The invention relates generally to ceiling tiles, and more specifically to ceiling tiles with insertable baffles.
Grid-based drop ceilings are ubiquitous in commercial and some residential spaces. These types of ceilings use tiles placed in a suspended grid to conceal mechanical structure in the ceiling, such as ductwork, as well as to dampen noise in the space below.
U.S. Pat. Nos. 10,975,568 and 11,174,635 disclose ceiling tiles for grid-based drop ceilings. The ceiling tiles of these patents have hanging baffles that serve to improve noise reduction while retaining the useful features of grid-based tiles. Many of the tiles disclosed by these patents are made in a single piece—a sheet of tile material folds from a flat configuration into a three-dimensional configuration that includes a tile portion that rests in the grid as well as the baffle. However, U.S. Pat. No. 10,975,568 does disclose an embodiment of a baffle-tile in which the baffle is a separate piece that inserts into a slot in the main body of the tile. In this separate-baffle tile, the baffle has a thickened top portion that prevents it from falling through the tile.
While the separate-baffle tile of U.S. Pat. No. 10,975,568 is useful, its thickened top portion may pose issues at multiple points in the product lifecycle. During manufacture, the thickened top portion may require the use of fasteners or adhesive, which complicates the manufacturing process. When the tile is disposed of at the end of its lifecycle, the presence of adhesives or fasteners may make it difficult to recycle the material.
One aspect of the invention relates to a ceiling tile. The ceiling tile includes a tile, a baffle, and a locking member. The tile has a slot through its thickness. The baffle has a body sized and adapted to insert through the slot in the tile. A pair of flaps are defined in the baffle by fold lines and are adapted to fold outwardly, away from the body of the baffle. The flaps also have a locking slot that is defined in or by them. The locking member is complementary to the slot and can be inserted into it to lock the pair of flaps into place.
In one embodiment according to this aspect of the invention, the baffle may be made of a single sheet of material, in which case, the body may comprise two thicknesses of material folded against one another about a central fold line in the sheet of material. In many embodiments, the tile, the baffle, and the locking member may be made of the same type and thickness of material, such as a polyethylene terephthalate felt. With this arrangement, all of the parts can be cut from sheets of tile material.
In embodiments according to these aspects of the invention, a tile may have several slots for baffles, so that several baffles can be installed in a single tile. In these embodiments, the slots for the baffles may be arranged in various ways: offset symmetrically from the centerline of the tile, horizontally staggered, or positioned at angles to one another.
In other embodiments, the body of the baffle may fold such that it has open sides. For example, the body of the baffle may fold to take the shape of a rectangular prism, a trapezoidal prism, etc. In these cases, instead of a single locking member, a pair of locking members may be used. Each of these locking members may have a first portion that engages the slot as described above and a second portion sized and adapted to fold down to close one of the open sides of the body of the baffle. A predefined fold line allows the second portion of the locking member to fold relative to the first portion.
Another aspect of the invention relates to a method of assembling a ceiling tile with a baffle. The method comprises inserting the body of a baffle through a slot in the tile. The baffle includes a pair of flaps, and once the baffle is inserted through the slot, the pair of flaps are folded down, against the upper surface of the tile. The pair of flaps define a slot, and when they are folded down, a locking member is inserted into the slot to lock the pair of flaps into place. The locking member may have alignment features, and the locking slot into which it inserts may have complementary features.
Other aspects, features, and advantages of the invention will be set forth in the following description.
The invention will be described with respect to the following drawing figures, in which like numerals represent like features throughout the description, and in which:
More specifically, as can be seen in
Toward their proximal edges, where they meet, the two foldable flaps 18, 20 are shaped and cut in such a way that they define a slot 24 with specific features, including a transverse extent or cross 26 at each end, as well as an elongate, straight section 28 between the ends. The locking member 22 has features that are complementary to those of the slot 24. The precise features of the locking member 22 and the slot 24 may vary from embodiment to embodiment, and are not critical so long as they are complementary such that the insertion of the locking member 22 into the slot 24 forces the foldable flaps 18, 20 into the position shown in
The flaps 18, 20 are longer than they are wide. The long ends 30 of the flaps 18, 20 are beveled, as are the long ends 32 of the locking member 22.
