Emergency front door for pneumatically-propelled vehicles on an elevated track

An emergency front door for pneumatic propulsion on an elevated guideway comprising:

• a vehicle that moves along an elevated guideway that has segments with side guardrails fitted with emergency lights that are suitable for protecting and guiding users leaving the vehicle in an area outside a station, wherein the front door articulated in the structure of the vehicle on upper hinges assisted by dampers connected to an internal structure of the front door, and the structure of the frame of the vehicle, wherein the front door has a lower portion that moves on a lower hinge on the structure of the frame of the vehicle wherein it is automatically projected outwards by the action of pulleys and cables, with a retractable staircase that extends outwards when opening the lower portion of the door and, when retracted, is folded below the floor of the vehicle, and wherein the front door is activated internally using a lever that turns a that axially moves one or more shafts that release a door locking mechanism), wherein the retractable staircase that is positioned below the floor level of the vehicle (VP) when retracted, being comprised of retractable steps held together by articulated bars, remaining retracted and folded into the lower compartment when the front door is closed, with the articulated bars installed coaxially on the outer sides of the steps, having side panels that guide the retraction of the stairs, whereby when the front door is raised, the lower portion of the door is articulated, whereby the articulated bars pull on the side arms and cause the steps of the stairs to turn and automatically project outwards and downwards.
