Abstract

The hair curler comprises several circumferentially closed circular cylindrical tubes (12-18) with stepped diameters and set coaxially in each other. All tubes except the end tubes (12,14) each have at least one axially extending longitudinal web (30) with apertures (22) each side. A longitudinal guide (24) ending at a distance from both tube ends is set in the axial web so that a guide element (26) provided at the end of a sleeve of adjoining tube engages permanently in same and forms the extension restrictor and also an anti-rotation member. The longitudinal guides comprise grooves and the guide elements comprise radial studs supported on the groove base.

Description

Die Erfindung betrifft einen Lockenwickler, bestehend aus mehreren umfangsgeschlossenen, kreiszylindrischen Röhren mit gestuften Durchmessern, die koaxial ineinander angeordnet und mit Schiebepassung teleskopierbar sind, im ausgezogenen Zustand des Lockenwicklers ein steifes Rohr bilden und je eine Vielzahl von Durchbrüchen und dazwischen verbleibende, einander kreuzende Stege sowie Ausziehbegrenzungsmittel aufweisen.The invention relates to a hair curler, consisting of a plurality of circumferentially closed, circular cylindrical tubes with stepped diameters, which are arranged coaxially one inside the other and are telescopic with a sliding fit, form a rigid tube in the pulled-out state of the hair curler and each have a large number of openings and intervening crosspieces and crosspieces Have pull-out limiting means.

Ein Lockenwickler dieser Art ist aus der US-A-3,835,871 bekannt. Am Übergang zwischen jeweils zwei Röhren befinden sich Ausziehbegrenzungsmittel in Form von Innen- und Außenflanschen, die miteinander Anschläge bilden. Einer der Endflansche weist am freien Ende ebenfalls einen Flansch auf, der die Röhren im eingeschobenen Zustand zusammenhält. Dieser Flansch steht jedoch einer problemlosen Montage im Wege. Der Lockenwickler ist in der Handhabung unpraktisch, weil die einzelnen Röhren relativ verdrehbar sind, was beim Aufwickeln der Locken stört.A hair curler of this type is known from US-A-3,835,871. At the transition between two tubes, there are pull-out limiting means in the form of inner and outer flanges which form stops with one another. One of the end flanges also has a flange at the free end, which holds the tubes together when pushed in. However, this flange stands in the way of easy assembly. The curler is impractical to use because the individual tubes can be rotated relatively, which interferes with the winding of the curls.

Die US-A-3,593,724 zeigt einen teleskopierbaren Lockenwickler, bestehend aus einer Außenröhre und einer Innenröhre. Die Innenröhre hat einen durchgehenden Längsschlitz, in den, eine Mehrzahl axial ausgerichteter Innenvorsprünge der Außenröhre eingreifen. Von dem Schlitz der Innenröhre zweigen Winkelschlitze ab, in die die Vorsprünge der Außenröhre einfahren können. Damit wird zwar eine Arretierung der beiden Röhren erreicht, die sowohl in Axialrichtung, als auch in Umfangsrichtung wirkt, jedoch findet eine echte Auszugsbegrenzung nicht statt, wenn die Vorsprünge beim Teleskopieren der Röhren im Schlitz der Innenröhre liegen. Außerdem ist die geschlitzte Hülse instabil und verhindert die Ausbildung des Röhrenmantels als Gitterwerk mit großflächigen Durchbrüchen.US-A-3,593,724 shows a telescopic hair curler consisting of an outer tube and an inner tube. The inner tube has a continuous longitudinal slot into which a plurality of axially aligned inner projections of the outer tube engage. Angled slots branch into the slot of the inner tube, into which the projections of the outer tube can enter. A locking of the two tubes is thus achieved, which acts both in the axial direction and in the circumferential direction, but there is no real extension limitation if the projections lie in the slot of the inner tube when telescoping the tubes. In addition, the slotted sleeve is unstable and prevents the tubular casing from being formed as a latticework with large openings.

Die US-A-2,229,841 zeigt einen Lockenwickler mit polygonal konturierten Einzelröhren, die relativ zueinander drehbar sind und je nach Drehstellung keine wackelfreie Verbindung gewährleisten. Außerdem fehlt eine wirksame Ausziehbegrenzung.US-A-2,229,841 shows a hair curler with polygonally contoured individual tubes which can be rotated relative to one another and, depending on the rotational position, do not guarantee a wobble-free connection. There is also no effective pull-out limit.

