Definitions

  • the present specification relates to a new type of snowboard binding.
  • Snowboarding is a popular winter sport, where a snowboarder rides a board down a snow-covered slope.
  • the board is attached to the snowboarder by snowboard bindings.
  • step-in bindings which requires a boot having dedicated connections which engage with corresponding connections on the snowboard binding
  • strap-in bindings where the user tightens straps around the boot to secure the boot to the snowboard.
  • Step-in bindings require boots adapted to a particular snowboard, which is expensive and inconvenient. Strap-in boots, though, require the user to bend forward or sit down while securing and tightening straps around the upper surface of the user's boots behind the toes and in front of the ankle joint (that is, the instep). The process must be reversed, with the user leaning forward or sitting down, to release the boots from the bindings.
  • Other systems include a bar connected to the highback of the snowboard binding, so that the highback pivots forward when the user introduces their foot into the snowboard binding and presses downwards.
  • US7246811 shows a snowboard binding where the highback and instep strap are closed upon the user inserted their boot, the instep strap being finally tensioned using a locking lever. To open the snowboard binding, the user must release the lever.
  • Another snowboard binding EP 8249421 shows a mechanism where the highback and instep strap close when the user inserts a boot into the snowboard binding, the release of the boot being achieved by the user pulling a lanyard.
  • WO2009066029 shows a snowboard binding system where cords tensioning the strap of the snowboard binding are secured by a clamp or cleat, which requires a good quality cleat if the cord is not to be prone to slippage.
  • US6003893 shows a snowboard binding where the release is effected by the user operating a lever or locking unit as an alternative to operating a pull cord, which is inconvenient. The mechanism also has very little adjustability.
  • the present invention seeks to address these problems and is designed to work with standard snowboard boots.
  • a snowboard binding as defined by claim 1.
  • forward and rear refer to the front and back part of the snowboard binding corresponding to the front and back of a user's foot.
  • laterally outward refers to a direction generally horizontal and generally perpendicular to both the sides of the snowboard binding corresponding to the left and right side of a user's foot.
  • left and right correspond to the left and right side of the snowboard binding 10 and foot/boot as viewed in the figures.
  • the proposed snowboard binding 10 comprises a base plate 20, a highback 30, and strap assembly 35, a tread assembly 40 and a rotation control mechanism 51.
  • the base plate 20 is formed with integral vertical side walls 22, 23.
  • the base plate 20 may be attached to a snowboard using conventional 4-screw system, and will typically include a rotating plate as is known in the art (not here shown).
  • the highback 30 is an upright curved structure, and features two lower lugs each in the form of shaped pulleys 54, 54', which curve forward so that they both lie against and are pivotally joined to the side walls 22, 23.
  • the highback 30 may be formed in plastic or carbon fibre, and include cut-out regions to reduce weight as is known in the art.
  • a highback is often inclined from the vertical, usually leaning forward, and the precise angle may be adjustable as is known in the art.
  • a strap 69 is attached to the top of the highback on its outer side. Made of nylon or kevlar, with an additional grip added at its top, it must be sufficiently rigid and large enough to be easily grasped by hand, even with gloves or mittens.
  • the strap assembly 35 includes a front plate 36 which is shaped to conform to the instep of a user's boot.
  • the front plate 36 is attached to the rest of the snowboard binding 10 by two adjustable straps 38, 39 connected to the lower part of the front plate 36, and by two tension cables 41, 42 attached to either side of the upper part of the front plate 36.
  • Each tension cable is attached to the front plate with an adjustment means to adjust the length (and therefore the ultimate tension) of the cable using adjustment knobs 46, to ensure a comfortable fit. Once the correct length of the tension cables has been set, the adjustment knobs 46 are locked to withstand the strain caused during normal use.
  • the front plate may be fabricated from plastic, carbon fibre or kevlar.
  • the tread assembly 40 includes a compression plate 45 that is configured to lie approximately parallel with the base plate (that is, approximately horizontal).
