Toys configured for use with other toy systems

Abstract

Disclosed herein are toy building units of a toy building set. The building units comprise a sheet of a material that defines a net of a polyhedron, the sheet having a plurality of sections, each section being connected to another section with a hinge.

What is claimed is: 
     
         1 . A building unit of a toy building set, the building unit comprising:
 a first material forming at least four sections, each comprising a plurality of edges;   a second material laminating the first material over a first surface;   a first portion of the plurality of edges comprising a plurality of integral hinges connecting the at least four sections, the building unit configured to fold and unfold over multiple cycles at the plurality of integral hinges from a flat position into a closed position which is a polyhedron with a hollow interior, wherein the integral hinges comprise a cut at least partially through the first material on a second surface opposite the first surface; and   a second portion of the plurality of edges comprising integral teeth and recesses, the integral teeth comprising a tip and at least one recess-adjacent surface, the integral teeth of a first of the plurality of edges configured to fit with the recesses of a second of the plurality of edges in a closed position.   
     
     
         2 . The building unit of  claim 1 , further comprising a plurality of holes through the first material and the second material configured to receive an array of protrusions from a secondary toy component. 
     
     
         3 . The building unit of  claim 2 , wherein the secondary toy component comprises one or more wheel configured to support the building unit. 
     
     
         4 . The building unit of  claim 3 , further comprising a secondary cut through the first material and the second material configured to receive the one or more wheels in a closed position. 
     
     
         5 . The building unit of  claim 1 , wherein the polyhedron is a cube, and wherein the cut maintains a substantially right angle of the integral hinges in a closed position. 
     
     
         6 . The building unit of  claim 1 , wherein the second material is configured to maintain a structural integrity of the integral hinges without the first material. 
     
     
         7 . The building unit of  claim 1 , wherein the cut is configured to limit crimping of the first material in the closed position. 
     
     
         8 . The building unit of  claim 1 , wherein the second material is between 0.5 mm and 5 mm thick. 
     
     
         9 . The building unit of  claim 1 , wherein the second material is between ⅕ th  and 1/20 th  of a total thickness of the building unit in a flat position. 
     
     
         10 . The building unit of  claim 1 , wherein the second material is adhered to the first material. 
     
     
         11 . The building unit of  claim 1 , wherein the integral teeth and at least one recess-adjacent surface are configured to interleave to form a closed edge of the building unit wherein friction between surfaces of one or more interleaved teeth holds the building unit together in the closed position. 
     
     
         12 . The building unit of  claim 11 , wherein the integral teeth are configured to deform in the closed position, wherein the deformation increases the friction holding an edge of the building unit together. 
     
     
         13 . The building unit of  claim 1 , wherein the second material is configured to line the hollow interior in the closed position. 
     
     
         14 . The building unit of  claim 1 , wherein the first material comprises an image receptive material. 
     
     
         15 . The building unit of  claim 14 , wherein the image receptive material is configured to receive at least one of drawing, painting, or coloring. 
     
     
         16 . The building unit of  claim 14 , wherein the image receptive material comprises a printed digital image. 
     
     
         17 . A method of manufacturing a toy building unit, the method comprising:
 adhering a second material to a first surface of a first material;   cutting through the first material and second material to form a second portion of a plurality of edges comprising integral teeth and recesses, the integral teeth comprising a tip and at least one recess-adjacent surface, the integral teeth of a first of the plurality of edges configured to fit with the recesses of a second of the plurality of edges in a closed position; and   cutting at least partially through the first material on a second surface to form a first portion of the plurality of edges comprising a plurality of integral hinges connecting at least four sections, the building unit configured to fold and unfold over multiple cycles at the plurality of integral hinges from a flat position into a closed position which is a polyhedron with a hollow interior, wherein the second surface is opposite the first surface.   
     
     
         18 . The method of  claim 17 , further comprising applying a digital image to the second surface. 
     
     
         19 . The method of  claim 18 , further comprising:
 receiving an input digital image;   identifying a human face in the input digital image using a machine learning algorithm;   extracting the human face from the input digital image; and   storing the extracted human face as the digital image.   
     
     
         20 . The method of  claim 17 , further comprising cutting a plurality of holes through the first material and the second material configured to receive an array of protrusions from a secondary toy component.
