DETAILED DESCRIPTION

[0041] As stated herein, the objective of the present disclosure is to provide an improved acoustic locking ceiling baffle, and an improved dynamic acoustic locking ceiling system, along with improved methods for installing the locking ceiling baffles and creating the dynamic acoustic locking ceiling system.

[0042] Referring to the drawings, wherein like reference numerals refer to the same or similar features in the various views, FIGS. 1 through 6 show different views of the improved locking baffle 10. FIG. 1 shows the resulting baffle 10 after being folded into shape, resulting in a locking mechanism 12 at the top of the ceiling baffle 10. The ceiling baffle 10, which is made in the preferred embodiment, from a single sheet of 9 mm polyester felt or PET Felt, and is intended to be folded into a rectangular or a slab shape, approximately 88 inches long, 8.68 inches high and 2.125 inches thick. One example for holding the slab baffle 10 in its shape includes the use of one or more locking pieces 14. As shown in FIGS. 1 and 10, the ceiling baffle 10 comprises a first outer sidewall 60 and a second outer sidewall 61 that are spaced apart from one another by an interior space or air gap 48. The ceiling baffle 10 further comprises a bottom wall 62 that forms a bottom end of the ceiling baffle 10 and a top wall 63 opposite the bottom wall 62 that forms a top end of the ceiling baffle 10. The first and second outer sidewalls 60, 61 extend from the bottom wall 62 to the top wall 63. The ceiling baffle 10 further comprises a first inner sidewall 64 adjacent to the first outer sidewall 60 that extends from the top wall or top end 63 of the ceiling baffle 10 into the interior space 48 and a second inner sidewall 65 adjacent to the second outer sidewall 61 that extends from the top wall or top end 63 of the ceiling baffle 10 into the interior space 48. The first inner sidewall 64 terminates in a first distal end 67 that is spaced from the bottom wall 62 and the second inner sidewall 65 terminates in a second distal end 68 that is spaced from the bottom wall 62.

[0043] FIG. 2A shows the ceiling baffle 10 prior to being constructed into its resulting shape. The unfolded or flat ceiling baffle 10 is made from a single piece of material, pre-scored for easy folding, and has various cutouts for the shape of the baffle 10 and for other functions, such as the locking mechanism as described below.

[0044] As disclosed below, there are numerous ceiling baffle shapes and designs that can be constructed in accordance with the present disclosure. The portions of the ceiling baffle 10 that will make up the locking mechanism 12 are located such that when the sides 18 are folded at the side score lines 20, the locking mechanism 12 will be accessible for locking the ceiling baffle 10 onto the ceiling as disclosed below. Further, the ends 22 are also folded at the end score lines 24 during assembly of the ceiling baffle 10. This configuration allows the ceiling baffle 10 to be transported flat (FIG. 2A) and easily built or assembled at the installation site. FIG. 2B shows an enlarged end of the ceiling baffle 10 prior to assembly.

[0045] FIG. 3 show an enlarged drawing of the locking piece 14, different than the locking mechanism 12, which is one example used to hold the ceiling baffle 10 together. The locking piece 14 in the preferred embodiment is also made of PET Felt and is sized and shaped to be inserted into the slab baffle at one or more insert locations 16, once folded to hold the slab baffle in its rectangular shape. The insert locations 16 comprise openings 17 in the top wall 63 of the ceiling baffle 10. The ceiling baffle 10 is elongated along a longitudinal axis A-A from a first end 70 to a second end 71. The insert locations 16 or openings 17 are spaced apart from one another in a direction of the longitudinal axis A-A. Each of the insert locations 16 or openings 17 is elongated along a respective plane P that is orthogonal to the longitudinal axis A-A. The locking piece or pieces 14 can be inserted into the top of the slab baffle 10 at the insert locations 16 as shown in FIG. 1. In the preferred embodiment, the locking piece 14 is 2 inches at the top 26 and tapers down to sides 28 of 1 7/16 inches. The locking piece 14 is also 1 7/16 high and has an arrow shaped edge 30 to assist in holding the ceiling baffle 10 together while resisting removal form the insert locations 16. The locking piece 14 has a top portion 50, a first side portion 51 extending downwardly from the top portion 50, and a second side portion 52 extending downwardly from the top portion 50. The top portion 50 has a top surface 57 and a bottom surface 58 opposite the top surface 57. The first and second side portions 51, 52 extend downwardly from the bottom surface 58. The second side portion 52 is spaced apart from the first side portion 52. The first side portion 51 has an inner surface 53 and the second side portion 52 has an inner surface 55. A first locking surface 54 extends from the inner surface 53 of the first side portion 51 towards the inner surface 55 of the second side portion 52. In the exemplified embodiment, the first locking surface 54 extends perpendicularly from the inner surface 53 of the first side portion 51. A second locking surface 56 extends from the inner surface 55 of the second side portion 52 towards the inner surface 53 of the first side portion 51. In the exemplified embodiment, the second locking surface 56 extends perpendicularly from the inner surface 55 of the second side portion 52.

