Best Mode for Carrying Out the Invention

FIGS. 1 and 2A illustrate an illuminated toy construction kit 10, which is constructed in accordance with an embodiment of the present invention. The kit 10 includes a plurality of illumination modules 12 (one of which is shown in FIGS. 1 and 2A), which may consist of a variety of shapes and sizes (see also, for example, FIGS. 7A through 7E). The kit 10 further includes a plurality of couplers 14, one of which is shown in FIGS. 1 and 2A. The couplers 14 may come in a variety of sizes and shapes (see also, for example, FIGS. 7F - 7I). Each of the illumination modules 12 includes a plurality of jacks 16, each being identical in size and shape to one another. As described in greater detail hereinbelow, the couplers 14 and the jacks 16 are adapted to facilitate the structural and electrical interconnection of the illumination modules 12 for the assembly of a variety of illuminated constructs and structures (see, for example, FIG. 8).

Referring specifically to FIG. 1 , the illumination module 12 includes upper and lower casings 18, 20 that are sized and shaped to interconnect with each other to form a housing 22. The upper casing 8 is depicted as being fabricated from transparent material and the lower casing is depicted as being fabricated from an opaque material although the lower casing 20 may also be fabricated from transparent material. The upper and lower casings 18, 20 have abutting arcuate lugs 24a, 24b, respectively, that cooperate to cradle a receptacle (i.e., receiving) end 25 of a corresponding one of the jacks 16 such that the receptacle end 25 is recessed within the housing 20. The receptacle end 25 of the jack functions as a female-like socket in a manner to be described in greater detail hereinafter. The housing 22 is adapted to support at least one printed circuit board assembly 26 ("the PCBA 26") in the interior thereof. The housing 22 also includes a plurality of openings 27, each of which is (i) provided in a corresponding sidewall of the housing 22 and (ii) aligned with a corresponding one of the jacks 16 in order to provide access for the couplers 14 to interconnect with the jacks 16 in a manner to be described hereinafter. In an embodiment, the upper and lower casings 18, 20 may be fabricated from transparent (i.e., clear) or translucent polymer material, and may be permanently joined together with an adhesive or glue to form the housing 22. Alternatively, the upper and lower casings 18, 20 may be fabricated with clips (not shown) to releasably join the upper and lower casings 18, 20 to one another to form the housing 22. As a further option, one of casings 18, 20 may be made from an opaque material, while the other is made from a transparent or translucent material.

Still referring to FIG. 1 , the PCBA 26 includes a printed circuit board

28 ("the PCB 28") having conductive pathways or tracks 30, 32 positioned on a non-conductive substrate 34. In an embodiment, the tracks 30, 32 may be etched on the substrate 34 by conventional production methods and facilities known in the art. A light-emitting element 36, which includes power leads 38, 40, Js mechanically supported by and electrically connected to the PCB 28. In an embodiment, the light-emitting element 36 is a conventional, color-varying light-emitting diode (LED). In other embodiments, the light-emitting element 36 can be any type of light bulb or similar device capable of generating light. The leads 38, 40 of the light- emitting element 36 may be soldered to the PCB 28 by conventional methods and facilities known in the art. More particularly, as shown in FIG. 1, the power lead 38 is soldered to the track 30, and the power lead 40 is soldered to the track 32.

In an embodiment, each of the jacks 16 is mechanically and electrically connected to the PCB 28 by conventional methods and facilities known in the art. More particularly, each of the jacks 16 is positioned between the PCB 28 and a corresponding one of the openings 27 of the housing 22. As indicated above, the receptacle end 25 of each of the jacks 16 is recessed within the housing 22. Referring to FIGS. 1 and 2B, each of the jacks 16 includes a tubular-shaped electrical conductor 42, which is fastened to the substrate 34 and is soldered to the track 32. Each of the jacks 16 further includes a pin-shaped electrical conductor 44, which is fastened to the substrate 34 and soldered to the track 30. An insulator 46 (see FIG. 2B) electrically separates the conductor 42 from the conductor 44.

