Magnet And Pin for Block Toy

Abstract

A rotary magnet and a fastening pin for block toys are disclosed. The object of the present invention is to provide a structure such that the production cost can be reduced, the magnet and the pin can be easily installed in a block, and appropriate attractive force can be easily generated between blocks. The fastening pin ( 11 ) include a fastening plate part ( 12 ), which has a diameter suitable for fitting the fastening plate part into a seating depression ( 2 ) of the block ( 1 ), and a pin part ( 13 ), which has a height greater than that of the rotary magnet ( 14 ). The rotary magnet ( 14 ) has an N pole and an S pole on the left and right parts thereof. A through hole ( 15 ) is formed through the center of the rotary magnet ( 14 ), so that the pin part ( 13 ) can be inserted into the through hole ( 15 ).

1 . A rotary magnet and a fastening pin for block toys, in which blocks are connected to each other using permanent magnets, wherein
 the fastening pin ( 11 ) comprises: a fastening plate part ( 12 ) having a diameter suitable to fit the fastening plate part into a seating depression ( 2 ) of a block ( 1 ); and a pin part ( 13 ), having a height greater than a height of the rotary magnet ( 14 ), and   the rotary magnet ( 14 ) has an N pole and an S pole on left and right parts thereof, with a through hole ( 15 ) formed through a central portion of the rotary magnet ( 14 ), so that the pin part ( 13 ) is inserted into the through hole ( 15 ).   
     
     
         2 . The rotary magnet and the fastening pin for block toys according to  claim 1 , wherein a tool insert groove ( 18 ) for insertion of a tool is formed in the fastening plate part ( 12 ) of the fastening pin ( 11 ), and an external thread ( 16 ) is formed on the pin part ( 13 ). 
     
     
         3 . The rotary magnet and the fastening pin for block toys according to  claim 1 , wherein a hook ( 17 ) is provided on an end of the pin part ( 13 ).
