Description

The invention relates to a heel holder for a touring ski binding, comprising a housing structure which is connectable to a ski via a base structure, and a machine which is pivotally connected to the housing structure. The heel holder further comprises a securing element which is connected to the housing structure, which from a first position in which an entry is possible with a ski boot in the heel holder for a downhill to a second position in which the entry into the ski boot in the Heel holder is locked, can be moved. Finally, the heel holder comprises a ski brake with at least one brake element, which can be adjusted between an abutment position in which a movement of the ski on a ground is possible, and a braking position in which it slows down a movement of the ski on the ground.

When descending with a touring ski binding, it should be ensured that the ski brake secured while walking on the ski is released, so that the ski can be slowed down in the event of a fall or other release from the ski boot and does not travel unchecked downhill. Especially when it comes to freeride bindings, which can also be used for touring, it is very important that a safe downhill with the freeride binding, for example, in deep snow and rough terrain is possible. That is, the toe holder must be prepared to connect a ski boot for touring in a pivot axis with the ski, and to secure for departure by, for example, a hold-down in the toe holder. A side release must be guaranteed, as well as the trouble-free functioning of the ski brake when driving off.

It is therefore an object of the invention to provide a heel holder for a touring ski or freeride binding which can also be used for touring, with which the use of the ski for the departure with secured ski brake reliably prevented. Another object of the invention is to provide a touring ski binding.

This object is achieved by the heel holder with the technical features of claim 1. Advantageous developments are disclosed in the dependent claims and / or described in the description and shown in the figures.

A first aspect of the invention relates to a touring ski binding, in particular a freeride binding, which is also suitable for touring ascent, for a ski boot. The touring ski binding includes a toe holder and a heel cup that can assume a first configuration in which the binding can be used for walking and a second configuration for riding off with the binding. The toe holder is constructed so that a ski boot can be connected with its front end to the toe holder in a position for walking and in another position, which is different from the position for the downhill. In particular, a ski boot defined in the toe holder is located further forward in a walking configuration in the longitudinal direction of the ski and further down the ski seen in a downhill configuration in the longitudinal direction of the ski. In the position for walking, the sole holders of the toe holder may be, for example, pins that engage in corresponding receptacles on the ski boot sole and define a pivot axis about which the ski boot can be pivoted when walking. In the further position for the departure of the sole holder can be formed by at least one hold-down, which presses from above and / or the side of the ski boot sole. The touring ski binding further comprises a ski brake connected or connectable via the base structure or housing structure, which is adjustable between an abutment position in which a movement of the ski on a ground is possible, and a braking position in which a movement of the ski is braked on the ground , For walking with the binding, the preferred ski brake is additionally set in a safety position on the ski. In a downhill, this securing position must be solved so that the brake remains active and can be adjusted in the event of a fall, for example, in the braking position, in which the brake brake associated brake elements preferred Spring force can intervene in the snow. The brake elements may preferably be designed in the form of brake paddles known from the prior art.

In particular, the pins may be two bearing portions opposite each other with respect to a longitudinal axis of the ski which cooperate in the configuration for walking with the corresponding seats on the sides of the ski boot sole facing them which form an abutment for the bearing portions. The pins or bearing sections can be moved by pivoting the sole holder substantially transversely to the ski longitudinal axis into the counter bearing and out of the counter bearings. In the pivoted state, the anvil and the bearing elements received therein define in the configuration for walking a pivot axis transverse to the ski longitudinal axis and connect the ski boot in the pivot axis pivotally connected to the touring ski binding. In the swung-out state, in which the bearing elements no longer engage in the anvil, the touring ski binding is in an open position, so that the user can get on or off the ski binding in the touring ski binding or a change to the configuration for departure can take place.

