Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of, and priority to, U.S. Provisional Application Ser. No. 61/481,132, filed on Apr. 29, 2011, entitled “Splitboard Binding Apparatus,” which is incorporated herein by reference in its entirety.

FIELD

The present disclosure generally relates to split snowboards, also known as splitboards, and includes the disclosure of binding apparatus and systems relating to, or configured to be used with, a splitboard for converting the splitboard between a snowboard for riding downhill in ride mode and touring skis for climbing up hill in tour mode.

BACKGROUND

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. There are relatively few inventions that provide this basic splitboard functionality.

With the growth of splitboarding in recent years, users seek more functionality similar to alpine touring ski set ups. Alpine touring ski set ups allow a user to skate ski out of flat areas such as cross country trails, forest service roads, frozen lakes, valley bottoms, etc. The ability to lock the heel of the binding down from a free heel configuration has been unique to alpine touring bindings as they are used for alpine skiing with the heel locked down. Splitboarders have attempted to find ways to lock their heels down in tour mode for applications such as skating out of flat areas, traversing, and side stepping. One way users have done this by lashing the heels of their bindings with rope or straps to attachments on the skis. However, this method requires substantial time to set up and still does not provide proper support to the user. Other users have gone away from using snowboard boots and started using ski boots to allow the use of existing alpine touring ski binding technology for the tour mode. The use of such bindings for the tour mode allows a user to tour lock their heels down when desired, but using ski boots for snowboarding is undesirable for many snowboarders. Ski boots typically prevent lateral ankle movements, dorsiflexion of the ankle, and plantarflexion of the ankle. Such constraints take away from the surfy feel of snowboarding. The transition for snowboarders to go from snowboard boots to ski boots is difficult. Additionally, mounting such alpine touring bindings to production splitboards typically involves the use of custom mounting brackets, which add additional weight to the splitboard.

SUMMARY

Some embodiments provide an apparatus for use on a splitboard to convert the splitboard between a ride mode and a tour mode. The apparatus may comprise a binding interface that includes a first attachment portion, a second attachment portion generally opposing the first attachment portion, and a third attachment portion disposed generally between the first attachment portion and the second attachment portion. The binding interface may be configured to removably attach to a ride mode interface of a splitboard in a ride mode configuration and to removably attach to a tour mode interface of a splitboard in a tour mode configuration. The first attachment portion of the binding interface may be configured to engage the ride mode interface to secure a first portion of the binding interface to the ride mode interface. The second attachment portion of the binding interface may be configured to releasably couple a second portion of the binding interface to the ride mode interface such that the first portion of the binding interface generally opposes the second portion of the binding interface. The third attachment portion of the binding interface may be configured to engage more than one interface. In such embodiments, the binding interface securely joins splitboard halves to form a snowboard when the binding interface is attached to the ride mode interface.

In some embodiments, a system for use with a splitboard to convert the splitboard between a ride mode and a tour mode is provided. The system may comprise a binding interface and a heel riser interface. The binding interface may be configured to removably attach to a ride mode interface in a ride mode configuration and to removably attach to a tour mode interface in a tour mode configuration. The heel riser interface may comprise at least one height position configured to raise a user's heels while climbing. At least one component of the heel riser interface may also be configured to selectively lock a heel of the binding interface down when the binding interface is attached to the tour mode interface.

In some embodiments, a heel lock down interface is provided for use with a splitboard binding attached to a tour mode of a splitboard binding apparatus. The heel lock down interface may comprise a heel riser system comprising at least one component. The at least one component of the heel riser system may be configured to lock the heel of the splitboard binding down to a splitboard ski.

DETAILED DESCRIPTION

Embodiments of the present disclosure include binding apparatus and systems for use on, or involving, a splitboard for converting the splitboard between a snowboard for riding downhill in ride mode and touring skis for climbing uphill in tour mode. In some embodiments, a splitboard binding apparatus and/or system can include a binding interface configured to receive a snowboard boot and removably and interchangeably attach to a ride mode interface and a tour mode interface, a ride mode interface for removably attaching the binding interface to the splitboard in a ride mode such that the binding interface is positioned in a snowboard stance, and a tour mode interface for pivotably and removably attaching the binding interface to the separated touring skis of the splitboard in a tour mode such that the binding interface is positioned in a touring stance.

As explained in more detail below, in some embodiments, while in the touring configuration, the binding interface can quickly and easily attach to a heel lock down interface for applications such as skating out of flat areas, traversing, or side stepping.

