1. Field of the Invention
The present invention discloses a kit, assembly, and installation process with hardware used for securing and aligning wall panels into a functional and decorative array of arranged panels. The inventive panel system combines unique attachment mechanisms, layout, panel joinery, and accommodation for building movement. Further, the system provides several unique means for securing the system panels within a system framework, and for supporting the weight of each panel in such a manner that thermal coefficient's of expansion/contraction which are endemic to given installation environments will not otherwise result in warping or buckling of the panels at their mounting interfaces. 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 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 superior ability to absorb building movement including a unique provision for individual panel movement to not affect or transfer any stress or movement to any other panel within the same arrayed installation.
The inventive panel system also allows for the option of accommodation for building movement while providing for simultaneous stable panel bearing support, and the option for system framework to remain in contact and alignment with all four sides of an installed panel, or alternatively (depending on the need parameters of the installation) the fourth (top) panel edge is adjacent a headspace of at least 1/32″ and as much as ¼″, providing room for an unbalanced, unconditioned, or unstable panel to safely expand without disturbing other elements of the installed array of panels (see plastic spacer detail). 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 vibration, moisture, or humidity. Additionally, the present system avoids the requirement for drilling or otherwise machining the back side of the wall 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 thicker than ¼″, and are most commonly 5/16″ to ¾″ 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, 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 is 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 an improved panel system and installation process which uniquely maintains panel contact on all four edges of its perimeter while simultaneously maintaining full planar bearing 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. Panel edges may preferably be engaged at a 135° angle between the direction of the panel and the resistive force of the inventive molding, or without any resistive force by way of the panel headspace allowance included between the molding's splines and at the top and/or one side edge of the panel by use of a plastic spacer within the inventive molding. A further distinguishing feature of the inventive system is that the various supporting profiles engage the panels upon their outside edge corners or perimeter faces, and as opposed to by the panel ends as is accomplished in all prior art systems, the effect of such an engagement feature being a compressive force which does not pull the panel apart, rather it acts to keep the panel together while under stress, or elimination of the stress altogether at the option of the user.
Additional variants associated with the present assembly include providing for individually demountable panels while using inexpensive reclosable fasteners which are individually mounted such as be reverse face adhesive strips to each of inner faces of the panels and opposing outer faces of the surface mounted profile extrusions or other configurations, this in combination with the unique shaping of the profiles providing mounting of one side of the reclosable fastener, with additional vertically-oriented profiles establishing aligning contact with additional mounted panels along each adjacent side. The reveal profile is provided according to a variety of different designs and maintains contact along each vertical edge of each panel, even during movement of the panel or installation.
Demountable panels are also suspended in full bearing support along their bottom edge, such as through the installation of an additional elongated profile exhibiting a lip support lower edge which extends proximate a floor location. Demountable installations exhibiting multiple (two or more) rows of panels can feature a horizontal profile adjacent to the top running edges of panels.
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.
The numerous examples of the panel supporting and vertical/horizontal intersecting profiles and also include each of a vertical profile supported upon a vertically-oriented dual seam strip. The dual seam strip can be designed to include two columns of reclosable fasteners along its length, with each column corresponding to a panel supported adjacent to the molding's left and right.
Additional features can include the reclosable fasteners being flexible (or movable) in at least two, and preferably each of three (xyz) dimensions concurrent with expanding/contracting movement of the supported panels. This is further accomplished in such a way as to maintain edge spacing between the multiple panels. The material construction of the various reveal profiles can also include, without limitation, such as aluminum or other thin walled materials which provide a desired combination of support and, where necessary, some dynamic deflection or give. Variant of the profile constructions, such as including the reclosable profiles described herein, can also be constructed of a rigid plastic or composite material.
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 interior 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 contract, 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 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 reclosable assemblies, the latter permitting individual panels to be demounted from the wall assembly 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, the multiple supported rows of panels not touching the floor and, as such, capable of being employed up a wall's height to any desired top end.

A plurality of joists or studs are provided arranged in a manner for supporting the sub wall 16, such as which are depicted at 18 in each of
Given the above description, the present assembly includes the assembly of a plurality of profile components in a number of grid defining configurations in order to securely and dynamically support the edges of the panels 12, 14, et seq. As shown in
The double panel profile shown exhibits any elongated or height extending direction (as best shown in
As described, opposing pluralities of reclosable fasteners are provided for mounting the inner faces of the panels 12 and 14 to opposing and supporting surfaces established by the wing portions 24 and 26 of the double panel supporting profile. In one non-limited application, these fasteners (see as depicted by a first pair 36 & 38 secured to outer facing surfaces of the wing portions 24 and 26, as well as a second pair 40 & 42 secured to inner facing and aligning surfaces of the panels 12 and 14) can include a commercial product produced by 3M® under the technical name Dual Lock™ Reclosable Fastener.
