Abstract

The spur bracket consists of a U-shaped bracket part and the spur (22). The bracket part consists of a base (24) with the spur on it and side arms (26). The bracket part is stamped, so that the arms have a profile deviating from the rectangular cross section of the cutout, in particular, they have a bulge on their outer surface, projecting outwards or inwards.

Description

Die Erfindung bezieht sich auf einen Sporenbügel nach dem Oberbegriff des Anspruchs 1 und auf ein Verfahren zur Herstellung eines Sporenbügels.The invention relates to a Sporenbügel according to the preamble of claim 1 and to a method for producing a Sporenbügels.

Ein derartiger Sporenbügel ist aus GB 17 481 A bekannt. Dieser vorbekannte Sporenbügel ist wie folgt hergestellt: Zur Herstellung eines Sporenbügels werden von einem stabförmigen Profilmaterial mit D-Profil zwei Zuschnitte abgeschnitten. Diese Zuschnitte werden nun gebogen. Dabei wird jedem Zuschnitt die Form eines halben U mit daran einstückig angesetztem, halbem Sporenarm mitgegeben. Ein fertig gebogener Zuschnitt ist in Figur 1 von GB 17 481 A dargestellt. Anschließend werden die beiden gebogenen Zuschnitte zusammengefügt, dabei werden sie zwischen den beiden halben Sporenarmen verbunden und es wird zwischen ihnen eine Achse und ein Sporenrädchen angeordnet.Such a Sporenbügel is known from GB 17 481 A. This known Sporenbügel is made as follows: To produce a spur strap two blanks are cut from a rod-shaped profile material with D-profile. These blanks are now bent. Each blank is given the shape of a half U with it integrally attached, half Sporenarm. A finished bent blank is shown in Figure 1 of GB 17481A. Then, the two bent blanks are joined, they are connected between the two half spore arms and it is arranged between them an axis and a spur wheel.

Die Bügelteile von Sporenbügeln werden alternativ auch einstückig im Gussverfahren hergestellt, zumeist wird dann auch gleich der Sporen einstückig beim Gießen mit hergestellt. Gegossene Bügelteile bzw. Sporenbügel haben eine ansprechende, gerundete Außenfläche, die nicht nur eine Höherwertigkeit signalisiert, sondern auch optisch ein gutes Bild abgibt. Gegossene Sporenbügel haben üblicherweise einen unregelmäßigen Querschnitt, sie sind im Mittelbereich der Schenkel dicker als am oberen oder unteren Rand der Schenkel. Diese Materialdicke führt zu einer spürbaren Festigkeit und Steifigkeit des U-förmigen Bügelteils. Nun sind aber gegossene Sporenbügel in ihrer Herstellung relativ teuer, sie erfordern vorrichtungsmäßig wie auch handwerklich einen relativ großen Aufwand für ihre Herstellung.The temple parts of Sporenbügeln are alternatively also made in one piece by casting, usually then equal to the spores is made in one piece during casting. Cast iron or Sporenbügel have an attractive, rounded outer surface, which not only signals a high quality, but also visually gives a good picture. Cast spur bars usually have an irregular cross-section, they are thicker in the middle region of the legs than at the top or bottom of the legs. This material thickness leads to a noticeable strength and rigidity of the U-shaped bracket part. Now, however, cast spur bars are relatively expensive to produce, requiring a relatively large amount of device-related effort both in terms of equipment and craftsmanship.

Es sind auch Sporenbügel bekannt, die wie folgt hergestellt werden: Zunächst wird ein länglicher Zuschnitt aus Blech ausgestanzt, dann gebogen, so dass das U-förmige Bügelteil gebildet wird, schließlich wird der Sporen an der Außenseite der Basis des Bügelteils angebracht. Derartige Sporenbügel haben jedoch einen flachen Querschnitt ihrer Schenkel. Dieser wirkt sich optisch aus, aufgrund der flachen Schenkel ihrer Bügelteile sie sind klar zu unterscheiden von gegossenen Sporenbügeln. Ihre Außenfläche ist glatt und eben. Sie sind auch nicht so widerstandsfähig gegen ein Verbiegen wie gegossene Sporenbügel.Sporenbügel are also known, which are manufactured as follows: First an elongated blank punched out of sheet metal, then bent so that the U-shaped bracket part is formed, finally, the spore is attached to the outside of the base of the bracket part. However, such Sporenbügel have a flat cross-section of their legs. This has a visual effect, due to the flat legs of their temple parts they are clearly distinguishable from cast spurs. Its outer surface is smooth and even. They are not as resistant to bending as cast spur bars.

