Modular binding for sports board
Disclosed is a snowboard binding for coupling a snowboard boot to a snowboard. The binding includes a highback that extends upwardly from a midfoot or heel region of the binding to provide rear support for the boot. In one embodiment, the highback is formed of a plurality of modular components that each can be manufactured of a separate material to collectively provide desired structural characteristics to the highback. The attachment of the highback, its supporting elements and one or more straps to retain the boot within the binding are arranged such that certain attachment points are fixedly connected to each other and thus made to move synchronously when the position of the highback with respect to the binding's base is adjusted.
1. A modular binding for coupling a boot to a sport board, comprising:
a base plate; and
a highback connected to the base plate and adapted to provide support to a rear region of a boot, the highback being pivotably attached to a first attachment location relative to the base plate, the highback comprising at least two modular components, each modular component comprising a separate material such that the modular components collectively provide a structural characteristic to the highback wherein the modular components include:
(a) a lower component attached to the base plate; and
(b) an upper component attached to the lower component such that the upper component extends upwardly from the lower component in a cantilever fashion, wherein the lower component is attached to the upper component at least one connection location located at an upper region of the lower component and a lower region of the upper component, and wherein the at least one connection location permits the upper component to be moved by a user relative to the lower component such that the user can adjust the position of the upper component relative to the lower component; and
a biasing mechanism that is adapted to bias the upper component back toward a default position relative to the lower component after movement of the upper component relative to the lower component wherein the biasing mechanism is a spring; and
an elongated cable attached to a second attachment location on the heel support element and to a third attachment location on a region of the base plate forward of the first attachment location such that the first, second, and third attachment locations collectively define a generally triangular shape when viewed from a side of the binding, wherein the cable limits movement of the heel support element relative to the base plate.
2. A binding as in claim 1 , wherein the highback includes at least three modular components.
3. A binding as in claim 1 , wherein the base plate includes at least two modular components.
4. A binding as in claim 1 , wherein materials from which the modular components are constructed are adaptable to adjust the interface characteristics between the binding and a user's boot.
5. A binding as in claim 1 , wherein the modular components can move relative to one another to permit the size and shape of the highback to be adjusted.
6. A binding as in claim 1 , wherein the lower component is manufactured of a material that is more rigid than the upper component.
7. A binding as in claim 1 , wherein the modular components comprise a lower component, a central component, and an upper component, wherein each component can be manufactured of a different material to meet specific performance or cost requirements.
8. A binding as in claim 1 , wherein the binding includes an adjustment mechanism that synchronously moves two or more binding fitting elements to various positions.
9. A binding as in claim 1 , wherein the upper component can rotate relative to the lower component.
10. A binding as in claim 1 , wherein the upper component can be slidably moved relative to the lower component along a vertical axis.
11. A binding as in claim 1 , wherein a user can adjust the position of the upper component relative to the lower component in upward-downward or side-to-side directions.
12. A binding as in claim 1 , wherein the upper component can move relative to the lower component in response to an external force on the highback.
13. A binding as in claim 5 , wherein the modular components are adapted to move from a first relative position to a second relative position during the use of the binding, and wherein the modular components remain in the second relative position after movement.
14. A binding as in claim 5 , further comprising a deformable bushing or other insert located at the coupling point between modular components for the purpose of allowing a predetermined range of motion of one modular component with respect to another.
15. A binding as in claim 9 , wherein the upper component rotates about the connection location.
16. A binding as in claim 10 , wherein the upper component can be slidably moved relative to the lower component along a horizontal axis.
17. A binding as in claim 10 , wherein the upper component can be slidably moved relative to the lower component along a horizontal axis and a vertical axis.
