BINDINGS

TECHNICAL FIELD

[0001] 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.

BACKGROUND

[0002] 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.

DETAILED DESCRIPTION

[0011] Embodiments described herein are related to an expandable snowshoe attachment device for snowboard bindings.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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. [0020] 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.

[0021] 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.

[0022] 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.

[0023] 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. [0024] FIG. l is a schematic diagram illustrating a wireframe top view of an expandable snowshoe attachment device for snowboard bindings, according to certain embodiments. The expandable snowshoe attachment device for snowboard bindings may be an upper piece of a system for securing a snowboard binding to a snowboard. In some embodiments, the expandable snowshoe attachment device is a snowshoe. In some embodiments, the expandable snowshoe attachment device connects a user’s snowboard binding to one or attachment points of a snowboard. In some embodiments, the expandable snowshoe attachment device serves dual roles, the first role being to act as a snowshoe, the second role being to connect a snowboard binding to one or more attachment points of a snowboard. A user may use a pair of expandable snowshoe attachment devices to secure their snowboard bindings to a snowboard (i.e., one device for each snowboard binding).

[0025] The expandable snowshoe attachment device may comprise an inner housing 01 and an outer housing. The outer housing may include left outer housing 02a and right outer housing 02b.. The inner housing 01 may be an inner section or an inner portion of an expandable snowshoe attachment device. The left outer housing 02a and right outer housing 02b may comprise an outer section or an outer portion of an expandable snowshoe attachment device. In some embodiments, the left outer housing 02a and the right outer housing 02b are joined by walking pivot stop 17 (see FIG. 5). The left outer housing 02a and the right outer housing 02b may be joined by fasteners. Walking pivot stop 17 may be attached to each of the left outer housing 02a and the right outer housing 02b by one or more fasteners. The fasteners may be threaded. In some embodiments, the fasteners are screws. The screws may be outer housing to walking pivot stop screws 28a and 28b.

[0026] The inner housing 01 may act as a central body of the device. In some embodiments, the inner housing 01 is substantially planar. The inner housing 01 may have a thickness. The inner housing 01 may be substantially flat. The inner housing 01 may serve as the body to which the other components of the device attach. In some embodiments, the inner housing 01 may have a length similar to its width. The width of the inner housing 01 may be wider than the width of the baseplate of a standard snowboard binding. In some embodiments, the inner housing 01 may be wider at its front than at its rear.

[0027] In some embodiments, the left outer housing 02a may be substantially planar. The right outer housing 02b may also be substantially planar. The left outer housing 02a and the right outer housing 02b may be substantially mirror images of each other. The left outer housing 02a and the right outer housing 02b may each have a thickness. The left outer housing 02a and the right outer housing 02b may substantially surround the inner housing 01. The left outer housing 02a and the right outer housing 02b may reside in substantially the same plane as the inner housing 01. In some embodiments, the left outer housing 02a and right outer housing 02b extend laterally from the inner housing 01. The left outer housing 02a and the right outer housing 02b may also extend rearwards from the inner housing 01. In some embodiments, the combination of the left outer housing 02a and the right outer housing 02b may have a ‘horseshoe’ shape. The left outer housing 02a and the right outer housing 02b may not extend forward of the front edge of the inner housing 01.

[0028] The left outer housing 02a may be joined to the right outer housing 02b. In some embodiments, the left outer housing 02a and the right outer housing 02b are joined by walking pivot stop 17. (See FIG. 5). Fasteners may be used to attach the walking pivot stop 17 to each of the left outer housing 02a and the right outer housing 02b. In some embodiments, the fasteners are screws. In this specific embodiment, the fasteners are walking pivot stop screws 28a and 28b. The walking pivot stop 17 may limit the pivoting range of the left outer housing 02a and right outer housing 02b relative to the inner housing 01. The walking pivot stop 17 may limit the left outer housing 02a and the right outer housing 02b from pivoting to an angle where the rear of the left outer housing 02a and the right outer housing 02b is higher than the rear of the inner housing 01. The planar resting position of the inner housing 01 is substantially parallel to the plane of a surface of the snowboard when the device is attached to the snowboard.

[0029] In some embodiments, a magnetic contact is included between a heel edge of the inner housing 01 and the walking pivot stop 17. The magnetic contact may aid in connecting the inner housing 01 to locking rails of a snowboard (i.e., locking rails 12a and 12b of FIG. 2) by preventing the inner housing 01 and the left outer housing 02a and the right outer housing 02b from pivoting in the way of the locking rails. In some embodiments, the magnetic contact is made of two magnets. In some embodiments, the two magnets are made of magnetic material. The two magnets may be made of a ferrous metal. The magnetic material may be finished with a rubber-coated, powder-coated, or zinc-plated neodymium rare earth magnet.

