Abstract

Steigeisen (2), das mindestens ein Scharnier (27) mit horizontaler Drehachse quer zur Laufrichtung oder mindestens ein Verbindungsstück aus einem elastisch biegsamen Material (45) aufweist, um das sich vorderer und hinterer Teil des Steigeisens gegeneinander drehen können, wobei dieses Scharniergelenk oder Materialstück durch mindestens einen quer zur Laufrichtung einsteckbaren oder verschiebbaren Arretierstift (35), durch einen längs zur Laufrichtung verschiebbaren Riegel (33) oder in sich starre Manschette (46) oder durch mindestens einen Riegel (33) arretiert werden kann, der dazu um jeweils eine Achse, die jeweils an einem der beiden Teile des Steigeisens befestigt ist, schwenkbar ist.Die Befestigungsvorrichtung (20) verbindet dabei das Steigeisen (2) durch eine Klemmkraft mit dem Schuh (1) lösbar, wobei das Steigeisen (2) einen äußeren Bügel (5) mit einem Verrbindungsgelenk (6) aufweist und der äußere Bügel (5) mit seinen Bügelenden (15) in einer Aufnahme (13) im Steigeisen (2) drehbar gelagert ist, wobei dem äußeren Bügel (5) ein innerer Bügel (4) zugeordnet ist, welcher in einer beidseitigen Aufnahme (3) in oder am Schuhabsatz (21) des Schuhs (1) drehbar angeordnet ist und über das Gelenk (6) mit dem ersten Bügel (5) verbunden ist, wobei die beiden Bügel (4, 5) eine Übertotpunkt-Befestigungsvorrichtung ausbilden.Bei den Zacken des Steigeisens besteht ihr unterer Teil, die Spitze (65), aus einem härteren Material als ihr oberer Teil, der Stummel (64), wobei beide Teile der Zacke zumindest in einem Teilbereich flächig aufeinanderliegen und mindestens ein zu dieser Kontaktfläche senkrecht stehender, massiver oder innen hohler Stift (67) in diesem Teilbereich beide Teile der Zacke mittels jeweils zweier deckungsgleicher, in beiden Teilen der Zacke vorhandener Löcher durchdringt, der an seinen beiden Enden jeweils verdickt oder / und gekrümmt oder / und mit mindestens einem Teil der Zacke verschweißt, verschraubt oder verklebt ist oder der als Schraube mit einer Schraubmutter ausgeführt ist. Mindestens einer der beiden Teile der Zacke ist in mindestens einem seiner beiden Seitenbereiche abgeknickt, sodass der obere Teil der Zacke im Bereich eines oder beider Seitenränder jeweils auf dem unteren Teil der Zacke aufliegt und so einen Anteil der auf den unteren Teil der Zacke von unten nach oben wirkenden Kraft aufnehmen kann, und / oder der eine Teil der Zacke fasst den jeweils anderen Teil ein, und zwar indem ein Zwischenraum gegeben ist, der der Materialdicke des jeweils eingefassten Teils der Zacke entspricht. Dieser Zwischenraum entsteht zwischen einerseits mindestens einem Finger, der dem einen Teil der Zacke entspringt, und andererseits der Kontaktfläche.Crampon (2) which has at least one hinge (27) with a horizontal axis of rotation transverse to the direction of travel or at least one connecting piece made of an elastically flexible material (45) around which the front and rear parts of the crampons can rotate against each other, this hinge joint or piece of material can be locked by at least one locking pin (35) that can be inserted or displaced transversely to the running direction, by a bolt (33) that can be displaced longitudinally to the running direction, or by a rigid sleeve (46) or by at least one bolt (33), which for this purpose can be locked around an axis , which is fastened to one of the two parts of the crampon, is pivotable. The fastening device (20) connects the crampon (2) releasably to the shoe (1) by a clamping force, the crampon (2) having an outer bracket (5 ) with a connecting joint (6) and the outer bracket (5) with its bracket ends (15) in a receptacle (13) in the crampon (2) dr is mounted in a removable manner, the outer bracket (5) being assigned an inner bracket (4) which is rotatably arranged in a receptacle (3) on both sides in or on the heel (21) of the shoe (1) and via the joint (6) is connected to the first bracket (5), the two brackets (4, 5) forming an over-center fastening device. With the prongs of the crampon, their lower part, the tip (65), consists of a harder material than their upper part, the stub (64), with both parts of the prong lying flat on top of each other at least in a partial area and at least one solid or internally hollow pin (67) perpendicular to this contact surface in this partial area, both parts of the prong by means of two congruent, in both parts of the Prong penetrates existing holes, which is thickened and / or curved and / or welded, screwed or glued to at least one part of the prong or as a screw with an S screw nut is executed. At least one of the two parts of the prong is kinked in at least one of its two side areas, so that the upper part of the prong in the area of one or both side edges rests on the lower part of the prong and thus a portion of the lower part of the prong from below Above acting force can absorb, and / or the one part of the prong surrounds the other part, namely in that there is a gap which corresponds to the material thickness of the respectively enclosed part of the prong. This gap is created between on the one hand at least one finger, which arises from one part of the prong, and on the other hand the contact surface.
