Description

Die Erfindung betrifft einen Haarwickler zum Aufrollen von Haaren. Solche Haarwickler bestehen üblicherweise aus einem Wickelkern, der Öffnungen zum Durchtritt der im Haar nach einer Haarwasche noch vorhandenen Feuchtigkeit aufweist, und einem darauf befestigten Klettband. Ein derartiger Wickler ist aus der DE-A-1 457 375 bekannt. Die Rückseite des erfindungsgemäßen Klettbandes weist aus dem gleichen Grund Öffnungen auf, die von gitterartig angeordneten Streben gebildet werden.The invention relates to a hair roller for rolling up hair. Such hair curlers usually consist of a winding core, which has openings for the passage of the moisture still present in the hair after washing the hair, and a Velcro fastener fastened thereon. Such a winder is known from DE-A-1 457 375. For the same reason, the back of the Velcro tape according to the invention has openings which are formed by struts arranged in a grid.

In der Frisurentechnik sind zahlreiche Formen von Haarwicklern bekannt, auf denen das vornehmlich weibliche Haar zur Erzielung von Lockenbildung aufgerollt wird. Solche Haarwickler sind als Lockenwickler wohlbekannt.In hairstyle technology, numerous forms of hair curlers are known, on which the predominantly female hair is rolled up in order to achieve curls. Such hair curlers are well known as curlers.

Die Technik des Haaraufrollens ist nicht umproblematisch, da das Haar leicht auf einer glatten Wickler-Rolle rutscht. Außderdem muß das Haar für eine zeitlang straff auf dem Haarwickler fixiert werden, um die Lockenbildung zu gewährleisten.The technique of rolling up the hair is not without problems because the hair easily slides on a smooth roller. In addition, the hair must be fixed tight on the hair roller for a while to ensure the formation of curls.

Um die Aufrolltechnik zu vereinfachen, wurden zahlreiche Haarwicklerformen entwickelt, die alle den Zweck verfolgen, die Anfangsfixierung auf dem Haarwickler zu erleichtern.In order to simplify the roll-up technique, numerous forms of hair curlers have been developed, all of which have the purpose of facilitating the initial fixing on the hair curler.

So werden z.B. Borstenbündel in Form von Rundbürsten in den Kern des Haarwicklers geschoben, deren Borsten dann die als offene Netzstruktur ausgebildete Wandung des Haarwicklers durchdringen und eine bürstenähnliche Oberfläche des Haarwicklers bilden. In den Borsten läßt sich das Haar besser am Beginn des Rollens fixieren, so daß das stramme Aufwickeln erleichtert ist. Demselben Zweck dienen Spritzguss-Plastikwickler, deren Oberfläche Plastik-Borsten aufweist.For example, Bristle bundles in the form of round brushes are pushed into the core of the hair curler, the bristles of which then penetrate the wall of the hair curler formed as an open network structure and form a brush-like surface of the hair curler. It is easier to fix the hair in the bristles at the beginning of the rolling process, so that tight winding is easier. Injection-molded plastic winders, the surface of which has plastic bristles, serve the same purpose.

Allen vorbeschriebenen Haarwicklern gemeinsam ist die Notwendigkeit, nach Abschluß des Wickelns die Haarrolle mit Hilfe von Spangen, Klammern oder Nadeln zu befestigen. Solche Handhabung erfordert Geschick und Training, was selbstverständlich hinreichend professionell in Friseursalons geboten wird.Common to all of the above-described hair curlers is the need to fasten the hair roller with the help of clips, clips or needles after the winding is complete. Such handling requires skill and training, which of course is offered sufficiently professionally in hairdressing salons.

Immer mehr Frauen gehen jedoch dazu über, sich die Locken selbst zu wickeln und den zeitraubenden und kostspieligen Aufenthalt beim Friseur zu ersparen. Da das Talent der Heimbehandlerin naturgemäß dem des professionellen Friseurs unterlegen ist und außerdem zumeist keine zweite Person zur Verfügung steht, sind die technischen Anforderungen an einen Haarwickler für den Heimbedarf weitaus höher als für solche Haarwickler, die professionell genuzt werden.However, more and more women are turning to curling themselves and sparing the time-consuming and expensive stay at the hairdresser. Since the talent of the home therapist is naturally inferior to that of the professional hairdresser and, moreover, there is usually no second person available, the technical requirements for a hair curler for home use are much higher than for those hair curlers that are used professionally.

Diesen Zweck erfüllen selbsthaftende Haarwickler auf Basis von Klettband.Self-adhesive hair curlers based on Velcro serve this purpose.

