This invention provides a user the functionality of a snowshoe while wearing snowboard bindings that secure the user to a snowboard. The invention further provides a quick-disconnect and rapid reconnect to the snowboard. The snowshoe function prevents the user from sinking in fresh or deep snow (i.e., “powder”) while disconnected from the snowboard.
Snowboard riders often encounter situations where they must detach their boots from their snowboard. Often, these situations require the rider to walk through deep, powdery snow. This deep, powdery snow is difficult for a snowboard rider to walk through. Snowboarders who often travel off-piste in the backcountry frequently encounter deep, powdery snow. It is typical for such snowboarders to bring a set of snowshoes. Snowboarders must typically disconnect their boots from their snowboard bindings to use snowshoes. Snowshoes provide the necessary flotation for a user to walk on or near the top of deep powdery snow. A device that doubles as a part of a snowboard binding and a snowshoe would be advantageous to snowboard riders.
The examples described herein will be understood more fully from the detailed description given below and from the accompanying drawings, which, however, should not be taken to limit the application to the specific examples, but are for explanation and understanding only.
Embodiments described herein are related to an expandable snowshoe attachment device for snowboard bindings.
Snowshoes are used to provide flotation to a user when walking across deep, powdery snow. Flotation is required so that a user does not sink deep into the snow. Without the aid of a pair of snowshoes, a person walking across deep, powdery snow will struggle, which may pose a danger of the person becoming stuck or exhausted. Cold winter ambient temperatures can then lead to hypothermia, frostbite, or death for a stranded person. Snowshoes allow a user to traverse snowy terrain easily and quickly.
Snowboard bindings secure a user's boot to a snowboard. A snowboard binding must be strong enough to hold the user's boot to the snowboard during demanding maneuvers, but must also be sufficiently light so as not to be a hindrance to the user and the user's riding experience. A snowboard binding must be easily secured and unsecured by the user. Snowboard bindings commonly use straps to secure a user's boot in the binding.
Snowboard bindings are often directly attached to a snowboard by way of multiple screws. A snowboard may have multiple holes in its top surface to receive multiple screws. A baseplate of a snowboard binding may also have multiple holes, through which screws may be threaded, and into the receiving holes of the snowboard. Tightening the screws may securely fasten the snowboard binding to the snowboard. A snowboard binding may commonly be fastened to a snowboard by four screws.
Described herein is a system for securing a snowboard binding to a snowboard. The system for securing a snowboard binding to a snowboard may be an intermediary between the binding and the snowboard. In some embodiments, the system includes an expandable snowshoe attachment device. The expandable snowshoe attachment device may be a snowshoe apparatus.
The system for securing a snowboard binding to a snowboard may include an upper piece and one or more lower pieces. The upper piece may include holes configured to accept fasteners from the baseplate of the snowboard binding. The holes may be threaded and be configured to accept threaded fasteners. The upper piece may be configured to attach to a lower surface of a baseplate of a snowboard binding. One or more lower pieces of the system may attach to the upper surface of the snowboard. The one or more lower pieces may be rails. The one or more lower pieces may be fastened to the snowboard by fasteners. The one or more lower pieces may be fastened to the snowboard by threaded fasteners. The threaded fasteners may utilize the receiving holes that are conventionally included in the snowboard. The one or more lower pieces can be fastened to the snowboard by other fasteners, including nails or adhesives.
The upper piece may be configured to attach to the one or more lower pieces. The attachment of the upper piece to the one or more lower pieces may create a rigid connection between the snowboard binding and the snowboard. The rigid connection between the binding and the snowboard may allow the snowboard rider to have full control over the snowboard without the worry of a loose connection.
The upper piece may include one or more extensions. The one or more extensions may be located at the rear of the upper piece. The one or more extensions may be coupled to the upper piece. The one or more extensions may be substantially planar. The one or more extensions may be retained in a retracted state. The one or more extensions may deploy to increase a bottom surface area of the upper piece. The one or more extensions may slide in a rearward direction to deploy. The one or more extensions may deploy responsive to pressure from one or more springs. In some embodiments, the one or more extensions deploy responsive to pressure from a lever. The lever may be manually operated. The lever may also be spring-activated.
Increasing the bottom surface area of the upper piece may increase the flotation of the upper piece on surfaces such as soft snow. Increasing the flotation of the upper piece on surfaces such as soft snow may allow a user to walk across the soft surface without sinking as deep into the soft surface as he or she would if walking without the upper piece. The upper piece may be used as a snowshoe when it is disconnected from the one or more lower pieces without the need for the user to disconnect his or her boot from the snowboard binding.
