Description

Die Erfindung betrifft ein Bügeleisen nach dem Oberbegriff des Anspruchs 1.The invention relates to an iron according to the preamble of claim 1.

Die Metallsohle ist mit den Mitteln zum Beheizen, meist einem gut wärmeleitendendem Metallschuh, beispielsweise aus Aluminiumguß, verbunden. Eine formschlüssige Verbindung zwischen der Metallsohle und dem Metallschuh wird nach einem ersten Verfahren erreicht, indem ein Zuschnitt der Metallsohle unter den Metallschuh gelegt und dann über den Schuh gebogen wird. Dabei entsteht ein abgerundeter Abschluß der Gleitfläche. Ein dem Oberbegriff des Anspruchs 1 entsprechender Bügeleisen mit Metallschuh und Metallsohle ist z.B. aus dem Dokument BE-A-500 170 bekannt. Bei der üblicherweise annähernd dreieckigen Bügelfläche, deren vordere Spitze zum Bügeln beengter Stellen wie die Umgebung von Knöpfen, Rüschen, Biesen etc. verwendet wird, kommt es darauf an, daß die Spitze, aber auch die hinteren Enden der Bügelfläche ein einwandfreies und schonendes Bügeln gewährleisten. Der abgerundete Abschluß der Gleitfläche schafft jedoch, bezogen auf die Gleitfläche, einen steilen Anstieg von der Gleitfläche zum Gehäuse, der verhindert, daß beengte Stellen zufriedenstellend gebügelt werden könnne. Zudem entstehen beim Biegen der Sohle an der Spitze und an den hinteren Ecken der Metallsohle Riefen und Auffaltungen, da der Kantenbereich an der Spitze und an den Ecken stark komprimiert wird. In den Riefen verfangen sich häufig Falten oder Knöpfe, so daß es zu Beschädigungen am Bügelgut kommt.The metal sole is with the means for heating, usually a good heat conductor Metal shoe, for example made of cast aluminum, connected. A positive connection is between the metal sole and the metal shoe according to a first method achieved by placing a cut of the metal sole under the metal shoe and then is bent over the shoe. This creates a rounded end of the sliding surface. An iron corresponding to the preamble of claim 1 with metal shoe and metal sole is e.g. from document BE-A-500 170 known. With the usually approximately triangular ironing surface, the front tip for ironing tight spaces such as the area around buttons, frills, tucks etc. it is important that the tip, but also the rear ends of the Ironing surface ensure perfect and gentle ironing. The rounded one Completion of the sliding surface, however, creates a steep slope in relation to the sliding surface Rise from the sliding surface to the housing, which prevents tight spaces from satisfactory can be ironed. In addition, when the sole is bent, the tip is created and grooves and folds at the rear corners of the metal sole, as the edge area is strongly compressed at the top and corners. Caught in the chords often folds or buttons, so that there is damage to the ironing.

Die Riefen und Auffaltungen können gemäß eines zweiten Verfahrens vermieden werden, wenn in den Spitzen der Metallsohle ein noch steilerer Anstieg des Kantenbereiches gewählt wird, so daß das Material des Kantenbereiches beim Auffalten nicht so stark komprimiert wird. Der Radius der Gleitfläche beim Bügeln beengeter Stellen wird aber durch den steileren Kantenbereich noch wesentlich weiter eingeschränkt. Das Bügeln beengter Stellen wie Knopfleisten, Spitzen und Rüschen gestaltet sich somit sehr schwierig.The striations and folds can be avoided according to a second method, if there is an even steeper increase in the edge area in the tips of the metal sole is chosen so that the material of the edge area is not so strong when unfolded is compressed. The radius of the sliding surface when ironing tight spaces is however further restricted by the steeper edge area. The ironing confined spaces such as button placket, laces and ruffles are very attractive difficult.

Es ist daher Aufgabe der Erfindung, ein Bügeleisen mit einer Metallsohle bereitzustellen, die ein verbessertes Bügeln beengter Stellen gewährleistet.It is therefore an object of the invention to provide an iron with a metal sole, which ensures improved ironing of tight spaces.

Diese Aufgabe wird durch ein Bügeleisen mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.This task is carried out by an iron with the characteristic features of the Claim 1 solved.