The PCBA 26, by virtue of the its electrical conductivity, enables an electromotive force (emf) of, for example, +4.5 volts, that is applied across the conductors 42, 44 to appear across the leads 38, 40 of the light- emitting element 36, as well as across the conductors 42, 44 of each of the jacks 16. More particularly, emf may be applied across the conductors 42, 44 of one of the jacks 16 by a power plug P (see FIG. 1 ) that is connected to a direct current power supply PS (see FIG. 1), such as a battery, which can be located externally of a structure formed from the illumination modules 12 and the couplers 14 or which can be self-contained on such structure. The power plug P enables emf that appears across the anode (i.e., +) and the cathode (i.e., -) terminals of the battery or other direct current power supply to appear across all of the conductors 42, 44, respectively, of all of the jacks 16. In this manner, the illumination module 12 is "energized", the light-emitting element 36 is illuminated, and emf is applied across all of the conductors 42, 44, respectively, of all of the jacks 16. In other words, the conductors 42, 44 of the "energized" illumination module 12 may be utilized to energize other illumination modules 12 via the couplers 14. The use of the couplers 14 to structurally interconnect and electrically energize other illumination modules 12 is described hereinafter, following a more detailed description of the coupler 14 which is provided immediately below.

Referring to FIG. 2C, the coupler 14 has a pair of opposed male-like (i.e., plug) ends 47a, 47b, whose function will be described in greater detail hereinafter. The coupler 14 also includes a tubular-shaped inner conductor 48, which may be fabricated from metal, a tubular-shaped outer conductor 50, which may be fabricated from metal (e.g., zinc-coated brass), and a tubular-shaped insulator 52, which separates the inner and outer conductors 48, 50 from one another. The insulator 52 may be fabricated from a polymer, such as .PVC or polyurethane. In an embodiment, a coliar-like grip 54 is over-molded on the center of the outer conductor 50 of the coupler 14. The grip 54, which facilitates the handling of the coupler 14, may be fabricated from a polymer, such as PVC or polyurethane. In an embodiment, the grip 54 is in the shape of a ring, having a size and shape that enables it to fit snugly within two contiguously positioned (i.e., adjacent or substantially abutting) openings 27 of two contiguously positioned (i.e., adjacent or substantially abutting) illumination modules 12, thereby providing structural stabilization and electrical continuity to the interconnected illumination modules 12 (see, for example, FIGS. 3 and 9C), which modules would be rotatable relative to the coupler 14 and hence relative to each other. Couplers 14 made according to embodiments of the present invention allow the interconnected illumination modules 12 to be rotated relative to each other by 360 degrees of rotation or more when the illumination modules 12 are connected by a coupler 14.

In an embodiment, the length of the grip 54 is elongated in the longitudinal direction (see FIGS. 3 and 7 J) so that a portion of its exterior surface is revealed between two interconnected illumination modules 12, which would therefore be maintained in a spaced-apart relationship by the elongated grip. The exposed portion of the elongated grip may also be formed with decorative designs (see, for example, the three-bladed propeller shown in F!G. 15). Such a coupler may, therefore, serve as a non-illumination module, that could be utilized in conjunction with the illumination modules 12, ¾as well as with other compatible non-illumination modules, such as LEGO® brick elements, as will be described in greater detail hereinbelow.

With reference to FIG. 2D, the couplers 14 and the jacks 16 are sized and shaped to have snug-fits when they are interconnected with one another, thereby providing additional structural stability to the combination. More particularly, the free end 25 of the jack 16 functions as a female-like socket to releasably and rotatably receive the male-like (i.e., plug) end 47a of the coupler 14. By virtue of (i) the electrical continuity of the inner conductor 48 of the coupler 14 being in contact with the electrical conductor 44 of the jack 16 and (ii) the electrical continuity of the outer conductor 50 of the coupler 14 being in contact with the electrical conductor 42 of the jack 16, each of the couplers 14 can function, in use, to convey emf across the conductors 42, 44 of the jacks 16 of two interconnected illumination modules 12.

