ABSTRACT:
An emergency exhaust system is couplable to a vehicle for conducting exhaust fumes from the vehicle exhaust pipe to an enclosure ventilation system to be exhausted from the vehicle enclosure when the vehicle is normally parked when not being used. The exhaust system includes an elongated flexible hose assembly that is connected to the ventilation system and to an adaptor conduit which at its terminal end has a ring mounting electromagnets for magnetically attaching to a mount plate dependingly secured to the vehicle to have the vehicle exhaust pipe extend therethrough. An intermediate portion of the hose assembly is connected through a balancer assembly to a trolley movable along a rail in a forward direction as the vehicle moves to exit the enclosure. As the trolley moves adjacent to the rail front end, through automatic controls, the magnetic coupling to the mount plate is disengaged. As a result of not coupling directly to the exhaust pipe, the chances of damaging the vehicle exhaust system are minimized, but provision is made for safely conducting the vehicle exhaust fumes outside of the enclosure.
