Also disclosed is a configurable crampon and a strapless crampon system as well as configurable traction.
2. Description of the Related Art
Approach “randonee” climbing skiing is a popular winter sport that provides backcountry exploration, exercise, and entertainment. Likewise, cross-country skiing, downhill skiing, and snowboarding are enjoyed for many of the same reasons. In a single day, backcountry enthusiasts typically approach ski or snowshoe to their destination and return on skis, snowshoes, or snowboards. Unfortunately for such adventures, enthusiasts must pack extra equipment or heavy equipment for traversing winter terrain. The added weight and hassle of packing up the necessary gear is an obvious disadvantage of these activities of hiking up an incline to then ski or snowboard down an incline.
A solution to the added weight and expense of extra gear, space consuming gear, or heavy gear, is to offer a footwear system in which the boot or shoe of the user is able to mount up to an approach ski system in a fashion wherein the footwear becomes part of the binding. Combining the footwear and the binding eliminates the need for a mounting base or plate for the footwear to mount to. The footwear is then easily removed by quick-release means. When fully released from the approach ski the footwear can be immediately used on a snowboard binding or other winter gear. The ski or (optional) configurable binding plate, in accordance with the present invention may be made of carbon fiber and/or other extremely lightweight materials. Prior approach ski snowboard systems have been extremely heavy to operate and are expensive.
Approach skis are heavy and most do not accept snowboard boots. They do not pack very easily, and they do not offer multi-functions wherein the user may quick release and attach a variety of foot binding set-ups. A split-board is a snowboard design which is able to split into two approach skis able to aid a user in climbing up an incline. When the user desires to snowboard back down the incline they reattach the two approach skis forming a snowboard set-up. The problem with this system includes: weight, expense, does not ski well down hill, and the snowboard does not ride as comfortably as a normal snowboard setup. The approach ski mode is too heavy and limits the range a user can hike because of fatigue.
Three current solutions exist that enable a winter enthusiast to hike up and slide down on a snowboard. The first solution is to use snowshoes up an incline and then snowboard down the incline. Snowshoes are too bulky and do not pack well. They are also to slow in a constant up and down hike in which every small hill you must hike over the snowshoes can only walk down every hill instead of sliding. This method is more tiring and time consuming. Typical snowshoe bindings also offer a flimsy foot binding that prevents the binding and the snowshoe from working effectively together. The second solution is using a split-board which is very heavy, and it is very expensive. The third solution is to use current approach free heel designs that are too heavy and expensive and do not pack well.
What is needed is a device that overcomes weight, expense, and the current function in the art to hike a snowboard enthusiast into the backcountry to eventually ride the snowboard down an incline. What is needed is a light weight device that is relatively inexpensive, easy to use, and is easy to store on a back pack when the snowboard is in use. Additionally, what is needed is a strapless, and extreme light weight foot retention means to hold a hiking boot or snowboard boot to an approach ski without the need of a mounting base plate. A system is needed that eliminates foot retention hardware and straps wherein only the footwear the user uses acts as the binding when coupling means is placed through the footwear.
Additionally, what is needed is a ski that has the capability to have a plurality of foot retaining mounting binding plates that are quick-release and have a variety of designs and functions. One function that includes a detachable ski mounting plate that includes quick-release traction cleats that sit in the heel region and in the toe region forming a crampon with full heel to toe traction. Furthermore, detachable cleats for the mounting plate as well as snowshoes and snowshoe ski systems need a detachable cleat that includes snow and ice sticking repellent in the form of a coupled plastic piece to the crampon.
SUMMARY OF THE INVENTION
The present invention is in response to the current state of the art, and in particular, in response to the problems and needs in the art that have not been fully solved by current available ski, snowboard, snowshoe, their foot binding devices, and needed footwear. Accordingly, the present invention has been developed to provide pivotally equipped able footwear, a light weight climbing approach ski system, and a heel to toe detachable traction for a ski foot binding device or snowshoe binding system in response to needed gear not yet available or developed for backcountry snowboarders, snowshoers, and skiers.

The mounting plate may also have a plurality of pivots as well to have a wide range in which the user can customize the set up in a snowshoe style pivot or an approach “randonee” style pivot dependent on his choice of setting the axle (axis) 2210 and locking it in place with the locking pin 2208.
FIG. 23 is a side perspective view illustrating foot wear or a boot 2204 with a plurality of axis pivot points 2302 allowing the position of pivoting determined in the boot 2204 apparatus. This particular set up offers an alternative to a multi-pivoting mounting plate and a configurable mounting plate in which the boot 2204 with a plurality of pivoting can achieve the same task of coupling a user in a plurality of pivot positions customizing the pivot for approach skiing or snowshoeing etc. In another embodiment the foot ware or boot 2204 may contain only a single pivot in the sole (not shown).
FIG. 24 is a side view diagram illustrating an alternative embodiment of the boot 2400 in accordance with the present invention. As described above with reference to FIGS. 1, 2, 4, and 23, the boot may be configured with one or more multiple pivot points. The pivot points may be configured to receive the axle 52 by either sliding the axle 52 through an opening in the sole of the boot (as in FIGS. 1, 2, and 4) or alternatively the boot may be configure to “step on” the axle as depicted in FIG. 10 and in greater detail in FIGS. 24-27. Likewise, the groove 93 may be closed as depicted in FIGS. 1, 2, and 4, or alternatively the groove 93 may comprise an open portion for receiving the axle 52. As depicted, the boot 2400 has at least one groove 93 in the sole of the boot for receiving the axle 52. The groove 93 may be circular as depicted (for receiving a round axle 52) or, alternatively, the groove 93 may be formed in a shape suitable for the axle being used.
