BACKGROUND OF THE INVENTION




A significant advance in basic structural systems for stationary structures has not occurred since the advent of prestressed and reinforced concrete, structural steel, and the use of cable as a tensional element. There have been some innovative engineering and architectural advances, such as various types of folding structures, tube and ball and other space trusses and the dymaxion concept. However, none of these advances has escaped the use of conventional structural elements in compression, tension and flexion mode. Although there have been more recent developments in the field of vehicular structure, such as formed sheet rigidification, the fundamental methods have not changed significantly from the rigid rib, stringer, and truss design. The present invention is a significant advance in structural systems, both stationary and moveable, with respect to weight, strength, flexibility and magnitude.




There does not appear to be any prior art that his invention builds upon except generally in the field of structural engineering, none of which directly addresses structural combinations of toroidal elements.




The patent classification system does not contain a classification for structural systems as such, the most appropriate description of the present invention, but does address specific types of structures, such as “static structures” (Class 52), “bridges” (Class 14), “railway rolling stock” (105/396+), “ships” (114/65+), “aeronautics” (244/117+), “land vehicles bodies and tops” (296/) etc. There are also no classifications for structures which are dynamic in managing the stress of structural elements or for structures which can dynamically change shape or volume. The latter of these may be addressed to a certain extent in Class/Subclass 52/109, which allows for the extension and retraction of a structure by the use of pivoted diagonal levers, or in Class/Subclass 52/160, which covers closures and other panels made of flexible material, With respect to toroidal structural elements, no structural classification could be found. Therefore, at least with respect to the extent that the classification system may reveal such, there does not appear to be prior art described therein. However, there are some superficial graphic similarities involving shapes and forms to be found in certain patents that claim inventions that are confined to specific structural forms.




There are two United States Patents that disclose structures that utilize ring or circular elements. One is the Ring Structure disclosed by U.S. Pat. No. 4,128,104 which is “a structural framework composed of ring members intersecting one another in a particular manner”. The other is the Modular Dome Structure, U.S. Pat. No. 3,959,937, which is comprised of “ring-shaped” elements of equal size which form a dome when connected in a particular manner. That disclosure is restricted to “improved building construction for domes or other spherical frames”, and does not teach a universal structural system.




Otherwise, there does not appear to be any prior art involving the structural use of toroidal elements which are designed to be load bearing.




BRIEF SUMMARY OF THE INVENTION




The present invention is a structural system which employs “toroidal elements”, structural elements which are toroidal in shape, which are connected to form structures, and a method of construction therewith. The structural system of toroidal elements may be used to create new structural forms for both stationary and moveable structures. Some of the structural forms can be applied to construct buildings for unstable foundation conditions and which can survive foundation movement and failure. The use of toroidal elements may also be applied to create structures which are dynamic, with the constituent elements capable of movement by design, not only by deflection as a result of loading, but also by the active management of structural stresses. Toroidal elements may also be varied in shape dynamically so as to achieve alteration of the shape, size and volume of the structure of which they are constituent. The use of the invention includes every conceivable structure, from the smallest to the largest, nanostructures, bridges, towers, furniture, aircraft, land and sea vehicles, appliances, instruments, buildings, spacecraft, and planetary and space habitats.




The present invention also contemplates that structures comprised of connected toroidal elements may be incorporated in yet other structures that also have conventional structural elements. The preferred embodiment of the present invention employs toroidal elements which are torsion elements or are constructions of torsion elements.




The method of construction of structures using the present invention is also disclosed through numerous drawings of combinations and arrays of connected toroidal elements.

DETAILED DESCRIPTION OF THE INVENTION




The present invention is a structural system which employs “toroidal elements”, structural elements which are toroidal in shape, which are connected to form structures, and includes a method of construction therewith. The structural system of toroidal elements may be used to create new structural forms for both stationary and moveable structures.




As used in this description and the appended claims the term “toroidal” means of or pertaining to a “toroid”. The term “toroid” is not intended to limit the present invention to employment of elements that are in the shape of a torus, which is mathematically defined as a surface, and the solid of rotation thereby bounded, obtained by rotating a circle which defines the cross section of the tube of the torus about an axis in the plane of the circular cross section. As used in this description and the appended claims the term “toroid” means any form with the general features of a torus, i.e. a tube, cylinder or prism closed on itself, without regard to any regularity thereof, and further means any tubular, cylindrical or prismatic form which is closed on itself in the general configuration of a torus, thus completing a mechanical circuit forming the “tube” of a “toroid”, regardless of the shape of the cross section thereof, which may even vary within a given “toroid”. A toroid may be formed by the connection of cylindrical or prismatic sections, straight or curved, or by the connection of straight and curved sections in any combination or order; and may be of any shape which the closed tube may form: elliptical, circular, polygonal, whether regular or irregular, symmetrical, partially symmetrical, or even asymmetrical, whether convex or concave outward, partially or completely. Moreover, as used in this description and the appended claims, the term “toroid” applies to and includes: (a) the continuous surfaces of toroids, tube walls of finite thickness, the exterior of which are bounded by the toroidal surface, and the solids that are bounded by the toroidal surface; (b) any framework of elements which if sheathed would have the shape of a toroid; (c) any framework of elements which lays in the locus of a toroidal surface; (d) a bundle or coil of fibers, wires, threads, cables, or hollow tubing that are, bound, wound, woven, twisted, glued, welded, or otherwise bonded together in such a manner as to form in their plurality or individuality a toroidal shape.




