1. Field of the Invention
The present invention discloses a system, kit assembly, and installation process for securing and aligning panels in spaced fashion relative to a wall surface. A profile attachment scheme is established between elongated rails, which are secured to the wall surface, with additional (typically sectioned lengths of rails) clips having identical profiles screwed or otherwise attached to the rear surfaces of a plurality of panels prior to engaging the rails. In this fashion, the clips inter-engage the rails in an opposing and horizontally lengthwise extending and supporting manner so that panels can be either fixedly or individually removable relative to the wall surface.
The present inventions additionally provide an array of features, including unique attachment mechanisms for transferring and distributing both stresses and panel weight across a wider surface area of each panel. Further, the system provides several unique means for securing panels in a variety of ways depending on the installation requirements, such including the panels being supported in such a manner that their thermal coefficient of expansion/contraction (such being endemic to given installation environments) will not otherwise result in warping or buckling of the panels at their mounting interfaces or causing any undesired movement or stress accumulation within the completed installation.
The various configurations depicted herein also provide a maximum of air circulation behind the panels and which assist in avoiding mold or other environmental degradation. The system, kit and assembly additionally offers unique advantages over the prior art including faster installation time, drastically reduced parts count and inventory requirement, the option of individually demounting installed panels, faster and simpler alignment of panels over uneven walls, sound absorption of both high and low frequency noise, interchangeability of decorative moldings, reduced materials cost, reduced installation cost, and drastically superior ability to absorb building movement including a unique provision for individual panel demounting.
The inventive panel bracket and system also allows for the option of accommodation for building movement while providing for simultaneous stable panel bearing support without disturbing other elements of the installed array of panels. Movement of architectural components occurs either during normal seasonal movement of the building, or in the natural expansion and contraction of the panels themselves by varying conditions of temperature, vibration, moisture, or humidity. Additionally, the present system avoids the requirement for machining the edges of the panels and provides several different mounting methods within the same system, while maintaining a unique mix of features and benefits not previously known in the art.
2. Background of the Relevant Art
Architectural panels are well-known in the art. Such panels differ from most wall coverings in that they typically feature mechanical attachment of some sort, or at the very least offer a thickness exceeding typical wallpaper-type coverings and are therefore generally ¼″ thick or greater, and are most commonly 5/16″, ⅜″, ½″ and up to 1″ in thickness.
Such panel systems are typically employed to conceal building wall irregularities and to protect and decorate wall surfaces in offices, hospitals, retail spaces, and building interiors. The panels are most commonly offered in wood grain, metallic, simulated grass, and other faux finishes. Substrate materials are most commonly plywood, wood flour, solid phenolic composite, gypsum or other mineral (e.g. magnesium oxide, Portland cement) board, plastic, or combinations thereof.
Additional examples from the prior art include the panel attachment systems depicted in each of U.S. Pat. Nos. 6,427,408, 8,151,533 and 6,202,377, all to Krieger. In the Krieger, '533 reference, a modular wall system includes a number of decorative panels that are received in an extruded panel frame. Each of the frames are positioned by connecting them to a wall rail that is attached to the building. The wall rail and panel frame each have a groove that accepts a fastener or clip by interference or snap fit to attach the panel frame to the wall rail. The grooves have a dove-tail shape that permits a snap fit to secure the panels, while permitting the panels to be easily removed or reconfigured.
In each of the Krieger '408 and '377 references, the wall system includes a plurality of rectangular rigid prefinished panels mounted on a wall support structure with main runners and cross runners. The main runners serve to lock the panels onto the support structure and with the cross runners serving to prevent the wood-based panels from warping due to adverse moisture conditions. The main runners are configured to space the panels from the wall support structure to encourage uniform humidity conditions at the front and rear of the panels. Clips that secure the panels to the main runners are fixed adjacent the top and bottom panel edges at different setoffs to obtain an advantageous nesting of panels for reduced packaging volume.
The present invention discloses a mounting bracket, provided as identically cross sectional shaped and sub-wall mounted rails and panel reverse face mounted clips, and which is incorporated into an improved panel mounting system and installation process which uniquely allows individual panel demount ability and focuses panel weights towards the structural support of the wall surface, the while simultaneously maintaining suspension of the panel weight and for allowing the panels to individually expand or contract, such as according to a given coefficient of thermal expansion associated with the panel being situated within a given environment. Without limitation, the panel edges may be engaged at any of a variety of angles.
A further distinguishing feature of the present system is that a non-horizontal orientation of the two bearing surfaces of the bracket, such as defined by ramped engaging surfaces established between a pair of nesting “U” shaped portions associated with the rail and clip. The typical angle of the two bearing surfaces is 10° (downward relative to a horizontal and and toward the sub-wall), but can be any angle not limited to one desired range of between 5° to 20.