Hier setzt nun die Erfindung ein. Sie hat es sich zur Aufgabe gemacht, den Sporenbügel der eingangs genannten Art so weiter zu entwickeln, dass durch einfache, zusätzliche Bearbeitungsschritte der Sporenbügel ein Aussehen erhält, das ihn möglichst wenig von gegossenen Sporenbügeln unterscheidet, wobei die einfache und kostengünstige Herstellungsweise des Sporenbügels der eingangs genannten Art beibehalten werden soll.This is where the invention begins. It has set itself the task of further developing the Sporenbügel of the type mentioned above, that by simple additional processing steps of Sporenbügel receives an appearance that distinguishes him as little as possible from cast Sporenbügeln, the simple and cost-effective production of the Sporenbügels the to be maintained.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 9 gelöst.This object is solved by the features of claims 1 and 9.

Bei diesem Sporenbügel ist die Tatsache, dass er aus Metallblech hergestellt ist, von außen, insbesondere wenn er an einem Reitstiefel getragen wird, nur noch sehr schwer zu erkennen. Die seitlichen Schenkel haben an ihrer Außenfläche eine nach außen vorstehende Wölbung, die genauso geformt und ausgebildet sein soll und kann, wie sie bei den gegossenen Sporenbügeln geformt ist. Wenn der erfindungsgemäße Sporenbügel auf einen Reitstiefel aufgesetzt ist, erkennt man die zwangsläufig an der Innenfläche des Bügelteils notwendige Einwölbung nicht.In this spur bar, the fact that it is made of sheet metal, from the outside, especially if it is worn on a riding boot, is very difficult to recognize. The lateral legs have on their outer surface an outwardly projecting curvature, which should be just as shaped and formed and can, as it is formed in the cast Sporenbügeln. If the Sporenbügel invention is placed on a riding boot, you can see the inevitably necessary on the inner surface of the bracket part indentation.

Durch die erfindungsgemäße Veränderung bzw. Verformung des Querschnitts des Bügelteils, insbesondere seiner beiden Schenkel, wird auch eine Erhöhung der Steifigkeit erzielt. Im Zusammenwirken mit dem gewählten Blechmaterial und dessen Materialstärke wird eine für die Praxis sehr geeignete Steifigkeit des Bügelteils erreicht. Dieses kann zwar immer noch gebogen werden, also einem Stiefelschaft angepaßt werden, ein derartiges Biegen erfordert aber eine viel höhere Kraft und die gelegentlich kritisierte Weichheit gegen Verbiegen der Sporenbügel der eingangs Art ist nun nicht mehr gegeben. In der Praxis zeigt sich, dass sich die erfindungsgemäßen Sporenbügel gezielt verbiegen lassen, aufgrund ihrer Steifigkeit aber dann im praktischen Einsatz die einmal verliehene Biegung beibehalten. Dies ist günstig.The inventive change or deformation of the cross section of the bracket part, in particular its two legs, an increase in the rigidity is achieved. In cooperation with the selected sheet metal material and its material strength is achieved for the practice very suitable stiffness of the bracket part. This can still be bent, so be adapted to a boot leg, but such bending requires a much higher power and the occasionally criticized softness against bending of the spurs of the type mentioned is no longer given. In practice, it turns out that the spur bars according to the invention can be bent specifically, but because of their rigidity but then in practical use, the once awarded bend maintained. This is cheap.

Bei der Herstellung wird also nach wie vor ein Zuschnitt aus Metallblech erstellt, der relativ länglich ist. An seinen beiden freien Enden hat er Befestigungsmittel für den Sporenbügel, beispielsweise Riemenösen. Im Bereich der Riemenösen und damit im Bereich der freien Enden hat der Zuschnitt vorzugsweise Verbreiterungen bzw. Erweiterungsbereiche, um Platz für die Riemenösen zu schaffen.During production, a blank made of sheet metal is still created, which is relatively elongated. At its two free ends it has attachment means for the spur stirrup, for example, strap eyelets. In the area of the belt eyelets and thus in the region of the free ends, the blank preferably has widenings or expansion areas in order to make room for the strap eyelets.

