Definitions

  • the invention relates to a toe for a ski binding.
  • This front jaw comprises a base element, a radial bearing with a pivot axis, which is arranged in a substantially vertically oriented, extending in the longitudinal direction of the plane, an elastic element, at least two shock elements, which are arranged around the radial bearing, and a holding element for holding a ski boot in Area of a ski boot top.
  • the holding element is mounted by the radial bearing about the pivot axis pivotally mounted on the base element and has a holding position for holding the ski boot.
  • the holding element starting from the holding position in Skiquerides on both sides is pivotable, whereby a lateral safety release is made possible.
  • This front jaw comprises a housing, in the rear region of an intermediate piece is arranged. At this intermediate piece, a holding part for holding the front end of a ski boot sole is attached.
  • the housing has in its front region a bore in which a piston is displaceably guided in the longitudinal direction of the housing and acted upon by a spring with a rearwardly directed force.
  • the housing in a central region on a downwardly open recess. In this recess engages a part of the system, which points upwards from a mountable to a ski base plate.
  • the piston presses against a front surface of the plant part with an area from front to back, so that the plant part is pressed against the intermediate piece. Therefore, the intermediate piece rests on the wide rear side of the abutment part when the toe piece is in a hold position for holding a ski boot.
  • the housing can be pivoted together with the holding part to the system part with a lateral safety release. In such a pivoting movement and the intermediate piece is pivoted relative to the rear side of the system part, so that it is supported at the lateral edge of the wide rear side of the plant part is moved slightly backwards. As a result, the housing and the holding part are also moved backwards somewhat seen in the longitudinal direction of the ski.
  • the piston arranged in the housing is pivoted relative to the contact part with the pivoting movement.
  • the surface of the piston is tilted with respect to the forward-facing front surface of the abutment.
  • the piston in the housing is moved forward against the force of the spring. Accordingly, the front jaw can absorb energy in a shock on a ski shoe held in the toe until it comes to a lateral safety release.
  • the disadvantage of this front jaw is that the energy absorbed by the toe piece depends not only on the distance traveled by the piston and the force of the spring, but also on external forces acting on the holder and the housing. This is because the contact part is clamped between the intermediate piece and the piston and that the holding part, the intermediate piece and the housing relative to the contact part in the ski longitudinal direction are movable. As a result, a forward or backward force on the holding member or housing changes the energy consumable by the toe box.
  • the holding part, the intermediate piece and the housing during a rotational movement about the contact part are moved slightly backwards, whereby the holding part pushes backwards against the ski boot held in the ski binding and the ski boot accordingly causes a forwardly directed force on the holding part ,
  • the ski boot held in the ski binding also influences the energy that can be absorbed by the toe piece without any additional force.
  • This front jaw comprises a holding part for holding the front end of a ski boot sole, which is mounted pivotably about a vertical axis on a base part. In a front region in front of the vertical axis, this holding part has a flat surface.
  • the holding part is held in a holding position, in which the flat surface is aligned in the front region of the holding part parallel to the abutting surface of the piston.
  • 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.
  • ski center means a center of the ski as viewed in the ski direction, while the term “ski manifest” does not mean that it can move in relation to the ski.
  • ski manifest does not mean that it can move in relation to the ski.
  • 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.
  • the object of the invention is to provide a front jaw belonging to the technical field mentioned above, which allows both an optimally controlled lateral safety release as well as a compact design permits.
  • the toe piece comprises a coupling element, which is aligned essentially perpendicular to the pivot axis and is movable substantially radially relative to the radial bearing and thus relative to the base element and relative to the retaining element.
  • the at least two joint elements are coupled to one another via the coupling element.
  • a first of the at least two mating elements along the coupling element relative to the coupling element and radially to the radial bearing movably mounted and pressed by the first elastic member in the direction of the radial bearing, whereby the coupled via the coupling element at least two Stossetti with a substantially equal force against the Radial bearings are pressed.
  • the radial bearing and at least one of the at least two joint elements are shaped and cooperate in such a way that the retaining element can be pressed to the holding position by a force generated by the first elastic element and acting against the radial bearing by the stub elements.
