Description:

BACKGROUND

This invention relates to improvements in the quick, inexpensive, lightweight and strong, construction of large enclosures from relatively small, thin, stackable, polyhedral parts, connectors and hinges to result in a virtually unlimited variety of shapes, sizes, and functions of instant, polyhedral enclosure assemblies, by hand, without the use of tools.

More specifically, the present invention relates to an innovation in the way clear, translucent and opaque polyhedral construction elements can be instantly connected together resulting in assemblies of infinite shapes, sizes and functions. The present invention provides the means for assemblies of connectors and polygons which can be hand assembled without tools within a few seconds per module. Additionally, in a variety of applications, the polyhedral elements can be connected together in a hinged manner in order to allow entry and exit into and out of structures and enclosures created with the components of the system. Additionally, in a variety of applications, the polyhedral elements can be connected together with anchors, bolts, foundations, stakes, pins, or other connections to the ground to provide a secure enclosure, shelter or structure with wind, rain and other element protection. Additionally, in a variety of applications, the polyhedral elements can be connected together with other existing structures to enlarge and enclose additional cubic space.

When the first built structure becomes obsolete, the components can be disassembled by hand, without the use of tools, and then reassembled to create other structures at will.

BRIEF HISTORY

The building industry of today comprises substantially conventional site grading, concrete foundation, wood frame or steel frame, nails, Plywood, drywall, screws, stucco, shingles, tiles, glass, paint and finish construction practices. All of these building techniques are very time consuming, require large numbers of skilled tradesmen, are generally very expensive, require large numbers of expensive tools, and are generally considered permanent until the building is torn down.

With the innovation contained in this patent, it is now possible to construct instant polygon structures such as geodesic domes, spheres, polyhedrons, pyramids, cubes, trapezoids, arches, columns, walls, roofs, ceilings, conduits, tunnels, vents, windows, doors, or any combination thereof in order to construct buildings, houses, enclosures, swimming pool covers, furniture, partitions, tables, counters, railings, tents, exhibits, cabinets, toys, sheds, barns, aircraft hangars or other types of enclosures or shelters by hand, without the use of tools, inexpensively and quickly without skilled labor. Polyhedron Structures such as those created utilizing the geodesic dome invention of Richard Buckminster Fuller as disclosed in U.S. Pat. No. 2,682,235 in 1954 have enclosed more cubic space, using less building material, than any other architecture in history according to the Fuller web site in 2001. The entirety of Richard Buckminster Fuller's expired U.S. Pat. No. 2,682,235 is hereby incorporated by reference into this specification. R. Buckminster Fuller was one of my instructors at the Art Center College of Design in Pasadena Calif. in 1978-79. Even though his invention of the geodesic dome was truly an astounding innovation, he often complained of how difficult, expensive and time consuming it was to build geodesic structures to the tight tolerance angles and exacting beam length dimensions needed to execute a symmetrical and accurate structure as planned. The problem with geodesic structures as they existed before the current invention is that small errors in each of the components of a geodesic dome containing hundreds or thousands of components results in multiple small errors adding up to large errors over a large structure. The current invention eliminates these problems by using a manufacturing process that results in hundreds or thousands or millions of identical construction parts having little or no errors in their dimensions and properties.

SUMMARY OF THE INVENTION

A modular construction system consisting of a plurality of multifunction connectors or multifunction hinges joining together a plurality of polyhedral panel components having edge connector engaging means resulting in a spring tensioned, automatic parabolic, self-aligning, perpendicular snap-in, parallel slide out, planar angle tolerant, rotational angle tolerant, toe-in angle tolerant, toe-out angle tolerant, easy-in/hard-out, dual reverse curl linear barb, multi-planar, centerline pivoting, centerline friction, dual edge sealing, pre-stressed assembly creating groups of connected polyhedron modules forming a virtually unlimited variety of domes, arches, spheres, cylinders, cubes, trusses, walls, roofs, hinges, doors, windows, columns, beams, bridges, frames, vaults, fixtures, enclosures, shelters, partitions, toys, covers, sculptures, containers, stairs or other polyhedral structures, by hand, without the use of tools using only seconds of construction time per module. When the first built structure becomes obsolete, the components can be disassembled by hand, without the use of tools, and then reassembled to create other structures at will.