Existing splitboard systems lack heel lock down capability while alpine touring ski systems have the ability to lock the heel down. With the ability to lock the heel down, users of alpine touring ski gear can skate with less effort by being able to push off of the tips of their skis, using their skis like spring elements to propel them forward. Without the heel locked down, when a splitboarder tries to skate the ski pivots at the tour pivot thus not allowing the user to take advantage of the skis as spring elements to propel them forward with less energy. In addition to skating, a heel lock down allows a user to side step up steep terrain. The tour mode of most splitboards allows the skis' tips to rise with each step to keep them above the snow. Having the tips rise with each step makes it difficult to side step because the skis will not stay perpendicular to the fall line. With the use of a heel lock down a splitboarder can keep their skis perpendicular to the fall line and step up an incline, mountain, or hill more easily.

Major challenges to creating a heel lock down for a splitboard system include at least the following: (1) working within the existing mounting hole patterns on production splitboards; (2) adding the heel lock down without substantially increasing the system weight; (3) creating the heel lock down such that the user can easily engage or disengage the feature; (4) creating a heel lock down that does not add additional mechanical complexity and cost; and (5) and creating a heel lock down interface that does not take away from the overall performance and feel of snowboarding. An example of compromised feel or performance would be using alpine touring ski bindings for the tour mode and heel lock down feature, which requires a user to snowboard in stiff ski boots taking away from the snowboarding feel and performance. Embodiments of the unique designs described herein overcome these numerous challenges by creating features with multiple uses on either the binding interface or other interfaces.

In some embodiments, while in the touring configuration, the binding interface can also quickly and easily attach to a crampon without removing the binding interface from the tour mode interface.

Other splitboard systems on the market typically require removal of the binding interface from the tour mode interface to attach a crampon. The ability to quickly attach the crampon without removing the binding interface from the tour mode interface is very desirable because users can find themselves in icy situations where removal of the binding interface is not feasible or possible. An additional feature of some embodiments of the crampon is that it is fixed to the binding interface allowing it to be used as a boot crampon when the binding interface is not attached to the tour mode interface.

In some embodiments, the binding interface can also quickly and easily attach to a snow shoe without removing the binding interface from a user's boot. This allows the user to quickly and easily transfer from tour mode skis to snow shoes to climb terrain too steep to ascend with splitboard skis in tour mode.

In some embodiments, the binding interface is configured to engage with multiple interfaces of a binding system and/or apparatus. For example, a portion of the binding interface can be configured to engage with more than one interface of the binding system and/or apparatus. In some embodiments, a portion of the binding interface is configured to engage with, or selectively attach to, two or more of a ride mode interface, a tour mode interface, a heel lock down interface, a heel riser interface, a riser and heel lock down interface, a crampon interface, and a snow shoe interface. Advantageously, this allows the binding interface to engage with multiple interfaces of the binding system and/or apparatus by using minimal parts or components, thereby providing a binding interface that is relatively lightweight yet able to quickly and easily engage with different interfaces and provide enhanced functionality.

FIGS. 1 and 2 illustrate an embodiment of a splitboard binding apparatus 10. FIG. 1 shows an embodiment of the splitboard binding apparatus 10 mounted to a splitboard having a first ski 11 and a second ski 12 that when combined as shown can create a snowboard 13. In at least one embodiment, the splitboard binding apparatus 10 can be configured to selectively join the first ski 11 and the second ski 12 of the splitboard and/or allow the user to selectively ride the splitboard in either a ride mode or a tour mode.

According to one example embodiment, the splitboard binding apparatus 10 may include one or more board joining devices with a latch side 16 and a catch side 17 configured to join the first ski 11 to the second ski 12 to form a snowboard 13. The board joining devices with the latch side 16 and the catch side 17 may be connected to the skis 11, 12 and positioned at any point along the length thereof. In one implementation, a first board joining device with the latch side 16 and the catch side 17 can be positioned a distance away from the tips of the skis 11, 12 and a second board joining device with the latch side 16 and the catch side 17 can be positioned a distance away from the tails of the skis 11, 12. In further implementations, the splitboard binding apparatus 10 may include any number of board joining devices with the latch side 16 and the catch side 17 as desired, such as one board joining device with the latch side 16 and the catch side 17 or three or more board joining devices with the latch side 16 and the catch side 17 positioned at any point(s) along the length of the splitboard.

