Stabilization apparatus

1. A stabilization apparatus ( 1 ) for lifts, handlers and air platforms, comprising:

at least one main body ( 2 ), adapted to be assembled onto a vehicle, equipped with at least two lateral branches ( 21 ), at which respective first arms ( 11 ) are rotoidally coupled, the latter being hinged at the proximal ends thereof to distal ends of the corresponding branches ( 21 ) and second arms ( 12 ), each rotoidally coupled to a respective first arm ( 11 ), defining, together with said branches ( 21 ), relative articulated stabilizers ( 10 ), wherein said stabilizers ( 10 ) are movable between a retracted position in which said stabilizers ( 10 ) are folded onto themselves, and an extended position wherein said stabilizers ( 10 ) are unfolded, thus defining a stabilization position;

wherein the lateral branches ( 21 ) extend downwards;

wherein, in the retracted position of each stabilizer ( 10 ), the respective first arm ( 11 ) and the respective second arm ( 12 ) are arranged above the relative branch ( 21 ) of the main body ( 2 ), one alongside the other, together defining a vertical encumbrance substantially determined by the length of the respective first arm ( 11 ),

the main body ( 2 ) and the first and second arms ( 11 , 12 ) being sized such that the vertical encumbrance of the apparatus ( 1 ) in its entirety is equal to said length of the respective first arms ( 11 ), when in the retracted position thereof, whereas the side encumbrance of the apparatus ( 1 ) is substantially equal to that of the main body ( 2 ).

2. The apparatus ( 1 ) according to claim 1 , comprising actuating means ( 3 ) adapted to push the stabilizers ( 10 ) into said stabilization position.

3. The apparatus ( 1 ) according to claim 2 , wherein said actuating means ( 3 ) include, for each stabilizer ( 10 ), an actuator ( 3 ) adapted alternatively to push outwards or pull inwards said first arm ( 11 ).

4. The apparatus ( 1 ) according to claim 1 , comprising opening means ( 40 , 41 , 42 ) to automatically unfold each stabilizer ( 10 ) that is moved into the respective stabilization position.

5. The apparatus ( 1 ) according to claim 1 , comprising closing means to automatically fold each stabilizer ( 10 ) onto itself which is moved into the respective retracted position.

6. A stabilization system for a vehicle of the type used in lifts, handlers or air platforms, comprising at least two apparatuses ( 1 ) according to claim 1 , fixed to longitudinal ends of a support bridge.

7. A stabilization apparatus ( 1 ) for lifts, handlers and air platforms, comprising at least one main body ( 2 ), adapted to be assembled onto a vehicle, equipped with at least two lateral branches ( 21 ), at which respective first arms ( 11 ) are rotoidally coupled, characterised in that the apparatus ( 1 ) further comprises second arms ( 12 ), each rotoidally coupled to a respective first arm ( 11 ), defining, together with said branches ( 21 ), relative articulated stabilizers ( 10 ), wherein said stabilizers ( 10 ) are movable between a retracted position in which said stabilizers ( 10 ) are folded onto themselves, and an extended position wherein said stabilizers ( 10 ) are unfolded, thus defining a stabilization position, the apparatus further comprising, for each stabilizer ( 10 ), at least one traction organ ( 40 , 41 ) comprising a first end connected to said main body and a second end connected to said second arm ( 12 ).

8. The apparatus ( 1 ) according to claim 7 , wherein said traction organ comprises a flexible and inextensible element ( 40 ).

9. The apparatus ( 1 ) according to claim 8 , comprising opening means ( 40 , 41 , 42 ) to automatically unfold each stabilizer ( 10 ) that is moved into the respective stabilization position, wherein said opening means ( 40 , 41 , 42 ) comprise for each stabilizer ( 10 ), at least one tension element ( 42 ) above which said flexible and inextensible element ( 40 ) can slide, to allow, following a thrust outwards of the first arm ( 11 ), the second arm ( 12 ) to be dragged in rotation upwards, hence unfolding the stabilizer ( 10 ) while the stabilizer ( 10 ) is brought into the aforementioned extended position.

10. The apparatus ( 1 ) according to claim 9 , wherein a tension element ( 42 ) is arranged at the rotoidal coupling between the first arm ( 11 ) and the second arm ( 12 ).

11. The apparatus ( 1 ) according to claim 9 , wherein a tension element ( 42 ) is arranged at the rotoidal coupling between said branch ( 21 ) and said first arm ( 11 ).

12. The apparatus ( 1 ) according to claim 8 , comprising closing means to automatically fold each stabilizer ( 10 ) onto itself which is moved into the respective retracted position, wherein said closing means comprise, for each stabilizer ( 10 ), at least one tension element below which said flexible and inextensible element ( 40 ) can slide, to allow, following a thrust inwards of the first arm ( 11 ), the second arm ( 12 ) to be dragged in rotation downwards, hence folding the stabilizer ( 10 ) onto itself while the stabilizer ( 10 ) is brought into the aforementioned retracted position.

13. The apparatus ( 1 ) according to claim 12 , wherein a tension element ( 42 ) is arranged at the rotoidal coupling between the first arm ( 11 ) and the second arm ( 12 ).

14. The apparatus ( 1 ) according to claim 7 , wherein said traction organ ( 40 , 41 ) includes, at said first end, an elastic return means ( 41 ) fixed to said branch ( 21 ).
