Abstract
A magnetic toy construction piece and set for building lattice structures is disclosed. Magnetic pieces are rod-shaped and have magnets on their long faces. Magnets are color-coded depending on their polarity. Platform pieces for support and offset pieces are also contemplated.
Description
- Not applicable.
- The field of the invention is toy construction sets. In particular, the invention relates to toy construction sets utilizing rods and magnets.
- Not applicable.
- Not applicable.
- Children and adults enjoy building structures from basic building blocks. The LEGO™ and DUPLO™ are examples of popular construction toy building devices. These and standard blocks, however, do not utilize magnets to join blocks together.
- Magnets provide an interesting and educational means of joining materials together. Magnets can be used to join building blocks together to create three-dimensional structures. Because magnetic attraction is intriguing and powerful, it is desirable to use magnets to facilitate construction. In addition, because magnetic attraction operates differently than mechanical joints, new and different structures can be built.
- The prior art discloses building blocks with magnets that can be stacked. However, the prior art does not disclose rods and beams that can build a lattice structure. U.S. Pat. No. 5,009,625 to Longuet-Higgins describes a magnetic block shaped as a rhombohedron. U.S. Pat. No. 5,746,638 to Shiraishi describes a cubic block with rotatable bipolar magnets on the faces. U.S. Pat. No. 6,024,626 to Mendelsohn describes a magnetic block with bar magnets placed in parallel along four faces of a cube or rectangle, and magnets centered on a face. United States Patent Application Publication 2007/0037469 of Yoon describes a block with movable magnets for stacking blocks. These inventions all use blocks, such as cubes or rhombohedra, for construction. For a given height, width or length of a structure, a block will require more building material, which in turn necessitates more weight and construction pieces, which will limit the size a structure can achieve. In addition, the heavier structure requires stronger magnets to hold itself together. Stronger magnets are more expensive, and thus this drives up the cost of the toy construction set. Blocks also do not allow for the building of aesthetically pleasing lattice structures, which can be seen through.
- In addition, the prior art discloses planar toy pieces that can be joined together using magnets to create a three-dimensional structure. But, again, these planar toy pieces are not capable of building aesthetically pleasing lattice structures. U.S. Pat. No. 5,021,021 to Ballard describes a flat square-shaped block set with rounded corners that can be joined together to build structures. U.S. Pat. No. 5,545,070 to Liu describes another planar block with apertures and connectors for building. U.S. Pat. No. 6,017,220 to Snelson also discloses a magnetic toy with flat pieces that are joined together to form structures. U.S. Pat. No. 7,255,624 to Daftari discloses a building set with planar panels and embedded magnets. Similar to block pieces, planar toy pieces consume more material for a given structure size. In addition, these planar toy pieces do not allow building of an aesthetically-pleasing lattice structure.
- There are recent patents to magnetic construction sets that use rod-shaped pieces, but these sets require connectors for three-dimensional building. Furthermore, these art do not use two-dimensional cross-sections (triangular, rectangular, etc.) to facilitate novel and interesting building patterns. U.S. Pat. No. 6,566,992 to Vicentelli shows a magnetic construction set with cubic and spherical connector pieces. Similarly, U.S. Pat. No. 6,626,727 to Balanchi, U.S. Pat. No. 6,846,216 to Balanchi, U.S. Pat. No. 6,969,294 to Vicentelli, and U.S. Pat. No. 7,234,986 to Kowalski disclose magnetic construction toys using spherical connectors. Connector pieces are undesirable for several reasons. First, they are small and can be swallowed or choked upon, which is a safety hazard for small children. Second, they are additional pieces that can be lost, and once they are lost, the set becomes useless. Third, as an additional piece, a construction set is more expensive to manufacture with these extra pieces. To eliminate these drawbacks, it is desirable to invent a magnetic construction set capable of building lattice structures that does not require connectors.
- One goal of the present invention is to provide a magnetic toy building set that can build lattice structures. Another goal of the present invention is to be able to build in all three dimensions without the use of connectors. Another goal of the present invention is to provide a stable platform so that a lattice can reach high off the ground. Another goal of the present invention is to allow construction where rods are connected on their long faces, not just their ends. Yet another goal is to provide an invention that will assist children and adults in understanding magnetic fields. Another goal of the invention is to be easy to work with, so that children of young ages and adults with limited motor facility can use the invention.