  • the compression plate 45 is approximately rectangular, with the long sides of the rectangle extending from one side of the binding to the other.
  • the compression plate includes two apertures (only one of which, 47, is clearly visible) through which the screws of the base plate 20 may be reached.
  • the compression plate 45 is supported by a front rod system 43 and a rear rod system 44.
  • the front rod system 43 is a shaped rod having a straight median section which acts as an axle shaft for the front part of the compression plate 45.
  • This median section runs in an elongated bore or channel of the compression plate 45 parallel to the compression plate's edge, and the compression plate is free to pivot around the median section.
  • the section of the channel 49 section is elongated in a direction running from the front to the back of the compression plate, so that the median section of the front rod has sufficient play within the channel to slide forwards and backwards along the compression plate as the compression plate is depressed or elevated when the binding is going from the opened to the closed position, or vice versa.
  • the median section is supported at each either end by two parallel, equal length arm sections. These arm sections each terminate in laterally outward-pointing pivot pins, which each engage with pivot seats in the side walls 22, 23.
  • the arm sections are perpendicular to the median section and the pivot pins, so that the pivot pins lie on an axis parallel to but spaced from the median section.
  • the rear rod system 44 is similarly arranged. It too is a shaped rod, having a straight median section which runs through a channel 52 running the width of the rear part of the compression plate 45, parallel to the rear edge of the compression plate 45 and allowing the compression plate 45 to pivot about the median section.
  • Two similar perpendicular arms are angularly disposed from the median section, each arm terminating in a stub axle that extends laterally. These stub axles are coaxial, and each located in pivot seats in the side walls 22, 23, and extend through the side walls 22, 23 to engage with the rotation control mechanism 51.
  • the rotation control mechanism 51 is located here on the right side of the snowboard binding 10. It is anticipated that a pair of bindings be made of two symmetrical bindings so that the rotation control mechanism of each foot faces inwards in the space between both feet.
  • the rotation control mechanism 51 comprises a shaped pulley 54 (best shown in figures 2 to 4 ), a cammed surface 55, and an enclosed spring 56.
  • the shaped pulley 54 and cammed surface 55 are mounted and torsionally secured on the stub axle of the rear rod system 44, so that the shaped pulley 54 and cammed surface 55 both rotate through whatever angle the stub axle of the rear rod system 44 rotates.
  • the left side of the highback also extends to form a shaped pulley 54' which is similar to that of the shaped pulley 54 on the right side of the highback.
  • the shaped pulleys 54 have an arcuate section 59, and two radial sections 57, 58.
  • the edge of each shaped pulley 54 has a groove which accommodates the tension cable 41, which runs from the front plate, over the shaped pulley 54, and terminates behind the pulley, where it is secured.
  • the cammed surface 55 is connected torsionally and coaxially with the shaped pulleys 54, but on the outside of the right side wall 22.
  • the cammed surface is generally circular in shape, but also includes two flats 61, 62 on its radius.
  • the enclosed spring 56 is a strong compression spring 64 (the position here being indicated, the spring itself not being visible), retained in a housing 65.
  • the housing has an open side, so that the compression spring terminates in a formed head, which can press against and act on the cammed surface 55 through the open side of the housing 65.
  • cammed surface 55 and shaped pulleys 54, 54' are torsionally secured to the stub axle of the rear rod system 44. Rotation of the stub axle of the rear rod system 44 therefore causes the angular rotation of the cammed surface 55 and shaped pulley 54 about the stub axle.
  • the compression plate 45, rear rod system 44 and front rod system 43 together (together with the side walls 22, 23 on which the rear rod system 44 and front rod system 43 are fixed) form a four bar linkage.
  • the other links are thereby constrained to move together.
  • the linkage is so configured that when the snowboard binding 10 is in the open position and the highback 30 is angled backwards, the stub axle of the rear rod system 44 elevates the compression plate 45 above the base plate 20, the front rod system 43 being constrained to elevate the front edge of the compression plate 45.