Bei einem Bügeleisen nach dem Anspruch 1 ist die Reichweite der Gleitfäche besonders groß, da der Kantenbereich einen auf maximal 35° begrenzten, besonders flachen Verlauf aufweist. Dieser flache Verlauf des Kantenbereichs ist jedoch nicht mit dem üblichen Nachteil der starken Stauchung des Materials der Metallsohle verbunden. Diese Stauchung des Materials wird dadurch vorteilhaft vermieden oder verringert, daß im Kantenbereich jeweils an den Ecken der Gleitfläche ein Ausschnitt eingearbeitet ist. Die den Ausschnitt begrenzenden Kanten grenzen nach dem Biegen unmittelbar aneinander an, so daß die nach außen weisende Oberfläche des Kantenbereichs weitgehend glatt und riefenfrei ist. Durch das Vermeiden oder Verringern der Stauchung ergibt sich weiter vorteilhaft, daß der flache Winkel des Kantenbereichs auch in den Ecken der Gleitfläche eingehalten wird.In an iron according to claim 1, the range of the sliding surface is special large because the edge area is particularly flat, limited to a maximum of 35 ° Has history. However, this flat course of the edge area is not the same usual disadvantage of the strong compression of the material of the metal sole connected. This Compression of the material is advantageously avoided or reduced in that A cutout is worked into the edge area at the corners of the sliding surface. The Edges delimiting the cutout immediately adjoin one another after bending so that the outward-facing surface of the edge area is largely smooth and is streak-free. By avoiding or reducing the compression further results advantageous that the flat angle of the edge area also in the corners of the sliding surface is observed.

Das Bügeleisen nach Anspruch 2 weist dabei eine besonders glatte Oberfläche auf.The iron according to claim 2 has a particularly smooth surface.

Die erfindungsgemäße Metallsohle kann an den Spitzen der Gleitfläche minimale Radien aufweisen, da kein überstehendes Material zu komprimieren ist. Diese minimalen Radien erleichtern insbesondere das Durchführen schwieriger Bügelaufgaben wie das Bügeln von Spitzen, Rüschen und Knopfleisten.The metal sole according to the invention can have minimal radii at the tips of the sliding surface have, since no protruding material has to be compressed. These minimal radii make it easier to perform difficult ironing tasks such as ironing of laces, frills and button strips.

Der besonders flache Winkel zwischen Kantenbereich und Gleitfläche hat weiter den Vorteil, daß ein ästhetisch ansprechender Übergang zwischen Gehäuse und Metallsohle entsteht. Der bei steileren Winkeln entstehende Spalt, der zum Teil eine freie Sicht auf das Gehäuseinnere ermöglicht, ist auch aus sicherheitstechnischen Überlegungen heraus unerwünscht.The particularly flat angle between the edge area and the sliding surface also has that Advantage that an aesthetically pleasing transition between the housing and the metal sole arises. The gap that arises at steeper angles, some of which has a clear view of The interior of the housing is also possible due to safety considerations undesirable.

Die erfindungsgemäße Metallsohle kann nach Anspruch 3 und 4 sowohl aus Aluminium als auch aus Stahlblech gefertigt werden. Es ist überdies möglich, die Metallsohle zu beschichten. Die Beschichtung kann vor oder nach dem Formen der Metallsohle aufgetragen werden.The metal sole according to the invention can be made of aluminum according to claims 3 and 4 as well as made of sheet steel. It is also possible to close the metal sole coat. The coating can be applied before or after shaping the metal sole become.

Gemäß Anspruch 6 wird die erfindungsgemäße Sohle aus einem Zuschnitt hergestellt, der in einer oder in mehreren aufeinanderfolgenden Bearbeitungsvorrichtungen geformt wird. Der Zuschnitt weist eine Gleitfläche und einen an die Außenlinie der Gleitfläche angrenzenden Kantenbereich auf. Der Kantenbereich weist an mindestens einer Spitze einen Ausschnitt auf. In der Bearbeitungsvorrichtung, beispielsweise einer an sich bekannten Stufenpresse, wird der Kantenbereich des Zuschnitts in mindestens zwei aufeinanderfolgenden Bearbeitungsschritten, bezogen auf die Gleitfläche, bis auf einen Winkel von maximal 35° abgewinkelt. Dabei werden die den Ausschnitt begrenzenden Seitenkanten unmittelbar aneinandergefügt. Durch das erfindungsgemäße Verfahren wird eine besonders einfache und preiswerte Herstellung der Metallsohle ermöglicht.According to claim 6, the sole according to the invention is produced from a blank, formed in one or more successive processing devices becomes. The blank has a sliding surface and one on the outer line of the sliding surface adjacent edge area. The edge area has at least one tip a cutout. In the processing device, for example one per se known step press, the edge area of the blank is cut into at least two successive processing steps, based on the sliding surface, except for one Angled by a maximum of 35 °. This will limit the section Side edges joined together immediately. By the method according to the invention a particularly simple and inexpensive manufacture of the metal sole is made possible.

