Definitions

  • the invention relates to a rubber broom, comprising a broom body one arranged on its underside, integrally merging trained bristle assembly made of an elastic, polymeric material, the edge of the broom body protruding laterally Bristles is overlapped and the bristle ends in the ready-to-use condition of the Broom lying on one level. Furthermore, a method for producing a Rubber broom object of the invention.
  • Such a rubber broom is known from EP-B 0 405 819.
  • the broom body and the bristle assembly form a single molded part, that is produced in the injection molding process. It is in the head of the broom a reinforcement insert is embedded.
  • the headboard has a flat underside on which the bristles are attached.
  • the bristles are in the side area spread to the side.
  • the mold used for the production is like this designed that the edge of the broom body from in the lateral direction protruding bristles is overlapped. This makes it possible to Using such a rubber broom dust and dirt from the Range of corners between a floor surface and a floor surface to remove delimiting wall.
  • the manufacture of the required the molding tool is extremely difficult and the shaping of the generated injection molded parts problematic. Often, bristles tear off what makes a rubber broom unsaleable.
  • a rubber broom in which a bristle part around a holding body is guided around, the bristles being in the edge region removed from the ground.
  • the holding body is on its outer Ends pulled up.
  • the invention has for its object such a rubber broom to develop further that corners are easier and safer to manufacture have rooms cleaned just as easily as with the known one Execution.
  • the Broom body is a molded part produced independently of the bristle configuration and has an underside that runs all the way towards the edge Scope is pulled up
  • the bristle assembly is part of a deformable base layer and wherein the base layer is the underside touched at least along the circumferential edge.
  • the essentially Bristles protruding perpendicularly from the base layer are in the hoisted area shifted sideways outwards what it allowed, using the rubber broom according to the invention Corner areas between the floor and one perpendicular to it Clean the wall perfectly without touching the Broom body on the wall.
  • the bristles can be columnar, but if necessary also in protruding area of tapered cross-section.
  • profiles with circular cross-section are preferably rectangular Cross section for the application, which extend transversely to the cleaning direction.
  • An overlapping, mutual assignment of the bristles has proven to be advantageous proven.
  • the back one Area, i.e. the non-protruding bristles can have a round profile Cross section have good elasticity available in all directions to have. The achieved during the intended use This significantly improves the cleaning effect.
  • An integration wiping lips in the bristle assembly is also possible, preferably in an arrangement in which every other row within the bristle assembly is formed by at least one wiper lip.
  • a wiper lip can be used also several successive or laterally in the direction of movement spaced partial lips include those of limited length and on each other Gap are assigned. This increases the flexibility of the wiper lip improved overall. Regarding wiping off dirt and / or Water from uneven surfaces and especially from recesses can be one achieve improved squeegee effect.
  • the rubber broom is symmetrical is designed such that the bottom at both ends in the direction of Edge is pulled up.
  • Such a rubber broom can be used equally well in with regard to the cleaning of right and left corners, without this Turning the broom body required.
  • the bottom can also go all the way towards the edge be pulled up in all directions over the edge area to have the above bristles available.
  • the underside of the broom body can be opened in the central area independently generated intermediate plate formed in an opening of the Broom body is insertable and the broom body and the base layer connects with each other.
  • the additional manufacture of the intermediate plate is true involves a lot of effort, but the effort is far outweighed made by the resulting material and weight savings.
  • the intermediate plate opens up the possibility of the base layer almost to bring it into any shape convexly projecting downwards and fix immovably on the broom body without it being insert needs a secondary adhesive.
  • the base layer can be on the top with projections of T-shaped extending parallel to their longitudinal direction Profile be provided, the projections in their cross section Appropriate, open downward recordings of the intermediate plate inserted are.
  • Such a support of the base layer also has a certain degree In terms of resilient properties, it is largely excludes that during the intended use unintentional detachment of the base layer from the broom body results. Also with such training it is not necessary for the production of the Brush body and the base layer or the bristles related materials to use to make a sufficiently stable fixation to each other enable. Both for the manufacture of the broom body, as well as for the The intermediate plate and the base layer can therefore use materials be, which in a specific way to the special requirements of the relevant item are adjusted. It has proven to be advantageous for to use the manufacture of the polypropylene broom body for which Production of the intermediate plate polyamide and for the production of the Base layer including the bristles a thermoplastically processable Rubber grade (TPE).
  • TPE thermoplastically processable Rubber grade
  • the intermediate plate can have at least two holding tabs projecting upwards have, with corresponding, the broom body in the transverse direction penetrating openings can be covered and together with these are penetrated by retaining bolts.
  • the base layer can be delimited in the circumferential direction by a bead which encloses the lower edge of the broom body on the outside. This will not only prevents that when touching walls or Furniture is damaged but additionally penetrates Dirt in the space between the base course and the Broom body prevented. From a hygienic point of view, this is from great advantage.
  • Another object of the invention is a method for producing a prescribed rubber broom, the rubber broom being a broom body with one arranged on the underside, in one piece bristle configuration made from an elastic, comprises polymeric material, the edge of the broom body from in bristles protruding laterally, the bristle ends of ir ready-to-use condition of the broom lie in one plane and the Broom body is a molded part produced independently of the bristle configuration with an underside drawn up at both ends in the direction of the edge is and wherein the bristle assembly is part of a deformable Base layer which forms the at least along the circumferential edge Touched the underside of the broom body.
  • the broom body is produced in a first step Another step is to make the base course substantially perpendicular to it arranged bristles in a substantially flat shape and in a further step the base layer is applied to the broom body stretched, which is essentially perpendicular from the base layer protruding bristles in the raised all around Area to be moved sideways outwards.
  • the rubber broom shown in Figures 1 and 2 comprises a Broom body 1 with one piece arranged on its underside bristle assembly 2 formed from one another elastic, polymeric material, for example made of TPE.
  • the broom body 1 consists of an injection molded part made of polypropylene, which is hollow and is formed independently of the bristle configuration 2.
  • the broom body 1 has an underside, which in the direction of the two front ends in Area 3 at an angle of 30 °, based on the imaginary Extension of the central area, pulled up, the Transition zone between the raised area and the central one Area rounded is merged into one another.
  • the bristle assembly 2 forms part of a deformable Base layer 4, which is produced in a flat shape and during its attachment the underside of the broom body 1 is deformed so that a continuous contact on the underside of the broom body 1 results at least along the circumferential edge.
  • the in the field of Bristles of the bristle assembly 2 located at the front ends thereby transferred to a position which is the front end of the broom body 1 overlap by dimension A. This allows the rubber broom to be used excellent for cleaning the corner between a flat floor surface and use walls perpendicular to it.
  • the rubber broom shown in Figure 1 is designed so that the Bristle 2 base layer 4 only in the area of each other opposite, end ends is pulled up, whereby only in bristles of the bristle assembly projecting laterally from these two areas 2 are available.
  • the invention is not limited to this training but also includes versions in which the broom body 1 in all Directions of bristles of the Bristle assembly 2 is enclosed. Such an embodiment is shown in FIG reproduced cross-sectional representation.
  • the Base layer 4 having bristles 2 is on an intermediate plate 5 stretched across the entire circumference towards the edge of the Broom body 1 is pulled up and is convex in the central region.
  • the bristles of the bristle assembly 2 are not only analogous to FIG.
  • the intermediate plate 5 is converted into the shape shown.
  • the base layer 4 is positively attached to the intermediate plate 5.
