Definitions

  • the present invention relates to bindings of a snowboard and, more particularly, to bindings of snowboard that are established to fix the boots on a snowboard deck and operate in the process of winding a wire, respectively.
  • a snowboard is one of the winter sports playing on the snow, with which a user rides on the snow by shifting the center of gravity in a state that two feet are fixed on a deck, differently from the ski where the two feet are fixed on the respective decks.
  • the snowboard 1 comprises a plate type deck 2 extended in the longitudinal direction, boots, not depicted, and bindings 2 for fixing the boots on the deck 2.
  • the bindings 2 having a function for fixing securely the boots on the deck are classified into alpine binding, soft binding, step-in binding, etc.
  • the soft binding most commonly used is to fix soft boots suitable for freestyle snowboarding.
  • the binding 2 is composed of a base plate; a high back fixed rotatably at both ends of the rear of the base plate; a strap established at one side of the base plate and fixing the instep and toe portions of the boot; buckles provided on an end of the strap; and ratchet belts arranged at the other side of the base plate, horizontally to the buckles, to be connected disconnected with the buckles.
  • the toe portion of the boot is fixed securely by inserting the ratchet belt into the buckle and lifting up the handle of the buckle.
  • the conventional binding 2 has some drawbacks in that it take a long time to fix the boot to the binding since the toe portion and the ankle portion of the boot are fixed separately; the respective ratchet belts should be disconnected from the front and back buckles to separate the boot from the binding 2; and the durability of the ratchet belts may be deteriorated by the concentrated loads caused in the repeated processes of connecting and separating the ratchet belts with and from the buckles.
