Description

Technical field

The present invention relates to a telemark ski binding according to the preamble of independent claim.

State of the art

When skiing and / or touring in the so-called Telemark style, skiing is included removable heel (also called free heel) not only climbed, but also drove down. During the descent, telemark skiing will do that Cornering made with a lunge. To do this, the shoe heel be lifted off the top of the ski on the inside of the curve. in the In contrast to conventional ski touring bindings, which are only used for ascending free heel are provided, with hardly any significant steering forces when climbing the ski must be transferred, for telemark ski bindings (i.e. ski bindings that are suitable for telemark skiing) also in the position with the heel raised the ski can still be controlled.

Previous bindings suitable for telemark skiing (i.e. so-called telemark ski bindings) include a toe attached to a ski a front sole retainer to hold the shoe sole down on the Toe. The shoe heel is held in place by means of a cable pulling device and springs essentially resiliently fixed to the front jaw. Perpendicular to the longitudinal direction of the ski the heel is left free to allow the heel to lift off the shoe. When the heel is lifted off, the sole of the Telemark ski boot moves lengthways bent, the foremost part of the shoe sole through the Sole retainer is held down firmly on the top of the ski. This allows the Skiers still have the ski firmly enough over the heel even with the heel lifted off steer the Telemark ski boot associated with the ski by using the soccer and Toe area steering forces are transferred to the ski.

The cable pulls of previous Telemark ski bindings have the disadvantage that they wear through relatively often when used due to their heavy use become. In order to avoid unwanted tearing of the cable pulls, they must be regularly maintained and replaced if necessary. There is also a boarding into the binding without manually operating the cable pulling device (so-called Step-in function) not possible.

Presentation of the invention

The object of the present invention is to provide a telemark ski binding, which with the cable pulls of previous Telemark ski bindings overcomes related disadvantages.

The solution to the problem is the subject of the independent claim.

According to the invention, a telemark ski binding has a fixed (i.e. immovable) and non-pivotable) on a ski attachable toe piece. At the Front jaw is non-swiveling with respect to a cross to the longitudinal direction and a front sole retainer running parallel to the top of the ski arranged around the sole of the shoe on or in the area of the toe on the ski hold down. On one of the shoe tips towards the shoe heel set back position is a carrier on a holding part that can be firmly attached to the ski articulated on which a buttock with a rear sole hold-down is arranged to the shoe sole on or in the region of the shoe heel on the carrier hold down.

Because the buttock is carried by the wearer with the rear sole hold-down is not a cable for holding the shoe heel for the binding according to the invention required, which means that with the cable pulls of previous Telemark ski bindings associated disadvantages are eliminated. The carrier is articulated on the holding part such that the Heel of a Telemark ski boot from the Ski lifted off and in one by the longitudinal direction and the Surface normal to the ski top defined level can be pivoted. By articulating the wearer on one of the toes in the direction of Shoe heel set back on the one hand and that with respect to a cross to Ski longitudinal direction and non-pivoting axis parallel to the top of the ski Arranging the front sole retainer on the other hand ensures that the Sole of a Telemark ski boot that can be bent in the longitudinal direction, in the soccer or The tip of the toe is still partially on the ski, even when the heel is raised attached front cheeks or the top of the ski. Through contact between the sole of the shoe in its foremost area and the toe piece The top of the ski becomes the one required for steering when telemark skiing Power transmission from the ball and / or toe area to the ski enables.

In contrast to the previously known Telemark ski bindings with one Cable pulling device in which entry into the binding without actuation of the Cable pulling device by hand is not possible with the inventive Telemark ski binding through appropriate training of the buttocks So-called step-in function can be created so that to get into the Binding no binding parts have to be operated by hand.

