US 6,719,085 B2 · Retractable ornament assembly for an exhaust pipe of a vehicle

Abstract

An ornament assembly for an exhaust pipe of a vehicle has a sleeve, an axle, a spring and a propeller. The sleeve is secured in an opening end of the exhaust pipe. The axle is moveably received in the sleeve. The axle has a first end exposed from the sleeve and a second and extending into the sleeve. The spring is received in the sleeve and is securely attached between the sleeve and the second end of axle. The propeller is rotatably mounted on the first end of the axle. Accordingly, the propeller will rotate when the waste gases are emitted from the exhaust pipe, and the axle will move relative to the sleeve. This can provide an excellent visual effect to the vehicle, and the appearance of the vehicle is improved.
