    EXAMPLES OF THE DISCLOSED TECHNOLOGY

    [0047] FIG. 1 is a perspective view of a top 100 (which is also referred to as a furniture top and/or a table top) having a radial topology, according to one example. The top 100 (and/or any top or structure described herein) can be a portion of a piece of furniture configured to form a flat surface. For example, the top 100 (and/or any top or structure described herein) can be coupled to a base portion (e.g., one or more legs) to form a table. However, it should be understood that the top 100 can be used to form any piece of furniture (for example, a counter, a shelf, a desk, a stool) or furniture accessory (for example, a picture frame, a place mat, a coaster, a mousepad, etc.) that defines a flat surface.

    [0048] As shown, the top 100 can comprise rigid modules 101, 102, 103, 104, and 105 (which are also referred to herein as modular units, table top portions, epicyclic units, leaves, furniture leaves, and/or table leaves). However, as discussed below with respect to other examples, the top 100 can include any number of modules. Each module 101, 102, 103, 104, and 105 can be equal in size, shape, and thickness. Modules 101, 102, 103, 104, and 105 can be connected by interlocked knockdown joints 111, 112, 113, 114, and 115 (which are also referred to herein as joints, imbricated joints, tessellated joints, and/or half-lap joints). Although specific reference is made to half-lap joints throughout the present disclosure, any suitable joint can be used to connect the modules. Each module 101, 102, 103, 104, and 105 can be slidably joined or connected to two adjacent modules, e.g., module 101 can connect with module 102 at half-lap joint 111, and with module 105 at half-lap joint 115. Each module 101, 102, 103, 104, and 105 can be connected to define a planar top surface 100A of the top 100. A central void or oculus 550 can be present in this example, wherein the top 100 conforms to a pentagonal topology by the alignment of the five modules 101, 102, 103, 104, and 105.

    [0049] FIG. 2 is an exploded perspective view of the top 100 of FIG. 1 showing modules 101, 102, 103, 104, and 105 separated from each other. Each module 101, 102, 103, 104, and 105 can comprise a top tongue portion 101A, 102A, 103A, 104A, and 105A (which is also referred to herein as an upper lobe), respectively, and a bottom tongue portion 101B, 102B, 103B, 104B, and 105B (which is also referred to herein as a bottom lobe), respectively. Each lobe can include a convex surface 202 (which is also referred to herein as a convex portion) that can slidably connect to or mate with a corresponding concave surface 203 (which is also referred to herein as a concave portion) of an adjacent lobe along plane lines. Each top and bottom lobe can also comprise a centered pivot 200 (FIG. 4) to pivotably or rotatably connect and align each module into an epicyclic unit that can define an axial rotation between lobes in a turret-like fashion. As such, each module 101, 102, 103, 104, and 105 can be slidably connected to two adjacent units to form a rigid, tessellated structure (i.e., the top 100). Mechanical and/or magnetic fasteners can be employed to add stability to each joined top and bottom lobe on each module as appropriate.

    [0050] FIG. 4 is an exploded perspective top view of two modules 101 and 102 showing upper lobes 101A and 102A and lower lobes 101B and 102B. Each module 101 and 102 includes two lobes. For example, module 101 includes the upper lobe 101A and the lower lobe 101B. Similarly, module 102 includes the upper lobe 102A and the lower lobe 102B. Each lobe 101A, 101B, 102A, and 102B can comprise an identical crescent-shaped or lune-shaped structure of appropriate material, size, thickness, and radius or diameter. Each lobe 101A, 101B, 102A, and 102B can include a convex surface 202 and a concave surface 203. As shown, the convex surface 202 and the concave surface 203 have the same radius of curvature. Each lobe 101A, 101B, 102A, and 102B can have an upper surface 204 and a lower surface 205. In some examples, the upper surface 204 and the lower surface 205 of each lobe 101A, 101B, 102A, and 102B can be flat or planar. A void or hole 201 can be drilled at the center of the arc (which is also referred to herein as a convex arc) defining the convex surface 202, and a pin or pivot 200 (which is also referred to herein as an indexing pin) can be employed to allow for epicyclic rotation between each upper and lower lobe.

