Definitions

  • the invention relates to a manual cleaning device, comprising a cleaning member delimited at least over a portion of its periphery by an edge which is formed in a plane and which is dome-shaped on one side of this plane.
  • a manual cleaning device with the aforementioned features is disclosed in DE-A-199 41 718.
  • the known cleaning member is essentially a truncated cone having a small top surface which is semi-spherical and having a base surface that has a greatly rounded edge.
  • a coupling member for a handle adjoins this edge/rounded portion.
  • This coupling member is rotationally symmetrical and concave.
  • the known manual cleaning device is rather large in the area of the cleaning member. For narrow areas and for undercuts, as they are known, in particular, in toilet bowls, the known manual cleaning device is therefore not optimal.
  • the manual cleaning device should also be particularly easy to handle in order to use it also, for example, as a cleaning device for the body.
  • This object is solved in that the cleaning member is formed on both sides of the edge with a flat domed configuration and that the periphery of the cleaning member, having a flat domed configuration on both sides, has an oval shape at least in the area of its edge.
  • the cleaning member is of a flat domed configuration on both sides of the plane defined by its edge.
  • the cleaning member has two differently sized cross-sections with respect to planes that are perpendicular to one another.
  • the dimensions in that plane that is determined by the edge of the cleaning member can be made large in accordance with the cleaning tasks, for example, with respect to the large cross-section of a siphon trap of a toilet bowl or with respect to large surfaces of the body to be cleaned when the cleaning member is to be used essentially as a massage brush or bath brush.
  • the oval edge corresponds excellently to the containers employed usually in the sanitary field which also a have oval cross-sections or radii and therefore can be cleaned in a simple and reliable way.
  • Perpendicularly to the plane which is defined by the edge the cross-section is small as a result of the flat-domed configuration of the cleaning member.
  • a handle is connected to the cleaning member and that the cleaning member has a cleaning projection projecting asymmetrically, relative to the handle, in the plane defined by the edge.
  • a cleaning tongue results with which undercuts can be cleaned.
  • the flat-domed configuration contributes to the fact that flat curved surfaces can be cleaned very well because the flat domed configuration of the cleaning member corresponds approximately to the flat concave configuration of, for example, a toilet bowl and, in this way, a cleaning action for large surface areas is enabled.
  • the manual cleaning device can be configured such that the cleaning projection of the cleaning member is positioned at an acute angle relative to the handle.
  • the cleaning projection is therefore hook-shaped so that undercuts can be cleaned well which have practically vertically arranged surfaces.
  • the ease of manipulation of the manual cleaning device is therefore significantly improved even for cleaning areas that are otherwise considered to be problematic.
  • the handle is mounted on the cleaning member so as to be practically aligned with the plane defined by the edge.
  • the cleaning member which is of a flat domed configuration on both sides of such a body cleaning device is an excellent massage brush and bath brush member.
  • the flat domed shape of the cleaning member is excellently adapted in order to massage or brush the human body.
  • a further significant embodiment of the manual cleaning device is to be seen in that the cleaning member is of a flat drop-shaped configuration and in that the drop point forms the cleaning projection.
  • the drop shape of the manual cleaning member means that the cleaning member is pointed like a drop.
  • the drop point on the one hand, is so narrow that it can penetrate into areas of a very small volume in order to clean them.
  • it is of such a large size that the cleaning member retains the required stiffness.
  • a large radius is provided, and with this side areas of the toilet bowl can be cleaned, for example, which have concavely curved surfaces to be cleaned with correspondingly large or greater radii.
  • the drop-shaped configuration of the cleaning member effects accordingly excellent cleaning possibilities for surfaces to be cleaned which have large radii as well as for surfaces to be cleaned which have small radii or are located in undercut areas that are difficult to access.
  • the cleaning device can be designed preferably such that the edge extends continuously circumferentially and that it has a cleaning member that in the area of the plane defined by the edge is completely oval.
  • the complete oval configuration of the cleaning member has the result that the latter can be employed more easily. It is not required to rotate it for using its edge, this being the case when the edge is present only over a portion of the circumference of the cleaning member.
  • the cleaning member is thus particularly easy to handle.
  • a further advantageous configuration of the manual cleaning device is to be seen in that the edge is formed by pointed converging curved surfaces of the cleaning member.
