Description

The invention relates to a mounting device for a ski binding for connecting a ski boot to a ski, with a front mounting unit for mounting between the ski and a front holding device of the ski binding and with a rear mounting unit for mounting between the ski and a rear holding device of the ski binding and a ski binding with such a mounting device.

Such mounting devices for ski bindings have been known for a long time. The distance between the ski boot and the top of the ski is increased by arranging a mounting plate between the front holding device and the ski or between the rear holding device and the ski. On the one hand, this improves the power transmission to the ski edge. Increasing the footprint also prevents the ski boot from touching the ground in corners. In this version of the mounting device, the front and rear mounting plates are not connected to one another.

A disadvantage of these mounting devices is the fact that the contact force of the skier in the loaded state of the ski is only transmitted to the ski in the area of the front or rear holding device of the ski binding via the front and rear mounting plate, while the middle area between the two holding devices can not be used to apply force.

In connection with different types of binding plates, it has also already been proposed to apply force to the central region of the ski in addition to the load in the toe or heel region of the ski binding.

From US 6,896,284 B2 such a device is known with a front binding plate and a rear binding plate. The binding plates are articulated to one another in the central region about an axis oriented transversely to the longitudinal axis of the device. The front binding plate seen in the direction of the ski tip here has an extension which is firmly connected to it and which extends over the joint axis and through which the platform can exert a force on the ski when the skier exerts a force on the binding in a vertical plane ,

A disadvantage of this embodiment, however, is the lack of variability in the arrangement, which results from the articulated connection between the two binding plates. Another disadvantage of the articulated connection between the binding plates is that only a single additional loading zone can be provided at the end of the extension of the respective binding plate. Furthermore, it can be disadvantageous in this embodiment that the flow of force is transmitted from the binding plate having the extension to the other binding plate via the articulated connection.

[0007] FR 2 675 391 A1 discloses a ski with a different type of stiffening element, which extends in the longitudinal direction of the ski and is guided through a binding plate for the arrangement of binding elements. The stiffening element is attached to side bearing walls in the central area by means of a bearing journal. This prior art is intended to counteract the deformations of the ski caused by cornering. However, the known design cannot contribute to the targeted introduction of force into the central region.

EP 0510308 A1 describes a different type of damping device for a ski, which is characterized by the arrangement of a viscoelastic damping element below a longitudinally extending, flexible strip on the ski surface. The damping device effectively reduces vibrations that occur during the journey, but the energy is reduced in the damping element.

[0009] WO 2004110573 A1 describes a ski with an extension with which a force is to be exerted in an area between a front binding part and the ski tip. The front binding plate, which is attached to the ski via a hinge part, is extended towards the front in the direction of the ski tip, with the free end of the extension in

Is slidably mounted on the ski in the longitudinal direction. In this embodiment, therefore, only the force introduced by the skier is distributed to the front area of the ski by means of the extension, but this prior art is not able to introduce vertical forces in the middle of the ski, which are absorbed in the front or rear area of the ski become.

[0010] DE 198 36 515 A1 describes a further binding plate which extends from the toe to the heel area and in which a device for force distribution is used. Here, an end region of the one-piece binding plate is pivotally connected to an intermediate carrier via a joint arrangement; the intermediate carrier is supported on the ski (or on another support carrier) by means of joint arrangements spaced in the longitudinal direction. This prior art has disadvantages similar to the binding plate of US 6,896,284 B2 discussed above.

[0011] In addition, EP 2 272 573 A1 discloses a ski which has an elongated force transmission element between the ski surface and the ski binding. The force transmission element extends continuously from a front area of the ski to a rear area of the ski. However, the force transmission element is intended to influence the flexural rigidity of the ski by distributing the forces evenly on the ski. For this purpose, the connection zones between the power transmission element and the ski are designed as longitudinal guides at the front or rear end, which allow a relative displacement between the power transmission element and the ski as a result of bending or bending of the ski. This state of the art can therefore make no contribution to improving the application of force in the middle area of the ski.