  • the shaped pulley 54 also rotates by the same angle. Clockwise rotation (in the sense shown in figure 2 indicated by arrow a ) of the shaped pulley 54 causes the surface of the arcuate section 59 of the shaped pulley 54 pull to engage with the tension cables 41. The other end of the tension cable is drawn in the direction of the shaped pulley 54, which in turn draws the front plate 36 likewise.
  • the front plate 36 simultaneously tightens against the instep of the user's boot, reaching its maximum tightness when the compression plate 45 abuts the base plate 20 of the snowboard binding 10.
  • the cammed surface 55 of the rotation control mean 51 also rotates as the stub axle of the rear rod system 44 rotates. While the snowboard binding 10 is in the open position, the midpoint of the first flat 61 is positioned adjacent to the enclosed spring 56, so that the free formed head of the compression spring 64 acts against it the cammed surface 55 at a point where its radius is at a minimum, and the compression spring's extension is at a maximum. The spring therefore acts against any rotation of the cammed surface 55 away from this point, and acts to bring the cammed surface 55 back to this orientation in the absence of a sufficient force to rotate the cammed surface.
  • the compression spring 64 then acts to urge the cammed surface 55 to rotate further until the formed head of the compression spring 64 is acting on the midpoint of the second flat 62.
  • the flats shown here are equal in length, so the biasing force towards the open position and towards the closed position varies symmetrically with angular displacement in either direction from the overcentre point. If a greater biasing force is desired to keep the snowboard binding in the closed position (for example), the cammed surface 55 may be varied to effect this. For example, the length of the flat may be increased, or the shape may be varied to reduce the radius and slope of the cammed surface, such as excising a scalloped shape from the profile of the cammed surface.
  • the longitudinal displacement of the spring (and therefore the force it exerts) can be adjusted using adjustment screw 66. This adjustment must be carried out to take into account the weight and level of the snowboarder, a higher compression being required for heavier and/or better snowboarders. The action of the compression spring, particularly after this adjustment, ensures that the binding does not open accidentally during use.
  • the enclosed spring 56 and the cammed surface 55 of the rotation control mechanism 51 therefore acts to bias the ski boot in either the fully open position, or the fully closed position. Resistance to moving the boot from one position to the other is resisted until the rotation control mechanism 51 overcentres, after which point the boot is then urged to the opposition position.
  • the user steps into the fully open boot (with a movement generally by arrow b), depressing the compression plate 45 as previously described.
  • the force applied by the user's foot overcomes the opposing force of the enclosed compression spring 56, the rotation control mechanism 51 overcentres and acts to close the binding securely around the user's boot, with the highback 30 secured against the user's heel, and the front plate 36 tightly drawn against the user's instep, securing the snowboard to the user.
  • the highback is simply pulled back using strap 69 in the direction generally indicated by arrow e (rotating around the stub axle of the rear rod system 44) with sufficient force to oppose the action of the enclosed spring 56, while simultaneously taking weight off the user's foot, until the rotation control mechanism 51 overcentres, at which point the boot will spring fully open and the user's boot may be lifted out of the snowboard binding 10 with a movement indicated by arrow d.
  • the user can step into the open snowboard binding 10, and the snowboard binding 10 closes and secures the user's feet on the snowboard without having to perform any manual action, or operate any latch mechanism or fastener on the snowboard binding 10, and therefore the user does not have to lean forward or sit down to attach the snowboard binding 10.
  • detachment is a simple process of pulling back on the strap 69 on the highback 30, without the user having to operate any latch or release mechanism. Since the strap will usually be situated close to the back of the knee, the user should be able to open the snowboard binding with a small amount of flexing the knees or bending, without having to sit or crouch.
  • the opening and stepping out process may be carried out by the back foot first, allowing the boarder to keep the front foot attached to the board if needed (e.g. at certain ski lifts), although the front foot may be removed first if desired.