The principal objects of the present invention are:




1. To provide a universal structural system for all types of immobile and mobile structures comprised of connected toroidal elements and having a high degree of structural integrity, strength, efficiency, and flexibility.




2. To provide a structural system where toroidal elements are subjected to the greatest part of the structural loading for redistribution of such loading throughout the toroidal structures and conventional elements of the constructions in which they are included.




3. To provide a structural system in which a structure constructed of toroidal elements is uniformly loaded so that the material of which such toroidal elements are composed is uniformly stressed, thereby achieving a high strength-to-weight ratio.




4. To provide a structural system in which loads are well distributed over all of the structural elements thereof.




5. To provide a structural system which is integrated and attractive in appearance, allowing for aesthetic design with self-supporting toroidal elements in which curved structures are architecturally natural.




6. To provide a structural system with dynamic shape shifting and dynamic redistribution of loading by actuated structural connections.




7. To provide a structural system which is economical, adaptable to automated design, automated fabrication, and efficient in ultimate assembly, in its smallest elements and its largest structural forms.




8. To provide a structural system in which conventional structural elements such as beams, joists, decks, trusses, etc. can be constructed with toroidal elements.




9. To provide a structural system in which various toroidal elements may be standardized and databased with all dimensional, material and loading characteristics so as to provide for automated selection of components for structural design therewith.




10. To provide a structural system that is compatible with conventional structural systems.




Toroidal elements use the strength of materials more effectively and have the capacity to redistribute the loads distributed to them by the connections of the structural system of which they are a part, The structural system effectively distributes most compression, tension, flexion and torsion loading of constructions using the system among the connected elements. Thus the construction is distinguished from conventional constructions employing elements which function only in compression, tension or flexion, such as beams, struts, joists, decks, trusses, etc., for which torsional effects are design defects that can lead to catastrophic structural failure. However, when elements which function in compression, tension or flexion are constructed using the present invention, the same structural benefit of torsional load distribution applies.




The present invention contemplates that toroidal elements may be constructed of yet other toroidal elements, so that a given toroidal element so constructed functions to bear loads by the bearing of structural loads by its constituent substructures. Such substructures may be structural elements, toroidal, conventional or otherwise, which are part of a combination of structural elements of a scale similar to the given toroidal element; or structural elements of a scale significantly smaller than the given toroidal element and fundamentally underlying the bearing capacity of given toroidal element. In the latter case the structure of a given toroidal element may be the replication of small substructures of toroidal elements, which in turn may be replications of still smaller substructures of toroidal elements. This process of structural replication can be continued to microscopic, and even molecular, levels of smallness.




The system also includes the construction of conventional elements using toroidal elements which in turn may be used in combination with other structures using toroidal element constructions. Moreover, it is one of the features of the present system that such conventional elements, such as beams, joists, decks, trusses, etc., so constructed using toroidal elements may be engineered with arching camber. Although some toroidal elements may bear resemblance to conventional trusses, the structural integrity and strength of toroidal elements is not necessarily dependent on elements such as linear chords and struts.




Toroidal elements can be made of virtually any material suitable for the loads to which the structure may be subjected and for the environment in which the structure may be utilized.




The present invention contemplates that structures constructed of connected toroidal elements may be incorporated in yet other structures together with conventional structural elements in order to bear loads in conjunction with such toroidal structures.




The preferred embodiment of the present invention employs toroidal elements that are constructed with the use of “torsion elements” which are toroidal in shape. As used in this description and the appended claims the term “torsion element” means a structural element that functions with torsion as its principal load bearing mode. Torsion elements use the torsional strength of materials and have the capacity to bear the torsion loads distributed to them by the connections of the structural system of which they are a part. The present invention using toroidal torsion elements converts most compression, tension and flexion loading of constructions using the system to torsional loading of the torsion elements of which the constructions are comprised. The use of toroidal torsion elements also contributes to construction of toroids which are self-supporting.




Toroidal elements may be used to create new structural forms for both stationary and moveable structures. The toroidal shape allows for replication of toroidal elements to produce larger and larger toroidal elements which may be suitable to the dimensions of the structural application. A large variety of structures made feasible by origination of the replication process with toroidal elements on the order of nanostructures or larger may themselves be considered as materials which can be utilized in conventional structures such as decking, plates, skins, and sheeting of arbitrary curvature.




Erection of structural frames using the present invention requires only connection of the toroidal elements, and may use connectors which are propositioned and even integrated in the design of the toroidal elements.




The structural system is comprised of a plurality of toroidal elements connected together by a means for connection. Two or more toroidal elements may be connected in the same connection. The connection of the toroidal elements is the means by which loading is transmitted between and distributed among the toroidal elements.




As used in this disclosure and the appended claims the term “connected” means, in addition to its ordinary meaning, being in a “connection” with toroidal elements; and the term “connection” as used as in this disclosure includes, in addition to its ordinary meaning, any combination of components and processes that results in two or more structural elements being connected, and further includes the space actually occupied by such components, the objects resulting from such processes, and the parts of the structural elements connected by contact with such components or objects; but both the terms “connected” and “connection” exclude interlining (“intersection”) of structural elements as a means for connecting toroidal elements.




