Tail pipe for muffler

Abstract

A tail pipe includes a hollow body, two external fittings and an optional illuminating assembly. The hollow body has an outer periphery on which each external fitting is mounted. Each external fitting has a side face that faces outward from the body and a protrusion formed with a given shape and extending from the side face. The illuminating assembly is mounted in the body and has two arms extended out of the body and having multiple illuminating members to illuminate the external fittings to be visible in a dark place. Therefore, the external fittings provide a decoration for the tail pipe to make that to look more attractive. Also, the external fittings provide a visible signal to alert someone who is near the tail pipe to keep a distance from the tail pipe to avoid getting burned by the hot tail pipe.

1 . A tail pipe for a muffler having an exhaust pipe and comprising: 
 a hollow body having a front, a rear, an outer periphery and an inner passage having an inner periphery, a front opening and a rear opening that are formed respectively in the front and the rear of the body; and    at least one external fitting mounted on the outer periphery of the body and each of the at least one external fitting having a side face that faces outward from the body and a protrusion formed from the side face, and the protrusion having a shape.    
   
   
       2 . The tail pipe for the muffler as claimed in  claim 1 , wherein each of the at least one external fitting is light-transmittable and the tail pipe further comprising an illuminating assembly to illuminate each of the at least one external fitting, and the illuminating assembly comprises 
 multiple mounting brackets respectively attached to the inner periphery of the body;    a circuit board mounted on the mounting brackets and having an extended arm corresponding to each respective one of the at least one external fitting extending out of the body; and    multiple illuminating members mounted respectively on each extended arm and connecting electrically to the circuit board and facing the corresponding one of the at least one external fitting to make the corresponding external fitting being luminous.    
   
   
       3 . The tail pipe for the muffler as claimed in  claim 2 , wherein the illuminating members are light emitting diodes.  
   
   
       4 . The tail pipe for the muffler as claimed in  claim 3 , wherein the mounting brackets are L-shaped, and the circuit board further is ring-shaped with a central through hole.  
   
   
       5 . The tail pipe for the muffler as claimed in  claim 4 , wherein the body further has two mounting holes defined through the outer periphery to mount the tail pipe on the exhaust pipe of the muffler with fasteners.  
   
   
       6 . The tail pipe for the muffler as claimed in  claim 5  further comprising an inner pipe mounted in the inner passage of the body, having a front opening and a rear opening and held in the central through hole of the circuit board and suspended by means of fasteners, and the rear opening of the inner pipe connecting to the exhaust pipe.
