Abstract

The binding has a double joint mechanism with a frame (1) connectable to the shoe and connected to an intermediate part (2) through an articulated joint (A) which is placed under the ball of the foot between the frame and intermediate part. The joint (B) which is fixed on the ski is placed underneath the area of the little toe. The intermediate part has a stop (4) opposite the binding frame so that both in the downward and upward direction the binding frame is prevented from swivelling up towards the shoe tip whilst the shoe tip can still swivel down.

Description

Die Erfindung betritt eine Tourenschibindung mit Doppelgelenksmechanik, wobei ein mit dem Schuh verbindbares rahmenartiges Gestell über ein Gelenk mit einem Zwischenteil verbunden ist, welcher seinerseits über ein schifestes Gelenk mit dem Schi verbunden ist.The invention enters a touring ski binding with double-joint mechanism, one with frame-like frame connectable to the shoe via a joint with an intermediate part is connected, which in turn is connected to the ski via a fixed joint.

Bekannte Lösungen sind in ihrer Ausführung mehr (WO 87/01296) oder weniger (AT 404.799) kompliziert, haben aber alle den Nachteil, daß die zwei Gelenkpunkte sehr weit auseinander liegen. Daraus resultiert ein inhomogener Bewegungsablauf, bei dem der Übergang von der ersten Bewegungsphase (Drehpunkt am Ballen) in die zweite Bewegungsphase (Drehpunkt an der Schuhspitze) als störend empfunden wird und letztlich einen Mehraufwand an Kraft für das Gehen erfordert.Known solutions are more (WO 87/01296) or less (AT 404.799) complicated, but all have the disadvantage that the two pivot points are very wide apart. This results in an inhomogeneous movement, in which the Transition from the first movement phase (pivot point on the bale) to the second Movement phase (pivot point at the toe) is perceived as bothersome and ultimately requires more effort for walking.

Die vorliegende Erfindung setzt sich zum Ziel, in einer einfachen Konstruktion eine Kinematik zu realisieren, die der Ergonomie des natürlichen Gehens besser entspricht und gleichzeitig als homogen und weich empfunden wird.The present invention aims to provide a simple construction Realize kinematics that better match the ergonomics of natural walking and is felt as homogeneous and soft at the same time.

Dies wird erfindungsgemäß dadurch erreicht, daß das Gelenk (A) zwischen rahmenartigem Gestell (1) und Zwischenteil (2) unterhalb des Fußballens und das schifeste Gelenk (B) unterhalb des Bereiches des letzten Zehengliedes gelegen ist.This is achieved in that the joint (A) between frame-like Frame (1) and intermediate part (2) below the ball of the foot and the shifter-fixed joint (B) is located below the area of the last phalange.

In weiterer Ausbildung der Erfindung ist vorgesehen, daß das Zwischenteil (2) gegenüber dem Bindungsgestell (1) einen Anschlag (4) aufweist, sodaß sowohl in Abfahrts- wie auch in Aufstiegsstellung ein Verschwenken des Bindungsgestells (1) in Richtung Schuhspitze nach oben verhindert wird, ein Verschwenken in Richtung Schuhspitze nach unten jedoch möglich ist.In a further embodiment of the invention it is provided that the intermediate part (2) opposite the binding frame (1) has a stop (4), so that both in downhill and in Ascent position swiveling the binding frame (1) towards the toe is prevented at the top, but can be swiveled downwards towards the toe is.

Als weitere Ausgestaltung ist erfindungsgemäß vorgesehen, daß die Rotation des Bindungsgestells (1) um das Zwischenteil (2) und die Rotation des Zwischenteiles (2) um den schifesten Lagerbock (3) derart mit Federn beaufschlagt sind, daß die Bindung im unbelasteten Zustand unter Vorspannung eine Ruhelage einnimmt, in der das Zwischenteil (2) an der Schioberfläche aufliegt und sich das Bindungsgestell (1) in zur Schioberfläche paralleler Stellung befindet.As a further embodiment, the invention provides that the rotation of the Binding frame (1) around the intermediate part (2) and the rotation of the intermediate part (2) around the schifesten bearing block (3) are so loaded with springs that the binding in unloaded state under pretension assumes a rest position in which the intermediate part (2) rests on the ski surface and the binding frame (1) is in contact with the ski surface parallel position.

In den Zeichnungen wird ein Ausführungsbeispiel der Erfindung näher erläutert. Die Figuren 1 bis 3 zeigen die Bindung in verschiedenen Phasen der Gehbewegung. Der Schuh ist auf einem rahmenartigen Gestell (1) fixiert. Dieses Bindungsgestell (1) ist über ein unterhalb des Fußballens, d. h. 5-11 cm hinter der Schuhspitze gelegenes Gelenk (A) mit einem Zwischenteil (2) verbunden. Das Zwischenteil (2) seinerseits ist über ein - von der Schispitze aus gesehen - vor dem ersten Gelenk liegendes zweites Gelenk (B) mit einem schifesten Lagerbock (3) verbunden. Das Gelenk (B) befindet sich dabei im Bereich unterhalb des letzten Zehengliedes, d. h. je nach Schuhgröße 2-5 cm, hinter der Schuhspitze.