Toroidal elements may be connected by any means that does not permit unwanted movement in the connection, Such means may be any type of joining, such as welding, gluing, fusing, or with the use of fasteners, such as pins, screws and clamps. However, the preferred means for connection is by use of a “coupling”. The term “coupling” is used in this disclosure to mean a device which connects two or more toroidal elements by holding them in a desired position relative to one another, so that when the desired positions of the torsion elements are achieved, the toroidal elements will not be able to unwantedly move relative to each other within the coupling. The coupling may itself be constructed of toroidal elements, or may be solid or have some other structure. The term “coupling” also includes a device which connects a toroidal element to a conventional structural element by holding both the toroidal element and the conventional structural element so that when the desired position is achieved, the elements will not be able to unwantedly move relative to each other within the coupling. Although, the function of couplings is to hold toroidal elements in position in relation to each other, there may be motion of the toroidal elements associated with the structural loading of the elements, including rotation of the elements with respect to each other about the axis defined by the grip within the coupling, and sliding of the elements through the grip of the coupling. Such motion is expected and appropriate for the distribution of stress among the elements of a given toroidal structure.




The function of couplings in holding toroidal elements in position may be combined with prior positional adjustment and actuation of such adjustment. In this respect the position of toroidal elements connected by a coupling with respect to one another may be changed or adjusted and then held in the desired position. Accordingly, the coupling must be designed to have the capability for such adjustment, and may also be designed to have such adjustment actuated by some motive power. Such actuation may implement dynamic distribution of loading among the toroidal elements affected, or implement dynamic shape shifting, or both. This can be achieved by making one or more connections of the structure adjustable, with or without the use of actuation. The function of such a coupling, therefore, is to adjust the coupled connections, with or without the use of such controlled actuation, so that a toroidal element may be moved within a connection in relation to other structural elements connected therein, and then firmly held by the connection in the position resulting from such movement so that the toroidal element will not have substantial movement within the connection in relation to any other structural element in the connection unless deliberately moved again by the coupling.




The use of the invention includes every conceivable structure bridges, towers, furniture, aircraft, land and sea vehicles, appliances, instruments, buildings, domes, airships space structures and vehicles, and planetary and space habitats, The magnitude of such structures contemplated and made structurally and economically feasible by the system range from the minute to the gigantic. The structures that are possible with the use of the present invention are not limited to any particular design, and may even be freeform.




Some of the structural forms can be applied to construct buildings for unstable foundation conditions and which can survive foundation movement and failure. The use of toroidal elements may also be applied to create structures which are dynamic, with the constituent elements capable of movement by design, not only by deflection as a result of loading, but also by the active management of structural stresses. Toroidal elements may also be varied in shape dynamically so as to achieve alteration of the shape, size and volume of the structure of which they are constituent.




To present the details of the system, the function of its elements, and the method by which structures are constructed using the system, reference is made to the numerous drawings of combinations and arrays of connected toroidal elements.





FIGS. 1-4

are various views of two toroidal elements which are connected, demonstrating the fundamental operation of the present invention, the connection of toroidal elements.




Toroidal elements can be connected in closed arrays as shown in

FIGS. 5-7

, which may form the framework of larger toroidal elements. Indeed, it is contemplated by this invention that the self-similarity of toroids constructed from other toroidal elements can be extended to control the structural characteristics of such toroidal elements.




Through

FIG. 79

all of the connections between toroidal elements have been shown in the figures as “external”, i.e. achieved with an “external” coupling applied to the exterior surfaces of toroidal elements. Such connections shall continue to be referred to as “external”, as opposed to “internal” connections which include all means for connecting toroidal elements without the use of a coupling or other intermediate device. Toroidal elements in a connected combination are shown in the various views in

FIGS. 8-11

.




For the purpose of the figures of this disclosure it shall be understood that all of the closely proximate toroidal elements shown are connected in the region of their closest proximity by internal connection, unless otherwise indicated, such as by connection with couplings. Furthermore, for the purpose of the figures of this disclosure the lack of the appearance of an external coupling at the point of closest proximity of two toroidal elements shall not be taken to mean that such elements are not connectable with couplings, unless otherwise indicated. Also, all connections thus shown in the figures may be internal or external as required by the application, even though not indicated as such in a particular figure. This convention is used in the examples of closed arrays shown in

FIGS. 12-16

, where the toroidal structural modules shown in

FIGS. 8-11

form the framework of toroids.




By the convention herein established the circular array shown in

FIGS. 15 and 16

is comprised of toroidal elements that are internally connected. However, observation of an internal connection, shown in the various views of

FIGS. 17-24

between two toroids formed as shown in

FIGS. 15 and 16

, demonstrates that internal connections between toroidal elements may be achieved by the use of external connections between their constituent toroidal elements. This internal connection, rather than being accomplished by coupling of the constituent toroidal elements of the toroids, could have been accomplished by internal connections between the elements of which the constituent toroidal elements are constructed. Such internal connection may also be mediated by additional elements, toroidal or otherwise. Furthermore, this process may be continually replicated in a self-similar manner on a smaller and smaller scale, down to a fundamental toroidal element, a toroidal element which may be a construction itself, but not necessarily by formation from a circular array




Arrays of angularly connected toroidal elements that themselves form toroids may be elliptical, as shown in

FIGS. 37 and 38

, or of any other shape, and have directional characteristics as shown in

FIGS. 25-30

. Such varying constructions of toroids may be combined as needed to meet extrinsic structural requirements by tubularly coaxial connection between such toroids as shown in

FIGS. 31-33

.