Aufgabe der Erfindung ist es, den Lockenwickler der eingangs genannten Art so auszubilden, daß die Röhren eine Vielzahl von Luftdurchtrittsöffnungen aufweisen, dennoch aber bei ausreichend geringer Wandstärke im ausgezogenen Zustand einen Lockenwickler hoher Stabilität erzeugen, der leicht herzustellen und zu montieren ist und der einen hohen Gebrauchswert dadurch hat, daß eine wirksame Ausziehbegrenzung vorhanden ist und eine relative Drehbarkeit der Röhren zueinander ausgeschlossen ist.The object of the invention is to design the hair curler of the type mentioned at the outset in such a way that the tubes have a large number of air passage openings, but nevertheless, with a sufficiently small wall thickness in the extended state, produce a hair curler of high stability which is easy to manufacture and assemble and which is high Usage value in that there is an effective pull-out limit and a relative rotation of the tubes to each other is excluded.

Diese Aufgabe wird bei einem Lockenwickler der eingangs genannten Art dadurch gelöst, daß alle Röhren allenfalls mit Ausnahme einer Endröhre jeweils mindestens einen Längssteg mit in Umfangsrichtung beidseitig angrenzenden Durchbrüchen aufweisen, daß in dem Längssteg eine im Abstand von beiden Röhrenenden endende Längsführung angeordnet ist, in die ständig ein, im Endbereich des Mantels einer benachbarten Röhre vorgesehenes Führungselement eingreift, das das Ausziehbegrenzungsmittel und zusätzlich ein Verdrehungsschutzmittel bildet.This object is achieved in a hair curler of the type mentioned in the introduction that all tubes, with the exception of one end tube, each have at least one longitudinal web with breakthroughs adjacent on both sides in the circumferential direction, in that a longitudinal guide which is spaced from both tube ends is arranged in the longitudinal web constantly engages a guide element provided in the end region of the jacket of an adjacent tube, which forms the pull-out limiting means and additionally an anti-rotation means.

Die Längsstege stabilisieren die Röhren und ermöglichen die Ausbildung der Röhrenmäntel über ihren größten Axialbereich in Form eines Gitterwerks mit schmalen, einander kreuzenden Stegen und dazwischen verbleibenden großflächigen Durchbrüchen. Diese Ausbildung ist für ein schnelles Trocknen der aufgewickelten Haare wichtig. Die Längsführungen können als durchgehende Schlitze ausgebildet sein, so daß ein zapfenförmiges Führungselement in der benachbarten Röhre in den Schlitz eingreift, wodurch gleichzeitig eine Ausziehbegrenzung und ein Verdrehungsschutz bewirkt werden. Wenn gemäß einer Ausgestaltung der Erfindung die Längsführung als Nut ausgebildet ist, die also einen Nutboden besitzt, so können an den Enden - aber auch in Zwischenstellungen - Vertiefungen im Nutboden vorgesehen werden, in die der vorzugsweise federnd gelagerte Zapfen der anderen Röhre einrastet. Eine unerwünschte Längsverschiebung der Röhren zueinander während des Gebrauches ist damit ausgeschlossen.The longitudinal webs stabilize the tubes and allow the tubular jackets to be formed over their largest axial area in the form of a lattice work with narrow, intersecting webs and large openings that remain between them. This training is important for a quick drying of the coiled hair. The longitudinal guides can be designed as continuous slots, so that a peg-shaped guide element engages in the slot in the adjacent tube, thereby simultaneously causing a pull-out limitation and protection against rotation. If according to an embodiment of the invention the longitudinal guide as Groove is formed, which thus has a groove bottom, so can be provided at the ends - but also in intermediate positions - recesses in the groove bottom, in which the preferably spring-loaded pin of the other tube engages. An undesirable longitudinal displacement of the tubes to each other during use is therefore excluded.

Die Längsstege verlaufen vorzugsweise achsparallel gemäß einer Altenative verlaufen die Längsstege schraubenlinienförmig.The longitudinal webs preferably run axially parallel according to an alternative, the longitudinal webs run helically.

