INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS

Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57.

BACKGROUND

The present disclosure generally relates to split snowboards, also known as splitboards, and includes the disclosure of a touring snowboard boot binding with adjustable leverage devices relating to, or configured to be used with, for example, a splitboard for adjusting posterior leverage for riding downhill in ride mode and adjusting lateral leverage for climbing uphill in tour mode. The present disclosure also includes systems and methods relating to touring snowboard boot binding with adjustable leverage devices.

Splitboards are used for accessing backcountry terrain. Splitboards have a “ride mode” and a “tour mode.” In ride mode, the splitboard is configured with at least two skis held together to form a board similar to a snowboard with bindings mounted somewhat perpendicular to the edges of the splitboard. In ride mode, a user can ride the splitboard down a mountain or other decline, similar to a snowboard. In tour mode, the at least two skis of the splitboard are separated and configured with bindings that are typically mounted like a cross country free heel ski binding. In tour mode, a user normally attaches skins to create traction when climbing up a hill. In some instances, additional traction beyond what the skins provide is desirable and crampons are used. When a user reaches the top of the hill or desired location the user can change the splitboard from tour mode to ride mode and snowboard down the hill.

SUMMARY

Some embodiments provide a touring snowboard boot or binding configured to receive a boot. In some embodiments, the touring snowboard binding can comprise an adjustable lateral leverage device comprising at least one first attachment generally at a top corner of the highback, at least one second attachment on the opposing side of the binding generally at an ankle portion of the boot or binding, an adjustable tensioning element extending diagonally between the at least one first attachment and the at least one second attachment, wherein when the tension in the adjustable lateral leverage device is increased the lateral support to the boot is increased proportionally and wherein when the tension in the adjustable lateral leverage device is decreased the lateral support to the boot is decreased proportionally.

Other embodiments provide a touring snowboard binding configured to receive a boot, the touring snowboard binding comprising at least one base portion, a heel cup, a highback, at least one attachment element for retaining the boot in the binding, an adjustable posterior leverage device, the adjustable posterior leverage device comprising a forward lean piece rotatably adjustable between a first position with minimal posterior support for tour mode and a second position of desired posterior support for ride mode, wherein the second position can be pre-set to a plurality of ride mode posterior support angles, wherein the rotation angle between the first position and second position can be generally about a quarter rotation.

DETAILED DESCRIPTION

Because a splitboard is used to ride as a snowboard down the hill and hike or tour up the hill as skis, a user has different leverage requirements while in “ride mode” than in “tour mode.” A snowboard has a toe side edge and a heel side edge. In order to generally have the same performance turn on the toe side edge and heel side edge, standard snowboard bindings allow a user to provide extra leverage to the heel side edge through the use of a highback. Highbacks have forward lean adjustments to increase or decrease the amount of posterior leverage a user can apply to the heel edge of the snowboard by increasing the support of a user's calf with increased forward lean and decreasing the support of a user's calf with decreased forward lean. Most forward lean adjustments require a number of actions to adjust or they do not provide fine adjustment to achieve the desired forward lean angle. In “ride mode” the user of the splitboard will benefit from positive forward lean on the highback to be able to better leverage the heel side turn. In “tour mode” the user of a splitboard will benefit from negative forward lean on the highback to be able to stride without pressure on the calf. There is a need in the art for a splitboard binding which has the ability to quickly go from a negative forward lean angle to a positive forward lean angle.

In addition to the ability to adjust heel side leverage, splitboarders need the ability to adjust lateral leverage. While in “ride mode” users need to be able to move freely laterally for the ride down the mountain to feel like they are on a normal snowboard. While in “tour mode” users desire lateral leverage, to more easily grip firm or icy snow while touring up the hill. Some splitboarders choose to use stiff snowboard boots or ski boots to achieve this lateral leverage to the detriment of the ride down. Others will use ski boot power straps or utility straps around the top of their highbacks and boots to achieve marginal lateral leverage improvement. Power straps and utility straps around the highback rely on the stiffness of the highback to provide lateral support. The highback will twist and not provide the best lateral support. In addition, the power strap and utility straps need to be attached to use and detached to remove a boot from the binding. There is a need in the art for a splitboard binding or splitboard boot which has the ability to quickly turn lateral leverage on and off.

