Definitions

  • the invention relates to a ski binding, in particular a touring ski binding, for mounting on a top of a ski, comprising a front automatic machine for holding a ski boot in a toe area of the ski boot and a heel counter for holding the ski boot in a heel area of the ski boot.
  • the automatic heel comprises a heel holding means for holding the ski boot in the heel area of the ski boot.
  • the heel counter has a downhill configuration in which the heel-holding means may cooperate with the ski boot such that the heel region of the ski boot is locked in a lowered position towards the ski.
  • the heel unit in the downshift configuration allows a safety release in the forward direction and a side safety release to release the ski boot from the heel unit when the ski boot is held in the heel counter.
  • the front automatic comprises two toe holding means for holding the ski boot in the toe area of the ski boot. Furthermore, the front-end automatic machine has a first holding configuration in which the two toe-holding means are in a holding position and can interact with the ski boot in the holding position such that the ski boot is held pivotably on the front automatic machine about an axis oriented horizontally in the ski direction. In addition, the front automatic machine has a prestressable elastic element, by means of the prestressing of which the two toe holding means in the first holding configuration of the front automatic machine are pretensioned with their holding force towards their holding position.
  • ski bindings are subdivided into piste bindings, which are used only for downhill skiing and downhill skiing, and touring bindings, which are also used for walking on skis, in particular for ascending with the help of climbing skins attached to the skis. While the former only have to ensure a reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must be brought to ascend additionally from the downhill to a climbing position in which the ski boot is pivotable about an axis in Skiquerides pivotally in the heel area of the ski to allow for joint movement between the ski boot and the ski to go.
  • Touring ski bindings can be divided into two types.
  • One type comprises a ski boot carrier which can be pivoted relative to the ski and to which the ski boot is held by binding jaws.
  • a representative member of this type of touring ski bindings is, for example, in EP 0 754 079 B1 (Fritschi AG ).
  • the second type of touring ski bindings does not include such a ski boot carrier.
  • the ski boot is pivotally mounted in a toe area on the sole in a ski-mounted front automat.
  • the automatic heel unit is also fixedly mounted in a distance from the front automaton on the ski adapted to a ski boot sole length and locks the shoe in the heel area in the downhill position.
  • ski boots In the ascent position, the heel of the heel is released from the heel counter, so that the heel of the heel can be lifted off the ski and swiveled around the bearing on the front automat.
  • suitable ski boots this typically have in the toe area two lateral recesses for pivotal mounting in the front vending machine.
  • recesses which are open at the rear are formed on the shoe sole into which holding means of the heel unit can engage.
  • ski boots on a stiff or only slightly bendable sole. In the latter case, the ski boots can be formed bendable, for example, in the ball area of the foot.
  • ski longitudinal direction means along the orientation of the longitudinal axis of the ski.
  • skiparallel means aligned for an elongate object along the longitudinal axis of the ski.
  • ski-parallel means aligned parallel to the sliding surface of the ski.
  • ski direction means a direction transverse to the ski longitudinal direction, which, however, need not be oriented exactly at right angles to the longitudinal axis of the ski. Their orientation may also be slightly different from a right angle.
  • ski center means a center of the ski in the ski direction
  • ski manifest does not mean that it can move in relation to the ski.
  • ski refers to the reference system of (fictitious) skis.
  • front, “rear”, “top”, “bottom” and “side” refer to “front”, “rear”, “top”, “bottom” and “side” of the ski.
  • horizontal and vertical refer to the ski, with “horizontal” lying in a ski-parallel plane and “vertical” oriented perpendicular to this plane.
  • a touring ski binding of the above introduced second type is in the EP 0 199 098 A2 (Barthel ) and sold under the trademark Dynafit.
  • the binding front part of this system comprises two toggle levers, which are arranged opposite each other in the cross-machine direction and each are pivotally mounted about an axis extending in the longitudinal direction of the ski.
