Description

The invention relates to a device for attaching a ski binding on a ski, with a mountable on the ski binding plate, wherein the attachment of the binding plate on the ski takes place with the interposition of supporting elements.

Such a device is for example from the DE 41 00 327 C2 known. In the known embodiment, the longitudinal position of the support is adjustable. As a result, the vertical forces to which the ski is subjected can be localized in areas adjustable along its longitudinal direction, even though the shoe is based on conventional support surfaces. By varying the support points of the shoe on the ski, the mechanical response characteristics of the binding plate should be able to be modified to the loads exerted on the binding plate during skiing.

Not recognized in the prior art, including the constructions according to the WO 83/03360 or EP 0 182 776 A2 include making the support of the binding plate on the ski on the one hand in the manner of a "chassis", which leaves the vibrations of the ski substantially unaffected, but at the same time does not transfer to the shoe, and on the other hand to make that the effective inner edge longer is as the outer edge.

The patent US-A-2003 0085550 also discloses a binding plate with interposition of support elements, wherein both support elements extend approximately parallel to the ski longitudinal direction and wherein the first lying on the inner edge support member is longer than the second outer support member.

Accordingly, the present invention has the object to design a device of the type mentioned above, that with the utmost quietness for the shoe, the vibration of the ski is substantially unaffected, and that beyond the effective support of the shoe on the binding plate is inside longer as the outside with the result that the effective inner edge is correspondingly longer than the effective outer edge of the ski.

This object is achieved by the characterizing features of claim 1, 2, 3 or 4, wherein advantageous developments and embodiments of the inventive concept are described in the subclaims.

Accordingly, the device according to the invention is characterized by an inner support member, which is the inner edge of the ski, and an outer support member which is associated with the outer edge of the ski, wherein both support elements extend approximately parallel to the ski longitudinal direction and wherein the first inner support member is longer than the second outer support element. In this way it can be achieved that the same support of the binding plate is longer inside than outside the elevation is formed substantially T-shaped, wherein the long leg of the T-shaped elevation of the inner support member and the short leg of the outer support member forms. This substantially symmetrical design of the survey leads to particularly good driving characteristics, wherein the inner support member and / or the outer support member are integrally formed. This ensures a particularly simple and quick installation of the binding plate. In addition, an adjustment of the individual support elements omitted, since they are already aligned.

In this case, the two support elements may comprise a continuous elevation on a surface of the plate facing the ski in use, which is wider in the region of the outer support element than in the region of the inner support element. Due to the wider in the region of the outer support member elevation than in the region of the inner support member profiling and thus delimitation of the two support elements takes place insofar from each other, as the wider area of the survey is necessarily shorter than the adjacent narrower area of the survey. As a result, a shorter effective length is achieved in the region of the outer support element than in the region of the inner support element.

This makes the ski much easier to control. It must be borne in mind that when cornering, the skier rolls almost forward over the big toe bale in the ski boot, with the result that the pressure is shifted inwards to the front. This pressure is transmitted to the inner edge of the ski via the longer inner support element. The front portion of the inner support element acts as a kind of "control pedal" for cornering.

In an alternative solution can be provided that the two support elements are trapezoidal, wherein the longer of the parallel trapezoidal sides, the inner support member and the shorter of the parallel trapezoidal sides comprises the outer support member. The inner and outer support member are thus integrally formed. In this case, a plurality of such trained support elements, d. H. trapezoidal support elements are combined with each other, wherein the longer of the parallel trapezoidal sides are each associated with the inner edge of the ski. As a result, a longer effective edge is generally installed on the inside edge side of the ski, whereas the effective edge of the support elements on the outside of the ski is correspondingly shorter.

In another alternative, it may be provided that two parallelogram-shaped support elements are arranged in a V-shape, such that the more widely spaced leg ends form an effective length of the inner support member and the closer leg ends an effective length of the outer support member. Again, it is possible to combine a plurality of V-shaped support elements arranged together, such that an M-shaped structure is formed. It is important that the effective length of the inner support member is greater than the effective length of the outer support member.

Furthermore, in a further alternative solution two double-L-shaped support elements may be provided, which are arranged axially symmetrically, wherein each support element has two offset parallel legs, which are respectively associated with the inner edge and the outer edge of the ski. The more spaced parallel legs of the double L-shaped support members form the effective length of the inner support member. The closer parallel legs of the double L-shaped support members form the effective length of the outer support member.

It has also been shown that the edge grip is considerably higher due to the construction according to the invention. The ski does not tend to drift over a ribbed ice track. Also, the risk of intersection when driving straight ahead is significantly reduced. It should be remembered that nowadays strongly fitted skis, so-called carving skis, are increasingly being used. Especially with such Skikonstruktionen the device according to the invention is particularly advantageous.

A preferred embodiment is modular. This means that, in particular, the outer support element is exchangeable, in particular by a higher, flatter, harder or softer support element to be replaced. When using a higher one Supporting element on the inside can in particular reduce the risk of an intersection of the ski when driving straight ahead or even avoided altogether, as this additionally shortens the outer pressure line in relation to the inner pressure line. The control is thus essentially only over the inner edge of the ski.

