The invention relates generally to ventilating apparatus and more particularly to a ventilating apparatus of the type including a ceiling structure having a frame-work made up of pipes carrying a heat exchange medium and supporting a plurality of pans made of thermally conductive material and forming a continuous radiant ceiling surface, the pans cooperating with suitable cover means to form a plenum chamber adjacent the continuous ceiling surface and also carrying valve controlled means to admit a supply of temperature conditioned ventilating air from a source of higher pressure into the plenum chamber for diffusion outwardly through a foraminous portion of the pan.
According to the general features of the present invention, a ceiling ventilating apparatus comprising a plurality of spaced pipes arranged in coplanar relationship forms a ceiling framework. A pan having a foraminous surface is extended between each pair of adjacent pipes and includes upstanding flanges shaped to clip on to the pipes. When a plurality of pans are thus assembled, a continuous radiant ceiling surface is provided since the pans are made of thermally conductive material and the temperature of the pans is controlled by conducting a heat exchange medium through the pipes.
A duct to carry a supply of temperature conditioned ventilating air at increased pressures is located superadjacent the pipes and is provided with a duct outlet. Wall means cooperate with the pans to form a plenum chamber and a suitable inlet aperture is provided for the plenum chamber. A flexible sleeve is located be tween the duct outlet and the inlet aperture of the plenum chamber and adjustable valve means are provided in the inlet aperture to control the admission of air at higher pressure into the plenum chamber for diffused distribution outwardly through the foraminous portion of the pan.
It is an object of the present invention to provide a combination ventilating apparatus which will effect the simultaneous distribution of radiant heat and temperature conditioned ventilating air.
Another object of the present invention is to provide an improved ceiling ventilating apparatus.
A further object of the present invention is to provide an air distributing apparatus which is concealed behind and forms a part of a continuous radiant ceiling surface.
Another object of the present invention is to provide an irnproved ventilating apparatus operable on the so called pressure-displacement principle.

Figure 2 is a fragmentary side elevational view, with parts shown in section, of the structure of Figure 1;
Figure 3 is a plan view of the cover member provided in accordance with the principles of the present invention; and
Figure 4 is a view showing a development of the cover member of Figure 3.
As shown on the drawings:
A particularly useful application of the principles of the present invention is made in connection with the provision of a ceiling ventilating apparatus although it will be understood that the ventilating apparatus can be advantageously employed with any wall surface of an enclosure or space to be ventilated.
In the preferred embodiment shown by way of illustrative example, a plurality of spaced pipes 10 are arranged in co-planar relationship to form a ceiling framework. It will be understood that the pipes may be supplied with a heat exchange medium and, in this connection, there is indicated in Figure 2 a header 11 supplied with heat exchange medium such as hot water, steam, or in the event cooling is required, a coolant pressurized by a pump P powered by a motor M discharging through a heat exchanger HE and through a thermostatic valve V. It will, of course, be understood that instead of a plurality of separate pipes 10, a tortuously twisted pipe might be arranged to provide the ceiling framework as shown in the drawings.
A continuous ceiling surface is provided by suspending a plurality of standardized pan members 12 on the pipes 10. Each of the pan members 12 is made of a thermally conductive material and is assembled with the pipes 10 in thermally conductive relationship therewith so as to form a radiant ceiling surface which may be effectively utilized to control the distribution of radiant heat energy to the space or enclosure with which the ceiling surface is associated.
In accordance with the principles of the present invention, a ceiling structure thus provided is modified to develop the additional function of distributing temperature condition ventilating air at the same time.
Referring specifically to Figure 1, is will be noted that each of the pans 12 extends between a pair of adjacent pipes 10 and includes a first wall portion 13 having a plurality of perforations 14 extending therethrough to render the wall portion 13 foraminous. At opposite margins of the wall portion 13 an upstanding flange 16 and an upstanding flange 17 are provided, each of the flanges 16 and 17 providing side walls for the pan 12 with an arcuately-shaped clip portion 18 and 19, respectively.
The arcuately-shaped clip portions 18 and 19 are, in effect, of C configuration and it will be noted that both open in the same direction so that a pan member 12 may be moved in general registry with a pair of the pipes 10 and is then laterally displaced until clip portion 18 engages the clip portion 19 of the next adjacent pan member 12 and the clip portion 19 engages the corre- Each cover member 20 is made from a flat sheet of metal shaped as shown in Figure 4 and includes a plate Reissued Apr. 21, 1959 portion21- having an inletaperture 22 form in a central portion thereof and bounded on its margins by offset flanges 25 which are bent downwardly at an acute angle to the plate portion 21 along the bend lines 23.
