Abstract

Ski binding as described with a retaining shell (40), which moves jointly with a pivoting part (30) and which, in order to provide a transition between a closed and open position in relation to the part, is mounted pivotally on a horizontal transverse axle (20) which resists ski-ing movements, whereby the closed position of the binding is secured by a spring locking piece (60). The pivoting part (30) carries a locking element (32) which in the closed position of the binding engages in a recess (41b) on the retaining shell (40). The latter shell (40) overlaps the front sole projection (101) of a ski-boot (100) while the locking element (32) also passes down through an opening (104) in the sole projection (101). In the open position of the binding, however, the locking element (32) is moved away from the inside of the retaining shell (40). In accordance with the invention the retaining shell (40) and pivoting part (30) are pivotally mounted on a joint transverse axle (20), which is secured to a support block (10). The combined pivoting of the retaining shell (40) and pivoting part (30) take place against an elastic element (90). The pivoting part (30) carries, on an upward-pointing protuberance (33), the locking piece (60), which in the locking position of the binding engages with the retaining shell (40). A spring (70) presses apart the retaining shell (40) and the pivoting part (30).

Description

Die Erfindung bezieht sich auf eine Kombination aus einer Skibindung und einem dazugehörenden Skischuh für einen Langlauf- oder Tourenski nach dem ersten Teil des Patentanspruches 1.The invention relates to a combination of a ski binding and an associated ski boot for a cross-country or touring ski according to the first part of patent claim 1.

Bei dieser Skibindung, die in einer älteren nicht vorveröffentlichten Europäischen Patentanmeldung (EP-A-183 000) der Anmelderin, welche einen inneren Stand der Technik bildet, beschrieben ist, sind Halteschale und Schwenkteil um eine gemeinsame Querachse gegen ein elastisches Element verschwenkbar, welche von einem am Ski montierten Lagerbock gehalten wird, wobei sich die Querachse im vorderen Bereich der beiden genannten Bauteile befindet und eine Feder Halteschale und Schwenkteil im Sinne eines Auseinanderspreizens beaufschlagt. Weiters ist der Riegel auf einem Fortsatz des Schwenkteils an einer Achse gelagert und greift in der geschlossenen Stellung der Bindung in einen mit einer Rastnut versehenen Quersteg der Halteschale ein. Diese Ausführung hat sich im allgemeinen bewährt, doch war die Halterung des Skischuhs nicht zufriedenstellend, da dieser in der Halteschale wackelte. Weiters verursachte das Vorhandensein von Schnee in der Bindung beim Einsteigen Schwierigkeiten. Außerdem war keine Maßnahme vorhanden, die verhinderte, daß während des Gehens der Riegel durch Anschlagen an Hindernisse ungewollt geöffnet wurde. Die zum Auseinanderspreizen von Halteschale und Schwenkteil dienende Feder ist in ihren Bemessungen und daher auch in ihrer Wirkung konstruktionsbedingt beschränkt. Beim Einsteigen konnte es aufgrund ihrer geringen Schließkraft dazu kommen, daß die Halteschale nach unten schwenkte, noch bevor der Skischuh fest in der Halteschale saß.In this ski binding, which is described in an older, unpublished European patent application (EP-A-183 000) by the applicant, which forms an internal state of the art, the holding shell and the pivoting part can be pivoted about a common transverse axis against an elastic element, which by a bearing block mounted on the ski is held, the transverse axis being in the front region of the two components mentioned and a spring holding shell and pivoting part acting in the sense of a spreading apart. Furthermore, the bolt is mounted on an extension of the swivel part on an axis and, in the closed position of the binding, engages in a transverse web of the holding shell provided with a locking groove. This version has proven itself in general, but the mounting of the ski boot was unsatisfactory because it wobbled in the holding shell. Furthermore, the presence of snow in the binding caused difficulties when getting in. In addition, there was no measure to prevent the bolt from being opened unintentionally by hitting obstacles while walking. The dimensions of the spring used to spread the holding shell and the swivel part are limited in terms of their design and therefore also in their effect due to the design. When getting in, the low closing force could cause the holding cup to swing down even before the ski boot was firmly seated in the holding cup.

Die Erfindung hat sich mehrere Aufgaben gesetzt, um die Nachteile dieser älteren Lösung zu beheben, die im folgenden behandelt werden. Als erste Aufgabe soll die Halterung des Skischuhs in der Halteschale verbessert werden, gegebenenfalls auch wenn Schnee in der Bindung ist.The invention has set itself several objects to overcome the disadvantages of this older solution, which are discussed below. The first task is to improve the retention of the ski boot in the holding shell, if necessary even when there is snow in the binding.

Erreicht wird dieses Ziel erfindungsgemäß durch die im Anspruch 1 enthaltenen kennzeichnenden Merkmale.This aim is achieved according to the invention by the characterizing features contained in claim 1.

Durch die erfindungsgemäßen Maßnahmen nach den kennzeichnenden Merkmalen des Anspruches 1 wird eine gute Halterung des Skischuhs in der Halteschale gewährleistet.The measures according to the invention according to the characterizing features of claim 1 ensure good retention of the ski boot in the holding shell.

Durch die Merkmale des Anspruches 2 wird der optimale Winkel der Anlageflächen mit etwa 45° festgelegt, so daß einerseits bei Schneeauflage an den Anlageflächen die Längsverschiebung des Skischuhs nicht zu groß wird, was bei kleineren Winkeln der Fall wäre und damit zu einer großen Belastung des Verriegelungszapfens bzw. des Einhakelementes führen würde, und andererseits dem Skischuh durch die Anlageflächen noch genügend seitliche Abstützung geboten wird, was bei größeren Winkeln nicht mehr der Fall wäre. Durch diese Maßnahmen wird weiters die Bindung gegen Toleranzen weniger empfindlich.Due to the features of claim 2, the optimal angle of the contact surfaces is set at approximately 45 °, so that on the one hand the longitudinal displacement of the ski boot does not become too great when there is snow on the contact surfaces, which would be the case at smaller angles and thus to a large load on the locking pin or the hooking element would lead, and on the other hand the ski boot is still provided with sufficient lateral support by the contact surfaces, which would no longer be the case at larger angles. These measures also make the bond less sensitive to tolerances.

Durch Zusammenwirken der Merkmale des Anspruches 3 wird der vordere Bereich des Skischuhs in besonders vorteilhafter Weise gestaltet.By interacting the features of claim 3, the front region of the ski boot is designed in a particularly advantageous manner.

Die Merkmale des Anspruches 4 ermöglichen eine besonders gute Passung des Einhakelementes an den Verriegelungszapfen.The features of claim 4 allow a particularly good fit of the hooking element on the locking pin.

Die Merkmale der Ansprüche 5 bzw. 6 stellen andere vorteilhafte Ausgestaltungen des Einhakelementes dar.The features of claims 5 and 6 represent other advantageous configurations of the hooking element.