The heel holder comprises a housing structure, which can preferably be fixedly connected to a base structure. It further comprises a machine connected in a pivot joint to the housing structure and pivotable between a closed position and an open position of the heel holder. In the downhill position, the machine must necessarily be in a closed position, so that the heel holder, or at least one sole holder enclosed by the heel holder, connects the ski boot to the ski, and thus a safe downhill is possible. The closing of the heel holder for the downhill position can be done either by boarding the ski boot in the heel holder via a correspondingly integrally formed on the machine tread surface or by manual operation. In the walking position, the toe holder may be in both the closed position and the open position. In both positions, a walking movement, ie pivoting of the ski boot about a pivot axis on the toe holder, is allowed here, without the heel holder having this Movement difficult or impeded. The base structure may in this case be connectable as a separate element to the ski or be integrally connected to the ski or formed as part of the ski.

As Automat is here the part of the heel holder referred to, which includes the sole holder (s), which connect safely in the position for the departure, the ski boot with the ski. The automat may comprise a spring element with which a triggering force can be set, in which the heel holder triggers, for example, in the event of a fall on the descent. At the heel holder, a climbing aid or more climbing aids may be provided, which moves from a rest position in a Steighilfeposition, for example, can be pivoted. With several climbing aids, these have different climbing angles.

Finally, the heel holder comprises a securing element with which the entry point is blocked with a ski boot in the heel holder for touring ski binding in downhill mode, for example, if a ski brake, which is connected to the housing structure or the base structure or the ski, set in the securing position to the ski is. In other words, the safety element, for example, prevent the use of the ski with the touring ski binding for downhill, as long as the ski brake is not released to swing in a known manner from the ski in the direction of the ground and thereby achieve their braking effect. The securing element thus acts as a blocking or blocking element which prevents in the blocking position that the heel end of the ski boot can be accommodated in the heel holder by the securing element forms a vertical stop for the ski boot sole or the machine, which in particular prevents the ski boot in the heel holder can be lowered to a footprint for the heel end of the ski boot.

Preferably, the securing element may be moved relative to the base and the housing to move from a resting or boarding position, in which the ski can be used with the touring ski binding for departure, in a lock or Get in the boarding position, in which the ski can be used with the binding for walking.

The movement of the securing element may be a raising or lowering, a rotary or pivoting movement, but preferably the movement is a purely linear movement, with which the securing element is moved from the rest position to the locked position and back. In particular, the movement can take place in a plane which runs essentially parallel to the ski surface. The movement can take place in and against the skiing direction, that is, along a central longitudinal axis of the ski or the binding.

The securing element is in the rest position behind the heel end of the ski boot preferably in the region of the housing below the machine. In this position, he does not obstruct the movement of the machine in the closed position for the departure. In the locked position, the securing element can form a stop for the machine on which the machine is applied, before it can be pivoted to the position in which the ski boot can secure in the touring binding for departure.

Preferably, the securing element in the locked position forms a support for the ski boot, respectively the underside of the ski boot sole at the heel end of the ski boot, so that the ski boot can not so far in the touring ski binding, respectively the heel holder, board, that the machine completely pivoted to the ski boot sole can be. The movement of the machine comes even before reaching the position in which the sole holder can act on the ski boot sole to secure the ski boot for the descent in the heel holder, in contact with the heel end of the ski boot. That is, the user can not pivot the heel holder in both cases so far that it can engage on, at or in the rear end of the ski boot sole. Thus, the ski boot is not connected to the ski, a departure with the ski therefore not possible.

When the automaton is biased in the closed position and the open position by a spring element, it can automatically pivot back to the open position if the closed position is not reached, so that the user can not falsely assume that his attempt has been made to the automaton, e.g. for a departure to pivot into the closed position was successful.

The securing element may in particular be a bumpkin, that is, the stop or the stops are formed as local elevations on a plate or plate-like surface.

Preferably, the securing element is also in the locked position behind the rear end of the ski boot sole when the ski boot is held in the touring position in the touring position.