Weitere vorteilhafte Merkmale und Weiterbildungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further advantageous features and developments of the invention result from the following description of an exemplary embodiment.

Ein Lockenwickler 10 besteht aus vier teleskopierbaren kreiszylindrischen Röhren, nämlich einer Endröhre 12 größten Durchmessers, einer Endröhre 14 kleinsten Durchmessers und zwei dazwischen angeordneten Innenröhren 16, 18. Alle Röhren 12-18 haben dieselbe Länge, die im Ausführungsbeispiel 65 mm beträgt. Der Außendurchmesser der größten Röhre 12 beträgt etwa 23 mm und derjenige der kleinsten Röhre 14 etwa 16 mm. Die Durchmesserstufung von Röhre zu Röhre beträgt ca. 2,2 mm und die Überlappung zweier Röhren im ausgezogenen Zustand des Wicklers 10 liegt bei 13 mm. Alle Röhre 12-18 sind an ihren Enden offen und der jeweilige Mantel besteht aus einander kreuzenden Stegen 20, die ein großlückiges Gitterwerk bilden mit einer Vielzahl großflächiger Durchbrüche 22. Mit Ausnahme der Größtröhre 12 haben alle anderen Röhren 14-18 zwei diametral gegenüberliegende Längsführungen 24, in Form von Axialschlitzen die bis nahe an die Röhrenenden heranreichen. Mit Ausnahme der Kleinströhre 14 haben alle anderen Röhren 12-16,18 zwei diametral gegenüberliegende Führungszapfen 26, die sich vom Röhrenmantel um etwa die Wandstärke der Röhren radial nach innen erstrecken und in die Längsführungen 24 der jeweils anschließenden Röhre eingreifen. Die beiden Führungszapfen 26 jeder der beiden Innenröhren 16,18 liegen in einer Axialebene, die mit der die beiden Längsführungen 24 enthaltenden zweiten Axialebene einen Winkel von 90° bildet. Dadurch wird erreicht, daß das Längsschlitzpaar 24, 24 von Röhre zu Röhre um jeweils 90° umfangsversetzt liegt. Die Röhren könnten daher voll in einander geschoben werden, wobei alle Führungszapfen 26 in einer Radialebene zu liegen kämen.A hair curler 10 consists of four telescopic circular cylindrical tubes, namely an end tube 12 of the largest diameter, an end tube 14 of the smallest diameter and two inner tubes 16, 18 arranged between them. All tubes 12-18 have the same length, which is 65 mm in the exemplary embodiment. The outer diameter of the largest tube 12 is approximately 23 mm and that of the smallest tube 14 is approximately 16 mm. The diameter gradation from tube to tube is approximately 2.2 mm and the overlap of two tubes in the extended state of the winder 10 is 13 mm. All tubes 12-18 are open at their ends and the respective jacket consists of intersecting webs 20, which form a large lattice work with a large number of large openings 22. With the exception of the large tube 12, all other tubes 14-18 have two diametrically opposed longitudinal guides 24 , in the form of axial slots that come close to the tube ends. With the exception of the small tube 14, all other tubes 12-16, 18 have two diametrically opposed guide pins 26 which extend radially inward from the tube jacket by approximately the wall thickness of the tubes and engage in the longitudinal guides 24 of the respective subsequent tube. The two guide pins 26 of each of the two inner tubes 16, 18 lie in an axial plane which forms an angle of 90 ° with the second axial plane containing the two longitudinal guides 24. It is thereby achieved that the pair of longitudinal slots 24, 24 is circumferentially offset by 90 ° from tube to tube. The tubes could therefore be pushed fully into one another, with all of the guide pins 26 coming to lie in a radial plane.

Wie Fig. 2 veranschaulicht ist die Länge der Führungsführungen 24 so bestimmt, daß jede Röhre aus seiner benachbarten Röhre im Einschubzustand des Lockenwicklers 10 etwas vorsteht. An diesen vorstehenden Enden können die Röhren erfaßt und leichter ausgezogen werden. Jede der Röhren 12-18 weist an dem, die nächst kleinere Röhre führenden Ende eine konische Schräge 28 als Übergangsabschnitt auf.As illustrated in FIG. 2, the length of the guide guides 24 is determined such that each tube protrudes somewhat from its neighboring tube when the hair curler 10 is inserted. At these projecting ends, the tubes can be gripped and pulled out more easily. Each of the tubes 12-18 has a conical bevel 28 as a transition section at the end leading the next smaller tube.

