Definitions

  • the present invention relates to a binding system for a touring ski binding comprising a toe piece device and a heel piece device for receiving a ski boot.
  • Ski bindings for touring skis are primarily distinguished by their ability to switch between an ascent mode and a descent mode, unlike standard ski bindings.
  • ascent mode only the front part of the ski boot is fixed to the ski, allowing the rear part of the boot to be lifted and placed on the ski.
  • the front of the boot rotates around a horizontal axis of a binding bar, perpendicular to the ski's length.
  • descent mode both the front and rear of the ski boot are firmly fixed to the ski.
  • Strap bindings are characterized by the fact that the ski boot is clamped between the toe and heel pieces in both the downhill and uphill positions.
  • the toe and heel pieces are mounted on a strap, with the front part of the strap fixed to the ski in both the uphill and downhill positions.
  • the front part of the strap In the uphill position, the front part of the strap can rotate around an axis running horizontally and perpendicular to the ski's longitudinal axis.
  • the rear end can be fixed to the ski in the downhill position and lifted off the ski in the uphill position.
  • the bridge results in the aforementioned disadvantages of a higher standing height and a comparatively higher weight.
  • Pin binding systems can be divided into a toe unit and a heel unit. In the ascent position, the ski boot is only rotatable by the toe unit around a pivot axis running horizontally and perpendicular to the ski's longitudinal axis. Pin systems known from the prior art have the significant disadvantage that the lateral release behavior, in which the ski boot can release laterally from the binding under increased force in downhill mode, is impaired by the pins penetrating the ski boot.
  • the US 5,066,036 shows a ski binding system.
  • the US 6,467,796 B1 shows a ski binding assembly.
  • the US 11,173,381 B2 shows a toe piece for a ski binding.
  • the EP 0 768 103 A1 shows a shoe binding unit.
  • the FR 2,172,925 shows a device for attaching a boot to a ski.
  • a binding system for a touring ski binding comprising a toe piece device and a heel piece device for receiving a ski boot, wherein the ski boot has a heel part and a forefoot part, wherein at least one bar is arranged in or on the forefoot part, the axis of the bar being perpendicular to the longitudinal axis of the boot, the longitudinal axis of the boot extending from the heel part to the forefoot part, wherein the toe piece device comprises a holding device with a bracket and a locking system, wherein the bracket has a hook-shaped receptacle for receiving the bar of the ski boot, which is oriented opposite to the longitudinal axis of the boot, wherein the bracket at least partially encompasses the bar and thus receives the bar of the ski boot, wherein the locking system is suitable for locking the bar of the ski boot rotatably in the bracket about the bar axis, wherein the heel piece device has a lever mechanism suitable for fixing the heel part of the ski boot, wherein in an
  • the touring ski binding can be mounted on a ski, for example using a screw connection.
  • the ski surface normal which runs perpendicular to the boot's longitudinal axis and orthogonal to the binding's web axis, is perpendicular to the ski surface. Therefore, the relative positions of the various parts of the touring ski binding are described below based on these axes.
  • the ski boot has a heel section and a forefoot section.
  • the heel and forefoot sections are positioned on the ski boot according to the anatomy of a human foot. Specifically, the heel and forefoot sections refer to the outermost parts of the ski boot. Accordingly, the longitudinal axis of the boot runs from the heel to the forefoot, thus corresponding to the typical walking direction of a human.
  • the ski boot can have a particularly robust edge at the heel (and/or forefoot) that is suitable for transmitting a force, especially a longitudinal holding force, along the boot's longitudinal axis.
  • This edge can also extend away from the heel of the ski boot in the opposite direction to the boot's longitudinal axis, in order to provide both a large surface area for leverage and various surfaces for transverse holding forces, particularly transverse holding forces acting orthogonally to the boot's longitudinal axis and parallel to the ski surface normal.
  • At least one rib is arranged in or on the forefoot part of the ski boot.
