Description

Technical area

The invention relates to a front automatic for a ski binding, in particular a touring ski binding. This front-mounted machine comprises two levers which are arranged laterally in the longitudinal direction of the ski and each have a holding means for holding a ski boot in a toe region of the ski boot. The two levers are each mounted such pivotable about an axis that the holding means are moved in a pivotal movement of the lever about these axes in a Skiquerrichtung. The front automatic machine has a release position, in which the two holding means are at a first distance from each other. In addition, it has a holding position, in which the two holding means are at a second distance from each other, which is smaller than the first distance.

State of the art

With regard to their function ski bindings are subdivided into piste bindings, which are used only for skiing and downhill at ski lifts, and touring bindings, which are also used for walking on skis, especially for ascending with the help of attached to the skis climbing skins. While the former only have to ensure a reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must be brought to ascend additionally from the downhill to a climbing position in which the ski boot is pivotable about an axis in Skiquerrichtung pivotally in the heel area of the ski to allow for joint movement between the ski boot and the ski to go.

Touring ski bindings, in turn, are subdivided into two types. One type comprises a ski boot carrier which can be pivoted relative to the ski and to which the ski boot is held by binding jaws. A representative member of this type of touring ski bindings is described for example in EP 0 754 079 B1 (Fritschi AG). The second type of touring ski bindings does not include such a ski boot carrier. In this type, the ski boot is pivotally mounted in a toe area on the sole in a ski-mounted front automat. In this case, the automatic heel unit is also fixedly mounted in a distance from the front automaton on the ski adapted to a ski boot sole length and locks the shoe in the heel area in the downhill position. In the ascent position, the heel of the heel is released from the heel counter, so that the heel of the heel can be lifted off the ski and swiveled around the bearing on the front automat. For this type of binding suitable ski boots this typically have in the toe area two lateral recesses for pivotal mounting in the front vending machine. In the heel area, recesses which are open at the rear are formed on the shoe sole into which holding means of the heel unit can engage. In addition, such ski boots on a stiff or only slightly bendable sole. In the latter case, the ski boots can be formed bendable, for example, in the ball area of the foot.

For the description of such binding systems, a (fictitious) ski is often used as the reference system, it being assumed that the binding is mounted on this ski. This habit is taken over in the present text. Thus, the term "ski longitudinal direction" means along the orientation of the longitudinal axis of the ski. Similarly, "skiparallel" means an elongated object aligned along the longitudinal axis of the ski. For a flat object, however, the term "ski-parallel" means aligned parallel to the sliding surface of the ski. Further, the term "ski direction" means a direction transverse to the ski longitudinal direction, which, however, need not be oriented exactly at right angles to the longitudinal axis of the ski. Their orientation may also be slightly different from a right angle. The term "ski center", on the other hand, means a center of the ski in the ski direction, while the term "ski lift" does not mean that it can move in relation to the ski. It should also be noted that terms that do not contain the word "ski" refer to the reference system of the (fictitious) ski. Thus, the terms "front", "rear", "top", "bottom" and "lateral" refer to "front", "rear", "top", "bottom" and "side" of the ski. Likewise, terms such as "horizontal" and "vertical" refer to the ski, with "horizontal" lying in a plane parallel to the ski and "vertical" oriented perpendicular to this plane.

A touring ski binding of the second type introduced above is described in EP 0 199 098 A2 (Bartel) and sold under the name Dynafit. The binding front part of this system comprises two angle levers, which are arranged opposite each other in the cross-machine direction and each are pivotally mounted about an axis extending in the longitudinal direction of the ski. The two angle levers each have an upwardly directed and a sideways aligned arm, which are arranged at right angles to each other. The upwardly oriented arms each comprise a truncated conical or hemispherical pin pointing towards the center of the ski, which can engage in recesses provided in the toe area of a ski boot. The laterally oriented arms of the angle lever point like the pin towards the center of the ski, but are in operative connection with each other via a spring device. Since the two angle levers are spring-loaded by the spring means via the laterally oriented arms, they can snap upwards and upwards by overcoming a dead center position in which the two laterally directed arms are aligned in linear extension to one another. When the sideward arms are snapped down, the upwardly directed arms are pivoted together. On the other hand, when the sideways-aligned arms are snapped upwards, the upwardly directed arms are swung apart. Accordingly, the pins for holding a ski boot in the first case are closer to each other and in the second case further apart. In the first case can be held by the pins a ski boot between the two angle levers, or pivotally mounted. Therefore, this position of the binding front part is a holding position. In the second case, however, the holding means are sufficiently far apart so that the ski boot is released. Accordingly, this position of the binding front part is a release position.

In order to bring the binding front part from the holding position to the release position and back, the binding front part described in EP 0 199 098 A2 (Bartel) comprises an opening lever which is pivotable about an axis oriented in the direction of the ski and which connects the two laterally aligned arms of the angle lever top and bottom embraces. By actuating this opening lever, the laterally oriented arms of the angle levers can be pushed upwards, where they snap into the free-standing position. By reverse operation of the opening lever, the laterally aligned arms of the angle lever can also be pressed down, where they snap into the holding position.

In a fall of the ski boot can be solved without actuation of the opening lever from the ski binding system. For this purpose, the ski boot is first released from the heel counter and then from the binding front part. If it is a frontal fall, the ski boot is released from the heel unit up and tilted forward in the binding front. If the forward or upward force on the ski boot is sufficiently large, the ski boot is also torn out of the binding front part by overcoming the force acting on the two angle levers. If, on the other hand, it is a lateral fall, the ski boot is released laterally by the heel counter and turned about a vertical axis lying in the toe area of the ski boot. In this case, the ski boot is rotationally released from the binding front part, by overcoming the force acting on the angle lever force.

Because of this possible solution of the binding front part, there is the problem that can inadvertently detach from the binding front part in the ascent position of the ski boot by a lateral torque and thus completely detached from the ski. Such unintentional release can be prevented according to EP 0 199 098 A2 (Bartel) by blocking the opening lever and thus the two angle levers.

A further development of the binding front part according to EP 0 199 098 A2 (Bartel) is described in WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.). Here grab the sideways aligned arms of the angle lever not in the release position, but are always biased to the holding position. As a result, the angle levers are not moved over a dead center. Accordingly, they must be held in the free position by a stopper, so they do not snap into the holding position.

Both the binding front part according to EP 0 199 098 A2 (Bartel) and the binding front part according to WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.) have the disadvantage that tripping occurs uncontrollably. When triggered, the two angle levers are pressed apart by an acting on the ski force (or torque) in an undefined manner, whereby the ski boot is released from the binding front part.

A somewhat different approach is followed in the front-end automata, which is described in WO 2007/010 392 A2 (Ski Trab S.R.L). Although this front automaton also comprises two angle levers, each comprising two arms arranged substantially at right angles to each other. First arms of this angle lever also each include a center of the ski facing, truncated cone or hemispherical pin designed to hold a ski boot. In addition, second arms of this angle lever are also aligned laterally to the ski center pointing each other. In contrast to the front automata described above, however, the two angle levers are pivotally mounted about vertical axes, wherein the axes are arranged in front of the toe area of the ski boot. In addition, the second arms of the angle lever are not in direct operative connection, but each engage with their end in a lateral recess of a pivot lever aligned in the longitudinal direction of the ski. This pivot lever is displaceable in the longitudinal direction of the ski, wherein the ends of the second arms of the two angle levers are carried in the side incisions. Accordingly, the two angle levers are pivoted to each other or apart during a displacement of the pivot lever, whereby a transfer of the front vending machine is achieved by the release position in the holding position and back.

In addition to the displaceability in the ski longitudinal direction of the pivot lever is pivotally mounted about a vertical axis on the front vending machine, but it is pressed by two springs in a ski-parallel alignment. In a force acting laterally on the ski boot, therefore, the outer of the two angle levers can be pushed outwards by the pivot lever is pivoted slightly laterally against the spring force, until the angle lever is released from the lateral incision in the pivot lever. At the same time the inner angle lever is pivoted by the pivoting movement of the pivot lever following the outer angle lever slightly inward. As a result, the front automatic according to WO 2007/010 392 A2 (Ski Trab S.R.L.) allows a lateral release, in which the storage of the ski boot is only loosened, and as soon as the outer angle lever is released, is completely released. Furthermore, the front-end automatic allows a frontal release, which, however, is just as uncontrolled as in the binding front parts according to EP 0 199 098 A2 (Bartel) and WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.).

Even with the front-mounted vending machine according to WO 2007/010 392 A2 (Ski Trab S.R.L.) There is the problem that in the ascent position of the ski boot due to a lateral force can inadvertently detach from the front vending machine and thereby completely released from the ski. According to WO 2007/010 392 A2 (Ski Trab S.R.L.) Such unintentional release can be prevented by the pivot lever and thus the two angle levers are blocked.

The disadvantage of these known binding front parts and front automata is that they offer only limited security for the skier. As already mentioned, the two binding front parts according to EP 0 199 098 A2 (Bartel) and WO 2009/121 187 A1 (G3 Genuine Guide Gear Inc.) offer neither a frontal nor a lateral direction a defined safety release. The automatic front-end according to WO 2007/010 392 A2 (Ski Trab S.R.L.) does offer a lateral safety release within a limited scope. However, it is due to the interaction of the two angle lever with the pivot lever to a continuous spreading and thus opening the two angle lever until the outer bell crank is fully released and swung away. The ski boot is already at least partially solved during the spreading of the angle lever. In addition, the front automatic according to WO 2007/010 392 A2 (Ski Trab S.R.L.) offers no frontal release. It only allows the ski boot to be torn out of the front automat by applying sufficient force to the front or the top. Therefore, these known front automata provide little security for a skier.

Presentation of the invention

The object of the invention is to provide a the aforementioned technical field associated with front automata, which increases the safety of a skier.

The solution of the problem is defined by the features of claim 1. According to the invention, the front automatic transmission comprises a positive control, on which the two levers are mounted in the arresting position, so that the two levers can be moved coupled in a skiquer direction within a dynamic range and the two retaining means are coupled at a second distance to each other on a dynamic path in the transverse direction become. For example, the coupled movement of the two levers along the dynamic range may be pivotal movement of the two levers about the axes. The coupled movement of the two levers along the dynamic range may, for example, also be a linear movement along a linear path, which corresponds to a translatory movement of the two levers, in which the two levers are displaced in a coupled manner in the transverse direction. The coupled movement of the two levers along the dynamic range may, for example, also be a linear movement along a linear path, which corresponds to a combination of a translational movement and a pivotal movement of the two levers, in which the two levers are coupled in the transverse direction and coupled to be pivoted about the axes.