[0046] The resulting shape of the locking mechanism 12 on the ceiling baffle 10 is shown in detail in FIG. 4, and is created by cutting away portions 32 of the ceiling baffle 10 (see FIGS. 1 and 6 through 11 for exemplary locations of the locking mechanism 12 on the ceiling baffle 10). The locking mechanism is sized to fit into the recessed portion 42 of a ceiling hanger 40, such as a standard UNISTRUT metal framing system (shown in FIG. 5), without the need for additional tools, clips or additional attachment devices.

[0047] The locking mechanism 12 is design is a double arrow 34, with recesses 36 below the double arrow 34 and an arrow recess 38 between the double arrows 34. The locking mechanism 12 is particularly designed or configured to mate with a ceiling hanger, as described below. However, other locking mechanisms 12 can be designed and configured (using the ceiling baffle material or other material) to mate with the same ceiling hanger described herein, or to mate with other ceiling hangers, without departing from the spirit and scope of the invention. For example, magnets embedded into the ceiling baffle 10 can be used to attach the ceiling baffle 10 to any metal ceiling structure.

[0048] The locking mechanism 12 is created by cutting away the PET Felt to leave the double arrow shape 34 with the cutaway portion 38 between the double arrows 34 to allow for ease of insertion into the ceiling hanger in accordance with the present disclosure. Due to the location of the locking mechanism 12 on the ceiling baffle 10, the locking mechanism 12 is also 9 mm thick, but there are two locking mechanisms 12 for each location, and they are sized to fit into the recessed portion of a standard ceiling hanger, such as a standard UNISTRUT metal framing system, without the need for additional tools, clips or additional attachment devices. One or more locking mechanisms 12 can be designed into each ceiling baffle 10 depending on the length and need of the ceiling baffle 10.

[0049] FIG. 5 shows a standard UNISTRUT metal framing system, including the recessed portion 42, the sides 44 of the ceiling hanger 40, and the J-shaped ends 46. To install the locking mechanism 12 of the ceiling baffle 10 into the UNISTRUT ceiling hanger 40, the ceiling baffle 10 is located such that the double arrows 34 can be slid into the recessed portion 42 of the ceiling hanger 40 to be held in place by the sides 44 of the ceiling hanger 40 and the J-shaped ends 46 on the sides 44. Additionally, the ceiling baffle 10 can be placed in the proper location and pushed or snapped into place such that the double arrows 34 compress towards the arrow recess 38 and/or toward the recesses 36 below the double arrows 34 to fit past the J-shaped ends 46 on the sides 44 of the ceiling hanger 40. Once past the J-shaped ends 46, the double arrows 34 spring back or expand back to their normal position inside ceiling hanger 40.

[0050] Different sized and shaped locking pieces 14 (for holding the ceiling baffle 10 in its folded position) and locking mechanisms 12 (for installing the folded ceiling baffle 10 into the ceiling hangers 40) can be created depending on need, based on the size and shape of the ceiling baffle 10 and the ceiling hangers 40, or on any other device for which the ceiling baffle 10 will be attached. Further, FIG. 1 shows five locking pieces 14 and one locking mechanisms 12 for the ceiling baffle 10, however, each baffle 10 can be configured with more or less locking pieces 14 or locking mechanisms 12 depending on the need, and based on the configuration of the ceiling baffle 10 and the location and number of the ceiling hangers 40 on the ceiling.

