Definitions

  • the invention relates to a heel automaton for a ski binding, in particular a touring ski binding.
  • the inventive automatic heel comprises a heel holder with a holding device for holding a ski boot in the region of a heel of the ski boot.
  • the holding device comprises two arms, which are arranged in a first plane, wherein on each of the two arms a holding means for holding the ski boot in the region of the heel of the ski boot is arranged.
  • the two arms are movable in the first plane relative to each other, whereby a distance between the two holding means is changeable.
  • the holding device comprises a first stub element, which is movable relative to the two arms and relative to the first plane, and a prestressed first elastic element, by the bias of which a first force can be generated on the first stub element.
  • 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.
  • the first type comprises a ski boot carrier pivotable relative to the ski, on 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 relies on ski boots with a stiff sole.
  • the ski boot is pivotally mounted in his toe area in a skim-mounted front automat.
  • the automatic heel unit is also fixed in a distance from the front automat on the ski adapted to a ski boot sole length and locks the ski boot in the heel area in the downhill position.
  • ski boots In the ascent position, the heel of the ski boot is released from the heel unit, so that the ski boot can be lifted off the ski and swiveled around the storage on the front automat.
  • this type of binding suitable ski boots this typically have in the toe area two lateral recesses for pivotal mounting in the front vending machine. Next, they have in the heel area to the rear open recesses into which holding means of the heel unit can intervene.
  • These holding means may be, for example, two forward facing pins.
  • ski boots are commercially available, which have in their heel area recesses for receiving two forward facing pins as holding means.
  • the distance in which the heel counter must be mounted on the ski from the front automatic machine is determined by the length of the sole of the ski boot to be held in the context of an adjustability of the heel piece.
  • 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.
  • AT 402 020 B (Barthel ) such a heel machine. It comprises a housing which is pivotable on a mounting plate about an invisible vertical axis against the force of a spring mounted in the housing. In the upper part of the housing two arms are arranged. In the rear region of these two arms vertical axes are arranged, about which the two arms are pivotally mounted. As a result, the two arms are pivotable in a horizontal plane. The front ends of the two arms cantilever forward relative to the housing. These front ends of the two arms form forward-pointing pins, which serve as holding means by being in Recesses in the heel of a ski boot can intervene to hold the ski boot.
  • the arms carry wedge-shaped oblique surfaces which are perpendicular to the horizontal pivoting plane of the arms and lead laterally apart towards the pins.
  • a U-shaped bracket, which serves as a stub element is pressed by two springs arranged between the arms from back to front against the inclined surfaces of the arms. As a result, the two arms are pressed towards each other.
  • a stop located between the arms prevents the two arms from being pivoted closer than to a minimum distance apart. Therefore, the two pins are held to each other due to the force generated by the springs on the bracket at a predetermined distance.
  • the heel automat according to AT 402 020 B (Barthel ) enables a safety release in the forward direction.
  • the two pins are forced apart against the force of the springs due to the shape of the heel of the ski boot until the heel of the ski boot has detached upwards from the heel counter.
  • the heel box picks up energy.
  • the total energy absorbed by the heel unit depends on the path traveled by the pins to release and on the spring force which has to be overcome during the travel of the pins. Due to the shape of the heel of the ski boot is the path, which is covered by the pins to the release set.
  • the spring force which must be overcome during the path of the pins, can be adjusted in the heel counter. This allows the heel counter to adjust the energy that can be absorbed by the heel counter until a safety trip in the forward direction occurs.
  • This setting is also referred to as setting the tripping force, setting the tripping value or somewhat imprecise simply as setting the safety release.
  • the WO 2012/024809 A1 discloses an automatic heel unit, which belongs to the technical field mentioned above.
  • This automatic heel also includes two forward facing pins which serve as a means of retention and can engage recesses in the heel of a ski boot to hold the ski boot.
  • the pins in the heel unit according to the AT 402 020 B are the pins in the heel unit according to the WO 2012/024809 A1 (Fritschi AG), however, arranged on vertically oriented arms. These arms are mounted in a vertical, transversely aligned to the longitudinal direction of the ski pivotally mounted on the housing of the heel holder. They have at their lower ends to back paragraphs.
  • a spring is arranged, which presses a piston parallel to the arms down against the shoulders arranged on the arms. Characterized the upper ends of the arms are pressed against the arranged between the arms front wall of the housing of the heel holder. As a result, the two arms are held in a position in which the pins are at a predetermined distance from each other.
