Block Toy

Abstract

By a combination of a plurality of blocks 11 in which a plurality of projecting portions 37 which are formed into the same cylindrical shape are provided on an upper surface of a rectangular parallelepiped base portion 31 at intervals of several millimeters, the base portion 31 has a rectangular parallelepiped interior space which is made to open downwards so as to enable the accommodation of projecting portions 37 of other blocks, and the cylindrical projecting portions 37 of the other blocks are made to be held by side wall panels 33 of the base portion 31 , a drawback that the change in shape of a shaped structure becomes less conspicuous is eliminated irrespective of a reduction in the number of types of blocks with respect to their shapes.

1 . A block toy characterized by a combination of a plurality of blocks in which a plurality of projecting portions which are formed into the same cylindrical shape are provided on an upper surface of a rectangular parallelepiped base portion at intervals of several millimeters, the base portion has a rectangular parallelepiped interior space which is made to open downwards so as to enable the accommodation of projecting portions of other blocks, and the cylindrical projecting portions of the other blocks are made to be held by side wall panels of the base portion. 
     
     
         2 . The block toy according to  claim 1 , characterized in that values of height and diameter of each projecting portion are made to be values which are smaller than a value of an interspace between centers of the projecting portions. 
     
     
         3 . The block toy according to  claim 1 , characterized in that the base portion is made into a rectangular parallelepiped shape in which its height is several millimeters which is equal to or slightly smaller than several millimeters which is referred to as the interspace between the centers of the cylindrical projecting portions and length and width of the base portion are substantially equal to the multiplication of several millimeters which is referred to as the interspace between the centers of the projecting portions by an integer. 
     
     
         4 . The block toy according to  claim 1 , characterized in that blocks are combined which are different in number of projecting portions which are provided on the upper surface of the base portion. 
     
     
         5 . The block toy according to  claim 3 , characterized in that blocks are combined which are different in number of projecting portions which are provided on the upper surface of the base portion. 
     
     
         6 . The block toy according to  claim 1 , characterized in that blocks are included which have two auxiliary walls which are formed into a thin plate-like shape and are provided in parallel in the interior space of the base portion, so that cylindrical projecting portions of other blocks are held by the side wall panels of the base portion and the auxiliary walls. 
     
     
         7 . The block toy according to  claim 3 , characterized in that blocks are included which have two auxiliary walls which are formed into a thin plate-like shape and are provided in parallel in the interior space of the base portion, so that cylindrical projecting portions of other blocks are held by the side wall panels of the base portion and the auxiliary walls. 
     
     
         8 . The block toy according to  claim 4 , characterized in that blocks are included which have two auxiliary walls which are formed into a thin plate-like shape and are provided in parallel in the interior space of the base portion, so that cylindrical projecting portions of other blocks are held by the side wall panels of the base portion and the auxiliary walls. 
     
     
         9 . The block toy according to  claim 5 , characterized in that blocks are included which have two auxiliary walls which are formed into a thin plate-like shape and are provided in parallel in the interior space of the base portion, so that cylindrical projecting portions of other blocks are held by the side wall panels of the base portion and the auxiliary walls. 
     
     
         10 . The block toy according to  claim 1 , characterized by a combination of auxiliary blocks in which a single cylindrical projection is provided on a base portion which is slightly larger than the cylindrical projection and which has an interior space which is made to open downwards so as to enable the accommodation of one of cylindrical projections of other blocks and the blocks which have the plurality of cylindrical projections.
