1. A folding wheel chock comprising:
a stop ramp having a front face shaped to be interfaced with a vehicle wheel, extending from a first support base to a first vertex, and
a support wall, extending from a second support base to a second vertex,
wherein the stop ramp and the support wall are hinged by at least one pivot pin at the respective first and second vertexes to rotate between an in-use or working configuration, in which the stop ramp and the support wall form a wedge or bridge-shaped structure tapering towards the at least one pivot pin, and a non-use or resting configuration in which the stop ramp and the support wall are arranged mutually parallel,
wherein at the second vertex, the support wall has at least one abutment shaped to create a limit stop and a support against a corresponding stop of the stop ramp, opposite to said front face, the second support base comprises a fastening element to the ground, the fastening element at least partially protruding from the second support base to promote blocking of the support wall to the ground, and the folding wheel chock comprises a tip acting as a portion of a first interface with the vehicle wheel, said tip being moveable relative to the stop ramp at the first support base and being movable from an extracted or working configuration, in which it protrudes towards an associable wheel as an extension of the stop ramp, on a side opposite to the support wall, to a retracted or resting configuration in which it is arranged at least partially folded or aligned on the stop ramp and/or the support wall.
