Referring initially to FIGS. 1-3, a vertical support or wall 10 supporting an illustrative acoustical wall covering system 12 of the present disclosure is shown. In the illustrative embodiment, the wall 10 includes a drywall portion 14 with a lower section covered with wall carpet 16. Illustratively, sound insulation 18 extends above the wall carpet 16. The sound insulation 18 may comprise a semi-rigid one inch thick insulation board. The upper portion of the wall 10, including the sound insulation 18, is covered by flexible material, illustratively acoustical fabric 20 including a plurality of laterally spaced, longitudinally extending pleats 21.

The fabric 20 illustratively extends between upper and lower mounting assemblies 22 and 24 which are secured to the wall 10. The upper mounting assembly 22 includes a pleating bracket 26 positioned proximate the ceiling 28 and configured to pleat and secure an upper end of the fabric 20. As further detailed herein, the pleating bracket 26 is supported by a header 30, illustratively a 2×4 wood nailer. A lower end of the fabric 20 is supported by a footer 32, illustrative a 2×4 wood nailer. More particularly, the lower end of the fabric 20 may be directly secured to the footer 32 through conventional fasteners 33, such as nails or staples. Finish trim 34 may cover the fasteners 33 and the lower end of the fabric 20.

With reference to FIGS. 1-3, the illustrative upper mounting assembly 22 includes bracket 26 secured directly to the wall 10. An alternative upper mounting assembly 22′ is shown in FIGS. 4-6 as including bracket 26 removably coupled to a receiver 36. The bracket 26 illustratively includes a plurality of longitudinally extending planar mounting portions 38 and a plurality of longitudinally spaced u-shaped pleating portions 40. Each pleating portion 40 extends laterally intermediate adjacent mounting portions 38.

Each illustrative mounting portion 38 includes a planar body 42 having a plurality of mounting apertures or openings 44 which may be utilized to secure the bracket 26 directly to the header 30 through fasteners 45, such as nails or screws (FIG. 1). The body 42 of each mounting portion 38 includes an upper edge 46 and a lower edge 48. A clearance recess 50 extends downwardly from the upper edge 46 which reduces the amount of material required for the bracket 26 and may receive fasteners 52, such as nails or staples, for securing wall fabric 20 directly to the header 30. Upper mounting tabs 54 extend upwardly at opposing ends of each clearance recess 50 (FIG. 6). The bracket 26 defines a form for a user securing the wall fabric 20 to the header 30. In the illustrative embodiment, four staples 52 are received between each pleating portion 40 of the bracket 26, including one staple 52 against each side of adjacent pleats 21 and two staples 52 positioned therebetween. It should be appreciated that the number and placement of fasteners 52 may vary.

With reference to FIGS. 7 and 8, each pleating portion 40 includes laterally spaced first and second side walls 56 and 58, and an end wall 60 connecting the first wall 56 and the second wall 58. The end wall 60 defines an upper shelf or platform 62 supporting an upwardly extending pointed projection or tab 64 configured to engage wall fabric 20. Clearance slots 65 and 67 are positioned intermediate the first and second side walls 56 and 58 and the pointed tab 64, respectively.

The bracket 26 further includes a plurality of longitudinally spaced connecting webs 70 extending between adjacent mounting and pleating portions 38 and 40. Upper and lower clearance slots 66 and 68 extend laterally intermediate the mounting portions 38 and the pleating portions 40, above and below the connecting webs 70.

In the illustrative embodiment, the bracket 26 is formed of a polymer. More particularly, in one illustrative embodiment, the mounting portions 38, the pleating portions 40, and the connecting webs 70 may be integrally injection molded from acrylonitrile butadiene styrene (ABS). Illustratively, the ABS of bracket 26 is fire resistant and may be black or of a color similar to that of the fabric 20 such that it is not clearly visible to a ground based observer.

