The block 1, with a length or width ranging from 60 to 70 mm and a thickness ranging from 6 to 9 mm, comprising the top frame 11 and the bottom frame 12, may be required to assume the shape of a quadrate panel with a hollow at the center because, if the length or width is less than 65 mm and the thickness is less than 6 mm the block becomes excessively small as a block for a block toy, whereas if the length or width is more than 70 mm and the thickness is more than 9 mm the block becomes excessively large as a block for a block toy. A block 1 comprising the top frame 11 and the bottom frame 12 as provided by Embodiment of the present invention has a length or width of 65 mm and a thickness of 7 mm, and assumes the shape of a quadrate with a hollow at the center while each or the four sides of the block has a width of 11 mm. On the external surface of the top frame 11 and the external surface of the bottom frame 12,horizontal protuberances 21, 21-1 are arrayed parallel to and along the side with a certain distance from the edge of the side. Thehorizontal protuberances 21, 21-1 may be required to have a height ranging from 0.25 to 0.35 mm because, if thehorizontal protuberances 21, 21-1 have a height that is less than 0.25 mm, engaging becomes too weak to retain the combination between the horizontal protuberances of the top frame 11 and the bottom frame 12 whereas, if thehorizontal protuberances 21, 21-1 have a height that is more than 0.35 mm, such a protrusion causes inconvenience to use.

grooves 26 are spread to the left and three steps of tongues 27 are spread to the right while, on the bottom slope 24, with the center of each side as the center, with a predetermined distance in between, three steps of tongues 27 are spread to the left and three steps ofgrooves 26 are spread to the right. It may be required for thegrooves 26 and the tongues 27 to have a depth and a height, respectively, ranging from 0.25 to 0.35 mm because if the depth and the height, respectively, are less than 0.25 mm, engaging becomes too weak to retain the combination between, for example, the tongues 27 of the top slope 22 and thegrooves 26 of the bottom slope 24 whereas, if the depth and the height, respectively, are more than 0.35 mm, such a protrusion causes inconvenience to use. In this Embodiment, the depth of each of thegrooves 26 and the height of each of the tongues 27 is 0.3 mm. - In the top cliff 23, with the center of each side as the center with a predetermined distance from the center, a
furrow 28 is grooved on the left and an insert 29 protrudes on the right while, in the bottom cliff 25, with the center of each side as the center with a predetermined distance from the center, an insert 29 protrudes on the left and afurrow 28 is grooved on the right. It may be required for thefurrow 28 and the insert 29 to have a height ranging from 0.4 to 0.6 mm because the height of thefurrow 28 and the insert 29 is less than 0.4 mm, engaging becomes too weak to retain the combination between, for example, the furrow 20 of the top cliff 23 and the insert 29 of the bottom cliff 25 whereas, if the height of thefurrow 28 and the insert 29 is more than 0.6 mm, such a protrusion causes inconvenience to use. In this Embodiment, thefurrow 28 and the insert 29 have a height of 0.5 mm. - Such a configuration is identically applied to all the four sides and edges of the block 1, which assumes the shape of a quadrate panel, of the present invention.

horizontal protuberances 21, 21-1 of the upper block 2 interlock with thehorizontal protuberances 21, 21-1 of the lower block 3. In other words, for example, as illustrated inFIG. 5 , the two horizontal protuberances 21-1 that are spread to the left of the upper block 2 interlock with the threehorizontal protuberances 21 that are spread to the left of the lower block 3 so that the two blocks 2, 3 thus stacked up maintain stable vertical binding even if one applies lateral force onto each block in the opposite direction to each other. -
FIG. 6 illustrates a status of blocks that are to be combined laterally according to the present invention andFIG. 7 is a cross-sectional view of blocks combined laterally according to the present invention. On the top cliff 23 in the posterior edge 4-1 of an anterior block 4, with the center of the side as the center, with a predetermined distance in between, an insert 29 protrudes on the left and a furrow 29 is grooved on the right while, on the bottom cliff, with the center of the side as the center, with a predetermined distance in between, aninsert 28 protrudes on the left and a furrow 29 is groove on the right.

insert 28 and the furrow 29 of the posterior edge 4-1 of the anterior block 4 and the anterior edge 5-1 of the posterior block 5, respectively, interlock with each other so that the two blocks 4, 5 thus combined laterally maintain stable lateral binding even if one applies vertical force onto each block in the opposite direction to each other -
FIG. 8 illustrates a status of blocks that are to be combined at right angles according to the present invention andFIG. 9 is a cross-sectional view of blocks combined at right angles according to the present invention. On the bottom slope 24 in the anterior edge 6-1 of a lateral block 6, with the center of the side as the center, with a predetermined distance in between, three steps of tongues 27 are spread to the left and three steps ofgrooves 26 are spread to the right while, on the bottom slope 24 in the upper edge 7-1 of a vertical block 7, with the center of the side as the center, with a predetermined distance in between, three steps ofgrooves 26 are spread to the left and three steps of tongues 27 are spread to the right. - The bottom slope 24 is inclined at an angle of 45° so that the lateral block 6 and the vertical block 7 are combined at an angle of 90° in between or at right angles to each other. If the lateral block 6 and the vertical block 7 are combined at right angles, the
grooves 26 interlock with the tongues 27 to secure stable binding at right angles to each other. - Maximum compression load was measured on regular hexahedrons configured by the blocks 1 the present invention provides in order to scientifically verify the strength that maintain the vertical binding.
- Block toys, with magnets internally embedded, manufactured by Magformers and currently marketed were used in Comparative Example. A
block 8 of the Magformers block toy assumes, as illustrated inFIG. 1 , the shape of a quadrate panel with a hollow at the center and acylindrical magnet 16 is embedded at the internal center of each of four sides of theblock 8 so that the magnet may rotate. - The
block 8 has a length or width of 65 mm and a thickness of 7 mm, assumes the shape of a quadrate panel. - Each of the four sides has a width of 11 mm and the tip of the edge of the block is rounded.
- Two of the
blocks 8 were stacked up, combined laterally or combined at right angles according to the method applied to Embodiment. Because the tip of the edge of the blocks were rounded, the twoblocks 8 thus stacked up were broken down with ease when lateral force was applied onto each of the blocks in the opposite direction to each other, and the twoblocks 8 thus combined laterally were broken down with ease when rotational force was applied onto each of the blocks in the opposite direction to each other. - The two
blocks 8 thus combined at right angles were broken down with ease under a slight impact. Maximum compression load was measured on regular hexahedrons configured by theblocks 8 in order to scientifically verify the strength that maintain the vertical binding. - Compression tests were implemented on regular hexahedrons configured by the
blocks 8, the edge tips of which were rounded, manufactured by Magformers and the blocks 1 provided by the present invention, respectively. - A vertical compression load at a velocity of 5 mm/min was applied onto the regular hexahedrons mounted in a material testing machine to obtain maximum compression load values. Related Certificates of Analysis were issued on Jul. 25, 2014 by the Korea Testing Laboratory.
- According to the Certificates of Analysis, the maximum compression load was 20 N for the regular hexahedron configured by the
blocks 8 manufactured by Magformers and 87 N for the blocks 1 provided by the present invention, which indicates a significant increase of the maximum compression load by 335% in the blocks 1 provided by the present invention compared to theblocks 8 manufactured by Magformers. - Embodiment of the present invention provides a quadrate block 1 but the shape of the block must not be limited thereto but may include a variety of shapes such as rectangle, triangle, hexagon, octagon, etc.
