Vibration reducing link for vibrating screed

Abstract

A vibrating screed for surfacing concrete includes a surfacing blade, a vibration-causing assembly, a steering assembly with a handle assembly and a grip member in communication with the hand assembly. A vibration reducing link is disposed between the grip member and the handle assembly so that when the vibration-causing assembly imparts a vibratory motion to the blade and the handle assembly, the vibration reducing link dampens the vibratory motion transmitted between the handle assembly and the grip member.

1 . A vibrating screed comprising:
 a surfacing blade;   a vibration-causing assembly in communication with said surfacing blade;   a steering assembly in communication with said surfacing blade, said steering assembly comprising a handle assembly;   a grip member in communication with said handle assembly; and   a vibration reducing link disposed between said grip member and said handle assembly;   
       wherein when said vibration-causing assembly imparts a vibratory motion to said blade and said handle assembly, said vibration reducing link dampens said vibratory motion transmitted between said handle assembly and said grip member. 
     
     
         2 . The vibrating screed according to  claim 1 , wherein said vibration reducing link comprises:
 a first member in communication with said handle assembly;   a vibration reducing coupling disposed circumferentially about said first member;   a second member in communication with said grip, said second member receiving said vibration reducing coupling and said first tubular member; and   a clamp for securing said first tubular members and said vibration reducing coupling within said second tubular members when received therein;   
       wherein said vibration reducing coupling dampens vibration transmitted between said first and second members. 
     
     
         3 . The vibrating screed according to  claim 2 , wherein said vibration reducing coupling is disposed circumferentially within said second member, said first member received within said vibration reducing coupling and said second member. 
     
     
         4 . The vibrating screed according to  claim 2 , wherein said first and second members are tubular. 
     
     
         5 . The vibrating screed according to  claim 2 , wherein said first member and said vibration reducing coupling are rotatable within said second member. 
     
     
         6 . The vibrating screed according to  claim 3 , wherein said first member is rotatable within said vibration reducing coupling and said second member. 
     
     
         7 . The vibrating screed according to  claim 2 , wherein said vibration reducing coupling has a non-elastomeric layer disposed circumferentially about said vibration reducing coupling. 
     
     
         8 . The vibrating screed according to  claim 3 , wherein said vibration reducing coupling has a non-elastomeric layer disposed circumferentially about said vibration reducing coupling. 
     
     
         9 . The vibrating screed according to  claim 2 , wherein said vibration reducing coupling is made of an elastomeric material. 
     
     
         10 . The vibrating screed according to  claim 9 , wherein said elastomeric material is rubber. 
     
     
         11 . The vibrating screed according to  claim 2 , wherein said first member in substantially perpendicular in communication to said handle assembly, said second member is substantially perpendicular in communication to said first member; 
     
     
         12 . The vibrating screed according to  claim 2 , wherein said clamp is circumferentially disposed about the second member.
