Definitions
- the invention relates to a hair roller for producing permanent hair styling.
- FR-PS 24 586 a hair roller with comb teeth is described, which is designed wavy. In this, individual waves can be deflected differently. Due to different deflections of individual vibrations, a relatively natural hair curl is only achieved to a small extent, since different wavy areas are too far apart. A collapse and mixing of corresponding areas of a strand of hair no longer occurs. In addition, the loops mentioned above are formed in the winder of FR-PS 24 586.
- DE-U 89 11 970 discloses a hair curler of elliptical cross section according to the preamble of claim 1, the cross section of which is enlarged towards the ends of the curler.
- coiled hair curlers are known according to the preamble of claim 3. In cross-section, these hair curlers have an angular or rounded shape.
- the invention has for its object to provide a hair curler that enables loop-free flat winding, and with which a hair curl can be achieved that largely corresponds to a natural hair curl.
- the hair roller is curved in its longitudinal direction at least along a section such that its surface lines run axially asymmetrically to the center line in a cutting plane running through its center line.

- the hair roller is wound in its longitudinal direction at least along a section.
- the winding based on the total length of the winder, is between half a turn and three turns.
- a cutting plane running radially through the central axis of the hair roller has an elliptical shape with the same circumference at all times. The larger ellipse diameter is at most four times the smaller one.
- the hair curlers according to the invention have the advantage that they can be used to implement a hair curl that largely corresponds to that of naturally wavy hair.
- the naturally occurring uneven curl is reproduced either by the elliptical cross-section which changes periodically or non-periodically in the longitudinal direction of the hair roller (claim 1) or by a winding of the hair roller with a relatively sharp rise (claim 3).
- all elliptical cross-sectional areas have the same circumference, all hair of a strand can be wound under the same tension, so that no loop formation occurs on part of the strand.
- the most common winding method, the flat winding is used in the hair roller according to the invention. A user thus does not have to deal with a new type of winding technology that is unusual for him.
- the axis symmetry of a second cutting plane rotated by 90 ° to the first cutting plane about the central axis facilitates the manufacture of the hair roller according to claim 1 insofar as, for example, the molds for plastic molding can be manufactured more easily.
- the intersection points of the ellipse diameters then lie on the central axis of the hair roller.
- the hair curlers according to the invention can also be used in a manner known per se for a particularly uniform tangential winding of a strand of hair, with superimposed winding levels hardly experience any curvature in the direction of the longitudinal axis of the hair roller.

- a system of different sizes with regard to the length and / or the diameter and / or the geometry of the curved section has the advantage that special hair curlers are available for specific hair lengths or applications.
- a relatively simple recognition and assignment of these hair curlers is achieved if uniform curler sizes are provided with a uniform color.
- the curler according to claim 1 is two-colored, and the color separation takes place via an essentially wavy, longitudinal dividing line, then the optical recognition of the curved hair curler by the user is improved.
- a hair roller 1 according to claim 1 as a first embodiment is curved in its longitudinal direction ( Figure 1).
- the generatrices 2a in the first sectional plane running through the central axis 3 of the hair roller 1, which corresponds to the paper plane in FIG. 1, do not run axisymmetrically to the central axis 3, but rather approximately equidistant from one another.
- the hair roller 1 has an elliptical cross section.
- a series of radial cuts (AA to GG) at equal intervals is shown in Figure 5.
- the curved section 4 is followed by an area 9, the circumference of which continuously increases in the longitudinal direction pointing away from the curved section 4 (FIG. 3, FIG. 4).
- the following dimensioning has proven to be a practical example of a winder size: length (without devices 6): approx. 80 mm, ellipse diameter and distances as indicated above.
- the hair roller 10 is wound in its longitudinal direction in a section 11 ( Figure 6).
- section 11 the helix makes approximately one complete revolution. Based on the total length of the winder, there are approx. 1.5 turns purely mathematically. A narrower turn than that specified according to the invention can cause individual parts of a strand of hair to slide away in the longitudinal direction of the hair roller 10. The wound strand of hair is thus split. A steeper turn than that of the invention given, however, no longer leads to the desired hair treatment result, which should be a curl that comes very close to the natural hair curl.
