Definitions

  • the invention relates to a nail cleaning brush with a handle element that receives a bed of bristles, the bed of bristles having a bed section on which a plurality of bristles are arranged protruding, which form a bristle field.
  • Nail brushes are known in various forms. Nail brushes usually have a handle element, for example made of wood.
  • the handle body has bores in which bristles or bristle bundles are drawn in and fastened therein.
  • This object of the invention is achieved in that the bed section, together with the molded-on bristles, forms a molded body made of silicone material, in particular of silicone elastomer.
  • the one-piece design of the end section with the molded-on bristles can significantly simplify the parts and assembly effort.
  • the nail cleaning brush can be easily cared for. In particular, it can be easily cleaned under running water.
  • the transitions between the bed section and the bristles can be easily cleaned.
  • the nail cleaning brush according to the invention also has a good cleaning effect.
  • a user can place his fingers on the bristles of the bristle bed and move them back and forth in periodic movements.
  • the bristles grip under the fingernails and are pulled along under the fingernails.
  • the silicone material used in particular the silicone elastomer, has a particularly high cleaning effect. Due to its elastic properties, the silicone elastomer creates a high restoring force that becomes effective when the bristles are bent. At the same time, the bristles deform and fit precisely under the nail without this being perceived as uncomfortable.
  • the bristles are molded onto the bed section by means of a fastening section, that a transition section adjoins the fastening section, or that the fastening section forms the transition section, that the transition section moves the bristles towards the free
  • the end of the bristle tapers, and that the bristle has an end section, preferably in the form of a convexly curved cap section, at its free end.
  • the nail cleaning brush can be easily cleaned without creating places where dirt residues are permanently deposited.
  • the tapered geometry of the bristles reduces the bristle cross-section and thus the restoring force that is made available due to the elastic properties of the silicone material. This has the effect that the bristles fit the finger contour as precisely as possible snuggle under the nail. If a convexly curved cap section is used at the end of the bristles, the nail cleaning process is perceived as particularly pleasant.
  • a preferred variant of the invention is such that the cross-sectional area of the fastening section in the connection area to the transition section is smaller than the cross-sectional area of the transition section in this area or is equal to the cross-sectional area of the transition section in this area.
  • a further preferred variant of the invention can be such that the transition section continuously tapers the cross section of the bristles in the direction of the free bristle end, and that the outer contour of the transition section is convexly curved. It has been shown that the convex contour of the transition section leads to a particularly good cleaning effect below the nail. In particular, this also continuously reduces the cross section of the bristle and thus also the moment of resistance against bending. In this case, a sufficiently high flexural strength can still be achieved via the convex design, particularly in the area of the end of the bristles.
  • a conceivable embodiment of the invention can be such that the transition section has two section areas merging into one another, both of which have convex outer contours and that the curvature radii of these outer contours differ from one another. This allows the moment of resistance against bending to be influenced in a more targeted manner.
  • the ratio of the dimension of the longitudinal extent of the bristle in the longitudinal direction of the bristles to the maximum cross-sectional dimension, in particular the maximum diameter of the bristle is in the range between 2.5 and 5.5. With such a dimensioning, both short and long nails can be cleaned easily. This ratio is preferably selected in the range between 3 and 5. The inventors have recognized that a ratio of 4 offers a compromise for a variety of nail shapes. Additionally or alternatively, it can also be provided that the dimension of the longitudinal extension of the bristle in the longitudinal direction of the bristles is less than 15 mm. In particular, it is less than 10 mm, particularly preferably 6 mm, and / or that the maximum cross-sectional dimension, in particular the maximum diameter of the bristle is selected in the range between 1 and 3 mm, particularly preferably 1.5 mm.
  • the handle element is designed like a housing and has a base from which two opposite side walls and two opposite end walls rise, the side walls and the end walls surrounding a receiving area, and that at least one of the side walls has a Has a recessed grip, then the nail cleaning brush is compact and easy to use.
  • the side walls and the end walls can also be designed in such a way that they form a circumferential wall.
  • a nail cleaning brush according to the invention can also be characterized in that the bristle bed is supported with the side of the bed section opposite the bristles on a support of a carrier, and that the carrier is preferably detachably connected to the grip element.
