Definitions

  • the present disclosure relates to a surface structure for connecting a block of a block toy that has a magnet embedded inside, and more particularly, to a block toy that has a magnet embedded inside and a surface structure for connecting a block thereof, wherein overhang-like structures and hollow-like structures are formed on the block surface of the block toy that has a magnet embedded inside so that the overhang-like structures on each block surface interlock organically with the hollow-like structures on each block surface in order to secure stable assembly between the blocks of a block toy when the blocks are stacked up or interlocking at right angles or laterally with each other, thereby, especially, preventing the block thus interlocked from slipping out of the assembly with the external force that is exerted in a direction other than the direction the block interlocks in when it is stacked up or interlocking at right angles or laterally with each other.
  • a block toy includes a plurality of and a set of small blocks that are typically made of plastic so that the blocks are to be assembled to construct a solid shape.
  • Self-assembly toys as a kind of block toys, have been marketed for which it is required to interlock the protuberances and slots configured in each block to complete the toy.
  • As for such an self-assembly toy it is, however, also required to forcefully plug each protuberance into each slot corresponding to the protuberance in each block and, even after the assembly is completed, it is not very easy to disassemble the blocks to construct another solid shape.
  • Those block toys have also been marketed that include blocks with magnets embedded inside so that the blocks are easily assembled by means of magnetism when brought proximately to each other.
  • a block toy with magnets although it is convenient to assemble the blocks with each other by means of magnetism and also convenient to disassemble after the assembly is completed, the form may collapse with a rather slight impact because, in most cases, the edges of the blocks are rounded and, correspondingly, the binding between the blocks is not firm.
  • the applicant of the present disclosure provided Korean Utility Model Registration No. 20-0475198, SURFACE STRUCTURE FOR THE CONNECTION BETWEEN BLOCKS EQUIPPED WITH MAGNET OF BLOCK TOYS.
  • the utility model provides significantly firm binding between the blocks although the edges of the blocks are rounded, thereby considerably increases the normal maximum compressive load.
  • it shows a drawback in that the block thus assembled slips out of the assembly with the external force that is exerted in a direction other than the direction the block interlocks in when it is stacked up or interlocking at right angles or laterally with each other.
  • the applicant has continued to study a surface structure that may bind the blocks together more stably and hereby provides a surface structure that may bind the blocks together stably preventing the block from slipping out of the block assembly with the external force that is exerted in any direction even including the direction the block interlocks in.
  • the present disclosure is directed to a block toy that has a magnet embedded inside and a surface structure for connecting a block thereof, wherein overhang-like structures and hollow-like structures are formed on the block surface of the block toy that has a magnet embedded inside so that the overhang-like structures on each block surface interlock organically with the hollow-like structures on each block surface in order to secure stable assembly between the blocks of a block toy when the blocks are stacked up or interlocking at right angles or laterally with each other, thereby, especially, preventing the block thus interlocked from slipping out of the assembly with the external force that is exerted in a direction other than the direction the block interlocks in when it is stacked up or interlocking at right angles or laterally with each other.
  • a surface structure for the connection between blocks equipped with magnet of block toys includes a block of a block toy as a single assembly, into which a top frame and a bottom frame are integrated, that assumes the shape of a quadrate panel with an opening at the center and has, inside and at the center of each of the four sides of the top frame and the bottom frame, a magnet holder with an internal space for magnet rotation into which a single cylindrical magnet or two cylindrical magnets in tandem are placed in the longitudinal direction of the edge of the top frame and the bottom frame, respectively, wherein a lateral protuberance and a fitting slot are alternately arranged with a certain distance in between on a top plane of the top frame and a bottom plane of the bottom frame in the longitudinal direction of the edge of the top plane and the bottom plane so that, when another block is laid down on the top plane of the top frame of the block, the lateral protuberance of the top plane of the top frame of the underlying block is plugged into the fitting slot of the bottom plane of the bottom frame of the overlying block
  • the block into which the top frame and the bottom frame are integrated has a width and height of 60 to 70 mm and a thickness of 6 to 9 mm.
  • the lateral protuberance and the fitting slot has an identical depth of 0.8 to 1.0 mm.
  • the grooves on the top and bottom inclined planes have a depth of, and the tongues formed thereon have a height of 0.25 to 0.35 mm.
  • the grooves on the top and bottom vertical planes have a depth of, and the tongues formed thereon have a height of 0.4 to 0.6 mm.
  • the bumps and the depressions have a height and depth, respectively, of 0.8 to 1.0 mm.
  • a block toy that has a magnet embedded inside and a surface structure for connecting a block thereof according to the present disclosure has overhang-like structures and hollow-like structures on the surface of each of the blocks so that the structures organically interlock with each other when the blocks are stacked up or interlocking at right angles or laterally with each other, thereby being capable of stably binding the blocks together.
  • the present disclosure may prevent the block thus interlocked from slipping out of the assembly with the external force that is exerted in a direction other than the direction the block interlocks in when it is stacked up or interlocking at right angles or laterally with each other.
  • FIG. 1 is a perspective view of a magnet block on which a surface structure is configured according to the present disclosure.
  • FIG. 2 is a perspective view of magnet blocks stacked up according to the present disclosure.
  • FIG. 3 is a perspective view of magnet blocks that interlock with each other at right angles according to the present disclosure.
  • FIG. 4 is a perspective view of magnet blocks that interlock with each other laterally according to the present disclosure.
  • FIG. 5A shows blocks, on which a surface structure is configured according to the related art, that interlock with each other laterally and are pushed in the opposite direction to each other.

  • a block 100 of a block toy according to the present disclosure that has a magnet inside is a single assembly, into which a top frame 10 and a bottom frame 20 are integrated, that assumes the shape of a quadrate panel with an opening at the center and has, inside and at the center of each of the four sides of the top frame 10 and the bottom frame 20 , a magnet holder (not illustrated) with an internal space for magnet rotation into which a single cylindrical magnet or two cylindrical magnets in tandem (not illustrated) are placed in the longitudinal direction of the edge of the top frame 10 and the bottom frame, respectively.
  • the blocks attract each other more strongly than the blocks having a single cylindrical magnet in the magnet holder do because the blocks with two cylindrical magnets have more polarities. It may be required the block 100 into which the top frame 10 and the bottom frame 20 are integrated have a width and height of 60 to 70 mm and a thickness of 6 to 9 mm and assume the shape of a quadrate panel with an opening in the center because a width and height less than 60 and thickness less than 6 mm are not adequate while a width and height more than 70 and thickness more than 9 mm are excessive for a block for a block toy.
  • the block 100 into which the top frame 10 and the bottom frame 20 are integrated has a width and height of 65 mm and thickness of 7 mm and assumes the shape of a quadrate panel that has an opening in the center, with the width of each of the four sides being 11 mm.

  • the lateral protuberance 30 and the fitting slot 31 has an identical depth that ranges between 0.8 to 1.0 mm because the interlocking force may decrease between the lateral protuberance 30 and the fitting slot 31 when the depth is less than 0.8 mm while a depth more than 1.0 mm makes the lateral protuberance 30 protrude excessively high, thereby bringing about inconvenience in using the block.
  • the lateral protuberance 30 and the fitting slot 31 has a depth of 0.9 mm.
