ABSTRACT:
An exhaust fumes distribution system for use within a structure adjacent to a space in which a vehicle having an engine coupled to a vertically oriented, open ended, exhaust stack is to be located to discharge exhaust fumes out of the structure. The system comprises an actuatable blower, an elongated guide tube, a collapsible conduit, and a wireless transmitter and receiver. The guide tube has a hollow interior and a slot extending therealong and is mounted horizontally above the space so that the slot extends from a first position adjacent an entrance to the structure to a second, remote position. The collapsible conduit is located within the guide tube and is coupled to the blower. The conduit has an end portion including an inlet opening and is biased into an extended position within the guide tube so that the inlet opening is located adjacent the first position to receive the open end of the stack through the slot. The conduit is collapsible so that the open end of the stack remains within the inlet opening in the conduit when the vehicle is moved in the structure from the first position to the second position. The wireless transmitter is arranged for actuating the receiver, which is coupled to the blower, so that upon operation of the vehicle's ignition switch the blower is actuated to vent fumes in the stack through the conduit and out of the structure.