  • the two toggle each have an upwardly directed and a sideways aligned arm, which are arranged at right angles to each other.
  • the upwardly oriented arms each comprise a center of the truncated cone or a hemispherical pin, which can engage in recesses provided in the toe area of a ski boot.
  • the sideways aligned arms of the toggle point as the pins towards the ski center, but are connected via a spring device with each other in operative connection. Since the two toggle levers are spring-loaded with each other via the laterally oriented arms by the spring device, they can by overcoming a dead center position in which the two sideways arms are aligned in a linear extension to each other, downwards and upwards snap. When the sideward arms are snapped down, the upwardly directed arms are pivoted together. On the other hand, when the sideways-aligned arms are snapped upwards, the upwardly directed arms are swung apart. Accordingly, the pins for holding a ski boot are closer to each other in the first case and further apart in the second case.
  • this position of the binding front part is a holding configuration.
  • the pins are biased toward their holding position with a holding force.
  • the holding means are sufficiently far apart so that the ski boot is released.
  • This position also serves to enter the binding front with the ski boot. Accordingly, this position of the binding front part is an entry-level configuration.
  • this includes in the EP 0 199 098 A2 (Barthel ) described binding front part of an opening lever which is pivotable about an axis oriented in the ski direction and which surrounds the connection of the two laterally aligned arms of the toggle lever top and bottom.
  • the laterally oriented arms of the toggle lever can be pushed upwards, where they snap in the entry position.
  • the laterally aligned arms of the toggle By reverse operation of the opening lever, the laterally aligned arms of the toggle but can also be pressed down, where they snap in the holding position.
  • the ski boot can be detached from the ski binding system even without actuating the opening lever.
  • the ski boot is first released from the heel counter and then from the binding front part. If it is a frontal fall, the ski boot is released by a safety release from the heel counter up and tilted forward in the binding front. If the forward or upward force on the ski boot is sufficiently large, then the ski boot can also be torn out of the binding front part by overcoming the force acting on the two angle levers. If the ski boot is kept in the binding front is pivoted sufficiently far forward, so he pushes with his toe on the opening lever, so that the toggle lever and thus the pins from the holding position are slightly pivoted apart until the ski boot is detached from the binding front part.
  • the ski boot is released by a lateral safety release of the heel unit in the lateral direction and rotated about a lying in the toe area of the ski boot vertical axis.
  • the ski boot is rotationally released from the binding front part by the holding force acting on the toggle lever is overcome.
  • the EP 0 199 098 A2 also describes a toe binding machine for a touring ski binding comprising a ski base and a heel holder.
  • a bracket made of resilient material, so that the two free ends of the bracket protrude in the longitudinal direction of the ski. These free ends may engage corresponding recesses in a heel area of a ski boot to hold the ski boot.
  • the heel holder is mounted rotatably on the base about a vertical axis of rotation perpendicular to the ski surface. About a bias by a spring, the heel holder is biased to a central position in which point the two free ends of the bracket in the ski longitudinal direction to the front.
  • the term "safety release” means the controlled release of a ski boot held in the ski binding when the magnitude of a force applied externally to the ski boot, ski binding or ski exceeds a predetermined limit. If the term is used in relation to an element of the ski binding, such as, for example, the automatic heel unit or the front automatic machine, then the release refers to a release of the ski boot previously held in this element of the ski binding from this element.
  • the automatic heel unit can enable a safety release, whereby the ski boot can be released from the heel counter. If nothing else is mentioned, it is irrelevant whether the ski boot is still held by the automatic front end machine after such a safety release by the automatic heel unit or not.
  • a force is usually provided with a prestressed elastic element which must be overcome for releasing the ski boot from the respective element of the ski binding or from the ski binding. Often this can be set by adjusting the bias of the elastic element of the limit, which must be exceeded by the force acting on the outside of the ski boot, the ski binding or the ski force for a safety trip. Therefore, the phrase "setting the safety release” below means the setting of the limit, which must be exceeded at a corresponding safety release of the external force for release of the ski boot.
