Description

Die Erfindung betrifft ein Harscheisen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a crampon according to the preamble of patent claim 1.

Harscheisen sind ein wichtiges Zubehör beim Tourengehen, das vor allem als Steighilfe für Aufstiege bei hartgefrorenem Schnee gedacht ist und insbesondere bei Schrägaufstiegen ein seitliches Abrutschen der Ski verhindern soll. Sie bestehen in der Regel aus einer Grundplatte und zwei von dieser ausgehenden seitlichen Führungsstegen, die in der Gebrauchslage des Harscheisens nach unten über die Lauffläche des Skis überstehen und in den Schnee eingreifen. Für die vorgesehene Funktionsweise des Harscheisens ist es wichtig, daß es am Ski selbst, an einem fest damit verbundenen Bauteil oder am Skistiefel sicheren Seitenhalt erfährt.Crampons are an important accessory when touring, which is primarily intended as a climbing aid for ascents in hard-frozen snow and is intended to prevent the skis from slipping sideways, particularly on inclined ascents. They usually consist of a base plate and two lateral guide webs extending from it, which in the use position of the crampon protrude down over the tread of the ski and engage in the snow. For the intended function of the crampon, it is important that it experiences secure lateral support on the ski itself, on a component connected to it, or on the ski boot.

Ein Beispiel für ein solches Harscheisen ist aus DE A 24 57 265 bekannt. Bei diesem Harscheisen ist die Grundplatte vorn und hinten mit Ausnehmungen versehen, und außerdem weist sie in etwa mittig eine im wesentlichen kreisrunde Öffnung auf. Zum Festhalten des Harscheisens sind auf der Oberseite des Skis und an der Unterseite der darauf montierten Tourenplatte wahlweise einsetzbare Befestigungsgarnituren angebracht, die jeweils aus einem Paar Sicherungslaschen und einer verdrehbaren Exzenterscheibe bestehen, die mit den stirnseitigen Ausnehmungen bzw. mit der mittigen Öffnung der Grundplatte zusammenwirken. Bei Benutzung der Befestigungsgarnitur auf dem Ski ist das Harscheisen fest mit diesem verbunden, während es bei Benutzung der Befestigungsgarnitur an der Tourenplatte deren Schwenkbewegung beim Gehen zu folgen vermag. Die Anbringung des bekannten Harscheisens setzt eine entsprechende Ausrüstung des Skis oder der Skibindung voraus, und außerdem ist es erforderlich, die verschiedenen Ausnehmungen und Öffnungen der Grundplatte genau in die Sicherungslaschen einzupassen bzw. mit der Exzenterscheibe zur Deckung zu bringen, was insbesondere im Tiefschnee und bei Vereisung von Ski und Bindung erhebliche Schwierigkeiten bereiten kann.An example of such a crampon is known from DE A 24 57 265. In this crampon, the base plate is provided with recesses at the front and rear, and moreover it has an essentially circular opening approximately in the center. To hold the crampon on the top of the ski and on the underside of the touring plate mounted on it, optionally usable fastening sets are attached, each consisting of a pair of securing straps and a rotatable eccentric disc, which interact with the front recesses or with the central opening of the base plate. When using the attachment set on the ski, the crampon is firmly connected to it, while when using the attachment set on the touring plate, it can follow its pivoting movement when walking. The attachment of the known crampon requires a suitable equipment of the ski or the ski binding, and it is also necessary to fit the various recesses and openings of the base plate exactly into the securing tabs or to cover them with the eccentric disc, especially in deep snow and in Icing of skis and bindings can cause considerable difficulties.

Überdies geht in letzter Zeit der Trend bei Tourenskibindungen dahin, die Tourenplatt möglichst zu verkleinern oder ganz wegzulassen und den Skistiefel nur im vorderen Sohlenbereich abzustützen, um Gewicht zu sparen. Durch den Wegfall der Tourenplatte entfällt jedoch zwangsläufig auch die Möglichkeit, das Harscheisen an der Tourenplatte zu verankern, um es Schwenkbewegungen des Skistiefels beim Gehen folgen zu lassen.In addition, the trend in touring ski bindings has recently been towards reducing the touring platform as much as possible or omitting it entirely and only supporting the ski boot in the front sole area in order to save weight. However, the omission of the touring plate inevitably means that the crampon cannot be anchored to the touring plate in order to allow swivel movements of the ski boot to follow when walking.

