Assembly blocks

Abstract

The present invention relates to assembly blocks which can freely be coupled into various text arrays and creative shapes by means of insert-coupling or slide-coupling of a first block and a second block which can be manufactured from a lightweight material.

1 . Assembly blocks comprising:
 a first block configured to have a shape of a panel and having at least one edge provided with a receiving part;
 a second block configured to have a shape of a panel and having at least one edge to be received in the receiving part of the first block; 
   a first click coupling part configured to protrude or to be recessed on the receiving part; and   a second click coupling part formed at a portion of the second block received in the receiving part and configured to be sliding-coupled or insert-coupled to the first click coupling part.   
     
     
         2 . The assembly blocks of  claim 1 , wherein the receiving part is formed to have a shape of a groove configured such that a central portion of side surface of the edge of the first block is recessed, and the first click coupling part is formed to have a shape of a rib and configured to be spaced apart from an inner end of the receiving part. 
     
     
         3 . The assembly blocks of  claim 1 , wherein in case that the second click coupling part is formed at opposite edges of the second block, the second block is configured such that ends of receiving parts of two neighboring first blocks coupled to the second block come into contact with each other to inhibit the second block from being exposed to outside when the second block is coupled to the two neighboring first blocks. 
     
     
         4 . The assembly blocks of  claim 1 , wherein the second click coupling part comprises:
 a click coupling groove formed at at least one edge of the second block, the click coupling groove having smaller thickness than a body part at the side surface of the edge of the first block and being formed to be recessed, and   a pair of coupling blades positioned at both sides of the click coupling groove.   
     
     
         5 . The assembly blocks of  claim 4 , wherein the second block consists of at least two partial bodies which are divided about a lengthwise extension and comprises a rotation axis by which the partial bodies are pivotably coupled to each other, and the second click coupling part is formed at lengthwise outer edges of the respective partial bodies. 
     
     
         6 . The assembly blocks of  claim 4 , wherein click inserting projections are formed respectively to protrude on facing surfaces of the coupling blades. 
     
     
         7 . The assembly blocks of  claim 6 , wherein the click inserting projections are spaced apart from an inner end of the groove to be formed at outer ends of the groove so as to form a mounting part. 
     
     
         8 . The assembly blocks of  claim 4 , further comprising:
 a guide part formed at one of the edges of the second block on which the second click coupling part is formed, the guide part being recessed to divide the second click coupling part into at least two parts; and   a sub-click coupling part protruding on the guide part and configured to be inserted into a click coupling groove of the second click coupling part so as to be insert-coupled to the second click coupling part.   
     
     
         9 . The assembly blocks of  claim 8 , wherein the sub-click coupling part is formed on a line extended from the click coupling groove. 
     
     
         10 . The assembly blocks of  claim 8 , wherein a click inserting part is formed to protrude on both surfaces of the sub-click coupling part. 
     
     
         11 . The assembly blocks of  claim 10 , wherein the click inserting part is formed at an external end of the sub-click coupling part. 
     
     
         12 . The assembly blocks of  claim 6 , wherein a click inserting groove recessed to receive the click inserting projection and an inserting projection positioned away from the click inserting groove are formed on an outer surface of the coupling blades. 
     
     
         13 . The assembly blocks of  claim 8 , wherein the sub-click coupling part is formed at a central portion of the opposite edges of the body part. 
     
     
         14 . The assembly blocks of  claim 1 , wherein the second block is made from a bendable elastic material. 
     
     
         15 . The assembly blocks of  claim 8 , wherein an inner end of the guide part and an outer end of the second click coupling part insert-coupled to the sub-click coupling part through the guide part are formed to have curved surfaces which are engaged with each other. 
     
     
         16 . The assembly blocks of  claim 4 , wherein the second click coupling part positioned at lengthwise opposite ends of the second block is formed to have a width gradually decreasing toward an exterior side. 
     
     
         17 . The assembly blocks of  claim 5 , wherein click inserting projections are formed respectively to protrude on facing surfaces of the coupling blades. 
     
     
         18 . The assembly blocks of  claim 17 , wherein the click inserting projections are spaced apart from an inner end of the groove to be formed at outer ends of the groove so as to form a mounting part. 
     
     
         19 . The assembly blocks of  claim 5 , further comprising:
 a guide part formed at one of the edges of the second block on which the second click coupling part is formed, the guide part being recessed to divide the second click coupling part into at least two parts; and   a sub-click coupling part protruding on the guide part and configured to be inserted into a click coupling groove of the second click coupling part so as to be insert-coupled to the second click coupling part.   
     
     
         20 . The assembly blocks of  claim 19 , wherein the sub-click coupling part is formed on a line extended from the click coupling groove.