In a less preferred embodiment of the securing element, at least one front in the skiing direction, pointing away from the local elevations end of the plate of the bumpkin in the locked position to reach below the heel end of the held in the position for walking in toe holder ski boot. In this case, this end forms a footprint for the heel end of the ski boot when walking in flat terrain. In the preferred embodiment, the complete securing element, that is, the plate and cusp or bumps, lie in the locked position and in the boarding position behind the heel-side end of the ski boot in the walking position in the walking position so that the plate does not constitute a contact patch. In this case, the footprint for the ski boot is essentially formed by the brake pedal.

The heel holder may further comprise a locking plate which is connected or connectable to the securing element. About the locking plate or by means of the locking plate, the securing element can be moved preferably by hand without the use of a tool in the locked position and from the locked position to the boarding position.

It should be noted that the term "locking plate" denotes a special component, without the term "sheet" contained therein meaning a material restriction in the way that the locking sheet must be formed from a sheet metal or sheet metal. It may also be formed from a plastic, a carbon fabric, a composite material (multilayer) or other suitable material. The locking plate can also be referred to as a spindle plate.

Preferably, the locking plate may be connected to the securing element such that movement of the locking plate results in movement of the securing element in the same direction, substantially the same way and at the same speed, and vice versa. Preferably, the movement is a linear motion. An at least low pivotability of the securing element relative to the locking plate can be given by the fact that the locking plate is connected to the securing element in at least one pivot joint, that is, for example, with an axis held in two bores.

An integrally formed on the housing structure or connected to this receiving area may include or form a receptacle and / or a guide for the locking plate. As a result, it can be avoided, for example, that the locking plate bulges or evades laterally when the movement from the entry position to the blocking position is made more difficult, for example, by snow or ice in the heel holder. This can advantageously avoid that the movement of the locking plate is not completely transferred to the security element. The receiving area may have on its surface facing the ski surface additional guide means, such as a projection or a groove, which engage the longitudinal and / or lateral positioning in corresponding means of the base structure. This is particularly advantageous if the heel holder is adjustable relative to the base structure or the ski in order to adapt the binding to different ski boot sizes can.

The locking plate may have at its end facing away from the securing element a handle or lever, which can be preferably by hand, especially by hand without the use of a tool, gripped to move the locking plate together with the securing element. Preferably, the handle or the lever may be connected in a first rotary or pivot joint with the locking plate and in a different from the first rotary or pivot joint second rotary or pivot joint.

In this case, the axes of the first and the second pivot joint can extend transversely to a longitudinal axis of the ski, preferably parallel to a ski surface. The axes of the first rotary joint and the second rotary joint may also be aligned parallel to each other.

Preferably, the free end of the lever, that is, the end which is not connected to the receiving area, in the direction of the ski tip, when the securing element is in the locking position, respectively, in the direction of the ski when the securing element is in the boarding position. The lever is connected to the receiving area at a ski front end of the receiving area, whereby the lever is disposed in an area on the ski which lies beneath the sole of a ski boot received in the binding, irrespective of the position of the securing element. This means that the lever does not need to be additionally secured when the binding is used for departure. In contrast, a fuse of the lever in the locked position of the fuse element may be useful. The fuse can be done for example by the lever in an over-center position.

When the user uses the ski for downhill skiing, he stands with the ski boot on a brake pedal of the ski brake, whereby the brake elements are pivoted laterally to the ski, so that they can not intervene in the driving surface. The lever is in the position in which it lies above the connecting plate, preferably below the depressed brake pedal, so that it is secured against, of to swing back to the position in which the securing element is active and obstructs the movement of the ski brake.

The locking plate may be connected directly to the securing element. Preferably, the locking plate comprises at its securing element facing the end of a connecting structure which is fixedly connected to the locking plate, for example, welded, glued, riveted or screwed, or urgeformt together with the locking plate. The connection structure is prepared so that it can be connected to the securing element.

The locking plate may include a holding member that can be moved in unison with the locking plate and the securing member, the holding member securing the ski brake in the securing position on the ski when the securing member is in the locked position for walking, and releasing the ski brake for descent, when the securing element is in the boarding position. The holding element can at least partially surround the mutually facing, mutually parallel regions of the brake arms, so that they can not swing away from the top of the ski in the load-free state and thereby the brake elements can not engage in the ground to decelerate the ski. The holding element may be mushroom-shaped, with a mushroom foot which is moved between the brake arms and a screen-shaped head which at least partially overlaps the brake arms.