Constructions from linear arrays of connected toroidal elements may also be used to form structural members such as rods, tubes, poles or posts, examples of which are shown in

FIGS. 76-79

. These constructions may also have directional characteristics similar to that of the closed arrays discussed above, and may be included in compound tabularly concentric constructions as shown in

FIGS. 80-81

.




Fundamental toroidal elements may be fabricated from what can be considered solid material, such as metal, polymers, foams, wood, or tubes of such material, as in FIG.


39


. Such, fundamental toroidal elements may even be molded as toroidal elements connected in modules, partial or whole, in the form of a framework of a toroidal element. Fabrication of fundamental toroidal elements may proceed from any standard manufacturing method, such as winding as indicated in

FIGS. 34-36

and

FIG. 40

, extrusion, injection molding, layering of resins and fabrics, and fiber compositing.




Toroidal elements may also be constructed from other toroidal elements without the use of connected arrays, such as in

FIGS. 41-49

showing toroids consisting of constituent toroids that are connected coaxially. The constituent toroidal elements of these constructions may themselves be fundamental or constructed, even from arrays of connected toroidal elements. Another example of a toroidal element constructed without the use of a circular array and which may be employed as fundamental is shown in

FIGS. 66-69

. The interlinkage, as shown in

FIGS. 70-75

, forms an apparent braid of six toroids about a central axial toroid, all of which are identical in dimension. The principal characteristic of this type of toroidal element is that the apparent braid of toroids rotates freely about its circular axis impeded only by the internal friction of the toroids and the frictional forces between them.




It is possible to construct a toroidal element with a tube defined by a closed spiral, as shown in

FIG. 50-52

, and various other spiral forms exemplified in

FIGS. 53 and 54

. The principal characteristic of this type of toroidal element is that the tubular coil rotates freely about its tubular axis, impeded only by internal friction, which is the circle within and at the center of the tube, impeded only by internal friction. Such a toroidal spiral can transmit torque about the tubular axis of the tube to any point around the tube. Such a toroidal spiral can be stabilized by another toroidal element to form a compound element as shown in FIG.


55


. Such a toroidal spiral can also be stabilized by toroidal elements connected to the periphery of the tube as shown in

FIG. 56

, so that the rotation of the spiral about its tubular axis is regulated by the peripheral toroidal elements. The toroidal spiral element may itself be a spiral array of connected toroidal elements.




Other toroids formed by closed arrays of connected toroidal elements can be stabilized and their torsion stress regulated as shown in

FIGS. 57-60

, as in the case of the toroidal element formed by a spiral, which can be seen by the comparison of

FIGS. 55 and 56

with

FIGS. 57-60

.




Virtually any shape of toroidal element is possible as shown in

FIGS. 61-65

and

FIGS. 320-325

, and may be constructed by either appropriately shaped arrays of toroidal elements, or fabricated as fundamental toroids.




The combination and orientations in which toroidal structural modules may be constructed with the use of couplings is exemplified by the categories shown in

FIGS. 82-95

. Examples of couplings that can be used to achieve such combinations and orientations are shown in

FIGS. 96-101

and

FIGS. 102-122

for two-element connections, as shown in

FIGS. 1-4

; in

FIGS. 102-107

for four-element connections, as shown in

FIGS. 92-95

; and in

FIGS. 108-119

for the types of connections shown in

FIGS. 82-87

.




The spline grip couplings and the corresponding spline collars of toroidal elements are among several other means contemplated for achieving connections between toroidal elements and couplings. Examples of such other means are welding, gluing, fusing; the use of fasteners, such as pins, screws and clamps; and the mating of the coupling with a toroidal element of non-circular cross section.




Couplings may also be designed with various mechanical devices for integrated securing against movement of the toroidal element held. An example of such a coupling is shown in

FIGS. 96-101

, a split block coupling in which each of the parts of the block


61


and


63


are fitted with spline grips


62


. The manner in which the coupling effects the connection is to close the block sections


61


,


63


around the spline collars of the toroidal elements to be connected, and bind the block with the compression band


65


tightened into the band groove


64


with a tightening device


66


, such as a ratcheted roller on which the compression band is wound.




Similarly the coupling shown in

FIGS. 102-107

is a split block coupling in which each of the parts of the block,


71


,


73


and


77


are fitted with spline grips


72


. The manner in which the coupling effects the connection is to close the block sections


71


,


73


and


77


around the spline collars of the toroidal elements to be connected, and bind the block with the compression band


75


tightened into the band groove


74


with the tightening device


76


.




The coupling shown in

FIGS. 108-119

is an open-end coupling in which each of the end caps


83


and


87


and the main body of the coupling


81


are fitted with spline grips


82


. The manner in which the coupling effects the connection is to close end caps


83


and


87


around the spline collars of the torsion elements to be connected, and bind the caps to the main body block with the compression bands


85


, which are locked to the main body by the lock pins


88


and tightened into the band grooves


84


with the tightening devices


86


.




