Definitions

  • Dry shavers with two or more shearheads arranged in parallel relation, to achieve a closer shave, are known.
  • the first shearhead has a pulling action on the skin and the second shearhead follows over the stretched skin.
  • the hair or stubble tends to assume positions vertical to the skin surface and also projects more out of the pores, which makes it possible, that the stubble cut by the advancing shearhead may be cut deeper by the following shearhead.
  • the invention consists of a multiple head dry shaver, comprising at least two independent shaving heads or assemblies, which shaving heads are not in parallel relation to each other.
  • shearheads are taken into consideration, having an outer stationary cutter operating with a reciprocable inner cutter in such a way that the shearing action takes place not openly, but within the guard, which is at the same time the outer cutter.
  • Such constructions, where the outer cutter forms a guard make it possible to press the shearhead harder against the skin, without injury and therefore they allow a greater stretching of the skin.
  • the slots in these outer cutters are continuous, as such an arrangement takes good care of the skin, compared with interrupted slots or guard openings which are arranged like a sieve.
  • Such sieve cutter guards will bring positively into vertical position the hair that enters the sieve holes, however they exert an unpleasant pressure on the stubble which does not enter the holes.
  • Continuous slots have the disadvantage, that strong, rather horizontal stubble cannot be suificiently pulled up to a vertical position and therefore the inner cutter cannot cut them, as long as the slots are guided over the stubble in the same direction as the stubble lies on the skin.
  • Such disadvantages associated with outer cutter guards, where the slots go right through, are eliminated by the present 2 invention.
  • the strong stubble which goes right through the first shaver head without being cut is pulled vertically by the inclined position of the second shearhead.
  • This second shearhead is at an angle with the line of motion of the first shearhead and therefore the hair has no Way to escape the inner cutter.
  • Stubble that goes in an inclined position through the opening of the cutters may be caught more securely and lifted up more cautiously with shearheads having continuous slots than with those having interrupted slots.
  • the effect is similar to the effect of a plough, as the skin is very much stretched apart.
  • the skin may be raised by the shearheads, wherever desired, which is an advantage for certain growth of hair, as it may pull up the stubble to a different position.
  • the shearheads may be of a straight construction, or curved lengthwise. Those shearheads with the cutting part curved lengthwise and concave have the further advantage with an inclined arrangement of the shearheads, that according to the angle with which the shaver touches the skin, either the part where the shearheads are further apart or the part where the shearheads are nearer together can be used, as desired.
  • Such lengthwise curved shearheads have the added advantage that they stretch the skin to an inside arch and with it the skin is stretched in two directions for the trailing shearhead.
  • This inclined relation of the shearheads governs the stretching of the skin according to the angle with which they touch the skin and with it also the crosswise stretching of the skin works in a different angle, according to the direction in which the shaver is moved. The result is, that even with moving the shaver back and 3 forth in the same direction the stubble is pushed up in difierent directions.