In some embodiments, the magnetic contact is attached to the device by an adhesive. In some embodiments, the magnetic contact is attached by press-fitting at least a portion of the magnetic contact within a recessed pocket of the walking pivot stop 17. [0030] The left outer housing 02a and the right outer housing 02b may be attached to the inner housing 01 via a pivoting joint. In some embodiments, the left outer housing 02a is attached to the inner housing 01 by way of pivoting dowel 34a and the right outer housing 02b is attached to the inner housing 01 by way of pivoting dowel 34b. The pivoting dowels 34a and 34b may create a pivoting joint between the inner housing 01 and the left outer housing 02a and right outer housing 02b. The pivoting joint between the inner housing 01 and the left outer housing 02a and right outer housing 02b may pivot about a lateral axis of the device. The pivoting dowels 34a and 34b may be retained by inner pivoting dowel brackets 03a and 03b and outer pivoting dowel brackets 03c and 03d (see FIG. 4). Inner pivoting dowel bracket 03 a may be fastened to the inner housing 01 proximate a left side of the inner housing 01. Inner pivoting dowel bracket 03b may be fastened to the inner housing 01 proximate a right side of the inner housing 01. Outer pivoting dowel bracket 03c may be fastened to the left outer housing 02a on an inner side of the left outer housing 02a. Outer pivoting dowel bracket 03d may be fastened to the right outer housing 02b on an inner side of the right outer housing 02b. (See FIG. 4). In some embodiments, inner pivoting dowel brackets 03 a and 03b and outer pivoting dowel brackets 03c and 03d are installed with a side having a smaller surface area facing an upward direction (see FIGS. 1 and 4). In other embodiments, inner pivoting dowel brackets 03a and 03b and outer pivoting dowel brackets 03c and 03d are installed with a side having a smaller surface area facing a downward direction (i.e., inverted from what is shown in FIGS. 1 and 4). A first end of each of the pivoting dowels 34a and 34b may fit in a recess in the inner housing 01. A second end of pivoting dowel 34a may fit in a recess in the left outer housing 02a. A second end of pivoting dowel 34b may fit in a recess in the right outer housing 02b. The pivoting dowel brackets 03a and 34b may cover the recesses in the inner housing 01. The pivoting dowel bracket 03c may cover a recess in the left outer housing 02a. The pivoting dowel bracket 03 d may cover a recess in the right outer housing 02b. (See FIG. 4).

[0031] A disk may be mounted to a top surface of the inner housing 01. The disk may be pivoting disk 04. The pivoting disk 04 may be rotatably attached to a top surface of the inner housing 01. The pivoting disk 04 may be substantially planar. The pivoting disk 04 may have a thickness. The pivoting disk 04 may occupy a plane parallel to the plane of the inner housing 01. In some embodiments, the plane occupied by the pivoting disk 04 is adjacent to the plane of the inner housing 01. The pivoting disk 04 may be supported by the pivoting disk support 05 (see FIG. 4). The pivoting disk 04 may be rotatably attached to the pivoting disk support 05. The pivoting disk 04 may lock at a fixed position with the pivoting disk support 05 by a friction-locked contact when rotated to a center angle. The alignment of the pivoting disk 04 when rotated to a center angle may allow a user’s foot to be in-line with the direction of travel while the user is walking. The pivoting disk support 05 may be attached to the inner housing 01 by one or more mechanical fasteners. In some embodiments, the pivoting disk support 05 is attached to the inner housing by the pivoting disk support screws 23a and 23b. The pivoting disk may be mounted to the approximate center of a top surface of the inner housing 01. In some embodiments, the pivoting disk 04 is substantially circular. The pivoting disk 04 may pivot about a vertical axis. The vertical axis may be approximately central to the pivoting disk 04.

[0032] In some embodiments, the pivoting disk 04 is a connection point for a user’s snowboard binding. The pivoting disk 04 may accept a snowboard binding for attachment. The pivoting disk 04 may include holes for fasteners. In some embodiments, the holes are threaded. In some embodiments, the pivoting disk 04 includes four threaded holes. The holes of pivoting disk 04 may accept binding-to-disk screws 33a, 33b, 33c, and 33d. The binding- to-disk screws 33a-d may be fasteners. In some embodiments, the binding-to-disk screws 33a-d are threaded fasteners. The binding-to-disk screws may be screws. 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.

[0033] 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.

[0034] 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. [0035] 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 arms of the pivoting disk lock 06 may extend past the side edges of the inner housing 01. The arms of the pivoting disk lock 06 may have slots in each arm. The slots may be recessed.

