Barrier Release Mechanism

摘要

A barrier release mechanism for a construction including a barrier and frame has a latch biased towards an unlatching position. An actuation device adjacent the construction is movable, under pressure from a fluid pressure source, into an engaged position in abutment with the latch to urge the latch against the bias to cause constraining of the barrier. Reduction of the pressure allows the actuation device to move to a disengaged position wherein the bias moves the latch to the unlatching position in which the barrier is not constrained.