Durch das Verfahren nach Anspruch 6 und insbesondere das Vorsehen der Ausschnitte werden in vorteilhafter Weise die auftretenden Materialverdickungen im Bereich der spitzen Winkel der Außenlinie der Gleitfläche vermieden. Dadurch ist es möglich, den Kantenbereich der Bügeleisensohle in einen spitzeren Winkel umzubiegen und somit, wie gemäß Anpruch 1 ausgeführt, die Reichweite der Gleitfläche des Bügeleisens zu vergrößern.By the method according to claim 6 and in particular the provision of the cutouts the material thickening in the area of the avoided acute angle of the outer line of the sliding surface. This makes it possible to Edge area of the soleplate to bend to a more acute angle and thus how executed according to claim 1 to increase the range of the sliding surface of the iron.

Bei dem Verfahren nach Anspruch 7 wird dabei in vorteilhafter Weise die Materialverdickung im Bereich der spitzen Winkel beim Umbiegen des Kantenbereiches gänzlich vermieden. Durch eine entsprechende Nachbehandlung des Spaltes können die Seitenkanten ineinander fließen, so daß sich eine glatte Oberfläche ergibt.In the method according to claim 7, the material thickening is advantageous in the area of the acute angles when bending the edge area entirely avoided. The side edges can be treated accordingly flow into each other so that there is a smooth surface.

In weiterer vorteilhaften Ausgestaltung des Verfahrens gemäß Anpruch 8 erstreckt sich der Ausschnitt nicht vollständig bis zur Außenlinie der Gleitfläche. Es kommt dann zwar beim Umbiegen des Kantenbereiches dennoch zu Materialverdickungen; diese Materialverdickungen können jedoch durch geeignetes Bearbeiten wie z.B. Hämmern oder Dengeln in den Bereich des Ausschnittes hineingetrieben werden. Dadurch können die auftretenden Materialverdickungen mit geringem Aufwand beseitigt werden, indem ein Teil dieses Materiales in den Spalt hineinfließt. Es entsteht hierbei dann eine glatte Oberfläche.In a further advantageous embodiment of the method according to claim 8 extends the cut-out is not completely up to the outline of the sliding surface. Then it comes when bending the edge area to material thickening; these thickened materials However, by suitable processing such as Hammering or To be driven into the area of the cutout. This allows the occurring material thickening can be eliminated with little effort by a Part of this material flows into the gap. The result is a smooth one Surface.

Gemäß einem weiter bevorzugten Verfahren nach Anspruch 9 wird der Zuschnitt nach dem Formen weiter bearbeitet. Der Spalt, der durch die aneinandergrenzenden Seitenkanten des Ausschnitts an den Spitzen der Metallsohle gebildet wird, wird nach dem Abwinkeln des Kantenbereichs so bearbeitet, daß die Seitenkanten zusammenfließen. Dadurch entsteht eine vollständig geschlossene äußere Oberfläche des Kantenbereiches.According to a further preferred method according to claim 9, the blank is made according to worked on the shaping. The gap created by the contiguous side edges of the cutout at the tips of the metal sole is made after the Edging the edge area processed so that the side edges flow together. This creates a completely closed outer surface of the edge area.

Nachfolgend wird die erfindungsgemäße Metallsohle an einem Ausführungsbeispiel näher erläutert.The metal sole according to the invention is illustrated below using an exemplary embodiment explained in more detail.