- the hair roller In a radial section through the central axis 12 of the hair roller 10 in the coiled section 11, the hair roller has an elliptical cross section.
- FIG. 7 A series of equidistant radial cuts (AA to EE) is shown in FIG. 7.
- the representations show ellipses of the same diameter h 1 and h 2.
- the ellipse of section BB is rotated 45 ° around its center of gravity.
- the ellipse was successively rotated by 180 °.
- the shape of the ellipse is defined according to the invention such that it has a constant circumference, and that the larger ellipse diameter h 1 is at most four times the size of the smaller ellipse diameter h 2. From a factor greater than four, the ellipse is extended too much in one direction and the other direction perpendicular to it is insufficiently pronounced. The consequence of this is too much hair styling at the smallest radius of curvature of the ellipse and too weak hair styling at the largest radius of curvature.
- the hair curler 10 (FIG. 6) is configured analogously to the hair curler 1 (FIGS. 1 and 3) at its ends with devices 13a, 13b for receiving a rubber band, cylindrical areas 14, and conical areas 15.

Description
Die Erfindung betrifft einen Haarwickler zur Erzeugung einer permanenten Haarformung.The invention relates to a hair roller for producing permanent hair styling.
Aus der EP-OS 0 056 605 ist ein gewellter Haarwickler bekannt, mit dem unter Verwendung einer besonderen, aufwendigen Wickelmethode eine relativ natürliche Haarumformung erzielt wird. Nachteilig ist bei diesem Haarwickler, daß er sich für die in der Praxis übliche Wickeltechnik, die sogenannte Flachwicklung, wenig eignet.
Bei dieser Technik wird eine Haarsträhne tangential aufgewickelt. Würde man den Wickler der EP-OS 0 056 605 derart gebrauchen, so könnte man eine Haarsträhne nur teilweise ausreichend fest um den Wickler legen. Eine Vielzahl der Haare einer Strähnengesamtheit würde dagegen unter Schlaufenbildung nur lose am Wickler hängen. Die für eine Dauerwellung vorteilhafte genaue Umformung wäre dabei nicht erzielbar.From EP-OS 0 056 605 a wavy hair curler is known, with which a relatively natural hair styling is achieved using a special, complex winding method. The disadvantage of this hair curler is that it is not very suitable for the winding technique used in practice, the so-called flat winding.
With this technique, a strand of hair is wound tangentially. If the winder of EP-OS 0 056 605 were to be used in this way, then a strand of hair could only be placed around the winder sufficiently firmly. On the other hand, a large number of the hairs of a strand of strands would only hang loosely on the curler while forming loops. The precise shaping advantageous for permanent corrugation would not be achievable.
In der FR-PS 24 586 ist ein Haarwickler mit Kammzinken beschrieben, der wellenförmig ausgestaltet ist. Bei diesem können einzelne Wellen unterschiedlich ausgelenkt sein. Durch unterschiedliche Auslenkung einzelner Schwingungen wird aber nur in einem geringen Maß eine relativ natürliche Haarwellung erreicht, da unterschiedliche Wellenbereiche zu weit voneinander entfernt sind. Ein Ineinanderfallen und Vermischen entsprechender Bereiche einer Haarsträhne kommt dabei nicht mehr vor. Zudem bilden sich bei dem Wickler der FR-PS 24 586 die oben erwähnten Schlaufen.In FR-PS 24 586 a hair roller with comb teeth is described, which is designed wavy. In this, individual waves can be deflected differently. Due to different deflections of individual vibrations, a relatively natural hair curl is only achieved to a small extent, since different wavy areas are too far apart. A collapse and mixing of corresponding areas of a strand of hair no longer occurs. In addition, the loops mentioned above are formed in the winder of FR-PS 24 586.