The dynamic range may be limited on one or both sides by a stop by which at least one of the two levers is stopped and prevented in its further freedom of movement. However, there is also the possibility that the dynamic range on one or both sides is limited by the fact that the two levers are no longer coupled from a certain position, but can be moved decoupled. Of course, there is also the possibility that the dynamic range for one of the levers is limited by a stop and for the other, the lever is limited by the fact that it is decoupled from a certain position. The type of limitation for the two levers can also be dependent on the side of the dynamic range. This means that, for example, the dynamic range on a first side for a first of the two levers is limited by a stop and is limited for a second of the two levers in that it can be decoupled from a certain position. At the same time, the dynamic range on a second side for the first lever may be limited by being decoupled from a certain position, while the dynamic range on the second side is limited by a stop for the second lever.

The solution has the advantage that a ski boot held in the front automate can be moved together with the two holding means in the holding position on the dynamic path in Skiquerrichtung. This movement can be absorbed by the front automate energy without the ski boot is released from the front vending machine. This is advantageous when skiing and possibly in a fall, since blows to the ski or the ski boot may arise in which the ski boot should not detach from the front automat. In order to set a strength of the bearable strokes, the energy that can be absorbed by the front automat can be predetermined by adjusting the length of the dynamic path and / or a resistance force which has to be applied for the movement. Accordingly, a controlled safety release can be provided, which is triggered when the energy of a shock should exceed the recordable energy.

In a first, preferred variant, the two levers are coupled within the dynamic range coupled in Skiquerrichtung about the axes in the locking position. This has the advantage that the movement of the two levers is guided by the axes.

In a second, preferred variant, the two levers are coupled within the dynamic range coupled in a direction along a linear path Skiquerrichtung. This may be, for example, a translational movement of the two levers, in which the two levers are moved in a coupled manner in the transverse direction. This has the advantage that in the holding position, a stable connection between the two levers can be specified, which keeps the two holding means on the levers in the second distance to each other. The movement of the two levers along the linear path may, for example, also be a combination of a translational movement and a pivotal movement of the two levers, in which the two levers are coupled in the transverse direction and pivoted about the axes. This has the advantage that a course of the dynamic path of the holding means can be designed such that forces which act from different directions on a ski boot held in the front automatic machine can be optimally absorbed by the front automatic machine.

In a preferred embodiment, the front automatic for a ski binding, in particular a touring ski binding, seen in the longitudinal direction of the ski laterally arranged, opposite lever each having a holding means for holding a ski boot in a toe area of the ski boot. In this case, the two levers are preferably each pivotally mounted about an axis and the holding means are moved by the levers in a pivoting movement in a Skiquerrichtung, the front automaton preferably comprises a designated as a positive control element and the two levers on this positive control and on another element of the Front automats are storable. The front automatic machine preferably has a release position in which the two holding means are at a first distance from one another.

Further, the front automatic machine preferably has a holding position, in which the two holding means are at a second distance from each other, which is smaller than the first distance. Advantageously, the two levers are movably mounted on the positive control in the holding position, which is also movable in the holding position. Here, the two levers are preferably coupled by the movable positive control within a dynamic range coupled in Skiquerrichtung, the two holding means are coupled coupled at a second distance to each other on a dynamic path in Skiquerrichtung be moved. How the forced control is moved is not specified. It may, for example, be a linear movement or a pivoting or rotating movement.

In a further preferred embodiment, the front automatic for a ski binding, in particular a touring ski binding, seen in the longitudinal direction of the ski laterally arranged, opposite lever each having a holding means for holding a ski boot in a toe area of the ski boot. The two levers are preferably each pivotally mounted about an axis and the holding means are moved by the levers in a pivoting movement in a Skiquerrichtung, the front automaton preferably comprises a designated as a positive control element and the axes are mounted on this positive control. The front automatic machine preferably has a release position in which the two holding means are at a first distance from one another. Furthermore, the front automatic machine preferably has a holding position in which the two holding means are at a second distance from each other, which is smaller than the first distance. Advantageously, the two levers are mounted on the positive control, which is movable in the holding position. In this case, the two levers are preferably movable in the transverse direction, coupled by the movable positive control within a dynamic range, wherein the two holding means are coupled and moved at a second distance from each other on a dynamic path in the transverse direction. How the forced control is moved is not specified. It may, for example, be a linear movement or a pivoting or rotating movement.

However, preferred embodiments of the front automatic machine 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 two above-mentioned, preferred embodiments may include one or more of these advantageous features.

Advantageously, the axes of the levers are arranged in a plane parallel to the ski. This has the advantage that the axes can be arranged below the holding means, whereby a compact design of the front automatic is achieved. In addition, the axes are preferably oriented essentially in the same direction as a ski, although deviations from a parallel alignment of 10 degrees or 20 degrees may be provided. Preferably, however, the lateral deviation of the axes from a ski-parallel alignment is less than 10 degrees. If the levers are pivotable within the dynamic range and, accordingly, the dynamic path of the holding means lies in a plane perpendicular to the axis of the respective lever, thereby aligning a plane of the dynamic paths of the holding means substantially in the cross-machine direction. This is advantageous in the event that the front panel provides a lateral safety release. In such a lateral safety release, a movement of the ski boot essentially runs in a plane parallel to the ski. The movement of the ski boot may include both a linear movement and a rotation about a vertical axis of the ski boot. Since the plane of the dynamic path is thus oriented essentially perpendicular to the plane of movement of the ski boot, the dynamic path of the holding means can best accommodate movements of the ski boot, which are caused by differently oriented, in Skiquerrichtung forces. Correspondingly, the energy that can be absorbed by the front-end automaton can be predefined in the best possible manner for different forces. By specifying the absorbable energy, in turn, a controlled, lateral safety release can be made possible, which occurs when the absorbable energy is exceeded.

Alternatively, there is also the possibility that the axes are aligned differently. For example, they can also be aligned vertically or at any angle to the ski longitudinal direction.

Advantageously, both levers each comprise a control jaw for interacting with a ski boot on one side of the ski center. These control jaws may, for example, each be an attached to the corresponding lever, rounded and projecting to the ski center element. The control jaws have the advantage that at a pivoting movement of the two levers from a certain pivot angle, the control jaw lying in the direction of movement lever can interact with the ski boot and thereby the holding means of this lever can be released from the ski boot. Accordingly, this has the advantage that the process of a lateral safety release from the front automate can be simplified. This means that if the front of the vehicle is equipped with a lateral safety release, the movement of the ski boot becomes more continuous in the event of a lateral safety release, thus increasing the safety for the skier. If the levers are pivotable about the axes within the dynamic range, the control jaws can already interact with the ski boot in the event of a pivotal movement of the levers within the dynamic range.

As a variant, there is also the possibility that the control jaws are not formed as a separate element. You can, for example, each be made in one piece with the corresponding lever, or the levers can also be shaped so that, for example, an arc in the lever takes over the function of a control jaw. In this last variant, the levers include a sterberbackigartigen bow, which is also under the term Steuerbacke.

Alternatively, the two levers but also not on the side directed to the ski center side of the lever arranged Steuerbacke include. For example, if the holding means are designed to be easily detached from the ski boot when the levers are pivoted beyond a certain angle, this alternative may be advantageous since this simplifies the construction of the front automat and makes its manufacture more cost effective.

If the two levers are pivotable about the axes within the dynamic range, the positive control in the retaining position is preferably movable in a coupled pivotal movement of the two levers within the dynamic range of the two levers along a positive control path. How the positive control is moved exactly is not predetermined. It may, for example, be a movement in a linear direction, a pivotal or rotational movement, or a combination thereof. Accordingly, the positive control path may be a rotation angle if the movement of the positive control is a rotary or pivoting movement. All such movements of the positive control along the positive control path have the advantage that in the holding position in a simple manner, a coupled pivotal movement of the two levers along the dynamic range can be achieved.

If the movement of the positive control is a movement in a linear direction, a pivotal movement or a combination thereof, the movement and thus also the positive control travel are preferably aligned in the cross-machine direction. This has the advantage that the positive control can join the coupled pivoting movement of the two levers, whereby the construction of the front automatic is simplified.

If the two levers, however, are movable within the dynamic range along a linear path, the positive control in the holding position is preferably movable along a positive control travel and the two levers in the holding position are preferably fixedly mounted on the positive control, whereby the two levers coupled within the dynamic range are movable.

As an alternative, however, there is also the possibility that the positive control is not movable in the holding position, but is arranged skifest.

If the positive control is movable in the holding position, so it is preferably pressed by a biased elastic element with a force to the center of the positive control travel at a deviation from a center of the positive control travel. There is also the possibility that more than one prestressed, elastic element is present. Regardless of the number of elastic elements, this has the advantage that the constraint control is moved by the one or more elastic members to the center of the positive control travel when no other force is applied to the positive control. It can be moved with the positive control and the two levers in a center of the dynamic range. Accordingly, the two levers can be moved along the dynamic range in both first and second directions under the influence of an incipient lateral force starting from this center of the dynamic range, moving back to the center of the dynamic range when the lateral force ceases become. Thus, if skiing results in a sideways impact or a lateral force on the ski boot or ski, the corresponding energy can be absorbed by the front automat without disengaging the ski boot, regardless of which side the impact or force comes from.

The mentioned center of the positive control travel and the mentioned center of the dynamic range may be the geometric center of the positive control travel or the dynamic range. However, it can also be a position in the positive control path or dynamic range, which does not lie in the geometric center. There is a possibility that these centers are in a continuous range of the constraint path or dynamic range. In this case, the centers are given by the fact that the positive control or the lever are pressed by the one or more elastic elements to this point in the positive control path or in the dynamic range. But there is also the possibility that the centers are in a kink in the positive control path or dynamic range. For example, the positive control path may be V-shaped and the center of the positive control path may be in the top of the "v". In this case, the positive control may be moved from the center of the positive control path, depending on the direction of the lateral force or the lateral impact along one or the other arm of the "v". For example, however, the center of the force control path may also be at one end of the force control path. This may be the case in particular when the positive control path runs along the ski longitudinal direction. The positive control can then be movable in the longitudinal direction of the ski starting from this end of the positive control travel, but in this example the two levers are mounted in the holding position on the positive control such that they are pivotable in the effective direction of the lateral force or the lateral impact, while the positive control is moved independently of the effective direction of the lateral force in the ski longitudinal direction.

