Definitions

  • the invention relates to the general field of hair care devices, which means devices or additional devices for shaping and drying the user's hair.
  • the group of hair care devices includes, for example, hair dryers, rounders, harmonic air drying hoods, warm air dry brushes, electricity-independent, gas-operated curling irons or curling brushes, and electrically operated curling irons or curling brushes.
  • Additional devices are, for example, attachments for hair dryers and hot-air brushes, such as diffusers, air-flowable additional brushes with different diameters, or curlers, which can be designed to be heated, for example, by means of warm air or by means of a separate standing device.
  • the invention is based on a winding body for hair care with a carrier element on which means are provided for guiding a plurality of webs arranged about a longitudinal axis of the carrier element, the webs being able to be brought into different positions by means of adjusting means in order to form a body with a different outside diameter.
  • the electrical steam styling rod of DE 2529026 AI has a hollow cylindrical winding body with a plurality of semicircular tube segments which are rotatably arranged on the outer wall of the heating tube as spreading lamellae.
  • the lamellas should not be designed as short circular arc sections, but should be semicircular in the optimal solution, ie bent by 180 °.
  • FIGS. 1 and 2 of this published specification shows, there is a form-fitting contact of adjacent slats in every position. tioning, i.e. not possible with all adjustable diameters of the winding body. Due to a drawing incorrectness, the lamellae of FIG.

  • the known winding body achieves a not particularly good approximation to a circular cross section - for any diameter.
  • This known embodiment has only a low stability with respect to radially acting forces, such as those which occur in practice when rolling up and shaping hair. A deformation of the winding body during use represents a significant impairment of the value in use.
  • the hair curler of US 3583409 A consists of several circular segments which are connected via lever arms to an axially displaceable carrier element arranged inside. Due to the special arrangement, an axial movement of the carrier element causes a radial movement of the individual segments. Although this arrangement may be appropriate for hair curlers, it is unsuitable for other applications, for example as an air-flow attachment for warm air dry brushes and the like. On the one hand, the actuation of this spreading mechanism requires free access to the inside of the hair curler, on the other hand, the axially displaceable carrier element and the lever arms represent a considerable flow resistance in the case of air-flowed brushes, so that their effectiveness drops.
  • this hair curler due to the structural design of this hair curler, there are more or less large slots between the individual segments depending on the set diameter, which are in any case extremely disadvantageous for brushes through which air flows, since the amount of air emerging from the brush through which air flows is essentially unaffected. should be dependent on the set diameter of the winding body.
  • the inner wall of the hair curler of the known US patent can be covered by an elastic layer so that the slits between the individual segments are closed, but this elastic layer poses problems with regard to the different demands due to the high demands on the elasticity at different diameters Durability on.
  • the known hair curler can only be set in two stable positions of different diameters. A continuous or quasi-continuous setting of intermediate positions is not possible.
  • the invention is based on the object of specifying a winding body which is also suitable for use in warm air devices, for example as a curling brush.
  • the winding body should be structurally simple in large series, in particular made of injection molded parts made of plastic, have sufficient stability even with larger axial dimensions and a shape which is closed for each diameter and approximated to a circular cylinder jacket.
  • This object is achieved by a winding body with the features mentioned in the introduction, in which each web has a recess over its longitudinal extent, with which the sections of an adjacent web are positively connected in each positioning of the webs. This measure advantageously ensures a closed shape of the winding body for each diameter, and sufficient stability is also provided by the positive connection of adjacent webs.
  • the form-fitting connection of the webs of the winding body provides the prerequisite for the winding body to have an at least approximately circular-cylindrical outer jacket for each diameter due to a corresponding profiling and shaping of the webs.
  • the fact that the webs are accommodated in rotary bearings at both ends of the carrier element ensures a simple, constructive structure of the wobble body.
  • the space between the bearing points is free and therefore does not represent an increase in the flow resistance of the winding body.
  • a rotary bearing is designed as a bearing with open bearing pans, at least one pin of the webs on a segment of the carrier element in the form of a segment of a circle and on an annular wall of the Positioning means is stored, the possibility is created in an extremely advantageous manner to hold the winding body together only by means of snap connections.
  • the measure of arranging an axis of rotation of the individual webs in the region of an end section of a respective web has the advantage that the webs can additionally be supported on the carrier element.
  • the embodiment that the axis of rotation is arranged radially offset outside the profile of the web is extremely advantageous.
  • each web has a pin in the region of a central section, which engages in each case a guide curve of the adjusting means, which in turn is fixed rotatably on the carrier element, makes it extremely easy to adjust the webs for setting different diameters of the winding body concerned.
  • a particularly advantageous embodiment of the known winding body which is already suitable in itself for solving the stability problems of known winding bodies, consists in that each web is axially displaceable by a dimension A with respect to the longitudinal axis of the carrier element.
  • the adjusting means are provided on one end on the carrier element and support means for radially fixing the webs on the other end on the carrier element, the webs are positively fixed at both ends in the radial direction for each diameter of the winding body, which increases the stability of the winding body in an extremely advantageous manner.
  • a particularly advantageous embodiment of the support means consists in providing a toothing arranged in the radial direction on each web, which toothing engages in an edge of a tube region.
  • each web consists of three longitudinal strips arranged essentially in an arc shape with respect to one another, which are connected to one another by transverse webs.
  • the possibility of a specific profile of the webs is created, which allows the winding body to have an essentially circular-cylindrical outer jacket for each diameter.
  • the winding former can also be used as a hot air brush as an attachment for a warm air generator.
  • the carrier element has a tubular section with peripheral openings which cooperate with openings formed between the transverse webs for the purpose of air outlet. Because the crosspieces are provided with bristle-shaped extensions, there is the possibility of can also be used as a brush.
  • each web is supported on an adjacent web over the entire longitudinal extent, which leads to an unexpectedly high stability of the entire winding body.
  • this measure prevents warm air, which may flow through the winding body, from flowing out to a greater extent through gaps which otherwise occur between the webs when the winding body is larger in diameter. The warm air flowing through the winding body can escape for each diameter of the winding body only through the openings, which may be provided between the transverse webs.
  • the underside of one longitudinal bar advantageously has an adaptation to the profile of the top of the further longitudinal bar. This ensures that adjacent webs can lie flush against one another in the case of setting the small or the smallest diameter of the winding body. With regard to stability, it is advantageous that a longitudinal edge of the further longitudinal strip is supported on the outer jacket of the tubular section in every positioning of the webs.
  • the longitudinal strips slide more and more in front of the openings in the tubular section, so that the flow resistance for the warm air emerging from the winding body increases to a certain extent.
  • This measure ensures in an extremely advantageous manner that the air throughput through the winding body is essentially unaffected by the respectively set diameter of the winding body.
  • the drying capacity of a hot air device for hair care equipped with such a winding body is thus largely independent of the diameter of the winding body set in each case and, if available, can be precisely controlled with the switching means provided on the device for varying the speed of a fan motor and for varying the Power of an electric or gas-operated heater can be set.
  • the adjusting means has two-dimensional guide curves that run in a plane perpendicular to the central longitudinal axis.

