Definitions

  • the invention relates to a dehairing device with a housing and at least one clamping device formed by a helical spring for detecting the hair to be removed and a drive for moving the clamping device relative to the hair and the housing, the housing having a rotatably mounted Head, in which the helical springs with an essentially radial axis and in this direction compressible and expandable is arranged.
  • Motor-operated hair removal devices have become known in various designs.
  • Depilatory devices that operate using helical springs capture the hair between the individual passages or coils of the springs when the springs are compressed, and when the springs are compressed in the axial direction, the hair is gripped.
  • the compression of the springs in the axial direction of the helical springs can be done by moving a free end of such a spring over a cam track, the cam track having a plurality of cams which cause the compression of the springs.
  • the compression of the helical springs must be carried out exactly in such a way that the pressing force between adjacent windings of the springs is sufficient to grasp hair reliably.
  • the invention now aims to provide an embodiment of the type mentioned at the outset, with which it is possible to ensure exact adjustment of the setting of the helical springs, even in the case of large series and correspondingly specified tolerances, during production, so that this is ensured that when the springs are compressed, hair can actually be grasped to a sufficient extent for epilation.
  • the training according to the invention consists essentially in the fact that the helical springs are each arranged between jaws of a pair of pliers, the pivot axes of which are mounted in the head in a plane that is essentially normal to the axis of rotation, that the free legs of the pliers are on a ring rib ⁇ shaped fixed cam are supported, the cam having different widths in the radial direction over its circumference and is trapezoidal in cross-section at least in the area of its broadest design, and that the head is axially adjustable on the axis of rotation.
  • this construction results in the possibility of designing the control curve interacting with the free legs of these pliers in a simple manner so that the adjustment is made possible. It is sufficient for this control curve to be trapezoidal in cross section, at least in the region of its widest configuration, so that a position can be set by simply adjusting the head in the axial direction, in which a position on the control curve when the free legs run up reliable compression of the springs is achieved by exerting the corresponding clamping force between adjacent turns.
  • Such a simple adjustment in the axial direction can either be carried out against the force of an additional spring or, by utilizing the spring force of the helical spring, can also be easily accomplished in series production by simple axial displacement and fixing in the displacement position without additional securing.
  • the adjustment in the axial direction can be effected, for example, by a self-locking nut.
  • the design is advantageously such that the free ends of the legs of the pliers are formed by bolts or pins which resiliently abut the flanks of the control cam.
  • Such a design naturally results in additional tolerances which, however, can easily be compensated for due to the adjustability of the head in the axial direction.
  • the bearing of the pliers carrying the helical springs can advantageously be designed such that the head has a substantially disk-shaped carrier with openings for the pliers and recesses for receiving the pivot axes of the pliers, and that a cup-shaped outer part with guide devices, in particular combs, with the carrier under Inclusion of the pivot axes of the pliers can be connected, the assembly being particularly facilitated by the measure that the carrier of the guide devices can be simply clipped on.
  • simple components which can be assembled quickly and safely, can be used, since there is still the possibility in series production to compensate for the existing tolerances by axially displacing the head and adjusting it in the displacement position.
  • the design is advantageously made such that the head is rotatably connected, in particular pressed, to a bearing sleeve, and that a self-locking nut is screwed onto the axis of rotation and against the outer end face the bearing sleeve, in particular with the interposition of a sliding washer.
  • a bearing sleeve can be designed, for example, as a highly wear-resistant component, in particular a ceramic component or made of plastic or sintered metal, as a result of which the components interacting for the adjustment exhibit little wear even during long operating times.
  • the design is advantageously made such that the head is connected to the rotary drive via a coupling, in particular a claw coupling.
  • the design is such that the control curve has at least two, preferably three, constrictions of the cross-sectional profile distributed over its circumference, the beginning and end of which in the circumferential direction on the inside and outside each of a Ge - Raden are limited, whereby the opening and closing movement of the springs can be controlled accordingly even at high speeds of the rotating head.
  • Hiebei is the training Education preferably made such that the flanks in the region of the constriction form a smaller angle at their points of smallest width with a straight line parallel to the axis than at the wider areas of the cross-sectional profile of the control curve.