In some embodiments, the upper piece may be made up of two or more portions. The upper piece may include an inner portion and an outer portion. In some embodiments, the outer portion comprises two halves which are fastened together. The inner portion and the outer portion may be joined by a pivoting joint. The pivoting joint may pivot on a lateral axis of the upper piece. In some embodiments, the user's snowboard binding is attached to the inner portion of the upper piece. The pivoting joint may allow a user whose snowboard binding is attached to the upper piece to walk with a more natural motion while using the upper piece as a snowshoe. When the user lifts their foot and steps forward, the pivoting joint may allow the rear of the outer portion to pivot downward due to gravity. When the user lowers their foot to the surface he or she is walking on, the outer portion may pivot on the pivoting joint to come into the same plane as the inner portion. In some embodiments, the one or more extensions are attached to the outer portion of the upper piece.
In some embodiments, the user's snowboard binding may be fastened to a disk. The disk may be rotatably attached to an upper surface of the inner portion of the upper piece. The disk may rotate about a vertical axis relative to the inner portion of the upper piece. The disk may lock and unlock so that its rotational position can be held or adjusted. The disk may rotate so that the user can adjust the angle of the user's feet relative to the snowboard. This adjustment may be called the “riding stance.” Upon unlocking, the disk may rotate to an angular position which places the user's foot and snowboard binding in-line with a central longitudinal axis of the upper piece. The disk rotating to a center angle may allow a user's foot to be in-line with the direction of travel while walking with the upper piece attached to the user's snowboard binding.
The upper piece and the one or more lower pieces may be made of aluminum. In some embodiments, the upper piece and the one or more lower pieces are made of plastic. In some embodiments, components of the upper piece and the one or more lower pieces are machined from 6061 aluminum. In some embodiments, components of the upper piece and the one or more lower pieces are machined from 7075 aluminum. In some embodiments, components of the upper piece and the one or more lower pieces are cast or stamped. In some embodiments, components of the system are made from stainless steel. Fasteners and other hardware of the system may be of stainless steel construction. In some embodiments, the fasteners and other hardware of the system are made of nickel-plated stainless steel.
The surfaces of the upper piece and the one or more lower pieces may have a coating. In some embodiments, the coating is an anodizing coating. The surfaces of the upper piece and the one or more lower pieces may be anodized. In some embodiments, the upper piece and the one or more lower pieces are powder coated. In some embodiments, a hydrophobic coating is applied to the upper piece and the one or more lower pieces of the system. The hydrophobic coating may prevent ice and snow accumulation on the system.

The binding-to-disk screws 33a-d may extend through a baseplate of a snowboard binding into receiving holes in the pivoting disk 04. The configuration of the threaded holes of the pivoting disk 04 may be a standard configuration commonly used by standard snowboard bindings.
In some embodiments, the pivoting disk 04 may include a stud on its upper surface. The stud may be an extruded stud. The stud may be fastened to the pivoting disk 04. A lock may be connected to the extruded stud. In some embodiments, the lock is the pivoting disk lock 06. The pivoting disk lock may comprise a center section with one or more radially extending arms. In some embodiments, the pivoting disk lock 06 is substantially planar. The pivoting disk lock 06 may have a thickness. The plane of the pivoting disk lock 06 may be parallel to the plane of the pivoting disk 04. The pivoting disk lock 06 may be secured to the pivoting disk 04 by fastening a snowboard binding. The snowboard binding may ‘sandwich’ the pivoting disk lock 06 onto the pivoting disk 04.
In some embodiments, pivoting disk lock 06 has ridges on a lower surface. The ridges on the lower surface of pivoting disk lock 06 may be locking teeth. The ridges on the lower surface of pivoting disk lock 06 may engage with ridges on an upper surface of pivoting disk 04. The ridges on the upper surface of the pivoting disk 04 may also be locking teeth. The ridges on both the upper surface of the pivoting disk 04 and the pivoting disk lock 06 may be situated circumferentially around the center of either the pivoting disk 04 or pivoting disk lock 06 respectively. In some embodiments, the ridges prevent the rotation of the pivoting disk 04 relative to the pivoting disk lock 06. A user may be able to set his or her “riding stance” by adjusting the rotational position of the pivoting disk 04 relative to the pivoting disk lock 06. The pivoting disk 04 may lock in one or more rotational positions.
The pivoting disk lock 06 may include one or more arms. In some embodiments, the pivoting disk lock 06 includes two arms. The arms of the pivoting disk lock 06 may extend radially from the center of the pivoting disk lock 06. The one or more arms of the pivoting disk lock 06 may extend towards the sides of the device.

