Definitions

  • This invention relates to devices used for traversing ice and snow, and more particularly relates to collapsible skis that can be easily stowed and carried between uses. DESCRIPTION OF THE RELATED ART
  • the collapsible or foldable skis of the past predominantly have two sections that are joined near a center of the ski by hinges and/or locking mechanisms.
  • the locking mechanisms are for holding the collapsible or folding skis in a deployed configuration, but typically have weak points and are prone to breakage under regular conditions of use for skis.
  • Other devices used for traversing ice or snow include snow shoes. However, snow shoe devices are limited in their sliding and maneuvering capability.
  • skis Since it is cumbersome to pack full-length skis and because of the large space requirement, some folding skis have been developed. However, the skis typically fold approximately in half such that they are at least 50% as long as full-length skis. These skis typically have hardshell boot bindings, which take up additional space. As such, these skis are too long and bulky to fit into a snowmobile or backpack pocket. Furthermore, these skis are structurally very complex and expensive. Snowmobile enthusiasts sometimes experience engine trouble or machine breakage. The snowmobile may become stuck with no way to free the snowmobile. These situations can be life-threatening when may require a user to hike for help because they have not brought appropriate foot traveling devices that will enable the user to hike for help. It is difficult to walk or otherwise maneuver in deep fresh snow without skis or snow shoes. Moreover, even if a user desired to pack snowshoes or skis, those devices, as they are known in the prior art, are not capable of being stowed and fit into compartments of snowmobiles or backpacks.
  • an apparatus, system, and method that have the benefits of skis and the benefits of snow shoes.
  • an apparatus, system, and method would include foldability such that the apparatus may be a ski or snow shoe that can be folded into a compact volume that is less than half the length of the skis or snow shoes.
  • the apparatus when deployed, should have excellent maneuverability in ice, snow, and powder conditions.
  • the present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available folding skis and snow shoes. Accordingly, the present invention has been developed to provide an apparatus, system, and method for stowing skis or snow shoes in a compact volume that will easily fit in a back pack or snow mobile compartment, and which overcome many or all of the above-discussed shortcomings in the art. Indeed, the apparatuses of the present invention enable a user to more easily climb, slide, turn, and otherwise maneuver when traversing ice, snow, or power.
  • an apparatus for traversing ice and snow in accordance with embodiments of the present invention includes a collapsible body having a bottom surface for traversing ice and snow covered terrain and a top surface for supporting a user on the ice or snow.
  • the apparatus also includes at least two hinge areas such that the body is divided into at least three sections by the two hinge areas.
  • the apparatus also has at least two separate locking mechanisms on the body proximate to the two hinge areas.
  • the locking mechanisms are configured to hold the at least two hinge areas in a deployed mode with the sections aligned with each other when locked.
  • the locking mechanisms are also configured to release the two hinge areas in a collapsed mode, thus enabling the sections to be stowed in a mutually overlying configuration when unlocked.
  • the apparatus may further include an adjustable attachment mechanism coupled to the top surface for adjustably attaching footwear to the top surface of the apparatus.
  • the adjustable attachment mechanism has a mounting platform configured to secure footwear to the apparatus.
  • the platform is releaseably coupled to the top surface of the apparatus.
  • the platform may have at least one strap attached thereto for engaging hard or soft shelled footwear
  • a system for selectively deploying and stowing a device for traversing snow or ice in accordance with embodiments of the invention includes a body having a plurality of sections movable between a deployed mode forming a ski or snow shoe and a stowed mode in which the sections are collapsed into overlying relation relative to each other.

  • the binding position elements are configured for pivotally coupling footwear at a plurality of positions generally corresponding to the binding position elements along the body.
  • the plurality of binding position elements are positioned on the front half of the body in the deployed mode.
  • a method of using a collapsible device for traversing snow or ice may include unfolding at least three sections of a ski or snow shoe and locking the at least three sections in an aligned, generally rigid, deployed configuration.
  • the method may also include coupling footwear to the device at a position in a front half of the device. Coupling the footwear may include adjustably coupling a binding platform to one of a plurality of binding mounting elements on the front half of the device.

  • Lock mechanisms may also coupled to tether hole 10 to hold the hinge locks 4 in a locked hinge or deployed configuration.
  • the hinge locks 4 may include bolts or braces 6 guided in slider slots or channels formed at least in part by keepers 12 located on a top surface of the skis 1.

Abstract

Un ski pliant (1, 90) fait partie d'un système pour traverser un terrain couvert de neige et de glace. Le ski (1, 90) est conçu pour passer d'un état déplié et raccourci en longueur à un état rabattu. Le ski (1, 90) ainsi rabattu peut alors se loger dans de petits espaces, tels que dans des compartiments de motoneige ou des poches de sac à dos. Le ski est muni d'une pluralité de charnières (2, 3, 92, 93), sections (14, 22, 24, 102, 105, 108), et mécanismes de verrouillage (4) conçus pour faire passer les sections de l'état déplié à l'état rabattu et vice versa. Le ski (1, 90) peut également comprendre un mécanisme pour raccorder par pivotement une chaussure au ski, qu'il s'agisse d'une botte à coque rigide ou d'une botte à coque souple pour la randonnée, le ski, la motoneige et/ou le surf des neiges. Le mécanisme de raccordement de la chaussure peut comprendre une plate-forme de fixation réglable (26, 36) en position et/ou longueur.
