Definitions
- FG. l is a fragmentary top plan View of an embodiment of the air diffuser of this invention.
- FIG. 2 is a fragmentary section View of the air diffuser taken substantially along the line 2 2 of FIG. l; and FIG. 3 is a perspective View of a mounting bracket incorporated in the air diffuser of FG. 1.
- ran air diffuser generally denoted :by the numeral 1t) which is adapted to be connected to an air distributing and Ventilating system through a conduit, not shown, for directing heating or Ventilating air from the system to the diffuser circular inlet opening 12.
- the air ⁇ diffuser has an annular diffuser ring or housing 14 which has a central frustoconioal portion 16, two concentric cylindrical portions 18, 20 defining the inlet opening 12 and an outlet opening 13, and an outwardly flaring flange portion 22 that is adapted for overlying and engaging a ceiling panel (not shown) having an opening through which the diffuser ring 14 extends.
- an air deflector subassem-bly 35i that preferably has three radially extending hanger aims 32 that lie in angularly spaced planes extending radially from the diffuser axis and lwhich are centrally deformed and Welded together or otherwise secured to provide a central triangularly Shaped opening 33 through which a shaft (not shown) attached to a conventional air damper (not shown) may extend for convenient adjustment of the damper.
- the passage 37 defined by the outer deflector 34 and the frustoconical portion 16 of the diffuser ring 14 provides a primary air passage for directing air from the upper circular opening 12 Patented Oct. V22., 1963 downwardly and Ioutwardly to the air discharge opening for-med between the cylindrical portion 20 and the deflector lip 35.
- the passage 37 will have an increasing crosssectional area toward the air discharge opening which will have the effect of reducing the velocity of the air as it passes through the diffuser toward the discharge opening.
- a circular inner dellector 40 having a generally cup-shaped central portion terminating in an outwardly and upwardly extending lip 42.
- each of the hanger arms is provided with Ian integral axially extending Vleg 44 that has an extension 46 received Within and upset upon the deflector 40.
- the air passage 48 formed between the deflectors 34 and 40 provides aisecondary air passage from which air in the embodiment shown is discharged at Ian angle of approximately 60 with the axis of the diffuser.
- Each of the hook assemblies comprises an inwardly .facing hook mernbe-r 54 and a spring finger 52 that conforms to the inner surface of the hook member 54, and the assembly is -fixed to the housing 14 as by rivets 60 so that the spring finger 52 is capable of flexible movement away from the 'hook member 54.
- Each hook member 54 has an outwardly extending radial slot 56 that is adapted to receive the outer ends of the hanger ⁇ arms 32 for preventing relative rotational movement of the defiector ⁇ subassernbly 30' within the housing 14.
- the .outer end of each hanger arm 32 is provided with 'an axially extending saw-tooth shaped edge having tapered portions S9 and supporting abutment portions 5'1, and the spring 52 is positioned to overlie the -slot 56 for engagement with the tapered portions 56 fand supporting abutment portions 51 at the juncture thereof.
- the adjustment of the deflector subassembly 311 toward the inlet opening 12 or upwardly when the diffuser is installed in la ceiling panel, is accomplished by manually pushing the subassembly toward the inlet opening 12 until the ends of the spring fingers 52 slide along the tapered edges 50 and re-engage a selected juncture of the tapered portions 50 land the abutment portions 511.
- the subassembly 30 away from the inlet opening i12 the subassembly is rst manually pushed toward the inlet opening 12. until the hanger -arms 32 are clear of the bracket members 49.
- the primary air passage opening defined by the cylindrical portion 20 and the annular lip 35 is angularly positioned to face outwardly from the diffuseraxis and to- 'ward the panel in which the diffuser is installed, and consequently, the ⁇ air is discharged from the passageway 37 with ya velocity having a large Vector component parallel with the panel surface or in a horizontal plane when arcano? the diffuser is installed within a ceiling panel.
- This discharge of air in a direction away from the diffuser axis has the effect of drawing the secondary air discharged Ifrom the passage 4S away from diffuser axis.
- the primary air discharge opening is turned inwardly zwith the result that the discharge of the air from the passage 37 is adjustable between the aforementioned direction avv-ary from the diffuser aids and a direction toward the diffuse-r axis, and las the direction of discharge of the primary air is turned inwardly, it will impose an inward iiow upon the secondary yair discharged from the passage 4S.
- the air diduser of this invention provides a simple construction which may be economically fabricated and which incorporates means for varying the direction of flow of the discharged air. Additionally, this air diffuser can be readily assembled within an opening in a ceiling panel or the like and provides an aesthetic and ornamental appearance without hindering or obstructing the air flow therethrough.
