| 摘要 |
A wringing device (1) for a wiper covering (20) on a flat wiper is disclosed, comprising a downwardly conically tapering, essentially funnel-shaped wringing shaft (2) with counter-pressure surfaces, whereby the wiper covering (20), on placing the wiper plate (10) in an essentially vertical position, is partly removed from the above and hangs down and may be introduced upwards and squeezed by pressure on the handle (30). The wiper plate (10) may also be partly introduced into the wringing shaft (2) for squeezing, such that the front face thereof, facing downwards, forms a squeezing surface. Said wringing device (1) comprises devices for stabilization of the wiper plate against tipping on introduction and squeezing of the wiper covering (20) in the wringing shaft (2). The invention further relates to a use of said wringing device and a cleaning system, comprising an advantageous combination of the above wringing device (1) with a flat wiper with a two-piece wiper plate (10) with plate wings (10 a, 10 b) which may be swung down and a looped wiper covering (20) hanging downwards. |