    [0051] As shown in FIG. 3, three surfaces of the module 101 can contact three corresponding surfaces of the adjacent module 102 to form the half-lap joint connecting modules 101 and 102. The concave surface 203 of the upper lobe 101A can be tightly fit or fayed to the convex surface 202 of the upper lobe 102A to form a first shoulder portion 111A (which is also referred to herein as an upper shoulder portion and/or a top shoulder portion) of the half-lap joint 111. The concave surface 203 of the lower lobe 102B can be fayed to the convex surface 202 of the lower lobe 101B to form a second shoulder portion 111B (which is also referred to herein as a lower shoulder portion and/or a bottom shoulder portion) of the half-lap joint 111. The upper surface 204 of the lower lobe 102B can be fayed to the lower surface 205 of the upper lobe 101A to form a cheek portion (which is also referred to herein as a middle portion and/or an intermediate portion) of the half-lap joint 111. In this example, no permanent bonding between modules is employed, beneficially allowing for moving, assembly, and disassembly as desired with minimal, if any, tooling. An oculus 550 can be formed according to the juxtaposition between the size of each concave and convex surface on each lobe. Any number of additional modules can be then added to form a closed, tessellated loop of modules, which beneficially provides for a modular table surface.

    [0052] FIG. 5 is a perspective top view of a furniture top 300 comprising three modules 101, 102, and 103, according to one example. The three modules 101, 102, and 103 can be aligned and configured such that the top 300 has a triangular topology. Each top lobe 101A, 102A, and 103A can be fayed together at the upper shoulder portions 111A, 112A, and 113A of half-lap joints 111, 112, and 113, respectively. Each bottom lobe 101B, 102B, and 103B can be fayed together in a reversed manner, for example, at bottom shoulder portions 111B and 112B of joints 111 and 112, to form a reverse spiral or spica between all top and bottom lobes forming the structure. A triangular oculus 350 is a consequence of the radial geometry used in this example and is defined by a portion of the cutout on each lobe.

    [0053] FIG. 6 is a perspective top view of a furniture top 400 comprising four modules 101, 102, 103, and 104 configured to define a top with quadrangular radial topology, according to an example. Module 101 can be slidably connected to module 104 at tessellated joint 114, and can be slidably connected to module 102 at tessellated joint 111. Module 103 can then be slidably connected to module 102 at tessellated joint 112, and can be slidably connected to module 104 at tessellated joint 113. In this example, an oculus 450 having quadrangular topology is defined by a segment of each cutout edge of each module.

    [0054] FIG. 7 is a perspective top view of a furniture top 500 comprising six modules 101, 102, 103, 104, 105, and 106 configured to form a top with hexagonal radial topology. Module 101 can be fayed or tessellated to module 106, and to module 102, at joints 116 and 111, respectively. Module 103 can be fayed to modules 102 and 104 at joints 112 and 113, respectively. Module 105 can then be fayed or imbricated to modules 104 and 106 at joints 114 and 115, respectively. In this example, an oculus 650 having hexagonal topology is resultant, and is formed by a convergence of a segment of each convex lobe at the center of the structure.

    [0055] FIG. 8 is a perspective top section view of a furniture top 600 composed of eight modules 801, 802, 803, 804, 805, 806, 807, and 808 configured to define a top conforming to an oval or elliptical topology. In this example, different modules 801, 802, 803, 804, 805, 806, 807, and 808 can have different relative angles between the top and bottom lobes, such that the top 600 is radially asymmetric. Module 801 can be fayed to module 802 at joint 811, and fayed to module 808 at joint 818. Module 805 can be fayed to module 806 at joint 815, and to module 804 at joint 814. Module 803 can be fayed to module 802 at joint 812, and to module 804 at joint 813. Module 807 can be fayed to module 806 at joint 816, and with module 808 at joint 817. As shown, the top conforms to an oval or elliptical topology. An oculus 850 is defined by the juxtaposition of each module in the structure.

