DETAILED DESCRIPTION OF THE INVENTION

[0035] All illustrations of the drawings are to be describing selected embodiments of the present invention and are not intended to limit the scope of the present invention. All references of user or users pertain to either individual or individuals who would utilize embodiments of the present invention.

[0036] Embodiments of the present invention provide systems and methods for traction enhancement, which can be implemented in various backcountry skiing pursuits, for example. Exemplary embodiments disclosed herein are well suited for use in backcountry skiing, providing uphill traction devices that are easy to install and remove, and that do not compromise overall ski performance. In some cases, embodiments can be used in combination with a ski, for example a backcountry ski. In some cases, embodiments can be used in combination with a snowboard, for example a splitboard snowboard. A splitboard is a snowboard which splits into two halves, and the halves can effectively become skis for travelling uphill, downhill, or touring. In some instances, a user will use the halves as skis while climbing uphill, and then reassemble the two halves by coupling them together to form a snowboard, and then ride the snowboard downhill, for example through untracked powder. Because the splitboard halves are effectively used as skis, the term “ski” as used herein encompasses a splitboard half. Embodiments of the present invention encompass ski climbing attachment systems and methods.

[0037] Turning now to the drawings, the upper perspective view of FIG. 1 depicts aspects of a ski climbing attachment system, according to embodiments of the present invention. As shown here, the ski climbing attachment system 100 is coupled with a ski 200. Relatedly, the lower perspective view of FIG. 2 depicts aspects of a ski climbing attachment system, according to embodiments of the present invention. As shown here, the ski climbing attachment system 100 is coupled with a ski 200.

[0038] FIG. 3 provides an upper perspective view of a climbing track assembly 300 of a ski climbing attachment system, according to embodiments of the present invention. A climbing track assembly 300 can be provided as an attachment to the bottom of a ski and that improves traction for hiking or climbing uphill. As shown here, a climbing track assembly 300 can include a base 310 having an upper surface 322 of a central portion 320 and two sidewalls 330, 340. A fastening mechanism 350 is coupled with the base 310. As shown here, fastening mechanism 350 can include a first fastening member 352 and a second fastening member 354. In some cases, fastening members may include buckle or clasp members. Such fastening members can be used to fasten two straps 356, 358 together, so that the straps are held together in a secure and adjustable manner.

[0039] The base 310 of the climbing track assembly 300 can be made of various gauges of sheet metal, of various types and alloys of metal, or of various types and densities of plastic or synthetic materials. The traction device or climbing track assembly 300 can have a cross section of a flattened U shape, with a base 310 having a central section 320 and relatively low upturned sidewalls 330, 340. In some embodiments, the sidewalls 330, 340 are upturned at right angles to the track base central section 320. The sidewalls 330, 340 can provide stiffness to the track base 310, as well as functioning to keep the track base 310 from becoming mis-aligned with the ski when encountering lateral forces, which may occur when hiking on a sidehill. Each sidewall 330, 340 can also incorporate a stiff wire 332, 342 which can be hemmed over or molded into the top of the sidewall. This wire edge can function to increase stiffness of the track base, and the wire edge can also provide a hinge pin 346, 348 for the fastening mechanism 350 (e.g. strap 356 and strap 358 to be attached).

[0040] In some cases, the base 310 is provided with a flat central section 320 and two 90 degree upturned sides 330, 340. In some cases, the base 310 can be made from sheet metal, molded plastic, or synthetic composite materials, In some case, the base 310 can have a length L (as depicted in FIG. 5) having a value within a range from about 14 inches to about 16 inches. In some cases, length L is greater than 16 inches. In some cases, length L is selected to as to provide for easy portability in a day-pack. In some cases, a base 310 have a length L of a greater length can operate to provide increased traction for more aggressive skiers.

[0041] In some embodiments, fastener mechanisms can include, without limitation, a cam style latch or buckle on one side of the track base, and an adjustable strap (e.g. a ladder strap) on the other side. Either or both of the latch/buckle and the adjustable strap can be coupled with the track base via a hinge or hinged arm mechanism. Advantageously, the fastener mechanism can operate to achieve enough leverage when latched to form a very firm attachment between the track base 310 and the ski.

