SLIP SPLINE SUSPENDED CEILING STRUCTURE Filed April 21. 1964 INVENTOR. BRUCE W KID/V57 @fm Mu A 7mm/EVS United States Patent Olhce 3,381,437 Patented May 7, 1968 3,381,437 SLIP SPLINE SUlaPENDED CEIUNG STRUCTURE Bruce W. Kidney, 57 Montague St., Brooklyn, NX. 1120i Filed Apr. 21, 1964, Ser.. No. 361,428 3 Claims. (Cl. 52--497) This invention relates to ceilings formed of acoustic or other tile, and in particular to a new and improved tile assembly.
Acoustic tile used in forming a ceiling may, in many instances, need to be removed at one particular point to obtain access to junction boxes, valves, cutoiis, elements of the Ventilating system, and the like. In the past, it has been necessary to either destroy elements of the tile to obtain such access or to have the tile supported in such a manner that the supporting units are visible to the observer below. Neither method is completely satisfactory. Other systems may be so put together that any tampering with the ceiling results in extensive damage to the appearance.
The present invention has the advantage that it provides for a tile ceiling which may be readily and inexpensively assembled without the utilization of special tools. The resulting -ceiling is durable and strong, and the tile supporting elements are not visible.
The assembly has the further advantage that any one or more tiles in the entire assembly may be readily removed Without use of special tools for access to the area above, and may, thereafter, just as readily be replaced.
The assembly of this invention may be made with but slight modications of existing structures and at a decided cost advantage.
In the practice of my invention, tile is used having longitudinal slits or kerfs in two opposing edges of the tile. These kerfs are of the type that have in the past been used on edges of the tile to t over the horizontal flange or web extending along the bottom edge portion of a C-bar or Z-bar or a standard concealed spline. An example of such a structure is found in Lydard Patent No. 2,866,233. The assembly of my invention also includes a series of parallel, horizontal C-bars, spaced apart a distance approximating the tace dimension of the tile. Below and contiguous with the lower tiange portions of the Cebars are tted slip splines made or" resilient metal and having a base portion from the longitudinal edges of which extend gripping jaws. One of the jaws overlies the flange and the other presses against the vertical web of the C-bar to hold the spline in place. The jaws are of about the same width and overlie substantially the entire base portion. The splines are of length less than the length of the tile, along the C-beam, and preferably of a length substantially less than half the length of the tiles.
The splines tit within keris of tiles on each side of the C-bar to hold the tiles in place. A spline may be removed, however, by sliding it horizontally along the C-bar until it is no longer positioned within the kerf of the tile to be removed.
The above and other advantages and details of the invention will 'be seen from the appended drawings, in which:
FIG. 1 is a view from below of a portion of a tile assembly supported in the manner of the present invention;
FIG. 2 is a section taken along the lines 22 of FIG. l, showing a cross section of a C-bar with the slip spline thereon, and edge portions of two adjacent tiles supported by the spline;
FIG. 3 is an exploded partial perspective view showing a typical portion of 4a joint such as the joint of FIG. 2; and
FIG. 4 is a perspective of a slip spline of the type used in my invention.
There have been, in the past, numerous acoustical tile ceiling structures utilizing horizontal `C-bars or ZJbarS. Examples of these are found in Urbain Patent No. 2,340,- 911, Jacobson Patent No. 2,648,102, and Carlson Patent No. 3,160,3' 19. ln FIG. l of the appended drawings there is shown utilization of the same basic C-bar construction together with the improvement oi my invention.
Thus, in FIG. l there are present C-bars 1, 2 and 3. These support a group of acoustical tiles indicated generally by the numeral 5 and include, for example, tiles 6 and '7. The C-bars are spaced apart a distance substantially equal to the width of the tiles in question. lt will be seen that C-bars 1 and 2 are spaced apart approximately the width of tile 7, and C-bars 2 and 3 are spaced apart approximately the width of tile 6.
Shown in dotted outline in FIG. 1 are the various slip splines used in my invention, as, for example, spline 1i).
In the preferred form of my invention there will be four splines in their respective kerfs to support each tile, but each spline will be used to support a corner of two dilferent tiles. Thus, tile 6 is supported by splines 10, l1, 12, and 13; but splines lil and lll also support tile 7, and splines l2 and 13 also support the tile 15 to the right of tile d, as viewed in FlG. l. Comparable splines 1l and l2 also support corners of tile 5; and splines 1i) and 13 support corners of tile 8.
lt is preferable that the total length of all the splines along one edge of a tile be of less length than approximately two-thirds the width of that tile.
FIG. 2 shows a section along lines 2 2 of FIG. l. There there will be seen the C-bar 2. C-bar 2 is formed of vertical arm or web 20, the upper supporting portion 2l, and the base ange 22. Supporting portion 2l is secured to the upper ceiling of other cross members in the usual manner (not shown in the drawings), and supports C-bar 2 is a position with its axis running horizontally. Base flange 22 is normally at right angles to vertical support 20 and is a thin metallic section of the type often adapted to lit within the kerf of an acoustic tile.
