Abstract:
A simplified and user-friendly reusable modular building block system, for use by the professional architect or home design enthusiast, allowing for the creation of custom architectural scale models of building designs similar in appearance and function to professional scale models produced in architects&#39; offices is presented. The building block system pieces are comprised of interlocking injection-molded solid plastic parts and grouped in five classes of various corresponding shapes and sizes. The construction and grouping of the block system pieces can be connected together at the user&#39;s discretion in a limitless variety of creative configurations, thereby forming the walls, floors, ceilings, roofs, door and window openings, and other building design elements of an architectural model at 1:48 scale (¼″=1′-0″) based on the user&#39;s unique house design, or an existing design if so desired.

PRIOR PROVISIONAL PATENT APPLICATION 
       [0001]    The present application claims the benefit of U.S. Provisional Application No. 60/881,665 filed Jan. 22, 2007, the disclosure of which is hereby incorporated by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention is directed to a method and apparatus for an architectural design aid system, and more particularly, to a method and apparatus for a scale model building block system consisting of different classes of dimensional parts to aid in the development and design of architectural plans. 
       BACKGROUND OF THE INVENTION 
       [0003]    With the recent and ever-increasing interest in architecture and home design among the general public, many non-professional architecture and home design enthusiasts are engaging in activities that provide them with more access to home design-focused information, learning and experiential interaction. For example, the popularity and success of design-focused media properties such as Dwell and Surface magazines, HGTV and TLC television networks, and the plethora of home design software applications and online house plan resellers all attest to the growing desire among design enthusiasts to engage in activities that unlock and empower their inner architect. For many people, designing their dream home is a life-long passion, whether the end result is a purely aspirational pursuit or an actual planned objective. 
         [0004]    For these people, architectural scale models would be extremely useful in the planning and design of buildings, room layouts, decorating schemes, and the like, because they give physical and visual three-dimensional impressions of prospective full-scale structures. They can also facilitate the creative design process by enabling the designer to portray various layouts and design schemes in order to adjust and fine-tune their vision into a final shape and form. 
         [0005]    For these reasons professional architects often create custom architectural scale models in order to effectively present their designs to clients. Architects utilize a variety of materials, including foam board, mat board, balsa wood and basswood, to construct their custom models from scratch and by hand. However, the materials and processes involved in constructing these custom models require a significant level of skill, time, and expense, and are not suitable or realistic methods for enthusiasts to attempt creating models of their own designs, nor would they provide what needs to be a user-friendly and timesaving experience. 
         [0006]    It is clear then that the impressions and visual impact made possible with three-dimensional physical scale models cannot be achieved to the same extent and effectiveness with hand-drafted blueprint and computer-generated renderings. 
         [0007]    Indeed, while pencil and paper facilitate two-dimensional drafting of floor plans and elevations and computer software applications enable three-dimensional renderings on screen, neither provides the enthusiast with the tools to easily create a physical architectural scale model with accurate wall thickness, ceiling heights, roof angles, door and window openings, and other architectural design elements that can be touched, studied and displayed. 
         [0008]    For instance, with regard to a computer software application disclosed in U.S. Pat. No. 5,975,908, issued Nov. 2, 1999 to A. Hulten, a method for constructing a physical scale model of a structure utilizing a computer is presented. However, multiple time consuming steps must be taken before the architect or designer is able to begin construction of the scale model. Indeed, views of the interior and exterior walls of the structure must first be printed out on adhesive-backed paper, the pieces of paper bearing the printed views of the structure must then be affixed to pieces of rigid stock such as cardboard or foam core to create walls, and then cutting or trimming the pieces as necessary must be accomplished. 
         [0009]    The same holds true to a computer software application disclosed in U.S. Pat. Nos. 6,404,424 and 6,556,211, issued Jun. 11, 2002 and Apr. 29, 2003, respectively, both to S. Davis. Herein again a method for constructing a physical scale model of a structure utilizing a computer is presented. Here too multiple time consuming steps must be taken before the architect or designer is able to begin construction of the scale model. In these patents, templates for component parts must first be printed out, trimmed, and then affixed to suitable model-making materials. Only then can the three-dimensional scale model be constructed. 
         [0010]    Thus it is clear that the one form of design-focused activity that currently is not easily accessible to the architecture and home design enthusiast without multiple time consuming intermediary steps is the creation of architectural scale models. No product currently exists in the consumer markets that provides the adult architecture and home design enthusiast with a simplified and efficient modular building block system to create custom architectural scale models of their own dream-house designs similar in appearance to professional scale models produced in architects&#39; offices. 
         [0011]    Alternatively, it should be noted, numerous manufacturers of toy and craft items have developed modular construction systems expressly for children with building elements of various shapes and sizes, including: standard building blocks; “Erector Set” brand of beam and connector elements; “Lincoln Log” brand of interlocking wooden log-shaped components; “Archiblocks” brand building system of stacking wooden blocks produced in a range of architectural styles; and “Lego” brand of variable connectable plastic solids. However, none of these currently existing construction toy and craft items utilize a system that appropriately provides the adult architecture and home design enthusiast with the ability to create free-form structures based on their own house designs that are accurately portrayed at the common architectural scale of ¼″=1′-0″, and similar in appearance and function to professionally-constructed architectural scale models. Thus, none of these items are useful to the enthusiast&#39;s planning and design objectives because they do not accurately give identifiable physical and visual three-dimensional impressions of prospective full-scale structures. 
       SUMMARY OF THE INVENTION 
       [0012]    Accordingly, the present invention is directed to providing a complete set of tools that allows the user to construct custom architectural scale models of their own house designs or existing designs similar in appearance and function to professional scale models produced in architects&#39; offices. 
         [0013]    The primary component of the present invention is a reusable modular building block system that provides a number of interlocking injection-molded solid plastic pieces in various shapes and sizes that are capable of combining together to form three-dimensional architectural models. 
         [0014]    The pieces of the building block system are classified into five distinct classes, each class being based on similarities in shape, size and/or function. The classes of the pieces are: “panels”, “openings”, “inserts”, “connectors” and “details”. The classification system for the part pieces provide the ability for the user to easily create an architectural scale model at 1:48 scale based on a unique or existing house design. 
         [0015]    The part pieces snap together with a precise fit that provides a flush surface between two parts connected together with an interlocking design based on a tongue-and-groove format. The pieces can be disconnected and reconnected at will and therefore reused repeatedly in a limitless variety of connection schemes. 
         [0016]    The present invention, including its features and advantages, will become more apparent from the following detailed description with reference to the accompanying drawings.