Klettband ist weithin bekannt als Verschluß-System im Bekleidungsbereich. Bei dieser Verwendung finden zweierlei Bänder Anwendung, nämlich eines mit zahlreichen Haken, da andere mit ebenso vielen Ösen an der Oberfläche. Bringt man beide Bänder unter leichtem Druck zusammen, verkletten diese sofort ineinander und bilden einen äußerst festen Verschluß. Als Material für diese im größtem Ausmaß eingesetzten Klettbänder wird meist Kunststoff, insbesondere auf der Basis von Polyamiden wie Nylon verwendet.Velcro is widely known as a fastener system in the clothing sector. Two types of tapes are used in this application, one with numerous hooks and the other with as many eyelets on the surface. If you bring both tapes together under slight pressure, they immediately cling together and form an extremely tight closure. Plastic is mostly used as the material for these Velcro tapes, which are used to the greatest extent, in particular based on polyamides such as nylon.

Beim selbsthaftenden Klettband-Haarwickler ist nur eine Lage Klettband erforderlich. Dabei wird die Bandausführung so modifiziert, daß die Haken länger sind, um eine ausreichende Haftwirkung auf das Rollenbündel der Haare auszuüben und um auch bei langem Haar und dicken Haarbündeln noch ausreichende Fixierwirkung zu haben. Außerdem verbindet die Hakenreihen ein offenes aus Streben aufgebautes Nylongitter, durch das Fönluft des Haartrockners leicht hindurchgeht.With the self-adhesive Velcro hair roller, only one layer of Velcro is required. The tape design is modified so that the hooks are longer in order to exert a sufficient adhesive effect on the roller bundle of the hair and to still have sufficient fixing action even with long hair and thick hair bundles. In addition, the rows of hooks are connected by an open nylon grid made of struts, through which hair dryer air easily passes.

Der Haarwickler selbst ist durch Öffnungen in seinem Außenmantel gut belüftet.The hair curler itself is well ventilated through openings in its outer jacket.

Das selbsthaftende Klettband wird mit dem Wickelkern, der meist ebenfalls aus Plasitk besteht, fest verbunden.The self-adhesive Velcro tape is firmly connected to the winding core, which usually also consists of plastic.

Diese Haarwickler sind im Markt der Heimbehandlung, aber auch beim Frisueur außerordentlich erfolgreich und bilden inzwischen ein erhebliches Martpotential.These hair curlers are extremely successful in the home treatment market, but also in hairdressing, and meanwhile have a considerable market potential.

Sie erleichtern das Anfixieren der Haare zu Beginn des Aufrollens, das stramme Aufwickeln und sie benötigen keine Nadeln, Klammern oder Spangen. Sie halten die Haarrolle nach Abschluß des Wickelns ohne jegliche zusätzliche Maßnahme fest fixiert. Wichtig ist dabei, daß das Klettband stramm auf dem Wickelkern aufsitz, keine Falten bildet und nicht auf dem Wickelkern rutscht.They make it easier to fix the hair at the beginning of the curling, tight winding and you do not need any needles, clips or clips. You hold that Hair roller firmly fixed after completion of the winding without any additional measures. It is important that the Velcro tape sits tight on the winding core, does not form folds and does not slide on the winding core.

Solche Haarwickler haben jedoch den Nachteil, daß sie außerordentlich aufwendig sind Das liegt einmal an dem hohen Preis für das Klettband, zum anderen an der Produktionstechnik, die noch weitgehend Handarbeit ist.Such hair curlers have the disadvantage, however, that they are extremely complex. This is partly due to the high price for the Velcro, and partly due to the production technology, which is still largely manual.

Als sehr geeignet und auch preiswert hat sich Polypropylen für den Wickelkern erwiesen. Um diesen Wickelkern, der in bis zu 15 verschiedenen Durchmessern angeboten wird, wird das Klettband gewickelt und am Ende mit leichter Überlappung thermisch aufeinander verschweißt. Die Verschweißung von Nylon mit Nylon geht keine Verbindung mit dem darunter liegenden Wicklkern aus Polypropylen ein, so daß das Band lose beweglich auf dem Kern liegt. da das Klettband bei Beginn des Aufwickelns um den Kern ebenfalls keine Fixierung hat, ist es oft sehr lose gewickelt und bildet beim Haaraufwickeln leicht Falten.Polypropylene has proven to be very suitable and inexpensive for the winding core. The Velcro is wrapped around this winding core, which is available in up to 15 different diameters, and thermally welded to one another with a slight overlap at the end. The welding of nylon to nylon is not connected to the underlying polypropylene winding core, so that the tape lies loosely on the core. since the Velcro tape also has no fixation at the beginning of the winding around the core, it is often wound very loosely and easily forms folds when winding up the hair.

