The binding apparatus can also include a binding interface configured to receive a boot and selectively attach to a ride mode interface in a snowboard configuration and to a tour mode interface in a ski configuration.
Description
BACKGROUND

1. The Field of the Invention


The present disclosure relates to split snowboards, also known as splitboards, and more specifically to a binding apparatus with a ride mode for joining two skis into a snowboard and a tour mode comprising a free heel binding attached to each ski.


2. The Relevant Technology


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, the user can ride the splitboard like a snowboard down the mountain. In tour mode, the at least two skis of the splitboard are separated and configured with bindings mounted like a cross country free heel ski binding. In tour mode, the user attaches skins to create traction when climbing up a hill. When the 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.


The Voile Split Decision system described in U.S. Pat. No. 5,984,324 to Wariakois was one of the first to give basic splitboard function. While functional, the system has its drawbacks. The binding assembly comprises an aluminum channel to span toe and heel slider blocks. The binding assembly is attached to a standard snowboard binding. The combination of the binding assembly and the standard snowboard binding creates a heavy system. Extra weight in backcountry touring equates to more energy expended by the user. In addition to the heavy weight, in order for the design of Wariakois to be strong enough for typical use the slider blocks and binding assembly channel are sized such that the standard snowboard binding sits five eighths of one inch to three quarters of one inch off of the snowboard. The extra height is referred to as “stack height.” The extra stack height causes a user to over leverage the edge of the snowboard while turning making it difficult for the user to control the snowboard.


U.S. patent application Ser. No. 11/409,860 to Ritter improves upon the Wariakois system by integrating the binding assembly with a standard snowboard binding. The invention of Ritter shares many similar drawbacks with the Wariakois system. Both systems of Ritter and Wariakois take significant time to change from ride mode to tour mode and vice versa. The main reason being the user must remove the snowboard bindings from his or her feet before sliding the binding assembly off of the heel and toe slider blocks. Both systems also require the removal and insertion of pins. Long change over times may lead to the user becoming very cold in extreme winter conditions and may discourage use of the product.


In tour mode, both Ritter and Wariakois require a pin that slides through the toe portion of the binding assembly and the ski binding attached to the separate skis. In order for the pin to be easily removed and inserted, clearance must be added to the holes in the binding assembly and the ski binding. This clearance in the holes leads to slop in the tour mode causing the binding assembly to rattle on the ski binding. While touring in icy or crispy snow conditions, slop between the binding assembly and ski binding leads to difficulty in holding an edge while traversing. Instead of creating a high edge angle driving forces directly into the edge of the ski, the slop reduces the ski edge angle thus decreasing the leverage a user can apply to the edge of the ski for gripping into icy snow.


In ride mode, the interference slip fit of the slider blocks and binding assemblies of the Ritter and Wariakois systems are very susceptible to problems from manufacturing tolerances and wear. The design requires a very tight tolerance for the binding assembly channel to slide over the slider blocks. If the slider blocks fit too tight to the binding assembly channel, the user cannot slide the binding assembly channel over the slider blocks without modifying the slider blocks with a knife or file. If the slider blocks fit too loosely to the binding assembly channel, then the bindings can rattle while riding leading to an unresponsive and unsafe ride down the hill.


The conjoining apparatus for holding the skis together for the Warakois system is a set of interlocking hooks. This mechanism requires a net fit on the hooks for the skis to be held together tightly to form a snowboard. If manufacturing tolerances are slightly off on either the hooks or the skis or if the hooks wear down, the splitboard will be held loosely together causing the splitboard to rattle and come apart while riding.


Another device that provides the basic splitboard function is the Burton Splitboard system U.S. Pat. No. 6,523,851 to Maravetz. Maravetz tries to improve upon Wariakois by eliminating removable loose pins. Maravetz uses an intricate binding interface on the bottom of a snowboard binding to attach and join the splitboard. In normal winter snow conditions, snow can pack into the binding interface causing the attachment to function unreliably. In some cases the binding interface will not attach to the board interfaces and in others the attachment device can become frozen in place. Binding malfunctions such as these can strand a user in the backcountry for hours. Splitboard binding system must function properly in the harshest winter conditions.


