DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention is a type of basic building or structural element and a plurality of these structural elements that can be easily interconnected to create a system of structural elements and more complex structure. The interconnected structural elements can be connected and configured to make a wide variety of three-dimensional structures, including from a simple triangle, or cube, to a much more complex lattice/bridge structure, or geodome structure.

As shown in FIG. 1, each structural element may be, in a preferred embodiment, a relatively flat piece. The structural element 10 has two pair of substantially parallel opposing sides. Moreover, as shown in FIG. 1 and FIG. 2, each structural element 10 has a flexible hinge section 3 such that each structural element 10 has two sections 2a and 2b, and may be folded onto itself into an essentially flat element. The three sequential drawings of FIG. 2 show an end view of the structural element in a fully open configuration, a partially closed configuration, and lastly, a fully closed, or folded configuration.

A preferred embodiment of the hinge section 3 has the section configured with high flexibility, often called a “living hinge.” A living hinge 3 can be opened and then closed so that side by side surfaces 2a, 2b in an open position can be folded to be adjacent to each other and touching in both directions.

The structural elements 10 can be manufactured from a wide variety of materials. Examples include, without limitation, paper, card board, plastic, wood, concrete, masonry, metal, paneling, drywall, ceramics. The hinge sections can similarly be manufactured from many different materials, including paper, tape, plastic, vinyl, metal, wire, rebar, chain, string, rope, or cable.

Each structural element 10 also has connecting means along each of the sides of the elements 10. In a preferred embodiment, as shown in FIG. 1, interconnecting male 7 and female 8 sections may be formed along opposing sides. Similarly, as also shown in FIG. 1, alternative male or T-shaped sections 4, may be configured to connect with female end sections 5 and 6. The ability to interconnect the structural elements 10, end to end is illustrated in FIGS. 3A, 3B, and 3C, showing the connection of T-shaped section 4 into female end sections 5, 6.

By interconnecting a plurality of structural elements 10, along both the sides using interconnecting male 7 and female 8 sections, and end to end using male 4 and female 5, 6 sections, a wide variety of three dimensional shapes 100 may be quickly configured. FIG. 4 shows an example of a triangular prism configuration. A more complex shape, such as interconnecting two triangular prisms is shown in FIG. 5.

Another basic example of a structure created from a system of the core building elements is a cube shape formed by connecting of twelve rectangular or quadrilateral elements. As shown in FIG. 6, the building element are partially folded, to an approximate right angle and then each of the building elements are connected to two other building elements at a respective edge.

By adding further structural elements, more complex shapes can be easily constructed. More particularly, and as shown in FIGS. 7, 8 and 9, spherical shaped structures easily assembled. In each of the structures shown in FIGS. 5 through 9, the core elements of the hinged building structure system are a plurality of substantially flat and substantially rigid structural elements 10, and a plurality of flexible hinge sections 3 that are connected to each other through the male and female interconnecting sections. As noted, the hinge sections should be sufficiently pliable to permit the structural elements to fold upon each other in the fully-collapsed configuration.

Another preferred embodiment of a structural element 10 is shown in FIG. 10. In this preferred embodiment, each structural element is also a relatively flat piece, with a flexible hinge section 3 such that each structural element 10 may be folded onto itself into an essentially flat element. The structural element 10 shown in FIG. 10 has a series of notches 20 that can be used to connect structural elements side to side in an essentially perpendicular configuration as illustrated in FIG. 16.

As also shown in FIG. 10, the end interconnecting elements have a different shape and configuration. The male section is formed of two pieces 15 with a slot 21 between the two pieces 15. The female section is also formed of two wider spaced pieces 11 with an opening and a slot 22 located between the two pieces 11. FIGS. 11 and 12A, 12B, and 12C show how this embodiment of structural elements 10 may be easily interconnected end to end by linking the two male pieces 15 in between the two female pieces 11.

By partially folding the structural elements 10, and connecting the end sections of the structural elements together, various frame structures can be easily assembled. FIG. 13 shows three structural elements about to be interconnected end to end to form an apex of structure. Similarly, FIGS. 14 and 15 show respectively four and five structural elements being interconnected to form alternative corner sections of three-dimensional structures. However, the structural elements need not be folded to interconnect and form three dimensional structures. As shown in FIG. 18, the end pieces 11 and 15 can be interconnected to form a triangle shape, or by adding another structural element, a square shape can be assembled (not shown).

