Cross-reference to related applications
[0002] The application claims priority to U.S. Provisional Application Serial No. 62/546,072, filed August 16, 2017 herein incorporated by reference in its entirety.
Background of the Invention
[0003] The present invention generally relates to the field of building blocks. More particularly, the invention relates to a system of conductive magnetic building blocks.
[0004] Many different iterations of building blocks exist in the prior art. Blocks can be classified broadly according to the type of materials used in manufacture and the functionality offered. Ease of use and manipulation are also factors in how appealing and engaging the blocks will be to the end user.
[0005] Wooden blocks, for instance, are made of an environmentally safe material and are easy to use and manipulate, but often do not support much additional functionality. For example, wooden blocks can be stacked and aligned, but do not inherently offer structural stability without the use of alignment pins or adhesives. If alignment pins or adhesives are used, the blocks become hard to take apart and rebuild with.
[0006] Other building blocks in the prior art include LEGO blocks or LEGO style blocks. LEGO style blocks typically comprise a set of colorful interlocking plastic bricks. LEGO style blocks typically comprise a male and female component that fit together with a compression fit. The LEGO style block may be difficult to manipulate for those lacking in fine motor strength and difficult to pull apart once connected to each other. These drawbacks spurred the development of other block designs such as magnetic blocks.
[0007] Magnetic blocks allow the end user to easily combine or stack blocks into complex structures. Typical magnetic blocks such as MAGNATILES or TEGU blocks embed magnets beneath the surface of plastic or wood at the respective edges of each block. A user with even minimal fine motor strength can easily manipulate the blocks to attract to one another and build support structures that are magnetically coupled. The stronger and higher quality magnets used typically offer better user experiences.
[0008] Still yet another evolution of the building block has been in the conductive style building block i.e. building blocks that conduct electricity for the purpose of powering an electrical element such as an LED, a speaker, or a motor. This has been accomplished in the prior art by a number of ways such as through the use of a wire being routed through the structure of the block, through metal contact embedded in LEGO style blocks, or even through the use of conductive paint over LEGO style blocks. These solutions have the same coupling shortcomings as LEGO style blocks and other blocks described above, but also in cases, such as the use of conductive paint, the block lacks the ability to separate electrical signals at each terminal and run multiple currents.
[0009] The present invention seeks to improve upon the current designs of building blocks, while also addressing some of the more common issues in the field relating to structural integrity, modular assembly, and output functionality. Specifically, the invention provides a platform offering increased stability, connectivity, and ease of use, which allows robust assembly and combinations of conductive magnetic blocks capable of powering electronic circuits.
Summary of the Invention
[0010] In view of the above, a system of conductive magnetic blocks, capable of conducting an electrical current through magnetic terminals to additional blocks or electrical devices is provided.
[0011] The advantage of the present invention is that it allows for the production of complex structures without sacrificing stability or modularity. A user may build a structure with the ease of a typical magnetic block simply by aligning terminals of the building blocks having opposing magnetic polarities. When the terminals are coupled in alignment, an electrical current may be conducted from one block to the next. Each block may be a stand-alone unit configured to conduct current or a particular block may comprise an electrical device to be powered by the current, or a combination of the two.
[0012] In a first embodiment, the invention comprises a system of electrically and magnetically conductive building blocks. Each building block comprises a conductive framework disposed within a building block housing. The conductive framework comprises a structural element having magnetic terminals. The conductive framework may be disposed within the block housing such that each magnetic terminal faces a surface of the building block housing. For
connectivity sake it is optimal, but not required, for each block to have a magnetic terminal on at least two surfaces and for conductivity sake, it is optimal, but not required, for each block to have at least two isolated conductive framework units configured for opposite electrical polarities.
[0013] In some embodiments, each conductive frame unit comprises a bar magnet having opposite magnetic polarities on each end acting as coupling and conduction terminals or a structural element having magnetic ends or magnets with similar or opposite magnetic polarities disposed on each end acting as terminals. Each conductive frame unit may be isolated within the block housing to provide separate current paths, or a plurality of conductive framework units may be coupled to form a single current path that may be conducted through any coupled conductive frame unit.