In order to promote the aforementioned "chassis effect", the support elements are formed like a flat bar and made of the same material and / or material structure, in particular wood or wood / plastic composite, such as the binding plate.

Furthermore, it can be provided to space the inner support element sections in the longitudinal direction of the ski more or less widely in the case of a split inner support element. A smaller distance allows a more aggressive, more revving handling, while a longer distance encourages less aggressive driving.

Preferably, the distance between the front end of the foremost inner support member portion and the rear end of the rearmost inner support member portion by a maximum of 40-60 mm, in particular about 50 mm variable.

In a preferred embodiment, the binding plate is securable to the ski by bolts extending through the support members. In this case, the screw passages are formed in the support elements either slot-like in the longitudinal direction or have an inner diameter which is significantly, in particular by about 1.0 to 2.0 mm larger than the diameter of the mounting screws.

It is important for the assembly that the fastening screws are only screwed in so far that a minimal clearance between the binding plate and the supporting element on the one hand and the supporting element and ski on the other hand is present. This minimal play allows a micro-relative movement between the aforementioned parts and has the advantage that vibrations of the ski are no longer transmitted to the binding plate or the shoe of the skier, without the vibrations are taken out of the ski. The ski can be essentially unaffected by the binding system continuously, ie swing over its entire length. Counterpressure by the device according to the invention arises only when the ski running surface is pressed flat in the zero position or horizontally. Until then, however, the construction according to the invention has hardly any influence on the vibration behavior of the ski. In this respect, the device according to the invention is comparable to the "chassis" of a motor vehicle.

Due to the concentration of force or pressure transfer to the inner edge of the ski, the torsional rigidity of the same is not or only insignificantly influenced. At best, the construction according to the invention gives a slight additional torsional rigidity.

As already mentioned above, the inner support element is preferably slightly higher than the outer support element. For racers the height difference is usually 1.0 mm. For normal runners, a height difference of 0.5 mm is sufficient.

In a particularly preferred embodiment, the inner support member and the outer support member are integrated into a plate, in particular in the mounting plate, wherein the two support elements are delimited from one another by a profile formed in the plate at least in sections. This embodiment is particularly advantageous in terms of manufacturing aspects, since it is sufficient for the formation of the inner and outer support member to profile the ski in use facing side of the plate accordingly.

For reasons of flexibility, grooves arranged transversely to the longitudinal extension may be formed at least in the region of the outer support element.

In a particularly preferred embodiment, a rotatably mounted and fixable elongated support member is combined with another support member. By rotating the support element, the distance of an axial end of the elongate support element from the further support element can be adjusted, so that the fastening device can be adapted to the driving behavior of the respective skier.

The following is based on the Fig. 1 a device explained in more detail with reference to a schematic perspective view. This shows a device 10 for attaching, for example, a front and heel cheek comprising ski binding on a ski 11, with a mountable on the ski 11 binding plate 12, wherein the attachment of the binding plate 12 on the ski 11 with the interposition of supporting elements 13, 14 takes place. A first inner support member 14 is the inner edge 15 and a second outer support member 13 is associated with the outer edge 16 of the ski 11, wherein both support elements extend approximately parallel to the ski longitudinal direction. The first inner support member 14 is longer than the second outer support member 13. The outer support member 13 is disposed approximately centrally relative to the inner support member 14. The inner support member 14 is divided into two and comprises a front portion 17 and the rear portion 18. These two portions are formed as well as the outer support member 13 each have a flat bar-like. They consist as well as the binding plate 12 made of wood, wood composite or wood / plastic or wood / metal or metal / plastic composite material.

The outer support member 13 is preferably interchangeable between ski 11 and binding plate 12 inserted. The inner support element 14 is preferably formed higher over the entire length, at least over a portion of the longitudinal extent than the outer support element 13, in particular by about 0.5 to 1.5 mm, in particular 0.5 to 1.0 mm higher.

As also already mentioned, the inner support element sections 17, 18 can be more or less widely spaced from each other. This depends on how aggressive the driving behavior of the user is.

The attachment of the binding plate 12 on the ski 11 is carried out by extending through the support members 13, 14 screws. Preferably, the passages or bores in the support elements 13, 14, through which extend the fastening screws, significantly larger, in particular by 1.0 to 2.0 mm larger than the diameter of the associated fastening screws. This microgame between binding plate on the one hand and support elements on the other hand and support elements on the one hand and ski on the other hand possible. For mounting it should be mentioned that the fastening screws are of course only screwed in so far that the above-described minimal play between binding plate and support elements on the one hand and supporting elements and skis on the other hand is obtained with close contact of the aforementioned components, which allows relative micro-movements between the aforementioned parts , in such a way that for the skier despite vibration of the ski is guaranteed absolute smoothness. Accordingly, the support elements 13, 14 act as a chassis between the wheels on the one hand and the vehicle cabin of a vehicle on the other.

