1. Field of the Invention
The present invention is related to modular wall assembly systems for the construction industry. More particularly, the present invention relates to modular wall assembly systems comprising a metal frame and replaceable wall modules such as wall panel units, bookshelf units, or cabinets for mounting on said frame.
2. Description of Related Art
Wood frames for assembly of walls have been the conventional choice of builders, and modular wall framing systems made of wood, such as the system described, in U.S. Pat. No, 4,281,491 are known, which patent hereby incorporated by reference herein in its entirety. Wood, however, can often change shape or fragment over time through buckling, warping, or splitting and is not fireproof. Metal presents an attractive alternative to wood because it lacks these disadvantages and is also cheaper and lighter.
With respect to the home, it is often desirable to remodel or redecorate such as changing the decor of a wall, replacing cabinets, or adding a bookshelf or entertainment center. However, such remodeling projects are often costly, time-consuming, messy, and disruptive for the homeowner. U.S. Pat. No. 7,987,648 discloses a modular wall panel system that allows, for placement and replacement of decorative panels, which patent is hereby incorporated by reference herein in its entirety. The system relies on a skeletal frame attached to an existing wall surface, but is not compatible with a modular metal frame infrastructure.
U.S. Pat. No. 6,983,569, which is hereby incorporated by reference herein in its entirety, describes a modular metal wall framing system for construction of walls. However, it is configured for permanent placement of dry wall and thus does not allow for flexibility of placement of wall modules such as decorative panels, bookshelves, cabinets, etc, or for redecoration or remodeling without the aforementioned disadvantages of such projects. Thus, there is a need for an improved modular wall assembly system made of metal components that provides for such flexibility.
The present invention addresses issues commonly found in existing systems by providing a system for modular wall assembly. Developed for the industrialized process of construction, the system of the present invention comprises metal wall framing components including vertical studs and horizontal tracks or cleats. The studs and tracks have female and male engagement means that preferably are slots and tabs for precision alignment between all interlocking components and may be computer numerical control (CNC) cut from a computer-aided design (CAD) file.
Representative modular wall assembly systems according to embodiments of the invention can comprise: a frame, such as metal, comprising: (i) at least one hanging bracket comprising a pair of first male engagement tabs and at least one first wall module engagement cleat; (ii) at least one floor track comprising at least one second male engagement tab and at least one second wall module engagement cleat; and (iii) a pair of vertical studs comprising a series of first female engagement voids configured to receive said first male engagement tabs of the bracket and a series of second female engagement voids configured to receive said second male engagement tabs of the floor track; and at least one wall module comprising at least one horizontal slot configured to receive the first or second wall module engagement cleats such that when installed the wall module is supported on the studs by way of the brackets.
In embodiments, the systems of the invention may include at least one hanging bracket comprising at least one horizontal track (e.g., cleats) and with indexed tabs that interlock with incremental slots in the vertical studs. The horizontal tracks or cleats may be used for hanging wall modules and/or wall systems including shelves and various wall accessories. The wall modules preferably have a horizontal track receiving means or groove, for example which may he a horizontal slot that mates with the horizontal track and secures the module in place at the precise elevation. The incremental slots in the studs may allow for several options for track location to accommodate flexibility for different wall installations. For deeper wall cavities, the horizontal tracks may be so configured that they project deep into a wall to hang deep elements such as bookcases or cabinetry.
For baseboards, the horizontal floor track may include portions or tabs that fold outwardly to engage corresponding slots or grooves in the baseboard panel. The metal wall framing, components may include insulation attached to the face of the framing components such as a thin foam strip to insure a tight seal and provide acoustical protection.

Horizontal tracks 2, vertical studs 3, and floor tracks 4 may be fabricated from a sheet metal material such as stainless steel or aluminum. For these components, three-dimensional models may be rendered in CAD software detailing their specifications, which may be then encoded in instructions to CNC machines for fabricating these components from sheet metal. In preferred embodiments, the tracks, studs, and brackets can each be cut from a single sheet of metal and then cut and folded into the desired configuration. Features for mating the components such as tabs and holes may be positioned for precise alignment between all interlocking components.
First 12 and second 6 male engagement means may be any projection such as tabs, hooks, ridges, or knobs that may fit a corresponding female engagement means such as 7, i.e. an opening dimensioned to mate with the male engagement means. In a preferred embodiment tabs are used. Tabs may take any shape or configuration, such as a single rectangular tab that folds downward at an angle from the base 9 of the horizontal track 2 as indicated by 12 or the pair of tabs that fold sideways from the side walls 16 of the floor track 4 as indicated by 6. On horizontal track 2 first male engagement means 12 may be spaced at both ends of the track 2 and on floor track 4 second male engagement means 6 may be spaced at regular intervals such as depicted in
Female engagement means 7 of vertical studs 3 may take any form to receive corresponding first male engagement means 12 of horizontal tracks 2 and second male engagement means 6 of floor tracks 4 and may be regularly spaced as shown in
More particularly, male engagement means 12 on the top of the track 2 at the ends are configured for mating with female engagement means 7 on vertical studs 3. Wall module engagement portion 11 may project at an upward angle on the other side of the track 2 between male engagement means 12 as shown for mating with slots 8 of corresponding configuration in wall modules 1. Also shown is orthogonal projection 10 on the bottom side of the track 2 projecting on the same side as male engagement means 12.
Further, individual wall panels 1 may be configured to confer specific functions according to particular settings. For example, panels 1 may configured to accommodate peripheral components such as electrical components, data ports, cable TV outlets, communications ports, speakers, and the like, for home or home office settings. In various embodiments, fasteners may be preinstalled on individual wall panels 1 for hanging pictures, mirrors, flat panel TVs/HDTVs or computer monitors, and the like. Alternatively, systems according to the invention may be configured to include shelving for books, knickknacks, and the like as the embodiment shown in
The modular wall assembly system of the invention can be used in any setting where an interior wall is desired, including home, office, retail stores, restaurants, plants, hospitals, and the like. The system of the invention can be installed without the need for specialized contractors or special tools, and panels may be easily replaced by the do-it-yourself home owner who desires easy-to-implement home improvements. As the system allows for easy replacement of wall modules, it provides for frequent interior remodeling without costly, time-consuming, disruptive and messy remodeling projects.