Die aus den Längsführungen 24 und den Führungszapfen 26 bestehende Führungseinrichtung bewirkt einen Schutz gegen Relativdrehung der Röhren und wirkt als Mittel zur Ausziehbegrenzung.The guide device consisting of the longitudinal guides 24 and the guide pins 26 provides protection against relative rotation of the tubes and acts as a means of limiting the pull-out.

Wie sich aus den Figuren 3 und 4 ergibt, weisen die Röhren 14, 16, 18 in ihrem jeweiligen Mantel ein Paar einander diametral gegenüber liegender Längsstege 30 auf, die einem Teil des Gitterwerks bilden. Die Längsführungen 24 sind in diesen Längsstegen 30 mittig angeordnet.As can be seen from FIGS. 3 and 4, the tubes 14, 16, 18 in their respective shells have a pair of diametrically opposed longitudinal webs 30 which form part of the latticework. The longitudinal guides 24 are arranged centrally in these longitudinal webs 30.

Die Außenseiten der das Gitterwerk bildenden Stege 20, 30 sind mit einer Florbeschichtung 32 versehen. Dieser Flor steht im ausgezogenen Zustand des Teleskopwicklers 10 radial vom Röhrenmantel ab und dient bei der Handhabung des Lockenwicklers zur Verankerung der Haare. Beim Zusammenschieben des Lockenwicklers 10 legt sich der Flor um und bewirkt einen Reibschluß zwischen den Röhren, der dafür sorgt, daß eine gewisse Zugkraft notwendig ist, um eine oder mehrere Röhren auszufahren.The outer sides of the webs 20, 30 forming the latticework are provided with a pile coating 32. This pile protrudes radially from the tube jacket in the extended state of the telescopic roller 10 and serves to anchor the hair when handling the hair roller. When the hair curler 10 is pushed together, the pile folds and creates a frictional connection between the tubes, which ensures that a certain tensile force is necessary in order to extend one or more tubes.

Der Führungszapfen 26 kann entweder als einstückiger Vorsprung beim Spritzgießen der Röhren angeformt oder als separater Zapfen ausgebildet sein, der z.B. in eine Rastbohrung der jeweiligen Röhre eingedrückt und dabei verrastet wird.The guide pin 26 can either be integrally formed as a one-piece projection during the injection molding of the tubes or can be designed as a separate pin which, e.g. is pressed into a locking hole of the respective tube and thereby locked.

FIG. 5 zeigt eine Variante, bei der die Längsführung 24 als Nut ausgebildet ist, in die der Zapfen 26 hineinpaßt. Dieser ist zweiteilig ausgebildet und umfaßt eine Außenhülse 34, die in eine Radialbohrung der jeweiligen Röhre eingesetzt ist, sowie ein bodenseitig geschlossene Innenhülse 36 mit eingebauter Feder 38. An den beiden Enden der Längsführung 24 und in deren Mitte sind jeweils Vertiefungen in Form von Durchgangsbohrungen 40 vorgesehen, in die die Zapfen 26 im eingeschobenen Zustand der Röhren, im halbausgezogenen Zustand und in vollausgezogenen Zustand einrasten.FIG. 5 shows a variant in which the longitudinal guide 24 is designed as a groove into which the pin 26 fits. This is formed in two parts and comprises an outer sleeve 34, which is inserted into a radial bore of the respective tube, and an inner sleeve 36 closed at the bottom with built-in spring 38. At the two ends of the longitudinal guide 24 and in the middle there are depressions in the form of through holes 40 provided, into which the pins 26 engage when the tubes are inserted, in the half-extended state and in the fully extended state.