  • the radial bearing can be a pin mounted in a journal bearing. But it may also be, for example, a ball or roller bearings or a differently designed radial bearing. It is only important that the radial bearing allows a pivoting movement of the holding element relative to the base element about the pivot axis and prevents a translational movement of the holding element relative to the base element perpendicular to the pivot axis.
  • the at least two joint elements can be arranged in different ways around the radial bearing.
  • the at least two joint elements can be pressed directly or indirectly via one or more other element against the radial bearing.
  • the first of the at least two joint elements which is mounted so as to be movable along the coupling element relative to the coupling element and radially to the radial bearing, may for example be movably mounted on the coupling element.
  • this first of the at least two joint elements can also not be movably mounted on the coupling element but on one or more other elements of the front jaw so that it can be moved radially along the coupling element to the radial bearing.
  • the holding element may be movably mounted on the holding element, so that it can be moved radially along the coupling element to the radial bearing.
  • the first of the at least two joint elements but also be movably mounted on the base element, so that it is movable along the coupling element radially to the radial bearing.
  • the first of the at least two die elements can be movably mounted on the coupling element, on the holding element or on the base element and also on one or more further elements of the front jaw, so that it is radially movable along the coupling element to the radial bearing.
  • the first of the at least two mating elements can be movably mounted along a linear path on the coupling element or on one or more other elements of the front jaw.
  • This linear path can be both straight and curved. However, it is at least partially aligned along the coupling element radially to the radial bearing and thus to the pivot axis.
  • the first of the at least two joint elements can also be mounted pivotably about a physical or a geometrical axis on the coupling element or on one or more other elements of the front jaw.
  • the physical or geometric axis is arranged such that pivotal movement of the first of the at least two mating elements results in a region of the first of the at least two mating elements remote from the physical or geometric axis being radially movable toward the radial bearing along the coupling element.
  • the first of the at least two joint elements is pivotally mounted both along a linear path and about a physical or geometric axis pivotally mounted on the coupling element or on another element of the front jaw.
  • the first of the at least two mating elements which is mounted so as to be movable along the coupling element radially to the radial bearing, may be one of the at least one of the at least two mating elements, which is shaped such that it interacts with the radial bearing in such a way that the holding element is moved by one of the generated first elastic element and acting through the stub elements against the radial bearing force can be pressed to the holding position.
  • the first of the at least two joint elements can also not be shaped such that it cooperates with the radial bearing in such a way that the retaining element can be pressed to the holding position by a force generated by the first elastic element and acting against the radial bearing by the stub elements.
  • the first of the at least two bluff elements differs from the at least one of the at least two bluff elements, which is shaped to be so with the radial bearing cooperates, that the holding element can be pressed by a force generated by the first elastic element and acting through the stub elements against the radial bearing force to the holding position.
  • the coupling element may be formed, for example, elongated or flat. In both cases, the coupling element is aligned substantially perpendicular to the pivot axis. If the coupling element is elongate, this means that a longitudinal axis of the coupling element is aligned substantially perpendicular to the pivot axis.
  • the first of the at least two joint elements which is mounted so as to be movable along the coupling element so as to be movable radially with respect to the pivot axis, is movable along the longitudinal axis of the coupling element.
  • the coupling element is designed to be flat, this means that a plane which is defined by the planar coupling element is aligned essentially perpendicular to the pivot axis.
  • the first of the at least two joint elements, which is mounted so as to be movable along the coupling element radially to the pivot axis is movable along the plane which is defined by the planar coupling element.
  • the first elastic element can be produced in one piece or in several pieces. If the first elastic element is made in several pieces, for example, there is the possibility that it comprises only one elastic part for generating the force by means of which the first of the at least two joint elements can be pressed in the direction of the radial bearing.
  • a multi-piece finished first elastic element may also comprise a plurality of elastic parts which may be arranged in parallel or in series to generate the force by which the first of the at least two joint elements can be pressed in the direction of the radial bearing.