GENERAL DESCRIPTION OF THE INVENTION FUNCTION

The present invention functions as an instant enclosure construction system for creating polyhedral structures of a virtually unlimited number of sizes, shapes and uses.

The function of the current invention is easy enough for an average child of three years old to assemble into simple combinations. In fact, one embodiment of the invention function is that of a child's construction kit toy. This toy would be made up of hand sized, polyhedron shaped panels made of clear, translucent, or opaque panels having edge engagement means for removably attaching to each other with multifunction connectors and hinges to result in polyhedral assemblies such as castles, forts, houses, arches, pyramids, domes or a wide variety of other structures that the kids themselves could move inside of for any variety of roll playing games they could imagine. When the kids become bored with the first structure, they can simply disassemble and create other structures at will.

Larger modular sizes of the polyhedral construction kit would be well suited for adults to quickly, inexpensively and efficiently construct clear, translucent, or opaque panels having edge engagement means for removably attaching to each other by attaching multifunction connectors and hinges to result in polyhedral assemblies such as storage sheds, patio enclosures, swimming pool covers, greenhouses, garages, temporary shelters or permanent shelters.

Extremely large modular sizes of the polyhedral construction kit would be well suited for professional builders to quickly, inexpensively and efficiently construct clear, translucent, or opaque panels having edge engagement means for removably attaching to each other with multifunction connectors and hinges to result in polyhedral assemblies such as sports stadium domes, outdoor concert venue covers, airport terminal covers or other temporary or permanent large structures.

Although the present invention has been described in terms of specific embodiments, it is anticipated that alterations and modifications thereof will no doubt become apparent to those skilled in the art. It is therefore intended that the teachings and drawings that comprise the content of this patent application as well as the following claims be interpreted as covering all such alterations and modifications as fall within the true spirit and scope of the teachings and drawings contained herein as well as the true spirit and scope of the invention claims and the invention itself.

OBJECTIVES OF THE PRESENT INVENTION

The first objective of the present invention is to provide a modular construction system consisting of a plurality of multifunction connectors or multifunction hinges for permanently or temporarily joining together a plurality of polyhedral panel components having edge connector engaging means resulting in groups of connected polyhedron modules forming a virtually unlimited variety of polyhedral structures.

The second objective of the current invention is to provide a spring tensioned connection between polyhedral panels comprising a modular polyhedral structure construction system. In one application, this spring tensioned connection could utilize a molded or extruded elastimeric material which would provide a controlled elasticity between polyhedral panels which would provide for the variation in angles of adjacent polyhedrons necessary to form a wide variety of parabolic radius, angular and edge length dimensions of geodesic domes, arches, spheres, cylinders, ovals or other faceted or radiused polyhedral structures, enclosures or objects.

The third objective of the invention is to provide a spring tensioned, elastimeric polyhedron connector function that creates an automatic parabolic dome forming connector option wherein the connector is provided with a pair of opposite polyhedral edge engaging means which are formed at an angle other than flat which place two adjacent polyhedrons into a peak or an oblique angle in relationship to each other. This spring tensioned angle causes multiple connected groups of polyhedrons to automatically form into a convex or dome like shape. The spring tension angles of connection causes the faceted polyhedrons to cooperate with one another to spring into a more parabolic, more spherical structure which adds more structural strength to the exterior surface to improve wind resistance and snow load performance.

The fourth objective of the present invention is to provide an automatic, self aligning function. The connectors are provided with elastimeric, self centering means with which to automatically align the edges of the polyhedron components with the ideal connector location in order to make the construction of the components of an application of the connectors with the polyhedral elements simple, convenient, automatic and relatively effortless.

