A ski-binding device for cross-country skis comprising a base plate fastened to a ski, a movable holder element pivoted as a rocker arm with one end of the holder element engaging the front portion of a ski boot and the other end of the element being tensioned by a lever arm with at least one cam lobe pressing upwards on the holder element. The cam lobe is angled at less than 180 DEG from the lever arm. A spring is provided between the pivot point of the holder element and the area in which the holder element engages the front portion of the ski boot. The spring forces the holder element in a rocker arm fashion out of engagement with the ski boot when the tensioning lever arm is released and additionally retains the tensioning lever arm in a trough-shaped depression when the binding is out of engagement with the ski boot. Pins resting in selectively-utilizable boreholes are mounted on the block portion of the base plate for engagement with the front portion of the ski boot from below. Teeth-like projections are provided on the engaging end of the holder element for engaging with the front portion of the ski boot. The end of the tensioning lever arm opposite from the cam lobe is shaped as a handle-grip. The holder element is shaped like a wedge and is hollow with internally reinforcing ribs and a cover. A U-shaped recess is provided in the forward end of the holder element to permit the extension therethrough of the tensioning lever arm. |