  • the elastic element may be in each of the elastic parts, for example a spring, a steel spring, or even act of a made of an elastic material such as rubber element.
  • the first elastic element for example, be biased in the toe, that it draws two of its ends to each other by a tensile force.
  • the elastic element may, for example, also be prestressed in such a way that it presses two of its ends away from one another by a pushing force.
  • a first advantage of the solution according to the invention is that an optimally controlled lateral safety release is made possible. This is achieved, on the one hand, in that the retaining element is mounted on the base element so as to be pivotable about the pivot axis by the radial bearing and thus can not be moved radially relative to the pivot axis.
  • the optimally controlled safety release is achieved in that the coupling element is substantially radially movable to the radial bearing and that the at least two bluff elements are coupled together via the coupling element, wherein a first of the at least two bluff elements along the coupling element relative to the coupling element and radially movable to the radial bearing is mounted and can be pressed by the first elastic element in the direction of the radial bearing, whereby the coupled via the coupling element at least two mating elements with a substantially equal force against the radial bearing press.
  • the retaining element when an external force acts on the retaining element, the retaining element is securely supported by the radial bearing on the base element, while the coupling element and the at least two joint elements are not affected by this force, since they are movable relative to the radial bearing. Accordingly, the energy that can be absorbed by the toe until it comes to a lateral safety release, largely independent of external forces.
  • the inventive front jaw allows an optimally controllable safety release. This advantage is achieved regardless of whether the toe is used in an alpine ski binding or touring ski binding.
  • a second advantage of the inventive solution is that a compact construction of the front jaw is made possible because the at least two joint elements are arranged around the radial bearing and thus the mechanism, which allows a lateral safety release to the radial bearing can be arranged in a compact manner around the radial bearing ,
  • the at least two mating elements are pivotable about the pivot axis together with the holding element relative to the base element, when the holding element is pivoted about the pivot axis, or if the at least two mating elements at an equal angle to Swivel axis as the base element remain when the support member is pivoted about the pivot axis.
  • the front jaw for a ski binding comprises a base element, a radial bearing with a pivot axis which is arranged in a substantially vertically oriented, extending in the longitudinal direction of the plane, an elastic element, at least two joint elements, which are arranged around the radial bearing, and a holding element for holding a ski boot in the area of a ski boot tip.
  • the holding element is mounted by the radial bearing about the pivot axis pivotally mounted on the base element and has a holding position for holding the ski boot.
  • the holding element starting from the holding position in Skiquerides on both sides is pivotable, whereby a lateral safety release is made possible.
  • the front jaw comprises a coupling element, which is aligned substantially perpendicular to the pivot axis and substantially radially to the radial bearing and thus relative to the base element and relative to the holding element is movable.
  • the at least two joint elements are coupled to one another via the coupling element, wherein a first of the at least two joint elements is movably mounted along the coupling element relative to the coupling element and radially to the pivot axis and is pressed by the first elastic element in the direction of the radial bearing.
  • the coupled via the coupling element at least two joint elements are pressed with a substantially equal force against the radial bearing.
  • the radial bearing at least a positioning structure and at least one of the mating elements has a counter-structure to the at least one positioning structure.
  • the at least one stub element with its counter-structure is located on the corresponding at least one positioning structure, as a result of which the at least two stub elements are at a first distance from one another.
  • the at least one stub element is moved away with its counter-structure of the corresponding at least one positioning structure, whereby the at least two Stossetti are at a distance from each other, which is greater than the first distance, so that the holding element by a The force caused by the first elastic element is pressed to the holding position.
  • This has the advantage that the force caused by the first elastic element is optimally deflected into a restoring force, which biases the holding element towards the holding position.
  • This advantage is achieved independently of whether only one of the at least two joint elements has a counter-structure or whether more than one of the at least two joint elements has a counter-structure. If only one of the at least two mating elements has a counter-structure, the advantage is achieved independently of which of the at least two mating elements has this counter-structure.
