Definitions

  • the present invention relates to an epilator and more particularly to an epilator comprising a helical spring made from a rectangular, square or trapezoidal wire.
  • depilatory devices comprising a helical spring which operates according to the principle of pinching the bristles between the turns of the spring when the latter is bent and forms a compression zone on one side.
  • This type of device is generally equipped with a motor that drives the helical spring in a rotational movement that alternately compresses and lengthens the turns of the spring in a curved position, the spring being rotated by a motor.
  • This type of device is notably disclosed in the documents US Patent 4,524,772 as well as FR-2 627 362 .
  • a helical spring is conventionally made from a circular section wire.
  • the force of this spring is therefore essentially conditioned by the material used and the diameter of the wire with which it is made; furthermore, the distance between the surfaces or pinch points which are in fact the contact point between two adjacent turns and the skin is also determined by the diameter of the wire (see Fig. 3).
  • the higher the diameter of the wire the greater the pinch distance from the skin is large, and more hair removal is painful.
  • the present invention aims to provide a coil spring hair removal device whose spring force is independent of the nip distance from the skin and whose section of the wire is such that it allows a pinch of the peas as close as possible skin
  • the present invention discloses an epilator comprising a casing and a helical spring prestressed in curved configuration and rotatably mounted on said housing, and a motor coupled to said spring for driving the spring, when using the epilator, in a rotational movement, imparting to said spring a tangential movement with respect to the skin to be epilated by generating a continuous movement of said turns from a spacing orientation to a compression orientation characterized in that said coil spring has turns made from a wire of substantially rectangular, square or trapezoidal section, said spring forming in the prestressed state a diverging zone where the turns are spaced from each other and a convergent compression zone where the turns are pressed against each other for taking and removing hair from the skin.
  • said turns comprise notches for combing the depilatory hairs.
  • the coil spring is made of stainless steel.
  • Figure 1 shows the coil spring made from a wire of substantially rectangular section.
  • the square and trapezoidal sections are not represented. Notches are also shown in detail on the magnifying glass of this figure.
  • Figure 2 shows several views of the epilation spring rotatably mounted on its support.
  • the presence of the motor is schematically represented in the case.
  • the details of the divergent and convergent zones are noted.
  • Figure 3 shows a hair removal spring with round section according to the state of the art or there is an undesirable distance between the pinch point and the skin.
  • FIG. 4 shows the pinching of the pile with the helical spring with wire of essentially rectangular section of the invention (slightly rounded corners due to manufacturing constraints) which makes it possible to pinch the pile over a large pinching surface, that is to say on a larger surface than those presented by the springs obtained from round wires of the state of the art (see Fig. 4) and flush with the skin.
  • Square or trapezoidal sections produce the same effect. The trapezoidal sections even make it possible to achieve a gripping surface wholly taking up the height of the section of the turn according to the prestressing curvature which is given to the spring.
  • the present invention discloses a novel hair removal device based on a helical spring hair removal element 1 in which the spring made with a round section wire has been replaced by a spring made from a wire of substantially rectangular section 2 or square.
  • a spring made from a wire of substantially rectangular section 2 or square We mean by essentially rectangular or square, a rectangle or a square with slightly rounded corners. These rounded corners are obviously due to manufacturing constraints because it is not desirable to have a wire with a rectangular section with a cutting edge.
  • the rectangular word must not be interpreted in the strictly geometric sense of the term.
  • the spring 1 made from a wire with a rectangular, square or trapezoidal section 2 makes it possible to decouple the force of the spring 1 from the pinch distance with respect to the skin 8 in the sense that it is possible to obtain powerful springs capable of to pinch a hair 9 directly at the root and in immediate contact with the skin 8.
  • the geometries of the rectangular, square or trapezoidal wire 2 form turns on a helical spring which have a position essentially perpendicular to the skin, knowing that the pinching is carried out at the outer width of the section of the wire used to make the spring.
  • the springs can be folded in different ways, as shown in particular in the document FR-2 627 362 or the document EP-B1-0 101 656 .
  • this type of spring is usually made of stainless steel or in another way not likely to oxidize.