Fig. 1 zeigt eine Metallsohle 2 aus Aluminium, die eine in etwa dreieckige Form aufweist. Die Sohle 2 besteht aus einer Gleitfläche 4 und einem Kantenbereich 6.Der Kantenbereich 6 umgibt die Gleitfläche 4 vollständig und überdeckt den äußeren Bereich der Gleitfläche 4 teilweise. an den Spitzen "S" weist der Kantenbereich jeweils einen Spalt 8 auf, der allerdings durch ein Nachbearbeiten nach dem Formen der Sohle an der äußeren Oberfläche des Kantenbereichs 6 nicht sichtbar ist.Fig. 1 shows a metal sole 2 made of aluminum, which has an approximately triangular shape. The sole 2 consists of a sliding surface 4 and an edge region 6 Edge area 6 completely surrounds the sliding surface 4 and covers the outer area the sliding surface 4 partially. at the tips "S" the edge area has one Gap 8, which, however, by reworking after shaping the sole on the outer surface of the edge region 6 is not visible.

Fig. 2 zeigt ein Bügeleisen 10 mit einem Gehäuse 12, in dem Mittel zum Beheizen der Gleitfläche 4 angeordnet sind. Die Mittel 14 (in Fig. 2 gestrichelt angedeutet) sind hier als Aluminium-Heizblock ausgeführt, der zusätzlich auf der Metallsohle verklebt ist. Das Bügeleisen kann ein einfaches elektrisches Bügeleisen, aber auch ein Dampfbügeleisen sein. Aus Fig. 2 ist ersichtlich, daß der Kantenbereich 6, bezogen auf die Gleitfläche 4 in einem Winkel abgewinkelt ist. Der Winkel α ist bevorzugt kleiner als 30, jedenfalls nicht größer als 35.Fig. 2 shows an iron 10 with a housing 12, in the means for heating the Sliding surface 4 are arranged. The means 14 (indicated by dashed lines in FIG. 2) are here designed as an aluminum heating block, which is additionally glued to the metal sole. The Iron can be a simple electric iron, but also a steam iron be. From Fig. 2 it can be seen that the edge region 6, based on the sliding surface 4th is angled at an angle. The angle α is preferably less than 30, in any case not larger than 35.

In Fig. 3 ist ein Zuschnitt 16 für eine Metallsohle 2 dargestellt. Er weist einen in etwa dreieckigen Grundriß auf. An die Außenlinie 18 der Gleitfläche 4 schließt sich der Kantenbereich 6 an. An den Spitzen S des Zuschnitts ist jeweils ein ungefähr dreieckiger Ausschnitt 20 eingearbeitet. Eine Spitze des Ausschnitts 20 erstreckt sich bis an die Außenlinie 18, eine Grundlinie 24 fällt in etwa mit der Außenkante 26 des Kantenbereichs 6 zusammen. Die Seitenkanten 28 des Ausschnitts 20 bilden bei der fertigen Sohle 2 den Spalt 8 (siehe Fig. 1). Der Winkel, in dem die beiden Seitenkanten 28 zueinander stehen, wird durch den Winkel α bestimmt. Je flacher der Winkel α , desto größer der Winkel zwischen den Kanten 28.3 shows a blank 16 for a metal sole 2. He has one triangular floor plan. At the outer line 18 of the sliding surface 4, the Edge area 6. At the tips S of the blank there is an approximately triangular one Cutout 20 incorporated. A tip of the cutout 20 extends to the Outer line 18, a base line 24 coincides approximately with the outer edge 26 of the edge region 6 together. The side edges 28 of the cutout 20 form in the finished Sole 2 the gap 8 (see Fig. 1). The angle at which the two side edges 28 to each other is determined by the angle α. The flatter the angle α, the more greater the angle between the edges 28.

