Compactor

Abstract

A hand controlled compactor ( 1 ) for the compaction of ground work, paving etc comprises a base plate ( 2 ), carrying both a rotatable, out of balance mass ( 5 ) and a motor or engine ( 6 ), with a drive connected to the mass ( 5 ) to impart vibrations to the base plate ( 2 ), an operator's handle ( 22 ) also being provided, the motor or engine ( 6 ) being attached to the base ( 2 ) plate via a plurality of anti-vibration, shock-absorbing mountings ( 9 ). Another aspect provides for the operator's handle ( 22 ) to be attached to the compactor ( 1 ) via anti-vibration bushes ( 29 ) housed in a closed eye ( 28 ).

1 . A hand controlled compactor for the compaction of ground work, paving etc comprising:
 (i) a base plate having an underside adapted to engage the ground etc and to transmit compacting vibrations to the ground etc;   (ii) a rotatable, out of balance mass mounted on an upper side of said base plate;   (iii) a motor or engine attached to said base plate with a drive connected to said mass to impart vibrations to said base plate; and   (iii) an operator's handle,   characterised in that said motor or engine is attached to said base plate via a plurality of anti-vibration, shock-absorbing mountings.   
   
   
       2 . A compactor as claimed in  claim 1 , wherein each of said mountings is wholly or principally of rubber. 
   
   
       3 . A compactor as claimed in  claim 2 , wherein each of said mountings consists of an anti-vibration or shock-absorbing bush. 
   
   
       4 . A compactor as claimed in  claim 3 , wherein each said bush is cylindrical, and is adapted to be fitted on an upright axis. 
   
   
       5 . A compactor as claimed in  claim 3 , wherein each said bush has at least one embedded metallic threaded insert to receive a stem of a securing bolt. 
   
   
       6 . A compactor as claimed in  claim 5 , wherein two discrete, coaxial inserts are provided in each said bush. 
   
   
       7 . A compactor as claimed in  claim 1 , wherein said motor or engine is attached to said base plate via a mounting plate. 
   
   
       8 . A compactor as claimed  claim 1 , wherein said drive connection is a belt or chain. 
   
   
       9 . A hand controlled compactor for the compaction of ground work, paving etc comprising:
 (i) a base plate having an underside adapted to engage the ground etc and to transmit compacting vibrations to the ground etc;   (ii) a rotatable, out of balance mass mounted on an upper side of said base plate;   (iii) a motor or engine attached to said base plate with a drive connected to said mass to impart vibrations to said base plate; and   (iii) an operator's handle,   characterised in that an anti-vibration bush is housed in a closed eye in each of a pair of side arms of said compactor, and said operator's handle includes a portion extending transversely into said bushes.   
   
   
       10 . A compactor as claimed in  claim 9 , wherein said motor or engine is attached to a mounting plate, and said pair of side arms are also attached to said mounting plate and extended upwardly and rearwardly therefrom.