The Poacher offered by Atomic Snowboarding also provides basic splitboard function. However, the Atomic Poacher requires a special lever tool to change from ride mode to tour mode and vice versa. Without the lever tool, the Atomic Poacher cannot be changed over. In addition, during change over, the Atomic Poacher turns into many small loose parts before they can be assembled into tour mode or ride mode. Loose parts such as the special lever tool and board clips can easily be lost in the deep backcountry snow leaving the user stranded.


In addition to the loose parts and change over troubles of the Atomic Poacher, its tour mode performs similarly to the Wariakois and Ritter devices. In order for the Atomic Poacher binding interface to attach to the ski bindings in tour mode easily, a substantial amount of clearance is left between the attachment pin and the tour mode interface, leading to the same decrease in the ski's ability to grip in icy snow conditions.

DETAILED DESCRIPTION

The present disclosure provides splitboard binding apparatuses configured for operation with a splitboard. The splitboard apparatus of the present disclosure may have various benefits over prior splitboard systems. For example, embodiments of the present disclosure may provide a splitboard system with a lighter weight and lower stack height than prior splitboard systems. In addition, embodiments of the present disclosure may provide a splitboard binding apparatus that can be easily operated without requiring removal of a user's feet/boots from the bindings. In further embodiments, the splitboard binding apparatus may provide a stiffer tour mode pivot and may ride more like a standard snowboard. In yet further embodiments, the splitboard binding apparatus of the present disclosure may be less susceptible to ice and snow buildup affecting its ease of use.


Several details of the example embodiment are set forth in the following description and corresponding figures. In the description that follows, it is understood that the figures related to the various example embodiments are not to be interpreted as conveying any specific or relative physical dimension, and that specific or relative dimensions related to the various embodiments, if stated, are not to be considered limiting unless future claims state otherwise.


Reference is now made to the Figures, which illustrate various example implementations of the present disclosure. FIG. 1 is a top view of an example 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 implementation, 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 60 configured to join the first ski 11 to the second ski 12 to form the snowboard 13. The board joining devices 60 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 60 can be positioned a distance away from the tips of the skis 11, 12 and a second board joining device 60 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 60 as desired, such as one board joining device 60 or three or more board joining devices 60 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 ride mode where board joining devices 60 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/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 ride mode interfaces 30 may be connected to and/or assist in joining the first ski 11 and second ski 12.


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 60, nose clip 14, and tail clip are uncoupled and the first ski 11 and second ski 12 are separated. In particular, the board joining devices 60 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 tour mode. 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 first latch mechanism 31 and second latch mechanism 32 that are configured to separate and rotate in order to retract away for convenient use of the skis 11, 12 in tour mode.


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 50 connected to the skis 11, 12. Accordingly, the tour mode interfaces 50 may allow the user to operate the skis 11, 12 in a tour mode, such as to ascend a slope.


Reference is now made to FIGS. 3A-3B, which illustrate the ride mode interface 30 of FIGS. 1-2 in more detail. In particular, FIG. 3A illustrates a detailed isometric view of one of the ride mode interfaces 30 shown in ride mode (see FIG. 1 for ride mode). In one implementation, the ride mode interface 30 can include a first latch mechanism 31 rotatably attached to the first ski 11 with a screw 34 and second latch mechanism 32 rotatably attached to the second ski 12 with a screw 34. The first latch mechanism 31 and second latch mechanism 32 can be further configured to connect to a binding interface to allow a user to operate the splitboard in ride mode. In additional implementations, the first latch mechanism 32 and second latch mechanism 32 may also resist separation of and/or relative movement between the first ski 11 and second ski 12 when the splitboard is in ride mode.


