Description

Die Erfindung betrifft eine Langlauf-Skibindung mit den Merkmalen gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a cross-country ski binding with the features according to the preamble of claim 1.

Eine bekannte Langlauf-Skibindung der vorstehend geschilderten Art DE-A Nr. 2643223 weist eine Halterung auf, die im wesentlichen aus einem das vordere Ende einer Sohlenverlängerung des Langlauf-Skischuhes um- und übergreifenden Bügel sowie aus einem den Bügel übergreifenden Verriegelungselement besteht. Das Verriegelungselement ist eine Klammer oder Spange, die an ihrem hinteren Ende ein Hakenelement aufweist, mit dem sie in der Spannstellung sowohl die Hinterkante des Bügels als auch eine nach hinten weisende Schulter der Sohlenverlängerung hintergreift. Am vorderen Ende der Klammer ist an deren beiden Längsseiten je eine Führungsrolle gelagert, die auf einer jeweils zugeordneten Führungskurve so abrollen kann, dass die Klammer etwa um das Hakenelement als Schwenkpunkt auf- und abbewegbar ist. Die Führungskurve weist zwei Rastausnehmungen auf, in welche die Führungsrolle durch eine an der Klammer angreifende Zugfeder eingezogen wird und von denen die obere die Freigabestellung und die untere die Spannstellung der Klammer bestimmt. In der Spannstellung ist das Hakenelement der Klammer hinter und unter der nach oben schräg abgebogenen Hinterkante des Bügels gehalten.A known cross-country ski binding of the type DE-A No. 2643223 described above has a holder which essentially consists of a strap which encompasses and overlaps the front end of a sole extension of the cross-country ski boot and a locking element which overlaps the strap. The locking element is a clip or clasp, which has a hook element at its rear end, with which it engages behind both the rear edge of the bracket and a rear-facing shoulder of the sole extension in the tensioned position. At the front end of the clip, a guide roller is mounted on each of its two longitudinal sides, which can roll on an associated guide curve in such a way that the clip can be moved up and down about the hook element as a pivot point. The guide curve has two locking recesses into which the guide roller is drawn in by a tension spring acting on the clamp and of which the upper determines the release position and the lower the clamping position of the clamp. In the tensioned position, the hook element of the clip is held behind and under the rear edge of the bracket, which is bent upwards at an angle.

Die bekannte Langlauf-Skibindung besteht aus einer Mehrzahl von Einzelteilen und ist daher in Herstellung und Montage aufwendig, was sich im Preis auswirkt. Ausserdem besteht die Gefahr, dass das Zusammenwirken dieser Einzelteile (z. B. der Führungsrollen auf der Führungskurve oder die die Klammer beaufschlagende Zugfeder) durch bei der Benutzung eindringenden Schnee oder Schmutz beeinträchtigt wird, so dass die Funktion gestört wird.The well-known cross-country ski binding consists of a plurality of individual parts and is therefore complex to manufacture and assemble, which has an impact on the price. In addition, there is a risk that the interaction of these individual parts (e.g. the guide rollers on the guide curve or the tension spring acting on the clamp) will be impaired by snow or dirt entering during use, so that the function is disturbed.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Langlauf-Skibindung dieser Art zu schaffen, die einfacher aufgebaut und gegen Funktionsstörungen weniger anfällig ist.The invention is therefore based on the object of creating a cross-country ski binding of this type which is of simpler construction and is less susceptible to malfunctions.

Erfindungsgemäss wird diese Aufgabe gelöst durch die Merkmale gemäss dem Kennzeichen des Patentanspruches 1.According to the invention, this object is achieved by the features according to the characterizing part of patent claim 1.

