Tool-free adjustable binding for sports board
A binding is adapted for coupling footwear, such as a boot, to a sports board. The binding permits easy adjustment of the binding's position on the board, while also allowing for removal of the binding from the board for improved utility of storage or transport. Adjustment, engagement between binding and board, and removal functions may be accomplished without the use of tools or ancillary components. The binding includes a movable coupler element or elements that removably couple to a retaining disc to secure the binding to the retaining disc and the board.
1. A binding for coupling a boot to a sport board, comprising:
a base plate adapted to be secured to the boot, wherein the base plate can be secured to the sports board via a retaining disc positioned on the sports board, the retaining disc being cylindrical, partially-cylindrical, conical, partially conical, or frustoconical in cross-section;
a coupler element to movably couple to the base plate, wherein the coupler element transitions between an engaged state wherein the coupler element provides an interfering engagement between the base plate and retaining disc to prevent the binding from being decoupled from the retaining disc and sports board, and a disengaged state wherein the coupler element is free from the retaining disc such that the binding can be moved independently of the retaining disc and sports board, the disengaged state of the coupler element allowing the base plate to be removed from the retaining disc, wherein the engaged state includes:
(a) a fully engaged state wherein the coupler element provides an interfering engagement between the base plate and retaining disc in a manner that completely prohibits relative movement between the base plate and the retaining disc;
(b) a partially engaged state wherein the coupler element provides an interfering engagement between the base plate and retaining disc in a manner that prohibits the base plate from being removed from the retaining disc but still permits at least some movement between the base plate and the retaining disc; and
a locking member coupled to the coupler element, wherein the locking member transitions between a locked state wherein the coupler element is locked in the engaged state, and an unlocked state wherein the coupler element can freely move between the engaged and disengaged states, the locking member prohibiting the boot from fully entering the binding when the locking member is in the unlocked state, further wherein the binding comprises one or more mechanisms that bias the coupler element toward the engaged state.
2. The binding as in claim 1 , wherein the binding can rotate relative to the retaining disc when the coupler element is in the partially-engaged state.
3. The binding as in claim 1 , further comprising a secondary lock coupled to the locking member, wherein the secondary lock transitions between (1) a first state that locks the locking member in the locked state, and (2) a second state that permits the locking member to move between the locked and unlocked state.
4. The binding as in claim 3 , wherein the secondary lock connects the locking member to the coupler element wherein the secondary lock comprises a rotating element positioned in such a way that an engagement surface between the secondary lock and either the locking member or the coupler element is created when the locking member is in the locked position.
5. The binding as in claim 1 , wherein the locking member provides an indicator that deters a user from attempting to secure the boot to the binding when the locking member is in the unlocked state.
6. The binding as in claim 1 , wherein the locking member cannot be moved from the locked state to the unlocked state when the boot is secured to the base plate.
7. The binding as in claim 1 , wherein movement of the locking member causes movement of the coupler element between the engaged and disengaged states.
8. The binding as in claim 1 , wherein the coupler element moves in a sliding motion as it transitions between the engaged and disengaged states.
9. The binding as in claim 1 , wherein the coupler element is a pad slidably disposed on the base plate.
10. The binding as in claim 1 , wherein the locking member is a lever pivotably mounted on the base plate, wherein ends of the locking member are coupled with the coupler element.
11. The binding as in claim 1 , wherein the retaining disc is conical, partially conical, or frustoconical in cross-section.
12. A binding for coupling a boot to a sport board, comprising:
a base plate adapted to be secured to the boot, wherein the base plate can be secured to the board via a retaining disc positioned on the board, the retaining disk being partially-cylindrical, conical, partially conical, or frustoconical in cross-section; and
an orifice at least partially defined by the base plate, the orifice adapted to receive the retaining disc, wherein a size of the orifice can be adjusted so as to decrease the size of the orifice to a size that achieves a locked engagement between the base plate and the retaining disc; and
a locking member coupled to the base plate, wherein the locking member can transition to a state that locks the size of the orifice so that the retaining disc is secured to the base plate,
wherein the retaining disc has an annular slot, further wherein both the base plate and the coupler element each have a lip, which engages the annular slot in a fully engaged state and in a partially engaged state, whereas the lips are free from the slot in a disengaged state, further wherein the retaining disc comprises teeth arranged above the slot and the base plate and the coupler element have corresponding teeth around the orifice, the teeth of the retaining disc being in contact with the teeth of the base plate and the teeth of the coupler element in the fully engaged state and being out of contact in the partially engaged state and in the disengaged state.
13. The binding as in claim 12 , further comprising a sliding plate or flange that adjusts the size of the orifice.
14. The binding as in claim 12 , wherein the base plate comprises a first base plate portion and a second base plate portion that are slidably coupled to one another for adjusting the size of the orifice.
15. The binding as in claim 14 , wherein the first base plate portion and the second base plate portion are telescopically attached.
16. The binding as in claim 14 , wherein the size of the orifice can be adjusted between at least:
(a) a first size wherein the base plate is completely immobilized relative to the retaining disc;
(b) a second size wherein the base plate cannot be removed from the retaining disc but the base plate can rotate relative to the retaining disc.
17. The binding as in claim 12 , wherein the base plate comprises a bottom plate and a pad positioned atop the bottom plate wherein the pad provides a support surface for a boot.
