Definitions

  • the invention relates to a wet shaver with a handle, at one end of which a shaver head is formed.
  • a razor blade unit is arranged on this razor head.
  • a razor blade unit is to be understood as an essentially elongated plastic body in which a single or double razor blade is embedded in a non-detachable manner.
  • a handle at one end of which a razor blade unit is arranged on a razor head by means of a corresponding fastening mechanism, are known.
  • the handle is usually always designed in the manner of a rod.
  • the razor head at one end of the rod can be widened to accommodate the attachment mechanism.
  • the razor blade unit is usually attached to the handle such that the cutting edges are substantially perpendicular to the longitudinal center line of the handle.
  • the handle is simply an elongated, straight rod with a substantially uniform cross section, this is ergonomically unfavorable because the grip position by the user is not optimal. Poor handling of the razor makes shaving difficult.
  • solutions are known from the prior art in which the Ergonomic properties have been improved so that the handle is curved in its longitudinal median plane. This essentially S-shaped vibration means that the handle can be placed well in the palm of the hand and held with a thumb.
  • the optical design capability is very limited, since on the one hand a straight, elongated rod can be modified practically only with regard to the coloring, and on the other hand the shape of the S-shaped handle is limited by the desire to adapt it to the palm of the hand.
  • the object of the invention is to improve the ergonomic properties of a handle in a wet shaving apparatus of the generic type in order to achieve a quieter and more uniform guidance of the wet shaving apparatus.
  • wet shaver should be improved in terms of its optical design options in the area of the handle.
  • the invention proposes that the handle be curved in the direction pointing in the functional position toward the surface to be shaved.
  • the wet shaver formed according to the invention can only be used by the user in a certain grip position. Even slight hand rotations cause the razor blade unit with the cutting edges to be turned away from the skin.
  • the handle shape encourages the user to adopt an almost fixed shaving position. This makes the shave much smoother.
  • the wet shaver according to the invention is also simpler and therefore more economical to manufacture.
  • wet shaver shape according to the invention offers the possibility of further optical design, since it is only defined with regard to its curved shape.
  • the handle be curved in a uniform arc over its entire length. Due to this uniform design, the hand position is fixed in a kind of end position, which supports a quiet razor guide.
  • the curvature is such that the radius of curvature becomes smaller in the area of the razor head.
  • the handle on the outside of the curve comprises a substantially widened, flat surface.
  • this can be achieved by oval or rectangular cross sections, but also by several round profiles. It is essential that a wide contact surface for the fingers of the user is provided in the area of the outside of the curve.
  • the handle has an essentially triangular cross section, the tip of the triangle forming the inner edge of the curve.
  • a triangular base thus represents a support for the fingers, while a triangular tip represents the point of attack for the operator's thumb, which presses the handle against the fingers and thus fixes them. Due to the small contact area for the thumb, the wet shaver can be held securely with little force. It is not important that the triangular cross section has sharp corners, these can also be rounded.
  • the handle has a gag-like thickening at the rear end. This toggle-like thickening allows the user to place the handle more in the palm of the hand and thus prevent lateral tipping even better.
  • FIGS. 1 to 4 of a wet shaver each have a one-piece handle 1, which can be formed from plastic, metal or another suitable material.
  • a razor head 2 is formed, which includes the mechanical fastening units for a razor blade unit 3.
  • the razor blade unit 3 is fastened to the razor head 2 in a manner known per se and is essentially an elongated plastic housing in which a single or double razor blade is inserted in a non-detachable manner.
  • These razor blade units 3 are frequently replaced, for which purpose the wet shaver can have a release device in the form of a button or the like.
  • the razor blade units 3 can also be connected to the wet shaver handle 1 via a tongue and groove connection.
  • the handle 1 has a curvature in the direction in which the handle points in the functional position relative to the surface to be shaved.
  • there is a curvature compression in the area of the razor head ie the radius of curvature is reduced there.
  • the wet shaver is used by the user placing his fingers on the top of the shaver while fixing the wet shaver on the bottom of the handle 1 with the thumb. Then the hand is turned so that the razor blade unit 3 can be guided over the surface to be shaved in the functional position. This hand position, which inevitably results from this, is such that a calm and even shave can be performed.
  • FIGS. 1 and 2 also has a gag-like thickening 4 which is formed at the rear end of the handle.
  • the handle according to this embodiment has a substantially oval cross section.
  • FIGS. 3 and 4 has a rectangular or triangular cross section.
  • the handle has a substantially flat upper contact surface for the fingers.
  • the handle 1 has an arcuate curvature 6 that is uniform over the length of the handle. This wet shaving apparatus is also to be used in a corresponding manner as described above and ensures smooth guidance.