[0042] FIG. 4 provides a lower perspective view of a climbing track assembly 300 of a ski climbing attachment system, according to embodiments of the present invention. In use, a lower surface 324 of the central portion 320 of the base 310 contacts the snow surface. The track base 310 can include any of a variety of materials, such as metal or plastic. In some cases, the lower surface 324 includes or is attached with a friction mechanism 325 such as a texture or surface relief feature that increases friction between the base 310 and the snow. In some cases, the lower surface 324 of the track base which contacts the snow surface has a material 325 adhered thereto that increases friction and therefore improves traction when hiking on or up the slippery slopes. Exemplary friction mechanisms 325 can operate to provide some amount of glide when the ski is pushed forward (e.g. glide between the ski and the snow), and grip when the ski is stepped on or user to propel the user forward or to keep the user stationary (e.g. grip between the ski and the snow). Exemplary friction aids or friction mechanisms 325 can include, without limitation, slant-fiber pile fabric, or sheet plastic material embossed with a one-directional pattern (e.g. in a fish scale pattern). In some cases, these fabrics or plastics can be adhered to the lower surface 324 of the track with adhesives, and/or can be crimpled over with a leading hem 375 (e.g. metal hem) on the leading edge 370 and a trailing hem 385 (e.g. metal hem) on the trailing edge 380 of the track base 310. In this way, it is possible to securely and permanently affix the fabric or plastic to the track base 310. In some cases, the fabric or plastic is temporarily affixed to the track base 310. The lower surface material 325 can be affixed to or crimpled to track base 310 in a variety of ways. In some cases, the crimped material or crimping feature can be either an extension of the track base 310, or it can be a material (e.g. metal or plastic) that is molded into the track base 310.

[0043] Exemplary friction aids or friction mechanisms 325 can operate to contact the snow and provide increased friction between the track base 310 and the snow. In some cases, the friction mechanism 325 can be affixed to the track base 310 via one or more crimps. In some cases, a crimp is an extension of metal track or an extension molded into plastic track. In some cases, a crimp folds over the traction material on the leading and trailing edge of track base and ensures a permanent and durable attachment. In some cases, a crimp or hem also provides for rigidity or stiffness across the base of the track base.

[0044] As shown in FIG. 5, the track base 310 can have a width W. In exemplary embodiments, the width W is selected so as to be compatible with the width of a ski. In some cases, the track width W is configured to be slightly wider than the ski width it is attached to, as long as it does not become a hindrance. In use, the upper surface 322 of the base 310 can be in contact with the ski (e.g. the base of the ski). In some cases, the upper surface 322 has a firm yet compressible material inserted and permanently adhered to the track. This padded insert can help protect the bases and edges of the skis or splitboard while attached to the track during use.

[0045] The climbing track assembly 300 can include a fastening mechanism 350 coupled with the base 310. In some cases, the fastening mechanism 350 includes a cam-style buckle 351 on one side, and an adjustable strap 353 on the other side. The style of fastener can vary and is not limited to the one style listed here. In exemplary embodiments, the fastening mechanism is configured to provide a firm attachment, and to allow the track assembly 300 to be easily installed and removed from a ski. Each side of the fastening mechanism 350 can be held by a hinged connection 388, 389. In some embodiments, a stiff wire inside the hemmed or molded top edge of the track can be exposed at the hinge site, and this exposed wire can operate as a hinge pin for the fastening mechanism straps. The barrel of the hinge can be formed at each end of the straps that connect to the fastener buckle and adjustable strap. The hinges allow for the straps on the fasteners to be spread wide apart for easy attachment and removal of the track assembly 300 to the ski.

[0046] FIG. 6 provides a cross-section view of the base 310, according to some embodiments of the invention. A friction mechanism 325 affixed with the bottom of the base 310 or otherwise incorporated into the bottom of the base 310 can improve traction in the snow. In some cases, the friction mechanism 325 includes a slant-pile fabric, such as synthetic climbing skin material. In some cases, the friction mechanism 325 includes a plastic (e.g. P-tex or polyethylene) base material embossed with fish-scale pattern. As discussed elsewhere herein, in some cases a friction mechanism 325 can be adhered or crimped to the track base 310. In some cases, a climbing track assembly includes a padded mechanism 326, such as an insert, attached with or incorporated into an upper surface of the track base 310. A padded mechanism 326 can be dense yet compressible to protect the base and/or edges of the ski. In some cases, the padded mechanism 326 extends partially or fully up the interior surface or one or both sidewalls 330, 340. The sidewalls 330, 340 can operate to provide stiffness to the track base 310. The sidewalls can also operate to prevent the ski from being mis-aligned in the track base 310. In some cases, a top edge of a sidewall 330 includes a continuous metal wire with a rolled or molded hem 331 around it. The wire and hem can provide the track base 310 with additional stiffness. The wire can also operate as a hinge pin for a strap of a fastener mechanism.

