Abstract

In a hair curling rod having retractable bristles passing through apertures in a cylindrical body for winding up the hair and a device for directing a stream of heated air through the outlet apertures, the bristles or prongs are retractable independency on the temperature of the heated air stream. Preferably, the bristles are secured at one thereof to a movable support controlled by a temperature dependent element of a shape-memory alloy situated in the stream of heated air to expand or contract in response to predetermined temperatures.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 und einen Lockenstab nach dem Oberbegriff des Anspruchs 2.The invention relates to a method according to the preamble of claim 1 and a curling iron according to the preamble of claim 2.

Nach der EP-A-0 168 099 ist ein Lockenstab mit Lufttrocknung - sogenanntes Air-Curl-Gerät - mit einziehbaren Borsten oder Zinken bekannt, damit die Locke im umgeformten Zustand vom Wickelkörper abgestreift werden kann und dann in der Umgebungsluft konditioniert. Das Einziehen der Borsten oder Zinken erfolgt über Bedienelemente, die entweder im Handgriff oder an der Spitze des Wickelkörpers angebracht sind, was zusätzliche Handgriffe bzw. die Aufmerksamkeit des Friseurs erfordert.According to EP-A-0 168 099, a curling iron with air drying - so-called air curl device - with retractable bristles or tines is known so that the curl can be stripped from the winding body in the deformed state and then conditioned in the ambient air. The bristles or tines are retracted using controls that are attached either in the handle or at the tip of the winding body, which requires additional handles or the hairdresser's attention.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bzw. einen Lockenstab vorzuschlagen, bei welchem die zusätzlichen Handgriffe bzw. die Aufmerksamkeit des Friseurs nicht erforderlich sind.The object of the present invention is to propose a method or a curling iron in which the additional handles or the attention of the hairdresser are not required.

Diese Aufgabe wird erfindungsgemäß nach dem kennzeichnenden Teil des Anspruchs 1 bzw. Anspruchs 2 gelöst.This object is achieved according to the characterizing part of claim 1 and claim 2.

Die Erfindung hat den Vorteil, daß die Borsten oder Zinken ohne einen Bedienvorgang eingezogen werden, wenn Haare auf dem Wickelkörper aufgewickelt sind. Der Erfindung liegt die Erkenntnis zugrunde, daß durch das Aufwickeln der Haare der Strömungswiderstand im Bereich der Austrittsöffnungen größer wird. Dadurch verringert sich der Luftstrom, was wiederum bei vorgegebener Heizleistung zu einer Temperaturerhöhung führt. Erreicht dabei die Lufttemperatur einen vorgegebenen Wert, so werden die Borsten oder Zinken eingezogen, so daß die Locke, ohne abgewickelt zu werden, vom Wickelkörper abgestreift werden kann.The invention has the advantage that the bristles or tines are retracted without an operation when hair is wound on the winding body. The invention is based on the finding that the flow resistance in the region of the outlet openings increases as a result of the hair being wound up. This reduces the air flow, which in turn leads to an increase in temperature for a given heating output. When the air temperature reaches a predetermined value, the bristles or prongs are drawn in so that the curl can be stripped off the winding body without being unwound.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im nebengeordneten Anspruch 2 angegebenen Erfindung möglich.The measures listed in the subclaims allow advantageous developments and improvements of the invention specified in the independent claim 2.

Ein Ausführungsbeispiel der Erfindung ist anhand mehrerer Figuren dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigt:

Fig. 1
einen Teil des Ausführungsbeispiels mit hervorstehenden Borsten und
Fig. 2
mit eingezogenen Borsten.
An embodiment of the invention is shown with reference to several figures and explained in more detail in the following description. It shows:
Fig. 1
a part of the embodiment with protruding bristles and
Fig. 2
with retracted bristles.

Gleiche Teile sind in den Figuren mit gleichen Bezugszeichen versehen. Der Übersichtlichkeit halber wurde auf die vollständige Darstellung des Handgriffs verzichtet. Ferner wurde aus Symmetriegründen jeweils nur eine Hälfte des Wickelkörpers und der Verstellvorrichtung dargestellt.Identical parts are provided with the same reference symbols in the figures. For the sake of clarity, the handle is not shown in full. Furthermore, for reasons of symmetry, only half of the winding body and the adjusting device were shown.

Aus einem Gehäuse 1 wird ein Luftstrom 2, der mit Hilfe eines Gebläses und eines Heizers erzeugt wird, in das Innere des Wickelkörpers 3 geleitet, aus welchem der Luftstrom durch Austrittsöffnungen 4 austritt. Innerhalb des Wickelkörpers 3 ist axial verschiebbar eine Verstellvorrichtung 5 vorgesehen, welche gleichzeitig als Haltevorrichtung für Borsten 6 dient. Die Verstellvorrichtung 5 ist ebenfalls zylindrisch und an ihrem Umfang mit Öffnungen 7 für den Luftstrom versehen.From a housing 1, an air flow 2, which is generated with the aid of a blower and a heater, is conducted into the interior of the winding body 3, from which the air flow exits through outlet openings 4. An adjusting device 5 is provided axially displaceably within the winding body 3 and serves at the same time as a holding device for bristles 6. The adjusting device 5 is also cylindrical and is provided on its circumference with openings 7 for the air flow.

Die Borsten 6 sind zu Büscheln zusammengefaßt, von denen jeweils einer durch eine Austrittsöffnung 4 nach außen ragt.The bristles 6 are combined into tufts, one of which protrudes outwards through an outlet opening 4.