In one implementation, the first latch mechanism 31 can include a locking mechanism 35 configured to assist in connecting and securing a binding interface to the ride mode interface 30. In one implementation, the locking mechanism 35 may be adjustably coupled to the first latch mechanism 31 through arced slots 38. The arced slots 38 may allow for angular adjustment of the ride mode interface 30. In particular, angular adjustment of the locking mechanism 35 may produce a corresponding angular adjustment of a binding interface with respect to the ride mode interface 30 and/or splitboard, thereby allowing a user to achieve a desired stance angle. In addition, the locking mechanism 35 can include a vertical stop 36, a cam lever 37, and/or positioning elements 39.


In additional implementations, the second latch mechanism 32 can include a binding interface attachment 33. The binding interface attachment 33 may be any member configured to stabilize, receive, abut, and/or connect to any portion of a binding interface to facilitate attachment of the binding interface 40 to the ride mode interface 30. In particular, the binding interface attachment 33 can include a base portion couple to the second latch mechanism 32 and one or more tabs extending away from the base portion and configured to receive, retain, stabilize, and/or connect to a portion of the binding interface 40. In some implementations, the binding interface attachment 33 may be coupled to the second latching mechanism 32 through arced slots allowing for angular adjustment of the ride mode interface 30. In particular, a user may angularly adjust the binding interface attachment 33 as desired and/or corresponding with angular adjustments of the locking mechanism 35 to produce the desired stance angle with respect to the splitboard.


In an additional implementation, each latch mechanism 31, 32 can have a substantially semi-circular shape with a rounded circular edge, adjacent to which the locking mechanism 35 and/or binding interface attachment 33 may be respectively positioned, and an opposing edge configured to abut the other latch mechanism 31, 32. In further implementations, the abutting edges of the latch mechanisms 31, 32 can be configured with corresponding features to improve the abutment of and resist relative movement between the latch mechanisms 31, 32. For example, the abutting edge of each latch mechanism 31, 32 can include a plurality straight portions angled with respect to each other and configured to couple with and abut corresponding portions of the abutting edge of the other latch mechanism. In additional implementations, each latch mechanism 31, 32 may include one or more tabs configured to insert into and be received by corresponding recesses within the other latch mechanism 31, 32 in order to resist relative upward and downward movement between the latch mechanisms 31, 32. In addition, the latch mechanisms 31, 32 may include other features configured to engage together. When the latch mechanisms 31, 32 engage together, as shown in FIG. 3A, they can create a substantially circular mounting interface for the binding interface 40 to mount to.


When a user desires to transition the splitboard to a tour mode, the user can disengage the latch mechanisms 31, 32 and rotate the latch mechanisms 31, 32 apart, as shown in FIG. 3B.


Reference is now made to FIG. 4A, which illustrates a top view of the binding interface 40. The binding interface 40 can include a heel cup 41 and a heel side base portion 42 configured to receive and support the heel portion of a user's boot. In addition, the binding interface 40 can include a first side 46 and a second side 43. In one implementation, the second side 43 can include a second attachment locking portion 44. For example, the second attachment locking portion 44 may comprise a substantially flat flange extending away from the first side 43 of the binding interface 40 and including a slot configured to receive the locking mechanism 35 of the ride mode interface 30. The second attachment locking portion 44 may also include positioning cut outs 45 configured to receive corresponding positioning elements 39 of the locking mechanism 35 in order to achieve correct positioning of and resist relative movement between the binding interface 40 and the ride mode interface 30.


In further implementations, the first side 46 of the binding interface 40 may include a first attachment pin 47. In particular, the first attachment pin 47 may comprise a substantially cylindrical elongate member positioned along the length of and connected at a plurality of points to the binding interface 40. In addition, the first attachment pin 47 may be configured to be received, retained, and/or stabilized by the binding interface attachment 33 of the ride mode interface 30. In addition, the first attachment pin 47 may be configured to be at least partially rotatable relative to the binding interface attachment 33 and/or ride mode interface 30.


