Assembled block

Abstract

A block which can be easily assembled into a large variety of shapes and sizes using a smaller number of kinds of joints at a low cost. The assembled block includes equilateral triangular block plates, square block plates, and joints through which the block plates are coupled together. Each of the joints is formed of a single, flexible and bendable plate having wing portions on both sides thereof. The block plates are made of a flexible material and have edges and receptacles each provided along one of the edges for accepting one of the wing portions of the joints. The receptacles are each formed with a guide pocket. Any two the block plates can be coupled together through any of the joints by inserting the respective wing portions of the joint into one of the receptacles of one of the two block plates through the corresponding guide pocket and into one of the receptacles of the other of the two block plates through the corresponding guide pocket.

1 . An assembled block comprising equilateral triangular block plates, square block plates, and joints through which said block plates are coupled together, each of said joints being formed of a single, flexible and bendable plate having wing portions on both sides thereof, said block plates being made of a flexible material and having edges and receptacles each provided along one of said edges for accepting one of said wing portions of said joints, said receptacles being each formed with a guide pocket, whereby any two of said block plates can be coupled together through any of said joints by inserting the respective wing portions of said joint into one of said receptacles of one of said two block plates through the corresponding guide pocket and into one of said receptacles of the other of said two block plates through the corresponding guide pocket.  
   
   
       2 . The assembled block of  claim 1  wherein a plurality of said joints can be inserted simultaneously into any of said receptacles of any of said block plates with each joint superposed on the others.  
   
   
       3 . The assembled block of  claim 1  further comprising an arrangement for preventing any of said wing portions from slipping out of any of said receptacles once the former is inserted in the latter.  
   
   
       4 . The assembled block of  claim 1  wherein each of said block plates comprises two base plates superposed one on the other, said receptacles being defined between said two base plates.  
   
   
       5 . The assembled block of  claim 1  wherein each of said block plate comprises a base plate and extensions each extending from and folded along one of said edges so as to be superposed on one side of said base plate, said receptacles being defined by cuts each formed along one of said edges.