In the illustrative upper mounting assembly 22′ of FIGS. 4-6, the receiver 36 includes a body portion 80 having a rear wall 82 configured to be mounted to the vertical wall 10. A plurality of strengthening ribs 84 are illustratively supported by the rear wall 82. A plurality of mounting apertures or openings (not shown) may be formed within the rear wall 82 and are configured to receive fasteners 85, such as screws, to secure the receiver 36 to the header 30. The receiver 36 further includes an upper support 90 secured to the upper end of the rear wall 82, and a lower support 92 secured to a lower end of the rear wall 82. An upper slot 94 is supported by the upper support 90 and is positioned laterally forward of the rear wall 82. The upper slot 94 is defined by a pair of opposing walls 95a, 95b. A lower slot 96 is supported by the lower support 92 and extends below the upper slot 94. The lower slot 96 is defined by a pair of opposing walls 97a, 97b and is illustratively positioned laterally forward of the rear wall 82 in alignment with the upper slot 94.

The bracket 26 is illustratively received intermediate the upper and lower slots 94 and 96 of the receiver 36. More particularly, the mounting tabs 54 of the mounting portions 38 are slidably received within the upper slot 94, while the lower edges 48 of the mounting portions 38 are slidably received within the lower slot 96. The clearance slots 66 and 68 receive outer walls 95b and 97b of the receiver 36.

An insert or mounting strip 98 is supported by the upper support 90 of the receiver 36. In one illustrative embodiment, the mounting strip 98 defines a door or panel removably received within an access opening 100 in the upper support 90 of the receiver 36. The mounting strip 98 is illustratively formed of a material softer than the material of the body portion 80 of the receiver 36. In one illustrative embodiment, the body portion 80 of the receiver 36 is formed of ABS, while the mounting strip 98 is formed of a polypropylene. The softer material of the mounting strip 98 may be used to facilitate insertion of fasteners 52, such as nails or staples, to secure the fabric 20 thereto. The body portion 80 and the mounting strip 98 may be formed from conventional manufacturing processes, illustratively through extrusion.

The upper support 90 of receiver 36 may include an intermediate vertical wall 97 for added structural support. Illustratively, a fastener insert 99 is received with an outwardly facing cavity defined between wall 97 and opening 100. The fastener insert 99 is illustratively formed of a material (e.g., plastic or wood) configured to receive fasteners 52, such as staples or nails. The lower support 92 of the receiver 36 may include a downwardly facing opening 101 configured to receive an upper end of sound insulation 18 therein.

As shown in the illustrative embodiment of FIG. 5, the fabric 20 is wrapped around the pleating portions 40 of the brackets 26 and secured on upwardly extending tabs 64. The upper end of the fabric 20 may be secured to a front surface 102 of the fastener insert 99 through fasteners 52, such as nails or staples. The mounting strip 98 is then secured in place, illustratively in a tongue-in-groove type manner, to the upper support 90 of the receiver 36 within access opening 100 to cover the fasteners 52 and provide a finished appearance. The fabric 20 is thereby trapped between the lower end of the mounting strip 98 and the receiver 36.

As noted above, in certain illustrative embodiments, the bracket 26 may be secured directly to the header 30 through fasteners 52 without the use of the receiver 36. In other embodiments, the bracket 26 is removably supported within the receiver 36 which, in turn, is secured to the header 30 through fasteners 45.

To install the illustrative system 12 of the present disclosure, the mounting portions 38 of each bracket 26 may be coupled to the header 30 of the wall 10 directly through fasteners 45. In alternative embodiments, the brackets 26 are removably supported within receivers 36 through sliding receipt within slots 94 and 96.

After the bracket 26 has been installed on the wall 10, either directly to the header 30, or through sliding receipt within the receiver 36 which is secured to the header 30, fabric 20 is hung and pleated. More particularly, the fabric 20 is wrapped around the side walls 56, 58 and end walls 60 of the pleating portions 40 and then secured to the tabs 64. The upper end of the fabric 20 is then either secured directly to the header 30 by fasteners 52 received within recesses 50 of the bracket 26, or by fasteners 52 received within the fastener insert 99 of the receiver 36 and covered by mounting strip 98. As detailed above, the bracket 26 defines a form for the fasteners 52 to aid the installer in securing the fabric 20 to the header 30. The lower end of the fabric 20 is then secured to the footer 32 and covered by trim 34.

The bracket 26 of the present disclosure assists in efficient, safe and reliable installation of aesthetically pleasing wall covering systems 12. More particularly, the bracket 26 defines a fastener form, is light-weight and easy to handle, and has hooks not visible to the typical observer.