  • the front jaw comprises more than one of the at least one positioning structure
  • these positioning structures are spatially delimited from one another by the fact that a respective stub element with its counterstructure can be located on each of the positioning structures.
  • a transition from a positioning structure to an adjacent positioning structure can be formed continuously, ie without structural separation.
  • a transition from a positioning structure to an adjacent positioning structure can also be formed by a structural separation. Accordingly, it is also irrelevant whether the positioning structures are made together from a single piece, or whether each of the positioning structures is made as a separate piece.
  • the at least one positioning structure may be formed, for example, as a recess or as a bulge. If more than one positioning structure is present, for example, each of the positioning structures can be formed as a recess or as a bulge. If it is a recess in a positioning structure, the counter-structure may be formed, for example, as a bulge. On the other hand, if a positioning structure is designed as a bulge, the counterstructure can be designed, for example, as an indentation.
  • a guide can be formed by the shape of the at least one positioning structure and the counter-structure which, depending on the rotational position of the holding element about the pivot axis allows a certain minimum distance between the at least one Stosselement with the counter-structure and the pivot axis. This minimum distance can be smallest, when the holding element is in the holding position and become larger, the farther the holding element is moved away from the holding position.
  • the at least two joint elements are coupled to one another via the coupling element and pressed against the radial bearing, it can be achieved with such a guide that the at least two joint elements are at a first distance from each other when the retaining element is in the holding position, and that the at least two mating elements are at a distance from one another which is greater than the first distance when the holding element is moved away from the holding position.
  • the at least one positioning structure can also be embodied differently than indentation or as a bulge.
  • the counter-structure may also be designed differently than a bulge or as an indentation.
  • the at least one positioning structure and the counter-structure may be formed as a flat surface.
  • the at least one positioning structure and the or the Stossieri may be arranged with a counter-structure such that rests in the holding position of the holding element, the at least one positioning with its planar surface area on the flat surface of the counter-structure of the corresponding Stosselements.
  • the holding element is pivoted away from the holding position about the pivot axis, then the flat surface of the counter-structure is tilted relative to the respective flat surface of the positioning structure.
  • This form the at least one positioning structure and the counter-structure a guide which, depending on the rotational position of the holding element about the pivot axis allows a certain minimum distance between the at least one Stosselement with the counter-structure and the pivot axis. This minimum distance is smallest when the holding element is in the holding position and becomes larger the farther the holding element is moved away from the holding position.
  • the at least two joint elements are coupled to one another via the coupling element and pressed against the radial bearing, it is achieved with such a guide that the at least two joint elements are at a first distance from each other when the retaining element is in the holding position, and that the at least two mating elements are at a distance from one another which is greater than the first distance when the holding element is moved away from the holding position.
  • the number of the at least one positioning structure is preferably equal to or greater than the number of die elements with a counter-structure. This makes it possible that each mating element can be positioned with its counter-structure on a positioning structure. This has the advantage that the force generated by the first elastic element is optimally used to push the holding element in the holding position. Alternatively, there is also the possibility that the number of at least one positioning structure is smaller than the number of die elements with a counter-structure. Such an alternative may have the advantage that the manufacture of the toe piece is easier because fewer positioning structures are needed.
  • preferred embodiments of the front jaw can also be designed differently. In the following it will be shown on the basis of advantageous features how such other preferred embodiments can be formed. Of course, however, the abovementioned, preferred embodiment with the at least one positioning structure and the counter-structure may also comprise one or more of these advantageous features.
  • the holding element comprises a rigidly formed region, which has on both sides to the rear reaching ends which are shaped so that they in the
  • Holding position of the holding element laterally grip around a ski boot held in the toe piece.
  • This has the advantage that the holding element in the holding position laterally supports the ski boot held in the front jaw with the rigidly formed area on both sides. This allows the ski boot to be held optimally in the toe.
  • the rigidly formed area is formed from a single piece or from a plurality of rigidly connected individual pieces. Regardless, there is the possibility that further movable elements are arranged on the rigidly formed area.
