Abstract
A configuration contains a ski binding and a ski boot, whereby a sole of the boot is connected to the ski binding by a maintaining element and performs a rolling off movement when the heel is lifted. The maintaining element contains at least three fixed points, whereby at least one fixed point acts as a rotational point in the region of the ski when the ski boot is lifted, at least one second point is connected to the sole of the boot in the ball region, and at least one third point is provided in the region of the tip of the sole in order to couple the ski binding to the ski boot.
Claims13
A configuration, comprising:
- a ski boot having a boot sole with a tip and a heel;
- a ski binding having a retaining element with at least three fixed points disposed in corners of an imaginary triangle for connecting said boot sole to said ski binding, said boot sole being pivotable, during a lifting of said heel, via a pivotable movement about an axis located on an upper side of a ski in a region of said tip of said ski boot functioning as a first fixed point, said retaining element having a rear retaining element disposed in a ball region of a foot functioning as a second fixed point, a front retaining element serving as a third fixed point to couple said ski binding with said boot, whereas a relative position of the three fixed points is fixed during the lifting of said heel;
- said ski boot having a sole with a rounded outer sole surface, said rounded outer sole surface defining a toe spring measured from a ball contact point of said sole to a tip region of said sole;
- and
- said rear retaining element being pivotable about a stationary axis extending transversely to a longitudinal axis of the ski, said stationary axis being arranged in the toe spring below the rounded outer sole surface.
A ski boot for a ski binding formed as a three-part binding unit including a front retaining element configured as a hook element, a rear retaining element configured as a hook element, and a hinge disposed therebetween and forming an axis of rotation, the ski boot comprising:
- a sole including a tip and a heel, said sole having a rounded outer sole surface, said rounded outer sole surface defining a toe spring measured from a ball contact point of said sole to a tip region of said sole;
- and
- a stepped extension in a region of said sole tip, said stepped extension projecting in a running direction for receiving a hook surface of the front retaining element on an upper surface of the extension;
- the stepped extension having a groove formed therein for receiving the front retaining element configured as a hook element, in order to take up transverse forces in engagement with the front retaining element;
- and
- a relative position of the front retaining element, the rear retaining element and the hinge being fixed during a lifting of said heel, said rear retaining element being pivotable about a stationary axis extending transversely to a longitudinal axis of the ski, said stationary axis being arranged in the toe spring below the rounded outer sole surface.
A ski boot for a ski binding formed as a three-part binding unit including a front retaining element configured as a hook element, a rear retaining element configured as a hook element, and a hinge disposed therebetween and forming an axis of rotation, the ski boot comprising:
- a sole including a tip and a heel, said sole having a rounded outer sole surface, said rounded outer sole surface being rounded starting from a ball contact point forwardly in a direction to said tip of said ski boot;
- and
- a stepped extension in a region of said sole tip, said stepped extension projecting in a running direction for receiving a hook surface of the front retaining element on an upper surface of the extension;
- the stepped extension having a groove formed therein for receiving the front retaining element configured as a hook element, in order to take up transverse forces in engagement with the front retaining element;
- and
- a relative position of the front retaining element, the rear retaining element and the hinge being fixed during a lifting of said heel,
- wherein said sole has a longitudinally extending central groove formed therein for receiving the hook element of the rear retaining element and the rear retaining element of the ski binding in an opened state is pressed upwards from an upper surface of a ski by a measure x, and held in that position, by a spring element.
