Definitions

  • Back boxes are often utilized for speaker installation or other in-wall or in-ceiling component installation to provide a defined and protective housing for a speaker or other in-wall or in-ceiling component.
  • many municipal or state building codes require back boxes to be utilized with any in-wall or in-ceiling components in commercial construction.
  • Known back boxes are usually limited to use with only one size of an in-wall or in-ceiling component and are often manufacturer specific. In other words, each speaker size requires a different back box corresponding to the specific speaker size and often a different back box is required for each speaker and component manufacturer.
  • a distributor or a custom installer must therefore stock several differently-sized back boxes from multiple manufacturers to accommodate the variously-sized speakers or components of multiple manufacturers that are typically installed in home, business and commercial environments.
  • known back boxes often require the in-wall or in-ceiling component to be installed in certain positions within the back box and between the two supports thereby making it extremely difficult to utilize one back box for precise installation of differently-sized speakers or components.
  • a universal back box that can be used for a plurality of speaker sizes wherein the speaker can be installed at different locations within the back box and between the supports while the back box retains or improves the acoustic performance and meets all applicable building codes.
  • Embodiments of the present invention solve the above-described problems and provide a distinct advance in the art of in-wall or in-ceiling back boxes. More particularly, certain embodiments of the invention provide back boxes that allow placement of differently-sized in-wall or in-ceiling components in a finished wall or ceiling. Further, such a configuration allows differently-sized speakers and other in-wall equipment to be easily and accurately positioned at multiple locations within the back box and between wall or ceiling supports.
  • the present invention provides a method for mounting of an in-wall component between two supports using the back box of the present invention.
  • the method generally includes coupling a back box to two wall or ceiling supports, installing drywall over the back box, forming an aperture in the drywall, and removing at least a portion of a filler material present in the back box to receive the in-wall or in-ceiling component therein.
  • FIG. 1 is a top perspective view of a universal back box configured in accordance with certain embodiments of the present invention
  • FIG. 2 is a top perspective view of a back box housing configured in accordance with a certain embodiment of the present invention

  • given lengths of flange 50 may be intermittently spaced around inner surface 40 of side walls 16 , 18 , 20 , 22 .
  • Flange 50 is generally configured to receive an in-wall component mounting template thereon.
  • flange 50 has an L-shape cross-section that is spot welded at intervals along side walls 16 , 18 , 20 , 22 .
  • flange 50 may be any shape and any length suitable for use in the present invention.
  • back wall 24 is generally rectangular in shape and includes an inner face 52 and an outer face (not shown).
  • Back wall 24 generally lies in a plane perpendicular to side walls 16 , 18 , 20 , 22 wherein back wall 24 is either integral with or coupled to side walls 16 , 18 , 20 , 22 at or near back edge 46 of side walls 16 , 18 , 20 , 22 .
  • mounting tabs 26 are generally configured to facilitate coupling of back box 10 to at least one support member.
  • Mounting tabs 26 generally extend outwardly from corners 38 .
  • Mounting tabs 26 generally define at least one aperture 54 therethrough that is sized to receive a fastener for fastening back box 10 to a support member.

  • Filler material 14 may be selected based on a variety of secondary considerations.
  • One embodiment uses spray foam 14 because the spray foam 14 functions as a vapor barrier that satisfies building code requirements of jurisdictions wherein a vapor barrier is required for exterior walls. Therefore, in these jurisdictions, spray foam 14 allows back box 10 to be utilized for mounting an in-wall component in an exterior wall.
  • filler material 14 may also be selected based on its ability to generally improve acoustic performance of an in-wall or in-ceiling component including specifically dampening or eliminating vibration of side walls 16 , 18 , 20 , 22 , and back wall 24 of housing 12 or allowing an installer to customize the air space behind an in-wall or in-ceiling speaker to improve acoustic performance of the component.
  • Other considerations when selecting filler material 14 include, but are not to be limited to, cost of material, insulative capabilities, heat resistance, and fire retardant properties.
  • universal back box 10 is installed in a wall or a ceiling between two building support members 60 , as shown in FIG. 5 .