  • the rib is preferably a cylindrical component whose cylinder axis runs perpendicular to the longitudinal axis of the boot.
  • the cylindrical design of the rib makes it particularly easy to rotate the ski boot within the toe piece. This easy rotation allows the ski to be guided comfortably and with minimal impact on the joints under the foot or boot during the natural walking motion. This results in a more stable gait on varied terrain and thus increased safety.
  • the toe piece has a finite length, typically less than the width of the forefoot.
  • the toe piece can be fully or partially embedded in the sole of the ski boot, or it can lie entirely outside the sole and be attached to the ski boot, for example, by a reinforced toe piece retaining structure. Translation along the toe piece axis is limited in the toe piece assembly either by the sole or by the toe piece retaining structure of the ski boot. Ideally, the ski boot held in the toe piece assembly should not be able to move translationally along the toe piece axis, for example, it should not be able to shift.
  • the hook-shaped mount of the holder can be adapted to the curve or geometric shape of the bridge, thus enabling a positive-locking contact between the bridge and the holder. This allows for a particularly stable and rigid connection between the ski boot and the toe piece, resulting in excellent ski control.
  • the bracket encompasses at least part of the bridge.
  • a hook forming the hook-shaped receptacle is only suitable for providing a transverse holding force and a longitudinal holding force.
  • the holder only needs to extend from the top of the shank to the front of the shank (viewed along the boot's longitudinal axis in the plane formed by the boot's longitudinal axis and the ski surface normal). This already generates a transverse holding force parallel to the ski surface normal and also a longitudinal holding force along the boot's longitudinal axis.
  • a holding force along the negative ski surface normal is provided by the ski surface itself, so the holder does not need to encompass the lower part of the shank.
  • the bridge is therefore received by the holder when the translation of the ski boot along the positive ski surface normal and along the boot's longitudinal axis is prevented.
  • the hook-shaped receptacle for holding the ski boot's shank is aligned opposite to the boot's longitudinal axis.
  • the cleat Regardless of the shape of the cleat, at least translation of the ski boot along its longitudinal axis can be prevented, as the hook acts as a mechanical barrier. Furthermore, translation of the ski boot against the direction of the ski surface normal can be prevented. This can be achieved either through the shape of the cleat or through the locking system.
  • the holder with hook-shaped receptacle can also be designed in the form of a hook system with an opening.
  • the locking system is positioned in front of the holder on the ski, along the longitudinal axis of the boot.
  • the holder prevents the cleat from moving against the boot's longitudinal axis. Together with the holder's secure grip, this prevents any movement of the ski boot perpendicular to the cleat axis.
  • the system also prevents movement of the ski boot along the cleat axis. However, the ski boot, once held and locked in the holder, can still be rotated around the cleat axis.
  • the heel piece device incorporates a lever mechanism designed to secure the heel of the ski boot.
  • the lever mechanism can exert a longitudinal holding force on the ski boot, pressing it along its longitudinal axis into the toe piece device.
  • a transverse holding force that presses the heel of the ski boot towards the ski surface is also advantageous.
  • a lever mechanism can mean that the mechanism comprises at least two components that are movably attached to each other and can be moved relative to each other to exert a holding force on the ski boot.
  • a movable attachment can mean that the components of the lever mechanism can be rotated and/or shifted.
  • the toe piece In downhill mode, the toe piece is open and the heel piece is closed.
  • An open toe piece means that only the holder can accommodate the ski boot's heel piece, but the locking mechanism does not allow the heel piece to rotate.
  • An open toe piece therefore allows the heel piece to be inserted into or removed from the holder. This makes it possible, especially in the event of a fall in downhill mode, to release the boot from the binding, particularly from the toe piece.
  • the locking system is permanently attached to the ski and the bracket is movable.
  • the front jaw device further comprises a front jaw lever mechanism, wherein the holder is movable by means of the front jaw lever mechanism.