Turning to the drawings, FIGS. 1 through 6 illustrate an example lateral leverage device 100 mounted to touring snowboard binding 110. Touring snowboard binding 110 is the binding for the right foot of a right and left pair of touring snowboard bindings. The left binding being a mirror image of the touring snowboard binding 110. Touring snowboard binding 110 can include a heelcup 109, highback 107 and ankle strap 105. Ankle strap 105 can be fixed to one side of heelcup 109 at the ankle portion of the binding and releasably attached to the opposing side through ratchet ladder 113 and ratchet 106. Ratchet ladder 113 is attached to heelcup 109 at attachment point 108 at the ankle portion of the binding. Ratchet 106 can detach from ratchet ladder 113 to allow a user to insert or remove a boot from the binding. It is clear to a person of ordinary skill in the art that the snowboard boot and binding can be integrated together. The heelcup and lower portion of the binding can become part of a boot lower. FIG. 43 shows snowboard boot 4300 with binding components integrated.

FIG. 1 shows a side view of an embodiment of a lateral leverage device 100 mounted to touring snowboard binding 110. Lateral leverage device 100 can attach to touring snowboard binding 110 at first attachment 111 on highback 107. First attachment 111 can be any joining device, examples being a screw and nut, press fit component, hook and loop fastener, etc. Lateral leverage device 100 can also attach to touring snowboard binding 110 at second attachment point 104, which can be attached to ankle strap 105 approximately located near ratchet 106. Lateral leverage device 100 can include tension adjustment element 101, tension element 103, and tension element 102. Tension elements 103 and 102 can be made from many materials such as, for example, cable, wire, cord, webbing, flexible plastic, semi-rigid plastic, etc. Lateral leverage device 100 can have many different embodiments, examples of which are further described in FIGS. 1-32.

FIG. 1 further shows an adjustable posterior leverage device 3300 in the tour position as further described in FIGS. 33-42. The combination of the adjustable posterior leverage device 3300 and lateral leverage device 100 gives a splitboarder the unique ability to quickly adjust leverage between a tour mode setting and a ride mode setting.

FIG. 2 further shows an isometric view of an example lateral leverage device 100 mounted to touring snowboard binding 110. Touring snowboard binding 110 has a left side 200 and a right side 201. Lateral leverage device 100 can mount to highback 107 through first attachment 111 on a left side 200 of touring snowboard binding 110. Lateral leverage device 100 can attach can attach to ankle strap 105 on a right side 201 of touring snowboard binding 110. Lateral leverage device 100 can extend diagonally from the left side 200 across to the right side 201 of touring snowboard binding 110.

FIG. 3 shows a top view of lateral leverage device 100 attached to touring snowboard bindings 110 with a snowboard boot 300. Lateral leverage device 100 can be turned on to provide lateral support to snowboard boot 300 as shown in FIG. 3 or lateral leverage device 100 can be turned off to remove lateral support to snowboard boot 300 as shown in FIG. 4. When lateral leverage device 100 is turned on to provide lateral support to snowboard boot 300 tension adjustment element 101 increases tension in tension elements 102 and 103 causing lateral leverage device 100 to tighten around the upper portion 301 of snowboard boot 300. Lateral leverage device 100 prevents lateral ankle flexion of a user by supporting the upper portion 301 of snowboard boot 300.

FIG. 4 shows a top view of lateral leverage device 100 turned off. Tension adjustment element 101 reduces tension in the tension elements 102 and 103 such that the lateral leverage device 100 is slack, removing support to the upper portion 301 of snowboard boot 300 allowing a user to laterally flex their ankle.