Toroidal elements such as


102


,


104


,


106


,


108


, and


110


shown in

FIGS. 124-128

with spline collars


101


,


103


,


105


,


107


and


109


, are those which are connected by the couplings which have spline grips. The spline collars may be integral to the toroidal element, or may be attached by a means of bonding the spline collar to the toroidal elements or their components, by means of a mechanical linkage within the spline collar, or by attachment or fastening to the spline collar. If a structural element does not have spline collars attached, other forms of connection are possible, such as with a coupling with form grips, or by internal connection with toroidal elements constituting such structural elements.




An example of a split-block coupling with form grips is shown in

FIGS. 120-123

for the simplest two element connection as shown in

FIGS. 1-4

. Form grips can be a structural foam that cures to a permanent shape after being compressed about the toroidal element, or a resilient elastic cushion that grips the toroidal element. The coupling is caused to grip the toroidal element by closing the block sections


91


and


93


around the toroidal elements to be connected, so that the form blocks


92


compress and conform to the shape of the toroidal elements, moderated by the cushions


94


. The block sections of the coupling are then locked in place by either compression bands, as used on the split-block coupling shown in

FIGS. 96-101

, or other means of fastening the block together, such as screws or bolts.




Tower structures may be formed by connected stacking of prismatically or cylindrically shaped layers of connected toroidal elements, such as the cylindrical structural modules shown in

FIGS. 154-157

, or of layers with a larger number of toroidal elements, as shown in FIG.


279


. (The terms cylindrical and prismatic (or prismatical) shall be used synonymously and interchangeably hereinafter.) Such layers are level layers, and are shown in horizontal orientation throughout

FIGS. 248-281

. Also as shown in

FIGS. 248-281

such level layers of toroidal elements are arranged in closed courses. The cylindrical tower shown in

FIG. 279

is formed by such connected stacking of such level layers, each layer having the same number of toroidal elements and the same size, the toroidal elements comprising each layer having the same size, and the toroidal elements being of the same size from layer to layer. The connected stacking between adjacent layers is accomplished by the connection of each toroidal element in one layer to one corresponding toroidal element in each adjacent layer. The tower structure thus formed is such that each toroidal element in all but the top and bottom layers can be connected in the structure by a “four point connection”, which is a connection at four points on a toroidal element to the adjacent toroidal elements: connection to each of the adjacent toroidal elements above and below, and connection to each of the toroidal elements laterally adjacent within the layer.




Tower structures may also be formed by connected stacking of pyramidally (used in the sense of pertaining to the frustum of a pyramid) shaped layers of connected toroidal elements. The tower structure shown in

FIGS. 248-251

is formed by connected stacking of pyramidally shaped layers of connected toroidal elements that are pyramidal structural modules as shown in

FIGS. 152-153

, which are comprised of six toroidal elements arranged in the planes of the surfaces of the frustum of a pyramid. The pyramidal structural modules in such a vertical array may be of upwardly diminishing size, as shown in

FIGS. 248-250

, so that the size and shape of the base of each of the pyramidal layers is the same as the size and shape of the top of the next lower layer upon which it is stacked. The connected stacking between adjacent layers is accomplished by the connection of each toroidal element in one layer to one corresponding toroidal element in each adjacent layer, so that each toroidal element can be connected in the structure by a “four point connection”. Such pyramidally shaped layers may have a large number of elements so as to approximate a conical (used in the sense of pertaining to the frustum of a cone) shape, which may form a conical tower structure with connected stacking, such as shown in FIG.


277


. (The terms conical and pyramidal shall be used synonymously and interchangeably hereinafter.) In the conical tower shown in

FIG. 277

the size of each conically shaped layer of connected toroidal elements is smaller than the next lower layer, i.e. upwardly diminishing in size, but the solid angle of the conical shape is the same; the size of all the toroidal elements in any one layer is the same, but is smaller than the size of the toroidal elements in the next lower layer; and the number of toroidal elements in each of the layer is the same from layer to layer. For conical towers, the fact of upwardly diminishing in size may be stated in a way similar to that for towers of pyramidal layers: the size and shape of the base of each of the conically shaped layers is the same as the size and shape of the top of the next lower layer upon which it is stacked. Again, the connected stacking between adjacent layers is accomplished by the connection of each toroidal element in one layer to one corresponding toroidal element in each adjacent layer, so that each toroidal element can be connected in the structure by a “four point connection”.




Domical structures may also be formed, as shown in

FIG. 252

, by connected stacking of level conically shaped layers of connected toroidal elements, such layers being also upwardly diminishing in size, as indicated with the conical tower shown in

FIG. 277

, but with an increasing solid (polar) angle of the conical shape. Also as in the case of the conical tower, the size of all the toroidal elements in any one layer is the same, but is smaller than the size of the toroidal elements in the next lower layer; and that the number of toroidal elements comprising each of the layers is the same from layer to layer; so that the toroidal elements in said any one layer will lie in the same domical surface as the next lower layer. Again, the connected stacking between adjacent layers is accomplished by the connection of each toroidal element in one layer to one corresponding toroidal element in each adjacent layer, so that each toroidal element can be connected in the structure by a “four point connection”.