Im Ausführungsbeispiel fehlt bei der größten Röhre 12 das Längsführungspaar und bei der kleinsten Röhre 14 der Führungszapfen 26. Es versteht sich, daß das Führungsprinzip auch umgekehrt werden kann. Die Führungszapfen 26 sind dann jeweils den hinteren Endbereichen der Röhren 14, 16 und 18 zugeordnet und stehen nicht radial nach innen sondern nach außen vor.In the exemplary embodiment, the pair of longitudinal guides is missing in the largest tube 12 and the guide pin 26 in the smallest tube 14. It is understood that the guide principle can also be reversed. The guide pins 26 are then assigned to the rear end regions of the tubes 14, 16 and 18 and do not project radially inwards but outwards.

Die Ausführung, bei der die Zapfen 26 radial nach außen zeigen, ermöglicht in Verbindung mit zwei einander jeweils diametral gegenüber liegenden schlitzförmigen oder nutenförmigen Längsführungen 24 einen gemeinsamen Radialstift zu verwenden, dessen Enden die Zapfen 26 bilden. Dieser Radialstift durchsetzt also die jeweilige Röhre vollständig. Er läßt sich leicht zweiteilig mit eingebauter Feder ausbilden, der genauso einfach montiert werden kann. Der gezeigte viergliedrige Lockenwickler besitzt dann drei solcher Radialstifte, von denen die beiden äußeren parallel liegen und der mittlere quer dazu angeordnet ist. Im eingefahrenen Zustand berühren die drei Radialstifte einander.The embodiment in which the pins 26 point radially outward makes it possible, in conjunction with two slot-shaped or groove-shaped longitudinal guides 24 lying diametrically opposite one another, to use a common radial pin, the ends of which form the pins 26. This radial pin completely penetrates the respective tube. It can be easily formed in two parts with a built-in spring, which can be installed just as easily. The four-section hair curler shown then has three such radial pins, of which the two outer ones are parallel and the middle one is arranged transversely thereto. When retracted, the three radial pins touch each other.

Eine weitere nicht dargestellt Alternative besteht darin, an den Enden von drei der vier Röhren längliche Lappen an drei Seiten auszustanzen bzw. bei der Spritzgußformung entsprechend zu trennen, so daß an der vierten Seite eine Biegezone entsteht, mit welcher die Lappen mit dem jeweiligen Röhrenmantel verbunden bleiben. Diese Lappen wirken dann als Federzungen und tragen an dem, dem Biegebereich gegenüber liegenden freien Ende den Zapfen 26. Beim Auflaufen der Zapfen auf den Nutboden der Längsführungen 24 weichen die Enden der Lappen geringfügig in radialer Richtung aus, ohne daß dies die Teleskopierbarkeit der Röhren unzulässig behindert. Die Lappen können in Längsrichtung der Röhren, aber auch genauso gut in Umfangsrichtung orientiert werden.Another alternative, not shown, is to punch out elongated tabs on three sides at the ends of three of the four tubes or to separate them accordingly during injection molding, so that a bending zone is formed on the fourth side, with which the tabs are connected to the respective tube jacket stay. These tabs then act as spring tongues and carry the pin 26 at the free end opposite the bending area. When the pins run onto the groove bottom of the longitudinal guides 24, the ends of the tabs move slightly in the radial direction, without this impermitting the telescopic nature of the tubes with special needs. The tabs can be oriented in the longitudinal direction of the tubes, but also just as well in the circumferential direction.

Anstatt des dargestellten 4-gliedrigen Lockenwicklers kann dieser auch aus 2 oder 3 Röhren aber auch aus mehr als 4 Röhren bestehen.Instead of the 4-section hair curler shown, it can also consist of 2 or 3 tubes but also of more than 4 tubes.

Im Ausführungsbeispiel sind die Längsführungen 24 achsparallel also geradlinig angeordnet. Es liegt jedoch ausdrücklich im Rahmen der Erfindung, die Längsführungen auf schraubenlinienförmigen Bahnen anzuordnen, wobei die Steigung der Schraubenlinie vorzugsweise so bemessen ist, daß für die volle Ausziehbewegung eine Relativdrehung von höhcstens 360° ausreicht.In the exemplary embodiment, the longitudinal guides 24 are arranged axially parallel, that is to say in a straight line. However, it is expressly within the scope of the invention to arrange the longitudinal guides on helical paths, the pitch of the helical line preferably being such that a relative rotation of at most 360 ° is sufficient for the full extension movement.