FIG. 5 shows a top view of lateral leverage device 100 attached to touring snowboard binding 110 with the straps open to allow for insertion and removal of snowboard boot 300. With the second attachment of lateral leverage device 100 attached to ankle strap 105 near ratchet 106, the lateral leverage device 100 does not need to be detached to insert or remove snowboard boot 300 from the touring binding 110.

FIG. 6 shows a top detailed view of lateral leverage device 100 mounted to touring snowboard binding 110, showing the force flow through lateral leverage device 100. Certain elements have been removed for clarity of description. In some embodiments, lateral force “L” (from upper portion 301 of snowboard boot 300 which is not shown) is applied to lateral leverage device 100 at or around tension adjustment element 101. Lateral leverage device 100 reacts lateral force “L” at first attachment 111 on highback 107 with reaction force R3 and at second attachment 104 on ankle strap 105 with reaction force R4. Reaction force R3 is on the opposite side of line of action “B” of lateral force “L” than reaction force R4 creating a force flow without any reaction moments. Having reaction force R4 on the opposite side of line of action “B” than reaction force R3 allows tension element 102 to generally follow a straight path “D” between adjustable tension element 101 and second attachment 104 limiting the lateral movement of tension adjustment element 101 past neutral position “A”. A more simplified explanation of the force flow of lateral leverage device 100 is described below with respect to FIGS. 14 and 15.

Turning to FIGS. 7-11, the embodiments disclosed herein provide unique advantages over the existing devices of FIGS. 7-11. FIG. 7 shows a top view of a known third strap 700 attached to touring snowboard binding 710. The third strap 700 is attached to highback 711 at attachment points 704 and 705. The third strap 700 is tightened around upper portion 301 of snowboard boot 300 by looping the strap through d-ring 701 and attaching hooks 702 to loops 703. The third strap 700 has been made from nylon webbing or semi-rigid plastic.

FIG. 8 is a detailed top view of the third strap 700 in the neutral position just before lateral force “L” is applied from upper portion 301 of snowboard boot 300. Neutral position “A” shown as a dashed line shows the initial lateral position of the third strap 700. FIG. 9 is a detailed top view of the third strap 700 in the equilibrium position when lateral force “L” from snowboard boot 300 is applied to the third strap 700. Highback 711 twists along path “M” due to the moment induced by lateral force “L”. The third strap 700 is laterally displaced a distance shown as Y1 due to the third strap 700 attempting to align with the line of action “B” of lateral force “L”. The third strap 700 has reaction force R1 at attachment point 704 on highback 711, reaction force R2 at attachment point 705 on highback 711, and reaction force R5 due to the compression of the third strap 700 on upper portion 301 of snowboard boot 300. A simplified explanation of the third strap 700 is set forth below with respect to FIGS. 10 and 11.

FIG. 10 shows a top view of a simplified view of the third strap 700 in the neutral position just before lateral force “L” is applied from upper portion 301 of snowboard boot 300. Dashed line “C” is the plane of the highback 711 which is not shown. The third strap 700 is attached to highback 711 at attachment points 704 and 705. The neutral lateral position of the third strap 700 is shown as dashed line “A”. X0 is the distance between the plane of highback 711 dashed line “C” and the line of action “B” of lateral load “L”. Both attachment points 704 and 705 are on the left side of line of action “B” of lateral load “L”.

FIG. 11 shows a top view of a simplified view of the third strap 700 in the equilibrium position. Snowboard boot 300 is not included in the figure to highlight the lateral translation of the system. The length of the third strap 700 is sized such that it would tightly fit around upper portion 301 of snowboard boot 300. Once lateral load “L” is applied to the third strap 700 it will move to the equilibrium position as shown. The distance between line of action “B” and plane of highback “C” will decrease from X0 to X1. The lateral position of the third strap 700 will move from neutral position “A” by a distance Y1 due to the third strap 700 folding and elongating and highback 711 twisting as shown in FIG. 9. If the third strap 700 is made from a nylon webbing or like material distance Y1 will be the greatest. If the third strap 700 is made from a more rigid material, such as a semi-rigid plastic, Y1 will be slightly decreased due to the amount the third strap 700 can fold on itself, but more torque will be applied to highback 711.

