CompactorCompactor description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090035065, Compactor. Brief Patent Description - Full Patent Description - Patent Application Claims
This Application claims the benefit of British Application Serial No. 0715013.9 filed Aug. 2, 2007. FIELD OF THE INVENTIONThis invention relates to a manually controlled compactor for the compaction of ground work, earth work, landfill, paving etc. BACKGROUND OF THE INVENTIONManually controlled compactors are known comprising basically an internal combustion engine to drive an eccentric to create the necessary vibrations with the engine attached to a base plate for the transmission of those vibrations to the base plate and thereafter to the earth work etc, with an operator's handle adapted to manoeuvre the compactor as required. It follows that vibrations are transmitted back from the base plate through the engine to the operator's handle and with a view to avoiding or reducing the propensity for an operator to suffer HAVS, rubber hand grips are conventionally provided on the operator's handle. OBJECT OF THE INVENTIONA basic object of the invention is the provision of an improved compactor for paving etc. SUMMARY OF A FIRST ASPECT OF THE INVENTIONAccording to a first aspect of the present invention, there is provided 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 the base plate; (iii) a motor or engine attached to the base plate with a drive connected to the mass to impart vibrations to the base plate; and (iv) an operator's handle characterised in that the motor or engine is attached to the base plate via a plurality of anti-vibration, shock-absorbing mountings. ADVANTAGE OF THE INVENTIONThe imposition of such mountings between the motor/engine and the base plate as a means of attaching these two components together substantially reduces the vibrations transmitted back from the base plate through the motor/engine to the operator's handle. PREFERRED OF OPTIONAL FEATURESEach mounting is wholly or principally of rubber. Each mounting consists of an anti-vibration, shock-absorbing bush. Each bush is cylindrical, and is adapted to be fitted on an upright axis. Each bush has at least one embedded metallic threaded insert to receive the stem of a securing bolt.