A backup of the ski brake in the securing position by the holding element takes place virtually automatically when the securing element in the locked position and the ski boot in the toe holder in the front position are held in the pins (corresponds to the walking position). The first time the ski boot is lowered into the binding, the brake pedal of the ski brake is pressed against the ski surface. The brake arms are pressed in the mutually parallel central areas on the support member. Due to the shape of the holding element, the mutually parallel, opposing central areas of the brake arms are pressed apart elastically and return elastically to their original Position back when the brake arms reach the area of the retainer foot. The brake arms are now below the umbrella-shaped head of the support member, the ski brake can no longer trigger, but is secured in the side adjacent to the ski position by positive engagement.

The heel holder may further comprise a coupling element which forms part of a footprint for the ski boot and a linear guide for the securing element. The coupling element may be firmly connected to the housing structure, for example screwed or positively and / or non-positively connected, so that the coupling element can not come loose from the housing structure.

The coupling element may have at least one guide, for example a guide slot or a guide groove, in which a preferably formed on the underside of the securing element guide body engages to give the fuse element a guide, in particular a linear guide.

Another aspect of the invention relates to a ski touring binding with a toe holder which can receive the toe end of a ski boot sole, so that the touring ski binding can be used for walking and for downhill, and a heel holder, as described in the first aspect. Preferably, the toe-side end of the ski boot sole is connected to the toe holder in a position for walking and connected in a further position when the touring ski binding is used for downhill. The position to go is different from the position for the departure. In the position for walking, a distance of the toe-held toe-side end of the ski boot to the ski rear end of the ski is greater than the distance held in the toe holder toe-end of the ski boot in the further position for departure. In the position for walking, the sole holders of the toe holder may be, for example, pins that engage in corresponding receptacles on the ski boot sole and define a pivot axis about which the ski boot can be pivoted when walking. In the position for the departure of the sole holder be formed by at least one hold-down, which presses from above and / or the side of the ski boot sole.

The touring ski binding further comprises the above-described securing element, which lies behind the heel end of the ski boot both when walking and when skiing downhill with active ski brake, so that the securing element is not touched by the ski boot, or when walking to below the heel end of the ski Ski boot is enough and a climbing aid forms, at the downhill with active ski brake but behind the heel-side ski boot end. When attempting to enter into the touring ski binding in the configuration for the descent, while the ski brake is still secured for walking, the securing element prevents, as already described in detail to the first aspect, the entry into the touring ski binding, respectively the heel holder.

The heel holder of the touring ski binding comprises at least one sole holder, which may be a pin or a hold-down or a combination of pin and hold-down.

The toe holder and the heel holder are preferably fixedly connected to the base structure. However, this does not mean that the toe holder and / or heel holder can not be adjusted relative to the base structure in order to adapt the binding to different ski boot sizes.

In the following, an embodiment will be explained in more detail with reference to figures, without thereby the subject of the invention is to be limited to the embodiment shown. Essential features of the invention, which can only be taken from the figures, are included in the disclosure of the invention and can advantageously further develop the subject matter of claim 1 individually or in combinations.

The FIG. 1 shows in an exploded view an embodiment of a heel holder 1 of a touring ski binding having the features of the invention. The heel holder 1 is arranged on a base structure 2 and comprises a housing structure 3 and an automatic machine 6. The touring ski binding comprises a ski brake 4. Further, the heel holder 1 comprises a securing element 5 which can be connected to a locking plate 7. Further parts are a coupling element 14 and a holding element 13 with which the ski brake 4 can be fixed or secured or held on a ski, not shown, for walking with the ski in a safety position.

