This disclosure relates to devices for aiding persons in motion under their own power, and more particularly, to handheld poles for supporting and propelling said persons.
The use of handheld poles by persons propelling themselves in motion is known. For example, skiers commonly use two poles, one held by each hand, and hikers frequently use one or two walking or trekking poles. Additionally, persons with impaired balance use support poles to help them walk or balance as they walk. Typically, these support poles include hiking poles, crutches, canes, or other such similar devices.
In one aspect a handheld device is disclosed that includes a pole comprising a curved or a bowed shape. The pole is structured and configured to aid persons in motion under their own power. The disclosed pole can comprise two or more sections that have substantially different shapes. In some embodiments, the disclosed pole can include two or more sections. At least two of the sections are not congruent. In some embodiments at least two of the sections comprise a curvature but are not substantially coplanar.
In another aspect, a handheld device is disclosed that can include a pole comprising a curved or a bowed shape. The disclosed pole can be structured and configured to aid persons in motion under their own power. The pole can include an inverted middle section or a lesser-curved middle section.
In another aspect, a handheld device is disclosed that includes a pole having a curved or a bowed shape. The disclosed pole can be structured and configured to aid persons in motion under their own power. The pole can include a top portion and a bottom portion and the pole can include either a paddle or a ski shoe attached to its bottom portion, or a cross-handle attached to its top portion or a combination thereof.
In this application,
the term “cross handle” refers to a projection attached to a disclosed pole, usually at the top portion, that is not aligned with the top portion and forms a stop or limit for a hand grip so that the hand does not slide down the top portion.
the term “hook foot” refers to an element that has an adjustable hook mounted onto the lower portion of a disclosed pole;
the terms “section” and “portion” are used interchangeably;
the term “ski shoe” refers to a foot portion that includes a ski element; and
the terms “user” and “person” are used interchangeably;
This disclosure relates to devices for aiding persons in motion under their own power, and more particularly, to handheld poles for supporting and propelling said persons. Various embodiments are described in detail with reference to the drawings, in which like reference numerals may be used to represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the systems and methods disclosed herein. Examples of construction, dimensions, and materials may be illustrated for the various elements, and those skilled in the art will recognize that many of the examples provided have suitable alternatives that may be utilized. Any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the systems and methods. It is understood that various omissions and substitutions of equivalents are contemplated as circumstances may suggest or render expedient, but these are intended to cover applications or embodiments without departing from the spirit or scope of the disclosure. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting.
The present disclosure describes improved designs for poles that can be used, without limitation, by walkers, hikers, runners, trail-runners, and skiers.
Middle portion 104 can have many configurations, some of which are additionally described below in reference to
The middle portion 104 can be curved in the opposite direction of arc, as compared to the top and bottom portions. The top section can be flat, indented, have a ridge, or round in order to accommodate a human hand's grip or addition of an accessory hand grip, wrap, or collar. For each portion or section, the degree of curvature of that section can vary depending on materials used, amount of flex desired for particular purpose, or overall length customized to user height or user preference. Any section can be made of a different material than any other section. Such a material can include wood, laminate, carbon fiber, fiberglass, or metal.
The spring action of the disclosed poles can provide benefits for users. As compared with more rigid poles, the disclosed poles can still aid a user's stability while impacting the body more gently. The disclosed poles can flex to different distances between handle and foot permitting a user's body, particularly their arms and upper body, to follow a more varied range-of-motion while walking/running/skiing/etc., as compared with the more restricted pattern(s) of motion that a user's body might be constrained to with conventional rigid poles. Energy stored in the disclosed pole when flexing the disclosed pole as a spring can be returned to the user, to the benefit of the user's motion, when the disclosed pole is un-flexed later in the user's motion. This can allow for a gentler way for users to use their arms to augment their forward motion.