The groove 93, in one embodiment, requires that pressure be applied in order to “snap” onto the axle 52. As such, similar pressure is required to remove the boot. In a further embodiment, the boot may comprise a plurality of grooves 93 positioned in order to enable various different pivot points. For example, if the boot were being used in an approach ski configuration, then a user will snap the axle into a groove 93 under the toe portion 2402 of the boot. Alternatively, if the boot were being used in a snowshoe configuration then a user will snap the axle into a groove 93 under the ball of the user's foot, as indicated by arrow 2404. This beneficially allows for the boot 2400 to pass through the plane of the snowshoe and allow the user to gain traction by digging the toe portion 2402 of the boot into snow or ice.
FIG. 25 is a side view diagram illustrating an alternative embodiment of the boot 2400 in accordance with the present invention. The boot 2400, as depicted, may couple with a ski, snowboard, snowshoe, or other device capable of traversing snow and ice covered terrain. As described above, the ski 31 comprises multiple pivot slots 20 for positioning the axle 52. In one embodiment, the boot 2400 together with multiple grooves 93 allows for positioning of the boot in order to accomplish different pivot points. Alternatively, the pivot slots 20 accomplish similar functionality by enabling a boot with a single groove 93 to be positioned. In another embodiment, a boot with multiple grooves 93 and a ski 31 with multiple pivot slots 20 enables a myriad of boot and pivot configurations.
FIG. 26 is a side view diagram illustrating another embodiment of the boot 2400 in accordance with the present invention. The boot 2400, or other suitable footwear, is depicted “stepping” or “snapping” onto the axle 52. The opening of the groove 93 may be slightly smaller than the axle 52 in order to secure the boot 2400 with the axle 52. Alternatively, the boot 2400 may comprise a removably coupled plate (not shown) that secures the axle 52 in the groove 93.
FIG. 27 is a side view diagram illustrating another embodiment of the boot 2400 in accordance with the present invention. The boot 2400, in one embodiment, may comprise a replaceable groove 2702. The replaceable groove 2702 enables the replacement of a worn groove 93 without the requirement of purchasing a new boot 2400. The replaceable groove 2702 may be attached by any attachment means including, but not limited to, glueing, snapping, or screwing. Additionally, alternative attachment devices may be substituted in place of the replaceable groove 2702 in order to enable the boot to interface with devices including, but not limited to, bicycles, water skis, etc.
FIG. 28 is a perspective view diagram illustrating one embodiment of the approach ski 31 in accordance with the present invention. The approach ski 31, in one embodiment, may comprise a removable portion 2802 coupled with the approach ski 31. The removable portion 2802 is configured to form, together with the approach ski, a substantially continuous skiing surface 2804. The removable portion 2802, when removed, allows the footwear of a user to pass through a plane defined by an upper surface 2806 of the approach ski 31. The removable portion 2802 may be hinged and therefore rotatable, or alternatively the removable portion 2802 may be completely separated from the approach ski 31.
FIG. 29 is a side view diagram illustrating an alternative embodiment of the approach ski 31 in accordance with the present invention. In one embodiment, the removable portion 2802 may be pivoted in a direction indicated by arrow 2902. As depicted, the removable portion pivots downward about a hinge until resting against the skiing surface of the approach ski 31. Similarly, the removable portion 2802, for example, could pivot to the front 2904 or laterally to the sides of the ski 31.
FIG. 30 is a perspective view diagram illustrating a single universal mounting plate 3002 able to be used on a snowshoe 3004, a ski 3006, a snowboard 3008, a hybrid snowshoe ski 3010, and a split-board (not shown). The mounting plate 3002, boot, or configurable mounting plate, may be attached and detached from all of these winter devices that are compatible in a quick-release manner by removing the locking pin 3012 and moving the axle 3014 from the mounting holes 3016. The snowboard has an adapter plate 3018 with adapter plate mounting holes 3020 to allow the universal binding system to be mounted to the snowboard 3008. Straps 3022 to bind the foot couples the user to the universal mounting plate. Quick-release traction 3024 mounts to the universal mounting plate 3002.
FIG. 31 is a perspective view diagram illustrating another embodiment of the boot 2400 in accordance with the present invention. As described above, with reference to FIGS. 24-27, the boot 2400 comprises a groove 93, that in one embodiment, is embedded in the sole 3102 of the boot 2400. The groove 93 is configured to receive and secure the axle 52. The boot 2400 may be configured with multiple grooves 93 (not shown here, see FIG. 24).
FIG. 32 is a side view diagram illustrating one embodiment of the mounting plate 1604 in accordance with the present invention. The mounting plate 1604 comprises straps 3202, 3204 for securing a boot or shoe to the mounting plate 1604. The straps 3202, 3204 may be configured in a similar manner to the strap 1800 of FIGS. 18 and 19. The mounting plate 1604, in one embodiment, comprises a groove 93 for securing the axle 52 as described above with reference to the boot 2400. This beneficially enables footwear that is not configured with a groove 93 to couple with skis, snowshoes, snowboards, approach skis, etc. that are configured with the axle 52.
FIG. 33 is a schematic top view diagram illustrating one embodiment of an approach ski 31 in accordance with the present invention. As described above with reference to FIGS. 28 and 29, the approach ski is configured with the removable portion 2802. The removable portion 2804 is lockable in a closed position as illustrated in FIGS. 28 and 33, and also in the open position illustrated in FIG. 29. The removable portion 2804 is hingedly attached to the approach ski by a hinge 3302. Alternatively, the removable portion 2804 may be completely removed from the approach ski 31 and stored in a backpack, for example.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