[0036] The slots of the arms of the pivoting disk lock 06 may engage locks. In some embodiments, the locks may be latches. In some embodiments, the latches are draw latches 13a and 13b. Draw latches 13a and 13b may latch the slots of the arms of the pivoting disk lock 06. The draw latch 13a may be attached to an upper surface of the left outer housing 02a by a fastener. The draw latch 13b may be attached to an upper surface of the right outer housing 02b by a fastener. In some embodiments, the draw latches 13a and 13b are attached to the left and right outer housing 02a and 02b respectively each by a rivet. The draw latches 13a and 13b may be attached to the left and right outer housing 02a and 02 b respectively each by a pin. In some embodiments, the draw latches 13a and 13b are each attached to the left and right outer housing 02a and 02b respectively at their outer ends.

[0037] The draw latches 13a and 13b may each include a downward curving lip. In some embodiments, the downward curving lip may engage a slot in an arm of the pivoting disk lock 06. When the device is in a closed and locked configuration, the downward curving lip of each of draw latches 13a and 13b may engage slots of the arms of the pivoting disk lock 06.

[0038] The draw latches 13a and 13b may be spring-loaded. In some embodiments, springs exert pressure on a latch of each of the draw latches 13a and 13b. The springs may exert pressure outwards on a latch of each of the draw latches 13a and 13b. The springs may be within each of the draw latches 13a and 13b. When the draw latches 13a and 13b are released, the springs inside each draw latch 13a and 13b may push on the downward curving lip of each draw latch 13a and 13b toward a position which disengages the draw latches 13a and 13b from the arms of the pivoting disk lock 06. The springs may be coil springs. The springs may be flat springs. The springs may be torsion springs. [0039] The downward curving lip of each of the draw latches 13a and 13b may each engage a fastener. In some embodiments, the fasteners are the locking arm sliding fasteners 31a and 3 lb. (See FIG. 3). The locking arm sliding fasteners 31a and 3 lb may connect to locking arms of the device. The locking arms may be located on a bottom surface of left outer housing 02a and right outer housing 02b. In some embodiments, locking arm sliding fastener 31a connects to locking arm 09a, and the locking arm sliding fastener 3 lb connects to locking arm 09b. (See FIG. 5). The locking arm sliding fasteners 31a and 31b may follow a curved channel in the respective left outer housing 02a and right outer housing 02b. The channels may be “L” shaped. The channels may be concentric to a vertical axis about which each of the draw latches 13a and 13b pivots. The locking arm sliding fasteners 31a and 3 lb may be seated in a key-hole shaped end of each of the channels when the draw latches 13a and 13b engage their respective locking arm sliding fasteners 31a and 3 lb.

[0040] The locking arms 09a and 09b may include a spring. In some embodiments, the springs are locking arm springs 36a and 36b. (See FIG. 5). The locking arm springs 36a and 36b may contact an outer edge of each of the locking arms 09a and 09b. Each of the locking arm springs 36a and 36b may apply an inward force on its respective locking arm 09a and 09b which may disengage locking contact ends of each of the locking arms 09a and 09b from the locking rails 12a and 12b (See FIG. 2) when the draw latches 13a and 13b are disengaged. Locking arm springs 36a and 36b may be flat springs. In some embodiments, locking arm springs 36a and 36b are torsion springs. In other embodiments, locking arm springs 36a and 36b are coil springs.

[0041] In some embodiments, the draw latches 13a and 13b contact the locking arms 09a and 09b respectively when the draw latches are disengaged from the pivoting disk lock 06. The locking arms 09a and 09b may rotate in an outward direction dependent on the rotation of the draw latches 13a and 13b. The locking arms 09a and 09b may each rotate co-dependent with its respective draw latch 13a and 13b. The locking arms 09a and 09b may be free to slide towards a center-inside of each of locking arm guide 10a and 10b (See FIG. 5) when the draw latches 13a and 13b are disengaged from the locking arm sliding fasteners 31a and 31b. [0042] Each locking arm 09a and 09b may include an extension bracket 08a and 08b. (See FIG. 5). Each extension bracket 08a and 08b may be secured in a channel of each locking arm 09a and 09b. The channel may be recessed. In some embodiments, each extension bracket 08a and 08b is secured in its respective channel by locking arm pins 27a and 27b.