  • the heel automat according to WO 2012/024809 A1 also enables a safety release in the forward direction. Again, the safety release is set by adjusting the spring force.
  • Both the AT 402 020 B (Barthel ) as well as the WO 2012/024809 A1 (Fritschi AG) describe the respective heel piece as belonging to a touring ski binding, which belongs to the above-mentioned second type.
  • these heel machines can also be used on touring ski bindings of the above-mentioned first type and in piste bindings.
  • these heel machines have the disadvantage that they allow a setting of the safety release only within a limited adjustment range.
  • the reason for this is on the one hand the limited way, which is covered by the pins, until it comes to a release.
  • the limited space for the spring is one reason. The latter means that no stronger spring can be installed without significantly increasing the volume of the heel counter. Accordingly, the heel machines can not be adjusted so that they can absorb high-energy impacts on the ski, the ski boot and the ski binding in a particularly sporty driving style, without causing an unintentional safety release.
  • the object of the invention is to provide a the aforementioned technical field associated automatic heel, which allows a setting of the safety release for a particularly sporty driving in a compact design of the heel unit.
  • the first push member is movable in a second plane oriented substantially perpendicular to the first plane, and the first force, which is aligned in the second plane, can be pressed against the two arms to hold the two arms in a holding position which are the two holding means at a predetermined distance from each other.
  • "in a second plane aligned substantially at right angles to the first plane” means that the smallest intersecting angle measured between the first plane and the second plane is greater than 45 °.
  • this smallest intersection angle measured between the two planes is greater than 70 °, particularly preferably greater than 85 ° or approximately 90 °.
  • the heel machine is mounted exactly on the ski.
  • the heel holder can be mounted directly on the ski.
  • the heel holder can be mounted indirectly via one or more further elements on a ski.
  • the automatic heel unit can have a base element which can be mounted on the ski and on which the heel holder is fastened or on which the heel holder is movably mounted.
  • the heel holder is precisely shaped.
  • the holding device forms the entire heel holder or whether the holding device forms only a part of the heel holder.
  • the holding device is an integral part of the heel holder or whether the holding device forms a separable from the rest of the heel holder unit.
  • the two arms arranged in the first plane may be two physically separate elongated structures. They can each be in one piece or off be composed of several elements. But there is also the possibility that the two arms are two elongated structures that are physically connected to each other. In this case, the two arms and their connection can be made in one piece and formed, for example, by the two free ends of a bent metal bar to a bracket. The connection can also be made as a separate element, which is attached to the two arms and thereby physically connects the two arms together. Regardless of the type of connection, it does not matter whether the arms are themselves integral or made up of several elements.
  • the shape of the first elastic element is irrelevant to the solution of the problem.
  • the first elastic member may be formed by a coil spring, a leaf spring, or any other spring. But it is also possible that the first elastic member is formed of an elastic material without having the shape of a spring.
  • the first elastic element may be a block of elastic material. Regardless of the shape of the first elastic element, the first elastic element may also have a plurality of individual parts and, for example, comprise a plurality of parallel or serially arranged springs.
  • the first stub element can be pressed against the two arms by the first force generated by the prestressing of the first elastic element and oriented in the second plane. Since the second plane is oriented substantially perpendicular to the first plane while the two arms are arranged in the first plane, the first force exerted by the first pushing element thus acts at an angle to align the two arms with the two arms. Therefore, the first elastic member can be easily disposed outside the first plane, so that the space occupied by the first elastic member is separated from the space occupied by the two movable arms.
  • the solution according to the invention has the advantage that it allows the use of a larger and stronger elastic element, without the automatic heel unit having to be constructed larger.
  • the automatic heel unit allows a safety release in the forward direction. This has the advantage that safety is increased for the skier. Alternatively, there is also the possibility that the automatic heel unit does not allow safety release in the forward direction.
  • the two holding means are each formed by a pin, in particular by a forward facing pin.
  • the holding means may also be designed differently. So they can, for example, each form a half of a jaw, which surrounds the heel of the ski boot as in the case of known Pistenitatien rear top and side.
  • the two arms are movable away from their holding position against the first force generated by the prestressed first elastic element.
  • the two holding means are preferably movable away from one another by the two arms are moved away from its holding position against the first force generated by the prestressed first elastic element.