Spherical structures such as those shown in

FIGS. 253-254

may be formed by connection of the base layers of two of the domical structures shown in

FIG. 252

, which are in opposite polar orientation (in a convexly opposite relationship), where the bases are of the same size and shape. Where the base layers of the domical structures have the same number of elements, such connection of the base layers may be accomplished by the connection of each toroidal element in the base layer of one domical structure to one corresponding toroidal element in the base layer of the other domical structure, so that each toroidal element in both base layers can be connected in the spherical structure by a “four point connection”.




Intermediate latitudinal toroidal elements may also be used between any adjacent layers of connected toroidal elements in a domical structure, in a spherical structure, in a conical/pyramidal tower structure, and in a cylindrical/prismatic tower structure. Such intermediate latitudinal toroidal elements may also be used to effect a second kind of connected stacking, such as where the number of connected toroidal elements comprising the layers to be connected are not the same, by connecting the toroidal elements of each layer to the intermediate latitudinal toroidal element. Such connected stacking permits the use of layers with different numbers of connected toroidal elements in cylindrical tower structures, conical tower structures and domical structures. In the case of domical structures, connected stacking with intermediate latitudinal toroidal elements, as shown in

FIGS. 275-276

, is used where the toroidal elements are approximately the same size from layer to layer, but with upwardly diminishing numbers of toroidal elements in each layer: the toroidal elements comprising each layer are connected to other layers via intermediate latitudinal elements between the layers. Such connected stacking could also be used to connect two domical structures to form a spherical structure where the numbers of toroidal elements in the base layers of each of the domical structures are not the same: connection of the base layers of the domical structures may be made via an intermediate latitudinal toroidal element which is equatorial to the sphere to be formed.




Structures formed of level layers of connected toroidal elements, such as domical and spherical structures, can also be reinforced longitudinally, as in

FIGS. 257-258

, which show a spherical structure as shown in

FIGS. 255-256

with the toroidal elements connected to the left and right via intermediate longitudinal toroidal elements, where the number of connected toroidal elements is the same from layer to layer.




Layered domical and spherical structures may also be prolate, as shown in

FIGS. 259-260

, or oblate, as shown in

FIGS. 261-262

; and may even be prolate along one horizontal axis and oblate along the other perpendicular horizontal axis, as shown in

FIGS. 263-267

.




A third kind of connected stacking of conically shaped layers having the same number of connected toroidal elements may be used to form domical structures, as shown in

FIGS. 268-269

, wherein adjacent layers are interleaved so that each toroidal element in one layer is connected to the two toroidal elements in each adjacent layer with which it is interleaved. (The term “interleaved” is used here although it may be more accurate to use the mathematical term “packed on the surface of the dome”, as in the mathematical theory of packing.) As in the case of the domical structure shown in

FIG. 252

, the toroidal elements in each layer is of upwardly diminishing size, but with an increasing angle of the conical shape. Also as in the case of the domical structure shown in

FIG. 252

, the size of all the toroidal elements in any one layer is the same, but is smaller than the size of the toroidal elements in the next lower layer; and the number of toroidal elements comprising each of the layers is the same from layer to layer, so that the toroidal elements in said any one layer will lie in the same domical surface as the next lower layer. The connected stacking between adjacent interleaved layers is accomplished by the connection of each toroidal element in one layer to the two toroidal elements in each adjacent layer which it is interleaved, so that each toroidal element can be connected in the structure by a “six point connection”, which is a connection at six points on a toroidal element to the adjacent toroidal elements: connection to each of the adjacent toroidal elements, two above and two below, and connection to each of the toroidal elements laterally adjacent within the layer. The domical structure thus formed is such that each toroidal element in all but the top and bottom layers can be connected at six points to adjacent toroidal elements. Such interleaved domical structures may also be connected at their bases in an opposite polar orientation (in a convexly opposite relationship), where their respective bases are of the same size and shape, to form a spherical structure as shown in FIG.


270


. Where the base layers of the domical structures have the same number of elements, such connection of the base layers can be accomplished by the connection of each toroidal element in the base layer of one domical structure to two toroidal elements with which it is interleaved with the base layer of the other domical structure, so that each toroidal element in both base layers can be connected in the structure by a “six point connection”. As with the other domical and spherical structures shown in

FIGS. 259-262

, domical and spherical structures with interleaved layers may also be prolate, as shown in

FIG. 271

, or oblate, as shown in

FIG. 272

; or prolate along one horizontal axis and prolate along the other perpendicular horizontal axis.




Tower structures may also be formed by connected stacking of interleaved layers of connected toroidal elements, as shown in

FIG. 278

for conical, and

FIG. 280

cylindrical. As in the case of the domical structures connected stacking between adjacent layers is accomplished by the connection of each toroidal element in one layer to the two toroidal elements in each adjacent layer which it is interleaved, so that each toroidal element can be connected in the structure by a “six point connection”.