Accordingly, the object of the present invention is to provide a structurally simple, variably usable mounting device of the type mentioned, with which the introduction of force into the central region of the ski is improved.

According to the invention, a load introduction element for applying a compressive force to the ski is provided between the front assembly unit and the rear assembly unit, the load introduction element being connected to a front power transmission element extending in the longitudinal direction of the ski and / or to a rear power transmission element extending in the longitudinal direction of the ski , wherein the front power transmission element between the ski tip and the front mounting unit has a front force-absorbing part which can be fixedly connected to the ski or the rear power transmission element between the rear mounting unit and the ski end has a rear power-receiving part which can be fixedly connected to the ski, the front or rear power transmission element having a power-output part for power transmission the load introduction element between the front mounting unit and the rear mounting unit.

Accordingly, the mounting device has at least one elongated power transmission element which is fixed at the front or rear end, i.e. immobile at least in the longitudinal direction, is fixed to the ski. The force-absorbing part of the force-transmitting element absorbs the forces that arise when exerting a swing. Due to the bending of the ski in the loaded state, the force output part of the force transmission element is pressed against the load introduction element, which converts the longitudinal forces of the force transmission element into a compressive force perpendicular to the ski plane in the middle area between the two assembly units. In this way, forces can advantageously be introduced in a targeted manner into the central region of the ski. Accordingly, the ski can be loaded in the central region between the front and the rear holding device of the ski binding, so that an increased pressure is transmitted to the ski edge in this region. Advantageously, the swing radius can be shortened using the so-called carving technique. In addition, the skiing behavior of the ski can be improved.

For power transmission between the front or rear area of the ski and the central area of the ski, it is advantageous if the load introduction element has at least one wedge surface, preferably a front wedge surface at the front end and a rear wedge surface at the rear end, on which the power output part of the front or rear force

Transmission element attacks. In the loaded state of the ski, the flow of force can be transmitted from the front force-absorbing part to a front wedge surface of the load introduction element between the mounting units of the ski binding, which causes a greater deflection of the ski in the central area. The force output part of the rear power transmission element bears against a rear wedge surface of the load introduction element, so that forces introduced into the rear region of the ski can be transmitted to the load introduction element in the central region of the ski. Advantageously, the edge grip can hereby be increased. Due to the bending of the ski in the loaded state, the force output part is displaceable along the associated wedge surface of the load introduction element, the displacement of the force output part being converted via the wedge surface inclined to the ski plane into a compressive force directed perpendicular to the ski plane onto the central region of the ski. The front wedge surface is provided at the front end of the load introduction element and the rear wedge surface is provided at the rear end of the load introduction element in order to absorb the power flow of the front or rear power transmission element. The wedge surfaces preferably extend over substantially the entire width of the load introduction element, which enables effective power transmission.

To convert a longitudinal displacement of the front or rear power transmission element in the loaded state of the ski into a vertical compressive force on the central region of the ski has proven to be particularly advantageous if the wedge surface at an angle of inclination of 10 to 60 °, in particular from 30 to 40 °, is arranged to the longitudinal plane of the load introduction element. In this embodiment, therefore, a flat wedge surface is provided, which is inclined with respect to the longitudinal plane of the load introduction element or the longitudinal plane of the ski. On the one hand, this advantageously allows the ski to remain flexible when exerting a turn, and on the other hand ensures efficient power transmission to the load introduction element.

According to an alternative preferred embodiment, the wedge surface has a concave curvature, as a result of which a continuous increase in the pressure in the vertical direction is achieved when the load introduction element is displaced along the wedge surface. An embodiment is particularly preferred in which the wedge surface is formed in longitudinal section by a parabolic curve.