         [0017]      FIG. 1  is an illustration of an isometric perspective view of various architectural building component pieces (a-d) as grouped in a first class referred to as “panels”, according to an embodiment of the present invention. 
           [0018]      FIG. 2  is an illustration of an isometric perspective view of an architectural building component piece as grouped in a second class referred to as “openings”, according to an embodiment of the present invention. 
           [0019]      FIG. 3  is an illustration of an isometric perspective view of various architectural building component pieces (a-b) as grouped in a third class referred to as “inserts”, according to an embodiment of the present invention. 
           [0020]      FIG. 4  is an illustration of an isometric perspective view of various architectural building component pieces (a-g) as grouped in a fourth class referred to as “connectors”, according to an embodiment of the present invention. 
           [0021]      FIG. 5  is an illustration of an isometric perspective view of various architectural building component pieces (a-c 2 ) as grouped in a fifth class referred to as “details”, according to an embodiment of the present invention. 
           [0022]      FIGS. 6-22  are illustrations of isometric perspective views showing various architectural building component pieces as they fit together and of elevation (either exterior or interior as the case may be) and plan views of sample applications utilizing the various architectural building component pieces from the five classifications in a scale model, according to an embodiment of the present invention. 
       
    
    
     DETAILED DESCRIPTION  
       [0023]      FIGS. 1 through 5  show the various embodiments of scale model pieces as divided into the differing piece classifications system, while  FIGS. 6 through 22  show how each piece in the classification system fits with others and how they may be utilized in the construction of a scale model. 
         [0024]    To aid in architectural design, the pieces of the architectural design aid system are divided into five classes based on similarities and commonalities with the physical characteristics and intended applications and purposes of the parts. As can be seen, the five classes, and the shapes included in each class, are as follows: “panels”, “openings”, “inserts”, “connectors” and “details”. 
         [0025]    Each class is made up of parts in varying shapes and corresponding sizes and quantities that achieve any one of the stated purposes for the class when applied properly in the construction of the scale model. The varying sizes provided for each unique shape and quantities provided for each part in the building block system have been determined from extensive analysis of both existing and custom house designs, and testing of the invention prototypes. 
         [0026]    Referring now to  FIG. 1 , the first class of pieces in the architectural design aid classification system, that is, the “panels”, are shown. The “panels” consist of rectangular and triangular solid panels with no openings or cutouts and are applied in the scale models as wall, gable, floor, or roof sections. 
         [0027]    Preferably, the “panels” pieces consist of the following:

         [0028]    In the above (and below) chart(s), the actual dimension refers to the actual physical size of the part piece as it can be manufactured, while the scale dimension refers to the real architectural size of the piece the scale model piece is intended to portray. The scale for such measurements is at a 1:48 scale (¼″=1′-0″). Thus, for instance, each of the parts contained in the “panel”, “opening” and “insert” classes charts have a depth (thickness) of 3/16″, thereby representing a 9″ thick building section at. It should also be noted that the dimensions of the finished manufactured scale model pieces may vary slightly from that shown in the charts. 
         [0029]    As can be seen from the above chart, each of the shapes and sizes of the pieces within the “Panels” class (with the exception of part pieces labeled “solid rectangular Low Wall section” and “solid triangular vertical Gable section”) are provided in two connection formats: one version with both male and female connectors (i.e., tongue on one side, grooves on all other connectable sides); one version with only female connectors (i.e., grooves on all connectable sides). It is to be understood, however, that such connectors may be swapped as desired. 
         [0030]    Referring specifically to  FIG. 1(   a ), a solid rectangular Wall/Floor/Roof panel section  10  having four female connectors  14  is shown. Panel section  10  comes in actual dimension widths (i.e., lengths) of 0.375″, 0.5″, 0.75″, 1″, 1.5″, 2″ and 3″, corresponding respectively to scale dimensional widths of 18″, 2′, 3′, 4′, 6′, 8′ and 12′. Each piece is preferably 2.25″ in height and preferably ranges from 0.1875″ to 0.19″ in depth. The female (groove) connectors  14  are constructed in actual dimension to be 0.0625″ in width and 0.125″ in depth. It is to be understood, of course, that the female (groove) connections  14  are to be found at all four edges of section  10 , and that they correspondingly connect to pieces with male (tongue) connectors of other pieces in the system. 
         [0031]    The applications of panel section  10  are as solid rectangular pieces that may be applied for the following purposes: 1) a Wall section—standing upright in either a vertical or horizontal orientation; 2) a Floor section laying flat; or 3) a Roof section laying flat or at angle (for use with the 4-pitch roof ridge and gable-wall sections described below). 
         [0032]    Referring now to  FIGS. 6(   a ) and  6 ( b ), an exterior elevation view and a plan view, respectively, of example applications of panel section  10  are shown. In  FIG. 6(   a ), a scale model  60  has three panel sections  10  being utilized in its construction. In  FIG. 6(   b ), three panel sections  10  are shown interconnected with other system pieces. 
         [0033]    Referring back specifically to  FIG. 1  ( b ), a solid rectangular Wall/Floor/Roof panel section  11  having three female connectors  14  and one male connector  15  is shown. Panel section  11  comes in actual dimension widths (i.e., lengths) of 0.375″, 0.5″, 0.75″, 1″, 1.5″, 2″ and 3″, corresponding respectively to scale dimensional widths of 18″, 2′, 3′, 4′, 6′, 8′ and 12′. Each piece is preferably 2.25″ in height and preferably ranges from 0.1875″ to 0.19″ in depth. 
         [0034]    Preferably, as shown, panel section  11  is constructed having a male (tongue) connector  15  integrally connected along one edge and having female (groove) connections  14  along the three other edges. The male (tongue) connector  15  is constructed to be 0.125″ in width and 0.0625″ in depth. It is to be understood, of course, that panel section  11  may be constructed having the male connector along the shorter edge, or may be constructed having the male connector along more than one edge. For instance, along two, three or even all four edges. 
         [0035]    Like panel section  10 , the applications of panel section  11  are as solid rectangular pieces that may be applied for the following purposes: 1) Wall section—standing upright in either vertical or horizontal orientation; 2) Floor section laying flat; or 3) Roof section laying flat or at angle (also for use with the 4-pitch roof ridge and gable-wall sections described below). 
         [0036]    Referring now to  FIGS. 7(   a ) and  7 ( b ), an exterior elevation view and a plan view, respectively, of example applications of panel section  11  are shown. In  FIG. 7(   a ), a scale model  70  has two panel sections  11  being utilized in its construction. In  FIG. 7(   b ), two panel sections  11  are shown interconnected with other system pieces. 
         [0037]    Referring back specifically to  FIG. 1(   c ), a solid rectangular Low-Wall panel section  12  having four female connectors  14  is shown. Panel section  12  comes in an actual dimensions of 0.75″ in width, 0.75″ in height and 0.19″ in depth, corresponding respectively to scale dimensions of 3′ in width, 3′ in height and 9″ in depth. It is to be appreciated that the depth of panel section  12  may range from 0.1875″ to 0.19″ in depth. It is to be understood, of course, that the female (groove) connections  14  are to be found at all four edges of section  12 , and that they correspondingly connect to pieces with male (tongue) connectors of other pieces in the system. 
         [0038]    The applications of panel section  12  is as a solid rectangular low-wall sections where a full wall is not needed or required. For example, referring now to  FIGS. 8(   a ) and  8 ( b ), an exterior elevation view and a plan view, respectively, of example applications of panel section  12  are shown. In  FIG. 8(   a ), a scale model  80  has one panel section  12  being utilized in its construction. In  FIG. 8(   b ), two panel sections  12  are shown interconnected with other system pieces.