- The present invention is directed to a building set using three-dimensional rod-shaped pieces with magnets attached to the long faces of the rods. Magnets may also be attached to the ends of the rods. Magnets that are attached may be embedded in the face, or be stuck to the surface, or partially embedded.
- The rods have a polygonal cross-section (e.g., triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, dodecagonal, etc.), and magnets are placed on the long faces of the rods. Magnets may also be placed at the ends of each rod. Different pieces can be held together when a magnet of one polarity on one piece aligns with a magnet of opposite polarity on another piece.
- One or more platform pieces can also be used to support the structure. A platform may have a substantially flat shape for stability. The platform may have magnets embedded on it to connect to a rod.

FIG. 1 illustrates a rectangular rod in one embodiment of the invention.FIG. 1 a shows arod 20. One long face has two magnets, onemagnet 22 near one end of the rod, and asecond magnet 24 near the opposite end of the rod. The long face magnets are spaced one unit apart. One unit can be 1-36 inches in length; the inventor has built a prototype with a unit of approximately 5⅝-inch. -
FIG. 1 b shows another embodiment of arod 30. One long face of this rod has three magnets, amagnet 32 near one end of the rod, amagnet 34 near the opposite end of the rod, and amagnet 36 near the middle of the rod. Each long face magnet is spaced one unit apart. -
FIG. 1 c shows another embodiment of arod 40. One long face of this rod has four magnets, amagnet 42 near one end of the rod, amagnet 44 near the opposite end of the rod, and twomagnets 46 equally spaced between the other magnets. - In
FIGS. 1 a-c, the spacing between magnets on a long side is the same for each rod shown. Each rod is rectangular in cross-section and may have magnets on all six faces of the rod, or only some of the faces. The length of the rod is much greater than the width or height of a cross-section. Each face has single polarity magnets facing outwards, with all magnets on one face of the rod of the same polarity. The inventor has found that an optimal arrangement of polarities on the long faces is N-N-S-S. This allows every long face to have a neighboring face of North polarity and a neighboring face of South polarity, providing the greatest variety and number of building options. - The polarity of magnets can be indicated by coloring. In one embodiment, the inventor has colored all magnets of one polarity orange, and all colors of the opposite polarity black. A connection is made by aligning an orange magnet with a black magnet. When coloring is used, a magnet may be colored in any possible manner. For example, the magnet may be painted. Or, the magnet may be covered with an adhesive or film or paper or any other covering that has a color. It is understood that other colors can be used to indicate polarity, or polarity could be indicated by texture (such as diagonal lines or checkerboard pattern). Alternative methods of indicating polarity, such as marking “N” or “S” to indicate “North” or “South” polarity are also contemplated.
- A rod may be built of wood or plastic or foam or any appropriate firm material and may be hollow or solid. Magnets on the faces may be embedded or placed on the outside of a rod. Magnets can be held in place mechanically (e.g., in a slot), using adhesive (e.g., glue or cement), or using any other adhering means. It is optional to enclose the magnet area using plastic wrap, lamination or a cover to prevent a magnet from coming loose if the adhering means fails.
- Magnets can be of any type and shape. The inventor used flat cylindrical magnets purchased from a nearby supply shop. The strength of magnetic connections should be strong enough to hold the structure together, but weak enough that children can separate the connection.

FIG. 2 illustrates astructure 50 built from rectangular rods under one embodiment of the invention. The alignment of opposite polarity magnets in the rods is sufficient to hold the structure together, without connectors. In addition, a rod or multiple rods can be placed on the floor to brace the structure, or rods can be placed vertically from the floor. -
FIG. 3 a illustrates aplatform 60 in one embodiment of the invention. The platform is flat with an X-shape, with magnets at the center of each X. One face of the platform has a North-polarity magnet 64 facing outward on aflat surface 62. The opposite face of the platform has a South-polarity magnet facing outward from its flat surface. This way the platform can be turned over to accommodate an opposite-polarity connection point. -
FIG. 3 b illustrates aplatform 70 that only provides a mechanical stability. The X-shape is the same, but the rod fits into arecess 72 at the center of the X for stability. -
FIG. 3 c illustrates aplatform 80 that is cube-shaped and has recesses into which rods can be placed. Thevertical recess 82 allows for emplacement of a rod emanating vertically from the platform. It is readily understood thatFIG. 3 c can be used to connect rods, in addition to providing a stable platform placed on the ground. - The invention is not limited to rectangular rods.