Zwar ist es aus DE A 28 17 422 bekannt, Harscheisen am Skistiefel festzulegen, doch sind dazu aufwendige Halterungen und ein langer Riemen erforderlich, mit dem das Harscheisen am Skistiefel festgeschnallt wird. Dies ergibt wiederum eine unerwünschte Gewichtserhöhung, und außerdem ist ein mit ösenartigen Halterungen und einem Riemen versehenes Harscheisen ein zusätzlicher sperriger Gegenstand, der beim Tourengehen unbequem mitzuführen ist.Although it is known from DE A 28 17 422 to fix crampons on the ski boot, complex brackets and a long strap are required to fasten the crampon to the ski boot. This, in turn, results in an undesirable increase in weight and, in addition, a crampon provided with eyelet-type holders and a strap is an additional bulky item which is inconvenient to carry when touring.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Harscheisen der eingangs erwähnten Art ohne größeren zusätzlichen Aufwand so auszubilden, daß es sich in einfacher und auch unter durch tiefen Schnee und Vereisung erschwerten Bedingungen stets zuverlässiger Weise auch an einer Skibindung ohne Tourenplatte oder Tourengestell befestigen läßt, ohne daß es dazu besonderer Vorkehrungen an der Skibindung oder am Ski bedarf.The invention is therefore based on the object of designing a crampon of the type mentioned at the outset without major additional effort so that it can always be reliably fastened to a ski binding without a touring plate or touring frame in a simple manner and also under conditions made more difficult by deep snow and icing, without special precautions on the ski binding or on the ski.

Die gestellte Aufgabe wird gemäß der Erfindung gelöst durch ein Harscheisen, wie es im Patentanspruch 1 angegeben ist; vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The object is achieved according to the invention by a crampon as specified in claim 1; advantageous developments and refinements of the invention result from the subclaims.

Durch die Halterung und Lagerung des Harscheisens an der vorderen Sohlenhaltevorrichtung erübrigt sich eine Befestigung des Harscheisens am Skistiefel, und es bedarf daher nach dem Lösen der Sohlenhaltevorrichtung nicht noch zusätzlich einer Abnahme des Harscheisens vom Skistiefel, wenn ein Tourengeher eine Rast einlegen will oder zum Überqueren einer kurzen felsigen Wegstrecke die Skier abschnallen muß. Außerdem macht diese Art der Lagerung an der vorderen Sohlenhaltevorrichtung zusätzliche Riemen zum Festhalten des Harscheisens am Skistiefel entbehrlich.Due to the mounting and storage of the crampon on the front sole holding device, there is no need to attach the crampon to the ski boot, and therefore, after the sole holding device has been released, there is no additional need for the crampon to be removed from the ski boot if a tourer wants to take a break or to cross one short rocky path the skis must unbuckle. In addition, this type of storage on the front sole holding device makes additional straps for holding the crampon on the ski boot unnecessary.

Dank der Ausstattung der Grundplatte mit einem einseitig darüber hinausragenden Ausleger ergibt sich eine konstruktiv einfache Ausführung für das Harscheisen insgesamt, und die auf der der Stütze der Sohlenhaltevorrichtung zugewandten Unterseite des Auslegers angeordnete Halteeinrichtung ermöglicht eine Anpassung an die Ausbildung der jeweils zugeordneten Stütze oder Schwenkachse.Thanks to the equipment of the base plate with a cantilever projecting on one side, there is a structurally simple design for the crampon as a whole, and the holding device arranged on the underside of the cantilever facing the support of the sole holding device enables adaptation to the design of the respectively assigned support or pivot axis.

Als vorteilhaft erweist sich außerdem, daß bei der Ausgestaltung des Harscheisens nach der Erfindung die Grundplatte am Lagerbock der vorderen Sohlenhaltevorrichtung angelenkt werden kann, wobei die Schwenkachse für das Harscheisen mit der für die den Skistiefel haltenden Stütze der Sohlenhaltevorrichtung überhaupt identisch ist oder wenigstens nahezu damit zusammenfällt, da auf diese Weise Relativbewegungen von Stiefelsohle und Harscheisen beim Gehen vermieden bleiben.It also proves to be advantageous that in the configuration of the crampon according to the invention the base plate can be articulated on the bearing block of the front sole holding device, the pivot axis for the crampon being at all identical or at least almost coinciding with that for the support of the sole holding device holding the ski boot , because this prevents relative movements of the boot sole and crampons when walking.