  • the automatic heel unit When in the EP 0 199 098 A2 (Barthel ), the automatic heel unit allows a safety release in the forward direction and a lateral safety release.
  • a safety release in the forward direction the two free ends of the bracket are elastically bent apart until the heel portion of the ski boot is released from the free ends of the bracket and can be removed upwards from the heel unit.
  • the limit of the necessary force on the ski boot upwards or on the ski binding or the ski downwards is determined by the elastic bendability of the strap. This limit depends on the geometry, mounting and material of the bracket. He can thus be adjusted only by the choice of the bracket.
  • the heel area of the ski boot is released laterally from the heel unit if a lateral force on the ski boot, the ski binding or the ski exceeds a limit value.
  • the heel holder is pivoted by the lateral force from the heel of the ski boot on the bracket from its central position away against the bias of the spring about its axis of rotation to the side until the strap releases the heel area of the ski boot.
  • This lateral safety release limit is determined by the bias of the spring biasing the heel holder toward its central position.
  • the limit value can be set by adjusting the preload of the spring by means of an adjusting screw.
  • the binding front part allows for in the EP 0 199 098 A2 (Barthel ) described ski binding no safety release in the sense of the present text.
  • the two pins are biased by a holding force in their holding position. Also, this holding force is overcome to release the ski boot from the binding front part.
  • the ski binding or the ski is necessary to release the ski boot from the binding front part. This is essentially due to the pins being moved away from each other to move them away from their holding position.
  • the ski boot can be released from the binding front part, in particular by twisting in relation to the binding front part in the case of pins spaced apart from one another. Accordingly, the binding front part neither allows a controlled release of the ski boot nor exists a predetermined limit which is to be overcome by the force acting on the ski boot, the ski binding or the ski for releasing the ski boot from the binding front part.
  • the in the EP 0 199 098 A2 (Barthel ) described ski binding has the disadvantage that the safety release can be set only limited.
  • the reason for this is on the one hand that the limit value for a safety release in the forward direction can only be set by exchanging the bracket.
  • the reason is that in the lateral safety release of the heel holder is pivoted about the vertical axis of rotation and that thereby the free ends of the bracket are pivoted away from the ski boot to the rear.
  • the heel of the ski boot is well guided by the heel holder only a short distance in Skiquerides at a lateral safety release, because the free ends of the strap slip out of the recesses in the ski shoe heel. Accordingly, a precise adjustment of the lateral safety release to be exceeded by the force limit threshold is difficult.
  • the EP 2 384 764 B1 discloses an automatic heel unit which also provides a safety release in the forward direction and a lateral safety release.
  • the heel counter includes a base and a heel holder that around a perpendicular to the ski surface aligned, vertical axis of rotation, is rotatably mounted on the base.
  • the heel holder comprises two pins, which are biased by a spring on each other to a holding position and hold the heel area of the ski boot. About the same spring and the heel holder is biased to a central position, in which the pins point in the ski longitudinal direction to the front. The spring thus assumes a double function.
  • a safety release in the forward direction when a force from the heel area of the ski boot on the heel unit in the upward direction of the ski exceeds a first limit, the pins are moved against their bias to the outside of the ski center away, so that the heel area of the in the Ski binding held ski boot is released to the top.
  • a lateral safety release when a force exerted by the heel area of the ski boot in the lateral direction on the heel unit exceeds a second limit, the heel holder is pivoted against its bias about the vertical axis of rotation. The heel area of the ski boot is thereby released from the pins and can move away from the ski in a lateral direction.
  • This automatic heel also has the disadvantage that the safety release in the forward direction as well as the lateral safety release is limited adjustable.
  • the fact that the spring in the heel holder is used both for biasing in the heel holder rotational position and for biasing the pins to their holding position also limits the forward and side safety release limits. This additionally limits the adjustability of the two safety releases.