(See FIG. 4). In some embodiments, each extension bracket 08a and 08b is secured in it respective channel by two fasteners. The two fasteners may give more rigidity to each extension bracket 08a and 08b. The locking arms pins 27a and 27b may be fasteners. In some embodiments, locking arm pins 27a and 27b are rivets. A forward end of each extensions bracket 08a and 08b may slide freely in the channel of each respective locking arm 09a and 09b. An extruded pin of each of the extension brackets 08a and 08b may ride in the channel of each respective locking arm 09a and 09b. The extruded pin of each of the extensions brackets 08a and 08b may be located on a forward end of each of the extensions brackets 08a and 08b. The extruded pin of each of the extension brackets 08a and 08b may guide the movement of each extension bracket 08a and 08b relative to its respective locking arm 09a and 09b. A rear end of each extension bracket 08a and 08b may each fasten to their respective sliding plate support screws 30a and 30b. (See FIG. 5). Rearward movement of the extension brackets 08a and 08b may force the sliding plate 16 to extend rearward from the body of the device or deploy when the locking arms 09a and 09b are rotated in an outward direction. Forward movement of the extension brackets 08a and 08b may cause the sliding plate 16 to retract when the locking arms 09a and 09b are rotated in an inward direction.

[0043] The inner housing 01 may include a raised portion on its top surface proximate to its front edge. In some embodiments, this raised portion is inner housing lip 07. The inner housing lip may occupy approximately the front width of the inner housing 01. The inner housing lip 07 may extend rearward from the front edge of the inner housing 01. The inner housing lip 07 may be configured to support the toe of a baseplate of a snowboard binding. The inner housing lip 07 may provide support for the toe of a baseplate of a snowboard binding that is attached to the device. The inner housing lip 07 may be subjected to force from the toe of the baseplate of the snowboard binding by the user during snowboarding maneuvers. The inner housing lip 07 may provide stability to the toe of the baseplate of the snowboard binding. In some embodiments, the inner housing lip 07 is fastened to the inner housing 01 by stop screws 24a and 24b. (See FIG. 5).

[0044] The device may include one or more extensions. In some embodiments, the one or more extensions are primary extensions. In some embodiments, the device includes one or more secondary extensions. The one or more secondary extensions may extend from at least one primary extension. In some embodiments, the one or more extensions are plates. The one or more extensions may be coupled to the housing of the expandable snowshoe attachment device. The one or more extensions may extend from the main body of the device to increase a bottom surface area of the device. The one or more extensions may extend responsive to spring action. The one or more extensions may extend responsive to manual operation. In some embodiments, the one or more extensions extend responsive to manual operation with the assistance of spring action.

[0045] The increased bottom surface area of the device may allow the device to function as a snowshoe. In some embodiments, the device includes one extension. In other embodiments, the device includes two extensions. In some embodiments, the extension is sliding plate 16. When the one or more extensions are extended from the main body of the device, the device and the one or more extensions may be in a deployed state. In some embodiments, the one or more extensions extend from the main body of the device in a sliding manner. In some embodiments, the one or more extensions extend from the main body of the device in a rotating manner. The one or more extensions may rotate in a plane substantially parallel to a plane of the main body of the device. When the one or more extensions are in the deployed state, the expandable snowshoe attachment device may be configured to operate as a snowshoe. When the one or more extensions are retracted to the main body of the device, the device and the one or more extensions may be in a retracted state. In some embodiments, the device can be used as a snowshoe in the deployed state. In some embodiments, the device can secure a snowboard binding to a snowboard in the retracted state. In some embodiments, sliding plate 16 deploys by sliding rearward. In some embodiments, sliding plate 16 deploys in a rotational manner.

[0046] Sliding plate 16 may be substantially planar. Sliding plate 16 may have a thickness. Sliding plate 16 may attach to the right portion of the outer housing 02. The sliding plate 16 may be coupled to the left outer housing 02a and the right outer housing 02b. The sliding plate 16 may be attached to the left outer housing 02a and the right outer housing 02b by one or more fasteners. The one or more fasteners may be pins. The one or more fasteners may be screws. The one or more fasteners may extend through the thickness of the left outer housing 02a and right outer housing 02b. In some embodiments, the sliding plate 16 is attached to the left outer housing 02a by sliding plate support screw 30a and to the right outer housing 02b by sliding plate support screw 30b. In some embodiments, sliding plate support screws 30a and 30b are extruded studs of the sliding plate 16.

