Field of the Invention

[0002] The present invention relates to powered toy building structures, and more particularly, to toy building structures that, when assembled, transmit power for various functions via connections between the structures.

Backgiround of the Invention

[0003] The present inventor has previously invented illuminated toy building structures, in which a plurality of blocks or other building elements are assembled by connections that double as electrical connections. In this manner, a plurality of illuminated blocks can be powered from a single power source, giving relatively free reign to the imagination of users to assemble to large numbers of blocks into a wide range of models. Examples of such blocks can be seen in the present inventor's U.S. Patent No. 7,731 ,558 and U.S. Patent Application Serial No. 12/547,183, the contents of which are herein incorporated by reference in their entirety. [0004] Despite the popularity of these illuminated building structures, further improvements are possible, both with respect to the illuminated building structures themselves, and in devices for use therewith.

Detailed Description of Preferred Embodiments

[0019] According to an embodiment of the present invention, referring to Figure 1 , a powered toy building structure assembly 10 includes a plurality of releasabiy interconnected toy building blocks 12 powered by a power supply 14. A power cable 18 can be used to releasabiy connect the blocks 12 to the power supply 14, or the blocks 12 can releasably connect directly to the power supply 14. Once single block 12 is connected to the power supply 14 and the power supply 14 is energized, every other block 12 connected directly or indirectly thereto will receive electrical power from the power supply 14 to power electrical components therein; for instance, for illumination, the playing of sounds, or other functions.

[0020] The present invention is not necessarily limited to the shaped of blocks 12 shown in Figure 1 , and combinations of blocks 12 can be assembled info virtually any design imaginable, Additionally, other power supplies 14 can be employed in connection with the blocks 12; for example, as disclosed in the previously referenced patent and patent application of the present invention. Such power supplies 14 can supply either a steady, continuous power, or supply power in one or more

predetermined patterns.

[0021] Referring to Figure 2, an exemplary one of the blocks 12 is shown. It will be appreciated that the following description of features of the exemplary block 12 could be readily applied to any of the blocks 12 shown, as well as to blocks 12 of other shapes and configurations.

[0022] The block 12 includes a printed circuit board 20 to which one or more electrical components 22, 24 are mounted, such as a lighting emitting diode (LED) 22 and resistor 24. A plurality of electrical connectors 26, 30 are mounted to edges of the circuit board 20 and electrically connected to the electrical components 22, 24. The electrical connectors 26, 30 are preferably male and/or female coaxial electrical connectors, such that an electrical circuit including the electrical components 22, 24 can be completed by connecting any single connector 28, 30, as illustrated in the circuit diagram of Figure 3.

[0023] Advantageously for use with the LED 22, a circuit board opening 32 Is defined extending between opposite surfaces of the printed circuit board 20, In the depicted block 12, the opening 32 is completely surrounded by the circuit board 20. Preferably, at least a majority of the opening 32 is surrounded by the circuit board 20; for example, the opening 32 could be bounded on three sides by the circuit board 20. The LED 22 is mounted over the opening 32, allowing the LED 22, and light emitted therefrom, to be seen from both sides of the circuit board 20. The LED 22 can be mounted so as to extend into the opening 32, thus decreasing the effective space required within the block 12 by the LED 22.

[0024] It will be appreciated that, by assembling the electrical components 22, 24 and connectors 28, 30 onto the printed circuit board 20, the assembly time for the building structures 12 can be decreased and the accurate placement of electrical components can be simultaneously facilitated. The circuit board 20 also includes a circuit board alignment element 34. The circuit board alignment element 34 can help ensure proper placement of the circuit board 20 within the block 12, as will be explained in Greater detail below.

[0025] The block 12 also includes a body 36, which is advantageously generally transparent so that the interior components can be seen therethrough, although non- transparent bodies 38, or bodies 38 with only limited areas of transparency or translucency can be used within the scope of the present invention. The body 36 is preferably formed of two portions, a top portion of which is removed in Figure 2 to better show internal details of the block 12. The body 38 defines a holiow interior cavity 40 between the portions when connected, in which the printed circuit board 20 is arranged.

[0026] The body 36 includes mechanical connectors 42, 44, such as male connectors 42 and female connectors 44, extending outwardly from the interior cavity 40. With the printed circuit board 20 properly placed in the interior cavity 40, the electrical connectors 26, 30 extend into respective mechanical connectors 44, 42.

Thus, a single mechanical connection between adjacent blocks 12 suffices to make a complete electrical connection therebetween.

[0027] To help ensure proper placement of the circuit board 20, a body alignment element 48 is formed in the interior cavity 40 that is complementary with the circuit board alignment element 34. With the circuit board and body alignment elements 34, 46 in complementary engagement, the circuit board 20 will be properly placed within the body 12. Advantageously, the circuit board 20 will physically not fit in the interior cavity 40 unless complementary engagement is achieved, mechanically inhibiting connection of the body 36 portions until the correct placement is achieved.

[0028] Referring to Figures 4 and 5, an alternate block embodiment will be described. In referring to alternate embodiments, like reference numerals are used to refer to like elements, annotated with one or more prime ( ^! ) notations. The block 12' of Figures 4 and 5 is an audio-capable block, and includes printed circuit board 20' with a digital audio player 50' mounted thereon, and at least one electrical connector 30' mounted to an edge thereof and electrically connected to the digital audio player 50'.

[0029] The digital audio player 50 ^! includes a memory device on which one more digital audio files can be stored for playing via a speaker 52'. Advantageously, a plurality of openings 54' can be defined through the body 38' to better allow the speaker 52' to be audible therethrough.

[0030] The digital audio player 50' can be pre-loaded with one or more audio files, and automatically play such fiie(s) when power is applied to the block 12 ^! .

Alternately, another actuation method could be applied to trigger the playing of digital audio files, such as sound or motion activation, or an electrical switch, A plurality of different blocks 12' could be packaged together into a kit, with each block 12' featuring a different pre-loaded digital audio file.

[0031] Referring to Figure 8, a block 12" can further be equipped with a data connector 60" accessible via a data connector port 62" in the body 36", such a micro universal serial bus (micro-USB) connector. A user can upload audio data files to the memory device of the digital audio player via the data connector 80". The present invention is not necessarily limited to any particular type of digital audio player, to any type of digital audio file, to any type of data connector, or to any particular audio date file transfer regime. In addition to their audio capabilities, the blocks 12', 12" can also be illuminated.

[0001] The audio blocks 12' and 12" can readily be connected to the power supply 14 (with or without cable 16) and to other blocks 12, such as illuminated blocks 12, to further increase the excitement and design possibilities for powered toy building structure assemblies.

[0002] In general, the foregoing description is provided for exemplary and illustrative purposes; the present invention is not necessarily limited thereto. Rather, those skilled in the art will appreciate that additional modifications, as well as adaptations for particular circumstances, will fall within the scope of the invention as herein shown and described and of the claims appended hereto.