As shown in
The arrangement shown in
In most modern installations, ceiling tiles are made of a polyethylene terephthalate (PET) felt, typically with at least some recycled content. The tile 12 and the baffle 14 may be made with PET felt, or with any other material that is commonly used to make ceiling tiles. References to “tile material” in this description should be construed to refer to any material of which a ceiling tile may be made, although many embodiments will be made of PET felt.
Of course, the tile 12 and baffle 14 need not be made of any standard ceiling tile material, although it is helpful if they are light enough to be properly supported by a drop-ceiling grid. Because the tile 12 and baffle 14 are separate, it is also possible for the tile 12 and the baffle 14 to be made of different materials from one another. For example, the baffle 14 could be made of a material that is more dissipative of acoustical energy, more dissipative of acoustical energy in particular frequency ranges, etc. Beyond functional reasons for making the tile 12 and the baffle 14 of different materials, the baffle 14 may also be made of a different material for architectural or aesthetic reasons. For example, if the baffle 14 and tile 12 are made of the same type of material, the baffle 14 may be made of a different color of material than the tile 12.
Additionally, although the configuration of the baffle 14 shown in
In this embodiment, the baffle 14 is driven straight into the slot 16. The slot 16 typically has a size and shape complementary to the size and shape of the folded body 15 of the baffle 14. In some embodiments, the slot 16 may have a width just wider than the width of the body 15 of the baffle 14, such that when the baffle 14 is inserted into the slot 16, there is a tight, frictional fit that helps to retain the baffle 14 in the slot 16.
As was described briefly above, the locking member 22 inserts into the slot 24. The slot 24 is defined by the shape of the foldable flaps 18, 20 and by specific features 40 cut into the foldable flaps 18, 20. Essentially, the presence of the locking member 22 forces the flaps 18, 20 to remain apart and folded down against the upper surface of the tile 12.
In the illustrated embodiment, the locking member 22 has a long, central portion 42 with a cross-piece 44 at each end, corresponding to the elongate, straight section 28 and the transverse extents or crosses 26 of the slot 24 into which the locking member 22 inserts. In this embodiment, the locking member 22 is made of tile material, and would typically be made of the same material, and the same thickness of material, as the tile 12 and baffle 14, although other materials could be used. Thus, when pressed into the slot 24 defined by the two flaps 18, 20, the locking member 22 lies flat, even with the thickness of the flaps 18, 20.
Normally, once installed, ceiling tiles like the baffle tile 10 are not disassembled. However, if disassembly is a concern, the locking member 22 could be made of thicker material, so that it is easier to grab and pull out of the slot 24.
During the insertion of the locking member 22, the cross-pieces 44 of the locking member 22 and the corresponding transverse extents or crosses 26 of the slot 24 are, in part, alignment features—they may help an installer to align the locking member 22 with the slot 24 for proper installation. However, as those of skill in the art will note, cross-pieces 44 are not necessary in all embodiments. In other embodiments, for example, an elongate, rectangular strip of tile material could serve as a locking member, and a tight, frictional fit between that simple locking member and its slot could prevent it from shifting once placed. Of course, other shapes for the locking member 22 are also possible and may be used. In other embodiments, the slot for the locking member may simply be defined between the respective foldable flaps 18, 20, rather than being partially cut into the foldable flaps 18, 20.
As those of skill in the art will note, the arrangement of the baffle tile 10, and particularly the configuration of the baffle 14, the locking member 22, and its complementary slot, make it possible to assemble the baffle tile 10 without the use of fasteners or adhesives. Rather, the assembly of the baffle tile 10 involves a change in the configuration and position of the foldable flaps 18, 20 of the baffle 14. With the weight of the body 15 of the baffle 14 distributed over the area of the foldable flaps 18, 20, the final assembled configuration of the baffle tile 10 shown in
Although the baffle tile 10 does not require adhesives or fasteners to remain in a stable, final configuration for installation and use, that does not preclude the use of adhesives or fasteners, particularly in special circumstances. For example, adhesives or fasteners could be used if required by local building regulations, or if the baffle tile 10 is to be installed at an angle, instead of resting on a horizontally-extending grid. Screws, staples, or other such mechanical fasteners could be applied between the foldable flaps 18, 20 and the tile 12. Adhesives could also be applied between the foldable flaps 18, 20 and the upper surface of the tile 12. Alternatively, pressure-sensitive adhesive may be pre-applied in those locations, with release layers protecting the applied adhesive until it is needed.
