Definitions

  • the invention relates to a brush that can be held and guided by the user by hand, so a hand brush, and as used in particular when rinsing kitchen utensils such as pots, pans, bowls for the removal of adhering to such parts impurities.
  • Dishwashing brushes which have a bristle stocking of more or less rigid bristles, usually with a small bristle cross section of less than one square millimeter, which run parallel to one another or are also arranged in a V-shape relative to one another.
  • These conventional bristles are usually arranged in bristle bundles, within which the distance of the bristles, at least in the attachment region on the base body goes to zero, while the distance between the bristle bundles is usually of the order of a diameter of such a bristle bundle, or even about that.
  • a handle which serves as a handle for the user or the brush head is opposite to the bristles Part of the body of the brush, the back, held directly by the user
  • Dishwashing brushes of known design usually have only a single bristle area, which is primarily suitable for cleaning flat or slightly curved, in particular, convex curved surfaces by the bristle end surface in which lie the bristle ends of the bristle trim, either a flat or a weak represent convex curved bristle end surface.
  • the bristles in the known dishwashing brushes usually only one bristle area present over the entire bristle area uniform hardness, ie elasticity, of the bristles, so that this existing hardness of the bristles can not be optimal on the one hand for large-scale rapid removal of easily adhering deposits and on the other hand for the removal of very strongly adhering deposits, as is particularly strong curved, form concave surfaces.
  • this object is achieved in that the attached at the front end of the brush handle brush head not only one, but two bristle portions, each of which has a base surface, of which the bristles, at least in a bristle region primarily in the same direction, ie preferably essentially parallel to each other, protrude.
  • This base surface is either plane and thus defines a main extension plane, or it is curved, in which case the tangential plane such a curved base surface defines its main extension plane.
  • each of these two base surfaces extends at an acute stem angle to the direction of travel of the stem, the stem direction, and the two bristle regions are - viewed in the stem direction - arranged at different circumferential positions of the stem direction, preferably with respect to the stem exactly opposite each other.
  • stem is not straight, should be understood by the stem direction that direction in which the brush head adjacent front end, so the beginning of the stem protrudes from the brush head.
  • the two bristle regions can each be used alternately-merely by turning the handle about its stem direction-on the object to be cleaned, depending on the specific task at hand.
  • the other, second bristle region has a strongly convexly curved or even wound bristle-end surface whose minimum deflection from its bristle-end plane is at least 20% of the greatest extent of the base surface of this bristle region, better at least 40%, better at least 50%, better at least 60%, better at least 70% of the largest extent of this base area.
  • the first bristle area can be used very well for cleaning flat or slightly curved, in particular convexly curved, surfaces
  • the second bristle area can be used very well for cleaning strongly concavely curved surfaces, since it has a large area Contact surface between the bristles of this bristle portion and this surface to be cleaned causes.
  • the bending edge of this wound bristle end surface runs skewed to the stem direction, in particular the connecting line between the stem direction and the bending edge at the location of their smallest distance from each other in particular both the stem direction and / or the crease edge in is a right angle.
  • such a bristle portion with an angled bristle end surface can be used very well for cleaning inner edges, for example the inner edge between the bottom and the side wall of a pot or bowl.
  • the bristles in the different bristle regions may have a different hardness, but preferably equal within the bristle region.
  • the bristles in the bristle area with the highly convex post area are harder than those of the other bristle area.
  • the individual bristle regions can each be present in a separate bristle part fastened to a base body of the brush head, which comprises a bristle support body from which the bristles protrude.
  • the bristle parts should as quickly and easily, in particular without tools, be removed from the body of the brush head and mounted on this to quickly perform a replacement of a bristle part can.
  • the two main extension planes of the bristle areas occupy an acute intermediate angle with respect to one another, so that accessibility with the dishwashing brush is well possible both on lowered surfaces such as the bottom of a pot and on inner edges between the lowered surface and the side wall projecting therefrom.
  • the base surfaces of the two bristle regions preferably meet, in particular at their front end or even merge into one another, and thus are located in front of the front end of the brush stem or form this front end.
