发明名称 Cleaning apparatus, particularly for cleaning window panes
摘要 A cleaning apparatus, particularly for cleaning window panes, is fitted with a replaceable strip-shaped rubber wiping element, a U-section holding sheath accommodating the rear edge of the wiping element and, at the forward end of a handle for holding the cleaning apparatus, two clamping plates of which one is detachable and secures the wiping element in its holding sheath. The detachable clamping plate is formed at its transverse front edge with an inwardly angled tapering lip which engages between one side of the holding sheath and the wiping element, and which is provided on its outside flank with rib-like teeth extending transversely to the longitudinal axis of the lip.
