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.
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.
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 Wariakois 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.
Embodiments of the present disclosure include a binding apparatus for use on 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. In at least one embodiment, the splitboard binding apparatus can include at least one board joining mechanism including at least one buckle element to mount to a first ski and at least one hook element to mount to a second ski, the buckle element having a shear tab to engage the second ski and the hook element having a shear tab to engage the first ski to prevent shear movement of the first and second skis when joined with the board joining mechanism.
The binding apparatus can further 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.
The tour mode interface of the binding apparatus can include a base portion configured to engage a toe pin of the binding interface, a slideable clip when in a first position engages the toe pin of the binding interface pivotally attaching the binding interface to the base portion of the tour mode interface and when in a second position disengages the toe pin of the binding interface allowing removal of the binding interface from the tour mode interface.
In one embodiment the ride mode interface can comprise of at least two latch mechanisms with a first latch mechanism rotatably attached to a first ski and a second latch mechanism rotatably attached to a second ski wherein the first latch mechanism rotatably engages the second latch mechanism and the second latch mechanism rotatably engages the first latch mechanism to create a ride mode interface to removably attach to the binding interface. In a further embodiment the ride mode interface can have at least one toe receiving mechanism mounted to a first or second ski and at least one heel receiving mechanism mounted to the other of the first and second skis wherein the toe receiving mechanism is configured to receive the toe attachment of the binding interface and the heel receiving mechanism is configured to receive the heel attachment of the binding interface. The binding interface can comprise a toe attachment mechanism and a heel attachment mechanism for attaching to the ride mode interface. In a further embodiment, at least one of the toe or heel attachment mechanisms can include a retractable pin.

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 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.

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
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

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
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.
