DETAILED DESCRIPTION

(16) Referring first to FIG. 1, a small modular building 20 is shown installed in a parking lot 10 in order to teach how to make and use the claimed invention. Parking lot 10 in the illustrated example is associated with an existing building or collection of buildings S such as a superstore, shopping center, or retail mall (hereafter “store”). Parking lot 10 need not be associated with a functioning, existing store, however; the parking lot could be an abandoned or empty lot, or a lot associated with a closed or abandoned store.

(17) Modular building 20 is configured for retail sale of goods and/or services, ideally complementary to the business of any existing store S, for example a drive-thru for coffee, donuts, etc. Modular building 20 may also include walk-in or sit-down service for a small number of customers, with limited seating and an ADA-approved restroom. Another possible example of a complementary small business suitable to be conducted from modular building 20 is a pharmacy or other typical in-store department of existing main store S, such that modular building 20 functions as a physically separate department of the main store, with corresponding signage, that can be accessed directly from the parking lot.

(18) Modular building 20 includes a one-story or ground-level main rectangular service module 30, a two-story tower 40 connected to main service module 30 to form a contiguous single building with a common interior, and a drive-thru carport 70.

(19) Main service module 30 houses the equipment and work staff needed to provide the goods or services (e.g., coffee) for drive-thru customers, and optionally includes seating for customers if sit-down service is offered. Equipment will depend on the type of business, but things such as stoves and ovens, refrigerators and freezers, counters, sinks, dishwashers, computers, cash registers/terminals, coffee-brewing machines, drive-thru order taking systems, lighting, and display boards and cabinets would be typical for a food-related business.

(20) Tower 40 includes upper and lower modular cube sections 50, 60 each of which comprise a room. Upper section 60 is the “mechanical” room, housing the primary in-house electrical and plumbing apparatus such as HVAC equipment, junction boxes and breaker panels, and water tanks and treatment. Lower section 50 is a restroom, meeting ADA standards, with a door 33′ connecting it with the interior of main service module 30 for the use of workers and customers. Lower section 50 may also include a janitorial storage area for cleaning supplies.

(21) Utilities 18 such as water, electrical power, gas, sewer, and/or communications are provided to the modular building 20 via one or more directional bores schematically shown at 16 in FIG. 1. Directional bore 16 preferably opens in an unpaved area outside the parking lot 10 in known manner, and is drilled laterally underneath the parking lot surface to a location under the modular building's installation site using known techniques. The in-house utility systems in the modular building may be connected to the water, power, gas, and communication-using apparatus in building 20 with known types of connections located in the base of the lower tower module 50 and extending or branching to the upper tower module 60, the connections schematically shown at 19 in FIG. 1.

(22) Modular building 20 includes a rigid drive-thru carport 70 comprising a sidewall 72 and a roof 71 connected to the main service module 30, for example at the roof 31. Drive-thru service features such as cashier and food delivery windows 32 are provided in the main service module 30, at least one of which (FIGS. 4, 5, and 9) is associated with the area covered by carport 70. A door 33 (FIGS. 4, 5, and 11) is provided in at least one of the walls of service module 30 for entry and exit by workers and customers.

(23) FIG. 2 shows the constituent modules 30, 50, and 60 that form the modular building 20, loaded onto two tractor-trailers 80, 82 of known type for delivery to the parking lot. Main service module 30 is sized to fit on and make substantially full use of one tractor-trailer bed 81 for delivery to the parking lot installation site in a single story configuration. Tower cube modules 50 and 60 and carport 70 are sized to fit on and substantially fill another substantially identical tractor-trailer bed 81 for delivery to the parking lot installation site in a single story disassembled configuration. In the illustrated example, main service module is approximately 9′ (feet) wide by 27′ (feet) long, making full use of a 9′×27′ standard tractor-trailer bed. Illustrated tower cube modules 50 and 60 are dimensionally similar with 9′×9′ footprints and similar (although not necessarily identical) wall heights. Carport 70 may have a sidewall height approximating the height and/or width dimensions of the tower cube and main service modules as illustrated in FIG. 2, for example 9′ (feet), in order to fit neatly into the remaining space on the second tractor-trailer bed 81 with the tower cube modules. The length of the carport roof portion may be longer, and the carport can be positioned so that at least some of the roof overlaps an adjacent module on the trailer.

