Description

The invention relates to a ski binding, in a first arrangement in which a front end of a ski shoe is held in a first holding device, for an ascent with the ski and in a second arrangement in which the front end of the ski shoe is held in a second holding device can be used for alpine skiing. The second holding device can be releasably connected to the first holding device.

Freetouring is a popular sport today, in which the effort of ascending with the ski is ideally combined with the enjoyment of the subsequent descent in untouched terrain. In order to be able to carry out the ascent and descent safely, more and more bindings are being offered that try to strike a balance between as little weight as possible for the ascent with the necessary security for the descent in deep snow.

So is from the EP 2 826 528 B1 a combined touring and alpine binding is known, with a first holding device in which a front end of the ski shoe is held for an ascent and a second holding device in which the front end of the ski shoe is held for a descent. The lateral engagement elements of the first holding device necessary for the ascent are arranged directly on the second holding device. The configuration between ascent and descent can be varied by pivoting the second holding device. Particularly in the configuration for the ascent, the weight of the integrated second holding device makes the ascent unnecessarily difficult.

There is therefore a need for a generic ski binding that does not have these disadvantages. It is a task of the registration to provide a ski binding that can be used to safely ascend and descend.

This object is achieved by the ski binding with the features of claim 1. Advantageous further developments of the ski binding are given in the dependent claims and in the description.

One aspect of the invention relates to a ski binding with a front jaw for holding a front sole end of a ski shoe, and with a rear jaw for holding a rear sole end of a ski shoe. With the ski boot held in the ski binding, the front end of the sole is arranged in the direction of skiing in front of the rear end of the sole and points in the direction of the tip of the ski.

The toe of the ski binding comprises a base with which the toe can be connected to a ski and a jaw body which is connected to the base, or is formed together with the base, for example is formed in one piece with the base .

The toe comprises a first holding device with which a ski boot at the front end of the ski boot can be connected to the ski for ascent. This first holding device defines an articulation axis about which the front end of the ski boot can be pivoted. The toe also includes a second retainer that connects the ski boot to the ski at the front end of the ski boot for downhill skiing, the second retainer having a first downhill configuration in which the second retainer contacts the front sole end of the ski boot and has a second configuration for the ascent in which the second holding device is out of contact with the front sole end of the ski boot. In the first configuration for the descent, the second holding device is coupled to the base and / or the first holding device, in the second configuration for the ascent the second holding device can be removed completely, in particular in part, from the first holding device. This means that the second holding device is designed such that it can preferably be removed in one piece from the base and / or the first holding device for an ascent with the ski, and can preferably be accepted manually. However, manual removal is described here essentially without the use of a tool, but for example with the help of a ski pole.

The first holding device preferably comprises at least a first, preferably a first and a second engagement element, which can be moved from a first position in which they are at a first distance from one another to a second position in which they are at a second distance from one another that is smaller than the first distance. The at least one first engagement element or the first engagement element engages in the second position in a first receptacle of the front sole end. The first shot can preferably be formed in a side wall of the front sole end, which runs essentially parallel to a longitudinal axis of the ski boot. In the second position, the second engagement element engages in a second receptacle of the front sole end, the second receptacle being formed with respect to a central axis of the ski boot in the longitudinal direction with respect to the first receptacle. The first engaging element, the first receptacle, the second engaging element and the second receptacle thus define the joint axis about which the ski boot can be pivoted.

The front jaw may further comprise a tensioning device that can move the first engagement element and the second engagement element into the second position and hold and / or secure it in the second position. The tensioning device can comprise a tensioning lever with which the tensioning device or a tensioning element of the tensioning device can be tensioned and relaxed or released, preferably manually or with the aid of a ski pole. If the tensioning device is tensioned, the tensioning lever is accordingly in a second position, in the relaxed or released state in a first position.

The first holding device can be a holding device, such as is used, for example, in a toe of a pin binding, with pins as engagement elements which engage in the corresponding receptacles in the ski boot sole.

