Definitions

  • the present invention relates to a shaping tool for use in the treatment of a surface of body extremities of mammals, in particular the nails or the skin of humans.
  • a rotating shaping tool is used, which tool has an elongated shaft, one end of which shaft can be clamped and the other end of which shaft holds an operative section with a rotationally symmetrical operative zone, which operative section shapes the surface while abrasively removing parts of the surface and which projects beyond a diameter of the shaft.
  • shaping tools are used that are adapted to the morphology of the body extremity, i.e., the foot, and of the nails as well as of the occasionally occurring deformities.
  • This type of single-piece rotating shaping tool in particular one that can be cooled, is known, for example, from DE 229 008 683 U1.
  • the shaping tool described in this document is especially suitable for use in foot care.
  • the rotating shaping tool has an abrasive material bonded to it, and the remainder is made of metal.
  • the outer surface is shaped like a cap, and the abrasive material bonded to it is diamond grit.
  • the use of the shaping tool in particular when known cutting or abrasive tools are used carelessly, entails the risk of injury to the extremity due to the surface-effective, in particular abrasive, i.e., material removing and/or abrading zone of the shaping tool.
  • abrasive i.e., material removing and/or abrading zone of the shaping tool.
  • the problem to be solved by the present invention is to make available a shaping tool which greatly minimizes the risk involved when shaping extremities and surfaces thereof, in particular in foot care clinics and nail care salons.
  • a rotating shaping tool especially designed for this purpose which tool has an elongated shaft, one end of which shaft can be clamped and the other end of which shaft comprises an operative section with a rotationally symmetrical operative zone which shapes the surface while abrasively removing parts of the surface, which operative zone projects beyond a shaft diameter, with the operative zone, on the end opposite to the shaft end that is to be clamped, being bounded by a rounded part having a domelike structure without the surface-shaping function that is inherent in the operative zone.
  • the domelike region has a rounded-off part. This makes it possible to avoid the risk of injury which is inherent in the prior-art shaping tools especially due to the edged design. Since, in addition, it was found to be especially useful to dispense with a surface-shaping function that is inherent in the operative zone, i.e., to omit this region of the domelike structure completely, the shaping tool can be placed on the surface of the extremities without, however, itself abrasively shaping the surface. As already mentioned above, “abrasive” in the context of the proposed technical teaching of the present invention is meant to indicate that, because of the surface shaping function inherent in the operative zone, material can be removed from the surface.
  • the domelike structure is smooth, and if a metal is used, it is polished.
  • the shaping tool it is possible to first place it on the surface and subsequently cautiously approach the area on which a surface of the body extremity is to be actually shaped. Only by tilting the shaping tool and/or by moving the shaping tool down to a deeper level is it possible for the operative zone to come into contact with the surface and for abrasive removal of material from the surface to take place.
  • the domelike structure at least on the surface, can be made of a material different from that of the operative section.
  • the domelike structure can be coated with a coating.
  • the domelike structure can also be a separate element that contributes to the shape of the operative section.
  • the domelike structure can be attached, for example, by means of a joining method, an adhesive method or a similar method.
  • the domelike structure is a fusion-bonded component of the operative section. In this case, the domelike structure is preferably produced from a preliminary product if the operative section is made from the preliminary product.
  • the shaping tool is produced by means of a machining method, for example, a turning procedure
  • a turning tool used in this procedure can produce the domelike structure in such a manner that at the same time the surface in this area is smooth and thus, in particular, an additional polishing step can be dispensed with.
  • the shaping tool is produced, for example, by means of a high-quality casting method, the cast product can have such a surface quality that, again, a separate step of finishing the domelike structure can preferably be dispensed with.
  • the domelike structure can be coated with a coating.
  • the operative zone can also be coated with a coating.
  • the operative zone and the domelike structure are coated with a coating. These coatings, for example, differ from each other in that they are made of different materials and/or have different properties. According to one embodiment, only the operative section is coated with a coating. According to one embodiment, the operative zone is preferably coated with a coating made of a material or a combination of materials different from the coating or the material of the domelike structure.
  • the coating of the domelike structure, the operative zone and/or the operative section can have a certain property, for example, it may be electrically non-conducting, it may be electrically conducting, elastic, have a higher surface smoothness than another material of the operative section, or the like. Furthermore, the coating can have a higher hardness than a substrate material or the core material, in particular, of the operative section.
  • the coating is preferably temperature-resistant and able to withstand temperatures of at least 134° C. and more without damage to it.
  • the separate element which, in the form of a domelike structure, contributes to the shape of the operative section can also have this same material property.

  • the coating is present already on a preliminary product.
  • a preliminary product for use in the production of the operative section of the shaping tool already has a coating on the domelike structure, which coating prevents that, in the step of bonding a material-removing substance or another abrasive material to the operative zone, the abrasive material is not applied to the domelike structure.
  • a protective coating can be used to prevent that the abrasive material adheres to the region of the domelike structure.
  • the surface in tis region does not have the surface shaping function of the operative zone.
  • a protective coating that prevents a bonding of an abrasive material to it can be designed so as to be removable. This can be achieved, for example, with the use of chemical procedures.
  • a galvanic coating method can be used to apply the abrasive material.

In another embodiment, however, such can be present.
  • the domelike structure begins to take on a hemispherical shape, with the surface, when viewed along the circumference, having concavities, such as are similarly known, for example, from a citrus press.

  • a surface of the domelike structures transitions steplessly into a surface of the operative zone. Because of the stepless transition, the risk of injury during use of the shaping tool is prevented since there are no sharp edges, such as the ones present in other prior-art shaping tools. This also allows the shaping surface of the operative zone to steplessly transition into the domelike structure. In this manner, it is again possible to avoid a stepped edge which could carry the risk of injury when the shaping tool is used.