Additional variants associated with the present assembly include providing for individually demountable panels while using inexpensive reclosable fasteners such as 3M Dual Lock or Velcro and other reclosable fasteners, which are individually mounted as adhesive strips to each of inner faces of the panels and opposing outer faces of surface mounted profile extrusions which are screw-attached to the sub wall. Such plastic Velcro and friction-type reclosable fasteners can be without limitation employed along the lower and/or side edges of each panel, with the nesting rail and clip utilized along upper extending locations of the mounted panel. A further variation envisions the use of rubber isolated batten strips filling in a center field between a pair of panels in a cost-effective installation with damping for high and low frequency vibrations (see co-pending application).
Individually demountable panels may also be suspended in the main field if each panel with the clip and rail components engaged in single or multiple rows. Further each row may face the same direction or the uppermost row may face in the opposite direction thereby locking the panel in place and precluding it from being demounted until it is unlocked.
Any of the profile configurations depicted herein can also exhibit at least one surface which is either flush with or spaced a distance from a sub-wall surface of the room (this defined as such as the underlying wallboard or drywall material covering the joists and to which the decorative panel assembly is mounted). In given applications, a sub-wall separation distance of a panel supporting profile can be less than an additional distance that may be accommodated by a reclosable fastener without disengaging therefrom. Additional features can include the inventive bracket (rail and clip) being used in combination with any of the prior disclosure materials.
Reference will now be made to the attached drawings, when read in combination with the following detailed description, wherein like reference numerals refer to like parts throughout the several views, and in which:
With reference to the succeeding illustrations, the panel system and kit according to the several embodiments described herein provides bearing support for a plurality of panels assembled in a decorative supported array upon a wall and in such a way that the panels are permitted to expand or contract according to their determined thermal coefficient, such as resulting from a given set of environmental conditions. As is also known, extended running lengths of assembled panels and the underlying grid configured profiles required for mounting the panels can multiply the degree of expansion or contraction, such as varying in intensity or degree over a significant time elapse not limited to changing of seasons, with the result being that an anticipated set of dimensional changes not anticipated for in the original installation can result in warpage, panel expansion, buckling panel cracking, delamination, or inadvertent disengagement of the panels from the underlying support structure.
As will be further described below, the present invention provides each of fixed and individually demountable panel assemblies, the latter permitting individual panels to be demounted from the wall assembly at any time without interfering with the remaining panel installation. Additional features of the present system and assembly include the ability to bear all a given panel weight within a very small area of the panel, combining the inventive bracket with reclosable fasteners or other high coefficient of friction plastics or rubbers to additionally secure each panel from accidental demounting, combining the inventive bracket with battens in the main field to allow airflow and reduce overall cost and dampen vibrations, and combing the inventive bracket with the various trim components of the prior co-pending systems for reveal, corner, and edge trims.
The above said, and referring initially to
A feature of the invention is the provision of a plurality of inter-engaging or inter-supporting brackets, these initially depicted by rails 8 (also

A connecting web 22 of the “U” shaped profile extends upwardly from a midpoint of the inner ledge 18 and likewise includes a centerline 24 establishing a perpendicular with the inner ledge centerline 18 (and by extension a parallel with the surfaces 12/14 of the main body. An outer ledge 26 is provided and includes a slightly outwardly angled profile relative to the inner ledge 18, this best depicted by inner and outer tapered surfaces 28 and 30 which are reflected by surface axes which extend at angle (such as 10°) relative to a horizontal line 32 (parallel to line 20) taken through a central location of the outer ledge 26. Additional features associated with the rail include such as “V” notched drill lines 34 and 36, this in order to facilitate application of mounting fasteners (see further at 38 and 40 in
To facilitate this mounting arrangement, mounting apertures can also be defined in the clips 10, see inner perimeter rim surfaces 54 and 56, such as coinciding in location with a selected one 52 of the “V” shaped recess notches. Notch indicating locations, at 58 and 60, are also referenced on the exposed surface 38 of the clip 10 and provide an optional feature for facilitating use of the mounting assembly in a reverse locking configuration as will be subsequently described.
Additional to providing a plurality of individually pre-sized clips (such as which may be pre-attached to the reverse face of a suitable plurality of panels in a desired mounting application) it is also envisioned that a plurality of rails 8 can be shipped (such as again shown in
In combination with the reclosable portions 62 and 64, the elongated profile 66 depicted in

In this variant shown, the flexible element integrated into each panel 6 can include such as a plastic pad between the rear face of each panel and the aluminum extrusion (e.g. clip 10) it is mounted to so that the panel will ideally yield slightly (e.g. again at 6′) when an outside transverse load is applied to the panel and to further facilitate panel movement without stress such as when a panel may expand and partially overlap an adjacent exposed face of an extrusion.
