DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for adjusting an angle in the sideways direction between a ski boot or skier's leg and sliding surface of an associated ski.
In the case of modern ski boots, it is frequently possible to have a pivoting adjustment of the boot shaft relative to the boot sole about a longitudinal axis of the boot. An appropriate adjustment--also referred to as canting adjustment--can compensate for anatomical peculiarities of the skier, e.g. bow legs or knock knees, such that, when the legs are comfortably positioned, the sliding surfaces of the ski are located in a common plane or in mutually parallel planes. This makes it easier for the skier to avoid undesired canting of the ski.
In the case of a ski known from DE 26 03 676 A1, there is arranged between the ski boot and ski a standing plate, of which the boot-side, top side is arranged in a pivotably adjustable manner about a longitudinal axis of the ski relative to the ski-side, underside, it being the case that said pivoting adjustment takes place by a longitudinal adjustment of wedge elements between the top side and underside of the standing plate. A canting adjustment is also thereby possible.
Irrespective of the canting adjustment in each case, during turning the angle at which those edges of the ski which are on the inside of the turning curve dig into the underlying surface is determined by the angle at which the skier inclines his/her legs toward the inside of the turning curve in comparison with the situation where he/she is skiing normally straight ahead.
The object of the invention, then, is to present new ways of controlling the canting of the ski.
This object is achieved according to the invention in that an adjusting device, which operates as a function of parameters correlated with turning, causes parameter-dependent pivoting of the ski boot or of the boot shaft about a longitudinal axis of the ski relative to the sliding surface of the ski and/or a parameter-dependent adjusting force, which tries to pivot the boot or its shaft in sideways direction relative to the sliding surface of the ski such that, during turning, at least one predetermined ski is guided with edge pressure and/or canting which is increased in relation to the sideways inclination of the boot or leg.
In this context, it is provided, in particular, that, via the adjusting device, bending of the respective ski which occurs during turning--at least when the skier or his/her legs are inclined obliquely with respect to the inside of the turning curve--controls sideways tilting of the ski boot or of its shaft relative to the associated ski such that the vertical axis of the sliding surface of the predetermined ski, in particular of the ski on the outside of the turning curve, is inclined toward the inside of the turning curve to a more pronounced extent than the vertical axis of the associated ski boot or its shaft.
The invention is based on the general idea of using parameters which are characteristic of turning, to be precise in particular the bending of the ski which occurs during turning, the longitudinal ends of said ski bending upward, in the direction of the vertical axis of the ski, relative to the central region of the ski during turning, for the purpose of controlling sideways pivoting of the ski boot or its shaft or of controlling a corresponding adjusting force, in order to increase the edging or edge pressure at least of one ski during turning.
In the case of current skiing techniques, it is the ski on the outside of the turning curve in particular which is subjected to loading during turning, with the result that the edging of this ski during turning is of increased importance. Accordingly, it is expediently provided for the adjusting device to be designed such that it is the ski on the outside of the turning curve in each case which has the increased edging or edge pressure. However, it is also possible, in principle, to cause a pivoting adjustment or adjusting force for increased edging or edge pressure for the ski which is on the inside of the
