WWIZAQM 5 ATTORNEYS PREFABRICATED MULTI-STORY STRUCTURE This invention relates to a prefabricated building structure, and more particularly to a prefabricated two story building structure consisting of two or more modular units which are adapted to be fabricated at a manufacturing site, transported to a remote erection site, transferred onto a foundation and positioned in sideby-side relation, secured together and provided with a roof system, to provide a two story building structure ready for occupancy upon connection of the various utility lines. The invention further contemplates a novel two story modular unit which may be collapsed to reduce its height thereby facilitating its transportation from a manufacturing site to a final erection site.

In the building construction industry, there has been developed and extensively used, a technique for constructing building structures which consists of fabricating modular building units at a manufacturing site, hauling such units on vehicles to remote erection sites, transferring the units from the hauling vehicles onto a foundation at the erection site, securing the units together to form an integral building structure, and then connecting the electrical, water and sewage lines of the structure to appropriate utility lines. The use of such technique has enabled the employment of mass production methods in the fabrication of building structures, thus providing increased economy, improved product quality and reduced construction time.

Since prefabricated modular units must be transported over public highways from a manufacturing site to remote erection sites, one of the principal limiting factors in the design of such structures has been the restrictions on the size of the component modular units, either imposed by municipal, county or state governments, or dictated by highway conditions such as road and tunnel widths, clearance heights of underpasses and the like. Generally, municipal, county and state governments have enacted traffic regulations restricting the height, width and length of any unit transported over public highways.

The height limitations imposed by statute, has had the effect of limiting the prefabricated building industry to the manufacture and sale of single story structures, except in those instances where single story modular units are arranged in stacked relation to provide a multi-story structure. The practice of stacking one story modular units, however, has been found not to be entirely satisfactory in that additional costs are incurred in the additional handling required in transporting the modular units from the manufacturing site to the final erection site, and in transferring the additional units from their hauling vehicles onto other single story units.

Accordingly, it is the principal object of the present invention to provide a novel prefabricated building structure.

Another object of the present invention is to provide a novel prefabricated building structure consisting of two or more prefabricated modular units secured together to form an integral building structure.

A further object of the present invention is to provide a novel prefabricated multi-story building structure consisting of two or more prefabricated modular units secured together in side-by-side relation to form an integral rnuIti-story building structure.

A stillfurther object of the present invention is to provide a novel prefabricated multi-story building structure consisting of two or more modular units which may be fabricated at a manufacturing site, and transported to a remote erection site and secured together, to form an integral building structure.

Another object of the present invention is to provide a novelprefabricated multi-story building structure consisting of two or more multi-story modular units fabricated at a manufacturing site and transferred to a remote erection site to be secured together to form an integral multi-story building structure, wherein the modular units are provided with widths, lengths and heights which fall within permissible dimensional limitations imposed by municipal, county and state governments with respect to the size of objects hauled over the public highways. I

A further object of the present invention is to provide a novel prefabricated, multi-story modular unit.

A still further object of the present invention is to provide a novel multi-story modular unit which may be fabricated at a manufacturing site utilizing mass production methods and techniques, and transported to a final erection site and secured to one or moresimilar units on a foundation, to provide an integral multi-story structure.

Another object of the present invention is to provide a novel prefabricated modular unit having a permanent lower story and. a collapsible upper story which may be collapsed to reduce the height of the unit for transportation over public highways, which may be assembled in an upright position, secured to a similar upper story section of a similar modular unit,'and provided with a roof system, to provide an integral two story building structure.

A further object of the present invention is to provide a novel prefabricated modular unit having a permanent lower story section and an upper collapsible section, which is simple in construction, comparatively inexpensive to manufacture, and readily adapted to be moved to a final building site as a component of an integral two story building structure.

