Definitions

  • the invention relates to flexible cleaning body in shape of a cuboid, in the area of its bottom by a Abrasion area is limited.
  • Such a cleaning body is, for example known from EP-A-600829.
  • Cleaning bodies of the type mentioned arrive in the household to use. They are essentially brick-shaped Shape, made of foam and dimensioned so that holding on while performing cleaning operations is possible with one hand.
  • the cleaning body is usually in the area of the two side surfaces gripped with one hand and in the area of an end face touched with the index finger.
  • Grip grooves that extend parallel to the longitudinal direction should ensure that the flexible Material existing cleaning body during the implementation not inadvertently from cleaning processes of the receiving hand slips away. Due to the large volume of the part of the flexible cleaning body located in the palm of the hand it only works very unsatisfactorily because it is strong Compression of the cleaning body is also an impairment the shape of the abrasive surface and a Reduction of the remaining absorbency. The cleaning difficult to access corners and fillets is with the known Cleaning body difficult.
  • the invention has for its object such a cleaning body to develop in such a way that difficult to access Fillets and corners are easier to clean and that a better one while avoiding a cramped hand position Fixing the cleaning body in the receiving hand results.
  • the shape of the cleaning body is relatively simple can be generated. It nevertheless requires an approximation to itself anatomical form of the gripping movement human hand.
  • the cleaning body during the intended Experience the use of defined contact zones thereby a significant enlargement, which is certainty improves and avoids that a cramped Hand position results.
  • Deformation of the abrasion surface results. Avoiding from selective overloading of the flexible material existing cleaning body or the human hand thereby achieving a particularly good definition in a convenient manner.
  • the cleaning body can be made from any one or more of the relevant materials used to be generated, for example from a flexible block of textile and / or foam. If several materials come together in combination Application, for example a layer of polyurethane foam and a layer of a textile material, then the individual layers non-detachably or releasably attached to each other his. In the latter case it is possible, for example, to use Velcro in this regard.
  • the side and end faces delimiting the cuboid on two each other diagonally opposite ends through the inclined surface are connected and mutually at the other ends in the limit sharp edge.
  • the side surfaces can be in a manner known per se Grip grooves extending parallel to the longitudinal direction be, for example with a grip groove that is sinusoidal Profile is rounded and in the top of the cleaning body transforms.
  • the Inclined surface forms part of a rounding. This can evenly in the respective front and side surface leak, which is the usability when wiping fillets further improved and cleaning pots and kitchen ware simplified.
  • the rounding off is one Radius that is 0.2 to 0.5 times as large as that Width of the cuboid, preferably 0.3 to 0.4 times as large.
  • the thumb especially with such training harmonious in the area of rounding off the cleaning body put on what gives it a firm hold.
  • the bottom is used in many cases to to loosen adherent dirt components mechanically.
  • a directly adjacent side surface to be able to clean at the same time for example the side wall a pot in the area of the bottom, it has proven to be proven advantageous if the profile of the cleaning body in this area is sharply delimited.
  • Fig. 1 shows a first embodiment of the cleaning body in a perspective view from above.
  • Fig. 2 to 5 alternative versions of the cleaning body in a top view.
  • the cleaning body shown in FIG. 1 consists of a foam block made of open-pore polyurethane foam with a density of 30 to 40 kg / m 3 , preferably of 35 kg / m 3 . It has the shape of a cuboid and is dimensioned so that it can easily be gripped with one hand.
  • the cleaning body is delimited by a scouring surface 1, in the longitudinal direction by the two end surfaces 4, 5 and in the transverse direction by the two side surfaces 2, 3.
  • the longitudinal surfaces 4, 5 and the side surfaces 2, 3 extend essentially perpendicular to the abrasion surface 1.
  • the cover surface 6 preferably extends parallel to the abrasion surface 1.
  • the side faces 2, 3 delimiting the cuboid and the end faces 4, 5 on two diagonally opposite one another Ends are connected by a rounding 11.1 and each other Cut through the other ends in a sharp edge 9.
  • One of the sharp edges delimits the rear face at the left end.
  • the side faces 2, 3 and the end faces 4,5 form an angle of 75 ° with each other.
  • the cleaning body can be in the area of the edges 9 hold particularly tightly without causing local overuse of the flexible material that forms it or excessive dimensional changes or deformation of the Abrasion surface. An impairment of usability or unintended slipping is not easy to fear. Also with a view to avoiding Fatigue of the cleaning body, this is of great advantage to human hands.
  • the scouring surface 1 is with a scrub-active, liquid-permeable Coated with an elastomeric polyurethane.
  • Figures 2 to 5 show versions of the cleaning body in plan view, which differs from that described above are designed. Stretches in all versions the not visible scouring surface 1 parallel to the visible top surface 6.
  • the cleaning body can be analog 1 from any relevant foam or textile used.
  • the front end face 4 rounded in a semicircle. she runs tangentially in without a sudden change of direction the side surfaces 2,3.
  • the rear face closes the longitudinal direction of the longitudinal surfaces an acute angle of 75 ° on. It ends on the left in a sharp Edge 9 and is rounded off on the right 11.1 connected to the right side surface 3.
  • the rounding off has a radius of approximately 20 mm with a width of the cleaning body of about 75 mm.
  • the cleaning body thus has over several radii, sharp edges and abrasive surfaces a different shape and size. He lets himself therefore versatile in household and commercial use.
  • Fig. 3 differs from that described above in that the bounding the cuboid Sides and end faces 2, 3; 4, 5 at two each other diagonally opposite ends by rounding 11.1 are connected and sharp at each other at the other ends Limit edges 9.
  • the end faces 4, 5 close in this Version with the longitudinal direction of the side surfaces 2, 3 an acute angle, which is about 70 °.
  • FIG. 4 The embodiment shown in FIG. 4 is characterized by that the sides and end faces 2, 3; 4, 5 at two diagonally opposite ends an inclined surface 11 are connected and each other on the rest Limit ends in a sharp edge 9.
  • the end faces 4, 5 close with the longitudinal direction of the side surfaces 2, 3 a right angle.
  • the cuboid is on rear end delimiting end face 5 on the one hand by a Inclined surface 11 and on the other hand by a sharp edge 9 limited, the end face with the longitudinal direction of the Side surfaces 2, 3 connects an angle A of about 70 ° and the inclined surface has an obtuse angle B of 150 °.
  • the front one End face 4 closes with the longitudinal direction of the side faces 2, 3 a right angle.
  • the inclined surfaces 11 can be in the versions 4 and 5 particularly simply by a straight Cut and create waste-free. Nevertheless, it also succeeds in this case due to the elastic deformability of the Blocks of fillets forming fillets and fillets of household dishes, for example, is particularly simple to wipe.