Im nächsten Schritt der Herstellung wird dieser Zuschnitt geprägt, indem mindestens eine Sicke auf der Innenfläche des Sporenbügels eingeprägt wird. Erst anschließend wird der Sporenbügel in seine U-Form gebogen.In the next step of the production of this blank is embossed by at least one bead is embossed on the inner surface of the spine strap. Only then is the spur bar bent into its U shape.

Die Sicke kann sich nun einstückig beginnend von dem Erweiterungsbereich an einem freien Ende hin zum Erweiterungsbereich am anderen freien Ende erstrecken. Es kann aber auch vorzugsweise in jedem Schenkel eine eigene Sicke ausgebildet sein, die im Bereich der Basis endet, so dass die Basis ungeprägt ist, also ihren rechteckförmigen Querschnitt beibehält. Dies hat den Vorteil, dass die Außenfläche der Basis geradlinig bleibt, so dass dort der Sporen besser angesetzt werden kann.The bead can now extend in one piece starting from the extension region at a free end to the extension region at the other free end. However, it is also preferable for each leg to have its own bead, which ends in the region of the base, so that the base is unembossed, that is, it retains its rectangular cross-section. This has the advantage that the outer surface of the base remains straight, so that there spores can be better recognized.

Üblicherweise sind die Erweiterungsbereiche, in denen sich die Riemenösen befinden, nicht geprägt. Es ist aber durchaus vorteilhaft, die Sicke auch bis in diese Bereiche durchlaufen zu lassen, was bei zwei nebeneinanderliegenden Riemenösen den Vorteil bietet, dass ein mittlerer Steg zwischen den beiden Riemenösen nach außen geprägt wird, was wiederum das Einfädeln eines Riemens erleichtert.Usually, the expansion areas in which the strap eyelets are not marked. However, it is quite advantageous to allow the bead to run through to these areas, which has the advantage in two juxtaposed strap eyelets that a central web between the two strap eyelets is stamped outward, which in turn facilitates the threading of a belt.

Bei dem Prägevorgang werden vorteilhafterweise die beim Zuschnitt normalerweise scharfen Ränder gerundet. Dadurch erspart man sich zusätzliche Bearbeitungsschritte, um die Ränder zu glätten. Dennoch ist es nicht ausgeschlossen, die Ränder auch anderweitig zu bearbeiten, beispielsweise durch Schleifen und Polieren.During the embossing process, the edges which are normally sharp when cutting are advantageously rounded. This saves additional processing steps to smooth the edges. Nevertheless, it is not excluded, the edges also edit elsewhere, for example, by grinding and polishing.

Als sehr bevorzugt hat es sich herausgestellt, an der vorzugsweise ungeprägten Basis einen nach außen vorstehenden Schweißbuckel vorzusehen, der dazu dient, mittels Buckelschweißen einen Sporen zu befestigen.As very preferred, it has been found to provide on the preferably unembossed base an outwardly projecting weld hump, which serves to fasten a spore by projection welding.

Die formmäßige Ausbildung der Wölbung an der Außenfläche zumindest der Schenkel ist beliebig. Die Wölbung kann auch an unterschiedlichen Stellen der Schenkel unterschiedlich ausgebildet sein. Die Wölbung wird so ausgeführt, dass ein möglichst gutes ästhetisches Gesamtbild erzielt wird. Im allgemeinen ist daher die Wölbung möglichst glatt und fließend, was jedoch nicht ausschließt, dass besondere lokale Merkmale ausgeprägt werden, wie beispielsweise Vorsprünge, Sterne usw., dies insbesondere für Reiter, die derartige hervorstechende Merkmale schätzen, beispielsweise Westernreiter. Nach wie vor hat der Zuschnitt für das Bügelteil die Form, die weitgehend das spätere Aussehen des Sporenbügels bestimmt. So ist es möglich, das im Anschluß an die Erweiterungsbereiche, in denen sich die Riemenösen befinden, die Schenkel eine relativ geringe Höhe haben und sich nach hinten, zur Basis hin, in ihrer Höhe steigern. Der Zuschnitt kann aber auch eine beliebige Form haben, beispielsweise zackige Ränder usw..The shape of the curvature on the outer surface of at least the legs is arbitrary. The curvature can also be formed differently at different locations of the legs. The curvature is carried out in such a way that the best possible overall aesthetic appearance is achieved. In general, therefore, the curvature is as smooth and fluid as possible, but this does not rule out that special local features are pronounced, such as projections, stars, etc., especially for riders who appreciate such salient features, such as Western riders. As before, the blank for the temple part has the shape that largely determines the later appearance of the spine strap. Thus, it is possible, in addition to the extension areas in which the strap loops are located, the legs have a relatively small height and increase towards the rear, towards the base, in their height. The blank can also have any shape, such as jagged edges etc ..

