Safety rotatable snowboard boot binding
First Claim
1. A snowboard boot binding attachment device for securing a snowboard boot binding to a snowboard and for permitting angular adjustment of the snowboard boot binding relative to the snowboard, comprising:
- a pair of rigid plates including a circular base plate adapted to be secured to the snowboard and a rotatable plate for receiving the snowboard boot binding to be secured thereto, the rotatable plate being positioned above the base plate and being rotatably connected to the base plate; and
a locking assembly for locking the rotatable plate in selected positions of angular adjustment relative to the base plate and for selectively maintaining the rotatable plate in either a locked mode, in which the rotatable plate is prevented from rotating relative to the base plate or a released mode, in which the rotatable plate is free to rotate relative to the base plate, the locking assembly including a locking ring formed by a plurality of locking holes extending through a circumferential portion of the base plate, an opening extending through the rotatable plate and alignable with the locking holes in the selected positions of angular adjustment, and a locking shaft capable of alternating between a locked position extending through the opening of the rotatable plate into one of the plurality of locking holes in the base plate to retain the rotatable plate in the locked mode wherein rotation of the rotatable plate is prevented, and an unlocked position with the locking shaft retracted from the one of the plurality of locking holes in the base plate to put the rotatable plate in the released mode, thereby permitting angular adjustment of the snowboard boot binding relative to the snowboard, the locking assembly further including a locking base attached to the rotatable plate, a sleeve threadedly received within the locking base, and locking members depending from the sleeve, the sleeve being slidably fitted over the locking shaft and being nonrotatable relative to the locking shaft, the sleeve being rotatable relative to the locking base upon rotation of the locking shaft, and the locking members preventing sliding movement of the locking shaft relative to the sleeve upon selective rotation of the locking shaft for maintaining the locking shaft in the unlocked position and the rotatable plate in the released mode, thereby permitting free rotational movement of the rotatable plate relative to the base plate;
a safety means incorporated in the base plate and the rotatable plate, the safety means capable of limiting the degree of relative rotation therebetween to permit the snowboard boot to turn within a safe limit and prevent the snowboard boot from turning beyond the safe limit, the safety means comprising one of the pair of rigid plates having a groove therein in the shape of an arc of a circle and the other of the pair of the rigid plates having a mating pin protruding therefrom, the pin engaging the groove and thereby limiting the degree of relative rotation of the rigid plates to the degree of the arc of the circular groove.

Abstract
A base plate is secured to any existing snowboard with screws or bolts through holes in the base plate mating with the standard holes in the snowboard. A rotatable plate has a wide groove to receive a standard existing boot binding and the two have circular openings which fit rotatably over a protruding circular guide post on the base plate. A cap plate with mating holes and a protruding bottom circular plate extends through the boot binding and rotatable plate openings to contact the guide post on the base plate with the screws or bolts passing through all the mating holes to the snowboard. An elevated rim around the cap plate fits within a circular groove of the boot binding to allow the boot binding and rotatable plate to rotate relative to the cap plate. A low-friction ring has bottom teeth to fit within the teeth of the boot binding and a top low-friction top surface to contact the cap plate. A two-position locking shaft may be locked with the locking shaft inserted in any of the lock holes in a lock ring around the perimeter of the base plate to secure the boot binding at a desired angle to the snowboard and alternately locked with the locking shaft out of the lock holes so that the binding rotates freely. A spring may bias the locking shaft in the locked position. Alternately a spring biased shaft may be lifted out of the locked position and released to return to the locked position by the force of the spring. The lock ring is elevated above the snowboard to allow the lock holes to drain to prevent icing of the lock holes. A protruding pin from the rotatable plate fits within an arc of a circular groove in the base plate to limit the degree of rotation of the snowboard boot for safety. Springs between the pin and the circular groove may control the rotation therebetween.
