## Background
BACKGROUND OF THE INVENTION
The present invention relates to an assembling toy block with embedded magnets that is assembled into a regular hexahedral frame and has magnetic balls, such as ball bearings, embedded in edges of upper and lower frames of the block such that the magnets embedded in the edges can overcome polarity between the magnets, which is generated when the blocks are assembled, by rotation, that allows a user to see movements of the magnetic balls, and that helps to develop children's creativity and intelligence while children accumulate, assemble and disassemble three-dimensional building blocks in various ways.
There are many assembling toy building blocks, for instance, Korean Patent No. 10-0430854 discloses a prefabricate toy block set, Korean Patent No. 10-0457305 discloses a rotational magnet joining device and an assembling toy having the same, Korean Patent No. 10-0496129 discloses an assembling toy blocks, Korean Utility Model Registration No. 20-375134 discloses a block set with magnets, and Korean Utility Model Registration No. 20-0265633 discloses an assembling teaching tool for infants.
The above prior arts will be described in more detail. First, the assembling toy block set disclosed in Korean Patent No. 10-0430854 includes a concavo-convex structure mounted on opposed and facing surfaces, a plurality of unit blocks separably assembled by gravitation of magnets with opposite polarity, a plurality of block links and block wheels. The assembling toy block set enables infants or children to enjoy playing with blocks because the blocks provide good joining force. Second, assembling toy blocks disclosed in Korean Patent No. 10-0496129 includes a plurality of parts of polyhedral shapes having joining faces in such a way as to be joined with joining faces of other parts. The parts respectively have magnetic portions formed on the joining faces, so that the block is assembly by magnetic force between the magnetic portion of the part and the magnetic portion of other part, and in this instance, a plurality of magnets are inserted and fixed on each face of the polyhedron.
Third, the rotational magnet joining device and the assembling toy having the same disclosed in Korean Patent No. 10-0457305 have 85 claims, but the assembling toy is similar in structure with the above-mentioned assembling toys, but there is a greater or less difference in that the magnets are formed in a ball bearing shape.
Fourth, the block set with magnets disclosed in Korean Utility Model Registration No. 20-375134 includes a magnet mounted at an area and a block unit of a ring shape with a predetermined width.
Fifth, the assembling teaching tool for infants disclosed in Korean Utility Model Registration No. 20-0265633 includes a plurality of separable bodies divided equally from a completed body, which has a predetermined width and size, at a fixed percentage, and joining means mounted at a predetermined position on an outer face of the separable bodies in order to keep a mutually fixed condition when the separable bodies are joined together. In order to develop intellectual curiosity and intelligence while infants or children join the separable bodies divided equally at the fixed percentage, magnets are inserted and mounted on faces of the hexahedral body. The toy blocks according to the prior arts are all formed by the magnets fixed or inserted on each face of the body like a dice. In all of toys or teaching materials till now, the magnets are fixed, inserted or embedded at fixed positions not to be seen from the outside, and the shapes of the blocks are formed by the magnet's magnetic force
SUMMARY OF THE INVENTION
Differently from various toys or teaching tools according to the prior arts, the present invention provides an assembling toy block with embedded magnets that includes an upper frame, a lower frame and four pillars which are assembled into a regular hexahedral block, eight spherical magnets of a ball bearing shape inserted into each edge of the upper and lower frames in such a fashion that assembled blocks are joined together in a wanted shape by the spherical magnets of various three-dimensional shapes in order to overcome polarity between the magnets generated when the blocks are joined together. Moreover, a user can see a rolling flow of the spherical magnet by polarity while the spherical magnets of the upper and lower frames and the pillars all have inward-facing protrusions which are inserted into insertion apertures formed in the small rails and curved rails. Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide an assembling toy block with embedded magnets, which enables the user to assemble and accumulate the blocks in various shapes and forms and helps to develop infants' and children's intelligence and creativity.
To achieve the above objects, the present invention provides an assembling toy block with embedded magnets that includes: hexahedral upper frame and lower frame; insertion apertures formed at four edges of the inner faces of the upper and lower frames; and hollow portions respectively formed below the insertion apertures. Magnetic balls (spherical magnets) are respectively inserted into the hollow portions in such a way as to be freely moved; and protrusions projectingly formed on upper and lower ends of four pillars and respectively inserted and assembled into the insertion apertures of the upper and lower frames, so that a regular hexahedral block is completed.
Here, when the protrusions formed at the upper and lower ends of the pillars are inserted into the insertion apertures of the upper and lower frames, the pillars get in close contact with the upper and lower frames without falling out. If the joining state is in an incomplete state, adhesives may be used to firmly bond them. When the protrusions are inserted into the insertion apertures, the spherical magnets inserted into the hollow portions are freely movable, and is not interrupted in movement.
Moreover, the blocks according to the present invention are blocks of three types that include: hexahedral upper and lower frames and pillars respectively having a plurality of inward-facing protrusions; and small rails, curved rails and straight rails formed on a rail and respectively having insertion grooves which are formed at both ends of the outer face thereof and are firmly fit onto the protrusions. When the blocks are accumulated or joined with one another, the user can observe and see that the magnetic balls are rotated while moving according to their polarities. Furthermore, the user can enjoy playing with the block while observing a rolling state of the spherical balls or the magnetic balls inside the rails when the user properly assembles and connects the three types of the blocks to which the straight rails and the curved rails are assembled and inserts the spherical balls or the magnetic balls into the blocks.
Because the block according to the present invention having the regular hexahedral shape is joined to other block in such a fashion that the polarities of the magnetic balls are meet to attract mutually, when the blocks are joined together, the magnetic balls are freely rotated inside the hollow portions in such a fashion that the polarities of the magnetic balls are meet to attract mutually. Especially, the user can observe that the magnets embedded in the blocks are rolled by connecting and assembling the blocks having the small rails, the curved rails and the straight rails, whereby, the present invention can help to develop children's intelligence and creativity.