[0047] In some cases, fastener arms or straps attach to the track base 310 where the sidewall rolled hem is notched just enough to expose the wire at the top of the sidewall. In some cases, fastener arm straps can operate to form a barrel of the hinge around the exposed wire of the track base. In some cases, hinges can enable fastener straps to be opened wide for easy attachment between the track base 310 and a ski. In some cases, fasteners or straps are positioned located approximately ⅓ back from leading edge 344 of the track base 310. In some cases, this positioning of the fasteners or straps can operate to ensure that the leading edge 344 of the track base 310 will be held firmly and snug against the upper surface of the ski, thus preventing snow from getting forced between the track base 310 and the base or lower surface of the ski when the user is moving forward through the snow or along the upper surface thereof. What is more, this positioning of the fasteners or straps can help to ensure that the track base 310 will be approximately centered under the skiers toe for maximum traction. In some embodiments, the fastener buckle and strap can be aligned over an included and integral under-binding bracket and then latched firmly to the ski, for example as shown in FIGS. 7-10.

[0048] A climbing track assembly can include an under-binding bracket assembly 700, as shown in FIG. 7. The under-binding bracket assembly 700 can include a bracket 710 and a riser block 720. As shown in FIGS. 7 and 8, the riser block 720 can be positioned between a first tab 712 and a second tab 714 of the bracket 710. In some embodiments, the under-binding bracket assembly 700 includes a lightweight metal plate 711 with two upturned tabs 712, 714 that form a channel 713 therebetween on a forward-facing or front area of the bracket. The channel 713 can be configured to receive the riser block 720. In some embodiments, the riser block 720 includes a firm yet compressible material that can be adhered in the channel 713 between the up-turned tabs 712, 714. As shown here, a bracket 710 can include a catch mechanism 705 configured to receive and/or cooperatively engage with a fastening mechanism. The catch mechanism 705 can include, for example, tabs 712, 714 and/or channel 713. In use, the catch mechanism 705 can operate to maintain the fastening mechanism in fixed positional relationship with the ski, particularly relative to the longitudinal axis or plane of the ski, as the user is hiking while wearing the ski. This cooperative engagement between the catch mechanism 705 and the fastening mechanism enhances the ability of the user to propel their body forward along a snowy surface, with their boot firmly secured with the ski, the ski firmly secured with the climbing track assembly, and the climbing track assembly firmly engaged with the snowy surface.

[0049] As shown in FIG. 9, the under-binding bracket 710 can be mounted to a ski 800 (e.g. under the toe-piece binding of a ski and/or apposed to a top surface 805 of the ski) which can be secured to the base 310 of the climbing track assembly. In some cases, the bracket 710 can be mounted to the ski 800 using the mounting screw template pattern of the existing ski binding for attachment. For example, the bracket 710 can include holes or apertures 770 that match or correspond to the mounting screw template pattern of the ski binding. Advantageously, by using the existing mounting screw template pattern 810, there is no need to drill additional holes into the ski. This will be appreciated greatly by skiers and snowboard riders to not further weaken or allow another path for moisture to invade the integrity of their equipment. In some cases, bracket 710 is mounted beneath an existing ski binding.

[0050] In some cases, the climbing track assembly can include a small shim plate 790 that can be applied under the heel-piece where applicable (e.g. under an existing heel-piece), in order to keep the ski boot in a level plane. In some cases, the shim can be provided as a small lightweight metal plate, and can have a thickness that matches the thickness of the under-binding bracket 710. In some cases, the shim is mounted under the ski heel piece binding to maintain a level foot bed on the ski.

[0051] The fastener buckle 351 and adjustable strap 353 can be engaged together while they are aligned with the channel that is provided between tabs 712, 714. The fastener cam-style buckle 351 can be latched so that it will be captured by or positioned between the metal up-turned tabs 712, 714, and can firmly compress into the riser block 720. Advantageously, this alignment and firm attachment can operate to keep the climbing track 310 from slipping forward or rearward on the ski 800 while in use. Advantageously, the compressible riser block 720 can operate to allow for an easily adjustable, firm, and vibrational dampened attachment of the track 310 to the ski 800, even under jarring conditions.

