Restraining and longitudinal position adjusting device of a binding for skis

A device for retaining and adjusting the longitudinal position of a binding on a ski permitting mounting in a removable and adjustable fashion on the upper surface of said ski in a selected fixed longitudinal position, the binding including:

• a base plate longitudinally slidably mounted on a support piece interdependent with the ski;
• a lock vertically movable upward and downward, and inversely;
• a biasing system urges the lock from an upper unlocked position towards a lower locked position in which the lock cooperates with the support piece;
• and
• the lock including a retaining projection extending upward which retaining projection defines a transverse hole configured to receive and maintain a transverse position of a transverse stem of a removable unlocking tool to retain the lock in the upper unlocked position.

A device comprising:

• a support piece configured to be mounted to a ski, the support piece defining a slide track and a plurality of teeth;
• a base plate to which a binding is mountable, the base plate being configured to slide in the support piece slide track;
• a lock element defining a plurality of teeth, the locking element being movably mounted in the base plate for movement between a locking position in which the teeth of the lock engage the teeth of the support piece and an unlocked position in which the teeth of the lock are displaced from the teeth of the support piece,
• a biasing assembly which biases the lock element toward the locking position;
• and
• an unlocking key which is configured to move the lock element to the unlocked position and retain the locking element in the unlocked position, the unlocking key including:
• a handle portion,
• a straight elongated stem extending from the handle portion, and
• the elongated portion defining a tapered point at an end opposite the handle portion such that the tapered point cams the lock against the biasing assembly moving the lock teeth out of engagement with the support piece teeth in response to longitudinal force and with continued insertion, the stem holds the teeth out of engagement without a user continuing to apply force to the unlocking key permitting the base plate to be slidably positioned relative to the support piece;
• wherein the lock element defines a hole and the base plate defines a key receiving surface, the key receiving surface and the hole being partially aligned in the locked position such that as the tapered point passes over the key receiving surface and engages the hole and the point cams the lock against the baising assembly.