The fifth objective of the spring tensioned, elastimeric polyhedron connector is to provide a perpendicular snap-in/parallel slide out, assembly and disassembly function. In the preferred embodiment of the current invention, each edge of the polyhedrons to be connected would be provided with linear barb means necessary to engage the spring tensioned, elastimeric, polyhedron connector in a manner which allows the edge to be forced into the multifunction slot of the connector in a perpendicular snap-in fashion. Once engaged, the edge would be difficult, if not impossible with reasonable force limits, to pull out the same way as it went in causing a positive lock. This positive lock could be disassembled by utilizing a parallel slide out method. Both the perpendicular snap-in/parallel slide out methods of assembly and disassembly are simple, convenient and relatively effortless while providing strong mechanical functions.

The sixth objective of the invention is to provide angle variation tolerance between structural components. In the past, large geodesic dome structures required exacting dimensional polyhedral frame components in order to result in a single parabola, symmetrical dome structure. In the past, any variation from the planned geometry would result in small errors in each component multiplied times the large number of components to result in a potential for a large total error compilation which could create asymmetrical or unplanned multiple parabola dome structures. The current invention utilizes connectors with automatic angle variation tolerance and averaging functions to effectively average the angles between polyhedrons and spring tension to adjust the polyhedrons into the optimal orientation to produce single parabola and symmetrical dome structures. This spring tensioned, elastimeric polyhedron connector provides planar angle tolerant averaging, rotational angle tolerant averaging, toe-in angle tolerant averaging, toe-out angle tolerant averaging, by automatically placing balanced averaging forces on each component of a group of components to result in structures with polyhedron components spring tensioned into the optimal position for symmetrical and single parabola dome structures.

The seventh objective of the spring tensioned, elastimeric polyhedron connector is to provide a dual conical, dual reverse curl, linear elastimeric barb system of polyhedron connection. This system provides an easy-in/hard-out method of polyhedron assembly and disassembly. When the edge of a polyhedron with linear barb engaging means is pressed into the spring tensioned, elastimeric polyhedron connector, the dual conical, dual reverse curl, linear elastimeric barb system spreads open along the inclined plane wedge features of the polyhedron linear barb engaging means allowing the polyhedron barbs to enter the elastimeric spring tension trap. Once inside the connector trap, the dual reverse curl, linear elastimeric barbs snap closed behind the polyhedron barbs locking the connector and polyhedron together. The harder the pull on the polyhedron, the tighter the dual reverse curl, linear elastimeric barbs engage the connection. This connection is very strong in a perpendicular direction for structural strength. This connection is very weak in a parallel direction allowing the easy disassembly of components for knock down transport and compact storage. Alternatively, the construction system can be assembled and disassembled using a parallel slide-in/parallel slide-out method which does not rely on the elastomeric flexibility of the connector to allow entry into the multifunction slot. With the parallel slide-in/parallel slide-out method of assembly and disassembly, the connector can be formed of stiffer or extremely stiff material for greater strength load bearing connections made of metals, composites, woods, glass, concrete, stone, acrylic or other stiff material.

The eighth objective of the invention is to provide multi planar connection of two or more polyhedrons with a single connector. The preferred embodiment connector provides for four polyhedrons to share a common connector at a variety of angles. Other embodiments may include a one, two, three, five, six or more multi planar connector system. This multi planar system of connectors allows for the construction of truss braces, multiple layer composite structures and containers or conduits within the overall structure of a building construction.

The ninth objective of the spring tensioned, elastimeric polyhedron connector is to provide connector lengthwise centerline pivoting and friction points which are coincident with the centerline of the edge of each polyhedron. By providing pivot and friction points coincident in the centerlines of both the connectors and the polyhedrons, the polyhedron angle variations may be divided exactly in half resulting in the highest geometric dimensional accuracy in domes, arches or other polyhedral structures involving hundreds of components. By placing the pivot and friction points on the centerline of the connector, the polyhedron edges are substantially centerline fixed, locked and controlled while the polyhedron edge ends are allowed to move within a spring tensioned angle tolerance and averaging system that uses each polyhedron's position to effect the location and spring tension of adjacent polyhedrons automatically.

