Conceptually, such modular structures are intended to be mass produced, attractive, structurally sound dwelling or office units capable of providing the customary comforts with little or no maintenance being required of the occupants. A numberof building mate rials notably, molded fiberglass, are available for manufacturing such modular structures within the intended design concepts.

In practice modular structures are fabricated at factory locations and are shipped for assembly and installation at the building site. Preferably, the modular structures are fabricated in sections for convenient shipment and assembly at on-sitelocations. In this SUMMARY OFTI-IE INVENTION The present invention is directed to modular structures and more particularly to a-basic construction section from which a variety of modular structures may be assembled. The basic construction section is readily fabricated from a suitable construction material such as fiberglass and is convenient for shipment to and assembly at a remote construction site. The basic construction section of the present invention forms a portion of the side wall, roof, and base portion of the completed modular structure. Preferably, the basic construction section is of sufficient strength to have load-bearingcapability in the finished modular unit. The load-bearing ability inheres in the design of the basic construction sections which include integral generally perpendicular side wall panels joined at their top edges to a roof panel and at their bottom edges to a base panel. The basic construction sections are further provided with connector flanges at the exposed edges of the side, top, and base panels for connection to adjacent sections in assembly of a modular unit. Eachbasic construction section, when assembled, contributes to a rigid box-like modular structure without requiring an internal support frame. The connector flanges are turned outwardly (with respect to the interior of the modular unit) and contribute to the strength and rigidity of the side walls, roof, and base portion of the assembled modular unit. The basic construction sections include, as desired, suitable openings for doorways and windows.

Basic construction sections may be arranged to form a single modular structure or a variety of multi-modular structures as desired to accommodate individual taste and space requirements. For example, the basic construction sections may be assembled to form a single modular unit, one story high, having a generally rectangular or square floor plan. The basic construction sections when assembled form the side walls, a portion of the roof, and a portion of the base of the modular unit.

. square floor plan.

In another modular unit according torthe, present invention, the basic construction sections may be arranged to provide one storyormulti-story units having larger floor plans than the basic rectangular or square floor plans. Such larger floor plans are defined by, arranging adjoining modules in various patterns.

The basic construction sections of the present inventionmay be formedfrom suitable materials such as molded fiberglass at a central factory location. The basic sections are designed for convenient and economical shipment to the point of assembly. Modular units may be assembled quickly and easily at the construction site.

DETAHJED DESCRIPTION OF THE INVENTION Referring nowto FIGS. 1-4 of the drawing, a basic modular dwelling unit locomprises a plurality of, preferably four, corner sections or basic constructionsections 12, joined by suitable flanges 14, to define upstanding side walls 16 and portions of the roof 18 and base 20. Each corner section includes a pair of

vertical panels

22 and 24 joined at a corner line" 26 in approximate right angle relation to each other. Each

vertical panel

22 and 24 forms part of the upstanding side walls 16 of the modular unit. If desired, one of the vertical panels in each corner sectionmay be provided with an open area to accommodate a window 28 or door panels 30. Each corner section 12 includes top and

bottom wedge panels

32 and 34 which join the adjacent vertical panels at their top and bottomedges respectively to define the portions 18 and .20 of the roof and base of the modular unit.

Each of the

vertical panels

22 and 24 and the top and I

bottom wedge panels

32 and 34 carry

flange members

36, 38, 40, 42 respectively. Each flange member is connected in approximate right angle relationship to its respective carrier panel. The

vertical flange members

36, 38 are joined to corresponding flange members of adjacent corner sections in assembling the completed modular unit. The top flanges 40 secure roof panels 44 to the corner section by means of suitable fastener means (not shown). The bottom flanges 42 secure the entire modular unit to a modular unit supporting foundation 46 which preferably is formed of concrete. The foundation may serve also as a suitable location for various dwelling utilities, such as heating and plumbing (not shown).

