Definitions

  • the invention relates to a razor or thinning knife consisting of an elongated handle part, at the front end of which a razor blade is arranged and which on the opposite side to the cutting edge of the razor blade in the rear area has a protruding handle extension formed integrally with the handle part.
  • Razors or thinning knives are known and are used in particular by hairdressers and barbers.
  • the known razors each consist of an elongated handle part, at the front end of which a razor blade is arranged, which can be replaced by a new one after use.
  • a U-shaped cover rail is pivotally mounted in the rear area of the handle part at a distance from the rear end. When the razor is folded, the cutting edge of the razor blade comes to lie within this cover rail. For use, the cover rail is then folded upwards by more than 180 °, so that it forms a protruding handle attachment, with respect to which the operator holds the handle part of the razor on both sides with his fingers.
  • the cover rail is technically complex and thus the razor is expensive overall.
  • the protruding handle in the form of the cover rail cannot be designed ergonomically optimally, since the razor has to be folded up again.
  • the angular position of the cover rail can change slightly in the opened state, which proves to be particularly annoying during the shaving process.
  • a disposable razor of the generic type in which a razor blade is interchangeably arranged at the front end of an elongated handle part.
  • the rear end of the handle part is formed by a so-called fin, which defines a handle attachment. This fin extends to the rear end of the handle part and has an opening through which the user sticks one of his fingers in order to be able to pivot the razor, for example.
  • a disadvantage of this known disposable razor is the handle attachment in the form of a fin with an opening.
  • the user has the option, for example, of inserting the middle finger or the ring finger into the fin opening for the shaving process, there is the problem for the user where he should "accommodate" the remaining fingers, ie the ring finger and the little finger or only that little finger. These remaining fingers come to rest outside the fin, which results in an ergonomically unfavorable position since the contact between the fingers is lost.
  • this has a negative effect on the guiding properties of the razor.
  • the fin requires a lot of plastic material, which is disadvantageous for ecological reasons, particularly in the case of single-use products.
  • Another disadvantage is that the razor blade is replaceable, i.e. that when the razor blade becomes dull, it has to be replaced in a cumbersome manner and with dangers, which overall makes handling more difficult.
  • the cutting edge of the razor blade is freely accessible when not in use and thus forms a source of danger.
  • DE-C 191 999 discloses a razor, the handle of which is designed as an eye.
  • a cover cap can be pivoted at the rear end of the blade carrier stored, this cap has the eye in the pivot bearing. When the razor is brought into the operating position, this is pivoted upwards together with the cover cap.
  • the object of the invention is to improve the known razor or thinning knife with regard to its ergonomic properties, with regard to its handling and with regard to its safety.
  • a razor or thinning knife designed according to this technical teaching is characterized by its good ergonomic properties.
  • the short stub attachment fixedly arranged on the handle part can be designed in such a way that the user can hold the handle part of the razor or thinning knife in an ergonomically favorable manner.
  • "Short” is essentially to be understood as an order of magnitude in the length of the stub end which corresponds to the thickness of the fingers, so that they can rest comfortably on the side of this stub end.
  • the length of the stub end can be two to three times the thickness of the fingers.
  • the short stub extension is arranged at a distance from the rear end of the handle part and there can be space for several fingers, for example two or three fingers, in the recess formed therein, the guidance of the razor or thinning knife is improved during shaving, since the Fingers close to each other with respect to the stub end, which has an ergonomically positive effect on the guiding properties of the razor during shaving.
  • the recess formed in the grip part has the advantage that the fingers of the user lying in the recess cannot slip.
  • the razor according to the invention is very easy to use, since it is a so-called disposable razor, which is thrown away when the razor blade is used up.
  • this one-way use satisfies regulations that hairdressers and barbers have to use a new razor blade for each customer in order to meet the hygienic requirements.
  • the fact that the razor blade is permanently embedded in the handle part eliminates the problem of exchanging the razor blades.
  • the cover cap has the advantage that people cannot injure it when the razor is not in use.
  • the U-shaped clamping part can either pushed onto the handle in the longitudinal direction from the front or pushed perpendicular to the cutting edge of the razor blade. Due to the pretensioning of the U-shaped cover cap, it comes into contact with its mutually opposite inner walls on the sides of the handle part, so that the cover cap is fixed with respect to the handle part.
  • this has an opening.
  • this opening can also serve as a hanger for the razor.
  • the handle part has a double-T profile.
  • Such a cross-sectional profile in the form of a horizontal "H" has proven to be very favorable for high stability.
  • the razor or thinning knife consists of an elongated handle part 1 with a double-T-shaped cross-sectional profile, as can be seen in the sectional view according to FIG. 3.
  • the handle part 1 is a molded plastic part, in which a razor blade 2 is embedded in a non-detachable manner at the front end of the handle part 1, so that the razor blade 2 is completely covered laterally by the plastic material except for its cutting edge 3.
  • the handle part 1 consists of two individual plastic molded parts 1 ', 1 ⁇ , which are interconnected with the razor blade 2 interposed, the two plastic molded parts 1 being used for this purpose in the illustrated embodiment ', 1 ⁇ are provided with pins and corresponding recesses.
  • a one-piece plastic molded part can also be provided, in which the razor blade 2 is embedded during the injection molding process.
  • a cover cap 4 is fitted onto the front end of the handle part 1 to cover the cutting edge 3 of the razor blade 2, which in the exemplary embodiment shown is a snap-in clamping part with a U-shaped cross-sectional profile, as in FIG. 2 and in FIG. 6 and 7 can be seen.
  • a sack-shaped plastic film can also be provided as the cover cap 4, which can be plugged on in the longitudinal direction of the handle part and envelops this front end of the handle part 1.
  • a short stub lug 5 is formed, on the side of the handle part 1 opposite the cutting edge 3 of the razor blade 2.
  • the stub neck 5 has an opening 6 which serves on the one hand to save material and on the other hand to hang the razor. Furthermore, it can be seen in FIGS. 1 and 2 that on both sides of the stub lug 5, the grip part 1 each has a longitudinal recess 7 for receiving the fingers of the user.
  • the razor or thinning knife is characterized by its good ergonomic properties and can also be used as a so-called disposable razor or thinning knife.
