Cleaning cloth for a base for mops with tabs

Abstract

A cleaning cloth has on each of its transverse sides a tab designed to be automatically connected to and retained by a coupling device on a mop base.

1 . A cleaning cloth for a mop base with tabs on transverse sides that can automatically connect to the coupling devices of the mop base placed at transverse ends of said base, where each coupling device is configured with an inlet mouth for the entrance of the end of the cloth, which is normally closed by elastic devices on the coupling device, wherein each of the two transverse ends of the cloth comprises a tab, which is configured with a profile that has an increasing cross-section, starting from a free end, and is able to open wide said inlet, while, with an insertion movement, it enters the mouth opening it wide with an extension at least equal to a maximum thickness of the increasing cross-section, and a sectional profile of said tab, after the maximum thickness, decreases with a steep front of the decreasing profile that is orthogonal to said movement for inserting said tab inside said inlet, said decreasing profile joins to the profile of an internal wall for retaining the coupling device, after the inlet has closed on a connecting lamina of the increased section with the cloth. 
     
     
         2 . The cleaning cloth of  claim 1  wherein said profile with an increasing section extends only towards a movable opening side of the inlet mouth on which the elastic devices for holding the cleaning cloth act. 
     
     
         3 . The cleaning cloth, of  claim 1  wherein said profile with an increasing section extends on both sides of the tab with a symmetrical profile. 
     
     
         4 . The cleaning cloth of  claim 1  wherein said decreasing profile of the tab, has a profile that curves inwards and pointing towards the free end of the tab. 
     
     
         5 . The cleaning cloth of  claim 4  wherein the profile of the internal retaining wall of the mouth is complementary to the inwardly curved profile to which it joins even more with each effort to extract the cloth. 
     
     
         6 . The cleaning cloth of  claim 5  wherein in combination with or taking the place of the increasing section profile of the tab, the front wall of the inlet is shaped with a tapered inclined plane towards a seat to receive and/or work together with the free end of the tab opening wide the inlet following the insertion of the tab through the inlet until it is completely inserted within the seat.