In order to achieve a stable and reliable mounting of the force output part on the load introduction element, it is advantageous if the force output part has at least one roll element that can be rolled off on the wedge surface of the load introduction element. When the ski is under load, the roller element can be rolled off along the wedge surface of the load introduction element, the roller element transmitting a force component directed perpendicular to the ski plane to the load introduction element. If the force output part carries at least two roller elements, the power flow can be transmitted particularly evenly between the force transmission element and the load introduction element.

An embodiment is particularly preferred in which the load introduction element can be pivoted essentially perpendicularly to the longitudinal direction of the ski by means of the force output part. The longitudinal displacement of the force output part along the load introduction element in the loaded state of the ski has the effect that the load introduction element is pivoted from a neutral position, which is preferably oriented essentially parallel to the ski plane, into a load position inclined thereto, in which a load component acting perpendicular to the ski plane is transferred to the ski.

In order to release the pivoting of the load introduction element in the loaded state of the ski, it is advantageous if the load introduction element has a convexly curved contact surface for resting on the ski. Accordingly, the load introduction element can be rolled off via the convexly curved contact surface on the top of the ski, the pivoting movement of the load introduction element being convertible into a compressive force on the ski between the front and rear mounting unit.

It has been found to be particularly advantageous if the convexly curved

AT514 662 B1 2019-09-15 Austrian

Patent Office

Contact surface has a radius of curvature of between 500 and 1000 mm, in particular between 700 and 800 mm.

In an alternative embodiment, the load introduction element has a substantially flat bearing surface for resting on the ski. This enables direct power transmission to be achieved, which is suitable for a particularly sporty driving style.

For mounting the load introduction element, it is advantageous if the load introduction element is connected to a holding element which can be fixed on the ski. For example, the holding element can be firmly connected to the ski by means of screws.

With regard to a simple and stable assembly of the load introduction element, it is also advantageous if the holding element is arranged in a recess of the load introduction element. The recess preferably extends over the entire height of the load introduction element perpendicular to the ski plane, so that the holding element is accessible from the side facing away from the ski. This makes it easier to mount the load introduction element on the ski. For this purpose, the holding element has suitable fastening means, for example screws, which can be firmly connected to the ski. An elongated holding element is preferably provided, which is arranged in a correspondingly shaped recess in the load introduction element.

According to a first preferred embodiment, the load introduction element and the holding element are slidably connected to one another in the longitudinal direction. This can be achieved in particular in that the holding element is arranged in the recess of the load introduction element with a guide in the longitudinal direction of the ski. In this embodiment, it is provided in particular that the displacement of the force output part in the loaded state of the ski is first converted into a displacement of the load introduction element in the longitudinal direction of the ski before the load introduction element transmits a compressive force on the ski perpendicular to the ski plane. This embodiment is preferably combined with a pivotable arrangement of the load introduction element. Longitudinal forces occurring at the force output part are converted into a combined movement of the load introduction element, which results from the pivoting of the load introduction element with simultaneous displacement of the load introduction element in the longitudinal direction of the ski. Accordingly, the load introduction element in this embodiment has a pivot axis that is displaceable in the longitudinal direction.

To limit the longitudinal displacement, it is advantageous if the load introduction element and the holding element have corresponding stops. In this embodiment, the load introduction element is shifted into a stop position by the force output part in the loaded state of the ski, with essentially no load being applied to the central region of the ski during the shift. When the stop position is reached, a further load on the load introduction element is converted into a compressive force perpendicular to the ski plane. In this way it can be achieved that forces introduced into the front or rear area of the ski are only delayedly transmitted to the central area of the ski when a minimum load is exceeded. This version has the particular advantage that the ski reacts less aggressively when turning. This version is particularly well suited for amateur sports.

In addition, it is advantageous if a damping element made of a rubber-elastic material is provided between the stops of the load introduction element and the stops of the holding element, whereby vibration damping is advantageously achieved. According to a preferred embodiment, the damping element completely fills the gaps formed between the stops of the load introduction element and the stops of the holding element. The damping element can be made from a rubber vulcanizate, for example SBR, NBR, EPDM, or from a thermoplastic elastomer, for example SBS, SEBS, TPU, with a Shore hardness of Shore 75 A to Shore 45 D, preferably Shore 85 A.