There are no particular limitations on the number of slots 154 that may be placed in any one tile 152, although the slots 154 should not be so numerous that the tile 152 loses its mechanical integrity. The spacing of the slots 154 is also not critical, although the slots 154 will generally be placed far enough apart that the foldable flaps 18, 20 of adjacent baffles 14, 156 can each independently lie flat against the surface of the tile 152.
In the baffle tile 10, the slot 16 is centered on the tile 12. In the baffle tile 150 of
Because rectangular tiles like the tile 170 are wider, there are potentially more options for placement of slots and baffles.
In the tile 190 of
In all of the embodiments illustrated in
As with other embodiments in this description, the baffle tile 200 and its parts 202, 204 are designed to be made and shipped flat, usually for final assembly on site just prior to installation. They are typically also of sizes that allow them to be cut out of a standard sheet of tile material, e.g., a two-foot by four-foot sheet of PET felt, although that need not always be the case.
At the outer (upper) transverse ends, the two larger sections 212, 216 have flaps 218, 220, which are separated from their respective sections 212, 216 by fold lines 222, 224. The flaps 218, 220 have essentially the same features as the flaps 18, 20 described above, e.g., they are broader in at least one dimension than the slot 206 in the tile, and thus, will prevent the baffle 204 from falling through the slot 206. Yet while the flaps 218, 220 may have the same basic purpose and features of the flaps 18, 20 described above, differences in the size and proportions of the slot 206 may require the flaps 218, 220 to have significantly different proportions or dimensions than the flaps 18, 20 described above.
In addition to the features described above, the body 205 has a pair of grooves 226, 228 that run longitudinally and continuously along all three sections 212, 214, 216 and also extend continuously over the fold lines 222, 224 that separate the three sections 212, 214, 216. The grooves 226, 228 are inset a short distance from the lateral edges of the body 205. The purpose of the grooves 226, 228 will be described below in more detail.
As with the flaps 18, 20 described above, the flaps 218, 220 define a slot 230 between them. The slot 230 accommodates structures that lock the baffle 204 in place. However, because the baffle 204 is configured differently from the embodiments described above, the locking structures are different. Specifically, the baffle tile 200 uses two locking members 232, 234, both of which are shown in
The upper segments 236 serve the purpose that the locking member 22 does in the embodiments described above. Specifically, each of the upper segments 236 is complementary in shape to the shape of the slot 230, in particular having projections 240 that are complementary in shape to features 242 cut into the inner edges of the flaps 218, 220. In this embodiment, the upper segments 236 also have a beveled edge 244 that matches the corresponding beveled edges 246 of the flaps 218, 220.
The lower segments 238, by contrast, have a purely rectilinear shape. Each upper segment 236 is separated from its respective lower segment 238 by a fold line 239 that is cut into the material.
As shown in
In the description above, the baffle or baffles 14, 204 are rectangular or rectangular prisms. However, the baffle of a baffle tile may have a variety of shapes. As one additional example,
The placement of baffle tiles 10, 200, 300 need not be entirely dictated by functional considerations. In many cases, baffle tiles 10, 200, 300 may be placed for aesthetic as well as functional reasons.
In the description above, the parts of the baffle tiles 10, 200, 300 are typically made of the same type of material. While this need not be the case in all embodiments, even if the parts of baffle tiles 10, 200, 300 are made of the same type of material, they may be made of materials that have different colors, textures, or other aesthetic properties.
While the invention has been described with respect to certain embodiments, the description is intended to be exemplary, rather than limiting. Modifications and changes may be made within the scope of the invention, which is defined by the appended claims.
