This disclosure relates to construction panels and, more specifically, in a preferred exemplary embodiment, to a modular panel that is built up as a lattice of hardwood strips on a thin veneer backing sheet, and composite material such as particle board is used as filler material, with female joiner locks that permit attachment of facing material embedded in the particle board portions.
Construction panels such as those used for many modular furniture kits are typically made of particle board material. Such particle board construction is subject to tearing out of fasteners at mating joints, thereby destroying the integrity of the piece of furniture.
The only conventional technique of overcoming this deficiency of using particle board panels for furniture is that of building the furniture out of more substantive materials such as hardwood or plywood, but such approaches add substantial cost to a furniture design.
The present disclosure describes a novel approach for improving construction projects using panels based on particle board composite material by providing a hybrid construction in which a lattice formed of pre-cut wood strips provides strength and modularity and composite material is used as a filler to provide compressive strength and to support female locking pieces that permit facing materials to be added for appearance.
This hybrid approach eliminates the conventional problem of fasteners tearing out of particle board joints since the lattice strips of the lattice structure serve as material to make joints, thereby providing much stronger joints equivalent to those of much more expensive furniture using solid hardwood. That is, when the modular construction board of the present invention is used in lieu of typical construction materials such as plywood, particle board, drywall, MDX, or even cement, the lattice structure provides a strong grid of points with which to connect to other boards or walls without having to use the particulate material, which is a cheaper and less reliable fastening material. The lattice-based panel of the present invention thus effectively provides a panel having the advantage of strength of the lattice material pieces without having to purchase or use an entire panel of this more expensive material.
When used in furniture construction, including, for example, built-in kitchen or bath cabinets, in some exemplary embodiments, this hybrid approach provides panels having exposed portions of the composite material that can have embedded therein female locking pieces, similar to push-in rivets, to permit facing materials to be added for external appearance as a removable facade, as well as functional and decorative knobs and/or handles. When used in a wholesale furniture production environment, these construction panels permit fabrication of particle wood-based furniture that has higher quality and survival rate with minimal cost increase.
The novel construction panels described herein additionally can provide panels that can be used for construction applications other than modular furniture construction, including, for example, floor panels or wall or ceiling panels.
In a preferred exemplary embodiment, the construction panels of the present invention additionally provide composite material that are slightly recessed relative to the external surface of the lattice strips, so that adhesive or mortar material can be easily spread on the exterior surface with no leveling difficulties, in preparation for application of tiles or other covering materials.
The accompanying drawings illustrate several embodiments and, together with the description, serve to explain the principles of the invention according to the embodiments. It will be appreciated by one skilled in the art that the particular arrangements illustrated in the drawings are merely exemplary and are not to be considered as limiting of the scope of the invention or the claims herein in any way.
The present invention discloses a hybrid construction panel using strips of wood that are interlocked to form a lattice structure on top of a veneer panel, with composite material such as particle board used as a filler for the lattice structure. The lattice structure strips can be used to make strong, solid furniture joints where panel sections meet, for example, at corners and edges of cabinets, or for strong attach points for connecting a construction panel to other structural components such as floor or ceiling joists or wall studs. The composite filler material adds overall strength and stability to the panel and can serve as attachment points for facing material or for a surface upon which to apply adhesive or grout for tiles or other facing material.
The invention is described by reference to various elements herein. It should be noted, however, that although the various elements of the inventive apparatus are described separately below, the elements need not necessarily be separate. The various embodiments may be interconnected and may be cut out of a singular block or mold. The variety of different ways of forming an inventive apparatus, in accordance with the disclosure herein, may be varied without departing from the scope of the invention.
Generally, one or more different embodiments may be described in the present application. Further, for one or more of the embodiments described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the embodiments contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous embodiments, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the embodiments, and it should be appreciated that other arrangements may be utilized and that structural changes may be made without departing from the scope of the embodiments. Particular features of one or more of the embodiments described herein may be described with reference to one or more particular embodiments or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular embodiments or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the embodiments nor a listing of features of one or more of the embodiments that must be present in all arrangements.
Headings of sections provided in this patent application and the title of this patent application are for convenience only and are not to be taken as limiting the disclosure in any way.
