9 Claims. (Cl. 9840) This invention relates to ventilating apparatus, and has particular reference to the combination with an obstruction to the flow of a stream of air, of means to guide the air stream in a desired manner about the obstruction.

in the ventilating art there frequently are encountered conditions where an air outlet device must of necessity be mounted in such relationship to a member, such as a beam, a wall offset, a light fixture or the like, that the member serves to obstruct air flowing from the device and thereby prevents the air from following a most effective ventilating path of flow. Alternatively, there frequently are encountered conditions where a member, such as a light fixture or the like, must of necessity be mounted in such relationship to an already installed air outlet device as to obstruct flow of air from the latter and prevent the air from following a most effective ventilating path of flow.

The object of the present invention is to combine with an obstruction of any kind to the flow of air from an air outlet device, means to guide the air in a desired manner about the obstruction so as to, in eifect, eliminate interference of the obstruction with flow of the air in a most effective ventilating path.

With the foregoing general object in view, the invention consists in the novel combination and arrangement of air flow control means relative to an obstruction to flow of air from an air outlet device, as will be-hereinafter more fully described, illustrated by way of example in the accompanying drawings and defined in the appended claims.

in the accompanying drawings, wherein like characters of reference denote corresponding parts in the different views:

Figs. 1, 2, 3 and 4 are sectional views illustrating different adaptations of means to cause air delivered from an air outlet device to flow in a desired manner about an obstruction to the natural path of flow of the air from the outlet device.

Referring to the drawings in detail, 10 designates a wall of aroom or other enclosure, 11 designates an air outlet device which may be mounted either in the wall 10, as shown, or, if desired, adjacent thereto, for delivering air from an air supply duct- (not shown) into the room or enclosure for heating, cooling, ventilating or any other purpose and in such manner that a large proportion of the air travels along the wall 10, due to certain extent to its natural tendency to cling to said wall, and 12 designates a member, such as a beam, a wall offset, a light fixture or the like, which projects from said Wall 10 and acts as an obstruction to the natural path of flow of the air along said wall.

In most instances where a member, such as the member 12, obstructs flow of air along a wall from an air outlet device, it serves to deflect the air away from the wall and prevents the air from following a path which best adapts it to serve its purpose. In other words, in most instances where a member obstructs flow of air from an air outlet device along a wall, it usually is desirable that the air continue to flow along the wall at the side of the member remote from the air outlet device. Accordingly, the present invention consists in the use of a vane or vanes 13 at a corner or corners of the member 12 for directing air around said member and thus, in effect, eliminating said member as an obstruction to flow of the air in a path best adapting it to accomplish its purpose.

in Fig. lof the drawings the wall 10 may be presumed to be either a ceiling or a side wall, the air outlet device '11 is of a type which is mounted in a recess in said wall and acts to cause a large proportion of the total amount of air delivered therefrom to flow along said wall, and the member 12 may be presumed to be either a beam, a light fixture or the like extending downwardly from said wall, or a column, offset or the like projecting inwardly from said wall in the path of flow of air from the air outlet device 11. In the absence of means to direct the air around the member 12, said member would intercept the air and deflect it away from the wall 10, with the result that there would be no flow of air from the device 11 along the wall at the side of the member 12 remote from said device 11. in fact, deflection of the supplied air by the member 12 away from the wall 10, would induce, at the side of the member 12 remote from the device 11, flow of enclosure air in the same general direction as the direction of flow of the deflected supplied air. Now assuming that the air delivered by the device 11, in order best to serve its purpose, should pass around the member 12 and continue its original direction of flow along the wall 16 at the side of said member 12 remote from said outlet device, the present invention consists in mounting a vane 13 adjacent to each of the two front corners, 14, 14 of said member 12 to cause the applied air to flow in this desired manner.

The vanes 13 may be of any suitable lengths and are of substantially L-shape in cross section so that each includes two flanges 15, 15 which are disposed at substantially right angles to each other and which preferably are joined together by a rounded corner 16. In mounting said vanes adjacent to the front corners 14, 14 of the member 12, one flange 15 of each vane is spaced from disposed substantially parallel to the front face of 'the member 12 in overlapping relationship thereto, and the remaining two flanges 15 of said vanes are spaced from and disposed substantially parallel and in overlapping relationship 'to the two side faces, respectively, of said member 12. Thus, said vanes 13 cooperate with the member 12 to provide passageways 17 which extend around the front corners 14, 14 of said member and which cross sectionally, are open at their ends for flow of air into and from the same. It will thus be apparent that air flowing from the air outlet device 11 along the wall 10 toward the member 12 and deflected away from said wall by the side face of said member 12.nearer said air outlet device, will pass through the passageway 17 at the front corner 14 of said member 12 nearer said outlet device and will have its direction of flow changed by the vanes ofthe member 13 located at'sa'id corner of said member 12 sothatthe air then-will flow substantially parallel to and across the front face of said member 12. The air then will pass through the passageway 17 at the front corner 14 of the member 12 remote from the air outlet device 11 and again will have its direction of flow changed by the vanes of the member 13 located at the latter corner of said member 12 so that the air then will flow along the side face of the member 12 remote from the air outlet device 11 toward the wall 10, by which it will be intercepted and again directed in its original direction of flow along said wall. As a result, the member 12 will, in effect, be eliminated as an obstruction to the path of flow of the air from the air outlet device 11 along the Wall 10,

as will be apparent from the arrows a which indicate'the path of flow or the air around said member 12.

