[0022] While the present disclosure is susceptible of embodiments in various forms, there is described presently preferred embodiments with the understanding that the present disclosure is to be considered an exemplification and is not intended to limit the disclosure to the specific embodiments illustrated.

[0023] FIG. 1 depicts an example wall system 10 according to the present disclosure. The example wall system 10 includes an interior wall 15 which can include one or more wall components such as moisture and / or wind wrappings / barriers / films (e.g., Tyvek), insulation, masonry blocks, sheathing (e.g., oriented-strand board, plywood), wall panels, studs, framing, interior wall boards, and / or the like. The wall system 10 includes an exterior wall 20 which is coupled to the interior wall 15 via a mounting system 30 as described in further detail herein. The exterior wall 20 can include any suitable assembly (e.g., rainscreen) and / or include one or component components cement boards, mental louvers, brick panels, metal siding, and / or the like. The mounting system 30 includes a bracket 40 and a rail 70. As will be described in further detail herein, the bracket 40 is exemplarily secured to the exterior wall 20 while the rail 70 is secured to the interior wall 15. While the rail 70 is depicted as being secured to an interior wall, it will be recognized that the rail 70 may be connected to the wall 15 through an intermediate structure of (e.g. vertical) rails which are connected to the interior wall, and the (e.g. horizontal) rail 70 is secured to those intermediate rails, for example as is described in the previously noted references.

[0024] During construction of the wall system 10, the interior wall 15 is constructed such that the exterior facing side of the interior wall 15 is complete. The mounting system 30 as described herein facilitates coupling of the exterior wall 20 to the interior wall 15.

[0025] The present inventor recognized that conventional systems for mounting the exterior wall to the interior wall are difficult to install and do not permit adjustment to the position of the exterior wall relative to the interior wall. The wall systems and mounting systems as disclosed herein address these problems and provide other advantages, including ease of coupling an exterior wall to an interior wall and positional adjustment of the exterior wall to the interior wall exemplarily for vertical leveling of the exterior wall.

[0026] Note that while the example wall systems 10 and the example mounting systems 30 described with reference to wall systems with an interior wall and an exterior wall, the example wall systems 10 and the example mounting systems 30 are not limited to wall systems 10 with “interior walls” and “exterior wall”. Instead, the example wall systems 10 and the example mounting systems 30 described herein can be utilized with other walls systems that have a first wall and a second wall such as an interior wall coupled to another interior wall, a glass wall on an interior support walls, and / or a first set of wall panels on a second set on wall panels (e.g., mounting decorative wood panels on panels of interior drywall).

[0027] FIG. 1 depicts the mounting system 30 within a wall system 10. FIGS. 2-5 depict the components of the mounting system 30 in isolation. FIG. 2 depicts the bracket 40 in perspective and FIGS. 3 and 4 respectively depict the rail 70 in front and rear perspective views and a side view in FIG. 5. FIGS. 2-5 depict the mounting system 30 in greater detail. Specifically, FIG. 2 depicts a bracket 40 and FIGS. 3-5 depict a rail 70. The bracket 40 can be coupled to the rail 70, as will be described in greater detail herein below.

[0028] The bracket 40 is exemplarily a unitary construction that may be formed by stamping and bending to form the structures as described herein. In non-limiting examples, the bracket 40 may be constructed of plastic, polymer, fiberglass, or metal. In further non-limiting examples, the unitary construction may be formed by extrusion, printing, molding, casting, or machining. It will be recognized that in other non-limiting implementations, the bracket 40 may be formed of two or more separate components joined by welding, brazing, or other joining methods. The bracket 40 thus includes a bracket body 60 from which other structures of the bracket, including sides 41, 42 and a shelf 62 that extend away from the bracket body 60 in generally orthogonal directions from the bracket body 60. The bracket 40 generally extends longitudinally (see example L axis) between the sides 41, 42, extends laterally (see example T axis) between a closed end 51 and an open end 52, and extends vertically (see example A axis) between an open upper end 55 and lower end 56.

[0029] Sides 41, 42 exemplarily extend orthogonally from opposing ends of the body 60. The sides 41, 42 connect to the body 60 at a corner section 49 which may exemplarily be rounded (as depicted in FIG. 2) if the bracket is formed by bending or may be a sharper corner if constructed in other manners. Each side 41, 42 includes a plurality of edges, and may form points of engagement within the systems as disclosed herein. The sides 41, 42 are exemplarily planar and include end edges 43 on a side opposite the corner section 49. These end edges 43 form the outer extent of the bracket 40 in the lateral (T) dimension and exemplarily face, abut or engage the wall 15 (FIG. 1) during use of the bracket 40. A lower edge 45 of the side 41, 42 exemplarily extends along this lateral (T) dimension. As will be described herein, the lower edge 45 may be further in planar alignment with a lower surface of the shelf 62. The side 41, 42 further includes a leg 46 which depends past the lower edge 45. The leg 46 thus continues the end edge 43 in the vertical (A) dimension, while also forming an exterior edge 44 on side of the leg 46 opposite the end edge 43 and towards the body 60. The leg 46 terminates in a distal end 48 and at the distal end 48 a lip 47 protrudes from the exterior edge 44 further in the lateral direction (T) towards the body 60. As will be described in further detail herein, portions of the sides 41, 42 are shaped and dimensioned to face, abut, or engage portions of the rail 70.