As best illustrated in FIG. 3, a basic modular unit is formed by joining four corner sections 12 at their adjacent

vertical flange portions

36, 38. The basic modular unit may have a generally square floor plan as illustrated or may be rectangular in form if desired. A floor member 48 supported by the corner sections is located within the modular unit to span the open area over the foundation. The corner sections when assembled define a basic modular unit having an open roof area (indicated by broken line 50 in FIG. 3) which is covered by the roof panels 44. If desired, the roof panels may be transparent or translucent to aid interior lighting of the dwelling unit.

In one form of the invention a deep roof panel 44a may be used to create additional space within the mod ular unit. As best illustrated in FIG. 4, a sleeping loft 52 is mounted on adjacent top flange members 40 to accommodate one or two persons. Access to the sleeping loft is by a suitable wall mounted ladder 54, shown in FIG. 3.

The modular unit may be furnished with basic facilities such as lavatory 56, a storage area 58, kitchen and dining area 60, and living area 62, as illustrated in FIG. 3.

A basic modular unit according to the present invention comprises six performed sections, i.e., four corner sections 12 and a pair of roof panels 44 together with a floor member 48 which are truckedto a building site and assembled upon the concrete foundation 46. A comer section measuring 9 feet and feet along adjoining side wall panels will provide a 14 foot X 14 foot dwelling providing basic housekeeping facilities and storage for four persons. The living area may convert to sleep two persons and two additional persons may be accommodated in the optional sleeping loft 52.

The basic modular unit may be expanded by stacking units as shown in FIGS. 5 and 6. Each of the stacked units is formed from a plurality of comer sections as described above in connection with FIGS. 1-4. The lower modular unit is fastened to a concrete foundation by means of bottom flanges. A floor member spans the open foundation to provide a floor in the lower unit.

The top unit 100 is stacked on the lower unit 1012 with its downwardly directed base flanges 42 engaging and fastened to the upwardly directed top flange members 40 of the lower unit. The

flanges

40, 42 extend to the outer edges in a rectangular or square patterns (as seen in FIGS. 3 and 5) to provide adequate support and stability of the upper unit. In addition the vertical external 14 flanges may be reinforced by suitable strength members 64 to add rigidity and stability to the stacked units.

The upper unit is provided with a floor 66 reinforced by suitable beams 68. The floor is open 70 to define a stair well for access to the upper compartment 72 by means of a suitable ladder 74. A roof member 44 caps and encloses 30 the upper unit as described previously.

Window 28 and door panels are included in the wall panels of the multi-modular unit.

A bilevel or stacked module includes the floor plan features of the basic modular unit as described above, and, in addition the upper level provides individual bedrooms or a sleeping dormitory. Ordinarily, the stacked modules do not require the optional raised roof panel, however, such raised roof panels may be used as desired.

In another form of the present invention, (shown in FIGS. 7 and 8), two modules 10c and 10d can be assembled adjoining each other providing a more varied floor plan for greater storage and for private bedrooms. A corner section may be eliminated from each of the two modules and 10d which may be joined at corresponding flanges. That is, each module includes three instead of four corner sections. Preferably, one of the outwardly extending flanges 36 is eliminated (compare corner sections FIG. 2) for ease in joining adjacent modules. The open roof defined by the corner sections may be closed by the usual roof panels 44. Of course, one or more deep roof panels may be used to provide sleeping lofts or added storage space as described above. In this form a corresponding foundation is provided for the extended double module.

A floor plan of any desired configuration may be arranged, and typically, the floor plan may include

separate bedrooms

76, 78, a lavatory 80, a kitchen area 82, a dining area 84, a living area 86 and storage space 88. Windows 28 and doors 30 may be provided as described in the module side walls.

An extended double module can comfortably accommodate six persons.

The modular units according to the present invention are preferably constructed from molded fiberglass. The comer sections are structurally self-supporting and eliminate the need for an interior frame within the unit. The modules may be of single wall thickness or of an insulated sandwich construction according to geographic location and intended use.

In constructing a modular unit according to the present invention, a concrete foundation is poured on site. Then two corner sections are positioned on the foundation and bolted to each other. Two additional sections are placed and likewise bolted. The unit is bolted also to the foundation.

It will be appreciated that the present invention provides a modular dwelling unit constructed from a basic corner section. The comer section is designed so that a single module, a stacked double module, or an extended double module may be constructed from basic components.
