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. 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 connected to the means for heating, usually a good heat-conducting metal shoe, for example made of cast aluminum. A positive connection between the metal sole and the metal shoe is achieved according to a first method in that a blank of the metal sole is placed under the metal shoe and then bent over the shoe. This creates a rounded end of the sliding surface. With the usually approximately triangular ironing surface, the front tip of which is used to iron 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 . However, the rounded end of the sliding surface creates, with respect to the sliding surface, a steep rise from the sliding surface to the housing, which prevents tight spaces from being ironed satisfactorily. In addition, when the sole is bent, grooves and folds are created at the tip and at the rear corners of the metal sole, since the edge area at the tip and corners is strongly compressed. Wrinkles or buttons often get caught in the grooves, so that the ironing material is damaged.

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 scoring and unfolding can be avoided according to a second method if an even steeper increase in the edge area is selected in the tips of the metal sole, so that the material of the edge area is not compressed so much when unfolding. The radius of the sliding surface when ironing tight spaces is, however, further restricted by the steeper edge area. It is very difficult to iron tight spaces such as button strips, laces and ruffles.

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 confined 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 particularly large, since the edge region has a particularly flat course limited to a maximum of 35 °. However, this flat course of the edge region is not associated with the usual disadvantage of the strong compression of the material of the metal sole. This compression of the material is advantageously avoided or reduced in that a cutout is incorporated in the edge region in each case 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 region is largely smooth and free of grooves. By avoiding or reducing the compression, it is also advantageous that the flat angle of the edge area is also maintained in the corners of the sliding surface.

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, since no protruding material has to be compressed. These minimal radii make it easier to carry out difficult ironing tasks such as ironing lace, 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 has the further advantage that an aesthetically pleasing transition between the housing and the metal sole is created. The gap that arises at steeper angles, which in some cases allows a clear view of the interior of the housing, is also undesirable for safety reasons.

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 according to claims 3 and 4 both from aluminum and from sheet steel. It is also possible to coat the metal sole. The coating can be applied before or after the metal sole is formed.

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. The blank has a sliding surface and an edge region adjoining the outer line of the sliding surface. The edge area has a cutout on at least one tip. In the processing device, for example a step press known per se, the edge region of the blank is angled to an angle of at most 35 ° in at least two successive processing steps, based on the sliding surface. The side edges delimiting the cutout are directly joined together. The inventive method enables a particularly simple and inexpensive manufacture of the metal sole.

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.The method according to claim 6 and in particular the provision of the cutouts advantageously avoid the thickening of the material occurring in the area of the acute angles of the outer line of the sliding surface. This makes it possible to bend the edge area of the soleplate to a more acute angle and thus, as stated in 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 in the region of the acute angles when bending the edge region is completely avoided in an advantageous manner. Appropriate post-treatment of the gap allows the side edges to flow into one another, resulting in 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, the cutout does not extend completely to the outer line of the sliding surface. Though there is a thickening of the material when bending the edge area; these material thickenings can, however, be processed by suitable processing such as Hammering or peening into the area of the cutout. As a result, the material thickening that occurs can be eliminated with little effort, in that part of this material flows into the gap. This creates a smooth 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 further processed after the shaping. The gap created by the contiguous side edges of the cutout is formed at the tips of the metal sole, is machined after the angled edge area 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 explained in more detail below using an exemplary embodiment.

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. The edge region 6 completely surrounds the sliding surface 4 and partially covers the outer region of the sliding surface 4. at the tips "S" the edge area each has a gap 8, which, however, is not visible on the outer surface of the edge area 6 due to reworking after shaping the sole.

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 which means for heating the sliding surface 4 are arranged. The means 14 (indicated by dashed lines in FIG. 2) are designed here as an aluminum heating block, which is additionally glued to the metal sole. The iron can be a simple electric iron, but it can also be a steam iron. From Fig. 2 it can be seen that the edge region 6 is angled at an angle with respect to the sliding surface 4. The angle α is preferably less than 30, in any case not greater 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. It has an approximately triangular layout. At the outer line 18 of the sliding surface 4, the Edge area 6. An approximately triangular cutout 20 is incorporated in each case at the tips S of the blank. 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. The side edges 28 of the cutout 20 form the gap 8 in the finished sole 2 (see FIG. 1). The angle at which the two side edges 28 are in relation to one another is determined by the angle α. The flatter the angle α, the 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 produced from the blank shown in FIG. 3 by first punching out the cutouts 20. Then the edge region 6 is angled all around the sliding surface 4 in a step press in several successive steps, as is shown schematically in FIG. 4. After the last step, the edge area 6 is at an angle of approximately 30 to the sliding surface 4 and the side edges 28 of the cutout 20 form the gap 8. Following the angling of the edge area 6, the column 8 are mechanically reworked, so that on the outer Surface of the edge area 8, the side edges 28 flow together so that no gap is visible. This mechanical processing can, for example, by plastic deformation such as Hammering or banging. This method produces a metal soleplate for an iron, the edge area 6 of which is angled to approximately 30 in relation to the sliding surface 4, and the outer surface of the edge area 6 is completely smooth and flat.

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.Advantageously, the sole 2 comes into contact with an iron shoe (not shown) in such a way that both the sliding surface 4 and the edge region 6 have a 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, in contrast to FIG. 3, that the cutouts 20 located at the tips S do not extend to the outer line 18 of the sliding surface 4. When the edge region 6 is bent over, the material S becomes thickened again at the tips S. However, these material thickenings are less pronounced than if there were no cutouts 20. By appropriate mechanical processing such as hammers or thorns, it is also possible to treat these thickened materials in such a way that the material flows into the resulting gap 8 according to FIG. 6. Because part of the material which is superfluous because of the thickening of the material can flow into the gap 8, it is possible to obtain a smooth surface on the outside in the edge area. Compared to the embodiment according to FIGS. 3 and 1, it is shown in the embodiment according to FIGS. 5 and 6 that precisely in the area of the outer line of the sliding surface in the immediate area of the tip there is no gap and that there the outer surface there is particularly smooth and without Scoring is formed.
