Definitions

  • the invention relates to a front automaton for a touring ski binding.
  • This front automaton comprises two levers arranged laterally and opposite one another as seen in the longitudinal direction of the ski, each with a holding means for holding a ski boot in a toe area of the ski boot.
  • the two levers are each mounted so as to be pivotable about an axis such that the holding means are moved in a transverse direction of the ski when the levers pivot about these axes.
  • the front automaton has a release position in which the two holding means are at a first distance from one another. It also has a locking position in which the two holding means are at a second distance from one another, which is smaller than the first distance.
  • ski bindings can be divided into piste bindings, which are only used for downhill skiing and skiing on ski lifts, and touring bindings, which are also used for walking on skis, in particular for climbing with the help of climbing skins attached to the skis. While the former only have to ensure reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must also be able to be moved from the downhill position into an ascent position for climbing, in which the ski boot can be pivoted about an axis in the transverse direction of the ski and lifted off the ski at the heel in order to enable a joint movement between the ski boot and the ski for walking.
  • Touring ski bindings can be divided into two types.
  • One type includes a ski boot carrier that can be pivoted relative to the SI ⁇ i, to which the ski boot is held by binding jaws.
  • a representative member of this type of touring ski binding is, for example, the EP 0 754 079 B1 (Fritschi AG ).
  • the second type of touring ski binding does not include such a ski boot carrier.
  • the ski boot is pivotally mounted in a toe area on the sole in a front automatic mechanism that is fixed to the ski.
  • the heel automatic mechanism is also firmly attached to the SI ⁇ i at a distance from the front automatic mechanism that is adapted to the length of the SI ⁇ i boot sole and locks the boot in the heel area in the downhill position.
  • Ski boots suitable for this type of binding typically have two lateral recesses in the toe area for pivoting mounting in the front automatic mechanism. In the heel area, recesses that are open to the rear are formed on the sole of the boot, into which the heel automatic mechanism can engage. In addition, such ski boots have a stiff or only slightly flexible sole. In the latter case, the ski boots can be designed to be flexible, for example in the ball area of the foot.
  • a (fictitious) SI ⁇ i is often used as a reference system, assuming that the binding is mounted on this SI ⁇ i.
  • This practice is adopted in the present text.
  • the term "longitudinal direction of the ski” means along the alignment of the longitudinal axis of the ski.
  • "ski parallel” for an elongated object means aligned along the longitudinal axis of the ski.
  • the term “ski parallel” means aligned parallel to the gliding surface of the ski.
  • cross direction of the ski means a direction transverse to the longitudinal direction of the ski, which does not have to be oriented exactly at right angles to the longitudinal axis of the ski.
  • ski center in turn means a center of the ski seen in the cross direction of the ski, while the term “ski fixed” means not movable relative to the SI ⁇ i. It should also be noted that terms that do not contain the word “ski” also refer to the reference system of the (fictitious) ski.
  • front, back, “top”, “bottom” and “side” refer to the “front”, “back”, “top”, “bottom” and “side” of the ski.
  • horizontal and “vertical” refer to the ski, where “horizontal” means lying in a plane parallel to the ski and “vertical” means oriented perpendicular to this plane.
  • a touring ski binding of the second type introduced above is in the EP 0 199 098 A2 (Bartel ) and is sold under the brand name Dynafit.
  • the front part of this system comprises two angle levers, which are arranged opposite one another in the transverse direction of the ski and are each pivoted about an axis running in the longitudinal direction of the ski.
  • the two angle levers each have an upwardly directed arm and a sideways directed arm, which are arranged at right angles to one another.
  • the upwardly directed arms each comprise a truncated cone or hemispherical pin pointing towards the middle of the ski, which can engage in recesses provided for this purpose in the toe area of a ski boot.
  • the sideways directed arms of the angle levers point towards the middle of the ski like the pins, but are operatively connected to one another via a spring device. Since the two angle levers are spring-loaded by the spring device via the sideways directed arms, they can be moved downwards and upwards by overcoming a dead center position in which the two sideways directed arms are aligned in a linear extension to one another. snap upwards. When the sideways arms are snapped downwards, the upwards arms are pivoted together. When the sideways arms are snapped upwards, on the other hand, the upwards arms are pivoted apart. Accordingly, the pins for holding a ski boot are closer together in the first case and further apart in the second case.
