Improved Duster Flat Support

Abstract

This is an improved cleaning tool, called a duster, whose offset hinging can rotate around an axis to shift its footprint outside the position of the cleaning surfaces.

AI Technical Summary

Benefits of technology

The invention is a duster that can clean large surfaces without scratching them. It can also ensure the use of the cloth on both main and opposite surfaces of the plate. The duster is easy to adjust the inclination and works without interfering beyond the position of the active surface of the plate. The interconnecting devices allow the cleaning surface to be continuous and without discontinuity for the support of the cloth. The retention device facilitates the correct extraction sideshift movement, the relative rotation, and the subsequent insertion and repositioning movement of the insert into its seat.

Problems solved by technology

With respect to what is stated in the aforesaid patent, the duster has the drawback that the thickness of the adjustable hinge of the inclination between the handle and the laminar plate is greater than the thickness of the plate and protrudes beyond the position of the dusting surface.

This aforesaid positioning of the adjustable hinge with an axis corresponding to that of the plate entails, in fact, a considerable limitation to the use of said device, which cannot work freely on surfaces extending beyond the extension of the plate without the peripheral part of the adjustable hinge scraping along the floor.

There would be a possible solution in decreasing the diametric extension of the hinge, bringing its thickness within the overall dimensions of the plate, in this way compromising the reliability of the device for a unit load on the materials beyond their breaking strength.

Or, alternatively, another possible solution would be to increase the thickness of the plate beyond the maximum overall size of the hinge, in this way losing portability and the ease of movement of the manual cleaning tool.

Alternatively, it is possible to redesign the cleaning tool to overcome this problem by moving the adjustable hinge to one side so that it does not protrude beyond the dusting surface, however this introduces a further limitation of this cleaning tool, limiting the free dusting to just one side and using only half of the surface of the cloth that covers the duster.

For all the aforementioned reasons, this cleaning tool has met with little success to date, even if there is great demand for a tool that can remove dust on large surfaces without the risk of scratching.