(24) Likewise, if a third tower cube (not shown, but substantially the same as either one of modules 50, 60) is desired for a taller assembled tower, or if modules 50 and 60 are sized differently to take up the entirety of the trailer bed on their own, the example illustrated carport sidewall and roof dimensions can be sized to fit or nest against one of the sidewalls and over an upper edge or roof portion of the adjacent tower cube module for delivery on the same trailer.

(25) FIG. 3 shows the constituent modules of building 20 in an exploded assembly relationship relative to the designated installation site 12 on parking lot 10. Installation site 12 is provided with anchor points 90 prior to delivery and assembly of the modules. In the illustrated example, anchor points 90 are commercially available concrete tube forms placed in bores 91 drilled into the pre-existing parking lot surface and subsurface, in a pattern corresponding to the lower frame outlines of the first-story building modules in their joined-together configuration. Modules 30, 50, 60, and 70 are pre-built and can simply be lowered or skidded into position to be joined together over the bores 91 and their empty concrete tube forms 90, with anchors or ties extending from the lower module frames into the tubes to be secured with a subsequent filling of concrete or equivalent anchoring material poured into the tubes.

(26) FIGS. 4 and 5 are schematic representations of example interiors of the main service module 30 and the lower tower cube module 50. The relevant interior features and equipment 32, 52 that make the joined modules functional as a retail business are pre-installed in their respective modules prior to delivery to installation site 12. The same is true of the mechanical and utility-room features of the upper tower cube module 60. The modules 30, 50, and 60 are accordingly pre-built prior to delivery to the installation site on a parking lot, so that connecting them to one another and to the on-site utility supply lines (water, sewer, electric, communication) makes the modular building 20 functional. It should be understood that minor finishing and customizing touches may be reserved, if desired, for installation or application after the basic pre-built functional modules are delivered and assembled on-site, such as painting, trim, floor finishes, etc.

(27) FIGS. 6 and 7 show the preferred frame-and-panel construction of the modules 30, 50 and 60. In FIG. 6, the lower edges 34, 54, 74 of the respective ground-level modules (main, restroom, and carport) are formed by rectangular steel tubing to form a steel skid foundation. The concrete tube forms 90 are installed to be aligned with the outermost lower frame members 34a, 54a, 74a in a desired anchor pattern. Cross-members 34b, 54b serve as internal frame bracing and/or floor panel supports. The steel frame members may be joined using known types of mechanical fasteners or welding techniques. FIG. 6 also shows forklift channels 34c and 54c associated with the lower frame members of each module, useful for moving the modules on and off delivery trucks and for positioning or lifting the modules at the building site. The steel frame members may be supplemented in known manner, for example with treated lumber overlaid on the frame to help bear the weight of wall panels.

(28) FIG. 7 additionally shows structural insulated panels of known type used for the walls and roof portions of the various modules, joined directly together in known fashion. Main service module 30 has roof panels 35, wall panels 37, and floor panels 39. Lower tower cube module 50 has ceiling, wall, and floor panels 55, 57, and 59. Upper tower cube module has roof and wall panels 65, 67, with the ceiling panel 55 of the lower tower cube module functioning as the floor of the upper room. While the example frame and panel construction is preferred for the modules, other known types of construction and/or materials may be suitable and used depending on factors such as preference, climate, and local building codes. The exterior surfaces of the modules may be faced with various materials suitable for the local aesthetic preferences or requirements, weather conditions, or other factors.

