Modular panel system particularly for below grade applications

Abstract

A modular wall panel system includes a pair of specially formed receiver strips, base and crown moldings, and a panel. The receiver strips are respectively mounted at selective upper and lower wall locations. Each receiver strip has an elongated base for mounting to the wall, and first and second flanges protruding therefrom, with each flange having a pair of apices particularly formed and located thereon. The crown and base moldings have bottom and rear surfaces, an inward facing ornate/sculpted surface, and a mating flange configured to cantilever away from the rear surface. The mating flange includes a pair of apices that are configured to be mated between the first and second flanges of the receiver strip, and be retained by its flange apices. The receiver strip also spaces the rear surface of the moldings away from the wall/studs, for the panel to be inserted behind the rear surface of each.

DETAILED DESCRIPTION OF THE INVENTION

(44) As used throughout this specification, the word may is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words include, including, and includes mean including but not limited to.

(45) The phrases at least one, one or more, and and/or are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions at least one of A, B and C, one or more of A, B, and C, and A, B, and/or C mean all of the following possible combinations: A alone: or B alone; or C alone: or A and B together; or A and C together; or B and C together; or A, B and C together.

(46) Also, all references (e.g., patents, published patent applications, and non-patent literature) that are cited within this documents are incorporated herein in their entirety by reference.

(47) Furthermore, the described features, advantages, and characteristics of any particular embodiment disclosed in the following specification, may be combined in any suitable manner with any of the other embodiments disclosed herein.

(48) FIG. 1 is a perspective view showing below-grade concrete walls 11, 12, and 13, and a sub-floor 10 of a building, upon which the owner desires to have a finished interior wall surface. FIG. 2 illustrates the walls 11, 12, and 13 of FIG. 1, after a plurality of framing members have been attached thereto, which may be conventional 24 studs, or may instead be 22 strips or even furring strips. Ordinarily, the building's owner would finish the wall through the labor intensive process of fastening plasterboard (i.e., drywall) to the studs using screws or nails, taping and mudding the joints, and mudding all of the fastener heads as well, and then sanding and priming and painting the unfinished drywall. The process is quite messy, as sanding of the mudded portions produces large quantities of dust, which must be cleaned, and the particulates from the sanding process may pose a serious health hazard as a result of inhalation and prolonged exposure.

(49) The present invention is particularly adapted to eliminate the drawbacks of installing conventional drywall, and makes use of unique molding pieces and a panel, which may be supported by a receiver strip, in accordance with the following disclosure.

(50) A first embodiment of a receiver strip 20 in accordance with the present invention is shown in FIGS. 3-4, and may be formed of various different materials, including but not limited to, a rigid PVC (polyvinylchloride). The receiver strip 20 may extend from a first end 21 to a second end 22, and may be formed to include a base 23, from which may protrude a first flange 24 and a second flange 25. In the cross-sectional view of FIG. 4, the flanges 24 and 25 appear to be a pair of prongs, however, each of the flanges 24 and 25 may extend from the base 23 throughout the full length/extent of the strip 20 (i.e., the flanges may be as long as the base), or alternatively the flanges may extend from the base intermittently, or the flanges may extend from the base according to any other desired pattern/frequency, including being spaced at regular or irregular intervals. Merely to be exemplary, the flanges 24 and 25 are shown throughout the figures as extending the full length of the strip 20, from first end 21 to second end 22.

(51) As seen in FIG. 4, each of the flanges 24 and 25 may protrude from the base 23 to a distance P, and each may have a pair of tapered surfaces formed thereon, which face each other. Flange 24 may have a tapered surface 24A that may begin at the free end of the flange (i.e., at height P) and may be at an angle to increase the thickness of the flange. The tapered surface 24A may transition into a second tapered surface 24B, which may be at an angle to taper back to the nominal thickness of the flange, and may thus form an apex 24P.

(52) The flange 25 may similarly have tapered surfaces 25A and 25B formed thereon to create an apex 25P, and these surfaces may generally mirror the tapered surfaces of flange 24.

(53) The tapered surfaces 24A and 25A on flanges 24 and 25 may each preferably be at a fairly shallow angle, and the angle shown in FIG. 4A may be roughly 15-20 degrees. The tapered surfaces 24B and 25B on flanges 24 and 25 may each preferably be at a steeper angle, and angle may even be 90 degrees; however, in one embodiment tapered surfaces 24B and 25B may be oriented for angle to be roughly 55 degrees, which may be sufficient to secure the moldings of the present invention thereto, while also permitting its removal with the application of a reasonable amount of force, as discussed hereinafter. The interior surfaces 241 and 251 of the flanges 24 and 25 may be at a desired distance apart. Also, the tapered surfaces 24A and 25A on flanges 24 and 25 may have a length that in combination with the flange-to-flange distance produces a desired gap G between the apex 24P and apex 25P, which is also discussed hereinafter.