Viele Versuche wurden unternommen, um diesen Mängeln abzuhelfen. So wurde die Schweißnaht so tief aufgeführt, daß das darunter liegende Plastikmaterial des Wickelkerns mit verflüssigt wurde Materialfluß in das Nylon-Klettband erfolgte und dieses so eine gewisse mechanische Verfestigung erhielt.Many attempts have been made to remedy these shortcomings. So the weld seam was so deep that the underlying plastic material of the winding core was liquefied with the material flow into the nylon Velcro tape and this was given a certain mechanical strengthening.

In zahlreichen Fällen wird dabei das Nylonband dann aber so dünn, daß es leicht bricht. Auch ist eine solche Schweißnaht sehr unansehnlich und hat oftmals über den Rand des Wicklers hervortretende verschmolzene, harte Enden. Nachteilig ist bei diesem Verfahren außerdem, daß nur ein kleines Segment von ca 5° des Umfanges der Haarrolle fest verbunden ist, die restlichen 355° sitzen lose auf dem Wickelkern.In numerous cases, the nylon tape then becomes so thin that it breaks easily. Such a weld seam is also very unsightly and often has fused, hard ends protruding from the edge of the winder. Another disadvantage of this method is that only a small segment of approximately 5 ° of the circumference the hair roller is firmly connected, the remaining 355 ° sit loosely on the winding core.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und einen Haarwickler gemäß dem Gattungsbegriff dieser Anmeldung zu schaffen, der eine einfache Handhabung des Haarwicklers ermöglicht, auch von der Person selbst, die diesen Haarwickler trägt. Er soll trotzdem eine sichere Festlegung der Haare auf dem Haarwickler garantieren, ein straffes Aufwickeln gewährleisten und eine maschinelle Fertigung ermöglichen.The invention has for its object to avoid these disadvantages and to provide a hair roller according to the preamble of this application, which allows easy handling of the hair roller, even by the person who wears this hair roller. Nevertheless, it should guarantee a secure fixing of the hair on the hair roller, ensure a tight winding and enable machine production.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Wickelkern an seinem Außenmantel mindestens einen, zweckmäßig zwei und vorteilhaft sogar vier und mehr Zapfen aufweist, die in die offenen Streben an der Rückseite des Klettbandes eindrückbar sind. Durch den Zapfen am Außenmantel des Wickelkerns wird der Vorteil erzielt, daß dieser Zapfen beim Herumlegen des Klettbandes um den Wicklkern das Klettband unverrückbar und fest am Wicklkern hält und in seiner Lage festliegt und das Anlegen des Haarwicklers erheblich erleichtet ist und mühelos von einer Person im Frisiersalon oder von der Benutzerin bzw. dem Benutzer selbst bei Heimbehandlung verrichtet werden kann. Mit der Fixierung des Klettbandes auf dem Wickelkern ist der weitere Vorteil verbunden, daß die Herstellung des Haarwicklers nunmehr auch mechanisiert werden kann und gegenüber der bisherigen Handarbeit bei der Herstellung jetzt ein fabrikatorischer Ablauf möglich ist.According to the invention the object is achieved in that the winding core has at least one, expediently two and advantageously even four and more pins on its outer jacket, which can be pressed into the open struts on the back of the Velcro tape. The peg on the outer jacket of the winding core has the advantage that this peg holds the Velcro firmly and firmly on the winding core when it is put around the Velcro around the winding core or can be performed by the user himself at home. Fixing the Velcro tape on the winding core has the further advantage that the manufacture of the hair curler can now also be mechanized and, compared to the previous manual work in the manufacture, a manufacturing process is now possible.

Zur Erzielung des angestrebten technischen Effektes reicht bereits ein einziger Zapfen am Außenmantel des Wickelkerns aus. Er ist dann in Achsrichtung gesehen zweckmäßig mittig angeordnet, um eine über die Breite des Haarwicklers gleichmäßige Aufrollung der Haare zu bewirken. Zweckmäßig sind aber mehrer Zapfen möglichst symetrisch über den Umfang des Außenmantels verteilt angeordnet, bevorzugt zwei bis vier, weil dann mit größerer Kraft und strammer das feuchte Haar aufgewickelt werden kann.To achieve the desired technical effect, a single pin on the outer jacket of the winding core is sufficient. It is then expediently arranged centrally in the axial direction, by one across the width of the hair roller to bring about even rolling of the hair. Expediently, however, several pins are arranged as symmetrically as possible over the circumference of the outer jacket, preferably two to four, because then damp hair can be wound up with greater force and tighter.