[0030] Shelf 62 exemplarily extend orthogonally from the body 60. The shelf 62 connects to the body 60 at a corner section 61 which may exemplarily be rounded (as depicted in FIG. 2) if the bracket is formed by bending or may be a sharper corner if constructed in other manners. The shelf 62 extends between in the lateral (T) dimension between the sides 41, 42. A gap may exist between the shelf 62 and the sides 41, 42, this gap may be of a distance related to the size or radius of the corner 49. In still further examples, the shelf 62 may be connected to the sides 41, 42, either by welding or other joining, or by unitary construction between the two structures. As noted previously, a lower surface of the shelf 62 may exemplarily be co-planar with the lower edge 45 of the side 41, 42. The shelf 62 and / or the lower edge 45 may be shaped and dimensioned to rest upon or otherwise engage the rail 70 as described in further detail herein.

[0031] As previously noted, in example of the wall system 10, the bracket 40 is secured to the exterior wall 20. The body 60 of the bracket may therefore include at least one, and exemplarily a plurality of, holes 63 therethrough. Fasteners 64 which exemplarily be screws, bolts, or rivets extend through the holes 63 to secure the bracket 40 to the exterior wall 20 (see FIG. 1). As will be described in further detail herein, the shelf 62 includes at least one, and as depicted, a plurality of holes 66 extend through the shelf 62. The holes are each sized and dimensioned so receive a fastener 67 (e.g. a screw, bolt, or rivet) therethrough to secure the bracket 40 to the rail 70. Additionally, at least one hole 66 may be sized and dimensioned to receive a leveling device 68, which exemplarily is a threaded fastener or fastener-like structure as will be described in further detail herein. In such examples, the hole 63 may include threads arranged to engage with the threads of the leveling device 68.

[0032] The rail 70 is depicted in isolation in FIGS. 3-5. The rail 70 generally longitudinally (see example L axis) extends between opposite ends 71,72. The rail 70 extends laterally (see example T axis) between an interior side 74 and an exterior side 73. As explained in further detail herein, the interior side 74 may be secured to the interior wall 15 and the exterior side 73 is in a direction towards the exterior wall 20 (see FIG. 1). and the rail 70 exemplarily extends vertically (see example A axis) between an upper end 75 and an opposite lower end 76.

[0033] The rail 70 exemplarily is constructed as a unitary structure. The rail 70 is exemplarily elongated in the longitudinal (L) dimension and exhibits a consistent cross-section along the length thereof. Thus, while examples of the rail 70 may be constructed by stamping and bending, other examples may include an extrusion process. The rail 70 includes a face section 81, an outward extension 82, a front section 83, and an inward extension 84. The rail sections 81-84 are coupled to each at corners 85. The corners 85 may be rounded as depicted in the figures, exemplarily due to construction of the rail 70 by bending, or may have sharper corners 85, exemplarily of the rail 70 is constructed by other methods.

[0034] The face section 81 includes a plurality of holes 86 that shaped and dimensioned to receive fasteners 87 therethrough. The fasteners 87 may exemplarily be screws, bolts, or rivets. The fasteners secure the rail 70 to interior wall 15 (see FIG. 1).

[0035] The rest of the rail 70 is shaped and dimensioned to facilitate engagement with the bracket 40 as will be described in greater detail herein. The outward extension 82 extends from the face section 81 in a direction away from the interior wall 15. The outward extension 82 includes a plurality of holes 89 therethrough which may serve the purpose of promoting the passage of air, debris, and / or water therethrough. Accordingly, water can drain from the wall system 10 and air ventilation can dry the wall system 10 between the interior wall 15 and the exterior wall 20 to remove moisture therefrom thereby decreasing rot and mold growth between the interior wall 15 and the exterior wall 20. The holes 89 can also improve the insulation rating of the wall system 10 by providing for airflow to dry the insulation and maintain its R-value. While not limited thereto, in an example, the outward extension 82 is orthogonal to the face section 81.

[0036] The front section 83 exemplarily extends in a plane parallel to the face section 81, and front section 83 is spaced apart from the face section 81 by the outward extension 82. The face section 81 and the front section 83 extend from opposite sides of the outward extension 82 and exemplarily extend in opposite directions in the vertical dimension (A).

[0037] The inward extension 84 exemplarily extends in a plane parallel to the outward extension 82. The inward extension 84 extends away from the front section 83 in a direction towards the plane of the face section 81. The inward extension 84 extends from an end of the front section 83 opposite that which the outward extension 82 connects to the front section 83. The inward extension 84 has a length L4 that is less than a length L2 of outward extension 82. The inward extension 84 defines a bearing surface 91 and an abutment edge 92. In certain examples, the outward extension, 82, the front section 83, and the inward extension 84 define a U-shape.