  • a ski boot can be held or pivoted between the two angle levers using the pins.
  • This position of the front part of the binding is therefore a holding position.
  • the holding means are far enough apart for the ski boot to be released. Accordingly, this position of the front part of the binding is a release position.
  • the EP 0 199 098 A2 (Bartel ) has an opening lever which can be pivoted about an axis aligned in the transverse direction of the ski and which surrounds the connection of the two laterally aligned arms of the angle levers at the top and bottom.
  • This opening lever By operating this opening lever, the laterally aligned arms of the angle levers can be pushed upwards, where they snap into the free position.
  • the laterally aligned arms of the angle levers can also be pushed downwards, where they snap into the fixed position.
  • the ski boot can be released from the ski binding system without using the release lever. To do this, the ski boot is first released from the heel mechanism and then from the front part of the binding. In the event of a frontal fall, the ski boot is released upwards by the heel mechanism and tilted forwards in the front part of the binding. If the force acting forwards or upwards on the ski boot is sufficiently large, the ski boot is also torn from the front part of the binding by overcoming the force acting on the two angle levers. In the event of a sideways fall, the ski boot is released sideways by the heel mechanism and tilted forwards by a force located in the toe area of the ski boot. The ski boot is released from the front part of the binding by rotating, overcoming the force acting on the angle levers.
  • Both the binding front part according to the EP 0 199 098 A2 (Bartel ) as well as the binding front part according to the WO 2009/121187 A1 (G3 Genuine Guide Gear Inc.) have the disadvantage that release is uncontrolled. When released, the two angle levers are pushed apart in an undefined manner by a force (or torque) acting on the ski boot, which releases the ski boot from the front part of the binding.
  • This front automaton also includes two angle levers, each of which includes two arms arranged essentially at right angles to one another.
  • the first arms of these angle levers also include a truncated cone or hemispherical pin pointing towards the middle of the ski for holding a ski boot.
  • the second arms of these angle levers are also aligned laterally towards the middle of the ski, pointing towards one another.
  • the two angle levers are pivotally mounted about vertical axes, with the axes in front of the toe area of the ski boot.
  • the second arms of the angle levers are not directly connected, but each end engages in a lateral notch of a pivot lever aligned in the longitudinal direction of the ski.
  • This pivot lever can be moved in the longitudinal direction of the ski, with the ends of the second arms of the two angle levers being guided in the lateral notches. Accordingly, when the pivot lever is moved, the two angle levers are pivoted towards or away from each other, which allows the front automatic device to be transferred from the release position to the holding position and back.
  • the pivot lever In addition to being able to move in the longitudinal direction of the ski, the pivot lever is mounted on the front automatic device so that it can pivot around a vertical axis, but is pressed into a parallel alignment by two springs. If a force acts laterally on the ski boot, the outer of the two angle levers can be pushed outwards by pivoting the pivot lever slightly to the side against the spring force until the angle lever is released from the lateral notch in the pivot lever. At the same time, the inner angle lever is pivoted slightly inwards by the pivoting movement of the pivot lever, following the outer angle lever.
  • the front automatic device to WO 2007/010392 A2 (SI ⁇ i Trab SRL) a lateral release, where the ski boot support is first loosened and, as soon as the outer angle lever is released, it is released completely.
  • the front automat also enables a frontal release, which, however, is just as uncontrolled as with the binding front parts according to the EP 0 199 098 A2 (Bartel ) and the WO 2009/121187 A1 (G3 Genuine Guide Gear Inc.) .
  • binding front parts and front automatics offer only limited safety for the skier.
  • the two binding front parts offer EP 0 199 098 A2 (Bartel ) and the WO 2009/121187 A1 (G3 Genuine Guide Gear Inc.)
  • the front automatic device according to the WO 2007/010392 A2 offers a limited lateral safety release.
  • the two angle levers are continuously spread and thus opened until the outer angle lever is completely released and pivoted away. The ski boot is already partially released while the angle levers are being spread.
  • the front automatic also offers WO 2007/010392 A2 (SI ⁇ i Trab SRL) no frontal release. It only allows the ski boot to be ripped forwards or upwards out of the front automatic system if sufficient force is applied. This is why these well-known front automatic systems offer little safety for a skier.