The holding part is preferably an integral part of the toe piece formed, the carrier being articulated on the same piece of the toe piece that also carries the front sole hold-down. This allows the relative position of the Carrier articulation point with respect to the position of the sole hold-down corresponding design of the toe can be specified precisely. As As an alternative to this, the holding part can also be designed as a separate part the toe piece supporting the front sole hold-down device is separated. Thereby can determine the relative position of the carrier articulation point with respect to the position of the Sole hold-downs are fixed on the ski during assembly of the binding.

It is further preferred that the front sole retainer is firm and complete is arranged pivotably on the toe piece. This makes one special simple and stable construction of the toe together with the front Sole hold-down enables by the toe together with the Sole hold-down e.g. can be formed in one piece. Alternatively, the front sole retainer can also be swung out laterally with respect to the The toe should be designed to trigger a sideways function To ensure safety ski binding.

According to a preferred embodiment of the invention, the carrier is as Articulated chain with rigid support parts, which are interconnected by means of swivel joints are connected, which are each one transverse to the longitudinal direction of the ski and parallel to the The top or bottom of the ski is pivotable. This will supports the flexing of the flexible sole of a Telemark ski boot. A binding designed in this way, in contrast to conventional ones Telemark bindings with a cable pull have the advantage that they are torsional and is torsionally rigid against corrosion and / or rotational movements around axes of rotation not parallel to the swivel axes of the swivel joints. This will make the Steerability of the ski considerably with the heel lifted off the top of the ski improved. In the case of a binding according to this embodiment, the Invention on the holding part, a first support part around a first, transverse to the longitudinal direction of the ski and pivoted articulated parallel to the top of the ski, and on first support part pivotable about a second axis of rotation parallel to the first articulated second support part, on which the buttocks is arranged. The first Rotation axis can be about 1/8 of the distance between the front and the rear Sole retainer and the second axis of rotation about 1/3 of this distance from the tip of the foot be offset towards the heel.

As an alternative to designing the carrier as an articulated chain, the carrier or at least part of the carrier also made of a flexible material, e.g. from one elastic plastic plate, designed to deflect the flexible Support the sole of a Telemark ski boot.

When telemark skiing, the length of the shoe sole changes as a result of different deflection of the sole of the shoe as a function of lifting the heel from the top of the ski. Accordingly, the binding needs to be adjusted to this Shoe sole length changes the distance between the front and the rear Sole hold-downs can be changed. According to a preferred embodiment of the To this end, the invention is the buttocks in the longitudinal direction of the shoe is slidably arranged on the carrier that it is in the sense of an enlargement of the Distance between the front and rear cheeks against the force of a spring is movable. It is further preferred that with a minimal shoe sole length the buttock is still pressed against the shoe by the spring ensure a play-free shoe holder in the binding. As an alternative to the carrier can also be arranged in a longitudinally displaceable manner on the buttock be adjustable even in the longitudinal direction of the beam, e.g. two carrier parts longitudinally connected to each other and held together by a spring become.

According to a further preferred embodiment of the invention, the rear one Sole holding-down device can be swung out laterally with respect to the buttock is to the function of the sideways release of a safety ski binding guarantee. For the sideways release, the buttocks can be used with a Trigger device may be provided, which is essentially a sideways trigger device on the front jaw of a common safety ski binding corresponds. In particular, the buttocks can for this purpose with on the side Sole hold-down devices provided with rollers that can be rotated about vertical axes of rotation to support sideways release. Further can be used as a requirement for the The sole of the shoe is provided with a sliding plate that can be swung out to the side to be essentially independent of the friction of the shoe sole To ensure sideways release.

The telemark ski binding according to the invention is preferably with a ski brake provided that a braking element and an articulated to this tread plate includes. The braking element is articulated on a holding part which can be fixedly attached to the ski, this braking element holding part preferably as an integral part of the Toe is formed. The tread plate is designed and in The front cheeks are arranged so that they are integrated into the ski boot in the area The tip of the shoe is exerted on the tread plate, the downward relative to the ski and / or is directed forward, the braking element in a non-braking position holds up. This arrangement ensures that the ski brake on the one hand is held up in the non-braking position even when the heel is off, as long as the tip of the ski shoe has a downward or forward force on the Tread plate, and on the other hand when the ski boot is separated from the binding comes into operation to brake the ski, even when the ski boot is in a binding position with the shoe heel lifted off the binding. In contrast, common ski brakes use ski bindings for the alpine Skiing the braking element only by a downward force on the Tread plate held up, the tread plate usually in the area of Buttock is arranged.

