  • a braking system presents a risk for the user, especially when the latter does not control the braking, and in particular the movement of his leg actuating said second portion of the rod which acts on said braking system. The stability of the user is then not optimal, it can tilt forward; therefore, there is a risk of falling.

  • the braking element 21 is implemented by means of a braking roller as illustrated in FIGS. Figures 1 to 4 .
  • the rotary movement of the roller has the advantage of friction between two moving parts which allows progressive braking unlike the friction between a fixed part and a moving part that can generate a risk of blockage of the system and, consequently, shots.
  • This braking roller 21c, 21d preferably comprises a profile which is arranged to have at least two contact points 101, 103 with the wheel 5c, 5d, these contact points 101, 103 being situated at radii having a different length. relative to each other as illustrated in an example in FIG. 6.
  • two points of contact are provided between the wheel and the roller causing speeds at the two points of contact between the rollers and the different wheel, having effect of generating friction directly between the roller and the wheel, without the need to use an additional braking element acting on said roller 21 to brake it and reflect said braking on the wheels, the latter solution however still possible with the use of a traditional pebble.
  • said braking roller 21a, 21b, 21c, 21d by another braking element 21 of the fixed braking shoe type on the movable part 25, said pad preferably having a suitable circular shape the shape and radius of the wheels of the roller.
  • the pusher of the triggering device 29 is implemented by means of a rod 31 actuated under the effect of the actuating device 28 and for driving the movement of the trigger piece 33. It would be however, it is possible to design a pusher of electronic and / or magnetic type remotely actuated by the actuating device 28, for example of the control box type, the remote triggering of said pusher enabling said pusher to act on the piece of tripping 33 to move it in the locking position of the movable part 27 and the fixed part 25, or conversely of unlocking said parts.
  • This pusher may further consist of the combination of a servomechanism or a jack, associated with a connecting rod, the servomechanism or jack being actuated by a control button.
  • the braking pad comprises blocking means of the pad in the slipping position ensuring the spaced apart position of the pad between the fixed part 25 and the movable part 27, these locking means being able for example to consist of a locking latch forming a stop on the piece triggering 33 so as to prevent the activation thereof and to maintain the skating position.
  • Such locking means have a remarkable advantage when the pad is used in extreme conditions, for example for the realization of figures or acrobatics; they allow to occasionally block the pad for such use, the user having than to neutralize said locking means when it wishes to be able to use the braking system again.