Preferably, the load introduction element from an unloaded state of the

AT514 662 B1 2019-09-15 Austrian

Patent Office

Skis corresponding middle position in one direction by a first distance into a first stop position against a front stop of the holding element and in the other direction by a second distance into a second stop position against a rear stop of the holding element. In this embodiment, therefore, a load transmission from the front force transmission element causes the load introduction element to be moved rearward into the first stop position. On the other hand, the power flow from the rear power transmission element is converted into a forward displacement of the load introduction element into the second stop position. If the ski is loaded evenly in the front and rear area, the load transfer element is in the middle position. Depending on the phase of the swing exercise, the load introduction element is shifted from the middle position backwards into the first stop position or forward into the second stop position, with a force transmission from the first or second stop position of the load introduction element to the central region of the ski.

If the first route and / or the second route is between 0.5 and 4 mm, in particular between 1 and 3 mm, on the one hand, a delay in power transmission which favors the skiing behavior of the ski can be achieved, while on the other hand an effective power transmission on the middle area of the ski when exercising turns.

According to a first embodiment, the stops are arranged on the load introduction element or on the holding element in such a way that the displacement to the rear due to a load in the front region of the ski and the displacement to the front due to a load in the rear region of the ski take the same distance.

[0031] In some applications, however, it is advantageous if the first route is longer than the second route. Shift to the rear 3 mm or shift to the front 1 mm. This design has the advantage that the ski reacts less directly when initiating a turn due to the longer displacement of the load introduction element, but a higher acceleration is achieved in the acceleration phase due to the shorter displacement of the load introduction element.

According to a further preferred embodiment, the load introduction element is arranged to be pivotable about a fixed pivot axis. In this embodiment, longitudinal forces on the force output part are therefore converted directly into a load on the load introduction element in the central region of the ski, which is directed perpendicular to the ski plane. In this way, the load introduction element can respond to the longitudinal forces introduced by the force transmission element essentially without delay. This achieves aggressive driving behavior, which is particularly suitable for a sporty driving style.

In order to improve the power transmission between the ski and the snow cover, it is particularly advantageous if the load introduction element is arranged substantially centrally between the front assembly unit and the rear assembly unit. The load introduction element is preferably set up for mounting around the apex of the ski which has a curvature or pretension.

To transmit forces between the front or rear area of the ski and the central area of the ski, it is particularly advantageous if the front or rear force transmission element between the front or rear force receiving part and a front or rear end of the front or rear assembly unit has a length of 100 to 500 mm, in particular of 200 to 300 mm, preferably of essentially 250 mm. Accordingly, the front power transmission element protrudes forwardly by the aforementioned length of, for example, essentially 250 mm from the front assembly unit, i.e. towards the ski tip. Accordingly, the rear power transmission element extends rearward from the rear assembly unit in the direction of the ski end. Advantageously, the pressure transmission can be significantly influenced over the length of the force arm formed between the force absorption part and the force output part. The longer this force arm, the greater the relative movement between the force transmission element and the load introduction element

AT514 662 B1 2019-09-15 Austrian

Patent Office ment, i.e. the more pressure can be transferred vertically or perpendicular to the ski plane. Accordingly, the length of the power transmission element can be selected depending on the discipline, such as downhill, giant slalom or slalom, but also to adapt to the individual runner behavior.

In order to be able to connect the force transmission element to the load introduction element arranged between the mounting units for the ski binding, it is advantageous if the front or rear force transmission element has a section running within the front or rear mounting unit. The power transmission elements are mounted so that they can be displaced in the longitudinal direction on the mounting units that can be connected to the ski surface. The arrangement of the force transmission element is preferably also such that the force transmission element is fixed in the direction perpendicular to the plane of the ski and therefore cannot deflect upwards when the force output part is pushed onto the load introduction element.

