Description

Die Erfindung betrifft ein Kufensportgerät in Form eines Schlittschuhs, dessen Schuh mit einem als Wechselmesserhalter ausgebildeten Grundkörper verbunden ist, an welchem ein Wechselmesser lös- und verriegelbar befestigt ist.The invention relates to a Kufensportgerät in the form of a skate, the shoe is connected to a designed as an exchange knife holder body, to which a change-knife is releasably and lockably attached.

Kufensportgeräte, nämlich Schlittschuhe, mit auswechselbaren Stahlkufen sind aus verschiedenen Druckschriften, z. B. EP-A-0 427 920 , US 5 641 169 und AT 153 261 B bekannt.Skating sports equipment, namely skates, with interchangeable steel skids are from various documents, eg. B. EP-A-0 427 920 . US 5 641 169 and AT 153 261 B known.

Aus Stabilitätsgründen setzen diese Konstruktionen ein relativ stabiles, nämlich ausschließlich aus Stahl bestehendes, Laufmesser voraus.For stability reasons, these constructions require a relatively stable, namely made entirely of steel, running knife ahead.

Sie sind weniger geeignet für ein Kufensportgerät, dessen Kufe aus einem z. B. aus Kunststoff bestehenden Grundkörper mit einem an diesem auswechselbar befestigten Komposit-Laufmesser besteht, wie es aus DE 42 33 880 C1 bekannt ist.They are less suitable for a Kufensportgerät whose skid from a z. B. consisting of plastic body with a replaceable attached to this composite Laufmesser, as it is made DE 42 33 880 C1 is known.

Nach diesem Konzept gestaltete Schlittschuhe haben sich grundsätzlich in der Praxis bewährt.Skates designed according to this concept have basically proven themselves in practice.

Das als Wechselmesser dienende Komposit-Laufmesser ist bei diesen Schlittschuhen mit über seine Länge verteilten Schrauben mit dem Grundkörper verbunden.Serving as an exchange knife composite blade is connected in these skates with distributed over its length screws with the body.

Allerdings ist der Austausch dieses Wechselmessers wegen der Vielzahl von Schrauben noch relativ kompliziert und zeitaufwendig.However, the replacement of this change blade is still relatively complicated and time-consuming because of the large number of screws.

Zweckmäßiger ist die aus US 2 108 128 bekannte Lösung, bei welcher das Wechselmesser nach Art einer Kappe über den Wechselmesserhalter gestülpt ist und diesen teilweise umgreift.This is more useful US 2,108,128 Known solution in which the change-over knife is slipped over the change blade holder in the manner of a cap and this partially engages.

Die Stabilität und damit Belastbarkeit eines derart ausgebildeten und gehalterten Wechselmessers ist allerdings gering und für eine Fertigung aus Kunststoff völlig ungeeignet.However, the stability and thus load capacity of such a trained and salary Erten knife is low and completely unsuitable for a production of plastic.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Wechselmesser und den Wechselmesserhalter des im Oberbegriff des Anspruchs 1 definierten Kufensportgerätes so zu gestalten, dass die Verwendung eines teilweise aus einem spritzfähigen Material, insbesondere Kunststoff, bestehenden Komposit-Laufmessers möglich ist, das unter Verzicht auf Schraubverbindungen wie eine Kappe über den Wechselmesserhalter gestülpt werden kann und trotz dieser einfachen Verbindungsart eine hohe Belastbarkeit des Kufensystems gewährleistet ist.The present invention has for its object to make the change blade and the change blade holder defined in the preamble of claim 1 Kufensportgerätes so that the use of a partially made of a sprayable material, in particular plastic, existing composite Laufmessers is possible, dispensing with screw how a cap can be slipped over the change blade holder and despite this simple connection, a high load capacity of the skid system is guaranteed.

Gelöst wird diese Aufgabe bei einem Kufensportgerät der im Oberbegriff genannten Art mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen.This object is achieved with a skating sports equipment of the type mentioned in the preamble with the features stated in the characterizing part of claim 1.