  • the pointed converging curved surfaces of the cleaning member cause a correspondingly sharp edge. With this edge it is possible to scrape off even encrusted materials from surfaces to be cleaned.
  • the manual cleaning device can be embodied such that the cleaning member has a coupling member for the handle that is bead-shaped or bottleneck-shaped and extends in the direction toward the handle.
  • the bottleneck shape of the coupling member is slim and therefore does not impair the use of the cleaning member in narrow objects to be cleaned.
  • the manual cleaning device such that the coupling member at least in the vicinity of the circumferential edge of the cleaning member is dome-shaped and/or that the cleaning member and the coupling member are of a unitary configuration.
  • the area of the domed configuration of the coupling member can be used for cleaning tasks, for example, on surfaces to be cleaned which are substantially positioned parallel to the handle.
  • both members can be comprised of the same material and can be produced together in a single manufacturing step.
  • the stability of the manual cleaning device is enhanced when it is configured such that the coupling member encloses, with the exception of the coupling end for the handle, an adapter bolt projecting into the cleaning member or has a recess in which the handle is directly fastened.
  • the enclosed adapter bolt is completely protected with regard to soiling, in particular, when it is assumed that the coupling end is usually completely enclosed by the handle.
  • a less expensive configuration results by providing the coupling member with a recess in which the handle is directly fastened.
  • the handle can be pressed into the recess, glued therein, or can be embedded in the material of the coupling member by injection molding. This is particularly advantageous when the coupling member is produced of integral skin foam.
  • the cleaning member and/or the coupling member is comprised of dirt-repellent polyurethane foam with a self-lubricating surface and/or that the cleaning member and/or the coupling member is provided with a dirt-repellent coating.
  • the cleaning device therefore will not soil easily. Dirt does not find any surfaces to adhere to and water or liquid will drain off.
  • a dirt-protecting coating can have a Teflon-like anti-adhesion action, in particular, for grease. It can be baked in at a suitable temperature in order to provide a permanent activity.
  • An advantageous configuration of the manual cleaning device is characterized in that the curved surfaces of the cleaning member and/or a domed surface of the coupling member are provided with parallel uninterrupted flat pointed ribs.
  • the cleaning effect is enhanced when the cleaning member is moved under pressure on the surfaces to be cleaned. The pointed ribs then scrape off the dirt.
  • the manual cleaning device can be configured such that the pointed ribs on the coupling member extend past the domed surface to its end at the handle.
  • surfaces of the coupling member which are not dome-shaped can also be used for cleaning purposes; this can facilitate, for example, cleaning of surfaces to be cleaned which are not domed.
  • the manual cleaning device is configured such that the flat pointed ribs are profiled according to a circular section and/or alternate with flat ribs. Circular section surfaces all have the same minimal curvature which is optimized in regard to minimal soiling. On the tips of the flat pointed ribs, water and dirt can adhere only minimally. When the pointed ribs and flat ribs alternate, in the area of the pointed ribs an excellent scraping effect will result while the flat ribs enable a strong surface pressure which can be used in the sense of an effective removal of dirt particles.
  • a further optimization in the sense of minimal soiling of the manual cleaning device results when the pointed ribs of the cleaning member end at a spacing from its circumferential edge. Automatic dirt and water drainage in the area of the circumferential edge is thus improved.
  • the manual cleaning device can be characterized in that the pointed ribs extend at a slant to a longitudinal axis of the cleaning member.
  • the pointed ribs extend at a slant to a longitudinal axis of the cleaning member.
  • the manual cleaning device can be configured such that the rib edges of the pointed ribs are wave-shaped and that neighboring wave-shaped rib edges are arranged in the longitudinal direction with phase displacement.
  • the valleys and peaks of the waves are arranged alternatingly adjacent to one another, in the longitudinal direction of the ribs as well as transversely thereto; the latter realized as a result of the phase displacement of a rib edge to a neighboring rib edge.
  • the manual cleaning device In order for the manual cleaning device to be reliably gripped directly on the cleaning member in order to be able to perform, without using a handle, cleaning or massage tasks, the manual cleaning device is advantageously configured such that one domed curved surface is provided with pointed ribs and the other domed curved surface in the vicinity of the edge is provided with gripping knobs.
  • the gripping knobs effect that the gripped manual cleaning member will slip less likely our of the hand. They also represents a design element.
