Definitions

  • the present invention relates to a curling iron with a handle region and a heatable working region, according to the preamble of claim 1.
  • the present invention therefore deals with the problem of providing for a curling iron of the generic type an improved or at least one alternative embodiment, by means of which the production of curls of different sizes is comparatively easily possible.
  • the present invention is based on the general idea of providing a curling iron with a handle region and a heatable attachment or work area to provide the work area with a round outer contour which has at least two sections with different radii of curvature and thus different surface curvature.
  • individual sections of the work area are heated, unheatable or even coolable, which helps reshape the hair.
  • the heatable sections are heated to a temperature that breaks up the chemi Customer Ties in the hair is suitable, whereas the unheated sections or the cooled sections have a temperature which allows a sufficient cooling of the hair, so that new and curling required chemical bonds can form in the hair.
  • heating systems customary for curling irons are conceivable, for example ceramics, heating elements, PTC heating elements, but also surface heating systems, for example thin-layer or thick-layer heating or radiation sources, such as, for example, infrared lamps.
  • Those sections that are not heated in a particular application may either be at a lower temperature than the heated sections because the heating element responsible for that section is not activated or even cooled by active cooling.
  • Active cooling can be accomplished, for example, by flowing through the respective section with a medium (eg air or water) or through a Peltier element.
  • the individual sections may either be thermally isolated from each other, for example by an insulating material disposed therebetween, or the individual sections are spatially separated, in which case the insulating medium would be air.
  • the curling iron according to the invention is particularly characterized in that at least two sections are provided with different curvature at the work area, so that when using the curling iron according to the invention a strand of hair to be formed first passed along a hot attachment section and then over a non-heated or even cooled section of the workspace.
  • the user has the ability to produce either curls of large diameter or curls with a small diameter. If, for example, large curls are to be generated, those portions of the working area are heated which have small radii or radii of curvature, whereas those portions with a large radius of curvature are not heated and subsequently used for cooling the hair and for forming new chemical bonds. Basically, the reverse approach applies to the generation of small curls.
  • the user thus knows that when she cools her hair strand at a section with a small radius of curvature receives a small curl diameter and vice versa.
  • the user can always use the curling iron described to pull it along the hair at the same speed, which is close to natural behavioral patterns.
  • the working area is formed in one piece.
  • a one-piece work area has a non-circular, but round outer contour, which has at least two sections with different radii of curvature. Preferably, at least four such sections are even provided on the one-piece working area.
  • all sections of the workspace are convex.
  • the working area is formed in two parts, wherein the two partial areas are separated by a slot and each of the partial areas has at least two sections with different radii of curvature.
  • a two-part attachment or work area may e.g. be designed on the basis of an essay of a so-called G-Curlers. Also in this work area you will find numerous different radii of curvature that can be used to reshape the hair.
  • the deformation of the hair can either be done as in the one-piece article, that is, the hair is exclusively on the outer contour, or it can also be the inner slot, which separates the two sections from each other, are used for hair shaping.
  • the slot may for example be S-shaped and have inner sections with different radii of curvature.
  • the radii of curvature of the inner sections that is, the sections lying in the slot preferably deviates from the radii of curvature of the round outer contour.
  • the working area has at least four partial areas with air gaps extending therebetween.
  • it is a so-called multi-part attachment, which makes it possible in particular to spatially separate heated, unheated or even cooled sections or partial areas.
  • the basic geometries can be largely identical to those of the one-part and two-part work areas.
  • the working area has at least six finger-like sections, which are arranged in a non-circular ring shape.
  • the individual work areas are very small, for example, formed in the manner of fingers or rods, and only touch each other linear.
  • At least individual sections or sections are adjustable in terms of their temperature by means of an adjustment.
  • a device-side preset e.g. be selected by means of a choice (rotary knob or slider).
  • curl size e.g. small-large or small-medium-large, depending on the selected position, the curling iron controls the required heaters sections or the work area and activates.
  • a manual selection of the individual heaters or heated sections or sections is conceivable.
  • an optical and / or haptic temperature display which informs a user of a temperature at a section and / or a partial area. This gives the user the opportunity to get immediate feedback on which areas of the work area are hot and which are cool.
  • this can e.g. be realized by a LED ring in the handle area.
  • red LEDs may indicate hot zones and blue LEDs may indicate cold zones.