The binding interface 40 can also include a toe side base portion 48 configured to at least partially support the front of a user's boot. In addition the binding interface can include a toe pin 49 attached to the toe side base portion 48 and configured to selectively and rotatably couple to the tour mode interface 50 of the splitboard.


Accordingly, the binding interface 40 can be configured to receive a user's boot, such as a snowboard boot, and removably attach to the ride mode interface 30 and removably and pivotally attach to tour mode interface 50 as desired to allow a user to selectively operate the splitboard in either a ride mode or tour mode.


Reference is now made to FIG. 4B, which illustrates an isometric exploded view of the binding interface 40 and ride mode interface 30. As shown, a user can position the binding interface 40 over the ride mode interface 30 in preparation to couple the binding interface 40 to the ride mode interface. As showing, the user can move the binding interface locking mechanism 35 of the ride mode interface 30 to a first position configured to receive the second attachment 44 of the binding interface 40.


Reference is now made to FIG. 4C, which illustrates an isometric view of binding interface 40 mounted to ride mode interface 30. In one implementation, a user may mount the binding interface 40 to the ride mode interface 30 by engaging the first attachment pin 47 of the binding interface 40 with the binding interface attachment 33 of the ride mode interface 30. In addition, the second attachment locking portion 44 of the binding interface 40 can engage and be received by the locking mechanism 35 of the ride mode interface 30. Thereafter, the user can move the locking mechanism 35 to a second position to at least partially secure the binding interface 40 to the ride mode interface 30. In particular, the user can rotate the cam lever 37 and vertical stop 36 of the locking mechanism 35 to abut an upper surface of the locking portion 44, thereby resisting release of the locking portion 44 and binding interface 40.


Reference is now made to FIG. 4D, which illustrates an isometric view of binding interface 40 mounted on and further secured to the ride mode interface 30. In particular, as shown in FIG. 4D, a user can move the locking mechanism 35 to a third position to further secure the second attachment locking portion 44 in place. For example, the user can close the cam lever 37 to push the vertical stop 36 downward and lock the vertical stop 36 and locking portion 44 in place. In one implementation, closing the cam lever 37 can apply pressure to the second attachment locking portion 44 with the vertical stop 36 in order to further secure the binding interface 40, thereby substantially reducing any “play” between the binding interface 40 and ride mode interface 30 and forcing heel side base portion 42 and toe side base portion 48 of binding interface 40 against the snowboard 13.


In like manner, a user may release the binding interface 40 by opening the cam lever 37 of the locking mechanism and moving the locking mechanism from the third position to the second position and then to the first position in order to disengage and release the second attachment locking portion 44 and binding interface 40. The user may then retract the binding interface 40 without having to remove the binding interface 40 from the user's boot.


Reference is now made to FIGS. 5A-5F, which illustrate various views of an example tour mode interface 50. FIG. 5A illustrates a transparent isometric view of the tour mode interface 50 with phantom lines illustrating various internal components of the tour mode interface 50. In one implementation, the tour mode interface 50 can include a base portion 59 with recesses 51 configured to receive a pin, such as the toe pin 49 of the binding interface. In addition, the binding interface 40 can include a slideable clip 58 (see also FIG. 5E) configured to releasably engage and/or secure a pin received within the recesses 51. In particular, the clip 58 can include retaining elements 52 configured to engage a pin and a spring tab 57 configured to transfer force and movement to the clip 58 from other components of the tour mode interface 50.


In further implementations, the tour mode interface 50 can include a cam lever 53 configured to operate, such as open and close, the tour mode interface 50. For example, a user can operate the cam lever 53 to engage and disengage the clip 58 to engage and disengage a pin or pins received within the recesses 51. In one implementation, the user can move the cam lever 53 to a closed position, as shown in FIG. 5A, to move the clip 58 forward and capture a pin or pins within the recesses 51. The user can then move the cam lever 53 to an open position, as shown in FIG. 5B, to allow the clip 58 to move backward and release the pin(s).


