Toy construction system

Abstract

A toy construction system comprising a releasably connectable tendon or tether (“tendon”) to connect to at least two building blocks. The tendon being resiliently deformable and providing a range of motion for each of at least two blocks, relative to each other, in at least two Cartesian axes. The tendon having an engagement, and each block having a corresponding receiving element.

1 . A toy construction system comprising a releasably connectable tendon or tether (“tendon”) to connect to at least two building blocks, the tendon being resiliently deformable and providing a range of motion for each at least two blocks, relative to each other, in at least two Cartesian axes, the tendon having an engagement, and each block having a corresponding receiving element. 
     
     
         2 . A toy construction system of  claim 1 , wherein the tendon has a plurality of engagements. 
     
     
         3 . A toy construction system of  claim 2 , wherein the engagements are enlarged portions of the tendon. 
     
     
         4 . A toy construction system of  claim 1 , wherein the receiving element is a recess in a building block. 
     
     
         5 . A toy construction system of  claim 1 , wherein the toy construction system further comprises a building block having at least one elongate slotted aperture, another building block having at least one aperture, and a pin to engage through an aperture on at least two building blocks to thereby facilitate a connection that is hinged about the axis of the pin and slideable about the axis of slot elongation. 
     
     
         6 . A toy construction system of  claim 5 , wherein the pin has a head portion, and shaft portion extending downward from the head portion and a flared portion located at the base of the shaft portion. 
     
     
         7 . A toy construction system of  claim 6 , wherein the toy construction system further comprises a second building block having at least one aperture and a pin to engage through an aperture on each of the first and second building blocks to thereby facilitate a connection that is hinged about the axis of the pin. 
     
     
         8 . A toy construction system of  claim 6 , wherein the toy construction system further comprises a pin to engage through an aperture on each of the first and second building blocks to thereby facilitate a connection that is slideable about the axis of slot elongation. 
     
     
         9 . A toy construction system  claim 6 , wherein the pin has a head portion, and shaft portion extending downward from the head portion and a flared portion located at the base of the shaft portion. 
     
     
         10 . A toy construction system as claimed in  claim 8 , wherein the first or the second, or both building blocks has a plurality of projections extending upward from a top surface, and a plurality of recesses in a lower surface, the recesses shaped to frictionally engage the projections of another building block. 
     
     
         11 . A toy construction system of  claim 8 , wherein the first, or the second, or both building blocks has a plurality of receiving elements. 
     
     
         12 . A toy construction system of  claim 7 , wherein the toy construction system further comprises a releasably connectable tendon to connect to at least two building blocks, the tendon being resiliently deformable and providing a range of motion for each at least two blocks, relative to each other, in at least two Cartesian axis, the tendon having an engagement, and each block having a corresponding receiving element. 
     
     
         13 . A toy construction system of  claim 12 , wherein the tendon has a plurality of engagements. 
     
     
         14 . A toy construction system of  claim 13 , wherein the engagements are enlarged portions of the tendon. 
     
     
         15 . A toy construction system of  claim 12  wherein the engagements are held in the receiving elements by one or more lugs. 
     
     
         16 . A block having an outset profile and an inset profile whereby like blocks can be interconnected; wherein there is provided set down from the outset profile a recess to anchor a tendon or tether that is to project outwardly of the block. 
     
     
         17 . A block of  claim 16 , wherein the recess is defined to restrict rotation in the recess of a complementary tendon or tether. 
     
     
         18 . A toy construction system, in combination or assembly, comprising:
 a first block,   a second block, the first and second blocks optionally having features whereby they can, if desired, be interconnected onto the other, and   a flexible tether engageable to each block whereby, if desired, the blocks whether separate or mutually interconnected, can be linked by the tether.   
     
     
         19 . A toy construction system of  claim 18 , wherein the tether is resilient. 
     
     
         20 . A toy construction system of  claim 18 , wherein each of the blocks has an opening or other docking feature into which an anchorable end of the tether can be retained.