Using the FIG. 10 embodiment, the structural elements 10 can be connected to form longer elements, as shown in FIG. 17 by using slots 21 and 22 located between end pieces 11 and 15.

As described above, the collapsible building structure system, using larger size structural elements, could be used to create more utilitarian structures. For example, FIGS. 19, 20, 21, and 22 show a variety of frames which could be base structures for a house or shed. In FIG. 19, cube form with a prism form on top which could be the simple frame for a house. In this configuration, the structural support members for a house, tent or shed could be quickly assembled. Such structures could be used for temporary housing for victims of natural disasters, such as floods, earthquakes or fires. Such temporary housing or safe structures can be easily transported in the compact folded configuration, and then quickly put into place and finished once the support structure is un-folded and assembled. Roofing and siding materials similarly can be quickly installed to created a sealed and protective structure.

More complex structures and shapes can be easily created by adding more structural elements. FIGS. 23 through 30 show a series photographs of various three dimensional structures formed from the inventive structural elements 10. FIG. 23 shows a double helix model formed from a preferred embodiment of the structural elements. In this model and structure, the structural elements are not folded, but are interconnected using the side notches 20. FIG. 24 is a relatively complex example of an icosahedron/dodecahedron form using sixty structural elements. FIG. 25 shows a more intricate example of a dodecahedron form from triangular sections using ninety structural elements. A type of a “bucky ball” is shown in FIG. 26 by connecting nine structural elements end to end to from triangular shapes, and then interconnecting the ends of the triangular shapes to form the “ball” shape.

Another spherical shape is shown in FIG. 27 formed from twenty tetrahedron configurations and then interconnected to form another dodecahedron. The FIG. 27 structure was formed from one hundred twenty structural elements 10. FIG. 28 shows another example of a dodecahedron formed from 240 structural elements 10. Different building shapes can be interconnected as shown in FIG. 29 where six octahedrons are interconnected to eight tetrahedrons. As another example of a complex building structure, FIG. 30 shows a lattice design formed from octahedrons and tetrahedrons. In this configuration, the three dimensional structure can be used as a frame for a bridge or ladder. As such, the hinged structural elements 10 can be used to assemble the frame system for many products, buildings and other constructs such as dams, bridges, towers, space stations and other possible built environments.

The series of drawings shown in FIGS. 31 through 39 show an example of a cube structure starting in the fully folded state, FIG. 31, then sequentially being unfolded into the completely open cube, FIG. 39. The cube shape may thus be easily collapsed without disassembly of the system of elements, such that in the completely collapsed condition, the system of elements is relatively flat, allowing for ease of storage and portability. Accordingly, the structural elements provide a means of creating a collapsible building structure system that can be, in different embodiments, used as a toy-type object for children or adults, or can be used, in larger configurations, as building elements for full-sized buildings, sheds, tents, bridges, or other similar structures. Particular features of the structural element system is that in a fully-collapsed configuration, the system can be substantially flat, while in a fully un-folded configuration, the system is a three-dimensional structure that can be as simple as a triangle, to as complex as, for example, a dodecahedron. One advantage of such a collapsible structure building system is easy of storage and transporting of building elements when the structures are in a fully-collapsed or disassembled configuration.

As described, the inventive collapsible hinged building structural system provides a system for disassembling and collapsing a system of elements into a substantially flat structure, and then, in an un-folded and assembled configuration, having a full three-dimensional structure that can be a toy object, a decorative piece, or a full structure which can be used for buildings, housing, or bridge sections.

The above detailed description teaches certain preferred embodiments of the present inventive building element device and system of interconnectable building elements. The building element device, including the hinge section and interconnecting elements, allows for the construction of various three-dimensional structures using a plurality of the element devices. The building element devices can be easily transported in their flat and compact configuration. Once constructed into a variety of structures, the system of element devices can be easily collapsed into a relatively flat and compact configuration, again for ease of transportation or storage. While preferred embodiments of the building elements have been described and disclosed, it will be recognized by those skilled in the art that modifications and/or substitutions are possible and such modifications and substitutions are within the true scope and spirit of the present invention. It is likewise understood that the attached claims are intended to cover all such modifications and/or substitutions.