[0052] In some embodiments, the under-binding bracket 710 can be mounted permanently to the ski (e.g. against an upper surface of the ski) and positioned under the ski toe-piece binding utilizing the existing ski binding screw template. Hence, it is possible that when mounting the bracket 710 to the ski 800 (e.g. coupling the bracket 710 with an upper or top surface 805 of the ski 800), no additional holes need to be drilled into the ski. The bracket 710 can be provided as a lightweight metal plate with upturned tabs 712, 714 forming a channel therebetween which receives fastener straps for alignment therein. The channel between the tabs 712, 714 can also operate to capture or receive at least a portion of the buckle 351 when aligned and latched to help ensure the track base 310 cannot move forward or back relative to the ski 800 while the user is hiking. The channel can be located immediately in front of the ski toe-piece binding. The positioning of the channel (optionally in conjunction with fastener strap location and/or track base length) can help to ensure that the approximate center of track base is centered under the skier's toe. The channel placement can allow a user to achieve friendly access for easy attachment and removal of fasteners. In some cases, the channel has a riser block 720 permanently adhered within it to aid in fastener attachment. In some cases, the riser block 720 can include a dense, compressible foam or equivalent material. In some cases, the riser block can operate to allow the fastener straps to compress when latched to form a more adjustable, firm, yet shock resistant attachment to the ski.

[0053] As shown in FIG. 10, the under-binding bracket 710 can be mounted with the channel formed by the upturned tabs 712, 714 immediately in front of the toe-piece 910 of the ski binding 900, or as near as possible. This placement of the under-binding bracket 710 in conjunction with the location of the fastener straps on the track base 310, and the length of the track base 310 itself, can ensure that when the climbing track assembly 300 is attached to the ski 800, the center or a central portion 311 of the track base 310 will be virtually centered under the skiers toe, and therefore center of the skier's mass while hiking, thus maximizing traction. The fastener straps (e.g. straps 356, 358 depicted in FIG. 3) which are affixed with the track base 310 can be located approximately ⅓ of the way back from the front leading edge 344 of the track base 310. This can help to center the mass as described above, and can also help to ensure a tighter fit on the front leading edge of the track. Advantageously, this can help to prevent snow and ice from being forced between the ski 800 and the leading edge 344 of the track base 310 while moving forward.

[0054] The relative centering of the track base 310 on or under the toe of the user also allows for the track base 310 itself to be of a convenient length and weight to be easily carried in a small day-pack when not in use, or storage. Because the track base 310 is firmly held to the ski 800, and easy to install thereon and remove therefrom, it can be particularly advantageous to more extreme backcountry users to have tracks configured in longer lengths, and/or, with more aggressive traction improving material or a friction mechanism. Such traction improving materials or friction mechanisms can include, without limitation, slant-pile fabrics with longer, stiffer bristles, or other inlayed cleats, or plastic bases with more aggressive fish-scale patterns, with more vertical relief.

[0055] Advantageously, skiers do not need to remove their skis from their shoes or boots in order to attach or remove the climbing track base 310. The convenience of this feature is highly advantageous for the user. In some embodiments, in order to install the climbing track base 310, the skier simply places the track base 310 on the snow next to their ski 800 facing forward. The user can unlatch the fastener buckle 351 and spread the hinges open (e.g. hinges 388, 389 shown in FIG. 5). The user can then step onto the climbing track assembly 300, so that their shoe or boot is on the toe-piece 910, and slide the ski 800 to align the straps 356, 358 with the channel 713 in the binding bracket 710 which is disposed between or otherwise defined by tabs 712, 714. The user can then engage the adjustable strap 353 into the buckle 351 and latch the buckle 351 firmly. The user is then ready to hike. When the user is finished hiking and ready to remove the track base 310, the user can simply follow the above procedure in the reverse order. For example, the user can unlatch the buckle 351, open the hinges 388, 389, step off of the toe-piece 910, remove the base 310 from the ski 800, place the base 310 in their day pack, and proceed to their next destination.