By the described construction, the inner edge is effective almost over the entire length of the ski, while the outer edge is effective only in the region of the binding substantially.

The front inner support member portion 17 acts as a kind of "control pedal" for cornering, since the natural support of the skier on the ski takes place on this front support member portion 17 in a change of direction.

In principle, it is also conceivable to form the outer support element 13 more, in particular two parts.

Furthermore, it can be provided to seal the gap between binding plate and ski deck, so that no snow or ice can get into this space, which could adversely affect the vibration behavior of the ski.

Embodiments for the realization of the device according to the invention are in the FIGS. 5 to 6 shown.

Fig. 2 relates to an example in which the support elements are T-shaped. In this case, the longer inner support member 14 and the outer shorter support member 13 are integrated into a plate, which may be, for example, the mounting plate 12. The inner and outer support members 13, 14 are delimited from each other by a profile formed in the plate. The delimitation by the profiling takes place in that the two support elements 13, 14 are formed as a survey 19. The elevation 19 is provided on the surface of the plate 12 facing the ski in use. The elevation 19 is designed so that the elevation 19 is wider in the region of the outer support element than in the region of the inner support element 14. In particular, the elevation in the region of the outer support element 13 extends from the inner edge 15 of the ski to the outer edge 16. Die Elevation in the region of the inner support element is narrower, as in Fig. 2 to recognize. In other words, the profile provided in the plate 12 comprises two recesses 29, 30 which are provided on both sides of the region of the outer support element 13, the two recesses 29, 30 extending approximately in their transverse direction to half of the plate. The elevation 19 therefore has a T-shaped configuration, with the long leg 20 of the T-shaped elevation forming the inner support element 14, ie the longer support element, and the short leg 21 forming the outer support element, ie the shorter support element. The two recesses or recesses 29, 30 are filled with a filling material, for example with foam. In any case, it is important that the plate 12 in the region of the recesses 29, 30 has no direct contact with the ski, so that a delimitation of the inner support member 14 from the outer support member 13 is carried out by the profiling thus carried out.

The profiling is also good in the FIGS. 3, 4 to recognize.

The grooves 22 provided for influencing the flexibility of the fastening plate 12 at least in the region of the outer supporting element 4 are arranged transversely to the longitudinal extent.

An embodiment of the formation of the support elements is in Fig. 5 shown. Accordingly, the inner and outer support members 13, 14, be formed in one piece in the form of a trapezoid. In this case, the inner support member 14 is formed by the longer of the parallel trapezoidal sides 23 and the outer support member 13 by the shorter of the parallel trapezoidal sides 24. The longer trapezium side 23 is assigned to the inner edge of the ski. It is also possible to have several trapezoidal Support elements to combine with each other, wherein the longer of the parallel trapezoid sides 23 are each associated with the inner edge of the ski.
The oblique sides arranged between the parallel sides 23, 24 can be curved, in particular concave.

Another possibility for the realization of the support elements is to arrange two parallelogram-shaped support elements V-shaped, as in Fig. 5 shown. At this point it should be noted that the in Fig. 5 illustrated embodiments may be combined with each other, but the V-shaped support elements would have to be rotated by 180 ° for combination with the trapezoidal support element, so that the effective edge of the inner, longer support member is assigned to each of the ski inner edge.

In the V-shaped arrangement of the support members, the more spaced apart leg ends 25 form an effective length or edge of the inner support member 14. The opposite, closer together leg ends 26 of the V-shaped arrangement form the effective length or edge of the outer Support element 13. By changing the angle between the two support members, the effective length of the inner support member 13 can be varied.

A flexible adaptation of the fastening device device to the driving style of the respective user can by the also in Fig. 5 shown rotatably mounted elongated support element done. As in Fig. 5 can be seen, the elongated support member is rotatably mounted centrally and fixed at its two longitudinal ends by screws, which are guided in curved grooves. If this elongated support member is combined with another support member, by rotation of the elongated support member of the distance of the one end of the support element relative to the further support member can be changed, so that the effective length of the inner support member 13, ie the region of the support element, the Inner edge of the ski is assigned, can be adjusted.

In Fig. 6 another embodiment of the invention is shown in which two double-L-shaped support elements are arranged axially symmetrically. The double L-shape is formed by each support element having two offset parallel legs 27, 28 which are connected by a transverse leg 31 arranged in the longitudinal direction of the ski. As in Fig. 6 can be seen, the staggered parallel legs 27, 28 each have a double-L-shaped support member each of the inner edge 15 and the outer edge 16 of the ski 11 assigned. As a result of the axisymmetric arrangement of the two support elements, the two parallel legs 27 assigned to the inner edge 15 are more widely spaced than the two oppositely disposed parallel legs 28 which are assigned to the outer edge 16 of the ski 11. This ensures that the effective length of the inner support element 14, which is defined by the two of the inner edge 15 associated leg 27, is greater than the effective length of the defined by the two legs 28 outer support member thirteenth

All disclosed in the application documents features are claimed as essential to the invention, as far as they are new individually or in combination over the prior art.
