Abstract
A floor care appliance or the like is provided with vibration isolating means for its motor-fan system which includes isolation at the agitator driving motor pulley which acts against belt tension.
Claims8
For use in a floor care appliance having a suction nozzle body in part enclosing a rotatable agitator, the structure including;
- (a) a vibration inducing motor-fan unit for creating a flow of air into said nozzle and having a projecting shaft,
- (b) a first belt trained over said shaft and extending to an intermediate pulley arrangement;
- (c) a second belt trained over said intermediate pulley and driving said rotatable agitator,
- (d) a means for vibrationally isolating said motor-fan unit from said body of said cleaner mounted in compression in line with one of said belts to provide vibration isolation of said motor-fan unit from said body at the belt end of said motor-fan unit.

For use in a floor care appliance having a nozzle, the structure including;
- (a) a vibration inducing motor-fan unit for creating a flow of air into said nozzle and having a projecting, overhanging shaft,
- (b) primary vibration isolating means at the center of gravity of said motor-fan unit and supporting the latter in a normal operating position upon said appliance while vibrationally isolating said appliance therefrom,
- (c) a belt trained about said overhanging shaft and under tension to exert a transverse force on said motor-fan unit tending to shift the latter from its normal operating position,
- (d) and secondary vibration isolating means opposing the tension of said belt and the transverse force exerted thereby on said motor-fan unit thereby opposing belt-induced shifting of said motor-fan unit from its normal operating position.