FIG. 12 shows a top view of a simplified view of lateral leverage device 100 as a simple flexible strap, cord or wire. Dashed line “C” shows the plane of highback 107. In the illustrated embodiment, lateral leverage device 100 is attached to highback 107 at first attachment 111 and is attached to heelcup 109 (not shown) at second attachment 104. Second attachment 104 can be attached directly to heelcup 109 or indirectly to heelcup 109 through ankle strap 105 (not shown, see FIG. 1-3). The neutral lateral position of lateral leverage device 100 is shown as dashed line “A”. X2 is the distance between the plane “C” of highback 107 and line of action “B”. First attachment 111 is on the left side of line of action “B” of lateral force “L” and second attachment 104 is on the right side of line of action “B” of lateral force “L”.

FIG. 13 shows a top view of a simplified view of lateral leverage device 100 as a simple flexible strap, cord or wire in the equilibrium position. Snowboard boot 300 is not included in the figure to highlight the lateral translation of the system. The length of lateral leverage device 100 is sized such that it would be tightly fit around upper portion 301 of snowboard boot 300. Once lateral load “L” is applied to lateral leverage device 100 it will move to the equilibrium position as shown. The distance between line of action “B” and plane of highback “C” will marginally decrease from X2 to X3. The lateral position of lateral leverage device 100 will move from neutral position “A” by a distance Y2 due to lateral leverage device 100 will marginally straighten and elongate between second attachment 104 and lateral load “L”. Because first attachment 111 and second attachment 104 are on opposite sides of line of action “B” of lateral load “L” the lateral displacement Y2 is substantially lower than the lateral displacement Y1 of the third strap 700 shown in FIG. 11.

FIG. 14 shows a top view of a simplified view of lateral leverage device 100 with adjustable tension element 101 as a rigid material and tension element 102 as a flexible material. Dashed line “C” shows the plane of highback 107. Lateral leverage device 100 is attached to highback 107 at first attachment 111 and is attached to heelcup 109 (not shown) at second attachment 104. Second attachment 104 can be attached directly to heelcup 109 or indirectly to heelcup 109 through ankle strap 105 (not shown, see FIG. 1-3). The neutral lateral position of lateral leverage device 100 is shown as dashed line “A”. X4 is the distance between the plane “C” of highback 107 and line of action “B”. First attachment 111 is on the left side of line of action “B” of lateral force “L” and second attachment 104 is on the right side of line of action “B” of lateral force “L”. Adjustable tension element 101 as a rigid material extends from first attachment 111 past the line of action “B” of lateral force “L”.

FIG. 15 shows a top view of a simplified view of lateral leverage device 100 with adjustable tension element 101 as a rigid material and tension element 102 as a flexible material in the equilibrium position. Snowboard boot 300 is not included in the figure to highlight the lateral translation of the system. The length of lateral leverage device 100 is sized such that it would be tightly fit around upper portion 301 of snowboard boot 300. Once lateral load “L” is applied to lateral leverage device 100 it will move to the equilibrium position as shown. The distance between line of action “B” and plane of highback “C” will not decrease from X4 to X5, such that X4 approximately equals X5. Y3 is the lateral displacement from neutral position “A”. The lateral position of lateral leverage device 100 will not move from neutral position “A” such that Y3 is approximately zero. In some embodiments, because first attachment 111 and second attachment 104 are on opposite sides of line of action “B” of lateral load “L” and adjustable tension element 101 as a rigid material extends past line of action “B”, tension element 102 cannot elongate when lateral load “L” is applied and the lateral displacement Y3 equals approximately zero.

