DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0051] The following disclosure is presented to provide an illustration of the general principles of the present invention and is not meant to limit, in any way, the inventive concepts contained herein. Moreover, the particular features described in this section can be used in combination with the other described features in each of the multitude of possible permutations and combinations contained herein.

[0052] All terms defined herein should be afforded their broadest possible interpretation, including any implied meanings as dictated by a reading of the specification as well as any words that a person having skill in the art and/or a dictionary, treatise, or similar authority would assign thereto.

[0053] Further, it should be noted that, as recited herein, the singular forms “a”, “an”, “the”, and “one” include the plural referents unless otherwise stated. Additionally, the terms “comprises” and “comprising” when used herein specify that certain features are present in that embodiment; however, this phrase should not be interpreted to preclude the presence or addition of additional steps, operations, features, components, and/or groups thereof.

[0054] All examples and conditional language recited herein are intended for pedagogical purposes to aid the reader in understanding the principles of the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, i.e., any elements developed that perform the same function, regardless of structure.

[0055] Reference will now be made to several embodiments of the present invention(s), examples of which are illustrated in the accompanying figures. Wherever practicable, similar or like reference numbers may be used in the figures and may indicate similar or like functionality. The figures depict embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.

[0056] Toy building kits are generally most valuable for the user when they enable him or her the largest breadth of possible building options. This can be assessed both in terms of the kit offering more possible interactions of parts or, more broadly, in terms of the kit enabling a larger variety of constructed structures. The present invention is a refinement towards that end. Possible model forts which can be built are shown conceptually FIG. 1. The flags and/or panel pieces can be coupled to individual connector hubs or poles in the same way that the connector hub pieces are coupled to other individual pieces as described below, or they can be attachable via other, independent mechanisms, such as the clip 610 depicted in FIGS. 33-35, which has levers 612 adapted to widen a mouth 614 of clip 610 when pushed towards each other. Clip 610 can, for example clip onto a pole connector 8. In any event, these ornamental pieces do not alter the functionality of the remainder of the kit components.

[0057] As can be seen in FIGS. 1-3, the majority of a completed structure is defined by a series of pole-shaped connectors 8 (see FIGS. 4-9). These poles 8 define a shape (e.g., a facsimile of a building) by connecting to one another via connector hub pieces. These hubs can be used to line up two poles in the same direction (i.e., collinearly), or the hubs can act as joints to position two poles at angles (e.g., perpendicularly) with respect to one another.

[0058] The kit components described herein can be made of plastic or any other suitable material. In certain embodiments, the components can be manufactured via an injection molding process.

[0059] In a preferred embodiment, the pole connectors are rigid; however, in some embodiments, they may be flexible. On the most basic level, the poles interact with connector hub pieces by being received in one or more ports on the hub. In some embodiments, for better compatibility with the ports, the ends of the poles may have associated retention devices (not shown), such as a structure at the end of the poles, to facilitate a more secure fit with the ports. These retention devices can be magnetically-based (e.g., in cooperation with magnets in the hubs), use male-to female connectors/threads, or otherwise mechanically secure the pole connectors to the connector hub pieces. In certain embodiments, the retention devices can be selectively removed by the user. In some embodiments, no retention device is used, and a compression and/or friction fit is relied upon. To this end, poles with larger diameters can enhance the fit between the ports and the pole connectors. To increase building versatility, poles of various sizes and/or lengths can be included in a single kit (see especially FIGS. 36 and 37). For aesthetic reasons, or to inhibit entry of foreign substances into the hollow diameter of pole connector 8, an internal shape 5 extending through the length of the pole connector 8 could take up space in the otherwise hollow pole. This internal shape 5 can for instance, be an “X” shape or a “Y” shape and formed by extrusion of material during the manufacturing process of pole connector 8.

[0060] FIG. 10 shows a schematic of a kit component. Specifically, it is a multi-sided five-point connector hub 10 with five lateral ports 12 spaced around the circumference of a cylindrical base 14. The base 14 itself has a pair of opposing ports 16, 18 on opposing ends of base 14. Like the lateral ports 12, the opposing ports 16, 18 operate to receive pole connectors. In one embodiment, each opposing port 16, 18 has a dead-end configuration, wherein there is no interconnection between ports 16, 18. In alternate embodiments, a lumen 20 is defined therebetween. In some embodiments, lumen 20 can enable a pole connector (not shown) to pass therethrough, with or without resistance. In another embodiment, one or more of opposing ports 16, 18 has a stop 22, which serves to allow ports 16, 18 to receive a pole connector without allowing the pole to pass completely through lumen 20. In this manner, two pole connectors can be received, one in each of ports 16, 18 without any mutual interference. For an improved friction fit, fingers 50 can be provided on the inner walls of ports 12, 16, 18.

