Patent Application
20190046861
This application claims priority from Canadian Patent Application serial number CA2,919,402 filed on Feb. 1, 2016, entitled Foldable Snow Bike, which is expressly incorporated by reference herein to the fullest extent permitted by law.
The present invention relates to apparatus to slide a person over terrain, such as terrain covered by snow, ice or sand for example, including for athletic, recreational, or transportation uses, for example transiting down a mountain.
Apparatus for sliding a person over terrain are known, for example:
Conventionally, such vehicles tend to convey a person as a passenger, more passively than the athletic equipment, but might offer instead greater protection and adaptability to a wider variety of terrains and conditions. Conventionally, the athletic equipment tends to support its user's own movement, enhancing his abilities, but generally leaving him less protected and therefore perhaps inclined to challenge only safer or more groomed terrains.
Accordingly, what is needed is an intermediate apparatus that offers some of the benefits of both athletic equipment and vehicles—a snow bike—that can be portable and thrilling like athletic equipment, can be adapted for, and offer some degree of protection against, a variety of terrains, and can be tuned for a variety of user characteristics and preferences.
The present invention is directed to this need.
According to one aspect of the present invention, there is provided an apparatus for attachment to a slidable runner at forward and aft attachment points, the apparatus having: an elongated support with a handlebar end and an opposite footrest end; a handlebar assembly connected to the handlebar end of the support; a footrest assembly proximate to the footrest end of the support; a forward bar, pivotally connected to the footrest end of the support and pivotally attachable to the forward attachment point of the runner; an aft bar, pivotally connected to the forward bar and pivotally attachable to the aft attachment point of the runner; and a suspension assembly coupling at least one of the forward bar and aft bar to the support. The handlebar assembly may be pivotally connected to the handlebar end of the support.
The location at which the aft bar is pivotally connected to the forward bar may be user-selectable and may include a limiting subassembly adapted to limit pivoting at the connection between the aft bar and the forward bar. In this regard, the limiting subassembly may include a locking pin.
The suspension assembly may include a first strut assembly connected between the aft bar and the support and a second strut assembly connected between the aft bar and the forward bar. At least one of: the location at which the first strut assembly is connected to at least one of: the aft bar, and the support, and the location at which the second strut assembly is connected to at least one of the aft bar, and the forward bar may be user-selectable.
To provide for transforming the apparatus between a folded configuration, for storage or transport, and an unfolded configuration for use, at least one of the connection between the handlebar assembly and the support, the connection between the forward bar and the support, the connection between the aft bar and the forward bar, the connection between the first strut assembly and the aft bar, the connection between the first strut assembly and the support, the connection between the second strut assembly and the aft bar, and the connection between the second strut assembly and the forward bar may be adapted to be at least one of connected, disconnected and pivoted by a user.
The apparatus may include the runner.
Further aspects and advantages of the present invention will become apparent upon considering the following drawings, description, and claims.
The invention will be more fully illustrated by the following detailed description of non-limiting specific embodiments in conjunction with the accompanying drawing figures. In the figures, similar elements and/or features may have the same reference label. Further, various elements of the same type but in different embodiments may be distinguished by different most-significant digits.
The structure of the invention will now be illustrated by explanation of specific, non-limiting, exemplary embodiments shown in the drawing figures and described in greater detail herein.

With reference now to
The apparatus 100, 200, 300 may be configured in a folded configuration (e.g.
Thus, in the process of unfolding the apparatus 100, 200, 300 into an unfolded configuration, a user would pivot the handlebar assembly 108, 208, 308 away from the support 102, 202, 302, the forward bar 116, 216, 316 away from the support 102, 202, 302 and the aft bar 118, 218, 318 away from the forward bar 116, 216, 316. The user would also fully unfold the handlebar assembly 108, 208, 308 and the footrest assembly 110, 210, 310 at their lockable pivots 112, 212, 312.
To tune the apparatus 100, 200, 300 for the particular characteristics of the user, the terrain (or the weather or more broadly the environment) or the runner 1000, 2000, 3000 or the preferences of the user, the pivot points of the apparatus 100, 200, 300 might be adjusted, for example as between the forward bar 116, 216, 316 and the aft bar 118, 218, 318 or between the first strut assembly 126, 226, 326 and either the support 102, 202, 302 or the aft bar 118, 218 or the forward bar 316, or between the second strut assembly 128 and either the forward bar 116 or the aft bar 118. Some pivot points might be limited, for example via the limiting subassembly 122, 222 for example with a locking pin 124, 224. During this unfolding and tuning, the user would also attach the apparatus 100, 200, 300 to the runner 1000, 2000, 3000, by attaching the forward bar 116, 216, 316 to the forward attachment point 1002, 2002, 3002 via the forward footing 117, 217, 317 and the aft bar 118, 218, 318 to the aft attachment point 1004, 2004, 3004 via the aft footing 119, 219, 319.
When finished using the apparatus 100, 200, 300, whether temporarily (for example for a meal break or for transport back up a mountain), or for a longer period of time (for example at the end of a day or a season), the user might reverse some or all of these steps to fold the apparatus 100, 200, 300 into a folded configuration (such as shown in
Thus, it will be seen from the foregoing embodiments and examples that there has been described an apparatus for attachment to a slidable runner, adjustable between a folded configuration for transport or storage and an unfolded configuration for use, and tunable to match various terrain characteristics and user characteristics and preferences.
While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims. In particular, all quantities described have been determined empirically and those skilled in the art might well expect a wide range of values surrounding those described to provide similarly beneficial results.
It will be understood by those skilled in the art that various changes, modifications and substitutions can be made to the foregoing embodiments without departing from the principle and scope of the invention, as expressed in the claims made herein.
While the invention has been described as having particular application for personal use, those skilled in the art will recognize it has wider application.