The second holding device can have a holding device body with a first ski shoe holder, which at least laterally encompasses the front sole end, and a second ski shoe holder, which at least laterally encompasses the front end of the ski shoe sole. The first ski shoe holder and the second ski shoe holder can form support surfaces which, in the first configuration for the downhill skiing, rest on a free surface of the front sole end of the ski shoe sole and hold the ski shoe on the ski. The first ski shoe holder can be connected to the holding device body in a first ski shoe holder swivel joint and the second ski shoe holder can be connected to the holding device body in a second ski shoe holder swivel joint, with a swivel axis of the first ski shoe holder swivel joint and a swivel axis of the second ski shoe holder swivel joint essentially perpendicular to the joint axis of the first holding device and perpendicular to one Ski surface stand. As the pivot axis of the first ski boot holder pivot joint and the pivot axis of the second Ski shoe holder swivel joint can serve a wire that is bent essentially in a U-shape. The wire can be inserted through openings in the top of the holder body, the two open ends of the wire engaging in or through an opening of the first shoe holder and the second shoe holder corresponding to this opening to form the ski shoe holder pivot joints.

In general, it should apply that the parts forming a joint can have sliding surfaces that are formed by subsequent machining or by tools. Only one of the parts forming the joint can have the sliding surface or both parts forming the joint. The sliding surfaces can also be formed by separate parts, such as annular bodies, which are connected to a joint part during manufacture or afterwards. Finally, it should also not be excluded that a joint comprises a bearing, such as a ball, needle or barrel bearing, etc., which is then shielded from the outside in order to reduce the risk of contamination by the snow.

A spring element can clamp the first ski shoe holder and the second ski shoe holder together and press against the sides of the front sole end when the ski binding is used for the downhill run.

Finally, the second holding device can comprise a connecting device which releasably, preferably manually releasably, connects the second holding device to the base, to the jaw body and / or to the first holding device.

The connecting device may comprise a first connecting arm which is rigidly connected to the holding device body or formed by the holding device body, and a second connecting arm which is rigidly connected to the holding device body or formed by the holding device body.

The first connecting arm and the second connecting arm can be arranged in parallel or essentially parallel next to one another and at a distance from one another. The first and second connecting arms can protrude from the holding device in the direction of skiing.

The first connecting arm and the second connecting arm can each have a free end. The connecting arms can have an engagement structure at the free ends, with which the connecting arms can cooperate with a counter-engagement structure, which is formed on the jaw body or the base or is encompassed by the jaw body or the base, in order to form a pivot joint in which the second holding device is movably mounted on the base or on the jaw body is. The engagement structure with the counter-engagement structure can preferably be manually connected and the engagement structure can be separated from the engagement with the counter-engagement structure, preferably manually, so that, as already described above, the second holding device is designed to be removable from the front jaw manually or by hand. The engagement structure can be designed in such a way that it can be connected to the counter-engagement structure in a positive and / or non-positive manner. The counter-engagement structure can be, for example, a round bar, onto which the engagement structure can preferably be clicked on manually. The engagement structure and the counter-engagement structure preferably form a connecting arm pivot joint, or respectively two connecting arm pivot joints, in which the second holding device can be pivoted relative to the base. The round rod, or a rod with a polygonal, oval or other shaped circumference, can be firmly connected to the base or rotatably mounted in the base.

The second holding device has at least one receiving opening into which a securing element for fixing the second holding device in the first configuration for the descent with the ski can engage. The holding opening is preferably formed in one side of the second holding device, which extends essentially parallel to the longitudinal axis of the ski. The receiving opening can be arranged in the skiing direction in front of the stop for the front sole end of the holding device body and / or in front of the first and the second ski shoe holder.

The securing element is, in particular, at least one or the engaging element of the first holding device, which can be tensioned by means of the tensioning lever, engages in the receiving opening and secures the second holding device in the first configuration for the descent with the ski. If the first holding device is a pin binding, the second holding element can have exactly two receiving openings into which the pins can engage. The receiving openings on the second holding device are arranged in such a way that, in the first configuration, they lie in the same relative position to one another as the receptacles for the pins of a ski shoe sole, which is prepared to be held in a pin binding.

