  • Patent number: 5951047
    Abstract: A cable lock is incorporated into the grip of a ski pole, using the base of the grip as a lock housing.

In addition, the cable lock wraps the poles and skis and can attach them to a fixed object. The lock housing covers the mounting of the engaging member to the ski, which prevents tampering while the skis and poles are locked.