Die Merkmale des Anspruches 7 bestimmen die Abstützflächen am Skischuh, mit denen sich dieser an den Anlageflächen der Halteschale abstützt. Ebenso bestimmen die Merkmale die Führungsflächen des Skischuhs und zwar, daß die untere Führungsfläche des Skischuhs am Boden der Halteschale aufliegt und die obere Führungsfläche an den Führungsleisten der Halteschale von unten anliegt.The features of claim 7 determine the support surfaces on the ski boot with which it is supported on the contact surfaces of the holding shell. The features likewise determine the guide surfaces of the ski shoe, namely that the lower guide surface of the ski shoe rests on the bottom of the holding shell and the upper guide surface rests on the guide strips of the holding shell from below.

Die Merkmale der Ansprüche 8 und 9 beschreiben verschiedene Durchbrechungen in der Halteschale, durch welche sichergestellt wird, daß beim Einsteigen in der Bindung befindlicher Schnee ausgepreßt wird. Im Zusammenwirken mit den Merkmalen der Ansprüche 4 und 5 kommt es zu einer Hinführung des in der Bindung befindlichen Schnees zu den Durchbrechungen der Halteschale.The features of claims 8 and 9 describe various openings in the holding shell, by which it is ensured that snow in the binding is pressed out when boarding. In cooperation with the features of claims 4 and 5, the snow in the binding is led to the openings in the holding shell.

Als zweite Aufgabe soll der Riegel eine zusätzliche Sicherung erhalten, ohne die Anzahl der Bauteile zu erhöhen.The second task is to provide the latch with additional security without increasing the number of components.

Erreicht wird dieses Ziel durch die im Anspruch 10 enthaltenen kennzeichnenden Merkmale.This goal is achieved by the characterizing features contained in claim 10.

Durch die Maßnahmen nach den kennzeichnenden Merkmalen des Anspruches 10 weist der Riegel eine weitere Sperre auf, so daß eine ungewollte Entriegelung während des Gehens durch Schläge und Stöße nicht möglich ist.By the measures according to the characterizing features of claim 10, the bolt has a further lock, so that an unwanted unlocking while walking is not possible due to blows and bumps.

Als dritte Aufgabe soll gewährleistet werden, daß das Einsteigen in die Bindung immer unter kontrollierten Verhältnissen vor sich geht.The third task is to ensure that getting into the binding always takes place under controlled conditions.

Erreicht wird dieses Ziel durch die im Anspruch 11 enthaltenen kennzeichnenden Merkmale.This goal is achieved by the characterizing features contained in claim 11.

Durch die Maßnahmen nach den kennzeichnenden Merkmalen des Anpruches 11 wird eine Erhöhung der Schließkraft der Halteschale beim Einsteigen in die Bindung ohne zusätzliche Teile und ohne Verstärkung der zur Verwendung gelangenden Federn erreicht, um das Einsteigen in die Bindung immer unter kontrollierten Verhältnissen zu gewährleisten.Through the measures according to the characterizing features of claim 11, an increase in the closing force of the holding shell when entering the binding is achieved without additional parts and without reinforcing the springs to be used, in order to ensure that entry into the binding always takes place under controlled conditions.

Die Merkmale des Anspruches 12 bewirken, daß der Schwenkwinkel des Riegels beim Schließen der Bindung gleich dem minimalen Schwenkwinkel beim Öffnen derselben ist.The features of claim 12 cause that the pivot angle of the bolt when closing the binding is equal to the minimum pivot angle when opening the same.

Durch die Ausgestaltung nach den Merkmalen des Anspruches 13 wird die Lage des Riegels und der Halteschale zueinander in der geöffenten Stellung der Bindung festgelegt.Due to the configuration according to the features of claim 13, the position of the bolt and the holding shell relative to one another is determined in the open position of the binding.

Bei allen vorangehend beschriebenen Ausgestaltungen muß der Riegel während des ganzen Aussteigvorganges vom Benützer mit dem Skistock in derjenigen Stellung gehalten werden, in der er den Schwenkteil freigibt.In all of the configurations described above, the bolt must be held by the user with the ski stick in the position in which he releases the pivoting part during the entire alighting process.

Die Erfindung setzt sich daher die vierte Aufgabe, auch diesen Nachteil zu beseitigen und eine Skibindung zu schaffen, bei der der Benützer die Möglichkeit hat, sich während des Aussteigvorganges mit beiden Skistöcken in der Loipe abzustützen.The invention therefore has the fourth object to eliminate this disadvantage and one To create ski bindings where the user has the opportunity to support himself with both ski poles in the cross-country ski trail during the alighting process.

Ausgehend von einer Skibindung gemäß dem ersten Teil des Anspruches 1 wird diese Aufgabe durch die Merkmale des kennzeichnenden Teiles des Anspruches 14 gelöst.Starting from a ski binding according to the first part of claim 1, this object is achieved by the features of the characterizing part of claim 14.

Eine Skibindung für den Langlauf gemäß der DE-OS 34 05 861 besitzt eine unter der Skischuhsohle angeordnete Basisplatte, welche sich zur Skispitze hin in zwei Wangen fortsetzt, zwischen denen ein Griffhebel, der unter dem Einfluß einer Schenkelfeder steht, auf einer Querachse schwenkbar angeordnet ist. Die Schenkelfeder drückt den Griffhebel gegen einen Niederhalter für die Skischuhsohle, der um eine zwischen den Wangen angeordnete weitere Querachse, auf der auch ein Trittsporn gelagert ist, verschwenkt werden kann. Letzterer greift mit seinem Ende in eine Ausnehmung der Skischuhsohle von unten ein.A ski binding for cross-country skiing according to DE-OS 34 05 861 has a base plate arranged under the ski boot sole, which continues towards the tip of the ski in two cheeks, between which a handle lever, which is under the influence of a leg spring, is pivotably arranged on a transverse axis . The leg spring presses the handle lever against a hold-down device for the sole of the ski boot, which can be pivoted about a further transverse axis arranged between the cheeks, on which a step spur is also mounted. The end of the latter engages in a recess in the sole of the ski boot from below.

In der Einsteigstellung der Bindung wird der Niederhalter vom Griffhebel dadurch festgehalten, daß eine Führungskurve des Griffhebels eine Nocke des Niederhalters übergreift. Wenn die Sohle des Skischuhs sich beim Einstieg der Basisplatte nähert, wandert die Nocke entlang der Führungskurve, und bei Überschreiten des Kulminationspunktes wird der Niederhalter in die Sperrlage verschwenkt.In the entry position of the binding, the hold-down is held by the handle lever in that a guide curve of the handle lever engages over a cam of the hold-down. When the sole of the ski shoe approaches the base plate when entering, the cam moves along the guide curve, and when the culmination point is exceeded, the hold-down device is pivoted into the locked position.

Diese Bindung hat den Nachteil, daß die Schrittbewegung des Skiläufers nur durch die Elastizität der Sohle des Skischuhs, nicht aber durch eine Gelenklasche in der Bindung herbeigeführt wird. Diese bekannte Lösung unterscheidet sich daher gattungsmäßig vom Gegenstand der Erfindung.This binding has the disadvantage that the step movement of the skier is brought about only by the elasticity of the sole of the ski boot, but not by an articulated flap in the binding. This known solution therefore differs generically from the object of the invention.