As a variant, it is also possible that not the positive control, but one or both levers can be pressed by one or more biased elastic elements in the middle of the dynamic range. In the same way, however, both levers can each be pressed into the middle of the dynamic range separately by one or more prestressed elastic elements. In both cases, a corresponding embodiment may be particularly advantageous if the positive control itself is arranged skifest.

In all these variants with the biased or elastic elements, the prestressed, elastic element is preferably aligned in the ski center in the ski longitudinal direction. In a first preferred variant thereof, the prestressed, elastic element in the longitudinal direction of the ski presses on the positive control by pressing a laterally guided and thus laterally non-displaceable piston into a horizontally arranged, substantially V-shaped indentation in the positive control. In this case, the movable in the Skiquerrichtung positive control can be maintained in the middle of the positive control travel by the piston is pressed into a tip of the v-shaped indentation. Accordingly, the positive control can be moved from the center of the positive control travel along the positive control travel, wherein the piston is pressed by the corresponding edge of the substantially v-shaped recess in the longitudinal direction of the ski against the biased force of the elastic member. The force acting on the flanks of the substantially V-shaped indentations, directed in the longitudinal direction of the ski force of the elastic element causes a restoring force, which drives the positive control respectively back into the middle of the positive control travel. In order to minimize the frictional resistance between the positive control and the piston, for example, the piston may have at its tip a roller bearing which can roll on the flanks of the substantially V-shaped indentation in the positive control. But there is also the possibility that the piston has no roller bearing, but that the piston and / or the substantially V-shaped indentation in the positive control have a special coating which reduces the frictional resistance. There is also the possibility that the piston has at its tip a roller bearing which can roll on a special coating of the substantially V-shaped indentation in the positive control. But there is also the possibility that the piston does not include such a roller bearing and that neither the piston nor the substantially V-shaped indentation in the positive control have a special coating.

If a prestressed, elastic element is present and aligned in the ski center in the ski longitudinal direction, then presses in a second preferred variant, the biased elastic element in the longitudinal direction of the positive control by a laterally guided and thus laterally non-displaceable piston against a laterally guided and thus laterally non-displaceable pivoting element presses, so that a first foot of the pivoting element is pressed into a substantially V-shaped recess in the positive control. In this case, the pivoting element may for example comprise a second and third foot, which are each arranged on one side of the ski center on the pivoting element and aligned towards the piston. Thus, the skid-movable positive control may be maintained in the center of the positive control path by supporting the second and third legs of the pivot member on a front side of the piston and pressing the first leg of the pivot member into a vertex of the substantially v-shaped recess , Accordingly, the priority control can be moved from the center of the force control path along the force control path. In this case, the first foot of the pivoting element, which is pressed into the substantially V-shaped indentation, moved along. If the pivoting element between its three feet is pivotally mounted about a pivot axis, so the pivoting element is thereby pivoted, so that depending on the pivoting direction, only the second or the third foot of the pivoting element is supported on the piston. As the corresponding foot is moved towards the center of the ski, the piston is moved against the bias of the prestressed elastic element. At the same time, the force with which the piston is pressed against the pivoting element pushes the pivoting element back into its central orientation, in which the second and the third foot of the pivoting element are supported on the front side of the piston. Accordingly, the forced control is thereby driven back to the middle of the positive control path. In such a variant, there is additionally the possibility that the pivoting element or the pivot axis of the pivoting element is mounted displaceably in the longitudinal direction of the ski.

If the prestressed, elastic element is aligned in ski center in the ski longitudinal direction, but there is, in addition to these two preferred variants, the possibility that the prestressed elastic element differently cooperates with the positive control.

In addition, there is the possibility that the prestressed, elastic element is not aligned in the ski center in the ski longitudinal direction. For example, it may be aligned along the positive control path or along the dynamic range. But there is also the possibility that they are oriented differently and by their bias exert a force on a deflection mechanism, which deflects the action of the force in a direction along the forced control path or along the dynamic range.

The front-mounted machine preferably has a safety release position. In addition, the two levers in the holding position are advantageously movable to one end of the dynamic range, where that of the two levers, which includes the holding means, which is moved away on the dynamic path from the ski center, releasable by the positive control and the other of the two lever pivoted away is, whereby the front panel of the holding position in the safety release position can be brought. This has the advantage that a lateral safety release is made possible. Since the one of the two levers, which is in the direction of movement, is pivoted away, the corresponding holding means is pivoted away, whereby a captured in the holding position ski boot is released in its direction of movement as soon as the two levers are moved in the holding position to the corresponding end of the dynamic range , This has the advantage that in the event of a safety release, a continuous movement of the ski boot is ensured from a position held in the holding position to a release in the safety release position. Since, as already described above, a predefinable energy can be absorbed by the front automatic machine in the holding position during this process by the two levers being moved to one end of the dynamic range, this is a controllable, lateral safety release.

Preferably, in the holding position and in the safety release position, the two levers are each supported by a first link guide and a first sliding block mounted therein on the positive control. This has the advantage that the two levers are mounted on the positive control both in the holding position and in the safety release position. As a result, in particular a return of the front automatic from the safety release position is facilitated in the holding position.

As a variant, but it is also possible that, for example, one or both levers are stored only in the holding position by a first link guide and a first sliding block mounted therein on the positive control and are released in the safety release position by the corresponding first sliding block the corresponding first forced control is solved.

Instead of these variants, the two levers but also not be supported by a first link guide and a first sliding block mounted therein on the positive control. For example, the axes of the levers may be mounted on the positive control, while the levers are mounted on a further element of the front automatic machine by a first slotted guide and a first sliding block mounted therein. In this case, the levers can be stored both in the holding position and in the safety release position or only in the holding position on the other element.

Alternatively to these variants, however, the levers may also be mounted differently than by first slide guides and first sliding blocks on the positive control or on the further element. Such storage may be formed for example by a movable lever or piston connection.

If present, the first link guides preferably have a geometry, so that in the safety release position that of the two levers, which comprises the holding means which is moved away on the dynamic path from the ski center, is pivotable. In this case, the corresponding lever in the safety release position can be pivoted with a movement of the corresponding first sliding block in the corresponding first slide guide. This has the advantage that both in the holding position and in the safety release position, the two levers are mounted on the positive control or on the further element of the positive control and thus that a return of the front vending machine is facilitated by the safety release position in the holding position.

If first link guides are present and have such a geometry, the first link guides are preferably widened in a region in which in the safety release position of the corresponding first sliding block in the corresponding first link guide is movable when the corresponding lever is pivoted. This has the advantage that the one of the two levers, which is pivotable in the safety release position, is easier to move, since the corresponding first sliding block is loosely guided in this area of the corresponding first sliding guide and therefore between the corresponding first sliding block and the corresponding first sliding guide there is no or very little frictional resistance.

Preferably, the first slide guides also have a corner in their shape about which the corresponding first sliding block is moved when the corresponding lever is released in a transition from the locking position to the safety release position. This has the advantage that the lever is released immediately in a safety release and thus the transition from the holding position to the safety release position is carried out quickly.

Advantageously, the first slide guides on a geometry, so that in the safety release position that of the two levers, which comprises the one holding means which is moved on the dynamic path to the ski center, is fixed. This can be achieved, for example, in that the corresponding first sliding block abuts at one end of the corresponding first sliding guide. But this can also be achieved in that the corresponding lever is guided in such a way from the first link guide that it abuts on another stop and is thereby prevented from further movement. Both variants have the advantage that in the safety release position free movement of the corresponding lever is prevented. As a result, a controlled release of the ski boot can be achieved with a lateral safety release.

As a variant to but there is also the possibility that the first slide guides have a geometry, so that in the safety release position that of the two levers, which includes the holding means which is moved on the dynamic path to the ski center, within a limited range pivotally is while the other lever is free to pivot. Also, a controlled release of the ski boot can be achieved with a lateral safety release.

Alternatively, the two levers in the safety release position but also coupled by the geometry of the first link guides be pivotable, but that of the two levers, which includes the holding means which moves away on the dynamic path from the ski center, is proportionally stronger swiveling as the other lever is.

Preferably, the positive control is arranged in the safety release position skifest. If the positive control is movable in the holding position along the forced control path, the positive control can be prevented, for example, by an attack on a further movement beyond one end of the positive control travel. But there is also the possibility that one of the two levers in the safety release position is prevented by a stop at a further movement and prevents the forced control on a further movement by its storage on the positive control. If the two levers are mounted by a first link guide and a first sliding block on the positive control or on the further element of the front vending machine, but can also be achieved by a geometry of the first slide control that the positive control is arranged in the safety release position skifest.

Alternatively, the positive control in the safety release position but also be movable.

If the positive control is movable in the holding position and the front automatic comprises a biased in the ski center in the ski longitudinal direction, biased elastic element and the positive control has a substantially V-shaped recess, so are advantageously in outer regions of the two flanks of the v -shaped indentation troughs arranged. This has the advantage that, depending on the embodiment, for example, a roller bearing arranged at the tip of a piston acted upon by the prestressed elastic element with a force can interact with one of these hollows when the positive control is in the safety release position. In another embodiment, for example, a first foot of a pivoting element can thereby interact with one of these troughs when the positive control is in the safety release position. In both cases, the troughs have the advantage that the restoring force, which acts on the positive control by the piston or by the pivoting element and drives it to a center of the positive control travel, is minimized or completely eliminated in the safety release position. It does not matter if the forced control is arranged in the safety release position or is movable. However, by minimizing or eliminating the restoring force, the troughs can aid in the most preclusive control of the positive control in the safety release position.

As a variant, there is also the possibility that two troughs are arranged on a front side of the piston. This is particularly advantageous when the restoring force, which drives the positive control to a center of the positive control travel, is transmitted by a pivoting element. In this case, the second and the third foot of the pivot member may cooperate with one of these troughs when the positive control is in the safety release position. This variant also has the advantage that the restoring force, which drives the positive control to a center of the positive control path, is minimized or completely eliminated in the safety release position.

Alternatively, however, there is also the possibility that neither in outer regions of the two flanks of the substantially V-shaped recess in the positive control nor in the front of the piston two wells are arranged. Depending on the manner of the power transmission and such a design may be advantageous.

