Elastic toy building bricks

Abstract

The invention provides a toy building brick made of a soft material and joinable to at least one other building brick. Additionally, disclosed is a solid building brick system of a soft elastic material, which enables the detachably joining of said bricks with each other, allowing the assembly of structures whose dimensions exceed the state of the art and, maintaining the firmness in said structures.

1 . A building brick, wherein the brick includes a rectangular parallelepiped shape having a length, a width and a height, and wherein the brick is capable of being detachably joined to at least one other brick from a male-female joining relationship, the brick comprises:
 at least one male joining element whose location at one face of the brick varies according to the magnitude of the length of the brick; and   at least one female joining element whose location at one opposite face of the brick depends on the location of the male joining element,   wherein the brick is made of a soft elastic material, wherein the male-female relationship is not perfect.   
     
     
         2 . The building brick according to  claim 1 , wherein the widths of the at least one female joining element are smaller than the widths of the at least one male joining element. 
     
     
         3 . The building brick according to  claim 2 , wherein the widths of the at least one female joining element are at least one (1) mm smaller than the widths of the at least one male joining element. 
     
     
         4 . The building brick according to  claim 1 , wherein the building brick further includes at least one relief bore around at least one of the at least one female joining element. 
     
     
         5 . The building brick according to  claim 1 , wherein the length of the building brick is greater than 20 cm. 
     
     
         6 . The building brick according to  claim 1 , wherein the material is selected from the list of: ethylene-vinyl acetate, polyurethane foam, polyethylene foam and polystyrene foam. 
     
     
         7 . The building brick according to  claim 1 , wherein at least one male joining element includes a chamfer around its base. 
     
     
         8 . The building brick according to  claim 7 , wherein the chamfer has a curved shape. 
     
     
         9 . The building brick according to  claim 7 , wherein the chamfer is angled at 45 degrees with respect to the one face of the building brick. 
     
     
         10 . A set of building bricks, comprising a plurality of building bricks made of a first material, wherein each brick is detachably joined to at least one other brick by a non-perfect male-female element relationship, wherein the force of said joining and detachment depends on the elastic deformation of the first material. 
     
     
         11 . The set of building bricks according to  claim 10 , wherein the non-perfect male-female relationship is defined due to the female element being smaller than the male element. 
     
     
         12 . The set of building bricks according to  claim 11 , wherein the female element is at least one (1) mm smaller than the male element. 
     
     
         13 . The set of building bricks according to  claim 10 , wherein each brick of the set of bricks further includes at least one relief bore around the female element. 
     
     
         14 . The set of building bricks according to  claim 10 , wherein the first material is selected from the list of: ethylene-vinyl acetate, polyurethane foam, polyethylene foam and polystyrene foam. 
     
     
         15 . A building brick configured to be detachably joined to at least one other building brick by a male-female joining relationship, wherein the building brick comprises:
 at least one male joining element located on one face of the building brick, wherein each of the at least one male joining elements have a first diameter; and   at least one female joining element that is located on a face opposite of the one face of the building brick, wherein each of the at least one female joining elements have a second diameter,   wherein the location of each of the at least one female joining element depends on the location of a corresponding one of the at least one male joining element,   wherein the male-female joining relationship between building bricks comprises male joining elements having the first diameter being inserted into female joining elements having the second diameter,   wherein the second diameter is smaller than the first diameter, and   wherein the brick is made of an elastic material.   
     
     
         16 . The building brick according to  claim 15 , wherein the building brick further includes at least one relief bore around at least one female joining element. 
     
     
         17 . The building brick according to  claim 16 , wherein the at least one relief bore comprises a non-circular relief bore. 
     
     
         18 . The building brick according to  claim 15 , wherein at least one male joining element includes a chamfer around its base. 
     
     
         19 . The building brick according to  claim 15 , wherein the first diameter is a multiple of a length of the building brick. 
     
     
         20 . The building brick according to  claim 15 , wherein the second diameter is a multiple of a length of the building brick.
