DETAILED DESCRIPTION

[0030] 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.

[0031] Referring now to the figures and in particular to FIG. 1, there is shown a portion of a wall structure 10. The wall structure 10 includes a backup wall 12 which, as illustrated is a block wall. Other backup wall 12 structures will be recognized by those skilled in the art. The wall structure 10 can further include insulation 14, a rainscreen 16 and a rainscreen support system 18 in accordance with the present disclosure. Other elements may be present between the insulation 14 and the backup wall 12 and between the insulation 14 and the rainscreen 16, such as condensation and waterproof barriers/films and the like. In addition, an air space may be present between the insulation 14 and the rainscreen 16.

[0032] As seen in FIGS. 1 and 5, the rainscreen support system 18 includes primary or backup wall brackets 20, secondary or fixed midspan brackets 22, adjustable vertical support members 24 and horizontal support members 26.

[0033] In a current embodiment, the backup wall brackets 20 include a baseplate or flange 28 that is mounted to the backup wall 12 or structure 10, a transverse or extension leg 30 that extends outwardly from and transverse to the baseplate 28, and fastening fingers 32 that extend from a distal end 34 of, and transverse to the extension leg 30. The fastening fingers 32 are generally parallel to the baseplate 28. The backup wall brackets 20 can be fixed backup wall brackets 20, fixed to the backup wall 12 at the baseplate 28.

[0034] The fastening fingers 32 include a locking portion 36 at an end 38 thereof that extends upwardly from the fingers 32. In a current embodiment, the backup wall bracket 20 includes two fastening fingers 32 each with a locking portion 36 and the locking portions 36 are formed as integrally as upwardly extending lips. The backup wall bracket 20 can include one fastening finger 32 or multiple fastening fingers 32, all configurations of which are with the scope and spirit of the present disclosure. The baseplate 28 can include openings 40 to secure the backup wall bracket 20 to the backup wall 12 and/or structure 10. To facilitate installation, the extension leg 30 includes openings 42 therein for receiving fasteners, such as screws or bolts, as will be described below. As seen in FIG. 3, the fastening fingers 32 have a thickness t.sub.32.

[0035] The adjustable vertical support members 24 are L-shaped members having a mounting leg 44 and a transverse or façade facing leg 46. The façade facing leg 46 can include an inwardly extending return bend 48 opposite the mounting leg 44. The return bend 48 provides structural strength and rigidity to the adjustable vertical support member 24 and serves to hold the insulation in place. As best seen in FIGS. 3 and 4, the adjustable vertical support member 24 includes openings 50 in the mounting leg 44 that correspond with and are configured to receive the fastening fingers 32. In a current embodiment the openings 50 are slotted openings. The slotted openings 50 have a height h.sub.50 slightly larger than a height h.sub.32 of the fastening fingers 32 and have a width w.sub.50 larger than the thickness t.sub.32 of the fastening fingers 32. The adjustable vertical support member 24 is installed on the fastening fingers 32 by positioning the adjustable vertical support member 24 onto the fastening fingers 32, through the slotted openings 50 and lowering the adjustable vertical support member 24 so that the upwardly extending locking portions 36 rest on an inner surface 52 of the mounting leg 44 above the slotted opening 50.

[0036] This configuration of narrower or thinner fastening finger 32 and larger width slotted opening 50 permits adjusting the position of the adjustable vertical support member 24 toward and away from the backup wall 12 or structure 10 as illustrated in FIGS. 3 and 4, in which in FIG. 3, the adjustable vertical support member 24 is at a greatest distance from the backup wall 12 or structure 10 and in FIG. 4 in which the adjustable vertical support member 24 is at a greatest distance from the backup wall 12 or structure 10. It will be appreciated that this novel interlocking configuration permits adjusting the distance between the rainscreen 16 and the backup wall 12 or structure 10 to accommodate different thicknesses of insulation 14 and also permits adjusting the position of the rainscreen 16 to accommodate irregularities in the surface of the backup wall 12 or structure 10.