Preferably, the two levers are mounted in the release position on the positive control, so that the holding means of the two levers are at the first distance from each other. This has the advantage that the two levers and thus the distance of the two holding means in the release position can be controlled by the positive control.

Alternatively, the two levers in the release position may also be released from the positive control. But both levers should be stored at a transfer of the front vending machine from the release position in the holding position in each case on the positive control, in this transfer, the distance between the two holding means should be reduced from the first distance to the second distance. This can be implemented, for example, in that the two levers are mounted in the release position on a variable spacer. When transferring from the release position to the retaining position, the distance between the two retaining means can be reduced to the second distance and the two levers can be stored on the positive control by this variable spacer. The levers can be loosened from the variable spacer or remain supported on the variable spacer. Conversely, when the front panel is moved from the detent position back to the release position, the two levers should be released from the positive control and the distance between the two retainers should be extended to the first distance by the variable spacer. If the two levers in the holding position are not mounted on the variable spacer, they should first be able to be stored on the variable spacer. This alternative has the advantage that the distance between the two holding means is not changed by the positive control, whereby the positive control can be stably constructed and can withstand correspondingly larger forces.

Advantageously, the positive control comprises at least three elements, wherein one of the two levers on a first element and the other of the two levers is mounted on a second element, and wherein the first and the second element by at least a third element so relative to each other movable in that the two levers are moved apart in the release position and the holding means are at the first distance from each other and that the two levers are moved together in the arresting position and the holding means are at the second distance from each other. This has the advantage that the transfer of the front automatic from the release position to the holding position and back by the forced control is reached.

As a variant of this, the positive control may also comprise only two elements, wherein one of the two levers on a first element and the other of the two levers is mounted on a second element, and wherein the first and the second element are movable relative to each other in that the two levers are moved apart in the release position and the holding means are at the first distance from one another and that the two levers are moved together in the arresting position and the holding means are at a second distance from one another. This can be implemented, for example, in that the two elements of the positive control are connected to one another by a piston connection or by a screw connection. However, the two elements can also be connected to each other, for example, by a pivoting connection, wherein the holding means are moved apart or moved together by a pivoting movement of the two elements.

Alternatively, however, there is also the possibility that the positive control comprises only one element.

If the positive control comprises at least three elements, the first element and the second element of the positive control are preferably each supported by a second link control and a second sliding block on the third element of the positive control. Accordingly, the first and second members can be moved relative to each other by moving the third member relative to the first and second members, respectively. This has the advantage that an operation of the positive control is possible in a simple and cost-effective manner.

As a variant of this, however, there is also the possibility that the first element of the positive control comprises, for example, a rack which is guided in the second element and that the third element of the positive control is a pinion, by means of which the first and the second element of the positive control are movable relative to each other. Of course, other variants are possible in which the positive control comprises at least three elements.

In the presence of the second slotted guide, the third element of the positive control is preferably movable along the ski longitudinal axis, wherein upon movement of the third element of the positive control in a first direction, the first and the second element of the positive control are moved together by the second slotted guides and at Movement of the third element of the positive control in a second direction, the first and the second element of the positive control by the second slide guides are moved apart. It can be seen in the first and second direction in the longitudinal direction of the ski in the forward or backward direction or vice versa. Both have the advantage that the third element of the positive control for the transfer of the front vending machine is moved from the release position to the holding position and back in a direction which is independent of the oriented in the cross direction pivotal movement of the two levers. Accordingly, it can be prevented by the second slide guides that a force acting on one or both levers in the direction of the ski can cause a change in the relative positions of the first and the second element of the positive control. As a result, a simple and reliable control of the distance between the two holding elements is made possible in the release position and in the holding position.

As a variant of this, the third element of the positive control can not be moved along the ski longitudinal axis, but can also be designed to be rotatable about a rotation axis. In the presence of the second slotted guide, the first and the second element of the positive control can be moved together by the second slotted guides, for example during a rotation of the third element of the positive control in a first direction and the first and second rotation of the third element of the forced control in a second direction the second element of the positive control are moved apart by the second link guides. For this purpose, the second slide guides can be arranged spirally around the axis of rotation in the third element of the positive control or else in the first or second element of the positive control.

If the third element of the positive control is designed to be rotatable about the axis of rotation, then a bearing of the first and the second element on the third element can not be formed via the second slide guides. For example, the first element and the second element of the positive control can each be mounted by a rotary joint on the third element of the positive control, wherein upon rotation of the third element of the positive control in a first direction of rotation, the first and the second element of the positive control are moved together and at a Movement of the third element of the positive control in a second direction of rotation, the first and the second element of the positive control are moved apart.

Advantageously, the front automatic machine in a blocking position, in which the two holding means are at a third distance from each other, which is equal to or smaller than the second distance and in which the two levers are blocked in their movement. This has the advantage that the front automat can be blocked if a ski boot is held in the front automat, whereby it can be prevented that the ski boot can inadvertently free itself from the front automat. If a touring ski binding system with the front automatic machine is in the ascent position, the blocking position can thus prevent an unintentional loss of the ski. This could otherwise occur, for example, when the skis are lowered when making a sharp bend in a steep slope due to a lateral impact on the ski.

Alternatively, there is also the possibility that is waived this blocking position. This can be advantageous if, for example, the front-end machine is used by a skilled skier, who only wishes and / or requires a lateral safety release in the event of large lateral forces. In this case, the ski boot can be held sufficiently in the hold position by the front vending machine, whereby no blockage is needed. Accordingly, in this case, by dispensing with the blocking position of the front automatic constructively simpler and correspondingly easier to be formed.

Preferably, the positive control can be blocked in the blocking position. This means that the positive control is blockable in its movement, if it is movable in the holding position. If the positive control, however, is arranged in the holding position skifest, this means that the bearings of the two levers on the positive control in the blocking position can be blocked. Accordingly, the blocking of the positive control has the advantage that by blocking a single element, a movement of the two levers can be prevented. Accordingly, the front-end machine can be constructed more simply and manufactured more cost-effectively.

For blocking the positive control, for example, there is the possibility that the positive control can be blocked by a blocking element. For example, one or more blocking elements can be mounted on the positive control and can be pushed or pivoted for blocking into corresponding openings in the front automatic machine. But there is also the possibility that one or more blocking elements are mounted on the front automata and can be pushed or pivoted to block the positive control in corresponding openings in the positive control.

As a variant of this, however, there is also the possibility that one or both levers can be blocked in the blocking position. At the same time, the forced control can be blocked.

Advantageously, the front automatic machine comprises a control lever, which can be brought into a release position and a holding position, wherein the front automatic can be brought by positioning the control lever in the release position in the release position and by positioning the control lever in the holding position in the holding position. The control lever may be both a pivotable lever and a displaceable lever. Both have the advantage that the front panel can be easily controlled from the release position in the holding position and brought back.

As a variant of this, however, there is also the possibility that the front automaton comprises two control levers, wherein the front automat can be brought by a first of these two control levers from the release position to the retaining position and brought by a second of these two control levers of the detention position in the release position is.

As a further variant, there is the possibility that the front panel comprises a control lever, by which it can be brought only from the holding position in the release position. In this case, the front automat can for example comprise a tread spur, by which it can be brought from the release position into the retaining position, said tread spur can be actuated by a ski boot when the ski boot is properly positioned for entry into the front vending machine to the holding means. This has the advantage that for the skier an entry into the front automate is simplified. To have this advantage also in the two above-mentioned two variants, this tread spur can also be provided in addition to the one or the two control levers, which allow the transfer of the front vending machine from the holding position to the release position and back.

If the front automatic comprises at least one control lever and has a blocking position, so the control lever is preferably brought into a blocking position, wherein the front automatic can be brought by positioning the control lever in the blocking position in the blocking position. This has the advantage that the operation of the front automate is easy.

As a variant of this, however, there is also the possibility that the front-mounted machine comprises, for example, a separate control lever, by means of which the front-end machine can be brought into the blocking position, or else that the front-end machine does not comprise any control lever by means of which the front-end machine can be brought into the blocking position.

If the front automatic comprises at least one control lever and has a blocking position, the control lever preferably comprises at least one blocking element, by which the positive control in the blocking position can be blocked by the control lever is positioned in the blocking position. If the positive control in the holding position is movable, this can be done, for example, in that the blocking element engages in a recess in the positive control when the control lever is brought into the blocking position. But there is also the possibility that the control lever has two blocking elements, which surround a portion of the positive control or the entire positive control side and thereby prevent the positive control of their movement. However, if the positive control in the detent position is not movable, the control lever may for example comprise two blocking elements which, when the control lever is in the blocking position, engage the bearings of the two levers on the positive control and thereby block the positive control and movement of the levers ,

As a variant to the positive control, for example, not be blocked by at least one blocking element of the control lever, but otherwise. If the compulsory control comprises at least three elements, it can be blockable, for example, by blocking the third element. For this purpose, the third element of the positive control, for example in the longitudinal direction of the ski, can be moved into a lateral guide, but the third element can not be designed to be fully movable into the lateral guide in order to sufficiently prevent it from moving in a direction other than along the longitudinal direction of the ski and block accordingly. In order to remove the blockage, the third element of the positive control in the longitudinal direction of the ski can be made movable from the lateral guide, whereby it can be released for movement in a direction other than along the longitudinal direction of the ski. The lateral guide used in this example for blocking does not have to be a guide which completely surrounds the third element laterally. It may also be a rail-like guide on which the third element can be pushed. The movement of the third element blocked by the lateral guide should be that movement which can be carried out by the positive control in the arresting position. It may thus be both a linear movement in the direction of the cross-section and a turning or pivoting movement.

If the front automatic machine comprises a control lever, in this variant for actuating the blocking of the third element, for example, the third element can be moved by the control lever in the ski longitudinal direction. This can be achieved, for example, by the front automatic machine comprising a guide element in which the third element of the positive control is mounted. In this case, the third element can be pressed together with the guide element by a biased with an elastic element piston against the control lever and thereby be displaced according to the positioning of the control lever in the ski longitudinal direction. This has the advantage that, for example, at the same time the positive control can be designed to be depressible in the event of a deviation from a center of the positive control path through the elastic element to the middle of the positive control path. Furthermore, this has the advantage that the guide element is indeed pressed against the control lever, but does not necessarily have to follow the control lever. This has the advantage over a direct bearing of the guide element on the control lever that, for example, the control lever can be brought from the blocking position into the retaining position, whereby the guide element is moved against the prestressed piston. But if the control lever is brought from the retaining position to the blocking position, the control lever can be brought into the blocking position without movement of the guide member. For example, if the guide member is prevented from being displaced by the biased piston by an obstruction, the guide member can not be moved by the biased piston until the obstruction is removed. Thus, there is the possibility that the third element of the positive control for blocking is pushed into the lateral guide only when the positive control is correctly positioned to the lateral guidance. In a variant of this example, however, the control lever can also be brought from the retaining position to the blocking position, whereby the guide element is moved against the prestressed piston. If in this variant, however, the control lever is brought from the blocking position to the holding position, the control lever can be brought into the holding position without movement of the guide member. Depending on the design of the front automaton, this can be advantageous. As a further variant, the control lever can also be mounted directly on the guide element, or else the front automatic machine can not comprise any guide element. In this last case, for example, the positive control of the preloaded piston can be pressed against the control lever and / or the positive control can also be mounted directly on the control lever.

