Component Kit for Assembling Toy Buildings

Abstract

Component kit for assembling toy buildings, com prising components, preferably made of wood and having various shapes, provided with properly located bores and connecting elements for said components, preferably made of plastic, wherein, according to the invention, a splined rod ( 10 ) is provided, which has, on almost all its external surface, a plurality of longitudinal lands ( 11 ), which alternate with the same number of grooves ( 12 ), said lands ( 11 ), at a short distance from both the ends of the splined rod, ending with arched chamfers ( 13 ), said splined rod being apt to support other toy building components, such as sleeves ( 20 ), right-angled connecting ele ments ( 30 ), inserts ( 40 ), end elements ( 50 ), all of which being provided with coherent bores, i.e. with coherent shape and dimensions relative to the charac teristics of said splined rod ( 10 ).

1 . Component kit for assembling toy buildings, comprising components having various shapes, having properly located bores and connecting elements for said components, wherein it includes a splined rod which has, on almost its whole surface, a plurality of longitudinal lands alternated with the same number of grooves, the lands, at a short distance from both the ends of the splined rod, ending with arched chamfers, said splined rod being apt to support other toy building components provided with coherent bores, i.e. coherently shaped and sized relative to the characteristics of said splined rod, or cylindrical bores, wherein the component kit comprises an insert in which a bore is made, coherently shaped in accordance with the shape and dimensions of the splined rod which can be received therein in perfect coupling relationship, wherein said insert is intended to be inserted within a bore made in a building block of the toy building. 
     
     
         2 . Component kit for assembling toy buildings according to  claim 1 , comprising a connecting sleeve having a central through-hole provided with annularly adjacent axial grooves capable of accommodating said splined rod and exactly coupling with said splined rod. 
     
     
         3 . Component kit for assembling toy buildings according to  claim 2 , wherein said grooves of the connecting sleeve are interrupted in the middle by inwardly directed restricting protrusions, which act as stops for splined rods inserted at the two ends of the sleeve in order to limit the grade of insertion thereof. 
     
     
         4 . Component kit for assembling toy buildings according to  claim 1 , comprising a connecting element formed by a stem and a head, said stem having a blind hole which is properly splined in order to receive and couple with a splined rod or with a part thereof, the head having a coherently splined bore to receive and couple itself with an end of the splined rod, the axes of the splined bores being arranged at 90° to each other. 
     
     
         5 . Component kit for assembling toy buildings according to  claim 1 , wherein said insert consists in an essentially cylindrical body wherein a bore is made, coherently shaped in accordance with the shape and dimensions of the rod which can be received therein in perfect coupling relationship, the insert ending, at the front side, with a bearing flange collar and, at the rear side, with an invitation chamfer whereas the substantially cylindrical body has orientating conic protrusions and restraint axial ribs. 
     
     
         6 . Component kit for assembling toy buildings according to  claim 1 , comprising an end element made of a peripherally chamfered disc, where a bore is made, coherently shaped in respect to shape and dimensions of rod which can be received therein, the end element having also orienting rear conic protrusions and arched restraining ribs. 
     
     
         7 . Component kit for assembling toy buildings according to one or more of the preceding claims, wherein said bored components are made of wood, whereas said connecting element of said bored components are made of plastic.