  • the design is preferably such that the central angle over which the wide areas between adjacent constrictions of the cross-sectional profile extend is at least 2 times, preferably at least 3 times the central angle between the beginning and end of a constriction, so that during the movement the springs are in the rotating head in the compressed state for a sufficiently long period of time.
  • FIG. 1 shows a side view, partly in section, through a depilatory device according to the invention
  • 2 shows an enlarged view of the hair removal device according to the invention in the direction of arrow II
  • 3 shows an enlarged scale a section along the line III-III through the head of the hair removal device according to the invention with a non-compressed spring
  • 4 shows, in a representation similar to FIG. 3, a section along the line IV-IV of FIG. 2 in a position with compressed helical spring
  • 5 shows a plan view of the control curve
  • Figure 6 shows a section along the line VI-VI of Figure 5.
  • a motor 3 is mounted, which one by one via a gear arrangement 4 and a dog clutch Axis 5 drives head 6 rotatably to a rotation in the direction of arrow 7.
  • a plurality of helical springs 8 are mounted, which extend in an essentially radial direction with respect to the axis of rotation 5, the longitudinal axes 9 of the individual helical springs being extended extend essentially parallel to the surface 10 of the rotating head 6.
  • the coil springs 8 are arranged in the radial direction along their longitudinal axis 9 in a compressible and expandable manner, a coil spring 8 being shown in the expanded state in the illustration according to FIG.
  • adjacent coil springs 8 are shown in the compressed state on the one hand and in the expanded state on the other hand.
  • the compression of the helical springs 8 during their rotational movement about the axis 5 takes place in the embodiment shown essentially by the fact that the helical springs 8 are mounted in pincer-shaped jaws 11 which can be pivoted relative to one another about a schematically indicated axis 12.
  • the free legs of the pliers 11 are supported on a fixed annular rib-shaped control curve 13, the control curve having a different width in the radial direction over its circumference, as will become clearer in particular from the following figures.
  • the rotating head is supported by a bearing sleeve 14 schematically indicated in FIG. 1, 8 guide devices in the form of combs 15 also being rotatably mounted between the compressible coil springs.
  • the head 6 is mounted on the axis of rotation 5 such that it can be adjusted in the axial direction, as is indicated by the double arrow 16.
  • the combs 15 are substantially parallel to the longitudinal axes 9 of the
  • Coil spring 8 arranged.
  • the storage for the compressible coil springs 8 is more clearly evident from the representations according to FIGS. 3 and 4.
  • the coil springs 8 are each mounted in the jaws 11 of a pair of pliers with the interposition of a damping element 25, the individual jaws 11 being able to be pivoted relative to one another about the pivot axis 12.
  • the free legs 17 are formed by bolts or pins which run on the fixed annular rib-shaped control cam 13, the pliers being located in the area of the smallest radial extension of the control cam 13 in the illustration according to FIG. 3, so that the spring 8 is open.
  • the trapezoidal cross section of the control cam 13 is clearly visible in the region of its greatest radial extent.
  • the pliers which carry the compressible springs 8, are mounted in an essentially disk-shaped carrier 18, which has corresponding receiving openings 19 for the pliers 11.
  • This disk-shaped carrier is connected in a rotationally fixed manner to the bearing sleeve 14, the bearing sleeve 14 being mounted on the axis or shaft 5.
  • the disk-shaped carrier 18 is overlapped by a pot-shaped outer part 20, which carries the guide device in the form of combs 15, the pot-shaped outer part 20 being connected to the carrier for the pliers 11 via a latching connection 21.
  • the rotating head is fixed on the shaft 5 by means of a self-locking nut 22 with the interposition of a slide washer 23.
  • a self-locking nut 22 By corresponding axial displacement of the rotating head relative to the fixed control cam 13 in the sense of the double arrow 16 by screwing the nut 22 on accordingly, the nut 22 can be achieved rotating head exactly to position the cam 13 in such a way that, in the closed position shown in FIG. 4, the hair to be removed can be gripped securely. It is thus possible to compensate for tolerances in the production of the individual components, since the closing movement and the closing path of the jaws 11 are easily adjustable due to the trapezoidal cross section of the control cam.