According to a preferred embodiment it is provided that the load introduction element has a front wedge element with a front wedge surface and / or a rear wedge element with a rear wedge surface, the front or rear wedge element being detachably connected to a fastening element which can be fixed on the ski. In this two-part or three-part design of the load introduction element, the wedge elements can be easily removed from the fastening element in order to attach another wedge element, for example with a different inclination of the wedge surface, to the fastening element. It is advantageously not necessary to completely disassemble the assembly device. In this embodiment, the fastening element can on the one hand be fastened directly to the ski or can be fastened to the ski by means of a holding element, in particular as described above. The connection between the wedge element and the fastening element is preferably detachable without tools, which makes the replacement of the wedge element particularly simple. For example, a snap connection can be provided.

An embodiment is particularly preferred in which the fastening element has the cutout for the holding element. With regard to the preferred configuration of the holding element or the displaceable mounting between the load introduction element and the holding element, reference is made to the above statements.

According to an alternative embodiment, the exchange of the load introduction element is facilitated in that the load introduction element has a first component with a front wedge surface and a second component with a rear wedge surface, the first component being detachably connected to the second component. The components preferably have overlapping sections in the longitudinal direction, which in particular have the cutout for the holding element described above. To replace the load introduction element, the connections between the components of the load introduction element can preferably be released without tools, in particular snap connections being provided.

The assembly device described above can be made of a plastic, in particular fiber-reinforced plastic, for example a glass fiber-reinforced polyamide, a carbon fiber-reinforced polyamide, a fiber-reinforced polyoxymethylene, a fiber-reinforced polypropylene, in particular in an embodiment as an injection molded part, or also of metal, in particular light metal, for example from an aluminum alloy or a magnesium alloy. In the case of the use of metals, the assembly device can be produced as a milled part or as a die-cast part. Of course, the individual components can also be constructed from combinations of different materials. For example, the power transmission elements can be designed as plastic injection molded parts, long fiber reinforced laminate blanks can also be extrusion-coated as stiffening elements in a hybrid method known per se, and the load introduction element made of metal, for example as an aluminum die-cast part. Within the scope of the invention, however, any material combination can be selected which is suitable for the various applications, for example in racing or in amateur sports or in the individual disciplines, such as downhill or slalom.

The object underlying the invention is also achieved by a ski binding of the type mentioned, in which the assembly device described above is provided. Thus, reference can be made to the above statements.

The invention will be explained in more detail with reference to the embodiments shown in the drawings. The drawings show:

1 shows a ski 1 with a ski binding 2 with which a boot 3 can be fixed on the ski 1. The ski binding 2 is mounted on a mounting device 4 (see FIG. 3), which has a first, front mounting unit 5 for arrangement between the ski 1 and a front holding device 6 of the ski binding 2 and a second, rear mounting unit 7 for arrangement between the ski 1 and a rear holding device 8 of the ski binding 2. The front mounting unit 5 and the rear mounting unit 7 are spaced apart from one another in the longitudinal direction and are not connected to one another. To increase the footprint, the assembly units 5, 7 are plate-shaped. The ski binding 2 is, as is customary in the prior art, in the form of a safety ski binding which has a toe device or toe piece as the front holding device 6 and a heel device or heel piece as the rear holding device 8. The ski 1 has an upward curved blade 9 at the front end and an upward curved ski end 10 at the rear end. In addition, the ski 1 has a pretension, illustrated in the drawing by arrow 12, which causes a concave curvature of the ski 1 between the shovel 9 and the ski end 10. Due to the preload, the ski 1 is only in front and on one in the unloaded state

Patent office rear support area on a flat surface 11.

Fig. 2 shows the ski 1 in the loaded state, wherein the body weight of the runner is introduced via the shoe 3 in the front 6 and in the rear holding device 8. Here, the body weight of the runner is divided into two forces F1 and F2 perpendicular to the main plane of the ski 1. In addition, forces F3 oriented in opposite directions occur on the front holding device 6 and on the rear holding device 8 parallel to the longitudinal axis of the ski 1. The forces F3 result from the (not shown) safety mechanism of the ski binding 2, with which the triggering function of the ski binding 2 is ensured under a predetermined load.

