Device providing a connection between a boot binding and a snowboard

An assembly for securing a boot binding to a snowboard and for adjusting the position of the boot binding relative to the snowboard both in translation and rotation, the boot binding including a base plate having a circular opening extending through the base plate, the assembly comprising a circular disk adapted to be removably secured to an upper surface of the snowboard and a ring adapted to be received between the circular disk and the circular opening in the base plate with the circular disk retaining the ring and with the ring retaining the base plate when the assembly is secured to the snowboard, the ring having inner and outer circular circumferential surfaces which are radially spaced apart by a distance which varies circumferentially of the ring to form an eccentric member, both the inner circumferential surface of the ring and an outer circumferential surface of the circular disk being configured to define a plurality of angular positions of locking engagement of the ring relative to the circular disk, and both the outer circumferential surface of the ring and an inner circumferential surface of the circular opening in the base plate being configured to define a plurality of angular positions of locking engagement of the base plate relative to the ring.