FIG. 3 illustrates an assembly made from the toy construction kit 10, which assembly includes three of the illumination modules 12 interconnected by two of the couplers 14, which function as mechanical linkages. Assuming that at least one of the illumination modules 12 is energized in the manner described hereinabove, the other two modules 12 are energized as a result of their interconnection via the couplers 14, which also function as electrical conduits to transfer electric power between all of the interconnected illumination modules 12 such that all three of the light- emitting elements 36 can be simultaneously illuminated. As shown in FIG. 3, the illumination modules 12 are oriented such that their planar surfaces are in the same plane (i.e., they are coplanar), forming a relatively flat structure. In another embodiment, which is represented in phantom in FIG. 3, the couplers 14 permit two contiguously positioned (i.e., adjacent or substantially abutting) illumination modules 12 to be rotated relative to one another, in the direction of the arrow R, thereby expanding the possibilities of constructing various types of constructs and structures with the kit 10. The coupler 14', which is shown in exploded fashion, has an elongated grip 54' as described hereinabove.

Each of the illumination modules- 412 also includes upper and lower casings 418, 420, which have upper mounting retainers 421a and lower mounting retainers 421b, respectively. When the upper and lower casings 418, 420 are interconnected, the upper mounting retainers 421a cooperate with the lower mounting retainers 421b to support an assembly 481 comprising cathode and anode plates 483, 485, respectively, and an electrical insulating layer 487 sandwiched therebetween. The insulating layer 487 supports a light-emitting element 436.

In an embodiment, the upper casing 418 of the illumination module 412 includes a plurality of projections 489 extending outwardly therefrom. Likewise, the lower casing 420 of the illumination module 412 includes at least one receptacle 491 formed therein. The receptacle 491 is sized and shaped to snugly receive the projections 489 of the upper casing 418 of another illumination module 412. Additionally, or alternatively, the illumination modules 412 may be assembled with elements of other toy construction components, such as LEGO^® brick elements (not shown), which typically would not have their own self-contained light source, but which would have complementary projections and/or receptacles that are capable of mating with the projections 489 and/or the receptacle 491 of the illumination module 412. More particularly, projections on other toy construction components may be releasably received in the receptacle 491 of the lower casing 420. Likewise, the projections 489 of the upper casing 418 may be releasably inserted in a mating receptacle in another toy construction component, which, if transparent or translucent, could be used to transmit light emanating from the illumination module 412 to additional, otherwise non-illuminated, toy construction components. With reference to FIG. 12, a power supply module 510 has a top casing 512 that is releasably connected to a bottom casing 514. The top casing 512 has a top surface 516 with a series of projections 518 formed thereon that are sized and shaped so that the power supply module 510 can be releasably connected to one or more of the illumination modules 412 or to a compatible non-illumination module, such as LEGO® brick elements. The top casing 512 also has side surfaces 520 and end surfaces 522, each of which is void of projections like the projections 518. The bottom casing 514 has a bottom surface 524 with a series of projections (not shown) that are like the projections 518 on the top casing 512, whereby the power supply module 510 can be releasably connected to additional illumination modules 412 or to other compatibie non- illumination modules, such as LEGO® brick elements. The bottom casing 514 also has side surfaces 526 and end surfaces 528, each of which is void of projections like the projections 518.

The power supply module 510 has one or more batteries mounted therein (not shown) which are electrically connected to a plug P" by wires (not shown). An ON/OFF switch (not shown), which may be positioned on the bottom surface 524, is installed in the wiring connecting the batteries to the plug P" in order to electrically connect/disconnect the batteries to/from the plug P'. The plug P' is sized and shaped, and is mechanically and electrically constructed, in the same manner as the plug P of FIG. 1. Therefore, the plug P' is mechanically and electrically connectable to the jacks 16 and 116 of FIGS. 1 and 4, respectively. It is understood, therefore, that since the plugs P', P are mechanically and electrically connectabie to the jacks 16 and 116, the plugs P' and P cannot be connectable in any manner {e.g., mechanically or electrically) to the couplers 14 and 114 of FIGS. 1 and 4, respectively. In other words, the plugs P¹, P are compatible with the jacks 16 and 116, but they are not compatible with the couplers 14 and 114. Needless to say, the plugs P', P could be modified so that they are compatible with the jacks 216, 316, and 416, instead of the jacks 16 and 116, in which case they would be incompatible with the couplers 214, 314, and 414, as well as the couplers 14 and 114.