The housing structure 3 of the heel holder 1 can be pushed onto the base structure 2 in the exemplary embodiment and fixed there in a position that is dependent on the size of the user's shoe, for example. The heel holder 1 includes all parts, such as a return spring, a spring element for setting a release force, optional means for a side release in case of overload during departure, at least one climbing aid, etc., as they have known heel holder for touring ski bindings. The machine 6 is also a known machine 6, which moves from a closed position to an open position can be pivoted. The pivoting of the machine 6 from the open position to the closed position can be done on the one hand by a contact of the ski boot sole with a molded tread 6a of the machine 6, ie by climbing the ski boot sole from above on the tread surface 6a or by a manual operation of the machine.

Apart from the possibility of adjustment for adaptation to a ski sole size, the heel holder 1 is firmly connected to the basic structure 2 and does not have to be displaced linearly relative to the basic structure 2 in order to change the touring ski binding from the walking mode to the downhill mode.

The ski brake 4 comprises two brake arms 4b, each with a brake element 4a, which is designed in the form of a brake paddle, which are mechanically connected in a known manner with a brake pedal 4d, so that at a load and a discharge of the brake pedal 4d, for example by the user when getting in and out of the touring ski binding, the brake arms 4b are pivoted into an abutment position and a braking position. In the first, loaded position, the brake paddles 4a abut on one side edge of the ski, so that a descent with the ski is possible. In the second, unloaded position, the brake paddles 4a are down from the ski and can intervene in the pad, for example the snow, to decelerate the ski, for example, after a fall. For walking, the position of the brake arms 4b is additionally secured in the securing position, so that they remain in the contact position even when relieved.

In order to prevent the user from forgetting to release the ski brake 4 when changing from the walking position to the position for the downhill, so that the ski brake 4 can pivot into the braking position during a fall, for example during a fall on the descent, the movement comprises Heel holder 1, the securing element 5. The securing element 5 has the shape of a hump with in the embodiment of a plate-shaped base 5a and two of the base 5a upwardly projecting humps 5b, and two of the base 5a down to the ski, projecting Connecting elements 5c. The fuse element 5 may be molded in one piece together with the bumps 5b and the connecting elements 5c, for example by injection molding or a generative process such as 3D printing. Alternatively, the parts, that is, the base 5a and the bumps 5b having the connecting members 5c, or the base 5a, the bosses 5b and the connecting members 5c may be separately manufactured parts joined to the securing member 5. In this case, the base 5a and / or the bumps 5b and / or the connecting elements 5c may be made of a single material or of different materials.

The function of the fuse element 5 will be apparent from the following figures. First of all, it should be said that the securing element 5 can be moved from a first position, which is also referred to as a boarding position, to a second position, which is referred to as a blocking position. In the entry position of the securing element 5, the user can get into the touring ski binding and thereby pivot the machine 6 either by pressing the tread 6a or by manual operation in its closed position in which he can act on the ski boot sole, so that the ski boot for a downhill safely kept in the touring ski binding. In the locked position, the securing element 5 prevents movement of the machine 6 in the closed position by the securing element 5 of the embodiment forms a footprint for the heel end of the ski boot sole, which prevents the ski boot to fully enter the heel holder 1. As a result, the machine 6 comes to rest on the ski boot before the sole holder 16 can act on the ski boot sole 19. This signals to the user that he can not take off with the touring ski binding, but must first release the ski brake 4 or ski brake safety device before he can leave.

The securing element 5 of the exemplary embodiment can be connected to a locking plate 7. The locking plate 7 comprises a securing element 5 facing the end 7 b with a connecting structure 12 which can be connected to the securing element 5. In the embodiment has the connection structure 12 has two fork-shaped ends each with an engagement groove 12a and openings 12c in which axes 12b can be supported. For connecting the connecting structure 12 with the securing element 5, the axes 12b can pass through through-holes 5d in the connecting elements 5c of the securing element 5. A linear movement of the locking plate 7 can thus be transferred to the securing element 5 essentially without play, at the same time the securing element 5 can be pivoted relative to the locking plate 7 in the axle bodies 12, apart from a play that the connecting elements 5c have in the engagement grooves 12a.