To further improve the safety of holding the braking element the tread plate can be provided with a locking device which is designed in this way and is arranged on the tread plate so that it is in the position for Holding up the brake element locks as long as the ski boot is in relation to the Skis exerts downward force on the tread plate. This ensures that the ski brake only when the step plate is completely relieved by the Ski boot jumps into its braking position. In this way unwanted braking can be done the ski brake can be prevented.

According to a further preferred variant of the invention, the buttock is included Provide downwardly projecting supports, which are in a binding position with lowered heel over a suitably trained, firm on the top of the ski attached bead to grip the buttocks against lateral in this position To fix shifts. This allows the ski to be steered in one Binding position can be further improved with the heel of the shoe lowered.

The following detailed description of the present invention serves in conjunction with the accompanying drawings only as an example for a better understanding of the invention and is not intended to limit the scope of the claims to grasp. For the person skilled in the art from the following description in Connection with the accompanying drawings and the entirety of the claims further advantageous embodiments and combinations of features without further ado recognizable, but still within the scope of the present invention lie.

The one-piece toe piece 60 has a fixedly attachable to a ski essentially plate-shaped base section 62. At the front end is the integrally formed upwardly extending and forwardly curved front wall 64. On the side of this front wall facing the shoe is the front Sole holder 66 is formed, which has the shape of a bead. In one in The bulge-shaped front has a plane essentially parallel to the top of the ski Sole retainer 66 has an arcuate plan, which the corresponds to the average outer shape of a ski boot tip. The shoe facing side of the front wall 64 of the toe is similar arched, with the ground plan of the average outer shape of the The tip of a ski boot sole conforms to standard 75.

The base portion 62 of the toe 60 is with a first continuous, transverse to Provide the longitudinal direction of the ski and a bore parallel to the top of the ski. This is designed to receive the first hinge axis 2, on which the first Carrier part 10 is articulated. The location of the base section 62 with this hole forms thus a holding part to hold the carrier described below on the ski. The first hinge axis 2 is about 1/8 of the distance between the front 66 and the rear sole retainer 40.1, 40.2, 40.3 from that for the foremost sole tip intended location on the toe 60 to the heel.

On the base part 62 of the front jaw 60 there are also two lateral support walls 68 molded, each with a bore for receiving and pivoting storage of a brake element 90 for the ski brake described in more detail below are provided. The two support walls 68 with the holes form one Brake element holding part to hold the brake element 90 on the ski. The two Bores are essentially parallel to the first hinge axis 2 and to one another arranged in alignment and essentially define a to the first hinge axis 2 parallel first axis of rotation 6, around which the braking element 90 is pivotable the two support walls 68 is articulated. The two support walls 68 extend laterally on the base portion 62 of the toe piece 60 approximately from the position of the first hinge axis 2 to the rear.

The first carrier part 10 is essentially U-shaped with two legs 11, 12 and a web 13 connecting the two legs 11, 12. The two Legs 11, 12 each have one at their leg ends remote from the web 13 Bore, which are designed to receive the first hinge axis 2, around the to articulate the first carrier part 10 on the front jaw 60. On its jetty side Longitudinal end is the first support part 10 with one to the two holes in the Legs 11, 12 provided substantially parallel bore for receiving a second hinge axis 8 is formed, on which the second carrier part 14 is articulated. The second hinge axis 8 is about 1/3 of the distance between the front 66 and the rear sole retainer 40.1, 40.2, 40.3 from the for the The foremost sole point provided on the toe piece 60 back to the heel staggered.