As disclosed above, the power supply module 510 may be releasably connected to one or more of the illumination modules 412 or to one or more compatible,: non-illumination modules, such as LEGO® brick elements, via the series of projections 518 formed on the power supply module 5 0. The power supply module 510 may also be connected to one or more illumination modules 12 and 112 via the mechanical and electrical interconnection between the jacks 16 and 116 and the plug P'_t it being understood that there may be more than one plug P' and that one or more of the additional plugs could be connected to one or more of the illumination modules 212, 312, and/or 412. The plug P' could also be omitted and replaced with one of the projections 518, in which case a tethered plug (see, for instance, FIG. 16) could be employed to connect the power supply module 510 to the illumination modules 12, 112, on the one hand, or to the illumination modules 212, 312, and 412, on the other hand. The power supply module 510 is therefore capable of supplying electric power to any of the illumination modules 12, 112, 212, and 312, and 412. In an embodiment, the power supply module 510 may be powered by the DC-output of an AC transformer that is positioned either internally or externally of the power supply module 510.

As disclosed above, the power supply module 510 may also be releasably connected to one or more compatible non-illumination modules, such as LEGO® brick elements, via the series of projections 518 formed on the power supply module 510. For example, with reference to FIGS. 13 and 14, a model of a jet fighter plane is constructed around the power supply module 510, which therefore forms part of the model and functions as a non-illumination module therein. FIG. 13 shows non-illuminated decorative components such as wheels 530 and engine nacelles or housings 532 {depicted in phantom) fastened to the projections 518 of the power supply module 510. FIG. 14 shows additional decorative components fastened to the power supply module 510, such as wing elements 534, rudder elements 536, cockpit 538 and nose cone 540.

As disclosed above, the couplers 14, 114, 214, 314 and 414 of FIGS. 1 , 4, 9A, 10B and 11 A, respectively, may have various decorative designs and shapes. For example, referring to FIG. 15, a coupler 610 is shown in the form of a propeller. More particularly, the coupler 610 includes a propeller hub 612 having three blades 614. The coupler 610 also has a nose component 616, which extends outwardly from the front of the propeller hub 612, and a rear component 618, which extends outwardly from the rear of the hub 612. The nose and rear components 616, 618, respectively, are sized and shaped, and function in the same manner as, the opposed male-like (i.e., plug) ends 47a, 47b of the coupler 14 shown in FIGS. 1 , 2A, 2C, 2D and 3. As a result, the coupler 610 may be mounted in one or more of the jacks 16, 116, 216, 316, and 416 of the illumination modules 12, 112, 212, and 312, and 412, respectively, via the nose and rear components 616, 618, respectively. Since the coupler 610 does not have a light source, it functions as a non-illumination module, just as the couplers 14, 114, 214, 314 and 414 may function as non-iilumination modules.

