceiling area of the room whether it be adjacent to walls, corners or centrally located.
It should be appreciated that the present invention, minus the vanes, could be hung from nearly any location in a dropped ceiling construction. In that context it could assume the application of a light duty suspended shelf fromtthe ceiling above. This shelf could support flowers, decorative things or other items. Also the suspension bracket could function as a hanger in virtually any location secured to a dropped ceiling construction in such a manner that any hanging items could be suspended therefrom.
While particular embodiments of this invention have been shown in the drawings and described above, it will be apparent, that many changes may be made in the form, arrangement and positioning of the various elements of the combination. In consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention.