  • the base areas of the two bristle areas overlap in the longitudinal direction, the stem direction, by at least 30%, better 50%, better 70%, better 80% at least. As a result, both are approximately in the same length range and can be used in the same way by the user handling.
  • the stem angle of the first base surface is for optimum handling between 40 ° and 50 °, better between 35 ° and 45 °, better between 30 ° and 40 °, better between 25 ° and 35 °.
  • the stalk angle of the second base surface with the highly cranked or even angled bristle end surface is for the same reason preferably between 30 ° and 40 °, more preferably between 25 ° and 35 °, better between 20 ° and 30 °, better between 15 ° and 25 °.
  • the resulting by these angular positions intermediate angle between the two base surfaces is preferably between 70 ° and 80 °, more preferably between 60 ° and 70 °, better between 55 ° and 65 °, better between 50 ° and 60 °, better between 45 ° and 55 °, as this angle range has been found to be optimal for handling in the brush as a dishwashing brush.
  • the bristles protrude from their respective base surface in a direction of projection which always runs in the same direction away from the base surface, namely away from the base body, the direction of deflection relative to the base surface usually 90 °, in any case at least 60 °, better at least 70, better at least 80 °.
  • the handle has a non-round, in particular polygonal, preferably approximately triangular, cross section, whereby twisting in the user's hand is difficult and the brush can be better held.
  • the stem is preferably formed integrally with the main body, in particular as an injection molded part, but it may also be two separate parts which can be put together and in particular locked against each other, preferably in different rotational positions about the stem direction, with a rotation angle difference accordingly the number of corners of the polygon.
  • a non-straight, in particular slightly curved, handle can be mounted projecting in different rotational positions, depending on the current needs in the application.
  • the stem is straight.
  • the brush handle is tubular, that is hollow, formed in a large part of its course by having at least one of the rear free end, facing away from the brush head end, extending into the interior of the brush handle recess.
  • This recess can be used so that the brush has a scraper comprising a scraper shaft and a scraper head attached thereto, at least the scraper shaft, preferably also the scraper head, fitting into the hollow brush shaft.
  • the scraper head can be designed so that it can close in particular the free end of the brush handle as a plug, or also in the brush handle can be inserted, so then the other, facing away from the scraper head, end of the scraper handle has such a design that it is the Close opening of the brush handle as a plug and / or can lock against this.
  • the scraper head preferably has a straight or slightly curved scraper edge and / or scraper projections, in particular on the scraper edge, and / or also away from it.

  • the bristles should preferably have a relatively high flexural strength transverse to the skin extension direction of the bristles, preferably a hardness between 60 shore and 90 shore, more preferably between 65 shore and 80 shore.
  • bristles made of a rubber-like material, in particular of synthetic rubber or natural rubber are particularly well suited.
  • Such rubbery bristles may be integrally formed together with the bristle support body, for example by injection molding.
  • the bristle support body has a higher hardness than the bristles and is for example so dimensionally stable that it can be fixed by means of the aforementioned bayonet closure on the base body.
  • the bristle-supporting body may be formed so elastic, and in particular the same hardness as the bristles, that it is held on the base body by means of its inherent elasticity, by spanning the contact surface and surrounds the edge, so engages below,
  • the cross section of the bristles should have at least one, preferably 3 or more indentations distributed over the circumference, at least in the free end region of the bristles, the intermediate angle between the flanks of the indentation - regardless of whether its contour is rounded or angular - preferably greater than 40 ° should preferably be 50 ° , in particular even greater than 70 °, better still greater than 90 °, but preferably not greater than 100 °.
  • the bristles have a star-shaped cross-section in which a plurality of arms protrude from a center of the cross-section, and preferably the cross-section is X-shaped in that, from a center, four arms extend uniformly circumferentially from a center of the cross section.
  • the bristle ends have an end surface which is preferably parallel, preferably identical to the bristle end surface, that is not necessarily at right angles to the direction of extension of the bristles.
  • this object is achieved by at least one type of base body is present, and at least one type of first and second bristle carrier, as described above and optionally of each of these first and second design variants with different elasticity, ie hardness of the material of whose bristles, in particular the bristle carrier body, are present.