FIG. 4 a illustrates atriangular rod 100. The rod shown has an equilateral triangle cross-section, which allows for building at 60 degrees and 120 degrees from other dimensions.FIG. 4 b illustrates an isosceles right triangular rod 110. Its cross-section allows for building at 45 and 135 degree angles. -
FIG. 5 illustrates anoctagonal rod 120. For non-rectangular cross-sectional rods, the arrangement of magnets on a face can follow a NNSS . . . NNSS . . . pattern or any other pattern desired. A triangular cross-section piece only has three long faces, so the options are NNN, NNS, NSS, and SSS for polarities on the long faces. - In addition, in one embodiment, magnets at some locations are replaced with magnetizable metal. The substitution of magnetizable metal allows that location to be attracted by any polarity magnet, and reduces construction cost. Magnetizable metal could replace all magnets on one face of a rod, or only some magnets on a face of a rod.
FIG. 10 illustrates different arrangements of magnets of different polarities and magnetizable metal on faces of a rod with three magnets on a face. - A toy building set can include only one type of cross-section rod (e.g., all triangular or all rectangular) or it may include different cross-sections, such as rectangular and triangular, rectangular and octagonal, rectangular and octagonal and triangular, etc.
- In a rectangular embodiment, the spacing of magnets is equal on all long faces of the invention. Equal spacing can be used in any other cross-sectional rod set, or in a set mixing rods of different cross-sections.
- In addition, the spacing can be adjusted to align magnets for different building approaches.
FIG. 6 illustrates astructure 130 constructed from rectangular rods with different spacing.Horizontal rod 134 andvertical rods 136 have equal spacing between long-face magnets.Diagonal rods 132 have spacing of SQRT(2) times the long-face spacing. This allows the diagonal rod to align with magnets on the horizontal rods. -

A cubic offset may be used to add connection strength at a nexus, or it may provide a new place to build, adjacent to a nexus. The offset's sides may have amagnet 142 which can attract to a rod.FIG. 7 b shows an exploded view of a cubic offset. Offsets of different shapes may be used. It may be desirable to match the offset shape with the rod shape. For example, a triangular rod fits well with a pyramidal offset. The offset shown has monopolar (one polarity facing outward) magnets on each face; in one alternative embodiment, the offset has magnetizable metal (metal capable of being attracted by a magnet) on one or more faces. -

For example, magnets do not have to be monopolar on a face. They could be bipolar and they could also be allowed to rotate into alignment.
- In addition, magnets could be removable, such as by slipping into a slot. This would allow magnets to be manipulated by the user to make rods, platforms, and offsets attract.
- The set is packaged in a box which has different sections for housing the different types of pieces. The box has compartments shaped specifically to match the piece types—there is a section for rods, a section for offsets, and a section for platforms.
FIG. 13 a shows thebox 230 in one embodiment of the invention. There are slots for packingrods 232, slots for packingplatforms 234, and slots for packingoffsets 236. Alternatively, the set can be sold without offsets, and a box designed accordingly.FIG. 13 b shows one embodiment of such abox 240. There are slots for packingrods 242, and slots for packingplatforms 244. - The box can also come with directions describing how to build interesting structures.
-
FIG. 14 a shows adisplacement rod 250 in one embodiment of the invention.Magnets 252 are near the ends of a long face. In addition,magnetizable metal 254 is attached one cross-section of a rod away from themagnets 252. As shown inFIG. 14 b, by placing magnetizable metal in this manner, astructure 260 can be constructed easily without use of offsets. Themagnetizable metal 254 could also be a magnet and accomplish a similar result. A set can be created using only displacement rods with magnets or magnetizable metal one cross-section away from end magnets, or by combining displacement rods and rods without the magnets or magnetizable metal attached one cross-section of a rod away from end magnets. -
FIG. 15 a shows another embodiment of a rod under the invention. In this embodiment,magnets end magnet 272 and itsnearest magnet 274 is equal to the distance between anotherend magnet 278 and itsnearest magnet 276.FIG. 15 b illustrates a structure built using a mixture of rods with two magnets attached approximately midway and rods that do not have two magnets attached approximately midway. - It is to be understood that other embodiments may be utilized and structural and functional changes may be made without departing from the scope of the present invention. The foregoing descriptions of embodiments of the invention have been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Accordingly, many modifications and variations are possible in light of the above teachings.