         [0043]    As can be seen from the above chart, each of the shapes and sizes within the “openings” class are provided in one connection format: female-only connectors (i.e., grooves on all connectable sides). It should be noted that all of the shapes and sizes within the “openings” class also provide female connectors on all sides of the opening or cutout itself. Thus, the female (groove) connectors at the four outer edges are available to connect to pieces with male (tongue) connectors, while the female connectors on the inside edges around the cutout opening are available to connect with male connectors on “insert” class pieces. 
         [0044]    As can be seen in  FIG. 2 , a rectangular Wall/Roof panel section  20  with Door/Window/Skylight cutout opening  21  is shown. In a preferred embodiment as shown, the panel section  20  is provided with the cutout opening  21  applied in an upright vertical orientation from the bottom and in a rectangular shape to thereby act as a doorway. It is to be understood, of course, that the doorway can be converted into a window or roof skylight opening when combined with an appropriate “insert” piece (not shown). Further, the cutout opening  21 , with its female connecters  14 , allow for a 1/16″ thick transparent plastic solid rectangular piece to be inserted into the cutout opening to mimic a window pane of glass (when used with an “insert” piece, or provide the potential ability for a modular door or window scale model piece to be inserted into the door or window opening respectively. 
         [0045]    Referring now to  FIGS. 10(   a ) and  10 ( b ), an exterior elevation view and a plan view, respectively, of example applications of panel section  20  are shown. In  FIG. 10(   a ), a scale model  100  has two panel sections  20  being utilized in its construction. One embodiment of panel section  20  is shown acting as a doorway, while the other embodiment of panel section  20  is shown acting as a window (with appropriate “insert” piece).

         [0048]    As can be seen from the above chart, each of the shapes and sizes within the “inserts” class are provided in one connection format: male-and-female connectors (i.e., tongue on two sides, groove on two sides). The male connectors are located on each ends of the “inserts” pieces, while the female connectors are located on the sides (top and bottom) of the “inserts” pieces. It is to be understood, of course, that such positioning of the connectors, either individually or as a pair, may be switched between such sides and ends. 
         [0049]    Referring specifically to  FIG. 3(   a ), a ¾″ wide solid rectangular knee-wall/header insert section  31  with two male and two female connectors (not labeled) is shown. As can be seen, insert section  31  can be inserted into a doorway opening  30  as a knee-wall to convert the doorway into a window opening. It is to be understood, of course, that such insert section can also be connected as knee-wall or header with other solid wall sections to form custom window and doorway openings as desired. 
         [0050]    Referring now to  FIGS. 11(   a ) and  11 ( b ), an exterior elevation view and a plan view, respectively, of example applications of insert section  31  are shown. In  FIG. 11(   a ), a scale model  110  has three insert sections  31  being utilized in its construction. The middle of the three insert sections has been inserted as a knee-wall in doorway opening  30 , while the outer two of the three insert sections have been placed as knee-walls on either side of the doorway opening. In  FIG. 11(   b ), the three insert sections are shown interconnected with the other system pieces. 
         [0051]    Referring back specifically to  FIG. 3(   b ), a ½″ high solid rectangular knee-wall/header insert section  32  with two male and two female connectors (not labeled) is shown. As can be seen, insert section  32  can be connected as a header between two solid wall sections  33  and  34  with female connectors to form a custom window and/or door opening. Such versatility allows for creating custom wall openings as desired. 
         [0052]    Referring now to  FIGS. 12(   a ) and  12 ( b ), an exterior elevation view and a plan view, respectively, of example applications of insert section  32  are shown.