Each of the corners of the'cover member 20 are notched as at 24 to facilitate abutment of the longitudinal andtransverse flanges 25. A retainer member 26 is spot welded to each of the corners after the cover member 20 is formed into proper shape to retain the flanges 22 in locked. assembly.
Adjacent each corner of the plate portion 21 of the cover member 20 is provided a pair of apertures 27. On one. margin of the plate portion 21, a pair of retainer clips 28 are firmly assembled to the cover member 20' by means of a plurality of rivets 29. Each of the retainer clips 28 comprises a. strip which is arcuately shaped as at 30 so as to underlie a part of the clip portion 18 on the flange 16 of the pan member 12.
On the opposite margin, 21 pair of clip members 31 are pivoted to the plate portion 21 of the cover member 20 by means of rivets 32. Each of the clip members31 comprises a strip which is arcuately shaped as at 33 and which may be pivoted into position so as to. abuttingly' underlie a portion of the corresponding pipe after which each of the clips 31 may be placed in firm assembly with the plate portion 21 of the cover member by threading a screw 34 through the corresponding clip member 31 into one of the apertures 27.
The cover member 20. is received by the pan member 12 with the. flanges engaging the wall portion 13, thereby spacing the plate 21 relative to the wall portion 13 and forming with the pan member 12 a plenum chamber 36.
A collar 37 flanged as at 38 is spot welded to the plate portion 21 of the cover member 20 and provides an upstanding, flange 39 forming a throat for the inlet aperture. 22.
A bracket 40 spans the throat or flange 39 and is spot Welded thereto in firm assembly therewith. The bracket 40 carries a nut 41 which threadedly receives a bolt 42 having an adjusting head 43 to facilitate turning of the bolt 42, thereby to axially position the bolt relative to the nut 41 and the bracket 40.
The bolt 42 extends into the plenum chamber 36 and carries on the end thereof a valve plate 44 carried by a retainer 46 received on the end of the bolt 42.
As is shown in Figure 3, the valve plate 44 has substantially the same configuration as the inlet aperture 22 and selective adjustment thereof relative to the throat provided by the flange 39 of the collar 37 will operate to control the admission of air into the plenum chamber 36.
A duct 47 is provided superjacent the ceiling framework provided by the pipes 10 and carries a supply of pressurized temperature conditioned ventilating air. In other words, the duct 47 may be considered as forming a primary plenum chamber 48. A duct outlet 49 is provid'ed and a collar 50 is fastened to the duct 47 by a plurality of fasteners 51, thereby to provide a flange 52 at the duct outlet 49.
It will be understood that theduct 47 and the plenum chamber 36 are relatively spaced from one another. Thus, in order to supply air from the primary plenum chamber 48 to the plenum chamber 36, a generally tubular flexible sleeve 53 is clamped to the flange 52 by means of'a clamp retainer 54 and the other end of the sleeve 53 is clamped to the flange 39' by means of a clamp retainer 56.
The sleeve 53 preferably comprises a flexible material which is somewhat rigidified by means of a coil spring 57-. It will be appreciated that in a typical architectural' installation the duct works for the primary ventilating system such as the duct 47 will be installed prior to the suspension of the ceiling surface aflorded by the: wallportions 13 of the pan members 12, hence, the use of the present invention affords a Widev range of tolerance in locating the duct outlets 49 and the inlets 22 for each of the plenum chambers 36. In other words, there. is
an air distributor at the free end of each sleeve 53. The air distributor is formed by the pan and cover members 12 and 20. The upper wall means of the air distributor comprises the inlet-forming portion connected to the flexible sleeve 0r conduit 53 to receive air from the supply duct 47 and the lower wall means of the air distributor comprises the Outlet-forming portion through which air is discharged or diffused into the space being ventilated. Since the upper and lower wall means of the air distributor are j0ined,.all air from the conduit or sleeve 53 is confined and directed through the finished surface of the inner wall and into the space. In reference. to an entire ceiling surface, it will be further ap-- preciated that a plurality of plenum chambers 36 may be located at spaced intervals so that a supply of temperature conditioned ventilating air may be diffused through corresponding portions of the ceiling surface simultaneously with. the distribution of radiant heat to the space being ventilated by virtue of the fact that the. continuous ceiling surface is radiant in character.
