Abstract (en)
[origin: EP0584049A1] The barrier (3, 22) is pivoted on a supporting body (9) by means of two separated coaxial vertical pins (26, 28); the axial displacement of the barrier with respect to the said pins (26, 28) and its release from them are prevented by a bolt (10) which is disengaged at the moment of an initial angular yielding of the barrier about the said pins (26, 28), so that the barrier (3, 22) is released axially from the two vertical pins (26, 28); the barrier (3, 22) and the said supporting body (9) form fork-shaped arms (9A, 9B; 22A, 22B) which interact with each other, with the vertical pins (26, 28), and with the bolt (10). <IMAGE>