Die erfindungsgemäße Metallsohle wird aus dem in Fig. 3 dargestellten Zuschnitt hergestellt, indem zunächst die Ausschnitte 20 ausgestanzt werden. Dann wird der Kantenbereich 6 umlaufend um die Gleitfläche 4 in einer Stufenpresse in mehreren, aufeinanderfolgenden Schritten abgewinkelt, so wie dies schematisch in Fig. 4 dargestellt ist. Nach der letzten Stufe steht der Kantenbereich 6 in einem Winkel von ca. 30 zur Gleitfläche 4 und die Seitenkanten 28 des Ausschnitts 20 bilden den Spalt 8. Im Anschluß an das Abwinkeln des Kantenbereichs 6 werden die Spalte 8 mechanisch nachbearbeitet, so daß auf der äußeren Oberfläche des Kantenbereichs 8 die Seitenkanten 28 zusammenfließen, damit kein Spalt mehr sichtbar ist. Diese mechanische Bearbeitung kann beispielsweise durch plastische Verformung wie z.B. Hämmern oder Dengeln erfolgen. Durch dieses Verfahren wird eine Metallsohle für ein Bügeleisen hergestellt, dessen Kantenbereich 6 bezogen auf die Gleitfläche 4 auf ca. 30 abgewinkelt ist, und wobei die äußere Oberfläche des Kantenbereichs 6 vollständig glatt und eben ist.The metal sole according to the invention is made from the blank shown in FIG. 3 produced by first punching out the cutouts 20. Then the Edge area 6 all around the sliding surface 4 in a step press in several, successive steps angled, as shown schematically in Fig. 4 is. After the last step, the edge area 6 is at an angle of approx. 30 to the sliding surface 4 and the side edges 28 of the cutout 20 form the gap 8. Im Following the angling of the edge area 6, the gaps 8 become mechanical post-processed so that the side edges on the outer surface of the edge region 8 28 flow together so that no gap is visible. This mechanical processing can, for example, by plastic deformation such as Hammering or To be done. This process creates a metal soleplate for an iron produced, the edge area 6 angled relative to the sliding surface 4 to about 30 , and wherein the outer surface of the edge region 6 is completely smooth and is.

Vorteilhaft kommt dabei die Sohle 2 mit einem (nicht dargestellten) Bügeleisenschuh derart in Kontakt, daß sowohl die Gleitfläche 4 als auch der Kantenbereich 6 eine wärmeleitende Verbindung mit dem Bügeleisenschuh aufweist.The sole 2 advantageously comes with an iron shoe (not shown) in contact so that both the sliding surface 4 and the edge region 6 a has heat-conducting connection with the iron shoe.

Fig. 5 zeigt eine Aufsicht auf einen anderen Zuschnitt. In Fig. 5 zeigt sich im Unterschied zur Fig. 3, daß die sich an den Spitzen S befindenden Ausschnitte 20 sich nicht bis an die Außenlinie 18 der Gleitfläche 4 erstrecken. Beim Umbiegen des Kantenbereiches 6 kommt es dabei an den Spitzen S wiederum zu den Materialverdickungen. Diese Materialverdickungen sind dabei jedoch weniger stark ausgeprägt als wenn keine Ausschnitte 20 vorhanden wären. Durch eine entsprechende mechanische Bearbeitung wie beispielsweise Hämmern oder Dengeln ist es weiterhin möglich, diese Materialverdickungen derart zu behandeln, daß das Material in den entstehenden Spalt 8 gemäß Fig. 6 hineinfließt. Dadurch, daß ein Teil des wegen der Materialverdickung überflüssigen Materiales in den Spalt 8 hineinfließen kann, ist es möglich, im Kantenbereich wiederum eine glatte Oberfläche an der Außenseite zu erhalten. Gegenüber dem Ausführungsbeispiel nach den Fig. 3 und 1 zeigt sich bei dem Ausführungsbeispiel nach den Fig. 5 und 6, daß gerade im Bereich der Außenlinie der Gleitfläche im unmittelbaren Bereich der Spitze kein Spalt auftritt und daß somit dort die äußere Oberfläche besonders glatt und ohne Riefen ausgebildet ist.5 shows a top view of another blank. 5 shows the difference 3 that the cutouts 20 located at the tips S are not extend to the outer line 18 of the sliding surface 4. When bending the edge area 6, material thickening occurs at the tips S. However, these thickened materials are less pronounced than if none Cutouts 20 would be available. By appropriate mechanical processing such as hammers or thorns, it is still possible to thicken these materials to be treated such that the material in the resulting gap 8 according Fig. 6 flows into it. Because part of the superfluous because of the material thickening Material can flow into the gap 8, it is possible in the edge area again to get a smooth surface on the outside. Compared to the embodiment 3 and 1 shows in the embodiment of the 5 and 6 that just in the area of the outline of the sliding surface in the immediate vicinity No gap occurs in the area of the tip and therefore the outer surface there is special is smooth and without grooves.