In axialer Richtung ist die Verstellvorrichtung 5 von einem temperaturabhängigen Element 8 gehalten, das aus einer Legierung mit Formgedächtnis besteht. Derartige Legierungen sind an sich bekannt und beispielsweise in "Zeitschrift für wirtschaftliche Fertigung", 81. Jahrgang 1986, Heft 12, Seite 703 bis 708 beschrieben. Als Beispiele für derartige Legierungen werden in der Literatur NiTi, Cu-Zn-Al und Cu-Al-Ni genannt. Verschiedene Legierungen und eine Vielzahl von Formteilen sind auf dem Markt erhältlich, wobei die Temperatur, bei welcher die Formänderung erfolgt, in weiten Grenzen wählbar ist.In the axial direction, the adjusting device 5 is held by a temperature-dependent element 8, which consists of an alloy with shape memory. Alloys of this type are known per se and are described, for example, in "Journal for Economic Manufacturing", 81st year 1986, number 12, pages 703 to 708. Examples of such alloys are found in the literature as NiTi, Cu-Zn-Al and Called Cu-Al-Ni. Various alloys and a large number of molded parts are available on the market, and the temperature at which the change in shape takes place can be selected within wide limits.

Während bei der in Fig. 1 dargestellten Stellung keine Haare auf den Wickelkörper aufgewickelt sind und die Temperatur des Luftstroms unterhalb der für die Formänderung erforderlichen Temperatur liegt, zeigt Fig. 2 das Ausführungsbeispiel nach dem Haare aufgewickelt wurden (nicht dargestellt) und dadurch die Temperatur des Luftstroms gestiegen ist (Wärmestau). Das temperaturabhängige Element 8 hat seine Form derart geändert, daß die Verstellvorrichtung 5 axial in Richtung auf den Handgriff 1 verschoben ist. Die Austrittsöffnungen 4 stehen in dieser Stellung nicht mehr den Befestigungspunkten der Borsten gegenüber, so daß die Borsten sichtbar eingezogen sind. Sobald der Wickelkörper aus der Haarlocke herausgezogen wird, sinkt die Temperatur des Luftstroms wieder, so daß die Verstellvorrichtung 5 die in Fig. 1 dargestellte Stellung einnimmt und die Borsten wieder ausgestreckt werden.While in the position shown in Fig. 1 no hair is wound on the bobbin and the temperature of the air flow is below the temperature required for the shape change, Fig. 2 shows the embodiment after the hair was wound (not shown) and thereby the temperature of the Air flow has increased (heat build-up). The temperature-dependent element 8 has changed its shape such that the adjusting device 5 is axially displaced in the direction of the handle 1. In this position, the outlet openings 4 are no longer opposite the attachment points of the bristles, so that the bristles are visibly drawn in. As soon as the bobbin is pulled out of the lock of hair, the temperature of the air flow drops again, so that the adjusting device 5 assumes the position shown in FIG. 1 and the bristles are stretched out again.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern kann im Rahmen des Fachmännischen verschiedenartig ausgeführt und weitergebildet werden. So ist beispielsweise die Verwendung mehrerer temperturabhängiger Elemente 8 mit gegebenenfalls verschiedenen Kennlinien möglich. Außerdem kann das Einziehen und/oder das Ausstrecken der Borsten gegebenenfalls auch zusätzlich manuell erfolgen.The invention is not limited to the exemplary embodiment shown, but can be embodied and developed in various ways within the scope of the expert. For example, the use of several temperature-dependent elements 8 with possibly different characteristic curves is possible. In addition, the drawing in and / or the extension of the bristles can optionally also be carried out manually.

Ferner können als temperaturabhängiges Element auch andere Formteile aus einer Legierung mit Formgedächtnis verwendet werden, beispielsweise eine Schraubenfeder, deren Länge sich mit der Temperatur ändert. Der erfindungsgemäße Lockenstab kann auch mit einem drehbaren Wickelkörper vorgesehen sein.Furthermore, other molded parts made of an alloy with shape memory can be used as a temperature-dependent element, for example a helical spring, the length of which changes with temperature. The curling iron according to the invention can also be provided with a rotatable winding body.

Anstelle der axialen Verschiebung der Borstenhalterung kann auch eine Drehbewegung vorgesehen sein. Bei der Verwendung von Zinken können diese in einer drehbaren Halterung gelagert sein. Die Erzeugung einer Drehbewegung kann direkt mit einem entsprechenden temperaturabhängigen Element erfolgen. So sind beispielsweise Teile aus einer Legierung mit Formgedächtnis erhältlich, welche die Form einer Spreizfeder aufweisen. Ein solches Teil kann mit seiner Wendel gleichachsig im Lockenstab angeordnet sein, wobei ein Ende gehäusefest und das andere Ende mit der drehbaren Borsten- oder Zinkenhalterung verbunden ist. Zur Erzeugung einer Drehbewegung eignen sich jedoch auch lineare temperaturabhängige Elemente, deren Bewegung durch geeignete Maßnahmen, beispielsweise eine Kulissenführung, in eine Drehbewegung umgesetzt wird.Instead of the axial displacement of the bristle holder, a rotary movement can also be provided. If tines are used, they can be mounted in a rotatable holder. A rotary movement can be generated directly with a corresponding temperature-dependent element. For example, parts made of an alloy with shape memory are available which have the shape of an expansion spring. Such a part can be arranged with its helix coaxially in the curling iron, one end being fixed to the housing and the other end connected to the rotatable bristle or tine holder. However, linear temperature-dependent elements are also suitable for generating a rotary movement, the movement of which elements is converted into a rotary movement by suitable measures, for example a link guide.