The second holding device may further comprise a securing device which is pivotally connected to the holding device body in at least one securing device swivel joint and fixes the second holding device in the second configuration. The at least one securing device swivel joint defines an articulation axis that runs essentially parallel to the connecting arm swivel joint described above. To form the securing device swivel joint, the connecting arm can have an opening into which an axle element connected to the securing device or formed by the securing device engages, or an opening can be formed in the securing device into which an axle element connected to the connecting arm or formed by the connecting arm engages . The securing element, when connected to the holding device body, is preferably arranged in a space between the first connecting arm and the second connecting arm. That is to say, the two connecting arms are essentially parallel to one another and are spaced apart from one another, each of the connecting arms comprising a connecting arm outer side and a connecting arm inner side, and the two connecting arm inner sides facing one another. The space is thus a space which is defined by a width of the inner side of the connecting arm perpendicular to their longitudinal axis and their distance from one another and a length of the connecting arm. The securing element can protrude from the room in a pivoted position with a front or rear end in the direction of skiing.

The securing device can comprise at least one securing arm, preferably the securing device comprises a first securing arm, a second securing arm and a securing plate which connects the first securing arm and the second securing arm to one another at one end. The securing element can be essentially U-shaped, with the securing plate as the base. The securing arms protrude essentially vertically from the base and taper continuously or continuously and / or in stages or sections from the base to the respective free end. The securing device is preferably formed in one piece, for example bent from a metal sheet or created in a casting process.

The free ends of the securing arms can be hook-shaped and, in order to secure the second holding device with the hook-shaped ends, which each form an engagement, engage under the connecting arm pivot axis, so as to prevent The, for example, claw-shaped engagement structure of the free ends of the connecting arms can automatically disengage from the connection with the counter-engagement elements if the ski is subjected to hard impacts during descent, for example.

The at least one securing arm or the first securing arm and / or the second securing arm can furthermore have a projection which projects essentially at a right angle from the corresponding securing arm. The projection projects from the side of the securing arm, which, when the securing device is connected to the connecting arm or the connecting arms of the second holding device, faces the connecting arm. The molding can extend beyond the connecting arm, so that the deformation rests on the connecting arm when the second holding device is secured by means of the securing element.

The toe may also include a locking mechanism that locks the tensioner when the second retainer is in the first ski descent configuration. The locking body comprises at least one locking body, which forms a contact surface for the front end of the ski boot sole, and a spring element, which prestresses the locking body in a release position.

When entering the binding with the ski boot in the first configuration, the front end of the sole comes into contact with the contact surface of the locking body and moves the locking body into a locking position against a force of the spring element into the holding device body of the second holding device. The locking body is held in the locking position as long as the ski boot is held in the first configuration set for downhill skiing. If the ski boot is removed from the binding or the binding is moved from the first configuration into the second configuration, the locking body is automatically moved back into the release position by the force of the spring element, the spring element moving with a first axial end on the holding device body and with can support a second axial end on the locking body. The spring element can be a compression spring, a tension spring, a leaf spring, an elastically deformable solid body, a gas or liquid piston or another spring element.

The locking body may include a nose protruding perpendicular to the longitudinal direction of the ski, which acts on the tensioning device of the first holding device in order to secure the tensioning device in the second position by preventing the tensioning device from being released as long as the ski binding is in the first configuration and a ski boot is held in the ski binding. In order to secure the tensioning device in the tensioned position, the nose can, for example, engage in the tensioning device, rest on the top or bottom of the tensioning device, at least partially embrace the tensioning device, etc.

The toe piece can further comprise a support plate for a front part of the ski shoe, on which a front area of the ski shoe sole rests when the ski shoe is in the binding. The support plate can have a surface that is prepared so that the ski boot sole can be released from the toe without great friction, for example when the ski binding or the toe piece is released. The support plate can be movable transversely to the direction of skiing in order to give the ski boot freedom of movement transversely to the direction of skiing before and during a side release. Such contact plates are known in the prior art, which is why a detailed description is unnecessary.

The contact plate can be adjusted to a first position and a second position with a tool via an adjustment mechanism. In the first position, the support plate is arranged relative to the toe so that the binding with a ski boot with a standardized classic alpine sole can be used. In the second position of the support plate, the binding can be used for the ascent and descent with a ski boot with a standardized touring sole.

