3d maze

Abstract

The present invention provides a 3D maze made of corrugated paper that can be assembled by users. The 3D maze includes an external housing body and a layered inner body. The layered inner body is located inside the external housing body. The external housing body has a first entrance/exit for entering the 3D maze. The layered inner body is also disposed with a second entrance/exit, a third entrance/exit, or a fourth entrance/exit for entrance and exit of the 3D maze.

What is claimed is: 
     
         1 . A 3D maze, comprising:
 an external housing body, comprising a plurality of joint portions adjacent to each other, each joint portion comprising a folding portion and a connection portion, the folding portion and the connection portion being connected to each other, each folding portion comprising an extending buckle, each connection portion comprising a buckle hole, the extending buckle being buckled in the buckle hole of the connection portion of one adjacent joint portion; and   a layered inner body, comprising a plane body and a plurality of standing joint bodies, the plurality of standing joint bodies joggled to the plane body;   wherein the layered inner body is located inside the external housing body, at least one of the joint portions has a first entrance/exit, and at least of the standing joint bodies has a second entrance/exit.   
     
     
         2 . The 3D maze of  claim 1 , wherein the 3D maze is made of corrugated paper and each joint portion is a polygonal plane. 
     
     
         3 . The 3D maze of  claim 1 , wherein the layered body further comprises a second plane body and a plurality of second standing joint bodies, the plurality of second standing joint bodies respectively are joggled to the second plane body, and the plurality of second standing joint bodies are located above the plane body. 
     
     
         4 . The 3D maze of  claim 3 , wherein the second plane body is smaller than the plane body, and the plane body comprises a third entrance/exit. 
     
     
         5 . The 3D maze of  claim 1 , wherein the joint portion comprises a second extending buckle and a second buckle hole, and the second extending buckle is buckled in the second buckle hole of the connection portion of one adjacent joint portion. 
     
     
         6 . The 3D maze of  claim 1 , further comprising a ball located inside the external housing body, and the ball further comprises an inside space for placing an attractive object. 
     
     
         7 . The 3D maze of  claim 1 , further comprising a folding hook body, and the folding hook body is hooked at any of the plurality of joint portions. 
     
     
         8 . The 3D maze of  claim 1 , wherein the external housing body or the layered inner body is made of corrugated paper. 
     
     
         9 . A 3D maze, comprising:
 an external housing body, comprising a plurality of joint portions and a plurality of buckle units, each of the joint portions having a plurality of connection portions adjacent to each and each of the connection portions having a buckle hole, each buckle hole corresponding to each buckle unit such that the plurality of joint portions can be connected to each other;   a layered inner body comprising a plane body and a standing joint body, the standing joint body being joggled to the plane body, and the standing joint body comprising a plurality of standing plate;   wherein the layered inner body is located inside the external housing body, at least one of the joint portions has a first entrance/exit, and the standing joint portion has a second entrance/exit.   
     
     
         10 . The 3D maze of  claim 9 , wherein the 3D maze is made of corrugated paper and each connection portion is a polygonal plane. 
     
     
         11 . The 3D maze of  claim 9 , further comprising a ball located inside the external housing body, and the ball further comprises an inside space for placing an attractive object. 
     
     
         12 . The 3D maze of  claim 9 , further comprising a folding hook body, the folding hook body being hooked at any of the plurality of joint portions. 
     
     
         13 . The 3D maze of  claim 9 , wherein the external housing body or the layered inner body is made of corrugated paper. 
     
     
         14 . A folding hook body capable of being hooked at an external housing body of a 3D maze, the folding hook body comprising:
 a corrugated paper main body having a substantial rectangular shape;   a plurality of knife sutures separately located on one side of the corrugated paper main body;   a plurality of pressure lines separately located on another side of the corrugated paper main body;   a hook ear portion located at any of short sides of the corrugated paper main body;   whereby the corrugated paper main body is folded along the plurality of pressure lines and the plurality of knife sutures such that the hook ear portion is located at the most exterior side, and the hook ear portion is capable of being hooked at the external housing body of the 3D maze and the surface having the plurality of knife sutures faces outwardly.   
     
     
         15 . The folding hook body of  claim 14 , further comprising a second hook ear portion located at another short side of the corrugated paper main body