Referring to FIG. 16, a power supply 710 has, on its bottom or back surface, an ON/OFF switch 712 which controls a direct current power source such as: i) batteries (not shown) that are releasably mounted internally of the power supply 710; or ii) the direct current output of an alternating current transformer that is positioned externally of the power supply 7 0. The top or front surface (not shown) of the power supply 710 is provided with (i) projections like the projections 518 or (ii) a series of circular rings that would function in a manner similar to the projections 518. A power cord 714 extends from the power supply 710 to a power plug 716, which is sized and shaped, and is mechanically and electrically constructed, in the same manner as the couplers 214, 314 and 414 of FIGS. 9A, 10A and 11 B, respectively. As a result, the plug 716 is mechanically and electrically connectable to the jacks 216, 316, and 416 of FIGS. 9A, 10A, and 11 B, respectively. It is understood, therefore, that since the plug 716 is mechanically and electrically connectable to the jacks 216, 316, and 416, the plug 716 cannot be connected in any manner (e.g., mechanically or electrically) to the couplers 214, 314, and 414, respectively. In other words, the plug 716 is compatible with the jacks 216, 316, and 416, but it is not compatible with the couplers 214, 314, and 414. Needless to say, the plug 716 could be modified so that it is compatible with the jacks 16 and 116, instead of the jacks 216, 316, and 416, in which case it would be incompatible with the couplers 14 and 1 4, as well as the couplers 214, 314, and 414. Optionally, the power supply 7 0 may be provided with special effects circuitry offering a variety of functions, such as voice activation or some other form of remote control, disco lighting, strobe lights and/or sound generation, including music. Such special effects circuitry may be accessed via a Mini USB plug (not shown) located on an exterior surface of the power supply 710. Similar special effects features could, of course, be provided on the power supply module 510.

As disclosed above, the upper casing 418 of the illumination module 412 includes a plurality of projections 489 extending outwardly therefrom, and the lower casing 420 includes at least one receptacle 491 formed therein. Also disclosed above, the power supply module 510 has a top casing 512 with a series of projections 518 formed thereon that are sized and shaped so that the power supply module 510 can be releasably connected to one or more of the illumination modules 412 or to a compatible non-illumination module, such as LEGO® brick elements. As exemplified in the embodiment described below and depicted by FIGS. 17- 19, in order to establish greater releasable connectability (i.e., the projections of one module are releasably connectable to the receptacles of another module), the upper casings 18, 118, 218, and 318 of the illumination modules 12, 112, 212, and 312, respectively, may be provided with a plurality of projections. Likewise, as disclosed in the embodiment below, the lower casings 20, 120, 220, and 320 of the illumination modules 12, 112, 212, and 312, respectively, may be provided with a plurality of receptacles. As a result, a great variety of three-dimensional structural shapes may be formed (see, for example, FIG. 24). More particularly, as exemplified in the embodiment below, three dimensional structural shapes may include combinations of the illumination modules 12, 112, 212, 312, and 412, the power supply modules 510, and compatible non-illumination modules.

FIGS. 17 -19 illustrate an illumination module 812 that has a housing 822 with upper and lower casings 818, 820. The upper casing 818 has a construction similar to the upper casing 18 of the embodiment of FIGS. 1 - 3 as well as the upper casing 118 of the embodiment of FIG. 4, except that the upper casing 818 has a plurality of projections or studs 850 that are symmetrically formed the!reon. It is to be understood that the upper casing 818 is similar in construction to upper casing 18 (see FIGS. 1-3) and upper casing 118 (see FIG. 11 B) except for the presence of the plurality of studs 850 on upper casing 818, For example, upper casings 18, 118, 818 may all be made of transparent material. For the purpose of clarity, no interior elements of the illumination module 812 and other illumination modules of similar construction are depicted in FIGS. 17 -23.

Referring to FIG. 17, the upper casing 818 has a surface 848 on which the studs 850 are formed. The size and shape of the studs 850 are similar to the size and shape of the projections 489 of the illumination module 412. More particularly, each stud 850 has a cylindrical ly-shaped side wall surface 854 that has a diameter D1 and is oriented perpendicular to the plane of the surface 848. The stud 850 has a flat top surface 856 that is oriented in a plane that is parallel with the plane of the surface 848. The studs 850 are arranged in a 4x4 array, with the minimum distance between adjacent studs 850 being a distance L1, and the interstitial spaces between adjacent studs 850 being generally designated as interstices S. It is understood that other embodiments may have other arrays of studs 850 (e.g., 3x3, 5x5, etc.). A arcuate lug 824a is formed in the upper casing 818, for purposes that are described above in relation to the lug 24a.

