BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to winter sports equipment and more particularly relates to a winter footwear pivot system allowing transition from one binding apparatus to another providing different modes of winter foot travel with a footwear pivot system. 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 apparatus, in one embodiment includes a device having a removable axle, the device configured to traverse terrain, a groove connected with a boot for receiving the axle, and wherein the groove is configured to enable the boot to pivot about the axle and securely couple the boot with the axle. In a further embodiment, the groove is formed in the boot, or alternatively, the groove is formed in a mounting plate removably attachable with a boot. In one embodiment, the groove is configured to receive an axle slidably inserted into the groove, or the groove is configured to snap onto the axle.
In one embodiment, the device is selected from a group comprising a ski, snowshoe, snowboard, hybrid snowshoe ski, or an approach ski. The apparatus may also include a plurality of grooves connected with a boot, and/or a plurality of pivot slots for receiving the axle and configured to support the boot.

It must be noted that the retracting traction system can also be used on other type device bindings and mounting plates as well and would be obvious to one skilled in the art to utilize retracting traction cleats on other winter foot bindings and mounting plate devices not named in this disclosure.
FIG. 22 is a perspective view diagram illustrating a configurable ski 2200 with a plurality of axis pivots 2202 in which to pivot the mounting plate or boot 2204 (See FIG. 23). The axle 2206 can be removed by releasing the locking pin 2208 and allowing the axle to be placed in any of the plurality of axis pivots 2202 on the configurable ski 2200. 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.