A second aspect of the invention relates to a second holding device as described on the previous pages. The second holding device is prepared to be connected to the above-described first holding device.

The connection of the articulation axis A2 with the engagement structure 45a then forms a swivel joint S2, the articulation axis A3 with the engagement structure 46a a swivel joint S3. Since the articulated axes A2 and A3 have a common pivot axis S23 ( Figure 1 ) for the second holding device 4, the second holding device 4 can be pivoted about this common pivot axis S23 relative to the first holding device 3, in particular pivoted to the first holding device 3 and pivoted away from the first holding device 3.

A securing device 6 is connected to the connecting arms 45, 46. The securing device 6 comprises a first securing arm 61 and a second securing arm 62 and a securing plate 63 which connects the first securing arm 61 and the second securing arm 62 at one end, so that the securing device 6 essentially has a U shape. The closed end of the U faces the holder body 41, the open ends, which form an engagement 61a, 62a of the first securing arm 61 and the second securing arm 62, are hook-shaped. The securing device 6 and the holding device body 41 are pivotally connected to one another. For this purpose, the first connecting arm 45 has a through opening 45b and the first securing arm 61 has a through opening which is not visible. A hinge axis A4, which also forms a swivel joint S4, extends through the two through openings 45b. The second connecting arm 46 has a through-opening which cannot be seen, the second securing arm 62 has a through-opening 62b which are penetrated by a joint axis A5 in order to form a swivel joint S5. The swivel joint S4 and the swivel joint S5 form a common swivel axis S45, about which the securing device 6 can be swiveled relative to the holding device body 41. In the exemplary embodiment, the securing device 6 is arranged between the first connecting arm 45 and the second connecting arm 46.

The pivot axis S45 is arranged between the pivot axis S23 and the securing plate 63, in the exemplary embodiment closer to the securing plate 63.

If the second holding device 4 is pivoted completely to the first holding device 3, the securing device 6 secures the second holding device 4 in this position by the interventions 61a, 62a of the securing arms 61, 62 under the articulated axes A2, A3 ( Figure 1 ) grip and thus prevent the engaging structure 45a, 46a of the connecting arms 45, 46, which is claw-shaped in the exemplary embodiment, from being able to unintentionally detach itself from the articulated axes A2, A3, for example due to the action of impact forces when descending on uneven terrain.

The securing device 6, or respectively the first securing arm 61 and the second securing arm 62, further comprises formations 64, 65 which protrude from one of the side longitudinal sides of the first securing arm 61 and the second securing arm 62 at an angle of essentially 90 °. The projection 64 protrudes from the first securing arm 61 in the direction of the first connecting arm 45, and in the exemplary embodiment has a length transversely to the longitudinal axis L of the ski that is greater than a thickness of the first connecting arm 45. The same applies accordingly to the projection 65.

Finally, the first connecting arm 45 preferably comprises a counter-holding element, which cannot be seen in the view, and the second connecting arm 46 comprises a counter-holding element 46c, which is connected to the holding elements 91, 92 formed at the front end of the first holding device 3 in the skiing direction. Figure 1 ) can cooperate in order to secure the second holding device 4 in a position pivoted away from the first holding device 3, for example for an ascent.

The first ski shoe holder 43 is connected to the holding device body 41 in a swivel joint S0, the second ski shoe holder 44 is connected to the holding device body 41 in a swivel joint S1. A spring element 9 (see Figure 6 ) tensions the two ski shoe holders 43, 44 towards one another in a known manner, so that the two ski shoe holders 43, 44 are pressed laterally against the ski shoe sole with a toe piece 1, thereby gripping the ski shoe sole at a front end from above and / or laterally and thus secure the ski boot in the ski binding. The force of the spring element 9 can be set in a known manner and the set hardness of the binding can be read off in a window 10 in the holding device body 41. In the exemplary embodiment forms a U-shaped wire 93 the articulation axes for the swivel joint S0 and the swivel joint S1, the wire 93, respectively the two open ends of the wire 93, being inserted from above through openings in the holding device body 41 and through the ski shoe holders 43, 44. In the position in which the pivot axes for the ski boot holders 43, 44 form, the wire 93 is secured in the holding device body 41 against unwanted working out by form and / or non-positive connection.