         [0055]    With regard to actual physical construction, all parts in the building block system connect together with a male (tongue) and female (groove) connection between any two adjacent parts. The male connector on one part interlocks with the female connector on the adjacent part. The male connector is preferably ⅛″ wide, 1/16″ thick, and runs the length of the side of the part it is molded on, stopping ⅛″ from both ends. The female connector is preferably ⅛″ deep, 1/16″ wide, and runs the length of each connectable side of the part where there is no male connector. The “face area” dimensions of the parts refer to the flat surface area that is visible from the viewer&#39;s lines of site when the part is connected in place in its intended location, with all adjacent parts in place as well. This means that the face area dimensions do not include the male (tongue) connector that is not visible when inserted into the adjacent female (groove) connector.

In  FIG. 22(   c ), the staircase  53  is shown interconnected with the other system pieces. 
         [0078]    Thus, as can be seen from the above description of the present invention with reference to the accompanying drawings, each of the pieces in the building block architectural design aid system are designed in a manner that allows each to be used for more than one purpose, with the resulting purpose depending on how the user chooses to apply and orientate the part. For example, a 0.5″ wide×2.25″ high×0.1875″ thick “full-height solid wall” section (1:48 Architectural scale=2′×9′×9″) turned 90 degrees is transformed into a 2.25″ wide×0.5″ high×0.1875″ thick (1:48 Architectural scale=9′×2′×9″) “knee-wall” or “header” section. The same part oriented horizontally (laying flat) is transformed into a “floor/ceiling” or “roof” section. This intended versatility of each part provides the user with the ability to construct a model with relatively little limitation on custom design capabilities with a relatively small variety of part shapes. 
         [0079]    Accordingly, the design of the parts and the total sum of the parts provide the ability for the user to create an architectural scale model at 1:48 scale based on a unique or existing house design and can easily accommodate 5,000 square feet of floor space, with one or more levels, 9-foot or higher ceiling heights, and with a sloped 4-pitch roof or a flat roof. Depending on the level of skill and imagination of the user, the models created with the invention can conceptually portray visual outline impressions of most existing architectural styles to a similar extent that a professional architect&#39;s model typically portrays such an impression. 
         [0080]    The invention&#39;s building block system is designed to contain enough parts with versatile applications for each to build a scale model based on a house design with up to 5,000 square feet of floor space with one or more levels. Because the system provides easy changeability during the model construction process, and is also reusable, the invention allows the user to adjust and refine the design of their dream-house as they shape the physical three-dimensional scale model of their vision. 
         [0081]    In addition to the classifications and construction of the differing pieces of the scale model building block system, the present invention may be featured with supportive components to both instruct and facilitate the user&#39;s interaction with the block system. For instance, a Work Pad, Architectural Scale Ruler, and Tutorial/Instructional Manual may be utilized to aid in the architectural design process. 
         [0082]    The first additional feature, the Work Pad is designed as a 16″×20″ plastic pad printed with a 4 squares-per-inch grid. This component provides a 1:48 scale grid to visually facilitate placing the upright wall sections with the desired layouts and room dimensions before connecting them. 
         [0083]    The second additional feature, the Architectural Scale Ruler is designed as a 12″ plastic ruler with two relevant scales to provide a quick method for the user to measure the parts and spaces: 1) Architectural—¼″=1′-0″; and 2) Standard—1″=1″. 
         [0084]    The third additional feature, the Tutorial/Instructional Manual is a printed and spiral-bound manual with instructions and tutorials. Such instructions and tutorials educate the user as to the system pieces and provide guidance in the architectural process.
