Abstract: A safety toe unit for ski binding includes a compensation mechanism to compensate the release setting of the binding for the changes in the frictional resistance to sliding of the ski boot relative to the ski which accompany the continuously changing pressure between the ball region of a skier's foot and the ski. The invention is applicable to most known kinds of safety toe unit and in particular to those safety toe units which feature a safety release mechanism including at least one spring adapted to bias one or more toe clamping elements into a ski boot securing position and operative on the occurrence of a predetermined sideways force to permit sideways pivoting of the toe clamp or at least of an element thereof to a position in which the ski boot is released from the binding.

Abstract: A cross country ski binding having at least one upwardly extending member engaging in a corresponding recess in the toe portion of the sole of a ski shoe and a pair of conically divergent side members and an upper top restraint member to complete the location of the toe portion.Actuating devices are provided for producing relative movement in the longitudinal direction of the binding between the upwardly extending member and the side and top restraint members so that the toe portion can first be inserted over the upwardly extending member and subsequently drawn into engagement with the side and top restraint members. The actuating devices include toggle lever devices, cam track and journal devices, and a gear wheel and gear track device.

Abstract: A toggle lever type cross-country ski binding is provided which includes a retaining element pivotally attached to guide arms hingedly supported on a baseplate fixed to a ski. In operation, the retaining element is movable through a dead-center position between a lifted release position and a lowered in-use position with a hook-shaped projection engaging with a boot sole extension to hold the same against longitudinal movement. To facilitate resilient holding of the boot sole, without the need for additional tension springs in the toggle lever arrangement, various embodiments of the invention are disclosed including resilient longitudinal displaceability of the pivot joints between the guide members and the retaining element or between the retaining element and the sole extension.
