Building block for construction set

Abstract

The invention relates to construction toys, is light-weight, low in material content, highly manufacturable, and requires less space for storage and transportation. The present building block for a construction set is made of molded paper pulp in tire form of a parallelepiped and consists of two separate hollow-bodied elements, the first of which comprises a face having at least four protuberances, and side walls, and the second of which has at least one protuberance; the two block elements are capable of being joined together by fitting the second element between the side walls of the first element, and one of said block elements comprises at least one limiting well.

1 . A Building block is made in the form of a parallelepiped and contains at least four protrusion located in two lines, on one of the faces, and at least one protrusion located on the opposite side, characterized in that the said block consists of two separate hollow elements, the first containing a face with at least four specified protrusions, as well as side walls, and the second element with at least one specified protrusion, both elements of the block are made with the possibility of their inter-connection by placing the second element between the side walls of the first element, and one of the specified elements of the block contains at least one limit well for bracing in the corresponding supporting platform of the other element, while both elements of the block are made of molded paper pulp. 
     
     
         2 . The Building block as per item  1 , characterized in that the side faces of the block are made flat. 
     
     
         3 . The Building block as per item  1 , characterized in that the dimensions of the protrusions on opposite sides of the block and their position relative to the side walls are made consistent, providing center-to-center connection of adjacent block, as well as connecting adjacent block with an offset relative to the center line of the block. 
     
     
         4 . The Building block as per item  1 , characterized in that the shape of the limit well for bracing in the corresponding supporting platform and the shape of the supporting platform of another element are made consistent in shape for inter-fixation of positions in the assembled block. 
     
     
         5 . The Building block as per item  1 , characterized in that the second element has an outward bend of the perimeter edge to abut against it the edges of the side walls of the first element in the assembled block. 
     
     
         6 . The Building block as per item  1 , characterized in that the planes of the side profiles of the elements are made with an inclination relative to the center line. 
     
     
         7 . The Building block as per item  1 , characterized in that every four protrusions on one of the faces form an imaginary square, and the protrusion on the opposite side of the block is located on the axis of the specified square.
