DESCRIPTION OF THE INVENTION

[0015] In the following detailed descriptions of the acoustic material frame assembly, reference is made to the accompanying drawing that form a part hereof, and in which are shown, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structure changes may be made or other method steps and sequence thereof may be used without departing from the scope of the present invention. The acoustic material frame assembly is herein described as used in home and business environments. The frame assembly can have uses in other environments when sound absorption is desired.

[0016] Referring to FIGS. 1 to 3, there is shown an acoustic material frame assembly indicated generally at 10. Frame assembly 10 is a do-it-yourself snap-fit assembly having a plastic tube frame 11 that encloses acoustic material 12. Frame 11 can be assembled very quickly without the need for power tools, saws, staple guns, tape measures, nails, screws, staples, glue, adhesive compounds or other construction materials. Frame 11 houses, holds or otherwise encloses and compresses acoustic material 12 and when covered with fabric slipcover 13 or other similar material, can be placed in an area where sound absorption is needed and used to control echo, standing waves, slap-back or other problematic sound waves from any source. Frame 11 is manufactured using a thermoplastic material such as polylactic acid (PLA), but can also be manufactured using other plastics or thermoplastics. Frame 11 can be manufactured in such a way as to apply industry standard equipment such as plastic injection molding, plastic extrusion, computer numerically controlled (CNC) milling, or additive manufacturing (AM) such as three dimensional (3D) printing or other related manufacturing equipment.

[0017] Frame 11 has four-way corner connectors 14, 16, 17 and 18 and six-way T-connectors 19, 21, 22 and 23 that are four inches in depth, thereby allowing tubing 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 44, 46, 47, 48, 49, 51, 52 and 53 to be coupled by snap-fitting or other methods onto corner connectors 14, 16, 17 and 18 and T-connectors 19, 21, 22 and 23 to assemble frame 11 to have a depth of four inches. Corner connectors and T-connectors having a two-inch depth can be used to assembly of frame 11 having a two-inch depth or other sized connectors can be used depending on the depth of the acoustic material and level of sonic absorption required. Tubing 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 44, 46, 47, 48, 49, 51, 52 and 53 are extruded square shape tube plastic cut to precise lengths which are connected together with four-way corner connectors 14, 16, 17 and 18 and six-way T-connectors 19, 21, 22 and 23. Tubing 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 44, 46, 47, 48, 49, 51, 52 and 53 can have other shapes such as round, rectangle, triangle and other multi-sided designs. Frame 11 creates a frame member that allows the user to easily insert acoustic material 12 or other material into the interior 20 of frame 11.

[0018] Frame 11 can be made to have the shape of a square, rectangle, box, triangle or other shape desired by the user. T-connectors 19, 21, 22 and 23 are adapted to accommodate, but not limited to, four-inch thick acoustic material, depending on the type of sound waves to be absorbed, such as either high and midrange or low frequencies.

[0019] Once frame 11 is assembled, it is covered with fabric slipcover 13. Fabric slipcover 13 is preferably an acoustically transparent fabric custom sewn slipcover conducive to penetrable sound waves. Fabric slipcover 13 can have a variety of colors and designs for decorative purposes and to match the user's decor. Fabric slipcover 13 also prevents insulation particles from acoustic material 12 from escaping into the air. Fabric slipcover 13 is held tight and secured in the back of frame 11 by a fastener 15, such as a drawstring, Velcro fasteners or other hook and loop fasteners, snaps, ties, hooks, zippers, magnets or other fastening methods. The sides and ends of slipcover 13 can also be sewn together to hold slipcover 13 on frame 11. Slipcover 13 easily fully covers the front, back and sides of the four-inch deep frame 11 once the device is assembled. Slipcover 13 is made of acoustically sensitive fabric that allows sound waves to penetrate into acoustic material 12, while at the same time preventing particles from acoustic material 12 from escaping into the surrounding environment. The bottom of slipcover 13 can also have a securing flap (not shown) that is attachable to slipcover 13 with Velcro fasteners, other hook and loop fasteners, draw-string ties, zippers, snaps, magnets and the like.

[0020] As shown in FIG. 7, standoffs 19, such as two-inch standoffs, affixed to a mounting surface 21 are used to support and allow frame assembly 10 to stand-off or float from mounting surface 21. The gap between frame assembly 10 and mounting surface 21 allows sound waves to pass through acoustic material 12, bounce off surface 21 and enter acoustic material 12 a second time substantially preventing the sound wave from re-entering the desired area. Standoffs 19 are affixed to mounting surface 21 by using Velcro fasteners or other hook and loop fasteners, snaps, magnets, slip-notches, clips or similar methods. An attaching apparatus, such as a magnet, hook and loop fastener, double-sided tape and the like can also be used to mount frame assembly 10 directly on mounting surface 21.

[0021] Corner connectors 14, 16, 17 and 18 are four-inch corner connectors adapted to accommodate the desired four-inch thick depth of the acoustic material used and four-inch T-connectors. The depth of frame 11 is determined by selecting four-inch corner connectors and T-connectors or other sized connectors, such as two-inch connectors, depending on the depth of the acoustic material and level of sonic absorption desired.

[0022] Corner connectors 14, 16, 17 and 18 are identical in structure and function. The details of corner connector 14 shown in FIG. 4 are included in corner connectors 16, 17 and 18, the following description is directed to corner connector 14.