  • rollers may be mounted on the rigidly formed area, which facilitate movement of the ski boot held in the toe piece away from the toe piece in the event of a lateral safety release by reducing a possible frictional resistance between the holding element and the ski boot.
  • the holding element does not comprise such a rigidly formed area.
  • the holding element comprises an upper portion, which extends slightly rearwardly to at least partially surround the sole of a ski boot held in the toe piece.
  • another element of the front jaw comprises, as the retaining element, a region which extends somewhat rearward in order to at least partially surround the sole of a ski boot held in the front jaw.
  • the holding element and one or more further elements of the front jaw each comprise an area which extends somewhat rearward to at least partially surround the sole of a ski boot held in the toe piece.
  • no element of the front jaw comprises an area which extends somewhat backwards in order to at least partially surround the sole of a ski boot held in the front jaw.
  • an element of the front jaw can have a region reaching backwards, which engage in a recess in the ski boot and thus follow the ski boot can support up.
  • the coupling element is movable in a plane perpendicular to the pivot axis relative to the radial bearing.
  • This has the advantage that the coupling element is movable not only radially to the radial bearing, but in all directions in the plane perpendicular to the pivot axis. Accordingly, the coupling element can act compensating when an external force acts on the retaining element. This makes it possible for the at least two impact element to press against the radial bearing substantially unaffected by the external force. Accordingly, this allows a reliable controllable lateral safety release of the toe piece.
  • the coupling element is movable only substantially radially to the radial bearing.
  • the first elastic member has first and second ends, wherein the first end of the first elastic member is located farther from the radial bearing than the second end of the first elastic member, and wherein the first end of the first elastic member is supported against the coupling member while the second end of the first elastic member is supported against the first of the at least two thrusting members, which is movably supported along the coupling member relative to the coupling member and radially to the radial bearing.
  • This has the advantage that the force produced by the first elastic element can be optimally transmitted to the first of the at least two joint elements and to the coupling element. This allows optimal control of a lateral safety release.

  • the first end of the first elastic element is supported relative to a first end of the coupling element.
  • the first end of the coupling element is a longitudinal end of the coupling element, if the coupling element is elongated. If, however, the coupling element has a substantially triangular, quadrangular or pentagonal shape, then the first end of the coupling element is located at a corner of the coupling element. If, however, the coupling element is of star-shaped design, the first end of the coupling element is located at a tip of a star-shaped serrated point.
  • the coupling element has a disk-like shape with a rounded edge
  • the first end of the coupling element is located at a location on the edge of the coupling element.
  • this has the advantage that the space around the radial bearing can be optimally utilized, since the elastic element can extend from the first of the at least two joint elements to the first end of the coupling element. Accordingly, a larger and thus stronger elastic element can be used per unit volume of the toe. This allows a compact construction of the front jaw, wherein the front jaw for its size can absorb a relatively large amount of energy until it comes to a safety release.
  • the first end of the first elastic element is supported relative to a region of the coupling element, which is offset from the first end of the coupling element inwardly toward the radial bearing.
  • the first elastic element not with respect to the coupling element, but with respect to another element of the Front jaw such as the support member or the base member is supported.
  • a second mating element of the at least two mating elements is movably mounted along the coupling element relative to the coupling element and radially to the radial bearing, wherein the front jaw comprises a second elastic element, by means of which this second mating element can be pressed against the radial bearing.
  • the second stub element can for example be movably mounted on the coupling element.

  • the toe piece has two elastic elements, which both contribute to the at least two mating elements coupled to one another via the coupling element being pressed against the radial bearing with a substantially equal force. Accordingly, the force with which the at least two joint elements are pressed against the radial bearing can be increased by the second elastic element. As a result, the size of the toe piece can absorb more energy until a lateral safety release occurs.
  • a second mating element of the at least two mating elements is movably mounted along the coupling element relative to the coupling element and radially to the radial bearing and the toe piece comprises a second elastic element

  • first inventive toe 1 can also when in the Figures 6a and 6b shown toe 51 a height of the holding member 52 are adjusted relative to the base member 58.
