Solid puzzle

Abstract

A solid puzzle including a solid polyhedral main body having multiple faces, multiple unit pieces and engaging structures for fixing the unit pieces on the faces of the main body. The main body has a certain volume and several faces. By means of the engaging structures, the unit pieces are assembled and attached to the faces of the main body. Each unit piece has at least one recessed section and at least one projecting section. The shape of the projecting section is complementary to the shape of the recessed section. One of the recessed section and projecting section of at least one unit piece attaching to each face of the main body covers an adjacent face. The recessed section or projecting section covering the adjacent face is inserted with the corresponding projecting section or recessed section of another unit piece attaching to the adjacent face.

1 . A solid puzzle comprising a solid polyhedral main body having multiple faces, multiple unit pieces which can be assembled and attached to the faces of the main body by way of insertion and engaging structures for fixing the unit pieces on the faces of the main body, wherein the main body has a certain volume and several faces and each unit piece has a form of a polygon, by means of the engaging structures, the unit pieces being assembled and attached to the faces of the main body, each unit piece having at least one recessed section and at least one projecting section, the shape of the projecting section being complementary to the shape of the recessed section, one of the recessed section and projecting section of at least one unit piece attaching to at least one face of the main body covering an adjacent face, the recessed section or projecting section covering the adjacent face being inserted with the corresponding projecting section or recessed section of another unit piece attaching to the adjacent face.  
     
     
         2 . The solid puzzle as claimed in  claim 1 , wherein the main body is a cubic body with six faces adjacent to each other.  
     
     
         3 . The solid puzzle as claimed in  claim 1 , wherein the main body is a close polyhedral body having multiple polygonal faces, the main body substantially having a form of a spherical body.  
     
     
         4 . The solid puzzle as claimed in  claim 1 , wherein the main body is composed of a first hollow half body and a second hollow half body which are associated by way of insertion, whereby an internal receiving space is defined in the main body.  
     
     
         5 . The solid puzzle as claimed in  claim 1 , wherein the first and second half bodies are respectively formed with engaging sections for engaging the first and second half bodies with each other to form a complete solid polyhedral main body.  
     
     
         6 . The solid puzzle as claimed in  claim 1 , wherein at least two unit pieces are attached to each face of the main body, whereby one of the recessed section and projecting section of each unit piece attaching to each face of the main body will cover an adjacent face, the recessed section or projecting section covering the adjacent face being inserted with the corresponding projecting section or recessed section of another unit piece attaching to the adjacent face.  
     
     
         7 . The solid puzzle as claimed in  claim 1 , wherein several unit pieces are attached to each face of the main body, whereby the recessed section and projecting section of the unit piece positioned in the middle of the face of the main body will not cover the adjacent face, while one of the recessed section and projecting section of the unit piece positioned on the periphery of the face will still cover the adjacent face of the main body, the recessed section or projecting section covering the adjacent face being inserted with the corresponding projecting section or recessed section of the unit piece in the middle of the adjacent face.  
     
     
         8 . The solid puzzle as claimed in  claim 1 , wherein the engaging structures include multiple engaging holes formed on the faces of the main body and multiple engaging bosses formed on the faces of the unit pieces, which faces are attached to the main body, the engaging bosses corresponding to the engaging holes, whereby the engaging bosses can be engaged in the engaging holes to fix the unit pieces on the faces of the main body.