The tenth objective of the present invention is to provide a dual edge sealing function between the connectors and the polyhedrons to provide a weather seal and trapped air insulation function between the inner and outer seal. If the structure is to be semi-permanent and rain protection is important, the multifunction slots of the connectors may be pre-filled with a silicone or elastomeric, weather sealing, caulking material before assembly of the polyhedrons. The dual conical, dual reverse curl, linear elastimeric barb system is an ideal container for the caulk sealant because the pressure of insertion of the polyhedron into the connector causes backpressure to form on the linear barb edge engagement system which causes the caulk to immerse the entire interface area between the connectors and the polyhedrons to form an excellent seal when the caulk sealant solidifies. Additional sealant material or an insert plug or screw applied or attached at the corner intersections of the polyhedrons and connectors would provide a completely waterproof enclosure shelter.

The eleventh objective of the present invention is to provide a method of securely attaching the polyhedron constructions to the ground or to other structures with anchors, bolts, foundations, stakes, pins, or other connections provide a secure enclosure, shelter or structure or to enlarge and enclose additional cubic space within a structure or to provide wind, rain and other element protection.

The twelfth objective of the spring tensioned, elastomeric polyhedron connector system is to provide a parallel slide-in/parallel slide-out, assembly and disassembly function. In the preferred embodiment of the current invention, each edge of the polyhedrons to be connected would be provided with linear barb means necessary to engage the spring tensioned, elastomeric, polyhedron connector in a manner which allows the edge to be slid into the multifunction slot of the connector in a parallel slide-in fashion. Once engaged, the edge would be difficult, if not impossible with reasonable force limits, to pull out in a perpendicular direction causing a positive lock. This positive lock could be disassembled by utilizing a parallel slide-out method. Both the parallel slide-in/parallel slide-out methods of assembly and disassembly are simple, convenient and relatively effortless while providing strong mechanical functions.

The thirteenth objective of the present invention incorporates multi walled or inflated polyhedral panel sections made up of transparent, translucent or opaque material with linear barb edge means for engaging multifunction, elastomeric or plastic, snap-in/slide-out or slide-in/parallel slide-out, connectors which result in an insulated sealed enclosure.

The fourteenth objective of the present invention provides the means for assemblies of connectors and polygons which can be hand assembled without tools within a few seconds per module. This construction system, which does not rely on tools to effectively accomplish either the perpendicular snap-in/parallel slide-out or the parallel slide-in/parallel slide-out, polyhedral construction assembly and disassembly functions, adds a level of convenience heretofore not possible with any other sealed, geodesic, polyhedral construction system.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 is a perspective view of the preferred embodiment building system utilizing a plurality of 3 triangle polyhedral panels joined together by a plurality of 12 two panel dome connectors to form a geodesic dome structure having sealed edges and intersections which automatically form during the assembly process.

FIG. 2 is a perspective view of the preferred embodiment 3 triangle polyhedral panel, 2 hinge polyhedral panel, 4 square polyhedral panel, 14 four panel radial connector and 5 pentagon polyhedral panel showing the disassembled aspects of the main components of the building system.

FIG. 3 is a perspective view of the preferred embodiment 3 triangle, 2 hinge, 4 square, 14 connector and 5 pentagon showing the assembled aspects of the building system FIG. 4a is a section view of the preferred embodiment connector showing the 12 two panel dome connector and the edge of the 4 square polyhedral panel before insertion. (The preferred embodiment shows a 12 two panel dome angle connector, however the connector could be designed to accept any number of polyhedral panels such as 3, 4, 5, 6, 7 or more.) FIG. 4b is a section view of the preferred embodiment connector showing the 12 connector and the edge of the 4 square polyhedral panel during insertion. As the edge of the 4 square polyhedral panel is pressed into any one of the 40 multifunction slots it spreads the 30 dual conical, dual reverse curl, linear elastomeric barbs open allowing the 60 polygon linear connector barb engagement means on the edge of the 4 square polyhedral panel initiating the entry of the 4 panel into the 12 connector.

