Definitions

  • the present disclosure provides a hand held fibrous duster. BACKGROUND
  • Cleaning of screen parts such as television screens, desktops, laptop screens and keyboards etc are conventionally performed by using cotton wipes, microfiber cloths and brushes provided with handheld structures or elongated handheld brushes with gripping portion.
  • the microfiber cloths usually provide cleaning by picking up the static dust due to electrostatic force.
  • the larger fiber clusters do not provide effective uniform pressure to clean small screens of mobile devices.
  • the brushes are generally used by moving the brushes multiple times over the cleaning surface of the screen. This will result in wiping of the dust from the effective surface in contact with the brush and the wiped dust gets accumulated around the corners and the edges of the screen. Further force applied on the handheld structures such as the handle of the brush gets translated into pressure which is unevenly or non-uniformly distributed over the surface of the screen in contact with the brush. Moreover, applying larger force may result in cracks, scratches or damage to the screen.
  • a flat duster has a planar cleaning surface as illustrated in Figure 1.
  • the flat duster is costly, difficult to store, and is intended for long term use.
  • the total force required to clean off the desired surface is more as whatever force is applied to collect the dust, gets distributed along the surface to be cleaned.
  • a flat duster moves it creates a swiped surface which is cleaned.
  • the surface formed by points 1 , 2, 3 and 4 represent the flat duster's cleaning surface.
  • the duster is moved to 1', 2', 3' and 4' creating cleaned surface 1 , 2, 3', 4.
  • line segment 1 and 2 would have been translated till 3' and 4' the same area betweenl , 2, 3', 4' would have been swept.
  • flat bed dusters cleaning ability is only equal to its longest cleaning edge. Significantly, even minor undulations on the flat cleaning surface result in uneven cleaning.
  • a typical brush can be described as shown in the figure 2.
  • a brush does not contain all the dust within itself and has a tendency of distributing the same in adjacent environment. Brushes also require more effort to dean a surface. If the brush bristles are rigid then there is always a possibility of scratching on sensitive surfaces by the pointed bristles' tips.
  • a cleaner described in Japanese patent document JP11225940 comprising of a cleaning fiber such as a super thin synthetic fiber or non woven cloth mixed with conductive fibers used on a roller surface to clean screen part surface of display devices.
  • a cleaning fiber such as a super thin synthetic fiber or non woven cloth mixed with conductive fibers used on a roller surface to clean screen part surface of display devices.
  • the point of contact of the cleaner and the surface to be cleaned has zero relative velocity in the direction of the movement of cleaner and hence does not provide enough friction to pick up the dust from the surface to be cleaned.
  • the rotating surface of the cleaner provides cleaning by picking up static dust due to electrostatic force and the cleaner is intended towards solving the problem of cleaning cathode ray electronic screens, which would gather substantial electrostatic charge on the surface.
  • the handle and pivot at only at one end of the duster makes the distribution of pressure along the roller surface uneven.
  • a fiber duster is therefore desired which provides effective cleaning not only due to dust pick up capabilities of the fiber but which also provides an uniform distribution of pressure on the cleaning surface such that the dust gets effectively removed from the surface in contact without damaging the surface of the screen.
  • Such fiber duster is desired which can economically fit between the thumb and fingers of the human hand to clean small and medium screen sizes. Further it is also a concern to design such fiber dusters which are easy and economic to manufacture with minimum complexity in design.
  • the hand held fibrous duster comprises of a base and a cleaning fabric.
  • the base defines at least one curved cleaning surface configured to hold a cleaning fabric thereon.
  • the said cleaning fabric is mounted on the cleaning surface and covers at least a portion of the cleaning surface, such that on sliding the duster against a surface, only a fraction of the cleaning fabric comes in contact with the surface, said fraction defining a cleaning edge that remains in contact with the surface.
  • Figure 1 illustrates a surface as cleaned by a prior ah flat duster.