Nach diesem Vorschlag weist das Wechselmesser einen Träger auf, in dessen Unterseite eine Laufschiene eingebettet ist.According to this proposal, the exchange knife on a support, in the bottom of a running rail is embedded.

Nach einem weiteren Merkmal besitzen der Wechselmesserhalter einen V-förmigen Querschnitt und der Wechselmesserträger eine dem Wechselmesserquerschnitt entsprechende V-förmige Aufnahme.According to a further feature of the exchange knife holder have a V-shaped cross-section and the diameter of the knife carrier a V-shaped cross-section corresponding V-shaped receptacle.

Durch die V-förmige Spreizung des Wechselmesserträgers und der V-förmigen Aufnahme des Wechselmesserhalters entsteht eine extrem stabile und spielfreie Verbindung dieser beiden Systemteile.The V-shaped spread of the knife carrier and the V-shaped receptacle of the exchangeable knife holder creates an extremely stable and backlash-free connection of these two system parts.

Außerdem kann, wie ferner mit der Erfindung vorgeschlagen ist der Wechselmesserhalter und der Wechselmesserträger aus Kunststoff oder einem anderen spritzfähigem Material bestehen, während die in den Wechselmesserträger eingebettete Laufschiene aus einem anderen Material, z.B. aus Stahl, besteht.In addition, as further proposed by the invention, the exchangeable blade holder and the blade carrier may be made of plastic or other sprayable material, while the track rail embedded in the blade carrier may be made of a different material, e.g. made of steel.

Die mit der Erfindung vorgeschlagene Verbindungstechnik, nach welcher der Wechselmesserträger den Wechselmesserhalter von außen V-förmig umgreift, ermöglicht die Aufnahme der bei hohen Beschleunigungs- und Kurvenfahrten auftretenden Querkräfte, die mit einer aus US 2 108 128 bekannten Konstruktion nicht aufgenommen werden könnten. Außerdem werden bei dieser Konstruktion fertigungsbedingte Toleranzen zwischen Wechselmesserhalter und Wechselmesserträger ausgeglichen.The proposed with the invention connection technology, according to which the change blade carrier the change blade holder from the outside engages V-shaped, allows the recording of the occurring during high acceleration and cornering lateral forces, with an off US 2,108,128 known construction could not be included. In addition, production-related tolerances between the knife holder and knife carrier are compensated in this design.

Die V-förmige Querschnittsform, bei welcher gemäß Anspruch 2 das V-förmige Wechselmesser den V-förmigen Wechselmesserhalter an seinen Außenkonturen spitzwinklig umschließt, führt dazu, dass das Kufensystem mit zunehmendem vertikalen Druck versteift wird.The V-shaped cross-sectional shape in which, according to claim 2, the V-shaped change blade at an acute angle encloses the V-shaped change blade holder at its outer contours, causes the Kufensystem is stiffened with increasing vertical pressure.

Aufgrund der hohen Formfestigkeit des Wechselmesserhalters kann das Wechselmesser mit in Front- und Heckbereich vorgesehenen Rastclipdrückern befestigt werden, wie diese mit Anspruch 3 vorgeschlagen sind.Due to the high dimensional stability of the exchange knife holder, the change-over knife can be fixed with provided in the front and rear area locking clips, as proposed in claim 3.

Die weiteren Vorschläge nach den Ansprüchen 4 bis 6 führen ohne Beeinträchtigung der werkzeuglosen Austauschbarkeit des Wechselmessers und ohne Gewichtserhöhung zu einer weiteren Verbesserung der Stabilität.The other proposals according to claims 4 to 6 lead without affecting the tool-free interchangeability of the change blade and without increasing the weight to further improve the stability.

Zur Schonung der Laufflächen und insbesondere der scharfen Messerkanten ist mit den Ansprüchen 7 und 9 eine an sich aus DE 31 04 483 C2 bekannter Kufenschoner vorgeschlagen, der jedoch an die besondere Konstruktion des erfindungsgemäßen Kufensportgerätes angepasst ist.To protect the running surfaces and in particular the sharp knife edges is with the claims 7 and 9 one in itself DE 31 04 483 C2 Known skid protectors proposed, however, which is adapted to the particular construction of Kufensportgerätes invention.