Die DE-U 89 11 970 offenbart einen Haarwickler elliptischen Querschnitts gemäß dem Oberbegriff des Anspruchs 1, dessen Querschnitt zu den Wicklerenden hin vergrößert ist.DE-U 89 11 970 discloses a hair curler of elliptical cross section according to the preamble of claim 1, the cross section of which is enlarged towards the ends of the curler.
Aus der FR-OS 23 85 354 sind gewendelte Haarwickler gemäß dem Oberbegriff des Anspruchs 3 bekannt. Im Querschnitt weisen diese Haarwickler eine eckige oder eine abgerundete Form auf.From FR-OS 23 85 354 coiled hair curlers are known according to the preamble of
Der Erfindung liegt die Aufgabe zugrunde, einen Haarwickler zu schaffen, der eine schlaufenfreie Flachwicklung ermöglicht, und mit dem eine Haarwellung erzielt werden kann, die einer natürlichen Haarwellung weitgehend entspricht.The invention has for its object to provide a hair curler that enables loop-free flat winding, and with which a hair curl can be achieved that largely corresponds to a natural hair curl.
Gelöst ist die Aufgabe gemäß den kennzeichnenden Teilen der Ansprüche 1 oder 3.The object is achieved according to the characterizing parts of
Nach Anspruch 1 ist der Haarwickler in seiner Längsrichtung mindestens entlang eines Abschnittes derart geschwungen, daß seine Mantellinien in einer durch seine Mittellinie verlaufenden Schnittebene achsenasymmetrisch zur Mittellinie verlaufen. Im Radialschnitt durch seine Mittelachse weist der Haarwickler in einem Abschnitt mit den vorgenannten Merkmalen einen elliptischen Querschnitt auf. In Längsrichtung verändern sich die Ellipsendurchmesser. Der Ellipsenumfang bleibt jedoch konstant.According to claim 1, the hair roller is curved in its longitudinal direction at least along a section such that its surface lines run axially asymmetrically to the center line in a cutting plane running through its center line. In a radial section through its central axis, the hair curler has an elliptical cross section in a section with the aforementioned features. The ellipse diameters change in the longitudinal direction. However, the ellipse circumference remains constant.
Gemäß Anspruch 3 ist der Haarwickler in seiner Längsrichtung mindestens entlang eines Abschnittes gewendelt. Die Wendelung macht, bezogen auf die gesamte Wicklerlänge zwischen einer halben Umdrehung und drei Umdrehungen aus. Eine radial durch die Mittelachse des Haarwicklers verlaufende Schnittebene hat eine Ellipsenform mit stets gleichem Umfang. Der größere Ellipsendurchmesser ist höchstens viermal so groß wie der kleinere.According to
Die erfindungsgemäßen Haarwickler haben den Vorteil, daß mit ihnen eine Haarwellung realisiert werden kann, die der von naturgewelltem Haar weitgehend entspricht. Die natürlich vorkommende ungleichmäßige Wellung wird entweder durch den in Längsrichtung des Haarwicklers periodisch oder unperiodisch sich ändernden Ellipsenquerschnitt (Anspruch 1) oder durch eine Wendelung des Haarwicklers mit relativ starkem Anstieg (Anspruch 3) reproduziert. Dadurch, daß alle elliptischen Querschnittsflächen den gleichen Umfang haben, können alle Haare einer Strähne unter gleicher Spannung aufgewickelt werden, so daß keine Schlaufenbildung an einem Teil der Haarsträhne auftritt. Die geläufigste Wickelmethode, die Flachwicklung, findet beim erfindungsgemäßen Haarwickler Anwendung. Ein Benutzer braucht sich somit nicht mit einer für ihn ungewohnten neuartigen Wickeltechnik zu befassen.The hair curlers according to the invention have the advantage that they can be used to implement a hair curl that largely corresponds to that of naturally wavy hair. The naturally occurring uneven curl is reproduced either by the elliptical cross-section which changes periodically or non-periodically in the longitudinal direction of the hair roller (claim 1) or by a winding of the hair roller with a relatively sharp rise (claim 3). As a result of that all elliptical cross-sectional areas have the same circumference, all hair of a strand can be wound under the same tension, so that no loop formation occurs on part of the strand. The most common winding method, the flat winding, is used in the hair roller according to the invention. A user thus does not have to deal with a new type of winding technology that is unusual for him.
Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Haarwicklers sind in den Ansprüchen 2 und 4 bis 10 beschrieben.Further advantageous embodiments of the hair curler according to the invention are described in
Die Achsensymmetrie einer zweiten, um 90° zur ersten Schnittebene um die Mittelachse verdrehten Schnittebene (Anspruch 2) erleichtert die Fertigung des Haarwicklers gemäß Anspruch 1 insofern, als zum Beispiel die Formen für eine Kunststofformung einfacher hergestellt werden können. Die Schnittpunkte der Ellipsendurchmesser liegen dann auf der Mittelachse des Haarwicklers.The axis symmetry of a second cutting plane rotated by 90 ° to the first cutting plane about the central axis (claim 2) facilitates the manufacture of the hair roller according to claim 1 insofar as, for example, the molds for plastic molding can be manufactured more easily. The intersection points of the ellipse diameters then lie on the central axis of the hair roller.
Schließt sich an den Abschnitt ein Bereich an, dessen Umfang in die vom Abschnitt weg weisende Längsrichtung stetig zunimmt (Anspruch 4), so können die erfindungsgemäßen Haarwickler auch in an sich bekannter Weise zu einer besonders gleichmäßigen tangentialen Aufwicklung einer Haarsträhne verwendet werden, wobei aufeinanderliegende Wickelebenen kaum eine Krümmung in der Richtung zur Längsachse des Haarwicklers erfahren.If the section is adjoined by a region whose circumference increases continuously in the longitudinal direction pointing away from the section (claim 4), the hair curlers according to the invention can also be used in a manner known per se for a particularly uniform tangential winding of a strand of hair, with superimposed winding levels hardly experience any curvature in the direction of the longitudinal axis of the hair roller.
Sind gemäß Anspruch 5 an den Enden der Haarwickler bezüglich der Mittelachse des Haarwicklers rotationssymmetrisch orientierte zylindrische Bereiche vorgesehen, so wird dadurch die Handhabung des Haarwicklers verbessert.If, according to
Ein zur besseren Fixierung der Haarwickler geeignetes Gummiband kann in einfacher Weise entlang der Haarwickler gespannt werden, wenn gemäß Anspruch 6 an den Enden der Haarwickler Einrichtungen zur Aufnahme dieses Gummibandes vorgesehen sind.A rubber band suitable for better fixation of the hair curlers can be stretched in a simple manner along the hair curlers if, according to claim 6, devices for receiving this rubber band are provided at the ends of the hair curlers.
Ist ein Haarwickler hohl und sind in seiner Mantelfläche Durchbrüche vorgesehen (Anspruch 7), so wird außer einer deutlichen Gewichtsreduzierung noch erreicht, daß am Wickler kein Stau der Behandlungsflüssigkeit vorkommen kann, da überschüssige Flüssigkeit in den Wickler fließen kann.If a hair roller is hollow and openings are provided in its outer surface (claim 7), it is achieved in addition to a significant reduction in weight that no jam of the treatment liquid can occur on the roller, since excess liquid can flow into the roller.
Die Griffigkeit eines Haarwicklers wird erhöht und sein Schlupfvermögen verringert, wenn gemäß Anspruch 8 die äußere Mantelfläche des Haarwicklers rauh ist.The grip of a hair roller is increased and its slippage capacity is reduced if, according to claim 8, the outer surface of the hair roller is rough.