  • the holding means can be moved apart, for example, in a safety release in the forward direction against the first force to release the ski boot. This has the advantage that the ski boot in a safety release in the forward direction can be released in a simple manner.
  • the two holding means are movable relative to each other by the two arms are moved away from its holding position against the first force generated by the prestressed first elastic element.
  • the ski boot can be released in a safety release in the forward direction in a simple manner.
  • the holding means are arranged in the region of a first end of the arms. This has the advantage that the largest part of the arms can be spatially separated from the holding means, so that a heel machine construction with stable mounting of the two arms is made possible, which allows at the same time with the holding means a trouble holding the ski boot.
  • the holding means are not arranged in the region of the first end of the arms.
  • the holding means may be arranged on the arms in the region of the middle of the arms or in the region of one third or quarter of the arm length from the first end of the arms.
  • the two arms are preferably pivotable with their first ends about a pivoting range, which lies in the region of the second, the first ends of the two arms opposite ends of the two arms ,
  • the two arms can be pivotally mounted in the pivoting area about a common axis or each about separate axes, have elastic regions or be connected to each other by an elastic connection.
  • the pivotability of the two arms with their first ends about the pivoting area in the region of the second ends of the two arms has the advantage that the first ends of the arms opposite the second end of the arms cover the greatest possible distance during a pivotal movement of the arms.
  • the holding means are arranged at the first ends of the two arms, this can be used so that the holding means cover the greatest possible distance during a pivoting movement of the two arms. If the first stub element cooperates with the two arms in the region of the first ends of the two arms, optimum transmission of force between the arms and the first stub element can be achieved due to the maximum distance traveled by the arms during a pivoting movement.
  • the two arms are pivotable with their first ends about a pivoting range of the two arms, which between the first ends and the second ends of the two arms is arranged.
  • the two arms can be pivotally mounted in the pivoting area about a common axis or each about separate axes, have elastic regions or be connected to each other by an elastic connection.
  • the two arms are not pivotally mounted, but displaceable. They can maintain their orientation during a shift or additionally be pivotable about a possibly moving, geometric or physical axis.
  • the first push member and the two arms are shaped and cooperate such that the two arms are always biased to the holding position by the first force with which the first push member is pushable against the two arms Holding means are at a predetermined distance from each other.
  • This has the advantage that the two holding means are always biased by the first force generated by the first elastic element to a holding position, which is why even the smallest movement of the holding means from its holding position takes place against the first force. Therefore, a low energy impact on the ski, ski binding, or ski boot causes only a slight movement of the retaining means against the first force, and thus only a slight movement of the ski boot relative to the ski. Accordingly, the ride comfort for the skier is increased.

  • the spindle 10 comprises at its upper end a head with which it is supported against the upper edge of the second push member 9. As a result, the spindle 10 is raised when the second push member 9 is lifted. In the same way, however, the second pusher element 9 is also pulled down when the spindle 10 is moved downwards. After the second stub element 9, the spindle 10 extends downwardly through an opening in the first stub element 8. A diameter of this opening in the first Stem element 8 is slightly larger than a diameter of the spindle 10, so that the first stub element 8 can be moved along the spindle 10 relative to the spindle 10. This makes it possible for the first and second push elements 8, 9 to be moved apart or toward one another in the second plane. Thus, both the two push elements 8, 9 and the spindle 10 are movable relative to the two arms 6.1, 6.2 and relative to the first plane.

  • the threaded nut 11 which is prevented by the sheet metal piece 12 at a co-rotation, along with the sheet metal piece 12 along the spindle 10 depending on the direction of rotation moves up or down. Since a wound around the spindle 10 coil spring 13 is clamped between the threaded nut 11 and the first Stosselement 8, thus, a bias of the coil spring 13 can be adjusted by a rotation of the spindle 10. In this case, the bias of the coil spring 13 due to the position of the sheet metal piece 12 in a window 14 on the back of the central region of the housing 3 can be read.
  • the first stub element 8 is pressed with a aligned in the second plane first force from below upwards against the two arms 6.1, 6.2.
  • the lower end of the coil spring 13 presses with a force which is equal to the first force, the threaded nut 11 down.
  • the spindle 10 is pressed down with the same force. Due to the head of the spindle 10, which is supported against the upper edge of the second push member 9, therefore, the second push member 9 is pressed with this force down.