In addition to these variants, there is also the possibility that not only the third element of the positive control, but that the entire forced control as described for the third element in the longitudinal direction in and out of the lateral guide is movable. This is of course a variant which is possible even if the positive control comprises less than three elements.

Preferably, the holding means are pins, which are arranged on the respective lever so that they point starting from the respective lever with a free end to the ski center. This has the advantage that the ski boot, which can be held in the toe area in the automatic vending machine, can be mounted in a pivotable manner in the automatic vending machine in a pivotable manner about a horizontally oriented axis in the case of the ski boot, if the ski boot has two lateral recesses in its toe area.

In a first preferred variant thereof, the pins have pointed free ends. This has the advantage that the ski boot, which should be held in the front automatic, can be mounted precisely pivotable about the horizontally oriented in Skiquerrichtung axis in the front vending machine.

In a second preferred variant thereof, the pins have rounded free ends. This has the advantage that the ski boot can easily be detached from the front automat by a side safety release.

In a third preferred variant, the pins have tapering regions towards their free ends, the free ends of the pins being rounded. This has the advantage that by a suitable choice of the size of the tapered areas and the size of the rounded ends of the pins an optimization between precisely pivotable mounting of the ski to the horizontally oriented in the ski direction axis and good solubility of the ski boot from the front vending machine at a side Safety release can be achieved.

Alternatively, there is also the possibility that the holding means are designed differently.

From the following detailed description and the totality of the claims, there are further advantageous embodiments and feature combinations of the invention.

Basically, the same parts are provided with the same reference numerals in the figures.

Ways to carry out the invention

FIGS. 1a, 1b and 1c each show an oblique view of a front automatic machine 1 according to the invention. In FIG. 1a, the front automatic machine 1 is shown in a release position, in FIG. 1b in a holding position and in FIG. 1c in a blocking position. In all three FIGS. 1a, 1b and 1c, the front-end automatic machine 1 is oriented obliquely from the bottom right to the top left. If the front automatic 1 is mounted on a ski (not shown), corresponds in these figures below right at the back of the ski, while top left at the ski corresponds to the front. Therefore, in these figures, the ski longitudinal direction runs along an axis from bottom right to top left. Next corresponds in Figs. 1a, 1b and 1c top and bottom and the front vending machine 1 above and below.

The front automatic machine 1 comprises a housing 2, a control lever 3 and a tread spur 4 made of plastic. Further, the front automatic 1 comprises two pivoting levers 5.1, 5.2 made of aluminum, each with a retaining spurs 6.1, 6.2 made of steel. The two pivot levers 5.1, 5.2 are laterally, in the direction of the ski opposite each other, arranged. They are each pivotally mounted about an axis 9.1, 9.2 (see Fig. 3). These two axles 9.1, 9.2 are each arranged in a lower region of the front automatic machine 1 and are aligned in a plane lying parallel to the ski and converge rearwardly at an angle of 6 degrees to the ski longitudinal direction (see FIG. 10). Thus, the two pivot levers 5.1, 5.2 are pivotable substantially in the cross-machine direction. In an area above the axes, the two pivot levers 5.1, 5.2 are mounted on a positive control 20. Next, the two pivot levers 5.1, 5.2 above this storage depending on a pointing to the ski center side a control jaw 8.1, 8.2. Above the control jaws 8.1, 8.2, in an upper region of upwardly facing free ends of the pivot levers 5.1, 5.2, the two holding spurs 6.1, 6.2 are arranged facing the ski center. As a result, a ski boot can be supported by the holding spurs 6.1, 6.2 between the two pivoting levers 5.1, 5.2. The ski boot to be stored should have laterally mounted bearing bushes in a toe area, in which the retaining spurs 6.1, 6.2 can engage (see FIG. 2).

In front of the two pivoting levers 5.1, 5.2, the tread spur 4 is pivotably mounted about a transverse axis 7 oriented horizontally in the transverse direction of the ski in a ski center. A free end of the tread spur 4 extends above the positive control 20 to the rear between the two pivot levers 5.1, 5.2. In the release position (FIG. 1 a), the tread spur 4 is pivoted slightly upwards so that its free end is arranged above the housing 2. In the retaining position (FIG. 1b) and in the blocking position (1c), by contrast, its free end is folded downwards and lies on the housing 2.

In addition to the tread spur 4 and the control lever 3 is pivotally mounted about the transverse axis 7. A free end of the control lever 3, which serves to actuate, faces forward. In the release position (FIG. 1a), it points substantially horizontally forward. The control lever 3 is in a release position. In the holding position (Fig. 1b), however, the free end of the control lever 3 obliquely forward above, which corresponds to a holding position of the control lever 3. In the blocking position (FIG. 1c), the free end of the control lever 3 points steeply forwards and upwards. The control lever 3 is in a blocking position. Thus, the front automatic 1 can be brought from the release position to the holding position by the control lever 3 is pulled from the release position to the holding position. Starting from the detention position, the front automatic transmission 1 can be transferred further into the blocking position by the control lever 3 being pulled further from the detention position into the blocking position. In order to bring the front automatic 1 back into the holding position or the release position, therefore, the control lever 3 can be pressed down.

In the release position, the two pivot levers 5.1, 5.2 are slightly swung apart and the two holding spurs 6.1, 6.2 are at a first distance from each other (Fig. 1a). This first distance is sufficiently large so that a toe area of an upright ski boot can be moved between the two holding spurs 6.1, 6.2. In the holding position, the two pivoting levers 5.1, 5.2, however, slightly pivoted toward each other (Fig. 1b). Accordingly, here are the holding spurs 6.1, 6.2 at a second distance from each other, which is smaller than the first distance. The second distance is dimensioned such that the two retaining spurs 6.1, 6.2 can simultaneously engage from opposite sides in laterally mounted bearing bushes in the toe area of a ski boot and thereby store the ski boot. In the blocking position (FIG. 1c), the two pivoting levers 5.1, 5.2 are likewise slightly pivoted toward one another. Here are the two holding spurs 6.1, 6.2 at a third distance from each other, which is equal to or smaller than the second distance. Accordingly, a ski boot can also be stored in the blocking position by lateral engagement of the two holding spurs 6.1, 6.2.

In order to achieve a transfer of the front vending machine 1 from the release position to the holding position, in which a ski boot is stored in the front vending machine 1, the ski boot in an upright, parallel alignment with his toe area between the two pivot levers 5.1, 5.2 positioned and gently after to be moved down. Here, the tread spur 4 is pressed by a sole of the ski boot down, causing the front panel 1 is transferred to the holding position. When the ski boot is correctly positioned, the two retaining spurs 6.1, 6.2 engage in lateral bearing bushes of the ski boot, in that the two pivoting levers 5.1, 5.2 are moved together. At the same time, by depressing the tread spur 4, the control lever 3 is also pivoted up into the retaining position. In this transfer of the front automatic 1 from the release position to the holding position of the control lever 3 can also be simultaneously lifted manually from the release position to the holding position.

Behind the two pivoting levers 5.1, 5.2, the housing 2 has a guide bar 14, which extends in the transverse direction from a first side to a second side of the housing 2. This guide bar 14 is slightly raised relative to the rest of the housing 2 and serves to prevent a ski boot from being completely parked on the housing 2. In the case of a lateral safety release, it also serves to support a movement of the ski boot in the lateral direction and to prevent a sole of the ski boot can catch the rest of the housing 2. In order to optimize this function, the guide bar 14 may have in its upper region a sliding element on which the sole of the ski boot can slide. Such a sliding element may for example be made of Teflon.

2 shows a schematic oblique view of the front automatic machine 1 in the holding position with a ski boot 100 mounted in the front automatic machine 1. The ski boot 100 has two bearing bushes 101.1, 101.2 in its toe area, into which the two holding spurs 6.1, 6.2 engage. As a result, the ski boot 100 is mounted on the front automatic machine 1 so as to be pivotable about a horizontal axis oriented in the direction of the ski.

3 shows an exploded view of the front automatic machine 1. The perspective of the illustration is the same as in FIGS. 1a, 1b and 1c. In the exploded view, however, further components of the front automatic machine 1 can be seen, which are hidden in the FIGS. 1 a, 1 b and 1 c and in the case 2 in the housing 2. Thus, it can be seen in FIG. 3 that the front automatic machine 1 comprises a flat, metal-made bottom plate 30, which closes the otherwise downwardly open housing 2 against the bottom. The bottom plate 30 has four vertically aligned openings 31.1, 31.2, 31.3, 31.4 in a substantially square arrangement. When the front automatic 1 is assembled, these openings are 31.1, 31.2, 31.3, 31.4 in accordance with four vertically aligned openings 32.1, 32.2, 32.3, 32.4 in the housing 2. In the housing 2 is ever one of these openings 32.1, 32.2, 32.3 , 32.4 arranged in front of and behind the pivoting levers 5.1, 5.2. They serve to fasten by means of screws the front automaton 1 on a ski.

In an enclosed by the housing 2 and the bottom plate 30 interior of the front vending machine 1 a plurality of elements are arranged. Thus, a piston 35 made of plastic is arranged in a rear region of the housing 2 in the center of the ski. This piston 35 is aligned in the longitudinal direction of the ski. In an upper region, it has a guide aligned in its longitudinal direction, which can engage in a corresponding counterpart in the housing 2. As a result, the piston 35 is guided in the longitudinal direction of the ski. In its rear region, the piston 35 has an opening into which a spiral spring 36 oriented in the longitudinal direction of the ski is inserted. This coil spring 36 abuts with its rear end against a locking nut 37, which is screwed with a thread on an aligned in the longitudinal direction of adjustment screw 38. In the mounted state of the front automatic machine 1, a head of the adjusting screw 38 is mounted in an opening 39 in a rearwardly directed side wall of the housing 2. The adjusting screw 38 is rotatable from the outside through the opening 39.