  • the object of the invention is to create a front automatic device belonging to the technical field mentioned at the beginning, which increases the safety for a skier.
  • the holding means are pins which are arranged on the respective lever in such a way that they point with a free end towards the middle of the ski starting from the respective lever.
  • the front automaton has a safety release position.
  • the front automaton also comprises a forced control on which the two levers are mounted in the holding position, so that the two levers are coupled within a dynamic range and can be moved in the transverse direction of the ski, and the two holding means are coupled at a second distance from each other and moved on a dynamic path in the transverse direction of the ski, whereby a ski boot held in the front automaton can be moved together with the two holding means in the holding position on the dynamic path in the transverse direction of the ski, whereby the front automaton can absorb energy without the ski boot being released from the front automaton.
  • the coupled movement of the two levers along the dynamic range can be, for example, a pivoting movement of the two levers around the axes.
  • the coupled movement of the two levers along the dynamic range can also be a linear movement along a linear path, which corresponds to a translational movement of the two levers, in which the two levers are coupled and moved in the transverse direction of the ski.
  • the coupled movement of the two levers along the dynamic range can also be a linear movement along a linear path, which corresponds to a combination a translational movement and a pivoting movement of the two levers, in which the two levers are coupled and moved in the transverse direction of the ski and pivoted about the axes.
  • the dynamic range can be limited on one or both sides by a stop, which stops at least one of the two levers and prevents it from moving further.
  • the dynamic range can be limited on one or both sides by the fact that from a certain position the two levers can no longer be moved coupled, but can be moved decoupledly.
  • the dynamic range for one of the levers can be limited by a stop and for the other lever to be limited by the fact that from a certain position it can be moved decoupledly.
  • the type of limitation for the two levers can also depend on the side of the dynamic range.
  • the dynamic range on a first side is limited by a stop for a first of the two levers and for a second of the two levers it is limited by the fact that from a certain position it can be moved decoupledly.
  • the dynamic range on a second side for the first lever can be limited by the fact that it can be moved in a decoupled manner from a certain position, while the dynamic range on the second side for the second lever is limited by a stop.
  • a ski boot held in the front automatic device can be moved along the dynamic path in the transverse direction of the ski together with the two holding means in the holding position, whereby the front automatic device can absorb energy without the ski boot being released from the front automatic device.
  • This is advantageous when skiing and possibly in the event of a fall, as impacts can occur on the ski boot or the ski boot, which should not cause the ski boot to be released from the front automatic device.
  • the energy that the front automatic device can absorb can be specified by adjusting the length of the dynamic path and/or a resistance force that must be applied for the movement. Accordingly, a controlled A safety release should be provided which is triggered if the energy of a blow exceeds the absorbable energy.
  • the two levers are coupled within the dynamic range and can be pivoted around the axes in the transverse direction of the ski. This has the advantage that the movement of the two levers is guided by the axes.
  • the two levers are coupled within the dynamic range and can be moved along a linear path in the transverse direction of the ski.
  • This can, for example, be a translational movement of the two levers, in which the two levers are coupled and moved in the transverse direction of the ski.
  • the movement of the two levers along the linear path can, for example, also be a combination of a translational movement and a pivoting movement of the two levers, in which the two levers are coupled and moved in the transverse direction of the ski and pivoted about the axes.
  • the dynamic path of the holding means can be designed in such a way that forces acting from different directions on a ski boot held in the front automatic device can be optimally absorbed by the front automatic device.
  • the front automaton for a ski binding comprises two levers arranged laterally opposite one another as seen in the longitudinal direction of the ski, each with a holding means for holding a ski boot in a toe area of the ski boot.
  • the two levers are preferably each mounted so as to be pivotable about an axis and the holding means are moved by the levers during a pivoting movement in a transverse direction of the ski, the front automaton preferably comprising an element referred to as a positive control and the two levers being mountable on this positive control and on another element of the front automaton.

  • preferred embodiments of the front-loading machine can also be designed differently.
  • the following shows how such other preferred embodiments can be designed using advantageous features.
  • the two preferred embodiments mentioned above can also include one or more of these advantageous features.
  • the axes of the levers are advantageously arranged in a plane parallel to the skis. This has the advantage that the axes can be arranged below the holding means, thereby achieving a compact design of the front automatic device.