Other objects and advantages of the present invention will become more apparent to those persons having ordinary skill in the art to which the invention pertains, from the following description, taken in conjunction with the accompanying drawings, wherein:

FIG.-l is a perspective view of an embodiment of the invention, having portions thereof broken away;

FIG. 2 is a perspective view of a modular unit forming a part of the embodiment shown in FIG. 1, illustrating an upper story section disposed in a collapsed or inoperative position;

FIG. 3 is anenlarged, vertical cross-sectional view of the embodiment illustrated in FIG. 1;

FIG. 4 is a view similar to the view shown in FIG. 3, illustrating the upper story sections of the embodiment in their collapsed or inoperative positions, and the roof section in exploded relation;

FIG. 5 is an enlarged cross-sectional view taken along line 5,5 in FIG. 1; and v FIG. 6 is an enlarged cross-sectional view taken along line 6,6 in FIG. 3.

Briefly described, the present invention relates to a prefabricated multi-story building structure generally consisting of at least two modular units rigidly secured together to provide an integral structure, each of the modular units including a permanently constructed lower story section, and a collapsible upper story section mounted on the lower story section, the upper story section having at least one interior junction wall hingedly connected to the lower story section and movable between an inoperative, substantially horizontally disposed position, and an operative, substantially vertistantially horizontally disposed positions and operative,

substantially vertically disposed positions, and a roof section mounted on the upper story sections when the interior and exterior walls thereof are disposed in their operative positions.

In the preferred embodiment of the invention, the hinge axes of the interior and exterior walls lie at different levels to permit the walls to lie substantially horizontally in overlapping relation when the walls are disposed in their inoperative positions, the interior walls consist of frame assemblies having interior finishes applied thereon, the exterior walls consist of frame assemblies having interior and exterior finishes applied thereon, and the roof section consists of a plurality of transversely disposed, longitudinally spaced trusses seated on the exterior and interior walls, and roofing applied to the trusses.

Referring to the drawings, there is illustrated an embodiment of the invention. The embodiment consists of a prefabricated building structure formed from a The exterior end walls 19 are substantially similar in construction, each'consisting of a frame assembly including a transversely disposed bottom plate hingedly connected to a support plate 26 mounted on an upper end of the lower story section 14, studing 27 secured to the-lower plate 25 and a top plate 28 secured to the upper ends of the studing 27, an interior finish applied to the inner side of the frame assembly, an exterior finish applied to the outer side of the frame assembly and insulation disposed within the frame assembly between the studing. The exterior and interior finishes and the insulation applied to the frame assembly for the exterior end wall 19 is not shown in order to more clearly illustrate the construction of the frame assembly. It is to be understood, however, that the interior finish may be of any conventional type including sheet rock, wood panelling and the like, the exterior finish may be of any conventional type including wood or aluminum siding, wood or snythetic panelling, and the like, and the insulation can be of any suitable type. It is contemplated that the exterior finish, however, would most likely include sheathing applied to the frame assembly, a layer of weatherproofing material applied to the sheathing, and wood siding applied to the felt material and nailed to the sheathing and frame as sembly.

The bottom plate 25 is hingedly connected to the support plate 26 by means of strap hinges 29. The hinge connections of the exterior end walls 19,19 permit the pair of substantially similar modular units'11 and 12 1 disposed in side-by-side relation, and a. roof unit 13 mounted on the modular units 11 and 12, rigidly secured together to form an integral two story building structure. The modular unit 11 consists of a lower story section 14 provided with a conventional floor system,

a plurality of exterior walls 15 mounted on the floor system, and an interior junction wall 16, and an upper story section 17 which is connected to the upper end of the lower story section 14. Similarly, the modular unit 12 consists of a lower story section 14a provided with exterior walls 15a and an interior junction wall (not shown) engageable with the interior junction wall 16 of modular-unit 11, and an upper story section 17a.