[0056] The frame or base 310 of the device can include 24 gauge steel sheet metal or other types of material, including without limitation aluminum, plastic, reinforced fiberglass, and Kevlar. In some cases, the sides of the base 310 are formed up to add rigidity, and to capture the ski and keep it aligned in a linear orientation when hiking, especially on a side hill.

[0057] The material used can be durable and somewhat resistant against the forces of the buckle 351. In some embodiments, it is the buckle 351 that applies pressure to maintain adequate force against the ski base. This keeps snow from being wedged between the device and the ski when driving forward. The rigidity of the sides can also play a role in this attachment. When the buckle 351 is levered over, the sides of the base 310 can bend in slightly under pressure, and this can help to ensure a firm attachment. Hence, it may be helpful if the material of the base 310 is of adequate rigidity to resist these forces over time.

[0058] In some cases, the placement of the buckle 351 can be approximately ⅓ of the way back from the front of the track base 310. Advantageously, this positioning can help to ensure that the front edge 344 of the track base 310 is firmly held against the ski 800, while still maintaining adequate pressure at the back edge of the track base 310.

[0059] In some embodiments, the placement of the buckle 351 on the device, and the placement of the bracket 710 relative to the toe piece 910 on the ski 800 work together to accomplish multiple objectives. First, the track base 310 can be virtually centered under the toe of the ski boot. This can help to ensure maximum grip, with the user's center of mass positioned directly over the track base 310. Second, it is user-friendly. The skier needs only to reach down in front of the toe piece 910 to buckle or unbuckle the fastening mechanism and release the track base 310 from the ski or attach it therewith.

[0060] The buckle 351 can be provided in any of a variety of styles. For example, the buckle 351 can be a lever style buckle or a ratchet style buckle. Other buckle styles are encompassed by embodiments of the present invention. In exemplary embodiments, it allows firm enough pressure to hold the track base adequately against the ski.

[0061] In some cases, the bracket 710 that the buckle 351 is placed in while fastened can also provide important benefits. In some cases, the bracket 710 can help to hold the track base 310 from sliding forward or back relative to the ski 800 while in use. The act of hiking in skis applies pressures to slide the track base 310 forward or backwards relative to the ski 800, and the bracket 710 can help to hold the track base 310 firmly against the ski 800, thereby allowing the skier to move efficiently across the ground or snow. In some cases, the bracket 710 can be incorporated into a plate under the binding toe piece 910, allowing for the climbing track assembly 300 to be used without additional holes being drilled into the ski. Climbing track assemblies disclosed herein are well suited for use in cold temperatures, as compared to other existing solutions that rely on adhesives which may not perform well in cold or wet conditions.

[0062] When hiking uphill, the forward step is often important, and it applies pressure to attempt to slide the device forward on the ski. The bracket 710 and track base 310 with climbing skin material or fish scale ski material will perform this step effectively. This could be made more effective with more aggressive traction material applied to the track base 310. Forward traction is important in hiking uphill, however the movement of the ski forward with the least resistance in order to make another step is also important. This motion is known as the glide. Glide is an important part of the hiking motion. Too much resistance inhibits glide and causes extra effort and wastes energy. The climbing skin material or fish scale base material are utilized also for their glide properties. When hiking on level or downhill slopes, the pressures are to force the track base 310 in a backward direction on the ski. The bracket/buckle on the track base 310 hold these forces in check as well. The material or friction mechanism can include a one-way nap that allows forward motion of the ski and resists backward motion of the ski.

[0063] FIG. 11 depicts additional aspects of a climbing track assembly, according to some embodiments of the present invention. As shown here, a first wire 1110 can be disposed within a first hem 1120 and a second wire 1130 can be disposed within a second hem 1140. The hems may include cut-outs (e.g. cut-out 1102) where portions of the wire are exposed, and the exposed wire portions can be coupled with straps 1150, 1160 at hinged connections 1170, 1180, respectively. Wires may extend along a full length of a track base 1190, or along a portion thereof.

[0064] In some embodiments, devices may incorporate web strap material and/or web cam buckles. Other features may provide equal or greater effectiveness in actual hiking/skiing situations.