In order to move the locking plate 7 linear, the locking plate 7 can be connected at its front, facing away from the securing elements 5 end 7a with a lever 9. The lever 9 is connected via a first axle body 10 with a front end 18a of a receiving area 18 in the skiing direction and at the same time via a second axle body 11 with the front end 7a of the locking plate 7. The lever 9 can be about a rotational axis D1 of the first axle body 10 of a position in which it lies partially in front of the locking plate 7, in a different position in which it is almost completely on or above the locking plate 7, to be pivoted and thereby displace the locking plate 7 linearly by a distance which is twice the distance between the Rotation axis D1 and a rotation axis D2, in which the lever 9 is connected to the locking plate 7 corresponds. At least in the position in which the lever 9 is partially in the ski direction in front of the locking plate, he can take a Übertotstellung that prevents him unintentionally moved out of this position in which the securing element 5 is in the locked position out.

The receiving area 18 may be urgeformt together with the housing structure 3 in one piece or form a separate housing to the housing part 3, which can be connected to the housing structure 3 or joined.

Connected to the locking plate 7 is also a holding element 13, which can be moved together with the locking plate 7 in and against the skiing direction. In the exemplary embodiment, the retaining element 13 is a screw which can be screwed into a threaded body 13 a firmly connected to the locking plate 7. The holding element 13 forms a holding element head 13b and a holding element foot 13c. During the movement of the locking plate 7 with the securing element 5 in the locking position of the securing element 5, the holding element 13 is pushed into a position in which the holding element 13 seen in the longitudinal direction of the ski at the height of two mutually opposite, substantially mutually parallel central regions 4c the brake arms 4b is located. Will the user now use the binding to go, is pushed by boarding a ski boot and thus by pressing on the brake pedal 4d of the Halteelementfuß 13c between the central regions 4c of the brake arms 4b. The holding element head 13b at least partially overlaps the brake arms 4b in this region 4c and thereby prevents the brake 4 from being pivoted relative to the ski in the load-free state. The brake 4 is thus in the securing position. The brake arms 4b with the brake paddles 4a are on the side of the ski, the touring ski binding can now be used for walking. The release of this lock can then be achieved by pivoting the lever 9 when the ski boot has dropped out. Thus, the holding element 13 is now at a rear portion 4e of the brake arms 4b. In the rear area 4e, the brake arms 4b run apart, as a result of which the holding element head 13b is released by the brake arms 4b and an unlocking of the brake 4 is effected.

Finally, the shows FIG. 1 nor a coupling element 14 which can be connected to the housing 3. In the exemplary embodiment, the coupling element 14 is connected to the housing 3 such that it can not be moved in or against the skiing direction relative thereto. The coupling element 14 has two guides 15, in which the connecting elements 5c of the securing element 5 are guided when the securing element 5 is moved in and against the skiing direction from the entry position to the locked position and back. The coupling element 14 may form an uprising surface 17 for the ski boot sole on its front side remote from the securing element 5.

The FIG. 2 shows the assembled heel holder 1 in a perspective view from above, with the securing element 5 in the Einsteiposition. The ski boot is in the touring ski binding in the FIG. 2 in the position for the departure. The lever 9 is in this position of the securing element 5 on or above the locking plate 7, the ski brake 4 is in the investment position and is relieved, that is, it can trigger or is active. This is achieved in that the holding element 13 rests freely on the rear portion 4e of the brake arms 4b. The securing element 5 with the base 5a and the humps 5b is disposed within the housing structure 3 of the heel holder 1 and allows the machine 6 with the sole holders 16 can be pivoted so far that he can press on a ski boot sole to the ski boot on the touring ski binding firmly connect with the ski for a downhill.

The FIG. 3 shows the heel holder 1 of FIG. 2 with a ski boot sole 19 of a ski boot held in the ski binding in the position for departure. The ski boot sole 19 lies with its end facing the machine 6 on the brake pedal 4d, which thereby forms a footprint for the ski boot sole 19, on. The sole holder 16 rest on the ski boot sole 19 and press the ski boot sole 19 in the direction of the surface of the ski, not shown.