Essentially between the two legs 11, 12 of the first carrier part 10 and A step plate 80 for the ski brake is located above the base part 62 of the toe piece 60 arranged. The tread plate 80 of the binding shown in Figures 1 to 5 corresponds essentially to the tread plate 180 shown in FIG. 6, which is the latter only distinguished from the former by an additional locking lever 188. The Step plate 80 has an elongated floor plan and extends in the longitudinal direction forward beyond the position of the front sole retainer 66, into the bulge formed by the front wall 64 of the toe piece. As a stop for the front edge of the ski boot sole is on the tread 80 near its front edge approximately at a right angle to the base upwards extending wall 82 integrally formed. This wall 82 also serves as the tread plate 80 in its front region in that through the front wall 64 of the front jaw 60 formed curvature longitudinally and around a parallel to the top of the ski to hold the transverse axis pivotably by behind one correspondingly integrally formed on the front jaw wall 64 projection 67.

In its lowered position shown in Figures 1 to 3, in which it Brake element 90 holds up for the ski brake in a non-braking position the footplate 80 on appropriately designed supports of the base section 62 of the Front jaw 60 and then forms together with the first carrier part 10 in essential flat contact surface for the ski boot sole in its toe and Bale area.

At its longitudinal end near the web 13 of the first carrier part 10 the base of the tread plate 80 is an angled downward thereon wall-shaped extension 84 formed. This extension 84 is at its lower end provided with a through hole which for receiving the web 91 of the im essential U-shaped brake element 90 is formed for the ski brake. The The bore runs essentially parallel to the two hinge axes 2, 8 on the first Carrier part 10 and defines a second axis of rotation 4, around which the Brake element is pivotally articulated on the tread plate 80.

The braking element 90 is made of a spring steel wire with a circular cross section manufactured and has a substantially U-shaped shape two legs and the this connecting web 91 on, as described above in the bore in the extension 84 of the tread plate 80 is mounted. The two run from the connecting bridge 91 Leg on a first section 92, 93 initially substantially perpendicular to Connecting web 91, then on a second section 94, 95 approximately parallel to Connecting web 91 such that the two legs diverge, and then on a third section 96, 97 again approximately parallel to first section. On its second section 94, 95, the two legs are each through one of the bores described above in the two support walls 68 of the Base portion 62 of the front shoe 60 passed through, so the braking element 90th about the first axis of rotation 6 pivotable on the two support walls 68. The third gates 96, 97 of the two legs serve as actual brake legs 96, 97 the ski brake, which reach into the snow to brake the ski.

In Fig. 4 is the movement path of the to clarify the movement Step plate 80 with the second rotating joint 4 connecting the braking element 90 a double arrow 9 shown. The braking element 90 is about the Front jaw 60 fixed first swivel 6 swiveling. This will make the second Swivel 4 moves on a circular path while the tread plate 80 at its front Longitudinal end performs a swivel movement combined with a longitudinal displacement.

Between the tread plate 80 and the brake element 90 there is a helical spring two legs arranged so that the ski brake if the tread plate 80 is not is held down by the ski boot, automatically into that shown in Fig.4 brings braking position. In this position, the tread plate 80 is upward from Base part 62 is raised and the two legs of the braking element 90 are standing beyond the bottom of the ski to brake the ski. As soon as the tread plate 80 is loaded by the ski boot, it becomes against the spring force of the Coil spring moved down and forward. The second axis of rotation 4 and thus the web 91 of the braking element 90 on the in FIG Double arrow 9 shown circular path moves down, while at the same time by the Swiveling movement of the braking element 90 around the first, fixed to the front shoe 60 arranged axis of rotation 6, the protruding legs 96, 97 of the brake element 90 be swung up. To hold down the step plate 80 and thus to Holding the braking element 90 upwards is a relatively small amount downwards and / or forward force of the ski boot on the tread plate 80.