In further implementations, the splitboard binding apparatus 10 can include a nose clip 14 configured to couple the tips of the skis 11, 12 together. The nose clip 14 may be further configured to resist relative movement between the tips of the skis 11, 12 in at least one direction. In yet further embodiments, the splitboard binding apparatus can include a tail clip 15 configured to couple the tails of the skis 11, 12 together and resist relative movement between the tails of the skis in at least one direction. For example, FIG. 1 shows the splitboard in a ride mode configuration where board joining devices with the latch side 16 and the catch side 17 join the first ski 11 and second ski 12 together to form the snowboard 13, and nose clip 14 and tail clip 15 prevent shear movement and/or scissoring of the tips and tails of skis 11, 12.

The splitboard binding apparatus 10 may also include one or more binding interfaces 40 configured to couple to a user's feet and/or boots and selectively attach to one or more additional interfaces of the splitboard binding apparatus 10 in a variety of configurations. In particular, as shown in FIG. 1, the binding interfaces 40 may be configured to selectively attach to one or more ride mode interfaces 30 in a snowboard stance in order to allow the user to operate the splitboard in ride mode. In turn, the one or more ride mode interfaces 30 may be connected to and/or assist in joining the first ski 11 and second ski 12.

As shown in FIG. 2, in further implementations, a user may separate the first ski 11 from the second ski 12 in order to ride the splitboard in tour mode. For example, FIG. 2 illustrates a top view of the splitboard of FIG. 1 in tour mode, wherein the board joining devices with latch side 16 and catch side 17, nose clip 14, and tail clip 15 are uncoupled and the first ski 11 and second ski 12 are separated. In particular, the board joining devices with latch side 16 and catch side 17 may include a buckle element 61 and a hook element 62 that are selectively uncoupled to separate the first ski 11 from the second ski 12 to allow a user to operate the splitboard in a tour mode configuration. In addition, the ride mode interfaces 30 may separate and/or move to facilitate use of the splitboard in tour mode. For example, the ride mode interfaces 30 may include a toe receiving mechanism 31 and a heel receiving mechanism 32.

In further implementations, the binding interfaces 40 can selectively couple to the separated skis 11, 12 in a touring stance. For example, the binding interfaces 40 may pivotally and removably attach to one or more tour mode interfaces 70 connected to the skis 11, 12. Accordingly, the tour mode interfaces 70 may allow the user to operate the skis 11, 12 in a tour mode, such as to ascend a slope or hill.

FIG. 3A illustrates an isometric view of a ride mode interface 30. In one implementation, the ride mode interface 30 can include at least one toe receiving mechanism 31 mounted to either the first ski 11 or second ski 12 and at least one heel receiving mechanism 32 mounted to the other of the first ski 11 or second ski 12. The toe receiving mechanism 31 can be configured to receive, engage, and/or secure a first attachment pin (e.g., first attachment pin 45, which is shown in FIG. 4) and can include a toe pin attachment 33 comprising one or more tabs configured to receive the first attachment pin 45 of a binding interface 40 (also shown in FIG. 4). The toe receiving mechanism 31 can also include an arced slot 34 for mounting to either the first ski 11 or second ski 12. In a further implementation, the arced slot 34 can allow for angular adjustment of the ride mode interface 30 with respect to the splitboard. In further implementations, the toe receiving mechanism 31 can include a seam flange 39 with an opening 301, such as slots configured to receive a pin. The toe receiving mechanism 31 can include a stiffening member 302 to reduce the bending in the toe receiving mechanism 31. The heel receiving mechanism 32 can be configured to include flanges 37 with pin attachments 35, such as slots configured to receive a pin, spaced apart to receive the heel side portion 115 of the binding interface 30. The heel receiving mechanism 32 may also include an arced slot 37 for mounting to either the first ski 11 or second ski 12. In addition, the arced slot 37 can allow for angular adjustment of the ride mode interface 100 with respect to the splitboard. The heel receiving mechanism 32 can include a seam shear tab 38 which extends over the seam between first ski 11 and second ski 12 to prevent scissoring or shear movement between the first ski 11 and second ski 12.

In some embodiments, a seam flange 39 for receiving a portion of the binding interface 40 can also be a separate component from toe receiving mechanism 31 and mounted to ski 11 or 12. The seam flange 39 can also be part of the heel receiving mechanism 32.

FIG. 3B is an isometric view of a second embodiment the ride mode interface 30. Many features are similar and will be given like numbers that are described in FIG. 3A. A toe receiving mechanism 306 can have a shear tab 303. A heel receiving mechanism 307 can have a shear tab 304. In some embodiments, the shear tab 303 of the toe receiving mechanism 306 prevents the first ski 11 from moving upward, while the shear tab 304 of the heel receiving mechanism 307 prevents the second ski 12 from moving upward.