  • the axes are also preferably aligned essentially parallel to the skis, although deviations from a parallel alignment of 10 degrees or 20 degrees can be provided. Preferably, however, the lateral deviation of the axes from a parallel alignment is less than 10 degrees. If the levers can be pivoted within the dynamic range and the dynamic path of the holding means lies in a plane perpendicular to the axis of the respective lever, one plane of the dynamic paths of the holding means is aligned essentially in the transverse direction of the skis.
  • the two levers are coupled within the dynamic range and can be moved in the transverse direction of the skis along a linear path
  • the alignment of the axes can result in a continuation of the movement of the holding means in the transverse direction of the skis when the levers are pivoted about the axes.
  • this arrangement of the axes is advantageous if the front automatic device provides a lateral safety release. With such a lateral safety release, the ski boot moves essentially in a plane parallel to the ski boot.
  • the movement of the ski boot can include both a linear movement and a rotation about a vertical axis of the ski boot.
  • the dynamic path of the holding means can best absorb movements of the ski boot caused by differently oriented forces running across the ski. Accordingly, the energy that the front automatic device can absorb can be specified as best as possible for different forces. By specifying the absorbable energy, a controlled, lateral safety release can be enabled, which occurs when the absorbable energy is exceeded.
  • the axes can be aligned differently. For example, they can be aligned vertically or at any angle to the longitudinal direction of the ski.
  • both levers comprise a control bar for interacting with a ski boot on a side facing the middle of the ski.
  • These control bars can, for example, be an element attached to the corresponding lever and protruding towards the middle of the ski.
  • the control bars have the advantage that when the two levers are pivoted above a certain pivot angle, the control bar of the lever in the direction of movement can interact with the ski boot and the holding means of this lever can therefore be released from the ski boot.
  • This has the advantage that the process of a lateral safety release from the front automatic device can be simplified. This means that if the front automatic device provides a lateral safety release, the movement sequence of the ski boot becomes more continuous when the safety is released from the side and this increases safety for the skier.
  • the control bars can interact with the ski boot when the levers are pivoted within the dynamic range. If, however, the two levers are movable along a linear path within the dynamic range and, for example, at least one of the two levers can pivot about the corresponding axis in the event of a lateral safety release, the corresponding control arm can interact with the ski boot in the event of the safety release, whereby the ski boot can be released more easily from the front automatic device.

  • the levers comprise a control arm-like arch, which is also included under the term control arm.
  • the two levers may not comprise a control bar arranged on the side of the levers facing the middle of the ski. If, for example, the holding means are designed in such a way that they easily detach from the ski boot when the levers are pivoted beyond a certain angle, this alternative may be advantageous since it simplifies the design of the front automatic device and makes its manufacture more cost-effective.

  • the two levers in the holding position are preferably fixedly mounted on the forced control, whereby the two levers are coupled and movable within the dynamic range.
  • the forced control in the holding position is preferably movable with a coupled pivoting movement of the two levers within the dynamic range of the two levers along a forced control path. How exactly the forced control is moved in these two cases is not specified.
  • its movement can be a movement in a linear direction, a pivoting or rotating movement, or a combination thereof.

All such movements of the forced control along the forced control path have the advantage that a coupled Pivoting movement of the two levers along the dynamic range can be achieved.
  • the movement of the forced control is a movement in a linear direction, a swivel movement or a combination of these, the movement and thus also the forced control path are preferably aligned in the cross-ski direction. This has the advantage that the forced control can follow the coupled swivel movement of the two levers, which simplifies the design of the front automatic device.
  • the forced control it is also possible for the forced control to not be movable in the holding position, but to be fixed to the ski.
  • the positive control is movable in the holding position, then if it deviates from a center of the positive control path, it can preferably be pressed with a force towards the center of the positive control path by a pre-tensioned, elastic element. It is also possible for more than one pre-tensioned, elastic element to be present. Regardless of the number of elastic elements, this has the advantage that the positive control is moved by the elastic element(s) to the center of the positive control path when no other force acts on the positive control. The two levers can also be moved to a center of the dynamic range using the positive control.