Referring to FIG. 18, the lower casing 820 has a construction similar to the lower casing 20 of the embodiment of FIGS. 1 - 3 as well as the lower casing 120 of the embodiment of FIG. 4, except that the lower casing 820 has a plurality of receptacles 852 that are symmetrically formed on a surface 858 of the lower casing 820. Each receptacle 852 has a tubular- shaped clasp 860. The clasp 860 has an outer surface 862 that has a diameter D2, and an inner surface 864. The outer and inner surfaces 862, 864 are oriented perpendicular relative to the surface 858. The clasp 860 has a thickness T, which determines the flexible resilience of the clasp 860 in the radial direction. I^ore particularly, a stress, such as a force exerted by a press fit of the side wall surface 854 of the studs 850, in the radial direction, on the outer surface 862 of the clasp 860 results in a strain (i.e., a minute displacement) of the clasp 860 in the radial direction. In turn, the strain on the clasp 860 produces a stress that is exerted by the clasp 860 and has a magnitude that is equal to the magnitude of the stress S and acts in a radial direction opposite to the direction of the stress. The stress/strain relationship (i.e., the flexible-resilience of the clasp 860) is a function of the thickness T of the clasp 860 and the material of which the clasp 860 is made of. Therefore, the selection of the thickness T of the clasp 860 (e.g., for a particular clasp 860 material such as a plastic) is a primary factor in determining the strength of the press-fit connections between the studs 850 and the receptacles 852.

Although the illumination module 812 has a plurality of studs 850 that are symmetrically formed on the surface 848 of the upper casing 818, and a plurality of receptacles 852 that are symmetrically formed on the surface 858 of the lower casing 820, it is understood that the illumination module 812 may having¾ plurality of studs 850 formed on the upper casing 8 8, while having no receptacles 852 formed on the lower casing 820. It is also under stood that the illumination module 812 may have a plurality of receptacles 852 formed on lower casing 820, while having no studs 850 formed on the upper casing 818.

A rim 868 that has a flat top surface 870 is formed around the perimeter of the surface 858 of the lower casing 820. The receptacles 852 are arranged in a 3x3 array, with the minimum space between adjacent clasps 860 being a distance L2. The interstitial space that exists between adjacent clasps 860 is designated generally as interstices C. The clasps 860 that are adjacent to each other and the clasps 860 that are adjacent to the rim 868 must be spaced away from each adjacent clasp 860 or rim 868 such that a stud 850 may fit securely in any interstice C by a press-fit with some of the clasps 860 or with one or more clasps 860 and the rim 868. It is understood that other embodiments of the module 812 may have different arrays of clasps 860 (e.g., 4x4, 5x5, etc.). An arcuate lug 824b is formed in the lower casing 820, for purposes similar to those that are described above in relation to the lug 24b.

Referring to FIGS. 20A and 20 B, in alternate embodiments of the present invention, the illuminated module 812 can be made in various shapes and sizes other than the rectangular shape shown by FIGS. 17 - 9. For example, FIG. 20A illustrates an illumination module 812a having a rounded rectangular shape. FIG. 20B shows an illumination module 812b having the shape of an equilateral triangle.

Referring now to FIGS. 21-23, FIG. 21 is a top-perspective view of four illumination modules 812A, 812B, 812C and 812D of the present invention that are connected to each other to form a three-dimensional structure 872. FIG. 22 is a cross-sectional profile view of the structure 872. FIG. 23 is a top plan view of the structure 872 with illumination modules 812A and 812B and their respective studs 850A and 850B shown as ghost images such that the features of illumination module 812C are clearly visible. Since FIGS. 21 -23 represent different views of a structure 872, references to the respective elements of structure 872 should be considered with reference to FIGS. 21 -23 in combination with each other.