(54) As seen in FIG. 5, a receiver strip 20 may be secured to each of the upper and lower portions of walls 11, 12, and 13, at a select distance away from the ceiling and the subfloor 10. In addition, as seen in FIG. 6, a receiver strip may also be secured to middle portions of walls 11, 12, and 13, if a chair rail molding is desired. If the panel system is to be used on only a single wall of a room, the upper and lower receiver strip 20 may each be cut to be substantially the same length as the wall, being slightly smaller to prevent the strip from being wedged between the adjacent walls. If, as seen in FIG. 5, the panel system is to be used on multiple walls of the room, which would entail paneling/finishing an inside corner, the upper and lower receiver strip 20 may each be cut to be slightly smaller than the length of the wall, and to accommodate the adjacent receiver strips 20 in a miter-type joint, the flanges 24/25 at its ends positioned at the inside corner may also be beveled at a 45 degree angle. Rather than forming a miter joint, the flanges 24/25 at the end of one of the receiver strips may be trimmed shorter than its base, to clear the flanges 24/25 of the adjacent receiver strip.

(55) To be able to produce a finished interior wall, a specially configured molding is used with (i.e., joined to) the receiver strips 20. These specially configured moldings are shown within FIG. 7 through FIG. 31.

(56) FIG. 7 shows a straight base molding 30 of the present invention. FIGS. 8-10 show a base molding 40 formed to finish out an inside corner. FIG. 11 and FIG. 12 each show a straight chair rail molding (50 and 50) in accordance with the present invention. FIGS. 13-15 show a chair rail molding 50A formed to finish out an inside corner. FIGS. 16 and 17 each show a straight casing molding (60 and 60) formed in accordance with the present invention, which may be used for doors. FIG. 18 shows a straight crown molding 70 in accordance with the present invention. FIGS. 19-21 show a crown molding 70A formed to finish out an inside corner. FIGS. 22-24 show another crown molding 70B formed to finish out an inside corner, and having a reduced height. FIG. 25 shows corner molding 80 in accordance with the present invention. FIGS. 26-27 show a window molding 90 and 90 in accordance with the present invention (note the pair of prongs shown therein may be used to receive a piece of 3 mm PVC to produce a finished look in basement window box). FIGS. 28-31 show a window molding 90A formed to finish out an inside corner.

(57) The straight molding sections may be formed of various different materials, including but not limited to, a celuka PVC (Polyvinyl chloride). Also the corner moldings may similarly be formed of various different materials, including but not limited to, ABS plastic.

(58) The base molding of FIGS. 7-7A is discussed in detail, and its flange feature is similarly found on the other moldings shown throughout the other figures. As seen in FIGS. 7-7A, the base molding 30 may extend from a first end 31 to a second end 32, and may have a top surface 33, and a bottom surface 34, which may generally be flat. The base molding 30 may also have a sculpted surface 35 which is intended to face inward into the room, and may be as ornately sculpted as desired, and which may also subsume the top surface, which may be curved. The base molding 30 may also have a substantially flat rear surface 36, from which may protrude a flange 37 of width W, which should be the same as, or slightly smaller than, the gap G of the receiver strip 20, because the flange 37 is configured to mate with the corresponding flanges 24 and 25 of the receiver strip.

(59) The flange 37 may protrude to a length L, which may be the same as, or is more preferably slightly smaller than, the protruding distance P of the flanges 24/25 of the receiver strip 20. The flange 37 may generally be straight, except that the flat top and bottom surfaces 37T and 37B may transition to surfaces 38A and 39A, which taper outwardly and may be configured to match the corresponding surfaces 24B and 25B of the receiver strip 20 (i.e., may be at roughly the same angle). The distance D between the start of the tapered surfaces 38A/39A and the surface 36 may be the same as the distance T for the tapered surfaces 24A/25A shown in FIG. 4 for the receiver 20. To ensure proper engagement between those surfaces, as seen in FIG. 33A, the distance D may be slightly larger than the distance T. The surfaces 38A and 39A may each transition into a second pair of tapered surfaces 38B and 39B, which may be at an angle configured so that they taper towards each other, and may terminate in a radiused corner surface 37C. Alternatively, the tapered surfaces 38A and 39A may transition directly into a curved surface 37C, as seen in FIG. 12. The distance W2, between the apex where surface 38A meets surface 38B and the apex where surface 39A meets surface 39B, should be the same as, or may preferably be slightly smaller than, the desired gap distance G2 between the inside surfaces 241 and 251 of the flanges 24 and 25 of the receiver 20.

(60) It should be noted that the flange 37 and its associated features, when used on a molding formed to finish an inside corner (e.g., FIGS. 8-10, FIGS. 13-15, etc.), may protrude from both vertical members therein, and may terminate before reaching the corner, or may instead, as seen throughout the Figures herein, converge to form a right angle.