  • the object of the invention is to provide a ski binding associated with the aforementioned technical field, which increases the safety for the skier.
  • the bias of the elastic element of the front automatic is adjustable and thus the holding force is adjustable. It means “adjustable” preferably that the holding force can be changed by hand without tools or by hand with tools and adjusted so that without one or more elements of the ski binding removed, additionally mounted or replaced.
  • the advantage of the invention is that with the adjustment of the holding force in the front vending machine and the limit, which must be exceeded by a force on the ski boot, the ski binding or the ski for a lateral safety release by the heel counter can be adjusted.
  • the reason for this is that in case of a lateral safety release by the heel counter, the heel of the ski boot is moved in the ski direction until the ski boot is released from the heel counter.
  • the ski boot is held in the front automatic by the two pins engage in the recesses provided in the toe area of the ski boot. Therefore, the ski boot is rotated about a vertically oriented axis during the lateral safety release.
  • the depressions in the ski boot are pivoted about the vertically oriented axis relative to the pins until the ski boot is also detached from the front automatic machine. Since the pins are moved against the holding force, in addition to the lateral safety release and the holding force to overcome.
  • the limit to be overcome for a lateral safety release by the heel counter can be adjusted by adjusting the holding power of the front automat.
  • the safety release of the entire ski binding can be better adjusted, which means that a controlled release of the ski boot held in the ski binding is made possible with a safety release.
  • the mode of release of the ski binding during a safety release can be better adapted to the skier. This increases the safety for the skier.
  • Another advantage of the invention is that can be adjusted independently of the heel unit by adjusting the holding force, how much a ski boot can be kept in the front vending machine. Therefore, by appropriate adjustment of the holding force, the safety for the skier can be additionally increased.
  • the automatic heel unit on a prestressable elastic security element by the bias of a force can be generated, which is to be overcome in the automatic heel held ski boot both in the safety release in the forward direction and in the lateral safety release to release the ski boot heel.
  • the bias is easily adjustable by the choice of the elastic security element.
  • a limit of the force is adjustable, which is to be overcome in the automatic heel held ski boot both in the safety release in the forward direction and in the lateral safety release. This allows the characteristic of the safety release in the forward direction and the lateral safety release to be tailored to the skier.
  • the ratio of the limit value of the safety release in the forward direction to the limit of the lateral safety release of the heel unit can also by adjusting the bias of the elastic element of the front automatic be set. This allows the safety release in the forward direction and the lateral safety release to be better adjusted to the respective requirements in order to minimize the likelihood of false triggering. This further increases safety for the skier.

Thereafter, the ski boot swings forward with its heel area around an axis oriented horizontally in the ski direction. From a certain pivot position of the ski boot, a front end of the toe area of the ski boot contacts a rearwardly facing side of the ski boot release actuator 9. As the ski boot continues to pivot forward, the front end of the toe area of the ski boot presses on the ski boot release actuation element 9.
  • the opening lever shaft 16 is pivotally mounted on the base member 2, pivots the upper free end of Skischuhkiebetuschistselement 9 by the force of the ski boot forward and thereby pushes the short arm of the blocking element 8 forward down and thus the opening lever 7 with its front free end down.
  • the opening lever 7 is pressed with its front free end to the opening lever axis 16 forward and down from its holding position. Accordingly, the rear portion of the opening lever 7 moves about the pivot axis 16 upwards and the toggle levers 3.1, 3.2 are at least temporarily moved outward from the center of the ski.
  • the toe-holding means 4.1, 4.2 are also at least temporarily moved away from their holding position and away from each other. As a result, the toe area of the ski boot is released from the front automatic machine 1.
  • FIGS. 5a and 5b show the front vending machine 1 in the second holding configuration.
  • FIG. 5a shows a side view of a vertically aligned in the ski longitudinal section through the front vending machine 1.