In den Zeichnungen ist eine erfindungsgemäß gestaltete Kufe dargestellt, welche mit der Kufenhalter-Sohlenplatte 4 und der Kufenhalter-Fersenplatte 5 an einem nicht dargestellten Schuh befestigbar ist.In the drawings, an inventively designed skid is shown, which is fastened to the skid holder sole plate 4 and the blade holder heel plate 5 on a shoe, not shown.

Die Kufe weist symmetrisch zur Mittellinie einen V-förmig ausgebildeten Wechselmesser-Halter 14 auf, der aus Kunststoff oder einem anderen spritzfähigen Material besteht. Am Wechselmesserhalter 14 ist das als Kompositbauteil ausgebildete Wechselmesser 1 befestigt. Es weist, wie in DE 42 33 880 Cl im Einzelnen erläutert, einen aus Kunststoff oder dergleichen Material bestehenden Träger 1a auf, in dessen Unterseite eine vorzugsweise aus Stahl bestehende Laufschiene 1b eingebettet ist, wie im einzelnen aus Figur 3 und 4 ersichtlich ist.The skid has symmetrical to the center line on a V-shaped change blade holder 14, made of plastic or another sprayable material. At the changer blade holder 14 designed as a composite component exchange knife 1 is attached. It points, as in DE 42 33 880 Explains in detail, a made of plastic or the like material carrier 1a, in the underside of a preferably existing steel rail 1b is embedded, as in detail FIG. 3 and 4 is apparent.

Das Wechselmesser 1 weist im vorderen und hinteren Bereich beidseitig Rastlöcher 17 auf, in welche in den Wechselmesserhalter integrierte, beidseitig angeordnete Rast-Clip-Drücker 2 einrasten.The change-over blade 1 has in the front and rear areas on both sides detent holes 17, in which engage in the change blade holder, arranged on both sides detent clip pushers 2 engage.

Um eine spielfreie Verrastung des Wechselmessers 1 am Wechselmesserhalter 14 mit den jeweiligen Rast-Clip-Drückern 2 zu gewährleisten, ist das Wechselmesser 1 im Bereich seiner Rastlöcher 17 gegen die Halterinnenseite vorgespannt, wie mit der gestrichelten Linie 13 in Figur 3 angedeutet ist.In order to ensure a backlash-free locking of the change blade 1 on the changer blade holder 14 with the respective locking clip pushers 2, the change blade 1 is biased in the region of its locking holes 17 against the holder inside, as with the dashed line 13 in FIG. 3 is indicated.

Zur Befestigung des Wechselmessers 1 am Wechselmesser-Halter 14 werden zunächst die im hinteren Bereich befindlichen Rast-Clip-Drücker 2 in die entsprechenden Rastlöcher 17 eingerastet, worauf das Wechselmesser in Figur 1 im Uhrzeigersinn gegen den vorderen Bereich des Wechselmesser-Halters 14 verschwenkt wird und das Wechselmesser 1 über die hintere Vorspannungslinie 10 sowie die vordere Vorspannungslinie 9 soweit nach oben gedrückt wird, bis die im vorderen Bereich befindliche und beidseitig am Wechselmesser-Halter 14 vorgesehenen Rast-Clip-Drücker 2 in die entsprechenden Rastlöcher 17 einrasten.To attach the change blade 1 on the change blade holder 14, the locking clip pushers 2 located in the rear area are first engaged in the corresponding locking holes 17, after which the change diameter in FIG. 1 is pivoted clockwise against the front portion of the exchangeable blade holder 14 and the change blade 1 on the rear bias line 10 and the front bias line 9 is pushed up until the located in the front region and provided on both sides of the change blade holder 14 locking clip Snap latch 2 into the corresponding detent holes 17.