  • the two levers can be moved from this center of the dynamic range in both a first and a second direction along the dynamic range under the influence of a lateral force, and are moved back to the center of the dynamic range when the lateral force is removed. If a sideways impact or sideways force occurs on the ski boot or ski during ski skating, the corresponding energy can be absorbed by the front automatic system without the ski boot coming loose, regardless of which side the impact or force comes from.
  • the mentioned center of the forced control path and the mentioned center of the dynamic range can be the geometric center of the forced control path or the dynamic area. However, it can also be a point in the forced control path or dynamic area that is not in the geometric center. It is possible for these centers to be in a continuous area of the forced control path or dynamic area. In this case, the centers are given by the fact that the forced control or the levers are pressed to this point in the forced control path or dynamic area by the elastic element(s). However, it is also possible for the centers to be in a bend in the forced control path or dynamic area.
  • the forced control path can be v-shaped and the center of the forced control path can be in the tip of the "v".
  • the forced control can be moved from the center of the forced control path along one or the other arm of the "v" depending on the direction of the lateral force or lateral impact.
  • the center of the forced control path can also be at one end of the forced control path. This can be the case in particular if the forced control path runs along the longitudinal direction of the ski. Then the forced control can be moved in the longitudinal direction of the ski starting from this end of the forced control path, but in this example the two levers are mounted on the forced control in the holding position in such a way that they can be pivoted in the direction of action of the lateral force or lateral impact, while the forced control is moved in the longitudinal direction of the ski independently of the direction of action of the lateral force.

  • the two pivot levers 5.1, 5.2 are pivoted to the end of the dynamic range, whereby the pivot lever 5.1, which is in the pivoting direction, is released by the forced control 20 and tilted downwards.
  • the control plate 20.3 has a laterally flattened recess 25. Since the control plate 20.3 in the Figures 8b and 8c is moved sideways from its central position, the piston 35 is pressed backwards from the corresponding flank of the recess 25 in the control plate 20.3 out of the recess 25 against the preload of the spiral spring 36. Due to the flank of the recess 25 being aligned at an angle to the spring force, a restoring force is exerted on the control plate 20.3, which drives the control plate 20.3 back to its central position.
  • This restoring force and the path that a ski boot stored in the front automatic device 1 travels from its central position to the end of the dynamic path provide a maximum energy, which the front automatic device 1 can absorb without a lateral safety release occurring.
  • This maximum energy can be set by pre-tensioning the spiral spring 36 by means of the adjusting screw 38 and the locking nut 37.
  • the side safety release which is in the Figures 7a, 7b, 7c , as well as 8a, 8b and 8c, can also be done on the other side, not shown here.

  • the ski boot 100 is shown tilted forwards, with a toe area 102 of the ski boot 100 touching the control lever 3. If a skier who uses a front automatic device 1 falls forwards, the ski boot 100 can be pushed further than in the Figure 9 shown.
  • the front automatic device 1 can be used in a touring binding system together with a heel automatic device (not shown).
  • the heel automatic device should enable storage of the ski boot 100 in a heel area.
  • a downhill position in which the front automatic device 1 is in the holding position and in which the ski boot 100 is stored in its toe area in the front automatic device 1 and in its heel area on the heel automatic device.
  • a touring binding system enables an ascent position in which the ski boot 100 is stored in the front automatic device 1 and released by the heel automatic device. In this ascent position, the front automatic device 1 can be in the holding position or in the blocking position. In both positions, it enables a pivoting movement of the ski boot 100 about a transverse axis of the ski and accordingly enables a walking movement of a skier.
  • the front automatic mechanism 1 enables a lateral safety release in the holding position. If a ski boot 100 is stored in a touring binding system with the front automatic mechanism 1 and the touring binding system is in the downhill position, the touring binding system enables a lateral safety release. If, for example, the ski boot 100 is stored on the heel automatic mechanism by holding spurs pointing from back to front, the ski boot 100 can perform a rotary movement in the event of such a lateral safety release. It is first released laterally from the front automatic mechanism 1 while it is still held by the holding spurs of the heel automatic mechanism. As soon as the ski boot 100 is released from the front automatic mechanism 1, it can also be released from the heel automatic mechanism by moving or rotating it away from the holding spurs of the heel automatic mechanism. Accordingly, a lateral safety release option via the heel automatic mechanism is no longer necessary. It is sufficient if the heel unit enables a safety release in the forward direction.