In front of the piston 35, a guide element 50 made of plastic is mounted in the housing 2. This guide element 50 has in each case a rearwardly facing arm in a rear region on both sides. In the mounted state of the front automatic machine 1, the piston 35 is gripped on both sides of these arms from the front. Next, the guide member 50 in a front region on both sides each have a forward facing, short arm. These two arms each comprise an upwardly pointing nubs 51.1, 51.2 in a front region. Towards the rear, these two arms are delimited from a central region 53 of the guide element 50 by a plate oriented vertically and in the direction of the ski, forming a front stop 52. This central region 53 is plate-shaped and oriented horizontally. To the rear, it is delimited by the two arms pointing backwards, which extend upward to above a plane of the central region 53 and thereby form a rear stop. On the central region 53, the positive control 20 is movably mounted in the transverse direction. In this case, it is guided between the front stop 52 and the rear stop and accordingly prevented from moving in the longitudinal direction of the ski relative to the guide element 50.

As can be seen here in the exploded view, the positive control 20 comprises two side levers 20.1, 20.2 and a control plate 20.3. The latter is, as described above, movably mounted in the guide element 50 in the transverse direction. On either side of the control plate 20.3, one of the two side levers 20.1, 20.2 is arranged aligned in each case in the cross-machine direction. The mounting of the two side levers 20.1, 20.2 on the control plate 20.3 each consist of a second slide guide 21.1, 21.2 in the control plate 20.3 with a second sliding block 22.1, 22.2 mounted therein, which is attached to the corresponding side lever 20.1, 20.2. The second slotted guides 21.1, 21.2 are aligned such that they allow a relative movement of the control plate 20.3 to the side levers 20.1, 20.2 in the ski longitudinal direction, whereby the two side levers 20.1, 20.2 are pulled together or pushed apart. At the outer ends of the side lever 20.1, 20.2, the two pivot levers 5.1, 5.2 are mounted. For this purpose, the side levers 20.1, 20.2 each comprise a first slotted guide 23.1, 23.2, in each of which a first sliding block 24.1, 24.2 arranged on the corresponding pivoting lever 5.1, 5.2 is mounted. In this case, the first sliding blocks 24.1, 24.2 are arranged on the respective pivot lever 5.1, 5.2 above the axles 9.1, 9.2, about which the pivot levers 5.1, 5.2 are mounted pivotably on the housing 2.

In addition to the second slide guides 21.1, 21.2, the control plate 20.3 has two notches 27.1, 27.2, which are arranged side by side on a forwardly oriented side of the control plate 20.3. In this two incisions 27.1, 27.2 can be attached to the control lever 3 attached bars 28.1, 28.2. As a result, the control plate 20.3 can be prevented in the blocking position from moving in the transverse direction.

In the assembled state of the front automatic machine 1, the coil spring 36 is biased between the piston 35 and the lock nut 37. To the rear, it is supported on the locking nut 37 and the adjusting screw 38 on an inner side of the housing 2. By turning the screw 38, whereby the lock nut 37 is moved forward or backward, while the bias of the coil spring 36 can be adjusted. Accordingly, the coil spring 36 pushes the piston 35 with an adjustable force to the front, where the piston 35 is supported against the control plate 20.3. For this purpose, the piston 35 has a laterally rounded, front end with a horizontal slot. In this slot, a round steel disk 40 is aligned horizontally and rotatably supported about a vertical axis 41. With this steel disk 40, the piston 35 abuts in a laterally flattened recess 25 in the control plate 20.3. When the control plate 20.3 is laterally moved in the guide element 50, the steel plate 40 rolls out of the indentation 25 along the corresponding flank of the laterally flattened indentation 25 in the control plate 20.3 (see FIGS. 8a, 8b and 8c). In this case, the piston 35 is pressed against the bias of the coil spring 36 to the rear. Because of the obliquely oriented to the spring edge of the recess 25 while a restoring force is exerted on the control plate 20.3, which drives the control plate 20.3 in a central position in the guide member 50, in which the steel plate 40 at a lowest point in the recess 25 of the control plate 20.3 is located. Therefore, by adjusting the bias of the coil spring 36, the strength of the restoring force can be adjusted. As also shown in FIGS. 11a and 11b, there is the possibility that the lateral flattened indentation 25 laterally each have a trough 42.1, 42.2, in which the steel plate 40 of the piston 35 can engage when the front automatic 1 in the safety release position located. As a result, in the safety release position, the restoring force acting on the control plate 20.3 can be minimized or completely eliminated.

FIGS. 4a, 4b and 4c show three different views of the front automatic machine 1 in the release position. In Fig.4a, the front panel 1 is shown from below, with the bottom plate 30 and the guide member 50 (see Fig. 3) are hidden. 4b shows a vertical longitudinal section through the front automatic machine 1 running along the ski center, and FIG. 4c shows a vertical cross section through the positive control 20 seen from the front.

As can be seen in Fig. 4a, the control plate 20.3 relative to the two side levers 20.120.2 moved backwards, whereby the second sliding blocks 22.1, 22.2 are located at a front end of the second slotted guides 21.1, 21.2. Since the second slotted guides 21.1, 21.2 in the control plate 20.3 diverge from back to front, the two side levers 20.1, 20.2 are thereby moved apart. Accordingly, the two pivot levers 5.1, 5.2 are swung apart. Since the two side levers 20.1, 20.2 are not displaceably mounted in the housing 2 in the longitudinal direction of the ski, but only in the transverse direction, the control plate 20.3 in the housing 2 is displaced to the rear in a rearward position. Accordingly, the piston 35 is pressed against the coil spring 36 to the rear.

Fig. 4b shows that the control lever 3 is in the release position and that the tread spur 4 is pivoted upwards. In addition, it can be seen that the tread spur 4 extends in its front region in the control lever 3 and has an upwardly pointing shoulder 10, which adjusts with its rear edge against a downwardly facing counterpart 11 of the control lever 3. Therefore, the control lever 3 is pivoted up when the tread spur 4 is pressed down or the tread spur 4 is pivoted up when the control lever 3 is pivoted down to the release position.

4b it can be seen that the control plate 20.3 is guided in the guide element 50 and that the piston 35 presses from behind with the steel disk 40 against the control plate 20.3 forward. In this case, the control plate 20.3 is held in its rear position by the guide member 50 with the front stop 52 forward against a arranged on the control lever 3 grid 12 abuts (see also Fig. 6d).

In cross-section, which is shown in Fig. 4c, the bearing of the two pivot levers 5.1, 5.2 can be seen on the side levers 20.1, 20.2. It can be seen that the first sliding blocks 24.1, 24.2 are located at an upper end of the first slide guides 23.1, 23.2. In a region of these upper ends, the first slotted guides 23.1, 23.2 extend a short distance in the vertical direction downwards. Then they make a kink from the center of the ski to the outside and extend arcuately outward and increasingly down. Furthermore, it can be seen in FIG. 4c that the two side levers 20.1, 20.2 have incisions 26.1, 26.2 running in a lower region in the horizontal direction from the outside to the center of the ski. In these cuts 26.1, 26.2, the axes run 9.1, 9.2, by which the two pivot levers 5.1, 5.2 are pivotally mounted on the housing 2. If the existing of the two side levers 20.1, 20.2 and the control plate 20.3 Priority control 20 is moved in Skiquerrichtung, the cuts 26.1, 26.2 are arranged on the skifest on the housing 2 arranged axes 9.1, 9.2.

FIGS. 5a, 5b and 5c show the same views of the front automatic machine 1 as FIGS. 4a, 4b and 4c. In contrast to FIGS. 4a, 4b and 4c, the front automatic machine 1 is in the arresting position in FIGS. 5a, 5b and 5caber.

In Fig. 5a it can be seen that the control plate 20.3 and the piston 35 are in the holding position slightly further forward than in the release position (see Fig. 4a). Accordingly, the second sliding blocks 22.1, 22.2 are located in a central region of the second slide guides 21.1, 21.2. Since the second slotted guides 21.1, 21.2 diverge from back to front, thereby the two side levers 20.1, 20.2 are slightly contracted compared to the release position. Therefore, the two pivot levers 5.1, 5.2 are pivoted together.

FIG. 5 b shows that the tread spur 4 is pivoted down about the transverse axis 7 and rests on the housing 2. In addition, it can be seen that the control lever 3 is slightly swung up and is in the holding position. Compared to the release position (see Fig. 4b), the piston 35 and the control plate 20.3 are slightly shifted forward. In contrast to FIG. 4b, in FIG. 5b, the guide element 50 is hidden.

In the cross section (Fig. 5c) can be seen how the two pivot levers 5.1, 5.2 are pivoted together, whereby the two holding spurs 6.1, 6.2 are at a second distance from each other. As in the release position (see Fig. 4c), are the first sliding blocks 24.1, 24.2 at the upper ends of the first slotted guides 23.1, 23.2. In contrast to the release position but as already mentioned, the two side lever 20.1, 20.2 contracted. Accordingly, the axes are 9.1, 9.2, by which the two pivot levers 5.1, 5.2 are pivotally mounted on the housing 2, slightly further out in the incisions 26.1, 26.2 of the two side levers 20.1, 20.2.

FIGS. 6a, 6b and 6c show the same views of the front automatic machine 1 as FIGS. 4a, 4b and 4c and 5a, 5b and 5c, respectively. In FIGS. 6a, 6b and 6c, however, the front automatic machine 1 is in the blocking position.

It can be seen in FIGS. 6a and 6c that the two side levers 20.1, 20.2 and the control plate 20.3 are located essentially at the same position as in the arresting position (see FIGS. 5a and 5c). Further, it can be seen in Fig. 6b that the control lever 3 is pivoted further in the blocking position. He is in the blocking position. The tread spur 4 is pivoted downwards as in the arresting position and rests on the housing 2. As a result, the shoulder 10 of the tread spur 4 is located further forward under the control lever 3 and does not touch the counterpart 11 of the control lever 3.