Selbstverständlich bieten sich für die praktische Ausgestaltung des Rastorgans verschiedene Lösungen an. Als besonders zweckmäßig hat sich jedoch die Konstruktion nach Anspruch 15 erwiesen. Bei dieser Konstruktion wird zur Herbeiführung des gewünschten Effektes nur eine zusätzliche Schenkelfeder benötigt.Of course, there are various solutions for the practical design of the locking element. However, the construction according to claim 15 has proven to be particularly useful. With this construction, only an additional leg spring is required to achieve the desired effect.

An sich wäre es möglich, zur Festlegung des in die Nut des Riegels ragenden Schenkels der Schenkelfeder, die relativ schwach bemessen ist, eine Abflachung im Boden der bogenförmigen Nut vorzusehen, an der das Federende durch Reibung festgehalten wird. Diese Ausgestaltung könnte aber mitunter zu einem unbeabsichtigten Verschwenken des Riegels Anlaß geben. Dies wird durch die Maßnahme des Anspruches 16 verhindert.As such, it would be possible to provide a flattened portion in the bottom of the arcuate groove to fix the leg of the leg spring projecting into the groove of the bolt, which leg is relatively weak, to which the spring end is held by friction. This configuration could sometimes give rise to an unintentional pivoting of the bolt. This is prevented by the measure of claim 16.

Durch den Gegenstand des Anspruches 17 wird die Gefahr beseitigt, daß sich das Ende des Schenkels der Schenkelfeder im Riegel verspießt.The subject matter of claim 17 eliminates the risk of the end of the leg of the leg spring being spiked in the bolt.

Durch die Maßnahme des Anspruches 18 wird es möglich, daß der Riegel selbsttägig in seine Raststellung zurückkehrt, sobald das Ende des Schenkels von dem Quersteg der Halteschale über den Rastvorsprung der Nut gedrückt worden ist.The measure of claim 18 makes it possible for the bolt to automatically return to its latching position as soon as the end of the leg has been pressed by the crosspiece of the holding shell over the latching projection of the groove.

Durch die Merkmale des Anspruches 19 wird die Betriebssicherheit der Skibindung erhöht, da die erforderliche Federkraft auf zwei Hälften eines Bügels aufgeteilt wird, wodurch die Gefahr des Knickens des belasteten Schenkels der Schenkelfeder erheblich verringert wird.Due to the features of claim 19, the operational reliability of the ski binding is increased, since the required spring force is divided into two halves of a bracket, which considerably reduces the risk of the loaded leg of the leg spring bending.

Die erste Ausführungsform nach den Fig. 1 bis 7 und 10 bis 12 stellt eine Skibindung für einen Langlauf- oder Tourenski 1 und einen dazugehörigen Skischuh 100 dar. Auf der Oberseite eines Ski 1 ist mittels angedeuteter Schrauben 2 ein Lagerbock 10 montiert. Er besteht aus einer Grundplatte 11 mit zwei Wänden 12, die am vorderen, der Skispitze zugewandten Ende der Grundplatte 11 beginnen und etwa bis zur Mitte der Grundplatte 11 führen und im letzteren Bereich eine Querachse 20 tragen. Die Grundplatte 11 trägt an ihrem vorderen Ende eine Rippe 13 und an ihrem hinteren Ende eine Auflagefläche 14, in der die Schrauben 2 versenkt sind.The first embodiment according to FIGS. 1 to 7 and 10 to 12 represents a ski binding for a cross-country or touring ski 1 and an associated ski boot 100. A bearing block 10 is mounted on the top of a ski 1 by means of indicated screws 2. It consists of a base plate 11 with two walls 12, which begin at the front end of the base plate 11 facing the ski tip and lead approximately to the middle of the base plate 11 and carry a transverse axis 20 in the latter area. The base plate 11 carries at its front end a rib 13 and at its rear end a support surface 14 in which the screws 2 are countersunk.

Auf der Querachse 20 ist ein Schwenkteil 30 angebracht, der mit seinem Boden 31 an der Auflagefläche 14 des Lagerbocks 10 aufliegt. Der Boden 31 besitzt an seiner dem Ski 1 abgewandten Seite von der Längsachse der Bindung schräg nach außen abfallende Flächen 31 a. Am von der Querachse 20 abgelegenen Ende trägt der Boden 31 einen Verriegelungszapfen 32 oder -balken. An der Querachse 20 ist auch eine Halteschale 40 angebracht, deren Bodenfläche 41 eine Freistellung 41b für den Verriegelungszapfen 32 und weitere Durchbrechungen 41a (Fig. 6) aufweist. An die Seitenwände 42 der Halteschale 40, die in ihrem vorderen Teil mit einem Quersteg 43, der eine Rastnut 43a trägt, verbunden sind und in ihrem hinteren von der Querachse 20 abgelegenen Bereich Anlageflächen 44 aufweisen, schließen oben Führungsleisten 45 an.On the transverse axis 20, a pivoting part 30 is attached, with its bottom 31 on the Support surface 14 of the bearing block 10 rests. The bottom 31 has on its side facing away from the ski 1 from the longitudinal axis of the binding slopes 31 a sloping outwards. At the end remote from the transverse axis 20, the bottom 31 carries a locking pin 32 or bar. A holding shell 40 is also attached to the transverse axis 20, the bottom surface 41 of which has an exemption 41b for the locking pin 32 and further openings 41a (FIG. 6). Guide strips 45 are connected at the top to the side walls 42 of the holding shell 40, which are connected in their front part to a transverse web 43 which carries a latching groove 43a and in their rear region remote from the transverse axis 20.

Ein von der Querachse 20 nach oben ragender Fortsatz 33 des Schwenkteils 30 trägt an seinem oberen Ende eine Achse 50, an der ein als zweiarmiger Hebel ausgebildeter Riegel 60 angelenkt ist, der an seinem der Halteschale 40 zugewandten Arm einen hohlkehlenförmigen Anschlag 63 (Fig. 10-12) und eine Rastnase 61 und an der dem Ski 1 abgewandten Seite seines zweiten Armes eine Vertiefung 62 trägt.An extension 33 of the pivoting part 30, which projects upwards from the transverse axis 20, carries at its upper end an axis 50 to which a bolt 60 designed as a two-armed lever is articulated, which on its arm facing the holding shell 40 has a groove-shaped stop 63 (FIG. 10 -12) and a detent 61 and on the side of the ski 1 facing away from its second arm carries a recess 62.

Für eine Feder 70 um die Querachse 20, die Halteschale 40 und Schwenkteil 30 im Sinne eines Auseinanderspreizens belastet, sind im Boden 31 des Schwenkteils 30 entsprechende Hohlräume 31b vorgesehen. Eine Riegelfeder 80 um die Achse 50 beaufschlagt den Riegel 60 in Schließrichtung zur Halteschale 40.Corresponding cavities 31b are provided in the bottom 31 of the pivoting part 30 for a spring 70 about the transverse axis 20, which holds the holding shell 40 and the pivoting part 30 in the sense of spreading apart. A locking spring 80 around the axis 50 acts on the locking bar 60 in the closing direction to the holding shell 40.