As can also be seen from FIGS. 1, 2, the cross section of the ski 1 varies in the longitudinal direction, the cross-sectional area of the ski 1 being largest in the central region between the front holding device 6 and the rear holding device 8. Accordingly, the ski 1 has the highest rigidity in the central area.

When using the two-part mounting device 1 shown in Fig. 1, consisting of the front mounting unit 5 and the rear mounting unit 7, the contact force of the runner in the loaded state of the ski 1 can not in the middle region of the ski having the highest rigidity 1 between the toe apparatus and the heel apparatus. This means that the pressure distribution of the ski 1 in the middle region follows a flattened curve with which the waist radius of the ski 1 can disadvantageously not be optimally used.

3 to 6, a first embodiment of a mounting device 1 is shown, with which this disadvantage is eliminated. In the following, only the differences from the assembly device 1 according to FIG. 1,2 will be discussed.

As can be seen from FIG. 3, the mounting device 4 in the embodiment shown has a load introduction element 13, which is arranged between the front mounting unit 5 and the rear mounting unit 7 in order to apply a compressive force to the central region of the ski 1. In the embodiment shown, the load introduction element 13 is arranged essentially centrally between the front assembly unit and the rear assembly unit at the apex of the curvature of the ski 1. The load introduction element 13 interacts on the one hand with a front power transmission element 14 and on the other hand with a rear power transmission element 15. The front power transmission element 14 has in the front region of the ski 1 between the ski tip 9 and the front assembly unit 5 a front force-absorbing part 16 which is fixedly or immovably connected to the ski 1. In addition, the front power transmission element 14 in the middle region of the ski 1 between the front mounting unit 5 and the rear mounting unit 7 has a front power output part 17 which is arranged to be movable in the longitudinal direction of the ski 1. Correspondingly, the rear power transmission element 15 between the rear mounting unit 7 and the ski end 10 has a rear power absorption part 18 which is fixedly connected to the ski 1 and a rear power output part 19 in the central region of the ski 1.

For the purposes of this disclosure, the terms “rear and” front refer to the longitudinal direction of the ski 1 in the direction of the ski tip 9.

As can also be seen from FIG. 3, the front force transmission element 14 has a section 14 ′ running inside the front mounting unit 5 and a section 14 running outside the front mounting unit 5 in the direction of the ski tip 9. Accordingly, the rear power transmission element 15 has a section 15 ′ running inside the rear mounting unit 7 and a section 15 running outside the rear mounting unit 7 in the direction of the ski end 10. The section 14 of the front force transmission element 14 in the embodiment shown has an extension of essentially 250 mm between the front end of the front force receiving part 16 and a front end of the front assembly unit 7. The section 15 of the rear power transmission element 15 has the same length as the section 14 of the front power

8.18

AT514 662 B1 2019-09-15 Austrian

Patent Office wearing element 14. The length of these sections can be varied depending on the application.

As can also be seen from FIG. 3, the front power output part 17 and the rear power output part 19 in the embodiment shown are designed as a front roller element 20 and as a rear roller element 21, the front roller element 20 being along a front wedge surface 22 at the front end of the Load introduction element 13 and the rear roller element 21 is guided along a rear wedge surface 23 at the rear end of the load introduction element 13. In the embodiment shown, the front wedge surface 22 and the rear wedge surface 23 are arranged at an inclination angle of essentially 30 ° to the longitudinal plane of the ski 1.

As can also be seen from FIG. 3, the load introduction element 13 can be pivoted by means of the force output parts 17, 19 about a pivot axis which runs essentially perpendicular to the longitudinal direction of the ski 1 in the longitudinal plane of the ski 1. In order to release the pivoting, the load introduction element 13 has a convexly curved support surface 25 which rolls on the top of the ski 1 when the load introduction element 13 is loaded. In the embodiment shown, the convexly curved contact surface 25 has a radius of curvature of essentially 700 mm.