  • the front automat 1 is optimized for a lateral safety release in a touring binding system where the heel automat does not allow a lateral safety release.
  • This optimization is in the Figure 10 which shows a view of the front machine 1 in the holding position with the safety shoe 100 held therein, illustrated.
  • Two dashed lines are shown along which the axes 9.1, 9.2 (see Figure 3 ), around which the two pivot levers 5.1, 5.2 can be pivoted.
  • These two straight lines 15.1, 15.2 run backwards at an angle of 6 degrees to the longitudinal axis of the ski and intersect at a point 16 in the heel area of the ski boot 100.
  • the ski boot 100 Since the heel mechanism does not allow a lateral safety release, the ski boot 100 is rotated about a vertical axis near point 16 in the event of a lateral safety release until it is released from the front mechanism 1. As a result, the pivoting movement of the pivot lever 5.1, 5.2 located in the direction of movement runs perpendicular to the direction of movement of the ski boot 100. Accordingly, the alignment of the axes 9.1, 9.2 is optimized for a rotary movement of the ski boot 100 in the event of a lateral safety release.

  • the front machine 1 which is in the Figures 11a, 11b and 11c has two differences compared to the previously shown front automaton 1. These differences illustrate further design options for the front automaton 1.
  • the first difference is that the piston 35 is guided by a knob in a cut in the guide element 50 aligned in the longitudinal direction of the ski (see Figure 11c ). Since the I ⁇ bolben 35 is guided at the top and bottom in the longitudinal direction of the ski, the I ⁇ bolben 35 is guided better in the longitudinal direction of the ski, so that a better Power transmission from the piston 35 to the control plate 20.3 is achieved, thereby minimising friction losses.
  • the second difference is that the laterally flattened recess 25 has a recess 42.1, 42.2 on each side, into which the steel disk 40 of the piston 35 can engage when the front automat 1 is in the safety release position (see Figures 11a and 11b b).
  • the restoring force acting on the control plate 20.3 can be minimized or completely eliminated in the safety release position. Accordingly, the pivoting of the corresponding pivot lever 5.1 is made easier, since the minimized or eliminated restoring force also minimizes or eliminates the frictional resistance for the pivoting movement of the pivot lever 5.1.
  • FIGS. 12a, 12b and 12c show a similar view of the front machine 1 as the Figures 11a, 11b and 11c , whereby the Figures 12a, 12b and 12c but illustrate another possible design.
  • the piston 35 does not have a steel disk 40 at its tip.
  • a pivoting element 43 is arranged between the piston 35 and the control plate 20.3.
  • This pivoting element 43 is pivotally mounted in its center about a vertically aligned pivot axis 44.
  • To the front it has a rounded, first foot 45.1, which engages in the laterally flattened recess 25 of the control plate 20.3.
  • the pivoting element On both sides of the center of the ski, the pivoting element also has a second and third foot 45.2, 45.3, each facing backwards, behind the pivot axis 44.
  • these two feet 45.2, 45.3 are supported backwards against the piston 35 (see Figure 12a ).
  • the first foot 45.1 of the swivel element 43 is moved along with it, whereby the swivel element 43 is swiveled about its axis 44 (see Figure 12b ).
  • the foot 45.2 of the swivel element which lies in the direction of movement of the positive control 20 presses the piston 35 backwards, while the other foot 45.3 no longer touches the piston 35.
  • the front automaton 1 is shown in the holding position from below, with the base plate 30 hidden, while the guide element 50 is shown.
  • the Figures 13a and 13b each show a vertical cross-section through the front machine 1, seen from the front, through the forced control 20.
  • the forced control 20 of the front machine 1 is located at one end of the forced control path.
  • the Figure 13a is the one in the Figures 11a, 11b and 11c shown execution option, while in the Figure 13b that in the Figures 12a, 12b and 12c shown.
  • Both differ from the previously described design options in that the curved sections of the first sliding guides 23.1, 23.2 become wider towards the bottom. This allows the first sliding blocks 24.1, 24.3 to move in the curved section of the first sliding guides 23.1, 23.2 with less frictional resistance. This makes it easier to move the corresponding pivot lever 5.1, 5.2 away in the safety release position.