  • a toe-jaw lever mechanism can exert a force along or against the longitudinal axis of the shoe by rotating components of the mechanism around their mounting points.
  • the toe-jaw lever mechanism thus redirects the (rotational) forces acting on the lever into a transverse force, preferably a transverse holding force.
  • a front jaw lever mechanism allows the holder to be moved towards the locking system by actuating a lever.
  • the lever of the front jaw lever mechanism can have two positions, so that a closed and an open state of the front jaw device can be achieved.
  • the front jaw device further comprises a front jaw spring mechanism, wherein the holder is displaceable by means of the front jaw spring mechanism.
  • the bracket can also be moved by a front jaw spring mechanism.
  • the front jaw assembly can be pre-tensioned by the front jaw spring mechanism.
  • a spring can be positioned between the locking system and the bracket, allowing the spring to push the bracket and locking system away from each other. However, it is also possible for the spring to push the bracket and locking system towards each other.
  • a lever position of the toe piece lever mechanism can bring the toe piece into a closed position.
  • This toe piece lever mechanism can then be used, for instance, as a safety release mechanism, since the spring is pre-tensioned by the closed position of the toe piece.
  • the spring would push the locking system and the retainer away from each other.
  • the retainer can be pushed away from the locking system by the toe piece spring mechanism, allowing the bar and ski boot to release from the toe piece. This allows for a safety release, particularly in ascent mode.
  • the spring can be positioned so that the holder and the locking system are moved relative to each other.
  • the spring is under tension when the lever position of the toe piece lever mechanism is in the closed position. This allows the spring to act as a safety release in both downhill and uphill modes. If a force in the direction of the boot's longitudinal axis exceeds a predefined threshold, such as during a fall, the holder is pushed away from the locking system, and the toe piece and ski boot can be released from the toe piece assembly.
  • bracket and locking system This allows the bracket and locking system to be set to a predefined distance, so that the bracket can lock the bridge in a rotatable manner.
  • the locking system comprises a locking plate configured to at least partially cover the hook-shaped receptacle of the bracket. This allows the locking mechanism, or the element that locks the bridge and restricts its translational degrees of freedom, to be mounted separately from the locking system and its underlying mechanics.
  • the shank of the ski boot is offset along or against the longitudinal axis of the boot in ascent mode compared to descent mode. This can be achieved, in particular, by positioning the retainer behind the locking system in the direction of the boot's longitudinal axis when the toe piece device is in the open position.
  • the different positions of the ski boot relative to the ski allow for better balance in downhill and uphill modes, thus reducing the risk of injury and increasing the enjoyment of skiing and climbing.
  • Figure 1 shows an overview of the binding system 1 for a touring ski binding.
  • the binding system comprises a toe piece 2 and a heel piece 3 for holding a ski boot 4.
  • the binding system 1 is mounted on a ski 10, for example by means of a screw connection.
  • the surface of the ski on which the binding system is mounted has a surface normal, which is called the ski surface normal Z.
  • the ski boot 4 has a heel section 40 and a forefoot section 42.
  • the longitudinal axis X of the boot extends from the heel section 40 to the forefoot section 42.
  • the ski boot 4 also has a rib 44 in the forefoot section 42.
  • the rib 44 is preferably cylindrical and extends, in particular with its circular cross-section, perpendicular to the plane formed by the ski surface normal Z and the longitudinal axis X of the boot. Accordingly, the axis of symmetry of the rib 44 is the rib axis Y, which extends into the plane of the ski surface.
  • the bridge 44 is arranged such that it lies completely beneath the sole of the ski boot 4.
  • the bridge 44 can also be arranged in other positions on the forefoot part 42, as shown in the Figures 2A-2E shown.
  • FIG. 2A shown that the bridge 44 is located entirely below the sole.
  • Figure 2B It has been shown that the bridge 44 is partially located below the sole.
  • Figure 2C It has been shown that the bridge 44 is fully integrated into the sole.
  • Figure 42 shows that the bridge is partially integrated into the front end of the forefoot section.