Die erfindungsgemässe Langlauf-Skibindung besteht in der angegebenen Ausführungsform nur aus zwei Teilen, nämlich aus der den Bügel aufweisenden Halterung und der Klammer. Die Klammer besteht aus einem festen, jedoch biegeelastisch verformbaren Werkstoff, z. B. Polyamid oder Polyurethan, dessen elastische Biegeverformbarkeit ausreichend ist, um unter Ausnutzung der Führungswirkung der genannten Führungsfläche die Klammer auf die Halterung aufschnappen zu lassen, so dass das Hakenelement die Hinterkante des Bügels und die vordere Fläche der Ausnehmung, zu der hin die Führungsfläche führt, die erwähnte, zur Bügelhinterkante parallele Kante umgreifen. Der sich nach vorne erstreckende Klammerfortsatz stützt sich dabei auf der Skioberseite, z. B. über eine sich von der Halterung aus nach vorne erstreckende Grundplatte der Skibindung, ab und bestimmt dadurch die Anlageposition der Bügelhinterkante und der davor liegenden Kante an den jeweils zugeordneten Flächen in der Spannstellung. Durch Hochheben des Klammerfortsatzes kann die Klammer wieder in eine Freigabestellung verbracht werden, wobei die Klammer im wesentlichen um den Anlagepunkt der Bügelhinterkante an der Innenfläche des Hakenelements verschwenkt und die vordere Innenfläche der Ausnehmung an der erwähnten vorderen Kante bei gleichzeitiger elastischer Aufbiegung der Klammer entlang gleitet, bis sie die Kante freigibt. Die Klammer vereinigt somit aufgrund der geschilderten Ausgestaltung Halte-, Führungs- und Rastfunktion.The cross-country ski binding according to the invention consists in the specified embodiment only of two parts, namely the bracket having the bracket and the clip. The clip consists of a solid, but flexible, deformable material, e.g. As polyamide or polyurethane, the elastic bending deformability is sufficient to snap the clip onto the holder, taking advantage of the guiding action of the said guiding surface, so that the hook element traces the rear edge of the bracket and the front surface of the recess, to which the guiding surface leads , grasp the mentioned edge parallel to the rear edge of the frame. The forwardly extending bracket extension is supported on the top of the ski, for. B. from a bracket extending forward from the base of the ski binding, and thereby determines the contact position of the rear edge of the frame and the edge in front of it on the respectively assigned surfaces in the clamping position. By lifting the clip extension, the clip can be brought back into a release position, the clip pivoting essentially around the point of contact of the rear edge of the bracket on the inner surface of the hook element and the front inner surface of the recess sliding along the aforementioned front edge with simultaneous elastic bending of the clip, until she releases the edge. The bracket thus combines holding, guiding and locking function due to the described design.

Dadurch, dass für die geschilderte Betätigung der Skibindung nur eine Realtivbewegung zwischen der Klammer und den erwähnten Kanten erforderlich ist, weitere bewegliche Teile aber nicht vorhanden sind, und in der Spannstellung durch das Umgreifen der Bügelhinterkante und der davor liegenden Kante ein geschlossener, von aussen nicht zugänglicher Raum gebildet ist, kann eindringender Schnee und Schmutz die Funktionsfähigkeit der Bindung nicht beeinträchtigen.Due to the fact that only a real movement between the clamp and the mentioned edges is required for the described actuation of the ski binding, but there are no other moving parts, and in the tensioned position by reaching around the rear edge of the frame and the edge in front of it, a closed one, from the outside not accessible space is formed, penetrating snow and dirt cannot impair the functionality of the binding.

Zweckmässigerweise ist die vor der Bügelhinterkante liegende Kante, die in der Spannstellung mit der Ausnehmung in Kontakt kommt, die Bügelvorderkante, so dass die Breite des Bügels das für den Abstand zwischen Hakenelement und Führungsfläche bestimmende Mass ist.The edge in front of the rear edge of the frame, which comes into contact with the recess in the tensioned position, is expediently the front edge of the frame, so that the width of the frame is the measure determining the distance between the hook element and the guide surface.

Für die beschriebene Funktion ist ein fester Zusammenhalt zwischen Klammer und Halterung in der Freigabestellung im Prinzip nicht erforderlich. Um jedoch zu verhindern, dass die Klammer als loses Teil gehandhabt werden muss, ist nach einer weiteren Ausgestaltung vorgesehen, dass die Halterung zu beiden Seiten des Bügels sich nach vorne erstreckende Seitenwände aufweist, an denen die Klammer beweglich befestigt ist. Diese Befestigung braucht jedoch keinerlei ins Gewicht fallende Belastung zu übernehmen, sondern dient nur dazu, ein unerwünschtes Lösen der Klammer von der Halterung in der Freigabestellung zu verhindern. Es ist deshalb möglich, die Klammer und die Seitenwände so auszubilden, dass sie nach Art einer elastischen Schnappverbindung ineinandergefügt und leicht voneinander gelöst werden können. Das ermöglicht auch im Bedarfsfall den Austausch der Klammer.In principle, a firm cohesion between the bracket and the holder in the release position is not required for the function described. However, in order to prevent the clip from having to be handled as a loose part, it is provided according to a further embodiment that the holder has side walls which extend forward on both sides of the bracket and to which the clip is movably fastened. However, this attachment does not have to take on any significant weight, but only serves to prevent undesired loosening of the clip from the holder in the release position. It is therefore possible to design the clip and the side walls in such a way that they can be fitted into one another in the manner of an elastic snap connection and can be easily detached from one another. This also enables the clip to be replaced if necessary.