6d, similar to FIG. 6b, shows a vertical longitudinal section through the front automatic machine 1 in the blocking position. However, the vertical longitudinal section does not run along the center of the ski, but is slightly offset from the center of the ski to the side. It passes through one of the two forwardly extending arms of the guide element 50 and through the arranged on this arm nubs 51.2. As a result, the screening 12 can be seen, which is arranged on the control lever 3 in a region below the transverse axis 7. With this screening 12, the control lever 3 presses on the two knobs 51.2 of the forwardly facing arms of the guide element 50. The further the control lever 3 is pulled in the blocking position up, the farther the grid 12 is pulled over the nubs 51.2 of the guide member 50. The guide element 50 and the control plate 20.3 mounted therein are also pulled forwards in the longitudinal direction of the ski. Since the second sliding blocks 22.1, 22.2 are thereby contracted by the second slide guides 21.1, 21.2, the two side levers 20.1, 20.2 and the two pivot levers 5.1, 5.2 are further contracted with the retaining spurs 6.1, 6.2 (see FIG. 6a). Therefore, in the blocking position, the holding spurs 6.1, 6.2 are at a third distance from each other which is equal to or smaller than the second distance. How big the third distance is effective depends on the ski boot, which is stored in the front automatic 1. Compared to the holding position, in which holding spurs 6.1, 6.2 are at a second distance from each other, the two holding spurs 6.1, 6.2 contracted in the blocking position by pulling up the control lever 3 until they are present in the lateral bearing bushes of the ski boot. By this queuing is about the pivot lever 5.1, 5.2 and the positive control 20 prevents further pulling up of the control lever 3. How far the control lever 3 in the blocking position is hochziehbar, thus depends on the width of the ski boot, or from the distance of the lateral bushings in the toe area of the ski boot.

This contraction of the two retaining spurs 6.1, 6.2 in the blocking position can also be done by a somewhat modified mechanism. For example, the forwardly extending arms of the guide member 50 may have a grid, which extends substantially semicircularly forwardly upwards, wherein the radius of curvature decreases towards the top. In this modification can be arranged per knob on the control lever 3 per side in the region below the transverse axis 7 each. With these nubs, the control lever 3 can press on the two grids of the forward facing arms of the guide member 50. The farther the control lever 3 is pulled upwards in the blocking position, the farther the nubs are pulled over the latches of the guide element 50. The guide element 50 and the control plate 20.3 mounted therein are pulled forwards in the longitudinal direction of the ski by virtue of the upwardly tapered radius of curvature of the rasters. By means of the second slotted guides 21.1, 21.2 and the second sliding blocks 22.1, 22.2, the two swivel levers 5.1, 5.2 can be pulled together with the holding spurs 6.1, 6.2.

In addition to the contraction of the two holding spurs 6.1, 6.2 in the blocking position, the two bars 28.2 are inserted into the corresponding cuts 27.2 in the control plate 20.3 by pulling up the control lever 3 (see FIG. 3). Thereby, a movement of the control plate 20.3 and thus the entire positive control 20 is blocked in Skiquerrichtung.

When the control lever 3 is pivoted from the blocking position down to the holding position, the grid 12 is moved away from the nubs 51.2 of the guide member 50 to the rear. The screening 12 abuts the first stop 52 of the guide element 50. If now the control lever 3 is further pivoted down to the release position, the grid 12 pushes the first stop 52 to the rear. Thereby, the guide member 50 is moved with the control plate 20.3 mounted therein against the piston 35 and against the bias of the coil spring 36 to the rear (see Fig. 4b).

FIGS. 7a, 7b and 7c each show a vertical cross-section through the automatic front-end control 20 through the front automatic machine 1 and a schematically illustrated section through a lower region of the ski boot 100. The sequence of the figures illustrates a lateral safety release of the Front automatic 1. Here, the ski boot 100 is released in the illustration to the right from the front panel 1. When viewed in the ski forward direction, the movement of the ski boot 100 indeed runs to the left. Here, however, the terms "right" and "left" refer to the illustration shown.

In FIG. 7a, the front automatic machine 1 is in the holding position. The representation corresponds to the representation of the front automatic machine 1 shown in FIG. 5c. The additional schematic illustration of the ski boot 100 shows how the ski boot 100 is mounted in the front automatic machine 1. As a result, it can be seen that a lower region of the sole of the ski boot 100 almost touches the control jaws 8.1, 8.2 of the two pivoting levers 5.1, 5.2. The existing from the control plate 20.3 and the two side levers 20.1, 20.2 Priority control 20 is centered in the front automata skimittig 1. As already described, the positive control 20 can be moved but in Skiquerrichtung in the holding position. (This movement is blocked in the blocking position.) In such a movement, the two pivoting levers 5.1, 5.2 are coupled within a dynamic range coupled in the direction of the ski about the axes 9.1, 9.2. As a result, the two holding spurs 6.1, 6.2 coupled in the second distance to each other on a dynamic path in Skiquerrichtung moves. This is shown in FIG. 7b. Here is the front panel 1 is still in the detention position. However, the two pivot levers 5.1, 5.2 are pivoted right to almost to one end of the dynamic range and the positive control 20 is moved almost to one end of a positive control travel. Since the two pivot levers 5.1, 5.2 are pivoted to the right, the two holding spurs 6.1, 6.2 are moved together with the ski boot 100 to almost to one end of a dynamic path. In this position, the lower region of the sole of the ski boot 100 on the right touches the control jaw 8.1 of the corresponding pivoting lever 5.1. As a result of this impact on the control jaw 8.1, the holding spur 6.1 of this pivot lever 5.1 is just released from the corresponding bearing bush 101.1 of the ski boot 100. Accordingly, the retaining spores 6.1 can not dig into the bushing 101.1 of the ski boot 100 and also can not prevent a solution of the ski boot 100 from the front automatic machine 1 by getting caught with the sole of the ski boot 100.

[0120] In the state in which the positive control 20 is centered in a ski-centered manner, the two first sliding blocks 24.1, 24.2 are substantially above the axles 9.1, 9.2 about which the two pivoting levers 5.1, 5.2 are pivotable (FIG. 7a). When the positive control 20 is moved to the right, the two pivot levers 5.1, 5.2 are pivoted to the right. As shown in Fig. 7b, so that the first two sliding blocks 24.1, 24.2 are pivoted to the right. Due to their arrangement relative to the axes 9.1, 9.2, the two first sliding blocks 24.1, 24.2 also moved slightly downwards. Therefore, they are no longer at the upper end, but between the upper end and the kink of the first slide guides 23.1, 23.2.

When the positive control 20 is moved to the right to the end of the positive control travel and the two pivot levers 5.1, 5.2 are pivoted to the right to one end of the dynamic range, so are the first two sliding blocks 24.1, 24.2 in the bend of the first Slotted guides 23.1, 23.2. In this case, due to the geometry of the first slide guides 23.1, 23.2, the first sliding block 24.2 of the left pivot lever 5.2 abuts against the first slide guide 23.2 of the corresponding side lever 20.2 and thus prevents the positive control 20 from moving further to the right. At the same time, the positive control 20 is moved so far to the right that the first sliding block 24.1 of the right pivot lever 5.1 is released from the bend in the first slide guide 23.1 and can move freely in the arcuate portion of the first slide guide 23.1 of the corresponding side lever 20.1.

As a result, the right pivot lever 5.1 tilt freely down, causing the front panel 1 is in a safety release position (Fig. 7c). When the right pivot lever 5.1 is tilted away, the ski boot 100 is released from the front vending machine 1 and released.

7a, 7b and 7c illustrate lateral safety release of the front automatic machine 1. The front automatic machine 1 is located in the representations in each case in the same positions as in the illustrations of FIGS. 7a, 7b and 7c. However, FIGS. 8a, 8b and 8c respectively show the front automatic machine 1 from below, wherein the bottom plate 30 and the guide element 50 (see FIG. 3) are hidden.

FIG. 8a corresponds to FIG. 5a. It shows the positive control 20 consisting of the control plate 20.3 and the two lateral levers 20.1, 20.2, centered in the front automatic machine 1 in a skim-centered manner. FIG. 8b shows the positive control 20 in a position close to the end of the positive control path. Accordingly, the two pivot levers 5.1, 5.2 are pivoted almost to the end of the dynamic range. Further, Fig. 8c shows the positive control 20 at the end of the positive control path. The two pivot levers 5.1, 5.2 are pivoted to the end of the dynamic range, wherein the pivot lever 5.1, which is in the pivoting direction, released by the positive control 20 and tilted down.

As already described in connection with FIG. 3, the control plate 20.3 has a laterally flattened indentation 25. Since the control plate 20.3 in Figs. 8b and 8c is moved away laterally from its skimittigen position, the piston 35 is pressed by the corresponding edge of the recess 25 in the control plate 20.3 out of the recess 25 against the bias of the coil spring 36 to the rear. Due to the obliquely oriented to the spring force edge of the recess 25 while a restoring force is exerted on the control plate 20.3, which drives the control plate 20.3 back to its skimittige position. By this restoring force and by the way, which travels a stored in the Vending machine 1 ski boot from its skimittigen position to the end of the dynamic path, maximum energy is given, which can accommodate the front panel 1, without causing a lateral safety release , This maximum energy can be adjusted by the bias of the coil spring 36 by adjustment by the screw 38 and the lock nut 37.

The lateral safety release, which is illustrated in FIGS. 7a, 7b, 7c, as well as 8a, 8b and 8c, can also be carried out on the other side, not shown here. The triggering process is the same.

The front automatic 1 not only allows a lateral safety release, but also a trigger in the forward direction. This Frontalauslösung can take place when the front panel 1 is in the hold position or in the blocking position. To illustrate this, FIG. 9 shows a vertical longitudinal section through the front automatic machine 1 in the blocking position. In this case, a ski boot 100 is stored in the front vending machine 1. One heel of the ski boot 100 is free, whereby the ski boot 100 with the heel is pivotally upwards. The ski boot 100 is shown tilted forward accordingly, with a toe portion 102 of the ski boot 100 touches the control lever 3. When a skier using a front vending machine 1 crashes forward, the ski boot 100 may be tilted farther forward than shown in FIG. When the front automatic 1 is in the blocking position as shown in FIG. 9, in such a fall, the control lever 3 is depressed from the toe portion 102 of the ski boot 100 from the blocking position to the holding position, whereby the front automatic machine 1 is transferred from the blocking position to the holding position , If now the ski boot is tilted even further forward, the control lever 3 is pushed even further down. The two pivot levers 5.1, 5.2 are pivoted apart and the ski boot 100 is released from the front vending machine 1. For this purpose, the control lever 3 does not have to be pressed completely from the retaining position into the release position and the front automatic machine 1 does not have to be completely transferred to the release position. It is sufficient if the ski boot 100 presses the control lever 3, starting from the holding position slightly down and the two pivot levers 5.1, 5.2 are slightly swung apart.