[0051] FIG. 6 shows the improved locking mechanism 12 of the ceiling baffle 10 prior to and after being inserted into the UNISTRUT hanger 40 in which the locking mechanism 12 can be seen up and inside the hanger 40 with the two ends of the double arrow 34 locked in the inside of the J-shaped ends 46 of the hanger 40, from FIG. 5.

[0052] FIG. 7 shows a perspective views of multiple locking ceiling baffles 10 installed in accordance with the present disclosure. FIGS. 8 through 10 show different views of the locking ceiling baffle 10, including the front elevation (FIG. 8), top perspective detail (FIG. 9) and the air gap 48 (FIG. 10), which increases the acoustic absorbency by approximately 50%. The assembled ceiling baffle 10, in the preferred embodiment, is 84 inches long, with two locking mechanisms 12 10.47 inches (on center) from the ends, and provides the look of a solid 2.125 inch block of material, but instead uses a 1.5 inch air gap 48 to reduce acoustics and weight.

[0053] A system may include more or less locking ceiling baffles 10 depending on the size of the room. Further, the present disclosure is not limited to the particular shaped baffles described herein, as other shaped locking ceiling baffles 10 can be created by folding the pre-scored piece of PET Felt used in the present disclosure with different dimensions to obtain similar results, as disclosed below.

[0054] Another embodiment, similar to the disclosure above, of ceiling baffles 10, is shown in FIGS. 11A through 11E, which show an alternative embodiment design ceiling baffle 10 in accordance with the present disclosure. FIG. 11A shows a perspective view of an assembled ceiling baffle 10, but instead of a rectangular shape as detailed above, the alternative embodiment forms a wedge 110 ceiling baffle 10 when assembled. At its widest point, the wedge ceiling baffle 10 is 2.125 inches wide, but the ceiling baffle 10 tapers to a wedge 110 at the other end of the ceiling baffle.

[0055] FIGS. 11B through 11E show that the wedge ceiling baffle 10 design can be manufactured in various sizes and shapes to be configured for different size and shaped ceilings, to create the wedge baffle image. These figures show different lengths for the various wedge ceiling baffles 10. FIG. 11B for example shows a large wedge ceiling baffle 10 that is 114 inches long and 8.68 inches deep, while FIG. 11C shows a medium wedge ceiling baffle 10 that is 90 inches long and 8.68 inches deep, and FIG. 11D shows a small wedge ceiling baffle 10 that is 43.5 inches long and 8.68 inches deep. Additionally, FIG. 11E shows a wedge ceiling baffle 10 that is a custom size from 43.5 inches long to 114 inches long and 8.68 inches deep. Of course, other size carved ceiling baffles 10 can be manufactured in keeping within the scope of the invention.

[0056] Yet another embodiment of ceiling baffles 10, similar to the disclosure above is shown in FIGS. 12A through 12N, which show an alternative embodiment design ceiling baffle 10 in accordance with the present disclosure. FIGS. 12A through 12D show perspective views of an assembled ceiling baffles 10, but instead of a rectangular shape as detailed above, the alternative embodiments form trapezoid (FIGS. 12A and 12C) or parallelogram (FIGS. 12B and 12D) shaped ceiling baffles 10 when assembled and viewed from a front elevation. However, each of these shapes are 3.75 inches deep (although other depths can be designed in accordance with the disclosure), and are assembled into a triangular profile ceiling baffle 10, when view from the sides. These ceiling baffles 10 provide an internal air gap of 6.44 inches and boast an NRC rating of 1.55.