The upper story section 17 includes a longitudinally disposed, interior junction wall18, a pairof transversely disposed, longitudinally spaced exterior end walls 19,19 and a longitudinally disposed, exterior side wall 20 which is spaced from the interior junction wall 18. The interior wall 18 consists of a frame assembly including a longitudinally disposed bottom plate 21 hingedly connected to the upper inner edge of lower story section 14, by means of strap hinges 22, studing 23 and a top plate 23, and an interior finish applied to the frame assembly, which is not shown. The interior finish applied to the inner side of the frame assembly for interior wall 18, can be of any conventional type including rock sheet, wood panelling and the like. The hinged connection of the interior wall l8-permits the wall to be pivoted downwardly into an inoperative position,'resting on the upper end of lower story section 14, as illustrated in FIGS. 2 and 4, and swung upwardly to an operative, upright position, as illustrated in FIGS. 1, 3 and 5. I

walls to be swung downwardly into inoperative positions resting on the interior wall 18, when the interior wall is resting on the upper end of the lower story section 14, as illustrated inFlGS. 2 and 4, and swung upwardly into an operative, upright position, with the bottom plates 25 seated on the support plates 26, as illustrated in FIGS. 1, 3, 5 and 6. As best illustrated in FIGS'. 5 and 6, the axes of strap hinges 29 lieat a level above the level of the axis of strap hinges 22, so that when the interior wall 23 is swung downwardly into its inoperative position resting on the upper end of the lower story section 14, the exterior end walls 19 may be swung downwardly into their inoperative positions, resting on the interior wall 18 thereby permitting the exterior end walls 19 to lie horizontally, without being obstructed by the interior wall 18.

The exterior wall 20 consists ofa frame assembly provided with a-plurality of transversely disposed, longitudinally spaced sections 30, an interior finish (not shown) applied to the inner side of the frame assembly, and an exterior finish 31 applied to the outer side of the frame assembly. Each of the frame sections 30 includes a vertical frame member 32 hingedly connected to a longitudinally disposed, raised section of i the lower story section 15, by means of strap hinges 33, a laterally projecting,bottom frame member 34 secured to the lower end of frame member 32, by means of nail plates 35, a laterally inclined frame member 36 interconnecting the ends and secured to the frame members 32 and 34, by means of nail plates 37 and 38, an inwardly projecting beam 39 secured to the lower end of the frame member 36, and a beam 40 interconnecting the inner end of the beam 39 and the bottom frame member 34 41 applied to the lower ends of the frame members 36 and the beams 39, and a longitudinal strip 42 applied to the inner ends of the beams 39 and the beams 40.

The exterior finish 31 may consist of conventional siding including wood or aluminum siding, panelling consisting of wood or a synthetic material, and the like, or may consist of conventional roofing including sheathing applied to the frame members 36, a layer of felt or similar material applied to the sheathing, and courses of shingles applied to the layer of felt.

As best illustrated in FIGS. 2, 4 and 5, the axis of strap hinges 33 is disposed at a level above the level of the axes of strap hinges 29 so that when the interior wall 18 and the exterior end walls 19 are swung downwardly into their inoperative positions, the exterior side wall may be swung downwardly and rested in an inoperative position on the exterior end walls 19,19, as illustrated in FIGS. 2 and 4, and swung upwardly to an operative, upright position, as illustrated in FIGS. 1, 3 and 5. V

The construction of the second story section 17a is similar to the construction of the second story construction 17, and includes an interior wall 18a, exterior end walls 19a, 19a, and an exterior side wall 20a which may be swung downwardly into inoperative positions, overlying the upper end of the lower story structure 14a and swung upwardly into operative, upright positions as illustrated in FIGS. 1 and 3, with the interior wall 18 abutting the interior wall 18 of modular unit 11. I The roof unit 13 is adapted to be applied to the upper story sections 17 and 17a in the field when the interior and exterior walls of the upper story sections 17 and 17a are rigidly secured in their operative, upright positions. The roof unit specifically consists of a plurality of transversely disposed, longitudinally spaced trusses 43 seated on and rigidly secured to the upper ends of the interior and exterior walls of the upper story sections 17 and 17a, and roofing applied to the trusses. As

best illustrated in FIGS. 3 and 4, each of the trusses 43 includes a bottom chord member 44 adapted to be seated on and secured to the walls of the upper story sections, a pair of diagonal, top chord members 45 and 46 vertical components 47, 48 and 49, and diagonal chord members 50 and 51. The trusses 43 are adapted to be secured together by conventional blocking when mounted on the walls of the upper story sections. The roofing applied to the trusses may be of any conventional type, and most likely would consist of sheathing applied to the top truss chord members 45 and 46, a layer of felt or similar material, and courses of shingles.