Im ausgerasteten Zustand ist das Wechselmesser 1 vorgespannt, so dass es im vorderen und hinteren Bereich entsprechend den beiden Vorspannungslinien 9 und 10 eine Gegenkrümmung aufweist. Nach dem Einrasten der Rast-Clip-Drücker 2 in die vorderen und hinteren Rastlöcher 17 wird das Wechselmesser 1 mit der in den Wechselmesserhalter 14 integrierten Form- und Stabilisierungsleiste 16, welche Querkräfte am Wechselmesserträger 1a aufnimmt und der Längsachsenzentrierung dient, in seiner endgültigen Position am Wechselmesser-Halter 14 kraftschlüssig fixiert.In the disengaged state, the change blade 1 is biased so that it in the front and rear area corresponding to two bias lines 9 and 10 has a counter-curvature. After the latching clip-pushers 2 in the front and rear locking holes 17, the change blade 1 is integrated with the form and stabilizing bar 16 integrated in the changer holder 14, which receives transverse forces on the Wechselmesserträger 1a and the Längsachsenzentrierung, in its final position on Removable blade holder 14 fixed in a force-locking manner.

Die die Vorspannung bewirkende Gegenkrümmung des Wechselmessers 1 hat zur Folge, dass über die gesamte Länge des Wechselmessers 1, insbesondere im Bereich der vorderen und hinteren Rast-Clip-Drücker 2, eine konstante, vertikal gerichtete Spannung aufrechterhalten wird, durch welche ein spielfreier und kraftschlüssiger Sitz des Wechselmessers 1 am Wechselmesser-Halter 14 gewährleistet ist.The bias causing the counter-curvature of the change-over knife 1 has the consequence that over the entire length of the change blade 1, in particular in the region of the front and rear locking clip pushers 2, a constant, vertically directed voltage is maintained, through which a backlash-free and non-positive Seat of the changing blade 1 is guaranteed at the change blade holder 14.

Der Wechselmesserhalter 14 weist an seinem unteren Ende eine der Wandstärke der oben gelegenen Zungen des Wechselmessers 1 entsprechende Ausnehmung 8 auf, so dass das Wechselmesser 1 sich bündig an den Wechselmesserhalter 14 anschließt.The change blade holder 14 has at its lower end a the wall thickness of the tongues of the rotary blade 1 located above corresponding recess 8, so that the change blade 1 is flush with the change blade holder 14.

Wie die Zeichnungen erkennen lassen, weist das Wechselmesser 1 im vorderen und hinteren Bereich Schlitze 18 und 19 auf, mit welchen verhindert wird, dass die Außenwandungen des Wechselmessers 1 beim Aufsetzen auf den Wechselmesser-Halter 14, also bei Veränderung der Vorspannungslinien 9 und 10, deformiert werden.As can be seen from the drawings, the change-over knife 1 has slots 18 and 19 in the front and rear regions, which prevent the outer walls of the change-over blade 1 from being placed on the change blade holder 14, ie when the bias lines 9 and 10 are changed. be deformed.

Zur Abnahme des Wechselmessers 1 sind die vorderen und hinteren Rast-Clip-Drücker 2 gegeneinander und einwärts bis in die mit 15 in Figur 3 mit gestrichelten Linien angedeuteten Positionen aus den Rastlöchern 17 zu drücken, worauf das Wechselmesser 1 aufgrund seiner Vorspannungslinien 9 und 10 in Figur 1 angedeutete Position zurückfedert. Das Wechselmesser 1 kann nun ohne Kraftaufwand vom Wechselmesser-Halter 14 abgenommen werden. Das Einsetzen eines neuen Wechselmessers 1 erfolgt in umgekehrter Reihenfolge.To remove the change blade 1, the front and rear locking clip pushers 2 against each other and inwards to the 15 in FIG. 3 To push indicated by dashed lines positions from the locking holes 17, whereupon the change diameter 1 due to its bias lines 9 and 10 in FIG. 1 indicated position springs back. The change blade 1 can now be removed without effort by the change blade holder 14. The insertion of a new change diameter 1 is done in reverse order.

Die beschriebene Rast-Clip-Technik ist auch bei Verwendung von herkömmlichen Vollstahlmessern geeignet.The locking clip technique described is also suitable when using conventional solid steel knives.