This means that the force required to hold down the step plate is exerted by the ski boot the step plate is to be exercised, can still be reduced, is in the in Fig. 6 illustrated embodiment of the invention on the tread plate 180 further rocker-shaped locking lever 188 on the base of the tread plate 180 articulated. One arm of the locking lever 188 is a locking hook formed while the other arm of the rocker-shaped locking lever 188 serves as an operating arm. Is the tread plate 180 in the lowered position Actuating arm of the locking lever 188 loaded by the ski boot sole, see above is thereby the locking hook by a corresponding to the base of the Trained cam hooked toe. This means that even with one extremely little force on the tread plate 180 or the actuating arm of the Locking lever 188 prevents any lowering of the braking element, which may could lead to unwanted braking of the ski.

The second carrier part 14 is essentially a flat hollow profile carrier with two lateral hollow profiles 15, 16 and a connecting plate 17 connecting them trained, which is provided with recesses to save weight. On the front A fork-shaped front section 18 is integrally formed on the longitudinal end of the second carrier part 14. The two fork tips at the front end of the second carrier part 14 are each with one Provide bore, which are designed to receive the second hinge axis 8 to to articulate the second carrier part 14 on the first carrier part 10. At his the fork-shaped front section 18 opposite longitudinal end carries the second Carrier part 14 the buttocks 20th

The rear jaw 20 has an L-shaped base part, one leg 22 of which second carrier part 14 is traversed in the longitudinal direction in a displacement guide the buttocks 20 slidably in the longitudinal direction with the second carrier part 14 connect. Inside this leg 22 there are two compression springs (not shown) arranged, which biases the base part of the buttock 20 in one Hold the target position on the second carrier part 14. The base part and therefore the whole Buttocks 20 are against the force of the compression springs with respect to the second Carrier part 14 slidable to the rear. In the illustrated in Figures 1 to 5 The embodiment of the invention is the rear jaw 20 in this way by up to 30 mm Longitudinally displaceable with respect to the second carrier part in order to adapt the Distance between the front sole holder 66 and the rear Sole retainer 40.1, 40.2, 40.3 to a change in the length of the shoe sole due to To ensure deflection of the shoe sole.

On the other leg 24 projecting from the second carrier part 14 A cheek structure part 30 is arranged behind the cheek base part. On the shoe facing side of the jaw structural part 30 is the rear sole hold-down device 40.1, 40.2, 40.3 molded. The rear sole hold-down device 40.1, 40.2, 40.3 has the shape of a bead. In the binding position with the heel of the shoe lowered, it points in an arcuate plane essentially parallel to the top of the ski Floor plan of which is the average exterior shape of a ski shoe heel corresponds. The side of the shoe structure part 30 facing the shoe is analog Formed arcuate. In the illustration of Figure 5, the hatched A section through the middle of the buttock where the Arch shape of the rear sole retainer 40.2 and the side facing the shoe of the jaw structural part 30 extends farthest to the rear. In solid lines is the outline shape of this side and the rear sole holder 40.3 drawn on one side edge, where it is the most distant due to the arch shape reach in front. The buttock 20 is also shown in an analogous manner in FIG. 4.

The jaw structural part 30 is laterally about a central pivot axis 32 can be swung out on the upstanding leg 24 of the base part of the buttock 20 stored, the jaw structural part 30 by a resilient Release device in its target swivel position on the base part of the jaw for fixing of the ski boot is held in order to trigger the safety of the side To provide ski binding. The trigger device corresponds essentially to that Lateral release device on the front jaw of a common one Safety ski binding.

To support the sideways release on both sides of the buttocks, below the side edges of the rear sole hold-down device 40.1, 40.2, 40.3 in itself a roller 48 rotatable about a vertical axis of rotation is arranged in a known manner. Next is also in a known manner as a support for the shoe sole in Heel area a laterally swingable sliding plate 46 on the second Carrier part 14 arranged leg 22 of the buttock base part arranged to one essentially independent of the friction of the shoe sole To ensure sideways release.

