Abstract

1. Hair curler with an elongate winding body (14), on which the hairs are to be fixed with the aid of a tensioning band (2, 3, 13) to be stretched between the longitudinal ends (15, 16) of the winding body at spigots (11, 12), wherein the spigots (11, 12) are during casting moulded to the ends of the tensioning band and constructed as coupling and closure elements for insertion in receptacle holes (17, 18) provided at the end faces of the winding body, characterised thereby, that the winding body (14) is hollow-moulded and the openings, which arise at its end faces due to mould cores, are used as receptacles holes (17, 18) for the spigots (11, 12) and that the tensioning band (2, 3, 13) is produced by an injection-moulding process from a rubber-elastic polyurethane (PUR) to be processed thermoplastically and the elasticity of the material of the tensioning band (2, 3, 13) is to be augmented by elasticity of shape, in particular through moulded-in holes (5, 7) with rim strips (4, 6) of substantially uniform width.

Description

Die Erfindung betrifft einen Haarwellwickler mit einem langgestreckten Wickelkörper, auf dem die Haare mit Hilfe eines zwischen den Wickelkörperlängsenden an Zapfen aufzuspannenden Spannbandes festzulegen sind, wobei die Zapfen, beim Giessen an die Enden des Spannbandes angeformt, als Kupplungs- und Verschlusselemente zum Einsetzen in an den Stirnseiten des Wickelkörpers vorgesehenen Aufnahmelöchern ausgebildet sind.The invention relates to a hair curler with an elongated bobbin, on which the hair is to be fixed with the aid of a tensioning band to be clamped between the longitudinal ends of the bobbin, the pins being molded onto the ends of the tensioning band during casting, as coupling and closure elements for insertion into the End holes of the winding body provided receiving holes are formed.

Ein derartiger Haarwellenentwickler ist aus der US-A-2 525 750 bekannt.Such a hair wave developer is known from US-A-2 525 750.

Derartige Wickelkörper werden im allgemeinen im wesentlichen zylinderförmig mit an den Zylinderlängsenden hyperboloidförmig ansteigendem Durchmesser hergestellt. Bei Anwendung wickelt man die Haare um den Wickelkörper und legt die aufgewickelten Haare mittels eines Spannbandes fest, das unter gewisser elastischer Dehnung an den Längsenden des Wickelkörpers zu kuppeln ist.Such bobbins are generally produced in a substantially cylindrical shape with a hyperboloidally increasing diameter at the longitudinal ends of the cylinders. In use, the hair is wrapped around the winding body and the wound hair is fixed by means of a tension band which is to be coupled to the longitudinal ends of the winding body with a certain elastic stretch.

Zum Befestigen der gewickelten Haare auf dem Wickelkörper vorgenannter Art werden meist extrudierte Gummibänder verwendet, die nach dem Extrudieren abzuteilen und in einem weiteren Arbeitsgang durch Stanzen mit Befestigungslöchern zu versehen sind. Abgesehen von dem Herstellungsaufwand besteht ein Nachteil der bekannten Spannbänder darin, dass bei einer schnelleren «Alterung» in der Wellflüssigkeit keine chemische Neutralität mehr gegeben ist.To fasten the wound hair on the winding body of the aforementioned type, extruded rubber bands are mostly used, which must be separated after extrusion and punched with fastening holes in a further operation. Apart from the manufacturing effort, a disadvantage of the known tensioning straps is that, in the case of faster "aging" in the corrugated liquid, there is no longer any chemical neutrality.

Dieser aus der US-A-2 525 750 bekannte Haarwellwickler weist ein gegossenes Spannband auf, welches mit Schlitzen versehen ist, die vor der ersten Ingebrauchnahme des Haarwellwicklers das Spannband nicht durchdringen. Ferner ist der Haarwellwickler gemäss US-A-2 525 750 als zylindrische Hülse aus absorbierendem Material wie Baumwolle oder Papier ausgebildet.This hair curler known from US-A-2 525 750 has a cast tension band which is provided with slits which do not penetrate the tension band before the hair curler is first used. Furthermore, the hair curler according to US-A-2 525 750 is designed as a cylindrical sleeve made of absorbent material such as cotton or paper.

Der Erfindung liegt die Aufgabe zugrunde, den Aufwand zum Herstellen der Spannbänder zu vermindern und die chemische Beständigkeit der Bänder zu erhöhen.The invention has for its object to reduce the effort for producing the tensioning straps and increase the chemical resistance of the straps.

Bei einem Haarwellwickler der eingangs bezeichneten Art wird diese Aufgabe gemäss der Erfindung dadurch gelöst, dass der Wickelkörper hohlgespritzt ist und die an seinen Stirnseiten durch Formkerne entstehenden Öffnungen als Aufnahmelöcher für die Zapfen vorgesehen sind, und dass das Spannband aus einem thermoplastisch zu verarbeitenden, gummielastischen Polyurethan (PUR) nach dem Spritzgussverfahren hergestellt und die Materialelastizität des Spannbandes durch Formelastizität, insbesondere durch eingespritzte Löcher mit im wesentlichen gleichmässig breiten Randstreifen, ergänzt ist.In the case of a hair curler of the type mentioned at the outset, this object is achieved according to the invention in that the winding body is injection-molded in a hollow manner and the openings formed on its end faces by mold cores are provided as receiving holes for the pins, and in that the tensioning band is made of a rubber-elastic, elastomeric polyurethane (PUR) manufactured by the injection molding process and the material elasticity of the tensioning strap is supplemented by formula elasticity, in particular by injected holes with essentially uniformly wide edge strips.

