Abstract

Roulette of adjustable length, comprising two telescopic tubes, a handle fixed on one of the tubes and a locking mechanism designed to block the two tubes relative to each other, characterized in that it also comprises a unit with piston and with cylinder containing a fluid under pressure and comprising a piston rod fixed on one of said tubes, a cylinder fixed on the other tube, and a piston coupled to the piston rod and that can slide on the cylinder establishing a tight contact with the wall of the piston. Cylinder, the piston dividing the inside of the cylinder containing the fluid under pressure in two chambers communicating by means of a normally closed communication conduit, the piston rod being locked relative to the cylinder while the communication conduit is closed, while that fluid under pressure has a tendency to pull the piston rod out of the cylinder when the communication conduit is open; as well as drive means for opening and closing the communication conduit.