To create a shoe guiding device, which when entering and when Get out of the binding the back edge of the shoe sole around the back Sole retainer 40.1, 40.2, 40.3 leads around, is on the structural part 30 of the Buttock 20 continues a one-piece rocker about a substantially horizontal Transverse axis 52 pivoted. The seesaw comprises two roughly parallel guide arms 54, 56 and arranged perpendicular to one another and perpendicular to the transverse axis 52 an actuating arm 58 which extends from the transverse axis 52 essentially into the extends in the opposite direction with respect to the guide arms 54, 56.

The transverse axis 52 is approximately at the same height with respect to the second carrier part Structural part 30 of the rear jaw 20 arranged like the bulge-shaped rear Sole hold-down 40.1, 40.2, 40.3. As a result, the length of the guide arms 54, 56 minimal, which is required to the shoe sole on a circular path around the rear To hold sole hold-downs 40.1, 40.2, 40.3 around.

The guide arms 54, 56 extend through two from the transverse axis 52 slot-shaped passages 34, 36 in the structural part 30 and in the rear sole hold-down 40.1, 40.2, 40.3, which are each off-center between the middle and the Side edges are formed in the structural part 30 and extend in the longitudinal direction. By the two slit-shaped passages 34, 36 becomes the bead-shaped rear one Sole retainer 40.1, 40.2, 40.3 divided into three parts. The length of the Guide arms 54, 56 are sized to be near the rear Sole holding-down device 40.1, 40.2, 40.3 through the slot-shaped passages 34, 36 through each over the shoe-side edge of the rear sole hold-down 40.1, 40.2, 40.3 protrude beyond. This will turn off when getting on and off the binding of the sole protrusion on the heel-side shoe end by the two Guide arms 54, 56 essentially on a circular path with the transverse axis 52 as Center around the rear sole hold down 40.1, 40.2, 40.3 around, the both guide arms 54, 56 touch the shoe sole off-center.

In the sides of the two guide arms 54, 56 pointing towards the shoe sole an angular recess 57 is formed around the lower edge of the shoe sole to record. As a result, when entering and exiting the binding, when the guide arms 54, 56 touch the sole of the shoe, this on two sides of the Lower edge held by the guide arms 54, 56 to ensure safe guidance of the Ensure shoe sole.

Above the transverse axis 52 is in the two slot-shaped passages 34, 36 each a cylindrical coil spring 44 is arranged with two legs. By at two springs 44 one leg on the jaw structure part 30 and the other on one Knobs 45 is supported on a side surface of the slot-shaped Passage 34, 36 extending guide arm 54, 56 is attached, act the two springs 44 between the jaw structure part 30 and the rocker. The spring legs supported on the knobs 45 can slide freely on them and the springs 44 and the knobs 45 are such with respect to the transverse axis 52 arranged that their lines of action in a first pivoting position of the rocker one side and in a second swivel position on the other side on the Transverse axis 52 pass. This arrangement makes it bistable Rocker switch for the rocker created to the rocker in the manner of a mechanical flip-flops between two stable swivel positions on the transverse axis 52 switch back and forth. When the rocker is actuated from one to the other stable pivot position, this is moved over a dead center, in which the Lines of action of the springs 44 run through the transverse axis 52.

The first stable pivot position of the rocker shown in FIG. 5 defines the Open position of the rear binding jaw 20 or the binding. In the open position are the two guide arms 54, 56 upwards and the actuating arm 58 behind directed below. In this position the shoe heel can be used to get into the binding placed on the guide arms 54, 56 and then pressed down without manipulation by hand. This will make one so-called step-in function provided.

The second stable pivot position of the rocker shown in Figures 1, 2, 3 and 4 defines the closed position of the rear binding jaw 20 or the binding. In the closed position are the two guide arms 54, 56 down and the Actuating arm 58 directed upwards. In this position, the second Carrier part 14 held by the rear sole hold-down 40.1, 40.2, 40.3 Shoe sole touched by neither of the two guide arms 54, 56. This will ensures that in the closed position the guide arms 54, 56 neither the Retaining function of the rear sole retainer 40.1, 40.2, 40.3 still the Impede the safety function of the side release device.