Im vorderen Teil des Lagerbocks 10 wird ein elastisches Element 90 derart eingesetzt, daß es mit seiner Ausnehmung 91 über der Rippe 13 der Grundplatte 11 zu liegen kommt und sich dabei mit seinem der Rippe 13 abgewandten Teil am Schwenkteil 30 abstützt. Das elastische Element 90 weist eine Bohrung 92 auf, um die Schraube 2 bei der Montage der Bindung am Ski 1 ungehindert einsetzen zu können.In the front part of the bearing block 10, an elastic element 90 is used in such a way that its recess 91 comes to rest over the rib 13 of the base plate 11 and is supported on the pivot part 30 with its part facing away from the rib 13. The elastic element 90 has a bore 92 in order to be able to use the screw 2 unhindered when mounting the binding on the ski 1.

Der in die Bindung einzusetzende Skischuh 100 nach Fig. 7 weist in seinem vorderen Bereich eine Sohlenverlängerung 101 auf, die aus Fortsätzen 101a und einem darin mit seinen Schenkeln 102a eingegossenen U-förmigen Einhakelement 102 gebildet ist. Zwischen dem Einhakelement 102 und der Stirnseite 103 der Sohle wird eine Öffnung 104 gebildet. Von der Seite betrachtet weist der vordere Bereich der Sohle keilförmig zulaufende Führungsflächen 105a, 105b auf, wobei die untere Führungsfläche 105b dazu bestimmt ist, auf der Bodenfläche 41 der Halteschale 40 aufzuliegen. Der Winkel zwischen der oberen 105a und unteren Führungsfläche 105b ist der gleiche wie der Winkel zwischen der Bodenfläche 41 und den Führungsleisten 45 der Halteschale 40, da bei in die Bindung eingesetztem Skischuh 100 die obere Führungsfläche 105a von unten an den Führungsleisten 45 der Halteschale 40 anliegen soll. Der mit den Führungsflächen 105a, 105b versehene Sohlenbereich weist Abstützflächen 106 auf, die bei eingesetztem Skischuh 100 parallel zu den Anlageflächen 44 der Halteschale 40 an diesen anliegen.The ski boot 100 according to FIG. 7 to be inserted into the binding has in its front area a sole extension 101 which is formed from extensions 101a and a U-shaped hooking element 102 cast into it with its legs 102a. An opening 104 is formed between the hooking element 102 and the end face 103 of the sole. Viewed from the side, the front region of the sole has wedge-shaped guide surfaces 105a, 105b, the lower guide surface 105b being intended to rest on the bottom surface 41 of the holding shell 40. The angle between the upper 105a and lower guide surface 105b is the same as the angle between the bottom surface 41 and the guide strips 45 of the holding shell 40, since when the ski boot 100 is inserted into the binding, the upper guide surface 105a abuts against the guide strips 45 of the holding shell 40 from below should. The sole area provided with the guide surfaces 105a, 105b has support surfaces 106 which, when the ski boot 100 is inserted, lie parallel to the contact surfaces 44 of the holding shell 40.

In einer zweiten Ausführungsform nach den Fig. 8 und 9 befinden sich in den Seitenwänden 42' der Halteschale 40' Durchbrechungen 42'a, welche sich nach außen erweitern. Der zu dieser Ausführungsform zugehörige Skischuh 100' weist auf der Außenfläche des mit Sohlenmaterial umgebenen Einhakelementes 102' abgeschrägte Flächen 102'c auf.In a second embodiment according to FIGS. 8 and 9 there are openings 42'a in the side walls 42 'of the holding shell 40' which widen outwards. The ski boot 100 'belonging to this embodiment has beveled surfaces 102'c on the outer surface of the hooking element 102' surrounded by sole material.

Beim Einsteigen in die Bindung nach Fig. 1 wird der Skischuh 100 mit seinen Führungsflächen 105a, 105b in die Halteschale 40 schräg von oben eingeführt, bis er mit seinem Einhakelement 102 an der Rastnase 61 des Riegels 60 anliegt, und dann niedergetreten, wobei die Halteschale 40 gegen die Kraft der Feder 70 und teilweise gegen die der Riegelfeder 80 hinuntergeschwenkt wird. Dabei durchdringt der Verriegelungszapfen 32 die Öffnung 104 in der Sohlenverlängerung 101 des Skischuhs 100 von unten. Die Schräge des linearen Abschnittes 32a des Verriegelungszapfens 32 dient in der ersten Phase des Niedertretens der Halteschale 40 zur Erleichterung des Einfädelns des Verriegelungszapfens 32 in die Öffnung 104, bis der Skischuh 100 mit seinen Abstützflächen 106 an den Anlageflächen 44 der Halteschale 40 anliegt. In der zweiten Phase bewegt sich das Einhakelement 102 weiterhin entlang des linearen Abschnittes 32a, jedoch unter wachsender Zugspannung. In der dritten Phase des Niedertretens, ab dem Übergangspunkt 32c vom linearen Abschnitt 32a zum Kreisbogenabschnitt 32b bleibt die Zugspannung, während sich das Einhakelement 102 entlang dem Kreisbogenabschnitt 32b bis zu seiner endgültigen Lage bewegt, konstant, da der Kreisbogenabschnitt 32b sein Zentrum in der Querachse 20 hat. Gleichzeitig gleitet der Quersteg 43 an der Innenseite der Rastnase 61 hinunter, indem er diese in Öffnungsrichtung beaufschlagt (Fig. 10-11), bis die Rastnase 61 in seiner Rastnut 43a einrastet und damit die Stellung fixiert. Das Einsteigen in die Bindung erfolgt gegen eine gegenüber der als Aufstellfeder konzipierten Feder 70 erhöhte Einstiegskraft, indem die Riegelfeder 80 beim Verschwenken der Halteschale 40 zusätzlich beaufschlagt wird. Diese Lösung ergibt sich einfach durch konstruktive Maßnahmen bei der Ausgestaltung von Riegel 60 und Quersteg 43 der Halteschale 40, wodurch beim Einsteigen in die Bindung der Schwenkwinkel (a) des Riegels 60 vergrößert und damit die Riegelfeder 80 stärker komprimiert wird. Durch das Einsteigen gegen die erhöhte Federkraft wird ein vorzeitiges, unkontrolliertes Schließen der Bindung verhindert, solange der Skischuh 100 nicht fest in der Halteschale 40 sitzt. In der Bindung befindlicher Schnee wird beim Einsteigvorgang in der ersten Ausführungsform durch die Durchbrechungen 41a in der Bodenfläche 41 der Halteschale 40 ausgepreßt. Bei der zweiten Ausführungsform wird der Schnee durch die abgeschrägten Flächen 102'c am Einhakelement 102' zu den Durchbrechungen 42'a in den Seitenwänden 42' der Halteschale 40' hingeführt und durch diese ausgepreßt. Außerdem wird zwischen Schwenkteil 30 und Halteschale 40 befindlicher Schnee durch die schrägen Flächen 31a am Boden 31 des Schwenkteils 30 nach außen geleitet.1, the ski boot 100 is inserted with its guide surfaces 105a, 105b into the holding shell 40 obliquely from above until it engages with the hooking element 102 on the locking lug 61 of the latch 60, and then depressed, the holding shell 40 against the force of the spring 70 and partially against which the locking spring 80 is pivoted down. The locking pin 32 penetrates the opening 104 in the sole extension 101 of the ski boot 100 from below. The slope of the linear section 32a of the locking pin 32 serves in the first phase of the depression of the holding shell 40 to facilitate the threading of the locking pin 32 into the opening 104 until the ski boot 100 rests with its support surfaces 106 on the contact surfaces 44 of the holding shell 40. In the second phase, the hooking element 102 continues to move along the linear section 32a, but with increasing tension. In the third phase of depression, from the transition point 32c from the linear section 32a to the circular arc section 32b, the tension remains constant as the hooking element 102 moves along the circular arc section 32b to its final position, since the circular arc section 32b is centered in the transverse axis 20 Has. At the same time, the crosspiece 43 slides down on the inside of the locking lug 61 by applying it in the opening direction (FIGS. 10-11) until the locking lug 61 engages in its locking groove 43a and thus fixes the position. The entry into the binding takes place against an entry force which is higher than that of the spring 70 designed as a setting spring, in that the locking spring 80 is additionally acted upon when the holding shell 40 is pivoted. This solution is obtained simply by constructive measures in the design of the latch 60 and the crosspiece 43 of the holding shell 40, as a result of which the pivoting angle (a) of the latch 60 is enlarged when entering the binding and the latch spring 80 is thus compressed more. Climbing in against the increased spring force prevents premature, uncontrolled closing of the binding as long as the ski boot 100 is not firmly seated in the holding shell 40. Snow in the binding is pressed out during the boarding process in the first embodiment through the openings 41a in the bottom surface 41 of the holding shell 40. In the second embodiment, the snow is guided through the beveled surfaces 102'c on the hooking element 102 'to the openings 42'a in the side walls 42' of the holding shell 40 'and pressed out by the latter. In addition, between pivoting part 30 and holding shell 40 is located Snow is guided outwards through the inclined surfaces 31a at the bottom 31 of the swivel part 30.

