Toy block structure

Abstract

Toy blocks can be easily separated. A toy block structure is formed by fitting toy blocks including concave and convex portions, and a gap wherein a nail of a hand can enter is formed at a border portion between one adjacent toy block and another adjacent toy block of the toy block structure.

What is claimed is: 
     
         1 . A toy block structure, comprising:
 one and another toy blocks fitted each other and including concave and convex portions,   wherein the convex portion is provided on a side of a top face of the another toy block and fits in the concave portion provided on a side of a bottom face of the one toy block so as to form the toy block structure, and   a gap wherein a nail of a hand is adapted to enter is formed at a border portion between the one toy block and the another toy block.   
     
     
         2 . A toy block structure according to  claim 1 , wherein the another toy block includes a corner portion at a top face thereof formed in a taper face or a round face, or at a face which is lower than the top face so that a gap, wherein a nail of a hand is adapted to enter, is formed at a border portion between the one toy block and the another toy block adjacent to each other. 
     
     
         3 . A toy block structure according to  claim 1 , wherein the one toy block includes a corner portion at a bottom face thereof formed in a taper face or a round face, or at a face which is higher than the bottom face so that a gap, wherein a nail of a hand is adapted to enter, is formed at a border portion between the one toy block and the another toy block adjacent to each other. 
     
     
         4 . A toy block structure according to  claim 1 , wherein the another toy block includes an outer periphery at a top face thereof formed in a taper face or a round face, or at a face which is lower than the top face so that a gap, wherein a nail of a hand is adapted to enter, is formed between an outer periphery of a bottom face of the one toy block, and the taper face or the round face, or the face which is lower than the top face of the outer periphery at the top face of the another toy block. 
     
     
         5 . A toy block structure according to  claim 1 , wherein the one toy block includes an outer periphery at a bottom face thereof formed in a taper face or a round face, or a face which is higher than the bottom face so that a gap, wherein a nail of a hand is adapted to enter, is formed between the taper face or the round face, or the face which is higher than the bottom face, and an outer periphery of a top face of the another toy block adjacent to each other. 
     
     
         6 . A toy block structure, comprising toy blocks fitted each other, each toy block comprising:
 a base having a top face, and a bottom face on a side opposite to the top face,   a convex portion formed on the top face,   a concave portion formed on the bottom face to be able to fit in the convex portion, and   a top-face projecting portion projecting to a side of the toy block from the top face, or an outward projecting portion projecting outwardly from the side of the toy block, or a bottom-face projecting portion projecting to the side of the toy block from the bottom face, or a side-face concave portion provided on the side of the toy block,   wherein the top-face projecting portion, or the outward projecting portion, or the bottom-face projecting portion, or the side-face concave portion is formed in a locking portion wherein a nail of a hand is adapted to engage.   
     
     
         7 . A toy block structure, comprising:
 one toy block having a concave portion provided on a side of a bottom thereof,   another toy block having a convex portion provided on a side of a top thereof fitting in the concave portion to form the toy block structure, and   a face locked portion provided on the top of the another toy block, or a side of the another toy block, or   a concave-portion locked portion provided on the convex portion or the side face thereof, a locking member engaging the face locked portion or the concave-portion locked portion.