Für die Ausbildung der Halteeinrichtung selbst ist eine Ausführung als die Stütze auf einem Teil ihres Umfangs formschlüssig umgreifende Klemmfeder bevorzugt. Diese Ausführung ist zum einen selbst einfach herzustellen, und sie erleichtert zum anderen das Aufstecken des Harscheisens auf die Stütze.For the design of the holding device itself, an embodiment as a support spring which engages around the part in a form-fitting manner is preferred. On the one hand, this version is easy to manufacture and, on the other hand, it makes it easier to put the crampon on the support.

Die Herstellung des Harscheisens wird am einfachsten, wenn der Ausleger in einem Stück mit der Verlängerung der Grundplatte ausgebildet wird. Wenn jedoch in Weiterbildung der Erfindung der Ausleger lösbar mit der Grundplatte verbunden und außerdem eine Befestigungsmöglichkeit für den Ausleger an beiden Enden der Grundplatte vorgesehen wird, ergibt sich der zusätzliche Vorteil, daß das Harscheisen in zwei gegeneinader um 180° verdrehten Stellungen auf dem Ski befestigt werden kann.The easiest way to make the crampon is to form the boom in one piece with the extension of the base plate. However, if, in a further development of the invention, the boom is releasably connected to the base plate and, in addition, a fastening possibility for the boom is provided at both ends of the base plate, there is the additional advantage that the crampon is attached to the ski in two positions rotated by 180 ° relative to one another can.

Diese Möglichkeit ist besonders wünschenswert bei Ausführung der Führungsstege mit über ihre Länge unterschiedlicher Höhe, da sich dann durch unterschiedliche Anordnung des Harscheisens die Eindringtiefe in den Schnee variieren läßt. Dies erweist sich vor allem dann als günstig, wenn eine Steighilfe verwendet wird, die den Skistiefel mit Abstand von der Skioberfläche abstützt, was vor allem zum Bewältigen steiler Anstiege erwünscht ist. Bei Verwendung einer solchen Steighilfe kann es nämlich vorkommen, daß das Harscheisen nicht mehr hinreichend tief in den Schnee eingreift. Dem läßt sich dann dadurch abhelfen, daß das Harscheisen so auf dem Ski gewendet wird, daß sie üblicherweise am hinteren Ende befindlichen höheren Teile der Führungsstege das vordere Ende bilden, da dann auch bei angeschwenkter Stellung des Skistiefels unter dessen Abstützung durch die Steighilfe eine ausreichende Eindringtiefe der Führungssstege in den Schnee erhalten werden kann.This option is particularly desirable when the guide webs are designed with a different height over their length, since the depth of penetration into the snow can then be varied by arranging the crampon differently. This proves to be particularly advantageous if a climbing aid is used that supports the ski boot at a distance from the ski surface, which is particularly desirable for tackling steep climbs. When using such a climbing aid it can namely occur that the crampon no longer engages deep enough in the snow. This can then be remedied by turning the crampon on the ski in such a way that they usually form higher parts of the guide webs at the rear end, since the ski boot then has a sufficient depth of penetration even when the ski boot is in the pivoted position, supported by the climbing aid the walkways can be preserved in the snow.

Insbesondere bei verdrehbarer Halterung des Harscheisens auf der Stütze kann der Ausleger mit Vorteil in Form einer nach oben durchgebogenen Blattfeder ausgebildet werden, die das Harscheisen mit Vorspannung gegen den Skistiefel hält.In particular when the crampon is rotatably mounted on the support, the boom can advantageously be designed in the form of a leaf spring which is bent upwards and which holds the crampon against the ski boot with pretension.

Zur Unterstützung der Schwenkbewegung des Harscheisens beim Gehen ist es von Vorteil, den Ausleger gemäß einer Ausgestaltung der Erfindung mit einem vorderen Anschlag für die Stiefel spitze zu versehen.To support the pivoting movement of the crampon when walking, it is advantageous to tip the boom according to one embodiment of the invention with a front stop for the boots.