  • Such a nail cleaning brush is material-optimized, because the bristle bed can be made relatively thin, with it being stably supported by the support of the carrier.
  • an edging area is formed on the bed section, preferably circumferentially, which is led around the edge of the support at least in some areas directly or indirectly following the support surface of the support.
  • the bed section can easily be connected to the carrier, in particular also in such a way that no additional fastening element is necessary.
  • the bed section is additionally connected to the carrier, for example glued.
  • the border area is at least one molded on Has undercut element which engages behind the carrier on its underside facing away from the support surface.
  • the bristle bed Due to the elastic properties of the bristle bed, it can be pulled around the edge of the carrier, the undercut element being used for a secure, form-fitting fixing. In particular, the assembly can be made simple as a result. It is also conceivable that the connection between the carrier and the bristle bed is detachable. A user can thus easily dismantle the bristle bed and clean it separately from the carrier.
  • the bristle bed can be prevented in a simple manner from inadvertently detaching from the carrier.
  • the border area lies against the inner sides of the side walls and the end walls in a sealing manner.
  • the bristle bed with its elastic properties then simultaneously forms a sealing element which prevents water from penetrating into the housing space formed by the grip element.
  • an opening area is formed in the area of the enclosure area, which creates a spatial connection between the surroundings and the housing area surrounded by the grip element. If water unintentionally penetrates the housing space, it can flow away again via the connection area.
  • a simple connection between the bristle bed and the grip element can be created in that the carrier carrying the bristle bed has plug-in attachments formed on its underside facing away from the bed section of the bristle bed, and that the plug-in attachments are inserted into plug-in receptacles of holding attachments of the grip element and preferably therein are held positively.
  • the bristle field has a central area, to which end areas adjoin on both sides, that in the central area the Bristles are arranged linearly in the direction of the longitudinal extension of the nail cleaning brush, these straight bristle lines running between the two end regions, and that in the end regions the bristles are assigned to one another in such a way that arc lines are produced which preferably run concentrically to one another.
  • an excellent cleaning effect can be achieved.
  • the nails can be guided linearly over the lines in the center area and are cleaned in the process.
  • the bristle constellation changes and the bristle exposure to the nails changes, so that effective nail cleaning is possible at different nail locations.
  • Figure 1 shows a nail cleaning brush with a handle element 10 which carries a bed 30 of bristles.
  • the grip element 10 is designed like a housing. In particular, it can be manufactured as an injection-molded part from one piece.
  • the grip element 10 has a base 11. Two opposing side walls 12 and two opposing end walls 13 adjoin the base 11 in one piece.
  • the side walls 12 and the end walls 13 rise from the floor 11.
  • the side walls 12 and the end walls 13 merge into one another, so that a circumferential wall is formed.
  • the side walls 12 form recessed grips 14 on their outer sides. These are recessed into the side walls 12 for easy handling of the nail cleaning brush.
  • Retaining lugs 16 are integrally formed on the bottom 11 of the grip element 10.
  • the retaining lugs 16 can in particular be designed in the manner of a dome and have plug-in receptacles which can be designed in the form of bores.
  • stiffening ribs 15 are provided.
  • the stiffening ribs 15 are integrally connected to the base 11 and the side walls 12 or the end walls 13.
  • the circumferential wall formed by the side walls 12 and the end walls 13 forms an upwardly open opening of the grip element 10.
  • a carrier 20 can be connected to the grip element 10. How Figure 6 further shows, the carrier 20 has a receptacle 21 which is plate-shaped.
  • the support 21 forms an upper support surface 23, which can in particular be of planar design. Opposite the support surface 23, the support 21 forms an underside 24. Plug-in lugs 22 are integrally formed on the underside 24.
  • the carrier 20 is manufactured as an injection-molded part made of plastic.
  • a bed of bristles 30 can be connected to the carrier 20.
  • the bristle bed 30 has a bed section 31. On the edge side, the bristle bed 30 has a circumferential border area 31.1.
  • the design of the bristle bed 30 can be closer to the Figure 7 remove.