Durch die Erfindung wird es möglich, allein durch Verspritzen elastischer Kunststoffmateriaiien ein Spannband zu erhalten, dessen Elastizität zum Kuppeln mit dem mit Haaren bewickelten Wickelkörper ausreicht, dessen Material sich chemisch neutral zur Anwendungsflüssigkeit bzw. zum Wellmittel verhält und das durch die vorgesehene Ergänzung der Materialelastizität durch Formelastizität mit einem für die praktische Anwendung ausreichend geringen Kraftaufwand zu dehnen ist. Hierbei wird die Materialelastizität durch eingespritzte Löcher ergänzt.The invention makes it possible to obtain a tensioning band solely by spraying elastic plastic materials, the elasticity of which is sufficient for coupling with the winding body wound with hair, the material of which is chemically neutral to the application liquid or the corrugating agent and by the intended addition of the material elasticity The elasticity of the formula must be stretched with a force that is sufficiently low for practical use. The material elasticity is supplemented by injected holes.

Da ferner der Wickelkörper hohlgespritzt ist, weist er als Reservoir für ein Wellmittel einen parallel zur Mittelachse verlaufenden Hohlraum auf. Zum Herstellen dieses Hohlraumes beim Spritzen werden ausser den äusseren Formbakken zusätzliche innere Spritzgusswerke, wie Kerne oder Schieber, benötigt. Letztgenannte Werkzeuge haben an den nicht mit Haaren zu bewikkeinden Stirnseiten des Wickelkörpers Löcher zur Folge, die mit den Zapfen des Spannbandes zu verschliessen sind, wodurch verhindert wird, dass bei Anwendung flüssigen Wellmittels dieses stirnendseitig aus dem Wickelkörper austritt. Da die zum Ankuppeln des Spannbandes vorgesehenen Zapfen als Verschlusselemente für die an den Stirnseiten des Wickelkörpers verbleibenden (Kern-)Löcher in einem Arbeitsgang beim Spritzgiessen mit an das Spannband angeformt werden, werden die Kosten für das Herstellen und Einsetzen sonst üblicher gesonderter Verschlussstopfen bei hohlgespritzten Wickelkörpern eingespart. Das Anspritzen der Zapfen als Kupplungs- und Verschlusselemente zum Einsetzen in die Löcher der Wickelkörperstirnseiten bedeutet praktisch keinen Zusatzaufwand.Furthermore, since the winding body is injection-molded in a hollow manner, it has a cavity running parallel to the central axis as a reservoir for a corrugating agent. In addition to the outer mold blocks, additional internal injection molding units, such as cores or slides, are required to produce this cavity during spraying. The latter tools result in holes on the end faces of the winding body which are not to be covered with hair, which holes are to be closed with the pins of the tensioning band, thereby preventing liquid waving agent from exiting the end face of the winding body when using liquid. Since the pins provided for coupling the tensioning strap are molded onto the tensioning strap as closure elements for the (core) holes remaining on the end faces of the winding body in one operation during injection molding, the costs for producing and inserting otherwise customary sealing plugs in the case of hollow-molded winding bodies saved. The injection molding of the pins as coupling and locking elements for insertion into the holes in the end faces of the winding body means practically no additional effort.

Als Material für das Spannband kommt in Betracht:The material for the strap is:

Thermoplastisches Polyurethan-Elastomer, hergestellt durch Umsetzung einer Mischung von Butandiol und einem Polymerendiol mit einem Molekulargewicht von 800 bis 3000 auf Ester- und/ oder Etherbasis mit Diphenylmetandiisocyanat, wobei die Mengenverhältnisse der Ausgangsstoffe nach dem bekannten Stand der Technik so gewählt werden, dass das entstehende Produkt nach thermoplastischer Verarbeitung bei Raumtemperatur eine Shore-Härte nach DIN 53505 von 75 bis 85 hat.Thermoplastic polyurethane elastomer, produced by reacting a mixture of butanediol and a polymer diol with a molecular weight of 800 to 3000 on an ester and / or ether basis with diphenylmetanediisocyanate, the proportions of the starting materials being chosen according to the known prior art so that the resultant Product after thermoplastic processing at room temperature has a Shore hardness according to DIN 53505 of 75 to 85.

Anhand der schematischen Darstellung von Ausführungsbeispielen werden weitere Einzelheiten der Erfindung näher erläutert. Es zeigen:

  • Fig. 1 und 2 verschieden geformte Spannbänder in der Draufsicht;
  • Fig. 3 ein Spannband in Seitenansicht und
  • Fig. 4 einen Wickelkörper mit aufgesetztem Spannband.
Further details of the invention are explained in more detail on the basis of the schematic representation of exemplary embodiments. Show it:
  • Figures 1 and 2 differently shaped straps in plan view.
  • Fig. 3 is a strap in side view
  • Fig. 4 shows a winding body with a tension band attached.