FIG. 4c is a section view of the preferred embodiment connector showing the 12 connector and the edge of the 4 square polyhedral panel after insertion. Complete engagement of the connection has occurred, illustrated by the position of the 60 polygon linear connector barb engagement means inside the 40 multifunctional slot while being retained in a spring loaded, automatic aligning, fashion by the 30 dual conical, dual reverse curl, linear elastomeric barbs which has the secondary function of creating a spring loaded oblique angle orientation between one polyhedral panel and another sharing a connector.

FIG. 5 is a perspective view of the preferred embodiment 14 four panel radial connector illustrating the four 40 multifunction slots for removably accepting the edges of a maximum of four polyhedral panels.

Within each of the 40 multifunction slots is a 30 dual conical, dual reverse curl, linear elastomeric barb which has the purpose of allowing the engagement means on the edge of a polyhedral panel to enter the 40 multifunction slot and then to be trapped inside the slot by the elastomeric, reverse curl, barbs which do not allow the connection to be broken in a perpendicular direction with reasonable force.

Each connector has a 50 intersection tip which is formed into an angle oar conical shape, in this preferred embodiment, but a 50 intersection tip may also have a flange shape or a ring shape or a fin shape ore flap shape or a spiral shape or an overlapping shape or an elongated shape or a shortened shape or a pin shape or a snap shape or a screw shape or a threaded shape or a barbed shape or other shape for intersecting or adjacency or sealing or contacting or connecting to other connectors or other 50 intersection tip or tips at the intersections of the polyhedral assemblies formed by groups of polyhedral panels, connectors or hinges.

FIG. 6 is a perspective view of the preferred embodiment 22 two panel connector, 23 three panel connector, 24 four panel truss connector, 25 five panel connector and 26 six panel connector. Each of the connectors comprises a plurality of 30 dual conical, dual reverse curl, linear elastomeric barbs within a plurality of 40 multifunction slots. Each end of the connectors is provided with a tapered or conical and or overlapping or interlocking or snap fit or sealed 50 intersection tip. These intersection tips are shaped to intersect or overlap or connect or interlock or seal with other 50 intersection tips in order to provide a watertight or airtight or ventilated or perforated or semi-permeable or permeable or non-permeable or flexible or rigid or bearing intersection.

FIG. 7 is a perspective view of the preferred embodiment 3 triangle in combination with other 3 triangles and 14 connectors.

FIG. 8 is a perspective view of the preferred embodiment 4 square in combination with other 3 triangles, 4 squares and 14 connectors.

FIG. 9 is a perspective view of the preferred embodiment 5 pentagon in combination with other 5 pentagons and 14 connectors.

FIG. 10 is a perspective view of the preferred embodiment 2 hinge illustrating a plurality of 40 multifunction slots and 30 dual conical, dual reverse curl, linear elastomeric barbs or 32 dual tapered, dual square barbed, linear elastomeric barbs forming polyhedral panel retention slots that may utilize either the perpendicular snap-in/parallel slide-out or the parallel slide-in/parallel slide-out method of construction. The 2 hinge includes a preferred embodiment 34 flexible spring loaded hinge and a 36 door latch. When the 34 flexible spring loaded hinge is actuated in a direction that causes the 38 hinge movement gap to be contracted, the 36 door latch moves out of contact with the polyhedral panel acting as a door and the door can be opened. When the polyhedral panel acting as a door is closed, the entry of the door into the 36 door latch causes the 38 hinge movement gap to be contracted allowing the door to become seated in contact with the 34 flexible spring loaded hinge. In this position, the spring loading on the hinge causes the 36 door latch to contact the polyhedral panel acting as a door which effectively traps the door and holds the door shut until pivotal pressure is applied to the 34 flexible spring loaded hinge causes the 38 hinge movement gap to be contracted which opens the 36 door latch. When the 34 flexible spring loaded hinge is actuated in a direction that causes the 38 hinge movement gap to be expanded, the 2 hinge opens. The preferred embodiment 2 hinge shows an orientation where the hinge is positioned above a pair of polyhedron edge connectors which allow a double layer of polyhedron panels to be constructed wherein the hinged panel may pivot away from a second adjacent polyhedral panel without leaving a void in the overall structure made by the second polyhedral panel in combination with other polyhedral panels and connectors. Other hinge embodiments within the scope of the invention include a hinge that leaves an open void in a group of connected polyhedrons when the hinge is opened.

