Toy blocks

Abstract

The present invention generally relates to toy blocks, and more specifically, to toy blocks into which other blocks can be easily inserted on sides of each configured block. The present invention suggests toy blocks including hexahedral blocks where convex projections are formed on at least one side while concave grooves inserted into the convex projections are formed on the remaining side.

1 . Toy blocks including a hexahedral block, comprising: convex projections formed on at least one side; and concave grooves configured to be inserted into convex projections on all of the remaining sides through an interference-fit method.  
   
   
       2 . The toy blocks of  claim 1 , wherein piercing grooves, which pierce through middle parts of one side that constitutes the hexahedral block and an opposite side opposing the one side, are further comprised.  
   
   
       3 . The toy blocks of  claim 1 , wherein 4 convex projections are disposed on sides where the convex projections are formed.  
   
   
       4 . The toy blocks of  claim 2 , wherein 4 convex projections are disposed on sides where the convex projections are formed, and 4 concave grooves are disposed on each side where the concave grooves are formed.  
   
   
       5 . The toy blocks of  claim 4 , wherein concave spaces are made among neighboring convex projections.  
   
   
       6 . The toy blocks of  claim 1  or  2 , wherein the convex projections are equipped with vertical grooves passing through central parts, so that upper sides of the convex projections are divided into more than two parts.  
   
   
       7 . The toy blocks of  claim 2 , wherein the convex projections are equipped with vertical grooves passing through central parts, so that upper sides of the convex projections are divided into more than two parts.  
   
   
       8 . The toy blocks of  claim 1 , wherein a connection piece equipped with insertion projections inserted into the piercing grooves on both ends, as forming a flat and long plate shape, is further comprised.  
   
   
       9 . Toy blocks including a cylindrical block comprising a plane-shaped upper side, a bottom side, and sides, comprising: convex projections formed on the upper side; concave grooves configured to be inserted into convex projections on the bottom side through an interference-fit method; and vertical piercing grooves piercing through the middle of the upper side and the bottom side, first horizontal piercing grooves piercing through central parts of the sides, and second horizontal piercing grooves piercing through the central parts of the sides as being vertical to the first horizontal piercing grooves.  
   
   
       10 . The toy blocks of  claim 9 , wherein a connection piece equipped with insertion projections inserted into the piercing grooves on both ends, as forming a flat and long plate shape, is further comprised.