[0061] FIGS. 16-18 show a representation of a second kit component, a six-point connector hub 110, which operates similarly to five-point hub 10. Specifically, six-point hub 110 is multi-sided and has six lateral ports 112 spaced around the circumference of a cylindrical base 114. The base 114 itself has a pair of opposing ports 116, 118 on opposing ends of base 114. Like the lateral ports 112, the opposing ports 116, 118 operate to receive pole connectors. In one embodiment, each opposing port 116, 118 has a dead-end configuration, wherein there is no interconnection between ports 116, 118. In alternate embodiments, a lumen 120 is defined therebetween. In some embodiments, lumen 120 can enable a pole connector (not shown) to pass therethrough, with or without resistance. In another embodiment, one or more of opposing ports 116, 118 has a stop 122, which enables ports 116, 118 to receive a pole connector without allowing it to pass through lumen 120. In this manner, two pole connectors can be received, one in each of ports 116, 118 without any mutual interference. For an improved friction fit, fingers 150 can be provided on the inner walls of ports 112, 116, 118. Another possibility to improve a friction fit would be to provide slits (not shown) in the walls of ports 116, 118, or on the various other ports of the present invention.

[0062] In an embodiment, both connectors 10 and 110 can be made of a flexible material (see FIGS. 11, 13 and 15). In an embodiment, connectors 10, 110 are manufactured via an injection molding process. When made to be flexible, lateral ports 12, 112 can be elastically moved into positions different from their default orientations. Two or more lateral ports 12, 112 can be moved in the same direction; alternatively, some of ports 12, 112 can be moved in different (i.e., opposite) directions. In such instances, any lateral ports 12, 112 positioned in this fashion will flex back to their default position when the forces on them are released. However, when the lateral ports 12, 112 are connected to a pole connector that is fixed in position (e.g., one that is part of a constructed structure), tension forces will function to maintain lateral ports 12, 112 in their alternate positions. To this end, hubs 10, 110 can operate as unique joint connectors (e.g., corner connectors) that can place pole connectors in additional orientations/angles than those described elsewhere herein. In an embodiment, flexible hubs 10, 110 can be adapted to better comply with the lateral ports 12, 112 in flexed position. To this end, a plurality of dimples 24, 124 can be placed around opposing ports 16, 116, 18, 118. These dimples 24, 124 serve as a stop to flexed ports 12, 112 and add to the versatility of hubs 10, 110. In an embodiment, the dimples 24, 124 can be substituted for triangular tabs (not shown) that perform the same function as dimples 24, 124 (i.e., as a stop) or can complement them.

[0063] To improve the ease of connecting and disconnecting poles 8 to hubs 10, 110 ribbing 26, 126 can be added to the outer circumference of lateral ports 12, 112 to facilitate the gripping of ports 12, 112. To enable ease of use, ports 12, 112 can also have a lip 28, 128 with a diameter greater than the inner diameter of ports 12, 112. This adaption facilitates separation of connector poles from hubs 10, 110.

[0064] In further embodiments of the present invention, additional connectors are provided as part of a kit. FIGS. 19-22 show an eight-sided connector hub 210. Like connectors 10, 110, eight-sided connector hub 210 has a plurality of lateral ports 212 that can receive connector pole(s). Connector 210 is annular in shape, with a central opening 214 passing therethrough. Within said opening 214 is a shelf 216, a neck 218 below and opposite shelf 216, and a pair of grooved walls 220 positioned to the sides of shelf 216 and neck 218, all of which components define opening 214. The function of these parts will be described hereinbelow. When used with only the pole connectors, connector hub 210 allows for placement of up to eight co-planar poles. For an improved friction fit, fingers 250 can be provided on the inner walls of ports 212.

[0065] FIGS. 23-25 show a two-point connector hub 310. In an embodiment, hub 310 is cylindrical in shape and has a pair of end ports 312, 314 which can receive pole connectors. The end ports 312, 314 can be dead end, or they can be interconnected. Extending from approximately the center of connector 310 is a pair of tabs 316. Each tab 316 has a pair of slots 318. In an embodiment of the present invention, two-point connector hub 310 is configured to dock inside central opening 214 of connector 210. In an unlocked configuration, tabs 316 sit on neck 218, which functions to prevent connector hub 310 from falling through connector hub 210. Connector 310 can then be locked into place within central opening 214 by rotating two-point connector hub 310 clockwise or anti-clockwise such that tabs 316 are in close proximity to grooved walls 220. When locked in place, connector 310 will be prevented from falling out in either direction by shelf 216 in one direction and neck 218 in the other. This first compound structure 320 can be seen in FIG. 30.