  • the cleaning member is provided with an adjustable timer and/or with a thermometer.
  • the cleaning member can be used without handle for massage and bath purposes but can be used also in connection with a handle.
  • the manual cleaning device can be configured such that the cleaning member has on at least one curved surface and/or on one dome-shaped surface area projections of a small surface area which are distributed across this surface or surfaces uniformly and/or in rows and have an outer contour with sharp edges. Depending on the configuration of the small surface area projections, this particularly provides a possibility for designing the cleaning device in a visually especially pleasing way.
  • the manual cleaning device such that on the end of the handle facing away from the cleaning member a grip with a structure is provided which corresponds to that of a curved surface of the cleaning member.
  • a grip with a structure which corresponds to that of a curved surface of the cleaning member.
  • the applicability of the manual cleaning device is improved in particular in that it is stored by being supported via the cleaning member in a support vessel.
  • the manual cleaning device therefore has a predetermined place from which it can be gripped.
  • the manual cleaning device can be configured with a handle or without a handle.
  • the support vessel can support the cleaning member such that the end of the handle is freely accessible and gripping of the manual cleaning device is facilitated in this way.
  • the manual cleaning device such that the support vessel is provided with a support rim which is arranged at a slant relative to a vertical line at an angle which corresponds to the acute angle between the handle and the cleaning projection of the cleaning member.
  • the manual cleaning device can be arranged with a vertical handle. It can therefore be reached without having to bend over too much, even when the support vessel is of a flat configuration.
  • the unit comprised of the manual cleaning device and of its support vessel can be configured to be space-saving in the horizontal direction.
  • a configuration of the manual cleaning device is characterized in that the support vessel has a cylindrical outer wall and in that an inner wall tapering from an upper edge of the outer wall to the support rim provided within the outer wall is at least partially provided.
  • the tapering inner wall facilitates an exact placement of the manual cleaning device with its handle because the cleaning member by means of the tapering inner wall is guided to its seat on the support rim. Placing the cleaning member by means of a handle is thus facilitated.
  • the manual cleaning device can be configured such that the support rim is a continuous support surface in the peripheral direction which is interrupted by at least one recess allowing bottom ventilation of the cleaning member.
  • the continuous contact surface of the support rim provides a safe supporting action of the cleaning member.
  • the support vessel has a drip pan which tightly adjoins the inner circumference of the support rim and/or such that the drip pan and/or the inner wall in the area of the recess is recessed without a penetration.
  • the manual cleaning device can be configured such that the support vessel is manufactured of plastic material or glass or metal so as to have the same wall thickness throughout.
  • a particularly safe support of the cleaning member on the support vessel results when the support rim is slanted and/or formed so as to match the portions of the lower curved surface adjoining the edge. This provides a corresponding positive-locking and/or frictional connection.
  • the slanted surfaces of the support rim enable a complete areal support of portions of the lower curved surface of the cleaning member.

  • the upper edge 53 is connected with the support rim 51 by means of an inner wall 54 which guides the cleaning member 12 , 120 upon insertion into the support vessel 50 toward the support from 51 .
  • the tapering of the inner wall 54 facilitates thus the insertion of the cleaning member 12 , 120 .
  • the inner wall 54 must not be configured continuously about the entire circumference of the support rim 51 .
  • This advantageous configuration can be achieved in particular in that the support vessel is manufactured with a uniform identical wall thickness. Manufacture is realized, for example, by injection molding of plastic material, by pressing glass, or by deep-drawing metal. In this way, preferably a downwardly closed configuration of the support vessel 50 results.
  • a drip pan 56 adjoins the inner circumference of the support rim 51 and receives the draining or dripping liquid so that soiling of the floor is prevented.
  • the downwardly closed configuration of the support vessel 50 also contributes to simplified cleaning.
  • the support vessel 50 has two oppositely positioned recesses 55 which vent the bottom of the cleaning member 12 , 120 resting on the rim.
  • the recesses 55 are boat-shaped and extend transversely to the support rim 51 from the area of the inner wall 54 to the area of the drip pan 56 and are themselves provided free of penetrations. Venting of the bottom of the cleaning member 12 , 120 resting on the rim results in a reduction of enclosed air and possibly occurring rotting processes of soil particles.