FIG. 11a is a section view of the preferred embodiment 2 hinge in combination with 4 square polyhedral panels illustrating the closed door position. The 38 hinge movement gap at the pivot hinge and at the opening hinge intersections are at the normal positions.

FIG. 11b is a section view of the preferred embodiment 2 hinge in combination with 4 square polyhedral panels illustrating the unlatched door position. The 38 hinge movement gap at the pivot hinge intersection is expanding to allow the door to open and the 38 hinge movement gap at the opening hinge intersection is contracted causing the 36 door latch to pivot open allowing the door to open.

FIG. 11c is a section view of the preferred embodiment 2 hinge in combination with 4 square polyhedral panels illustrating the open door position. The 38 hinge movement gap at the pivot hinge intersection is expanded and the door is open and the 38 hinge movement gap at the opening hinge intersection is in the normal position.

FIG. 12 is a top section view of the preferred embodiment 14 connector illustrating the spring loaded, angle tolerant, rotation tolerant, toe-in toe-out misalignment tolerant functions of the connectors in combination with polyhedral panels. The two 4 polyhedral panels are shown inserted into a 14 connector in a non-parallel alignment. This non-parallel alignment illustrates the ability of the connector to first allow unrestricted movement within the 40 multifunction slots until the spring-loaded action of the elastomeric connector snaps the polyhedral panels back into a controlled relationship with each other. The preferred embodiment 14 connector has a section which is characterized by a thicker section at the 45 connector longitudinal centerline than at the 50 intersection tip, this allows angular movement of the 60 panel engagement means portion of the polyhedral panels within a spring loaded angular tolerance area which provides elastomeric control of the polyhedral angles in relationship to each other. The 45 connector longitudinal centerline is also the friction point of contact and the pivot point for the 60 panel engagement means portion of the polyhedral panels.

FIG. 13a is an end section view of the preferred embodiment 14 connector illustrating the straight in perpendicular engagement orientation of four 4 polyhedral panels into each of four 40 multifunction slots including 30 dual conical, dual reverse curl, linear elastomeric barbs providing spring loaded, angle tolerant, rotation tolerant, out of plane misalignment tolerant functions of the connectors in combination with polyhedral panels.

FIG. 13b is an end section view of the preferred embodiment 14 connector illustrating the rotated out of plane, angular engagement orientation of the two lower 4 polyhedral panels into the lower two 40 multifunction slots including 30 dual conical, dual reverse curl, linear elastomeric barbs causing the elastomeric connector material to flex, compress and bend in a spring loaded fashion to accommodate angular movement of the polyhedral panels without disconnecting the polyhedral panel from the connector.

FIG. 14 is a perspective view of the preferred embodiment 3 triangles and 4 squares in combination with 24 four panel truss connectors and 26 six panel connectors in the construction of a multi-walled, insulated housing structure embodiment. Such a structure could be constructed within a few hours by hand without tools creating a permanent structure. If the structure were to be temporary, it could be disassembled by hand without tools within a few hours.

FIG. 15 is a perspective view of the preferred embodiment 3 triangles, 4 squares and 5 pentagons in combination with 12 two panel dome forming connectors and 14 dome forming connectors and 24 four panel truss connectors and 22 two panel straight connectors and 25 five panel radial connectors and 26 six panel radial connectors and 2 hinges to form the construction of a small variety of the virtually unlimited number of polyhedral toys that could be created using the current invention in a toy polyhedral construction kit application.