  • the section runs vertically in the direction of the center of the ski through the toggle levers 3.1, 3.2.
  • the heel area of the ski boot is released by the heel holding means of the heel unit and the front automatic machine 1 is in the second holding configuration, so that the toe holding means 4.1, 4.2 can cooperate with the toe area of the ski boot such that the ski boot can move around a horizontally in Skiquerraum aligned axis is pivotally held on the front vending machine 1. This allows walking on skis.
  • FIG. 5a As in FIG. 5a can be seen, located in the second holding configuration of the front vending machine 1, the opening lever 7 in its holding position.
  • FIG. 5b It can also be seen that the toe-holding means 4.1, 4.2 are also in their holding position in the second holding configuration.
  • FIG. 5a It can be seen that, in contrast to the first holding configuration of the front automatic machine 1 but the free end of the long arm of the blocking element 8 is pivoted about the opening lever axis 16 and pivot axis upwards, so that the long arm of the blocking element 8 has substantially vertically upwards. The short arm of the blocking element 8 points in this position of the blocking element 8 to the rear.
  • FIG. 5a It can be seen that, in contrast to the first holding configuration of the front automatic machine 1 but the free end of the long arm of the blocking element 8 is pivoted about the opening lever axis 16 and pivot axis upwards, so that the long arm of the blocking element 8 has substantially vertically upwards. The short arm of the blocking element 8 points in this position of the
  • the blocking element 8 is engaged with a located between the long and the short arm groove 28 via the cam 27 of the housing 11. As a result, the blocking element 8 is in a stable position in this position. Since the blocking element 8 is mounted in the front region of the opening lever 7, the blocking element 8 supports the front region of the opening lever 7 downwards. As a result, the front free end of the opening lever 7 is not pivotable about the pivot axis 16 forwards and downwards.
  • the Skischuhkegabebet2011istselement 9 is in the deactivated position, since the SkischuhkegabebetHence,selement 9 in this position of the blocking element 8, the opening lever 7 can not adjust.
  • ski boot release operation member 9 is through Actuation of the blocking element 8 from its activated to its deactivated position and back adjustable.
  • the upper end of the ski boot release actuating element 9 is pivoted by the short arm of the blocking element 8 about the pivot axis 16 to the rear.
  • the ski boot release actuator 9 is thereby adjusted from its activated to its deactivated position.
  • the free end of the long arm of the blocking element 8 is pivoted about the axis 17 from bottom to top.
  • the upper end of the ski boot release actuating element 9 is pivoted rearwardly about the opening lever axis 16 or pivot axis until the ski boot release actuating element 9 is in its deactivated position.
  • the invention is not limited to ski bindings with the above-described front automatic machine 1 and the two mentioned heel machines. Both the front and the heel machine can be designed differently. For example, it is not necessary for the front automatic to have two toggles, a ski boot release actuator or an opening lever as described above.
  • the front automatic does not necessarily have a first and a second holding configuration.
  • the front-end machine can also have only one holding configuration or, in addition to the first and second holding configuration, also one or more further configurations which differ from the described holding configurations and the entry-level configuration.
  • the described elements of the front automate can also be designed differently.
  • the opening lever need not include a blocking element. If a blocking element is present, this can also be arranged separately from the opening lever as a separate element.
  • the ski boot release actuator may also only have an activated position or in addition to the activated and deactivated position have further positions. If, in addition to the first and the second holding configuration, the front-end machine also has further configurations, the ski boot release actuating element can also have one or more positions in these other configurations, which are different from the holding configurations.
  • a different elastic element than the spring 20 can be used in the front vending machine.
  • the power transmission from the elastic member may be configured differently to the toe holding means as a piston, an opening lever and toggle.
  • the front automat can have other holding means than the described toe holding means.
  • a front automatic according to the invention can also be used for other ski bindings such as, for example, downhill bindings.
  • a front automatic is provided, which increases the safety for the skier.
