<p>The device (1) has an operating mechanism (40) actuated from the exterior of an infrastructure and supporting a rigid pushing piece (30) against a bolt (9) until the piece releases an opening frame e.g. vertical door, for opening an emergency access. A chassis (20) supports the mechanism. The mechanism has a lock insert (42) driven in rotation under the action of a key when the key is received in the insert. A cam (52) is kinematically connected in rotation to the insert and translationally drives the piece with respect to the chassis along a rectilinear translation direction (T).</p> |
