Definitions

  • the invention relates to a device for plucking hair with the features specified in the preamble.
  • a device of the type mentioned is known from EP-A-0 147 285.
  • an axis provided with disks or brushes is arranged parallel to the driven shaft, the disks or brushes engaging with part of their circumference between the disks of the associated plucking elements in order to clean them.
  • Devices of this type have a high construction cost, require a large number of different individual parts that have to be manufactured with high precision, and have an unfavorable energy balance due to relatively large frictional losses, particularly when controlling the tweezers effect of the disks, which is particularly the case with battery operation handheld small electrical appliances is preferred, adversely affects.
  • the invention provides a device of the type mentioned, which is described by the features in the characterizing part of claim 1.
  • the advantage of the invention lies on the one hand in the use of relatively few different components - correspondingly many structurally identical parts of the plucking head - on the other hand in the reduction of the friction caused by the spreading rollers, which at the same time clean the disks as plucking elements.
  • the exclusive use of circular, circumferentially closed and relatively closely spaced disks as plucking elements causes the skin to be held down during the plucking process.
  • claims 13 to 17 show an advantageous way of how, with the simplest construction, a special effort, in particular during the closing process of the panes and of course during the entire opening phase of the panes, energy losses due to friction and additional clamping and bending forces can be avoided.
  • the device for plucking hair shown in Fig. 1 has a housing 1 serving as a handle, in the lower end of which a motor 2 is attached. At the opposite end of the housing 1, a shaft 3 is rotatably mounted, which is set in rotation by the motor 2 via a toothed belt drive 4. Instead of the toothed belt drive, a toothed wheel gear or a simple belt drive can also be used, as is known per se.
  • the wave 3 has a square cross section (Fig. 2). A number of circular, circumferentially closed disks 5 are lined up on the shaft 3 and are held in a basic position normal to the shaft 3 and at a certain distance from one another by spacer rings 6; the disks 5 thus rotate with the shaft 3.
  • the disks 5 form paired plucking elements 7 and are clamped together with the spacer rings 6 in the longitudinal direction of the shaft 3 by means of a nut 8 or the like, arrow A.
  • a nut 8 or the like, arrow A In the area between the motor 2 and the shaft 3 an axis 9 is fixedly mounted in the housing 1 parallel to the shaft 3, on which spreading rollers 10 are freely rotatably mounted, which engage with part of their circumference between the disks 5 of each plucking element 7, as can be seen from FIGS. 1 and 2.
  • the disks 5.1 of the pair of disks 12 are provided on the opposite surfaces 5.2 with spacing reductions 13 in the form of ribs 14, which are formed by retracted beads.
  • the ribs 14 are curved, following the radius of the disks 5.1, and their length is dimensioned according to the desired closing time of each plucking element 7. Their distance 15 from the edge of the disk is greater than the engagement depth 16 of the associated spreading roller 10.
  • the ribs 14 lie firmly against one another, and in the opposite area the disks 5.1 are kept at a distance by the spreading roller 10.
  • the plucking element 7 is open for entry the hair to be plucked.
  • the spreading roller 10 gets into the free space 17 outside the ribs 14, the disks 5.1 tilt around the ribs 14 as a joint and the diametrically opposite edge zones of the disks 5.1 are pressed against one another by the tensioning force, arrow A.
  • the discs 5.3 are again combined as disc pairs 18 to pluck elements 7 and also with the aid of spacer rings 6, which are now also fitted between the discs 5.3 of each disc pair 18, on the shaft 3 with a square cross section pushed on and clamped against each other with the nut 8, arrows A.
  • the spacer rings 6 have an inner flat area 19 which ensures the position of the disks 5.3 in their open position normal to the longitudinal direction, and partial bevels 20 in the outer area which deform the disks 5.3 allowed with inclination against the shaft 3.
  • two spacing reductions 13 offset by 180 ° are provided, which are designed as embossed deformations 21 of an edge region of the disk 5.3 and have a flat surface 22, which is directed parallel to the inner disk surface 5.4 and faces in and against the direction of rotation of the disk Disk 5.3 are each provided with a chamfer 23.
  • the spacing reductions 13 are offset by 180 ° on each disk 5.3 and lie opposite one another on both disks 5.3 of the disk pair 18.
  • the plucking device works as follows: In the starting position of the plucking element 7, both discs 5.3 are directed parallel and are normal to the shaft 3. Although the spreading roller 10 also grips here with part of its circumference between the discs 5.3 of the associated pair of discs 18, it has little or no contact with the washers 5.3. In this position, which can be seen in FIG. 5, middle plucking unit, the plucking element 7 is open for taking up hair.
  • each pair of disks 24 only one disk 5.3 is provided with embossed deformations 21 as distance reductions 13 according to FIG. 5, while the other disk 5.4 is made flat.
  • FIGS. 8 to 12 A further, very advantageous variant of the form-fitting holding of the disks 5.5 of the plucking elements 7 on the shaft 3 is shown in FIGS. 8 to 12, which makes it possible to reduce the effort required for spreading the disks and thus to reduce the energy requirement and wear with simplified Adjustment and unproblematic cross-country properties.
  • the holder essentially consists of the bearing segments 25 shown in FIGS. 8 and 9, which have a pocket 27 in their central cuboid part 26 and two laterally projecting arms 28 of smaller thickness, the mutual distance a of which is dimensioned such that the bearing segment 25 can be plugged onto the shaft 3 with its square cross section. As can be seen in FIG.
  • tongues 29 are provided on the inner cutout 30 of each disk 5.5, which is adapted to the outer dimensions of the bearing segments 25, which tongues are in turn adapted to the dimensions of the pockets 27.
  • the associated dimensions are chosen so that the tongues 29 are relatively loose and movable in the pockets 27 and the disks 5.5 can easily tilt against each other, as far as the Allow spreading rollers 10 according to FIG. 11 and insofar as it is necessary for the opening and closing of each of the pair of disks 5.5 of the corresponding plucking element 7.
  • the tongues 29 functionally represent journals about which the disks 5.5 are tilted if they come into the region of the spreading rollers 10 in the course of the rotation with the bevels 23 of the embossed deformations 21 and the associated surfaces 22. It is only when the opposite surfaces touch that a significant force is required to spread the disks 5.5; however, it is only as high as the safe holding and pulling of the hair requires. There are no additional clamping and bending forces.
  • bearing segments 25 as identical parts which can be staggered in pairs allows the plucking elements 7 to be tightly nested together with the desired 90 ° offset of the spacing reductions 13, as a result of which large threading openings and minimally inactive zones can be realized; the structural design of the bearing segments 25 is not critical with a minimum total tolerance for the functionally important size of the gap between the disks 5.5, FIGS. 11 and 12 show these relationships, with FIG. 12 in particular showing the nested summary of the bearing segments 25.
  • a comb 32 can be fitted in the opening 11 of the housing, which engages with its prongs 31 between the discs 5 arranged in pairs and serves as a hold-down device for supporting the skin and for orienting the device during the plucking process.