As can be seen from FIGS. 4 to 6, the load introduction element 13 is connected to a holding element 26 which can be fixed on the ski 1 and which is arranged in a central recess 27 of the load introduction element 13. The holding element 26 has fastening openings for corresponding fastening means, here screws 28 ', for mounting the holding element 26 on the ski 1. In the embodiment shown, the load introduction element 13 and the holding element 26 are slidably mounted to one another in the longitudinal direction of the ski 1. For this purpose, the holding element 26 is arranged with play in the longitudinal direction and without play in the transverse direction within the recess 27 of the load introduction element 13. The load introduction element 13 forms a front stop 28 on a front boundary surface of the recess 27 and a rear stop 29 on a rear boundary surface, the end faces of the holding element 26 forming corresponding counter stops 30, 31.

As can also be seen from FIGS. 3 to 6, the load introduction element 13 is in the unloaded state of the ski 1 in a central position in which a gap is formed between the holding element 26 and the stops 28, 29 of the load introduction element 13, so that, depending on the application of pressure, the load introduction element 13 can be displaced backwards by the same distance of, for example, 2 mm into a first stop position or forward by the same distance into a second stop position via the front power output part 17 or the rear power output part 19.

According to an alternative embodiment, different gaps are formed between the stops 28, 30 or between the stops 29, 31 in the unloaded state, so that the load introduction element 13 by a first distance, for example 3, when the front area of the ski 1 is loaded mm, is shifted backwards and is shifted forward by a second, different distance, for example 1 mm, when there is a load in the rear area of the ski 1. This embodiment has the advantage that the ski 1 reacts less directly when initiating a turn, but instead a higher acceleration is achieved in the acceleration phase of the turn.

In addition, a damping material made of a rubber-like material (not shown) can be arranged in the free spaces between the stops 28, 29 of the load introduction element 13 and the stops 30, 31 of the holding element 26.

Accordingly, the load introduction element 13 can shift depending on the temporal phase of the swing due to the gap in its longitudinal position. When the runner initiates the turn, the front ski is first bent. Due to the longitudinal force of the force transmission element 14, the load introduction element 13 is displaced in the longitudinal direction towards the ski end 10, with at the same time a rotation of the front end of the load introduction

Patent office element 13 is initiated towards the ski surface. The consequence of this is that the deflection of the ski 1 takes place with a time delay in the central region and the ski 1 reacts less aggressively. In the next swing phase, the runner shifts his center of gravity towards the center so that the deflection of the front and rear skis are balanced. Thus, the load introduction element 13 is shifted back to the central position in its longitudinal position and both force transmission elements 14, 15 stabilize the assembly device

4. In the last phase of the turn, the runner shifts his center of gravity towards the end of the ski 10. As a result, the load introduction element 13 is moved forward and at the same time pivoted at its rear end towards the ski surface. As a result, the ski 1 is bent more strongly in the central region. This additional deflection represents an energy store, which leads to an increased acceleration from the swing after relieving the load on the ski 1.

As can also be seen from FIGS. 3 to 6, in another embodiment, the load introduction element 13 can be arranged to be immovable in the longitudinal direction by means of an (optional) swivel axis 32. In the assembled state, the pivot axis 32 extending perpendicular to the longitudinal direction of the ski 1 passes through the load introduction element 13 and the holding element 26, as a result of which the displacement of the holding element 26 within the recess 27 is blocked. In this embodiment, the load application member 13 responds directly, i.e. without delay, since the force from the force transmission element 14, 15 is converted directly into a rotation of the load introduction element 13, as a result of which a vertical force is introduced in the middle of the ski. Due to the detachable arrangement of the pivot axis 32, the mounting device 2 can be used variably.