In a second loaded or compressed state, the disclosed pole (shown in one embodiment in
The disclosed pole can have a variety of shapes within the general description of a curved bow. Any curve in the disclosed bowed pole may be radially consistent or inconsistent with the others describing, in some cases, the arc of a perfect circle while in other cases, an arc of tightening or loosening spiral sections of the curve may also deviate from the planar. Two illustrative examples are shown in
Alternatively, as shown in
Multiple sizes of poles can be provided such that users can select poles matching their heights. In some embodiments, the disclosed poles may be modular. For example, the disclosed poles can be structured and configured to be taken apart into two or more sections enabling the disclosed poles to change their height. Such modular poles may allow a user to switch out sections of the disclosed pole and replace them with other sections. The modular poles may also allow a user to more easily store or carry the disclosed poles. In some embodiments, any section of any of the one of the disclosed poles, or the disclosed pole as a whole, may be telescopic to allow for height or grip adjustment. Poles can fit together manually by inserting, screwing, locking, fitting, or affixing by use of a collar, wrap, tie, or another component.
Poles of the present disclosure can be manufactured of any suitable materials, in any suitable configuration, and by any appropriate methods. They can be manufactured of, without limitation, wood (in some cases, in a laminated construction), carbon fiber, fiberglass, graphite, and/or polymers. Furthermore, if there is more than one section, the sections can be comprised of the same or different materials.
In some cases, poles can be manufactured with round cross-sections. In some other cases, poles can be manufactured with rectangular cross-sections, or another non-round cross-section, which can contribute to different flexure properties (e.g., spring constants) in different planes. For example, a pole can be manufactured to be more flexible (lower spring constant) in the plane of curvature of the bowing of the disclosed pole, while it can be substantially stiffer (higher spring constant) perpendicular to that plane.
The top section of a modular pole (for example, near a top end of the bowed pole) can flatten, indent, ridge, or round to accommodate a human hand's grip, or addition of an accessory hand grip, wrap, or collar may be added to the top section. In some cases, the disclosed pole can include a handle structured and configured for a user to grip. In other cases, the disclosed pole can be grabbed, gripped, or grasped substantially anywhere along its upper length. The handle can have any appropriate shape. In some cases, the handle can be a round portion of the disclosed pole and can be approximately two inches in diameter. In some cases, the handle can have a shape that is specifically molded to improve grip-ability by a hand. In some cases, the disclosed pole can include an attached wrist strap, which can be selectively detachable or can be permanently attached to the disclosed pole.
The disclosed pole can include, at a bottom section a foot portion that is structured and configured for contact with the ground. The bottom section (foot portion) can be structured and configured to provide stability with ground contact. In various cases, the foot portion can be (without limitation) tapered, spiked, clubbed, and/or rubberized, or any combination of these configurations.
Any section (for example, top, middle, or bottom) of the disclosed pole may come to an end that is blunt, sharp, bulbous, flattened, or hooked by varying degrees. The bottom end of the disclosed pole may additionally be footed, tooled, pronged, or wrapped to support traction, stability, balance or positioning. The bottom end of the disclosed pole may be integral to the disclosed pole materials or affixed as a separate accessory using different materials such as leather, rubber, fiberglass, bone, or metal.
Accessories are contemplated that can affix, bind, tether, or connect two or more poles to one another for a variety of uses. For example, two or more poles can be connected together to create a seat, stretcher, bivouac, sledge, or fishing weir. More specifically, combined poles can thus be used as standing chairs in, for example, an office, as cots on emergency sites, or any number of uses in various environments. Furthermore, combined poles can be used as backpack props while a wearer is standing with a shouldered backpack. Connection components that can be used for backpacks, compatible seats, nets, or tenting can include loops, snags, tie-downs, or other fastening mechanisms, and poles can accessorize to respond as needed with any combination of holes, clips, notches, anchor points, and/or fasteners.
In some embodiments, the disclosed poles can be used during exercises to strengthen and stretch muscles and improve balance. The shape and structure of the disclosed poles can allow for a variety of resistance training. Therefore, in addition to their intuitive use for walking and hiking, the disclosed poles can be used by fitness, yoga, and Pilates practitioners to enhance workouts.