[0057] FIGS. 12E through 12N show that the triangular ceiling baffle 10 design can be manufactured in various sizes and shapes to be configured for different size and shaped ceilings, to create the triangular baffle image. These figures show different lengths for the various wedge ceiling baffles 10, including the four different configurations shown in FIGS. 12A through 12D. FIGS. 12E and 12J for example show large triangular ceiling baffles 10 that are 119 inches and 108 11/16 inches long, respectively, while FIGS. 12F and 12K show medium triangular ceiling baffles 10 that are 95 inches and 86.75 inches long, respectively. FIGS. 12G and 12L show triangular ceiling baffles 10 that are 47.5 inches and 43 inches long, respectively and FIGS. 12H and 12M show small triangular ceiling baffles 10 that are 23.75 inches and 23.75 inches long, respectively. Additionally, FIGS. 12I and 12N show a triangular ceiling baffles 10 that are custom size from 23.75 inches long to 119 inches long and 108 11/16 inches long, respectively. Of course, other size triangular ceiling baffles 10 can be manufactured in keeping within the scope of the invention.

[0058] As described herein, the material used in the preferred embodiment is polyester felt and is 99% recycled. The ceiling baffles 10 in the preferred embodiment are 9 mm thick, and the panel thickness (after assembly) is 2.125 inches thick, with a standard size of 8.68 inches by 88 inches. The edge options are exposed felt, and maintenance includes occasional vacuuming to remove particulate matter and air-borne debris or dust. Compressed air can be used to dust off the material in difficult to reach areas and for large assemblies.

[0059] The felt comes in numerous colors, including white, cream, light grey, light brown, brown, matte grey, charcoal, black, yellow, mango, orange, red, lavender, lime, green, light blue and dark blue. Of course, the ceiling baffles 10 can be manufactured in many other colors and the present disclosure is not limited to these specifications and colors, as these are merely the specifications and colors for the preferred embodiments and alternative embodiments.

[0060] FIG. 13 shows a chart for the acoustic testing standard ASTM C423 for the ceiling baffles 10 in the preferred embodiment. The chart indicates testing on the preferred embodiment and provides the results of the sound absorption coefficient for the ceiling baffle 10 at various frequencies. The test arrangement used a +100 mm air layer filled with 50 mm rock wool board. As described herein, the noise reduction coefficient at 500 Hz 70 is 0.76 72, and at 1000 Hz 74 is 1.00 76. Further, the ceiling baffles 10 are fire rated as UL tested ASTM E-84: Class A.

[0061] FIG. 14 shows the graph 78 of the sound absorption coefficient against frequency for the same test, with the sound absorption average (SAA) 80 of 0.76, and the noise reduction coefficient (NRC) 82 of 0.75.

[0062] Alternative embodiments exist for attaching a slab baffle 10 to a ceiling. One alternative embodiment is shown in FIGS. 15A and 15B and utilizes a cable suspension system 150 in which the slab baffles 10 have an embedded cable gripper 152 such that the slab baffle 10 can be snapped into deck-mounted aircraft cables 154. The aircraft cables 154 can be arranged in any desired pattern or configuration and once installed, the excess cable 156 will protrude through the slab baffle 10 and can be cut off with a scissors or left alone.

[0063] Another alternative embodiment for attaching a slab baffle 10 to a ceiling is shown in FIGS. 16A and 16B and utilizes a magnetic connection system 160. The slab baffles 10 are embedded with magnets 162 such that they will connect and hang onto any ceiling or ceiling structure 164 that is made from any ferrous metal material, such as a Unistrut, tee bar or steel joist, among others. The slab baffle 10 containing the magnet 162 can be snapped into place adjacent the ferrous metal structure in any desired pattern or configuration.

[0064] Additionally as disclosed above, an alternative embodiment for assembling the ceiling baffle 10 of the present disclosure includes using magnets embedded into the ceiling baffle 10 so that when the flat ceiling baffle 10 is folded and assembled into its final form, the embedded magnets will hold the ceiling baffle 10 in that form without the need for the locking pieces 14 disclosed herein. FIG. 17 shows the flat ceiling baffle 10 with one or more magnets 170 embedded into the baffle 10 on one side, and with one or more magnets 172 embedded into the baffle 10 on the other side, so that when the ceiling baffle 10 is assembled, the magnets 170 and the magnets 172 will come in close contact or actually make contact with each other, thereby holding the assembled ceiling baffle 10 together. These magnets 170, 172 are different than the magnets 162 used for the locking mechanism 12 disclosed herein and in FIGS. 16A and 16B. Although, in certain designs the same magnets can be used for both purposes.
