Definitions
- Another object of the present invention is to afford a novel air diffuser which is particularly well adapted for use as a ceilingair diffuser.
- Ceiling air diffusers have, of course, been heretofore known in the art.
- ceiling ,air diffusers heretofore known in the art have had severalinherent disadvantages, such as, for example, discharging airat undesirable vertical angles, such as, too directly downwardly; not being well adapted for use in various parts of a room; or notbeing adjustable for controlling the amount or direction of the discharge of air therefrom, and the like. It is an important object of the present invention to overcome such disadvantages.
- Another objectof the present invention is to afford a novel ceiling air diffuser which is well adapted for installation and usein any part of a room.
- Anotherobject is to afford a ceiling air diffuser which is constructed in a novel and expeditious manner whereby, when it is being used in the'central portion of a room, it may. be adjusted'to discharge air in all horizontal directions, and when it is being used at one side ,of a room, such as, for example, adjacent to a wall or in a corner, or the like, it may be quickly and easily adjusted toprevent air being discharged therefrom in the direction of the immediately adjacent wall surface.
- Yet another object of the present invention is to afford a novel ceiling air diffuser, wherein the velocity of the discharge of air therefrom in any direction may be selectively adjusted.
- a further object of the present invention is to afford a novel ceiling air diffuser which is practical and efficient in operation and which may be readily and economically produced commercially.
- FIGS. 1-4 oft he drawings to illustrate the presently preferred embodiment of the present invention.
- I v f The air diffuser 1 is particularly welladapted for use as a ceiling air diffuser, and embodies, in general.
- upper air inlet 2 for feeding air downwardly into an air chamber 3 defined by a body portion 4, for discharge substantially horizontally outwardly therefrom through a discharge passageway 5 formed in the outer peripheral edge portion of the body portion 4, FIG. 2, as will be discussed in greater" detail presently.
- the air diffuser l embodies an upper, or top plate 6,
- the plate 6 111- cludes a substantially flat, square-shaped, annular, intermediate peripheral edge portion 7, from the outer edge of which a square-shaped, annular,-outer peripheral edge portion 8 projects upwardly and outwardly, and from the inner edge portion of which an inner peripheral edge portion 9 projects upwardly and in-' wardly, FIG. 2, the inner peripheral edge portion 9 having a square-shaped outer peripheral edge.
- Asubstantially round, cylindrical or annular collar 10 is attached to the innerv edge of the inner peripheral edge portion 9, ancl projects substantially'vertically upwardly there from to afford the aforementioned inlet 2.
- the air diffuser 1 also includes a substantially square second plate 11, the main bodyportion 12 of which is substantially flat, and is disposed in downwardly spaced parallel relation to the intermediate edge portion 7 'of the upper plate 6.
- a substantially cup-shaped central portion 13 projects downwardlyfrom' the center of the body portion 12 and terminates in a substantiallyflat bottom wall 14, which is disposed in parallel relation to the body portion 12,'FIG.'2.
- a plurality of vanes 15 extend between the intermediate peripheral edge portion 7 of the plate 6'and the outer peripheral edge portion of the plate 11, and are rotatably mounted therein for a purpose which will be t discussed in greater detail hereinafter.
- Each of the vanes 15 issubstantially flat, and embodies a substantially rectangular-shaped 'blade or body portion 16, having oppositely disposed ends 17 and 18 and oppositely di'sposed longitudinal side edges 19 and 20.
- Each of the vanes 15 has two portions 21 and 22, which are reduced in size and project outwardly from the mid portions of the end portions 17 and 18, respectively, to afford pivot members for rotatably mounting the vanes 15 in the body portion 4 of the air diffuser l.
- the pivot members 21 and 22 preferably are substantially flat and disposed in uniplanar relation to the respective blades 16 from which they project, and are rotatably mounted in openings 23 formed in the intermediate peripheral edge portion 7 of the plate 6 and the outer peripheral edge portion of the plate 11, respectively.
- the pivot members 21 and 22 preferably are mounted in the respective openings 23 with a relatively snug, but freely rotatable fit, so as to prevent vanes 15 from vibrating horizontally relative to the plates 6 and 11. Also, the
- vanes 15 are effective to hold the plates 6 and 11 in assembled relation to each other, the vanes 15 being secured against withdraw] from the openings 23 by suitable means such as peening the outwardly projecting extremities 21a and 22a of the pivot members 21 and 22, respectively.