Nachstehend wird die Erfindung anhand bevorzugter Ausführungsbeispiele noch weiter erläutert; dabei zeigen in der Zeichnung:

Wie die Zeichnung zeigt, besteht ein Harscheisen, wie es insgesamt mit der Bezugszahl 1 bezeichnet ist, aus einer Grundplatte 2 und aus zwei seitlichen, nach unten vorstehenden Führungsstegen 3, die durch Ausnehmungen 4 in die Form je einer zusammenhängenden Reihe von Zähnen 5 gebracht sind. Die einzelnen Zähne 5 der Führungsstege 3 sind unterschiedlich lang ausgeführt, so daß die Führungsstege 3 eine sich über die Länge der Grundplatte 2 stetig ändernde Höhe aufweisen. In der normalen Gebrauchslage wird das Harscheisen 1 so auf dem Ski befestigt, daß die kürzeren Zähne näher an der Stiefel spitze liegen.As the drawing shows, a crampon, as it is generally designated by the reference number 1, consists of a base plate 2 and two lateral, downwardly projecting guide webs 3, which are brought into the form of a continuous row of teeth 5 by recesses 4 . The individual teeth 5 of the guide webs 3 are different long, so that the guide webs 3 have a continuously changing over the length of the base plate 2 height. In the normal position of use, the crampon 1 is attached to the ski so that the shorter teeth are closer to the boot tip.

Am vorderen Ende weist das Harscheisen 1 einen Ausleger 6 auf, der bei dem Ausführungsbeispiel nach Fig. 1 einstückig mit der Grundplatte 2 ausgebildet ist. An der Unterseite des Auslegers 6 ist eine Klemmfeder 7 angeordnet, die ein Festhaken des Harscheisens 1 an einer Stütze 8 ermöglicht, die Teil einer Tourenskibindung ist. Diese Bindung weist außerdem einen Lagerbock 9 und einen U-förmigen Bügel 11 auf, der an einer Lagerstelle 10 des Lagerbocks 9 schwenkbar gehalten ist und dessen Basisteil die zum Abstützen einer Stiefelsohle 12 dienende Stütze 8 trägt oder selbst bildet. Eine schwenkbare Spannvorrichtung 13 hält die Stiefelsohle auf der Stütze 8 fest, wobei ein Verschwenken des Skistiefels gegenüber dem Ski möglich ist, wie dies zum Tourengehen erforderlich ist.At the front end, the crampon 1 has a boom 6 which, in the exemplary embodiment according to FIG. 1, is formed in one piece with the base plate 2. On the underside of the boom 6, a clamping spring 7 is arranged, which enables the crampon 1 to be hooked onto a support 8 which is part of a touring ski binding. This binding also has a bearing block 9 and a U-shaped bracket 11 which is pivotally held at a bearing 10 of the bearing block 9 and whose base part carries or forms the support 8 which is used to support a sole 12 of the boot. A pivotable tensioning device 13 holds the boot sole firmly on the support 8, it being possible for the ski boot to pivot relative to the ski, as is necessary for touring.

In Fig. 2 ist eine abgeänderte Ausführungsform dargestellt. Der wesentliche Unterschied gegenüber dem Ausführungsbeispiel nach Fig. 1 besteht darin, daß der Ausleger 6.1 in Fig. 2 lösbar am Harscheisen 1 befestigt ist. Dazu weist der Ausleger 6.1 einen Längsschlitz 14 auf, mit dem er sich auf einen Niet 15 aufstecken und mit dessen Hilfe auf der Unterseite der Grundplatte 2 festklemmen läßt. Die Möglichkeit zu einer solchen lösbaren Auslegerbefestigung ist an beiden Enden der Grundplatte 2 vorgesehen, so daß der Ausleger 6.1 sowohl an dem Ende angebracht werden kann, wo die Zähne 5 der Führungsstege 3 länger sind, als auch an dem Ende, wo diese Zähne 5 kürzer sind.2 shows a modified embodiment. The main difference compared to the embodiment of FIG. 1 is that the boom 6.1 in Fig. 2 is releasably attached to the crampon 1. For this purpose, the boom 6.1 has a longitudinal slot 14, with which it can be plugged onto a rivet 15 and with the aid of which it can be clamped on the underside of the base plate 2. The possibility of such a releasable boom attachment is provided at both ends of the base plate 2, so that the boom 6.1 can be attached both at the end where the teeth 5 of the guide webs 3 are longer and at the end where these teeth 5 are shorter are.

