Abstract: A device which connects a rider's boot or boot binding to a snowboard or other gliding board while allowing free rotation of the boot relative to the board during use. The base of the device is rigidly affixed to the board and a mounting disk is secured to the base preventing relative translation in all directions between the base and mounting disk, but allowing rotation of the mounting disk relative to the base about an axis perpendicular to the base. During relative rotation, the base and mounting disk remain in parallel planes. The mounting disk includes provisions to attach the rider's boot or boot binding to the mounting disk. The device employs load-bearing balls, load-bearing rollers and/or load-bearing surfaces. One or more springs or elastomeric materials can be installed, at the option of the rider, between the base and mounting disk to cause the mounting disk to return to a predetermined angular position relative to the base.