In diesem Fall ist das Stahlmesser mit Rastlöcher aufweisenden Zungen auszustatten, welche angespritzt, angeklebt oder angeschweißt sind, wobei das Vollstahlmesser anstelle der Formleiste 16 in einen im Wechselmesser-Halter 14 befindlichen Schlitz eingesteckt wird, der entlang der Längsachse des Wechselmessers 14 verläuft.In this case, the steel knife is to be equipped with locking holes having tongues which are molded, glued or welded, the solid steel knife is inserted instead of the mold bar 16 in a slot located in the changer holder 14 slot extending along the longitudinal axis of the change blade 14.

Die spezielle Bauweise des erfindungsgemäßen Wechselmessers 1 gestattet minimale Wandstärken, da die vorn und hinten beidseitig vorgesehenen, dünnwandigen, flexiblen Zungen, in welchen sich die Rastlöcher 17 befinden, für ausreichende Steifigkeit der Wand sorgen. Diese Zungen sind derart vorgespannt, dass sie vor Aufschieben des Wechselmessers auf den Wechselmesserhalter 14, also im nicht aufgespreizten Zustand, die in Figur 3 mit gestrichelten Linien 13 angedeutete Position einnehmen. Diese Vorspannung gewährleistet durch die optimale Konturanpassung zwischen dem Wechselmesserhalter 14 und dem Wechselmesserträger 1 sowie den Rast-Clip-Drückern 2 und den Rastlöchern 17 einen spielfreien Sitz.The special construction of the rotary knife 1 according to the invention allows minimum wall thicknesses, since the front and rear provided on both sides, thin-walled, flexible tongues, in which the detent holes 17 are provided for sufficient rigidity of the wall. These tongues are pretensioned in such a way that, before the change-over knife is pushed onto the change-over knife holder 14, that is to say in the non-spread state, they are in FIG. 3 assume with dashed lines 13 indicated position. This bias ensured by the optimal contour fit between the change blade holder 14 and the knife carrier 1 and the locking clip pushers 2 and the locking holes 17 a backlash-free seat.

Für die erforderliche Stabilität des extrem dünnwandigen und damit leichten Wechselmessers 1 sorgt die in den Wechselmesser-Halter 14 integrierte Form- und Stabilisierungsleiste 16, welche tief in den im Wechselmesser 1 vorgesehenen Schlitz eintaucht.For the required stability of the extremely thin-walled and thus easy change blade 1, the integrated into the change blade holder 14 form and stabilizing bar 16, which dives deep into the slot provided in the change blade 1 slot.

Diese Wechselmessergestaltung ermöglicht einen problemlosen, einfachen und extrem schnellen Austausch des Wechselmessers 1 ohne mechanische Hilfsmittel.This change blade design allows a trouble-free, easy and extremely fast replacement of the change-over blade 1 without mechanical aids.

Die spezielle V-förmige Kontur in Verbindung mit der in dem Wechselmesser-Halter 14 integrierten Form- und Stabilisierungsleiste 16 gewährleistet bei vergleichsweise geringem Gewicht eine äußerst wirksame und belastbare Verbindung zwischen Wechselmesser 1 und Wechselmesser-Halter 14. Die mit den Rastlöchern 17 zusammenwirkenden Rast-Clip-Drücker 2, die im vorderen und hinteren Bereich angeordnet sind, ermöglichen bei Anwendung geringer Kraft einen schnellen Austausch abgenutzter Messer gegen neue Messer in weniger als zehn Sekunden. Auch ist die Herstellung eines Kufensystems mit diesem Kompositmesser problemlos und kostengünstig.The special V-shaped contour in conjunction with the integrated molding and stabilizing bar 16 in the change blade holder 14 ensures at comparatively low weight an extremely effective and resilient connection between change diameter 1 and change blade holder 14. The cooperating with the detent holes 17 detent Clip pushers 2, located in the front and back areas, allow quick replacement of worn knives for new knives in less than ten seconds when using low force. Also, the production of a skid system with this Kompositmesser is easy and inexpensive.