(61) FIG. 32 shows a cross-sectional view through the framed concrete wall 11 of FIG. 5, with the receiver strips 20 shown attached at a suitable upper and a lower location. The receiver strips 20 may be secured to the framing members using, for example, framing screws, and may be located using a template, or by measuring to ensure being secured at the proper height. FIG. 32A shows the same cross-sectional view as in FIG. 32, but just prior to respective engagement therewith by a section of crown molding 70 and a section of base molding 20. As may be seen therein, the flange 37 of each of the pieces of molding are configured to be mated with the two flanges of the respective receiver 20. The receiver strip 20 mounted at the upper location may be used to support the end of an adjacent drop ceiling panel. If a drop ceiling panel is not used with the molding and panels of the present invention, a portion of, or all of the upper flange of the base 23 of the receiver 20 may be scored and snapped off, so that the receiver strip may be properly positioned with respect to the ceiling.

(62) FIG. 33 shows the cross-sectional view of FIG. 32, after the respective flanges 37 of the sections of crown molding 70 and base molding 20 have been inserted into the flanges of the respective receiver strips.

(63) At this point in the installation, the framing members attached to the concrete walls are still not covered. However, FIG. 34 is the same cross-sectional view of FIG. 33, but also shows a panel 100 of the present invention with its upper end 100U initially being inserted behind the crown molding 70. Different panel materials may be used, but in one embodiment the panel used for the present invention, as shown in detail in FIGS. 34A-34C, may be a composite panel that may include a three mm thick Magnesium Oxide board 100MB, a one mm PVC backing sheet 100PV, and sandwiched therebetween may be a closed cell Polyisocyanurate foam 100F, which may have a fire retardant built into it. The magnesium oxide board 100MB may serve as sheathing, as a drywall replacement, and offers improved characteristics including tire, mold, and mildew resistance, and greater strength. These composite panels may be cut as required using a skill saw or jig saw with a downward blade.

(64) To ensure that the top corner of the panel 100 does not get caught by, or hung up on, the corner of the base 23 of receiver 20, the top of the panel may be radiused or chamfered, and/or the lower corner of the base 23 of receiver 20 may also taper down to a substantially small thickness (i.e., 0.010 inches) or may even taper down into a knife edge.

(65) FIG. 35 shows the upper end 100U of the panel 100 fully inserted behind the crown molding 70, and with the panel generally parallel with the wall 11 and with its lower end 100L positioned above the base molding 30.

(66) FIG. 36 shows the panel 100 after it has been lowered, for its bottom portion 100L to be nested behind the base molding 30 in contact with the upper flange of the receiver strip 20, to produce the finished wall section.

(67) For the panel 100 to be able to cover the exposed wall 11, the height H of the panel should be greater than the opening V between the bottom of the crown molding 70 and the top of the base molding 30, as shown in FIG. 36. Also, to be able to slide the bottom 100L of panel 100 over the top of the base molding 30, as seen in FIGS. 35 and 36, the height H of the panel 100 should be smaller than the distance V1 between the top of the base molding 30 and the bottom-most flange of the receiver strip 20 mounted at the upper wall location, and also, the distance V3 from the bottom of the crown molding 70 to the lower flange of the upper receiver strip 20 should be greater than the distance V2 between top of the base molding 30 and the upper flange of the lower receiver strip 20 (i.e., V3>V2).

(68) Multiple panel sections may be needed to laterally cover the full extent of a wall, and any vertically oriented panel-to-panel joint may be concealed using a floor-to-ceiling trim piece that may be secured to one or both of the panels at the joint using for example, but not limited to, adhesive, nails, screws, etc.

(69) Where a chair rail molding is utilized, two separate panels would similarly be installed to complete the finished wall. Typical panel sizes would be a 6448 top panel and a 3248 bottom panel. The receiver strip 20 for the chair rail may thus be appropriately positioned to accommodate those standard panel sizes.

(70) The disclosed arrangement permits easy access behind the wall panels, if necessary to effect repairs to electrical wiring, or to add wiring, etc., simply by removing the panel in a reverse manner (i.e., by raising the panel 100, by angling its lower end 100L outwardly, and by next removing the upper end of the panel 100U from behind the crown molding 70). The moldings may also be readily removed, if necessary, particularly where a non-ninety-degree angle is used for the surfaces 24B and 25B on the receiver strips 20, which may help facilitate the outward deflection of the flanges 24 and 25 needed to dislodge the flange 37.

(71) It should also be noted that the disclosed arrangement may similarly be utilized for the above-grade finishing of a framed room, rather than using drywall.

(72) Additionally, in an alternate embodiment, the receiver strips 20 may be mounted directly to a concrete wall without any wood framing, using concrete nails. In this embodiment, the PVC backing 100PV of the panel 100, being a strong but light-weight plastic, may be suitably positioned to face the rough concrete.

(73) The examples and descriptions provided merely illustrate a preferred embodiment of the present invention. Those skilled in the art and having the benefit of the present disclosure will appreciate that further embodiments may be implemented with various changes within the scope of the present invention. Other modifications, substitutions, omissions and changes may be made in the design, size, materials used or proportions, operating conditions, assembly sequence, or arrangement or positioning of elements and members of the preferred embodiment without departing from the spirit of this invention.
