  • Patent number: 4452467
    Abstract: The invention concerns a ski particularly a touring and/or cross-country ski, with a binding (10) for holding an anterior tongue-shaped extension of the sole of a ski shoe. The binding (10) is formed by a recess (16) provided in the ski body (12) extending in the longitudinal direction of the ski, with a sole latching apparatus (abutments 18, 18'; latching device 20 or locking device 20') for fixing the sole extension and thus the ski shoe in a positively locked and friction-locked manner. The ski binding (10) is thus provided in the ski body (12) in integrated manner, so that no parts protrude above the ski deck area (14). In this way a subsequent mounting of the ski binding (10) is no longer necessary. In addition, the skis can be shipped with the ski binding (10) mounted for conventional skis without binding, tightly packed against each other. Finally, there is no additional friction caused by the ski binding during the cross-country run in somewhat deeper snow.
