Cl. 9s 40 7 Claims Int. Cl. F24f 7/00, 13/08; 1104b /54 The present invention relates to ventilating ceiling constructions, more particularly of the type in which the space between the main ceiling and a suspended ceiling, below the main ceiling is a substantially air-tight plenum, through which air may be introduced to the room by Way of novel ventilating elements, which are substantially in overlapping relation with the edges of one or two adjacent edges of successive panels of the suspended ceiling.
The term panel as used in the claims is generic to the elements of a suspended ceiling whether rectangular or square, commonly called a panel or tile respectively.
It is among the objects of the invention to provide a relatively simple ventilating ceiling construction of relatively low cost in which standard panel or tile construction and suspension members therefore may be used with but a relatively simple and inexpensive modification of the panel or tile for flow of air through the suspended ceiling.
Among other objects are to provide a ventilating ceiling construction of the above type in which the ventilating structure by which air is propelled from the plenum to the room or conversely is carried by one panel or between neighboring panels and is readily adjustable to control at will the degree of ventilation or air flow between those edges of any pair of neighboring panels that extend longitudinally thereof and are parallel to the panel carrying members.
It is a feature of the invention to provide a series of spaced air-ports or apertures through the thickness of each panel adjacent one edge thereof, which may be notches in the edge of the panel and to associate therewith and adjustable slider which may be of metal or plastic and which has notches or orifices therein distributed longitudinally thereof, corresponding to the notches or apertures in the panel and with intervening closure portions of width greater than the Width of the notches or apertures in the panel, whereby the slidable adjustment of the slider will serve wholly to close the notches or apertures in the panel or partly or completely to open them, as desired for desired ventilation.
In the accompanying drawings in which are shown one or more of various possible embodiments of the several features of the invention FIG. 1 is an exploded perspective view of one embodiment of the invention viewed from above;
FIG. 2 is a fragmentary detail perspective view on an enlarged scale of one of the tiles or panels viewed from above;
FIG. 3 is a perspective view with parts broken away of a vent control slider;
FIG. 4 is a view in cross-section showing the assembly of the slider with respect to the panel;
FIG. 5 is a perspective view of another embodiment of panel;
FIG. 6 is a perspective view of the corresponding control slider;
FIG. 7 is a view in cross-section of the assembly of panel and control slider of FIGS. 5 and 6;
FIG. 8 is a top plan view of another embodiment, looking down at the suspended ceiling, of ceiling tile arrangement;
3,429,25d Patented Feb. 25, 1969 FIG. 9 is a plan view of the slider used with the embodiment of FIG. 8;
FIG. 10 is a plan view looking up at the suspended ceiling, showing the slider of FIG. 9 in position;
FIG. 11 is a detail sectional view on an enlarged scale taken along line 1111 of FIG. 10;
FIG. 12 is a view similar to FIG. 11 taken along line 1212 of FIG. 10;
FIG. 13 is a view similar to FIG. 11 taken along line 13-43 of FIG. 10;
FIG. 14 is a view similar to FIG. 11 taken along line 14-14 of FIG. 8; and
FIG. 15 is a fragmentary perspective view with parts broken away of one of the panels of FIG. 8.
Referring now to the embodiment of FIGS. 1 to 4, FIG. 1 shows the ceiling C broken away in large part and the suspended ceiling S therebelow with inverted T carrying members 10 extending longitudinally of the as sembly of panels or tiles, each carrying member being hung from the ceiling as by wires w. Some or preferably all of the panels 14 which may be of the usual acoustical or non-acoustical ceiling board, have notches 15 in spaced relation, illustratively equally spaced at least along one edge thereof, which notches extend through the entire thickness of the panel. Between consecutive notches 15 the panel presents lands 16 which are desirably wider than the notches.
It will be understood that instead of notches there may be apertures corresponding to the innermost portions of the depth of the notches, and these spaced slightly from the edge of the panel.