[0065] In some cases, a device may include one or more web straps instead of hinges, and an adjustable web strap “over center” buckle with the “catch” riveted to the web strap. In some cases, devices may include a web strap using a cam type strap buckle. It is desirable to provide an attachment mechanism that holds the strap tight enough and that does not slip when hiking. It is also desirable to provide a mechanism such as an adjustable over center buckle that confers sufficient leverage. Exemplary embodiments include a ladder strap/buckle. In some cases, devices include a skin material or fish scale base material attachment at the bottom of the device. In some cases, such skin material can be attached with the track base and the metal hemmed over it front, back, and along the sides. In some cases, the material can be secured via crimping. A lower hinge placement (e.g. pin and hinge) can allow the strap to be close to the ski. A notch can help promote such placement.

[0066] In some cases, devices can be manufactured by hemming them in the front and back. In some cases, devices are not hemmed on the sides. In exemplary devices, skin material remains adhered along the entire base of the device. The side hem may provide a cleaner appearance as well. In some embodiments, hinges are riveted to the sides.

[0067] FIG. 11A depicts additional aspects of a climbing track assembly 400, according to some embodiments of the present invention. As shown here, a fastening mechanism 450 can be in pivoting engagement with a base 410. For example, a strap of a fastening mechanism can be in pivoting engagement with an upper hem of the base 410. As shown here, fastening mechanism 450 includes a strap 1450, and base 410 includes a first upper hem 1420 and a second upper hem 1440. In some embodiments, a base 410 may include a sidewalls 430, 440. A sidewall of a base may include a slit which helps to provide engagement between a fastening mechanism and the base. As shown here, sidewall 430 includes slit 432 and sidewall 440 includes slit 442. Sidewall slit 432 receives a portion of fastening mechanism 450 to provide a pivoting engagement therewith. For example, sidewall slit 432 can receive a portion of a strap, or a portion of a cylindrical barrel that is coupled with the strap. As shown here, fastening mechanism 450 includes a barrel 455. In some cases, either or both of the upper hems may at least partially house or contain one or more wires. In some cases, one or more wires (e.g. hemmed wires) may extend along a full length of a track base, or along a portion thereof. In some cases, a sidewall slit is positioned directly beneath a hem or a hemmed wire. A sidewall slit can allow a component of a fastening mechanism (e.g. strap or barrel) to wrap around an intact hemmed top of the base, thereby providing continuity of a hem (e.g. without a notch, such as the notch depicted in FIG. 11). In some cases, by not exposing a wire (e.g. by the presence of a notch), the base can be stronger and more resistant to deflection at the fastening mechanism or strap attachment point.

[0068] In some embodiments, a base may include a central portion that is in crimped engagement with one or more sidewalls. As shown in FIG. 11A, base 410 may include a central portion 420 that is in crimped engagement with sidewalls 430, 440. A sidewall can include a lower hem that engages or crimps the central portion. As shown here, sidewall 430 includes a lower hem 1470 that engages or crimps central portion 420, and sidewall 440 includes a lower hem 1490 that engages or crimps central portion 420. In some cases, a central portion may include a lower side having a fish scale surface. Central portion 420 can be provided in any of a variety of widths. (e.g. to match a width of a ski). In some cases, the central portion can be manufactured from plastic, the sidewalls can be manufactured from metal, and the metal sidewalls can be crimped firmly to the plastic central portion. In some embodiments, such construction can help to provide the strength needed to overcome linear deflection when buckled tightly to the ski.

[0069] According to some embodiments, a climbing track assembly can include a bracket assembly 1700, as shown in FIG. 12. The bracket assembly 1700 can include a bracket 1710 and a riser block 1720. The riser block 1720 can be positioned between a first tab 1712 and a second tab 1714 of the bracket 1710. In some embodiments, the bracket assembly 1700 includes a lightweight metal plate 1711 with two upturned tabs 1712, 1714 that form a channel 1713 therebetween on the bracket. The bracket 1710 can include or be manufactured from any of a variety of materials, including without limitation plastic, metal, and the like. In some cases, the upturned tabs 1712, 1714 can operate to provide a barrier to keep the climbing straps and buckle from sliding relative to the ski. In some cases, and as further discussed elsewhere herein (e.g. with reference to FIG. 13), the shape of the riser block itself can operate to provide a barrier to keep the climbing straps and buckle from sliding relative to the ski.

[0070] In some cases, the plate 1711 may include one or more apertures (e.g. 1711a, 1711b) through which screws or other fastening mechanisms may be placed or engaged so as to secure the plate 1711 with a ski. In some cases, one or more of the tabs and/or plate may include a metal or plastic material. In some cases, a riser block may be adhered to or otherwise coupled with the plate 1711. In some cases, a riser block may be adhered to or otherwise coupled with a ski (e.g. to the upper surface of a ski). In some cases, a riser block can be adhered to or otherwise coupled with a plate, where the riser block is positioned at least partially between the upturned tabs 1712, 1714.

