Abstract

Su ciascun montante (13) è fulcrata una coppia di piastre (32) dissipatrici di energia, le quali sono collegate ad un elemento sagomato di attacco (26) del corrente (10), mediante due giunture (38, 29; 38, 30) distanziate verticalmente. Queste comprendono un setto (38) atto ad essere tranciato a seguito di un urto, per dissiparne parte dell'energia. Le piastre 32 sono fulcrate su un perno (43) di una porzione rinforzata (19) del montante (13), e sono munite di asole curve (44) in impegno con un altro perno (47) di tale porzione, per consentire una rotazione delle piastre (32) e del corrente (10), in caso di deformazione del montante (13) verso l'esterno. I perni (43, 47) possono scorrere verticalmente verso l'alto su corrispondenti asole (21, 24) ricavate nel montante (13). I montanti (13) sono inoltre collegati da un nastro sagomato battiruota (48) e da una nervatura piatta posteriore (51), che nell'urto agisce da tirante.Figura 6A pair of energy-dissipating plates (32) are pivoted on each upright (13), which are connected to a shaped current connection element (26) (10), by means of two joints (38, 29; 38, 30) vertically spaced. These comprise a septum (38) adapted to be sheared following a collision, to dissipate part of its energy. The plates 32 are pivoted on a pin (43) of a reinforced portion (19) of the upright (13), and are provided with curved slots (44) in engagement with another pin (47) of this portion, to allow rotation of the plates (32) and of the batten (10), in case of deformation of the upright (13) towards the outside. The pins (43, 47) can slide vertically upwards on corresponding slots (21, 24) obtained in the upright (13). The uprights (13) are also connected by a shaped wheel-beating tape (48) and by a flat rear rib (51), which acts as a tie rod in the impact.