[0023] Corner connector 14 has an upright member 54 with transverse trunks 56, 57, 58 and 59 projecting outwardly at right angles from the ends of upright member 54. Trunks 56, 57, 58 and 59 telescope and snap-fit into the ends of tubing 24, 33, 44 and 53. Trunks 56, 57, 58 and 59 are shaped complimentary to the shape of tubing 24, 33, 44 and 53, such as rectangular shaped and the like, to facilitate snap fitting. Trunks 56, 57, 58 and 59 have flexible tabs 61, 62, 63 and 64 that are adapted to flex inwardly to allow insertion of trunks 56, 57, 58 and 59 into the ends of tubing 24, 33, 44 and 53. The ends of tabs 61, 62, 63 and 64 each have an upright cylindrical shaped boss 66 that snap-fit into corresponding holes 67 in the ends of tubing 24, 33, 44 and 53.

[0024] Similarly, T-connectors 19, 21, 22 and 23 are identical in structure and function. The details of T-connector 19 shown in FIG. 5 are included in T-connectors 21, 22 and 23, the following description is directed to T-connector 19.

[0025] T-connector 19 has an upright member 68 with trunks 71, 72, 73, 74, 75 and 76 projecting outwardly in opposing directions and right angles from the ends of upright member 68. Trunks 71, 72, 73, 74, 75 and 76 are adapted to telescope into the ends of tubing 26, 27, 36, 46, 47 and 56 with a snap-fit to connect tubing 26, 27, 36, 46, 47 and 56 with T-connector 19. Trunks 71, 72, 73, 74, 75 and 76 are shaped complimentary to the shape of tubing 26, 27, 36, 46, 47 and 56, such as rectangular shaped and the like, to facilitate snap fitting. T-connector 19 has flexible tabs 77, 78, 79, 81, 82 and 83 that are adapted to flex inwardly to allow insertion of trunks 71, 72, 73, 74, 75 and 76 into corresponding ends of tubing 26, 27, 36, 46, 47 and 56. The ends of tabs 77, 78, 79, 81, 82 and 83 each have an upright cylindrical shaped boss 84 that snap-fit into corresponding holes 86 in the ends of tubing 26, 27, 36, 46, 47 and 56. A transverse spike member 69 extends outwardly from upright member 68. Spike member 69 is adapted to engage and stabilize acoustic material 12 located within frame 11.

[0026] Frame assembly 10 can be mounted, suspended, hung or installed on a wall, ceiling or other surface, or let free-stand in the desired area. Frame assembly 10 is mounted to flat target surface with fasteners such as Velcro or other hook and loop fasteners, clips, magnets, double-sided tape, hooks, screws, wall anchors or other methods located on a selected area on the back of frame assembly 10 for flush and even mounting. Also mounting devices, such as standoffs 19, can be applied to mounting surface 21 or other target surfaces that frame assembly 10 connects via Velcro or other hook and loop fastener, clips, magnets, double-sided tape, wall anchors, screws or other methods. This allows for the entire frame assembly 10 to stand-off away and be spaced a fixed distance from the targeted mounting surface, thus allowing frame assembly 10 to capture additional sound waves.

[0027] The method of making frame assembly 10 includes assembling frame 11 starting with snap-fitting or otherwise flexing tabs 61, 62, 63, 64, 77, 78, 79, 81, 82 and 83 inwardly and inserting tubing 26, 27, 28, 46, 47 and 48 into the ends of corner connectors 16 and 17 and T-connectors 19 and 21 until bosses 66 and 84 snap into holes 67 and 86 to form a side cap assembly 25. The remaining tubing 24, 29, 31, 32, 33, 34, 36, 44, 49, 51, 52, 53, 54 and 56 is snap-fit into the ends of corner connectors 14 and 18 and T-connectors 22 and 23 to form a secondary frame assembly 30 in a similar manner. Acoustic material 12 is then inserted into the open end of secondary frame assembly 30 into engagement with spikes 69 of T-connectors 22 and 23. Cap assembly 25 is then snap-fit onto secondary frame assembly 30 whereby spikes 69 of T-connectors 19 and 21 engage acoustic material 12 and acoustic material 12 is compressed into the interior 20 of frame 11 thus completing the assembly of frame 11. Fabric slipcover 13 is then placed over the top of frame 11 and pulled down to enclose frame 11. Fabric slipcover 13 is pulled tight and secured in the back of frame 11 with fastener 15. The entire frame 11 with encased acoustic material 12 is covered with fitted fabric slipcover 13 which is adapted to be easily pulled over to completely cover frame 11, and secured using a drawstring, ties, zippers, hook and loop, snaps or other like fasteners. The fabric of slipcover 13 has a slight stretch character that allows slipcover 13 to easily fit over frame 11 and encased acoustic material 12. Once frame 11 and acoustic material 12 are covered, frame assembly 10 is complete and ready for installation and use.

[0028] Standoffs 19, such as four 2-inch mounting brackets, can be attached or affixed to target mounting surface 21 to ensure maximum performance of frame assembly 10. Fastening material, such as a magnet, hook and loop fastener, double-sided tape, wall anchors, screws or other fasteners, can be located on the back of acoustic frame assembly 10 to align with standoffs 19 and affixed thereto.

[0029] Frame 11 is preferably constructed and manufactured using a plastic or thermoplastic and can be sourced using recycled plastic. Corner connectors 14, 16, 17 and 18, T-connectors 19, 21, 22 and 23 and tubing 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 44, 46, 47, 48, 49, 51, 52 and 53 of frame 11 are easily manufactured in such a way as to apply industry standard equipment such as thermoplastic injection molding, CNC milling, additive 3D printing or other similar or related manufacturing equipment.

[0030] The acoustic material frame illustrated and described includes several embodiments of the invention. Variations and modifications of the acoustic material frame and acoustic frame materials can be made by a person skilled in the art without departing from the invention.
