Abstract
An exhaust recovery system to vent exhaust from an exhaust pipe of a vehicle within a building. A coupling is detachably connectable to the exhaust pipe of the vehicle. An elongate flexible hose is interconnected between the coupling and a telescoping assembly. The telescoping assembly includes a plurality of tubular members slidably engaged within one another. As the vehicle is moved away from the telescoping assembly it causes the tubular members to slide with respect to one another permitting the vehicle to exit the building while exhaust from the vehicle passes through the hose and the telescoping assembly.
Claims10
An exhaust recovery system to vent exhaust from an exhaust pipe of a vehicle, located in an enclosed structure, as the vehicle is driven out of the structure, comprising:
- (a) a coupling detachably connectable to the vehicle exhaust pipe;
- (b) an elongate flexible hose having a first end and a second end, said first end of said hose connected to said coupling;
- (c) a telescoping assembly including a plurality of elongate tubular members which includes at least a first tubular member and a second tubular member slidably engaged within one another;
- (d) said second end of said hose connected to one of said tubular members;
- and
- (e) a tube supporting assembly separating an exterior surface of said first tubular member and an interior surface of said second tubular member from each other leaving an air gap therebetween substantially completely surrounding said first tubular member along a major portion of its length, said assembly including spacing elements interposed in said air gaps between said exterior surface of said first tubular member and said interior surface of said second tubular member, said spacing elements movably engaging at least one of said exterior surface and said interior surface.