As also previously described, the 3M® Dual Lock® fasteners (102 and 104) each incorporate a flexible pad and reclosable fastener in one formed component. It is also understood that the desired reclosability can be achieved separately such as with conventional hook and loop fasteners, with one side mounted to a flexible strip of plastic, or by using rare earth magnets, which are easily found with sufficient strength, and which may also be mounted with a flexible plastic or rubber pad mounted to at least one opposing side established between the sub-wall and panels.

Installation of the panel 108 can also be accomplished by sliding laterally so that the “U” shaped portions 146 and 150 of the upper and intermediate tiered clips engage the seating profile surfaces of the rail mounted “U” shaped portions 144 and 148. Also, and by exposing an uppermost fastener (at 152) of the top tier affixed rail 8, removal of this fastener can facilitate lift-off demount-ability of the panel 108. As is further understood, the top tier arrangement of clip and rail can also be reconfigured in a clip to clip engagement in order to permanently secure the panel 108 to the sub-wall 4. The lower panel 110, while also being shown in reduced height, can also incorporate a middle tiered rail to clip mounting configuration (not shown but oriented in the fashion depicted by the uppermost tier of rail and clip) and which is located at a position above the floor located “J” profile 116.
Viewing the several depicted variants, it is easily understood and envisioned that the tiered panels are capable of being mounted according to several variants. Given the above description, the present system and assembly encompasses a variety of mounting applications in which a plurality of profile components are arranged in a number of grid defining configurations in order to securely and dynamically support each panel from its rear face. A double panel profile mounting variant as further illustrated and described herein can exhibit any elongated or height extending direction. Other and additional mounting arrangements contemplate mounting the panels to a horizontally or angularly extending ceiling surface as well as a vertically extending wall surface as depicted.
Non-limiting variants of the panels can also exhibit 6.3 mm thick magnesium oxide board substrates, and flame-resistant polyolefin faux veneers covering the substrate, and a 4 mm flexible spline set between panels to create a vertical reveal between the panels. Additional accessories (not shown) can include divider molding can also be inset on top of an aluminum seam strip. The upper width of a spline feature can exhibit flexible elements, such that it can accommodate building movement and, in this fashion, the rigidly supported wall panels will not be exposed to undo stress or buckling forces, and while still maintaining contact, on either side, with the associated edges of the panels being supported.
Depending upon the mounting application, all screws and mounting hardware are usually concealed within the airspace (or gap) between the inside surface 7 of the panels 6 and the exposed surface of the sub-wall 4, it further being noted that, with the inventive rail and clip configuration, no exposed fasteners are necessary. The ultra-low lift-off design of the inventive bracket additionally permits the individually demountable feature of the panels and also greatly eases the installation proves of each panel, especially in combination with the 10° throat or angle as representatively depicted in
Any reclosable fasteners can also be oriented ninety degrees from one another so as to maximize the alignment flexibility, while maintaining a constant surface area of engagement between the associated panel (such as previously at 110 in
The panels are secured against the sub-wall 4, such that a mild compressive force as created by the 10° angular and ramped relationship between the bearing surfaces of the rail and clip (again as shown by surfaces 78/82 and 80/84 in
Other non-limiting features include the provision of phenolic fasteners for fastening the clips to the inside surfaces of the panels. The panels can also be formed or coated with a high-pressure phenolic material, and in which thread-cutting screws do not penetrate the panel's face and are therefore not visible in the completed installation. It is another feature of the present invention that any such fasteners used with the panels have a major diameter at least 0.020″ and preferably 0.030″ to 0.050″ less than the interior diameter of the holes in the Clip assembly. This is of particular use as shown in
Additional aspects of the present invention include a degree of forgiveness in the installation process (by virtue of the misalignment accommodating gaps and spacing built into the design of the rail and clip brackets as previously described) and can be designed so that the panels arrive from the original location, with the hardware being shipped separately, thereby reducing logistics requirements from multiple shipping of the typically very heavy and bulky wall panel materials.
According to one non-limiting mounting arrangement, a standard ¼″ (6.4 mm) panel headspace allowance incorporated into typical installation layouts allows sufficient clearance for the low-profile design of the inventive bracket for a panel to individually demount from the wall surface. It is also understood that any scale or dimension can be employed in the configuration or sizing of the rails and clips, as well as any suitable combination of mounting hardware being provided within the scope of the invention, such as ranging from a single rail and clip provided for securing each panel to an associated wall surface location, ranging to multiple tiers of nesting or inter-engaging rails and clips provided between the wall surface and panels and arranged for either demounting or affixing the panel to the wall. The present invention further envisions any combination of additional accessories provided in combination with any one or more pair of nesting rails and clip, and again not limited to the intermediate extending wall support profiles shown in