Zeitaufwändiges Kufenschleifen und kostenintensive Wartungs-und Instandhaltungsarbeiten, die nur durch teure Fachkräfte bei Verwendung teurer Schleifmaschinen ausgeführt werden können, entfallen.Time-consuming skid-grinding and cost-intensive maintenance and repair work, which can only be performed by expensive specialists using expensive grinding machines, are eliminated.

Ein von einer Fachkraft in herkömmlicher Weise mit relativ teuren Schleifmaschinen durchgeführter Kufenschliff benötigt bei normaler Kantenabnutzung etwa die 15-fache Arbeitszeit bei schlechterer Qualität der Kufenkanten und der Gleitoberfläche.A blade grinding performed by a skilled person in a conventional manner with relatively expensive grinding machines requires about 15 times the working time with poor quality of the edge edges and the sliding surface with normal edge wear.

Wie die Figuren 1, 2 und 6 deutlich machen, sind die Kufenhalter-Sohlenplatte 4 und die Kufenhalter-Fersenplatte 5 über diagonal und schräg zueinander verlaufende, sich kreuzende Torsions- und Biegestäbe 3a und 3b mit dem Wechselmesser-Halter 14 im hinteren bzw. dessen vorderen Bereich verbunden. Wie ferner erkennbar ist, verbinden die Torsions- und Biegestäbe 3a, 3b unter Bildung eines Torsionsdoppelkreuzes 3 den Randbereich der Kufenhalter-Sohlenplatte 4 bzw. der Kufenhalter-Fersenplatte 5 mit dem jeweils gegenüberliegenden Randbereich des Wechselmesser-Halters 14. Dieses Torsionsdoppelkreuz 3 dient der Reduzierung der im Wechselmesser 1 und dem Wechselmesser-Halter 14 bei Gebrauch entstehenden Torsions- und Biegekräfte. Hierdurch werden die durch laufdynamische Einwirkung entstehenden Torsions- und Biegekräfte zwischen der Kufenhalter-Sohlenplatte 4 bzw. der Kufenhalter-Fersenplatte 5 und dem das Wechselmesser 1 tragenden Wechselmesser-Halter 14 aufgefangen und weitgehend neutralisiert.As the FIGS. 1 . 2 and 6 make clear that the blade holder sole plate 4 and the blade holder heel plate 5 are arranged on diagonally and obliquely extending, intersecting torsional and bending bars 3a and 3b are connected to the exchangeable blade holder 14 at the rear and the front thereof, respectively. As can also be seen, connect the torsion and bending rods 3a, 3b to form a Torsionsdoppelkreuzes 3, the edge region of the blade holder sole plate 4 and the blade holder heel plate 5 with the respective opposite edge region of the change blade holder 14. This Torsionsdoppelkreuz 3 serves to reduce the change in diameter 1 and the diameter changer holder 14 resulting in use torsional and bending forces. As a result, the resulting torsional and bending forces between the blade holder sole plate 4 and the blade holder-heel plate 5 and the change blade 1 bearing change blade holder 14 are collected and largely neutralized.

Zwischen Torsionsdoppelkreuz 3 und dem Wechselmesser-Halter 14 sind Durchbrüche 7 ausgebildet, welche ohne Verlust der Stabilität zu einer Gewichtsminderung führen.Between Torsionsdoppelkreuz 3 and the change blade holder 14 breakthroughs 7 are formed, which lead to a loss of weight without loss of stability.

Eine weitere Verbesserung der Stabilität und damit eine verbesserte Aufnahme von Torsions- und Biegekräften bewirkt die in Figur 2 erkennbare Gestaltung der Kufenhalter-Sohlenplatte bzw. Fersenplatte 4 und 5.A further improvement of the stability and thus an improved absorption of torsional and bending forces causes the in FIG. 2 recognizable design of the blade holder sole plate or heel plate 4 and 5

Diese Platten bestehen jeweils aus einem in sich geschlossenen Ring 4a und 5a, in welchem zur Bildung eines Torsionskreuzes 11 bzw. 12 diagonal verlaufende, sich im Mittelpunkt kreuzende Speichen 11a, 11b bzw. 12a, 12b vorgesehen sind.These plates each consist of a self-contained ring 4a and 5a, in which to form a torsion cross 11 and 12 diagonally extending, in the center crossing spokes 11a, 11b and 12a, 12b are provided.