FIG. 4 illustrates an isometric view of the binding interface 40. In one implementation, the binding interface 40 can be configured to receive a user's boot, such as a snowboard boot, and to selectively and removably attach to the ride mode interface 30 and tour mode interface 70. In one implementation, the binding interface 40 can include a heel cup 41, a first side 42, a second side 43, a toe side base portion 44 with a first attachment 45, and a heel side base portion 50 with a second attachment 53. In one embodiment, the first attachment 45 can be a toe pin and the second attachment 53 can be a retractable pin. In addition, the second attachment retractable pin 53 can be configured to slide in and out of heel side base portion 50 to allow for attachment to the pin attachment 35 of the heel receiving mechanism 32.

In particular, FIG. 5A illustrates a detailed view showing the second attachment retractable pin 53 extending out of the heel side base portion 50 of the binding interface 40. Heel side base portion 50 can include a lever 51, shown here in the closed position, where the lever 51 pulls on drive pin 54 which pulls on linkage 55 which pulls on yoke linkage 56 which in turn pushes linkages 53 which extend second attachment retractable pins 53 and yoke linkage 56 also pushes linkage 58 extending a seam pin 52.

FIG. 5B illustrates a detailed view showing the second attachment retractable pin 53 retracted into the heel side base portion 50 of the binding interface 40. The lever 51 is shown in the open position where the lever 51 pushes on drive pin 54 which pushes on linkage 55 which pushes on yoke linkage 56 which pulls on linkages 53 which retract second attachment retractable pins 53 into the heel side base portion 50.

FIG. 5C illustrates a detailed view showing a second embodiment 500 of the heel side attachment 50 of FIG. 4, where certain features described above may not be repeated with respect to this embodiment. Like features may be given like reference numerals. The second embodiment 500 includes an over-center stop 59. When the lever 51 is in the closed position yoke linkage 56 contacts over-center stop 59 which makes it so an increased amount of force is required to open lever 51. FIG. 5D shows the second embodiment 500 with the lever 51 in the open position.

In further embodiments, some or all of the features and components of the binding interface 40 can be integrated into a boot.

FIG. 6A is a perspective view of the binding interface 40 attached to the ride mode interface 30. The first attachment pin 45 of the binding interface 40 engages the pin attachment 33 of the toe receiving mechanism 31. The lever 51 of the heel side base portion 50 of the binding interface 40 is in the closed position with second attachment retractable pins 53 extending through pin attachments 35 of the heel receiving mechanism 32 of the ride mode interface 30 and the seam pin 52 extending through the opening 301 of toe receiving mechanism 31 of ride mode interface 30 preventing the seam between the first ski 11 and second ski 12 from bowing downward. The seam pin 52 of the binding interface 40 can pull up on the seam flange 39 or the ride mode interface 30, thus pulling the binding interface 40 down to the splitboard for a tight fit.

FIG. 6B is a perspective view of the binding interface 40 released from the ride mode interface 30. The lever 51 of the heel side base portion 50 of the binding interface 40 is in the open position as shown in FIG. 5B. The second attachment retractable pins 53 (not shown) and the seam pin 52 retract into the heel side base portion 50 and the second attachment retractable pins 53 disengage from the pin attachments 35 of the heel receiving mechanism 32 of the ride mode interface 30 and the seam pin 52 disengages from the opening 301 of the toe receiving mechanism 31 of the ride mode interface 30. The binding interface 40 can pivot upward about the first attachment pin 45, which is engaged on the pin attachment 33 of the toe receiving mechanism 31 allowing the binding interface 40 to fully disengage from the ride mode interface 30.

FIG. 6C is a perspective view showing the preloading of the binding interface 40 to the snowboard 13 through the ride mode interface 30. The dashed arrows show the components of the bindings interface 40 (e.g., the first attachment pin 45, seam pin 52, and retractable pins 53) pulling the ride mode interface 30 and the connected snowboard 13 up, thus preloading the snowboard 13 to the binding interface 40. The solid arrows show components of the ride mode interface 30 (e.g., the pin attachments 33, seam flange 39, and pin attachments 35) pulling the binding interface 40 down, thus preloading the binding interface 40 to the snowboard 13.

Numerous embodiments of the binding interface removably attaching to the ride mode interface may fall within the scope of the embodiments disclosed herein. For example, components of the binding interface 40 can function on either the toe side portion 44 of the binding interface 40 or the heel side portion 50 of the binding interface 40 without departing from the scope of the embodiments disclosed herein. Similarly, components of the ride mode interface 30 can function on either the toe receiving mechanism 31 or the heel receiving mechanism 32 without departing from the scope of the embodiments disclosed herein.