  • Figure 2 illustrates a prior art brush.
  • Figure 3 illustrates a duster held at two side ends of the base of the duster in accordance with an embodiment of the invention.
  • Figure 4 illustrates a cleaning edge of the duster in accordance with an embodiment of the invention.
  • Figure 5 illustrates a magnet placed at two side ends of the base of the duster in accordance with an embodiment of the invention.
  • Figure 6 illustrates the dimensions of the base of the duster in accordance with an embodiment of the invention.
  • Figure 7 illustrates the slots and pins in the base of the duster in accordance with an embodiment of the invention.
  • Figure 8 illustrates an assembled cleaning fabric mounted on the base of the duster in accordance with an embodiment of the invention.
  • FIG. 9 illustrates the multiple layers of the cleaning fabric mounted on the base of the duster in accordance with an embodiment of the invention.
  • Figure 10 illustrates the cleaning surface of the duster in accordance with an embodiment of the invention.
  • a hand held fibrous duster is disclosed.
  • the hand held fibrous duster comprises of a base and a cleaning fabric.
  • the base defines at least one curved cleaning surface configured to hold the cleaning fabric thereon.
  • the cleaning fabric is mounted on the cleaning surface and covers at least a portion of the cleaning surface such that on sliding the duster against a surface, only a fraction of the cleaning fabric comes in contact with the surface, said fraction defines a cleaning edge that remains in contact with the surface.
  • the base of the hand held fibrous duster is a circular cylinder.
  • the entire outer surface can be considered as the cleaning surface.
  • An exemplary circular cylindrical shaped duster is shown in Figure 3.
  • Such duster is held at the two side ends of the duster as shown in Figure 3 and comprises of a base SL1 on which cleaning fabric FC is mounted.
  • the cleaning edge AB is formed by the line segment AB joining the points A and B of the duster touching the surface DEFG along the line with end points x1 and y1 on the surface DEFG.
  • the cleaning edge AB On sliding the duster against the surface DEFG, the cleaning edge AB reaches the line on the surface DEFG joined by the points x2 and y2 , the surface ( x1 ,y1 ,y2,x2) created by the translation of cleaning edge AB along the lines formed by ( x1 ,x2) and (y1 ,y2) is the cleaned surface.
  • the line that has gathered the dust is the cleaning edge AB.
  • AB is the cleaning edge for a single cleaning operation. The cleaning edges can be selected differently during each cleaning operation.
  • the force exerted by the user along the two side ends of the duster gets distributed along the line segment AB evenly.
  • the resultant pressure is more when compared to the cleaning devices which have a surface contact as shown in Figure 1.
  • the resultant force results in higher pressure along the line AB, it enables the duster to be held between two fingers and also generates enough friction to pick up dust particles by the cleaning fabric mounted on the cleaning surface of the duster.
  • the cleaning fabric is a fibrous coating.
  • the cleaning fabric FC is mounted over the base SL1.
  • the fibrous coating can be a microfiber fabric or similar fabric made of fibers of materials such as polyester, polyamide, nylon, cotton etc. or a non woven fabric. Artificial fur of different kinds can also be used.

  • cleaning fabric having density less than 1 denier may also be used.
  • the base is made of wood or any type of plastic such as polypropylene, polystyrene, polyvinylchloride, rubber etc or any such material that can provide necessary rigidity and base to hold the cleaning fabric FC1.
  • the base comprises of a magnet for affixing the fibrous duster to a metallic surface such as a writing board.
  • the magnet M1 can be placed at either one or both side ends of the base.
  • the magnet may be shaped as a ring as to provide space for holding articles such as pens, markers etc., or may have any other shape for aesthetic or functional purposes.
  • Figure 6 illustrates the dimensions of the base of the duster.
  • the length of the base can be made between 4 to 20 cm such that it fits in the human hand for easy handling.
  • the radius of the curved cleaning surface is made less than 4 cm.