The Dual Lock™ fastener system typically includes an elongated strip exhibiting a peel away adhesive backing for securing lengths thereof to any of vertical and/or horizontal extending locations of the profiles and panels.

Without limitation other fastener constructions, such as variations of hook and loop fasteners or the like, can be augmented or substituted for those shown at 36-42 and without departing from the scope of the invention. These can further include other reclosable fastener systems such as hook and loop and interlocking stem and interlocking island systems such as known under the commercial names Lynx™ and QwikGrip™, and the like.

Owing to the secure and multi-dimensional floating engagement afforded by the opposing pairs of fasteners 36 & 38 and 40 & 42, the inner panel edges bias and sandwich the vertically extending component 50 in a manner which retains the component 50 in contact with the exterior of the dual profile 20, while permitting the panels 12 and 14 a limited degree of independent or concurrent multi-axial motion in a manner which does not introduce any strain or deformation, while also permitting the inner panel edges to move along the sloped profile edges 56 and 58 of the sandwiched component 50.
A floor proximate extending support profile is provided as shown at 60 in

The profile 86 exhibits a number of features similar to that associated with the floor profile 60 and includes an arrangement of support feet 88 and 90 for leveling against the sub wall 16 upon installation of fasteners 92 through apertures defined in the profile. A reclosable fastener 94 as previously described is adhesively attached to the exterior face of the profile in a similar fashion as previously described and so that an opposing (inner) facing reclosable fastener (see at 96 in

As further shown, the panels 200 and 202 exhibit inwardly stepped edges (see at 204/206 for panel 200 and further at 208/210 for panel 202). A cushioning strip 184 as previously described can be secured to an inner facing surface of a selected outermost lip 198 and, in combination inner spaced protuberances 212 and 214 exhibited on the lip 198, provide for thermal coefficient of expansion induced lateral and in/out movement of the panel profile according to multi-axial directions. It is noteworthy that a variety of edge configured panels can be utilized with like variations in the design of the profile (154 or 190) in order to seat the panels in a desired multi-axial displacement permitting fashion.
Proceeding to
Yet additional profiles are shown in each of
Given the above reference descriptions, a variety of different installation protocols and notes as to specific features are presented as follows and which are intended to augment and further clarify the above detailed descriptions as applicable to either or both the replaceable panel configuration of
The dual seam strips, which feature two columns of reclosable zero-liftoff fasteners, may be cut down their center to make two single-row moldings. With the two major aluminum mounting components installed, the system is nearly ready for final install. The decorative and aligning reveal profiles are then placed on the seam strip and secured with a small amount of silicone. The aligning component of the reveal profile is the raised center rib or “hat” which helps the installer gauge the horizontal space between panels. The reveal profile also aids in extra-system lateral load transfer to the sub wall in that any outside lateral load applied to an installed panel face will then transfer to the reveal profile as the reveal profile contacts the rear face of the panel adjacent to each long edge of the reveal profile and through the dual seam strip below and into the sub wall structure.
In this manner, the first wall panel is placed at one end of the wall and aligned up along one edge with the spline. The next panel is aligned along the other side of the spline and also detachably mounted with the re-closable fasteners to the seam support. When the wall is covered with installed panels, a crown molding may be screwed though the top edge of the wall panels. Also along the top edge of wall panels is either a single seam strip run horizontally so as to stabilize and help secure the panels, or a Multi-Row Support Molding or Reveal Molding for the same purpose.
The multi-row support molding features an upper flange which is designed to be exposed. The reveal extrusion also features a central raised section that is designed to be exposed. Both exposed sections' exposed faces are no more 0.035″ proud of the rear face of the installed panel so that the panel, during a time of expansion, may expand and partly overlap the exposed section of the adjacent molding without creating or transferring any stress to an adjacent panel.
A panel system can also be provided which exhibits 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. A divider molding is inset on top of an aluminum seam strip. The upper width of the spline features flexible elements such that it can accommodate building movement such that rigid wall panels will not be exposed to undo stress or buckling forces while still maintaining contact with the panel edge on either side of it.
Also desirous is that there be a flexible element, such as a plastic pad between the rear face of each panel and the aluminum extrusion it is mounted to so that the panel will ideally yield slightly 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. The 3M® Dual Lock® fastener comprises the flexible pad and the reclosable fastener in one component, but the two components may 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, also mounted with a flexible plastic or rubber pad mounted to at least one side.