FIGS. 7A to 7D illustrate various views of an embodiment of a tour mode interface 70. In one implementation, the tour mode interface 70 can include a base portion 75 with recesses 74 configured to receive a pin, such as the first attachment pin 45 of the binding interface 40 (shown, for example, in FIGS. 4, 6A, and 6B). In addition, the tour mode interface 70 can include a slideable clip 71 configured to releasably engage and/or secure a pin received within the recesses 74.

In further implementations, the tour mode interface 70 can include a lever 73 and linkages 72 configured to operate, such as open and close, the tour mode interface 70. For example, a user can operate the lever 73 to engage and disengage the clip 71 to engage and disengage a pin or pins received within the recesses 74. In one implementation, the user can move the lever 73 to a closed position, as shown in FIG. 7A. The lever 73 pushes on the linkages 72 which move the clip 58 forward and capture a pin or pins within the recesses 74. The user can then move the lever 73 to an open position, as shown in FIG. 7B. As such, the lever 73 pulls on linkages 72 which move the clip 58 backward and release the pin(s).

As shown in FIG. 7A, the lever 73 is in a closed position pushing the linkage 72 which pushes the clip 71 forward to engage a pin or pins positioned within the recesses 74. In addition, the clip 58 can allow the pin to rotate within the recesses 74 of the base portion 75 and relative to the tour mode interface 70. For example, and as shown in FIG. 7C, the binding interface 40 can be pivotally connected to the tour mode interface 50 with the first attachment pin 45 resting in the recesses 74 of base portion 75. FIG. 7D shows first attachment pin 45 of binding interface 40 with a sleeved bushing 46. The first attachment pin 45 pivots inside of the sleeved bushing 46.

FIGS. 8A to 8E illustrate examples of a first embodiment of a heel lock down interface. FIG. 8A is an isometric view of the binding interface 40 attached to the tour mode interface 70 and a heel lock down 81. FIG. 8B is a detailed view of the heel lock down 81, which can have a pin retaining opening 84 to retain a seam pin 52 of the binding interface 40. In some embodiments, the heel lock down 81 can have a forked opening 83 such that the seam pin 52 can pull out of the pin retaining opening 84 if enough upward vertical force is applied. In some embodiments, the heel lock down 81 can have a pivot 82 to allow the heel lock down 81 to spin and selectively engage the seam pin 52, as shown in FIG. 8D. When the seam pin 52 is not retained by the heel lock down 81, the binding interface 40 can freely pivot on the tour mode interface 70. FIG. 8C shows the seam pin 52 retracted and not retained by the pin retaining opening 84 of the heel lock down 81. FIG. 8E shows a detailed view of heel lock down 81 rotated about the pivot 82, thus allowing the seam pin 52 to not engage the heel lock down 81. In FIG. 8E, the heel lock down 81 is shown rotated about the pivot 82 approximately 90 degrees counter-clockwise compared to the orientation of the heel lock down 81 shown in FIGS. 8B and 8C.

FIGS. 9A to 9C show a second embodiment of a riser and heel lock down interface 90. FIG. 9A is an isometric view of the riser and heel lock down interface 90 and the tour mode interface 70 attached to a first ski 11. FIG. 9B is a detailed view of the riser and heel lock down interface 90, which, in a first implementation, can include a riser base 91 and a first riser 92. In a further implementation, the riser and heel lock down interface 90 can also include a second riser 93. The riser and heel lock down interface 90 can serve a dual purpose as a multiple height climbing riser and a heel lock down. FIG. 9C is a more detailed view of the riser base 91, which can have a forward riser slot 94, a back riser slot 95, a riser support 96, mounting holes 97, a shim 98, and riser retention tabs 101, 102. The first riser 92 and the second riser 93 can be made from round metal wire such as stainless steel, aluminum, titanium, carbon steel, etc. The risers can also be machined, forged, cast, molded, fabricated, etc. from stainless steel, aluminum, titanium, carbon steel, or any number of materials. In some embodiments, the first riser 92 and the second riser 93 can be substantially U-shaped. In other embodiments, the risers 92, 93 may comprise other suitable shapes and configurations.

FIGS. 10A to 10D show the riser and heel lock down interface 90 with the first riser 92 and the second riser 93 in various positions. For example, FIG. 10A shows the risers 92, 93 in a “zero rise position.” In such a configuration, the first riser 92 is substantially horizontal and resting on the first ski 11. A first riser hold down tab 101 provides a light vertical constraint to hold down the first riser 92. The second riser 93 is also substantially horizontal and resting on the first ski 11. A second riser hold down tab 102 provides a light vertical constraint to hold down the second riser 93.