  • the bed section 31 is formed by a sheet-like element.
  • the border area 31.1 adjoins the end section 31 in the form of a preferably circumferential web section protruding towards the underside.
  • At least one undercut element 31.2 is integrally formed on the free end of the border area 31.1.
  • the undercut element 31.2 is preferably formed circumferentially.
  • the bristle bed 30 has a multiplicity of bristles 34. These bristles 34 are arranged on the upper side of the bed section 31 and are connected in one piece to the bristle bed 31.
  • the bristle bed with the integrally molded bristles 34 consists of a silicone elastomer.
  • the bristle bed 30 To connect the bristle bed 30 to the carrier 20, the latter is placed over the carrier 20 in such a way that the border area 31.1 encompasses the circumferential edge of the support 21.
  • the carrier 20 can be connected to the grip element 10 with the mounted bristle bed 30.
  • the carrier 20 is inserted into the open side of the handle element 10.
  • the plug-in lugs 22 engage in the plug-in receptacles of the holding lugs 16.
  • the dimensions of the plug-in attachments 22 are preferably designed so that they can be inserted into the plug-in receptacles with a press fit. This results in a force-fit connection between the carrier 20 and the grip element 10.
  • the bristle bed 30 When the carrier 20 is mounted, the bristle bed 30 rests on the outside with its border area 31.1 on the facing inner sides of the side walls 12 and the end walls 13.
  • the material of the bristle bed 30, which consists of silicone elastomer, is elastically deformed at the border areas 31.1. This results in a circumferential sealing seal between the bristle bed 30 and the grip element 10. This seal prevents water from penetrating into the housing area.
  • the bristle bed 30 is prevented from being unintentionally pulled off the carrier 20.
  • the bottom 11 of the grip element 10 has a convex contour. This hugs the palm of the hand so that the grip element 10 can be held comfortably and securely. Handling is also improved by the recessed grips 14.
  • Figure 3 shows that the bristle field 32 of the bristle bed 30 is equipped with the bristles 34 in a special way.
  • the bristle field 32 has a central area 33. End areas 35 adjoin the middle area 33 on both sides.
  • the bristles 34 are arranged in such a way that straight bristle lines L1 to Lx are formed, the bristle lines L1 to Lx running in the direction of the longitudinal extension of the nail cleaning brush.
  • the bristles 34 are arranged in such a way that the bristles 34 form curved paths B1 to Bx. It can be provided in particular that the curved paths B1 to Bx of a respective end region 35 run on concentric circles. At least some of the curved webs B1 to Bx merge at their ends into the bristle lines L1 to Lx of the central region 33.
  • FIG Figure 5 shows the design of the bristles 34 in detail. Not all of the bristles 34 have to be designed as shown in FIG Figure 5 is shown. Advantageously, however, all of the bristles 34 are the same.
  • the bristles 34 are integrally formed on the end section 31 by means of a fastening section 34.1.
  • the bristle bed 30 can thus be manufactured in one piece from silicone elastomer.
  • the fastening section 34.1 can, for example, have a cylindrical shape.
  • a transition section 34.2 adjoins the fastening section 34.1.
  • the cross section of the bristles 34 is reduced in the direction of the free bristle end.
  • the bristles 34 are designed to be rotationally symmetrical.
  • the transition section 34.2 can have one or more sections. In the present embodiment, two section areas 34.3, 34.4 are provided, the section areas 34.3 and 34.4 continuously merge into one another.
  • transition section 34.2 is convex, like this Figure 5 clearly shows, two section areas 34.3 and 34.4 (or several support areas) are used.
  • the curvatures of the support areas 34.3 and 34.4 can be different, such as Figure 5 shows. However, it is also conceivable to use only one uniform transition section 34.2.
  • convexly curved end sections 34.5 are provided, which can be designed, for example, in the form of end caps.
  • the bristles 34 have a bristle length X extending in the longitudinal direction of the bristles.
  • the bristles 34 also have a maximum cross-sectional extension R.
  • other bristle lengths X or maximum Cross-sectional extension R can be provided. This is specified in more detail in the claims and is also described above.