All screws and mounting hardware are concealed within the finished base and/or crown moldings (such as depicted in the example of
The zero lift-off reclosable fasteners are adhesively bonded to the aluminum support and seam strip pieces and to the backside of the decorative wall panels supported by this system. Without further limitation, the panel constructions as set forth in the aforementioned description may include, but are not limited to each of Phenolic, wood, plywood, MDF, Gypsum, MgO, concrete fiber, agri-fiber, and the like.
The reclosable fasteners are further understood to be oriented ninety degrees from one another (see again as specifically shown in
The grid defining and aluminum profile framework as described above is secured to the sub wall or other surface structure via screws penetrating into the wall structure behind the sheetrock. Nearly any decorative surface or material may be used between the panels (such as within the typical 4-8 mm wide reveal, which may be from 1 mm to 16 mm wide overall). This can further include the use of brushed stainless steel, copper, aluminum, with decorative finishes applied to the reveal molding itself or an insert therein. The reveal molding being separate from the seam strip molding provides a simpler task of coloring any reveal (such as shown at 50 in
The various examples of system moldings and panels again feature a series of interconnecting and engaging surfaces. Whether the panel edge is non-machined, rabbet-edge machined, or two-spline (dado) machined, each serves to locate each panel within the system and provide for some (if not necessarily all) allowance for movement in any combination of multi-axial directions as facilitated by the moldings and profile constructions. This in particular can be reflected in panel movement while acting upon the panel's outside corners and not upon the ends, such as known in prior art systems.
Each molding's second (middle) spline also serves to support the panel back side against lateral loads that may be applied to the system from outside forces such as a grab rail, or wall impact, etc. As such no load outside of the panels themselves, whether transverse or in line with the panel, can ever impart any load into a dado to cause it to split or fracture.
The only movement near any panel dado is the flexing of one panel spline around the “bead” of each molding and that load and movement is carefully directed at an angle of 100-170 degrees (135+/−35) between the panel and the molding and is never 180 degrees. Such an angle is facilitated by either a convex curvilinear surface or an angled ramp or wedge-shaped surface between the two splines along the long edge of a molding. This includes a panel system intended for panels typically from 6 mm (¼″)-12 mm (½″) thick solid phenolic, solid plastic, aluminum honeycomb, up to ¾″ MgO, or MDF panel material, and a ¼″-⅜″ (ideally 5/16″) deep spline to be securely set into the 5/16″-½″ (ideally ⅜″) wide section of each panel's perimeter (or at least two edges thereof), with the lower edge of the panel bearing 100% of its weight onto the supporting molding directly below each panel containing the spline along that panels bottom edge.
It should be further noted that none of the panel's weight is focused into the panel dado or rabbet so the panel is not under any stress to split or crack. Various sections of the splines can also feature a bead-shaped detail contacting the panel perimeter functioning to allow for movement as the panel expands and contracts with environmental changes and/or building movement while still maintaining contact with the panel's edges. This can be a double bead contacting both the front and rear splines of the panel or, alternatively, can be exhibited by a single bead contacting against the panel's rear spline only.
In each of the afore-mentioned variants, all screws and mounting hardware are concealed behind the visible moldings (e.g. see again at 50 in
The inventive moldings are oriented around the perimeter of the orthogonal panels so as to engage all four of the panel edges while applying some compression forces to at least a portion of three of the edges of each panel to make a secure retention of each panel. Each panel's bottom edge also has a spline, but that edge does not flex around any bead and bears the 100% of panel's weight on its spline.
With the moldings securing against the panels via a compressive force (as opposed to a tensile force as in all prior art systems), the use of mineral-based substrates such as gypsum and cement boards such as Portland cement and magnesia cement-based panels become viable. This feature allows such a system to compete directly against finished-in-place drywall (and other mineral-based panel-based) systems which are prevalent in construction today. A reason for this is that mineral panels are not stable in tensile across their thickness, but only in compression.
In one exemplary system, each vertical engagement is configured so that the molding is just touching the corresponding panel's exterior edge (not panel end) at a 135° angle. As a result, any panel movement causes a corresponding minor opening, closing and/or flexing of a corresponding section of the molding's two splines upon or the panel's spline, and such contact occurs along the panel's exterior edges.
The top (horizontal) edge of each panel supplies 100% of the vertical allowance of expansion and contraction, which may vary depending on the height of the panel. For this reason, the reclosable variant of the present system may be used to allow for greater room for expansion.