  • the retaining spurs 6.1, 6.2 which are shown in the Figures 13a, 13b shown, have more rounded free ends. This means that the ski boot can be released more easily from the front automatic device 1 in the event of a lateral safety release. However, this slightly impairs the storage of the ski boot in the front automatic device 1. Accordingly, it is possible that the shape of the free ends of the retaining spurs 6.1, 6.2 in the front automatic device 1 is optimized between optimal storage of the ski boot and optimal release of the ski boot from the front automatic device 1. It should be mentioned that the retaining means can also be designed completely differently than the retaining spurs 6.1, 6.2 shown here.

This ensures that the cover 413.1, 413.2 of the sideways pivoting lever 405.1, 405.1 can be pivoted upwards in front of the sole of the ski boot in the event of a lateral safety release.
  • a second major difference between the front-loading machine 401 shown here and the one in the Figures 25 to 27c The advantage of the front machine 301 shown is that the front machine 401 comprises not only one but two base plates 430.1, 430.2 and a holding element 430.3. Of these three elements, a first base plate 430.1 as a guide for the movement of the carriage 420.4 in the transverse direction of the ski. In its front area in front of the guide for the carriage 420.4 it has two openings 431.1, 431.4 through which screws can be passed for fastening the front automatic device 401 to a SI ⁇ i. A second base plate 430.2 also has two openings 431.2, 431.3 in its front area through which screws can be passed for fastening the front automatic device 401 to a SI ⁇ i.
  • This second base plate 430.2 is arranged behind the first base plate 430.1 and serves as a base for the holding element 430.3, which also has two openings 433 for fastening to a SI ⁇ i.
  • This holding element 430.3 is formed from a piece of sheet metal. In a cross-section aligned vertically in the transverse direction of the ski, this holding element 430.3 has a substantially U-shape, with the two upper edges bent inwards. As a result, the holding element 430.3 forms a rail-like longitudinal guide for the housing 402 of the front automatic device 401, whereby the housing 402 of the front automatic device 401 cannot be moved upwards relative to the holding element 430.3.
  • the front automatic device 401 when the front automatic device 401 is mounted on an SI ⁇ i, four screws are guided through four vertically aligned openings 432.1, 432.2, 432.3, 432.4 arranged in the housing 402 and screwed tightly to the SI ⁇ i.
  • the two front screws run through the two front openings 432.1, 432.4 of the housing 402 as well as through the two openings 431.1, 431.4 of the first base plate 430.1 and hold the housing 402 and the first base plate 430.1 firmly on the ski.
  • the two rear screws are guided downwards through the rear openings 432.2, 432.3 of the housing 402 when fastening the front automatic device 401, where they run through the two openings in the holding element 430.3 and through the two openings 431.2, 431.3 of the second base plate 430.2 and only hold the holding element 430.3 and the second base plate 430.2 to the SI ⁇ i. Therefore, in the assembled state, when the front automaton 401 is attached to a SI ⁇ i, the housing 402 is only screwed to the SI ⁇ i by the two front screws.
  • the rear area of the housing 402 is held in the longitudinal guide of the holding element 430.3 screwed to the SI ⁇ i and can move in the longitudinal direction of the ski relative to the holding element 430.3.
  • a third major difference between the front-loading machine 401 shown here and the Figures 14a to 24c or 25 to 27c is that the front automaton 401 has a damping position instead of a blocking position. Accordingly, the control lever 403 of the front automaton 401 shown here does not comprise a latch with which a movement of the carriage 420.4 in the transverse direction of the ski can be blocked. On the other hand, the control lever 403 comprises two curvatures 428.1, 428.2 which press from the front against a front side of the carriage 420.4 when the control lever 403 is moved upwards into a damping position. As a result, a movement of the carriage 420.4 in the transverse direction of the ski is subjected to increased resistance to movement due to friction.
  • the carriage 420.4 can be moved less well in the transverse direction of the ski in the damping position of the front automaton 401. Therefore, if the damper position is used when climbing, the ski boot is prevented from swinging back and forth relative to the ski boot held in the front automatic device 401. Accordingly, the damper position increases the skier's sure-footedness. At the same time, however, a lateral safety release can still take place in the damper position, which ensures safety for the skier even in the damper position.