Die erfindungsgemässe Skibindung ergibt nach einer weiteren Ausgestaltung auch die Funktion einer Sicherheitsbindung, d. h. einer selbsttätigen Lösung der Klammer von der Halterung für den Fall eines übermässigen Anhebens und Abbiegens des Fusses nach vorne. Hierzu ist an dem Hakenelement eine nach hinten vorspringende Hebelfläche vorgesehen, die bei normaler Benutzung ausser Kontakt mit der Oberseite der Sohlenverlängerung des Langlauf-Skischuhes bleibt. Stürzt jedoch der Skiläufer nach vorne und biegt sich dabei sein Fuss übermässig nach oben und vorne, so kommt die Oberseite der Sohlenverlängerung an der Hebelfläche zur Anlage und erzeugt dadurch ein Drehmoment an der Klammer in Richtung auf eine Auslösung des Hakenelements aus dem Fin griff mit der Bügelhinterkante. Da sich die Klaromer mit der Stützfläche des Klammerforsetzes auf der Skioberseite abstützt, wirkt sich dieses Drehmoment in einer elastischen Verbiegung des den Bügel umgreifenden Klammerteins aus so dass in Abhängkeit von der Grösse des Drehmome ein Heraussechnapen der Klammer aus dem Ein griff bewirkt wird. Nach einer Weiterbildung de Erfindung, die darin besteht, dass die Stützfläche an dem Klammerfortsatz an einem höhenverstell baren Element ausgebildet ist, kann dieLöcokraft eingestellt werden. Denn hierdurch wird dieAnlageposition der Bügelkanten an derKlammer in de. Spannstellung verändert, sondert, dass bie Zur Freigebe ein kürzerer oder längerer Weg zurückgelegt wer den muss.According to a further embodiment, the ski binding according to the invention also provides the function of a safety binding, ie an automatic release of the clip from the holder in the event of excessive lifting and bending of the foot forward. For this purpose, a lever surface projecting backwards is provided on the hook element, which remains out of contact with the upper side of the sole extension of the cross-country ski boot during normal use. However, if the skier falls forward and his foot bends excessively upwards and forwards, the top of the sole extension comes into contact with the lever surface and thereby creates a torque on the bracket in the direction of triggering the hook element from the fin reached with the rear edge of the bracket. Since the Klaromer is supported with the support surface of the clamp extension on the top of the ski, this torque results in an elastic bending of the clamp stone encompassing the bracket, so that depending on the size of the torque, the clamp is snapped out of the grip. According to a further development of the invention, which consists in the support surface on the clip extension being formed on a height-adjustable element, the locomotive force can be adjusted. Because this makes the contact position of the temple edges on the bracket in the Tension position changes, except that a shorter or longer distance has to be covered to release.

Die in den Fig. 1 und 6, 7 dargestellte Skibin dung besteht aus nur zwei relativ zueinander beweglichen Teilen, nämlich aus einer auf der Oberseite 1 eines Skis befestigbaren Halterung 2 und einer an der Halterung 2 befestigten Klammer 3. Die aus Metall oder Kunststoff bestehende Halterung 2 weist eine im wesentlichen rechteckige Grundplatte 21 auf, von deren beiden Längsseiten senkrechte Seitenwände 22 nach oben vorspringen, die in ihrem hinteren Bereich zueinander divergierende Schenkel 23 bilden. Zwischen ihren vorderen und hinteren Enden sind die Seitenwände 22 durch einen Bügel 24 brückenartig miteinanderverbunden, dessen Hinterkante 25 und Vorderkante 26 gerundetsind (Fig. 2). Von dem Bügel 25 aus nach vorne nehmen Höhe und auch Dicke der Seitenwände 22 zu (Fig. 2, 3) und die zueinander gewandten Innenflächen der Seitenwände 22 weisen je eine flache Vertiefung 27 auf, die angenähertdie Form eines Rechtecks besitzt und allseitig umschlossen ist. Zur Befestigung der Halterung 2 auf der Skioberfläche dienen Schrauben 28, die entsprechende Löcher in der Grundplatte 21 durchsetzen.1 and 6, 7 Skibin extension consists of only two relatively movable parts, namely a mountable on the top 1 of a ski bracket 2 and a bracket 2 attached to the bracket 3. The existing metal or plastic Bracket 2 has an essentially rectangular base plate 21, from the two longitudinal sides of which vertical side walls 22 project upward, which form legs 23 which diverging from one another in their rear region. Between their front and rear ends, the side walls 22 are connected in a bridge-like manner by a bracket 24, the rear edge 25 and the front edge 26 of which are rounded (FIG. 2). The height and also the thickness of the side walls 22 increase from the bracket 25 to the front (FIGS. 2, 3) and the mutually facing inner surfaces of the side walls 22 each have a flat depression 27 which approximately has the shape of a rectangle and is enclosed on all sides. Screws 28, which pass through corresponding holes in the base plate 21, are used to fasten the holder 2 to the ski surface.

