Constructional building set comprising building elements with object container, and such building elements

Abstract

A constructional building element comprising a top face, a plurality of side walls extending downwardly from the top face, a plurality of coupling studs which are arranged on the top face, a plurality of cavities arranged in a two-dimensional periodical pattern at the bottom of the building element to receive coupling studs in frictional engagement and at least one container with opaque external surface and opening to accomadate favorite objects which cannot be easily joined. The object container with opaque external surface can be frictionally releasable from the building element. The object container with opaque external surface accomodates a surface area with coupling studs/cavities to frictionally engage with favorite objects. The building element may accommodate multiple containers with opaque external surfaces. The object container with opaque external surface may have tray to accommodate favorite objects.

 a. a top face.   b. a plurality of side walls extending downwardly from the top face.   c. a plurality of coupling studs which are arranged in a two-dimensional periodical pattern on the top face   d. a plurality of cavities arranged in a two-dimensional periodical pattern between the side walls to receive the coupling studs in frictional engagement   e. at least one object container.   
   
   
       2 . A building element according to  claim 1 , wherein said object container can frictionally engage with the said building element. 
   
   
       3 . A building element according to  claim 1 , wherein said object container has a plurality of three dimensional spaces for objects. 
   
   
       4 . A building element according to  claim 1 , wherein said object container has a cover. 
   
   
       5 . A building element according to  claim 1 , wherein said object container has inlet/outlet for fluids. 
   
   
       6 . A building element according to  claim 1 , wherein said object container can sustain freezing temperature. 
   
   
       7 . A building element according to  claim 1 , wherein said object container has at least one surface with cavities to engage objects. 
   
   
       8 . A building element according to  claim 1 , wherein said object container has at least one surface with holes to engage objects. 
   
   
       9 . A building element according to  claim 1 , wherein said object container has at least one surface with coupling studs to engage objects. 
   
   
       10 . A building element according to  claim 1 , wherein top face area of the said building element is comprised of multiple subareas. 
   
   
       11 . A building element according to  claim 1 , wherein the said cavities to accommodate said coupling studs are positioned in different subareas. 
   
   
       12 . A construction building set containing at least one building element according to  claim 1 . 
   
   
       13 . A construction building set according to  claim 12  which contains a literature with information about different arrangements of the building elements.
