Definitions

  • This invention relates in general to air distribution units adapted to be associated with an air supply duct and mounted in the wall or ceiling of a room, and is directed more particularly to improvements in the airdeflecting means within the unit which causes the air to emerge from the unit in a predetermined pattern.
  • the invention has special significance in connection with an air distribution unit where a perforated plate covers the outlet end thereof so that when the unit is placed in the ceiling of a room, for example, it will blend with such material as acoustic tile.
  • Air distribution units of this general type have been known heretofore and have been made to operate eflectively within certain predetermined limits. For example, it is often desirable'for the air emerging from the unit to be deflected along the wall or ceiling in which it is mounted. On the other hand, there may be certain installments of this type where it is desirable to have the air emerge in a more direct path outwardly of the unit, or where it is desirable to prevent air from emerging from the unit in one or more directions.
  • the air distribution units heretofore known have not been capable of such a wide range of uses and it is, therefore, a primary object of the present invention to provide such an air distribution unit having adjustable vanes therein capable of being adjusted to direct air emerging therefrom in predetermined directions.
  • Another object of the invention is to provide an air distribution unit which will eifectively direct and distribute air emerging therefrom along the ceiling or wall in which the unit is mounted.
  • a still further object of the invention is to provide in an air distribution unit a novel form of air deflecting means which will give to the unit a greater capacity than has been possible with air deflectors heretofore known and 'used.
  • Still another object of the invention is to provide an air distribution unit with a novel arrangement with inner and outer vanes constituting the air deflecting means therein which may be easily adjusted to obtain the desired results and which will permit a greater amount of air forms of air deflectors, even though the combined area of the vanes is greater than the area of the inlet to the unit and even though the vanes are so positioned as to intercept all of the air stream.
  • FIG. 6 is a plan view of a further modified form of the inner vanes only of the air deflecting means.
  • FIG. 7 is a fragmentary Vertical sectional view taken substantially along the plane of line 6-6 of FIG. 5.
  • an air supply duct is identified by the numeralyl and may be of any suitable and well known construction capable of carrying an air supply to an opening in the wall or ceiling of a room and directing the air outwardly
  • the airdistribution unit is mounted in an opening '4 of a wall or ceiling 5 so that the upstanding collar 2 fits snugly within the duct 1.
  • the unit is mounted in any suitable and well known manner within the opening 4, and in the specific form of the invention shown in FIGS. 1 and 2 the outwardly extending walls 3 terminate in a flange 6 which has a further flange 7 extending therefrom and is adapted'to abut the wallet ceiling 5.
  • the outlet end of the unit formed by'the'outwardly extending walls 3 has a perforated face plate 8 thereover and'mounted thereon with a predetermined number of openings therethrough of suitable size and number which will allow free passage of air outwardly therethrough.
  • An air distribution unit having these elements including the perforated plate covering onthe outlet end thereof is Ewell known in the art, and the construction and mounting thereof in the wall or ceiling of a room may be by any conventional means.
  • the invention herein resides primarily in the form and specific use to which the unit is to be put and the location of that unit in a given wall or ceiling. For example, it may be, and usually is, desirable to produce an air pattern of the emerging air which provides a curtain of air along the wall or ceiling in which the unit is mounted. On the other hand, there may be occasions when it might be desirable to direct some or all of the air in diflerent patterns, or to completely prevent air flow from one or more sides of the unit. Thus, the invention herein is designed to carry out these objects and purposes.
  • FIGS. 1 and 2 there is illustrated a support member 9 which in this case is somewhat narrow and elongated because of the rectangular shape of the air distribution unit.
  • This support member 9 is supported between the inlet and outlet ends of the unit by support means generally indicated by the numerals 10 and 11. 1
  • the support means 19 include elongated diverging leg members 12 and 13 which are bent downwardly at their outer ends as at 14 and 15, so that these outer ends may be welded or otherwise suitably secured to the outwardly tapered side walls.
  • the support means 11 likewise consists of the elongated diverging legs 16 and 17 which terminate at their outer ends in the down-turned portions 18 and 19, respectively, which are also secured to the out wardly tapered side walls in any suitable manner. In the specific form of the invention shown in FIGS. 1 and 2 these elongated members 12, 13, 16, and 17 are'formed of wire.
  • the ends of the legs 12 and 13 meet at 20 at shorter side 28 adjacent thesupport member 9 and 'have openings adapted to receive hinge pins.

  • the. area of the perforated plate 8 which iscovered by the combined area area ofthe inlet and will be intercepted by all of the air from the inlet and by this arrangement the unit has a greater capacity, i.e., a greater amount of air for a given pressure than other air distribution units presently known.
  • vane 22 has its'shorter side 26 adjacentthe support member and its longer side 27 positioned nearer the perforated plate 8.
