         2 . The play structure according to  claim 1 , further comprising a system for assisting in the moving of the lower element in upright position. 
     
     
         3 . The play structure according to  claim 2 , the system for assisting including a linking arm that has a first end mounted in rotation on the lower element, as well as a second end mounted in translation on the base. 
     
     
         4 . The play structure according to  claim 3 , the system for assisting including spring means mounted on the base on either side of the second end of the linking arm. 
     
     
         5 . The play structure according to  claim 4 , the spring means being in constrained position when the lower element is in folded down position. 
     
     
         6 . The play structure according to  claim 3 , further comprising a system for blocking the lower element in upright position. 
     
     
         7 . The play structure according to  claim 6 , the system for blocking comprising means for blocking the linking arm in translation and/or in rotation. 
     
     
         8 . The play structure according to  claim 7 , the system for blocking including studs carried by one among the linking arm and the lower element, said studs being intended to be blocked in a device for receiving carried by the other among the lower element and the linking arm when said lower element is in upright position. 
     
     
         9 . The play structure according to  claim 1 , the lower element including two legs mounted on either side of its lower end and intended to rest on the ground when said lower element is in upright position. 
     
     
         10 . The play structure according to  claim 1 , further comprising a device for locking the upper element in deployed position. 
     
     
         11 . The play structure according to  claim 10 , the device for locking comprises a hook mounted on one among the upper and lower elements, said hook being hooked manually on the other among said lower and upper elements when said upper element is in deployed position. 
     
     
         12 . The play structure according to  claim 1 , the upper element including two pairs of upper and lower parallel bars that each have a rear end mounted in rotation on a free end of the lower element and a front end on which the basketball backboard is mounted in rotation. 
     
     
         13 . The play structure according to  claim 1 , the lower element including a first portion mounted slidingly in a second portion between a retracted position in said second portion and a raised position outside of said second portion, said lower element being provided with a system for actuating the movement of said first portion in raised position. 
     
     
         14 . The play structure according to  claim 13 , the system for actuating including a strap of which a first end is fastened to the second portion, with said strap being mounted on a means for winding around its second end, with the first portion bearing on said strap between its first and second ends in order to be able to be moved in raised—respectively retracted—position by winding—respectively unwinding—of said strap. 
     
     
         15 . The play structure according to  claim 1 , the base including:
 a central frame on which the lower element is mounted in rotation;   wheels mounted on said frame in order to allow said structure to be moved.   
     
     
         16 . The play structure according to  claim 15 , at least some of the wheels being arranged in order to be able to be filled with a ballast material in order to form a counterweight to the element in upright position in order for said structure to be used.