[0014] In additional embodiments, providing additional structural stability within the building block housing, a first conductive framework unit comprising two elongated members having magnets disposed on each terminal end of the elongated members (or two bar magnets) coupled by a conductive corner coupling member and a second conductive framework unit may comprising two elongated members having magnets disposed on each terminal end of the elongated members (or two bar magnets) coupled by a conductive corner coupling member, are disposed within the building block housing such that the elongated members of the first conductive framework unit align to opposite non- adjacent corners of the housing and that the elongated members of the second conductive framework unit align to separate opposite non- adjacent corners. In this embodiment the corner coupling members of the first conductive framework unit and the second conductive framework unit are disposed at different vertical heights of the elongated members such that the first conductive framework unit and the second conductive framework unit remain electrically isolated.
[0015] In yet another embodiment, a first conductive framework unit comprising three elongated members having magnets disposed on each terminal end of the elongated members (or three bar magnets) coupled by two conductive corner coupling members in a corner-side-corner configuration and a second conductive framework unit may comprising three elongated members having magnets disposed on each terminal end of the elongated members (or three bar magnets) coupled by two conductive corner coupling members in a corner-side-corner configuration, are disposed within the building block housing such that the elongated members of the first
conductive framework unit align to a first corner, an opposite non-adjacent side, and an adjacent corner of the housing and that the elongated members of the second conductive framework unit align to separate second corner, a separate opposite non-adjacent wall, and a separate adjacent corner. In this embodiment the corner coupling members of the first conductive framework unit and the second conductive framework unit are disposed at different vertical heights of the elongated members such that the first conductive framework unit and the second conductive framework unit remain electrically isolated.
[0016] In yet another embodiment, a first conductive framework unit comprising at least four elongated members having magnets disposed on each terminal end of the elongated members (or four bar magnets) coupled by two conductive corner coupling members and at least one conductive side coupling member in a corner-side-(side+n)-corner configuration and a second conductive framework unit comprising at least four elongated members having magnets disposed on each terminal end of the elongated members (or four bar magnets) coupled by two conductive corner coupling members and a conductive side coupling member in a corner-side-(side+n)- corner configuration, are disposed within the building block housing such that the elongated members of the first conductive framework unit align to a first corner, an opposite non-adjacent side, and an adjacent corner of the housing and that the elongated members of the second conductive framework unit align to a separate second corner, a separate opposite non-adjacent wall, and a separate adjacent corner. In this embodiment the corner coupling members of the first conductive framework unit and the second conductive framework unit are disposed at different vertical heights of the elongated members such that the first conductive framework unit and the second conductive framework unit remain electrically isolated.
[0017] In another aspect of the invention, each elongated unit in any of the embodiments described above may comprise top and bottom terminal magnets configured to be conductive on the top and bottom surfaces of the building block housing, and side terminals disposed between the top and bottom terminals configured to be conductive on the side surfaces of the building block housing.
[0018] In yet another aspect of the invention, an electrical component may be coupled to the first conductive framework unit and the second conductive framework unit bridging the circuit and powering the electrical component. The electrical component includes by way of non-limiting example LEDs, speakers, displays, RF radios, motors, switches, resistors, capacitors, diodes,
inductors, or integrated circuit chips. In any of the embodiments discussed above, the system's output will be dictated by the number, type(s), and shape(s) of the functional components that are electrically activated and coupled to the block's terminal elements. The function of these components can include alternate functionality, including circuit isolation, or non-functionality.
[0019] In one aspect of the invention, the conductive framework units are insert-molded into plastic building block housing.
[0020] In another aspect of the invention, the conductive framework units are pressed and held via a compression fit or adhesive into an already shaped plastic, wood, or other suitable non- conductive housing material building block housing.
[0021] In yet another aspect of the invention, the terminals may be exposed through the housing such that each building block unit connects directly to each stacked building block through a direct terminal connection.
[0022] In yet another aspect of the invention, the terminals may be covered housing such that each building block unit connects through induction indirectly to each stacked building block.