[0071] The channel 1713 can be configured to receive the riser block 1720. In some embodiments, the riser block 1720 includes a firm yet compressible material that can be adhered in the channel 1713 between the up-turned tabs 1712, 1714. As shown here, a bracket 1710 can include a catch mechanism 1705 configured to receive and/or cooperatively engage with a fastening mechanism. The catch mechanism 1705 can include, for example, tabs 1712, 1714 and/or channel 1713. In use, the catch mechanism 1705 can operate to maintain the fastening mechanism in fixed positional relationship with the ski, particularly relative to the longitudinal axis or plane of the ski, as the user is hiking while wearing the ski. This cooperative engagement between the catch mechanism 1705 and the fastening mechanism enhances the ability of the user to propel their body forward along a snowy surface, with their boot firmly secured with the ski, the ski firmly secured with the climbing track assembly, and the climbing track assembly firmly engaged with the snowy surface.

[0072] In use, the bracket assembly 1700 may be used in combination with one or more aspects of a climbing track assembly disclosed herein (e.g. aspects of climbing track assemblies depicted in FIGS. 3, 4, 5, 9, 10, and 11). Such a bracket assembly 1700 does not include a posterior portion 717 such as that which is shown in FIG. 7. Hence, bracket assembly 1700 can be used with straps and buckle of a climbing track assembly, allowing one or more straps and/or a buckle to engage with the riser block so as to provide a firm non-slip attachment with the ski without requiring a full under-binding bracket. In some embodiments, use of bracket assembly 1700 can be used in combination with a ski binding. For example, with reference to FIG. 10, a bracket assembly can be used in combination with ski binding 900, without necessitating removal and/or (re)attachment of a toe-piece 910 with an under-binding bracket or portion thereof, such as a posterior portion 717 of a bracket 710.

[0073] In some cases, a riser block 1720 and/or bracket 1710 can be permanently attached with a ski (e.g. using a permanent adhesive or other fastening means, such as screws, pins, nails, and the like). In some cases, a riser block 1710 and/or bracket 1710 can be temporarily attached with a ski (e.g. using a semi-permanent adhesive), for example if a user wishes to try out or demo a riser block and/or bracket with a ski prior to permanently affixing the riser block and/or bracket to the ski. In some cases, such temporary attachment can be beneficial for a user who may not have the requisite tools and/or skills needed to permanently attach a riser block and/or bracket with a ski. In some cases, such temporary attachment can be beneficial to a user who may not wish to expend the time and/or cost to have a ski shop technician provide such services.

[0074] In some cases, a riser block 1720 and/or bracket 1710 can be attached with a ski at a location that is anterior or in front of a ski binding toe-piece, such as toe-piece 901 depicted in FIG. 10. Likewise, the riser block 1720 can be engaged by one or more aspects (e.g. buckle and/or strap) of a fastening mechanism, such as fastening mechanism 350 depicted in FIGS. 3, 5, 9, and 10.

[0075] In some cases, a riser block can be used without an accompanying bracket. For example, as shown in FIG. 13, riser block 1720 can be coupled permanently (e.g. using a permanent adhesive or other fastening means, such as screws, pins, nails, and the like) or temporarily (e.g. using a semi-permanent adhesive), with an upper surface 805 of a ski. As shown here, riser block 1720 can be engaged by one or more aspects of a fastening mechanism 1350, such as strap 1356, strap 1358, and/or buckle 1351. In some cases, a riser block 1720 may be provided with a peel and stick adhesive assembly on the bottom surface thereof. In operation, a user may peel off a protective film of the assembly and then place the exposed adhesive material of the assembly against the ski.