[0047] In some embodiments, the sliding plate 16 is supported by a pin that rides in one or more channels of an outer housing of the device. In some embodiments, the sliding plate 16 is supported by two pins each riding in an individual channel. In some embodiments, the sliding plate 16 is supported by four pins riding in two separate channels (i.e., two pins in each channel). Supporting the sliding plate 16 by four pins riding in two separate channels may provide more rigidity. The pins may be sliding plate support screws 30a and 30b. In some embodiments, the device includes four sliding plate support screws. In some embodiments, left outer housing 02a includes a channel and right outer housing 02b includes a channel (partially shown in FIG. 1; see also FIG. 5). The channels may be recessed. The channels may be parallel. The sliding plate support screws 30a and 30b may each ride in one of the channels. The sliding plate 16 may deploy responsive to the locking arms 09a and 09b rotating in an outward direction. Each of the locking arms 09a and 09b may contact and push a respective extension bracket 08a and 08b. The pushing of each extension bracket may also push each of the sliding plate support screws 30a and 30b as the locking arms 09a and 09b rotate. The pushing of the extension brackets 08a and 08b and further pushing of the sliding plate support screws 30a and 30b may deploy the sliding plate 16.

[0048] In some embodiments, the sliding plate 16 has a somewhat curved profile. The sliding plate 16 may have a rounded front, with the front of the sliding plate 16 being proximate to where the sliding plate 16 is attached to the left outer housing 02a and the right outer housing 02b. The width of the sliding plate 16 at its center may be a first width as measured in a longitudinal direction of the device. The sliding plate 16 may have a fairly constant width through its center section. The width of the sliding plate 16 may decrease towards its left and right ends. In some embodiments, the shape of the sliding plate 16 is such that the ends of the sliding plate 16 do not extend beyond the outer edges of the left outer housing 02a and right outer housing 02b when the sliding plate 16 is retracted (see FIGS. 6,

7) _·

[0049] In some embodiments, the sliding plate 16 deploys responsive to spring pressure. The sliding plate 16 may deploy responsive to spring action. The sliding plate 16 may be subject to spring pressure while retracted. The sliding plate 16 may be subject to spring pressure while deployed. The spring pressure the sliding plate 16 is subject to while deployed may be less than the spring pressure the sliding plate 16 is subject to while retracted.

[0050] The sliding plate 16 may include a raised portion on a top. The raised portion may be along a rear edge of the sliding plate 16. The raised portion may be a lip. In some embodiments, the raised portion is sliding plate lip 19. The sliding plate lip 19 may be an increased thickness of the sliding plate 16. The sliding plate lip 19 may extend inward from a rear edge of sliding plate 16. The sliding plate lip 19 may provide support for the heel of a baseplate of a snowboard binding that is attached to the device when the sliding plate 16 is in a retracted state. The sliding plate lip 19 may be configured to support a heel of a baseplate of a snowboard binding. The sliding plate lip 19 may be subjected to force from the heel of the baseplate of the snowboard binding by the user during snowboarding maneuvers when the sliding plate 16 is in a retracted state. The sliding plate lip 19 may provide stability to the heel of the baseplate of the snowboard binding when the sliding plate 16 is in a retracted state. [0051] When extended, the sliding plate 16 may extend rearwards from the left outer housing 02a and the right outer housing 02b. The extension of the sliding plate 16 may increase a combined bottom surface area of the device, where the combined bottom surface area of the device includes a bottom surface area of the inner housing 01, a bottom surface area of the left outer housing 02a, a bottom surface area of the right outer housing 02b, and a bottom surface area of the sliding plate 16. Increasing the combined bottom surface area of the device may provide a user with increased flotation when using the device to walk on soft surfaces, such as snow. In some embodiments, it is the increased bottom surface area of the device that allows a user to use the device as a snowshoe.

[0052] When retracted, the sliding plate 16 may retract over the rear portions of the left outer housing 02a, the right outer housing 02b, and the inner housing 01 (see FIGS. 6, 7). When retracted, the sliding plate 16 may not extend beyond the outer edges of the left outer housing 02a and the right outer housing 02b.

[0053] In some embodiments, the inner housing 01 includes a plurality of holes for fasteners to pass through. Fasteners may pass through the inner housing 01 to attach components to the inner housing 01. Some holes in the inner housing 01 include holes for housing locking rail screws 22a, 22b, 22c, 22d, 22e, 22f, 22g, and 22h. The housing locking rail screws 22a-h may fasten housing locking rails 11a, lib, 11c, and 1 Id to the bottom of the inner housing (see FIG. 4). The housing locking rail screws 22a-h may be fasteners. In some embodiments, the housing locking rail screws 22a-h are threaded fasteners. The housing locking rail screws 22a-h may be screws.