The modular units 11 and 12 are prefabricated at a manufacturing site utilizing mass production methods and techniques. When the units have been completed, the walls of the upper story sections are collapsed into their inoperative positions for shipment. This is accomplished with the interior modular unit 11 by swinging the interior wall 18 downwardly so that it comes to rest on the upper end of the lower story section 15, swinging the exterior end walls 19,19 downwardly so that they rest on the collapsed interior wall 18, and then swinging the exterior side wall 20 downwardly so that it rests on,the collapsed exterior end walls 19,19. The upper story section 17a of modular unit 12 is collapsed in a similar manner. I

When the second story structures of the modular units have been collapsed in their inoperative positions, providing compact units of minimum width and height,

' and 18a will be secured in abutting relation, exterior.

the units are loaded on trailers or dolleys and hauled along with aset of trusses 43 and roofing material, to an erection site provided with a foundation. The units 11 and 12 are then transferred onto the foundation and positioned in side-by-side relation. After the units have been positioned, they are rigidly secured together to complete the first story of the structure. Next, the exterior side walls 20 and 20a, the exterior end walls 19 and 19a, and the interior walls 18 and 18a are swung upwardly into their operative, upright positions, and rigidly secured together. With the walls of the upper story section in their upright positions, the interior walls 18 end walls 19 and 19a will be disposed in transverse alignment and exteriorside walls 20 and 20a will be disposed in spaced parallelrelation to the interior walls 18 and 18a.

After the second story structure has thus been assembled, the trusses 43 are set on the upper end thereof, and the roofing is applied to the trusses. To complete the structure, a ceiling, additional partition walls, and various fixtures may be installed'in the second story structure, and the water, sewage and electrical outlets may be connected to appropriate'utility lines. With the structure thus assembled, it would be ready for immediate occupancy. i

The interiors of the modular units of 11 and 12, are

completely finished at the manufacturing site, so that upon securing the unit together and assemblying the roof system at the, construction site, a minimum amount of work is required to complete the structure in the field. It is contemplated that the interior of the lower story sections of the modular units be provided with conventional partition walls, sheet rock and panelling applied to the interior walls, and conventional floor coverings including hardwood, resilient tile and ceramic tile. The units further would be provided with kitchen cabinets and appliances, bathroom cabinets and fixtures, lighting fixtures, and electrical, heating and plumbing systems.

' In the embodiment as described, it will be noted that there is provided a prefabricated two story building structure in which the structure is formed of at least two modular units which can be packaged in compact units having widths and heights falling within perrnissi- I ble limits imposed by law with respect to the hauling of such units over the public highways. The design of the unit combines the advantages of utilizing mass production methods and techniques for fabricating the modular components of the building structure, and providing a finished product which is comparable in quality and aesthetic appeal to multi-story building structures erected entirely at a building site.

The prefabricated multi-story building structure as described, eliminates the additional handling and alignment normally required in erecting conventional multi-.

a modular unit with a collapsible upper story positioned on a conventional single story modular unit to provide a three story structure which can be combined with similar three story structures to provide garden type apartments or town house's.

From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention which come within the province of those skilled in the art. However, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the appended claims.

I claim:

1. A modular unit adapted to be positioned in sideposed longitudinally, and the exterior walls include a pair of end walls having transversely disposed, longitudinally spaced "hinge axes disposed at a level higher than the hinge axis of said interior junction wall, and a side wall having a longitudinally disposed hinge axis disposed at a level higher than the level of the hinged axes of said end walls.