The front-end machine 1 can be used in a touring ski binding system together with an automatic heel unit (not shown). In such a system, the automatic heel unit should allow storage of the ski boot 100 in a heel area.

Accordingly, such a system allows a downhill position in which the front-end machine 1 is in the hold position and in which the ski boot 100 is mounted in the toe area in the front automatic 1 and in the heel area on the heel unit. Furthermore, such a ski binding system allows a climbing position in which the ski boot 100 is mounted in the front automatic 1 and released by the heel machine. In this ascent position, the front automatic 1 can be in the holding position or in the blocking position. It allows in both positions, a pivoting movement of the ski boot 100 to a Skiquerachse and accordingly allows a walking motion of a skier.

[0130] As described above, the front automatic machine 1 enables a lateral safety release in the arresting position. When a ski boot 100 is mounted in a touring ski binding system with the front vending machine 1 and the towing ski binding system is in the downhill position, the towing ski binding system thereby enables a lateral safety release. For example, if the ski boot 100 is supported on the heel counter by rearward-facing retaining spurs, the ski boot 100 can pivot in such a lateral safety release. He is only solved laterally from the front vending machine 1, while he is still held by the holding spurs of the heel unit. As soon as the ski boot 100 has been detached from the front automatic machine 1, it can also be detached from the heel counter by being moved away from the holding spurs of the heel counter and / or turned away. Accordingly, a lateral safety release option is unnecessary by the heel counter. It is sufficient if the automatic heel unit allows a safety release in the forward direction.

The front automatic machine 1 is optimized for a lateral safety release in a touring ski binding system, in which the automatic heel unit does not allow lateral safety release. This optimization is illustrated in FIG. 10, which shows a plan view of the front automatic machine 1 in the holding position with the ski boot 100 held therein. Thus, two dashed lines are shown in FIG. 10, along which the axes 9.1, 9.2 (see FIG. 3) about which the two pivoting levers 5.1, 5.2 are pivotable are aligned. 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. Since the automatic heel unit does not permit a lateral safety release, the ski boot 100 becomes a vertical axis during a lateral safety release rotated in the vicinity of the point 16 until it is released from the front panel 1. As a result, the pivotal movement of the pivot lever 5.1, 5.2 lying in the direction of movement runs perpendicular to the direction of movement of the ski boot 100. Accordingly, the alignment of the axles 9.1, 9.2 is optimized for a rotational movement of the ski boot 100 in the event of a lateral safety release.

As can be seen from FIGS. 8a, 8b and 8c, this optimization results in the two side levers 20.1, 20.2 of the positive control 20 not being aligned along a straight line extending at right angles to the ski longitudinal axis. They are each aligned at right angles to the corresponding axis 9.1, 9.2 and thus deviate each by 6 degrees from a straight line, which is aligned perpendicular to the ski longitudinal direction from.

Similar to FIGS. 8a and 8b, FIGS. 11a and 11b show the front automatic machine 1 in the holding position or in a position in which the positive control 20 is located at the end of the positive control path. In this case, the front panel 1 is shown from below, with the bottom plate 30 and the guide member 50 are hidden. 11c, in turn, shows the front automatic machine 1 in the holding position from below, the bottom plate 30 being hidden while the guide element 50 is shown.

The front-end automatic machine 1, which is shown in FIGS. 11a, 11b and 11c, has two differences compared to the front-mounted machine 1 shown so far. These differences illustrate further possible embodiments of the front automatic machine 1. The first difference is that the piston 35 is guided by a nub in a cut oriented in the longitudinal direction in the guide element 50 (see FIG. 11c). Since the piston 35 is guided upwards and downwards in the longitudinal direction of the ski, a better guidance in the longitudinal direction of the ski results for the piston 35, so that a better force transmission is achieved by the piston 35 on the control plate 20.3, whereby friction losses are minimized. The second difference is that the laterally flattened recess 25 laterally each have a trough 42.1, 42.2, in which the steel plate 40 of the piston 35 can engage when the front automatic 1 in the safety release position (see Fig. 11a and 11b) is located. As a result, in the safety release position, the restoring force acting on the control plate 20.3 can be minimized or completely eliminated. Accordingly, the Wegschenken the corresponding pivot lever 5.1 is facilitated, since by the minimized or canceled repulsive force, a frictional resistance for the pivotal movement of the pivot lever 5.1 is also minimized or canceled.

FIGS. 12a, 12b and 12c show a similar view of the front automatic machine 1 as FIGS. 11a, 11b and 11c, wherein FIGS. 12a, 12b and 12c illustrate a further possible embodiment. Here, the piston 35 has no steel disk 40 at its tip. Instead of the steel disk 40, 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 oriented pivot axis 44. Towards the front, it has a rounded, first foot 45.1, which engages in the laterally flattened indentation 25 of the control plate 20.3. On both sides of the ski center, the pivoting element also has a rearwardly directed second or third foot 45.2, 45.3 behind the pivot axis 44. When the positive control 20 is in the middle of the positive control travel, these two feet 45.2, 45.3 are supported rearwardly against the piston 35 (see FIG. 12a). When the positive control 20 is moved along the positive control path, the first foot 45.1 of the pivot member 43 is moved, whereby the pivot member 43 is pivoted about its axis 44 (see Fig. 12b). In the process, the foot 45.2 of the pivoting element, which lies in the direction of movement of the positive control 20, pushes the piston 35 backwards, while the other foot 45.3 no longer touches the piston 35. As a result, the pivoting element 43 is acted upon by the piston 35 on one side by the piston 35 on one side with the forwardly directed force, a torque acts on the pivoting element 43, which drives back the positive control 20 in the middle of the positive control path via the first foot 45.1 of the pivoting element 43 ,

When the positive control 20 is moved to one end of the positive control travel, the second or third foot 45.2, 45.3 of the pivoting element 43 touching the piston 25 engages in a corresponding recess 46.1, 46.2 in the front side of the piston 35 (FIG 12b). As a result, the power transmission between the piston 35 and pivot member 43 is minimized or eliminated, whereby the restoring force acting on the positive control 20 is minimized or completely eliminated. Accordingly, the pivoting away of the corresponding pivoting lever 5.1, 5.2 is facilitated, since by the minimized or canceled repulsive force, a frictional resistance for the pivoting movement is also minimized or canceled.

In the Fig. 12c, the front vending machine 1 is shown in the holding position from below, wherein the bottom plate 30 is hidden, while the guide member 50 is shown. As a result, it can be seen that in this embodiment, the pivot axis 44 of the pivoting element 43 is mounted in the guide element 50, wherein the Schenkachse 44 but something in the longitudinal direction is movable. It is thereby achieved that, in the blocking position, the piston 35, together with the pivoting element 43, can follow the movement of the control plate 20.3 (here obscured by the guide element 50) in the longitudinal direction of the ski.

FIGS. 13a and 13b each show a vertical cross-section through the automatic front-end control unit 1, as seen from the front. In both figures, the positive control 20 of the front-end automatic machine 1 is located at one end of the forced-control path. In FIG. 13a, the embodiment shown in FIGS. 11a, 11b and 11c is shown, whereas in FIG. 13b, the embodiment shown in FIGS. 12a, 12b and 12c is shown. Both differ from the previously described embodiments that the arcuate portions of the first slide guides 23.1, 23.2 are wider towards the bottom. As a result, the first sliding blocks 24.1, 24.3 can move in the arcuate section of the first slide guides 23.1, 23.2 with less frictional resistance. As a result, the Wegschenken the corresponding pivot lever 5.1, 5.2 is facilitated in the safety release position.

Independently of the possible embodiments described in FIGS. 11a, 11b, 11c, 12a, 12b and 12c, this widening of the arcuate sections of the first slide guides 23.1, 23.2 can also be provided in the case of the embodiment of the front automatic machine 1 shown in FIGS , There is the possibility that the first slotted guides 23.1, 23.2 as shown here are wider towards the bottom, or that they are constantly wider over the entire arcuate sections than at their upper ends.

Compared to the embodiments shown in the preceding figures, the retaining spurs 6.1, 6.2, which are shown in FIGS. 13a, 13b, have rounded free ends. As a result, it can be achieved that the ski boot can be released more easily from the front automatic machine 1 in the event of a lateral safety release. However, this worsens the storage of the ski boot in the front vending machine 1 something. Accordingly, there is the possibility that the front automatic 1, the shape of the free ends of the retaining spurs 6.1, 6.2 optimized between optimal storage of the ski boot and optimal solubility of the ski boot from the front vending machine 1. It should be noted that the holding means can also be designed entirely differently than the holding spurs 6.1, 6.2 shown here.

Of course, the invention is not limited to the embodiments of the front automatic machine 1 described above. Various other embodiments are possible. Thus, for example, the first slotted guides not 'on the positive control, but be arranged on the housing of the front automata and vice versa, the two axes can be arranged on the positive control instead of the housing.

In addition, for example, both the first and the second slide guides can be replaced by other guides. One way to do this is to use dovetail guides with a carriage guided thereon.

Another possible embodiment is that the bearing of the two pivot levers on the positive control is arranged below the axes, about which the pivot levers are pivotable.

As a further variant, the two pivot levers in the holding position, for example, be stored fixed to the positive control. In this case, the two pivot levers are movable in the holding position together with the forced control in the cross-machine direction. The dynamic range then corresponds to the forced control path. For example, in this embodiment, when the urging control is moved to an end of the urging control path, the pivoting lever in the direction of the urging control can be released from the constraint and tilted about the axis in the direction of movement. In this case, the axes about which the pivot levers are pivotable, for example, be arranged on the positive control and be moved along with the positive control along the forced control path.

In order to allow in such an embodiment, the pivoting away the pivot lever lying in the direction of movement, for example, a guide for the pivot lever can be arranged on the housing of the front automatic, which releases the corresponding pivot lever as soon as the end of the positive control travel is reached. But it is also conceivable that the positive control at the end of the positive control travel abuts an obstacle, whereby a release mechanism is operated on the positive control, which releases the corresponding lever for a pivoting movement.

The invention is not limited to these variants of the front-end vending machine. There are also other embodiments possible.

In summary, it should be noted that a front-end automatic is created which increases the safety for a skier.