[0054] FIG. 2 is a schematic diagram illustrating a wireframe top view of locking rails of an expandable snowshoe attachment system for snowboard bindings, according to certain embodiments. The locking rails of an expandable snowshoe attachment system may be the lower pieces of a system for securing a snowboard binding to a snowboard. In some embodiments, the locking rails connect an upper piece of a system for securing a snowboard binding to a snowboard to a snowboard.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 FIG. 4). In some embodiments, each locking rail 12a and 12b may be engaged by a single locking member. For example, locking rail 12a may engage with locking arm 09a, and locking rail 12b may engage with locking arm 09b. The locking members may engage the one or more slots of the locking rails 12a and 12b tightly to form a rigid connection between the upper portion of the device and the locking rails. In some embodiments, this tight engagement provides a rigid connection between the upper portion of the device and the snowboard.

[0059] 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.

[0060] FIG. 3 shows a schematic diagram illustrating a wireframe side view of an expandable snowshoe attachment device for snowboard bindings, according to certain embodiments..

[0061] 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.

[0062] 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. [0063] FIG. 4 is a schematic diagram illustrating a wireframe bottom view of an expandable snowshoe attachment device for snowboard bindings, according to certain embodiments. An expandable snowshoe attachment device may include dowel caps. In some embodiments, the dowel caps are brackets. In some embodiments, the dowel caps retain pivoting dowels 34a and 34b. The dowel caps may be inner pivoting dowel brackets 03a and 03b, and outer pivoting dowel brackets 03c and 03 d. The inner pivoting dowel brackets 03a, and 03b may be fastened to a bottom surface of the inner housing 01. The outer pivoting dowel bracket 03 c may be fastened to a bottom surface of the left outer housing 02a, and the outer pivoting dowel bracket 03 d may be fastened to a bottom surface of the right outer housing 02b. In some embodiments, the inner and outer pivoting dowel brackets 03a, 03b,

03c, and 03d are be fastened by one or more mechanical fasteners.

[0064] 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 FIG. 1). The pivoting disk support 05 may be attached to an underside of the inner housing 01. At least a portion of the pivoting disk support 05 may protrude through an opening of the inner housing 01 so that the pivoting disk 04 can be rotatably attached to a top surface of the pivoting disk support. In some embodiments, the pivoting disk support 05 is attached to the inner housing 01 by one or more mechanical fasteners. The pivoting disk support 05 may be attached to the inner housing 01 by way of the pivoting disk support screws 23a and 23b (See FIG. 1).

[0065] The underside of the pivoting disk support 05 may include traction-enhancing surfaces. The underside of the pivoting disk support 05 may include a corrugated surface. In some embodiments, the bottom surface of the pivoting disk support 05 includes ridges. The ridges on the bottom surface of the pivoting disk support 05 may aid the user of the device in gaining traction on slick surfaces. The corrugated surfaces may increase traction to the user. The corrugated surfaces may be configured to increase traction of the expandable snowshoe attachment device when operating as a snowshoe. In some embodiments, the pivoting disk support 05 includes crampons or a crampon extending from its bottom surface.

[0066] The pivoting disk support 05 may securely connect the pivoting disk 04 to the inner housing 01. In some embodiments, the pivoting disk support 05 includes one or more embossed grooves on its upper surface. One or more lower extruded studs of the pivoting disk 04 may lock into the one or more embossed grooves of the pivoting disk support 05. In some embodiments, the pivoting disk 04 can freely rotate relative to the pivoting disk support 05. In some embodiments, the rotational relationship of the pivoting disk 04 relative to the pivoting disk support 05 provides a user of the device the ability to adjust riding stance when the device is attached to a snowboard.

[0067] In some embodiments, an expandable snowshoe attachment device includes locking members. The locking members may be locking arms 09a and 09b. The locking arms 09a and 09b may substantially be mirror images of each other. The locking arms 09a and 09b may be attached to the bottom surface of the device. The locking arms 09a and 09b may be attached to the bottom surface of the device near an outside edge. In some embodiments, the locking arm 09a is attached to the left outer housing 02a, and the locking arm 09b is attached to the right outer housing 02b.

[0068] The locking arms 09a and 09b may be attached to the draw latches 13a and 13b respectively by way of the locking arm screws 26a and 26b (see FIG. 5). The locking arm screw 26a may fasten locking arm 09a directly to draw latch 13a. Locking arm screw 26b may fasten locking arm 09b directly to draw latch 13b. In some embodiments, each locking arm 09a and 09b is fixed to its associated draw latch 13a and 13b. Each locking arm 09a and 09b may be fixed to its associated draw latch 13a and 13b by a fastener. A hole may exist in each of the left outer housing 02a and the right outer housing 02b for each of the locking arm screws 26a and 26b to pass through the left outer housing 02a and the right outer housing 02b from each of the locking arms 09a and 09b to their associated draw latch 13a and 13b. The locking arms 09a and 09b may be attached to the locking arm screws 26a and 26b, each at a first distal end.

