Joint protector

Abstract

A joint protector includes an elastic sleeve, which has a first opening and a second opening through which the sleeve is mountable on a limb of a person, and a lighting unit fastened to an outside wall of the sleeve for giving off light to show the presence of the joint protector.

1 . A joint protector comprising: 
 a sleeve made of an elastic material, said sleeve having a first opening and a second opening; and    a lighting unit fastened to said sleeve, said lighting unit including a circuit board, at least one light emitting element, and a battery, said circuit board having a control circuit, said at least one light emitting element being mounted on said circuit board and electrically connected to said control circuit, said battery being installed in said circuit board and electrically connected to said control circuit for providing electricity to said at least one light emitting element subject to the control of said control circuit.    
     
     
         2 . The joint protector as claimed in  claim 1 , wherein said at least one light emitting element includes three light emitting diodes.  
     
     
         3 . The joint protector as claimed in  claim 1 , wherein said circuit board comprises a control switch for controlling the supply of electricity from said battery to said at least one light emitting element.  
     
     
         4 . The joint protector as claimed in  claim 3 , wherein said control switch is a vibration switch which is actuated by vibration.  
     
     
         5 . The joint protector as claimed in  claim 3 , wherein said control switch is a manual switch.  
     
     
         6 . The joint protector as claimed in  claim 4 , wherein said vibration switch is a mercury switch.  
     
     
         7 . The joint protector as claimed in  claim 1 , wherein said sleeve further has a third opening through the inside and outside of said sleeve; said lighting unit further comprises a shield made of a flexible light-transmittable material, said shield having a front wall marked with a warning sign, a back wall, an accommodating chamber that accommodates said circuit board, an opening formed in said back wall in communication between said accommodating chamber and said third opening of said sleeve, and a flange extending around said back wall and bonded to said sleeve around said third opening with a glue.