FIG. 16 is front view of an embodiment of the lateral leverage device 100 in use. Snowboard boot 300 is strapped into touring snowboard binding 110. Touring snowboard binding is attached to ski 1600 in the tour mode position. Ski 1600 is on snow slope 1601 in the side hill position. Lateral leverage device 100 is turned on as described in FIG. 3. Adjustable tension element 101 presses against the upper portion 301 of snowboard boot 300 preventing the ankle of a user, shown as pivot point 1602, from rotating about path M1 allowing the user to attain edge angle theta 1 and greater edge traction between ski 1600 and snow slope 1601 at edge 1603.

FIG. 17 is front view of a snowboard boot 300 strapped into a touring binding without lateral leverage device 100. Touring snowboard binding is attached to ski 1600. Ski 1600 is on snow slope 1601 in the side hill position. Without lateral leverage device 100 the upper portion 301 of snowboard boot 300 has no support, thus allowing a user's ankle 1602 to pivot about path M1 causing the edge angle Θ2 to be less than Θ1 in FIG. 16 reducing edge traction between ski 1600 and snow slope 1601 at edge 1603.

FIG. 18 is a front view of a stick figure splitboarder 1800 on splitboard 1801 with touring snowboard bindings 110. The lateral leverage device 100 is turned off allowing splitboarder 1800 to move freely along path D, fore and aft along the length of the snowboard, while flexing ankles 1602 along paths M1 and M2. Ankle motion is a key element to snowboarding because, for example, ankle motion allows the splitboarder 1801 to absorb terrain, to feel changes in snow conditions, to apply leverage to the snowboard, and to utilize maximum range of motion.

Advantageously, lateral leverage device 100 allows a splitboarder 1800 to attain maximum lateral ankle support while touring, as shown in FIG. 16, and reduce lateral ankle support while snowboarding, as shown in FIG. 18. Lateral leverage device 100 can be adjusted between the on position and off position quickly to allow for ease of use. In FIG. 5, an embodiment is shown where lateral leverage device 100 can attach to touring snowboard binding 110 in such a way that a user can insert or remove their boot from the binding without disconnecting or opening the lateral leverage device 100.

FIG. 19 is a front view of touring snowboard binding 110 with lateral leverage device 100 attached to the highback 107 at first attachment 111 and attached to ankle strap 105 at second attachment 104. Tension element 102 extends diagonally across touring snowboard binding 110 from left side 200 to right side 201. FIG. 20 is a back view of touring snowboard binding 110 with lateral leverage device 100 attached to the highback 107 at first attachment 111.

FIG. 21 is a detailed view of a first embodiment 2100 of lateral leverage device 100. In some embodiments, adjustable tension element 101 has spool 2109 mounted to increase and decrease tension on tension element 103, which is shown as a cable or cord. Tension in tension element 103 is increased by winding tension element 103 onto spool 2109 to decrease the length of cable or cord. Tension in tension element 102 is decreased by unwinding tension element 103 from spool 2109 to increase the length of cable or cord. First attachment 111 can include a cable housing 2111 which tension element 103 routes through. First attachment 111 can also include key hole 2102 and slot 2103. First attachment 111 can further include highback attachment 2110 with shoulder 2101 and pin 2112.

FIG. 21A shows a cross-sectional view of highback attachment 2110. In the illustrated embodiment, shoulder 2101 can slide through key hole 2102 and then slide down slot 2103 to attach to highback attachment 2110. Second attachment 104 can have key hole 2107 and slot 2108. Second attachment 104 can attach to quick attachment 2104 with shoulder 2105, pin 2113, and mounting hole 2106. Shoulder 2105 can slide through key hole 2107 and then slide down slot 2108 to attach second attachment 104 to quick attachment 2104. FIG. 21B is a cross-sectional view of quick attachment 2104.

FIG. 22 is a detailed view of a second embodiment 2200 of lateral leverage device 100. In such an embodiment, adjustable tension element 2201 is a lever driven ratchet. Tension element 2203 is a semi-rigid piece of plastic with first attachment hole 2211 to attach to highback 107. Tension element 2202 is a ladder strap with second attachment 2204.