Ein System von unterschiedlichen Größen hinsichtlich der Länge und/oder des Durchmessers und/oder der Geometrie des geschwungenen Abschnittes (Anspruch 9) hat den Vorteil, daß für bestimmte Haarlängen oder Anwendungsfälle jeweils spezielle Haarwickler zur Verfügung stehen. Ein relativ einfaches Erkennen und Zuordnen dieser Haarwickler wird erreicht, wenn gemäß Anspruch 10 einheitliche Wicklergrößen mit einer einheitlichen Farbgebung versehen sind.A system of different sizes with regard to the length and / or the diameter and / or the geometry of the curved section (claim 9) has the advantage that special hair curlers are available for specific hair lengths or applications. A relatively simple recognition and assignment of these hair curlers is achieved if uniform curler sizes are provided with a uniform color.
Ist gemäß Anspruch 11 der Wickler nach Anspruch 1 zweifarbig, und erfolgt die Farbentrennung über eine im wesentlichen wellenförmige, in Längsrichtung verlaufende Trennlinie, dann wird die optische Erkennung des geschwungenen Haarwicklers seitens des Benutzers verbessert.If, according to

Ein Haarwickler 1 gemäß Anspruch 1 als ein erstes Ausführungsbeispiel ist in seiner Längsrichtung geschwungen (Figur 1). Die Mantellinien 2a in der durch die Mittelachse 3 des Haarwicklers 1 verlaufenden ersten Schnittebene, welche der Papierebene in figur 1 entspricht, verlaufen nicht achsensymmetrisch zur Mittelachse 3, sondern in etwa äquidistant zueinander. Im Radialschnitt durch die Mittelachse 3 des Haarwicklers 1 im geschwungenen Abschnitt 4 weist der Haarwickler 1 einen elliptischen Querschnitt auf. Eine Serie von Radialschnitten (A-A bis G-G) in gleichen Abständen ist in Figur 5 dargestellt. Zur besseren Verdeutlichung, wie sich die Ellipsendurchmesser in Längsrichtung des Haarwicklers 1 verändern, und daß der Umfang der Schnittabbildung stets konstant ist, sind nachfolgend die Ellipsendurchmesser benannt: a₁ = 9,55; a₂ = 9,45; b₁= 9,63; b₂ = 9,37; c₁ = 9,77; c₂ = 9,23; d₁ = 9,93; d₂ = 9,07; e₁ = 10,04; e₂ = 8,96; f₁ = 10,07; f₂ = 8,93; g₁ = 9,99; g₂ = 9,01 [mm].
Im geschwungenen Abschnitt 4 des Haarwicklers 1 müssen sich die Ellipsendurchmesser nicht periodisch ändern. Eine unperiodische, unregelmäßige Veränderung über einen Teil des geschwungenen Abschnitts 4 ist genauso akzeptabel wie eine über den gesamten Bereich des geschwungenen Abschnitts 4. In einer zur ersten Schnittebene um 90° um die Mittelachse 3 verdrehten zweiten Schnittebene verlaufen die Mantellinien 2b achsensymmetrisch zur Mittelachse (Figur 2). An den geschwungenen Abschnitt 4 schließen sich beidseitig bezüglich der Mittelachse 3 des Haarwicklers 1 rotationssymmetrisch orientierte zylindrische Bereiche 5 an (Figur 1, Figur 2). An den Enden des Haarwicklers 1 sind in an sich bekannter Art Einrichtungen 6 zur Aufnahme eines nicht dargestellten Gummibandes vorgesehen. Diese Einrichtungen 6 bestehen aus einer Ringnut 7 und einem Nocken 8.A hair roller 1 according to claim 1 as a first embodiment is curved in its longitudinal direction (Figure 1). The
In the curved section 4 of the hair roller 1 must be do not change the ellipse diameter periodically. An unperiodic, irregular change over part of the curved section 4 is just as acceptable as one over the entire area of the curved section 4. In a second sectional plane rotated by 90 ° around the
In einem weiteren Ausführungsbeispiel des Haarwicklers 1 gemäß Anspruch 1 schließt sich an den geschwungenen Abschnitt 4 je ein Bereich 9 an, dessen Umfang in die vom geschwungenen Abschnitt 4 weg weisende Längsrichtung stetig zunimmt (Figur 3, Figur 4).