On the leg 22 of the buttock base part arranged on the second carrier part 14 is a wall-shaped, downward-facing support on both long sides 26 integrally formed, which in a binding position with a lowered heel over a appropriately designed longitudinal bead 28 firmly attached to the top of the ski to grab. This causes the buttocks to be in the binding position with the heel lowered 20 fixed against lateral displacements, making the ski steerable in this Binding position is further improved.

3 shows the binding of the heel raised from the top of the ski. Out this representation is clearly recognizable, as with the heel raised by the Base section 62 of the front jaw 60, the tread plate 80, the first carrier part 10 and the second carrier part 14 creates a support for the ski boot sole, which due to the pivotability of the two pivots 2, 8 between the first Support part 10 and the front jaw 60 on the one hand and the first support part 10 and the second support part 14, on the other hand, essentially arcuate in the longitudinal direction is designed to deflect the sole of a telemark ski boot in Longitudinal support.

To get into the binding, if necessary, first insert it into your Open position brought either by hand or by means of a ski pole Actuating arm 58 is pressed down. Then the toe is in the Front cheeks 60 inserted by the sole protrusion at the toe under the front sole hold-down device 66 is pushed on the toe piece 60. This will the tread plate 80 on the toe piece 60 is depressed and thus the ski brake lifted up. The shoe heel is then placed on the guide arms 54, 56 on Buttocks 20 placed such that the bottom edge of the shoe sole through the two angles 57 is received in the guide arms 54, 56. Now the Shoe heel pressed down, being guided by the guide arms 54, 56 becomes. When the heel of the shoe is pressed down, the buttock 20 is pressed by the two Guide arms 54, 56 initially against the force of the compression springs in the base part of the Buttocks 20 in the longitudinal direction to the rear, moved away from the shoe until the two guide arms 54, 56 run substantially parallel to the second carrier part. As the heel of the shoe is pressed down further, the buttock 20 is replaced by the Compression springs in its base part pushed forward again towards the shoe, the rear sole hold-down device 40.1, 40.2, 40.3 over the heel-side sole projection the sole of the shoe is pushed. After the shoe heel except for the second Carrier part 14 or the base part of the buttock 20 is lowered and the shoe thus fully inserted in the binding, the seesaw is supported by the two Coil springs 44 of the toggle switch a little further in the Entry direction moves until the closing position of the binding is reached, in which the shoe sole is no longer touched by guide arms 54, 56.

To get out of the binding, e.g. the actuating arm by means of a ski pole 58 pressed down. As a result, the two guide arms 54, 56 are first moved forward and upward such that the two angles 57 of the Guide arms 54, 56 embrace the lower edge of the shoe sole. Another one Pressing down the actuating arm 58 becomes the heel side Shoe sole protrusion moved forward and upward around the rear To hold sole hold-downs 40.1, 40.2, 40.3 around. Since the tip of the shoe through the Front jaw 60 is held immovably, the rear jaw is simultaneously 20 by the two guide arms 54, 56 initially against the force of Compression springs in the base part of the rear jaw 20 in the longitudinal direction to the rear, from Shoe moved away until the two guide arms 54, 56 are substantially parallel run to the second support part. Then when lifting the Heel the two guide arms 54, 56 pivoted further up and Buttocks 20 back through the compression springs in its base part to Press the shoe down until the binding is in the open position. In the The rocker is open position by the two coil springs 44 Toggle switch in the swivel position with the upward Guide arms 54, 56 held so that for a subsequent entry into the No manipulation by hand is required and therefore the step-in function is guaranteed. After removing the toe from the toe 60 the ski brake automatically in its through the coil spring in the ski brake Brake position brought.

In summary, it can be stated that the invention is a telemark ski binding is provided which the cable pulls of previous Telemark ski bindings overcomes related disadvantages.
