Puzzle

Abstract

The present invention is added to a puzzle corresponding to No. 2001-0007848 of the Korea Utility Model Application, making the user fit desired pieces of the puzzle by putting fixing projections on inner sides of the pieces and putting fixing flat boards having rubber property between upper and lower chains, in addition to the existing method of combining chains to rotational shafts on the center of the pieces. Thus, the gatherings of each piece can be stably fixed through internal pressure actions. According to the present invention, triangular, rectangular, and hexagonal upper and lower pieces are solved by using pressure of the fixing flat boards in order to prevent thin upper and lower chains from shaking, while the respective fixing projections fix the chains by surrounding empty spaces or the exterior of the chains.

1 . A puzzle, comprising:
 fixing projections( 500 ) located on inner sides of upper/lower pieces( 100 ).   
   
   
       2 . The puzzle of  claim 1 , wherein fixing flat boards( 400 ) are located between upper/lower chains( 300 ), and prevent the upper/lower chains( 300 ) fixed to the fixing projections( 500 ) from minutely shaking. 
   
   
       3 . The puzzle of  claim 1 , wherein in case of triangular pieces( 100 ), 3 fixing projections( 500 ) are located on each edge of parts on inner sides of the upper/ lower pieces( 100 ). 
   
   
       4 . The puzzle of  claim 1 , wherein rectangular pieces( 100 ) have 8 fixing projections( 500 ) on each edge of the parts on the inner sides of the upper/lower pieces( 100 ), thus the fixing projections( 500 ) are located on each edge and in every middle part of the edges, and fixing projections( 500 ) located in the middle part have grooves that do not interfere with centers of the chains( 300 ). 
   
   
       5 . The puzzle of  claim 1 , wherein hexagonal pieces( 100 ) have 6 fixing projections( 500 ) on each edge, on the inner sides of the upper/lower pieces( 100 ), thus the fixing projections( 500 ) are located in every middle part of the edges, and fixing projections( 500 ) located in the middle part have grooves that do not interfere with the centers of the chains( 300 ).