In vollständig zum Ski 1 abgesenkter Position der Halteschale 40, wenn diese auf der Auflagefläche 14 der Grundplatte 11 aufliegt, wie dies in der Fahrtstellung nach Fig. 2 der Fall ist, hat das Einhakelement 102 seine tiefste Position im Kreisbogenabschnitt 32b des Verriegelungszapfens 32 angenommen, während die Rastnase 61 des Riegels 60 an der in Schließrichtung des Riegels 60 liegenden Wand 43b anliegt. In dieser Stellung, die auch beim Stehen eingenommen wird, kann der Riegel 60 durch Einsatz einer Skistockspitze in seine Vertiefung 62 und Druckausübung gegen die Kraft der Riegelfeder 80 geöffnet werden, wobei der Skischuh 100 durch Hochheben aus dem Eingriff des Verriegelungszapfens 32 kommt und anschließend aus der Halteschale 40 gezogen werden kann.In the position of the holding shell 40 completely lowered to the ski 1, when it rests on the support surface 14 of the base plate 11, as is the case in the driving position according to FIG. 2, the hooking element 102 has assumed its lowest position in the circular arc section 32b of the locking pin 32, while the locking lug 61 of the latch 60 bears against the wall 43b lying in the closing direction of the latch 60. In this position, which is also assumed when standing, the latch 60 can be opened by using a ski stick tip in its recess 62 and exerting pressure against the force of the latch spring 80, the ski boot 100 coming out of the engagement of the locking pin 32 and then out the holding shell 40 can be pulled.

Fig. 3 zeigt die Bindung in geschlossener Stellung, jedoch ohne Belastung durch den Skischuh 100. Aufgrund der Beaufschlagung durch die Feder 70 hebt sich die Halteschale 40 solange, bis die Rastnase 61 des Riegels 60 vollständig in der Rastnut 43a liegt. In dieser Position, von welcher in Fig. 3a der Eingriff der Rastnase 61 des Riegels 60 im Quersteg 43 der Halteschale 40 in vergrößertem Maßstab dargestellt ist, kann der Riegel 60 nicht geöffnet werden. In Fig. 3a ist der Weg der Rastnase 61 bei Verschwenkung des Riegels 60 in Öffnungsrichtung in strichpunktierter Linie als Kreisbogen 200a um die Achse 50 eingezeichnet. An dieser Verschwenkung wird der Riegel 60 jedoch durch einen erhabenen Bereich 43c der in Öffnungsrichtung des Riegels 60 liegenden Wand des Quersteges 43 gehindert, welcher somit eine zusätzliche Sicherung für den Riegel 60 darstellt. Wenn ein Skischuh 100 in die Bindung eingesetzt ist, durchläuft er die Position nach Fig. 3 in der ersten phase des Gehens. Durch die Relativbewegung der Halteschale 40 gegenüber dem Schwenkteil 30 liegt das Einhakelement 102 des Skischuhs 100 in dieser Position im oberen Bereich des Kreisbogenabschnittes 32b des Verriegelungszapfens 32. Bei weiterem Anheben des Skischuhs 100 nach Fig. 4 bleibt die Raststellung zwischen Riegel 60 und Quersteg 43 der Halteschale 40 einerseits und die Lage des Einhakelementes 102 im Kreisbogenabschnitt 32b des Verriegelungszapfens 32 andererseits erhalten, wodurch Halteschale 40 und Schwenkteil 30 eine Einheit bilden und gemeinsam gegen die Kraft des elastischen Elementes 90 entgegen dem Uhrzeigersinn verschwenken. Sich während des Gehens in der Bindung ansammelnder Schnee wird durch schräge Schneeauspreßflächen 15, 31c, die sowohl auf der Grundplatte 11, wie auch an der Unterseite des Schwenkteils 30 ausgebildet sind, aus der Bindung gepreßt.Fig. 3 shows the binding in the closed position, but without stress from the ski boot 100. Due to the action of the spring 70, the holding shell 40 lifts until the latch 61 of the latch 60 lies completely in the latch groove 43a. In this position, from which the engagement of the locking lug 61 of the bolt 60 in the crosspiece 43 of the holding shell 40 is shown on an enlarged scale in FIG. 3a, the bolt 60 cannot be opened. In Fig. 3a, the path of the latch 61 when pivoting the bolt 60 in the opening direction is drawn in a dash-dotted line as a circular arc 200a about the axis 50. However, the bolt 60 is prevented from this pivoting by a raised region 43c of the wall of the crossbar 43 lying in the opening direction of the bolt 60, which thus represents an additional safeguard for the bolt 60. When a ski boot 100 is inserted into the binding, it passes through the position according to FIG. 3 in the first phase of walking. As a result of the relative movement of the holding shell 40 relative to the swivel part 30, the hooking element 102 of the ski boot 100 lies in this position in the upper region of the circular arc section 32b of the locking pin 32. When the ski boot 100 according to FIG. 4 is raised further, the locking position between the latch 60 and the crossbar 43 remains Retaining shell 40 on the one hand and the position of the hooking element 102 in the circular arc section 32b of the locking pin 32 on the other hand, whereby the retaining shell 40 and pivoting part 30 form a unit and jointly pivot counterclockwise against the force of the elastic element 90. Snow accumulating in the binding during walking is pressed out of the binding by oblique snow-pressing surfaces 15, 31c, which are formed both on the base plate 11 and on the underside of the swivel part 30.