Die Klammer 3 besteht aus einem harten, jedoch elastisch biegeverformbaren Kunststoff, z. B. aus Polyamid oder Polyurethan, und ist an ihrem hin teren Ende zu einem Hakenelement 31 geformt dem in einem Abstand nach vorne, der geringen als die Breite des Bügels 24, eine Führungsfläche 32 gegenüberliegt. Die Führungsfiäche 32 bilder die vordere untere Begrenzungsfläche einer quer verlaufenden. im Querschnitt annähernd tailellip tischen Ausnehmung 33, die sich ausgehend von der Führungsfläche 32 und von der Spitze des Hokenelements 31 nach innen zu erweitert. Durch die beschriebene Querschnittsgestaltung der Ausnehmung 33 besitzt die Klammer 3 in dem Bereich 34 vor dem Hakene!ement 31 eine garingere Wandstärke, die eine elastische Verbiegbarkeit de Klammer in diesem Bereich ergibt.The bracket 3 consists of a hard, but elastically bend-deformable plastic, for. B. made of polyamide or polyurethane, and is formed at its rear end to a hook element 31 which is at a distance forward, which is less than the width of the bracket 24, a guide surface 32 opposite. The guide surface 32 forms the front lower boundary surface of a transverse one. in cross-section approximately tailellip table recess 33, which extends from the guide surface 32 and from the tip of the hook element 31 to the inside. Due to the described cross-sectional design of the recess 33, the clamp 3 in the area 34 in front of the hook element 31 has a thinner wall thickness, which results in an elastic bendability of the clip in this area.

Von einem vor der Führungsfläche 32 liegenden Mittelabschnitt 35 der Klammer, der im wessenti chen massiv ausgebildet ist, erstreckt sich ein Klammerfortsatz 36 bogenförmig nach vome und stützt sich in der in Fig. 1 gezeigten Spannsteliang über eine Stützfläche 37 auf der Skioberseize Die Stütztfläche 37 ist von dem Kopf eine Stell schraube 38 gebiidet, die mittels eines selbsthen menden Gewindes in den Klammerfortsatz 36 ein geschraubt ist und daher sich nicht selbsttätig ver drehen kann. Die Stellschraube 38 ragt mit ihred gerändelten Umfangsfläche geringfügig Über die nach vorne spitz zulaufende Oberfläche des Klam merfortsatzes 36 vor (vgl. Fig. 4, 5). Zwischen dem Mittelteil 35 und der Stellschraube 38 bildet der Klammerfortsatz eine von beiden Seiten hel zu gängliche Öffnung 39, in die der Skiläufer mit dem Stock oder dem Finger eingreifen kann, um zum Zweck der Lösung den Klammerfortsatz 36 nach oben zu ziehen.From a central portion 35 of the clip lying in front of the guide surface 32, which is solid in essence, a clip extension 36 extends in an arc towards the front and is supported in the tensioning triangle shown in FIG. 1 via a support surface 37 on the ski upper surface. The support surface 37 is from the head a set screw 38 is formed, which is screwed by means of a self-threading into the bracket extension 36 and therefore cannot rotate automatically. The set screw 38 protrudes slightly with its knurled circumferential surface over the tapered surface of the clamp extension 36 (see FIGS. 4, 5). Between the middle part 35 and the screw 38 of the bracket extension forms one of the two sides he l to gängliche opening 39 into which the skier can engage with the stick or the fingers, to pull the clip projection 36 upward for the purpose of the solution.