[0076] Hence, as shown in FIG. 13, a ski climbing attachment system may include a riser block, and not an under-binding bracket assembly having a bracket and a catch mechanism with upturned tabs. However, in some cases, a ski climbing attachment system can include a bracket assembly having a riser block, optionally in combination with a bracket with upturned tabs. In some cases, a ski climbing attachment system can include a riser block bae of a dense foam or pad. In some cases, a ski climbing attachment system can include a piece of dense foam or felt riser pad which uses an adhesive to glue it to the top of the ski (with or without screws or other fastening means). The buckle and straps of the climbing track hinge pieces can engage the riser pad very firmly when the buckle is latched over the ski. The buckle and strap can crush down into the dense riser block and this can prevent or inhibit the climbing track from sliding forward or backward on the ski during use. The riser pad can be shaped in such a way to capture the strap and buckle efficiently, for example by using an hourglass or similar shape, such as a “H” shape. A strong and durable adhesive can be used to keep the riser block attached to the ski, and such a configuration can be constructed without using a metal under-binding plate (UBP), and in some cases such a configuration may be more user-friendly. For example, there would be no need to remove the ski binding toe piece, no need to drill holes in the UBP to match the existing binding screws, and no need to then re-attach the toe piece. Such features can operate effectively to eliminate the need for a ski technician to be involved, thereby saving money, time, and potential complications for the user.

[0077] In some cases, by actuating or engaging the strap and buckle clasped firmly, it is possible to compress the riser block so that the climbing track is held fast, with little or no sliding. In some case, a riser block can include dense foam, felt, rubber, urethane, and the like, or other materials as discussed elsewhere herein. A riser block can have any of a variety of shapes, including without limitation rectangular, arch shaped, hourglass, having ridges, and the like. In some cases, a riser block can be provided on a metal frame which does not extend under a binding. In some cases, a riser block remains firmly adhered to the ski when the climbing track assembly is removed from the ski.

[0078] A riser block can include or be manufactured from one or more firm, dense, compressible materials. For example, suitable riser block materials may include rubber, dense foam rubber, plastic, urethane, felt, fabric, and the like.

[0079] With continuing reference to FIG. 13, in some cases, the shape of the riser block 1720 can operate to provide a barrier to keep the climbing straps and buckle (or other aspects of a fastening mechanism) from sliding relative to the ski. As shown in FIG. 14, a riser block 1820 may include ridges (e.g. anterior ridge 1822 and posterior ridge 1824) between which aspects of a fastening mechanism may be positioned. As shown in FIG. 15, a riser block 1920 can include side-cuts (e.g. left side-cut 1922 and right side-cut 1924) within which aspects of a fastening mechanism may be positioned. In this sense, riser block 1920 can be considered to have an hourglass shape. According to these embodiments, the shape of the riser block can provide a recess or other indentation or channel into which the climbing track straps and buckle (or other aspects of a fastening mechanism) can lay into or engage, when the riser block is in use.

[0080] FIGS. 16A-C provide a multiview orthographic illustration of the riser block 1820 of FIG. 14. As shown in the front view (FIG. 16A), side view (FIG. 16B), and top view (FIG. 16C), riser block 1820 includes an anterior ridge 1822, a posterior ridge 1824, and a channel 1823 therebetween.

[0081] In some embodiments, a riser block may not include a recess or side-cut. For example, as shown in FIGS. 17 and 18, riser blocks 2020, 2120, respectively, do not include a recess or side-cut. In use, the compressive action or forces of one or more aspects of a fastening mechanism can operate to press against the riser block, thereby deforming a central area 2023, 2123 of the block, resulting in uncompressed or less compressed anterior areas 2022, 2122 and posterior areas 2024, 2124 which then function to provide a barrier to keep the climbing straps and buckle (or other aspects of a fastening mechanism) from sliding relative to the ski. This can provide a mechanism by which the riser block material alone can provide or contribute to resistance which keeps the climbing track from sliding relative to the ski when in use. Hence, a firm compressible material of the riser block can deform when the straps and buckle (or other aspects of a fastening mechanism) are engaged or deployed, thereby implicitly forming a barrier in the riser block itself to keep the straps and buckle (or other aspects of a fastening mechanism) from sliding forward or backward. In some cases, the riser block can be made with a longer length, so as to increase the width of one or more of the uncompressed ridges (anterior and/or posterior) which are positioned on either side of the straps and buckle (or other aspects of a fastening mechanism), thereby increasing the width of the resulting barrier which prevents or inhibits sliding.

[0082] FIG. 19 provides a side view of a riser block 2220 according to embodiments of the present invention. As shown here, riser block 2220 can include or be coupled with an adhesive mechanism 2227, such as an adhesive material, or an adhesive assembly such as a peel and stick adhesive assembly.
