Abstract
Abstract A cleaning device comprises a housing and a cleaning body. The cleaning body is mounted on a stub shaft which is glidingly arranged in a guide bore at one end of the housing and the guide bore and stub shaft extend in the working direction in which the cleaning body is pressed against an object to be cleaned. A driving system for driving the stub shaft and the cleaning body mounted thereon in an oscillatory manner includes a drive motor, a shaft axially extending from one of the motor ends, a flywheel mass mounted on the motor shaft for generating an oscillatory motion, a connection for transmitting the oscillatory motion to the stub shaft and a resilient mounting for the drive motor in the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A cleaning device comprising a housing having an axis and guide means at one end of the housing, a cleaning body to be pressed against an object to be cleaned in a working direction, a drive part glidingly arranged in the guide means, the cleaning body being mounted on the drive part and being driven thereby, and a driving system for driving the drive part and the cleaning body mounted thereon in an oscillatory manner, the driving system including a drive motor having an axis and two ends, a shaft axially extending from one one of the motor ends, a flywheel mass mounted on the motor shaft for generating an oscillatory motion, means for transmitting the oscillatory motion to the drive part, means mounting the drive motor in the housing for oscillation, the mounting means being arranged at one of the motor ends adjacent the drive part, and means for pivotally mounting the other end of the motor in the housing.
Claim 2
Dependent Claim
161 words
A cleaning device comprising a housing having an axis and guide means at one end of the housing, a cleaning body to be pressed against an object to be cleaned in a working direction, a drive part glidingly arranged in the guide means, the cleaning body being mounted on the drive part and being driven thereby, and a driving system for driving the drive part and the cleaning body mounted thereon in an oscillatory manner, the driving system including a drive motor having an axis and two ends, a shaft axially extending from one one of the motor ends, a flywheel mass mounted on the motor shaft for generating an oscillatory motion, means for transmitting the oscillatory motion to the drive part, means mounting the drive motor in the housing for oscillation, the mounting means being arranged at one of the motor ends adjacent the drive part, and means for pivotally mounting the other end of the motor in the housing.
Claim 3
Dependent Claim
23 words
The cleaning device of claim 1, wherein the housing, the guide means and the motor are coaxial and extend in the working direction.
Claim 4
Dependent Claim
58 words
The cleaning device of claim 1 or 2, wherein the drive part is arranged for replaceably carrying the cleaning body, the drive part being a stub shaft having an end of hexagonal cross section for receiving a correspondingly shaped bore in the cleaning body, and further comprising retaining means for holding the cleaning body on the drive part.
Claim 5
Dependent Claim
32 words
The cleaning device of claim 1, further comprising a receptacle for cleaning fluid mounted on the housing and conduit means for conducting the cleaning fluid from the receptacle to the cleaning body.
Claim 6
Dependent Claim
31 words
The cleaning device of claim 1, further comprising a hand grip on the housing for enabling the cleaning device to be manually held and pressed against the object to be cleaned.