Continuing to refer to FIGS. 21-23, the stress / strain mechanism affords the press-fit connectability by press-fit connecting four studs 850A of module 812A against the outer surfaces 862C of four clasps 860C of the module 812C and the rim 868C of the module 812C. The studs 850A occupy the interstices C of the module 812C, and the clasps 860C occupy the corresponding interstices S (shown in FIG. 17, but omitted here for sake of clarity) between the studs 850A. Likewise, four studs 850B of modules 812B are press-fit connected with the outer surfaces 862C of another four clasps 860C of the module 812C and the rim 868C of the module 812C. The studs 850 B occupy additional interstices C of the module 812C, and the clasps 860C occupy the corresponding interstices S (shown in FIG. 17, but omitted here for sake of clarity) between the studs 850B. In addition, stud-like projections of compatible non-illumination modules, such as LEGO® brick elements (not shown) may be press-fit connected on the inner surfaces 864 of the clasps 860. In this manner the user may assemble three dimensional structures involving illumination modules 812 as well as non-illumination modules.

The aforementioned principles can also be applied to assemble modules like modules 812A, 812B, 812C into columns, pyramids, and other arrangements. Other modules having different shapes, or having different numbers of studs similar to studs 850A, 850B, 850C, or having different numbers of clasps similar to clasps 860A, 860B, or 860C, can also be assembled into structures having simple or complex geometries. A wide variety of suitable structures will be recognized by those having ordinary skill in the relevant arts.

As disclosed above, the couplers 114 may include flexible elements (see, e.g., FIG. 7 J) that enable the couplers 114 to have various shapes and orientations. FIGS. 24A-24C illustrate flexible couplers 914A, 914B and 914C, respectively, which are fashioned according to exemplary embodiments of the present invention. Couplers 914A, 914B and 914C are constructed, assembled and function in the same basic manner as each other, except that they vary in length. It is understood that the couplers 914A, 914B and 914C may be constructed in lengths that are greater or less than the lengths depicted in FIGS. 24A -24C. Since the couplers 914A, 914B and 914C are substantially identical except for their overall lengths, only the coupler 914A is described in detail below. Corresponding elements of the coupler 914A, 914B, 914C are indicated in FIGS. 24A-24C by reference numbers that correspond to those used in conjunction with coupler 914A, and which differ from those used in conjunction with coupler 914A by substitution of the letters B or C for the letter A.

In an embodiment, the coupler 914A has a pair of opposed male-like (i.e., plug) ends 947A, 947 A*. The plug ends 947A, 947A' each include a respective tubular-shaped inner conductor 948A, 948A', a respective tubular-shaped outer conductor 950A, 950A', which may be co-axial with the respective inner conductor 947 A, 947A', and respective tubular-shaped insulators (not visible), which separate and electrically insulate the respective inner and outer conductors 948A, 948', 950A, 950A' from one another. Collar-like grips 955A, 955A' are fastened to the respective plug ends 947A, 947 A. The coupler 914A includes a flexible connector 980A which mechanically and electrically connects the plug ends 947A, 947A' to each other. The plug ends 947A, 947A' are constructed such that illumination modules of. the present invention, as heretofore described, when coupled by the flexible coupler 914A can be rotated relative to each other by 360 degrees of rotation or more without straining the flexible connector 980A.

Turning to the flexible connector 980A, the flexible connector 980A provides the electrical connection between the plug ends 947A, 947A' by means of at least a first elongated flexible electrical conductor {not shown) and a second elongated flexible electrical conductor (not shown) which are within the flexible connector 980A and electrically insulated from each other. The first and second flexible electrical conductors should be formed so as to withstand repeated flexing without breaking. Each of the first and second flexible electrical conductors has respective first and second ends. Each end of the first flexible electrical conductor may be electrically connected to a respective one of the tubular-shaped inner conductors 948A, 948A', and each end of the second flexible electrical conductor may be electrically connected to a respective one of the tubular-shaped outer conductors 950A, 950A. In some embodiments of the present invention, the respective eiectrical connections may be made by soldering an end of the flexible electrical connector to its respective tubular conductor 948A, 948A, 950A, 950A'.