Associated with each notched edge, or the like of the panel is a ventilating adjustment slider 17 which may be of any desired rigid material such as sheet metal or plastic. The slider which illustratively is substantially U-shape, is desirably of length slightly less than that of the associated panel. It presents an upright Wall 18 of height but slightly greater than the thickness of the panel. The slider presents a lower horizontal wing 19 upon which the edge of the panel rests, as shown in FIG. 4, which wing 19 is of width somewhat less than the depth of the notch 15. The panel also presents an upper Wing 21 parallel to Wing 19 overlying the edge of the panel 14. The slider has notches 22 in its upper wing 21 of Width preferably slightly greater than that of the notches 15 in the panel. The lands 23 between successive notches 22 in the slider 17 are of width considerably greater than the width of the notches.
The slider in the embodiment shown in FIGS 1 to 4 and herein described, encloses the edge portion of the corresponding panel, with upright wall 18 engaging the end portion 24 of the panel at the notched edge, the wing 21 overlying the panel and being of width to cover the entire depth of the panel notches and to cover the apertures if these are used instead of notches, and the lower wing 19 underlying the edge portion of the panel.
In order to combat leakage of air from the plenum, between the slider 17 and the supporting member 10, the slider is desirably equipped with a fin 25 secured to the Wing 21 and protruding slightly therebeyond and engaging the vertical wall 26 of member 10 as shown in FIG. 4. The fin 25 may be an integral part of the wing 21 or it may be a flexible member adhesively attached along the entire length thereof.
In addition, since the free ends 27 of lands 23 extend past the inner ends of the notches 15 and rest on the panel as shown in FIG. 4, leakage is minimized when the slider 17 is moved to close the notches 15.
In the embodiment of FIGS. 5 to 7, the panel 14 is substantially the same as that of FIGS. 1 to 4 except that the edge of the panel 14', notched as at 15, also has a longitudinal kerf 28 extending the length thereof, across 3 the width, preferably of each of the lands 16' and desirably midway of the thickness of the panel 14'.
The control slider 17' in this embodiment is substantially the same as control slider 17 except that its upright wall 18 is of height substantially equal to one-half the thickness of panel 14.
The distance between the wings 19' and 21 of the control slider 17 is such that when the wing 19' fits into the kerf 28, the wing 21' will rest on the top surfaces of the panel as shown in FIG. 7.
The adjustment in the embodiment of FIGS. 1 to 4 and 5 to 7 may readily be effected by lifting the panel olf the supporting member and then moving the control sliders 17, 17 t the desired position.
In the embodment of FIGS. 8 to 15, the adjacent longitudinal edges 31 of contiguous standard kerfed and cutback panels 32 are in edge to edge engagement with each other, as shown in FIG. 13. These adjacent edges 31 have registering notches 33 desirably quite narrow, illustratively but inch in depth, so that the combined width of two registering notches of contiguous panels is 2 inch or thereabouts. The length of these notches may be as desired.
The adjustable vent control slider 34 (FIG. 9) in this embodiment is desirably a metal, plastic or fiber plate, illustratively about inch wide, which has one or more longitudinal slots 35 therein along its length midway of its width, desirably wider than the combined widths of the registering notches 33 in contiguous panels 32, each slot being of length somewhat greater than the length of the notches 33 in the edges of contiguous panels.
The slider plate 34 lies in the kerfs 36, one-half in the kerf 36 in the panel 32 to the left of the slider and the other half in the kerf 36 in the panel to the right of the slider, as shown in FIG. 12, for example. Depending upon the adjustment of the slider plate 34, by means of a tool inserted in the opening 37 at the end of the plate 34, the plate may be moved and the air vent determined by the registering slot 35 and notches 33 may be closed, widely opened, or partially opened to the extent desired for controlling the flow of air from the plenum to the room or conversely as the case may be.
The panels 32 may be suspended as shown in FIG. 14 by merely inserting the Wings 38 of the supporting member 39 in the kerf portion 41 at the side edge 42. of the panels.
It will thus be seen that the present invention in its various embodiments is concerned with a ventilating ceiling of simpler and less costly construction than that of my prior application Ser. No. 76,711, filed Dec. 19, 1960, now lPatent No. 3,103,868, issued Sept. 17, 1963 and of adequate effectiveness for many purposes.
As many changes could be made in the above constructions, and many apparently widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