As is shown in FIG. 2, each of the tiles, here represented by tiles d and 7, has along its edges a slit or kerf. Thus, along the edge of tile 7 adjacent to C-bar 2 there is kerl 2S, and along the edge of tile 6 that is adjacent to Cbar 2 is kerl 26, Since these kerfs are formed within the edges, they 4are not visible when the tile is installed.
`Spline ill includes a longitudinal base 30 folded about at opposing longitudinal edges to form gripping jaws. One jaw is the locking member 31, and the other is the supporting open member 32. Supporting member 32 overlies ilange 22 when in use, and the locking member has a locking edge 42 and presses against the vertical web 2l) to secure the spline in position. There is a. gap 38 between the edges of supporting member 32 and longitudinal member 3d. This gap preferably is of a width. at least approximating the thickness oi the flange 22 of C-bar 2. Thus, in cross-section, spline lt) has an appearance somewhat resembling an almost closed staple of the type normally used for stapling papers together.
As shown in FlG. 3, locking member 31 may, if desired, have beveled edge portions 35 and 36 for ease of installation.
In the completed assembly, spline lll is positioned about flange 21E-with the supporting member, or gripping jaw, 31 located above ange 22. The base 3i] below flange 22 and the Iremainder of base Sil extend in a horizontal direction toward the opposite side of vertical support 20. The width of the spline on each side of supporting arm 20 is slightly less than the depth of the kerfs 25 and 26, but, of course, is sufficient to surround base portion 22 of C-bar 2. Thus, when the kerfs 25 and 26 of tiles 7 and 6, respectively, are fitted over the spline 10, the spline will serve to hold the tile in position, and keep the face of the tile level.
The spline is preferably made of galvanized sheet steel, though other metals or plastics may be used. The material from which the spline is made should have sufficient structural strength to support the tiles in their installed position, and at least some flexibility for installation and locking as will be described below. The spline is preferably dimensioned with all of the supporting member lying to one side of its longitudinal mid-point axis and all of the locking member lying on the other side. Locking edge 42 is positioned to hold the unit with the axis below web 2li. The pocket formed by base portion 3@ and supporting member 32 should be of width equal to the width of flange 22.
Further details of the assembly of the ceiling unit and of the structure of the slip spline are shown in FIGS. 3 and 4, which have numbers corresponding to those in FIGS. 1 and 2.
In constructing a ceiling using the assembly of my invention, the C-bars are installed in the usual manner, spaced, as described previously, a distance equal to the width of thetiles. The slip splines are then slipped over the edge 40 of flange 22 of each of the C-bars. This is accomplished by pressing edge 32 of the slip spline onto flange 22 so that flange 22 enters gap 38 (between supporting member 32 and base 30). The pressure is continued until the inner edge 42 of locking member 3l has passed by the vertical support 2.0. Due to the flexibility of the metal from which the spline is made, this spline will snap in place, being retained by the edge locking member 31 pressing against the lower portion of vertical support 20.
As referred to previously, there will be C-bars along each opposing edge of given tile. Thus, in installing the tile, the slip splines will be snapped on C-bar and slipped into place as needed. For example, kerf 25, of tile 6 is inserted about flange 22 of the C-bar. Then tile 6 is lifted into position on C-bar 2, slip spline 10 is snapped on C- bar 2 and slipped longitudinally half the length of the slip spline into kerf 26, thus supporting tile 6, then slip spline 11, is snapped onto C-bar 2 and slipped totally into kerf 26, tile 6. Kerf 25 of tile 5 is then inserted on flange 22 of C-bar 1. Tile 5 is then lifted into position on C-bar 2. Slip spline 11 is slipped longitudinally along C- bar 2 to overlay tile 6 and 5, thus supporting the tiles.
It will be seen that in their supported position, the tiles block from view the flange 22 of the C-bar and the splines themselves.
As the installation of tile proceeds and the splines become covered, it may be necessary to move some of the splines that are already covered and cannot be reached with ones hands, or to move splines into positions where they cannot be reached. This is readily accomplished by the insertion of a knife blade between the tiles, and by pressing the knife blade against the end of the spline to slide it axially along the C-bar. Thus, as the ceiling is completed the splines may be slid into place and retain the tiles in position.
When at a later date it is necessary to obtain access to the area above the acoustic tile, this can readily be done by inserting a knife blade in the space between two tiles, and using the edge of the blade to slide the supporting splines to one side. The tile is then released and may be removed. It can, of course, later be replaced by fitting it into position and again sliding the splines into a supporting position. As can be seen, no damage has been done by obtaining temporary access to the area above the tiles, and access has been had readily without the use of any special tools. The structure in question is strong and secure and supports the tile without the supporting structures showing.
The present invention is not limited strictly to the embodiment disclosed, but encompasses modifications thereof falling within the appended claims.