Auch vertikal auf das Wechselmesser 1 wirkende Kräfte werden von den Torsions- und Biegestäben 3a, 3b des TorsionsDoppelkreuzes 3 aufgenommen und weitestgehend neutralisiert.Also acting vertically on the change blade 1 forces are absorbed by the torsion and bending rods 3a, 3b of the TorsionsDoppelkreuzes 3 and largely neutralized.

Wegen der durch das Torsions-Doppelkreuz erzielten Verwindungs- und Biegesteifigkeit können Wechselmesser-Halter 14 mit vergleichsweise geringen Wandstärken verwendet werden, was zum einen zur Gewichtsreduzierung und zum anderen zur Herabsetzung der Herstellkosten und damit der Verkaufspreise führt.Because of the torsional and bending stiffness achieved by the torsion doubler, change-blade holders 14 can be used with comparatively small wall thicknesses, resulting firstly in weight reduction and secondly in reducing the production costs and thus the selling prices.

Zur Schonung der Lauffläche und insbesondere der Kanten der Laufschiene 1b und um sicheres Gehen außerhalb von Eisflächen zu ermöglichen, kann, wie mit den Figuren 3 und 6 veranschaulicht, auf den Wechselmesser-Halter 14 ein das Wechselmesser 1 vollständig überdeckender Kufenschoner 20 aufgesetzt werden. Er weist an seinem vorderen und hinteren Ende gegeneinander gerichtete Zapfen 21 und 22 auf, welche in die Durchbrüche 2a der ringförmig gestalteten und in die Rastlöcher 17 eingreifenden Rast-Clip-Drücker 2 einrasten. Den Rastzapfen 21 und 22 sind am oberen Rand des Kufenschoners 20 vorgesehene Entriegelungszungen 23 zugeordnet, mit welchen die Zapfen 21 und 22 gegen die Federwirkung des aus elastischem Material bestehenden Kufenschoners 20 nach außen gedrückt werden können, bis die Zapfen 21 bzw. 22 aus den Ausnehmungen 2a ausrasten, worauf der Kufenschoner 20 abgenommen werden kann. Die Seitenwände des im Querschnitt U-förmig gestalteten Kufenschoners 20 sind mit über die Länge verteilten Schlitzen 24 ausgestattet, wodurch die Flexibilität des Kufenschoners 20 erhöht und dieser konturgenau an den Wechselmesser-Halter 14 mit dem Wechselmesser-1 angepasst und mit diesem verrastet werden kann.To protect the tread and in particular the edges of the rail 1b and to allow safe walking outside of ice, can, as with the Figures 3 and 6 illustrates, on the change blade holder 14, a change blade 1 completely overlapping Kufenschoner 20 are placed. He has at its front and rear end against each other directed pins 21 and 22, which engage in the openings 2a of the annular shaped and engaging in the locking holes 17 locking clip pushers 2. The locking pins 21 and 22 are provided at the upper edge of the skid shoe 20 unlocking tongues 23, with which the pins 21 and 22 can be pressed against the spring action of the existing elastic material skid shoe 20 to the outside until the pins 21 and 22 from the recesses 2a disengage, after which the skid protector 20 can be removed. The side walls of the cross-sectionally U-shaped runner protector 20 are provided with slots 24 distributed over the length, whereby the flexibility of the runner protector 20 increases and this contour can be adapted to the change blade holder 14 with the change blade-1 and locked with this.

Bei dieser exakten Passform kann der Kufenschoner 20 aus einem leichten, extrem flexiblen und trittsicheren Material, vorzugsweise Kunststoff, bestehen.In this exact fit, the skid shoe 20 may consist of a lightweight, extremely flexible and sure-footed material, preferably plastic.
