Abstract

The present invention relates to a replaceable fabric coating (1) for floor wet cleaning brushes comprising a plate-like element (2) including a fabric layer (3) bearing, on a surface thereof, a plurality of piles or threads (4) and, on another surface thereof, a plastic material binding layer (10).

On the plate-like element, at the binding layer side, is superimposed an absorbing material layer (20) which defines opposite pockets (21) for coupling to a frame for tensioning and supporting the plate-like element.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a replaceable fabric coating for floor wet cleaning brushes and the like.
As is known, are commercially available apparatus for wet cleaning floors, which comprise a cleaning brush, of large size, on which is applied a replaceable coating.
In prior wet washing brushes are conventionally used coating assemblies including a fabric layer which, on a face thereof is provided with a plurality of piles and, on the other face thereof, having a plastic material binding layer.
The latter is usually of an impermeable type.
In order to stiffness this coating fabric, the edge portions thereof are up-turned so as to be superimposed on the rear face or surface, and so as to provide an up-turned portion which, practically extends through the overall periphery of the fabric.
Such a solutions has not been found fully satisfactory, since the application of a fully impermeable layer does not properly adjust the moisture which must be present at the pile region, in order to properly clean the floors and the like.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to solve the above mentioned problem, by providing a replaceable fabric coating for floor wet cleaning brushes, which affords the possibility of easily and quickly adjusting the moisture at the pile or thread region thereof, so as to provide a layer able to operate as a liquid "tank" to always provide an optimum desired moisture degree.
Within the scope of the above mentioned aim, a main object of the present invention is to provide such a replaceable fabric coating which is very simple construction-wise and which, in particular, does not require that up-turned portions be made on the pile provided face of the fabric.
Another object of the present invention is to provide such a replaceable fabric coating which, owing to its construction features, is very reliable and safe in operation.
Yet another object of the present invention is to provide such a replaceable fabric coating for floor wet cleaning brushes, which can be easily made starting from easily commercially available materials and which, moreover, is very competitive from a mere economic standpoint.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a replaceable fabric coating for floor wet cleaning brushes, characterized in that said coating comprises a plate-like element having a fabric layer including, on a face thereof, a plurality of piles or threads and, on the other face thereof, a plastic material binding layer.
On the aforesaid plate-like element is superimposed an absorbing material layer, defining opposite pockets for connection to a frame for tensioning and supporting said plate-like element.

BRIEF DESCRIPTION OF THE DRAWINGS

Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a replaceable fabric coating for floor wet cleaning brushes, which is illustrated, by way of an indicative, but not limitative example, in the accompanying drawings, where:

Figure 1 is an exploded perspective view illustrating the replaceable coating according to the present invention;
Figure 2 illustrates the coating according to the present invention as seen from the rear face or surface thereof;
Figure 3 is s cross-sectional view substantially taken along the line III-III od Figure 2;
Figure 4 is a further schematic view illustrating the replaceable coating according to the invention as applied to a brush.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures, the replaceable fabric coating for floor wet cleaning brushes according to the present invention, which has been generally indicated by the reference number 1, comprises a plate-like element 2, which includes a fabric layer 3, having, on a face thereof, a plurality of piles 4 which are evenly distributed.
The plate-like element 2 has a normally elongated configuration, so as to be fitted to the coupling frame 5 to be connected to a cleaning brush, generally indicated by the reference number 6.
On the face of the fabric layer 3 opposite to that having the piles or threads 4, is provided a plastic material binding layer 10, operating for binding and connecting to one another the warp and weft threads or yarns of the layer 3, so as to provide a supporting layer for the plate-like element.
The plastic material layer is advantageously made of a porous plastic material and, if desired, throughgoing holes 11 or throughgoing spots 12 are provided therethrough, the function of which will become more apparent hereinafter.
To the plate-like element 2, which is made in a flat shape without any up-turned portions, is coupled an absorbing material layer, indicated by the reference number 20, which can be made of a not-woven fabric material, of a foamed plastic material, for example of the open cell type, or of any other materials suitable to properly absorb the moisture.
The layer 20 is coupled to the plate-like element 2 by means of seaming stitches or by glueing, or any other coupling methods suitable to stably connect the two superimposed elements.
The layer 20, defines, at opposite positions, a pair of pockets 21 for coupling with the end portion of the frame 5 of the brush 6.
The provision of the at least partially absorbing material layer is very important, since it will allow to absorb the excess liquid on the piles 4, with the consequent possibility of releasing said liquid, through the throughgoing holes 11 and/or the seaming stitches 12 as the moisture degree decreases under said values.
Thus, in actual practice, this layer of an at least partially absorbing material, in addition to stiffen the replaceable coating, will provide the very important function of always hold a desired moisture degree.
From the above it should be apparent that the invention fully achieves the intended aim and objects and, in particular, the fact is to be pointed out that a replaceable coating has been provided which is very simple from the construction standpoint, since in said coating are simply mutually superimposed the plate-like element which does not include any folded portions, and the partially absorbing material layer which, in addition to operating as a moisture adjusting member, is also adapted to properly stiffen the coating.
In this connection it should be furthermore pointed out that the replaceable coating 1 according to the present invention comprises a fabric layer 3 having on a face thereof a plurality of piles or threads 4 and, on the other face thereof, a binding layer 10, seamed to a stiffening and reinforcement material layer, made of a not woven fabric 20, which is associated with the first on the overall surface thereof.
The subject replaceable coating, as seen from the top, has a rectangular or substantially rectangular configuration, with a removal of material at the corners thereof, which, as needed, can be suitably rounded.
In practicing the invention, the used materials, provided that they are compatible to the intended use, as well as the contingent size and shapes, can be any, depending on requirements.