According to a (not shown) variant of the embodiment according to FIGS. 3 to 6, the load introduction element 13 has a front wedge element with the front wedge surface 22 and a rear wedge element with the rear wedge surface 23, each of which is detachable with a recess 27 for the retaining element 26 having fastener are connected. As a result, the wedge elements can be replaced in a simple manner, for example to provide a wedge element with a different inclination of the wedge surface. Advantageously, it is not necessary to disassemble the assembly device 4. Due to the detachable arrangement of the wedge elements, the effect of the load introduction element 13 can be varied in a variety of ways by using different wedge elements. The wedge elements are preferably connected to the fastening element via snap connections.

7 to 9 show a further embodiment of the mounting device 4, only the differences from the embodiment according to FIGS. 1 to 4 being discussed below. In the embodiment shown, the load introduction element 13 has an essentially flat bearing surface 33 for resting on the ski 1. A particularly direct power transmission to the central region of the ski 1 can hereby be achieved. The load introduction element 13 can be securely mounted on the ski 1 by means of suitable fastening means, screws 28 ′ in the embodiment shown. The screws 28 'are arranged in a recess 27' which is formed on a central part 34 of the load introduction element 13. The middle part 34 is connected at the front end to a front ramp part 35, which has the front wedge surface 22, and at the rear end to a rear ramp part 36, which has the rear wedge surface 23.

As can also be seen from FIGS. 7 to 9, the front force transmission element 14 has at the front end the front force absorption part 16, which has holding means 37 for fixed or immovable mounting on the ski 1. The rear force absorption part 18 of the rear force transmission element 15 has corresponding holding means 37. The front mounting unit 5 and the rear mounting unit 7 can be firmly connected to the ski 1 via mounting means 38.

As can also be seen from FIGS. 7 to 9, the force transmission elements 14, 15 are displaceably guided on the mounting units 5, 7. The sections 14, 15 of the power transmission elements 14, 15 are formed by flat longitudinal elements 39. The sections 14 ', 15' within the assembly units 5, 7 have flat longitudinal elements 40, which one

10/18

AT514 662 B1 2019-09-15 Austrian

Patent office have a smaller width than the flat longitudinal elements 39 connected therewith outside the mounting units 5, 7. The flat longitudinal elements 39 are connected to the force output parts 17, 19, which are wider and higher than the flat longitudinal elements 39. The force output parts 17, 19 are arranged with a precise height within the assembly units 5, 7, so that the force transmission elements 14, 15 which are longitudinally displaceable in the loaded state of the ski 1 cannot deflect perpendicular to the ski plane when the roller elements 20, 21 of the force output parts 17, 19 are pushed onto the wedge surfaces 22, 23.

As can also be seen from FIG. 9, the load introduction element 13 has a front wedge element with the front wedge surface 22 and a rear wedge element with the rear wedge surface 23, each of which is detachable with a recess 27 for the holding element 26, directly are attached to the ski 1 fastener.

10 to 12 show a further embodiment of the mounting device 4, in which the force transmission elements 14, 15 have depressions 41 on the underside. The depressions 41 advantageously bring about a weight reduction. In the embodiment shown, the load introduction element 13 is formed by two nested components 13 ', 13 which are detachably connected to one another and which have overlapping sections in the longitudinal direction. This embodiment has the advantage that the components 13 ', 13 "can be pulled out laterally by loosening the connections between the components 13', 13" in order to carry out an exchange of the load introduction element 13. Advantageously, the load introduction element 13 can therefore be replaced by another load introduction element 13, for example with a different angle of the wedge surfaces 22, 23, without the assembly device 4 having to be dismantled. This has the advantage that the driving characteristics can be easily changed directly on the slopes. In this embodiment, it is preferably provided that the detachable connection between the components 13 ', 13 has a screw or a snap connection. In addition, it can be seen from the drawing that the nested components 13 ', 13 "have a recess 27 for arranging the fastening means for mounting on the ski. In the embodiment shown, the cutout 27 serves to receive the holding element 26.