[0069] The locking arms 09a and 09b may each have a second distal end. Each locking rail 09a and 09b may include a length between its first distal end and its second distal end. In some embodiments, each locking arm 09a and 09b is curved along its length. Each locking arm 09a and 09b may have a hook-shaped second distal end. The second distal end of each locking arm 09a and 09b may be a hook. The hook may be “L”-shaped (see FIG. 5). The “L” or hook of each of the second distal ends of the locking arms 09a and 09b may be oriented to point toward a central axis of the device.

[0070] The locking arms 09a and 09b may each pivot at their first distal ends. In some embodiments, the locking arms 09a and 09b pivot with each of the draw latches 13a and 13b to which they are attached. In some embodiments, each locking arm 09a and 09b pivots so that the second distal end of each locking arm 09a and 09b may engage one or more rails of a snowboard. The second distal end of each locking arm 09a and 09b may engage one or more slots in a rail. The second distal end of each locking arm 09a and 09b may engage a slot of one or more of the locking rails 12a and 12b (see FIG. 2). The second distal end of each locking arm 09a and 09b may hook one or more slots in the one or more rails. In some embodiments, the locking arms 09a and 09b pivot inwards toward a central axis of the device to engage the one or more rails. In some embodiments, the pivoting inwards of the locking arms 09a and 09b creates a tightening motion on the locking rails 12a and 12b. The locking arms 09a and 09b may be in an engaged state when engaging the one or more rails and in a disengaged or open state when not engaging the one or more rails. In some embodiments, the device can be removed from the snowboard when the locking arms 09a and 09b are in a disengaged state. The locking arms 09a and 09b may lock in the disengaged state until the device is placed in position for the locking arms 09a and 09b to engage the one or more rails. FIG. 4 may show the locking arms 09a and 09b in an engaged state. FIG. 5 may show the locking arms 09a and 09b in a disengaged or open state. When the locking arms 09a and 09b are engaged with the one or more slots of the locking rails 12a and 12b, the device may be attached to a snowboard. In some embodiments, the device and the snowboard are in a connected state when the locking arms 09a and 09b are engaged with the one or more slots of the locking rails 12a and 12b. In some embodiments, the device and the snowboard are in a disconnected state when the locking arms 09a and 09b are disengaged from the one or more slots of the locking rails 12a and 12b. In some embodiments, the locking arms 09a and 09b disengage from the one or more slots of the locking rails 12a and 12b responsive to an at least partial rotation of the pivoting disk 04.

[0071] The locking arms 09a and 09b may each be guided by a guide. In some embodiments, each locking arm 09a and 09b is guided by a locking arm guide 10a and 10b. Each locking arm guide 10a and 10b may guide its respective locking arm 09a and 09b as the locking arms 09a and 09b pivot or slide. Locking arm guide 10a may guide locking arm 09a. Locking arm guide 10b may guide locking arm 09b. Each locking arm guide 10a and 10b may be attached to its associated locking arm 09a and 09b. In some embodiments, the locking arm guides 10a and 10b are attached to their associated locking arm 09a and 09b in a manner that allows for a minimal sliding motion relative to their associated locking arm 09a and 09b. [0072] In some embodiments, each locking arm guide 10a and 10b partially encapsulates at least the first distal end of its associated locking arm 09a and 09b. Each locking arm guide 10a and 10b may be substantially “U” shaped. The locking arm guides 10a and 10b may cover a top surface and a bottom surface of each of the locking arms 09a and 09b. In some embodiments, the first distal end of each locking arm 09a and 09b sits in the middle of the “U” of its associated locking arm guide 10a and 10b. [0073] Each locking arm guide 10a and 10b may be subject to spring pressure. In some embodiments, one or more springs exert force on each of the locking arm guides 10a and 10b. In some embodiments, the guide springs 35a and 35b exert force on the locking arm guides 10a and 10b. Guide spring 35a may exert a spring force on locking arm guide 10a. Guide spring 35b may exert a spring force on locking arm guide 10b. In some embodiments, the spring force exerted by the guide springs 35a and 35b on the locking arm guides 10a and 10b is transferred to the locking arms 09a and 09b through the locking arm guides 10a and 10b. The spring force exerted by the guide springs 35a and 35b may cause the locking arms 09a and 09b to be spring-loaded locking arms.

[0074] An expandable snowshoe attachment device for snowboard bindings may include one or more locking rails. The one or more locking rails may be attached to the main body of the device. The one or more locking rails may be attached to a housing of the device. In some embodiments, an expandable snowshoe attachment device includes housing locking rails 11a, 1 lb, 11c, and lid.

