  • Patent number: 4613150
    Abstract: A toe binding for a cross country ski includes a rectangular plastic block for mounting on the ski, with a T-shaped groove in the top of the block for receiving a similarly shaped toe piece. One end of the toe piece is molded into or otherwise permanently attached to the sole of a cross country ski boot, the T-shaped front end of the toe piece extending forwardly. The toe piece is retained in the block by pins slidably mounted in the block for intersecting the groove above the toe piece. The pins are biased across the groove by a leaf spring, and can be moved out of the groove by a handle connected to the spring and pivotally connected to the block by a lever, the handle having a notch for receiving the tip of a ski pole, whereby the handle, lever, spring and pins can be moved.