- the vanes are spaced along the sides of the square-shaped plates 6 and 11 on centers which are so spaced from each other that when adjacent blades 16, which are adjacent along one of the aforementioned sides, are disposed in uniplanar relation to each other, as shown in FIG. 4, the adjacent longitudinal edges 19 or 20 of the adjacent blades 16 are disposed in such close juxtaposition to each other that they afford an effective obstruction against the passage of air therebetween, while not being in actual abutting engagement with each other, so that each of the vanes 15 is freely rotatable around its pivot members 21, 22 without interference from the vanes disposed at the same side of the square-shaped plates 6 and 11.
- the vanes 15 may abe disposed at any angle between a fully closed position, as shown in FIG. 4, wherein the blades 16 of adjacent vanes 15 are disposed in position relative to each other effective to prevent the passage of any substantial amount of air outwardly therebetween from the air chamber 3, and a fully open position as shown in FIG. 1,.wherein the vanes 15 are so disposed that the blades 16 of each of them are disposed in substantially radially outwardly extending position relative to the longitudinal center line of the air inlet 2.
- the air diffuser 1 is particularly well adapted for use in the central portion of a ceiling of a room, the air being discharged in all horizontal directions from the outer periphery of the body portion 4.
- the vanes 15 may be disposed in an infinite number of other positions, so that the air diffuser 1 is readily adjustable for substantially any operating condition.
- the velocity of the air passing outwardly between the blades disposed at the aforementioned inwardly opening acute angles is increased, which is also effective to increase the throw, or distance of discharge, of the air horizontally outwardly from the air diffuser l.
- the air diffuser 1 shown in the drawings also embodies a bottom plate or cover plate 26, FIG. 2, which has a substantially flat central portion 27 secured to the lower face of the bottom wall 14 of the central portion 13 of the plate 11 by any suitable means such as, for example, rivets or spot welding, not shown.
- the bottom plate 26 may be of any suitable configuration, such as, for example, the substantially steppedcup-shape shown in FIG. 2, but preferably terminates at its outer edge portion in an outer peripheral edge portion 28, which is disposed in downwardly spaced substantially parallel relation to the outer peripheral edge portion 8 of the plate 6, so that the peripheral edge portions 8 and 28 define the upper and lower boundaries of the discharge 5 of the air diffuser 1.
- the vanes 15 may be disposed in the desired open position around the periphery of the body portion 4, such as, for example, the fully open position shown in FIG. 1.
- the positions of these vanes may be adjusted to any selected position between the aforementioned fully open position, shown in FIG. 1, and the aforementioned fully closed position, shown in. FIG. 4.
- This construction is particularly advantageous when the air diffuser 1 is to be disposed adjacent to a wall, or adjacent to two-walls such as, for example, in a corner. of a room. Under such conditions, the vanes 15 in the side of the air diffuser disposed adjacent to such a wall may be disposed in the aforementioned fully closed position, as shown in FIG. 4, so as to close off the discharge of air outwardly from that side of the air diffuser.
- the vanes 15 of the air diffuser I afford control members for selectively preventing or pennitting the discharge of air from selected portions thereof; controlling the direction of the discharge of air therefrom; and controlling the velocity of the discharge of air therefrom.
- the present invention affords a novel ceiling air diffuser which is practical and efficient in operation and which may be readily and economically produced commercially.
- said second plate and said outer peripheral edge portion of said third plate defining the opposite side of said discharge passageway
- vanes mounted in said discharge passageway for controlling the flow of air therethrough
- said vanes each comprising 1. substantially flat blades having a. oppositely disposed ends, and b. two oppositely disposed edges extending between said ends, and 2. two reduced end portions projecting outwardly from substantially the midpoint of respectives ones of said ends to afford pivot members,
- vanes being disposed between said first mentioned and said second plates-with 1.
- said pivot members on one end of said blades being rotatably mounted in said first mentioned peripheral edge portionof said first mentioned plate, and
- said pivot members on the other end of said blades being rotatably mounted in the outer peripheral edge portion of said second plate forrotation of said vanes through 360 around the longitudinal center lines of the pivot members thereon, and