Der Sporenbügel hat in bekannter Weise ein U-förmiges Bügelteil 20 und einen Sporen 22. Letzterer kann lösbar oder permanent mit dem Bügelteil 20 verbunden sein. Das Bügelteil 20 hat eine relativ kurze Basis 24 und zwei von dieser zu beiden Seiten ausgehende Schenkel 26, die im wesentlichen baugleich sind. An der Basis 24 ist der Sporen 22 befestigt. Im bevorzugter Ausführung ist hierzu ein Buckel 28 vorgesehen, der nach außen, zum zu befestigenden Sporen 22 hin vorsteht.The Sporenbügel has in a known manner a U-shaped bracket member 20 and a spurs 22. The Sporenbügel may be releasably or permanently connected to the bracket member 20. The bracket member 20 has a relatively short base 24 and two legs 26 extending therefrom on both sides, which are substantially identical in construction. At the base 24 of the spurs 22 is attached. In the preferred embodiment, for this purpose, a projection 28 is provided, which protrudes outwards to the spores 22 to be fastened.

Das Bügelteil 20 wird aus einem Zuschnitt gefertigt, der in Figur 1 teilweise dargestellt ist. Er ist klappsymmetrisch zu einer Symmetrielinie 30. Gestrichelt ist der Bereich angedeutet, auf dem später außen der Sporen 22 sitzt.The bracket 20 is made of a blank, which is partially shown in FIG. It is hinged symmetrically to a line of symmetry 30. Dashed is the area indicated on the later outside of the spurs 22 sits.

An den freien Enden des länglichen Zuschnitts befinden sich Verbreiterungen bzw. Erweiterungsbereiche 32, die jeweils etwa kopfförmig ausgebildet sind. In ihnen sind zwei zueinander parallele oder auch im Winkel zueinander verlaufende Langlöcher 34 als Ösen für einen Befestigungsgurt ausgebildet. Die Erweiterungsbereiche 32 gehören zu den Schenkeln 26.At the free ends of the elongate blank are widenings or extension regions 32, which are each formed approximately head-shaped. In them, two mutually parallel or at an angle to each other extending slots 34 are formed as eyelets for a fastening belt. The extension regions 32 belong to the legs 26.

Im Schenkel 26 ist eine Sicke 36 eingeprägt. Dadurch hat der Schenkel 26 an seiner Außenfläche eine nach außen vorstehende Wölbung 38. Wie Figur 1 zeigt, hat jeder Schenkel 26 seine eigene Sicke 36. Diese beginnt hinter dem Erweiterungsbereich 32 und endet vor der Basis 24. Die Basis 24 ist damit ungeprägt, siehe Figur 2, so dass auf ihr einfach der Sporen 22 befestigt werden kann. Grundsätzlich ist es auch möglich, die Sicke 36 durch die Basis 24 durchlaufen zu lassen, also nur eine einzige Sicke vorzusehen. In diesem Fall muß der Sporen 22 an seinem Ende, mit dem er auf der Basis 24 aufsitzt, an die dortige Wölbung 38 angepaßt werden. Letzteres ist bei einer nicht geprägten Basis 24 nicht erforderlich.In the leg 26 a bead 36 is embossed. As a result, the leg 26 has on its outer surface an outwardly protruding arch 38. As shown in FIG. 1, each leg 26 has its own bead 36. This begins behind the flared area 32 and ends in front of the base 24. The base 24 is thus unembossed, see FIG. 2, so that the spore 22 can simply be fastened to it. In principle, it is also possible to allow the bead 36 to pass through the base 24, ie to provide only a single bead. In this case, the spurs 22 must be adapted at its end, with which it rests on the base 24, to the local curvature 38. The latter is not necessary with an unembossed base 24.