Additionally or alternatively, greater vertical clearance may also be allowed for by eliminating the bead of the upper panel and using the inter-spline clearance as space for the panel to move. Setting this revised Horizontal Reveal in place is referenced by either a reference line machined into the molding or via a flexible plastic spacer set on or adjacent to the top edge of the panel prior to engaging such as a horizontal extending reveal or molding.
As in all of the inter-related variants of the fixed and removable panel embodiments of the inventive system, the aluminum framework is secured to the structure via screws penetrating into the wall structure behind the sheetrock, and possibly a small amount of adhesive. In the reclosable variant of the inventive system (
The splined variant of the inventive panel system uses very few simple components to provide performance and benefits beyond that of what is available from the very complex prior art systems today. The system can include, in one non-limiting application, a plurality of up to five moldings (horizontal reveal, vertical reveal, inside corner, outside corner, starter), with the horizontal reveal molding being the only mandatory component. The horizontal reveal, in it's headspace-allowance variant form may be used to replace both the vertical reveal and separate horizontal reveal moldings as depicted.
The panels of the inventive system further do not require that they be drilled or fabricated on the rear face which alleviates the requirement of flipping and re-orienting the panels in a CNC machine (or subsequent multiple operations with a shaping tool) and, with only one component (molding) at each location, there is no requirement to reference one component's location against the other within the system. In this manner, installation is greatly simplified and makes the system truly field fabricatable and install-able by non-specialized, local workers.
Other considerations include the inventive system variant flexing outside of any cut or machining of the panel edges, such that it maintains constant contact via a safe and stable compressive force upon the perimeter edges even during movement. Further still, the present system provides additional lateral support against loads imparted to the panel by means outside of the dado or machined panel perimeter, wherein the panel is at full thickness, full strength, and has no crack starters or cuts into it.
It is again notable that the present system primarily engages the panel edges and not on their ends. By engaging the panels at their edges and not on any panel end (except for the lower panel edge for bearing as depicted by example in
In this manner, a lineal engagement is focused at an angle of typically 135°±/−25°, and is generally not less than 120°, and generally not more than 150°, but may be as much as 170°, and as little as 100°. By deflecting the forces from movement into the interior face of the rear spline of the inventive moldings (90°/lateral orientation from the plane of the panel installation), the resultant and inevitable forces of expansion are not allowed to accumulate from panel-to-panel, as they would via a typical prior art system featuring 180° engagement.
It has been found that this non-lineal angled engagement is an important point since the panel's bearing is focused across an area (and not in lineal fashion) so the panel's forces are not additive from one panel to the other, and so the location of each panel remains substantially constant and the panel only moves as it swells or shrinks with changes in ambient moisture or temperature or as the building itself moves, along the three non-load bearing edges. This uniquely creates a moving panel with a constant location that accommodates such movement within that location. It is also noteworthy that the present system also does not require the panels to be secured by some secondary means to preclude them from wandering out of place along the wall.
By obviating the need for an adhesive bed to retain the panels, as with most C.E.G. installations, the present system eliminates many of the extraneous components associated with the prior art. The present system is also stock-able at multiple locations which can be sold directly to the persons performing the work, thereby reducing cost, lead times, and the necessity for jet and truck travel around the country to perform installations.
Further still, the panels that are to be retained into the system do not have to be shipped to a common location with the moldings so that they can be fabricated and referenced against one another and then re-shipped to the job site. This saves significant travel, and the cost and environmental impacts therefrom.
It has also been found that the present system is very forgiving during the installation process and can be designed so that the panels arrive from the original location, with the hardware being shipped in separately, thereby reducing logistics requirements from multiple shipping of the typically very heavy and bulky wall panel materials. It should also be noted that the combination of the elimination of the double shipping of the panels and the elimination for the need of a special crew to travel across the country to perform the installation greatly reduces the carbon emissions associated with this system.
A final variation in use of the splined variant of the inventive system is that is can be mounted directly to the building subwall studs, obviating the need for drywall sheathing—saving much time and cost in commercial or residential construction. In such an application, a plurality of up to four studs are engaged by every four foot wide panel, with the first and fourth studs receiving an inventive splined molding screw-attached directly to them, and the middle two studs (studs two and three) being first covered by a batten so that may serve either or both of two purposes: to space the panel in parallel fashion equal with the two splined moldings, and to spread any applied lateral forces from the wall panel across a wider surface area by the battens typically being about 6″ wide rather than the stud faces being only 1.5″ wide. Lastly, this system is applicable in a single panel row usage, and in which the panel weight is supported by an integral base molding which may be made of composite concrete fiber, wood or plywood, plastic, or other equivalent material.
Having described my invention, other and additional preferred embodiments will become apparent to those skilled in the art to which is pertains and without deviating from the scope of the appended claims.