  • Haptic would be conceivable that an extendable pin ring is present in the grip area.
  • extended pins can signal hot sections or portions of the workspace and retracted pins can signal cold sections.
  • thermochromic materials or coatings are used.
  • a ring in the grip area or near the grip area in the immediate vicinity of the working area of said material or said coating is attached. Since this ring has a different temperature in the vicinity of heated zones than in the vicinity of unheated zones or sections, this can be directly and easily visualized by means of the thermochromic properties become.
  • thermochromic materials that have different color change temperatures, the selection of the appropriate material depends on its location on the curling iron. Immediately at the work area, the sensible drive temperature will be higher than at the handle area.
  • the curling iron according to the invention offers the great benefit that the user does not have to adapt to the device in order to achieve a certain curling result, but rather that the user's curling iron can be adjusted. That is, from the natural usage behavior, for example, in view of a previously used to tempt the hair straightener, the user tends to prefer to pull the hair through the curling iron at a certain speed. If you want larger or smaller curls, you just need to heat or cool other sections of the work area, but your preferred pull-through speed can be maintained by the user. Moreover, since only those sections or partial area of the working area that are required for the hair shaping are heated, the curling iron according to the invention can be operated in an energy-saving manner.
  • a curling iron 1 according to the invention has a grip region 2 and an at least partially heatable working region 3.
  • the working area 3 now has a round outer contour in cross-section (see sectional plane AA) and at least two sections 4, 5 with different radii of curvature, the sections 4 having comparatively large radii of curvature and the sections 5 having comparatively small radii of curvature.
  • the individual sections 4, 5 can be heated, unheated or even actively cooled.
  • the individual sections 4, 5 of the working area 3 are in particular in the representations according to the Fig. 2 to 5 and 7 and 8 visible.
  • FIG. 2a to 2d illustrated cross sections through the work area 3, it can be seen that in these representations of the working area 3 is integrally formed.
  • the according to the Fig. 3 shown work area 3 is formed in two parts, similar in the manner of a Yin and Yang symbol, and thus has two sections 6, 7, which are separated by a slot 8.
  • Each of the subregions 6, 7 has at least two sections 4, 5 with different radii of curvature.
  • the slot 8 is S-shaped and has inner sections 4, 5 also with different radii of curvature.
  • each of these sections 6, 7, 9 or 10 each has at least two sections 4, 5 with large or comparatively small radius of curvature.
  • Fig. 5 is a work area 3 shown with a plurality of finger-like portions 12, which are also arranged in a non-circular ring shape. Between the individual subregions 12 is either a spatial distance, which provides for a corresponding insulation, or the individual subregions 12 are only linear, that is with a small contact surface, to each other.
  • Fig. 6 For example, the construction of such a portion 12 is shown with an internal heating element 13, which may be formed for example as a PTC heating element or as a ceramic heating element.
  • Curls of different sizes can therefore be produced, for example, with a curling iron 1 as follows: If, for example, large curls are to be produced, the hairs 14 to be formed are first heated above the section 5 with a comparatively small radius of curvature and then cooled above the section 4 with a comparatively large radius of curvature. In section 5, the previous bindings of the hair are thereby broken, whereas they are subsequently restored in a little severely curved shape over the section 4. Conversely, it is in the production of small curls, then, like this, for example, according to the Fig. 8 is shown, first over a section 4 with a comparatively large Curvature radius heated and then cooled over a section 5 with a relatively small radius of curvature and thus fixed in terms of their shape. It is important, however, that always that portion 4, 5 which is responsible for the final fixation of the hair 14, cooled, but at least not heated, in order to produce the corresponding molecular bonds in the hair 14 can.
  • the curling iron 1 can have an adjusting device 15, by means of which at least individual partial regions 6, 7, 9, 10 are adjustable. Also provided may be an optical and / or haptic temperature display 16 (see. Fig. 1 ), which informs a user of a temperature in a section 4, 5 and / or a subarea 6, 7, 9, 10 or 12.
  • the temperature indicator 16 may have, for example, red and blue LEDs, which stand for hot or cool sections 4, 5.
  • extendable pins could be provided which indicate hot sections 4, 5 of the working area 3 in the extended state and cooler or cold sections 4, 5 in the retracted state.
  • the thermochromic coating 17 which assumes a different color due to a temperature effect and thereby transmits an optical signal to the user.
