Definitions
- the invention relates to a curling iron with retractable bristles or tines, in which a heated air flow can be guided through outlet openings in a cylindrical winding body.
- the object of the present invention is to propose a curling iron in which the bristles or tines are automatically drawn in.
- a temperature-dependent element made of a shape memory alloy is preferably provided in the air flow.
- 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.
- an air stream 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 stream 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.
- the bristles 6 are combined into tufts, one of which projects outwards through an outlet opening 4.
- the adjusting device 5 is held by a temperature-dependent element 8, which consists of an alloy with shape memory.
- 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 Production", 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.
- 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.
- the outlet openings 4 are no longer opposite the attachment points of the bristles, so that the bristles are visibly drawn in.
- 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.
- 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.
- the use of several temperature-dependent elements 8 with possibly different characteristic curves is possible.
- the drawing in and / or the extension of the bristles can optionally also be done manually.
- molded parts made of an alloy with shape memory can be used as a temperature-dependent element, for example a coil spring, the length of which changes with temperature.
- the curling iron according to the invention can also be provided with a rotatable winding body.
- 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.
- 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.
- linear temperature-dependent elements are also suitable for generating a rotary movement, the movement of which is converted into a rotary movement by suitable measures, for example a link guide.

Abstract
Description
Die Erfindung betrifft einen Lockenstab mit einziehbaren Borsten oder Zinken, bei welchem ein erwärmter Luftstrom durch Austrittsöffnungen in einem zylindrischen Wickelkörper führbar ist.The invention relates to a curling iron with retractable bristles or tines, in which a heated air flow can be guided through outlet openings in a cylindrical winding body.
Bei bekannten Lockenstäben mit Lufttrocknung - sogenannten Air-Curl-Geräten -, sind einziehbare Borsten oder Zinken bekannt, damit die Locke im umgeformten Zustand vom Wickelkörper entfernt 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.In known curling irons with air drying - so-called air curl devices - retractable bristles or tines are known so that the curl can be removed from the winding body in the deformed state and then conditioned in the ambient air. The bristles or tines are retracted using control elements 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, einen Lockenstab vorzuschlagen, bei welchem die Borsten oder Zinken automatisch eingezogen werden.The object of the present invention is to propose a curling iron in which the bristles or tines are automatically drawn in.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Borsten oder Zinken in Abhängigkeit von der Temperatur des Luftstroms einziehbar sind. Dabei ist vorzugsweise im Luftstrom ein temperaturabhängiges Element aus einer Formgedächtnis-Legierung vorgesehen.This object is achieved in that the bristles or tines are retractable depending on the temperature of the air stream. A temperature-dependent element made of a shape memory alloy is preferably provided in the air flow.
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 Hauptanspruch angegebenen Erfindung möglich.Advantageous further developments and improvements of the invention specified in the main claim are possible through the measures listed in the subclaims.
Ausführungsbeispiele der Erfindung sind in der Zeichnung 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.
- Fig. 1 shows 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 one 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
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 projects 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
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 winding body 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-
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-
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 coil 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 is converted into a rotary movement by suitable measures, for example a link guide.