At the heel holder 1 facing away from the front of the ski boot sole 19 Pinaufnahmen 20 are formed, can engage in the pins of the front jaw or toe holder, not shown, to connect to the ski boot on the ski boot sole 19 pivotally connected to the ski. The ski boot sole 19 forms in the area in front of the Pinaufnahmen a direction of skiing projecting area 21, which can serve to ensure that the downhill ski touring binding by means of a strap or other security against unwanted loosening, preferably so that the touring ski binding for example, in a fall can trigger. The bracket or the other securing device are preferably firmly connected to the toe holder and can take an active position in the downhill and be moved to go with the touring ski binding in a passive position.

That is, in the walking position of the ski boot is pivotally held at its toe end in the pins. In the downhill position, the pins are no longer in engagement with the pinholes of the ski boot sole 19, the ski boot is now held at its toe-side end by the one or more hold-downs in the touring ski binding. The ski boot is in the walking position in a first or forward position on the ski where it is at a first distance from a ski tip forward in the skiing direction and in a downhill position in a second or rear position where it has a second Distance greater than the first distance ski tip has.

The FIG. 4 shows in an enlarged detail view of the heel holder 1 entered ski boot sole 19 of a ski boot, which is in the touring ski binding in the position for departure. The ski boot is fully supported on the brake pedal 4d. The ski brake 4 is in the abutment position. As a result, the brake arms 4b and the brake paddles 4c connected to them lie next to the ski and above the ski surface substantially parallel to a longitudinal axis L of the ski. The lever 9 is also under the ski boot sole 19 and therefore can not unintentionally loosen, so that it requires no additional assurance for the lever 9 in the Einsteigposition of the fuse element 5.

The bumps 5b of the bumpkin or the securing element 5 are in the ski direction behind the heel end of the ski boot sole 19. The sole holder 16 press on the ski boot sole 19 and secure the ski boot in the touring ski binding for departure.

The FIG. 5 essentially corresponds to the FIG. 3 , only that in the FIG. 5 the securing element 5 is in the blocking position. The ski boot sole 19 can not anymore be lowered to the surface of the brake pedal 4d, which has the consequence that the machine 6 can not be pivoted so far that the sole holder 16 can get into a securing engagement with the ski boot sole 19. The lever 9 is now at least partially in front of the front end 7a of the locking plate 7 and the support member 16 is now in the position in which it secures the ski brake 4 in the securing position. The lever 9 may for example be in an over-dead position, so that the lever 9 is secured against unintentional release from the position shown.

The FIG. 6 shows an enlarged detail view of FIG. 5 , The ski boot stands with the ski boot sole 19 on the securing element 5, or the hump (s) 5b. The securing element 5 is in the locked position, in which the machine 6 can not set the ski boot in the touring ski binding for departure.

In this position of the ski boot sole 19, the machine can not be pivoted so far that he can safely secure the heel end of the ski boot sole with the sole holders 16 in the heel holder 1, since he already before the Achieve the necessary position to a heel end of the ski boot is applied. In this position, the sole holders 16 can not act on the ski boot sole 19 to secure the ski boot in the touring ski binding for departure.

The FIG. 7 shows a central longitudinal section through the heel holder 1 of FIG. 2 , In the FIG. 7 is to see the holding member 13, which does not define the ski brake 4 in the position shown in the securing position, that is, that the holding element 13 abuts at the level of the rear portion 4e of the brake arms 4b and is thus released. Thus, the relieved ski brake 4 can push the brake arms 4b with the brake paddles 4a away from the ski, down into the ground, for example snow or ice, to prevent the ski from traveling unchecked in the valley direction, for example after a fall.

The machine 6 is shown in the position in which he can actively act on the ski boot sole to secure the ski boot in the touring ski binding for departure. The hump 5b of the securing element 5 is arranged behind the sole holders 16 and hinders neither entry into the touring ski binding nor pivoting of the machine 6 in this position.

