Heat shield for an exhaust tail pipe

For use in a motor vehicle having an internal combustion engine and a body which is spaced from a road surface on which said vehicle stands, a combination comprising:

• a cylindrical exhaust tube mounted in use beneath a body of a vehicle to allow the exhaust gases from an internal combustion engine to pass therethrough;
• a rectangular heat shielding plate of lesser axial length than said tube provided with a longitudinally extending concave recess having at opposite lateral sides of said concave recess respective step portions extending along the length of the concave recess, the concave recess having a semicircular cross section the radius of which is larger than that of an outer cylindrical surface of said exhaust tube;
• at least two axially spaced bridge members each having longitudinal ends respectively connected to said step portions and a middle portion transversely spanning said concave recess, said middle portion being bent toward a bottom of said concave recess to form a round section on which said exhaust tube is disposed in frictional contact therewith, the radius of said round section being smaller than that of said concave recess thereby to define a semicylindrical space between a surface of said heat shielding plate, defining said concave recess and an outer surface of said bridge member whereby a certain semicylindrical air space is defined between said surface of said concave recess and an outer surface of said exhaust tube;
• and
• at least two axially spaced bracket members each having longitudinal ends respectively connected to said step portions of said heat shielding plate and a middle portion covering said exhaust tube and in frictional contact therewith to attach said heat shielding plate to said exhaust tube in such a manner that the bottom of said concave recess is located between said exhaust tube and a road surface when said heat shielding plate is mounted on said exhaust tube and such that said heat shielding plate may move axially relative to said tube.