[0066] In some embodiments, slots 318 may interact with grooved walls 220 to secure the relative positions of connector hubs 210, 310. In further embodiments, preferred directions of rotation can be established via stops 222 on hub 210, which operate as impediments that prevent the rotation of connector hub 310 by catching tabs 316. For instance, stops 222 can prevent clockwise or anticlockwise rotation beyond the intended locked and unlocked configurations. Numerous other mechanical means for securing locked and unlocked positions can be implemented, beyond the enumerated examples. For an improved friction fit, fingers 350 can be provided on the inner walls of ports 312, 314.

[0067] In an embodiment two-point hub 310 can be provided with a window 322. This window can provide a user with visibility into the interior of two-point hub 310. This could be useful, for instance, to allow a user to see if an inserted pole (not shown) is fully inserted in end ports 312. Alternatively, window 322 can be gripped by spring fingers or mechanisms provided on another part to be connected to two-point hub 310 (e.g., when connected to the four-point hub described below). Another adaptation of two-point hub 310 to better interface with another part having fingers is the provision of a recessed area 324 on the exterior of two-point hub 310. A connecting mechanism can naturally occupy this space for a better fit and easier removal of connected parts.

[0068] When connector hubs 210 and 310 are in a locked position, the resulting compound structure 320 has the benefit of both lateral ports 212 and end ports 312, 314 perpendicular thereto. This exemplary compound hub structure therefore offers a total of ten different directions that connector poles can be extended from and lodged in.

[0069] FIGS. 26-29 show an additional, four-point connector hub 410 that can be provided, which can operate as an adapter. Hub 410 has angled ports 412 and a generally hemispherical shape. Connector 410 has a channel 414 passing therethrough. In isolation, connector hub 410 can be used to enable four different orientations of connector poles. In certain embodiments, channel 414 can receive a pole, providing a fifth port. For an improved friction fit, fingers 450 can be provided on the inner walls of ports 412 and/or 414. Particularly, spring fingers 416 in channel 414 can facilitate connection with two-point hub 310 by gripping recessed area 324.

[0070] In one embodiment, channel 414 can allow for an end port 312 of connector hub 310 to pass therethrough, forming an intermediate compound structure (not shown). The intermediate compound structure can be configured such that port 312 can still receive a pole connector while in such a configuration. Various modifications (e.g., ridges, slots, grooves, depressions, etc.) can be provided on connectors 310, 410 to resist relative moment therebetween or to otherwise secure connectors 310, 410 together; though in some embodiments, rotation of connector 410 about connector 310 may be desirable. In combination with connector 310, connector 410 effectively gains ports 312, 314 in addition to angled ports 412. Furthermore, while connected to connector 410, connector 310 can further interface with connector 210 as described hereinabove, forming a second compound structure 420 (see FIG. 31). Such a configuration would result in the provision of lateral ports 212 (i.e., eight more ports) to the compound structure hub 420.

[0071] To maximize interconnective possibilities, another hemispherical connector hub 410′ can be added to structure 420. This would be implemented by receiving the other port 314, in channel 410′ of the second hemispherical connector 410′. The resulting ball-shaped compound connector hub 510 (see FIG. 32) therefore has a total of sixteen (or in some embodiments, eighteen) different ports and directions in which it can receive a pole connector. In certain embodiments, angled ports 412′ can be symmetrical with respect to angled ports 412. Alternatively, angled ports 412 can be anti-symmetrical with respect to angled ports 412′, which would offer further customizability in terms of possible connections and constructed structures. In alternate embodiments, connector 210 can be omitted from connector hub 510, resulting in a third compound structure (not shown) of connector hubs 310, 410 and 410′ that lacks lateral ports 212.

[0072] In certain embodiments, connector hub 410 can be positioned on connector hub 310 in eight different positions (e.g., by rotating connector hub 410 in 45 degree increments). Implemented as such, the compound structures involving hubs 310, 410 would therefore be able to provide additional angles. In an embodiment, by rotating hemispherical connector 410 and/or hemispherical connector 410′, up to eight alternate angles could be achieved for a total of twenty- six possible orientations.

[0073] It will be understood that the embodiments described herein are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included within the scope of the invention.