An den gegenüberliegenden Seitenflächen des Mittelabschnittes 35 ist je eine elastisch federnde Zunge 40 mit einem nach aussen vorsprmsenden zylindrischen Ansatz 41 angeformt, die in einen Hohlraum 42 hinein ausweichen kann. Wie sich aus Fig. 1 ergibt, ist die Klammer 3 durch form schlüssige Halterung der Ansätze 41 in der Vertiefung 27 gehalten, wobei durch einen Druck auf die Zungen 40 nach innen und die dadurch bedingte elastische Einbiegung die Klammer 3 von der Halterung 2 gelöst werden kann Zur Erleichterung des Einfügens und des Lösens können die Ansätze 41 oben und unten nicht gezeigte Schrägflächen aufweisen.An elastically resilient tongue 40 is formed on each of the opposite side surfaces of the central section 35 with a cylindrical extension 41 projecting outwards, which can escape into a cavity 42. As can be seen from FIG. 1, the clamp 3 is held in the recess 27 by form-fitting mounting of the lugs 41, the clamp 3 being detached from the mounting 2 by pressing the tongues 40 inwards and the resulting elastic deflection The lugs 41 can have inclined surfaces, not shown above and below, to facilitate insertion and detachment.

Die Fig. 6 zeigt die Stellung der Klammer 3 unmittelbar vor dem Aufdrücken auf den Bügel 24. Um eine nach hinten weisende Schulter 4 des verdickten Endbereiches einer vorderen Sohlenverlängerung 5 eines Langlauf-Skischuhes 6 in der Halterung 2 einzuspannen, wird nach dem Einfügen des Endbereiches unter den Bügel 24 die Klammer 3 in die aus Fig. 6 ersichtliche Stellung bewegt, bei der die Spitze des Hakenelementes 31 die Bügelhinterkante 25 knapp untergreift. In dieser Stellung befindet sich aufgrund der vorstehend geschilderten Bemessung der Ausnehmung 33 die Führungsfläche 32 in Kontakt mit der Oberseite des Bügels 24, d. h. ohne Kraftaufwendung in Richtung des Pfeiles 7 kann ein Eingriff der Ausnehmung 33 in den Bügel 24 nicht hergestellt werden. Da jedoch die gerundete Führungsfläche 32 in Verbindung mit der Anlage an der Bügelvorderkante 26 unter der in Richtung des Pfeiles 7 wirkenden Aufdrückkraft eine Keilwirkung entfaltet, wird dadurch die Ausnehmung 33 unter gleichzeitiger Biegeverformung der Klammer 3 aufgeweitet, so dass der Bügel 24 in die Ausnehmung 33 einschnappen kann. In der dadurch herbeigeführten Spannstellung, die aus Fig. 1 ersichtlich ist, liegt die Stützfläche 37 des Klammerfortsatzes 36 auf der Skioberseite 1 auf und verhindet dadurch ein weiteres Einfügen des Bügels 24 in die Ausnehmung 33. Aufgrund der Divergenz der Innenflächen der Ausnehmung 33 im Bereich des Hakenelement 31 und anschliessend an die Führungsfläche 32 und aufgrund der elastischen Vorspannung, die die genannten Flächen an die Bügelvorder- und Hinterkanten andrückt, sitzt die Klammer 3 fest in der Halterung 2 und untergreift mit dem Hakenelement 31 die Schulter 4. Dadurch wird ein Herausziehen der Sohlenverlängerung 5 unter dem Bügel 24 verhindert. Ein weiteres Einschieben nach vorne verhindern die divergierenden Schenkel 23 der Halterung 2, die an entsprechenden, nicht gezeigten Seitenflanken der Sohlenverlängerung 5 anliegen.Fig. 6 shows the position of the clamp 3 immediately before pressing on the bracket 24. In order to clamp a rear-facing shoulder 4 of the thickened end area of a front sole extension 5 of a cross-country ski boot 6 in the holder 2, after inserting the end area 6 moves the bracket 3 into the position shown in FIG. 6, in which the tip of the hook element 31 just engages under the rear edge 25 of the bracket. In this position, because of the dimensioning of the recess 33 described above, the guide surface 32 is in contact with the upper side of the bracket 24, ie without the application of force in An engagement of the recess 33 in the bracket 24 cannot be produced in the direction of the arrow 7. However, since the rounded guide surface 32, in conjunction with the abutment on the front edge 26 of the bracket, exerts a wedge effect under the pressing force acting in the direction of the arrow 7, the recess 33 is widened while the clamp 3 is bent, so that the bracket 24 is inserted into the recess 33 can snap. In the resulting tensioned position, which can be seen from FIG. 1, the support surface 37 of the clip extension 36 rests on the upper side 1 of the ski and thereby prevents further insertion of the bracket 24 into the recess 33. Due to the divergence of the inner surfaces of the recess 33 in the region of the hook element 31 and then on the guide surface 32 and due to the elastic pretension which presses the mentioned surfaces against the front and rear edges of the bracket 3, the clamp 3 is firmly seated in the holder 2 and engages under the shoulder 4 with the hook element 31 the sole extension 5 prevented under the bracket 24. A further pushing forward prevents the diverging legs 23 of the bracket 2, which abut the corresponding side flanks of the sole extension 5, not shown.