Bei zwei Zapfen ist es zweckmäßig, diese mit 180° Versetzung auf der Peripherie des Außenmantels anzuordnen und zwar vorteilhaft wiederum mittig in Achsrichtung gesehen. Bevorzugt ist eine versetzte Anordnung sowohl in Achsrichtung als auch auf der Peripherie des Außenmantels. Bei drei und mehr Zapen empfiehlt sich in jedem Fall die versetzte Anordnung der Zapfen sowohl in Achsrichtung als auch auf der Peripherie des Außenmantels, weil so ein gleichmäßiges effektives Aufwickeln des Haares erzielt wird.In the case of two pegs, it is expedient to arrange them with a 180 ° offset on the periphery of the outer casing, and again advantageously in the center in the axial direction. A staggered arrangement is preferred both in the axial direction and on the periphery of the outer casing. If there are three or more pins, the staggered arrangement of the pins in both the axial direction and on the periphery of the outer jacket is recommended in any case, since this achieves a uniform, effective winding of the hair.

In seinem Durchmesser ist der Zapfen zweckmäßig größer als der Abstand benachbarter Streben an der Rückseite des Klettbandes, so daß er im Klemmsitz Klettband und Wickelkern verbindet. Zweckmäßig entspricht der Durchmesser des Zapfens ungefähr dem doppelten Abstand zweier benachbarter Streben.The diameter of the pin is expediently greater than the distance between adjacent struts on the back of the Velcro tape, so that it connects the Velcro tape and winding core in the press fit. The diameter of the pin expediently corresponds to approximately twice the distance between two adjacent struts.

Die einfache Handhabung und Sicherheit des festen Klemmsitzes des Klettbandes auf dem Wickelkern läßt sich noch dadurch verbessern, daß der Zapfen im Bereich seiner Basis eine ganz oder teilweise umlaufende Nut aufweist, in die die offenen Streben des Klettbandes einrasten, wenn das Klettband um den Wickelkern herumgelegt wird, und dieses so unverrückbar auf dem Wickelkern festlegen.The simple handling and security of the firm clamping fit of the Velcro tape on the winding core can be further improved in that the pin has a fully or partially circumferential groove in the region of its base, into which the open struts of the Velcro tape snap when the Velcro tape is placed around the winding core will, and set it so immovably on the winding core.

Die Rückseite des Klettbandes ist bevorzugt ein durch Streben gebildetes Gitter aus Polyamid, insbesondere Nylon, auf dem das Klettband befestigt ist und das sich sowohl durch große Festigkeit als auch Elastizität auszeichnet, so daß der Zapfen mit verhältnismäßig starkem Druck eingedrückt werden kann. Diese Ausführungsform der Rückseite des Klettbandes eignet sich besonders für eine Wickelkern mit einem Zapfen mit umlaufender Nut, weil dabei die Streben des Nylongitters nach dem Eindringen des Zapfens in die Nut einrasten und so einen besonders sicheren Sitz des Klettbandes auf dem Wickelkern bewirken. Diese Sicherheit läßt sich, insbesondere bei einem Zapfen aus thermoplastischem Kunststoff noch dadurch steigern, daß die Spitze des Zapfens, die das Eindringen in das Klettband erleichert, im Nachhinein mittels Wärme pilzkopfartig verformt und dadurch abgestumpft wird.The back of the Velcro is preferably a strut formed from polyamide, especially nylon, on which the Velcro is attached and which is characterized by both great strength and elasticity, so that the pin can be pressed in with relatively strong pressure. This embodiment of the back of the Velcro tape is particularly suitable for a winding core with a spigot with a circumferential groove, because the struts of the nylon grid snap into the groove after the spigot has penetrated and thus ensure a particularly secure fit of the Velcro strip on the winding core. This security can be increased, in particular in the case of a spigot made of thermoplastic material, in that the tip of the spigot, which facilitates penetration into the Velcro strip, is subsequently shaped like a mushroom head by means of heat and is thereby blunted.