  • a mechanism is also provided with a screw, as it is explained in detail for the first inventive toe 1. This mechanism, however, is in the Figures 6a and 6b can not be seen.
  • the coupling element can be formed in the second embodiment, for example, as a spindle. It may be aligned in the longitudinal direction of the ski or in the direction of the ski. In addition, it may be movably mounted in the ski longitudinal direction or in the ski direction. The same is true for the spindle according to the first embodiment, which can be formed as the coupling element according to the second embodiment.
  • the front jaw as described may include two stucco elements or even more than two stamper elements. Moreover, in both embodiments, only one or two of the stub elements can be movably mounted along the coupling element.
  • the coupling element is mounted on the holding element.
  • the coupling element can also be mounted on the base element.
  • such a modification may, for example, be such that the coupling element is movably arranged in the longitudinal direction of the ski on the base element, while the pin is arranged on the retaining element.
  • the pin is pivotally mounted about the pivot axis in a counterpart arranged on the base element. Therefore, in this embodiment, when the holding member is pivoted about the pivot axis, the flat flattened portion on the front side of the pin is also pivoted with respect to the base member.
  • this area is tilted relative to the flat, front edge of the opening in the coupling element, whereby the coupling element is pushed forward relative to the base element.
  • the spring is also tensioned, whereby an energy absorption is made possible by the toe.
  • the two stops, springs, stamper and the spindle can be arranged on the base element. If the pin is not arranged on the base element, but on the holding element and is pivotally mounted in a counterpart on the base element about the pivot axis, so the push elements can press against the pin.
  • both the two stops, the springs, the Stossetti, the spindle and the pin are mounted on the base element, so the two Stossrion can press against the counterpart on the holding element, in which the pin is rotatably mounted.
  • the counterpart on the holding element should have a shape such that the distance is increased by at least one of the two Stoss institute to the pivot axis when the holding element is pivoted away from the holding position.
  • the stub elements and the element of the radial bearing, with which cooperate the Stossiata can be shaped differently. It is not necessary that one or both of the male members and the corresponding member of the radial bearing have planar surfaces as in the above-described embodiments, which are mutually tilted when the retainer is moved away from the holding position.
  • the one or both stub elements and the corresponding element of the radial bearing can for example also have a bulge and indentation. What is important about their shape is that at least one of the mating elements is moved away from the axis of rotation when the holding element is pivoted away from the holding position. By this movement of the or the push elements one or more springs or elastic elements can be compressed or pulled apart. As a result, energy can be absorbed by the toe piece during a pivoting movement of the retaining element.
  • a mechanism which allows a safety release in the reverse direction.
  • such a mechanism may for example be given by the fact that the holding element is rotatably mounted not only about the pivot axis on the base element, but also slightly about a horizontal, substantially aligned in the cross direction axis. This can be achieved, for example, by virtue of the fact that the counterpart, with which the holding element is mounted on the pin, allows the holding element to rock about a horizontal axis which is oriented substantially in the direction of the ski.
  • the mating elements should be designed such that they hold the holding element in the holding position in a predetermined orientation about the horizontal, aligned substantially in the direction of the cross axis.
  • the support member When an upward force acts on the ski boot or a downward force acts on the toe or ski, the support member can be pivoted about the horizontal, substantially cross-machine directional axis until the ski boot is released from the toe. During this pivoting movement The two jaw elements should be pressed apart so that the front jaw can absorb energy until it comes to a safety release in the reverse direction.
  • the two laterally arranged Stoss comprise not only in the ski longitudinal direction aligned, have vertical, flat surfaces, but also surround the pin at the front and rear something to support the pin front and rear.
  • the two die elements are pressed apart when the holding element with the two die elements is pivoted about the horizontal, oriented substantially in the direction of the cross grain axis with respect to the pin.
  • no adjustment of the two Stossieri is required, since they are forced apart due to their vertical extent, when the holding element is pivoted about a horizontal, aligned substantially in the direction of the cross axis relative to the pin.
  • a front jaw is provided which allows both an optimally controlled lateral safety release and permits a compact design.