Von der Spitze des Hakenelements 31 aus erstreckt sich eine Hebelfläche 43 (Fig. 7) nach hinten, die auch in der Spannstellung (Fig. 1) beträchtlich über die Hinterkante 25 des Bügels 24 hinausragt. Kommt es z. B. bei einem Sturz des Skiläufers nach vorne zu einem Kontakt zwischen der Oberseite der Sohlenverlängerung 5 und dieser Hebelfläche 43 und wird dabei eine nach vorne und oben gerichtete Kraft auf die Hebelfläche 43 ausgeübt, so entsteht durch diese Kraft ein Drehmoment um eine Achse, die in der Stützfläche 37 liegt und quer zum Ski verläuft. Aufgrund dieser Kraft und infolge des Schrägverlaufes der an die Hakenspitze anschliessenden Innenfläche der Ausnehmung 33 erfolgt eine elastische Aufbiegung der Klammer 3, die zu einer Lösung der Ausnehmung 33 von dem Bügel 24 führt. Nach der Lösung nimmt die Klammer 3 die aus Fig. 7 ersichtliche Stellung ein und gibt die Sohlenverlängerung 5 dadurch frei.From the tip of the hook element 31, a lever surface 43 (FIG. 7) extends to the rear, which also projects considerably beyond the rear edge 25 of the bracket 24 in the tensioned position (FIG. 1). Is it z. B. if the skier falls forward to a contact between the top of the sole extension 5 and this lever surface 43 and a forward and upward force is exerted on the lever surface 43, this force creates a torque about an axis which lies in the support surface 37 and extends transversely to the ski. Due to this force and due to the inclined course of the inner surface of the recess 33 adjoining the hook tip, the clamp 3 is bent up elastically, which leads to a release of the recess 33 from the bracket 24. After the solution, the clamp 3 assumes the position shown in FIG. 7 and thereby releases the sole extension 5.

Durch ein weiteres Herausdrehen der Stellschraube 38 ausdem Klammerfortsatz 36 wird die Rastposition des Klammerfortsatzes 36 gegenüber der Skioberfläche nach oben verlagert, wodurch die Kontaktlinie zwischen der Bügelvorderkante 26undderzugeordneten InnenflächederAusnehmung 33 nach unten wandert. Da hierdurch bis zum Auslösen der Ausnehmung 33 aus dem Eingriff mit dem Bügel 24 ein kürzerer Weg zurückgelegt werden muss, erfolgt schon bei einer geringeren Lösekraft, die auf die Hebelfläche 43 wirkt, eine Freigabe. Somit ist die Sicherheitsauslösung der Klammer 3 individuell durch die Stellschraube 38 einstellbar.By further unscrewing the set screw 38 from the clip extension 36, the latching position of the clip extension 36 is shifted upward relative to the ski surface, as a result of which the line of contact between the front edge 26 of the bow and the associated inner surface of the recess 33 moves downward. Since this results in a shorter path until the recess 33 is released from engagement with the bracket 24, a release takes place even with a lower releasing force acting on the lever surface 43. The safety release of the clamp 3 is thus individually adjustable by means of the adjusting screw 38.

Aus Fig. 1 ist noch zu erkennen, dass durch eine nach unten gezogene Schürze 44, die sich fast bis zur Skioberseite 1 hin erstreckt, ein Schutz vor einem Eindrimen von Schnee und Schmutz in die Vertiefungen 27 geschaffen ist.It can also be seen from FIG. 1 that a downward-pulled apron 44, which extends almost to the top side 1 of the ski, provides protection against the ingress of snow and dirt into the depressions 27.