(29) The lower steel frame/foundation members 34a, 54a, 74a of the modular building 20 are secured in the pre-installed concrete tube forms 90 via angle iron members 92 connected at one end to the steel frame/foundation members and at their other end to hook anchors 94. The lower ends of hook anchors 94 extend down into the interiors of concrete tube forms 90, where they are connected to reinforced steel anchor structures 95 located in the concrete tube forms. In the illustrated example, anchor structures 95 are formed from a vertical rectangular array of spaced rebar 96 connected with a spaced array of horizontal steel hoops 98 to form a lattice-like column. Once the anchors 94 and anchor structures 95 are positioned in concrete tube forms 90, concrete 93 can be poured into the tube forms, flowing around the anchors to harden and secure the modular building in place.

(30) It will be understood that other known anchoring structures and techniques suitable may be suitable for securing modular building 20 to an existing parking lot, but the structure and method disclosed above is preferred and believed to be superior to other tie-down type foundations. The manner of assembling or connecting the pre-finished modules 30, 40, 50, and 70 to one another will be apparent to those skilled in the art, and may comprise any known technique or combination of techniques, such as but not limited to the use of self-tapping metal screws, coarse-threaded bolts through pre-formed bores in frame members, nailing, structural adhesives, and combinations thereof.

(31) FIGS. 1-7 also generally show the upper walls 67 of tower portion 40, i.e. the sidewalls of the upper tower cube module 60, being used as the “billboard” or sign for the retail business operated out of modular building 20. The height of the walls of the upper cube module 60 provide suitable square footage and a height above the roof portion of main service module 30 to allow the name of the business to be clearly displayed on a designated signage portion 69, optionally on all sides to potential customers in the parking lot. This sign-supporting capability of the upper walls of the tower portion of the modular building eliminates the need for costly (and sometimes restricted) pylon signage, because the sign surfaces are part of the building itself.

(32) FIGS. 8-14 illustrate the external appearance of the example assembled building of FIGS. 1-7 from different perspectives. The proportions and relative dimensions of the illustrated modules, their roof configurations, door and window configurations, the location and shape of the carport, and the relative positions of the modules to one another when assembled into a building may vary from those shown according to aesthetic preference, available delivery trailer dimensions for the various modules, number of modules assembled, and other factors that will now be apparent to those skilled in the art. Exterior surface finishes may of course vary depending on aesthetic preference and the illustrated modules are not limited to any particular surface finish or material.

(33) The modular nature of the main service module 30 and the tower cube modules 40, 50, their simple manner of assembly to one another and placement and anchoring on a parking lot building site, and the centralized utility function of the upper tower module allow different combinations of modules to be assembled as needed or desired with differing relative positioning to one another. For example, as shown in FIG. 15, an extra ground-level service module 30′ can be added between the main service module 30 and the tower modules 40, 50 so that the outer service module 30 can be dedicated for customer seating, while the inner service module 30′ functions as the main kitchen and service area, with pass-through interior doors between the main service modules 30, 30′ and the lower bathroom module 40 on the assembled tower. Another example would be positioning the tower assembly 40, 50 along a middle portion of the sidewall of main service module 30 rather than at one end of the main service module sidewall.

(34) It will finally be understood that the disclosed embodiments represent presently preferred examples of how to make and use the invention, but are intended to enable rather than limit the invention. Variations and modifications of the illustrated examples in the foregoing written specification and drawings may be possible without departing from the scope of the invention. It should further be understood that to the extent the term “invention” is used in the written specification, it is not to be construed as a limiting term as to number of claimed or disclosed inventions or discoveries or the scope of any such invention or discovery, but as a term which has long been used to describe new and useful improvements in science and the useful arts. The scope of the invention supported by the above disclosure should accordingly be construed within the scope of what it teaches and suggests to those skilled in the art, and within the scope of any claims that the above disclosure supports in this application or in any other application claiming priority to this application.