In some embodiments of the present invention, the flexible electrical conductors may be metal wires in electrically-insulating sheaths, such as are well-known in the art. In other embodiments of the present invention, the second flexible electrical conductor may surround the first flexible electrical conductor in a coaxial arrangement with an electrical insulator between the first and second flexible conductors. The first and/or second flexible conductors may be fabricated from a multiplicity of thin flexible metallic strands in order provide electrical conductivity and a high degree of physical flexibility (i.e., the flexible electrical conductors are easily bendable by hand). The multiplicity of thin flexible metallic strands enable the first and/or second flexible electrical conductors to resist fatigue-failures of the strands (e.g., due to repeated bending, twisting, etc.). The strands maybe configured in twisted, braided, interwoven or other configurations in order to increase the tensile strength of the first and second flexible electrical conductors and to further resist fatigue-failures of the strands. The metallic strands may be made of copper or they may be made of another suitable electrically conductive material such as aluminum.

The flexible connector 980A has an outer covering 952A which protects the interior of the flexible connector 980A from the intrusion of dirt and / or fluids into its interior. Fasteners 955A are crimped around the cover 952A, proximate the plug ends 947A, 947 A', to facilitate the mechanical connection of the wire 980A to the plug ends 947A, 947A' as well as to provide strain relief for the plug ends 947A, 947A'.

In use, referring to FIG. 25, the flexible coupler 914C is shown electrically connecting the three-dimensional illuminated structure 872 (discussed above in relation to FIGS. 21-23) to the three-dimensional illuminated structure 110 (shown in FIG. 8). More particularly, the plug end 947C of the flexible connector 980C is inserted in the arcuate lugs (not visible) of the module 112, and the plug end 947C is removeably inserted in the arcuate lugs (not visible) of the module 812B, thereby establishing electrical connectivity between the illuminated module 812B and the illumination module 112. An additional illumination module 812 may be connected to illumination module 812A using a connector 14. A power source PS provides electrical power to the assembly at structure 110.

It should be appreciated that the present invention provides numerous advantages. For instance, the jacks 16 of the illumination modules 12 (see, e.g., FIG. 2A) are identical in size and shape to one another, thereby facilitating ease of use in assembling and disassembling the illumination modules 2 of the kit 10. Utilizing identically-shaped jacks 6 also minimizes the overall number of parts required to produce the kit 10, as well as minimizing the cost to produce the kit 10. Furthermore, the kit 10 may feature the illumination modules 12, 112, 212, 312, 412, 812 and the couplers 14, 114, 214, 314, 414, 914A, 914B, 914C consisting of various sizes and shapes as described above. Further the illumination modules 12, 112, 212, 312, 412, 812 and couplers 14, 214, 314, 414, 914A, 914B, 91 AC are constructed such that coupled illumination modules can be rotated by 360 degrees of rotation or more relative to each other without straining or damaging the coupler 14, 214, 314, 414, 914A, 914B, 91 C. An individual is, thus, able to construct from these components a wide array of forms (e.g., cars, buildings, aircrafts, tanks, science-fiction devices, etc.) having fascinating shapes and aesthetic light-emitting characteristics. In addition, the illuminated toy construction kits 310 and 410 employ printed-circuit-board-less assemblies 369, 481 , respectively, which are useful if the production requirements of the kits 310, 410 do not require the use of printed circuit board assemblies, such as those employed in the illuminated toy construction kits 10, 110, and 210. Also, the upper and lower casings 418, 420 of the illumination module 412 (see, e.g., FIGS. 11A and 11 B), and the upper and lower casing 818, 820 of the of the illumination modules 812 (see, e.g., FiGS. 21-23) facilitate interconnection among the illumination modules of the present invention as well as with compatible non-illumination module, such as LEGO® brick elements, thereby further extending the array of novel illuminated toy assemblies that an individual may construct.

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, in addition to those described above, are intended to be included within the scope of the invention as defined in the appended claims.