In weiterer Abänderung gegenüber dem Ausführungsbeispiel nach Fig. 1 ist in Fig. 2 die Klemmfeder 7.1 im Querschnitt nicht kreisrund, sondern oval ausgebildet, und sie wirkt mit einer Stütze 8.1 von angepaßt ovalem Querschnitt zusammen. Damit ergibt sich eine Halterung, die dank der formschlüssigen Umfassung der Klemmfeder 7.1 mit von der Kreisform abweichendem Querschnitt ein ungewolltes Verdrehen des Harscheisens 1 verhindert. Daher kann der Ausleger 6.1 als nach oben durchgebogene Blattfeder ausgeführt werden, wodurch das Harscheisen 1 in der Gebrauchslage mit Vorspannung gegen die Unterseite der Stiefelsohle gehalten wird.In a further modification compared to the exemplary embodiment according to FIG. 1, the clamping spring 7.1 is not circular in cross-section but oval in FIG. 2, and it cooperates with a support 8.1 of an adapted oval cross-section. This results in a holder which, thanks to the form-fitting encirclement of the clamping spring 7.1 with a cross-section deviating from the circular shape, prevents unwanted twisting of the crampon 1. Therefore, the boom 6.1 as an upwardly bent leaf spring are carried out, whereby the crampon 1 is held in the use position with pretension against the underside of the sole of the boot.

Fig. 3 zeigt eine weitere Abwandlung des Harscheisens 1, wobei am Ausleger 6 ein Anschlag 16 für die Stiefelsohle 12 vorgesehen ist, wodurch eine bessere Anlage des Harscheisens 1 an der Stiefelsohle 12 und ein verbessertes Mitschwenken erreicht wird.Fig. 3 shows a further modification of the crampon 1, wherein a stop 16 is provided for the boot sole 12 on the boom 6, whereby a better contact of the crampon 1 on the boot sole 12 and an improved pivoting is achieved.

Die Darstellungen in Fig. 4 und 5 zeigen eine Ausführungsform mit einem an der Grundplatte 2 des Harscheisens 1 lösbar befestigbaren Ausleger 6.2, der mittels vier an der Grundplatte 2 angeordneter Mieten 18 gehalten ist, die jede in eine von vier schlüssellochförmigen Ausnehmungen 19 im Ausleger 6.2 eingreifen. Wie sich insbesondere aus Fig. 4 ersehen läßt, ist der Ausleger 6.2 unmittelbar vor seiner Auflage auf der Grundplatte 2 abgeknickt, so daß das Harscheisen 1 mit Vorspannung gegen die Stiefelsohle gedrückt wird. Auch hier ist ein Anschlag 16 vorhanden, der für eine gute Anlage des Harscheisens 1 an der Stiefelsohle sorgt, wobei die abgeknickte und federnde Ausführung des Auslegers 6.2 unterstützend mitwirkt.The illustrations in FIGS. 4 and 5 show an embodiment with a cantilever 6.2 which can be detachably attached to the base plate 2 of the crampon 1 and which is held by means of four rents 18 arranged on the base plate 2, each in one of four keyhole-shaped recesses 19 in the cantilever 6.2 intervention. As can be seen in particular from Fig. 4, the boom 6.2 is kinked immediately before it rests on the base plate 2, so that the crampon 1 is pressed against the boot sole with pretension. Here, too, there is a stop 16, which ensures that the crampon 1 is in good contact with the sole of the boot, the bent and resilient design of the jib 6.2 having a supporting effect.

Eine solche gute Anlage des Harscheisens 1 am Stiefel ist dann besonders wichtig, wenn entsprechend der Darstellung in Fig. 4 und 5 die Befestigung des Harscheisens 1 auf der Stütze 8 nur auf die Aufnahme von in Längsrichtung wirkenden Kräften eingerichtet ist. Bei dieser Ausführungsform sind an der Unterseite des Auslegers 6.2 zwei Stege 17 angeordnet, die einen dem Durchmesser der Stütze 8 entsprechenden Abstand voneinander aufweisen, so daß das Harscheisen 1 auf die Stütze 8 nur aufgesteckt wird und Halt nur in der Längsrichtung des Skis erfährt. Eine formschlüssige Halterung nach Art der Ausführungsform von Fig. 2 gibt es dagegen nicht, so daß ein Mitschwenken des Harscheisens 1 mit dem Stiefel auf andere Weise, nämlich durch den Anschlag 16 und die abgeknickte Ausführung des Auslegers 6.2 sichergestellt werden muß.Such a good contact of the crampon 1 on the boot is particularly important if, as shown in FIGS. 4 and 5, the fastening of the crampon 1 on the support 8 is set up only to absorb forces acting in the longitudinal direction. In this embodiment, two webs 17 are arranged on the underside of the boom 6.2, which have a distance from one another corresponding to the diameter of the support 8, so that the crampon 1 is only plugged onto the support 8 and is held only in the longitudinal direction of the ski. In contrast, there is no form-fitting mounting in the manner of the embodiment of FIG. 2, so that pivoting of the crampon 1 with the boot must be ensured in a different way, namely by means of the stop 16 and the bent version of the arm 6.2.