Should the member 12 be of shallow depth and project only a short distance from the wall 19, it may not be necessary to employ a vane 13 at the front corner'14 of saidmember 12 remotefrom the air outlet device 11 to direct the air along the remote side of said member 12 toward the wall 10.. in that event only a single vane .13 located at the front corner 14-of said member 12 nearer the-.air-outlet device 11 need be employed to direct the air across thefront face of said member 12.

Ininstances where the side of the member 12'nearer the airoutletidevice 11 is of a nature such that it. might acttodeflect the supplied air in most any direction, or directions, or might even permit the supplied air to enter said member, as, for example, in instances where said member is in the form of a light fixture or the like having "vention as applied'to ab'a'ggage" rack or'simil'a'r member irregular sides possibly open at certain points. as il1nstrated in Fig. .2 of the drawings, it may be desirable also to .employavane 13 similar to one of the vanes 13 at. the corner v18 between the wall 10 and the side face of saidmemben 12 nearer the air outlet device 11 to assist in directing air delivered from said air outlet device itsI-flanges1 disposed either against or adjacent'to and extending parallel or substantially parallel to the said side face of the member 12. Thus, said vane 13 obviously will'serve to deflect the supplied air forwardly from the wall along the said side face of the member 12 so that it willbe substantially unaffected by any irregularity of said side face and will be acted upon by the vane or vanes 13 at the front corner or corners of the member 12 in the same manner as set forth in connection with Fig. 1 of the drawings. A companion vane 13 may, if desired, beinounted in the same manner as said first mentioned vane 13*- at the corner 18'between .the wall 10 and the side' of the memberI12 remote from the air outlet device 'illto assist in promoting flow of supplied air aroundsaid member'12, particularly in instances whereia vane 13 is provided 'at' the front corner of the member 12 remote Tfrdr'n'the air outlet device .11 to cause the supplied air 'toiflow along the farsidefaceof saidmember 12 toward the'wa'll110.

In some instances the member :12, instead 10f being of rectangular shape in cross lsection, as. shown. in. Figs. '1 nd '2 of the drawings, may beofsubstantially -.V -shape .in'ci'oss section as shown infFig. 3 of thedrawings. In

j thateve'nt, only a single vane 1 3b'of substantially V-shape in cross. section need be employed to direct-air stlPPlied 'fi'dm'the air outlet device .11 around saidimember 12. Inother words, asingle vane 13 ofsubstantially V-shape inci'oss section maybe mounted. at the apexof the member 12 with its flangesil5 15 spaced'from and extending substantially parallel to the inclinedside faces, respectively, ofsaid member 12 to provide a passageway 17 which cros's sectionallyis open.at its endsand extends around theapex of said member 12, .asillustrated in.-Fig.

3. Air .deflect'e'dliforwardlyf'from the wall .10 bythe inclinedside-faceof 'thek'nernbefn nearer the air outlet device '11 will "pass through'thefpa'ss'age".vay'I7 and by the-wanes of*themember"13 will'have its'direction of flowchanged so-"that it will'fiowalongthe' inclined side faceiof- 'saidj member 12' remote from the air outlet device 11 toward the wall -10-to continue itsoriginal' direction offlowalongsaid wall. If desired, other vanes maybe employed at the corners between thewall-10 and the inclined side faces 'of the'member 12 illustrated in-Figk3 inthe same .manneras the vanes employed at the correspending corners .in the. example of the invention illustratedin Fig. 2 of the drawings to assist indirectingthe air arountha member 12. such as is illustrated in Figj-fi .-,F.-ig.-4 of the 1 drawings illustrate'sathe utility ofsthe inthe like designated generally as 21. The air outlet device 7 31 is illustrated as being mounted as usual in the ceiling 22 of the enclosure so as to direct air across the ceiling toward and downwardly over the side Wall 23 of the enclosure. The member 20 acts, of course, as an obstruction to downward flow of the air over the side wall 23 and serves to deflect the air inwardly so that ordinarily the air would not reach the side of the enclosure'jbeneath said member 2%. However, in accordance With the present invention, a vane 13 of substantially'U-shape in crosssection is mounted in spacedrelationship to the inner edge of the member .20 to provide a passageway 1? of substantially U-shape in cross section extending around the inner edge of said member 20. Said passageway, considered cross sectionally, is open atits ends for flow of the air therethrough, and the upper portionof the vane 13 is disposed to intercept air flowing inwardly across the top of the member 20 and to direct it through said passageway 17. The air thus is caused to flow across the under side of the member 29 toward the side wall 23 of the enclosure so as to reach the space beneath said memberv 20.

The vaneor vanes used in any particular instance may, of course, be formedfrom metal, glass, plastic, or any other suitable opaque, translucent or transparent material. 7

From the foregoing description considered in connection with the accompanying drawings, it is believed that the invention will be clearly understood and its advantages appreciated. It is desired to emphasize, however, that the illustrated adaptations of the invention are merely by way of example and are not to be construed as limiting, since. the invention within its spirit and scope as defined in the appended claims, may readily be adapted to the solution of may other air flow control problems encountered in the ventilating art.