  • FIGS. 29a, 29b and 29c each show a bottom view of a horizontally aligned cross section through the front machine 401, which runs through the pivoting element 420.3 and through the horizontal slot 420.5 in the carriage 420.4.

  • the pivot element 420.3 is supported against a metal front side 437 of the piston 435.

  • the pivoting element 420.3 also comprises a head 441 arranged between its two arms 440.1, 440.2. This head 441 is arranged in front of the first vertical axis 448 and has a side that points forward and has a locking position.

This means that the outer ends of the two arms 440.1, 440.2, which are bent towards each other towards the middle of the ski, give the stops 412.1, 412.2 more space for movement towards the middle of the ski compared to the holding position.
  • the two pivot levers 405.1, 405.2 are each connected by a leg spring 429.1 429.2 with a This force causes the pivot levers 405.1, 405.2 to be pivoted as far apart as possible in the release position and the two stops 412.1, 412.2 strike the outer ends of the two arms 440.1, 440.2. This ensures that the two retaining spurs are at the first distance from each other.
  • the control lever 403 does not press against the head 441 of the swivel element 420.3. Accordingly, the swivel element 420.3 is moved forward in the holding position by the spiral spring 436 and the piston 435 as far as the bearing of the first vertical axis 448 in the slide 420.4 allows. In this position, the head 441 of the swivel element 420.3 is located just inside the front side of the slide 420.4.
  • the two arms 440.1, 440.2 of the pivoting element 420.3 are also located so far forward in the slide 420.4 that the stops 412.1, 412.2 of the two pivoting levers 405.1, 405.2 in the rear area of the outer ends of the arms 440.1, 440.2 abut against the outer ends of the arms 440.1, 440.2. Since the outer ends of the two arms 440.1, 440.2 are furthest apart from each other in their rear area, the stops 412.1, 412.2 are also moved further apart compared to the release position. This means that the pivoting levers 405.1, 405.2 are pivoted together so that the two retaining spurs are at the second distance from each other.
  • the front machine 401 is in the Figure 29c in the safety release position with a swivel lever 405.1 swung away to the side.
  • the forced control 420 is moved to one end of the forced control path, whereby the swivel element 420.3 is swung about the first vertical axis 448 and about the second vertical axis 449 to the side of the swivel lever 405.1 released by the safety release. Due to this swivel movement, the arm 440.1 of the swivel element 420.3, against which the swiveled-away swivel lever 405.1 is supported in the holding position by its stop 412.1, is moved backwards.
  • the stop 412.1 of the swiveled-away swivel lever is located 405.1 in front of the arm 440.1 of the pivoting element 405.1, viewed in the longitudinal direction of the ski. Since the pivoting lever 405.1 is thus released from the pivoting element 420.3, it is pivoted outwards by the leg spring 429.1 with the retaining spur, while its stop 412.1 is moved towards the middle of the ski. Because the stop 412.1 is therefore in front of the arm 440.1 of the pivoting element 420.3, the stop 412.1 prevents the arm 440.1 of the pivoting element 420.3 from being moved forward again. Accordingly, a movement of the forced control 420 back to the middle of the forced control path is blocked.
  • this pivot lever 405.2 is not pivoted outwards with the retaining spur because the movement of the carriage 420.4 in the transverse direction of the ski moves the cover 413.2 of the corresponding pivot lever 405.2 below a central region of the housing 402 and abuts against the bottom of the housing 402.
  • the pivot levers 405.1, 405.2 can be pivoted against the spring force of the leg springs 429.1, 429.2 with the holding spurs towards the middle of the ski. If a ski with the front automatic device 401 falls over and hits a pivot lever 405.1, 405.2, the corresponding pivot lever 405.1, 405.2 can be pivoted inwards towards the middle of the ski, which reduces the risk of damage to the front automatic device 401.

As a result, a locking unit 408 arranged below the ski transverse axis 407 on the control lever 403 and running concentrically about the ski transverse axis is moved backwards and presses the head 441 of the swivel element 420.3 backwards. A rear end of the locking unit 408 is locked in the locking position on the head 441 of the swivel element 420.3.

As soon as the locking unit 408 is released from the locking position, the locking unit 408 is moved forwards by the spiral spring 436 together with the swivel element 420.3 and the piston 435.