In addition, the tour mode interface 50 can include a spring 55 configured to provide a backward force to the clip 58. As a result, the spring 55 may bias the clip 58 to an open, disengaging position, as showing in FIGS. 5B and 5D. In further implementations, the force of the spring 55 can be overcome by the cam lever 53 in order to move the clip into a closed, engaging position, as shown in FIGS. 5A and 5C.


In a yet further implementation, the tour mode interface 50 can include a locking feature 54 configured to resist the cam lever 53 from being inadvertently opened after being closed. In particular, the base portion can include a locking feature configured to engage the cam lever 53 when in a closed position. In addition, the cam lever 53 can include a boss feature 56 configured to engage with the locking feature 54 when in the closed position. In one implementation, in order to release the cam lever 53, the user may be required to lift up on the cam lever 53 to disengage the locking feature 54, thereby releasing the cam lever 53 to be opened.


As shown in FIG. 5A, the cam lever 53 is in closed position pushing the clip 58 forward to engage a pin positioned within the recesses 51. In addition, the clip 58 can allow the pin to rotate within the recesses 51 of the base portion 59 and relative to the tour mode interface 50. For example, and as shown in FIG. 5F, the binding interface 40 can be pivotally connected to the tour mode interface 50 with the toe pin 49 resting in the recesses 51 of base portion 59.



FIG. 5C illustrates a cross-sectional side view of the tour mode interface 50 with the cam lever 53 in the closed position. As shown, in one implementation, the cam lever 53 pushes the clip 58 such that retaining elements 52 become positioned over the recesses 51 of the base portion 59 to engage a pin or pins within the recesses 51 and create a pivotal attachment between the tour mode interface 50 and binding interface 40.



FIG. 5D illustrates a cross-sectional side view of the tour mode interface 50 with the cam lever 53 in an open position. As shown, in one implementation, the cam lever 53 disengages the clip 58 allowing spring 55 to extend pushing on the spring tab 57 of the clip 58 and moving the clip 58 backward and moving the retaining elements 52 away from the recesses 51 of base portion 59, thereby disengaging and/or releasing a pin or pins within the recesses 51. As a result, a user may, for example, release the toe pin 49 of the binding interface 40 and remove the binding interface 40 from the tour mode interface 50.



FIG. 5E illustrates an isometric view of the slideable clip 58 comprising the retaining features 52 and the spring tab 57.


Reference is now made to FIGS. 6A-6C, which illustrate an example board joining device 60. In particular, FIG. 6A illustrates an isometric view of the board joining device 60. As shown, the board joining device 60 can include a buckle element 61. In one implementation, the buckle element 61 can include a cam 63, loop 64 coupled to the cam 63, and a base including a shear tab 65. In addition, the board joining device can include a hook element. In one implementation, the hook element 62 can include a hook 67 and base including a shear tab 66.


In one implementation, the hook element 62 can attach to the first ski 11 and the buckle element 61 can attach to the second ski 12. In a further implementation, a user can join the skis 11, 12 by engaging the hook element 62 with the buckle element 61. In particular, when the loop 64 of buckle element 61 engages the hook 67 of hook element 62 and the cam 63 is in the over-center position, defined by the pivot point 69 of loop 64 being below the pivot point 68 of cam 63, the first ski 11 and second ski 12 can be joined to create snowboard 13 (see e.g., FIG. 1).



FIG. 6B illustrates a top view of the board joining device 60. As shown in FIG. 6b, the shear tab 65 of buckle element 61 can engage the first ski 11 and overlap the seam between the first ski 11 and second ski 12. In addition, the shear tab 66 of the hook element 62 can engage second ski 12 and overlap the seam between the first ski 11 and second ski 12. As a result, the shear tabs 65, 66 may assist in preventing scissoring or shear movement of the skis 11 and 12.



FIG. 6C illustrates a side view of the board joining device 60 with the cam 63 lifted to release the loop 64 from the hook 67, thereby allowing the first ski 11 and second ski 12 to be separated (see e.g., FIG. 2).