Unter anderem ist erfindungswesentlich, daß der Riegel 60 und der Quersteg 43 der Halteschale 40 so aufeinander abgestimmt sind, daß der Riegel 60 in offener und geschlossener Stellung der Bindung eine genau definierte Lage einnimmt. Diese Lage wird durch die Position von Riegel 60 und Halteschale 40 zueinander festgelegt, welche sich in Offenstellung der Bindung durch Anliegen einer Überhöhung 43d des Quersteges 43 an dem hohlkehlenförmig gestalteten Anschlag 63 des Riegels 60 und in geschlossener Stellung durch Anliegen der Rastnase 61 des Riegels 60 auf der in Schließrichtung des Riegels 60 liegenden Wand 43b der Rastnut 43a des Quersteges 43 ergibt.Among other things, it is essential to the invention that the bolt 60 and the crosspiece 43 of the holding shell 40 are matched to one another in such a way that the bolt 60 assumes a precisely defined position in the open and closed position of the binding. This position is determined by the position of the latch 60 and the holding shell 40 relative to one another, which in the open position of the binding is due to the presence of an elevation 43d of the crosspiece 43 on the flute-shaped stop 63 of the latch 60 and in the closed position by the engagement of the latch 61 of the latch 60 on the wall 43b lying in the closing direction of the latch 60 results in the locking groove 43a of the cross piece 43.

Im Ausführungsbeispiel nach den Fig. 10 bis 12 sind der Riegel 60 und der Quersteg 43 der Halteschale 40 so aufeinander abgestimmt, daß die Lage des Riegels 60 in offener und geschlossener Stellung der Bindung dieselbe ist.In the exemplary embodiment according to FIGS. 10 to 12, the bolt 60 and the crosspiece 43 of the holding shell 40 are matched to one another in such a way that the position of the bolt 60 is the same in the open and closed position of the binding.

Sowohl beim Öffnen wie auch beim Schließen der Bindung gleiten die Überhöhung 43d des Quersteges 43 der Halteschale 40 und die Rastnase 61 des Riegels 60 aneinander vorbei, wobei die Halteschale 40 eine Schwenkbewegung in einer Richtung und der Riegel 60 eine Schaukelbewegung durchführt, bei der er eine maximale Verschwenkung erreicht, um dann wieder in seine Ausgangslage zurückzukehren. Die Lage der maximalen Verschwenkung ist durch den Schnittpunkt 200 zweier Kurven gegeben, und zwar durch den Kreisbogen 200a, den die Rastnase 61 um die Achse 50, und den Kreisbogen 200b, den die Überhöhung 43d des Quersteges 43 um die Querachse 20 beschreibt. Da beim Ausführungsbeispiel die Stellung des Riegels 60 bei geschlossener und offener Bindung dieselbe ist und der Schnittpunkt 200 eine feste Lage hat, ist der Schwenkwinkel (a) des Riegels 60 beim Schließen der Bindung identisch mit dem minimalen Schwenkwinkel (ß) bei der Öffnung der Bindung. In Fig. 11 wird die Verschwenkung des Riegels 60 und der Halteschale 40 unter Weglassung aller anderen Bauteile gezeigt, wobei von der Halteschale 40 nur der Quersteg 43 dargestellt ist. Die Lage von Riegel 60 und Halteschale 40 in Offenstellung der Bindung wird in vollen Linien veranschaulicht. Beim Schließen der Bindung, d.h. Niederschwenken der Halteschale 40, gleitet der Quersteg 43 mit seiner Uberhöhung 43d an der Innenseite der Rastnase 61 hinunter, wobei er den Riegel 60 in Öffnungsrichtung beaufschlagt, bis dieser die Lage seiner maximalen Verschwenkung erreicht, die in Fig. 11 mit strichlierten Linien festgehalten ist. Nach Überschreiten dieser Stellung verschwenkt die Halteschale 40 weiter und der Riegel 60 legt sich mit seiner Rastnase 61 an der in Schließrichtung des Riegels 60 liegenden Wand 43b des Quersteges 43 an, wobei der Riegel 60 wieder in seine Ausgangsposition zurückgekehrt ist. Die Lage des Quersteges 43 bei geschlossener Bindung ist in Fig. 11 mit punktierter Linie eingezeichnet.Both when opening and when closing the binding, the cant 43d of the crosspiece 43 of the holding shell 40 and the latch 61 of the bolt 60 slide past one another, the holding shell 40 pivoting in one direction and the bolt 60 performing a rocking movement, in which it performs a maximum pivoting reached to then return to its original position. The position of the maximum pivoting is given by the intersection 200 of two curves, namely by the circular arc 200a, which the locking lug 61 about the axis 50, and the circular arc 200b, which the elevation 43d of the crosspiece 43 describes about the transverse axis 20. Since, in the exemplary embodiment, the position of the latch 60 is the same when the binding is closed and open and the intersection 200 has a fixed position, the pivoting angle (a) of the latch 60 when closing the binding is identical to the minimum pivoting angle (β) when the binding is opened . FIG. 11 shows the pivoting of the bolt 60 and the holding shell 40 with the omission of all other components, only the crosspiece 43 of the holding shell 40 being shown. The position of bolt 60 and holding shell 40 in the open position of the binding is illustrated in full lines. When closing the binding, i.e. Swiveling down the holding shell 40, the crossbar 43 slides down with its elevation 43d on the inside of the locking lug 61, whereby it acts on the bolt 60 in the opening direction until it reaches the position of its maximum pivoting, which is shown in FIG. 11 with broken lines. After this position has been exceeded, the holding shell 40 pivots further and the latch 60 rests with its catch 61 on the wall 43b of the transverse web 43 lying in the closing direction of the latch 60, the latch 60 having returned to its starting position. The position of the crosspiece 43 when the binding is closed is shown in FIG. 11 with a dotted line.