Spherical structures may also be formed by arranging toroidal elements in the planes of the surfaces of an imaginary polyhedra, so that the toroidal elements are connected where they are nearly tangent to one another near the mid points of the edges of a polyhedra. Such spherical structures may be exemplified with regular polyhedra such as the icosahedron and the dodecahedron. The spherical/icosahedral structure shown in

FIGS. 239-241

is comprised of twelve connected toroidal elements, each of which is arranged in the plane of one of the surfaces of an imaginary regular icosohedron. The resulting spherical structure is such that each of the toroidal elements lies on the surface of the spherical structure. The spherical/dodecahedral structure shown in

FIGS. 242-244

is comprised of twenty connected toroidal elements, each of which is arranged in the plane of one of the surfaces of an imaginary regular dodecahedron. The resulting spherical structure is such that each of the toroidal elements lies on the surface of the spherical structure. The gaps in the resulting spherical structures may be bridged by additional smaller toroidal elements, as shown in

FIGS. 245-247

, in which gaps in the spherical structure shown in

FIGS. 242-244

have been bridged, so that each of the bridging toroidal elements also lies on the surface of the structure.




The formation of a virtually unlimited number of structures are possible with the combination of the basic structures shown here as examples. One example of such a combination is shown in

FIG. 281

, which is a schematic elevation of a tower structure comprised of a conical base of the same type as the conical structure shown in

FIG. 278

, with interleaved connection to a section of cylindrical tower structure as shown in

FIG. 280

, topped by an interleaved connection to a trunkated section of a prolate spherical structure as shown in FIG.


259


.




The formation of structures using the system proceeds from constructions which may be referred to as “structural modules”. One basic form of structural module is a connected triangular array of toroidal elements shown in

FIGS. 129 and 130

. Two types of connected linear arrays of the triangular structural module are shown in

FIGS. 131-136

which form two different types of rod, beam, or post structures having different structural properties. Connected arrays of such modules can/form plate or deck structures as shown in

FIGS. 137 and 138

. Another basic structural module is the connected cubic array of toroidal elements which is shown in

FIGS. 139 and 140

, with a connected linear array shown in

FIGS. 141 and 142

forming rod, beam or post structures. Connected arrays of these modules can form plate, deck and joist structures as shown in

FIGS. 143-145

. As can be seen from some of the examples of possible structural modules in

FIGS. 146-157

, a wide variation thereof is possible.





FIGS. 158-164

are examples of the more complex structures, such as arches or ribbing, formed when the structural modules shown are connected in arrays, as with the structural module shown in FIG.


156


. The closed array in

FIG. 158

may also be another form of toroidal element.




Structures may also be formed from polygonal toroidal elements, such as that shown in

FIGS. 165 and 166

. The preferred use of such forms is as a body for a complex toroidal element having internal shafts for the absorption of torsion stress as shown in FIGS


167


and


168


, with a reinforced version being shown in

FIGS. 169 and 170

. One variation of this type of toroidal element is shown in

FIGS. 171-173

, in which torsion stress is absorbed by multiple internal shafts


112


. The shafts


112


are the point region of connection with other elements where they are not enclosed by the polygonal body


111


of the element. The shafts


112


rotate on bearings


114


which are positioned by bearing mounts


113


which are fixedly attached to the body


111


. A torque applied to turn the shaft


112


at its point of connection will induce a stress in the shaft


112


if the rotation of the shaft is restricted in some way. In the element shown the shaft


112


to which the torque applied is connected at both ends to other shafts


112


by means of a universal joint


115


which transmits the torque to the other shafts


112


. If the rotational motion of any of the shafts


112


are restricted, a torque on the shaft


112


will induce a torsional stress in the shaft


112


, and the loading will be transmitted to adjacent shafts


112


by means of the universal joint


115


which connects them. Restriction of motion of a shaft


112


can be provided for by a rotation block


116


, which is a means of fixing the end of a shaft


112


to the body


111


or of otherwise resisting rotation so that the end of the shaft


112


will not rotate freely Such a rotation block


116


may be applied to the ends of a shaft


112


to which the torque may be applied where it is exposed for connection to other torsion elements as in

FIGS. 174 and 175

, or to additional shafts


112


as previously discussed, also shown in

FIGS. 176 and 177

. If there are no rotational blocks the shafts will be free to rotate. If such free shafts are further connected by universal joints around the sides of the element, as shown in

FIGS. 178 and 179

, the torque will transmitted from the region of application to the other region of connection. Thus rotation induced at one side of the element will be transmitted to the other side of the element without substantial constraint within the element. However, if the movement of the shafts on one side of the element are restricted, as by connection to another torsion element, a torsional load will result and transmitted equally along the connected shafts and torsion stress will be induced therein.




As with other toroidal elements, polygonal toroidal elements may be connected in arrays, which may be closed to form a toroid as shown in

FIGS. 180-185

and


192


. The couplings used may be of the split block type shown in

FIGS. 186-191

. Thus polygonal toroidal elements are another means for implementing the invention. Also as with other toroidal elements a wide variation in form and combination is possible with polygonal toroidal elements, as shown in

FIGS. 193-204

) in which polygonal elements are shown that range from the pentagonal (

FIGS. 193-196

) to the octagonal (

FIGS. 197-200

) to the nonogonal (

FIGS. 201-204

) and with the number of sides limited only by the application.

FIGS. 205-208

demonstrate the manner in which polygonal toroidal elements may be combined with other toroidal elements to form complex toroidal elements with structural features that can be tailored to any structural application. In this last case it should be noted that the toroidal shell enclosing the polygon is partially filled interior to the polygonal toroidal element. Such filling can be with the material of the shell, structural foam or other structures, partially or not at all, again, depending on the structural requirements of the By application.