Devices and parts that are connected to each other need not be in continuous connection with each other, unless expressly specified otherwise. In addition, devices and parts that are connected with each other may be connected directly or indirectly through one or more connection means or intermediaries.
A description of an aspect with several components in connection with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible embodiments and in order to more fully illustrate one or more embodiments. Similarly, although process steps, method steps, or the like may be described in a sequential order, such processes and methods may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the embodiments, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, or method is carried out or executed. Some steps may be omitted in some embodiments or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.
When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.
The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other embodiments need not include the device itself.
Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular embodiments may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Alternate implementations are included within the scope of various embodiments in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.
The modular construction panels of the present invention are particularly useful for construction projects in a home, office, or shop since they can be used to construct furniture, cabinets, and shelves, but also could be used for coverings for floors, walls, and ceilings.
In the exemplary embodiments described herein, the composite material is particle board, because one exemplary intended application is furniture and cabinet making, where particle board is already commonly used. Particle board, also known as chipboard, is an engineered product manufactured from wood chips or jute-stick chips and a synthetic resin or other suitable binder, which is pressed and extruded. Often waste-wood such as wood chips, sawmill shavings, or even sawdust are mixed together with resin and treated by a heat pressing process.
Another composite material that could be used in the present invention would be the wood fiber product described as fiberboard, as demonstrated in categories based on density. Standard fiberboard products include low density fiberboard (LDF), medium density fiberboard (MDF) and high density fiberboard (HDF).
In other applications such as floor, wall, or ceiling panels, another possible composite material could be oriented strand board (OSB). OSB is also sometimes used in furniture making. OSB is typically manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and synthetic resin adhesives. Using OSB as composite might provide a strength/weight benefit compared to using particle board composite.
Yet other applications might use non-wood composite materials, such as ceramic fiber boards made from a wet forming process using alumina-silica fibers and binders. Even paper fibers have been used to form paperboard, which is another composite material that could potentially be used to form panels based on the concepts of the present invention.
Depending on specific fabrication details, the upper surface of the underlying veneer sheet 110 could be coated with an adhesive to hold the longitudinal lattice strips 112, or the bottom surface of the longitudinal lattice strips 112 could be coated with an adhesive to adhere to the sheet 110. As shown in the side view in
In the next step 106, the transverse lattice strips 114 are placed on the longitudinal strips 112, and, in some exemplary embodiments, female locking nuts (see
Specific details are not discussed herein of whether adhesives are used for adhering the lattice strips 112, 114 to the backing veneer sheet 110 and the dado cuts 112B of the longitudinal lattice strips 112 to the dado cuts 114B of the transverse lattice strips 114 and, if so, what specific adhesives are used, or whether the resin used to form the composite filler material 120 as this material is added can also serve as an adhesive for the lattice strips 112, 114. These are details that would be straightforward to one of ordinary skill in the art of fabricating composite panels using, for example, particle board composite material. Additionally, the specific details of the exact sequence of how the transverse lattice strips 114 are fitted to the longitudinal strips 112 relative to the addition of the composite material mixture are details considered beyond the scope necessary for understanding the concepts of the present invention and would depend upon different fabrication details of different composite materials, as these various possible composite materials were mentioned above.
Although the lattice strips 112, 114 are depicted as having a rectangular cross-sectional shape, as shown in
In an exemplary embodiment of modular panels used for construction of furniture and cabinets, as exemplarily shown in
In other applications, such as construction panels used for flooring, ceiling, or wall panels, a different lattice material such as pine or fir strips and a different composite filler material such as OSB might be preferable, for cost and weight considerations. When the modular panels are intended for use as construction components such as floor or ceiling panels rather than cabinetry panels, the dimensions would preferably match their intended use. For example, floor and roof joists and wall studs are conventionally based on either 16- or 24-inch intervals, so the lattice strips used in modular panels intended for 16-inch construction might be based on such intervals as 4- or 8-inches rather than the 6-inch intervals described for the exemplary embodiment in
Additionally, it is noted that the panel in
Second, in the exemplary embodiment of
The purpose of the female joiner inserts 202 is to permit facing material 210 to optionally be affixed to the front surface of modular panel 200. For example, if modular panel 200 is used as the front panel in a cabinet carcass of a kitchen cabinet, these female locking joiner inserts 202 would permit sections of facing material 210 to be affixed to the front surface of the cabinet as shown in
In the exemplary embodiment shown in
Although a preferred exemplary embodiment places a female joiner insert 202 at the center points of all the composite material portions, it should be clear that in other embodiments the female joiner insert 202 could be located in other locations than the center point of a composite material portion or that the female joiner insert 202 could be placed in fewer than all portions of composite material or even that no female joiner inserts are placed in any composite material portion.