Fig. 1 und 2 zeigen zwei Spannbänder 2 und 3, deren Materialelastizität durch Formelastizität ergänzt ist. Das Spannband 2 von Fig. 1 besteht im wesentlichen aus den Randstreifen 4 von mit der Spitze aneinander gereihten Rauten 5. Ähnlich besteht das Spannband 3 von Fig. 2 aus den Randstreifen 6 aneinander gereihter Kreislöcher 7. An den Längsenden besitzen die Spannbänder 2 und 3 Zapfen 11 und 12, wobei dem Zapfen 11 eine Grifflasche 10 zugeordnet ist.1 and 2 show two straps 2 and 3, the material elasticity of which is supplemented by formula elasticity. The tensioning strap 2 of FIG. 1 essentially consists of the edge strips 4 of diamonds 5 lined up with the tip. Similarly, the tensioning strap 3 of FIG. 2 consists of the edge strips 6 of circular holes 7 lined up with one another. The tensioning straps 2 and 3 have at the longitudinal ends Pins 11 and 12, the tab 11 being assigned a grip tab 10.

Die insbesondere aus Fig. 3 ersichtlichen Zapfen 11 und 12 werden unmittelbar beim Herstellen des Spannbandes nach dem Spritzgussverfahren mit angeformt. Im übrigen kann das in Fig. 3 in Seitenansicht gezeigte Spannband 13 irgendeine Ausgestaltung entsprechend Fig. 1 oder 2 haben. Das Spannband 13 mit integrierten Zapfen 11, 12 greift im Anwendungsfall in die stirnseitigen Aufnahmelöcher 17, 18 des Wickelkörpers von Fig. 4 ein, welcher als Hohlkörper so gespritzt oder auf eine andere Weise geformt ist, dass an seinen Längsenden 15 und 16, z.B. von einem Kern oder Schieber her, Löcher 17 und 18 verbleiben. In diese Öffnungen 17, 18 werden die als Kupplungs-und Verschlusselemente ausgebildeten Zapfen 11, 12 eingesetzt, so dass sie die Öffnungen 17, 18 verschliessen und der Austritt von gegebenenfalls benutztem Wellmittel an den Längsenden 15 und 16 vermieden wird. Die Zapfen 11, 12 entstehen zugleich und in einem Arbeitsgang beim Spritzgiessen des Spannbandes 13 gemäss Fig. 3. In Fig. 4 ist dargestellt, wie das Spannband 13 mit angeformten Zapfen 11 und 12 um den Wickelkörper 14 zu legen ist, wie die Zapfen 11, 12 in den Löchern 17, 18 zu arretieren sind und wie die Löcher 17, 18 dabei verschlossen werden. Die Löcher 5, 7 der Spannbänder 2, 3 werden ebenfalls beim Spritzgiessen des Bandes mit eingespritzt. Das erfindungsgemässe Spannband soll aus einem dauerelastischen, gegenüber dem zu verwendenden Wellmittel chemisch neutralen und mit relativ geringer Kraft zu dehnenden Kunststoff hergestellt werden. Bei Versuchen hat sich ergeben, dass das von der Firma Elastogran GmbH, Lemförde, unter dem Handelnamen «Elastollan» gelieferte dauerthermoplastische Polyurethan- «Elastomer» die gestellten Anforderungen besonders gut erfüllt. Es handelt sich hierbei um das obige thermoplastisch zu verarbeitende, gummielastische Polyurethan.The pins 11 and 12, which can be seen in particular in FIG. 3, are also molded on directly during the manufacture of the tensioning band after the injection molding process. Otherwise, in Fig. 3 in Side strap 13 shown have any configuration corresponding to FIG. 1 or 2. The strap 13 with integrated pin 11, 12 engages in the application in the end receiving holes 17, 18 of the winding body of Fig. 4, which is injected as a hollow body or shaped in another way that at its longitudinal ends 15 and 16, for example a core or slider forth, holes 17 and 18 remain. The pins 11, 12 designed as coupling and closure elements are inserted into these openings 17, 18, so that they close the openings 17, 18 and the escape of any corrugation agent that may be used is avoided at the longitudinal ends 15 and 16. The pins 11, 12 are formed simultaneously and in one operation during the injection molding of the tensioning strap 13 according to FIG , 12 are to be locked in the holes 17, 18 and how the holes 17, 18 are closed. The holes 5, 7 of the tensioning straps 2, 3 are also injected during the injection molding of the strap. The tensioning strap according to the invention is to be produced from a permanently elastic plastic which is chemically neutral with respect to the corrugating agent to be used and can be stretched with relatively little force. Tests have shown that the permanent thermoplastic polyurethane "elastomer" supplied by Elastogran GmbH, Lemförde, under the trade name "Elastollan" fulfills the requirements particularly well. This is the above-mentioned thermoplastic rubber-elastic polyurethane.