Die in den Fig. 13 bis 20 dargestellte Skibindung entspricht, bis auf die Ausgestaltung des Riegels und dessen Rastorgans, dem Aufbau nach dem bisher Beschriebenen. Aus diesem Grund sind die anderen Bauteile der Skibindung mit identischen Bezugsziffern versehen, selbst dann, wenn sie sich von den vorangehend gezeigten Ausgestaltungen geringfügig unterscheiden. Der Riegel und dessen Rastorgan sind zum besseren Unterschied mit Ziffern über 300 bezeichnet worden.The ski binding shown in FIGS. 13 to 20 corresponds, except for the design of the bar and its locking member, to the structure according to what has been described so far. For this reason, the other components of the ski binding are provided with identical reference numbers, even if they differ from the embodiment shown above differ slightly. For better distinction, the bolt and its locking element have been labeled with numbers over 300.

Auf der Querachse 20 ist außer der Feder 70 als Rastorgan für den Riegel 360 eine zusätzliche Schenkelfeder 306 angeordnet, die in noch näher zu beschreibender Weise mit dem Riegel 360 in Wirkverbindung steht.On the transverse axis 20, in addition to the spring 70, an additional leg spring 306 is arranged as a locking element for the bolt 360, which is operatively connected to the bolt 360 in a manner to be described in more detail.

In dem die Rastnase 361 tragenden Hebelarm des Riegels 360 ist eine im Querschnitt rechtekkige Nut 364 ausgenommen. Am Boden der Nut 364 ist nahe von deren von der Achse 50 entferntem Ende ein Rastvorsprung 365 ausgebildet. Zwischen dem Rastvorsprung 365 und dem der Achse 50 benachbarten Ende der Nut 364 verläuft diese nach einem Bogen.In the lever arm of the latch 360 carrying the latching lug 361, a groove 364 with a rectangular cross section is excluded. A locking projection 365 is formed on the bottom of the groove 364 near its end remote from the axis 50. Between the locking projection 365 and the end of the groove 364 adjacent to the axis 50, the groove runs in an arc.

Die oben erwähnte zusätzliche Schenkelfeder 306, deren einer Schenkel 306a im Schwenkteil 30 verankert ist, greift mit ihrem anderen Schenkel 306b in die Nut. 364 ein. Das Ende 306c dieses Schenkels 306b ist, wie die Fig. 17 bis 20 zeigen, kreisbogenförmig ausgebildet. Es kann aber auch eine Rolle tragen. Legt man im Berührungspunkt des Endes 306c des Schenkels 306b mit dem Grund der Nut 364 eine Normalebene auf die Schenkelachse, so schließt diese mit einer Tangentialebene an den Nutengrund einen Winkel y ein, der größer als der Reibungswinkel zwischen den Materialien des Riegels 360 und der Schenkelfeder 306 ist.The above-mentioned additional leg spring 306, one leg 306a of which is anchored in the pivoting part 30, engages in the groove with its other leg 306b. 364 a. The end 306c of this leg 306b, as shown in FIGS. 17 to 20, is designed in the form of a circular arc. But it can also play a role. If, at the point of contact of the end 306c of the leg 306b with the base of the groove 364, a normal plane is placed on the leg axis, this includes an angle y with a tangential plane at the base of the groove, which angle is greater than the friction angle between the materials of the bolt 360 and the leg spring 306 is.

Zum besseren Verständnis der durch die Weiterentwicklung des Riegels 360 erzielbaren Effekte wird vorerst die Funktion der Skibindung nach den früheren Ausführungsformen kurz wiederholt und dann die Funktion der weiterentwickelten Ausführungsform erörtert. Dabei entspricht Fig. 17 der Fahrtstellung der Skibindung, wie sie in Fig. 14 wiedergegeben ist, und Fig. 18 der Skibindung mit gelöstem Riegel. In den Fig. 19 und 20 sind Zwischenstellungen des Riegels und des einen Schenkels der Schenkelfeder während des Aussteigvorganges gezeigt.For a better understanding of the effects that can be achieved through the further development of the bar 360, the function of the ski binding according to the earlier embodiments is briefly repeated first and then the function of the further developed embodiment is discussed. 17 corresponds to the driving position of the ski binding, as shown in FIG. 14, and FIG. 18 corresponds to the ski binding with the bolt released. 19 and 20 intermediate positions of the bolt and one leg of the leg spring are shown during the alighting process.

Die Funktion der Skibindung nach den früheren Ausführungsformen ist wie folgt: Beim Einsteigen in die geöffnete Bindung wird der hier nicht dargestellte Skischuh schräg in die Halteschale 40 von oben eingeschoben.The function of the ski binding according to the previous embodiments is as follows: When getting into the opened binding, the ski boot, not shown here, is inserted obliquely into the holding shell 40 from above.

Daraufhin wird der Skischuh gemeinsam mit der Halteschale 40 nach unten über die Stellung nach Fig. 16 in die Stellung gemäß Fig. 14 verschwenkt und durch die Verriegelungszapfen 32 festgehalten, welche die durchgehenden Öffnungen der Sohlenverlängerung durchdringen. Der Riegel 360, welcher um die Achse 50 verschwenkbar ist, gleitet dabei mit seiner Rastnase 361 über den Quersteg 43 der Halteschale 40 (s.Fig. 16) und wird schließlich in der Rastnut 43a des Quersteges 43 verrastet (vg.Fig. 14). Damit ist die Bindung geschlossen, und die Halteschale 40 sowie der Schwenkteil 30, sind gemeinsam gegen die Wirkung eines hier nicht dargestellten elastischen Elementes (vgl. das Element 90 in Fig. 1) um die Querachse 20 schwenkbar.Thereupon the ski boot together with the holding shell 40 is pivoted downward over the position according to FIG. 16 into the position according to FIG. 14 and held by the locking pins 32 which penetrate the through openings of the sole extension. The latch 360, which can be pivoted about the axis 50, slides with its locking lug 361 over the crosspiece 43 of the holding shell 40 (see FIG. 16) and is finally locked in the locking groove 43a of the crosspiece 43 (see FIG. 14). . The binding is thus closed, and the holding shell 40 and the swivel part 30 can be pivoted together about the transverse axis 20 against the action of an elastic element (not shown here) (see element 90 in FIG. 1).

Will jedoch der Skiläufer mit seinem Skischuh aus der Bindung aussteigen, so drückt er die Spitze seines Skistockes in die Vertiefung 362 des Riegels 360, wodurch dieser entgegen der Kraft der Riegelfeder 80 in den Fig. 14 und 17 entgegen dem Uhrzeigersinn verschwenkt wird. Gleichzeitig wird die Rastnase 361 aus der Rastnut 43a des Quersteges 43 der Halteschale 40 herausgehoben, so daß sich letztere gegenüber dem Schwenkteil 30 solange verschwenken kann, bis die Verriegelungszapfen 32 die Aussparungen in der Sohlenverlängerung des Skischuhs verlassen haben. Dabei muß der Skiläufer während des gesamten Aussteigvorganges mit seinem Skistock den Riegel 360 in der Öffnungsstellung niedergedrückt halten.However, if the skier wants to get out of the binding with his ski boot, he presses the tip of his ski pole into the recess 362 of the latch 360, whereby this is pivoted counterclockwise against the force of the latch spring 80 in FIGS. 14 and 17. At the same time, the locking lug 361 is lifted out of the locking groove 43a of the crossbar 43 of the holding shell 40, so that the latter can pivot relative to the pivoting part 30 until the locking pins 32 have left the cutouts in the sole extension of the ski boot. The skier must hold down the latch 360 in the open position with his ski stick during the entire alighting process.