Materialmäßig können der Wickelkern und die auf dessen Außenmantel angebrachten Zapfen aus den verschiedensten Stoffen wie Keramik, Blech und Aluminum bestehen. Bevorzugt geeignet ist Kunststoff. Unter den Kunststoffen wird vorzugsweise Polypropylen verwendet, das sich durch niedrigte Gestehungskosten, vor allem aber durch seine leichte Verformbarkeit und Inertheit auszeichnet. Ganz bevorzugt zur Lösung der gestellten Aufgabe ist ein Wickelkern, der aus einem einzigen Stück besteht, vorzugsweise einem Spritzgußteil, das alle funktionswesentlichen Teile aufweist, so daß der Haarwickler lediglich aus zwei Teilen besteht, nämlich dem Wicklkern und dem darauf mit Hilfe des Zapfens befestigten Klettband.In terms of material, the winding core and the pins attached to its outer jacket can be made of a wide variety of materials such as ceramic, sheet metal and aluminum. Plastic is preferred. Polypropylene is preferred among the plastics, which is characterized by low production costs, but above all by its easy deformability and inertness. A winding core, which consists of a single piece, preferably an injection molded part, which has all the functionally essential parts, is very preferred for solving the problem, so that the hair roller consists of only two parts, namely the winding core and the Velcro tape fastened thereon with the aid of the pin .

Dieser einfache Aufbau aus lediglich zwei Teilen und mit der einfachen, aber sicheren Verbindung untereinander gibt die Möglichket der rationellen und maschinellen Fertigung und damit einer großen Ersparnis an Zeitaufwand und für die Fertigung bisher benötigter Arbeitskräfte und damit eine sehr viel wirtschaftlichere Fertigung insgesamt.This simple construction from only two parts and with the simple but secure connection to each other gives the possibility of rational and mechanical Manufacturing and thus a great saving of time and for the production of previously required workers and thus a much more economical production overall.

Nachfolgend wird die Erfindung an Hand zweier schematischer Zeichnungsskizzen in einer bevorzugten Ausführung erläutert.

Der Wickelkern 1 besteht aus einem Kunststoffspritzteil aus Polypropylen von durch Streben 5 gebildeter gitterförmiger Sturktur. Die Streben 5 umschließen einen verhältnismäßig großen Freiraum 6, so daß beim Fönen oder sonstigen Trocknen der Haare die Luft leicht durch den Wickelkern 1 und das Haar hindurchtreten kann. Auf dem Wickelkern 1 befinden sich Zapfen 2, die im Bereich ihrer Basis eine Nut 3 und an ihrem freien Ende eine Spitze 4 aufweisen. Im hier dargestellten Beispiel sitzt auf jeder Kreuzungsstelle der Streben 5 ein Zapfen 2.The winding core 1 consists of a plastic injection molded part made of polypropylene of a lattice-shaped structure formed by struts 5. The struts 5 enclose a relatively large free space 6, so that the air can easily pass through the winding core 1 and the hair when blow-drying or otherwise drying the hair. On the winding core 1 there are pins 2 which have a groove 3 in the region of their base and a tip 4 at their free end. In the example shown here, a pin 2 sits on each crossing point of the struts 5.

Das um den Wickelkern 1 herumgelegte Klettband 7 besteht im Wechsel aus einer Reihe Klettband-schlingen 8 und einer Reihe Nylongitter 10, das ebenfalls verhältnismäßig weitmaschig ist, um die Luft leicht hindurchtreten zu lassen.The Velcro 7 wrapped around the winding core 1 alternately consists of a row of Velcro loops 8 and a row of nylon grids 10, which is also relatively wide-meshed to allow the air to pass easily.

Beim Herumlegen des Klettbandes 7 um den Wickelkern 1 dringt der Zapfen 2 mit seiner Spitze 4 in das Nylongitter 10 des Klettbandes 7 ein, verhakt sich durch die Nut 3 im Klettband 7 und gewährleistet so einen festen Sitz des Klettbandes 7 auf dem Wickelkern 1.When the Velcro tape 7 is wrapped around the winding core 1, the pin 2 penetrates with its tip 4 into the nylon grid 10 of the Velcro tape 7, hooks through the groove 3 in the Velcro tape 7 and thus ensures that the Velcro tape 7 is firmly seated on the winding core 1.

Wickelkern und/oder Zapfen können aus thermoplastischem Kunststofff, Keramik, Tongut, Tonzeug, syntetischer Keramik, Blech, Aluminium oder Holz bestehen, oder aus Kombinationen dieser Materialien.The winding core and / or pin can consist of thermoplastic, ceramic, clay, clay, synthetic ceramic, sheet metal, aluminum or wood, or a combination of these materials.