    [0056] FIG. 9 is a perspective top front view of the top 600 of FIG. 8 showing modular units 801, 802, 803, 804, 805, 806, 807, and 808 configured to define a top with oval or elliptical topology. Module 803 can be slidably connected to module 802 at joint 812, and with module 804 at joint 813. Module 807 can be slidably connected to module 806 at joint 816, and with module 808 at joint 817. Module 801 can be slidably connected with module 802 at joint 811, and can be slidably connected to module 808 at joint 818. Module 805 can then be slidably connected to modules 804 and 806 at joints 814 and 815 respectively, forming a closed plane structure. In this example, the oculus 850 can be expanded by employing slight modifications to the relative angles between cutouts on some or all of the modules in use, thereby changing the topology of the structure, i.e., the modules can be reconfigured to define a top exhibiting octagonal radial topology.

    Operation

    [0057] In operation, one aligns each module axially conforming to the radial geometry required to form a closed loop of modules wherein each module is connected to two adjacent modules. Each individual module can be indexed to its appropriate radial juxtaposition by using visual, magnetic, and/or mechanical alignment mechanisms. For example, referring back to the example illustrated in FIG. 1, a top 100 with pentagonal topology can be constructed from five individual modules indexed such that the correlation between each top and bottom lobe is configured to achieve a slidable, tessellated connection defined according to radial pentagonal geometry. A first module 101 can be placed top face down onto a stable horizontal surface. A second module 102 can then be aligned top face down to slidably connect to module 101 along the fayed and sculpted joint 111. Magnetic or mechanical fasteners can then be used to add stability to the joint 111 by connecting the bottom lobe 101B of the first module 101 to the top lobe 102A of the second module 102. Modules can be further added sequentially, slidably connecting module 103 to module 102, module 104 to module 103, and module 105 to modules 104 and 101, forming a rigid, closed ring-like structure conforming to pentagonal topology. The joined top can then be turned over to expose the top surface and can then be attached to a suitable supporting base (for example, one or more legs) to form a table or other piece of furniture.

    [0058] The top can be changed in size and shape by the addition of one or more modular units. As an example, a pentagonal top can be disassembled by reversing the assembly instructions, then re-indexing the necessary modules axially into a hexagonal or an octagonal configuration for reassembly into a top surface with a larger surface area. In this way, the top can be beneficially enlarged or reduced in a modular fashion with a minimal use of tooling.

    [0059] The top can also be decreased in size and shape by removing one or more modular units. As an example, a pentagonal top can be disassembled, re-indexed, and reassembled into a structure conforming to quadrille or triangular topology as needed.

    [0060] Modules can be further aligned to form an unlimited number of surface shapes and sizes. As an example, a top can be defined to form an organic shape provided that each module is configured to join two adjacent modules. In another example, an oculus could be configured to define an area enabling a surface to extend around a tree or fountain.

    [0061] In another example, a top conforming to hexagonal topology can be disassembled, re-indexed, and reconfigured into two separate tops, each conforming to triangular topology. Configurations and reconfigurations are limited by only the number of available modular units

    [0062] Modules are sizable, allowing for changes in purpose and use by alteration of physical dimensions, materials, fastener type, or geometric topology while maintaining epicyclic symmetry. Tops can be configured into modular groups along horizontal planes as a means to provide a rigid surface larger than the capacity of a single table structure.

    [0063] In view of the many possible embodiments to which the principles of the disclosed invention may be applied, it should be recognized that the illustrated embodiments are only preferred examples of the invention and should not be taken as limiting the scope of the invention. Rather, the scope of the invention is defined by the following claims. We therefore claim as our invention all that comes within the scope and spirit of these claims.