In addition to the connections between toroidal elements in which the toroidal elements remain outside of the peripheral tube of the other, previously demonstrated in

FIGS. 1-4

,


8


-


11


, and


82


-


95


, connections between toroidal elements where one element is within the space surrounded by the tube of another are a useful structural alternative to combination by constructing toroidal element& with coaxial tubes. Such a variation is shown in

FIGS. 209-218

where the toroidal elements are coaxial, and in

FIGS. 219-238

where the axes of the toroidal elements are angulated with each other.




Certain basic structural forms that are difficult to achieve without significant structural disadvantage using conventional structural systems, are natural using the present invention with no structural disadvantages. Among these are symmetrical spherical frameworks, as shown in

FIGS. 239-247

, and framework towers, as shown in

FIGS. 248-251

. Other examples of structures for which toroidal elements are similarly suitable are shown in

FIGS. 252-281

. All of the simple structural forms demonstrated in

FIGS. 239-281

are also useful in combination with each other, for reinforcement and for aesthetics, as well as in the design of complex structures.




With regard to the spherical frameworks shown in

FIGS. 239-247

another useful structural form is possible with the replication of a section as shown in

FIGS. 314-316

, and then connecting it in an appropriate scale to a toroidal element forming the spherical surface shown in

FIGS. 317-319

. The replication of the spherical section shown in

FIG. 314

is applied once


141


and then again in smaller scale


142


to the first. This application of the spherical section shown in

FIG. 314

can be made in replication to all of the toroidal elements that form the sphere, and yet again and again to all of the toroidal elements that form successive replications, until a practical limit is reached beyond which the process has no structural efficacy.




Generally, structures such as buildings, bridges, even automobiles, seacraft, airframes and spaceframes are considered to be static structures in accordance with their manner of performance. That is, the expectation of performance for such structures is that they respond to the loads to which they are subjected by adequate management of the stress on the materials used and the means by which the materials are connected to comprise the structure. There are some structures that are built with moving parts, such as a roof that opens by sliding or some other aperture that is created by actuation, manual or otherwise, as in the housing of an astronomical observatory. As stated earlier the present invention also contemplates its application to create a dynamic structure, a structure in which the stress of the materials and their connections are managed by automated actuation of the coupling of toroidal elements. Also as stated earlier, this invention contemplates the shifting of the size and shape of structures by actuation of couplings.




An example of an actuated coupling which can perform a fundamental shifting of shape is shown in

FIGS. 282-284

, in which a motor


135


rotates a bearing


133


supporting spline grip


132


by the rotational power it delivers to the drive


136


through the use of a transmission


134


. When the motor


135


is powered, the spline grips


132


are driven, in a controlled manner to rotate and thus rotate a toroidal element held in a grip, in relation to the body


131


of the coupling, as well as any other torsion or toroidal element held in the other spline grip


132


. The manner in which the change in shape of a 20 element array can be effected using such actuated couplings is demonstrated in

FIGS. 285-287

. Couplings such as those described above and shown in FIGS.


282


-


284


(but not shown in

FIGS. 285-287

) would connect the toroidal elements, in the region of closest proximity of the elements, and would cause the angulation of the elements to change with sufficient precision so as to achieve the exact shape and size of the resulting toroid required. Such a change of shape or size could be directed to take place in an organized way for all of the toroidal elements of the structure, including replicated substructures which would result in a change of shape or size of the entire structure. An example of such an operation is shown in the schematic series of

FIGS. 288-297

, where the frame of the surface of the prolate spheroid (

FIG. 288

) is transformed in stages (

FIGS. 289 and 290

) to the frame of the surface of a sphere (

FIG. 292

) by the changing of the shape of the constituent connected elliptical toroidal elements comprising the frame of the surface of the prolate sphere to more circular toroidal elements. This transformation results in a reduction of the volume bounded by the framework. A further transformation is shown in the schematic series of

FIGS. 293-297

where the frame of surface of the sphere (

FIGS. 292 and 293

) is transformed in stages (

FIGS. 294-296

) to the frame of the surface of an oblate spheroid (

FIG. 297

) again by the changing of the shape of the constituent connected circular toroidal elements comprising the frame of the surface of the sphere to elliptical toroidal elements. This transformation results in an increase in the volume bounded by the framework. A similar but isovolumetric pair of transformations is shown in the series of

FIGS. 298-307

.




This aspect of the present invention thus demonstrated for spheroids is a general property of the structural system. This can be demonstrated further, schematically, with the transformation of a plane array of connected toroidal elements, schematically shown in three views in

FIGS. 308-310

, to a connected array of toroidal elements in the surface of a paraboloid, also schematically shown in three views in

FIGS. 311-313

, by a calculated and controlled changing of the shape of the constituent connected toroidal elements comprising the framework of the plane to more elliptical toroidal elements variably to form the framework of the paraboloid. Such shape shifting may be used to alter the shape or size of any array of elements, not only those that provide the framework of surfaces.




While the invention has been disclosed in connection with a preferred embodiment, it will be understood that there is no intention to limit the invention to the particular embodiment shown, but it is intended to cover the various alternative and equivalent constructions included within the spirit and scope of the appended claims.
