SURFACE STRUCTURE FOR COMBINING BLOCK OF BLOCK TOY HAVING MAGNET INSIDE

摘要

The present invention relates to a surface structure, on which protuberances and slots are configured so that the protuberances interlock organically with the slots to secure stable combination between the blocks of a block toy when the blocks are stacked up, combined laterally or combined at right angles to each other.

1. A surface structure for combining blocks, with a magnet internally embedded, of a block toy on a block that comprises a top frame and a bottom frame that are combined by fitting protuberances and fitting slots resulting in a quadrate panel with a hollow at the center,
wherein a magnet holder is prepared at the internal center of each of the four sides of the top frame and the bottom frame to hold a cylindrical magnet, that lies parallel to the side, in the internal space of the magnet holder so that the magnet may rotate; on the external surface of the top frame and the external surface of the bottom frame, between the fitting protuberance and the fitting slot with a predetermined distance, with the center of each side as the center, a plurality of left horizontal protuberances are spread to the left while right horizontal protuberance(s) are spread to the right, the number of which is one less than the number of the left horizontal protuberances, parallel to and along the side with a certain distance from the edge of the side; a top slope is configured along the edge of the top frame and, from the top slope, a top cliff extends downward while a bottom slope is configured along the bottom frame, and from the bottom slope, a bottom cliff extends upward; on the top slope, with the center of each side as the center with a predetermined distance from the center, a plurality of grooves are spread to the left and tongues as many as the grooves are spread to the right while, on the bottom slope, with the center of each side as the center with a predetermined distance from the center, tongues as many as the grooves on the top slope are spread to the left and grooves as many as the tongues on the top slope are spread to the right; and in the top cliff, with the center of each side as the center with a predetermined distance from the center, a furrow is grooved on the left and an insert protrudes on the right while, in the bottom cliff, with the center of each side as the center with a predetermined distance from the center, an insert protrudes on the left and a furrow is grooved on the right.