  • a structurally particularly simply constructed, extremely stable winding body is specified.
  • the thrust guides are advantageously designed as chambers in which sections of the Bridges are positively guided. It is particularly advantageous to solve the problem of stabilizing the webs over their entire length is the fact that the webs are guided at an acute angle, in particular at an angle between 10 ° and 80 °, preferably at one angle! of approximately 45 ° with respect to the longitudinal central axis.
  • the webs are moved not only in the radial direction with respect to the central longitudinal axis of the carrier element, but also in the axial direction.

  • inclined surfaces or bottoms are formed on both ends of the support element, on which guide surfaces of the webs are supported with corresponding bevels.
  • the individual webs can also be supported extremely advantageously in that additional oblique surfaces are formed on the tubular section of the carrier element, which correspond to correspondingly shaped guide surfaces of the webs.
  • one or more such inclined surfaces can be formed on the tubular section, which serve for additional support of the webs in each positioning of the webs of the winding body.
  • This measure creates a particularly stable winding body, yet the interior of the winding body is free of further components, so that, for example, air or warm air can flow freely into the winding body.
  • the center! has three-dimensional guide curves which spiral in a plane perpendicular to the central longitudinal axis and increase helically with respect to the longitudinal central axis in the axial direction, a particularly advantageous embodiment of the guide curves of the actuating means is specified.
  • the actuating means has a frustoconical recess on the guide curve side, which is rotatably supported flatly on webs of corresponding incline on the carrier element, indicates a particularly advantageous mounting of the actuating means on the carrier element.
  • pegs at one end of the webs has proven to be extremely advantageous and already suitable for the known winding bodies, the pegs each engaging in a guide curve of the actuating means, so that the webs as a result of the actuation of the actuating means in both radial and axial directions Direction with respect to the longitudinal central axis are positively guided. Due to the mobility of the webs in the axial direction, they can be supported or secured on inclined planes or similar means for any diameter of the winding body with regard to radial, external stress.
  • each web consists of two longitudinal strips, which are connected to one another by transverse webs, advantageously ensures that the webs form a closed jacket of approximately circular cylindrical shape for each diameter of the winding body. Through these openings provided between the crosspieces, warm air entering the winding body can also exit from the latter.
  • the support element or a tubular section of the same is advantageously provided with peripheral openings which cooperate with openings formed between the transverse webs.
  • the fact that the transverse webs have bristle-shaped extensions means that the winding body can be used as a brush or warm air brush with variable diameter guaranteed.
  • the measure of providing a longitudinal edge of the web with a groove-shaped recess, in which at least portions of a further longitudinal ledge of an adjacent web engage in a form-fitting manner in each radial positioning of the webs, has proven to be particularly advantageous.
  • this increases the stability of the entire cradle body, since each web is supported on or in or on an adjacent web, and on the other hand prevents air or warm air introduced into the winding body between the individual webs by any gaps can kick.
  • the hot air can only flow out through the openings provided between the transverse webs of the individual webs, so that the air throughput through the winding body to which hot air is applied remains essentially constant irrespective of the respectively set diameter.