The second holding device 4 further comprises a receptacle 47, in which the engaging element 31 of the first holding device 3 engages, and an invisible receptacle, in which the engaging element 32 of the first holding device 3 engages, when the front jaw 1 is used in alpine mode. By engaging the engaging elements 31, 32 in the receptacles 47, the second holding device 4 is secured against unwanted loosening. For this purpose, as when securing the first holding device 3, the first engagement element 31 and the second engagement element 32 are tensioned towards one another with the tensioning lever 5. This means that the receptacles 47, 48 in the toe piece 1 must be in the position for a descent in exactly the same position relative to the first holding device 3 in which the openings in the ski shoe sole for the pins 31, 32 are located when the Front cheeks 1 'of Figure 1 used for an ascent.

The Figure 3 shows a front jaw 1 with the first holding device 3 and the second holding device 4, which is pivoted away from the first holding device 3 but is connected to the first holding device 3. In this configuration, the front jaw 1 can be used for an ascent. So that the second holding device 4 does not inadvertently pivot onto the first holding device 3, the counter-holding elements 46c engage in the holding elements 91, 92 in order to detachably hold the second holding device 4 in the position shown and to secure it against unwanted loosening.

In this position you can see a contact surface 42a against which a front end of the ski boot sole rests when the ski boot is in the binding prepared for the descent ( Figure 4 ) is held, and a support surface 42 with which the ski shoe holder 44 rests on a free surface of a front end of the ski shoe sole when the ski shoe or its front end is held for departure in the second holding device 4.

The Figure 4 shows the toe 1 in a configuration in which the toe 1 is ready to receive a ski boot for a downhill run. The second holding device 4 is pivoted completely to the first holding device 3, the engagement elements 31, 32 of the first holding device 3 engage in the receptacles 47 on the second holding device 4, and thus secure the second holding device 4 in the position pivoted to the first holding device 3 against unwanted loosening.

The Figure 5 shows a section through the front jaw 1 of the Figure 4 along a binding center longitudinal axis BL. Here the spring element 9 can be seen for the first time that acts on the first ski shoe holder 43 and the second ski shoe holder 44 in order to press the ski shoe holders 43, 44 against the ski shoe sole. The holding element 92, which cooperates with the counter-holding element 46c, can also be clearly seen in order to secure the second holding device 4 in the position connected to the first holding device 3 and pivoted away from the first holding device 3. The sectional view also shows an adjusting element 12 with which the support plate 7 can be adjusted with the aid of a tool.

The Figure 6 shows a further section through the front jaw 1, wherein here the second holding device 4 is pivoted completely to the first holding device 3 and the engaging elements 31, 32 of the first holding device 3 engage in the receptacles 47 of the second holding device 4, which can be seen on the tensioned clamping device 5 is. The contact surface 42a, against which a ski boot held in the toe 1 with the front end of the ski sole rests, is clearly visible here. So that the engaging elements 31, 32 in the configuration for the departure do not unintentionally detach from the receptacles 47, 48, it is additionally necessary in the exemplary embodiment shown to engage the engaging elements 31, 32 by actuating the tensioning lever 51, i.e. moving the tensioning lever 51 away from the ski surface to lock in the second position.

The Figure 7 shows in a detailed view the safety device 5 shortly before closing or shortly after opening. The second holding device 4 encompasses the hinge axis A1, A2, and thereby connects the second holding device 4 to the first holding device 3 in a form-fitting manner. In order to prevent this form-fitting connection from being unintentionally released, the securing device 6 is now pressed in the direction of the arrow, so that the hook-shaped Free end 61a of the securing arm 61 partially engages or engages around the hinge axis A2 and thereby prevents the second holding device 4 from moving away from the Joint axis A2 can solve. To close the securing device 6, pressure is exerted on the molding 64 manually or, for example, by means of a ski pole tip. The procedure is reversed for releasing the securing device 6 before the second holding device 4 is separated from the first holding device 3.