The locking rails of an expandable snowshoe attachment system may include locking rails 12a and 12b. The locking rails 12a and 12b may connect the inner housing 01 to a snowboard when the inner housing 01 mates to the locking rails 12a and 12b. In some embodiments, the locking rails 12a and 12b may be attached or otherwise fastened to the top surface of a snowboard. The locking rails 12a and 12b may each include holes for fasteners extending from their top surface to their bottom surface. The holes for fasteners in the locking rails 12a and 12b may be spaced to line up with holes typically included in the top surface of a snowboard for mounting bindings.
The locking rails 12a and 12b may be attached to the snowboard by fasteners. The locking rails 12a and 12b may be fastened to the snowboard by an adhesive. The locking rails 12a and 12b may be fastened to the snowboard by threaded fasteners. In some embodiments, the threaded fasteners are screws. The screws may be locking rail screws 32a, 32b, 32c, and 32d. Each locking rail may be fastened by two locking rail screws each. For example, locking rail 12a may be fastened by locking rail screws 32a and 32b, and locking rail 12b may be fastened by locking rail screws 32c and 32d. The locking rail screws 32a-d may thread into receiving holes in the top surface of the snowboard. The receiving holes in the top surface of the snowboard may be holes that are typically included on a standard snowboard for attaching traditional snowboard bindings. In some embodiments, the locking rails 12a and 12b may be fastened using different combinations of the holes in the top of the snowboard to mount the locking rails 12a and 12b toward the front or back of the snowboard.
Each of the locking rails 12a and 12b may substantially be mirror images of each other. The locking rails 12a and 12b may have fronts that are narrower than their bodies. The locking rails 12a and 12b may have substantially pointed fronts. In some embodiments, the points of the fronts of the locking rails 12a and 12b are rounded. The rears of the locking rails 12a and 12b may be tapered.
The locking rails 12a and 12b may include one or more slots in their side surfaces. In some embodiments, the one or more slots are configured to engage with one or more locking members. The one or more locking members may be locking members of the upper portion of the device. The one or more slots of the locking rails 12a and 12b may be configured to engage with locking arms 09a and 09b (see
The locking rails 12a and 12b may be mounted in pairs to one or more snowboards. Locking rails 12a and 12b mounted to a second or third or fourth (etc.) snowboard may be identical to the locking rails 12a and 12b mounted to the first snowboard. A user may be able to attach the expandable snowshoe attachment device to a pair of rails on multiple snowboards. In some embodiments, multiple pairs of locking rails 12a and 12b mounted to different snowboards allows user interchangeability. A user may be able to detach the expandable snowshoe attachment device from one snowboard and attach the device to another snowboard. A second user may then attach a second expandable snowshoe attachment device to the first snowboard.
The left outer housing 02a and the right outer housing 02b may be joined to the inner housing 01 by a pivoting joint. In some embodiments, the pivoting joint allows the inner housing 01 to pivot in relation to the left outer housing 02a and the right outer housing 02b. The pivoting of the pivoting joint may be along a lateral axis of the device. In some embodiments, the inner housing 01 may pivot relative to the left outer housing 02a and the right outer housing 02b when the device is in a state detached from a snowboard. The inner housing 01 may not pivot relative to the left outer housing 02a and the right outer housing 02b when the device is in a state attached to a snowboard. The pivoting may allow a user of the device to walk in a somewhat normal manner across a snowy or soft surface while the device is attached to the user's snowboard binding and boot.
In some embodiments, the pivoting of the inner housing 01 relative to the left outer housing 02a and the right outer housing 02b allows a user the flexibility of bending the user's knee and ankle while walking. In some embodiments, as the user lifts their foot, and thus the device also, the inner housing 01 remains in a plane roughly parallel to the plane of the bottom of the user's boot. The left outer housing 02a and the right outer housing 02b may pivot so that the rear of the left outer housing 02a and the rear of the right outer housing 02b falls below the plane of the inner housing 01. The deployed one or more extensions attached to the rear of the left outer housing 02a and the right outer housing 02b may touch the surface of the snow as the user lifts their foot. As the user moves their foot forward (i.e., takes a step), the deployed one or more extensions may drag across the surface of the snow. As the user lowers their foot, the left outer housing 02a and the right outer housing 02b may again become approximately coplanar with the inner housing 01. In some embodiments, the inner housing 01, left outer housing 02a, right outer housing 02b, and deployed one or more extensions bear the weight of the user as the user walks across a snowy or soft surface. In some embodiments, the pivoting action allows the device to behave like a snowshoe.
In some embodiments, an expandable snowshoe attachment device includes a pivoting disk support 05. The pivoting disk support 05 may support the pivoting disk 04 (See
