Abstract: A binding assembly comprising a binding which comprises a boot platform and a positioning unit, wherein the positioning unit secures the binding assembly to a sports board. The positioning unit comprises an anchoring subunit comprising a central member; and a locking subunit comprising a handle in communication with an engaging member. At one moment the handle exerts a first force on the engaging member thereby causing the engaging member to move towards the central member until the engaging member is in contact with the central member, at which point the handle is maneuvered to lock the binding assembly into position. At another moment, the handle exerts a second force on the engaging member thereby causing the engaging member to move away from the central member, thereby unlocking the binding assembly. When unlocked, the binding is rotatable about a central longitudinal axis, and when unlocked, the binding is fixed in position.