Figure 8 shows the front jaw 1 with an additional locking element 8 ( Figure 9 ). The locking element 8 comprises a contact surface 83 for the front end of a ski boot sole, which in the exemplary embodiment is arranged centrally between the first ski sole holder 43 and the second ski sole holder 44. The contact surface 83 projects counter to the skiing direction in front of a contact surface 42a of the holding device body 41, so that the contact surface 83 of the locking element 8 comes into contact with the front end of the ski boot sole before it comes into contact with the contact surface 42a of the holder housing 41. The locking element 8 is movably mounted in the holding device body 41 of the second holding device 4, so that the locking element 8 can be moved into a locking position from a release position in the skiing direction into the holding device body 41.

The locking element 8 ensures that the engaging elements 31, 32 in the configuration for the departure do not unintentionally detach from the receptacles 47, 48 as long as there is a ski boot in the front jaw 1. This means that there is no additional locking of the engagement elements 31, 32 by actuation of the tensioning lever 51 in the configuration for the departure, as in the embodiment according to 1 to 7 explained, required and therefore cannot be forgotten by the user.

The Figure 9 shows the locking element 8 comprises a locking body 81, a nose 82 protruding from the locking body 81, the stop 83 and a surface 84 which serves as an abutment for a spring element 11, which prestresses the locking element 8 in the release position. The locking body 81, the lug 82, the stop 83 and the surface 84, which forms a stop surface for a spring element 11, which the locking element 8 in the in the Figure 9 shown relaxation position are formed in the embodiment as a single part, as in the Figure 9 , which shows a section through the front jaw 1 along the longitudinal axis BL of the jaw, can be clearly seen.

If a user climbs with a ski boot in the toe 1 Figure 8 , the front end of the ski boot sole of the ski boot first comes into contact with the stop 83 and displaces the locking element 8 in the direction of skiing. This will make the nose 82 moves into a position in which it locks the tensioning device 5, that is to say prevents the tensioning device 5 or the tensioning lever 51 from being able to be moved by hand or with the help of the ski pole, around the engagement elements 31, 32 of the first holding device 3 to move from the receptacles 47, 48 of the second receptacle 4. This state, in which the locking element 8 has been moved into a locking position against the force of the spring element 11, is shown in FIG Figure 10 pictured. The contact surface 83 of the locking element 8 and the contact surface 42a of the holding device body 41 are now in one plane, that is to say, flat to one another. The nose 82 rests on a surface of the tensioning element 52 or lies directly above a surface of the tensioning element 52 facing it, so that the tensioning device 5 cannot be released.

The Figures 11 and 12th show another toe 1 '''with an alternative solution, how the second holding device 4 can be connected to the base 2 in such a way that it can be pivoted relative to the first holding device 3 in the longitudinal direction of the ski in order to switch from a touring mode of the ski binding into a downhill mode switch. Two splint pins 200, which are connected captively to the base 2 and from which in FIG Figure 11 shown first position, in which they pivotally connect the second holding element 4 to the base 2, in which in the Figure 12 shown second position can be moved, in which the second holding device 4 can be removed from the base 2, for example to reduce the weight of the ski for the ascent in touring mode. The split pins 200 are preferably moved into the first and the second position by hand, less preferably with the aid of a tool. Each of the two split pins 100 has a snap ring 201, which secures it in the base 2 so that the split pin 200 does not accidentally fall out of the guide in the base 2. The movement of the split pin 200 can be a simple linear movement, or a rotary movement, such as a screwing movement, or a combined movement, in which the split pin 200 is moved linearly and is rotated about or in one or both of its respective end positions To fix split pin 200 in the respective end position in base 2, that is, to secure it. The cotter pin 200 can be secured in the respective end position in a known manner by positive locking and / or non-positive locking.

To connect the second holding device 4 to the base 2, the split pin 200 passes through part of an outer housing of the base 2, reaches through the second holding device 4 and then into another part of the base 2, which is between the two connecting arms 45, 46 of the second holding device 4 is formed.

Unlike the toe 1 Figure 1 to 10 , the toe piece 1 '' includes the Figures 11 and 12th a bracket 100 which extends over the end of the second holding device 4, which faces the ski boot in the downhill mode of the ski binding. The bracket 100 forms, for example, a stiffening element for the second holding device 4 and can be used as a snow scraper to remove snow from the underside of the sole of the ski shoe before entering the binding.