[0038] Referring back to FIG. 1, an example of a wall system 10 which includes an interior wall 15 connected to an exterior wall 20 with a mounting system 30 is provided and a method for coupling the exterior wall 20 to the interior wall 15 with the mounting system 30 is described hereinbelow.

[0039] The rail 70 is fastened to the interior wall 15 using one or more fasteners 87. Note that the number of fasteners 87 and corresponding holes 86 in the rail 70 can vary based on loading requirements and weight limits (e.g., two fasteners per linear foot, eight fasteners per rail section). The longitudinal length of the rail 70 can vary (e.g., eight feet, thirty feet). In certain examples, gaskets, waterproofing materials (e.g., caulk, membranes) fill gaps located between the first rail section 81 and the interior wall 15. The rails 70 can be arranged on the interior wall 15 in rows.

[0040] In preparation for connecting the exterior wall 20 to the interior wall 15, one or more brackets 40 are fastened to sections or panels of the exterior wall 20 using one or more fasteners 64. Note that the number of fasteners 64 and corresponding holes 63 in the shelf 62 can vary based on loading requirements and weight limits (e.g., two fasteners per bracket, three fasteners per bracket). The longitudinal length of the bracket 40 can vary. In one example, the bracket has a longitudinal bracket length BL of 3.0 inches. In certain examples, gaskets or waterproofing materials (e.g., caulk, membranes) fill gaps located between the body 60 and the exterior wall 20.

[0041] A plurality of brackets 40 can be arranged on each section or panel of the exterior wall 20. The location of the bracket 40 on the exterior wall 20 corresponds to the location of the rails 70 on the interior wall 15. For example, three rows of rails 70 are vertically spaced apart from each other on the interior wall 15 and an example panel of the exterior wall 20 has a three by three array of brackets where the rows of brackets are vertically spaced and correspond to the rows of rails and within a row the brackets are horizontally spaced to be distributed across the length of a rail.

[0042] After the bracket(s) 40 are coupled to the exterior wall 20, the exterior wall 20 is vertically lifted (e.g., by hand, by crane). The exterior wall 20 is vertically lifted (see arrow B) such that the distal end 48 of the legs 46 of the bracket 40 are vertically above the bearing surface 91 of the inward extension 84 (see dashed line C). The exterior wall 20 is then moved laterally (T) toward (see arrow D) the interior wall 15, and further moved vertically downwardly (see arrow E) through a channel 95 defined between the abutment edge 92 of the inward extension 84 and the interior wall 15. Vertical downward movement of the bracket 40 is stopped when the lower edge 45 of the bracket 40 and / or the lower surface of the shelf 62 engages and bears on the bearing surface 91 of the rail 70. As such, the bracket 40 and the exterior wall 20 attached thereto is vertically supported by the rail 70 on the interior wall 15.

[0043] Note that the lip 47 can be forced past the abutment edge 92 when the legs 46 are moved through the channel 95. The lip 47 can also prevent or at least resist the bracket 40 from becoming decoupled from the rail 70 in the event the bracket 40 and / or the exterior wall 20 is vertically upwardly moved. In certain examples, the lip 47 also thus requires the dimension of the channel 95 to be slightly larger than the dimension of the rest of the leg 46 absent the lip 47. This may create a space or gap between the end edge of the bracket 40 and the interior wall 15.

[0044] With the bracket 40 vertically supported on the rail 70, the bracket 40 and the exterior wall 20 can be longitudinally moved along the rail 70 to position the exterior wall 20. These features advantageously allow the exterior wall 20 to be properly aligned with the interior wall 15 and / or other panels of the exterior wall 20 (e.g., one panel of the exterior wall can be longitudinally moved along the rail so that seams or patterns of the panel of the exterior wall align with another panel).

[0045] After the bracket 40 and the exterior wall 20 are properly longitudinally positioned, the bracket 40 and the exterior wall 20 can be vertically leveled by inserting the leveling device 68 into one of the holes 66 in the second shelf 62 and operating the leveling device 68 to engage the bearing surface 91 of the rail 70 and vertically move the shelf 62 (and the bracket 40 and the exterior wall 20 away from the bearing surface 91. In one example, at least one of the holes 66 of the shelf 62 has screw threads and the leveling device is a hex-bolt with screw threads. As the hex-bolt is rotated in a first direction (e.g., clockwise) the hex-bolt translates towards the bearing surface 91 in the vertical dimension (A) and engages the rail 70, thus moving the bracket 40 vertically upward in a manner to level the bracket 40 and the exterior wall 20. The hex-bolt can be rotated in an opposite second direction (e.g., counter-clockwise) to reduce the distance between the shelf 62 and the bearing surface 91.

[0046] Once the bracket 40 and the exterior wall 20 are vertically leveled (as described above), one or more fasteners 67 are inserted into one or more holes 66 in the shelf 62 to secure the bracket 40 to the rail 70.