[0037] In order to affix the position of the adjustable vertical support member 24 to the backup wall bracket 20, the adjustable vertical support member 24 includes a tab or flange 54 on the mounting leg 44 the extends rearwardly (toward the backup wall 12 or structure 10). The height h.sub.54 of the tab 54 extends from about a top of an upper slotted opening 50 to a bottom of an adjacent lower slotted opening 50 as best seen in FIG. 3. The tab 54 is sufficiently deep d.sub.54 so that regardless of where the adjustable vertical support member 24 is positioned away from or toward the backup wall 12 or structure 10 (e.g., as seen in FIGS. 3 and 4), fasteners F can be positioned in the backup wall bracket openings 42 and into the adjustable vertical member tab 54.

[0038] The fixed midspan brackets 22, best seen in FIGS. 1 and 5 include a base plate 56 and an extension leg 58. The fixed midspan brackets 22 can be installed, by fasteners F, to the backup wall 12 or structure 10 and to the adjustable vertical support members 24 once the adjustable vertical support members 24 are fixed in place at the backup wall brackets 20.

[0039] FIG. 5 illustrates the rainscreen support system 18 with multiple adjustable vertical support members 24 and one horizontal support member 26. The horizontal support member 26 extends along all or some of the adjustable vertical support member 24. In an embodiment, the horizontal support members 26 are C-shaped channels. Other suitable structural shapes will be recognized by those skilled in the art. Only one horizontal support member 26 is shown for ease of illustration, but it will be understood that multiple horizontal support members 26 can be used in the system 18.

[0040] To mount the horizontal support members 26 to the adjustable vertical support members 24 such that an outer surface 60 of the horizontal support members 26 are flush or near flush with the transverse or façade facing leg 46 of the adjustable vertical support members 24, the horizontal support members 26 have cut-outs 62 in the legs 64 of the C-shaped channel. In this manner, when the horizontal support members 26 are fastened to the adjustable vertical support members 24, their outermost faces (the outer surface 60 of the horizontal support members 26 and the façade facing leg 46 of the adjustable vertical support members 24) are flush or near flush with one another; in other words, the outer surface 60 of the horizontal support members 26 and the façade facing leg 46 of the adjustable vertical support members 24 can define one or more planes P (see, FIG. 5).

[0041] In a current embodiment, the backup wall and fixed midspan brackets 20, 22 are 12-gauge (ga. thick) stainless steel and the slotted openings 50 in the vertical support members 24 have a width w.sub.50 of about ¾ inch to allow for the depth (in/out) adjustment of the vertical support members 24 and a height h.sub.50 of about 2½ inches. The vertical and horizontal support members 24, 26 are formed from 12 ga. aluminum. The vertical support member tab 54 is about 6½ inches long (h.sub.54) and about 1½ inch deep (d.sub.54) to permit securing the vertical support member 24 to the backup wall bracket 20 at the tab 54. Other bracket 20, 22 and member 24. 26 materials and sizes will be recognized by those skilled in the art and are within the spirit and scope of the present disclosure.

[0042] In the present disclosure, the words “a” or “an” are to be taken to include both the singular and the plural. Conversely, any reference to plural items shall, where appropriate, include the singular. All percentages are percentages by weight, unless otherwise noted.

[0043] All patents and published applications referred to herein are incorporated by reference in their entirety, whether or not specifically done so within the text of this disclosure.

[0044] It will also be appreciated by those skilled in the art that the relative directional terms such as sides, upper, lower, top, bottom, rearward, forward and the like are for explanatory purposes only and are not intended to limit the scope of the disclosure.

[0045] From the foregoing it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present disclosure. It is to be understood that no limitation with respect to the specific embodiments illustrated is intended or should be inferred. The disclosure is intended to cover by the appended claims all such modifications as fall within the scope of the claims.