FIG. 23 is a detailed view of a third embodiment 2300 of lateral leverage device 100. In such an embodiment, adjustable tension element 2301 can be a double d-ring with a first d-ring 2307 and a second d-ring 2305. Tension element 2303 is routed through first and second d-rings 2307 and 2305 such that tension element 2303 is crimped to maintain the desired length. Tension element 2303 can be a piece of webbing with second attachment 2304.

FIG. 24 is a detailed view of a fourth embodiment 2400 of lateral leverage device 100. In such an embodiment, adjustable tension element 2401 is a d-ring with tooth 2407. Tension element 2403 is a semi flexible plastic strap with holes 2406 and first attachment 2411. Tension in lateral leverage device 2400 is adjusted by selecting one of the multiple holes 2406.

Adjustable tension element 2601 has lever 2605 and bale 2606 attached to hook 2607. When lever 2605 is rotated along path “F” the tension in this embodiment 2600 of lateral leverage device 100 increases or decreases in tension. Tension element 2602 can be a semi-rigid plastic strap, a piece of webbing, or a similar element. Sixth embodiment 2600 has first attachment 2611 and second attachment 2604.

FIG. 27 is a side view of a seventh embodiment 2700 of a lateral stiffening device attached to a touring snowboard binding. In such an embodiment, the ankle and toe straps have been removed for clarity of description. FIG. 28 is an isometric view of seventh embodiment 2700.

Base portion 3704 is generally wide to prevent the forward lean block 3301 from rotating along path “K” as shown in FIG. 35 when posterior load is applied to highback 107.

FIG. 38 shows a detailed back view of adjustable posterior leverage device 3300 in the maximum forward lean position. In some embodiments, adjustment piece 3302 is positioned such that pivot screw 3303 is positioned at the top of slot 3700 in the maximum forward lean position 3702. When nut 3801 is tightened on adjustment piece 3302 the teeth 3701 on forward lean piece 3301 and the teeth 4001 on adjustment piece 3302 (see FIG. 40) can grip together to prevent pivot screw 3303 from sliding in slot 3700. FIG. 39 shows a detailed back view of adjustable posterior leverage device 3300 in the minimum forward lean position. In the illustrated embodiment, adjustment piece 3302 is positioned such that pivot screw 3303 is positioned at the bottom of slot 3700 in the minimum forward lean position 3703 (see FIG. 37). When nut 3801 is tightened on adjustment piece 3302 the teeth 3701 on forward lean piece 3301 and the teeth 4001 on adjustment piece 3302 can grip together to prevent pivot screw 3303 from sliding in slot 3700. The ride mode forward lean angle Θ3 as shown in FIG. 34 can be adjusted generally between about 90° and 65° by moving pivot screw along slot 3700 with adjustment piece 3302. In some embodiments, the incremental adjustment of Θ3 is only limited by the tooth size of teeth 4001 and 3701 (e.g., the smaller the teeth the smaller the incremental adjustment angle). The most desirable incremental adjustment angle is around approximately 2°.

FIGS. 41 and 42 are detailed views of adjustable posterior leverage device 3300 mounted to highback 107. Highback 107 can have a mounting surface 4102 which protrudes from highback bottom 4101 to allow the highback to enter the touring position as shown in FIG. 36. In FIG. 41, mounting surface 4102 allows adjustable posterior leverage device 3300 to achieve ride mode angle Θ3 by creating a position such that forward lean piece 3301 can contact heelcup 109. As illustrated in FIG. 42, in some embodiments, highback bottom 4101 allows adjustable posterior leverage device 3300 achieve tour mode angle Θ4 by allowing highback 107 to nest into heelcup 109 and recline back past 90° as shown in FIG. 36 when adjustable posterior leverage device 3300 is rotated as shown in FIG. 35.

Advantageously, adjustable posterior leverage device 3300 allows for a unique ability to quickly adjust between a touring position as shown in FIGS. 35 and 36 and a ride mode position as shown in FIGS. 33 and 34 in one simple movement while being able to set the ride mode position angle Θ3 generally between about 90° and 65°. Other devices require at a minimum two movements to adjust the forward lean positions.