Als praktisches Beispiel einer Wicklergröße hat sich folgende Dimensionierung bewährt: Länge (ohne Einrichtungen 6): ca. 80 mm, Ellipsendurchmesser und Abstände wie vorstehend angegeben.In a further exemplary embodiment of the hair curler 1 according to claim 1, the curved section 4 is followed by an
The following dimensioning has proven to be a practical example of a winder size: length (without devices 6): approx. 80 mm, ellipse diameter and distances as indicated above.
In einem Ausführungsbeispiel des Haarwicklers gemäß Anspruch 3 ist der Haarwickler 10 in seiner Längsrichtung in einem Abschnitt 11 gewendelt (Figur 6). Die Wendelung macht im Abschnitt 11 ca. eine ganze Umdrehung aus. Bezogen auf die gesamte Wicklerlänge ergeben sich rein rechnerisch ca. 1,5 Windungen. Eine engere Wendelung als die erfindungsgemäß vorgegebene kann zu einem Wegrutschen einzelner Teile einer Haarsträhne in Längsrichtung des Haarwicklers 10 führen. Die aufgewickelte Haarsträhne wird somit aufgespalten. Eine steilere Wendelung als die erfindungsgemäß gegebene führt dagegen nicht mehr zu dem gewünschten Haarbehandlungsergebnis, welches eine der natürlichen Haarwellung sehr nahe kommende Wellung sein soll. Im Radialschnitt durch die Mittelachse 12 des Haarwicklers 10 im gewendelten Abschnitt 11 weist der Haarwickler einen elliptischen Querschnitt auf. Eine Serie von äquidistant vorgenommenen Radialschnitten (A-A bis E-E) ist in der Figur 7 dargestellt. Die Darstellungen zeigen Ellipsen gleicher Durchmesser h₁ und h₂. Gegenüber dem Schnitt A-A ist die Ellipse des Schnittes B-B um 45° um ihren Schwerpunkt gedreht. Bis zum Schnitt E-E ist sukzessive eine Drehung der Ellipse um 180° erfolgt.
Die Form der Ellipse ist erfindungsgemäß derart festgelegt, daß sie einen konstanten Umfang hat, und daß der größere Ellipsendurchmesser h₁ höchstens viermal so groß wie der kleinere Ellipsendurchmesser h₂ ist.
Ab einem Faktor größer als vier wird die Ellipse zu stark in die eine Richtung erstreckt und die andere, senkrecht dazu stehende Richtung ist zu wenig ausgeprägt. Die Folge davon ist eine zu starke Haarumformung am kleinsten Krümmungsradius der Ellipse und eine zu schwache Haarumformung am größten Krümmungsradius.In one embodiment of the hair roller according to
The shape of the ellipse is defined according to the invention such that it has a constant circumference, and that the larger ellipse diameter h 1 is at most four times the size of the smaller
From a factor greater than four, the ellipse is extended too much in one direction and the other direction perpendicular to it is insufficiently pronounced. The consequence of this is too much hair styling at the smallest radius of curvature of the ellipse and too weak hair styling at the largest radius of curvature.
Der Haarwickler 10 (Figur 6) ist analog dem Haarwickler 1 (Figuren 1 und 3) an seinen Enden mit Einrichtungen 13a, 13b zur Aufnahme eines Gummibandes, zylindrischen Bereichen 14, und konischen Bereichen 15 ausgestaltet.
Selbstverständlich können auch alle anderen, an Haarwicklern bekannten Befestigungseinrichtungen, wie z. B. durch die Wicklerenden steckbare Befestigungsstifte oder Klemmen für eine Wicklerbefestigung anstatt der beschriebenen Befestigungseinrichtungen zum Anbringen der erfindungsgemäßen Haarwickler 1,10 genommen werden.The hair curler 10 (FIG. 6) is configured analogously to the hair curler 1 (FIGS. 1 and 3) at its ends with
Of course, all other fastening devices known on hair rollers, such as. B. by the winder ends plug-in fastening pins or clamps for a winder fastening instead of the described fastening devices for attaching the hair winder 1.10 according to the invention.