  • the bridge can also be fully integrated into the front end of the forefoot section (not shown).
  • Figure 2E It is also shown that the bridge is arranged in front of the front end of the forefoot section 42. Depending on the design, particularly ergonomic driving and climbing characteristics of the binding system can be achieved.
  • the front jaw assembly 2 of the Figure 1 further comprises a holding device 20, which includes a bracket 21 and a locking system 27, and which is shown in greater detail in the Figures 3A-4D is shown.
  • the holder 21 of the toe piece device 2 has a hook-shaped receptacle 22, which is formed as a hook system 23 with an opening 24, the opening 24 pointing opposite to the longitudinal axis X of the boot.
  • the opening 24 of the hook system 23 can partially encompass the bar 44 of the ski boot 4, and thus the hook system 23 can receive the bar 44 of the ski boot 4.
  • the opening 24 is U-shaped, so that a secure hold of the bar 44 in the hook system 23 is ensured.
  • the toe piece device 2 has a locking system 202 with which the bar 44 of the ski boot 4 can be rotatably locked in the hook system 23.
  • a rotatable locking means that translation of the bar 44 is to be prevented.
  • the hook system 23 can, for example, prevent translation in the direction of the boot's longitudinal axis X and in the direction of the ski surface normal Z. Simultaneously, translation against the ski surface normal Z can be prevented by the ski 10 itself or by the hook system 23.
  • the locking system 27 can prevent translation of the bar 44 against the direction of the boot's longitudinal axis X.
  • the translational degrees of freedom in and against the bar axis Y are realized by the bar 44 itself and its attachment in or to the sole. Accordingly, the bar 44 retains only one rotational degree of freedom about the bar axis Y.
  • the rotational degree of freedom is not restricted by the hook system 23, but rather granted.
  • the locking mechanism of the locking system 27 is characterized by the fact that the hook system 23 is displaced relative to the locking system 27.
  • Fig. 3A The length ⁇ x of the relative displacement along the shoe's longitudinal axis X is shown.
  • the locking system 27 comprises a locking plate 28, which is arranged between the locking system 27 and the hook system 23.
  • the locking plate 28 can enable a particularly advantageous rotatable locking action, for example, if a particularly stable locking action or a particularly low-friction locking action is enabled.
  • the locking plate 28 can also be formed as a single unit with the locking system 27 ( Figures 4A to 4D ) or have a curvature corresponding to the bridge 44, so that the bridge 44 can be held in a form-fitting manner by the hook system 23 and the locking system 27 (not shown).
  • FIG. 3C and 3D Further embodiments of the front jaw device 2 are shown.
  • the locking system 27 is fixedly attached to the ski 10, while the hook system 27 can be moved.
  • a front jaw lever mechanism 29 and a front jaw spring mechanism 26 are shown, by means of which the hook system 23 can be moved.
  • the acting force typically comprises two components: a force Fx in the direction of the shoe's longitudinal axis X, and a force Fz in the opposite direction to the ski surface normal Z, as shown in Figure 5B
  • the force Fx presses the ski boot 4, or rather its heel piece 44, into the hook system 23, thus fixing the ski boot 4 in the direction of the boot's longitudinal axis X.
  • the force Fz pushes the ski boot 4, or rather the heel piece 40, towards the ski 10, so that the heel piece 40 cannot be lifted off the ski 1.
  • the pressure exerted by the lever mechanism 30 acts on the heel part 40 of the ski boot, so that a force acts along the longitudinal axis X of the boot and the bridge 44 is pressed into the hook system 23 of the toe piece device 2.
  • the ski boot 4 is thus secured against translation against the longitudinal axis X of the boot by the lever mechanism 30.
  • the buttock device 3 can have a safety release 306, as shown in the Figures 5A to 5C shown. This allows the lever mechanism 30 to open, for example, under a predefined force, so that the heel part 40 of the ski boot can be removed from the heel piece device 3.
