Definitions

  • the invention relates to a razor with a shaving head with a film-like upper knife and a lower knife abutting against it, both of which have a curved cutting area with respect to an axis, with a motor-driven drive device for the lower knife, which has a block-shaped drive part has, with which the lower knife at least one movement parallel to the direction of the axis can be given, and with a hair dust seal made of elastic material, which is hood-like and trough-like and is arranged around the block-shaped drive part and four side walls and one the four side walls on their Limiting ends facing the lower knife, having a passage opening for an output section of the drive part, with which the hair dust seal is connected to the drive part, and one of the four side walls on their side facing away from the lower knife Has ends bordering edge area with which the hair dust seal rests against a housing-stationary zone.
  • a shaver according to the type mentioned above is known for example from EP 0 480 499 A1.
  • the hood-like and trough-like hair dust seal has side walls which are essentially continuous and mainly flat.
  • the hair dust seal it has been shown that when the lower knife is driven, the hair dust seal that is also moved in the area of its larger side walls running parallel to the direction of the axis executes transverse movements to these side walls with relatively large amplitudes and therefore practically acts like a diaphragm of a loudspeaker the hair dust seal causes a relatively high level of noise. This is annoying, which is why such a formation of a hair dust seal has proven to be unfavorable in practice.
  • the invention has set itself the task of avoiding the difficulties mentioned above and to achieve a formation of a hair dust seal in a shaver according to the type mentioned in the first paragraph, in which there is practically no or very little noise.
  • the invention is characterized in that the hair dust seal has a gradation extending over all four side walls and that the gradation has an undulating course at least in the two opposite side walls running parallel to the direction of the axis.
  • the wall sections of those side walls of the hair dust seal in which a gradation having a wavy course is provided, can execute a relative movement made possible by the wavy gradation, which mainly takes place parallel to the respective side wall and which results has that practically no or only very small movement components running transversely to the wall sections occur within the wall sections.
  • the drive device in the area of the hair dust seal does not have a block-shaped drive part, but a pin-shaped drive part, and the hair dust seal is not a hood-like and trough-like design, but instead has a rotationally symmetrical, frustoconical design.
  • This hair dust seal is also provided with a circumferential gradation. However, this gradation always has the same axial level along the entire circumference.
  • the gradation of the hood-like and trough-like hair dust seal of a shaving apparatus according to the invention points at least in the two parallel to the direction of the axis running opposite side walls of the hair dust seal on a wavy course.
  • the gradation can have an essentially sinusoidal shape, for example, in its areas with a wavy shape.
  • the price has proven to be particularly advantageous if the gradation is sawtooth-shaped in its areas with a wavy course. In the case of such a sawtooth-shaped course of the gradation, a particularly low level of noise was found in practice by means of a hair dust seal in such a shaving apparatus.
  • edge of the hair dust seal rests in a recess on the inside of the housing that is open to the shaving head and the edge region of the hair dust seal presses against an area of the shaving head with an edge region zone that is exposed to the deposit.
  • the edge region of the hair dust seal is used not only for fastening the hair dust seal, but also as a damping element which prevents mechanical vibrations between the shaving head and the housing of the shaving apparatus and thereby prevents disruptive noise.

With regard to the drive device 76, reference is made to EP 0 480 499 A1, from which a shaver 1 with such a drive device is known and whose disclosure content is hereby incorporated by reference by reference to the same (herewith incorporated by reference).
  • the drive device 76 has a motor 78, to the rotatably drivable motor shaft of which is not visible in FIG. 2, a rotatably drivable eccentric 79 is connected, from which an eccentric pin 80 projecting eccentrically with respect to the shaft of the motor 78 protrudes.

  • the shaving apparatus 1 has a hair dust seal 107.
  • the hair dust seal 107 consists of an elastic material, namely rubber.

Furthermore, the hair dust seal 107 has an end region 113 which delimits the four side walls 108, 109, 110 and 111 at its ends facing the lower knife 73 and has a passage opening 112 for the beating section 77 of the drive part 75, with which the hair dust seal 107 is connected to the drive part 75 is.
  • the drive part 75 has a closed circumferential groove 114, into which the hair dust seal 107 is inserted with its wall sections of the end region 113 surrounding the passage opening 112. Furthermore, the hair dust seal 107 has an edge region 115 which delimits the four side walls 108, 109, 110 and 111 at its ends facing away from the lower knife 73 and by means of which the hair dust seal 107 rests against a housing-stationary zone.
  • the hair dust seal 107 lies with its edge region 115 in a shoulder 116 on the inside of the housing and open towards the shaving head 10. Furthermore, the dimension of the edge region 115 in the height direction of the shoulder 116 is selected such that the edge region 115 of the hair dust seal 107, with an edge region zone 117 exposed relative to the shoulder 116, presses against a region 118 of the shaving head 10 or its shaving head frame 12. As a result, mechanical vibrations between the housing 2 of the shaving apparatus 1 and the shaving head 10 or its shaving head frame 12 are prevented, so that no noise caused by such vibrations can occur and a quietly working shaving apparatus is obtained.
  • the hair dust seal 107 is fastened in the shaving apparatus 1 with the aid of two resilient brackets 119 and 120.

  • the gradation 126 is sawtooth-shaped in its areas with a wavy course.
  • the undulating course could also be essentially sinusoidal.
  • the gradation 126 can also have a wavy shape in the two shorter side walls 110 and 111 of the hair dust seal 107.
  • the provision of the step 126 with a wave-shaped course means that the wall sections of the area-wide side walls 108 and 109 separated by the step 126 with a wave-shaped course practically only perform movements parallel to these wall sections, so that these side walls 108 and 109 the hair dust seal 107 has no effect like an acoustic membrane. This ensures that the hair dust seal 107 causes only a particularly low level of noise, which is also advantageous with regard to the implementation of a particularly quiet shaver with such a hair dust seal.
  • the invention is not restricted to the exemplary embodiment described above.
  • the invention is also applicable to a razor in which the lower knife does not perform a combined back and forth movement and swiveling movement, but only a pure back and forth movement.
  • other forms of hair dust seals are also possible, for example a hair dust seal with a gradation with an undulating course everywhere.
  • Such a hair dust seal can also have two such gradations, which are arranged one above the other.