Third, the gap 122 above the composite material 120 is an intentional gap that could serve as a reservoir for adhesive, grout, or other mortar material should the modular panel 200 be used for backing for tiles or a veneer layer that might be used as an exterior appearance finish surface for the modular panel 200.
If it is desired to apply tiles on the top of the cabinet, by orienting the top section 304A with the composite material side exposed and facing up, the small gap above the composite material could serve to easily apply and level the tile adhesive. By orienting the side sections 304B, 304C to have their veneer backing face outward, this veneer could serve as a final exterior appearance surface for the side panels of the cabinet, and the lattice strips now exposed on the interior side of the side panels 304B, 304C could be drilled with small holes to hang inserts or pegs to support shelves or drawer guides if drawer are to be added inside the cabinet instead of shelves. Similarly, the rear panel 302B could be oriented to use its veneer backing layer as the finished exterior material for the back of the cabinet and use the lattice strips on the interior surface to help support and stabilize shelves if shelves are to be installed.
In contrast to the side and rear panels, the front panel 302A would have its lattice strips facing outward, in order to permit these lattice strips to be trimmed to accommodate two hinged doors for opening up to access an interior having shelves. Alternatively, if drawers are to be added to the interior rather than shelves, then the lattice strips would be trimmed to accommodate openings for slide-in drawers. In either case, whether hinged doors or drawers are chosen, having the lattice strips facing outward on the front panel 302A permits the locking nut inserts in center points of the composite material sections to be used for affixing facing materials for either two hinged doors or for two or more drawer frontispieces, with the door hinge and handle hardware and the drawer knobs being then attached to the front surface of the facing material.
Thus, in view of the simple example shown in
The dual sided female locking joiner 400 includes openings 404 on each side and a wedge-shaped central portion 406. The wedge-shaped central portion 406 keeps the female locking joiner 400 in place and prevents it from ripping out of the panel. As shown in
This modular type board can be used in lieu of typical construction materials such as plywood, particle board, drywall, MDX, OSB, or sometimes even cement. The lattice structure components of the panels provide a strong grid of attachment points for forming strong joints with other panel sections and to connect to other boards or walls without having to use particulate composite material, which is cheaper and less reliable. The clasping system using the female locking joiner nuts embedded in the composite material creates the ability to further connect any material or prefabricated face such as floor, wall, or ceiling tile, raised wood faces, or any manner of material, with precision and ease and without having to deal with leveling mortar or installing a separate underlayment. Additionally, it is possible to use any material for the veneer backing, as well as permitting more utilitarian use of the back side of the panel by finishing this surface in any desired manner.
The modular panels of the present invention would allow any large scale, mid-level, or small construction project to be completed using a product that has all the advantage of using a whole solid piece of lattice material without having to purchase that much of the product. In cabinetry all of the joints in American or European style cabinets can be connected on a “stud” per se, as meaning one of the hardwood lattice strips, thereby providing a frame for furniture that eliminates the problem of tearing out at connection points in big box furniture conventionally made of particle board composite material. Additionally, a facing material can be connected simply and the connection mechanism even permits such facing material to be optionally disconnected in the future to update for styling. For tiling, the panels create a level surface on which tiles can be connected with room for grout or even flush, and the panels circumvent the need for mortar and leveling.
The modular panels can be fabricated in modular form to allow the user to cut out individual parts to make custom drawers or doors and would allow the user to route the edges of the cut out pieces or the remainder of the board for cabinetry with inset doors and drawers. The female locking inserts also allow for easy installation of knobs or handles for any use.
The modular panels could also be used for high end soundproofing or even modular insulation, and could potentially be used even for roof tiling or solar roof tiling.