Der Zuschnitt, wie er in Figur 1 dargestellt ist, ist aus einem Edelstahlblech von 2,5 mm Dicke durch Stanzen hergestellt. Dabei sind die Langlöcher 34 mit ausgebildet. In einem weiteren Arbeitsschritt wird dann dieser Zuschnitt geprägt, indem in die beiden Schenkel 26 jeweils eine Sicke 36 eingeprägt wird, dieser Zustand des Zuschnittes ist in Figur 1 gezeigt. Anschließend wird der nunmehr geprägte Zuschnitt in die U-Form gebogen, so dass der U-förmige Zustand gemäß Figur 2 vorliegt.The blank, as shown in Figure 1, is made of a stainless steel sheet of 2.5 mm thickness by punching. The slots 34 are formed with. In a further step, this blank is then embossed by embossing a bead 36 in each of the two legs 26, this state of the blank being shown in FIG. Subsequently, the now embossed blank is bent into the U-shape so that the U-shaped state according to FIG. 2 is present.

Aus den Figuren 3 bis 5 sind unterschiedliche Querschnittsformen der Schenkel 26 im Bereich der Schnittlinie III-III ersichtlich. Diese unterschiedlichen Querschnittsformen sollen nachweisen, dass man auf die konkrete Ausgestaltung der Sicke 36 relativ viel Einfluß hat, man kann also deutlich unterschiedliche Formen vorgeben, wie beispielsweise ein Vergleich der Figuren 3 und 5 zeigt. Im Ausführungsbeispiel nach Figur 5 ist eine Sicke lokal recht tief eingeprägt, während im Ausführungsbeispiel nach Figur 4 sich die Sicke über praktisch die gesamte Höhe des Profils erstreckt. Im Ausführungsbeispiel nach Figur 3 erstreckt sich die Sicke in ihrer Höhe nicht über die gesamte Höhe des Schenkels 26, es liegt also eine Ausbildung vor, die zwischen denjenigen der Figuren 4 und 5 anzusiedeln ist. Aus den drei dargestellten Querschnitten ist deutlich die Wölbung 38 an der Außenfläche der Schenkel 26 zu ersehen. Figur 4 zeigt, dass die Ränder gerundet sind, so dass keinerlei Kanten vorstehen. Dies kann auch bei den anderen Querschnittsformen so ausgebildet sein.FIGS. 3 to 5 show different cross-sectional shapes of the legs 26 in the region of the section line III-III. These different cross-sectional shapes should demonstrate that one has on the concrete configuration of the bead 36 relatively much influence, so you can specify significantly different shapes, such as a comparison of Figures 3 and 5 shows. In the embodiment of Figure 5, a bead is local deeply impressed, while in the embodiment of Figure 4, the bead extends over virtually the entire height of the profile. In the embodiment of Figure 3, the bead does not extend in height over the entire height of the leg 26, so there is a training, which is to be settled between those of Figures 4 and 5. The curvature 38 on the outer surface of the legs 26 can clearly be seen from the three cross sections shown. Figure 4 shows that the edges are rounded so that no edges protrude. This can also be formed in the other cross-sectional shapes.

Figur 6 schließlich zeigt eine Ausbildung, bei der die Prägung entlang der Mittellinie des Zuschnitts bis in den Bereich zwischen den beiden Langlöchern 34 durchgezogen ist. Dadurch ist der Steg, der sich zwischen den beiden Langlöchern 34 befindet, nach außen gedrückt. Auf diese Weise ist ein Einfädeln eines Gurtes oder eines Riemens vereinfacht, darüber hinaus liegt der Riemen besser, weil er nicht so stark abgekrümmt wird beim Durchlauf durch die beiden Langlöcher 34.Finally, FIG. 6 shows an embodiment in which the embossing is drawn through along the center line of the blank into the region between the two oblong holes. As a result, the web, which is located between the two slots 34, pushed outward. In this way, a threading of a belt or a belt is simplified, in addition, the belt is better because it is not bent so much when passing through the two slots 34.

Der fertige Sporenbügel ist elektropoliert. Das Prägen erfolgt in üblicher Weise mit einer Patrize und einer Matrize. Andere Verfahren, um die Sicke 36 auszubilden, sind damit nicht ausgeschlossen, beispielsweise kann die Sicke auch gerollt, eingedrückt usw. werden.The finished spur bar is electropolished.