  • Fig. 1. zeigt diese Ausführungsform der Bindung in zur Schioberfläche paralleler Stellung.
  • Fig. 2 zeigt die Bindung nach einer ersten Phase des Schrittes. Das unterhalb des Ballens gelegene Gelenk (A) ermöglicht in der ersten Phase des Schrittes eine Bewegung, die der Flexion im Fußballen beim Gehen mit einer flexiblen Sohle ähnlich ist.
    • In the drawings, an embodiment of the invention is explained in more detail. Figures 1 to 3 show the binding in different phases of the walking movement. The shoe is fixed on a frame-like frame (1). This binding frame (1) is connected to an intermediate part (2) via a joint (A) located below the ball of the foot, ie 5-11 cm behind the tip of the shoe. The intermediate part (2) is in turn connected to a bearing block (3) fixed to the ski via a second joint (B) lying in front of the first joint as seen from the ski tip. The joint (B) is located in the area below the last toe link, ie 2-5 cm depending on the shoe size, behind the toe.
  • 1 shows this embodiment of the binding in a position parallel to the surface of the ski.
  • 2 shows the binding after a first phase of the step. The joint (A) located below the ball enables movement in the first phase of the step that is similar to the flexion in the ball of the foot when walking with a flexible sole.

    • Die erste Bewegungsphase wird bei einer Winkelstellung von rund 15 Grad zur Schioberfläche durch einen Anschlag beendet, und die Bewegung des Schuhs wird durch eine Rotation um das zweite Gelenk (A) weitergeführt. Fig. 3 zeigt die Stellung der Bindung in dieser Phase der Bewegung. Die Lage der Gelenkspunkte ermöglicht dabei auch mit steifen Schischuhen einen angenehmen Bewegungsablauf, der harmonisch und nicht zuletzt kräftesparend ist.The first movement phase is at an angle of around 15 degrees Schio surface ended by a stop, and the movement of the shoe is stopped by a Rotation continued around the second joint (A). Fig. 3 shows the position of the binding in this phase of the movement. The position of the articulation points also enables stiffness Ski boots have a pleasant movement that is harmonious and not least is energy saving.

    Es ist auch vorgesehen, daß durch einen Anschlag des Zwischenteils (2) am Bindungsgestell (1), das Hochkippen der Schuhspitze über die horizontale Stellung hinaus, wie es beispielsweise durch das Zurückverlagern des Körperschwerpunktes verursacht werden könnte, verhindert wird. Fig. 1 zeigt eine Ausführungsform, bei der eine Lasche (4) des Zwischenteils (2) in zum Bindungsgestell paralleler Stellung am Bindungsgestell (1) anschlägt. Das Bindungsgestell kann sich auf diese Weise mit seinem vorderen Teil nur nach unten in Richtung Schioberfläche, nicht aber nach oben bewegen. Durch diesen Anschlag ist auch eine Bewegung im vorderen Gelenk (B) so, daß sich die Schuhspitze nach oben bewegt, unterbunden.It is also provided that a stop of the intermediate part (2) on the binding frame (1), tip the shoe tip over the horizontal position as it caused, for example, by shifting the center of gravity back could be prevented. Fig. 1 shows an embodiment in which a tab (4) of the Intermediate part (2) in position parallel to the binding frame on the binding frame (1) strikes. The binding frame can only move in this way with its front part move down towards the ski surface, but not upwards. By this stop is also a movement in the front joint (B) so that the tip of the shoe moves upwards, prevented.

    Weiters ist es zweckmäßig, daß die Rotationsbewegung des Bindungsgestells (1) gegenüber dem Zwischenteil (2) mit einem Federmoment derart beaufschlagt ist, daß das Bindungsgestell unter Vorspannung gegen den Anschlag (4) seine Ruhelage hat. In ähnlicher Weise ist erfindungsgemäß vorgesehen, daß die Bewegung des Zwischenteils (2) um den schifesten Lagerbock (3) mit einem Federmoment derart beaufschlagt ist, daß das Zwischenteil in zur Schioberfläche geschlossener Stellung unter Vorspannung ihre Ruhelage hat. Durch die beiden Federn wird gewährleistet, daß die Bindung beim Transport eine definierte Stellung einnimmt und daß beim Gehen das Schiende auch bei Belastung des Schis durch Schnee nicht nach unten hängt.Furthermore, it is expedient that the rotational movement of the binding frame (1) is opposite the intermediate part (2) is acted upon with a spring torque such that the Binding frame under pretension against the stop (4) has its rest position. More like that According to the invention it is provided that the movement of the intermediate part (2) around the schifesten bearing block (3) is acted upon by a spring torque such that the Intermediate part in the closed position to the ski surface under pretension Has. The two springs ensure that the binding is a occupies a defined position and that when walking, the ski ends even when the ski is under load not hanging down by snow.