[0089] The above description of illustrated implementations of the disclosure, including what is described in the Abstract, is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. While specific implementations of, and examples for, the disclosure are described herein for illustrative purposes, various equivalent modifications are possible within the scope of the disclosure, as those skilled in the relevant art will recognize. [0090] Various operations are described as multiple discrete operations, in turn, in a manner that is helpful in understanding the present disclosure, however, the order of description should not be construed to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation. [0091] The terms “over,” “under,” “between,” “disposed on,” and “on” as used herein refer to a relative position of one material layer or component with respect to other layers or components. For example, one layer disposed on, over, or under another layer may be directly in contact with the other layer or may have one or more intervening layers.

Moreover, one layer disposed between two layers may be directly in contact with the two layers or may have one or more intervening layers. Similarly, unless explicitly stated otherwise, one feature disposed between two features may be in direct contact with the adjacent features or may have one or more intervening layers.

[0092] Various embodiments can have different combinations of the structural features described above. For instance, all optional features of a device or system described herein can also be implemented in a device or system and specifics in the examples can be used anywhere in one or more embodiments.

[0093] While the present disclosure has been described with respect to a limited number of embodiments, those skilled in the art will appreciate numerous modifications and variations therefrom. It is intended that the appended claims cover all such modifications and variations as fall within the true spirit and scope of this present disclosure.

[0094] In the description herein, numerous specific details are set forth, such as examples of specific types of material, specific sizes, specific surfaces, specific structures, specific details, specific configurations, specific types, specific system components, specific operations, etc. in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one skilled in the art that these specific details need not be employed to practice the present disclosure. In other instances, well known components or methods, such as specific and alternative material, sizes, surfaces, structures, details, configurations, types, system components, operations, etc. have not been described in detail in order to avoid unnecessarily obscuring the present disclosure.

[0095] Although some of the embodiments herein are described with reference to specific devices or systems, other embodiments are applicable to other types of structures and surfaces. Similar techniques and teachings of embodiments of the present disclosure can be applied to other types of structures and surfaces that can benefit from advantages described herein. In addition, the description herein provides examples, and the accompanying drawings show various examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the present disclosure rather than to provide an exhaustive list of all possible implementations of embodiments of the present disclosure.

[0096] As used herein, the terms “substantially,” “about,” and/or the like, in some embodiments refer to a range of 2% greater and 2% less, in some embodiments refer to a range of 5% greater and 5% less, in some embodiments refer to a range of 10% greater and 10% less, in some embodiments refer to a range of 15% greater and 15% less, and in some embodiments refer to a range of 20% greater and 20% less,

[0097] Use of the phrase ‘configured to,’ in one embodiment, refers to arranging, putting together, manufacturing, offering to sell, importing and/or designing an apparatus, hardware, logic, or element to perform a designated or determined task. In this example, an apparatus or element thereof that is not operating is still ‘configured to’ perform a designated task if it is designed, coupled, and/or interconnected to perform said designated task.

[0098] Furthermore, use of the phrases ‘to,’ ‘capable of/to, ’ and or ‘operable to,’ in one embodiment, refers to some apparatus, hardware, and/or element designed in such a way to enable use of the apparatus, hardware, and/or element in a specified manner. Note that use of to, capable to, or operable to, in one embodiment, refers to the latent state of an apparatus, hardware, and/or element, where the apparatus, hardware, and/or element is not operating but is designed in such a manner to enable use of an apparatus in a specified manner.

[0099] Reference throughout this specification to “one embodiment,” “an embodiment,” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, the appearances of the phrases “in one embodiment,” “in an embodiment,” and “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[00100] In the foregoing specification, a detailed description has been given with reference to specific exemplary embodiments. It will, however, be evident that various modifications and changes can be made thereto without departing from the broader spirit and scope of the disclosure as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.

Furthermore, the foregoing use of embodiment and other exemplarily language does not necessarily refer to the same embodiment or the same example, but can refer to different and distinct embodiments, as well as potentially the same embodiment.

[00101] The words “example” or “exemplary” are used herein to mean serving as an example, instance or illustration. Any aspect or design described herein as “example’ or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the words “example” or “exemplary” is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X includes A or B” is intended to mean any of the natural inclusive permutations. That is, if X includes A; X includes B; or X includes both A and B, then “X includes A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Moreover, use of the term “an embodiment” or “one embodiment” or “an implementation” or “one implementation” throughout is not intended to mean the same embodiment or implementation unless described as such. Also, the terms "first," "second," "third," "fourth," etc. as used herein are meant as labels to distinguish among different elements and can not necessarily have an ordinal meaning according to their numerical designation.