  • the individual webs 13 are driven in the radial and axial directions and move on a path which forms an angle of approximately 45 ° with respect to the central longitudinal axis 112.
  • the angle of 45 "can of course also be varied in a range between 10 and 80 ° according to the individual requirements.
  • the guide curves 24 act radially inwards on the pins 25
  • the force acting on the central longitudinal axis 112 is such that the webs 13 with the corresponding guide surfaces 95, 96 and 97 slide angularly inward and thus also follow the bottom surface 56 of the guide curves 24.
  • the webs 13 are supported in the central section of the carrier element 80 or its tubular section 14 can be seen in particular from Fig. 12.
  • Beneath guide surfaces 96 which are attached to each web 13 in this section and extend at an angle to the central longitudinal axis 112, an inclined surface 99 is formed on the tubular section 14, on which the web 13 changes when the diameter of the winding body changes how to slide down or slide up on an inclined plane
  • This inclined plane provides for each diameter of the winding body to support the webs 13 in the central region with regard to forces acting on the webs 13 from the outside for each set diameter of the winding body.
  • the carrier element 80 At the base of the winding body, as can be seen in particular from FIGS.
  • each chamber 90 is formed by two side walls 44 formed on the carrier element 80.
  • the Crosspieces 13 have end sections which are provided with guide surfaces 97 which are guided in the chambers 90.
  • the ends of the webs 13 have noses 86 (see FIG. 11) which protrude at an angle in the region of the guide surface 97 and are gripped by a section 88 on the tubular region 49.
  • a channel 116 is formed between the bottom 94 of the carrier element 80 and the section 88 of the tube region 49, in which the nose 86 of the webs 13 is guided in a form-fitting manner on an approximately 45 "inclined path.
  • FIG. 12 is secured by small angled pins 58 of the tube area 49 on the support element 80 by the pins 58 interacting with grooves 59.
  • the individual webs 13 have the profiling shown in FIGS. 12 and 14.
  • a first longitudinal bar 102 is connected to a second longitudinal bar 106 via transverse webs 118, which can optionally be provided with bristles 16. Openings are provided in the web 13 between the transverse webs 118, which correspond to corresponding openings 15 in the tubular section 14, so that, for example, warm air can emerge from the winding body.
  • the longitudinal bar 106 has an approximately arrow-shaped shape, the arrowhead being connected to the transverse webs 118.
  • the longitudinal bar 106 is provided with slots 108, so that the edge region takes on an approximately comb-like shape.
  • the longitudinal bar 106 is guided in a form-fitting manner in a recess 104 in the longitudinal bar 102 of a web 13 which is directly adjacent and is designed as a longitudinal groove.
  • the longitudinal bar 106 plunges deeply into the longitudinal groove 104 of the longitudinal bar 102 when the smallest diameter of the winding body is set and partially projects into the openings between the transverse webs 118.
  • the slots 108 are now Arranged on the longitudinal bar 106 such that they essentially correspond to the openings between the transverse webs 118 and thus there is no noticeable increase in the flow resistance for small diameters of the winding body.
  • the longitudinal bar 106 slides out of the recess 104 of the longitudinal bar 102 of an adjacent web 13 for the most part. Irrespective of the set diameter, there is therefore a form fit between adjacent webs in each positioning of the webs 13, so that this exemplary embodiment of the winding former according to the invention also has a high stability against radial stresses.
  • the webs 13 are guided at least on both ends on inclined planes, which is made possible by the axially displaceability of the webs in connection with the three-dimensional guide curve 24 of the adjusting means 23.
  • one or more inclined planes can be provided in the central region of the webs on the tubular section 14, as required.
  • this winding body also has a circumferential surface which is essentially circular for all winding diameters. Only for larger diameters of the winding body are formed between adjacent webs 13 longitudinal groove-like depressions with a depth that corresponds to about a third of the thickness of the web 102.
  • this winding body is characterized by its simple manufacture and is also well suited for use as a hot air brush. According to FIG. 12, the bristle axes 122 of the optionally provided bristles 16 have a slight deviation from the exact radial alignment, but this deviation of a few degrees is negligible for the practical use of such a winding body.
  • both embodiments of the winding body according to the invention have their own advantages, but in the event that the stability aspect of the winding body is in the foreground, the second embodiment is to be preferred, since it is possible here without further, as many support surfaces as required in the middle region to provide the webs 13.

Abstract

Il est décrit un bigoudi destiné à un appareil pour le soin des cheveux, ledit bigoudi présentant un élément porteur (80) sur lequel sont prévus des moyens pour le guidage de plusieurs arêtes (13). Les arêtes (13) peuvent être amenées par des moyens de réglage dans différentes positions, afin de former un bigoudi d'un diamètre extérieur variable. Chaque arête (13) présente sur son étendue longitudinale un évidement (39) avec lequel sont assemblées par forme, dans chaque positionnement des arêtes, les sections d'une arête disposée dans le voisinage. Une autre mesure pour augmenter la stabilité du bigoudi consiste à disposer les arêtes (13) mobiles axialement sur l'élément porteur (80).