The FIG. 7 further shows the heel holder 1, which is arranged in a known manner longitudinally adjustable on the base structure 2. Via an additional projection 22 on the underside, ie the side facing the ski surface, the receiving area 18 and a corresponding engagement of the projection 22 in a corresponding guide groove 23 of the base structure 2, a longitudinal positioning and lateral support of the heel holder 1 is further promoted. The projection 22 is formed so that the cross section at the skinahen end has a larger area than at the Skifernen end. As a result, by the correspondingly shaped guide groove 23, a vertical hold of the receiving area 18 on the base structure 2 is additionally made possible.

In the FIG. 8 the two positions are shown, which occupies the ski boot in the touring ski binding a) for the downhill and b) while walking, with only the heel side end is shown and thus the positioning of the ski boot relative to the heel holder 1. In a third figure c) is the Ski boot in the toe holder held in the downhill position, but the ski brake 4 was not released and is in the safety position.

If the touring ski binding, which may be in particular a freeride binding, is used for the downhill a), the ski boot must be held in the ski binding at the toe end in a toe holder, not shown, and in the heel holder 1 at the heel end, and establish a secure connection of the ski boot with the ski. The ski brake 4 must be active. That is, the brake paddle 4 a of the ski brake 4 must be as long as the user is firmly in the binding and thus on the brake pedal 4 d, lie laterally on the ski in the investment position, in which they can not interfere with the ground and thereby hinder the ski in its forward movement.

When heel holder 1 of the embodiment is in the departure position, the securing element 5 in the Einsteigstellung in which it is located below the machine 6 so that the user when he enters the touring surface 6a when getting into the touring ski binding, the machine 6 in the position takes along, in which he secures the heel-side ski boot end in the touring ski binding.

When using the touring binding for the ascending or walking b), the ski boot is held at its toe end in the toe holder, not shown, that it can be pivoted about an axis, wherein the heel end is free from the heel holder 1. That is, the heel end of the ski boot is no longer depressed by the heel holder 1 on the ski and held there, but is spaced in the embodiment of the heel holder 1. In the walking position b) of the touring ski binding, the ski brake 5 must be secured in the securing position such that the brake arms 4b can not be pivoted relative to the ski, regardless of whether or not the user is standing with the ski boot on the brake pedal 4d.

In the heel holder of the embodiment, the ski brake 4 is secured in the securing position by the holding member 13. In order to achieve this, the securing element 5 must first be manually moved from the entry position by means of the locking plate 7 as already described by the user (see also FIG FIG. 8 a) be moved in the blocking position shown. To adjust the security element 5 of the ski boot is not in the touring ski binding. If the user now enters the touring ski binding with the ski boot and for the first time lowers the ski boot onto the ski, he presses the brake pedal 4d of the ski brake 4 onto the ski. In this case, the middle portions 4c of the brake arms 4b are pressed onto the mushroom-shaped holding element 13, so that the holding element head 13b elastically presses apart the central regions 4c of the brake arms 4b, the middle regions 4c overcome the holding element head 13b and behind the holding element head 13b in the region of the Haltelementfußes 7c elastically spring back to the original position before the elastic pressing apart.

The securing element 5 in the locking position causes the user, when he changes with the toe-side end in the toe holder from the walking position b) to the departure position a), whereby the ski boot relative to the ski against the skiing direction, that is, on the heel holder is offset, can only enter the touring ski binding, if previously the fuse element 5 was moved by hand in the boarding position. Only when the securing element 5 is in the boarding position, the ski brake 4 is again active, so for example in the event of a fall during the departure trigger and occupy the braking position and thus decelerate or stop the ski separated ski, in which the brake pad 4a at load-free brake pedal 4d can engage in the ground.

In a third figure c) the situation is shown in which the ski boot in the toe holder is already held in the position for departure, but the user has forgotten to release the ski brake 4, so that it is still fixed in the securing position. The ski boot sole 10 is now on the bumpkin 5b of the fuse element 5, so that the user can not close the machine 6 for departure.
