Rescue tool e.g. hatchet, for operating rescue access safety device, has cam kinematically connected in rotation to lock barrel and for driving force part in translation with respect to chassis along straight translation direction

摘要

The tool has a rigid chassis (20) for supporting a control mechanism and fixedly integrated with a wythe or floor determining a rescue access. The control mechanism comprises a lock barrel to be driven in rotation on itself under an action of a key (44) that is suitable to the barrel when the key is received in the barrel. A cam is kinematically connected in rotation to the barrel and for driving a driving force part in translation with respect to the chassis along a straight translation direction.