Um nun diesen Aussteigvorgang zu erleichtern, wird der Riegel 360 in der verschwenkten Lage nach der erfindungsgemäßen Weiterentwicklung durch den Schenkel 306b der Schenkelfeder 306 festgehalten (s.Fig. 15 und 18). Dadurch muß der Skiläufer während des Aussteigvorganges den Riegel 360 nicht in niedergedrücktem Zustand halten, sondern kann sich beim Aussteigen aus der Bindung mit seinen beiden Skistöcken in der Loipe abstützen.In order to facilitate this exit process, the bolt 360 is held in the pivoted position after the further development according to the invention by the leg 306b of the leg spring 306 (see FIGS. 15 and 18). As a result, the skier does not have to hold the latch 360 in the depressed state during the exiting process, but can be supported with his two ski poles in the cross-country trail when exiting the binding.

Während dieses Aussteigens wird durch Hochschwenken der Halteschale 40 der Schenkel 306b der Schenkelfeder 306 mit einem kurzen Leerweg durch den Quersteg 43 der Halteschale 40 über den Rastvorsprung 365 des Riegels 360 gedrückt, wobei dessen Rastnase 361 bereits über den oberen Endbereich des Quersteges 43 der Halteschale 40 gelangt ist (s.Fig. 19). Hiedurch wird erreicht, daß die Schenkelfeder 306 bei weiterem Hochschwenken der Halteschale 40 mittels des Quersteges 43, sowie unterstützt durch die Riegelfeder 80, in ihre Bereitschaftsstellung zurückverschwenkt (gedrückt) wird.During this disembarkation, by pivoting up the holding shell 40, the leg 306b of the leg spring 306 is pressed with a short free travel through the transverse web 43 of the holding shell 40 over the latching projection 365 of the bolt 360, the latching lug 361 of which is already over the upper end region of the transverse web 43 of the retaining shell 40 has arrived (see Fig. 19). This ensures that the leg spring 306 is pivoted back (pressed) into its ready position when the holding shell 40 is pivoted further upwards by means of the crossbar 43 and supported by the locking spring 80.

Somit wird die Schenkelfeder 306 bei einem willkürlichen Aussteigen zwangsläufig in ihre Ausgangsstellung zurückgeführt. Der oben erwähnte Leerweg ist so bemessen, daß die Oberseite des Quersteges 43 der Halteschale 40 von der Rastnase 361 des Riegels 360 während des Aussteigvorganges übergriffen wird, so daß ein Wiedereinrasten oder ein Sperren verhindert wird (s.Fig. 19 und 20). Damit ist die Bindung für einen neuerlichen Einsteigvorgang vorbereitet.Thus, the leg spring 306 is inevitably returned to its starting position in the event of an arbitrary exit. The free travel mentioned above is such that the upper side of the crosspiece 43 of the holding shell 40 is overlapped by the latch 361 of the latch 360 during the alighting process, so that a re-engagement or a locking is prevented (see FIGS. 19 and 20). The binding is thus prepared for a new boarding process.

Die in Fig. 21 dargestellte Schenkelfeder, die der Schenkelfeder 306 des vorangehenden Ausführungsbeispieles nach den Fig. 13 bis 20 entspricht, ist in ihrer Gesamtheit mit 316 bezeichnet. Diese Schenkelfeder 316 ist - von der Seite gesehen - etwa U-förmig ausgebildet. Sie besitzt zwei Schenkel 316a, die im Schwenkteil 30 der Bindung verankert werden. Die beiden anderen Schenkel 316b sind durch einen Quersteg 316c miteinander verbunden. Dieser Quersteg 316c wird in der entsprechend breiten Nut des Riegels 360 geführt. Die Windungen 316d der Schenkelfeder 316, die sich zwischen den Schenkeln 316a und 316b befinden, sind auf der im Lagerbock 10 gelagerten Querachse 20 der Skibindung angeordnet.The leg spring shown in FIG. 21, which corresponds to the leg spring 306 of the previous exemplary embodiment according to FIGS. 13 to 20, is designated in its entirety by 316. This leg spring 316 is - seen from the side - approximately U-shaped. It has two legs 316a which are anchored in the swivel part 30 of the binding. The other two legs 316b are connected to one another by a crossbar 316c. This crossbar 316c is guided in the correspondingly wide groove of the bolt 360. The turns 316d of the leg spring 316, which are located between the legs 316a and 316b, are arranged on the transverse axis 20 of the ski binding mounted in the bearing block 10.

Die Erfindung ist auf die dargestellten Ausführungsbeispiele nicht eingeschränkt. Die Ausgestaltung des Quersteges von der Halteschale mit einem erhabenen Bereich zur zusätzlichen Sicherung des Riegels kann auch bei der zweiten Ausführungsform nach den Fig. 8 bis 9 erfolgen. Ebenso kann auch die Verstärkung der Schließkraft der Halteschale bei der zweiten Ausführungsform verwirklicht werden.The invention is not restricted to the exemplary embodiments shown. The Ausge Design of the crossbar from the holding shell with a raised area for additional securing of the bolt can also be done in the second embodiment according to FIGS. 8 to 9. Likewise, the strengthening of the closing force of the holding shell can also be realized in the second embodiment.

Soll die Schließkraft der Halteschale weiter erhöht werden, so muß die Lage des Riegels im offenen Zustand der Bindung stärker in seiner Schließrichtung verdreht sein als im geschlossenen Zustand, damit der Federweg, der beim Schließen der Bindung zurückgelegt wird, ein größerer ist. Dies könnte z.B. durch einen im Riegel tiefer eingefrästen hohlkehlenförmigen Anschlag erreicht werden. Durch verschiedenartige Ausgestaltung von Riegel und Quersteg kann die Lage des Riegels bei offener und geschlossener Bindung variiert werden und dadurch die Größe des Schwenkwinkels des Riegels beim Schließen der Bindung verändert werden.If the closing force of the holding shell is to be increased further, the position of the bolt in the open state of the binding must be rotated more in its closing direction than in the closed state, so that the spring travel which is covered when the binding is closed is greater. This could e.g. can be achieved by a groove shaped like a hollow in the bolt. By means of different configurations of the bolt and crossbar, the position of the bolt can be varied with the binding open and closed, and the size of the pivoting angle of the bolt can be changed when the binding is closed.

Des weiteren kann das in der Nut des Riegels geführte Ende des zugehörigen Schenkels der Schenkelfeder auch mit einem abgerundeten, z.B. kugelförmigen, Kopf versehen sein.Furthermore, the end of the associated leg of the leg spring guided in the groove of the bolt can also be provided with a rounded, e.g. spherical, head provided.
